Commitments hereunder as provided in Section 3.1. Not later than 3:00 p.m. New
York City time on the date of such borrowing, each Bank shall, through its
Lending Office and subject to the conditions of this Agreement, make the amount
of the Revolving Credit Loan to be made by it on such date available to the
Borrower, in immediately available funds, by crediting an account of the
Borrower designated by the Borrower and maintained with such Bank.

            (b) In the case of each Revolving Credit Loan which is a LIBOR Loan,
the Borrower shall select an Interest Period of any duration in accordance with
the definition of Interest Period in Section 1. 1, subject to the limitations
that no Interest Period for a LIBOR Loan shall have a duration less that one
month, and if any such proposed Interest Period would otherwise be for a shorter
period, such Interest Period shall not be available.

            (c) Upon the expiration of an Interest Period for any Revolving
Credit Loan, or any portion thereof, such Revolving Credit Loan or portion
thereof shall be automatically continued as a Prime Rate Loan except to the
extent that such Loan shall be repaid hereunder or unless the Borrower shall
have notified the Bank, as provided in Section 3.1 hereof, of its intention to
select a different interest rate option with respect to such Revolving Credit
Loan or any portion thereof. Subject to the following conditions and to the
terms and conditions of this Agreement, the Borrower shall have the right to
convert any Revolving Credit Loan or portion thereof to a different type of Loan
(i.e., from a Prime Rate Loan to a LIBOR Loan or vice versa):

                (i) if less than all Revolving Credit Loans at the time
outstanding shall be converted, the notice given by the Borrower to the Banks
shall specify the aggregate amount of Revolving Credit Loans in each case to be
converted and such conversion shall be made ratably among the Banks in
accordance with their respective Commitment Proportions;

                (ii) in the case of a conversion of less than all outstanding
Revolving Credit Loans, the aggregate principal amount of Revolving Credit Loans
to be converted shall not be less than (1) $1,250,000 (and if greater in
integral multiples of $100,000) in the case of conversions to or into LIBOR
Loans or (2) $250,000 (and if greater in integral multiples of $50,000) in the
case of conversions to or into Prime Rate Loans;


                                       19


                (iii) no Revolving Credit Loan may be converted to a LIBOR Loan
less than one month before the Revolving Credit Termination Date;

                (iv)  a LIBOR Loan may be converted to a different type of Loan
only on the last day of the then applicable Interest Period with respect
thereto; and

                (v) no Revolving Credit Loan or portion thereof may be converted
to a LIBOR Loan during the occurrence and continuance of an Event of Default.

            Notwithstanding anything to the contrary herein, after giving effect
to any Revolving Credit Loan, unless consented to by the Banks in their sole
discretion, there shall not be more than four (4) different Interest Periods in
effect in respect of all Revolving Credit Loans then outstanding.

            Section 2.5. Minimum Amounts of Revolving Credit Loan. Except for
                         ----------------------------------------
borrowings which involve or utilize the full remaining amount of the Revolving
Credit Commitments and payments which result in the prepayment of all Prime Rate
Loans, each borrowing and payment of a Prime Rate Loan shall be in an amount at
least equal to $250,000 and, if greater, integral multiples of $50,000 in excess
thereof. Each borrowing and payment of a LIBOR Loan shall be in an amount at
least equal to $1,250,000 and, if greater, in integral multiples of $ 100,000 in
excess thereof.

            Section 2.6.  Letters of Credit.
                          -----------------

            (a) Letters of Credit - Generally. Subject to the terms and
                -----------------------------
conditions set forth in this Agreement, upon written request of the Borrower to
the Banks in accordance herewith, provided that no Default or Event of Default
shall be existing, the Administrator shall issue Letters of Credit with pro rata
                                                                        --- ----
participation by all of the Banks in accordance with their respective Commitment
Proportions, at any time between the date hereof and the Revolving Credit
Termination Date. Notwithstanding the foregoing, at no time shall Aggregate
Letters of Credit Outstandings exceed $5,000,000 and no Letter of Credit shall
be issued or created if after giving effect to such issuance the foregoing limit
would be exceeded or the Aggregate Outstandings would exceed the Total Revolving
Credit Commitments in effect on such date. Furthermore, notwithstanding anything
contained herein to the contrary, neither the Administrator nor any of the Banks
shall be under any obligation to issue a Letter of Credit if any order, judgment
or decree of any court, arbitrator or governmental authority shall purport by
its terms to enjoin, restrict or restrain the Administrator or any of the Banks
in any respect relating to the issuance of such Letter of Credit or a similar
letter of credit, or any law, rule, regulation, policy, guideline or directive
(whether or not having the force of law) from any governmental authority with
jurisdiction over the Administrator or any of the Banks shall prohibit or direct
the Administrator or any of the Banks in any respect relating to the issuance of
such Letter of Credit or a similar letter of credit, or shall impose upon the
Administrator or any of the Banks with respect to any Letter of Credit, any
restrictions, any reserve or capital requirement or any loss, cost or expense
not reimbursed by the Borrower to the Administrator or


                                       20


any of the Banks. The Existing Letter of Credit shall automatically be deemed to
have been issued under, and shall be subject to the provisions of, this
Agreement as of the date hereof. Each request for issuance of a Letter of Credit
shall be in writing and shall be received by the Administrator by no later than
12:00 p.m., New York City time, on the day which is at least two Banking Days
prior to the proposed date of issuance. Such issuance shall occur by no later
than 5:00 p.m., New York City time, on the proposed date of issuance (assuming
proper prior notice as aforesaid). Subject to the terms and conditions contained
herein, the expiration dates, amounts and beneficiaries of the Letters of Credit
will be as designated by the Borrower. The Administrator shall promptly notify
the Banks of the amounts of all Letters of Credit issued hereunder and of any
extension, reduction, termination or amendment of any Letter of Credit. Each
Letter of Credit issued by the Administrator hereunder shall identify: (i) the
dates of issuance and expiration of such Letter of Credit, (ii) the amount of
such Letter of Credit (which shall be a sum certain), (iii) the beneficiary and
account party of such Letter of Credit, and (iv) the drafts and other documents
necessary to be presented to the Administrator upon drawing thereunder. No
Letter of Credit shall expire more than one year after its issuance, and in no
event shall any Letter of Credit expire after the Banking Day which is
immediately prior to the Revolving Credit Termination Date. The Borrower agrees
to execute and deliver to the Administrator such further documents and
instruments in connection with any Letter of Credit issued hereunder as the
Administrator in accordance with its customary practices may request.

            (b) Drawings Under Letters of Credit. The Borrower hereby absolutely
                --------------------------------
and unconditionally promises to (a) pay the Administrator as soon as possible
but in any event within one Banking Day after any drawing under a Letter of
Credit, in immediately available funds, the amount of such drawing under such
Letter of Credit, plus interest thereon from the date of such drawing until
repaid in full, or (b), by 11:00 a.m., New York City time, on the Banking Day
immediately following the day of any such drawing, request a Prime Rate Loan in
accordance with Section 2.4 hereof. The Borrower shall pay to the Administrator
interest on any amounts with respect to any such Letters of Credit not paid when
due (i.e., the amount of any drawing which is not paid or converted to a Prime
Rate Loan within one Banking Day after any such drawing pursuant to the
provisions of this Agreement) until paid at a rate per annum equal to the
Default Rate which would be applicable to a Prime Rate Loan in an amount equal
to such past due amount. If the Borrower so requests in accordance with the
terms hereof and if each of the conditions precedent to the making of a Loan set
forth in Article 5 of this Agreement has been satisfied on the Banking Day
following a drawing under a Letter of Credit, the amount of such drawing, plus
interest thereon, for which the Administrator has not been reimbursed by the
Borrower shall become a Prime Rate Loan made by the Banks to the Borrower on
such day as the Administrator shall give written notice (which written notice
shall be by facsimile transmission or telex) to the Borrower and the Banks of
such circumstances. The Administrator agrees to forward notice of the amount of
each drawing under a Letter of Credit promptly upon the occurrence thereof. Each
Bank agrees that on the first Banking Day after any such drawing, unless such
Bank has theretofore made a Prime Rate Loan in respect of such drawing, such
Bank will immediately make available by no later than 3:00 p.m. to the
Administrator at its office located at 175 Water Street, 3rd Floor, New York,
New York 10038, in Federal or other immediately available funds, its ratable
share (i.e., payment for the participation it has purchased in accordance with
its respective Commitment Proportion pursuant to Section 2.6(d)) of any such


                                       21


drawing or payment or maturity, plus any interest which shall have accrued
thereon, provided that each Bank's obligation shall be reduced by its pro rata
share (i.e., in accordance with such participation) of any reimbursement by the
Borrower in respect of any such drawing or payment pursuant to this Section.

