      (b) Authority. The execution, delivery and performance by the Borrower of
this Agreement and the other Loan Documents and the performance of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action and do not violate any provision of law or of the
Articles of Incorporation or By-Laws of the Borrower or result in a breach of,
or constitute a default under, any agreement, indenture or other instrument to
which the Borrower is a party or by which it may be bound.

      (c) Consents. No consent, permission, authorization, order or license of
any governmental authority is necessary in connection with the execution,
delivery or performance of the Loan Documents, except such as have been obtained
and are in full force and effect.

      (d) Binding Agreement. Each of the Loan Documents is, or when executed and
delivered will be, the legal, valid, and binding obligation of the Borrower,
enforceable in accordance with its terms, subject only to limitations on
enforceability imposed in equity or by applicable bankruptcy, insolvency,

generally.

      (e) Compliance With Laws. The Borrower is in compliance in all material
respects with all federal, state and local laws, rules, regulations, ordinances,
codes and orders (collectively, "Laws"), the failure to comply with which could
reasonably be expected to have a Material Adverse Effect.

actions or proceedings to which the Borrower is a party or to which any of its
property is subject which, if adversely determined, could reasonably be expected
to have a Material Adverse Effect, and to the best of the Borrower's knowledge,
no such actions or proceedings are threatened or contemplated, except as the
Borrower has disclosed to the RUS in writing.

feasibility studies and other financial information submitted by the Borrower to
the RUS or to any Rating Agency, as updated by the Borrower from time to time
and submitted to the RUS and to the Rating Agencies, in connection with the
restructuring transactions contemplated by the Restructuring Agreement were
reasonable at the time so submitted; and, as of the date hereof, no fact has
come to light, and no event or transaction has occurred, which would cause such
information, as so updated, to be unreasonable.

      (i) Location of Properties. All real property and interests therein of the
Borrower located in the State is located in the counties identified in the

any agreement or instrument to which it is a party or to which any of its
property is subject that could reasonably be expected to have a Material Adverse
Effect.

obligation to make any further advances to the Borrower under the Outstanding
Notes (other than with respect to payments by the Government on account of its
guarantees of certain Outstanding Notes payable to FFB).

Section 3.3 Interest Rates and Payment

      (a) Interest Rates. The Outstanding Notes shall be payable and bear
interest as therein provided.

      (b) Application of Payments. All payments which the Borrower sends to the
RUS on any Outstanding Note shall be applied in the manner provided in the Loan
Documents to which such


                                      -8-


payments relate and in a manner consistent with RUS policies, practices and
procedures for obligations that have been similarly classified by the RUS.

      (c) Electronic Funds Transfer. Except as otherwise prescribed by the RUS,
the Borrower shall make all payments on the Outstanding Notes utilizing
electronic funds transfer procedures as specified by the RUS.

Section 3.4 Prepayment

      The Borrower has no right to prepay any Outstanding Note in whole or in
part except such rights, if any, as are expressly provided for in each
Outstanding Note or as may be provided by Law. However, prepayment of any
Outstanding Note (and any penalties) relating to a Contemporaneous Loan shall be
mandatory under Section 4.3.

                      ARTICLE IV -- AFFIRMATIVE COVENANTS

nature and status thereof.

Section 4.3 Simultaneous Prepayment of Contemporaneous Loans

      If the Borrower shall at any time prepay in whole or in part any
Contemporaneous Loan, the Borrower shall prepay the related Outstanding Note to
the Government in the ratio that the unpaid principal balance of such
Outstanding Note to the Government bears to the aggregate unpaid principal
amount of both such Outstanding Note and the Outstanding Note evidencing the
Contemporaneous Loan. If either such Outstanding Note calls for a prepayment
penalty or premium, such amount shall be paid but shall not be used in computing
the amount needed to be paid to the Government under this Section 4.3 to
maintain such ratio. Prepayments associated with refinancing


