                         and the final maturity date of the series bears to the
                         number of semi-annual payment dates between December 31,
                         1994 and the final maturity date, plus in each case accrued
                         interest to the date fixed for redemption. 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 amount of bonds to be optionally
                         redeemed and the corresponding premium, if any, 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. Such notice
                         having been duly given, the redemption of bonds of 1990
                         Series A 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 to both the Company and the Trustee made at least
                         forty-five (45) days prior to an interest payment date and

                         applicable securities laws, the 1990 Series A Bond shall be
                         exchangeable, in whole but not in part, for bonds of 1990

                         A Bond as of the date of such exchange. Such exchange shall
                         occur only on an interest payment date for the 1990 Series A
                         Bond at the office of the Trustee in the Borough of

                         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

                                          [FORM OF REVERSE OF BOND]

                           This bond is the only bond of an authorized issue of bonds
                         of the Company, unlimited as to amount except as provided in
                         the Indenture hereinafter mentioned or any indentures
                         supplemental thereto, and is one of a series of said bonds
                         known as General and Refunding Mortgage Bonds, 1990 Series A

                         except as otherwise provided in the Indenture hereinafter
                         mentioned. This bond is issued and to be issued under, and
                         is equally and ratably secured (except insofar as any
                         sinking, amortization, improvement or analogous fund,
                         established in accordance with the provisions of the
                         Indenture hereinafter mentioned, may afford additional
                         security for the bonds of any particular series and except
                         as provided in Section 3 of Article VI of said Indenture) by
                         an Indenture, dated as of October 1, 1924, duly executed by
                         the Company to Bankers Trust Company, a corporation of the
                         State of New York, as Trustee, to which Indenture and all
                         indentures supplemental thereto (including the Supplemental
                         Indenture dated as of February 15, 1990) reference is hereby
                         made for a description of the properties and franchises
                         mortgaged and conveyed, the nature and extent of the
                         security, the terms and conditions upon which the bonds are
                         issued and under which additional bonds may be issued, and
                         the rights of the holders of the bonds and of the Trustee in
                         respect of such security (which Indenture and all indentures
                         supplemental thereto, including the Supplemental Indenture
                         dated as of February 15, 1990, are hereinafter collectively
                         called the "Indenture"). 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 A 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." Such holder further agrees that (a) such consent
                         shall, for all purposes of Article XV of the Indenture and
                         without further action on the part of such holder, be deemed
                         the affirmative vote of such holder at any meeting called
                         pursuant to said Article XV for the purpose of approving
                         such deletion, and (b) such deletion shall become effective
                         at such time as not less than eighty-five percent (85%) in
                         principal amount of bonds outstanding under the Indenture
                         shall have consented thereto substantially in the manner set

                           This bond shall be redeemable prior to stated 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 A Bond.

                           Any such redemption payment shall be equal to one hundred
                         percent (100%) of the principal so redeemed, plus a
                         prepayment premium, if any, in an amount equal to one
                         hundred percent (100%) of the amount of interest for one
                         year on the unpaid principal balance proposed to be
                         redeemed, multiplied by the ratio which the number of semi-
                         annual payment dates between the proposed redemption date
                         and the final maturity date of the series bears to the
                         number of semi-annual payment dates between December 31,
                         1994 and the final maturity date, plus in each case accrued
                         interest to the date fixed for redemption. 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 above.

                         hereon or otherwise in respect hereof or of the Indenture,

                         been paid on bonds of 1990 Series D, unless the bond is
                         authenticated on a date to which interest has been paid, in

                         authentication.

