Standing on September 30, 1945), including any amount paid in excess of the principal amount or par or stated value of securities redeemed or retired and, in the event that such redemption or retirement is effected with the proceeds of sale of other securities of the Company, interest or dividends on the securities redeemed or retired from the date on which the funds required for such redemption or retirement are deposited in trust for such purpose to the date or redemption or retirement; (c) any tax charges or credits in connection with the matters referred to in (a) and (b) or other capital assets, or taxes on or in respect of any such profit; or (e) any earned surplus adjustment (including tax adjustments) applicable to any period prior to October 1, 1945.

The term "operating revenues of the Company", as used in the next preceding paragraph, shall mean and include all operating revenues derived by the company from the operation of its plants and properties remaining after deducting therefrom an amount equal to the aggregate cost to the Company of electricity, gas (natural, artificial and mixed), steam or water purchased and rentals paid for the use of property owned by others and leased to or operated by the Company and the maintenance of which and depreciation on which are borne by the owners.

Section 3. Promptly after the execution and delivery of this Thirty-Second Supplemental Indenture, the Company will take such action with respect to the recording, filing, re-recording and re-filng of the First Mortgage as amended and this Thirty –Second Supplemental Indenture as may be necessary to make effective the lien intended to be created hereby, and will furnish to the trustee an opinion of counsel selected by the Company and satisfactory to the Trustee (who may be of counsel to the company) either (a) stating that in the opinion of such counsel such action has been taken with respect to the recording, filing, re-recording and re-filing of the First Mortgage as amended and this Thirty-Second Supplemental Indenture as to make effective the lien intended to be created thereby, and reciting the details of such action, (b) stating that in the opinion of such counsel no such action is necessary to make such lien effective.

SECTION 4. notwithstanding any other provision of the First Mortgage, the Company will give appropriate directions to the Trustee with respect to the application of any cash balance at any time held in the Maintenance and Replacement Fund provided for in Section 5 of Article Eight of the First Mortgage as amended so that there shall not be applied prior to November 1, 1998 to the redemption of the New Bonds any portion of such balance. Nothing contained herein shall limit the right of the Company to deposit New Bonds with the Trustee in satisfaction (to the extent of the principal amount of such Bonds so deposited) of the Company’s obligation to make a deposit under said Section 5 of Article Eight.

ARTICLE FIVE

MISCELLANEOUS

SECTION 1. The New Bonds may be authenticated and delivered by the Trustee and issued by the Company in advance of the recording or filing of this Thirty-Second Supplemental Indenture.

SECTION 3. The terms defined in Article One of the First Mortgage as heretofore and hereby amended, when used in this Thirty-Second Supplemental Indenture, shall, respectively, have the meanings set forth in said Article One.

No New Bonds shall be deemed to be outstanding within the meaning of the phrase "so long as any of the New Bonds shall be outstanding" as used in this Thirty-Second Supplemental Indenture, if the Company shall have exercised its option to redeem all the New Bonds then remaining outstanding and shall have deposited with the Trustee the proper redemption price thereof, to be held by the Trustee in trust for the holders of such Bonds, and provided that notice of such redemption shall have been published as hereinbefore provided or provision, satisfactory to the Trustee, for such publication shall have been made, and provided further that provision shall have been made prohibiting any further issue of New Bonds after such deposit of the redemption price of the New Bonds then outstanding.

AMENDMENTS TO FIRST MORTGAGE AS AMENDED TO BECOME EFFECTIVE AT A LATER DATE OR DATES.

SECTION 1. Each of the amendments provided for by the following Sections 2, 3, 4, 5 and 6 of this Article Three shall become effective on the earliest date on which either (a) there shall not be any Bonds outstanding of Series Due 1982, Series Due 1984 or Series Due 1993, or (b) there shall have been executed and delivered a supplemental indenture or indentures embodying said amendment (either alone or with other amendments) consented to by the holders of seventy-five per centum (75%) in aggregate principal amount of the Bonds at the time outstanding of the series of which Bonds are then outstanding, all in conformity with the provisions of Article EIGHTEEN of the First Mortgage as amended; provided that no consent of the holders of the Bonds of Series Due 1997 shall be required to effect said amendments.

