If the Owner Representative and the Buyer do not agree on changes to such amounts, then the Closing Payment Amount to be paid at Closing shall be determined based on the amounts set forth in the Estimated Closing Statement initially delivered by the Companies. In either such case, appropriate adjustments to the Merger Consideration shall be made after the Closing pursuant to Sections 2.9(c) and 2.9(d).

(i) As soon as reasonably practicable following the Closing Date, but in no event later than 60 days after the Closing Date, the Buyer Parties shall prepare in good faith and deliver to the Owner Representative a statement (the “Closing Statement”), setting forth (A) Expenses, the Debt Payoff Amount and a reasonably detailed proposed final calculation of (1) the Net Working Capital as of the Effective Time (“Effective Time Net Working Capital”) calculated in the same manner as the calculation of the Balance Sheet Date Net Working Capital set forth on Exhibit 2.9(a), (2) the Net Income Amount calculated in the same manner as the calculation on Exhibit 2.9(b) and (3) the Reimbursable Amount,

together with reasonably detailed supporting information, (B) based on such Effective Time Net Working Capital, the Working Capital Adjustment Amount and (C) based on such amounts, the Merger Consideration Surplus or the Merger Consideration Deficit.

(ii) From and after the delivery of the Closing Statement, the Buyer Parties shall provide the Owner Representative and its Representatives reasonable access to the records and employees of the Buyer Parties and their Affiliates and shall cause the employees of the Buyer Parties and their Affiliates to cooperate in all reasonable respects with the Owner Representative in connection with its review of such work papers and other documents and information relating to the calculation of Expenses, the Debt Payoff Amount, the Reimbursable Amount, the Effective Time Net Working Capital and the Net Income Amount, as the Owner Representative shall reasonably request and that are available to the Buyer Parties and their Affiliates.

(iii) Within 30 days after the Owner Representative’s receipt of the Closing Statement, the Owner Representative shall notify the Buyer if the Owner Representative disagrees with the Closing Statement, which notice shall set forth in reasonable detail the particulars of such disagreement (the “Objection Notice”). If the Owner Representative provides a notice of agreement or does not deliver to the Buyer an Objection Notice within such 30-day period, then the Owner Representative shall be deemed to have accepted the calculations and the amounts set forth in the Closing Statement delivered by the Buyer, which shall then be final, binding and conclusive for all purposes hereunder. If any such Objection Notice is timely delivered, then the Owner Representative and the Buyer shall each endeavor in good faith for a period of 30 days thereafter to resolve any disagreements with respect to the calculations in the Closing Statement.

(iv) If, at the end of the 30-day resolution period, the Owner Representative and the Buyer are unable to resolve any disagreement between them with respect to the preparation of the Closing Statement, then each such Party shall deliver simultaneously to PricewaterhouseCoopers (or if such firm is unwilling or unable to serve, another nationally recognized accounting firm mutually agreed on by such Parties, the accounting firm ultimately chosen, the “Accountants”) the Objection Notice, the Closing Statement and any engagement, indemnity and other agreements as the Accountants may require as a condition to such engagement (each a “Submission”) within 5 days of retaining the Accountants (the “Closing Statement Submission Deadline”). Such Parties shall instruct the Accountants to deliver to the Parties a written determination (such determination to include a worksheet setting forth all material calculations used in arriving at such determination and to be based solely on information provided to the Accountants by the Parties, or their respective Affiliates) of, and the Accountants’ engagement shall be limited to the resolution of, disputed amounts set forth in the Closing Statement that have been identified by the Owner Representative in the Objection Notice, which resolution shall be in

accordance with this Agreement, and no other matter relating to the Closing Statement shall be subject to determination by the Accountants except to the extent affected by resolution of the disputed amounts. In resolving any disputed item, the Accountants shall not assign a value to any item greater than the greatest value for such item claimed by the Buyer or the Owner Representative or less than the smallest value for such item claimed by the Buyer or the Owner Representative. Such Parties shall cooperate diligently with any reasonable request of the Accountants in an effort to resolve any disputed matter as soon as reasonably possible after the Accountants are engaged. If possible, the decision of the Accountants shall be made within 20 days after the Closing Statement Submission Deadline. The fees and expenses of the Accountants shall be allocated by the Accountants between the Buyer Parties, on the one hand, and the Zephyr Owners, on the other hand, and in accordance with their Zephyr Owner Percentage (which the Owner Representative must first pay out of the Owner Representative Reserve, to the extent available), so that the aggregate amount of such fees and expenses paid by the Zephyr Owners bears the same proportion to the total fees and expenses as the aggregate dollar amount of items unsuccessfully disputed by the Owner Representative, if any (as determined by the Accountants), bears to the total dollar amount of items in dispute, and the Buyer Parties shall pay the remainder of such fees and expenses, if any. The determination of the Accountants shall be final, binding and conclusive for all purposes hereunder, absent manifest error or fraud.

