The applicable provisions contained in the Phase I or Phase II Agreements, as applicable, shall replace this provision on and after the Effective Date. -3- Privileged and Confidential EXECUTION ORIGINAL 20.6.2. Notwithstanding Section 20.6.1, above, the Parties hereby agree that the Annual Capital Budgets for the Initial Budget Period to be agreed to by the Parties as contemplated in Schedule 3.1 attached to this Agreement, and the Annual Capital Budgets for each Year thereafter during the Term, shall include as the aggregate budgeted amount for the relevant Year (or portion thereof), in respect of all Non-Incremental Capital Costs and Henderson Non-Incremental Capital Costs (as defined in the Station Two Agreement) that are not for Major Capital Repairs or Henderson Major Capital Repairs, respectively, the following amounts (the "Capital Budget Limits"), which Capital Budget Limits shall not be increased or decreased without the written approval of the Parties, but shall be subject to adjustment pursuant to the procedures to be developed by Big Rivers and Leaseco as contemplated in Section 20.6.4 below, and shall be subject to the other provisions of this Section 20.6: - - First Partial Year following Effective Date (assuming there are five full months then remaining in that Year): $ - - First full Year following Effective Date: $ - - Second full Year following Effective Date: $ - - Third full Year following Effective Date: $ - - Fourth full Year following Effective Date: $ - - Fifth full Year following Effective Date: $ - - Sixth full Year following Effective Date: $ - - Seventh full Year following Effective Date: $ - - Eighth full Year following Effective Date: $ - - Ninth full Year following Effective Date: $ - - Tenth full Year following Effective Date: $ - - Eleventh full Year following Effective Date: $[REDACTED] - - Twelfth full Year following Effective Date: $ - - Thirteenth full Year following Effective Date: $ - - Fourteenth full Year following Effective Date: $ - - Fifteenth full Year following Effective Date: $ - - Sixteenth full Year following Effective Date: $ - - Seventeenth full Year following Effective Date: $ - - Eighteenth full Year following Effective Date: $ - - Nineteenth full Year following Effective Date: $ - - Twentieth full Year following Effective Date: $ - - Twenty-First full Year following Effective Date: $ - - Twenty-Second full Year following Effective Date: $ - - Twenty-Third full Year following Effective Date: $ - - Twenty-Fourth full Year following Effective Date: $ - - Twenty-Fifth full Year following Effective Date: $ -4- Privileged and Confidential EXECUTION ORIGINAL Except as otherwise provided below, Big Rivers, Leaseco and/or Station Two Subsidiary each agree to contribute their respective share of the Capital Budget Limit for each Year (or portion thereof) during the Term, based upon their respective Capital Asset Sharing Ratios or Station Two Improvement Sharing Ratios (as defined in the Station Two Agreement), as applicable; provided, that so long as the aggregate budgeted amount for Non-Incremental Capital Costs and Henderson Non-Incremental Capital Costs that are included in the approved Annual Capital Budget and Operating Budget (in the case of Station Two) for a particular Year, but which are not for Major Capital Repairs or Henderson Major Capital Repairs, respectively (the "Approved Capital Amount"), is equal to or greater than the Big Rivers Contribution for that Year, then Big Rivers will contribute the entire Big Rivers Contribution (as defined in Section 20.6.3 below) for that Year and Leaseco and/or Station Two Subsidiary will contribute the remainder of the Approved Capital Amount; and provided further, that in the event the Approved Capital Amount for a particular Year is less than the Big Rivers Contribution for that Year, then Big Rivers alone shall contribute the entire Approved Capital Amount. Notwithstanding anything contained in this Section 20.6 to the contrary Leaseco and/or Station Two Subsidiary shall be entitled to propose an aggregate annual budget for Non-Incremental Capital Costs (exclusive of costs for Major Capital Repairs) and Henderson Non-Incremental Capital Costs (exclusive of Costs for Henderson Major Capital Repairs) that is less than the Capital Budget Limits for that Year, provided such budget is consistent with Prudent Utility Practice, and such budget as proposed by Leaseco and/or Station Two Subsidiary shall be approved if it meets the criteria