The Estimated Financial Statements shall be prepared in accordance with GAAP (applied using the same principles and policies used to prepare the Balance Sheet and the March 31 Calculations). The parties acknowledge and agree that the calculations of Aggregate Net Company Indebtedness, Adjusted Net Working Capital and the Net PP&E Amount attached to Section 2.2(a) of the Seller Disclosure Schedule are calculations of such amounts as of March 31, 2008 and have been derived from the Balance Sheet (such calculations are referred to herein as the “March 31 Calculations”)

(b) The Base Purchase Price shall be subject to adjustment on the Closing Date as follows (it being understood and agreed that, if applicable, the adjustments contemplated by clauses (i), (ii), (iii) and (iv) immediately below shall be netted against each other for purposes of determining the adjustment to the Base Purchase Price to be made on the Closing Date):

(i) If the Estimated Adjusted Net Working Capital is less than the Target Adjusted Net Working Capital, the Base Purchase Price shall be decreased by an amount equal to the amount by which the Target Adjusted Net Working Capital exceeds the Estimated Adjusted Net Working Capital. If the Estimated Adjusted Net Working Capital is greater than the Target Adjusted Net Working Capital, the Base Purchase Price shall be increased by an amount equal to the amount by which the Estimated Adjusted Net Working Capital exceeds the Target Adjusted Net Working Capital;

(ii) If the Estimated Aggregate Net Company Indebtedness is less than the Target Aggregate Net Company Indebtedness, the Base Purchase Price shall be increased by an amount equal to the amount by which the Target Aggregate Net Company Indebtedness exceeds the Estimated Aggregate Net Company Indebtedness. If the Estimated Aggregate Net Company Indebtedness is greater than the Target Aggregate Net Company Indebtedness, the Base Purchase Price

shall be decreased by an amount equal to the amount by which the Estimated Aggregate Net Company Indebtedness exceeds the Target Aggregate Net Company Indebtedness;

(iii) If the Estimated Net PP&E Amount is less than the Target Net PP&E Amount, the Base Purchase Price shall be decreased by an amount equal to the amount by which the Target Net PP&E Amount exceeds the Estimated Net PP&E Amount. If the Estimated Net PP&E Amount is greater than the Target Net PP&E Amount, the Base Purchase Price shall be increased by an amount equal to the amount by which the Estimated Net PP&E Amount exceeds the Target Net PP&E Amount; and

(iv) The Base Purchase Price shall be decreased by the positive amount obtained by subtracting (A) the sum of $1,000,000 plus the income tax effected aggregate amount (62%) of the SERP Accrual for each Excluded SERP Employee, from (B) $3,700,000 (the amount obtained by subtracting clause (A) from clause (B) is referred to herein as the “Aggregate SERP Adjustment Amount”), it being understood and agreed that Purchaser shall not have the right to dispute Seller’s calculation of the Aggregate SERP Adjustment Amount except in the case of mathematical error.

(c) Within thirty (30) days after the Closing Date, Purchaser shall prepare and deliver to Seller (i) an unaudited balance sheet of the Company as of the close of business on the earlier of November 30, 2008 or the Closing Date, and after giving effect to the completion of the transactions contemplated by Section 5.10(b) hereof (the “Closing Balance Sheet”), and (ii) a statement (the “Closing Adjustment Statement” and, together with the Closing Balance Sheet, the “Closing Date Financial Statements”), which Closing Adjustment Statement shall set forth (x) the Aggregate Net Company Indebtedness, (y) the Adjusted Net Working Capital and (z) the Net PP&E Amount, in each case as of the close of business on the earlier of November 30, 2008 or the Closing Date (and after giving effect to the completion of the transactions contemplated by Section 5.10(b) hereof), with such amounts being derived from the Closing Balance Sheet. The Closing Date Financial Statements shall be prepared in accordance with GAAP (applied using the same principles and policies used to prepare the Balance Sheet and the March 31 Calculations). Contemporaneously with the delivery of the Closing Date Financial Statements, Purchaser shall also deliver to Seller copies of the calculations that Purchaser used in preparing the Closing Date Financial Statements and Purchaser shall also promptly provide to Seller such other calculations, documents and information as Seller may reasonably request for the purpose of verifying the accuracy of the Closing Date Financial Statements. Without limiting the foregoing, Purchaser shall allow Seller and its Representatives reasonable access to the books and records of the Company to the extent reasonably necessary to review and verify the information contained in the Closing Date Financing Statements.

(d) In the event that Seller either has no objections to the Closing Date Financial Statements as prepared by Purchaser and does not deliver a Dispute Notice to Purchaser or if Seller otherwise fails to deliver a Dispute Notice to Purchaser within the time period required by the immediately following sentence, then, on the date that is thirty-one (31)

days following the date on which Purchaser delivers the Closing Date Financial Statements to Seller, the Closing Date Financial Statements prepared by Purchaser, including the Aggregate Net Company Indebtedness, Adjusted Net Working Capital and Net PP&E Amount set forth therein, shall be deemed to be and shall become final, binding and conclusive on the parties hereto, including Seller. In the event that Seller disputes the amount of Aggregate Net Company Indebtedness, the amount of Adjusted Net Working Capital and/or the Net PP&E Amount as set forth in the Closing Date Financial Statements, Seller shall, within thirty (30) days following the date on which Purchaser delivers the Closing Date Financial Statements to Seller, prepare and deliver to Purchaser a written notice of dispute (the “Dispute Notice”), which Dispute Notice shall specifically identify, and provide a reasonably detailed explanation of the basis upon which Seller has delivered such Dispute Notice.

(e) In the event Seller timely delivers a Dispute Notice to Purchaser in accordance with the terms hereof, Purchaser and Seller shall attempt to reconcile their differences, and any resolution by them as to any such disputes shall be final, binding and conclusive on each of them. If Purchaser and Seller are unable to resolve any such dispute within fifteen (15) days of Purchaser’s receipt of the Dispute Notice from Seller, Purchaser and Seller shall submit the items remaining in dispute for resolution to an independent accounting firm of national reputation that is mutually acceptable to Purchaser and Seller (the “Independent Accounting Firm”), provided that if Purchaser and Seller are unable to agree on a mutually acceptable Independent Accounting Firm, then the parties shall request that the New York City, New York office of the American Arbitration Association (the “AAA”) select an accounting firm to as the Independent Accounting Firm hereunder, provided that any such Independent Accounting Firm selected by the AAA shall be of national reputation and shall (i) not be an Affiliate of Seller or Purchaser, (ii) not have had a material business relationship with Seller or Purchaser in the two (2) year period immediately preceding the proposed engagement of such Independent Accounting Firm and (iii) have expertise in general accounting matters. Upon the selection of the Independent Accounting Firm, and in any event within five (5) Business Days following such selection, Purchaser and Seller shall submit to such Independent Accounting Firm (and the other party) all documentary materials and analyses that Purchaser or Seller, as the case may be, believes to be relevant to a resolution of the dispute set forth in the Dispute Notice and, without limiting the foregoing, Purchaser shall allow the Independent Accounting Firm and its Representatives reasonable access to the books and records of the Company to the extent reasonably necessary to perform the duties for which it is engaged hereunder. The Independent Accounting Firm shall, within twenty (20) Business Days after receipt of all such submissions by Purchaser and Seller, determine and deliver to Purchaser and Seller a written report (the “Final Report”) containing such Independent Accounting Firm’s determination of the disputed matters that were so submitted to it (and only such matters), and the determinations of the Independent Accounting Firm that are contained therein shall be final, binding and conclusive on Purchaser and Seller. The fees and disbursements of the Independent Accounting Firm and, if applicable, the AAA, shall be allocated to Seller in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by Seller (as finally determined by the Independent Accounting Firm) bears to the total amount of such remaining disputed items so submitted, and the balance shall be paid by Purchaser.

