                               SILICON VALLEY BANK

                           LOAN AND SECURITY AGREEMENT

BORROWER:         AG ASSOCIATES
ADDRESS:          4425 FORTRAN DRIVE
                  SAN JOSE, CA  95134

DATE:             JUNE 23, 1998


THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address"). The Schedule to this Agreement (the
"Schedule") shall for all purposes be deemed to be a part of this Agreement, and
the same is an integral part of this Agreement. (Definitions of certain terms
used in this Agreement are set forth in Section 8 below.)

1.   LOANS.

   1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), in amounts
determined by Silicon in its sole discretion, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing, and subject to deduction of any Reserves for accrued
interest and such other Reserves as Silicon deems proper from time to time.

   1.2 INTEREST. All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

   1.3 OVERADVANCES. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

   1.4 FEES. Borrower shall pay Silicon the fee(s) shown on the Schedule, which
are in addition to all interest and other sums payable to Silicon and are not
refundable.

   1.5 LETTERS OF CREDIT. At the request of Borrower, Silicon may, in its sole
discretion, issue or arrange for the issuance of letters of credit for the
account of Borrower, in each case in form and substance satisfactory to Silicon
in its sole discretion (collectively, "Letters of Credit"). The aggregate face
amount of all outstanding Letters of Credit from time to time shall not exceed
the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder. Borrower
shall pay all bank charges (including charges of Silicon) for the issuance of
Letters of Credit, together with such additional fee as Silicon's letter of
credit department shall charge in connection with the issuance of the Letters of
Credit. Any payment by Silicon under or in connection with a Letter of Credit
shall constitute a Loan hereunder on the date such payment is made. Each Letter
of Credit shall have an expiry date no later than thirty days prior to the
Maturity Date. Borrower hereby agrees to indemnify, save, and hold Silicon
harmless from any loss, cost, expense, or liability, including payments made by
Silicon, expenses, and reasonable attorneys' fees incurred by Silicon arising
out of or in connection with any Letters of Credit. Borrower agrees to be bound
by the regulations and interpretations of the issuer of any Letters of Credit
guarantied by Silicon and opened for Borrower's account or by Silicon's
interpretations of any Letter of Credit issued by Silicon for Borrower's
account, and Borrower understands and agrees that Silicon shall not be liable
for any error, negligence, or mistake, whether of omission or commission, in
following Borrower's instructions or those contained in the Letters of Credit or
any modifications, amendments, or supplements thereto. Borrower understands that
Letters of Credit may require Silicon to indemnify the issuing bank for certain
costs or liabilities arising out of claims by Borrower against such issuing
bank. Borrower hereby agrees to indemnify and hold Silicon harmless with respect
to any loss, cost, expense, or liability incurred by Silicon under any Letter of
Credit as a result of Silicon's indemnification of any such issuing bank. The
provisions of this Loan Agreement, as it pertains to Letters of Credit, and any
other present or

--------------------------------------------------------------------------------

future documents or agreements between Borrower and Silicon relating to Letters
of Credit are cumulative.

2.  SECURITY INTEREST.

   2.1 SECURITY INTEREST. To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to Silicon a security interest in
all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located (collectively, the "Collateral"): All Inventory,
Equipment, Receivables, and General Intangibles, including, without limitation,
all of Borrower's Deposit Accounts, and all money, and all property now or at
any time in the future in Silicon's possession (including claims and credit
balances), and all proceeds (including proceeds of any insurance policies,
proceeds of proceeds and claims against third parties), all products and all
books and records related to any of the foregoing (all of the foregoing,
together with all other property in which Silicon may now or in the future be
granted a lien or security interest, is referred to herein, collectively, as the
"Collateral").

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

   In order to induce Silicon to enter into this Agreement and to make Loans,
Borrower represents and warrants to Silicon as follows, and Borrower covenants
that the following representations will continue to be true, and that Borrower
will at all times comply with all of the following covenants:

   3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

   3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

   3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth in the
heading to this Agreement is Borrower's chief executive office. In addition,
Borrower has places of business and Collateral is located only at the locations
set forth on the Schedule. Borrower will give Silicon at least 30 days prior
written notice before opening any additional place of business, changing its
chief executive office, or moving any of the Collateral to a location other than
Borrower's Address or one of the locations set forth on the Schedule.

   3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower. The Collateral now is and will remain
free and clear of any and all liens, charges, security interests, encumbrances
and adverse claims, except for Permitted Liens. Silicon now has, and will
continue to have, a first-priority perfected and enforceable security interest
in all of the Collateral, subject only to the Permitted Liens, and Borrower will
at all times defend Silicon and the Collateral against all claims of others.
None of the Collateral now is or will be affixed to any real property in such a
manner, or with such intent, as to become a fixture. Borrower is not and will
not become a lessee under any real property lease pursuant to which the lessor
may obtain any rights in any of the Collateral and no such lease now prohibits,
restrains, impairs or will prohibit, restrain or impair Borrower's right to
remove any Collateral from the leased premises. Whenever any Collateral is
located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Silicon, use its best efforts to cause
such third party to execute and deliver to Silicon, in form acceptable to
Silicon, such waivers and subordinations as Silicon shall specify, so as to
ensure that Silicon's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. Borrower will keep in full force
and effect, and will comply with all the terms of, any lease of real property
where any of the Collateral now or in the future may be located.

   3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in good
working condition, and Borrower will not use the Collateral for any unlawful
purpose. Borrower will immediately advise Silicon in writing of any material
loss or damage to the Collateral.

   3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

   3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial statements now
or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date hereof, there has
been no material adverse change in the financial condition or business of
Borrower. Borrower is now and will continue to be solvent.

   3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has timely
filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local



                                      -3-

SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------



taxes, assessments, deposits and contributions now or in the future owed by
Borrower. Borrower may, however, defer payment of any contested taxes, provided
that Borrower (i) in good faith contests Borrower's obligation to pay the taxes
by appropriate proceedings promptly and diligently instituted and conducted,
(ii) notifies Silicon in writing of the commencement of, and any material
development in, the proceedings, and (iii) posts bonds or takes any other steps
required to keep the contested taxes from becoming a lien upon any of the
Collateral. Borrower is unaware of any claims or adjustments proposed for any of
Borrower's prior tax years which could result in additional taxes becoming due
and payable by Borrower. Borrower has paid, and shall continue to pay all
amounts necessary to fund all present and future pension, profit sharing and
deferred compensation plans in accordance with their terms, and Borrower has not
and will not withdraw from participation in, permit partial or complete
termination of, or permit the occurrence of any other event with respect to, any
such plan which could result in any liability of Borrower, including any
liability to the Pension Benefit Guaranty Corporation or its successors or any
other governmental agency. Borrower shall, at all times, utilize the services of
an outside payroll service providing for the automatic deposit of all payroll
taxes payable by Borrower.

   3.9 COMPLIANCE WITH LAW. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

   3.10 LITIGATION. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of
$50,000 or more, or involving $100,000 or more in the aggregate.

   3.11 USE OF PROCEEDS. All proceeds of all Loans shall be used solely for
lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

4.  RECEIVABLES.

   4.1 REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and warrants
to Silicon as follows: Each Receivable with respect to which Loans are requested
by Borrower shall, on the date each Loan is requested and made, (i) represent an
undisputed bona fide existing unconditional obligation of the Account Debtor
created by the sale, delivery, and acceptance of goods or the rendition of
services in the ordinary course of Borrower's business, and (ii) meet the
Minimum Eligibility Requirements set forth in Section 8 below.

   4.2 REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. Borrower
represents and warrants to Silicon as follows: All statements made and all
unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract. All sales and
other transactions underlying or giving rise to each Receivable shall fully
comply with all applicable laws and governmental rules and regulations. All
signatures and endorsements on all documents, instruments, and agreements
relating to all Receivables are and shall be genuine, and all such documents,
instruments and agreements are and shall be legally enforceable in accordance
with their terms.

   4.3 SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES. Borrower shall deliver
to Silicon transaction reports and loan requests, schedules and assignments of
all Receivables, and schedules of collections, all on Silicon's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Silicon's security interest and other rights in all of
Borrower's Receivables, nor shall Silicon's failure to advance or lend against a
specific Receivable affect or limit Silicon's security interest and other rights
therein. Loan requests received after 12:00 Noon will not be considered by
Silicon until the next Business Day. Together with each such schedule and
assignment, or later if requested by Silicon, Borrower shall furnish Silicon
with copies (or, at Silicon's request, originals) of all contracts, orders,
invoices, and other similar documents, and all original shipping instructions,
delivery receipts, bills of lading, and other evidence of delivery, for any
goods the sale or disposition of which gave rise to such Receivables, and
Borrower warrants the genuineness of all of the foregoing. Borrower shall also
furnish to Silicon an aged accounts receivable trial balance in such form and at
such intervals as Silicon shall request. In addition, Borrower shall deliver to
Silicon the originals of all instruments, chattel paper, security agreements,
guarantees and other documents and property evidencing or securing any
Receivables, immediately upon receipt thereof and in the same form as received,
with all necessary indorsements, all of which shall be with recourse. Borrower
shall also provide Silicon with copies of all credit memos within two days after
the date issued.

   4.4 COLLECTION OF RECEIVABLES. Borrower shall have the right to collect all
Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Silicon, and Borrower shall immediately deliver all such payments and proceeds
to Silicon in their original form, duly endorsed in blank, to be applied to the
Obligations in such order as Silicon shall determine. Silicon may, in its
discretion, require that all proceeds of Collateral be deposited by Borrower
into a lockbox account, or such other "blocked account" as Silicon may specify,
pursuant to a blocked account agreement in such form as Silicon may specify.
Silicon or its designee may, at any time, notify Account Debtors that the
Receivables have been assigned to Silicon.

SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------



   4.5. REMITTANCE OF PROCEEDS. All proceeds arising from the disposition of any
Collateral shall be delivered, in kind, by Borrower to Silicon in the original
form in which received by Borrower not later than the following Business Day
after receipt by Borrower, to be applied to the Obligations in such order as
Silicon shall determine; provided that, if no Default or Event of Default has
occurred, Borrower shall not be obligated to remit to Silicon the proceeds of
the sale of worn out or obsolete equipment disposed of by Borrower in good faith
in an arm's length transaction for an aggregate purchase price of $25,000 or
less (for all such transactions in any fiscal year). Borrower agrees that it
will not commingle proceeds of Collateral with any of Borrower's other funds or
property, but will hold such proceeds separate and apart from such other funds
and property and in an express trust for Silicon. Nothing in this Section limits
the restrictions on disposition of Collateral set forth elsewhere in this
Agreement.

