     The parties agree as follows:

1    ACCOUNTING AND OTHER TERMS
     --------------------------

     Accounting terms not defined in this Agreement will be construed following
GAAP Calculations and determinations must be made following GAAP. The term
"financial statements" includes the notes and schedules. The terms "including"
and "includes" always mean "including (or includes) without limitation," in this
or any Loan Document. This Agreement shall be construed to impart upon Bank a
duty to act reasonably at all times.

2    LOAN AND TERMS OF PAYMENT
     -------------------------

2.1  Credit Extensions.

     Borrower will pay Bank the unpaid principal amount of all Credit Extensions
and interest on the unpaid principal amount of the Credit Extensions.

2.1.1  Revolving Advances.

     (a) Bank will make Advances not exceeding (i) the lesser of (A) the

repaid and reborrowed during the term of this Agreement.

     (b) To obtain an Advance, Borrower must notify Bank by facsimile or

2.1.2  Letters of Credit.

     Bank will issue or have issued Letters of Credit for Borrower's account not

Letters of Credit and any Letter of Credit Reserve) may not exceed $250,000.
Each Letter of Credit will have an expiry date of no later than 180 days after

and installation expense. Software may constitute up to 25% of the aggregate
Equipment Advances. Each Equipment Advance must be for a minimum of $10,000.

     (b) Interest continues to accrue from the date of each Equipment Advance at
the rate in Section 2.3(a) and is payable monthly until the Equipment
Availability End Date occurs. Equipment Advances outstanding on the Equipment
Availability End Date are payable in 36 equal monthly installments of principal,
plus accrued interest, beginning on the 27th of each month following the
Equipment Availability End Date and ending on July 27, 2002 (the "Equipment
Maturity Date"). Equipment Advances when repaid may not be reborrowed.

     (c) To obtain an Equipment Advance, Borrower must notify Bank (the notice
is irrevocable) by facsimile no later than 3:00 p.m. Pacific time 1 Business Day

     If Borrower's Obligations under Section 2.1.1 and 2.1.2 exceed the lesser
of either (i) the Committed Revolving Line or (ii) the Borrowing Base, Borrower
must immediately pay Bank the excess.

2.3  Interest Rate, Payments.

     (a) Interest Rate. (i) Advances accrue interest on the outstanding
principal balance at a per annum rate of 0.75 percentage point above the Prime
Rate; and (ii) Equipment Advances accrue interest on the outstanding principal
balance at a per annum rate of 1 percentage point above the Prime Rate. After an
Event of Default, Obligations accrue interest at 5 percent above the rate
effective immediately before the Event of Default. The interest rate increases
or decreases when the Prime Rate changes. Interest is computed on a 360 day year
for the actual number of days elapsed.

     (b) Payments. Interest due on the Committed Revolving Line is payable on
the 18th of each month. Interest due on the Equipment Advances is payable on the
27th of each month. Bank may debit any of Borrower's deposit accounts including
Account Number 273056170 for principal and interest payments or any amounts

accounts. These debits are not a set-off. Payments received after 12:00 noon
Pacific time are considered received at the opening of business on the next
Business Day. When a payment is due on a day that is not a Business Day, the
payment is due the next Business Day and additional fees or interest accrue.

occurs, or if the default cannot be cured within 10 days or cannot be cured
after Borrower's attempts within 10 day period, and the default may be cured
within a reasonable time, then Borrower has an additional period (of not more
than 30 days) to attempt to cure the default. During the additional time, the
failure to cure the default is not an Event of Default (but no Credit Extensions
will be made during the cure period);

8.3  Material Adverse Change.

     (i) If there occurs a material impairment in the perfection or priority of
the Bank's security interest in the Collateral or in the value of such
Collateral which is not covered by adequate insurance or (ii) if the Bank

seizure or levy is not removed in 10 days, or if Borrower is enjoined,
restrained, or prevented by court order from conducting a material part of its
business or if a judgment or other claim becomes a Lien on a material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed against
any of Borrower's assets by any government agency and not paid within 10 days
after Borrower receives notice. These are not Events of Default if stayed or if
a bond is posted pending contest by Borrower (but no Credit Extensions will be
made during the cure period);

