The directors of Surviving Company immediately prior to the Second Merger Effective Time shall, from and after the Second Merger Effective Time, be the managers of the Surviving Company until their successors shall have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the Surviving Company’s certificate of formation and Limited Liability Company Agreement.

Section 1.6 Effect on Capital Stock.

(a) At the Effective Time by virtue of the Merger and without any action on the part of any party or holder of any of their securities, subject to the other provisions of this Article 1 and Section 2.1, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (excluding any Excluded Shares and any Dissenting Shares) shall, by virtue of this Agreement and without any action on the part of the holder thereof, be converted into and exchangeable for the right to receive the following consideration (the “Merger Consideration”): the combination of (x) $20.00 (the “Per Share Cash Consideration”) and (y) 1.932 shares of validly issued, fully paid and non-assessable shares of Parent Common Stock (the “Per Share Stock Consideration” or the “Exchange Ratio”), subject to adjustment in accordance with Section 1.6(c).

(b) All of the shares of Company Common Stock converted into the Merger Consideration pursuant to this Article 1 shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate (each, a “Certificate”) previously representing any such shares of Company Common Stock or non-certificated shares represented by book entry (“Book Entry Shares”) shall thereafter cease to have any rights with respect to such securities, except the right to receive (i) the Merger Consideration, (ii) any dividends and other distributions in accordance with Section 2.1(c), and (iii) any cash to be paid in lieu of any fractional share of Parent Common Stock in accordance with Section 2.1(e). Each Dissenting Share, whether represented by a certificate or book-entry, shall thereafter represent only the right to receive the payments described in Section 1.8.

(c) If, between the date of this Agreement and the Effective Time, the shares of Parent Common Stock or Company Common Stock shall be changed or proposed to be changed into a different number or class of shares by reason of the occurrence of or record date with respect to any reclassification, recapitalization, split-up, combination, exchange of shares or similar readjustment, in any such case within such period, or a stock dividend thereon shall be declared with a record date within such period, appropriate adjustments shall be made to the Per Share Stock Consideration.

(d) At the Effective Time, all shares of Company Common Stock that are owned directly or indirectly by Parent, Merger Sub, Second Merger Sub or the Company or any of their respective Subsidiaries shall be cancelled and shall cease to exist and no stock of Parent, cash or other consideration shall be delivered in exchange therefore (all such shares, the “Excluded Shares”). All shares of Parent Common Stock that are owned by the Company or any of its Subsidiaries shall become authorized unissued stock of Parent.

(e) At the Effective Time, by virtue of the Merger and without any action on the part of any holder thereof, the shares of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall, in the aggregate, be converted into and become 26,000,000 validly issued, fully paid and nonassessable shares of common stock of the Surviving Company.

(f) At the Second Merger Effective Time, by virtue of the Second Merger and without any action on the part of any holder thereof, (i) each share of common stock, par value

$0.0001 per share, of the Company, as the Surviving Company, issued and outstanding immediately prior to the Second Merger Effective Time shall be converted into and become one validly issued, fully paid and nonassessable limited liability company interest of Second Merger Sub, as the new Surviving Company, and shall constitute the only outstanding limited liability company interests of the Surviving Company, and (ii) each limited liability company interest of Second Merger Sub issued and outstanding immediately prior to the Second Merger Effective Time shall be canceled.

Section 1.7 Stock Options, Warrants and Restricted Stock Units.

