                thereof to Executive, or (b) the commission by Executive of any
                act resulting in or intending to result in his personal gain or
                enrichment at the expense of the Company, or the commission by
                Executive of any felony or misdemeanor or act involving moral
                turpitude.
             d. By the Company without cause, in which case Executive shall be
                entitled to an amount equal to twelve (12) months of his Base
                Salary in effect at the time of termination, payable in salary
                continuation or lump sum in accordance with Company practice.
             e. By the executive if, at any time during the term as a result of
                a change in control of the Company shall have occurred, in which
                case Executive shall be entitled to an amount equal to twelve
                (12) months of his Base Salary in effect at the time of
                termination plus a pro-rata portion of his Incentive Bonus at
                target for the period of the beginning of the fiscal year
                through date of termination, payable in salary continuation or
                lump sum in accordance with Company practice. For the purpose of
                the foregoing, a change in control shall occur in the

<PAGE>   2
                 event the Company enters into any agreement involving the sale
                 of a controlling interest in the Company or the sale by the
                 company of all or substantially all of its assets to any other
                 entity, or the merger of the Company into and with another
                 entity in which the Company is not the survivor, or in which
                 the Company is not the controlling shareholder. In the event
                 of termination by Executive under this subparagraph, Executive
                 shall be entitled to receive, as a special severance benefit,
                 all options granted to Executive and which shall not have
                 heretofore vested, shall immediately vest and become presently
                 exercisable.

         which such interest or fees are payable (to the extent computed on the
         basis of days elapsed).

         SECTION 2.9. INTEREST RATE NOT ASCERTAINABLE, ETC.

         In the event that the Lender shall have determined (which determination
shall be made in good faith and, absent manifest error, shall be final,
conclusive and binding upon all parties) that on any date for determining the
Applicable Rate for any Interest Period, by reason of any changes arising after
the date of this Agreement affecting the London interbank market, or the
Lender's position in such market, adequate and fair means do not exist for
ascertaining the Applicable Rate, then, and in any such event, the Lender shall
forthwith give notice (by telephone confirmed in writing) to Borrower of such
determination and a summary of the basis for such determination. Until the
Lender notifies Borrower that the circumstances giving rise to the suspension
described herein no longer exist, the obligations of the Lender to make or
permit portions of the Revolving Credit Note to remain outstanding past the last
day of the then current Interest Periods shall be suspended, and such affected
Advances shall bear the same interest as Lender's Base Rate.

         determination shall be made in good faith and, absent manifest error,
         shall be final, conclusive and binding upon all parties) at any time
         that the making or continuance of any Advance at the Applicable Rate
         has become unlawful by compliance by the Lender in good faith with any
         applicable law, governmental rule, regulation, guideline or order
         (whether or not having the force of law and whether or not failure to
         comply therewith would be unlawful), then, in any such event, the
         Lender shall give prompt notice (by telephone confirmed in writing) to
         Borrower of such determination and a summary of the basis for such
         determination.

                  (b) Upon the giving of the notice to Borrower referred to in
         subsection (a) above, Borrower's right to request and the Lender's
         obligation to make Advances at the Applicable Rate shall be immediately
         suspended, and the Applicable Rate shall become the Base Rate.

                  Rate, or its obligation to make such Advances, or the basis of
                  taxation of payments to the Lender of the principal of or
                  interest on the Advances or its obligation to make Advances
                  shall have changed (except for changes in the tax on the
                  overall net income of the Lender imposed by the jurisdiction
                  in which the Lender's principal executive office or Lending
                  Office is located); or

                           (ii) any reserve (including, without limitation, any
                  imposed by the Board of Governors of the Federal Reserve
                  System), special deposit or similar requirement against assets
                  of, deposits with or for the account of, or credit extended

                  Office or the London interbank market;

         and as a result thereof there shall be any increase in the cost to the
         Lender of agreeing to make or making, funding or maintaining Advances
         at the Applicable Rate or its obligation to make Advances at the
         Applicable Rate, then Borrower shall from time to time upon written
         notice from and demand by the Lender to Borrower, pay to the Lender
         within ten (10) Business Days after the date of such notice and demand,
         additional amounts sufficient to indemnify the Lender against such
         increased cost. A certificate as to the amount of such increased cost,
         submitted to Borrower by the Lender in good faith and accompanied by a
         statement prepared by the Lender describing in reasonable detail the
         basis for and calculation of such increased cost, shall, except for
         manifest error, be final, conclusive and binding for all purposes.

         Borrower shall compensate the Lender, upon its written request to
Borrower (which request shall set forth the basis for requesting such amounts in
reasonable detail and which request shall be made in good faith and, absent
manifest error, shall be final, conclusive and binding upon all of the parties
hereto), for all actual losses, expenses and liabilities (including, without
limitation, any interest paid by the Lender to lenders of funds borrowed by it
to make or carry its Advances at the

                                       14
<PAGE>   17

Applicable Rate, in either case to the extent not recovered by the Lender in
connection with the re-employment of such funds but excluding loss of
anticipated profits), which the Lender may sustain: (i) if for any reason (other
than a default by the Lender) a borrowing of or continuation of Advances to
Borrower does not occur on the date specified therefor in a Notice of Borrowing
or subsequent continuation thereof (whether or not withdrawn), (ii) if any
repayment of any Advances to Borrower occurs on a date which is not the last day
of an Interest Period applicable thereto, or (iii), if, for any reason, Borrower
defaults in its obligation to repay its Advances when required by the terms of
this Agreement.