                                      -9-


or refunding a Contemporaneous Loan are not considered to be prepayments for
purposes of this Agreement if (i) the principal amount of such refinancing or
refunding loan is not less than the amount of loan principal being refinanced
and (ii) the weighted average life of the refinancing or refunding loan is not
less than the weighted average remaining life of the loan being refinanced.

the RUS under subsection (b) above that shows the Margins for Interest level
required by Section 13.14 of the Indenture was not met for any fiscal year, or
(ii) being notified by the RUS that the Margins for Interest level required by
Section 13.14 of the Indenture was not met for any fiscal year, whichever is

Schedule 2 hereto.

                        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

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.

      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

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

            issuance incurred in connection with a Current Refunding in an

            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

      (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

            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;

            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

            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;

      (x)   create or incur or suffer or permit to be created or incurred or to

            greater than $25,000; provide any Certificate of an Engineer under
            the Indenture, unless such Engineer is a licensed professional, if

            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.

from acting upon any resolution, certificate, statement, instrument, opinion,
report, notice, request, direction, consent, order approval or other paper or
document believed by it to be genuine and to have been signed or presented by

the RUS. Accordingly, this Agreement can be terminated, amended, modified or
supplemented in any way by the Company with the consent of only the RUS and

                   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

                                                                          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

                                                                          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

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

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 Repriced Old Form Note Advance
Portion, and each Retained Repriced 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
IIB of this Retained Indebtedness Note shall govern each Retained Repriced Old
Form Note Advance Portion. The Retained Repriced Old Form Note Advance Portions
are more particularly described in the advance schedules collectively attached
hereto as Annex 2B (any advance schedule constituting a part of Annex 2B being a
"Retained Repriced Old Form Note Advance Portion Schedule," and all of such

4.    Advance Portions Governed by Part IIC ("Retained New Form Note Advance

      (a) Four of the Outstanding Notes were purchased by FFB under an agreement

and restated from time to time prior to January 1, 1992 (each such Outstanding

collectively, the "New Form Notes"). Certain of the Outstanding Note Advances
are evidenced on the date hereof by the New Form Notes (each such Outstanding

date of this Retained Indebtedness Note, GTC assumes a 16.864 percent portion of

      (b) Certain of the Outstanding Note Advances that are evidenced on the

of this Retained Indebtedness Note. The Borrower acknowledges that if the
Borrower makes a Refinancing Election with respect to any Retained Advance

Advance Portion, the interest accrued on such Retained Advance Portion through

       OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 19


                   Part IIB (Retained Repriced Old Form Note Advance Portions)

this paragraph 8. The Late Charge shall accrue from the scheduled date of

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

      thereon through the date of prepayment, plus the prepayment premium
      required by the terms of the Refinancing Authority; and

      in effect, a price for such Retained Repriced Old Form Note Advance
      Portion, and all accrued interest thereon through the date of prepayment,
      that would, if such Retained Repriced Old Form Note Advance Portion were

      the period from the date of purchase to the maturity of such Retained
      Repriced Old 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

      (c) If the Borrower elects to prepay a Portion of a Retained Repriced Old
Form Note Advance Portion, the prepayment price paid shall be applied, first, to
interest accrued on such Portion of the Retained Repriced Old Form Note Advance
Portion to the date of prepayment and, then, to principal installments in the

Repriced Old Form Note Advance Portion, subsequent payments shall continue to be

Advance Portion Schedule, and such payments shall be allocated by FFB between
outstanding principal and accrued interest, as appropriate, until the entire

Advance Portion shall, as to the principal amount of such Portion, be subject to

in writing, and notification of each such Maturity Date, together with evidence
of RUS approval thereof, must be delivered to FFB not less than 3 Business Days
prior to the proposed date for such Maturity Extension in the form prescribed by
FFB for such notification.

