                           --------------------------

$6,975,000.00                                                December    , 2001
                                                                      ---
                                                          Stamford, Connecticut

1. FOR VALUE RECEIVED, the undersigned, TECHNOLOGY DRIVE LLC, a Connecticut
limited liability company, with a notification address at 50 Inwood Drive, Rocky
Hill, Connecticut 06067 (the "Maker"), promises to pay to the order of WEBSTER
                              -----
BANK, a federal savings bank chartered under the laws of the United States (the
"Lender"), at its office located at City Place II, 185 Asylum Street, Hartford,
 ------
Connecticut 06103, or at such other place as the holder hereof (including the
Lender, hereinafter referred to as the "Holder"), may designate, the principal
                                        ------
sum of SIX MILLION NINE HUNDRED SEVENTY-FIVE THOUSAND DOLLARS ($6,975,000.00),
or so much thereof as has been advanced or is outstanding pursuant to the terms
of this Note, together with interest as set forth herein (the "Loan"), from the
                                                               ----
date of this Note until the entire principal balance has been paid. The
principal amount of this Note shall be advanced pursuant to requests for
advances submitted by Maker pursuant to that certain Construction Loan Agreement
of even date herewith between Maker and Lender (the "Loan Agreement"), and this
                                                     --------------
Note is subject to the terms and conditions of the Loan Agreement.

2. The principal amount outstanding under this Note will bear interest at a rate
per annum equal to the sum of (A) LIBOR in effect on each Reset Date plus (B)
                                                                     ----
two hundred thirty-seven and one-half (237.5) basis points.

For the purpose hereof, the following terms shall have the following meanings:

     "Business Day" shall mean any day on which commercial banks settle payments
     in U.S. dollars in New York City and London.

     The term "LIBOR" shall mean, as applicable to the Loan the rate per annum
     as determined on the basis of the offered rates for deposits in U.S.
     Dollars for a period of one calendar month which appears on the Telerate
     page 3750 as of 11:00 a.m. London time on the day that is two London
     Banking Days preceding the applicable Reset Date, provided, however, if the
     rate described above does not appear on the Telerate system on any
     applicable interest determination date, the LIBOR rate shall be the rate
     (rounded upward, if necessary, to the nearest one hundred-thousandth of a
     percentage point), determined on the basis of the offered rates for
     deposits in U.S. Dollars for a period of one calendar month which are
     offered by four major banks in the London interbank market at approximately
     11:00 a.m. London time, on the day that is two (2) London Banking Days
     preceding the applicable Reset Date as selected by Lender. The principal
     London office of each of the four major London banks will be requested to
     provide a quotation of its U.S. Dollar deposit offered rate. If at least
     two such quotations are provided, the rate for that date will be the
     arithmetic mean of the quotations. If fewer than two quotations are
     provided as requested, the rate for that date will be determined on the
     basis of the rates quoted for loans in U.S. Dollars to leading European
     banks for a

<PAGE>

     period one calendar month offered by major banks in New York City at
     approximately 11:00 a.m. New York City time, on the date that is two London
     Banking days preceding the applicable Reset Date. In the event that Lender
     is unable to obtain any such quotation as provided above, it will be deemed
     that LIBOR pursuant to the Loan cannot be determined. In the event that the
     Board of Governors of the Federal Reserve System shall impose a Reserve
     Percentage with respect to LIBOR deposits of Lender, then for any period
     during which such Reserve Percentage shall apply, LIBOR shall be equal to
     the amount determined above divided by an amount equal to 12 minus the
     Reserve percentage.

     "LIBOR Reserve Percentage" shall mean the maximum aggregate reserve
     requirement (including all basic, supplemental, marginal and other
     reserves) which is imposed on member banks of the Federal Reserve System
     against "Euro-currency Liabilities" as defined in Regulation D.

     "Reset Date" shall mean (i) the date of this Note, for the initial period
     from the date hereof through December 31, 2001, and (ii) the first (1st)
     day of each month thereafter, beginning on January 1, 2002 (but if any such
     day is not a Business Day, then the first succeeding day that is a Business
     Day shall instead apply, unless that day falls into the next calendar
     month, in which case the first preceding day that is a Business Day shall
     instead apply).

     LIBOR shall be adjusted (a) on each Reset Date, and (b) on the effective
     date of any change in the LIBOR Reserve Percentage. Holder shall give
     prompt notice to Maker of LIBOR as determined or adjusted in accordance
     herewith, which determination shall be conclusive absent manifest error.

     Each month during the term of the Loan, Lender shall provide Maker with a
     bill or statement indicating the amount of interest accrued under the Loan;
     it being agreed however, that in no event shall Lender's failure to furnish
     such bill or statement relieve Maker of any liability or obligation
     whatsoever arising out of or in connection with the outstanding
     indebtedness of this Note or the Loan.

     If Holder determines (which determination shall be final and conclusive)
     that, by reason of circumstances affecting the eurodollar market generally,
     deposits in dollars (in the applicable amounts) are not being offered to
     banks in the eurodollar market for the selected term, or adequate means do
     not exist for ascertaining LIBOR, then Holder shall give notice thereof to
     Maker. Thereafter, until Holder notifies Maker that the circumstances
     giving rise to such suspension no longer exists, (a) the availability of
     LIBOR shall be suspended, and (b) the interest rate for all amounts
     outstanding under this Note shall be converted on the next Reset Date to a
     rate of interest per annum equal to the Prime Rate (the "Base Rate"). For
                                                              ---------
     purposes hereof, the term "Prime Rate" shall mean the rate publicly
     announced by Holder from time to time as its Prime Rate. The Prime Rate is
     determined from time to time by Holder as a means of pricing some loans to
     its borrowers. The Prime Rate is not tied to any external rate of interest
     or index, and does not necessarily reflect the lowest rate of interest
     actually

                                       2

<PAGE>

     charged by Holder to any particular class or category of customers. If and
     when the Prime Rate changes, the rate of interest with respect to any
     amounts hereunder to which the Base Rate applies will change automatically
     without notice to Maker, effective on the date of any such change.

     In addition, if, after the date of this Note, Holder shall determine (which
     determination shall be final and conclusive) that any enactment,
     promulgation or adoption of or any change in any applicable law, rule or
     regulation, or any change in the interpretation or administration thereof
     by a governmental authority, central bank or comparable agency charged with
     the interpretation or administration thereof, or compliance by Holder with
     any guideline, request or directive (whether or not having the force of
     law) of any such authority, central bank or comparable agency shall make it
     unlawful or impossible for Holder to make or maintain or fund loans bearing
     interest based on LIBOR, Holder shall notify Maker. Upon receipt of such
     notice, until Holder notifies Maker that the circumstances giving rise to
     such determination no longer apply, (a) the availability of LIBOR shall be
     suspended, and (b) the interest rate on all amounts outstanding under this
     Note shall be converted to the Base Rate either (i) on the next Reset Date
     if Holder may lawfully continue to maintain amounts outstanding hereunder
     to such day at a rate of interest based on LIBOR, or (ii) immediately if
     Holder may not lawfully continue to maintain amounts outstanding hereunder
     at a rate of interest based on LIBOR.

     Interest shall be computed daily and payable monthly in arrears on the
     basis of a 360 day year and for the actual number of days in each interest
     period, together with all taxes (except income taxes) levied or assessed
     against the Holder on this Note or the debt evidenced hereby, and together
     with all costs, expenses, reasonable attorneys' and professionals' fees
     incurred in any action to collect the indebtedness of this Note, to
     foreclose the mortgage or any security interest granted to the Holder
     securing this Note or in protecting or sustaining the lien of any mortgage
     or any security agreement or other agreement or in any litigation or
     controversy arising from or connected with any mortgage, security agreement
     or other agreement or this Note.

3. From the date hereof and until December 31, 2002 (the "Conversion Date"),
                                                          ---------------
Maker shall pay interest only on the principal amount at the LIBOR rate plus
237.5 basis points. Thereafter, beginning on January 1, 2003, and on the first
(1st) day of each month thereafter, Maker shall make monthly payments of
principal and interest, in an amount sufficient to fully amortize the
outstanding principal balance of this Note in monthly installments based upon a
fifteen (15) year amortization schedule, as more particularly described on
Schedule A attached hereto. Unless sooner accelerated or paid, all outstanding
----------
principal, together with all accrued and unpaid interest, late charges, costs
and expenses shall be due and payable in full on or before December 31, 2009
(the "Maturity Date").
      -------------

4. The Holder shall make advances of the principal amount of this Note in
installments upon the request of the Maker, pursuant to the terms and conditions
set forth below and as set forth in the Loan Agreement of even date. All amounts
as have been, or shall be advanced, to the Maker, less

                                       3

<PAGE>

any repayments, together with interest thereon, taxes, costs, expenses and
reasonable attorneys' fees, reasonable paralegals' fees and disbursements in
connection therewith and all other charges made pursuant to this Note shall be
due under this Note. Advances and payments on this Note shall be recorded on a
schedule or on the Maker's statements.

5. At any time prior to the Conversion Date, Maker shall have the option to
enter into and maintain during the term of this Note, a Swap Agreement to hedge
the interest rate expense pursuant to that certain ISDA Master Agreement with
the Lender or another acceptable counterparty.

6. Maker shall have the right to prepay at any time and from time to time, in
whole or in part, without penalty, any amount owing under this Note which is
accruing interest based on the Base Rate. If maker prepays (whether voluntary,
on default or otherwise) all or any part of this Note which is accruing interest
based on LIBOR on a day other than the next applicable Reset Date, Maker shall
pay to Holder, on demand therefor, all amounts due pursuant to Paragraph 7
below, including the cost of prepayment, if any.