(f) No later than two (2) Business Days following the Determination Date, Seller or Purchaser, as the case may be, shall make the following payments, after netting against each other all payments required to be made by Seller and/or Purchaser, as the case may be, pursuant to clauses (i), (ii) and (iii) immediately below, with all such payments being made to the applicable Person via wire transfer of immediately available funds to the account or accounts designated in writing by the Person entitled to receive such payment:

(i) If the Estimated Adjusted Net Working Capital is less than the Final Adjusted Net Working Capital, Purchaser shall pay to Seller an amount equal to the amount by which the Final Adjusted Net Working Capital exceeds the Estimated Adjusted Net Working Capital. If the Estimated Adjusted Net Working Capital is greater than the Final Adjusted Net Working Capital, Seller shall pay to Purchaser an amount equal to the amount by which the Estimated Adjusted Net Working Capital exceeds the Final Adjusted Net Working Capital;

(ii) If the Estimated Aggregate Net Company Indebtedness is less than the Final Aggregate Net Company Indebtedness, Seller shall pay to Purchaser an amount equal to the amount by which the Final Aggregate Net Company Indebtedness exceeds Estimated Aggregate Net Company Indebtedness. If the Estimated Aggregate Net Company Indebtedness is greater than the Final Aggregate Net Company Indebtedness, Purchaser shall pay to Seller an amount equal to the amount by which the Estimated Aggregate Net Company Indebtedness exceeds the Final Aggregate Net Company Indebtedness; and

(iii) If the Estimated Net PP&E Amount is less than the Final Net PP&E Amount, Purchaser shall pay to Seller an amount equal to the amount by which the Final Net PP&E Amount exceeds Estimated Net PP&E Amount. If the Estimated Net PP&E Amount is greater than the Final Net PP&E Amount, Seller shall pay to Purchaser an amount equal to the amount by which the Estimated Net PP&E Amount exceeds the Final Net PP&E Amount.

(g) Any amount paid pursuant to Section 2.3(f) shall bear interest from the Closing Date through but excluding the date of payment, at a rate of eight percent (8%) per annum. Such interest shall accrue daily on the basis of a three hundred sixty (360) day year calculated for the actual number of days for which payment is due and such payment shall be payable together with the amount payable pursuant to Section 2.2(f).

Purchaser shall, or shall cause the Company to, perform all of the obligations under the Company Plans as in effect on the Closing Date or as may thereafter be amended in accordance with the terms hereof and thereof. Without limiting the foregoing, Purchaser shall, or shall cause the Company to, adopt a severance plan effective at the Closing in a form reasonably satisfactory to Seller and having the terms set forth on Section 5.2(a) of the Seller Disclosure Schedule (the "Company Severance Plan"), it being understood and agreed that notwithstanding anything contained in the first sentence of this Section 5.2(a) to the contrary, Purchaser shall maintain, or cause the Company to maintain, the Company Severance Plan in accordance with the term thereof as set forth in Section 5.2(a) of the Seller Disclosure Schedule. The parties acknowledge and agree that for purposes of this Section 5.2, Company Plans shall include the Company SERP and the Company Severance Plan.

(b) At or prior to the Closing, Seller shall create a new deferred compensation/salary reduction plan (the "Seller Deferred Compensation Plan") for executives

Except as expressly set forth in the immediately preceding sentence, all deferred compensation liabilities and obligations under the Company Deferred Compensation Plan shall remain obligations of the Company.

(c) At or prior to the Closing Date, the Company shall create and, subject to the terms set forth in this Section 5.2, including Section 5.2(a) hereof, maintain, a supplemental retirement plan, substantially in the form attached to Section 5.2(c) of the Seller Disclosure Schedule and approved by Purchaser, such approval not to be unreasonably withheld, conditioned or delayed (the "Company SERP "). At or prior to the Closing Date, any and all liabilities under the Intermountain Industries, Inc. Supplemental Retirement Plan (other than liabilities thereunder that are associated with an Excluded SERP Employee, Xxxxxxx X. Xxxxx, Xxxxxxx Xxxxx and Xxxxxxx Xxxxx) shall be transferred to, and become liabilities of, the Company pursuant to the Company SERP, and, without limiting the terms set forth in Section 2.2(b)(iv) hereof, neither Seller nor any of its post-Closing Affiliates shall have any liability or obligations in respect thereof.

At and after the Closing, all such participants that are Company Employees shall be eligible to participate in a defined contribution plan maintained by Purchaser (the “Purchaser Savings Plan” ) on terms, for at least one (1) year following the Closing, that are substantially similar in the aggregate to those that applied to such participants under the Company Savings Plans immediately prior to the Closing. Upon receipt by the Company of a favorable IRS determination letter with respect to the termination of the Company Savings Plans, Purchaser shall allow the Purchaser Savings Plan to accept direct rollovers for participants from the Company Savings Plans.

(e) Purchaser shall, or shall cause its Affiliates, as applicable, to give Company Employees full credit for such Company Employees' service with the Company and its Affiliates for purposes of eligibility, vesting, and determination of the level of benefits (including for purposes of vacation and severance), but not for purposes of benefit accruals, under any benefit plans made generally available to employees or officers or any class or level of employees or officers maintained by Purchaser or any of its Affiliates in which a Company Employee participates to the same extent recognized by the Company or an Affiliate thereof

immediately prior to the Closing; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits with respect to the same period of service.

(f) Purchaser shall, or shall cause its Affiliates, as applicable, to (i) waive any preexisting condition limitations otherwise applicable to Company Employees and their eligible dependents under any plan of Purchaser or any Subsidiary of Purchaser that provides health benefits in which Company Employees may be eligible to participate following the Closing, other than any limitations that were in effect with respect to such Company Employees as of the Closing under the analogous Company Plan, (ii) honor any deductible, co-payment and out-of-pocket maximums incurred by the Company Employees and their eligible dependents under the health plans in which they participated immediately prior to the Closing during the portion of the calendar year prior to the Closing in satisfying any deductibles, co-payments or out-of-pocket maximums under health plans of Purchaser or any of its Affiliates in which they are eligible to participate after the Closing in the same plan year in which such deductibles, co-payments or out-of-pocket maximums were incurred and (iii) waive any waiting period limitation or evidence of insurability requirement that would otherwise be applicable to a Company Employee and his or her eligible dependents on or after the Closing, in each case to the extent such Company Employee or eligible dependent had satisfied any similar limitation or requirement under an analogous Company Plan prior to the Closing.