8.5  Insolvency.

     If Borrower becomes insolvent or if Borrower begins an Insolvency
Proceeding or an Insolvency Proceeding is begun against Borrower and not
dismissed or stayed within 30 days (but no Credit Extensions will be made before
any Insolvency Proceeding is dismissed);

8.6  Other Agreements.

representation in this Agreement or in any writing delivered to Bank or to

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

9.1  Rights and Remedies.

     When an Event of Default occurs and continues Bank may, without notice or
demand, do any or all of the following:

     (a) Declare all Obligations immediately due and payable (but if an Event of
Default described in Section 8.5 occurs all Obligations are immediately due and
payable without any action by Bank);

     (b) Stop advancing money or extending credit for Borrower's benefit under
this Agreement or under any other agreement between Borrower and Bank;

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

     (d) Make any payments and do any acts it considers necessary or reasonable
to protect its security interest in the Collateral. Borrower will assemble the
Collateral if Bank requires and make it available as Bank designates. Bank may
enter premises where the Collateral is located, take and maintain possession of
any part of the Collateral, and pay, purchase, contest, or compromise any Lien
which appears to be prior or superior to its security interest and pay all
expenses incurred. Borrower grants Bank a license to enter and occupy any of its
premises, without charge, to exercise any of Bank's rights or remedies;

     (e) Apply to the Obligations any (i) balances and deposits of Borrower it
holds, or (ii) any amount held by Bank owing to or for the credit or the account
of Borrower;

     (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell the Collateral; and

     (g) Dispose of the Collateral according to the Code.

9.2  Power of Attorney.

     Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to: (i) endorse Borrower's name
on any checks or other forms of payment or security; (ii) sign Borrower's name
on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits. Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has

                                       12
<PAGE>

occurred. Bank's appointment as Borrower's attorney in fact, and all of Bank's
rights and powers, coupled with an interest, are irrevocable until all
Obligations have been fully repaid and performed and Bank's obligation to
provide Credit Extensions terminates.

9.3  Accounts Collection.

     When an Event of Default occurs and continues, Bank may notify any Person
owing Borrower money of Bank's security interest in the funds and verify the
amount of the Account. Borrower must collect all payments in trust for Bank and,
if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.

9.4  Bank Expenses.

     If Borrower fails to pay any amount or furnish any required proof of
payment to third persons Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent. Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral. No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5  Bank's Liability for Collateral.

     If Bank complies with reasonable banking practices it is not liable for:
(a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral;
(c) any diminution in the value of the Collateral; or (d) any act or default of
any carrier, warehouseman, bailee, or other person. Borrower bears all risk of
loss, damage or destruction of the Collateral.

9.6  Remedies Cumulative.

     Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative. Bank has all rights and remedies provided
under the Code, by law, or in equity. Bank's exercise of one right or remedy is
not an election, and Bank's waiver of any Event of Default is not a continuing
waiver. Bank's delay is not a waiver, election, or acquiescence. No waiver is
effective unless signed by Bank and then is only effective for the specific
instance and purpose for which it was given.

9.7  Demand Waiver.

     Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

OBLIGATIONS OF GRANTOR. Grantor warrants and covenants to Lender as follows:

  Perfection of Security Interest. Grantor agrees to execute such financing
  statements and to take whatever other actions are requested by Lender to
  perfect and continue Lender's security interest in the Collateral. Upon
  request of Lender, Grantor will deliver to Lender any and all of the documents
  evidencing or constituting the Collateral, and Grantor will note Lender's
  interest upon any and all chattel paper if not delivered to Lender for
  possession by Lender. Grantor hereby appoints Lender as its irrevocable
  attorney-in-fact for the purpose of executing any documents necessary to
  perfect or to continue the security interest granted in this Agreement. Lender
  may at any time, and without further authorization from Grantor, file a
  carbon, photographic or other reproduction of any financing statement or of
  this Agreement for use as a financing statement. Grantor will reimburse Lender
  for all expenses for the perfection and the continuation of the perfection of
  Lender's security interest in the Collateral. Grantor promptly will notify
  Lender before any change in Grantor's name including any change to the assumed
  business names of Grantor. This is a continuing Security Agreement and will
  continue in effect even though all or any part of the Indebtedness is paid in
  full and even though for a period of time Grantor may not be indebted to
  Lender.

