Section 2.4 Purchase Price Adjustment.

(a) As promptly as practicable after the Closing, but in no event more than forty-five (45) calendar days after the Closing Date, Purchaser shall in good faith prepare and deliver to Seller a statement (the “Closing Date Statement”) indicating Purchaser’s calculation of Net Working Capital, Net Closing Indebtedness, the Closing Capital Expenditures Difference, the Owned Crude Value and the components thereof and the resulting calculation of Purchase Price, as of the Closing, together with reasonable supporting detail.

(b) Until such time as the Final Closing Date Statement shall become final in accordance with clause (c) below, Purchaser and the Company shall permit Seller and its representatives reasonable access, during normal business hours, to the Books and Records and personnel of the Company and the Company Subsidiaries to aid in its review of the Closing Date Statement. Seller shall have the right to review the work papers of Purchaser and the Company underlying or utilized in preparing the Closing Date Statement and the calculation of Purchase Price, Net Working Capital, Net Closing Indebtedness, the Closing Capital Expenditures Difference and the Owned Crude Value set forth therein to the extent reasonably necessary to verify the accuracy of the Closing Date Statement and the calculation of Purchase Price, Net Working Capital, Net Closing Indebtedness, the Closing Capital Expenditures Difference and the Owned Crude Value in conformity with this Agreement.

(c) Within thirty (30) calendar days after its receipt of the Closing Date Statement, Seller shall either inform Purchaser in writing that the Closing Date Statement is acceptable or object thereto in writing, setting forth in reasonable detail a description of each of its objections. If Seller so objects and Purchaser and Seller do not resolve such objections on a mutually agreeable basis within thirty (30) calendar days after Purchaser’s receipt of Seller’s objections, the remaining disputed items shall be submitted to Deloitte LLP or, if Deloitte LLP is not available for such engagement or at the time of such proposed engagement is no longer independent, such other nationally recognized independent certified public accounting firm reasonably agreed to by Purchaser and the Seller (Deloitte LLP or such other accounting firm agreed to by Purchaser or the Seller or appointed as contemplated by the succeeding sentence, the “Accounting Firm”). If Purchaser and the Seller cannot agree on an accounting firm within ten (10) calendar days of determining that an Accounting Firm other than Deloitte LLP must be appointed as contemplated by the preceding sentence, then the Purchaser and/or Seller may submit a request to the American Arbitration Association requesting appointment of a nationally recognized independent certified public accounting firm to serve as Accounting Firm. Purchaser and Seller shall direct the Accounting Firm to resolve such disputed items within thirty (30) calendar days of submission of the disputed items. Upon the agreement of Purchaser and Seller, the decision of the Accounting Firm, or if Seller fails to deliver an objection to Purchaser within the first 30-day period referred to above, then the Closing Date Statement, as so adjusted (the “Final Closing Date Statement”), shall be final, conclusive and binding against the parties hereto. As set forth in the Final Closing Date Statement, the calculation of the Net Working Capital (“Final Net Working Capital”), Net Closing Indebtedness (“Final Net Closing Indebtedness”), the Closing Capital Expenditures Difference (the “Final Capital Expenditures Difference”), the Owned Crude Value (the “Final Owned Crude Value”) and resulting Final Purchase Price shall be final for all purposes hereunder.

(d) In resolving any disputed item, the Accounting Firm (i) shall be bound by the provisions of this Section 2.4, (ii) may not assign a value to any item greater than the greatest value claimed for such item or less than the smallest value for such item claimed by either Seller or Purchaser (except to the extent that the resolution of a disputed items results in a corresponding change to any other item), (iii) shall limit its decision to such items as are in dispute and (iv) shall make its determination based solely on presentations by Seller and Purchaser which are in accordance with the guidelines and procedures set forth in this Agreement (i.e., not on the basis of independent review). The fees, costs and expenses of the Accounting Firm shall be allocated by the Accounting Firm between Seller, on the one hand, and Purchaser, on the other hand, in the same proportion that the aggregate amount of the disputed items so submitted to the Accounting Firm are unsuccessfully disputed by each such party (as finally determined by the Accounting Firm) bears to the total amount of such disputed items so disputed.

