GPC, on its own behalf and as agent for the other Common Coal Stockpile Participants and for the Separate Coal Stockpile Participants which are then Common Procurement Participants electing to participate in such Common Procurement, shall then initiate a Common Procurement in an effort to obtain offers from coal vendors to sell coal, offers from transporters to provide transportation, or both (individually, an "Offer" and collectively, "Offers") to meet the requirements and procurement strategy of GPC for the Common Coal Stockpile and of each of the Separate Coal Stockpile Participants which are Common Procurement Participants electing to participate in such Common Procurement for its Separate Coal Stockpile. (B) Coal and Transportation Procurement by GPC - After Receipt of Offers. Upon receipt of one or more Offers, GPC, on its own behalf and as agent for the other Participants and Additional Unit Participants, shall offer the Separate Coal Stockpile Participants which are Common Procurement Participants electing to participate in such Common Procurement the opportunity to participate in each such Offer. If two or more of such Common Procurement Participants (including, without limitation, GPC on behalf of the 25 Common Coal Stockpile) elect to participate in any particular Offer, GPC, as agent for the Common Coal Stockpile and each Separate Coal Stockpile Participant which is a Common Procurement Participant shall have the right to participate in such Offer up to the proportion that such Common Procurement Participant's Pro Forma Ownership Interest in Plant Scherer bears to the aggregate of the Pro Forma Ownership Interests in Plant Scherer of all Common Procurement Participants electing to participate in such Offer, and for such purpose, in computing GPC's Pro Forma Ownership Interest in Plant Scherer there shall be added to GPC's Pro Forma Ownership Interest in Plant Scherer the Pro Forma Ownership Interest in Plant Scherer of the other Participants and Additional Unit Participants which are then Common Coal Stockpile Participants. If GPC, as agent for the Common Coal Stockpile, or any of the Separate Coal Stockpile Participants which are Common Procurement Participants elect to participate in any such Offer on a timely basis, GPC will negotiate with the supplier of such Offer in an effort to develop final contract terms and conditions satisfactory to GPC, as agent for the Common Coal Stockpile, and the Separate Coal Stockpile Participants which are Common Procurement Participants electing to participate in such Offer, and GPC, as agent for the Common Coal 26 Stockpile, and each participating Separate Coal Stockpile Participant which is a Common Procurement Participant shall enter into a separate contract with such supplier, which contract for such Separate Coal Stockpile Participant shall provide that GPC shall be the exclusive agent on behalf of such Separate Coal Stockpile Participant for the administration of such contract upon such terms and conditions as are satisfactory to GPC; provided, however, that except as otherwise set forth herein and in the Operating Agreement, such Separate Coal Stockpile Participant shall have sole authority, subject to the policies and procedures adopted or revised from time to time by the Plant Scherer Managing Board, to make or direct major economic decisions which are not administrative in nature, including, without limitation, to extend, terminate or renegotiate the contract or exercise options thereunder and to sue the supplier. GPC makes no representation or warranty that any Common Procurement effort will satisfy either the requirements or the procurement strategy of any Participant or Additional Unit Participant, and GPC shall have no liability to any Participant or Additional Unit Participant in these regards. (C) Separate Procurement. Upon (i) exercise by any Separate Coal Stockpile Participant of a Separate 27 Procurement under Section 2(c)(iii) of the Operating Agreement or (ii) violation by any Separate Coal Stockpile Participant, which has been found by a vote of a majority of the Pro Forma Ownership Interest in Plant Scherer of the Common Procurement Participants (excluding the Pro Forma Ownership Interest in Plant Scherer of the Common Procurement Participant under consideration), of any policy or rule for Common Procurement Participants established from time to time by the Plant Scherer Managing Board, such Separate Coal Stockpile Participant shall immediately cease to be a Common Procurement Participant, and GPC shall have no obligation to procure coal or transportation on behalf of such Separate Coal Stockpile Participant other than for Spot Coal. The remaining Common Procurement Participants owning in the aggregate more than 50% Pro Forma Ownership Interest in Plant Scherer