Section 3.2 Exchange of Shares and Certificates.

(a) Exchange Agent. Prior to the Effective Time, Orion and Diamond shall mutually designate a bank, trust company or nationally recognized stockholder services provider (the “Exchange Agent”) for the purpose of exchanging, in accordance with this Article III, Certificates and Book-Entry Shares for the Merger Consideration. In addition, at or prior to the

Effective Time, HoldCo shall, and Diamond and Orion shall cause HoldCo to, deposit or cause to be deposited with the Exchange Agent for the benefit of the holders of shares of Diamond Common Stock and the holders of shares of Orion Common Stock evidence of shares of HoldCo Common Stock representing the aggregate amount of shares of HoldCo Common Stock sufficient to deliver the Merger Consideration (such shares, together 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.

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a certificate (an “Orion Certificate”) or book-entry share (an “Orion Book-Entry Share”) that immediately prior to the Effective Time represented outstanding shares of Orion Common Stock, as applicable, and to each holder of record of a certificate (a “Diamond Certificate” and, together with an Orion Certificate, a “Certificate”) or book-entry share (a “Diamond Book-Entry Share” and, together with an Orion Book-Entry Share, a “Book-Entry Share,”) that immediately prior to the Effective Time represented outstanding shares of Diamond Common Stock, as applicable, whose shares were converted into the right to receive the applicable Merger Consideration, (i) 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 HoldCo may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates and Book-Entry Shares in exchange for the applicable 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 HoldCo, 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 HoldCo Common Stock and/or cash, as applicable, 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 canceled. If any portion of the applicable Merger Consideration is to be registered in the name of 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 of such Merger Consideration that the surrendered Certificate 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. 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 applicable Merger Consideration. No interest shall be paid or shall accrue for the benefit of holders of Certificates or Book-Entry Shares on the applicable 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 HoldCo 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 HoldCo 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 the effect of Applicable Laws, following surrender of any such Certificate or Book-Entry Share, there shall be paid to the holder of shares of HoldCo 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 HoldCo Common Stock to which such holder is entitled pursuant to Section 3.2(e) and the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such shares of HoldCo Common Stock, and (ii) 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 HoldCo Common Stock.

(d) No Further Ownership Rights in Orion Common Stock, Diamond Common Stock and Diamond Series A Preferred Stock. All shares of HoldCo Common Stock issued upon the surrender for exchange of Certificates or Book-Entry Shares in accordance with the terms of this Article III shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to the shares of Orion Common Stock, Diamond Common Stock or Diamond Series A Preferred Stock, as applicable, theretofore represented by such Certificates or Book-Entry Shares, subject, however, to the obligation of HoldCo to pay any dividends or make any other distributions with a record date prior to the Effective Time that may have been declared or made by Orion or Diamond, as applicable, on such shares of Orion Common Stock, Diamond Common Stock or Diamond Series A Preferred Stock in accordance with the terms of this Agreement and that remain unpaid at the Effective Time, and there shall be no further registration of transfers on the stock transfer books of the Orion Surviving Corporation of the shares of Orion Common Stock, or the Diamond Surviving Corporation of the shares of Diamond Common Stock or Diamond Series A Preferred Stock, that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates or Book-Entry Shares are presented to HoldCo or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Article III, except as otherwise provided by law.

(e) Fractional Shares.

(i) No certificates representing fractional shares of HoldCo Common Stock shall be issued upon the surrender for exchange of Certificates or Book-Entry Shares, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of HoldCo.

(ii) Notwithstanding any other provision of this Agreement, each holder of shares of Orion Common Stock converted pursuant to either Merger who would otherwise have been entitled to receive a fraction of a share of HoldCo Common Stock (after taking into account all Certificates and Book-Entry Shares delivered by such holder) shall receive, in lieu thereof, cash (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 HoldCo Common Stock delivered to the Exchange Agent by HoldCo for issuance to holders of Certificates or Book-Entry Shares over (ii) the aggregate number of full shares of HoldCo Common Stock to be distributed to holders of Certificates or Book-Entry Shares (such excess being herein referred to as 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 NYSE, all in the manner provided herein.

(iii) The sale of the Excess Shares by the Exchange Agent shall be executed on the NYSE 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 holders of Certificates or Book-Entry Shares, the Exchange Agent shall hold such proceeds in trust for such holders. 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, 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 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).

