THIS EQUITY INTEREST PURCHASE AGREEMENT (this “Agreement”) is made effective the 21st day of February, 2007, between WCA of Oklahoma, LLC, a Delaware limited liability company (“Buyer”), as buyer, Xxx Xxxxxx Xxxxxx, an individual (“Xxx”), and Xxxx Xxxxxxx Xxxxxx, an individual (“Xxxx”, and collectively with Xxx, the “Sellers”), as sellers, and American Waste, Inc., an Oklahoma corporation (“AW”), N.E. Land Fill, Inc., an Oklahoma corporation (“NE”), Pauls Valley Landfill, Inc., an Oklahoma corporation (“PV”), and Sooner Waste, L.L.C., an Oklahoma limited liability company (“SW”) (each of AW, NE, PV and SW are hereinafter referred to individually as a “Company” and collectively as the “Companies”). Buyer, Sellers and the Companies are sometimes hereinafter referred to individually as a “Party” and collectively as the “Parties.”

WHEREAS, Sellers are the sole record and beneficial owners of all of the issued and outstanding capital stock of each of AW, NE, and PV (all such capital stock collectively referred to hereinafter as the “Shares”), and are the record and beneficial owner of all of the issued and outstanding membership interests of SW (the “Membership Interests”, and collectively with the Stock, the “Equity Interests”); and

WHEREAS, AW is in the waste collection and hauling business in and around Oklahoma City, Oklahoma; and

WHEREAS, NE, PV and SW are in the waste disposal business in and around Oklahoma City, Oklahoma (collectively, the businesses of AW, SW, NE and PV are hereinafter referred to as the “Business”); and

WHEREAS, Sellers wish to sell and Buyer wishes to purchase all of the issued and outstanding Equity Interests of the Companies.

NOW, THEREFORE, in consideration of the premises and of the mutual agreements set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto do hereby agree as follows:

1. PURCHASE OF EQUITY INTERESTS

Subject to the terms and conditions of this Agreement, Buyer will purchase from Sellers, and Sellers will sell, deliver and assign to Buyer, all of the Equity Interests for the consideration specified below.

2. CONSIDERATION

2.1 Purchase Price. Subject to the terms and conditions set forth in this Agreement, the aggregate purchase price to be paid for the Equity Interests shall be the sum of (i) THIRTY-NINE MILLION AND NO/100 DOLLARS ($39,000,000.00) (the “Fixed Purchase Price”), and (ii) the Variable Purchase Price, as set forth in Section 2.2 hereinbelow, (collectively the “Purchase Price”), as adjusted by: (a) a reduction equal to the amount required to fully pay off,

release and satisfy all debt (or similar payment obligations) underlying any and all of the assets of the Companies, including, without limitation, all unpaid purchase price financing and/or equipment lease obligations relating to any assets of any of the Companies, together with any early payoff penalties and other associated charges, provided, however, that the Purchase Price shall not be reduced by the outstanding indebtedness of the Companies to the Sellers which amount shall be deemed fully paid and satisfied in connection with the Closing, (b) the Working Capital Adjustment set forth in Section 2.3 herein; and (c) the Fixed Capital Adjustment set forth in Section 2.4 (as so adjusted, the “Adjusted Cash Purchase Price”). The Fixed Purchase Price shall be allocated between the purchase of the Equity Interests of the Companies as set forth on Exhibit 2.1 attached hereto and made a part hereof.

2.2 Variable Purchase Price. As a part of the consideration set forth in Section 2.1, Buyer, its successors and assigns, will pay to Sellers, their heirs, successors and assigns, the aggregate sum of $1.00 per ton of waste delivered to and disposed at the landfills currently owned by NE, SW and PV, and pursuant to each of the Oklahoma Department of Environmental Quality (“ODEQ”) permits and any renewals, amendments, and expansions (whether vertical or horizontal) adjacent or contiguous to the footprint of such landfill existing as of Closing (the “Variable Purchase Price”). The Variable Purchase Price will be paid quarterly, on an installment basis, based upon the waste delivered in the immediately preceding calendar quarter (or partial quarter in the case of the first calendar quarter of 2007). Payments will be made to Sellers or their heirs, successors and assigns, within thirty (30) days of the close of each calendar quarter and shall not be subject to any set off for claims which Buyer may have against Sellers except as set forth in Section 7.6 hereinbelow. Buyer and Sellers agree that a memorandum of agreement (the “Memorandum of Agreement”) in substantially the same form as Exhibit 2.2 attached hereto will be filed of record in each county or counties where such landfills are located. The Memorandum of Agreement provides notice of the binding agreement between Sellers, Buyer, Companies, their successors and assigns. Sellers, their heirs, successors and assigns shall have the right to audit the Variable Purchase Price to be paid on each separate landfill by giving written notice to the Buyer and Companies. Buyer and Companies, their successors and assigns shall reasonably cooperate to provide documentation to show that the installment payment of the Variable Purchase Price has been properly calculated and paid as set forth herein.

