Borrower (the "Loans") in amounts determined by Silicon in its reasonable

Loans and other Obligations outstanding from time to time, and Borrower shall
not permit the same, at any time, to exceed the Credit Limit.  If at any time
the total of all outstanding Loans and all other Obligations exceeds the Credit

without notice or demand.

 1.2  INTEREST.  All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule hereto.  Interest shall be payable

Borrower.  Silicon may, in its discretion, charge interest to Borrower's
deposit accounts maintained with Silicon.

 1.3  FEES.  The Borrower shall pay to Silicon a loan origination fee in the

discretion.

3.    REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

 The Borrower represents and warrants to Silicon as follows, and the Borrower
covenants that the following representations will continue to be true, and that
the Borrower will comply with all of the following covenants:

 3.1  CORPORATE EXISTENCE AND AUTHORITY.  The Borrower, if a corporation, is
and will continue to be, duly authorized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation.  The 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 the
Borrower.  The execution, delivery and performance by the Borrower of this
Agreement, and all other documents contemplated hereby have been duly and
validly authorized, are enforceable against the Borrower in accordance with
their terms, and do not violate any law or any provision of, and are not
grounds for acceleration under, any agreement or instrument which is binding
upon the Borrower.

 3.2  NAME; TRADE NAMES AND STYLES.  The name of the Borrower set forth in the
heading to this Agreement is its correct name.  Listed on the Schedule hereto
are all prior names of the Borrower and all of Borrower's present and prior
trade names.  The Borrower shall give Silicon 15 days' prior written notice
before changing its name or doing business under any other name.  The 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 the Borrower's chief executive office.  In
addition, the Borrower has places of business and Collateral is located only at
the locations set forth on the Schedule to this Agreement.  The Borrower will
give Silicon at least 15 days prior written notice before changing its chief
executive office or locating the Collateral at any other location.

 3.4  TITLE TO COLLATERAL; PERMITTED LIENS.  The 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 the 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 the following ("Permitted Liens"):
(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
in its reasonable discretion, which consent shall not be unreasonably withheld;
and (v) security interests being terminated substantially concurrently with
this Agreement.  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 the 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.  Silicon now has, and will continue
to have, a perfected and enforceable security interest in all of the
Collateral, subject only to the Permitted Liens, and the 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.

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

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

 3.7  FINANCIAL CONDITION AND STATEMENTS.  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 the Borrower, at
the times and for the periods therein stated.  Since the last date covered by
any such statement, there has been no material adverse change in the


                                     -2-

financial condition or business of the Borrower.  The Borrower is now and will
continue to be solvent.  The Borrower will provide Silicon:  (i) within 30 days
after the end of each month, a monthly financial statement prepared by the
Borrower, and a Compliance Certificate in such form as Silicon shall reasonably
specify, signed by the Chief Financial Officer of the Borrower, certifying that
as of the end of such month the Borrower was in full compliance with all of the
terms and conditions of this Agreement, and setting forth calculations showing
compliance with the financial covenants set forth on the Schedule and such
other information as Silicon shall reasonably request; and (ii) * [and (ii)
within 120 days following the end of the Borrower's fiscal year, complete

IS REQUIRED TO BE FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, SUCH 10-Q
REPORT, A QUARTERLY FINANCIAL STATEMENT PREPARED BY THE BORROWER, AND A

IS REQUIRED TO BE FILED WITH THE SECURITIES AND EXCHANGE COMMISSION, SUCH 10-K
REPORT, COMPLETE ANNUAL FINANCIAL STATEMENTS, CERTIFIED BY INDEPENDENT
CERTIFIED PUBLIC ACCOUNTANTS ACCEPTABLE TO SILICON, AND A COMPLIANCE

THE BORROWER, CERTIFYING THAT THROUGHOUT SUCH PERIOD THE BORROWER WAS IN FULL
COMPLIANCE WITH ALL OF THE TERMS AND CONDITIONS OF THIS AGREEMENT, AND SETTING
FORTH CALCULATIONS SHOWING COMPLIANCE WITH THE FINANCIAL COVENANTS SET FORTH ON
THE SCHEDULE AND SUCH OTHER INFORMATION AS SILICON SHALL REASONABLY REQUEST.

