Attached as Schedule 2.4 is a template for the calculation of the Estimated Capital Expenditures for January 1, 2011 through the Closing Date. In preparing the statements described in this Section 2.4, Sellers shall keep Buyer reasonably informed and, within ten (10) Business Days prior to the Closing Date, provide Buyer with a reasonable opportunity to review and comment on such statements (and the schedules, documentation, invoices and other relevant information supporting the calculations set forth therein).

Section 2.5 Post-Closing Purchase Price Reconciliation.

(a) Prior to or on the date that is sixty days after the Closing Date, Buyer shall prepare and deliver to Sellers a statement (the “Adjustment Statement”) that shall set forth Buyer’s good faith calculation, as of 12:01 a.m. Houston time on the Closing Date, of (i) Net Working Capital based on the Audited 2010 Financial Statements (updated to include information from January 1, 2011 through the Closing) and consistent with the methodology set forth on Schedule 1.1(c) (the “Closing Net Working Capital”) and (ii) the aggregate amount of the capital expenditures customarily capitalized under GAAP (but expressly excluding any capitalized interest or any capital expenditures for any Pad Gas delivered by BP North America, Inc. to the Facility in January 2011) that are permitted to be incurred pursuant to Section 6.1(a)(y)(v) and that have been incurred and paid (or otherwise recorded as a liability) by the Company during the period from and including January 1, 2011 until the Closing (the “Closing Capital Expenditures”). Buyer’s calculation of the Closing Net Working Capital and the Closing Capital Expenditures shall be determined in accordance with GAAP applied using the accounting principles, practices and methods that were used in the preparation of the Audited 2010 Financial Statements and, with respect to the Closing Net Working Capital, consistent with the methodology set forth on Schedule 1.1(c). In preparing the statements described in this

Section 2.5(a), Buyer shall keep Sellers reasonably informed and, within five (5) Business Days prior to the date that is sixty days after the Closing Date, provide Sellers with a reasonable opportunity to review and comment on such statements (and the schedules, documentation, invoices and other relevant information supporting the calculations set forth therein).

(b) After receipt of the Adjustment Statement, Sellers shall have thirty (30) days to review the factual basis, mathematical calculations and accounting methods used therein. On or prior to the thirtieth (30th) day after receipt of the Adjustment Statement, Sellers shall deliver written notice to Buyer specifying any disputed items (the “Initial Reconciliation Disputes”) and the basis therefor and amount thereof. Any such notice shall include only Initial Reconciliation Disputes based on (i) errors of fact underlying the determination of the Closing Net Working Capital or the Closing Capital Expenditures, (ii) mathematical errors in the computation of the Closing Net Working Capital or the Closing Capital Expenditures and (iii) failures to determine the Closing Net Working Capital or the Closing Capital Expenditures in accordance with this Agreement. If Sellers fail to notify Buyer of any Initial Reconciliation Disputes on or prior to the thirtieth (30th) day after receipt of the Adjustment Statement, then all calculations and valuations of the Closing Net Working Capital and the Closing Capital Expenditures set forth on the Adjustment Statement shall be deemed accepted by Sellers and shall be final, binding, conclusive and nonappealable for all purposes of this Agreement.

(c) If Sellers notify Buyer of any Initial Reconciliation Disputes in accordance with Section 2.5(b), then Buyer and Sellers shall, over the ten (10) days following the date of such notice (the “Resolution Period”), attempt in good faith to resolve the Initial Reconciliation Disputes and any written resolution by them as to any disputed item shall be final, binding, conclusive and nonappealable for all purposes of this Agreement. If, at the conclusion of the Resolution Period, Buyer and Sellers have not reached an agreement on the disputed items, then all Initial Reconciliation Disputes then remaining in dispute (the “Final Reconciliation Disputes”) shall be submitted by Sellers and Buyer to a nationally recognized independent auditor that is not the independent auditor for any Party or their respective Affiliates and as to which the Parties shall reasonably agree prior to expiration of the Resolution Period (the “Neutral Auditor”). All fees and expenses relating to the work, if any, to be performed by the Neutral Auditor pursuant to this Section 2.5 shall be borne by Sellers, on the one hand, and by Buyer, on the other hand, based upon the percentage that the amount not ultimately awarded to such Party by the Neutral Auditor bears to the amount actually contested by such Party in the Final Reconciliation Disputes. Except as provided in the preceding sentence, all other costs and expenses incurred by the Parties in connection with resolving any Final Reconciliation Disputes hereunder before the Neutral Auditor shall be borne by the Party incurring such cost and expense. With respect to each disputed line item of the Closing Net Working Capital or the Closing Capital Expenditures, the Neutral Auditor’s final determination, if not in accordance with the position of either Sellers or Buyer, will not be in excess of the higher, nor less than the lower, of the amounts advocated by Buyer in its calculation of the Closing Net Working Capital and the Closing Capital Expenditures or the corresponding amounts claimed by Sellers in their initial notice of dispute delivered by Sellers pursuant to Section 2.5(b). For the avoidance of doubt, the Neutral Auditor shall not review any line items or make any determination with respect to any matter other than the Final Reconciliation Disputes. The Parties shall instruct the Neutral Auditor to render its reasoned written decision, acting as an expert and not as an arbitrator, as soon as practicable but in no event later than sixty (60) days after its engagement

(which engagement shall be made no later than ten (10) Business Days after the end of the Resolution Period). Such decision shall be made on the basis of the accounting principles, procedures, policies and methods used by Sellers in preparing the Estimated Closing Net Working Capital and the Estimated Capital Expenditures, shall be set forth in a written statement delivered to Sellers and Buyer and shall be final, binding, conclusive and nonappealable for all purposes hereunder. Notwithstanding anything else contained herein, no Party may assert that any award issued by the Neutral Auditor is unenforceable because it has not been timely rendered. The term “Final Adjustment Statement” shall mean the definitive Adjustment Statement setting forth the final determination of the Closing Net Working Capital (the “Final Closing Net Working Capital”) and the Closing Capital Expenditures (the “Final Closing Capital Expenditures”) and resulting from (i) agreement by Sellers and Buyer during the Resolution Period or otherwise, (ii) a deemed acceptance pursuant to Section 2.5(b) or (iii) the determination by the Neutral Auditor in accordance with this Section 2.5(c).

(d) If the Final Closing Net Working Capital is greater than the Estimated Closing Net Working Capital, then Buyer shall pay to Sellers an amount equal to such excess in the manner set forth in Section 2.5(h). Conversely, if the Final Closing Net Working Capital is less than the Estimated Closing Net Working Capital, then Sellers shall pay to Buyer an amount equal to such difference in the manner set forth in Section 2.5(h).

(e) If the Final Closing Capital Expenditures is greater than the Estimated Capital Expenditures, then Buyer shall pay to Sellers an amount equal to such excess in the manner set forth in Section 2.5(h). Conversely, if the Final Closing Capital Expenditures is less than the Estimated Capital Expenditures, then Sellers shall pay to Buyer an amount equal to such difference in the manner set forth in Section 2.5(h).

(f) Buyer agrees that, following the Closing through the date that the Closing Net Working Capital and the Closing Capital Expenditures become final and binding pursuant to Section 2.5(c), it shall not (and shall cause its Affiliates not to) take any actions with respect to any accounting, books, records, principles, procedures, policies or methodologies on which the Closing Net Working Capital and the Closing Capital Expenditures are based that would impede or delay the determination of the Closing Net Working Capital or the Closing Capital Expenditures or the preparation of the written notice by Sellers specifying any Initial Reconciliation Disputes.

(g) Without limiting the provisions of Section 2.5(a) and the generality of Section 6.2, during the period of any dispute contemplated in this Section 2.5, Buyer shall, and shall cause its Affiliates to (i) provide Sellers and their Representatives with reasonable access to the relevant books and records, facilities and employees, its and its accountants’ work papers, schedules and other supporting data as may be reasonably requested by Sellers and (ii) otherwise cooperate in good faith with Sellers and their Representatives, including by providing on a timely basis all information necessary or useful in the determination of the Closing Net Working Capital and the Closing Capital Expenditures.

