Each of the other terms used in this First Supplemental Indenture that is defined in the Indenture and not defined herein shall have the meaning assigned to it in the Indenture. ARTICLE 2. THE SERIES B DEBENTURES SECTION 2.01 Terms and Form of the Series B Debentures (a) The Series B Debentures shall be designated "Public Service Enterprise Group Incorporated Floating Rate Deferrable Interest Subordinated Debentures, Series B." The Series B Debentures and the Trustee's Certificate of Authentication shall be substantially in the form of Exhibit A attached hereto. The Series B Debentures shall initially be issued as global Debentures in accordance with the provisions of Section 2.12 of the Indenture with The Depository Trust Company as Depositary. The terms and provisions contained in the Series B Debentures shall constitute, and are hereby expressly made, a part of this First Supplemental Indenture. The Company and the Trustee, by their execution and delivery of this First Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. (b) The aggregate principal amount of Series B Debentures outstanding at any time may not exceed $154,640,000 except as provided in Section 2.09 of the Indenture. The Series B Debentures shall be authenticated and delivered from time to time upon delivery to the Trustee of the items specified in Section 2.04(d) of the Indenture. (c) The Stated Maturity Date of the Series B Debentures is June 30, 2028. (d) The interest rate of the Series B Debentures will be a floating rate per annum determined quarterly by reference to 3-Month LIBOR, determined as described herein, plus a margin of 1.22%. "3-Month LIBOR" means the London interbank offered rate for three-month U.S. dollar deposits and with respect to any Interest Period (as defined below) will be calculated by First Union National Bank or any successor appointed by the Company as Calculation Agent, as permitted by this First Supplemental Indenture (the "Calculation Agent") as follows: i. On the second Market Day (as defined below) preceding the commencement of such Interest Period (each, a "Determination Date"), 3-Month LIBOR will be determined on the basis of the offered rate for deposits of not less than U.S. $1,000,000 for a period of three months (the "Index Maturity"), commencing on such Market Day, which appears on the display designated as Page 3750 on the Dow Jones Markets Limited (or such other page as may replace Page 3750 on that service (or any successor service) for the purpose of displaying London interbank offered rates of major banks) ("Telerate Page 3750") as of 11:00 a.m., London time on such Market Day. If no such offered rate appears, 3-Month LIBOR with respect to such Interest Period will be determined as described in (ii) below. The term "Interest Period" means each period beginning on, and including, the date of original issuance and ending on, but excluding, the first Interest Payment Date (as defined below) , and each successive period, so beginning on an Interest Payment Date and so ending on, but excluding the next successive Interest Payment Date. ii. With respect to a Determination Date on which no such offered rate appears on Telerate Page 3750 as described in (i) above, 3-Month LIBOR shall be the arithmetic mean, expressed as a percentage, of the offered rates for deposits in U.S. dollars for the Index Maturity which appears on the display designated as "LIBO" on the Reuter Monitor Money Market Rates Service (or such other page as may replace the LIBO page on that service (or any successor service) for the purpose of displaying London interbank offered rates of major banks) ("Reuters Screen LIBO Page") as of 11:00 a.m., London time, on such Market Day. If, in turn, such rate is not displayed on the Reuters Screen LIBO Page at such time, the Calculation Agent will obtain from each of four reference banks in London selected by the Calculation Agent (the "Reference Banks") such bank's offered quotation (expressed as a percentage per annum) as of approximately 11:00 a.m., London time, on such Market Day for deposits in U.S. dollars for the Index Maturity to prime banks in the London interbank market. If two or more such quotations are provided as requested, then 3-Month LIBOR for such Market Day shall be the arithmetic mean of such quotations. If, in turn, fewer than two such quotations are provided as requested, then 3-Month LIBOR for such Market Day will be obtained from the preceding Market Day for which the Reuters Screen LIBO Page displayed an offered rate for deposits in U.S. dollars for the Index Maturity. iii. If on any Determination Date, the Calculation Agent is required but unable to determine 3-Month LIBOR in the manner provided in paragraphs (i) and (ii) above, 3-Month LIBOR for such Interest Period shall be 3-Month LIBOR as determined on the immediately preceding Determination Date. The term "Market Day" means any day on which commercial banks and foreign exchange markets are open for business (including dealings in foreign exchange and foreign currency deposits) in The City of New York and The City of London. The interest rate for any Interest Period will at no time be higher than the maximum rate then permitted by applicable law. All percentages resulting from any calculations referred to herein will be rounded, if necessary, to the