7. Maker shall pay to Holder, on written demand therefor, together with the
written evidence of the justification therefore, all direct costs incurred,
losses suffered or payments made Holder by reason of any change in law or
regulation or its interpretation imposing any reserve, deposit, allocation of
capital, or similar requirement (including without limitation, Regulation D of
the Board of Governors of the Federal Reserve System) on Holder, its holding
company or any of their respective assets relating to taking LIBOR deposits. In
addition, Maker agrees to indemnify Holder against any liabilities, losses or
expenses (including loss of margin, any loss or expense sustained or incurred in
liquidating or employing deposits from third parties, and any loss or expense
incurred in connection with funds acquired to) effect, fund or maintain any
advance (or any part thereof) bearing interest based on LIBOR which Holder
sustains or incurs as a consequence of either (i) Maker's failure to make a
payment on the due date thereof; (ii) Maker's revocation (expressly, by later
inconsistent notices or otherwise) in whole or in part of any notice given to
Holder to request, convert, renew or prepay any principal amount, or (iii)
Maker's payment, prepayment or conversion of any principal amount bearing
interest based on LIBOR on a day other than the next applicable Reset Date.

8. The Maker agrees that if (i) Maker shall fail to make any payments of
principal and/or interest required to be paid under the terms of this Note
within three (3) Business Days of the date when due, or (ii) Maker shall fail to
observe or perform any other term, covenant or condition of this Note on Maker's
part to be observed or performed, and Maker shall fail to remedy such failure
within fifteen (15) days after written notice by Lender to Maker of such
failure, or if such failure is of such a nature that it cannot with due
diligence be completely remedied within such fifteen (15) day period, and Maker
shall not commence within said period of fifteen (15) days, or shall not
thereafter diligently prosecute to completion, all steps necessary to remedy
such failure, for an aggregate period not to exceed sixty (60) days after
written notice by Lender to Maker of such failure, or (iii) an Event of Default
(as defined in any other documents, instruments or agreements which evidence,
secure or guaranty the outstanding indebtedness of this Note, including, without
limitation, that certain Open-End Construction Mortgage Deed and Security
Agreement (the "Mortgage") or such other
                --------

<PAGE>

instrument, of this date between the Holder and the Maker occurs and continues
beyond all applicable cure periods set forth in the Mortgage, if any, or (iv)
the occurrence of any event or circumstance consisting an Event of Default under
any of the terms or provisions of the ISDA Master Agreement of event date
between maker and lender; or under any Credit Support Document as defined by
said Master Agreement, or (v) Maker or any Guarantor of the obligations under
this Note shall fail to perform or comply with the terms, covenants, or
conditions of any and all other obligations, indebtedness or financing
accommodations extended to, or on behalf of, the Maker or such Guarantor by the
Holder (collectively, the "Obligations"), then, upon the occurrence of any such
                           -----------
event which shall continue beyond the applicable notice and cure periods, if any
(collectively, an "Event of Default"), the entire indebtedness with accrued
                   ----------------
interest thereon due under this Note shall, at the option of the Holder,
accelerate and become immediately due and payable without notice.

9. Within the limits set forth below, and provided (i) the Maker is in
compliance with all the terms and conditions of this Note, (ii) no Event of
Default has occurred and is continuing and has not been cured within the
applicable grace period, (iii) no condition exists which would constitute an
Event of Default but for the giving of notice, the passage of time or both, and
(iv) the Holder has not accelerated payment under this Note, the Holder shall
make advances under this Note to the Maker in accordance with the terms and
conditions set forth below, provided, however, that in no event shall the
maximum principal amount advanced under this Note exceed the amount of
$6,975,000.00 at any time:

     (a) The Maker covenants and agrees that the proceeds of this Note shall be
used as follows: for hard construction costs to build an approximately 98,500
square foot one-story office and research and development building (the
"Project") at 8 Technology Drive, Meadow Business Park, Wallingford,
 -------
Connecticut, (the "Property"), including, but not limited to, the costs to
                   --------
acquire the Property, all hard and soft costs associated with the construction
of the improvements to be located on the Property, interest due on the Loan
during construction and all other costs, including, but not limited to, legal
fees, Lender fees, and third party fees associated with the Loan and contingency
costs, provided all such costs are contained in a construction budget approved
by Lender.

     (b) All advances for the construction costs of the Project shall be
approved by the Holder and subject to evidence reasonably satisfactory to Holder
that such costs have been incurred and/or performed by Borrower pursuant to
approved costs.

     (c) Prior to the disbursement of any Loan proceeds, Maker shall provide
evidence that it has obtained all necessary municipal approvals and all other
permits, licenses and other government and development agency approvals
necessary for the portion of the Project then completed and that all utility
services required for the use, occupancy, and operation of the Property and the
Project are or will be available.

                                       5

<PAGE>

     (d) The Maker specifically understands and agrees that all advances to be
disbursed under this Note shall be subject to all of the terms and conditions as
set forth in the Construction Loan Agreement of even date herewith.

10. Maker shall establish a Project operating account (the "Operating Account")
                                                            -----------------
with the Holder. The Maker hereby authorizes the Holder to deposit all advances
to the Maker under this Note directly into the Operating Account. Under no
circumstances shall advances be made to the Maker after the applicable Maturity
Date. The obligation of the Holder to make advances under this Note is further
subject to the conditions set forth in the Loan Agreement.

11. In the event that any federal, state or local law is passed or a final
decision of any court is rendered which in any way impairs the Holder's ability
to vary the Note Rate in accordance with the terms hereof the entire
indebtedness and any accrued interest thereon under the Note shall become
immediately due and payable after giving Maker sixty (60) days written notice
and opportunity to pay the amount due under the Note in full.

12. The Maker agrees that upon the occurrence of an Event of Default, or after a
court ordered judgment with respect to the Loan after the applicable Maturity
Date, the indebtedness of this Note shall bear interest at an annual rate of
four percent (4.0%) above the then applicable rate under the Note (the "Default
                                                                        -------
Rate"). Maker acknowledges that: (i) such additional rate is a material
----
inducement to Holder to make the loan evidenced by this Note; (ii) Holder would
not have made the loan in the absence of the agreement of the Maker to pay such
additional Default Rate; (iii) such additional Default Rate represents
compensation for increased risk to Maker that the indebtedness due under this
Note will not be repaid; and (iv) such additional Default Rate is not a penalty
and represents a reasonable estimate of (a) the cost to Holder in allocating its
resources (both personal and financial) to the on-going review, monitoring,
administration and collection of the loan and (b) compensation to Holder for
losses that are difficult to ascertain.

13. If the Holder receives any payment, or part thereof, more than ten (10) days
after its due date, the Holder shall assess the Maker with a late charge of five
percent (5.0%) of the total amount of such late payment to defray the extra
expense involved in handling such delinquent payment. Such charge shall be in
addition to, and not in lieu of, any other remedy Holder may have and shall be
in addition to, and not in lieu of, Maker's obligation to pay any fees and
charges of any agents or attorneys employed upon the occurrence of an Event of
Default hereunder.

14. Maker and any Guarantor hereby grant to Lender, a continuing lien, security
interest and right of setoff as security for all liabilities and obligations to
Lender 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 Lender or any entity under the control of Webster Bank
and its successors and assigns or in transit to any of them. At any time
following an Event of Default, without demand or notice (any such notice being
expressly waived by Maker), Lender may setoff the same or any part thereof and
apply the same to any liability or obligation of Maker and any Guarantor to
Lender even though unmatured and regardless of the adequacy of any other
collateral

                                       6

securing the Loan. ANY AND ALL RIGHTS TO REQUIRE LENDER TO EXERCISE ITS RIGHTS
OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURED THE LOAN PRIOR TO
EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER
PROPERTY OF MAKER OR ANY GUARANTOR ARE HEREBY KNOWINGLY, VOLUTARILY AND
IRREVOCABLY WAIVED.

15. The Maker gives the Holder a lien and right of setoff for all of the Maker's
liabilities upon and against all the deposits, credits, collateral and property
of the Maker now or hereafter in the possession or control of the Holder or in
transit to it. The Holder may, upon the occurrence of an Event of Default, apply
or set off the same, or any part thereof, to any liability of the Maker even
though unmatured.

16. The failure by the Holder to insist upon the strict performance by the Maker
of any terms and provisions contained herein shall not be deemed to be a waiver
of any terms and provisions herein, and the Holder shall retain the right
thereafter to insist upon strict performance by the Maker of all the terms and
provisions of this Note or any document securing the repayment of this Note.

17. If the proceeds from an insurance policy are paid to the Holder pursuant to
the Loan Documents or any other agreement executed in connection herewith, the
Holder shall apply such proceeds in accordance with the Mortgage.

18. This Note shall be governed by and construed in accordance with the laws of
the State of Connecticut. The Maker consents to the jurisdiction of the
appropriate court within the State of Connecticut with respect to any claims or
disputes arising out of the enforcement of this Note.

19. THE MAKER ACKNOWLEDGES THAT THE LOAN EVIDENCED BY THIS NOTE IS A COMMERCIAL
TRANSACTION AND WAIVES ITS RIGHTS TO NOTICE AND HEARING UNDER CHAPTER 903a OF
THE CONNECTICUT GENERAL STATUTES, OR AS OTHERWISE ALLOWED BY ANY OTHER STATE OR
FEDERAL LAW WITH RESPECT TO ANY PREJUDGMENT REMEDY WHICH THE HOLDER DESIRES TO
USE, AND FURTHER, WAIVES DILIGENCE, DEMAND, PRESENTMENT FOR PAYMENT, NOTICE OF
NONPAYMENT, PROTEST AND NOTICE OF PROTEST, AND NOTICE OF ANY RENEWALS OR
EXTENSIONS OF THIS NOTE. THE MAKER ACKNOWLEDGES THAT IT MAKES THIS WAIVER
KNOWINGLY, VOLUNTARILY, WITHOUT DURESS AND ONLY AFTER EXTENSIVE CONSIDERATION OF
THE RAMIFICATIONS OF THIS WAIVER WITH ITS ATTORNEYS. MAKER FURTHER CONSENTS TO
THE ISSUANCE OF ANY SUCH PREJUDGMENT REMEDIES WITHOUT A BOND AND AGREES NOT TO
REQUEST OR FILE MOTIONS SEEKING TO REQUIRE THE POSTING OF A BOND UNDER PUBLIC
ACT 93-431 IN CONNECTION WITH LENDER'S EXERCISE OF ANY PREJUDGMENT REMEDIES.