(h) Amounts owing by the Parties pursuant to Section 2.5(d) and Section 2.5(e) shall be aggregated or netted, as applicable, so that only one payment shall be made. Any payment required pursuant to Section 2.5(d), Section 2.5(e) and this Section 2.5(h)

shall be made by wire transfer of immediately available funds, in Dollars, to the account designated by Sellers or Buyer, as the case may be, within five (5) Business Days after the Final Adjustment Statement is determined by (i) agreement by Sellers and Buyer during the Resolution Period or otherwise, (ii) a deemed acceptance pursuant to Section 2.5(b) or (iii) the determination by the Neutral Auditor in accordance with Section 2.5(c). Payments due pursuant to this Section 2.5(h) shall be paid to the applicable Party together with interest on the amount owed at a rate of interest equal to LIBOR (determined, as applicable, on the Closing Date and at the end of each 30-day period thereafter) plus two (2%) thereon (such interest accruing for the period commencing on the Closing Date and continuing until the date of payment).

All requests for access to the properties, books, contracts, records and appropriate officers and employees of the Company and Sellers shall be made to such Representatives of Sellers as Sellers shall designate, who shall be solely responsible for coordinating all such requests and all

access permitted hereunder. It is further agreed that neither Buyer nor its Representatives shall contact any of the employees, customers, suppliers or Persons that have a business relationship with the Company in connection with the transactions contemplated hereby, whether in person or by telephone, mail or other means of communication, without the specific prior authorization of Sellers and without a Representative of the Company being present.

The foregoing indemnification obligation shall survive the Closing or termination of this Agreement. THE INDEMNIFICATION PROVISIONS IN THIS SECTION 6.2(B) SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING INDEMNIFICATION OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED UPON THE PERSON SEEKING INDEMNIFICATION OR ANY OTHER PERSON.

order or other similar remedy is not obtained, such Party shall, or shall cause its Affiliate or Representative to, furnish only that portion of such information that has been legally compelled, and shall, or shall cause its Affiliate or Representative to, exercise its reasonable best efforts to obtain assurance that confidential treatment will be accorded such disclosed information. Each of the Parties hereto shall instruct its Affiliates and Representatives having access to any information described in Section 6.3(c) or Section 6.3(d) of the obligation of confidentiality described in this Section 6.3 and shall be responsible for any breach of the terms of this Section 6.3 by any of its Affiliates or Representatives.

Notwithstanding the foregoing, none of Sellers or any of their Affiliates, nor Buyer nor any of its Affiliates, shall be obligated to make any payments or otherwise pay any consideration to any Person, to commence or participate in any Litigation or to offer or grant any accommodation to any Third Party in connection with any such consent, waiver, confirmation, novation or approval.

From the date of this Agreement until the Closing, each of Buyer and Sellers shall, and shall cause their respective Affiliates to (a) make or cause to be made the filings required of such Party or any of its Affiliates under any Laws with respect to the transactions contemplated by this Agreement, as promptly as is reasonably practicable, and in any event within five (5) Business Days after the date hereof, and to pay any fees due from it in connection with such filings, (b) cooperate with the other Parties and furnish all information in such Party’s possession that is necessary in connection with such other Party’s filings, (c) use reasonable best efforts to cause the expiration of the notice or waiting periods under the HSR Act and any other Laws with respect to the transactions contemplated by this Agreement as promptly as is reasonably practicable, (d) promptly inform the other Parties of any communication from or to, and any proposed understanding or agreement with, any Governmental Authority in respect of such filings, and permit the other Parties to review in advance any proposed communication by such Party to any Governmental Authority, (e) consult and cooperate with the other Parties in connection with any analyses, appearances, presentations, memoranda, briefs, arguments and opinions made or submitted by or on behalf of any Party in connection with all meetings, actions and proceedings with Governmental Authorities relating to such filings, (f) comply, as promptly as is reasonably practicable, with any requests received by such Party or any of its Affiliates under the HSR Act and any other Laws for additional information, documents or other materials,

Neither Party to this Agreement shall agree to participate in any meeting with any Governmental Authority in respect of any filings, investigation or other inquiry unless it consults with the other Party in advance and, to the extent permitted by such Governmental Authority, gives the other Party the opportunity to attend and participate at such meeting. Subject to the Confidentiality Agreement, the Parties will provide each other with copies of all correspondence, filings or communications between them or any of their representatives, on the one hand, and any Governmental Authority or members of its staff, on the other hand, with respect to this Agreement and the transactions contemplated hereby; provided, however, that Sellers may redact from any filings provided to Buyer hereunder, and shall not be required to provide any materials or information hereunder, to the extent such filings, materials or information relate to either Seller, individually, and not to the Company.

(a) After Closing, to the extent not prohibited by applicable Law, the Company shall continue to honor its obligations (as set forth in the Organizational Documents of the Company as of the date of this Agreement) with respect to the exculpation and indemnification of, and the advancement of expenses to, the Indemnified Officers and Directors with respect to any Third-Party Claims arising or resulting from any actions or omissions at or prior to the Closing (including the matters contemplated by this Agreement) by the Indemnified Officers and Directors, it being understood that the consummation of the transactions contemplated by this Agreement shall not modify such rights. The provisions of this Section 6.6 shall be in addition to, and not in substitution of, any and all releases under the Mutual Release.

(b) THE INDEMNIFICATION PROVIDED IN THE ORGANIZATIONAL DOCUMENTS OF THE COMPANY (AS OF THE DATE OF THIS

AGREEMENT) SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OF ANY PERSON SEEKING INDEMNIFICATION, OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED UPON SUCH PERSON SEEKING INDEMNIFICATION OR ANY OTHER PERSON.

(c) In the event the Company or any of its successors or assigns (i) consolidates or merges into any other Person and shall not be the continuing or surviving company or entity of such consolidation or merger or converts into any other Person or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in each such case, the Company shall cause proper provision to be made so that the successors and assigns of the Company shall assume the obligations set forth in this Section 6.6.

(d) The obligations of the Company under this Section 6.6 from and after the Closing Date shall not be terminated or modified in such a manner as to adversely affect any of the Indemnified Officers and Directors without the consent of such Person (it being expressly agreed that each of the Indemnified Officers and Directors is intended to be a third party beneficiary of this Section 6.6 with full rights of enforcement as if a party hereto). The rights of each Indemnified Officer and Director hereunder shall be in addition to any other rights the Indemnified Officers and Directors may have under the Organizational Documents of the Company, under any and all indemnification agreements of or entered into by the Company, or applicable Law (whether at law or in equity).

Section 6.7 Employee and Benefit Matters.

(a) Employment by Buyer. Buyer agrees that, should the Company or its successor-in-interest continue to employ the employees of Company as of the date of this Agreement, including any employees on authorized leave (each, an “Employee” and, collectively, the “Employees”), during the one-year period immediately following the Closing Date (the “Severance Period”), Buyer shall cause the Company or its successor-in-interest to do so with respect to each such Employee at a compensation level that is not less than the base pay for such Employee as of the date of this Agreement. Subject to Section 6.7(f), nothing in this Section 6.7 requires Buyer to employ or cause the Company or its successor-in-interest to employ an Employee from and after the Closing.

(b) Employee Benefits. Buyer shall offer employee benefits to the Employees on terms and conditions that are no less favorable in the aggregate to the Employees than those provided to similarly situated employees of Buyer. With the exception of the severance benefits provided for in Section 6.7(f), nothing herein shall be deemed to obligate Buyer to adopt or maintain any particular employee benefit plan (including any equity compensation plans or arrangements), and nothing in this Section 6.7 shall be deemed to limit the ability of the Company to amend or terminate any employee benefit plans, programs and policies of the Company (collectively, the “Company Benefit Plans”) at any time after the Closing Date. Sellers agree to cause the Company, prior to Closing, to adopt an amendment to the Company’s 401(k) plan terminating that plan effective immediately prior to, but conditioned upon, Closing.