2.3 Working Capital Adjustment. If the Companies’ ratio of Current Assets to Current Liabilities (each as defined in Article 11) is not 1.0 to 1.0 as of the Closing Date, then the Purchase Price will be adjusted as follows:

(a) the Sellers shall estimate the Current Assets and Current Liabilities of the Companies as of the Closing Date. In connection therewith, Sellers shall develop a worksheet and the basis for making the computations of Current Assets and Current Liabilities (the “Worksheet”) that will also be used to determine the Actual Working Capital Adjustment pursuant to Section 2.3(b). If the estimated Current Liabilities exceed the estimated Current Assets, the amount of such excess shall be deducted on a dollar-for-dollar basis from the Purchase Price. If the estimated Current Assets exceed the estimated Current Liabilities, the amount of such excess shall be added on a dollar-for-dollar basis to the Purchase Price. Any such adjustment is referred to as the “Working Capital Adjustment.”

(b) Within ninety (90) days of Closing, the Buyer may, but shall not be required to, deliver to the Sellers a statement (the “Closing Statement”) setting forth what Buyer believes are the actual Current Assets and Current Liabilities as of the Closing Date, together with (a) any adjustment Buyer determines is required to be made to those receivables for which Sellers were paid on a dollar-for-dollar basis, and (b) the amount of the proposed Actual Working Capital Adjustment. In the event that the Buyer fails to deliver the Closing Statement within ninety (90) days of Closing, no adjustment to the Purchase Price will be made pursuant to this Subsection 2.2(b) or otherwise. In the event the Buyer shall prepare a Closing Statement, the Buyer will prepare the Closing Statement using the worksheet in the form of Exhibit 2.2 and it will be prepared in accordance with the provisions of this Agreement. The Closing Statement shall contain a supporting schedule detailing the proposed Actual Working Capital Adjustment, and be accompanied with copies of the work papers and back up materials used by Buyer in preparing the Closing Statement. Buyer will then present the Closing Statement to the Sellers. Sellers shall have the opportunity to review and object to any entry on the Closing Statement for a reasonable period of time not to exceed ten (10) days (“Seller Review Period”). Following the Seller Review Period the Parties agree to meet within ten (10) business days thereafter for the purpose of resolving in good faith any dispute regarding any proposed Actual Working Capital Adjustment contained on the Closing Statement. If the proposed Actual Working Capital Adjustment is a positive amount, the Buyer shall pay to the Sellers, an amount equal to such positive amount within fifteen (15) days from the date of the Parties meeting to resolve any good faith dispute regarding the proposed Actual Working Capital Adjustment. If the Actual Working Capital Adjustment is a negative amount, Sellers shall pay to the Buyer an amount equal to such negative amount within fifteen (15) days from the date of the Parties meeting to resolve any good faith dispute regarding the proposed Actual Working Capital Adjustment. Seller and Buyer agree that any Actual Working Capital Adjustment will be an addition to or reduction of the Adjusted Cash Purchase Price set forth in Section 2.1 hereinabove.

2.4 Fixed Capital Adjustment. Seller has agreed to make capital expenditures in the amount of $2,000,000 for a variety of capital items, including expenditures for the purpose of completing the Phase 2 new cell at the Pauls Valley landfill (collectively “Fixed Capital Expenditures”). On or before Closing, Seller shall deliver to Buyer Schedule 2.4 which contains a detail of the all Fixed Capital Expenditures made by Companies (by date, type and amount) between September 1, 2006 and the Closing Date. The Fixed Capital Adjustment will be equal to the difference between (a) $2,000,000, and (b) the Fixed Capital Expenditures. The Purchase Price shall be decreased by an amount equal to the Fixed Capital Adjustment.

