ARTICLE V -- NEGATIVE COVENANTS Section 5.1 General Unless otherwise agreed to in writing by the RUS, while this Agreement is in effect, the Borrower shall duly observe each of the negative covenants set forth in this Article V. Section 5.2 Limitations on System Extensions, Additions and Dispositions (a) Additions to Capacity. The Borrower shall not, without first complying with the requirements of Section 8.1, purchase, construct, lease or otherwise acquire Special Assets (as defined below) if the aggregate amount expended for purchase, construction, lease or other acquisition of all Special Assets (i) in the current fiscal year of the Borrower is greater than 5% of the Borrower's Total Utility Plant or (ii) in the current and two immediately preceding fiscal years of the Borrower is greater than 10% of the Borrower's Total Utility Plant. For the purposes of this Subsection (a), "Special Assets" means capital assets (other than capital assets acquired with at least 85% of the acquisition cost paid from the proceeds of "Non-Recourse Obligations" (as defined in the Wholesale Power Contracts)) that constitute utility or non-utility plant and that: (1) taking into account any substantially contemporaneous or otherwise related sale, transfer, lease or other disposition, increase the generating capacity of the System or any generating plant of the Borrower by more than 5%; (2) are not subject to the lien of the Indenture and are not nuclear fuel; or (3) are not used or useful as a part of the System. (b) Dispositions of System Assets. The Borrower shall not, without first complying with the requirements of Section 8.1, request the release of capital assets that constitute utility plant from the lien of the Indenture pursuant to Section 5.2 of the Indenture if (taking into account any substantially contemporaneous or otherwise related purchase, construction, lease or other acquisition of similar property that is subject to the lien of the Indenture) there will result a decrease in the generating capacity of the System or any generating plant by more than 5% if the aggregate net book value of all such assets released from the lien of the Indenture (i) in the current fiscal year of the Borrower is greater than 5% of the Borrower's Total Utility Plant or (ii) in the current and two immediately preceding fiscal years of the Borrower is greater than 10% of the Borrower's Total Utility Plant. (c) Legal Requirements. The requirements of this Section 5.2 shall not apply to any purchase, construction, lease or other acquisition, or any sale, transfer, lease or other disposition, of -14- capital assets to the extent that any of the foregoing is required to comply with "Legal Requirements" (as defined in the Wholesale Power Contract). No such purchase, construction, lease or other acquisition and no such sale, transfer, lease or other disposition shall be considered in calculating the aggregate limitations specified in Subsections (a) or (b) hereof. (d) Highest Oversight Period. During a Highest Oversight Period, the Borrower shall not, without the prior written approval of the RUS, purchase, construct, lease or otherwise acquire, or sell, transfer, lease or otherwise dispose, of any capital asset, or enter into any agreement therefor. Section 5.3 Limitations on Employment and Retention of General Manager At any time an Event of Default, or an event which with the passage of time or the giving of notice, or both, would become an Event of Default, occurs and is continuing, the Borrower shall not, without the prior written approval of the RUS, enter into an employment relationship with any person to serve as General Manager unless such employment shall first have been approved by the RUS. If an Event of Default, or an event which with the passage of time or the giving of notice, or both, would become an Event of Default, occurs and is continuing and the RUS requests the Borrower to terminate the employment of its General Manager, the Borrower shall do so within thirty (30) days after the date of such request. All contracts in respect of the employment of the General Manager hereafter entered into shall contain provisions to permit compliance with this Section 5.3. Section 5.4 Limitations on Certain Types of Contracts (a) Approval of Certain Contracts. The Borrower shall not, without first complying with the requirements of Section 8.1, enter into any of the following: (i) any contract for the management or operation of all or substantially all of the System; (ii) any contract for the purchase or sale of electric power and energy that has a term exceeding three (3) years and under which committed purchases or sales exceed ten percent (10%) of the peak demand of the System for the most recently completed fiscal year; (iii) any pooling or similar power supply agreement that has a term exceeding three (3) years; or (iv) any amendment or modification to any of the Wholesale Power Contracts, including the Schedules thereto, except that the Borrower may amend or modify any of (A) Exhibits 1 and 2 to "Rate Schedule A" thereto; (B) the Exhibits to Appendix 1 to "Rate Schedule A" thereto in the manner expressly provided in the Wholesale Power Contracts; (C) Sections I and II of -15- Appendix 3 (Control Area Services) to "Rate Schedule A" thereto; (D) Appendix 4 (General Terms and Conditions) to "Rate Schedule A" thereto; (E) Schedule B - Planning and Management of Power Supply Resources for Members in the manner expressly provided in Section 13.3.1 of the Wholesale Power Contracts; and (F) the Wholesale Power Contracts in the manner expressly provided in any "Withdrawal Agreement" (as defined in the Wholesale Power Contracts) entered into in connection with such Wholesale Power Contracts. (b) Terminations. The Borrower shall not, without first complying with the requirements of Section 8.1, exercise any option to terminate any contract, including, without limitation, any Wholesale Power Contract, if such contract, based upon its nature, remaining term (not taking into account any option of the Borrower to terminate) and size, would be required to be approved by the RUS pursuant to Subsection (a) above if the Borrower were to have entered into such contract on the proposed termination date. The Borrower further agrees at the written direction of the RUS to exercise any option to terminate a contract if the exercise by the Borrower of that option would require compliance with Section 8.1 pursuant to the immediately preceding sentence; provided, however, the Borrower shall not be required to exercise any such option to terminate if such exercise could reasonably be expected to have a Material Adverse Effect. For the purpose of illustration only, and not by way of limitation, the Borrower shall be required to comply with Section 8.1 before terminating, and the RUS can require the Borrower to terminate, in any year before year seven (7) thereof, a ten (10) year contract for the sale of electric power and energy that exceeds ten percent (10%) of the Borrower's peak demand because the portion of the contract to be terminated meets the standards of Subsection (a)(ii) above (i.e., a term greater than three (3) years for the committed sale of electric power and energy that exceeds ten percent (10%) of the Borrower's peak demand). The Borrower can terminate without first complying with Section 8.1, and the RUS cannot require the Borrower to terminate, that same contract after year seven (7) thereof. (c) Highest Oversight Period. During a Highest Oversight Period, the Borrower shall not, without the prior written approval of the RUS, enter into or amend or modify any of the contracts of the type described in this Section 5.4, regardless of duration or size. (d) Determination of Term. The term of any contract shall be determined for purposes of this Section 5.4 based solely upon the period prior to the first date upon which the Borrower could, at its option, terminate the contract (taking into account any notice period required for termination), unless the exercise of such termination right could reasonably be expected to have a Material Adverse Effect. (e) Amendments; Extensions. Any amendment or modification to an existing contract (including an extension thereof) shall be governed by this Section 5.4 only to the extent of the specific amendment or modification and not the contract as a whole. -16- Section 5.5 Limitations on Loans, Investments and Other Obligations The Borrower shall not, without first complying with the requirements of Section 8.1, make