(c) Credit for Prior Service. Buyer agrees that from and after the Closing Date, the Employees shall be credited with their length of service with the Company for purposes of eligibility and vesting (but not for purposes of benefit accrual) under all employee benefit plans, programs and policies of Buyer (collectively, the “Buyer Benefit Plans”) in which the Employees may be covered, to the same extent that service provided prior to the Closing Date by employees of Buyer is recognized under the relevant Buyer Benefit Plan. Such pre-Closing service credit shall also be taken into account for purposes of benefit computation under all vacation, sick leave, paid time off, and severance plans or policies that may apply to the Employees after the Closing Date. In addition, Buyer agrees to continue to recognize all vacation time, sick leave, paid time off, or other leave accrued by each Employee as of the Closing Date.

(d) Terms of Coverage. To the extent any Employees become covered under any Buyer Benefit Plan, any restriction on coverage for pre-existing conditions or requirement for evidence of insurability under such Buyer Benefit Plan shall be waived for such Employees. Buyer shall ensure that each Employee who becomes covered under any Buyer Benefit Plan that is a group health plan (including a “group health plan” as defined in Section 5000(b)(1) of the Code) shall receive credit for those sums paid in the current year under the corresponding Company Benefit Plan as deductibles, coinsurance and co-payments, towards any deductible and/or out-of-pocket maximum that may apply under such Buyer Benefit Plan.

(e) Performance Bonus. Notwithstanding anything to the contrary herein, Buyer acknowledges and agrees that the Company may, at any time prior to or at Closing and in its sole discretion, make 2010 performance bonus payments to Employees not exceeding $350,000 in the aggregate.

(f) Severance. If, during the Severance Period, either (i) Buyer terminates without Cause the employment of any Employee who was an Employee on the Closing Date or (ii) such an Employee resigns for Good Reason, then Buyer shall pay to such Employee severance benefits in a lump-sum amount equal to such Employee’s Severance Amount within thirty (30) days of such termination of employment or resignation. For purposes of this Section 6.7(f), a termination or resignation of employment shall occur if and when an Employee ceases, on what is reasonably expected to be a permanent basis, to provide, directly or indirectly, services to the Company and all of its Affiliates and successors in any capacity for compensation and such cessation constitutes a “separation from service” within the meaning of Section 409A(a)(2)(A)(i) of the Code. Additionally, the following terms shall have the following meanings:

(i) “Annual Base Salary” means the annual base salary of the Employee as of the date of this Agreement.

(ii) “Cause” means that the Employee (A) has engaged in gross negligence, gross incompetence or willful misconduct in the performance of his duties; (B) has failed to substantially perform the duties and services reasonably required by the Company and such failure continues for at least thirty (30) days after the Employee’s receipt of written notice of such failure from the Company; (C) has willfully engaged in conduct that is materially injurious to the Company or its Affiliates (monetarily or otherwise); (D) has committed an act of fraud, embezzlement or willful breach of a fiduciary duty to the Company (including the

unauthorized disclosure of confidential or proprietary material information of the Company); or (E) has been convicted of, pled guilty to, or pleaded no contest to, a crime involving fraud, dishonesty or moral turpitude.

(iii) “Good Reason” means the occurrence of any one or more of the following: (A) a material reduction in the nature or scope of the Employee’s authority or duties from those previously applicable to him; (B) a reduction in the Employee’s Annual Base Salary; (C) a diminution in the Employee’s eligibility to participate in any bonus, stock option, incentive award and other compensation plans in which the Employee was eligible to participate at the Closing Date; or (D) a change in the location of the Employee’s principal place of employment by the Company by more than sixty (60) miles from the location where he was principally employed; provided, however, that no such occurrence shall qualify as “Good Reason” if the Employee expressly consented in writing to any such occurrence prior to its occurrence.

(iv) “Severance Amount” means, with respect to a particular Employee, an amount equal to the Annual Base Salary minus the amount actually paid from and after the Closing Date to such Employee in respect of this Annual Base Salary.

Section 6.8 GO Zone Bonds. Sellers and Buyers agree as follows with respect to the GO Zone Bonds:

(a) Prior to Closing, Sellers shall cause the Company to provide such advance notices as may be required under the Credit Agreement to notify the Third-Party Lenders that (i) their commitments under the Credit Agreement will be terminated on the Closing Date and (ii) all “Borrowings” under the Credit Agreement will be repaid on the Closing Date;

(b) On the Closing Date, Buyer shall provide cash collateral in an amount equal to the GO Zone Bonds Amount (plus appropriate interest coverage) to SunTrust Bank, for the benefit of the issuers of the GO Zone Bonds Letters of Credit, in order to cause the GO Zone Bonds Letters of Credit to remain issued and outstanding and in favor of the Trustee under each GO Zone Indenture in the stated amount, in each case following the Closing Date;

(c) Sellers and Buyer shall work together to ensure that the consummation of the transactions contemplated by this Agreement will not (i) trigger a mandatory purchase under Article IV of the applicable GO Zone Indentures prior to Closing or (ii) cause a notice of mandatory purchase pursuant to the GO Zone Indentures to be delivered prior to Closing; and

(d) Sellers acknowledge that Buyer intends to trigger a mandatory purchase under Article IV of the applicable GO Zone Indentures following Closing. In consideration of the undertakings of Buyer under this Section 6.8, Sellers agree to reimburse Buyer for fifty percent (50%) of the excess of the sum of (i) any letter of credit fees incurred by Buyer under the GO Zone Bonds Letters of Credit, (ii) the amount of interest incurred under the GO Zone Bonds and (iii) any incremental fees (but, for the avoidance of doubt, excluding any remarketing fees) incurred by Buyer and paid to the issuing bank of the GO Zone Bonds Letters of Credit, over the amount of any interest earned by Buyer on the cash used to collateralize the GO Zone Bonds Letters of Credit pursuant to Section 6.8(b), in each case, to the extent such fees and interest are incurred or earned by Buyer (as applicable) during the period of time from the Closing Date

through the earlier to occur of (A) the date of such mandatory purchase and (B) the 45th day after Closing. Notwithstanding the foregoing, in no event shall Sellers’ reimbursement obligation hereunder exceed $450,000. Sellers shall pay Buyer the amount required to be reimbursed by Sellers pursuant to this Section 6.8(d) within five (5) Business Days of Buyer’s delivery to Sellers of an invoice therefore by wire transfer of immediately available funds, in Dollars, to the account(s) designated by Buyer.

Section 6.9 Waiver of Certain Rights. It is acknowledged that under the Company LLC Agreement there are certain rights of first offer, preemptive rights, rights of first refusal, options and similar rights and restrictions that apply in connection with the transfer of any Company Units. Solely in connection with the sale and transfer of the Company Units under this Agreement, each Seller (with regard to the proposed sale of Company Units by the other Seller and the conveyance of the Conveyed Lands pursuant to the Conveyed Lands Assignment Agreement) hereby waives any and all preferential purchase rights, preemptive rights, options, rights of first offer, tag-along rights or other rights, claims or restrictions with regard thereto, provided for under the Company LLC Agreement or otherwise. In the event the transactions under this Agreement are not closed and consummated, it is acknowledged that this waiver shall not apply with regard to any subsequent proposed sale or transfer of any of the Company Units by a Seller.

Section 6.10 Update Information. Prior to the Closing, each of Buyer and Sellers shall give the other Parties prompt written notice of any development that is reasonably likely to result in a failure of a condition to the Closing. At any time prior to the Closing, Sellers may correct and supplement in writing any information furnished on the Disclosure Schedules, or that would have been so furnished had it arisen prior to the date of this Agreement, by furnishing corrected or supplemented information to Buyer pursuant to the notice provisions hereof. Unless Buyer agrees otherwise in writing, any such corrections and supplements shall not amend the Disclosure Schedules or any representations, warranties or covenants of Sellers for any purpose under this Agreement.