for such approval in Article 6 of the Cost Sharing Agreement, Article 7 of the Lease and Section 8.15 or 9.8 of the Station Two Agreement (as applicable) notwithstanding that it may be less than the Capital Budget Limit. In addition to the foregoing, in the event the Approved Capital Amount for a particular Year is less in the aggregate than the Big Rivers Contribution for that Year, Big Rivers agrees to contribute the amount by which the Big Rivers Contribution exceeds the Approved Capital Amount, to fund any Non-Incremental Capital Costs and Henderson Non-Incremental Capital Costs (in each case exclusive of costs for Major Capital Repairs and Henderson Major Capital Repairs) that were not included in the relevant approved budget, but which (i) are required during that Year, consistent with Prudent Utility Practice, to be expended in order to address unanticipated operating problems at one or -5- Privileged and Confidential EXECUTION ORIGINAL more of the Generating Plants, and (ii) meet the criteria and conditions set forth in Article 7 of the Cost Sharing Agreement, Article 8 of the Lease or Section 8.17 or 9.10 of the Station Two Agreement (as applicable) for Big Rivers' obligation to fund the same. Such contributions by Big Rivers will serve as an approved deviation from the Annual Capital Budget for that Year as contemplated in Section 6.5 of the Facilities Operating Agreement, Section 7.5 of the Lease or Section 8.17(f) or 9.10(d) of the Station Two Agreement, as applicable. 20.6.3 Except as otherwise provided in this Section 20.6, Big Rivers agrees that its respective share of the Capital Budget Limit for each Year shall be the amounts set forth below (collectively, the "Big Rivers Contributions"), which amounts shall be paid by Big Rivers at the time(s) provided in Article 7 of the Cost Sharing Agreement, Article 8 of the Lease and Section 8.17 or 9.10 of the Station Two Agreement, as applicable: - - First Partial Year: $ - - First full Year: $ - - Second full Year: $ - - Third full Year: $ - - Fourth full Year: $ - - Fifth full Year: $ - - Sixth full Year: $ - - Seventh full Year: $ - - Eighth full Year: $ - - Ninth full Year: $ - - Tenth full Year: $ - - Eleventh full Year: $[REDACTED] - - Twelfth full Year: $ - - Thirteenth full Year: $ - - Fourteenth full Year: $ - - Fifteenth full Year: $ - - Sixteenth full Year: $ - - Seventeenth full Year: $ - - Eighteenth full Year: $ - - Nineteenth full Year: $ - - Twentieth full Year: $ - - Twenty-First full Year: $ - - Twenty-Second full Year: $ - - Twenty-Third full Year: $ - - Twenty-Fourth full Year: $ - - Twenty-Fifth full Year: $ -6- Privileged and Confidential EXECUTION ORIGINAL Big Rivers agrees that the amount of the Big Rivers Contribution for a particular Year shall not be reduced in the event the Approved Capital Amount is less than the Capital Budget Limit for the year, so long as the Approved Capital Amount is equal to or greater than the Big Rivers Contribution. 20.6.4 The Parties agree that, as an additional condition to the Closing and the Parties' obligation to consummate the transactions contemplated at the Closing, Big Rivers and Leaseco must agree upon a mutually satisfactory procedure by which the Capital Budget Limits and the Big Rivers Contributions will be adjusted during the Term to reflect inflationary increases in the cost of Non-Incremental Capital Costs over that period. The Parties agree to negotiate in good faith to develop and agree upon that procedure at the earliest practicable time following the Execution Date, and shall document their agreement (if any) in writing at or prior to the Closing. 20.6.5 Notwithstanding anything contained in any Operative Document to the contrary, but subject to the limitations and conditions set forth in this Section 20.6, at such time as Big Rivers shall have paid the entire Big Rivers Contribution for a particular Year (or the required portion thereof, as contemplated in Section 20.6.2 above) toward the funding of one or more Non-Incremental Capital Costs (other than for Major Capital Repairs) and/or Henderson Non-Incremental Capital Costs (other than for Henderson Major Capital Repairs), in either case in accordance with Article 7 of the Cost Sharing Agreement, Article 8 of the Lease and/or Section 8.17 or 9.10 of the Station Two Agreement (as applicable), then (a) Big Rivers shall be deemed to have paid its entire share of all Non-Incremental Capital Costs (other than for Major Capital Repairs) and Henderson -7- Non-Incremental Capital Costs (other than for Henderson Major Capital Repairs) for that Year (or portion thereof), regardless of whether additional expenditures for those or other Non-Incremental Capital Costs (other than for Major Capital Repairs) or Henderson Non-Incremental Capital Costs (other than for Henderson Major Capital Repairs) have been budgeted for, or are thereafter required during that Year for the maintenance and upkeep of the Generating Plants in accordance with the Operative Documents, and (b) Leaseco or Station Two Subsidiary, as applicable, agree that they shall be responsible for the payment of all other Non-Incremental Capital Costs (exclusive of costs for Major Capital Repairs) and Henderson Non-Incremental Capital Costs (exclusive of costs for Henderson Major Capital Repairs) during that Year to maintain and operate the Facilities and Station Two in accordance with the Operative Documents notwithstanding the Capital Budget Limit for that Year (or portion thereof). Notwithstanding the immediately preceding sentence or any other provision in any Operative Document to the contrary, Big Rivers' payment of the Big Rivers Contribution for a particular Year as contemplated above shall not, and shall not be deemed to, affect, limit or eliminate Big Rivers' continuing obligation under Article 7 of the Cost Sharing Agreement, Article 8 of the Lease or Section 8.17 or 9.10 (as applicable) of the Station Two Agreement for the payment of Big Rivers' relevant Capital Asset Sharing Ratio or Station Two Improvement Sharing Ratio with respect to (a) any Incremental Capital Costs or Henderson Incremental Capital Costs, and (b) any Non-Incremental Capital Costs for Major Capital Repairs or Henderson Non-Incremental Capital Costs for Henderson Major Capital Repairs, in each case that are required to be funded by Big Rivers, directly or indirectly, in accordance with those Articles or Sections, it being expressly understood that all such obligations of Big Rivers shall continue in accordance with those provisions irrespective of the provisions of this Section 20.6, and, where reasonably possible, shall be separately budgeted for by the Parties in the Annual Capital Budgets or Operating Budgets (in the case of Station Two) in accordance with the Cost Sharing Agreement, the Facilities Operating Agreement, the Lease or the Station Two Agreement, as applicable. In addition to the foregoing, and except as otherwise provided in this Section 20.6, nothing in this Section 20.6 shall be deemed to affect, limit or eliminate Big Rivers' or the LG&E Parties' respective obligations or liabilities under or pursuant to this or any other Operative Document by reason of any misrepresentation, breach of warranty or non-fulfillment of any covenant or agreement of Big Rivers or such LG&E Parties, including without limitation, any indemnification and hold harmless covenant of Big Rivers or such LG&E Parties set forth herein or therein. 20.6.6 To the extent any portion of a Big Rivers Contribution that is included in an approved Annual Capital Budget or Operating Budget (in the case of Station Two) is not thereafter used by Leaseco or Station Two Subsidiary in the Year for which payable because the project for which such funds were allocated was deferred or was not completed during that Year, after complying with the provisions of the Operative Documents, then such portion of the Big Rivers Contribution necessary to complete such project will be carried forward and included as an approved addition to the Annual Capital Budget or Operating Budget (as applicable) for the following Year (for use solely in -8- connection with the completion of such project), but shall not serve as a credit against, or reduce, the Big Rivers Contribution for that following Year; provided, that the obligation of Big Rivers to so contribute any such portion of the Big Rivers Contribution in that following Year shall be further conditioned on either (i) Leaseco or Station Two Subsidiary having actually contributed, during the Year for which budgeted, its commitment for Non-Incremental Capital Costs or Henderson Non-Incremental Capital Costs that corresponds with such portion of the Big Rivers Contribution (based upon Leaseco's Capital Asset Sharing Ratio or Station Two Subsidiary's Station Two Improvement Sharing Ratio, as applicable), or (ii) Leaseco's or Station Two Subsidiary's agreement with Big Rivers to make those corresponding contributions at the same time in the following Year as such contributions are required by Big Rivers. References in this Section 20.6 to the Operating Budgets required for Station Two shall be deemed to relate solely to the items and amounts set forth in those budgets for which Big Rivers and/or Station Two Subsidiary are responsible under the Station Two Agreement and the Station Two Contracts referenced therein. 