any Investment, except (i) Investments made for the purpose of funds management that are made pursuant to an investment policy approved by the Borrower's Board of Directors, a copy of which has been provided to the RUS, (ii) Investments specifically approved by the RUS in writing under this clause (ii), and (iii) other Investments that do not in the aggregate with all other Investments other than Investments described in clauses (i) and (ii) above exceed fifteen percent (15%) of the Borrower's Total Utility Plant; provided, however, that during an Increased Oversight Period, the Borrower shall not, without the prior written approval of the RUS, make any additional Investments, except as permitted by the Act and the RUS Regulations; provided, further, however, that during a Highest Oversight Period, the Borrower shall not, without the prior written approval of the RUS, make any additional Investments of any kind. Section 5.6 Depreciation Rates The Borrower shall not, without first complying with the requirements of Section 8.1, adopt any depreciation rate not previously approved for the Borrower by the RUS. Section 5.7 Rate Reductions The Borrower shall not, without first complying with the requirements of Section 8.1, decrease its Rates if it has failed to comply with the provisions of Section 13.14 of the Indenture for the fiscal year prior to such reduction. Section 5.8 Indenture Restrictions Notwithstanding the provisions of the Indenture, the Borrower shall not, without first complying with the requirements of Section 8.1: (i) issue Additional Obligations under the Indenture on the basis of the $200,000,000 carry forward amount described in Section 4.2B(1) of the Indenture, unless the proceeds of such Additional Obligations are used (a) to pay premiums and other penalties and charges in respect of any Existing Obligation held by FFB or the RUS, (b) to fund the acquisition or construction of additions or extensions to the System that are subject to the lien of the Indenture, or (c) to pay premiums and other penalties, charges and other costs of issuance incurred in connection with a Current Refunding in an aggregate amount not to exceed five percent (5%) of the principal amount of the Obligations subject to the Current Refunding; (ii) issue Additional Obligations under the Indenture while any amounts are outstanding under any RUS Reimbursement Obligation or during an Increased Oversight Period or a Highest Oversight Period; -17- (iii) except in connection with a Current Refunding, certify pursuant to Section 4.3D(1) of the Indenture any retired Obligation or any principal payment on an Obligation as the basis for taking any action under the Indenture, if such retirement or payment is pursuant to a regularly scheduled sinking fund or principal installment or made at the Stated Maturity of such Obligation; (iv) consolidate or merge with any other corporation or convey or transfer the Trust Estate under the Indenture substantially as an entirety unless the aggregate amount of the Borrower's Equity is not reduced as a result of such transaction and the Borrower provides the RUS with evidence reasonably satisfactory to the RUS that the consummation of such transaction will not result in the commencement of an Increased Oversight Period; provided, however, that during an Increased Oversight Period or a Highest Oversight Period, the Borrower shall not consolidate or merge with any corporation or convey or transfer the Trust Estate substantially as an entirety; (v) elect pursuant to Section 1.1D of the Indenture to apply Accounting Requirements in effect as of the date of execution and delivery of the Indenture; (vi) include as Property Additions, under any provision of the Indenture, any property that would not qualify as Property Additions but for paragraph C of the definition of Property Additions, or sell, lease or sublease any portion of the Trust Estate pursuant to paragraph H of Section 5.1 of the Indenture; (vii) submit an Available Margins Certificate under Article IV of the Indenture for the purpose of issuing Additional Obligations unless such Certificate is accompanied by an Independent Accountant's Certificate stating in substance that nothing came to the attention of such Accountant in connection with its unaudited review of such period that would lead such Accountant to believe that there was any incorrect or inaccurate statement in such Certificate; (viii) enter into a Supplemental Indenture pursuant to Section 12.1H of the Indenture; (ix) enter into a Supplemental Indenture pursuant to Section 12.1B or 12.1C of the Indenture if (a) the Holders of the Obligations issued under such Supplemental Indenture are granted greater security rights in and to the Trust Estate than those security rights enjoyed by the Government in its capacity as a Holder of Obligations under the Indenture, provided, however, that neither (I) the existence of Credit Enhancement nor (II) the creation and maintenance of debt service or similar funds for the payment of the principal and interest on Obligations issued under such Supplemental Indenture (to the extent such debt service or other similar funds are funded from the proceeds of the issuance of such Obligations or funded in connection with the refinancing of other debt by such Obligations), shall constitute greater -18- security rights in and to the Trust Estate requiring the Borrower to comply with Section 8.1; (b) the Supplemental Indenture provides for covenants, restrictions, limitations, conditions, events of defaults or remedies not applicable to all Obligations then Outstanding or not equally available to all Holders of Obligations then Outstanding, provided, however, that provisions for covenants and events of default that relate solely to assuring that the interest on such Obligations (or other indebtedness secured by such Obligations) is excludable from the gross income of the holder thereof pursuant to the Internal Revenue Code, as amended, shall not constitute the providing of covenants or events of default requiring the Borrower to comply with Section 8.1; or (c) the Obligations issued under such Supplemental Indenture, or the indebtedness secured by such Obligations, can be accelerated, or effectively accelerated through a mandatory purchase or similar mechanism, as a consequence of a breach or default by the Borrower under the related loan agreement or similar agreement entered into in connection with such Obligation or indebtedness, provided, however, that acceleration and similar rights may be granted to development authorities and trustees without first complying with Section 8.1 in connection with the issuance of Obligations (or other indebtedness secured by such Obligations) the interest on which is excludable from the gross income of the holder thereof pursuant to the Internal Revenue Code, as amended, if such acceleration and similar rights are substantially similar to those currently granted to development authorities and trustees in connection with the Existing Obligations;

provide any Certificate of an Engineer under the Indenture, unless such Engineer is a licensed professional, if the amount of the property as to which the Engineer's Certificate applies is greater than $100,000; or provide any Certificate of an Engineer under the Indenture, unless such Engineer is Independent, if the amount of the property as to which the Engineer's Certificate applies is greater than $10,000,000.