  No Violation. The execution and delivery of this Agreement will not violate
  any law or agreement governing Grantor or to which Grantor is a party, and its
  certificate or articles of incorporation and bylaws do not prohibit any term
  or condition of this Agreement.

  Enforceability of Collateral. To the extent the Collateral consists of
  accounts, contract fights, chattel paper, or general intangibles, the
  Collateral is enforceable in accordance with its terms, is genuine, and
  complies with applicable laws concerning form, content and manner of
  preparation and execution, and all persons appearing to be obligated on the
  Collateral have authority and capacity to contract and are in fact obligated
  as they appear to be on the Collateral.

  Location of the Collateral. Grantor, upon request of Lender, will deliver to
  Lender in form satisfactory to Lender a schedule of real properties and
  Collateral locations relating to Grantor's operations, including without
  limitation the following: (a) all real property owned or being purchased

                         COMMERCIAL SECURITY AGREEMENT
                                  (Continued)
================================================================================

by Grantor; (b) all real property being rented or leased by Grantor; (c) all
storage facilities owned, rented, leased, or being used by Grantor; and (d) all
other properties where Collateral is or may be located. Except in the ordinary
course of its business, Grantor shall not remove the Collateral from its
existing locations without the prior written consent of Lender.

Removal of Collateral. Grantor shall keep the Collateral (or to the extent the
Collateral consists of intangible property such as accounts, the records
concerning the Collateral) at Grantor's address shown above, or at such other
locations as are acceptable to Lender. Except in the ordinary course of its
business, including the sales of inventory, Grantor shall not remove the
Collateral from its existing locations without the prior written consent of
Lender. To the extent that the Collateral consists of vehicles, or other titled
property, Grantor shall not take or permit any action which would require
application for certificates of title for the vehicles outside the State of
California, without the prior written consent of Lender.

Transactions Involving Collateral. Except for inventory sold or accounts
collected in the ordinary course of Grantor's business, Grantor shall not sell,
offer to sell, or otherwise transfer or dispose of the Collateral. While Grantor
is not in default under this Agreement, Grantor may sell inventory, but only in
the ordinary course of its business and only to buyers who qualify as a buyer in
the ordinary course of business. A sale in the ordinary course of Grantor's
business does not include a transfer in partial or total satisfaction of a debt
or any bulk sale. Grantor shall not pledge, mortgage, encumber or otherwise
permit the Collateral to be subject to any lien, security interest, encumbrance,
or charge, other than the security interest provided for in this Agreement,
without the prior written consent of Lender. This includes security interests
even if junior in right to the security interests granted under this Agreement.
Unless waived by Lender, all proceeds from any disposition of the Collateral
(for whatever reason) shall be held in trust for Lender and shall not be
commingled with any other funds; provided however, this requirement shall not
constitute consent by Lender to any sale or other disposition. Upon receipt,
Grantor shall immediately deliver any such proceeds to Lender.

Title. Grantor represents and warrants to Lender that it holds good and
marketable title to the Collateral, free and clear of all liens and encumbrances
except for the lien of this Agreement. No financing statement covering any of
the Collateral is on file in any public office other than those which reflect
the security interest created by this Agreement or to which Lender has
specifically consented. Grantor shall defend Lender's rights in the Collateral
against the claims and demands of all other persons.

Collateral Schedules and Locations. Insofar as the Collateral consists of
inventory, Grantor shall deliver to Lender, as often as Lender shall require,
such lists, descriptions, and designations of such Collateral as Lender may
require to identify the nature, extent, and location of such Collateral. Such
information shall be submitted for Grantor and each of its subsidiaries or
related companies.

Maintenance and Inspection of Collateral. Grantor shall maintain all tangible
Collateral in good condition and repair. Grantor will not commit or permit
damage to or destruction of the Collateral or any part of the Collateral. Lender
and its designated representatives and agents shall have the right at all
reasonable times to examine, inspect, and audit the Collateral wherever located.
Grantor shall immediately notify Lender of all cases involving the return,
rejection, repossession, loss or damage of or to any Collateral; of any request
for credit or adjustment or of any other dispute arising with respect to the
Collateral; and generally of all happenings and events affecting the Collateral
or the value or the amount of the Collateral.

