obligations thereunder, as the result of any default or other action or omission
(each, herein, a "default") of the Company unless the Consenting Party,

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

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
following expiry of all periods given the Company to cure such default and 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

other address as the Assignee may have specified by written notice delivered in
accordance herewith, or (d) when transmitted by telecopy to the number specified

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

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 any payment or perform any act required thereunder
to be made or performed by 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 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, following
expiry of all periods given the Company to cure such default,, 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

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

other obligations, or any other Financing Liabilities, are outstanding under the
Financing Documents and until the same have been satisfied in full, all payments

Attention: Corporate Trust Administration, 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

         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


                                       4

<PAGE>


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 ("Substitute Owner") 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, 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

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 become 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 interest in the Facility.

         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.