Section 6.11 Books and Records. From and after the Closing, subject to the provisions of Article VII:

In addition, for a period of at least seven (7) years after the Closing Date, Buyer shall, and shall cause each of its Affiliates (including, after the Closing, the Company) to, preserve all original data room materials and other books, data, files, information and records relating to the Business or operations of the Company and existing as of the Closing Date and, thereafter, dispose of such

data room materials and other books, data, files, information and records only after it shall have given Sellers at least ninety (90) days’ prior written notice of such disposition and the opportunity, at their cost and expense, to remove and retain all or any part of such data room materials and other books, data, files, information and records as Sellers may select. Buyer shall afford to Sellers and their authorized Representatives reasonable access, during normal business hours, to such properties, books, contracts and records of the Business as remain in Buyer’s possession, as reasonably requested by Sellers; provided, however, that such access shall only be upon reasonable advance written notice and shall not disrupt personnel or operations of the Business and shall be at Sellers’ sole cost and expense. Buyer shall have the right to have a Representative present at all times during the exercise by Sellers of any of their access rights pursuant to this Section 6.11(b). Notwithstanding the foregoing, Sellers shall have no right of access to, and Buyer shall have no obligation to provide to Sellers, (i) information relating to any information the disclosure of which would jeopardize any privilege relating to such information available to the Company, Buyer or any Affiliate of Buyer or would cause the Company, Buyer or any Affiliate of Buyer to breach a confidentiality obligation; or (ii) any information the disclosure of which would result in a violation of Law. All requests for access to the properties, books, contracts, records and appropriate officers and employees of Buyer shall be made to such Representatives of Buyer as Buyer shall designate, who shall be solely responsible for coordinating all such requests and all access permitted hereunder. All requests for access to the properties, books, contracts, records and appropriate officers and employees of the Company shall be subject to the following additional limitations: (A) such access shall not violate any Law or contract to which Buyer or the Company is a party or otherwise expose Buyer or any of its Affiliates to a material risk of liability; (B) none of Sellers or their respective Representatives shall damage the assets and properties of the Company or any portion thereof and (C) each Seller shall use its commercially reasonable efforts to complete any on-site exercise of its access rights and all communications with any Person pursuant to this Section 6.11(b) in an expeditious and efficient manner.

THE INDEMNIFICATION PROVISIONS IN THIS SECTION 6.11(C) SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING INDEMNIFICATION OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED UPON THE PERSON SEEKING INDEMNIFICATION OR ANY OTHER PERSON.

Section 7.1 Tax Returns.

(a) Through the Closing, Sellers shall cause the Company to continue to be treated as a partnership for federal income tax purposes pursuant to Treasury Regulation Section ###-###-####-3(b)(1), and Sellers shall reflect the operations of the Company through the Closing Date on their federal income Tax Returns.

With respect to any other Tax Return of the Company covering a taxable

period ending on or before the Closing Date that is required to be filed after the Closing Date (an “Other Tax Return”), Sellers shall cause such Other Tax Return to be prepared, and shall cause to be included in such Other Tax Return all items required to be included therein. Not later than 30 days prior to the due date of each Other Tax Return, Sellers shall deliver a copy of such Other Tax Return to Buyer together with a statement of the difference, if any, between the amount of Tax shown as due on such Other Tax Return and the amount set up as a liability for such Tax in the Final Adjustment Statement. Sellers shall make all reasonable changes to such Other Tax Return requested by Buyer not later than 10 days prior to the due date of such Other Tax Return. If the Tax shown on the Other Tax Return exceeds the amount set up as a liability for such Tax in the Final Adjustment Statement, not later than the due date of such Other Tax Return, Sellers shall pay to Buyer the amount of such excess. If the amount set up as a liability for such Tax in the Final Adjustment Statement exceeds the Tax shown on the Other Tax Return, not later than the due date of such Other Tax Return, Buyer shall pay to Sellers the amount of such excess. Buyer shall cause the Company to file each Other Tax Return and timely pay the Taxes shown as due on each such Other Tax Return.

Buyer shall determine (by an interim closing of the books as of the Closing Date except for ad valorem Taxes, which shall be prorated on a daily basis based on the period beginning on the assessment date for ad valorem Taxes through the day before the next assessment date for such Taxes) the Tax that would have been due with respect to the period covered by such Tax Return if such taxable period ended on the Closing Date (the “Pre-Closing Tax”). Not later than 30 days prior to the due date of each such Tax Return, Buyer shall deliver a copy of such Tax Return to Sellers for their review. Buyer shall make all reasonable changes to such Tax Return requested by Sellers not later than 10 days prior to the due date of such Tax Return. If the Pre-Closing Tax included in the Tax shown on the Tax Return exceeds the amount set up as a liability for such Tax in the Final Adjustment Statement, not later than the due date of such Tax Return, Sellers shall pay to Buyer the amount of such excess. If the amount set up as a liability for such Tax in the Final Adjustment Statement exceeds the Pre-Closing Tax included in the Tax shown on the Tax Return, not later than the due date of such Tax Return, Buyer shall pay to Sellers the amount of such excess. Buyer shall cause the Company to file the Tax Return and timely pay the Taxes shown due on such Tax Return.

(d) Any Tax Return prepared pursuant to the provisions of this Section 7.1 shall be prepared in a manner consistent with practices followed in prior years with respect to similar Tax Returns, except as otherwise required by Law or fact.

(e) Buyer and Sellers shall cooperate fully, and Buyer shall cause the Company to cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of Tax Returns pursuant to this Section 7.1 and any audit, litigation or other proceeding (each, a “Tax Proceeding”) with respect to Taxes. Such cooperation shall include access to, the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such Tax Return or Tax Proceeding, and the making available of employees on a mutually convenient basis to provide

additional information and explanation of any material provided hereunder. Sellers will, and Buyer will and will cause the Company to, retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the later of 6 years after the Closing Date and the expiration of the applicable statute of limitations of the respective taxable periods, and to abide by all record retention agreements entered into with any Tax Authority. Buyer and Sellers each agree, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Tax Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated by this Agreement.

Section 7.2 Transfer Taxes. Buyer shall be responsible for and INDEMNIFY, DEFEND, AND HOLD HARMLESS Sellers for the payment of all state and local transfer, sales, use, stamp, registration or other similar Taxes, if any, resulting from the transactions contemplated by this Agreement. Buyer and Sellers shall cooperate in good faith to minimize, to the extent permissible under applicable Law, the amount of any such Taxes.

Section 7.3 Tax Indemnity.

(a) Subject (only in the case of any liability for non-income Taxes) to the applicable limitations of Section 9.4(c), Sellers shall be solely liable for, shall pay and shall INDEMNIFY, DEFEND, AND HOLD HARMLESS the Buyer Indemnified Parties and the Company from any and all Taxes attributable to any taxable period (or portion thereof as determined in accordance with the principles set forth in Section 7.1(c)) ending on or before the Closing Date in excess of any liability for Taxes reflected on the Final Adjustment Statement that relate to or result from the income, business, property or operations of the Company prior to and including the Closing Date. Buyer shall be solely liable for, shall pay, and shall INDEMNIFY, DEFEND, AND HOLD HARMLESS Sellers from any and all Taxes attributable to any taxable period (or portion thereof as determined in accordance with the principles set forth in Section 7.1(c)) beginning after the Closing Date that relate to or result from the income, business, property or operations of the Company after the Closing Date.

(b) If any claim (an “Indemnified Tax Claim”) is made by any Tax Authority that, if successful, would result in indemnification of any Party (the “Tax Indemnified Party”) by another Party (the “Tax Indemnifying Party”) under this Section 7.3, the Tax Indemnified Party shall promptly, but in no event later than the earlier of (i) fifteen (15) days after receipt of notice from the Tax Authority of such Indemnified Tax Claim and (ii) thirty (30) days prior to the date required for the filing of any protest of such Indemnified Tax Claim, notify the Tax Indemnifying Party in writing of such fact.

(c) The Tax Indemnifying Party shall control all decisions with respect to any Tax Proceeding involving an Indemnified Tax Claim and the Tax Indemnified Party shall take such action (including settlement with respect to such Tax Proceeding or the prosecution of such Tax Proceeding to a determination in a court or other tribunal of initial or appellate jurisdiction) in connection with a Tax Proceeding involving an Indemnified Tax Claim as the Tax Indemnifying Party shall reasonably request in writing from time to time, including the selection of counsel and experts and the execution of powers of attorney; provided, however, that (i) within 30 days after the notice required by Section 7.3(b) has been delivered (or such earlier

date that any payment of Taxes with respect to such Indemnified Tax Claim is due but in no event sooner than 5 days after the Tax Indemnifying Party’s receipt of such notice), the Tax Indemnifying Party requests that such Indemnified Tax Claim be contested, and (ii) if the Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the amount of the Indemnified Tax Claim and sue for a refund, the Tax Indemnifying Party shall have advanced to the Tax Indemnified Party, on an interest-free basis, the amount of such Indemnified Tax Claim. The Tax Indemnified Party shall not make any payment of an Indemnified Tax Claim for at least 30 days (or such shorter period as may be required by applicable Law) after the giving of the notice required by Section 7.3(b) with respect to such Indemnified Tax Claim, shall give to the Tax Indemnifying Party any information requested related to such Indemnified Tax Claim, and otherwise shall cooperate with the Tax Indemnifying Party in order to contest effectively any such Indemnified Tax Claim.