nearest multiple of 1/100 of 1% and all U.S. dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent or more being rounded upwards). The Calculation Agent shall, as soon as practicable after 11:00 a.m., London time, on each Determination Date, determine the interest rate and calculate the amount of interest payable in respect of the Interest Period related to such Determination Date (the "Interest Amount"). The Interest Amount shall be calculated by applying the interest rate to the principal amount of each Series B Debenture outstanding at the commencement of the Interest Period, multiplying such amount by the actual number of days in the applicable Interest Period divided by 360 and rounding the resultant figure to the nearest cent (with one-half cent or more being rounded upwards). The determination of the interest rate and the Interest Amount by the Calculation Agent will (in the absence of willful default, bad faith or manifest error) be final, conclusive and binding on all concerned. Neither the Calculation Agent nor the Company (or any of their respective officers, directors, agents, beneficiaries, employees or affiliates) shall have any liability to any person for (i) the selection of any Reference Bank or (ii) any inability to retain major banks in the London interbank market, in the case of the Calculation Agent, which is caused by circumstances beyond its reasonable control. All certificates, communications, opinions, determinations, calculations, quotations and decisions given, expressed, made or obtained for the purposes of the provisions hereof relating to the payment and calculation of interest on the Series B Debentures, whether by the Reference Banks (or any of them) or the Calculation Agent, will (in the absence of willful default, bad faith or manifest error) be binding on Trust II, the Company, the Trustee, the Calculation Agent and all of the holders of the Series B Debentures and no liability will (in the absence of willful default, bad faith or manifest error) attach to the Calculation Agent in connection with the exercise or non-exercise by it of its powers, duties and discretion. (e) The "Interest Payment Dates" for the Series B Debentures are March 31, June 30, September 30 and December 31 of each year, commencing September 30, 1998. In the event that any date on which interest is payable on the Series B Debentures is not a Business Day, then payment of interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The Regular Record Date for each Interest Payment Date for the Series B Debentures shall be the 15th day (whether or not a Business Day) of the last month of each quarter, provided that if Trust II is the sole Holder of the Series B Debentures or the Series B Debentures are issued in book-entry-only form, the Regular Record Date shall be the close of business on the Business Day next preceding such Interest Payment Date. Each Series B Debenture shall bear interest from its Issue Date or from the most recent Interest Payment Date to which interest has been paid or duly provided for with respect to such Series B Debenture; except that, so long as there is no existing Defaulted Interest or Extension Period on the Series B Debentures, any Series B Debenture authenticated by the Trustee between the Regular Record Date for any Interest Payment Date and such Interest Payment Date shall bear interest from such Interest Payment Date. Overdue principal of, and interest on, any Series B Debenture and interest which has been deferred pursuant to Section 4.01(b) of the Indenture shall bear interest (to the extent that the payment of such interest shall be legally enforceable) at a rate per annum equal to the interest rate per annum payable on such Series B Debenture. The Calculation Agent will cause the interest rate, the Interest Amount in respect of each Series B Debenture and the interest payment date for each Interest Period to be given to the Trustee, the Property Trustee and the Company as soon as practicable after the determination thereof but in no event later than the second Business Day of the applicable Interest Period. (f) The Series B Debentures shall be issuable only in registered form without coupons and only in denominations of $1,000 and any integral multiple thereof. (g) The maximum Extension Period for the Series B Debentures shall be 20 consecutive quarters. (h) First Union National Bank shall initially be the Paying Agent for the Series B Debentures. (i) First Union National Bank shall initially be the Calculation Agent for the Series B Debenture. In the event of the resignation or removal of First Union National Bank as the Calculation Agent, the Company will promptly appoint a successor Calculation Agent and such successor Calculation Agent shall, without any further act, deed or conveyance become vested with all of the authority, rights, duties and obligations of the Calculation Agent with the like effect as if originally appointed as Calculation Agent. ARTICLE 3. REDEMPTION SECTION 3.01 Redemption; Notice to Trustee (a) The Series B Debentures are subject to redemption prior to maturity as provided therein. (b) Any redemption of the Series B Debentures shall be made in the manner, upon the terms and with the effect, all as provided in Sections 3.01(c), 3.02, 3.03, 3.04, 3.05 and 3.06 of the Indenture.