(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 HoldCo, 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 HoldCo for payment of their claim for any shares of HoldCo Common Stock, any Cash Consideration, any cash in lieu of fractional shares of HoldCo Common Stock and any dividends or distributions with respect to HoldCo Common Stock.

(g) No Liability. None of Orion, Diamond, HoldCo, Orion Merger Sub, the Orion Surviving Corporation, Diamond Merger Sub, the Diamond 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 cash, any shares of HoldCo Common Stock, any cash in lieu of fractional shares of HoldCo Common

Stock or any dividends or distributions with respect to HoldCo Common Stock in respect of such Certificate or Book-Entry Share would otherwise escheat to or become the property 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 HoldCo, free and clear of all claims or interests of any person previously entitled thereto.

(h) Investment of Merger Consideration. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by HoldCo, provided, that no losses on such investments shall affect the cash payable to former holders of shares of Orion Common Stock or shares of Diamond Common Stock pursuant to this Article III. Any interest and other income resulting from such investments shall be paid to HoldCo.

(i) Withholding Rights. Each of HoldCo 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.

(j) 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 HoldCo or the Exchange Agent, the posting by such person of a bond in such reasonable amount as HoldCo 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 Merger Consideration with respect to the shares of Orion Common Stock or shares of Diamond Common Stock, as applicable, formerly represented thereby, any cash in lieu of fractional shares of HoldCo Common Stock, and unpaid dividends and distributions on shares of HoldCo Common Stock deliverable in respect thereof, pursuant to this Agreement.

Section 3.3 Certain Adjustments. If between the date of this Agreement and the Effective Time, the outstanding shares of Orion Common Stock or Diamond Common Stock are changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares, dividend payable in stock or other securities or other similar transaction, the Orion Exchange Ratio and related provisions shall be appropriately adjusted to provide to the holders of Orion Common Stock and Diamond Common Stock or Orion Equity Awards and Diamond Equity Awards the same economic effect as contemplated by this Agreement prior to such reclassification, recapitalization, split-up, combination, exchange, dividend or other similar transaction.

Section 3.4 Further Assurances. At and after the Effective Time, the officers and directors or managers, as applicable, of HoldCo, Diamond Surviving Corporation and Orion Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of Orion or Diamond, any deeds, bills of sale, assignments or assurances and to take and do, in the

name and on behalf thereof, any other actions and things necessary to vest, perfect or confirm of record or otherwise in HoldCo, any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by HoldCo as a result of, or in connection with, the Mergers.

(d) Financing Cooperation.

(i) Subject to the limitation set forth in Section 5.1, during the period from the date of this Agreement to the Effective Time, the parties hereto shall cooperate in good faith to implement any necessary, appropriate or desirable arrangements in connection with each party’s indentures or other documents governing or relating to indebtedness with respect to any financing matters concerning Orion, Diamond and the transactions contemplated by this Agreement.

(ii) The parties hereto acknowledge and agree that, prior to the Effective Time, subject to the limitation set forth in Section 5.1, it may be necessary for Diamond and/or Orion to enter into financing transactions (including, without limitation, the raising of new financing, the refinancing of existing indebtedness, the retirement of existing indebtedness and/or producing amendments, modifications or consents in relating to existing indebtedness) (any such financing transaction, a “Pre-Merger Financing Transaction”). In connection with any Pre-Merger Financing Transaction, the parties hereto agree to cooperate and use their reasonable best efforts to provide such information to each other as may be necessary or desirable in connection with the structuring, marketing and execution of any Pre-Merger Financing Transaction, including (A) participating in meetings and due diligence sessions in connection with the

Pre-Merger Financing Transaction, (B) assisting with the preparation of any portion of the disclosure in relation to the Pre-Merger Financing Transaction that relates to the Merger or the transactions contemplated by this Agreement (including any financial information and operational data), and (C) delivering, or procuring the delivery of, such information, certificates, comfort letters, representation letters and other documents as may be necessary or desirable by any party to any such Pre-Merger Financing Transaction (including, without limitation, any investment banks appointed in any capacity with respect to any Pre-Merger Financing Transaction).