RETAINED INDEBTEDNESS NOTE PART I DESCRIPTION OF RETAINED INDEBTEDNESS NOTE 1. Retained Indebtedness Note to Evidence Indebtedness for which Oglethorpe Power Corporation Remains Liable after Georgia Transmission Corporation's Assumption of a 16.864 Percent Portion of Indebtedness Evidenced by Oglethorpe Power Corporation's Outstanding Notes. This Retained Indebtedness Note is executed and delivered to evidence (a) the present obligations of OGLETHORPE POWER CORPORATION (AN ELECTRIC MEMBERSHIP GENERATION AND TRANSMISSION CORPORATION) (the "Borrower"), a corporation organized and existing under the laws of the State of Georgia, to the FEDERAL FINANCING BANK ("FFB") remaining after the assumption by Georgia Transmission Corporation (An Electric Membership Corporation) ("GTC"), a corporation organized and existing under the laws of the State of Georgia, of a 16.864 percent portion of the indebtedness that is presently owed by the Borrower to FFB on account of certain advances of funds previously made by FFB that are outstanding on the date hereof and evidenced on the date hereof by those certain promissory notes payable to FFB OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 1 Part I previously executed and delivered by the Borrower, which notes are more particularly described on the list of notes attached hereto as Annex 1 (each note listed on Annex 1, as such note may have been amended, being an "Outstanding Note," all such notes being, collectively, the "Outstanding Notes", the indebtedness of the Borrower presently owed to FFB on account of each advance of funds previously made by FFB that is outstanding on the date hereof and evidenced on the date hereof by an outstanding Note being an "Outstanding Note Advance", and the indebtedness of the Borrower presently owed to FFB on account of more than one such advance of funds being, collectively, "Outstanding Note Advances"), and (b) certain obligations of the Borrower to the Administrator of the Rural Utilities Service ("RUS"), successor to the Administrator of the Rural Electrification Administration ("REA"), remaining after the assumption by the GTC of a 16.864 percent portion of the obligations of the Borrower to the Administrator of RUS relating to such assumed indebtedness. 2. Advance Portions Governed by Part IIA ("Retained Old Form Note Advance Portions"). (a) Five of the Outstanding Notes were purchased by FFB under an agreement dated as of August 14, 1974, between FFB and REA, as such agreement was amended from time to time prior to January 28, 1983 (each such Outstanding Note being an "Old Form Note", and all five of such Outstanding Notes being, collectively, the "Old Form Notes"). Each of these Old Form Notes has previously been modified, respectively, by an agreement among the Borrower, FFB, and REA which established the procedures for the Borrower to elect to have a new interest rate apply to any Outstanding Note Advance that was evidenced on the date of such modification agreement by an Old Form Note and was outstanding more than 12 years after the end of the calendar year in which such Outstanding Note Advance was made (any election to have a new interest rate apply to any such Outstanding Note Advance being a "repricing" of such outstanding Note Advance, and any modification agreement establishing the procedures for repricing any such outstanding Note Advances being a "Repricing Agreement"). Certain of the Outstanding Note Advances that are evidenced on the date hereof by an Old Form Note that has been modified by a Repricing Agreement have not been repriced as of the date hereof under such Repricing Agreement (each such outstanding Note Advance being an "Old Form Note Advance", and more than one such Outstanding Note Advance being, collectively, "Old Form Note Advances"). Effective as of the date of this Retained Indebtedness Note, GTC assumes a 16.864 percent portion OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 2 Part I of each Old Form Note Advance (the 16.864 percent portion of each Old Form Note Advance, which portion is assumed by GTC as of the date hereof, being an "Assumed Old Form Note Advance Portion"), leaving the residual 83.136 percent portion of each Old Form Note Advance remaining owed by the Borrower to FFB (the 83.136 percent portion of each Old Form Note Advance, which portion remains owed by the Borrower to FFB, being a "Retained Old Form Note Advance Portion", and all of such percent portions remaining owed by the Borrower to FFB being, collectively, the "Retained Old Form Note Advance Portions"). Upon execution by RUS of the guarantee set forth at the end of this Retained Indebtedness Note, the Borrower shall be released from any and all liability for each Assumed Old Form Note Advance Portion, and each Retained Old Form Note Advance Portion shall be evidenced by this Retained Indebtedness Note. Subject to the exercise of the refinancing election provided in paragraph 6 of this Part I, the terms of Part IIA of this Retained Indebtedness Note shall govern each Retained Old Form Note Advance Portion. The Retained Old Form Note Advance Portions are more particularly described in the advance schedules collectively attached hereto as Annex 2A (any advance schedule constituting a part of Annex 2A being a "Retained Old Form Note Advance Portion Schedule," and all of such advance schedules being, collectively, the "Retained Old Form Note Advance Portion Schedules"). (b) The Refinancing Note dated as of March 31, 1994, is one of the Outstanding Notes and was accepted by FFB in substitution for a promissory note payable to FFB that was previously executed and delivered by the Borrower, purchased by FFB under an agreement dated as of August 14, 1974, between FFB and REA, as such agreement was amended from time to time prior to January 28, 1983, and modified by a Repricing Agreement among the Borrower, FFB, and REA (the Outstanding Note so accepted being the "Refinancing Note"). The Refinancing Note established the procedures for the Borrower to elect to refinance under section 306C of the Rural Electrification Act of 1936, as amended (7 U.S.C. ss. 936c) (the "Refinancing Authority"), any Outstanding Note Advance that was evidenced on the date of the Refinancing Note by the Refinancing Note. Certain Outstanding Note Advances that are evidenced on the date hereof by the Refinancing Note and identified in the Refinancing Note as being "Old Form Note Advances" have not been refinanced as of the date hereof under the Refinancing Authority (each such Outstanding Note Advance being included within the term "Old Form Note Advance", and all of such Outstanding Note Advances being collectively included within the term "Old Form Note Advances"). Effective as of the OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 3 Part I date of this Retained Indebtedness Note, GTC assumes a 16.864 percent portion of each such Old Form Note Advance (the 16.864 percent portion of each such Old Form Note Advance, which portion is assumed by GTC as of the date hereof, being included within the term "Assumed Old Form Note Advance Portion"), leaving the residual 83.136 percent portion of each such Old Form Note Advance remaining owed by the Borrower to FFB (the 83.136 percent portion of each such Old Form Note Advance, which portion remains owed by the Borrower to FFB, being included within the term "Retained Old Form Note Advance Portion", and all of such percent portions remaining owed by the Borrower to FFB being collectively included within the term "Retained Old Form Note Advance Portions"). Upon execution by RUS of the guarantee set forth at the end of this Retained Indebtedness Note, the Borrower shall be released from any and all liability for each such Assumed Old Form Note Advance Portion, and each such Retained Old Form Note Portion shall be evidenced by this Retained Indebtedness Note. Subject to the exercise of the refinancing election provided in paragraph 6 of this Part I, the terms of Part IIA of this Retained Indebtedness Note shall also govern each such Retained Old Form Note Advance Portion. Such Retained Old Form Note Advance Portions are more particularly described in advance schedules that are included among the Retained Old Form Note Advance Portion Schedules attached hereto as Annex 2A. 3. Advance Portions Governed by Part IIB ("Retained Repriced Old Form Note Advance Portions"). Certain of the Outstanding Note Advances that are evidenced on the date hereof by an Old Form Note that has been modified by a Repricing Agreement have been repriced prior to the date hereof under a Repricing Agreement (each such Outstanding Note Advance being a "Repriced Old Form Note Advance", and more than one such Outstanding the Borrower Advance being, collectively, "Repriced Old Form Note Advances"). Effective as of the date of this Retained Indebtedness Note, GTC assumes a 16.864 percent portion of each Repriced Old Form Note Advance (the 16.864 percent portion of each Repriced Old Form Note Advance, which portion is assumed by GTC as of the date hereof, being an "Assumed Repriced Old Form Note Advance Portion"), leaving the residual 83.136 percent portion of each Repriced Old Form Note Advance remaining owed by the Borrower to FFB (the 83.136 percent portion of each Repriced Old Form Note Advance, which portion remains owed by the Borrower to FFB, being a "Retained Repriced Old Form Note Advance Portion", and all of such percent portions remaining owed by the Borrower to FFB being, collectively, the "Retained Repriced Old OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 4 Part I Form Note Advance Portions").