Taxes, Assessments and Liens. Grantor will pay when due all taxes, assessments
and liens upon the Collateral, its use or operation, upon this Agreement, upon
any promissory note or notes evidencing the Indebtedness, or upon any of the
other Related Documents. Grantor may withhold any such payment or may elect to
contest any lien if Grantor is in good faith conducting an appropriate
proceeding to contest the obligation to pay and so long as Lender's interest in
the Collateral is not jeopardized in Lender's sole opinion. If the Collateral is
subjected to a lien which is not discharged within fifteen (15) days, Grantor
shall deposit with Lender cash, a sufficient corporate surety bond or other
security satisfactory to Lender in an amount adequate to provide for the
discharge of the lien plus any interest, costs, attorneys' fees or other charges
that could accrue as a result of foreclosure or sale of the Collateral. In any
contest Grantor shall defend itself and Lender and shall satisfy any final
adverse judgment before enforcement against the Collateral. Grantor shall name
Lender as an additional obligee under any surety bond furnished in the contest
proceedings.

Compliance With Governmental Requirements. Grantor shall comply promptly with
all laws, ordinances, rules and regulations of all governmental authorities, now
or hereafter in effect, applicable to the ownership, production, disposition, or
use of the Collateral. Grantor may contest in good faith any such law, ordinance
or regulation and withhold compliance during any proceeding, including
appropriate appeals, so long as Lender's interest in the Collateral, in Lender's
opinion, is not jeopardized.

Hazardous Substances. Grantor represents and warrants that the Collateral never
has been, and never will be so long as this Agreement remains a lien on the
Collateral, used for the generation, manufacture, storage, transportation,
treatment, disposal, release or threatened release of any hazardous waste or
substance, as those terms are defined in the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C. Section
9601, et seq. ("CERCLA"), the Superfund Amendments and Reauthorization Act of
1986, Pub. L. No. 99-499 ("SARA"), the Hazardous Materials Transportation Act,
49 U.S.C. Section 1801, et seq., the Resource Conservation and Recovery Act, 49
U.S.C. Section 6901, et seq., Chapters 6.5 through 7.7 of Division 20 of the
California Health and Safety Code, Section 25100, et seq., or other applicable
state or Federal laws, rules, or regulations adopted pursuant to any of the
foregoing. The terms "hazardous waste" and "hazardous substance" shall also
include, without limitation, petroleum and petroleum by-products or any fraction
thereof and asbestos. The representations and warranties contained herein are
based on Grantor's due diligence in investigating the Collateral for hazardous
wastes and substances. Grantor hereby (a) releases and waives any future claims
against Lender for indemnity or contribution in the event Grantor becomes liable
for cleanup or other costs under any such laws, and (b) agrees to indemnify and
hold harmless Lender against any and all claims and losses resulting from a
breach of this provision of this Agreement. This obligation to indemnify shall
survive the payment of the Indebtedness and the satisfaction of this Agreement.

Maintenance of Casualty Insurance. Grantor shall procure and maintain all risks
insurance, including without limitation fire, theft and liability coverage
together with such other insurance as Lender may require with respect to the
Collateral, in form, amounts, coverages and basis reasonably acceptable to
Lender and issued by a company or companies reasonably acceptable to Lender.
Grantor, upon request of Lender, will deliver to Lender from time to time the
policies or certificates of insurance in form satisfactory to Lender, including
stipulations that coverages will not be cancelled or diminished without at least
ten (10) days' prior written notice to Lender and not including any disclaimer
of the insurer's liability for failure to give such a notice. Each insurance
policy also shall include an endorsement providing that coverage in favor of
Lender will not be impaired in any way by any act, omission or default of
Grantor or any other person. In connection with all policies covering assets in
which Lender holds or is offered a security interest, Grantor will provide
Lender with such loss payable or other endorsements as Lender may require. If
Grantor at any time fails to obtain or maintain any insurance as required under
this Agreement, Lender may (but shall not be obligated to) obtain such insurance
as Lender deems appropriate, including if it so chooses "single interest
insurance," which will cover only Lender's interest in the Collateral.