(g) The provisions of this Section 5.2 (other than in respect of the Company Severance Plan) are solely for the benefit of the parties to this Agreement, and except with respect to the provisions regarding the Company Severance Plan, no employee or former employee of the Company or any other individual associated therewith shall be regarded for any purpose as a third party beneficiary of this Agreement, and nothing herein shall be construed as an amendment to any Company Plan for any purpose. The parties acknowledge and agree that nothing contained in this Agreement, including in this Section 5.2, shall require Purchaser or any Affiliate thereof (including, after the Closing Date, the Company) to maintain the employment of any employee of the Company.

Section 5.3 Publicity. Purchaser and Seller agree that no public release or announcement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of Purchaser and Seller (which consent shall not be unreasonably withheld, delayed or conditioned), except (a) such release or announcement as may be required by applicable Law, in which case, to the extent practicable, the party required to make the release or announcement shall allow the other party reasonable time to comment on such release or announcement in advance of such issuance, (b) Seller and Purchaser shall be permitted to disclose this Agreement and the transactions contemplated hereby in connection with making any Governmental Filing or Purchaser Governmental Filing, as applicable, or in response to the request of any Government Entity having jurisdiction over Purchaser or any of its Subsidiaries, and Seller and Purchaser shall be permitted to take such actions in connection with obtaining or making any other filings, registrations, notifications, authorizations, consents or approvals, in each case in connection with the transactions contemplated by this Agreement, and (c) nothing contained herein shall preclude disclosure of this Agreement or the transactions contemplated hereby in the event of litigation between the parties hereto, but then only to the extent necessary to prosecute or defend any such litigation.

Section 5.4 Confidentiality. Purchaser and its Representatives (as such term is defined in the Confidentiality Agreement between Citigroup Global Markets Inc. (on behalf of the Company) and Purchaser, dated April 7, 2008 (as the same may be amended, modified or supplemented from time to time, the "Confidentiality Agreement")) shall treat all materials and information obtained in connection with this Agreement and the transactions contemplated hereby as confidential in accordance with the terms of the Confidentiality Agreement. If this Agreement is, for any reason, terminated prior to the Closing, the Confidentiality Agreement shall continue in full force and effect in accordance with the terms set forth therein.

Section 5.5 Access to Information. Subject to Section 5.4, Seller shall cause the Company to afford Purchaser and its Representatives reasonable access, during normal business hours and upon reasonable notice, to the officers, properties, offices and other facilities of the Company and to its books and records, and shall furnish Purchaser with available financial, operating and other data and information with respect to the business and properties of the Company as Purchaser may reasonably request. In exercising its rights hereunder, Purchaser shall (and shall cause each of its Representatives to) conduct itself so as not to interfere in the conduct of the business of the Company prior to Closing. Purchaser acknowledges and agrees that any contact by Purchaser or its Representatives with officers, employees, customers or agents of the Company shall be arranged and supervised by representatives of Seller, unless Seller otherwise expressly consents in writing with respect to any specific unsupervised contact. Notwithstanding anything to the contrary set forth in this Agreement, neither Seller nor any of its Affiliates (including the Company) shall be required to disclose to Purchaser or any Representative thereof any information (a) relating to any sale or divestiture process conducted by Seller for the Company or the Business or Seller's (or its Representatives') evaluation of the Company or the Business in connection therewith, including projections, financial information or other information relating thereto or (b) if doing so could violate any Contract or Law to which Seller or any of its Affiliates (including the Company) is a party or to which it is subject or which it believes in good faith could result in a loss of the ability to successfully assert a claim of privilege (including the attorney-client and work product privileges). In addition, notwithstanding anything contained in this Agreement to the contrary, without the prior written consent of Seller, none of Purchaser or its Representatives shall have any right to perform or conduct, or cause to be performed or conducted, any environmental sampling or testing at, in, on or underneath the Real Property.

Neither party shall agree to participate in any meeting, whether in person or telephonically, with any Governmental Entity in respect of filings referred to in this Section 5.6(a) or any investigation or other inquiries relating thereto, unless the relevant party consults with the other party in advance, and to the extent permitted by such Governmental Entity, gives the other party the opportunity to attend and participate thereat.

(b) [Intentionally omitted.]

(c) Seller and/or Purchaser, as applicable, shall, as promptly as reasonably practicable following the date of this Agreement, cause to be filed all applications, reports, notices and other documents, if any, required to be filed by Purchaser and/or Seller or any of their respective Affiliates (including, in the case of Seller, the Company) with any Governmental Entities (other than the filings contemplated by Section 5.6(a) hereof), including (i) the filing of a written notification with the IPUC in such form and containing such information as the IPUC may request from time to time, together with any other applications, reports, notices and other documents that the IPUC may request from time to time (collectively, the “IPUC Notification Filing”), in each case, concerning the transactions contemplated hereby, and (ii) the filing of such applications, reports, notices and other documents, if any, required to be filed by Purchaser or any of its Affiliates in connection with obtaining the consents of the Governmental Entities listed on Part I , Part II or Part III (if applicable, in the case of Part II and Part III) of Exhibit C hereto, which notifications, applications, reports and other documents referred to in the immediately preceding clause (i) shall be in form and substance reasonably satisfactory to each of Seller and Purchaser, and with Seller being provided a reasonable opportunity to review and comment on the foregoing referred to in the immediately preceding clause (ii).

Neither party shall agree to participate in any meeting, whether in person or telephonically, with the IPUC or any investigation or other inquiries relating thereto, unless the relevant party consults with the other party in advance, and to the extent permitted by the IPUC, gives the other party the opportunity to attend and participate thereat.

(d) Purchaser and Seller shall cooperate with one another in determining whether any action by or in respect of, or filing with, any Governmental Entity (excluding the actions and filings described in subsections (a) and (c) of this Section 5.6) is required or reasonably appropriate, or any action, consent, approval or waiver from any party to

any Company Material Contract is required or reasonably appropriate, in connection with the consummation of the transactions contemplated by this Agreement. Subject to the terms and conditions of this Agreement and the Confidentiality Agreement, in taking such actions or making any such filings, the parties shall furnish such information as may be required in connection therewith and timely seek to obtain any such actions, consents, approvals or waivers.

If the Closing occurs, Purchaser and Seller agree that all rights to indemnification and all limitations on liability existing in favor of any individual who, on or prior to the Closing Date, was an officer, director or employee of the Company (collectively, the "Company Indemnitees"), as provided in (a) the articles of incorporation or bylaws of the Company in effect on the date of this Agreement or (b) any agreement providing for indemnification by the Company of any Company Indemnitee in effect on the date of this Agreement to which the Company is a party or by which it is bound as of the date of this Agreement and which in each case of this clause (b) is listed on Section 5.7 of the Seller Disclosure Schedule, shall survive the consummation of the transactions contemplated hereby and continue in full force and effect and be honored by the Company after the Closing for a period of not less than six (6) years. Purchaser shall cause the Company to take all actions required by, and otherwise comply with, the provisions of this Section 5.7.

