FC_i is the actual amount of Fuel consumed by the Dedicated Unit during the hour as measured by the Unit Meter – Fuel in MMBTU; and

GI₁ is the Gas Index applicable to the hour i in $/MMBTU.

(b) For each Hour when such Dedicated Unit is Dispatched at or above Minimum Load, the Maximum Heat Rate Tracking Account balance shall change by the value shown in the following formula:

MaxHRTAB_m = S(MaxHRTAA_i) = S(((MaxGHR_i x StdED_i) + (SuppGHR_ix SuppED_i) – FC_i) x GI_i) where:

MaxHRTAB_m is the Maximum Heat Rate Tracking Account balance for such Month m for each Dedicated Unit;

S means the summation over all hours of the Month m;

MaxHRTAA_i is the Maximum Heat Rate Tracking Account adjustment for the hour i;

MaxGHR_i is the Maximum Guaranteed Heat Rate in MMBTU/MWh at the Net Electrical Output Dispatched and delivered as a percent of the Standard Capacity during the hour i as set forth in Appendix F;

StdED_i is the amount of energy Dispatched by Purchaser and delivered by the Facility as Net Electrical Output up to the Standard Capacity during the hour i in MWh;

SuppGHR_i is the Supplemental Guaranteed Heat Rate in MMBTU/MWh as set forth in Appendix F;

SuppED_iis the amount of energy Dispatched by Purchaser and delivered by the Facility as Net Electrical Output in excess of the rate of the Standard Capacity;

GI₁ is the Gas Index applicable to the hour i in $/MMBTU.

(c) There shall be no Tracking Account adjustment for the Net Electrical Output of a Dedicated Unit operating below Minimum Load during a Start-Up or shut down.

(d)

At the end of each Month, the Guaranteed Heat Rate Payment will be determined as follows:

(i) If the Minimum Heat Rate Tracking Account balance is positive, then the Guaranteed Heat Rate Payment would be paid by Purchaser to Seller and be calculated as follows:

Guaranteed Heat Rate Payment = Minimum Heat Rate Tracking Account Balance * 0.5

(ii) If the Maximum Heat Rate Tracking Account balance is negative, then the Guaranteed Heat Rate Payment would be paid by Seller to Purchaser and be calculated as follows:

Guaranteed Heat Rate Payment = Maximum Heat Rate Tracking Account Balance * -0.5

(iii) Otherwise,

Guaranteed Heat Rate Payment = 0

(iv) result in, or require, the creation or imposition of any mortgage, deed of trust, pledge, lien, security interest, or other charge or encumbrance of any nature (other than as may be contemplated by this Agreement) upon or with respect to any of the assets or properties of Purchaser, the creation or imposition of which could reasonably be expected to have a material adverse effect on the ability of Purchaser to perform its obligations under this Agreement.

(d) This Agreement constitutes a legal, valid and binding obligation of Purchaser and is enforceable against Purchaser in accordance with its terms, except as may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights of creditors generally and except as the enforceability of this Agreement is subject to the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law), including, without limitation, the possible unavailability of specific performance, injunctive relief or any other equitable remedy and concepts of materiality, reasonableness, good faith and fair dealing.

(e) There is no pending or, to the best of Purchaser’s knowledge, threatened action or proceeding affecting Purchaser before any court, Governmental Agency or arbitrator that could reasonably be expected to materially and adversely affect the financial condition or operations of Purchaser or the ability of Purchaser to perform its obligations hereunder, or that purports to affect the legality, validity or enforceability of this Agreement.

Section 14.3 Certificates and Opinions. Each of Purchaser and Seller shall, upon the request of the other Party, deliver or cause to be delivered from time to time to the other Party certifications of its officers, accountants, engineers or agents as to such matters as either Party may reasonably request in connection with such Parties’ obligations under this Agreement.

Section 14.4 Books and Records; Information. Each of Purchaser and Seller shall keep proper books of record and account, in which full and correct entries shall be made of all dealings or transactions of or in relation to its business and affairs in accordance with GAAP consistently applied.

Section 14.5 Guarantee. Subject to Section 14.8, Purchaser’s obligations under this agreement shall be guaranteed by Constellation Energy Group, Inc. through a Guarantee in the form of Appendix G.

Section 14.6 Amendments to Xxxxxxx PPA. Seller acknowledges and agrees that without Purchaser’s prior written consent, Seller shall have no right to agree to or otherwise enter into any amendment or modification to the Xxxxxxx PPA which would materially adversely affect Purchaser’s rights and obligations under this Agreement or, assuming the conditions precedent to the effectiveness of the Assignment and Assumption Agreement were satisfied, Purchaser’s rights and obligations as purchaser under the Xxxxxxx PPA, and Seller agrees to indemnify and hold harmless Purchaser from and against any loss, damage, cost or expense in connection with any unauthorized amendment or modifications to the Xxxxxxx PPA. Seller may amend or modify the Xxxxxxx PPA to the extent such assignment or modification is not otherwise prohibited by this Section 14.6.