Application of Insurance Proceeds. Grantor shall promptly notify Lender of any
loss or damage to the Collateral. Lender may make proof of loss if Grantor fails
to do so within fifteen (15) days of the casualty. All proceeds of any insurance
on the Collateral, including accrued proceeds thereon, shall be held by Lender
as part of the Collateral. If Lender consents to repair or replacement of the
damaged or destroyed Collateral, Lender shall, upon satisfactory proof of
expenditure, pay or reimburse Grantor from the proceeds for the reasonable cost
of repair or restoration. If Lender does not consent to repair or replacement of
the Collateral, Lender shall retain a sufficient amount of the proceeds to pay
all of the Indebtedness, and shall pay the balance to Grantor. Any proceeds
which have not been disbursed within six (6) months after their receipt and

================================================================================

  which Grantor has not committed to the repair or restoration of the Collateral
  shall be used to repay the Indebtedness.

  Insurance Reserves. Lender may require Grantor to maintain with Lender
  reserves for payment of insurance premiums, which reserves shall be created by
  monthly payments from Grantor of a sum estimated by Lender to be sufficient to
  produce, at least fifteen (15) days before the premium due date, amounts at
  least equal to the insurance premiums to be paid. If fifteen (15) days before
  payment is due, the reserve funds are Insufficient, Grantor shall upon demand
  pay any deficiency to Lender. The reserve funds shall be held by Lender as a
  general deposit and shall constitute a non-interest-bearing account which
  Lender may satisfy by payment of the insurance premiums required to be paid by
  Grantor as they become due. Lender does not hold the reserve funds in trust
  for Grantor, and Lender is not the agent of Grantor for payment of the
  insurance premiums required to be paid by Grantor. The responsibility for the
  payment of premiums shall remain Grantor's sole responsibility.

  Insurance Reports. Grantor, upon request of Lender, shall furnish to Lender
  reports on each existing policy of insurance showing such information as
  Lender may reasonably request including the following: (a) the name of the
  insurer; (b) the risks insured; (c) the amount of the policy; (d) the property
  insured; (e) the then current value on the basis of which insurance has been
  obtained and the manner of determining that value; and (f) the expiration date
  of the policy. In addition, Grantor shall upon request by Lender (however not
  more often than annually) have an independent appraiser satisfactory to Lender
  determine, as applicable, the cash value or replacement cost of the
  Collateral.

GRANTOR'S RIGHT TO POSSESSION. Until default, Grantor may have possession of the
tangible personal property and beneficial use of all the Collateral and may use
it in any lawful manner not inconsistent with this Agreement or the Related
Documents, provided that Grantor's right to possession and beneficial use shall
not apply to any Collateral where possession of the Collateral by Lender is
required by law to perfect Lender's security interest in such Collateral. If
Lender at any time has possession of any Collateral, whether before or after an
Event of Default, Lender shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral if Lender takes such action for
that purpose as Grantor shall request or as Lender, in Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any request
by Grantor shall not of itself be deemed to be a failure to exercise reasonable
care. Lender shall not be required to take any steps necessary to preserve any
rights in the Collateral against prior parties, nor to protect, preserve or
maintain any security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER. If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without limitation
all taxes, liens, security interests, encumbrances, and other claims, at any
time levied or placed on the Collateral. Lender also may (but shall not be
obligated to) pay all costs for insuring, maintaining and preserving the
Collateral. All such expenditures incurred or paid by Lender for such purposes
will then bear interest at the rate charged under the Note from the date
incurred or paid by Lender to the date of repayment by Grantor. All such
expenses shall become a part of the Indebtedness and, at Lender's option, will
(a) be payable on demand, (b) be added to the balance of the Note and be
apportioned among and be payable with any installment payments to become due
during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will be
due and payable at the Note's maturity. This Agreement also will secure payment
of these amounts. Such right shall be in addition to all other rights and
remedies to which Lender may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT. Each of the following shall constitute an Event of Default
under this Agreement:

  Default on Indebtedness. Failure of Grantor to make any payment when due on
  the Indebtedness.

  Other Defaults. Failure of Grantor to comply with or to perform any other
  term, obligation, covenant or condition contained in this Agreement or in any
  of the Related Documents or in any other agreement between Lender and Grantor.

  Insolvency. The dissolution or termination of Grantor's existence as a going
  business, the insolvency of Grantor, the appointment of a receiver for any
  part of Grantor's property, any assignment for the benefit of creditors, any
  type of creditor workout, or the commencement of any proceeding under any
  bankruptcy or insolvency laws by or against Grantor.

