2. LOAN AND TERMS OF PAYMENT

   For value received, Borrower promises to pay to the order of Bank such
   amount, as provided for below, together with interest, as provided for
   below.

      2.1   Upon the request of Borrower, made at any time and from time to time
   during the term hereof, and so long as no Event of Default has occurred, Bank
   shall lend to Borrower an amount equal to the Borrowing Base; provided,
   however, that in no event shall Bank be obligated to make advances to
   Borrower under this Section 2.1 whenever the Daily Balance exceeds, at any
   time, either the Borrowing Base or the sum of FOUR MILLION AND NO/100
   ($4,000,000.00), such amount being referred to herein as an "Overadvance".
   Borrower shall be allowed to advance up to $2,000,000.00 in excess of the
   eligible borrowing base, provided that such amounts over formula are cash
   secured and are within the commitment amount.

      2.2   Except as hereinbelow provided, the Credit shall bear interest, on
   the Daily Balance owing, at a rate of 500/1000 (0.500) percentage points per
   annum above the Base Rate (the "Rate").  The Credit shall bear interest, from
   and after the occurrence of an Event of Default and without constituting a
   waiver of any such Event of Default, on the Daily Balance owing, at a rate
   three (3) percentage points per annum above the Rate.  All interest
   chargeable under this Agreement that is based upon a per annum calculation
   shall be computed on the basis of a three hundred sixty (360) day year for
   actual days elapsed.

      The Base Rate as of the date of this Agreement is NINE AND NO/1000
   (9.000%) per annum.  In the event that the Base Rate announced is, from time
   to time hereafter changed, adjustment in the Rate shall be made and based on
   the Base Rate in effect on the date of such change.  The Rate, as adjusted,
   shall apply to the Credit until the Base Rate is adjusted again.  The minimum
   interest payable by the Borrower under this Agreement shall in no event be
   less than N/A per month.  All interest payable by Borrower under the Credit
   shall be due and payable on the first day of each calendar month during the
   term of this Agreement and Bank may, at its option, elect to treat such
   interest and any and all Bank Expenses as advances under the Credit, which
   amounts shall thereupon constitute Obligations and shall thereafter accrue
   interest at the rate applicable to the Credit under the terms of the
   Agreement.

      2.3   Without affecting Borrower's obligation to repay immediately any
   Overadvance in accordance with Section 2.1 hereof, all Overadvances shall
   bear additional interest on the amount thereof at a rate equal to N/A (N/A%)
   percentage points per month in excess of the interest rate set forth in
   Section 2.2, from the date incurred and for each month thereafter, until
   repaid in full.

3. TERM

      3.1   This Agreement shall remain in full force and effect until APRIL 30,
   1996, or until terminated by notice by Borrower.  Notice of such termination
   by Borrower shall be effectuated by mailing of a registered or certified
   letter not less than thirty (30) days prior to the effective date of such
   termination, addressed to the Bank at the address set forth herein and the
   termination shall be effective as of the date so fixed in such notice.
   Notwithstanding the foregoing, should Borrower be in default of one or more
   of the provisions of this Agreement, Bank may terminate this Agreement at any
   time without notice.  Notwithstanding the foregoing, should either Bank or
   Borrower become insolvent or unable to meet its debts as they mature, or
   fail, suspend, or go out of business, the other party shall have the right to
   terminate this Agreement at any time without notice.  On the date of
   termination all Obligations shall become immediately due and payable without
   notice or demand; no notice of termination by Borrower shall be effective
   until Borrower shall have paid all Obligations to Bank in full.
   Notwithstanding termination, until all Obligations have been fully satisfied,
   Bank shall retain its security interest in all existing Collateral and
   Collateral arising thereafter, and Borrower shall continue to perform all of
   its Obligations.

      3.2   After termination and when Bank has received payment in full of
   Borrower's Obligations to Bank, Bank shall reassign to Borrower all
   Collateral held by Bank, and shall execute a termination of all security
   agreements and security interests given by Borrower to Bank, upon the
   execution and delivery of mutual general releases.

