AGREEMENT:

NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein, Sellers, the Company and Buyer do hereby agree as follows:

ARTICLE I
TERMS OF THE TRANSACTION

Section 1.1 Agreement to Purchase and Sell Interests. Sellers agree to sell and Buyer agrees to purchase, for the consideration hereinafter set forth and subject to the terms and provisions herein, the Interests.

EXECUTION COPY

Section 1.2 Purchase Price.

In consideration of the sale of the Interests to Buyer, Buyer will pay to Sellers an aggregate cash purchase price of two hundred sixty-six million Dollars ($266,000,000) (the “Purchase Price”), subject to adjustment as provided in Section 1.3. The Purchase Price, as adjusted pursuant to Section 1.3, is the “Adjusted Purchase Price.”

Section 1.3 Potential Adjustments to the Purchase Price

(a) The Purchase Price paid on the Closing Date will be:

(i) increased by the positive amount, if any, of the aggregate amount by which the Estimated Closing Working Capital exceeds seven million Dollars ($7,000,000) (the “Target Working Capital”);

(ii) decreased by the negative amount, if any, of the aggregate amount by which the Estimated Closing Working Capital is less than the Target Working Capital;

(iii) in the event that between the date of this Agreement and the earlier of the Closing Date and October 31, 2009, the Company fails to make capital expenditures in the amounts and for the projects set forth in the Capital Expenditure Plan (as defined in Section 7.1) with respect to such period, decreased by the amount by which such actual capital expenditures for the projects set forth in the Capital Expenditure Plan are less than the amounts set forth in the Capital Expenditure Plan with respect to such period;

(iv) in the event that between the date of this Agreement and the earlier of the Closing Date and October 31, 2009, the Company makes capital expenditures in excess of the amounts and for the projects set forth in the Capital Expenditure Plan with respect to such period, increased by the amount by which such actual capital expenditures for the projects set forth in the Capital Expenditure Plan are more than the amounts set forth in the Capital Expenditure Plan with respect to such period;

(v) in the event that the Closing Date is after October 31, 2009, and between November 1, 2009 and the Closing Date, the Company makes any capital expenditures with respect to one or more of the items set forth on the Capital Expenditure Plan with respect to such period, increased by the amount actually spent on such item(s) between November 1, 2009 and the Closing Date;

(vi) in the event the Company makes any capital expenditures (other than maintenance expenditures) on items not set forth on the Capital Expenditure Plan and such expenditures are specifically approved by Buyer pursuant to Section 7.2, increased by the approved amounts actually spent on such items between the date of this Agreement and the Closing Date;

(vii) increased by the amounts actually spent by the Company to purchase the Contactors; and

(viii) increased or decreased as otherwise mutually agreed upon by Sellers and Buyer.

EXECUTION COPY

(b) No later than ten Business Days prior to the Closing Date, Sellers will prepare and submit to Buyer a statement setting forth, in reasonable detail, Sellers’ good faith and reasonable computation of the estimated Working Capital of the Company (“Estimated Closing Working Capital”) and an estimated unaudited combined balance sheet of the Company as of immediately prior to the Effective Time (the “Estimated Closing Balance Sheet”) from which the Estimated Closing Working Capital is derived. The Estimated Closing Working Capital shall be in the form attached to this Agreement as Exhibit A. The Estimated Closing Balance Sheet and Estimated Closing Working Capital shall be prepared by Sellers using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation and accrual methodologies that were used in the preparation of the Company’s Financial Information (as defined in Section 4.9 below) as if such Estimated Closing Balance Sheet and Estimated Closing Working Capital were being prepared as of a fiscal year end. Sellers will furnish to Buyer, together with such computation, copies of back-up and other supporting information and such other documentation as Buyer may reasonably request that reasonably supports such computation. Buyer will have three Business Days after receipt of Sellers’ statement to review such statement. If Buyer fails to give notice of objection within the three Business Day period, then Sellers’ statement will be used for the purpose of determining the Adjusted Purchase Price to be paid on the Closing Date (the “Closing Date Adjusted Purchase Price”), which amount, for the avoidance of doubt, shall be subject to adjustment pursuant to Section 1.3(c). If Buyer, in good faith, objects to any portion of such statement, it will notify Seller in writing (setting forth, in reasonable detail, the reasons for such objections and, to the extent reasonably determinable by Buyer, Buyer’s computation of the adjustments to the Purchase Price) within three Business Days of receipt of Sellers’ statement and Buyer and Sellers will endeavor in good faith to resolve any disputed matters prior to Closing. If Buyer and Sellers resolve all disputed matters at least three Business Days prior to the Closing Date, the Closing Date Adjusted Purchase Price at Closing will be that mutually agreed amount. If Buyer and Sellers are unable to so resolve all disputed matters at least three Business Days prior to Closing, the Closing Date Adjusted Purchase Price will be based on Sellers’ statement (including any amount still being disputed by Buyer, but as adjusted to reflect all matters mutually agreed upon). At least one Business Day prior to the Closing Date, Sellers will notify Buyer in writing of the allocation of the Closing Date Adjusted Purchase Price between Sellers and wiring instructions for payment. The Closing Date Adjusted Purchase Price will be paid to Sellers at Closing in immediately available funds by confirmed wire transfer to a bank account or accounts designated by Sellers. For the avoidance of doubt, the Closing Date Adjusted Purchase Price shall be subject to adjustment pursuant to Section 1.3(c) regardless of the method by which the Closing Date Adjusted Purchase Price is determined.