  Creditor or Forfeiture Proceedings. Commencement of foreclosure or forfeiture
  proceedings, whether by judicial proceeding, self-help, repossession or any
  other method, by any creditor of Grantor or by any governmental agency against
  the Collateral or any other collateral securing the Indebtedness. This
  includes a garnishment of any of Grantor's deposit accounts with Lender.

  Events Affecting Guarantor. Any of the preceding events occurs with respect to
  any Guarantor of any of the Indebtedness or such Guarantor dies or becomes
  incompetent.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a secured
party under the California Uniform Commercial Code. In addition and without
limitation, Lender may exercise any one or more of the following rights and
remedies:

  Accelerate Indebtedness. Lender may declare the entire Indebtedness, including
  any prepayment penalty which Grantor would be required to pay, immediately due
  and payable, without notice.

  Assemble Collateral. Lender may require Grantor to deliver to Lender all or
  any portion of the Collateral and any and all certificates of title and other
  documents relating to the Collateral. Lender may require Grantor to assemble
  the Collateral and make it available to Lender at a place to be designated by
  Lender. Lender also shall have full power to enter upon the property of
  Grantor to take possession of and remove the Collateral. If the Collateral
  contains other goods not covered by this Agreement at the time of
  repossession, Grantor agrees Lender may take such other goods, provided that
  Lender makes reasonable efforts to return them to Grantor after repossession.

  Sell the Collateral. Lender shall have full power to sell, lease, transfer, or
  otherwise deal with the Collateral or proceeds thereof in its own name or that
  of Grantor. Lender may sell the Collateral at public auction or private sale.
  Unless the Collateral threatens to decline speedily in value or is of a type
  customarily sold on a recognized market, Lender will give Grantor reasonable
  notice of the time after which any private sale or any other intended
  disposition of the Collateral is to be made. The requirements of reasonable
  notice shall be met if such notice is given at least ten (10) days, or such
  lesser time as required by state law, before the time of the sale or
  disposition. All expenses relating to the disposition of the Collateral,
  including without limitation the expenses of retaking, holding, insuring,
  preparing for sale and selling the Collateral, shall become a part of the
  Indebtedness secured by this Agreement and shall be payable on demand, with
  interest at the Note rate from date of expenditure until repaid.

  Appoint Receiver. To the extent permitted by applicable law, Lender shall have
  the following rights and remedies regarding the appointment of a receiver: (a)
  Lender may have a receiver appointed as a matter of right, (b) the receiver
  may be an employee of Lender and may serve without bond, and (c) all fees of
  the receiver and his or her attorney shall become part of the Indebtedness
  secured by this Agreement and shall be payable on demand, with interest at the
  Note rate from date of expenditure until repaid.

  Collect Revenues, Apply Accounts. Lender, either itself or through a receiver,
  may collect the payments, rents, income, and revenues from the Collateral.
  Lender may at any time in its discretion transfer any Collateral into its own
  name or that of its nominee and receive the payments, rents, income, and
  revenues therefrom and hold the same as security for the Indebtedness or apply
  it to payment of the Indebtedness in such order of preference as Lender may
  determine. Insofar as the Collateral consists of accounts, general
  intangibles, insurance policies, instruments, chattel paper, choses in action,
  or similar property, Lender may demand, collect, receipt for, settle,
  compromise, adjust, sue for, foreclose, or realize on the Collateral as Lender
  may determine, whether or not Indebtedness or Collateral is then due. For
  these purposes, Lender may, on behalf of and in the name of Grantor, receive,
  open and dispose of mail addressed to Grantor; change any address to which
  mail and payments

================================================================================

  are to be sent; and endorse notes, checks, drafts, money orders, documents of
  title, instruments and items pertaining to payment, shipment, or storage of
  any Collateral. To facilitate collection, Lender may notify account debtors
  and obligors on any Collateral to make payments directly to Lender.

  Obtain Deficiency. If Lender chooses to sell any or all of the Collateral,
  Lender may obtain a judgment against Grantor for any deficiency remaining on
  the Indebtedness due to Lender after application of all amounts received from
  the exercise of the rights provided in this Agreement. Grantor shall be liable
  for a deficiency even if the transaction described in this subsection is a
  sale of accounts or chattel paper.

  Other Rights and Remedies. Lender shall have all the rights and remedies of a
  secured creditor under the provisions of the Uniform Commercial Code, as may
  be amended from time to time. In addition, Lender shall have and may exercise
  any or all other rights and remedies it may have available at law, in equity,
  or otherwise.