(a) Each option granted by the Company to purchase shares of Company Common Stock (each, a “Company Option”) that was granted pursuant to any stock option, purchase or award plan, program or arrangement of the Company (collectively, the “Company Stock Plans”), that is outstanding and unexercised immediately prior to the Effective Time, and that is not then vested and exercisable, shall become fully vested and exercisable on an accelerated basis immediately prior to the Effective Time. Immediately before the Effective Time, each Company Option that is then outstanding and unexercised shall be exercised (pursuant to an irrevocable written exercise notice from the holder of the Company Option that is contingent only on the Closing, the form of which shall be subject to approval by Parent and shall be delivered by Company to Parent within 15 Business Days following the execution and delivery of this Agreement) in accordance with the Company Stock Plans, including on a “net cashless” basis. The Company and Parent shall agree on the terms, conditions and manner of exercise of the Company Options and the terms, conditions and manner of the assumption of the Company Options, including, to the extent applicable, acceptable methods of payment of the option exercise price and applicable withholding taxes and determination of taxable income. As of the Effective Time, each share of Company Common Stock issued with respect to such former Company Option shall be converted into the right to receive the Merger Consideration pursuant to Section 1.6. At the Effective Time, each Company Option that is outstanding and unexercised immediately prior to the Effective Time and for which such a written exercise notice is not delivered to Parent within 15 Business Days following the execution and delivery of this Agreement shall be assumed by Parent and converted into an option to acquire shares of Parent Common Stock, and, with respect to any such Company Option that is intended to be an “incentive stock option” under Section 422 of the Code, the option exercise price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in accordance with Sections 422 and 424 of the Code and with respect to any such Company Option that is not intended to be an “incentive stock option,” the option exercise price, the number of shares purchasable pursuant to such option and the terms and conditions of exercise of such option shall be determined in accordance with Section 409A of the Code.

(b) At the Effective Time, each warrant to purchase Company Common Stock (each, a “Company Warrant”) that is outstanding and unexercised immediately prior to the Effective Time, whether vested or unvested, shall, in connection with the Merger, be assumed by Parent and be converted into a warrant (an “Assumed Warrant”) to acquire Parent Common Stock (the “Share Portion”) and cash (the “Cash Portion”) in accordance with this Section 1.7(b). As of the Effective Time each Assumed Warrant shall continue to have, and be subject to, the same terms and conditions of the applicable agreement evidencing such Company Warrant, as so assumed and converted, immediately prior to the Effective Time (including without limitation vesting schedules and vesting commencement dates), except that:

(i) the Share Portion of each Assumed Warrant shall (subject to the vesting provisions thereof) be exercisable (A) for that number of whole shares of Parent Common Stock equal to the product obtained by multiplying the number of shares of Company Common Stock that were issuable upon exercise of such assumed and converted Company Warrant immediately prior to the Effective Time by the Per Share Stock Consideration, and rounded up to the nearest whole share and (B) for an exercise price per share of Parent Common Stock equal to (1) the quotient obtained by dividing the exercise price per share of Company Common Stock at which such assumed and converted Company Warrant was exercisable immediately prior to the Effective Time by the Per Share Stock Consideration, multiplied by (2) 0.5, and rounding up to the nearest whole cent;

(ii) the Cash Portion of each Assumed Warrant shall (subject to the vesting provisions of the Assumed Warrant) be exercisable (A) for that amount of cash equal to the product obtained by multiplying the number of shares of Company Common Stock that were issuable upon exercise of such assumed and converted Company Warrant immediately prior to the Effective Time by the Per Share Cash Consideration, and rounded up to the nearest whole cent and (B) for an exercise price per dollar of the Cash Portion equal to (1) the product obtained by multiplying the exercise price per share of Company Common Stock at which such amended and converted Company Warrant was exercisable immediately prior to the Effective Time by 0.5, divided by (2) the Per Share Cash Consideration, and rounded up to the nearest whole cent;

(iii) neither the Cash Portion nor the Share Portion of each unexpired and unexercised Assumed Warrant shall be exercisable independent of the other and the Assumed Warrant shall provide that (A) with respect to the purchase of each share of Parent Common Stock upon exercise of the Share Portion of an Assumed Warrant, such purchase shall be conditioned upon the holder thereof simultaneously exercising (and, accordingly, paying the applicable exercise price) a portion of the Cash Portion of the Assumed Warrant that is equal to the quotient obtained by dividing the Per Share Stock Consideration by the Per Share Cash Consideration (provided that the aggregate amount of cash to be obtained in connection with each such exercise shall be rounded up to the nearest whole cent) and (B), with respect to the exercise of an Assumed Warrant for each dollar of the Cash Portion, such exercise shall be conditioned upon the holder thereof simultaneously exercising the Assumed Warrant to purchase an amount of shares of the Share Portion equal to the quotient obtained by dividing the Per Share Stock Consideration by the Per Share Cash Consideration (provided that the aggregate amount of shares to be obtained in connection with each such exercise shall be rounded down to the nearest whole share); and

(iv) in no event shall the Assumed Warrants be exercised for partial shares of Parent Common Stock.