In addition, but subject to the terms set forth in the immediately following sentence, Seller agrees to use its reasonable best efforts to assist Purchaser in obtaining a waiver or amendment, as appropriate, to Section 9.17 of the Debenture Purchase Agreement to permit Purchaser to include the Company in its consolidated income Tax returns, and to permit the Company to make tax payments as part of Purchaser’s consolidated group in the same

manner as currently provided for in such Section 9.17 with respect to Seller.

Notwithstanding the foregoing, upon written notice to Seller, the Company may bring claims under such policies that are occurrence-based policies for losses that occur prior to the Closing if permitted under such policies, provided that uninsured costs of such claims shall be at the Company's sole cost and expense (including any applicable retentions or deductibles in connection with such claims).

Section 5.10 Indebtedness; Termination of Affiliate Agreements.

(a) Subject to the terms of this Agreement, including the last sentence of Section 5.8 hereof, if Purchaser desires to obtain the consent of the lenders party to the Credit Agreement to waive the change of control provision set forth therein or to assign the Credit Agreement, Seller agrees to cooperate with any reasonable request of Purchaser in connection with Purchaser’s seeking and obtaining such consent. However, if such consent has not been obtained, on the Closing Date, Purchaser shall repay, or shall cause one of its Affiliates to repay, any and all amounts that are outstanding on the Closing Date, whether principal, accrued and unpaid interest or otherwise, under the terms of the Credit Agreement, and Seller and Purchaser shall, at the Closing, cause the administrative agent or other lenders, as applicable, under the Credit Agreement to deliver written evidence thereof to the parties hereto. Seller acknowledges and agrees that all amounts that are outstanding on the Closing Date, whether principal, accrued and unpaid interest or otherwise, under the terms of the Credit Agreement, and that are repaid by Purchaser as contemplated by this Section 5.10(a) shall constitute Debt for purposes of calculating the amount of Aggregate Net Company Indebtedness hereunder. Notwithstanding anything contained in this Agreement to the contrary, Purchaser acknowledges and agrees that any and all amounts that are outstanding on the Closing Date, whether principal, accrued and unpaid interest or otherwise, under the terms of the Debenture Purchase Agreement shall remain outstanding upon the Closing and shall not be repaid or otherwise extinguished at the Closing, provided that all such amounts shall constitute Debt for purposes of calculating the amount of Aggregate Net Company Indebtedness hereunder.

(b) Effective at the Closing, except for those Contracts set forth in Section 5.10(b)(i) of the Seller Disclosure Schedule, all Contracts between the Company, on the one hand, and Seller or any of its Affiliates, on the other hand (the "Terminating Contracts"), shall be terminated as between them and shall be without any further force and effect, and there shall be no further obligations of any of the relevant parties thereunder. Purchaser agrees to take and to cause the Company to take, and Seller agrees to take and to cause its Affiliates (other than the Company) to take, any action following the Closing that would be required to give effect to the termination of the Terminating Contracts. Without

limiting the foregoing, except as set forth in Section 5.10(b)(ii) of the Seller Disclosure Schedule, all inter-company accounts, whether payables or receivables, between any of Seller and its Affiliates, on the one hand, and the Company, on the other hand, as of the Closing shall be settled in cash or otherwise discharged and released as of the Closing.

Section 5.11 Names. Following the Closing Date, the Company shall be permitted to continue to use the name “Intermountain Gas Company” and any other name, trademark or service xxxx used by the Company in the operation of the Business as of the Closing Date and that is listed on Section 5.11 of the Seller Disclosure Schedule (such name and such other names, trademarks and service marks are collectively referred to herein as the “Marks”), provided that Purchaser shall cause the Company to use the Marks solely in connection with the operation of the Business, it being understood and agreed that neither Purchaser nor any of its Affiliates (including, after the Closing Date, the Company) shall be permitted to use any of the Marks in connection with any other activities. Without limiting the foregoing, Purchaser shall not, and shall cause its Affiliates (including, after the Closing Date, the Company) not to, (a) hold itself out as having any affiliation or relationship of any kind with Seller or any post-Closing Affiliate thereof, provided that Purchaser shall be permitted, and may permit its Affiliates (including, after the Closing Date, the Company) to refer to the fact that the Company was purchased from Seller or (b) use the Marks in a manner that would be reasonably likely to reflect negatively thereon or on Seller or its post-Closing Affiliates. Purchaser shall, and shall cause the Company to, indemnify and hold harmless Seller and its post-Closing Affiliates from and against any Losses relating to or arising from any use by Purchaser or the Company of the Marks in a manner not permitted by this Section 5.11 or otherwise. Notwithstanding anything contained in this Agreement to the contrary, Seller and its post-Closing Affiliates shall be permitted to use the Marks (other than the name “Intermountain Gas Company” or any other Xxxx that is used exclusively in the Business as of the date hereof) in connection with the operation of any business or activities in which they may be engaged from time to time, provided that Seller shall not, and shall cause its post-Closing Affiliates not to, hold itself out as having any affiliation or relationship of any kind with the Company, provided that Seller shall be permitted to, and may permit its post-Closing Affiliates to, refer to the fact that the Company was previously owned by Seller. Without limiting the foregoing, Seller shall not use the Marks in a manner that would be reasonably likely to reflect negatively thereon or on the Company or its post-Closing Affiliates. Seller shall indemnify and hold harmless Company and its post-Closing Affiliates from and against any Losses relating to or arising from any use by Seller or its post-Closing Affiliates of the Marks in a manner not permitted by this Section 5.11.

Section 5.12 Tax Matters.

(a) Seller shall timely prepare and file, or cause to be timely prepared and filed, on a basis consistent with past practice to the extent consistent with applicable Law, all Tax Returns with respect to the Company for any Tax period of the Company ending on or prior to the Closing Date (the “Pre-Closing Tax Returns”). With respect to all income Tax Returns (other than income Tax Returns filed on a consolidated, combined or unitary basis with Seller or any of Seller’s Affiliates) and other material Pre-Closing Tax Returns that are filed by Seller after the Closing Date, Seller shall permit Purchaser to review and comment on each such Tax Return prior to its filing and Seller shall make such revisions to such Tax Returns as are reasonably requested by Purchaser as long as such revisions are consistent with the prior