(iii) Notwithstanding anything to the contrary in this Section 5.1(d), neither Orion nor Diamond shall be required to disclose any information pursuant to this Section 5.1(d) to the extent that (A) 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, (B) in the reasonable good faith judgment of such party, the information is subject to confidentiality obligations to a third party or (C) disclosure of any such information or document would result in the loss of attorney-client privilege; provided, further, that with respect to clauses (A) through (C) of this Section 5.1(d), Orion or Diamond, as applicable, shall use its commercially reasonable 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 Orion or Diamond and (3) in the case of clauses (A) through (C), 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.

Section 5.2 No Solicitation by Orion. (a) Orion shall not, shall not authorize or permit any of its controlled affiliates or any of its or their officers, directors or employees to, and shall use its reasonable best efforts to cause any investment banker, financial advisor, attorney, accountant or other representative (a “Representative”) retained by it or any of its controlled affiliates not to, directly or indirectly through another person, (i) solicit, initiate or knowingly encourage (including by way of furnishing information), or knowingly take any other action designed to facilitate, any inquiries regarding, or the making of, any proposal the consummation of which would constitute an Orion Alternative Transaction, or (ii) participate in any discussions or negotiations, or cooperate in any way with any person (or group of persons), with respect to any inquiries regarding, or the making of, any proposal the consummation of which would constitute an Orion Alternative Transaction, except to notify such person (or group of persons) as to the existence of the provisions of this Section 5.2; provided, however, that if, at any time prior to obtaining the Orion Stockholder Approval, the Board of Directors of Orion determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) that any such proposal that did not result from a material breach of this Section 5.2(a) constitutes or could reasonably be expected to result in an Orion Superior Proposal, subject to compliance with Section 5.2(c), Orion and its Representatives may (A) furnish information with respect to Orion and its subsidiaries to the person (or group of persons) making such proposal (and its Representatives and financing sources) (provided that all such information has previously been provided to Diamond or is provided to Diamond prior to or

substantially concurrent with the time it is provided to such person) pursuant to a customary confidentiality agreement containing terms as to confidentiality (it being understood that such confidentiality agreement need not include any “standstill” terms) generally no less restrictive than the terms of the confidentiality agreement, dated November 24, 2015, as amended, entered into between Orion and Diamond (the “Confidentiality Agreement”), and (B) participate in discussions or negotiations regarding such proposal with the person (or group of persons) making such proposal (and its Representatives and financing sources). For purposes of this Agreement, “Orion Alternative Transaction” means any of (i) a transaction or series of transactions pursuant to which any person (or group of persons) other than Diamond and its subsidiaries (including HoldCo, Orion Merger Sub and Diamond Merger Sub) (such person (or group of persons), an “Orion 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 outstanding shares of Orion 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 Orion, whether from Orion or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, consolidation, share exchange or similar transaction pursuant to which any Orion Third Party acquires or would acquire, directly or indirectly, assets or businesses of Orion or any of its subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Orion and its subsidiaries taken as a whole, (iii) any transaction pursuant to which any Orion Third Party acquires or would acquire, directly or indirectly, control of assets (including for this purpose the outstanding equity securities of subsidiaries of Orion and any entity surviving any merger or combination including any of them) of Orion or any of its subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Orion and its subsidiaries taken as a whole, or (iv) any disposition of assets to an Orion Third Party representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Orion and its subsidiaries, taken as a whole.

(b) Except as permitted by this Section 5.2(b), neither the Board of Directors of Orion nor any committee thereof shall (i) withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify, or fail to make, in each case in a manner adverse to Diamond, the approval or recommendation by such Board of Directors or such committee of the Orion Merger or this Agreement, (ii) approve or recommend, or propose publicly to approve or recommend, any Orion Alternative Transaction (any action in clause (i) or this clause (ii) being referred to as an “Orion Recommendation Change”), provided, that nothing herein shall restrict or otherwise limit Orion from making accurate disclosure to its stockholders of factual information regarding the business, financial condition or results of operations of Orion or, so long as Orion provides Diamond with reasonable advance notice and a copy of the proposed disclosure, the fact that a proposal the consummation of which would constitute an Orion Alternative Transaction has been made, the identity of the party making such proposal or the material terms of such proposal (and such disclosure shall not be deemed to be an Orion Recommendation Change), so long as the disclosure through which such factual information is conveyed, taken as a whole, is not contrary to or materially inconsistent with the recommendation made by the Orion Board of Directors; or (iii) cause Orion or any of its controlled affiliates to enter into any letter of intent, agreement in principle, acquisition agreement or other agreement related to any Orion Alternative Transaction

