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).

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

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 B Bonds due March 15, 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 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

 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. 
 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.

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

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.

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

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.

 It is the intention of the Holder to comply with the usury laws of the State of Alaska and of the United States of

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.

principal sum of ONE MILLION FIVE HUNDRED THOUSAND DOLLARS (or so much thereof as shall not have been prepaid) on March 15, 2042, 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 4.41% 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 B Bonds due March 15, 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 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.

  
 -2-

 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. 
 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. 

  
 -3-

 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.

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.

taken. 
 It is the intention of the Holder to comply with the usury laws of the State of Alaska and of the United States of

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.

Alaska.

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.

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.

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.

 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

taken. 
 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.

of this Bond. 
 Subject to Section 11 of the Bond Purchase Agreement (defined below), payments of principal of, interest

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

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.

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

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 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

 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. 
 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.

 (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 C Bonds due March 15, 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 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. 
 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.