out of the total Pro Forma Ownership Interest in Plant Scherer of the then remaining Common Procurement Participants may vote to reestablish such Separate Coal Stockpile Participant's status as a Common Procurement Participant. Otherwise, GPC shall have no obligation to procure coal or transportation on behalf of any Separate Coal Stockpile Participant which has ceased to be a Common Procurement Participant, other than for Spot Coal. A Separate Procurement Participant shall 28 have no right to receive or review any information relating to any Common Procurement effort or any Offers or contracts resulting from a Common Procurement effort except as may otherwise be provided in subsection (i)(E) of this Section 5(n) relating to Spot Coal. (D) Review of Offers. Any Common Procurement Participant that initiates a Common Procurement and any Common Procurement Participant (other than GPC as agent) that elects to review information relating to any Offer shall pay that portion of the costs of the Common Procurement resulting in such Offer in the proportion that such Common Procurement Participant's Pro Forma Ownership Interest in Plant Scherer bears to the aggregate of the Pro Forma Ownership Interests in Plant Scherer of the Common Procurement Participants participating in such Common Procurement or reviewing any information relating to any Offer, whether or not such Common Procurement Participant elects to participate in any such Offer and all other Common Procurement Participants electing to participate in any such Offer (which shall include the Common Coal Stockpile Participants if GPC, as agent for the Common Coal Stockpile, elects to participate in such Offer) shall each pay a portion of such costs computed on the same basis. Upon request, GPC shall inform a Separate Coal Stockpile Participant which is a Common 29 Procurement Participant that did not initiate the subject Common Procurement of the approximate cost to review the information pertaining to the Offer. No Participant or Additional Unit Participant shall use any information furnished to it by or on behalf of GPC, or any other Common Procurement Participant concerning any such Offers in a manner to prejudice the efforts of GPC and the other Common Procurement Participants in any Common Procurement effort. As to any particular information such prohibition shall terminate two years following the date such information was received by such Participant or Additional Unit Participant. (E) Spot Coal Procurement. Notwithstanding the foregoing provisions of this Section 5(n), the provisions of Section 5(p) of this Agreement and the provisions of Section 2(c) of the Operating Agreement, GPC shall be the exclusive agent to act on behalf of itself and all other Participants and Additional Unit Participants for the procurement, transportation and delivery of Spot Coal. All Offers to sell Spot Coal shall be made available to GPC on its own behalf and on behalf of the other then Common Coal Stockpile Participants, and to each Separate Coal Stockpile Participant (whether or not such Separate Coal Stockpile Participant is then a Common Procurement Participant) on the same basis that an Offer under a 30 Common Procurement is made available to the Common Procurement Participants. GPC shall remain a Common Procurement Participant (both as buyer and seller) so long as there remains one or more other Common Procurement Participants. (ii) Each Participant and each Additional Unit Participant shall have the right to make whatever financial arrangements it may desire, whether by lease, security transaction or otherwise, for the discharge of its fossil fuel payment obligations so long as such arrangements do not adversely affect the rights of the other Participants and Additional Unit Participants. (iii) Except as otherwise agreed by the Common Coal Stockpile Participants or as otherwise provided in Sections 3(b) and 3(d) of the Operating Agreement, the Common Coal Stockpile Participants shall pay Common Coal Stockpile Costs and shall own coal in the Common Coal Stockpile in proportion to their respective undivided ownership interests in the Common Coal Stockpile. (iv) Except as otherwise agreed to by the Participants and Additional Unit Participants or as otherwise provided in Section 3(b) and 3(d) of the Operating Agreement, each Separate Coal Stockpile Participant shall pay all Separate 31 Coal Stockpile Costs which are properly and reasonably allocable to such Separate Coal Stockpile Participant's Separate Coal Stockpile, determined in accordance with GPC's standard accounting practices, which shall comply with the Uniform System of Accounts in effect from time to time except as provided in subsection (viii) of Section 5(p) hereof. (v) Except as otherwise agreed to by the Participants and Additional