With respect to the real property owned by any of the Companies (the “Owned Real Property”), Sellers shall, within ten (10) days after the date of this Agreement, deliver or cause to be delivered to Buyer (i) a commitment for title insurance (a “Title Commitment”), from a title company of Buyer’s choice (the “Title Company”), setting forth the status of the title of the Owned Real Property and showing all title encumbrances and other matters of record (“Real Property Encumbrances”) and all improvements thereon; and (ii) a true, complete and legible copy of all documents referred to in such Title Commitment. One-half of the costs for the Title Commitment will be paid by Buyer, and one-half of the costs for the Title Commitment will be paid by Sellers.

(b) Survey. Within ten (10) days after the date of this Agreement, Seller shall obtain a survey for the Owned Real Property (the “Survey”) consisting of a plat and field notes. The Survey shall be prepared pursuant to a current on-the-ground staked survey performed by a registered public surveyor or engineer satisfactory to Buyer and the Title Company. The Survey shall conform to the standards of the Oklahoma Society of Professional Surveyors, and (i) reflect the location and actual dimensions of and the total number of square feet of land and improvements comprising the Owned Real Property, (ii) identify any rights-of-way, improvements, easements, or any Real Property Encumbrances by applicable recording reference, (iii) identify any protrusions, encroachments, fences, building lines, public utilities not of record, and flood plain status, and (iv) include the Surveyor’s registered number and seal, the date of each Survey and a narrative certificate acceptable to Buyer and the Title Company. One-half of the costs for the Survey will be paid by Buyer, and one-half of the costs for the Survey will be paid by Sellers.

(c) Title and Survey Objections. If the Title Commitment or Survey fail to show good and indefeasible fee simple title to the Owned Real Property to be in one or more of the Companies, free and clear of all Real Property Encumbrances, then Buyer shall give Sellers written notice thereof within ten (10) days after Buyer’s receipt of the last of the Title Commitment, Survey, and all documents referred to therein, specifying Buyer’s objections (“Objections”), if any. At Closing, Sellers will provide releases for any deed of trust liens, judgment liens, mechanics liens, delinquent taxes, or any other monetary liens, if any, encumbering the Owned Real Property. If Buyer gives such notice to Sellers, then Sellers, at Sellers’ option, may cure the Objections during the Cure Period (as defined below).

(d) Cure Period. If Buyer gives such notice of Objections and Sellers do not cure or elect not to cure the Objections and, if applicable, cause the Title Commitment and Survey to be amended to give effect to matters that are cured and give Buyer written notice thereof within ten (10) days following receipt of the written notice of Objections from Buyer (“Cure Period”), Buyer may either (i) terminate this Agreement by giving written notice (the “Buyer Termination Notice”) thereof to Sellers and the Title Company at any time prior to Closing, and neither party hereto shall have any further rights or obligations hereunder, except those rights and obligations specifically surviving the termination of this Agreement; or (ii) waive the Objections and close the purchase of the Company subject to the Objections which shall be deemed to be “Permitted Title Encumbrances.” Notwithstanding the foregoing sentence, if Sellers have commenced curing the Objections during the Cure Period and is diligently prosecuting the cure, then Buyer in Buyer’s sole discretion may extend the Closing for an amount of time Buyer deems necessary for Sellers to cure the Objections.

(e) Review of Documents. Within ten (10) days after the date of this Agreement, Sellers shall deliver to Buyer for Buyer’s review (i) copies of the tax statements covering the Owned Real Property for the year prior to the current year and, if available, for the current year, (ii) copies of any leases affecting the Owned Real Property, if any, (iii) copies of all reports, surveys, and studies, including, without limitation, any environmental studies, prepared by or on behalf of Sellers with respect to the Owned Real Property, and (iv) copies of any documents, notices, or information in Sellers’ or any Company’s possession relating to any easements or claims of easement, rights, rights-of-way, licenses or other unrecorded interests of third parties (other than pursuant to the leases) in and to the Owned Real Property, the condition of the Owned Real Property, including any environmental condition or condition constituting a violation of any ordinance, regulation, law, or statute of any governmental agency, including, without limitation, any Environmental Law or zoning ordinance; and any threatened or pending administrative or condemnation proceedings or litigation with respect to the Owned Real Property.

