IN TRUST NEVERTHELESS, for the same purposes and upon the same terms, trusts and conditions and subject to and with the same provisos and covenants as are set forth in the Mortgage, this Eleventh Supplemental Indenture being supplemental to the Mortgage; AND IT IS HEREBY COVENANTED by the Company that all the terms, conditions, provisos, covenants and provisions contained in the Mortgage shall affect and apply to the property hereinbefore described and conveyed, and to the estates, rights, obligations and duties of the Company and the Trustee and the beneficiaries of the trust with respect to said property, and to the Trustee and its successor or successors in the trust, in the same manner and with the same effect as if the said property had been owned by the Company at the time of the execution of the Mortgage, and had been specifically and at length described in and conveyed to said Trustee by the Mortgage as a part of the property therein stated to be conveyed. The Company further covenants and agrees to and with the Trustee and its successor or successors in such trust under the Mortgage, as follows: ARTICLE II THIRTEENTH SERIES OF BONDS SECTION 2.01.

The person in whose name any bond of the Thirteenth Series is registered at the close of business on any record date (as hereinafter defined) for the Thirteenth Series with respect to any interest payment date shall be entitled to receive the interest payable on such interest payment date (except that in case of any redemption of bonds as provided for herein on a date subsequent to the record date for the Thirteenth Series and prior to such interest payment date, interest on such redeemed bonds shall be payable only to the date fixed for redemption thereof and only against surrender of such bonds for redemption in accordance with the notice of such redemption) notwithstanding the cancellation of such bond upon any transfer or exchange thereof subsequent to the record date for the Thirteenth Series and prior to such interest payment date, except if, and to the extent that, the Company shall default in the payment of the interest due on such interest payment date, in which case such defaulted interest shall be paid to the persons in whose names outstanding bonds of the Thirteenth Series are registered on the day immediately preceding the date of payment of such defaulted interest. Any bond of the Thirteenth Series issued upon any transfer or exchange subsequent to the record date for the Thirteenth Series for any interest payment date and prior to such interest payment date shall bear interest from such interest payment date.

(VI) Bonds of the Thirteenth Series shall be transferable, subject to any restrictions thereon set forth in any such bond of the Thirteenth Series, upon the surrender therefor for cancellation, together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York. Upon any transfer or exchange of bonds of the Thirteenth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other government charge, as provided in Section 2.08 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Thirteenth Series. (VII) After the execution and delivery of this Eleventh Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage and this Eleventh Supplemental Indenture, it is contemplated that there shall be an issue of bonds of the Thirteenth Series in an aggregate principal amount not to exceed Thirteen Million Two Hundred Thirty-Four Thousand Dollars ($13,234,000). Bonds of the Thirteenth Series shall be issued pro rata on the basis of Class "A" Bonds of the Fifty-ninth Series, designated "Adjustable Rate Replacement Series," issued under each of the Utah Mortgage and the Pacific Mortgage and delivered to the Trustee. The claim of the registered owner of any such Class "A" Bond shall be limited to the principal amount of the bonds of the Thirteenth Series issued and Outstanding on the basis of such Class "A" Bond. (IX) Upon receipt by the Trustee from time to time of a written request or requests (stating that the Trustee holds an aggregate principal amount of Class "A" Bonds of the Fifty-ninth Series, designated "Adjustable Rate Replacement Series Bonds," issued under the Utah Mortgage and the Pacific Mortgage which exceeds the principal amount of bonds of the Thirteenth Series then Outstanding and stating the amount of such excess and the principal amount of any such Class "A" Bonds to be canceled) executed by an Authorized Executive Officer of the Company, the Trustee shall return to the corporate trustee under the Utah Mortgage or corporate trustee under the Pacific Mortgage, as the case may be, for cancellation, a principal amount of Class "A" Bonds issued in the name of and held by the Trustee with respect to bonds of the Thirteenth Series not to exceed the excess of the principal amount of such Class "A" Bonds then so held over the principal amount of bonds of the Thirteenth Series then Outstanding. Upon cancellation of any such principal amount of Class "A" Bonds, the Trustee shall receive from the corporate trustee 8 under the Utah Mortgage or corporate trustee under the Pacific Mortgage, as the case may be, a Class "A" Bond in the principal amount not so canceled. ARTICLE III FOURTEENTH SERIES OF BONDS SECTION 3.01. The terms defined in this Article III shall, for purposes of this Article III, have the meaning specified, unless the context otherwise requires: The term "Loan Agreement" shall mean the Loan Agreement dated as of July 22, 1987, entered into among the Company, the Agent, and the Lenders (as defined below), as such Loan Agreement has been amended by that certain First Amendment to Loan Agreement, dated as of December 1, 1995. The term "Lenders" shall mean The Long-Term Credit Bank of Japan, Limited, and The Dai-Ichi Mutual Life Insurance Company, and their successors and assigns.

