applicable Interest Period shall be deemed to be a request for an Interest
Period of one month and each request for a Eurodollar Loan made when such Loans
are not available shall be deemed to be a request for an Alternate Base Rate
Loan; and

Period of the Revolving Credit Loan or payment, as the case may be. Failure to

otherwise affect the obligation of the Borrower hereunder or under the Revolving
Credit Note with respect to such Revolving Credit Loan, and any payment of
principal on the Revolving Credit Note by the Borrower shall not be affected by
the failure to make a notation thereof on said schedule.

Bank in connection with any change to such Statutory Reserves. It is agreed
that, for purposes of this paragraph, the Eurodollar Loans made hereunder shall
be deemed to constitute Eurocurrency Liabilities as defined in Regulation D and
to be subject to the reserve requirements of Regulation D without benefit or
credit of proration, exemptions or offsets which might otherwise be available to
the Bank from time to time under Regulation D.

      SECTION 2.12. Increased Costs. If, after the date of this Agreement, the
adoption of, or any change in, any applicable law, regulation, rule or
directive, or any interpretation thereof by any authority charged with the
administration or interpretation thereof:

            (i) subjects the Bank to any tax with respect to its Commitment, the
Loans, the Note or on any amount paid or to be paid 


                                     - 50 -
<PAGE>

under or pursuant to this Agreement, the Commitment, the Loans or the Note
(other than any tax measured by or based upon the overall net income of the
Bank);

            (ii) changes the basis of taxation of payments to the Bank of any
amounts payable hereunder (other than any tax measured by or based upon the
overall net income of the Bank);

            (iii) imposes, modifies or deems applicable any reserve, capital
adequacy or deposit requirements against any assets held by, deposits with or
for the account of, or loans made by, the Bank; or


                                     - 51 -
<PAGE>

            (iv) imposes on the Bank any other condition affecting its
Commitment, the Loans, the Note or this Agreement; and the result of any of the
foregoing is to increase the cost to the Bank of maintaining this Agreement or
the Commitment or making the Loans, or to reduce the amount of any payment
(whether of principal, interest or otherwise) receivable by the Bank or to
require the Bank to make any payment on or calculated by reference to the gross
amount of any sum received by it, in each case by an amount which the Bank in
its reasonable judgment deems material, then and in any such case:

            (a) the Bank shall promptly advise the Borrower of such event,
      together with the date thereof, the amount of such increased cost or
      reduction or payment and the way in which such amount has been calculated;
      and

            (b) the Borrower shall pay to the Bank, within ten (10) days after
      the advice referred to in subsection (a) hereinabove, such an amount or
      amounts as will compensate the Bank for such additional cost, reduction or
      payment for so long as the same shall remain in effect.

            The determination of the Bank as to additional amounts payable
pursuant to this Section 2.12 shall be conclusive evidence of such amounts
absent manifest error.

      SECTION 2.13. Capital Adequacy. If the Bank shall have determined that the
applicability of any law, rule, regulation or guideline, or the adoption after
the date hereof of any other law, rule, regulation or guideline regarding
capital adequacy, or any change in any of the foregoing or in the interpretation
or administration of any of the foregoing by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Bank (or any lending office of the Bank) or the
Bank's holding company 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 or would have the effect of reducing the rate of return
on the Bank's capital or on the capital of the Bank's holding company, if any,
as a consequence of its obligations hereunder to a level below that which the
Bank or the Bank's holding company could have achieved but for such adoption,
change or compliance (taking into consideration the Bank's policies and the
policies of the Bank's holding company with respect to capital adequacy) by an
amount reasonably deemed by the Bank to be material, then and in any such case:

            (a) the Bank shall promptly advise the Borrower of such event,
      together with the date thereof, the amount of such reduction and the way
      in which such amount has been calculated; and


                                     - 53 -
<PAGE>

            (b) the Borrower shall pay to the Bank, within ten (10) days after
      the advice referred to in subsection (a) hereinabove, such an amount or
      amounts as will compensate the Bank for such reduction for so long as the
      same shall remain in effect.