Section 14.7 Enforcement of Seller’s Rights under the Xxxxxxx PPA. If at any time during the Term Xxxxxxx is in breach of its obligations under the Xxxxxxx PPA as such event is referenced therein, Seller shall communicate such to Purchaser in accordance with the terms of Section 14.9. Within five (5) Business Days after Seller’s notice, representatives of the Parties shall discuss what course of action, if any, should be taken with respect to such breach subject to the provisions below; provided, however, that Purchaser shall have the right to decide on

the course of action to be taken, subject to satisfaction of the conditions to taking such action set forth in this Section 14.7. Following such discussion, Purchaser may request that Seller enforce its contractual rights under the Xxxxxxx PPA (an “Enforcement Action”). Upon receipt of such notice, Seller shall exercise Commercially Reasonable Efforts to enforce such rights. If Purchaser determines in good faith that it desires that Seller take an Enforcement Action in addition to those that Seller deems to constitute Commercially Reasonable Efforts, it shall notify Seller of the same, and shall specify in writing the specific actions it desires Seller to take (the “Additional Enforcement Action”). Seller agrees to take an Enforcement Action requested by Purchaser if: (a) it reasonably believes that (i) the actions requested of it are rights that it is lawfully permitted to take in the enforcement of its rights under the Xxxxxxx PPA, and (ii) taking the actions requested will not materially and adversely affect other rights that Seller may have under the Xxxxxxx PPA (taking into account to extent to which Seller has provided the benefit of such rights to Purchaser pursuant to this Agreement); and (b) in the case of an Additional Enforcement Action, to the extent permitted by Section 19.3(d) the Purchaser agrees to pay for any costs and expenses reasonably incurred by Seller in taking the Additional Enforcement Action which exceed the costs and expenses of Seller taking Commercially Reasonable Efforts, which shall include reasonable compensation for the value of the material amounts of time which may be required to be expended by Seller’s personnel to take the Additional Enforcement Action. Notwithstanding anything in this Section 14.7 to the contrary, however, Purchaser’s agreement to compensate Seller for costs and expenses incurred in taking the Additional Enforcement Action under clause (b) above shall not preclude Purchaser from claiming that such Additional Enforcement Action did not require Seller to take actions beyond Commercially Reasonable Efforts and seeking reimbursement from Seller for the amounts paid to Seller pursuant to such clause (b) under the other provisions of this Agreement, as well as interest thereon pursuant to Section 13.5.

Section 14.8 Purchaser’s Credit Requirement. If at any time on or after March 1, 2005, the Credit Rating of Purchaser’s Guarantor is below either BBB- from S&P or Baa3 from Xxxxx’x, Purchaser shall be required to post the Collateral Amount of Performance Assurance with Seller no later than 5:00 pm Central Prevailing Time on the Business Day which is two (2) Business Days after Purchaser’s receipt of Seller’s invoice for such Collateral Amount (“Delivery Date”). Upon delivery of the Performance Assurance, Seller shall release the Guarantee described in Section 14.5, and Seller shall return such Guarantee to Purchaser within five (5) Business Days of Seller’s receipt of Purchaser’s written request therefor. The Performance Assurance shall be held by Seller until the earlier of: (i) the date on which Credit Rating of Purchaser’s Guarantor is at least BBB- from S&P and Baa3 from Xxxxx’x and Purchaser has again provided the Guarantee described in Section 14.5, or (ii) the remainder of the Term. Should such Performance Assurance not be received by Seller by the Delivery Date or should the Performance Assurance cease to be in effect during the Term for any reason, this shall constitute an Event of Default with respect to Purchaser pursuant to the terms of Section 18.1(b)(vii).

To secure its obligations under this Agreement (including, but not limited to, the payment by Purchaser of any disputed amounts pursuant to Section 18.3 which are determined to be due) and to the extent Purchaser delivers Performance Assurance hereunder, Purchaser hereby grants to Seller a present and continuing security interest in, and lien on (and right of setoff against), and assignment of, all cash collateral and cash equivalent collateral and any and all proceeds resulting therefrom or the liquidation thereof, whether now or hereafter held by, on behalf of, or for the benefit of Seller pursuant to this Agreement, and Purchaser agrees to take such action as Seller reasonably requires in order to perfect Seller’s first-priority security interest in, and lien on (and right of setoff against), such collateral and any and all proceeds resulting therefrom or from the liquidation thereof. Upon or any time after the occurrence or deemed occurrence and during the continuation of an Event of Default by Purchaser or a termination of the Agreement caused by Purchaser pursuant to Article 18, Seller may do any one or more of the following: (i) exercise any of the rights and remedies of a secured party with respect to all Performance Assurance, including any such rights and remedies under law then in effect; (ii) exercise its rights of setoff against any and all property of the Purchaser in the possession of Seller or its agent; (iii) draw on any outstanding Letter of Credit issued for its benefit; and (iv) liquidate all Performance Assurance then held by or for the benefit of Seller free from any claim or right of any nature whatsoever of Purchaser, including any equity or right of purchase or redemption by Purchaser. Seller shall apply the proceeds of the collateral realized upon the exercise of any such rights or remedies to reduce Purchaser’s obligations under the Agreement (Purchaser remaining liable for any amounts owing to Seller after such application), subject to Seller’s obligation to return any surplus proceeds remaining after such obligations are satisfied in full.

