RECORDING TAX PURSUANT TO THE RULES AND REGULATIONS OF THE STATE OF GEORGIA §560-11-8-.14(d).

  
        THIS FIFTY-SIXTH SUPPLEMENTAL INDENTURE, dated as of November 1, 2010, is between OGLETHORPE POWER
CORPORATION (AN ELECTRIC MEMBERSHIP CORPORATION), formerly known as Oglethorpe Power Corporation (An Electric Membership Generation & Transmission Corporation), an
electric membership corporation organized and existing under the laws of the State of Georgia, as grantor (the "Company"), and U.S. BANK NATIONAL
ASSOCIATION, a national banking association, as successor to SunTrust Bank, formerly known as SunTrust Bank, Atlanta, as trustee (in such capacity, the "Trustee"). 

        WHEREAS, the Company has heretofore executed and delivered to the Trustee an Indenture, dated as of March 1, 1997 (the "Original
Indenture"), for the purpose of securing its Existing Obligations and providing for the authentication and delivery of Additional Obligations by the Trustee from time to time under the Original
Indenture (capitalized terms used herein and not otherwise defined shall have the meanings assigned to them in the Original Indenture); 

        WHEREAS, the Company has heretofore executed and delivered to the Trustee fifty-five Supplemental Indentures (the Original
Indenture, as heretofore, hereby and hereafter supplemented and modified, the "Indenture"), and the Original Indenture and the fifty-five Supplemental Indentures have been recorded as set
forth on Schedule 1; 

        WHEREAS, the Board of Directors of the Company has authorized a new series of Additional Obligations to be designated the First Mortgage
Bonds, Series 2010 A, due November 1, 2040 in the principal amount of Four Hundred and Fifty Million Dollars ($450,000,000) (the "Series 2010 A Bonds"); 

        WHEREAS, the Company has registered the Series 2010 A Bonds under the Securities Act of 1933, as amended (the "Securities Act"),
with the Securities and Exchange Commission (the "SEC"); 

        WHEREAS, the Company has complied or will comply with all provisions required to issue Additional Obligations provided for in the Original
Indenture; 

        WHEREAS, the Company desires to execute and deliver this Fifty-Sixth Supplemental Indenture, in accordance with the provisions of the
Original Indenture, for the purpose of providing for the creation and designation of the Series 2010 A Bonds as Additional Obligations and specifying the form and provisions thereof; 

        WHEREAS, Section 12.1 of the Original Indenture provides that, without the consent of the Holders of any of the Obligations at the
time Outstanding, the Company, when authorized by a Board Resolution, and the Trustee may enter into Supplemental Indentures for the purposes and subject to the conditions set forth in said
Section 12.1, including to create additional series of Obligations under the Indenture and to make provisions for such additional series of Obligations; and 

        WHEREAS, all acts and proceedings required by law and by the Articles of Incorporation and Bylaws of the Company necessary to secure under
the Indenture the payment of the principal of (and premium, if any) and interest on the Series 2010 A Bonds, to make the Series 2010 A Bonds to be issued hereunder, when executed by the
Company, authenticated and delivered by the Trustee and duly issued, the valid, binding and legal obligation of the Company, and to constitute the Indenture a valid and binding lien for the security
of the Series 2010 A Bonds, in accordance with its terms, have been done and taken; and the execution and delivery of this Fifth-Sixth Supplemental Indenture has been in all respects duly
authorized by the Company; 

        NOW, THEREFORE, THIS FIFTY-SIXTH SUPPLEMENTAL INDENTURE WITNESSES, that, to secure the payment of the principal of (and premium, if any)
and interest on the Outstanding Secured Obligations, including, when authenticated and delivered, the Series 2010 A Bonds, to confirm the lien of the Indenture upon the Trust Estate, including
property purchased, constructed or otherwise acquired by the Company since the date of execution of the Original Indenture, to secure performance of the covenants therein and herein contained, to
declare the terms and conditions on which the Series 2010 A Bonds are secured, and in consideration of the premises thereof and hereof, the Company by these presents does grant, bargain, sell,
alienate, remise, release, convey, assign, transfer, 