            The determination of the Bank as to additional amounts payable
pursuant to this Section 2.13 shall be conclusive evidence of such amounts
absent manifest error.

      SECTION 2.14. Change in Legality. (a) Notwithstanding anything to the
contrary contained elsewhere in this Agreement, if any change after the date
hereof in law, rule, regulation, guideline or order, or in the interpretation
thereof by any governmental authority charged with the administration thereof,
shall make it unlawful for the Bank to make or maintain any Eurodollar Loan or
to give effect to its obligations as contemplated hereby with respect to a
Eurodollar Loan, then, by written notice to the Borrower, the Bank may:

            (i) declare that Eurodollar Loans will not thereafter be made
      hereunder, whereupon the Borrower shall be prohibited from requesting such
      Eurodollar Loans hereunder unless such declaration is subsequently
      withdrawn; and

           (ii) require that, subject to the provisions of Section 2.10, all
      outstanding Eurodollar Loans made by it be converted to an Alternate Base
      Rate Loan, whereupon all of such Eurodollar Loans shall be automatically
      converted to an 


                                     - 54 -
<PAGE>

      Alternate Base Rate Loan as of the effective date of such notice as
      provided in paragraph (b) below.

            (b) For purposes of this Section 2.14, a notice to the Borrower by
the Bank pursuant to paragraph (a) above shall be effective, for the purposes of
paragraph (a) above, if lawful, and if any Eurodollar Loans shall then be
outstanding, on the last day of the then current Interest Period; otherwise,
such notice shall be effective on the date of receipt by the Borrower.


                                     - 55 -

      SECTION 2.15. Indemnity. The Borrower will indemnify the Bank against any
loss or expense which the Bank may sustain or incur as a consequence of any
default in payment or prepayment of the principal amount of any Eurodollar Loan
or any part thereof or interest accrued thereon, as and when due and payable (at
the due date thereof, by notice of prepayment or otherwise), or the occurrence
of any Event of Default, including but not limited to any loss or expense
sustained or incurred in liquidating or employing deposits from third parties
acquired to affect or maintain such Eurodollar Loan or any part thereof. When
claiming under this Section 2.15, the Bank shall provide to the Borrower a
statement, signed by an officer of the Bank, explaining the amount of any such
loss or expense (including the calculation of such amount), which statement
shall, in the absence of manifest error, be conclusive with respect to the
parties hereto.

<PAGE>

      SECTION 2.16. Change in LIBOR; Availability of Rates. In the event, and on
each occasion, that, on the day the interest rate for any Eurodollar Loan is to
be determined, the Bank shall have reasonably determined (which determination,
absent manifest error, shall be conclusive and binding upon the Borrower) that
dollar deposits in the amount of the principal amount of the requested
Eurodollar Loan are not generally available in the London interbank market, or
that the rate at which such dollar deposits are being offered will not
adequately and fairly reflect the cost to the Bank of making or maintaining the
principal amount of such Eurodollar Loan during such Interest Period, such
Eurodollar Loan shall be unavailable. The Bank shall, as soon as practicable
thereafter, given written, telex or telephonic notice of such determination of
unavailability to the Borrower. Any request by the Borrower for an unavailable
Eurodollar Loan shall be deemed to have been a request for an Alternate Base
Rate Loan. After such notice shall have been given and until the Bank shall have
notified the Borrower that the circumstances giving rise to such notice no
longer exist, each subsequent request for an unavailable Eurodollar Loan shall
be deemed to be a request for an Alternate Base Rate Loan.

      SECTION 2.17. Authorization to Debit Borrower's Account. The Bank is
hereby authorized to debit the Borrower's account maintained with the Bank for
(i) all scheduled payments of principal and/or interest under the Note, and (ii)
the commitment fee and all other amounts due hereunder; all such debits to be
made 


                                     - 57 -

      SECTION 2.18. Late Charges, Default Interest. (a) If the Borrower shall
default in the payment of any principal installment of or interest on any Loan
or any other amount becoming due hereunder, the Borrower shall pay interest, to
the extent permitted by law, on such defaulted amount up to the date of actual
payment (after as well as before judgment) at a rate per annum (computed on the
basis of the actual number of days elapsed over a year of 360 days) equal to (i)
the amount of principal, interest, fees and/or other amounts due (the "Past Due
Amount") times (ii) two (2%) percent in excess of the interest rate otherwise in
effect with respect to the type of Loan in connection with which the required
payments have not been made, or, if no such interest rate is in effect, two (2%)
percent in excess of the Alternate Base Rate, times (ii) the number of days the
Past Due Amount is delinquent.

