(a)	Conversion of the Company Common Stock and the Merger Sub Common Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of any of the parties, or the holders of any shares of Company Common Stock:

(i)

Each issued and outstanding share of Company Common Stock (other than any shares of Company Common Stock to be cancelled pursuant to Section 3.1(b) and Dissenting Shares, if any) shall be converted into the right to receive: (A) such number of shares of Parent Common Stock equal to the Exchange Ratio multiplied by 1 (the Stock Consideration), and (B) an amount in cash equal to the result of (x) $170,000,000, divided by (y) the Fully Diluted Foxtrot Share Number, without interest (the Cash Consideration and, together with the Stock Consideration and the right to receive cash in lieu of fractional shares of Parent Common Stock as specified in Section 3.2(e) below, the Merger Consideration). As of the Effective Time, all such shares of Company Common Stock shall no

Page 6

longer be outstanding and shall automatically be cancelled and retired and shall cease to exist. As of the Effective Time, each holder of a Certificate or Book-Entry Share representing any shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive, upon the surrender thereof, the Merger Consideration in accordance with Section 3.2.

(ii)

Each share of common stock of Merger Sub, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time shall be cancelled and, in exchange for the cancellation of the shares of Merger Sub common stock and the provision of the aggregate Merger Consideration by Parent, the Surviving Corporation shall issue an equivalent number of fully paid and non-assessable shares of common stock, par value $0.01 per share, all of which shares shall be held by Parent, and which shall constitute the only outstanding shares of common stock of the Surviving Corporation immediately following the Effective Time.

(b)

Cancellation of Company Common Stock. Each share of Company Common Stock then owned by the Company or any wholly owned Subsidiary of the Company (or held in the treasury of the Company) immediately prior to the Effective Time, or held by Sibelco or any of its Subsidiaries immediately prior to the Effective Time, shall automatically be cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(c)

Adjustment to Merger Consideration. The Merger Consideration shall be adjusted appropriately to reflect the effect of any stock split, reverse stock split, share consolidation, share subdivision, share bonus issue or stock dividend (including any dividend or distribution of securities convertible into Company Common Stock or Parent Common Stock, as applicable), reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to the number of shares of Company Common Stock or Parent Common Stock issued and outstanding after the date hereof and prior to the Effective Time.

(d)	Treatment of the Company Options and Company Equity Awards.

(i)

As of the Effective Time, each Company Option outstanding immediately prior to the Effective Time, whether vested or unvested, shall be converted (as converted, a Converted Stock Option), by virtue of the Merger and without any action on the part of the holder of that Company Option, into an option exercisable for that number of shares of Parent Common Stock equal to the product of (A) the aggregate number of shares of Company Common Stock for which such Company Option was exercisable multiplied by (B) the Exchange Ratio, rounded down to the nearest whole share. The exercise price per share of such Converted Stock Option shall be equal to (x) the exercise price per share of such Company Option

Page 7

immediately prior to the Effective Time, divided by (y) the Exchange Ratio, rounded up to the nearest cent; provided, however that the exercise price and the number of shares of Parent Common Stock purchasable pursuant to a Converted Stock Option shall be subject to such adjustments as may be necessary for the foregoing conversion to satisfy the requirements of Sections 409A, 422 and 424 of the US Internal Revenue Code of 1986, as amended (the Code) and Treasury Regulation Section 1.424-1, as applicable, and in determining whether such adjustments are required, the Merger Consideration will be considered fair market value of a share of Company Common Stock.

(ii)

As of the conversion pursuant to Section 3.1(d)(i), each Converted Stock Option shall have, and be subject to, the same terms and conditions (including any continuing vesting requirements) set forth in the applicable Company Equity Plan and the option agreement pursuant to which the corresponding Company Option was granted, as in effect immediately prior to the Effective Time; except, that if the employment of a holder of a Converted Stock Option is terminated without Cause or if the holder terminates his or her employment for Good Reason during the Award Protection Period, such holder’s unvested and unexcerciseable Converted Stock Options will become fully vested and exercisable upon such termination of employment. Further, all vested Converted Stock Options will remain exercisable for a minimum period of 12 months following the holder’s termination of employment at any time and for any reason other than for Cause, or, if earlier, until the original expiration date of the Converted Stock Option.

In addition, at or prior to the Effective Time, Parent or Merger Sub shall deposit or cause to be deposited with the Exchange Agent, for the benefit of holders of shares of Company Common Stock, (i) shares of Parent Common Stock representing the aggregate amount of shares of Parent Common Stock sufficient to deliver the Stock Consideration, in the aggregate, to all persons entitled thereto; and (ii) immediately available funds sufficient to pay the Cash Consideration, in the aggregate, to all holders of Company Common Stock

Page 12

pursuant to Section 3.1(a)(i)(B) persons entitled thereto (such cash and shares, together with any dividends or distributions with respect thereto, hereinafter, the Exchange Fund). The Exchange Agent shall deliver the Merger Consideration to be issued pursuant to Section 3.1 out of the Exchange Fund. Parent shall consult with, and consider in good faith the views of, the Company in relation to the selection of the Exchange Agent. The Company shall have the right to approve the selection of the Exchange Agent, and the Contract pursuant to which Parent or Merger Sub shall appoint the Exchange Agent shall be in form and substance reasonably acceptable to the Company.

(b)	Exchange Procedures.

(i)

As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate (a Certificate) or book-entry share (a Book-Entry Share) that immediately prior to the Effective Time represented outstanding shares of Company Common Stock, whose shares were converted into the right to receive the Merger Consideration, (A) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates or Book-Entry Shares to the Exchange Agent, and which shall be in such form and have such other provisions as Parent may reasonably specify) and (B) instructions for use in effecting the surrender of the Certificates and Book-Entry Shares in exchange for the Merger Consideration. Upon surrender of a Certificate or Book-Entry Share, as applicable, for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by Parent, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Certificate or Book-Entry Share shall be entitled to receive in exchange therefor that number of whole shares of Parent Common Stock and that amount of cash (including cash in lieu of fractional shares as provided in Section 3.2(e)) that such holder has the right to receive pursuant to the provisions of this ARTICLE III, and the Certificate or Book-Entry Share so surrendered shall forthwith be cancelled. If any portion of the Merger Consideration is to be registered in the name of, or paid to, a person other than the person in whose name the applicable surrendered Certificate or Book-Entry Share is registered, it shall be a condition to the registration or payment (as applicable) of such Merger Consideration that the surrendered Certificate or Book-Entry Share shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such delivery of the Merger Consideration shall pay to the Exchange Agent any transfer or other taxes required by reason of such registration in the name of a person other than the registered holder of such Certificate or Book-Entry Share or establish to the reasonable satisfaction of the Exchange Agent that such tax has been paid or is not applicable.

Page 13

(ii)

Until surrendered as contemplated by this Section 3.2, each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration. No interest shall be paid or shall accrue for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration payable upon the surrender of Certificates or Book-Entry Shares.

(c)

Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate or Book-Entry Share with respect to any shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to Section 3.2(e), in each case until the surrender of such Certificate or Book-Entry Share in accordance with this ARTICLE III. Subject to Applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be paid to the holder of shares of Parent Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of a fractional share of Parent Common Stock to which such holder is entitled pursuant to Section 3.2(e), (ii) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such shares of Parent Common Stock, and (iii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender and a payment date subsequent to such surrender payable with respect to such shares of Parent Common Stock.

(d)

No Further Ownership Rights in Company Common Stock. All shares of Parent Common Stock issued and cash paid upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this ARTICLE III (including any cash paid pursuant to Section 3.2(e)) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Company Common Stock, theretofore represented by such Certificates or Book-Entry Shares, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares are presented to Parent or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this ARTICLE III, except as otherwise provided by Applicable Law.

(e)	Fractional Shares.

(i)

No certificates or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares, no dividends or other distributions with respect to Parent Common Stock shall be payable on or with respect to such fractional share interests and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a holder of Parent Common Stock.

Page 14

(ii)

Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after aggregating all Certificates and Book-Entry Shares delivered by such holder) (each a Fractional Stockholder) shall receive, in lieu thereof, cash (in a US dollar amount), without interest, in an amount equal to such fraction as determined below. As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (i) the number of full shares of Parent Common Stock delivered to the Exchange Agent by Parent for issuance to holders of Certificates or Book-Entry Shares over (ii) the aggregate number of full shares of Parent Common Stock to be distributed to holders of Certificates or Book-Entry Shares (such excess, the Excess Shares). As soon as practicable after the Effective Time, the Exchange Agent, as agent for such holders of Certificates or Book-Entry Shares, shall sell the Excess Shares at then prevailing prices on the Exchange, all in the manner provided herein.

(iii)

The sale of the Excess Shares by the Exchange Agent shall be executed on the Exchange and shall be executed in round lots to the extent practicable. Until the net proceeds of any such sale or sales have been distributed to the Fractional Stockholders, the Exchange Agent shall hold such proceeds in trust for such Fractional Stockholders. The net proceeds of any such sale or sales of Excess Shares to be distributed to the holders of Certificates or Book-Entry Shares shall be reduced by any and all commissions, transfer taxes and other out-of-pocket transaction costs, as well as any expenses, of the Exchange Agent incurred in connection with such sale or sales. The Exchange Agent shall determine the portion of such net proceeds to which each holder of Certificates or Book-Entry Shares shall be entitled, if any, by multiplying the amount of the aggregate net proceeds by a fraction, (A) the numerator of which is the amount of the fractional share interest to which such holder of Certificates or Book-Entry Shares is entitled (after taking into account all Certificates and Book-Entry Shares then held by such holder) and (B) the denominator of which is the aggregate amount of fractional share interests to which all holders of Certificates or Book-Entry Shares are entitled. As soon as practicable after the determination of the amount of cash, if any, to be paid to holders of Certificates or Book-Entry Shares with respect to any fractional share interests, the Exchange Agent shall promptly pay such amounts to such holders subject to and in accordance with this Section 3.2(e).

(iv)

Notwithstanding the provisions of this Section 3.2(e), Parent may elect, at its option exercised prior to the Effective Time, to pay the Exchange Agent an amount in cash in US dollars, to be deposited on the first

Page 15

Business Day following the Effective Time, sufficient for the Exchange Agent to pay each holder of Certificates or Book Entry Shares an amount in cash equal to the product obtained by multiplying (A) the fraction of a share of Parent Common Stock to which such holder would have otherwise been entitled by (B) the closing price for a single share of Parent Common Stock on the Exchange on the first Business Day immediately following the Effective Time. In such event, all references in this Agreement to the net proceeds from the sale of Excess Shares and similar references shall be deemed to refer to the payment executed in the manner set forth in this Section 3.2(e)(iv).

(f)

Return of Merger Consideration. Any portion of the Merger Consideration made available to the Exchange Agent pursuant to Section 3.2(a) that remains undistributed to the holders of the Certificates or Book-Entry Shares for one year after the Effective Time shall be delivered to Parent, upon demand, and any holders of the Certificates or Book-Entry Shares who have not theretofore complied with this ARTICLE III shall thereafter be entitled to look only to Parent for payment of their claim for any shares of Parent Common Stock, any cash (including cash in lieu of fractional shares of Parent Common Stock) and any dividends or distributions with respect to Parent Common Stock.

(g)

No Liability. None of the Company, Parent, Merger Sub, the Surviving Corporation or the Exchange Agent shall be liable to any person in respect of any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificate or Book-Entry Share has not been surrendered prior to seven years after the Effective Time, or immediately prior to such earlier date on which any shares of Parent Common Stock, any cash in lieu of fractional shares of Parent Common Stock or any dividends or distributions with respect to Parent Common Stock in respect of such Certificate or Book-Entry Share would otherwise escheat to, or be required to come into the custody of, any Governmental Entity, any such shares, cash, dividends or distributions in respect of such Certificate or Book-Entry Share shall, to the extent permitted by Applicable Law, become the property of Parent, free and clear of all claims or interests of any person previously entitled thereto.

(h)

Withholding Rights. Each of Parent, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld or paid over to or deposited with the relevant Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the person in respect of which such deduction and withholding was made.

Page 16

(i)

Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent or the Exchange Agent, the posting by such person of a bond in such reasonable amount as Parent or the Exchange Agent, as applicable, may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed Certificate, the applicable Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby, any cash in lieu of fractional shares of Parent Common Stock, and unpaid dividends and distributions on Parent Common Stock deliverable in respect thereof, pursuant to this Agreement.

Section 3.3 Effect of the Second Merger

As of the Second Effective Time, by virtue of the Second Merger and without any action on the part of any of the parties, or the holders of any shares of Company Common Stock, each share of Company Common Stock issued and outstanding immediately prior to the Second Effective Time shall be automatically cancelled and retired and shall cease to exist, and no consideration shall be delivered in exchange therefor.

For purposes of this Agreement, Company Alternative Transaction means any of (i) a transaction or series of transactions pursuant to which any person (or group of persons) other than Parent and its Subsidiaries (including Merger Sub and Merger Sub LLC) (such person (or group of persons), a Company Third Party), acquires or would acquire, directly or indirectly, beneficial ownership (as defined in Rule 13d-3 under the Exchange Act) of more than 20% of the issued and outstanding shares of Company Common Stock or securities (or options, rights or warrants to purchase, or securities convertible into or exchangeable for, such securities) representing 20% or more of the voting power of the Company, whether from the Company or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, consolidation, share exchange or similar transaction pursuant to which any Company Third Party acquires or would acquire, directly or indirectly, assets or businesses of the Company or any of its Subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a

Page 70

consolidated basis) of the Company and its Subsidiaries taken as a whole, (iii) any transaction pursuant to which any Company Third Party acquires or would acquire, directly or indirectly, control of assets (including for this purpose the outstanding equity securities of Subsidiaries of the Company and any entity surviving any merger or combination including any of them) of the Company or any of its Subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of the Company and its Subsidiaries taken as a whole or (iv) any disposition of assets to a Company Third Party representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of the Company and its Subsidiaries, taken as a whole.

(b)

Except as permitted by Section 5.2(a), Section 5.2(c) or Section 5.2(d), neither the Board of Directors of the Company nor any committee thereof shall (i) withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify, or fail to make, including in the Proxy Statement, in each case in a manner adverse to Parent, the approval or recommendation by such Board of Directors or such committee of the Merger or this Agreement, (ii) approve or recommend, or propose publicly to approve or recommend, any Company Alternative Transaction (any action in clause (i) or this clause (ii) being referred to as a Company Recommendation Change), or (iii) cause the Company or any of its Affiliates to enter into any letter of intent, agreement in principle, acquisition agreement or other agreement related to any Company Alternative Transaction.

(c)

Notwithstanding the foregoing, in the event that, prior to obtaining the Company Stockholder Approval, the Board of Directors of the Company determines in good faith, after it has received a Company Superior Proposal (and after consultation with outside counsel and a financial advisor of nationally recognized reputation), that the failure to do so would be reasonably likely to be inconsistent with its fiduciary duties under Applicable Law, the Board of Directors of the Company may (subject to compliance with this and the following sentences) effect a Company Recommendation Change and/or cause the Company to terminate this Agreement pursuant to Section 8.1(f) and concurrently with such termination enter into a definitive agreement providing for such Company Superior Proposal, but only at a time that is after the fifth (5^th) Business Day following Parent’s receipt of written notice from the Company advising Parent that the Board of Directors of the Company has received a Company Superior Proposal specifying the material terms and conditions of such Company Superior Proposal, identifying the person making such Company Superior Proposal and stating that it intends to make a Company Recommendation Change and/or terminate this Agreement pursuant to Section 8.1(f); provided that in the event of a subsequent modification to the material terms and conditions of such Company Superior Proposal, the Board of Directors of the Company may only effect a Company Recommendation Change and/or terminate this Agreement pursuant to Section 8.1(f) after the third (3^rd) Business Day following Parent’s receipt of written notice from the Company advising Parent of the modification to such terms and conditions; and provided further that during the foregoing notice periods, as applicable, the Company engages (to the extent requested by Parent) in good faith

Page 71

negotiations with Parent to amend this Agreement in such a manner that the proposal to enter into a Company Alternative Transaction no longer constitutes a Company Superior Proposal.

For purposes of this Agreement, a Company Superior Proposal means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a Company Third Party to enter into a Company Alternative Transaction (with all references to 20% in the definition of Company Alternative Transaction being treated as references to 50% for these purposes) that (A) did not result from a material breach of Section 5.2(a), and (B) is on terms that the Board of Directors of the Company determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be more favorable to the Company’s stockholders to the Transactions, taking into account all relevant factors (including any changes to this Agreement that may be proposed by Parent in response to such proposal to enter into a Company Alternative Transaction, and the relative likelihood that such Company Alternative Transaction would be completed, taking into account all financial, regulatory, legal and other aspects of such proposal).

(d)

In addition, notwithstanding anything in this Agreement to the contrary, at any time prior to the receipt of the Company Stockholder Approval, if the Board of Directors of the Company determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) that the failure to do so would be reasonably likely to be inconsistent with its fiduciary duties under Applicable Law, the Board of Directors of the Company may effect a Company Recommendation Change in response to any Effect that materially affects (A) the business, financial condition or results of operations of the Company and its Subsidiaries, taken as a whole, or (B) the stockholders of the Company (including the benefits of the Transactions to the Company or the stockholders of the Company), in either case that (x) is first occurring after the date hereof, (y) does not involve or relate to a proposal the consummation of which would constitute a Company Alternative Transaction, and (z) is not known and was not reasonably foreseeable to the Board of Directors of the Company as of the date hereof, but only at a time that is after the third business day following Parent’s receipt of written notice from the Company advising Parent of all material information with respect to any such Effect and stating that it intends to make a Company Recommendation Change and providing a full description of its rationale therefor.

(e)

In addition to the obligations of the Company set forth in Section 5.2(a) and Section 5.2(b), the Company shall as promptly as reasonably practicable after receipt thereof, advise Parent in writing of any request for information or of any proposal relating to a Company Alternative Transaction, the material terms and conditions of such request or proposal (including any changes thereto) and the identity of the person making such request or proposal. The Company shall (i) keep Parent reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a reasonably current

Page 72

basis and (ii) provide to Parent as soon as reasonably practicable after receipt or delivery thereof copies of all correspondence and other written materials exchanged between the Company or its Subsidiaries or any of their Representatives, on the one hand, and any person making such request or proposal, on the other hand, in each case to the extent that such correspondence or other written materials describes in any material respect any of the material terms or conditions of any such request or proposal (including any material change to any material term).

(f)

Nothing contained in this Section 5.2 shall prohibit the Company from taking and disclosing to its stockholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act, or from issuing a “stop, look and listen” statement or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act pending disclosure of its position thereunder; provided, however, that any such disclosure or statement that constitutes or contains a Company Recommendation Change shall be subject to the provisions of Section 5.2(b) (it being understood, for the avoidance of doubt, that a disclosure that constitutes only a “stop, look and listen” statement or similar communication of the type contemplated by Rule 14d-9(f) under the Exchange Act shall not be deemed to be a Company Recommendation Change).

ARTICLE VI

Parent and the Company shall cooperate and provide the other party and its counsel with a reasonable opportunity to review and comment on any amendment or supplement to the Registration Statement prior to filing such with the SEC, and with a copy of all such filings made with the SEC. Notwithstanding any other provision herein to the contrary, no amendment or supplement (including by incorporation by reference) to the Proxy Statement or the Registration Statement shall be made without the approval of both Parent and the Company, which approval shall not be unreasonably withheld, conditioned or delayed; provided that this right of approval shall not apply with respect to documents filed by the Company that are incorporated by reference in the Registration Statement, and provided, further, that this approval right shall not apply with respect to information relating to a Company Recommendation Change.

(c)

Each of Parent and the Company shall advise the other, promptly after it receives notice thereof, of the time when the Registration Statement has become effective or any supplement or amendment has been filed, the issuance of any stop order, or any request by the SEC for amendment of the Registration Statement or comments thereon and responses thereto or requests by the SEC for additional information. If at any time prior to the Effective Time any information relating to the Company, Sibelco, Parent, or any of their respective Affiliates, officers or directors, should be discovered by the Company, Sibelco or Parent that should be set forth in an amendment or supplement to the Registration Statement, so that any part of such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by Applicable Law, disseminated to the stockholders of the Company.

(d)	The Company shall use reasonable best efforts to cause the Proxy Statement to be mailed to the Company’s stockholders as promptly as practicable after the Registration Statement Effective Date.

Subject to the Company’s right to terminate this Agreement pursuant to Section 8.1(f), the Company’s obligation to give notice of, convene and hold the Company Stockholders Meeting in accordance with this Section 6.2 shall not be limited or otherwise affected by the making, commencement, disclosure, announcement or submission of any Company Superior Proposal or by a Company Recommendation Change. The Company may only postpone or adjourn the Company Stockholders

Page 74

Meeting (i) if necessary to solicit additional proxies for the purpose of obtaining the Company Stockholder Approval, (ii) for the absence of a quorum or (iii) to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that the Company has determined after consultation with outside legal counsel is reasonably likely to be required under Applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by stockholders of the Company prior to the Company Stockholders Meeting; provided, however, that the Company shall postpone or adjourn the Company Stockholders Meeting once up to the earlier of (a) twenty (20) days or (b) the date that is the latest date legally permissible under Applicable Law without having to set a different record date for the Company Stockholders Meeting upon the request of Parent if necessary to solicit additional proxies for the purpose of obtaining the Company Stockholder Approval.

Section 6.3 Financing; Financing Cooperation.

(a)

Subject to the terms and conditions of this Agreement, Parent will not permit any amendment or modification to, or any termination, rescission or withdrawal of, or any material waiver of any provision or remedy under, the Debt Commitment Letter or the definitive agreements with respect thereto (such definitive agreements related to the Financing, collectively, with the Debt Commitment Letter, the Definitive Agreement) or the fee letter referred to in the Debt Commitment Letter, if such amendment, modification or waiver (individually or in the aggregate with any other amendments, modifications or waivers) would reasonably be expected to (i) reduce the aggregate amount of the Financing under any Definitive Agreement below the amount required to consummate the Transactions (including by changing the amount of fees to be paid or original issue discount thereof), or (ii) impose any new or additional condition, or otherwise amend, modify or expand any condition, to the receipt of any portion of the Financing in a manner that would reasonably be expected to (A) delay or prevent the Closing, (B) make the funding of any portion of the Financing (or satisfaction of any condition to obtaining any portion of the Financing) less likely to occur, (C) adversely impact the ability of Parent to enforce its rights against any other party to any Definitive Agreement or (D) adversely impact the ability of Parent to consummate the Transactions or the likelihood of the consummation of the Transactions. In addition to the foregoing, Parent shall not release or consent to the termination of the Debt Commitment Letter except for (x) assignments and replacements of an individual lender under the terms of the syndication of the Financing under the Debt Commitment Letter, or (y) replacements of the Debt Commitment Letter with alternative financing commitments pursuant to Section 6.3(b).

(b)

Parent shall use (or cause its Subsidiaries to use) its reasonable best efforts to take all actions and do, or cause to be done, as promptly as possible, all things necessary, proper or advisable to arrange the Financing and obtain the financing contemplated thereby on the terms and conditions set forth in the Debt Commitment Letter (including, to the extent required, the exercise of any flex provisions), including using its reasonable best efforts to (i) maintain in effect the

Page 75

Debt Commitment Letter in accordance with the terms and subject to the conditions thereof, (ii) comply with its obligations under the Debt Commitment Letter, (iii) negotiate, execute and deliver definitive agreements with respect to the Financing contemplated by the Debt Commitment Letter on the terms and conditions (including the flex provisions) contemplated by the Debt Commitment Letter or on other terms that are (A) acceptable to the Lenders and (B) in the aggregate not materially less favorable, taken as a whole, to Parent, (iv) satisfy on a timely basis (or obtain a waiver to) all conditions to funding that are applicable to Parent and its Subsidiaries in the Debt Commitment Letter and the definitive agreements with respect to the Financing contemplated by the Debt Commitment Letter, (v) enforce its rights under the Debt Commitment Letter, (vi) consummate the Financing at or prior to the Closing, and (vii) cause the Lenders to fund the Financing at the Closing. Parent will fully pay, or cause to be fully paid, all commitment or other fees arising pursuant to the Debt Commitment Letter as and when they become due. In furtherance and not in limitation of the foregoing, in the event that any portion of the Financing becomes (or would reasonably be expected to become) unavailable on the terms and conditions (including the flex provisions) set forth in the Debt Commitment Letter, Parent shall use its reasonable best efforts to, as promptly as reasonably practicable following the occurrence of such event, (1) obtain alternative financing from alternative sources on terms and conditions not less favorable in the aggregate to Parent than those set forth in the Debt Commitment Letter and in an amount at least equal to the Financing or such unavailable portion thereof, as the case may be (the Alternate Financing), and (2) obtain one or more new financing commitment letters with respect to such Alternate Financing (the New Debt Commitment Letters), which New Debt Commitment Letters will replace the existing Debt Commitment Letter in whole or in part. Parent shall promptly provide the Company with a copy of any New Debt Commitment Letters (and any redacted fee letter in connection therewith). In the event that any New Debt Commitment Letters are obtained, (x) any reference in this Agreement to the “Debt Commitment Letter” will be deemed to include the Debt Commitment Letter to the extent not superseded by a New Debt Commitment Letter at the time in question and any New Debt Commitment Letters to the extent then in effect, and (y) any reference in this Agreement to the “Financing” means the debt financing contemplated by the Debt Commitment Letter as modified pursuant to the foregoing.

(c)

Parent shall (i) keep the Company reasonably informed on a reasonably current basis of the status of its efforts to arrange the Financing, and (ii) provide the Company with copies of all executed definitive agreements related to the Financing. Without limiting the generality of the foregoing, Parent shall promptly notify the Company (A) of any material breach or default by any party to the Debt Commitment Letter or definitive agreements related to the Financing, or (B) of the receipt by Parent of any written notice or communication from any Lender with respect to any (1) breach, default, termination or repudiation by any party to the Debt Commitment Letter or any definitive agreements related to the Financing of any provisions of the Debt Commitment Letter or such definitive agreements, (2) material dispute or disagreement between or among any parties to the Debt

Page 76

Commitment Letter or any definitive agreements related to the Financing but only to the extent that the Parent believes in good faith that (X) it will not be able to obtain any portion of the Financing as a result of such dispute or disagreement or (Y) the Closing could reasonably be expected to be delayed or prevented as a result of such dispute or disagreement, (3) if and when Parent becomes aware that any portion of the Financing contemplated by the Debt Commitment Letter may not be available, (4) if for any reason Parent believes in good faith that it will not be able to obtain any portion of the Financing on the terms, in the manner and from the sources contemplated by the Debt Commitment Letter (including any related flex terms) and (5) of any expiration or termination of the Debt Commitment Letter or other Definitive Agreement; provided that any information disclosed in such notice shall be subject to the Confidentiality Agreement.

(d)

Prior to the Effective Time, the Company will use its reasonable best efforts, and will cause each of its Subsidiaries to use their respective reasonable best efforts, to provide, to the extent within its control, Parent (at Parent’s sole expense) with all cooperation reasonably requested by Parent to assist it in causing the conditions in the Debt Commitment Letter to be satisfied or as is otherwise necessary for the arrangement and consummation of the Financing and reasonably requested by Parent in connection with the Financing (provided that such cooperation does not unreasonably interfere with the ongoing operations of the Company and its Subsidiaries), including using its reasonable best efforts to:

(i)

participate (and using reasonable best efforts to cause senior management and Representatives, with appropriate seniority and expertise, of the Company, to participate) in a reasonable and limited number of meetings, presentations, road shows, due diligence sessions, sessions with prospective financing sources, drafting sessions and sessions with rating agencies, and otherwise cooperating with the marketing efforts for any of the Financing;

(ii)

promptly (x) provide Parent and the Lenders with the Required Information; provided that the filing of the required financial statements on Form 10-K and Form 10-Q within the time periods set forth in Required Information by the Company will satisfy the requirements of this clause with respect to annual and quarterly financials, and (y) assist Parent and the Lenders (i) with the timely preparation of customary rating agency presentations, bank information memoranda, marketing materials and similar documents required in connection with the Financing and (ii) by providing customary financial information as reasonably requested by Parent to enable Parent to prepare forecasts of financial statements of the Company for one or more periods following the Closing, in each case, to the extent customary and reasonably required pursuant to such Financing and to the extent reasonably available;

Page 77

(iii)

assist Parent in connection with the preparation (but not executing, unless effective until the Effective Time) any pledge and security documents and other definitive financing documents as may be reasonably requested by Parent or the Lenders (including using reasonable best efforts to obtain consents of accountants for use of their reports in any materials relating to the Financing and accountants’ comfort letters, in each case as reasonably requested by Parent), and otherwise reasonably facilitating the pledging of collateral and the granting of security interests in respect of the Financing (including obtaining and delivering any pay-off letters and other cooperation in connection with the repayment or other retirement of existing indebtedness and the release and termination of any and all related liens), it being understood that such documents will not take effect until the Effective Time;

(iv)

cooperate with any marketing efforts of Parent and the Lenders for any portion of the Financing (including providing executed customary authorization letters to the Lenders authorizing the distribution of information related to the Company and its Subsidiaries to prospective lenders or investors and containing a representation to the Lenders that the public side versions of such documents, if any, do not include material non-public information about the Company or its Subsidiaries or securities and executing ratings agency engagement letters as required in connection with the Financing (provided, that the Company shall not be required to pay any cost or expenses relating to rating agency engagement letters));

(v)

take all corporate and other actions, subject to the occurrence of the Closing, reasonably requested by Parent to permit the consummation of the Financing;

(vi)

furnishing Parent and the Lenders with all documentation and other information required by regulatory authorities pursuant to applicable “know your customer” and anti-money laundering rules and regulations at least three Business Days prior to the Closing Date, provided that the request for such information has been made at least ten Business Days prior to the Closing Date; and

(vii)

use reasonable best efforts to ensure that any syndication efforts in connection with the Financing benefit from the Company’s and its Subsidiaries’ existing lending and investment banking relationships.

