currency other than United States Dollars, Bank shall create a reserve under the
Committed Revolving Line for letters of credit against fluctuations in currency
exchange rates, in an amount equal to ten percent (10%) of the face amount of
such letter of credit. The amount of such reserve may be amended by Bank from

shall notify Bank in writing within five (5) days of the occurrence of any of
the following: (1) Borrower begins or consents in any manner to any proceeding
or arrangement for its liquidation in whole or in part or to any other

or a procedure therefor has been commenced against it.

     6.5    Payment in Dollars.  Borrower shall require payment in United States

     Any one or more of the following events with respect to either Borrower

interest on, any Advances when due and payable; or fails to pay any portion of
any other Obligations not constituting such principal or interest, including

the United States Bankruptcy Code, would have occurred on any accounts), within
thirty (30) days of receipt by Borrower of an invoice therefor;

     8.2    Covenant Default; Cross Default.  If Borrower fails or neglects to
            -------------------------------                                   
perform, keep, or observe any material term, provision, condition, covenant, or
agreement contained in this Exim Agreement, in any of the Domestic Loan
Documents, the Borrower Agreement or the Exim Loan Documents, or an Event of
Default  occurs under any of the Domestic Loan Documents or the Borrower
Agreement; or

     8.3    Exim Guarantee.  If the Exim Guarantee ceases for any reason to 
            -------------- 
be in full force and effect, or if the Exim Bank declares the Exim Guarantee
void or revokes or purports to revoke any obligations under the Exim Guarantee.

     9.     BANK'S RIGHTS AND REMEDIES
            --------------------------

     9.1    Rights and Remedies.  Upon the occurrence of an Event of Default, 
            -------------------    
Bank may, at its election, without notice and without demand, do any one or more
of the following:

            (a)    Declares all Obligations, whether evidenced by this Exim
     Agreement, or by any of the other Exim Loan Documents, immediately due and
     payable;

            (b)    Cease advancing money or extending credit to or for the
     benefit of Borrower under this Exim Agreement or under any other agreement
     between Borrower and Bank;

            (c)    Settle or adjust disputes and claims directly with account
     debtors for amounts, upon terms and in whatever order that Bank reasonably
     considers advisable;

            (d)    Notify customers of Borrower or other third parties to pay
     amounts owing to Borrower directly to the Bank;

            (e)    Without notice to or demand upon Borrower, make such payments
     and do such acts as Bank considers necessary or reasonable to protect its
     security interest in the Collateral. Borrower agrees to assemble the
     Collateral if Bank so requires, and to make the Collateral available to
     Bank as Bank may designate. Borrower authorizes Bank to enter the premises
     where the Collateral is located, to take and maintain possession of the
     Collateral, or any part of it, and to pay, purchase, contest, or compromise
     any encumbrance, charge, or lien which in Bank's determination appears to
     be prior or superior to its security interest and to pay all expenses
     incurred in connection therewith. With respect to any of Borrower's owned
     premises, Borrower hereby grants Bank a license to enter into possession of
     such premises and to occupy the same, without charge, in order to exercise
     any of Bank's rights or remedies provided herein, at law, in equity, or
     otherwise;

                                      -8-
<PAGE>
 
            (f)    Set off and apply to the Obligations any and all (i) balances
     and deposits of Borrower held by Bank, or (ii) indebtedness at any time
     owing to or for the credit or the account of Borrower held by Bank;

            (g)    Ship, reclaim, recover, store, finish, maintain, repair,
     prepare for sale, advertise for sale, and sell (in the manner provided for
     herein) the Collateral. Bank is hereby granted a license or other right,
     solely pursuant to the provisions of this Section 9.1, to use, without
     charge, Borrower's labels, patents, copyrights, rights of use of any name,
     trade secrets, trade names, trademarks, service marks, and advertising
     matter, or any property of a similar nature, as it pertains to the
     Collateral, in completing production of, advertising for sale, and selling
     any Collateral and, in connection with Bank's exercise of its rights under
     this Section 9.1, Borrower's rights under all licenses and all franchise
     agreements shall inure to Bank's benefit;

            (h)    Sell the Collateral at either a public or private sale, or
     both, by way of one or more contracts or transactions, for cash or on
     terms, in such manner and at such places (including Borrower's premises) as
     Bank determines is commercially reasonable;

            (i)    Bank may credit bid and purchase at any public sale; and

            (j)    Any deficiency that exists after disposition of the
     Collateral as provided above will be paid immediately by Borrower.

     9.2    Exim Direction.  Upon the occurrence of an Event of Default, 
            --------------    
Exim Bank shall have a right to: (i) direct Bank to exercise the remedies
specified in Section 9.1 and (ii) request that Bank accelerate the maturity of
any other loans to Borrower as to which Bank has a right to accelerate.

     9.3    Exim Notification.  Bank shall have the right to immediately notify
            -----------------                                                  
Exim Bank in writing if it has knowledge of the occurrence of any of the
following events: (1) any failure to pay any amount due under this Loan Exim
Agreement or the Note; (2) the Borrowing Base is less than the sum of
outstanding Advances hereunder; (3) any failure to pay when due any amount
payable to Bank by the Borrower under any loan(s) extended by Bank to Borrower;
(4) the filing of an action for debtor's relief by, against, or on behalf of
Borrower; or (5) any threatened or pending material litigation against Borrower,
or any material dispute involving Borrower.

     In the event that it sends such a notification to Exim Bank, Bank shall
have the right to thereafter send Exim Bank a written report on the status of
the events covered by said notification on each Business Day which occurs every
thirty (30) calendar days after the date of said notification, until such time
as Bank files a claim with Exim Bank or said default or other events have been
cured. Bank shall not have any obligation to make any Advances following said
notification to Exim Bank, unless Exim Bank gives its written approval thereto.
If directed to do so by Exim Bank, Bank shall have a right promptly to exercise
any rights it may have against Borrower to demand the immediate repayment of all
amounts outstanding under the Exim Loan Documents.