(d) True-Up Payment. If the Final Adjustment Amount is less than the Estimated Adjustment Amount (the amount of such shortfall, if any, the “Merger Consideration Deficit”), the Owner Representative and Buyer Parties shall, within 5 Business Days after the final determination of the Closing Statement, promptly deliver joint instructions to the Escrow Agent, instructing the Escrow Agent to (i) pay to Buyer from the Escrow Account, in cash by wire transfer of immediately available funds to an account designated by Buyer, an amount equal to the Merger Consideration Deficit and (ii) pay to an account or accounts designated by the Owner Representative in cash by wire transfer of immediately available funds, an amount equal to $9,250,000.00 less the Merger Consideration Deficit (if such difference is a positive number).

(e) No Duplicative Effect. The provisions of this Section 2.9 shall apply in such a manner so as not to give the components and calculations duplicative effect to any item of adjustment and, the Parties covenant and agree that no amount shall be (or is intended to be) included, in whole or in part (either as an increase or reduction) more than once in the calculations of (including any component of) Net Working Capital or any other calculated amount pursuant to this Agreement if the effect of such additional inclusion (either as an increase or reduction) would be to cause such amount to be overstated or understated for purposes of such calculation.

The provisions of this Section 5.7 shall survive the consummation of the Merger and expressly are intended to benefit, and are enforceable by, each Company Indemnified Party (and any other individuals entitled to indemnification or similar rights under Section 5.7(a)).

The Buyer Parties shall have 10 Business Days to review each Schedule Update and the Closing Date shall be postponed as necessary for Buyer to do so (the “Review Period”).

ARTICLE VI

TAX MATTERS

6.1 Responsibility for Filing Tax Returns, Payment of Taxes.

(a) Pre-Closing Tax Returns. The Owner Representative shall prepare all Tax Returns required to be filed by or with respect to each Company for a Pre-Closing Tax Period (“Pre-Closing Tax Returns”). For the avoidance of doubt, the Owner Representative shall cause to be prepared and timely filed the federal income Tax Returns for the Companies on IRS Form 1065 and all corresponding state income Tax Returns for the period that ends on the Closing Date. The Pre-Closing Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Not later than twenty (20) days prior to the due date for filing any such Tax Return, the Owner Representative shall deliver a copy of such Tax Return, together with all supporting documentation and workpapers, to Buyer for its review and reasonable comment. The Buyer will cause such Tax Return (as revised to incorporate Buyer’s reasonable comments) to be timely filed and will provide a copy to the Owner Representative. Not later than five (5) days prior to the due date for payment of Taxes with respect to any Pre-Closing Tax Return, the Zephyr Owners shall pay to the Buyer the amount of any Zephyr Owner Taxes with respect to such Tax Return.

(b) Straddle Period Tax Returns. Buyer shall prepare or cause to be prepared all Tax Returns of the Companies for all Straddle Periods (“Straddle Tax Returns”). Such Tax Returns shall be prepared on a basis consistent with past practice except to the extent otherwise required by applicable Law. Buyer shall file, or cause to be filed, all Straddle Tax Returns. Buyer shall provide a copy of each Straddle Tax Return, together with all supporting documentation and workpapers, to the Owner Representative at least twenty (20) days before the due date for such Tax Return. Prior to the filing of any Straddle Tax Return, Buyer shall make any revisions or adjustments reasonably requested by the Zephyr Owners. Not later than five (5) days prior to the due date for payment of Taxes with respect to any Straddle Tax Return, the Zephyr Owners shall pay to the Buyer the amount of any Zephyr Owner Taxes with respect to such Tax Return for the amounts owed by the Zephyr Owners as calculated in the following sentence. Liability for Taxes attributable to a Straddle Period shall be apportioned between Buyer and Zephyr Owners as follows: (i) property and similar ad valorem Taxes shall be apportioned to the Zephyr Owners for the period up to and including the Closing Date and to the Buyer for the period after the Closing Date on a ratable daily basis; and (ii) all other Taxes shall be apportioned between Buyer and Zephyr Owners based on an interim closing of the books of each of the Companies as of the Closing Date. For this purpose, any margin or franchise Tax paid or payable with respect to the Companies shall be allocated to the

taxable period during which the income, receipts, operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another taxable period is obtained by the payment of such Tax.

6.2 Responsibility for Tax Audits and Contests. The Zephyr Owners shall control any audit or contest with respect to any Taxes for a Pre-Closing Tax Period; provided, however, that the Party with the greater potential Tax liability shall control any audit or contest with respect to a Straddle Period; provided further, that the Party so in control of an audit or contest with respect to a Straddle Period shall allow the other Party to participate at such other Party’s cost and expense. The Party in control of an audit or controversy shall keep the other Party informed of the status of the audit or controversy (including providing copies of correspondence and pleadings). Neither Buyer nor the Zephyr Owners shall settle any audit or contest in a way that would adversely affect the other Party without the other Party’s written consent, which the other Party shall not unreasonably withhold.