practices of the Company that are consistent with applicable Law. In connection with Purchaser’s review, Seller shall provide any and all financial data that is reasonably necessary to confirm the correctness of any such Tax Returns. Seller shall deliver a copy of each Pre-Closing Tax Return (or the portion thereof that specifically related to the Company) to Purchaser promptly after filing. Seller shall timely pay or cause to be timely paid all Taxes due with respect to the Pre-Closing Tax Returns to the extent that such Taxes exceed the amount (if any) of such Taxes that are included as current liabilities in Adjusted Net Working Capital, as finally determined pursuant to Section 2.2 of this Agreement. Notwithstanding anything herein to the contrary, no position shall be taken, election made, or method adopted on any Pre-Closing Tax Return that (i) is inconsistent with positions taken, elections made or methods used in preparing or filing similar Tax Returns in the immediately prior period, or (ii) would reasonably be expected to materially and adversely affect the Tax position or liability of Purchaser, the Company or any of their Affiliates for any period following the Closing Date (including, without limitation, positions, elections or methods that would have the effect of deferring income to Tax periods (or portions thereof) ending after the Closing Date or accelerating deductions to Tax periods (or portions thereof) ending on or prior to the Closing Date), in case of either clause (i) or this clause (ii), without the prior written consent of the Purchaser, which consent shall not be unreasonably withheld, conditioned or delayed. Purchaser shall timely prepare and file, or cause to be timely prepared and filed, on a basis consistent with past practice to the extent consistent with applicable Law, all Tax Returns for any Straddle Period of the Company (“Straddle Period Tax Returns”). Purchaser shall permit Seller to review and comment on each Straddle Period Tax Return prior to its filing and Purchaser shall make such revisions to such Straddle Period Tax Returns as are reasonably requested by Seller as long as such revisions are consistent with the prior practices of the Company that are consistent with applicable Law. In connection with Seller’s review, Purchaser shall provide any and all financial data that is reasonably necessary to confirm the correctness of any such Tax Returns. Purchaser shall deliver a copy of each such Tax Return to Purchaser promptly after filing.

(b) All tax-sharing or similar agreements with respect to or involving the Company shall be terminated as of the Closing Date and after the Closing Date, the Company shall not be ound thereby or have any liability thereunder. Seller may elect to control, at its own expense, the conduct of any audit or administrative or judicial proceeding with respect to any Taxes of, or any Tax Return required to be filed by, the Company with respect to any Pre-Closing Tax Period for which Seller is liable for indemnification pursuant to Section 8.1, if Seller acknowledged in writing that Seller has sole responsibility for any Taxes that arise in such audit or proceeding; provided, however, that Seller shall not resolve, abandon, compromise or settle any such audit or proceeding without obtaining Purchaser's prior written consent (which consent may not be unreasonably withheld, conditioned or delayed) if it would reasonably be expected to have a materially adverse effect on Purchaser, the Company or any Affiliate thereof; provided further, however, that (i) Seller shall keep Purchaser reasonably apprised of the status of the audit or proceeding, and (ii) Purchaser shall have the right, at its own expense, to retain separate counsel and to reasonably participate (but not control) in the aspects of the prosecution or defense of such Tax audit or proceeding that are reasonably anticipated to materially adversely affect the Taxes of Purchaser or any of its Affiliates with respect to any Tax period ending after the Closing Date.

(c) Purchaser and Seller shall cooperate fully, as and to the extent reasonably requested by the other party, in connection with the filing of Tax Returns and any audit, litigation or other proceeding with respect to Taxes of the Company. Such cooperation shall include the retention and (upon the other party's request) the provision of records and information reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser and Seller shall retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until expiration of the statute of limitations on assessment (taking into account any extensions thereof) of the respective taxable periods. Seller shall provide reasonable prior written notice to Purchaser prior to disposing of books and records with respect to Tax matters pertinent to the Company, at Purchaser’s request, shall provide Purchaser with copies of all such books and records with respect to Tax matters pertinent to the Company.

(d) Neither Purchaser nor any of its Affiliates (including after the Closing, the Company) shall, without the prior written consent of Seller (which consent shall not be unreasonably withheld, delayed or conditioned), (i) make or change any Tax election affecting a taxable period ending on or before the Closing Date of Seller or any of its Affiliates (including, before the Closing, the Company), (ii) amend, refile or otherwise modify (or grant an extension of any applicable statute of limitations on assessment with respect to) any Tax Return prepared by Seller or any of its Affiliates (including, before the Closing, the Company) relating to a taxable period ending on or before the Closing Date or (iii) take any action that results in any increased Tax liability (including a reduction in a refund) or reduction of any Tax asset of the Company (or Seller or any of its Affiliates) in respect of a taxable period ending on or before the Closing Date.

(e) If, following the Closing Date, a refund of Taxes (the "Refund") is received by or credited to the account of the Company in respect of any Pre-Closing Tax Period or of Pre-Closing Straddle Period Taxes, Purchaser shall cause the Company to pay the amount of the Refund to Seller to the extent such Refund exceeds the amount (if any) of such Refund that is included as a current asset in Adjusted Net Working Capital, as finally determined pursuant to Section 2.2 of this Agreement.

Section 5.13 Non-Solicitation of Employees. For a period of one (1) year from and after the Closing, Seller shall not, and shall cause each of its post-Closing Affiliates not to, directly or indirectly, for its own account or for the account of any other Person, knowingly encourage, solicit or induce, or in any manner attempt to knowingly encourage, solicit or induce, any Person employed by the Company as of the Closing Date to terminate such Person's employment with the Company. Notwithstanding the foregoing, nothing contained in the immediately preceding sentence shall preclude Seller or its post-Closing Affiliates from (i) making a general solicitation for employment contained in a newspaper or other periodical or on the radio, internet or similar media or hiring any employee of the Company as a result thereof or (ii) taking any actions otherwise prohibited pursuant to the terms of the immediately preceding sentence if the Person subject thereto has initiated discussions with Seller or any of its post-Closing Affiliates without any knowing encouragement, solicitation or inducement by Seller or such post-Closing Affiliates. Seller and Purchaser acknowledge that the restrictions contained in this Section 5.13 are reasonable in scope and duration in light of the nature, size and location of

the Business. Seller and Purchaser further acknowledge that the restrictions contained in this Section 5.13 are necessary to protect Purchaser's significant investment in the Business, including its goodwill. If any court of competent jurisdiction shall at any time deem the duration or scope of any of the provisions of this Section 5.13 to be unenforceable, the other provisions of this Section shall nevertheless stand and the duration and/or scope set forth herein shall be deemed to be the longest period and/or greatest size permissible by Law under the circumstances, and the parties hereto agree that such court shall reduce the time period and/or scope to permissible duration or size.

Section 5.14 Purchaser's Financing Activities.

(a) Purchaser acknowledges and agrees that, except as otherwise set forth in this Agreement, Seller and its Affiliates shall have no responsibility for any financing that Purchaser may raise or attempt to raise in connection with the transactions contemplated hereby. Any offering memorandum, banker's book or other materials prepared by or on behalf of Purchaser or its Affiliates, or Purchaser's financing sources, in connection with Purchaser's financing activities in connection with the transactions contemplated hereby (collectively, "Offering Materials") which include any information provided by or on behalf of Seller or any of its Affiliates (including the Company) shall include a conspicuous disclaimer to the effect that neither Seller nor any of its Affiliates (other than the Company only after the Closing Date) nor any employees thereof have any responsibility for the content of such Offering Materials and disclaim all responsibility therefor and shall further include a disclaimer with respect to Seller and its Affiliates (other than the Company only after the Closing Date) in any oral disclosure with respect to such financing activities.

