(b) Notwithstanding anything to the contrary contained in this Guaranty (but subject to the terms and provisions of Section 2.04(a) above), the total amount guaranteed by the Limited Guarantor hereunder shall be (i) limited to an amount calculated as described in Schedule 2.04 hereto, and (ii) subordinated to the extent described in Schedule 2.04(a) and Schedule 2.04(b) hereto; provided, however, that the foregoing shall cease to apply to the Limited Guarantor on the date on which the contractual obligation (or replacement thereof to the extent permitted by the terms of the Secured Debt Documents) that prohibited the Limited Guarantor from guaranteeing the Guaranteed Obligations in full or prohibited it from guaranteeing the Guaranteed Obligations on a non-subordinated basis, as applicable, shall no longer be in effect. Section 2.05 Stay of Acceleration. If acceleration of the time for payment of any amount payable by RRI or another Grantor under any Secured Debt Document is stayed upon the insolvency, bankruptcy or reorganization of RRI or such other Grantor, all such amounts otherwise subject to acceleration under the terms of such Secured Debt Document shall nonetheless be payable by the Limited Guarantor (unless it is the Grantor whose payment is so stayed) under this Guaranty forthwith on demand by the Collateral Trustee pursuant to an Act of Secured Debtholders. Section 2.06 Distribution of Payments. Any amounts received by the Collateral Trustee hereunder shall be deposited in the Collateral Account and shall, to the extent available for distribution, be distributed by the Collateral Trustee in accordance with the provisions of Article V of the Collateral Trust Agreement.

As required by the Indenture dated April 27, 2000 pursuant to which the Limited Guarantor issued its 12% Senior Notes due 2010 ("Indenture"), the amount guaranteed hereunder by the Limited Guarantor must meet each of the conditions listed below. 1) The fixed charge ratio of 2:1 (calculated in accordance with Section 4.09 of the Indenture) is satisfied for the Limited Guarantor's most recently ended four full fiscal quarters, treating the amount guaranteed by the Orion Bank Guarantors under the Credit Agreement and by the Limited Guarantor under the Guaranty as indebtedness and giving effect to such Guaranty as if it had been incurred at the beginning of such four quarter period, which amount is calculated as of March 28, 2003, to be $1,154,594,000 as of December 31, 2002, and 2) Either: a. the guaranteed amount hereunder, collectively with the amount guaranteed by the Orion Bank Guarantors, does not exceed 5% of the Limited Guarantor's consolidated tangible assets (collectively with the Limited Guarantor's investments in Liberty Electric Power, LLC., and any other investments relying upon the "permitted investment" exemption under the Indenture), which consolidated tangible assets are calculated as of March 28, 2003, to be $3,942,483,000 as of December 31, 2002 (5% of which is $197,124,000); or b. (i) at the time the Limited Guarantor entered into the Guaranty, and after giving pro forma effect thereto and to the guaranties of the Orion Bank Guarantors, the Limited Guarantor would have been permitted to incur at least $1.00 of additional indebtedness (treating the Guaranty and the guaranties of the Orion Bank Guarantors as indebtedness) pursuant to the fixed charge ratio described above; and (ii) the Guaranty, collectively with the guaranties of the Orion Bank Guarantors, satisfies the restricted payment ceiling test in Section 4.07 of the Indenture for the payment of dividends (such restricted payment ceiling being, generally, the sum of 50% of the aggregate consolidated net income for the Limited Guarantor plus 100% of any contributions to common equity from the sale of common stock), which restricted payment ceiling is calculated as of March 28, 2003, to be $1,100,450,000 as of December 31, 2002. Furthermore, because the Orion Bank Guarantors are separately guaranteeing the Guaranteed Obligations, the amount guaranteed hereunder shall be reduced by any amounts paid by the Orion Bank Guarantors pursuant to their guaranties of the Guaranteed Obligations. -9- SCHEDULE 2.04(a) SUBORDINATION PROVISIONS RELATING TO ORION POWER HOLDINGS, INC.

