ARTICLE 3

CERTAIN TITLE AND ENVIRONMENTAL MATTERS

3.1Sellers’ Title.

(a)General Disclaimers. The provisions of thisArticle 3, the special warranty of Defensible Title in the Assignment and Bill of Sale and the condition to closing inSection 7.3(b) provide Purchaser’s exclusive remedy with respect to any Title Defects, title encumbrances or any failure of title with respect to any Assets.

(b) The Assignment and Bill of Sale to be executed and delivered by the Parties at Closing shall be in the forms attached asExhibit B-1 andExhibit B-2, and shall contain a special warranty of Defensible Title to the Leases shown onExhibit A-1 by, through, and under the applicable Seller, but not otherwise, subject to the Permitted Encumbrances.

(c) As used in thisArticle 3, the “applicable Seller” or “applicable Sellers” and similar terms mean the Seller or Sellers that own an interest in the Property affected by a particular Defect or Title Benefit.

25

(d) Special Warranties of Title in the Assignment and Bill of Sales.

(i) The Assignment and Bill of Sale delivered at Closing shall contain a special warranty of Defensible Title by each Seller whereby each Seller warrants Defensible Title to its interest in the Properties unto Purchaser against every Person whomsoever lawfully claims the same or any part thereof by, through or under such Seller but not otherwise, subject, however, to the Permitted Encumbrances. All special warranties of Defensible Title contained in the Assignment and Bill of Sale shall be subject to the further limitations and provisions of thisArticle 3,provided that the Individual Claim Threshold and the Defect Deductible shall not apply to any claims for breach of the special warranty of Defensible Title.

(ii) As a condition to asserting a valid claim for breach of a Seller’s special warranty of Defensible Title set forth in the Assignment and Bill of Sale, no later than the date twelve (12) months after the Closing Date, Purchaser may furnish to such Seller a Title Defect Notice meeting the requirements ofSection 3.6(a) setting forth any matters which Purchaser asserts as a breach of the special warranty of Defensible Title set forth in the Assignment and Bill of Sale. Such Seller shall have a reasonable opportunity, but not the obligation, to cure prior to the date sixty (60) days after such notice is delivered to such Seller any breach of the special warranty of Defensible Title set forth in the Assignment and Bill of Sale. Purchaser agrees to reasonably cooperate with any attempt by such Seller to cure any such breach of the special warranty of Defensible Title set forth in the Assignment and Bill of Sale. Purchaser shall be deemed to have waived all breaches of a Seller’s special warranty of Defensible Title set forth in such Seller’s Assignment and Bill of Sale for which such Seller has not received on or before the date twelve (12) months after the Closing Date a valid Title Defect Notice that satisfies the requirements set forth inSection 3.6(a). Purchaser shall be deemed to have waived any breaches of a Seller’s special warranty of Defensible Title that Purchaser had Knowledge of as of the Defect Claim Time and did not assert as a Title Defect by the Defect Claim Date pursuant to the procedures in thisArticle 3.

(iii) For purposes of the special warranties of Defensible Title contained in the Assignment and Bill of Sale, the value of the Assets set forth in the exhibits thereto, as applicable, shall be deemed to be the Allocated Value thereof, as adjusted herein. Recovery from any Seller on the special warranties of Defensible Title contained in the Assignment and Bill of Sale shall be limited to an amount (without any interest accruing thereon) equal to the reduction in the Unadjusted Purchase Price of such Seller to which Purchaser would have been entitled had Purchaser asserted the Title Defect giving rise to such breach of the special warranty of Defensible Title of such Seller contained in the Assignment and Bill of Sale, as applicable, as a Title Defect prior to Closing pursuant toSection 3.6(a), but in each case not taking into account the Individual Claim Threshold and the Defect Deductible of such Seller.

(b) With respect to each Property affected by Title Benefits reported underSection 3.8 (b), the Unadjusted Purchase Price of the applicable Seller shall be increased by an amount (the “Title Benefit Amount”) determined pursuant toSection 3.9(b), but only to the extent of the aggregate amount of the reductions in the Unadjusted Purchase Price of such Seller attributable to Title Defects, it being acknowledged and agreed that Title Benefit Amounts may only be applied to offset the amount of such reductions in the Unadjusted Purchase Price of such Seller attributable to Title Defects.

(c) Subject to thisArticle 3, the special warranty of Defensible Title as set forth in the Assignment and Bill of Sale with respect to the Assets, the representations and warranties inSection 4.10, each Seller’s obligations inSection 11.2(e) and Purchaser Parties’ indemnity rights with respect thereto, and the condition to the Purchaser Parties’ obligation to Close underSection 7.3(b), and without limiting Purchaser’s remedies for Defects set forth in thisArticle 3,NO SELLER MAKES, AND PURCHASER, ON BEHALF OF ITSELF AND EACH MEMBER OF THE PURCHASER GROUP, HEREBY WAIVES, RELEASES AND DISCHARGES EACH MEMBER OF THE SELLER GROUP FROM, ANY WARRANTY OR REPRESENTATION OF ANY MEMBER OF THE SELLER GROUP, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, WITH RESPECT TO (I) ANY SELLER’S OR ANY OTHER PERSON’S TITLE TO ANY OF THE ASSETS, (II) ANY MATTERS WITH RESPECT TO THE EXISTENCE OF ANY ENVIRONMENTAL DEFECT, ENVIRONMENTAL LIABILITIES, ANY RELEASE OF HAZARDOUS MATERIALS OR ANY OTHER ENVIRONMENTAL CONDITION WITH RESPECT TO THE OWNERSHIP, USE OR OPERATION OF ASSETS, OR (III) WHETHER ANY SELLER OR ANY OF THE ASSETS OF SUCH SELLER (OR THE OWNERSHIP, USE OR OPERATION THEREOF) ARE IN COMPLIANCE WITH ANY ENVIRONMENTAL LAW.

