If Sellers notifies Purchaser that they disagree with any aspect of the Allocation Schedule, Purchaser and Sellers shall work together in good faith to resolve any such disagreement. If any dispute regarding the Allocation Schedule remains unresolved after forty five (45) days following Purchaser’s delivery of such Allocation Schedule to Sellers, then such disagreement shall be immediately submitted to the Independent Accounting Firm, which shall be instructed to resolve such disagreement within thirty (30) days after such disagreement is submitted to it for resolution and shall notify Purchaser and Sellers in writing of its resolution. The Independent Accounting Firm’s resolution of the disagreement shall be final and binding on Purchaser and Sellers. Purchaser and Sellers shall file all Tax Returns (including IRS Form 8594) in a manner consistent with the agreed upon or final Allocation Schedule and neither Purchaser nor Sellers shall take any position (whether in Tax Proceedings, on Tax Returns, or otherwise) that is inconsistent with such Allocation Schedule except as may be adjusted by subsequent agreement following an audit by the Internal Revenue Service or by court decision. In the event the Base Purchase Price is adjusted pursuant to Section 2.06 or Article IX, Purchaser shall promptly prepare and deliver to Sellers an updated Allocation Schedule reflecting such adjustment, and any Sellers’ disagreement with such adjustment shall be resolved in the same manner as a disagreement over the original Allocation Schedule. If incurred, any fees and expenses of the Independent Accounting Firm shall be borne fifty percent (50%) by Purchaser and fifty percent (50%) by Sellers.

Section 6.03 Tax Matters.

(a) Tax Returns

(i) Tax Reporting. Purchaser and Sellers shall, for federal income Tax purposes (and, to the extent permissible, for state and local income Tax purposes), treat the purchase and sale of the Interests pursuant to this Agreement as the purchase and sale of the assets of the Companies, and shall report the purchase and sale on all such income Tax Returns consistently with such treatment.

(ii) Seller Income Tax Returns. Sellers shall include or cause to be included in their federal income Tax Returns (and to the extent permissible, state and local income Tax Returns) that include the income and activities of such Seller all items of income, gain, loss, deduction and credit or other items of the Companies through the Closing Date.

(iii) Purchaser Tax Returns. Following the Closing, Purchaser shall cause to be timely filed all Tax Returns required to be filed by each Company after the Closing Date, and shall be responsible for the timely payment of all Taxes shown due thereon, subject to reimbursement by Sellers pursuant to Section 6.03(e).

(b) Cooperation. Purchaser and Sellers shall cooperate fully, and shall cause their respective Affiliates to cooperate fully, as and to the extent reasonably requested by either Party, in connection with the filing of Tax Returns pursuant to this Section 6.03 and any audit, litigation or other proceeding (each a “Tax Proceeding”) with respect to such Tax Returns. Such cooperation shall include (upon a Party’s request) the provision of records and information which are reasonably relevant to any such Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser shall within fifteen (15) days of receipt notify Sellers in writing of the receipt by Purchaser or any affiliate of Purchaser (including the Companies following the Closing Date) of written notice of any inquires, claims, assessments, audits or similar events with respect to Taxes relating to a Taxable period ending on or prior to the Closing Date. Purchaser agrees to retain all original Books and Records related to Taxes or Tax matters until the fourth anniversary of the Closing Date.

(c) Transfer Taxes. In the event that any Transfer Taxes (but, for the avoidance of doubt, not any Taxes based on or measured by income) are payable in connection with the sale of the Interests, all such Transfer Taxes shall be borne by Purchaser. Accordingly, if Sellers are required by law to pay any such Transfer Taxes, Purchaser shall promptly reimburse Sellers within five (5) Business Days of receipt of written request from Sellers for the amount of such Transfer Taxes actually paid by Sellers. Sellers and Purchaser shall timely file any Tax Returns for Transfer Taxes as required by law and shall notify the other when such filings have been made. Sellers and Purchaser shall cooperate and consult with each other prior to filing any Tax Returns for Transfer Taxes to ensure that all such Tax Returns are filed in a consistent manner. Notwithstanding the foregoing, Sellers shall file all Tax Returns required to be filed in conjunction with the transfer of the Owned Real Property and Purchaser shall be solely liable for and shall pay all Colorado real property Transfer Taxes related thereto and shall indemnify, defend and hold harmless Sellers and their respective Affiliates from and against any and all liability for the payment of such Colorado real property Transfer Taxes and the filing of such Tax Returns related thereto. Purchaser shall reimburse Sellers for any Colorado real property Transfer Taxes actually paid by Sellers within five (5) Business Days of receipt of written request from Sellers therefor.