(b) Seller shall provide, and shall cause the Company to provide, and shall use its commercially reasonable efforts to cause the respective officers, employees, Representatives and advisors (including legal and accounting advisors) of Seller and its Affiliates (including the Company) to provide, to Purchaser all reasonable and customary cooperation requested by Purchaser in connection with any debt or equity financing that Purchaser may determine to obtain prior to the Closing, in each case upon the reasonable request of Purchaser with reasonable prior notice. Purchaser shall promptly, upon request by Seller, reimburse Seller for all reasonable and documented out-of-pocket expenses incurred by Seller or its Representatives in connection with such cooperation.

(d) by Seller or Purchaser, by written notice to the other, if there shall be a final Law in effect making illegal the consummation of the transactions contemplated hereby, or there shall be a Governmental Order that is a Final Order in effect prohibiting the consummation of the transactions contemplated hereby or that would cause the condition set forth in Section 6.1 (a), (c) or (d) not to be satisfied; provided, however, that the right to terminate this Agreement under this Section 7.1(d) shall not be available to such party if the failure of such party to fulfill any obligation under this Agreement shall have been the cause of, or shall have resulted in, the enactment of such Law or the issuance of such Governmental Order;

Section 7.2 Effect of Termination. In the event of termination of this Agreement by a party pursuant to Section 7.1, written notice thereof shall forthwith be given by the terminating party to the other party, and this Agreement shall thereupon terminate and become void and have no effect, and the transactions contemplated hereby shall be abandoned without further action by the parties, except that the provisions of Sections 5.4, 9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 9.10 and 9.13 and this Section 7.2 shall survive the termination of this Agreement; provided, however, that, if such termination shall have been caused by, or shall have resulted from, the intentional and material breach by a party of any of its representations, warranties, covenants or agreements set forth in this Agreement, including, in the case of Purchaser, Purchaser's failure to pay any portion of the Closing Date Purchase Price upon the satisfaction or waiver of the applicable conditions to Closing set forth in Article VI, Seller, on the one hand, or Purchaser, on the other hand, as the case may be, shall be fully liable for any and all Losses of the other party as a result of such breach or failure.

damages or expenses, including reasonable attorneys’ fees (collectively, “Losses”), that any Purchaser Indemnified Party has suffered, sustained, incurred or become subject to and that arises out of: (a) the breach of any of the representations and warranties of Seller contained in Article III of this Agreement, provided that Losses arising out of any breach of any of the representations and warranties contained in Section 3.4 (Governmental Filings), clause (ii) of Section 3.8(i), Section 3.9 (Legal Proceedings), 3.10 (Compliance with Laws), Section 3.12 (Taxes) and Section 3.14(d) (Employee Benefit Plans) shall be determined without giving effect to any “Material Adverse Effect” or other materiality qualification contained in such representations and warranties; (b) the breach of any covenant or agreement of Seller set forth in this Agreement; (c) all Losses incurred by any Purchaser Indemnified Party in respect of Taxes of Seller or any member of an Affiliated Group of which the Company is a part for any Pre-Closing Tax Period of the Company pursuant to Treasury Regulations Section 1.1502-6 (or analogous state or local Tax law); (d) all Losses incurred by any Purchaser Indemnified Party in respect of Taxes with respect to any Pre-Closing Tax Period and for any Pre-Closing Straddle Period Taxes, except to the extent that the Taxes set forth in clauses (c) and (d) are included as current liabilities in Adjusted Net Working Capital, as finally determined pursuant to Section 2.2 of this Agreement; and (e) all uninsured liability arising out of the pending litigation brought by plaintiffs Xxxxxx X.

Subject to the terms and conditions of this Article VIII, including, without limitation, the terms and conditions set forth in Sections 8.6, from and after the Closing Date, Purchaser shall indemnify, defend and hold Seller, its Affiliates, directors, officers, employees, successors and permitted assigns (collectively, the “Seller Indemnified Parties”), harmless from and against any and all Losses that any such Seller Indemnified Party has suffered, sustained, incurred or become subject to and that arises out of: (a) the breach of any of the representations and warranties of Purchaser contained in Article IV of this Agreement; or (b) the breach of any covenant or agreement of Purchaser under this Agreement.

Section 8.3 Survival. The pre-Closing covenants of the parties set forth in this Agreement and the related rights of the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, to indemnity with respect to any breach thereof in accordance with the applicable Sections hereof shall survive the Closing and the consummation of the transactions contemplated by this Agreement until the one (1) year anniversary of the Closing Date unless a shorter period of performance is specified with respect to such covenant. The representations and warranties of the parties contained in this Agreement other than the representations and warranties of Seller set forth in Section 3.2 (Authorization), Section 3.5 (Capital Structure; Subsidiaries), Section 3.12 (Taxes) or Section 3.14 (Employee Benefit Plans), the representations and warranties of Purchaser set forth in Section 4.2 (Authorization), Section 4.8 (Solvency), and Section 4.9 (Foreign Persons), and the related rights of the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, to indemnity with

respect to any breach thereof in accordance with the applicable Sections hereof, shall survive the Closing for a period of eighteen (18) months following the Closing Date. Notwithstanding the foregoing provisions of this Section 8.3, but subject to the other provisions of this Article VIII, the representations and warranties of Seller set forth in (i) Section 3.2 (Authorization), Section 3.5 (Capital Structure; Subsidiaries) and Section 3.12 (Taxes), and the representations and warranties of Purchaser set forth in Section 4.2 (Authorization), Section 4.8 (Solvency) and Section 4.9 (Foreign Persons), and the related rights of the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, to indemnity with respect to any breach thereof in accordance with the applicable Sections hereof, shall survive the Closing until the fourth (4th) anniversary of the Closing Date, and (ii) Section 3.14 (Employee Benefit Plans), and the related rights of the Purchaser Indemnified Parties to indemnity with respect to any breach thereof in accordance with the applicable Sections hereof, shall survive the Closing until the third (3rd) anniversary of the Closing Date. The parties hereto hereby acknowledge and agree that any bona fide claim (and only such bona fide claim, but not the related representations and warranties) for indemnification made in writing in accordance with the terms of this Article VIII on or prior to the applicable expiration date with respect to any such claim as set forth herein shall survive the Closing and any such applicable expiration date until the final resolution thereof.

Section 8.4 Limitation on Liability.