37

Assignment and Bill of Sale, the representations and warranties inSection 4.10, each Seller’s obligations inSection 11.2(e) and Purchaser Parties’ indemnity rights with respect thereto, and the condition to the Purchaser Parties’ obligation to Close underSection 7.3(b), thisArticle 3 sets forth Purchaser’s sole and exclusive remedy with respect to (A) any Defect, (B) the failure of any Seller or any other Person to have title to any of the Assets (whether Defensible Title or otherwise), and (C) the existence of any Environmental Defect, Environmental Liabilities, Release of Hazardous Materials or any other environmental condition or activity with respect to the Assets.Subject to the representations and warranties inSection 4.10 and each Seller’s obligations underSection 11.2(e), and their related indemnity obligation, further, Purchaser on its own behalf and on behalf of the Purchaser Group, hereby releases, remises, and forever discharges Sellers, the Seller Group, and their respective Affiliates from any right of contribution or cost recovery that Purchaser may have at common law or under Environmental Laws, including CERCLA, RCRA and the Texas Solid Waste Disposal Act, all as amended.

3.9Calculation of Title and Environmental Defect Amounts and Title Benefit Amounts.

(a) The Title Defect Amount resulting from a Title Defect shall be determined as follows:

(i) if Purchaser and the applicable Seller agree in writing upon the Title Defect Amount, that amount shall be the Title Defect Amount;

(ii) if the Title Defect is a Lien which will not otherwise be released at Closing and which is liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to unconditionally remove the Title Defect from the applicable Seller’s (and Purchaser’s as successor in interest to such Seller) interest in the affected Property, not to exceed, however, the Allocated Value of such Seller’s interest in the affected Property;

(iii) if a Title Defect as to any Well represents a negative discrepancy between (A) the actual Net Revenue Interest of the applicable Seller for any such Property and (B) the “Net Revenue Interest” percentage stated for such Seller onExhibit A-2 as to such Property, then the Title Defect Amount shall be equal to (1) the product of the Allocated Value of such Seller’s interest as to such Propertymultiplied by (2) a fraction, the numerator of which is (x) the remainder of (I) the “Net Revenue Interest” percentage stated onExhibit A-2 for such Seller’s interest as to such Propertyminus (II) the actual Net Revenue Interest of such Seller as to such Property, and the denominator of which is (y) the “Net Revenue Interest” percentage stated onExhibit A-2 for such Seller’s interest as to such

38

Property;provided that if the Title Defect does not affect the “Net Revenue Interest” percentage stated onExhibit A-2 for such Seller’s interest as to such Property throughout its entire productive life, the Title Defect Amount determined under thisSection 3.9(a)(iii) shall be reduced to take into account the applicable time period only;

(iv) if a Title Defect as to any Undeveloped Lease represents a negative discrepancy between (A) the actual aggregate Net Revenue Interest of the applicable Seller in all Undeveloped Leases included in any PLSS Section listed onSchedule 3.4 and (B) the Specified NRI, then the Title Defect Amount shall be equal to (1) the product of the Net Mineral Acre Price thereof,multiplied by (2) the aggregate number of Net Mineral Acres of such Seller’s interest as to all Undeveloped Leases included in such PLSS Sectionmultiplied by (3) a fraction, the numerator of which is (x) the remainder of (I) the Specified NRIminus (II) the actual aggregate Net Revenue Interest for such Seller’s interest in all Undeveloped Leases included in any PLSS Section listed onSchedule 3.4 and the denominator of which is (y) the Specified NRI;provided that if the Title Defect does not affect the Specified Interest for such Seller’s interest as to such Property throughout its entire productive life, the Title Defect Amount determined under thisSection 3.9(a)(iv) shall be reduced to take into account the applicable time period only;

(v) if a Title Defect constitutes a reduction in the aggregate number of Net Mineral Acres as to the applicable Seller’s interest in all Undeveloped Leases included in any PLSS Section listed onSchedule 3.4, then the Title Defect Amount for such Title Defect shall be equal to the product of (A) the Net Mineral Acre Price thereforemultiplied by (B) the remainder of (1) the number of Net Mineral Acres set forth onSchedule 3.4 purported to be included in such Seller’s interest in all Undeveloped Leases included in such PLSS Sectionminus (2) the actual aggregate number of Net Mineral Acres included in such Seller’s interest in all Undeveloped Leases included in such PLSS Section after giving effect to such Title Defect;

(vi) if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the affected Property of a type not described inSections 3.9(a)(i) through3.9(a)(v), the Title Defect Amount shall be determined by taking into account the Allocated Value of the applicable Seller’s interest as to the Property so affected, the portion of the applicable Seller’s interest as to the Property affected by the Title Defect, the legal effect of the Title Defect, the potential present value economic effect of the Title Defect over the life of the affected Property, the values placed upon the Title Defect by Purchaser and the applicable Seller, and such other factors as are necessary to make an evaluation and determination of such value;

39

(vii) the Title Defect Amount with respect to a Title Defect shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder, to the extent such costs or losses generate an adjustment to the Unadjusted Purchase Price of the applicable Seller;

(viii) if a Title Defect is reasonably susceptible of being cured, the Title Defect Amount with respect to any Title Defect shall in no event be greater than the amount that can reasonably be shown to be the reasonably estimated present value (discounted ten percent (10%)) of lowest-cost response over time (determined as of the Closing Date) to cure such Title Defect; and

(ix) notwithstanding anything to the contrary in thisArticle 3:

(A) a valid individual claim (or series of related claims) for a Title Defect for which a Title Defect Notice is given prior to the Defect Claim Time shall only generate an adjustment to the Unadjusted Purchase Price of the applicable Seller under thisArticle 3 if the Title Defect Amount with respect thereto exceeds the Individual Claim Threshold;