4.    Applicable Interest Rate; Establishment of Interest Rate for Maturity
      Extensions; Computation of Interest.

      The interest rate applicable to each Retained New Form Note Advance
Portion shall be the rate specified on the respective Retained New Form Note
Advance Portion Schedule as being the interest rate for such Retained New Form
Note Advance Portion. In the event of a Maturity Extension of any Retained New
Form Note Advance Portion, the interest rate for such Retained New Form Note
Advance Portion, from and after the effective date of such Maturity Extension,
shall be the respective rate that is established by FFB at the time of such
Maturity Extension on the basis of the determination made by the Secretary of
the Treasury pursuant to section 6(b) (12 U.S.C. ss. 2285(b)) of the Federal
Financing Bank Act of 1973, as amended (12 U.S.C. ss. 2281 et seq.) (the "FFB
Act"); provided, however, that the shortest maturity used as the basis for any
rate determination shall be the remaining maturity of the most recently
auctioned 13-week United States Treasury bill. Subject to paragraph 8 of this
Part IIC, interest on each Retained New Form Note Advance Portion shall accrue
from December 31, 1996, to the date on which the principal amount of such
Retained New Form Note Advance Portion is due. Interest on each Retained New
Form Note Advance Portion shall be computed on the basis of (a) actual days
elapsed from (but not including) December 31, 1996, to (and including) the date
on which payment is due, and (b) a year of 365 days (except in calendar years
including February 29, when the basis shall be a 366-day year).

5.    Payment of Interest.

      The interest accrued on each Retained New Form Note Advance Portion shall
be due and payable on each Payment Date, commencing on the first Payment Date to
occur after the effective date of this Retained Indebtedness Note up through and
including the Maturity Date for such Retained New Form Note Advance Portion. The
amount of accrued interest on each Retained New Form Note Advance Portion that
shall be due and payable on each such

                            Part IIC (Retained New Form Note Advance Portions)

Payment Date shall be the amount specified on the respective Retained New Form
Note Advance Portion Schedule as being the amount of accrued interest due and
payable on such Payment Date. 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, the accrued interest on each such Maturity
Extension shall be due and payable on each Payment Date occurring after the
effective date of such Maturity Extension up through and including the Maturity
Date for such Maturity Extension. The amount of accrued interest on each
Maturity Extension that shall be due and payable on each such Payment Date shall
be computed in accordance with the provisions of paragraph 4 of this Part IIC.

6.    Payment of Principal; Principal Payment Options.

      The principal amount of each Retained New Form Note Advance Portion shall
be payable in accordance with the following provisions:

      (a) Principal payments on each Retained New Form Note Advance Portion
shall begin on the date specified on the respective Retained New Form Note
Advance Portion Schedule as being the date for making the first payment of the
principal of such Retained New Form Note Advance Portion (such date being the
"First Principal Payment Date" for such Retained New Form Note Advance Portion)
and shall be made on each subsequent Payment Date until such Retained New Form
Note Advance Portion is paid in full on or before the Final Maturity Date for
such Retained New Form Note Advance Portion; except that, for so long as (1) no
schedule for the payment of the principal of any Retained New Form Note Advance
Portion is specified on any of the Retained New Form Note Advance Portion
Schedules, and (2) the Borrower has not selected a method for the payment of the
principal of any of the Retained New Form Note Advance Portions from among any
of the methods listed in subparagraph (b) of this paragraph 6, the First
Principal Payment Date for such Retained New Form Note Advance Portion may be
deferred by the mutual agreement of the Borrower, RUS, and FFB; provided that a
written amendment to this Note reciting the new and later First Principal
Payment Date shall have been executed by the Borrower and approved by RUS and
delivered to FFB not less than 3 Business Days prior to the then current First
Principal Payment Date.

      (b) If a schedule for the payment of the principal of any Retained New
Form Note Advance Portion is specified on the

       OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 26


                              Part IIC (Retained New Form Note Advance Portions)

respective Retained New Form 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 New Form 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 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.

                              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)

                              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.

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.   Prepayments.