Issuances of Parent Common Stock and payments of cash upon exercise of Assumed Warrants shall be subject to applicable withholding. Any provision of this Agreement to the contrary notwithstanding, other than to the extent that the Company is contractually obligated to accelerate the vesting of any Company Warrant, no Company Warrant shall have accelerated vesting by virtue of the transactions contemplated under this Agreement (whether alone or in conjunction with any other event). Following the Effective Time, no holder of a Company Warrant shall have any right to receive any shares of Company Common Stock in respect of such Company Warrant.

(c) At the Effective Time, each restricted stock unit (each, a “Restricted Stock Unit” or “RSU”) which was issued pursuant to any Company Stock Plans and outstanding immediately prior to the Effective Time, and that has not then vested and been settled, shall vest and be settled by the Company through the issuance to each holder thereof of one share of Company Common Stock in respect of each such Restricted Stock Unit (subject to any applicable withholding). As of the Effective Time, each share of Company Common Stock issued with respect to such former Restricted Stock Unit shall be converted into the right to receive the Merger Consideration pursuant to Section 1.6.

(d) The Company (or its Board of Directors or the appropriate committee thereof, or the President of the Company, if applicable) shall (i) make any amendments to the terms of the Company Stock Plans, take all corporate action necessary for the adjustment of Company Options, Company Warrants and Restricted Stock Units, and take any other actions necessary or appropriate to give effect to the transactions contemplated by this Section 1.7, including, without limitation, obtaining any required consents or contingent written notice of exercise of Company Options from the holders of any Company Options, Company Warrants and Restricted Stock Units, and (ii) shall take all reasonable actions necessary to ensure that from and after the Effective Time, (x) Parent will not be required to deliver any shares of the capital stock of the Company or any of its Subsidiaries to any Person pursuant to or in settlement of Company Options, Company Warrants or Restricted Stock Units after the Effective Time, and (y) other than as set forth in this Section 1.7, Parent will not be bound by any options, warrants, rights, awards or other arrangements that would entitle any Person, other than Parent, to beneficially own shares of Parent or receive any payments in respect of such options, warrants, rights, awards or arrangements.

(e) Not later than three (3) business days after the Effective Time, Parent shall prepare and file with the SEC (i) a registration statement on Form S-3 (or other appropriate form) registering the resale of all the shares of Parent Common Stock subject to the Assumed Warrants, and such registration statement shall be kept effective (and the current status of the prospectus or prospectuses required thereby shall be maintained), as long as required pursuant to the terms of the Registration Rights Agreement. Prior to the Effective Time, Parent shall take such actions necessary to effectuate the transactions contemplated by this Section 1.7, including reservation of sufficient shares of Parent Common Stock to satisfy the obligations under the Assumed Warrants.

Section 1.8 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, with respect to each share of Company Common Stock as to which the holder thereof shall have properly complied with the provisions of Article 113 of the CBCA as to appraisal

rights (each, a “Dissenting Share”), if any, such share will not be converted into, or represent the right to receive, the Merger Consideration. Such holder shall be entitled to payment, solely from the Surviving Company, of the appraisal value of the Dissenting Shares to the extent permitted by and in accordance with the provisions of Article 113 of the CBCA; provided, however, that (i) if any holder of Dissenting Shares, under the circumstances permitted by and in accordance with the CBCA, affirmatively withdraws or waives such holder’s demand for appraisal of such Dissenting Shares or loses his or her right to appraisal and payment for his or her shares of Company Common Stock under Article 113 of the CBCA, (ii) if any holder of Dissenting Shares fails to perfect or establish such holder’s entitlement to appraisal rights as provided in the CBCA, (iii) if a court of competent jurisdiction determines that any holder of Dissenting Shares is not entitled to the relief provided in Article 113 of the CBCA, or (iv) if any holder of Dissenting Shares takes or fails to take any action the consequence of which is that such holder is not entitled to payment for his or her shares under the CBCA, such holder or holders (as the case may be) shall forfeit the right to appraisal of such shares of Company Common Stock, and such shares of Company Common Stock shall thereupon cease to constitute Dissenting Shares, and each such share of Company Common Stock shall thereafter be deemed to have been converted into and to have become, as of the Effective Time, the right to receive, without interest thereon, the Merger Consideration. The Company shall give Parent prompt notice of any demands received by the Company for appraisals of shares of Company Common Stock, and Parent shall have the right to participate in all negotiations and proceedings with respect to such demands. The Company shall not settle, make any payments with respect to, or offer to settle, any claim with respect to Dissenting Shares without the written consent of Parent.