(f) Inspections and Tests. At any time prior to Closing, Buyer and its agents, contractors, or representatives, at Buyer’s sole cost, may go on to the Real Property to make inspections, surveys, test borings, environmental inspections, and other tests and surveys; provided, however, that upon completion of such tests Buyer will restore the Real Property to substantially the condition as existed prior to such tests.

5.16. Audit. Upon the execution of this Agreement, Sellers will engage external auditors to audit the Companies’ financial records (including up to three years of historical data). Sellers, to the extent reasonable and appropriate and otherwise consistent with the terms of this Agreement, shall cooperate with such audit and will assist in the completion of such audit, including by providing such documents that are necessary to complete the audit and by making representations regarding the Companies’ businesses and the Companies’ financial records relating to any period preceding the Closing, but only to the extent that such actions are requested in writing by, or at the direction of, WCA’s external auditors (including having the Companies’ financial records converted, for Buyer’s use only, to accrual based accounting financials in accordance with GAAP). Buyer will reimburse Sellers for their out-of pocket costs and expenses

related to this audit. The results of such audit shall not be a basis for Buyer to reduce the Purchase Price.

5.17 [INTENTIONALLY OMITTED]

5.18 Supplementation of Schedules. The Companies and Sellers shall update, supplement and/or modify any schedule attached hereto as necessary such that each is accurate and complete as of the Closing.

5.19 Allocation of Purchase Price. The Purchase Price and other relevant items shall be allocated among the assets of the Companies in accordance with their fair market value, as reasonably determined by the Buyer and the Sellers in accordance with Sections 338, 754, 755 and 1060 of the Code and the regulations thereunder. The parties shall report for federal tax purposes in a manner consistent with such allocation on IRS Form 8883, and such other forms as may be required, and in accordance with, the relevant provisions of the Code. At the Buyer’s direction, the Companies and each of the Sellers will join with Buyer, if applicable, in making an election under sections 338(h)(10) and 754 of the Code (and any corresponding election under state, local, and foreign tax law) with respect to the purchase and sale of the stock of Companies hereunder (the “Election”). Sellers will include any income, gain, loss, deduction, or other tax item resulting from the Election on their Tax Returns to the extent required by applicable law. At closing, the Buyer and Sellers shall execute all necessary forms to effectuate the Elections, and said executed forms shall be delivered to Buyer at Closing.

5.20 Substitution of Financial Assurance. At Closing Buyer agrees to deliver to Sellers evidence that Buyer, on behalf of the Companies, has obtained financial assurance which will be delivered to the Oklahoma Department of Environmental Quality (“ODEQ”) in the normal course of Buyer’s business. Such financial assurance will be in an amount sufficient to permit the ODEQ to replace all financial assurance mechanisms currently on deposit for the benefit of the ODEQ for the closure and post-closure obligations of the Companies (all of which are described on Schedule 5.20 and referred to herein as the “Existing Financial Assurance”). Buyer will cooperate with the Sellers to obtain the release of any Existing Financial Assurance and any collateral backing such Existing Financial Assurance. Immediately upon the release of the Existing Financial Assurance or such collateral by the ODEQ, Buyer will deliver to Sellers all sums not delivered to the Sellers directly by the ODEQ. IT IS EXPRESSLY UNDERSTOOD AND AGREED BY BOTH PARTIES THAT SELLERS WILL NOT BE RESPONSIBLE IN WHOLE OR IN PART FOR PAYMENT OF ANY CLOSURE OR POST-CLOSURE REQUIREMENTS OR PAYMENT TO ODEQ RELATED THERETO.

5.21 Transition Operations. For a period of 120 days following the date of Closing, without additional consideration, Sellers agree to assist Buyer with the orderly transition of the operations of the Business from Sellers to Buyer. Such assistance shall include, without limitation, assisting Buyer in obtaining contracts with current customers, routing transition activities and developing sufficient information to allow Buyer to compile accurate customer xxxxxxxx. The foregoing is not intended to require Sellers to maintain regular office hours or work on anything other than a part-time basis. Any and all costs or expenses incurred by Sellers, including travel expenses in connection with the foregoing, shall be paid by Buyer.