EXECUTION COPY

(c) Within 90 days after the Closing Date, Buyer will cause to be prepared and delivered to Sellers a statement (the “Final Settlement Statement”) setting forth the amount of the final adjustments to the Purchase Price determined reasonably and in good faith in accordance with Section 1.3(a)) (including any adjustments to the Working Capital) (together with supporting documentation used by Buyer in calculating each such amount and otherwise in preparing the Final Settlement Statement and such other documentation as Sellers may reasonably request). The Final Settlement Statement shall be in the form attached to this Agreement as Exhibit A and shall be prepared by Buyer using the same accounting methods, practices, principles, policies and procedures, with consistent classifications, judgments and valuation and estimation and accrual methodologies that were used in the preparation of the Company’s Financial Information as if such Estimated Closing Balance Sheet and Estimated Closing Working Capital were being prepared as of a fiscal year end. Sellers will cooperate in good faith with Buyer in the preparation of the Final Settlement Statement, and will promptly, but in any event within 10 days after request, provide Buyer with, or access to, all documentation related to the Final Settlement Statement reasonably requested by Buyer. Within 30 days after the Final Settlement Statement is delivered to Seller, Seller will complete its examination thereof and may deliver to Buyer a written report setting forth in reasonable detail any objections or, to the extent reasonably determinable by Sellers, proposed adjustments to the Final Settlement Statement (the “Objection Notice”). Any objections or proposed adjustments that are not included in a proper Objection Notice delivered to Buyer within 30 days after Sellers’ receipt of the Final Settlement Statement are irrevocably waived and released by Sellers. Sellers and Buyer will each use Reasonable Efforts to resolve any objections to the Final Settlement Statement as described in the Objection Notice. If final resolution of such objections is not obtained within 30 days following the delivery of the Objection Notice, Sellers and Buyer will refer any unresolved objections to the Referral Firm for its resolution. The resolution by the Referral Firm will be binding on Sellers and Buyer, and will be final and non-appealable. In resolving any disputed item, the Referral Firm (i) shall be bound by the provisions of this Section 1.3 and (ii) may not assign a value to any item greater than the greatest value for such items claimed by either party or less than the smallest value for such items claimed by either party. Sellers will bear 50%, and Buyer will bear 50%, of the fees and expenses of the Referral Firm.

(d) Upon the resolution of the adjustments to the Purchase Price in accordance with Section 1.3(c) (whether by agreement of Sellers and Buyer (including Sellers’ failure to timely deliver an Objection Notice) or as determined by the Referral Firm), the amount of the Purchase Price as so adjusted will be the “Post-Closing Adjusted Purchase Price.” Within three Business Days after the determination of the Post-Closing Adjusted Purchase Price: (i) Buyer will tender to Sellers cash equal to the aggregate positive excess of the Post-Closing Adjusted Purchase Price over the Closing Date Adjusted Purchase Price or (ii) Sellers will, jointly and severally, tender to Buyer cash equal to the aggregate positive excess of the Closing Date Adjusted Purchase Price over the Post-Closing Adjusted Purchase Price, in each case, together with interest thereon from the Closing Date to the date of payment thereof (payable at the “prime” rate, as announced by The Wall Street Journal, from time to time to be in effect, calculated based on a 365 day year and the actual number of days elapsed). Upon the resolution of the adjustments to the Purchase Price in accordance with Section 1.3(c) (whether by agreement of Sellers and Buyer (including Seller’s failure to timely deliver the Objection Notice) or as determined by the Referral Firm), there will be no further adjustments to the Purchase Price (or Post-Closing Adjusted Purchase Price), except to the extent, and for the purposes, provided in Section 11.9 and with respect to Taxes as provided in Section 8.7.

Section 8.2 Confidentiality Agreement. The Confidentiality Agreement, except to the extent modified herein, will remain in full force and effect until Closing, at which time it will automatically terminate without further action by the parties to the Confidentiality Agreement.

Section 8.3 Reasonable Efforts. Each party to this Agreement agrees that it will not voluntarily undertake any course of action inconsistent with the provisions of this Agreement and will use its Reasonable Efforts to take, or cause to be taken, all action and to do, or cause to be done, all things reasonably necessary, proper, or advisable under Applicable Laws to consummate the transactions contemplated by this Agreement, including, without limitation, (i) cooperation in determining whether any consents, approvals, orders, authorizations, waivers, declarations, filings, Permit transfers or registrations of or with any Governmental Entity or third party are required in connection with the consummation of the transactions contemplated hereby; (ii) Reasonable Efforts to obtain any such consents, approvals, orders, authorizations, and waivers and to effect any such declarations, filings, Permit transfers, and registrations, including with respect to Sellers and the Company, obtaining any consent or releases required to satisfy the condition set forth in Section 9.1(h); (iii) Reasonable Efforts to cause to be lifted or rescinded any injunction or restraining order or other order adversely affecting the ability of the parties to consummate the transactions contemplated hereby; (iv) Reasonable Efforts to defend, and cooperation in defending, all lawsuits or other legal Proceedings challenging this Agreement or the consummation of the transactions contemplated hereby; and (v) the execution of any additional instruments necessary to consummate the transactions contemplated by this Agreement. If any required consent is not obtained at the time all other Closing conditions are satisfied (or waived by the party for whose benefit the condition exists), Buyer and Sellers or their Affiliate that is a party to the underlying agreement will enter into a “back-to-back” arrangement that provides Buyer substantially the same economic benefits and burdens as the underlying agreement. Notwithstanding anything to the contrary in this Agreement, neither Buyer nor any of its Affiliates (which for purposes of this sentence shall include the Company) shall be required, (i) to pay any fees or expenses on behalf of Sellers or the Company, (ii) to hold separate (including by trust or otherwise) or divest any of their respective businesses, product lines or assets, (iii) to agree to any limitation on the operation or conduct of their or the Company’s respective businesses or (iv) to waive any of the conditions set forth in Article IX of this Agreement.

