As provided in the Indenture, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as in said Indenture provided. With the consent of the Company and to the extent permitted by and as provided in the Indenture, the rights and obligations of the Company and of the holders of the bonds and the terms and provisions of the Indenture, or of any indenture supplemental thereto, may be modified or altered in certain respects by affirmative vote of at least eighty-five percent (85%) in principal amount of the bonds then outstanding, and, if the rights of one or more, but less than all, series of bonds then outstanding are to be affected by the action proposed to be taken, then also by affirmative vote of at least eighty-five percent (85%) in principal amount of the series of bonds so to be affected (excluding in every instance bonds disqualified from voting by reason of the Company's interest therein as specified in the Indenture); provided, however, that, without the consent of the holder hereof, no such modification or alteration shall, among other things, affect the terms of payment of the principal of, or the interest on, this bond, which in those respects is unconditional. The holder of the 1990 Series B Bond, by its acceptance of and holding thereof, consents and agrees that bonds of any series may be issued which mature on a date or dates later than October 1, 2024 and also consents to the deletion from the first paragraph of Section 5 of Article II of the Indenture of the phrase "but in no event later than October 1, 2024."

Determine the present value of each scheduled semi-annual payment of interest and annual retirement of principal by dividing each payment by the Present Value Divisor (PVD), where: ________ PVD = (\/ 1.0 + I) (D) I = That annual interest rate (which has been adjusted for semi-annual compounding) for U.S. Treasury securities, with comparable maturities as set forth in the Federal Reserve statistical release, designated H.15 (519), or its successor, published at least 4 days but not more than 10 days prior to the optional redemption date. The rate shall be the "This Week" rate for Treasury Constant Maturities. Straight line interpolate to 3 decimal places after rounding the prepayment period to the nearest month (1st-15th round down) to match the remaining term of the bond to be redeemed. D = Present value divisor for the preceding 6 month interest period (D equals 1.0 for the period preceding the first period, which is the period from the redemption date to the first scheduled payment date thereafter). Add the present value for all scheduled annual retirements of principal and semi-annual payments of interest to determine the sum to be paid upon redemption of each bond. If the optional redemption payment is greater than the principal outstanding as of the date of optional redemption, the prepayment results in a premium, plus in each case accrued interest to the date fixed for redemption. If the optional redemption payment is less than the principal outstanding as of the date of the optional redemption, the prepayment results in a discount which shall be deducted from the outstanding principal amount which otherwise would have been paid, plus in each case accrued interest to the date fixed for redemption. No redemption pursuant to this paragraph shall be credited to, or relieve the Company to any extent from its obligation to make the principal payment provided for above. In case an event of default, as defined in the Indenture, shall occur, the principal of all the bonds issued thereunder may become or be declared due and payable, in the manner, with the effect and subject to the conditions provided in said Indenture. No recourse shall be had for the payment of the principal of, or the interest on, this bond, or for any claim based hereon or otherwise in respect hereof or of the Indenture, or of any indenture supplemental thereto, against any incorporator, or against any past, present or future stockholder, director or officer, as such, of the Company, or of any predecessor or successor corporation, either directly or through the Company or any such predecessor or successor corporation, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise howsoever, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released by every holder or owner hereof, as more fully provided in the Indenture. 32 29 [FORM OF TRUSTEE'S CERTIFICATE] FORM OF This bond is the only bond of the series designated therein, described TRUSTEE'S in the within- mentioned Indenture.

The aggregate principal amount of bonds of 1990 Series E shall be limited to the principal amount of 1990 Series B Bond being exchanged, except as provided in Sections 7 and 13 of Article II of the Original Indenture with respect to exchanges and replacements of bonds. The bonds of 1990 Series E shall mature on March 31, 2016 and shall be issued in exchange for, and in an aggregate principal amount equal to the principal amount remaining outstanding on, the 1990 Series B Bond as of the date of such exchange. The Bonds of Series E shall be issued as registered bonds without coupons in denominations of $10,000 and any multiple thereof, and shall bear interest, payable semi-annually on March 31 and September 30 of each year (commencing on the first March 31 or September 30 following the date of such exchange), at the rate of seven and 904/1000 per centum (7.904%) per annum until the principal shall have become due and payable, and thereafter until the Company's obligation with respect to the payment of said principal shall have been discharged as provided in the Indenture. Except as otherwise specifically provided in this Supplemental Indenture, the principal of and interest on the bonds of 1990 Series E shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, The State of New York in any coin or currency of the United States of America which at the time of payment is legal tender for public and private debts.

