SECTION 2. REVOLVING CREDIT FACILITY.

     Section 2.1. Commitment to Lend. (a) Upon the terms and subject to the
conditions of this Agreement, Bank agrees to lend to the Borrower such sums that
the Borrower may request, from the date hereof until but not including the
Termination Date, provided that the sum of the outstanding principal amount of
all Loans (after giving effect to all amounts requested) shall not exceed the
Commitment. LIBOR Rate Loans shall be in the minimum aggregate amount of
$300,000 or whole multiples of $100,000 in addition thereto.

     (b) The Borrower shall give to Bank, written Notice in the form of Exhibit
B attached hereto of each Loan requested to be made hereunder (a "Loan Request")
(i) no later than 12:00 noon, New York time, on the proposed Drawdown Date of
any Base Rate Loan and (ii) no less than three (3) LIBOR Business Days prior to
the proposed Drawdown Date of any LIBOR Rate Loan. Each such Notice shall
specify (A) the principal amount of the Loan requested, (B) the proposed
Drawdown Date of such Loan (which must be a Business Day or a LIBOR Business
Day, as the case may be), (C) the Interest Period for such Loan and (D) whether
such Loan shall be a Base Rate Loan or a LIBOR Rate Loan. Each Loan Request
shall be irrevocable and binding on the Borrower and shall obligate the Borrower
to accept the Loan requested from Bank on the proposed Drawdown Date. Subject to
the foregoing, so long as Bank's Commitment is then in effect and the applicable
conditions set forth in Section 6.2 hereof have been met, Bank shall advance the
amount requested to the Borrower's bank account as designated on the applicable
Loan Request (or such other account as Bank may designate) in immediately
available funds not later than the close of business on such Drawdown Date.

     (c) The obligation of the Borrower to repay Bank the principal of the
respective Loans and interest accrued thereon shall be evidenced by a promissory
note (a "Note") substantially in the form of Exhibit C attached hereto, dated as
of the date hereof and completed with appropriate insertions. The Note shall be
executed and delivered by the Borrower and payable to the order of Bank, in form
and substance satisfactory to Bank, in a principal amount equal to the
Commitment.

     Section 2.1A. Conversion Options. (a) The Borrower may elect from time to
time to convert any outstanding Loan from a Base Rate Loan to a LIBOR Rate Loan
or from a LIBOR Rate Loan to a Base Rate Loan, provided that (i) with respect to
any such conversion of a LIBOR Rate Loan to a Base Rate Loan, the Borrower shall
give Bank at least three (3) Business Days prior written Notice of such
election; (ii) with respect to any such conversion of a LIBOR Rate Loan into a
Base Rate Loan, such conversion shall only be made on the last day of the
Interest Period with respect thereto; (iii) with respect to any such conversion
of a Base Rate Loan to a LIBOR Rate Loan, the Borrower shall give Bank at least
three (3) LIBOR Business Days prior written Notice of such election; and (iv) no
Loan may be converted into a LIBOR Rate Loan when any Default or Event of
Default has occurred and is continuing. On the date on which such conversion is
being made, Bank shall take such action as is necessary to transfer such Loans
to its Domestic Lending Office or its LIBOR Lending Office, as the case may be.
All or any part of the outstanding Loans may be converted as provided herein,
provided that any partial conversions shall be in an aggregate principal amount
of $300,000 or a whole multiple of $100,000 in addition thereto. Each Conversion
Request relating to the conversion of a Loan to a LIBOR Rate Loan shall be
irrevocable by the Borrower.

     (b) Any Base Rate Loan or LIBOR Rate Loan may be continued as such upon the
expiration of an Interest Period with respect thereto by compliance by the
Borrower with the Notice provisions contained in Section 2.1A(a); provided that
no LIBOR Rate Loan may be continued as such when any Default or Event of Default
has occurred and is continuing, but shall be automatically converted to a Base
Rate Loan on the last day of the first Interest Period relating thereto ending
during the continuance of any Default or Event of Default. In the event that the
Borrower fails to provide any such Notice with respect to the continuation of
any LIBOR Rate Loan as such, then such LIBOR Rate Loan shall be automatically
converted to a Base Rate Loan on the last day of the first Interest Period
relating thereto.

     (c) Any conversion to or from LIBOR Rate Loans shall be in such amounts and
be made pursuant to such elections so that, after giving effect thereto, (i) the
aggregate principal amount of all LIBOR Rate Loans having the same Interest
Period shall not be less than $300,000 or a whole multiple of $100,000 in
addition thereto.