                           The bonds of 1990 Series D in definitive form shall be, at
                         the election of the Company, fully engraved or shall be

                         reference is hereby made for a description of the properties
                         and franchises mortgaged and conveyed, the nature and extent
                         of the security, the terms and conditions upon which the
                         bonds are issued and under which additional bonds may be
                         issued, and the rights of the holders of the bonds and of
                         the Trustee in respect of such security (which Indenture and

                         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

                         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

                         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 holders of the bonds of 1990 Series D, by their
                         acceptance of and holding thereof, consent and agree that
                         bonds of any series may be issued which mature on a date or
                         dates later than October 1, 2024 and also consent to the

                         October 1, 2024,". Such holders further agree that (a) such
                         consent shall, for all purposes of Article XV of the
                         Indenture and without further action on the part of such
                         holders, be deemed the affirmative vote of such holders at
                         any meeting called pursuant to said Article XV for the
                         purpose of approving such deletion, and (b) such deletion
                         shall become effective at such time as not less than
                         eighty-five percent (85%) in principal amount of bonds
                         outstanding under the Indenture shall have consented thereto
                         substantially in the manner set forth in Section 3 of Part I
                         of the Supplemental Indenture dated as of February 15, 1990,

                         called pursuant to said Article XV, or by any combination
                         thereof.

                           Payments of principal, premium, if any, and interest on
                         the 1990 Series B Bond shall be made by bank wire transfer
                         in immediately available funds in lawful money of the United
                         States of America to the bank account of the registered
                         holder of such bond which such registered holder shall
                         designate in writing to Bankers Trust Company, Trustee, not
                         less than fifteen (15) days prior to the date such payment
                         shall become due and payable.

                           When a semi-annual interest payment date falls on a
                         Saturday, Sunday or a day on which the Federal Reserve Bank
                         of New York or the Trustee is not open for business, all
                         payments shall be payable on the first day thereafter on
                         which the Federal Reserve Bank of New York and the Trustee
                         are open for business.

                           In the event any semi-annual payment is not made when due,
                         the amount payable shall be such payment, plus interest
                         thereon at the interest rate on such bond, based on a
                         360-day year, from the due date to the date of payment.

                           The 1990 Series B Bond shall be dated January 3, 1990 and
                         interest shall be payable from January 3, 1990.

                           The 1990 Series B Bond in definitive form shall be, at the
                         election of the Company, fully engraved or shall be
                         lithographed or printed.

                           The 1990 Series B Bond shall not be subject to or entitled
                         to any sinking fund.

REDEMPTION OF              SECTION 2. The 1990 Series B Bond shall be redeemable
1990 SERIES B BOND.      prior to stated 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 B 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 = (FYYY
                           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.

                                        24

                      
                                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.

                           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 B 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 B Bond shall be exchangeable, in whole but
                         not in part, for bonds of 1990 Series E (as hereinafter
                         described) in an aggregate principal amount equal to the
                         aggregate amount of unpaid principal which shall remain
                         outstanding on the 1990 Series B Bond as of the date of such
                         exchange. Such exchange shall occur only on an interest
                         payment date for the 1990 Series B 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 B 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.

CONSENT.                   SECTION 4. The holder of the 1990 Series B Bond, by its

                         except as otherwise provided in the Indenture hereinafter
                         mentioned. This bond is issued and to be issued under, and
                         is equally and ratably secured (except insofar as any
                         sinking, amortization, improvement or analogous fund,
                         established in accordance with the provisions of the
                         Indenture hereinafter mentioned, may afford additional

                         as provided in Section 3 of Article VI of said Indenture) by
                         an Indenture, dated as of October 1, 1924, duly executed by
                         the Company to Bankers Trust Company, a corporation of the
                         State of New York, as Trustee, to which Indenture and all
                         indentures supplemental thereto (including the Supplemental
                         Indenture dated as of February 15, 1990) reference is hereby
                         made for a description of the properties and franchises
                         mortgaged and conveyed, the nature and extent of the
                         security, the terms and conditions upon which the bonds are
                         issued and under which additional bonds may be issued, and
                         the rights of the holders of the bonds and of the Trustee in
                         respect of such security (which Indenture and all indentures
                         supplemental thereto, including the Supplemental Indenture
                         dated as of February 15, 1990, are hereinafter collectively
                         called the "Indenture"). 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." Such holder further agrees that (a) such consent
                         shall, for all purposes of Article XV of the Indenture and
                         without further action on the part of such holder, be deemed
                         the affirmative vote of such holder at any meeting called
                         pursuant to said Article XV for the purpose of approving
                         such deletion, and (b) such deletion shall become effective
                         at such time as not less than eighty-five percent (85%) in
                         principal amount of bonds outstanding under the Indenture
                         shall have consented thereto substantially in the manner set
                         forth in Section 3 of Part I of the Supplemental Indenture
                         dated as of February 15, 1990, or in writing, or by

                         Article XV, or by any combination thereof.

