         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

         Agreement (as applicable) for Big Rivers' obligation to fund the

         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

         agrees that its respective share of the Capital Budget Limit for each
         Year shall be the amounts set forth below (collectively, the "Big

         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.

         paid the entire Big Rivers Contribution for a particular Year (or the
         required portion thereof, as contemplated in Section 20.6.2 above)

         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.

     of law rules of such jurisdiction" is hereby added to the end of the
     sentence.

- -    Section  22.2  (p.59).  The first and second  sentences  of Section 22.2
     are hereby  deleted and are replaced  with the  following  new  sentence:
     "LEM covenants and agrees, and Big Rivers  acknowledges and agrees,  that
     on the Closing Date and in the event the Marketing  Payment  contemplated
     in Section 4.3.9 exceeds $[REDACTED],  LEM will execute and deliver to the
     RUS a Demand  Promissory  Note in a principal  amount equal to the amount
     by which such  Marketing  Payment so exceeds $[REDACTED],  and in the form
     attached to this Agreement as Exhibit Q (the "Demand  Note")."  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."

                                                            EXECUTION ORIGINAL

     23 of the New Participation Agreement as follows:

         23.2 COLEMAN UNIT NO. 2 ISSUES. Big Rivers agrees that it will fully
         repair and rectify, at its expense and consistent with Prudent Utility
         Practice, all equipment and operating problems at the Coleman Unit No.
         2 facility identified in the letter dated May 14, 1998 from Michael
         Core to George Basinger, as well as all other problems (whether or not
         related) that may exist and that may prevent bringing that unit back on
         line for regular operation to its full rated capacity. 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. 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 any 
         failure of the Green landfill and/or the Wilson landfill to comply 
         with applicable Permits and/or conditions thereof at any time prior 
         to the Closing or completion of the construction work described 
         above, or the approval by the KNREPC of changes to the existing 
         Permits as described above, whichever is later, unless such failure 
         is caused by any action by any of the LG&E Parties or any of their 
         Affiliates, successors or assigns or their respective officers, 
         employees, consultants or agents.

         23.4 COLEMAN ASH POND ISSUES. 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. Big Rivers agrees that it shall be solely responsible, at
         its expense and as and when required by applicable Laws, for promptly
         taking all actions, and duly filing all instruments and documents with
         federal, state and local governmental agencies, as shall be required to
         officially close the "Southern Ash Pond" and the "Former Ash Pond" at
         the Coleman facility (as identified on the Coleman facility site map
         prepared in connection with the Baseline Environmental Audit Report) in
         accordance with all applicable Laws, Permits and Prudent Utility
         Practice. 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. Big Rivers hereby agrees to take all
         such actions, at its expense and consistent with Prudent Utility
         Practice, as shall be necessary in order to avoid any loss of
         transmission or other services in violation of its obligations under
         the Transmission Agreement or Big Rivers' Open Access Transmission
         Tariff by any of the LG&E Parties, the Members, the Smelters or Big
         Rivers over or in respect of

                                     -13-

                                                   Privileged and Confidential
                                                            EXECUTION ORIGINAL

         the passage of time from the year 1999 to the year 2000 (otherwise 
         known as the "millennium problem" or the "Year 2000 problem").

         23.7 M&S INVENTORY. Consistent with Section 9.1 of the New
         Participation Agreement, Big Rivers and Leaseco agree that, assuming
         the Parties agree upon the procedures to be set forth on Schedule 9.1
         to this Agreement as of the Closing (which agreement is a condition to
         the Closing), the fair market value to be paid by Leaseco at the
         Closing for all materials and supplies Inventory of Big Rivers shall be
         $[REDACTED].

