Section 2.2 Company Business Plan.

(a) Pursuant to the Subscription Agreement, Holdco Inc. and Buyer prepared and agreed to a business plan with respect to the Company covering the Company and its Subsidiaries for the period from January 1, 2015 through December 31, 2019, which business plan includes estimated Annual Consolidated Fixed Operating Expense Budgets and estimated Annual Consolidated Maintenance Capex Budgets for each fiscal year in such period (as such business plan may be amended from time to time in accordance with this Agreement, the “Company Business Plan”). The Company Business Plan in effect as of the date hereof (the “Initial Company Business Plan”) is attached as Exhibit D hereto, and the 2015 Annual Consolidated Fixed Operating Expense Budget and the 2015 Annual Consolidated Maintenance Capex Budget are attached as Exhibits E and F hereto, respectively.

(b) From time to time, management may recommend for Board approval amendments to the Company Business Plan. Management shall also annually recommend for Board approval a final Annual Consolidated Fixed Operating Expense Budget and a final Annual Consolidated Maintenance Capex Budget for the following fiscal year and an extension to the Company Business Plan to roll the plan forward for an additional fiscal year. The Board may adopt any amendments to the Company Business Plan and approve the final Annual Consolidated Fixed Operating Expense Budget, the final Annual Consolidated Maintenance Capex Budget and the rolling forward of the Company Business Plan by the affirmative vote of a majority of the Directors present at a duly convened meeting of the Board at which a quorum is present in accordance with Section 2.8 (provided, for the avoidance of doubt, that the adoption of elements of the Company Business Plan, the Annual Consolidated Fixed Operating Expense Budget and the Annual Consolidated Maintenance Capex Budget shall constitute a “Major Decision” if such elements of the Company Business Plan or budgets, if adopted separately by the Board, would constitute “Major Decisions” and, provided further, that, an item shall constitute a “Major Decision” only in the first instance in which it is voted on by the Board, unless later amended in ways that would meet the criteria of a Major Decision). In addition, with respect to expenses added to roll forward the business plan to a new year, then to the extent the Annual Consolidated Fixed Operating Expense Budget or Annual Consolidated Maintenance Capex Budget for the new year (each, a “Roll-Forward Budget”) is greater than a 10% increase from those items in the prior year, the addition of these new year expenses shall constitute a “Major Decision.”

(c) In the event Board approval is not obtained prior to the beginning of the fiscal year of the Company to which such budget corresponds, then the Company and its Subsidiaries shall continue to operate under the prior year’s Annual Consolidated Fixed Operating Expense Budget or Annual Consolidated Maintenance Capex Budget, as applicable, and as adjusted for inflation, until such time as the requisite Board approval is obtained.

Officers.

The President and his or her direct reports shall be responsible for the day-to-day management of the Company. Management shall have the authority to take all actions on behalf of the Company not otherwise reserved to the Board or the Shareholders pursuant to this Agreement or the IBCL.

Affiliate Transactions.

Any Affiliate Transaction shall be negotiated on an arms’ length basis, and shall involve economic terms no less favorable to the Company and its Subsidiaries than those that could be obtained from a Third Party on an arms’ length basis. The Parties acknowledge that, as of the date hereof, certain Affiliates of the Company provide various services to the Company and its Subsidiaries, including tax, accounting, human resources, legal, financial, information technology, regulatory, environmental, safety, construction and engineering services, and that all such services shall continue in the ordinary course of business following the date hereof.

Section 2.3 Put Right.

(a) For so long as the Pro Rata Percentage of an Investor Shareholder is equal to or greater than five percent (5%), if (i) an Adverse Recovery Event occurs, (ii) a Major Decision is approved by the Board but at least one Investor Nominee of such Investor

Shareholder votes against such Major Decision, or (iii) such Investor Shareholder or any of its Affiliates exercise a put right with respect to any other equity interest in the Companies Beneficially Owned by such Investor Shareholder or its Affiliates, then, in each case, such Investor Shareholder shall be a “Put Right Shareholder” and the occurrence of such Adverse Recovery Event, the approval of such Major Decision or the exercise of such put right shall constitute a “Put Triggering Event”.

(b) If a Put Triggering Event occurs, a Put Right Shareholder may, within thirty (30) days of such Put Triggering Event, provide written notice to Holdco Inc. that a Put Triggering Event has occurred, including a description of such Put Triggering Event (a “Put Triggering Event Notice”).

(c) At any time between forty-five (45) and sixty (60) days after delivery of a Put Triggering Event Notice, each Put Right Shareholder shall have the right, but not the obligation, to deliver a written notice to Holdco Inc. and the Company (a “Put Exercise Notice”) of the Put Right Shareholder’s decision to require Holdco Inc. (or, at Holdco Inc.’s election, its Affiliate or a Third Party) to purchase all of the Shares then held by such Put Right Shareholder and its Affiliates (in each case, the “Put Shares”), in accordance with and subject to the conditions and limitations set forth in this Section 2.15(c) (such purchase and sale of the Put Shares, the “Put Sale”). A Put Exercise Notice shall be effective only if the Put Triggering Event is continuing as of the date of such Put Exercise Notice (the “Put Exercise Date”), in which case Holdco Inc. (or, at Holdco Inc.’s election, its Affiliate or a Third Party) will be required to purchase the Put Shares in the Put Sale, in accordance with and subject to the conditions and limitations set forth in this Section 2.15.

(d) Subject to Section 2.15(h), a Put Exercise Notice shall obligate Holdco Inc. (or, at Holdco Inc.’s election, its Affiliate or a Third Party) to purchase, and each Put Right Shareholder who has delivered a Put Exercise Notice to sell, the Put Shares for a purchase price equal to the fair market value of the Put Shares as of immediately prior to the Put Triggering Event, without taking into account the Put Triggering Event and assuming closing of the Put Sale seventy-five (75) days after the Put Exercise Date (as may be adjusted in accordance with Section 2.15(d)(iv), the “Put Price”), that is determined as between Holdco Inc., on the one hand, and, on the other hand, each Put Right Shareholder separately from and independent of any other Put Right Shareholder, in each case in accordance with the procedures below:

(i) Within twenty-five (25) days following the Put Exercise Date, the Company shall appoint a Valuation Arbiter, subject to Holdco Inc.’s and the Put Right Shareholder’s prior written consent (not to be unreasonably withheld), to assist in determining the Put Price, the costs and expenses of which shall be borne by the Company, except as provided in Section 2.15(g). Holdco Inc. and the Put Right Shareholder shall, within thirty (30) days of the Put Exercise Date, separately submit to the Valuation Arbiter, on a confidential basis and on the basis of assumptions agreed between Holdco Inc. and the Put Right Shareholder that are consistent with the provisions of this Section 2.15, the price which each of Holdco Inc. and such Put Right Shareholder believes should constitute the Put Price.