ARTICLE 2

EXCHANGE OF CERTIFICATES

Section 2.1 Exchange of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Parent shall deposit, or shall cause to be deposited, with a bank or trust company designated by Parent and reasonably satisfactory to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Article 2, through the Exchange Agent, sufficient cash and certificates representing shares of Parent Common Stock to make pursuant to this Article 2 all deliveries of cash and Parent Common Stock as are required by Article 1. Parent agrees to make available to the Exchange Agent, from time to time as needed, cash sufficient to pay any dividends and other distributions pursuant to Section 2.1(c) and to make payments in lieu of fractional shares pursuant to Section 2.1(e). The Exchange Agent shall, pursuant to irrevocable instructions, deliver the Merger Consideration contemplated to be paid for shares of Company Common Stock pursuant to this Agreement out of the Exchange Fund. Except as contemplated by Sections 2.1(c) and 2.1(e), the Exchange Fund shall not be used for any other purpose. Any cash and certificates representing Parent Common Stock deposited with the Exchange Agent (including as payment for fractional shares in accordance with Section 2.1(e) and any dividends or other distributions in accordance with Section 2.1(c)) shall hereinafter be referred to as the “Exchange Fund.”

(b) Exchange Procedures. Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of a Certificate or Certificates or Book Entry Shares that immediately prior to the Effective Time represented outstanding shares of Company Common Stock (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 proper delivery of the Certificates to the Exchange Agent or receipt by the Exchange Agent of an “agent’s message” with respect to Book Entry Shares, and shall be in customary form and subject to the reasonable approval of the Company prior to the Effective Time) and (ii) instructions for use in effecting the surrender of the Certificates or Book Entry Shares in exchange for the Merger Consideration payable in respect of the shares of Company Common Stock represented thereby. Upon surrender of Certificates or Book Entry Shares for cancellation to the Exchange Agent together with such letter of transmittal, properly completed and duly executed, and such other documents as may be required pursuant to such instructions, the holder of such Certificates or Book Entry Shares shall be entitled to receive in exchange therefor (A) one or more shares of Parent Common Stock (which shall be in uncertificated book-entry form) representing, in the aggregate, the whole number of shares of Parent Common Stock, if any, that such holder has the right to receive pursuant to Section 1.6 (after taking into account all shares of Company Common Stock previously represented by all Certificates then held by such holder) and (B) a check in the amount equal to the cash portion of the Merger Consideration that such holder has the right to receive pursuant to Section 1.6 and this Article 2, including cash payable in lieu of any fractional shares of Parent Common Stock pursuant to Section 2.1(e) and dividends and other distributions pursuant to Section 2.1(c). No interest shall be paid or accrued on any Merger Consideration, cash in lieu of fractional shares or on any unpaid dividends and distributions payable to holders of Certificates or Book Entry Shares. In the event of a transfer of ownership of shares of Company Common Stock that is not registered in the transfer records of the Company, the Merger Consideration payable in respect of such shares of Company Common Stock may be paid to a transferee if the Certificate representing such shares of Company Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other Taxes required by reason of the delivery of the Merger Consideration in any name other than that of the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable. Until surrendered as contemplated by this Section 2.1, each Certificate and Book Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the Merger Consideration payable in respect of the shares of Company Common Stock represented thereby, cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 2.1(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.1(c).

(c) Distributions with Respect to Unexchanged Shares of Parent Common Stock. No dividends or other distributions declared or made with respect to shares of Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate or Book Entry Shares with respect to the shares of Parent Common Stock that such holder would be entitled to receive upon surrender thereof and no cash payment in lieu of fractional shares of Parent Common Stock shall be paid to any such holder until such holder shall surrender such Certificate or Book Entry Shares in accordance with this Section 2.1. Subject to

applicable Law, following surrender of any such Certificate, there shall be paid to such holder of shares of Parent Common Stock issuable in exchange therefor, without interest, (a) promptly after the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such holder’s whole shares of Parent Common Stock, and (b) 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 holder’s whole shares of Parent Common Stock. For purposes of dividends or other distributions in respect of shares of Parent Common Stock.

