which at all times is equal to the Prime Rate, said rate to change when and as

of principal. Interest on all Loans shall be computed using a per diem rate
which shall be a fraction, the numerator of which shall be the rate of interest
calculated in accordance with Section 1.5(A) or (B) above and the denominator of
which shall be three hundred sixty (360), multiplied by the actual number of
days elapsed. For the purposes of computing interest earned on the Loans,
including without limitation interest payments which are paid by an Advance (in
which case such advance shall constitute a Loan) or interest payments which are
withdrawn directly from Borrowers' accounts maintained with Lender or are made
by other current funds (AND EACH BORROWER HEREBY CONSENTS TO ANY AND ALL SUCH
ADVANCES AND/OR WITHDRAWALS, AND/OR PAYMENTS BY ANY OTHER MEANS AVAILED OF BY
LENDER, AND FURTHER CONSENTS TO PAYMENTS OF PRINCIPAL AND/OR INTEREST ON ANY OF
THE LOANS AND/OR OTHER SUM OWING TO LENDER BY SUCH ADVANCES AND/OR WITHDRAWALS),
credit for checks deposited, wire transfers received or payment by any other
means shall be given on the third (3rd) business day following the receipt of
such check, wire transfer or other form of payment. In the event any payment of
principal and/or interest shall be returned unpaid for any reason, any credit
given on account of such payment shall be deleted, interest shall accrue
retroactively to the date such credit was given and such payment shall be deemed
for all purposes under this Agreement, never to have been made. Any interest not
paid as aforesaid may, in Lender's sole discretion, accrue and be added to the
principal and continue to bear interest at the rate being borne by such
principal

                  1.7 Prepayment. Any amounts outstanding bearing interest at
the LIBOR Rate may only be prepaid if any such prepayment is accompanied by the
Prepayment Premium.

         SECTION 6. SET-OFF RIGHTS.

and not by way of limitation of any such rights, each Lender and any affiliate
of Lender is hereby authorized by Borrower and the Guarantor at any time or from
time to time, without notice to Borrower or to any other Person, any such notice
being hereby expressly waived by Borrower and Guarantor to set off and to
appropriate and to apply any and all balances, deposits, credits, Collateral and
property of Borrower held at, or in transit to, any of its offices for the
account of Borrower and/or Guarantor (regardless of whether then due to Borrower
and/or Guarantor) and any other property at any time held or in transit or owing
by that Lender or that holder to or for the credit or for the account of
Borrower or Guarantor against and on account of any of the Loans which remain
unpaid. Borrower and Guarantor agree, to the fullest extent permitted by law,
that (a) Lender or any holder may exercise its right to set off with respect to
the Loans and may sell participations in such set off to other lenders and
holders and (b) any lender or holder so purchasing a participation in the Loans
made or held by other lenders or holders may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Lender or holder were a direct holder of Loans in the amount
of such participation and (3) the rights contained in this paragraph exist
regardless of whether the Loan to which they are applied has matured.

its rights by suit in equity, action at law or other appropriate proceedings,
whether for the specific performance of any agreement contained herein or in any
other Document, or for an injunction against a violation of any of the terms
hereof or thereof, or in aid of the exercise of any right, power or remedy
granted thereby or by law, equity or otherwise.

                  7.2 Upon the occurrence of a Default or Event of Default the
Borrower grants a royalty-free license to the Lender for all patents, service
marks, trademarks, tradenames, copyrights, computer programs and other
intellectual property rights sufficient to permit the Lender to exercise all
rights granted to the Lender pursuant to this Agreement.

         SECTION 8.  CUMULATIVE REMEDIES; NO WAIVERS, ETC.

         No right, power or remedy granted to Lender in this Agreement or in the

addition to any other rights, powers


                                       24
<PAGE>
or remedies referred to in this Agreement, in the other Documents or otherwise
available to Lender at law or in equity; and the exercise or beginning of
exercise by Lender of any one or more of such rights, powers or remedies, shall
not preclude the simultaneous or later exercise by Lender of any or all of such
other rights, powers or remedies. No waiver by, nor any failure or delay on the
part of Lender in any one or more instances to insist upon strict performance or
observance of one or more covenants or conditions hereof, or of the other
Documents shall in any way be, or be construed to be, a waiver of such covenant
in any other instance or to prevent Lender's rights to later require the strict
performance or observance of such covenants or conditions, or otherwise
prejudice Lender's rights, powers or remedies.