SECTION 3.02. There shall be a series of bonds designated "9 3/8% Replacement Series Due 1997" (herein sometimes referred to as the Fourteenth Series), each of which shall also bear the descriptive title "First Mortgage and Collateral Trust Bond," and which shall be in substantially the form of attached Exhibit B and shall contain suitable provisions with respect to the matters hereinafter in this Section specified. (I) Bonds of the Fourteenth Series shall mature on July 22, 1997, shall be issued as fully registered bonds in the denomination of Five Thousand Dollars and, at the option of the Company, of any multiple or multiples of Five Thousand Dollars (the exercise of such option to be evidenced by the execution and delivery thereof). (II) Bonds of the Fourteenth Series shall bear interest at the rate of nine and three-eighths per centum (9 3/8%) per annum, payable semi annually on January 22 and July 22 of each year, commencing January 22, 1996, and have such other terms and 9 provisions as set forth in the form attached hereto. Bonds of the Fourteenth Series shall be dated the date of authentication and shall accrue interest from July 22, 1995. (III) The principal of and interest on each bond of the Fourteenth Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts. (IV) Bonds of the Fourteenth Series shall be redeemable in whole at any time upon receipt by the Trustee of a written demand (hereinafter referred to as the "Redemption Demand") from the Agent, which Redemption Demand shall be received not less than 60 days prior to the redemption date stated therein. The Redemption Demand shall be signed by a General Manager and Agent, Vice President and Deputy General Manager, or Assistant Vice President and Manager of the Agent and shall state (1) the principal amount of bonds of the Fourteenth Series to be redeemed (which shall be equal to the aggregate principal amount of the then outstanding Bonds of the Fourteenth Series), (2) the redemption date (hereinafter referred to as the "redemption date"), (3) that the redemption required by the Redemption Demand is the result of the Advance then outstanding under the Loan Agreement having been declared immediately due and payable pursuant to the provisions of the Loan agreement (hereinafter referred to as an "Acceleration"), (4) that the Trustee shall call for redemption on the redemption date the stated principal amount of bonds of the Fourteenth Series, and (5) that the Agent, as holder of all the bonds of the Fourteenth Series then outstanding, waives any notice of such redemption required to be given under the Mortgage. The redemption date stated in the Redemption Demand shall not be less than 60 days after the receipt thereof by the Trustee, provided that the provisions of this Article III shall not be construed as limiting any rights of the Agent, as holder of the bonds of the Fourteenth Series pursuant to Article XV of the Mortgage and, provided, further, that if after receipt of the Redemption Demand and prior to the redemption date the Trustee shall have been advised in writing by the Agent, signed in the same manner as the Redemption Demand, that the Acceleration has been rescinded, such Redemption Demand shall thereupon without further act of the Trustee be rescinded and become null and void for all purposes hereunder and no redemption of the bonds of the Fourteenth Series and no payment in respect thereof shall be effected or required. Promptly after receiving the Redemption Demand the Trustee shall mail a copy thereof to the Company; provided, however, that failure to mail a copy of the Redemption Demand shall not affect the validity of the proceedings for the redemption of the bonds of the Fourteenth Series. The Trustee may conclusively rely on the statements and instructions contained the Redemption Demand. Redemption of bonds of the Fourteenth Series shall be at the principal amount thereof, together with accrued interest to the redemption date, and such amount shall become and be due and payable on the redemption date. The Company hereby covenants that, if a Redemption Demand shall be delivered to the Trustee, the Company, subject to Paragraph (VI) of this Section 3.02, will deposit, on or before the business day preceding the redemption date, with the Trustee, an amount in cash sufficient to redeem the bonds of 10 the Fourteenth Series so called for redemption. To the extent the method of redemption provided for in this Paragraph (IV) conflicts with any provisions of Article XII of the Mortgage, such provisions of Article XII shall not be applicable. (V) At any time and from time to time upon receipt by the Trustee of bonds of the Fourteenth Series, together with a written order from the Agent signed in the same manner as a Redemption Demand (i) specifying the principal amount of bonds of the Fourteenth Series to be canceled and the reason therefor and (ii) directing the Trustee to cancel the bonds so delivered or to make such endorsements thereon as shall be appropriate pursuant to Section 12.04 of the Mortgage to evidence the cancellation of the principal amount of bonds of the Fourteenth Series stated in clause (i) to be canceled, the Trustee shall cancel such stated principal amount of bonds of the Fourteenth Series. The Trustee may conclusively rely on the statements and instructions contained in such order. (VI) The obligation of the Company to make payments with respect to the principal of and interest on bonds of the Fourteenth Series shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due principal of and interest on the Advance shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the Advance means that if any payment is made on the principal of or interest on the Advance, a corresponding payment obligation with respect to the principal of or interest on the Bonds shall be deemed discharged in the same proportion as the payment with respect to the Advance discharges the outstanding obligation with respect to the Advance. The Trustee may conclusively presume that the obligation of the Company to make payments with respect to the principal of and interest on bonds of the Fourteenth Series shall have been fully satisfied and discharged unless and until the Trustee shall have received a written