(e)

Notwithstanding the provisions of Section 6.3(d), nothing in this Agreement will require the Company or any of its Subsidiaries to (i) waive or amend any terms of this Agreement or agree to pay any fees, incur any liability or reimburse any expenses prior to the Effective Time for which it has not received prior reimbursement or is not otherwise indemnified (in a manner reasonably acceptable to the Company) by or on behalf of Parent, in each case in connection with the Financing, (ii) enter into any definitive agreement with respect to the Financing (other than with respect to customary authorization letters and ratings agency engagement letters referred to in Section 6.3(d)(iv)) that is effective prior

Page 78

to the Closing, (iii) give any indemnities in connection with the Financing that are effective prior to the Effective Time, (iv) provide in connection with the Financing any information the disclosure of which is prohibited or restricted under Law or is legally privileged, (v) the pre-Closing Board of Directors of the Company and the directors, managers and general partners of the Company’s Subsidiaries shall not be required to adopt resolutions approving the agreements, documents and instruments pursuant to which the Financing is obtained, (vi) neither the Company nor any of its Subsidiaries shall be required to take any corporate actions prior to the Closing to permit the consummation of the Financing, and (vii) none of the Company or any of its Subsidiaries shall be required to provide, and Parent shall be solely responsible for, (A) the preparation of pro forma financial information, including pro forma cost savings, synergies, capitalization or other pro forma adjustments desired to be incorporated into any pro forma financial information, (B) any description of all or any component of the Financing, including any such description to be included in any liquidity or capital resources disclosure or any “description of notes”, (C) projections, risk factors or other forward-looking statements relating to all or any component of the Financing, (D) Subsidiary financial statements or any other information of the type required by Rule 3-09, Rule 3-10 or Rule 3-16 of Regulation S-X, (E) Compensation Disclosure and Analysis required by Item 402(b) of Regulation S-K, or (F) any solvency certificate or similar certification or representation. Nothing in this Section 6.3 will require (1) any officer or Representative of the Company or any of its Subsidiaries to deliver any certificate or opinion or take any other action pursuant to Section 6.3(d) that could reasonably be expected to result in personal liability to such officer or Representative, or (2) the members of the Company Board as of immediately prior to the Effective Time to approve any financing or Contracts related thereto.

(f)

Subject to Parent’s indemnification obligations under this Section 6.3, the Company hereby consents to the use of all logos of the Company and its Subsidiaries in connection with the Financing so long as such logos (i) are used solely in a manner that is not intended to or likely to harm or disparage the Company or any of its Subsidiaries or the reputation or goodwill of the Company or any of its Subsidiaries and (ii) are used solely in connection with a description of the Company, its business and operations or the Transactions.

(g)

Parent shall promptly reimburse the Company and its Subsidiaries for all out-of-pocket costs and expenses (including reasonable legal fees and expenses) incurred by the Company and/or any of its Subsidiaries in connection with providing the support and cooperation contemplated by this Section 6.3. Parent shall indemnify and hold harmless the Company and its Subsidiaries, and each of their respective directors, officers, employees, agents and other representatives, from and against any and all losses, damages, claims, interest, costs or expenses (including reasonable legal fees and expenses), awards, judgments, penalties and amounts paid in settlement suffered or incurred by any of them in connection with providing the support and cooperation contemplated by this Section 6.3 and any information utilized in connection therewith and any misuse of the logos or marks

Page 79

of the Company or its Subsidiaries (other than information provided by the Company or any of the Company’s Subsidiaries), except as a result of gross negligence or willful misconduct of the Company and its Subsidiaries, and each of their respective directors, officers, employees, agents and other representatives, as applicable.

(h)

Notwithstanding anything to the contrary in this Agreement, the condition set forth in Section 7.2(b), as it applies to the Company’s obligations under this Section 6.3, shall be deemed satisfied unless the Company has materially breached its obligations under this Section 6.3 and such breach has been the primary cause of the Financing not being obtained.

Section 6.4 Access to Information; Confidentiality

Subject to the Confidentiality Agreement and subject to Applicable Law, upon reasonable notice, each of the Company and Parent shall, and shall cause each of its respective Subsidiaries to, afford to the other party and to the officers, employees and Representatives of such other party, reasonable access, during normal business hours during the period from the date of this Agreement to the Effective Time, to all their respective properties, books, Contracts, commitments, personnel and records (provided that such access shall not unreasonably interfere with the business or operations of such party), and during such period, each of the Company and Parent shall, and shall cause each of its respective Subsidiaries to, furnish promptly to the other party all information concerning its business, properties and personnel as such other party may reasonably request (including in respect of developments in relation to key employees and material financial developments); provided, however, that the foregoing shall not require the Company and Parent to disclose any information pursuant to this Section 6.4 to the extent that (i) in the reasonable good faith judgment of such party, any Applicable Law requires such party or its Subsidiaries to restrict or prohibit access to any such information, (ii) in the reasonable good faith judgment of such party, the information is subject to confidentiality obligations to a third party or (iii) disclosure of any such information or document would result in the loss of attorney-client privilege; provided, further, that with respect to clauses (i) through (iii) of this Section 6.4, the Company, or Parent or Sibelco, as applicable, shall use its reasonable best efforts to (1) obtain the required consent of any third party necessary to provide such disclosure, (2) develop an alternative to providing such information so as to address such matters that is reasonably acceptable to the Company or Parent and (3) in the case of clauses (i) through (iii), utilize the procedures of a joint defense agreement or implement such other techniques if the parties determine that doing so would reasonably permit the disclosure of such information without violating Applicable Law or jeopardizing such privilege. No review pursuant to this Section 6.4 shall affect any representation or warranty given by the other party hereto. Each of the Company and Parent shall hold, and shall cause its respective Affiliates, officers, employees and Representatives to hold, any nonpublic information in accordance with the terms of the Confidentiality Agreement. Notwithstanding anything to the contrary contained in this Agreement, without the prior written consent of the other parties to this Agreement (which shall not be unreasonably withheld, conditioned or delayed), no party to this Agreement shall have any right to perform environmental or other invasive or subsurface samples, tests or investigations of the properties or facilities of the other parties or any of their respective Subsidiaries.

Section 6.5 Reasonable Best Efforts

(a)

Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, as soon as possible following the date hereof, the Transactions, including using reasonable best efforts in (i) causing all of the conditions set forth in ARTICLE VII to be satisfied, (ii) the obtaining of all necessary actions or non-actions, waivers, consents and approvals from Governmental Entities, including under the Antitrust Laws (the Required Consents) prior to the Effective Time, (iii) the obtaining of all consents, registrations, approvals, permits, authorizations and waivers necessary, proper or advisable to be obtained from, or renewed with third parties, (iv) the obtaining of all consents, approvals and authorizations under any Contract listed on Section 6.5(a)(iv) of the Company Disclosure Schedule; provided, that, the failure to obtain any of the consents, registrations, approvals, permits or authorizations referenced in clauses (ii) or (iv) above (other than any consents, approvals or events required pursuant to Section 7.1(b)) shall not constitute the failure to satisfy a condition to the obligation of either party to consummate the Transactions, (v) the execution and delivery of any additional instruments necessary to consummate the Transactions, and to fully carry out the purposes of, this Agreement, (vi) refraining from taking any action that would reasonably be expected to impede, interfere with, prevent or materially delay the consummation of the Merger and (vii) unless there has been a Company Recommendation Change made in compliance with Section 5.2(b) (in the case of the Company’s obligation to use its reasonable best efforts), obtaining the Company Stockholder Approval; provided, however, that efforts in connection with the Financing shall be governed by Section 6.3 and not this Section 6.5.

(b)

In furtherance and not in limitation of the foregoing, each of the Company, Parent, Merger Sub, Merger Sub LLC and Sibelco agrees to (i) make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the Transactions as promptly as practicable and, in any event, prior to January 5, 2018, (ii) make all filings listed on Section 6.5(b) of the Company Disclosure Schedule as promptly as practicable, and (iii) make all filings with other Governmental Entities relating to the Merger, and, in each case, supply as promptly as practicable any additional information and documentary material that may be formally or informally requested pursuant to the Antitrust Laws or by such authorities. Each of the parties shall use reasonable best efforts to cause the expiration or termination of any applicable waiting periods under the Antitrust Laws and the receipt of the Required Consents as soon as practicable. Each of the parties agrees that the use of “reasonable best efforts” in this Section 6.5 shall include proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture, licensing, testing, zoning,

Page 81

Representatives shall have any further liability or obligation to the other parties relating to or arising out of this Agreement or the Transactions; provided that (x) the Confidentiality Agreement shall survive any termination of this Agreement in accordance with its terms and (y) payment of the Company Termination Fee shall not relieve either party from any liability or obligation under Section 6.7.

(f)

Each party further agrees that notwithstanding anything in this Agreement to the contrary, including Sections 8.2(a) and 8.2(h), in the event that all of the conditions set forth in Section 7.1 and Section 7.2 have been satisfied (other than those conditions that by their terms are to be satisfied at the Closing, each of which is fully capable of being satisfied at the Closing) and the Financing is not funded by the date required pursuant to Section 1.2 hereof, (i) the sole and exclusive remedies of the Company and any of its Subsidiaries, equityholders, Affiliates, officers, directors, employees and Representatives against Sibelco, Parent or any of their respective Representatives or Affiliates, including where Sibelco, Parent, Merger Sub or Merger Sub LLC breaches this Agreement or fails to perform hereunder (whether willfully, intentionally, unintentionally, through a Willful Breach or otherwise), shall be (A) specific performance of Sibelco and Parent’s obligations solely under Section 6.3 in accordance with Section 9.9(a), (B) termination of this Agreement and payment of the Parent Termination Fee pursuant to, and in accordance with, Section 8.1(h) hereof (and the right to specifically enforce Parent’s obligation to pay the Parent Termination Fee pursuant to Section 9.9(a) hereof) or (C) in the case of a Willful Breach, a claim against Parent for damages; (ii) except as set forth in clause (i)(C) above, in no event will the Company or any of its Subsidiaries, equityholders, Affiliates, officers, directors, employees or Representatives (A) be entitled to seek or obtain any recovery or judgment in excess of the Parent Termination Fee against Sibelco, Parent or any of their respective Representatives or Affiliates, or any of their assets, or (B) seek to recover any other damages (including consequential, special, indirect or punitive damages) or seek any other remedy based on a claim in law or equity against Sibelco, Parent or any of their respective Representatives or Affiliates, and the Company, on its own behalf and on behalf each of its Subsidiaries, equityholders, Affiliates, officers, directors, employees and Representatives, hereby irrevocably and unconditionally waives any and all rights to any such claim or recovery, in each case of clauses (A) and (B), in respect of (x) any loss suffered, directly or indirectly, as a result of the failure of the Merger to be consummated, (y) the termination of this Agreement, (z) any liabilities or obligations arising under this Agreement, or (xx) any claims or actions arising out of or relating to any breach, termination or failure of performance under this Agreement, and (iii) upon payment of the Parent Termination Fee, as applicable, in accordance with this Section 8.2, none of Sibelco, Parent or any of their respective Affiliates or Representatives shall have any further liability or obligation to the Company relating to or arising out of this Agreement or the Transactions.

Page 98

(g)

The parties acknowledge and agree that the amount of the overall loss that Parent or the Company may incur in the circumstances in which the Company Termination Fee or the Parent Termination Fee, as applicable, is payable under this Section 8.2 is not possible to ascertain as at the date of this Agreement and that, as such, the Company Termination Fee and the Parent Termination Fee represent genuine estimates by the parties of the amount of the overall loss that Parent or the Company, as the case may be, would incur in the circumstances in which the Company Termination Fee or the Parent Termination Fee is payable.

(h)

Subject to Section 9.9(b), the last sentence of Section 8.2(f) and the last sentence of Section 9.9(c), no party will be relieved or released from liability for fraud or damages of any kind suffered by the other parties, including consequential damages and any other damages (whether or not communicated or contemplated at the time of execution of this Agreement), to the extent arising out of any Willful Breach of any of its representations, warranties, covenants or agreements contained in this Agreement, and, in each case, the aggrieved party will be entitled to all rights and remedies available at law or in equity; provided, however, that no party shall be liable for any damages in respect of, for the avoidance of doubt, any loss of the benefit of the Transactions to such party’s stockholders, any stockholder premium or any other benefit to such party’s stockholders (provided further, however, that the limitation contained in such proviso shall not be construed to limit the rights and remedies available at law or in equity to any party hereto to recover its damages on its own behalf, without regard to whether such rights or remedies would indirectly constitute a benefit to such party’s stockholders).

Section 8.3 Amendment

Subject to compliance with Applicable Law, this Agreement may be amended by the parties at any time before or after the Company Stockholder Approval; provided, however, that (a) after any such approval there may not be, without further approval of the stockholders of the Company, any amendment of this Agreement that changes the amount or the form of the consideration to be delivered to the holders of Company Common Stock hereunder or that by Applicable Law otherwise expressly requires the further approval of the stockholders of the Company, (b) except as provided above, no amendment of this Agreement shall be submitted to be approved by the stockholders of the Company, and (c) notwithstanding anything herein to the contrary, Sections 9.6(a), 9.7, 9.10, 9.11 and 9.15 and this Section 8.3 (and any provision of this Agreement to the extent a modification, waiver or termination of such provision would modify the substance of any of the foregoing provisions) may not be modified, waived or terminated in a manner that is adverse in any respect to a Lender or other Lender Related Party without the prior written consent of such Lender or Lender Related Party, such consent to not be unreasonably withheld, delayed or conditioned. This Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties and duly approved by the parties’ respective Boards of Directors or a duly authorized committee thereof.

Section 8.4 Extension; Waiver

At any time prior to the Effective Time, a party hereto may, subject to the proviso of Section 8.3 (and for this purpose treating any waiver referred to below as an amendment), (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties of the other parties contained in this Agreement or in any document delivered pursuant to this Agreement, (c) waive compliance by the other party with any of the agreements or conditions contained in this Agreement or (d) waive the satisfaction of any of the conditions contained in this Agreement. No extension or waiver by the Company or Parent shall require the approval of the stockholders of the Company or the shareholders of Parent (other than Sibelco to the extent otherwise expressly required hereunder), respectively, unless such approval is required by Applicable Law. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Any extension or waiver given in compliance with this Section 8.4 or failure to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

ARTICLE IX

Section 9.1 Nonsurvival of Representations and Warranties

None of the representations and warranties in this Agreement or in any instrument or certificate delivered pursuant to this Agreement shall survive the Effective Time (provided, however, that for the avoidance of doubt such failure to survive the Effective Time shall not prejudice any party in recovering from insurers in respect of breaches thereof under the representation and warranty insurance policy described in Section 6.25, if obtained).

Section 9.7 Governing Law

This Agreement and all Actions (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of the Company, Sibelco, Parent, Merger Sub or Merger Sub LLC in the negotiation, administration, performance and enforcement thereof shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under any applicable principles of conflicts of laws thereof. Notwithstanding the foregoing, actions that may be based upon, arise out of or related to the Financing, the Debt Commitment Letter or the Definitive Agreements, or the negotiation, execution or performance of any documentation related thereto, shall be governed by and construed in accordance with the laws of the State of New York, regardless of the laws that might otherwise govern under any applicable principles of conflicts of laws thereof.

for borrowings and other obligations in connection with the Financing. Any purported assignment in violation of the preceding sentence shall be void. Subject to the preceding two sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the parties and their respective successors and assigns.

Section 9.9 Specific Enforcement; Damages.

(a)

The parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and (as an integral and essential part of the Transactions without which the parties would not have entered into this Agreement) to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 9.10 below, without proof of actual damages (and each party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity; provided, however, that, except as expressly provided in Section 9.9(c), the Company shall not be entitled to specifically enforce Sibelco’s, Parent’s, Merger Sub or Merger Sub’s LLC’s obligation, as applicable, to effect the Closing or the Merger or pay or issue the Merger Consideration. Subject to Section 9.9(c), the parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach. For the avoidance of doubt, the parties may pursue both a grant of specific performance to the extent permitted by this Section 9.9 and the payment of damages as contemplated by Section 8.2(a)(ii) and Section 8.2(h), but may not collect more than one such remedy.

(b)

Notwithstanding anything to the contrary herein, the Company agrees that it may only pursue a grant of specific performance (and, for the avoidance of doubt, will not seek any monetary award) against Sibelco in respect of its obligations under this Agreement. For the avoidance of doubt, such limitation shall not apply with respect to Parent and its Subsidiaries.

(c)

Notwithstanding anything in this Agreement to the contrary, it is acknowledged and agreed that the Company shall be entitled to specifically enforce the obligation of Sibelco, Parent, Merger Sub or Merger Sub’s LLC, as applicable, to effect the Closing and the Merger and to pay or issue the Merger Consideration on the terms and conditions set forth in this Agreement only if (i) all of the conditions set forth in Section 7.1 and Section 7.2 have been satisfied or waived by the party entitled to waive (other than those conditions that, by their terms, cannot be satisfied until Closing but which are fully capable of being satisfied at Closing), (ii) the Company has irrevocably confirmed in a written notice to Parent that the Company is ready, willing and able to consummate the Merger and that if

Page 114

specific performance is granted and the Financing (including any alternative debt financing in accordance with Section 6.3) is funded and the Parent complies with its obligations to effect the Closing pursuant to the terms of this Agreement, then the Closing will occur, (iii) the Financing (including any alternative debt financing in accordance with Section 6.3) has been funded, and (iv) Parent fails to consummate the Closing by the date the Closing is required to occur pursuant to Section 1.2. For the avoidance of doubt, under no circumstances shall the Company be permitted or entitle to receive both (1) such grant of specific performance to require the Parent or Sibelco to effect the Closing or the Merger or to pay or issue the Merger Consideration and (2) payment of the Parent Termination Fee or other damages to the Company.

Section 9.10 Jurisdiction

In any Action between the parties arising out of or relating to this Agreement or any of the transactions contemplated hereby, each of the parties (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware in and for New Castle County, Delaware or any federal court sitting in the State of Delaware; (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from such court; and (iii) agrees that it will not bring any such action in any court other than the Court of Chancery for the State of Delaware in and for New Castle County, Delaware, or any federal court sitting in the State of Delaware and appellate courts thereof.

However, the foregoing shall not limit the right of a party to effect service of process on the other party by any other legally available method. Notwithstanding the foregoing, each of the parties agree (on behalf of itself and its controlled Affiliates) that it will not bring or support any Action of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against the Lenders or any Lender Related Party in any way relating to this Agreement, the Financing or any of the transactions contemplated hereby or thereby, including any dispute arising out of or relating in any way to the Debt Commitment Letter or any other letter or contract related to the Financing or the performance thereof, in any forum other than any state or federal court sitting in the borough of Manhattan in the city of New York (and appellate courts thereof).

Section 9.11 WAIVER OF JURY TRIAL

EACH OF SIBELCO, PARENT, MERGER SUB, MERGER SUB LLC AND THE COMPANY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE FINANCING (INCLUDING ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR

(the Company) listed on the signature pages attached hereto (the Stockholders, and, collectively with Parent and Merger Sub, the Parties). Capitalized terms used and not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement (as defined below).

WHEREAS, concurrently with the execution and delivery of this Agreement, SCR-Sibelco NV., Parent, Merger Sub, Bison Merger Sub I, LLC, a Delaware limited liability company and wholly owned subsidiary of Parent (Merger Sub LLC), and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (the Merger Agreement), providing for, among other things and subject to the terms and conditions of the Merger Agreement: (i) a business combination through the merger of Merger Sub with and into the Company (the Merger), with the Company surviving the Merger as a wholly-owned subsidiary of Parent; and (ii) a further business combination through the second merger of the Company with and into Merger Sub LLC (the Second Merger and, together with the merger, the Mergers) immediately following the consummation of the Merger, with Merger Sub LLC surviving the Second Merger as a wholly-owned subsidiary of Parent.

WHEREAS, as of the Effective Date, each Stockholder is the record and beneficial owner of the number of shares of Company Common Stock set forth opposite such Stockholder’s name on EXHIBIT 1 attached hereto (each, including any such Additional Securities (as defined below) an Owned Share).

WHEREAS, as a condition and inducement to the willingness of Parent, Merger Sub and Merger Sub LLC to enter into the Merger Agreement and in furtherance of the Mergers, the Stockholders wish to enter into this Agreement.

NOW, THEREFORE, in consideration of the representations, warranties, covenants and agreements set forth in this Agreement and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the Parties agree as follows:

ARTICLE I

STOCKHOLDERS CONSENT;

AGREEMENT TO VOTE AND IRREVOCABLE PROXY

Section 1.1 Agreement to Vote

Each Stockholder hereby irrevocably and unconditionally agrees that, from the Effective Date until the earlier of (a) the time that the Company Stockholder Approval has been obtained and (b) termination of this Agreement in accordance with Section 4.1 (the Agreement Term), such Stockholder shall (i) take all such actions as may be reasonably required to cause each of such Stockholder’s Owned Shares to be present, in person or by proxy, at the Company Stockholders Meeting and (ii) at any Company

Stockholders Meeting vote (or cause to be voted), to the extent entitled to vote thereon, all of such Stockholder’s Owned Shares:

(A)

in favor of (I) adoption of the Merger Agreement and the Transactions, including the Mergers and (II) the approval of any proposal to adjourn such Company Stockholders Meeting to a later date if there are not sufficient votes for adoption of the Merger Agreement and the Transactions, including the Mergers; and

(B)

against (I) any Company Alternative Transaction, (II) any action that would reasonably be expected to result in a breach of or failure to perform any representation, warranty, covenant or agreement of the Company under the Merger Agreement or of such Stockholder under this Agreement, (III) any action that would reasonably be expected to prevent, impede, frustrate, interfere with, delay, postpone or adversely affect the consummation of the Mergers or the other Transactions (in contravention of the terms and conditions of the Merger Agreement), (IV) any merger agreement or merger (other than the Merger Agreement and the Mergers), consolidation, combination, material business transaction, sale of assets, reorganization, recapitalization, dissolution, liquidation or winding up of the Company or any Company Subsidiary, and (V) any amendment of the Company’s organizational documents that would reasonably be expected to impair the ability of the Company, Parent, Merger Sub or Merger Sub LLC to complete the Mergers, or that would or would reasonably be expected to prevent, impede, frustrate, interfere with, delay, postpone or adversely affect the consummation of the Mergers.

Section 1.2 Other Voting Rights

For the avoidance of doubt, except as expressly set forth in this Agreement, nothing in this Agreement shall limit the right of any Stockholder to vote in favor of, against, or abstain with respect to any matter presented to the Company’s stockholders not addressed by this Agreement.

Section 1.3 Grant of Irrevocable Proxy

Each Stockholder hereby irrevocably appoints Parent and any designee of Parent, and each of them individually, as such Stockholder’s proxy and attorney-in-fact, with full power of substitution and resubstitution, to vote at the Company Stockholders Meeting during the Agreement Term, with respect to such Stockholder’s Owned Shares as of the applicable record date, in each case solely to the extent and in the manner specified in Section 1.1 (the Proxy); provided, however, that such Proxy shall be effective if, and only if, the Stockholder has not delivered to the Secretary of the Company, at least two Business Days prior to the Company Stockholders Meeting, a duly executed proxy card directing that such Stockholder’s Owned Shares be voted in accordance with Section 1.1. The Proxy is given to secure the performance of the duties of each Stockholder under this Agreement, and its existence will not be deemed to relieve any Stockholder of such Stockholder’s obligations under this Agreement. The Proxy shall expire and be deemed revoked automatically at the expiration of the Agreement Term or in the event of termination of this Agreement pursuant to Section 4.1.

Section 1.4 Nature of Irrevocable Proxy

The Proxy granted by each Stockholder is irrevocable during the Agreement Term or until this Agreement is terminated pursuant to Section 4.1, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by any Stockholder with regard to such Stockholder’s Owned Shares and each Stockholder acknowledges that the Proxy constitutes an inducement for Parent, Merger Sub and Merger Sub LLC to enter into the Merger Agreement. The power of attorney granted by each Stockholder is a durable power of attorney and shall survive the bankruptcy, dissolution, death or incapacity of such Stockholder.

MISCELLANEOUS

Section 4.1 Termination of this Agreement

This Agreement, and all obligations, terms and conditions contained herein, shall automatically terminate without any further action required by any Party upon the earliest to occur of: (a) the termination of the Merger Agreement in accordance with its terms, (b) the Effective Time, and (c) the Board of Directors of the Company making a Company Recommendation Change. In addition to the foregoing, this Agreement may be terminated, (d) with respect to an individual Stockholder, (i) at any time by written consent of Parent and such Stockholder and (ii) by the Stockholder following any amendment, change or modification to the Merger Agreement affecting the Merger Consideration in a manner detrimental to the Stockholder or Article VII of the Merger Agreement or that would other otherwise have a material adverse effect on the Stockholder, or (e) with respect to all Stockholders, at any time by written consent of the Parties.

Section 4.2 Effect of Termination

In the event of termination of this Agreement pursuant to Section 4.1, this Agreement shall become void and of no effect with no liability on the part of any Party; provided, however, no such termination shall relieve any Party from any liability for any breach of this Agreement occurring prior to such termination and the provisions of this ARTICLE IV, shall survive any such termination. Notwithstanding the foregoing, termination of this Agreement shall not prevent any Party from seeking any remedies (at law or in equity) against any other Party for that Party’s breach of any of the terms of this Agreement prior to the date of termination.

Section 4.3 Entire Agreement; Assignment.

This Agreement (together with the Merger Agreement, to the extent referred to in this Agreement) and any documents delivered by the Parties in connection herewith constitute the entire agreement among the Parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. Other than as set forth in Section 4.12, nothing in this Agreement, express or implied, is intended to or shall confer upon any person other than the Parties any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by any Party without the prior written consent of the other Parties, and any such assignment without such prior written consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective permitted successors and assigns.

Section 4.4 Amendments and Waivers

This Agreement may only be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by each of the Parties, or in the case of a waiver, by the Party against whom the waiver is to be effective. No failure or delay by Parent, Merger Sub or Merger Sub LLC in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

Section 4.6 Governing Law; Jurisdiction; Waiver of Jury Trial

(a)

This Agreement and all Actions (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of Parent or Merger Sub in the negotiation, administration, performance and enforcement thereof shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under any applicable principles of conflicts of laws thereof.

(b)

In any Action between the Parties arising out of or relating to this Agreement or any of the transactions contemplated hereby, each of the Parties (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware in and for New Castle County, Delaware or any federal court sitting in the State of Delaware; (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from such court; and (iii) agrees that it will not bring any such action in any court other than the Court of Chancery for the State of Delaware in and for New Castle County, Delaware, or any federal court sitting in the State of Delaware and appellate courts thereof. Each Party irrevocably consents to the service of process outside the territorial jurisdiction of the courts referred to in this Section 4.6 in

any such Action by mailing copies thereof by registered or certified United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 4.5. However, the foregoing shall not limit the right of a Party to effect service of process on the other party by any other legally available method.

(c)	EACH STOCKHOLDER AND EACH OF PARENT AND MERGER SUB WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 4.7 Specific Performance

The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to Section 4.6 above, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

Section 4.8 Counterparts; Effectiveness

This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered (including by electronic transmission) to the other Parties.

Section 4.9 Headings

The headings in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 4.10 Severability

If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect and shall in no way be affected, impaired or invalidated. Upon a determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by Applicable Law in a mutually acceptable manner to the end that the Transactions are fulfilled to the fullest extent possible.

Section 4.11 Interpretation

When a reference is made in this Agreement to an Article, Section or Exhibit, such reference shall be to an Article or Section of, or an Exhibit to, this Agreement, unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. Any agreement, instrument or statute defined or referred to herein or in any agreement or instrument that is referred to herein means such agreement, instrument or statute as from time to time amended, modified or supplemented, unless otherwise specifically indicated. References to a person are also to its permitted successors and assigns. Unless otherwise specifically indicated, all references to dollars and $ will be deemed references to the lawful money of the United States of America.

Section 4.12 Publication

Each Stockholder hereby permits Parent, the Company and Merger Sub to publish and disclose in any documents or schedules filed with the SEC and any other disclosures or filings required by Applicable Law such Stockholder’s identity and ownership of the Owned Shares and the nature of such Stockholder’s commitments pursuant to this Agreement.

(i)

to ensure that the number of Directors constituting the Board is fixed and remains at all times at 11 Directors;

(III)

the Chief Executive Officer of the Company (the Executive Director), from time to time; and

(iii)

from and after the Trigger Date,

(A)

to cause the number of Sibelco Directors to at all times equal the product of Sibelco’s Proportional Ownership and the total number of Directors authorized to serve on the Board, rounded down to the nearest whole number (the Proportional Director Number) by the removal or resignation of the number of Sibelco Directors (the Removed Directors) necessary to reduce the total number of Sibelco Directors then serving on the Board to the Proportional Director Number; and

to nominate and vote to elect, subject to Section 2.2, the following individuals to serve as Directors:

(I)

the Proportional Director Number of individuals nominated by Sibelco (each such Director a “Sibelco Director” for purposes of this Agreement);

(c)

Board Composition Following Third Annual Meeting Date.

(A)

in the event such Director is a Sibelco Director, then the remaining Sibelco Directors shall have the right to designate an individual to fill such vacancy; and

(B)

in the event such Director is a Fairmount Director, then the remaining Fairmount Directors shall have the right to designate an individual to fill such vacancy; provided, however, that prior to the Trigger Date, if the remaining Fairmount Directors fail to designate in writing a representative to fill a vacancy created on the Board due to the death, disability, retirement, resignation or removal of a Fairmount Director and such failure shall continue for more than 30 days after notice of such failure from the Company to the remaining Fairmount Directors, then the vacant position shall be filled by an individual designated

-7-

by the Sibelco Directors then in office; provided further, that any such individual shall be removed from such position if the remaining Fairmount Directors so direct and simultaneously designate a new Fairmount Director, in accordance with the foregoing sentence; and the Company and each Stockholder (whether in his, her or its capacity as a stockholder, director, member of a board committee, officer of the Company or otherwise) hereby agree to take such actions as may be necessary or desirable within his, her or its control (including, in the case of a Stockholder, by voting all voting Shares owned by such Stockholder or over which such Stockholder has voting control) to ensure the election or appointment of such designee to fill such vacancy on the Board; and

(ii)

in the event that any vacancy is created on the Board at any time due to the removal of one or more Directors as required by Section 2.1(a)(iii)(A), then the remaining Directors shall have the right to immediately designate a replacement for each Removed Director to fill such vacancy; provided, that any such replacement shall be an Independent Director.

(i)

the number and description of New Securities proposed to be issued;

No waiver by any Party of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the Party so waiving. No waiver by any Party shall operate or be construed as a waiver in respect of any failure, breach or default not expressly identified by such written waiver, whether of a similar or different character, and whether occurring before or after that waiver. No failure to exercise, or delay in exercising, any right, remedy, power or privilege arising from this Agreement shall operate or be construed as a waiver thereof, nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. For the avoidance of doubt, nothing contained in this Section 7.8 shall diminish any of the explicit and implicit waivers described in this Agreement.

Section 7.9 Governing Law

This Agreement and all actions (whether based on contract, tort or otherwise) arising out of or relating to this Agreement or the actions of the Company or any Stockholder in the negotiation, administration, performance and enforcement thereof shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under any applicable principles of conflicts of laws thereof.

Section 7.10 Submission to Jurisdiction

In any suit, action or proceeding between the Parties arising out of or relating to this Agreement or any of the transactions contemplated hereby, each of the Parties (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware in and for New Castle County, Delaware or any federal court sitting in the State of Delaware; (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from such court; and (iii) agrees that it will not bring any such action in any

-16-

court other than the Court of Chancery for the State of Delaware in and for New Castle County, Delaware, or any federal court sitting in the State of Delaware and appellate courts thereof. Each Party irrevocably consents to the service of process outside the territorial jurisdiction of the courts referred to in this Section 7.10 in any such suit, action or proceeding by mailing copies thereof by registered or certified United States mail, postage prepaid, return receipt requested, to its address as specified in or pursuant to Section 7.2. However, the foregoing shall not limit the right of a Party to effect service of process on any other Party by any other legally available method.