The amount of interest payable on any Interest Payment Date shall be calculated by applying the interest rate to the principal amount outstanding at the commencement of the Interest Period, multiplying such amount by the actual number of days in the applicable Interest Period divided by 360 and rounding the resultant figure to the nearest cent (with one-half cent or more being rounded upwards). In the event that any Interest Payment Date is not a Business Day, then interest will be payable on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such date. The interest installment so payable, and punctually paid or duly provided for as provided in the Indenture, shall be paid to the Person in whose name this Debenture is registered at the close of business on the Regular Record Date for such interest installment, which shall be the 15th day (whether or not a Business Day) of the last month of each quarter, provided that if all of the Series B Debentures (as defined below) are then held by Enterprise Capital Trust II (the "Trust") or the Series B Debentures are held in book-entry-only form, the Regular Record Date shall be the close of business on the Business Day next preceding such Interest Payment Date. Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the Holders on such Regular Record Date, and may be paid to the Person in whose name this Debenture is registered at the close of business on a Special Record Date to be fixed by the Trustee (as defined below) for the payment of such defaulted interest, notice whereof shall be given to the Holders of the Series B Debentures not less than 7 days prior to such Special Record Date, as more fully provided in the Indenture. Payment of the principal of and interest on this Debenture will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of interest on an Interest Payment Date will be made by check mailed to the Holder hereof at the address shown in the Register or, at the option of the Holder hereof, to such other place in the United States of America as Holder hereof shall designate to the Trustee in writing. At the request of a Holder of at least $10,000,000 aggregate principal amount of Series B Debentures, interest on such Debentures will be payable by wire transfer within the continental United States in immediately available funds to the bank account number specified in writing by such Holder to the Registrar prior to the Regular Record Date.

The indebtedness evidenced by this Debenture is, to the extent provided in the Indenture, subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. The Holder of this Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. The Holder of this Debenture, by his acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions. This Debenture is one of a duly authorized series of Debentures of the Company (herein sometimes referred to as the "Series B Debentures"), specified in the Indenture, limited in aggregate principal amount to One Hundred Fifty-Four Million, Six Hundred Forty Thousand Dollars ($154,640,000) issued under and pursuant to an Indenture dated as of January 1, 1998 executed and delivered between the Company and First Union National Bank, as trustee (the "Trustee"), as supplemented by the First Supplemental Indenture dated as of June 1, 1998 between the Company and the Trustee (said Indenture as so supplemented being hereinafter referred to as the "Indenture"). The Series B Debentures are initially being issued to the Trust, to be held on behalf of the Trust by its property trustee (the "Property Trustee"). Concurrently with the issuance of the Series B Debentures, the Trust is issuing its trust securities, representing undivided beneficial interests in the assets of the Trust and having an aggregate liquidation amount equal to the principal amount of the Series B Debentures, including the Trust's Floating Rate Capital Securities, Series B (the "Preferred Securities"). By the terms of the Indenture, Debentures are issuable in series which may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Indenture. Reference is made to the Indenture and all indentures supplemental thereto for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Debentures. Each term used in this Debenture which is defined in the Indenture and not defined herein shall have the meaning assigned to it in the Indenture. The following redemption provisions shall apply to the Series B Debentures: Regular Redemption The Series B Debentures may be redeemed in whole or part at the option of the Company at any time on or after June 30, 2003 at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest to the redemption date. Special Event Redemption If a Tax Event or an Investment Company Event (each, a "Special Event") has occurred and is continuing, the Company may redeem the Series B Debentures, in whole but not in part, at a price equal to 100% of the principal amount thereof plus accrued and unpaid interest to the redemption date within 90 days following the occurrence of such Special Event. "Tax Event" means that the Company shall have received an opinion of counsel (which may be counsel to the Company or an affiliate but not an employee thereof and which must be acceptable to the Property Trustee) experienced in such matters to the effect that, as a result of any amendment to, or change (including any announced prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein affecting taxation, or as a result of any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or such pronouncement or decision is announced on or after the date of original issuance of the Series B Capital Securities, there is more than an insubstantial risk that (i) the Trust is, or will be, subject to federal income tax with respect to interest on the Series B Debentures, (ii) interest payable by the Company on the Series B Debentures is not, or will not be, deductible by the Company for federal income tax purposes or (iii) the Trust is, or will be, subject to more than a de minimis amount of other taxes, duties, assessments or other governmental charges. "Investment Company