(ii) If the lower of the two prices submitted by Holdco Inc. and the Put Right Shareholder to the Valuation Arbiter is no more than ten percent (10%) lower than the greater price, then the Put Price shall be the average of the two prices. The Valuation Arbiter shall provide written notice of whether the Put Price can be immediately determined in accordance with this Section 2.15(d)(ii) to the Company, Holdco Inc. and the Put Right Shareholder as promptly as reasonably practicable following its receipt of Holdco Inc.’s and the Put Right Shareholder’s proposed price. If the Put Price can be so determined, such notice shall also set forth the price proposed by each of Holdco Inc. and the Put Right Shareholder and the final Put Price as determined in accordance with this Section 2.15(d)(ii).

(iii) If the lower value is more than ten percent (10%) lower than the greater value, then the Valuation Arbiter shall undertake an independent determination of the fair market value of the Put Shares as of immediately prior to the Put Triggering Event, without taking into account the Put Triggering Event, as adjusted to account for any subsequent dividends or capital contributions. In determining the fair market value, the Valuation Arbiter shall take into account all relevant facts, circumstances and assumptions, including (a) the existence of (i) a willing buyer and (ii) a willing seller, neither of which is under compulsion to consummate the sale and each of whom is dealing on an arms’ length basis, without consideration of any control, liquidity or minority discount or premium, (b) general market conditions and comparable transactions and other generally recognized valuation methodologies, such as discounted cash flow, (c) the assumption that the closing of the Put Sale will occur seventy-five (75) days after the Put Exercise Date and any other assumptions agreed between Holdco Inc. and the Put Right Shareholder, and (d) such other factors as the Valuation Arbiter determines are relevant to its evaluation. The Put Price shall be the price set forth by Holdco Inc. or the Put Right Shareholder that is nearest to the fair market value determined by the Valuation Arbiter. In the event that the Valuation Arbiter is required to undertake an independent determination of the fair market value of the Put Shares pursuant to this Section 2.15(d)(iii), the Company, Holdco Inc. and the Put Right Shareholder shall furnish to the Valuation Arbiter all such information as the Valuation Arbiter shall reasonably request, including information concerning the Company and its assets, business, operations, affairs, financial condition or prospects, and the Valuation Arbiter shall complete any such determination of the fair market value, and provide written notice of the final Put Price as determined in accordance with this Section 2.15(d)(iii) to the Company, Holdco Inc. and the Put Right Shareholder as soon as reasonably practicable, and in any event within sixty (60) days of the Put Exercise Date.

(iv) The final Put Price as determined in accordance with this Section 2.15(d) shall be adjusted to account for any dividends or capital contributions paid during the period between the Put Exercise Date and the closing of the Put Sale, except to the extent such dividends or capital contributions were reflected in the determination of the Put Price.

(v) The determination of the final Put Price by the Valuation Arbiter in accordance with this Section 2.15(d) shall be final and binding on Holdco Inc. and the applicable Put Right Shareholder and may be entered and enforced in any court having jurisdiction.

(e) Subject to Section 2.15(h), Holdco Inc. shall, within one hundred eighty (180) days of the Put Exercise Date, give written notice to each Put Right Shareholder that Holdco Inc. has either (i) entered into a definitive acquisition agreement with a Third Party pursuant to which such Third Party shall acquire the Put Shares from such Put Right Shareholder and its Affiliates or (ii) elected to purchase, or have its Affiliate purchase, the Put Shares. Such Put Right Shareholder and Holdco Inc. and, if applicable, such Third Party Buyer, shall be required to consummate such Put Sale within the Regulatory Approval Period. In addition, Holdco Inc. and the applicable Investor Shareholder shall take all other actions as may be reasonably necessary to consummate such Put Sale, including making such representations, warranties and covenants and entering into such definitive agreements (including with third parties) as are customary for transactions of the nature of the Put Sale; provided that such Investor Shareholder shall not be required to provide any representations, warranties or covenants in connection with any Put Sale other than those representations, warranties and covenants set forth on Schedule 2.15(e). Upon the closing of a Put Sale, the purchaser of the Put Shares shall pay the Put Price, together with any amounts owed pursuant to Section 2.15(g), by wire transfer of immediately available funds to the account or accounts that the applicable Investor Shareholder shall designate to Holdco Inc. prior to such closing.

(f) The existence of a Put Triggering Event, a Put Triggering Event Notice, a Put Exercise Notice or a pending Put Sale shall not, in and of itself, relieve or excuse any Party from its ongoing duties and obligations under this Agreement.

(g) Subject to Section 2.15(h), in connection with any Put Sale by an Investor Shareholder pursuant to this Section 2.15 pursuant to which a Third Party acquires the Put Shares, Holdco Inc. shall pay such Investor Shareholder an amount equal to the Daily Ticking Fee multiplied by the number of days between the date that is sixty (60) days after the Put Exercise Date and the consummation of such Put Sale.

(h) At any time within fifteen (15) days after the determination of the final Put Price in accordance with Section 2.15(d), an Investor Shareholder may deliver written notice to Holdco Inc. and the Company that it is irrevocably withdrawing its Put Exercise Notice, and, if such notice is so delivered, such Investor Shareholder shall no longer be required to sell, and Holdco Inc. shall no longer be obligated to purchase, or arrange for the purchase of, the Put Shares or pay any Daily Ticking Fee to such Investor Shareholder in connection with such withdrawn Put Exercise Notice. Each Investor Shareholder may exercise its right to withdraw a Put Exercise Notice pursuant to this Section 2.15(h) no more than three (3) times in any sixty (60) month period. Each Investor Shareholder agrees to be responsible for the payment of one-half of the costs and expenses of the Valuation Arbiter related to any Put Exercise Notice that is withdrawn by such Investor Shareholder pursuant to this Section 2.15(h).

Section 2.4

Prohibited Payments; Prohibited Transactions.

(a) Each of the Shareholders shall, and will ensure that its respective Representatives, comply fully with all applicable anti-corruption, anti-money laundering, anti-terrorism and economic sanction and anti-boycott laws, including, without limitation, international anti-corruption conventions such as the United Nations Convention Against Bribery, and the United States Foreign Corrupt Practices Act, and in each case, any applicable implementing legislation.

(b) Each of the Shareholders has not and will not, either directly or indirectly, make a Prohibited Payment or engage in a Prohibited Transaction with respect to its obligations under this Agreement and shall ensure that none of its respective Representatives makes, either directly or indirectly, a Prohibited Payment or engages in a Prohibited Transaction with respect their respective obligations under this Agreement.