(B) if the aggregate asserted Title Defect Amounts attributable to the effects of all asserted Title Defects upon any given Property shall exceed 25% of Allocated Value of such Property, then the applicable Seller or Sellers may, at its or their election (as the case may be) and by written notice to Purchaser no later than two (2) Business Days prior to the Closing, cause such Seller(s) interest in such Property to be excluded from this Agreement, in which case, Seller(s) interest in such affected Property shall constitute an Excluded Asset, Seller(s) interest in such affected Property shall be deemed to have been deleted fromExhibits A-1 andA-2 andSchedule 3.4 hereto, and the Unadjusted Purchase Price of the applicable Seller shall be reduced by the Allocated Value of such Seller’s interest in such Property. In the event any Seller elects to treat a given Property as an Excluded Asset due to the aggregate of all Title Defects asserted by Purchaser against such Property, such Seller shall make such election and provide written notice of the same to Purchaser no later than five (5) Business Days prior to the Closing Date;

40

(C) with respect to each Seller, there shall be no adjustment to the Unadjusted Purchase Price of such Seller for Title Defects unless the aggregate amount of Title Defect Amounts of all valid Title Defects affecting the Assets of such Seller where the Title Defect Amount thereof exceeds the Individual Claim Threshold exceeds the Title Defect Deductible, and then only to the extent such aggregate amount exceeds the Title Defect Deductible of such Seller; and

(D) a Title Defect Amount for any Seller may not exceed the Allocated Value of interest of such Seller in the affected Properties or Assets.

(b) The Title Benefit Amount resulting from a Title Benefit shall be determined as follows:

(i) if Purchaser and the applicable Seller agree in writing upon the Title Benefit Amount, that amount shall be the Title Benefit Amount;

(ii) if a Title Benefit as to any Well represents a positive discrepancy between (A) the actual Net Revenue Interest of the applicable Seller in any such Property and (B) the Net Revenue Interest set forth onExhibit A-2 for such Property, then the Title Benefit Amount shall be equal to (A) the product of the Allocated Value of such Seller’s interest in such Propertymultiplied by (B) a fraction, the numerator of which is (1) the remainder of (x) the actual Net Revenue Interest of such Seller in such Wellminus (y) the “Net Revenue Interest” percentage stated onExhibit A-2 for such Seller’s interest in such Well, and the denominator of which is (2) the “Net Revenue Interest” percentage stated onExhibit A-2 for such Seller’s interest in such Well;provided that if the Title Benefit does not affect the Net Revenue Interest for such Seller’s interest in such Well throughout its entire productive life, the Title Benefit Amount determined under thisSection 3.9(b)(ii) shall be reduced to take into account the applicable time period only;

(iii) if a Title Benefit as to any Undeveloped Lease represents a positive discrepancy between (A) the aggregate actual Net Revenue Interest in all Undeveloped Leases included in such PLSS Section listed onSchedule 3.4 and (B) the Specified NRI, then the Title Benefit Amount shall be equal to (1) the product of the Net Mineral Acre Price thereof,multiplied by (2) the aggregate number of Net Mineral Acres of such Seller’s interest in all Undeveloped Leases included in such PLSS Sectionmultiplied by (3) a fraction, the numerator of which is (x) the remainder of the actual aggregate Net Revenue Interest for such Seller’s interest in all Undeveloped Leases included in such PLSS Section after giving effect to such Title Benefitminus the Specified NRI and the denominator of which is (y) the Specified NRI;provided that if the Title Benefit does not affect the

41

Net Revenue Interest for such Seller’s interest in such Undeveloped Lease throughout its entire productive life, the Title Benefit determined under thisSection 3.9(b)(iii) shall be reduced to take into account the applicable time period only;

(iv) if a Title Benefit constitutes an increase in the aggregate number of Net Mineral Acres of such Seller’s interest in all Undeveloped Leases included in a PLSS Section, then the Title Benefit Amount for such Title Benefit shall be equal to the product of (A) the Net Mineral Acre Price thereforemultiplied by (B) the remainder of (1) the actual aggregate number of Net Mineral Acres included in such Seller’s interest in all such Undeveloped Leases included in such PLSS Section after giving effect to such Title Benefitminus (2) the number of Net Mineral Acres purported to be included in such Seller’s interest in the aggregate number of Net Mineral Acres of such Seller’s interest in all Undeveloped Leases included in such PLSS Section as set forth onSchedule 3.4;

(v) if the Title Benefit represents a benefit of a type not described inSection 3.9(b)(i) throughSection 3.9(b)(iv), the Title Benefit Amount shall be determined by taking into account the Allocated Value of the applicable Seller’s interest in such Property so affected by the Title Benefit, the portion of the applicable Seller’s interest in such Property affected by the Title Benefit, the legal effect of the Title Benefit, the present value economic effect of the Title Benefit over the life of the affected Property, the values placed upon the Title Benefit by Purchaser and such Seller, and such other factors as are necessary to make an evaluation and determination of such value;

(vi) the Title Benefit Amount with respect to a Title Benefit shall be determined without duplication of any benefits or gains included in another Title Benefit Amount or adjustment to the Unadjusted Purchase Price of the applicable Seller; and

(vii) notwithstanding anything to the contrary in thisArticle 3, in the event that any valid Title Benefit is not waived in writing by the applicable Seller, then, subject to Purchaser’s right to dispute the existence of such Title Benefit and the Title Benefit Amount asserted with respect thereto, then the Unadjusted Purchase Price of such Seller shall be increased by the sum of the aggregate Title Benefit Amounts attributable all such Title Benefits, but only to the extent of the aggregate amount of the reductions in the Unadjusted Purchase Price of such Seller attributable to Title Defects, it being acknowledged and agreed that Title Benefit Amounts may only be applied to offset the amount of such reductions in the Unadjusted Purchase Price of such Seller attributable to Title Defects.