                (c)   Letter of Credit Obligations Absolute.
                      --------------------------------------

                      (i) The obligation of the Borrower to reimburse the 
Administrator as provided hereunder in respect of drawings or payments under
Letters of Credit shall rank pari passu with the obligation of the Borrower to
repay the Loans hereunder, shall be absolute and unconditional under any and all
circumstances and shall be secured pro rata with the other Obligations (if any)
pursuant to the Security Agreements, the Pledge Agreement and the Patent and
Trademark Security Agreement. Without limiting the generality of the foregoing,
the obligation of the Borrower to reimburse the Administrator in respect of
drawings under Letters of Credit shall not be subject to any defense based on
the non-application or misapplication by the beneficiary of the proceeds of any
such payment or the legality, validity, regularity or enforceability of the
Letters of Credit or any related document or any dispute between or among the
Borrower, the beneficiary of any Letter of Credit or any financing institution
or other party to which any Letter of Credit may be transferred. The
Administrator may pay any draft presented to it under any Letter of Credit
regardless of when drawn or made and whether or not negotiated, if such draft,
accompanying certificate or documents and any transmittal advice are presented
or negotiated on or before the expire date of the Letter of Credit or any
renewal or extension thereof then in effect, and conforms to the terms and
conditions of such Letter of Credit. Furthermore, neither the Administrator nor
any of its correspondents shall be responsible, as to any document presented
under a Letter of Credit which appears to be regular on its face, and appears on
its face to conform to the terms of the Letter of Credit, for the validity or
sufficiency of any signature or endorsement, for delay in giving any notice or
failure of any instrument to bear adequate reference to the Letter of Credit, or
for failure of any person to note the amount of any draft on the reverse of the
Letter of Credit.

                      (ii) Any action, inaction or omission on the part of the
Administrator or any of its correspondents under or in connection with any
Letter of Credit or the related instruments, documents or property, if in good
faith and in conformity with such laws, regulations or customs as are
applicable, shall be binding upon the Borrower and shall not place the
Administrator or any of its correspondents under any liability to the Borrower,
in the absence of (i) gross negligence or willful misconduct by the
Administrator or its correspondents or (ii) the failure by the Administrator to
pay under a Letter of Credit after presentation of a draft and documents
strictly complying with such Letter of Credit. The Administrator's rights,
powers, privileges and immunities specified in or arising under this Agreement
are in addition to any heretofore or at any time hereafter otherwise created or
arising, whether by statute or rule of law or contract. All Letters of Credit
issued hereunder will, except to the extent otherwise expressly provided
hereunder, be governed by the Uniform Customs and Practice for Documentary
Credits (1993 Revision), International Chamber of Commerce, Publication No. 500,
and any subsequent revisions thereof.


                                       22




                        (d) Participations of Banks in Respect of Letters of
                            ------------------------------------------------
Credit. The Administrator and each Bank hereby irrevocably agree that the
- - ------
Administrator shall grant and hereby grants to each Bank, and each Bank shall
accept and purchase and hereby accepts and purchases from the Administrator, an
undivided risk participation in each Letter of Credit issued by the
Administrator pursuant to this Agreement equal to such Bank's Commitment
Proportion of the Administrator's rights and obligations under such Letter of
Credit. Each Bank agrees with the Administrator and the other Banks that its
obligation to make the payments required by subsection (b) hereof relating to
any such participations shall not be affected in any way by any circumstances
(other than the gross negligence or willful misconduct of the Administrator)
occurring before or after the making of any payment by the Administrator
pursuant to any Letter of Credit, including, without limitation:

            (i) any modification or amendment of, or any consent, waiver,
release or forbearance with respect to, any of the terms of this Agreement or
any other instrument or document referred to herein;

            (ii) the existence of any Default or Event of Default; or

            (iii) any change of any kind whatsoever in the financial position or
credit worthiness of the Borrower. Whenever the Administrator has received from
any Bank the payment in respect of its participation in any Letter of Credit
required of such Bank under Section 2.6(b) hereof and it thereafter receives any
payment related to such Letter of Credit (whether directly from the Borrower or
any Guarantor or otherwise, including proceeds of Collateral), the Administrator
will promptly distribute to such Bank its pro rata share thereof (provided,
however, that if the Administrator shall thereafter be required to return any
such payment so received, such Bank shall in turn return to the Administrator
the portion of such payment so distributed by the Administrator to it).

       (e) Use of Proceeds. The Borrower shall utilize Letters of Credit
           ---------------
hereunder for general corporate purposes only. No part of the proceeds of any
Letter of Credit will be used for any purpose which violates the provisions of
Regulation G, T, U or X of the Board of Governors of the Federal Reserve System
as in effect on the date of issuance, drawing, creation or maturity with respect
to any such Letter of Credit.

       (f) Existing Letter of Credit. The Borrower and the Banks hereby agree
           -------------------------
that from and after the date hereof, subject to the satisfaction of the
conditions precedent to the initial Loans hereunder or the issuance of the
initial Letter of Credit hereunder as set forth in Article 5 hereof, the
Existing Letter of Credit shall be a Letter of Credit for all purposes of this
Agreement (other than with respect to opening or transaction fees and the
payment of commissions made or accrued prior to the date hereof, which fees and
commissions shall be for the sole account of the Bank that issued the same), and
the Banks hereby affirm their pro rata participation (i.e., in accordance with
their respective Commitment Proportions) in such Letter of Credit.

            Section 2.7.  Term Loan Option.
                          ----------------

                                       23




       (a) Generally. If the Borrower requests Loans hereunder to fund a
           ---------
Permitted Acquisition on or before the Revolving Credit Termination Date and the
Permitted Acquisition Purchase Price equals or exceeds $5,000,000, the Borrower
may, by notice to the Banks delivered simultaneously with a notice of borrowing
pursuant to Section 3.1 hereof, elect to have such Loan recorded as a Term Loan.
Subject to the terms and conditions hereof, each of the Banks severally agrees
to make Term Loans to the Borrower on or before the Revolving Credit Termination
Date in an aggregate amount which when aggregated with such Bank's Commitment
Proportion of Aggregate Outstandings shall not exceed such Bank's Maximum
Commitment. All Term Loans shall be made by the Banks, on a pro rata basis in
accordance with their respective Commitment Proportions. In the event that
Borrower makes such election, the Revolving Credit Commitment of each Bank shall
be permanently reduced by the principal amount of any Term Loan made by such
Bank. The Term Loans initially may be Prime Rate Loans or LIBOR Loans or a
combination thereof, as determined by the Borrower and notified to the Banks in
accordance with Section 3.1; provided, however, that the minimum principal
                             --------
amount of any Prime Rate Loan shall be $250,000 and, if greater, integral
multiples of $50,000 and the minimum principal amount of any LIBOR Loan shall be
$1,250,000 and, if greater, integral multiples of $100,000.

       (b) Amortization of Term Loans. If a Term Loan is made by a Bank
           --------------------------
hereunder on or before July 31, 1998, the principal amount of such Term Loan
shall be repaid in sixteen (16) equal quarterly installments commencing on the
earlier of July 31, 1998 or the date six (6) months from the date on which such
Loan is made. If a Term Loan is made by a Bank hereunder after July 31, 1998,
the principal amount of such Term Loan shall be repaid in twelve (12) equal
quarterly installments commencing on the earlier of July 31, 1999 or the date
six (6) months from the date on which such Loan is made.

        (c) Interest Period; Conversions.
            ----------------------------

            (i) In the case of each Term Loan designated as a LIBOR Loan, the
Borrower shall select an Interest Period of any duration in accordance with the
definition of Interest Period in Section 1.1 hereof, subject to the limitation
that no Interest Period may extend beyond an Amortization Date, unless after
giving effect thereto, the aggregate principal amount of Term Loans that are
LIBOR Loans having Interest Periods which end after such Amortization Date shall
be less than or equal to the principal amount of Term Loans to be outstanding
hereunder after such Amortization Date.