6.3 Cooperation on Tax Matters. The Buyer, the Zephyr Owners and the Owner Representative shall cooperate fully as and to the extent reasonably requested by another Party, in connection with the filing of Tax Returns and any audit or contest with respect to Taxes imposed on or with respect to the assets, operations or activities of the Companies. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or audit or contest. The Owner Representative further agrees, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on the Buyer or the Companies (including, but not limited to, with respect to the transactions contemplated hereby).

6.4 Amended Tax Returns. Unless required by applicable Law or as set forth below, Buyer agrees not to amend any of the Companies’ previously filed Tax Returns without Zephyr Owners’ prior consent if such amended Tax Return or settlement would increase (other than a de minimis amount) the amount of Zephyr Owner Taxes. Notwithstanding the above, Buyer may file or cause to be filed an amended Tax Return even if not required by applicable Law without the consent of the Zephyr Owners, provided that any additional Taxes resulting therefrom will not be deemed to constitute Zephyr Owner Taxes.

6.5 Tax Refunds. The Zephyr Owners shall be entitled to any refund of Taxes paid with respect to Taxes for a Pre-Closing Tax Period. Buyer shall be entitled to all other refunds except that refunds for a Straddle Period shall be apportioned between the Buyer and the Zephyr Owners in accordance with the principles set forth in Section 6.1(b). If a Party receives a refund to which the other Party is entitled, the Party receiving the refund shall pay it to the Party entitled to the refund within twenty (20) Business Days after receipt, net of any costs or expenses incurred by such party or its Affiliates in procuring such refund.

6.6 Transfer Taxes. All state or local transfer, sales, use, stamp, registration or other similar Taxes resulting from the transactions contemplated by this Agreement, together with any interest, penalties or additions thereto, shall be borne equally by Buyer and the Zephyr Owners.

6.7 Merger Consideration Allocation. At least five (5) days prior to the Closing, the Owner Representative shall deliver a proposed Allocation (as defined below) to the Buyer. The Owner Representative and Buyer shall thereafter use their best efforts to agree on the Allocation. The Merger Consideration (together with the liabilities of the Companies assumed by the Buyer) shall be allocated among the assets of the Companies subject to any applicable Code sections and Treasury regulations (and any similar provision of state, local or foreign Law, as appropriate) (the “Allocation”). The Zephyr Owners and Buyer shall report the transactions contemplated hereby on all Tax Returns, including, but not limited to Form 8594, as applicable, in a manner consistent with the Allocation. If the Merger Consideration is subsequently adjusted for any reason such that an adjustment to the Allocation is needed in order for such Allocation to comply with this Section 6.7, the Owner Representative shall prepare such adjustment to the Allocation which adjustment shall be submitted to Buyer, and the Owner Representative and Buyer shall use their best efforts to agree on the final adjustment within thirty (30) days after the determination of the adjusted Merger Consideration. Buyer and its Affiliates shall timely and properly prepare, execute, file, and deliver all such documents, forms, and other information as the Owner Representative may reasonably request in preparing any required adjustment to the Allocation. If, contrary to the intent of the parties hereto as expressed in this Section 6.7, any Taxing authority makes or proposes an allocation different from the Allocation determined under this Section 6.7, the Owner Representative and Buyer shall cooperate with each other in good faith to contest such Taxing authority’s allocation (or proposed allocation), provided, however, that, after consultation with the party (or parties) adversely affected by such allocation (or proposed allocation), the other party (or parties) hereto may file such protective claims or Tax Returns as may be reasonably required to protect its (or their) interests.

6.8 Disputes over Tax Provisions. The Accountants shall resolve any dispute between Buyer and the Zephyr Owners over the calculation of Taxes and under this Article VI substantially in the manner described in Section 2.9(c)(iv).

(c) Notwithstanding the foregoing, any representation, warranty, covenant or agreement in respect of which indemnity may be sought under this Agreement will survive the time at which it would otherwise terminate pursuant to the preceding provisions if written notice of the inaccuracy or breach thereof giving rise to such right of indemnity has been given to the Party against whom such indemnification may be sought prior to such time; provided that such right of indemnity shall continue to survive and shall remain a basis for indemnification hereunder only until the related claim for indemnification is resolved or disposed of in accordance with the terms of this Article VIII (any such claim, a “Continuing Claim”).