   4.6 DISPUTES. Borrower shall notify Silicon promptly of all disputes or
claims relating to Receivables. Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Silicon on the regular reports provided to Silicon; (ii) no Default
or Event of Default has occurred and is continuing; and (iii) taking into
account all such discounts settlements and forgiveness, the total outstanding
Loans will not exceed the Credit Limit. Silicon may, at any time after the
occurrence of an Event of Default, settle or adjust disputes or claims directly
with Account Debtors for amounts and upon terms which Silicon considers
advisable in its reasonable credit judgment and, in all cases, Silicon shall
credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

   4.7 RETURNS. Provided no Event of Default has occurred and is continuing, if
any Account Debtor returns any Inventory to Borrower in the ordinary course of
its business, Borrower shall promptly determine the reason for such return and
promptly issue a credit memorandum to the Account Debtor in the appropriate
amount (sending a copy to Silicon). In the event any attempted return occurs
after the occurrence of any Event of Default, Borrower shall (i) hold the
returned Inventory in trust for Silicon, (ii) segregate all returned Inventory
from all of Borrower's other property, (iii) conspicuously label the returned
Inventory as Silicon's property, and (iv) immediately notify Silicon of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

   4.8 VERIFICATION. Silicon may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or Silicon or such other name as Silicon may choose.

   4.9 NO LIABILITY. Silicon shall not under any circumstances be responsible or
liable for any shortage or discrepancy in, damage to, or loss or destruction of,
any goods, the sale or other disposition of which gives rise to a Receivable, or
for any error, act, omission, or delay of any kind occurring in the settlement,
failure to settle, collection or failure to collect any Receivable, or for
settling any Receivable in good faith for less than the full amount thereof, nor
shall Silicon be deemed to be responsible for any of Borrower's obligations
under any contract or agreement giving rise to a Receivable. Nothing herein
shall, however, relieve Silicon from liability for its own gross negligence or
willful misconduct.

5.  ADDITIONAL DUTIES OF THE BORROWER.

   5.1 FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply with
the financial and other covenants set forth in the Schedule.

   5.2 INSURANCE. Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies shall name Silicon as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Silicon. Upon receipt of the proceeds of any such
insurance, Silicon shall apply such proceeds in reduction of the Obligations as
Silicon shall determine in its sole discretion, except that, provided no Default
or Event of Default has occurred and is continuing, Silicon shall release to
Borrower insurance proceeds with respect to Equipment totaling less than
$100,000, which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid. Silicon may
require reasonable assurance that the insurance proceeds so released will be so
used. If Borrower fails to provide or pay for any insurance, Silicon may, but is
not obligated to, obtain the same at Borrower's expense. Borrower shall promptly
deliver to Silicon copies of all reports made to insurance companies.

   5.3 REPORTS. Borrower, at its expense, shall provide Silicon with the written
reports set forth in the Schedule, and such other written reports with respect
to Borrower (including budgets, sales projections, operating plans and other
financial documentation), as Silicon shall from time to time reasonably specify.

   5.4 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times, and on one
Business Day's notice, Silicon, or its agents, shall have the right to inspect
the Collateral, and the right to audit and copy Borrower's books and records.
Silicon shall take reasonable steps to keep confidential all information
obtained in any such inspection or audit, but Silicon shall have the right to
disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The foregoing
inspections and audits shall be at Borrower's expense and the charge therefor
shall be $500 per person per day (or such higher amount as shall represent
Silicon's then current standard charge for the same), plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, 



                                      -5-
<PAGE>   6
SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------



without first obtaining Silicon's written consent, which may be conditioned upon
such accounting firm, service bureau or other third party agreeing to give
Silicon the same rights with respect to access to books and records and related
rights as Silicon has under this Loan Agreement. Borrower waives the benefit of
any accountant-client privilege or other evidentiary privilege precluding or
limiting the disclosure, divulgence or delivery of any of its books and records
(except that Borrower does not waive any attorney-client privilege).

   5.5 NEGATIVE COVENANTS. Except as may be permitted in the Schedule, Borrower
shall not, without Silicon's prior written consent, do any of the following: (i)
merge or consolidate with another corporation or entity; (ii) acquire any
assets, except in the ordinary course of business; (iii) enter into any other
transaction outside the ordinary course of business; (iv) sell or transfer any
Collateral, except for the sale of finished Inventory in the ordinary course of
Borrower's business, and except for the sale of obsolete or unneeded Equipment
in the ordinary course of business; (v) store any Inventory or other Collateral
with any warehouseman or other third party; (vi) sell any Inventory on a
sale-or-return, guaranteed sale, consignment, or other contingent basis; (vii)
make any loans of any money or other assets; (viii) incur any debts, outside the
ordinary course of business, which would have a material, adverse effect on
Borrower or on the prospect of repayment of the Obligations; (ix) guarantee or
otherwise become liable with respect to the obligations of another party or
entity; (x) pay or declare any dividends on Borrower's stock (except for
dividends payable solely in stock of Borrower); (xi) redeem, retire, purchase or
otherwise acquire, directly or indirectly, any of Borrower's stock; (xii) make
any change in Borrower's capital structure which would have a material adverse
effect on Borrower or on the prospect of repayment of the Obligations; or (xiii)
pay total compensation, including salaries, fees, bonuses, commissions, and all
other payments, whether directly or indirectly, in money or otherwise, to
Borrower's executives, officers and directors (or any relative thereof) in an
amount in excess of the amount set forth on the Schedule; or (xiv) dissolve or
elect to dissolve. Transactions permitted by the foregoing provisions of this
Section are only permitted if no Default or Event of Default would occur as a
result of such transaction.

   5.6 LITIGATION COOPERATION. Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

   5.7 FURTHER ASSURANCES. Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

6.   TERM.

   6.1 MATURITY DATE. This Agreement shall continue in effect until the maturity
date set forth on the Schedule (the "Maturity Date"); provided that the Maturity
Date shall automatically be extended, and this Agreement shall automatically and
continuously renew, for successive additional terms of one year each, unless one
party gives written notice to the other, not less than sixty days prior to the
next Maturity Date, that such party elects to terminate this Agreement effective
on the next Maturity Date.

   6.2 EARLY TERMINATION. This Agreement may be terminated prior to the Maturity
Date as follows: (i) by Borrower, effective three Business Days after written
notice of termination is given to Silicon; or (ii) by Silicon at any time after
the occurrence of an Event of Default, without notice, effective immediately.*
The termination fee shall be due and payable on the effective date of
termination and thereafter shall bear interest at a rate equal to the highest
rate applicable to any of the Obligations.

   *IF THIS AGREEMENT IS TERMINATED BY BORROWER OR BY SILICON UNDER THIS SECTION
6.2 PRIOR TO THE FIRST ANNIVERSARY DATE OF THIS AGREEMENT, BORROWER SHALL PAY TO
SILICON A TERMINATION FEE IN AN AMOUNT EQUAL TO ONE PERCENT (1.0%) OF THE
MAXIMUM CREDIT LIMIT. IF THIS AGREEMENT IS TERMINATED BY BORROWER OR BY SILICON
UNDER THIS SECTION 6.2 AFTER THE FIRST ANNIVERSARY DATE BUT PRIOR TO THE SECOND
ANNIVERSARY DATE OF THIS AGREEMENT, BORROWER SHALL PAY TO SILICON A TERMINATION
FEE IN AN AMOUNT EQUAL TO ONE-HALF OF ONE PERCENT (0.5%) OF THE MAXIMUM CREDIT
LIMIT. NO SUCH TERMINATION FEES SHALL BE CHARGED IF THE CREDIT FACILITY
HEREUNDER IS REPLACED WITH A NEW FACILITY FROM ANOTHER DIVISION OF SILICON
VALLEY BANK.

     6.3 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such Obligations are otherwise then due and payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for re-

effective date or because of the occurrence of an event on or subsequent to the

above cure periods, and thereafter if an Event of Default has occurred.

   7.2 REMEDIES. Upon the occurrence of any Event of Default, and at any time
thereafter, Silicon, at its option, and without notice or demand of any kind
(all of which are hereby expressly waived by Borrower), may do any one or more
of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by
any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (d) Require
Borrower to assemble any or all of the Collateral and make it available to
Silicon at places designated by Silicon which are reasonably convenient to
Silicon and Borrower, and to remove the Collateral to such locations as Silicon
may deem advisable; (e) Complete the processing, manufacturing or repair of any

vehicles, hoists, lifts, cranes, equipment and all other property without
charge; (f) Sell, lease or otherwise dispose of any of the Collateral, in its
condition at the time Silicon obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private sales,

adjourn any such sale from 



                                      -7-

--------------------------------------------------------------------------------



time to time without notice other than oral announcement at the time scheduled
for sale. Silicon shall have the right to conduct such disposition on Borrower's
premises without charge, for such time or times as Silicon deems reasonable, or
on Silicon's premises, or elsewhere and the Collateral need not be located at
the place of disposition. Silicon may directly or through any affiliated company
purchase or lease any Collateral at any such public disposition, and if
permissible under applicable law, at any private disposition. Any sale or other
disposition of Collateral shall not relieve Borrower of any liability Borrower
may have if any Collateral is defective as to title or physical condition or
otherwise at the time of sale; (g) Demand payment of, and collect any
Receivables and General Intangibles comprising Collateral and, in connection
therewith, Borrower irrevocably authorizes Silicon to endorse or sign Borrower's
name on all collections, receipts, instruments and other documents, to take
possession of and open mail addressed to Borrower and remove therefrom payments
made with respect to any item of the Collateral or proceeds thereof, and, in
Silicon's sole discretion, to grant extensions of time to pay, compromise claims
and settle Receivables and the like for less than face value; (h) Offset against
any sums in any of Borrower's general, special or other Deposit Accounts with
Silicon; and (i) Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the preparation
thereof or referring thereto. All reasonable attorneys' fees, expenses, costs,
liabilities and obligations incurred by Silicon with respect to the foregoing
shall be added to and become part of the Obligations, shall be due on demand,
and shall bear interest at a rate equal to the highest interest rate applicable
to any of the Obligations. Without limiting any of Silicon's rights and
remedies, from and after the occurrence of any Event of Default, the interest
rate applicable to the Obligations shall be increased by an additional four
percent per annum.