6. NONCOMPETITION

6.1 Prohibited Activities:

(a) Except as set forth in the following paragraph, neither Sellers nor either Seller’s spouse (collectively, the “Restricted Parties”), shall for any reason whatsoever, directly or indirectly, for himself or itself or on behalf of or in conjunction with any other person, company, partnership, corporation or business of whatever kind or nature, engage, as an officer, director, shareholder, owner, member, partner, joint venturer, lender or in any other capacity, whether as an employee, independent contractor, consultant, advisor, or otherwise, or as a sales representative, of any business in direct or indirect competition with any Company or Buyer or an Affiliate of Buyer located or operating within *** (as exist at the time of Closing) (the “Non-Compete Area”, which is attached as Exhibit 6.1(a)) .

Notwithstanding the foregoing provisions of this paragraph (a) each Restricted Party may (i) be a passive investor owning no more than five percent (5%) of the outstanding equity securities of any corporation or other entity the equity securities of which are listed on a national securities exchange or traded on the NASDAQ National Market System and with which such persons have no other connection whatsoever and/or (ii) invest in or act as an employee of, consultant for, or hold another position with, Buyer or an Affiliate of Buyer;

(b) The Restricted Parties shall not, and each of them shall cause each of his Affiliates not to, offer to employ any person who is, at that time, or who has been within two (2) years prior to that time, an employee of any Company or Buyer;

(c) With respect to operations or transactions in the Non-Compete Area, the Restricted Parties shall not, and each of them shall cause his Affiliates to not, engage or participate in any effort or act to solicit or induce any customer, supplier, associate, employee, sales or other agent, independent contractor, or other person in a business relationship with Buyer or any Company, or which has been a customer, supplier, associate, employee, sales or other agent, independent contractor, or other person in a business relationship with Buyer or any Company within three (3) years prior to that time, to discontinue such relationship with Buyer or such Company, or to take any action which is calculated to harm Buyer or such Company;

(d) With respect to operations or transactions in the Non-Compete Area, none of the Restricted Parties shall, for any reason whatsoever, directly or indirectly for himself or on behalf of or in conjunction with any other person, company, partnership, corporation or business of whatever kind or nature, call upon any prospective acquisition candidate of such persons, on such persons’ behalf or on behalf of any competitor.

(e) The time period for the restrictions set forth in this Article 6 shall be *** after the Closing Date.

6.2 Damages. The Restricted Parties each acknowledge that the damages that would be suffered by Buyer as a result of any breach of the provisions of this Article 6 may not be calculable and that an award of a monetary judgment for such a breach would be an inadequate

remedy. Consequently, Buyer shall have the right, in addition to any other rights it may have, to obtain, in any court of competent jurisdiction, injunctive relief to restrain any breach or threatened breach of any provision of this Article 6 or otherwise to specifically enforce any of the provisions hereof, and Buyer shall not be obligated to post a bond or other security in seeking such relief. This remedy is in addition to damages directly or indirectly suffered by Buyer and reasonable attorney’s fees.

6.3 Independent Covenant. All of the covenants contained in this Article 6 shall be construed as an agreement independent of any other provision of this Agreement, and the existence of any claim or cause of action of the Restricted Parties against Buyer, whether predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by Buyer or the Company of such covenants.

6.4 Materiality and Enforceability. The Restricted Parties each agree that the covenants contained in this Article 6 are a material and substantial part of this transaction. The Parties agree that a portion of the consideration paid by Buyer pursuant to this Agreement is in exchange for the covenants contained in this Article 6, and therefore, the duration and area for which the covenants in this Article 6 are to be effective are reasonable. In the event that any court finally determines that the time period or the geographic scope of any such covenant is unreasonable or excessive and any covenant is to that extent made unenforceable, the Parties agree that the restrictions of this Article 6 shall remain in full force and effect for the greatest time period and within the greatest geographic area that would not render it unenforceable. The Parties intend that each of the covenants in Article 6 shall be deemed to be a separate covenant.

