SECTION 2.7. RESTRICTIONS ON TRANSFER AND EXCHANGE OF INITIAL BONDS. (a) Initial Bonds in definitive form, all Rule 144A Global Bonds and all beneficial interests in one or more Rule 144A Global Bonds, and all Bonds (other than Exchange Bonds or Bonds sold pursuant to an effective registration statement) issued upon registration of transfer of, or in exchange for, any such Bonds, shall be restricted securities (within the meaning of Rule 144 under the Securities Act; hereinafter, collectively, "RESTRICTED SECURITIES") and shall be subject to the restrictions on transfer provided in the legend set forth on the Restricted Securities. The Holder of each Restricted Security, by such Holder's acceptance thereof, agrees to be bound by such restrictions on transfer. All Restricted Securities shall bear the legend set forth on the face of the Restricted Securities. Institutional Accredited Investors that are not QIBs may hold interests in the Initial Bonds only in definitive form. Any beneficial interest in a Global Bond that is a Restricted Security and is transferred to an Institutional Accredited Investor which is not a QIB will be delivered in the form of a definitive Bond and will cease to be an interest in such Global Bond. A holder of a beneficial interest in a Global Bond may exchange such beneficial interest for one or more definitive Bonds if (i) the Issuer notifies the Trustee in writing that the Registered Depositary is unwilling or unable to continue as depositary for such Global Bond, or the Registered Depositary ceases to be a "Clearing Agency" registered under the Exchange Act and a successor depositary is not appointed by the Issuer within 90 days of such notice or cessation or (ii) the Issuer, at its option, notifies the Trustee in writing that it elects to cause the issuance of definitive Bonds. If an exchange of a Global Bond for a definitive Bond is made pursuant to clauses (i) or (ii) above, then, upon surrender by the Registered Depositary of any beneficial interest in the Global Bonds, definitive Bonds will be issued to each person that the Registered Depositary identifies as the beneficial owner of the Bonds represented by the Global Bonds. Upon any such issuance, the Trustee will be required to register such definitive Bonds in the name of such person or persons (or nominee of any thereof) and cause the same to be delivered thereto. Unless determined otherwise by the Issuer in accordance with applicable law, each such Rule 144A Global Bond and all definitive Bonds, upon transfer or exchange of Northeast Generation Supplemental Indenture ------------------------------------------- <Page> -14- beneficial interests in a Rule 144A Global Bond (other than for an Exchange Bond) will bear the legend set forth on the face of the Restricted Securities. Each Holder of a definitive Bond or a beneficial interest in a Global Bond that is a Restricted Security will be deemed to have represented and agreed to offer, sell, pledge or otherwise transfer such Bonds or beneficial interest only in accordance with the legend set forth on the face of the Restricted Securities. Upon the transfer, exchange or replacement of definitive Bonds bearing the legend, or upon request for removal of the legend on a definitive Bond, the Trustee will deliver Bonds that do not bear such legend if the Trustee has been provided evidence satisfactory to the Issuer (which may include an opinion of counsel) that neither the legend nor the restrictions on transfer set forth therein are required to ensure compliance with the Securities Act. Subject to the restrictions on transfer and exchange set forth herein and in the Original Indenture, the holder of any Bond may transfer or exchange such Bond in whole or in part (in a principal amount equal to the minimum authorized denomination or any greater amount which is an integral multiple of $1,000 or a lesser amount if the holder is transferring or exchanging all of the Bonds held by such holder) by surrendering it at the Corporate Trust Office of the Trustee or at the office of the transfer agent, together with (a) an executed instrument of assignment and transfer substantially in the form set forth in Exhibit C to this First Supplemental Indenture (in the case of a transfer) or a written request for exchange (in the case of exchange) and (b) additional certifications and evidence that such transfer or exchange is in compliance with the Securities Act and the restrictions on transfer set forth in such Bond as may be required pursuant to the terms of this First Supplemental Indenture. Upon surrender of a definitive Bond for transfer or exchange with the appropriate documentation, or notification of a request for transfer or exchange of a beneficial interest in a Global Bond for a definitive Bond or Bonds, subject to the restrictions described herein and in the Original Indenture, the Trustee will, within five Business Days of such request if made at the Corporate Trust Office of the Trustee, or within 10 Business Days if made at the office of a transfer agent (other than the Trustee), authenticate and deliver at the Corporate Trust Office of the Trustee or the office of the transfer agent, as the case may be, to the transferee (in the case of transfer) or Holder (in the case of exchange) or send by first class mail at the risk of the transferee (in the case of transfer) or Holder (in the case of exchange) to such address as the transferee or Holder, as applicable, may request, a definitive Bond or Bonds, as the case may require, for a like aggregate principal amount and in such authorized denomination or denominations as may be requested. The presentation for transfer or exchange of any definitive Bond will not be valid unless made at the Corporate Trust Office of the Trustee or at the office of a transfer agent by the registered holder in person or by a duly authorized attorney-in-fact. The Security Registrar is not required (a) to issue, register the transfer of or exchange any Initial Bonds of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Bonds of such series selected for redemption and ending at the close of business on the day of such mailing or (b) to issue, register the transfer of or exchange any Initial Bond selected for redemption in whole or in part except the unredeemed Northeast Generation Supplemental Indenture ------------------------------------------- <Page> -15- portion of any Initial Bond selected for redemption in part.

During the Distribution Compliance Period, interests in the Regulation S Global Bond, if any, may be exchanged for interests in the Rule 144A Global Bond or for definitive bonds only in accordance with the certification requirements described in this Section 2.7. After the expiration of the Distribution Compliance Period, interests in the Regulation S Global Bond may be transferred without requiring the certification set forth in Exhibit E annexed hereto or any additional certification. As used in the preceding two paragraphs of this Section 2.7, the term "transfer" encompasses any sale, transfer or other disposition of any Bonds referred to herein except for transfers from any Holder to an Affiliate of such Holder; PROVIDED, that such transferring Holder shall deliver a letter to the Trustee stating that the transferee is an Affiliate of such Holder. The Trustee shall be entitled to rely on and be fully protected in its reliance on such letter. ARTICLE III APPLICATION OF PROCEEDS FROM SALE OF BONDS SECTION 3.1.

The Issuer hereby establishes at the Trustee's Corporate Trust Office a special, segregated and irrevocable collateral account (the "DEBT SERVICE RESERVE ACCOUNT") which shall be maintained at all times until none of the Bonds of the series of Bonds created by this First Supplemental Indenture remain outstanding. All amounts from time to time held in the Debt Service Reserve Account shall be held in the name of the Trustee for the benefit of the Holders. Except as expressly provided in this First Supplemental Indenture, the Issuer shall not have any right to withdraw funds from the Debt Service Reserve Account.