4. CREATION OF SECURITY INTEREST

   presently existing and hereafter arising Collateral in order to secure prompt

   Obligations under this Agreement and otherwise created.  Bank's security
   interest in the Collateral shall attach to all Collateral without further act
   on the part of Bank or Borrower. In the event that any Collateral,
   including proceeds, is evidenced by or consists of a letter of credit,
   advice of credit, instrument, money, negotiable documents, chattel paper or
   similar property (collectively, "Negotiable Collateral"), Borrower shall,
   immediately upon receipt thereof, endorse and assign such Negotiable
   Collateral over to Bank and deliver actual physical possession of the
   Negotiable Collateral to Bank.


      4.2   Bank's security interest in Receivables shall attach to all

   request from Bank, Borrower shall provide Bank with schedules describing all

   agings listing the names and addresses of, and amounts owing by date by
   account debtors), and shall execute and deliver written assignments of all
   Receivables to Bank all in a form acceptable to Bank, provided, however,
   Borrower's failure to execute and deliver such schedules and/or assignments
   shall not affect or limit Bank's security interest and other rights in and to

   said check or other item of payment shall be deemed to have been paid to Bank
   TWO (2) calendar days after the date Bank actually receives such check or
   other item of payment.

      4.3   Bank's security interest in inventory shall attach to all inventory
   without further act on the part of Bank or Borrower.  Upon Bank's request
   Borrower will from time to time at Borrower's expense pledge, assemble and
   deliver such inventory to Bank or to a third party as Bank's bailee; or hold
   the same in trust for Bank's account or store the same in a warehouse in
   Bank's name; or deliver to Bank documents of title representing said
   inventory; or evidence of Bank's security interest in some other manner
   acceptable to Bank.  Until a default by Borrower under this Agreement or any
   other Agreement between Borrower and Bank, Borrower may, subject to the
   provisions hereof and consistent herewith, sell the inventory, but only in
   the ordinary course of Borrower's business.  A sale of inventory in
   Borrower's ordinary course of business does not include an exchange or a
   transfer in partial or total satisfaction of a debt owing by Borrower.

      4.4   Borrower shall execute and deliver to Bank concurrently with
   Borrower's execution of this Agreement, and at any time or times hereafter at
   the request of Bank, all financing statements, continuation financing
   statements, security agreements, mortgages, assignments, certificates of
   title, affidavits, reports, notices, schedules of accounts, letters of
   authority and all other documents that Bank may request, in form satisfactory
   to Bank, to perfect and maintain perfected Bank's security interest in the
   Collateral and in order to fully consummate all of the transactions
   contemplated under this Agreement.  Borrower hereby irrevocably makes,
   constitutes and appoints Bank (and any of Bank's officers, employees or
   agents designated by Bank) as Borrower's true and lawful attorney-in-fact
   with power to sign the name of Borrower on any financing statements,
   continuation financing statements, security agreement, mortgage, assignment,
   certificate of title, affidavit, letter of authority, notice of other similar
   documents which must be executed and/or filed in order to perfect or continue
   perfected Bank's security interest in the Collateral.

      Borrower shall make appropriate entries in Borrower's Books disclosing
   Bank's security interest in the Receivables.  Bank (through any of its
   officers, employees or agents) shall have the right at any time or times
   hereafter during Borrower's usual business hours, or during the usual
   business hours of any third party having control over the records of
   Borrower, to inspect and verify Borrower's Books in order to verify the
   amount or condition of, or any other matter, relating to, said Collateral and
   Borrower's financial condition.

      4.5   Borrower appoints Bank or any other person whom Bank may designate
   as Borrower's attorney-in-fact, with power to endorse Borrower's name on any
   checks, notes, acceptances, money order, drafts or other forms of payment or
   security that may come into Bank's possession; to sign Borrower's name on any
   invoice or bill of lading relating to any Receivables, on drafts against
   account debtors, on schedules and assignments of Receivables, on
   verifications of Receivables and on notices to account debtors; to establish
   a lock box arrangement and/or to notify the post office authorities to change
   the address for delivery of Borrower's mail addressed to Borrower to an
   address designated by Bank, to receive and open all mail addressed to
   Borrower, and to retain all mail relating to the Collateral and forward all
   other mail to Borrower; to send, whether in writing or by telephone, requests
   for verification of Receivables; and to do all things necessary to carry out
   this Agreement.  Borrower ratifies and approves all acts of the attorney-in-
   fact.  Neither Bank nor its attorney-in-fact will be liable for any acts or
   omissions or for any error of judgement or mistake of fact or law.  This
   power being coupled with an interest, is irrevocable so long as any
   Receivables in which Bank has a security interest remain unpaid and until the
   Obligations have been fully satisfied.