      The Borrower may elect to prepay all or any Portion of the unpaid
principal balance of any Retained New Form 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 New Form 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 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

                              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

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.

the date specified on the respective Retained Refinanced Refinancing Note
Advance Portion Schedule as being the final maturity date for such Retained

that the new Maturity Date for each Maturity Extension shall meet the following
criteria:

            (1) each Maturity Date for a Maturity Extension of a Retained
      Refinanced Refinancing Note Advance Portion shall be a Payment Date;

            (2) no Maturity Date for a Maturity Extension of any Retained

      (c) For each Retained Refinanced Refinancing Note Advance Portion with

      (a) The interest rate applicable to each Retained Refinanced Refinancing
Note Advance Portion shall be the rate specified on the respective Retained

from and after the effective date of such Maturity Extension, shall be the
respective rate that is established by FFB at the time of such Maturity
Extension on the basis of the determination made by the Secretary of the

expenses of FFB and to provide for the accumulation by FFB of reasonable
contingency reserves, assessed by FFB pursuant to section 6(c) of the FFB Act
(12 U.S.C. ss. 2285(c)), shall accrue on each Retained Refinanced Refinancing
Note Advance Portion from December 31, 1996, to the date on which the principal
amount of such Retained Refinanced Refinancing Note Advance Portion is due. The
fee for each

       OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 37


                Part IID (Retained Refinanced Refinancing Note Advance Portions)

Retained Refinanced Refinancing Note Advance Portion shall be equal to
one-eighth of one percent (0.125%) per annum of the unpaid principal balance of
such Retained Refinanced Refinancing Note Advance Portion. The fee on each
Retained Refinanced Refinancing Note Advance Portion shall be computed on the
basis of (1) actual days elapsed from (but not including) December 31, 1996, to
(and including) the date on which payment is due, and (2) a year of 365 days
(except in calendar years including February 29, when the basis shall be a
366-day year).

5.    Payment of interest and Fee.

      The interest accrued on each Retained Refinanced Refinancing Note Advance
Portion and the applicable fee shall be due and payable on each Payment Date,
commencing on the first Payment Date to occur after the effective date of this
Retained Indebtedness Note up through and including the Maturity Date for such
Retained Refinanced Refinancing Note Advance Portion. The amount of accrued
interest on each Retained Refinanced Refinancing Note Advance Portion and the
amount of the applicable fee that shall be due and payable on each such Payment
Date shall be the respective amounts specified on the respective Retained
Refinanced Refinancing Note Advance Portion Schedule as being the amount of
accrued interest and the amount of the applicable fee due and payable on such
Payment Date. 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, the accrued interest on each such Maturity
Extension and the applicable fee shall be due and payable on each Payment Date
occurring after the effective date of such Maturity Extension up through and
including the Maturity Date for such Maturity Extension. The amount of accrued
interest on each Maturity Extension and the amount of the applicable fee that
shall be due and payable on each such Payment Date shall be computed in
accordance with the provisions of paragraph 4 of this Part IID.

6.    Payment of Principal; Principal Payment Options.

      The principal amount of each Retained Refinanced Refinancing Note Advance
Portion shall be payable in accordance with the following provisions:

      (a) Principal payments on each Retained Refinanced Refinancing Note
Advance Portion shall begin on the date specified on the respective Retained
Refinanced Refinancing Note

       OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 38


              Part IID (Retained Refinanced Refinancing Note Advance Portions)