Unit Participants or as otherwise provided in Section 3(b) and 3(d) of the Operating Agreement, the Participants and Additional Unit Participants shall pay Other Fuel Costs and shall own fossil fuel (other than coal allocated to the Common Coal Stockpile and to the Separate Coal Stockpiles) in proportion to their respective Pro Forma Ownership Interest in Plant Scherer. (vi)(A) If on or prior to 30 days following OPC's receipt of approval of this Amendment from the Administrator of the Rural Electrification Administration, any Participant or Additional Unit Participant exercises its election to become a Separate Coal Stockpile Participant, then within six months following the date of the first election by a Separate Coal Stockpile Participant, or (B) if earlier with respect to Section 3(e)(viii) of the Unit Four Operating Agreement GPC shall develop written procedures for Separate 32 Coal Procurement and Common Procurement and shall submit such procedures to the Plant Scherer Managing Board which shall adopt such procedures by vote of Participants and Additional Unit Participants owning at least an aggregate 85% Pro Forma Ownership Interest in Plant Scherer within two months of submission or which shall revise such procedures, such revisions to be approved by Participants and Additional Unit Participants owning at least an aggregate 85% Pro Forma Ownership Interest in Plant Scherer. In the absence of such adoption or approval of revisions within two months of submission, the procedures submitted by GPC shall go into effect as the procedures adopted by the Plant Scherer Managing Board and may be revised thereafter only by approval of such revisions by Participants and Additional Unit Participants owning at least an aggregate 76% Pro Forma Ownership Interest in Plant Scherer." 12. Amendment to Section 5(p) of the Ownership Agreement. Section 5(p) of the Ownership Agreement is hereby amended by deleting such Section 5(p) in its entirety and by substituting, in lieu thereof, the following: 33 "(p) Common Coal Stockpile and Separate Coal Stockpiles. (i) In order to provide for the ownership by the Participants and the Additional Unit Participants of interests in a Common Coal Stockpile and to provide for the sharing among the Participants and Additional Unit Participants of Common Coal Stockpile Costs, the Participants agree that initially, all Participants and all Additional Unit Participants shall participate in the Common Coal Stockpile. GPC shall cause an adjustment to be made to the account of each Common Coal Stockpile Participant (A) so that the quantity of coal in the Common Coal Stockpile shall thereafter be allocated to the Common Coal Stockpile Participants according to such Common Coal Stockpile Participant's percentage undivided ownership interest in the Common Coal Stockpile as set forth in the following sentence, and (B) so that the average cost per ton or, following a division of the Plant Scherer Coal Stockpile into the Common Coal Stockpile and one or more Separate Coal Stockpiles pursuant to Section 5(p)(iii) of this Agreement, the average cost per British Thermal Unit ("Btu") of the coal in the Common Coal Stockpile is the same for each Common Coal Stockpile Participant, with appropriate charges and credits to be made to the accounts of such 34 Common Coal Stockpile Participants, all in accordance with GPC's standard accounting practices which shall comply with the Uniform System of Accounts in effect from time to time except as provided in subsection (viii) of Section 5(p) hereof. Following each such allocation, each Common Coal Stockpile Participant shall own a percentage undivided ownership interest in the Common Coal Stockpile in the proportion that such Common Coal Stockpile Participant's Pro Forma Ownership Interest in Plant Scherer bears to the aggregate of all Common Coal Stockpile Participants' Pro Forma Ownership Interest in Plant Scherer. (ii) All Common Coal Stockpile Costs incurred in connection with the Common Coal Stockpile shall be allocated among the Common Coal Stockpile Participants at the time such Common Coal Stockpile Costs are incurred in the same respective percentages of each Common Coal Stockpile Participant's undivided ownership interest from time to time in the Common Coal Stockpile at that particular time and, subject to the provisions of Sections 3(b) and 3(d) of the Operating Agreement, the Common Coal Stockpile Costs shall be paid as provided in Sections 5(f) and 5(n) of this Agreement; provided, however, that at the end of each calendar month, GPC shall cause an adjustment to be made among the Common Coal Stockpile Participants in accordance 35 with the amount of coal (or, following a division of the Plant Scherer Coal Stockpile into the Common Coal Stockpile and one or more Separate