                                    RECITALS

     A.   Bank agreed to make revolving loans to Borrower in the maximum
principal amount of $8,000,000.00 ("Commitment") pursuant to the terms of that

Commitment.

     B.   The Commitment terminated and the Note matured on December 29, 1997,
and Borrower desires to extend the termination date of the Commitment and the

conditions set forth herein.

     C.   The Credit Terms Agreement, the Note (as amended hereby), this First
Amendment, together with all other documents entered into or delivered pursuant
to any of the foregoing, in each case as originally executed or as the same may
from time to time be modified, amended, supplemented, restated or superseded
are hereinafter collectively referred to as the "Loan Documents."

                                   AGREEMENT

     NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
covenants herein set forth and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, and intending to be
legally bound, Borrower and Bank hereby agree to amend the Loan Documents as
follows:

     1.   DEFINITIONS. Unless otherwise defined herein, all terms used in the
Credit Terms Agreement have the same meaning when used herein.

     2.   AMENDMENTS TO CREDIT TERMS AGREEMENT. The terms of the Credit Terms
Agreement are hereby amended as follows:

          a.   A portion of the first sentence of SECTION B.4.(c) of the Credit
Terms and Conditions containing the words "Within 45 days after the end of each
fiscal quarter of Borrower, a certificate of chief of financial officer or
partner of Borrower," is hereby deleted in its entirety and replaced with the
following partial sentence:


                                       1.
   2
               "(c) As a condition to any request for a Loan under the
          Commitment, Borrower shall have delivered to Bank a compliance
          certificate, certified by an officer of Borrower, covering the most
          recent fiscal quarter then ended prior to the date of Borrower's
          request for a Loan,"

          b.   PARAGRAPH 1) under the Reporting requirement in the Addendum is
hereby deleted in its entirety and replaced with the following paragraph:

          "1)  Quarterly 10-Q reports within 45 days of quarter end."

          c.   The Addendum is hereby amended to add the following additional
sections thereunder:

          "COMMITMENT"

          Subject to all the terms and conditions of this Credit Terms and
          Conditions and Addendum as attached thereto, and prior to the
          termination of its commitment as hereinafter provided, Bank hereby
          agrees to make loans (each a "Loan" and collectively, "Loans") to
          Borrower, in such amounts as Borrower shall request, at any time from
          December 29, 1997 through December 28, 1998 (the "Commitment
          Termination Date"), in an aggregate principal amount not to exceed
          $8,000,000.00 (the "Commitment"). If at any time or for any reason,
          the outstanding principal amount advanced under the Commitment is
          greater than $8,000,000.00, Borrower shall immediately pay to Bank, in
          cash, the amount of such excess. Any commitment of Bank, pursuant to
          the terms hereof to make Loans shall expire on the Commitment
          Termination Date, subject to Bank's right to renew said commitment in
          its sole and absolute discretion at Borrower's request. Any such
          renewal of said commitment shall not be binding upon Bank unless it is
          in writing and signed by an officer of Bank. Provided that no event of
          default has occurred and is continuing hereunder, all or any portion
          of the Loans advanced by Bank under the Commitment which are repaid by
          Borrower shall be available for reborrowing in accordance with the
          terms hereof. Borrower promises to pay to Bank the entire outstanding
          principle balance (and all accrued unpaid interest thereon) of the
          Commitment on the Commitment Termination Date.

          1)   Letter of Credit Usage and Sublimit. Subject to the availability
               of the Commitment and in reliance on the representations and
               warranties of Borrower set forth herein, at any time and from
               time to time from the date hereof through the banking day
               immediately prior to the Commitment Termination Date, Bank shall
               issue for the account of Borrower such standby and commercial
               letters of credit ("Letters of Credit") as Borrower may request,
               which request shall be made by delivering to Bank a duly executed
               letter of credit application on Bank's standard form; provided,
               however, that the outstanding and undrawn amounts under all such
               Letters


                                       2.
   3
          of Credit (a) shall not at any time exceed $1,000,000.00 and (b) shall
          be deemed to constitute Loans for the purpose of calculating
          availability under the Commitment. Unless Borrower shall have
          deposited with Bank cash collateral in an amount sufficient to cover
          all undrawn amounts under each such Letter of Credit and Bank shall
          have agreed in writing, no Letter of Credit shall have an expiration
          date that is later than the Commitment Termination Date. All Letters
          of Credit shall be in form and substance acceptable to Bank in its
          sole discretion and shall be subject to the terms and conditions of
          Bank's form application and letter of credit agreement. Borrower will
          pay any standard issuance and other fees that Bank notifies Borrower
          will be charged for issuing and processing Letters of Credit for
          Borrower.