Advance Portion Schedule as being the date for making the first payment of the
principal of such Retained Refinanced Refinancing Note Advance Portion (such
date being the "First Principal Payment Date" for such Retained Refinanced
Refinancing Note Advance Portion) and shall be made on each subsequent Payment
Date until such Retained Refinanced Refinancing Note Advance Portion is paid in
full on or before the Final Maturity Date for such Retained Refinanced
Refinancing Note Advance Portion; except that, for so long as (1) no schedule
for the payment of the principal of any Retained Refinanced Refinancing Note
Advance Portion is specified on any of the Retained Refinanced Refinancing Note
Advance Portion Schedules, and (2) the Borrower has not selected a method for
the payment of the principal of any of the Retained Refinanced Refinancing Note
Advance Portions from among any of the methods listed in subparagraph (b) of
this paragraph 6, the First Principal Payment Date for such Retained Refinanced
Refinancing Note Advance Portion may be deferred by the mutual agreement of the
Borrower, RUS, and FFB; provided that a written amendment to this Note reciting
the new and later First Principal Payment Date shall have been executed by the
Borrower and approved by RUS and delivered to FFB not less than 3 Business Days
prior to the then current First Principal Payment Date.

      (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.

                      REFINANCED RETAINED ADVANCE PORTIONS

1.    Promise to Pay.

      FOR VALUE RECEIVED, the Borrower (which term includes any successors or

the time, in the manner, and with interest at the rates hereinafter provided,
the principal amount of those certain Retained Advance Portions with respect to
which the Borrower makes a Refinancing Election, as provided in paragraph 6 of

respect to which the Borrower makes a Refinancing Election being, from and after
the Refinancing Effective Date for such Refinancing Election, a "Refinanced
Retained Advance Portion," and more than one such Retained Advance Portion
being, collectively, "Refinanced Retained Advances Portions").

2.    Principal Amount of Refinanced Retained Advance Portions.

      The principal amount of each Refinanced Retained Advance Portion shall be
(a) the unpaid principal balance of the respective Retained Advance Portion, as
determined by FFB as of the respective Refinancing Effective Date, plus (b) if
the Borrower has made an Election to Finance the Premium with respect to such
Refinanced Retained Advance Portion, and the condition that applies to making
such Election to Finance the Premium has been satisfied, the amount of the
applicable Refinancing Premium, as provided in the Refinancing Authority.

3.    Maturity Dates; Maturity Extensions; Early Extensions.

      Each Refinanced Retained Advance Portion shall mature on the date
specified in the respective Election Approval Notice (such date being the
"Maturity Date" for such Refinanced Retained Advance Portion), which shall be
the date selected by the Borrower in accordance with the following provisions:

      (a) Each Maturity Date for a Refinanced Retained Advance Portion shall be
a Payment Date.

      (b) No Maturity Date for any Refinanced Retained Advance Portion shall be
later than the date specified on the respective Retained Old Form Note Advance
Portion Schedule, Retained

                                 Part III (Refinanced Retained Advance Portions)

Repriced Old Form Note Advance Portion Schedule, Retained New Form Note Advance
Portion Schedule or Retained Refinanced Refinancing Note Advance Portion
Schedule, as the case may be, for the respective Retained Advance Portion as
being the final maturity date for such Retained Advance portion (such date being
the "Final Maturity Date" for such Refinanced Retained Advance Portion under the
terras of this Part III).

      (c) Each Maturity Date for a Refinanced Retained Advance Portion shall be
at least one calendar quarter from the Refinancing Effective Date for such
Refinanced Retained Advance Portion.

      (d) For each 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 Borrower may, effective as of
such Maturity Date, extend the Maturity Date for such Refinanced Retained
Advance Portion to a new Maturity Date (any such extension, or any subsequent
extension, being a "Maturity Extension"); provided that the new Maturity Date
for each Maturity Extension shall meet the criteria for Maturity Dates
prescribed in subparagraphs (a), (b), and (c) (being at least one calendar
quarter from the effective date of the Maturity Extension) of this paragraph 3.