If a schedule for the payment of the principal of any Retained New Form Note Advance Portion is not specified on any of the Retained New Form Note Advance Portion Schedules, then the Borrower must select, subject to RUS approval, a method for the payment of principal when the Borrower first selects a Maturity Date for a Retained New Form Note Advance Portion that occurs on or after the First Principal Payment Date for such Retained New Form Note Advance Portion. The Borrower shall select a method for the payment of principal from among the following options: (1) "equal principal payments" -- the amount of each quarterly principal payment shall substantially equal the amount of every other quarterly principal payment; (2) "graduated principal payments" -- the amount of each of the first one-third (or nearest number of payments that rounds to one-third) of the total number of quarterly principal payments shall substantially equal one-half of the amount of each of the remaining quarterly principal payments; (3) "level debt service" -- the amount of each quarterly payment of principal and accrued interest shall substantially equal the amount of every other quarterly payment. (c) In the event of a Maturity Extension occurring after the date of this Retained Indebtedness Note with respect to any Retained New Form Note Advance Portion not having a schedule for the payment of principal specified on the respective Retained New Form Note Advance Portion Schedule: (1) if the Borrower selects the "equal principal payments" method for the payment of the principal of such Retained New Form Note Advance Portion at the time of such Maturity Extension, then the level quarterly payments of principal, along with accrued interest on the unpaid principal balance, shall be paid on each Payment Date beginning on the First Principal Payment Date and ending on the Final Maturity Date for such Retained New Form Note Advance Portion; OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 27 Part IIC (Retained New Form Note Advance Portions) (2) if the Borrower selects the "graduated principal payments" method for the payment of the principal of such Retained New Form Note Advance Portion at the time of such Maturity Extension, then the graduated quarterly payments of principal, along with accrued interest on the unpaid principal balance, shall be paid on each Payment Date beginning on the First Principal Payment Date and ending on the Final Maturity Date for such Retained New Form Note Advance Portion; and (3) if the Borrower selects the "level debt service" method for the payment of the principal of such Retained New Form Note Advance Portion at the time of such Maturity Extension, then the level quarterly payments of principal and accrued interest (subject to adjustment in the event of any subsequent Maturity Extensions as hereinafter provided) shall be paid on each Payment Date beginning with the First Principal Payment Date and ending on the Final Maturity Date for such Retained New Form Note Advance Portion. (d) In the event of a Maturity Extension occurring after the date of this Retained Indebtedness Note with respect to any Retained New Form Note Advance Portion having a schedule for the payment of principal specified on the respective Retained New Form Note Advance Portion Schedule, or any Retained New Form Note Advance Portion with respect to which the Borrower has previously selected a method for the payment of the principal of such Retained New Form Note Advance Portion: (1) if the principal payment schedule specified was determined using the "equal principal payments" method, or if the method selected for the payment of principal was the "equal principal payments" method, then the level quarterly payments of principal that are due and payable on each Payment Date occurring after the effective date of such Maturity Extension shall be the same as the level quarterly payments of principal that were due and payable on each Payment Date occurring before the effective date of such Maturity Extension; (2) if the principal payment schedule specified was determined using the "graduated principal payments" method, or if the method selected for the payment of principal was the "graduated principal payments" method, then the graduated quarterly payments of principal that are due and OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 28 Part IIC (Retained New Form Note Advance Portions) payable on each Payment Date occurring after the effective date of such Maturity Extension shall be determined with reference to the date on which the first payment of principal was due and payable by the Borrower under the terms of the respective New Form Note, and not with reference to first Payment Date to occur after the effective date of the Maturity Extension; and (3) if the principal payment schedule specified was determined using the "level debt service" method, or if the method selected for the payment of principal was the "level debt service" method, then the level quarterly payments of principal and accrued interest that are due and payable on each Payment Date occurring after the effective date such Maturity Extension shall be newly determined taking into account the new interest rate that is applicable to such Retained New Form Note Advance Portion from and after the effective date of such Maturity Extension. (e) If a schedule for the payment of the principal of any Retained New Form Note Advance Portion is specified on the respective Retained New Form Note Advance Portion Schedule, the Borrower may not change such principal payment schedule, except as hereinafter provided. In the event of a Maturity Extension occurring after the date of this Retained Indebtedness Note with respect to any Retained New Form Note Advance Portion not having a schedule for the payment of principal through the Maturity Date thereof specified on the respective Retained New Form Note Advance Portion Schedule, and the Borrower selects a method for the payment of principal from among the methods listed in subparagraph (b) of this paragraph 6, the Borrower may not change the resulting principal payment schedule, except as hereinafter provided. The Borrower may change the method of payment of the principal of any Retained New Form Note Advance Portion having a Maturity Date that occurs prior to the Final Maturity Date for such Retained New Form Note Advance Portion from either the "equal principal payments" method or the "graduated principal payments" method to the "level debt service" method at the time, if ever, of a Maturity Extension of such Retained New Form Note Advance Portion, effective on the date of such Maturity Extension. After the Borrower selects the Final Maturity Date as being the Maturity Date for a Maturity Extension of any Retained New Form Note Advance Portion, no changes in the resulting principal payment schedule may be made and no more Maturity Extensions may occur for such Retained New Form Note Advance Portion. OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 29 Part IIC (Retained New Form Note Advance Portions) (f) The entire unpaid principal amount of any Retained New Form Note Advance Portion having a Maturity Date that occurs prior to the Final Maturity Date for such Retained New Form Note Advance Portion shall be due and payable on such Maturity Date, subject to Maturity Extensions in accordance with paragraph 3 of this Part IIC. In the event of a Maturity Extension of any Retained New Form Note Advance Portion having a Maturity Date that occurs on or after the First Principal Payment Date but prior to the Final Maturity Date for such Retained New Form Note Advance Portion, the principal payment that is due according to the resulting principal payment schedule shall nevertheless be due and payable on the Maturity Date, notwithstanding such Maturity Extension. (g) Notwithstanding which of the 3 methods listed in subparagraph (b) of this paragraph 6 is selected for the payment of principal of any Retained New Form Note Advance Portion, the aggregate of all quarterly payments on such Retained New Form Note Advance Portion shall be such as will pay the entire principal amount of such Retained New Form Note Advance Portion, and all interest accrued thereon, on or before the Final Maturity Date for such Retained New Form Note Advance Portion. 7. Business Days. Whenever any Payment Date or the Maturity Date for any Retained New Form Note Advance Portion shall fall on a day which is not a Business Day, the payment that would otherwise be due on such Payment Date or Maturity Date shall be due on the first Business Day thereafter. In the case of a Payment Date for a Maturity Extension of any Retained New Form Note Advance Portion falling on a day other than a Business Day, the extension of time for making the payment that would otherwise be due on such Payment Date shall (a) be taken into account in establishing the interest rate for the respective Maturity Extension of the Retained New Form Note Advance Portion, and (b) be included in computing interest in connection with such payment and excluded in connection with the next payment. In the case of the Maturity Date for a maturity Extension of any Retained New Form Note Advance Portion falling on a day other than a Business Day, the extension of time for making the payment that would otherwise be due on such Maturity Date shall (a) be taken into account in establishing the interest rate for the respective Maturity Extension of the Retained New Form Note Advance Portion, and (b) OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 30 Part IIC (Retained New Form Note Advance Portions) be included in computing interest in connection with such payment. 8. Late Charges. If any payment of any amount owing under any Retained New Form Note Advance Portion is not made when and as due (any such amount being then an "Overdue Amount"), the amount payable shall be such Overdue Amount plus interest thereon (such interest being the "Late Charge") computed in accordance with this paragraph 8. The Late Charge shall accrue from the scheduled date of payment for the Overdue Amount (taking into account paragraph 7 of this Part IIC) to the actual date on which payment is made. The Late Charge shall be computed on the basis of (a) actual days elapsed from (but not including) the scheduled date of payment for such Overdue Amount (taking into account paragraph 7 of this Part IIC) to (and including) the date on which payment is made, and (b) a year of 365 days (except in calendar years including February 29, when the basis shall be a 366-day year). The Late Charge shall accrue at a rate (the "Late Charge Rate") equal to one and one-half times the rate to be determined by the Secretary of the Treasury taking into consideration the prevailing market yield on the remaining maturity of the most recently auctioned 13-week United States Treasury bills. The initial Late Charge Rate shall be in effect until either the actual date of payment or the next succeeding Payment Date, whichever occurs first. If the Overdue Amount and the amount of accrued Late Charge are not paid on or before the next succeeding Payment Date, then an amount equal to the amount of accrued Late Charge shall be added to the Overdue Amount, and the amount then payable shall be the sum of the Overdue Amount and the amount of accrued Late Charge, plus a Late Charge on such sum accruing at a new Late Charge Rate to be then determined in accordance with the principles of the second preceding sentence. For so long as any Overdue Amount remains unpaid, the Late Charge Rate shall be redetermined in accordance with the principles of the third preceding sentence on each succeeding Payment Date and shall be applied to the Overdue Amount and all amounts of accrued Late Charge to the actual date of payment. Nothing in this paragraph shall be construed as permitting or implying that the Borrower may, without the written consent of FFB, modify, extend, alter or affect in any manner whatsoever (except as explicitly provided herein) the right of FFB to receive any and all payments on account of Retained New Form Note Advance Portions on the dates specified in this Part IIC. OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 31 Part IIC (Retained New Form Note Advance Portions) 9. Final Due Date. Notwithstanding anything in this Retained Indebtedness Note to the contrary, all amounts outstanding under this Retained Indebtedness Note on account of each Retained New Form Note Advance Portion, which amounts remain unpaid as of the Final Maturity Date for such Retained New Form Note Advance Portion, shall be due and payable on the Final Maturity Date for such Retained New Form Note Advance Portion. 10. Application of Payments. Each payment made on any Retained New Form Note Advance Portion shall be applied first to the payment of any Late Charge payable under paragraph 8 of this Part IIC, then to the payment of any premium payable under paragraph 11 of this Part IIC, then to the payment of accrued interest, then on account of outstanding principal, and then to the payment of the fee payable under paragraph 2 of Part IV of this Retained Indebtedness Note. 11.