     9.4    Remedies Cumulative.  Bank's rights and remedies under this Exim
            -------------------                                             
Agreement, the Exim Loan Documents, the Domestic Loan Documents and all other
agreements shall be cumulative.  Bank shall have all other rights and remedies
not inconsistent herewith as provided under the Code, by law, or in equity.  No
exercise by Bank of one right or remedy shall be deemed an election, and no
waiver by Bank of any Event of Default on Borrower's part shall be deemed a
continuing waiver.  No delay by Bank shall constitute a waiver, election, or
acquiescence by it.

     10.    WAIVERS; INDEMNIFICATION
            ------------------------

     10.1   Demand; Protest.  Except as otherwise set forth herein, Borrower

be liable or responsible for: (a) the safekeeping of the Collateral; (b) any
loss or damage thereto occurring or arising in any manner or fashion

from any cause; (c) any diminution in the value thereof; or (d) any act or
default of any carrier, warehouseman, bailee, forwarding agency, or other person
whomsoever. All risk of loss, damage or destruction of the Collateral shall be
borne by Borrower.

     10.3   Indemnification.  Borrower agrees to defend, indemnify and hold
            ---------------                                                
harmless Bank and its officers, employees, and agents against: (a) all
obligations, demands, claims, and liabilities claimed or asserted by any other
party in connection with the transactions contemplated by this Exim Agreement,

by Bank as a result of or in any way arising out of, following, or consequential
to transactions between Bank and Borrower whether under this Exim Agreement, or
otherwise (including without limitation reasonable attorneys fees and expenses),
except for losses caused by Bank's gross negligence or willful misconduct.

                                  ---------

                           Revolving Promissory Note
                             (Export-Import Line)


$5,000,000.00                                                 September 26, 1997

     FOR VALUE RECEIVED, the undersigned (the "Borrower"), promises to pay to
the order of Silicon Valley Bank ("Bank"), at such place as the holder hereof
may designate, in lawful money of the United States of America, the aggregate
unpaid principal amount of all advances ("Advances") made by Bank to Borrower,
up to a maximum principal amount of Five Million Dollars ($5,000,000), plus
interest on the aggregate unpaid principal amount of such Advances, at the rates
and in accordance with the terms of the Borrower Agreement between Borrower and
Bank of even date herewith, as amended from time to time (the "Loan Agreement")
on the first calendar day of each month after an Advance has been made.  The
entire principal amount and all accrued interest shall be due and payable on
September 25, 1998, or on such earlier date, as provided for in the Loan
Agreement.

     Borrower irrevocably waives the right to direct the application of any and
all payments at any time hereafter received by Bank from or on behalf of
Borrower, and Borrower irrevocably agrees that Bank shall have the continuing
exclusive right to apply any and all such payments against the then due and
owing obligations of Borrower as Bank may deem advisable.  In the absence of a
specific determination by Bank with respect thereto, all payments shall be
applied in the following order: (a) then due and payable fees and expenses; (b)
then due and payable interest payments and mandatory prepayments; and (c) then
due and payable principal payments and optional prepayments.

     Bank is hereby authorized by Borrower to endorse on Bank's books and
records each Advance made by Bank under this Note and the amount of each payment
or prepayment of principal of each such Advance received by Bank; it being
understood, however, that failure to make any such endorsement (or any errors in
notation) shall not affect the obligations of Borrower with respect to Advances
made hereunder, and payments of principal by Borrower shall be credited to
Borrower notwithstanding the failure to make a notation (or any errors in
notation) thereof on such books and records.

     Borrower promises to pay Bank all reasonable costs and reasonable expenses
including all reasonable attorneys' fees, incurred in such collection or in any
suit or action to collect this Note or in any appeal thereof, unless a final
court of competent jurisdiction finds that the Bank acted with gross negligence
or willful misconduct.  Borrower waives presentment, demand, protest, notice of
protest, notice of dishonor, notice of nonpayment, and any and all other notices
and demands in connection with the delivery, acceptance, performance, default or
enforcement of this Note, as well as any applicable statute of limitations.  No
delay by Bank in exercising any power or right hereunder shall operate as a
waiver of any power or right.  Time is of the essence as to all obligations
hereunder.

     This Note is issued pursuant to the Loan Agreement, which shall govern the
rights and obligations of Borrower with respect to all obligations hereunder.

     The law of the Commonwealth of Massachusetts shall apply to this Agreement.
BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES,
UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE COMMONWEALTH OF MASSACHUSETTS IN ANY ACTION, SUIT,
OR PROCEEDING OF ANY KIND, AGAINST IT WHICH ARISES OUT OF OR BY REASON OF THIS
AGREEMENT; PROVIDED, HOWEVER, THAT IF FOR ANY REASON BANK CANNOT AVAIL ITSELF OF
THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS, BORROWER ACCEPTS JURISDICTION
OF THE COURTS AND VENUE IN SANTA CLARA COUNTY, CALIFORNIA.

     BORROWER WAIVES ITS RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY OF THE
TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,
BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW OR STATUTORY CLAIMS.  BORROWER

                                      -14-
<PAGE>
 
RECOGNIZES AND AGREES THAT THE FOREGOING WAIVER CONSTITUTES A MATERIAL
INDUCEMENT FOR IT TO ENTER INTO THIS AGREEMENT. BORROWER REPRESENTS AND WARRANTS
THAT IT HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY
AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL
COUNSEL.