(d) Further Rights in Company Common Stock. The Merger Consideration issued upon conversion of a share of Company Common Stock in accordance with the terms hereof (including any payments made pursuant to Section 2.1(c) or Section 2.1(e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such share of Company Common Stock.

(e) Fractional Shares. No certificates or scrip or shares of Parent Common Stock representing fractional shares of Parent Common Stock or book-entry credit of the same shall be issued upon the surrender for exchange of Certificates or Book Entry Shares, no dividend or other distribution, stock split or interest shall relate to any such fractional share, and such fractional share interests will not entitle the owner thereof to vote or to have any rights as a holder of any shares of Parent Common Stock.

Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all Certificates or Book Entry Shares delivered by such holder) shall receive, in lieu thereof, cash (without interest) in an amount, rounded to the nearest whole cent, equal to the product of (i) the average of the closing sale prices per share of Parent Common Stock on the NYSE as reported by The Wall Street Journal for the five trading days immediately preceding the Closing Date and (ii) the fraction of a share of Parent Common Stock that such holder would otherwise be entitled to receive pursuant to Section 1.6. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent shall so notify Parent, and Parent shall deposit such amount with the Exchange Agent and shall cause the Exchange Agent to forward payments to such holders of fractional interests subject to and in accordance with the terms hereof. The parties acknowledge that payment of cash consideration in lieu of issuing fractional shares of Parent Common Stock was not separately bargained for consideration but merely represents a mechanical rounding off for purposes of simplifying the corporate and accounting problems that would otherwise be caused by the issuance of fractional shares of Parent Common Stock.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund that remains undistributed to the holders of Company Common Stock for nine months after the Effective Time shall be delivered to Parent upon demand and, from and after such delivery to Parent, any holders of Company Common Stock who have not theretofore complied with this Article 2 shall thereafter look only to Parent, as a general creditor thereof, for the Merger Consideration payable in respect of such shares of Company Common Stock, any cash in lieu of

fractional shares of Parent Common Stock to which they are entitled pursuant to Section 2.1(e) and any dividends or other distributions with respect to Parent Common Stock to which they are entitled pursuant to Section 2.1(c), in each case, without any interest thereon.

(g) No Liability. Neither Parent nor the Surviving Company shall be liable to any holder of shares of Company Common Stock for any such shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(h) 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 in form and substance acceptable to Parent and, if required by Parent, the posting by such Person of a bond, in such reasonable amount as Parent may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent shall pay in exchange for such lost, stolen or destroyed Certificate the Merger Consideration payable in respect of the shares of Company Common Stock represented by such Certificate, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.1(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.1(c), in each case, without any interest thereon.

(i) Withholding. Each of Parent, the Surviving Company and the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as Parent, the Surviving Company or the Exchange Agent is required to deduct and withhold under the Code or any provision of state, local, or foreign Tax Law, with respect to the making of such payment. To the extent that amounts are so withheld by Parent, the Surviving Company or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of Company Common Stock in respect of whom such deduction and withholding was made by Parent, the Surviving Company or the Exchange Agent, as the case may be.

(j) Investment of Cash by the Exchange Agent; Return of Certain Funds. The Exchange Agent shall invest any cash included in the Exchange Fund as directed by Parent on a daily basis; provided, that no such investment or loss thereon shall affect the amounts payable or the timing of the amounts payable to Company stockholders pursuant to the other provisions of this Article 2. Any interest and other income resulting from such investments shall promptly be paid to Parent. Any portion of the Merger Consideration deposited with the Exchange Agent pursuant to this Section 2.1 to pay for shares of Company Common Stock for which appraisal rights shall have been perfected shall be returned to Parent upon demand. The Exchange Fund shall be invested by the Exchange Agent as directed by Parent, provided that such investments shall be in money market funds rated AAA by Standard & Poor’s Corporation or deposit accounts provided by commercial banks rated A+ or better by Standard & Poor’s Corporation.

Section 2.2 Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock theretofore outstanding on the records of the Company. From and after the Effective Time, any Certificates or Book Entry Shares presented to the

Exchange Agent or Parent for any reason shall be converted into the Merger Consideration payable in respect of the shares of Company Common Stock previously represented thereby, any cash in lieu of fractional shares of Parent Common Stock to which the holders thereof are entitled pursuant to Section 2.1(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.1(c), in each case without any interest thereon.