(b) The Borrower shall pay to FFB, at the time of prepayment of all or any Portion of any Retained New Form Note Advance Portion: (1) for so long as the Refinancing Authority shall be in effect, the outstanding principal amount of such Retained New Form Note Advance Portion or the Portion thereof to be prepaid, all accrued interest thereon through the date of prepayment, plus the prepayment premium required by the terms of the Refinancing Authority; and OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 32 Part IIC (Retained New Form Note Advance Portions) (2) in the event that the Refinancing Authority shall no longer be in effect, a price for such Retained New Form Note Advance Portion, and all accrued interest thereon through the date of prepayment, that would, if such Retained New Form Note Advance Portion were purchased and held to its maturity, produce a yield to the purchaser for the period from the date of purchase to the maturity of such Retained New Form Note Advance Portion substantially equal to the interest rate that would be set on a loan from the Secretary of the Treasury to FFB to purchase an obligation having a payment schedule identical to that of such Retained New Form Note Advance Portion; and if the Borrower elects to repurchase a Portion of a Retained New Form Note Advance Portion, the Borrower shall pay to FFB a price for such Portion that would equal such Portion's pro rata share of the price for a repurchase of the entire Retained New Form Note Advance Portion, calculated in accordance with the principles of this sentence. The amount of each such prepayment premium or prepayment price, as the case may be, shall be calculated by the Secretary of the Treasury as of the close of business 2 Business Days prior to the date of the proposed prepayment, using standard calculation methods of the United States Department of the Treasury. (c) If the Borrower elects to prepay a Portion of a Retained New Form Note Advance Portion, the prepayment price paid shall be applied, first, to interest accrued on such Portion of the Retained New Form Note Advance Portion to the date of prepayment and, then, to principal installments in the inverse order of maturity. Following the prepayment of a Portion of a Retained New Form Note Advance Portion, subsequent payments shall continue to be made in the amounts specified in the respective Retained New Form Note Advance Portion Schedule, if a schedule for the payment of principal is specified on such Retained New Form Note Advance Portion Schedule, or, if not, then in accordance with the payment schedule resulting from the method for the payment of principal selected under subparagraph (b) of paragraph 6 of this Part IIC, until the entire principal amount of such Retained New Form Note Advance Portion, and all accrued interest thereon, is paid; except that, with respect to any Retained New Form Note Advance Portion for which the Borrower has selected the "level debt service" method under subparagraph (b) of paragraph (6) of this Part IIC, payments shall continue to be made in accordance with the level debt service payment schedule that resulted when the Borrower first selected the level debt OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 33 Part IIC (Retained New Form Note Advance Portions) service method, and such payments shall be allocated by FFB between outstanding principal and accrued interest, as appropriate, until the entire principal amount of such Retained New Form Note Advance Portion, and all interest accrued thereon, is paid. (d) Any prepayment of a Portion of a Retained New Form Note Advance Portion shall, as to the principal amount of such Portion, be subject to a minimum amount equal to $100,000.00 of principal. (e) The provisions of this paragraph 11 shall apply to all prepayments of any Retained New Form Note Advance Portion, regardless whether such prepayments are made pursuant to the refinancing Authority or otherwise.

(b) If a schedule for the payment of the principal of any Retained Refinanced Refinancing Note Advance Portion is specified on the respective Retained Refinanced Refinancing Note Advance Portion Schedule, then the amount of principal due and payable on each such Payment Date shall be the amount specified on the respective Retained Refinanced Refinancing Note Advance Portion Schedule as being the amount of principal due and payable on such Payment Date. If a schedule for the payment of the principal of any Retained Refinanced Refinancing Note Advance Portion is not specified on any of the Retained Refinanced Refinancing Note Advance Portion Schedules, then the Borrower must select, subject to RUS approval, a method for the payment of principal when the Borrower first selects a Maturity Date for a Retained Refinanced Refinancing Note Advance Portion that occurs on or after the First Principal Payment Date for such Retained Refinanced Refinancing Note Advance Portion. The Borrower shall select a method for the payment of principal from among the following options: (1) "equal principal payments" -- the amount of each quarterly principal payment shall substantially equal the amount of every other quarterly principal payment; OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 39 Part IID (Retained Refinanced Refinancing Note Advance Portions) (2) "graduated principal payments" -- the amount of each of the first one-third (or nearest number of payments that rounds to one-third) of the total number of quarterly principal payments shall substantially equal one-half of the amount of each of the remaining quarterly principal payments; (3) "level debt service" -- the amount of each quarterly payment of principal, accrued interest, and the applicable fee shall substantially equal the amount of every other quarterly payment. (c) In the event of a Maturity Extension occurring after the date of this Retained Indebtedness Note with respect to any Retained Refinanced Refinancing Note Advance Portion not having a schedule for the payment of principal specified on the respective Retained Refinanced Refinancing Note Advance Portion Schedule: (1) if the Borrower selects the "equal principal payments" method for the payment of the principal of such Retained Refinanced Refinancing Note Advance Portion at the time of such Maturity Extension, then the level quarterly payments of principal, along with accrued interest on the unpaid principal balance and the applicable fee, shall be paid on each Payment Date beginning on the First Principal Payment Date and ending on the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion; (2) if the Borrower selects the "graduated principal payments" method for the payment of the principal of such Retained Refinanced Refinancing Note Advance Portion at the time of such Maturity Extension, then the graduated quarterly payments of principal, along with accrued interest on the unpaid principal balance and the applicable fee, shall be paid on each Payment Date beginning on the First Principal Payment Date and ending on the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion; and (3) if the Borrower selects the "level debt service" method for the payment of the principal of such Retained Refinanced Refinancing Note Advance Portion at the time of such Maturity Extension, then the level quarterly payments of principal, accrued interest, and the applicable fee (subject to adjustment in the event of any subsequent Maturity Extensions as hereinafter provided) shall be paid OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 40 Part IID (Retained Refinanced Refinancing Note Advance Portions) on each Payment Date beginning with the First Principal Payment Date and ending on the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion. (d) In the event of a Maturity Extension occurring after the date of this Retained Indebtedness Note with respect to any Retained Refinanced Refinancing Note Advance Portion having a schedule for the payment of principal specified on the respective Retained Refinanced Refinancing Note Advance Portion Schedule, or any Retained Refinanced Refinancing Note Advance Portion with respect to which the Borrower has previously selected a method for the payment of the principal of such Retained Refinanced Refinancing Note Advance Portion: (1) if the principal payment schedule specified was determined using the "equal principal payments" method, or if the method selected for the payment