42

(c) The Environmental Defect Amount resulting from an Environmental Defect shall be determined as follows:

(i) if Purchaser and the applicable Seller agree on the Environmental Defect Amount, that amount shall be the Environmental Defect Amount;

(iii) the Environmental Defect Amount with respect to an Environmental Defect shall be determined without duplication of any costs or losses included in another Environmental Defect Amount or adjustment to the Unadjusted Purchase Price of the applicable Seller; and

(iv) notwithstanding anything to the contrary in thisArticle 3:

(A) an individual claim for an Environmental Defect with respect to an individual Property or Asset shall only generate an adjustment to the Unadjusted Purchase Price of the applicable Seller if the Environmental Defect Amount at that Property or Asset exceeds the Individual Claim Threshold;

(B) if the aggregate Environmental Defect Amounts attributable to the effects of all Environmental Defects upon any given Property shall exceed 25% of Allocated Value of such Property, then Purchaser, or the applicable Seller or Sellers may, at its or their election (as the case may be) and by written notice to Purchaser, in the case of any Seller making such notice, or the applicable Seller or Sellers in the case of Purchaser making such notice, no later than two (2) Business Days prior to the Closing, cause such Seller’s or Sellers’ interest in such Property to be excluded from this Agreement, in which case, such Seller’s or

43

Sellers’ interest in such affected Property shall constitute an Excluded Asset, such Seller’s or Sellers’ interest in such affected Property shall be deemed to have been deleted fromExhibits A-1 andA-2 andSchedule 3.4 hereto, and the Unadjusted Purchase Price of the applicable Seller or Sellers shall be reduced by the Allocated Value of such Seller’s or Sellers’ interest in such Property.

(C) with respect to each Seller, there shall be no adjustment to the Unadjusted Purchase Price of such Seller for Environmental Defects unless the aggregate amount of Environmental Defect Amounts of all valid Environmental Defects affecting the Assets of such Seller where the Environmental Defect Amounts exceeds the Individual Claim Threshold, exceeds the Environmental Defect Deductible of such Seller, and then only to the extent such aggregate amount exceeds the Environmental Defect Deductible of such Seller.

3.10Dispute Resolution.

Purchaser (at no cost to Purchaser) shall cooperate with any reasonable request made by any Seller with respect to obtaining such consents, approvals, permissions, and waivers.

3.12Consent Requirements.

(a) Each Seller shall deliver a written notice to Purchaser two (2) Business Days before Closing setting forth each of such Seller’s Required Consent which, as of such date, has not been satisfied or waived. In no event shall there be transferred at Closing any Asset for which a Required Consent has not been satisfied, waived or obtained, other than Customary Consents.

(b) In cases in which the Asset of a Seller subject to such an unobtained Required Consent is an Asset other than a Property, and Purchaser is assigned the Property or Properties to which such Asset relates, but such Asset is not transferred to Purchaser due to the unwaived Required Consent requirement, Purchaser and such Seller shall continue after Closing to use commercially reasonable efforts to obtain the Required Consent so that such Asset can be transferred to Purchaser upon receipt of the Required Consent , and, (i) there shall be no downward adjustment to the Unadjusted Purchase Price of such Seller relative to such Asset, (ii) if permitted pursuant to applicable Law and agreement, such Asset shall be held by such Seller for the benefit of Purchaser, (iii) Purchaser shall pay all amounts and liabilities due thereunder or with respect thereto (and Purchaser agrees to indemnify, defend and hold harmless such Seller with regard thereto), and (iv) Purchaser shall be responsible for the performance of any obligations under or with respect to such Asset.

(c) In cases in which the Asset of a Seller subject to such a Required Consent requirement is a Property and the third-Person consent to the transfer of such Property is not obtained by Closing, such Property shall be deemed deleted fromExhibits A-1 andA-2 and shall constitute an Excluded Asset (subject to thisSection 3.12(c)), and the Unadjusted Purchase Price of the applicable Seller shall be reduced by the Allocated Value of such Property. If any such Required Consent is subsequently satisfied prior to the date of the final adjustment to the Unadjusted Purchase Price of such Seller underSection 8.5, such Seller shall be reimbursed in that final adjustment for the amount of any previous deduction from such Seller’s

48

Unadjusted Purchase Price, the relevant Property shall be transferred, and the provisions of thisSection 3.12 shall no longer apply to such Required Consent requirement. If such Required Consent requirement is not satisfied prior to the date of the final adjustment to the Unadjusted Purchase Price of such Seller underSection 8.5, subject to the remainder of thisSection 3.12, the affected Property shall be deemed to have been permanently deleted fromExhibits A-1 andA-2 hereto and shall constitute an Excluded Asset.

(d) Notwithstanding anything to the contrary herein, Purchaser may (but shall not be obligated to) request, at any time prior to the final determination of the Final Purchase Price of the applicable Seller pursuant toSection 8.5, that such Seller transfer to Purchaser any Asset not transferred at Closing due to an unsatisfied or unwaived Required Consent. Promptly after receipt of such a request, such Seller shall, pursuant to an assignment and bill of sale substantially in the form attached hereto asExhibit B, convey to Purchaser, effective as of the Effective Date, the affected Asset; and such Seller shall simultaneously with the delivery of the conveyance (and as a condition precedent to delivery of the conveyance) be reimbursed in the final adjustment of such Seller’s Unadjusted Purchase Price for the amount of any previous deduction from the Unadjusted Purchase Price of such Seller; and Purchaser shall defend, indemnify, and hold each member of the Seller Group harmless from and against all Damages arising from the conveyance of such Asset without the satisfaction or waiver of the Required Consent requirement.