      (b) Upon the occurrence and during the continuation of an Event of
Default, the Borrower shall pay interest on all amounts owing under the Note and
this Agreement (after as well as before judgment) at a rate per annum (computed
on the basis of the actual number of days elapsed over a year of 360 days) equal
to two (2%) percent in excess of the interest rate otherwise in effect
hereunder.

      SECTION 2.19. Payments. All payments by the Borrower hereunder or under
the Note shall be made in Dollars in immediately available funds at the office
of the Bank by 12:00 noon, New York City time on the date on which such payment
shall be due. Interest on the Note shall accrue from and including the date of
each Loan to but excluding the date on which such Loan is paid in full or
refinanced with a Loan of a different type.

      SECTION 2.20. Interest Adjustments. (a) If the provisions of this
Agreement or the Note would at any time otherwise require payment by the
Borrower to the Bank of any amount of interest in excess of the maximum amount
then permitted by applicable law the interest payments shall be reduced to the
extent necessary so that the Bank shall not receive interest in excess of such
maximum amount. To the extent that, pursuant to the foregoing sentence, the Bank
shall receive interest payments hereunder or under the Note in an amount less
than the amount otherwise provided, such deficit (hereinafter called the
"Interest Deficit") will cumulate and will be carried forward (without interest)
until the termination of this Agreement. Interest otherwise payable to the Bank
hereunder and under the Note for any subsequent period shall be increased by
such maximum amount of the Interest Deficit that may be so added without causing
the Bank to receive interest in excess of the maximum amount then permitted by
applicable law.

      (b) The amount of the Interest Deficit on the Maturity Date shall be
cancelled and not paid.

time, to sell, assign, transfer or negotiate all or any part of the Note or the
Commitment or grant participations therein to one or more banks (foreign or
domestic, including an affiliate of the Bank), insurance companies or other
financial institutions, pension funds or mutual funds, provided that (i) any
such sale, assignment, transfer or negotiation shall be with the consent of the
Borrower, such consent not to be unreasonably withheld or delayed and provided
further that the Borrower's consent shall not be required if any Default or
Event of Default has occurred and is continuing and (ii) as long as no Default
or Event of Default has occurred and is continuing, the Bank agrees to retain at
least fifty one (51%) percent of the Commitment and outstanding Loans. The
Borrower and the Guarantor agree and consent to the Bank providing financial and
other information regarding their business and operations to prospective
purchasers or participants (provided that such prospective purchasers or
participants shall agree in writing to be bound by the provisions of Section
7.09 hereof prior to receiving any information regarding the Borrower or any of
its Subsidiaries) and further agree that to the extent that the Bank should
sell, assign, transfer or negotiate all or any part of the Note or the
Commitment, the Bank shall be forever released and discharged from its
obligations under the

      Note, the Commitment and this Agreement to the extent same is sold,

                         REPRESENTATIONS AND WARRANTIES

      SECTION 4.01. Representations and Warranties. On the date hereof and, on
each date that the Borrower requests a Revolving Credit Loan, the Borrower and
the Guarantor each represent and warrant as follows:

      (a) Subsidiaries. On the date hereof, the only Subsidiaries of the
Borrower or the Guarantor are those set forth on Schedule 4.01(a) annexed
hereto, which Schedule accurately sets forth with respect to each such
Subsidiary, its name and address, any other addresses at which it conducts
business, its state of incorporation and each other jurisdiction in which it is
qualified to do business and the identity and share holdings of its
stockholders. Except as set forth on Schedule 4.01(a), all of the issued and
outstanding shares of each Subsidiary which are owned by the Borrower or the
Guarantor are owned by the Borrower or the Guarantor free and clear of any
mortgage, pledge, lien or encumbrance, other than Liens permitted by Section
5.02(a) of this Agreement. Except as set forth on Schedule 4.01(a) and except
for options granted under the 1984 Stock Option Plan or the 1994 Stock Plan,