 

mortgage,
hypothecate, pledge, set over and confirm to the Trustee, and its successors and assigns in the trust created thereby and hereby, in trust, all property, rights, privileges and franchises
(other than Excepted Property or Excludable Property) of the Company, whether now owned or hereafter acquired, of the character described in the Granting Clauses of the Original Indenture, wherever
located, including all such property, rights, privileges and franchises acquired since the date of execution of the Original Indenture, including, without limitation, all property described on  Exhibit A attached hereto, subject to all exceptions, reservations and matters of the character referred to in the Indenture, and does grant a
security interest therein for the purposes expressed herein and in the Original Indenture
subject in all cases to Sections 5.2 and 11.2 B of the Original Indenture and to the rights of the Company under the Original Indenture, including the rights set forth in Article V
thereof; but expressly excepting and excluding from the lien and operation of the Indenture all properties of the character specifically excepted as "Excepted Property" or "Excludable Property" in the
Original Indenture to the extent contemplated thereby. 

        PROVIDED, HOWEVER, that if, upon the occurrence of an Event of Default, the Trustee, or any separate trustee or co-trustee
appointed under Section 9.14 of the Original Indenture or any receiver appointed pursuant to statutory provision or order of court, shall have entered into possession of all or substantially
all of the Trust Estate, all the Excepted Property described or referred to in Paragraphs A through H, inclusive, of "Excepted Property" in the Original Indenture then owned or thereafter
acquired by the Company, shall immediately, and, in the case of any Excepted Property described or referred to in Paragraphs I, J, L, N and P of "Excepted Property" in the Original Indenture
(excluding the property described in Section 2 of Exhibit B in the Original Indenture), upon demand of the Trustee or such other trustee
or receiver, become subject to the lien of the Indenture to the extent permitted by law, and the Trustee or such other trustee or receiver may, to the extent permitted by law, at the same time
likewise take possession thereof, and whenever all Events of Default shall have been cured and the possession of all or substantially all of the Trust Estate shall have been restored to the Company,
such Excepted Property shall again be excepted and excluded from the lien of the Indenture to the extent and otherwise as hereinabove set forth and as set forth in the Indenture. 

        The
Company may, however, pursuant to the Granting Clause Third of the Original Indenture, subject to the lien of the Indenture any Excepted Property or Excludable Property, whereupon
the same shall cease to be Excepted Property or Excludable Property. 

        TO HAVE AND TO HOLD all such property, rights, privileges and franchises hereby and hereafter (by a Supplemental Indenture or otherwise)
granted, bargained, sold, alienated, remised, released, conveyed, assigned, transferred, mortgaged, hypothecated, pledged, set over or confirmed as aforesaid, or intended, agreed or covenanted so to
be, together with all the tenements, hereditaments and appurtenances thereto appertaining (said properties, rights, privileges and franchises, including any cash and securities hereafter deposited or
required to be deposited with the Trustee (other than any such cash which is specifically stated in the Indenture not to be deemed part of the Trust Estate) being part of the Trust Estate), unto the
Trustee, and its successors and assigns in the trust herein created by the Indenture, forever. 

        SUBJECT, HOWEVER, to (i) Permitted Exceptions and (ii) to the extent permitted by Section 13.6 of the Original
Indenture as to property hereafter acquired (a) any duly recorded or perfected prior mortgage or other lien that may exist thereon at the date of the acquisition thereof by the Company and

        BUT IN TRUST, NEVERTHELESS, with power of sale, for the equal and proportionate benefit and security of the Holders from time to time of
all the Outstanding Secured Obligations without any priority of any such Obligation over any other such Obligation and for the enforcement of the payment of such Obligations in accordance with their
terms. 

