           We are pleased to advise you that Fleet National Bank, a Bank of
America company (the "Bank") holds available for the use of KSW, Inc., a
Delaware corporation (the "Company") a partially secured line of credit in the
amount of up to TWO MILLION AND 00/100 DOLLARS ($2,000,000.00) upon the
following terms and conditions:

           1. Facility. (a) A line of credit facility (the "Line") available for
short-term loans to the Company to support temporary working capital needs for
contracts in process (collectively, the "Loans"), provided that the aggregate
principal amount at any time outstanding shall not exceed the lesser of
$2,000,000.00 or the Collateral Value, as hereinafter defined, of the Investment
Securities held in the Collateral Account, each as hereinafter defined.

                     (b) Loans shall be extended upon the Company's prior
written notice to the Bank (duly executed by an authorized officer of the
Company), such notice to be in a form satisfactory to the Bank which may be
accomplished by facsimile transmission. Each such notice shall be accompanied by
detailed information satisfactory in all respects to the Bank regarding (if
applicable) the proposed uses by the Company for the proceeds of any Loan then
being requested. Such notice shall be given at least one Business Day prior to
any requested Prime Based Loan, as hereinafter defined, and at least three
Business Days prior to any requested LIBOR Based Loan, as hereinafter defined.
Such notice shall specify whether the requested Loan is a Loan under the secured
portion of this Line or the unsecured portion of same. The Bank shall not be
obligated to advance any Loans under this Line while the Company is in default
hereunder.

           2. Credit Period. The Line shall be available for the period
commencing with the date of the Company's acceptance and satisfaction of the
terms hereof and ending April 1, 2006 (the "Credit Period"). All Loans shall
mature on the last day of the Credit Period.

           3. Clean-up Requirement. Notwithstanding the foregoing, during a
single clean up period elected by the Company comprised of any thirty (30)
consecutive days during the Credit Period there shall be no unsecured Loans
outstanding under the Line.

           4. Interest and Fees. The Bank shall charge and shall be entitled to
receive the following (which amounts, together with any other amounts owing by
the Company to the Bank, may be charged to any demand deposit account maintained
by the Company with the Bank):

                     (a)(i) For that portion of the Loans fully secured by the
Collateral Requirement without reference to any Excess, as hereinafter
defined: Loans shall bear interest at a rate per annum to be elected by the
Company in accordance with the notice provisions in 1(b) above (at the Company's
option subject to availability) equal to the following: (y) the Prime Rate, as
defined in Schedule I attached hereto plus one-quarter of one (.25%) percent
(the "Variable Rate"), or (z) the LIBOR Rate, as defined in Schedule I attached
hereto, plus one and one-quarter (1.25%) percent per annum (the "Adjusted LIBOR
Rate")

                     (ii) For Loans, if any, expressly authorized by the terms
hereof, in excess of the Collateral Requirement, a rate of interest equal to
the Variable Rate plus three-quarters of one (.75%) percent ("Variable Rate
Unsecured", together with the Variable Rate Loans hereinafter, the "Prime Based
Loans") or (z) the Adjusted LIBOR Rate plus one and one-quarter (1.25%) percent
("Adjusted LIBOR Rate Unsecured", together with the Adjusted LIBOR Rate Loans,
the "LIBOR Based Loans").

                     (iii) In determining whether a Loan is fully secured,
reference shall be made to the last available account statement for the
Collateral
Account.

                     (b) LIBOR Based Loans shall be available for an interest
period of one month (the "Interest Period"). In no event shall any LIBOR Based
Loan Interest Period continue beyond the expiration of the Credit Period. Loans
shall be in minimum amounts of $100,000.00 with respect to Prime Based Loans and
$250,000.00 with respect to LIBOR Based Loans, or an integral multiple of
$100,000 in excess thereof. The outstanding principal balance of any Loan may be
converted from a Prime Based Loan to a LIBOR Based Loan, or from a LIBOR Based
Loan to a Prime Based Loan, provided that LIBOR Based Loans may only be
converted on the last day of the Interest Period applicable thereto and the
required prior notice must be provided in connection with the conversion of a
Prime Based Loan to a LIBOR Based Loan. Loans under the Line shall be evidenced
by a note in an amount equal to the maximum aggregate amount of Loans hereunder
(the "Note"). The Note shall contain standard provisions with regard to LIBOR
Based Loans for illegality, inability to determine rate, indemnification for
break funding, and increased cost or reduced return.

                     (c) Interest shall be computed on the basis of a 360-day
year for actual days elapsed and shall be payable monthly in arrears on the
first day of each month.

                     (d) If the entire amount of any required principal and/or
interest payment under the Loans is not paid in full within ten (10) days after
the same is due, the Company shall pay to the Bank a late fee equal to five (5%)
percent of the required payment. Upon default or after maturity or after
judgment has been rendered, or if any Event of Default has occurred and is

continuing, the Company's right to select pricing options shall cease and the
unpaid principal of all Loans (excluding any defaulted payment of principal
accruing interest in accordance with the preceding sentence) shall, at the
option of the Bank, bear interest at a rate which is four (4) percentage points
per annum greater than the otherwise applicable rate.

                     (e) Loans may be prepaid in whole or in part in a minimum
amount of $250,000.00 for LIBOR Based Loans and $100,000.00 for Prime Based
Loans, provided however, that any prepayment of any LIBOR Based Loan shall be
upon at least three (3) Business days prior written notice to the Bank (which
notice shall be irrevocable) and any such prepayment shall occur only on the
last day of the Interest Period for such LIBOR Based Loan and is subject to the
LIBOR Indemnification Provisions described on Schedule I attached hereto.

                     (f) An underwriting fee of $5,000.00 and all reasonable
fees and disbursements of the Bank's counsel in connection with the preparation
of any documentation, enforcement of the Bank's rights or otherwise in
connection with the Line, are due upon presentment of an invoice therefor.

           5. Guarantee. All obligations of the Company owing to the Bank under
the Line shall be unconditionally guaranteed by KSW Mechanical Services, Inc.
(the "Guarantor") pursuant to the Bank's standard form of guarantee of payment
(the "Guarantee").

           6. Collateral. (a) Loans under the Line shall be secured by a first
priority security interest in all investment securities (the "Investment
Securities") in an account owned by the Company and held with the Bank (the
"Collateral Account"). The Company will covenant to maintain a minimum amount of
Investment Securities in the Collateral Account equal to the "Collateral
Requirement", as hereinafter defined. The Collateral Requirement shall mean that
the (i) product of the applicable percentage advance rate indicated on the
attached Schedule II multiplied by the aggregate fair market value of each
corresponding type or category of Investment Securities indicated therein and
held in the Collateral Account plus the Applicable Excess, if any, shall be at

                             SCHEDULE I: DEFINITIONS
                             -----------------------

           1. Prime Rate: The term "Prime Rate" means the variable per annum
rate of interest so designated from time to time by Fleet National Bank as its
prime rate. The Prime Rate is a reference rate and does not necessarily
represent the lowest or best rate being charged to any customer. Changes in the
rate of interest resulting from changes in the Prime Rate shall take place
immediately without notice or demand of any kind.

           2. LIBOR Rate: The term "LIBOR" shall mean, as applicable to any
LIBOR Based Loan, the rate per annum as determined on the basis of the offered
rates for deposits in U.S. Dollars, for a period of time comparable to such
LIBOR Based Loan 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 first day of such
LIBOR Based Loan; 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 time comparable to
such LIBOR Based Loan 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 first day of such LIBOR Based Loan as
selected by Bank. 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 period of time comparable to such LIBOR Based Loan offered by major banks
in New York City at approximately 11:00 a.m. New York City time, on the day that
is two London Banking Days preceding the first day of such LIBOR Based Loan. In
the event that Bank is unable to obtain any such quotation as provided above, it
will be deemed that LIBOR pursuant to an LIBOR Based 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 Bank, 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 1 minus the Reserve
Percentage. "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.

           3. Banking Day: The term "Banking Day" shall mean, in respect of any
city, any day on which commercial banks are open for business in that city.

           4. LIBOR Indemnification Provisions: Company may prepay a LIBOR Based
Loan only upon at least three (3) Banking Days prior written notice to Bank
(which notice shall be irrevocable), and any such prepayment shall occur only on
the last day of the Interest Period for such LIBOR Based Loan. Company shall pay

<PAGE>
KSW, Inc.    -12-    March 28, 2005


to Bank, upon request of Bank, such amount or amounts as shall be sufficient (in
the reasonable opinion of Bank) to compensate it for any loss, cost, or expense
incurred as a result of: (i) any payment of a LIBOR Based Loan on a date other
than the last day of the Interest Period for such Loan; (ii) any failure by
Company to borrow a LIBOR Based Loan on the date specified by Company's written
notice; (iii) any failure by Company to pay a LIBOR Based Loan on the date for
payment specified in Company's written notice. Without limiting the foregoing,
Company shall pay to Bank a "yield maintenance fee", if any, in an amount
computed as follows: The current rate for United States Treasury securities
(bills on a discounted basis shall be converted to a bond equivalent) with a
maturity date closest to the term chosen pursuant to the LIBOR Rate Election as
to which the prepayment is made, shall be subtracted from the LIBOR in effect at
the time of prepayment. If the result is zero or a negative number, there shall
be no yield maintenance fee. If the result is a positive number, then the
resulting percentage shall be multiplied by the amount of the principal balance
being prepaid. The resulting amount shall be divided by 360 and multiplied by
the number of days remaining in the term chosen pursuant to the LIBOR Rate
Election as to which the prepayment is made. Said amount shall be reduced to
present value calculated by using the above referenced United States Treasury
securities rate and the number of days remaining in the term chosen pursuant to
the LIBOR Rate Election as to which prepayment is made. The resulting amount
shall be the yield maintenance fee due to Bank upon the prepayment of a LIBOR
Based Loan. Each reference in this paragraph to "LIBOR Rate Election" shall mean
the election by Company of the LIBOR Rate. If by reason of an Event of Default,
Bank elects to declare the Note to be immediately due and payable, then any
yield maintenance fee with respect to a LIBOR Based Loan shall become due and
payable in the same manner as though Company had exercised such right of
prepayment. In the event that the Bank shall be entitled to compensation
pursuant to this provision, it shall promptly notify the Company of the event by
reason of which it has become so entitled. The Company shall pay the Bank the
amount shown as due on any such notification within fifteen (15) days after
receipt thereof.

