Subordination Upon an Event of Default. Upon the occurrence of a Default or an Event of Default, or any event that constitutes a "default" or an "event of default" under any Financing Document (other than in circumstances when the provisions of Section 4 of this Agreement are applicable), then, unless and until such Default, Event of Default or other event, as the case may be, shall have been remedied or waived or shall have ceased to exist, no direct or indirect payment (in cash, property or securities or by set-off or otherwise), including any payment to the holder of any Subordinated Claim by reason of the subordination of any indebtedness or other obligation to or any guarantee of such Subordinated Claim, shall be made or agreed to be made on account of any Subordinated Claim, or as a sinking fund for any Subordinated Claim, or in respect of any redemption, retirement, purchase or other acquisition of any Subordinated Claim. 6. Turnover of Improper Payments. If any payment or distribution of any character, whether in cash, securities or other property, or any security, shall be received by any holder of any Subordinated Claim in contravention of any of the terms hereof and before all Senior Claims have been indefeasibly paid in full in cash or cash equivalents and all Commitments have been terminated, such payment or distribution or security shall be received in trust for the benefit of, and shall forthwith be paid over or delivered and transferred to, the holders of Senior Claims at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Claims remaining unpaid, to the extent necessary to pay all such Senior Claims in full. In the event of the failure of any holder of any Subordinated Claim to endorse or assign any such payment, distribution or security, each holder of any Senior Claim is hereby irrevocably authorized to endorse or assign the same. 5 7. Limitation on Actions. (a) Each holder of a Subordinated Claim (or any instrument evidencing the same) by acceptance thereof agrees and undertakes that, without the prior written consent of the Collateral Agent (as directed by the Agent Bank, acting in accordance with the Credit Agreement), prior to the date on which all Senior Claims shall have been indefeasibly paid in full in cash or cash equivalents and all Commitments shall have been terminated: (i) such holder will not take, obtain or hold (or permit anyone acting on its behalf to take, obtain or hold) any assets of NRGG Funding or NRGMI, whether as a result of any administrative, legal or equitable action, or otherwise, in violation of this Agreement; (ii) such holder will not accelerate payment of such Subordinated Claim or otherwise require such Subordinated Claim to be paid prior to its stated or scheduled maturity date; (iii) such holder will not commence, prosecute or participate in (A) any administrative, legal or equitable action against NRGG Funding or NRGMI relating to any Subordinated Claim, including, without limitation, any Proceeding, (B) any other administrative, legal or equitable action relating to any Subordinated Claim or (C) any action to enforce or collect any judgment obtained in respect of, or to enforce or exercise remedies arising under or pursuant to any Lien or other security interest securing, any Subordinated Claim; and (iv) such holder shall not in any manner foreclose upon, take possession of or attempt to realize on any of the Shared Collateral. (b) If any holder of a Subordinated Claim, in violation of the provisions herein set forth, shall commence, prosecute or participate in any suit, action, case or Proceeding referred to in clause (a) above, NRGG Funding or NRGMI, as the case may be, may interpose as a defense or plea the provisions set forth herein, and any holder of any Senior Claim may intervene and interpose such defense or plea in its own name or in the name of NRGG Funding or NRGMI, as the case may be, and shall, in any event, be entitled to restrain the enforcement of the provisions of the Subordinated Claims in its own name or in the name of NRGG Funding or NRGMI, as the case may be, in the same suit, action, case or Proceeding or in any independent suit, action, case or Proceeding. 8. Disposition or Release of Collateral. If at any time or from time to time after the occurrence of an Event of Default, the Shared Collateral, or any portion thereof, is in any manner sold or otherwise transferred, each holder of a Subordinated Claim shall be deemed to have given irrevocable consent to such disposition if the Collateral Agent (as directed by the Agent Bank, acting in accordance with the Credit 6 Agreement) for any reason consents to such disposition, and in any event no holder of a Subordinated Claim shall be entitled to receive any proceeds (cash or non-cash) of such disposition unless and until all of the Senior Claims have been indefeasibly paid in full in cash or cash equivalents and all Commitments have been terminated. In the event of such disposition of all or any portion of the Shared Collateral, each holder of a Subordinated Claim shall, without further consideration, execute any and all instruments of release as the Collateral Agent shall require, failing which the Collateral Agent shall have the right to execute any such release on behalf of and as attorney-in-fact for such holder, which power of attorney shall be irrevocable. 