20. THE MAKER WAIVES TRIAL BY JURY IN ANY COURT IN ANY SUIT, ACTION, PROCEEDING
OR ANY MATTER ARISING IN CONNECTION WITH OR IN ANY WAY RELATED TO THIS NOTE OR
THE FINANCING TRANSACTION OF WHICH THIS NOTE IS

                                       7

A PART OR THE DEFENSE OR ENFORCEMENT OF ANY OF THE HOLDER'S RIGHTS AND REMEDIES
IN CONNECTION THEREWITH. THE MAKER ACKNOWLEDGES THAT IT MAKES THIS WAIVER
KNOWINGLY, VOLUNTARILY, WITHOUT DURESS AND ONLY AFTER EXTENSIVE CONSIDERATION OF

21. The Maker acknowledges that the obligations under this Note are irrevocable,
absolute and unconditional and Maker hereby waives demand, presentment, protest,
notice of protest, notice of dishonor, collection, notice of nonpayment and all
notices of a like notice.

22. If one or more of the provisions of this Note shall for any reason be held
to be invalid, illegal or unenforceable, in whole or in part, or in any respect,
or if any one or more of the provisions of this Note shall operate, or would
prospectively operate, to invalidate this Note, then such provision or
provisions only shall be deemed to be null and void and of no force or effect
and shall not affect any other provision of this Note, and the remaining
provisions of this Note shall remain operative and in full force and effect,
shall be valid, legal and enforceable, and shall in no way be affected
prejudiced or disturbed thereby.

of all obligations under this Note. This Note shall be governed by and construed
in accordance with the laws of the State of Connecticut. The Maker consents to

                                       I.
                             COVENANTS OF MORTGAGOR

     1.1. Competence to Execute Loan Documents. Mortgagor is a limited liability
          ------------------------------------
company in existence in the State of Connecticut and has full power and
authority to execute and deliver the Note, this Mortgage, all Financing
Agreements (as hereafter defined) and all other agreements and documents
required of Mortgagor, to Mortgagee, and the execution and delivery of the same
is not in violation of and will not result in a default (or with the giving of
notice or the passage of time, or both, would constitute such a default)
pursuant to any agreements or understanding, whether written or oral, which
Mortgagor has or may have with any person or entity. Mortgagor's execution and
delivery of the same has been duly authorized.

     1.2. Legal Tender, Joint and Several Liability and Application of Payments.
          ---------------------------------------------------------------------
Mortgagor shall pay the entire Indebtedness stated in the Note, including, but
not limited to, all outstanding principal and the interest thereon in lawful
money of the United States at the times and in the manner set forth in the Note
and herein.

     Unless applicable law provides otherwise, all payments received by
Mortgagee under the Note and this Mortgage, at the option of Mortgagee, shall be
applied by Mortgagee in the following order:

                                       4

<PAGE>

          (a) to the then outstanding charges and expenses incurred by Mortgagee
in sustaining and/or enforcing any security granted to Mortgagee in connection
with the Note and as otherwise provided herein and in the Financing Agreements;

          (b) to the then outstanding late charges imposed against Mortgagor in
connection with the loan evidenced by the Note;

          (c) to any unpaid and accrued interest; and then

          (d) to the outstanding principal Indebtedness of Mortgagor in favor of
Mortgagee.

     1.3. Taxes, Assessments and Other Charges. At Mortgagee's option, Mortgagor
          ------------------------------------
shall pay to Mortgagee at the time of each installment of principal and interest
due under the Note, and commencing with the first payment due after the date of
such request, an amount which represents a sum equal to (a) the amount of the
next installment of taxes and assessments levied or assessed against the
Premises, and/or (b) the premiums which will next become due on the insurance
policies required by the Mortgage, all in amounts as estimated by Mortgagee,
less all sums already paid therefor or deposited with Mortgagee for the payment
thereof, divided by the number of payments to become due before one (1) month
prior to the date when such taxes and assessments and/or premiums, as
applicable, will become due, such sums to be held by Mortgagee to pay the same
when due. If such escrow funds are not sufficient to pay such taxes and
assessments and/or insurance premiums, as applicable, as the same become due,
Mortgagor shall pay to Mortgagee, upon request, such additional amounts as
Lender shall estimate to be sufficient to make up any deficiency. No amount paid
to Mortgagee hereunder shall be deemed to be trust funds but may be commingled
with general funds of Mortgagee and no interest shall be payable thereon. Upon
the occurrence of an Event of Default (as that term is defined herein),
Mortgagee shall have the right, at its sole discretion, to apply any amounts so
held against the Liabilities (as that term is defined herein). If Mortgagor is
not required to pay tax escrows pursuant to this Section, Mortgagor shall
promptly provide to Mortgagee on a semi-annual basis (if such taxes or
assessments are payable semi-annually) or on a quarterly basis (if such taxes or
assessments are payable quarterly), copies of receipted tax bills, cancelled
checks or other evidence satisfactory to Mortgagee evidencing that such taxes
and assessments have been timely paid. Mortgagor agrees that all amounts
currently held in escrow by Mortgagee in connection with this Mortgage shall be
included and considered part of the escrow described above for all purposes.
Following Mortgagor's full repayment of the Loan, Mortgagee shall return to
Mortgagor any escrowed amount held by Mortgagee that is not required to be paid
pursuant to this Section 1.3.

     1.4. Insurance.
          ---------

          (a) Hazard Insurance. Mortgagor shall keep the Mortgaged Property and
              ----------------
any and all alterations, rebuilding, replacements and additions thereto, insured
for the benefit of Mortgagee pursuant to policies which shall be written on a
broad form Builder's All Risk, Completed Value non-reporting form, which shall
include coverage therein for "completion and/or premises occupancy" and provide
coverage of not less than coverage encompassed by Fire, Extended Coverage and
Vandalism and Malicious Mischief perils broadened to so-called "Direct or All
Risk of Physical Loss" (hereinafter collectively called the "Hazards and
Risks"), all in formats reasonably approved by Mortgagee and in an amount
equivalent to one hundred percent (100%) of the full insurable value thereof
(excluding foundation and site improvements) with such insurance to provide for
the full replacement cost excluding the footings and foundations below the lower
basement floor undersurface, or if there is no basement,

                                       5

<PAGE>

that surface which is below ground level; without deduction for depreciation.
All policies shall also include an "agreed amount endorsement." Such insurance
shall not contain any clause which would result in the insured thereunder being
required to carry insurance with respect to the property covered thereby in an
amount equal to the minimum specific percentage of the full replacement cost of
such property in order to prevent the insured therein named from becoming a
co-insurer of any loss under such policy. All insurance herein provided for
shall cite Mortgagee as a first mortgagee/loss payee and shall be obtained by
Mortgagor (notwithstanding the procurement of other insurance policies by other
persons or parties and relating to the Mortgaged Property) and carried in
companies reasonably approved by or reasonably satisfactory to Mortgagee.
Notwithstanding the foregoing, Mortgagor shall have the right of free choice in
the selection of the agent or insurer through or by which the insurance required
hereunder is to be placed; provided, however, said insurer must be authorized to
write such insurance in the State of Connecticut, must have a licensed resident
agent in this State and must have, at all times while this Mortgage is in
effect, a general policyholder's rating of at least A-12 in Best's latest rating
guide. All policies, including additional and renewal policies, shall contain an
agreement by the insurer that such policy shall not be modified or cancelled
without at least thirty (30) days prior written notice to Mortgagee, and all
renewal policies, marked premium paid, shall also be delivered to Mortgagee at
least thirty (30) days before the expiration thereof. All policies, including
additional and renewal policies, shall be payable, in case of loss or damage, to
Mortgagee as the first mortgagee, and shall contain the standard mortgage
endorsement and non-contributing mortgagee clause as well as standard waiver of
subrogation endorsement, and waiver of other endorsements, as Mortgagee may
reasonably require from time to time, all to be in form reasonably acceptable to
Mortgagee and shall be supplied to Mortgagee together with, at Mortgagee's sole
discretion, (i) a paid receipted bill for a minimum of a one year premium or
(ii) a paid receipted bill issued on a monthly basis evidencing the Mortgagor's
installment payment of the premium due for such insurance coverage. If Mortgagee
shall in any manner acquire title to the Mortgaged Property, it shall thereupon
become the sole and absolute owner of all insurance policies held by or required
hereunder to be delivered to Mortgagee, with the sole right to collect and
retain all unearned premiums and dividends. In the event of any loss, Mortgagor
will give immediate notice thereof to Mortgagee. Mortgagor hereby authorizes
Mortgagee, at its option, to collect, adjust and compromise any losses under any
of the insurance policies after deducting the costs of collection, to apply the
proceeds, at Mortgagee's sole option, as follows: (i) as a credit upon the
indebtedness secured hereby, whether or not the same shall be then due and
payable (except to the extent the amount of the casualty is determined to be
less than $150,000.00, in which event Mortgagor shall be obligated to use such
proceeds to repairing or restoring the Mortgaged Property), or (ii) to repairing
or restoring the Mortgaged Property or any part thereof, in which event,
Mortgagee shall not be obligated to see to the proper application thereof, nor
shall the amount so released or used be deemed a payment on any Indebtedness as
secured hereby and, if any amounts are applied to principal, they shall be
applied to installments in inverse order of maturity. The Mortgagee reserves the
right to increase the amount of any insurance coverage required hereunder to an
amount deemed reasonably necessary by the Mortgagee and to approve the form and
content of all insurance policies evidencing such coverage. Any failure on the
part of the Mortgagee to secure physical evidence of any insurance required
herein shall not relieve the Mortgagor of its responsibilities hereunder.