   7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and Silicon
agree that a sale or other disposition (collectively, "sale") of any Collateral
which complies with the following standards will conclusively be deemed to be
commercially reasonable: (i) Notice of the sale is given to Borrower at least
seven days prior to the sale, and, in the case of a public sale, notice of the
sale is published at least seven days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted; (ii) Notice of the
sale describes the collateral in general, non-specific terms; (iii) The sale is
conducted at a place designated by Silicon, with or without the Collateral being
present; (iv) The sale commences at any time between 8:00 a.m. and 6:00 p.m; (v)
Payment of the purchase price in cash or by cashier's check or wire transfer is
required; (vi) With respect to any sale of any of the Collateral, Silicon may
(but is not obligated to) direct any prospective purchaser to ascertain directly
from Borrower any and all information concerning the same. Silicon shall be free
to employ other methods of noticing and selling the Collateral, in its
discretion, if they are commercially reasonable.

   7.4 POWER OF ATTORNEY. Upon the occurrence of any Event of Default, without
limiting Silicon's other rights and remedies, Borrower grants to Silicon an
irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to
Borrower, and at Borrower's expense, to do any or all of the following, in
Borrower's name or otherwise, but Silicon agrees to exercise the following
powers in a commercially reasonable manner: (a) Execute on behalf of Borrower
any documents that Silicon may, in its sole discretion, deem advisable in order
to perfect and maintain Silicon's security interest in the Collateral, or in
order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral or in which Silicon has an interest; (c) Execute
on behalf of Borrower, any invoices relating to any Receivable, any draft
against any Account Debtor and any notice to any Account Debtor, any proof of
claim in bankruptcy, any Notice of Lien, claim of mechanic's, materialman's or
other lien, or assignment or satisfaction of mechanic's, materialman's or other
lien; (d) Take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into Silicon's
possession; (e) Endorse all checks and other forms of remittances received by
Silicon; (f) Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; (g)
Grant extensions of time to pay, compromise claims and settle Receivables and
General Intangibles for less than face value and execute all releases and other
documents in connection therewith; (h) Pay any sums required on account of
Borrower's taxes or to secure the release of any liens therefor, or both; (i)
Settle and adjust, and give releases of, any insurance claim that relates to any
of the Collateral and obtain payment therefor; (j) Instruct any third party
having custody or control of any books or records belonging to, or relating to,
Borrower to give Silicon the same rights of access and other rights with respect
thereto as Silicon has under this Agreement; and (k) Take any action or pay any
sum required of Borrower pursuant to this Agreement and any other present or
future agreements. Any and all reasonable sums paid and any and all reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon with respect to the foregoing shall be added to and become part of the
Obligations, shall be payable on demand, and shall bear interest at a rate equal
to the highest interest rate applicable to any of the Obligations. In no event
shall Silicon's rights under the foregoing power of attorney or any of Silicon's
other rights under this Agreement be deemed to indicate that Silicon is in
control of the business, management or properties of Borrower.

   7.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of any sale
of the Collateral shall be applied by Silicon first to the reasonable costs,
expenses, liabilities, obligations and attorneys' fees incurred by Silicon in
the exercise of its rights under this Agreement, second to the interest due upon
any of the Obligations, and third to the principal of the Obligations, in such
order as Silicon shall determine in its sole discretion. Any surplus shall be
paid to Borrower or other persons legally entitled thereto; 



                                      -8-

SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------



Borrower shall remain liable to Silicon for any deficiency. If, Silicon, in its
sole discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring
the reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

   7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set forth in
this Agreement, Silicon shall have all the other rights and remedies accorded a
secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

8. DEFINITIONS. As used in this Agreement, the following terms have the
following meanings:

   "Account Debtor" means the obligor on a Receivable.

   "Affiliate" means, with respect to any Person, a relative, partner,
shareholder, director, officer, or employee of such Person, or any parent or
subsidiary of such Person, or any Person controlling, controlled by or under

Borrower's business from the sale of goods or rendition of services, which
Silicon, in its sole judgment, shall deem eligible for borrowing, based on such
considerations as Silicon may from time to time deem appropriate. Without
limiting the fact that the determination of which Receivables are eligible for
borrowing is a matter of Silicon's discretion, the following (the "Minimum
Eligibility Requirements") are the minimum requirements for a Receivable to be
an Eligible Receivable: (i) the Receivable must not be outstanding for more than
90 days from its invoice date, (ii) the Receivable must not represent progress
billings, or be due under a fulfillment or requirements contract with the
Account Debtor, (iii) the Receivable must not be subject to any contingencies
(including Receivables arising from sales on consignment, guaranteed sale or
other terms pursuant to which payment by the Account Debtor may be conditional),
(iv) the Receivable must not be owing from an Account Debtor with whom the
Borrower has any dispute (whether or not relating to the particular Receivable),
(v) the Receivable must not be owing from an Affiliate of Borrower, (vi) the

insolvency or bankruptcy proceeding, or whose financial condition is not

business, (vii) the Receivable must not be owing from the United States or any
department, agency or instrumentality thereof (unless there has been compliance,
to Silicon's satisfaction, with the United States Assignment of Claims Act),
(viii) the Receivable must not be owing from an Account Debtor located outside
the United States or Canada (unless pre-approved by Silicon in its discretion in
writing, or backed by a letter of credit satisfactory to Silicon, or FCIA
insured satisfactory to Silicon), (ix) the Receivable must not be owing from an
Account Debtor to whom Borrower is or may be liable for goods purchased from
such Account Debtor or otherwise. Receivables owing from one Account Debtor will
not be deemed Eligible Receivables to the extent they exceed 25% of the total
eligible Receivables outstanding*. In addition, if more than 50% of the
Receivables owing from an Account Debtor are outstanding more than 90 days from
their invoice date (without regard to unapplied credits) or are otherwise not
eligible Receivables, then all Receivables owing from that Account Debtor will
be deemed ineligible for borrowing. Silicon may, from time to time, in its

faith, do or may affect either (i) the Collateral or any other property which is

   9.1 INTEREST COMPUTATION. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after
receipt by Silicon of immediately available funds, and, for purposes of the
foregoing, any such funds received after 12:00 Noon on any day shall be deemed
received on the next Business Day. Silicon shall not, however, be required to

unsatisfactory to Silicon in its sole discretion, and Silicon may charge
Borrower's loan 



                                      -10-

--------------------------------------------------------------------------------



account for the amount of any item of payment which is returned to Silicon
unpaid.

   9.2 APPLICATION OF PAYMENTS. All payments with respect to the Obligations may
be applied, and in Silicon's sole discretion reversed and re-applied, to the
Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

   9.3 CHARGES TO ACCOUNTS. Silicon may, in its discretion, require that
Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans. Silicon may also, in its discretion, charge any
monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

   9.4 MONTHLY ACCOUNTINGS. Silicon shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Silicon), unless Borrower
notifies Silicon in writing to the contrary within thirty days after each
account is rendered, describing the nature of any alleged errors or admissions.

   9.5 NOTICES. All notices to be given under this Agreement shall be in writing
and shall be given either personally or by reputable private delivery service or
by regular first-class mail, or certified mail return receipt requested,
addressed to Silicon or Borrower at the addresses shown in the heading to this
Agreement, or at any other address designated in writing by one party to the
other party. Notices to Silicon shall be directed to the Commercial Finance
Division, to the attention of the Division Manager or the Division Credit
Manager. All notices shall be deemed to have been given upon delivery in the
case of notices personally delivered, or at the expiration of one Business Day
following delivery to the private delivery service, or two Business Days
following the deposit thereof in the United States mail, with postage prepaid.

   9.6 SEVERABILITY. Should any provision of this Agreement be held by any court
of competent jurisdiction to be void or unenforceable, such defect shall not
affect the remainder of this Agreement, which shall continue in full force and
effect.

   9.7 INTEGRATION. This Agreement and such other written agreements, documents
and instruments as may be executed in connection herewith are the final, entire
and complete agreement between Borrower and Silicon and supersede all prior and
contemporaneous negotiations and oral representations and agreements, all of
which are merged and integrated in this Agreement. There are no oral
understandings, representations or agreements between the parties which are not
set forth in this Agreement or in other written agreements signed by the parties
in connection herewith.

   9.8 WAIVERS. The failure of Silicon at any time or times to require Borrower
to strictly comply with any of the provisions of this Agreement or any other
present or future agreement between Borrower and Silicon shall not waive or
diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any
action taken by Silicon, unless expressly required by this Agreement.

   9.9 NO LIABILITY FOR ORDINARY NEGLIGENCE. Neither Silicon, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other party through the ordinary negligence of Silicon, or any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon, but nothing herein shall relieve Silicon from
liability for its own gross negligence or willful misconduct.

   9.10 AMENDMENT. The terms and provisions of this Agreement may not be waived
or amended, except in a writing executed by Borrower and a duly authorized
officer of Silicon.

   9.11 TIME OF ESSENCE. Time is of the essence in the performance by Borrower
of each and every obligation under this Agreement.

   9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute

hereunder to reimburse Silicon for attorneys fees, Borrower may, for
convenience, issue checks directly to Silicon's attorneys, Levy, Small & Lallas,
but Borrower acknowledges and agrees that Levy, Small & Lallas is representing
only Silicon and not Borrower in connection with this Agreement. If either
Silicon or Borrower files any lawsuit against the other predicated on a breach

action shall be entitled to recover its reasonable costs and attorneys' fees,
including (but not limited to) reasonable attorneys' fees and costs incurred in
the enforcement of, execution upon or defense of any order, decree, award or
judgment. All attorneys' fees and costs to which Silicon may be entitled
pursuant to this Paragraph shall immediately become part of Borrower's
Obligations, shall be due on demand, and shall bear interest at a rate equal to
the highest interest rate applicable to any of the Obligations.

