No service charge shall be made for the registration of transfer or exchange of the Senior Notes of the Third and Fourth Series; provided, however, that the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with the exchange or transfer. 16. Additional Amounts. All payments of principal and interest ------------------ (including Additional Interest, as defined in the Registration Rights Agreement, and payments of discount and premium, if any) with respect to the Senior Notes of the Third and Fourth Series and all payments made pursuant to the Guarantee shall be made free and clear of, and without withholding or deduction for or on account of, any present or future taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or within any supranational federation to which a Jurisdiction of Incorporation belongs or any Jurisdiction of Incorporation (or any political subdivision or taxing authority thereof or therein) or any jurisdiction in which the Company or the Guarantor is managed or has a place of business (each, a "Taxing Jurisdiction") or by or within any political subdivision thereof or any authority therein or thereof having power to tax, unless such withholding or deduction is required by law. In the event of any such withholding or deduction ("Gross-Up Taxes"), the Company or the Guarantor, as the case may be, shall pay to the Holder of such Senior Notes of the Third or Fourth Series such additional amount ("Additional Amount") as shall be necessary in order that the amount received by such Holder after withholding or deduction shall equal the amount that would otherwise have been due to such Holder in the absence of such withholding or deduction, except that no such Additional Amounts shall be payable: (A) to, or to a Person on behalf of, a Holder who is liable for such Gross-Up Taxes with respect to the Senior Notes of the Third or Fourth Series or the Guarantee, by reason of such Holder having some connection with the relevant Taxing Jurisdiction (including being a citizen or resident or national of, or carrying on a business or maintaining a permanent establishment in, or being physically present in, such Taxing Jurisdiction) other than the mere holding of a Senior Note of the Third or Fourth Series or the receipt of principal and interest (including payments of discount and premium, if any) in respect thereof or in respect of the Guarantee; (B) to, or to a Person on behalf of, a Holder who presents a Senior Note of the Third or Fourth Series (whenever presentation is required) for payment more than 30 days after the date on which payment first becomes due except to the extent that such Holder would have been entitled to such Additional Amounts on presenting such Senior Note of the Third or Fourth Series for payment on the last day of such period of 30 days; (C) to, or to a Person on behalf of, a Holder who presents a Senior Note of the Third or Fourth Series (when presentation is required) other than at a Place of Payment in The City of New York or, so long as the Senior Notes of the Third or Fourth Series are listed on the Luxembourg Stock Exchange, in Luxembourg; (D) to, or to a Person on behalf of, a Holder who would not be liable or subject to the withholding or deduction by making a declaration of non-residence or similar claim for exemption to the relevant tax authority; or (E) to, or to a Person on behalf of, a Holder of a Senior Note of the Third or Fourth Series that is issued in certificated form following and during the continuance of an Event of Default if such Holder (or any predecessor Holder) was one of the beneficial owners requesting that such certificated Senior Notes of the Third or Fourth Series be so issued. Such Additional Amounts will also not be payable where, had the beneficial owner of the Senior Note of the Third or Fourth Series (or any interest therein) been the Holder of the Senior Note of the Third or Fourth Series, it would not have been entitled to payment of Additional Amounts by reason of any one or more of clauses (A) through (E) above. If the Company or the Guarantor, as applicable, shall determine that Additional Amounts will not be payable because of the immediately preceding sentence, the Company or the Guarantor, as applicable, will inform such Holder promptly after making such determination setting forth the reason(s) therefor. 17. Special Redemption. If (a) the Company or the Guarantor ------------------ certifies to the Trustee prior to the giving of a notice as provided below that it has or will become obligated to pay Additional Amounts with respect to the Senior Notes of the Third or Fourth Series as a result of either (x) any change in, or amendment to, or clarification of, or announced change to occur in the future in, the laws or regulations of the Taxing Jurisdiction or any political subdivision or any authority or agency thereof or therein having power to tax or levy duties, or any change in the application or interpretation of such laws or regulations, which change or amendment becomes effective on or after the date of the offering memorandum or (y) the issuance of certificated registered Senior Notes of such Series pursuant to either (i) an Optional Certificated Security Request, as defined in the Deposit Agreement, (ii) the unwillingness or inability of DTC to continue to hold the Book-Entry Interests with respect to the global Senior Notes of such Series or interests therein or DTC's ceasing to be a "clearing agency" registered under the United States Securities Exchange Act of 1934, as amended, and, in either