Section 14.9 Communications. In addition to the notices and other communications provided for elsewhere in this Agreement, Seller covenants and agrees that it will use Commercially Reasonable Efforts to promptly provide Purchaser with copies of written communications between Seller and Xxxxxxx which concern the following: (i) the failure by Xxxxxxx to perform any of its material obligations under the Xxxxxxx PPA during the Term of this Agreement, (ii) the administration of the transactions contemplated by the Xxxxxxx PPA during the Term of this Agreement in a manner which is materially different than the terms set forth therein, and (iii) any material dispute between Seller and Xxxxxxx in connection with the Xxxxxxx PPA which either: (A) exists on or after the Effective Date and has not already been communicated to Purchaser as of the Effective Date or (B) occurs during or arises out of the Term of this Agreement.

(a) Seller shall be responsible for the payment of, and the Reservation Payments, Energy Payments, Guaranteed Heat Rate Payments and other amounts payable by Purchaser to Seller hereunder shall not be subject to adjustment for, Taxes (other than Change-in-Law Taxes) imposed on Seller and its property. Purchaser shall be responsible for the payment of, and no amount payable by Seller to Purchaser shall be subject to adjustment for, Taxes imposed on Purchaser and its property. In addition, Purchaser shall be responsible for the payment of any Change-in-Law Taxes imposed on Seller pursuant to the Xxxxxxx PPA; provided, however, that to the extent that the Change-in-Law Taxes pertain to the Term of this Agreement Seller and Purchaser shall use Commercially Reasonable Efforts to jointly pursue an implementation of Section 15.1(a) of the Xxxxxxx PPA (including utilizing the dispute resolution procedures of the Xxxxxxx PPA if necessary) that reflects an equitable allocation of such costs between the Parties. The Parties agree that any adjustments made pursuant to Section 15.1(a) of the Xxxxxxx PPA in accordance with the preceding sentence shall be employed herein as a reasonable allocation of such costs between the Parties. Seller shall determine for any Billing Period the adjustment to any payment under Section 13.1 resulting from the application of a Change-in-Law Tax for such period, and shall provide to Purchaser a certificate setting forth in reasonable detail the basis and calculation of such adjustment. In the case of any Change-in-Law Taxes imposed on Seller for which Purchaser is responsible, Purchaser shall pay Seller the amount of such Taxes within 10 Days of Seller notifying Purchaser of the imposition of such Change-in-Law Taxes and providing Purchaser with a certificate in reasonable detail of the amount of such Change-in-Law Taxes. If, after the imposition of Change-in-Law Taxes in respect of which Purchaser has made a payment to Seller under this Section 15.1(a), a subsequent Change-in-Law results in a reduction of such Change-in-Law Taxes, then the obligation of Purchaser to pay for Change-in-Law Taxes shall be reduced to such extent, and if such Change-in-Law affects Change-in-Law Taxes as to which Purchaser has already made such payments under this Section 15.1(a), Seller shall reimburse Purchaser an amount equal to such reduction in Taxes.

(b) Seller shall provide Purchaser with written notice, as soon as reasonably practicable, but in no event less than 10 Days prior to the date on which Change-in-Law Taxes imposed on Seller would become applicable, of such Change-in-Law Taxes. Purchaser shall have the right to Contest, in the name of either or both Parties, as required, and Seller shall Contest in the name of Xxxxxxx if requested by Purchaser the imposition of any Change-in-Law Taxes, and Purchaser shall make any payments to Seller in respect of such Change-in-Law Taxes when required under this Agreement, but subject to refund in the event that Purchaser or Seller, as applicable, prevails in such Contest; provided that Purchaser shall notify Seller in writing of its decision to Contest; and provided, further, that Purchaser shall be responsible for any costs and expenses (including the costs and expenses of Seller) relating to such Contest.

(c) Each Party shall provide the other Party upon written request a certificate of exemption or other reasonably satisfactory evidence of exemption if any exemption from or reduction of any Tax is applicable. Each Party shall exercise Commercially Reasonable Efforts to obtain and to cooperate in obtaining any exemption from or reduction of any Tax. Each Party shall notify the other Party of any proposal to implement a Change-in-Law Tax.