      4.6   In order to protect or perfect any security interest which Bank is
   granted hereunder, Bank may, in its sole discretion, discharge any lien or
   encumbrance or bond the same, pay any insurance, maintain guards,
   warehousemen, or any personnel to protect the Collateral, pay any service
   bureau, or, obtain any records, and all costs for the same shall be added to
   the Obligations and shall be payable on demand.

      4.7   Borrower agrees that Bank may provide information relating to this
   Agreement or relating to Borrower to Bank's parent, affiliates, subsidiaries
   and service providers.

6. WARRANTIES REPRESENTATIONS AND COVENANTS.

   6.1   If so requested by Bank, Borrower shall, at such intervals
designated by Bank, during the term hereof execute and deliver a Report of
Accounts Receivable or similar report, in form customarily used by Bank.
Borrower's Borrowing Base at all times pertinent hereto shall not be less
than the advances made hereunder.  Bank shall have the right to recompute
Borrower's Borrowing Base in conformity with this Agreement.

      6.2   If any warranty is breached as to any account, or any account is not
   paid in full by an account debtor within NINETY (90) days from the date of
   invoice, or an account debtor disputes liability or makes any claim with
   respect thereto, or a petition in bankruptcy or other application for relief
   under the Bankruptcy Code or any other insolvency law is filed by or against
   an account debtor, or an account debtor makes an assignment for the benefit
   of creditors, becomes insolvent, fails or goes out of business, then Bank may
   deem ineligible any and all accounts owing by that account debtor, and reduce
   Borrower's Borrowing Base by the amount thereof.  Bank shall retain its
   security interest in all Receivables and accounts, whether eligible or
   ineligible, until all Obligations have been fully paid and satisfied.
   Returns and allowances, if any, as between Borrower and its customers, will
   be on the same basis and in accordance with the usual customary practices of
   the Borrower, as they exist at this time.  Any merchandise which is returned
   by an account debtor or otherwise recovered shall be set aside, marked with
   Bank's name, and Bank shall retain a security interest therein.  Borrower
   shall promptly notify Bank of all disputes and claims and settle or adjust
   them on terms approved by Bank.  After default by Borrower hereunder, no
   discount, credit or allowance shall be granted to any account debtor by
   Borrower and no return of merchandise shall be accepted by Borrower without
   Bank's consent.  Bank may, after default by Borrower, settle or adjust
   disputes and claims directly with account debtors for amounts and upon terms
   which Bank considers advisable, and in such cases Bank will credit Borrower's
   account with only the net amounts received by Bank in payment of the
   accounts, after deducting all Bank Expenses in connection therewith.

      6.3   Borrower warrants, represents, covenants and agrees that:

         a. Borrower has good and marketable title to the Collateral.  Bank has
         and shall continue to have a first priority perfected security interest
         in and to the Collateral.  The Collateral shall at all times remain
         free and clear of all liens, encumbrances and security interests
         (except those in favor of Bank).

         b. All accounts are and will, at all times pertinent hereto, be bona
         fide existing obligations created by the sale and delivery of
         merchandise or the rendition of services to account debtors in the
         ordinary course of business, free of liens, claims, encumbrances and
         security interests (except as held by Bank and except as may be
         consented to, in writing, by Bank) and are unconditionally owed to
         Borrower without defenses, disputes, offsets, counterclaims, rights of
         return or cancellation, and Borrower shall have received no notice of
         actual or imminent bankruptcy or insolvency of any account debtor at
         the time an account due from such account debtor is assigned to Bank.

         c. At the time each account is assigned to Bank, all property giving
         rise to such account shall have been delivered to the account debtor or
         to the agent for the account debtor for immediate shipment to, and
         unconditional acceptance by, the account debtor.  Borrower shall
         deliver to Bank, as Bank may from time to time require, delivery
         receipts, customer's purchase orders, shipping instruction, bills of
         lading and any other evidence of shipping arrangements.  Absent such a
         request by Bank, copies of all such documentation shall be held by
         Borrower as custodian for Bank.