        UPON CONDITION that, until the happening of an Event of Default and subject to the provisions of Article V of the Original
Indenture, and not in limitation of the rights elsewhere provided in the Original Indenture, including the rights set forth in Article V of the Original Indenture, the Company shall be
permitted to (i) possess and use the Trust Estate, except cash, securities, Designated Qualifying Securities and other personal property deposited, or required to be deposited, with the
Trustee, (ii) explore for, mine, extract, separate and dispose of coal, ore, gas, oil and other minerals, and harvest standing timber, and (iii) receive and use the rents, issues,
profits, revenues and other income, products and proceeds of the Trust Estate. 

        THE INDENTURE, INCLUDING THIS FIFTY-SIXTH SUPPLEMENTAL INDENTURE, is intended to operate and is to be construed as a deed passing title to
the Trust Estate and is made under the provisions of the laws of the State of Georgia relating to deeds to secure debt, and not as a mortgage or deed of trust, and is given to secure the Outstanding
Secured Obligations. Should the indebtedness secured by the Indenture be paid according to the tenor and effect thereof when the same shall become due and payable and should the Company perform all
covenants contained in the Indenture in a timely manner, then the Indenture shall be canceled and surrendered. 

        AND IT IS HEREBY COVENANTED AND DECLARED that the Series 2010 A Bonds are to be authenticated and delivered and the Trust Estate is
to be held and applied by the Trustee, subject to the covenants, conditions and trusts set forth herein and in the Indenture, and the Company does hereby covenant and agree to and with the Trustee,

    THE SERIES 2010 A BONDS AND
  CERTAIN PROVISIONS RELATING THERETO    
    

        Section 2.1    Terms of the Series 2010 A
Bonds. 

        There
shall be established a series of Additional Obligations known as and entitled the "First Mortgage Bonds, Series 2010 A" (the "Series 2010 A Bonds"). 

        The
aggregate principal amount of the Series 2010 A Bonds which may be authenticated and delivered and Outstanding at any one time is limited to Four Hundred and Fifty Million
Dollars ($450,000,000). The Series 2010 A Bonds shall consist of bonds in an aggregate principal amount of $450,000,000, due November 1, 2040. 

        The
Series 2010 A Bonds shall bear interest from their date of issuance, payable semi-annually on May 1 and November 1 of each year, commencing on
May 1, 2011. The Series 2010 A Bonds shall bear interest at the annual rate of 5.375%. 

        The
principal and the Redemption Price of, and interest on, the Series 2010 A Bonds shall be paid to the Person in whose name that Obligation (or one or more Predecessor
Obligations) is registered at the close of business on the Record Date applicable to such Interest Payment Date or Redemption Date. Interest on the Series 2010 A Bonds shall be computed on the
basis of a 360-day year of twelve 30-day months. The Series 2010 A Bonds shall be dated the date of authentication. 

        The
Series 2010 A Bonds shall be issued as fully registered global bonds without coupons and in denominations of $1,000 or any integral multiple thereof. The Series 2010 A
Bonds shall be registered in the name of Cede & Co., as nominee of the Securities Depository, pursuant to the Securities Depository's Book-Entry System. When the
Series 2010 A Bonds are held in the Book-Entry System, purchases of beneficial interests in the Series 2010 A Bonds shall be made in book-entry form, without

the Trustee for any tax, fee or other governmental charge required to be paid with respect to such exchange or any transfer of a Series 2010 A Bond. The cost, if
any, of preparing each new Series 2010 A Bond issued upon such exchange or transfer, and any other expenses of the Company or the Trustee incurred in connection therewith, shall be paid by the
person requesting such exchange or transfer. 

        Interest
on the Series 2010 A Bonds shall be payable by check mailed to the registered owners thereof. However, interest on the Series 2010 A Bonds shall be paid to any
owner of $1,000,000 or more in aggregate principal amount of the Series 2010 A Bonds by wire transfer to a wire transfer address within the continental United States upon the written request of
such owner received by the Trustee not less than five days prior to the Record Date. As long as the Series 2010 A Bonds are registered in the name of Cede & Co., as nominee of the
Securities Depository, such payments shall be made directly to the Securities Depository. 

        Section 2.2    Optional Redemption. 