LINE OF CREDIT NOTE

Date: __________, 2005

$2,000,000.00                      Office Address:  300 Broad Hollow Road
                                                    Melville, New York 11747

           On April 1, 2006 (maturity date) for value received, the undersigned
jointly and severally promise(s) to pay to the order of FLEET NATIONAL BANK, a
Bank of America company, a national banking association, (hereinafter called the
Bank) at its Office in the place first above stated, or such other address as
the holder hereof may designate, in immediately available funds, the sum of TWO
MILLION AND 00/100 ($2,000,000.00) DOLLARS, or, the aggregate unpaid principal
amount of all loans made by the Bank to the undersigned hereunder, whichever is
less. The undersigned also promises to pay interest at said office in like money
on the unpaid principal amount hereof from time to time outstanding prior to
maturity at an annual rate equal to the rate(s) specified in paragraph 1 of the
attached Rider. Interest shall be payable on the 1st day of each month
commencing on April 1, 2005 and on the maturity hereof. Interest shall be
calculated on the basis of a 360-day year and actual days elapsed, provided that
any interest so calculated hereunder shall in no event be in excess of the
maximum permitted under applicable law. Upon and following an Event of Default
(as defined below) and/or after maturity, whether after stated maturity,
acceleration or otherwise, and/or after judgment has been rendered on this note,
this note, and, to the extent not specifically provided elsewhere to the
contrary and to the extent permitted by applicable law, any interest, fee or
other amount due in connection with the Liabilities (as hereinafter defined),
shall bear interest at a per annum rate determined daily and payable on demand
which shall be 4% in excess of the rate hereinbefore provided, but in no event
in excess of the maximum rate of interest permitted under applicable law. All
payments made in connection with this note and the documents, instruments and
agreements executed pursuant hereto or in connection herewith (collectively the
"Loan Documents") shall be in lawful money of the United States of America in
immediately available funds, without counterclaim or setoff and free and clear
of, and without any deduction for, any taxes or other payments. All payments
shall be applied first to the payment of all fees, expenses and other amounts
due to the Bank (excluding principal and interest), then to accrued interest,
and the balance on account of outstanding principal; provided, however, that
after default, payments will be applied to the obligations of the undersigned to
the Bank as Bank determines in its sole discretion. If this note or any payment
hereunder becomes due on a day which is not a Business Day, the due date of this
note or payment shall be extended to the next succeeding Business Day, and such
extension of time shall be included in computing interest and fees in connection
with such payment. If the entire amount of principal and/or interest required to
be paid pursuant to this note or the Loan Documents is not paid in full within
ten (10) days after the same is due, whether at maturity, upon acceleration or
otherwise, if permitted by applicable law, the undersigned shall pay to the Bank
a late fee equal to five percent (5%) of the required payment. The Bank is
authorized (but not required) to charge principal and interest and all other
amounts due under this note to any account of the Borrower with the Bank when
and as it becomes due.

The making of a loan, at any time, shall not be deemed a waiver of, or consent,
agreement or commitment by the Bank to the making of any future loan to the
undersigned.

Subject to the terms of this note, the undersigned may borrow, repay and
reborrow hereunder, provided that all outstanding principal and interest and any
other amounts due hereunder are paid in full on maturity. If any loan is made
hereunder, the Bank shall record on the books and records of the Bank an
appropriate notation evidencing any such loan, the rate of interest thereon,
each repayment on account of the principal thereof, and the amount of interest
paid, and the undersigned authorizes the Bank to maintain such records or make
such notations and agrees that the amount shown on the books and records as
outstanding from time to time shall constitute the amount owing to the Bank
pursuant to this note, absent manifest error; provided, however, the failure to
make any such record or notation with respect to any loan or payment shall not
limit or otherwise affect the obligations of the undersigned hereunder. No
portion of the proceeds of any loan shall be used, in whole or in part, for the
purpose of purchasing or carrying any "margin stock" as such term is defined in
Regulation U of the Board of Governors of the Federal Reserve System.

Any loan may be prepaid in whole or in part at any time and from time to time
without premium or penalty together with interest accrued on the amount prepaid
to the date of any such prepayment.

As collateral security for the payment of this note and for all other notes
and/or obligations or Liabilities (as hereinafter defined) of the Obligors
(which term as used herein shall be deemed to include each and all of the
undersigned), or any one or more of them, now or hereafter owed to, or held by,
the Bank (and/or any entity controlling, controlled by or under common control
with the Bank, each such entity referred to herein as an "Affiliate"), the
undersigned hereby grants to the Bank a security interest in and transfers and
assigns to the Bank the following property: (i) any and all monies and/or other
property now or hereafter held by the Bank and/or any Affiliate on deposit, in
safekeeping, or otherwise, for the account of or to the credit of or belonging
to any Obligor or in which any Obligor shall have any interest and (ii) any and
all property described on the "Schedule of Specific Possessory Collateral" on
the reverse side hereof, together with any additions and accessions thereto and
substitutions therefor and the products and proceeds thereof. This note and all
of the aforementioned obligations and Liabilities are also secured by (a) any
and all property of any Obligor now or hereafter subject to a security
agreement, pledge agreement, assignment, hypothecation or other document
granting the Bank or any Affiliate a security interest or other lien or
encumbrance with respect to the Liabilities evidenced by this note and (b) any
and all collateral described in any and all credit accommodations, notes, loan
agreements, and any other agreements and documents, now or hereafter existing,
creating, evidencing, guaranteeing, securing or relating to any or all of the
Liabilities evidenced by this note, together with all amendments, modifications,
renewals, or extensions thereof. All of the property described in clauses (i),
(ii), (a) and (b) shall be collectively referred to herein as the "Collateral".
At any time, without demand or notice (any such notice being expressly waived by
the undersigned), if permitted by applicable law, the Bank may setoff all
deposits, credits, collateral and property, now or hereafter in the possession,
custody, safekeeping or control of the Bank or any of its Affiliates, or in
transit to any of them, or any part thereof and apply the same to any of the
Liabilities even though unmatured and regardless of the adequacy of any other
collateral securing the Liabilities. ANY AND ALL RIGHTS TO REQUIRE THE BANK TO
EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH
SECURES THE LIABILITIES, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO
SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF ANY OBLIGOR, ARE HEREBY KNOWINGLY,
VOLUNTARILY AND IRREVOCABLY WAIVED. The term "Liabilities" shall include this
note and all other indebtedness and obligations and liabilities of any kind of
any Obligor to the Bank, now or hereafter existing, arising directly between any
Obligor and the Bank or acquired by assignment, conditionally or as collateral
security by the Bank, absolute or contingent, joint and/or several, secured or
unsecured, due or not due, contractual or tortious, liquidated or unliquidated,
arising by operation of law or otherwise, direct or indirect, including, but
without limiting the generality of the foregoing, indebtedness, obligations or
liabilities to the Bank or any Obligor as a member of any partnership,
syndicate, association or other group, and whether incurred by any Obligor as
principal, surety, endorser, guarantor, accommodation party or otherwise. Each
Obligor (if more than one, jointly and severally) hereby agrees that on demand
at any time and from time to time they will deposit and pledge with the Bank
additional collateral of a kind and of a market value required by it further to
secure any indebtedness or liabilities aforesaid.

If any of the following events shall occur (each an "Event of Default"):

                     (i) the occurrence of an "event of default" as such term is
           defined in the line letter dated March __, 2005 of the Bank to the
           undersigned; or

                     (ii) the undersigned fails to comply with any of the terms
           and provisions of this note.

the Liabilities shall become absolute, and immediately due and payable without
demand or notice to any Obligor. Upon default in the due payment of this note or
any other Event of Default or whenever this note or any payment of principal or
interest hereof shall become due in accordance with any of the provisions
hereof, the Bank may, but shall not be required to (1) proceed to apply to the
payment hereof the balance of any account or accounts maintained with the Bank
or any Affiliate by any Obligor and (2) sell (without demand of performance,
advertisement, notice of intention to sell, notice of time or place of sale,
notice to redeem or other notice whatsoever, all of which are hereby waived) all
or any part of the Collateral (on all of which the Obligor does hereby give to
the Bank a continuing lien, security interest and/or right of setoff) at public
or private sale or sales, or at any exchange or broker's board, or at the Bank's