      6.4   At the time each eligible account is assigned to Bank, all such
   eligible accounts will be due and payable on terms set forth in Section 1.12,
   or on such other terms approved in writing by Bank in advance of the creation
   of such accounts and which are expressly set forth on the face of all
   invoices, copies of which shall be held by Borrower as custodian for Bank,
   and no such eligible account will then be past due.

   (i) make payment of the same or any part thereof; or (ii) set up such
   reserves in Borrower's account as Bank deems necessary to satisfy the
   liability therefor, or both.  Bank may conclusively rely on the usual
   statements of the amount owing or other official statements issued by the
   appropriate governmental agency.  Each amount so paid or deposited by Bank
   shall constitute a Bank Expense and an additional advance to Borrower.

      6.13  There are no actions or proceedings pending by or against Borrower
   or any guarantor of Borrower before any court or administrative agency and
   Borrower has no knowledge of any pending, threatened or imminent litigation,
   governmental investigations or claims, complaints, actions or prosecutions
   involving Borrower or any guarantor of Borrower, except as heretofore
   specifically disclosed in writing to Bank.  If any of the foregoing arise
   during the term of the Agreement, Borrower shall immediately notify Bank in
   writing.

      6.14 a. Borrower, at its expense, shall keep and maintain its assets
   insured against loss or damage by fire, theft, explosion, sprinklers and all
   other hazards and risks ordinarily insured against by other owners who use
   such properties in similar businesses for the full insurable value thereof.
   Borrower shall also keep and maintain business interruption insurance and
   public liability and property damage insurance relating to Borrower's
   ownership and use of the Collateral and its other assets.  All such policies
   of insurance shall be in such form, with such companies, and in such amounts
   as may be satisfactory to Bank.  Borrower shall deliver to Bank certified
   copies of such policies of insurance and evidence of the payments of all
   premiums therefor.  All such policies of insurance (except those of public
   liability and property damage) shall contain an endorsement in a form
   satisfactory to Bank showing Bank as a loss payee thereof, with a waiver of
   warranties (Form 438-BFU), and all proceeds payable thereunder shall be
   payable to Bank and, upon receipt by Bank, shall be applied on account of the
   Obligations owing to Bank.  To secure the payment of the Obligations,
   Borrower grants Bank a security interest in and to all such policies of
   insurance (except those of public liability and property damage) and the
   proceeds thereof, and Borrower shall direct all insurers under such policies
   of insurance to pay all proceeds thereof directly to Bank.

   b. Borrower hereby irrevocable appoints Bank (and any of Bank's officers,
   employees or agents designated by Bank) as Borrower's attorney for the
   purpose of making, selling and adjusting claims under such policies of
   insurance, endorsing the name of Borrower on any check, draft, instrument or
   other item of payment for the proceeds of such policies of insurance and for
   making all determinations and decisions with respect to such policies of
   insurance.  Borrower will not cancel any of such policies without Bank's
   prior written consent.  Each such insurer shall agree by endorsement upon the
   policy or policies of insurance issued by it to Borrower as required above,
   or by independent instruments furnished to Bank, that it will give Bank at
   least ten (10) days written notice before any such policy or policies of
   insurance shall be altered or cancelled, and that no act or default of
   Borrower, or any other person, shall affect the right of Bank to recover
   under such policy or policies of insurance required above or to pay any
   premium in whole or in part relating thereto.  Bank, without waiving or
   releasing any Obligations or any Event of Default, may, but shall have no
   obligation to do so, obtain and maintain such policies of insurance and pay
   such premiums and take any other action with respect to such policies which
   Bank deems advisable.  All sums so disbursed by Bank, as well as reasonable
   attorneys' fees, court costs, expenses and other charges relating thereto,
   shall constitute Bank Expenses and are payable on demand.

      6.15  All financial statements and information relating to Borrower which
   have been or may hereafter be delivered by Borrower to Bank are true and
   correct and have been prepared in accordance with GAAP consistently applied
   and there has been no material adverse change in the financial condition of
   Borrower since the submission of such financial information to Bank.