Event" means the occurrence of a change in law or regulation or a change in interpretation or application of law or regulation by any legislative body, court, governmental agency or regulatory authority (a "Change in 1940 Act Law") to the effect that the Trust is or will be considered an "investment company" that is required to be registered under the Investment Company Act of 1940, as amended, which Change in 1940 Act Law becomes effective on or after the date of original issuance of the Series B Capital Securities. At least 30 days but not more than 60 days before the Redemption Date, the Trustee shall mail or caused to be mailed a notice of redemption by first-class mail, postage prepaid, to each Holder of Series B Debentures to be redeemed. In the event of redemption of this Debenture in part only, a new Series B Debenture or Debentures for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. In case an Event of Default with respect to the Series B Debentures occurs and is continuing, the principal of and interest on all of the Series B Debentures may (and, in certain circumstances shall) be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture. The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Debenture upon compliance by the Company with certain conditions set forth therein. Subject to certain exceptions in the Indenture which require the consent of every Holder, the Company and the Trustee may amend the Indenture or may waive future compliance by the Company with any provisions of the Indenture with the consent of the Holders of at least a majority in aggregate principal amount of the Debentures of each series affected thereby provided that if the Series B Debentures are held by the Trust, no such amendment or waiver that adversely affects the holders of the Preferred Securities shall be effective without the prior consent of the holders of at least a majority in aggregate liquidation amount of the outstanding Preferred Securities issued under the Indenture at the time outstanding. Subject to certain exceptions in the Indenture, without the consent of any Holder of the Debentures issued under the Indenture, the Company and the Trustee may amend the Indenture to cure any ambiguity, defect or inconsistency, to bind a successor to the obligations of the Indenture, to provide for uncertificated Debentures in addition to certificated Debentures, to comply with any requirements of the Debentures and the Securities and Exchange Commission in connection with the qualification of the Indenture under the TIA, or to make any change that, in the reasonable judgment of the Company, does not adversely affect the rights of any Holder of the Debentures. Amendments bind all Holders and subsequent Holders of Debentures. No reference herein to the Indenture and no provision of this Debenture or the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Debenture at the time and place and at the rate and in the money herein prescribed. So long as an Event of Default with respect to the Series B Debentures has not occurred and is continuing, the Company shall have the right at any time and from time to time to extend the interest payment period of the Series B Debentures for up to 20 consecutive quarters (the "Extension Period"), provided that no Extension Period shall extend beyond the Stated Maturity Date or Redemption Date of any Series B Debenture. At the end of the Extension Period, the Company shall pay all interest then accrued and unpaid (together with interest thereon at the rate specified on a quarterly basis for the Series B Debentures, as described in the Indenture, compounded quarterly, to the extent that payment of such interest is enforceable under applicable law). During such Extension Period, the Company may not declare or pay any dividend on, redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock. Prior to the termination of any such Extension Period, the Company may further extend such Extension Period, provided that such Extended Interest Payment Period together with all such previous and further extensions thereof shall not exceed 20 consecutive quarters and shall not extend beyond the Stated Maturity Date or Redemption Date of any Series B Debenture. At the termination of any such Extended Interest Payment Period and upon the payment of all amounts then due, the Company may elect to begin a new Extended Interest Payment Period, subject to the foregoing restrictions. Series B Debentures are issuable only in registered form without coupons in denominations of $1,000 and any integral multiple thereof. As provided in the Indenture and subject to certain limitations therein set forth, this Debenture is exchangeable for a like aggregate principal amount of Series B Debentures of a different authorized denomination, as requested by the Holder surrendering the same. As provided in the Indenture and subject to certain limitations therein set forth, this Debenture is transferable by the Holder hereof upon surrender of this Debenture for registration of transfer at the office or agency of the Registrar accompanied by a written instrument or instruments of transfer in form satisfactory to the Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Series B Debentures of authorized denominations and for the same aggregate principal amount will be issued to the designated transferee or transferees. No service charge will be made for any such transfer, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in relation thereto. Prior to presentment for registration of transfer of this Debenture, the Company, the Trustee, any Paying Agent and any Registrar may deem and treat the Holder hereof as the absolute owner hereof (whether or not this Debenture shall be overdue and notwithstanding any notice of ownership or writing hereon made by anyone other than the Registrar) for the purpose of receiving payment of or on account of the principal hereof and interest due hereon and for all other purposes, and neither the Company nor the Trustee nor any Paying Agent nor any Registrar shall be affected by any notice to the contrary.