                                       2
<PAGE>
office, at such prices as it shall deem best, for cash or credit, with the right
of the Bank at such sale to purchase all or any part thereof, free from any
right or equity of redemption, applying the net proceeds of such sale to the
payment of this note and of any other liabilities, claims or obligations to the
Bank of any of the Obligors, or of any partnership in which any of the Obligors
is a partner, all of whom together with any endorser or guarantor hereby
expressly agree to remain jointly and severally liable for any deficiency. The
Bank may exercise any other right or remedy hereby granted or allowed to it by
law, including but not limited to, the rights and remedies of a Secured Party
under the Uniform Commercial Code of the Governing State (which term as used in
this note shall mean the state in which the office indicated above opposite
"Office Address" is located; provided, that, if no such office is so indicated
then Governing State shall mean the state where the Bank's office that
originated the loan evidenced by this note is located), and each and every right
and remedy hereby granted to the Bank or allowed to it by law shall be
cumulative and not exclusive of one of the other rights or remedies, and may be
exercised by the Bank from time to time and as often as may be necessary. The
Bank shall have at any time in its discretion the right to enforce collection
and payment or liquidation of any of the Collateral by appropriate action or
proceedings, and the net amounts received therefrom, after deducting all costs
and expenses incurred in connection therewith, shall be applied on account of
this note and any other indebtedness or liabilities of the Obligor aforesaid,
all without notice to any Obligor. Any demand or notice, if made or given, shall
be sufficiently made upon or given to any Obligor if left at or mailed to the
last address of such Obligor known to the Bank or if made or given in any other
manner reasonably calculated to come to the attention of such Obligor or the
personal representatives, successors or assigns of such Obligor, whether or not
in fact received by them respectively. Unless the Collateral is perishable or
threatens to decline speedily in value or is of a type customarily sold on a
recognized market, the Bank will give the undersigned reasonable notice of the
time and place of any public sale thereof or of the time after which any private
sale or other intended disposition is to be made. Ten (10) days prior notice
shall be deemed reasonable notice. The Bank may assign and transfer this note to
any other person, firm or corporation and may deliver and repledge the
Collateral or any part thereof to the assignee or transferee of this note, who
shall thereupon become vested with all the powers and rights above given to the
Bank in respect thereof, and the Bank shall thereafter be forever released and
discharged of and from all responsibility or liability to the Obligor for or on
account of the Collateral so delivered. If an attorney is used to enforce or
collect this note, the undersigned agrees to pay the Bank's reasonable attorneys
fees. The undersigned jointly and severally promises to pay on demand all
expenses of any nature as soon as incurred whether in or out of court and
whether incurred before or after this note shall become due at its maturity date
or otherwise and costs which the Bank may deem necessary or proper in connection
with the satisfaction of the indebtedness or the administration, supervision,
preservation, protection (including but not limited to maintenance of adequate
insurance) or of the realization upon the Collateral. THE BANK (BY ACCEPTANCE OF
THIS NOTE) AND THE UNDERSIGNED MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY,
INTENTIONALLY AND IRREVOCABLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF
ANY CLAIM ARISING OUT OF, UNDER, OR IN CONNECTION WITH THIS NOTE OR ANY OTHER
LOAN DOCUMENTS, OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS
(WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING, WITHOUT
LIMITATIONS, ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF
THE BANK RELATING TO THE ADMINISTRATIONS OF THE LOAN OR ENFORCEMENT OF THE LOAN
DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION
WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.
THE UNDERSIGNED CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF THE BANK
HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE BANK WOULD NOT, IN THE EVENT
OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER. THIS WAIVER CONSTITUTES A
MATERIAL INDUCEMENT FOR THE BANK TO ACCEPT THIS NOTE AND MAKE THE LOAN. THIS
WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR THE BANK TO ACCEPT THIS NOTE AND
ENTER INTO THE LOAN TRANSACTION EVIDENCED BY THIS NOTE. The note shall be deemed
to have been made and delivered in the Governing State. The undersigned consents
to the jurisdiction of the state and federal courts of the Governing State in
any action brought to enforce any rights of the Bank under this note. The rights
and obligations of the parties under this note shall be construed and
interpreted in accordance with the laws of the Governing State (excluding the
laws applicable to conflicts or choice of law). This note and any other
agreements, documents and instruments executed and delivered pursuant to or in


                                       3
<PAGE>
connection with the Liabilities contain the entire agreement between the parties
relating to the subject matter hereof and thereof. All prior or contemporaneous
promises, agreements and understandings, whether oral or written, are deemed to
be superseded by the Loan Documents, and no party is relying on any promise,
agreement or understanding not set forth in the Loan Documents. The undersigned
expressly acknowledges that the Bank has not made and the undersigned is not
relying on any oral representations, agreements or commitments of the Bank or of
any officer, employee, agent or representative thereof. No change, modification,
termination, waiver, or discharge, in whole or in part, of this instrument shall
be effective unless in writing and signed by the party against whom such change,
modification, termination, waiver, or discharge is sought to be enforced.

All agreements between the Obligors and the Bank are hereby expressly limited so
that in no contingency or event whatsoever, whether by reason of acceleration of
maturity of the indebtedness evidenced hereby or otherwise, shall the amount
paid or agreed to be paid to the Bank for the use or the forbearance of the
indebtedness evidenced hereby exceed the maximum permissible rate under
applicable law. As used herein, the term "applicable law" shall mean the law in
effect as of the date hereof provided, however, that in the event there is a
change in the law which results in a higher permissible rate of interest, then
this note shall be governed by such new law as of its effective date. In this
regard, it is expressly agreed that it is the intent of the undersigned and the
Bank in the execution, delivery and acceptance of this note to contract in
strict compliance with the laws of the Governing State from time to time in
effect. If, under or from any circumstances whatsoever, fulfillment of any
provision hereof or of any of the Loan Documents at the time of performance of
such provision shall be due, shall involve transcending the limit of such
validity prescribed by applicable law, then the obligation to be fulfilled shall
automatically be reduced to the limits of such validity, and if under or from
circumstances whatsoever the Bank should ever receive as interest an amount
which would exceed the highest lawful rate, such amount which would be excessive
interest shall be applied to the reduction of the principal balance evidenced
hereby and not to the payment of interest. This provision shall control every
other provision of all agreements between each and every Obligor and the Bank.

There being more than one Obligor, the following provisions shall apply: (a)
Each Obligor agrees that it is jointly and severally, directly, and primarily
liable to Bank for payment in full of the Liabilities and that such obligation
is independent of the duties, obligations, and liability of each and all of the
other joint and several Obligors. Bank may bring a separate action or actions on
the Liabilities against each, any, or all of the Obligors, whether action is
brought against any other or all of such Obligors or any one or more of the
Obligors is or is not joined therein; (b) Each Obligor agrees that any release
that may be given by Bank to any one or more of the Obligors or any guarantor of
the Liabilities shall not release any other Obligor from its obligations
hereunder; (c) Each Obligor hereby waives any right to assert against Bank any
defense (legal or equitable), setoff, counterclaim, or claims that such Obligor
individually may now or any time hereafter have against another Obligor or any

                               LINE OF CREDIT NOTE


           This Rider to Line of Credit Note is made this _____ day of ________,
2005 and is incorporated into and shall be deemed to amend and supplement that
certain Line of Credit Note from KSW, INC. with an address at 37-16 23rd Street,
Long Island City, New York 11101 (the "Obligor") in favor of Fleet National
Bank, a Bank of America company, a national banking association organized and
existing under the laws of the United States of America with a usual place of
business at 300 Broad Hollow Road, Melville, New York 11747 (the "Note").

           The Obligor and the Bank agree that the Note is hereby amended and
supplemented as follows:

1. Prime/LIBOR Pricing Option. (a) The outstanding principal of all advances
under the Note shall accrue interest, at the Obligor's option, from time to
time, at either:

                               (i) For Loans fully secured by the Collateral
           Requirement without reference to any Excess, as defined in the Line
           Letter, the Loans shall bear interest at a rate per annum to be
           elected by the Obligor in accordance with the notice provisions in
           contained in Section 3 below (at the Obligor's option subject to
           availability) equal to the following: (y) the Prime Rate, as defined
           below, plus one-quarter of one (.25%) percent (the "Variable Rate"),
           or (z) the LIBOR Rate, as defined below, plus one and one-quarter
           (1.25%) percent per annum (the "Adjusted LIBOR Rate")

                               (ii) For Loans, if any, expressly authorized by
           the terms of the Line Letter in excess of the Collateral Requirement,
           a rate of interest equal to the Variable Rate plus three-quarters of
           one (.75%) percent ("Variable Rate Unsecured", together with the
           Variable Rate Loans hereinafter, the "Prime Based Loans") or (z) the
           Adjusted LIBOR Rate plus one and one-quarter (1.25%) percent
           ("Adjusted LIBOR Rate Unsecured", which together with the Adjusted
           LIBOR Rate Loans, the "LIBOR Based Loans").

                     (b) LIBOR Based Loans shall be available for an interest
period of one month (the "Interest Period"). In no event shall any
LIBOR Based Loan Interest Period continue beyond the expiration of the Credit
Period. Loans shall be in minimum amounts of $100,000.00 with respect to Prime
Based Loans and $250,000.00 with respect to LIBOR Based Loans, or an integral
multiple of $100,000 in excess thereof. The outstanding principal balance of any
Loan may be converted from a Prime Based Loan to a LIBOR Based Loan, or from a
LIBOR Based Loan to a Prime Based Loan, provided that LIBOR Based Loans may only
be converted on the last day of the Interest Period applicable thereto and the
required prior notice must be provided in connection with the conversion of a
Prime Based Loan to a LIBOR Based Loan. Loans under the Line shall be evidenced
by a note in an amount equal to the maximum aggregate amount of Loans hereunder
(the "Note"). The Note shall contain standard provisions with regard to LIBOR
Based Loans for illegality, inability to determine rate, indemnification for
break funding, and increased cost or reduced return.

For any principal amount due under the Note, from time to time, with respect to
which the LIBOR Rate has not been designated in accordance with the provisions
contained herein, interest shall accrue at the Prime Rate, plus the applicable
margin.

For the purposes of this Note, the following terms shall have the following
meaning:

"Business Day" shall mean any day other than a Saturday, Sunday, or other day on
which commercial banks in the Governing State are authorized or required to
close under the laws of the Governing State and, if the applicable day relates
to a LIBOR Based Loan or an Interest Period for a LIBOR Based Loan, the day on
which dealings in dollar deposits are also carried on in the London interbank
market and banks are open for business in London.