Section 8.4 Notice of Litigation. Until the Closing, (i) Buyer, upon learning of the same, will promptly notify the Company and Sellers of any Proceeding which is commenced or threatened against Buyer and which affects this Agreement or the transactions contemplated hereby and (ii) each Seller and the Company, upon learning of the same, will promptly notify Buyer of any Proceeding which is commenced or threatened against that Seller or the Company and which affects this Agreement or the transactions contemplated hereby and any Proceeding which is commenced or threatened against the Company and which would have been listed on Section 4.10 of the Disclosure Schedule if such Proceeding had arisen prior to the date of this Agreement.

Section 8.5 Notification of Certain Matters.

(a) Each Seller will give prompt notice to Buyer of: (i) the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of which is reasonably expected to cause any representation or warranty made by such Seller in Article III to be untrue or inaccurate at or prior to the Closing and (ii) any failure of such Seller to comply with or satisfy any covenant, condition, or agreement to be complied with or satisfied by such Seller hereunder prior to Closing. The Company will give prompt notice to Buyer of: (i) the occurrence or nonoccurrence of any event, including any Post-Signing Event, the occurrence or nonoccurrence of which the Company has Knowledge and which is reasonably expected to cause any representation or warranty contained in Article IV to be untrue or inaccurate at or prior to the Closing, and (ii) any failure of the Company to comply with or satisfy any covenant, condition, or agreement to be complied with or satisfied by the Company hereunder prior to Closing of which the Company has Knowledge. Buyer will give prompt notice to the Company of: (i) the occurrence or nonoccurrence of any event the occurrence or nonoccurrence of which is reasonably expected to cause any representation or warranty contained in Article VI to be untrue or inaccurate at or prior to the Closing, and (ii) any failure of Buyer to comply with or satisfy any covenant, condition, or agreement to be complied with or satisfied by Buyer hereunder prior to Closing. If Buyer or any of its Affiliates obtains Knowledge of a breach by the Company or any Seller of a representation, warranty, covenant or agreement by the Company or any Seller contained in this Agreement, as promptly as practicable Buyer will notify the Company and Sellers of such breach; provided, however, that in no event shall the failure to provide such notice have any effect on the Parties’ respective obligations or rights to close or not close the transactions contemplated by this Agreement or the indemnification rights and obligations set forth in this Agreement. Prior to the Closing, the Company will use Reasonable Efforts to keep Buyer generally informed as to all material matters involving the current operations and business of the Company.

EXECUTION COPY

(b) Sellers will modify or supplement the Disclosure Schedule after the date of this Agreement and before Closing promptly upon becoming aware of any fact, change, condition, circumstance or event that has caused or is reasonably likely to cause any representation or warranty in Article III or IV to become untrue or inaccurate in any material respect. However, the delivery of any notice or of any supplements or amendments to the Disclosure Schedule will not be deemed to: (i) modify the representations or warranties hereunder of the party delivering such notice as of the date of this Agreement, (ii) modify the conditions set forth in Article IX or (iii) limit or otherwise affect the remedies (if any) available under this Agreement to the party receiving such notice; provided, however, that if the Closing occurs and the Disclosure Schedule has been supplemented or amended to reflect a Post-Signing Event which did not arise out of a breach of a representation, warranty or covenant of Sellers or the Company set forth in this Agreement as of the date of this Agreement, for the purposes of determining Sellers’ indemnification obligations pursuant to Article XI, the amendment or supplement of the Disclosure Schedule regarding such Post-Signing Event will be deemed to be included in the Disclosure Schedule for purposes of determining whether or not any breach of the representations and warranties of the Company has occurred.

Section 8.6 Employee Matters.