          (b) Liability Insurance. Mortgagor shall obtain, carry and maintain
              -------------------
such comprehensive casualty, general liability and indemnity insurance,
including, but not limited to, Workers' Compensation insurance as may be
reasonably required from time to time by Mortgagee in forms and with companies
reasonably approved by Mortgagee, and in an amount of not less than $3,000,000
for bodily injury and/or property damage liability written on an occurrence
basis with a broad form endorsement. Such insurance policies, including renewals
thereof, shall be deposited with Mortgagee and shall contain a provision
designating Mortgagee as an additional insured party and provide for not less

                                       6

<PAGE>

than thirty (30) days written notice to Mortgagee prior to any cancellation
thereof or material change therein.

          (c) Other Insurance. Mortgagee may, at its option, require Mortgagor
              ---------------
to obtain additional insurance in forms, amounts, substance and with companies,
institutions or persons reasonably satisfactory to Mortgagee. Such insurance
shall provide coverage for, but not be limited to: earthquakes, including
subsidence; errors and omissions; fidelity bond insurance; and/or such other
insurance reasonably requested by Mortgagee from time to time. If at any time,
the Mortgaged Property shall be deemed to be "nonconforming" due to the
enactment of any building code, ordinance or regulation, Mortgagor shall
immediately insure the Mortgaged Property against: (i) contingent liability from
the operation of any such building laws; (ii) demolition insurance; (iii)
increased cost of construction insurance; and (iv) increased time to rebuild
insurance protection, all in such formats and amounts as shall be satisfactory
to Mortgagee.

          If, at any time during the term of this Mortgage, including any
extensions thereof, the area in which the Premises, or any part thereof, is
located is designated as a "flood prone" area pursuant to the Flood Disaster
Protection Act of 1973, or any amendment or supplements thereto, or if such area
is identified on official flood maps published by the Federal Emergency and
Management Agency as either an "A," "A1-30," "AE," "A99," "AO," "V," "V1-30,"
"VE," "VO," "M," or "E," "flood" area/zone, then, in such event, Mortgagor shall
promptly obtain flood insurance (or a formal policy application and evidence as
to its payment of the full initial annual premium therefor in the event such
determination is made immediately prior to the date hereof and during such
initial insurance acquisition waiting period) in an amount equal to that
coverage available pursuant to regulations adopted from time to time by the
National Flood Insurance Program or the amount of indebtedness hereby secured,
whichever is less, and shall otherwise comply with the National Flood Insurance
Program as set forth in the Flood Disaster Protection Act of 1973. Mortgagor
further covenants and agrees to fully comply with the requirements of the
National Flood Insurance Act of 1968 and the Flood Disaster Protection Act of
1973, as the same may be amended from time to time, and any other law, order,
rule, ordinance or regulation concerning flood insurance, to the extent that the
same apply to the Premises, or any part thereof.

     1.5. Eminent Domain. In the event that the whole or any part of the
          --------------
Mortgaged Property shall be taken by eminent domain, or in the event of any
alteration of the grade of any street or highway, or of any other injury to or
decrease in value of the Mortgaged Property, or in the event of the
reacquisition of the whole or any part of the Mortgaged Property pursuant to the
terms of any redevelopment plan or agreement affecting the Mortgaged Property or
if any agreement shall be made between Mortgagor and any entity vested with the
power of eminent domain, any and all awards and payments on account thereof
shall be deposited with Mortgagee as further security for the Loan. Mortgagor
shall give Mortgagee immediate notice of the actual or threatened commencement
of any of the foregoing proceedings, and shall deliver to Mortgagee copies of
all papers served in connection with any such proceedings. The Mortgagee shall
have the right to intervene and participate in any proceedings for and in
connection with any such taking, unless such intervention shall be prohibited by
the court having jurisdiction over such taking, in which event Mortgagor shall
consult with Mortgagee in connection with such proceedings; and Mortgagor shall
not enter into any agreement with regard to the Mortgaged Property or any award
or payment on account thereof unless Mortgagee shall have consented thereto in
writing, which consent shall not be unreasonably withheld. Mortgagee shall have
the right, at Mortgagee's option, to adjust, compromise or settle the claim for
any such award or payment, to collect, receive and retain the proceeds thereof
all of which shall be applied to the Loan, and to give proper receipts therefor.
Mortgagor further agrees, on request, to make, execute, and deliver to Mortgagee
any and all assignments and other instruments, as Mortgagee may reasonably
require, to confirm or assign all

                                       7

<PAGE>

such awards and payments to Mortgagee free and clear of any and all encumbrances
of any nature whatsoever.

          Notwithstanding any such taking, alteration of grade, other injury to
or decrease in value of the Mortgaged Property, or reacquisition of title, or
agreement, Mortgagor shall continue to pay interest on the principal sum secured
hereby at the rate provided in the Note, and to make any and all payments
required by said Note and this Mortgage. Any reduction in the principal sum
resulting from the application by Mortgagee of such award or payment as
hereinafter set forth shall be deemed to take effect only on the date of such
application. The proceeds of any award or payment, after deducting the expenses
of collection, including, but not limited to, the counsel fees, other costs and
disbursements, incurred by Mortgagee, may be applied by Mortgagee, at its
option, toward payment of the indebtedness secured hereby whether or not the
same shall be then due or payable (and, if any portion thereof is applied to the
principal of the Note, it will be applied in inverse order of maturity), or be
paid over wholly or in part to Mortgagor for the purposes of altering or
restoring any part of the Mortgaged Property which may have been damaged as a
result of any such taking, alteration of grade, or other injury to the Mortgaged
Property, or for any other purpose or object satisfactory to Mortgagee, but
Mortgagee shall not be obligated to see to the proper application of any amount
paid over to Mortgagor, nor shall the amount so paid over to Mortgagor be deemed
a payment on any indebtedness secured hereby.

          If prior to the receipt by Mortgagee of such award or payment, the
Mortgaged Property shall have been sold on foreclosure of this Mortgage,
Mortgagee shall have the right to receive said award or payment to the extent of
the debt secured by this Mortgage remaining unsatisfied after such sale of the
Mortgage Property, with interest thereon at the rate set forth in the Note,
whether or not a deficiency judgment on this Mortgage shall have been sought or
recovered or denied, and to the extent of the counsel fees, costs and
disbursements incurred by Mortgagee in connection with the collection of such
award or payment.

     1.6. Insurance Escrow. Mortgagor agrees, after an Event of Default and at
          ----------------
the option of Mortgagee, to add to each such installment an additional amount
reasonably estimated by Mortgagee to be sufficient to enable Mortgagee to pay
the premiums that will next become due and payable on the policies of fire,
hazard, or other insurance to be obtained pursuant to this Mortgage. Any
deficiencies because of the insufficiency of such additional payments shall be
promptly deposited by Mortgagor with Mortgagee upon demand by Mortgagee. No
trust relationship shall exist between Mortgagor and Mortgagee as to said funds
so deposited, and said funds may be co-mingled with Mortgagee's other funds, and
no interest shall be paid by Mortgagee to Mortgagor for any funds so deposited.
After the occurrence of an Event of Default hereunder, Mortgagee, at its option
at any time after such default, may apply the balance remaining of said funds so
deposited, as a credit against the Indebtedness in such manner as Mortgagee may
determine.

     1.7. Statement on Encumbrances. Upon request by Mortgagee, Mortgagor shall
          -------------------------
obtain from all persons hereafter having or acquiring any interest in or
encumbrance on the Mortgaged Property or any part thereof, a writing, duly
acknowledged and stating the nature and extent of such interest or encumbrance
and that the same is subordinate to this Mortgage and that no offsets or
defenses exist in favor thereof against this Mortgage or the Note secured
hereby, and Mortgagor shall deliver such writing to Mortgagee.

     1.8. Books, Records and Accounts. Mortgagor will keep and maintain or will
          ---------------------------
cause to be kept and maintained proper and accurate books, records and accounts
reflecting all items of income and expense in connection with the ownership and
operation of the Mortgaged Property or any part thereof,

                                       8

<PAGE>

including, but not limited to, any services, equipment or furnishings provided
in connection therewith, whether such income or expenses be realized by
Mortgagor or by any other person or entity whatsoever and will furnish the same
to Mortgagee upon request. Mortgagee or its designee shall have the right from
time to time at all times during normal business hours to examine such books,
records and accounts at the office of Mortgagor or other person or entity
maintaining such books, records and accounts and to make such copies or extracts
thereof as Mortgagee shall desire, provided that upon request of Mortgagor,
Mortgagee shall execute a confidentiality agreement in form satisfactory to
Mortgagee to the extent required by applicable securities laws.

     1.9. Right to Enter Premises. Mortgagor hereby grants to Mortgagee and any
          -----------------------
persons authorized by Mortgagee the unobstructed right to enter and inspect the
Mortgaged Property at all times during normal business hours after at least 48
hours prior notice to Mortgagor, except in the case of an emergency in which
case no prior notice is required.

     1.10. Protection of Mortgage Lien. Mortgagor shall pay all costs and
           ---------------------------
expenses, including reasonable counsel fees, incurred by Mortgagee in
protecting, sustaining or enforcing the lien of this Mortgage. Mortgagor shall
indemnify and hold Mortgagee harmless from all such costs and expenses,
including, but not limited to, counsel fees, recording fees, costs of title
searches, continuation of abstract and preparation of survey, incurred by reason
of any action, suit, proceeding, hearing, motion or application before any court
or administrative body in which Mortgagee may be a party by reason hereof,
including, but not limited to, condemnation, bankruptcy and administrative
proceedings, as well as any other proceedings wherein proof of claim is required
to be filed or in which it becomes necessary, in Mortgagee's sole opinion, to
defend or uphold the terms and priority of this Mortgage. All money paid or
expended by Mortgagee in that regard, together with interest thereon from the
date of such payment at the rate set forth in the Note, shall be additional
indebtedness secured hereby and shall be immediately and without notice due and
payable to Mortgagee by Mortgagor.

     1.11. Waiver of Liens. Mortgagor shall furnish to Mortgagee all such
           ---------------
waivers and releases of liens or claims upon any Service Equipment as Mortgagee
may reasonably require, and shall keep and maintain the Mortgaged Property free
from the claim of all persons supplying labor or materials in connection with
the construction or repair of any building on the Premises, to the extent
applicable. If any mechanics lien is filed against the Mortgaged Property,
Mortgagor shall cause, at its sole cost and expense, the same to be released,
discharged or bonded of record within sixty (60) days after the date of filing
thereof.

