All capitalized terms used and not otherwise defined in this Tenth Supplemental Indenture shall have the meanings assigned to those terms in the Indenture, except where the context clearly indicates otherwise. U.S. BANK TRUST NATIONAL ASSOCIATION, a national banking association, currently acts as the Trustee under the Indenture. Pursuant to the Indenture, the Company did grant, bargain, sell, alien, remise, release, convey, assign, transfer, mortgage, hypothecate, pledge, set over and confirm to the Trustee all rights, privileges and franchises of the Company of every kind and description, real, personal or mixed, tangible and intangible, whether then owned or thereafter acquired by the Company, except any Excepted Property (as defined in the Indenture), and granted a security interest therein for the purposes therein expressed. The Indenture secures payment of the principal of (and premium, if any) and interest on the Outstanding Secured Bonds (as defined in the Indenture) and the performance of the covenants contained in such Outstanding Secured Bonds and the Indenture. The purpose of the First, Second, Fourth, Sixth, Eighth and Ninth Supplemental Indentures was to confirm the Company's intention that certain real property (described in the respective Supplemental Indentures) acquired by the Company after the date of the Original Indenture be subjected to the lien of the Indenture, and to confirm the substitution of Seattle-First National Bank (successor by merger to the original Trustee, Security Pacific Bank Washington, N.A.) as Trustee under the Indenture. The purposes of the Third and Seventh Supplemental Indentures were to establish and modify, respectively, a series of bonds designated First Mortgage Bonds, CoBank Series, to be issued to CoBank, ACB. The purpose of the Fifth Supplemental Indenture was to establish a series of bonds designated First Mortgage Bonds, Series CFC, to be issued to the National Rural Utilities Cooperative Finance Corporation. Because U.S. Bank Trust National Association, a national banking association (formerly known as First Trust National Association), has acquired the trust business of Bank of America NW, N.A. (formerly known as Seattle-First National Bank), U.S. Bank Trust National Association has succeeded to the interest of the Trustee under the Indenture. 3 The purposes of this Tenth Supplemental Indenture are to (i) provide for the creation of two new series of Bonds, designate the series to be created and specify the form and provisions of the Bonds of each such new series, and (ii) amend and restate the Indenture in its entirety, effective as of and after the Release Date (as defined below), such that, from and after the Release Date, (A) all Outstanding Secured Bonds issued on or after the date of this Tenth Supplemental Indenture shall constitute Obligations as defined in, and be entitled to the benefits of, the Amended and Restated Indenture (as defined below), and (B) the lien and security interests arising under the Indenture on the Trust Estate shall terminate and the entire Trust Estate (as defined in the Indenture) shall be reconveyed and re-assigned to the Company. A. Amendments to Original Indenture. The Original Indenture is hereby further amended as follows: (1) In Article One, there is added a new definition, as follows: "Release Date" means the earliest date on which there ceases to be Outstanding each and every Bond issued prior to April 1, 2001, other than any Bond whose Holder shall have agreed in writing that the Release Date may occur while such Bond remains Outstanding. (2) With respect to Bonds issued on or after the date of this Tenth Supplemental Indenture, the words "First Mortgage Bond" appearing in the title of the Bonds at the top of page 31 in Section 2.02 (Form of Face of Bond) of the Original Indenture are deleted and the words "New Bond" are substituted therefor. (3) With respect to Bonds issued on or after the date of this Tenth Supplemental Indenture, Section 2.03 (Form of Reverse of Bond) of the Original Indenture is amended as follows: (a) The first sentence of the first paragraph of Section 2.03 on pages 32-33 of the Original Indenture is deleted in its entirety and the following sentences are substituted therefor: This is one of the Bonds referred to in and secured by the Indenture of Trust dated as of September 15, 1991, by and between Chugach Electric Association, Inc. and Security Pacific Bank Washington, N.A., as trustee, as the same may be amended and effective from time to time prior to the Release Date (as defined therein) (the "Pre-Release Indenture"), under which the undersigned now acts as trustee (the "Trustee," which term includes any successor trustee 4 under the Indenture). From and after the Release Date (as defined in the Tenth Supplemental Indenture of Trust to the Pre-Release Indenture), this shall constitute one of the unsecured Obligations referred to in and entitled to the benefits of that Amended and Restated Indenture dated April 1, 2001, between Chugach Electric Association, Inc. and U.S. Bank Trust National Association, the form of which is attached as Exhibit A to such Tenth Supplemental Indenture (the "Amended and Restated Indenture"), which Amended and Restated Indenture amends and supersedes the Pre-Release Indenture in its entirety from and after the Release Date. The Pre-Release Indenture, including all indentures supplemental thereto and effective prior to the Release Date, contains a statement of the description of the properties thereby mortgaged, pledged