20.6.7 Notwithstanding anything contained in this Agreement or in any other Operative Document to the contrary, the Parties agree that they shall not, at any time after the sixtieth (60th) day following the close of any Year, attempt to claim or assert any claim (A) that an expenditure incurred in that Year and included in the approved Annual O&M Budget, the approved Annual Capital Budget or the approved Operating Budget (in the case of Station Two) for that Year (including without limitation, items that were included in those budgets by agreement of the Parties, by decision of the Operating Committee or Oversight Committee (as applicable), or at the direction of an arbitration panel pursuant to the procedures set forth in Article 15) should in fact have been included in the other budget for that Year, (B) that an expenditure incurred in that Year and included as an expenditure for a Capital Asset or Station Two Improvement in any of those approved budgets is in fact an operation or maintenance expense or an Enhancement or Major Capital Improvement, or is a Capital Asset or Station Two Improvement that Big Rivers is not otherwise obligated to fund in part, (C) that an expenditure incurred in that Year and included as an operation or maintenance expense in any of those approved budgets is in fact an expenditure for a Capital Asset or Station Two Improvement that Big Rivers is obligated to fund in part, (D) that an expenditure incurred in that Year and included in those approved budgets is or is not for a Major Capital Repair or a Henderson Major Capital Repair, (E) that an expenditure incurred in that Year and -9- included as Incremental Environmental O&M in any of those approved budgets is not in fact Incremental Environmental O&M, or (F) that an expenditure incurred in that Year and included as an operation and maintenance expense that is not Incremental Environmental O&M is in fact Incremental Environmental O&M; provided, however that nothing contained in this Section 20.6.7 shall be deemed to affect, limit or eliminate any such claims that are specifically asserted with respect to one or more items included in those approved budgets at any time prior to the expiration of the foregoing sixty-day period following the close of any Year, any such claims that are asserted prior to the approval of such budgets (or deemed approval pursuant to an arbitration award as contemplated above), or any claims regarding expenditures the approval or characterization of which was obtained by a Party through any misrepresentation or fraudulent or other willful misconduct, all of which claims shall be deemed to survive that sixty-day period for all purposes. - - Section 21.4 (p.54).

Exhibit Q attached to this Amendment shall constitute Exhibit Q of the New Participation Agreement as contemplated above. The fifth sentence of Section 22.2 is hereby amended to be and read in its entirety as follows: "Notwithstanding the foregoing, so long as any amount remains outstanding under either of the two Promissory Notes to be issued by Big Rivers to the RUS pursuant to the New RUS Agreement (as defined in the Non-Disturbance Agreement) or under the "1983 Reimbursement Agreement", the "1985 Reimbursement Agreement" or the "AMBAC Notes" (each with AMBAC as referred to in Recital A of the Non-Disturbance Agreement), or under Big Rivers' pollution control bonds as outstanding on the Effective Date, Big Rivers agrees that it shall not, and LEM agrees that Big Rivers shall have no obligation to, pay any amount with respect to Big Rivers' Reimbursement Obligation(s), provided however, that interest at the Default Rate will continue to accrue during all such periods during which Big Rivers has no payment obligation." A new sentence is hereby added to the end of Section 22.2 of the New Participation Agreement as follows: "Big Rivers' Reimbursement Obligation(s), together with its obligation to pay interest accruing on such reimbursement amounts, shall survive any expiration or termination of this Agreement and shall continue to be binding on Big Rivers." - - New Sections (p.60).