(d) Tax Sharing or Similar Agreement. Any Tax sharing or similar agreement between a Company on the one hand and a Seller or an Affiliate of Sellers on the other hand shall terminate as of the Closing Date, and no party thereto shall have any rights or obligations thereunder with respect to any past, current or future Tax period.

(e) Reimbursement of Certain Taxes. Any Tax (other than Transfer Taxes that are the subject of Section 6.03(c)) with respect to the property or operations of a Company that are due and payable with respect to any Tax period that begins on or before the Closing Date and ends after the Closing Date (a “Straddle Period”) will be apportioned between the portion of the Straddle Period that ends on the Closing Date (the “Pre-Closing Straddle Period”) and the portion of the Straddle Period that begins on the day after the Closing Date (the “Post-Closing Straddle Period”) as follows: (i) in the case of any ad valorem real estate and personal property Taxes, on a per diem basis and (ii) in the case of any sales Taxes, use or similar Taxes, excise Taxes, value added Taxes and withholding Taxes, as determined from the books and records of each Company as though the taxable period of each Company terminated at the close of business on the Closing Date. Sellers shall reimburse and pay over to Purchaser the amount of any Taxes due and payable with respect to a Pre-Closing Straddle Period within thirty (30) days of receipt of written request from the Purchaser therefore (but in no case earlier than five (5) Business Days prior to the date on which the relevant Taxes are required to be paid to the relevant Tax authority), except to the extent such Taxes were taken into account for purposes of computing Adjusted Net Working Capital.

(f) Refunds. Any Tax refund (including any interest in respect thereof) received by Purchaser or the Companies, and any amounts of overpayments of Tax credited against Taxes which Purchaser, the Companies or any Affiliate thereof otherwise would be or would have been required to pay that relate to Taxes attributable to any Pre-Closing Tax Period or Pre-Closing Straddle Period shall be for the account of Sellers, and

Purchaser shall pay over to Sellers any such refund or the amount of any such credit within thirty (30) days after receipt or the application of any such refund or credit to reduce a Tax liability of Purchaser, the Companies or any Affiliate thereof, except to the extent such Tax refund was taken into account in the calculation of the Adjusted Net Working Capital.

Section 6.04 Public Announcements. Sellers and Purchaser shall not, without prior written consent of the other party, issue any press release or make any public statement with respect to this Agreement and the transactions contemplated hereby except as may be required by applicable Law or any listing agreement with a national securities exchange or quotation system, and will consult with each other before issuing, and provide each other a reasonable opportunity to review and make reasonable comment upon such press release or public statement.

Section 6.05 Expenses and Fees. Except as expressly provided otherwise herein, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the Party incurring such expenses.

Section 6.06 Agreement to Cooperate; Regulatory Approval.

(a) Subject to the terms and conditions of this Agreement and applicable Law, each Party shall use its commercially reasonable efforts to take, or cause to be taken, all action and do, or cause to be done, all things necessary, proper or advisable to obtain as promptly as reasonably practicable all necessary or appropriate waivers, consents, approvals or authorizations of Governmental Authorities and to satisfy all other conditions required in order to consummate the transactions contemplated by this Agreement (and, in such case, to proceed with the consummation of the transactions contemplated by this Agreement as expeditiously as possible).