of principal was the "equal principal payments" method, then the level quarterly payments of principal that are due and payable on each Payment Date occurring after the effective date of such Maturity Extension shall be the same as the level quarterly payments of principal that were due and payable on each Payment Date occurring before the effective date of such Maturity Extension; (2) if the principal payment schedule specified was determined using the "graduated principal payments" method, or if the method selected for the payment of principal was the "graduated principal payments" method, then the graduated quarterly payments of principal that are due and payable on each Payment Date occurring after the effective date of such Maturity Extension shall be determined with reference to the date on which the first payment of principal was due and payable by the Borrower under the terms of the respective Refinanced Refinancing Note, and not with reference to first Payment Date to occur after the effective date of the Maturity Extension; and (3) if the principal payment schedule specified was determined using the "level debt service" method, or if the method selected for the payment of principal was the "level debt service" method, then the level quarterly payments of principal, accrued interest, and the applicable fee that are due and payable on each Payment Date occurring after the effective date such Maturity Extension shall be newly determined taking into account the new interest rate that is OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 41 Part IID (Retained Refinanced Refinancing Note Advance Portions) applicable to such Retained Refinanced Refinancing Note Advance Portion from and after the effective date of such Maturity Extension. (e) If a schedule for the payment of the principal of any Retained Refinanced Refinancing Note Advance Portion is specified on the respective Retained Refinanced Refinancing Note Advance Portion Schedule, the Borrower may not change such principal payment schedule, except as hereinafter provided. In the event of a Maturity Extension occurring after the date of this Retained Indebtedness Note with respect to any Retained Refinanced Refinancing Note Advance Portion not having a schedule for the payment of principal through the Maturity Date thereof specified on the respective Retained Refinanced Refinancing Note Advance Portion Schedule, and the Borrower selects a method for the payment of principal from among the methods listed in subparagraph (b) of this paragraph 6, the Borrower may not change the resulting principal payment schedule, except as hereinafter provided. The Borrower may change the method of payment of the principal of any Retained Refinanced Refinancing Note Advance Portion having a Maturity Date that occurs prior to the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion from either the "equal principal payments" method or the "graduated principal payments" method to the "level debt service" method at the time, if ever, of a Maturity Extension of such Retained Refinanced Refinancing Note Advance Portion, effective on the date of such Maturity Extension. After the Borrower selects the Final Maturity Date as being the Maturity Date for a Maturity Extension of any Retained Refinanced Refinancing Note Advance Portion, no changes in the resulting principal payment schedule may be made and no more Maturity Extensions may occur for Such Retained Refinanced Refinancing Note Advance Portion. (f) The entire unpaid principal amount of any Retained Refinanced Refinancing Note Advance Portion having a Maturity Date that occurs prior to the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion shall be due and payable on such Maturity Date, subject to Maturity Extensions in accordance with paragraph 3 of this Part IID. In the event of a Maturity Extension of any Retained Refinanced Refinancing Note Advance Portion having a Maturity Date that occurs on or after the First Principal Payment Date but prior to the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion, the principal payment that is due according to the resulting principal payment schedule shall nevertheless be due OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 42 Part IID (Retained Refinanced Refinancing Note Advance Portions) and payable on the Maturity Date, notwithstanding such Maturity Extension. (g) Notwithstanding which of the 3 methods listed in subparagraph (b) of this paragraph 6 is selected for the payment of principal of any Retained Refinanced Refinancing Note Advance Portion, the aggregate of all quarterly payments on such Retained Refinanced Refinancing Note Advance Portion shall be such as will pay the entire principal amount of such Retained Refinanced Refinancing Note Advance Portion, and all interest accrued thereon and the applicable fee, on or before the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion. 7. Business Days. Whenever any Payment Date or the Maturity Date for any Retained Refinanced Refinancing Note Advance Portion shall fall on a day which is not a Business Day, the payment that would otherwise be due on such Payment Date or Maturity Date shall be due on the first Business Day thereafter. In the case of a Payment Date for a Maturity Extension of any Retained Refinanced Refinancing Note Advance Portion falling on a day other than a Business Day, the extension of time for making the payment that would otherwise be due on such Payment Date shall (a) be taken into account in establishing the interest rate for the respective Maturity Extension of the Retained Refinanced Refinancing Note Advance Portion, and (b) be included in computing interest and the applicable fee in connection with such payment and excluded in connection with the next payment. In the case of the Maturity Date for a Maturity Extension of any Retained Refinanced Refinancing Note Advance Portion falling on a day other than a Business Day, the extension of time for making the payment that would otherwise be due on such Maturity Date shall (a) be taken into account in establishing the interest rate and the applicable fee for the respective Maturity Extension of the Retained Refinanced Refinancing Note Advance portion, and (b) be included in computing interest in connection with such payment. 8. Late Charges. If any payment of any amount owing under any Retained Refinanced Refinancing Note Advance Portion is not made when and as due (any such amount being then an "Overdue Amount"), the amount payable shall be such Overdue Amount plus interest thereon (such interest being the "Late Charge") computed in accordance OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 43 Part IID (Retained Refinanced Refinancing Note Advance Portions) with this paragraph 8. The Late Charge shall accrue from the scheduled date of payment for the Overdue Amount (taking into account paragraph 7 of this Part IID) to the actual date on which payment is made. The Late Charge shall be computed on the basis of (a) actual days elapsed from (but not including) the scheduled date of payment for such Overdue Amount (taking into account paragraph 7 of this Part IID) to (and including) the date on which payment is made, and (b) a year of 365 days (except in calendar years including February 29, when the basis shall be a 366-day year). The Late Charge shall accrue at a rate (the "Late Charge Rate") equal to one and one-half times the rate to be determined by the Secretary of the Treasury taking into consideration the prevailing market yield on the remaining maturity of the most recently auctioned 13-week United States Treasury bills. The initial Late Charge Rate shall be in effect until either the actual date of payment or the next succeeding Payment Date, whichever occurs first. If the Overdue Amount and the amount of accrued Late Charge are not paid on or before the next succeeding Payment Date, then an amount equal to the amount of accrued Late Charge shall be added to the Overdue Amount, and the amount then payable shall be the sum of the Overdue Amount and the amount of accrued Late Charge, plus a Late Charge on such sum accruing at a new Late Charge Rate to be then determined in accordance with the principles of the second preceding sentence. For so long as any Overdue Amount remains unpaid, the Late Charge Rate shall be redetermined in accordance with the principles of the third preceding sentence on each succeeding