notice from the Agent, signed by a General Manager and Agent, Vice President and Deputy General Manager or Assistant Vice President and Manager, stating (i) that timely payment of the principal of or interest on the Advance has not been made and (ii) the amount of funds required to make such payment of principal or interest or both, as the case may be. The Trustee may conclusively rely on the statements contained in the notice described in the preceding sentence. (VII) Bonds of the Fourteenth Series shall only be transferable (subject to the provisions of Section 2.08 of the Mortgage), upon the surrender thereof, for cancellation, together with a written instrument of transfer in form approved by the Company duly executed by the registered owner or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York, to a successor to the Agent pursuant to the Loan Agreement, and such bonds of the Fourteenth Series will have the following legend imprinted thereon: "This Bond has not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in contravention of said Act and 11 is not transferable except to a successor Agent under the Loan Agreement, dated as of July 22, 1987 among PacifiCorp, The Long-Term Credit Bank of Japan, Limited, as agent, and the financial institutions named therein, as amended." (VIII) Upon any transfer of bonds of the Fourteenth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other governmental charge, as provided in Section 2.08 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any transfer of bonds of the Fourteenth Series. After the execution and delivery of this Eleventh Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage, as supplemented, it is contemplated that there shall be an issue of bonds of the Fourteenth Series for the aggregate principal amount of Fifty Million United States Dollars ($50,000,000). (IX) Upon receipt by the Trustee from time to time of a written request or requests (stating that the Trustee holds an aggregate principal amount of Class "A" Bonds of the Sixtieth Series, designated "First Mortgage Bond 9 3/8% Replacement Series Due 1997," issued under the Utah Mortgage and the Pacific Mortgage, which exceeds the principal amount of bonds of the Fourteenth Series then Outstanding and stating the amount of such excess and the principal amount of any such Class "A" Bonds to be canceled) executed by an Authorized Executive Officer of the Company, the Trustee shall return to the corporate trustee under the Utah Mortgage or corporate trustee under the Pacific Mortgage, as the case may be, for cancellation, a principal amount of Class "A" Bonds issued in the name of and held by the Trustee with respect to bonds of the Fourteenth Series not to exceed the excess of the principal amount of such Class "A" Bonds then so held over the principal amount of bonds of the Fourteenth Series then Outstanding. Upon cancellation of any such principal amount of Class "A" Bonds, the Trustee shall receive from the corporate trustee under the Utah Mortgage or corporate trustee under the Pacific Mortgage, as the case may be, a Class "A" Bond in the principal amount not so canceled. ARTICLE IV FIFTEENTH SERIES OF BONDS SECTION 4.01. There shall be a series of bonds designated "Bond Credit Series Bonds" (herein sometimes referred to as the Fifteenth Series), each of which shall also bear the descriptive title "First Mortgage and Collateral Trust Bond," and the form thereof, which shall be established by or pursuant to a Resolution, shall contain suitable provisions with respect to the matters hereinafter in this Section specified. 12 (I) Bonds of the Fifteenth Series shall mature on such date or dates not more than 30 years from the date of issue as shall be set forth in or determined in accordance with a Resolution filed with the Trustee and, unless otherwise established by or pursuant to a Resolution, shall be issued as fully registered bonds in the denomination of Five Thousand Dollars and, at the option of the Company, of any multiple or multiples of Five Thousand Dollars (the exercise of such option to be evidenced by the execution and delivery thereof). (II) Bonds of the Fifteenth Series shall bear interest at such rate or rates (which may either be fixed or variable), payable on such dates, and have such other terms and provisions not inconsistent with the Mortgage as may be set forth in or determined in accordance with a Resolution filed with the Trustee. Bonds of the Fifteenth Series shall be dated and shall accrue interest as provided in Section 2.06 of the Mortgage. Interest payable on any bond of the Fifteenth Series and punctually paid or duly provided for on any interest payment date for such bond will be paid to the person in whose name the bond is registered at the close of business on the Record Date (as hereinafter specified) for such bond next preceding such interest payment date; provided, however, that the first payment of interest on any bond with an Issue Date (as hereinafter specified) between a Record Date and an interest payment date will be made on the interest payment date following the next succeeding Record Date to the registered owner on such next Record Date (unless the Company elects, in its sole discretion, to pay such interest on the first interest payment date after the Issue Date, in which case such interest will be paid to the person in whose name the bond is originally issued), provided, further, that interest payable at maturity or upon earlier redemption will be payable to the person to whom principal shall be payable. The "Record Date" with respect to bonds of the Fifteenth Series of a designated interest rate and maturity shall be determined by or in accordance with a Resolution filed with the Trustee. "Issue Date" with respect to bonds of the Fifteenth Series of a designated interest rate and maturity shall mean the date of first authentication of bonds of such designated interest rate and maturity. Any interest on any bond of the Fifteenth Series which is payable but is not punctually paid or duly provided for, on any interest payment date for such bond (herein called "Defaulted Interest"), shall forthwith cease to be payable to the registered owner on the relevant Record Date for the payment of such