 Section 2.4 Optional Prepayments and Make-Whole Amount. The Company may, at its
option, upon notice as provided below, prepay at any time all, or from time to time any part of, the 2012 Series A Bonds, in an amount not less than 3% of the aggregate principal amount of the 2012 Series A bonds then outstanding in the
case of a partial prepayment, at 100% of the principal amount so prepaid, and the Make-Whole Amount determined for the prepayment date with respect to such principal amount. The Company will give each 2012 Series A Holder written notice of each
optional prepayment under this section 2.4 not less than 30 days and not more than 60 days prior to the date fixed for such prepayment. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of
the 2012 Series A Bonds to be prepaid on such date, the principal amount of each 2012 Series A Bond held by such 2012 Series A Holder to be prepaid (determined in accordance with section 2.5), and the interest to be paid on the
prepayment date with respect to such principal amount being prepaid, and shall be accompanied by an Officer’s Certificate as to the estimated Make-Whole Amount due in connection with such prepayment (calculated as if the date of such notice
were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each 2012 Series A Holder an Officer’s Certificate specifying the calculation of such
Make-Whole Amount as of the specified prepayment date. The Company shall contemporaneously deliver a copy of such notice and Officer’s Certificate to the Trustee. 
 Section 2.5 Allocation of Partial Prepayments. In the case of each partial prepayment of the 2012 Series A Bonds, the principal amount of the 2012 Series A Bonds to be prepaid
shall be allocated among all of the 2012 Series A Bonds at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. 

Section 2.6 Payment of Make-Whole Amount Upon Acceleration. Upon the occurrence of an Event of Default, if the
outstanding principal amount of the 2012 Series A Bonds shall have been declared or otherwise become due and payable immediately 

 

	(1)	The final maturity date of 2012 Series A, Tranche C Bonds due March 15, 2042. 

  
 10 

 
pursuant to and in accordance with the Indenture then, in addition to paying each 2012 Series A Holder the entire unpaid principal amount of its 2012 Series A Bonds and all accrued and
unpaid interest thereon (including, but not limited to, interest accrued thereon at the Default Fate), the Company shall calculate and pay to each 2012 Series A Holder (to the full extent permitted by applicable law) an amount equal to the
Make-Whole Amount determined in respect of such principal amount. The Company acknowledges that each 2012 Series A Holder has the right to maintain its investment in the 2012 Series A Bonds free from repayment by the Company (except as
herein and in the Indenture specifically provided for) and that the provision for payment of a Make-Whole Amount by the Company in the event that the 2012 Series A Bonds are prepaid or are accelerated as a result of an Event of Default, is
intended to provide compensation for the deprivation of such right under such circumstances. 
 Section 2.7
Maturity; Surrender. In the case of each prepayment of 2012 Series A Bonds pursuant to this Article II, the principal amount of each 2012 Series A Bond to be prepaid shall mature and become due and payable on the date fixed for
such prepayment (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount
when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any 2012 Series A Bond paid or prepaid in full shall be surrendered to the Company and
cancelled and shall not be reissued, and no 2012 Series A Bond shall be issued in lieu of any prepaid principal amount of any 2012 Series A Bond. 
 Section 2.8 Purchase of 2012 Series A Bonds. The Company will not, and will not permit any Affiliate to, purchase, redeem, prepay or otherwise acquire, directly or indirectly, any
of the outstanding 2012 Series A Bonds except (a) upon the payment or prepayment of the 2012 Series A Bonds in accordance with the terms of the Indenture and the 2012 Series A Bonds or (b) pursuant to an offer to purchase
made by the Company or an Affiliate pro rata to the Holders of all 2012 Series A Bonds at the time outstanding upon the same terms and conditions. Any such offer shall provide each 2012 Series A Holder with sufficient information to enable
it to make an informed decision with respect to such offer, and shall remain open for at least 30 Business Days. If the Holders of more than 51% of the principal amount of the 2012 Series A Bonds then outstanding accept such offer, the
Company shall promptly notify the remaining 2012 Series A Holders of such fact and the expiration date for the acceptance by 2012 Series A Holders of such offer shall be extended by the number of days necessary to give each such remaining
2012 Series A Holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all 2012 Series A Bonds acquired by it or any Affiliate pursuant to any payment, prepayment or purchase
of 2012 Series A Bonds pursuant to any provision of this Third Supplemental Indenture and no 2012 Series A Bonds may be issued in substitution or exchange for any such 2012 Series A Bonds.

 Section 2.9 Make Whole Amount. 