     1.12. Right to Cure. Mortgagor agrees that, at Mortgagee's option, in case
           -------------
Mortgagor shall fail to pay the same when due and such failure continues beyond
notice and cure periods, to the extent provided by applicable law, Mortgagee may
pay any expense or item (including, but not limited to, taxes, rates,
assessments, other charges, insurance premiums, maintenance and repair expenses,
and expenses incurred in protection of the lien of this Mortgage) which
Mortgagor herein agrees to pay; and may perform any acts or covenants which
Mortgagor herein agrees to perform and shall fail to perform, and may add the
same, and the expense thereof, including, but not limited to, reasonable counsel
fees and other costs, charges and disbursements incurred by Mortgagee in
connection therewith, to the Indebtedness or may, at its option, deduct the same
from any part of money thereafter advanced and Mortgagor agrees to repay on
demand, the same to Mortgagee, together with interest thereon at the rate set
forth in the Note, from the date on which such payment or expense is made or
incurred by Mortgagee, and the same shall be a lien upon the Mortgaged Property
prior to any right, title, interest, lien or claim thereto or thereon attaching
or accruing subsequent to the lien of this Mortgage and shall be deemed to be
secured by this Mortgage. Notwithstanding the foregoing, Mortgagor may in good
faith by appropriate

                                       9

<PAGE>

proceedings and upon notice to Mortgagee, contest the validity, applicability or
amount of any asserted tax or assessment, so long as (i) such contest is
diligently pursued, (ii) Mortgagee determines in its sole opinion, that such
contest suspends the obligation to pay the tax and that nonpayment of such tax
or assessment will not result in the sale, loss, forfeiture or diminution of the
Mortgaged Property or any part thereof or any interest of Mortgagee therein, and
(iii) prior to the earlier of the commencement of such contest or the
delinquency date of the asserted tax or assessment, Mortgagor deposits with
Mortgagee an amount determined by Mortgagee to be adequate to cover the payment
of such tax or assessment and a reasonable additional sum to cover possible
interest, costs and penalties; provided, however, that Mortgagor shall promptly
cause to be paid any amount adjudged by a court of competent jurisdiction to be
due, with all interest, costs and penalties thereon, promptly after such
judgment becomes final; and provided further that in any event each such contest
shall be concluded, the taxes, assessments, interests, costs and penalties shall
be paid prior to the date any writ or order is issued under which the Mortgaged
Property may be sold, lost or forfeited.

     1.13. Reliance on Documents. Mortgagor covenants that Mortgagee, in making
           ---------------------
any payment herein authorized in the place and stead of Mortgagor which (i)
relates to taxes, assessments, or any other Impositions and any other
governmental or municipal charges, fines, impositions or liens asserted against
the Mortgaged Property, may do so according to any bill, statement or estimate
procured from the appropriate public office without inquiry into the accuracy
thereof or into the validity of any tax, assessment, sale, forfeiture, tax lien
or title or claim thereof; or (ii) relates to insurance premiums, may do so
according to any notice, bill, statement or estimate procured from the
appropriate insurer without inquiry into the accuracy or validity thereof; or
(iii) relates to any apparent or threatened adverse title, lien, statement of
lien, encumbrance, claim or charge, shall be the sole judge of the legality or
validity of same; or (iv) relates to the expense of repairs or replacement of
any buildings, improvements, Service Equipment or any other Mortgaged Property,
shall be the sole judge of the state of repairs and the necessity for incurring
the expense of any such repairs or replacement; or (v) otherwise relates to any
other purpose not specifically enumerated in this Article, may do so whenever,
in its reasonable judgment and discretion, such payment shall seem necessary or
desirable to protect the full security intended to be created by this Mortgage,
and provided further that, in connection with any such payment, Mortgagee, at
Mortgagee's option, may and is hereby authorized to obtain a continuation report
of title prepared by a title insurance company, the costs and expenses of which
with report shall be payable by Mortgagee.

     1.14. Indemnification. Mortgagor expressly agrees that any and all expenses
           ---------------
incurred in connection with the Indebtedness shall be paid by Mortgagor,
including, but not limited to, the cost of title insurance premiums and charges,
recording fees, survey costs, brokerage fees, fees charged for the placement and
servicing of the Indebtedness, appraisal fees, construction inspection fees,
fees charged by consulting architects and engineers, costs of document
preparation, and Mortgagee's reasonable attorneys' fees and out-of-pocket
expenses and disbursements. Mortgagor agrees to pay all such fees and indemnify
and save Mortgagee harmless against the claims of any persons claiming any fees,
reimbursements, commissions and/or costs arising out of the Indebtedness.
Mortgagor shall indemnify, defend and hold Mortgagee and Mortgagee's directors,
officers, employees and agents harmless from and against and reimburse them on
demand for all claims, demands, liabilities, losses, damages, judgments,
penalties, costs and expenses (including reasonable attorneys' fees and amounts
paid in settlement) which may be imposed upon, asserted against, or incurred or
paid by any of them (a) by reason of, on account of or in connection with any
act or occurrence relating to the Mortgaged Property or any bodily injury,
death, other personal injury or property damage occurring in, upon or in the
vicinity of the Premises through any cause whatsoever, (b) as a result of the
failure of Mortgagor to perform any of its obligations under any of the
Financing Agreements, or (c) on account of any act performed or omitted to be
performed hereunder or on account of any transaction arising out of or in any
way connected with the Mortgaged

                                       10

<PAGE>

Property, this Mortgage any Financing Agreement or the Indebtedness, including,
without limitation, all claims of any brokers arising out of or in connection
with the Note and the transactions contemplated hereunder, except as a result of
the gross negligence and willful misconduct of Mortgagee. Mortgagor shall
indemnify and repay Mortgagee promptly upon demand for any expenditures or
amounts advanced by Mortgagee at any time under the Financing Agreements, except
that principal and interest under the Note shall be paid in accordance with the
terms set forth in the Note.

     1.15. Maintenance and Repair. Mortgagor shall maintain the Mortgaged
           ----------------------
Property in good condition, working order and repair, and shall not commit or
suffer any waste thereon. Mortgagor shall promptly repair, restore, replace or
rebuild any part of the Mortgaged Property which may be damaged or destroyed by
any casualty whatsoever or which may be affected by any proceeding of the
character referred to in the Article hereof entitled "Eminent Domain."

     1.16. Alteration and Demolition. Mortgagor agrees that no building or other
           -------------------------
property now or hereafter covered by the lien of this Mortgage shall be removed,
demolished, or structurally altered without the prior written consent of
Mortgagee, which consent shall not be unreasonably withheld, except that
Mortgagor may remove or dispose of, free from the lien of this Mortgage, any
Service Equipment as from time to time may become worn out or obsolete, provided
that prior to such removal, any such Service Equipment shall be replaced with
other equipment of value and utility at least equal to that of the replaced
Service Equipment and free from any title retention or security agreement or
other encumbrance. By such removal and replacement, Mortgagor shall be deemed to
have automatically subjected such other equipment to the lien of this Mortgage
and the Article hereof entitled "Security Agreement". Mortgagor shall
immediately notify Mortgagee of any such replacement and shall further execute
such mortgage, security agreement, or other documents as Mortgagee may require
with respect thereto.

     1.17. Restrictions on Sale and Use of Premises and Collateral. Mortgagor
           -------------------------------------------------------
will not sell, lease, pledge, mortgage, grant a deed or trust, otherwise
encumber, suffer change in title or ownership of, or otherwise transfer, or vest
title in anyone other than Mortgagor to, all or any part of the Mortgaged
Property or any other collateral granted to the Mortgagee as security for the
Loan or any other indebtedness or obligation owed by the Mortgagor to the
Mortgagee, while any part of the indebtedness secured hereby remains unpaid,
except with Mortgagee's prior written consent. Further, unless required by
applicable law or unless Mortgagee has otherwise agreed in writing, Mortgagor
shall not allow changes in the nature of the uses and occupancy for which the
Premises were intended on the date of this Mortgage.

     1.18. Independence of Premises. Mortgagor shall not by act or omission
           ------------------------
permit any building or other improvements on the Premises not subject to the
lien of this Mortgage to rely on the Premises or any part thereof or any
interest therein to fulfill any municipal or governmental requirement for the
existence of such premises or such building or improvement; and no building or
other improvement on the Premises shall rely on any premises not subject to the
lien of this Mortgage or any interest therein to fulfill any governmental or
municipal requirement. Mortgagor shall not by act or omission impair the
integrity of the Premises as a single subdivided zoning lot separate and apart
from all other premises.

     1.19. Compliance with Local, State and Federal Regulations.
           ----------------------------------------------------

          (a) Mortgagor has or will to the extent appropriate and obtainable,
procured any and all necessary certificates, licenses, authorizations,
registrations, permits, environmental and zoning

                                       11

<PAGE>

resolutions and/or approvals necessary for the operation of all present and
contemplated improvements and businesses at the Mortgaged Property.

          (b) Respecting the Mortgaged Property and the use and operation
thereof, Mortgagor and any guarantor are and shall at all times remain in
compliance with all federal, state and local laws and ordinances with respect to
the conduct of Mortgagor's business or business operations, and Mortgagor and
any guarantor of the Indebtedness are not and shall not be at any time in
violation of any zoning, environmental protection (including, without
limitation, air pollution, water pollution, and inland wetland proscriptions),
health, occupation, safety or other law, regulation or order.