In the event any one or more of the provisions contained in this Schedule 2.04(a) should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). 5.06. No Amendments. Neither this Schedule 2.04(a) nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by each of OPH, the Collateral Trustee and the Lead Arrangers. 5.07. No Impairment of Sponsor Indebtedness. Notwithstanding anything to the contrary that may be set forth in the Guaranty or this Schedule 2.04(a), nothing in the Guaranty or this Schedule 2.04(a) is intended to, or shall, in any way limit or restrict the Lenders (as that term is defined in the Senior Credit Agreements) in exercising their rights and remedies under the Senior Credit Agreements and under the other Financing Documents (as that term is defined in the Senior Credit Agreements). -15- SCHEDULE 2.04(b) SUBORDINATION PROVISIONS RELATING TO ORION POWER HOLDINGS, INC. AND OPH INDENTURE Reference is made to the AMENDED AND RESTATED GUARANTY AGREEMENT (as the same may be amended, supplemented, or otherwise modified from time to time, the "Guaranty") dated as of July 1, 2003, made by Orion Power Holdings, Inc., a Delaware corporation ("OPH"), in favor of the Secured Parties, as defined in the Collateral Trust Agreement dated as of even date therewith (as the same may be amended, supplemented, or otherwise modified from time to time, the "Collateral Trust Agreement"), among Reliant Resources, Inc. ("RRI"), the subsidiaries of RRI parties thereto, including OPH, and Wachovia Bank, National Association, in its capacity as collateral trustee (together with its successors in such capacity the "Collateral Trustee") for the Secured Parties. Reference is also made to Schedule 2.04(a) to the Guaranty (as the same may be amended, amended and restated, modified, or replaced from time to time, "Schedule 2.04(a)"). The amounts guaranteed by OPH under the Guaranty have been subordinated to the "Obligations" (as such term is defined in Schedule 2.04(a), such Obligations, as defined therein, the "Project Obligations") to the extent set forth in Schedule 2.04(a). The Project Obligations are secured by a lien on assets of OPH pursuant to the OPH Pledge Agreement (as defined below), and consequently, for so long as the Project Obligations are secured by such assets of OPH, or any other property of OPH, the Project Obligations constitute "Indebtedness" (as defined in the Indenture defined below) of OPH. Section 4.09 of the Indenture provides that OPH shall not incur Indebtedness that is contractually subordinated to other Indebtedness of OPH unless such Indebtedness is also contractually subordinated in right of payment to the Notes pursuant to terms no less favorable to the Holders of the Notes (as such terms are defined below). OPH, having entered into the Guaranty and having subordinated the Indebtedness thereunder to the Project Obligations is, as contemplated by Section 4.09 of the Indenture, providing this subordination for the benefit of the Holders of the Notes. The Subordinated Creditors (as defined below), by their acceptance of the benefits of the Guaranty, and the Trustee and the Holders (as defined below), by their acceptance of the benefits of this Schedule 2.04(b), each agrees to be bound hereby. SECTION 1. Definitions. 1.01. Definition of Certain Terms Used Herein. As used herein, the following terms shall have the following meanings: "Holder" has the meaning assigned to such term in the Indenture. "Indebtedness" has the meaning assigned to such term in the Indenture as in effect on the date hereof. -16- "Indenture" means the Indenture dated as of April 27, 2000, between OPH and the Trustee, together with any amendments or supplements thereto that do not increase the principal outstanding amount of the Obligations under the Notes or such Indenture. "Obligations" has the meaning assigned to such term in the Indenture. "Notes" means the 12% Senior Notes due 2010 issued by OPH pursuant to the Indenture. "OPH Pledge Agreement" has the meaning assigned to such term in Schedule 2.04(a). "Senior Bank Indebtedness" means the "Senior Indebtedness" as that term is defined in Schedule 2.04(a). "Senior Indebtedness" means all present and future Obligations of OPH to the Holders under the Notes outstanding on the date hereof and under any replacement Notes issued pursuant to Section 2.07 of the Indenture. "Subordinated Creditors" means each of the Secured Parties, and their successors and assigns. "Subordinated Indebtedness" means all present and future obligations, liabilities and indebtedness of OPH to the Subordinated Creditors pursuant to the Guaranty. "Trustee" means Wilmington Trust Company, as indenture trustee for the Holders, and its successors or assigns as such indenture trustee. SECTION 2. Subordination. OPH and each Subordinated Creditor agrees as follows: 2.01. Agreement to Subordinate. OPH and each Subordinated Creditor agrees that so long as the Senior Bank Indebtedness constitutes "Indebtedness of the Company" within the meaning of Section 4.09 of the Indenture (as in effect on the date hereof), the Subordinated Indebtedness is subordinated in right of payment, to the extent and in the manner provided in this Section 2, to the Senior Indebtedness, and that such subordination is for the benefit of and enforceable by the Trustee for the benefit of the Holders. 