            (ii) Upon the expiration of an Interest Period with respect to a 
Term Loan that is a LIBOR Loan, such Term Loan shall automatically be continued
as a Prime Rate Loan except to the extent that such Loan shall be prepaid
hereunder or unless the Borrower shall have notified the Banks, as provided in
Section 3.1 hereof of their intent to select a new Interest Period with respect
to such Term Loan. Subject to the following conditions, the Borrower shall have
the right to convert any Term Loan to a different type of Loan (i.e., from a
Prime Rate Loan to a LIBOR Loan and vice versa):
                                    ---- -----

                                       24




                  (w) if less than all Term Loans at the time outstanding shall
                  be converted, the notice given by the Borrower to the Banks
                  shall specify the aggregate amount of Term Loans to be
                  converted and such conversion shall be made ratably among the
                  Banks;

                  (x) no Term Loan may be converted to a LIBOR Loan less than
                  one month prior to the maturity date of such Loan;

                  (y) a LIBOR Loan may be converted to a different type of Loan
                  only on the last day of an Interest Period; and

                  (z) no Loan may be converted to a LIBOR Loan during the
                  occurrence and continuance of an Event of Default.

                  (iii) Notwithstanding anything to the contrary herein, after
giving effect to any Loan, unless consented to by the Banks in their sole
discretion, there shall not be more than one (1) Interest Period in effect in
respect of each Term Loan outstanding hereunder.


            (d)   The Term Notes. Each Term Loan made by each Bank hereunder 
                  --------------
shall be evidenced by a single promissory note of the Borrower substantially in
the form of Exhibit B hereto, with appropriate insertions, payable to the order
of such Bank and representing the obligation of the Borrower to pay the unpaid
principal balance of such Term Loan made by such Bank, with interest thereon as
provided herein. Each Bank is hereby authorized to record the type of its Term
Loan, the date and amount of each payment or prepayment of principal thereof,
the date and amount of each interest rate conversion pursuant to Section 2.7(c)
and the principal amount subject thereto and the interest rate applicable
thereto in such Bank's records and/or on a schedule annexed to and constituting
a part of its Term Note, and, absent manifest error, any such recordation shall
constitute conclusive evidence of the accuracy of the information so recorded;
provided, however, that the failure to make any such recordation shall not
affect the Borrower's obligations to repay the Term Loans. Each Term Note shall
(a) be dated the date such Term Loan is made, (b) be stated to mature in 16 or
12 equal quarterly installments, as provided above, and (c) shall bear interest
for a period from the date such Loan is made on the unpaid principal amount
thereof at the applicable rates per annum specified herein.

            (e) Use of Proceeds of Term Loans. The Borrower shall use the
                -----------------------------
proceeds of any Term Loan made hereunder to fund Permitted Acquisitions.

            Section 2.8.  Changes of Revolving Credit Commitments.
                          ---------------------------------------

            (a) The Borrower shall have the right to reduce or terminate the
amount of the unused Revolving Credit Commitments at any time and from time to
time provided that: (i) the Borrower shall give notice of each such reduction or
termination to the Banks as provided in Section 3.1, and (ii) each partial
reduction shall be allocated pro rata between the Revolving Credit Commitments
of each Bank in accordance with their respective Commitment Proportions


                                       25



and shall be in an aggregate amount at least equal to $1,000,000 or, if greater,
in integral multiples of $1,000,000.

            (b) The Revolving Credit Commitments, once reduced or terminated may
not be reinstated.

            (c) If the Revolving Credit Commitments are terminated pursuant to
this Section 2.8, the obligation of the Banks to make Term Loans hereunder shall
be terminated.

                                   ARTICLE 3.
                 GENERAL CREDIT PROVISIONS; FEES AND PAYMENTS.

            Section 3.1. Certain Notices. Except as otherwise provided in this
                         ---------------
Agreement, notices by the Borrower to the Banks of each borrowing pursuant to
Sections 2.4 and 2.7(a), each prepayment pursuant to Section 3.2, each reduction
or termination of the Revolving Credit Commitments pursuant to Section 2.8 and
each conversion of Loans pursuant to Sections 2.4 and 2.7(c) shall be
irrevocable and shall be effective on the date of receipt only if received by
all of the Banks, by not later than 11:00 a.m., New York City time, and (a) in
the case of borrowings and prepayments of (i) Prime Rate Loans, if given the
date thereof and (ii) LIBOR Loans, if given three (3) Banking Days prior
thereto; (b) in the case of reductions or terminations of the Revolving Credit
Commitments, given three (3) Banking Days prior thereto; and (c) in the case of
conversions pursuant to Sections 2.4 and 2.7(c), if given three (3) Banking Days
prior thereto. Each such notification which relates to a borrowing, continuation
or conversion shall specify the amount of the type of Revolving Credit Loan
(i.e., Prime Rate Loan or LIBOR Loan), the date of the proposed borrowing,
whether such Loan represents an additional borrowing, a continuation or a
conversion, and in the case of a LIBOR Loan, the Interest Period to be used in
the computation of interest with respect thereto. Each such notice relating to a
reduction or termination of the Revolving Credit Commitments shall specify the
amount of the Revolving Credit Commitments to be reduced or terminated. In
addition, if such notification relates to a borrowing to fund a Permitted
Acquisition, the Borrower shall notify the Banks of its election to have such
Loan recorded as a Revolving Credit Loan or a Term Loan as provided in Section
2.7(a) hereof. Finally, if the proceeds of any Revolving Credit Loan are to be
used by the Borrower to finance any Capital Expenditure, the notification with
respect to such borrowing shall include a statement to that effect indicating
the amount of the borrowing to be used for such purposes. Except for the amount
of the borrowing which shall be for each Bank its Commitment Proportion of the
total amount to be borrowed on such date, each notification delivered to the
Banks hereunder shall contain the same terms for each Bank.

            Section 3.2.  Prepayments.
                          -----------
            (a) The Borrower shall have the right at any time and from time to
time to prepay any Prime Rate Loan, in whole or in part; provided, however, that
each such partial prepayment of a Prime Rate Loan shall be in a minimum
aggregate principal amount of $250,000 or, if greater in amounts which are
integral multiples of $50,000. Except as required by


                                       26



paragraph (b) below or on the last day of an Interest Period with respect
thereto, the Borrower shall not be permitted to prepay LIBOR Loans.

            (b) In the event that the Aggregate Outstandings exceed the Total
Revolving Credit Commitments at any time prior to the Revolving Credit
Termination Date, the Borrower shall promptly pay or prepay so much of the Loans
outstanding as shall be necessary in order that the Aggregate Outstandings will
not exceed the Total Revolving Credit Commitments then in effect. All
prepayments under this subparagraph shall be subject to Section 4.1.

            (c) All payments required by paragraph (b) above shall be made to
the Banks pro rata in accordance with their respective Commitment Proportions
and shall be applied as follows: first, to outstanding Prime Rate Loans up to
the full amount thereof and then to outstanding LIBOR Loans up to the full
amount thereof; provided, however, that so long as no Default or Event of
Default has then occurred and is continuing, the Borrower shall not be required
to make any prepayment of any LIBOR Loan pursuant to this Section until the last
day of the Interest Period with respect thereto provided that an amount equal to
the amount of such prepayment is deposited by the Borrower with each Bank to be
held as Cash Collateral and second, if at such time there are undrawn Letters of
Credit outstanding, to provide Cash Collateral to be held by the Administrator
for the benefit of the Banks for application by the Administrator to the payment
of any drawing made under such Letters of Credit.

            (d) Any partial prepayment of Term Loans hereunder shall be applied
to the remaining installments of principal due on the Term Loans in inverse
order of maturity and amounts prepaid on any Term Loan may not be reborrowed.

            (e) All prepayments made pursuant to this Section 3.2 shall be
accompanied by the payment of all accrued interest on the amount so prepaid and
by all amounts required to be paid pursuant to Section 4.1 in connection
therewith.