ARTICLE III

RESTRICTIONS ON TRANSFER

General Restrictions

. Each Shareholder agrees that it shall Transfer Shares, directly or indirectly, only in compliance with, and to the extent permitted by, this Agreement. For the avoidance of doubt, an “indirect” Transfer of Shares shall include any transaction or series of related transactions pursuant to which any Person becomes the Beneficial Owner of any Shares that were not Beneficially Owned by such Person immediately prior to the consummation of such transaction or transactions. Any attempted Transfer other than in strict accordance with this Agreement shall be null and void and of no force or effect whatsoever, and the purported transferee shall have no rights as a Shareholder or otherwise in or to the Shares. The Company shall not register the Transfer of any Shares made in violation of the provisions of this Agreement.

Transfers to Affiliates.

Section 3.3, Section 3.4 and Section 3.5 shall not apply to any Transfer by either Shareholder at any time of all or any portion of its Shares to any of such Shareholder’s Affiliates; provided that (a) either (i) such Transfer would not result in a Shareholder with lesser credit worthiness than the then current Shareholder (taking into account any guarantees or other credit support of the transferring Shareholder and its

proposed transferee) and the transferring Shareholder provides written notice to the other Shareholder of the Transfer at least ten (10) Business Days prior to such Transfer or (ii) the other Shareholder provides prior written consent to the Transfer, which consent shall not be unreasonably withheld, (b) any required regulatory approvals or other third-party consents or approvals are obtained prior to such Transfer and (c) such Affiliate executes a counterpart to this Agreement and agrees to be bound by all of its terms to the same extent as the transferring Shareholder. Any Affiliate who receives Shares shall Transfer such Shares back to the transferring Shareholder (or an Affiliate thereof) if at any time said Affiliate is no longer an Affiliate of such Shareholder.

Section 3.1 Right of First Offer.

(a) If a Shareholder (the “Selling Shareholder”) desires to Transfer all or any portion of its Shares to any Person other than an Affiliate of such Shareholder (a “Third-Party Purchaser”), the Selling Shareholder shall first deliver to the Company and each other Shareholder (each, a “Non-Selling Shareholder”) written notice (a “ROFO Notice”) setting forth its intent to make such Transfer and the number of Shares proposed to be Transferred (the “Offered Shares”). A Non-Selling Shareholder shall have the right to make a binding offer to purchase all, but not less than all, of the Offered Shares (or its pro rata portion of all of the Offered Shares, as applicable), by written notice (an “Offer Notice”) delivered by such Non-Selling Shareholder to the Selling Shareholder within forty-five (45) days following its receipt of a ROFO Notice (the “Offer Period”), which Offer Notice shall specify the purchase price and other material terms and conditions proposed by the Non-Selling Shareholder.

(b) The Selling Shareholder shall notify each Non-Selling Shareholder of its acceptance (an “Acceptance Notice”) or rejection (a “Rejection Notice”) of such Non-Selling Shareholder’s offer within forty-five (45) days following its receipt of an Offer Notice (the “Acceptance Period”). If the Selling Shareholder does not send an Acceptance Notice or a Rejection Notice within the Acceptance Period, the offer proposed by the Non-Selling Shareholder shall be deemed rejected by the Selling Shareholder.

(c) If the Selling Shareholder accepts the price and terms set forth in the Offer Notice delivered by a Non-Selling Shareholder within the Acceptance Period, then such Non-Selling Shareholder shall be required to enter into a definitive agreement to purchase all such Offered Shares covered by such Offer Notice within ten (10) Business Days following its receipt of the Acceptance Notice, with such purchase to be consummated within the Regulatory Approval Period. In addition, each Shareholder shall take all other actions as may be reasonably necessary to consummate such purchase and sale, including entering into such additional agreements as may be necessary or appropriate.

(d) If a Non-Selling Shareholder does not deliver an Offer Notice to the Selling Shareholder during the Offer Period with respect to any Offered Shares, or if the Selling Shareholder delivers to a Non-Selling Shareholder a Rejection Notice or fails to deliver to a Non-Selling Shareholder an Acceptance Notice or a Rejection Notice within the Acceptance Period with respect to any Offered Shares, the Selling Shareholder shall be free to Transfer all but not less than all of such Offered Shares to a Third-Party Purchaser; provided that (i) if an Offer Notice was delivered by a Non-Selling Shareholder to the Selling Shareholder during the

Offer Period with respect to any Offered Shares, the Transfer of such Offered Shares must be effected at a higher price than the price contained in the Offer Notice and on terms and conditions that are no less favorable, in the aggregate, to the Selling Shareholder, taking into account, in the case of a Selling Shareholder that is an Investor Shareholder, any concurrent sale of any other equity interest in the Companies Beneficially Owned by such Selling Shareholder or its Affiliates, than the terms and conditions set forth in the applicable Offer Notice (excepting the inclusion of customary representations and warranties given to the Third-Party Purchaser that would not customarily be given to an existing shareholder), (ii) the Selling Shareholder must enter into a definitive agreement with respect to the Transfer of such Offered Shares within one hundred eighty (180) days following the expiration of the applicable Offer Period (if the applicable Non-Selling Shareholder did not deliver an Offer Notice to the Selling Shareholder during the Offer Period) or within one hundred eighty (180) days following the earlier of (x) the applicable Non-Selling Shareholder’s receipt of a Rejection Notice or (y) the expiration of the Acceptance Period, as applicable (if the applicable Offer Notice was delivered by a Non-Selling Shareholder to the Selling Shareholder during the Offer Period) and (iii) the Transfer of such Offered Shares must be consummated within the Regulatory Approval Period. If the Transfer of such Offered Shares has not been consummated within the Regulatory Approval Period, such Offered Shares shall again become subject to all restrictions of this Section 3.3.

Section 3.2 Drag Along Rights.

(b) Following satisfaction of its obligations pursuant to Section 3.3, Holdco Inc. may exercise its Drag Along Right pursuant to this Section 3.4 by providing written notice of its election to do so to each Investor Shareholder (a “Drag Along Notice”), which

(c) The Drag Along Sale must be consummated within the Regulatory Approval Period applicable to the Transfer by Holdco Inc. to the Drag Along Purchaser. No Investor Shareholder shall Transfer or agree to Transfer any Shares to any Person other than the Drag Along Purchaser during the period between the date it receives a Drag Along Notice and the conclusion of such Regulatory Approval Period. If the Drag Along Sale shall not have been consummated during such Regulatory Approval Period, all the restrictions on Transfer contained in this Agreement or otherwise applicable at such time with respect to the Shares owned by the Shareholders shall again be in effect.

(d) In connection with any exercise of its Drag Along Right pursuant to this Section 3.4, Holdco Inc. shall pay each Investor Shareholder an amount equal to the Daily Ticking Fee multiplied by the number of days between the date that is three hundred (300) days after the date of the Drag Along Notice and the consummation of the Drag Along Sale, solely to extent such payments are necessary to ensure that the Investor Shareholder receives a per Share price equal to the Drag Along Minimum Price in effect as of the date of the consummation of the Drag Along Sale.