Notwithstanding anything to the contrary herein (but subject to the applicable provisions of Article IX), this Article VII shall be the exclusive remedy for any claims relating to Taxes (excluding any claims relating to representations and warranties (including Section 4.7)). The rights hereunder relating to (a) income Taxes shall survive the Closing until 30 days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter and (b) non-income Taxes shall survive the Closing for a period of 12 months after the Closing. No claim may be made or brought by any Party hereto after the expiration of the applicable survival period unless such claim has been asserted by written notice specifying the details supporting the claim on or prior to the expiration of the applicable survival period.

Section 7.5 Purchase Price Allocation. The Parties agree that the transactions contemplated hereby will be treated for federal income Tax purposes as a sale of interests in the Company by Sellers and as a purchase of the assets of the Company by Buyer. Buyer shall prepare an allocation of the Purchase Price and assumed obligations among the purchased assets that complies with Section 1060 of the Code and the Treasury regulations promulgated thereunder (the “Allocation”). Buyer shall provide such Allocation to Sellers within ninety (90) days from the Closing Date, and Sellers shall have thirty (30) days after receipt thereof to provide Buyer with any written objection thereto. Buyer shall use commercially reasonable efforts to update the Allocation in a manner consistent with Section 1060 of the Code following any adjustments to the Purchase Price pursuant to this Agreement. Sellers and Buyer shall report consistently with the Allocation in all tax returns, including IRS Form 8594, which Buyer shall timely file with the IRS, and neither Sellers nor Buyer shall take any position in any return that is inconsistent with the Allocation, as adjusted, in each case, unless required to do so by a final determination as defined in Section 1313 of the Code.

If a written notice of claim has been timely given in accordance with this Agreement prior to the expiration of any applicable survival period for such representation, warranty, covenant or agreement, then the applicable representation, warranty, covenant or agreement shall survive as to such claim, until such claim has been finally resolved.

Section 9.2 Indemnification.

(a) Subject to the provisions of this Article IX, from and after the Closing, each of Sellers (individually and neither jointly nor severally), shall indemnify and hold harmless Buyer, Buyer’s Affiliates (which includes, for the avoidance of doubt, the Company from and after the Closing) and their respective Representatives (the “Buyer Indemnified Parties”) from and against all Losses that the Buyer Indemnified Parties incur arising from or out of any breach of (i) any representation or warranty of such Seller in this Agreement (or contained in any certificate delivered in connection herewith) or (ii) any covenant of such Seller in this Agreement (or contained in any certificate delivered in connection herewith).

(b) Subject to the provisions of this Article IX, from and after the Closing, Buyer shall indemnify and hold harmless Sellers and their respective Affiliates and Representatives (the “Seller Indemnified Parties”) from and against all Losses that the Seller Indemnified Parties incur arising from or out of any breach of any representation, warranty or covenant of Buyer in this Agreement (or in any certificate delivered in connection herewith).

(c) THE INDEMNIFICATION PROVISIONS IN THIS SECTION 9.2 SHALL BE ENFORCEABLE REGARDLESS OF WHETHER ANY PERSON (INCLUDING THE PERSON FROM WHOM INDEMNIFICATION IS SOUGHT) ALLEGES OR PROVES THE SOLE, CONCURRENT, CONTRIBUTORY OR COMPARATIVE NEGLIGENCE OF THE PERSON SEEKING INDEMNIFICATION OR THE SOLE OR CONCURRENT STRICT LIABILITY IMPOSED UPON THE PERSON SEEKING INDEMNIFICATION OR ANY OTHER PERSON.

(d) Notwithstanding anything to the contrary herein, the Parties shall have a duty to use commercially reasonable efforts to mitigate any Losses arising out of or relating to this Agreement or the transactions contemplated hereby.

(e) Notwithstanding anything in this Article IX to the contrary, all Losses relating to Taxes (other than arising out of or relating to any breach of any representations and warranties (including Section 4.7) relating to Taxes) shall only be subject to indemnification under Section 7.3.

(f) The Parties have agreed upon a threshold (as provided in Section 9.4(a)) in the amount of $250,000 and a deductible (as provided in Section 9.4(b)) in an amount equal to one percent (1%) of the Base Purchase Price as a means of applying a materiality standard to the amount of any post-Closing claim that any Buyer Indemnified Party may have against Sellers resulting from a breach of a representation or warranty by Sellers. Therefore, for purposes of (i) applying the post-closing indemnification remedies provided in this Article IX, (ii) determining whether any breach of a representation or warranty of Sellers has occurred and (iii) calculating the amount any Losses relating thereto, Sellers’ representations and warranties shall be considered and applied without regard to any reference as to materiality, materially, material respects, Material Adverse Effect or similar materiality qualifiers set forth therein; provided, however, that this Section 9.2(f) shall in no respect modify the other provisions of this Agreement for purposes of determining whether any conditions to Closing have been satisfied.

(g) Subject to the provisions of this Article IX, from and after the Closing, the Company shall indemnify and hold harmless the Seller Indemnified Parties from and against all Losses that the Seller Indemnified Parties incur arising from or out of (i) the Business, the Company or the Conveyed Lands; or (ii) otherwise relating to the Company Units, in each case whether attributable or related to periods prior to, on or after the Closing Date.

Section 9.3 Indemnification Procedures. Claims for indemnification under this Agreement (other than claims involving a Tax Proceeding, the procedures for which are set forth in Section 7.3) shall be asserted and resolved as follows:

(a) Any Buyer Indemnified Party or Seller Indemnified Party claiming indemnification under this Agreement (an “Indemnified Party”) with respect to any claim asserted against the Indemnified Party by a Third Party (a “Third-Party Claim”) in respect of any matter that is subject to indemnification under Section 9.2 shall promptly (i) notify the other Party (the “Indemnifying Party”) of the Third-Party Claim and (ii) transmit to the Indemnifying Party a written notice (a “Claim Notice”) describing in reasonable detail the nature of the Third-Party Claim, a copy of all papers served with respect to such Third-Party Claim (if any), the Indemnified Party’s best estimate of the amount of Losses attributable to the Third-Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

(b) The Indemnifying Party shall have the right to control the defense of the Indemnified Party against such Third-Party Claim. If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third-Party Claim (such election to be without prejudice to the right of the Indemnifying Party to dispute whether such claim is for indemnifiable Losses under this Article IX), then the Indemnifying Party shall have the right to defend such Third-Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying Party in accordance with this Section 9.3(b). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that the Indemnifying Party shall not enter into any settlement agreement without the

