VI shall be applied by the Bank in accordance with Section 609 of the Indenture.

     SECTION 6.06.  REMEDIES CUMULATIVE. No remedy herein conferred upon or
reserved to the Bank is intended to be exclusive of any other available remedy,
but each and every such remedy shall be cumulative and in addition to every
other remedy given under this Mortgage or under any other Financing Document or
now or hereafter existing at law or in equity. No delay or omission to exercise
any right or power accruing upon any Event of Default shall impair any such
right or power, or shall be construed to be a waiver thereof or an acquiescence
therein, and every right or remedy given by this Mortgage to the Bank may be
exercised from time to time and as often as may be deemed expedient. In order to
entitle the Bank to exercise any remedy reserved to it in this Article VI, it
shall not be necessary to give any notice, other than such notice as may be
expressly required in this Mortgage.

     SECTION 6.07.  TERMINATION OF PROCEEDINGS. In case any proceeding taken by
the Bank on account of any Event of Default shall have been discontinued or
abandoned for any reason or shall have been determined adversely to the Bank,
then the Issuer, the Bank and the Company shall be restored to their former
positions and rights hereunder, and all rights, remedies and powers of the Bank
shall continue as if no such proceeding had been taken.

     SECTION 6.08.  WAIVER AND NON-WAIVER OF EVENT OF DEFAULT. (A) The Bank may,
in its discretion, in writing, agree to waive any Event of Default hereunder and
its consequences and annul any acceleration in accordance with Section 6.02
hereof. No such waiver shall extend to or affect any other existing or any
subsequent Event of Default.

          (B)  The failure of the Bank to insist upon strict performance of any
term hereof shall not be deemed to be a waiver of any term of this Mortgage.
Neither the Issuer nor the Company shall be relieved of its respective
obligations hereunder by reason of (1) failure of the Bank to comply with any
request of the Company to take any action to foreclose this Mortgage or
otherwise enforce any of the provisions hereof, (2) the release, regardless of
consideration, of the whole or any part of the Mortgaged Property, or (3) any
agreement or stipulation by the Bank extending the time of payment or otherwise
modifying or supplementing the terms of this Mortgage or any of the other
Financing Documents. The Bank may resort for the payment of the Mortgage
Indebtedness to any other security held by the Bank pursuant to the Financing
Documents in such order and manner as the Bank, in its discretion, may elect.
The Bank may take action to recover the Mortgage Indebtedness, or any portion
thereof, or to enforce any covenant hereof without prejudice to the right of the
Bank thereafter to foreclose this Mortgage. The rights of the Bank under this
Mortgage shall be separate, distinct and cumulative and none shall be given
effect to the exclusion of the others. No act of the Bank shall be construed as
an election to proceed under any one provision herein to the exclusion of any
other provision. No

                                       44

<PAGE>

waiver of any right of the Bank shall be effective unless it is in a writing
signed by an officer of the Bank.

     SECTION 6.09.  REPAYMENT AND SECURING OF EXPENSES PAID BY THE BANK. In the
event the Bank shall pay any premiums on any policies of insurance required to
be maintained or procured by Section 4.02 hereof, or in the event the Bank shall
expend any funds for the payment of any unpaid taxes or assessments upon the
Mortgaged Property, or pay or perform any other obligation of either the Issuer
or the Company under any of the Financing Documents, then in any such event such
payment shall be deemed to be secured by this Mortgage and shall be payable to
the Bank in the manner provided and with interest as provided herein, or if not
so provided herein, shall be payable on demand with interest at the Default
Interest Rate.

     SECTION 6.10.  REPAYMENT AND SECURING OF COLLECTION COSTS INCURRED BY THE
BANK. (A) In the event this Mortgage or the Bonds or any of the other Financing
Documents or all of the foregoing are placed in the hands of an attorney (1) for
collection of any sum payable hereunder or thereunder, (2) for the foreclosure
of this Mortgage, or (3) for the enforcement of any of the terms, conditions and
obligations of this Mortgage or any of the Financing Documents, the Company
agrees to pay all costs of collection (including reasonable counsel fees and
expenses) incurred by the Bank, together with interest thereon at the Default
Interest Rate. All such costs as incurred shall be deemed to be secured by this
Mortgage and collectible out of the proceeds of this Mortgage in any manner
permitted by law or by this Mortgage.

     (B)  In addition to and not in limitation of the foregoing, in any action
or proceeding to foreclose this Mortgage, or to recover or collect the debt
secured hereby, the provisions of law respecting the recovery of costs,
disbursements and allowances shall also apply. The reasonable expenses of
pursuing, searching for, retaking, receiving, holding, storing, safe-guarding,
any environmental testing and cleanup, insuring, accounting for, advertising,
preparing for sale or lease, selling, leasing and the like, plus attorney's
fees, fees for certified public accountants, fees for auctioneers, fees for
brokers and/or appraisers, fees for security guards, fees for environmental
auditors and engineers, fees for hazard insurance premiums, or any other
reasonable costs or disbursements whatsoever incurred by or contracted for by
the Bank in connection with the disposition of the Mortgaged Property (including
any of the foregoing incurred or contracted for by the Bank in connection with
any bankruptcy or insolvency proceedings involving the Issuer or the Company)
shall all be chargeable to the Issuer and the Company and shall be secured by
this Mortgage, and the Issuer and the Company will also be responsible for any
deficiency (but, in the case of the Issuer, only to the extent set forth in
Section 7.10 hereof).

     SECTION 6.11.  OTHER ACTIONS BY THE HOLDER. Regardless of the happening of
the Event of Default, the Bank may institute and maintain such suits and
proceedings as it shall deem necessary or expedient to prevent any impairment of
the security under this Mortgage by

                                       45

<PAGE>

any acts which may be unlawful or in violation of this Mortgage, or to preserve
or protect the interests of the Bank.