Coal Stockpiles pursuant to Section 5(p)(iii) of this Agreement, the amount of Btus) actually consumed by each of the Common Coal Stockpile Participant's undivided ownership interest in each of the Units and each of the Additional Units, all in accordance with GPC's standard accounting practices which shall comply with the Uniform System of Accounts in effect from time to time except as provided in subsection (viii) of Section 5(p) hereof. All Other Fuel Costs incurred in connection with the Units and the Additional Units shall be allocated among the Participants and Additional Unit Participants at the time such Other Fuel Costs are incurred in the same respective percentages of each Participant's and Additional Unit Participant's Pro Forma Ownership Interest in Plant Scherer at that particular time, and the Other Fuel Costs shall be paid as provided in Sections 5(f) and 5(n) of this Agreement; provided, however, that at the end of each calendar month, GPC shall cause an adjustment to be made among the Participants and Additional Unit Participants in accordance with the amount of fuel (other than coal) actually consumed by each of the Participants and 36 Additional Unit Participants all in accordance with GPC's standard accounting practices which shall comply with the Uniform System of Accounts in effect from time to time except as provided in subsection (viii) of Section 5(p) hereof. (iii) Each Participant (other than GPC) and each Additional Unit Participant (other than GPC) may elect to discontinue participation in the Common Coal Stockpile by delivery of written notice to GPC of such election not later than 30 days following OPC's receipt of approval of this Amendment from the Administrator of the Rural Electrification Administration. Within six months following the date of the first election by a Separate Coal Stockpile Participant, GPC, as agent for the other Participants and other Additional Unit Participants, shall cause an adjustment to be made to the Common Coal Stockpile and to the account of each Separate Coal Stockpile Participant so that (A) the quantity of coal allocated to the Common Coal Stockpile will equal the percentage undivided ownership interests of the remaining Common Coal Stockpile Participants and so that the quantity of coal allocated to each Separate Coal Stockpile Participant's account will equal its percentage undivided ownership interest in the Common Coal Stockpile at the time such adjustment is made, and (B) the average cost per ton and average cost per Btu 37 for the Common Coal Stockpile and for each Separate Coal Stockpile are the same. GPC shall notify each of the Participants and Additional Unit Participants immediately after such an adjustment has been made of (l) the quantity of coal in the Common Coal Stockpile and in each Separate Coal Stockpile and (2) the average cost per ton and average cost per Btu for the Common Coal Stockpile and for each Separate Coal Stockpile. Thereafter, each Separate Coal Stockpile Participant shall be entitled only to use coal available in its Separate Coal Stockpile account for the operation of its undivided ownership interests in the Units and the Additional Units, and the remaining Common Coal Stockpile Participants shall be entitled to use only coal available in the account of the Common Coal Stockpile for the operation of their undivided ownership interests in the Units and the Additional Units. Except as otherwise provided in subsection (ii) of this Section 5(p), no Participant or Additional Unit Participant shall be required to sell or otherwise supply coal to any other Participant or Additional Unit Participant; however, GPC, on its own behalf and as agent for the other Common Coal Stockpile Participants, and each Separate Coal Stockpile Participant may buy, sell, trade or otherwise supply coal in the Plant Scherer Coal Stockpile from their respective accounts 38 to one another upon such terms as they may agree and upon prior written notice to GPC; provided, however, that all offers to sell coal by a Common Procurement Participant must be offered to all of the Common Procurement Participants on the same basis as an Offer under a Common Procurement. There shall be allocated to each Separate Coal Stockpile Participant's account a portion of subsequent deliveries and associated costs (including, without limitation, "buy-out" costs, if any) from coal contracts identified in Exhibit I hereto (the "Existing Contracts") existing on September 1, 1990 equal to such Separate Coal Stockpile Participant's Pro Forma Ownership Interest in Plant Scherer, and there shall be allocated to each Separate Coal Stockpile Participant's account all coal procured on behalf of such Separate Coal Stockpile Participant by GPC pursuant to Section 5(n) of this Agreement or procured