(a) Conditioned upon Closing, Buyer shall make offers of employment to commence immediately after the Closing to those Employees identified as “Offered Employees” in Section 8.6(a) of the Disclosure Schedule (the “Offered Employees”) as promptly as reasonably practicable and in any event within thirty (30) days after the date of this Agreement and Buyer may make offers of employment to commence immediately after the Closing to those Employees identified as “Additional Employees” in Section 8.6(a) of the Disclosure Schedule (the “Additional Employees”) as promptly as reasonably practicable and in any event no later than thirty (30) days after the date of this Agreement. Buyer must provide the Offered Employees and Additional Employees at least five (5) days to accept the offers. Buyer shall notify Sellers in writing of the names of those Employees who: (i) received offers of employment, (ii) accepted the offers and (iii) rejected or failed to accept the offers, in each case no later than five (5) days after the expiration of the five-day period allowed to accept the offers. Each such Offered Employees and Additional Employees who (i) accepts such offer on or before the Closing Date, (ii) passes a background check and a drug screen to be conducted by Buyer in its sole discretion prior to Closing, and (iii) reports to work on the Closing Date (or, if any Employee is on an approved absence (including vacation or illness), following the conclusion of the approved absence) is hereinafter referred to as a “Transferred Employee.” Section 8.6(a) of the Disclosure Schedule shall be updated as changes occur to the information contained in such list to reflect new hires, terminations or other personnel changes occurring between the date hereof and the Closing Date.

(b) Buyer shall offer each Offered Employee and each Additional Employee to whom Buyer makes an offer in accordance with Section 8.6(a) base salary or wages (excluding bonus and incentive compensation opportunities) at an annual rate equal to the annual rate currently in effect for that Employee as of the Closing Date. All Transferred Employees shall be eligible to participate in Buyer’s employee benefit plans for similarly situated employees immediately after the Closing Date. If Buyer’s 401(k) plan (or other defined contribution plan) permits rollover contributions and participant loans, that plan shall accept rollovers from the Transferred Employees’ accounts in the Seller’s 401(k) Plan, including outstanding participant loans that are not in default on the date of transfer. Nothing in this Section 8.6 shall obligate Buyer to maintain any particular employee benefit plans.

EXECUTION COPY

(c) Buyer shall recognize, and shall cause its employee benefit plans (having the same meaning as in Section 13.1 except that the plan is sponsored, maintained or contributed to by Buyer) to recognize, the service rendered by the Transferred Employees to Sellers, the Company and any of their Affiliates (and any of their predecessors) prior to the Closing Date for all purposes (except for benefit accruals under any benefit plan) under all compensation plans, programs, policies and arrangements (including severance plans) of Buyer from and after the Closing Date, to the same extent as such service was taken into account under the Seller’s corresponding plans covering the Employees for such purposes; provided, however, that nothing herein shall result in the duplication of any benefits; and provided, further, that with respect to accrual of vacation days, service shall be recognized to the extent permitted under Buyer’s existing vacation pay program or policy.

(d) Sellers and their Affiliates (other than the Company) shall retain (i) all liabilities, contingent or otherwise, with respect to the Employee Benefit Plans, (ii) all liabilities, contingent or otherwise, with respect to all employees and consultants of the Sellers or any of their Affiliates who are not Transferred Employees, and (iii) with respect to Transferred Employees, all liabilities, contingent or otherwise, attributable to the periods prior to the Closing.

(e) After the Closing the Transferred Employees shall be eligible to participate in Buyer’s severance plan in effect from time to time. If, within one year after the Closing Date, Buyer terminates any Transferred Employee under circumstances which would entitle such Transferred Employee to be paid under Buyer’s severance plan in effect as of the date of this Agreement, Buyer will pay to that Transferred Employee severance benefits in an amount calculated in accordance with Buyer’s severance plan in effect as of the date of this Agreement.

(f) If, within six (6) months after the Closing Date, Buyer hires as an employee any Offered Employee or Additional Employee who did not accept Buyer’s offer of employment pursuant to Section 8.6(a) (or, in the case of Additional Employees, who did not receive an offer of employment from Buyer), Buyer will pay to Sellers an amount equal to any severance benefits paid to such Employee by Sellers or their Affiliates.

(g) If any Offered Employee with an asterisk adjacent to his or her name in Section 8.6(a) of the Disclosure Schedule refuses Buyer’s offer of employment or does not accept his or her offer of employment prior to the Closing, Sellers shall terminate such Offered Employee as of the Closing Date, or, if such Offered Employee is providing transition service(s) pursuant to the Transition Services Agreement (and is not providing any other service(s) to Sellers or any of their Affiliates), as of the termination of such transition service(s), and shall not rehire or otherwise obtain the services of such Offered Employee for one year after the Closing Date.

EXECUTION COPY

(h) Except as expressly provided in this Section 8.6, for a period of one year following the Closing Date, Buyer and its Affiliates will not solicit, raid, encourage, entice or induce, directly or indirectly, any employee (or person who was an employee within the previous three months) of Sellers or their Affiliates or any other person who is under contract with or rendering services to Sellers or their Affiliates in an employee-like capacity in the day-to-day business operations of Sellers or their Affiliates, or who provides services to Sellers or their Affiliates on an exclusive or substantially full-time basis, during such one-year period, to (i) terminate his or her employment by, or contractual relationship with, Sellers or their Affiliates, (ii) refrain from extending or renewing the same (upon the same or new terms), (iii) refrain from rendering services to or for Sellers or their Affiliates, (iv) become employed by or to enter into contractual relations with any persons other than Sellers or their Affiliates, or (v) enter into an employment or contractual relationship with a competitor of Sellers or their Affiliates; provided that the foregoing shall not prohibit solicitations through advertisements and other customary employment marketing practices which are not targeted to any employees of Sellers or their Affiliates. For a period of one year following the Closing Date, none of Sellers, or any of their Affiliates shall solicit, raid, encourage, entice or induce, directly or indirectly, any Transferred Employee, to (i) terminate his or her employment with Buyer or any of its Affiliates, (ii) refrain from extending or renewing the same (upon the same or new terms), (iii) refrain from rendering services to or for Buyer or any of its Affiliates, (iv) become employed by or to enter into contractual relations with any persons other than Buyer or any of its Affiliates, or (v) enter into an employment or contractual relationship with a competitor of Buyer or any of its Affiliates; provided that the foregoing shall not prohibit solicitations through advertisements and other customary employment marketing practices which are not targeted to any Transferred Employees.