Section 15.2. Change-in-Law. If the capital or variable costs of the financing, operation or maintenance of the Dedicated Units change as a result of a Change-in-Law, the Reservation Payment, the Energy Payment, the Guaranteed Heat Rate Payment shall be adjusted, as appropriate, to correspond to the amount that such Payments, costs and/or amount were adjusted under Section 15.2 of the Xxxxxxx PPA as of the date that such changed costs were implemented under the Xxxxxxx PPA; provided, however that to the extent that the Change-in-Law pertains to the Term of this Agreement Seller and Purchaser shall use Commercially Reasonable Efforts to jointly pursue an implementation of Section 15.2 of the Xxxxxxx PPA (including utilizing the dispute resolution procedures of the Xxxxxxx PPA if necessary) that reflects an equitable allocation of such costs between the Parties. The Parties agree that any adjustments made pursuant to Section 15.2 of the Xxxxxxx PPA in accordance with the preceding sentence shall be employed herein as a reasonable allocation of such costs between the Parties. Seller shall not be entitled to a Change in Law cost increase to the extent caused by Seller’s failure to comply with Section 5.4(b). Seller shall submit to Purchaser a certificate setting forth in reasonable detail the basis of and the calculation for, such adjustments. Within 10 Days after its receipt of such certificate, Purchaser shall notify Seller whether it approves or disapproves of Seller’s adjustments, If Purchaser approves of such adjustments within such 10 Day period or the adjustments shall be determined to be due Seller by dispute resolution, the adjustments shall become effective under this Agreement.

(a) the non-performing Party shall give the other Party written notice within 48 hours of the commencement of the Force Majeure Event, with details to be supplied within 10 Days after the commencement of the Force Majeure Event further describing the particulars of the occurrence of the Force Majeure Event after such commencement the non-performing party shall be excused for breach or liability for any delay or failure in its performance hereunder;

(a) If any Force Majeure Event claimed by a Party shall continue for more than twelve Months from the date of notice provided by such Party in Section 17.2(a), the Parties shall attempt to mutually agree as to whether such termination right should be exercised. If the Parties are unable to agree within thirty (30) Days after such right of termination arose, Seller shall have the exclusive right to elect whether to terminate this Agreement which shall be evidenced by written notice to Purchaser specifying such as well as the date of termination. Other than the payment of any costs and liabilities incurred prior to the effective date of such termination, both Parties agree that neither Party shall have any liability to the other as a result of the termination of this Agreement pursuant to this Section 17.3.

(b) To the extent that Seller is unable to deliver all or part of the Actual Contract Capacity of a Dedicated Unit as a result of a Force Majeure Event claimed by Seller in accordance with Section 17.2, as to that Dedicated Unit to the extent that the Actual Contract Capacity is not available as a result of such Force Majeure Event; Purchaser’s payments of the Reservation Payment (the “Force Majeure Fixed Payments”) shall be reduced for the period of Force Majeure in accordance with the following formula:

PC means the total amount of Contract Capacity multiplied by the number of hours for the period.

The foregoing shall not affect the obligation of Purchaser to pay Seller the Reservation Payment for Replacement Power or any other payment obligation of Purchaser. Subject to the foregoing, if Purchaser shall be unable to accept the Actual Contract Capacity or Net Electrical Output as a result of a Force Majeure Event claimed by Purchaser, Purchaser shall remain obligated to pay the Reservation Payment to Seller pursuant to Section 10.1 and any other payments due under the Agreement for the period of such Force Majeure Event.

Section 18.2 Financing Party’s Opportunity to Cure. Should an Event of Default under this Agreement occur with respect to Seller which is caused, directly or indirectly, by Xxxxxxx pursuant to the terms of the Xxxxxxx PPA, Purchaser agrees that Purchaser will not exercise any rights arising from such Event of Default until the cure period allotted to the Financing Parties as described in Section 18.2 of the Xxxxxxx PPA has elapsed and such Event of Default remains uncured. The Parties agree, however, that notwithstanding the prior sentence, during the continuance of any such Event of Default, Purchaser may also withhold payments due to Seller hereunder, to the extent that this Agreement would otherwise give Purchaser that right, in which case Seller may similarly elect not to make the resulting payments due to Xxxxxxx under the Xxxxxxx PPA (a “Resulting Non Payment”). Purchaser agrees that Purchaser’s rights to withhold such payments under the preceding sentence shall terminate on the date which is the earlier of: (a) the date on which such Event of Default is no longer continuing in effect or (b) the date on which Purchaser receives notice from Seller that Seller has received a notice from Xxxxxxx pursuant to Section 18.1(b) of the Xxxxxxx PPA as a result of the Resulting Non Payment. Once Purchaser’s right to withhold payment expires in accordance with the previous sentence, such withheld payment shall be due and payable to Seller within five (5) Business Days of receipt of Seller’s invoice therefor. In addition, to the extent that interest is requested of Seller by Xxxxxxx regarding any withheld payments, Purchaser agrees that it shall pay interest on such withheld payment calculated from the original due date as provided in Section 13.5 within five (5) Business Days of receipt of Seller’s invoice therefor.

Section 18.3 Remedies for Default. Subject to the terms of Section 18.2, if an Event of Default occurs with respect to a defaulting Party at any time during the Term, the non-defaulting party may, for so long as the Event of Default is continuing, (i) establish a date consistent with Section 18.1 and Section 18.2 (which date shall be sixty (60) Days after the non-defaulting party delivers notice) (the “Early Termination Date”) on which this Agreement shall be canceled if the Event of Default has not been cured and send a written notice to the defaulting party stating the date of such Early Termination Date with the non-defaulting party’s invoice for the Break Up Fee (as defined below), (ii) withhold any payments due in respect of this Agreement and (iii) pursue any other remedies available at law or in equity except to the extent such remedies are limited or excluded by this Agreement. In addition to the remedies set forth in this Section 18.3, in connection with the cancellation of the Agreement on an Early Termination Date pursuant to this Section 18.3, the defaulting Party shall pay the non-defaulting party a break-up fee of Three Million Dollars ($3,000,000) (“Break Up Fee”) within five (5) Business Days of the defaulting party’s receipt of non-defaulting party’s invoice therefor.