         23.8 MAJOR CAPITAL REPAIRS. As an additional condition to the Parties'
         obligations to consummate the transactions contemplated at the Closing,
         the Parties shall have agreed upon a definition of "Major Capital
         Repairs" which generally shall include expenditures for Capital Assets
         which (i) are necessary to repair any turbine, scrubber or boiler at
         any of the Generating Plants, (ii) are not covered by insurance or any
         warranty, (iii) are not the result of the negligence or willful
         misconduct of any of the LG&E Parties or any of their Affiliates,

         consultants or agents or any breach or default by any of the LG&E
         Parties or their Affiliates under any of the Operative Documents and
         (iv) exceed a threshold amount to be agreed upon by the Parties.

         23.9 MISCELLANEOUS. Notwithstanding the provisions of Section 5.1.27 of
         this Agreement, the Parties acknowledge that the representations and
         warranties of Big Rivers set forth in Sections 23.2 through 23.9,
         inclusive, shall supplement the representations and warranties set
         forth in Article 5, and shall be in addition to and not in lieu of
         those representations and warranties.

    assigns," the word successor is hereby made plural.
- -   Section 24.5 (p.72). The reference to "Mortgagees" is hereby changed to

              6.5 BUDGET DEVIATIONS. WKEC shall immediately notify the Operating
         Committee of any anticipated departure of [REDACTED]% or more from an
         approved Annual Capital Budget or Annual O&M Budget. WKEC shall use
         reasonable efforts to (a) operate within [REDACTED] percent to 
         110 percent of the total approved Annual Capital Budget and 
         (b) spend at least [REDACTED] percent of the total approved Annual
         O&M Budget (not including the fuel or reagent budget). Subject to
         the provisions set forth below, any increase of [REDACTED]%
         or more proposed by WKEC to either budget shall be subject to review
         and approval by the Operating Committee (or in the case of the Annual
         Capital Budget, the Oversight Committee); provided, that such review
         and approval shall not apply to the Annual O&M Budgets that are
         included in the Initial Period Budgets, it being understood that
         increases of [REDACTED]% or more proposed by WKEC to those budgets 
         shall be permissible without that review and approval if the relevant
         expenditures are consistent with Prudent Utility Practice, in which
         case the additional costs will be borne by WKEC unless they constitute
         Incremental Environmental O&M required to be borne solely by Leaseco
         and Big Rivers in the manner provided for in Section 5 of the Cost
         Sharing Agreement. If WKEC exceeds the total budget for Non-Incremental
         Capital Costs (exclusive of such costs as are for Major Capital
         Repairs) that are included in an approved Annual Capital Budget, the
         additional cost of those Non-Incremental Capital Costs shall be borne
         by Leaseco unless the Parties otherwise agree, or unless remaining
         portions of the Big Rivers Contribution for that Year that were not
         included in the approved Annual Capital Budget are available as
         contemplated in Section 20.6.2 of the Participation Agreement (in which
         event such amounts will be applied as contemplated in that Section).
         Subject to the next succeeding sentence, if WKEC exceeds [REDACTED] 
         percent of the total budget for Incremental Capital Costs, or for Non-
         Incremental Capital Costs for Major Capital Repairs, in either case 
         that are included in an approved Annual Capital Budget, the additional
         costs of those Capital Assets shall be borne by Leaseco unless the 
         Parties otherwise agree, or unless the dispute resolution procedure 
         under Article 15 of the Participation Agreement determines that at the
         time WKEC proposed the applicable portions of the Annual Capital 
         Budget (or modification thereof) relating to those expenditures WKEC 
         acted consistent with Prudent Utility Practice, in which case the 
         additional costs shall be borne by Leaseco and Big Rivers in accordance
         with Sections 7.3 and 7.4 of the Cost Sharing Agreement. 
         Notwithstanding the provisions of the immediately preceding sentence,
         if WKEC exceeds [REDACTED] percent of the total of any budget for 
         Incremental Capital Costs, or for Non-Incremental Capital Costs for
         Major Capital Repairs, that are included in