Section 7.11 Waiver of Jury Trial

EACH PARTY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 7.12 Specific Enforcement

The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and (as an integral and essential part of the transactions contemplated hereby without which the parties would not have entered into this Agreement) to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in Section 7.10, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

Section 7.13 Counterparts

This Agreement may be executed in two or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered (including by electronic transmission) to the other Parties.

Section 7.14 Enforcement by Fairmount Directors

All of the Company’s rights under this Agreement may be enforced by the Fairmount Directors; provided that nothing in this Agreement shall require the Fairmount Directors to act on behalf of, or enforce any rights of, the Company. Any recovery in connection with an action brought by the Fairmount Directors hereunder shall be for the proportionate benefit of all Stockholders.

Any such request by any Demand Party pursuant to this Section 2.1(a)(i) is referred to herein as a “Demand Registration Request” and the registration so requested is referred to herein as a “Demand Registration” (with respect to any Demand Registration, the Holder(s) making such demand for registration being referred to as the “Initiating Holders”). Any Demand Registration Request may request that the Company register Registrable Securities on an appropriate form, including a shelf registration statement on Form S-3 pursuant to Rule 415 under the Securities Act and, if the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act, a “WKSI”), an automatic shelf registration statement on Form S-3. The Company shall give written notice (the “Demand Exercise Notice”) of such Demand Registration Request to each of the Holders of Registrable Securities at least five (5) Business Days prior to the filing of any registration statement under the Securities Act.

(iii) The Company shall, as expeditiously as reasonably possible, but subject to Section 2.1(b), use its commercially reasonable efforts to (x) file with the SEC (no later than sixty (60) days from the Company’s receipt of the applicable Demand Registration Request) and cause to be declared or automatically effective, as applicable, such registration under the Securities Act as soon as reasonably practicable thereafter (including, without limitation, by means of a shelf registration pursuant to Rule 415 under the Securities Act if so requested and if

the Company is then eligible to use such a registration) with respect to the Registrable Securities that the Company has been so requested to register, for distribution in accordance with the intended method of distribution, including a distribution to, and resale by, the members or partners of a Holder (a “Partner Distribution”) and (y) if requested by the Initiating Holders and to the extent applicable, obtain acceleration of the effective date of the registration statement relating to such registration.

(iv) Notwithstanding anything contained herein to the contrary, the Company shall, at the request of any Holder seeking to effect a Partner Distribution, file any prospectus supplement or post-effective amendments, or include in the initial registration statement any disclosure or language, or include in any prospectus supplement or post-effective amendment any disclosure or language, and otherwise take any action, deemed necessary or advisable by such Holder to effect such Partner Distribution.

(b) Notwithstanding anything to the contrary in Section 2.1(a), the Demand Registration rights granted in Section 2.1(a) are subject to the following limitations: (i) the Company shall not be required to (a) cause a registration pursuant to Section 2.1(a) to be declared or automatically effective, as applicable, or (b) facilitate an offering of Shares, in either case within a period of ninety (90) days after the effective date of any other registration of the Company filed pursuant to the Securities Act (other than a Form S-4 or Form S-8 or any successor or other forms promulgated for similar purposes or forms filed in connection with an exchange offer or any employee benefit or stock purchase and/or dividend reinvestment plan) or pricing date of any offering made pursuant to such registration statement; (ii) the Company shall not be required to effect more than (x) five (5) Demand Registrations on Form S-1 or any similar long-form registration at the request of the Shareholders (it being understood that if a single Demand Registration Request is delivered by more than one Shareholder, the registration requested by such Demand Registration Request shall constitute only one Demand Registration); provided, however, that the Shareholders shall each be entitled to request an unlimited number of Demand Registrations on Form S-3 or any similar short-form registration (including pursuant to Rule 415 under the Securities Act) or take-downs or other offerings off an existing Form S-3; (iii) each registration or offering in respect of a Demand Registration Request made by any Holder must include, in the aggregate, Shares having an aggregate market value of at least the lesser of (a) the Minimum Threshold (based on the Shares included in such registration by all Holders participating in such registration) and (b) the Initiating Holder’s remaining Shares; (iv) a Holder may not request that the Company file a shelf registration statement until the Company is eligible to file a registration statement on Form S-3; and (v) if a Valid Business Reason exists, then (x) the Company may postpone filing a registration statement or facilitating an offering relating to a Demand Registration Request until five (5) Business Days after such Valid Business Reason no longer exists, but in no event for more than forty-five (45) days (seventy-five (75) days in the case of a Valid Business Reason relating to the Company not having appropriate financial statements of any acquired or to be acquired entities available for filing) after the date the Valid Business Reason is initially determined to exist and (y) in case a registration statement has been filed relating to a Demand Registration Request, the Company may, to the extent a Valid Business Reason exists, suspend use of or, if required by the SEC, cause such registration statement to be withdrawn and its effectiveness terminated or may postpone amending or

supplementing such registration statement until five (5) Business Days after such Valid Business Reason no longer exists, but in no event for more than thirty (30) days after the date the Valid Business Reason is initially determined to exist (such period of postponement or withdrawal under this clause (v), the “Postponement Period”). The Company shall give written notice to the Initiating Holders and any other Holders that have requested registration pursuant to Section 2.1 or Section 2.2 of its determination to postpone or suspend use of or withdraw a registration statement and of the fact that the Valid Business Reason for such postponement or suspension or withdrawal no longer exists, in each case, promptly after the occurrence thereof; provided, however, the Company shall not be permitted to postpone or suspend use of or withdraw a registration statement after the expiration of any Postponement Period until twelve (12) months after the expiration of such Postponement Period.

If the Company shall give any notice of postponement or suspension or withdrawal of any registration statement pursuant to clause (v) above, the Company shall not, during the Postponement Period, register any Shares, other than pursuant to a registration statement on Form S-4 or S-8 (or an equivalent registration form then in effect). Each Holder of Registrable Securities agrees that, upon receipt of any notice from the Company that the Company has determined to suspend use of, withdraw, terminate or postpone amending or supplementing any registration statement pursuant to clause (v) above, such Holder will discontinue its disposition of Registrable Securities pursuant to such registration statement. If the Company shall have suspended use of, withdrawn or terminated a registration statement filed under Section 2.1(a)(i) (whether pursuant to clause (v) above or as a result of any stop order, injunction or other order or requirement of the SEC or any other governmental agency or court), the Company shall not be considered to have effected a Demand Registration for the purposes of this Agreement until the Company shall have permitted use of such suspended registration statement or filed a new registration statement covering the Registrable Securities covered by the withdrawn or terminated registration statement and such registration statement shall have been declared effective and shall not have been withdrawn. If the Company shall give any notice of suspension, withdrawal or postponement of a registration statement, the Company shall, not later than five (5) Business Days after the Valid Business Reason that caused such suspension, withdrawal or postponement no longer exists (but in no event later than thirty (30) days after the date of the suspension, postponement or withdrawal), as applicable, permit use of such suspended registration statement or use its commercially reasonable efforts to effect the registration under the Securities Act of the Registrable Securities covered by the withdrawn or postponed registration statement in accordance with this Section 2.1 (unless the Initiating Holders shall have withdrawn such request, in which case the Company shall not be considered to have effected a Demand Registration for the purposes of this Agreement and such request shall not count as a Demand Registration Request under this Agreement), and following such permission or such effectiveness such registration shall no longer be deemed to be suspended, withdrawn or postponed pursuant to clause (v) of Section 2.1(b) above.

(c) In connection with any Demand Registration (including any Shelf Underwriting or Underwritten Block Trade (as defined below)), the Holders of a majority of the Registrable Securities included in such Demand Registration shall have the right to designate the lead managing underwriter (any lead managing underwriter for the purposes of this Agreement, the

“Manager”) in connection with any underwritten offering pursuant to such registration and each other managing underwriter for any such underwritten offering and counsel for the Participating Shareholders; provided that in each case, each such underwriter is reasonably satisfactory to the Company, which approval shall not be unreasonably withheld or delayed.

(d) No Demand Registration shall be deemed to have occurred for purposes of Section 2.1(a) (i) if the registration statement relating thereto (x) does not become effective, (y) is not maintained effective for a period of at least one hundred eighty (180) days after the effective date thereof or such shorter period during which all Registrable Securities included in such registration statement have actually been sold (provided, however, that such period shall be extended for a period of time equal to the period the Holder of Registrable Securities refrains from selling any securities included in such registration statement at the request of the Company or an underwriter of the Company), or (z) is subject to a stop order, injunction, or similar order or requirement of the SEC during such period, (ii) if any of the Registrable Securities requested by such Initiating Holder to be included in such Demand Registration are not so included pursuant to Section 2.3 (even where some or most of such Holder’s Registrable Securities are included in such Demand Registration), (iii) if the method of disposition is a firm commitment underwritten public offering and any of the applicable Registrable Securities identified in the preliminary prospectus or preliminary prospectus supplement, as applicable, for such offering as being sold by the Participating Holders have not been sold pursuant thereto (other than as a result of a default or breach thereunder by such Initiating Holder(s)) or (iv) if the conditions to closing specified in any underwriting agreement, purchase agreement or similar agreement entered into in connection with the registration relating to such request are not satisfied (other than as a result of a default or breach thereunder by such Initiating Holder(s)) or are otherwise not waived by such Initiating Holder(s).

(e) In the event that the Company files a shelf registration statement under Rule 415 of the Securities Act pursuant to a Demand Registration Request and such registration becomes effective (such registration statement, a “Shelf Registration Statement”), the Initiating Holders with respect to such Demand Registration Request and the other Demand Parties with Registrable Securities registered on such Shelf Registration Statement (or, in the case of an automatic shelf registration statement, the Demand Parties) shall have the right at any time or from time to time to elect to sell pursuant to an underwritten offering Registrable Securities available for sale pursuant to such registration statement. Any such Initiating Holder or Demand Party shall make such election by delivering to the Company a written request (a “Shelf Underwriting Request”) for such underwritten offering specifying the number of Registrable Securities that such Initiating Holder or Demand Party, as applicable, desires to sell pursuant to such underwritten offering (the “Shelf Underwriting”). As promptly as practicable, but no later than two (2) Business Days after receipt of a Shelf Underwriting Request, the Company shall give written notice (the “Shelf Underwriting Notice”) of such Shelf Underwriting Request to the Holders of other Registrable Securities registered on such Shelf Registration Statement (“Shelf Registrable Securities”). The Company, subject to Sections 2.3 and 2.6, shall include in such Shelf Underwriting (x) the Registrable Securities of the Initiating Holders and (y) the Shelf Registrable Securities of any other Holder of Shelf Registrable Securities that shall have made a written request to the Company for inclusion in such Shelf Underwriting (which request shall

specify the maximum number of Shelf Registrable Securities intended to be disposed of by such Holder) within five (5) days after the receipt of the Shelf Underwriting Notice. The Company shall, as expeditiously as possible (and in any event within twenty (20) days after the receipt of a Shelf Underwriting Request), but subject to Section 2.1(b), use its commercially reasonable efforts to facilitate such Shelf Underwriting. Notwithstanding the foregoing, but subject to Section 2.1(b), if a Demand Party wishes to engage in an underwritten block trade or similar transaction or other transaction with a 2-day or less marketing period (collectively, “Underwritten Block Trade”) pursuant to a Shelf Registration Statement (either through filing an automatic shelf registration statement or through a take-down from an already effective Shelf Registration Statement), then notwithstanding the foregoing time periods, such Demand Party only needs to notify the Company of the Underwritten Block Trade two (2) Business Days prior to the day such Underwritten Block Trade is to commence, and the Company shall notify the other Holders (the “Company Block Trade Notice”) on the same day, and such other Holders must elect whether or not to participate by the next Business Day (i.e., one (1) Business Day prior to the date such offering is to commence). The Company shall as expeditiously as possible, but subject to Section 2.1(b), use its commercially reasonable efforts to facilitate such Underwritten Block Trade (which may close as early as two (2) Business Days after the date it commences); provided, however, that the Demand Party requesting such Underwritten Block Trade shall use commercially reasonable efforts to work with the Company and the underwriters prior to making such request in order to facilitate preparation of the registration statement (including filing an automatic shelf registration statement), prospectus and other offering documentation related to the Underwritten Block Trade. In the event a Demand Party requests such an Underwritten Block Trade, notwithstanding anything to the contrary in this Section 2.1 or in Section 2.2, any holder of Shares who is not a Holder shall have no right to notice of or to participate in such Underwritten Block Trade at any time. The Company shall, at the request of any Initiating Holder, file any prospectus supplement or, if the applicable Shelf Registration Statement is an automatic shelf registration statement, any post-effective amendments and otherwise take any action necessary to include therein all disclosure and language deemed necessary or advisable by the Initiating Holders or any other Holder of Shelf Registrable Securities to effect such Shelf Underwriting. Once a Shelf Registration Statement has been declared effective, the Demand Parties may request, and the Company shall be required to facilitate, subject to Section 2.1(b), an unlimited number of Shelf Underwritings with respect to such Shelf Registration Statement. Notwithstanding anything to the contrary in this Section 2.1(e), each Shelf Underwriting must include, in the aggregate, Shares having an aggregate market value of at least the lesser of (a) the Minimum Threshold (based on the Shares included in such Shelf Underwriting by all Holders participating in such Shelf Underwriting) and (b) the Initiating Holder’s remaining Shares.

(f) Any Initiating Holder may revoke a Demand Registration Request delivered by such Initiating Holder at any time prior to the effectiveness of such Demand Registration and such Demand Registration shall have no further force or effect and such request shall not count as a Demand Registration Request under this Agreement.

(g) In the event that any Holder fails to take all steps necessary to commence an Underwritten Block Trade within two (2) Business Days of the date on which a Company Block

Trade Notice is sent to such Holder, then, notwithstanding anything to the contrary in Sections 2.1 and 2.2, the Demand Party requesting the Underwritten Block Trade shall have the right to exclude such Holder from participating in such Underwritten Block Trade.

2.2. Piggyback Registrations.

(a) If the Company proposes or is required (pursuant to Section 2.1 or otherwise) to register any Shares for its own account or for the account of any other shareholder under the Securities Act (other than a Form S-4 or Form S-8 or any successor or other forms promulgated for similar purposes or forms filed in connection with an exchange offer or any employee benefit or stock purchase and/or dividend reinvestment plan or a registration statement registering Shares that are issuable solely upon conversion of Share Equivalents), the Company shall give written notice (the “Piggyback Notice”) of its intention to do so to each of the Holders of Registrable Securities at least five (5) Business Days prior to the filing of any registration statement under the Securities Act. Upon the written request of any such Holder, made within five (5) days following the receipt of any such Piggyback Notice (which request shall specify the maximum number of Registrable Securities intended to be disposed of by such Holder and the intended method of distribution thereof), the Company shall, subject to Sections 2.2(c), 2.2(f), 2.3 and 2.6 hereof, use its commercially reasonable efforts to cause all such Registrable Securities, the Holders of which have so requested the registration thereof, to be registered under the Securities Act with the securities that the Company at the time proposes to register to permit the sale or other disposition by the Holders (in accordance with the intended method of distribution thereof) of the Registrable Securities to be so registered, including, if necessary, by filing with the SEC a post-effective amendment or a supplement to the registration statement filed by the Company or the prospectus related thereto. There is no limitation on the number of such piggyback registrations pursuant to the preceding sentence that the Company is obligated to effect. No registration of Registrable Securities effected under this Section 2.2(a) shall relieve the Company of its obligations to effect Demand Registrations under Section 2.1 hereof. If the Company proposes or is required (pursuant to Section 2.1 or otherwise) to sell pursuant to an underwritten offering Registrable Securities available for sale pursuant to a Shelf Registration Statement (a “Company Shelf Underwriting”), the Company shall, as promptly as practicable, give written notice of such Company Shelf Underwriting (a “Company Shelf Notice”) to each Holder of Shelf Registrable Securities. In addition to any equity securities that the Company proposes to sell for its own account in such Company Shelf Underwriting, the Company shall, subject to Sections 2.3 and 2.6, include in such Company Shelf Underwriting the Shelf Registrable Securities of any other Holder of Shelf Registrable Securities that shall have made a written request to the Company for inclusion in such Company Shelf Underwriting (which request shall specify the maximum number of Shelf Registrable Securities intended to be disposed of by such Holder) within five (5) Business Days after the receipt of the Company Shelf Notice. Notwithstanding the foregoing, (x) if the Company wishes to engage in an Underwritten Block Trade pursuant to a Shelf Registration Statement (a “Company Underwritten Block Trade”), then notwithstanding the foregoing time periods, the Company only needs to notify the Holders of the Company Underwritten Block Trade two (2) Business Days prior to the day such Company Underwritten Block Trade is to commence and the Company shall notify the Holders and such Holders must elect whether or not to participate by the next Business Day (i.e., one (1)

Business Day prior to the date such Underwritten Block Trade is to commence), and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such Company Underwritten Block Trade (which may close as early as two (2) Business Days after the date it commences), and (y) if a Demand Party wishes to engage in an Underwritten Block Trade pursuant to a Shelf Registration Statement, then the provisions set forth in Section 2.1(e) shall apply to such Underwritten Block Trade. In the event the Company or a Demand Party requests a Company Underwritten Block Trade or an Underwritten Block Trade, as applicable, notwithstanding anything to the contrary in Section 2.1 or in this Section 2.2, any holder of Shares who does not constitute a Holder shall have no right to notice of or to participate in such Company Underwritten Block Trade or Underwritten Block Trade, as applicable.

(b) The Company, subject to Sections 2.3 and 2.6 and the final sentence of Section 2.2(a), may elect to include in any registration statement and offering pursuant to demand registration rights by any Person or otherwise, (i) authorized but unissued Shares or Shares held by the Company as treasury shares and (ii) any other Shares that are requested to be included in such registration pursuant to the exercise of piggyback registration rights granted by the Company after the date hereof and that are not inconsistent with the rights granted in, or otherwise conflict with the terms of, this Agreement (“Additional Piggyback Rights”); provided, however, that, with respect to any underwritten offering, including a block trade, such inclusion shall be permitted only to the extent that it is pursuant to, and subject to, the terms of the underwriting agreement or arrangements, if any, entered into by the Initiating Holders or the Majority Participating Holders in such underwritten offering.

(c) If, at any time after giving a Piggyback Notice and prior to the effective date of the registration statement filed in connection with such registration, (i) any Initiating Holder determines for any reason not to proceed with the proposed registration, the Company may at its election give written notice of such determination to each Holder of record of Registrable Securities and thereupon will be relieved of its obligation to register any Registrable Securities in connection with such registration and (ii) other than in connection with a Demand Registration, the Company shall determine for any reason not to register or to delay registration of such equity securities, the Company may, at its election, give written notice of such determination to all Holders of record of Registrable Securities and (x) in the case of a determination not to register, shall be relieved of its obligation to register any Registrable Securities in connection with such abandoned registration, without prejudice, however, to the rights of Holders under Section 2.1, and (y) in the case of a determination to delay such registration of its equity securities, shall be permitted to delay the registration of such Registrable Securities for the same period as the delay in registering such other equity securities.

(d) Any Holder shall have the right to withdraw its request for inclusion of its Registrable Securities in any registration statement pursuant to this Section 2.2 by giving written notice to the Company of its request to withdraw; provided, however, that such request must be made in writing prior to the earlier of the execution of the underwriting agreement or the execution of the custody agreement with respect to such registration or as otherwise required by the underwriters.

(e) Notwithstanding anything contained herein to the contrary, the piggyback registration rights granted pursuant to this Section 2.2 shall automatically terminate at such time as both (i) the Registrable Securities beneficially owned by the Shareholders no longer constitute at least five percent (5%) of the outstanding Shares and (ii) no Shareholder is an “affiliate” of the Company (within the meaning of Rule 144).

2.3. Allocation of Securities Included in Registration Statement.

(a) If any requested registration made pursuant to Section 2.1 (including a Shelf Underwriting) involves (x) an underwritten offering and the Manager of such offering shall advise the Company and any Holder of Registrable Securities included in such underwritten offering that, in its view, the number of securities requested to be included in such underwritten offering by the Holders of Registrable Securities, the Company or any other Persons exercising Additional Piggyback Rights exceeds the largest number (the “Section 2.3(a)(x) Sale Number”) that can be sold in an orderly manner in such underwritten offering within a price range acceptable to the Initiating Holders and the Majority Participating Holders, or (y) an Underwritten Block Trade and the number of securities requested to be included in such Underwritten Block Trade by the Holders of Registrable Securities or any other Persons exceeds the number that are sold in any such Underwritten Block Trade (the “Section 2.3(a) Block Trade Sale Number” and, together with the Section 2.3(a)(x) Sale Number, the “Section 2.3(a) Sale Number”), the Company shall use its commercially reasonable efforts to include in such underwritten offering:

(i) first, all Registrable Securities requested to be included in such underwritten offering by the Holders thereof (including pursuant to the exercise of piggyback rights pursuant to Section 2.2(a)); provided, however, that if the number of such Registrable Securities exceeds the Section 2.3(a) Sale Number, the number of such Registrable Securities (not to exceed the Section 2.3(a) Sale Number) to be included in such underwritten offering shall be allocated on a pro rata basis among all Holders requesting that Registrable Securities be included in such underwritten offering (including pursuant to the exercise of piggyback rights pursuant to Section 2.2(a)), based on the number of Registrable Securities then owned by each such Holder requesting inclusion in relation to the aggregate number of Registrable Securities owned by all Holders requesting inclusion;

(ii) second, to the extent that the number of Registrable Securities to be included pursuant to clause (i) of this Section 2.3(a) is less than the Section 2.3(a) Sale Number, any securities that the Company proposes to register or sell, up to the Section 2.3(a) Sale Number; and

(iii) third, to the extent that the number of Registrable Securities to be included pursuant to clauses (i) and (ii) of this Section 2.3(a) is less than the Section 2.3(a) Sale Number, the remaining securities to be included in such underwritten offering shall be allocated on a pro rata basis among all Persons requesting that securities be included in such underwritten offering pursuant to the exercise of Additional Piggyback Rights (“Additional Piggyback Shares”), based on the number of Additional Piggyback Shares then owned by each Person requesting inclusion in relation to the aggregate number of Additional Piggyback Shares owned by all Persons requesting inclusion, up to the Section 2.3(a) Sale Number.

(b) If any registration or offering made pursuant to Section 2.2 involves (x) an underwritten primary offering on behalf of the Company after the date hereof and the Manager shall advise the Company that, in its view, the number of securities requested to be included in such underwritten offering by the Holders of Registrable Securities, the Company or any other Persons exercising Additional Piggyback Rights exceeds the largest number (the “Section 2.3(b)(x) Sale Number”) that can be sold in an orderly manner in such underwritten offering within a price range acceptable to the Company or (y) a Company Underwritten Block Trade and the number of securities requested to be included in such Company Underwritten Block Trade by the Company, the Holders of Registrable Securities or any other Persons exceeds the number that are sold in any such Company Underwritten Block Trade (the “Section 2.3(b) Block Trade Sale Number” and, together with the Section 2.3(b)(x) Sale Number, the “Section 2.3(b) Sale Number”), the Company shall use its commercially reasonable efforts to include in such underwritten offering:

(i) first, all equity securities that the Company proposes to register or sell for its own account;

(ii) second, to the extent that the number of Registrable Securities to be included pursuant to clause (i) of this Section 2.3(b) is less than the Section 2.3(b) Sale Number, the remaining Registrable Securities to be included in such underwritten offering shall be allocated on a pro rata basis among all Holders requesting that Registrable Securities be included in such underwritten offering pursuant to the exercise of piggyback rights pursuant to Section 2.2(a), based on the number of Registrable Securities then owned by each such Holder requesting inclusion in relation to the aggregate number of Registrable Securities owned by all Holders requesting inclusion, up to the Section 2.3(b) Sale Number; and

(iii) third, to the extent that the number of Registrable Securities to be included pursuant to clauses (i) and (ii) of this Section 2.3(b) is less than the Section 2.3(b) Sale Number, the remaining securities to be included in such underwritten offering shall be allocated on a pro rata basis among all Persons requesting that securities be included in such underwritten offering pursuant to the exercise of Additional Piggyback Rights, based on the number of Additional Piggyback Shares then owned by each Person requesting inclusion in relation to the aggregate number of Additional Piggyback Shares owned by all Persons requesting inclusion, up to the Section 2.3(b) Sale Number.

(c) If any registration pursuant to Section 2.2 involves an underwritten offering that was initially requested by any Person(s) (other than a Holder) to whom the Company has granted registration rights that are not inconsistent with the rights granted in, and do not otherwise conflict with the terms of, this Agreement and the Manager shall advise the Company that, in its view, the number of securities requested to be included in such underwritten offering exceeds the number (the “Section 2.3(c) Sale Number”) that can be sold in an orderly manner in such underwritten offering within a price range acceptable to the Company, the Company shall include in such underwritten offering:

(i) first, the securities requested to be included in such underwritten offering shall be allocated on a pro rata basis among such Person(s) requesting the registration and all Holders requesting that Registrable Securities be included in such underwritten offering pursuant to the exercise of piggyback rights pursuant to Section 2.2(a), based on the aggregate number of securities or Registrable Securities, as applicable, then owned by each of the foregoing requesting inclusion in relation to the aggregate number of securities or Registrable Securities, as applicable, owned by all such Holders and Persons requesting inclusion, up to the Section 2.3(c) Sale Number;

(ii) second, to the extent that the number of Registrable Securities and securities to be included pursuant to clause (i) of this Section 2.3(c) is less than the Section 2.3(c) Sale Number, the remaining securities to be included in such underwritten offering shall be allocated on a pro rata basis among all Persons requesting that securities be included in such underwritten offering pursuant to the exercise of Additional Piggyback Rights, based on the number of Additional Piggyback Shares then owned by each Person requesting inclusion in relation to the aggregate number of Additional Piggyback Shares owned by all Persons requesting inclusion, up to the Section 2.3(c) Sale Number; and

(iii) third, to the extent that the number of Registrable Securities and securities to be included pursuant to clauses (i) and (ii) of this Section 2.3(c) is less than the Section 2.3(c) Sale Number, the remaining securities to be included in such underwritten offering shall be allocated to shares the Company proposes to register or sell for its own account, up to the Section 2.3(c) Sale Number.

(d) If, as a result of the proration provisions set forth in clauses (a), (b) or (c) of this Section 2.3, any Holder shall not be entitled to include all Registrable Securities in an underwritten offering that such Holder has requested be included, such Holder may elect to withdraw such Holder’s request to include Registrable Securities in the registration to which such underwritten offering relates or may reduce the number requested to be included; provided, however, that (x) such request must be made in writing prior to the earlier of the execution of the underwriting agreement or the execution of the custody agreement with respect to such registration and (y) such withdrawal or reduction shall be irrevocable and, after making such withdrawal or reduction, such Holder shall no longer have any right to include Registrable Securities in the registration as to which such withdrawal or reduction was made to the extent of the Registrable Securities so withdrawn or reduced. If more than one of the Shareholders desires to register or sell Shares and the number of Shares to be sold by the Shareholders collectively is to be reduced for any reason pursuant to Section 2.3 or otherwise, than the Shareholders may allocate among themselves the number of Shares each may register or sell (but capped at the maximum amount of Shares they are permitted collectively to sell in such registration or offering).

2.4. Registration Procedures. If and whenever the Company is required by the provisions of this Agreement to effect or cause the registration of and/or participate in any offering or sale of any Registrable Securities under the Securities Act as provided in this Agreement (or use commercially reasonable efforts to accomplish the same), the Company shall, as expeditiously as reasonably possible:

(a) prepare and file all filings with the SEC and FINRA required for the consummation of the offering, including preparing and filing with the SEC a registration statement on an appropriate registration form of the SEC for the disposition of such Registrable Securities in accordance with the intended method of disposition thereof (including, without limitation, a Partner Distribution), which registration form (i) shall be selected by the Company (except as provided for in a Demand Registration Request) and (ii) shall, in the case of a shelf registration, be available for the sale of the Registrable Securities by the selling Holders thereof and such registration statement shall comply as to form in all material respects with the requirements of the applicable registration form and include all financial statements required by the SEC to be filed therewith, and the Company shall use its commercially reasonable efforts to cause such registration statement to become effective and remain continuously effective for such period as any Participating Holder pursuant to such registration statement shall reasonably request (provided, however, that as far in advance as reasonably practicable before filing a registration statement or prospectus or any amendments or supplements thereto (other than any amendment by means of a document filed by the Company under the Exchange Act) or any free writing prospectus related thereto, the Company will furnish to the Demand Parties, counsel for each of the Participating Holders and counsel for the Manager, if any, copies of reasonably complete drafts of all such documents proposed to be filed (including all exhibits thereto and each document incorporated by reference therein to the extent then required by the rules and regulations of the SEC), which documents will be subject to the reasonable review and reasonable comment of such counsel (including any objections to any information pertaining to any Participating Holder and its plan of distribution and otherwise to the extent necessary, if at all, to complete the filing or maintain the effectiveness thereof), and the Company shall make the changes reasonably requested by such counsel and shall not file any registration statement or amendment thereto (other than any amendment by means of a document filed by the Company under the Exchange Act), any prospectus or supplement thereto or any free writing prospectus related thereto to which counsel for the Participating Holders, the Majority Participating Holders or the underwriters, if any, shall reasonably object); provided, however, that, notwithstanding the foregoing, in no event shall the Company be required to file any document with the SEC that in the view of the Company or its counsel contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make any statement therein not misleading; provided, further, that any Participating Holder shall be entitled to review and provide reasonable comment on disclosure regarding itself included or proposed to be included in any such filing;

(d) use its commercially reasonable efforts to register or qualify the Registrable Securities covered by such registration statement under such other securities or state “blue sky” laws of such jurisdictions as any sellers of Registrable Securities or any managing underwriter, if any, shall reasonably request in writing, and do any and all other acts and things that may be reasonably necessary or advisable to enable such sellers or underwriter, if any, to consummate the disposition of the Registrable Securities in such jurisdictions in accordance with the intended methods of disposition (including keeping such registration or qualification in effect for so long as such registration statement remains in effect), except that in no event shall the Company be required to qualify to do business as a foreign corporation in any jurisdiction where it would not, but for the requirements of this paragraph (d), be required to be so qualified, to subject itself to taxation in any such jurisdiction or to consent to general service of process in any such jurisdiction;

(e) promptly notify each Participating Holder and each managing underwriter, if any: (i) when the registration statement, any pre-effective amendment, the prospectus or any prospectus supplement related thereto, any post-effective amendment to the registration statement or any free writing prospectus has been filed with the SEC and, with respect to the registration statement or any post-effective amendment, when the same has become effective; (ii) of any request by the SEC or state securities authority for amendments or supplements to the registration statement or the prospectus related thereto or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the registration statement

(f) comply (and continue to comply) in all material respects with all applicable rules and regulations of the SEC, and make generally available to its security holders, as soon as reasonably practicable after the effective date of the registration statement (and in any event within forty-five (45) days, or ninety (90) days if it is a fiscal year, after the end of such twelve month period described hereafter), an earnings statement (which need not be audited) covering the period of at least twelve (12) consecutive months beginning with the first day of the Company’s first calendar quarter after the effective date of the registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

(i) in connection with any underwritten offering, use its commercially reasonable efforts to make available at reasonable times upon reasonable request its senior management and other employees for participation in “road shows” and other marketing efforts and otherwise provide reasonable assistance to the underwriters (taking into account the Company’s reasonable business needs and the requirements of the marketing process) in the marketing of Registrable Securities;

(l) in connection with any underwritten offering, use its commercially reasonable efforts (i) to obtain opinions from the Company’s counsel, including local counsel, and a “cold comfort” letter, updates thereof and consents from the independent public accountants who have certified the financial statements of the Company (and/or any other financial statements) included or incorporated by reference in the applicable registration statement, in each case, in customary form and covering such matters as are customarily covered by such opinions and “cold comfort” letters (including, in the case of such “cold comfort” letter, events subsequent to the date of such financial statements) delivered to underwriters in underwritten public offerings, which opinions and letters shall be dated the dates such opinions and “cold comfort” letters are customarily dated and otherwise reasonably satisfactory to the underwriters, (ii) to obtain customary letters from the Company’s reserve valuation experts addressed to the underwriters and (iii) to furnish to each Participating Holder upon its request and to each underwriter, if any, copies of such opinions and letters addressed to such underwriter;

To the extent the Company is a WKSI at the time any Demand Registration Request is submitted to the Company, and such Demand Registration Request requests that the Company file an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “automatic shelf registration statement”) on Form S-3, the Company shall file an automatic shelf registration statement that covers those Registrable Securities that are requested to be registered. To the extent the Company has filed an automatic shelf registration statement, the Company shall use its commercially reasonable efforts to remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such automatic shelf registration statement is required to remain effective. If the Company is requested to register Registrable Securities on an automatic shelf registration statement, the Company shall pay the applicable filing fee related to such Registrable Securities at the time of filing of the automatic shelf registration statement. If the automatic shelf registration statement has been outstanding for at least three (3) years, at or prior to the end of the third year the Company shall, upon request, refile a new automatic shelf registration statement covering the Registrable Securities that remain outstanding. If at any time when the Company is required to re-evaluate its WKSI status the Company determines that it is not a WKSI, the Company shall use its commercially reasonable efforts to refile the shelf registration statement on Form S-3 and, if such form is not available, Form S-1 and keep such registration statement effective during the period during which such registration statement is required to be kept effective.