case, a successor is not appointed by the Company within 120 days, or (iii) the unwillingness or inability of the Book-Entry Depositary to continue to act as such and a successor is not appointed by the Company within 120 days, and (b) such obligation cannot be avoided by the Company or the Guarantor taking reasonable measures available to it, and, prior to the giving of a notice of redemption as hereinafter in this paragraph provided, the Company or the Guarantor delivers to the Trustee the certificate referred to in the last sentence of this paragraph, then the Company shall have the right, at its option, upon not less than 30 days nor more than 60 days' prior written notice of redemption to the Holders of Senior Notes of such Series, to redeem the Senior Notes of such Series, in whole but not in part, at the principal amount thereof plus accrued and unpaid interest thereon, and accrued Additional Amounts with respect thereto, if any, provided that no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Guarantor or the Company would be obligated to pay any such Additional Amounts with respect to such Series. Prior to the mailing of any notice of redemption pursuant to this paragraph, the Company shall deliver to the Trustee a certificate signed by an officer of the Company stating that the obligation referred to in (a) above cannot be avoided by the Guarantor or the Company taking reasonable measures available to it, and the Trustee shall accept, and shall be fully protected in relying upon, such certificate as sufficient evidence of the condition precedent set out in (b) above, in which event it shall be conclusive and binding on the Holders. 18.

In case of the failure of TXU Eastern Funding Company, a corporation incorporated under the laws of England and Wales (the "Company", which term includes any successor under the Indenture), punctually to make any such payment, the Guarantor hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Company. The Guarantor's obligation to make a guarantee payment may be satisfied by direct payment of the required amounts by the Guarantor to the Holder of such Security or to a Paying Agent, or by causing the Company to pay such amount to such Holder or a Paying Agent. Except as provided pursuant to Section 608 of the Indenture, this Guarantee is an unsecured and unsubordinated obligation of the Guarantor and shall at all times rank at least pari passu with each other Guarantee issued pursuant to the Indenture and, except as permitted by Sections 608 and 806 of the Indenture, will rank at least pari passu with all other unsecured unsubordinated indebtedness of the Guarantor. The Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or the Indenture, any failure to enforce the provisions of such Security or the Indenture, any extension of time for payment or performance by the Company as provided by such Security or the Indenture, or any waiver, modification or indulgence granted to the Company with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however, that notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or change any redemption provisions thereof (including any change to increase any premium payable upon redemption thereof) or change the Stated Maturity thereof. The Guarantor hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or the Holder of such Security exhaust any right or take any action against the Company or any other Person, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged in respect of such Security except by complete performance of the obligations contained in such Security and in this Indenture and in this Guarantee.

The Guarantor hereby agrees that, in the event of a default in payment of principal, or premium, if any, or interest, if any, on such Security, whether at its Stated Maturity, by declaration of acceleration, call for redemption, or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Security, subject to the terms and conditions set forth in the Indenture, directly against the Guarantor to enforce this Guarantee without first proceeding against the Company. The Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities, to collect interest on the Securities, or to enforce or exercise any other right or remedy with respect to the Securities, the Guarantor will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights been permitted to be exercised by the Trustee or any of the Holders. The obligations of the Guarantor hereunder with respect to such Security shall be continuing and irrevocable until the date upon which the entire principal of, premium, if any, and interest and Additional Amounts, if any, on such Security has been, or has been deemed pursuant to the provisions of Article Seven of the Indenture to have been, paid in full or otherwise discharged.

This Guarantee shall remain in full force and effect and continue notwithstanding any petition filed by or against the Company for liquidation or reorganization, the Company becoming insolvent or making an assignment for the benefit of creditors or a receiver or trustee being appointed for all or any significant part of the Company's assets, and shall, to the fullest extent permitted by law, continue to be effective or reinstated, as the case may be, if at any time payment of the Security upon which this Guarantee is endorsed, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by the Holder of such Security, whether as a "voidable preference," "fraudulent transfer," or otherwise, all as though such payment or performance had not been made.

