to time, the "Collateral Agency Agreement") to set forth their mutual
understanding with respect to (a) the exercise of certain rights, remedies and
options by the respective parties thereto under the above described documents,

and effect. Until all obligations under the Financing Documents have been
performed and paid in full, all obligations of the Consenting Party under the
Assigned Agreement shall inure to the benefit of the Assignee for the benefit of

to the Assigned Agreement instead of the Company.

Agreement, (d) none of the Company's rights under the Assigned Agreement has
been waived, (e) the assignment by the Company of the Assigned Agreement to the

Assigned Agreement or an event or condition which would, with the giving of
notice or lapse of time or both, constitute a default under the Assigned
Agreement, and (f) a foreclosure or other exercise of remedies under any of the
Security Documents or any sale thereunder by the Assignee, any of the Senior
Parties or any of their respective designees or assignees, whether by judicial
proceedings or under any power of sale contained therein, or any conveyance from

performance of its obligations under the Assigned Agreement, nor shall the
Consenting Party exercise any right it may have under the Assigned Agreement, at
law or in equity, to cancel, suspend or terminate the Assigned Agreement, or any
of its obligations thereunder, as the result of any default or other action or
omission (each, herein, a "default") of the Company unless the Consenting Party,
following expiry of all periods given the Company to cure such default, action
or omission, shall have given a copy of a notice of default to the Assignee,
such notice to be coupled with an opportunity to cure any such default within a
reasonable period, but in no event less than ninety (90) days from notice to the
Assignee (or, with respect to nonmonetary defaults or defaults the curing of
which requires the Assignee's possession of the Facility through foreclosure,
such longer period of time as may be necessary under the circumstances to
complete such foreclosure or cure such default, provided the Assignee, any of
the Senior Parties, or any of their respective designees or assignees is
diligently pursuing such cure or foreclosure), such cure period to commence upon
delivery of such notice to the Assignee, or, with respect to any defaults which
are not susceptible of being so corrected, to rectify to the Consenting Party's
reasonable satisfaction the effect upon the Consenting Party of such default by
the Company within such period provided, however, that if any such party is
prohibited from curing any such default by any process, stay or injunction
issued by any governmental authority or pursuant to any bankruptcy or insolvency
proceeding, then the time periods specified in this Section 4 for curing a

telecopy is then followed by a copy of such notice delivered by a method
specified in clause (a), (b) or (c) above.

Parties without such notice and the lapse of the

                                       3

notwithstanding, the Consenting Party shall continue performance under the
Assigned Agreement and resolve any dispute without discontinuing such
performance until the lapse of the notice and applicable cure periods or
extension periods. The Assignee, any of the Senior Parties or any of their
respective designees or assignees may, but shall be under no obligation to, make

the Company, with the same effect as if made or performed by the Company. If the
Assignee, any of the Senior Parties or any of their respective designees or
assignees fails to cure or rectify the effect of a default under the Assigned
Agreement or within ninety (90) days from notice to the Assignee (or, with
respect to nonmonetary defaults or defaults the curing of which requires the
curing party's possession of the Facility through foreclosure, such longer
period of time as may be necessary under the circumstances to complete such
foreclosure or cure such default, provided the Assignee, any of the Senior
Parties or any of their respective designees or assignees is diligently pursuing
such cure or such foreclosure), whichever is longer, such cure period to
commence upon such notice to the Assignee, the Consenting Party shall have all
its rights and remedies with respect to such default as set forth in the
Assigned Agreement.

         5. No Previous Assignment.

         The Consenting Party represents and warrants to the Assignee that it
has not assigned, transferred or hypothecated, nor previously consented to any
assignment, transfer or hypothecation of, the Assigned Agreement or any interest
therein.

         6. No Amendments Without Consent.

         The Consenting Party shall not amend, modify or consent to the
amendment or modification of the Assigned Agreement without the prior written
consent of the Assignee, unless the Company has certified to the Consenting
Party in writing that such amendment, modification or consent to amendment or
modification is permitted under the terms of the Financing Documents.

         7. Payments to Revenue Account.

         The Consenting Party hereby agrees that, so long as any notes, bonds,
loans, letters of credit, commitments or 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

credit to Account No. 630000041.2 (Revenue Account) Attention: Capital Markets
Trust Services, or to such other person and/or at such other address as the
Assignee may from time to time specify in writing to the Consenting Party. All
payments required to be made by the Consenting Party under the Assigned
Agreement shall be made without any offset, recoupment, abatement, withholding,
reduction or defense whatsoever, except as specifically permitted under the
Assigned Agreement.

         8. Protection of Assignee.

         In the event that either (a) the Company's interest in the Project
shall be sold, assigned or otherwise transferred pursuant to the exercise of any
right, power or remedy by the Assignee or pursuant to judicial proceedings, or
(b) the Company rejects all or a portion of the Assigned Agreement under Title
11, United States Code, or other similar Federal or state statute and such
rejection is approved by the appropriate bankruptcy court or is otherwise
effective pursuant to such statute, the Consenting Party shall, promptly, and in
no event longer than ten (10) days after receipt of written request therefor,
execute and deliver an agreement to the Assignee, any Senior Parties or any of
their respective nominees, purchasers, assignees or transferees, as the case may
be, for the remainder of the term of the Assigned Agreement and with the same
terms as are contained therein.. References in this Consent to Assignment to
"Assigned Agreement" shall be deemed also to include such new agreement.

         9. Acknowledgement of Assignee's Obligations and Rights.

         Neither the 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. The Assignee shall have no
obligation to the Consenting Party under the Assigned Agreement until such time
as the Assignee notifies the Consenting Party in writing of the Assignee's
election to exercise its rights hereunder. 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 which may include the Assignee or its
designees or assignees, shall have the right to succeed to the Assignee's or the
Senior Parties' rights hereunder ("Substitute Owner"), as the case may be, and
(c) exercise all rights of the Company under the Assigned Agreement in
accordance with the terms thereof. Subject to 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 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 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 otherwise
to 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 designees or assignees shall have the right, but not the
obligation, to perform any act, duty or obligation required of the Company
thereunder at any time; 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 except
during any such period that it shall have been a Substitute Owner and assumed
such duties and obligations. The obligations of any Substitute Owner shall be no
more than that of the Company under such Assigned Agreement, any Substitute
Owner shall have no personal liability to the Consenting Party for the
performance of such obligations and the sole recourse of the Consenting Party,
if there is a Substitute Owner, shall be to Substitute Owner's

                                       5


interest in the Facility. The Collateral Agent is not required to take any
discretionary action under this Agreement unless it receives written direction
from the Required Senior Parties. The Collateral Agent is entitled to receive
indemnification to its satisfaction before taking any action as directed by the
Required Senior Parties.

         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 no less favorable
to the Consenting Party than those terms and conditions contained in this
Consent to Assignment.