If the Company files any shelf registration statement for the benefit of the holders of any of its securities other than the Holders, and the Holders do not request that their Registrable Securities be included in such Shelf Registration Statement, the Company agrees that it shall include in such registration statement such disclosures as may be required by Rule 430B under the Securities Act (referring to the unnamed selling security holders in a generic manner by identifying the initial offering of the securities to the Holders) in order to ensure that the Holders may be added to such shelf registration statement at a later time through the filing of a prospectus supplement rather than a post-effective amendment.

The Company may require as a condition to the Company’s obligations under this Section 2.4 that each Participating Holder as to which any registration is being effected (i) furnish the Company such information regarding such seller and the distribution of such securities as the Company may from time to time reasonably request, provided that such information is necessary for the Company to consummate such registration and shall be used only in connection with such registration and (ii) provide any underwriters participating in the distribution of such securities such information as the underwriters may request and execute and deliver any agreements, certificates or other documents as the underwriters may request.

Each Holder of Registrable Securities agrees that upon receipt of any notice from the Company of the happening of any event of the kind described in clause (v) of paragraph (e) of this Section 2.4, such Holder will discontinue such Holder’s disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by paragraph (e) of this Section 2.4 and, if so directed by the Company, will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies, then in such Holder’s possession of the prospectus covering such Registrable Securities that was in effect at the time of receipt of such notice. In the event the Company shall give any such notice, the applicable period mentioned in paragraph (b) of this Section 2.4 shall be extended by the number of days during such period from and including the date of the giving of such notice to and including the date when each Participating Holder covered by such registration statement shall have received the copies of the supplemented or amended prospectus contemplated by paragraph (e) of this Section 2.4. The period(s) during which the Holders are required to discontinue disposition of securities pursuant to this paragraph shall not exceed forty-five (45) days with respect to any one such period within any 365 day period (either alone or in combination with a Postponement Period pursuant to Section 2.1(b) hereof).

To the extent that any Holder is or may be deemed to be an “underwriter” of Registrable Securities pursuant to any SEC comments or policies, the Company agrees that such Holder shall be entitled to conduct the due diligence that an underwriter would normally conduct in connection with an offering of securities registered under the Securities Act, including without limitation receipt of customary opinions and comfort letters addressed to such Holder (to the extent permitted by applicable accounting or auditing guidance).

2.5. Registration Expenses.

(a) The Company shall pay all Expenses with respect to any registration or offering of Registrable Securities pursuant to Section 2, whether or not a registration statement becomes effective or the offering is consummated.

(b) Notwithstanding the foregoing, (x) the provisions of this Section 2.5 shall be deemed amended to the extent necessary to cause these expense provisions to comply with state “blue sky” laws of each state in which the offering is made, and (y) in connection with any underwritten offering hereunder, each Participating Holder shall pay all underwriting discounts and commissions and any transfer taxes, if any, attributable to the sale of such Registrable Securities, pro rata with respect to payments of discounts and commissions in accordance with the number of Shares sold in the offering by such Holder. In addition, each Participating Holder shall pay the expenses of its own counsel and advisors, except to the extent provided in the definition of “Expenses”.

2.6. Certain Limitations on Registration Rights. In the case of any registration under Section 2.1 involving an underwritten offering, or, in the case of a registration under Section 2.2, if the Company has determined to enter into an underwriting agreement in connection therewith, all securities to be included in such underwritten offering shall be subject to such underwriting agreement and no Person may participate in such underwritten offering unless such Person (i) agrees to sell such Person’s securities on the basis provided therein and completes and executes all reasonable questionnaires and other documents (including custody agreements and powers of attorney, if any) that must be executed in connection therewith; provided, however, that all such documents shall be consistent with the provisions hereof and (ii) provides such other information to the Company or the underwriter as may be necessary to register such Person’s securities.

2.7. Limitations on Sale or Distribution of Other Securities.

(a) Each Holder agrees (whether or not such Holder can participate in any such offering), (i) to the extent requested by a managing underwriter, if any, of any underwritten public offering pursuant to a registration or offering effected pursuant to Section 2.1 (including any Shelf Underwriting pursuant to Section 2.1(e)), not to sell, transfer or otherwise dispose of, including any sale pursuant to Rule 144, any Shares or Share Equivalents (other than as part of such underwritten public offering) during the time period reasonably requested by the managing underwriter, not to exceed ninety (90) days from the pricing date of such offering or such shorter period as the managing underwriter, the Company or any executive officer or director of the Company shall agree to (and the Company hereby also so agrees (except that the Company may effect any sale or distribution of any such securities pursuant to a registration on Form S-4 or Form S-8 or any successor or other forms promulgated for similar purposes or forms filed in connection with an exchange offer or any employee benefit or stock purchase and/or dividend reinvestment plan), to use its commercially reasonable efforts to cause all directors and executive officers of the Company, to so agree), and (ii) to the extent requested by a managing underwriter of any underwritten public offering effected by the Company for its own account (including without limitation any offering in which one or more Holders is selling Shares pursuant to the

exercise of piggyback rights under Section 2.2 hereof), not to sell, transfer or otherwise dispose of, including any sale pursuant to Rule 144, any Shares or Share Equivalents (other than as part of such underwritten public offering) during the time period reasonably requested by the managing underwriter, which period shall not exceed ninety (90) days from the pricing date of such offering or such shorter period as the managing underwriter, the Company or any executive officer or director of the Company shall agree to. Each Holder agrees to execute and deliver customary lock-up agreements for the benefit of the underwriters with such form and substance as the managing underwriter shall reasonably determine.

(b) The Company hereby agrees that, in connection with an offering pursuant to Section 2.1 (including any Shelf Underwriting pursuant to Section 2.1(e)) or Section 2.2, the Company shall not sell, transfer, or otherwise dispose of, any Shares or Share Equivalents (other than as part of such underwritten public offering, a registration on Form S-4 or Form S-8 or any successor or other forms promulgated for similar purposes or forms filed in connection with an exchange offer or any employee benefit or stock purchase and/or dividend reinvestment plan), until a period of ninety (90) days (or such shorter period to which the Majority Participating Holders shall agree) shall have elapsed from the pricing date of such offering, except to the extent otherwise agreed to by the underwriters as provided in any lock-up agreement required in connection with such offering; and the Company shall (i) so provide in any registration rights agreements hereafter entered into with respect to any of its securities and (ii) use its commercially reasonable efforts to cause all directors and executive officers of the Company to so agree.

2.8. No Required Sale. Nothing in this Agreement shall be deemed to create an independent obligation on the part of any Holder to sell any Registrable Securities pursuant to any effective registration statement. A Holder is not required to include any of its Registrable Securities in any registration statement, is not required to sell any of its Registrable Securities that are included in any effective registration statement, may sell any of its Registrable Securities in any manner in compliance with applicable law (including pursuant to Rule 144) even if such shares are already included on an effective registration statement, and may request that Registrable Securities be registered or sold pursuant to a registration statement even if such Shares are eligible to be sold pursuant to Rule 144.

2.9. Indemnification.

(a) In the event of any registration or offer and sale of any securities of the Company under the Securities Act pursuant to this Section 2, the Company will (without limitation as to time), and hereby agrees to, and hereby does, indemnify and hold harmless, to the fullest extent permitted by law, each Participating Holder, its directors, officers, fiduciaries, employees, stockholders, members, general and limited partners, affiliates, successors and assigns (and the directors, officers, fiduciaries, employees, stockholders, members, general and limited partners, affiliates, successors and assigns thereof), and each other Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any such Participating Holder and each director, officer, employee, stockholder, fiduciary, managing director, affiliate, successor, assign or partner of such controlling Person (and all controlling

Persons of any such Persons or other controlling Persons), from and against any and all losses, claims, damages or liabilities, joint or several, actions or proceedings (whether commenced or threatened) and expenses (including reasonable fees of counsel and any amounts paid in any settlement effected with the Company’s consent, which consent shall not be unreasonably withheld or delayed) to which each such indemnified party may become subject under the Securities Act or otherwise in respect thereof (collectively, “Claims”), insofar as such Claims arise out of, are based upon, relate to or are in connection with (i) any untrue statement or alleged untrue statement of a material fact contained in any registration statement under which such securities were registered under the Securities Act or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary, final or summary prospectus or any amendment or supplement thereto, together with the documents incorporated by reference therein, or any free writing prospectus utilized in connection therewith, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or (iii) any violation by the Company of any federal, state or common law rule or regulation applicable to the Company and relating to any action required of or inaction by the Company in connection with any such offering of Registrable Securities, and the Company will reimburse any such indemnified party for any documented legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim as such expenses are incurred; provided, however, that the Company shall not be liable to any such indemnified party in any such case to the extent such Claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact or omission or alleged omission of a material fact made in such registration statement or amendment thereof or supplement thereto or in any such prospectus or any preliminary, final or summary prospectus or free writing prospectus in reliance upon and in strict conformity with written information furnished to the Company by or on behalf of such indemnified party specifically for use therein. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such seller.

(b) Each Participating Holder shall, severally and not jointly, indemnify and hold harmless (in the same manner and to the same extent as set forth in paragraph (a) of this Section 2.9) to the extent permitted by law the Company, its officers who signed the applicable registration statement and its directors, each Person controlling the Company within the meaning of the Securities Act and each director, officer, employee, stockholder, fiduciary, managing director, affiliate, successor, assign or partner of such controlling Person (and all controlling Persons of any such Persons or other controlling Persons) with respect to any untrue statement or alleged untrue statement of any material fact in, or omission or alleged omission of any material fact from, such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, or any free writing prospectus utilized in connection therewith, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in strict conformity with written information furnished to the Company or its representatives by or on behalf of such Participating Holder specifically for use therein, and each such Participating Holder, shall reimburse such indemnified party for any legal

or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim as such expenses are incurred; provided, however, that the aggregate amount that any such Participating Holder shall be required to pay pursuant to this Section 2.9 (including pursuant to indemnity, contribution or otherwise) shall in no case be greater than the amount of the net proceeds actually received by such Participating Holder upon the sale of the Registrable Securities pursuant to the registration statement giving rise to such Claim; provided, further, that such Participating Holder shall not be liable in any such case to the extent that prior to the filing of any such registration statement or prospectus or amendment thereof or supplement thereto, or any free writing prospectus utilized in connection therewith, such Participating Holder has furnished in writing to the Company information expressly for use in such registration statement or prospectus or any amendment thereof or supplement thereto or free writing prospectus which corrected or made not misleading information previously furnished to the Company. The Company and each Participating Holder hereby acknowledge and agree that, unless otherwise expressly agreed to in writing by such Participating Holders to the contrary, for all purposes of this Agreement, the only information furnished or to be furnished to the Company for use in any such registration statement, preliminary, final or summary prospectus or amendment or supplement thereto, or any free writing prospectus, are statements specifically relating to (i) the beneficial ownership of Shares by such Participating Holder and its Affiliates as disclosed in the section of such document entitled “Selling Shareholders” or “Principal and Selling Shareholders” or other variations thereof and (ii) the name and address of such Participating Holder. If any additional information about such Holder or the plan of distribution (other than for an underwritten offering) is required by law to be disclosed in any such document, then such Holder shall not unreasonably withhold its agreement referred to in the immediately preceding sentence. Such indemnity and reimbursement of expenses shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of such securities by such Holder.

(c) Indemnification similar to that specified in the preceding paragraphs (a) and (b) of this Section 2.9 (with appropriate modifications) shall be given by the Company and each Participating Holder with respect to any required registration or other qualification of securities under any applicable securities and state “blue sky” laws.

(d) Any Person entitled to indemnification under this Agreement shall notify promptly the indemnifying party in writing of the commencement of any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Section 2.9, but the failure of any indemnified party to provide such notice shall not relieve the indemnifying party of its obligations under the preceding paragraphs of this Section 2.9, except to the extent the indemnifying party is materially and actually prejudiced thereby and shall not relieve the indemnifying party from any liability that it may have to any indemnified party otherwise than under this Section 2.9. In case any action or proceeding is brought against an indemnified party and such indemnified party shall have notified the indemnifying party of the commencement thereof (as required above), the indemnifying party shall be entitled to participate therein and, unless in the reasonable opinion of outside counsel to the indemnified party a conflict of interest between such indemnified and indemnifying parties may exist in respect of such Claim, to assume the defense thereof jointly with any other indemnifying party similarly notified, to the

extent that it chooses, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party that it so chooses, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that (i) if the indemnifying party fails to take reasonable steps necessary to defend diligently the action or proceeding within thirty (30) days after receiving notice from such indemnified party that the indemnified party believes it has failed to do so; (ii) if such indemnified party who is a defendant in any action or proceeding that is also brought against the indemnifying party reasonably shall have concluded that there may be one or more legal or equitable defenses available to such indemnified party that are not available to the indemnifying party or that may conflict with or are different from those available to another indemnified party with respect to such Claim; or (iii) if representation of both parties by the same counsel is otherwise inappropriate under applicable standards of professional conduct, then, in any such case, the indemnified party shall have the right to assume or continue its own defense and the indemnifying party shall be liable for any expenses therefor. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(e) If for any reason the foregoing indemnity is unavailable, unenforceable or is insufficient to hold harmless an indemnified party under Sections 2.9(a), (b) or (c), then each applicable indemnifying party shall contribute to the amount paid or payable to such indemnified party as a result of any Claim in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and the indemnified party, on the other hand, with respect to such Claim. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. If, however, the allocation provided in the second preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative faults but also the relative benefits of the indemnifying party and the indemnified party as well as any other relevant equitable considerations. The parties hereto agree that it would not be just and equitable if any contribution pursuant to this Section 2.9(e) were to be determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in the preceding sentences of this Section 2.9(e). The amount paid or payable in respect of any Claim shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such Claim. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act)

shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. Notwithstanding anything in this Section 2.9(e) to the contrary, no indemnifying party (other than the Company) shall be required pursuant to this Section 2.9(e) to contribute any amount greater than the amount of the net proceeds received by such indemnifying party from the sale of Registrable Securities pursuant to the registration statement giving rise to such Claim, less the amount of any indemnification payment made by such indemnifying party pursuant to Sections 2.9(b) and (c). In addition, no Holder of Registrable Securities or any Affiliate thereof shall be required to pay any amount under this Section 2.9(e) unless such Person or entity would have been required to pay an amount pursuant to Section 2.9(b) if it had been applicable in accordance with its terms.

(f) The indemnity and contribution agreements contained herein shall be in addition to any other rights to indemnification or contribution that any indemnified party may have pursuant to law or contract and shall remain operative and in full force and effect regardless of any investigation made or omitted by or on behalf of any indemnified party and shall survive the transfer of the Registrable Securities by any such party.

(g) The indemnification and contribution required by this Section 2.9 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or expense, loss, damage or liability is incurred; provided, however, that the recipient thereof hereby undertakes to repay such payments if and to the extent it shall be determined by a court of competent jurisdiction that such recipient is not entitled to such payment hereunder.

2.10. Limitations on Registration of Other Securities; Representation. From and after the date of this Agreement, for so long as the Registrable Securities beneficially owned by the Shareholders constitute at least ten percent (10%) of the outstanding Shares, the Company shall not, without the prior written consent of the Shareholders, enter into any agreement with any holder or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are (i) more favorable taken as a whole than the registration rights granted to the Holders hereunder unless the Company shall also give such rights to such Holders or (ii) on parity with the registration rights granted to the Holders hereunder.

2.11. No Inconsistent Agreements. The Company shall not hereafter enter into any agreement with respect to its securities that is inconsistent in any material respects with the rights granted to the Holders in this Agreement.

Section 3. Underwritten Offerings.

3.1. Requested Underwritten Offerings. If requested by the underwriters for any underwritten offering pursuant to a registration requested under Section 2.1, the Company shall enter into a customary underwriting agreement with the underwriters. Such underwriting agreement shall (i) be reasonably satisfactory in form and substance to the Majority Participating Holders, (ii) contain terms not materially inconsistent with the provisions of this Agreement to

the extent the underwriters of such offering agree to such terms and (iii) contain such representations and warranties by, and such other agreements on the part of, the Company and such other terms as are customary and generally prevailing in agreements of that type, including, without limitation, indemnities and contribution agreements as are customary for the lead underwriter for such offering and agreed to by the Majority Participating Holders. Any Participating Holder shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Participating Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Participating Holder; provided, however, that the Company shall not be required to make any representations or warranties with respect to written information specifically provided by a Participating Holder for inclusion in the registration statement. Unless otherwise agreed by the Majority Participating Holders and the underwriters, each such Participating Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Participating Holder, its ownership of and title to the Registrable Securities, any written information specifically provided by such Participating Holder for inclusion in the registration statement and its intended method of distribution; and any liability of such Participating Holder to any underwriter or other Person under such underwriting agreement for indemnity, contribution or otherwise shall in no case be greater than the amount of the net proceeds received by such Participating Holder upon the sale of Registrable Securities pursuant to such underwriting agreement and in no event shall relate to anything other than information about such Holder specifically provided by such Holder for use in the registration statement and prospectus (in each case unless otherwise agreed by the underwriters and the Majority Participating Holders).

3.2. Piggyback Underwritten Offerings. In the case of a registration pursuant to Section 2.2, if the Company shall have determined to enter into an underwriting agreement in connection therewith, all of the Participating Holders’ Registrable Securities to be included in such registration shall be subject to such underwriting agreement. Any Participating Holder shall be a party to such underwriting agreement and may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters shall also be made to and for the benefit of such Participating Holder and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement be conditions precedent to the obligations of such Participating Holder; provided, however, that the Company shall not be required to make any representations or warranties with respect to written information specifically provided by a Participating Holder for inclusion in the registration statement. Unless otherwise agreed by the Majority Participating Holders and the underwriters, each such Participating Holder shall not be required to make any representations or warranties to or agreements with the Company or the underwriters other than representations, warranties or agreements regarding such Participating Holder, its ownership of and title to the Registrable Securities, any written information specifically provided by such Participating Holder for inclusion in the registration statement and its intended method of distribution; and any liability of such Participating Holder to any

underwriter or other Person under such underwriting agreement shall in no case be greater than the amount of the net proceeds received by such Participating Holder upon the sale of Registrable Securities pursuant to such underwriting agreement and in no event shall relate to anything other than information about such Holder specifically provided by such Holder for use in the registration statement and prospectus (in each case unless otherwise agreed by the underwriters and Majority Participating Holders).

Section 4. General.

4.1. Rule 144 and Rule 144A. The Company covenants that (i) so long as it remains subject to the reporting provisions of the Exchange Act, it will use commercially reasonable efforts to timely file the reports required to be filed by it under the Exchange Act (including, but not limited to, the reports under Sections 13 and 15(d) of the Exchange Act referred to in subparagraph (c)(1)(i) of Rule 144 under the Securities Act, as such Rule may be amended (“Rule 144”)) or, if the Company is not required to file such reports, it will, upon the request of any Holder, make publicly available other information so long as necessary to permit sales by such Holder under Rule 144, Rule 144A under the Securities Act, as such Rule may be amended (“Rule 144A”), or any similar rules or regulations hereafter adopted by the SEC, and (ii) it will take such further action as any Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (A) Rule 144, (B) Rule 144A or (C) any similar rule or regulation hereafter adopted by the SEC. Upon the reasonable request of any Holder of Registrable Securities, the Company will deliver to such Holder a written statement as to whether it has complied with such requirements. To the extent any Holder desires to sell Registrable Securities pursuant to Rule 144, the Company agrees to provide customary instructions to the transfer agent to remove any restrictive legends from such Shares and to provide or cause any customary opinions of counsel to be delivered to the transfer agent in connection with any such sale. In addition, the Company agrees to remove any restrictive legend from the Registrable Securities upon the reasonable request of any Holder as soon as reasonably permitted by applicable law and customary practice (including customary transfer agent practices).

4.2. Nominees for Beneficial Owners. If Registrable Securities are held by a nominee for the beneficial owner thereof, the beneficial owner thereof may, at its option, be treated as the Holder of such Registrable Securities for purposes of any request or other action by any Holder or Holders of Registrable Securities pursuant to this Agreement (or any determination of any number or percentage of shares constituting Registrable Securities held by any Holder or Holders of Registrable Securities contemplated by this Agreement); provided, however, that the Company shall have received assurances reasonably satisfactory to it of such beneficial ownership.

4.3. Amendments and Waivers. For three years following the date hereof, no provision of this Agreement may be amended or modified unless such amendment or modification is approved by a majority of the Foxtrot Independent Directors (as defined in the Stockholders Agreement, dated as of [●], by and among the Company, SCR-Sibelco NV and

the other stockholders of the Company party thereto) or by the sole Foxtrot Independent Director, so long as at least one Foxtrot Independent Director is a member of the Board of Directors of the Company. Additionally, except as otherwise provided herein, no modification, amendment or waiver of any provision of this Agreement shall be effective against the Company or any Holder unless such modification, amendment or waiver is approved in writing by the Company and such Holder. No waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provision hereof (whether or not similar). No failure or delay on the part of any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof or of any other or future exercise of any such right, power or privilege.

4.4. Notices. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or email of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent after normal business hours of the recipient; or (d) on the third (3^rd) day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid. Such communications must be sent to the respective parties at the following addresses (or at such other address for a party as shall be specified in a notice given in accordance with this Section 4.4):

If to any other Holder, at such Holder’s address as set forth on such Holder’s signature page hereto or to an Assumption Agreement.

4.5. Successors and Assigns. Except as otherwise provided herein, this Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and the respective successors, permitted assigns, heirs and personal representatives of the parties hereto, whether so expressed or not. This Agreement may not be assigned by the Company without the prior written consent of the Shareholders. No Holder shall have the right to assign all or part of its rights and obligations under this Agreement without the prior written consent of the other parties hereto; provided, that any Holder may assign this Agreement to one or more of its Affiliates without the prior written consent of the other parties hereto, and any Holder may assign this Agreement to one or more third parties who acquire Shares from such Holder other than in a public underwritten offering or sales generally into the open market pursuant to Rule 144 so long as the Shares being acquired by such third party or parties has an aggregate market value of at least the Minimum Threshold; provided, further, that such Holder’s Affiliate (or Affiliates) or other permitted transferee executes and delivers to the Company an Assumption Agreement. Upon any such assignment, such assignee shall have and be able to exercise and enforce all rights of the assigning Holder that are assigned to it and, to the extent such rights are assigned, any reference to the assigning Holder shall be treated as a reference to the assignee. If any Holder shall acquire additional Registrable Securities, such Registrable Securities shall be subject to all of the terms, and entitled to all the benefits, of this Agreement.

4.6. Entire Agreement. This Agreement and the other documents referred to herein or delivered pursuant hereto that form part hereof constitute the entire agreement and understanding between the parties hereto, and supersedes all prior agreements and understandings, relating to the subject matter hereof.

4.7. Governing Law; Submission to Jurisdiction; Waiver of Jury Trial. This

Agreement shall be governed by and construed in accordance with the internal laws of the State of New York without giving effect to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than those of the State of New York.

A Holder who previously has given the Company an Opt-Out Request may revoke such request at any time, and there shall be no limit on the ability of a Holder to issue and revoke subsequent Opt-Out Requests; provided that each Holder shall use commercially reasonable efforts to minimize the administrative burden on the Company arising in connection with any such Opt-Out Requests.

Section 2.2 Assumption of Assumed Liabilities. The Transferor hereby assigns and transfers (collectively, the Assignment) to the Transferee the Assumed Liabilities. The Transferee hereby accepts the Assignment and assumes and agrees to pay or otherwise perform or discharge, when due, all of the Assumed Liabilities.

The date on which the Closing occurs is referred to in this Agreement as the Closing Date.

Upon the terms and subject to the conditions set forth herein, the Transferee agrees to issue, transfer and deliver to the Transferor, and the Transferor hereby agrees to accept and acquire from the Transferee, the Shares at the Closing, free and clear of all Encumbrances (other than restrictions on transfer imposed by state and federal securities laws).

Section 2.7 Consents.

(a) Notwithstanding any other provision of this Agreement, this Agreement does not constitute an agreement to sell, convey, assign, assume, transfer or deliver any interest in any Transferred Asset, or any claim, right, benefit or obligation arising thereunder or resulting therefrom if a sale, conveyance, assignment, assumption, transfer or delivery, or an attempt to make such a sale, conveyance, assignment, assumption, transfer or delivery, without the consent of a third party would (i) constitute a breach or other contravention of any Applicable Law or the rights of such third party, (ii) be ineffective with respect to any party to a Contract concerning such Transferred Asset or (iii) upon transfer, in any way adversely affect the rights of the Transferee under such Transferred Asset. If the sale, conveyance, assignment, transfer or delivery by the Transferor to the Transferee of any interest in, or assumption by the Transferee of any liabilities or obligations under, any Transferred Asset requires the consent of a third party, or, with respect to Transferred Contracts, a novation approved by the relevant Governmental Authority or consent of the Contract counterparty, then such sale, conveyance, assignment, transfer, delivery or assumption will be subject to such consent or novation being obtained. Without limiting Section 2.7(b), if any Transferred Asset may not be assigned to the Transferee by reason of the absence of any such consent, the Transferee will not be required to assume any Assumed Liability arising under such Transferred Asset.

(b) If any consent in respect of an Transferred Asset has not been obtained on or before the Closing Date, the Transferor will continue to use all commercially reasonable efforts to obtain such consent as promptly as practicable after the Closing until such time as such consent has been obtained and to cooperate in any lawful and reasonable arrangement which will provide the Transferee the benefits including any indemnities of any such Transferred Asset. Once a consent for the sale, conveyance, assignment, assumption, transfer and delivery of an Transferred Asset is obtained, the Transferor will promptly assign, transfer, convey and deliver such Transferred Asset to the Transferee, and the Transferee will assume the obligations under such Transferred Asset assigned to it from and after the date of assignment to the Transferee. If and when such consents are obtained or such other required actions have been taken, the transfer of such Transferred Asset will be effected in accordance with the terms of this Agreement.

(c) The Transferor will hold in trust for and pay to the Transferee as promptly as practicable upon receipt thereof all income, proceeds and other monies received by the Transferor or any member of the Transferor Group in connection with its use of any asset, claim, right or benefit (net of any Taxes, reduced by any deductions available in connection therewith, and any other costs imposed upon the Transferor Group) in connection with the arrangements under this Section 2.7. The Transferee will promptly provide to the Transferor whatever cooperation is required or reasonably requested for the Transferor to meet its obligations on a timely basis under any Contract or in relation to any such asset, claim, right or benefit.

(d) The failure by the Transferor or the Transferee, as applicable, to obtain any required consent in respect of any Transferred Asset on or before the Closing Date will not relieve any Party from its obligation to consummate the transactions contemplated by this Agreement at the Closing.

ARTICLE 3

EMPLOYEE MATTERS

Section 3.1 Transfer by the Transferor. As soon as practicable after the date of this Agreement and unless prohibited by law, the Transferor and the Transferee shall cooperate with each other and take such actions as may be necessary to transfer the employment of each Transferred Employee from the Transferor to the Transferee with effect from the Closing Date on terms comparable in the aggregate to each such Transferred Employee’s then existing terms of employment with the Transferor. Notwithstanding anything else contained in this Agreement, any Liability relating to any Transferred Employee who does not accept employment with Transferee shall constitute an Assumed Liability.

Section 3.2 Cooperation of Transferor and Transferee. The Transferor and the Transferee shall use commercially reasonable endeavours to encourage the Transferred Employees to accept the transfer of employment from the Transferor to the Transferee as contemplated by Section 3.1.

Section 3.3 Welfare Plan Matters; Recognition of Service Credit Under Transferor’s Plans; Waiver of Pre-Existing Conditions and Crediting of Deductibles. No later than the Closing Date, the Transferee shall establish or cause to be established, at its own expense, benefit plans that provide life insurance, health care, dental care, accidental death and dismemberment insurance, disability and other group welfare benefits for the Transferred Employees. The Transferee shall provide to each Transferred Employee full credit for such Transferred Employee’s service with the Transferor prior to the Closing Date for all purposes, including for purposes of any statutory entitlement in accordance with Applicable Law, severance pay calculations and eligibility, vesting, benefit accruals and determination of the level of benefits (including, for purposes of vacation, severance and retirement benefits), under any benefit plan in which such Transferred Employee participates on or following the Closing Date to the same extent recognized by the Transferor immediately prior to the Closing Date, except that such service shall not be required to be recognized to the extent that such recognition would result in a duplication of benefits. The Transferee shall cause (i) the waiver of all limitations as to pre-existing conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to the Transferred Employees under any such welfare benefit plans to the extent that such conditions, exclusions or waiting periods would not apply under the Transferor Plans, and (ii) for the plan year in which the Closing Date occurs (or, if later, in the calendar year in which the Transferred Employees and their dependents commence participation in the applicable Transferee welfare plans), the crediting of each Transferred Employee with any co-payments and deductibles paid prior to participation in such welfare plans in satisfying any applicable deductible or out-of-pocket requirements thereunder.