            (f) If, after making the mandatory prepayment required by paragraph
(b) above, the Aggregate Letters of Credit Outstanding exceeds the Total
Revolving Credit Commitment, the Borrower agrees to provide the Administrator
with Cash Collateral in an amount equal to such excess.

            Section 3.3.  Interest on Loans.
                          -----------------

            (a) Prime Rate Loans. The Borrower shall pay interest on the
                ----------------
outstanding and unpaid principal amount of each Prime Rate Loan made under this
Agreement at a fluctuating rate per annum equal to the relevant Bank's Prime
Rate from time to time in effect, plus the applicable Margin. Each change in the
interest rate shall take effect simultaneously with the corresponding change in
the Prime Rate. Interest shall be calculated on the basis of the actual number
of days elapsed divided by a year of three hundred sixty (360) days and, with
respect to Revolving Credit Loans, shall be paid to each Bank in arrears on the
first day of each month commencing September 1, 1996, on the Revolving Credit
Termination Date and, with respect to Term Loans, shall be paid to each Bank in
arrears on the first day of each month commencing on


                                       27


the first day of the first month after the date such Loan is made and on the
maturity date of such Loan.

            (b) LIBOR Loans. The Borrower shall pay interest on the outstanding
                -----------
and unpaid principal amount of each LIBOR Loan made under this Agreement for
each Interest Period applicable to such LIBOR Loan at a rate per annum equal to
the Reserve Adjusted LIBOR Rate in effect with respect thereto, plus the
applicable Margin. Interest shall be calculated on the basis of the actual
number of days elapsed divided by a year of three hundred sixty (360) days and
shall be paid to each Bank in arrears on the last day of the Interest Period
applicable to such LIBOR Loan; provided, however, that if such Interest Period
                               --------
is longer than three months, interest shall be paid on the last day of each
three-month period following the commencement of such Interest Period and on the
last day of such Interest Period.

            (c) Post-Default. If any Default or Event of Default has occurred
                ------------
and is continuing hereunder, all Loans, and all interest, fees or other amounts
due hereunder, to the extent permitted by applicable law, shall bear interest
(payable on demand, and in any event on the last day of each month, and computed
daily on the basis of a 360-day year for actual days elapsed) (i) in all cases
other than LIBOR Loans, at the Default Rate until paid and (ii) in the case of
LIBOR Loans, at a rate which shall be the greater of (x) the Default Rate or (y)
2% per annum in excess of the rate applicable to such LIBOR Loan, until the
expiration of the Interest Period applicable to such Loan, at which time the
Loan will automatically be converted into a Prime Rate Loan, and until paid,
shall bear interest at the Default Rate. In no event, however, shall interest
payable hereunder be in excess of the maximum rate of interest permitted under
applicable law. The obligation to so pay interest upon any reimbursement
obligation of the Borrower to the Banks shall not be construed so as to waive
the requirement for reimbursement on the same date that payment is made by the
Banks as set forth in this Agreement.

            Section 3.4. Term Loan Fee. The Borrower shall pay to each Bank a
                         -------------
term loan fee equal to 0.25% of each Term Loan made by such Bank hereunder. The
term loan fee shall be due and payable simultaneously with the making of each
Term Loan hereunder.

            Section 3.5. Commitment Fee. The Borrower shall pay to each Bank a
                         --------------
commitment fee for the period from and including the date hereof to and
excluding the Revolving Credit Termination Date equal to such Bank's Commitment
Proportion of an amount equal to the product of (a) the applicable Margin during
the applicable period multiplied by (b) the average daily unused portion of the
Total Revolving Credit Commitment during the applicable period. The commitment
fee shall be calculated on the basis of a year of 360 days for the actual number
of days elapsed. The commitment fee shall be due and payable quarterly in
arrears on the first day of each calendar quarter and on the Revolving Credit
Termination Date.

            Section 3.6.  Administration Fee.  The Borrower shall pay to the 
                          ------------------
Administrator an annual fee of $10,000.  The administration fee shall be 
due and payable annually in advance on the date hereof and on each 
anniversary of the date hereof.


                                       28




            Section 3.7. Letter of Credit. The Borrower shall pay to the
                         ----------------
Administrator, for its sole account, transaction fees in an amount or amounts
which are normally charged by the Administrator to comparable customers in
connection with the issuance of Letters of Credit. In addition, the Borrower
shall pay to the Administrator on behalf and for the ratable benefit of each of
the Banks, one and one-half percent (1.50%) per annum of the face amount of each
Letter of Credit, subject to the minimum fee from time to time (i.e.,
customarily charged to comparable customers with respect to Letters of Credit),
payable, in advance, at the time of issuance of such Letter of Credit.

            Section 3.8.  Facility Fee.  The Borrower shall pay to each Bank a 
                          ------------
facility fee equal to 0.25% of such Bank's Revolving Credit Commitment.  The 
Banks acknowledge receipt of such fee.

            Section 3.9.  Payments Generally.
                          ------------------

            (a) All payments under this Agreement or the Notes, shall be made in
Dollars in immediately available funds to each Bank in an amount equal to its
Commitment Proportion of such payment not later than 1:00 p.m. New York City
time on the relevant dates specified above (each such payment made after such
time on such due date is to be deemed to have been made on the next succeeding
Banking Day), to such Bank's Principal Office. The Borrower will notify the
Banks of any payment pursuant to the provisions of this Section at the same time
it makes any such payment. Each Bank may (but shall not be obligated to) debit
the amount of any such payment to any ordinary deposit account of the Borrower
with such Bank; provided, however, that the Banks shall not be permitted to
debit any funds which are not available to the Borrower other than on an
overdraft basis. The Borrower shall, at the time of making each payment under
this Agreement or the Notes, specify to the Banks the principal or other amount
payable by the Borrower under this Agreement or the Notes to which such payment
is to be applied; provided, however, that in the event that the Borrower fails
to so specify, or if a Default or an Event of Default has occurred and is
continuing, the Banks shall apply such payment as they may elect in their sole
discretion. If the due date of any payment under this Agreement or the Notes
would otherwise fall on a day which is not a Banking Day, such date shall be
extended to the next succeeding Banking Day and interest shall be payable for
any principal so extended for the period of such extension.

            (b) All payments made by the Borrower under this Agreement, the
Notes or the other Facility Documents shall be made free and clear of, and
without deduction or withholding for or on account of, any present or future
income, stamp or other taxes, levies, imposts, duties, charges, fees, deductions
or withholdings, now or hereafter imposed, levied, collected, withheld or
assessed by any governmental or taxing authority of any jurisdiction located
outside of the United States, excluding, (x) in the case of each Bank, income
taxes and franchise taxes (imposed in lieu of income taxes) imposed on such Bank
as a result of a present or former connection between the jurisdiction of the
government or the taxing authority imposing such tax and such Bank (excluding a
connection arising solely from such Bank having executed, delivered, or
performed its obligations or received a payment under, or enforced, this
Agreement, the Notes or the other Facility Documents) or any political
subdivision or taxing authority

                                       29



thereof or therein, and (y) taxes (including withholding taxes) imposed by
reason of the failure of the Administrator or any Bank, in either case that is
organized outside the United States, to comply with Section 3.9(c) hereof (or
the inaccuracy at any time of the certificates, documents and other evidence
delivered thereunder) (all such non-excluded taxes, levies, imposts, duties,
charges, fees, deductions and withholdings being hereinafter called "Taxes"). If
any Taxes are withheld from any amounts payable to any Bank hereunder or under
the Facility Documents, the amounts so payable to such Bank shall be increased
to the extent necessary to yield to such Bank (after payment of all Taxes)
interest or any such other amounts payable hereunder at the rates or in the
amounts specified in this Agreement, the Notes and the other Facility Documents.
Whenever any Taxes are payable by the Borrower, the Borrower shall send to such
Bank within 30 days after the date of any payment, a certified copy of an
original official receipt received by the Borrower showing payment thereof. If
the Borrower fails to pay any Taxes when due to the appropriate taxing authority
or fails to remit to the Banks the required receipts or other required
documentary evidence, the Borrower shall indemnify the Banks for any incremental
taxes, interest or penalties that may become payable by any Bank as a result of
any such failure. This indemnification shall be made within 30 days from the
date such Bank or the Administrator (as the case may be) makes written demand
therefor. If any Bank receives a refund in respect of any Taxes for which such
Bank has received payment from the Borrower hereunder, such Bank shall promptly
notify the Borrower of such refund and such Bank shall, within 30 days of
receipt of a request by the Borrower repay such refund to the Borrower, provided
that the Borrower, upon the request of such Bank, agrees to return such refund
(plus any penalties, interest or other charges) to such Bank in the event such
Bank is required to repay such refund. The agreements in this subsection shall
survive the termination of this Agreement and the Facility Documents and the
payment of the Notes and all other amounts payable hereunder or thereunder.