7. SURVIVAL OF COVENANTS, REPRESENTATIONS AND WARRANTIES; INDEMNIFICATION

7.1 Survival of Covenants, Representations, and Warranties.

(a) Except as set forth below in respect of certain representations and warranties of Sellers (as defined in Article 3) and the Companies, the covenants, representations and warranties of the Parties contained in this Agreement shall survive the Closing hereunder and continue in full force and effect for the longer of (a) ***, or (b) the date upon which the liability to which any such claim may relate is barred by all applicable statutes of limitation, taking into account any extensions or waivers thereof, and thereafter shall terminate (“Expiration Date”). Notwithstanding the foregoing, the indemnification obligations for any misrepresentations contained in Sections 3.1, 3.2, 3.3, and 3.21 survive the Closing hereunder and continue in full force and effect for so long as Buyer is obligated to pay the Variable Purchase Price pursuant to Section 2.2 herein. Notwithstanding the foregoing or anything to the contrary contained herein, in the event of a merger, consolidation, combination, liquidation or cessation of the business or operations of any Company (“Termination Event”), the Expiration Date shall be deemed to have occurred on the effective date of the Termination Event with respect to such Company.

(b) No Party shall be obligated to indemnify any other Party pursuant to this Article 7 for any claim that is first made after the Expiration Date. Claims first made prior to the Expiration Date shall be subject to indemnity pursuant to this Article 7

throughout the entirety of the Proceeding or Proceedings arising out of such claim, notwithstanding the fact that such Proceeding or Proceedings may extend beyond the Expiration Date.

7.2 Indemnification by Sellers. For claims for indemnification made under this Section 7.2, for events or circumstances arising out of the period prior to Closing, Sellers will, from and after Closing and during the period prior to the Expiration Date, jointly and severally, unconditionally, absolutely and irrevocably agree to and shall defend, indemnify and hold harmless Buyer and each of Buyer’s subsidiaries, shareholders, affiliates, officers, directors, employees, counsel, accountants, agents, successors, assigns, heirs and legal and personal representatives (Buyer and all such persons or entities are collectively referred to as “Buyer’s Indemnified Persons”) from and against, and shall reimburse Buyer’s Indemnified Persons for, each and every Loss paid, imposed on or incurred by Buyer’s Indemnified Persons, directly or indirectly, relating to, resulting from or arising out of: (a) any inaccuracy in any representation or warranty of any Company or Sellers under this Agreement, or the Schedules hereto, or any breach or nonfulfillment of any covenant, agreement or other obligation of any Seller or of such Company under this Agreement or any agreement or document delivered pursuant hereto; (b) all Environmental Claims arising with respect to facts, conditions, events, operations and circumstances existing solely prior to the Closing Date; provided, however, that in the event of any Environmental Claim that arises with respect to facts, conditions, events, operations and circumstances arising both before and after the Closing Date, Seller’s indemnification obligation shall be limited to such matters arising with respect to facts, conditions, events, operations and circumstances prior to the Closing Date; and (c) the Retained Liabilities. Each such Loss is hereinafter referred to as a “Seller Indemnifiable Claim”.

7.3 Indemnification by Buyer. For claims for indemnification made under this Section 7.2, for events or circumstances arising out of the period after the Closing Date, Buyer unconditionally, absolutely and irrevocably agrees to and shall defend, indemnify and hold harmless the Sellers and their counsel, accountants, agents, contractors, successors, assigns, heirs and legal and personal representatives (the Sellers and such persons are collectively referred to as the “Sellers’ Indemnified Persons”) from and against, and shall reimburse the Sellers’ Indemnified Persons for, each and every Loss paid, imposed on or incurred by the Sellers’ Indemnified Persons, directly or indirectly, relating to, resulting from or arising out of (a) any inaccuracy in any representation or warranty of Buyer under this Agreement, whether or not Sellers’ Indemnified Persons relied thereon or had knowledge thereof, or any breach or nonfulfillment of any covenant, agreement or other obligation of Buyer under this Agreement or any agreement or document delivered pursuant hereto; (b) all liabilities of the Companies arising after the Closing Date that are not attributable to the period of time prior to the Closing Date, including, but not limited to claims, demands and causes of action against any Company and/or Buyer arising from or related to the ownership or operation of the Companies after the Closing Date, (c) all Environmental Claims arising with respect to facts, conditions, events, operations and circumstances arising solely after the Closing Date; provided, however, that in the event of any Environmental Claim that arises with respect to facts, conditions, events, operations and circumstances arising both before and after the Closing Date, Buyer’s indemnification obligation shall be limited to such matters arising with respect to facts, conditions, events, operations and circumstances after the Closing Date; and (d) any other facts

or circumstances in any manner relating to the period after the Closing Date. Each such Loss is hereinafter referred to as a “Buyer Indemnifiable Claim”.