      6.16  a. Borrower at all times hereafter shall maintain a standard and
   modern system of accounting in accordance with GAAP consistently applied with
   ledger and account cards and/or computer tapes and computer disks, computer
   printouts and computer records pertaining to the Collateral which contain
   information as may from time to time be requested by Bank, not modify or
   change its method of accounting or enter into, modify or terminate any
   agreement presently existing, or at any time hereafter entered into with any
   third party accounting firm and/or service bureau for the preparation and/or

         on or after which the private sale or other disposition is to be made;

         (2) The notice shall be personally delivered or mailed, postage
         prepaid, to Borrower's address appearing in this Agreement, at
         least five (5) calendar days before the date fixed for the sale, or

         the private sale or other disposition is to be made, unless the

         value. Notice to persons other than Borrower claiming an interest

     maintains with Bank against the Obligations.


      8.2 Bank's rights and remedies under this Agreement and all other
   agreements shall be cumulative. Bank shall have all other rights and
   remedies not inconsistent herewith as provided 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 default on Borrower's part shall be deemed a
   continuing waiver. No delay by Bank shall constitute a waiver, election or
   acquiescence by Bank.

monies which Borrower is required to pay by reason of any provision in
this Agreement, Bank may, but need not, pay the same and charge Borrower's
account therefor, and Borrower shall promptly reimburse Bank.  All such sums
shall become additional indebtedness owing to Bank, shall bear interest at the
rate hereinabove provided, and shall be secured by all Collateral. Any
payments made by Bank shall not constitute (i) an agreement by it to make
similar payments in the future; or (ii) a waiver by Bank of any default under
this Agreement. Bank need not inquire as to, or contest the validity of, any
such expense, tax, security interest, encumbrance or lien and the receipt of
the usual official notice of the payment thereof shall be conclusive evidence
that the same was validly due and owing. Such payments shall constitute Bank
Expenses and additional advances to Borrower.

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

   act or default of any carrier, warehouseman, bailee, forwarding agency
   or other person whomsoever. All risk of loss, damage or destruction
   of inventory shall be borne by Borrower.

   10.6  In the event that Bank elects to waive any rights or remedies
   hereunder, or compliance with any of the terms hereof, or delays or fails
   to pursue or enforce any terms, such waiver, delay or failure to pursue
   or enforce shall only be effective with respect to that single act and
   shall not be construed to affect any subsequent transactions or Bank's
   right to later pursue such rights and remedies.

Bank to Borrower under this Agreement or any other agreement between Bank and
Borrower, shall constitute one loan secured by Bank's security interests in the

party, and Borrower shall hold Bank harmless from any damage, claims or
liability by reason of Bank's honor of, or failure to honor, any such
instructions.

14.   DESTRUCTION OF BORROWER'S DOCUMENTS.

Any documents, schedules, invoices or other papers delivered to Bank, may be
destroyed or otherwise disposed of by Bank six (6) months after they are

return of the said documents, schedules, invoices or other papers and makes
arrangements, at Borrower's expense, for their return.

15.   CHOICE OF LAW.

The validity of this Agreement, its construction, interpretation and
enforcement, and the rights of the parties hereunder and concerning the

connection with this Agreement shall be tried and litigated only in the state
and federal courts in the Northern District of California or County of Santa
Clara.

      16.1  This Agreement shall be binding and deemed effective when executed
   by the Borrower and accepted and executed by Bank at its Headquarter Office.

   prior written consent and any prohibited assignment shall be absolutely void.
   No consent to an assignment by Bank shall release Borrower or any guarantor
   from their Obligations to Bank.  Bank may assign this Agreement and its
   rights and duties hereunder.  Bank reserves the right to sell, assign,
   transfer, negotiate or grant participations in all or any part of, or any

   Agreement.

   be construed or resolved against Bank or Borrower, whether under any rule of
   construction or otherwise; on the contrary, this Agreement has been reviewed
   by all parties and shall be construed and interpreted according to the
   ordinary meaning of the words used so as to fairly accomplish the purposes
   and intentions of all parties hereto.  When permitted by the context, the