Section 3.4 Employee Records. The Transferor and the Transferee each shall use its commercially reasonable efforts to provide each other such employee records and information as

is necessary or appropriate to carry out their obligations under Applicable Law (including, without limitation, any relevant privacy protection laws or regulations in any applicable jurisdictions) or as otherwise contemplated by this Agreement, including, without limitation, for the purposes of administering its employee benefit plans and policies.

Section 3.5 Accrued Salary and Paid Time Off. The Transferee shall assume and honor all accrued and unpaid salary, wages and overtime, and accrued and earned but unused vacation time, sick time and other paid time off benefits for each Transferred Employee as of the Closing Date. To the extent that a Transferred Employee is entitled under any Applicable Law or any policy of the Transferor or its Affiliates to be paid for any such accrued and unpaid salary and overtime or accrued or earned but unused vacation time, sick time and other paid time off benefits as of the Closing Date, Transferee shall discharge the Liability for such payment in respect thereof.

Section 3.6 Accrued Bonuses; Long Term Incentive Plan. The Transferee shall assume and honor all accrued annual bonus compensation in respect of each Transferred Employee as of the Closing Date to the extent not already paid prior to the Closing Date, and pay such annual bonus compensation to the Transferred Employees in a manner consistent with the applicable Transferor annual bonus plan to which the relevant annual bonus accrual relates. In addition, the Transferee shall assume and honor all accrued and unpaid cash incentive awards under the Unimin Corporation Long Term Incentive Plan (Revised May 27, 2014) in respect of the Transferred Employees as of the Closing Date, and shall make payments to Transferred Employees in accordance with the terms of such plan as in effect on the Closing Date (subject to modification of the applicable performance goals as reasonably determined to be necessary in good faith by the Transferee to reflect the transactions contemplated hereunder) and any applicable payment elections previously made by such Transferred Employees.

Section 3.7 Flexible Spending Arrangements. The Transferee agrees to cause a flexible spending and dependent care reimbursement account plan of the Transferee (Transferee’s Flex Plan) to accept a spin-off of the flexible spending and dependent care reimbursement accounts from the Transferor’s flexible spending and dependent care reimbursement account plan (Transferor’s Cafeteria Plan) and to honor and continue through the end of the calendar year in which the Closing Date occurs the elections made by each Transferred Employee under the Transferor’s Cafeteria Plan in respect of the flexible spending and dependent care reimbursement accounts that are in effect immediately prior to the Closing Date. As of or as soon as practicable following the Closing Date, the Transferor shall cause to be transferred from the Transferor’s Cafeteria Plan to the Transferee’s Flex Plan the excess of the aggregate accumulated contributions to the flexible spending and dependent care reimbursement accounts made prior to the Closing Date during the year in which the Closing Date occurs by Transferred Employees over the aggregate reimbursement payouts made prior to the Closing Date for such year from such accounts prior to the Closing Date to the Transferred Employees. If the aggregate reimbursement payouts from the flexible spending and dependent care reimbursement accounts made prior to the Closing Date during the year in which the Closing Date occurs made to the Transferred Employees exceed the aggregate accumulated contributions to such accounts prior to the Closing Date for such year by the Transferred Employees, Transferee shall cause such excess to be transferred to the Transferor as soon as practicable following the Closing Date. On and after the Closing Date, Transferee shall assume and be

solely responsible for all claims for reimbursement by the Transferred Employees under the flexible spending and dependent care reimbursement accounts of Transferor’s Cafeteria Plan, whether incurred prior to, on or after the Closing Date, that have not been paid in full as of the Closing Date.

Section 3.8 Tax-Qualified Defined Contribution/Profit Sharing Plans. The Transferee shall take (or cause its Affiliates to take) any and all necessary action to cause the trustee of a tax-qualified defined contribution/profit sharing plan or plans of Transferee or one of its Affiliates, if requested to do so by a Transferred Employee, to accept a direct “rollover” of all or a portion of such Transferred Employee’s account balances (including any outstanding loans) from Transferor’s or its Affiliates’ tax-qualified defined contribution/profit sharing plan or plans, including any such plan that has a qualified cash or deferred arrangement within the meaning of Section 401(k) of the Code.

Section 3.9 Self-Insured Transferor Plan Liabilities. All liabilities arising out of health or disability coverage claims incurred by or on behalf of any Transferred Employee (or his or her covered dependents) under self-insured Transferor Plans shall be reimbursed by the Transferee promptly following receipt of written notice from the Transferor containing the specific financial detail of the applicable claim. Notwithstanding the foregoing, the Transferee’s Liability pursuant to the preceding sentence shall equal the excess of (i) the amount of such claims incurred, over (ii) the aggregate amount of premiums collected or paid from or on behalf of such Transferred Employee for coverage under such self-insured Transferor Plans; provided that the Transferee’s Liability for such claims shall not include any amount of such claims that are paid under any stop-loss insurance policy in force with respect to such Transferor Plan. For purposes of the foregoing, (i) a health claim or Liability is deemed to be incurred upon the rendering of health services giving rise to such claim or Liability, and (ii) a disability claim or Liability is deemed to be incurred upon the date of disability, as determined by the disability benefit claim administrator, giving rise to such claim or Liability.

Section 3.10 Workers’ and Unemployment Compensation. All workers’ compensation liabilities relating to, arising out of, or resulting from any claim by a Transferred Employee that results from an accident, incident or event occurring, or from an occupational disease which becomes manifest as a result of performing services for the Business shall be assumed by the Transferee and covered by workers’ compensation insurance coverage to be obtained by the Transferee. To the extent that the Transferee is unable to cover any such liabilities under workers’ compensation insurance coverage to be obtained by the Transferee, such liabilities will remain under the worker’s compensation insurance coverage of the Transferor and the Transferee shall, promptly following receipt of written notice from the Transferor containing the specific financial detail of the applicable claim, reimburse the Transferor for any such liabilities to the extent that the payment for such liabilities are subject to a deductible under the applicable Transferor insurance policy or exceed the coverage limits under the applicable Transferor insurance policy or stop-loss coverage. Effective as of the Closing Date, the Transferee will be responsible for obtaining workers’ compensation insurance, including providing all collateral required by the insurance carriers and providing all notices to Transferred Employees required by applicable workers’ compensation laws and establishing new or transferred unemployment insurance employer accounts, policies and claims handling contracts with the applicable government agencies

Section 3.11 Company Car Leases. The Transferee shall assume and honor all automobile leases and liabilities thereunder relating to automobiles leased by the Transferor for the benefit of Transferred Employees as of the Closing Date. To the extent that the Transferor is unable to assign, and the Transferee is unable to assume, such automobile leases due to the limitations of the applicable lease Contracts or otherwise, such automobile leases will remain with the Transferor and the Transferee shall, on a monthly basis and promptly following receipt of written notice from the Transferor containing the specific financial detail of the applicable monthly lease Liability, reimburse the Transferor for any such liabilities incurred under such automobile leases.

Section 3.12 Employee Tax Matters. Transferor and its Affiliates and Transferee shall adopt the “alternate procedure” for preparing and filing IRS Forms W-2 (Wage and Tax Statements), as described in Revenue Procedure 2004-53. Under this procedure, Transferee, as successor employer, shall provide, as applicable, all required Forms W-2 to all Transferred Employees subject to income Taxes in the United States reflecting all wages paid and Taxes withheld by Transferor or its Affiliate, as the predecessor and Transferee as the successor employer for the entire year in which the Closing Date occurs. In addition, Transferor and its Affiliates and Transferee shall adopt the “alternative procedure” of Revenue Procedure 2004-53 for purposes of filing IRS Forms W-4 (Employee’s Withholding Allowance Certificate) and W-5 (Earned Income Credit Advance Payment Certificate).

Section 3.13 Collectively Bargained Employees. The Transferee agrees to take all actions that are legally required to assume each collective bargaining agreement and all liabilities arising on or following the Closing Date thereunder in respect of any Transferred Employees pursuant to each collective bargaining agreement that covers any such Transferred Employees. Notwithstanding anything to the contrary in this ARTICLE 3, the Transferee further agrees that the provisions of this ARTICLE 3 shall be subject to any applicable provisions of any collective bargaining agreement in respect of the Transferred Employees, and to the extent that the provisions of this ARTICLE 3 are inconsistent with or otherwise in conflict with the provisions of any such collective bargaining agreement, the provisions of such collective bargaining agreement shall govern and control. Without limiting the generality of the provisions of Section 3.1, effective as of the Closing, the Transferred Employees covered by any collective bargaining agreement assumed in the manner contemplated hereunder shall cease to be employed by the Transferor and shall become the employees of the Transferee. The Transferor and the Transferee shall cooperate in connection with any required notification to the Transferred Employees, the representatives thereof, the applicable unions or any relevant Governmental Authorities concerning the transactions contemplated hereby and shall take such other reasonable actions as determined in good faith by each of them to be necessary to cause the provisions of this section to apply without limitation to the maximum extent permitted under Applicable Law.

Section 3.14 No Obligation. Nothing contained herein shall be construed as (i) requiring the Transferor or the Transferee to continue any specific employee benefit plan, or (ii) an amendment to any compensation or benefit plan or arrangement for any purpose. The Transferor and the Transferee acknowledge and agree that all provisions contained in this ARTICLE 3 are included for the sole benefit of the Transferor and the Transferee, and that nothing in this Agreement, whether express or implied, will create any third-party beneficiary or other rights (x) in any other person, including any Transferred Employee or any dependent or beneficiary thereof, or (y) to continued employment with the Transferee for any specified period of time following the Closing Date.

Section 4.2 Indemnification by the Transferee. Subject to the limitations expressly set forth in this ARTICLE 4, Sibelco and the Transferee shall indemnify, defend and hold harmless the Transferor and its Affiliates and each of its and their directors, officers, employees, shareholders, members, partners, agents, successors and assigns (collectively, the Transferor Indemnified Parties and, together with the Transferee Indemnified Parties, the Indemnified Parties and, each, an Indemnified Party) from and against any and all Losses incurred by the Transferor Indemnified Parties to the extent, directly or indirectly, arising or resulting from any Transferred Asset or Assumed Liability.

Section 4.3 Calculation of Losses. Notwithstanding anything to the contrary in this Agreement, a Party shall not be liable for any Loss incurred by any other Party:

(a) to the extent that the Liability giving rise to the Loss is attributable to: (i) an action or omission by the Transferee or its Affiliates (other than members of the Transferor Group), or its or their respective officers, directors, employees or agents (in each case to the extent acting in such capacity), after the Closing that is expressly required by this Agreement or at the express written direction of the Transferor or any member of the Transferor Group (or its or their respective officers, directors, employees or agents); (ii) an action or omission by any member of the Transferor Group, or its or their respective officers, directors, employees or agents (in each case to the extent acting in such capacity), after the Closing that is expressly required by this Agreement or at the express written direction of Sibelco or Sibelco’s Affiliates (other than the Transferor Group) (or its or their respective officers, directors, employees or agents); or (iii) a breach by the other Party or its Affiliates (or its or their respective officers, directors, employees or agents) of any obligation under this Agreement; or

(b) for any punitive damages, except to the extent actually required by a Governmental Authority to be paid to a third party.

Section 4.4 Mitigation of Losses. Each Indemnified Party shall, and cause its Affiliates to, use their respective commercially reasonable efforts to mitigate any Loss upon becoming aware of any event or circumstance that would be reasonably expected to, or does, give rise thereto, including incurring commercially reasonable costs in respect of such indemnifiable Loss.

Section 4.5 Third Party Claims; Notice of Direct Claims.

(a) In order for any Person to be entitled to any indemnification provided for under this ARTICLE 4 in respect of, arising out of or involving a claim made by any Person (other than a Party) against an Indemnified Party (a Third Party Claim), such Indemnified Party must notify the indemnifying Party in writing of the Third Party Claim within ten (10) Business Days after receipt by such Indemnified Party of written notice of the Third Party Claim (or sooner, to the extent the nature of the Third Party Claim requires a response in a shorter period of time); provided that failure to give such notice shall not affect the right to indemnification provided hereunder except to the extent the indemnifying Party shall have been materially prejudiced as a result of such failure. Thereafter, the Indemnified Party shall deliver to the indemnifying Party, as promptly as reasonably practicable following such Indemnified Party’s receipt thereof, copies of all written notices and documents (including any court papers) received by such Indemnified Party relating to the Third Party Claim.

(b) If a Third Party Claim is made against an Indemnified Party, the indemnifying Party shall be entitled (at its election) to assume the defense of such Third Party Claim with counsel reasonably acceptable to the Indemnified Party by giving to the Indemnified Party, within twenty (20) days of receipt of a written notice of the Third Party Claim, written notice of its intention to assume the defense of such Third Party Claim. If the indemnifying Party assumes such defense, the Indemnified Party shall nonetheless have the right to employ counsel separate from the counsel employed by the indemnifying Party; provided that the indemnifying Party shall not be liable to such Indemnified Party for any fees of such separate counsel with respect to the defense of such Third Party Claim, unless the engagement of such separate counsel is consented to by the indemnifying Party in writing or in the reasonable opinion of the Indemnified Party, a conflict or potential conflict exists between such Indemnified Party and the indemnifying Party that would make such separate representation advisable. If the indemnifying Party does not assume such defense, and for any period during which the indemnifying Party has not assumed such defense, the indemnifying Party shall be liable for the reasonable fees and expenses of one single counsel employed (and reasonably acceptable to the indemnifying Party) by such Indemnified Party (which reasonable fees and expenses shall be considered Losses for purposes of this Agreement). If the indemnifying Party chooses to defend a Third Party Claim or prosecute a claim in connection therewith, each Indemnified Party shall provide all necessary cooperation in such defense or prosecution, including in making any counterclaim against the Person asserting the Third Party Claim, or any cross-complaint against any Person (other than the indemnifying Party or any of its Affiliates). Notwithstanding the foregoing, the indemnifying Party will not have any right to assume the defense of a Third Party Claim where such Third Party Claim (i) seeks injunctive or equitable relief against the Indemnified Party or any of its Affiliates or (ii) involves criminal allegations.

(c) If the indemnifying Party assumes the defense of a Third Party Claim, the indemnifying Party may not settle, compromise or discharge such Third Party Claim without the prior written consent of the Indemnified Party, which consent will not be unreasonably withheld, conditioned or delayed; provided, that the consent of the Indemnified Party will not be required if: (i) the indemnifying Party agrees in writing to pay any amounts payable pursuant to such settlement or any judgment; (ii) such settlement includes a full, complete and unconditional written release of each Indemnified Party from further Liability; (iii) except in any case where

court approval is needed of such a settlement, such settlement does not include any statement as to or an admission of fact, culpability or a failure to act, by or on behalf of any Indemnified Party or its Affiliates; and (iv) such settlement does not in any manner involve any injunction or equitable relief against any Indemnified Party or its Affiliates. The Indemnified Party will not agree to any settlement of, or the entry of any judgment (other than a judgment of dismissal on the merits with prejudice and without costs) arising from, any Third Party Claim without the prior written consent of the indemnifying Party, which consent will not be unreasonably withheld, conditioned or delayed.

(d) In the event an Indemnified Party has a claim against an indemnifying Party under Section 4.1 or Section 4.2, as applicable, that does not involve a Third Party Claim, such Indemnified Party shall deliver notice of such claim to the indemnifying Party stating the amount of the Loss, if known, and method of computation thereof, and containing a reference to the provisions of this Agreement in respect of which such right of indemnification is claimed or arises, within twenty (20) Business Days of becoming aware of the facts or circumstances giving rise to such claim; provided that failure to give such notice shall not affect the indemnification provided hereunder except to the extent the indemnifying Party shall have been materially prejudiced as a result of such failure. The Indemnified Party and the indemnifying Party shall, for a period of not less than twenty (20) Business Days following receipt by the indemnifying Party of the notice of such claim, negotiate in good faith to resolve the claim, and such Indemnified Party shall not commence proceedings with respect to such claim prior to the end of such period.

Section 4.6 Exclusivity of Remedies. Following the Closing, (i) this ARTICLE 4 shall provide the exclusive remedy of the Transferee for any claim (other than a claim with respect to Taxes) arising out of this Agreement or the transactions contemplated hereby, and (ii) pursuant to ARTICLE 5, the Tax Matters Agreement shall provide the exclusive remedy of the Transferee for any claim with respect to Taxes arising out of this Agreement or the transactions contemplated hereby. Notwithstanding anything to the contrary contained in this Agreement, no breach of any representation, warranty, covenant or agreement contained herein shall give rise to any right on the part of any Party, after consummation of the transactions contemplated hereby, to rescind this agreement or any of the transactions contemplated hereby.

Section 4.7 Double Recovery. No Indemnified Party shall be entitled to recover any amount pursuant to any provision of this Agreement in respect of any claim to the extent such Indemnified Party has already recovered that amount in respect of such claim under the same or any other provision of this Agreement or pursuant to any other agreement with any Affiliate of the other Indemnified Party, or to the extent that recovery has already been made under this Agreement in respect of the same subject matter and in the amount of the Loss claimed.

Section 6.4 Amendment and Waivers. This Agreement may not be amended or modified prior to the Effective Time (or the earlier termination of the Merger Agreement in accordance with its terms), or, except by an instrument in writing, consented to in writing by each of the Parties (and subject to approval by the Board of Directors of the Transferor (acting pursuant to Section 2.3(a)(iii) of the Stockholders Agreement of the Transferor)), thereafter.

further exercise of such right or remedy or the exercise of any other right or remedy; and (iv) after the Effective Time, the Transferor may only, in the case of each of clauses (a), (b) and (c), act pursuant to Section 2.3(a)(iii) of the Stockholders Agreement of the Transferor.

Section 6.5 Entire Agreement. This Agreement (including the Schedules hereto and, solely to the extent referenced herein, the Merger Agreement) and the Tax Matters Agreement contain the entire agreement and understanding between the Parties with respect to the subject matter hereof and supersedes all prior agreements and understandings (whether oral or written) relating to such subject matter. None of the Parties shall be liable or bound to any other Party in any manner by any representations, warranties or covenants relating to such subject matter except as specifically set forth herein or therein.

Section 6.6 Assignment, Successors and Third Party Rights. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by any Party without the prior written consent of the other Parties, and any such assignment without such prior written consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective permitted successors and assigns and nothing herein expressed or implied shall give, or be construed to give, to any Person, other than the Parties and such successors and permitted assigns, any legal or equitable right, remedies or claims under or with respect to this Agreement or any provisions hereof.

Section 6.7 Severability. If any term or other provision of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect and shall in no way be affected, impaired or invalidated. Upon a determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by Applicable Law in a mutually acceptable manner to the end that the transactions contemplated by this Agreement are fulfilled to the fullest extent possible.

Section 6.11 Specific Performance. The Parties acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were

not performed in accordance with their specific terms or were otherwise breached, and that monetary damages, even if available, would not be an adequate remedy therefor. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the performance of terms and provisions of this Agreement in any court referred to Section 6.10 above, without proof of actual damages (and each Party hereby waives any requirement for the securing or posting of any bond in connection with such remedy), this being in addition to any other remedy to which they are entitled at law or in equity. The Parties further agree not to assert that a remedy of specific enforcement is unenforceable, invalid, contrary to law or inequitable for any reason, nor to assert that a remedy of monetary damages would provide an adequate remedy for any such breach.

Section 6.12 Jurisdiction; Waiver of Jury Trial.

(a) In any Action between the Parties arising out of or relating to this Agreement or any of the transactions contemplated hereby, each of the Parties (i) irrevocably and unconditionally consents and submits to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware in and for New Castle County, Delaware or any federal court sitting in the State of Delaware; (ii) agrees that it will not attempt to deny or defeat such jurisdiction by motion or other request for leave from such court; and (iii) agrees that it will not bring any such action in any court other than the Court of Chancery for the State of Delaware in and for New Castle County, Delaware, or any federal court sitting in the State of Delaware and appellate courts thereof.

If the Non-Filing Party timely submits a Tax Return Objection Notice, then the Parties shall work together in good faith to resolve the objections raised in such notice; provided that, if the Parties are not able to resolve all objections raised in a Tax Return Objection Notice prior to the due date for filing the applicable Tax Return (including extensions), such Tax Return shall be filed as prepared by the Filing Party, but reflecting all non-disputed comments provided by the Non-Filing Party, and, at the Non-Filing Party’s election, the remaining disputed items shall be referred for resolution pursuant to Section 14, in which case, after the Tax Advisor finally resolves the dispute, such Tax Return shall be amended as necessary to reflect the determination of the Tax Advisor.

5. Tax Payments.

5.3 Payment of Taxes With Respect to Joint Taxes. In the case of any Tax Return reflecting Taxes for which both Unimin or any Affiliate of Unimin, on the one hand, and HPQ Co or any Affiliate of HPQ Co, on the other, are responsible under Section 2:

(a) Computation and Payment of Tax Due. At least five Business Days prior to any Payment Date for any Tax Return, the Responsible Company shall compute the amount of Taxes

required to be paid to the applicable Tax Authority with respect to such Tax Return on such Payment Date. The Responsible Company shall pay such amount to such Tax Authority on or before such Payment Date (and provide notice and proof of payment to the other Company).

(b) Computation and Payment of Liability With Respect To Tax Due. Within 30 days following the earlier of (i) the due date (including extensions) for filing any such Tax Return (excluding any Tax Return with respect to payment of estimated Taxes or Taxes due with a request for extension of time to file) or (ii) the date on which such Tax Return is filed, if Unimin is the Responsible Company, then HPQ Co shall pay to Unimin the amount allocable to the HPQ Co Group under the provisions of Section 2, and if HPQ Co is the Responsible Company, then Unimin shall pay to HPQ Co the amount allocable to the Unimin Group under the provisions of Section 2, in each case, plus interest computed at the Prime Rate on the amount of the payment based on the number of days from the earlier of (i) the due date of the Tax Return (including extensions) or (ii) the date on which such Tax Return is filed, to the date of payment.

(c) Adjustments Resulting in Underpayments. In the case of any adjustment pursuant to a Final Determination with respect to any Tax Return, the Responsible Company shall pay to the applicable Tax Authority when due any additional Tax due with respect to such Return required to be paid as a result of such adjustment pursuant to a Final Determination. The Responsible Company shall compute the amount attributable to the HPQ Co Group (or the Unimin Group) in accordance with Section 2 and HPQ Co shall pay to Unimin any amount due Unimin (or Unimin shall pay HPQ Co any amount due HPQ Co) within 30 days from the later of (i) the date the additional Tax was paid by the Responsible Company or (ii) the date of receipt of a written notice and demand from the Responsible Company for payment of the amount due, accompanied by evidence of payment and a statement detailing the Taxes paid and describing in reasonable detail the particulars relating thereto. Any payments required under this Section 5.3(c) shall include interest computed at the Prime Rate based on the number of days from the date the additional Tax was paid by the Responsible Company to the date of the payment under this Section 5.3(c).

5.4 Indemnification Payments. All indemnification payments under this Agreement shall be made by Sibelco, Unimin, or HPQ Co, as applicable, directly to Sibelco, Unimin, or HPQ Co, as applicable, and all such payments shall, to the extent applicable, be treated by Sibelco, Unimin, HPQ Co and their respective Affiliates in the manner set forth in Section 13; provided, however, that if the Companies mutually agree with respect to any such indemnification payment, any member of the Unimin Group, on the one hand, may make such indemnification payment to any member of the HPQ Co Group, on the other hand, and vice versa.

5.5 Recomputations. Notwithstanding anything to the contrary set forth in this Agreement, if one Party makes a payment on account of Taxes to another Party under this Agreement, including with respect to a Tax indemnified against, and the amount of such payment, because of an amended Return, Tax Authority adjustment, Final Determination, carryover of a Tax Item or otherwise, would be increased or decreased if computed at a later date, at the written request of either Party, the Parties shall recompute such payment at such later date and an appropriate adjusting payment shall be made between the Parties promptly following such recomputation.

6. Tax Benefits.

6.1 General. Except as set forth below, Unimin shall be entitled to any refund or portion thereof (and any interest thereon received from the applicable Tax Authority) of Income Taxes and Other Taxes for which Unimin is liable hereunder, HPQ Co shall be entitled to any refund or portion thereof (and any interest thereon received from the applicable Tax Authority) of Income Taxes and Other Taxes for which HPQ Co is liable hereunder and a Company receiving a refund (including by way of credit or offset) to which another Company is entitled (in whole or in part) hereunder shall pay over such refund or portion thereof (net of charges imposed on the Company receiving the refund) to such other Company within 30 days after such refund is received (together with interest computed at the Prime Rate based on the number of days from the date the refund was received to the date the refund was paid over).

6.2 Reimbursements. If a member of the HPQ Co Group actually realizes in cash any Tax Benefit as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the Unimin Group is liable hereunder (or to any Tax Attribute of a member of the Unimin Group) and such Tax Benefit would not have arisen but for such adjustment (determined on a “with and without” basis (treating any such Tax Benefit as the last item claimed for the taxable year, including after the utilization of any available net operating loss carryforwards)), or if a member of the Unimin Group actually realizes in cash any Tax Benefit as a result of an adjustment pursuant to a Final Determination to any Taxes for which a member of the HPQ Co Group is liable hereunder (or to any Tax Attribute of a member of the HPQ Co Group) and such Tax Benefit would not have arisen but for such adjustment (determined on a “with and without” basis (treating any such Tax Benefit as the last item claimed for the taxable year, including after the utilization of any available net operating loss carryforwards)), HPQ Co or Unimin, as the case may be, shall make a payment to either Unimin or HPQ Co, as appropriate, within 30 days following such actual realization of the Tax Benefit, in an amount equal to such Tax Benefit actually realized in cash (including any Tax Benefit actually realized as a result of the payment) plus interest on such amount computed at the Prime Rate based on the number of days from the date of such actual realization of the Tax Benefit to the date of payment of such amount under this Section 6.2. For the avoidance of doubt, a Tax Benefit is actually realized when the amount of Tax payable is reduced below the amount that would otherwise be payable without the Tax Benefit.

6.3 Cooperation. If as a result of (x) an assessment by a Tax Authority, (y) an amended Return or (z) otherwise, there is an increase in Taxes for which one Group is liable hereunder because of additional income, reduction in a Tax Attribute or otherwise, then the other Group shall at the request of the first Group file an amended Return or otherwise pursue any Tax Benefits claim available to the other Group as a result of the Tax adjustment to the first Group, provided that the first Group has furnished the other Group with (i) an opinion of a Tax Advisor reasonably satisfactory to the other Group to the effect that it is at least more likely than not that the other Group will prevail in obtaining Tax Benefits or otherwise reducing the Taxes of the other Group because of the Tax adjustment to the first Group, and (ii) an acknowledgement that the first Group will reimburse the other Group for all reasonable out-of-pocket expenses incurred by the other Group in connection with making such Tax Benefit claim.

Such notice shall provide that the notifying Company may seek indemnification from the other Company or Companies under this Agreement and shall attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters. A failure of a Company to comply with this Section 10.1 shall not relieve the indemnifying party of its indemnification obligation under this Agreement, except to the extent such failure materially prejudices the ability of the indemnifying party to contest the liability for the relevant Tax or increases the amount of such liability.

10.2 Control of Tax Contests.

(a) Separate Company Taxes. In the case of any Tax Contest with respect to any Separate Return for Income Taxes, the Filing Party shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 10.2(e), (f), (g), (h) and (i).

(b) Unimin Group Return. In the case of any Tax Contest with respect to any Unimin Group Return, Unimin shall have exclusive control over the Tax Contest, including exclusive authority with respect to any settlement of such Tax liability, subject to Sections 10.2(e), (f), (g), (h) and (i).

(f) Settlement Rights. For Tax Contests other than those that are jointly controlled by the Parties pursuant to Section 10.2(d), unless waived by the Non-Controlling Party in writing, in connection with any potential adjustment in a Tax Contest as a result of which adjustment the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment (or any payment under Section 6) to the Controlling Party under this Agreement: (i) the Controlling Party shall keep the Non-Controlling Party informed in a timely manner of all actions taken or proposed to be taken by the Controlling Party with respect to such potential adjustment in such Tax Contest; (ii) the Controlling Party shall provide the Non-Controlling Party copies of any written materials relating to such potential adjustment in such Tax Contest received from any Tax Authority; (iii) the Controlling Party shall timely provide the Non-Controlling Party with copies of any correspondence or filings submitted to any Tax Authority or judicial authority in connection with such potential adjustment in such Tax Contest; (iv) the Controlling Party shall consult with the Non-Controlling Party and offer the Non-Controlling Party a reasonable opportunity to comment before submitting any written materials prepared or furnished in connection with such potential adjustment in such Tax Contest; (v) the Controlling Party shall defend such Tax Contest diligently and in good faith; and (vi) the Controlling Party shall not settle or compromise such Tax Contest without the prior written consent of the Non-Controlling Party (not to be unreasonably withheld, conditioned or delayed). The failure of the Controlling Party to take any action specified in the preceding sentence with respect to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was materially prejudiced by such failure. In the case of any Tax Contest described in Section 10.2(a), (b), (c), or (d), “Controlling Party” means the Company entitled to control the Tax Contest under such Section and “Non-Controlling Party” means the other Company or Companies.

(g) Tax Contest Participation. Unless waived by the Non-Controlling Party in writing, the Controlling Party shall provide the Non-Controlling Party with written notice reasonably in advance of, and the Non-Controlling Party shall have the right to attend, any formally scheduled meetings with Tax Authorities or hearings or proceedings before any judicial authorities in connection with any potential adjustment in a Tax Contest pursuant to which the Non-Controlling Party may reasonably be expected to become liable to make any indemnification payment (or any payment under Section 6) to the Controlling Party under this Agreement. The failure of the Controlling Party to provide any notice specified in this Section 10.2(g) to the Non-Controlling Party shall not relieve the Non-Controlling Party of any liability and/or obligation which it may have to the Controlling Party under this Agreement except to the extent that the Non-Controlling Party was materially prejudiced by such failure.

11. Effective Date. This Agreement shall be effective as of the Distribution Date.

12. Survival. This Agreement shall remain in force and be binding so long as the applicable period for assessments or collections of Tax or the right to claim or use any Tax Benefit (including extensions) remains unexpired for any Taxes or Tax Benefits contemplated by, or indemnified against in, this Agreement plus two years; provided that to the extent a claim for indemnification is made prior to the expiration of this Agreement, this Agreement shall survive until such claim is finally resolved.

