                                      -3-

                  (a) The parties hereby acknowledge and agree that, except as
provided in this Agreement, none of the Loan Documents have been modified,
amended, canceled, terminated, superseded, or otherwise rendered of no force and
effect.

                  (b) Borrower does hereby expressly reconfirm the conveyance
and grant of the security interests to Bank in the collateral to secure the
obligations under the Amended Note (the "Collateral"). Every other term,
condition, and provision contained in the Amended Note, the Mortgage, and the
other Loan Documents shall continue in full force and effect, except as modified
herein, and as so modified are hereby ratified and confirmed.

                  (c) Borrower hereby knowingly and, after receiving advice of
counsel, acknowledges and agrees that Borrower does not now have or know of any
basis for any claim in tort, contract or otherwise against Bank, its officers,

any of the Loan Documents including, without limitation, the Amended Note, the
Mortgage, or this Agreement, or which may arise out of the relationship between
it and Bank or any of the Bank Affiliates under any of the Loan Documents
including, without limitation, the Amended Note, the Mortgage or this Agreement
as of the date hereof, which period includes the execution and delivery of this
Agreement and the documents and instruments to be executed and delivered
pursuant to this Agreement.

                  (d) Borrower agrees to hold Bank harmless from and against any
and all liabilities, claims, demands, losses, damages, costs and expenses

of any covenant or agreement or the incorrectness or inaccuracy of any
representation and warranty of Borrower contained in this Agreement, any of the
Loan Documents or any document delivered to Bank by Borrower or any other person
on behalf of Borrower pursuant to the terms of this Agreement. This indemnity
shall survive the payment of the amounts contemplated by Paragraph 1 of this
Agreement and shall extend to the successors and assigns of Bank.

                  (e) All of the real and personal property described in the
Mortgage shall remain in all respects subject to the lien, charge and

Event of Default under the terms of this Agreement shall constitute a default

the time of any such default and under the documents evidencing any other loan
now existing or hereafter made by Bank to Borrower. The security interests,
liens and other rights and interests in and relative to any of the collateral

<PAGE>   5

                                      -4-

liabilities of Borrower to Bank, including, but not limited to, the liabilities
described in this Agreement, the Amended Note, the Mortgage and the other Loan
Documents, and, for the repayment thereof, Bank may resort to any security held
by it in such order and manner as it may elect.

                  (g) This Agreement shall inure to the benefit of and bind the
parties hereto and their respective successors and assigns.

         4.       Assignment or Transfer. Notwithstanding anything in the Loan
Documents to the contrary, Borrower agrees that Bank may assign, transfer, or
negotiate the Loan Documents and in such event all the provisions of the Loan
Documents (as the same may be modified hereby) shall inure to the benefit of and
may be exercised by or on behalf of the assignee, transferee, or holder and,
unless contrary to applicable law, all payments of principal and interest due
and to become due under the Amended Note and/or Mortgage (as modified hereby)
shall not thereafter be subject to any defense, counterclaim, or setoff which
Borrower may have against Bank.

         5.       Fees and Expenses. Borrower agrees to pay the reasonable legal
and other fees, commissions, costs, charges, taxes and other expenses and

applicable), appraisal fees, environmental consultants' fees, fees and charges
for surveys, examination of title to the Property, mortgage title insurance
premiums and charges for endorsements, mortgage taxes, documentary stamp taxes,
transfer taxes and all recording fees and charges Bank or any assignee,
transferee, or holder of the Loan Documents incurred as of September 29, 2000 in
the preparation, execution and delivery of this Agreement or in connection with
or incidental to any of the obligations of Borrower or rights of Bank or of such
assignee, transferee, or holder under the Loan Documents, by litigation or
otherwise; and all such fees and expenses shall be indebtedness under the
Amended Note and shall be secured by the Mortgage.

         6.       Waivers.

                  (a) Borrower waives presentment, demand, notice, protest,
notice of acceptance of this Agreement, notice of loans made, credit extended,
collateral received or delivered or other action taken in reliance hereon and
all other demands and notices of any description. With respect both to the
obligations evidenced by the Amended Note (the "Obligations") and the
Collateral, Borrower assents to any extension or postponement of the time of
payment or any other indulgence, to any substitution, exchange or release of the
Collateral, to the addition or release of any party or person primarily or
secondarily liable therefor, to the acceptance of partial payments thereon and
the settlement, compromising or adjusting of any thereof, all in such manner and
at such time or times as Bank may deem advisable in its sole and absolute
discretion. Bank shall have no duty as to the collection or protection of the
Collateral or any income thereon, nor as to the preservation of rights against
prior parties, nor as to the preservation of any rights pertaining thereto
beyond the safe custody thereof. Bank may exercise its rights with respect to
the Collateral without resorting, or regard to, other collateral or sources of
reimbursement for liability. Bank shall not be deemed to have waived any of its
rights upon

<PAGE>   6
                                      -5-

or under the Obligations or the Collateral unless such waiver be in writing and
signed by Bank. No delay or omission on the part of Bank in exercising any right
shall operate as a waiver of such right or any other right. A waiver on any one
occasion shall not be construed as a bar to any subsequent enforcement by Bank.
All rights and remedies of Bank with respect to the Obligations or the
Collateral, shall be cumulative and may be exercised singularly or concurrently.

