the NJBPU Approval or the FPSC Approval), then (i) the provisions of Section 2
hereof shall be null and void, (ii) the Borrower shall then owe a fee (the

(iv) the compensation, reimbursement and indemnification provisions contained in

<PAGE>

contained in the Credit Agreement or any other Loan Document, all of which are
ratified and affirmed in all respects and shall continue in full force and
effect. Nothing herein shall be deemed to entitle the Borrower to a consent to,
or a waiver, amendment, modification or other change of, any of the terms,
conditions, obligations, covenants or agreements contained in the Credit
Agreement in similar or different circumstances. This Agreement shall apply and
be effective only with respect to the provisions of the Credit Agreement
specifically referred to herein. Upon this Agreement becoming effective as

and are not to affect the construction of, or to be taken into consideration in
interpreting, this Agreement.

          (d) THIS AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY THE LAWS OF THE STATE OF NEW YORK. The parties hereto each hereby consent to
the non-exclusive jurisdiction of the state and federal courts of the State of
New York and irrevocably waive all right to trial by jury in any action,
proceeding or counterclaim arising out of or relating to this Agreement.

          (e) This Agreement may be executed in any number of counterparts, each
of which shall be an original but all of which, when taken together, shall
constitute but one instrument. Delivery of an executed counterpart of this
Agreement by fax will be deemed as effective as delivery of an originally
executed counterpart.

          IN WITNESS WHEREOF, the parties hereto have caused