   9.13 BENEFIT OF AGREEMENT. The provisions of this Agreement shall be binding
upon and inure to the benefit of the respective successors, assigns, heirs,
beneficiaries and representatives of Borrower and Silicon; provided, however,
that Borrower may not assign or transfer any of its rights under this Agreement
without the prior written consent of Silicon, and any prohibited assignment
shall be void. No consent by Silicon to any assignment shall release Borrower
from its liability for the Obligations.

   9.14 JOINT AND SEVERAL LIABILITY. If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

   9.15 LIMITATION OF ACTIONS. Any claim or cause of action by Borrower against
Silicon, its directors, officers, employees, agents, accountants or attorneys,
based upon, arising from, or relating to this Loan Agreement, or any other
present or future document or agreement, or any other transaction contemplated
hereby or thereby or relating hereto or thereto, or any other matter, cause or
thing whatsoever, occurred, done, omitted or suffered to be done by Silicon, its
directors, officers, employees, agents, accountants or attorneys, shall be
barred unless asserted by Borrower by the commencement of an action or
proceeding in a court of competent jurisdiction by the filing of a complaint
within one year after the first act, occurrence or omission upon which such
claim or cause of action, or any part thereof, is based, and the service of a
summons and complaint on an officer of Silicon, or on any other person
authorized to accept service on behalf of Silicon, within thirty (30) days
thereafter. Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Silicon in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

   9.16 PARAGRAPH HEADINGS; CONSTRUCTION. Paragraph headings are only used in
this Agreement for convenience. Borrower and Silicon acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,
define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Silicon or Borrower under any rule
of construction or otherwise.

   9.17 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and Borrower
shall be governed by the laws of the State of California. As a material part of
the consideration to Silicon to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Silicon's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Santa Clara County;
(ii) consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or any
other method permitted by law; and (iii) waives any and all rights Borrower may
have to object to the jurisdiction of any such court, or to transfer or change
the venue of any such action or proceeding.

RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF,
OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE

     LETTER OF CREDIT SUBLIMIT
     (Section 1.5):                     $4,000,000.

     FOREIGN EXCHANGE
     CONTRACT SUBLIMIT                  Up to $4,000,000 of the Credit Limit
                                        (the "Contract Limit") may be utilized
                                        for spot and future foreign exchange
                                        contracts (the "Exchange Contracts").
                                        The Credit Limit at any time shall be
                                        reduced by the following amounts (the
                                        "Foreign Exchange Reserve") on each day
                                        (the "Determination Date"): (i) on all
                                        outstanding Exchange Contracts on which
                                        delivery is to be effected or settlement
                                        allowed more than two business days from
                                        the Determination Date, 10% of the gross
                                        amount of the Exchange Contracts; plus
                                        (ii) on all outstanding Exchange
                                        Contracts on which delivery is to be
                                        effected or settlement allowed within
                                        two business days after the
                                        Determination Date, 100% of the gross
                                        amount of the Exchange Contracts. In
                                        lieu of the Foreign Exchange Reserve for
                                        100% of the gross amount of any Exchange
                                        Contract, the Borrower may request that
                                        Silicon debit the Borrower's bank
                                        account with Silicon for such amount,
                                        provided Borrower has immediately
                                        available funds in such amount in its
                                        bank account.

                                        Silicon may, in its discretion,
                                        terminate the Exchange Contracts at any
                                        time (a) that an Event of Default occurs
                                        or (b) that there is not sufficient
                                        availability under the Credit Limit and
                                        Borrower does not have available funds
                                        in its bank account to satisfy the
                                        Foreign Exchange Reserve. If either
                                        Silicon or Borrower terminates the
                                        Exchange Contracts, and without
                                        limitation of the FX Indemnity
                                        Provisions (as referred to below),
                                        Borrower agrees to reimburse Silicon for
                                        any and all fees, costs and expenses
                                        relating thereto or arising in
                                        connection therewith.

                                        Borrower shall not permit the total
                                        gross amount of all Exchange Contracts
                                        on which delivery is to be effected and

                                        than $2,000,000 (the "Settlement
                                        Limit"), nor shall Borrower permit the
                                        total gross amount of all Exchange
                                        Contracts to which Borrower is a party,
                                        outstanding at any one time, to exceed
                                        the Contract Limit.

                                        Notwithstanding the above, however, the
                                        amount which may be settled in any two

                                        Silicon's sole discretion, be increased
                                        above the Settlement Limit up to, but in
                                        no event to exceed, the amount of the

                                            in the amount of the Foreign
                                            Exchange Reserve as of each
                                            Determination Date, and Silicon in

                                            amount of the Foreign Exchange
                                            Reserve against the Credit Limit; or

                                            (ii) if there is insufficient
                                            availability under the Credit Limit
                                            as to settlements within any two (2)

                                            is able to: (A) verify good funds
                                            overseas prior to crediting
                                            Borrower's deposit account with
                                            Silicon (in the case of Borrower's
                                            sale of foreign currency); or (B)
                                            debit Borrower's deposit account
                                            with Silicon prior to delivering
                                            foreign currency overseas (in the
                                            case of Borrower's purchase of
                                            foreign currency);

                                        Provided that it is expressly understood
                                        that Silicon's willingness to adopt the
                                        Discretionary Settlement Amount is a
                                        matter of Silicon's sole discretion and
                                        the existence of the Discretionary
                                        Settlement Circumstances in no way means
                                        or implies that Silicon shall be
                                        obligated to permit the Borrower to
                                        exceed the Settlement Limit in any two
                                        business day period.

                                        In the case of Borrower's purchase of
                                        foreign currency, Borrower shall
                                        instruct Silicon in advance upon
                                        settlement either to treat the
                                        settlement amount as an advance under
                                        the Credit Limit, or to debit Borrower's
                                        account for the amount settled.

                                        The Borrower shall execute all standard
                                        form applications and agreements of
                                        Silicon in connection with the Exchange
                                        Contracts, and without limiting any of
                                        the terms of such applications and
                                        agreements, the Borrower will pay all
                                        standard fees and charges of Silicon in
                                        connection with the Exchange Contracts.

                                        Without limiting any of the other terms

2.  INTEREST.

         INTEREST RATE (Section 1.2):

                                        A rate equal to the "Prime Rate" in
                                        effect from time to time, plus 1.0% per
                                        annum. Interest shall be calculated on
                                        the basis of a 360-day year for the
                                        actual number of days elapsed. "Prime
                                        Rate" means the rate announced from time
                                        to time by Silicon as its "prime rate;"
                                        it is a base rate upon which other rates
                                        charged by Silicon are based, and it is
                                        not necessarily the best rate available
                                        at Silicon. The interest rate applicable
                                        to the Obligations shall change on each
                                        date there is a change in the Prime
                                        Rate.

SILICON VALLEY BANK
                           LOAN AND SECURITY AGREEMENT

                                 (EXIM PROGRAM)

BORROWER:         AG ASSOCIATES
ADDRESS:          4425 FORTRAN DRIVE
                  SAN JOSE, CA  95134

DATE:             JUNE 23, 1998


THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK, COMMERCIAL FINANCE DIVISION ("Silicon"), whose address is
3003 Tasman Drive, Santa Clara, California 95054 and the borrower(s) named above
(jointly and severally, the "Borrower"), whose chief executive office is located
at the above address ("Borrower's Address"). The Schedule to this Agreement (the
"Schedule") shall for all purposes be deemed to be a part of this Agreement, and
the same is an integral part of this Agreement. (Definitions of certain terms
used in this Agreement are set forth in Section 8 below.)


1.   LOANS.

   1.1 LOANS. Silicon will make loans to Borrower (the "Loans"), in amounts
determined by Silicon in its sole discretion, up to the amounts (the "Credit
Limit") shown on the Schedule, provided no Default or Event of Default has
occurred and is continuing, and subject to deduction of any Reserves for accrued
interest and such other Reserves as Silicon deems proper from time to time.

   1.2 INTEREST. All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement. Interest shall be payable monthly, on the last
day of the month. Interest may, in Silicon's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Silicon may, in its discretion, charge interest to
Borrower's Deposit Accounts maintained with Silicon. Regardless of the amount of
Obligations that may be outstanding from time to time, Borrower shall pay
Silicon minimum monthly interest during the term of this Agreement in the amount
set forth on the Schedule (the "Minimum Monthly Interest").

   1.3 OVERADVANCES. If at any time or for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit (an
"Overadvance"), Borrower shall immediately pay the amount of the excess to
Silicon, without notice or demand. Without limiting Borrower's obligation to
repay to Silicon on demand the amount of any Overadvance, Borrower agrees to pay
Silicon interest on the outstanding amount of any Overadvance, on demand, at a
rate equal to the interest rate which would otherwise be applicable to the
Overadvance, plus an additional 2% per annum.

   1.4 FEES. Borrower shall pay Silicon the fee(s) shown on the Schedule, which
are in addition to all interest and other sums payable to Silicon and are not
refundable.

   1.5 LETTERS OF CREDIT. At the request of Borrower, Silicon may, in its sole
discretion, issue or arrange for the issuance of letters of credit for the
account of Borrower, in each case in form and substance satisfactory to Silicon
in its sole discretion (collectively, "Letters of Credit"). The aggregate face
amount of all outstanding Letters of Credit from time to time shall not exceed
the amount shown on the Schedule (the "Letter of Credit Sublimit"), and shall be
reserved against Loans which would otherwise be available hereunder. Borrower
shall pay all bank charges (including charges of Silicon) for the issuance of
Letters of Credit, together with such additional fee as Silicon's letter of
credit department shall charge in connection with the issuance of the Letters of
Credit. Any payment by Silicon under or in connection with a Letter of Credit
shall constitute a Loan hereunder on the date such payment is made. Each Letter
of Credit shall have an expiry date no later than thirty days prior to the
Maturity Date. Borrower hereby agrees to indemnify, save, and hold Silicon
harmless from any loss, cost, expense, or liability, including payments made by
Silicon, expenses, and reasonable attorneys' fees incurred by Silicon arising
out of or in connection with any Letters of Credit. Borrower agrees to be bound
by the regulations and interpretations of the issuer of any Letters of Credit
guarantied by Silicon and opened for Borrower's account or by Silicon's
interpretations of any Letter of Credit issued by Silicon for Borrower's
account, and Borrower understands and agrees that Silicon shall not be liable
for any error, negligence, or mistake, whether of omission or commission, in
following Borrower's instructions or those contained in the Letters of Credit or
any modifications, amendments, or supplements thereto. Borrower

<PAGE>   25
SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------


understands that Letters of Credit may require Silicon to indemnify the issuing
bank for certain costs or liabilities arising out of claims by Borrower against
such issuing bank. Borrower hereby agrees to indemnify and hold Silicon harmless
with respect to any loss, cost, expense, or liability incurred by Silicon under
any Letter of Credit as a result of Silicon's indemnification of any such
issuing bank. The provisions of this Loan Agreement, as it pertains to Letters
of Credit, and any other present or future documents or agreements between
Borrower and Silicon relating to Letters of Credit are cumulative.