            (c) Each Bank that is organized outside of the United States shall
deliver to the Borrower on the date hereof (or, in the case of an assignee, on
the date of the assignment) and from time to time as required for renewal under
applicable law duly completed copies of United States Internal Revenue Service
Form 1001 or 4224 (or any successor or additional forms), as appropriate,
indicating in each case that such Bank is entitled to receive payments under
this Agreement without any deduction or withholding of any United States federal
income taxes. Each Bank that is organized outside the United States shall
promptly notify the Borrower and each other Bank of any change in its Lending
Office and upon written request of the Borrower such Bank shall, prior to the
immediately following due date of any payment by the Borrower or any Guarantor
hereunder or under any other Facility Document, deliver to the Borrower or such
Guarantor, as the case may be (with copies to each other Bank), such
certificates, documents or other evidence, as required by the Code or Treasury
Regulations issued pursuant thereto, including without limitation Internal
Revenue Service Form 4224, Form 1001 and any other certificate or statement of
exemption required by Treasury Regulation Section 1.1441-4(a) or Section 1.
1441-6(c) or any subsequent version thereof, properly completed and duly
executed by such Bank establishing that such payment is (i) not subject to
withholding under the Code because such payment is effectively connected with
the conduct by such Bank of a trade or business in the United States or (ii)
totally exempt from United States tax under a provision of an applicable tax
treaty. The Borrower shall be entitled to rely on such forms in their possession
until receipt of any revised or successor form pursuant to this Section 3.9(c).
If the Administrator

                                       30



or a Bank fails to provide a certificate, document or other evidence required
pursuant to this Section 3.9(c), then (i) the Borrower shall be entitled to
deduct or withhold on payments to the Administrator or such Bank as a result of
such failure, as required by law, and (ii) the Borrower shall not be required to
make payments of additional amounts with respect to such withheld Taxes pursuant
to clause (x) of Section 3.9(c) to the extent such withholding is required
solely by reason of the failure of the Administrator or such Bank to provide the
necessary certificate, document or other evidence.


                                   ARTICLE 4.
                             YIELD PROTECTION, ETC.

            Section 4.1.  Certain Compensation.
                          --------------------

            (a) The Borrower hereby agrees to indemnify the Banks against any
loss or expense which the Banks or any one of them may sustain or incur as a
consequence of any of the following:

                (i) the receipt or recovery by a Bank, whether by voluntary
prepayment, acceleration or otherwise, of all or any part of a LIBOR Loan prior
to the last day of an Interest Period applicable thereto;

                (ii) the conversion, prior to the last day of an applicable 
Interest Period, of a LIBOR Loan into a Prime Rate Loan;

                (iii) the failure by the Borrower to borrow any LIBOR Loan, 
convert any Prime Rate Loan to a LIBOR Loan or continue any LIBOR Loan on the
date of borrowing, conversion or continuation set forth in the notice delivered
by the Borrower pursuant to the provisions hereof, unless such failure to borrow
results from the Banks' failure to fund such borrowing when the Banks are
required to do so under the terms of this Agreement; or

                (iv) the failure by the Borrower to pay, punctually on the due 
date thereof, any amount payable by the Borrower with respect to or on account
of any LIBOR Loan.

            Without limiting the effect of the foregoing, the amount to be paid
by the Borrower to any Bank in order to so indemnify such Bank for any loss
occasioned by any of the events described in the preceding paragraph, and as
liquidated damages therefor, shall be equal to the excess, discounted to its
present value as of the date paid to such Bank, of (i) the amount of interest
which otherwise would have accrued on the principal amount so received,
recovered, converted or not borrowed during the period (the "Indemnity Period")
commencing with the date of such receipt, recovery, conversion, or failure to
borrow to the last day of the applicable Interest Period for such LIBOR Loan at
the rate of interest applicable to such LIBOR Loan (or the rate of interest
agreed to in the case of a failure to borrow) provided for herein (prior to
default) over (ii) the amount of interest which would be earned by such Bank
during the Indemnity Period if it invested the principal amount so received,
recovered, converted or not

                                       31



borrowed at the rate per annum approximately equal to LIBOR, as the case may be,
on an amount approximately equal to such principal amount for a period of time
comparable to such Indemnity Period.

            (b) Any Bank requesting indemnification pursuant to this Section 4.1
shall deliver to the Borrower a certificate as to any additional amounts payable
pursuant to this Section 4.1 setting forth the basis and method of determining
such amounts shall be conclusive, absent manifest error, as to the determination
by each Bank set forth therein if made reasonably and in good faith. The
Borrower shall pay to each Bank any amounts so certified by such Bank within 10
days of receipt of any such certificate. For purposes of this Section 4. 1, all
references to the "Bank" shall be deemed to include any participant in this
Agreement and/or the Loans.

            Section 4.2.  Additional Costs.
                          ----------------

            (a) The Borrower shall pay to each Bank, from time to time, on
demand of any such Bank, such amounts as such Bank may reasonably determine to
be necessary to compensate it for any costs which Bank reasonably determines are
attributable to its obligation to make any Loan or issue any Letter of Credit
hereunder, or any reduction in any amount receivable by such Bank hereunder in
respect of any such Loans or Letters of Credit or such obligation (such
increases in costs and reductions in amounts receivable being herein called
"Additional Costs"), resulting from any Regulatory Change which: (i) changes the
basis of taxation of any amounts payable to such Bank under this Agreement or
its Note or any Letter of Credit in respect of any such obligations (other than
taxes imposed on the overall net income of such Bank for any of such obligations
by the jurisdiction in which such Bank has its principal office or Lending
Office or franchise taxes imposed in lieu of income taxes); or (ii) imposes or
modifies any reserve, special deposit, deposit insurance or assessment, minimum
capital, capital ratio or similar requirements relating to any extensions of
credit or other assets of, or any deposits with or other liabilities of, such
Bank (including any of such Loans or any deposits referred to in the definitions
of "LIBOR Loans" or "Letters of Credit"); or (iii) imposes any other condition
affecting this Agreement, or its Note (or any of such extensions of credit or
liabilities) or any Letter of Credit and such Bank's obligations with respect
thereto. Each Bank will notify the Borrower and the other Bank of any event
occurring after the date of this Agreement which will entitle such Bank to
compensation pursuant to this Section 4.2(a) as promptly as practicable after it
obtains knowledge thereof and determines to request such compensation.
Notwithstanding anything herein to the contrary, no provision of this Section
4.2(a) shall be deemed to require the Borrower to make any payment of any amount
to the extent that such payment would duplicate any payment made by the Borrower
pursuant to Section 3.9 hereof.

            (b) Without limiting the effect of the foregoing provisions of this
Section 4.2, in the event that, by reason of any Regulatory Change, any Bank
either (i) incurs Additional Costs based on or measured by the excess above a
specified level of the amount of a category of deposits or other liabilities of
such Bank which includes deposits by reference to which the interest rate on
LIBOR Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of such Bank which includes LIBOR Loans or
(ii) becomes subject to restrictions on the amount of such a category of
liabilities or assets which it may hold,

                                       32



then, if such Bank so elects by notice to the Borrower, the obligation of such
Bank to make LIBOR Loans hereunder shall be suspended until the date such
Regulatory Change ceases to be in effect (in which case the provisions of
Section 4.5 shall be applicable).