     2)   Foreign Exchange Usage and Sublimit.  Subject to the availability of
          the Commitment and in reliance on the representations and warranties
          of Borrower set forth herein, at any time and from time to time from
          the date hereof through the banking day immediately prior to the
          Commitment Termination Date, Bank shall arrange the purchase by
          Borrower of foreign exchange futures contracts ("Exchange Contracts")
          as Borrower may request, which request shall be made by delivering to
          Bank a duly executed exchange contract application on Bank's standard
          form; provided, however, that the maximum aggregate notional contract
          amount under all such Exchange Contracts shall not at any time exceed
          $1,000,000.00; provided, further, that 10% of the maximum aggregate
          notional contract amount under all such Exchange Contracts shall be
          deemed to constitute outstanding Loans for the purpose of calculating
          availability under the Commitment. Unless Borrower shall have
          deposited with Bank cash collateral in an amount sufficient to cover
          all undrawn amounts under each such Exchange Contract and Bank shall
          have agreed in writing, no Exchange Contract shall have a due date
          that is later than the Commitment Termination Date. All Exchange
          Contracts shall be in form and substance acceptable to Bank in its
          sole discretion and shall be subject to the terms and conditions of
          Bank's form exchange contract application. Borrower will pay any
          standard issuance and other fees that Bank notifies Borrower will be
          charged for issuing and processing Exchange Contracts for Borrower.
          After and during the continuance of an Event of Default, Bank may, in
          its sole and absolute discretion, terminate any or all of the Exchange
          Contracts. Borrower agrees to indemnify and hold harmless Bank from
          and against all loss, costs and expense associated with any such
          termination of any Exchange Contract."

     3.   AMENDMENT TO NOTE. The stated maturity date of the Note is hereby
extended from December 29, 1997 to December 28, 1998.



                                       3.
   4
     4.   REPRESENTATIONS AND WARRANTIES. Borrower represents and warrants that
its representations and warranties in the Loan Documents continue to be true
and complete in all material respects as of the date hereof after giving effect
to this First Amendment (except to the extent such specifically relate to
another date or as specifically described on EXHIBIT A attached hereto and
incorporated herein by his reference) and that the execution, delivery and
performance of this First Amendment are duly authorized, do not require the
consent or approval of any governmental body or regulatory authority and are
not in contravention of or in conflict with any law or regulation or any term
or provision of any other agreement entered into by Borrower.

     5.   CONDITIONS PRECEDENT. The legal effectiveness of this First Amendment
is subject to the satisfaction of all of the following conditions precedent:

          a.   PAYMENT OF ACCRUED INTEREST. Bank shall have received all unpaid
interest accrued under the Note from December 1, 1997 through and including
December 29, 1997 at the rate of interest and computed in accordance with the
terms of the Note.

          b.   EXECUTED AMENDMENT. Bank shall have received this First
Amendment duly executed and delivered by Borrower.

          c.   RESOLUTIONS AND OTHER CORPORATE DOCUMENTS OF BORROWER. Bank
shall have received resolutions of the Board of Directors of Borrower
authorizing Borrower to enter into this First Amendment and such other
corporate documents as Bank shall reasonably request.

          d.   FINANCIAL CONDITION. There shall have occurred no material
adverse change in the financial condition or prospects of Borrower as shown on
the most recent financial statements submitted to Bank or disclosed to Bank,
respectively, and relied upon by Bank in entering into this First Amendment.

          e.   NO DEFAULT. There shall have occurred no Event of Default that
remains uncured and is continuing under any of the Loan Documents.

          f.   PAYMENTS OF FEES. Bank shall have received reimbursement from
Borrower of its costs and expenses incurred (including, without limitation, its
attorneys' fees and expenses) in connection with this First Amendment and the
transactions contemplated hereby.

          g.   OTHER DOCUMENTS. Bank shall have received such other documents,
information and items from Borrower as it shall reasonably request to effectuate
the transactions contemplated hereby.

     6.   RELEASE AND WAIVER.

          a.   Borrower hereby acknowledges and agree that: (1) it has no claim
or cause of action against Bank or any parent, subsidiary or affiliate of Bank,
or any of Bank's officers, directors, employees, attorneys or other
representatives or agents (all of which parties 


                                       4.
   5
other than Bank being, collectively, "Bank's Agents") in connection with the
Loan Documents, the loans thereunder or the transactions contemplated therein
and herein; (2) it has no offset or defense against any of its respective
obligations, indebtedness or contracts in favor of Bank; and (3) it recognizes
that Bank has heretofore properly performed and satisfied in a timely manner
all of its obligations to and contracts with Borrower.