8.2 Indemnification.

(a) From and after the Closing, subject to the limitations set forth in this Article VIII, the Zephyr Owners will jointly and severally (except for Individual Claims as provided in Section 8.2(a)(ii), which shall be several and not joint subject to Section 8.2(c)) indemnify, defend and hold harmless the Buyer Parties and their officers, members, directors, partners, managers, employees and Affiliates (the “Buyer Indemnified Parties”) against any and all claims, demands, causes of action, Liabilities, damages, judgments, losses, costs and expenses (including reasonable attorneys’ and consultants’ fees and expenses) (“Losses”) incurred or suffered as a result of, relating to or arising out of:

(i) any inaccuracy or breach of any representation or warranty made by the Companies in this Agreement (other than any representation or warranty made by the Companies in Section 3.3 or Section 3.9 of this Agreement or any closing certificate delivered pursuant to Section 7.1(a) as it relates to such representations and warranties);

(ii) the inaccuracy or breach of a representation or warranty made by a Zephyr Owner in a Letter of Transmittal (only with respect to representations and warranties regarding title to the Units and Membership Interests and authority of such Zephyr Owner (an “Individual Claim”)) and the inaccuracy or breach of any representation or warranty made by the Companies in Section 3.3 of this Agreement or any closing certificate delivered pursuant to Section 7.1(a) solely to the extent it relates to such representations and warranties;

(iii) the breach or non-performance of any covenant or agreement made or to be performed by the Companies pursuant to this Agreement or any closing certificate delivered pursuant to Section 7.1(a);

(iv) the Merger Consideration Deficit, if any;

(v) any Third-Party Debt, Expenses, Change of Control Amounts and Severance Obligations that do not result in a reduction in the Merger Consideration pursuant to Section 2.8 or Section 2.9; and

(vi) any and all Zephyr Owner Taxes.

(b) From and after the Closing, the Buyer Parties will jointly and severally indemnify, defend and hold harmless the Zephyr Owners and their officers, members, directors, partners, managers, employees and Affiliates (the “Owner Indemnified Parties”) against any and all Losses incurred or suffered as a result of, relating to or arising out of:

(i) the inaccuracy or breach of any representation or warranty made by the Buyer Parties in this Agreement or any closing certificate delivered pursuant to Section 7.2(a), to the extent such a representation or warranty survives the Closing;

(ii) the breach or non-performance of any covenant or agreement made or to be performed by any Buyer Parties pursuant to this Agreement or any closing certificate delivered pursuant to Section 7.2(a); and

(c) The indemnification obligations of a Zephyr Owner with respect to an Individual Claim will be joint and several with the indemnification obligations of all other Zephyr Owners to the extent of any Losses incurred solely to the extent that there are funds remaining in the Escrow Account to cover such Losses. To the extent that there are insufficient funds remaining in the Escrow Account to cover such Losses, the indemnification obligations of each Zephyr Owner with respect to such Individual Claim shall be several and not joint solely to the extent of any Losses incurred in excess of the amount remaining in the Escrow Account.

8.3	Limitations on Liability.

(a) Notwithstanding anything herein to the contrary, the Zephyr Owners’ obligations pursuant to Section 8.2(a) are subject to the following additional limitations:

(i) the Buyer Indemnified Parties shall not be entitled to recover under Section 8.2(a)(i) for any individual item or series of related items arising out of the same or similar set of facts or circumstances where the Losses relating thereto for which the Zephyr Owners would otherwise be required to indemnify are less than $25,000 (each, a “De Minimis Loss Amount”) and no De Minimis Loss Amounts shall be included in the calculation of the Basket;

(ii) the Buyer Indemnified Parties shall not be entitled to recover under Section 8.2(a)(i), until the aggregate Losses which the Buyer Indemnified Parties

have incurred under Section 8.2(a)(i), exceeds $1,850,000.00 (the “Basket”), at which point the Buyer Indemnified Parties will be entitled to Losses in excess of the Basket up to the Ceiling;

(iii) the Buyer Indemnified Parties shall not be entitled to recover under Sections 8.2(a)(i), 8.2(a)(iii), 8.2(a)(iv), 8.2(a)(v) and 8.2(a)(vi) for Losses in excess of the amount in the Escrow Account (the “Ceiling”);

(iv) with respect to Non-Escrow Indemnity Claims, a Buyer Indemnified Party shall not be entitled to recover from any Zephyr Owner in excess of an amount equal to the applicable Zephyr Owner Percentage multiplied by the amount of Losses incurred with respect to such claims (the “Individual Indemnity Limit”); provided this Individual Indemnity Limit shall not prevent a Buyer Indemnified Party from recovering the full amount of any indemnification claim from the Escrow Account irrespective of the Zephyr Owner Percentage of any Zephyr Owner; and

(v) in no event shall a Buyer Indemnified Party be entitled to recover from a Zephyr Owner in excess of the Merger Consideration actually received by such Zephyr Owner (taking into account any distributions from the Escrow Account for Individual Claims with respect to such Zephyr Owner).

(b) Waiver of Consequential Damages. With respect to any and all Losses for which indemnification may be available hereunder, no Indemnifying Parties shall have any liability for any consequential, indirect, punitive, exemplary, and special damages with respect to any claim for which an Indemnifying Party may have liability pursuant to this Agreement; provided, however, that this waiver shall not apply to the extent such consequential, indirect, punitive, exemplary or special damages are (i) awarded in a Proceeding brought or asserted by a third party against an Indemnified Party, or (ii) actually paid by an Indemnified Party to a third party.