Big Rivers will use its commercially reasonable efforts to address those problems at the earliest practicable time, in an effort to return the Coleman Unit No. 2 facility on-line prior to July 14, 1998 (or as soon thereafter as is reasonably possible). The foregoing obligations of Big Rivers will survive the Closing and shall continue to be binding on Big Rivers. Notwithstanding the foregoing, Big Rivers acknowledges and agrees that the LG&E Parties shall be under no obligation to effect the Closing or to consummate the transactions contemplated at the Closing until such time as the Coleman Unit 2 facility is repaired in accordance with the preceding provisions. 23.3 GREEN AND WILSON LANDFILL ISSUES. Big Rivers hereby represents and warrants to the LG&E Parties that the landfill located at the Green Station has a remaining useful life and capacity, based upon coal qualities that are consistent with Big Rivers' prior practices, of at least nine (9) years, without modification of any of the existing Permits relative to that landfill, without the need for capital improvements or the disruption or removal of materials located in that landfill, and based upon both vertical and horizontal measurement limitations, but assuming the continuation of Big Rivers' past operation and disposal practices by WKEC or Leaseco, as applicable, following the Effective Date. Big Rivers agrees that prior to the Closing (or as soon thereafter as is reasonably possible, using its commercially reasonable efforts) Big Rivers will, at its expense and consistent with Prudent Utility Practice, construct a new retainment road/wall at the Green Station landfill as contemplated by the pending Permit modification filed with the KNREPC and in compliance with all applicable Laws and Permits. Big Rivers further agrees, at its expense and at the earliest practicable time, to obtain all changes in existing Permits required for the full and lawful use and operation of the Green landfill (as expanded) and the Wilson landfill by the LG&E Parties following the Closing. In the event changes in existing Permits that would allow Big Rivers to forego such removal action in compliance with applicable Laws cannot be obtained despite Big Rivers' commercially reasonable efforts to do so, Big Rivers -11- Privileged and Confidential EXECUTION ORIGINAL agrees, at its expense and consistent with Prudent Utility Practice, to ensure that any landfill materials that have been placed or disposed of outside the permitted boundaries of the Green landfill and the Wilson landfill are removed along with any affected soil or debris, and disposed of in compliance with applicable Laws at the earliest possible time.

The LG&E Parties agree that, except as otherwise required by applicable Laws, the LG&E Parties shall not attempt to unilaterally close the "Southern Ash Pond" or the "Former Ash Pond" at the Coleman facility without the prior written consent of Big Rivers.

Notwithstanding the foregoing, in the event the LG&E Parties elect, in their discretion, to dispose of materials in the Southern Ash Pond or the Former Ash Pond, WKEC or Leaseco, as applicable, shall be responsible for a pro rata portion of those closure costs based on the total amount (in tons) of ash disposed of in those ash ponds by the LG&E Parties as compared with the total amount of ash in the ponds at their closure. In addition to the foregoing, Big Rivers agrees, at its expense, to promptly commence and continue to dredge and excavate the remaining active ash pond (the "Active Ash Pond") at the Coleman facility in such a manner as shall be sufficient to cause the remaining useful life and capacity of that ash pond (based on horizontal and vertical measurements) as of one (1) month following the Closing to be at least -12- Privileged and Confidential EXECUTION ORIGINAL thirteen (13) months under its existing Permits, assuming a continuation of the current capacity factor of the Coleman facility, and assuming no additional dredging or excavation of that ash pond during that 13-month period. All materials so dredged from the Coleman ash pond shall be disposed of by Big Rivers, at its expense, at a permitted landfill or other permitted site located outside the boundaries of any of the Generating Plants or related facilities other than the Coleman Station, and otherwise in compliance with all applicable Laws. Big Rivers also agrees to be solely responsible for, and to indemnify and hold harmless the LG&E Parties from and against, all claims, demands, losses, damages, liabilities, costs, expenses, obligations, and deficiencies (including without limitation, costs of corrective or remedial actions, fines, civil or criminal penalties, settlements and attorney's fees) that have been or may be suffered or incurred resulting from or arising out of (a) any failure of the Active Ash Pond to comply with all applicable Permits at any time prior to the Closing or the completion of the dredging and excavation work described above, whichever is later, (b) any use or disturbance of the "Southern Ash Pond" or the "Former Ash Pond" by Big Rivers at any time prior to the Closing, or any failure of those ash ponds to comply with all applicable Permits at any time prior to the closure of the same as contemplated above (except to the extent that such non-compliance is caused by the use of or the failure to permit (assuming they are otherwise permittable) those ash ponds by the LG&E Parties following the Closing), and (c) any delay in the closure of the "Southern Ash Pond" or the "Former Ash Pond" at the Coleman facility (except to the extent that such delay is caused by the LG&E Parties or any of their Affiliates, successors or assigns or their respective officers, employees, consultants or agents). 23.5 COLEMAN OPACITY ISSUE. Big Rivers hereby represents and warrants to the LG&E Parties that Big Rivers has taken all such actions, and has made all such repairs (at its expense and consistent with Prudent Utility Practice), in respect of the Coleman facility as were necessary to eliminate the opacity issues or problems identified in the letter from Big Rivers to the KNREPC dated February 11, 1998, relating to opacity exceedances at that facility. 23.6 YEAR 2000 COMPLIANCE ISSUE.