interest solely by virtue of such owner having been such owner; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in subsection (i) or (ii) below: (i) The Company may elect to make payment of any Defaulted Interest on the bonds of the Fifteenth Series to the persons in whose names such bonds are registered at the close of business on a Special Record Date (as hereinafter defined) for the payment of such Defaulted Interest, which shall be fixed in the following manner: The Company shall, at least 30 days prior to the proposed date of payment, notify the Trustee in writing (signed by an Authorized Financial Officer of 13 the Company) of the amount of Defaulted Interest proposed to be paid on each bond of the Fifteenth Series and the date of the proposed payment (which date shall be such as will enable the Trustee to comply with the next sentence hereof), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the persons entitled to such Defaulted Interest as in this subsection provided and not to be deemed part of the Mortgaged and Pledged Property. Thereupon, the Trustee shall fix a record date (herein referred to as a "Special Record Date") for the payment of such Defaulted Interest which date shall be not more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each registered owner of a bond of the Fifteenth Series at his address as it appears in the bond register not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the persons in whose names the bonds of the Fifteenth Series are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following subsection (ii). (ii) The Company may make payment of any Defaulted Interest on the bonds of the Fifteenth Series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such bonds may be listed and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this subsection, such payment shall be deemed practicable by the Trustee. Subject to the foregoing provisions of this Section, each bond of the Fifteenth Series delivered under the Mortgage upon transfer of or in exchange for or in lieu of any other bond shall carry all the rights to interest accrued and unpaid, and to accrue, which were carried by such other bond and each such bond shall bear interest from such date, that neither gain nor loss in interest shall result from such transfer, exchange or substitution. (III) The principal of and interest on each bond of the Fifteenth Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts or in such other currency or currency unit as shall be determined by or in accordance with a Resolution filed with the Trustee. 14 (IV) Each bond of the Fifteenth Series may be redeemable prior to maturity at the option of the Company, as determined by or in accordance with a Resolution filed with the Trustee. (V) Each bond of the Fifteenth Series may be subject to the obligation of the Company to redeem such bond, as determined by or in accordance with a Resolution filed with the Trustee. (VI) Each bond of the Fifteenth Series may have such other terms as are not inconsistent with Section 2.03 of the Mortgage, including, without limitation, terms and conditions regarding interest rates and the payment thereof, place or places for payment, exchange privileges, rights with respect to redemption, prepayment or purchase, and default provisions, and as may be determined by or in accordance with a Resolution filed with the Trustee. (VII) At the option of the registered owner, any bonds of the Fifteenth Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series of other authorized denominations. (VIII) Bonds of the Fifteenth Series shall be transferable, subject to any restrictions thereon set forth in any such bond of the Fifteenth Series, upon the surrender therefor for cancellation, together with a written instrument of transfer in form approved by the registrar duly executed by the registered owner or by his, her or its duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York. Upon any transfer or exchange of bonds of the Fifteenth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other government charge, as provided in Section 2.08 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Fifteenth Series. (IX) After the execution and delivery of this Eleventh Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage and this Eleventh Supplemental Indenture, it is contemplated that there shall be an issue of bonds of the Fifteenth Series in an aggregate principal amount not to exceed Four Hundred Ninety-Eight Million Five Hundred Eighty-Nine Thousand Seven Hundred Fifty-Three Dollars ($498,589,753). Bonds of the Fifteenth Series shall be issued on the basis of Class "A" Bonds of the Sixty-first Series, designated "Bond Credit Series Bonds," issued under each of the Utah Mortgage and the Pacific Mortgage and delivered to the Trustee. The claim of the registered owner of any such Class "A" Bond shall be limited to the principal amount of the bonds of the Fifteenth Series issued and Outstanding on the basis of such Class "A" Bond. 15 (X) Upon receipt by the Trustee from time to time of a written request or requests (stating that the Trustee holds an aggregate principal amount of Class "A" Bonds of the Sixty-first, designated "Bond Credit Series Bonds," issued under the Utah Mortgage and the Pacific Mortgage which exceeds the principal amount of bonds of the Fifteenth Series then Outstanding and stating the amount of such excess and the principal amount of any such Class "A" Bonds to be canceled) executed by an Authorized Executive Officer of the Company, the Trustee shall return to the corporate trustee under the Utah Mortgage or corporate trustee under the Pacific Mortgage, as the case may be, for cancellation, a principal amount of Class "A" Bonds issued in the name of and held by the Trustee with respect to bonds of the Fifteenth Series not to exceed the excess of the principal amount of such Class "A" Bonds then so held over the principal amount of bonds of the Fifteenth Series then Outstanding. Upon cancellation of any such principal amount of Class "A" Bonds, the Trustee shall receive from the corporate trustee under the Utah Mortgage or corporate trustee under the Pacific Mortgage, as the case may be, a Class "A" Bond in the principal amount not so canceled.