by such Separate Coal Stockpile Participant pursuant to Section 2(c)(iii) of the Operating Agreement; provided, however, that there shall not be added to any Separate Coal Stockpile Participant's Account any additional quantities of coal from Existing Contracts, over and above the deliveries called for from the Existing Contracts, as a result of amendments or modifications to the Existing Contracts after September 1, 1990 without the approval of the Plant 39 Scherer Managing Board by vote of Participants and Additional Unit Participants owning an aggregate of at least 85% Pro Forma Ownership Interests in Plant Scherer. GPC shall account for all coal allocated to the account of each Separate Coal Stockpile Participant and for coal consumed by such Separate Coal Stockpile Participant's undivided ownership interests in the Units and the Additional Units, all in accordance with GPC's standard accounting practices which shall comply with the Uniform System of Accounts in effect from time to time except as provided in subsection (viii) of Section 5(p) hereof. No Separate Coal Stockpile Participant nor any purchaser of an undivided ownership interest in the Units or the Additional Units from a Separate Coal Stockpile Participant may elect to become a Common Coal Stockpile Participant without the written consent of a majority of the Pro Forma Ownership Interest in Plant Scherer of the then remaining Common Coal Stockpile Participants, including, without limitation, GPC so long as GPC is a Participant or Additional Unit Participant. (iv) Except as otherwise provided in subsection (vi) of this Section 5(p), unless otherwise agreed to by Participants and Additional Unit Participants owning in the aggregate at least an 85% Pro Forma Ownership Interest in Plant Scherer, the Participants recognize 40 and agree, as among themselves and for the benefit of the Additional Unit Participants, that the division of the Common Coal Stockpile and each Separate Coal Stockpile is for the purposes only of accounting, payment and settlement of costs and entitlement to use; that there will be no physical separation of coal at Plant Scherer among the Common Coal Stockpile and the Separate Coal Stockpiles and that the Common Coal Stockpile and the Separate Coal Stockpiles will be physically combined and commingled into one common coal stockpile at Plant Scherer; and that existing coal and future deliveries of coal at Plant Scherer allocated among the Common Coal Stockpile and the Separate Coal Stockpiles will all be physically commingled and may be used for the operation of the undivided ownership interests of any Participant or Additional Unit Participant so long as the account of such Participant or Additional Unit Participant demonstrates that there is sufficient coal credited to its account for such operation. Nothing in this Agreement or the Operating Agreement shall preclude Participants and Additional Unit Participants owning in the aggregate at least an 85% Pro Forma Ownership Interest in Plant Scherer from agreeing, upon such terms and conditions as they may agree to, to physically separate the Plant Scherer Coal Stockpile. 41 (v) All discrepancies between the book inventory and the physical inventory of the Plant Scherer Coal Stockpile shall be charged or credited, as appropriate, among the Common Coal Stockpile and the Separate Coal Stockpiles and to the respective accounts of each Participant and each Additional Unit Participant in accordance with the amount of coal actually consumed by the undivided ownership interests of each Participant and each Additional Unit Participant during the physical inventory period to which such discrepancy relates, all as determined in accordance with GPC's standard accounting practices which shall comply with the Uniform System of Accounts in effect from time to time except as provided in subsection (viii) of Section 5(p) hereof. (vi) In the event GPC should be removed as agent for the Participants with respect to the Units, the Plant Scherer Common Facilities or both, the Additional Unit Participants shall have the right at any time thereafter, by vote of whatever percentage such Additional Unit Participants may agree to, not to utilize the Plant Scherer Coal Stockpile, the Common Coal Stockpile, or both, and, in such event, none of the other provisions contained in this Section 5(p) shall thereafter apply to the Additional Units or the Additional Unit Participants; provided, however, that 42 the Additional Unit Participants shall not be released from paying Common Coal Stockpile Costs and Separate Coal Stockpile Costs for which such Additional Unit Participants are otherwise obligated under this Section 5(p). (vii) GPC and each of the other Common Coal Stockpile Participants or any purchaser of an undivided ownership