THE BANK OF NEW YORK, as Trustee By: -------------------------- Authorized Signatory [FORM OF REVERSE OF SENIOR NOTE] This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture (For Unsecured Debt Securities), dated as of May 1, 1999 (herein, together with any amendments thereto, called the "Indenture", which term shall have the meaning assigned to it in such instrument), among the Company, TXU Eastern Holdings Limited, as Guarantor (herein called the "Guarantor," which term includes any successor under the Indenture) and The Bank of New York, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer's Certificate filed with the Trustee on May 13, 1999, creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Securities of this series will be redeemable as a whole at any time or in part, from time to time, at the option of the Company, at a Redemption Price equal to the sum of (a) the greater of (i) 100% of the principal amount of the Securities of this series to be redeemed, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Securities from the Redemption Date to the maturity date, computed by discounting such payments, in each case, to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, plus (b) accrued interest on the principal amount of such Securities to the Redemption Date plus (c) any accrued Additional Amounts. "Treasury Rate" means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of such Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining terms of such Securities of this series. "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company. "Business Day," when used for purposes of calculating the Redemption Price, shall mean a Business Day (as defined in the Indenture) in New York City, New York. "Comparable Treasury Price" means, with respect to any Redemption Date, (i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for US Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the average of the Reference Treasury Dealer Quotations actually obtained by the Trustee for such Redemption Date. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such Redemption Date. "Reference Treasury Dealer" means each of Lehman Brothers Inc. and Morgan Stanley & Co. Incorporated and their respective successors; provided, however, that if either of the foregoing shall cease to be a primary US Government securities dealer in New York City (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer. Notwithstanding Section 404 of the Indenture, the Trustee shall give the bearer of this Security notice of any redemption hereof in such manner as the Trustee deems necessary or desirable. So long as the Securities are listed on the Luxembourg Stock Exchange and the rules of the Luxembourg Stock Exchange so require, notices to Holders of the Securities will be published in a leading daily newspaper having general circulation in Luxembourg (which is expected to be the Luxemburger Wort). Upon payment of the Redemption Price, on and after the Redemption Date interest and any Additional Amounts will cease to accrue on the Securities of this series or portions thereof called for redemption. The Company shall deliver to the Trustee before any Redemption Date for the Securities of this series its calculation of the Redemption Price applicable to such redemption. Except with respect to the obligations of the Trustee expressly set forth in the foregoing definitions of "Comparable Treasury Issue" and "Comparable Treasury Price," the Trustee shall be under no duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon the Company's calculation of any Redemption Price of the Securities of this series. In lieu of stating the Redemption Price, notices of redemption of the Securities of this series shall state substantially the following: "The Redemption Price of the Notes of the Securities of this series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such Securities, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon from the Redemption Date to the maturity date, computed by discounting such payments, in each case, to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Indenture) plus 20 basis points plus accrued interest on the principal amount hereof to the Redemption Date plus accrued Additional Amounts, if any."

The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of authorized denominations, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The bearer of this Security shall be treated as the owner of it for all purposes, subject to the terms of the Indenture.

In case of the failure of TXU Eastern Funding Company, a corporation incorporated under the laws of England and Wales (the "Company", which term includes any successor under the Indenture), punctually to make any such payment, the Guarantor hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Company. The Guarantor's obligation to make a guarantee payment may be satisfied by direct payment of the required amounts by the Guarantor to the Holder of such Security or to a Paying Agent, or by causing the Company to pay such amount to such Holder or a Paying Agent. Except as provided pursuant to Section 608 of the Indenture, this Guarantee is an unsecured and unsubordinated obligation of the Guarantor and shall at all times rank at least pari passu with each other Guarantee issued pursuant to the Indenture and, except as permitted by Sections 608 and 806 of the Indenture, will rank at least pari passu with all other unsecured unsubordinated indebtedness of the Guarantor. The Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or the Indenture, any failure to enforce the provisions of such Security or the Indenture, any extension of time for payment by the Company as provided by such Security, or any waiver, modification or indulgence granted to the Company with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however, that notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or change any redemption provisions thereof (including any change to increase any premium payable upon redemption thereof) or change the Stated Maturity thereof.