(b) In addition to and without limitation of the foregoing, Purchaser, on the one hand, and each Seller, on the other hand, shall file as soon as practicable, but in no event later than forty-five (45) days following the Execution Date, any application, form or report required by any Governmental Authority to be filed prior to Closing relating to antitrust, competition, trade or energy regulation matters. Each of the Parties shall request expedited treatment of any such filings and shall (i) respond as promptly as practicable to any inquiries or requests received from any Governmental Authority for additional information or documentation, (ii) not enter into any agreement with any Governmental Authority not to consummate the transactions contemplated by this Agreement, except with the prior consent of the other Party (which shall not be unreasonably withheld, delayed or conditioned), (iii) subject to Section 6.06(c), provide the other Party with a copy of any proposed filing, or amendment or supplement thereto, with any Governmental Authority concerning this Agreement or the transactions contemplated hereby for their review, except any such filing, amendment or supplement that will not become a matter of public record, (iv) provide status updates to the other Party in respect of any filings, investigation or inquiry concerning this Agreement or the transactions contemplated hereby, as may be required by the other Party from time to time, except in respect of any such filing, investigation or inquiry that is not a matter of public record, and (v) at such Party’s sole discretion, consult with the other Party in advance of or following its participation in any in-person, substantive meeting with any Governmental Authority in respect of any filings, investigation or inquiry concerning this Agreement or the transactions contemplated hereby, and it being understood that any such consultation with the other Party shall not constitute, or be construed as constituting, the undertaking of an obligation to solicit or obtain the consent or approval of the other Party.

(c) Prior to filing any application, form or report required by FERC with respect to the transactions contemplated by this Agreement, Purchaser and Sellers, as the case may be, shall provide each other a copy of such proposed filing for their review (except any such proposed filing that will not become a matter of public record), provided that the Parties shall cooperate in the preparation of, and have the joint right to approve, any such application, form or report that must be submitted jointly by Sellers and Purchaser prior to filing.

(d) The application, form or report required by CPUC to be filed with respect to the transactions contemplated by this Agreement shall request CPUC approval of (i) the purchase of the applicable Interests by Purchaser pursuant to the terms and conditions of this Agreement, (ii) the liquidation of the Companies, and the transfer to Purchaser (including transfer by merger) of all of the assets and liabilities of the Companies,

immediately after the Closing, and (iii) the placement of the assets of the Companies into Purchaser’s utility rate base and interim rate relief for Purchaser to recover the revenue requirements associated with such assets, either through a Purchase Capacity Cost Adjustment rider or through an alternative recovery mechanism, until such assets are actually reflected in the setting of Purchaser’s base rates. Sellers shall provide, and shall cause the Companies to provide, such assistance to Purchaser as Purchaser may reasonably request in connection with obtaining such CPUC approvals.

(e) The application, form or report required by FERC to be filed with respect to the transactions contemplated by this Agreement shall state that the consummation of the transactions contemplated by this Agreement will have no effect (or a neutral effect) on market concentration within all relevant markets and that no further action, condition or obligation is required to satisfy the requirements under Section 203 of the Federal Power Act and applicable FERC regulations for approval for the consummation of the transactions contemplated by the Agreement.

(f) Purchaser shall bear the filing fees associated with any filings made pursuant to this Section 6.06.

Section 6.07 Further Assurances. Subject to the terms and conditions of this Agreement, at any time or from time to time after the Closing, at any Party’s request and without further consideration, the other Parties shall execute and deliver to such Party such other instruments of sale, transfer, conveyance, assignment and confirmation, provide such materials and information and take such other actions and execute and deliver such other documents as such Party may reasonably request in order to consummate the transactions contemplated by this Agreement.

Section 6.08 Post-Closing Access to Information. After the Closing Date, each Seller and Purchaser shall grant each other (or their respective designees), and Purchaser shall cause such Company to grant to each Seller (or its designees), access at all reasonable times to all of the information, books and records relating to the Companies and the Facilities in its possession, and shall afford such Party the right (at such party’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to implement the provisions of, or to investigate or defend any Claims arising under, this Agreement. Further, after the Closing Date, Purchaser shall cause such Company to grant to each Seller (or its designees) the access and right to take extracts and make copies described in the preceding sentence for such other purposes as such Seller may reasonably request. Without limiting the foregoing, for a period of twenty-four (24) months after the Closing Date, Sellers shall use commercially reasonable efforts to promptly furnish Purchaser with such Excluded Electronic Records as Purchaser may reasonably request from time to time.