“Make-Whole Amount” means, with respect to any 2012 Series A Bond, an amount equal to the excess, if any, of the
Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such 2012 Series A Bond over the amount of such Called Principal, provided that the Make-Whole Amount may in no event be less than zero. For the
purposes of determining the Make-Whole Amount with respect to any 2012 Series A Bond, the following terms have the following meanings: 
 “Called Principal” means, with respect to any 2012 Series A Bond, the principal of such 2012 Series A Bond that is to be prepaid pursuant to Section 2.4 or has become or is
declared to be immediately due and payable pursuant to the Indenture, as the context requires. 
 “Discounted
Value” means, with respect to the Called Principal of any 2012 Series A Bond, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the
Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the 2012 Series A Bonds is payable) equal to the
Reinvestment Yield with respect to such Called Principal. 
 “Reinvestment Yield” means, with respect to the
Called Principal of any 2012 Series A Bond, the sum of 0.50% plus the yield to maturity implied by (i) the yields reported as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with
respect to such Called Principal, on the display designated as “Page PX1” (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on the run U.S. Treasury securities
having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date, or (ii) if such yields are not reported as of such time or the yields reported as of such time are not ascertainable (including by way of
interpolation), the Treasury Constant Maturity Series Yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal
Reserve Statistical Release H.15 (or any comparable successor publication) for actively traded U.S. Treasury securities having a constant maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date.

  
 12 

 In the case of each determination under clause (i) or clause (ii), as the case may
be, of the preceding paragraph, such implied yield will be determined, if necessary, by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating
linearly between (1) the applicable actively traded U.S. Treasury security with the maturity closest to and greater than such Remaining Average Life and (2) the applicable actively traded U.S. Treasury security with the maturity closest to
and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the applicable 2012 Series A Bond. 

“Remaining Average Life” means, with respect to any Called Principal, the number of years (calculated to the nearest
one-twelfth year) obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by
(b) the number of years (calculated to the nearest one-twelfth year) that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment. 

“Remaining Scheduled Payments” means, with respect to the Called Principal of any 2012 Series A Bond, all payments
of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date; provided that if such Settlement Date
is not a date on which interest payments are due to be made under the terms of the 2012 Series A Bonds, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date
and required to be paid on such Settlement Date pursuant to Section 2.4 above. 
 “Settlement Date” means,
with respect to the Called Principal of any 2012 Series A Bond, the date on which such Called Principal is to be prepaid pursuant to Section 2.4 or has become or is declared to be immediately due and payable pursuant to the Indenture, as
the context requires. 
 Section 2.10 Use of Proceeds. The Company shall use the proceeds of the loan
evidenced by the 2012 Series A Bonds to repay indebtedness and for general corporate purposes.

 FOR VALUE RECEIVED, the undersigned, CHUGACH ELECTRIC ASSOCIATION, INC. (herein called the
“Company”), an electric cooperative organized and existing under the laws of the State of Alaska, hereby promises to pay to
[                            ], or registered assigns, the principal sum of
[            ] Dollars (or so much thereof as shall not have been prepaid) on
[                    ], with interest computed on the basis of a 360-day year of twelve 30-day months (a) on the unpaid balance hereof at a rate
of [    ]% per annum (plus, upon the occurrence and during the continuation of an Interest Rate Adjustment Event (as hereinafter defined), an additional 2% per annum) from the date hereof, payable semiannually on the 15th
day of each March and September, commencing on September 15, 2012, until the principal hereof shall have become due and payable, and (b) to the extent permitted by law, on any overdue payment (including any overdue prepayment) of
principal, any overdue payment of interest, any overdue payment of any Make-Whole Amount (as defined in the Third Supplemental Indenture referred to 

 
below), payable semiannually as aforesaid (or, at the option of the registered Holder hereof, on demand), at the Default Rate (as defined in the Third Supplemental Indenture referred to below).

 “Interest Rate Adjustment Event” means the occurrence of any of the following: 

(a) the Company defaults in the performance of Section 7.1(a) or (b) or Section 7.2 of the Bond Purchase
Agreement (as defined below); or 
 (b) any representation or warranty made in writing by or on behalf of the
Company or by any officer of the Company in the Indenture or the Bond Purchase Agreement (as defined below) or in any writing furnished in connection with the transactions contemplated by the Third Supplemental Indenture (referred to below) proves
to have been false or incorrect in any material respect on the date as of which made and, with respect to representations and warranties made after the date hereof, for which accurate information has not since been provided in writing to the Holder
of this Bond. 
 Subject to Section 11 of the Bond Purchase Agreement (defined below), payments of principal of, interest
on, and any Make-Whole Amount with respect to this Bond are to be made in lawful money of the United States of America in accordance with the terms of the Indenture. 
 This Bond is one of the 2012 Series A, Tranche [A][B][C] Bonds due [March 15, [2032][2042]] (herein called the “Bonds”) issued pursuant to the Third Supplemental Indenture,
dated as of January 5, 2012 (as from time to time amended, the “Third Supplemental Indenture”), between the Company and the Trustee named therein which amends and supplements the Second Amended and Restated Indenture of Trust,
dated as of January 20, 2011 (as amended and supplemented from time to time, the “Indenture”) and is entitled to the benefits thereof and the Bond Purchase Agreement dated January 11, 2012, between the Company and the
purchasers listed in Schedule A thereto (the “Bond Purchase Agreement”). Each Holder of this Bond will be deemed, by its acceptance hereof, to have (i) agreed to the confidentiality provisions set forth in Section 18 of
the Bond Purchase Agreement and (ii) made the representations set forth in Section 6 of the Bond Purchase Agreement. Unless otherwise indicated, capitalized terms used in this Bond shall have the respective meanings ascribed to such terms
in the Third Supplemental Indenture. 
 This Bond shall be registered in the name of the Holder hereof. This Bond is
transferable, as provided in the Indenture, only upon the registration books of the Company 