and assigned, the nature and extent of the security and the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Bonds and of the terms upon which the Bonds are, and are to be, authenticated and delivered, in each case prior to the Release Date. The Amended and Restated Indenture, including all indentures supplemental thereto, contains a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Obligations and of the terms upon which the Obligations are, and are to be, authenticated and delivered from and after the Release Date. From and after the Release Date, the term "Bond" as used in this instrument shall be construed to mean "Obligation" as that term is used in the Amended and Restated Indenture and all indentures supplemental thereto. The term "Indenture" as used herein means the Pre-Release Indenture prior to the Release Date and the Amended and Restated Indenture from and after the Release Date. (b) In the first full paragraph on page 37 of the Original Indenture: (i) The phrase "Section 13.02 of the Indenture" is deleted and the phrase "Section 13.02 of the Pre-Release Indenture (prior to the Release Date) or Section 10.2 of the Amended and Restated Indenture (on and after the Release Date)" is substituted therefor. (ii) The phrase "Article Nine" is deleted and the phrase "Article Nine of the Pre-Release Indenture (prior to the Release Date) or Article 6 of the Amended and Restated Indenture (on and after the Release Date)" is substituted therefor. 5 (c) In the first paragraph on page 38 of the Original Indenture, "Section 34.22.010" is deleted and "Section 34.20.160" is substituted therefor. (4) Section 2.04 (Form of Trustee's Certificate of Authentication) of the Original Indenture is amended to provide that the form of Trustee's Certificate of Authentication for all Bonds issued after the date of this Tenth Supplemental Indenture and prior to the Release Date is as follows: This is one of the Bonds referred to in and secured by the Indenture of Trust dated as of September 15, 1991, by and between Chugach Electric Association, Inc. and Security Pacific Bank Washington, N.A., as the same may be amended and effective from time to time prior to the Release Date (the "Pre-Release Indenture"), under which the undersigned now acts as Trustee. From and after the Release Date (as defined in the Tenth Supplemental Indenture of Trust to the Pre-Release Indenture), this shall constitute one of the unsecured Obligations referred to in and entitled to the benefits of that Amended and Restated Indenture dated April 1, 2001, between Chugach Electric Association, Inc. and U.S. Bank Trust National Association, the form of which is attached as Exhibit A to such Tenth Supplemental Indenture (the "Amended and Restated Indenture"), which Amended and Restated Indenture amends and supersedes the Pre-Release Indenture in its entirety from and after the Release Date. ______________________________ as Trustee By: ______________________________ Authorized Signatory (5) Section 3.01 (General Title) of the Original Indenture is amended to provide that the general title of the Bonds of all series of Bonds issued after the date of this Tenth Supplemental Indenture and prior to the Release Date shall be "NEW BONDS." 6 B. New Bonds, 2001 Series A. There is hereby established under the Indenture, as further amended by this Tenth Supplemental Indenture, a new series of Bonds, as follows: (1) The new series of Bonds is entitled "New Bonds, 2001 Series A." (2) The New Bonds, 2001 Series A shall be governed by the provisions of Appendix 1 attached to this Tenth Supplemental Indenture. C. New Bonds, CoBank Series B. There is hereby established under the Indenture, as modified by this Tenth Supplemental Indenture, a new series of Bonds, as follows: (1) The new series of Bonds is entitled "New Bonds, CoBank Series B." (2) The New Bonds, CoBank Series B shall be governed by the provisions of Appendix 2 attached to this Tenth Supplemental Indenture. D. Amended and Restated Indenture. Effective from and after the Release Date, (i) all covenants, terms, conditions and other provisions of the Indenture shall be amended and superseded in their entirety by the covenants, terms, conditions and other provisions of the Amended and Restated Indenture dated as of April 1, 2001, a copy of which is attached as Exhibit A to this Tenth Supplemental Indenture, and (ii) any lien or security interest arising under the Indenture shall automatically and without further action terminate, and (iii) the Trustee shall forthwith take all steps (including but not limited to execution, delivery, recording and filing of satisfactions of mortgage or Uniform Commercial Code termination statements) the Company deems reasonably necessary or desirable to confirm or give notice of the termination and release of any lien or security interest arising under the Indenture and to evidence the reconveyance, re--assignment, and transfer to the Company of all right, title and interest of the Trustee in and to the Trust Estate (including but not limited to all Trust Moneys and Pledged Securities). E. Ratification. Except as expressly amended by this Tenth Supplemental Indenture, the Indenture is in all respects ratified and confirmed and all the terms, provisions and conditions of the Indenture shall remain in full force and effect, and this Tenth Supplemental Indenture shall be deemed to be a part of the Indenture. F. Counterparts. This Tenth Supplemental Indenture may be executed in any number of counterparts, each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument. G. Execution Date. Although this Tenth Supplemental Indenture is dated for convenience and for the purpose of reference as of the date set forth in the first paragraph hereof, the actual date or dates of execution by the Company and by the Trustee are as indicated by their respective acknowledgments hereto annexed. 7 CHUGACH ELECTRIC ASSOCIATION, INC., an Alaska electric cooperative By /s/ Eugene N.