      (b) Organization; Good Standing. The Borrower, the Guarantor and each
Subsidiary of the Borrower or the Guarantor are each a corporation duly
incorporated, validly existing and in good standing under the laws of their
respective jurisdictions of incorporation and each has the corporate power to
own its assets and to transact the business in which it is presently engaged and
is duly qualified and is in good standing in all other jurisdictions where the
failure to so qualify would be reasonably likely to result in a Material Adverse
Change.

      (c) Loan Documents; No Consents or Violations. The execution, delivery and
performance by the Borrower and the Guarantor of the Loan Documents to which
they are a party are within the Borrower's and the Guarantor's corporate power
and have been duly authorized by all necessary corporate action and do not and
will not (i) require any consent or approval of the stockholders of the Borrower
or the Guarantor (other than those previously obtained and appropriate evidence
of which has been delivered to the Bank); (ii) do not contravene the Borrower's
or the Guarantor's certificate of incorporation, charter or by-laws; (iii)
violate any provision of or any law, rule, regulation, contractual restriction,

any other material agreement, lease or instrument to which the Borrower or the
Guarantor is a party or by which it or its properties may be bound or affected;
and (v) result in, or require, the creation or imposition of any Lien upon or
with respect to any of the properties now owned or hereafter acquired by the
Borrower or the Guarantor.

      (d) Authorization. No authorization or approval or other action by, and no
notice to or filing with, any governmental authority or regulatory body is
required for the due execution, delivery and performance by the Borrower or the
Guarantor of any Loan Document to which it is a party, except authorizations,
approvals, actions, notices or filings which have been obtained, taken or made,
as the case may be.

      (e) Validity and Enforceability. The Loan Documents, when delivered
hereunder, will have been duly executed and delivered on behalf of the Borrower
and the Guarantor, as the case may be, and will be legal, valid and binding
obligations of the Borrower and the Guarantor, as the case may be, enforceable
against the Borrower or the Guarantor in accordance with their respective terms.

<PAGE>

extensions of credit (including agreements and arrangements for the issuance of

and any such Subsidiary of such reprogramming and testing and of the reasonably
foreseeable consequences of year 2000 to the Borrower and the Guarantor
(including, without limitation, reprogramming errors and the failure of others'
systems or equipment) will not result in a Default or be reasonably likely to
result in a Material Adverse Change in the Borrower or the Guarantor or any such
Subsidiary.

to continue for the term of this Agreement to be, sufficient to permit the
Borrower, the Guarantor and each such Subsidiary to conduct its business without
Material Adverse Change.

      Borrower hereby authorizes Bank to enter from time to time the amount of
each Loan to Borrower and the amount of each payment on a Loan on the schedule
annexed hereto and made a part hereof. Failure of Bank to record such

any such action or proceeding. Borrower hereby submits to the jurisdiction of
the Supreme Court of the State of New York and agrees with Bank that personal
jurisdiction over Borrower shall rest with the Supreme Court of the State of New
York for purposes of any action on or related to this Note, the liabilities
hereunder, or the enforcement of either or all of the same. Borrower hereby
waives personal service by manual delivery and agrees that service of process
may be made by pre-paid certified mail directed to the Borrower at the
Borrower's address set forth above or at such other address as may be designated
in writing by the Borrower to Bank in accordance with Section 7.02 of the

the same effect as though personally served. Borrower hereby expressly waives
any and every right to a trial by jury in any action on or related to this Note,
the liabilities hereunder or the enforcement of either or all of the same.

      Subject to the provisions of the Agreement, Bank may transfer this Note to
the permitted transferee or transferees, who shall thereupon become vested with
all the powers and rights above given to Bank in respect thereto, and Bank shall
thereafter be forever relieved and fully discharged from any liability or
responsibility in the matter. The failure of any holder of this Note to insist


                                    - 125 -

upon strict performance of each and/or all of the terms and conditions hereof