(c) ESCROW AMOUNT. EXCEPT WITH RESPECT TO NON-ESCROW INDEMNITY CLAIMS, THE AMOUNT IN THE ESCROW ACCOUNT SHALL BE THE SOLE RECOURSE FOR ANY PAYMENT REQUIRED TO BE MADE BY THE ZEPHYR OWNERS TO ANY BUYER INDEMNIFIED PARTY PURSUANT TO THIS AGREEMENT. EXCEPT WITH RESPECT TO NON-ESCROW INDEMNITY CLAIMS, THE AMOUNT IN THE ESCROW ACCOUNT SHALL BE THE MAXIMUM AMOUNT OF LOSSES RECOVERABLE BY ANY BUYER INDEMNIFIED PARTY PURSUANT TO THIS AGREEMENT. SUBJECT TO THE LIMITATIONS SET FORTH IN SECTIONS 8.3(a)(iv) and 8.3(a)(v), IF A CLAIM FOR INDEMNIFICATION IS BROUGHT BY A BUYER INDEMNIFIED PARTY WITH RESPECT TO A NON-ESCROW INDEMNITY CLAIM, THE BUYER INDEMNIFIED PARTY MAY FIRST RECOVER THE LOSSES INCURRED WITH RESPECT TO SUCH CLAIM FROM THE ESCROW ACCOUNT IN ACCORDANCE WITH THE ESCROW AGREEMENT TO THE EXTENT OF AMOUNTS AVAILABLE IN THE ESCROW ACCOUNT, AND THEREAFTER SHALL BE ENTITLED TO RECOVER ANY LOSSES WITH RESPECT TO A NON-ESCROW INDEMNITY CLAIM NOT RECOVERED FROM THE ESCROW ACCOUNT FROM THE APPLICABLE ZEPHYR OWNER.

(d) Exclusive Remedy and Release. Other than with respect to claims for fraud, the indemnification and remedies set forth in this Article VIII shall, from and after the Closing, constitute the sole and exclusive remedies of the Parties with respect to any breach of representation or warranty or non-performance, partial or total, of any covenant or agreement (except for the covenants contained in Section 2.9(d), Section 5.2(b), Section 5.5, Section 5.7, and Article VI) contained in this Agreement; provided that nothing in this Section 8.3 shall prevent either Party from seeking injunctive or equitable relief, including, but not limited to, specific performance.

(e) Disclaimer. EACH BUYER PARTY HEREBY ACKNOWLEDGES AND AGREES THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN ARTICLE III AND IN THE CERTIFICATE(S) TO BE DELIVERED PURSUANT TO SECTION 7.1(a), AND THE REPRESENTATIONS AND WARRANTIES OF THE ZEPHYR OWNERS IN THE LETTERS OF TRANSMITTAL, THERE ARE NO REPRESENTATIONS OR WARRANTIES WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO ANY MATTER RELATING TO THE COMPANIES, THE UNITS, THE MEMBERSHIP INTERESTS, THE PHYSICAL CONDITION OF ANY OF THE ASSETS OF THE COMPANIES, THE ENVIRONMENTAL CONDITION OR OTHER MATTERS RELATING TO THE PHYSICAL CONDITION OR USE OF ANY ASSETS OF THE COMPANIES, THE VALUE OF THE ASSETS OF THE COMPANIES (OR ANY PORTION THEREOF), THE MERCHANTABILITY OR FITNESS OF THE PERSONAL PROPERTY OR ANY OTHER PORTION OF THE ASSETS OF THE COMPANIES FOR ANY PARTICULAR PURPOSE AND ANY STATEMENTS OR INFORMATION CONTAINED IN THE ANY OTHER MATERIALS FURNISHED OR STATEMENTS MADE BY THE COMPANIES OR THEIR REPRESENTATIVES (INCLUDING, WITHOUT LIMITATION, ANY PROJECTIONS, ESTIMATES OR BUDGETS DELIVERED TO OR MADE AVAILABLE TO BUYER OF FUTURE REVENUES, FUTURE RESULTS OF OPERATIONS, FUTURE CASH FLOWS OR FUTURE FINANCIAL CONDITION OF THE COMPANIES, OR ANY OTHER INFORMATION MADE AVAILABLE TO THE BUYER PARTIES OR THEIR REPRESENTATIVES AT ANY TIME IN ANY AND ALL “DATA ROOMS,” MANAGEMENT PRESENTATIONS, CONFIDENTIAL INFORMATION MEMORANDA, BREAK-OUT SESSIONS, OR RESPONSES TO QUESTIONS SUBMITTED BY THE BUYER PARTIES OR THEIR REPRESENTATIVES). WITHOUT IN ANY WAY LIMITING THE FOREGOING, THE COMPANIES HEREBY DISCLAIM ANY WARRANTY, EXPRESS OR IMPLIED, AS TO TITLE AND AS TO MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE, WITH RESPECT TO ANY PORTION OF THE ASSETS OF THE COMPANIES, THE UNITS OR THE MEMBERSHIP INTERESTS, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN ARTICLE III AND IN THE CERTIFICATE(S) TO BE DELIVERED PURSUANT TO SECTION 7.1(a), AND THE REPRESENTATIONS AND WARRANTIES OF THE ZEPHYR OWNERS IN THE LETTERS OF TRANSMITTAL.