London Interbank Offered Rate ("LIBOR") shall mean, as applicable to any LIBOR
Based Loan, the rate per annum as determined on the basis of the offered rates
for deposits in U.S. Dollars, for a period of time comparable to such LIBOR

<PAGE>
Based Loan 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 first day of such LIBOR
Based Loan; 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 time comparable to
such LIBOR Based Loan 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
London Banking Days preceding the first day of such LIBOR Based Loan as selected
by the Bank. 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
period of time comparable to such LIBOR Based Loan offered by major banks in New
York City at approximately 11:00 a.m. New York City time, on the day that is two
London Banking Days preceding the first day of such LIBOR Based Loan. In the
event that the Bank is unable to obtain any such quotation as provided above, it
will be deemed that LIBOR pursuant to a LIBOR Based 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 the Bank, 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 1 minus the
Reserve Percentage. "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."

"Interest Period" shall mean with respect to any LIBOR Based Loan, any period
commencing on the date such LIBOR Based Loan is made or the date of a subsequent
interest rate selection, as the case may be, and ending one month later,
provided that: (y) any Interest Period which would otherwise end on a day which
is not a Business Day shall end on the next preceding or succeeding Business Day
as is the custom in the London interbank market to which such advance relates;
(z) each Interest Period which commences before and would otherwise end after
the Maturity Date shall end on the Maturity Date.

 "Prime Rate" shall mean the variable per annum rate of interest so designated
from time to time by Fleet National Bank as its prime rate. The Prime Rate is a
reference rate and does not necessarily represent the lowest or best rate being
charged to any customer. Changes in the rate of interest resulting from changes
in the Prime Rate shall take place immediately without notice or demand of any
kind.

2. Prepayment. Loans may be prepaid in whole or in part in a minimum amount of
$250,000.00 for LIBOR Based Loans and $100,000.00 for Prime Based Loans,
provided however, that any prepayment of any LIBOR Based Loan shall be subject
to the following LIBOR Indemnification Provisions. The Obligor shall pay to the
Bank, upon request of Bank, such amount or amounts as shall be sufficient (in
the reasonable opinion of the Bank) to compensate it for any loss, cost or
expense incurred as a result of: (i) any payment of a LIBOR Based Loan on a date
other than the last day of the Interest Period for such Loan; (ii) any failure
by the Obligor to borrow a LIBOR Based Loan on the date specified by Obligor's
written notice; (iii) any failure by the Obligor to pay a LIBOR Based Loan on
the date for payment specified in the Obligor's written notice. Without limiting
the foregoing, the Obligor shall pay to the Bank a "yield maintenance fee", if
any, in an amount computed as follows: the current rate for United States
Treasury securities (bills on a discounted basis shall be converted to a bond
equivalent) with a maturity date closest to the term chosen pursuant to the
LIBOR Rate Election as to which the prepayment is made, shall be subtracted from
the LIBOR in effect at the time of prepayment. If the result is zero or a
negative number, there shall be no yield maintenance fee. If the result is a
positive number, then the resulting percentage shall be multiplied by the amount
of the principal balance being prepaid. The resulting amount shall be divided by
360 and multiplied by the number of days remaining in the term chosen pursuant
to the LIBOR Rate Election as to which the prepayment is made. Said amount shall
be reduced to present value calculated by using the above referenced United
States Treasury securities rate and the number of days remaining in the term
chosen pursuant to the LIBOR Rate Election as to which prepayment is made. The
resulting amount shall be the yield maintenance fee due to the Bank upon the
payment of a LIBOR Based Loan. Each reference in this paragraph to "LIBOR Rate
Election" shall mean the election by Obligor of the LIBOR Rate. If by reason of


                                       2
<PAGE>
an Event of Default, the Bank elects to declare the Note to be immediately due
and payable, then any yield maintenance fee with respect to a LIBOR Based Loan
shall become due and payable in the same manner as though the Obligor had
exercised such right of prepayment.

3. Request for Advances. Loans shall be extended upon the Obligor's prior
written notice to the Bank (duly executed by an authorized officer of the
Obligor, such notice to be in a form satisfactory to the Bank which may be
accomplished by facsimile transmission. Each such notice shall be accompanied by
detailed information satisfactory in all respects to the Bank regarding (if
applicable) the proposed uses by the Obligor for the proceeds of any Loan then
being requested. Such notice shall be given at least one Business Day prior to
any requested Prime Based Loan, as hereinafter defined, and at least three
Business Days prior to any requested LIBOR Based Loan, as hereinafter defined.
Such notice shall specify whether the requested Loan is a Loan under the secured
portion of this line or the unsecured portion of same. The Bank shall not be
obligated to advance any Loans under this Line while the Obligor is in default
hereunder.

4. Renewal or Conversion. The Obligor may elect from time to time, to convert
all or a part of one type of loan into another type of loan or to renew all or
part of a loan by giving the Bank notice at least one (1) Business Day before
the conversion to a Prime Based Loan, and at least three (3) Business Days
before the conversion to or renewal of a LIBOR Based Loan, specifying (i) the
renewal or conversion date; (ii) the amount of the loan to be converted or
renewed; and (iii) in the case of conversions, the type of loan to be converted
to; provided that (a) the minimum principal amount of each Loan outstanding
after renewal or conversion shall be Two Hundred Fifty Thousand and 00/100
Dollars ($250,000.00) in the case of a LIBOR Based Loan; and (b) a LIBOR Based
Loan may be converted only on the last day of the Interest Period for such Loan.
At the time a LIBOR Based Loan is renewed, the Bank shall notify the Obligor of
the new interest rate. At the Bank's option, such notification may be by
telephone. All notices under this paragraph to be given by the Obligor shall be
subject to the same provisions applicable to advances and shall be irrevocable
and shall be given not later than 11:00 a.m. (Governing State time) on the day
which is not less than the number of Business Days specified above for such
notice. If the Obligor shall fail to give the Bank the notice as specified above
for the renewal or conversion of a LIBOR Based Loan prior to the end of the
Interest Period with respect thereto, such LIBOR Based Loan shall automatically
be converted to a Prime Based Loan on the last day of the Interest Period for
such Loan.

5. Miscellaneous LIBOR Provisions. (a) If the Bank determines that the effect of
an applicable law or government regulation, guideline or order or the
interpretation thereof by any governmental authority charged with the
administration thereof (such as, for example, a change in official reserve
requirements which the Bank is required to maintain in respect of loans or
deposits or other funds procured for funding such loans) is to increase the cost
to the Bank of making or continuing a LIBOR Based Loan hereunder or to reduce
the amount of any payment of principal or interest receivable by the Bank
thereon, then the Obligor shall pay to the Bank on demand such additional
amounts as the Bank may determine in its sole and absolute discretion, to be
required to compensate the Bank for such additional costs or reduction. Any
additional payment under this section will be computed from the effective date
at which such additional costs have to be borne by the Bank. A certificate as to
any additional amounts payable pursuant to this section setting forth the basis
and method of determining such amounts shall be conclusive, absent manifest
error, as to the determination by the Bank set forth therein if made reasonably
and in good faith. The Obligor shall pay any and all amounts so certified to it
by the Bank within ten (10) days of receipt of such certificate.

(b) In the event, and on each occasion, that on the day two (2) Business Days
prior to the commencement of any Interest Period for a LIBOR Based Loan, the
Bank shall have determined (i) that dollar deposits in the amount of the
requested principal amount of such LIBOR Based Loan are not generally available
in the London interbank market, (ii) that the rate at which such dollar deposits
are being offered will not adequately and fairly reflect the cost to the Bank of
making or maintaining such LIBOR Based Loan during such Interest Period, or
(iii) that reasonable means do not exist for ascertaining the LIBOR rate, the
Bank shall, as soon as practicable thereafter, give written notice or telex
notice of such determination to the Obligor. In the event of any such
determination, until the circumstances giving rise to such notice no longer
exist, no LIBOR Based Loan will be made hereunder. Each determination by the
Bank hereunder shall be conclusive absent manifest error.


                                       3
<PAGE>
(c) Notwithstanding anything to the contrary contained herein, if any change in
any law or regulation or with the administration or interpretation thereof shall
make it unlawful for the Bank to make or maintain any LIBOR Based Loan, then, by
written notice to the Obligor, the Bank may: (i) declare that LIBOR Based Loans
will not thereafter be made by the Bank hereunder, whereupon the Obligor shall
be prohibited from requesting LIBOR Based Loans from the Bank hereunder unless
such declaration is subsequently withdrawn; and (ii) require that all
outstanding LIBOR Based Loans made by it be converted to Prime Based Loans, in
which event (x) all such LIBOR Based Loans shall be automatically converted into
Prime Based Loans as of the effective date of such notice as provided for
herein, and (y) all payments and prepayments of principal which would otherwise
be applied to repay the converted LIBOR Based Loans shall instead be applied to
repay the Prime Based Loans resulting from the conversion of such LIBOR Based
Loans. For purposes of this section, a notice to the Obligor by the Bank shall
be effective on the day of receipt by the Obligor.

6. Pricing Options and Interest after Default, Maturity, Judgment. Upon default
or after maturity or after judgment has been rendered on the Note, the Obligor's
right to select pricing options shall cease and the unpaid principal of all
advances shall, at the option of the Bank, accrue interest at a rate which is
equal to the lesser of (i) four (4) percentage points per annum greater than the
Prime Rate or (ii) the maximum interest rate permitted by law.

           This Rider shall amend and supplement the Note. In the event of a
conflict between the terms of the Note and this Rider, the terms of this Rider
shall control. The Bank and the Obligor agree that this Rider shall be annexed
to the Note to evidence the modification of its terms as set forth herein. The
Obligor further acknowledges and agrees that all of the terms and conditions of
the Note shall remain in full force and effect, except as expressly modified
herein.

           IN WITNESS WHEREOF, this Rider is executed as of the date and year
first above written.

limitation, the roll-over or reinvested proceeds of the foregoing. Any delivery
or transfer of any of the Pledged Collateral to an agent or custodian designated
by the Bank shall be deemed a delivery or transfer to the Bank.