     Section 2.2. Interest. So long as no Event of Default is continuing, each
Base Rate Loan shall bear interest for the period commencing with the Drawdown
Date thereof and ending on the last day of the Interest Period with respect
thereto at a rate per annum equal to the Base Rate and each LIBOR Rate Loan
shall bear interest for the period commencing with the Drawdown Date thereof and
ending on the last day of the Interest Period with respect thereto at a rate per
annum equal to the sum of (i) the LIBOR Rate determined for such Interest Period
plus (ii) the LIBOR Rate Margin. The Borrower promises to pay interest on each
Loan in arrears on each Interest Payment Date with respect thereto. While an
Event of Default is continuing and Bank shall have exercised its rights pursuant
to Section 8.1(2) hereof or in the case of an Event of Default under clause (h)
or (i) of Section 8.1, amounts payable under any of the Loan Documents shall
bear interest (compounded monthly and payable on demand in respect of overdue
amounts) at a rate per annum which is equal to the Base Rate plus two percent
(2%) until such amount is paid in full or (as the case may be) such Event of
Default has been cured or waived in writing by Bank (after as well as before
judgment).

     Section 2.3. Repayments and Prepayments. The Borrower hereby agrees to pay
to Bank, no later than the Maturity Date, the entire unpaid principal of and
interest on the Loans. The Borrower may elect to prepay the outstanding
principal of all or any part of any Loan, without premium or penalty, provided
that (a) any full or partial prepayment of the outstanding amount of any LIBOR
Rate Loans pursuant to this Section 2.3 may be made only on the last day of the
Interest Period relating thereto, and (b) any such prepayments of LIBOR Rate
Loans shall be in a minimum amount of $300,000 or a whole multiple of $100,000
in addition thereto. The Borrower shall give Bank Notice of the date and amount
of any proposed prepayment pursuant to this Section 2.3 (y) no less than three
(3) LIBOR Business Days prior to any such proposed prepayment of any LIBOR Rate
Loans, and (z) no later than 10:00 a.m., New York time, on the date of any such
prepayment of any Base Rate Loan. The Borrower shall be entitled to reborrow
before the Termination Date such amounts, upon the terms and subject to the
conditions of this Agreement. Each repayment or prepayment of principal of any
Loan shall be accompanied by payment of the unpaid interest accrued to such date
on the principal being repaid or prepaid and shall be applied, in the absence of
instruction by the Borrower, first to the principal of Base Rate Loans and then
to the principal of LIBOR Rate Loans. If at any time the aggregate amount of
Loans outstanding shall exceed the Commitment, the Borrower shall immediately
pay the amount of such excess to Bank for application to the Loans. The Borrower
may elect to reduce or terminate the Commitment by a minimum principal amount of
$100,000 or an integral multiple thereof of the amount reduced or, as the case
may be, terminated, upon Notice to Bank given by 10:00 a.m., New York time, at
least two (2) Business Days prior to the date of such reduction or termination.
The Borrower shall not be entitled to reinstate the respective Commitment
following such reduction or termination.

SECTION 3. INDEMNITY FOR CHANGES IN CIRCUMSTANCES, ETC.

     The Borrower agrees to indemnify Bank and to hold it harmless from and
against any loss, cost or expense (including loss of anticipated profits) that
Bank may sustain or incur as a consequence of (i) default by the Borrower in
payment of the principal amount of or any interest on any LIBOR Rate Loans as
and when due and payable, including any such loss, cost or expense arising from
interest or fees payable by Bank to lenders of funds obtained by it in order to
maintain its LIBOR Rate Loans or the cost of breaking any swaps or other hedging
agreements, (ii) default by the Borrower in making a borrowing or conversion
after the Borrower has given (or is deemed to have given) a Loan Request or
Conversion Request relating thereto in accordance with Section 2.1A, and (iii)
the making of any payment of a LIBOR Rate Loan or the making of any conversion
of any such Loan to a Base Rate Loan on a day that is not the last day of the
applicable Interest Period with respect thereto, including interest or fees
payable by Bank to lenders of funds obtained by it in order to maintain any such
Loans or the cost of breaking any swaps or other hedging agreements.

SECTION 4. FEES AND PAYMENTS.