(f) THE COMPANIES HEREBY ACKNOWLEDGE AND AGREE THAT, EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN ARTICLE IV AND IN THE CERTIFICATE(S) TO BE DELIVERED PURSUANT TO SECTION 7.2(A), THERE ARE NO REPRESENTATIONS OR WARRANTIES WHATSOEVER, EXPRESS OR IMPLIED, WITH RESPECT TO ANY MATTER RELATING TO THE BUYER PARTIES MADE BY THE BUYER PARTIES OR THEIR REPRESENTATIVES.

(g) Buyer is not entitled to indemnification under this Article VIII in respect of the calculation of the Final Adjustment Amount, or matters reflected in the calculation thereof, except to the extent that a value used in the calculation of Final Adjustment Amount is inaccurate because of the failure of a representation or warranty made by Companies in this Agreement to be true and correct as of the Closing. If the Buyer Parties are entitled to indemnification due to the exception set forth in the previous sentence, the Buyer Parties’ claim shall be limited to the amount that exceeds the inaccurate value reflected in the calculation of the Final Adjustment Amount, and is subject to the limitations on indemnification hereunder, including without limitation the Basket and Ceiling; provided that if any difference between the Estimated Adjustment Amount and the Final Adjustment Amount is the direct result of such a failure, Buyer shall not be entitled to indemnification for such failure under this Article VIII.

8.4 Procedures. Claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a) If any Person who or which is entitled to seek indemnification under Section 8.2 (an “Indemnified Party”) receives notice of the assertion or commencement of any claim asserted against an Indemnified Party by a third party (“Third-Party Claim”) in respect of any matter that is subject to indemnification under Section 8.2, the Indemnified Party shall promptly (i) notify the Party(ies) obligated to indemnify (the “Indemnifying Party”) of the Third-Party Claim and (ii) transmit to the Indemnifying Party a written notice (“Claim Notice”) describing in reasonable detail the nature of the Third-Party Claim, a copy of all papers served with respect to such claim (if any), the Indemnified Party’s best estimate of the amount of Losses attributable to the Third-Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

(b) The Indemnifying Party shall have the right to defend the Indemnified Party against such Third-Party Claim at the Indemnifying Party’s sole cost and expense. If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third-Party Claim (such election to be without prejudice to the right of the Indemnifying Party to dispute whether such claim is an indemnifiable Loss under this Article VIII), then the Indemnifying Party shall have the right to defend such Third-Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying

Party in accordance with this Section 8.4(b). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided that the Indemnifying Party shall not enter into any settlement agreement without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned or delayed); provided further, that such consent shall not be required if (i) the settlement agreement contains a complete and unconditional general release by the third party asserting the claim to all Indemnified Parties affected by the claim, (ii) the settlement agreement does not contain any sanction or restriction upon the conduct of any business by, and does not contain an injunction or other equitable relief upon, the Indemnified Party or its Affiliates. Notwithstanding the foregoing, the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party if the Indemnified Party is advised by outside counsel reasonably satisfactory to the Indemnifying Party that a conflict of interest exists that requires the Indemnified Party to be represented by separate counsel under the applicable rules of professional responsibility or if the court in which such Third-Party Claim is pending determines that a conflict of interest exists such that the Indemnifying Party’s counsel is prohibited by such court or otherwise unable to represent the Indemnified Party with respect to such Third-Party Claim or if there is one or more defenses that could be asserted by the Indemnified Party that could not be asserted by the Indemnifying Party or the Indemnifying Party’s counsel (on the Indemnified Party’s behalf), and, in the event the Indemnified Party has the right to employ separate counsel for the reasons set forth in this sentence, the reasonable expenses and fees of such separate counsel shall be paid by the Indemnifying Party. If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third-Party Claim which the Indemnifying Party elects to contest, including the making of any related counterclaim against the Person asserting the Third-Party Claim or any cross complaint against any Person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third-Party Claim controlled by the Indemnifying Party pursuant to this Section 8.4(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c) Unless and until the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 8.4(b), the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third-Party Claim with counsel selected by the Indemnified Party (who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third-Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third-Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 8.4(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d) Any claim by an Indemnified Party on account of Losses that does not result from a Third-Party Claim (a “Direct Claim”) will be asserted by giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 days after the Indemnified Party becomes aware of such Direct Claim. Such notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include copies of all available material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of Losses that have been or may be sustained by the Indemnified Party. The Indemnifying Party will have a period of five (5) Business Days within which to respond in writing to such Direct Claim. If the Indemnifying Party does not so respond within such period, the Indemnifying Party will be deemed to have rejected such claim, in which event the Indemnified Party will be free to pursue such remedies as may be available to the Indemnified Party subject to the provisions of this Agreement.