            (c) Without limiting the effect of the foregoing provisions of this
Section 4.2 (but without duplication), the Borrower shall pay to each Bank from
time to time on request such amounts as such Bank may reasonably determine to be
necessary to compensate such Bank for any costs which it reasonably determines
are attributable to the maintenance by it or any of its Affiliates pursuant to
any law or regulation of any jurisdiction or any interpretation, directive or
request (whether or not having the force of law and whether in effect on the
date of this Agreement or thereafter) of any court or governmental or monetary
authority, of capital in respect of its Loans or other obligations hereunder
(such compensation to include, without limitation, an amount equal to any
reduction in return on assets or equity of such Bank to a level below that which
it could have achieved but for such law, regulation, interpretation, directive
or request). Each Bank will notify the Borrower if it is entitled to
compensation pursuant to this Section 4.2(c) as promptly as practicable after it
determines to request such compensation.

            (d) A statement of any Bank setting forth such amount or amounts,
supported by calculations in reasonable detail, as shall be necessary to
compensate such Bank as specified in paragraphs (a), (b) and (c) above shall be
delivered to the Borrower and shall be conclusive absent manifest error. The
Borrower shall pay each such Bank the amount shown as due on any such statement
within ten (10) days after its receipt of the same.

            (e) Any Bank claiming any additional amounts payable pursuant to
this Section 4.2 agrees to use reasonable efforts (consistent with legal and
regulatory restrictions) to designate a different Lending Office if the making
of such a designation would avoid the need for, or reduce the amount of, any
such additional amounts and would not, in the reasonable judgment of such Bank,
be otherwise disadvantageous to such Bank.

            Section 4.3.  Limitation on Types of Loans.  Anything herein to the
                          ----------------------------
contrary notwithstanding, if: 

            (a) any Bank determines (which determination shall be conclusive)
that quotations of interest rates for the relevant deposits referred to in the
definition of "LIBOR Loans" in Section 1.1 are not being provided in the
relevant amounts or for the relevant maturities for purposes of determining the
rate of interest for any LIBOR Loans as provided in this Agreement; or

            (b) any Bank determines (which determination shall be conclusive)
and notifies the Borrower that the relevant rates of interest referred to in the
definition of "LIBOR Loans" in Section 1.1 upon the basis of which the rate of
interest for any type of LIBOR Loans is to be determined do not adequately cover
the cost to such Bank of making or maintaining such Loans, then, such Bank shall
as soon as practicable thereafter give written notice (or facsimile notice
promptly confirmed in writing) of such determination to the Borrower, and any
request by the Borrower for the making of a LIBOR Loan or conversion or
continuation of any Loan into a

                                       33



LIBOR Loan, in each case, pursuant to the provisions hereof shall, until the
circumstances giving rise to such notice no longer exist, be deemed to be a
request for a Prime Rate Loan. Each determination by a Bank made hereunder shall
be conclusive absent manifest error.

            Section 4.4. Illegality. Notwithstanding any other provision in this
                         ----------
Agreement, in the event that it becomes unlawful for any Bank or its Lending
Office to honor its obligation to make or maintain LIBOR Loans hereunder, then
such Bank shall promptly notify the Borrower thereof and such Bank's obligation
to make or maintain LIBOR Loans hereunder shall be suspended until such time as
such Bank may again make and maintain such affected Loans (in which case the
provisions of Section 4.5 shall be applicable).

            Section 4.5. Certain LIBOR Loans Pursuant To Sections 4.2. 4.3 and
                         ------------------------------------------------------
4.4. If an event referred to in Section 4.2, 4.3 or 4.4 has occurred, the
- - ---
affected Bank shall be required to make Prime Rate Loans in accordance with this
Agreement, and all LIBOR Loans of such Bank then outstanding shall be
automatically converted into Prime Rate Loans on the date specified by such Bank
in such notice (which shall be, for each LIBOR Loan, the last day of the
Interest Period applicable thereto unless such Bank determines that it is
required by law to convert such LIBOR Loan on an earlier date in which case such
earlier date shall be the date of conversion), and, to the extent that LIBOR
Loans are so made as (or converted into) Prime Rate Loans, all payments of
principal which would otherwise be applied to such Bank's LIBOR Loans shall be
applied instead to its Prime Rate Loans. In the event of any conversion of any
LIBOR Loan to a Prime Rate Loan pursuant to Section 4.5 prior to the maturity
date with respect to such LIBOR Loan the Borrower shall pay to the relevant Bank
all amounts required to be paid pursuant to Section 4.1 hereof.

            Section 4.6. Survival. The indemnities and other obligations set
                         --------
forth in this Article 4 shall survive payment in full of all Loans or extensions
of credit made pursuant to this Agreement and the Final Maturity Date.

specifically provided hereunder and subject to Permitted Liens, to create a
valid and perfected first priority security interest in and to property
purported to be subject to such agreement other than by the failure of the
Collateral Agent to file any continuation statements required to be filed under
the Uniform Commercial Code as in effect in any jurisdiction in which such
property may be located; or (b) to be in full force and effect or shall be
declared null and void, or the validity of enforceability thereof shall be

                          --------
hereunder, the Required Banks may, by notice to the Borrower, (i) declare the
Revolving Credit Commitments and all obligations of the Banks to make Term Loans
to be terminated, whereupon the same shall forthwith terminate, and (ii) declare
the outstanding principal of the Notes, all interest thereon and all other
Obligations to be forthwith due and payable, whereupon the Notes, all such
interest and all such amounts shall become and be forthwith due and payable,

            Section 12.1. Indemnification of Administrator. The Banks agree to
                          --------------------------------
indemnify the Administrator (to the extent not reimbursed under Section 13.3 or
under the applicable provisions of any other Facility Document, but without
limiting the obligations of the Borrower under Section 13.3 or such provisions),
ratably in accordance with the aggregate unpaid principal amount of the Loans
made by the Banks (without giving effect to any participation, in all or any
portion of such Loans, sold by them to any other Person) or, if no Loans are at
the time outstanding, ratably in accordance with their respective Revolving
Credit Commitments, for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted
against the Administrator in any way relating to or arising out of this
Agreement, any other Facility Document or any other documents contemplated by or
referred to herein or the transactions contemplated hereby or thereby
(including, without limitation, the costs and expenses which the Borrower is
obligated to pay under Section 13.3 or under the applicable provisions of any
other Facility Document but excluding, unless a Default or Event of Default has
occurred, normal administrative costs and expenses incidental to the performance
of its agency duties hereunder) or the enforcement of any of the terms hereof or
thereof or of any such other documents or instruments.

            Section 12.2. Non-Reliance on Administrator and Other Banks. Each
                          ---------------------------------------------
Bank agrees that it has, independently and without reliance on the Administrator
or any other Bank, and based on such documents and information as it has deemed
appropriate, made its own credit analysis of the Borrower and the Guarantors and
decision to enter into this Agreement and that it will, independently and
without reliance upon the Administrator or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own analysis and decisions in taking or not taking action under this
Agreement or any other Facility Documents. The Administrator shall not be
required to keep itself informed as to the performance or observance by the
Borrower, the Guarantors of this Agreement or any other Facility Documents or
any other document referred to or provided for herein or therein or to inspect
the properties or books of the Borrower or the Guarantor.

            Section 12.3. Several Obligations and Rights of Banks. The failure
                          ---------------------------------------
of any Bank to make any Loan to be made by it on the date specified therefor
shall not relieve any other Bank of its obligation to make its Loan on such
date, but no Bank shall be responsible for the failure of any other Bank to make
a Loan to be made by such other Bank or the failure of the Administrator to
issue a Letter of Credit. The amounts payable at any time hereunder to each Bank
shall be a


                                       55


separate and independent debt, and each Bank shall be entitled to protect and
enforce its rights arising out of this Agreement, and it shall not be necessary
for any other Bank to be joined as an additional party in any proceeding for
such purpose.

            Section 12.4. Pro Rata Treatment of Loans, Etc. Except to the extent
                          --------------------------------
otherwise provided in this Agreement: (a) each borrowing under Sections 2.4 or
2.7(a) or issuance of Letters of Credit under Section 2.6 shall be made from or
for the benefit of the Banks and each conversion of a Loan from one type of Loan
to another pursuant to Sections 2.4 and 2.7(c) shall be made for the accounts of
the Banks, pro rata in accordance with their respective Commitment Proportions;
(b) each prepayment and payment of principal of or interest on Loans of a
particular type and a particular Interest Period shall be made to the Banks pro
rata in accordance with the respective unpaid principal amounts of such Loans of
such Interest Period held by such Banks. Each reimbursement of a drawing under a
Letter of Credit shall be made to the Administrator for the ratable benefit of
the Banks in accordance with their respective participations in such Letter of
Credit.