Seller agrees to update such list from time to time and as of the Closing Date. Prior to the Closing Date, Purchaser or its designee shall interview all Operator Facility Employees, who are “actively at work” as of the Execution Date (for purposes of this Section 6.09 an employee is not “actively at work” if the employee is receiving disability benefits under any plan or program established or maintained by Operator for any reason, including the employee having represented that he or she is unable to perform any work). Purchaser, or its designee, shall have the right, but not the obligation, to offer employment (effective as of the Closing Date) to any, all or none of the Operator Facility Employees to perform services at the Facilities.

Purchaser or its Affiliate shall be solely responsible for compliance with the requirements of Section 4980B of the Code and part 6 of subtitle B of Title I of ERISA (“COBRA”), including the provision of continuation coverage with respect to all Affected Employees, and their spouses and dependents, for whom a qualifying event occurs on or after the Closing Date. For purposes of this Section 6.09(b), the terms “continuation coverage’ and “qualifying event” shall have the meanings ascribed to them in COBRA.

(c) Nothing in this Section 6.09 or elsewhere in this Agreement is intended to confer upon any Affected Employee or other Operator Facility Employee any rights of any kind whatsoever under or by reason of this Agreement, including but not limited to any rights to or of employment for a specified period or any other form of employment security, or a right to participate in, or to continue to participate in, any employee benefit plan or program. Purchaser shall not assume any obligation or liability for employment practices or policies maintained by the Operator with respect to Operator Facility Employees. Purchaser and its Affiliates shall not assume any Benefit Plan and shall have no liability or obligation with respect to the Benefit Plans. In addition, Purchaser shall have no obligation or liability nor incur any cost or expense with respect to any claims, whether arising before, on or after the Closing, by any employee or former employee, director or consultant of the Operator arising by reason of the sale or purchase of the Interests in the Companies pursuant to this Agreement or by reason of such employee or former employee’s, director’s or consultant’s employment or service, or the termination of his or her employment or service, by or with such Operator. Without limiting the generality of the foregoing, Operator shall honor and pay all unused vacation, holiday, sickness and personal days accrued prior to the consummation of the Closing by the Affected Employee under the policies and practices of such employer.

Section 6.10 Resignation of Members, Managers, Officers and Directors. At the Closing, such Seller shall cause the resignation of all officers and directors or similar persons on any board or operating, management or other committee established under such Company’s Charter Documents.

Section 6.11 Use of Certain Names. Within fifteen (15) days following the Closing, Purchaser shall cause such Company to cease using the word “Calpine” and any word or expression similar thereto or constituting an abbreviation or extension thereof (the “Sellers’ Marks”), including eliminating the Sellers’ Marks from all assets of the Companies and the disposing of any unused stationery and literature of the Companies, and thereafter, Purchaser shall not, and shall cause the Companies and the Facilities not to, use the Sellers’ Marks or any logos, trademarks, trade names, patents or other Intellectual Property rights belonging to Sellers or any of their Affiliates, or which Sellers or any of their Affiliates have the right to use, and Purchaser acknowledges that it, its Affiliates, the Companies and the Facilities have no rights whatsoever to use such Intellectual Property.

Section 6.12 Support Obligations. At the Closing, Purchaser shall effect the full and unconditional release of Sellers and their Affiliates from any credit support obligations provided by Sellers or such Affiliates with respect to the Companies, the Facilities or the operation thereof, including the credit support obligations listed on Schedule 6.12.

Section 6.13 Termination of Certain Services, Contracts, Receivables and Payables. Notwithstanding anything in this Agreement to the contrary, during the Interim Period, Sellers shall take such actions as may be necessary to terminate or sever as to the Companies or the Facilities (with appropriate mutual releases) upon the Closing any services jointly shared or used by any of the Companies, the Facilities and Sellers or any of their Affiliates, including joint Tax services, joint legal services and joint banking services (to include the severance of any centralized clearance accounts) operation and maintenance services including each Contract listed on Schedule 6.13.

Section 6.14 Insurance. Purchaser shall be solely responsible for providing insurance to such Company and the business of such Facility as of the Closing. Purchaser acknowledges that no insurance coverage or

policy maintained for the Companies or the Facilities will extend beyond the Closing for the benefit of Purchaser. For at least twenty-four (24) months following Closing, Purchaser shall provide insurance no less favorable than the coverage set forth in Schedule 6.14, to the extent available on commercially reasonable terms.