Payment Date and shall be applied to the Overdue Amount and all amounts of accrued Late Charge to the actual date of payment. Nothing in this paragraph shall be construed as permitting or implying that the Borrower may, without the written consent of FFB, modify, extend, alter or affect in any manner whatsoever (except as explicitly provided herein) the right of FFB to receive any and all payments on account of Retained Refinanced Refinancing Note Advance Portions on the dates specified in this Part IID. 9. Final Due Date. Notwithstanding anything in this Retained Indebtedness Note to the contrary, all amounts outstanding under this Retained Indebtedness Note on account of each Retained Refinanced Refinancing Note Advance Portion, which amounts remain unpaid as of the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion, shall be due and payable on the Final Maturity Date for such Retained Refinanced Refinancing Note Advance Portion. OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 44 Part IID (Retained Refinanced Refinancing Note Advance Portions) 10. Application of Payments. Each payment made on any Retained Refinanced Refinancing Note Advance Portion shall be applied first to the payment of any Late Charge payable under paragraph 8 of this Part IID, then to the payment of any premium payable under paragraph 11 of this Part IID, then to the payment of accrued interest and the amount of the applicable fee payable under paragraph 4 of this Part IID, then on account of outstanding principal, and then to the payment of the fee payable under paragraph 2 of Part IV of this Retained Indebtedness Note. 11. Prepayments. The Borrower may elect to prepay all or any Portion of the unpaid principal balance of any Retained Refinanced Refinancing Note Advance Portion in the manner, at the price, and subject to the limitations as next described: (a) The Borrower shall deliver to FFB written notification of such prepayment election not less than 5 Business Days prior to the proposed date of prepayment and, if less than the total outstanding principal amount of such Retained Refinanced Refinancing Note Advance Portion is to be prepaid, the Borrower shall specify in such notification the Portion thereof that is proposed to be prepaid. (b) The Borrower shall pay to FFB, at the time of prepayment of all or any Portion of any Retained Refinanced Refinancing Note Advance Portion: (1) for so long as the Refinancing Authority shall be in effect, the outstanding principal amount of the Retained Refinanced Refinancing Note Advance Portion or the Portion thereof to be prepaid, all accrued interest thereon through the date of prepayment, the applicable fee through the date of prepayment, plus the prepayment premium required by the terms of the Refinancing Authority; and (2) in the event that the Refinancing Authority shall no longer be in effect, a price for such Retained Refinanced Refinancing Note Advance Portion, and all accrued interest thereon through the date of prepayment and the applicable fee through the date of prepayment, that would, if such Retained Refinanced Refinancing Note Advance Portion were purchased and held to its maturity, produce a yield to the OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 45 Part IID (Retained Refinanced Refinancing Note Advance Portions) purchaser for the period from the date of purchase to the maturity of such Retained Refinanced Refinancing Note Advance Portion substantially equal to the interest rate that would be set on a loan from the Secretary of the Treasury to FFB to purchase an obligation having a payment schedule identical to that of such Retained Refinanced Refinancing Note Advance Portion; and if the Borrower elects to repurchase a Portion of a Retained Refinanced Refinancing Note Advance Portion, the Borrower shall pay to FFB a price for such Portion that would equal such Portion's pro rata share of the price for a repurchase of the entire Retained Refinanced Refinancing Note Advance Portion, calculated in accordance with the principles of this sentence. The amount of each such prepayment premium or prepayment price, as the case may be, shall be calculated by the Secretary of the Treasury as of the close of business 2 Business Days prior to the date of the proposed prepayment, using standard calculation methods of the United States Department of the Treasury. (c) If the Borrower elects to prepay a Portion of a Retained Refinanced Refinancing Note Advance Portion, the prepayment price paid shall be applied, first, to accrued interest on such Portion of the Retained Refinanced Refinancing Note Advance Portion to the date of prepayment and the applicable fee to the date of prepayment and, then, to principal installments in the inverse order of maturity. Following the prepayment of a Portion of a Retained Refinanced Refinancing Note Advance Portion, subsequent payments shall continue to be made in the amounts specified in the respective Retained Refinanced Refinancing Note Advance Portion Schedule, if a schedule for the payment of principal is specified on such Retained Refinanced Refinancing Note Advance Portion Schedule, or, if not, then in accordance with the payment schedule resulting from the method for the payment of principal selected under subparagraph (b) of paragraph 6 of this Part IID, until the entire principal amount of the Retained Refinanced Refinancing Note Advance Portion, and all interest accrued thereon and the applicable fee, is paid; except that, with respect to any Retained Refinanced Refinancing Note Advance Portion for which the Borrower has selected the "level debt service" method under subparagraph (b) of paragraph 6 of this Part IID, payments shall continue to be made in accordance with the level debt service payment schedule that resulted when the Borrower first selected the level debt service method, and such payments shall be allocated by FFB among outstanding principal, accrued interest, and the applicable fee, OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 46 Part IID (Retained Refinanced Refinancing Note Advance Portions) as appropriate, until the entire principal amount of such Retained Refinanced Refinancing Note Advance Portion, and all interest accrued thereon and the applicable fee, is paid. (d) Any prepayment of a Portion of a Retained Refinanced Refinancing Note Advance Portion shall, as to the principal amount of such Portion, be subject to a minimum amount equal to $100,000.00 of principal. (e) The provisions of this paragraph 11 shall apply to all prepayments of any Retained Refinanced Refinancing Note Advance Portion, regardless whether such prepayments are made pursuant to the Refinancing Authority or otherwise.

OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 51 Part III (Refinanced Retained Advance Portions) (b) When the Borrower selects a Maturity Date for any Refinanced Retained Advance Portion, the Borrower must also select, subject to RUS approval, a method for the payment of principal from among the following options: (1) "equal principal payments" -- the amount of each quarterly principal payment shall substantially equal the amount of every other quarterly principal payment; (2) "graduated principal payments" -- the amount of each of the first one-third (or nearest number of payments that rounds to one-third) of the total number of quarterly principal payments shall substantially equal one-half of the amount of each of the remaining quarterly principal payments; (3) "level debt service" -- the amount of each quarterly payment of principal, accrued interest, and the applicable fee shall substantially equal the amount of every other quarterly payment. Approval of the Borrower's selection of a method for the payment of principal may be withheld by RUS if RUS determines, in its sole discretion, that the method selected by the Borrower would increase RUS's risk under its guarantee of this Retained Indebtedness Note. (c) With respect to each Refinanced Retained Advance Portion for which the Borrower selects the "equal principal payments" method for the payment of principal, the level quarterly payments of principal, along with accrued interest on the unpaid principal balance and the applicable fee, shall be paid on each Payment Date occurring after the Refinancing Effective Date for such Refinanced Retained Advance Portion and ending on the Final Maturity Date for such Refinanced Retained Advance Portion.