            Section 12.5. Sharing of Payments Among Banks. Each Bank agrees that
                          -------------------------------
if it shall, through the exercise of a right of banker's lien, set-off,
counterclaim or otherwise, obtain any payments from the Borrower or any of the
Guarantors, all such payments shall first be applied to the repayment of the
outstanding Obligations, and such Bank will (a) be deemed to have simultaneously
purchased from the other Banks a share in the Obligations held by such Banks so
that the amount of the Obligations held by each of the Banks shall be on a pro
rata basis (provided, however, that for purposes of this Section, the term
"pro-rata" will be determined with respect to each Bank's Commitment Proportion
of outstanding Obligations after subtraction in each case of amounts, if any, by
which any such Bank has not funded an amount equal to its Commitment Proportion
of outstanding Obligations) and (b) make such disposition and arrangements with
the other Banks with respect to such payments, either by way of distribution,
pro tanto assignment of claims, subrogation or otherwise as shall result in each
Bank receiving in respect of such payments its Commitment Proportion thereof as
contemplated hereby. If all or any portion of any of the payments referenced
above is thereafter recovered from the Bank which received the same, the
purchase provided in this Section shall be rescinded to the extent of such
recovery, without interest. The Borrower and the Guarantors expressly consent to
the foregoing arrangements and agree that each Bank so purchasing a portion of
the other Banks' Obligations may exercise all rights of payment with respect to
such portion as fully as if such Bank were the direct holder of such portion.

            Section 12.6. Rights of Administrator as Bank. With respect to its
                          -------------------------------
Commitment and the Loans made by it, the Administrator in its capacity as a Bank
hereunder shall have the same rights and powers hereunder as any other Bank and
may exercise the same as though it was not acting as the Administrator, and the
term "Bank" or "Banks" shall, unless the context otherwise indicates, include
the Administrator in its capacity as a Bank. The Administrator or any Bank and
their respective Affiliates may (without having to account therefor to any other
Bank except as otherwise expressly provided in this Agreement) accept deposits
from, lend money to (on a secured or unsecured basis), and generally engage in
any kind of banking, trust or other business with, the Borrower (and any of its
Affiliates); provided that no payment or lien

                                       56



priority shall be given to the Administrator or to any Bank for any other
transaction without the express written approval of all of the other Banks.
Although the Administrator or a Bank or any of their respective Affiliates may
in the course of such relationships and relationships with other Persons acquire
information about the Borrower, its Affiliates and such other Persons, neither
the Administrator nor such Bank shall have any duty to the other Banks or the
Administrator to disclose such information to the other Banks or the
Administrator.

                                 MISCELLANEOUS.

            Section 13.1. Amendments and Waivers. Except as otherwise expressly
                          ----------------------
provided in this Agreement, any provision of this Agreement may be amended or
modified only by an instrument in writing signed by the Borrower and the
Required Banks, and any provision of this Agreement may be waived by the
Borrower and by an instrument signed by the Required Banks (if such provision
requires performance by the Borrower), including, but not limited to, any Event
of Default; provided that no amendment, modification or waiver shall, unless by
            --------
an instrument signed by all of the Banks: (a) increase or extend the term, or
extend the time or waive any requirement for the reduction or termination of or
otherwise change the Revolving Credit Commitment or the obligation to make Term
Loans of any Bank, (b) extend the date fixed for the payment of principal of or
interest on any Loan, (c) reduce the amount of any payment of principal thereof
or the rate at which interest is payable thereon or any fee payable hereunder,
(d) alter the terms of this Section 13. 1, (e) change the fees payable to any
Bank except as expressly otherwise provided herein, (f) permit the Borrower, or
any of the Guarantors, to transfer or assign any of its obligations hereunder or
under the Facility Documents, (g) release the security interest in and Lien on
or the right to a security interest in and Lien on the Collateral, or (h) change
the definition of the term "Required Banks." No failure on the part of any Bank
to exercise, and no delay in exercising, any right hereunder shall operate as a
waiver thereof or preclude any other or further exercise thereof or the exercise
of any other right. The remedies herein provided are cumulative and not
exclusive of any remedies provided by law.

            Section 13.2. Usury. Anything herein to the contrary
                          -----
notwithstanding, the Obligations shall be subject to the limitation that
payments of interest shall not be required to the extent that receipt thereof
would be contrary to provisions of law applicable to a Bank limiting rates of
interest which may be charged or collected by such Bank. If any of the
above-referenced payments of interest, together with any other charges or fees
deemed in the nature of interest, exceed the maximum legal rate, then the Banks
shall have the right to make such adjustments as are necessary to reduce any
such aggregate interest rate (based on the foregoing aggregate amount) to the
maximum legal rate, and if any Bank ever receives, collects or applies any such
excess, it shall be deemed a partial repayment of principal and treated as such;
and if principal is paid in full, any remaining excess shall be refunded to the
Borrower. The Borrower waives any right to prior notice of such adjustment and
further agrees that any such adjustment may be made by the Banks subsequent to
notification from the Borrower that such aggregate interest charged exceeds the
maximum legal rate.

            Section 13.3. Expenses and Indemnification. The Borrower shall
                          ----------------------------
reimburse each of the Banks on demand for all reasonable costs, expenses and
charges (including, without limitation, reasonable fees and charges of such
Banks' special counsel, Rivkin, Radler & Kremer, plus disbursements, but
excluding the fees and charges of any other counsel for or to any of the Banks
incurred in connection with or relation to the documentation, negotiation and
closing of the transactions contemplated hereby, and their respective
disbursements) incurred by such Bank in connection with the preparation, review,
execution and delivery of this Agreement and the Facility Documents. Without
limiting the generality of the foregoing, the Borrower shall pay all recording
fees and charges and recording taxes incurred by any of the Banks hereunder or
in connection herewith. In addition, the Borrower shall reimburse each Bank for
all of its reasonable costs and expenses in connection with the perfection,
protection, enforcement or preservation of any rights under this Agreement, the
Notes or the other Facility Documents. The Borrower agrees to indemnify each
Bank and their respective directors, officers, employees, representatives and
agents from, and hold each of them harmless against, any and all losses,
liabilities, claims, damages or expenses of any kind (including, without
limitation, the reasonable fees and expenses of counsel for such Person in
connection with any investigative, administrative or judicial proceeding,
whether or not such Person shall be designated a party thereto) incurred by any
of them (or the Administrator or the Collateral Agent in connection with their
actions in their respective capacities hereunder) arising out of or by reason of
any investigation or litigation or other proceedings (including any threatened
investigation or litigation or other proceedings) relating to or arising out of
this Agreement, any actual or proposed use by the Borrower of the proceeds of
the Loans or any Letters of Credit, or to the failure of the Borrower to perform
or observe any of the terms, covenants or conditions on its part to be performed
or observed under this Agreement or under any of the Facility Documents. The
indemnity provided in this Section shall not extend to any such losses,
liabilities, claims, damages or expenses incurred by reason of the gross
negligence, willful misconduct or bad faith of the Person to be indemnified.

            Section 13.4. Survival. The obligations of the Borrower under
                          --------
Section 2.3, Article 4 and Section 13.3 shall survive the repayment of the Loans
and the Final Maturity Date for a period corresponding to the maximum applicable
statute of limitations in effect in the State of New York from time to time.

            Section 13.5. Assignment; Participation. This Agreement shall be
                          -------------------------
binding upon, and shall inure to the benefit of Borrower, the Banks and their
respective successors and assigns, except that the Borrower may not assign or
transfer its rights or obligations hereunder. Each Bank may assign, or sell
participation in, all or any part of any Loan to another bank or other entity,
in which event (a) in the case of an assignment, upon notice thereof by the Bank
to the Borrower, the assignee shall have, to the extent of such assignment
(unless otherwise provided therein), the same rights, benefits and obligations
(including, without limitation, a ratable assumption of the assigning Bank's
Revolving Credit Commitment, obligation to make Term Loans and Commitment
Proportion hereunder) as it would have if it were a Bank hereunder; and (b) in
the case of a participation, the participant shall have no rights under the
Facility Documents and all amounts payable by the Borrower under Articles 2 and
3 shall be determined as if such Bank had not sold such participation. Such Bank
may furnish any information concerning the Borrower in the possession of such
Bank from time to time to assignees and


                                       58


participants (including prospective assignees and participants); provided that
such Bank shall require any such prospective assignee or such participant
(prospective or otherwise) to agree in writing to maintain the confidentiality
of such information. There shall be no limit on the number of assignments or
participants that may be granted by any Bank. Notwithstanding any such
assignment, any rights and remedies available to the Borrower for any breaches
by an assigning Bank of its obligations hereunder while a Bank shall be
preserved after such assignment and such Bank shall not be relieved of any
liability to the Borrower due to such breach.