This bond is one of an issue of bonds of the Company issuable in series and is one of a series known as its First Mortgage and Collateral Trust Bonds, Adjustable Rate Replacement Series, to be issued under and equally secured by a Mortgage and Deed of Trust (herein, together with any indenture supplemental thereto, including the supplemental indenture dated as of December 1, 1995, called the Mortgage), dated as of January 9, 1989 executed by the Company to Morgan Guaranty Trust Company of New York, as Trustee (Chemical Bank, successor). Reference is made to the Mortgage for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustee in respect thereof, the duties and immunities of the Trustee and the terms and conditions upon which the bonds are, and are to be, secured, the circumstances under which additional bonds may be issued and the definitions of certain terms hereinafter used. With the consent of the Company and to the extent permitted by and in the manner provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least sixty per centum (60%) in principal amount of bonds then Outstanding under the Mortgage, all voting as a single class or, if the rights of the holders of one or more, but less than all, series of bonds then Outstanding are to be adversely affected, then by affirmative vote of the holders of at least sixty per centum (60%) in principal amount of those bonds then Outstanding so to be adversely affected, all voting as a single class (excluding in any case bonds disqualified from voting by reason of the Company's interest therein as provided in the Mortgage); provided that no such modification or alteration shall, without the consent of the holder hereof, impair or affect the right of the holder to receive payment of the principal of (and premium, if any) and interest on this bond, on or after the respective due dates expressed herein, or to institute suit for the enforcement of any such payment on or after such respective dates, or permit the creation of any lien ranking equal or prior to the Lien of the Mortgage or deprive the holder of the benefit of a lien on the Mortgaged and Pledged Property or reduce the percentage vote required to effect such modifications or alterations. The Company has reserved the right, without any consent or other action by holders of bonds of the Eighth series known as First Mortgage and Collateral Trust Bonds 6 3/4% series due April 1, 2005, or any series of bonds subsequently created under the Mortgage (including the bonds of this series), to amend the Mortgage in order to except from the Lien of the Mortgage allowances allocated to steam-electric generating plants owned by the Company, or in which the Company has interests, pursuant to Title IV of the Clean Air Act Amendments of 1990 as now in effect or as hereafter supplemented or amended. 2. Interest on this bond is payable at a rate per annum determined as follows: A. Interest on this bond is payable (i) at the rate of 10% per annum for the period from the date hereof to and including October 31, 1996*, and (ii) at a rate per annum equal to the Adjusted Rate (as defined below) for the 12-month period thereafter commencing on November 1, in each year (each such 12-month period being herein called an Applicable Period and each such November 1, being herein called an Adjustment Date). The Adjusted Rate for the Applicable Period commencing on any Adjustment Date shall be (i) the Base Treasury Rate or the Alternate Treasury Rate (each as defined below), as the case may be, determined for such Applicable Period in - ------------------------- *The matter in brackets will be set forth in the bonds of this series originally issued and in any bonds of this series issued upon a transfer or substitution or exchange of bonds of this series on or before October 31, 1996. Any bonds of this series so issued thereafter shall specify the Adjusted Rate then in effect and the last day of the then current Applicable Period. 2 accordance with the Procedures (as defined and set forth below), times 127%, rounded to the nearest one tenth of one percentage point or (ii) under the circumstances described in paragraph F below, the rate determined by Banking Firms (as defined below) for such Applicable Period in accordance with said paragraph F, times 127%, rounded to the nearest one tenth of one percentage point; provided, however, that the Adjusted Rate for any Applicable Period shall in no event be less than 10% per annum or greater than 24% per annum. If for any reason beyond the control of the Company, neither the Base Treasury Rate nor the Alternate Treasury Rate shall have been so determined for any Applicable Period prior to the December 1 next succeeding the Adjustment Date for such Applicable Period, the Adjusted Rate for such Applicable Period shall be the interest rate per annum in effect on the October 31 next preceding such Adjustment Date; provided, however, that any rate thereafter determined for such Applicable Period in accordance with paragraph F below shall be deemed to supersede such rate for (and only for) any portion of such Applicable Period occurring on or after the date of such determination. B. The Base Treasury Rate for the Applicable Period commencing on any Adjustment Date shall be the arithmetic average of the four most recent weekly average yields to maturity for actively traded marketable U.S. Treasury fixed interest rate securities (adjusted to constant maturities of ten years), as published by the Federal Reserve Board in its Statistical Release H.15 (or published in