Section 2.3 Further Assurances. At and after the Effective Time, the officers, directors and managers of the Surviving Company shall be authorized to execute and deliver, in the name and on behalf of Merger Sub, Second Merger Sub or the Company, any deeds, bills of sale, assignments or assurances and to take and do, in the name and on behalf of Merger Sub, Second Merger Sub or the Company, any other actions and things necessary to vest, perfect or confirm of record or otherwise in the Surviving Company any and all right, title and interest in, to and under any of the rights, properties or assets acquired or to be acquired by Merger Sub and Second Merger Sub as a result of, or in connection with, the Merger and the Second Merger.

Except for changes in Laws (or interpretations thereof) or changes generally affecting the oil and gas exploration, development and production industry (including changes in commodity prices) and normal depletion by production, there has been no change in respect of the matters addressed in the Parent Reserve Report that, individually or in the aggregate, would have a Material Adverse Effect on Parent.

Notwithstanding the foregoing, at any time prior to obtaining the Company Required Vote, and subject to the Company’s compliance at all times with the provisions of this Section 5.3 and Section 5.6, the Company Board may make a Company Adverse Recommendation Change if in response to an unsolicited Acquisition Proposal, (1) the Company Board concludes in good faith that such Acquisition Proposal constitutes a Superior Proposal and, after consultation with the Company’s outside counsel and financial advisors, that a Company Adverse Recommendation Change is necessary in order to comply with its fiduciary duties under applicable Law, and (2) the Company Board has approved or concurrently approves a definitive agreement in respect of such Superior Proposal and terminates this Agreement pursuant to Section 7.1(d) and otherwise complies with Section 7.1(d), Section 8.1 and the other provisions of this Agreement; provided, however, that the Company shall not be entitled to exercise its right to make a Company Adverse Recommendation Change in response to a Superior Proposal or execute or enter into an Acquisition Agreement for a Superior Proposal (x) until four Business Days after the Company provides written notice to Parent (a “Company Notice”) advising Parent that the Company Board or a committee thereof has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal, and identifying the Person or group making such Superior Proposal and, at the request of Parent, the Company shall negotiate in good faith with Parent during such four Business Day period, with respect to any alternative transaction (including any modifications to the terms of this Agreement) that would allow the Company Board not to make such Company Adverse Recommendation Change consistent with its fiduciary duties (it being understood that any change in the financial or other material terms of a Superior Proposal shall require a new Company Notice and a new four Business Day period under this Section 5.3(b)).

(c) As promptly as practicable, and in any event within 24 hours after receipt thereof, the Company shall advise Parent in writing of any Acquisition Proposal received from any Person, or any request for information, inquiry, discussions or negotiations with respect to any Acquisition Proposal or contemplated Acquisition Proposal, and the terms and conditions of such request, Acquisition Proposal, inquiry, discussions or negotiations, and the Company shall promptly (and in any event within 24 hours) provide to Parent copies of any written materials received by the Company in connection with any of the foregoing, and the identity of the Person or group making any such request, Acquisition Proposal or inquiry or with whom any discussions or negotiations are taking place. The Company agrees that it shall simultaneously provide to Parent any non-public information concerning itself or its Subsidiaries provided to

any other Person or group in connection with any Acquisition Proposal which was not previously provided to Parent. The Company shall keep Parent fully and promptly informed (and in any event within 24 hours after any change therein) of the status of any Acquisition Proposals (including the identity of the parties and price involved and any changes to any financial or other material terms and conditions thereof). Without limiting the foregoing, the Company shall promptly (and in any event within 24 hours) notify Parent in writing if it determines to engage in any actions described in clause (ii) of Section 5.3(a) and shall keep Parent reasonably informed in writing on a prompt basis (and in any event within 24 hours) of the status and details of any such actions. The Company agrees not to release any third party from, or waive any provisions of, any confidentiality agreement to which it is a party or enter into any confidentiality agreement with any Person that would restrict the Company’s ability to provide information to Parent as required in this Article V.