     Section 4.1. Revolving Credit Commitment Fees. The Borrower shall pay to
Bank a commitment fee at the rate per annum equal to one-fourth of one percent
(1/4 of 1%) (computed on the basis of a year of 360 days and the actual number
of days elapsed) on the average daily


                                      -11-




<PAGE>

unused Commitment. Such commitment fee shall be payable quarter-annually in
arrears on the last Business Day of each November, February, May and August in

earlier date, in which event the commitment fee for the period to the date of
such termination in whole shall be paid on the date of such termination.

     Section 4.2. Payments. All payments to be made by the Borrower hereunder or
under any of the other Loan Documents shall be made in U.S. Dollars in

counterclaim and without any withholding or deduction whatsoever. The Bank shall
be entitled to charge any account of the Borrower with Bank for any sum due and
payable by the Borrower to Bank hereunder or under any of the other Loan
Documents. If any payment hereunder is required to be made on a day which is not
a Business Day, it shall be paid on the immediately succeeding Business Day,
with interest and any applicable fees adjusted accordingly. All computations of
interest or fees payable hereunder shall be made by Bank on the basis of actual
days elapsed and on a 360-day year.

     each Subsidiary of the Loan Documents to which it is a party (i) are within
     its corporate authority, (ii) have been duly authorized, (iii) do not

          (e) since May 31, 2004, there has been no material adverse change of
     any kind in the business or financial condition of the Borrower which would
     have a Materially Adverse Effect;

     or, to the knowledge of the Borrower, threatened against the Borrower

     any Consents (other than the Consent of Antwerp Diamond Bank in connection
     with the Antwerp Diamond Bank Line and the Consent of the agent and each of
     the lenders under the ABN AMBRO LEUMI Credit Agreement), to the Borrower
     borrowing up to $30,000,000 from time to time from Bank on an unsecured
     basis, guaranteed by such Subsidiaries of the Borrower as Bank may require;

     contingent liabilities with respect to any post-retirement benefits under a
     welfare plan, as defined in Section 3(i) of ERISA, other than liability for
     continuation coverage described in article 6 of Title 1 of ERISA;

     real property, including leaseholds, owned or operated by the Borrower or
     any of its Subsidiaries; there are no facts, circumstances, conditions or
     occurrences on any real property, including leaseholds, owned or operated

     the Borrower and its Subsidiaries after due inquiry, could reasonably be
     expected (i) to form the basis of an Environmental Claim against the
     Borrower or any of its Subsidiaries or any such real property, or (ii) to
     cause any such real property to be subject to any restrictions on the
     ownership, occupancy, use or transferability of such real property by the
     Borrower or any of its Subsidiaries under any applicable Environmental Law;
     Hazardous Materials have not been Released on or from any real property,
     including leaseholds, owned or operated by the Borrower or any of its
     Subsidiaries where such


                                      -14-




<PAGE>

     Release, individually, may reasonably be expected to require in excess of

     instruments or documents as shall be reasonably satisfactory to Bank, upon
     satisfaction of which, such contribution shall be considered an addition to
     Net Income for the period tested), in an amount which, after giving effect
     thereto, would enable the Borrower to meet the requirements as in effect on
     the Compliance Date of the covenants of Section 7.3 giving rise to the

     aggregate;

     THEN, or at any time thereafter:

          (1) In the case of any Event of Default under clause (h) or (i), (A)
     the Commitment shall automatically terminate and Bank shall be relieved of
     all further obligations, as provided herein, to make Loans to the Borrower,

     accrued and unpaid thereon, all accrued and unpaid fees, and all other
     amounts payable hereunder and under the other Loan Documents shall

at any time without Notice to the Borrower, or compliance with any other
procedure imposed by statute or otherwise, all of which are hereby expressly
waived by the Borrower. The Bank agrees to notify the Borrower promptly after
such setoff.

SECTION 10. CHANGE IN CIRCUMSTANCES.

     Section 10.1. Change of Law. Notwithstanding any other provisions of this
Agreement or the Note, if at any time any change in applicable law or regulation
or in the interpretation thereof makes it unlawful for Bank to make or continue
to maintain any LIBOR Rate Loans or to perform its obligations as contemplated
hereby, Bank shall promptly give notice thereof to the Borrower and Bank's
obligations to make or maintain LIBOR Rate Loans under this Agreement shall be
suspended until it is no longer unlawful for it to make or maintain LIBOR Rate
Loans. The Borrower shall prepay on demand the outstanding principal amount of
any such affected LIBOR Rate Loans, together with all interest accrued thereon
and all other amounts then due and payable to Bank under this Agreement;
provided, however, subject to all of the terms and conditions of this Agreement,
the Borrower may then elect to borrow the principal amount of the affected LIBOR
Rate Loans from Bank by means of Base Rate Loans from Bank.