(e) Within two (2) Business Days following the determination of the Final Purchase Price, Final Net Working Capital, Final Net Closing Indebtedness, Final Capital Expenditures Difference and Final Owned Crude Value in accordance with this Section 2.4:

(i) in the event that the Final Purchase Price exceeds the Estimated Purchase Price, (A) Purchaser shall deliver, or cause to be delivered, to Seller, by wire transfer of immediately available funds, payment in an amount equal to (x) the Final Purchase Price, minus (y) the Estimated Purchase Price and (B) Purchaser and Seller shall take all actions necessary under the Escrow Agreement to cause the Escrow Agent to release to Seller all amounts then contained in the Escrow Account;

(ii) in the event that the Estimated Purchase Price exceeds the Final Purchase Price, then Purchaser and Seller shall take all actions necessary under the Escrow Agreement to cause the Escrow Agent to (x) release to Purchaser from the Escrow Account an amount equal to (a) the Estimated Purchase Price, minus (b) the Final Purchase Price (or, if less, the amounts then contained in the Escrow Account), and (y) release to Seller from the Escrow Account all amounts remaining in such account, if any, after giving effect to the release to Purchaser pursuant to the foregoing clause (x).

Section 2.5 Purchase Price Allocation. The Purchase Price shall be allocated among the assets of the Company and the Company Subsidiaries in a manner to be mutually agreed by the Seller and Purchaser in a manner consistent with Section 1060 of the Code, as amended, and the Treasury regulations promulgated thereunder. Within 120 days of the Closing, Purchaser shall deliver to Seller a draft allocation for Seller’s review and approval. Seller and Purchaser shall negotiate in good faith to resolve any issues; provided that any issues not finally resolved within 60 days of the Closing shall be referred to the Accounting Firm, whose determination shall be final and binding on the parties. Seller and Purchaser agree to use the allocations determined pursuant to this Section 2.5 for all tax purposes, including those matters subject to Section 1060 of the Code, as amended, and the Treasury regulations promulgated thereunder, unless otherwise required by law. The parties shall amend the final allocation, as necessary and in a manner consistent with the allocation contained therein, to reflect any differences between the Purchase Price and the Final Purchase Price, as determined pursuant to Section 2.4.

ARTICLE 4

REPRESENTATIONS AND WARRANTIES OF PURCHASER

Except as set forth in the Purchaser Disclosure Schedules, Purchaser represents and warrants to Seller as of the Execution Date and as of the Closing Date as follows:

Section 4.1 Status and Authority. Purchaser is a limited partnership duly organized, validly existing and in good standing under the laws of Delaware and has the necessary power and authority to execute and deliver this Agreement and the other Transaction Documents and perform its obligations hereunder and thereunder. The execution, delivery and performance of

this Agreement and the other Transaction Documents and the consummation of the transactions contemplated hereby and thereby have been duly authorized by all necessary limited partnership action on the part of Purchaser. This Agreement has been, and the other Transaction Documents will at the Closing be, duly executed and delivered by Purchaser and, assuming the due authorization, execution and delivery of Seller and/or the other parties hereto and thereto, this Agreement constitutes, and the other Transaction Documents when so executed and delivered by Purchaser will constitute, the legal, valid and binding obligation of Purchaser, enforceable against Purchaser in accordance with its terms, except as may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws affecting the enforcement of creditors’ rights generally or by general equitable principles.

Section 4.2 No Conflicts; Consents and Approvals.

(a) Assuming expiration or termination of the waiting period under the HSR Act, the execution, delivery and performance by Purchaser of this Agreement and the other Transaction Documents will not result in (i) any conflict with the Organizational Documents of Purchaser, (ii) any breach or violation of or default under, or constitute or give rise to a termination or right of termination of, acceleration of any obligation or loss of any benefit under, any contract, mortgage, lease, agreement, deed of trust, indenture or any other instrument to which Purchaser is a party or by which Purchaser or any of its properties or assets are bound, (iii) a violation of or default under any Law or Governmental Authorization to which Purchaser is subject or (iv) the creation or imposition of any Lien, except, in the case of the foregoing clauses (ii), (iii) and (iv) as would not, individually or in the aggregate, be reasonably expected to materially impede or delay the Closing or the ability of Purchaser to fulfill its obligations hereunder.

(b) Except for the filing of a Notification and Report Form under the HSR Act and the expiration or termination of the waiting period under the HSR Act, no Governmental Authorization of or filing with any Governmental Authority is required on the part of Purchaser in connection with the execution and delivery of this Agreement or the other Transaction Documents or the consummation of the transactions contemplated hereby or thereby (other than filings made pursuant to the Securities Exchange Act of 1934, as amended).