         an approved Annual Capital Budget that is a part of the Initial 
         Period Budgets, the additional cost of those Capital Assets shall be 
         borne by Leaseco unless the Parties otherwise agree, or unless the 
         dispute resolution procedure under Article 15 of the Participation 
         Agreement determines that the purchase and installation of those 
         Capital Assets, and the costs thereof, are consistent with Prudent 
         Utility Practice, regardless of whether the relevant Initial Period 
         Budget, or WKEC's or Leaseco's (as applicable) actions in connection 
         with the same, were consistent with Prudent Utility Practice at the 
         time that budget was prepared, in which case the additional costs 
         shall be borne by Leaseco and Big Rivers in accordance with Sections 
         7.3 and 7.4 of the Cost Sharing Agreement. If WKEC fails or refuses 
         to use reasonable efforts to spend at least [REDACTED] percent of the
         total approved Annual Capital Budget or the total approved Annual O&M
         Budget (excluding that portion relating to Incremental Environmental 
         O&M) and pursuant to the dispute resolution procedure under Article 
         15 of the Participation Agreement it is determined that such failure 
         or refusal is inconsistent with Prudent Utility Practice, WKEC shall 
         make the omitted expenditure as required pursuant to the applicable 
         dispute resolution procedure.

         Operating Emergency which are not already included in an approved
         Annual Capital Budget shall be paid for by Leaseco unless (a) the same
         represents an Incremental Capital Cost or expenditures for a Major
         Capital Repair, in which case such expenditures shall be paid by
         Leaseco and Big Rivers in accordance with Article 7 of the Cost Sharing
         Agreement, or (b) Big Rivers shall not have paid the entire Big Rivers
         Contribution for that Year toward funding of one or more
         Non-Incremental Capital Costs (other than costs for Major Capital
         Repairs) and/or Henderson Non-Incremental Capital Costs (other than
         costs for Henderson Major Capital Costs) 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 that
         remaining amount will be allocated to any Non-Incremental Capital Costs
         in that Year resulting from that Operating Emergency as contemplated in
         Section 20.6.2 of the Participation Agreement.

         Operating Committee of any anticipated departure of [REDACTED]% or more
         from an approved Annual Capital Budget or Annual O&M Budget. Leaseco 
         shall use reasonable efforts to (a) operate within [REDACTED] percent
         to [REDACTED] percent of the total approved Annual Capital Budget and
         (b) spend at least [REDACTED] percent of the total approved Annual 
         O&M Budget (not including the fuel and reagent budget). Subject to
         the provisions set forth below, any increase of [REDACTED]% or more
         proposed by Leaseco to either budget shall be subject to review and
         approval by the Operating Committee; provided, that such review and
         approval shall not apply to the Annual O&M Budgets that are included
         in the Initial Period Budgets, it being understood that increases of
         [REDACTED]% or more proposed by Leaseco to those budgets shall be
         permissible without that review and approval if the relevant
         expenditures are consistent with Prudent Utility Practice, in which
         case the additional costs will be borne by Leaseco unless they
         constitute Incremental Environmental O&M required to be borne solely by
         Leaseco and Big Rivers in the manner provided for in Section 2.3.3. If
         Leaseco exceeds the total budget for Non-Incremental Capital Costs
         (exclusive of such costs as are for Major Capital Repairs) that are