13. Treatment of Payments.

13.1 General. In the absence of any change in Tax treatment under the Code or other applicable Tax Law, any indemnity payment between HPQ Co and Unimin made under this Agreement, including pursuant to Section 2, 4.3, 5 or 7.4, and any Tax Benefit payment made under this Agreement, including pursuant to Section 6, shall be treated, for all Tax purposes, as made immediately before the Distribution as a distribution (or, as context requires, an assumption of a liability under the Business Contribution Agreement or otherwise) by HPQ Co to (or from) Unimin or as a contribution by Unimin to HPQ Co, as appropriate. To the extent one Company makes a payment of interest to another Company relating to a payment of Tax under this Agreement, the interest payment shall be treated as interest expense to the payor and as interest income by the recipient and the amount of such payment shall not be adjusted to take into account any associated Tax Benefit to the payor or increase in Tax to the recipient.

13.2 After-Tax Basis. All indemnity payments under this Agreement, including pursuant to Section 2, 4.3, 5 or 7.4, shall be (i) increased to take account of any net Tax cost actually incurred by the indemnified party arising from the receipt or accrual of indemnity payments (grossed up for such increase) and (ii) reduced to take account of any net Tax Benefit actually realized by the indemnified party arising from the incurrence or payment of any amount or other loss indemnified against. In computing the amount of any such Tax cost or Tax Benefit,

the indemnified party shall be deemed to recognize all other items of income, gain, loss deduction or credit, including the utilization of any available net operating loss carryforwards, before recognizing any item arising from the receipt of any indemnity payment hereunder or the incurrence or payment of any amount or other loss indemnified against hereunder. For purposes of this Section 13.2, an indemnified party shall be deemed to have “actually incurred” or “actually realized” a net Tax cost or a net Tax Benefit to the extent that, and at such time as, the amount of Taxes payable (including Taxes payable on an estimated basis) by such indemnified party is increased above or reduced below, as the case may be, the amount of Taxes that such indemnified party would be required to pay but for the receipt or accrual of the indemnity payment or the incurrence or payment of such amount indemnified against as the case may be. The Companies shall make any adjusting payment between each other as is required under this Section 13.2 within ten (10) days of the date an indemnified party is deemed to have actually realized or actually incurred each net Tax Benefit or net Tax cost. The amount of any increase or reduction hereunder shall be adjusted to reflect any Final Determination with respect to the indemnified party’s liability for Taxes and any payments necessary to reflect such adjustment shall be made within ten (10) days of such determination.

14. Disagreements.

14.1 General Procedures. The Companies will use commercially reasonable efforts to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement (including those, if any, relating to the interpretation, implementation or compliance with the provisions of this Agreement). In furtherance thereof, in the event of any dispute or disagreement with respect to this Agreement (a “Tax Matters Dispute”) between Sibelco, any member of the Unimin Group and any member of the HPQ Co Group, the Tax departments of the Companies (and their advisers if requested) shall negotiate in good faith to resolve the Tax Matters Dispute. In the event that such good faith negotiations do not resolve the Tax Matters Dispute, any one of the Parties that is party to the dispute may by delivering a request in writing to the other(s), subject the Tax Matters Dispute to the procedures set forth in Section 14.2.

14.2 Tax Advisor Resolution. In the case of any Tax Matters Dispute governed by this Section 14.2, the disputing Parties shall appoint a Tax Advisor to resolve such dispute. In this regard, the Tax Advisor shall make determinations with respect to the disputed items based solely on representations and factual submissions made by the Parties to the Tax Matters Dispute and their respective representatives, and shall not conduct an independent review, and shall function only as an expert and not as an arbitrator and shall be required to make a determination in favor of one Party only. The Parties shall require the Tax Advisor to resolve any Tax Matters Dispute submitted no later than thirty Business Days after submission of such dispute to the Tax Advisor, but (unless otherwise mutually agreed by the Parties) in no event later than the due date for the payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Tax Advisor with respect thereto shall be final and conclusive and binding on the Parties. The Tax Advisor shall resolve any and all Tax Matters Disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with Past Practices, except as otherwise required by applicable Tax Law. The Parties shall require the Tax Advisor to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Tax Advisor shall be borne equally by the prevailing Party or Parties, on the one hand, and the non-prevailing Party or Parties, on the other.

15. Late Payments. Except as otherwise provided in this Agreement, any amount owed by one Company to another Company under this Agreement that is not paid when due shall bear interest from the due date until paid at the Prime Rate plus two percent, compounded semiannually.

16. Expenses. Except as otherwise provided in this Agreement, each Company and its Affiliates shall bear their own expenses incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement.

17. Sibelco Guaranty. Sibelco hereby irrevocably and unconditionally guarantees to Unimin and its Affiliates the due and punctual payment in full of all the payment obligations of HPQ Co and its Affiliates under this Agreement (including under Sections 2, 5, 6, and 7.4(b)) (the “HPQ Co Tax Obligations”). If, for any reason whatsoever, HPQ Co and its Affiliates fail to or are unable to duly, punctually, and fully pay the HPQ Co Tax Obligations, Sibelco will forthwith pay (or cause to be paid) the HPQ Co Tax Obligations. Sibelco agrees that the Sibelco Guaranty is irrevocable, absolute, independent, and unconditional and the Sibelco Guaranty will not be affected by any circumstances that constitute a legal or equitable discharge of a guarantor or surety, other than the payment in full of the HPQ Co Tax Obligations. Without limiting the generality of the foregoing, Sibelco agrees that the Sibelco Guaranty is (i) a guaranty of payment when due and not of collectability or performance, and (ii) independent of the obligations of HPQ Co and its Affiliates under this Agreement and a separate action may be brought against and prosecuted against Sibelco if, but only if, HPQ Co and its Affiliates fail to or are unable to duly, punctually, and fully pay the HPQ Co Tax Obligations, whether or not any action is or may be brought against HPQ Co and its Affiliates.

18.2 Amendment and Waivers. This Agreement may not be amended or modified except by an instrument in writing, consented to in writing by each of the Parties. Each Party may (a) extend the time for performance of any of the obligations or other acts of the other Party, (b) waive any inaccuracies in the representations and warranties of the other Party contained in this Agreement or (c) waive compliance with any of the covenants or conditions for the benefit of such Party contained in this Agreement, provided that (i) any such extension or waiver by a Party will be valid only if set forth in a written document signed on behalf of the Party against whom such extension or waiver is to be effective; (ii) no extension or waiver will apply to any time for performance, inaccuracy in any representation or warranty or noncompliance with any covenant or condition, as the case may be, other than that which is specified in the written extension or waiver and (iii) no failure or delay by a Party in exercising any right or remedy under this Agreement or any of the documents delivered pursuant to this Agreement, and no course of dealing between the Parties, operates as a waiver of such right or remedy, and no single or partial exercise of any such right or remedy precludes any other or further exercise of such right or remedy or the exercise of any other right or remedy.

18.3 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect for so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to either Company. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Companies shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Companies as closely as possible in an acceptable manner in order that the transactions contemplated by this Agreement are consummated as originally contemplated to the greatest extent possible.

18.4 No Duplication of Payment. Notwithstanding anything to the contrary contained herein, nothing in this Agreement shall require a Company to make any payment attributable to any indemnification for Taxes or payment of Taxes hereunder, or to any Tax Benefit, for which payment has previously been compensated by such Company or another Company hereunder.

18.5 Counterparts. This Agreement may be executed and delivered (including by facsimile or portable document format (PDF) transmission) in any number of counterparts, each of which will be deemed to be an original copy of this Agreement and all of which, when taken together, will be deemed to constitute one and the same instrument.

18.6 Governing Law. Each Party irrevocably submits to the exclusive personal jurisdiction of the New York Courts for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby or thereby.

Each Party further agrees that service of any process, summons, notice or document by U.S. registered mail to such Party’s respective address set forth in Section 18.1, shall be effective service of process for any action, suit or proceeding in New York with respect to any matters to which it has submitted to jurisdiction in this Section 18.6. Each Party irrevocably and unconditionally waives any objection to the laying of venue of any Proceeding arising out of this Agreement or the transactions contemplated hereby and thereby in the New York Courts, and hereby and thereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such Proceeding brought in any New York Court has been brought in an inconvenient forum.

18.7 Assignment. Neither this Agreement nor any of the rights, interests or obligations under this Agreement shall be assigned, in whole or in part, by operation of law or otherwise by any Party without the prior written consent of the other Parties, such consent not to be unreasonably withheld, conditioned or delayed. Any purported assignment without such consent shall be void. Subject to the preceding sentences, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective successors and assigns.

DISTRIBUTION AGREEMENT

THIS DISTRIBUTION AGREEMENT (this “Agreement”), is dated as of [●], (the “Effective Date”), by and between Unimin Corporation, a Delaware corporation [(“Producer”)][(“Distributor”)] and SCR-Sibelco NV, a Belgian public company [(“Producer”)][(“Distributor”)].

WHEREAS, Producer seeks to have Distributor serve as a distributor of certain of its Products as hereinafter defined under the terms and conditions set forth herein; and

WHEREAS, Distributor seeks to distribute the Products in accordance with the terms set forth herein and further seeks a license to use certain trademarks owned by Producer in conjunction with its sale of Producer’s Products;

NOW, THEREFORE, the parties, intending to be bound, agree as follows:

1. Appointment of Distributor.

(a) Subject to the provisions of this Agreement, Producer hereby appoints Distributor as an authorized distributor for the Producer materials listed on the attached Exhibit A (“Products”) on an exclusive basis for the Industries listed on attached Exhibit B (each, an “Industry”) within the geographical area listed on attached Exhibit C (the “Trading Area”), and Distributor hereby accepts such appointment. The provisions of this Agreement constitute the entire agreement and understanding between the parties on the subject matter of this Agreement, and except as specifically set forth herein, there are no additional agreements, understandings, representations, covenants, warranties or guaranties, written or oral, between the parties, relating to the subject matter of the Agreement. Prior arrangements, agreements and understandings, if any, are superseded by this Agreement. Distributor may appoint any third party to act as a sub-distributor, upon obtaining Producer’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned.

(b) The relationship of the parties created pursuant to this Agreement is, and is intended to be, that of independent contractors. Distributor will not by any action represent itself as having the authority to assume or create any obligation or liability on behalf of Producer. Distributor understands and acknowledges that its relationship with Producer is that of a buyer to a seller and that Distributor is not an agent, partner or franchisee of Producer. Distributor will purchase Products and resell them in Distributor’s own name, for Distributor’s own account, and at Distributor’s own risk. Under no circumstances will this Agreement be construed as appointing Distributor as a commercial or other agent of Producer pursuant to the laws of any country.

2. Distributor Responsibilities. The Distributor shall:

(a) Diligently sample, sell, advertise and promote the sale of the Products to the Industry in the Trading Area to fulfill the Products sales objectives mutually established by the parties from time to time;

(b) Maintain a bona fide sales department adequately staffed, trained and equipped to enable Distributor to serve the Industry in the Trading Area adequately and properly, to give customers technical sales assistance, address and resolve customer complaints and to fulfill its other obligations under this Agreement;

(c) Maintain adequate sales and warehouse facilities as well as a representative and adequate stock of the Products to meet the demands of the Industry in the Trading Area;

(d) Prepare and maintain, and submit to the Producer on a timely basis, all documentation and reports reasonably required from time to time to be prepared, maintained or submitted, including but not limited to, the following: customer, sales, freight and inventory data regarding the Products, pricing and volume data, and call reports regarding visits to existing and potential customers in the Trading Area, all in such form and at such times as Producer may from time to time reasonably request;

(e) Maintain adequate supply of all current literature (including product data sheets, safety data sheets (“SDS”), brochures, etc.) relating to the Products and to provide customers and prospective customers with copies of the same at the time of Product inquiry or sale and, in particular, maintain and provide all customers of Products with appropriate safety related literature and SDS in full compliance with all applicable regulatory requirements including, as applicable, the OSHA Hazard Communication Standard;

(f) Participate in trade shows and exhibitions in the Trading Area where, in Distributor’s reasonable business judgment, such participation will promote the Products;

(g) Not make any representation or warranty with respect to any Products, other than as expressly provided by Producer;

(h) Conduct its business in a professional and ethical manner, and in compliance with all applicable laws including, without limitation, those pertaining to taxes and the prohibition of corruption, bribery and the offering of inducements to public or semi-public officials, including the United States Foreign Corrupt Practices Act;

(i) In the event Distributor purchases any Products in bulk and then bags such material prior to sale to customers, Distributor shall (i) use bagging and packaging materials which will fully comply with any and all applicable laws and regulations including, as applicable, the OSHA Hazard Communication Standard; and (ii) only sell and distribute Products in bags or containers bearing a health warning which has either been: (A) approved in writing by Producer or (B) provided by Producer;

(j) Sell, advertise and promote the Products only to customers in the Industry within the Trading Area and promptly refer all orders for Products from outside the Trading Area, and any orders for Products from inside the Trading Area for use outside the Industry, in each case where Distributor is not authorized to sell such Products, to Producer or its nominee.

3. Producer’s Responsibilities.

(a) Provided Distributor is not in breach of any of its obligations under this Agreement, Producer shall (i) sell the Products to the Distributor as provided in this Agreement, and (ii) supply Distributor without charge with reasonable quantities of its regular promotional materials relating to the Products, including safety and technical data sheets, bulletins and such other data as Producer may from time to time have for promotional purposes.

(b) Producer shall conduct its business in a professional and ethical manner, and in compliance with all applicable laws including, without limitation, those pertaining to taxes and the prohibition of corruption, bribery and the offering of inducements to public or semi-public officials, including the United States Foreign Corrupt Practices Act.

4. Pricing.

(a) Except as otherwise agreed in writing between the parties, the initial price of each Product to be sold to Distributor under this Agreement for re-sale by Distributor shall be set at a price equal to 90% of the average sale price of such Product on the customer market over the 12 months prior to the Effective Date.

(b) Except as otherwise agreed in writing between the parties, at the start of each Contract Year, the price of each Product to be sold to Distributor under this Agreement for re-sale by Distributor shall be adjusted by the percentage increase or decrease in the average sales price of such Product sold by Distributor on the customer market (excluding, for the avoidance of doubt, any transportation costs) (“AMSP”) between the previous two contract years in accordance with the following formula:

Product price for Contract Year [x]


=	AMSP in Contract Year [x – 1]	X Product price in Contract Year [x – 1]
=	AMSP in Contract Year [x – 2]	X Product price in Contract Year [x – 1]

provided that, if the foregoing adjustment would result in a price increase or decrease of greater than 10% as a result of extraordinary market circumstances (for example, a temporary shortage of supply due to unforeseen circumstances), the parties shall negotiate in good faith an appropriate price adjustment that excludes, to the extent possible, the impact of such extraordinary market circumstance. If the parties are unable to agree on an appropriate price adjustment within 30 days, the price shall be adjusted in accordance with the foregoing formula. For purposes of the foregoing, each successive 12-month period during the Term (the first of which will commence on the Effective Date) is referred to as a “Contract Year”.

(c) Except as set forth in Exhibit B or C with respect to any particular Industry or Trading Area, all prices are net F.O.B. Producer’s plant or warehouse, as applicable (each, the “Producer Location”), and are exclusive of any sales, use, property, excise, occupation, import or export tax or other similar tax levied or that may be levied by any federal, state, governmental or other taxing authorities in connection with the sales of the Products, and any applicable transportation or other surcharges, all of which shall be paid by Distributor. Distributor shall bear the risk of loss or damage in transit after Products have been delivered to a transportation company for shipment to Distributor or any third party pursuant to Distributor’s instructions. Special packaging, if required, shall be priced extra. Delivery dates and shipment dates are estimates only and are not guaranteed.

(d) Distributor shall pay Producer for Products in US dollars in the full amount invoiced by Producer, without deduction or set-off of any kind. Payment shall be made net sixty (60) days after the date of shipment. Failure to pay an invoice by the due date, at Producer’s election, makes all subsequent invoices immediately due and payable, irrespective of terms. In the event of Distributor’s (i) insolvency, (ii) failure to pay an invoice by the due date or (iii) material breach of any of the terms of this Agreement, Producer shall have the right to stop delivery of the Products (including withholding deliveries under outstanding orders) until full payment is received or the breach is otherwise remedied.

5. Warranty.

(a) Producer warrants solely to Distributor only that (i) Products furnished hereunder shall conform to applicable specifications and (ii) Distributor shall acquire good and marketable title to the Products, and no other warranty shall be implied. Provided that Distributor gives notice in accordance with Section 5(b) below, if Products sold hereunder fail to conform to applicable specifications, demonstrated to Producer’s reasonable satisfaction to have existed at the time of departure from Producer’s plant, Producer, reserving the right to inspect Products, shall, at Producer’s option, replace at Producer’s expense F.O.B. Distributor’s plant or give Distributor credit for Products determined to be non-conforming. Producer shall not be obligated to replace or provide credit for Products that shall have been subjected to alteration, contamination, improper maintenance or storage, misapplication, misuse, negligence or accident during or after shipment from Producer’s plant. The remedy set forth in this Section 5(a) shall be the sole and exclusive remedy available to Distributor for breach of warranty. In no event shall Distributor’s remedy exceed the purchase price of the non-conforming Products, plus any transportation costs paid by Producer to supply replacement materials to Distributor as described above in this Section 5(a) and Producer shall not be liable for any other loss or damage, whether direct or indirect. THE WARRANTIES SET FORTH IN THIS SECTION 5 ARE THE ONLY WARRANTIES APPLICABLE TO THE PRODUCTS SOLD HEREUNDER. ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE SPECIFICALLY DISCLAIMED AND SHALL NOT APPLY. Distributor is solely responsible for determining suitability for use and Producer shall in no event be liable in this respect. The giving or failure to give advice, recommendation or safety warnings of any character by Producer shall not impose any liability upon Producer.

(b) It shall be the duty of Distributor to thoroughly inspect the Products purchased from Producer. Except for claims based on latent defects (which the parties recognize may not be discoverable through an inspection), all claims of any nature relating to the Products for any defect, non-conformity or discrepancy in quantity or delivery date, shall be made in writing to Producer’s customer service department within 30 days of receipt of such Products by Distributor. Failure to make any such written claim within the above-prescribed period shall constitute waiver of any such claims and shall be deemed acceptance of such materials, quantities or delivery dates.

(c) Neither party shall be liable to the other party for any special, incidental, consequential, indirect or punitive damages (including loss of (anticipated) profits) arising in any way out of this Agreement, however caused and on any theory of liability, except with respect to claims based on intentional fraud or intentional misconduct. For the avoidance of doubt, if any of the foregoing damages are awarded to a third party and a party has a right to bring a claim against the other party under this Agreement in respect of such third party claim, such damages will be considered direct damages.

6. Safety Warning and Handling.

(a) WARNING: RESIN COATED PROPPANTS – POSSIBLE DUST EXPLOSION HAZARD AND MAY CAUSE ALLERGIC SKIN REACTION. WARNING: FRACTURING SAND AND RESIN COATED PROPPANTS – MAY CAUSE DELAYED LUNG INJURY AND CANCER HAZARD. BOTH MATERIALS CONTAIN FREE CRYSTALLINE SILICA. DO NOT BREATHE DUST. PROLONGED INHALATION OF THE ABOVE AND OF AIRBORNE SILICA CONTAINED IN SILICA SAND, CRISTOBALITE AND MATERIALS CONTAINING SILICA CAN CAUSE DELAYED LUNG INJURY AND/OR RESPIRATORY DISEASE, INCLUDING SILICOSIS, A PROGRESSIVE DISABLING AND SOMETIMES FATAL LUNG DISEASE. THE INTERNATIONAL AGENCY FOR RESEARCH ON CANCER HAS DETERMINED THAT SILICA DUST (WHICH INCLUDES CRYSTALLINE AND MICROCRYSTALLINE SILICA), CRISTOBALITE DUST AND CRYSTALLINE SILICA INHALED FROM OCCUPATIONAL SOURCES CAN CAUSE CANCER IN HUMANS. AVOID CREATING DUST WHEN HANDLING, USING OR STORING. FOLLOW OSHA OR OTHER RELEVANT SAFETY AND HEALTH STANDARDS AND USE GOOD HOUSEKEEPING AND ADEQUATE VENTILATION TO KEEP EXPOSURE BELOW RECOMMENDED EXPOSURE LIMITS. AVOID PROLONGED OR REPEATED SKIN CONTACT. THE RISK OF LUNG DISEASE IS INCREASED IF SMOKING IS COMBINED WITH SILICA RESPIRATION. CURRENT SAFETY DATA SHEET IS AVAILABLE AND SHOULD BE CONSULTED BEFORE HANDLING THIS MATERIAL. PROPER RESPIRATORY PROTECTION, SILICA DUST PREVENTION AND APPLICABLE HEALTH AND SAFETY REGULATORY PROTOCOLS MUST BE STRICTLY OBSERVED AT ALL TIMES WHEN HANDLING MATERIALS SUPPLIED BY PRODUCER TO MINIMIZE RISK OF INJURY DUE TO INHALATION OF AIRBORNE SILICA. RESIN COATED PROPPANTS: UNLOADING OPERATIONS – DO NOT EXCEED 5 PSI WHEN UNLOADING THIS MATERIAL TO MINIMIZE THE CREATION OF AIRBORNE DUST AND POSSIBLE DUST EXPLOSION HAZARD.

(b) PRODUCER WILL NOT BE LIABLE TO DISTRIBUTOR FOR ANY HARMFUL HEALTH EFFECTS WHICH MAY BE CAUSED BY EXPOSURE TO MATERIALS SUPPLIED BY PRODUCER HEREUNDER. Distributor warrants that it will adequately warn all of its employees and customers who may come in contact with materials supplied by Producer of the above described health hazards. Further, Distributor warrants it will fully comply with all applicable health and safety regulations and orders relating to the workplace handling of Products supplied by Producer. Distributor agrees that if the Products supplied hereunder are resold by Distributor, Distributor will include in its contract for resale provisions which include the full substance of those contained in this Section 6, including the foregoing safety warning.

7. Producer Label, Products and Information. Distributor agrees that it will not remove from any Product purchased hereunder, or obliterate, any label, decal, trademark, product warning or instruction, patent or manufacturer’s lot numbers placed thereon by Producer.

8. Trademarks.

(a) The Distributor shall not use or register any trademark used by or registered in the name of Producer, or any affiliate of Producer (“Producer Trademarks”), or any word or trademark that is similar in sight, sound or meaning, or otherwise likely to be confused therewith, in any manner except as permitted by Producer in connection with the promotion, advertising, and sale of each of the Products. Distributor shall observe all applicable quality standards specified by Producer as to the manner of use of the Producer Trademarks applicable to each of the Products being distributed by Distributor in the packaging, labeling, promoting, advertising and/or selling of such Products by Distributor. On Producer’s request, all packaging, labels, promotional and advertising materials created by Distributor and containing any Producer Trademark, as well as the promotion of any of the Products with the applicable Producer Trademark by Distributor at any trade show, shall be subject to review and approval by Producer. Upon termination of this Agreement, Distributor shall cease immediately all use of the Producer Trademarks, and shall remove them or cause them to be removed from all signs, advertisements, letterheads, ▇▇▇▇ heads, forms, listings and any other things on which they may be used by the Distributor, and shall discontinue all representations from which it might be inferred that Distributor is an authorized distributor of any of the Products of Producer. The Distributor acknowledges Producer’s exclusive ownership of Producer Trademarks and acquires no right, title or interest in or to the Producer Trademarks hereunder.

(b) Producer hereby grants to the Distributor for the Term, and subject to the terms and conditions herein, a non-exclusive, non-transferable, revocable right to use the Producer Trademarks in connection with the marketing and promotion of the Products in the Trading Area in accordance with the terms and conditions of this Agreement and any guidelines issued by Producer from time to time. During the Term, Distributor shall have the right to indicate to the public that it is an authorized Distributor of the Products.

9. Product Changes. Producer reserves the right from time to time, in its absolute discretion, without incurring any liability to the Distributor with respect to any purchase order previously placed or inventory held by Distributor, or otherwise, to discontinue or to limit its

production or alter the specifications of any Product or Product line, to terminate or limit deliveries of any Product or Product line, the production of which is so discontinued, limited or altered, and to add new and additional products or product lines; provided, that, any new products or product lines shall first be offered to Distributor for exclusive resale in the Industry in the Trading Area pursuant to the terms and conditions set forth herein.

10. Term; Termination.

(a) This Agreement shall commence on the Effective Date and shall, unless earlier terminated pursuant to subsections (b) through (f) hereof, continue for a term of twenty (20) years following the Effective Date (“Term”).

(b) Producer may terminate this Agreement, effective upon written notice to Distributor, if Distributor’s annual sales volumes of Products by Industry or Trading Area fall below the Applicable Minimum for two consecutive calendar years during the Term; provided however that if Producer has supplied Product volumes less than 2016 levels in such year(s), Producer may only terminate if Distributor failed to sell at least 80% of the Product supply made available by Producer to Distributor in such year(s). For purposes of this Agreement, “Applicable Minimum” means the amount set forth on Exhibit B with respect to each Industry or on Exhibit C with respect to each Trading Area, as the context requires.

(c) Producer may terminate this Agreement, effective upon written notice to Distributor, if Distributor: (i) fails to make any payment called for under this Agreement by the date falling ten (10) days after the due date, and such failure has continued for twenty (20) or more days after Distributor receives written notice from Producer specifying the failure to pay by such date; (ii) breaches any of its obligations or restrictions in Section 2(h), 2(j), 7 or 8; or (iii) for any reason, suffers the loss of any license or permit required by law that is necessary for Distributor to carry out any of its obligations under this Agreement, and such loss has continued for thirty (30) or more days.

(d) Either party may terminate this Agreement, effective upon written notice to the other party (i) if such other party fails to observe or perform any of its obligations in this Agreement (other than those obligations addressed in Section 10(b) or 10(c)), and such failure has continued for thirty (30) or more days after such party receives written notice from the other party specifying the nature of the alleged breach; (ii) if such other party voluntarily commences any proceeding or files a petition seeking liquidation, reorganization or other relief under any bankruptcy, receivership or similar law; or (iii) if an involuntary proceeding is commenced or petition is filed against such other party seeking liquidation, reorganization or other relief in respect of such party under any bankruptcy, receivership or similar law, and such proceeding or petition is not dismissed within sixty (60) days after first initiated.

(e) This Agreement, and all obligations, terms and conditions contained herein, shall automatically terminate without any further action required by any party upon [Producer][Distributor], directly or indirectly, ceasing to own more than 50% of the issued and outstanding shares of common stock of [Producer][Distributor].¹

(f) Notwithstanding anything to the contrary in this Agreement, if a termination is based on Section 10(b), 10(c) or 10(d) and the circumstance giving rise to such termination is attributable to only a particular Industry or jurisdiction of the Trading Area, then the termination may only apply to such particular Industry or jurisdiction. If this Agreement is only terminated in part, it will continue in full force and effect with respect to the remaining Industry(ies) and jurisdictions of the Trading Area.

11. Rights on Termination. Termination of this Agreement shall not affect any right of Producer or Distributor that shall have arisen prior to such termination, except that:

(a) Producer thereafter has the right, but shall be under no obligation, to deliver to Distributor any Product for which it may have accepted an order from Distributor, whether such order was scheduled for delivery prior to the date of such termination or subsequent thereto, but Distributor agrees to immediately pay the agreed price for said Products if delivered.

(b) In the event that Producer shall determine not to deliver to Distributor, Distributor may, or at Producer’s option shall, assign any unfilled customers’ orders on hand at time of termination for the Products to Producer and Producer will ship and ▇▇▇▇ the customer directly, provided that customer’s credit is satisfactory to Producer. On such orders Producer will pay Distributor a selling commission of 5% of Distributor’s quoted price to the customer for such Products . No further orders beyond those on hand at termination would be handled in this manner.

(c) Producer has the right, but shall be under no obligation, to take back or transfer to another distributor any of the Products which Distributor has not sold within one hundred twenty (120) days from the date of termination and wishes to return to Producer. If such returned Products are unused, undamaged and in a salable condition, as reasonably determined by Producer, Producer will repay to Distributor an amount equal to Distributor’s reasonably substantiated Laid In Cost therefore. Appropriate adjustments will be made in the case of used or damaged goods. For purposes of this Agreement, “Laid-In Cost” means the sum of (i) the price paid by Distributor to Producer for such inventory, plus (ii) any sales, use, property, excise, occupation, import or export tax or other non-refundable or non-creditable taxes paid by Distributor (excluding income tax) for such inventory, plus (iii) the cost of freight, insurance, warehouse handling, and any other direct expenses paid by Distributor related to the movement of such inventory from the Producer Location to Distributor’s warehouse or distribution center.

(d) All promotional literature, data sheets, sales aids, and other similar materials or effects which the Producer may have furnished to the Distributor in connection with its activities hereunder, will be returned immediately upon notice of termination. Such material

will be shipped to Producer to any location selected by Producer within the Trading Area. Distributor shall cease immediately upon termination of this Agreement any activity which could reasonably be understood as Distributor representing that it is a Producer distributor.

12. Indemnification.

(a) Subject to Sections 5 and 13, Distributor will indemnify, defend and hold Producer harmless from and against any and all claims and demands in each case made by third parties and all resulting liabilities, obligations, costs, losses and expenses, including court or arbitration costs and reasonable attorneys’ and experts’ fees, that Producer may suffer to the extent resulting from or arising out of: (i) any breach by Distributor (or any sub-distributor) of any of its obligations or any of its representations or warranties contained in this Agreement; (ii) any unauthorized act of Distributor, its sub-distributors, or any of their agents or employees; (iii) the negligent acts or omissions or willful misconduct of Distributor or its sub-distributors; or (iv) the relationship between Distributor and any of its sub-distributors (even if approved in accordance with Section 1(a)), or the termination thereof. At Producer’s election, in its sole discretion, Distributor will take reasonable steps to defend Producer with respect to any claim by a third party that is subject to the foregoing indemnity obligation in any action, suit or other proceeding and select counsel that is reasonably satisfactory to Producer, and Producer may participate in (at Producer’s expense) all aspects of, any such proceeding, including any settlement thereof (subject to Section 12(b)). Where Producer elects to defend the claim, Distributor may participate (at its expense) in all aspects of any proceeding, including any settlement of the claim (subject to Section 12(b)).

(b) The indemnified party will provide prompt written notice of a claim to the indemnifying party; provided that the failure of any indemnified party to give notice will not relieve the indemnifying party of its obligations under this Section 12, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. The indemnifying party agrees to timely reimburse the indemnified party for expenses incurred in connection with a claim for which the indemnified party is entitled to indemnification under this Section 12. The party that has assumed the defense of any claim pursuant to Section 12(a) may not settle the claim without the written consent of the other party unless (i) the terms of such settlement do not impose any obligations or restrictions on the indemnified party, (ii) the full amount of any monetary settlement is paid by the indemnifying party, and (iii) the indemnified party receives as part of such settlement a legal, binding and enforceable unconditional release providing that such third party claim and any claimed liability of the indemnified party with respect to the third party claim is fully satisfied by reason of such settlement and that the indemnified party is being released from any and all obligations and liabilities it may have with respect to the third party claim.