  Cumulative Remedies. All of Lender's rights and remedies, whether evidenced by
  this Agreement or the Related Documents or by any other writing, shall be
  cumulative and may be exercised singularly or concurrently. Election by Lender
  to pursue any remedy shall not exclude pursuit of any other remedy, and an
  election to make expenditures or to take action to perform an obligation of
  Grantor under this Agreement, after Grantor's failure to perform, shall not
  affect Lender's right to declare a default and to exercise its remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are a part of
this Agreement:

  Amendments. This Agreement, together with any Related Documents, constitutes
  the entire understanding and agreement of the parties as to the matters set
  forth in this Agreement. No alteration of or amendment to this Agreement shall

  Lender in the State of California. If there is a lawsuit, Grantor agrees upon

                                             --------
  waive the right to any jury trial in any action, proceeding, or counterclaim
  brought by either Lender or Grantor against the other. This Agreement shall be
  governed by and construed in accordance with the laws of the State of

  and expenses of such enforcement. Costs and expenses include Lender's
  attorneys' fees and legal expenses whether or not there is a lawsuit,
  including attorneys' fees and legal expenses for bankruptcy proceedings (and
  including efforts to modify or vacate any automatic stay or injunction),
  appeals, and any anticipated post-judgment collection services. Grantor also
  shall pay all court costs and such additional fees as may be directed by the
  court.

  Caption Headings. Caption headings in this Agreement are for convenience
  purposes only and are not to be used to interpret or define the provisions of
  this Agreement.

  Multiple Parties; Corporate Authority. All obligations of Grantor under this
  Agreement shall be joint and several, and all references to Grantor shall mean
  each and every Grantor. This means that each of the persons signing below is
  responsible for all obligations in this Agreement.

  Notices. All notices required to be given under this Agreement shall be given
  in writing and shall be effective when actually delivered or when deposited
  with a nationally recognized overnight courier or deposited in the United
  States mail, first class, postage prepaid, addressed to the party, to whom the
  notice is to be given at the address shown above. Any party may change its
  address for notices under this Agreement-by giving formal written notice to
  the other parties, specifying that the purpose of the notice is to change the
  party's address. To the extent permitted by applicable law, if there is more
  than one Grantor, notice to any Grantor will constitute notice to all
  Grantors. For notice purposes, Grantor agrees to keep Lender informed at all
  times of Grantor's current address(es).

  Power of Attorney. Grantor hereby appoints Lender as its true and lawful
  attorney-in-fact, irrevocably, with full power of substitution to do the
  following: (a) to demand, collect, receive, receipt for, sue and recover all
  sums of money or other property which may now or hereafter become due, owing
  or payable from the Collateral; (b) to execute, sign and endorse any and all
  claims, instruments, receipts, checks, drafts or warrants issued in payment
  for the Collateral; (c) to settle or compromise any and all claims arising
  under the Collateral, and, in the place and stead of Grantor, to execute and
  deliver its release and settlement for the claim; and (d) to file any claim or
  claims or to take any action or institute or take part in any proceedings,
  either in its own name or in the name of Grantor, or otherwise, which in the
  discretion of Lender may seem to be necessary or advisable. This power is
  given as security for the Indebtedness, and the authority hereby conferred is
  and shall be irrevocable and shall remain in full force and effect until
  renounced by Lender.

  Preference Payments. Any monies Lender pays because of an asserted preference
  claim in Borrower's bankruptcy will become a part of the Indebtedness and, at
  Lender's option, shall be payable by Borrower as provided above in the
  "EXPENDITURES BY LENDER" paragraph.

  Severability. If a court of competent jurisdiction finds any provision of this
  Agreement to be invalid or unenforceable as to any person or circumstance,
  such finding shall not render that provision invalid or unenforceable as to
  any other persons or circumstances. If feasible, any such offending provision
  shall be deemed to be modified to be within the limits of enforceability or
  validity; however, if the offending provision cannot be so modified, it shall
  be stricken and all other provisions of this Agreement in all other respects
  shall remain valid and enforceable.

  Successor Interests. Subject to the limitations set forth above on transfer of
  the Collateral, this Agreement shall be binding upon and inure to the benefit
  of the parties, their successors and assigns.