                                     -18-



         included in an approved Annual Capital Budget, the additional cost of
         those Non-Incremental Capital Costs shall be borne by Leaseco unless
         the Parties otherwise agree, or unless remaining portions of the Big
         Rivers Contribution for that Year that were not included in the
         approved Annual Capital Budget are available as contemplated in Section
         20.6.2 of the Participation Agreement (in which event such amounts will
         be applied as contemplated in that Section). Subject to the next
         succeeding sentence, if Leaseco exceeds [REDACTED] percent of the total
         budget for Incremental Capital Costs, or for Non-Incremental Capital
         Costs for Major Capital Repairs, in either case that are included in an
         approved Annual Capital Budget, the additional costs of those Capital
         Assets shall be borne by Leaseco unless the Parties otherwise agree, or
         unless the dispute resolution procedure under Article 15 of the 
         Participation Agreement determines that at the time Leaseco proposed 
         the applicable portions of the Annual Capital Budget (or modification 
         thereof) relating to those expenditures Leaseco acted consistent with 
         Prudent Utility Practice, in which case the additional costs shall be 
         borne by Leaseco and Big Rivers in accordance with Sections 8.3 and 
         8.4. Notwithstanding the provisions of the immediately preceding 
         sentence, if Leaseco exceeds [REDACTED] percent of the total of any 
         budget for Incremental Capital Costs, or for Non-Incremental Capital
         Costs for Major Capital Repairs, that are included in an approved 
         Annual Capital Budget that is a part of the Initial Period Budgets,
         the additional cost of those Capital Assets shall be borne by Leaseco
         unless the Parties otherwise agree, or unless the dispute resolution
         procedure under Article 15 of the Participation Agreement determines 
         that the purchase and installation of those Capital Assets, and the 
         costs thereof, are consistent with Prudent Utility Practice, regardless
         of whether the relevant Initial Period Budget, or Leaseco's actions in
         connection with the same, were consistent with Prudent Utility Practice
         at the time that budget was prepared, in which case the additional
         costs shall be borne by Leaseco and Big Rivers in accordance with
         Sections 8.3 and 8.4. If Leaseco fails or refuses to use reasonable
         efforts to spend at least [REDACTED] percent of the total approved 
         Annual Capital Budget or the total approved Annual O&M Budget 
         (excluding that portion relating to Incremental Environmental O&M) and
         pursuant to the dispute resolution procedure under Article 15 of the
         Participation Agreement it is determined that such failure or refusal
         is inconsistent with Prudent Utility Practice, Leaseco shall make the
         omitted expenditure as required pursuant to the applicable dispute 
         resolution procedure.

              7.6 OPERATING EMERGENCY. Notwithstanding any other provision of
         this Agreement, in the event of an Operating Emergency, Leaseco 

                                     -19-

         maintain the safety, integrity and operability of the Tangible 
         Assets and to maintain Capacity and the availability of the Tangible 
         Assets to the maximum extent. Additional capital expenditures 
         incurred by Leaseco in response to an Operating Emergency which are 
         not already included in an approved Annual Capital Budget shall be 
         paid for by Leaseco unless (a) the same represents an Incremental 
         Capital Cost or expenditures for a Major Capital Repair, in which 
         case such expenditures shall be paid by Leaseco and Big Rivers in 
         accordance with Article 8 of this Agreement, or (b) Big Rivers shall 
         not have paid the entire Big Rivers Contribution for that year 
         toward funding of one or more Non-Incremental Capital Costs (other 
         than costs for Major Capital Repairs) and/or Henderson

         Capital Costs) 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 that remaining amount 
         will be allocated to any Non-Incremental Capital Costs resulting

         the Participation Agreement.

         budget for Station Two Improvements or for operating and maintenance
         expenses included in any approved Operating Budget. Station Two

         [REDACTED] percent to [REDACTED] percent of the total approved budget
         for Station Two Improvements included in an Operating Budget, and 
         (b) to spend at least [REDACTED] percent of the total approved budget