(i) For purposes of each Buyer’s employee benefit plan providing medical, dental, pharmaceutical and/or vision benefits to any Transferred Employee, Buyer shall cause all pre-existing condition exclusions and actively-at-work requirements of such plan to be waived for such Transferred Employee and his or her covered dependents. Buyer shall give effect, in determining any co-payments, coinsurance, deductible and maximum out-of-pocket limitations, to claims incurred and amounts paid by, amounts reimbursed to, and deductibles satisfied by the Transferred Employees for the calendar year in which the Closing Date occurs under any group health and welfare benefit plans maintained or contributed to by Sellers for their benefit immediately prior to the Closing Date.

(j) On or prior to the Closing Date, Sellers shall pay, to the extent and in a manner permitted under Section 409A of the Code, all accrued but unused vacation days and personal days of the Employees who are to become Transferred Employees as of the Closing Date, reduced by any obligation owed to Sellers by such Transferred Employee.

(k) Sellers shall be responsible for discharging all obligations under the Worker Adjustment and Retraining Notification Act (29 U.S.C. § 2101, et seq.) (“WARN Act”) and similar applicable local laws for the notification of Offered Employees and Additional Employees of any “employment loss” within the meaning of the WARN Act and similar applicable local law which occurs prior to the Closing Date. Buyer acknowledges that it has not informed Sellers of any planned or contemplated decisions or actions by Buyer that would require the service of notice under the WARN Act. Buyer agrees that it will not take, or omit to take, any action that causes the notice provisions of the WARN Act to be applicable to the transactions contemplated by this Agreement; provided that Sellers will provide Buyer at Closing with a list of employees assigned to the Treating Assets who have been terminated or notified of their termination during the ninety (90)-day period ending on the Closing Date.

EXECUTION COPY

(l) With respect to the Employees who become Transferred Employees (and their eligible dependents), (i) Sellers shall be responsible for satisfying obligations to provide COBRA continuation coverage with respect to any “qualifying event” occurring on or prior to the Closing Date and (ii) Buyer shall be responsible for satisfying obligations to provide COBRA continuation coverage with respect to any “qualifying event” which occurs after the Closing Date; provided that Sellers shall be responsible for satisfying the obligations to provide COBRA continuation coverage (at the Employee’s expense) to any Employees other than the Transferred Employees with respect to any “qualifying event” which occurs prior to, on or after the Closing Date. Buyer shall not, without Sellers’ written consent, pay or offer to pay any COBRA premium for any of the Transferred Employees (or other qualified beneficiaries whose coverage is based on a relationship to the Transferred Employee) who would be eligible for healthcare continuation under Sellers’ health benefit plan.

Section 8.7 Taxes.

(a) Sellers acknowledge that the Company is a disregarded entity for federal Tax purposes. Accordingly, Buyer and Sellers intend that the sale of the Interests will be treated for federal Tax purposes as a taxable sale of the Company’s assets (including the Assigned Assets) for the Adjusted Purchase Price and the assumption of liabilities of the Company. Sellers will be responsible, and agree to hold harmless and indemnify Buyer, for any and all sales, transfer, recordation or similar Taxes payable by virtue of the assignment of the Assigned Assets. Buyer will be responsible, and agrees to hold harmless and indemnify Sellers, for any and all Taxes of the Company (and those attributable to the Assigned Assets) for all Post-Closing Straddle Periods and for all tax periods beginning at or after the Effective Time. Each of Buyer, on the one hand, and Sellers, on the other hand, will be responsible, and agree to hold harmless and indemnify Buyer or Sellers, as applicable, for 50% of the sales, transfer, recordation or similar Taxes payable by virtue of this transaction. Buyer and Sellers agree not to take any position with respect to Taxes inconsistent with the intended tax treatment of this transaction and the provisions of this Section 8.7.

(b) Sellers will prepare and timely file, or cause to be prepared and timely filed, all Tax Returns of the Company that are required to be filed after the Effective Time with respect to any Pre-Closing Tax Period (the “Pre-Closing Returns”). Sellers will pay or cause to be paid all Taxes imposed on the Company shown as due and owing on such Pre-Closing Returns and any amendments to such Tax Returns, except to the extent any such Taxes are taken into account in determining the Adjusted Purchase Price pursuant to Section 1.3. Sellers will prepare or cause to be prepared the respective Pre-Closing Returns consistently with the most recent customs and practices of the Company, unless otherwise required by Applicable Law. The disclosures of matters on Section 4.12 of the Disclosure Schedule shall not have any effect on Sellers’ obligations pursuant to this Section 8.7.