or requiring, or reasonably likely to cause, Orion to terminate, delay or fail to consummate, or that would otherwise impede, interfere with or be inconsistent with, the consummation of the Mergers or any of the other transactions contemplated by this Agreement (other than a confidentiality agreement referred to in Section 5.2(a)). Notwithstanding the foregoing, in the event that prior to obtaining the Orion Stockholder Approval, the Board of Directors of Orion determines in good faith, after it has received an Orion 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 Orion may (subject to this and the following sentences) effect an Orion Recommendation Change, but only at a time that is after the fourth business day following Diamond’s receipt of written notice from Orion advising Diamond that the Board of Directors of Orion has received an Orion Superior Proposal specifying the material terms and conditions of such Orion Superior Proposal, identifying the person making such Orion Superior Proposal and stating that it intends to make an Orion Recommendation Change; provided that in the event of a subsequent modification to the material terms and conditions of such Orion Superior Proposal, the Board of Directors of Orion may only effect an Orion Recommendation Change after the second business day following Diamond’s receipt of written notice from Orion advising Diamond of the modification to such terms and conditions; and provided further that during such four or two business day notice period, as applicable, Orion engages (to the extent requested by Diamond) in good faith negotiations with Diamond to amend this Agreement in such a manner that the proposal to enter into an Orion Alternative Transaction no longer constitutes an Orion Superior Proposal. For purposes of this Agreement, an “Orion Superior Proposal” means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by an Orion Third Party to enter into an Orion Alternative Transaction (with all references to 20% in the definition of Orion 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), (B) is on terms that the Board of Directors of Orion determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be superior from a financial point of view to Orion’s stockholders than the transactions contemplated by this Agreement, taking into account all relevant factors (including any changes to this Agreement that may be proposed by Diamond in response to such proposal to enter into an Orion Alternative Transaction and the identity of the person making such proposal to enter into an Orion Alternative Transaction), and (C) is reasonably likely to be completed, taking into account all financial, regulatory, legal and other aspects of such proposal. In addition, notwithstanding anything in this Agreement to the contrary, at any time prior to the receipt of the Orion Stockholder Approval, if the Board of Directors of Orion 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 Orion may effect an Orion Recommendation Change in response to any Orion Intervening Event, but only at a time that is after the fourth business day following Diamond’s receipt of written notice from Orion advising Diamond of all material information with respect to any such Orion Intervening Event and stating that it intends to make an Orion Recommendation Change and providing its rationale therefor. The term “Orion Intervening Event” shall mean a material event or change in circumstance that arises or occurs after the date of this Agreement that, prior to the date of this Agreement, was neither

known nor reasonably foreseeable by the Board of Directors of Orion; provided, however, that (i) in no event shall the receipt, existence or terms of an Orion Alternative Transaction or any matter relating thereto or consequence thereof constitute an Orion Intervening Event and (ii) in no event shall any event or events that has or have an adverse effect on the business, properties, financial condition or results of operations of Diamond and its subsidiaries, taken as a whole, constitute an Orion Intervening Event unless such event or events has had or would reasonably be expected to have a Diamond Material Adverse Effect.

(c) In addition to the obligations of Orion set forth in Sections 5.2(a) and 5.2(b), Orion shall promptly, and in any event within 24 hours of receipt thereof, advise Diamond orally and in writing of any request for information or of any proposal relating to an Orion 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. Orion shall (i) keep Diamond reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a current basis and (ii) provide to Diamond as soon as reasonably practicable after receipt or delivery thereof copies of all correspondence and other written materials exchanged between Orion 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 that describes in any material respect any of the material terms or conditions of any such request or proposal.

(d) Nothing contained in this Section 5.2 shall prohibit Orion 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 an Orion Recommendation Change shall be subject to the provisions of Section 5.2(b).