     Section 10.2. Unavailability of Deposits or Inability to Ascertain, or
Inadequacy of, LIBOR. If on or prior to the first day of any Interest Period for
any Borrowing of LIBOR Rate Loans:

          (a) Bank determines that deposits in U.S. Dollars (in the applicable
     amounts) are not being offered to it in the interbank eurodollar market for
     such Interest Period, or that by reason of circumstances affecting the
     interbank eurodollar market adequate and reasonable means do not exist for
     ascertaining the applicable LIBOR, or

          (b) Bank determines that the making or funding of LIBOR Rate Loans
     become impracticable,

then Bank shall forthwith give notice thereof to the Borrower, whereupon until
Bank notifies the Borrower that the circumstances giving rise to such suspension
no longer exist, the obligations of Bank to make LIBOR Rate Loans shall be
suspended.

     Section 10.3. Increased Cost and Reduced Return. (a) If, on or after the
date hereof, the adoption of any applicable law, rule or regulation, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by Bank (or its Lending
Office) with any request or directive (whether or not having the force of law)
of any such authority, central bank or comparable agency:

               (i) shall subject Bank (or its Lending Office) to any tax, duty
          or other charge with respect to its LIBOR Rate Loans or the Note or
          its obligation to make LIBOR Rate Loans or shall change the basis of
          taxation of payments to Bank (or its Lending Office) of the principal
          of or interest on its LIBOR Rate Loans or any other amounts due under
          this Agreement or any other Loan Document in respect of its LIBOR Rate
          Loans, or its obligation to make LIBOR Rate Loans (except for changes
          in the rate of tax on the overall net income of Bank or its Lending
          Office imposed by the jurisdiction in which Bank's principal executive
          office or Lending Office is located); or


                                      -22-




<PAGE>

               (ii) shall impose, modify or deem applicable any reserve, special
          deposit or similar requirement (including, without limitation, any
          such requirement imposed by the Board of Governors of the Federal
          Reserve System, but excluding with respect to any LIBOR Rate Loans any
          such requirement included in an applicable Eurocurrency Reserve Rate)
          against assets of, deposits with or for the account of, or credit
          extended by, Bank (or its Lending Office) or shall impose on Bank (or
          its Lending Office) or on the interbank market any other condition
          affecting its LIBOR Rate Loans or the Note, or its obligation to make
          LIBOR Rate Loans;

and the result of any of the foregoing is to increase the cost to Bank (or its
Lending Office) of making or maintaining any LIBOR Rate Loan or to reduce the
amount of any sum received or receivable by Bank (or its Lending Office) under
this Agreement or under any other Loan Document with respect thereto, by an
amount deemed by Bank to be material, then, within 30 days after demand by Bank,
the Borrower shall be obligated to pay to Bank such additional amount or amounts
as will compensate Bank for such increased cost or reduction.

          (b) If, after the date hereof, Bank shall have determined that the
     adoption of any applicable law, rule or regulation regarding capital
     adequacy, or any change therein, or any change in the interpretation or
     administration thereof by any governmental authority, central bank or
     comparable agency charged with the interpretation or administration
     thereof, or compliance by Bank (or its Lending Office) with any request or
     directive regarding capital adequacy (whether or not having the force of
     law) of any such authority, central bank or comparable agency, has had the
     effect of reducing the rate of return on Bank's capital as a consequence of
     its obligations hereunder to a level below that which Bank could have
     achieved but for such adoption, change or compliance (taking into
     consideration Bank's policies with respect to capital adequacy) by an
     amount deemed by Bank to be material, then from time to time, within 30
     days after demand by Bank, the Borrower shall pay to Bank such additional
     amount or amounts as will compensate Bank for such reduction.

          (c) A certificate of Bank claiming compensation under this Section
     10.3 and setting forth the additional amount or amounts to be paid to it
     hereunder shall be conclusive if reasonably determined. In determining such
     amount, Bank may use any reasonable averaging and attribution methods.

     Section 10.4. Lending Offices. The Bank may, at its option, elect to make
its Loans hereunder at the branch, office or affiliate specified on the
appropriate signature page hereof (each a "Lending Office") for each type of
Loan available hereunder or at such other of its branches, offices or affiliates
as it may from time to time elect and designate in a Notice to the Borrower.