another publication or release referred to in the immediately following sentence) published at least five days prior to such Adjustment Date; provided that such weekly average yields to maturity as so published shall have been computed with respect to weekly periods ended within 50 days prior to such Adjustment Date. If one or more of such Statistical Releases containing such weekly average yields to maturity shall not be available, the Base Treasury Rate shall be determined with reference to any comparable release of such Board substituted therefor or, if such Board shall not publish a comparable release, with reference to any official publication or release of any other U.S. Governmental department or agency that purports to set forth such weekly average yields to maturity (or purports to set forth daily average yields to maturity from which such weekly average yields to maturity can be mathematically derived), adjusted to constant maturities of ten years, in accordance with the Treasury Criteria (as defined below) or other criteria that are substantially equivalent to Treasury Criteria, as determined by the holders of at least 66 2/3% in amount of the bonds of this series then outstanding. In August 1982, such weekly average yields to maturity were determined on the basis of the criteria (herein called the Treasury Criteria) set forth in an attachment to Federal Reserve Board Statistical Release H.15 dated May 14, 1982, and reflected in such Board's Statistical Release H.15, dated August 16, 1982. C. The Alternate Treasury Rate for the Applicable Period commencing on any Adjustment Date shall be the arithmetic average of the average yields to maturity of the closing bids quoted daily (or less frequently, if daily quotations shall not be available) by each of the three Government Securities Dealers (as defined below) 3 designated in accordance with the Procedures, during the 28-day period ending five days prior to such Adjustment Date, for actively traded marketable U.S. Treasury fixed interest rate securities with a final maturity date of at least eight and one-half years but not more than eleven and one-half years from the date of each such quotation (other than securities which can, at the option of the holder, be surrendered at face value in payment of any Federal estate tax and securities which provide tax benefits to the holder and are priced to reflect such tax benefits and securities which were originally issued at a deep or substantial discount). D. The Adjusted Rate for the Applicable Period commencing on any Adjustment Date shall be determined in accordance with the following procedures (herein called the Procedures) or paragraph F below, as the case may be: (1) On or before the second day next preceding such Adjustment Date the Company will deliver to the holder of this bond and to the Trustee a certificate, signed by the principal financial officer of the Company (herein called an Adjustment Certificate), either (a) setting forth the Base Treasury Rate for the Applicable Period commencing on such Adjustment Date, determined as above provided (and accompanied by copies of each Statistical Release H.15 or other publication or release used in determining such Base Treasury Rate), whereupon such Base Treasury Rate shall be used to compute the Adjusted Rate for such Applicable Period, or (b) stating that (i) one or more of the Statistical Releases H.15 (or other publication or release) necessary for determining such Base Treasury Rate were not available for the four weeks next preceding such Adjustment Date, and/or (ii) the Treasury Criteria were not in effect for such four- week period and, for reasons specified in such certificate, the criteria determined to be substantially equivalent to the Treasury Criteria by the holders of at least 66 2/3% in amount of the bonds of this series then outstanding, pursuant to paragraph B above, are not, in the reasonable and good faith judgment of the Company, substantially equivalent to the Treasury Criteria, and setting forth the Alternate Treasury Rate for the Applicable Period commencing on such Adjustment Date, determined as above provided (such Adjustment Certificate to be accompanied by copies of the reports from which such Alternate Treasury Rate was so determined from three Government Securities Dealers designated by the Trustee), whereupon such Alternate Treasury Rate shall be used to compute the Adjusted Rate for such Applicable Period. (2) A "Government Securities Dealer" shall mean Morgan Guaranty Trust Company of New York or any other nationally recognized commercial bank or investment banking firm actively engaged in the trading of U.S. Treasury fixed interest rate securities of the types reflected in the Treasury Criteria. 