Section 18.4 Seller’s One-Time Termination Right. During the period commencing on the date which is thirty (30) Days after the Effective Date and ending on the date one hundred eighty (180) Days after the Effective Date, Seller may terminate this Agreement upon written notice of such termination to Purchaser. Seller’s termination notice shall designate an Early Termination Date between ten (10) and fifteen (15) Days after

Purchaser’s receipt thereof. Purchaser shall calculate, in a commercially reasonable manner, a Settlement Amount for this Agreement as of the Early Termination Date. The Gains and Losses shall be determined by Purchaser by calculating the amount that would be incurred or realized by Purchaser to replace or to provide the economic equivalent of the remaining payments and/or deliveries in respect of the Agreement. Purchaser may determine its Gains and Losses by reference to information either available to it internally or supplied by one or more third parties including, without limitation, quotations (either firm or indicative) of relevant rates, prices, yields, yield curves, volatilities, spreads or other relevant market data in the relevant markets. Third parties supplying such information may include, without limitation, dealers in the relevant markets, end-users of the relevant product, information vendors and other sources of market information. Seller shall be entitled to review and evaluate a copy of all information utilized by Purchaser in calculating the Settlement Amount; provided, however, that all such information shall be deemed to be confidential and subject to the restrictions set forth in Section 21.11, provided, further, that this information shall be utilized by Seller solely in connection with Seller’s review and evaluation of, and any dispute regarding, the calculation of the Settlement Amount. In Purchaser’s calculation of the Settlement Amount, Purchaser shall be entitled to: (a) a termination option fee of Three Million Dollars ($3,000,000) and (b) any or all other amounts due to Purchaser under this Agreement. All of the amounts, payments or charges referenced in the preceding sentence shall be aggregated into a single liquidated amount (the “Termination Payment”) payable by Seller.

Notice of the Termination Payment shall be given by Purchaser to Seller of the amount of the Termination Payment. The notice shall include a written statement explaining in reasonable detail the calculation of such amount. The Termination Payment shall be made by the Party that owes it within two (2) Business Days after such notice is effective. If Seller disputes Purchaser’s calculation of the Termination Payment, in whole or in part, Seller shall, within two (2) Business Days of receipt of Purchaser’s calculation of the Termination Payment, provide to Purchaser a detailed written explanation of the basis for such dispute. Amounts paid as a result of any settlement or other resolution of the disputed amount shall be paid with interest thereon from the original due date as provided in Section 13.5.

Section 18.5 Purchaser’s Requirement Regarding the Assignment and Assumption Agreement. Purchaser agrees that it will use Commercially Reasonable Efforts to work diligently with Seller and/or Xxxxxxx to obtain the consent of Xxxxxxx and the Financing Parties to the assignment of the Xxxxxxx PPA pursuant to the Assignment and Assumption Agreement. Any failure by Purchaser to comply with the provisions of this Section 18.5 shall constitute an Event of Default pursuant to the terms of Section 18.1(b)(vi);provided however that this shall not be construed as an indication of whether any other section of this Agreement is or is not a material provision.

Section 18.6 Termination of Xxxxxxx PPA. If at any time during the Term of this Agreement the Xxxxxxx PPA is terminated for whatever reason, this Agreement shall be deemed to have been automatically terminated at the same time as the termination of the Xxxxxxx PPA without further action by either of the Parties. Seller and Purchaser agree to reasonably settle any outstanding matters under this Agreement with each other on a prompt basis in relation to the termination of this Agreement. Other than the payment of any costs and liabilities incurred prior to or upon the effective date of such termination, both Parties agree that neither Party shall have any liability to the other as a result of the termination of this Agreement pursuant to this Section 18.6. The provisions of this Section shall not affect any liability of a Party as a result of the occurrence of an Event of Default under this Agreement which liability shall be determined in accordance with Section 18.3 above.

ARTICLE XIX

Section 19.1 Indemnification.