(e) In the event that Holdco Inc. exercises its Drag Along Right pursuant to this Section 3.4, the Investor Shareholders shall take all actions as may be reasonably necessary to consummate the Drag Along Sale, including making the representations, warranties and covenants set forth on Schedule 3.4(d) and entering into such definitive agreements as are customary for transactions of the nature of the proposed Transfer. Notwithstanding anything herein to the contrary, the Investor Shareholders agree to (i) vote in favor of the transaction or transactions with the Drag Along Purchaser, (ii) take such other action as may be required to effect such transaction and (iii) take all actions to waive any dissenters, appraisal or other similar rights with respect thereto.

Section 3.3 Tag Along Rights.

(a) In the event that Holdco Inc. desires to Transfer, in any single transaction or series of related transactions, an amount of its Shares equal to or greater than two percent (2%) of the total Shares outstanding to any Third-Party Purchaser, and Holdco Inc. cannot or has not elected to exercise any Drag Along Right it may have with respect to such Transfer pursuant to Section 3.4, each Investor Shareholder shall have the right (a “Tag Along Right”) to participate in such Transfer and require that a pro rata portion or, if as a result such transaction or series of transactions Holdco Inc.’s Pro Rata Percentage would be less than or equal to fifty percent (50%), all of its Shares be Transferred to such Third-Party Purchaser in accordance with the procedures set forth in this Section 3.5 (such Transfer, a “Tag Along Sale”) at the per Share price and otherwise on the same terms and conditions as the Transfer of the Shares by Holdco Inc. to such Third-Party Purchaser; provided that, if an Investor Shareholder or any of its Affiliates exercise a tag along right with respect to its equity interests in any of the Companies Beneficially Owned by an Investor Shareholder or its Affiliates, such Investor Shareholder shall be entitled to exercise a Tag Along Right hereunder with respect to the same

pro rata percentage as applicable to the other tag along transaction, at a price per Share and other material terms and conditions that provide such Investor Shareholder with economic value for its Shares equivalent to that received by such Investor Shareholder or its Affiliates in the other tag along transaction taking into account all relevant factors and otherwise in accordance with this Section 3.5.

(b) Prior to any Transfer in connection with which an Investor Shareholder has a Tag Along Right pursuant to Section 3.5(a), and after satisfying its obligations pursuant to Section 3.3, Holdco Inc. shall deliver to such Investor Shareholder a written notice (a “Tag Along Offer Notice”) of the proposed Transfer, which notice shall identify the Third-Party Purchaser, the aggregate number of Shares the Third-Party Purchaser has offered to purchase (including whether the Third-Party Purchaser will purchase all Shares proffered), the proposed price per Share and all other material terms and conditions of the proposed Transfer.

(c) An Investor Shareholder may exercise its Tag Along Right by delivering a written notice (a “Tag Along Election Notice”) of its election to do so within ten (10) Business Days following its receipt of a Tag Along Offer Notice (the “Tag Along Offer Period”). The Tag Along Election Notice shall specify the number of Shares such Investor Shareholder desires to Transfer. If the Third-Party Purchaser will purchase all Shares proffered, such amount may be up to (or less than) the number of Shares owned by such Investor Shareholder. If the Third-Party Purchaser will not purchase all Shares proffered, then such amount may be up to (or less than) the total Shares proposed to be purchased by the Third-Party Purchaser multiplied by such Investor Shareholder’s Pro Rata Percentage. In the event that an Investor Shareholder elects to transfer less than the maximum number of Shares it has a right to Transfer pursuant to this Section 3.5(c), Holdco Inc. may Transfer such additional number of Shares to the Third-Party Purchaser as are equal to such difference.

(d) If an Investor Shareholder fails to deliver a Tag Along Election Notice within the Tag Along Offer Period, such Investor Shareholder shall be deemed to have waived its Tag Along Right with respect to such Transfer, and Holdco Inc. may make the proposed Transfer without any further obligation to such Investor Shareholder; provided that (i) such Transfer must be effected at a price per Share that is no greater than the price per Share set forth in the Tag Along Offer Notice and on terms and conditions that are no more favorable, in the aggregate, to the seller of the Shares than the terms and conditions set forth in the Tag Along Offer Notice and (ii) such Transfer must be consummated within the Regulatory Approval Period. If such Transfer shall not have been consummated during the Regulatory Approval Period, all the restrictions on Transfer contained in this Agreement or otherwise applicable at such time with respect to the Shares owned by the Shareholders shall again be in effect.

(e) In the event that an Investor Shareholder exercises its Tag Along Right pursuant to this Section 3.5, such Investor Shareholder shall take all actions as may be reasonably necessary to consummate the Tag Along Sale, including making such representations, warranties and covenants and entering into such definitive agreements as are customary for transactions of the nature of the proposed Transfer.

Change of Control

. In the event that Holdco Inc. or an Investor Shareholder desires to effect any transaction, or series of related transactions, that would result in

a Holdco Inc. Change of Control or an Investor Shareholder Change of Control, as applicable, then the provisions of Section 3.3, Section 3.4 and Section 3.5 shall apply equally to such indirect Transfer of Shares.

Other Prohibited Transfers.

Notwithstanding anything herein to the contrary, neither Shareholder shall directly or indirectly Transfer any Shares (a) to any Prohibited Transferee or (b) to the extent such Transfer would result in a violation of any contractual, governmental or regulatory arrangements or requirements of the Company or any of the Company’s Affiliates, including the Subscription Agreement. Whenever contractual, regulatory or governmental approval is required to effect a direct or indirect Transfer that would otherwise be permitted hereunder, the Parties agree to use commercially reasonable efforts to proactively obtain such approval.

Section 3.4 ROFR Transferees.

(a) Following satisfaction of its obligations pursuant to Section 3.3, a Shareholder (other than Holdco Inc.) may Transfer its Shares to a Third Party solely in compliance with this Section 3.8.

(b) At least thirty (30) days prior to entering into a definitive agreement with respect to the Transfer of Shares to a Third-Party Purchaser, a Shareholder shall provide to Holdco Inc. a list of potential purchasers. Within fifteen (15) Business Days of receiving such list, Holdco Inc. shall provide written notice to the Shareholder of the Persons on such list that constitute ROFR Transferees.