Section 5.3 No Solicitation by Diamond. (a) Diamond shall not, shall not authorize or permit any of its controlled affiliates or any of its or their officers, directors or employees to, and shall use its reasonable best efforts to cause any Representatives retained by it or any of its controlled affiliates not to, directly or indirectly through another person, (i) solicit, initiate or knowingly encourage (including by way of furnishing information), or knowingly take any other action designed to facilitate, any inquiries regarding, or the making of, any proposal the consummation of which would constitute a Diamond Alternative Transaction or (ii) participate in any discussions or negotiations, or cooperate in any way with any person (or group of persons), with respect to any inquiries regarding, or the making of, any proposal the consummation of which would constitute a Diamond Alternative Transaction, except to notify such person (or group of persons) as to the existence of the provisions of this Section 5.2; provided, however, that if, at any time prior to obtaining the Diamond Stockholder Approval, the Board of Directors of Diamond determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) that any such proposal that did not result from a material breach of this Section 5.3(a) constitutes or could reasonably be expected to result in a Diamond Superior Proposal, subject to compliance with Section 5.3(c), Diamond and

its Representatives may (A) furnish information with respect to Diamond and its subsidiaries to the person (or group of persons) making such proposal (and its Representatives and financing sources) (provided that all such information has previously been provided to Orion or is provided to Orion prior to or substantially concurrent with the time it is provided to such person) pursuant to a customary confidentiality agreement containing terms as to confidentiality (it being understood that such confidentiality agreement need not include any “standstill” terms) generally no less restrictive than the terms of the Confidentiality Agreement and (B) participate in discussions or negotiations regarding such proposal with the person (or group of persons) making such proposal (and its Representatives and financing sources). For purposes of this Agreement, “Diamond Alternative Transaction” means any of (i) a transaction or series of transactions pursuant to which any person (or group of persons) other than Orion and its subsidiaries (including HoldCo, Orion Merger Sub and Diamond Merger Sub) (such persons (or group of persons), a “Diamond 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 outstanding shares of Diamond 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 Diamond, whether from Diamond or pursuant to a tender offer or exchange offer or otherwise, (ii) a merger, consolidation, share exchange or similar transaction pursuant to which any Diamond Third Party acquires or would acquire, directly or indirectly, assets or businesses of Diamond or any of its subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Diamond and its subsidiaries taken as a whole, (iii) any transaction pursuant to which any Diamond Third Party acquires or would acquire, directly or indirectly, control of assets (including for this purpose the outstanding equity securities of subsidiaries of Diamond and any entity surviving any merger or combination including any of them) of Diamond or any of its subsidiaries representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Diamond and its subsidiaries taken as a whole or (iv) any disposition of assets to a Diamond Third Party representing 20% or more of the revenues, net income or assets (in each case on a consolidated basis) of Diamond and its subsidiaries, taken as a whole.

(b) Except as permitted by this Section 5.3(b), neither the Board of Directors of Diamond nor any committee thereof shall (i) withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify, or fail to make, in each case in a manner adverse to Orion, the approval or recommendation by such Board of Directors or such committee of the Diamond Merger or this Agreement, (ii) approve or recommend, or propose publicly to approve or recommend, any Diamond Alternative Transaction (any action in clause (i) or this clause (ii) being referred to as a “Diamond Recommendation Change”), provided, that nothing herein shall restrict or otherwise limit Diamond from making accurate disclosure to its stockholders of factual information regarding the business, financial condition or results of operations of Diamond or, so long as Diamond provides Orion with reasonable advance notice and a copy of the proposed disclosure, the fact that a proposal the consummation of which would constitute a Diamond Alternative Transaction has been made, the identity of the party making such proposal or the material terms of such proposal (and such disclosure shall not be deemed to be a Diamond Recommendation Change), so long as the disclosure through which such factual information is conveyed, taken as a whole, is not contrary to or materially inconsistent with the