2.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution of the assets of OPH to creditors upon a total or partial liquidation or a total or partial dissolution of OPH or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to OPH or its properties: (1) the Holders shall be entitled to receive payment in full of all Senior Indebtedness before the Subordinated Creditors shall be entitled to receive any payment of principal of or interest on or other amounts with respect to the Subordinated Indebtedness; and (2) until all Senior Indebtedness is paid in full, any distribution to which the Subordinated Creditors would be entitled but for this Section 2 shall be made to the Trustee for the benefit of the Holders as their interests may appear. 2.03. Default on Senior Indebtedness. If a default in payment of any Senior Indebtedness occurs, and the Collateral Trustee has received written notice from the Trustee of (i) the occurrence and existence of such payment default and (ii) the dollar amount of Senior -17- Indebtedness outstanding at such time, OPH may not pay any amounts with respect to the Subordinated Indebtedness unless theretofore or concurrently therewith, the Trustee, for the benefit of the Holders, shall have received payment in full, from OPH or from another Person for OPH's account, of a dollar amount of Senior Indebtedness equal to the dollar amount of Senior Indebtedness outstanding at such time. 2.04. When Distributions Must Be Paid Over. In the event that the Collateral Trustee or any Subordinated Creditor receives any payment of any Subordinated Indebtedness at a time when such payment is required by this Section 2 to be paid first to the Trustee for the benefit of the Holders, such payment shall be held by the Collateral Trustee or such Subordinated Creditor, in trust for the benefit of, and shall be paid forthwith over and delivered, upon proper written request, to the Trustee, for the benefit of the Holders, as their respective interests may appear, for application to the payment of all Senior Indebtedness remaining unpaid and required by this Section 2 to be paid before payment of Subordinated Indebtedness, to the extent necessary to pay such amount of Senior Indebtedness in full in accordance with its terms after giving effect to any concurrent payment or distribution to or for the Holders. 2.05. Subrogation. After all Senior Indebtedness that is required by this Section 2 to be paid before Subordinated Indebtedness may be paid is paid in full and until the Subordinated Indebtedness is paid in full, the Subordinated Creditors shall be subrogated to the rights of the Holders to receive distributions applicable to Senior Indebtedness to the extent that distributions otherwise payable to the Subordinated Creditors have been applied to payment of Senior Indebtedness. A distribution made under this Section 2 to the Trustee, for the benefit of the Holders, which otherwise would have been made to the Subordinated Creditors is not, as between OPH and the Subordinated Creditors, a payment by OPH on Senior Indebtedness. 2.06. Collateral Trustee Not Fiduciary for Holders. The Collateral Trustee shall not be deemed to owe any fiduciary duty to the Trustee or the Holders and shall not be liable to the Trustee or any Holder if it shall mistakenly pay over or distribute to the Subordinated Creditors, OPH, or any other Person, money or assets to which the Trustee or any Holder shall be entitled by virtue of this Section 2 or otherwise, except if such payment was made as a result of the willful misconduct or gross negligence of the Collateral Trustee. SECTION 3. Further Assurances. The Collateral Trustee and the Trustee, at any time and from tune to time upon the written request of the other, will promptly execute and deliver such further instruments and documents and take such further actions as the other may reasonably request for the purposes of obtaining or preserving the full benefits of this Schedule 2.04(b) and of the rights, priorities and powers herein granted. SECTION 4. Relative Rights. This Schedule 2.04(b) defines the relative rights of the Subordinated Creditors and the Holders, who are express third-party beneficiaries hereof. Nothing in this Schedule 2.04(b) shall: (1) impair, as between OPH and the Subordinated Creditors, the obligation of OPH, which is absolute and unconditional, to pay amounts owing in respect of the Subordinated Indebtedness in accordance with its terms; or (2) prevent the Collateral Trustee or any Subordinated Creditor (or any agent or trustee thereof) from exercising its available remedies upon an actionable default, subject to the rights of the Trustee, for the benefit of the Holders, to receive distributions otherwise payable to the Subordinated Creditors. No other Person shall have any right, benefit or other interest under this Schedule 2.04(b). -18- SECTION 5. Miscellaneous. 5.01. Notices.
