     2.7   PAYMENT OF INTEREST. The Borrower promises and agrees to pay interest
on the outstanding principal balance of Advances in arrears on the last day of
each calendar month commencing with the first such day to occur after the date
of this Agreement. If interest is not paid when due, it may, without waiving any
default occasioned by such nonpayment, be added to principal and thereafter bear
like interest.

     2.8   PREPAYMENT. The Borrower may prepay any Variable Rate Advance in
whole or in part, at any time and without penalty, provided, however, that any
partial prepayment shall first be applied at the Bank's option, to accrued and
unpaid interest and next to the outstanding principal balance. The Borrower may
not voluntarily prepay a COF Advance or a LIBOR Advance other that on the last
day of the LIBOR Interest Period or COF Interest Period pertaining to such
Advance. If the whole or any part of any LIBOR Advance or COF Advance is prepaid
by reason of acceleration or pursuant to 2.10 below or as otherwise required by
this Agreement, the Borrower shall, upon the Bank's request, promptly pay to and
indemnify the Bank for all costs, expenses and any loss (including loss of
future interest income) actually incurred by the Bank and any loss (including
loss of profit resulting from the re-employment of funds) deemed sustained by
the Bank as a consequence of such prepayment. The Bank shall be entitled to fund
all or any portion of its Advances in any manner it may determine in its sole
discretion, but all calculations and transactions hereunder shall be conducted
as though the Bank actually funded all Advances through the purchase of dollar
deposits bearing interest at the same rate as U.S. Treasury securities in the
amount of the relevant Advance and in maturities corresponding to (a) the then
applicable Interest Period (b) the date of such purchase to the Expiration Date
hereunder.

     2.9   INDEMNIFICATION FOR LIBOR RATE OR COF COSTS. During any period of
time in which interest on any Advance is accruing on the basis of the LIBOR
Rate or COF Rate, the Borrower shall, upon the Bank's request, promptly pay to
and reimburse the Bank for all costs incurred and payments made by the Bank by
reason of any future assessment, reserve, deposit or similar requirement or any
surcharge, tax or fee imposed upon the Bank as a result of the Bank's compliance
with any directive or requirement of any regulatory authority pertaining or
relating to funds used by the Bank in quoting and determining the LIBOR Rate or
COF Rate.

     2.10. CONVERSION FROM LIBOR RATE OR COF RATE TO VARIABLE RATE. In the event
that the Bank shall at any time determine that the accrual of interest on the
basis of the LIBOR Rate or COF Rate (a) has become infeasible because the Bank
is unable to determine the LIBOR Rate or COF Rate due to the unavailability of
U.S. Dollar deposits, contracts or certificates of deposit in an amount
approximately equal to the amount of the relevant Advance and for a period of
time approximately equal to the relevant LIBOR Interest Period or Interest
Period as the case may be or (b) is or has become unlawful by reason of the
Bank's compliance with any new law, rule, regulation, guideline or order, or any
new interpretation of any present law, rule, regulation guideline or order, then
the Bank shall promptly give telephonic notice thereof (confirmed in writing) to
the Borrower, in which event any Advance bearing interest at the LIBOR Rate or
COF Rate as the case may be shall be deemed to be a Variable Rate Advance and
interest shall thereupon immediately accrue at the Variable Rate and shall
continue at such rate until the Bank determines that the LIBOR Rate or COF Rate
is no longer infeasible or unlawful.

                          1998 CREDIT AGREEMENT-Page 6
<PAGE>   7
     2.11 LINE ACCOUNT. The Bank shall maintain on its books a record of
account in which the Bank shall make entries for each Advance and such other
debits and credits as shall be appropriate in connection with the Line of
Credit (the "Line Account"). The Bank shall provide the Borrower with a monthly
statement of the Borrower's Line Account upon the Borrower's request therefor
from time to time, which statement shall be considered to be correct and
conclusively binding on the Borrower unless the Borrower notifies the Bank to
the contrary within 30 days after the Borrower's receipt of any such statement
which it deems to be incorrect.