         SECTION 9.  PARTIAL INVALIDITY; WAIVERS.

                  9.1 If any term or provision of this Agreement or any of the
other Documents or the application thereof to any Person or circumstance shall,
to any extent, be invalid or unenforceable by reason of any applicable law, the
remainder of this Agreement and the other Documents, or application of such term
or provision to Persons or circumstances other than those as to which it is held
invalid or unenforceable, shall not be affected thereby, and each term and
provision of this Agreement and the other Documents shall be valid and be
enforced to the fullest extent permitted by law. To the full extent, however,
that the provisions of any such applicable law may be waived, they are hereby
waived by Borrower to the end that this Agreement and the other Documents shall
be deemed to be valid and binding obligations enforceable in accordance with
their terms.

                  9.2 To the extent permitted by applicable law, Borrower and
Guarantor hereby waives protest, prior notice of protest, or dishonor, notice of
payments and non-payments, or of any default.

                  9.3 WITH RESPECT TO ANY CONTROVERSY, ACTION, PROCEEDING OR

REPOSSESSION OR SELF HELP AS MAY PRESENTLY EXIST UNDER STATUTE OR COMMON LAW.

                  9.5 BORROWER SPECIFICALLY WAIVES AND RELINQUISHES ANY CLAIM TO
INCIDENTAL AND/OR CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF AN ALLEGED

shall be repaid by Borrower on demand, together with interest thereon at the

accurately reflect the cost to Lender of making or maintaining LIBOR Advances
for the Interest Period or therefor, then Lender shall forthwith give notice
thereof to Borrower, whereupon, (1) the obligation of Lender to permit the LIBOR
Advances to bear interest at the LIBOR Rate shall be suspended so long as such
circumstances exist, and (2) Borrower shall convert the interest rates on the
applicable portions of the outstanding Advances to the rate in relation to the
PRIME RATE set forth above for the current Interest Period. Such suspension
shall continue until Lender notifies Borrower that the circumstances giving rise
to such suspension no longer exist.

any change in rules, or change in the interpretation or administration thereof,
by a governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender with any
request or directive (whether or not having the force of law) of any such
authority, central bank or comparable agency shall make it unlawful or
impossible for Lender to make or maintain or fund LIBOR Advances, the interest
rates on the applicable portions of the outstanding LIBOR Advances shall be
deemed to have been converted to the rate relating to the PRIME RATE set forth
above, on either (a) the last day of the then current Interest Period if Lender
may lawfully continue to maintain loans at the LIBOR Interest Rate to such day,
or (b) immediately if Lender may not lawfully continue to maintain Advances at
the LIBOR Interest Rate.

                  (iii) Upon notice to Borrower, the Borrower shall pay to the
Lender for the account of Lender, such amount or amounts as shall be sufficient
(in the reasonable opinion of Lender) to compensate it for any loss, cost,
liability or expense incurred as a result of (x) any repayment of a LIBOR
Advance on a date other than the last day of the Interest Period for such LIBOR
Advance, including, but not limited to that resulting from acceleration of all
amounts outstanding under any Loan following the occurrence of any Default or
Event of Default and/or (y) any failure by Borrower to borrow or convert or
prepay, as the case may be, a LIBOR Advance on the date for borrowing or
conversion or prepayment, as the case may be, which is specified in the Notice
of Interest Rate Election.

         NOTICE OF INTEREST RATE ELECTION: Whenever Borrower desires to elect,

Election in form provided by Lender and substance as that attached hereto as

Treasury (excluding those commonly known as "Flower Bonds") having a term

nearest in expiration of the relevant Interest Period. The maturity date and
yield to maturity of such United States Treasury obligation shall be determined
by Lender on the basis of quotations appearing in the Reuter Monitor Money Rates
Service or other repository service reasonably satisfactory to Lender on the
prepayment date. If there shall be more than one such debt obligation of the
United States Treasury maturing nearest in time to the expiration of the
relevant Interest Period, the Prepayment Yield to Maturity shall be the
arithmetic average of the yields to maturity of all such obligations. Said
prepayment shall be irrevocable once Borrower has notified Lender of such
prepayment and Borrower will reimburse Lender for any and all loss, cost,