3.13Preferential Purchase Rights.

(a) Any preferential purchase right must be exercised subject to all terms and conditions set forth in this Agreement, including the successful Closing of this Agreement pursuant toArticle 8 on the dates certain set forth herein. The consideration payable under this Agreement for any particular Asset for purposes of preferential purchase right notices shall be the Allocated Value for such Asset, adjusted as set forth in this Agreement.

(b) If any preferential right to purchase any Asset of any Seller is validly exercised prior to Closing or the time for exercising a preferential purchase right has not expired as of the Closing, the Asset (or portions thereof) affected thereby shall constitute an Excluded Asset and the Unadjusted Purchase Price of such Seller shall be decreased by the Allocated Value of the affected Asset, and the affected Asset shall not be transferred at Closing and shall constitute an Excluded Asset.

49

(c) In the event that a preferential purchase right with respect to an Asset deleted and excluded from the transactions contemplated by this Agreement at Closing pursuant toSection 3.13(b) is later waived prior to acquisition from the applicable Seller or the time for exercising such preferential purchase right expires without exercise, then:

(i) Purchaser shall, subject to its conditions precedent inSections 7.3(a) and7.3(b), purchase the affected Asset (or portion thereof) on the terms set forth in this Agreement at a delayed closing which shall occur within ten (10) Business Days following the date on which the applicable Seller obtains such waiver, or the time period for exercising the applicable preferential right has expired (which date shall, with respect to such Asset, or portion thereof, be considered to be the Closing Date); and

(ii) Unadjusted Purchase Price adjustments calculated in the same manner as the adjustments inSection 2.2 with respect to the affected Asset (or portion thereof), if any, shall be calculated from the period from and after the Effective Date to the date of the conveyance, and the net amount of such adjustment, if positive, shall be paid by Purchaser to the applicable Seller, and, if negative, by the applicable Seller to Purchaser.

(d) Purchaser acknowledges that each Seller desires to sell all of its Assets and would not have entered into this Agreement but for Purchaser’s agreement to purchase all of the Assets as herein provided and subject to all the terms hereof. Accordingly, it is expressly understood and agreed that no Seller desires to sell any Assets subject to any validly exercised preferential right to purchase unless the sale of all Assets subject to a validly exercised preferential right to purchase occurs at the same time that the sale of the Assets contemplated hereunder is consummated. Subject to the terms hereunder and in furtherance of the foregoing, in the event that this Agreement is terminated prior to Closing, then all obligations and rights hereunder with respect to any Assets subject to preferential rights to purchase shall be void and of no force or effect.

(e) At any Seller’s request, Purchaser shall provide reasonable access to Purchaser’s and its Affiliates’ personnel who have knowledge of the information described in thisSection 9.2.

9.3Tax Deferred Exchange.

(a) The Parties agree that any Seller and/or Purchaser may elect to treat the acquisition or sale of the Assets as an exchange of like-kind property under Section 1031 of the Code (an “Exchange”),provided that the Closing shall not be delayed by reason of the Exchange. Each applicable Party agrees to use reasonable efforts to cooperate with the other applicable Party in the completion of such an Exchange including an Exchange subject to the procedures outlined in Treasury Regulation § 1.1031(k)-1 and/or Internal Revenue Service Revenue Procedure 2000-37.

(b) Anything herein to the contrary notwithstanding, Sellers shall have the right to assign all or a portion of the Assets to or between Brad Cross, Stella Swanson, or any of their respective Affiliates in order to effect the Exchange (any such Person, an “Exchange Assignee”), without prior approval of Purchaser;provided that Sellers and such Persons execute and deliver to Purchaser an Assignment, Ratification and Joinder Agreement in the form attached hereto asExhibit H. Notwithstanding anything to the contrary in this Agreement or any Assignment, Ratification and Joinder Agreement, the Exchange Assignees shall not have any liability to indemnify any member of the Purchaser Group pursuant toArticle 11 of this Agreement as a result of taking assignment of the Assets or executing an Assignment, Ratification and Joinder Agreement, and all such indemnity obligations shall be retained by the applicable original Seller party to this Agreement.

(c) Each of the Parties shall have the right at any time prior to Closing to assign all or a part of its rights under this Agreement to a qualified intermediary (as that term is defined in Treasury Regulation § 1.1031(k)-1(g)(4)(iii)) or an exchange accommodation titleholder (as that term is defined in Internal Revenue Service Revenue Procedure 2000-37) to effect an Exchange.

87

(d) Each Party acknowledges and agrees that neither an assignment of a Party’s rights under this Agreement nor any other actions taken by a Party or any other Person in connection with the Exchange shall release any Party from, or modify, any of its liabilities and obligations (including indemnity obligations to each other) under this Agreement, and no Party makes any representations as to any particular Tax treatment that may be afforded to any other Party by reason of such assignment or any other actions taken in connection with the Exchange.

(e) Any Party electing to treat the acquisition or sale of the Assets as an Exchange shall be obligated to pay all additional costs incurred hereunder as a result of the Exchange, and in consideration for the cooperation of the other applicable Party, the Party electing Exchange treatment shall agree to pay all costs associated with the Exchange and to indemnify and hold such other Party, its Affiliates, and their respective former, current and future partners, members, shareholders, owners, officers, directors, managers, employees, agents and representatives harmless from and against any and all liabilities and Taxes arising out of, based upon, attributable to or resulting from the Exchange or transactions or actions taken in connection with the Exchange that would not have been incurred by such other Party but for the electing Party’s Exchange election.

(f) Notwithstanding anything to the contrary in thisSection 9.3, none of the Parties shall be required to take any action under this Section if in such Party’s reasonable judgment such action would subject such Party to any material unreimbursed cost or expense.