EXECUTION COPY

(c) Buyer will prepare or cause to be prepared any Tax Return covering a Straddle Period that is required to be filed after the Effective Time with respect to the Company (the “Straddle Period Returns”) consistent with the most recent customs and practices of the Company (or its Affiliate, as applicable), unless otherwise required by Applicable Law. Within a reasonable period of time prior to the due date (including extensions) of any Straddle Period Return, Buyer will furnish a copy of such Straddle Period Return to Sellers, together with a request for Sellers’ payment to Buyer of the amount of Taxes attributable to the Pre-Closing Straddle Period and reasonable supporting documentation. If Sellers have no objections to the content of the Straddle Period Return, Sellers will pay Buyer the amount requested. Buyer will thereafter pay such amount to the Governmental Entity to which the Taxes are owed and provide reasonable documentation to Sellers confirming such payments within ten days of the dates of such payments. Sellers will notify Buyer in writing of the existence of any comments or objections (specifying in reasonable detail the nature and basis of such comments or objections) of Sellers to any items set forth on the draft Straddle Period Return for the Company (a “Tax Dispute Notice”). Buyer and Sellers will consult and resolve in good faith any such objection. If Buyer and Sellers, notwithstanding such good faith effort, fail to resolve the dispute within 30 days after the Tax Dispute Notice was delivered to Buyer, then Sellers and Buyer will submit such dispute to the Referral Firm. The resolution of the Referral Firm will be binding on Sellers and Buyer, and will be final and non-appealable. Sellers will bear 50%, and Buyer will bear 50%, of the fees and expenses of the Referral Firm. Notwithstanding the foregoing, the terms and provisions of this Section 8.7(c) will not prohibit Buyer from timely filing the Straddle Period Returns, but Buyer will file, or cause to be filed, an amended Straddle Period Return to the extent necessary to reflect the applicable parties’ agreed resolution of the objections contained in the Tax Dispute Notice or the determination of the Referral Firm after the original filing due date.

(d) For purposes of allocating Taxes of the Company between that portion of the Straddle Period ending prior to the Effective Time (the “Pre-Closing Straddle Period”) and that portion of the Straddle Period beginning at the Effective Time (the “Post-Closing Straddle Period”), the portion of such Taxes related to the Pre-Closing Straddle Period will be deemed to be: (i) in the case of Taxes (other than income Taxes, franchise and margin Taxes, Taxes measured in whole or in part by reference to gross revenues or receipts, income, excise, employment, withholding, gross receipts and other similar Taxes and sales and use Taxes), equal to the amount of such Taxes for the entire Straddle Period multiplied by a fraction the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Straddle Period and the denominator of which is the number of days in the Straddle Period, provided that Sellers will not be required to pay any Taxes to the extent such Taxes were taken into account in determining the Adjusted Purchase Price pursuant to Section 1.3; and (ii) in the case of income Taxes, franchise and margin Taxes, Taxes measured in whole or in part by reference to gross revenues or receipts, income, excise, employment, gross receipts and other similar Taxes and sales and use Taxes will be allocated between the Pre-Closing Straddle Period and the Post-Closing Straddle Period as though the taxable year of the Company terminated based on interim closing of the books as of the Effective Time, and based on accounting methods, elections and conventions that do not have the effect of distorting income and expenses. All determinations necessary to give effect to the foregoing allocations will be made in a manner consistent with the past practice of the Company with respect to such items, unless otherwise required by Applicable Law.

EXECUTION COPY

(e) Buyer will notify each Seller promptly after receipt by Buyer or any Affiliate of Buyer of written notice of any inquiries, claims, assessments, audits or similar events with respect to Taxes relating to a Pre-Closing Tax Period or Straddle Period for which a Seller may be liable under this Agreement (any such inquiry, claim, assessment, audit or similar event, a “Tax Matter”). Sellers, at their own expense, will have the exclusive authority to represent the interests of the Company for any Pre-Closing Tax Period with respect to any Tax Matter before the IRS or any other Governmental Entity involving the Company and will have the sole right to control the defense, compromise or other resolution of such Tax Matters, including responding to inquiries, filing Tax Returns and settling audits. Buyer will execute or cause to be executed powers of attorney or other documents necessary to enable Sellers to take all actions desired by Sellers with respect to such Tax Matter. Sellers may in their sole discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any Governmental Entity with respect to such Tax Matter, and may initiate any claim for refund, file any amended return, or take any other action which is deemed appropriate by Sellers with respect to such Tax Matter. Notwithstanding the foregoing, Sellers and Buyer will jointly control all proceedings in connection with any Tax Claim relating solely to Taxes for a Straddle Period, and will equally bear and pay costs and expenses related to such proceedings. No party will settle a Tax Matter relating solely to Taxes of the Company for a Straddle Period without the other party’s prior written consent (which consent may not be unreasonably withheld, conditioned or delayed; and which consent will be considered to be unreasonably withheld if such settlement has no adverse effect on the other party).