filed, and will timely file, all tax returns and reports required by foreign,
federal, state and local law, and the 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 the Borrower.  The Borrower may,
however, defer payment of any contested taxes, provided that the Borrower (i)
in good faith contests the 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.  The Borrower is unaware of any claims or adjustments proposed for
any of the Borrower's prior tax years which could result in additional taxes
becoming due and payable by the Borrower.  The 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 the 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 the
Borrower, including, without limitation, any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.

 3.9  COMPLIANCE WITH LAW.  The 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 the Borrower, including, but not limited to,
those relating to the Borrower's ownership of real or personal property,
conduct and licensing of the Borrower's business, and 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 the
Borrower's knowledge) threatened by or against or affecting the Borrower in any
court or before any governmental agency (or any basis therefor known to the
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of the Borrower,
or in any material impairment in the ability of the Borrower to carry on its
business in substantially the same manner as it is now being conducted.  The
Borrower will promptly inform Silicon in writing of any claim, proceeding,
litigation or investigation in the future threatened or instituted by or
against the Borrower involving amounts in excess of $250,000.

 4.2  OVERADVANCE; PROCEEDS OF ACCOUNTS.  If for any reason the total of all
outstanding Loans and all other Obligations exceeds the Credit Limit, without
limiting Silicon's other remedies, and whether or not Silicon declares an Event

Borrower's accounts and general intangibles, in the same form as received by
Borrower, within one day after Borrower's receipt of the same, to be applied to
the Obligations in such order as Silicon shall determine in its discretion.

reduction of the Obligations as Silicon shall determine in its sole and
absolute discretion, except that, provided no Event of Default has occurred,
Silicon shall release to the Borrower insurance proceeds with respect to
equipment totaling less than $100,000, which shall be utilized by the Borrower
for the replacement of the equipment with respect to which the insurance
proceeds were paid.  Silicon may require reasonable assurance that the

accounts receivable audits by third parties retained by Silicon, and Silicon
may debit Borrower's deposit accounts with Silicon for the cost of such
semi-annual accounts receivable audits (in which event Silicon shall send
notification thereof to the Borrower) **.  Notwithstanding the foregoing, after
the occurrence of an Event of Default all audits shall be at the Borrower's
expense.

notification to Borrower, verify directly with the respective account debtors
the validity, amount and other matters relating to the Borrower's accounts, by

Silicon or such other name as Silicon may reasonably choose, provided that no
prior notification to Borrower shall be required following an Event of Default.

 4.9  EXECUTE ADDITIONAL DOCUMENTATION.  The Borrower agrees, at its expense,
on request by Silicon, to execute all documents in form satisfactory to
Silicon, as Silicon, may deem reasonably necessary or useful in order to

5.    TERM.

 5.1  MATURITY DATE.  This Agreement shall continue in effect until the
maturity date set forth on the Schedule hereto (the "Maturity Date").

 5.2  EARLY TERMINATION.  This Agreement may be terminated, without penalty,
prior to the Maturity Date as follows: (i) by the 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.

 5.3  PAYMENT OF OBLIGATIONS.  On the Maturity Date or on any earlier effective
date of termination, the 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 reasonable 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 the 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, Silicon shall promptly deliver to
the Borrower termination statements, requests for reconveyances and such other
documents as may be required to fully terminate any of Silicon's security
interests.

other monetary Obligation; or (c) the total Loans and other Obligations

of proceedings by or against any such third party under any bankruptcy or
insolvency law; or (k) the Borrower makes any payment on account of any
indebtedness or obligation which has been subordinated to the Obligations other

who has subordinated such indebtedness or obligations terminates or in any way
limits his subordination agreement; or (l) 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 the Borrower, in one or more transactions,
compared to the ownership of outstanding shares of stock of the Borrower in
effect on the date hereof, without the prior written consent of Silicon; or (m)
the Borrower shall generally not pay its debts as they become due; or the
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 which may be fraudulent under any bankruptcy,
fraudulent conveyance or similar law.  Silicon may cease making any Loans
hereunder during any of the above cure periods, and thereafter if an Event of
Default has occurred.