2.  SECURITY INTEREST.

   2.1 SECURITY INTEREST. To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to Silicon a security interest in
all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located (collectively, the "Collateral"): All Inventory,
Equipment, Receivables, and General Intangibles, including, without limitation,
all of Borrower's Deposit Accounts, and all money, and all property now or at
any time in the future in Silicon's possession (including claims and credit
balances), and all proceeds (including proceeds of any insurance policies,
proceeds of proceeds and claims against third parties), all products and all
books and records related to any of the foregoing (all of the foregoing,
together with all other property in which Silicon may now or in the future be
granted a lien or security interest, is referred to herein, collectively, as the
"Collateral").

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

   In order to induce Silicon to enter into this Agreement and to make Loans,
Borrower represents and warrants to Silicon as follows, and Borrower covenants
that the following representations will continue to be true, and that Borrower
will at all times comply with all of the following covenants:

   3.1 CORPORATE EXISTENCE AND AUTHORITY. Borrower, if a corporation, is and
will continue to be, duly organized, validly existing and in good standing under
the laws of the jurisdiction of its incorporation. Borrower is and will continue
to be qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a material adverse effect on Borrower. The
execution, delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (i) have been duly and validly authorized, (ii)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (iii) do not violate Borrower's articles or certificate
of incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (iv) do not
constitute grounds for acceleration of any material indebtedness or obligation
under any material agreement or instrument which is binding upon Borrower or its
property.

   3.2 NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in the
heading to this Agreement is its correct name. Listed on the Schedule are all
prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Silicon 30 days' prior written notice before changing its
name or doing business under any other name. Borrower has complied, and will in
the future comply, with all laws relating to the conduct of business under a
fictitious business name.

   3.3 PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth in the
heading to this Agreement is Borrower's chief executive office. In addition,
Borrower has places of business and Collateral is located only at the locations
set forth on the Schedule. Borrower will give Silicon at least 30 days prior
written notice before opening any additional place of business, changing its
chief executive office, or moving any of the Collateral to a location other than
Borrower's Address or one of the locations set forth on the Schedule.

   3.4 TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower. The Collateral now is and will remain
free and clear of any and all liens, charges, security interests, encumbrances
and adverse claims, except for Permitted Liens. Silicon now has, and will
continue to have, a first-priority perfected and enforceable security interest
in all of the Collateral, subject only to the Permitted Liens, and Borrower will
at all times defend Silicon and the Collateral against all claims of others.
None of the Collateral now is or will be affixed to any real property in such a
manner, or with such intent, as to become a fixture. Borrower is not and will
not become a lessee under any real property lease pursuant to which the lessor
may obtain any rights in any of the Collateral and no such lease now prohibits,
restrains, impairs or will prohibit, restrain or impair Borrower's right to
remove any Collateral from the leased premises. Whenever any Collateral is
located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Silicon, use its best efforts to cause
such third party to execute and deliver to Silicon, in form acceptable to
Silicon, such waivers and subordinations as Silicon shall specify, so as to
ensure that Silicon's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. Borrower will keep in full force
and effect, and will comply with all the terms of, any lease of real property
where any of the Collateral now or in the future may be located.

   3.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral in good
working condition, and Borrower will not use the Collateral for any unlawful
purpose. Borrower will immediately advise Silicon in writing of any material
loss or damage to the Collateral.

   3.6 BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

   3.7 FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial statements now
or in the future delivered to Silicon have been, and will be, prepared in
conformity with generally accepted accounting principles and now and in the
future will completely and accurately reflect the financial condition of
Borrower, at the times and for the periods therein stated. Between the last date
covered by any such statement provided to Silicon and the date 



                                       -3-
<PAGE>   26

hereof, there has been no material adverse change in the financial condition or
business of Borrower. Borrower is now and will continue to be solvent.

   3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has timely
filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and Borrower has timely paid, and will timely pay,
all foreign, federal, state and local taxes, assessments, deposits and
contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Silicon in
writing of the commencement of, and any material development in, the
proceedings, and (iii) posts bonds or takes any other steps required to keep the
contested taxes from becoming a lien upon any of the Collateral. Borrower is
unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.
Borrower shall, at all times, utilize the services of an outside payroll service
providing for the automatic deposit of all payroll taxes payable by Borrower.

   3.9 COMPLIANCE WITH LAW. Borrower has complied, and will comply, in all
material respects, with all provisions of all foreign, federal, state and local
laws and regulations relating to Borrower, including, but not limited to, those
relating to Borrower's ownership of real or personal property, the conduct and
licensing of Borrower's business, and all environmental matters.

   3.10 LITIGATION. Except as disclosed in the Schedule, there is no claim,
suit, litigation, proceeding or investigation pending or (to best of Borrower's
knowledge) threatened by or against or affecting Borrower in any court or before
any governmental agency (or any basis therefor known to Borrower) which may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform Silicon in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of
$50,000 or more, or involving $100,000 or more in the aggregate.

   3.11 USE OF PROCEEDS. All proceeds of all Loans shall be used solely for
lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation U of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

4.  RECEIVABLES.

   4.1 REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and warrants
to Silicon as follows: Each Receivable with respect to which Loans are requested
by Borrower shall, on the date each Loan is requested and made, (i) represent an
undisputed bona fide existing unconditional obligation of the Account Debtor
created by the sale, delivery, and acceptance of goods or the rendition of
services in the ordinary course of Borrower's business, and (ii) meet the
Minimum Eligibility Requirements set forth in Section 8 below.

   4.2 REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. Borrower
represents and warrants to Silicon as follows: All statements made and all
unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be,
and all signatories and endorsers have the capacity to contract. All sales and
other transactions underlying or giving rise to each Receivable shall fully
comply with all applicable laws and governmental rules and regulations. All
signatures and endorsements on all documents, instruments, and agreements
relating to all Receivables are and shall be genuine, and all such documents,
instruments and agreements are and shall be legally enforceable in accordance
with their terms.

   4.3 SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES. Borrower shall deliver
to Silicon transaction reports and loan requests, schedules and assignments of
all Receivables, and schedules of collections, all on Silicon's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Silicon's security interest and other rights in all of
Borrower's Receivables, nor shall Silicon's failure to advance or lend against a
specific Receivable affect or limit Silicon's security interest and other rights
therein. Loan requests received after 12:00 Noon will not be considered by
Silicon until the next Business Day. Together with each such schedule and
assignment, or later if requested by Silicon, Borrower shall furnish Silicon
with copies (or, at Silicon's request, originals) of all contracts, orders,
invoices, and other similar documents, and all original shipping instructions,
delivery receipts, bills of lading, and other evidence of delivery, for any
goods the sale or disposition of which gave rise to such Receivables, and
Borrower warrants the genuineness of all of the foregoing. Borrower shall also
furnish to Silicon an aged accounts receivable trial balance in such form and at
such intervals as Silicon shall request. In addition, Borrower shall deliver to
Silicon the originals of all instruments, chattel paper, security agreements,
guarantees and other documents and property evidencing or securing any
Receivables, immediately upon receipt thereof and in the same form as received,
with all necessary indorsements, all of which shall be with recourse. Borrower
shall also provide Silicon with copies of all credit memos within two days after
the date issued.

   4.4 COLLECTION OF RECEIVABLES. Borrower shall have the right to collect all
Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Silicon, and Borrower shall immediately deliver all such payments and proceeds
to Silicon in their original form, 



                                      -4-

--------------------------------------------------------------------------------


duly endorsed in blank, to be applied to the Obligations in such order as
Silicon shall determine. Silicon may, in its discretion, require that all
proceeds of Collateral be deposited by Borrower into a lockbox account, or such
other "blocked account" as Silicon may specify, pursuant to a blocked account
agreement in such form as Silicon may specify. Silicon or its designee may, at
any time, notify Account Debtors that the Receivables have been assigned to
Silicon.

   4.5. REMITTANCE OF PROCEEDS. All proceeds arising from the disposition of any
Collateral shall be delivered, in kind, by Borrower to Silicon in the original
form in which received by Borrower not later than the following Business Day
after receipt by Borrower, to be applied to the Obligations in such order as
Silicon shall determine; provided that, if no Default or Event of Default has
occurred, Borrower shall not be obligated to remit to Silicon the proceeds of
the sale of worn out or obsolete equipment disposed of by Borrower in good faith
in an arm's length transaction for an aggregate purchase price of $25,000 or
less (for all such transactions in any fiscal year). Borrower agrees that it
will not commingle proceeds of Collateral with any of Borrower's other funds or
property, but will hold such proceeds separate and apart from such other funds
and property and in an express trust for Silicon. Nothing in this Section limits
the restrictions on disposition of Collateral set forth elsewhere in this
Agreement.

   4.6 DISPUTES. Borrower shall notify Silicon promptly of all disputes or
claims relating to Receivables. Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Silicon on the regular reports provided to Silicon; (ii) no Default
or Event of Default has occurred and is continuing; and (iii) taking into
account all such discounts settlements and forgiveness, the total outstanding
Loans will not exceed the Credit Limit. Silicon may, at any time after the
occurrence of an Event of Default, settle or adjust disputes or claims directly
with Account Debtors for amounts and upon terms which Silicon considers
advisable in its reasonable credit judgment and, in all cases, Silicon shall
credit Borrower's Loan account with only the net amounts received by Silicon in
payment of any Receivables.

