        (a)  the
Subordinated Claims shall be subordinate, to the extent and in the manner hereinafter set forth, to the prior payment of, and junior in right of payment to, any and
all Senior Leveraged Lease Obligations whether now existing or hereafter incurred or created (collectively, the "Senior Claims"); 

        (b)  Homer

and subject to Section 6.9 of the Participation Agreement and the applicable provisions of the Amended Security Deposit Agreement, Homer City may make payments of Subordinated Claims consisting
of Basic Lease Rent, Supplemental Rent and Renewal Lease Rent; and 

3

 

        (c)  without
the consent of the Lease Indenture Trustee, the Subordinated Parties shall not demand, sue for or accept (other than with respect to withdrawals from the Equity

Reserve Account pursuant to Section 4.4 of the Amended Security Deposit Agreement) from Homer City any payment or collateral in respect of any Subordinated Claims, or take any other action to

        (d)  Neither
Homer City nor the Subordinated Parties shall otherwise take any action prejudicial to or inconsistent with the priority position of the Secured Parties over the
Subordinated Parties created by this Section 2.1. 

        Section 2.2    Reliance.    All Senior Claims shall conclusively be deemed to have been created, contracted or
incurred in reliance on the subordination provisions contained in this Agreement and all dealings between Homer City, the Subordinated Parties and each of the holders of Senior Claims shall be deemed
to have been consummated in reliance upon the subordination provisions contained herein. 

        Section 2.3    Other Holders.    The subordination provisions set forth in this Agreement shall be binding upon
transferees or assignees of each of the Subordinated Parties and upon each other holder of

ARTICLE III
  WRONGFUL COLLECTIONS    
  

        Section 3.1    Turnover.    Should any payment on account of, or any collateral for any part of, any
Subordinated Claims be received by the Subordinated Party in violation of this Agreement or the provisions of Section 6.9 of the Participation
Agreement, such payment or collateral shall be delivered forthwith to the Security Agent in the same form as so received (with any necessary endorsement). Until so delivered, any such payment or
collateral shall be held by such Subordinated Party in trust for the holders of the Senior Claims and shall not be commingled with other funds or property of such Subordinated Party. The Security
Agent is hereby irrevocably authorized to supply any endorsement or assignment which may have been omitted which the Security Agent may reasonably deem necessary or advisable to enforce its rights
under this Agreement, including, without limitation, authority to receive, endorse and collect all instruments made payable to any Subordinated Party representing any distribution, interest payment or
other payments in respect of the Subordinated Claims. 

        Section 3.2    Survival of Obligation.    The obligation of the Subordinated Party to deliver to the Security
Agent any payment or collateral received in connection with any Subordinated Claims, as set forth in Section 3.1, shall survive and shall not be
in any way affected by the result of any (a) insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment, composition or other similar proceeding relating to Homer City, its
property or its creditors as such, (b) proceeding for any liquidation, dissolution or other winding-up of Homer City, voluntary or involuntary, whether or not involving insolvency
or bankruptcy proceedings, (c) assignment for the benefit of creditors, (d) other marshalling of the assets of Homer City or (e) general meeting of creditors of Homer City, in
each case, under the laws of the United States or any other jurisdiction (any such event, a "Proceeding"). 

 
 

ARTICLE IV
  PROCEEDINGS    
  

        Section 4.1    Commencement of Proceedings.    Except to the extent otherwise provided herein, no Subordinated
Party shall commence, or join with any other creditor or creditors of Homer City in commencing, any Proceeding against Homer City without the consent of the Lease Indenture Trustee. 

4

 

        Section 4.2    Payments and Distributions.    In the event of any Proceeding, until all Senior Leveraged Lease
Obligations shall have been paid in full, any payment or distribution of any kind or character on account of a Subordinated Claim, whether in cash, property or securities, which, but for the
subordination provisions of this Agreement would otherwise be payable or deliverable upon or in respect of Subordinated Claims, shall instead be paid over or delivered to the Security Agent and no
holder of Subordinated Claims shall be entitled to receive any such payment or distribution or any benefit therefrom. 

        Section 4.3    Enforcement of Subordinated Claims.    

        (a)    Cooperation.    The Subordinated Parties shall cooperate fully with the Security Agent and perform all acts
reasonably requested by the Security Agent to enable the Security Agent to enforce any Subordinated Claims, including, without limitation, filing appropriate proofs of claim and executing and

        (b)    Enforcement by the Subordinated Party.    After the commencement of any Proceeding, the requesting Subordinated
Party may (but shall not be required to) proceed to file a proof of claim, enter appearances and file affirmative or responsive pleadings with respect to such Subordinated Claims and take such
further steps with respect thereto, not inconsistent with this Agreement, as the requesting Subordinated Party may deem proper. 

        (c)    Subrogation.    The Subordinated Parties shall not have any subrogation or other rights as a holder of Senior
Claims, and each Subordinated Party hereby irrevocably 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 Claims, until such time as all Senior Leveraged Lease Obligations shall have been paid in full. Subject to and from and after the payment in full of all Senior Leveraged Lease Obligations, each
Subordinated Party shall be subrogated to any rights of the holders of Senior Claims to receive payments or distributions of cash, property or securities of Homer City applicable to any Subordinated
Claims until all amounts owing on such Subordinated Claims shall be paid in full. 

        (a)    Enforcement by the holders of the Senior Claims.    At any Proceeding, until all Obligations shall have been
paid in full, the holders of the Senior Claims are hereby irrevocably authorized (but not required) to: 

          (i)  enforce
claims comprising Subordinated Claims in the name of the Subordinated Party by proof of debt, proof of claim, suit or otherwise; 

        (ii)  collect
any assets of any Owner Lessor distributed, divided or applied by way of dividend or payment, and any securities issued, in each case, on account of
Subordinated Claims and apply the same, or the proceeds of any realization upon the same that the Indenture Estate in their discretion elect to effect, to Senior Claims until all Obligations shall
have been paid in full; provided, however, that the Lease Indenture Estate shall render any surplus to the Subordinated Party or its affiliates, as their interests appear, or interplead such surplus
with a court of competent jurisdiction; 

        (iii)  vote
claims comprising Subordinated Claims to accept or reject any plan of partial or complete liquidation, reorganization, arrangement, composition or extension; and 

        (iv)  take
generally any action in connection with any such Proceeding which the Subordinated Party might otherwise take.

forth, shall commence, prosecute or participate in any suit, action, case or Proceeding referred to in Section 5.1, the Owner Lessor may interpose as a defense or plea the provisions set forth
herein, and any holder of any Senior Claims may intervene and interpose such defense or plea in its own name or in the name of the Owner Lessor, and shall, in any event, be entitled to restrain the
enforcement of the provisions of any Subordinated Claims in its own name or in the name of the Owner Lessor, as the case may be, in the same suit, action, case or Proceeding or in any independent