     Section 10.5. Discretion of Bank as to Manner of Funding. Notwithstanding
any other provision of this Agreement, Bank shall be entitled to fund and
maintain its funding of all or any part of the Loans in any manner it sees fit,
it being understood, however, that for the purposes of this Agreement all
determinations hereunder with respect to LIBOR Rate Loans shall be made as


                                      -23-




<PAGE>

if Bank had actually funded and maintained each LIBOR Rate Loan through the
purchase of deposits in the interbank eurodollar market having a maturity
corresponding to such Loan's Interest Period and bearing an interest rate equal
to LIBOR for such Interest Period.

harmless Bank and its respective affiliates (the "Indemnified Parties") from and

and which arise by reason of the transactions contemplated hereby or by any of
the Loan Documents, in each case including, without limitation, the reasonable

negligence or willful misconduct of the Indemnified Party, or (ii) any breaches
by the Indemnified Party of its obligations under this Agreement or any of the
Loan Documents. In litigation, or the preparation therefor, Bank and its
respective affiliates shall be entitled to select its own counsel reasonably

damages other than, or in addition to, actual damages. The Borrower (i)
certifies that Bank has not and that no representative, or attorney of Bank has,
represented, expressly or otherwise, that Bank would not, in the event of
litigation, seek to enforce the foregoing waivers and (ii) acknowledges that
Bank has been induced to enter into this Agreement, the other Loan Documents to
which it is a party by, among other things, the waivers and certifications
contained herein.

SECTION 20. CONSENTS, AMENDMENTS, WAIVERS, ETC.

     Any Consent or approval required or permitted by this Agreement to be given
by Bank may be given, and any term of this Agreement, the other Loan Documents
or any other instrument related hereto or mentioned herein may be amended, and
the performance or observance by the Borrower or any of its Subsidiaries of any
terms of this Agreement, the other Loan Documents or such other instrument or
the continuance of any Default or Event of Default may be waived (either
generally or in a particular instance and the retroactively or prospectively)
with, but only with, the written Consent of the Borrower and the written Consent
of Bank. No course of dealing or delay or omission on the part of Bank in
exercising any right shall operate as a waiver thereof or otherwise be
prejudicial thereto. No Notice to or demand upon the Borrower shall entitle the
Borrower to other or further Notice or demand in similar or other circumstances.

SECTION 21. SEVERABILITY.

     The provisions of this Agreement are severable and if any one clause or
provision hereof shall be held invalid or unenforceable in whole or in part in
any jurisdiction, then such invalidity or unenforceability shall affect only
such clause or provision, or part thereof, in such jurisdiction, and shall not
in any manner affect such clause or provision in any other jurisdiction, or any
other clause or provision of this Agreement in any jurisdiction.

SECTION 22. EXTENSION OF TERMINATION DATE.

     The Borrower may annually request that the Commitment be extended for an
additional one-year period by providing notice of such request to Bank no later
than 60 days prior to November 30 of each year, commencing November 30, 2005. If
Bank agrees to extend its Commitment, it will notify the Borrower, in writing,
of its decision to do so on or before the October 31 following such request and
Bank's Commitment will be extended for an additional one-year period from the
then existing Termination Date. If Bank declines the Borrower's request for a

                                    Exhibit A
                                    GUARANTY

     This Guaranty Agreement (the "Guaranty") dated as of this ____ day of
September, 2004, from each of the parties who have executed this Guaranty (being
herein referred to collectively, as the "Guarantors" and individually, as a
"Guarantor") in favor of HSBC BANK USA, NATIONAL ASSOCIATION ("Bank").

                                WITNESSETH THAT:

     WHEREAS, Lazare Kaplan International Inc., a Delaware corporation,
(the"Borrower") and Bank have entered into the Revolving Credit Agreement, dated
as of September __, 2004 (such Revolving Credit Agreement as the same may be
amended, modified, supplemented, restated and/or replaced from time to time
being hereinafter referred to as the "Bank Credit Agreement"), pursuant to which
Bank has agreed, subject to certain terms and conditions, to extend credit and
make certain other financial accommodations to the Borrower;

     WHEREAS, Bank shall be hereinafter referred to as the "Guaranteed
Creditor";

     WHEREAS, pursuant to the Bank Credit Agreement, Bank has required, among
other things, that each Guarantor provide to the Guaranteed Creditor its payment
guarantee of the credit facilities under the Bank Credit Agreement;

     WHEREAS, the Borrower provides each Guarantor that is a subsidiary of the
Borrower (whether directly or indirectly) with substantial financial,
management, administrative, and technical support, and each Guarantor will
benefit, directly or indirectly, from credit and other financial accommodations
extended by the Guaranteed Creditor to the Borrower;

