the cure period provided in the Assigned Agreement or (ii) delivery of such

other obligations, or any other Financing Liabilities, are outstanding under
the Financing Documents and until the same have been satisfied in full, all
payments to be made by the Consenting Party with respect to the Assigned
Agreement shall be in lawful money of the United States of America. The

hereby agrees to, make all such payments with respect to the Assigned

Senior Parties shall have cured, or shall be diligently pursuing a cure of,
or shall have entered into a binding obligation providing for the cure of,
any default susceptible of being corrected by Assignee or any of the Senior
Parties or by a purchaser at any judicial or non-judicial sale, the
Consenting Party shall, promptly, and in no event longer than ten (10) days
after receipt of written request therefor; provided, such request is received
by the Consenting Party not more than 60 days after any event specified in
clause (a) or (b) above, execute and deliver an agreement to the Assignee,
any of the Senior Parties or any of their respective nominees, purchasers,
assignees or transferees, as the case may be, for the remainder of

Assignee nor any of the Senior Parties has any obligation hereunder to extend
credit to the Consenting Party or any contractor of the Consenting Party at
any time for any purpose. Neither the Assignee nor any of the Senior Parties
shall have any obligation to the Consenting Party under the Assigned
Agreement unless and until such time as such entity elects to succeed to the
interest of the Company under the Assigned Agreement in accordance with this
Consent to Assignment. Upon the occurrence and during the continuance of an
event of default under any of the Security Documents, the Assignee or any of
the Senior Parties shall have the right to the extent authorized under the
Security Documents, to (a) take possession of the Project and operate the
same, (b) sell or otherwise transfer their interest in the Project and any
purchaser at such sale shall succeed to the Assignee's or the Senior Parties'
rights hereunder, as the case may be, and (c) exercise all rights of the
Company under the Assigned Agreement in accordance with the terms thereof. In
the case of subsection (b) above, the Assignee and the Senior Parties agree
that any purchaser, assignee, or transferee of the Project who assumes the
Assigned Agreement shall assume in writing the obligations of the Company
under the Assigned Agreement. Subject to the Assignee's compliance with the
provisions of the Assigned Agreement (if applicable) and the terms of this
Consent to Assignment, the Consenting Party shall cooperate with the Assignee
and comply in all respects in the Assignee's exercise of such rights. Without
limiting the generality of the foregoing, upon the occurrence and during the
continuance of an event of default under any of the Financing Documents, the
Assignee, any of the Senior Parties or any of their respective designees or
assignees satisfying the qualification set forth in this Section 8 shall have
the full right and power to enforce directly against the Consenting Party all
obligations of the Consenting Party under the Assigned Agreement and to
otherwise exercise all remedies thereunder, and to make all demands and give
all notices and make all requests required or permitted to be made by the
Company under the Assigned Agreement. The Assignee, any of the Senior Parties
or any of their respective assignees or designees satisfying the
qualification set forth in this Section 8 shall have the right, but not the
obligation, to perform any act, duty or obligation required of the Company
thereunder within the time periods provided in the Assigned Agreement;
provided that nothing herein shall require the Assignee, any of the Senior
Parties or any of their respective designees or assignees to cure any default
of the Company under the Assigned Agreement or to perform any act, duty or
obligation of the Company under the Assigned Agreement.

         10. REFINANCING. The Consenting Party hereby acknowledges that the
Company may from time to time obtain refinancing for the Project (including
privately or publicly placed bonds or notes), and the Consenting Party agrees
that it will promptly upon request execute in favor of the lenders providing
such refinancing a consent to assignment containing terms and conditions that
are mutually agreed between the parties.