(d) For purposes of this Agreement, “Acquisition Proposal” shall mean any proposal or offer, whether or not in writing, for the (i) direct or indirect acquisition or purchase of a business or assets that constitute 15% or more of the net revenues, net income or assets (based on the fair market value thereof) of the Company and its Subsidiaries, taken as a whole, (ii) direct or indirect acquisition or purchase of, or tender offer or exchange offer for, any equity securities or capital stock of the Company or any of its Subsidiaries that if consummated would result in any Person or Persons beneficially owning 15% or more of any class of equity securities of the Company or any of its Subsidiaries whose business constitutes 15% or more of the net revenues, net income or assets of the Company and its Subsidiaries, taken as a whole, or (iii) merger, consolidation, restructuring, share exchange, transfer of assets, recapitalization, or other business combination or similar transaction involving the Company or any of its Subsidiaries that if consummated would result in any Person or Persons beneficially owning 15% or more of any class of equity securities of the Company or any of its Subsidiaries whose business constitutes 15% or more of the net revenues, net income or assets of the Company and its Subsidiaries, taken as a whole, other than the transactions contemplated by this Agreement. The term “Superior Proposal” shall mean any bona fide written Acquisition Proposal that was not initiated, solicited, knowingly encouraged or facilitated by the Company or any of its Subsidiaries or any of their respective officers, directors, Employees, investment bankers, attorneys, accountants, financial advisors, agents or other representatives in violation of this Agreement, made by a third party to acquire, directly or indirectly, pursuant to a tender offer, exchange offer, merger, share exchange, consolidation, asset purchase or other business combination, (A) 50% or more of the assets of the Company and its Subsidiaries, taken as a whole, or (B) 50% or more of the equity securities of the Company, in each case on terms which the Company Board determines in good faith by resolution duly adopted (after consultation with its financial advisors and outside legal counsel, and taking into account all financial, legal and regulatory terms and conditions of the Acquisition Proposal and this Agreement, including any alternative transaction (including any modifications to the terms of this Agreement) proposed by Parent in response to such Superior Proposal, including any conditions to and expected timing of consummation, and any risks of non-consummation, of such Acquisition Proposal) to be reasonably likely to be completed on the terms proposed and is more favorable to the stockholders of the Company (in their capacity as stockholders) from a financial point of view as compared to the transactions contemplated hereby and to any alternative transaction (including any modifications to the terms of this Agreement) proposed by Parent pursuant to this Section 5.3; provided, however, that no proposal shall be deemed to be a Superior Proposal if such proposal is subject to a financing condition or

any financing required to consummate the proposal is not fully committed (unless it is reasonable to conclude that the proposed acquiror has adequate financial resources to consummate the transaction).

(e) Immediately after the execution and delivery of this Agreement, the Company shall, and shall cause its Subsidiaries and their respective officers, directors, Employees, investment bankers, attorneys, accountants, financial advisors, agents and other representatives to, cease and terminate any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any possible Acquisition Proposal. The Company agrees that it shall (i) take the necessary steps to promptly inform its officers, directors, Employees, investments bankers, attorneys, accountants, financial advisors, agents or other representatives involved in the transactions contemplated by this Agreement of the obligations undertaken in this Section 5.3 and (ii) request each Person who has heretofore executed a confidentiality agreement in connection with such Person’s consideration of acquiring the Company or any material portion thereof or any similar transaction to return or destroy (which destruction shall be certified in writing by an executive officer of such Person) all confidential information heretofore furnished to such Person by the Company or on its behalf to the extent such request is permitted or contemplated by such confidentiality agreement.

Section 5.4 Access to Information and Properties.

(a) Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each of the Company and Parent shall, and shall cause each of its Subsidiaries to, afford to the authorized representatives of the other party, including officers, Employees, accountants, counsel and other representatives of the other party, reasonable access, during normal business hours during the period prior to the Effective Time, to all of its properties, contracts, commitments, records, data and books and personnel and, during such period, it shall, and shall cause its Subsidiaries to, make available to the other parties all information concerning its business, properties and personnel as the other parties may reasonably request. No party nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of its customers, jeopardize any attorney-client privilege or contravene any Law or binding agreement entered into prior to the date of this Agreement. The Company and Parent will make appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