2. SECURITY INTEREST. The Pledgor hereby pledges, hypothecates, and impresses
the Pledged Collateral with a lien in favor of the Bank, and grants to the Bank
a security interest in the Pledged Collateral (which shall be a first priority
lien), to secure the punctual payment and performance of all the Liabilities.

3. PLEDGOR'S ADDITIONAL OBLIGATIONS. The Pledgor agrees that: (1) any
distribution in kind received by the Pledgor from any party for or on account of
the Pledged Collateral, including distributions of stock as a dividend or split
of any of the Pledged Collateral, option or rights, whether as an addition to,
in substitution of, or exchange for any instruments issued under or in respect
of the Pledged Collateral (which shall also be deemed to be included in the
Pledged Collateral) shall be accepted by the Pledgor as agent for the Bank and
the Pledgor shall hold same in trust on behalf of and for the benefit of the
Bank and shall immediately deliver in the form received with any required
endorsement; (2) additional collateral in form and kind satisfactory to the Bank
will be deposited by the Pledgor with the Bank if the Bank at any time deems the
Pledged Collateral insufficient or unsatisfactory; (3) any note or other

<PAGE>
instrument executed and delivered to the Pledgor by any party to evidence any
obligation of such party with respect to the Pledged Collateral shall be
immediately delivered with any required endorsement to the Bank. All such items
shall be held by the Bank in accordance with the terms of this Pledge Security
Agreement.

The Pledgor agrees to pay to the Bank on demand all reasonable fees, costs and
expenses incurred by the Bank in connection with the administration of this
Pledge Security Agreement, including, without limitation, overnight courier
fees, lien search fees, and filing and recording fees.

The Pledgor shall deliver to the Bank all stock certificates, stock powers,
documents or instruments evidencing the Pledged Collateral and shall execute
(with signatures guaranteed when requested by the Bank) and deliver to the Bank
and/or third parties designated by the Bank such additional documents, notices,
requests and other instruments as the Bank deems necessary or advisable to
confirm, effect or preserve the pledge or perfection of the Bank's security
interest in the Pledged Collateral and to protect the Bank's rights under this
Pledge Security Agreement.

4. REQUIRED VALUE OF COLLATERAL. The Margin Value of the Pledged Collateral (as
defined below) must equal the outstanding principal amount of the Liabilities
(the "Required Value"). If at any time the Required Value of the Pledged
Collateral is less than the then outstanding principal amount of the
Liabilities, the Pledgor must immediately (i) repay the Liabilities by at least
the amount necessary such that the Required Value of the Pledged Collateral at
that time is at least equal to the then outstanding Liabilities, or (ii) pledge
and deliver additional Pledged Collateral to the Bank (in form acceptable to the
Bank) in an amount such that the Margin Value of the Pledged Collateral at least
equals the then outstanding Liabilities. Upon request of the Bank from time to
time, and at least monthly, the Pledgor will provide evidence of the fair market
value of the Pledged Collateral.

"Margin Value" shall mean the following percentages of fair market value for the
following types of collateral:

Collateral which is in book-entry form in the Federal Reserve System

Federal Reserve Bank of Boston. Upon receipt of Book-Entry Collateral, the Bank
shall promptly send to the Pledgor written confirmation of such receipt, which
confirmation shall identify the type and amount of such Book-Entry Collateral.

6. CERTAIN RIGHTS AND DUTIES OF BANK. The Pledgor acknowledges that: the Bank
has no duty of any type with respect to the Pledged Collateral except for the
use of due care in safekeeping any of the Pledged Collateral actually in the
physical custody of the Bank; prior to the occurrence of any event of default
described in the succeeding paragraph, the Bank's rights with respect to the
Pledged Collateral shall be limited to the Bank's rights as a secured party and
pledgee and the right to perfect its security interest, preserve, enforce and
protect the lien granted hereunder and its interest in the Pledged Collateral;
and the Bank may sell, assign or grant participations in any of the Liabilities


                                       2
<PAGE>
and any of the Pledged Collateral and that the Bank's purchaser, assignee or
participant shall have the same rights and privileges with respect to such
Liabilities and Pledged Collateral as the Pledgor grants to the Bank under this
Pledge Security Agreement. With respect to any Pledged Collateral with a stated
maturity date (including, without limitation, certificates of deposit and other
term accounts), the Bank is authorized and directed, upon maturity, to roll-over
and reinvest such Pledged Collateral in a similar investment, with such tenor
and interest rate or yield as the Bank, in its discretion, deems to be
reflective of prevailing market conditions. The Bank may, but shall not be
obligated to, at any time, before or after the occurrence of any event of
default, transfer the Pledged Collateral into or out of its own name or that of
its nominee, and the Bank or its nominee may receive any and all interest,
income and any distributions thereon, and hold the same as Pledged Collateral,
or apply the same to the Liabilities, whether or not an event of default has
occurred. Prior to the occurrence of any event of default described in the
succeeding paragraph, the Bank agrees that it will not vote any Pledged
Collateral constituting securities or closely held capital stock.

7. REPRESENTATIONS AND WARRANTIES. The Pledgor represents, warrants and agrees
that: (a) the Pledgor has good and valid title to the Pledged Collateral, free
and clear of any liens, charges or encumbrances thereon or affecting the title
thereto; (b) the Pledgor has good right and lawful authority to pledge, assign,
transfer, deliver, deposit, set over and confirm unto the Bank the Pledged
Collateral as provided herein and will warrant and defend the title thereto and
the security interest therein conveyed to the Bank by the Pledge Security
Agreement against all claims of all persons and will maintain and preserve such
security interest; (c) the execution, delivery and performance of the Pledge
Security Agreement (the "Agreement") and the pledge and/or delivery of the
Pledged Collateral to the Bank do not and will not contravene any agreement,
commitment, indenture, contract or other obligation or restriction affecting the
Pledgor; (d) the Agreement is the legal, valid and binding obligation of the
Pledgor, enforceable in accordance with its terms; (e) the Agreement will not
violate any provision of law applicable to the Pledgor; and (f) no
authorization, approval, or other action by, and no notice to or filing with,
any governmental authority or regulatory body is required for the pledge by
Pledgor of the Pledged Collateral pursuant to the Agreement or for the
execution, delivery, or performance of the Agreement by Pledgor. The Pledgor
covenants that it will have title to and right to pledge any other property of
the Pledgor at any time hereafter purported to be pledged to the Bank hereunder.

8. EVENTS OF DEFAULT; REMEDIES. Upon occurrence of any event of default under
any instrument evidencing any of the Liabilities or of any of the following
events: (1) default in the payment or performance of any other of the
obligations or liabilities of the Pledgor under any agreement between the Bank
and Pledgor; (2) the Pledgor, if a business entity, discontinues business
operations at any of the Pledgor's locations; (3) the Pledgor is generally
unable to pay debts as they become due or the Bank deems itself insecure; (4)
the Pledgor makes a general assignment for the benefit of creditors; (5) the
entry of a decree, order or order for relief by a court having jurisdiction of a
case initiated by or against the Pledgor under the federal bankruptcy code or
any other federal or state laws pursuant to which a receiver, liquidator,
assignee, custodian, trustee, sequestrator, debtor in possession, examiner or
other similar official, is appointed for the Pledgor or any of the Pledgor's
property, with or without consent, for any purpose whatsoever; (6) a substantial
part of the property of the Pledgor is taken by attachment, execution or any
other form of legal process; (7) the assertion of any levy, seizure or
attachment on the Pledged Collateral; or (8) death of an individual Pledgor or
dissolution or termination of legal existence of a corporate, limited liability
company, partnership or trust Pledgor; then the Bank, with or without notice to
the Pledgor and without demand for additional collateral, may, in addition to
any other rights set forth in this Agreement or available under applicable law,
(a) vote any Pledged Collateral constituting securities or closely held capital
stock; (b) sell at public or private sale any or all of the Pledged Collateral,
which the Bank may purchase free from any right of redemption; or, at its
discretion in its own name or in the name of the Pledgor take any action for the
collection of the Pledged Collateral, including the filing of a proof of claim
in insolvency proceedings, and may receive the proceeds thereof and execute
releases therefor. After deducting its expenses, including reasonable attorney's
fees (which may include costs allocated by the Bank's internal law department),
incurred in the sale or collection of the Pledged Collateral, the Bank shall
apply the proceeds to the Liabilities and shall account to the Pledgor for any
surplus. The Pledgor agrees that the Bank has no obligation to sell or otherwise
liquidate the Pledged Collateral in any particular order or to apply the
proceeds thereof to any particular portion of the Liabilities. The Pledgor
further agrees that after the occurrence of an event of default, the Bank shall
have no obligation to vote any Pledged Collateral constituting securities or
closely held capital stock.

In connection with any secured party's sale, the Bank is authorized, if it deems
it advisable to do so, in order to comply with any applicable securities laws,
to restrict the prospective bidders or purchasers to persons who will represent
and agree that they are purchasing the Pledged Collateral for their own account
for investment, and not with a view to the distribution or re-sale thereof.
Sales made subject to such restriction shall be deemed to have been made in a
commercially reasonable manner.