Section 6.15 Title Evidence. Prior to the Execution Date, Purchaser has been provided commitments for an ALTA owner’s title insurance policy in respect of the Owned Real Property (collectively the “Title Evidence”). Prior to the Execution Date, Purchaser shall have notified Sellers of any matters contained in the Title Evidence that would constitute a Lien that is not a Permitted Lien or Purchaser’s failure to so notify Sellers shall be deemed a waiver as of the Execution Date by Purchaser of any right not to close or any right to indemnification pursuant to Article IX following the Closing, as the case may be, by virtue of any matters shown by the Title Evidence. In the event that new or additional Liens are added by an updated title commitment thereto prior to the Closing Date which are not Permitted Liens, Purchaser may make objections thereto in writing within five (5) Business Days following receipt of such updated commitment by Purchaser and Purchaser’s failure to so object shall be deemed a waver of Purchaser’s right to object to such new or additional Liens. Sellers shall use commercially reasonable efforts to cure or remove prior to Closing all said Liens which are not Permitted Liens to which Purchaser shall have objected.

Section 6.16 Fall 2010 RMEC Outage.

(a) [***].

(b) Purchaser shall have the right to observe the Fall 2010 RMEC Outage Work, subject to Section 6.01(b) hereof.

Within two (2) Business Days after its receipt of a Sellers’ Additional Maintenance and Repair Work Notice, Purchaser shall notify Rocky Mountain Seller in writing as to whether it does or does not regard such work as Discovery Work. If Rocky Mountain Seller and Purchaser do not agree as to whether such work is Discovery Work, a dispute shall be deemed to exist and shall be immediately referred to the Independent Engineer, who shall be instructed to determine whether any or all of such work is Discovery Work. The determination of the Independent Engineer shall be final and binding on the Parties, and the cost of the Independent Engineer shall be shared equally by the Parties.

(d) Discovery Work shall be completed as follows:

(i) Discovery Work that is capable of being completed during the RMEC Outage Work Period shall be completed during such period.

(ii) Upon the determination by Rocky Mountain Seller of any Discovery Work that is not capable of being completed within the RMEC Outage Work Period, Rocky Mountain Seller shall notify Purchaser in writing (“Sellers’ Incomplete Discovery Work Notice”) of (1) such Discovery Work and (2) whether it does or does not regard such work as Essential Discovery Work. Within two (2) Business Days after its receipt of a Sellers’ Incomplete Discovery Work Notice, Purchaser shall notify Rocky Mountain Seller in writing as to whether it does or does not regard such Discovery Work as Essential Discovery Work. If Rocky Mountain Seller and Purchaser do not agree as to whether such Discovery Work is Essential Discovery Work, a dispute shall be deemed to exist and shall be immediately referred to the Independent Engineer, who shall be instructed to determine whether any or all of such Discovery Work is Essential Discovery Work. The determination of the Independent Engineer shall be final and binding on the Parties, and the cost of the Independent Engineer shall be shared equally by the Parties. The RMEC

Outage Work Period shall be extended as reasonably necessary to accommodate Rocky Mountain Seller’s completion of any Essential Discovery Work.

(iii) [***].

In the event that the time required to complete Essential Discovery Work under clause (ii) of this Section 6.16(d) extends beyond the Termination Date, Sellers shall be entitled to reasonable extensions of the Termination Date, not to exceed [***] in the aggregate, in order to complete such work.

(b) Subject to the provisions of this Article IX, Purchaser from and after the Closing Date shall indemnify and hold harmless Sellers from and against any and all Losses actually incurred by Sellers that arise out of or result from the breach of any of Purchaser’s (i) representations and warranties contained in this Agreement or in any agreement, instrument or other document delivered in connection herewith, as of the date when made, and (ii) covenants or agreements contained in this Agreement or in any agreement, instrument or other document delivered in connection herewith.