interest in the Units or the Additional Units may enter into whatever other arrangements GPC and such other Common Coal Stockpile Participant (or purchaser) may agree to with respect to such Common Coal Stockpile Participant's (or purchaser's) ownership interest in the Common Coal Stockpile, including, without limitation, the creation of further Separate Coal Stockpiles without requiring the consent of any other Participant or Additional Unit Participant, so long as such arrangement provides for Common Coal Stockpile Costs to be paid as contemplated by this Agreement. (viii)(A) If on or prior to 30 days following OPC's receipt of approval of this Amendment from the Administrator of the Rural Electrification Administration, any Participant or Additional Unit Participant exercises its election to become a Separate Coal Stockpile Participant, then within six months following the date of the first election by a Separate Coal Stockpile Participant, or (B) if earlier with 43 respect to Section 6(i)(viii) of the Unit Four Ownership Agreement, GPC shall develop written procedures for Separate Coal Stockpile accounting and Common Coal Stockpile accounting and shall submit such procedures to the Plant Scherer Managing Board which shall adopt such procedures by vote of Participants and Additional Unit Participants owning at least an aggregate 85% Pro Forma Ownership Interest in Plant Scherer within two months of submission or which shall revise such procedures, such revisions to be approved by Participants and Additional Unit Participants owning at least an aggregate 85% Pro Forma Ownership Interest in Plant Scherer. In the absence of such adoption or approval of revisions within two months of submission, the procedures submitted by GPC shall go into effect as the procedures adopted by the Plant Scherer Managing Board and may be revised thereafter only by approval of such revisions by Participants and Additional Unit Participants owning at least an aggregate 76% Pro Forma Ownership Interest in Plant Scherer." 13. Amendment to Section 6(g) of the Ownership Agreement. The first sentence of the second paragraph of Section 6(g) of the Ownership Agreement is hereby amended to delete the words "and Fuel Costs" and to substitute the words "Common Coal 44 Stockpile Costs, Separate Coal Stockpile Costs, and Other Fuel Costs" therefor. 14. Amendment to Section 9 of the Ownership Agreement. (a) The second sentence of Section 9(u) of the Ownership Agreement is hereby amended to delete the words "Fuel Costs" and to substitute "Common Coal Stockpile Costs, additional Separate Coal Stockpile Costs, additional Other Fuel Costs" therefor. (b) Section 9 of the Ownership Agreement is hereby amended by adding the following new subsection (x) to the end of such Section 9 as follows: "(x) Lessor in Possession. In the event that there occurs a Lessor Possession Date, the Owner Trustee, or any successor to the Owner Trustee's interest in Scherer Unit No. 2, shall become immediately and automatically a Common Coal Stockpile Participant, a Common Dispatch Participant and a Common Procurement Participant for all purposes under this Agreement and under the Operating Agreement. The parties hereto acknowledge that Section 3.1 of the Co-Owners' Consents requires the Owner Trustee to purchase from OPC, and OPC to sell to Owner Trustee, within 120 days after the Lessor Possession Date an amount of coal with a million Btu value equal to X (the "Owner Trustee's Coal Supply"). The amount of coal to be purchased and sold 45 as the Owner Trustee's Coal Supply will be determined by the formula, X = (OT/Y) x Z where: "OT" is equal to the Owner Trustee's Pro Forma Ownership Interest in Plant Scherer; "Y" is equal to the aggregate of the Pro Forma Ownership Interests in Plant Scherer of the then Common Coal Stockpile Participants other than the Owner Trustee (and for this purpose, if there are no Common Coal Stockpile Participants at such time, Y shall be equal to GPC's Pro Forma Ownership Interest in Plant Scherer); and "Z" is equal to the total number of million Btu's in the Common Coal Stockpile (and for this purpose, if there is no Common Coal Stockpile at such time, Z shall be equal to the number of million Btus in GPC's Separate Coal Stockpile); provided, however, if the result of the foregoing calculation would be X = 0, then the Owner Trustee's Coal Supply shall be (and X shall be) equal to the Million Btus in OPC's Separate Coal Stockpile at such time multiplied by a fraction the numerator of which shall be the Owner Trustee's percentage undivided ownership interest in Unit No. 2, and the denominator of which shall be OPC's aggregate 46 percentage undivided leasehold and ownership interest in each of Unit No. 1, Unit No. 2, Unit No. 3 and Unit No. 4 immediately prior to