Section 4.3 Financing. The amount of funds contemplated to be provided pursuant to the Debt Commitment Letter (as defined below) will be sufficient to (a) pay the aggregate Purchase Price (including any adjustment amount pursuant to Section 2.4) and other amounts required to be paid pursuant to Section 2.3(b), (b) pay any and all fees and expenses required to be paid by Purchaser and its Affiliates in connection with the transactions contemplated by this Agreement, including in connection with the Debt Financing and (c) consummate the transactions contemplated by this Agreement and perform Purchaser’s obligations hereunder (such amount of funds, the “Sufficient Financing Amount”). Purchaser has furnished Seller and the Company with true, complete and correct copies of (a) the executed and binding Commitment Letter, dated as of the date hereof among Purchaser and Mizuho Bank, Ltd. (the “Debt Financing Sources”), pursuant to which the Debt Financing Sources have committed, subject to the terms and conditions set forth therein, to lend the amounts set forth therein for the purposes of financing the transactions contemplated by this Agreement, and (b) each executed fee letter and engagement letter associated therewith that contain any conditions to funding or

“flex” provisions or other provisions (as redacted in a customary manner with respect to fees) (provided that prior to the execution of this Agreement, Purchaser has advised Seller and the Company of the maximum amount of fees and expenses payable by Purchaser in connection with the Debt Financing) regarding the terms and conditions of the financing to be provided by such commitment letter (such commitment letter, including all exhibits, schedules, annexes and amendments thereto, and each such fee letter and engagement letter, collectively, the “Debt Commitment Letter”) (the “Debt Financing”). The Debt Commitment Letter has not been amended or modified prior to the date of this Agreement, no such amendment or modification is contemplated, and the commitments contained in the Debt Commitment Letter have not been withdrawn or rescinded in any respect. Except for the fee letters and engagement letters referenced above, there are no side letters or other agreements, Contracts or arrangements related to the funding or investing, as applicable, of the full amount of the Debt Financing other than as expressly set forth in the Debt Commitment Letter delivered to Seller and the Company prior to the date hereof, and there are no conditions precedent or other contingencies related to the funding of the full amount of the Debt Financing other than as expressly set forth in the Debt Commitment Letter and delivered to Seller and the Company prior to the date hereof. As of the date hereof, the Debt Commitment Letter is in full force and effect. The Debt Commitment Letter is (a) a legal, valid and binding obligation of Purchaser and to the Knowledge of Purchaser, each of the other parties thereto and (b) enforceable in accordance with its terms against Purchaser and, to the Knowledge of Purchaser, each of the other parties thereto except as may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar Laws affecting the enforcement of creditors’ rights generally or by general equitable principles. No event has occurred which, with or without notice, lapse of time or both would or would reasonably be expected to constitute a default or breach on the part of Purchaser or, to the Knowledge of Purchaser, any other party thereto under the Debt Commitment Letter. All commitments and other fees or expenses required to be paid under the Debt Commitment Letter prior to the date hereof have been fully paid. As of the Execution Date, to the Knowledge of Purchaser, there is no fact or occurrence existing that would make any of the statements (including assumptions) set forth in the Debt Commitment Letter inaccurate in any material respect. As of the date hereof, Purchaser has no reason to believe that any of the conditions to the funding of the Debt Financing contemplated by the Debt Commitment Letter will not be satisfied or that the Debt Financing will not be made available to Purchaser on or prior to the Closing Date. In no event shall the receipt or availability of the Debt Financing or any other funds or financing by Purchaser or any Affiliate or any other transactions be a condition to any of Purchaser’s obligations hereunder.

Section 4.4 Solvency. Assuming the satisfaction of the conditions set forth in Section 7.1 and Section 7.3, immediately after giving effect to the transactions contemplated by this Agreement, the Company and each of the Company Subsidiaries will be Solvent. No transfer of property is being made and no obligation is being incurred by or at the direction of Purchaser in connection with the transactions contemplated by this Agreement with the intent to hinder, delay or defraud any present or future creditors of the Company or the Company Subsidiaries. For purposes of this Agreement, “Solvent” when used with respect to the Company, means that, as of any date of determination from and after the Closing Date, (i) the Present Fair Salable Value of its assets will, as of such date, exceed all of its liabilities, contingent or otherwise, as of such date, (ii) the Company will not have, or have access to, as of such date, an unreasonably small amount of capital for the business in which it is engaged or will be engaged and (iii) the

Company will be able to pay its debts as they become absolute and mature, in the ordinary course of business, taking into account the timing of and amounts of cash to be received by it and the timing of and amounts of cash to be payable on or in respect of its indebtedness, in each case after giving effect to the transactions contemplated by this Agreement. For purposes of the definition of “Solvent” (A) “debt” means liability on a “claim”; and (B) “claim” means (x) any right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, secured or unsecured or (y) the right to an equitable remedy for a breach in performance if such breach gives rise to a right to payment, whether or not such equitable remedy is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured. “Present Fair Salable Value” means the amount that may be realized if the aggregate assets of the Company (including goodwill) are sold as an entirety with reasonable promptness in an arm’s-length transaction under present conditions for the sale of comparable business enterprises.

Section 4.5 Litigation. As of the Execution Date, there is no Litigation pending or, to the Knowledge of Purchaser, threatened, which questions the validity of this Agreement or any action taken or to be taken by Purchaser in connection herewith which would materially impair or delay Purchaser’s ability to complete the transactions contemplated by this Agreement in accordance with the terms hereof.