13. Limitations on Liability. Neither Producer nor the Distributor shall, by reason of the termination or non-renewal of the Distributor’s distributorship of the Products, be liable to the other for any indemnification, compensation, reimbursement or damages on account of the loss of prospective profits on anticipated sales, or on account of expenditures, investments, leases or commitments in connection with the business or goodwill of Producer or the Distributor, or otherwise. Irrespective of whether such obligations or liabilities may be

contemplated in the laws of the Trading Area or elsewhere, both parties hereby waive any rights (if any) each may have to such indemnification, compensation, reimbursement and damages in the event of the termination or non-renewal of the Distributor’s distributorship of the Products.

14. Notice. Except for purchase orders and invoices, which may be sent by e-mail or such other written means as the parties may agree from time to time, all notices to be given hereunder shall be deemed sufficient if in writing and sent to the addresses set forth below, or to such other addresses as may be subsequently designated by the parties in the manner provided herein, by registered or certified mail, return receipt requested, postage prepaid, or by nationally recognized overnight courier service: ³

15. Excusable Non-Performance. A party shall not be liable for failure to perform any part of this Agreement, except for the payment of money (which obligation is not affected by this Section 15), to the extent and duration that such failure to perform is on account of Acts of God or any government, fire, strike, labor dispute, accident, war, insurrection, embargoes, delays of carriers or suppliers, or for any other causes beyond such party’s reasonable control or without its fault (“Force Majeure”). In the case of any delay or failure that either party anticipates will cause an excusable delay hereunder, such party will, within ten (10) days of becoming aware of such delay or failure, give the other party written notice thereof, including a description of the steps (if any) such party is taking to alleviate the underlying issue.

16. General.

(a) This Agreement, including the attached Exhibits, which are incorporated herein, contains the entire agreement and understanding between Producer and Distributor with respect to the distribution of the Products and supersedes and replaces all prior agreements and understandings, oral or written, with respect to the same. Except as otherwise expressly provided in this Agreement, this Agreement shall not be amended or modified except by a written instrument signed by both Producer and Distributor. It is recognized that Distributor may from time to time issue a purchase order or other similar transactional form or document, and that, other than with respect to the identification of specific quantities of Product being ordered from Producer, any terms and conditions contained on such forms and documents shall be of no force and effect, and shall not constitute a modification or amendment of this Agreement absent Producer’s specific, written agreement.

(b) This Agreement shall be binding upon and inure to the benefit of the parties and their respective legal representatives and permitted successors and assigns. Neither party may assign this Agreement without the other party’s prior written consent, such consent not to be unreasonably withheld, conditioned or delayed.

(c) This Agreement shall be governed by and construed in accordance with the laws of the State of New York, not including the 1980 United Nations Convention for the International Sale of Goods and notwithstanding the principles, if any, that would otherwise govern the choice of applicable law. Each party agrees that any and all litigation it may initiate arising out of the interpretation, enforcement or breach of any provision of this Agreement shall be brought in the State of New York in any court having competent subject matter jurisdiction over such dispute. Additionally, each party hereby submits itself to the jurisdiction of any court in the State of New York having competent subject matter jurisdiction.

(d) The failure of either party to require the performance of any term or obligation of this Agreement, or the waiver of either party of any breach of this Agreement, shall not prevent a subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.

(e) The section headings used in this Agreement are for reference purposes only, and shall not affect the interpretation of this Agreement.

(d) The terms of Sections 4(b), 5, 7, 8, 11, 12, 13, 15, 17 and this Section 16 (each to the extent applicable after the Term) will survive the expiration or termination of this Agreement for any reason.

EXCLUSIVE AGENCY AGREEMENT

THIS EXCLUSIVE AGENCY AGREEMENT (this “Agreement”), is dated as of [●], (the “Effective Date”), by and between Unimin Corporation, a Delaware corporation [(“Producer”)][(“Agent”)] and SCR-Sibelco NV, a Belgian public company [(“Producer”)][(“Agent”)].

WHEREAS, Producer seeks to have Agent serve as its exclusive agent to promote, market and solicit orders for Producer’s Products from customers in the Industries and within the Trading Areas, each as defined below, under the terms and conditions set forth herein; and

WHEREAS, Agent seeks to promote, market and solicit orders for the sale of the Products to customers in the Industries within the Trading Areas, and in accordance with the terms set forth herein;

NOW, THEREFORE, in consideration of the mutual covenants and provisions herein contained, and other good and valuable consideration, the receipt and sufficiency of which is acknowledged by the parties hereto the parties agree as follows:

1. Appointment of Sales Agent.

(a) Subject to the provisions of this Agreement, Producer hereby appoints Agent and Agent hereby accepts appointment as the Producer’s exclusive sales agent for the Producer materials listed on the attached Exhibit A (“Products”) for the Industries listed on attached Exhibit B (each, an “Industry”) within the geographical area listed on attached Exhibit C (the “Trading Area”), and Agent hereby accepts such appointment. Agent shall have the right to solicit orders for Products only from persons and entities in the Industries and having their places of business within the Trading Area. Agent shall be the exclusive agent for the Producer for sale of Products in the Trading Area for the term of this Agreement. Except as specifically provided herein to the contrary, any sale of Products in the Industries in the Trading Area shall be credited as sales made by Agent and Agent shall be entitled to the commission provided herein. The provisions of this Agreement constitute the entire agreement and understanding between the parties on the subject matter of this Agreement, and except as specifically set forth herein, there are no additional agreements, understandings, representations, covenants, warranties or guaranties, written or oral, between the parties, relating to the subject matter of the Agreement. Prior arrangements, agreements and understandings, if any, are superseded by this Agreement. Agent may appoint any third party to act as a sub-agent, upon obtaining Producer’s prior written consent, which consent shall not be unreasonably withheld, delayed or conditioned.

(b) The relationship of the parties created pursuant to this Agreement is, and is intended to be, that of independent contractors. Agent will not by any action represent itself as having the authority to assume or create any obligation or liability on behalf of Producer.

2. Agent Responsibilities. The Agent shall:

(a) Diligently sample, advertise and promote the sale of the Products to the Industry in the Trading Area to fulfill the Products sales objectives mutually established by the parties from time to time;

(b) Maintain a bona fide sales department adequately staffed, trained and equipped to enable Agent to serve the Industry in the Trading Area adequately and properly, to give customers technical sales assistance, address and resolve customer complaints and to fulfill its other obligations under this Agreement;

(c) Prepare and maintain, and submit to the Producer on a timely basis, all documentation and reports reasonably required from time to time to be prepared, maintained or submitted, all in such form and at such times as Producer may from time to time reasonably request;

(d) Maintain adequate supply of all current literature (including product data sheets, safety data sheets (“SDS”), brochures, etc.) relating to the Products and to provide customers and prospective customers with copies of the same at the time of Product inquiry or order solicitation, acceptance or thereafter, and, in particular, maintain and provide all customers of Products with appropriate safety related literature and SDS in full compliance with all applicable regulatory requirements including, as applicable, the OSHA Hazard Communication Standard;

(e) Participate in trade shows and exhibitions in the Trading Area where, in Agent’s reasonable business judgment, such participation will promote the Products;

(f) Not make any representation or warranty with respect to any Products, other than as expressly provided by Producer;

(g) Conduct its business in a professional and ethical manner, and in compliance with all applicable laws including, without limitation, those pertaining to taxes and the prohibition of corruption, bribery and the offering of inducements to public or semi-public officials, including the United States Foreign Corrupt Practices Act;

(h) Not promote, market or solicit orders for any Products outside the Trading Area, or inside the Trading Area for use outside the Industries, in each case where Agent is not authorized to sell such Products, without Producer’s prior written consent, which consent may be withheld in Producer’s absolute discretion; and,

(i) Sell, advertise and promote the Products only to customers in the Industry within the Trading Area and promptly refer all orders for Products from outside the Trading Area, and any orders for Products from inside the Trading Area for use outside the Industry, in each case where Agent is not authorized to sell such Products, to Producer or its nominee.

3. Producer’s Responsibilities.

(a) Provided Agent is not in breach of any of its obligations under this Agreement, Producer shall: (i) supply Agent, without charge, with reasonable quantities of its regular promotional materials relating to the Products, including safety and technical data sheets, bulletins and such other data as Producer may from time to time have for promotional purposes; and (ii) provide Agent with reasonable technical assistance.

4. Quotations, Orders and Payment by Industry Customers.

(a) Agent will make quotations in respect to the sales of the Products only in accordance with the Producer’s then current policies and procedures, on prices agreed between the parties in advance and on the Producer’s terms and conditions of sale, including the terms of payment specified by the Producer. The Agent will assist the Producer in obtaining the appropriate documentation needed for Industry customers (for example, credit reports, sales tax exemptions, etc.).

(b) Orders for sales generated by Agent may be submitted to the Producer either by the Agent or the Industry customer. If Agent receives any order for Products, it will promptly forward it to the Producer. The Producer will establish and promulgate the criteria for sales orders to be generated by Agent and Agent will use its commercially reasonable efforts to secure sales orders that meet the Producer’s criteria. The Producer will have the right at any time to reject any order in whole or in part for good cause. Good cause shall include the following: (i) the sales order fails to meet the Producer’s criteria, (ii) the Industry customer fails to meet the Producer’s credit criteria, (iii) lack of Product availability due to no fault of the Producer, or (iv) poor payment history by the Industry customer.

(c) The Producer will ▇▇▇▇ the Industry customer for the purchased Products. Agent will not ▇▇▇▇ Industry customers for the Products unless expressly requested to do so by the Producer in writing. Payments against purchase orders are to be made directly to the Producer, without intervention by Agent unless expressly requested in writing by the Producer in each instance. If Agent receives any payment from an Industry customer, Agent will immediately forward the entire amount of such payment to the Producer.

(d) Producer will have the right, in its sole discretion, to issue credits, make discounts and allowances, and/or accept returns of the Products.

5. Commissions.

(a) The Producer shall pay to the Agent, as compensation for its services during the Term, a commission of five percent (5%) of Net Sales of Products generated by Agent to the Industries in the Trading Area for which payment is received by Producer from any Industry customer. Payment of commission shall be made by the Producer to Agent on or before 45 days following the calendar quarter of receipt by Producer of payment for Products from its Industry customers. At the time of payment of commission, the Producer shall furnish the Agent with an itemized statement setting forth the computation of commissions. For purposes of this Agreement, Net Sales means gross sales of Products by Agent in the Trading Area less: (i) transportation costs; (ii) replacement costs; (iii) rebates; (iv) warehouse, terminal and handling costs and (v) import and export fees.

(b) In the event of termination of this Agreement for any reason, the Producer shall be obligated to pay commissions only with respect to purchase orders for Products procured from Industry customers in the Trading Area prior to termination of this Agreement and subsequently accepted by the Producer and for which Producer has received payment from the applicable Industry customer. Any adjustments which may be required pursuant to Section 5(c) hereof shall be made notwithstanding any termination of this Agreement.

(c) Notwithstanding anything to the contrary set forth above, there shall be deducted from any commissions due the Agent an amount equal to: (i) commissions previously paid or credited to the Agent for sales of Products which are thereafter returned by the Industry customer; and (ii) the applicable portion of commissions previously paid or credited to the Agent for sales of Products as to which any allowance or adjustment is credited to the Industry customer for any reason.

(d) The Agent and the Producer will agree on an acceptable quarterly expense level for the Agent. The Producer will pay the agreed upon amount to the Agent in advance at the beginning of each calendar quarter following receipt of a proper invoice. Any additional expenditures or extraordinary expenses must be approved in advance by the Producer in order to be reimbursed.

6. Trademarks.

(a) The Agent shall not use or register any trademark used by or registered in the name of Producer, or any affiliate of Producer, (“Producer Trademarks”), or any word or trademark that is similar in sight, sound or meaning, or otherwise likely to be confused therewith, in any manner except as permitted by Producer in connection with the promotion, advertising, and sale of each of the Products. Agent shall observe all applicable quality standards specified by Producer as to the manner of use of the Producer Trademarks applicable to each of the Products being distributed by Agent in the packaging, labeling, promoting, advertising and/or selling of such Products by Agent. On Producer’s request, all packaging, labels, promotional and advertising materials created by Agent and containing any Producer Trademark, as well as the promotion of any of the Products with the applicable Producer Trademark by Agent at any trade show, shall be subject to review and approval by Producer. Upon termination of this Agreement, Agent shall cease immediately all use of the Producer Trademarks, and shall remove them or cause them to be removed from all signs, advertisements, letterheads, ▇▇▇▇ heads, forms, listings and any other things on which they may be used by the Agent, and shall discontinue all representations from which it might be inferred that Agent is an authorized Agent of any of the Products of Producer. The Agent acknowledges Producer’s exclusive ownership of Producer Trademarks and acquires no right, title or interest in or to the Producer Trademarks hereunder.

(b) Producer hereby grants to the Agent for the Term, and subject to the terms and conditions herein, a non-exclusive, non-transferable, revocable right to use the Producer Trademarks in connection with the marketing and promotion of the Products in the Trading Area in accordance with the terms and conditions of this Agreement and any guidelines issued by Producer from time to time. During the Term, Agent shall have the right to indicate to the public that it is an authorized Agent of the Products.

7. Product Changes. Producer reserves the right from time to time, in its absolute discretion, without incurring any liability to the Agent with respect to any purchase order previously placed or inventory held by Agent, or otherwise, to discontinue or to limit its production or alter the specifications of any Product or Product line, to terminate or limit deliveries of any Product or Product line, the production of which is so discontinued, limited or altered, and to add new and additional products or product lines; provided, that, any new products or product lines shall first be offered to Agent for exclusive agency rights in the Industry in the Trading Area pursuant to the terms and conditions set forth herein.

8. Term; Termination

(a) This Agreement shall commence on the Effective Date and shall, unless earlier terminated pursuant to subsections (b) through (e) hereof, continue for a term of twenty (20) years following the Effective Date (“Term”).

(b) Producer may terminate this Agreement, effective upon written notice to Agent, if Agent’s annual volume of orders generated of Products by Industry or Trading Area fall below the Applicable Minimum for two consecutive calendar years during the Term; provided however that if Producer has made available Product volumes less than 2016 levels in such year(s), Producer may only terminate if Agent failed to generate orders for at least 80% of the Product supply made available by Producer to Agent in such year(s). For the purposes of this Agreement, “Applicable Minimum” means the amount set forth on Exhibit B with respect to each Industry or on Exhibit C with respect to each Trading Area, as the context requires.

(c) Agent may terminate this Agreement, effective upon written notice to Producer, if Producer fails to make any payment called for under this Agreement by the date falling ten (10) days after the due date, and such failure has continued for twenty (20) or more days after Producer receives written notice from Agent specifying the failure to pay by such date.

(d) Producer may terminate this Agreement, effective upon written notice to Agent, if Agent: (i) breaches any of its obligations or restrictions in Section 2(g), 2(i), 2(h) or 6; or (ii) for any reason, suffers the loss of any license or permit required by law that is necessary for Agent to carry out any of its obligations under this Agreement, and such loss has continued for thirty (30) or more days.

(e) Either party may terminate this Agreement, effective upon written notice to the other party (i) if such other party fails to observe or perform any of its obligations in this Agreement (other than those obligations addressed in Section 8(b) or 8(c)), and such failure has continued for thirty (30) or more days after such party receives written notice from the other party specifying the nature of the alleged breach; (ii) if such other party voluntarily commences any proceeding or files a petition seeking liquidation, reorganization or other relief under any bankruptcy, receivership or similar law; or (iii) if an involuntary proceeding is commenced or petition is filed against such other party seeking liquidation, reorganization or other relief in respect of such party under any bankruptcy, receivership or similar law, and such proceeding or petition is not dismissed within sixty (60) days after first initiated.

(f) This Agreement, and all obligations, terms and conditions contained herein, shall automatically terminate without any further action required by any party upon [Producer][Agent], directly or indirectly, ceasing to own more than 50% of the issued and outstanding shares of common stock of [Producer][Agent].¹

(g) Notwithstanding anything to the contrary in this Agreement, if a termination is based on Section 8(b), 8(c) or 8(d) and the circumstance giving rise to such termination is

¹	Note to draft: Select appropriate parties for execution version.

attributable to only a particular Industry or jurisdiction of the Trading Area, then the termination may only apply to such particular Industry or jurisdiction. If this Agreement is only terminated in part, it will continue in full force and effect with respect to the remaining Industry(ies) and jurisdictions of the Trading Area.

9. Rights on Termination. Upon termination of this Agreement, the Agent shall cease all marketing and promotion of, and the solicitation of purchase orders for, the Products and promptly return to the Producer all promotional literature, data sheets, sales aids and other similar materials or effects which the Producer may have furnished to the Agent in connection with its activities hereunder. Upon any termination of this Agreement, the Producer shall not be liable to the Agent for loss of future commissions, goodwill, investments, advertising or promotional costs or like expenses. Neither Producer nor the Agent shall, by reason of the termination or non-renewal of the Agent’s agency, be liable to the other for any indemnification, compensation, reimbursement or damages on account of the loss of prospective profits on anticipated sales, or on account of expenditures, investments, leases or commitments in connection with the business or goodwill of Producer or the Agent, or otherwise. Irrespective of whether such obligations or liabilities may be contemplated in the laws of the Trading Area or elsewhere, both parties hereby waive any rights (if any) each may have to such indemnification, compensation, reimbursement and damages in the event of the termination or nonrenewal of the Agent’s agency.

10. Indemnification.

(a) Subject to Section 11, Agent will indemnify, defend and hold Producer harmless from and against any and all claims and demands in each case made by third parties and all resulting liabilities, obligations, costs, losses and expenses, including court or arbitration costs and reasonable attorneys’ and experts’ fees, that Producer may suffer to the extent resulting from or arising out of: (i) any breach by Agent (or any sub-agent) of any of its obligations or any of its representations or warranties contained in this Agreement; (ii) any unauthorized act of Agent, its sub-agent, or any of their agents or employees; (iii) the negligent acts or omissions or willful misconduct of Agent or its sub-agents; or (iv) the relationship between Agent and any of its sub-agents (even if approved in accordance with Section 1(a)), or the termination thereof. At Producer’s election, in its sole discretion, Agent will take reasonable steps to defend Producer with respect to any claim by a third party that is subject to the foregoing indemnity obligation in any action, suit or other proceeding and select counsel that is reasonably satisfactory to Producer, and Producer may participate in (at Producer’s expense) all aspects of, any such proceeding, including any settlement thereof (subject to Section 10(b)). Where Producer elects to defend the claim, Agent may participate (at its expense) in all aspects of any proceeding, including any settlement of the claim (subject to Section 10(b)).

party unless (i) the terms of such settlement do not impose any obligations or restrictions on the indemnified party, (ii) the full amount of any monetary settlement is paid by the indemnifying party, and (iii) the indemnified party receives as part of such settlement a legal, binding and enforceable unconditional release providing that such third party claim and any claimed liability of the indemnified party with respect to the third party claim is fully satisfied by reason of such settlement and that the indemnified party is being released from any and all obligations and liabilities it may have with respect to the third party claim.

11. Limitations on Liability. Neither Producer nor the Agent shall, by reason of the termination or non-renewal of the Agent’s agency be liable to the other for any indemnification, compensation, reimbursement or damages on account of the loss of prospective profits on anticipated sales, or on account of expenditures, investments, leases or commitments in connection with the business or goodwill of Producer or the Agent, or otherwise. Irrespective of whether such obligations or liabilities may be contemplated in the laws of the Trading Area or elsewhere, both parties hereby waive any rights (if any) each may have to such indemnification, compensation, reimbursement and damages in the event of the termination or non-renewal of the Agent’s agency. Neither party shall be liable to the other party for any special, incidental, consequential, indirect or punitive damages (including loss of (anticipated) profits) arising in any way out of this Agreement, however caused and on any theory of liability, except with respect to claims based on intentional fraud or intentional misconduct.

13. Excusable Non-Performance. A party shall not be liable for failure to perform any part of this Agreement, except for the payment of money (which obligation is not affected by this Section 13), to the extent and duration that such failure to perform is on account of Acts of God or any government, fire, strike, labor dispute, accident, war, insurrection, embargoes, delays of carriers or suppliers, or for any other causes beyond such party’s reasonable control or without its fault (“Force Majeure”). In the case of any delay or failure that either party anticipates will cause an excusable delay hereunder, such party will, within ten (10) days of becoming aware of such delay or failure, give the other party written notice thereof, including a description of the steps (if any) such party is taking to alleviate the underlying issue.

14. General.

(a) This Agreement, including the attached Exhibits, which are incorporated herein, contains the entire agreement and understanding between Producer and Agent with respect to the Agent’s agency and supersedes and replaces all prior agreements and understandings, oral or written, with respect to the same. Except as otherwise expressly provided in this Agreement, this Agreement shall not be amended or modified except by a written instrument signed by both Producer and Agent. It is recognized that Agent may from time to time issue transactional forms or documents, and that any terms and conditions contained on such forms and documents shall be of no force and effect, and shall not constitute a modification or amendment of this Agreement absent Producer’s specific, written agreement.

(b) This Agreement shall be binding upon and inure to the benefit of the parties and their respective legal representatives and permitted successors and assigns. The rights and obligations of Agent hereunder may not be assigned, delegated, or transferred without the prior written consent of Producer, and any attempted assignment, delegation or transfer in violation of this provision shall be void and automatically terminate this Agreement.

(f) The terms of Sections 6, 9, 10, 11, 12, 13, 15 and this Section 14 (each to the extent applicable after the Term) will survive the expiration or termination of this Agreement for any reason.

15. Interpretation. When a reference is made in this Agreement to an Article, Section or Exhibit, such reference shall be to an Article or Section of, or an Exhibit to, this Agreement, unless otherwise indicated. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The term “or” is not exclusive. The word “extent” in the phrase “to the extent” shall mean the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” All terms defined in this Agreement shall have the defined meanings when used in any certificate or other document made or delivered pursuant hereto unless otherwise defined therein.

WHEREAS, Sibelco, Unimin, Bison Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of Unimin (Merger Sub), Bison Merger Sub I, LLC (Merger Sub LLC), a Delaware limited liability company and wholly-owned subsidiary of Unimin, and Fairmount Santrol Holdings, Inc., a Delaware corporation (Fairmount), have entered into an Agreement and Plan of Merger, dated as of December 11, 2017 (the Merger Agreement), providing for, among other things and subject to the terms and conditions of the Merger Agreement: (i) the merger of Merger Sub with and into Fairmount (the Merger), with Fairmount surviving the Merger as a wholly-owned subsidiary of Unimin; and (ii) a further merger of Fairmount with and into Merger Sub LLC (the Second Merger and, together with the Merger, the Mergers), with Merger Sub LLC surviving the Second Merger as a wholly-owned subsidiary of Unimin.

WHEREAS, on or about the date hereof, Unimin and Sibelco (or certain of their controlled Affiliates) will enter into the Distribution Agreement and the Agency Agreement.

WHEREAS, in connection with, and as an inducement to the willingness of the Parties to consummate, the Mergers and consistent with the Merger Agreement, the Parties wish to enter into this Agreement.

NOW, THEREFORE, in consideration of the covenants and agreements set forth in this Agreement and for other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the Parties agree as follows:

ARTICLE I

ACTIVITIES

Section 1.1 Unimin/Fairmount Activities

(a)	The Parties each agree that Unimin and its controlled Affiliates may:

(i)

sell, market or distribute: (A) silica sand, calcium carbonate, lime, feldspathics, clay (including ball clay and kaolin), nepheline, coated materials, phenolic resins and coated materials, and Black Lab materials and services, or other energy focused minerals (including API Barite and API Bentonite) (the Unimin/Fairmount Products); (B) recycled materials (other than recycled glass or as otherwise agreed between the parties); or (C) any product that is not a Unimin/Fairmount Product ((B) and (C) being the Sibelco Products) to customers in the energy, foundry, glass, construction and building, sports and recreation, retail and DIY, biomass, ceramics, chemicals and agriculture industries (the Unimin/Fairmount Markets) in any of the United States of America and its overseas territories, Canada or Mexico (the Unimin/Fairmount Territories);

(ii)

sell, market or distribute the Unimin/Fairmount Products to customers in the energy market anywhere in the world;

(iii)

sell, market or distribute silica sand and coated silica sand to customers in the water treatment market in the Unimin/Fairmount Territories;

(vi)

sell, market or distribute Black Lab products in existing markets as of the Effective Time; and

produce any Unimin/Fairmount Products in any of the Unimin/Fairmount Territories.

(b)

For so long as Sibelco, together with its controlled Affiliates, owns more than 50% of the issued and outstanding shares of common stock of Unimin (the Restricted Period), and except as provided in Article II, Unimin will not, and will cause its controlled Affiliates not to, directly or indirectly, whether as principal, partner, officer, director, stockholder or otherwise, alone or in association with any other person, own, manage, operate, control, participate in, acquire (or have the right to acquire) voting securities of, perform services for, or otherwise carry on, any business involved with any activities other than those set out in Section 1.1(a) above; provided, however, that nothing in this Section 1.1(b) shall be deemed to limit in any way the activities of Unimin or its controlled Affiliates pursuant to, and in accordance with, the Distribution Agreement or the Agency Agreement (each as may be amended and/or restated from time to time), or any joint venture, joint development or other agreement entered into following the date hereof between Sibelco (or a controlled Affiliate thereof), on the one hand, and Unimin (or a controlled Affiliate thereof), on the other hand.

Section 1.2 Sibelco Activities

(a)	The Parties each agree that Sibelco and its controlled Affiliates may:

(i)

sell, market or distribute the Unimin/Fairmount Products or Sibelco Products to customers in the Unimin/Fairmount Markets (other than the energy market) anywhere outside of the Unimin/Fairmount Territories;

(iv)

produce the Sibelco Products or provide any services anywhere in the world.

(b)

During the Restricted Period, and except as provided in Article II, Sibelco will not, and will cause its controlled Affiliates (other than Unimin and its controlled Affiliates) not to, directly or indirectly, whether as principal, partner, officer, director, stockholder or otherwise, alone or in association with any other person, own, manage, operate, control, participate in, acquire (or have the right to acquire) voting securities of, perform services for, or otherwise carry on, any business involved with any activities other than those set out in Section 1.2(a) above provided, however, that nothing in this Section 1.2 shall be deemed to limit in any way the activities of Sibelco or its controlled Affiliates pursuant to, and in accordance with, the Distribution Agreement or the Agency Agreement (each as may be amended and/or restated from time to time), or any joint venture, joint development or other agreement entered into following the date hereof between Sibelco (or a controlled Affiliate thereof), on the one hand, and Unimin (or a controlled Affiliate thereof), on the other hand.

Section 1.3 Reasonableness of Restrictions

(a)

The Parties each acknowledge and agree that the covenants contained in this Article I are a material and substantial part of the transactions contemplated by the Mergers and are entered into in connection with, and as an inducement to, the willingness of the Parties to consummate the Mergers and enter into the Distribution Agreement and the Agency Agreement.

(b)	The Parties acknowledge and agree that the terms of the covenants in this Article I are fair and reasonable in light of the furtherance of the Mergers and the transactions contemplated by the Distribution Agreement and the Agency Agreement.

(c)

In the event that any of the covenants contained in this Article I shall be determined by any court of competent jurisdiction to be unenforceable for any reason whatsoever, then any such provision or provisions shall not be deemed void, and the Parties hereto agree that said limits may be modified by the court and that said covenant(s) contained in this Article I will be amended in accordance with said modification, it being specifically agreed by the Parties that it is their continuing desire that these covenants be enforced to the full extent of their terms and conditions or if a court finds the scope of the covenant(s) unenforceable, the court should redefine the covenant(s) so as to comply with Applicable Law.

ARTICLE II

CORPORATE OPPORTUNITIES; RIGHT OF FIRST OFFER

(a)	The Parties each agree that Unimin and its controlled Affiliates may pursue acquisitions or investment opportunities with respect to the production of:

(i)

Unimin/Fairmount Products in the Unimin/Fairmount Territories,

(ii)

coated products for customers in the energy market outside of the Unimin/Fairmount Territories,

(iii)

subject to paragraph (c) below, raw frac sand outside of the Unimin/Fairmount Territories, and

(iv)

subject to paragraph (c) below, any mineral that is not a Unimin/Fairmount Product in the Unimin/Fairmount Territories.

(b)	The Parties each acknowledge and agree that Sibelco and its controlled Affiliates may pursue any acquisitions or investment opportunities except for those referred to in paragraph (a)(i) and (ii) above.

(c)

If, during the Restricted Period, Unimin or any of its controlled Affiliates wishes to pursue any acquisition or investment opportunity with respect to the production of: (i) raw frac sand outside of the Unimin/Fairmount Territories, or (ii) any mineral that is not a Unimin/Fairmount Product in the Unimin/Fairmount Territories (each a ROFO Opportunity), Unimin will first serve a written notice (an Opportunity Notice) on Sibelco offering Sibelco (or a controlled Affiliate thereof) the right to pursue such ROFO Opportunity. The offer set out in an Opportunity Notice will remain open for acceptance by Sibelco for a period of 30 Business Days following service of such notice.

(d)	Unimin (or a controlled Affiliate thereof) may not pursue a ROFO Opportunity unless Unimin has served an Opportunity Notice on Sibelco in accordance with Article II(c) and Sibelco has elected in writing not to pursue such ROFO Opportunity as set out in the applicable Opportunity Notice.

ARTICLE III

MISCELLANEOUS

Section 3.1 Termination of this Agreement

This Agreement, and all obligations, terms and conditions contained herein, shall automatically terminate without any further action required by any Party upon either (i) the termination of the Merger Agreement in accordance with its terms, or (ii) Sibelco, together with its controlled Affiliates, ceasing to own more than 50% of the issued and outstanding shares of common stock of Unimin. In addition to the foregoing, this Agreement may be terminated at any time by written consent of the Parties.

Section 3.2 Effect of Termination

In the event of termination of this Agreement pursuant to Section 3.1, this Agreement shall become void and of no effect with no liability on the part of any Party; provided, however, no such termination shall relieve any Party from any liability for any breach of this Agreement occurring prior to such termination and the provisions of this Article III, shall survive any such termination. Notwithstanding the foregoing, termination of this Agreement shall not prevent any Party from seeking any remedies (at law or in equity) against the other Party for that Party’s breach of any of the terms of this Agreement prior to the date of termination.

Section 3.3 Entire Agreement; Assignment.

This Agreement (together with the Merger Agreement, the Distribution Agreement and the Agency Agreement, to the extent referred to in this Agreement) and any documents delivered by the Parties in connection herewith constitute the entire agreement among the Parties with respect to the subject matter hereof and supersedes all other prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. Nothing in this Agreement, express or implied, is intended to or shall confer upon any person other than the

Parties any rights or remedies hereunder. Neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of law or otherwise, by any Party without the prior written consent of the other Party, and any such assignment without such prior written consent shall be null and void. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of, and be enforceable by, the Parties and their respective permitted successors and assigns.