(c) If at any time thereafter the Shareholder desires to Transfer all or any portion of its Shares to a ROFR Transferee, the Shareholder shall first deliver to Holdco Inc. a written offer (a “ROFR Offer”) to sell such Shares (the “ROFR Offered Shares”) to Holdco Inc. on terms and conditions, including price, not less favorable to Holdco Inc. than those pursuant to which the Shareholder proposes to sell such ROFR Offered Shares to the ROFR Transferee. The ROFR Offer shall disclose the identity of the ROFR Transferee, the number of ROFR Offered Shares proposed to be sold, the terms and conditions, including price, of the proposed sale and any other material facts relating to the proposed sale. Holdco Inc. shall have the right to purchase all or any part of the ROFR Offered Shares on the same terms and conditions as specified in the ROFR Offer (provided that if the consideration for such ROFR Offered Shares is other than cash, Holdco Inc. shall have the option to substitute cash at the fair market value of any such non-cash consideration), by written notice (the “ROFR Exercise Notice”) delivered to the Shareholder within forty-five (45) days following its receipt of a ROFR Offer (the “ROFR Offer Period”); provided that, if any Affiliate of Holdco Inc. exercises a right of first refusal with respect to any other equity interest in the Companies Beneficially Owned by an Investor Shareholder or its Affiliates and Holdco Inc. does not concurrently exercise its right of first refusal under this Section 3.8, Holdco Inc. shall be deemed to have exercised its right of first refusal hereunder, at a price per Share and other material terms and conditions that provide such Investor Shareholder with economic value for its Shares equivalent to that received by such Investor Shareholder or its Affiliates in the other right of first refusal transactions taking into account all relevant factors, and otherwise in accordance with this Section 3.8. If Holdco Inc. exercises its right of first refusal by delivering the ROFR Exercise Notice within the ROFR Offer

Period, Holdco Inc. and the Shareholder shall have ten (10) Business Days after it gives such ROFR Exercise Notice to enter into a definitive agreement for Holdco Inc. to purchase and the Investor Shareholder to sell such ROFR Offered Shares, with such purchase and sale to be consummated within the Regulatory Approval Period.

(d) If Holdco Inc. does not deliver a ROFR Exercise Notice to the Investor Shareholder during the ROFR Offer Period with respect to any ROFR Offered Shares or notifies the Shareholder in writing that it does not wish to purchase the ROFR Offered Shares, the Shareholder shall be free to Transfer all but not less than all of such ROFR Offered Shares to the ROFR Transferee; provided that (i) the Transfer of such ROFR Offered Shares must be effected at a price equal to or higher than the price contained in the Offer Notice and on terms and conditions that are no less favorable, in the aggregate, to the Shareholder than the terms and conditions set forth in the applicable ROFR Offer (excepting the inclusion of customary representations and warranties given to the Proposed Transferee that would not customarily be given to Holdco Inc.), (ii) the Shareholder must enter into a definitive agreement with respect to the Transfer of such ROFR Offered Shares within one hundred eighty (180) days following the expiration of the applicable ROFR Offer Period (if Holdco Inc. did not deliver a ROFR Exercise Notice to the Shareholder during the ROFR Offer Period) and (iii) the Transfer of such Offered Shares must be consummated within the Regulatory Approval Period. If the Transfer of such Offered Shares has not been consummated within the Regulatory Approval Period, such Offered Shares shall again become subject to all restrictions of this Section 3.8.

Binding Effect on Transferees.

Notwithstanding anything herein to the contrary, prior to the Transfer by a Shareholder of Shares (or any other securities exercisable, exchangeable or convertible into Shares) to any Person (including an Affiliate), other than a Transfer of all outstanding Shares, the transferring Shareholder shall cause the transferee to execute and deliver such documents as may be necessary to make such Person a party hereto and pursuant to which such Person agrees to be bound by the same terms and conditions set forth herein effective on the date of the Transfer of the Shares. In the event that a Shareholder Transfers less than all of its Shares to a Third-Party Purchaser in accordance with this ARTICLE III, the Shareholders and the Company shall negotiate in good faith to amend this Agreement to the extent reasonably necessary to reflect the addition of such Shareholder.

ARTICLE IV

CAPITAL CONTRIBUTIONS; THIRD-PARTY INVESTORS

Issuance of Additional Shares.

Except for Shares issued in accordance with Section 4.2 and Section 4.3, the Company shall not, and the Shareholders shall take all actions as may be reasonably necessary to ensure that the Company does not, issue any new Shares, or any securities convertible into Shares (“New Shares”), to any Person other than the Shareholders (such other Person, a “Third-Party Investor”) or to the Shareholders other than in accordance with their respective Pro Rata Percentages. For the avoidance of doubt, any New Shares issued in accordance with this ARTICLE IV shall be subject to the terms and conditions of this Agreement to the same extent as any Shares outstanding as of the date hereof.

Section 4.1 Additional Capital Contributions.

(a) In the event that the Company has additional funding needs other than those addressed by the Subscription Agreement, the Board may determine to request that the Shareholders make additional capital contributions to the Company (each, an “Additional Capital Contribution”) and authorize the issuance of New Shares in connection therewith (“ACC Shares”) in accordance with the procedures set forth in this Section 4.2. For the avoidance of doubt, neither Shareholder shall have any obligation to make Additional Capital Contributions to the Company pursuant to this Section 4.2.

(b) If the Board determines to request that the Shareholders make Additional Capital Contributions to the Company, the Company shall issue a written request (a “Capital Call”) to each of the Shareholders for the making of such Additional Capital Contributions. The Capital Call shall specify (i) the book value per Share, (ii) the total amount of Additional Capital Contributions requested from all Shareholders, (iii) the total number of ACC Shares proposed to be issued to the Shareholders in connection therewith (which number shall be based on the book value per Share), (iv) the amount of the Additional Capital Contribution requested from each Shareholder (with respect to each Shareholder, its “Proportionate Contribution Entitlement”), (v) the number of ACC Shares proposed to be issued to each Shareholder in connection therewith and (vi) whether the purpose of such Capital Call is to fund Necessary Expenses required by the Company during the Contribution Option Period and which the Company reasonably anticipates are in excess of the funds reasonably available to the Company from other sources, together with a brief description of any such Necessary Expenses and the other sources of funding considered but which were unavailable.

(c) The total amount of Additional Capital Contributions requested pursuant to a Capital Call and each Shareholder’s Proportionate Contribution Entitlement shall be calculated so as to ensure that, if each Shareholder made an Additional Capital Contribution in the full amount of its Proportionate Contribution Entitlement, the ACC Shares issued would not result in any change to either Shareholder’s Pro Rata Percentage. Each Shareholder acknowledges that by declining to make an Additional Capital Contribution pursuant to a Capital Call in the full amount of such Shareholder’s Proportionate Contribution Entitlement, its Pro Rata Percentage may be diluted in accordance with the terms of this Section 4.2, unless otherwise agreed by the Parties.

(d) Within forty-five (45) days following receipt of a Capital Call (the “Contribution Option Period”), each Shareholder shall send a written notice to the Company either (i) declining to make an Additional Capital Contribution pursuant to the Capital Call or (ii) agreeing to make part or all of the Shareholder’s Proportionate Contribution Entitlement and stating what portion of the Shareholder’s Proportionate Contribution Entitlement it shall make. Any Shareholder that does not send a notice within the Contribution Option Period shall be deemed to have declined to make any Additional Capital Contribution pursuant to the Capital Call.