Each Party shall indemnify and hold the other Party and its officers, directors, Affiliates, agents, employees, contractors and subcontractors, harmless from and against any and all Claims, to the extent caused by the negligence or willful misconduct of the indemnifying Party or the indemnifying Party’s own officers, directors, Affiliates, agents, employees, contractors or subcontractors and to the extent such Claims arise out of or relate to the indemnifying Party’s performance under this Agreement, in each case except to the extent such Claims are caused by

the negligence, willful misconduct, or breach of this Agreement by the indemnified Party or its officers, directors, Affiliates, agents, employees, contractors and subcontractors. In addition, each Party shall each indemnify, defend and hold harmless the other Party from any Claims, and whether or not such Claims result from the negligence or willful misconduct of the indemnifying Party or the indemnifying Party’s own officers, directors, Affiliates, agents, employees, contractors or subcontractors, arising from the Fuel or the Net Electrical Output that occur when risk of loss of the Fuel or Net Electrical Output is vested in the indemnifying Party, in each case except to the extent such Claims are caused by the negligence, willful misconduct, or breach of this Agreement by the indemnified Party or its officers, directors, Affiliates, agents, employees, contractors and subcontractors. The Parties agree that (a) the risk of loss with respect to such Claims related to Net Electric Output shall transfer from Seller to Purchaser at the Interconnection Points or the Replacement Power Delivery Points (as applicable) and (b) the risk of loss with respect to such Claims related to Fuel shall transfer from Purchaser to Seller at the Fuel Metering Points (as more fully described in Section 8.4). The indemnifying Party shall also reimburse the indemnified Party for any and all legal or other expenses (including attorneys’ fees) reasonably incurred by the indemnified Party in connection with Claims subject to this Section 19.1.

Section 19.2 Fines.

(a) Any fines, penalties or other costs incurred by either Party or such Party’s agents, employees or subcontractors for non-compliance by such Party, its agents, employees or subcontractors with the requirements of any Laws or Governmental Approvals shall not be reimbursed by the other Party but shall be the sole responsibility of such non-complying Party.

(b) If such fines, penalties or other costs are assessed against Purchaser by any Governmental Agency or court of competent jurisdiction due to the non-compliance by Xxxxxxx with any Laws or Governmental Approvals, Seller shall use Commercially Reasonable Efforts in accordance with its rights as purchaser under the Xxxxxxx PPA to recover from Xxxxxxx (a) any and all losses, liabilities, damages and claims suffered or incurred because of the failure of Xxxxxxx to comply therewith, and (b) any and all legal or other expenses (including attorneys’ fees) reasonably incurred by Purchaser in connection with such losses, liabilities, damages and claims. Seller shall promptly remit to Purchaser whatever it receives in connection therewith from Xxxxxxx.

(c) If such fines, penalties or other costs are assessed against Seller by any Governmental Agency or court of competent jurisdiction due to the non-compliance by Purchaser with any Laws or Governmental Approvals, Purchaser shall indemnify and hold harmless Seller against any and all losses, liabilities, damages and claims suffered or incurred because of the failure of Purchaser to comply therewith. Purchaser shall also reimburse Seller for any and all legal or other expenses (including attorneys’ fees) reasonably incurred by Seller in connection with such losses, liabilities, damages and claims.

Section 19.3 Limitations of Liability, Remedies and Damages.

(a) Each Party acknowledges and agrees that in no event shall any partner, shareholder, owner, officer, director, employee, or Affiliate of either Party be personally liable to the other Party for any payments, obligations, or performance due under this Agreement or any breach or failure of performance of either Party and the sole recourse for payment or performance of the obligations under this Agreement shall be against Seller or Purchaser and each of their respective assets and not against any other Person, except for such liability as expressly assumed by an assignee pursuant to an assignment of this Agreement in accordance with the terms hereof.

(b) This section has been intentionally deleted.

(c) Notwithstanding any provision of this Agreement to the contrary, after the Delivery Start Date of a Dedicated Unit, Seller shall have no obligation to deliver Replacement Power with respect to such Dedicated Unit to Purchaser, and Seller shall not be liable for any claims, damages or liabilities of any kind resulting from a Forced Outage or other failure to deliver Actual Contract Capacity or Net Electrical Output from such Dedicated Unit to Purchaser or for such Dedicated Unit to operate within the Design Limits (other than (i) as reflected in the calculation of Availability Adjustment Factor, (ii) Seller’s obligation to reimburse Purchaser for

Replacement Power requested by Seller to be provided pursuant to Sections 6.3, and Appendix E or, (iii) pursuant to Section 19.1, in which event this limitation of liability shall not apply); provided that the foregoing shall not limit the liability of Seller upon cancellation of this Agreement upon an Event of Default of Seller.