  Waiver. Lender shall not be deemed to have waived any rights under this
  Agreement unless such waiver is given in writing and signed by Lender. No
  delay or omission on the part of Lender in exercising any right shall operate
  as a waiver of such right or any other right. A waiver by Lender of a
  provision of this Agreement shall not prejudice or constitute a waiver of
  Lender's right otherwise to demand strict compliance with that provision or
  any other provision of this Agreement. No prior waiver by Lender, nor any
  course of dealing between Lender and Grantor, shall constitute a waiver of any
  of Lender's rights or of any of Grantor's obligations as to any future
  transactions. Whenever the consent of Lender is required under this Agreement,
  the granting of such consent by Lender in any instance shall not constitute
  continuing consent to subsequent instances where such consent is required and
  in all cases such consent may be granted or withheld in the sole discretion of
  Lender.

  Waiver of Co-obligor's Rights. If more than one person is obligated for the
  Indebtedness, Borrower irrevocably waives, disclaims and relinquishes all
  claims against such other person which Borrower has or would otherwise have by
  virtue of payment of the Indebtedness or any part thereof, specifically
  including but not limited to all rights of indemnity, contribution or
  exoneration.

ADDITIONAL PROVISION. If any law is passed that requires additional action on
the part of Lender, Grantor shall fully cooperate with Lender in complying with
the law and accordingly, shall reimburse Lender for all costs and expenses which
Lender incurs to comply with the law.

Agreement provided for, among other things, a Committed Revolving Line in the
original principal amount of One Million Two Hundred Thousand Dollars
($1,200,000) and a Committed Equipment Line in the original principal amount of

the "Indebtedness."

2.  DESCRIPTION OF COLLATERAL AND GUARANTIES. Repayment of the Indebtedness is
    ----------------------------------------
secured by the Collateral as described in the Loan Agreement.

Hereinafter, the above-described security documents and guaranties, together
with all other documents securing repayment of the Indebtedness shall be
referred to as the "Security Documents". Hereinafter, the Security Documents,
together with all other documents evidencing or securing the Indebtedness shall
be referred to as the "Existing Loan Documents".

3.  DESCRIPTION OF CHANGE IN TERMS.
    ------------------------------

    A.  Waiver of Covenant Default.
        --------------------------

        1.   Bank hereby waives Borrower's existing default under the Loan
             Agreement by virtue of Borrower's failure to comply with the
             Profitability covenant as of the quarter ended December 31, 1998.
             Bank's waiver of Borrower's compliance of this covenant shall apply
             only to the foregoing period. Accordingly, for the quarter ending
             March 31, 1999, Borrower shall be in compliance with this covenant.

             Bank's agreement to waive the above-described default (1) in no way
             shall be deemed an agreement by Bank to waive Borrower's compliance
             with the above-described covenant as of all other dates and (2)
             shall not limit or impair the Bank's right to demand strict
             performance of this covenant as of all other dates and (3) shall
             not limit or impair the Bank's right to demand strict performance
             of all other covenants as of any date.

    ------------------
necessary to reflect the changes described above.

    -------------------
understands and agrees that in modifying the existing Indebtedness, Bank is
relying upon Borrower's representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to
this Loan Modification Agreement, the terms of the Existing Loan Documents
remain unchanged and in full force and effect. Bank's agreement to modifications
to the existing Indebtedness pursuant to this Loan Modification Agreement in no
way shall obligate Bank to make any future modifications to the Indebtedness.
Nothing in this Loan Modification Agreement shall constitute a satisfaction of
the Indebtedness. It is the intention of Bank and Borrower to retain as liable
parties all makers and endorsers of Existing Loan Documents, unless the party is
expressly released by Bank in writing. No maker, endorser, or

guarantor will be released by virtue of this Loan Modification Agreement. The
terms of this paragraph apply not only to this Loan Modification Agreement, but
also to all subsequent loan modification agreements.

          3.   Section 6.7 entitled "Financial Covenants" is hereby amended in

               Coverage of at least 2.00 to 1.00.

          4.   The following defined terms as set forth in Section 13.1 entitled

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

          1.   Bank hereby waives Borrower's existing defaults under the Loan
               Agreement by virtue of Borrower's failure to comply with the

               dates and (2) shall not limit or impair the Bank's right to