   4.7 RETURNS. Provided no Event of Default has occurred and is continuing, if
any Account Debtor returns any Inventory to Borrower in the ordinary course of
its business, Borrower shall promptly determine the reason for such return and
promptly issue a credit memorandum to the Account Debtor in the appropriate
amount (sending a copy to Silicon). In the event any attempted return occurs
after the occurrence of any Event of Default, Borrower shall (i) hold the
returned Inventory in trust for Silicon, (ii) segregate all returned Inventory
from all of Borrower's other property, (iii) conspicuously label the returned
Inventory as Silicon's property, and (iv) immediately notify Silicon of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Silicon's request deliver such
returned Inventory to Silicon.

   4.8 VERIFICATION. Silicon may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or Silicon or such other name as Silicon may choose.

   4.9 NO LIABILITY. Silicon shall not under any circumstances be responsible or
liable for any shortage or discrepancy in, damage to, or loss or destruction of,
any goods, the sale or other disposition of which gives rise to a Receivable, or
for any error, act, omission, or delay of any kind occurring in the settlement,
failure to settle, collection or failure to collect any Receivable, or for
settling any Receivable in good faith for less than the full amount thereof, nor
shall Silicon be deemed to be responsible for any of Borrower's obligations
under any contract or agreement giving rise to a Receivable. Nothing herein
shall, however, relieve Silicon from liability for its own gross negligence or
willful misconduct.

5.  ADDITIONAL DUTIES OF THE BORROWER.

   5.1 FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply with
the financial and other covenants set forth in the Schedule.

   5.2 INSURANCE. Borrower shall, at all times insure all of the tangible
personal property Collateral and carry such other business insurance, with
insurers reasonably acceptable to Silicon, in such form and amounts as Silicon
may reasonably require, and Borrower shall provide evidence of such insurance to
Silicon, so that Silicon is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies shall name Silicon as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Silicon. Upon receipt of the proceeds of any such
insurance, Silicon shall apply such proceeds in reduction of the Obligations as
Silicon shall determine in its sole discretion, except that, provided no Default
or Event of Default has occurred and is continuing, Silicon shall release to
Borrower insurance proceeds with respect to Equipment totaling less than
$100,000, which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid. Silicon may
require reasonable assurance that the insurance proceeds so released will be so
used. If Borrower fails to provide or pay for any insurance, Silicon may, but is
not obligated to, obtain the same at Borrower's expense. Borrower shall promptly
deliver to Silicon copies of all reports made to insurance companies.

   5.3 REPORTS. Borrower, at its expense, shall provide Silicon with the written
reports set forth in the Schedule, and such other written reports with respect
to Borrower (including budgets, sales projections, operating plans and other
financial documentation), as Silicon shall from time to time reasonably specify.

   5.4 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times, and on one
Business Day's notice, Silicon, or its agents, shall have the right to inspect
the Collateral, and the right to audit and copy Borrower's books and records.
Silicon shall take reasonable steps to keep confidential all information
obtained in any such inspection or audit, but Silicon shall have the right to
disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. 



                                       -5-
<PAGE>   28
SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------



The foregoing inspections and audits shall be at Borrower's expense and the
charge therefor shall be $500 per person per day (or such higher amount as shall
represent Silicon's then current standard charge for the same), plus reasonable
out of pocket expenses. Borrower will not enter into any agreement with any
accounting firm, service bureau or third party to store Borrower's books or
records at any location other than Borrower's Address, without first obtaining
Silicon's written consent, which may be conditioned upon such accounting firm,
service bureau or other third party agreeing to give Silicon the same rights
with respect to access to books and records and related rights as Silicon has
under this Loan Agreement. Borrower waives the benefit of any accountant-client
privilege or other evidentiary privilege precluding or limiting the disclosure,
divulgence or delivery of any of its books and records (except that Borrower
does not waive any attorney-client privilege).

   5.5 NEGATIVE COVENANTS. Except as may be permitted in the Schedule, Borrower
shall not, without Silicon's prior written consent, do any of the following: (i)
merge or consolidate with another corporation or entity; (ii) acquire any
assets, except in the ordinary course of business; (iii) enter into any other
transaction outside the ordinary course of business; (iv) sell or transfer any
Collateral, except for the sale of finished Inventory in the ordinary course of
Borrower's business, and except for the sale of obsolete or unneeded Equipment
in the ordinary course of business; (v) store any Inventory or other Collateral
with any warehouseman or other third party; (vi) sell any Inventory on a
sale-or-return, guaranteed sale, consignment, or other contingent basis; (vii)
make any loans of any money or other assets; (viii) incur any debts, outside the
ordinary course of business, which would have a material, adverse effect on
Borrower or on the prospect of repayment of the Obligations; (ix) guarantee or
otherwise become liable with respect to the obligations of another party or
entity; (x) pay or declare any dividends on Borrower's stock (except for
dividends payable solely in stock of Borrower); (xi) redeem, retire, purchase or
otherwise acquire, directly or indirectly, any of Borrower's stock; (xii) make
any change in Borrower's capital structure which would have a material adverse
effect on Borrower or on the prospect of repayment of the Obligations; or (xiii)
pay total compensation, including salaries, fees, bonuses, commissions, and all
other payments, whether directly or indirectly, in money or otherwise, to
Borrower's executives, officers and directors (or any relative thereof) in an
amount in excess of the amount set forth on the Schedule; or (xiv) dissolve or
elect to dissolve. Transactions permitted by the foregoing provisions of this
Section are only permitted if no Default or Event of Default would occur as a
result of such transaction.

   5.6 LITIGATION COOPERATION. Should any third-party suit or proceeding be
instituted by or against Silicon with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to Silicon, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Silicon may deem them reasonably necessary in order
to prosecute or defend any such suit or proceeding.

   5.7 FURTHER ASSURANCES. Borrower agrees, at its expense, on request by
Silicon, to execute all documents and take all actions, as Silicon, may deem
reasonably necessary or useful in order to perfect and maintain Silicon's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

6.   TERM.

   6.1 MATURITY DATE. This Agreement shall continue in effect until the maturity
date set forth on the Schedule (the "Maturity Date"); provided that the Maturity
Date shall automatically be extended, and this Agreement shall automatically and
continuously renew, for successive additional terms of one year each, unless one
party gives written notice to the other, not less than sixty days prior to the
next Maturity Date, that such party elects to terminate this Agreement effective
on the next Maturity Date.

   6.2 EARLY TERMINATION. This Agreement may be terminated prior to the Maturity
Date as follows: (i) by Borrower, effective three Business Days after written
notice of termination is given to Silicon; or (ii) by Silicon at any time after
the occurrence of an Event of Default, without notice, effective immediately. If
this Agreement is terminated by Borrower or by Silicon under this Section 6.2,
Borrower shall pay to Silicon a termination fee in an amount equal to two
percent (2.0%) of the Maximum Credit Limit. The termination fee shall be due and
payable on the effective date of termination and thereafter shall bear interest
at a rate equal to the highest rate applicable to any of the Obligations.

   6.3 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier effective
date of termination, Borrower shall pay and perform in full all Obligations,
whether evidenced by installment notes or otherwise, and whether or not all or
any part of such Obligations are otherwise then due and payable. Without
limiting the generality of the foregoing, if on the Maturity Date, or on any
earlier effective date of termination, there are any outstanding Letters of
Credit issued by Silicon or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Silicon,
then on such date Borrower shall provide to Silicon cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Silicon's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Silicon, Silicon may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right or
remedy of Silicon, nor shall any such termination relieve Borrower of any
Obligation to Silicon, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Silicon shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Silicon's security interests.

7.  EVENTS OF DEFAULT AND REMEDIES.

   7.1 EVENTS OF DEFAULT. The occurrence of any of the following events shall
constitute an "Event of Default" under this Agreement, and Borrower shall give
Silicon

obligation secured by a Permitted Lien, which is not cured within any applicable

future in effect; or (j) the commencement of any proceeding against Borrower or
any guarantor of any of the Obligations under any reorganization, bankruptcy,
insolvency, arrangement, readjustment of debt, dissolution or liquidation law or

guaranty of the Obligations or any attempt to do any of the foregoing, or

bankruptcy or insolvency law; or (m) Borrower makes any payment on account of
any indebtedness or obligation which has been subordinated to the Obligations
other than as permitted in the applicable subordination agreement, or if any

any way limits his subordination agreement; or (n) there shall be a change in
the record or beneficial ownership of an aggregate of more than 20% of the
outstanding shares of stock of Borrower, in one or more transactions, compared

date hereof, without the prior written consent of Silicon; or (o) Borrower shall
generally not pay its debts as they become due, or Borrower shall conceal,
remove or transfer any part of its property, with intent to hinder, delay or
defraud its creditors, or make or suffer any transfer of any of its property

law; or (p) there shall be a material adverse change in Borrower's business or
financial condition; or (q) Silicon, acting in good faith and in a commercially
reasonable manner, deems itself insecure because of the occurrence of an event
prior to the effective date hereof of which Silicon had no knowledge on the
effective date or because of the occurrence of an event on or subsequent to the
effective date. Silicon may cease making any Loans hereunder during any of the
above cure periods, and thereafter if an Event of Default has occurred.

   7.2 REMEDIES. Upon the occurrence of any Event of Default, and at any time
thereafter, Silicon, at its option, and without notice or demand of any kind
(all of which are hereby expressly waived by Borrower), may do any one or more
of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by

any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Silicon without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Silicon deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Silicon seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Silicon retain possession of, and not

condition at the time Silicon obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private sales,

adjourn any such sale from time to time without notice other than oral
announcement at the time scheduled for sale. Silicon shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Silicon deems reasonable, or on Silicon's premises, or elsewhere and
the Collateral need not be located at the place of disposition. Silicon may
directly or through any affiliated company

--------------------------------------------------------------------------------



purchase or lease any Collateral at any such public disposition, and if
permissible under applicable law, at any private disposition. Any sale or other
disposition of Collateral shall not relieve Borrower of any liability Borrower
may have if any Collateral is defective as to title or physical condition or
otherwise at the time of sale; (g) Demand payment of, and collect any
Receivables and General Intangibles comprising Collateral and, in connection
therewith, Borrower irrevocably authorizes Silicon to endorse or sign Borrower's
name on all collections, receipts, instruments and other documents, to take
possession of and open mail addressed to Borrower and remove therefrom payments
made with respect to any item of the Collateral or proceeds thereof, and, in

and settle Receivables and the like for less than face value; (h) Offset against
any sums in any of Borrower's general, special or other Deposit Accounts with
Silicon; and (i) Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the preparation

and shall bear interest at a rate equal to the highest interest rate applicable
to any of the Obligations. Without limiting any of Silicon's rights and
remedies, from and after the occurrence of any Event of Default, the interest
rate applicable to the Obligations shall be increased by an additional four
percent per annum.