      (e) For each 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 Borrower may, on any Payment
Date prior to such Maturity Date, extend the Maturity Date for such Refinanced
Retained Advance Portion to a new Maturity Date, including the Final Maturity
Date (any such extension being an "Early Extension"); provided that the Borrower
shall (1) follow the procedures prescribed in subparagraph (a) of paragraph 11
of this Part III for prepaying Refinanced Retained Advance Portions, and (2) pay
FFB, on the effective date of such Early Extension, an amount equal to the
interest accrued on such Refinanced Retained Advance Portion through the
effective date of such Early Extension and the premium, if any, that would be
payable to FFB under subparagraph (b) of paragraph 11 of this Part III if the
Borrower were to prepay such Refinanced Retained Advance Portion on the
effective date of such Early Extension. If the application of the principles of
paragraph 11 of this Part III to any Early Extension shall result in a discount
on the respective Retained New Form Note Advance Portion, such discount will be

                                 Part III (Refinanced Retained Advance Portions)

applied by FFB in the manner requested in writing by the Borrower, with the
written approval of RUS.

      (f) Each selection by the Borrower of a Maturity Date for any Maturity
Extension governed by this Part III must be approved by RUS in writing, and
notification of each such Maturity Date, together with evidence of RUS approval
thereof, must be delivered to FFB not less than 5 Business Days prior to the
proposed date for such Maturity Extension, in the form prescribed by FFB for
such notification.

4.    Establishment of Interest Rate for Refinanced Retained Advance Portions
      and Maturity Extensions; Computation of Interest; Applicable Fee.

      (a) The interest rate for each Refinanced Retained Advance Portion shall
be established by FFB as of the Refinancing Effective Date for such Refinanced
Retained Advance Portion on the basis of a determination made by the secretary
of the Treasury pursuant to the Refinancing Authority; provided, however, that
the shortest maturity used as the basis for any rate determination shall be the
remaining maturity of the most recently auctioned 13-week United States Treasury
bills. In the event of a Maturity Extension of any Refinanced Retained Advance
Portion, the interest rate for such Refinanced Retained Advance Portion, from
and after the effective date of such Maturity Extension, shall be the respective
rate that is established by FFB at the time of such Maturity Extension in
accordance with the principles of the preceding sentences of this paragraph 4.
Subject to paragraph 8 of this Part III, interest on each Refinanced Retained
Advance Portion shall accrue from the Refinancing Effective Date for such
Refinanced Retained Advance Portion to the date on which the principal amount of
such Refinanced Retained Advance Portion is due. Interest on each Refinanced
Retained Advance Portion shall be computed on the basis of (1) actual days
elapsed from (but not including) the Refinancing Effective Date for such
Refinanced Retained Advance Portion to (and including) the date on which payment
is due, and (2) a year of 365 days (except in calendar years including February
29, when the basis shall be a 366-day year).

      (b) In addition to the interest that accrues at a rate determined in
accordance with the preceding subparagraph, a fee to cover all administrative

U.S.C. ss. 2285(c)), shall accrue on each Refinanced Retained Advance Portion
from the Refinancing Effective Date for such Refinanced Retained Advance Portion
to the date on which the principal amount of such Refinanced Retained Advance
Portion is due. The fee for each Refinanced Retained Advance Portion shall be
equal to one-eighth of one percent (0.125%) per annum of the unpaid principal
balance of such Refinanced Retained Advance Portion. The fee on each Refinanced
Retained Advance Portion shall be computed on the basis of (1) actual days
elapsed from (but not including) the Refinancing Effective Date for such
Refinanced Retained Advance Portion to (and including) the date on which payment
is due, and (2) a year of 365 days (except in calendar years including February
29, when the basis shall be a 366-day year).

5.    Payment of Interest and Fee.

      Interest accrued on the outstanding principal amount of each Refinanced
Retained Advance Portion and the applicable fee shall be due and payable on each
Payment Date, commencing on the first Payment Date to occur after the
Refinancing Effective Date for such Refinanced Retained Advance Portion up
through and including the Maturity Date for such Refinanced Retained Advance
Portion. In the event of a Maturity Extension occurring after the Refinancing
Effective Date for any Refinanced Retained Advance Portion, the accrued interest
on each such Maturity Extension and the applicable fee shall be due and payable
on each Payment Date occurring after the effective date of such Maturity
Extension up through and including the Maturity Date for such Maturity
Extension. The amount of accrued interest on each such Maturity Extension and
the applicable fee that shall be due and payable on each such Payment Date shall
be computed in accordance with the provisions of paragraph 4 of this Part III.