TXU EASTERN FUNDING COMPANY By: ------------------------- [FORM OF GUARANTEE] TXU Eastern Holdings Limited, a corporation incorporated under the laws of England and Wales (the "Guarantor", which term includes any successor under the Indenture (the "Indenture") referred to in the Security upon which this Guarantee is endorsed), for value received, hereby unconditionally and irrevocably guarantees to the Holder of the Security upon which this Guarantee is endorsed, the due and punctual payment of the principal of, and premium, if any, and interest on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by declaration of acceleration, call for redemption, or otherwise, in accordance with the terms of such Security and of the Indenture, regardless of any defense, right of set-off or counterclaim that the Guarantor may have (except the defense of payment). In case of the failure of TXU Eastern Funding Company, a corporation incorporated under the laws of England and Wales (the "Company", which term includes any successor under the Indenture), punctually to make any such payment, the Guarantor hereby agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, and as if such payment were made by the Company. The Guarantor's obligation to make a guarantee payment may be satisfied by direct payment of the required amounts by the Guarantor to the Holder of such Security or to a Paying Agent, or by causing the Company to pay such amount to such Holder or a Paying Agent. Except as provided pursuant to Section 608 of the Indenture, this Guarantee is an unsecured and unsubordinated obligation of the Guarantor and shall at all times rank at least pari passu with each other Guarantee issued pursuant to the Indenture and, except as permitted by Sections 608 and 806 of the Indenture, will rank at least pari passu with all other unsecured unsubordinated indebtedness of the Guarantor. The Guarantor hereby agrees that its obligations hereunder shall be absolute and unconditional irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of such Security or the Indenture, any failure to enforce the provisions of such Security or the Indenture, any extension of time for payment by the Company as provided by such Security, or any waiver, modification or indulgence granted to the Company with respect thereto, by the Holder of such Security or the Trustee or any other circumstance which may otherwise constitute a legal or equitable discharge or defense of a surety or guarantor; provided, however, that notwithstanding the foregoing, no such waiver, modification or indulgence shall, without the consent of the Guarantor, increase the principal amount of such Security, or increase the interest rate thereon, or change any redemption provisions thereof (including any change to increase any premium payable upon redemption thereof) or change the Stated Maturity thereof. The Guarantor hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or the Holder of such Security exhaust any right or take any action against the Company or any other Person, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company, protest or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Guarantee will not be discharged in respect of such Security except by complete performance of the obligations contained in such Security and in this Indenture and in this Guarantee. This Guarantee shall constitute a guarantee of payment and not of collection. The Guarantor hereby agrees that, in the event of a default in payment of principal, or premium, if any, or interest, if any, on such Security, whether at its Stated Maturity, by declaration of acceleration, call for redemption, or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Security, subject to the terms and conditions set forth in the Indenture, directly against the Guarantor to enforce this Guarantee without first proceeding against the Company. The Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities, to collect interest on the Securities, or to enforce or exercise any other right or remedy with respect to the Securities, the Guarantor will pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights been permitted to be exercised by the Trustee or any of the Holders. The obligations of the Guarantor hereunder with respect to such Security shall be continuing and irrevocable until the date upon which the entire principal of, premium, if any, and interest and Additional Amounts, if any, on such Security has been, or has been deemed pursuant to the provisions of Article Seven of the Indenture to have been, paid in full or otherwise discharged. The Guarantor shall be subrogated to all rights of the Holder of each Security upon which its Guarantee is endorsed against the Company in respect of any amounts paid by the Guarantor on account of such Security pursuant to the provisions of its Guarantee or the Indenture; provided, however, that the Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of, and premium, if any, and interest, if any, and Additional Amounts, if any, on all Securities issued under the Indenture shall have been paid in full. This Guarantee shall remain in full force and effect and continue notwithstanding any petition filed by or against the Company for liquidation or reorganization, the Company becoming insolvent or making an assignment for the benefit of creditors or a receiver or trustee being appointed for all or any significant part of the Company's assets, and shall, to the fullest extent permitted by law, continue to be effective or reinstated, as the case may be, if at any time payment of the Security upon which this Guarantee is endorsed, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by the Holder of such Security, whether as a "voidable preference," "fraudulent transfer," or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned on such Security, such Security shall, to the fullest extent permitted by law, be reinstated and deemed paid only by such amount paid and not so rescinded, reduced, restored or returned. This Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication of the Security upon which this Guarantee is endorsed shall have been manually executed by or on behalf of the Trustee under the Indenture. All terms used in this Guarantee which are defined in the Indenture shall have the meanings assigned to them in such Indenture. This Guarantee shall be deemed to be a contract made under the laws of the State of New York, and for all purposes shall be governed by and construed in accordance with the laws of the State of New York. IN WITNESS WHEREOF, the