   7.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and Silicon
agree that a sale or other disposition (collectively, "sale") of any Collateral
which complies with the following standards will conclusively be deemed to be
commercially reasonable: (i) Notice of the sale is given to Borrower at least
seven days prior to the sale, and, in the case of a public sale, notice of the
sale is published at least seven days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted; (ii) Notice of the
sale describes the collateral in general, non-specific terms; (iii) The sale is
conducted at a place designated by Silicon, with or without the Collateral being
present; (iv) The sale commences at any time between 8:00 a.m. and 6:00 p.m; (v)
Payment of the purchase price in cash or by cashier's check or wire transfer is
required; (vi) With respect to any sale of any of the Collateral, Silicon may
(but is not obligated to) direct any prospective purchaser to ascertain directly
from Borrower any and all information concerning the same. Silicon shall be free
to employ other methods of noticing and selling the Collateral, in its
discretion, if they are commercially reasonable.

   7.4 POWER OF ATTORNEY. Upon the occurrence of any Event of Default, without
limiting Silicon's other rights and remedies, Borrower grants to Silicon an
irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to
Borrower, and at Borrower's expense, to do any or all of the following, in
Borrower's name or otherwise, but Silicon agrees to exercise the following
powers in a commercially reasonable manner: (a) Execute on behalf of Borrower
any documents that Silicon may, in its sole discretion, deem advisable in order
to perfect and maintain Silicon's security interest in the Collateral, or in
order to exercise a right of Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of Borrower any document
exercising, transferring or assigning any option to purchase, sell or otherwise
dispose of or to lease (as lessor or lessee) any real or personal property which
is part of Silicon's Collateral or in which Silicon has an interest; (c) Execute
on behalf of Borrower, any invoices relating to any Receivable, any draft
against any Account Debtor and any notice to any Account Debtor, any proof of
claim in bankruptcy, any Notice of Lien, claim of mechanic's, materialman's or
other lien, or assignment or satisfaction of mechanic's, materialman's or other
lien; (d) Take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into Silicon's
possession; (e) Endorse all checks and other forms of remittances received by
Silicon; (f) Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; (g)
Grant extensions of time to pay, compromise claims and settle Receivables and
General Intangibles for less than face value and execute all releases and other
documents in connection therewith; (h) Pay any sums required on account of
Borrower's taxes or to secure the release of any liens therefor, or both; (i)
Settle and adjust, and give releases of, any insurance claim that relates to any
of the Collateral and obtain payment therefor; (j) Instruct any third party
having custody or control of any books or records belonging to, or relating to,
Borrower to give Silicon the same rights of access and other rights with respect
thereto as Silicon has under this Agreement; and (k) Take any action or pay any
sum required of Borrower pursuant to this Agreement and any other present or
future agreements. Any and all reasonable sums paid and any and all reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by
Silicon with respect to the foregoing shall be added to and become part of the
Obligations, shall be payable on demand, and shall bear interest at a rate equal
to the highest interest rate applicable to any of the Obligations. In no event
shall Silicon's rights under the foregoing power of attorney or any of Silicon's
other rights under this Agreement be deemed to indicate that Silicon is in
control of the business, management or properties of Borrower.

   7.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of any sale
of the Collateral shall be applied by Silicon first to the reasonable costs,
expenses, liabilities, obligations and attorneys' fees incurred by Silicon in
the exercise of its rights under this Agreement, second to the interest due upon
any of the Obligations, and third to the principal of the Obligations, in such
order as Silicon shall determine in its sole discretion. Any surplus shall be
paid to Borrower or other persons legally entitled thereto; Borrower shall
remain liable to Silicon for any deficiency. If, Silicon, in its sole
discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Silicon shall
have the option, exercisable at any time, in its sole discretion, of either
reducing the Obligations by the principal amount of purchase price or deferring

reduction of the Obligations until the actual receipt by Silicon of the cash
therefor.

   7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set forth in
this Agreement, Silicon shall have all the other rights and remedies accorded a
secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Silicon to exercise any rights
or remedies shall not operate as a waiver thereof, but all rights and remedies
shall continue in full force and effect until all of the Obligations have been
fully paid and performed.

8. DEFINITIONS. As used in this Agreement, the following terms have the
following meanings:

   "Account Debtor" means the obligor on a Receivable.

   "Affiliate" means, with respect to any Person, a relative, partner,
shareholder, director, officer, or employee of such Person, or any parent or
subsidiary of such Person, or any Person controlling, controlled by or under
common control with such Person.

   "Business Day" means a day on which Silicon is open for business.

   "Code" means the Uniform Commercial Code as adopted and in effect in the
State of California from time to time.

   "Collateral" has the meaning set forth in Section 2.1 above.

   "Default" means any event which with notice or passage of time or both, would
constitute an Event of Default.

   "Deposit Account" has the meaning set forth in Section 9105 of the Code.

   "Eligible Foreign Inventory"  See Schedule attached hereto.

   "Eligible Foreign Receivables"  See Schedule attached hereto.

   "Eligible Inventory"  [NOT APPLICABLE].

   "Eligible Receivables" means Receivables arising in the ordinary course of
Borrower's business from the sale of goods or rendition of services, which
Silicon, in its sole judgment, shall deem eligible for borrowing, based on such
considerations as Silicon may from time to time deem appropriate. Without
limiting the fact that the determination of which Receivables are eligible for
borrowing is a matter of Silicon's discretion, the following (the "Minimum
Eligibility Requirements") are the minimum requirements for a Receivable to be
an Eligible Receivable: (i) the Receivable must not be outstanding for more than
90 days from its invoice date, (ii) the Receivable must not represent progress
billings, or be due under a fulfillment or requirements contract with the
Account Debtor, (iii) the Receivable must not be subject to any contingencies
(including Receivables arising from sales on consignment, guaranteed sale or
other terms pursuant to which payment by the Account Debtor may be conditional),
(iv) the Receivable must not be owing from an Account Debtor with whom the
Borrower has any dispute (whether or not relating to the particular Receivable),
(v) the Receivable must not be owing from an Affiliate of Borrower, (vi) the
Receivable must not be owing from an Account Debtor which is subject to any
insolvency or bankruptcy proceeding, or whose financial condition is not
acceptable to Silicon, or which, fails or goes out of a material portion of its
business, (vii) the Receivable must not be owing from the United States or any
department, agency or instrumentality thereof (unless there has been compliance,
to Silicon's satisfaction, with the United States Assignment of Claims Act),
(viii) the Receivable must not be owing from an Account Debtor located outside
the United States or Canada (unless pre-approved by Silicon in its discretion in
writing, or backed by a letter of credit satisfactory to Silicon, or FCIA
insured satisfactory to Silicon), (ix) the Receivable must not be owing from an
Account Debtor to whom Borrower is or may be liable for goods purchased from
such Account Debtor or otherwise. Receivables owing from one Account Debtor will
not be deemed Eligible Receivables to the extent they exceed 25% of the total
eligible Receivables outstanding. In addition, if more than 50% of the
Receivables owing from an Account Debtor are outstanding more than 90 days from
their invoice date (without regard to unapplied credits) or are otherwise not
eligible Receivables, then all Receivables owing from that Account Debtor will
be deemed ineligible for borrowing. Silicon may, from time to time, in its
discretion, revise the Minimum Eligibility Requirements, upon written notice to
the Borrower.

   "Equipment" means all of Borrower's present and hereafter acquired machinery,
molds, machine tools, motors, furniture, equipment, furnishings, fixtures, trade

Borrower's operations or owned by Borrower and any interest in any of the
foregoing, and all attachments, accessories, accessions, replacements,
substitutions, additions or improvements to any of the foregoing, wherever
located.

   "Event of Default" means any of the events set forth in Section 7.1 of this
Agreement.

thereby, names, trade names, trade secrets, goodwill, copyrights, registrations,
licenses, franchises, customer lists, security and other deposits, rights in all
litigation presently or hereafter pending for any cause or claim (whether in
contract, tort or otherwise), and all judgments now or hereafter arising
therefrom, all claims of Borrower against Silicon, rights to purchase or sell
real or personal property, rights as a licensor or licensee of any kind,
royalties, telephone numbers, proprietary information, purchase orders, and all
insurance policies and claims (including without limitation life insurance, key
man insurance, credit insurance, liability insurance, property insurance and
other insurance), tax refunds and claims, computer programs, discs, tapes and
tape files, claims

title and other documents representing any of the foregoing.

   "Obligations" means all present and future Loans, advances, debts,
liabilities, obligations, guaranties, covenants, duties and indebtedness at any
time owing by Borrower to Silicon, whether evidenced by this Agreement or any
note or other instrument or document, whether arising from an extension of
credit, opening of a letter of credit, banker's acceptance, loan, guaranty,
indemnification or otherwise, whether direct or indirect (including, without
limitation, those acquired by assignment and any participation by Silicon in
Borrower's debts owing to others), absolute or contingent, due or to become due,
including, without limitation, all interest, charges, expenses, fees, attorney's
fees, expert witness fees, audit fees, letter of credit fees, collateral
monitoring fees, closing fees, facility fees, termination fees, minimum interest
charges and any other sums chargeable to Borrower under this Agreement or under
any other present or future instrument or agreement between Borrower and
Silicon.