4 (3) In the event that during any Applicable Period there shall occur (whether by reason of republication to correct an error or otherwise) any change in the published data used as a basis for determination of the Base Treasury Rate (and, therefore, the Adjusted Rate) then in effect with respect to such Applicable Period, the Company will, within 30 calendar days thereafter, deliver to the holder of this bond and to the Trustee a new adjustment Certificate setting forth the new Base Rate and the other information required by the foregoing Clause (1) with respect to such new Base Treasury Rate, whereupon such new Base Treasury Rate shall be used to recompute the Adjusted Rate with respect to such Applicable Period, and such new Adjusted Rate shall be applicable retroactively from and after the Adjustment Date on which such Applicable Period commenced; provided, however, that the Company need only take such action is such change in the published data shall occur on a date no later than 90 calendar days after the beginning of such Applicable Period. (4) If (i) the holders of at least 33 1/3 %in amount of the bonds of this series then outstanding or (ii) any of the original holders of the bonds of this series shall deliver to the Company, the Trustee and each other holder of outstanding bonds of this series, within 15 days after the Company's delivery of an Adjustment Certificate with respect to any Applicable Period pursuant to the foregoing Clause (1) or Clause (3), written notice to the effect that, for reasons specified in such notice, the Base Treasury Rate set forth in such Adjustment Certificate has not been determined in accordance with the Treasury Criteria or other criteria then in effect pursuant to paragraph B above, then the Company will deliver to the holder of this bond, within 10 working days after the receipt of such written notice, a second Adjustment Certificate (a) setting forth the Alternate Treasury Rate for such Applicable Period determined as above provided (and accompanied by copies of the reports from which such Alternate Treasury Rate was so determined from three Government Securities Dealers designated by the Trustee), whereupon such Alternate Treasury Rate shall be used to compute the Adjusted Rate for such Applicable Period, or (b) stating that for reasons beyond the control of the Company, the Alternate Treasury Rate for such Applicable Period cannot be determined, and setting forth in reasonable detail the efforts made to determine such rate, whereupon it shall be deemed that for reasons beyond the control of the Company neither the Base Treasury Rate nor the Alternate Treasury Rate has been determined for such Applicable Period. E. The Company will keep a copy of each Adjustment Certificate at its principal executive office and permit any holder of any of the bonds of this series (or any prospective purchaser of any of the bonds of this series designated by the holder thereof) to inspect such Adjustment Certificate upon request. 5 F. If for any reason beyond the control of the Company, neither the Base Treasury Rate nor the Alternate Treasury Rate shall have been determined for any Applicable Period in accordance with the Procedures prior to the December 1 nest succeeding the Adjustment Date on which such Applicable Period commences, the Company (i) will give written notice to each holder of any bonds of this series and to the Trustee, in each case within five business days after such December 1, specifying the reasons why neither the Base Treasury Rate nor the Alternate Treasury Rate shall have been so determined and (ii) will keep a copy of such notice at its principal executive office and permit any holder of any of the bonds of this series (or any prospective purchaser of any of the bonds of this series designated by the holder thereof) to inspect such notice upon request. Within 10 calender days after the giving of such notice the Company shall designate two Banking Firms, and within ten calendar days after receipt of such notice the holders of at least 66 2/3 % in amount of the bonds of this series then outstanding shall designate two Banking Firms. The four Banking Firms so designated shall, within 10 calendar days after the last of said Banking Firms shall have been so designated, designate a fifth Banking Firm. (If within such 10 calendar day period, the four Banking Firms do not agree upon the appointment of a fifth Banking Firm, then either the Company or the requisite holders, as the case may be, on behalf of both, may request such appointment by the then President of the Association of the Bar of the City of New York (or any organization successor thereto) or in his absence, failure, refusal or inability to act, then either the Company or the requisite holders, as the case may be, may apply to the Supreme Court, New York County, for the appointment of such fifth Banking Firm and the other party shall not raise any question as to the court's full power and jurisdiction to entertain the application and make the appointment.) For purposes of this paragraph, a "Banking Firm" shall mean Morgan Guaranty Trust Company of New York or any nationally recognized commercial bank or investment banking firm that was within the 12-month period prior to its designation actively engaged in the trading of U.S. Treasury fixed interest rate securities of the types reflected in the Treasury Criteria. Each Banking Firm so designated shall notify the Trustee and the Company in writing, not later than 10 calendar days after its designation as hereinabove provided, of the yield to maturity which, in its reasonable and good faith judgement, would then be obtainable for marketable U.S. Treasury fixed interest rate securities with a final maturity date of ten years from the date of such notice (other than securities which can, at the option of the holder, be surrendered at face value in payment of any Federal estate tax and securities which provide tax benefits to the holder and are priced to reflect such tax benefits and securities which were originally issued at a deep or substantial discount). The arithmetic average of said yields to maturity set forth in said notices of said five Banking Firms, times 127%, rounded to the nearest one tenth of one percentage point, shall be the Adjusted Rate with respect to such Applicable Period, and such Adjusted