     1.20. Covenants Regarding Construction. Mortgagor hereby covenants and
           --------------------------------
agrees with Mortgagee that Mortgagor shall:

          (a) Promptly proceed with the construction and erection of the
improvements on the Premises in accordance with the plans and specifications to
be approved by Mortgagee (the "Approved Plans");

          (b) Complete all construction and erection of said improvements
substantially in conformity with the Approved Plans and change orders approved
by Mortgagee or otherwise permitted hereunder and any and all applicable present
and future requirements of municipal, state or federal authorities having
jurisdiction thereover but in no event later than the date that is twelve (12)
months from the date hereof, and promptly notify Mortgagee of any notice,
communication or order from any such authorities;

          (c) Apply each advance received by Mortgagor under the Financing
Agreements solely for the specific purposes approved by Mortgagee in connection
with Mortgagor's specific request for said advance in accordance with the
Approved Plans and for no other purpose;

          (d) In the event of termination, cancellation or suspension of any
governmental agreement, approval, certificate, license or permit which is
necessary for the commencement, continuation or completion of construction,
Mortgagor shall restore or remedy such termination, cancellation or suspension
within fourteen (14) days thereafter, provided that if such cannot be restored
or remedied within fourteen (14) days; then Mortgagor shall commence all actions
required to restore or remedy such matter within such fourteen (14) day period
and diligently complete such restoration or remedy thereafter. Mortgagor shall
give notice to Mortgagee of any such termination, suspension or cancellation
within three (3) business days after receipt thereof. If Mortgagor is threatened
with any such termination, suspension or cancellation, Mortgagor shall promptly
notify Mortgagee thereof and shall use every reasonable means to prevent such
termination, suspension or cancellation form occurring. Mortgagor hereby further
agrees to promptly forward the copy of any notice or communication from any
governmental authority pertaining to the aforesaid construction to Mortgagee;

          (e) Furnish requests for advances in accordance with the terms and
conditions of that certain Construction Loan Agreement, dated as of the date
hereof, executed by Mortgagor, as borrower, in favor of Mortgagee, as lender,
and support such requests with the documentation required pursuant to the
Construction Loan Agreement;

          (f) Not perform any further work on said improvements after Mortgagee
has ordered stoppage of construction without the prior written consent of
Mortgagee unless and until the condition that led to said stop order has been
fully corrected to Mortgagee's sole satisfaction. Mortgagee shall have

                                       12

<PAGE>

the right to order such stoppage and to demand that a condition be corrected
when a material deviation from the Approved Plans appears, or defective or
unworkmanlike labor or materials are being used in the construction of said
improvements, or upon the occurrence of any breach of or default hereunder;

          (g) Secure each and every permit, license or approval required to be
obtained in connection with the contemplated construction of the improvements
upon the Premises in accordance with the Approved Plans;

          (h) Permit the Mortgagee to conduct regular progress and quality
inspections of the Premises in order to analyze and substantiate each request
for an advance under the Note. All such inspections shall be made, at the
Mortgagor's sole cost and expense, by an inspector approved by the Mortgagee, at
its sole discretion.

                                      II.
                               SECURITY AGREEMENT

     2.1. Creation of Security Interest. This Mortgage shall constitute a
          -----------------------------
Security Agreement within the meaning of the Connecticut Uniform Commercial Code
(the "Code") with respect to all sums on deposit with Mortgagee hereunder
("Deposits") and with respect to any property included in the definition herein
of the words "Mortgaged Property," which interests or property may not be deemed
to form a part of the real estate described in Schedule "A" or may not
                                               ------------
constitute a "fixture" (within the meaning of the Code), and all Service
Equipment and all replacements of and substitutions for such property and
interests, additions to such property, and the proceeds thereof (said property,
interests, replacements, substitutions, the proceeds thereof being sometimes
herein collectively referred to as the "Collateral"). A security interest in and
to the Collateral is therefore hereby granted to Mortgagee. The Deposits and all
of Mortgagor's right, title and interest therein are hereby assigned to
Mortgagee. The foregoing rights and Collateral are hereby granted or assigned to
Mortgagee to secure payment of the entire indebtedness secured hereunder and to
secure performance by Mortgagor of the terms, covenants and provisions hereof.
Accordingly, in addition to any other rights and remedies availed to Mortgagee
hereunder, Mortgagee shall have all the rights of a "secured party" under the
Code, as amended from time to time.

     2.2. Warranties, Representations and Covenants of Mortgagor. Mortgagor
          ------------------------------------------------------
hereby warrants, represents and covenants as follows:

          (a) The Collateral, except for the Deposits, shall be kept on or at
the Premises, and Mortgagor shall not remove the Collateral from the Premises
without the prior consent of Mortgagee, except as otherwise provided herein.
Mortgagor shall execute, deliver, file and refile any financing statements,
continuation statements, or other security agreements which Mortgagee may
require from time to time to confirm the continuing lien of this Mortgage with
respect to such property.

          (b) The Mortgagor shall not change its name, identity, ownership or
its management while the Indebtedness remains outstanding without the prior
written consent of the Mortgagee. In the event of any change in name,
management, ownership or identity of Mortgagor which is authorized hereunder,
Mortgagor shall promptly, after written request, execute such UCC forms or
statements as are deemed by Mortgagee or required pursuant to the Code to be
necessary to maintain the continuing priority of Mortgagee's lien upon the
Collateral, including future replacements thereof, and shall pay all expenses in
connection with the filing and recording thereof.

                                       13

<PAGE>

          (c) To the extent permitted by law, Mortgagor hereby authorizes
Mortgagee to sign and file financing or continuation statements at any time with
respect to any of the Collateral, without such financing statements being
executed by or on behalf of Mortgagor. Mortgagor also irrevocably appoints
Mortgagee as its attorney-in-fact, coupled with an interest, to file with the
appropriate public office on its behalf any financing or other statements signed
only by Mortgagee, as secured party, in connection with the Collateral now or
hereafter covered by this Mortgage. Notwithstanding the foregoing, Mortgagor
shall execute or cause to be executed, such additional or alternate financing or
continuation statements required by Mortgagee and shall reimburse Mortgagee for
all costs and expenses of any kind incurred in connection therewith, including,
without limitation, Mortgagee's attorney's fees.

     2.3. Financing Statements. A carbon, photographic or other reproduction of
          --------------------
this Mortgage or any financing statement relating to this Mortgage shall be
sufficient as a financing statement within the meaning of the Code. This
Mortgage is effective and shall be effective as a financing statement filed as a
fixture filing with respect to the Service Equipment, Collateral and any and all
goods which are or are to become fixtures included within the Mortgaged Property
as shall be filed for record in the applicable land records. The mailing address
of Mortgagee and the address of Mortgagor from which information concerning the
security interest may be obtained are set forth on the cover sheet hereof and in
the section hereof entitled "Notices."

                                      III.
                             ENVIRONMENTAL MATTERS

     3.1. Representations and Indemnity. Mortgagor represents, warrants and
          -----------------------------
covenants that:

          (a) Except as set forth in that certain Environmental Site Assessment
for Five Vacant Parcels in the Medway Business Park, Wallingford, Connecticut,
dated November, 2000, prepared by GZA GeoEnvironmental, Inc. (the "Phase I"),
and except as necessary for Guarantor to operate the Project for its intended
purpose, no Hazardous Substances (as hereinafter defined), including without
limitation asbestos and the group of organic compounds known as polychlorinated
biphenyls, have been, are or shall be generated, treated, stored or disposed of,
or otherwise deposited in or located on the Premises in violation of applicable
"Environmental Laws" (as that term is defined in that certain Environmental
Indemnity Agreement executed by Mortgagor and Guarantor in favor of Mortgagee as
of the date hereof), including without limitation the surface and subsurface
waters of the Premises;

          (b) Except as set forth in the Phase I, no activity is (or, so long as
any portion of the Loan remains unpaid, shall be) undertaken on the Premises
which would cause (1) the Premises to become a hazardous waste treatment,
storage or disposal facility within the meaning of the Resource Conservation and
Recovery Act of 1976, 42 U.S.C. ss.6901 et seq., as the same may be amended from
time to time ("RCRA"), or any similar state laws, regulations or local
ordinances, or (2) a release or threatened release of Hazardous Substances (as
herein defined) on the Premises in violation of Environmental Laws or that
triggers a legal obligation to perform Remedial Work pursuant to Environmental
Laws;

          (c) Neither the Mortgagor, Guarantor, nor any tenant or other occupant
of the Premises, nor any other party over whom Mortgagor or Guarantor has
control, shall hereafter cause or suffer to occur, any discharge, spillage,
uncontrolled loss, or other release of oil, petroleum, chemical liquids or
solid, liquid or gaseous products or Hazardous Substances of any kind, at, upon,
under, within, through or emanating from the Premises in violation of applicable
Environmental Laws or that triggers a legal obligation to perform Remedial Work
pursuant to Environmental Laws. Except as set forth in the Phase I, neither
Mortgagor, Guarantor, nor any tenant or other occupant of the Premises, nor any
other

                                       14

<PAGE>

party over whom Mortgagor or Guarantor has control, has been, is and shall be
involved in operations at the Premises, nor shall Mortgagor, Guarantor, nor any
tenant or other occupant of the Premises deposit any substances or create any
conditions in or on the Premises, which could support a claim or cause of action
or lead to the imposition on the Mortgagor or any other owner or operator of the
Premises of liability or the creation of a lien on the Premises under any of the
Environmental Laws;

          (d) Mortgagor shall comply strictly and in all respects with the
requirements of the applicable Environmental Laws and shall notify Mortgagee
promptly after Mortgagor becomes aware of any spill or contamination upon the
Premises in violation of Environmental Laws or that triggers a legal obligation
to perform Remedial Work pursuant to Environmental Laws, and shall promptly
forward to Mortgagee copies of all orders, notices, permits, applications or
other communications and reports in connection with any such spill or any other
matters relating to the Environmental Laws as they may affect the Premises;

          (e) So long as any portion of the Loan remains unpaid and Mortgagee
has reasonable belief that conditions exist that would trigger the
indemnification provisions of this Article III, Mortgagor agrees that Mortgagee
may perform such additional environmental due diligence, from time to time, as
Mortgagee deems necessary in its judgment at Mortgagor's expense. Mortgagor
agrees and recognizes that Mortgagee, at its option, may require that additional
collateral or prepayments of principal be made in the event that an unacceptable
environmental condition shall exist with respect to the Premises, in Mortgagee's
sole discretion. The failure of Mortgagor to satisfy the requirements of
Mortgagee pursuant to this provision with ninety (90) days after written notice
thereof shall be deemed an Event of Default hereunder;