Each bond of 1990 Series E shall be dated the date of its authentication and interest shall be payable on the principal represented thereby from the March 31 or September 30 next preceding the date thereof to which interest has been paid on bonds of 1990 Series E, unless the bond is authenticated on a date to which interest has been paid, in which case interest shall be payable from the date of authentication. The bonds of 1990 Series E in definitive form shall be, at the election of the Company, fully engraved or shall be lithographed or printed in authorized denominations as aforesaid and numbered 1 and upwards (with such further designation as may be appropriate and desirable to indicate by such designation the form, series and denomination of bonds of 1990 Series E).

Temporary bonds of 1990 Series E, if any, may be printed and may be issued in authorized denominations in substantially the form of definitive bonds of 1990 Series E, but without a recital of redemption prices and with such omissions, insertions and variations as may be appropriate for temporary bonds, all as may be determined by the Company. 34 31 Interest on any bond of 1990 Series E which is payable on any interest payment date and is punctually paid or duly provided for shall be paid to the person in whose name that bond, or any previous bond to the extent evidencing the same debt as that evidenced by that bond, is registered at the close of business on the regular record date for such interest, which regular record date shall be the fifteenth day of March or September as the case may be (whether or not a business day) next preceding such interest payment date. If the Company shall default in the payment of the interest due on any interest payment date on the principal represented by any bond of 1990 Series E, such defaulted interest shall forthwith cease to be payable to the registered holder of that bond on the relevant regular record date by virtue of his having been such holder, and such defaulted interest may be paid to the registered holder of that bond (or any bond or bonds of 1990 Series E issued upon transfer or exchange thereof) on the date of payment of such defaulted interest or, at the election of the Company, to the person in whose name that bond (or any bond or bonds of 1990 Series E issued upon transfer or exchange thereof) is registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of bonds of 1990 Series E not less than ten (10) days preceding such subsequent record date, which subsequent record date shall be at least five (5) days prior to the payment date of such defaulted interest.

The 1990 Series C Bond shall be redeemable prior to stated 1990 SERIES C BOND. maturity, at the election of the Company on any interest payment date, at redemption prices calculated in accordance with the formula set forth below on giving notice of such redemption by first class mail, postage prepaid, by or on behalf of the Company not more than ninety (90) days nor less than thirty (30) days prior to the date fixed for redemption to the registered holder of the 1990 Series C Bond. The optional redemption payment of each bond to be redeemed shall be equal to the present worth, on the date of redemption, of the remaining scheduled semi- annual payments of interest and annual retirement of principal of such bond, calculated as follows. Determine the present value of each scheduled semi-annual payment of interest and annual retirement of principal by dividing each payment by the Present Value Divisor (PVD), where: __________ PVD = (\/ 1.0 + I) (D) I = That annual interest rate (which has been adjusted for semi-annual compounding) for U.S. Treasury securities, with comparable maturities as set forth in the Federal Reserve statistical release, designated H.15 (519), or its successor, published at least 4 days but not more than 10 days prior to the optional redemption date. The rate shall be the "This Week" Rate for Treasury Constant Maturities. Straight line interpolate to 3 decimal places after rounding the prepayment period to the nearest month (1st-15th round down) to match the remaining term of the bond to be redeemed. D = Present value divisor for the preceding 6 month interest period (D equals 1.0 for the period preceding the first period, which is the period from the redemption date to the first scheduled payment date thereafter). Add the present value for all scheduled annual retirements of principal and semi-annual payments of interest to determine the sum to be paid upon redemption of each bond. If the optional redemption payment is greater than the principal outstanding as of the date of optional redemption, the prepayment results in a premium, plus in each case accrued interest to the date fixed for redemption. If the optional redemption payment is less than the principal outstanding as of the date of the optional redemption, the prepayment results in a discount which shall be deducted from the outstanding principal amount which otherwise would have been paid, plus in each case accrued interest to the date fixed for redemption. 43 40 Any partial redemption shall, as the principal portion of such redemption, be no less than $100,000. No redemption pursuant to this paragraph shall be credited to, or relieve the Company to any extent from its obligation to make the principal payments provided for in Section 1 hereof. On or before the first day of February or August in each year, commencing September 1 1990, the Company will deliver to the Trustee a treasurer's certificate, which shall be irrevocable, specifying the principal amount of bonds to be optionally redeemed and accrued interest on such bonds on the next ensuing March 31 or September 30, or the first business day thereafter, respectively. The Trustee shall, upon the receipt of the treasurer's certificate, cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner herein provided for. On or before noon of the business day preceding the day of prepayment, the Company will advise the Trustee of the applicable premium or discount applicable to such prepayment. Such notice having been duly given, the redemption of bonds of 1990 Series C shall be made upon the terms and in the manner and with the effect hereinabove provided for with respect to redemptions. A treasurer's certificate shall not be required if no bonds of a series are to be redeemed under this paragraph. EXCHANGE. SECTION 3. At the option of the holder, upon written request made at least forty-five (45) days prior to an interest payment date and subject to the terms of the Indenture and compliance with applicable securities laws, the 1990 Series C Bond shall be exchangeable, in whole but not in part, for bonds of 1990 Series F (as hereinafter described) in an aggregate principal amount equal to the aggregate amount of unpaid principal which shall remain outstanding on the 1990 Series C Bond as of the date of such exchange. Such exchange shall occur only on an interest payment date for the 1990 Series C Bond at the office of the Trustee in the Borough of Manhattan, The City of New York, The State of New York. The 1990 Series C Bond shall bear a legend stating that such bond has not been registered under the United States Securities Act of 1933, as amended (the "Act") and that as a consequence such bond may not be offered, sold or otherwise transferred, whether or not for consideration, unless registered under such Act or pursuant to an exemption from such registration applicable to such offer, sale or other transfer, and may bear such other legends as may be necessary to comply with any law or with any rules or regulations made pursuant thereto.