(d) THE PAYMENT, EXPRESS REMEDY OR MEASURE OF DAMAGES SET FORTH IN SECTIONS, 6.3, 8.3, 9.4, 10.1(b), 10.4, 12.1, 13.4, 13.5, 17.3, 18.3, 19.1, 19.2, AND THIS SECTION 19.3 SHALL BE THE SOLE AND EXCLUSIVE REMEDY WITH RESPECT TO SUCH SECTIONS. EACH PARTY’S LIABILITY SHALL BE LIMITED AS SET FORTH IN SUCH PROVISION AND ALL OTHER REMEDIES OR DAMAGES AT LAW OR IN EQUITY ARE WAIVED. UNLESS EXPRESSLY PROVIDED IN THIS AGREEMENT, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR CONSEQUENTIAL, INCIDENTAL, PUNITIVE, EXEMPLARY OR INDIRECT DAMAGES SUFFERED BY THAT PARTY OR BY ANY CUSTOMER OR ANY PURCHASER OF THAT PARTY, LOST PROFITS OR OTHER BUSINESS INTERRUPTION DAMAGES, BY STATUTE, IN TORT OR CONTRACT, UNDER ANY INDEMNITY PROVISION OR OTHERWISE; PROVIDED THAT THE FOREGOING SHALL NOT LIMIT DAMAGES FOR BREACH BY SELLER BASED ON THE INCREASE, IF ANY, IN PURCHASER’S COST OF OBTAINING REPLACEMENT POWER FROM ANOTHER SOURCE (WHETHER OR NOT SUCH REPLACEMENT POWER IS ACTUALLY PURCHASED BY PURCHASER) OVER THE AMOUNT WHICH WOULD BE PAYABLE BY PURCHASER UNDER THIS AGREEMENT WITH RESPECT TO SUCH POWER NOR LIMIT DAMAGES FOR BREACH BY PURCHASER BASED ON THE REDUCTION, IF ANY, IN PAYMENTS TO SELLER FROM THE SALE OF POWER FROM THE DEDICATED UNITS ARISING OUT OF SUCH BREACH. IT IS THE INTENT OF THE PARTIES THAT THE LIMITATIONS HEREIN IMPOSED ON REMEDIES AND THE MEASURE OF DAMAGES BE WITHOUT REGARD TO THE CAUSE OR CAUSES RELATED THERETO, INCLUDING, WITHOUT LIMITATION, THE NEGLIGENCE OF ANY PARTY, WHETHER SUCH NEGLIGENCE BE SOLE, JOINT OR CONCURRENT, OR ACTIVE OR PASSIVE. TO THE EXTENT ANY DAMAGES REQUIRED TO BE PAID HEREUNDER ARE LIQUIDATED, THE PARTIES ACKNOWLEDGE THAT THE DAMAGES ARE DIFFICULT OR IMPOSSIBLE TO DETERMINE, OTHERWISE OBTAINING AN ADEQUATE REMEDY IS INCONVENIENT AND THE LIQUIDATED DAMAGES CONSTITUTE A REASONABLE APPROXIMATION OF THE HARM OR LOSS. NOTWITHSTANDING ANY PROVISION IN THIS AGREEMENT TO THE CONTRARY, PURCHASER SHALL NOT BE LIABLE FOR ANY COSTS, CLAIMS OR DAMAGES WHICH ARE CALCULATED WITH RESPECT TO THE PERIOD OF TIME BEFORE OR AFTER THE TERM; UNDER NO CIRCUMSTANCES SHALL PURCHASER BE LIABLE FOR ANY COSTS, CLAIMS OR DAMAGES WHICH OCCUR DURING OR ARISE OUT OF A PERIOD OF TIME EITHER BEFORE OR AFTER THE TERM.

(e) The provisions of this Article XIX shall survive the termination of this Agreement.

ARTICLE XX

(b) If such designated representatives are unable to resolve a dispute under this Agreement, such dispute shall be referred by each Party’s representatives, respectively, to a senior officer designated by Seller and a senior officer designated by Purchaser for resolution upon five Days’ written notice from either Party.

(c) The Parties hereto agree (i) to attempt to resolve all disputes arising hereunder promptly, equitably and in a good faith manner; and (ii) to provide each other with reasonable access during normal business hours to any and all non-privileged records, information and data pertaining to any such dispute.

Section 20.2 Arbitration.

(a) In the event that any dispute between the Parties is unable to be resolved pursuant to Section 20.1 within 30 Days of the written notice described in Section 20.1(b), then either Party may commence a proceeding with respect to such dispute by written notice of arbitration specifying the matter to be arbitrated.

(b) Within twenty (20) Days of the notice given in Section 20.2 (a), the Parties shall select three (3) AAA approved commercial arbitrators, unless the Parties otherwise agree in writing to select the arbitrators from another source. To select these arbitrators, the Parties shall alternately strike names from a list of commercial arbitrators knowledgeable or experienced in the industry with no financial interest in any Party or any Affiliate of any Party obtained from the AAA or other agreed upon source, with the Party furnishing the Notice of Arbitration striking first, until three (3) Persons’ names remain on such list. Such Persons shall become the arbitrators of the matter. In the event any Person selected to be an arbitrator is unable or unwilling to serve, the process shall be repeated until three (3) arbitrators have been selected and have agreed to hear and resolve the dispute.

(c) The arbitrators shall permit each Party to conduct reasonable discovery as promptly and expeditiously as possible (and both Parties shall cooperate to this end). Discovery shall be limited to requests for the production of documents and examination upon deposition of witnesses designated as hearing witnesses. Each Party’s requests for, and responses to discovery including examination upon deposition shall be completed within sixty (60) Days of the arbitrators’ selection. The Parties may modify the period for discovery by mutual agreement. The arbitrators shall resolve any discovery disputes between the Parties that, after using their best efforts, the Parties cannot resolve themselves.