A. General Provisions and Definitions All Capitalized terms used but not otherwise defined herein shall have the meanings assigned to those terms in the Indenture, except in cases where the context clearly indicates otherwise. B. New Bonds of 2001 Series A and Certain Provisions Relating Thereto (1) Specific Title, Terms and Forms. (a) The new series of Bonds is entitled "New Bonds, 2001 Series A" (herein called the "2001 Series A Bonds"). The forms thereof shall be substantially as set forth in Article Two with such insertions, omissions, substitutions and variations as may be determined by the Officers executing the same as evidenced by their execution thereof to reflect the applicable terms of the 2001 Series A Bonds established by this Article. (b) The aggregate principal amount of the 2001 Series A Bonds which may be authenticated and delivered and Outstanding is limited to One Hundred Fifty Million Dollars ($150,000,000). The 2001 Series A Bonds shall be issued in denominations of $1,000 or any multiple thereof. Interest shall be computed on the basis of a 360-day year of twelve 30-day months. (c) The 2001 Series A Bonds shall bear interest from their date payable on September 15, 2001, and semiannually thereafter on the fifteenth (15th) day of March and the fifteenth (15th) day of September of each year at the rate of six and 55/100 percent (6.55%) per annum and shall mature on March 15, 2011. (d) The principal of, and interest on, the 2001 Series A Bonds shall be payable at the office or agency of the Trustee at 180 East Fifth Street, 3rd Floor, St. Paul, MN 55101. Such location is herein called a Place of Payment. i (e) The Regular Record Date for the payment of the interest on the 2001 Series A Bonds payable, and punctually paid or duly provided for, on any Interest Payment Date shall be the last day (whether or not a business day) of the calendar month next preceding such Interest Payment Date. (2) Exchangeability. When the 2001 Series A Bonds are held in a Book-Entry System, the delivery of 2001 Series A Bonds, exchanges, transfers and assignment of the 2001 Series A Bonds and issuance of the 2001 Series A Bonds shall be determined by the provisions of the DTC Letter of Representation executed by the Company in connection with such series (as the same may amended from time to time). Subject to Section 3.07 of the Indenture, all 2001 Series A Bonds not held in the Book-Entry System shall be fully interchangeable, and, upon surrender at the office or agency of the Trustee in a Place of Payment therefor, shall be exchangeable for other 2001 Series A Bonds of the same maturity but of a different authorized denomination or denominations, as requested by the Holder surrendering the same. The Company will execute, and the Trustee shall authenticate and deliver, 2001 Series A Bonds whenever the same are required for any such exchange. (3) No Redemption. The 2001 Series A Bonds are not redeemable at any time prior to maturity. (4) Book-Entry System, Certificates, Registration and Payment. (a) The 2001 Series A Bonds initially shall be held in a Book-Entry System and shall (except to the extent otherwise required by the DTC Letter of Representation with respect to the 2001 Series A Bonds) be evidenced by one certificate for each maturity, in an amount equal to the aggregate principal amount of such maturity. (b) The principal of, premium, if any, and interest on the 2001 Series A Bonds shall be payable in lawful money of the United States of America. While the 2001 Series A Bonds are held in the Book-Entry System, payment of the principal of, premium, if any, and interest on the 2001 Series A Bonds shall be made by wire transfer of Federal funds or equivalent same-day funds, or in such other manner as permitted by the DTC Letter of Representation executed by the Company in connection with such series (as the same may be amended from time to time), to the account of Cede & Co. In the event the 2001 Series A Bonds are no ii longer held in the Book-Entry System, interest on the 2001 Series A Bonds shall be payable on each Interest Payment Date by check payable to the Holder (except that if so instructed in writing by a Holder of $1,000,000 or more of the 2001 Series A Bonds, such payments shall be made by wire transfer of Federal Reserve funds on the Interest Payment Date), mailed to the Holder at his or her address as it appears on the Bond Register on the last day of the calendar month prior to the Interest Payment Date, or in such other manner as such Holder and the Trustee may determine. Except as may be provided in the DTC Letter of Representation with respect to 2001 Series A Bonds, payment of principal (other than through operation of a sinking fund, if any) shall be made only upon presentation and surrender of each 2001 Series A Bond, as the same becomes due, at the office from which the Trustee performs the payment function for 2001 Series A Bonds. (c) The Trustee shall act as Bond Registrar and shall maintain registration books for the registration and the registration of transfer of the 2001 Series A Bonds. (d) So