Guarantor has caused this Guarantee to be executed as of the date first written above. TXU EASTERN HOLDINGS LIMITED By: ------------------------- [FORM OF CERTIFICATE OF AUTHENTICATION] CERTIFICATE OF AUTHENTICATION Dated: This is one of the Securities of the series designated therein and the Guarantee thereof referred to in the within- mentioned Indenture. THE BANK OF NEW YORK, as Trustee By: ----------------------------- Authorized Signatory [FORM OF REVERSE OF CERTIFICATED EXCHANGE NOTE] This Security is one of a duly authorized issue of securities of the Company (herein called the "Securities"), issued and to be issued in one or more series under an Indenture (for Unsecured Debt Securities), dated as of May 1, 1999 (herein, together with any amendments thereto, called the "Indenture", which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York, as Trustee (herein called the "Trustee", which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture, including the Board Resolutions and Officer's Certificate filed with the Trustee on May 13, 1999, creating the series designated on the face hereof, for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof. The Securities of this series will be redeemable as a whole at any time or in part, from time to time, at the option of the Company, at a Redemption Price equal to the sum of (a) the greater of (i) 100% of the principal amount of the Securities of this series to be redeemed, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on such Securities from the Redemption Date to the maturity date, computed by discounting such payments, in each case, to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points, plus (b) accrued interest on the principal amount of such Securities to the Redemption Date plus (c) any accrued Additional Amounts. "Treasury Rate" means, with respect to any Redemption Date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. "Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of such Securities of this series to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining terms of such Securities of this series. "Independent Investment Banker" means one of the Reference Treasury Dealers appointed by the Trustee after consultation with the Company. "Business Day," when used for purposes of calculating the Redemption Price, shall mean a Business Day (as defined in the Indenture) in New York City, New York. "Comparable Treasury Price" means, with respect to any Redemption Date, (i) the average of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) on the third Business Day preceding such Redemption Date, as set forth in the daily statistical release (or any successor release) published by the Federal Reserve Bank of New York and designated "Composite 3:30 p.m. Quotations for US Government Securities" or (ii) if such release (or any successor release) is not published or does not contain such prices on such Business Day, the average of the Reference Treasury Dealer Quotations actually obtained by the Trustee for such Redemption Date. "Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m. on the third Business Day preceding such Redemption Date. "Reference Treasury Dealer" means each of Lehman Brothers Inc. and Morgan Stanley & Co. Incorporated and their respective successors; provided, however, that if either of the foregoing shall cease to be a primary US Government securities dealer in New York City (a "Primary Treasury Dealer"), the Company shall substitute therefor another Primary Treasury Dealer. Notice of any redemption will be mailed at least 30 days but no more than 60 days before the Redemption Date to each Holder of the Securities of this series to be redeemed. Upon payment of the Redemption Price, on and after the Redemption Date interest and any Additional Amounts will cease to accrue on the Securities of this series or portions thereof called for redemption. The Company shall deliver to the Trustee before any Redemption Date for the Securities of this series its calculation of the Redemption Price applicable to such redemption. Except with respect to the obligations of the Trustee expressly set forth in the foregoing definitions of "Comparable Treasury Issue" and "Comparable Treasury Price," the Trustee shall be under no duty to inquire into, may presume the correctness of, and shall be fully protected in acting upon the Company's calculation of any Redemption Price of the Securities of this series. In lieu of stating the Redemption Price, notices of redemption of the Securities of this series shall state substantially the following: "The Redemption Price of the Securities of this series to be redeemed shall equal the sum of (a) the greater of (i) 100% of the principal amount of such Securities, and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon from the Redemption Date to the maturity date, computed by discounting such payments, in each case, to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Indenture) plus 20 basis points plus accrued interest on the principal amount hereof to the Redemption Date plus accrued Additional Amounts, if any." Except as provided herein, Article Four of the Indenture shall apply to redemptions of the Securities of this series. If the Company or the Guarantor is required to pay Additional Amounts with respect to Securities of this series, the Company has the right to redeem this Security as set forth in the Officer's Certificate described above. The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security upon compliance with certain conditions set forth in the Indenture, including the Officer's Certificate described above. If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of all series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of a majority in aggregate principal amount of the Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of Securities of all series at the time Outstanding in respect of which an Event of Default shall have occurred and be continuing a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein. No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed. The Securities of this series are issuable only in registered form without coupons in denominations of $10,000 and in integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and of authorized denominations, as requested by the Holder surrendering the same. No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the absolute owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture and in the Officer's Certificate establishing the terms of the Securities of this series.