        (a)   The
Company may redeem the Series 2010 A Bonds, in whole or in part, on any date or from time to time prior to their maturity, at its option. The Redemption Price
for the Series 2010 A Bonds will be equal to the greater of: 

          (i)  100%
of the principal amount of the Series 2010 A Bonds being redeemed; and 

         (ii)  the
sum of the present values of the remaining principal and interest payments on the Series 2010 A Bonds being redeemed (excluding interest accrued and unpaid
through the 

4

 

Redemption
Date), discounted on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of (x) the yield
to maturity, determined on the third Business Day prior to the Redemption Date, of a U.S. Treasury security having a life equal to the remaining average life of the maturity of Series 2010 A
Bonds being redeemed and trading in the secondary market at the price closest to par, and (y) 20 basis points, plus in each case accrued and unpaid interest thereon to but excluding the
Redemption Date. 

        (b)   If
there is no U.S. Treasury security having a life equal to the remaining average life of the Series 2010 A Bonds being redeemed, the discount rate will be
calculated using a yield to maturity determined on a straight-line basis (rounding to the nearest calendar month, if necessary) from the average yield to maturity, determined on the third
business day prior to the Redemption Date, of two U.S. Treasury securities having lives most closely corresponding to the remaining average life of the Series 2010 A Bonds being redeemed and
trading in the secondary market at the price closest to par. 

        (c)   Notice
of redemption shall be given by first class mail, postage prepaid, mailed not less than 30 and not more than 60 days prior to the Redemption Date to the
registered address of each Holder of Series 2010 A Bonds being redeemed, except as otherwise required by the procedures of the Securities Depository. Notice of redemption of the
Series 2010 A Bonds shall be given by the Company or at the Company's request, by the Trustee in the name and at the expense of the Company. 

        (d)   If
less than all of the Outstanding Series 2010 A Bonds are to be redeemed, the Series 2010 A Bonds to be redeemed will be selected by the Trustee in any
method it deems fair and appropriate, and the portion of the Series 2010 A Bonds not so redeemed will be in integral multiples of $1,000. 

        (e)   If,
at the time notice of the optional redemption of the Series 2010 A Bonds is given, the Company has not deposited sufficient funds with the Trustee to pay the
full Redemption Price of the Series 2010 A Bonds to be redeemed, the notice of optional redemption will so state and will further state that the Series 2010 A Bonds will remain
Outstanding as though no redemption notice had been given unless the Company provides, or causes to be provided, to the Trustee, by 2:00 p.m. New York City Time on the Redemption Date, funds
sufficient to pay the full Redemption Price of the Series 2010 A Bonds to be redeemed. The failure of the Company to deposit sufficient funds with the Trustee to effect the redemption will not
constitute a payment or other default by the Company under the Indenture and the Company will not be liable to any Holder of those Series 2010 A Bonds as a result of the failed redemption. If
the Company has deposited funds with the Trustee sufficient to pay the full Redemption Price of the Series 2010A Bonds to be redeemed at the time notice of the optional redemption is given,
then the Company is obligated to redeem the Series 2010 A Bonds as provided in that notice. 

        Section 2.3    Form of the Series 2010 A Bonds.    The Series 2010 A
Bonds and the Trustee's authentication certificate to be executed on the Series 2010 A Bonds shall be substantially in the form of  Exhibit B attached hereto, with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted in the
Original Indenture. 

        Section 2.4    Use of Proceeds.    The Company expects the proceeds of this offering of
the Series 2010 A Bonds, net of the initial purchasers' discounts and estimated offering expenses, to be $443,937,500. The Company will use the net proceeds of this offering to finance a
portion of the costs associated with the Company's participation in two additional nuclear units at the Alvin W. Vogtle Plant located in Burke County, Georgia, to redeem outstanding commercial paper
and for general corporate purposes.

        The
Series 2010 A Bonds are equally and ratably secured, to the extent provided in the Indenture, by the Trust Estate, except and excluding the Excepted Property and the

        Reference

B-2

 

of
which the registered owner of this Series 2010 A Bond assents by the acceptance of this Series 2010 A Bond. 