9.4Equity Escrow Tax Treatment. In the event that Closing occurs, for federal and state income tax purposes, Purchaser Parent shall be treated as the owner of the Escrow Equity Consideration and thus shall take into account in filing its income tax returns all items of income, gain, loss and deduction with respect to the Escrow Equity Consideration. From and after the date any Escrow Equity Consideration is disbursed from the BSM Escrow Account, Purchaser and BSM shall be treated for tax purposes as the owners of the Escrow Equity Consideration disbursed to them, and thus each of Purchaser and BSM shall take into account in filing its Tax Returns its share of the items of income, gain, loss and deduction with respect to the Escrow Equity Consideration in accordance with Proposed Treasury Regulation Section 1.468B-8(e). Any amount distributed from the Escrow Equity Consideration to BSM shall be treated as a payment pursuant to Purchaser’s obligation to BSM arising from BSM’s sale of property to which the installment sale provisions of Section 453 of the Code, and the unstated interest provisions of Section 483 or 1274 of the Code, apply. For this purpose, Purchaser and BSM shall cooperate to provide to the Escrow Agent, at the time of any disbursement, a schedule indicating the allocation of such disbursement from the Escrow Equity Consideration between (a) principal and (b) imputed interest to be reported on IRS Form 1099-INT or 1099-OID. Neither Purchaser nor BSM shall take any position for federal or state income tax purposes that is inconsistent with the provisions of thisSection 9.4.

9.5Conflict. In the event of a conflict between the provisions of thisArticle 9 and any other provision of this Agreement, exceptSection 12.3(a), thisArticle 9 shall control.

11.4Indemnification Actions. All claims for indemnification underSection 11.3 shall be asserted and resolved as follows:

(a) For purposes of thisArticle 11, the term “Indemnifying Person” when used in connection with particular Damages means the Person having an obligation to indemnify another Person or Persons with respect to such Damages pursuant to thisArticle 11, and the term “Indemnified Person” when used in connection with particular Damages means a Person having the right to be indemnified with respect to such Damages pursuant to thisArticle 11 (including, for the avoidance of doubt, those Persons identified inSection 11.4(g)).

96

(b) To make a claim for indemnification underSection 11.3, an Indemnified Person shall notify the Indemnifying Person of its claim, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim against the Indemnified Person by a Person that is not an Affiliate of such Indemnified Person (a “Third-Party Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third-Party Claim and shall enclose a complete copy of all papers (if any) served with respect to the Third-Party Claim;provided that the failure of any Indemnified Person to give notice of a Third-Party Claim as provided in thisSection 11.4 shall not relieve the Indemnifying Person of its obligations underSection 11.3, except to the extent such failure results in insufficient time being available to permit the Indemnifying Person to effectively defend against the Third-Party Claim or otherwise prejudices the Indemnifying Person’s ability to defend against the Third-Party Claim. In the event that the claim for indemnification is based upon an inaccuracy or a breach of a representation, warranty, covenant, or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement that was inaccurate or breached and the reasonably specific details of, and specific basis for, such asserted inaccuracy or breach.

(c) In the case of a claim for indemnification based upon a Third-Party Claim, unless the situation requires a shorter period of time to respond to a Third-Party Claim, the Indemnifying Person shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies its obligation to defend the Indemnified Person against such Third-Party Claim under thisArticle 11. If the Indemnifying Person does not notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Person admits or denies its obligation to defend the Indemnified Person, it shall be deemed to have denied its obligation to provide such indemnification hereunder. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Person and that is not prejudicial to the Indemnifying Person.

(d) If the Indemnifying Person admits its indemnity obligations under thisArticle 11 with respect to any Third-Party Claim, then such Indemnifying Person shall have (i) the right and obligation to diligently prosecute and control the defense, at its sole cost and expense, of the Third-Party Claim and (ii) have full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement includes the payment of any amount by, the performance of any obligation by, or the limitation of any right or benefit of, the Indemnified Person, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be

97

unreasonably withheld or delayed. If requested by the Indemnifying Person, the Indemnified Person agrees at the cost and expense of the Indemnifying Person to cooperate in contesting any Third-Party Claim which the Indemnifying Person elects to contest;provided,however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person;provided, further, that if the Indemnified Person does not bring any applicable counterclaims or cross-complaints, the Indemnified Person shall assign such counterclaims or cross-complaints to the Indemnifying Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third-Party Claim controlled by the Indemnifying Party pursuant to thisSection 11.4(d),provided that the Indemnified Person may file initial pleadings as described in the last sentence ofSection 11.4(c) above if required by court or procedural rules to do so within the thirty (30) day period inSection 11.4(c) above. An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third-Party Claim or consent to the entry of any judgment with respect thereto that (A) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third-Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Third-Party Claim) or (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

(e) If the Indemnifying Person does not admit its obligation or admits its obligation but fails to diligently defend or settle the Third-Party Claim, then the Indemnified Person shall have the right, but not the obligation, to defend and control the defense against the Third-Party Claim (at the sole cost and expense of the Indemnifying Person, if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of the Indemnifying Person to admit its obligation to indemnify the Indemnified Person and assume the defense of the Third-Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Person has not yet admitted its obligation to indemnify the Indemnified Person, the Indemnified Person shall send written notice to the Indemnifying Person of any proposed settlement and the Indemnifying Person shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its obligation for indemnification with respect to such Third-Party Claim and (ii) if its obligation is so admitted, assume the defense of the Third-Party Claim, including the power to reject the proposed settlement. If the Indemnified Person settles any Third-Party Claim over the objection of the Indemnifying Person after the Indemnifying Person has timely admitted its obligation for indemnification in writing and assumed the defense of the Third-Party Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to the Third-Party Claim.