9. Breach of Agreement. If NRG Energy or any other holder of a Subordinated Claim breaches any of the provisions of this Agreement, or if any payment is made on any Subordinated Claim that is not permitted by the provisions of this Agreement, the holders of Senior Claims shall have the right to declare any or all of such Senior Claims due and payable and pursue all of their rights and remedies under applicable state or federal Law. Nothing herein contained, however, is intended to compel NRG Energy or the Secured Parties at any time to declare NRGG Funding, NRGMI or the Borrower, as the case may be, to be in default under their respective agreements with NRGG Funding, NRGMI or the Borrower, as the case may be. All rights and remedies of NRG Energy and the Secured Parties, respectively, with respect to the Shared Collateral, the Borrower, NRGG Funding, or NRGMI and any other obligor concerning the Senior Claims or the Subordinated Claims, respectively, are cumulative and not alternative. 10. No Prejudice or Impairment. (a) The rights under these subordination provisions of the holders of any of the Senior Claims as against the holders of any of the Subordinated Claims shall remain in full force and effect without regard to, and shall not be impaired or affected by: (i) any act or failure to act on the part of the Borrower, NRGG Funding or NRGMI; (ii) any extension or indulgence in respect of any payment or prepayment of any Senior Claim or any part thereof or in respect of any other amount payable to any holder of any Senior Claim; (iii) any amendment, modification or waiver of, or addition or supplement to, or deletion from, or compromise, release, consent or other action in respect of, any of the terms of any Senior Claim, any Senior Agreement or any other agreement which may be made relating to any Senior Claim; (iv) any exercise or non-exercise by the holder of any Senior Claim of any right, power, privilege or remedy under or in respect of such Senior Claim, the Senior Agreements or this Agreement or any waiver of any such right, 7 power, privilege or remedy or of any default in respect of such Senior Claim, the Senior Agreements or this Agreement, or any receipt by the holder of any Senior Claim of any security, or any failure by such holder to perfect a security interest in, or any release by such holder of, any security for the payment of such Senior Claim; (v) any merger or consolidation of the Borrower, NRGG Funding or NRGMI or any of their respective subsidiaries into or with any other Person, or any sale, lease or transfer of any or all of the assets of the Borrower, NRGG Funding or NRGMI or any of their respective subsidiaries to any other Person; (vi) absence of any notice to, or knowledge by, any holder of any Subordinated Claim of the existence or occurrence of any of the matters or events set forth in the foregoing subdivisions (i) through (v); or (vii) any other circumstance. (b) Each holder of a Subordinated Claim unconditionally waives (i) notice of any of the matters referred to in clause (a) of this Section 10, (ii) all notices which may be required, whether by statute, rule of law or otherwise, to preserve intact any rights of any holder of any Senior Claim against the Borrower, NRGG Funding or NRGMI, including, without limitation, any demand, presentment and protest, proof of notice of nonpayment under any Senior Claim or the Senior Agreements, and notice of any failure on the part of the Borrower, NRGG Funding or NRGMI to perform and comply with any covenant, agreement, term or condition of the Senior Claims or the Senior Agreements, (iii) any right to the enforcement, assertion or exercise by any holder of any Senior Claim of any right, power, privilege or remedy conferred in such Senior Claim or the Senior Agreements, or otherwise, (iv) any requirement of diligence on the part of any holder of any Senior Claim, (v) any requirement on the part of any holder of any Senior Claim to mitigate damages resulting from any default under such Senior Claim or the Senior Agreements, and (vi) any notice of any sale, transfer or other disposition of any Senior Claim by any holder thereof. (c) The obligations of the holders of Subordinated Claims under this Agreement shall continue to be effective, or be reinstated, as the case may be, if at any time any payment in respect of any Senior Claim, or any other payment to any holder of any Senior Claim in its capacity as such, is rescinded or must otherwise be restored or returned by the holder of such Senior Claim upon the occurrence of any Proceeding, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar official for, the Borrower, NRGG Funding, NRGMI or any substantial part of their respective properties, or otherwise, all of though such payment had not been made. 8 11. Subrogation. No holder of any Subordinated Claim shall have any subrogation or other rights as the holder of a Senior Claim, and each holder of any Subordinated Claim hereby waives all such rights of subrogation and all rights of reimbursement or indemnity whatsoever and all rights of recourse to any security for any Senior Claim, until such time as all of the Senior Claims have been indefeasibly paid in full in cash or cash equivalents and all Commitments have been terminated. 12.