(d) The hearing shall be initiated as promptly and expeditiously as possible (and the Parties shall cooperate to this end) and, in no event more than thirty (30) Days after the conclusion of the discovery period. The rules of evidence of AAA shall apply to the presentation of evidence. Each Party shall file written direct testimony with the arbitrators and serve a copy on the other Party. Each Party shall be permitted to make opening statements with the Party demanding arbitration presenting its opening statement first. Immediately after opening statements, the Party demanding arbitration shall then present evidence in support of its position. The other Party then shall present evidence in support of its position. All witnesses must testify under oath, and a stenographic record and transcript of the hearing shall be made. Each Party shall have an opportunity to cross-examine the other Party’s witnesses. The Parties shall be permitted to make closing statements. The Party demanding arbitration shall present its statement first. The arbitrators shall conclude the hearing within thirty (30) calendar Days of its commencement. The period for concluding the hearing may be modified by mutual agreement of the Parties.

(e) The Parties shall submit proposed orders following the completion of the hearing unless otherwise agreed by the Parties and approved by the arbitrators. Pre-hearing briefs may be submitted and shall be served on other Parties. The pre-hearing briefs must be received by the arbitrators and the other Party no later than seven Business Days prior to commencement of the hearing. The briefing schedule provided herein may be modified by mutual agreement of the Parties with the approval of the arbitrators.

(f) The determination and/or award of the arbitrators, whichever is appropriate, shall be made no later than thirty (30) Days from the date of the completion of the hearing. Such determination and/or award shall be conclusive, final, and binding, subject only to the outcome of confirmation or vacation proceedings, if any, under applicable Law. To the extent that an award includes an amount of money, such award shall include interest at the Contract Interest Rate, and such interest shall accrue from the dates on which such money should have been paid to the prevailing Party or was incorrectly paid by that Party.

(g) Unless the Parties otherwise agree in writing, arbitration under this Agreement shall be conducted in Chicago, Illinois.

(h) Arbitration under this Agreement shall be governed by the AAA Commercial Arbitration Rules (or any successor thereto) in effect at the time of arbitration, unless the Parties mutually agree to another set of rules or body of Law, provided that if any specific provision of this Section conflicts with the then effective AAA Commercial Arbitration Rules, or other set of rules or body of Law mutually agreed to by the parties, then the provisions of this Section shall govern.

(i) The costs of the arbitration proceedings, other than the Parties’ own expenses, shall be shared equally by the Parties.

(j) The arbitrators shall have no power to amend or add to this Agreement, but shall have the authority to interpret the language of such Agreements and make findings of fact, order specific performance and provide injunctive relief as if the arbitrators were a court. Subject to such limitation, the decision of the arbitrators shall be final and binding. Judgment on an award may be enforced in any court of competent jurisdiction. Upon request of either Party, the arbitrators may issue such orders for interim relief as may be deemed necessary to safeguard the property that is the subject of arbitration or otherwise avoid irreparable harm to a Party, without prejudice to the rights of the Parties to the final determination of the dispute. Either Party may, without inconsistency with this Agreement, seek from any court of competent jurisdiction any interim or provisional relief that may be necessary to protect the rights or property of that Party, pending the establishment of the arbitration tribunal.

Section 21.11 Confidential Information.

(a) Prior to the dissemination of the initial public disclosure of this Agreement and the transactions contemplated therein, the Parties shall mutually agree upon the text of such disclosure.

(b) The terms contained in this Agreement are confidential information, and from and after the initial disclosure contemplated by paragraph (a) above, the Parties shall not disclose any such additional confidential information to any third party (other than the Party’s Affiliates or its lenders, counselors, accountants or rating agencies who have agreed to keep such terms confidential) without first obtaining the prior written consent of the non-disclosing Party. Notwithstanding the foregoing sentence, nothing herein shall prohibit either Party from making any public disclosure which it, with advice of counsel, deems reasonably necessary to comply with applicable Laws, including but not limited to securities laws or rules or regulations of a stock exchange or market on which the securities of the disclosing Party or any of its Affiliates are listed; provided that the disclosing Party provide the non-disclosing Party as much advance notice of such public disclosure as is practicable under the circumstances. Once the terms contained in this Agreement become generally available to the public as a result of the Parties’ actions in conformity with the provisions of this Sections 21.11 (a) and (b), the prohibitions on disclosure contemplated by this Section 21.11(b) shall have no further force and effect.

To the extent that such disclosures pursuant to clause (ii) of the preceding sentence are necessary, the Parties also agree that they shall endeavor in disclosing such information to seek to preserve the confidentiality of such disclosures. This provision shall not prevent either Party from providing any confidential information received from the other Party to any court in accordance with a proper discovery request or in response to the reasonable request of any Governmental Agency charged with regulating the disclosing Party’s affairs, provided that, if feasible, the disclosing Party shall give prior notice to the other Party of such disclosure and, if so requested by such other Party, shall have used all reasonable efforts to oppose or resist the requested disclosure, as appropriate under the circumstances, or to otherwise make such disclosure pursuant to a protective order or other similar arrangement for confidentiality.

(d) In addition to any other rights afforded by law or under this Agreement, the non-disclosing Party shall be entitled to injunctive relief in order to protect its rights under this Section 21.11.