(b) In the event of a Casualty Loss, at the Purchaser’s election: (i) the Seller that owns an interest in any Assets affected by any Casualty Loss may cause such Assets to be fully repaired or restored (and any dispute regarding whether fully repaired or restored shall be resolved pursuant to the dispute resolution provisions hereof), at the applicable Seller’s sole cost, as promptly as reasonably practicable (but in any event prior to the Closing Date), and such Seller shall retain all rights to insurance and other claims against third Persons with respect to the Casualty Loss or taking except to the extent the Parties otherwise agree in writing); or (ii) the affected Assets shall be deleted from this Agreement and all exhibits and schedules hereto and shall constitute Excluded Assets, and the Unadjusted Purchase Price of such Seller shall be decreased by the Allocated Value thereof; or

11.6Limitation on Actions.

(a) The Purchaser Fundamental Representations shall survive indefinitely; the representations and warranties of Purchaser inArticle 5 and in the certificate delivered at Closing pursuant toSection 8.3(g) (other than the Purchaser Fundamental Representations) shall survive for a period of one (1) year following the Closing. The covenants of the Purchaser Parties to be performed prior to Closing shall survive until the Closing, and all other covenants of the Purchaser Parties in this Agreement to be performed at or after Closing shall survive Closing as reasonably necessary to perform the same, subject to the limitations set forth in thisSection 11.6. The representations and warranties of Sellers in set forth inArticle 4 and in the certificate delivered at Closing pursuant toSection 8.2(g) (other than the Seller Fundamental Representations and the representations and warranties inSections 4.3 and4.10) shall survive the Closing for a period of one (1) year.

The covenants of Sellers to be performed prior to Closing shall survive until the Closing, and all other covenants of the Sellers in this Agreement to be performed at or after Closing shall survive Closing as reasonably necessary to perform the same, subject to the other limitations set forth in thisSection 11.6. The remainder of this Agreement shall survive the Closing without time limit except as may otherwise be expressly provided herein. Representations, warranties, covenants, and agreements (and any and all rights to indemnification hereunder for the same) shall be of no further force and effect after the date of their expiration,provided that there shall be no termination of any bona fide claim asserted pursuant to this Agreement with respect to such a representation, warranty, covenant, or agreement prior to its expiration date. The representations, warranties and affirmations given in any certificate delivered pursuant to this Agreement by any Seller or any Purchaser Party, as applicable, shall survive for the period of survival of the respective representations, warranties and covenants which they cover, as described above in thisSection 11.6(a).

(b) The indemnities inSections 11.3(a)(ii) and(iii) andSections 11.3(b)(ii) and(iii) shall terminate as of the termination date of each respective representation, warranty, covenant, or agreement that is subject to indemnification, except in each case as to (i) matters for which a specific written claim for indemnity has been delivered to the Indemnifying Person on or before

100

such termination date, (ii) breaches of a Seller’s covenants inSections 6.3(b),(c),(f),(h) and(i) and11.3(h), which shall expire on the one year anniversary of the Closing Date and (iii) breaches of Purchaser’s covenants inSection 11.3(h), which shall expire on the one year anniversary of the Closing Date. The indemnity inSection 11.3(b)(i) shall survive the Closing without time limit. The indemnity inSection 11.3(a)(i) shall survive the Closing without time limit.

(c) No Seller shall have any liability for any indemnification underSection 11.3(b)(iii) for an individual matter until and unless the amount of the liability for Damages with respect to which such Seller agrees in writing (or it is otherwise finally determined) that such Seller has an obligation to indemnify the Indemnified Person pursuant to the terms ofSection 11.3(b)(iii) exceeds FIFTY THOUSAND AND NO/100 DOLLARS ($50,000.00) (the “Individual Claim Threshold”). Without limiting the foregoing, to the extent Damages for a particular matter do exceed the Individual Claim Threshold, no Seller shall have liability for any indemnification underSection 11.3(b)(iii) until and unless the aggregate amount of the liability of such Seller for Damages pursuant toSection 11.3(b)(iii) exceeds an amount equal to one percent (1%) of the aggregate Unadjusted Purchase Price of such Seller, and then, only to the extent that such Damages exceed such amount. No Seller shall be required to indemnify any Indemnified Person or Indemnified Persons for aggregate Damages pursuant toSection 11.3(b)(iii) in excess of 20% of the aggregate Unadjusted Purchase Price of such Seller. Notwithstanding the foregoing, the provisions of thisSection 11.6(c) shall not apply to or limit liability for Fraud or breaches of the Seller Fundamental Representations.

(e) The amount of any Damages for which Purchaser or Purchaser Group is entitled to indemnity under thisArticle 11 shall be reduced by the amount of insurance proceeds realized by such Indemnified Person or its Affiliates with respect to such Damages (net of any collection costs, and excluding the proceeds of any insurance policy issued or underwritten by such Indemnified Person or its Affiliates);provided,however, that no Party shall be required to seek recovery under any policy of insurance as a condition to indemnification hereunder.

(f) As used in this Agreement, the term “Damages” means the amount of any actual liability, damage, loss, cost, cost of collection, settlement and enforcement (but only to the extent the Indemnified Party is in compliance withSection 11.4 with respect to the applicable claim), expense, claim, award, or judgment incurred or suffered by any Indemnified Person arising out of or resulting

101

from the indemnified matter, whether attributable to personal injury or death, property damage, contract claims, torts, or otherwise, including reasonable fees and expenses of attorneys, consultants, accountants, or other agents and experts reasonably incident to matters indemnified against, and the reasonable costs of investigation and/or monitoring of such matters, and the costs of enforcement of the indemnity;provided,however, that “Damages” shall not include any adjustment for Taxes that may be assessed on payments under thisArticle 11 or for Tax benefits received by the Indemnified Person as a consequence of any Damages. Notwithstanding the foregoing, no Person shall be entitled to indemnification under thisArticle 11 for, and Damages shall not include, (i) loss of profits that are consequential, indirect, special, or other consequential damages suffered by the Party claiming indemnification, nor any punitive damages (other than loss of profits, consequential, indirect, special or punitive damages suffered by third Persons for which responsibility is allocated among the Parties); and (ii) any diminution of value or any increase in liability, loss, cost, expense, claim, award or judgment to the extent such increase is caused by the actions or omissions of any Indemnified Person after the Closing Date other than (A) loss of profits, consequential, indirect, special or punitive damages suffered by any Third Party for which responsibility is allocated among the Parties under the terms hereof or (B) Seller Equity Value Damages.