(a) Purchaser (on behalf of itself and the other Purchaser Indemnified Parties) hereby acknowledges and agrees that, except as otherwise provided in the immediately following proviso, no claim for indemnification by a Purchaser Indemnified Party pursuant to the terms of Section 8.1(a) above (an indemnification claim by a Purchaser Indemnified Party pursuant to the terms of Section 8.1(a) above is referred to herein as a “Purchaser Warranty Claim”) shall be asserted by a Purchaser Indemnified Party unless and until (i) the aggregate amount of Losses incurred by the Purchaser Indemnified Parties with respect to the event or occurrence giving rise to such Purchaser Warranty Claim exceeds $100,000 (a “Base Claim”) and (ii) the aggregate amount of all Losses to which all of the Purchaser Indemnified Parties shall be entitled by reason of any and all Purchaser Warranty Claims that constitute Base Claims exceeds, in the aggregate, one percent (1%) of the Closing Date Purchase Price (the “Deductible”), provided that once the Deductible has been exceeded, the Purchaser Indemnified Parties shall be entitled to indemnification for only the amount of Losses in respect of Purchaser Warranty Claims that constitute Base Claims that are in excess of the Deductible; provided, however, that, with respect to a breach of the Excluded Warranties or the representations and warranties contained in clause (ii) of Section 3.8(i) and Section 3.12 (Taxes), the amount of the Base Claim and the amount of the Deductible shall be zero, it being understood and agreed that, subject to the terms set forth in Section 8.4(b), in the case of a breach of the Excluded Warranties, the Purchaser Indemnified Parties shall be entitled to be paid an amount equal to all Losses incurred by them in connection with a breach of such Excluded Warranties as and when such Losses are incurred (and whether or not the Deductible has been exceeded or the Purchaser Warranty Claim constitutes a Base Claim). The parties hereto hereby acknowledge and agree that liability hereunder of any Indemnitor for any Losses shall be limited to the amount of such Losses net of (i) any insurance or other recoveries from third parties (other than Seller or Purchaser, as applicable) payable to the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, in connection with the facts giving rise to the right of

indemnification hereunder and (ii) the present value of the amount of any net Tax Benefits reasonably expected to be realized by the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, as a result of the Losses that the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, have suffered, sustained, incurred or become subject to in connection with the facts giving rise to the right of indemnification hereunder, with such net Tax Benefits to be calculated in good faith by such parties. For purposes of this subsection, “Tax Benefits” means, after utilizing all deductions, credits, and losses otherwise available or reasonably anticipated to be available, any refund of income Taxes paid or an actual reduction in the amount of income Taxes that would otherwise be required or reasonably anticipated to be required to be paid in the particular Tax period.

(b) Notwithstanding anything contained in this Agreement to the contrary, and except as otherwise provided in the immediately following proviso, in no event shall the aggregate amount of Losses paid by Seller to the Purchaser Indemnified Parties arising out of any and all Purchaser Warranty Claims exceed an aggregate amount equal to ten percent (10%) of the Closing Date Purchase Price; provided, however, that the foregoing limitation on the aggregate amount of Losses that arise out of Purchaser Warranty Claims shall not apply to any such Purchaser Warranty Claims arising out of or resulting from a breach of the representations and warranties (collectively, the “Excluded Warranties”) of Seller set forth in Section 3.2 (Authorization) or Section 3.5 (Capital Structure; Subsidiaries), it being understood and agreed that the Purchaser Indemnified Parties shall be entitled to be paid an amount equal to all Losses incurred by them in connection with a breach of such Excluded Warranties, which payments in respect of such Losses, in the aggregate with all other payments by Seller under this Article VIII, shall not exceed one hundred percent (100%) of the Closing Date Purchase Price.

Section 8.5 Notice and Opportunity to Defend. If there occurs an event which any party hereto (or any Purchaser Indemnified Party or any Seller Indemnified Party) asserts is an indemnifiable event pursuant to this Article VIII, the Person or Persons seeking indemnification (collectively, the “Indemnitee”) shall notify in writing the party or parties obligated to provide indemnification pursuant to the terms hereof (collectively, the “Indemnitor”) promptly after obtaining knowledge of the occurrence of such event. If such event involves any claim or the commencement of any action or proceeding by a third Person, the Indemnitee shall give the Indemnitor prompt written notice of such claim or the commencement of such action or proceeding. The notice shall describe the claim, the amount of the claim if known and quantifiable, and the basis therefor, or if not then known, a good faith estimate of the amount thereof and the basis therefor. Any delay or failure by an Indemnitee to so notify the Indemnitor shall relieve the Indemnitor of its indemnification obligations hereunder to the extent that the Indemnitor is prejudiced by reason of such delay or failure. The Indemnitor shall be entitled to assume and control (with counsel of its choice) the defense of such matter at the Indemnitor’s expense by sending written notice to the Indemnitee of its election to do so within thirty (30) days after receiving written notice from the Indemnitee. The Indemnitee agrees to cooperate fully with the Indemnitor and its counsel in the defense against any such asserted claim; provided, however, that neither the Indemnitee nor the Indemnitor shall be required pursuant to this Section 8.5 to disclose any privileged information or any attorney work product in connection with the defense of any such asserted claim. In any event, the Indemnitee shall have the right to participate (but not control) in the defense of such asserted claim with separate counsel, if it desires, at its own expense. Any settlement or compromise of such asserted claim

by the Indemnitor shall require the prior written consent of the Indemnitee, which consent shall not be unreasonably withheld, conditioned or delayed, provided that no such consent shall be required as long as it is solely a monetary settlement that provides a full release of the Indemnitee with respect to such matter and does not contain an admission of liability on the part of the Indemnitee. If the Indemnitor shall not have assumed the defense of such claim within the thirty (30) day period set forth above, the Indemnitee may assume the defense of such claim with counsel of its choice and the Indemnitor shall be required to pay all reasonable costs and reasonable expenses incurred by the Indemnitee in connection with such matter; provided, however, in the event the Indemnitee assumes control of the defense of any such claim as contemplated by this sentence, the Indemnitee shall not be permitted to settle or compromise any such claim without the prior written consent of the Indemnitor, which consent shall not be unreasonably withheld, conditioned or delayed.

Section 8.6 No Knowledge of Breach; Mitigation; Other Indemnification Provisions.

(a) Notwithstanding anything to the contrary contained herein, no party shall make an indemnification claim hereunder with respect to any breach of any representation, warranty, covenant or agreement set forth in this Agreement to the extent that the liability underlying such claim were accounted for in the adjustment to the Base Purchase Price or the Closing Date Purchase Price, as applicable, pursuant to Section 2.2 hereof.

(b) Without limiting the computation of Losses as hereunder as set forth in Section 8.4(a) hereof, to the extent that an Indemnitor makes any payment pursuant to this Article VIII in respect of Losses for which the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, have a right to recover against a third party, the Indemnitor shall, if applicable, after the Purchaser Indemnified Parties have recouped any amounts not paid to them by the Indemnitor, including any amount not recouped as a result of the Deductible, be subrogated to the right of the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, to seek and obtain recovery from such third party at the expense of the Indemnitor; provided, however, that if the Indemnitor shall be prohibited from such subrogation, the Purchaser Indemnified Parties or the Seller Indemnified Parties, as the case may be, shall seek recovery from such third party on the Indemnitor’s behalf and expense and shall, subject to the foregoing in respect of non-indemnified Losses, including the Deductible, pay any such recovery to the Indemnitor, provided that any amount so paid to the Indemnitor shall not exceed the amount of the indemnification payment made by it hereunder.