     2.12 LATE PAYMENT. In addition to any other rights the Bank may hereunder,
if any payment of principal (other than a principal payment due pursuant to
Section 2.3) or interest, or any portion thereof, under this Agreement is not
paid when due, a late payment charge equal to five percent (5%) of such past
due payment may be assessed and shall be immediately payable.

of Credit.

Bank for Drawings shall be absolute, irrevocable, and unconditional under any
and all circumstances whatsoever and irrespective of any set-off, counterclaim
or defense to payment which the Borrower may have or have had against the Bank
(except such as may arise out of the Bank's gross negligence or willful
misconduct) or any other person, including, without limitation, and set-off,
counterclaim or defense based upon or arising out of:

          (a)  any lack of validity or enforceability of this Agreement or any
of the other Loan Documents;


                          1998 CREDIT AGREEMENT-Page 7
<PAGE>   8

            (b)   any amendment or waiver of or consent to departure from the
terms of any Letter of Credit;

            (c)   the existence of any claim, set-off, defense or other right
which the Borrower or any other person may have at any time against any
beneficiary or any transferee of any Letter of Credit (or any person for whom
any such beneficiary or any such transferee may be acting); or

            (d)   any allegation that any demand, statement or any other
document presented under any Letter of Credit is forged, fraudulent, invalid or
insufficient in any respect, or any statement therein being untrue or inaccurate
in any respect whatsoever or any variations in punctuation, capitalization,
spelling or format of the drafts or any statements presented in connecting with
any Drawing.

      3.4   RELEASE OF DOCUMENTS. The Bank shall not be obligated to release
any documents accompanying a Drawing under a Sight Credit until such time as
the Borrower has paid the full amount of such Drawing. No past or future custom
or practice of releasing documents prior to receiving such payment shall
operate as a waiver of the Bank's right under this Subsection. From and after
the occurrence of an Event of Default and until such time as such Event of
Default has been cured or waived, the Bank shall not be obligated to release
documents accompanying a Drawing under any Usance Credit until such time as

4.    FX TRANSACTIONS

      4.1   FOREIGN EXCHANGE FACILITY. The Bank agrees, as the Borrower's
request, to enter into FX Transactions with the Borrower from time to time
prior to the Expiration Date, provided that, at no time shall the aggregate FX
Risk Liability exceed $375,000.00 subject, however, to the further limitations
of Section 5.1.

      4.2   REQUESTS FOR FX TRANSACTIONS. Each request for a FX Transaction
shall be made by telephone to the Bank's Treasury Department (each a "Request")
and may be confirmed in writing to the address specified in Section 10.5 below,
shall specify the currency to be purchased or sold, the amount of such currency
and the settlement date. Each Request shall be delivered or communicated to the
Bank no later than 3:00 p.m. (California time) on the day (which shall be a
Business Day) on which the FX Transaction is requested. By making any such
Request, Borrower agrees that all matters relating to each such FX Transaction
shall be governed by this Agreement and Borrower restates all warranties and
representations made by Borrower herein as if made on the date the FX
Transaction is entered into.

      4.3   EXPIRATION DATE. The commitment by the Bank to enter into FX
Transactions shall, unless earlier terminated in accordance with this
Agreement, automatically terminate on the Expiration Date and no FX Transaction
shall expire on a date which is more than 90 days after the Expiration Date.

      4.4   TENOR. No FX Transaction shall have a Settlement Date which is more
than 90 days after the Expiration Date.

      4.5   AVAILABILITY. Bank may refuse to enter into a FX Transaction with
the Borrower where the Bank, in its sole discretion, determines that the
requested Foreign Currency is unavailable, if the Bank is not then dealing in
the requested Foreign Currency, or where Bank would be prohibited by any
applicable law, regulation or order from purchasing such Foreign Currency.

      4.6   PURPOSE. The FX Transaction shall be used to hedge the Borrower's
foreign exchange exposure and/or risk and not for purposes of speculation.