Section 4.6 Purchase for Investment. Purchaser is acquiring the Transferred Interests for investment and not with a view toward, or for offer or sale in connection with, any resale or public distribution thereof in violation of the U.S. Securities Act of 1933, as amended, or any state or non-U.S. Law of similar effect. Purchaser acknowledges that the Transferred Interests will not be registered under the U.S. Securities Act of 1933, as amended, or any state or non-U.S. Law of similar effect.

Section 4.7 Brokers. Neither Purchaser nor any of its Affiliates has entered, directly or indirectly, into any Contract or arrangement with any Person that would obligate Seller to pay any commission, brokerage or “finder’s fee” or other fee in connection with this Agreement, the other Transaction Documents or the transactions contemplated hereby or thereby.

Section 4.8 No Knowledge of Representations or Omissions. To the Knowledge of Purchaser, there are no representations and warranties of Seller in this Agreement that are not true and correct in all material respects, and Purchaser has no Knowledge of any material errors in, or material omissions from, the Seller Disclosure Schedules, or any other Schedules.

Section 4.9 Purchaser’s Examination. Purchaser has been given adequate opportunity to examine all documents provided by, conduct due diligence and ask questions of, and to receive answers from, Seller and its representatives concerning the Company, the Company Subsidiaries, and the business, assets, properties and liabilities of the Company and the Company Subsidiaries and Purchaser’s investment in the Transferred Interests, and Purchaser has completed its own independent investigation, analysis and evaluation of the Company, the Company Subsidiaries, and the business, assets, properties and liabilities of the Company and the Company Subsidiaries as it deemed necessary or appropriate.

Section 5.5 Financing.

(a) Purchaser hereby acknowledges and agrees that obtaining the Debt Financing is not a condition to the Closing. For the avoidance of doubt, if the Debt Financing is not available, Purchaser shall continue to be obligated, subject to the fulfillment or waiver of the conditions to the obligation of Purchaser set forth in Section 7.1 and Section 7.3, to complete the transactions contemplated by this Agreement on the terms contemplated by this Agreement.

(b) Purchaser shall take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to arrange and obtain the Debt Financing on the terms and conditions described in the Debt Commitment Letter, including (i) maintaining in effect the Debt Commitment Letter, (ii) satisfying on a timely basis all conditions applicable to

Purchaser obtaining the Debt Financing and complying with its obligations in the Debt Commitment Letter, (iii) entering into definitive agreements with respect thereto on terms and conditions described in or contemplated by the Debt Commitment Letter (including any “flex” provisions in the Debt Commitment Letter), (iv) obtaining such third-party consents as may be reasonably required in connection with the Debt Financing and (v) consummating the Debt Financing at or prior to the Closing (including by taking enforcement actions against the Debt Financing Sources and other Persons providing the Debt Financing, including through litigation). Purchaser shall not agree to or permit any amendment, supplement or other modification of, or waive any of its rights under, the Debt Commitment Letter or any definitive agreements related to the Debt Financing, in each case, without Seller’s prior written consent, except to correct typographical errors, provide for the assignment of a portion of the Debt Commitment Letter to additional agents or arrangers or to reallocate commitments or assign or reassign titles or roles to, or between or among, any entities party thereto. Purchaser shall promptly upon execution deliver to Seller copies of any such amendment, replacement, supplement, modification or waiver. Upon any such amendment, supplement or modification of the Debt Commitment Letter in accordance with this Section 5.5, the term “Debt Commitment Letter” shall mean the Debt Commitment Letter as so amended, supplemented or modified. Without limiting any of the foregoing obligations of Purchaser except as set forth below, it is understood that Purchaser shall be entitled to seek equity or debt financing from alternative sources the proceeds of which may be used in lieu of the Debt Financing to finance all or a portion of the Sufficient Financing Amount so long as any such proceeds obtained prior to the Closing Date are used to consummate the transactions contemplated by this Agreement (the “Replacement Financing”) or used prior to the Closing to repay outstanding amounts under Purchaser’s existing revolving credit facility so long as Purchaser has no reason to believe that any of the conditions to the drawdowns of such revolving credit facility would not be satisfied as of the Closing and Purchaser will have capacity under such revolving credit facility to redraw any such amounts at the Closing to the extent necessary to consummate the transactions contemplated by this Agreement. To the extent Purchaser obtains and uses the proceeds of such Replacement Financing to pay all of the payments set forth in Section 2.2 and any adjustment pursuant to Section 2.4 and any other amounts required to be paid pursuant to Section 2.3(b), Purchaser shall be relieved of its obligation under Section 5.5(b)(v) to consummate the Debt Financing at or prior to the Closing to the extent the Debt Financing is not necessary for the Purchaser to consummate the transactions contemplated by this Agreement.

