(iii)                               Each Orion PSU Award, whether vested or unvested, that is outstanding immediately prior to the Effective Time shall, as of the Effective Time, automatically and without any action on the part of the holder thereof, be converted into a HoldCo restricted stock unit award on the terms and conditions (including, if applicable, any continuing vesting requirements) under the applicable plan and award agreement in effect immediately prior to the Effective Time, with respect to a number of shares of HoldCo Common Stock, rounded up to the nearest whole share, determined by multiplying the number (A) of shares of Orion Common Stock subject to such Orion PSU Award immediately prior to the Effective Time by (B) the Orion Exchange Ratio, provided that, each unvested Orion PSU outstanding immediately prior to the Effective Time shall be converted into HoldCo restricted stock units vesting at the same times as the expiration of the applicable performance periods under the Orion PSU awards, with respect to a number of shares of HoldCo Common Stock, rounded up to the nearest whole share, determined based on the greater of (i) the applicable target level or (ii) the actual level of performance as of the Effective Time, in each case, under the terms of the Orion PSU awards and multiplied by the Orion Exchange Ratio.

(iv)                              At the Effective Time, each right of any kind, contingent or accrued, to acquire or receive shares of Orion Common Stock or benefits measured by the value of shares of Orion Common Stock, and each award of any kind consisting of shares of Orion Common Stock that may be held, awarded, outstanding, payable or reserved for issuance under the Orion Equity Plans and any other Orion Benefit Plan, other than the Orion Options, the Orion RSU Awards and the Orion PSU Awards (the “Orion Awards”) shall be converted into the right to acquire or receive, as the case may be, the number of shares of HoldCo Common Stock equal to the product (rounded down to the nearest whole number) determined by multiplying (i) the total number of shares of Orion Common Stock subject to such Orion Award immediately prior to the Effective

12

Time by (ii) the Orion Exchange Ratio, and such Orion Awards shall otherwise be subject to the terms and conditions applicable to the rights under the relevant Orion Equity Plan or other Orion Benefit Plan.  Similarly, all Orion Equity Plans and other Orion Benefit Plan (and awards thereunder) providing for cash payments measured by the value of shares of Orion Common Stock shall be deemed to refer to the number of shares of HoldCo Common Stock equal to the product determined by multiplying such shares of Orion Common Stock by the Orion Exchange Ratio, and such cash payments shall otherwise be made on the terms and conditions applicable under the relevant Orion Equity Plan or other Orion Benefit Plan.

(v)                                 Effective as of the Effective Time, HoldCo shall assume (A) the Orion Equity Awards in accordance with the terms of this Section 3.1(g) and (B) sponsorship of each Orion Equity Plan, provided that references to Orion therein shall thereupon be deemed references to HoldCo and references to Orion Common Stock therein shall be deemed references to HoldCo Common Stock with appropriate equitable adjustments to reflect the transactions contemplated by this Agreement.

(vi)                              Prior to the Effective Time, the Board of Directors of Orion or the appropriate committee thereof shall adopt resolutions providing for the treatment of the Orion Options, Orion RSU Awards, Orion PSU Awards and Orion Awards (collectively, the “Orion Equity Awards”) and the Orion Equity Plans as contemplated by this Section 3.1(g).

(vii)                           As soon as practicable after the Effective Time, HoldCo shall prepare and file with the SEC a Form S-8 (or file such other appropriate form) registering a number of shares of HoldCo Common Stock necessary to fulfill HoldCo’s obligations under this Section 3.1(g).  HoldCo shall take all corporate action necessary to reserve for issuance a sufficient number of shares of HoldCo Common Stock for delivery with respect to the Orion Equity Awards assumed by it in accordance with this Section 3.1(g).

(h)                                 No Dissenters’ Rights. In accordance with Section 262 of the DGCL, no appraisal rights shall be available to holders of Diamond Common Stock or Orion Common Stock in connection with the Mergers.