9. POWER OF ATTORNEY, ETC. The Pledgor hereby irrevocably constitutes and
appoints the Bank the true and lawful attorney-in-fact for and on behalf of the
Pledgor with full power of substitution and revocation in its own name or in the
name of the Pledgor, from time to time in the Bank's discretion, to take any
action and to execute any instrument which the Bank may deem necessary or
advisable to confirm, perfect, preserve, enforce or protect the pledge of the
security interest as herein contemplated, including, without limitation, to
indorse in favor of the Bank any of the Pledged Collateral; cause the transfer
of any of the Pledged Collateral in such name as the Bank may direct; cause the
issuance of certificates for book-entry and/or uncertificated securities; renew,
extend or roll over any Pledged Collateral; to receive, endorse and collect the

and record any and all financing statements, continuation statements,
assignments, proofs of claim, powers of attorney, leases, discharges or other
instruments or agreements which the Bank in its sole discretion may deem
necessary or advisable to perfect, preserve, enforce or protect the lien granted
hereunder and its interest in the Pledged Collateral and to carry out the
purposes of this Pledge Security Agreement, including but without limiting the
generality of the foregoing, any and all proofs of claim in bankruptcy or other
insolvency proceedings of the Borrower, with the right to collect and apply to
the Liabilities all distributions and dividends made on account of the Pledged
Collateral. The rights and powers conferred on the Bank by the Pledgor are
expressly declared to be coupled with an interest and shall be irrevocable until
all the Liabilities are paid and performed in full. A carbon, photographic, or
other reproduction of a security agreement (including this Pledge Security
Agreement) or a financing statement is sufficient as a financing statement. The
powers conferred on the Bank hereunder are solely to protect the interests of
the Bank in the Pledged Collateral and shall not impose any duty upon the Bank
to exercise any such powers. The Bank shall be accountable only for amounts that
it actually receives as a result of the exercise of such powers, and neither it
nor any of its officers, directors, employees or agents shall be responsible to
the Pledgor for any act or failure to act, except for its own willful misconduct
taken or omitted in bad faith.

10. MISCELLANEOUS. This Pledge Security Agreement and the Pledged Collateral
shall not be in any way affected by the extension of time or renewal of any of
the Liabilities, the modification in any manner or the taking or release in
whole or in part of any security therefor or the obligations of any endorsers,
sureties, guarantors or other parties or the granting of any other indulgences
to the Borrower or to the Pledgor. No termination of this Pledge Security
Agreement shall be effective in any event until the Bank in its discretion
determines that the Liabilities of the Borrower and Pledgor covered by this
Pledge Security Agreement have been satisfied in full.

In order to induce FLEET NATIONAL BANK, a national banking association (which
together with its successors, endorsees and assigns, is hereinafter called the
"Bank") to make such advances, loans or extensions of credit, directly or
indirectly, to KSW, INC. (hereinafter, whether one or more, called the
"Borrower") and to grant to the Borrower such renewals, extensions,
forbearances, releases of collateral or other relinquishments of rights as the
Bank may deem advisable, and for other valuable consideration, the receipt of
which is hereby acknowledged, the undersigned (hereinafter, whether one or more,
called the "Guarantor") who, if more than one, shall be jointly and severally
liable hereunder, hereby absolutely unconditionally guarantees to the Bank the
due and punctual payment when due, whether by acceleration or otherwise, in
accordance with the terms thereof, of the principal of and interest on and all
other sums payable with respect to any and every obligation or liability of the
Borrower to the Bank, whether now existing or hereafter incurred, whether
originally contracted with the Bank or with another and transferred to the Bank
or otherwise acquired by the Bank, whether contracted by the Borrower alone or
jointly with others, and whether absolute or contingent, secured or unsecured,
matured or unmatured, including, without limitation, all obligations and
liabilities of the Borrower to the Bank, whether existing or hereafter arising,
under any foreign exchange contracts, interest rate swap, cap, floor or hedging
agreements, or other similar agreements, and all obligations of the Borrower to
the Bank to repay overdrafts and other amounts due to the Bank under any
existing or future agreements relating to cash management services (such
obligations and liabilities of the Borrower being hereinafter collectively
called the "Liabilities"). Notwithstanding any language contained in this
Guaranty relating to loans, it is expressly intended, contemplated and agreed
that each Guarantor's obligations under this Guaranty shall extend to each and
all of the Liabilities, whether or not such Liabilities relate directly to
loans. All payments made in connection with this Guaranty shall be in lawful
money of the United States of America in immediately available funds, without
counterclaim or setoff and free and clear of, and without any deduction for, any
taxes or other payments.

As collateral security for the performance of this Guaranty and all other
obligations of the Guarantor to the Bank, whether now or hereafter owed to, or
held by, the Bank (and/or any entity controlling, controlled by or under common
control with the Bank, each such entity referred to herein as an "Affiliate"),
including, without limitation, the Liabilities, the Guarantor hereby grants to
the Bank a security interest in and transfers and assigns to the Bank the
following property: (i) any and all monies and/or other property now or
hereafter held by the Bank and/or any Affiliate on deposit, in safekeeping, or
otherwise, for the account of or to the credit of or belonging to any Guarantor
or in which any Guarantor shall have any interest (ii) any and all claims and
demands, presently existing or hereafter arising, and all interest heretofore or
hereafter accrued thereon, and any and all collateral or security interests
relating thereto and the proceeds thereof, which the Guarantor now has or may
hereafter have or acquire against the Borrower (such claims and demands referred
to herein as the "Claims") and (iii) any and all property described on the
"Schedule of Specific Possessory Collateral" on the reverse side hereof,
together with any additions and accessions thereto and substitutions therefore
and the products and proceeds thereof. This Guaranty is also secured by (a) any
and all property of the Guarantor now or hereafter subject to a security
agreement, mortgage, pledge agreement, assignment, hypothecation or other
document granting the Bank or any Affiliate a security interest or other lien or
encumbrance and (b) any and all collateral described in any and all credit
accommodations, notes, loan agreements, and any other agreements and documents,
now or hereafter existing, creating, evidencing, guaranteeing, securing or
relating to any or all of the Liabilities, together with all amendments,
modifications, renewals, or extensions thereof. All of the property described in
clauses (i), (ii), (iii), (a) and (b) above shall be collectively referred to
herein as the "Collateral". The Bank at any time, before or after an Event of
Default (as hereinafter defined), may, but shall not be obligated to, transfer
into or out of its own name or that of its nominee all or any of the Collateral,
including stocks, bonds, and other securities, and the Bank or its nominee may
demand, sue for, collect, receive and hold as like Collateral any or all
interest, dividends and income thereon and if any securities are held in the
name of the Bank or its nominee, the Bank may, after an Event of Default
exercise all voting and other rights pertaining thereto as if the Bank were the
absolute owner thereof; but the Bank shall not be obligated to demand payment
of, protest, or take any steps necessary to preserve any rights in the
Collateral against prior parties, or to take any action whatsoever in regard to
the Collateral or any part thereof, all of which the Guarantor assumes and
agrees to do. Without limiting the generality of the foregoing, the Bank shall
not be obligated to take any action in connection with any conversion, call,
redemption, retirement or any other event relating to any Collateral, unless the
Guarantor gives written notice to the Bank that such action shall be taken not
more than thirty (30) days prior to the time such action may first be taken and
not less than ten (10) days prior to the expiration of the time during which
such action may be taken. At any time, without demand or notice (any such notice
being expressly waived by the undersigned), if permitted by applicable law, the
Bank may setoff all deposits, credits, collateral and property, now or hereafter
in the possession, custody, safekeeping or control of the Bank or any of its
Affiliates, or in transit to any of them, or any part thereof and apply the same
to any of the Liabilities even though unmatured and regardless of the adequacy
of any other collateral securing the Liabilities. ANY AND ALL RIGHTS TO REQUIRE
THE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL
WHICH SECURES THE LIABILITIES, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH
RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER OR ANY
GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

The Guarantor hereby grants to the Bank full power, without notice to the
Guarantor or to the Borrower, and without in any way affecting the joint and
several obligations of each Guarantor hereunder, to deal in any manner with the
Borrower, the Liabilities, the Collateral and with any Guarantor hereunder, and
any other guarantor of the Liabilities including, without limitation, the
following powers: (a) to modify or otherwise change any terms of all or any part

<PAGE>
of the Liabilities and/or the Collateral, to grant any extension or renewal
thereof and any other indulgence with respect thereto, and to effect any
release, subordination, compromise or settlement with respect to the Borrower,
the Liabilities, the Collateral, and the obligations of any one or more of the
Guarantors; (b) to enter into any agreement of forbearance with respect to all
or any part of the Collateral, or with respect to the Liabilities of the
Borrower or the obligations of any Guarantor, or to change the terms of any such
agreement; (c) to forbear from calling for additional collateral to secure any
of the Liabilities or to secure any obligation comprised in the Collateral; and
(d) to consent to the substitution, exchange, or release of all or any part of
the Collateral, whether or not the collateral, if any, received by the Bank upon
any substitution, exchange, or release shall be of the same or of a different
character or value than the collateral surrendered by the Bank.

The Guarantor waives any notice of the acceptance of this Guaranty, or of the
creation, renewal or accrual of any of the Liabilities, present or future, or of
the reliance of the Bank upon this Guaranty. The Liabilities shall conclusively
be presumed to have been created, contracted for, incurred or suffered to exist
in reliance upon this Guaranty, and all dealings between the Borrower and the
Bank shall likewise be presumed to be in reliance upon this Guaranty. The
Guarantor waives protest, presentment, demand for payment, notice of default or
non-payment, and notice of dishonor to or upon the Guarantor, the Borrower, or
any other party liable for any of the Liabilities. The Guarantor acknowledges
that this Guaranty and the Guarantor's obligations under this Guaranty are and
shall at all times continue to be absolute and unconditional in all respects,
and shall at all times be valid and enforceable irrespective of (a) any other
agreements or circumstances of any nature whatsoever which might otherwise
constitute a defense to this Guaranty and the obligations of the Guarantor under
this Guaranty, (b) the obligations of any other person or party (including,
without limitation, the Borrower) relating to this Guaranty, or (c) the
obligations of the Guarantor under this Guaranty or otherwise with respect to
the Liabilities. The obligations of the Guarantor hereunder, and the rights of
the Bank in the Collateral, shall not be released, discharged or in any way
affected, nor shall the Guarantor have any rights against the Bank by reason of
the fact that the Bank fails to preserve any rights in the Collateral or in any
collateral granted by the Borrower to the Bank ("Other Collateral") or take any
action whatsoever in regard to the Collateral or Other Collateral or that any of
the Collateral or Other Collateral may be in default at the time of acceptance
thereof by the Bank or later; nor by reason of the fact that a valid lien on any
of the Collateral or Other Collateral may not be conveyed to, or created in
favor of, the Bank; nor by reason of the fact that any of the Collateral or
Other Collateral may be subject to equities or defenses or claims in favor of
others or may by invalid or defective in any way; nor by reason of the fact that
any of the Liabilities may be invalid or unenforceable against the Borrower or
any obligor thereon for any reason whatsoever; nor by reason of the fact that
the value of the Collateral or Other Collateral, if any, or the financial
condition of the Borrower, or of any obligee under the guarantee, if any, of the
Collateral or Other Collateral, may not have been correctly estimated or was
thereafter changed; nor by reason of an deterioration, waste, or loss by fire,
theft, or otherwise of any of the Collateral or Other Collateral nor by reason
of the release, in whole or in part, with or without consideration, of the
Collateral or Other Collateral or any of it.