     WHEREAS, as to each Guarantor that is not a subsidiary of the Borrower, it
is in the best business interest of such Guarantor and its stockholders that the
Borrower receive credit and other financial accommodations extended by the
Guaranteed Creditor because of the mutual business interests and endeavors of
the Borrower and such Guarantor;

     NOW, THEREFORE, for and in consideration of the benefits accruing to each
Guarantor, the receipt and sufficiency are hereby acknowledged, each Guarantor
hereby makes the following representations and warranties to the Guaranteed
Creditor and hereby covenants and agrees with the Guaranteed Creditor as
follows:

     Section 1. All capitalized terms used herein without definition shall have
the same meanings herein as such terms have in the Bank Credit Agreement.

     Section 2. Each Guarantor hereby jointly and severally guarantees to the
Guaranteed Creditor, the due and punctual payment when due of (a) any and all
indebtedness, obligations, and liabilities of whatsoever kind and nature of the
Borrower under the Bank Credit Agreement and the Note (whether arising before or
after the filing of a petition in bankruptcy), whether direct or indirect,
absolute or contingent, due or to become due, and whether now existing or


                                       -1-




<PAGE>

hereafter arising and howsoever held, evidenced, or acquired, and whether
several, joint, or joint and several (the "Bank Obligations"), (b) any and all
reasonable expenses and charges, legal or otherwise, suffered or incurred by the
Guaranteed Creditor, in collecting or enforcing any of such indebtedness,
obligations, or liabilities or in realizing on or protecting or preserving any
security therefor, if any (all of the foregoing being hereinafter referred to as
the "Guaranteed Indebtedness"). In case of failure by the Borrower to punctually
pay any Guaranteed Indebtedness, each Guarantor hereby jointly and severally
agrees to make such payment or to cause such payment to be made punctually as
and when the same shall become due and payable, whether at stated maturity, by
acceleration or otherwise. All payments hereunder by any Guarantor shall be made
in immediately available and freely transferable funds in Dollars without
set-off, counterclaim or other defense or withholding or deduction of any
nature. Notwithstanding anything in this Guaranty to the contrary, the right of
recovery against a Guarantor under this Guaranty shall not exceed $1.00 less
than the amount which would render such Guarantor's obligations under this
Guaranty void or voidable under applicable law, including fraudulent conveyance
law.

     Section 3. Each Guarantor further jointly and severally agrees to pay on
demand all reasonable out of pocket expenses, legal and/or otherwise (including
court costs and reasonable attorneys' fees), paid or incurred by the Guaranteed
Creditor in endeavoring to collect the Guaranteed Indebtedness or any part
thereof, or in enforcing or endeavoring to enforce any Guarantor's obligations
hereunder, or any part thereof, or in protecting, defending or enforcing this
Guaranty in any litigation, bankruptcy or insolvency proceedings or otherwise.

     Section 4. Each Guarantor agrees that, upon demand, such Guarantor shall
pay to the Guaranteed Creditor the full amount of the indebtedness hereby
guaranteed then due (subject to the right of recovery from such Guarantor
pursuant to the last sentence of Section 2 above) whether or not any one or more
of the other Guarantors shall then or thereafter pay any amount whatsoever in
respect to their obligations hereunder, provided, however, that the aggregate
amount payable by the Guarantors shall in no event exceed the amount due and
owing to the Guaranteed Creditor by the Borrower, plus any amounts payable under
Section 3 above.

     Section 5. Each Guarantor agrees that such Guarantor will not exercise or
enforce any right of exoneration, contribution, reimbursement, recourse or
subrogation available to such Guarantor against any Person liable for payment of
the indebtedness hereby guaranteed, or as to any security therefor, unless and
until the full amount owing and payable to the Guaranteed Creditor of the
Guaranteed Indebtedness has been fully paid and satisfied and the commitment by
the Guaranteed Creditor to extend any Guaranteed Indebtedness shall have expired
or otherwise terminated. The payment by any Guarantor of any amount or amounts
to the Guaranteed Creditor pursuant hereto shall not in any way entitle any such
Guarantor, either at law, in equity or otherwise, to any right, title or
interest (whether by way of subrogation or otherwise) in and to the Guaranteed
Indebtedness or any part thereof or any collateral security therefor, if any, or
any other rights or remedies in any way relating thereto or in and to any
amounts theretofore, then or thereafter paid or applicable to the payment
thereof howsoever such payment may be made and from whatsoever source such
payment may be derived unless and until all of the Guaranteed Indebtedness and
all costs and expenses suffered or incurred by the Guaranteed Creditor in
enforcing this Guaranty have been paid and satisfied in full and each of the
commitments by the