          (f) As a further inducement to Mortgagee to enter into the Loan,
Mortgagor and Guarantor covenants and agrees at all times to indemnify, hold
harmless and defend Mortgagee, and its directors, officers, employees, agents,
and any successors or assignees of Lender's interests in the Loan forever,
whether as holder of the Mortgage, as secured party in possession, or as
successor in interest to Mortgagor as owner of the Premises, by virtue of
foreclosure or acceptance of a deed in lieu of foreclosure or otherwise
(collectively, the "Indemnified Parties") from and against any and all
                    -------------------
liabilities, losses, damages, costs, expenses, penalties, fines, causes of
action, suits, claims, demands or judgments that are not caused by the negligent

Parties, their agents, employees or tenants, including, without limitation,
reasonable attorneys' fees and expenses, suffered or incurred in connection
with: (i) any claim under Environmental Laws including, without limitation,
liens or claims of any federal, state or municipal government or
quasi-governmental agency or any third person, whether arising under the
Environmental Laws or any other federal, state or municipal law or regulation;
(ii) any spill or contamination affecting the Premises, including, without
limitation, any Hazardous Substances located on, under, emanating from or
relating to the Premises from and on and after the date hereof or any portion

a result of any such spill or contamination; and (iii) the direct or indirect

                                       15

<PAGE>

Laws, Mortgagee may, at its election, but without the obligation so to do (or to
continue to do so if it commences to do so), give such notices and/or cause such
work to be performed at the Premises and/or take any and all other actions as
Mortgagee shall deem necessary or advisable in order to remedy said spill or
cure said failure of compliance, and any amounts paid as a result thereof,
together with interest thereon at the highest rate provided for by the Note from
the date of payment by Mortgagee and until paid shall be added to and become a
part of the indebtedness secured by this Mortgage.

          (h) As used in this Agreement, the term "Hazardous Substances" shall
mean "waste materials," "solid waste", and "hazardous substances" as such terms
are defined in Environmental Laws.

     3.2. Remedial Work.
          -------------

          (a) If any investigation, site monitoring, containment, cleanup,
removal, restoration or other remedial work of any kind or nature (collectively,
the "Remedial Work") is required under any applicable Environmental Law because
of or in connection with the current or future presence, suspected presence,
release or suspected release of a Hazardous Substance into the air, soil, ground
water, surface water, or soil vapor on, under or about the Premises or any
portion thereof, Mortgagor shall promptly commence and diligently prosecute to
completion all the Remedial Work. In all events, the Remedial Work shall be
commenced within ninety (90) days after any demand therefor by Mortgagee or such
shorter period as may be required under any applicable Environmental Law.

          (b) All the Remedial Work shall be performed by contractors, and under
the supervision of a consulting engineer, each approved in advance by Mortgagee,
which approval shall not be unreasonably withheld. All costs and expenses of the
Remedial Work and Mortgagee's monitoring or review of the Remedial Work
(including reasonable attorneys' fees) shall be paid by Mortgagor. If Mortgagor
does not timely commence and diligently prosecute to completion the Remedial
Work, Mortgagee may (but shall not be obligated to) cause the Remedial Work to
be performed. Mortgagor agrees to bear and shall pay or reimburse Mortgagee on
demand for all advances and expenses (including reasonable attorneys' fees)
relating to or incurred by Mortgagee in connection with monitoring, reviewing or
performing any Remedial Work.

          (c) Except with Mortgagee's prior consent, Mortgagor shall not
commence any Remedial Work or enter into any settlement agreement, consent
decree or other compromise relating to any Hazardous Substances or Environmental
Laws which might, in Mortgagee's judgment, impair the value of Mortgagee's
security hereunder. Mortgagee's prior consent shall not be required, however, if
the presence or threatened presence of Hazardous Substances on, under or about
the Premises poses an immediate threat to the health, safety or welfare of any
person or is of such a nature that an immediate remedial response is necessary,
and it is not possible to obtain Mortgagee's prior consent. In such event
Mortgagor shall notify Mortgagee as soon as practicable of any action taken.

                                       16

<PAGE>

     3.3. Inspection. Mortgagor shall promptly upon the request of any of the
          ----------
Indemnified Parties at any time and from time to time: (i) execute such further
instruments and deliver such further documents as are reasonably necessary to
confirm and enforce the representations and indemnification provided herein;
(ii) so long as any portion of the Loan remains unpaid and Mortgagee has
reasonable belief that conditions exist that would trigger the indemnification
provision of this Article III, Mortgagor, at its sole cost and expense, shall
provide Mortgagee with an environmental site assessment or environmental audit
report, or an update of such an assessment or report, all in scope, form and
content reasonably satisfactory to Mortgagee; and (iii) so long as any portion
of the Loan remains unpaid and Mortgagee has reasonable belief that conditions
exist that would trigger the indemnification provision of this Article III allow
access to the Lender or its assignee to enter and perform any environmental
studies or site assessments.

                                       IV.

to completion, all steps necessary to remedy such failure, for an aggregate
period not to exceed sixty (60) days after written notice by Mortgagee to
Mortgagor of such failure; or (e) the failure of the Mortgagor to pay the

such guarantor, or the appointment of a receiver for any part of any of their
respective properties and the failure to dismiss the same within ninety (90)
days or the admission in writing by the Mortgagor or any guarantor of the
inability to pay debts are they become due; or (k) any sale, conveyance, lease,
transfer or encumbrance of any right, title or interest in the Mortgaged

<PAGE>

charter or bylaws which have a material adverse affect on the Mortgaged
Property; or (m) any merger or consolidation of Mortgagor with another entity or

is threatened by reason of a material adverse change in the financial condition
or credit standing of Mortgagor or any guarantor or other obligor for the
payment of the Note, including, without limitation, the commencement of any
litigation or proceeding and, within ten (10) days after Mortgagee gives notice
of such determination to Mortgagor, Mortgagor or any such guarantor or other
obligor fails to either provide Mortgagee either with additional collateral, in
form and substance satisfactory to Mortgagee, in Mortgagee's sole discretion, to
secure the Indebtedness or repay a sufficient portion of the Indebtedness in
order to alleviate such concern, as determined by Mortgagee; or (q) Mortgagor
fails to proceed diligently with the construction of contemplated improvements
set forth in the Approved Plans, and said failure is not remedied within fifteen
(15) days after written notice by Mortgagee to Mortgagor, or if such failure is
of such a nature that it cannot with due diligence be completely remedied within
such fifteen (15) day period and Mortgagor shall not commence to cure within
said period of fifteen (15) days, or shall not thereafter diligently prosecute
to completion, all steps necessary to remedy such failure, for an aggregate
period not to exceed sixty (60) days after written notice by Mortgagee to
Mortgagor of such failure; or (r) Mortgagor uses the loan proceeds from the Loan

exceed sixty (60) days after written notice by Mortgagee to Mortgagor of such
failure; or (t) if Mortgagor shall cease to exist.

     4.2. Remedies Generally. If an Event of Default shall occur, in addition to
          ------------------
all other rights of Mortgagee as provided herein or by law, Mortgagee may, at
its sole election, also exercise any or all of the following rights, remedies
and recourses:

          (a) Acceleration: Declare the principal balance on the Note, the
              ------------
accrued interest and any other accrued but unpaid portion of the Indebtedness to
be immediately due and payable, without notice, presentment, protest, demand or
action of any nature whatsoever (each of which hereby is expressly waived by
Mortgagor), whereupon the same shall become immediately due and payable, time
being of the essence in this Mortgage.

          (b) Termination of License and/or Entry of Mortgaged Property: Demand
              ---------------------------------------------------------
that Mortgagor shall forthwith surrender to Mortgagee actual possession of the
Mortgaged Property, and/or

                                       18

<PAGE>

terminate the license granted Mortgagor to receive the Rents and, to the extent
permitted by law, enter and take possession of all of the Mortgaged Property
without the appointment of a receiver, or an application therefor, and exclude
Mortgagor and its agents and employees wholly therefrom, and have joint access
with Mortgagor to the books, papers and accounts of Mortgagor.

          If Mortgagor shall for any reason fail to surrender or deliver the
Mortgaged Property or any part thereof after such demand by Mortgagee, Mortgagee
may obtain a judgment or decree conferring upon Mortgagee the right to immediate
possession or requiring Mortgagor to deliver immediate possession of the
Mortgaged Property to Mortgagee. Mortgagor will pay to Mortgagee, upon demand,
all expenses of obtaining such judgment or decree, including compensation to
Mortgagee, its attorneys and agents, and all such expenses and compensation
shall, until paid, become part of the Indebtedness and shall be secured by this
Mortgage.

          Upon every such entering upon (1) undertake all necessary and proper
maintenance, repairs, renewals, replacements, additions, betterments and
improvements thereto and thereon and purchase or otherwise acquire additional
fixtures, personalty and other property, (2) insure or keep the Mortgaged
Property insured, (3) manage and operate the Mortgaged Property and exercise all
the rights and powers of Mortgagor to the same extent as Mortgagor could in its
own name or otherwise act with respect to the same, and (4) enter into any and
all agreements with respect to the exercise by others of any of the powers
herein granted to Mortgagee, all as Mortgagee from time to time may determine to
be in its best interest. Whether or not Mortgagee has obtained possession of the
Mortgaged Property, upon the termination of Mortgagor's license to receive the
Rents, Mortgagee may collect, sue for and receive all the Rents and other
issues, profits and revenues from the Mortgaged Property, including those past
due as well as those accruing thereafter. Anything in this Mortgage to the
contrary notwithstanding, subject to the provisions of any attornment and
non-disturbance agreement entered into by and between Mortgagee and any lessee,
Mortgagee shall not be obligated to discharge or perform the duties of the
landlord to any tenant or lessee or incur any liability as the result of any
exercise by Mortgagee of its rights under this Mortgage, and Mortgagee shall be
liable to account only for the Rents actually received by Mortgagee.