In case the Borrower shall fail to pay all or any part of the Liabilities when
due, the Guarantor immediately will pay to the Bank the amount due and unpaid by
the Borrower under such Liabilities, in like manner as if such amount
constituted the direct and primary obligation of the Guarantor. The Bank shall
have its remedy under this Guaranty without being obliged to resort first to the
Borrower or the Collateral or the Other Collateral or to any other security or
to any other remedy or remedies to enforce payment or collection of the
Liabilities, and may pursue all or any of its remedies at one or at different
times. With respect to the Claims, the Bank shall have the full right on the
part of the Bank in its own name or in the name of the Guarantor to collect and
enforce such Claims by legal action, proof of debt in bankruptcy or other
liquidation proceedings, vote in any proceeding for the arrangement of debts at
any time proposed, or otherwise, the Bank and each of its officers being hereby
irrevocably constituted attorneys-in-fact for the Guarantor for the purpose of
such enforcement and for the purpose of endorsing in the name of the Guarantor
any instrument for the payment of money. The Guarantor will receive as trustee
for the Bank and will pay to the Bank forthwith upon receipt thereof any amounts
which the Guarantor may receive from the Borrower on account of the said Claims.
The Guarantor agrees that at no time hereafter will any of such Claims be
represented by any notes, other negotiable instruments or writings, except and
in such event they shall either be made payable to the Bank, or if payable to
the Guarantor, shall forthwith be endorsed by the Guarantor to the Bank. The
Guarantor agrees that no payment on account of such Claims or any security
interest therein shall be created, received, accepted or retained nor shall any
financing statement be filed with respect thereto by the Guarantor unless and
until the Borrower has paid and satisfied in full all the Liabilities. The Bank
is hereby authorized and empowered, upon the occurrence of any Event of Default,
to appropriate and apply to the payment and extinguishment of the Liabilities of
the Borrower and obligations of the Guarantor any and all claims, demands,
monies, property, securities, deposits, or credit balances without demand,
advertisement or notice, all of which are hereby expressly waived.

In the event that the Bank shall receive any payments on account of any of the
Liabilities, whether directly or indirectly, and it shall subsequently be
determined that such payments were for any reason improper, or a claim shall be
made against the Bank that the same were improper, and the Bank either
voluntarily, or pursuant to court order shall return the same, the Guarantor
shall be liable, with the same effect as if the said payments had never been
paid to, or received by, the Bank, for the amount of such repaid or returned
payments, notwithstanding the fact that they may theretofore have been credited
on account of the Liabilities or any of them. If the Guaranty hereunder with
respect to any Guarantor would be held or determined to be void, invalid or
unenforceable on account of the amount of such Guarantor's aggregate liability
under this Guaranty, then notwithstanding any other provision of this Guaranty
to the contrary, the maximum liability of such Guarantor hereunder shall be

<PAGE>
automatically limited and reduced to an amount equal to the maximum amount that
would not render this Guaranty with respect to such Guarantor void, invalid or
unenforceable. The invalidity or unenforceability of any portion of this
Guaranty shall in no way affect the validity or enforceability of any other
portion of this Guaranty.

If any of the following events shall occur (each an "Event of Default"): default
by the Borrower with respect to the Liabilities or by the Guarantor with respect
to the obligations or Liabilities of either of them to the Bank, or in case the
Borrower or any Guarantor shall die, or become insolvent, or be unable to meet
his or its debts as they mature, or make any assignment for the benefit of
creditors, or if an order for relief under the Federal Bankruptcy Code, as now
or hereafter in effect, shall be entered against the Borrower or any Guarantor,
or if a receiver, trustee or custodian of any kind (either at law or in equity)
of any of the property of the Borrower or of any Guarantor is appointed, or if a
judgment is obtained or a warrant of attachment issued against the Borrower or
any Guarantor, or if the financial or business condition of the Borrower or any
Guarantor shall so change as in the opinion of the Bank to impair materially the
Bank's security or increase its risk, or in the event of any default in the
performance of any obligation comprised in the Collateral or if the Bank in good
faith shall deem itself insecure, then the Liabilities of the Borrower and the
obligations of the Guarantor to the Bank, whether direct or contingent, and of
every description, shall, without notice or demand become immediately due and
payable and shall be paid forthwith by the Guarantor; and in such event the Bank
may sell or dispose of the whole or any part of the Collateral, at public or
private sale with or without any previous demand for performance to the
Guarantor or the Borrower. Any legal requirement of notice of any such sale or
other disposition shall be deemed satisfied by the giving of ten (10) days prior
written notice which shall also be deemed reasonable notice. If the Collateral
is perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, the Bank shall not be required to give
notice of public or private sale or other intended disposition of the
Collateral. The Bank may retain from the proceeds of any such sale all costs and
charges incurred by it in the said taking and sale or other disposal including
but not limited to attorneys' fees. If a deficit should remain after any such
sale or other disposal, the Guarantor will pay the same promptly upon demand to
the Bank. The Bank or its agent may bid and/or purchase free from any right or
equity of redemption at any such public or private sale. In any event the
Guarantor agrees to pay all costs, expenses and reasonable attorneys' fees if
any Liabilities of the Borrower or any obligations of the Guarantor to the Bank
are placed in the hands of an attorney for collection. Any stocks, bonds or
other securities held by the Bank hereunder may, whether or not the Borrower or
the Guarantor is in default, be registered and held in the name of the Bank or
its nominee, and after default the Bank or its nominee may exercise all voting
and other corporate rights as if the Bank were the absolute owner thereof. No
delay on the part of the Bank in exercising any power or right hereunder shall
operate as a waiver thereof; nor shall any single or partial exercise of any
power or right hereunder or the failure to exercise same in any instance
preclude other or further exercise thereof or the exercise of any other power or
right; nor shall the Bank be liable for exercising or failing to exercise any
such power or right; the right and remedies hereunder expressly specified are
cumulative and not exclusive of any rights or remedies which the Bank or any one
in whose behalf it has acted or shall act as herein provided, or its or his or
their transferees, may or will otherwise have.

The term "the Bank" as used throughout this instrument shall be deemed to
include Fleet National Bank, all of its branches and departments, and any
individual, partnership or corporation acting as its nominee or agent, and any
corporate subsidiary the stock of which is owned or controlled, directly or
indirectly, by FleetBoston Financial Corporation and its successors and assigns.
The term "Borrower" as used throughout this instrument shall include the
individual or individuals, association, partnership, limited liability company
or corporation named herein as the Borrower, and (a) any successor, individual
or individuals, association, partnership or limited liability company or
corporation to which all or substantially all of the business or assets of the
Borrower shall have been transferred, (b) in the case of a Borrower which is a
partnership or limited liability company, any new partnership or limited
liability company, as the case may be, which shall have been created by reason
of the admission of any new partner (member) or partners (members) therein or
the dissolution of the existing partnership (limited liability company) by the
death, resignation or other withdrawal of any partner (member), and (c) in the
case of a Borrower which is a corporation, any other corporation into or with
which the Borrower shall have been merged, consolidated, reorganized, purchased
or absorbed.

The Guaranty shall, without further reference, pass to and may be relied on and
enforced by any successor or assignee of the Bank, and any transferee or
subsequent holder of any of the Liabilities and the Borrower and/or the
Guarantor will not assert any claims it may have against the Bank against any
such assignee, successor, transferee, or any other subsequent holder. NO CLAIM
MAY BE MADE BY ANY GUARANTOR AGAINST THE BANK OR THE AFFILIATES, DIRECTORS,
OFFICERS, EMPLOYEES, ATTORNEYS OR AGENTS OF THE BANK FOR ANY SPECIAL, INDIRECT
OR CONSEQUENTIAL DAMAGES OR, TO THE FULLEST EXTENT PERMITTED BY LAW, FOR ANY
PUNITIVE DAMAGES IN RESPECT OF ANY CLAIM OR CAUSE OF ACTION (WHETHER BASED ON
CONTRACT, TORT, STATUTORY LIABILITY, OR ANY OTHER GROUND) BASED ON, ARISING OUT
OF OR RELATED TO THIS GUARANTY, THE LIABILITIES OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR ANY ACT, OMISSION OR EVENT OCCURRING IN CONNECTION THEREWITH, AND EACH
GUARANTOR HEREBY WAIVES, RELEASES AND AGREES NEVER TO SUE UPON ANY CLAIM FOR ANY
SUCH DAMAGES, WHETHER SUCH CLAIM NOW EXISTS OR HEREAFTER ARISES AND WHETHER OR
NOT IT IS NOW KNOWN OR SUSPECTED TO EXIST IN ITS FAVOR. This is a continuing