(c) In the event all or any portion of the Debt Financing becomes unavailable on the terms and conditions described in or contemplated by the Debt Commitment Letter for any reason, Purchaser shall use its reasonable best efforts to arrange to obtain, as promptly as practicable following the occurrence of such event but no later than the satisfaction or waiver of the conditions to the obligation of Purchaser set forth in Section 7.1 and Section 7.3, alternative financing from alternative sources (the “Alternative Financing”) in an amount equal to the Sufficient Financing Amount, which would not involve terms that are materially less favorable to Purchaser, would not involve any conditions to funding the Debt Financing that are not contained in the Debt Commitment Letter, would not reasonably be expected to prevent, impede or delay the consummation of the Debt Financing or the transactions contemplated by this Agreement and would not adversely impact the ability of Purchaser or Seller, as applicable, to enforce its rights against other parties to the Debt Commitment Letter or otherwise adversely impact the Seller. The obligations under this Section 5.5 shall apply equally to any such Alternative Financing (including any new financing commitment).

(d) Purchaser shall keep Seller and the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to arrange the Debt Financing (or Alternative Financing or Replacement Financing) and provide to Seller and the Company copies of all documents related to the Debt Financing (or Alternative Financing or Replacement Financing). Purchaser shall allow Seller and the Company to reasonably consult with the providers of the Debt Financing (and Alternative Financing or Replacement Financing) on the status of such financing (provided that Purchaser shall have the right to have one or more representatives present during any such consultation) and provide Seller and the Company, upon reasonable request, with such information and documentation as shall be reasonably necessary to allow Seller and the Company to monitor the progress of such financing activities. Without limiting the generality of the foregoing, Purchaser shall give Seller and the Company prompt written notice (i) of any actual or purported breach, default, repudiation, cancellation or termination (or any event or circumstance that, with or without notice, lapse of time or both, could reasonably be expected to give rise to such breach, default, repudiation, cancellation or termination) by any party to the Debt Commitment Letter (or commitments for any Alternative Financing or Replacement Financing) or definitive documents relating to the Debt Financing (or any Alternative Financing or Replacement Financing) of which Purchaser becomes aware or any termination of the Debt Commitment Letter (or commitments for any Alternative Financing or Replacement Financing), (ii) if for any reason Purchaser believes in good faith that there is a possibility that it will not be able to obtain all or any portion of the Debt Financing (or any Alternative Financing or Replacement Financing) on the terms, in the manner or from the sources contemplated by the Debt Commitment Letter (and any equivalent documents for any Alternative Financing or Replacement Financing) or the definitive documents related to the Debt Financing (and any equivalent documents for any Alternative Financing or Replacement Financing), (iii) if for any reason Purchaser believes in good faith that there is a possibility that it will not be able satisfy the conditions necessary to obtain the Sufficient Financing Amount under the Debt Commitment Letters (or any equivalent documents for any Alternative Financing or Replacement Financing) or (iv) any reduction in the amount of the commitments under the Debt Commitment Letters (or any equivalent documents for any Alternative Financing or Replacement Financing). The Purchaser will not consent to any assignment of rights or obligations under the Debt Commitment Letters (or any equivalent documents for any Alternative Financing or Replacement Financing) without the prior written approval of the Seller, which shall not be unreasonably withheld or delayed.

Section 6.5 Transfer Taxes. Purchaser agrees to be fully responsible for and pay all Transfer Taxes (if any) that may be due and payable in connection with the transfer of the Transferred Interests contemplated by this Agreement, whether before, at, or after Closing.

Section 6.6 Further Assurances. Seller and Purchaser each agree that from time to time after the Closing they will execute and deliver, and will cause their respective Affiliates to execute and deliver, such further instruments, and take, and cause their respective Affiliates to take, such other actions as may be reasonably necessary to carry out the purposes and intent of this Agreement.

Section 6.7 Indemnification; Directors’ and Officers’ Insurance. (a) From and after the Closing, Purchaser shall cause the Company and the Company Subsidiaries (as applicable, the “D&O Indemnifying Party”) to indemnify, defend and hold harmless each person who is now, or has been at any time prior to the date hereof or who becomes prior to the Closing, an officer or director of the Company or any of the Company Subsidiaries (the “D&O Indemnified Parties”) against all losses, claims, damages, costs, expenses (including attorneys’ fees and expenses), liabilities or judgments or amounts that are paid in settlement with the approval of the D&O Indemnifying Party (which approval shall not be unreasonably withheld) of or in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, based in whole or in part on or arising in whole or in part out of the fact that such person is or was a director or officer of the Company or any of the Company Subsidiaries whether pertaining to any matter existing or occurring prior to the Closing or any acts or omissions occurring or existing prior to the Closing and whether asserted or claimed prior to, or at or after, the Closing, in each such case, to the same extent such D&O Indemnified Parties are entitled thereto as of the date hereof. Furthermore, the current provisions in the Company’s and the Company Subsidiaries’ respective Organizational Documents with respect to exculpation of director and officer liability and indemnification shall not be amended for six years following the Closing if such amendment would materially and adversely affect the rights thereunder of individuals who at any time prior to the Closing were directors or officers of the Company or any of the Company Subsidiaries in respect of actions or omissions occurring at or prior to the Closing.