   "Permitted Liens" means the following: (i) purchase money security interests
in specific items of Equipment; (ii) leases of specific items of Equipment;
(iii) liens for taxes not yet payable; (iv) additional security interests and
liens consented to in writing by Silicon, which consent shall not be

business and securing obligations which are not delinquent; (vii) liens incurred
in connection with the extension, renewal or refinancing of the indebtedness

provided that any extension, renewal or replacement lien is limited to the
property encumbered by the existing lien and the principal amount of the
indebtedness being extended, renewed or refinanced does not increase; (viii)
Liens in favor of customs and revenue authorities which secure payment of
customs duties in connection with the importation of goods. Silicon will have
the right to require, as a condition to its consent under subparagraph (iv)
above, that the holder of the additional security interest or lien sign an
intercreditor agreement on Silicon's then standard form, acknowledge that the
security interest is subordinate to the security interest in favor of Silicon,
and agree not to take any action to enforce its subordinate security interest so
long as any Obligations remain outstanding, and that Borrower agree that any
uncured default in any obligation secured by the subordinate security interest
shall also constitute an Event of Default under this Agreement.

venture, trust, unincorporated organization, association, corporation,
government, or any agency or political division thereof, or any other entity.

   "Receivables" means all of Borrower's now owned and hereafter acquired

obligations at any time owing to Borrower, all guaranties and other security
therefor, all merchandise returned to or repossessed by Borrower, and all rights
of stoppage in transit and all other rights or remedies of an unpaid vendor,
lienor or secured party.

Loans and Letters of Credit which would otherwise be available to Borrower under
the lending formula(s) provided in the Schedule: (a) to reflect events,
conditions, contingencies or risks which, as determined by Silicon in good
faith, do or may affect either (i) the Collateral or any other property which is
security for the Obligations or its value, (ii) the assets, business or
prospects of Borrower or any Guarantor or (iii) the security interests and other

or any Guarantor to Silicon is or may have been incomplete, inaccurate or
misleading in any material respect, or (c) in respect of any state of facts
which Silicon determines in good faith constitutes an Event of Default or may,
with notice or passage of time or both, constitute an Event of Default.

   Other Terms. All accounting terms used in this Agreement, unless otherwise
indicated, shall have the meanings given to such terms in accordance with
generally accepted accounting principles, consistently applied. All other terms
contained in this Agreement, unless otherwise indicated, shall have the meanings
provided by the Code, to the extent such terms are defined therein.

9.   GENERAL PROVISIONS.

   9.1 INTEREST COMPUTATION. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Silicon (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Silicon on account of the Obligations three Business Days after
receipt by Silicon of immediately available funds, and, for purposes of the
foregoing, any such funds received after 12:00 Noon on any day shall be deemed
received on the next Business Day. Silicon shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to Silicon in its sole discretion, and Silicon may charge
Borrower's loan account for the amount of any item of payment which is returned
to Silicon unpaid.

   9.2 APPLICATION OF PAYMENTS. All payments with respect to the Obligations may
be applied, and in Silicon's sole discretion reversed and re-applied, to the



                                      -10-
<PAGE>   33
SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------


Obligations, in such order and manner as Silicon shall determine in its sole
discretion.

   9.3 CHARGES TO ACCOUNTS. Silicon may, in its discretion, require that
Borrower pay monetary Obligations in cash to Silicon, or charge them to
Borrower's Loan account, in which event they will bear interest at the same rate
applicable to the Loans. Silicon may also, in its discretion, charge any
monetary Obligations to Borrower's Deposit Accounts maintained with Silicon.

   9.4 MONTHLY ACCOUNTINGS. Silicon shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Silicon), unless Borrower
notifies Silicon in writing to the contrary within thirty days after each
account is rendered, describing the nature of any alleged errors or admissions.

   9.5 NOTICES. All notices to be given under this Agreement shall be in writing
and shall be given either personally or by reputable private delivery service or
by regular first-class mail, or certified mail return receipt requested,
addressed to Silicon or Borrower at the addresses shown in the heading to this
Agreement, or at any other address designated in writing by one party to the
other party. Notices to Silicon shall be directed to the Commercial Finance
Division, to the attention of the Division Manager or the Division Credit
Manager. All notices shall be deemed to have been given upon delivery in the
case of notices personally delivered, or at the expiration of one Business Day
following delivery to the private delivery service, or two Business Days
following the deposit thereof in the United States mail, with postage prepaid.

   9.6 SEVERABILITY. Should any provision of this Agreement be held by any court
of competent jurisdiction to be void or unenforceable, such defect shall not
affect the remainder of this Agreement, which shall continue in full force and
effect.

   9.7 INTEGRATION. This Agreement and such other written agreements, documents
and instruments as may be executed in connection herewith are the final, entire
and complete agreement between Borrower and Silicon and supersede all prior and
contemporaneous negotiations and oral representations and agreements, all of
which are merged and integrated in this Agreement. There are no oral
understandings, representations or agreements between the parties which are not
set forth in this Agreement or in other written agreements signed by the parties
in connection herewith.

   9.8 WAIVERS. The failure of Silicon at any time or times to require Borrower
to strictly comply with any of the provisions of this Agreement or any other
present or future agreement between Borrower and Silicon shall not waive or
diminish any right of Silicon later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Silicon shall be deemed to have been
waived by any act or knowledge of Silicon or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Silicon and
delivered to Borrower. Borrower waives demand, protest, notice of protest and
notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time held
by Silicon on which Borrower is or may in any way be liable, and notice of any
action taken by Silicon, unless expressly required by this Agreement.

   9.9 NO LIABILITY FOR ORDINARY NEGLIGENCE. Neither Silicon, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other party through the ordinary negligence of Silicon, or any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Silicon, but nothing herein shall relieve Silicon from
liability for its own gross negligence or willful misconduct.

   9.10 AMENDMENT. The terms and provisions of this Agreement may not be waived
or amended, except in a writing executed by Borrower and a duly authorized
officer of Silicon.

   9.11 TIME OF ESSENCE. Time is of the essence in the performance by Borrower
of each and every obligation under this Agreement.

   9.12 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following: prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement or Borrower; enforce, or seek to enforce, any of
its rights; prosecute actions against, or defend actions by, Account Debtors;
commence, intervene in, or defend any action or proceeding; initiate any
complaint to be relieved of the automatic stay in bankruptcy; file or prosecute
any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce
Silicon's security interest in, the Collateral; and otherwise represent Silicon
in any litigation relating to Borrower. In satisfying Borrower's obligation
hereunder to reimburse Silicon for attorneys fees, Borrower may, for
convenience, issue checks directly to Silicon's attorneys, Levy, Small & Lallas,
but Borrower acknowledges and agrees that Levy, Small & Lallas is representing
only Silicon and not Borrower in connection with this Agreement. If either
Silicon or Borrower files any lawsuit against the other predicated on a breach
of this Agreement, the prevailing party in such action shall be entitled to
recover its reasonable costs and attorneys' fees, including (but not limited to)
reasonable attorneys' fees and costs incurred in the enforcement of, execution
upon or defense of any order, decree, award or judgment. All attorneys' fees and
costs to which Silicon may be entitled pursuant to this Paragraph shall



                                      -11-

SILICON VALLEY BANK                                  LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------


immediately become part of Borrower's Obligations, shall be due on demand, and
shall bear interest at a rate equal to the highest interest rate applicable to
any of the Obligations.

   9.13 BENEFIT OF AGREEMENT. The provisions of this Agreement shall be binding
upon and inure to the benefit of the respective successors, assigns, heirs,
beneficiaries and representatives of Borrower and Silicon; provided, however,
that Borrower may not assign or transfer any of its rights under this Agreement
without the prior written consent of Silicon, and any prohibited assignment
shall be void. No consent by Silicon to any assignment shall release Borrower
from its liability for the Obligations.

   9.14 JOINT AND SEVERAL LIABILITY. If Borrower consists of more than one
Person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

   9.15 LIMITATION OF ACTIONS. Any claim or cause of action by Borrower against
Silicon, its directors, officers, employees, agents, accountants or attorneys,
based upon, arising from, or relating to this Loan Agreement, or any other
present or future document or agreement, or any other transaction contemplated
hereby or thereby or relating hereto or thereto, or any other matter, cause or
thing whatsoever, occurred, done, omitted or suffered to be done by Silicon, its
directors, officers, employees, agents, accountants or attorneys, shall be
barred unless asserted by Borrower by the commencement of an action or
proceeding in a court of competent jurisdiction by the filing of a complaint
within one year after the first act, occurrence or omission upon which such
claim or cause of action, or any part thereof, is based, and the service of a
summons and complaint on an officer of Silicon, or on any other person
authorized to accept service on behalf of Silicon, within thirty (30) days
thereafter. Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Silicon in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

   9.16 PARAGRAPH HEADINGS; CONSTRUCTION. Paragraph headings are only used in
this Agreement for convenience. Borrower and Silicon acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,
define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Silicon or Borrower under any rule
of construction or otherwise.

   9.17 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and Borrower
shall be governed by the laws of the State of California. As a material part of
the consideration to Silicon to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Silicon's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Santa Clara County;
(ii) consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or any
other method permitted by law; and (iii) waives any and all rights Borrower may
have to object to the jurisdiction of any such court, or to transfer or change
the venue of any such action or proceeding.

   9.18 MUTUAL WAIVER OF JURY TRIAL. BORROWER AND SILICON EACH HEREBY WAIVE THE
RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT OF,
OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE
INSTRUMENT OR AGREEMENT BETWEEN SILICON AND BORROWER, OR ANY CONDUCT, ACTS OR
OMISSIONS OF SILICON OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SILICON OR BORROWER, IN

                                        time to time, the "Silicon Agreement").
                                        This Agreement and the Silicon Agreement
                                        shall continue in full force and effect,

2.  INTEREST.

         INTEREST RATE (Section 1.2):

                                        A rate equal to the "Prime Rate" in
                                        effect from time to time, plus 1.0% per
                                        annum. Interest shall be calculated on
                                        the basis of a 360-day year for the
                                        actual number of days elapsed. "Prime
                                        Rate" means the rate announced from time
                                        to time by Silicon as its "prime rate;"
                                        it is a base rate upon which other rates
                                        charged by Silicon are based, and it is
                                        not necessarily the best rate available
                                        at Silicon. The interest rate applicable
                                        to the Obligations shall change on each
                                        date there is a change in the Prime
                                        Rate.