(b) From the date of this Agreement until the Effective Time, each party and its authorized representatives, including engineers, advisors and consultants, lenders and financing sources, upon reasonable notice and in a manner that does not unreasonably interfere with the business of the applicable party or any of its Subsidiaries, may enter into and upon all or any portion of the real property owned or leased by the other party in order to investigate and assess, as such party reasonably deems necessary or appropriate, the environmental condition of such real property and the other assets or the businesses of such other party or any of its Subsidiaries (an “Investigation”). Each party hereto shall, and shall cause each of its Subsidiaries to, cooperate with the other parties in conducting any such Investigation, facilitating further testing or evaluation as may be reasonably prudent with respect to matters identified in the investigation, allow any other party reasonable access to such party’s and its Subsidiaries’ respective businesses, real property and other assets, together with full permission to conduct any such

Investigation, and provide to any other party all plans, soil or surface or ground water tests or reports, any environmental investigation results, reports or assessments previously or contemporaneously conducted or prepared by or on behalf of such party, its Subsidiaries, or any of their predecessors that are in the possession of such party or any of its Subsidiaries, and all information relating to environmental matters regarding such party’s and its Subsidiaries’ respective businesses, real property and other assets that are in the possession of such party or any of its Subsidiaries. Under the terms of applicable operating agreements, access to Company Oil and Gas Properties and Parent Oil and Gas Properties which are operated by third parties may require such third-party operator’s prior approval and, where applicable, execution of such third-party operator’s customary boarding agreement. The Company (with respect to the Company Oil and Gas Properties) or Parent (with respect to the Parent Oil and Gas Properties) shall, upon request of the other party (the “Requesting Party”), request the third party operator’s approval for the Requesting Party to access and inspect the affected oil and gas properties. The Requesting Party shall repair any damage to the oil and gas properties resulting from such inspections and shall indemnify, defend and hold harmless the other party, its co-owners, Subsidiaries and its and their respective officers, directors, employees and agents from and against any and all claims, demands, losses, damages or causes of action arising from or relating to the Requesting Party’s inspection of the other party’s oil and gas properties, including, without limitation, claims of property damage, personal injury or death of any person arising from or relating to the Requesting Party’s inspection, regardless of the negligence, strict liability or other fault (but not gross negligence or willful misconduct) of the indemnified party.

(c) Parent and the Company will hold any information contemplated under this Sections 5.4 and any notices, agreements or information furnished pursuant to Section 5.3 in accordance with the provisions of the confidentiality agreement between the Company and Parent, dated as of January 6, 2012 (the “Confidentiality Agreement”).

(d) No investigation by Parent or the Company or their respective representatives shall affect the representations, warranties, covenants or agreements of the other set forth in this Agreement.

(d) In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and/or directors of the Surviving Company shall take or cause to be taken all such necessary action.

The headings, if any, of the individual sections of each of the Company Disclosure Letter and the Parent Disclosure Letter are inserted for convenience only and shall not be deemed to constitute a part thereof or a part of this Agreement. The Company Disclosure Letter and the Parent Disclosure Letter are arranged in sections corresponding to those contained in this Agreement merely for convenience, and the disclosure of an item in one section of the Company Disclosure Letter or the Parent Disclosure Letter as an exception to a particular representation or warranty shall be deemed adequately disclosed as an exception with respect to all other representations or warranties, notwithstanding the presence or absence of an appropriate section of the Company Disclosure Letter or the Parent Disclosure Letter with respect to such other representations or warranties or an appropriate cross reference thereto (but only to the extent an exception to a particular representation or warranty in one section of the Company Disclosure Letter or the Parent Disclosure Letter, as applicable, is disclosed in such a way as to make its relevance to such other representation or warranty reasonably apparent).

(c) The specification of any dollar amount in the representations and warranties or otherwise in this Agreement, the Parent Disclosure Letter or in the Company Disclosure Letter is not intended and shall not be deemed to be an admission or acknowledgement of the materiality of such amounts or items, nor shall the same be used in any dispute or controversy between the parties to determine whether any obligation, item or matter (whether or not described herein or included in any schedule) is or is not material for purposes of this Agreement.

Section 8.6 Headings; Schedules. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Each of the parties hereto further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in Section 8.4 shall be effective service of process for any claim, action, suit or other proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. The parties hereto hereby agree that a final, non-appealable judgment in any such claim, suit, action or other proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable Law.

Section 8.11 Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any of the parties hereto (whether by operation of Law or otherwise) without the prior written consent of the other parties; provided that Parent may assign this Agreement to any of its Subsidiaries or any Subsidiary or affiliate thereof.