                  (b) THE BORROWER AND EACH AND EVERY ENDORSER, GUARANTOR AND
SURETY OF THE OBLIGATIONS SECURED BY THIS AGREEMENT, AND EACH OTHER PERSON WHO
IS OR WHO SHALL BECOME LIABLE FOR ALL OR ANY PART OF THE OBLIGATIONS SECURED BY
THIS AGREEMENT, HEREBY ACKNOWLEDGE THAT THE TRANSACTION OF WHICH THIS AGREEMENT
IS A PART IS A COMMERCIAL TRANSACTION AND WAIVE THEIR RIGHTS TO NOTICE AND
HEARING UNDER CHAPTER 903a OF THE CONNECTICUT GENERAL STATUTES OR BY OTHER
APPLICABLE LAW WITH RESPECT TO ANY PREJUDGMENT REMEDY WHICH BANK MAY DESIRE TO
USE.

                  (c) BORROWER AND BANK MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY
AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM
BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY
OTHER LOAN DOCUMENTS CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY
COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR
ACTIONS OF ANY PARTY. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR BANK TO
ACCEPT THIS AGREEMENT AND MAKE THE LOAN.

                  (d) THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES HEREUNDER SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED AND
ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF CONNECTICUT (WITHOUT
GIVING EFFECT TO CONNECTICUT'S PRINCIPLES OF CONFLICTS OF LAW). BORROWER HEREBY
IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY CONNECTICUT STATE
COURT OR FEDERAL COURT SITTING IN THE STATE OF CONNECTICUT OVER ANY SUIT, ACTION
OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT, AND BORROWER HEREBY
AGREES THAT, IN ADDITION TO ANY METHODS OF SERVICE OF PROCESS PROVIDED FOR UNDER
APPLICABLE LAW, ALL SERVICE OF PROCESS IN ANY SUCH SUIT, ACTION OR PROCEEDING IN
ANY CONNECTICUT STATE COURT OR FEDERAL COURT SITTING IN THE STATE OF CONNECTICUT
MAY BE MADE BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, DIRECTED
TO BORROWER AT THE ADDRESS INDICATED ON THE COVER PAGE HEREOF, AND SERVICE SO
MADE SHALL BE COMPLETE TWO (2) DAYS AFTER THE SAME SHALL HAVE BEEN SO MAILED.

                                      -6-

         (e)      Setoff. Borrower and any Guarantor hereby grant to Bank a
lien, security interest and right of setoff as security for all liabilities and
obligations to Bank, whether now existing or hereafter arising, upon and against
all deposits, credits, collateral and property, now or hereafter in the
possession, custody, safekeeping or control of Bank or any entity under the
control of Fleet Financial Group, Inc., or in transit to any of them. Subject to
any agreement between Borrower and Bank, at any time, without demand or notice,
Bank may setoff the same or any part Thereof and apply the same to any liability
or obligation of Borrower and any Guarantor even though unmatured and regardless
of the adequacy of any other collateral securing the Loan. ANY AND ALL RIGHTS TO
REQUIRE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER
COLLATERAL WHICH SECURES THE LOAN, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH
RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER OR ANY
GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

         7.       Ratification of Obligations.

                  (a) The Borrower hereby ratifies and confirms its obligations
and liabilities under the Loan Documents, as may be modified herein, and
acknowledges and agrees that such obligations and liabilities shall continue in
full force and effect. Any default by the Borrower in any of the covenants,
conditions, provisions, stipulations or agreements herein shall, at the option
of Bank, or its successors and assigns, constitute a default under the Mortgage
and/or the Amended Note entitling Bank, or its successors or assigns to any or
all of the other remedies it or they may have thereunder.

                  (b) In confirmation of the hereinabove, Borrower hereby grants
and conveys to the Bank, with MORTGAGE COVENANTS, the Property; to have and to
hold the Property unto the Bank, its successors and assigns, forever in
accordance with the Amended Note and Mortgage and other Loan Documents, such
that if such sums due hereunder shall be paid and all other obligations of
Borrower under the Loan Documents shall be fully kept and performed, then the
Mortgage, as modified herein, shall be null and void; otherwise to remain in
full force and effect.

         8.       Severability. In the event any term or provision of this
Agreement or the application thereof to any person or circumstance shall, to any
extent, be held invalid or unenforceable, the remainder of this Agreement or the
application of such term or provision to persons or circumstances other than
those to which it is held invalid or unenforceable, shall be valid and
enforceable to the fullest extent permitted by law.