6.    Payment of Principal; Principal Payment Options.

      The principal amount of each Refinanced Retained Advance Portion shall be
payable in accordance with the following provisions:

      (a) Principal payments on each Refinanced Retained Advance Portion shall
begin on the first Payment Date to occur after the Refinancing Effective Date
for such Refinanced Retained Advance Portion and shall be made on each
subsequent Payment Date until such Refinanced Retained Advance Portion is paid
in full on or before the Final Maturity Date.

       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. With respect to each Refinanced
Retained Advance Portion for which the Borrower selects the "graduated principal
payments" method for the payment of principal, 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 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.
With respect to each Refinanced Retained Advance Portion for which the Borrower
selects the

       OGLETHORPE POWER CORPORATION RETAINED INDEBTEDNESS NOTE - page 52


                                 Part III (Refinanced Retained Advance Portions)

"level debt service" method for the payment of principal, the level quarterly
payments of principal, accrued interest, and the applicable fee shall be paid on
each Payment Date occurring after the Refinancing Effective Date (or the first
Payment Date to occur after a Maturity Extension) 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.

                                 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.

provided in the Indenture.

shall become due and payable.

      The Corporation on any Payment Date, as hereinabove provided, may pay all
or any part of the principal hereof then outstanding, but so long as any of the
principal hereof shall remain unpaid, the Corporation shall be obligated to make

otherwise agree.

      This Note has been executed, delivered and authenticated pursuant to, and
is secured by, the Indenture, dated as of March 1, 1997, from the Corporation,

modified or amended by one or more indentures or other instruments supplemental
thereto (including Supplemental Indentures as defined therein) entered into
pursuant to the applicable provisions of such Indenture (the "Indenture"). This
Note is an "Existing Obligation" and an "Obligation" (all as defined in the
Indenture) and is entitled to the benefits of the Indenture. Among other things,
the Indenture provides that all Obligations shall be equally and ratably secured
thereby and reference is hereby made to the Indenture for a description of the
property pledged, the nature and extent of the security and the rights of the
holders of Obligations with respect thereto.


      In case of default by the Corporation, as provided in the Indenture, all
principal remaining unpaid on this Note, and all interest thereon, may be
declared or may become due and payable in the manner and with the effect
provided in the Indenture.

      This Note evidences indebtedness created by a loan made under the Rural
Electrification Act of 1936, as amended, including Public Law 93-32.

      If the Government shall at any time assign this Note and insure the
payment hereof, the Corporation shall continue to make payments hereunder to the
Government as collection agent for the insured holder, and, for purposes of the
Indenture, the Government, and not such insured holder, shall be considered to
be, and shall have the rights of, the noteholder.

      This Note is given to evidence a portion of the indebtedness heretofore
evidenced by that certain Mortgage Note, made by the Corporation to the
Government, in the original face amount of $20,987,000, dated November 1, 1984,
as amended by that certain Agreement, dated as of November 3, 1986, by and
between the Government and the Corporation (as so amended, the "Original Note").
In connection with the execution and delivery of this Note, Georgia Transmission
Corporation (An Electric Membership Corporation) has assumed liability for
$2,999,515.57 of the indebtedness originally evidenced by the Original Note, and
the Government has released the Corporation from liability for such assumed
principal amount of the Original Note. From the date of this Note, the
Corporation's liability with respect to the indebtedness evidenced by the
Original Note shall be governed solely by this Note.

      IN WITNESS WHEREOF, the Corporation has caused this Note to be signed in
its corporate name and its corporate seal to be hereunto affixed and attested by
its officers thereunto duly authorized, all as of the day and year first above