(b) For a period of six years after the Closing, Purchaser shall cause the Company and the Company Subsidiaries to maintain in effect the current policies of directors’ and officers’ liability insurance maintained by the Company and the Company Subsidiaries; provided that Purchaser may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are no less advantageous to the D&O Indemnified Parties with respect to matters arising before and acts or omissions occurring or existing at or prior to the Closing; provided, further, that the Company and the Company Subsidiaries shall not be obligated to pay annual premiums in excess of 300% of the annual premiums currently paid for such insurance. Purchaser may satisfy its obligations under this Section 6.7(b) by purchasing a “tail” policy which (i) has an effective term of six years from the Closing, (ii) covers each person currently covered by the Company’s directors’ and officers’ insurance policy in effect on the date of this Agreement for actions and omissions occurring on or prior to the Closing, and (iii) contains terms that are no less favorable than those of the Company’s directors’ and officers’ insurance policy in effect on the date of this Agreement.

(c) In the event that, following the Closing, the Purchaser or the Company or any of their respective successors or assigns (i) consolidates or merges with or 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, proper provision shall be made so that the successors and assigns of the Purchaser or the Company shall assume and succeed to all of the obligations thereof set forth in this Section 6.7. In addition, following the Closing, the Purchaser and the Company shall not distribute, sell, transfer or otherwise dispose of any of their assets in a manner that would reasonably be expected to render the Purchaser or the Company unable to satisfy their obligations under this Section 6.7.

(d) The provisions of this Section 6.7 are intended to be for the benefit of, and shall be enforceable by, each D&O Indemnified Party, his or her heirs and his or her personal representatives and shall be binding on all successors and assigns of Purchaser, the Company and the Company Subsidiaries.

Section 6.8 Post-Closing Access. In connection with any matter relating to any period prior to, or any period ending on, the Closing Date, Purchaser shall, upon the request and at the expense of Seller, permit Seller and its representatives reasonable access at all reasonable times to the Books and Records transferred to Purchaser, and Purchaser shall execute and shall cause the Company and the Company Subsidiaries to execute such documents as Seller may reasonably request to enable Seller to prepare and/or file any reports or Tax Returns required of Seller and/or any of Seller’s Affiliates, if any, relating to the Company or any of the Company Subsidiaries, or for Seller to fulfill any post-Closing Obligations hereunder. Purchaser shall not dispose of such Books and Records during the seven (7)-year period beginning with the Closing Date without Seller’s consent, which shall not be unreasonably withheld, conditioned or delayed.

Section 6.9 Name Change; Use of Name. Purchaser shall change the name of the Company and the Company Subsidiaries within 60 days following the Closing Date to exclude the word “Navigator”, and shall cease using such name after such time. On and prior to the date that is 60 days following the Closing Date, Purchaser shall have a nonexclusive, non-assignable, non-sublicensable license to continue using such name, in a manner consistent with past practice and transitional “phase out” use.

Section 6.10 Transition Matters.

(a) From time to time prior to Closing, but in no event later than three Business Days prior to the Closing Date, Purchaser may deliver to Seller a notice providing the name or names of any current Employee(s) (each such Employee, a “Terminated Employee”) to be terminated effective upon the Closing, and Seller shall, subject to compliance with applicable Law, cause the employment of such Terminated Employees to be terminated effective upon the Closing. If any such Terminated Employee has previously executed a Transition Services Letter, Seller shall cause such Transition Services Letter to be terminated effective upon the Closing.

(b) From time to time prior to the Closing, but in no event later than three Business Days prior to the Closing Date, Purchaser may deliver to Seller a notice providing the name or names of any current Employee(s) (each such Employee, a “Targeted Employee”) that Purchaser has identified for the execution of a Transition Services Letter. Seller shall then request that the Targeted Employee enter into a Transition Services Letter with the Company on or prior to Closing.