written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided, further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the Third Party asserting the Third-Party Claim to all Indemnified Parties affected by the Third-Party Claim, and (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by the Indemnified Party or its Affiliates. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third-Party Claim that the Indemnifying Party elects to contest, including the making of any related counterclaim against the Person asserting the Third-Party Claim or any cross complaint against any Person. The Indemnified Party may otherwise participate in, but not control, any defense or settlement of any Third-Party Claim controlled by the Indemnifying Party pursuant to this Section 9.3(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c) If the Indemnifying Party does not notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 9.3(b), then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable costs and expenses (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third-Party Claim with counsel selected by the Indemnified Party (who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third-Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third-Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 9.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d) Subject to the other provisions of this Article IX, in the event that an Indemnified Party determines that it has a claim for indemnifiable Losses against an Indemnifying Party(ies) hereunder (other than as a result of a Third Party Claim), the Indemnified Party shall give written notice thereof to the Indemnifying Party(ies), specifying, in reasonable detail, the amount of such claim, the nature and basis of the alleged breach or act giving rise to such claim and all relevant facts and circumstances relating thereto. The Indemnified Party shall provide the Indemnifying Party(ies) with full access to its books and records (and, if Seller(s) are the Indemnifying Party(ies), the Company’s books and records) during normal business hours for the purpose of allowing the Indemnifying Party(ies) a reasonable opportunity to verify any such claim for indemnifiable Losses. The Indemnifying Party(ies) shall notify the Indemnified Party within forty-five (45) days following its receipt of such notice and granting of such access if the Indemnifying Party(ies) disputes its liability to the Indemnified Party under this Article IX. If the Indemnifying Party(ies) does not so notify the Indemnified Party, the claim specified by the Indemnified Party in such notice shall be a liability of the applicable Indemnifying Party(ies) under this Article IX, and the Indemnifying Party(ies) shall either (i) pay the amount of such claim to the Indemnified Party on demand or, in the case of any notice in which the amount of the claim (or any portion of the claim) is estimated, on such later date when the amount of such claim (or such portion of such claim) becomes finally

determined, or (ii) if the Indemnifying Party(ies) is one or more of the Sellers, instruct the Escrow Agent in writing to release to Buyer the amount of such indemnifiable Losses from the escrowed funds. If the Indemnifying Party(ies) has timely disputed its liability with respect to such claim as provided above, the Indemnifying Party(ies) and the Indemnified Party shall negotiate in good faith to resolve such dispute. Promptly following the final determination of the amount of indemnifiable Losses to which the Indemnified Party is entitled (whether determined in accordance with this Section 9.3(d) or by a court of competent jurisdiction), the Indemnifying Party(ies) shall either (A) pay such indemnifiable Losses to the Indemnified Party by wire transfer or certified check made payable to the order of the Indemnified Party, or (B) if the Indemnifying Party(ies) is one or more of the Sellers, instruct the Escrow Agent in writing to release to Buyer the amount of such indemnifiable Losses from the escrowed funds.

(e) Subject to the limitations on Sellers’ liability set forth in this Agreement:

(i) Each Seller shall be individually liable for Losses resulting from its breach of (A) its representations and warranties in Article III (or in any certificate delivered in connection herewith, to the extent relating to such Seller’s representations and warranties in Article III) or (B) its covenant in Section 6.16; and

(ii) SGR and SPE shall be liable (individually and neither jointly nor severally), for 60% and 40%, respectively, of any Losses resulting from a breach of (A) the representations and warranties in Article IV (or in any certificate delivered in connection herewith, to the extent relating to the representations and warranties in Article IV) or (B) Sellers’ covenants set forth herein (other than the covenants set forth in Section 6.16).

(f) In the event an Indemnified Party shall recover Losses in respect of a claim of indemnification under this Article IX, no other Indemnified Party shall be entitled to recover the same Losses in respect of a claim for indemnification.

(g) In no event shall the amount of Losses deemed to be incurred by Buyer hereunder in respect of any matter involving the condition of the Facility or its operation in compliance with applicable Laws exceed the amount that would be incurred in implementing the Lowest Cost Response.

Section 9.4 Limitations on Liability of Sellers. Notwithstanding anything to the contrary stated in this Agreement:

(a) a breach of any representation or warranty of Sellers in this Agreement (or in any certificate delivered in connection with this Agreement), subject to the provisions of Section 9.1, in connection with any single item or group of related items that results in Losses of less than $250,000 shall be deemed, for all purposes of this Article IX not to be a breach of such representation or warranty; provided, however, that the limitation set forth in this Section 9.4(a) shall not apply to Losses arising from a breach of Sellers’ representations and warranties contained in Sections 3.1, 3.2, 3.6, 4.3(a), and, solely with respect to Taxes resulting from the income of the Company, Section 4.7 (or in any certificate delivered in connection herewith, to the extent relating to Sellers’ representations and warranties contained in Sections 3.1, 3.2, 3.6, 4.3(a), and, solely with respect to Taxes resulting from the income of the Company, Section 4.7);

(b) Sellers shall have no liability arising out of or relating to Section 9.2(a)(i) except if the aggregate Losses actually incurred by the Buyer Indemnified Parties thereunder exceed one percent (1%) of the Base Purchase Price (and then, subject to Section 9.4(c), only to the extent such aggregate Losses exceed such amount); provided, however, that the limitation set forth in this Section 9.4(b) shall not apply to Losses arising from a breach of Sellers’ representations and warranties contained in Sections 3.1, 3.2, 3.6, 4.3(a), and, solely with respect to Taxes resulting from the income of the Company, Section 4.7 (or in any certificate delivered in connection herewith, to the extent relating to Sellers’ representations and warranties contained in Sections 3.1, 3.2, 3.6, 4.3(a), and, solely with respect to Taxes resulting from the income of the Company, Section 4.7);

(c) in no event shall Sellers’ aggregate liability arising out of or relating to Sections 9.2(a)(i), 9.2(a)(ii) (only with respect to a breach of Sellers’ indemnity obligation under Section 7.3(a) with respect to non-income Taxes) or Section 10.2 exceed five percent (5%) of the Base Purchase Price; provided, however, that only with respect to Section 3.1, Section 3.2, Section 3.6, Section 4.3(a) and, solely with respect to Taxes resulting from the income of the Company, Section 4.7, and any liability arising under Section 9.2(a)(ii) with respect to a breach of Seller’s indemnity obligation under Section 7.3(a) with respect to income Taxes, each Seller shall be individually liable for Losses arising from its breach in an amount not to exceed 60% of the Base Purchase Price in the case of SGR and 40% of the Base Purchase Price in the case of SPE;

(d) no Buyer Indemnified Party shall be entitled to indemnification under Section 9.2(a) to the extent Buyer has otherwise been compensated by reasons of adjustments (pursuant to Section 2.5) in the calculation of the Purchase Price relative to what it would have been absent such Losses; and

(e) the amount of any Losses subject to indemnification under this Article IX shall be reduced or reimbursed, as the case may be, by any Third Party insurance proceeds, recoveries, or available net Tax Benefits received or realized by the relevant Buyer Indemnified Party or Seller Indemnified Party, as applicable with respect to such Losses. Buyer and Seller shall, and shall cause the Buyer Indemnified Parties and Seller Indemnified Parties, as applicable, to, use commercially reasonable efforts to collect any amounts available under such Third Party insurance coverage and from any Person alleged to have responsibility and to realize any available net Tax Benefits. If a Buyer Indemnified Party or Seller Indemnified Party, as applicable, receives an amount under Third Party insurance coverage or from a Third Party or realizes any net Tax Benefit with respect to Losses that were the subject of indemnification under this Article IX (or under Article VII) at any time subsequent to indemnification provided hereunder, then such Buyer Indemnified Party or Seller Indemnified Party, as applicable, shall promptly reimburse Sellers to the extent of the amount received.

Section 9.5 Waiver of Other Representations.

(a) NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO, AND THE PARTIES HEREBY AGREE, THAT NONE OF SELLERS, OR ANY OF THEIR AFFILIATES OR REPRESENTATIVES, HAS MADE OR IS MAKING ANY REPRESENTATION OR

Section 9.7 Exclusive Remedy; No Consequential Damages.

Furthermore, at any time on or before the Final Escrow Release Date, Buyer’s sole and exclusive remedy regarding indemnification for Losses (other than Losses attributable to (i) Sellers’ breach of (A) representations and warranties in Section 3.1, Section 3.2, Section 3.6, Section 4.3 and, solely with respect to Taxes resulting from the income of the Company, Section 4.7 (or in any certificate delivered in connection herewith, to the extent relating to Sellers’ representations and warranties contained in Sections 3.1, 3.2, 3.6, 4.3(a), and, solely with respect to Taxes resulting

from the income of the Company, Section 4.7), or (B) any covenant of Sellers set forth herein (or in any certificate delivered in connection herewith) or (ii) any claim for indemnity under Section 7.3 relating to income Taxes) shall be to enforce its remedies under Section 9.9. Except with respect to claims identified above in this Section 9.7(a), and to the extent allowed by applicable Law, each Party hereby waives, releases, acquits and forever discharges the other Parties and their respective Affiliates and Representatives from any and all claims, actions, causes of action, demands, rights, damages, costs, expenses, Losses or compensation whatsoever, whether direct or indirect, known or unknown, foreseen or unforeseen, that such Party now (or at Closing) has against the other Party or Parties and their respective Affiliates and Representatives with respect to the transactions contemplated by this Agreement.