         reagent budget). Subject to the provisions set forth below, any 
         increase of [REDACTED] percent or more proposed by Station Two
         Subsidiary to either the Station Two Improvements budget or the 
         operating and maintenance expense budget set forth in an approved
         Operating Budget shall be subject to review and approval by the 
         Operating Committee; provided, that such review and approval shall
         not apply to the operating and maintenance expense budgets that are
         included in an Operating Budget that is a part of the Initial Period
         Budgets, it being understood that increases of [REDACTED] percent or
         more proposed by Station Two Subsidiary to those budgets shall be 
         permissible without that review and approval if the relevant 
         expenditures are consistent with Prudent Utility Practice, in which
         case the additional costs that are allocable to Big Rivers under 
         the Station Two Contracts shall, as between Big Rivers and Station
         Two Subsidiary, be borne by Station Two Subsidiary unless they 
         constitute Henderson Incremental Environmental O&M required to be
         borne by both Station Two Subsidiary and Big Rivers in the manner
         provided for in Section 8.16. If Station Two Subsidiary exceeds 
         the total budget for Henderson Non-Incremental Capital Costs 
         (exclusive of such costs as are for Henderson Major Capital Repairs)
         that are included in an approved budget for Station Two Improvements
         in an Operating Budget, the additional cost of those Henderson Non-
         Incremental Capital Costs that are allocable to Big Rivers under 
         the Station Two Contracts shall, as between Big Rivers and Station
         Two Subsidiary, be borne by Station Two Subsidiary unless the 
         parties agree otherwise, or unless remaining portions of the Big 
         Rivers Contribution for that Year that were not included in the 
         approved Operating Budget are available as contemplated in
         Section 20.6.2 of the Participation Agreement (in which event such
         amounts will be applied as contemplated in that Section). Subject
         to the next succeeding sentence, if Station Two Subsidiary exceeds
         [REDACTED] percent of the total approved budget for Henderson 
         Incremental Capital Costs, or for Henderson Non-Incremental Capital
         Costs for Major Capital Repairs, in either case that are included
         in an approved Operating Budget, the additional costs of those 
         Station Two Improvements that are allocable to Big Rivers under the
         Station Two Contracts shall, as between Big Rivers and Station Two
         Subsidiary, be borne by Station Two Subsidiary unless the Parties
         otherwise agree, or unless the dispute resolution procedure under
         Article 15 of the Participation Agreement (and contemplated in 
         Section 13.5(e) of this Agreement) determines that at the time 
         Station Two Subsidiary proposed the applicable portions of the 
         Operating Budget (or modification thereof) relating to those 
         expenditures Station Two Subsidiary acted consistent with Prudent
         Utility Practice, in which case the additional costs shall be borne
         by Station Two Subsidiary and Big Rivers in accordance with 
         Sections 8.17(d) and 8.17(e) of this Agreement. Notwithstanding
         the provisions

         of the immediately preceding sentence, if Station Two Subsidiary 
         exceeds [REDACTED] percent of the total of any approved budget for 
         Henderson Incremental Capital Costs, or for Henderson 
         Non-Incremental Capital Costs for Major Capital Repairs, that are 
         included in an Operating Budget that is a part of the Initial Period 
         Budgets, the additional cost of those Station Two Improvements that 
         are allocable to Big Rivers under the Station Two Contracts shall, 
         as between Big Rivers and Station Two Subsidiary, be borne by 
         Station Two Subsidiary unless the Parties otherwise agree, or unless 
         the dispute resolution procedure set forth in Article 15 of the 
         Participation Agreement determines that the purchase and 
         installation of those Station Two Improvements, and the costs 
         thereof, are consistent with Prudent Utility Practice, regardless of 
         whether the relevant Initial Period Budget, or Station Two 
         Subsidiary's actions in connection with the same, were consistent 
         with Prudent Utility Practice at the time that the budget was 
         prepared, in which case the additional costs that are allocable to 
         Big Rivers under the Station Two Contracts shall, as between Big 
         Rivers and Station Two Subsidiary, be borne by Station Two 
         Subsidiary and Big Rivers in accordance with Sections 8.17(d) and 
         8.17(e) of this Agreement. If Station Two Subsidiary fails or 
         refuses to use reasonable efforts to spend at least [REDACTED] percent
         of the total budget for Station Two Improvements or for operating and 
         maintenance expenses included in an approved Operating Budget 
         (excluding that portion relating to Henderson Incremental 
         Environment O&M), and pursuant to the dispute resolution procedure 
         under Article 15 of the Participation Agreement it is determined 
         that such failure or refusal was inconsistent with Prudent Utility

         Subsidiary's actions in connection with the same, were consistent