(g) BSM may, at its option, satisfy any indemnification obligation of BSM under this Agreement by forfeiting or otherwise delivering to Purchaser Parent shares of Common Stock with an aggregate value (calculated based on the Per Share Price) equal to value of such indemnification obligation.

(h) Any amounts payable by BSM underSection 11.3(b) shall, subject toSection 11.7(g), be payable (i) first, from the BSM Escrow Property held in the BSM Escrow Account (except for any BSM Escrow Property held in the BSM Escrow Account with respect to or constituting a Disputed Claim Amount) and (ii) second, only after all BSM Escrow Property has been disbursed from the BSM Escrow Account, by BSM.

(i) The Purchaser acknowledges that if it asserts an indemnity claim against a Seller for a breach of its obligations underSections 6.1(k),(l) or(n), and the subject matter of such breach also constitutes a breach of a Seller’s representation and warranty under this Agreement, the Purchaser’s remedies for such breach shall be limited to any indemnification claim (if any) for a breach of such representation and warranty.

(j) The Purchaser Parent acknowledges and agrees that BSM shall have the right to assert a direct claim for actual damages against Purchaser Parent for reductions in the value of the Equity Consideration that arise out of, relate to or result from breaches of Purchaser Parent’s representations and warranties under

102

Article V (“Seller Equity Value Damages”), and that BSM shall not have to assert such claim as a derivative claim on behalf of all the stockholders of Purchaser Parent.

(a) At Closing, Purchaser Parent shall deliver to the Escrow Agent 2,333,333 shares of Common Stock (the “Escrow Equity Consideration” as reduced pursuant to thisSection 11.7 and, together with any cash and non-cash dividends, securities and other property at any time received in exchange or respect of or otherwise in substitution of the Escrow Equity Consideration, the “BSM Escrow Property”) into the BSM Escrow Account to be governed by the BSM Indemnity Escrow Agreement. The BSM Escrow Property will be available to satisfy any payment obligations of BSM underSection 11.3(b).

(b) If, prior to the date on that is one (1) year following the Closing Date Purchaser delivers a Claim Notice to BSM, Purchaser may also deliver a written certification (a “Claim Certificate”) to the Escrow Agent (with a copy concurrently delivered to BSM) requesting a disbursement from the BSM Escrow Account in connection with such Claim Notice. Such a Claim Certificate will (i) include a copy of the applicable Claim Notice and (ii) specify the amount of (or if not finally determined, Purchaser’s good faith estimate of) the Damages owed by BSM underSection 11.3(b) (such amount, the “Claimed Amount”).

(c) If the Escrow Agent has not received a joint written instruction letter duly executed by each of BSM and the Purchaser in the form required by the BSM Indemnity Escrow Agreement (an “Indemnity Joint Written Instruction Letter”) instructing the Escrow Agent to disburse any portion of the BSM Escrow Property with respect to any portion of any Claimed Amount with respect to any Claim Notice within the earlier to occur of the date thirty (30) days after receipt by Escrow Agent of the Claim Certificate or the End Date, then BSM shall be deemed to dispute its obligation underSection 11.3(b) with respect to the portion of such Claimed Amount that BSM and Purchaser have not instructed the Escrow Agent to release (“Disputed Claim Amount”) and the Escrow Agent will retain in the BSM Escrow Account an amount of the BSM Escrow Property equal to such Disputed Claim Amount. Such Disputed Claim Amount will be disbursed by the Escrow Agent from the BSM Escrow Account only (a) upon the delivery to the Escrow Agent of an Indemnity Joint Written Instruction Letter or (b) pursuant to a final non-appealable judgment or decree of a court of competent jurisdiction instructing the Escrow Agent to disburse such Disputed Claim Amount (a “Final Determination”).

(d) On the date that is one (1) year following the Closing Date (the “End Date”), the Escrow Agent shall disburse to BSM from the BSM Escrow Account all BSM Escrow Property, save and except an amount equal to the

103

The Escrow Agent shall continue to hold the aggregate amount of all Disputed Claim Amounts (without duplication) until otherwise instructed to disburse any portion of such amount pursuant to any Indemnity Joint Written Instruction Letters or Final Determinations, as applicable.

(e) The Escrow Equity Consideration and any other BSM Escrow Property shall be valued in the manner provided in the BSM Indemnity Escrow Agreement for purposes of determining the number of shares of Escrow Equity Consideration or other BSM Escrow Property to be disbursed from the BSM Escrow Account pursuant to the provisions of thisSection 11.7.

(f) At any time, Purchaser and BSM may execute join written instructions instructing the Escrow Agent to disburse all or any portion of the BSM Escrow Property pursuant to an Indemnity Joint Written Instruction Letter.

(g) The Parties agree and acknowledge that subject toSection 11.6, the BSM Escrow Property shall not be deemed a limitation to Purchaser remedies against BSM pursuant to this Agreement. To the extent that Purchaser is determined to be owed by BSM amounts in excess of the BSM Escrow Property, then, subject toSection 11.6, BSM shall be liable to, and Purchaser may pursue, payment for such amounts.