(b) NO PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES, LOST PROFITS OR LOST BENEFITS, LOSS OF ENTERPRISE VALUE, DIMINUTION IN VALUE OF THE BUSINESS, DAMAGES TO REPUTATION OR LOSS TO GOODWILL, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM ANY OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT; PROVIDED, HOWEVER, THIS SECTION 9.7(B) SHALL NOT LIMIT A PARTY’S RIGHT TO RECOVERY UNDER ARTICLE IX FOR ANY SUCH DAMAGES TO THE EXTENT SUCH PARTY IS REQUIRED TO PAY SUCH DAMAGES TO A THIRD PARTY IN CONNECTION WITH A MATTER FOR WHICH SUCH PARTY IS OTHERWISE ENTITLED TO INDEMNIFICATION UNDER ARTICLE IX; AND PROVIDED FURTHER THAT NOTWITHSTANDING THE WAIVER AND RELEASE BY THE COMPANY UNDER THE MUTUAL RELEASE OR THE LIMITATIONS SET FORTH ABOVE, THE COMPANY DOES NOT WAIVE OR RELEASE, AND EACH OF THE BUYER INDEMNIFIED PARTIES SHALL HAVE THE RIGHT TO RECOVER UNDER ARTICLE IX, ANY ACTUAL LOSSES (INCLUDING LOST REVENUES SOLELY WITH RESPECT TO THE CONTRACTS SET FORTH ON SCHEDULE 9.7(B)) SUFFERED BY THE COMPANY AS A DIRECT RESULT OF ANY BREACH BY SELLERS OF ANY REPRESENTATION, WARRANTY OR COVENANT HEREUNDER (OR IN ANY CERTIFICATE DELIVERED IN CONNECTION HEREWITH).

Section 9.8 Release of Claims. Upon the Closing, the Company, the Sellers and each of the individuals listed on Schedule 1.1(b) shall execute and deliver a release, in substantially the form attached hereto as Exhibit C (the “Mutual Release”).

Section 9.9 Escrow Release.

(a) If Sellers are obligated to make payment of any amounts pursuant to this Article IX and such obligation is not in dispute, then Buyer and Sellers shall, within three (3) Business Days of such obligation arising (or, if later, ceasing to be in dispute), issue joint written instructions to the Escrow Agent instructing the Escrow Agent to remit the amount of such obligation to the account of Buyer (up to a maximum amount equal to the Escrow Amount) by wire transfer of immediately available funds within three (3) Business Days of the Escrow Agent’s receipt of such joint written instruction. If the amount of such obligation exceeds the Escrow Amount, the joint written instructions issued pursuant to this Section 9.9(a) shall require

the release of the entire Escrow Amount and Buyer shall notify Sellers of the remaining amount required to be funded by Sellers.

(b) On the date falling six (6) months after the Closing Date (or, if such date is not a Business Day, on the Business Day immediately preceding such date) (the “Initial Escrow Release Date”), Buyer and Sellers shall (subject to Section 9.9(c) and unless the Escrow Amount is or would be, pursuant to Section 9.9(c), zero) issue joint written instructions to the Escrow Agent instructing the Escrow Agent to release from the Escrow Agreement and remit to the account of Sellers by wire transfer of immediately available funds within three (3) Business Days of the Escrow Agent’s receipt of such joint written instruction an amount equal to fifty percent (50%) of the Escrow Amount less any amounts previously released from the Escrow Agreement or held under the Escrow Agreement in respect of pending claims. On the date falling twelve (12) months after the Closing Date (or, if such date is not a Business Day, on the Business Day immediately preceding such date) (the “Final Escrow Release Date”), Buyer and Sellers shall (subject to Section 9.9(c) and unless the Escrow Amount is or would be, pursuant to Section 9.9(c), zero) issue joint written instructions to the Escrow Agent instructing the Escrow Agent to remit the entirety of the balance of the Escrow Amount to the account of Sellers by wire transfer of immediately available funds within three Business Days of receipt of such joint written instruction.

(c) If, on an Escrow Release Date, there are any pending unresolved claims by a Buyer Indemnified Party under this Article IX (or under Section 7.3 with respect to Sellers’ indemnity obligation under Section 7.3(a) with respect to Taxes), the amount that otherwise would be included in the joint instruction issued by Buyer and Sellers pursuant to Section 9.9(b) shall be reduced by an amount equal to such claims (to the extent that such reduction does not reduce the Escrow Amount below fifty percent (50%) with respect to the Initial Escrow Release Date or zero with respect to the Final Escrow Release Date). Such amount of reduction in respect of a pending unresolved claim by a Buyer Indemnified Party under this Article IX (or, under Section 7.3 with respect to Sellers’ indemnity obligations under Section 7.3(a) with respect to Taxes) shall be retained in the Escrow Account until such pending unresolved claim is resolved. Within three Business Days of such resolution, Buyer and Sellers shall issue joint written instructions to the Escrow Agent instructing the Escrow Agent to remit the amount relating to that resolved matter to the account of Buyer or Sellers, according to such resolution, by wire transfer of immediately available funds within three (3) Business Days of the Escrow Agent’s receipt of such joint written instruction.

(d) In addition to the releases from the Escrow Agreement provided in above in this Section 9.9, upon the termination of the Escrow Agreement in accordance with the terms and provisions thereof, Buyer and Sellers shall issue joint written instructions to the Escrow Agent instructing the Escrow Agent to release the total amount of interest earned on the Escrow Amount from the Escrow Agreement and remit the same to the account of Sellers by wire transfer of immediately available funds within three (3) Business Days of the Escrow Agent’s receipt of such joint written instruction.

ARTICLE X.
TERMINATION

Section 10.1 Termination. Prior to the Closing, this Agreement may be terminated and the transactions contemplated hereby abandoned:

(a) by the mutual consent of Buyer and Sellers as evidenced in a writing signed by each of Buyer and Sellers;

(b) by Buyer (provided it is not then in material breach of any of its obligations under this Agreement), if there has been a material breach by Sellers of any representation, warranty or covenant contained in this Agreement (i) such that the conditions set forth in Section 8.2 would not be satisfied as of the time of such termination and (ii) such breach is incapable of being cured or has not been cured by Sellers within thirty (30) days after written notice thereof from Buyer;

(c) by Sellers (provided neither Seller is then in material breach of any of its obligations under this Agreement), if there has been a material breach by Buyer of any representation, warranty or covenant contained in this Agreement (i) such that the conditions set forth in Section 8.3 would not be satisfied as of the time of such termination and (ii) such breach is incapable of being cured or has not been cured by Buyer within thirty (30) days after written notice thereof from Sellers;

(d) by either Buyer or Sellers if any Governmental Authority having competent jurisdiction has issued a final and non-appealable order, decree, ruling or injunction (other than a temporary restraining order) or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement;

(e) by either Buyer or Sellers, if the Closing has not occurred on or before April 15, 2011 (the “Outside Date”) or such later date as the Parties may agree upon; provided, however, that the Outside Date may be extended for a period not to exceed sixty (60) days by either Buyer or Sellers by written notice to the other Party or Parties if the transactions contemplated by this Agreement shall not have been consummated as a result of the conditions set forth in Section 8.1(b) failing to have been satisfied and the Party or Parties requesting such extension reasonably believe(s) that the relevant approvals will be obtained during such extension period; provided, further, that the right to terminate this Agreement under this Section 10.1(e) shall not be available to any Party whose failure to fulfill any obligation under this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to the Outside Date; or

(f) by Sellers, upon an uncured breach by Buyer of the covenant set forth in Section 2.1(b).