Section 8.7 Tax Treatment of Indemnification Provisions. The parties agree that any indemnification payments made pursuant to this Agreement shall be treated for Tax purposes as an adjustment to the Final Purchase Price, unless otherwise required by applicable Law.

Section 8.8 Exclusivity. After the Closing, except for the rights of the parties hereunder to specific performance or other equitable relief, except pursuant to Section 2.2 hereof and except in the case of actual fraud, in which case the Purchaser Indemnified Parties and the Seller Indemnified Parties reserve any and all rights and remedies available to them, the indemnities set forth in this Article VIII shall be the exclusive remedies of the Purchaser Indemnified Parties and the Seller Indemnified Parties for any breach of any representation or

warranty or breach of any covenant or agreement contained in this Agreement, and such parties shall not be entitled to a rescission of this Agreement or to any further indemnification rights or claims of any nature whatsoever in respect thereof, all of which Seller (on behalf of the Seller Indemnified Parties) and Purchaser (on behalf of the Purchaser Indemnified Parties) hereby waive to the fullest extent permitted by applicable Law.

Section 9.5 Headings. The headings contained in this Agreement are inserted for convenience only and shall not be considered in interpreting or construing any of the provisions contained in this Agreement.

Section 9.6 Fees and Expenses. Except as otherwise expressly set forth in this Agreement, including in this Section 9.6, each party shall bear its own costs and expenses (including financial advisory and legal fees and expenses) incurred in connection with this Agreement and the transactions contemplated hereby; provided, however, that Purchaser shall be responsible for all Transfer Taxes (as well as the filing of all Tax Returns with respect thereto), and for any fees in connection with any filing pursuant to the HSR Act or any other regulatory filings required to be made by any party hereto in connection with the consummation of the transactions contemplated hereby.

Section 9.7 Entire Agreement. This Agreement (including the Exhibits and Schedules) constitute the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings between the parties with respect to such subject matter; provided, however, that the terms and provisions of the Confidentiality Agreement shall remain in full force and effect until expiration or termination thereof in accordance with its terms, provided that all terms thereof (other than the terms thereof that are applicable to information relating to Seller and its Affiliates (other than the Company)) shall terminate immediately following the Closing.

Section 9.8 Interpretation.

(a) When a reference is made in this Agreement to an Article, Section, Exhibit or Schedule, such reference shall be to an Article, Section, Exhibit or Schedule of or to this Agreement unless otherwise indicated.

(b) Whenever the words "include," "includes" or "including" are used in this Agreement, they shall be deemed to be followed by the words "without limitation."

(c) When a reference in this Agreement is made to a "party" or "parties," such reference shall be to a party or parties to this Agreement unless otherwise indicated.

(d) Unless the context requires otherwise, the terms "hereof," "herein," "hereby," "hereto" and derivative or similar words in this Agreement refer to this entire Agreement.

(e) Unless the context requires otherwise, words in this Agreement using the singular or plural number also include the plural or singular number, respectively, and the use of any gender herein shall be deemed to include the other genders.

(f) References in this Agreement to "dollars" or "$" are to U.S. dollars.

(g) This Agreement was prepared jointly by the parties and no rule that it be construed against the drafter will have any application in its construction or interpretation.

Section 9.9 Seller Disclosure Schedule. Any matter disclosed in any Section of the Seller Disclosure Schedule shall be deemed to be disclosed for all purposes of the Agreement and all other Sections of the Seller Disclosure Schedule set forth herein to the extent that it is reasonably apparent that such disclosure is applicable to such other Sections of the Seller Disclosure Schedule. The inclusion of any information in any Section of the Seller Disclosure Schedule shall not be deemed to be an admission or acknowledgment or otherwise imply that such information is required to be listed in any Section of the Seller Disclosure Schedule or that any such matter rises to a Material Adverse Effect or is material to or outside the ordinary course of business of the Company or the Business (or that any such matter is above any specified threshold). Matters reflected in the Seller Disclosure Schedule are not necessarily limited to matters required by this Agreement to be reflected in the Seller Disclosure Schedule. Such

additional matters are set forth for informational purposes and do not necessarily include other matters of a similar nature. All references in the Seller Disclosure Schedule to the enforceability of agreements with third parties, the existence or non-existence of third-party rights, the absence of breaches or defaults by third parties, or similar matters or statements, are intended only to allocate rights and risks between Purchaser and Seller and are not intended to be admissions against interests, give rise to any inference or proof of accuracy, be admissible against any party to this Agreement by any Person who is not a party to this Agreement, or give rise to any claim or benefit to any Person who is not a party to this Agreement. In addition, the disclosure of any matter in the Seller Disclosure Schedule is not to be deemed an admission that such matter actually constitutes non-compliance with, or a violation of Law, any Permit or Contract or other topic to which such disclosure is applicable. In no event shall the disclosure of matters disclosed in the Seller Disclosure Schedule be deemed or interpreted to broaden Seller's representations and warranties, obligations, covenants, conditions or agreements contained in this Agreement. The headings contained in the Seller Disclosure Schedule are for convenience of reference only and shall not be deemed to modify or influence the interpretation of the information contained in the Seller Disclosure Schedule or this Agreement.

Section 9.10 Waiver and Amendment. This Agreement may be amended, modified or supplemented only by a written mutual agreement executed and delivered by Seller and Purchaser. Except as otherwise expressly provided in this Agreement, any failure of any party to comply with any obligation, covenant, agreement or condition herein may be waived by the party entitled to the benefits thereof only by a written instrument signed by the party granting such waiver, but such waiver or failure to insist upon strict compliance with such obligations, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

Section 9.11 Counterparts; Facsimile Signatures. This Agreement may be executed in any number of counterparts, each of which when executed, shall be deemed to be an original and all of which together shall be deemed to be one and the same instrument binding upon all of the parties notwithstanding the fact that all of the parties are not signatory to the original or the same counterpart. For purposes of this Agreement, facsimile signatures shall be deemed originals.

Section 9.12 Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties and their successors and permitted assigns and nothing herein express or implied shall give or be construed to give to any Person, other than the parties and such successors and permitted assigns, any legal or equitable rights hereunder, except that (a) each Company Indemnitee shall be a third party beneficiary of this Agreement and shall have the right to enforce the obligations of Purchaser pursuant to Section 5.7 hereof and (b) each Company Employee shall be a third party beneficiary of this Agreement and shall have the right to enforce the obligations of Purchaser relating to the Company Severance Plan.

Section 9.13 Specific Performance. The parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, no adequate remedy at Law would exist and damages

would be difficult to determine, and that the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at Law or in equity.

Section 9.14 Severability. If any provision of this Agreement or the application of any such provision to any Person or circumstance shall be held invalid, illegal or unenforceable in any respect by a court of competent jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision hereof.