Rate shall be applicable for the remainder of such Applicable Period. The Company will give prompt written notice to each holder of any bonds of this series and the Trustee of such new Adjusted Rate (such notice to be accompanied by copies of the written notices of said five Banking Firms). Notwithstanding anything herein to the 6 contrary, if the Company or the requisite holders shall fail to designate one or both Banking Firms within the time period set forth above or if any of the Banking Firms designated by the Company or the requisite holders shall refuse to participate in the selection of a fifth Banking Firm required by the third or fourth sentence of this paragraph, then the arithmetic average of the yields to maturity set forth in the written notices of the Banking Firms designated or participating, as the case may be, times 127%, rounded to the nearest one-tenth percentage point, shall be the Adjusted Rate with respect to such Applicable Period, and such Adjusted Rate shall be applicable for the remainder of such Applicable Period. 3. The principal hereof may be declared or may become prior to the maturity date hereinbefore named on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a Default as in the Mortgage provided. 4 This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, the City of New York, upon surrender and cancellation of this bond, together with a written instrument of transfer, if required by the Company, duly executed by the registered owner or by his duly authorized attorney, and, thereupon, a new fully registered bond of the same series for a like principal amount will be issued to the transferee in exchange hereof as provided in the Mortgage. Subject to the foregoing provisions as to the person entitled to receive payment of interest hereon, the Company and the Trustees may deem and treat the person in whose name this bond is registered as the holder and the absolute owner hereof for the purpose of receiving payment and for all other purposes, and neither the Company nor the Trustees shall be affected by any notice to the contrary. 5. In the manner prescribed in the Mortgage, any bonds of this series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, are exchangeable for a like aggregate principal amount of fully registered bonds of the same series of other authorized denominations. 6. The bonds of this series are redeemable (as more fully set forth in the Supplemental Indenture dated as of December 1, 1995 to the Mortgage) at the option of the Company at any time (or from time to time) on or after November 1, 1996 and prior to maturity, either as a whole or in part, upon the notice (which may state that such redemption shall be made subject to the receipt of the redemption moneys by the Trustee before the date fixed for redemption) mailed at least thirty (30) and not more than sixty (60) days prior to the date fixed for redemption, at the following general redemption prices, expressed in percentages of the principal amount of the bonds to be redeemed: 7 GENERAL REDEMPTION PRICES If redeemed during the twelve months on the thirty-first day of October, 1997........104.41% 2000...........101,76% 1998........103.53 2001...........100.88 1999........102.64 2002...........100.00 in each case, together with accrued interest to the date for redemption. 7. As provided in the Mortgage, the Company shall not be required to make transfers or exchanges of bonds of any series for a period of fifteen (15) days next preceding any designation of bonds of such series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds designated in whole or in part for redemption. 8.

With the consent of the Company and to the extent permitted by and in the manner provided in the Mortgage, the rights and obligations of the Company and/or the rights of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage may be modified or altered by affirmative vote of the holders of at least sixty per centum (60%) in principal amount of bonds then Outstanding under the Mortgage, all voting as a single class or, if the rights of the holders of one or more, but less than all, series of bonds then Outstanding are to be adversely affected, then by affirmative vote of the holders of at least sixty per centum (60%) in principal amount of those bonds then Outstanding so to be adversely affected, all voting as a single class (excluding in any case bonds disqualified from voting by reason of the Company's interest therein as provided in the Mortgage); provided that no such modification or alteration shall, without the consent of the holder hereof, impair or affect the right of the holder to receive payment of the principal of (and premium, if any) and interest on this bond, on or after the respective due dates expressed herein, or to institute suit for the enforcement of any such payment on or after such respective dates, or permit the creation of any lien ranking equal or prior to the Lien of the Mortgage or deprive the holder of the benefit of a lien on the Mortgaged and Pledged Property or reduce the percentage vote required to effect such modifications or alterations.

Satisfaction of any obligation to the extent that payment is made with respect to the Advance means that if any payment is made on the principal of or interest on the Advance, a 2 corresponding payment obligation with respect to the principal of or interest on the Bonds shall be deemed discharged in the same proportion as the payment with respect to the Advance discharges the outstanding obligation with respect to the Advance.