Section 3.4 Amendments and Waivers

This Agreement may only be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an amendment, by each Party, or in the case of a waiver, by the Party against whom the waiver is to be effective. No failure or delay by Sibelco or Unimin in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder.

The Board of Directors may decrease the number of shares of Preferred Stock designated as any existing series to a number not less than the number of shares of such series then outstanding by a resolution decreasing the number of shares of Preferred Stock designated as such existing series, and the number of shares no longer designated as such series shall become authorized, unissued, and undesignated shares of Preferred Stock.

2. Provisions Relating to Common Stock.

a. Subject to the terms of the Stockholders Agreement dated [•], 201[•] among the Corporation, SCR-Sibelco NV (Sierra) and the Stockholders named therein (the Stockholders Agreement), the following provisions shall apply with respect to Common Stock:

i. Each share of Common Stock shall have identical rights and privileges in every respect. Common Stock shall be subject to the express terms of Preferred Stock and any series thereof. Except as may otherwise be provided in this A&R Certificate, in a Preferred Stock Designation or by applicable law, the holders of shares of Common Stock shall be entitled to one vote for each such share upon all questions presented to the Stockholders, the holders of shares of Common Stock shall have the exclusive right to vote for the election of members of the Board of Directors (each such member, a Director) and for all other purposes, and the holders of Preferred Stock shall not be entitled to vote at or receive notice of any meeting of Stockholders. Each holder of Common Stock shall be entitled to notice of any Stockholders’ meeting in accordance with the Bylaws of the Corporation (the Bylaws, as in effect at the time in question) and applicable law on all matters put to a vote of the Stockholders.

ii. Notwithstanding the foregoing, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this A&R Certificate (including any Preferred Stock Designation) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this A&R Certificate (including any Preferred Stock Designation) or pursuant to the DGCL (or any successor provision thereto).

iii. Subject to the prior rights and preferences, if any, applicable to shares of Preferred Stock or any series thereof, the holders of shares of Common Stock shall be entitled to receive ratably in proportion to the number of shares of Common Stock held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared thereon by the Board of Directors at any time and from time to time out of any funds of the Corporation legally available therefor.

iv. Except as otherwise provided in a Preferred Stock Designation, in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation, after distribution in full of the preferential amounts, if any, to be distributed to the holders of shares of Preferred Stock or any class or series thereof, the holders of shares of Common Stock shall be entitled to receive all of the remaining assets of the Corporation available for distribution to the Stockholders, ratably in proportion to the number of shares of Common Stock held by them. Except as otherwise provided in a Preferred Stock Designation, a liquidation, dissolution or winding-up of the Corporation, as such terms are used in this Paragraph (d), shall not be deemed to be occasioned by or to include any consolidation or merger of the Corporation with or into any other corporation or corporations or other entity or a sale, lease, exchange or conveyance of all or a part of the assets of the Corporation.

v. Except as otherwise provided in a Preferred Stock Designation, the number of authorized shares of Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the

holders of a majority in voting power of Common Stock or Preferred Stock entitled to vote thereon irrespective of the provisions of Section 242(b)(2) of the DGCL (or any successor provision thereto), and no vote of the holders of either Common Stock or Preferred Stock voting separately as a class shall be required therefor.

3. General.

a. Subject to the foregoing provisions of this A&R Certificate, any then-existing Preferred Stock Designation and the Stockholders Agreement, the Corporation may issue shares of Preferred Stock and Common Stock from time to time for such consideration (not less than the par value thereof) as may be fixed by the Board of Directors, which is expressly authorized to fix the same in its sole and absolute discretion subject to the foregoing conditions. Shares so issued for which the consideration shall have been paid or delivered to the Corporation shall be deemed fully paid stock and shall not be liable to any further call or assessment thereon, and the holders of such shares shall not be liable for any further payments in respect of such shares.

b. Subject to the Stockholders Agreement, the Corporation shall have authority to create and issue rights and options entitling their holders to purchase shares of the Corporation’s capital stock of any class or series or other securities of the Corporation, and such rights and options shall be evidenced by instrument(s) approved by the Board of Directors. The Board of Directors shall be empowered to set the exercise price, duration, times for exercise, and other terms of such options or rights; provided, however, that the consideration to be received for any shares of capital stock subject thereto shall not be less than the par value thereof.

c. The Corporation shall be entitled to treat the person in whose name any share of its stock is registered as the owner thereof for all purposes and shall not be bound to recognize any equitable or other claim to, or interest in, such share on the part of any other person, whether or not the Corporation shall have notice thereof, except as expressly provided by applicable law.

FIFTH. Subject to the Stockholders Agreement, the total number of Directors shall be determined from time to time by resolution of the Board of Directors. Each Director shall serve for a term of one year or until his or her earlier death, resignation or removal.

SIXTH. Prior to the earlier of (i) the close of business on the tenth business day following the date on which Sierra and its affiliates (as such term is used in the Stockholders Agreement) no longer beneficially own more than 50% of the outstanding shares of Common Stock and (ii) the close of business on the business day following public announcement by Sierra that Sierra has made an election that the “Trigger Date” has occurred (the earlier of (i) and (ii), the Trigger Date), any action required or permitted to be taken at any annual meeting or special meeting of

the Stockholders may be taken without a meeting, without prior notice and without a vote of Stockholders, if a consent or consents in writing, setting forth the action so taken, is or are signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted. On and after the Trigger Date, subject to the rights of holders of any series of Preferred Stock, any action required or permitted to be taken by the Stockholders must be taken at a duly held annual or special meeting of Stockholders and may not be taken by any consent in writing of such Stockholders.

SEVENTH. Special meetings of Stockholders may be called only by the Board of Directors pursuant to a resolution adopted by a majority of the total number of Directors which the Corporation would have if there were no vacancies; provided, however, that prior to the Trigger Date, special meetings of the Stockholders may also be called by the Secretary of the Corporation at the request of the holders of record of a majority of the outstanding shares of Common Stock. From and after the Trigger Date, and subject to the rights of holders of any series of Preferred Stock, the Stockholders do not have the power to call a special meeting of Stockholders.

EIGHTH. In furtherance of, and not in limitation of, the powers conferred by the DGCL, subject to the Stockholders Agreement, the Board of Directors is expressly authorized to adopt, amend or repeal the Bylaws. The Bylaws shall not be adopted, altered, amended or repealed by the Stockholders (i) prior to the Trigger Date, except by the affirmative vote of holders of not less than a majority in voting power of the then-outstanding shares of Common Stock entitled to vote generally in the election of Directors (considered for this purpose as one class) or (ii) after the Trigger Date, except by the affirmative vote of holders of not less than 66 2/3% in voting power of the then-outstanding shares of Common Stock entitled to vote generally in the election of Directors (considered for this purpose as one class).

NINTH. Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and the Stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof or on the application of any receiver or receivers appointed for the Corporation under the provisions of Section 291 of the DGCL or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under the provisions of Section 279 of the DGCL order a meeting of the creditors or class of creditors, and/or of the Stockholders or class of Stockholders, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the Stockholders or class of Stockholders, as the case may be, agree to any compromise or arrangement and to any reorganization of the Corporation as a consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the Stockholders or class of Stockholders, as the case may be, and also on the Corporation.

TENTH. No Director shall be liable to the Corporation or the Stockholders for monetary damages for breach of fiduciary duty as a Director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as it now exists. In addition to the circumstances in which a Director is not personally liable as set forth in the preceding sentence, a Director shall not be liable to the fullest extent permitted by any amendment to the DGCL hereafter enacted that further limits the liability of a Director.

The Corporation shall indemnify and advance expenses to each Director or Officer to the fullest extent permitted by the DGCL.

Any amendment, repeal or modification of this Article Tenth shall be prospective only and shall not affect any limitation on liability of a Director for acts or omissions occurring prior to the date of such amendment, repeal or modification.

ELEVENTH. To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its subsidiaries, renounces any interest or expectancy of the Corporation and its subsidiaries in, or in being offered an opportunity to participate in, the business opportunities that are from time to time presented to Sierra or any of its officers, directors, agents, members, affiliates and subsidiaries (other than the Corporation and its subsidiaries) (each, a Specified Party), or are business opportunities in which a Specified Party participates or desires to participate, even if the opportunity is one that the Corporation or its subsidiaries might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each such Specified Party shall have no duty to communicate or offer such business opportunity to the Corporation and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation or any of its subsidiaries or any stockholder, for breach of any fiduciary or other duty, as a director or officer or controlling stockholder or otherwise, by reason of the fact that such Specified Party pursues or acquires such business opportunity, directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or its subsidiaries. Notwithstanding the foregoing, a Specified Party who is a Director and who is offered any business opportunity in his or her capacity as a Director or Officer (a Directed Opportunity) shall be obligated to communicate such Directed Opportunity to the Corporation; provided, however, that all of the protections of this Article Eleventh shall otherwise apply to the Specified Parties with respect to such Directed Opportunity, including, without limitation, the ability of the Specified Parties to pursue or acquire such Directed Opportunity or to direct such Directed Opportunity to another person.

Neither the amendment nor repeal of this Article Eleventh, nor the adoption of any provision of this A&R Certificate or the Bylaws, nor, to the fullest extent permitted by applicable law, any modification of law, shall eliminate, reduce or otherwise adversely affect any right or protection of any person granted pursuant hereto existing at, or arising out of or related to any event, act or omission that occurred prior to, the time of such amendment, repeal, adoption or modification (regardless of when any proceeding (or part thereof) relating to such event, act or omission arises or is first threatened, commenced or completed).

If any provision or provisions of this Article Eleventh shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (a) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article Eleventh (including, without limitation, each portion of any paragraph of this Article Eleventh containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and (b) to the fullest extent possible, the provisions of this Article Eleventh (including, without limitation, each such portion of any paragraph of this Article Eleventh containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect the Directors, Officers, its employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.

This Article Eleventh shall not limit any protections or defenses available to, or indemnification or advancement rights of, any Director or Officer under this A&R Certificate, the Bylaws or applicable law. Any person or entity purchasing or otherwise acquiring any interest in any securities of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article Eleventh.

TWELFTH. The Corporation elects not to be governed by, and shall not be subject to the provisions of, Section 203 of the DGCL, as now in effect or hereafter amended, or any successor statute thereto, as permitted under and pursuant to subsection (b)(3) thereof.

THIRTEENTH. The Corporation shall have the right, subject to any express provisions or restrictions contained in this A&R Certificate, the Bylaws or the Stockholders Agreement, from time to time, to amend this A&R Certificate or any provision hereof in any manner now or hereafter provided by law, and all rights and powers of any kind conferred upon a Director or Stockholder by this A&R Certificate or any amendment hereof are subject to such right of the Corporation.

FOURTEENTH. Notwithstanding any other provision of this A&R Certificate or the Bylaws (and in addition to any other vote that may be required by law, this A&R Certificate, the Bylaws or the Stockholders Agreement), following the Trigger Date, the affirmative vote of the holders of at least 75% in voting power of the outstanding shares of Common Stock entitled to vote generally in the election of Directors (voting together as one class) shall be required to amend, alter or repeal ARTICLES FIFTH, SIXTH, SEVENTH, EIGHTH, ELEVENTH and FOURTEENTH of this A&R Certificate or to adopt any provision inconsistent therewith.

FIFTEENTH. Unless the Corporation consents in writing to the selection of an alternative forum, to the fullest extent permitted by law, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any Director, Officer, employee or agent of the Corporation to the Corporation or the Stockholders, (iii) any action asserting a claim against the Corporation arising pursuant to any provision of the DGCL, this A&R Certificate or the Bylaws, or (iv) any action asserting a claim against the Corporation governed by the internal affairs doctrine, in each such case subject to said Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article Fifteenth.

ARTICLE 2

STOCKHOLDERS

2.1 Annual Meeting. The annual meeting of the stockholders of the Corporation shall be held on such date and at such place, if any, either within or without the State of Delaware, and time as may be fixed by resolution of the Board, unless, subject to the Corporation’s Amended and Restated Certificate of Incorporation as it may be further amended and restated from time to time (the Certificate of Incorporation), the stockholders have acted by written consent as permitted by the Delaware General Corporation Law, or any successor provisions thereto (DGCL). Any proper business may be transacted at the annual meeting. The Board may postpone, reschedule or cancel any annual meeting of stockholders previously scheduled by the Board.

2.2 Special Meeting. Special meetings of stockholders may be called in the manner provided in the Certificate of Incorporation. The Board may postpone, reschedule or cancel any special meeting of the stockholders previously scheduled by the Board.

2.3 Record Date.

(a) In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than sixty (60) nor less than ten (10) days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting, and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

(b) In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect of any change, conversion or exchange of stock or for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall not be more than sixty (60) days prior to such action. If no such record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

(c) Unless otherwise restricted by the Certificate of Incorporation, in order that the Corporation may determine the stockholders entitled to express consent to corporate action in writing without a meeting, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board. If no record date for determining stockholders entitled to express consent to corporate action in writing without a meeting is fixed by the Board, (i) when no prior action of the Board is required by law, the record date for such purpose shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation in accordance with applicable law, and (ii) if prior action by the Board is required by law, the record date for such purpose shall be at the close of business on the day on which the Board adopts the resolution taking such prior action.

2.4 Stock List. A complete list of stockholders entitled to vote at any meeting of stockholders (provided, however, if the record date for determining the stockholders entitled to vote is less than ten (10) days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date), arranged in alphabetical order for each class of stock and showing the address of each such stockholder and the number of shares registered in the name of such stockholder, shall be open to the examination of any stockholder, for any purpose germane to the meeting, for a period of at least ten (10) days prior to the meeting, either on a reasonably accessible electronic network, provided that the information required to gain access to the list is provided with the notice of the meeting, or during ordinary business hours, at the principal place of business of the Corporation. The stock list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. The stock ledger of the Corporation shall be the only evidence as to who are the stockholders entitled by this section to examine the list required by this section or to vote in person or by proxy at any meeting of the stockholders.

2.5 Place of Meeting. The Board shall designate the place of meeting for any annual meeting or for any special meeting of the stockholders. If no designation is so made, the place of meeting shall be the principal executive offices of the Corporation. The Board, acting in its sole discretion, may establish guidelines and procedures in accordance with applicable provisions of the DGCL and any other applicable law for the participation by stockholders and proxyholders in a meeting of stockholders by means of remote communications, and may determine that any meeting of stockholders will not be held at any place but will be held solely by means of remote communication. Stockholders and proxyholders complying with such procedures and guidelines and otherwise entitled to vote at a meeting of stockholders shall be deemed present in person and entitled to vote at a meeting of stockholders, whether such meeting is to be held at a designated place or solely by means of remote communication.

2.6 Notice of Meeting. Whenever stockholders are required or permitted to take any action at a meeting, notice of the meeting, stating the place, day and hour of the meeting, the means of remote communications, if any, by which stockholders and proxyholders may be deemed present in person and vote at such meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given. Unless otherwise provided by law, the Certificate of Incorporation or these Bylaws, the notice shall be given not less than ten (10) days nor more than 60 days before the date of the meeting, in a manner pursuant to Section 7.7 hereof, to each stockholder of record entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting. If mailed, such notice shall be deemed to be delivered when deposited in the United States mail with postage thereon prepaid, addressed to the stockholder at his address as it appears on books of the Corporation. The Corporation may provide stockholders with notice of a meeting by electronic transmission in accordance with applicable law.

2.7 Quorum and Adjournment of Meetings. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, the holders of a majority in voting power of the outstanding shares of the Corporation entitled to vote at the meeting (the Voting Stock), represented in person or by proxy, shall constitute a quorum at a meeting of stockholders. Where a separate vote by a class or series (or classes or series) of stock is required, the holders of a majority of the outstanding shares of such class or series (or classes or series), represented in person or by proxy, shall constitute a quorum of such class or series with respect to the vote on that matter. Shares of its own stock belonging to the Corporation or to another corporation, if a majority of the voting power of the shares entitled to vote in the election of directors of such other corporation are held, directly or indirectly, by the Corporation, shall neither be entitled to vote nor be counted by quorum purposes; provided, however, that the foregoing shall not limit the right of the Corporation or any subsidiary of the Corporation to vote stock, including but not limited to its own stock, held by it in fiduciary capacity. The chairman of the meeting or the holders of a majority in voting power of the shares so represented at a meeting may adjourn the meeting from time to time, whether or not there is such a quorum. When a meeting is adjourned to another time or place, unless these Bylaws otherwise require, notice need not be given of the adjourned meeting if the time and place, if any, thereof are announced at the meeting at which the adjournment is taken. If the adjournment is for more than thirty (30) days, a notice shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix as the record date for determining stockholders entitled to receive notice of the adjourned meeting the same or an earlier date as that fixed for determination of stockholders of record entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date so fixed for notice of such adjourned meeting. At the adjournment meeting, the Corporation may transact any business which might have been transacted at the original meeting. The stockholders present at a duly called meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

2.8 Proxies. At all meetings of stockholders, each stockholder entitled to vote at a meeting may authorize another person to act for such stockholder by proxy given in any manner permitted by law. Any copy, facsimile transmission or other reliable reproduction of the writing or transmission created pursuant to this section may be substituted or used in lieu of the original writing or transmission for any and all purposes for which the original writing or transmission could be used, provided that such copy, facsimile transmission or other reproduction shall be a complete reproduction of the entire original writing or transmission. No proxy may be voted or acted upon after the expiration of three (3) years from the date of such proxy, unless such proxy provides for a longer period. Every proxy is revocable at the pleasure of the stockholder executing it unless the proxy states that it is irrevocable and applicable law makes it irrevocable. A stockholder may revoke any proxy that is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing another duly executed proxy bearing a later date with the Secretary.

2.9 Notice of Stockholder Business and Nominations.

(a) Annual Meetings of Stockholders.

(i) Nominations of persons for election to the Board and the proposal of other business to be considered by the stockholders may be made at an annual meeting of stockholders only (A) pursuant to the Corporation’s notice of meeting (or any supplement thereto), (B) by or at the direction of the Board (or any committee thereof) or (C) by any stockholder of the Corporation who (1) was a stockholder of record at the time of giving of notice provided for in these Bylaws and at the time of the annual meeting, (2) is entitled to vote at the meeting and (3) subject to Section 2.9(c)(v), complies with the notice procedures set forth in these Bylaws as to such business or nomination. Clause (i)(C) of this Section 2.9(a)(i) shall be the exclusive means for a stockholder to make nominations or submit other business (other than matters properly brought under Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the Exchange Act), and included in the Corporation’s notice of meeting) before an annual meeting of the stockholders.

(ii) Without qualification, for any nominations or any other business to be properly brought before an annual meeting by a stockholder pursuant to Section 2.9(a)(i)(C) of these Bylaws, the stockholder must have given timely notice thereof in writing to the Secretary and such other business must otherwise be a proper matter for stockholder action under the DGCL. To be timely, a stockholder’s notice shall be delivered to the Secretary at the principal executive offices of the Corporation not earlier than the close of business on the 120th day and not later than the close of business on the 90th day prior to the first anniversary of the preceding year’s annual meeting (which date shall, for purposes of the Corporation’s first annual meeting of stockholders after its shares of Common Stock are first publicly traded, be deemed to have occurred on [•]); provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to the date of such annual meeting and not later than the close of business

on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made by the Corporation. In no event shall any adjournment or postponement of an annual meeting or the announcement thereof commence a new time period (or extend any time period) for the giving of a stockholder’s notice as described above. To be in proper form, a stockholder’s notice (whether given pursuant to this Section 2.9(a)(ii) or Section 2.9(a)(iii)) to the Secretary must:

(A) set forth, as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (1) the name and address of such stockholder, as they appear on the Corporation’s books, and of such beneficial owner, if any, (2) (a) the class or series and number of shares of the Corporation which are, directly or indirectly, owned beneficially and of record by such stockholder and such beneficial owner, (b) any option, warrant, convertible security, stock appreciation right, or similar right with an exercise or conversion privilege or a settlement payment or mechanism at a price related to any class or series of shares of the Corporation or with a value derived in whole or in part from the value of any class or series of shares of the Corporation, whether or not such instrument or right shall be subject to settlement in the underlying class or series of capital stock of the Corporation or otherwise (a Derivative Instrument) directly or indirectly owned beneficially by such stockholder and such beneficial owner, if any, and any other direct or indirect opportunity to profit or share in any profit derived from any increase or decrease in the value of shares of the Corporation directly or indirectly owned by such stockholder and such beneficial owner, if any, (c) a description of any proxy, contract, arrangement, understanding, or relationship pursuant to which such stockholder and such beneficial owner, if any, has a right to vote any shares of any security of the Company, (d) any short interest in any security of the Company (for purposes of these Bylaws a person shall be deemed to have a short interest in a security if such person directly or indirectly, through any contract, arrangement, understanding, relationship or otherwise, has the opportunity to profit or share in any profit derived from any decrease in the value of the subject security) directly or indirectly owned by such stockholder and such beneficial owner, if any, (e) any rights to dividends on the shares of the Corporation owned beneficially by such stockholder and such beneficial owner, if any, that are separated or separable from the underlying shares of the Corporation, (f) any proportionate interest in shares of the Corporation or Derivative Instruments held, directly or indirectly, by a general or limited partnership in which such stockholder and such beneficial owner, if any, is a general partner or, directly or indirectly, beneficially owns an interest in a general partner and (g) any performance-related fees (other than an asset-based fee) that such stockholder and such beneficial owner, if any, is entitled to based on any increase or decrease in the value of shares of the Corporation or Derivative Instruments, if any, as of the date of such notice, including

Any director or any officer, whether elected or appointed, may resign at any time by giving written notice, including by electronic transmission, of such resignation to the Chairman of the Board, the Chief Executive Officer, the President or the Secretary, and such resignation shall be deemed to be effective as of the close of business on the date said notice is received by the Chairman of the Board, the Chief Executive Officer, the President or the Secretary, or at such later time as is specified therein. No formal action shall be required of the Board or the stockholders to make any such resignation effective.

7.6 Indemnification.

(a) Scope

(i) Each person who was or is a party, is threatened to be made a party to or is involved in any Proceeding (other than a Proceeding by or in the right of the Corporation), by reason of the fact that he or she or a person of whom he or she is the legal representative is or was, or has agreed to become, a director or officer of a Subject Enterprise or by reason of any act or omission by such person in such capacity, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all Expenses and liabilities which were suffered or reasonably incurred by such person in connection therewith, so long as such person acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Corporation and, in the case of a criminal proceeding, had no reasonable cause to believe that such person’s conduct was unlawful. Such indemnification shall inure to the benefit of such person’s heirs, executors and administrators.

(ii) Each person who was or is a party or is threatened to be made a party to or is involved in any Proceeding brought by or in the right of the Corporation to procure a judgment in its favor by reason of the fact that he or she or a person of whom he or she is the legal representative is or was, or has agreed to become, a director, officer, employee, agent or fiduciary of a Subject Enterprise, or by reason of any act or omission by such person in such capacity, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all Expenses suffered or incurred by such person in connection therewith, so long as such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Corporation. Such indemnification shall inure to the benefit of such person’s heirs, executors and administrators.

(iii) Notwithstanding Section 7.6(a)(ii), no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been finally adjudged to be liable to the Corporation in a final adjudication by a court of competent jurisdiction, unless and to the extent that the Court of Chancery of the State of Delaware, or the court in which such Proceeding shall have been brought or is pending, shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnification.

(iv) Notwithstanding Section 7.6(a)(i) and Section 7.6(a)(ii), except as provided in Section 7.6(c) or the last sentence of Section 7.6(d), the Corporation shall indemnify any such person seeking indemnification in connection with a Proceeding (or part thereof) initiated by such person, including any Proceeding (or part thereof) initiated by such person against the Corporation or its directors, officers, employees or other indemnitees only if (i) such Proceeding (or part thereof) was authorized by the Board prior to its initiation or (ii) the Corporation, by action of its Board, provides the indemnification, in its sole discretion, pursuant to the powers vested in the Corporation under applicable law.

(v) The Corporation shall, to the fullest extent not prohibited by law, advance all Expenses incurred by a present or former director or officer in defending any Proceeding prior to the final disposition of such Proceeding upon written request of such person and delivery of an undertaking by such person to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the Corporation. Such advances shall be paid by the Corporation within thirty (30) days after the receipt by the Corporation of a statement or statements from the claimant requesting such advance or advances from time to time.

(b) The Corporation may, by action of its Board, provide indemnification and advancement of expenses to employees and agents of the Corporation, individually or as a group, within the same scope and effect as the indemnification of its directors and officers.

(c) To obtain indemnification or advancement of Expenses under these Bylaws, a claimant shall submit to the Corporation a written request, including documentation and information which is reasonably available to the claimant and is reasonably necessary to determine whether and to what extent the claimant is entitled to indemnification following the final disposition of such action, suit or proceeding. Upon written request by a claimant who is a current director and officer of the Corporation for indemnification pursuant to the first sentence of this paragraph (c), a determination by the Corporation, if required by applicable law, with respect to the claimant’s entitlement thereto shall be made as follows: (i) by a majority vote of the Disinterested Directors (as hereinafter defined), even though less than a quorum of the Board, (ii) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum, (iii) if there are no such Disinterested Directors, or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion, or (iv) if so directed by the Board, by the stockholders of the Corporation. The Independent Counsel shall be selected by the Corporation; provided, however, that the claimant may, within ten (10) days after written notice of selection shall be given, deliver to the Corporation written objection to such selection, which may only be asserted on the grounds that the Independent Counsel does not meet the definition of Independent Counsel as defined by these Bylaws. Such determination of entitlement to indemnification shall be made not later than ninety (90) days after receipt by the Corporation of a written request for indemnification. If it is so determined that the claimant is entitled to indemnification, payment to the claimant shall be made within ten (10) days after such determination. In any proceeding brought to enforce the right of a person to receive indemnification to which such person is entitled under this Section 7.6, the person, persons or entity making such determination shall, to the fullest extent not prohibited by the DGCL or other applicable law and these Bylaws presume that such person is entitled to indemnification and the Corporation shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that presumption. A prior determination by the Corporation (including the Board or any committee thereof, its independent legal counsel, or its stockholders) that the claimant has not met such applicable standard of conduct does not itself constitute evidence that the claimant has not met the applicable standard of conduct. In any proceeding brought to enforce a claim for advances to which a person is entitled under Section 7.6(a)(v), the person seeking an advance need only show that he or she has satisfied the requirements expressly set forth in Section 7.6(a)(v).

(d) If the Board or the Independent Counsel, as applicable, shall have failed to make a determination as to entitlement to indemnification within ninety (90) days after receipt by the Corporation of such request, such claimant shall be entitled to an adjudication by a court of such claimant’s option to such entitlement. Alternatively, such claimant, at his option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the

American Arbitration Association. The termination of any Proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself: (i) create a presumption that the claimant did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal Proceeding, that the claimant had reasonable cause to believe that the claimant’s conduct was unlawful; or (ii) otherwise adversely affect the rights of the claimant to indemnification, except as may be provided herein. All Expenses incurred by such person in connection with successfully establishing such person’s right to indemnification or advancement of expenses under this Section 7.6, in whole or in part, shall also be indemnified by the Corporation to the fullest extent permitted by law.

(e) If a determination shall have been made pursuant to Section 7.6(c) of these Bylaws that the claimant is entitled to indemnification, the Corporation shall be bound by such determination and shall be precluded from asserting that such determination has not been made in any judicial Proceeding commenced pursuant to Section 7.6(d) of these Bylaws.

(f) The Corporation shall be precluded from asserting in any judicial Proceeding commenced pursuant to Section 7.6(d) of these Bylaws that the procedures and presumptions of these Bylaws are not valid, binding and enforceable and shall stipulate in such Proceeding that the Corporation is bound by all the provisions of these Bylaws.

(g) The right to indemnification and the payment of Expenses incurred in defending a Proceeding in advance of its final disposition conferred in these Bylaws shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, Bylaws, agreement, vote of stockholders or Disinterested Directors or otherwise. No repeal or modification of these Bylaws shall in any way diminish or adversely affect the rights of any director, officer, employee or agent of the Corporation hereunder in respect of any occurrence or matter arising prior to any such repeal or modification.

(h) If any provision or provisions of this Section 7.6 shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Section 7.6 (including, without limitation, each portion of any paragraph of this Section 7.6 containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (ii) to the fullest extent possible, the provisions of this Section 7.6 (including, without limitation, each such portion of any paragraph of this Section 7.6 containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable. If this Section 7.6 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless (A) indemnify each director and officer of the Corporation as to Expenses and liabilities paid in settlement with respect to any Proceeding, including an action by or in the right of the Corporation,

and (B) advance Expenses to each director or officer of the Corporation entitled to advancement of expenses under Section 7.6(a)(v) in accordance therewith, in each case, to the fullest extent permitted by any applicable portion of this Section 7.6 that shall not have been invalidated and to the fullest extent permitted by applicable law.

Expenses also shall include, without limitation, (1) expenses incurred in connection with any appeal resulting from, incurred by the claimant in connection with, arising out of, or in respect of or relating to any cost bond, supersedeas bond, or other appeal bond or its equivalent, (2) expenses incurred by the claimant in connection with interpretation, enforcement or defense of such claimant’s rights, by litigation or otherwise, (3) any federal, state, local or foreign taxes imposed on the claimant as a result of the actual or deemed receipt of any payments under these Bylaws, and (4) any interest, assessments or other changes in respect of the foregoing.

The Corporation hereby acknowledges and agrees that (i) the Corporation shall be the indemnitor of first resort with respect to any Proceeding, Expense, liability or matter that is the subject of this Section 7.6, (ii) the Corporation shall be primarily liable for all such obligations and any indemnification afforded to an Indemnitee in respect of any Proceeding, Expense, liability or matter that is the subject of this Section 7.6, whether created by law, organizational or constituent documents, contract or otherwise, (iii) any obligation of any other Persons with whom or which an Indemnitee may be associated (including Sierra) to indemnify such Indemnitee and/or advance Expenses or liabilities to such Indemnitee in respect of any Proceeding shall be secondary to the obligations of the Corporation hereunder, (iv) the Corporation shall be required to indemnify each Indemnitee and advance Expenses to each Indemnitee hereunder to the fullest extent provided herein without regard to any rights such Indemnitee may have against any other Person with whom or which such Indemnitee may be associated (including Sierra) or insurer of any such Person, and (v) the Corporation irrevocably waives, relinquishes and releases to the fullest extent permitted by law any other Person with whom or which an Indemnitee may be associated (including Sierra) from any claim of contribution, subrogation or any other recovery of any kind in respect of amounts paid by the Corporation hereunder.

Without limiting the manner by which notice otherwise may be given effectively, notice to any stockholder shall be deemed given: (i) if by facsimile, when directed to a number at which the stockholder has consented to receive notice; (ii) if by electronic mail, when