      4.7   PAYMENT. Payment is due on the Settlement Date of the respective FX
Transaction. Bank is hereby authorized by Borrower to charge the full
settlement price of any FX Transaction against the depository account or
accounts maintained by the Borrower with Bank on the Settlement Date. In the
event that Borrower fails to pay the settlement price of any Foreign Exchange
Contract on the relevant Payment Date, or the balances in the depository
account or accounts maintained by the Borrower with Bank are insufficient to
pay the settlement price on the Payment Date, without limiting the rights of
Bank under the Agreement or this Addendum or waiving any Event of Default
caused thereby, Bank may, and Borrower hereby authorizes Bank to create an
Advance bearing interest at the rate provided in the Agreement to pay the
settlement price on the Settlement Date.

      4.8   REMEDIES ON DEFAULT. Upon the occurrence of any Event of Default,
the Bank, may, at its sole and absolute discretion, without demand and only
upon such notice as may be required by law; 


                          1998 CREDIT AGREEMENT-Page 8
<PAGE>   9

            (a)   CLOSE-OUT AND LIQUIDATION. The Bank shall have the right to
close-out and liquidate all, but not less than all, the outstanding FX
Transactions (except to the extent that, in the good faith opinion of the Bank,
certain FX Transactions may not be closed-out and liquidated under applicable
law) in the following manner:

                  (1)   Close-out and liquidation shall be effected by
closing-out each outstanding FX Transaction (including any FX Transaction which
has not been performed and in respect of which the Settlement Date is on or
proceeds the Close-Out Date) so that each FX Transaction is canceled. The Bank
shall then calculate, in good faith, as of the value of each such canceled FX
Transaction (the "Closing Value") by converting:

                        (A)   in the case of an FX Transaction whose Settlement
Date is the same as or later than the Close-Out Date, the amount of the Foreign
Currency into U.S. Dollars at a rate of exchange at which the Bank can buy or
sell, as appropriate, U.S. Dollars with or against the Foreign Currency for
delivery on the Settlement Date of the respective FX Transaction, or

                        (B)   in the case of an FX Transaction whose Settlement
Date precedes the Close-Out Date, converting the amount of the Foreign
Currency, adjusted by adding interest with respect thereto at the Variable
Interest Rate from the Settlement Date to the Close-Out Date, into U.S. Dollars
at a rate of exchange at which the Bank can buy or sell, as appropriate, U.S.
Dollars with or against the Foreign Currency for delivery on the Close-Out Date;

                  (2)   With respect to a FX Transaction pursuant to which the
Bank agreed to purchase a Foreign Currency from the Borrower, the amount by
which the Closing Value as so determined exceeds the Notional Value is a
Closing Loss and the amount by which the Closing Value as so determined is less
than the Notional Value is a Closing Gain.

                  (3)   With respect to a FX Transaction pursuant to which the
Bank agreed to sell a Foreign Currency to the Borrower, the amount by which the
Closing Value as so determined exceeds the Notional Value is Closing Gain and
the amount by which the Closing Value as so determined is less than the
Notional Value a Closing Loss.

                  (4)   To the extent permitted by applicable law, the Closing
Gain or Closing Loss, as the case may be, for each Settlement Date falling after
the Close-Out Date will be adjusted (discounted) to its net present value (the
calculation of the amount of such adjustment shall be made by the Bank and
shall be conclusive as between the parties).

                  (5)   To the extent the net amount of Closing Gains exceeds
Closing Losses, such amount shall be payable by the Bank to the Borrower. To
the extent the net amount of Closing Losses exceeds Closing Gains, such amount
shall be payable by Borrower. In the case of the latter, the Borrower promises
and agrees to pay interest on the amount so payable from the Close-Out Date
until paid at the Variable Rate.

            (b)   TERMINATION. Terminate any future obligation of the Bank with
respect to FX Transactions, without affecting the Borrower's obligations to the
Bank or the Bank's rights and remedies under this Agreement.

            (c)   RECORDING. Borrower agrees and consents that the Bank may
(but will not be required to) record mechanically by tape recorder or other
such device all telephonic communications between the Borrower, its officers,
employees or authorized representatives and the Bank with respect to FX
Transactions and that the Bank may retain the recordings for such periods as it
deems advisable. Any such recording shall be conclusive as to the substance of
such communications.

5.    GENERAL LOAN TERMS

      5.1   MAXIMUM CREDIT. The Bank shall not be under any obligation to make