(e) Within five (5) Business Days following the expiration of the Contribution Option Period, the Company shall give written notice (a “Contribution Notice”) to each Shareholder specifying the amount of each Shareholder’s Proportionate Contribution

Entitlement and the amount of the Additional Capital Contribution that each Shareholder agreed to make. In the event that one Shareholder does not elect to make an Additional Capital Contribution in the full amount of its Proportionate Contribution Entitlement (a “Non-Contributing Shareholder”) and the other Shareholder does elect to make an Additional Capital Contribution in the full amount of its Proportionate Contribution Entitlement (a “Contributing Shareholder”), then such Contributing Shareholder shall have the right to increase the amount of its Additional Capital Contribution to include all or any portion of the Non-Contributing Shareholder’s Proportionate Contribution Entitlement that the Non-Contributing Shareholder declined to make (such amount, a “Residual Contribution Amount”).

(f) Within ten (10) Business Days following receipt of a Contribution Notice showing a Residual Contribution Amount (the “Residual Exercise Period”), any Contributing Shareholder shall send a written notice to the Company either (i) declining to increase the amount of its Additional Capital Contribution to include any portion of the Residual Contribution Amount or (ii) exercising its right to increase its Additional Capital Contribution and stating the portion of the Residual Contribution Amount by which it desires to increase its Additional Capital Contribution. If such Shareholder does not send a notice within the Residual Exercise Period, it shall be deemed to have waived its right to increase the amount of its Additional Capital Contribution pursuant to Section 4.2(e).

(g) At the expiration of the Contribution Option Period or the Residual Exercise Period, as applicable, any Shareholder electing to make an Additional Capital Contribution pursuant to Section 4.2(d) and Section 4.2(f) (an “Electing Shareholder”) may make such Additional Capital Contribution and the Company may issue ACC Shares in connection therewith without any further obligation to any other Shareholder. Any Electing Shareholder shall make such Additional Capital Contribution within ten (10) Business Days following its receipt of a Contribution Notice or within ten (10) Business Days following the receipt of any and all required regulatory approvals, whichever is later (such date, the “ACC Deadline”), and the Company shall issue ACC Shares in connection therewith as promptly as practicable thereafter. In addition, the Company and any Electing Shareholder shall take all such other actions as may be reasonably necessary to complete such Additional Capital Contribution, including entering into such additional agreements as may be necessary or appropriate.

(h) With respect to any Capital Call to fund Necessary Expenses required by the Company during the Contribution Option Period and for which the Company reasonably anticipates are in excess of the funds reasonably available to the Company from other sources, any Shareholder may elect to contribute part or all of its and any other Shareholder’s Proportionate Contribution Entitlement of the Additional Capital Contributions in respect of the related request therefor (collectively, the “Emergency Advance”) and such Emergency Advance will be treated as a loan from such Shareholder to the Company, provided that a Shareholder must notify the other Shareholders in writing of the amount of such Emergency Advance at least five (5) Business Days prior to the contribution thereof (the “Emergency Advance Notice”). If a Shareholder has elected to contribute all or part of its or another Shareholder’s Proportionate Contribution Entitlement pursuant to this Section 4.2(h), upon contribution of the Proportionate Contribution Amounts by each Shareholder as an Additional Capital Contribution, the Company shall pay directly to the Shareholder making the Emergency Advance an amount equal to the Emergency Advance made by such Shareholder plus an additional amount of interest thereon

equal to nine percent (9%) per annum from the date of the Emergency Advance to the date of repayment of such Emergency Advance, and, provided, further, if the other Shareholders do not elect to contribute to the Company its pro rata share of the amount of the Emergency Advance (together with interest thereon as aforesaid), then the amount such Shareholder has contributed (including both its and any other Shareholders’ portion thereof), including interest thereon as aforesaid, will be designated as an Additional Capital Contribution and the Company may issue ACC Shares in connection therewith without any further obligation to any other Shareholder.

Section 4.2 Third-Party Investors.

(a) In the event that, following the ACC Deadline, the Company has not received Additional Capital Contributions from the Shareholders in the full amount of the Additional Capital Contributions requested pursuant to a Capital Call, the Board may, in accordance with Section 2.8, authorize the Company to seek additional equity funds from Third-Party Investors in an amount up to the difference between the total Additional Capital Contributions requested and the total Additional Capital Contributions received, and to issue New Shares to Third-Party Investors in connection therewith pursuant to this Section 4.3.

(b) If the Board determines to seek additional equity funds from and issue New Shares to Third-Party Investors pursuant to Section 4.3(a), (i) the Company must enter into a definitive agreement with respect to such issuance within one hundred eighty (180) days following the ACC Deadline and (ii) such issuance must be completed within the Regulatory Approval Period. If such issuance has not been completed within the Regulatory Approval Period, the Company shall not thereafter issue any New Shares to Third-Party Investors without first complying with all of the provisions of Section 4.2. Upon completion of any such issuance of New Shares to a Third-Party Investor, the Company shall give written notice to the Shareholders of such issuance, which notice shall specify (x) the total number of New Shares issued, (y) the price per Share at which the Company issued the New Shares and (z) any other material terms of the issuance.

(c) In the event that the Company issues New Shares to one or more Third-Party Investors pursuant to this ARTICLE IV, the Shareholders and Company shall negotiate in good faith to amend this Agreement to the extent reasonably necessary to reflect such additional Shareholders.

Subscription Agreement

. The Parties acknowledge and agree that nothing in this Agreement shall be construed to affect or limit the capital contribution procedures set forth in Article II of the Subscription Agreement.

ARTICLE V

DIVIDENDS

Dividends.

Except as otherwise provided herein, and subject to Section 2.9(a) and the IBCL, dividends on Shares shall be made if and at such times and in such amounts as the Board shall determine by the affirmative vote of a majority of the Directors present at a duly convened meeting of the Board at which a quorum is present. All dividends on

Shares shall be made in cash. Any dividends on Shares shall be subject to the maintenance by the Company of working capital requirements and prudent reserves (as determined by the Board), including reserves for the payment of future expenses, costs, capital requirements and other obligations of the Company, and subject to applicable fiduciary duties, law (including the IBCL), regulatory requirements and the terms of any agreements providing for debt financing in respect of the Company. All dividends on Shares shall be paid to each Shareholder in accordance with its Pro Rata Percentage, provided that, in the case of dividends on Shares to be paid in respect of any fiscal quarter during which the Pro Rata Percentages of the Shareholders changed, such dividends shall be prorated to reflect the Pro Rata Percentage of each Shareholder on each day of such fiscal quarter, and the Company and the Shareholders shall take such action as necessary to effectuate such proration.

Limitations on Dividends.

Notwithstanding any provision to the contrary contained in this Agreement, the Company shall not make a distribution to any Shareholder on account of its Shares if such dividend would violate the IBCL or other applicable law or any of the terms of any agreements in respect of the Company.