        This
Series 2010 A Bond is transferable, as provided in the Indenture, only upon the registration books of Oglethorpe maintained by the Obligation Registrar, which shall be the
Trustee, kept at its principal office, upon presentation at said office of this Series 2010 A Bond with the written request of the registered owner hereof or his attorney duly authorized in

notice of redemption of the Series 2010 A Bonds or (ii) register the transfer of or exchange of any Series 2010 A Bond so selected for redemption in whole or in part, except the
unredeemed portion of a Series 2010 A Bond being redeemed in part. 

        The
Series 2010 A Bonds are issuable in the form of fully registered global bonds without coupons in the denomination of $1,000 each or any integral multiple thereof. Upon payment
of any required tax or other governmental charge and, subject to such conditions, the Series 2010 A Bonds, upon the surrender thereof at the principal office of the Obligation Registrar, with a
written instrument of transfer
satisfactory to the Obligation Registrar, duly executed by the registered owner or his duly authorized attorney, may, at the option of the registered owner thereof, be exchanged for an equal aggregate
principal amount of Series 2010 A Bonds of the same interest rate and in any other authorized denominations. 

        This
Series 2010 A Bond shall bear interest from, and including, the date hereof to, but excluding, November 1, 2040. Interest shall be payable in arrears on May 1
and November 1 of each year prior to the maturity date of the Series 2010 A Bonds, commencing on May 1, 2011. Interest on this Series 2010 A Bond shall be computed on the
basis of a 360-day year of twelve 30-day months. 

         Optional Redemption:    The Company may redeem the Series 2010 A Bonds, in whole or in part, on any date or from time to time
prior to their
maturity, at its option. The Redemption Price for the Series 2010 A Bonds will be equal to the greater of: 

          (i)  100%
of the principal amount of the Series 2010 A Bonds being redeemed; and 

         (ii)  the
sum of the present values of the remaining principal and interest payments on the Series 2010 A Bonds being redeemed (excluding interest accrued and unpaid
through the Redemption Date), discounted on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at a rate equal to the sum of
(i) the yield to maturity, determined on the third Business Day prior to the Redemption Date, of a U.S. Treasury security having a life equal to the remaining average life of the maturity of
Series 2010 A Bonds being redeemed and trading in the secondary market at the price closest to par, and (ii) 20 basis points, plus in each case accrued and unpaid interest thereon to but
excluding the Redemption Date. 

        If
there is no U.S. Treasury security having a life equal to the remaining average life of the Series 2010 A Bonds being redeemed, the discount rate will be calculated using a
yield to maturity determined on a straight-line basis (rounding to the nearest calendar month, if necessary) from the average yield to maturity, determined on the third Business Day prior
to the Redemption Date, of two U.S. Treasury securities having lives most closely corresponding to the remaining average life of the Series 2010 A Bonds being redeemed and trading in the
secondary market at the price closest to par. 

        If
less than all of the outstanding Series 2010 A Bonds are to be redeemed, the Series 2010 A Bonds to be redeemed will be selected by the Trustee in any method it deems
fair and appropriate, and the portion of the Series 2010 A Bonds not so redeemed will be in integral multiples of $1,000. 

B-3

 

        The
registered owner of this Series 2010 A Bond shall have no right to enforce the provisions of the Indenture, or to institute action to enforce the covenants therein, or to take
any action with respect to any default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture. 

        All
acts, conditions and things required by the Constitution and statutes of the State of Georgia, the governing rules and procedures of Oglethorpe and the Indenture to exist, to have
happened and to have been performed precedent to and in the issuance of this Series 2010 A Bond, do exist, have happened and have been performed. 

        No

official, officer, agent or employee of Oglethorpe in his individual capacity, and no officer of Oglethorpe executing this Series 2010 A Bond shall be liable personally on this
Series 2010 A Bond or be subject to any personal liability or accountability by reason of the issuance of this Series 2010 A Bond. 

        This