     SECTION 6.12.  SALE IN ONE PARCEL. In case of a sale, the Project Facility
may be sold in one parcel. Should the Project Facility consists of more than one
parcel, in the even of a foreclosure of this Mortgage or any mortgage at any
time consolidated with this Mortgage, the Company and the Issuer agree that the
Bank shall be entitled to a judgment directing the referee appointed in the
foreclosure proceeding to sell all of the parcels constituting the Project
Facility at one foreclosure sale, either as a group or separately and that the
Company and the Issuer expressly waive any right that each may now have or
hereafter acquire to (i) request or require that the parcels be sold separately
or (ii) request, if the Bank has elected to sell parcels separately, that there
be a determination of any deficiency amount after any such separate sale or
otherwise require a calculation of whether said parcel or parcels separately
sold were conveyed for their "fair market value".

     SECTION 7.06.  SEVERABILITY. (A) If any provision of this Mortgage shall,
for any reason, be held or shall, in fact, be inoperative or unenforceable in

any of the Financing Documents which are or could be held to be in the nature of
interest exceed the maximum rate permitted to be charged under applicable law.
Should the Bank receive any payment which is or would be in excess of that

     SECTION 7.10.  NO RECOURSE; SPECIAL OBLIGATION. (A) The obligations and
agreements of the Issuer contained herein and in the other Financing Documents

Issuer in his individual capacity, and the members, officers, directors, agents
(other than the Company) and employees of the Issuer shall not be liable

<PAGE>

subject to any personal liability or accountability based upon or in respect
hereof or thereof or of any transaction contemplated hereby or thereby.

     (B)  The obligations and agreements of the Issuer contained herein and
therein shall not constitute or give rise to an obligation of the State of New
York or the Counties of Warren and Washington, New York, and neither the State
of New York nor the Counties of Warren and Washington, New York shall be liable
hereon or thereon, and further, such obligations and agreements shall not
constitute or give rise to a general obligation of the Issuer, but rather shall
constitute limited obligations of the Issuer payable solely from the revenues of
the Issuer derived and to be derived from the sale or other disposition of the
Mortgaged Property (except for revenues derived by the Issuer with respect to
the Unassigned Rights) and the other security pledged to the payment of the
Bonds.

     (C)  No order or decree of specific performance with respect to any of the
obligations of the Issuer hereunder or thereunder shall be sought or enforced
against the Issuer unless (1) the party seeking such order or decree shall first
have requested the Issuer in writing to take the action sought in such order or
decree of specific performance, and ten (10) days shall have elapsed from the
date of receipt of such request, and the Issuer shall have refused to comply
with such request (or, if compliance therewith would reasonably be expected to
take longer than ten [10] days, shall have failed to institute and diligently
pursue action to cause compliance with such request) or failed to respond within
such notice period, (2) if the Issuer refuses to comply with such request and
the Issuer's refusal to comply is based on its reasonable expectation that it
will incur fees and expenses, the party seeking such order or decree shall have
placed in an account with the Issuer an amount or undertaking sufficient to
cover such reasonable fees and expenses, and (3) if the Issuer refuses to comply
with such request and the Issuer's refusal to comply is based on its reasonable
expectation that it or any of its members, directors, officers, agents (other
than the Company) or employees shall be subject to potential liability, the
party seeking such order or decree shall (a) agree to indemnify, defend and hold
harmless the Issuer and its members, directors, officers, agents (other than the
Company) and employees against any liability incurred as a result of its
compliance with such demand, and (b) if requested by the Issuer, shall furnish
to the Issuer satisfactory security to protect the Issuer and its members,
officers, agents (other than the Company) and employees against all liability
expected to be incurred as a result of compliance with such request.

     (D)  The limitations on the obligations of the Issuer contained in this
Section 7.10 by virtue of any lack of assurance or indemnity required by
paragraph (C) hereof shall not be deemed to prevent the occurrence and full
force and effect of any Event of Default pursuant to Section 6.01 hereof.

     SECTION 7.11.  TAX LAWS. If any law or ordinance is enacted or adopted
which imposes a tax, either directly or indirectly, on this Mortgage, the

hereafter to be covered by this Mortgage or otherwise for carrying out the
intention of facilitating the performance of the terms of this Mortgage.

     SECTION 7.14.  SATISFACTION OF MORTGAGE. Upon the payment in full of all of
the amounts due under the Bonds, if (A) there is no Event of Default under the
Indenture, (B) the Issuer and the Company have performed and observed all the
covenants to be performed and observed hereunder and have performed all
obligations under the Indenture, the Installment Sale Agreement and the other
Financing Documents to which they are parties, and (C) the Company has paid or
caused to be paid to the Bank all sums of money due or to become due to it in
accordance with the terms and provisions hereof and of the other Financing
Documents to which it is a party, including, without limitation all
indemnification provisions, the Bank by acceptance of this Mortgage, agrees to
execute and deliver (after the expiration of the preference period under federal
bankruptcy law and any similar period under any similar statute affecting
creditors' rights), any and all instruments necessary and/or appropriate to
discharge the Lien of this Mortgage of record and to terminate the UCC-1
Financing Statements filed in connection with this Mortgage and the other
Financing Documents.

     SECTION 7.15   LIEN LAW. The Issuer and the Company will receive the
advances to be made hereunder subject to the trust provisions of Section 13 of
the Lien Law of the State of New York, and will hold the right to receive such
advances as a trust fund to be applied first for the purpose of paying the cost
of constructing the improvements to the Facility Parcel and will apply the same
first to such payment before using any part of the same for any other purpose,
but nothing herein shall be construed to impose upon the Bank any obligation to
see to the proper allocation of such advances by the Issuer.