            Section 13.6. Special Provisions Regarding Designation of Agent. If
                          -------------------------------------------------
the number of Banks party to this Agreement increases to three or more at any
time, Fleet will automatically and without further action by the Banks hereunder
be designated as the agent for the Banks hereunder and in such capacity shall be
referred to as the Agent. In any such event, Section 1.1 of this Agreement shall
be amended as provided in Schedule 13.6-A and the provisions of Articles 2, 3, 4
and 12 of this Agreement shall be deleted and the corresponding provisions
included in Schedule 13.6-B hereto shall be substituted in their place. To the
extent that any further provisions of this Agreement require further revision in
order to give effect to the provisions of the new Articles 2, 3, 4 and 12 the
parties hereto agree to cause such additional amendments to be effected as
promptly as is practical to give effect to the provisions of the new Articles 2,
3, 4 and 12. Furthermore, each of the Banks agrees that upon Fleet being
designated as Agent pursuant to this Section 13.6, all Notes outstanding will be
modified to conform to the provisions of new Articles 2, 3, 4 and 12.

            Section 13.7. Notices. Unless the party to be notified otherwise
                          -------
notifies the other party in writing as provided in this Section, and except as
otherwise provided in this Agreement, notices shall be given to the Borrower by
certified or registered mail or by recognized overnight delivery services to
such party at its address on the signature page of this Agreement. In addition,
notices of borrowing pursuant to Section 2.4 or Section 2.7(c) may be delivered
by telecopier, provided that such telecopied notices shall be confirmed by
sending the original signed copy of such notice to the Banks by certified or
registered mail or by recognized overnight delivery services. Initially, notice
shall be delivered to each party hereto at the addresses set forth on the
signature page hereof. Notices shall be effective: (a) if given by registered or
certified mail, 72 hours after deposit in the mails with postage prepaid,
addressed as aforesaid; or (b) if given by recognized overnight delivery
service, on the Banking Day following deposit with such service addressed as
aforesaid; or (c) if given by telecopy, when the telecopy is transmitted to the
telecopy number as aforesaid and confirmed with a confirmation receipt.

            Section 13.8. Setoff. The Borrower agrees that, in addition to (and
                          ------
without limitation of) any right of setoff, banker's lien or counterclaim a Bank
may otherwise have, each Bank shall be entitled, at its option without any prior
notice to the Borrower (any such notice being expressly waived by the Borrower
to the extent permitted by applicable law), to offset balances (general or
special, time or demand, provisional or final) held by it for the account of the
Borrower at any offices of such Bank or any of its Affiliates, in Dollars or in
any other currency, against any amount payable by the Borrower to such Bank
under this Agreement or such Bank's Note which is not paid when due (regardless
of whether such balances are then due

                                       59


to the Borrower), in which case it shall promptly notify the Borrower thereof;
provided that such Bank's failure to give such notice shall not affect the
validity thereof. Payments by the Borrower thereof hereunder shall be made
without setoff or counterclaim.

            Section 13.9.  Jurisdiction; Immunities.
                           ------------------------

(INCLUDING ANY APPLICABLE APPEALS) IN ANY SUCH ACTION OR PROCEEDING SHALL BE
CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR
IN ANY OTHER MANNER PROVIDED BY LAW. THE BORROWER FURTHER WAIVES ANY OBJECTION

OF ANY BANK TO BRING ANY ACTION OR PROCEEDING AGAINST THE BORROWER, OR ITS
PROPERTY IN THE COURTS OF ANY OTHER JURISDICTIONS.

            (c) TO THE EXTENT THAT THE BORROWER HAS OR HEREAFTER MAY ACQUIRE ANY

and interpreted and construed in accordance with, the law of the State of New
York.

            Section 13.15. Further Rights of the Banks.
                           ---------------------------

            (a) The Borrower shall do all things and shall deliver all
instruments reasonably requested by Banks to protect or perfect any Lien given
hereunder or in connection herewith including, without limitation, financing
statements under the Uniform Commercial Code, and all documents and instruments
necessary under the Federal Assignment of Claims Act. The Borrower authorizes
the Banks to execute alone any financing statement or other documents or
instruments that the Banks may require to perfect, protect or establish any Lien
hereunder or in connection herewith and further authorizes the Banks to sign
their names on the same. The Borrower appoints such person or persons as the
Banks may designate as its attorney-in-fact to, upon the exercise by the Banks
of their remedies set forth in Section 10.2 hereof, endorse the name of the
Borrower on any checks, notes, drafts or other forms of payment or security that
may come into the possession of any Bank, to sign the Borrower's name on
invoices or bills of lading, drafts against customers, notices of assignment,
verifications and schedules and, generally, to do all things necessary to carry
out this Agreement and the Facility Documents. Upon the exercise by the Banks of
their remedies set forth in Section 10.2 hereof, such attorney-in-fact may
notify the Post Office authorities to change the address of delivery of mail to
an address designated by the Banks, and open and dispose of mail addressed to
the Borrower. The powers granted herein, being coupled with an interest, are
irrevocable, and the Borrower approve and ratify all acts of the
attorney-in-fact. Neither the Banks nor the attorney-in-fact shall be liable for
any act or omission, error in judgment or mistake of law so long as the same is
not willful misconduct or grossly negligent.


                                       61




            (b) In the event that the Borrower shall fail to purchase or
maintain insurance (where applicable), or to pay any tax, assessment, government
charge or levy, except as the same may be otherwise permitted hereunder, or in
the event that any Lien prohibited hereby shall not be paid in full or
discharged, or in the event that the Borrower shall fail to perform or comply
with any other covenant, promise or obligation to the Banks hereunder or under
any Facility Document, the Banks may, but shall not be required to, perform,
pay, satisfy, discharge or bond the same for the account of such Borrower, and
all monies so paid by the Banks, including reasonable attorneys' fees, shall be
treated as an advance to the Borrower.

            (c) For all purposes contained in this Section 13.15, the
obligations referenced herein shall be deemed obligations of and applicable to
the Borrower and each of the Guarantors, and the Borrower shall cause each of
the Guarantors to comply with or perform all such obligations.

            Section 13.16  Relief from Bankruptcy Stay. The Borrower agrees
                           ---------------------------
that, in the event that such Borrower, any Guarantor or any of the persons or
parties constituting the Borrower or a Guarantor shall (i) file with any
bankruptcy court of competent jurisdiction or be the subject of any petition
under Title 11 of the U.S. Code, as amended ("Bankruptcy Code"), (ii) be the
subject of any order for relief issued under the Bankruptcy Code, (iii) file or
be the subject of any petition seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution, or similar relief under any
present or future federal or state act or law relating to bankruptcy,
insolvency, or other relief for debtors, (iv) have sought or consented to or
acquiesced in the appointment of any trustee, receiver, conservator, or
liquidator, or (v) be the subject of any order, judgment, or decree entered by
any court of competent jurisdiction approving a petition filed against such
readjustment, liquidation, dissolution, or similar relief under any present or
future federal or state act or law relating to bankruptcy, insolvency, or relief
for debtors, the Banks shall thereupon be entitled and the Borrower irrevocably
consents to immediate and unconditional relief from automatic stay by Section
362 of the Bankruptcy Code, or otherwise available to the Banks as provided for
herein, in the Notes, other Facility Documents delivered in connection herewith
and as otherwise provided by law, and the Borrower hereby irrevocably waives any
right to object to such relief and will not contest any motion by the Banks
seeking relief from the automatic stay and the Borrower will cooperate with the
Banks, in any manner requested by the Banks, in their efforts to obtain relief
from any such stay or other prohibition.