(f) Buyer and its Affiliates (including after the Closing, the Company), on the one hand, and Sellers, on the other hand, will cooperate with each other in contesting any Tax Matter, which cooperation will include, without limitation, the retention and, at the contesting party’s request and expense, the provision of records and information which are reasonably relevant to such Tax Matter, and making employees available on a mutually convenient basis to provide additional information or explanation of any material provided hereunder or to testify at proceedings relating to such Tax Matter.

(g) Buyer will not file or cause to be filed any amended Tax Returns covering any period or adjusting any Taxes for a period which includes any Pre-Closing Tax Period or a Straddle Period without the prior written consent of Sellers, which may be withheld in Sellers’ sole discretion.

(h) Any refund or credits of Taxes paid or payable that are attributable to the Company for any Pre-Closing Tax Period or any Pre-Closing Straddle Period will be for the account of Sellers, except that any refund or credit to the extent taken into account in determining the Adjusted Purchase Price pursuant to the Final Settlement Statement shall be retained by Buyer. Any refunds or credits of Taxes paid or payable that are attributable to the Company for any other taxable period will be for the account of Buyer. Buyer, if Sellers so reasonably request and at Sellers’ expense, will cause the Company to file for and obtain any refunds or credits to which Sellers are entitled. Buyer will cause the Company to forward to Sellers any such refund within ten (10) days after the refund is received (or reimburse Sellers for any such credit within (10) days after the credit is applied against another Tax liability); provided, however, that Sellers will indemnify Buyer for any amount paid pursuant to this Section 8.7(h) if any such refund or credit is subsequently disallowed.

EXECUTION COPY

(i) The Adjusted Purchase Price (together with the liabilities of the Company assumed by Buyer) will be allocated among the Company’s assets (including the Assigned Assets) in accordance with Section 1060 of the Code and the Treasury regulations thereunder (and any similar provision of state or local law, as appropriate) (the “Allocation”). Buyer will provide a proposed Allocation to Sellers in writing at least 15 days prior to Closing, and thereafter Buyer and Sellers will act in good faith and reasonably cooperate with each other for not less than 45 days after the Closing to agree on the final Allocation. If the parties are unable to agree upon the final Allocation prior to the date 45 days after Closing, Sellers and Buyer shall submitted any disputed items to the Referral Firm for resolution, and the determination of such disputed items by the Referral Firm shall be final and binding upon both parties.

(l) To the extent the ad valorem, property or similar Taxes taken into account in determining the Post-Closing Adjusted Purchase Price exceed the actual amount of said Taxes payable for the Pre-Closing Straddle Period, Buyer will cause the Company to pay said excess amount to Sellers within ten (10) days after the actual amount of said Taxes allocable to the Pre-Closing Straddle Period is determined.

Subject to the terms and conditions of this Article XI, from and after Closing, Buyer and the Company will jointly and severally indemnify, defend and hold harmless Sellers, their Affiliates, and their respective directors, managers, partners, officers, agents, employees, successors and assigns (“Seller Indemnitees”) from and against any and all Damages asserted against, resulting to, imposed upon, or incurred by any of them, directly or indirectly, by reason of, attributable to or resulting from (i) any breach by Buyer of its representations, warranties, covenants and agreements contained in this Agreement or the certificate delivered by Buyer pursuant to Section 9.1(c) and (ii) except to the extent Sellers are required to indemnify or otherwise pay or hold harmless Buyer Indemnitees in accordance with Sections 11.2, 8.6 or 8.7, matters to the extent attributable to the ownership and the operations of the Company and its properties and other assets, including the Assigned Assets, in each case, from and after the Effective Time.

Section 11.4 Indemnification Proceedings. If any claim or demand for which a party (an “Indemnifying Party”), would be liable to another party to this Agreement under Section 11.2 or Section 11.3 (“Indemnified Party”) is asserted against or sought to be collected from an Indemnified Party by a third party, the Indemnified Party will with reasonable promptness notify the Indemnifying Party of such claim or demand, but the failure so to notify the Indemnifying Party will not relieve the Indemnifying Party of its obligations under this Article XI, except to the extent the Indemnifying Party demonstrates that the defense of such claim or demand is materially prejudiced thereby. The Indemnifying Party will have 30 days from receipt of the above notice from the Indemnified Party (in this Section 11.4, the “Notice Period”) to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party’s sole cost and expense, to defend the Indemnified Party against such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it deems necessary or appropriate to protect its interests or those of the Indemnifying Party and not prejudicial to the Indemnifying Party. If the Indemnifying Party elects to assume the defense of any such claim or demand, the Indemnified Party will have the right to employ separate counsel at its own expense and to participate in the defense thereof. If the Indemnifying Party elects not to assume the defense of such claim or demand (or fails to give notice to the Indemnified Party during the Notice Period), the Indemnified Party will be entitled to assume the defense of such claim or demand with counsel of its own choice, at the expense of the Indemnifying Party. If the claim or demand is asserted against both the Indemnifying Party and the Indemnified Party and based on the advice of counsel reasonably satisfactory to the Indemnifying Party it is determined that there is a conflict of interest which renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party will be responsible for paying separate counsel for the Indemnified Party; provided, however, that the Indemnifying Party will not be responsible for paying for more than one separate firm of attorneys to represent all of the Indemnified Parties, regardless of the number of Indemnified Parties. If the Indemnifying Party elects to assume the defense of such claim or demand, (i) no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnified Party’s written consent (which will not be unreasonably withheld) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and (ii) the Indemnified Party will have no liability with respect to any compromise or settlement thereof effected without its written consent (which will not be unreasonably withheld).