                                       -2-




<PAGE>

Guaranteed Creditor to extend any Guaranteed Indebtedness shall have expired or
otherwise terminated and unless and until such payment in full and termination,
any payments made by any Guarantor hereunder and any other payments from
whatsoever source derived on account of or applicable to the Guaranteed
Indebtedness or any part thereof shall be held and taken to be merely payments
to the Guaranteed Creditor reducing pro tanto the indebtedness hereby
guaranteed.

     Section 6. This Guaranty is a continuing, absolute and unconditional
guaranty of payment and not merely of collection, and shall remain in full force
and effect as against each Guarantor until all of the Guaranteed Indebtedness
shall be fully paid and satisfied and the commitment by the Guaranteed Creditor
to extend any Guaranteed Indebtedness shall have expired or have been
terminated. The Guaranteed Creditor may at any time or from time to time release
any Guarantor from its obligations hereunder or effect any compromise with any
Guarantor and no such release or compromise shall in any manner impair or
otherwise affect the obligations hereunder of the other Guarantors. No release,
compromise, or discharge of any one or more of the Guarantors shall release,
compromise or discharge the obligations of the other Guarantors hereunder.

     Section 7. In case of the dissolution, liquidation or insolvency (howsoever
evidenced) of, or the institution of voluntary bankruptcy or receivership
proceedings against the Borrower or the institution of involuntary bankruptcy
proceedings against the Borrower that are not dismissed within sixty (60) days
following the commencement thereto, all of the Guaranteed Indebtedness relating
to the Borrower which is then existing shall immediately become due or accrued
and payable from the Guarantors. All payments received from the Borrower or on
account of the Guaranteed Indebtedness from whatsoever source, shall be taken
and applied as payment on the indebtedness hereby guaranteed, and this Guaranty
shall apply to and secure any ultimate balance that shall remain owing to the
Guaranteed Creditors.

     Section 8. The liability hereunder shall in no way be affected or impaired
by (and the Guaranteed Creditor is hereby expressly authorized to make from time
to time, without notice to any of the Guarantors), any sale, pledge, surrender,
compromise, settlement, release, renewal, extension, impairment, indulgence,
alteration, substitution, exchange, change in, modification or other disposition
of any of the Guaranteed Indebtedness, either express or implied, or of any Loan
Document or any other contract or contracts evidencing any thereof, or of any
security or collateral therefor or any guaranty thereof. The liability hereunder
shall in no way be affected or impaired by any acceptance or release by the
Guaranteed Creditor of any security for or other guarantors upon any of the
Guaranteed Indebtedness, or by any failure, neglect or omission on the part of
the Guaranteed Creditor to realize upon or protect any of the Guaranteed
Indebtedness, or any collateral or security therefor, if any, (including,
without limitation, impairment of collateral and failure to perfect security
interest in any collateral), or to exercise any lien upon or right of
appropriation of any moneys, credits or property of the Borrower or any
Guarantor, possessed by the Guaranteed Creditor, toward the liquidation of the
Guaranteed Indebtedness, or by any application of payments or credits thereon.
In order to hold any Guarantor liable hereunder, there shall be no obligation on
the part of the Guaranteed Creditor, at any time, to resort for payment to the
Borrower or to any other Guarantor, or to any other Person, its property or
estate, or resort to any collateral, security, property, liens or other rights
or


                                       -3-




<PAGE>

remedies whatsoever, and the Guaranteed Creditor shall have the right to enforce
this Guaranty against any Guarantor irrespective of whether or not other
proceedings or steps are pending seeking resort to or realization upon or from
any of the foregoing are pending.

     Section 9. All diligence in collection or protection, and all presentment,
demand, protest and/or notice, as to any and everyone, whether or not the
Borrower or the Guarantors or others, of dishonor and of default and of
non-payment and of the creation and existence of any and all of said Guaranteed
Indebtedness, and of any security and collateral therefor, and of the acceptance
of this Guaranty, and of any and all extensions of credit and indulgence
hereunder, are expressly waived.