long as the 2001 Series A Bonds are held in the Book-Entry System, the registered Holder of all of the 2001 Series A Bonds shall be DTC, and the 2001 Series A Bonds shall be registered in the name of Cede & Co., as nominee for DTC pursuant to the DTC Letter of Representation with respect to 2001 Series A Bonds, as amended from time to time, and the provisions of such Letter of Representation shall be incorporated herein by this reference. (e) Upon initial issuance, the ownership of the 2001 Series A Bonds shall be registered by the Trustee on the Bond Register in the name of Cede & Co., as nominee of DTC. The Trustee and the Company may treat DTC (or its nominee) as the sole and exclusive registered Holder of the 2001 Series A Bonds registered in its name for the purposes of payment of the principal of or interest on the 2001 Series A Bonds, giving notice as required under this Indenture, registering the transfer of 2001 Series A Bonds, obtaining any consent or other action to be taken by the Holders and for all other purposes whatsoever; and neither the Trustee nor the Company shall be affected by any notice to the contrary. Neither the Trustee nor the Company shall have any responsibility or obligation to any person claiming a beneficial ownership interest in the 2001 Series A Bonds under or through DTC or any DTC Participant, or any other person which is not shown on the Bond Register as being a registered Holder, with respect to the accuracy of any records maintained by DTC or any DTC Participant; the payment by DTC or any DTC Participant of any amount in respect of the principal of or interest on the 2001 Series A Bonds; any notice or direction which is permitted or required to be given to or received from Holders under this Indenture; or any consent given or other action taken by DTC as Holder; nor shall any DTC Participant or any such Person be deemed to be a third party beneficiary of any Holders' rights under this Indenture. The Trustee shall pay from moneys available hereunder all principal of and premium, iii if any, and interest on the 2001 Series A Bonds only to or upon the order of DTC or its designee, and all such payments shall be valid and effective to fully satisfy and discharge the Company's obligations with respect to the principal of and premium, if any, and interest on the 2001 Series A Bonds to the extent of the sum or sums so paid. So long as the 2001 Series A Bonds are held in the Book-Entry System, no person other than DTC shall receive an authenticated Bond for each separate stated maturity evidencing the obligation of the Company to make payments of principal of and premium, if any, and interest pursuant to this Indenture. Upon delivery by DTC to the Trustee of DTC's written notice to the effect that DTC has determined to substitute a new nominee in place of Cede & Co., and subject to the provisions of this Indenture with respect to transfers of 2001 Series A Bonds, the term "Cede & Co." in this Indenture shall refer to such new nominee of DTC. (5) Availability of Bond Certificates. At any time it determines that it is in the best interests of the Holders, the Company may notify DTC and the Trustee, whereupon DTC will, if consistent with DTC's then-current policies, notify the DTC Participants, of the availability through DTC of 2001 Series A Bond certificates. In such event, the Company shall prepare and execute and the Trustee shall issue, transfer and exchange, at the expense of the Company, 2001 Series A Bond certificates as requested in writing by DTC in appropriate amounts. DTC may determine to discontinue providing its services with respect to the 2001 Series A Bonds at any time by giving written notice to the Company and the Trustee and discharging its responsibilities with respect thereto under applicable law. If DTC resigns as securities depository for the 2001 Series A Bonds, 2001 Series A Bond certificates shall be delivered pursuant to this Section. Under such circumstances (if there is no successor securities depository), the Company and the Trustee shall be obligated to deliver 2001 Series A Bonds as described in this Indenture, provided that the expense in connection therewith shall be paid by the Company. In the event that certificates for 2001 Series A Bonds are issued, the provisions of this Indenture shall apply to, among other things, the transfer and exchange of such certificates and the method of payment of principal of, premium, if any, and interest on such 2001 Series A Bonds. Whenever DTC requests the Company to do so, the Company will cooperate with DTC in taking appropriate action after written notice (a) to make available one or more separate certificates evidencing the 2001 Series A Bonds to any DTC Participant having 2001 Series A Bonds credited to its DTC account, or (B) to arrange for another securities depository to maintain custody of certificates evidencing the 2001 Series A Bonds. iv (6) Use of Proceeds. The Company shall use the proceeds from the sale of the 2001 Series A Bonds: (a) to pay amounts owing under existing lines of credit; (b) to redeem any Outstanding Bonds; and (c) for such other purposes as the Company may determine. (7) Credit Enhancer. MBIA Insurance Corporation ("MBIA") is a Credit Enhancer with respect to the 2001 Series A Bonds. Any notices given to MBIA Insurance Corporation pursuant to the Indenture or otherwise in connection with the 2001 Series A Bonds shall be given to MBIA Insurance Corporation, 113 King Street, Armonk, NY 10504, Attn: Insured Portfolio Management.