recommendation made by the Diamond Board of Directors or (iii) cause Diamond or any of its controlled affiliates to enter into any letter of intent, agreement in principle, acquisition agreement or other agreement related to any Diamond Alternative Transaction or requiring, or reasonably likely to cause, Diamond to terminate, delay or fail to consummate, or that would otherwise impede, interfere with or be inconsistent with, the consummation of the Mergers or any of the other transactions contemplated by this Agreement (other than a confidentiality agreement referred to in Section 5.3(a)). Notwithstanding the foregoing, in the event that prior to obtaining the Diamond Stockholder Approval, the Board of Directors of Diamond determines in good faith, after it has received a Diamond 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 Diamond may (subject to this and the following sentences) effect a Diamond Recommendation Change, but only at a time that is after the fourth business day following Orion’s receipt of written notice from Diamond advising Orion that the Board of Directors of Diamond has received a Diamond Superior Proposal specifying the material terms and conditions of such Diamond Superior Proposal, identifying the person making such Diamond Superior Proposal and stating that it intends to make a Diamond Recommendation Change; provided that in the event of a subsequent modification to the material terms and conditions of such Diamond Superior Proposal, the Board of Directors of Diamond may only effect a Diamond Recommendation Change after the second business day following Orion’s receipt of written notice from Diamond advising Orion of the modification to such terms and conditions; and provided further that during such four or two business day notice period, as applicable, Diamond engages (to the extent requested by Orion) in good faith negotiations with Orion to amend this Agreement in such a manner that the proposal to enter into a Diamond Alternative Transaction no longer constitutes a Diamond Superior Proposal. For purposes of this Agreement, a “Diamond Superior Proposal” means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a Diamond Third Party to enter into a Diamond Alternative Transaction (with all references to 20% in the definition of Diamond Alternative Transaction being treated as references to 50% for these purposes) that (A) did not result from a material breach of Section 5.3(a), (B) is on terms that the Board of Directors of Diamond determines in good faith (after consultation with outside counsel and a financial advisor of nationally recognized reputation) to be superior from a financial point of view to Diamond’s stockholders than the transactions contemplated by this Agreement, taking into account all relevant factors (including any changes to this Agreement that may be proposed by Orion in response to such proposal to enter into a Diamond Alternative Transaction and the identity of the person making such proposal to enter into a Diamond Alternative Transaction) and (C) is reasonably likely to be completed, taking into account all financial, regulatory, legal and other aspects of such proposal. In addition, notwithstanding anything in this Agreement to the contrary, at any time prior to the receipt of the Diamond Stockholder Approval, if the Board of Directors of Diamond 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 Diamond may effect a Diamond Recommendation Change in response to any Diamond Intervening Event, but only at a time that is after the fourth business day following Orion’s receipt of written notice from Diamond advising Orion of all material information with

respect to any such Diamond Intervening Event and stating that it intends to make a Diamond Recommendation Change and providing its rationale therefor. The term “Diamond Intervening Event” shall mean a material event or change in circumstance that arises or occurs after the date of this Agreement that, prior to the date of this Agreement, was neither known nor reasonably foreseeable by the Board of Directors of Diamond; provided, however, that (i) in no event shall the receipt, existence or terms of an Diamond Alternative Transaction or any matter relating thereto or consequence thereof constitute an Diamond Intervening Event and (ii) in no event shall any event or events that has or have an adverse effect on the business, properties, financial condition or results of operations of Orion and its subsidiaries, taken as a whole, constitute a Diamond Intervening Event unless such event or events has had or would reasonably be expected to have an Orion Material Adverse Effect.

(c) In addition to the obligations of Diamond set forth in Sections 5.3(a) and 5.3(b), Diamond shall promptly, and in any event within 24 hours of receipt thereof, advise Orion orally and in writing of any request for information or of any proposal relating to a Diamond 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. Diamond shall (i) keep Orion reasonably informed of the status and details (including amendments or proposed amendments) of any such request or proposal on a current basis and (ii) provide to Orion as soon as reasonably practicable after receipt or delivery thereof copies of all correspondence and other written materials exchanged between Diamond 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 that describes in any material respect any of the material terms or conditions of any such request or proposal.

(d) Nothing contained in this Section 5.3 shall prohibit Diamond 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 Diamond Recommendation Change shall be subject to the provisions of Section 5.3(b).

Each of Orion and Diamond 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.

(b) The parties shall jointly develop, and each of the parties shall consult and cooperate in all respects with one another, and consider in good faith the views of one another, in connection with the form and content of any analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted by or on behalf of any party, hereto in connection with proceedings under or relating to any Antitrust Law prior to their submission.