SECTION 2. Effective on a date fixed as provided in Section 1 of this Article Three, the following Clauses in the Granting Clauses of the First Mortgage and of each Supplemental Indenture which has Granting Clauses similarly entitled, “Other Real Estate and Appurtenances” and “Property Hereafter to Become Subject to The Lien of This Indenture” are hereby amended as follows:

(a)

The final phrase of the last paragraph of the Clause entitled “Other Real Estate and Appurtenances” which heretofore provided as follows:

“or (2) in any case, any bonds, notes, evidences of indebtedness, shares of stock or other securities, except such as may be specifically subjected to the lien hereof.”

is amended to read as follows:

“ (2) in any case, to any cars, trucks or other vehicles of any nature for the transportation of personnel, materials or equipment by any means which may have been acquired after the effective date of the amendment to this Clause made by or pursuant to the provisions of the Eleventh Supplemental Indenture, or to any bonds, notes, evidences of indebtedness, shares of stock or other securities, except such as may be specifically subjected to the lien hereof.”

(b)

The final phrase of paragraph A of the Clause entitled “Property Hereafter To Become Subject To The Lien of This Indenture” which heretofore provided as follows:

“or (2) in any case, any bonds, notes, evidences of indebtedness, shares of stock or other securities, except such as may be specifically subject to the lien hereof.”

is amended to read as follows:

“or (2) in any case, any cars, trucks or other vehicles of any nature for the transportation of personnel, materials or equipment by any means, or any bonds, notes, evidences of indebtedness, shares of stock or other securities, except such as may be specifically subject to the lien hereof.”

(c)

Paragraph B of the Clause entitled “Property Hereafter To Become Subject To The Lien of This Indenture” is amended to read as follows:

“B. Any and all property of every name and name and nature, including shares of stock, bonds, other securities or obligations and cars, trucks or other vehicles for the transportation of personnel, materials or equipment by any means, which from time to time after the execution of this Indenture, by delivery or by writing of any kind for the purposes hereof, shall have been conveyed, mortgaged, pledged, assigned or transferred by, or by anyone on behalf of, the Company to the Trustee, which is hereby authorized to receive any property at any and all times, as and for additional security, and also when and as hereinafter provided as and for substituted security, for the payment of the Bonds to be issued hereunder, and to hold and apply any and all such property subject to the terms hereof.”

On that date the obligation of the Company to make payments to the Trustee as a Maintenance and Replacement Fund shall be terminated and all property which shall have theretofore become funded property by being used as a deduction under Section 5 of Article Eight of the First Mortgage as amended shall no longer be funded property except an amount of such funded property equal to the amount of retirements, as defined in Section 4 of Article One of the First Mortgage. In order to effect his result and to change the definition of funded property to include property additions equal to retirements rather than equal to deductions under the Maintenance and Replacement Fund, the following amendments shall become effective on a date fixed as provided in Section 1 of this Article Three:

(a)

Section 5 of Article Eight of the First Mortgage as amended is hereby deleted;

(b)

Subparagraph (7) of Section 5 of Article One of the First Mortgage as amended is hereby amended so as to read:

The cost of any such property additions shall be deemed to be the sum of (1) any cash forming a part of such cost, (2) an amount equivalent to the fair market value in cash of any securities issued or delivered in payment therefore or for the acquisition thereof as of the date of such issue or deliver, and (3) the principal amount of any prior xxxx xxxxx outstanding against such property additions at the time of their acquisition unless the engineer’s certificate, hereinafter in subdivision (3) of Section 6 of this Article Five provided for, shall show that other property additions subject to the lien securing such prior xxxx xxxxx are then funded property as defined in Section 5 of Article One. The fair value to the Company of any such property additions shall be deemed to be the fair value thereof to the company as of the time when such fair value is being determined, such fair value to be determined as if

such property additions were free of prior liens, if any. The amount of funded property, the amount of the cost of any property additions and the then fair value thereof to the Company and the amount of retirements shall be determined for the purpose of this Section by the appropriate certificates provided for in Section 6 of this Article Five.”