Section 9.3 Consent to Jurisdiction. (a) Each of the parties hereto hereby irrevocably and unconditionally (i) submits, for itself and its property, to the exclusive jurisdiction of the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware), and any appellate court from any thereof, in any action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind arising out of or relating to this Agreement, any certificate, instrument, opinion or other documents delivered hereunder, or the negotiation, execution or performance hereof or thereof (including any action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind based upon, arising out of or related to any representation or warranty made in or in connection herewith or therewith), or for recognition or enforcement of any judgment, and agrees that all claims in respect of any such action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind shall be heard and determined in such Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any Federal court of the United States of America sitting in the State of Delaware), (ii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind arising out of or relating to this Agreement, any certificate, instrument, opinion or other documents delivered hereunder, or the negotiation, execution or performance hereof or thereof (including any action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind based upon, arising out of or related to any representation or warranty made in or in connection herewith or therewith) in the Delaware Court of Chancery, any Federal court of the United States of America sitting in the State of Delaware, or in any Delaware State court, (iii) waives, to the fullest extent permitted by Law, the defense of an inconvenient forum to the maintenance of such action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind in any such court and (iv) agrees that a final judgment in any such action, cause of action, claim, cross-claim or third-party claim or Litigation of any kind shall be conclusive and

may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

Section 9.4 Remedies. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate the transactions contemplated by this Agreement) in accordance with its specified terms or otherwise breach such provisions. It is accordingly agreed that the Parties shall be entitled to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof (including by requiring Purchaser to file one or more lawsuits against the Debt Financing Sources to fully enforce the Debt Financing Sources’ obligations under the Debt Commitment Letter), this being in addition to any other remedy to which they are entitled at Law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that the Party seeking the injunction, specific performance and other equitable relief has an adequate remedy of Law. The remedies available to each Party pursuant to this Section 9.4 shall be in addition to any other remedy to which it is entitled at Law or in equity. To the extent any party hereto brings any action to enforce specifically the performance of the terms and provisions of this Agreement (other than an action solely to specifically enforce any provision that expressly survives termination of this Agreement pursuant to Section 8.2 hereof) when available to such party pursuant to the terms of this Agreement, the Termination Date shall automatically be extended by (i) the amount of time during which such action is pending, plus 20 Business Days, or (ii) such other time period established by the court presiding over such action.

Section 9.5 Modification; Waiver. This Agreement may be modified only by a written instrument executed by the Parties hereto. Any of the terms and conditions of this Agreement may be waived in writing (subject to applicable Law) at any time on or prior to the Closing Date by the Party entitled to the benefits thereof. To the extent any amendment, modification or supplement to Section 9.2, Section 9.3, this Section 9.5 or Section 9.9 is sought which is adverse to the rights of any Debt Financing Source, the prior written consent of such Debt Financing Source shall be required before such amendment, modification or supplement is effective.

Section 9.6 Entire Agreement. This Agreement constitutes the entire agreement of the Parties with respect to the subject matter hereof and supersede all other prior agreements and understandings, oral or written, express or implied, between the Parties hereto and their respective Affiliates, representatives and agents in respect of the subject matter hereof, except that this Agreement does not supersede the Confidentiality Agreement, the terms and conditions of which the Parties hereto expressly reaffirm.

Section 9.7 Severability. If any term or other provision of this Agreement is found to be, by competent authority with jurisdiction, invalid, illegal or incapable of being enforced by any rule of Law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either Party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties hereto as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 9.8 Expenses. Except as expressly provided herein to the contrary, whether or not the transactions contemplated herein shall be consummated, each Party shall pay its own expenses incident to the preparation and performance of this Agreement.

Section 9.9 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each Party hereto and its successors and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement; provided that: (i) the Debt Financing Sources shall be considered third party beneficiaries with respect to Section 9.2, Section 9.3, Section 9.5 and this sentence of Section 9.9, (ii) the D&O Indemnified Parties shall be considered third party beneficiaries of Section 6.7, (iii) the Seller Related Parties shall be considered third party beneficiaries of Section 6.4, (iv) the Non-Party Affiliates shall be considered third party beneficiaries of Section 9.18 and (v) ST&B shall be considered a third party beneficiary of Section 9.19, and, in each case, such parties shall have the right to enforce such Sections.

Section 9.10 Failure or Indulgence Not Waiver. No failure or delay on the part of any Party hereto in the exercise of any right hereunder shall impair such right or be construed to be a waiver of, or acquiescence in, any breach of any representation, warranty, covenant or agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof, or of any other right.