(e) Any indemnification payment made pursuant to this Agreement shall be net of any insurance proceeds realized by and paid to the Indemnified Party in respect of such claim.

8.5 Characterization of Payments. For all applicable income Tax purposes, the parties agree to treat (and will cause each of their respective Affiliates to treat) any indemnification payment under this Article VIII as an adjustment to the Merger Consideration.

8.6 Losses. Notwithstanding anything to the contrary in this Agreement, for purposes of determining whether a breach has occurred and the amount of Losses suffered by any Buyer Indemnified Party, upon a breach of any representation or warranty of the Companies or a Zephyr Owner, each representation and warranty set forth in Article III (other than in any defined terms such as “Material Contract”), shall be read without regard to and without giving effect to any “material,” “materiality,” Material Adverse Effect or similar qualifications that may be contained in any such representation or warranty.

ARTICLE IX

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

(b) by the Buyer by written notice to the Companies, if there has been a breach by any Company of any representation, warranty or covenant contained in this Agreement (except where such breach would not reasonably be expected to have a Company Material Adverse Effect) that has prevented the satisfaction of any condition to the obligations of the Buyer Parties at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by the Companies within

20 days after written notice thereof from the Buyer Parties; provided, however, if such breach is capable of being cured but is not capable of being cured within such 20 day period, it shall be sufficient for the Companies to commence the cure within such 20 day period and use Reasonable Efforts to continue to cure;

(c) by the Companies by written notice to the Buyer Parties, if there has been a breach by any Buyer Party of any representation, warranty or covenant contained in this Agreement (except where such breach would not reasonably be expected to have a Buyer Material Adverse Effect) that has prevented the satisfaction of any condition to the obligations of the Companies at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by the Buyer Parties within 20 days after written notice thereof from the Companies; provided, however, if such breach is capable of being cured but is not capable of being cured within such 20 day period, it shall be sufficient for the Buyer Parties to commence the cure within such 20 day period and use Reasonable Efforts to continue to cure, except that this additional cure period shall not apply to a breach regarding the failure or inability of a Buyer Party to pay any portion Merger Consideration or a breach of the representation set forth in Section 4.6;

(d) by either the Buyer Parties or the Companies by written notice to the other, if any Governmental Authority having competent jurisdiction has issued a final, non-appealable Order, decree, ruling or injunction (other than a temporary restraining order) or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such other action shall have become final and non-appealable; provided, however, that no Party may terminate this Agreement pursuant to the terms of this Section 9.1(d) if such Party has not first complied with its obligations under Section 5.4;

(e) by either the Buyer Parties or the Companies by written notice to the other, if the transactions contemplated hereby have not been consummated by 90 days from the date of this Agreement (the “Termination Date”), provided, that neither the Buyer Parties nor the Companies will be entitled to terminate this Agreement pursuant to this Section 9.1(e) if such Person’s breach of this Agreement has prevented the consummation of the transactions contemplated by this Agreement; or

(f) by the Buyer Parties or the Companies by written notice to the other as provided in Section 7.4 with respect to a Casualty Loss.

9.2 Effect of Termination. If this Agreement is terminated under Section 9.1, all further obligations of the Parties under this Agreement will terminate without further liability or obligation of either Party to the other Parties hereunder; provided, however, that no Party will be released from liability hereunder if this Agreement is terminated and the transactions abandoned by reason of (a) failure of such Party to have performed its material obligations under this Agreement or (b) any material misrepresentation made by such Party of any matter set forth in this Agreement. Nothing in this Section 9.2 will relieve any Party to this Agreement of liability for breach of this Agreement occurring prior to any termination, or for breach of any provision of this Agreement that specifically survives termination hereunder. The Confidentiality Agreement shall not be affected by a termination of this Agreement.

No reference to or disclosure of any item or other matter in the Disclosure Schedule shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedule. No disclosure in the Disclosure Schedule relating to any possible breach or violation of any agreement or Law shall be construed as an admission or indication that any such breach or violation exists or has actually occurred.

The Parties further agree, to the extent permitted by Law, that a final and nonappealable judgment against a Party in any action or proceeding contemplated above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified or exemplified copy of which shall be conclusive evidence of the fact and amount of such judgment. Except to the extent that a different determination or finding is mandated due to the applicable Law being that of a different jurisdiction, the Parties agree that all judicial determinations or findings by a state or federal court in Houston, Texas with respect to any matter under this Agreement shall be binding.

10.12 Owner Representative.

(a) The Owner Representative, after appointment by the Zephyr Owners, shall serve as their attorney-in-fact and agent to the Zephyr Owners and their successors in their name, place and ▇▇▇▇▇ in connection with the authority granted to such Owner Representative pursuant to this Section 10.12.