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 or all of the Collateral by Court process, the 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

repair, at any one or more public and/or private sales, in lots or in bulk, for
cash, exchange or other property, or on credit, and to 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 the 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 the
Borrower of any liability the Borrower may have if any Collateral is defective
as to title or physical condition or otherwise at the time of sale; (h) Demand
payment of, and collect any accounts and general intangibles comprising
Collateral and, in connection therewith, the Borrower irrevocably authorizes
Silicon to endorse or sign the Borrower's name on all collections, receipts,
instruments and other documents, to take possession of and open mail addressed
to the 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 accounts and the like
for less than face value; (i) Offset against any sums in any of Borrower's
general, special or other deposit accounts with Silicon; and (j) Demand and
receive possession of any of the 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.

 6.3  STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS.  The 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 the
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 the Borrower any
and all information concerning the same.  Silicon may employ other methods of
noticing and selling the Collateral, in its discretion, if they are
commercially reasonable.

 6.4  POWER OF ATTORNEY.  Upon the occurrence of any Event of Default, without
limiting Silicon's other rights and remedies, the 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
the Borrower, and at the Borrower's expense, to do any or all of the following,
in the Borrower's name or otherwise: (a) Execute on behalf of the Borrower any
documents that Silicon may, in its sole and absolute discretion, deem advisable
in order to perfect and maintain Silicon's security

interest in the Collateral, or in order to exercise a right of the 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 the 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 the Borrower, any
invoices relating to any account, 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 the 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 accounts 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 the 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, the 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 the Borrower pursuant to this Agreement and any other present or
future agreements.  Silicon shall exercise the foregoing powers in a
commercially reasonable manner.  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 the
Borrower.

 6.5  APPLICATION OF PROCEEDS.  All proceeds realized as the result of any sale
of the Collateral shall be applied by Silicon first to the 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 the Borrower or other persons legally entitled thereto; the 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 or other disposition 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.

 6.6  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 the 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.

7.    GENERAL PROVISIONS.

 7.1  NOTICES.  All notices to be given under this Agreement shall be in
writing and shall be given either personally or by regular first-class mail, or
certified mail return receipt requested, addressed to Silicon or the 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.  All notices
shall be deemed to have been given upon delivery in the case of notices
personally delivered to the Borrower or to Silicon, or at the expiration of two
business days following the deposit thereof in the United States mail, with
postage prepaid.

 7.2  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.

 7.3  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 the 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.

 7.4  WAIVERS.  The failure of Silicon at any time or times to require the
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future





                                     -7-
   8

SILICON VALLEY BANK                                LOAN AND SECURITY AGREEMENT


agreement between the 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 thereto.  None of the provisions of this Agreement or any
other agreement now or in the future executed by the 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
officer of Silicon and delivered to the Borrower.  The 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 the Borrower is or may in any way be
liable, and notice of any action taken by Silicon, unless expressly required by
this Agreement.

 7.5  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 the 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.

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

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

 7.8  ATTORNEYS FEES AND COSTS.  The 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; 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 the 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 the 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 the 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 immediately become part of the 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.

 7.9  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 the parties hereto; provided, however,
that the 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 the Borrower from its liability for the Obligations.

 7.10  JOINT AND SEVERAL LIABILITY.  If the 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.

 7.11  PARAGRAPH HEADINGS; CONSTRUCTION.  Paragraph headings are only used in
this Agreement for convenience.  The Borrower acknowledges 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.  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 the Borrower under any rule of construction or
otherwise.

 7.12 MUTUAL WAIVER OF JURY TRIAL.  THE 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 THE BORROWER, OR ANY CONDUCT, ACTS
OR OMISSIONS OF SILICON OR THE BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SILICON OR
THE BORROWER, IN ALL OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR
TORT OR OTHERWISE.