     Section 10. The Guarantors waive any and all defenses, claims and
discharges of the Borrower, or any other obligor or guarantor, pertaining to the
Guaranteed Indebtedness, except the defense of discharge by irrevocable payment
in full. Without limiting the generality of the foregoing, the Guarantors will
not assert, plead or enforce against the Guaranteed Creditor any defense of
waiver, release, discharge in bankruptcy, statute of limitations, res judicata,
statute of frauds, anti-deficiency statute, fraud, incapacity, minority, usury,
illegality or unenforceability which may be available to the Borrower or any
other Person liable in respect of any of the Guaranteed Indebtedness, or any
set-off available against the Guaranteed Creditor to the Borrower or any such
other Person, whether or not on account of a related transaction. The Guarantors
agree that the Guarantors shall be and remain jointly and severally liable for
any deficiency remaining after foreclosure or other realization on any lien or
security interest, if any, securing the Guaranteed Indebtedness, whether or not
the liability of the Borrower or any other obligor for such deficiency is
discharged pursuant to statute or judicial decision.

     Section 11. If any payment applied by the Guaranteed Creditor to the
indebtedness hereby guaranteed is thereafter set aside, recovered, rescinded or
required to be returned for any reason (including, without limitation, the
bankruptcy, insolvency or reorganization of the Borrower or any other obligor),
the Guaranteed Indebtedness to which such payment was applied shall for the
purposes of this Guaranty be deemed to have continued in existence,
notwithstanding such application, and this Guaranty shall be enforceable as to
such of the Guaranteed Indebtedness as fully as if such application had never
been made.

     Section 12. The liability of the Guarantors under this Guaranty is in
addition to and shall be cumulative with all other liabilities of the Guarantors
after the date hereof to the Guaranteed Creditor as a guarantor of the
indebtedness hereby guaranteed, without any limitation as to amount, unless the
instrument or agreement evidencing or creating such other liability specifically
provides to the contrary.

     Section 13. Any invalidity or unenforceability of any provision or
application of this Guaranty shall not affect other lawful provisions and
applications hereof, and to this end the provisions of this Guaranty are
declared to be severable. Without limiting the generality of the foregoing, any
invalidity or unenforceability against any Guarantor of any provision or
application of the Guaranty shall not affect the validity or enforceability of
the provisions or application of this Guaranty as against the other Guarantors.


                                       -4-

     Section 14. Any demand for payment on this Guaranty or any other notice
required or desired to be given hereunder to any Guarantor shall be in writing
(including, without limitation, notice by telecopy) and shall be given to the
relevant party at its address or telecopier number set forth on the appropriate
signature page hereof, or such other address or telecopier number as such party
may hereafter specify by notice to Bank given by United States certified or
registered mail or by telecopy. Each such notice, request or other communication
shall be effective (i) if given by telecopier, when such telecopy is transmitted
to the telecopier number specified in this Section and a confirmation of such
telecopy has been received by the sender, or (ii) if given by mail, 5 days after
such communication is deposited in the mail, certified or registered with return
receipt requested, addressed as aforesaid.

     Section 15. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED ACCORDING TO
THE LAW OF THE STATE OF NEW YORK (without regard to principles of conflicts of
laws) in which state it shall be performed by the Guarantors and may not be
waived, amended, released or otherwise changed except by a writing signed by
Bank. This Guaranty and every part thereof shall be effective upon delivery to
the Guaranteed Creditor, without further act, condition or acceptance by the
Guaranteed Creditor, shall be binding upon the Guarantors and upon the legal
representatives, successors and assigns of the Guarantors, and shall inure to
the benefit of the Guaranteed Creditor, their successors, legal representatives
and assigns. The Guarantors waive notice of the Guaranteed Creditor's acceptance
hereof. This Guaranty may be executed in counterparts and by different parties
hereto on separate counterparts each of which shall be an original, but all
together to be one and the same instrument.

     Section 20. Each Guarantor hereby submits to the nonexclusive jurisdiction
of the United States District Court for the Southern District of New York and of
any State court sitting in New York City, for purposes of all legal proceedings
arising out of or relating to this Guaranty or the transactions contemplated
hereby. Each Guarantor irrevocably waives, to the fullest extent permitted by
law, any objection which it may now or hereafter have to the laying of the venue
of any such proceeding brought in such a court and any claim that any such
proceeding brought in such court has been brought in an inconvenient forum. EACH
GUARANTOR AND, BY ACCEPTING THE BENEFITS OF THIS AGREEMENT, THE GUARANTEED
CREDITOR HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY
LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS GUARANTY OR THE TRANSACTIONS
CONTEMPLATED HEREBY.