(c) The total aggregate liability of Sellers for any claims for Losses arising under Section 9.02(a) shall not exceed [***] of the Final Purchase Price, except that (i) the total aggregate liability of Sellers for any claims for Losses resulting from (1) the breach of or inaccuracy in any of the representations or warranties set forth in Section 3.01 (Organization and Qualification), Section 3.02 (Authority), Section 3.03 (No Conflicts; Consents and Approvals), Section 3.04 (Ownership of Interests), Section 4.01 (Organization and Qualification), Section 4.02 (No conflicts; Consents and Approvals), Section 4.03 (Subsidiaries; No Other Business), the fourth sentence of Section 4.07(a)(ii) (Assets — Real Property), Section 4.07(b)(ii) (Assets — Other Property — Title to Material Non-Real Estate Assets), Section 4.08 (Employee Benefit Plans), Section 4.09 (Labor and Employment Matters), Section 4.15 (Brokers), and Section 4.16 (Capital Structure) (collectively the “Specified Representations”), and (2) the breach of any covenant or other obligation contained in this Agreement or any other agreement, instrument or other document delivered in connection herewith, shall not, in the aggregate, exceed [***] of the Final Purchase Price and (ii) there shall be [***] on the liability of Sellers for any claims for Losses resulting from the breach of or inaccuracy in any of the representations or warranties set forth in Section 4.12 (Taxes) or from the breach of any of the covenants set forth in Section 6.03 (Tax Matters) or from the Surviving Credit Agreement Indemnities and related Losses, the Surface Use Agreement Losses or the XXXX 0000 Emissions Losses indemnified in Section 9.02(a)(iii).

The Parties shall treat any indemnification payment pursuant to this Article IX as an adjustment to the Final Purchase Price for all Tax purposes unless otherwise required by applicable Law. The Indemnified Party shall use its commercially reasonable efforts to seek insurance recoveries in respect of losses to be indemnified hereunder. If any insurance proceeds or other recoveries from third-parties or net Tax benefits are actually realized (in each case net of expenses of such recoveries) by an Indemnified Party subsequent to the receipt by such Indemnified Party of an indemnification payment hereunder in respect of the claims to which such insurance proceedings, third-party recoveries or net Tax benefits relate, appropriate refunds shall be made promptly to the Indemnifying Party regarding the amount of such indemnification payment.

Section 9.03 Right to Specific Performance; Certain Limitations. Notwithstanding anything in this Agreement to the contrary:

(a) Without limiting or waiving in any respect any rights or remedies of a Party under this Agreement now or hereafter existing at law in equity or by statute, each of the Parties hereto shall be entitled to specific performance of the obligations to be performed by the other Party in accordance with the provisions of this Agreement; and

(b) Except as otherwise provided under the Seller Guaranty, no Representative, Affiliate of, or direct or indirect equity owner in, any Seller shall have any personal liability to Purchaser or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Sellers in this Agreement, and no Representative, Affiliate of, or indirect equity owner in, Purchaser shall have any personal liability to any Seller or any other Person as a result of the breach of any representation, warranty, covenant, agreement or obligation of Purchaser in this Agreement; and

(c) No Party shall be liable for special, punitive, exemplary, incidental, consequential or indirect damages, or lost profits or losses calculated by reference to any multiple of earnings before interest, tax, depreciation or amortization (or any other valuation methodology) whether based on contract, tort, strict liability, other Law or otherwise and whether or not arising from the other Party’s sole, joint or concurrent negligence, strict liability or other fault for any matter relating to this Agreement and the transactions contemplated hereby.