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

13

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,

14

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-

15

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.

16

(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.

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

60

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,

61

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

62

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

63

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)

64

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

65

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).

(b)                                 Orion shall, as promptly as practicable after the Form S-4 is declared effective under the Securities Act, duly give notice of, convene and hold a meeting of its stockholders (the “Orion Stockholders Meeting”) in accordance with the DGCL for the purpose

67

of obtaining the Orion Stockholder Approval and shall, subject to the provisions of Section 5.2(b), through its Board of Directors, recommend to its stockholders the adoption of this Agreement.  Orion may only postpone or adjourn the Orion Stockholder’s Meeting (i) to solicit additional proxies for the purpose of obtaining the Orion Stockholder Approval, (ii) for the absence of a quorum, and (iii) to allow reasonable additional time for the filing and/or mailing of any supplemental or amended disclosure that Orion has determined after consultation with outside legal counsel is reasonably likely to be required under Applicable Law and for such supplemental or amended disclosure to be disseminated and reviewed by stockholders of Orion prior to the Orion Stockholders Meeting; provided, however, that Orion shall postpone or adjourn the Orion Stockholders Meeting up to two (2) times for up to thirty days each time upon the reasonable request of Diamond.

68

such other party may reasonably request; provided, however, that the foregoing shall not require Orion or Diamond to disclose any information pursuant to this Section 6.2 to the extent that (i) in the reasonable good faith judgment of such party, any Applicable Law requires such party or its Subsidiaries to restrict or prohibit access to any such information, (ii) in the reasonable good faith judgment of such party, the information is subject to confidentiality obligations to a third party or (iii) disclosure of any such information or document would result in the loss of attorney-client privilege; provided, further, that with respect to clauses (i) through (iii) of this Section 6.2, 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 (i) through (iii), utilize the procedures of a joint defense agreement or implement such other techniques if the parties determine that doing so would reasonably permit the disclosure of such information without violating Applicable Law or jeopardizing such privilege.  No review pursuant to this Section 6.2 shall affect any representation or warranty given by the other party hereto.  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.  Each of the parties shall (i) promptly notify the other party of any communication inquiry or investigation received by that party from, or given by it to, any Governmental Entity and, subject to Applicable Law, permit the other party to review in advance any proposed communication to any such Governmental Entity and incorporate the other party’s reasonable comments, (ii) not agree to participate in any meeting or discussion with any such Governmental Entity in respect of any filing, investigation or inquiry concerning this Agreement or the Mergers unless, to the extent reasonably practicable, it consults with the other party in advance and, to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate therein and (iii) promptly furnish the other party with copies of all correspondence, filings and written communications between them and their affiliates and their respective officers, directors, employees and Representatives, on one hand, and any such Governmental Entity or its respective staff on the other hand, with respect to this Agreement and the Merger in order for such other party to meaningfully consult and participate in accordance with the preceding clauses (i) and (ii), provided that materials furnished pursuant to this Section 6.3(b) may be redacted as necessary to address reasonable attorney-client or other privilege or confidentiality concerns.

70

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.

(b)                                 For a period of six years from and after the Effective Time, HoldCo shall either cause to be maintained in effect the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by Diamond or Orion or any of their subsidiaries or provide substitute polices for of not less than the existing coverage and have other terms not less favorable to the insured persons with respect to claims arising from facts or events that occurred on or before the Effective Time, except that in no event shall HoldCo be required to pay with respect to such insurance policies (or substitute insurance policies) (i) of Diamond in respect of any one policy year more than 300% of the annual premium payable by Diamond for such insurance for the prior twelve months (the “Diamond Maximum Amount”), and if HoldCo is unable to obtain the insurance required by this Section 6.4 it shall obtain as much comparable insurance as possible for the years within such six-year period for an annual premium equal to the Diamond Maximum Amount, in respect of each policy year within such period; provided that