(d) After the Borrower selects one of the 3 methods listed in subparagraph (b) of this paragraph 6 for the payment of principal of any Refinanced Retained Advance Portion, the resulting principal payment schedule for that Refinanced Retained Advance Portion may not be changed; except that the Borrower may change the method of payment of the principal of any Refinanced Retained Advance Portion with respect to which the Borrower selects a Maturity Date that occurs prior to the Final Maturity Date for such Refinanced Retained Advance Portion from either the "equal principal payments" method or the "graduated principal payments" method to the "level debt service" method at the time, if ever, of a Maturity Extension of such Refinanced Retained Advance Portion, effective on the date of such Maturity Extension. After the Borrower selects the Final Maturity Date as being the Maturity Date for any Refinanced Retained Advance Portion or a Maturity Extension of any Refinanced Retained Advance Portion, no changes in the resulting principal repayment schedule may be made and no more Maturity Extensions may occur for such Refinanced Retained Advance Portion. (e) The entire unpaid principal amount of any Refinanced Retained Advance Portion with respect to which the Borrower selects a Maturity Date that occurs prior to the Final Maturity Date for such Refinanced Retained Advance Portion shall be due and payable on such Maturity Date, subject to Maturity Extensions in accordance with paragraph 3 of this Part III. In the event of a Maturity Extension of any Refinanced Retained Advance Portion with respect to which the Borrower selects a Maturity Date that occurs prior to the Final Maturity Date for such Refinanced Retained Advance Portion, the principal payment that is due according to the resulting principal payment schedule shall nevertheless be due and payable on the Maturity Date, notwithstanding such Maturity Extension. (f) Notwithstanding which of the 3 methods listed in subparagraph (b) of this paragraph 6 is selected for the payment of principal of any Refinanced Retained Advance Portion, the aggregate of all quarterly payments on such Refinanced Retained OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 53 Part III (Refinanced Retained Advance Portions) Advance Portion shall be such as will pay the entire principal amount of such Refinanced Retained Advance Portion, and all interest and the applicable fee accrued thereon, on or before the Final Maturity Date for such Refinanced Retained Advance Portion. 7. Business Days. Whenever any Payment Date or the Maturity Date for any Refinanced Retained Advance Portion shall fall on a day which is not a Business Day, the payment that would otherwise be due on such Payment Date or Maturity Date shall be due on the first Business Day thereafter. In the case of a Payment Date for any Refinanced Retained Advance Portion falling on a day other than a Business Day, the extension of time for making the payment that would otherwise be due on such Payment Date shall (a) be taken into account in establishing the interest rate for the respective Refinanced Retained Advance Portion, and (b) be included in computing interest and the applicable fee in connection with such payment and excluded in connection with the next payment. In the case of the Maturity Date for any Refinanced Retained Advance Portion falling on a day other than a Business Day, the extension of time for making the payment that would otherwise be due on such Maturity Date shall (a) be taken into account in establishing the interest rate for the respective Refinanced Retained Advance Portion, and (b) be included in computing interest and the applicable fee in connection with such payment. 8. Late Charges. If any payment of any amount owing on account of any Refinanced Retained Advance Portion is not made when and as due (any such amount being then an "Overdue Amount"), the amount payable shall be such Overdue Amount plus interest thereon (such interest being the "Late Charge") computed in accordance with this paragraph 8. The Late Charge shall accrue from the scheduled date of payment for the Overdue Amount (taking into account paragraph 7 of this Part III) to the actual date on which payment is made. The Late Charge shall be computed on the basis of (a) actual days elapsed from (but not including) the scheduled date of payment for such Overdue Amount (taking into account paragraph 7 of this Part III) to (and including) the date on which payment is made, and (b) a year of 365 days (except in calendar years including February 29, when the basis shall be a 366-day year). The Late Charge shall accrue at a rate (the "Late Charge Rate") equal to one and one-half times the rate to be determined by the Secretary of the Treasury taking into consideration the OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 54 Part III (Refinanced Retained Advance Portions) prevailing market yield on the remaining maturity of the most recently auctioned 13-week United States Treasury bills. The initial Late Charge Rate shall be in effect until either the actual date of payment or the next succeeding Payment Date, whichever occurs first. If the Overdue Amount and the amount of accrued Late Charge are not paid on or before the next succeeding Payment Date, then an amount equal to the amount of accrued Late Charge shall be added to the Overdue Amount, and the amount then payable shall be the sum of the Overdue Amount and the amount of accrued Late Charge, plus a Late Charge on such sum accruing at a new Late Charge Rate to be then determined in accordance with the principles of the second preceding sentence. For so long as any Overdue Amount remains unpaid, the Late Charge Rate shall be redetermined in accordance with the principles of the third preceding sentence on each succeeding Payment Date, and shall be applied to the Overdue Amount and all amounts of accrued Late Charge to the actual date of payment. Nothing in this paragraph shall be construed as permitting or implying that the Borrower may, without the written consent of FFB, modify, extend, alter or affect in any manner whatsoever (except as explicitly provided herein) the right of FFB to receive any and all payments on account of all Refinanced Retained Advance Portions on the dates specified in this Part III. 9. Final Due Date. Notwithstanding anything in this Retained Indebtedness Note to the contrary, all amounts outstanding under this Retained Indebtedness Note on account of each Refinanced Retained Advance Portion, which amounts remain unpaid as of the Final Maturity Date for such Refinanced Retained Advance Portion, shall be due and payable on the Final Maturity Date for such Refinanced Retained Advance Portion. 10. Application of Payments. Each payment made on any Refinanced Retained Advance Portion shall be applied first to the payment of any Late Charge payable under paragraph 8 of this Part III, then to the payment of any premium payable under paragraph 11 of this Part III, then to the payment of accrued interest and the applicable fee payable under paragraph 4 of this Part III, then on account of outstanding principal, and then to the payment of the fee payable under paragraph 2 of Part IV of this Retained Indebtedness Note. OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 55 Part III (Refinanced Retained Advance Portions) 11. Prepayments. The Borrower may elect to prepay all or any portion of the unpaid principal balance of any Refinanced Retained Advance Portion in the manner, at the price, and subject to the limitations as next described: (a) The Borrower shall deliver to FFB written notification of such prepayment election not less than 5 Business Days prior to the proposed date of prepayment and, if less than the total outstanding principal amount of such Refinanced Retained Advance Portion is to be prepaid, the Borrower shall specify in such notification the amount that is proposed to be prepaid (any amount of a Refinanced Retained Advance Portion which is less than the total outstanding principal amount of the respective Refinanced Retained Advance Portion being a "Portion"). (b) The Borrower shall pay to FFB, at the time of prepayment of all or any Portion of any Refinanced Retained Advance Portion: (1) for so long as the Refinancing Authority shall be in effect, the outstanding principal amount of the Refinanced Retained Advance Portion, or Portion thereof, to be prepaid, all accrued interest thereon through the date of prepayment, the applicable fee through the date of prepayment, plus the prepayment premium required by the terms of the Refinancing Authority; and (2) in the event that the Refinancing Authority shall no longer be in effect, a price for such Refinanced Retained Advance Portion, and all accrued interest thereon through the date of prepayment and the applicable fee through the date of prepayment, that would, if such Refinanced Retained Advance Portion were purchased and held to its maturity, produce a yield to the purchaser for the period from the date of purchase to the maturity of such Refinanced Retained Advance Portion substantially equal to the interest rate that would be set on a loan from the Secretary of the Treasury to FFB to purchase an obligation having a payment schedule identical to that of such Refinanced Retained Advance Portion; and if the Borrower elects to repurchase a Portion of a Refinanced Retained Advance Portion, the Borrower shall pay to FFB a price for such Portion that would equal such Portion's pro rata share of the price for a repurchase of the entire Refinanced Retained Advance OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 56 Part III (Refinanced Retained Advance Portions) Portion, calculated in accordance with the principles of this sentence. The amount of each such prepayment premium or prepayment price, as the case may be, shall be calculated by the Secretary of the Treasury as of the close of business 2 Business Days prior to the date of the proposed prepayment, using standard calculation methods of the United States Department of the Treasury. (c) If the Borrower elects to prepay a Portion of a Refinanced Retained Advance Portion, the prepayment price paid shall be applied, first, to accrued interest on such Portion and the applicable fee to the date of prepayment and, then, to principal installments in the inverse order of maturity. Following the prepayment of a Portion of a Refinanced Retained Advance Portion, subsequent payments shall continue to be made in accordance with the payment schedule resulting from the method for the payment of principal selected under subparagraph (b) of paragraph 6 of this Part III, until the entire principal amount of the Refinanced Retained Advance Portion, and all accrued interest thereon and the applicable fee, is paid; except that, with respect to any Refinanced Retained Advance Portion for which the Borrower has selected the "level debt service" method under subparagraph (b) of paragraph 6 of this Part III, payments shall continue to be made in accordance with the level debt service payment schedule that resulted when the Borrower first selected the level debt service method, and such payments shall be allocated by FFB among outstanding principal, accrued interest, and the applicable fee, as appropriate, until the entire principal amount of such Refinanced Retained Advance Portion, and all accrued interest thereon and the applicable fee, is paid. (d) Any prepayment of a Portion of a Refinanced Retained Advance Portion shall, as to the principal amount of such Portion, be subject to a minimum amount equal to $100,000.00 of principal. (e) The provisions of this paragraph 11 shall apply to all prepayments of any Refinanced Retained Advance Portion, regardless whether such prepayment is made pursuant to the Refinancing Authority or otherwise.