Section 10.2 Effect of Termination. In the event of termination and abandonment of this Agreement pursuant to Section 10.1, this Agreement shall forthwith become null and void and have no effect, and the obligations of the Parties under this Agreement shall terminate, except for the obligations set forth in Section 2.1(b), this Section 10.2, Section 11.2 and Section 11.4, each of which shall survive termination of this Agreement; provided, however, that

if this Agreement is validly terminated by a Party as a result of a material breach of this Agreement by the non-terminating Party, then, subject to the limitations set forth in Section 9.3(e), and Section 9.4(e), the terminating Party shall be entitled to all rights and remedies available at law or in equity, and the consequences of such termination shall include remedies in respect of the Deposit as set forth in this Section 10.2. In the event this Agreement is terminated under Section 10.1(c), then in such event the Parties shall jointly instruct the Escrow Agent in writing to pay the Deposit (together with any interest earned thereon) to Sellers as liquidated damages. The Parties agree that the actual damages sustained by Sellers in the event of a termination of this Agreement pursuant to Section 10.1(c) are difficult to ascertain with any certainty, that the Deposit is a reasonable estimate of such damages, and that such payment shall be considered as liquidated damages and not a penalty. In the event this Agreement is terminated for any reason other than pursuant to Section 10.1(c), the Parties shall jointly instruct the Escrow Agent in writing to pay the Deposit (together with any interest earned thereon) to Buyer. No termination of this Agreement shall affect the obligations of the parties contained in the Confidentiality Agreement, all of which obligations shall survive termination of this Agreement in accordance with their terms.

Section 11.2 Assignment. No Party shall assign this Agreement or any part hereof, by operation of law or otherwise, without the prior written consent of the other Parties. Any attempted assignment in violation of this Section 11.2 shall be void. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns.

Section 11.3 Rights of Third Parties. Except for the provisions of Section 6.2, Section 6.6 and Article IX that are intended to be enforceable by the Persons respectively referred to therein, nothing expressed or implied in this Agreement is intended or shall be construed to confer upon or give any Person, other than the Parties and their permitted successors and assigns, any legal or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 11.4 Expenses. Except as otherwise provided herein, each Party shall bear its own expenses incurred in connection with this Agreement and the transactions contemplated hereby whether or not such transactions shall be consummated, including all fees of its legal counsel, financial advisors and accountants.

Section 11.5 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Any facsimile or electronic copies hereof or signatures hereon shall, for all purposes, be deemed originals.

Section 11.6 Entire Agreement. This Agreement (together with the Disclosure Schedules and exhibits to this Agreement) and the Confidentiality Agreement constitute the entire agreement among the Parties and supersede any other agreements, whether written or oral, that may have been made or entered into by or among any of the Parties or any of their respective Affiliates relating to the transactions contemplated hereby. No representations, warranties, covenants, understandings or agreements, oral or otherwise, relating to the transactions contemplated by this Agreement exist between Buyer, on the one hand, and either Seller or its Affiliates, on the other hand, except as expressly set forth in this Agreement, in any certificate delivered at Closing and in any of the other Transaction Documents.

Section 11.7 Disclosure Schedules. Unless the context otherwise requires, all capitalized terms used in the Disclosure Schedules shall have the respective meanings assigned to such terms in this Agreement. No reference to or disclosure of any item or other matter in the Disclosure Schedules shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedules. No disclosure in the Disclosure Schedules relating to any possible breach or violation of any agreement or Law shall be construed as an admission or indication that any

such breach or violation exists or has actually occurred. The inclusion of any information in the Disclosure Schedules shall not be deemed to be an admission or acknowledgment by Sellers that in and of itself, such information is material to or outside the ordinary course of the business of the Company or is required to be disclosed on the Disclosure Schedules. Each numbered Schedule in the Disclosure Schedules qualifies only the correspondingly numbered representation, warranty or covenant to the extent specified therein and such other representations, warranties or covenants to the extent a matter in such numbered Schedule is disclosed in such a way as to make its relevance to such other representation, warranty or covenant reasonably apparent.

Section 11.8 Amendments. This Agreement may be amended or supplemented at any time by additional written agreements signed by each Party, as may mutually be determined by the Parties to be necessary, desirable or expedient to further the purpose of this Agreement or to clarify the intention of the Parties.

Section 11.9 Publicity. No Party or any Affiliate or Representative of such Party shall issue or cause the publication of any press release or public announcement or otherwise communicate with any news media in respect of this Agreement or the transactions contemplated hereby without the prior written consent of the other Party (which consent shall not be unreasonably withheld, conditioned or delayed), except as may be required by Law or applicable securities exchange rules and except with respect to customary investor and analyst presentations, meetings and conference calls, in which case, the Party issuing or publishing such press release or making such public announcement shall provide, to the extent reasonably practicable, the other Party with a copy of such press release or public announcement (including any slides or transcripts to be used in any investor or analyst presentation or conference) in advance of its issuing or publishing such press release or making such public announcement, as applicable.

Section 11.10 Severability. If any term or other provision of this Agreement is illegal, invalid or unenforceable under any Law or as a matter of 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 by this Agreement is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision contained herein is, to any extent, invalid or unenforceable in any respect under the Laws governing this Agreement, the Parties to this Agreement shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the greatest extent possible.

Section 11.11 Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in the Court of Chancery of the State of Delaware, this being in addition to any other remedy to which such Party is entitled at law or in equity or pursuant to the terms of this Agreement.

Section 11.12 Governing Law; Jurisdiction.

(a) This Agreement shall be governed by and construed in accordance with the Laws of the State of Delaware (without regard to the conflict of laws principles thereof). Each of the Parties irrevocably agrees that any legal action or proceeding with respect to this Agreement or the transactions contemplated hereby shall be brought and determined in any state or federal court in Delaware, and each of the Parties hereto irrevocably submits to the jurisdiction of such courts solely in respect of any legal proceeding arising out of or related to this Agreement. The Parties further agree that the Parties shall not bring suit with respect to any disputes arising out of this Agreement or the transactions contemplated hereby in any court or jurisdiction other than the above specified courts; provided, however, that the foregoing shall not limit the rights of the Parties to obtain execution of judgment in any other jurisdiction. The Parties further agree, to the extent permitted by Law, that a final and unappealable judgment against a Party in any action or proceeding contemplated above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified copy of which shall be conclusive evidence of the fact and amount of such judgment. Except to the extent that a different determination or finding is mandated due to the applicable Law being that of a different jurisdiction, the Parties agree that all judicial determinations or findings by a state or federal court in Delaware with respect to any matter under this Agreement shall be binding.

(b) To the extent that any Party hereto has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each such Party hereby irrevocably (i) waives such immunity in respect of its obligations with respect to this Agreement and (ii) submits to the personal jurisdiction of any court described in Section 11.12(a).

(c) THE PARTIES HERETO AGREE THAT THEY HEREBY IRREVOCABLY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION TO ENFORCE OR INTERPRET THE PROVISIONS OF THIS AGREEMENT.

Section 11.13 Time. Time is of the essence in the performance of each and every term, condition, and covenant contained in this Agreement.

Section 11.14 Joinder of PAA and the Company.

(a) As an inducement to Sellers to enter into this Agreement, PAA, joins herein for the sole purpose of agreeing to indemnify and hold harmless the Seller Indemnified Parties from and against all Losses that the Seller Indemnified Parties incur arising from or out of a breach by Buyer of its obligations under Section 2.3(c)(ii), Section 2.3(c)(iii), Section 2.3(c)(iv) and Section 2.3(c)(v). PAA’s indemnity under this Section 11.14(a) shall in no way be affected, modified or diminished by reason of any amendment, modification, waiver of, or change in any of the terms, conditions, representations, warranties, covenants and other agreements in this Agreement. The obligations of PAA under this Section 11.14(a) are independent of those of Buyer under this Agreement, and a separate action or actions may be brought or prosecuted against PAA to enforce its obligations under this Section 11.14(a),

irrespective of whether any action is brought against Buyer or whether Buyer is joined in any such action or actions. If Closing occurs and Buyer’s obligations under Section 2.3(c)(ii), Section 2.3(c)(iii), Section 2.3(c)(iv) and Section 2.3(c)(v) have been fully performed, the obligations of PAA under this Section 11.14(a) shall terminate.

(b) As an inducement to the Parties to enter into this Agreement, the Company joins herein for the sole purpose of being bound by the provisions set forth in Sections 6.6 and 9.2(g).