7.4 Notice and Defense of Third Party Claims. If any Proceeding shall be brought or asserted under this Article 7 against an indemnified party or any successor thereto (the “Indemnified Person”) in respect of which indemnity may be sought under this Article 7 from an indemnifying person or any successor thereto (the “Indemnifying Person”), the Indemnified Person shall give prompt written notice of such Proceeding to the Indemnifying Person who shall assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Person and the payment of all expenses; provided, that any delay or failure to so notify the Indemnifying Person shall relieve the Indemnifying Person of its obligations hereunder only to the extent, if at all, that it is prejudiced by reason of such delay or failure. In no event shall any Indemnified Person be required to make any expenditure or bring any cause of action to enforce the Indemnifying Person’s obligations and liability under and pursuant to the indemnifications set forth in this Article 7. In addition, the filing of a Proceeding shall not be required as a condition or prerequisite to the Indemnifying Person’s obligations under this Article 7, if the Indemnified Person is required to expend sums for investigation or remedial purposes as a result of a threatened Proceeding. The Indemnified Person shall have the right to employ separate counsel in any of the foregoing Proceedings and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the Indemnified Person unless the Indemnified Person shall in good faith determine that there exist actual or potential conflicts of interest which make representation by the same counsel inappropriate. The Indemnified Person’s right to participate in the defense or response to any Proceeding should not be deemed to limit or otherwise modify its obligations under this Article 7. In the event that the Indemnifying Person, within 15 days after notice of any such Proceeding, fails to assume the defense thereof, the Indemnified Person shall have the right to undertake the defense, compromise or settlement of such Proceeding for the account of the Indemnifying Person, subject to the right of the Indemnifying Person to assume the defense of such Proceeding with counsel reasonably satisfactory to the Indemnified Person at any time prior to the settlement, compromise or final determination thereof. Anything in this Article to the contrary notwithstanding, the Indemnifying Person shall not, without the Indemnified Person’s prior written consent, settle or compromise any Proceeding or consent to the entry of any judgment with respect to any Proceeding for anything other than money damages paid by the Indemnifying Person. The Indemnifying Person may, without the Indemnified Person’s prior written consent, settle or compromise any such Proceeding or consent to entry of any judgment with respect to any such Proceeding that requires solely the payment of money damages by the Indemnifying Person and that includes as an unconditional term thereof the release by the claimant or the plaintiff of the Indemnified Person from all liability in respect of such Proceeding.

7.5 Insurance, Payment and Interest. The amount of any Loss for which an Indemnified Person shall seek indemnification under this Article 7 shall be reduced by (a) the amount of any insurance proceeds paid to the Indemnified Person arising out of the event giving rise to the claim, and (b) the cash benefit inuring to the Indemnified Person as a result of any federal, state or local tax claim made by such Indemnified Person which tax claim arises out of the Loss. The Indemnifying Person shall make any payment required to be made under this Section 7.5 in immediately available funds and on demand. Any amounts or payments required to be paid by an Indemnifying Person under this Section 7.5 which are not paid within fifteen

(15) business days of receipt by the Indemnifying Person of the Indemnified Person’s demand therefor shall thereafter be deemed delinquent, and the Indemnifying Person shall pay to the Indemnified Person immediately upon demand, interest at the lesser of eight percent (8%) per annum or the highest amount allowed by Oklahoma law, from the date such payment becomes delinquent to the date of payment of such delinquent sums.

7.6 Buyer’s Right of Withholding and Offset.

(a) Upon a final determination (by a court of competent jurisdiction or by agreement of Buyer and Sellers) of the value of any Seller Indemnifiable Claim, Buyer shall be entitled to an immediate offset and credit against the unpaid payments hereunder (an “Offset”) in an aggregate amount equal to the value of such Seller Indemnifiable Claim, subject to and in accordance with the provisions of Section 7.8(a).

(b) Notwithstanding (a) above, Sellers agree that Buyer may, without further action, immediately Offset any amounts for which Buyer or any Company may be found liable in any Proceeding or settlement (over and above such proceeds as may be paid by insurance, if any), arising out of the Accident referred to in Section 3.31 herein to the extent such amounts are not paid by Sellers pursuant to Section 7.5. In such event, the amounts permitted to be offset shall include all sums due pursuant to Section 7.5 arising out of the Accident.