                           This bond shall be redeemable prior to stated maturity, at
                         the election of the Company on any interest payment date, at
                         the redemption prices calculated in accordance with the

                         Company not more than ninety (90) days nor less than thirty
                         (30) days prior to the date fixed for redemption to the

                           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 = (FYYY
                           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

                         1990 Series E"). 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

                         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

                         (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. The interest
                         on bonds of 1990 Series E, whether in temporary or
                         definitive form, shall be payable without presentation of
                         such bonds and (subject to the provisions of this Section 1)
                         only to or upon the written order of the registered holders
                         thereof.

                           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). Until bonds of 1990 Series E in
                         definitive form are ready for delivery, the Company may
                         execute, and upon its request in writing the Trustee shall
                         authenticate and deliver in lieu thereof, bonds of 1990
                         Series E in temporary form, as provided in Section 10 of
                         Article II of the Indenture. 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.

                           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

                         respects by affirmative vote of at least eighty-five percent
                         (85%) in principal amount of the bonds then outstanding,

                         proposed to be taken, then also by affirmative vote of at

                         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 holders of the bonds of 1990 Series E, by their
                         acceptance of and holding thereof, consent and agree that

                         consent shall, for all purposes of Article XV of the
                         Indenture and without further action on the part of such
                         holders, be deemed the affirmative vote of such holders at
                         any meeting called pursuant to said Article XV for the
                         purpose of approving such deletion, and (b) such deletion
                         shall become effective at such time as not less than
                         eighty-five percent (85%) in principal amount of bonds

                         of the Supplemental Indenture dated as of February 15, 1990,

                         called pursuant to said Article XV, or by any combination
                         thereof.

                           When a semi-annual interest payment date falls on a
                         Saturday, Sunday or a day on which the Federal Reserve Bank
                         of New York or the Trustee is not open for business, all
                         payments shall be payable on the first day thereafter on
                         which the Federal Reserve Bank of New York and the Trustee
                         are open for business.

                           In the event any semi-annual payment is not made when due,
                         the amount payable shall be such payment, plus interest
                         thereon at the interest rate of one and one-half times the
                         rate to be determined by the Secretary of the Treasury
                         taking into consideration the prevailing market yield on the
                         remaining maturity of the most recently auctioned 13-week
                         U.S. Treasury bills, from the due date to the date of
                         payment. Upon the expiration of each successive 91-day
                         period following the scheduled payment date for any
                         outstanding payment, a new rate shall be established
                         pursuant to this paragraph and such rate shall be applied to
                         the outstanding payment and all late charges accrued
                         thereon.

                           The 1990 Series C Bond shall be dated January 3, 1990 and
                         interest shall be payable from January 3, 1990.

                           The 1990 Series C Bond in definitive form shall be, at the
                         election of the Company, fully engraved or shall be
                         lithographed or printed.

                           The 1990 Series C Bond shall not be subject to or entitled
                         to any sinking fund.

REDEMPTION OF              SECTION 2. The 1990 Series C Bond shall be redeemable
1990 SERIES C BOND.      prior to stated 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 = (FYYY
                           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.

   44
                                        41

                      
                                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.

                           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.

CONSENT.                   SECTION 4. 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." Such holder further agrees that (a) such
                         consent shall, for all purposes of Article XV of the

                         date to which interest has been paid hereon, until the

                         principal shall have been discharged, all as provided, to

                         Indenture hereinafter mentioned on the reverse hereof and in

                         the amount payable shall be such payment, plus interest
                         thereon at the interest rate of one and one-half times the
                         rate to be determined by the Secretary of the Treasury
                         taking into consideration the prevailing market yield on the

                         U.S. Treasury bills, from the due date to the date of
                         payment. Upon the expiration of each successive 91-day
                         period following the scheduled payment date for any
                         outstanding payment, a new rate shall be established
                         pursuant to this paragraph and such rate shall be applied to
                         the outstanding payment and all late charges accrued
                         thereon.