the Lessor Possession Date. If upon a Lessor Possession Date, OPC's coal supply attributable to its interest in Scherer Unit No. 2 is in a Separate Coal Stockpile, the Owner Trustee's Coal Supply shall be calculated as of such Lessor Possession Date and shall immediately and automatically be added to and become a part of the Common Coal Stockpile and shall be accounted for as having been contributed at the then average price per Million Btu of the Common Coal Stockpile. If upon such Lessor Possession Date there are no other Common Coal Stockpile Participants with respect to Scherer Unit No. 2, GPC's coal supply attributable to its interest in Scherer Unit No. 2 shall immediately and automatically be added to and become a part of the Common Coal Stockpile. From and after such Lessor Possession Date, the Owner Trustee shall be a Participant and shall be entitled and subject to the rights and obligations thereof, and the Owner Trustee (and GPC as agent for the Owner Trustee) shall be entitled to use such coal contributed to the Common Coal Stockpile for the benefit of the Owner Trustee even though the purchase and sale of such coal has not been consummated, and from and after such Lessor Possession Date, the Owner Trustee (and its successors and assigns) shall pay its proportionate share of Common Coal Stockpile Costs and Other Fuel Costs. 47 Notwithstanding the foregoing provisions of this Section 9(x), if at such Lessor Possession Date either (i) GPC is no longer a Participant or an Additional Unit Participant, or (ii) GPC has been removed as agent for the Units, and the Additional Unit Participants have discontinued using the Plant Scherer Coal Stockpile; and there is no longer a Common Coal Stockpile for the Units, then the Owner Trustee shall be a Separate Coal Stockpile Participant, the Owner Trustee's Coal Supply shall be equal to OPC's Separate Coal Stockpile as of such Lessor Possession Date multiplied by a fraction, the numerator of which shall be the Owner Trustee's percentage undivided ownership interest in Unit No. 2, and the denominator of which shall be OPC's aggregate percentage undivided leasehold and ownership interest in each of Unit No. 1, Unit No. 2, Unit No. 3 and Unit No. 4 immediately prior to the Lessor Possession Date, and the Owner Trustee shall pay its proportionate share of Separate Coal Stockpile Costs and Other Fuel Costs. OPC hereby agrees to indemnify and hold harmless the other Participants and the Additional Unit Participants (including, without limitation, GPC, as agent, whether it then is or is not a Participant or an Additional Unit Participant) from and against any and all loss, cost, expense or damage (including, without limitation, attorneys' fees and expenses, Cost of Construction, Operating Costs, Separate Coal Stockpile Costs, Common Coal Stockpile Costs or Other Fuel Costs) resulting directly or indirectly from the operation of this subsection, such Lessor's assumption of possession, or both." 48 15. Amendment to Section 10(a) of the Ownership Agreement. Section 10(a) of the Ownership Agreement is hereby amended to delete the last sentence of such Section 10(a). 16. Effectiveness of this Amendment. Neither this Amendment nor any of the obligations of the parties hereto shall be effective until the receipt of all requisite approvals, including, without limitation, the approval of the Securities and Exchange Commission under the Public Utility Holding Company Act of 1935, the written approval of the Administrator of the Rural Electrification Administration and the approval of all other persons and entities having a right to approve or consent to an amendment to the Ownership Agreement, but upon receipt of such approvals this Amendment and the obligations of the parties hereto shall be effective. The parties hereto agree to use their respective best efforts to expeditiously obtain all such requisite approvals. 17. Miscellaneous. Any and all notices, requests, certificates and other instruments executed and delivered after the execution and delivery of this Amendment may refer to the Ownership Agreement without making specific reference to this Amendment, but nevertheless all such references shall be deemed to include this Amendment unless the context shall otherwise require. 49 This Amendment shall be construed in connection with and as a part of the Ownership Agreement, and all terms, conditions and covenants contained in the Ownership Agreement, except as herein modified, shall be and remain in full force and effect, and the parties hereto agree that they are bound by the terms and conditions of the Ownership Agreement as amended hereby. This Amendment may be executed in any number of counterparts, each executed counterpart constituting an original but altogether one and the same instrument.