(a) From and after the Effective Time, HoldCo shall indemnify and hold harmless each individual who is as of the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of Diamond or Orion or any of their subsidiaries or who is as of the date of this Agreement, or who thereafter commences prior to the Effective Time, serving at the request of Diamond or Orion, as applicable, or any of their respective subsidiaries as a director or officer of another person (the “Indemnified Parties”), against all claims, losses, liabilities, damages, judgments, inquiries, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including with respect to matters existing or occurring at or prior to the Effective Time (including this Agreement and the transactions and actions contemplated hereby)), arising out of or pertaining to the fact that the Indemnified Party is or was an officer or director of Diamond or Orion, as applicable, or any of their respective subsidiaries or is or was serving at the request of Diamond or Orion, as applicable, or any of their respective subsidiaries as a director or officer of another person or in respect of any acts or omissions in their capacities as such directors of officers occurring prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, to the same extent as such Indemnified Parties are indemnified as of the date of this Agreement by Diamond pursuant to the Diamond Certificate of Incorporation, the By-laws of Diamond or the governing or organizational documents of any subsidiary of Diamond, or by Orion pursuant to the Orion Certificate of Incorporation, the By-laws

of Orion or the governing organizational documents of any subsidiary of Orion, as applicable, or and any indemnification agreements in existence as of the date of this Agreement. In the event of any such claim, action, suit or proceeding, (i) each Indemnified Party will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit or proceeding from HoldCo to the same extent as such Indemnified Parties are entitled to advance of expenses as of the date of this Agreement by Diamond pursuant to the Diamond Certificate of Incorporation, the By-laws of Diamond or the governing or organizational documents of any subsidiary of Diamond, or by Orion pursuant to the Orion Certificate of Incorporation, the By-laws of Orion or the governing or organizational documents of any subsidiary of Orion, as applicable, and any indemnification agreements in existence as of the date of this Agreement; provided that any person to whom expenses are advanced provides an undertaking, if and only to the extent required by the DGCL, the Diamond Certificate of Incorporation or the By-laws of Diamond, or the Orion Certificate of Incorporation or the By-laws of Orion, as applicable, and any indemnification agreements in existence as of the date of this Agreement, to repay such advances if it is ultimately determined that such person is not entitled to indemnification and (ii) HoldCo shall, and shall cause its subsidiaries to, cooperate in the defense of any such matter. In the event that HoldCo, Orion Surviving Corporation or Diamond Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, HoldCo, Orion Surviving Corporation and/or Diamond Surviving Corporation, as applicable, shall cause proper provision to be made so that the successors and assigns of HoldCo, Orion Surviving Corporation and/or Diamond Surviving Corporation, as applicable, assume the obligations set forth in this Section 6.4.

annual premium equal to the Orion Maximum Amount, in respect of each policy year within such period; provided that in lieu of the foregoing, Orion may obtain at or prior to the Effective Time a six-year “tail” policy under Orion’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that, on an annual basis, does not exceed the Orion Maximum Amount.

(c) The provisions of this Section 6.4 (i) shall survive consummation of the Mergers, (ii) are intended to be for the benefit of, and will be enforceable by, each indemnified or insured party (including the Indemnified Parties), his or her heirs and his or her representatives, and (iii) are in addition to, and not in substitution for, any other rights to indemnification or contribution that any such person may have by contract or otherwise.

Each of Orion, Diamond and their respective subsidiaries shall use reasonable best efforts to cause (a) each of the Orion Merger and the Diamond Merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code or, alternatively, as a transaction qualifying for nonrecognition of gain and loss under Section 351 of the Code and (b) the delivery of the opinions of counsel referred to in Sections 7.2(d) and 7.3(d). The parties shall report each of the Mergers in a manner consistent with such qualification.