Section 9.04 Procedures for Indemnification. Whenever a Claim shall arise for indemnification under Section 9.02, the Person entitled to indemnification (the “Indemnified Party”) shall promptly notify in writing the Party from which indemnification is sought (the “Indemnifying Party”) of such Claim and, when known, the facts constituting the basis of such Claim, provided that in the event of a Claim for indemnification resulting from or in connection with a Claim by a third party, the Indemnified Party shall give such written notice thereof to the Indemnifying Party not later than ten (10) Business Days prior to the time any response to the third party Claim is required, if possible, and in any event within fifteen (15) Business Days following receipt of notice thereof (provided, that failure to timely notify the Indemnifying Party shall not relieve the Indemnifying Party of any liability it may have to the Indemnified Party, except to the extent that the Indemnifying Party has been actually prejudiced by such failure). Following receipt of notice of any such third party Claim, and unless counsel to the Indemnified Party shall have reasonably determined in good faith that the assumption of such defense by the Indemnifying Party would be inappropriate due to a conflict of interest, the Indemnifying Party shall have the option, at its cost and expense, to assume the defense of such matter and to retain counsel (not reasonably objected to by the Indemnified Party) to defend any such claim or legal proceeding, and the Indemnifying Party shall not be liable to the Indemnified Party for any fees of other counsel or any other expenses (except as expressly provided to the contrary herein) with respect to the defense of such Claim, other than reasonable fees and expenses of counsel employed by the Indemnified Party for any period during which the Indemnifying Party has not assumed the defense thereof. The Indemnified Party shall have the option of joining the defense of such Claim (which shall be at the sole cost and expense of the Indemnified Party) with its own counsel and counsel for each Party shall, to the extent consistent with such counsel’s professional responsibilities, cooperate with the other Party and any counsel designated by that Party. In effecting the settlement or compromise of, or consenting to the entry of any judgment with respect to, any such Claim, the Indemnifying Party, or the Indemnified Party, as the case may be, shall act in good faith, shall consult with the other Party and shall enter into only such settlement or compromise or consent to the entry of any judgment as the other Party shall consent, such consent not to be unreasonably withheld, conditioned or delayed. An Indemnifying Party shall not be liable for any settlement, compromise or judgment not made in accordance with the preceding sentence.

With respect to matters arising from circumstances first occurring after the date of this Agreement or as to which a Party first acquires knowledge after the date of this Agreement, Sellers and Purchaser shall have the right to make any changes or additions to the Schedules (such changes or additions being referred to as “Supplemental Disclosure”) that may be necessary to correct any matter that would otherwise constitute a breach of any representation or warranty in this Agreement. Sellers agree to advise Purchaser promptly in writing of any matter or occurrence of which either of the Sellers has or obtains knowledge, and Purchaser agrees to advise each of the Sellers promptly in writing of any matter of which Purchaser has or obtains knowledge, that, in either case, would reasonably be expected to constitute a breach by such Party of any representation, warranty or covenant contained in this Agreement.

Any disputes or claims arising out of or in connection with this Agreement and the transactions contemplated or documents required hereby shall be submitted to the exclusive jurisdiction of the courts of the State of New York and the federal courts of the United States of America located in the State of New York, County of New York, and appropriate appellate courts therefrom. Each of the Parties hereto acknowledges and agrees that any controversy which may arise under this Agreement is likely to involve complicated and difficult issues, and therefore each such Party hereby irrevocably and unconditionally waives any right such Party may have to a trial by jury in respect of any litigation directly or indirectly arising or relating to this Agreement or the transactions contemplated by this Agreement. The Parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any objection which they may now or hereafter have to the laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of inconvenient forum for the maintenance of such dispute. Each of the Parties hereto agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This consent to jurisdiction is being given solely for purposes of this Agreement and the transactions contemplated hereunder, and is not intended to, and shall not, confer consent to jurisdiction with respect to any other dispute in which a Party to this Agreement may become involved. Each of the Parties hereto hereby consents to process being served by any Party to this Agreement in any suit, action, or proceeding of the nature specified in this Section 10.05 by the mailing of a copy thereof in the manner specified by the provisions of Section 10.01.

Section 10.06 Counterparts. This Agreement may be executed in two (2) or more counterparts, and by facsimile, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement.

Section 10.08 Entire Agreement. This Agreement and the Confidentiality and Non-Disclosure Agreement constitute the entire agreement between the Parties with respect to the subject matter hereof and supersede all prior agreements, understandings and negotiations, both written and oral, between the Parties with respect to the subject matter of this Agreement. No representation, inducement, promise, understanding, condition or warranty not set forth herein has been made or relied upon by any Party. Neither this Agreement nor any provision hereof is intended to confer upon any person other than the Parties hereto any rights or remedies hereunder except as expressly provided otherwise in Section 6.01(b) and Article IX.