The holder of the 1990 Series C Bond, by its acceptance of and holding thereof, consents and agrees that bonds of any series may be issued which mature on a date or dates later than October 1, 2024 and also consents to the deletion from the first paragraph of Section 5 of Article II of the Indenture of the phrase "but in no event later than October 1, 2024."

The aggregate principal amount of bonds of 1990 Series F shall be limited to the principal amount of 1990 Series C Bond being exchanged, except as provided in Sections 7 and 13 of Article II of the Original Indenture with respect to exchanges and replacements of bonds. The bonds of 1990 Series F shall mature on March 31, 2014 and shall be issued in exchange for, and in an aggregate principal amount equal to the principal amount remaining outstanding on, the 1990 Series C Bond as of the date of such exchange. The bonds of 1990 Series F shall be issued as registered bonds without coupons in denominations of $10,000 and any multiple thereof, and shall bear interest, payable semi-annually on March 31 and September 30 of each year (commencing on the first March 31 or September 30 following the date of such exchange), at the rate of eight and 357/1000 per centum (8.357%) per annum until the principal shall have become due and payable, and thereafter until the Company's obligation with respect to the payment of said principal shall have been discharged as provided in the Indenture.

Each bond of 1990 Series F shall be dated the date of its authentication and interest shall be payable on the principal represented thereby from the March 31 or September 30 next preceding the date thereof to which interest has been paid on bonds of 1990 Series F, unless the bond is authenticated on a date to which interest has been paid, in which case interest shall be payable from the date of authentication. The bonds of 1990 Series F in definitive form shall be, at the election of the Company, fully engraved or shall be lithographed or printed in authorized denominations as aforesaid and numbered 1 and upwards (with such further designation as may be appropriate and desirable to indicate by such designation the form, series and denomination of bonds of 1990 Series F).

If the Company shall default in the payment of the interest due on any interest payment date on the principal represented by any bond of 1990 Series F, such defaulted interest shall forthwith cease to be payable to the registered holder of that bond on the relevant regular record date by virtue of his having been such holder, and such defaulted interest may be paid to the registered holder of that bond (or any bond or bonds of 1990 Series F issued upon transfer or exchange thereof) on the date of payment of such defaulted interest or, at the election of the Company, to the person in whose name that bond (or any bond or bonds of 1990 Series F issued upon transfer or exchange thereof) is registered on a subsequent record date established by notice given by mail by or on behalf of the Company to the holders of bonds of 1990 Series F not less than ten (10) days preceding such subsequent record date, which subsequent record date shall be at least five (5) days prior to the payment date of such defaulted interest.