Severability.

Any term or provision of this Agreement that is determined by a court of competent jurisdiction to be invalid or unenforceable for any reason shall, as to that jurisdiction, be ineffective solely to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is determined by a court of competent jurisdiction to be so broad as to be unenforceable, that provision shall be interpreted to be only so broad as is enforceable.

Assignment; Third-Party Beneficiaries.

Except as otherwise provided herein, all the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the respective successors and permitted assigns of the Parties. Neither Shareholder, nor the Company, shall purport to assign or Transfer all or any of its rights or obligations under this Agreement nor grant, declare, create or dispose of any right or interest in this Agreement in whole or in part except with respect to a Transfer in accordance with the terms of this Agreement. This Agreement is not intended to confer any rights or remedies hereunder upon any other Person except the Parties, it being for the exclusive benefit of the Parties and their respective successors and permitted assigns. Persons other than the Parties may not rely upon the representations and warranties in this Agreement as characterizations of actual facts or circumstances as of the date of this Agreement or as of any other date.

Amendments.

This Agreement may be amended, modified or supplemented, with respect to any of the terms contained in this Agreement, only by written agreement (referring specifically to this Agreement) signed by or on behalf of all of the Parties; provided, however, that the Company shall amend this Agreement pursuant to Section 1.2 without any further action by the Parties as necessary to reflect accurately the information therein and to add any other Persons who acquire Shares.

Waiver.

No waiver of any breach of any of the terms of this Agreement shall be effective unless such waiver is made expressly in an instrument in writing specifically referring to this Agreement and executed and delivered by the Party against whom such waiver is claimed. No waiver of any breach shall be deemed to be a further or continuing waiver of such breach or a waiver of any other or subsequent breach. Except as otherwise expressly provided herein, no failure on the part of any Party to exercise, and no delay in exercising, any right, power or remedy hereunder, or otherwise available in respect hereof at law or in equity, shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power or remedy by such party preclude any other or further exercise thereof, or the exercise of any other right, power or remedy. The rights and remedies of the Parties under this

Agreement are cumulative and are in addition to, and not in substitution for, any other rights and remedies available at law or in equity or otherwise.

Section 11.2 Interpretation.

(a) When a reference is made in this Agreement to an Article, Section, clause or Exhibit, such reference shall be to an Article, Section or clause of, or Exhibit to, this Agreement unless otherwise indicated, and the words “Agreement,” “hereby,” “herein,” “hereof,” “hereunder” and words of similar import refer to this Agreement as a whole (including any Exhibits) and not merely to the specific section, paragraph or clause in which such word appears. The table of contents and the Article and Section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and do not in any way affect the meaning or interpretation of this Agreement. The phrases “the date of this Agreement,” “the date hereof” and terms of similar import, shall be deemed to refer to February 11, 2015. References to any statute are to that statute, as amended from time to time, and to the rules and regulations promulgated thereunder. Unless otherwise expressly provided herein, references to any agreement or document shall be a reference to such agreement or document as amended, modified or supplemented and in effect from time to time and shall include reference to all exhibits, schedules and other documents or agreements attached thereto or incorporated therein, including waivers or consents. Unless otherwise expressly provided herein, references to any Person include the successors and permitted assigns of that Person. Whenever the content of this Agreement permits, the masculine gender shall include the feminine and neuter genders, and a reference to singular or plural shall be interchangeable with the other. References from or through any date mean, unless otherwise specified, from and including or through and including, respectively. As used in this Agreement: (i) the term “including” and words of similar import mean “including, without limitation” unless otherwise specified, (ii) “$” and “dollars” refer to the currency of the United States of America, (iii) “or” shall include both the conjunctive and disjunctive and (iv) “any” shall mean “one or more”. Unless the defined term “Business Days” is used, references to “days” in this Agreement refer to calendar days.

(b) The Parties have participated jointly in negotiating and drafting this Agreement. In the event that an ambiguity or a question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the authorship of any provision of this Agreement.

(c) No summary of this Agreement prepared by or on behalf of any Party shall affect the meaning or interpretation of this Agreement.

Governing Law.

This Agreement, the legal relations between the Parties hereto and the adjudication and the enforcement thereof, shall be governed by and interpreted and construed in accordance with the substantive laws of the State of New York, without regard to applicable choice of law provisions thereof.

Specific Performance.

The Parties agree that irreparable harm would occur and the Parties would not have any adequate remedy at law in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or

were otherwise breached. It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which they are entitled at law or in equity, all in accordance with Section 11.18. The Parties hereby waive, in any action for specific performance, the defense of adequacy of a remedy at law and the posting of any bond or other undertaking or security in connection therewith. Each Party further agrees that (a) by seeking any remedy provided in this Section 11.12, a Party shall not in any respect waive its right to seek any other form of relief that may be available to a Party under this Agreement and (b) nothing contained in this Section 11.12 shall require any Party to institute any action for (or limit any Party’s right to institute any action for) specific performance under this Section 11.12 prior to exercising any other right under this Agreement.

Counterparts.

This Agreement may be executed in two or more counterparts, each of which shall be deemed an original but all of which shall constitute one (1) and the same Agreement.

Recapitalizations, Exchanges, Etc.; New Shares.

The provisions of this Agreement shall apply, to the full extent set forth herein with respect to Shares and to any and all equity or debt securities of the Company or any successor or assign of the Company (whether by merger, consolidation, Transfer of assets, or otherwise) which may be issued in respect of, in exchange for, or in substitution of, such Shares and shall be appropriately adjusted for any stock dividends, splits, reverse splits, combinations, reclassifications, recapitalizations, reorganizations and the like occurring after the date hereof.

Corporate Opportunities.

The Company and each Shareholder expressly acknowledge and agree that (a) neither of the Shareholders nor any of their respective Affiliates or Representatives shall have any duty to communicate or present an investment or business opportunity to the Company in which the Company may, but for the provisions of this Section 11.15, have an interest or expectancy (a “Corporate Opportunity”), and (b) neither of the Shareholders nor any of their respective Affiliates or Representatives (even if such Person is also an officer or Director of the Company) shall be deemed to have breached any fiduciary or other duty or obligation to the Company by reason of the fact that any such Person pursues or acquires a Corporate Opportunity for itself or directs, sells, assigns or transfers such Corporate Opportunity to another Person or does not communicate information regarding such Corporate Opportunity to the Company. The Company expressly renounces any interest in a Corporate Opportunity and any expectancy that a Corporate Opportunity will be offered to the Company.

Section 11.3 Public Announcements.

(a) No public announcement or press release in connection with the execution or subject matter of this Agreement or the acquisition or disposition of Shares by any Person shall be made or issued by or on behalf of any Party without the prior written approval of the Shareholders, which approval shall not be unreasonably withheld.