         SECTION 2.13. ASSUMPTIONS CONCERNING FUNDING OF EURODOLLAR ADVANCES.

         Calculation of all amounts payable to the Lender under this Article 2.
shall be made as though the Lender had actually funded the Advance through the
purchase of deposits in the relevant market bearing interest at the rate
applicable to such Advance in an amount equal to the amount of the Advance and
having a maturity comparable to the relevant Interest Period and through the
transfer of such Advance from an offshore office of the Lender to a domestic
office of the Lender in the United States of America; provided, however that
each Lender may fund each Advance in any manner it sees fit and the foregoing

restated or modified (the "CREDIT AGREEMENT"). TERMS NOT OTHERWISE DEFINED
HEREIN SHALL HAVE THE SAME MEANING AS IN THE CREDIT AGREEMENT.

         The Borrower agrees to make payments of principal and interest on the
Advances hereunder on the dates and in the amounts specified in the Credit
Agreement. This Revolving Credit Note shall mature on January 4, 2002 (the
"Maturity Date"), at which time the Borrower shall pay to the Lender an amount
equal to all outstanding principal, plus all accrued and unpaid interest.

         Until maturity and provided no Default or Event of Default has occurred
hereunder, the Borrower may borrow, repay, and reborrow hereunder.

         Lender and Borrower intend to conform strictly to applicable usury laws
as presently in effect. Accordingly, Borrower and Lender agree that,
notwithstanding anything to the contrary herein or in any agreement executed in
connection with or as security for this Note, the sum of all consideration that
constitutes interest under applicable law which is contracted for, charged, or
received hereunder shall under no circumstance, including without limitation any
circumstance in which the Note has been accelerated or prepaid, exceed the
maximum lawful rate of interest permitted by applicable law. Any excess interest
shall be credited on this Note or, if this Note shall have been paid in full,
refunded to Borrower, by the holder hereof.

         Overdue principal and, to the extent not prohibited by applicable law,
overdue interest, in respect of the Advances, and all other overdue amounts
owing hereunder, shall bear interest from each date that such amounts are
overdue at a

rate of interest equal to the lesser of (i) 13% per annum or (ii) the maximum
lawful rate allowed by applicable law.

         TIME IS OF THE ESSENCE OF THIS NOTE, WITH REGARDS TO EACH AND EVERY
PROVISION OF THIS NOTE.

         Upon the occurrence of (a) any breach of any promise made in this Note
or in any other document relating to, securing, or otherwise executed in
connection with this Note; or (b) upon the occurrence of an Event of Default as
defined in the Credit Agreement; then in any of such events (each for purposes
of this Note, an Event of Default), at the option of the holder, the entire
indebtedness hereby evidenced shall become due, payable and collectible then or
thereafter, without notice, as the holder may elect regardless of the date of
maturity. The holder may waive any default before or after the same has been
declared and restore this Note to full force and effect without impairing any
rights hereunder, such right of waiver being a continuing one.

         Borrower and any and all accommodation parties, endorsers, guarantors
and other parties liable on this Note, (collectively, the "OBLIGORS") jointly
and severally waive presentment for payment, protest, notice of protest, notice
of nonpayment of this Note, demand and all legal diligence in enforcing
collection, and any discharge or defenses based on suretyship or impairment of
collateral; and hereby expressly consent to (i) any and all delays, extensions,
renewals or other modifications of this Note or any waivers of any term hereof,
(ii) any release or discharge by Lender of any of the Obligors, (iii) any
release substitution or exchange of any security for the payment hereof, (iv)
any failure to act on the part of Lender, and (vi) any indulgence shown by
Lender from time to time (without notice or further assent from any of the
Obligors) and hereby agree that no such action, failure to act or failure to
exercise any right or remedy by Lender shall in any way affect or impair the
obligations of any of the Obligors.

         BORROWER HEREBY KNOWINGLY, WILLINGLY AND IRREVOCABLY WAIVES ITS RIGHTS
TO DEMAND A JURY TRIAL IN ANY ACTION OR PROCEEDING INVOLVING THIS NOTE OR ANY
DOCUMENTS EXECUTED OR DELIVERED IN CONNECTION HEREWITH OR ANY RELATIONSHIP
BETWEEN BORROWER AND LENDER.

         In any action to enforce this Note, Borrower hereby irrevocably and
unconditionally waives any and all rights under the laws of any state to claim
or recover any special, exemplary, punitive, consequential or other damages
other than actual direct damages.

         Borrower shall pay, on demand, all costs and expenses (including court
costs, attorneys' fees and expenses) incurred by Lender in attempting to enforce
or collect this Note, protect or enforce its rights under this Note, or protect
or collect on any security for the payment of this Note.
