There is hereby created a series of bonds designated as hereinabove set forth (said bonds being sometimes herein referred to as the "bonds of the Forty-seventh Series") and the form thereof shall be substantially as hereinabove set forth. Bonds of the Forty-seventh Series shall mature on the date specified in the form thereof hereinabove set forth, and the definitive bonds of such series shall be issued only as registered bonds without coupons. Bonds of the Forty-seventh Series shall be in such denominations as the Board of Directors shall approve, and execution and delivery thereof to the Trustee for authentication shall be conclusive evidence of such approval. The serial numbers of bonds of the Forty-seventh Series shall be such as may be approved by any officer of the Company, the execution thereof by any such officer to be conclusive evidence of such approval.

However, notwithstanding the provisions of Section 2.05 of the Indenture, no charge shall be made upon any transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company. The person in whose name any bond of the Forty-seventh Series is registered at the close of business on any record date (as hereinbelow defined) with respect to any interest payment date shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such bond upon any transfer or exchange thereof subsequent to the record date and prior to such interest payment date, except if and to the extent 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 person in whose name such bond (or any bond or bonds issued, directly or after intermediate transactions, upon transfer or exchange or in substitution thereof) is registered on a subsequent record date for such payment established as hereinafter provided. A subsequent record date may be established by the Company by notice mailed to the holders of bonds not less than ten days preceding such record date, which record date shall be not less than five nor more than thirty days prior to the subsequent interest payment date. The term "record date" as used in this Section with respect to any regular interest payment date shall mean the April 15 or October 15, as the case may be, next preceding such interest payment date, or, if such April 15 or October 15 shall be a legal holiday or a day on which banking institutions in the Borough of Manhattan, The City of New York, are authorized by law to close, the next preceding day which shall not be a legal holiday or a day on which such institutions are so authorized to close.

However, so long as there is no existing default in the payment of interest on such bonds, the holder of any bond authenticated by the Trustee between the record date for any interest payment date and such interest payment date shall not be entitled to the payment of the interest due on such interest payment date and shall have no claim against the Company with respect thereto; provided, further, that if and to the extent the Company shall default in the payment of the interest due on such interest payment date, then any such bond shall bear interest from the May 1 or November 1, as the case may be, next preceding the date of such bond, to which interest has been paid or, if the Company shall be in default with respect to the interest due on May 1, 1997, then from November 1, 1996.

Any or all of the bonds of the Forty-seventh Series shall be redeemable at the option of the Company, at any time and from time to time, prior to maturity, upon notice given by mailing the same, by first class mail postage prepaid, not less than thirty nor more than forty-five days prior to the date fixed for redemption to each registered holder of a bond of the Forty-seventh Series to be redeemed (in whole or in part) at the last address of such holder appearing on the registry books, at a regular redemption price equal to the greater of (i) 100% of the principal amount of the bonds of the Forty-seventh Series being redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal of and interest on the bonds of the Forty-seventh Series being redeemed discounted to the date of redemption on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at a discount rate equal to the Treasury Yield plus 5 basis points, plus, for (i) or (ii) above, whichever is applicable, accrued interest on such bonds to the date of redemption. "Treasury Yield" means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

The term "improvement fund certificate", as used in this Section, shall mean an accountant's certificate filed by the Company with the Trustee pursuant to this Section. Such certificate may be a separate certificate or it may be combined with an improvement fund certificate or certificates filed pursuant to the improvement fund provisions of the Indenture or of any other indenture or indentures supplemental thereto. On or before the first day of June in each year, beginning June 1, 1997, so long as any bonds of the Forty-seventh Series are outstanding under the Indenture, the Company shall deliver to the Trustee an improvement fund certificate showing the improvement fund requirement for that year, the amount of cash, if any, and the principal amount of bonds authenticated under the Indenture then outstanding, if any, then to be deposited by the Company with the Trustee and, if the Company elects to satisfy the improvement fund requirement for that year in whole or in part by the certification of unfunded net property additions, the amount, if any, of unfunded net property additions to be certified.

Interest and expenses in connection with purchases or redemptions pursuant to this Section shall be dealt with as provided in Section 9.05 of the Indenture; or (2) be withdrawn by the Company to the extent of sixty per centum (60%) of the amount of unfunded net property additions certified to the Trustee for such purpose, but only upon receipt by the Trustee of the applicable certificates, opinion of counsel, instruments and cash, if any, required by paragraphs (3), (4), (5), (7), (9) and (10) of Section 4.05 of the Indenture, showing that the Company has unfunded net property additions equal to the amount so certified. Bonds deposited with the Trustee pursuant to this Section, or purchased or redeemed by the use of cash deposited pursuant to this Section, shall be cancelled and shall not be thereafter made the basis for the authentication of bonds, the withdrawal, use or application of cash, or the release of property, under any of the provisions of the Indenture, or thereafter used to satisfy the requirements of this Section or of any other improvement fund provided for in the Indenture or in any indenture supplemental thereto or to satisfy any replacement deficit pursuant to Section 4 of the Supplemental Indenture dated as of October 1, 1964. To the extent that unfunded net property additions are certified to the Trustee to satisfy the improvement fund requirement for any year in whole or in part or as a basis for the withdrawal of cash deposited with the Trustee under the provisions of this Section, the amount of such unfunded net property additions shall thereafter be deducted in computing the amount of unfunded net property additions under Section 1.11 of the Indenture and in computing gross property additions under Section 7.07 of the Indenture.