(b) If a Party is required to make or issue any announcement required by law or any stock exchange or by any governmental authority, such Party shall give the other Parties reasonable opportunity to comment on such announcement or release before it is made or

issued (provided that opportunity to comment shall not have the effect of preventing the Party making the announcement or release from complying with its disclosure obligations).

Section 11.4 Legends.

(a) In addition to any other legend that may be required, each Share certificate issued to any Shareholder shall bear a legend in substantially the following form:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”) AND MAY NOT BE SOLD, ASSIGNED OR OTHERWISE TRANSFERRED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR AN EXEMPTION THEREFROM IS AVAILABLE.

THE SALE, ASSIGNMENT OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE HOLDER HEREOF OR HIS PREDECESSOR IN INTEREST. COPIES OF SUCH AGREEMENT MAY BE OBTAINED BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS SECURITY TO THE SECRETARY OF THE COMPANY.

(b) If any Shares are registered under the Securities Act, then the Company, upon the written request of the holder thereof, shall issue to such holder a new certificate evidencing such Shares without the first sentence of the legend set forth above endorsed thereon. If any Shares cease to be subject to any and all restrictions on Transfer set forth in this Agreement, the Company, upon the request of the written holder thereof, shall issue to such holder a new certificate evidencing such Shares without the second and third sentences of the legend set forth above endorsed thereon.

Section 11.5 Dispute Resolution.

(a) Except as otherwise provided by this Agreement, any dispute, controversy or claim arising out of or in connection with, or relating to, this Agreement or any breach or alleged breach hereof (which breach or alleged breach by a Party remains uncured within ten (10) Business Days after receipt of written notice thereof from another Party) or the validity or termination hereof (a “Dispute”) shall first be settled as far as possible by negotiations between the parties to the Dispute, in the form of meetings between senior-management level representatives of such parties, upon the written request by any such party to the other parties to the Dispute.

(b) If the parties to the Dispute are unable for any reason to resolve a Dispute within thirty (30) days after receipt by any Party of written notice of a Dispute, then any Party may submit the Dispute to arbitration to be finally and exclusively resolved under the Arbitration Rules of the International Chamber of Commerce then in effect (the “Rules”), except as modified herein. There shall be three (3) arbitrators. If there are two (2) parties to the Dispute, each of the parties to the Dispute shall nominate one (1) arbitrator in accordance with

the Rules. If there are more than two (2) parties to the Dispute, the arbitrators shall be nominated in accordance with the Rules; provided, however, that any Party and its Affiliates shall be entitled to nominate only one (1) such arbitrator. The arbitrators so nominated, once confirmed by the International Court of Arbitration of the International Chamber of Commerce (the “ICC Court”), shall nominate an additional arbitrator to serve as chairman, such nomination to be made within fifteen (15) days of the confirmation by the ICC Court of the second arbitrator. If the initial arbitrators shall fail to nominate an additional arbitrator within such fifteen (15) day period, such additional arbitrator shall be appointed by the ICC Court. The arbitrators shall be required to submit a written statement of their findings and conclusions. Except as otherwise agreed by the parties to such Dispute, exclusive venue of arbitration shall be New York, New York, and the language of the arbitration shall be English and each of the Parties hereby submits to the non-exclusive jurisdiction of the state and federal courts located in New York, New York for preliminary relief in aid of arbitration and for the enforcement of any arbitral award. By agreeing to arbitration, the Parties do not intend to deprive any national court of its jurisdiction to issue any pre-arbitral injunction, pre-arbitral attachment or other order in aid of arbitration proceedings.

(c) None of the Parties or the arbitrators shall select any arbitrator for the arbitral tribunal who has any interest in the Dispute or who has, or within the immediately preceding five (5) years has had, any economic or other relationship with any party to the Dispute.

(d) The arbitrators shall not have the right to award consequential, incidental, indirect, special, treble, multiple or punitive damages. The arbitral tribunal shall not be empowered to decide any dispute ex aequo et ▇▇▇▇ or amiable compositeur. The arbitration award shall be decided by majority opinion and issued in writing in the English language and shall state the reasons upon which it is based. It may be made public only with the consent of each participating Party or as may be required by law or regulatory authority or as necessary for enforcement of such award. The arbitrators shall allocate the fees and costs of the arbitration. The losing Party(ies) shall pay the prevailing Party(ies)’ attorney’s fees and costs and the costs associated with the arbitration, including the expert fees and costs and the arbitrators’ fees and costs borne by the prevailing Party(ies), all as determined by the arbitrators. Each Party shall bear its own fees and costs until the arbitrators determine which, if any, Party is the prevailing Party(ies) and the amount that is due to such prevailing Party(ies).

(e) The award rendered by the arbitrators shall be final and binding on the participating Parties and shall be the sole and exclusive remedy between and among the participating Parties regarding any claims, counterclaims, issues or accounting presented to the arbitral tribunal. The award shall be issued no later than one hundred twenty (120) days from the signing or ratification of the Terms of Reference (as defined in the Rules) or as soon thereafter as practicable. The award shall be paid within thirty (30) days after the date it is issued and shall be paid in U.S. Dollars in immediately available funds, free and clear of any Liens, Taxes or other deductions. A judgment confirming or enforcing such award may be rendered by any court of competent jurisdiction.

(f) The arbitration shall be confidential. No Party may disclose the fact of the arbitration, any award relating thereto or any settlement relating to any Dispute without the

prior consent of the other Party(ies); provided, that such matters may be disclosed without the prior consent of the other Party(ies) to lenders, auditors, Tax or other governmental authority or as may be required by law or regulatory authorities or as necessary to enforce any award.

(g) Notwithstanding the existence of any Dispute, the Parties shall continue to perform their respective obligations under this Agreement unless the Parties otherwise mutually agree in writing. Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement is intended to, nor shall it, prevent the Parties from seeking temporary injunctive relief at any time as may be available under Law or in equity to preserve its rights pending the outcome of any arbitration. Without prejudice to such provisional remedies as may be available under the jurisdiction of a national court, the arbitral tribunal shall have full authority to grant provisional remedies or order the Parties to request that a court modify or vacate any temporary or preliminary relief issued by a court, and to award damages for the failure of any Party to respect the arbitral tribunal’s orders to that effect. The Parties agree that any issue regarding the arbitrability of any claims or disputes arising under, relating to or in connection with this Agreement is an issue solely for the arbitrators, not a court, to decide.

(h) THE PARTIES HEREBY EXPRESSLY WAIVE ALL RIGHTS TO TRIAL BY JURY OR OTHERWISE ON ANY CLAIM, CAUSE OF ACTION, SUIT OR PROCEEDING PERMITTED UNDER THIS SECTION 11.18. THE PROVISIONS OF THIS AGREEMENT RELATING TO WAIVER OF TRIAL BY JURY SHALL SURVIVE THE TERMINATION OR EXPIRATION OF THIS AGREEMENT.