Section 9.11 Notices. All notices, requests, demands and other communications hereunder shall be in writing and shall be deemed to have been duly given or made as follows: (i) if sent by registered or certified mail, return receipt requested, upon receipt; (ii) if sent by reputable overnight air courier (such as DHL or Federal Express), upon receipt; (iii) if sent by email or facsimile transmission, with a copy mailed on the same day in the manner provided in (i) or (ii) above, when transmitted and, in the case of facsimile transmission, when receipt is confirmed; or (iv) if otherwise actually personally delivered, when delivered and shall be delivered as follows:

Except as expressly set forth in the Confidentiality Agreement or the Escrow Agreement, all claims, obligations, liabilities, or causes of action (whether at Law, in equity, in contract, in tort or otherwise) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement, or the negotiation, execution, or performance of this Agreement (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement), may be made only against (and such representations and warranties are those solely of) the Parties. No Person who is not a Party, including any current, former or future equityholder,

incorporator, controlling person, general or limited partner, member, Affiliate, assignee or representative of any Party, or any current, former or future equityholder, incorporator, controlling person, general or limited partner, Affiliate, assignee or representative of any of the foregoing or any of their respective successors, predecessors or assigns (or any successors, predecessors or assigns of the foregoing) (collectively, the “Non-Party Affiliates”), shall have any liability (whether in Law or in equity, whether in contract or in tort or otherwise) for any claims, causes of action, obligations, or liabilities arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance, or breach (other than as expressly set forth in the Confidentiality Agreement or the Escrow Agreement), and, to the maximum extent permitted by Law, each Party hereby waives and releases all claims, causes of action, obligations, or liabilities arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance, or breach (other than as expressly set forth in the Confidentiality Agreement or the Escrow Agreement) against any such Non-Party Affiliates. Without limiting the foregoing, to the maximum extent permitted by Law, except to the extent otherwise expressly set forth in the Confidentiality Agreement or the Escrow Agreement, (a) each Party hereby waives and releases any and all rights, claims, demands, or causes of action that may otherwise be available, whether at Law, in equity, in contract, in tort or otherwise, to avoid or disregard the entity form of a Party or otherwise impose liability of a Party on any Non-Party Affiliate, whether granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization, or otherwise, in each case arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance, or breach (other than as expressly set forth in the Confidentiality Agreement or the Escrow Agreement); and (b) each Party disclaims any reliance upon any Non-Party Affiliates with respect to the performance of this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement. Notwithstanding anything to the contrary contained herein or otherwise, after the Closing, no party may seek to rescind this Agreement or any of the transactions contemplated hereby.

Section 9.19 Provision Respecting Legal Representation. Purchaser (on its behalf and, from and after the Closing, on behalf of the Company Group) hereby waives, and agrees to cause its Affiliates to waive, any conflicts that may arise in connection with ST&B representing the Seller or any Seller Related Party after the Closing as such representation may relate to Purchaser, the Company Group or the transactions contemplated by this Agreement. Purchaser (on its behalf and, from and after the Closing, on behalf of the Company Group) hereby agrees that, in the event that a dispute arises after the Closing between the Purchaser or the Company Group, on the one hand, and Seller or any Seller Related Party, on the other hand, ST&B may represent any or all of Seller or any Seller Related Party in such dispute even though the interests of Seller or the Seller Related Parties may be directly adverse to Purchaser, the Company Group or any of their respective Affiliates, and even though ST&B formerly may have represented the Company Group in a matter substantially related to such dispute. In addition, all communications involving attorney-client confidences by Seller, the Company Group or the Seller Related Parties in the course of the negotiation, documentation and consummation of the transactions contemplated hereby shall be deemed to be attorney-client confidences that belong solely to Seller and the Seller Related Parties (and not Purchaser or the Company Group). Accordingly,

Purchaser and the Company Group shall not have access to any such communications, or to the files of ST&B relating to the engagement described in this Section 9.19, whether or not the Closing shall have occurred. Without limiting the generality of the foregoing, upon and after the Closing, (i) Seller and the Seller Related Parties (and not Purchaser, the Company Group or their respective Affiliates) shall be the sole holders of the attorney-client privilege with respect to such engagement, and none of Seller, the Company Group or their respective Affiliates shall be a holder thereof, (ii) to the extent that the files of ST&B in respect of such engagement constitute property of the client, only Seller and the Seller Related Parties (and not Purchaser, the Company Group or their respective Affiliates) shall hold such property rights and (iii) ST&B shall have no duty whatsoever to reveal or disclose any such attorney-client communications or files to Purchaser, the Company Group or their respective Affiliates by reason of any attorney-client relationship between ST&B and any of Purchaser, the Company Group or their respective Affiliates or otherwise.

Section 9.20 Guarantee. To induce Seller to enter into this Agreement, Guarantor, intending to be legally bound, hereby absolutely, unconditionally and irrevocably guarantees to Seller the due and punctual performance, payment and discharge (and not merely collection) of all obligations of Purchaser under this Agreement, including payment of the aggregate Purchase Price (including any adjustment amount pursuant to Section 2.4) and other amounts required to be paid pursuant to Section 2.3(b)) when due and payable hereunder.