7.7 NEGLIGENCE AND STRICT LIABILITY. WITHOUT LIMITING OR ENLARGING THE SCOPE OF THE INDEMNIFICATION OBLIGATIONS SET FORTH IN THIS AGREEMENT, THE PARTIES HERETO SHALL BE ENTITLED TO INDEMNIFICATION IN ACCORDANCE WITH THE TERMS HEREOF, REGARDLESS OF WHETHER THE LOSS OR CLAIM GIVING RISE TO SUCH INDEMNIFICATION OBLIGATION IS THE RESULT OF THE STRICT LIABILITY OF THE PARTY INDEMNIFIED. THE INDEMNIFIED PARTY SHALL BE ENTITLED TO INDEMNIFICATION WITH RESPECT TO LOSSES OR CLAIMS ARISING IN PART FROM THE NEGLIGENCE OF THE INDEMNIFIED PARTY; PROVIDED THAT THE INDEMNIFIED PARTY SHALL NOT BE ENTITLED TO INDEMNIFICATION FOR THAT PERCENTAGE OF A LOSS OR CLAIM ATTRIBUTABLE TO THE INDEMNIFIED PARTY’S NEGLIGENCE. THE PARTIES AGREE THAT THIS PARAGRAPH CONSTITUTES A CONSPICUOUS LEGEND.

7.8 Limits of Liability.

(a) Except as set forth in (b) below, the liability of the Sellers to the Buyer, or of the Buyer to the Sellers, under this Agreement shall not exceed *** (the “Cap”). No such party shall be obligated to provide indemnification under this Agreement for any damage until the aggregate indemnifiable Damages exceed *** (the “Threshold”). Upon a party’s aggregate indemnifiable Damages reaching the Threshold, all such Damages (including the first ***) shall be subject to indemnification.

(b) Notwithstanding the limits set forth in (a) above, Sellers’ indemnity obligations hereunder shall not be subject to the Threshold and shall not be limited to the Cap with respect to (i) any obligations of Buyer or any of the Companies (including all

subsidiaries thereof) to pay Taxes for any period ending on or prior to the Closing Date, and (ii) any obligations of Buyer or any of the Companies to pay any sums to any person, which obligations arise out of or are in connection with the Accident.

13.8 Section Headings. The section headings contained in this Agreement are inserted for convenience of reference only and shall not affect the meaning or interpretation of this Agreement.

13.9 Severability. If for any reason whatsoever, any one or more of the provisions hereof shall be held or deemed to be illegal, inoperative, unenforceable or invalid as applied to any particular case or in all cases, such circumstances shall not have the effect of rendering such provision illegal, inoperative, unenforceable or invalid in any other case or of rendering any of the other provisions hereof illegal, inoperative, unenforceable or invalid. Furthermore, in lieu of each such illegal, invalid, unenforceable or inoperative provision, there shall be added automatically,

as part of this Agreement, a provision similar in terms of such illegal, invalid, unenforceable or inoperative provision as may be possible and as shall be legal, valid, enforceable and operative.

13.10 Drafting. The parties acknowledge and confirm that they and/or their respective attorneys have participated jointly in the review and revision of this Agreement and that it has not been written solely by any one party or counsel for any one party. The parties therefore stipulate and agree that the rule of construction to the effect that any ambiguities are to be or may be resolved against the drafting party shall not be employed in the interpretation of this Agreement to favor any party against another.

13.11 References. The use of the words “hereof,” “herein,” “hereunder,” “herewith,” “hereto,” “hereby,” and words of similar import shall refer to this entire Agreement, and not to any particular article, section, subsection, clause, or paragraph of this Agreement, unless the context clearly indicates otherwise.

13.15 No Implied Covenants. Each party, against the other, waives and relinquishes any right to assert, either as a claim or as a defense, that any other party is bound to perform or liable for the nonperformance of any implied covenant or implied duty or implied obligation.

13.16 Indirect Action. Where any provision hereof refers to action to be taken by any person or party, or which such person or party is prohibited from taking, such provision shall be applicable whether the action in question is taken directly or indirectly by such person or party.

The prevailing party in any dispute between the parties arising out of the interpretation, application or enforcement of any provision hereof shall be entitled to recover all of its reasonable attorneys’ fees and costs whether suit be filed or not, including without limitation costs and attorneys’ fees related to or arising out of any trial or appellate proceedings.