 7.13  GOVERNING LAW; JURISDICTION; VENUE.  This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and the
Borrower shall be governed by, and in accordance with, the laws of the State of
California.  Any undefined term used in this Agreement that is defined in the
California Uniform Commercial Code shall have the meaning assigned to that term
in the California Uniform Commercial Code.  As a material part of the
consideration to Silicon to enter into this Agreement, the Borrower (i) agrees
that all actions and proceedings relating directly or indirectly hereto shall,
at Silicon's option, be litigated in courts located within California, and that
the exclusive venue therefor shall be Orange 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 the 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.

         THIS SCHEDULE is an integral part of the Loan and Security Agreement
between Silicon Valley Bank ("Silicon") and the above-named borrower
("Borrower") of even date.

CREDIT LIMIT
(Section 1.1):                        An amount not to exceed the lesser of:
                                      (i) $2,000,000 at any one time
                                      outstanding; or (ii) 70% of the Net
                                      Amount of Borrower's accounts, which
                                      Silicon in its discretion deems eligible
                                      for borrowing*.  "Net Amount" of an
                                      account means the gross amount of the
                                      account, minus all applicable sales, use,
                                      excise and other similar taxes and minus
                                      all discounts, credits and allowances of
                                      any nature granted or claimed.

                                      SCHEDULE ENTITLED "OTHER COVENANTS
                                      (SECTION 4.1)".

                                      Without limiting the fact that the
                                      determination of which accounts are
                                      eligible for borrowing is a matter of
                                      Silicon's discretion, the following will
                                      not be deemed eligible for borrowing*:
                                      accounts outstanding for more than 90
                                      days from the invoice date, accounts
                                      subject to any contingencies, accounts
                                      owing from the United States or any
                                      department, agency or instrumentality of
                                      the United States or any state, city or
                                      municipality**, accounts owing from an
                                      account debtor outside the United States
                                      *** (unless pre-approved by Silicon in
                                      its discretion, or backed by a letter of
                                      credit satisfactory to Silicon, or FCIA
                                      insured satisfactory to Silicon),
                                      accounts owing from one account debtor to
                                      the extent they exceed 25% of the total
                                      eligible accounts outstanding, accounts
                                      owing from an affiliate of Borrower, and
                                      accounts owing from an account debtor to
                                      whom Borrower is or may be liable for
                                      goods purchased from such account debtor
                                      or otherwise.  In addition, if more than
                                      50% of the accounts owing from an account
                                      debtor are outstanding more than 90 days
                                      from the invoice date or are otherwise
                                      not eligible accounts, then all accounts
                                      owing from that account debtor will be
                                      deemed ineligible for borrowing.

                                      equal to the face amount of all such
                                      letters of credit plus all interest, fees
                                      and cost due or to become due in

                                      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

                                      terminates the Exchange Contracts, and
                                      without limitation of the FX Indemnity
                                      Provisions (as referred to below),
                                      Borrower agrees to reimburse Silicon for

                                      therewith.

                                      Borrower shall not permit the total gross
                                      amount of all Exchange Contracts on which

                                      outstanding at any one time, to exceed
                                      the Contract Limit.

                                      Notwithstanding the above, however, the
                                      amount which may be settled in any two
                                      (2) business day period may, in Silicon's

                                      circumstances (the "Discretionary
                                      Settlement Circumstances"):

                                        (i) if there is sufficient availability
                                        under the Credit Limit in the amount
                                        of the Foreign Exchange Reserve as
                                        of each Determination Date, provided
                                        that Silicon in advance shall reserve
                                        the full 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)
                                        business day period if Silicon 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 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 in advance
                                      shall instruct Silicon 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

                                      accepted accounting principles, excluding
                                      however all assets which would be
                                      classified as intangible assets under
                                      generally accepted accounting principles,

                                      purposes of such ratio.  For all other
                                      purposes deferred revenues shall be
                                      counted as liabilities in accordance with
                                      generally accepted accounting principles.