          Whether or not Mortgagee takes possession of the Mortgaged Property,
Mortgagee may, but shall not be obligated to, make, modify, enforce, cancel or
accept surrender of any Lease, remove and evict any lessee, increase or decrease
Rents under any Lease, appear in and defend any action or proceeding purporting
to affect the Mortgaged Property, and perform and discharge each and every
obligation, covenant and agreement of Mortgagor contained in any Lease. Neither
the entering upon and taking possession of the Mortgaged Property, nor the
collection of any Rents and the application thereof as aforesaid, shall cure or
waive any Event of Default theretofore or thereafter occurring, or affect any
notice of an Event of Default hereunder or invalidate any act done pursuant to
any such notice. Mortgagee shall not be liable to Mortgagor, anyone claiming
under or through Mortgagor, or anyone having an interest in the Mortgaged
Property by reason of anything done or left undone by Mortgagee hereunder.
Nothing contained in this Section shall require Mortgagee to incur any expense
or do any act. If the Rents are not sufficient to meet the costs of taking
control of and managing the Mortgaged Property and/or collecting the Rents, any
funds expended by Mortgagee for such purposes shall become Indebtedness of
Mortgagor to Mortgagee secured by this Mortgage. Such amounts, together with
interest at the default rate under the Note and attorneys' fees, if applicable,
shall be immediately due and payable. Notwithstanding Mortgagee's continuance in
possession or receipt and application of Rents, Mortgagee shall be entitled to
exercise every right provided for in this Mortgage or by law upon or after the
occurrence of an Event of Default. Any of the actions referred to in this
Section may be taken by

                                       19

<PAGE>

Mortgagee at such time as Mortgagee is so entitled, to the extent permitted by
law, without regard to the adequacy of any security for the Indebtedness hereby
secured.

          (c) Proofs of Claim. In the case of any receivership, insolvency,
              ---------------
bankruptcy, reorganization, arrangement, adjustment, composition or other
proceedings affecting Mortgagor, its creditors or its property, Mortgagee, to
the extent permitted by law, shall be entitled to file such proofs of claim and
other documents as may be necessary or advisable in order to have the claims of
Mortgagee allowed in such proceedings for the entire amount of the Indebtedness
at the date of the institution of such proceedings and for any additional amount
of the Indebtedness after such date.

     4.3. No Waiver, etc. Any failure by Mortgagee to insist upon the strict
          --------------
performance by Mortgagor or any guarantor of any of the terms and provisions
hereof shall not be deemed to be a waiver of any of the terms and provisions
hereof, and Mortgagee, notwithstanding any such failure, shall have the right
thereafter to insist upon the strict performance by Mortgagor or any guarantor,
of any and all of the terms and provisions of this Mortgage, the Note to be
performed by Mortgagor or any guarantor; and neither Mortgagor, nor any
guarantor nor any other person now or hereafter obligated for the payment of the
whole or any part of the Indebtedness shall be relieved of such obligation by
reason of the failure of Mortgagee to comply with any request of Mortgagor, any
guarantor or of any other person so obligated to take action to foreclose this
Mortgage or otherwise enforce any of the provisions of this Mortgage or of any
obligation secured by this Mortgage, or by reason of the release, regardless of
consideration, of the whole or any part of the security held for the
Indebtedness or of any obligor for such Indebtedness, or by reason of any
agreement or stipulation between any subsequent owner or owners of the Mortgaged
Property and Mortgagee extending the time of payment or modifying the terms of
the Note or this Mortgage without first having obtained the consent of Mortgagor
or such other person, and in the latter event, Mortgagor and all such other
persons shall continue to be liable to make such payments according to the terms
of any such agreement of extension or modification unless expressly released and
discharged in writing by Mortgagee; and, regardless of consideration, and
without the necessity for any notice to or consent by the holder of any
subordinate lien on the Premises, Mortgagee may release the obligation of anyone
at any time liable for any of the Indebtedness or any part of the security held
for said Indebtedness and may extend the time of payment or otherwise modify the
terms of the Note and/or this Mortgage without, as to the security or the
remainder thereof, in any way impairing or affecting the lien of this Mortgage,
or the priority of such lien, as security for the payment of said Indebtedness
as it may be so extended or modified over any subordinate lien; and the holder
of any subordinate lien shall have no right to terminate any Lease whether or
not such Lease shall be subordinate to this Mortgage; and Mortgagee may resort
for the payment of the Indebtedness to any other security therefor, held by
Mortgagee in such order and manner as Mortgagee may elect.

     4.4. Marshalling. Mortgagee shall not be compelled to release, or be
          -----------
prevented from foreclosing or enforcing this Mortgage upon all or any part of
the Mortgaged Property, unless the entire Indebtedness and all items hereby
secured shall be paid in lawful money as aforesaid; and shall not be required to
accept any part or parts of the Mortgaged Property, as distinguished from the
entire whole thereof, as payment of or upon the Indebtedness to the extent of
the value of such part or parts; and shall not be compelled to accept or allow
any apportionment of the Indebtedness to or among any separate parts of the
Mortgaged Property. In case of a foreclosure sale, the Mortgaged Property may be
sold in one parcel and as an entirety or in such parcels, manner or order as
Mortgagee in its sole discretion may elect.

                                       20

<PAGE>

     4.5. Interest After Judgment. Should Mortgagee herein obtain a judgment
          -----------------------
against Mortgagor, interest shall accrue on said judgment at the default
interest rate set forth in the Note or as provided by statute, whichever rate
shall be greater at that time.

     4.6. Rights and Remedies Cumulative. To the extent permitted by law, the
          ------------------------------
rights and remedies provided for in this Mortgage, or which Mortgagee may have
otherwise, at law or in equity (including, but not limited to, the right to
damages by reason of the failure of Mortgagor to keep, observe and perform any
of the covenants or agreements contained in this Mortgage), shall be distinct,
separate and cumulative, and shall not be deemed to be inconsistent with each
other, and none of them, whether or not exercised by Mortgagee, shall be deemed
to be in exclusion of any other, and any two or more of all such rights and
remedies may be exercised at the same time. Further, Mortgagee may resort for
the payment of the Indebtedness to its several securities therefor in such order
or manner as it may think fit. If Mortgagor has given Mortgagee one or more
mortgages other than this Mortgage with respect to the Mortgaged Property or any
portion thereof, then all such mortgages, and all rights and remedies provided
for in all such mortgages shall remain distinct and separate and none of them
shall merge or be merged with this Mortgage, or any other mortgages.

     4.7. Foreclosure Expenses. If this Mortgage shall be foreclosed, there
          --------------------
shall be included in the computation of the Indebtedness the amount or the fee
for the services of the attorneys retained by Mortgagee in the foreclosure
action or proceeding, as well as any and all disbursements, costs and other
expenses incurred directly or indirectly by Mortgagee in connection with such
foreclosure action or proceeding, including, without limitation, appraisal fees.

     4.8. WAIVER OF JURY TRIAL. MORTGAGOR HEREBY WAIVES TRIAL BY JURY IN ANY
          --------------------
COURT IN ANY SUIT, ACTION OR PROCEEDING ON ANY MATTER ARISING IN CONNECTION WITH
OR IN ANY WAY RELATED TO THE FINANCING TRANSACTIONS OF WHICH THIS AGREEMENT IS A
PART AND/OR THE ENFORCEMENT OF ANY OF MORTGAGEE'S RIGHTS.

     4.9. PREJUDEMENT REMEDY WAIVER. MORTGAGOR HEREBY REPRESENTS, COVENANTS AND
          -------------------------
AGREES THAT THE PROCEEDS OF THE LOAN SHALL BE USED FOR GENERAL COMMERCIAL
PURPOSES AND THAT THE TRANSACTION OF WHICH THIS MORTGAGE IS A PART IS A
"COMMERCIAL TRANSACTION" AS DEFINED BY THE STATUTES OF THE STATE OF CONNECTICUT.
MORTGAGOR HEREBY WAIVES ALL RIGHTS TO NOTICE AND PRIOR COURT HEARING OR COURT
ORDER UNDER CONNECTICUT GENERAL STATUTES, SECTIONS 52-278a et seq., AS AMENDED,
OR UNDER ANY OTHER STATE OR FEDERAL LAW WITH RESPECT TO ANY AND ALL PREJUDGMENT
REMEDIES MORTGAGEE MAY EMPLOY TO ENFORCE ITS RIGHTS AND REMEDIES HEREUNDER. MORE
SPECIFICALLY, MORTGAGOR ACKNOWLEDGES THAT MORTGAGEE'S ATTORNEY MAY, PURSUANT TO
CONNECTICUT GENERAL STATUTES, SECTION 52-278f, ISSUE A WRIT FOR A PREJUDGMENT
REMEDY WITHOUT SECURING A COURT ORDER. MORTGAGOR ACKNOWLEDGES AND RESERVES ITS
RIGHT TO NOTICE AND A HEARING SUBSEQUENT TO THE ISSUANCE OF A WRIT FOR
PREJUDGMENT REMEDY BY MORTGAGEE'S ATTORNEY, AND MORTGAGEE ACKNOWLEDGES
MORTGAGOR'S RIGHT TO SAID HEARING SUBSEQUENT TO THE ISSUANCE OF SAID WRIT.
MORTGAGOR FURTHER HEREBY WAIVES ANY REQUIREMENT OR OBLIGATION OF MORTGAGEE TO
POST A BOND OR OTHER SECURITY IN CONNECTION WITH ANY PREJUDGMENT REMEDY

OBTAINED BY MORTGAGEE BASED ON ANY OFFSETS, CLAIMS, DEFENSES OR COUNTERCLAIMS OF
MORTGAGOR OR ANY OTHER OBLIGATED PARTY TO ANY ACTION BROUGHT BY MORTGAGEE.
MORTGAGOR ACKNOWLEDGES AND AGREES THAT ALL OF THE WAIVERS CONTAINED IN THIS
SECTION HAVE BEEN MADE KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND INTELLIGENTLY,
AND WITH THE ADVICE OF ITS COUNSEL.

                                       V.