  
 B-2

 
maintained by the Obligation Registrar, which shall be the Trustee, kept at its principal office, upon presentation at said office of this Bond with the written request of the registered owner
hereof or his attorney duly authorized in writing, and a written instrument of transfer satisfactory to the Obligation Registrar duly executed by the registered owner or his duly authorized attorney. 

The Bonds shall be issued as fully registered Bonds without coupons and in minimum denominations of $1.00 and any integral multiple of
$1.00 in excess thereof. The Trustee may impose a charge sufficient to reimburse the Company or the Trustee for any tax, fee or other governmental charge required to be paid with respect to such exchange or any transfer of a Bond. The cost, if any,
of preparing each new 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 in accordance with Section 3.7 of the Indenture. 

The Company will make the required prepayments of principal on this Bond on the dates and in the amount specified in the Third
Supplemental Indenture. This Bond is also subject to optional prepayment, in whole or from time to time in part, at the times and on the terms specified in Third Supplemental Indenture, but not otherwise. 

If an Event of Default under the Indenture occurs and is continuing, the principal of this Bond may be declared or otherwise become due
and payable in the manner, at the price (including any applicable Make-Whole Amount) and with the effect provided in the Indenture. In the event that the principal of this Bond shall have been declared or otherwise become due and payable as
described in the preceding sentence, then, in addition to paying the Holder hereof the entire unpaid principal amount of this Bond and all accrued and unpaid interest hereon (including, but not limited to, interest accrued hereon at the Default
Rate), the Company shall pay to the Holder hereof (to the full extent permitted by applicable law) an amount equal to the Make-Whole Amount determined in respect of such principal amount. 

The Holder of this 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 and the Bond Purchase Agreement. 

All acts and proceedings required by law and by the Articles of Incorporation and Bylaws of the Company necessary to make the 2012
Series A Bonds issued under the Indenture, when executed by the Company, authenticated and delivered by the Trustee and duly issued, the valid, binding and legal obligations of the Company, in accordance with its terms, have been done and
taken. 

  
 B-3

 It is the intention of the Holder to comply with the usury laws of the State of Alaska and
of the United States of America. This Bond is hereby expressly limited such that in no contingency or event whatsoever, whether by reason of acceleration, prepayment, or otherwise, shall the amount of interest contracted for, charged or received by
the Holder for the use, forbearance, or detention of the principal indebtedness or interest hereof, which remains unpaid from time to time, exceed the highest maximum rate permitted by applicable law. If fulfillment of any provisions hereof, at the
time of performance of such provisions shall be due, shall involve transcending the valid limits prescribed by applicable law, then, ipso facto, the obligation to be fulfilled shall be reduced to the maximum rate allowed by applicable law. If any
Holder receives as interest an amount which will exceed the maximum rate allowed by applicable law, such amount shall be applied to the reduction of the principal amount owing hereunder or on account of any other principal indebtedness owed to
Holder and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal hereof and such other indebtedness, such excess shall be refunded. To the extent not prohibited by applicable law, determination of the
maximum rate allowed by applicable law shall at all times be made by amortizing, prorating, allocating and spreading in equal parts during the full term of this Bond, all interest at any time contracted for, charged or received from the Company in
connection with this Bond, so that the actual rate of interest on account of such indebtedness is uniform throughout the term of this Bond. The terms of this paragraph shall control and supersede any other provisions of this Bond. 

This Bond shall be construed in accordance with and governed by the law of the State of Alaska. 

No covenant or agreement contained in this Bond, the Indenture or the Third Supplemental Indenture shall be deemed to be a covenant or
agreement of any official, officer, agent or employee of the Company in his individual capacity, and no officer of the Company executing this Bond shall be liable personally on this Bond or be subject to any personal liability or accountability by
reason of the issuance of this Bond. 
 This Bond shall not be entitled to any benefit under the Indenture or be valid until
this Bond shall have been authenticated by the execution by the Trustee, or its successor as Trustee, of the Certificate of Authentication inscribed hereon.