<PAGE>
guaranty, and is to remain in force throughout business relations between the
Borrower and the Bank, and until the payment of all Liabilities of the Borrower
to the Bank, whether now existing or hereafter incurred, notwithstanding the
appointment of a receiver of, or the dissolution of, and/or any other change in,
or with respect to the Borrower. No change, modification, waiver, or discharge,
in whole or in part, of this Guaranty shall be effective unless in writing and
signed by the party against whom such change, modification, waiver, or discharge
is sought to be enforced. However, this Guaranty may be terminated with respect
to the obligations of any of the Guarantors (but then only so far as it relates
to Liabilities arising after such termination), only upon written notice to that
effect delivered by such Guarantor to the Bank and receipt thereof acknowledged
in writing by an officer of the Bank. In the event of termination such Guarantor
and his, her or its respective executors, administrators and assigns shall
nevertheless remain liable with respect to the Liabilities theretofore created
or arising, and with respect to such Liabilities and any new renewals, or other
liabilities arising out of the same, this instrument shall continue in full
force and effect and the Bank shall have all the rights herein provided for as
if no such termination had occurred; and the Guarantors, if any, who have not
joined in such termination shall continue to be liable hereunder as if no such
termination had been effected. In addition to all rights and remedies granted
herein, the Bank shall have all of the rights of a Secured Party under the
Uniform Commercial Code of the Governing State (which term as used in this
Guaranty shall mean the state indicated as such below; provided, that, if no
such state is indicated then Governing State shall mean the state where the
Bank's office that originated the Liabilities is located). This Guaranty shall
be deemed to have been made in the Governing State, the Guarantor consents to
the jurisdiction of the state and federal courts of the Governing State, and the
rights and liabilities of the parties shall be determined in accordance with the
laws of the Governing State (excluding the laws applicable to conflicts or
choice of law).

The Guarantor has made an independent investigation of the Borrower and of the
financial condition of the Borrower. The Bank has not made and does not make any
representations or warranties as to the income, expense, operation, finances or
any other matter or thing affecting the Borrower nor has the Bank made any
representation or warranties as to the amount or nature of the Liabilities of
the Borrower to which this Guaranty applies as specifically herein set forth,
nor has the Bank or any officer, agent or employee of the Bank or any
representative thereof, made any other oral representations, agreements or
commitments of any kind or nature, and the Guarantor hereby expressly
acknowledges that no such representations or warranties have been made and the
Guarantor expressly disclaims reliance on any such representations or
warranties. It is agreed that all understandings and agreements heretofore had
between the parties hereto are merged in this Guaranty, which alone, fully and
completely, expresses their understanding.

The Guarantor agrees that this Guaranty shall continue to be effective or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
the principal of, interest on, or fees with respect to any of the Liabilities of
the Borrower is rescinded or must otherwise be restored or returned by the Bank
upon insolvency, bankruptcy or reorganization of the Borrower or the Guarantor,
or otherwise, all as though such payment has not been made.

If for any reason any of the Liabilities of the Borrower have been discharged or
have become irrecoverable from the Borrower by operation of law or for any other
reason, the liabilities of the Guarantor under this Guaranty shall nevertheless
remain in full force and effect notwithstanding such discharge or
irrevocability.

EACH GUARANTOR AND THE BANK (BY ACCEPTANCE OF THIS GUARANTY) KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY AND IRREVOCABLY WAIVE THE RIGHT TO A TRIAL BY JURY
IN ANY PROCEEDING HEREAFTER INSTITUTED BY OR AGAINST THE GUARANTOR OR THE BANK
IN RESPECT OF THIS GUARANTY OR ARISING OUT OF, UNDER OR IN CONNECTION WITH ANY
OTHER LOAN DOCUMENTS, OR ANY COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR
WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING, WITHOUT LIMITATION, ANY COURSE OF
CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF THE BANK RELATING TO THE
ADMINISTRATION OF THE LIABILITIES OR ENFORCEMENT OF THIS GUARANTY OR THE LOAN
DOCUMENTS, AND AGREE THAT EACH GUARANTOR AND THE BANK WILL NOT SEEK TO
CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT
BE OR HAS NOT BEEN WAIVED. EXCEPT AS PROHIBITED BY LAW, THE GUARANTOR HEREBY
WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ANY SPECIAL,
EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN OR IN
ADDITION TO, ACTUAL DAMAGES. THE GUARANTOR CERTIFIES THAT NO REPRESENTATIVE,
AGENT OR ATTORNEY OF THE BANK HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE
BANK WOULD NOT, IN THE EVENT OF LITIGATIONS, SEEK TO ENFORCE THE FORGOING

<PAGE>
WAIVER. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR THE BANK TO ACCEPT
THIS GUARANTY AND EXTEND CREDIT TO THE BORROWER.

EACH GUARANTOR ABSOLUTELY, UNCONDITIONALLY AND IRREVOCABLY ALSO WAIVES, TO THE
EXTENT THE GUARANTOR IS AN INDIVIDUAL, ANY CLAIM, RIGHT OR REMEDY, WHICH MAY
ARISE BY ANY STATUTE OR OTHERWISE, WHICH THE GUARANTOR MAY NOW HAVE OR HEREAFTER
ACQUIRE AGAINST THE BORROWER THAT ARISES FROM (I) THE EXECUTION OR PERFORMANCE
BY THE GUARANTOR OF ITS OBLIGATIONS TO THE BANK UNDER THIS GUARANTY, INCLUDING,
WITHOUT LIMITATION, ANY CLAIM, REMEDY OR RIGHT OF SUBROGATION, REIMBURSEMENT,
EXONERATION, CONTRIBUTION, OR INDEMNIFICATION AGAINST THE BORROWER, OR (II) THE
PARTICIPATION BY THE GUARANTOR IN ANY CLAIM, RIGHT OR REMEDY OF THE BANK AGAINST
THE BORROWER OR IN ANY SECURITY WHICH THE BANK NOW HAS OR HEREAFTER ACQUIRES BY
STATUTE, UNDER COMMON LAW OR OTHERWISE.

Each Guarantor hereby authorizes the Bank to date this Guaranty and to complete
and fill in any blank spaces in this Guaranty in order to conform to terms upon
which the Guaranty is provided. Each Guarantor further authorizes the Bank to
execute and file one or more financing statements covering the collateral
security or any part thereof and each Guarantor agrees to bear the cost of such
filing(s). Upon receipt of an affidavit of an officer of the Bank as to the
loss, theft, destruction or mutilation of this Guaranty or any other security
document which is not of public record, and, in the case of any such loss,
theft, destruction or mutilation, upon cancellation of such Guaranty or other
security document, each Guarantor will issue, in lieu thereof, a replacement
Guaranty or other security document.

The Bank shall have the unrestricted right at any time or from time to time, and
without any Guarantor's consent, to assign all or any portion of its rights and
obligations hereunder to one or more banks or other financial institutions
(each, an "Assignee"), and the Guarantor agrees that it shall execute, or cause
to be executed, such documents, including without limitation, amendments hereto
and to any other documents executed in connection herewith or pursuant hereto
(collectively the "Loan Documents") as the Bank shall deem necessary to effect
the foregoing. Upon the execution and delivery of appropriate assignment
documentation, amendments and any other documentation required by the Bank in
connection with such assignment, and the payment by Assignee of the purchase
price agreed to by the Bank, and such Assignee, such Assignee shall have all of
the rights and obligations of the Bank hereunder (and under any and all other
Loan Documents) to the extent that such rights and obligations have been
assigned by the Bank pursuant to the assignment documentation between the Bank
and such Assignee, and the Bank shall be released from its obligations hereunder
and thereunder to a corresponding extent.

<PAGE>
The Bank shall have the unrestricted right at any time and from time to time,
and without the consent of, or notice to the Borrower or to the Guarantor, to
grant one or more banks or other financial institutions (each, a "Participant")
participating interests in the Liabilities. In the event of any such grant by
the Bank of a participating interest to a Participant, whether or not upon
notice to the Borrower or the Guarantor, the Bank shall remain responsible for
the performance of its obligations under the Loan Documents and the Borrower and
the Guarantor shall continue to deal solely and directly with the Bank in
connection with the Bank's rights and obligations thereunder.

The Bank may furnish any information concerning the Guarantor in its possession
from time to time to prospective Assignees and Participant, provided that the
Bank shall require any such prospective Assignee or Participant to agree in
writing to maintain the confidentiality of such information.

(Individual Guarantor only) The Guarantor agrees that the Bank may obtain any
credit, employment and income information about the Guarantor as the Bank deems
necessary in connection with this Guaranty. The Bank may obtain a consumer
credit report reflecting the Guarantor's personal credit history at the time of
origination, modification, extension, renewal or collection of the Liabilities
or at any other time deemed appropriate by the Bank. At the Guarantor's request,
the Bank will disclose whether it has obtained a report and, if so, the name and
address of the consumer reporting agency that provided it.

The Bank may at any time pledge or assign all or any portion of its rights under
the Loan Documents to any of the twelve (12) Federal Reserve Banks organized
under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such
pledge or assignment or enforcement thereof shall release the Bank from its
obligations under any of the Loan Documents.

(CONNECTICUT ONLY) COMMERCIAL TRANSACTION. EACH GUARANTOR ACKNOWLEDGES THAT THIS
GUARANTY AND EACH TRANSACTION RELATED TO IT IS A "COMMERCIAL TRANSACTION" WITHIN
THE MEANING OF CHAPTER 903A OF THE CONNECTICUT GENERAL STATUTES, AS AMENDED.
EACH GUARANTOR HEREBY WAIVES ANY RIGHT WHICH IT MIGHT HAVE TO NOTICE AND A
HEARING OR A PRIOR COURT ORDER, UNDER SAID CHAPTER 90A OR AS OTHERWISE PROVIDED
UNDER ANY APPLICABLE FEDERAL OR STATE LAW, IN THE EVENT THE BANK SEEKS ANY
PREJUDGMENT REMEDY IN CONNECTION WITH THIS GUARANTY.

The term "Bank" as used herein shall be deemed to include the Bank and its
successors, endorsers and assigns.