(b) After appointment by the Zephyr Owners, the Owner Representative will act as the sole point of contact between the Buyer Parties and the Zephyr Owners, to take any and all actions required or permitted to be taken by the Owner Representative under or in connection with this Agreement and to do all things and execute any and all documents which may be necessary, convenient or appropriate to facilitate the consummation of the transactions contemplated by this Agreement, and for the following additional purposes: (A) to give and receive notices and communications to or from the Buyer Parties relating to this Agreement and the Ancillary Agreements and the other transactions contemplated by this Agreement and the Ancillary Agreements; (B) to execute and deliver the Paying Agent Agreement at the Closing, to give and receive notices and communications to or from the Paying Agent in matters relating to the Paying Agent Agreement, and to otherwise perform the Owner Representative’s obligations as set forth in the Paying Agent Agreement; (C) to act on such Zephyr Owner’s behalf with respect to the matters set forth in Section 2.9, in accordance with the terms and provisions of Section 2.9, including giving and receiving all notices and communications to be given or received with respect to the matters set forth in Section 2.9; (D) to authorize deliveries to the Buyer Parties of cash from the Escrow Account in satisfaction of claims for indemnification pursuant to Article VIII, Section 2.9 or otherwise pursuant to this Agreement; (E) to authorize deliveries to the Zephyr Owners of cash from the Escrow

Account once such funds are eligible for distribution therefrom; (F) to establish a reserve in the amount of $250,000.00 from the Merger Consideration with respect to the Zephyr Owners based upon their respective Zephyr Owner Percentage, to fund potential expenses of the Owner Representative in carrying out its authorized duties hereunder (the “Owner Representative Reserve”); (G) on behalf of the Zephyr Owners, to initiate or to refrain from initiating or to dispute or to refrain from disputing any indemnity or other claim under this Agreement and the Ancillary Agreements, as the Owner Representative, in its reasonable discretion, determines to be necessary or desirable; (H) on behalf of the Zephyr Owners, to negotiate, compromise and resolve any dispute which may arise under this Agreement or the Ancillary Agreements, as the Owner Representative, in its reasonable discretion, determines to be necessary or desirable; (I) on behalf of the Zephyr Owners, to exercise or refrain from exercising remedies available under this Agreement and the Ancillary Agreements and to sign any release or other document with respect to such dispute or remedy, as the Owner Representative, in its reasonable discretion, determines to be necessary or desirable; (J) to consent or agree to any amendment to this Agreement or the Ancillary Agreements, as the Owner Representative, in its reasonable discretion, determines to be necessary or desirable; (K) to execute and deliver waivers and consents in connection with this Agreement and the Ancillary Agreements as the Owner Representative, in its reasonable discretion, determines to be necessary or desirable; and (L) to take all actions necessary or appropriate in the reasonable discretion of the Owner Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any Zephyr Owner, and (ii) agrees to be bound by all agreements and determinations made by and documents executed and delivered by the Owner Representative pursuant to the authority granted to it hereunder. The Owner Representative shall have no duties or responsibilities except those expressly set forth in this Agreement and the Letter of Transmittal.

(c) After appointment by the Zephyr Owners, the Owner Representative will be authorized to act on a Zephyr Owners behalf, notwithstanding any dispute or disagreement between any Zephyr Owner and the Owner Representative, and each Indemnified Party and any other Person shall be entitled to rely on any and all actions taken by the Owner Representative under this Agreement without any liability to, or obligation to inquire of, any of the Zephyr Owners. Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Owner Representative that is within the scope of the Owner Representative’s authority under this Section 10.12 shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all the Zephyr Owners and shall be final, binding and conclusive upon each such Zephyr Owner. Each Indemnified Party and any other Person shall be entitled to rely upon any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such Zephyr Owner.

(d) The Owner Representative may resign at any time upon written notice to the Buyer Parties and by providing the Buyer Parties with the name of the successor Owner Representative as designated by action of the Zephyr Owners who hold a majority of the Zephyr Owner Percentage. If for any reason no successor has been appointed pursuant to the foregoing within sixty (60) days, then the Buyer Parties shall have the right to appoint a successor (which successor shall be independent of the Buyer Parties and their Affiliates).

(e) The authorizations of the Owner Representative shall be effective until its rights and obligations under this Agreement terminate by virtue of the termination of any and all obligations of the Owner Representative and the Buyer under this Agreement.

(f) The Buyer Parties shall be entitled to deal exclusively with, and rely upon the authority of, the Owner Representative to act as the agent of the Zephyr Owners.

10.13 Specific Performance. The Parties recognize that in the event that the Companies or the Owner Representative should refuse to perform under the provisions of this Agreement, monetary damages alone will not be adequate. The Buyer Parties shall therefore be entitled to seek, in addition to any other remedies which may be available, including money damages, and without requirement by the Zephyr Owners or the Buyer Parties to post bond or prove actual damages have resulted or would result in the absence thereof, to obtain specific performance of the terms of this Agreement. In the event of any action to enforce this Agreement specifically, the Companies and the Owner Representative hereby waive the defense that there is an adequate remedy at law.