(d)

Subparagraph (c) of subdivision (3) of Section 6 of Article Five is hereby amended to read as follows:

“(c) stating that such property additions are desirable for use in the proper conduct of the Company’s business, that such property additions do not consist in whole or in part of funded property as defined in Section 5 of Article One and that funded property includes, as of the date of the certificate, property additions having a cost to the Company equal to the dollar amount stated in said certificate of retirements made by the Company as defined in Section 4 of Article One to a date not more than 30 days prior to the date of the certificate.”

(e)

Subdivision (9) of Section 6 of Article Five is hereby deleted.

Effective on a date fixed as provided in Section 1 of this Article Three, the Company and the Trustee shall enter into a supplemental indenture which shall by amendment delete such references, adjust such enumeration of sections and paragraphs and make such changes in the First Mortgage as amended necessary to make it consistent with the amendments provided for in this Section 3.

SECTION 4. Effective on a date fixed as provided in Section 1 of this Article Three, Section 7 of Article Eight of the First Mortgage as amended is hereby amended by amending clause (a) of the first sentence thereof to read as follows:

“…(a) by reputable fire insurance companies, any loss to be made payable to the Trustee, as its interest may appear, or to the trustee or other holder of any mortgage or other lien constituting a prior lien or a lien prior hereto, if required by the terms thereof, except any loss as to materials and supplies and except any loss less than one million dollars ($1,000,000),…”

Section 5. Effective on a date fixed as provided in Section 1 of this Article Three, Section 3 of Article Eleven of the First Mortgage as amended is hereby amended by amending the first sentence of the third full paragraph of said Section to read as follows:

“In case the release of property is based upon property additions, the Trustee shall also be furnished with such certificates and opinions with respect to such property additions and such instruments and other papers as would be necessary to entitle the Company under the provisions of Section 6 of Article Five hereof to the authentication and delivery of Bonds upon the basis of such property additions, exclusive of the resolution, net earnings certificate and Treasurer’s certificate required by subdivisions (1), (6) and (9) of said Section 6 and such parts of the opinion described in subdivision (7) of said Section 6 as related solely to the authorization of the issuance of Bonds of the Company by governmental authorities and by the Company.”

Section 6. Effective on date fixed as provided in Section 1 of this Article Three, Section 5 of Article Eleven of the First Mortgage as amended is hereby amended by amending that part of the first sentence of the second paragraph thereof which precedes clause (b) to read as follows:

“Such moneys shall from time to time be paid out or used or applied by the Trustee as aforesaid upon the written order of the Company, signed by its President or a Vice-President, and (a) with respect to any payment under subdivision (1) above, upon receipt by the Trustee of such certificates, opinions, instruments and other papers with respect to such property additions as would be necessary under the provisions of Section 6 of Article Five hereof to entitle the Company to the authentication and delivery of Bonds upon the basis thereof, exclusive of the resolution, net earnings certificate and Treasurer’s certificate required by subdivisions (1), (6) and (9) of said Section 6 and of such parts of the opinion described in subdivision (7) of said Section 6 as relate solely to the authorization of the issuance of Bonds of the Company by governmental authorities and by the Company; or …”

Section 7. Any supplemental indentures may contain such other provisions as may be necessary or appropriate to carry into effect the purposes of the amendments provided for by this Article Three or as may be otherwise appropriate and permissible under the provisions of Article Eighteen of the First Mortgage to accomplish the purposes of said amendments. To the extent permitted by Article Eighteen of the First Mortgage as amended, any supplemental indenture may terminate or modify specified obligations of the Company to the holders of the bonds of a particular series and such amendment will only require the consent by holders of seventy-five per centum (75%) in aggregate principal amount of the bonds outstanding of said series. Said amendments may effect the purposes herein contemplated either by adding provisions to, or eliminating provisions from, the First Mortgage as amended, or by both adding and eliminating provisions, or may accomplish said purposes in any other appropriate manner.