In addition, and without limiting the generality of the foregoing, and subject to any Applicable Law and obligations under applicable Orion Labor Agreements or Diamond Labor Agreements: (i) each Employee shall be immediately eligible to participate, without any waiting time, in any and all New Plans which are welfare benefit plans to the extent coverage under such New Plan replaces coverage under a comparable Orion Benefit Plan or Diamond Benefit Plan, as applicable, in which such Employee participated immediately before the Effective Time (such plans, collectively, the “Old Plans”); and (ii) for purposes of each New Plan providing medical, dental, pharmaceutical and/or vision benefits to any Employee, HoldCo shall cause all pre-existing condition exclusions and actively-at-work requirements of such New Plan to be waived for such Employee and his or her covered dependents, and HoldCo shall cause any eligible expenses incurred by such Employee and his or her covered dependents during the portion of the plan year of the Old Plan ending on the date such Employee’s participation in the corresponding New Plan begins to be taken into account under such New Plan for purposes of satisfying all deductible, coinsurance and maximum out-of-pocket requirements applicable to such Employee and his or her covered dependents for the applicable plan year as if such amounts had been paid in accordance with such New Plan.

(b) Notwithstanding anything to the contrary in this Agreement, from and after the Effective Time, HoldCo shall honor or cause to be honored, in accordance with their terms, each of the Orion Labor Agreements and Diamond Labor Agreements. Prior to the Effective Time, Orion shall comply with any obligations it has under Applicable Laws and the Orion Labor Agreements, and Diamond shall comply with any obligations it has under Applicable Laws and the Diamond Labor Agreements, to inform and/or consult with any labor union, labor organization, works council or any other employee representative body in connection with this Agreement, the arrangements proposed in this Agreement and/or the Closing. Each of Orion and Diamond agree to reasonably cooperate with each other in order to comply with such obligations.

(c) Nothing contained in this Section 6.11 shall (i) be construed to establish, amend, or modify any benefit or compensation plan, program, agreement, contract, policy or arrangement, (ii) limit the ability of HoldCo, Orion or Diamond or any of their subsidiaries or affiliates to amend, modify or terminate any benefit or compensation plan, program, agreement, contract, policy or arrangement at any time assumed, established, sponsored or maintained by any of them, (iii) create any third-party beneficiary rights or obligations in any person (including any Employee) other than the parties to this Agreement or any right to employment or continued employment or to a particular term or condition of employment with HoldCo, Orion or Diamond or any of their subsidiaries, or any of their respective affiliates, or (iv) limit the right of HoldCo, Orion or Diamond (or any of their subsidiaries) to terminate the employment or service of any employee or other service provider following the Closing Date at any time and for any or no reason.

Section 6.12 Section 16(b). HoldCo, Orion and Diamond shall each take all such steps as are reasonably necessary to cause the transactions contemplated by this Agreement and any other dispositions of equity securities of Orion or Diamond (including derivative securities) or acquisitions of equity securities of HoldCo (including derivative securities) in connection herewith by any individual who (a) is a director or officer of Orion or Diamond or (b) at the Effective Time, will become a director or officer of HoldCo, in each case to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 6.13 Dividend Coordination. Orion and Diamond shall coordinate with each other to designate the same record and payment dates for any quarterly dividends or distributions declared in accordance with this Agreement in any calendar quarter in which the Closing Date might reasonably be expected to occur.

Section 6.14 Certain Litigation. Each party shall promptly advise the other party of any litigation commenced after the date hereof against such party or any of its directors (in their capacity as such) by any stockholders of such party (on their own behalf or on behalf of such party) relating to this Agreement or the transactions contemplated hereby, and shall keep the other party reasonably informed regarding any such litigation. Such party shall give the other party the opportunity to participate in the defense or settlement of any such stockholder litigation, and no such settlement shall be agreed to without the other party’s prior consent (which consent shall not be unreasonably withheld, conditioned or delayed).

Section 6.15 HoldCo and Merger Sub Approvals. Promptly following the execution of this Agreement, Diamond and Orion shall cause HoldCo to take all action necessary to cause this Agreement and the transactions contemplated by this Agreement, including the Mergers, to be adopted by HoldCo as the sole stockholders of each of Orion Merger Sub and Diamond Merger Sub, as applicable, for all required purposes under Applicable Law.

Section 9.9 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 to enforce specifically the performance of terms and provisions of this Agreement in any court referred to in clause 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. 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 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; (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, if (and only if) such court finds it lacks subject matter jurisdiction, the Federal court of the United States of America sitting in Delaware, and appellate courts thereof.

Section 9.12 Severability. If any term or other provision of this Agreement is 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 so long as either the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party or such party waives its rights under this Section 9.12 with respect thereto. Upon a determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto 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 an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized representatives as of the date first above written.