Section 11.5 Exclusivity. Except as otherwise provided in Section 8.1(b), Section 8.6, Section 8.7, the proviso in the first sentence of Section 8.19, the proviso in the first sentence of Section 8.20, Section 8.21 and the second sentence of Section 12.7, each Seller, the Company and Buyer agree that after Closing, the sole and exclusive relief and remedy available to any party to this Agreement in relation to any breach, default, or nonperformance of any representation, warranty, covenant, or agreement made or entered into by a party to this Agreement or under any certificate, instrument, or document delivered pursuant to this Agreement: (a) will be Damages, and (b) any claim for those Damages can only be brought under, and in accordance with, the terms and provisions of this Article XI.

No statement in this Agreement specifying that any particular lost profit shall constitute actual Damages shall be deemed to imply that any other lost profit does not constitute actual Damages; any determination with respect to whether any other lost profit is an actual Damage shall be determined in accordance with Applicable Law as if this Agreement contained no statement with respect to lost profits.

Section 11.7 Limitation of Liability.

(a) Except for Damages arising from a breach of Section 3.1 (Title to Interests), Section 3.3 (Authority), the first sentence of Section 4.1 (Organization), Section 4.3 (Capital Structure), the first and last sentences of Section 4.4 (Power and Authority), Section 4.8 (Subsidiaries), the first sentence of Section 4.9 (Indebtedness), Section 4.12 (Taxes), Section 4.16 (Employee Related Matters) or Section 4.21 (Brokers) (the “Sellers Fundamental Representations”) or covenants or agreements in this Agreement, Sellers will not be required to indemnify or hold harmless the Buyer Indemnitees on account of Damages arising from any specific breach or claim (with related or similar matters arising out of the same facts and circumstances being grouped together in a single breach or claim) unless the liability in respect of those Damages exceeds $75,000 (or with respect to, and only with respect to, a breach of the representation set forth in the last sentence of Section 4.9, $500,000) (each a “Recoverable Claim”) and until the liability of Sellers in respect of aggregated Recoverable Claims exceeds the amount that is equal to $4,000,000, and then only for Recoverable Claims in excess of $4,000,000.

(b) Subject to all of the terms and conditions of this Article XI, Sellers’ indemnity obligations will not exceed: (a) for all indemnifiable Damages (except for Damages arising from a breach of the Sellers Fundamental Representations or covenants or agreements in this Agreement), Sellers will never be liable for more than twenty percent of the total Post-Closing Adjusted Purchase Price, and (b) for Damages arising from a breach of the Sellers Fundamental Representations or covenants or agreements in this Agreement, Sellers will never be liable for more than the total Post-Closing Adjusted Purchase Price (the maximum limit in (a) or (b) as applicable being the “Crosstex Cap Limitation”). Buyer hereby waives and releases Sellers from any Damages in excess of the Crosstex Cap Limitation.

(c) Subject to all of the terms and conditions of this Article XI, the Company’s indemnity obligations pursuant to the last sentence of Section 11.3 shall not exceed $10,000,000.

EXECUTION COPY

(d) For purposes of determining the failure of any representations or warranties to be true and correct, and calculating Damages for any such failure, any materiality or Material Adverse Effect qualifications in the representations and warranties shall be disregarded; provided, however, that materiality qualifications shall not be read out for the purposes of determining the failure of the representations and warranties set forth in the last sentence of Section 4.9.

(e) Sellers shall have no right of contribution or other recourse against the Company or its post-Closing Affiliates or their respective directors, officers, employees, Affiliates, agents, attorneys, representatives, assigns or successors for any Damages asserted by Buyer Indemnitees pursuant to this Agreement, it being acknowledged and agreed that the covenants and agreements of the Company are solely for the benefit of the Buyer Indemnitees.

Section 11.8 Indemnification Despite Negligence. It is the express intention of Sellers, the Company and Buyer that each party to be indemnified pursuant to this Article XI will be indemnified and held harmless as provided for under this Article XI, notwithstanding that any Damages that are otherwise subject to the indemnity arise out of or result from the ordinary, strict, sole, or contributory negligence of such party and regardless of whether any other party (including the other parties to this Agreement) is or is not also negligent. Except as specifically provided in this Agreement, the right to indemnification or any other remedy based on representations, warranties, covenants and agreements in this Agreement or any other agreement delivered pursuant to this Agreement shall not be affected by any investigation conducted at any time, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of, or compliance with, any such representation, warranty, covenant or agreement. Expect as otherwise specifically set forth in the proviso in clause (iii) of Section 8.5(b), the waiver of any condition based on the accuracy of any such representation or warranty, or on the performance of or compliance with any such covenant or agreements, will not affect the right to indemnification or any other remedy based on such representations, warranties, covenants and agreements. Sellers, the Company and Buyer acknowledge that the foregoing complies with the express negligence rule and is conspicuous.

Section 11.9 Tax Treatment of Indemnity Payments. All indemnity payments made under this Agreement, including any payment made under Section 8.7, will be treated as Purchase Price adjustments for Tax purposes.