     b.   Although Bank regards its conduct as proper and does not believe
Borrower to have any claim, cause of action, offset or defense against Bank or
any of Bank's Agents in connection with the Loan Documents, the loans
thereunder or the transactions contemplated therein, Bank wishes and Borrower
agrees to eliminate any possibility that any past conditions, acts, omissions,
events, circumstances or matters could impair or otherwise affect any rights,
interests, contracts or remedies of Bank. Therefore, Borrower unconditionally
releases and waives (1) any and all liabilities, indebtedness and obligations,
whether known or unknown, of any kind to Bank or of any of Bank's Agents to
Borrower, except the obligations remaining to be performed by Bank as expressly
stated in the Credit Terms Agreement, this First Amendment and the other Loan
Documents executed by Bank; (2) any legal, equitable or other obligations or
duties, whether known or unknown, of Bank or of any of Bank's Agents to
Borrower (and any rights of Borrower against Bank) besides those expressly
stated in the Credit Terms Agreement, this First Amendment and the other Loan
Documents; (3) any and all claims under any oral or implied agreement,
obligation or understanding with Bank or any of Bank's Agents, whether known or
unknown, which is different from or in addition to the express terms of the
Credit Terms Agreement, this First Amendment or any of the other Loan
Documents; and (4) all other claims, causes of action or defenses of any kind
whatsoever (if any), whether known or unknown, which Borrower might otherwise
have against Bank or any of Bank's Agents, on account of any condition, act,
omission, event, contract, liability, obligation, indebtedness, claim, cause of
action, defense, circumstance or matter of any kind whatsoever which existed,
arose or occurred at any time prior to the execution and delivery of this First
Amendment or which could arise concurrently with the effectiveness of this
First Amendment.

     c.   Borrower agrees that it understands the meaning and effect of Section
1542 of the California Civil Code, which provides:

          Section 1542. Certain Claims Not Affected by General Release. A
          general releases does not extend to claims which the creditor does not
          know or suspect to exist in his favor at the time of executing the
          release, which if known by him must have materially affected his
          settlement with the debtor.

BORROWER AGREES TO ASSUME THE RISK OF ANY AND ALL UNKNOWN, UNANTICIPATED OR
MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF ACTION, CONTRACTS, LIABILITIES,
INDEBTEDNESS AND OBLIGATIONS WHICH ARE RELEASED BY THIS FIRST AMENDMENT IN
FAVOR OF BANK AND BANK'S AGENTS, AND BORROWER HEREBY WAIVES AND RELEASES ALL
RIGHTS AND BENEFITS WHICH IT MIGHT OTHERWISE HAVE UNDER THE AFOREMENTIONED
SECTION 1542 OF THE CALIFORNIA CIVIL CODE WITH REGARD TO THE RELEASE

                                       5.
   6
OF SUCH UNKNOWN, UNANTICIPATED OR MISUNDERSTOOD DEFENSES, CLAIMS, CAUSES OF
ACTION, CONTRACTS, LIABILITIES, INDEBTEDNESS AND  OBLIGATIONS. TO THE EXTENT
(IF ANY) WHICH ANY SUCH LAWS MAY BE APPLICABLE, BORROWER WAIVES AND RELEASES
(TO THE MAXIMUM EXTENT PERMITTED BY LAW) ANY RIGHT OR DEFENSE WHICH IT MIGHT
OTHERWISE HAVE UNDER ANY OTHER LAW OF ANY APPLICABLE JURISDICTION WHICH MIGHT
LIMIT OR RESTRICT THE EFFECTIVENESS OR SCOPE OF ANY OF ITS WAIVERS OR RELEASES
UNDER THIS FIRST AMENDMENT.

     7.     FULL, FORCE AND EFFECT; ENTIRE AGREEMENT. Except to the extent
expressly provided in this First Amendment, the terms and conditions of the
Credit Terms Agreement and the other Loan Documents shall remain in full force
and effect. This First Amendment and the other Loan Documents constitute and
contain the entire agreement of the parties hereto and supersede any and all
prior agreements, negotiations, correspondence, understandings and
communications between the parties, whether written or oral, respecting the
subject matter hereof. The parties hereto further agree that the Loan Documents
comprise the entire agreement of the parties thereto and supersede any and all
prior agreements, negotiations, correspondence, understandings and other
communications between the parties thereto, whether written or oral respecting
the extension of credit by Bank to Borrower and/or its affiliates.

     8.     COUNTERPARTS; EFFECTIVENESS. This First Amendment may be executed in
any number of counterparts, each of which when so delivered shall be deemed an
original, but all such counterparts taken together shall constitute but one
and the same instrument. Each such agreement shall become effective upon the
execution of a counterpart hereof or thereof by each of the parties hereto and
telephonic notification that such executed counterparts has been received by
Borrower and Bank.

     IN WITNESS WHEREOF, each of the parties hereto has caused this First
Amendment to be executed and delivered by its duly authorized officer as of the
date first written above.