                           When any payment date falls on a Saturday, Sunday or a day
                         on which the Federal Reserve Bank of New York or the Trustee
                         is not open for business, all payments shall be payable on
                         the first day thereafter on which the Federal Reserve Bank
                         of New York and the Trustee are open for business.

                           At the written request of the registered holder hereof
                         made at least forty-five (45) days in advance of an interest
                         payment date, this bond shall be exchangeable, in whole but
                         not in part, on any interest payment date in an aggregate
                         principal amount equal to the amount of unpaid principal
                         which shall remain outstanding on this bond as of the date
                         of such exchange (after giving effect to the payment of
                         principal hereon on the date of such exchange), all as
                         provided, to the extent and in the manner specified in the
                         Indenture and the Supplemental Indenture hereinafter
                         mentioned on the reverse hereof.

                                          [FORM OF REVERSE OF BOND]

                         of the Company, unlimited as to amount except as provided in

                         except as otherwise provided in the Indenture hereinafter
                         mentioned. This bond is issued and to be issued under, and
                         is equally and ratably secured (except insofar as any
                         sinking, amortization, improvement or analogous fund,
                         established in accordance with the provisions of the
                         Indenture hereinafter mentioned, may afford additional

                         as provided in Section 3 of Article VI of said Indenture) by
                         an Indenture, dated as of October 1, 1924, duly executed by
                         the Company to Bankers Trust Company, a corporation of the
                         State of New York, as Trustee, to which Indenture and all
                         indentures supplemental thereto (including the Supplemental
                         Indenture dated as of February 15, 1990) reference is hereby
                         made for a description of the properties and franchises
                         mortgaged and conveyed, the nature and extent of the
                         security, the terms and conditions upon which the bonds are
                         issued and under which additional bonds may be issued, and
                         the rights of the holders of the bonds and of the Trustee in
                         respect of such security (which Indenture and all indentures
                         supplemental thereto, including the Supplemental Indenture
                         dated as of February 15, 1990, are hereinafter collectively
                         called the "Indenture"). 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 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." Such holder further agrees that (a) such consent
                         shall, for all purposes of Article XV of the Indenture and
                         without further action on the part of such holder, be deemed
                         the affirmative vote of such holder at any meeting called
                         pursuant to said Article XV for the purpose of approving
                         such deletion, and (b) such deletion shall become effective
                         at such time as not less than eighty-five percent (85%) in
                         principal amount of bonds outstanding under the Indenture
                         shall have consented thereto substantially in the manner set
                         forth in Section 3 of Part I of the Supplemental Indenture
                         dated as of February 15, 1990, or in writing, or by
                         affirmative vote cast at a meeting called pursuant to said
                         Article XV, or by any combination thereof.

                           This bond shall be redeemable prior to stated maturity, at
                         the election of the Company on any interest payment date, at
                         the 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 = (FYYY
                           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

                         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.

                         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

                         (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. Except as otherwise specifically provided in this
                         Supplemental Indenture, the principal of and interest on the
                         bonds of 1990 Series F 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. The interest
                         on bonds of 1990 Series F, whether in temporary or
                         definitive form, shall be payable without presentation of
                         such bonds and (subject to the provisions of this Section 1)
                         only to or upon the written order of the registered holders
                         thereof.

                           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). Until bonds of 1990 Series F in
                         definitive form are ready for delivery, the Company may
                         execute, and upon its request in writing the Trustee shall
                         authenticate and deliver in lieu thereof, bonds of 1990
                         Series F in temporary form, as provided in Section 10 of
                         Article II of the Indenture. Temporary bonds of 1990 Series
                         F, if any, may be printed and may be issued in authorized
                         denominations in substantially the form of definitive bonds
                         of 1990 Series F, 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.

                           Interest on any bond of 1990 Series F 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 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

                         (85%) in principal amount of the bonds then outstanding,

                         is unconditional.

                           The holders of the bonds of 1990 Series F, by their
                         acceptance of and holding thereof, consent and agree that

                         holders, be deemed the affirmative vote of such holders at
                         any meeting called pursuant to said Article XV for the
                         purpose of approving such deletion, and (b) such deletion
                         shall become effective at such time as not less than
