(Definitions of certain terms used in this Agreement are set forth in Section 8

1.   LOANS.

   1.1 LOANS. Greyrock will make loans to Borrower (the LOANS), in amounts

charged to Borrower's loan account, and the same shall thereafter bear interest
at the same rate as the other Loans.

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

2.  SECURITY INTEREST.

   2.1 SECURITY INTEREST. To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to Greyrock 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, all money, all collateral in which Greyrock
is granted a security interest pursuant to any other present or future
agreement, all property now or at any time in the future in Greyrock's
possession, and all proceeds (including proceeds of any insurance policies,
proceeds of proceeds and claims against third parties), all products of the
foregoing, and all books and records related to any of the foregoing provided
that Collateral shall not include (i) Equipment and Inventory of Borrower which

Borrower and which has a value in the aggregate of less than $4,000,000, or (ii)
deposit accounts maintained outside the United States in the ordinary course of
business of Borrower and deposits therein made in the ordinary course of
business.

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

   In order to induce Greyrock to enter into this Agreement and to make Loans,
Borrower represents and warrants to Greyrock 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), (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

                GREYROCK CAPITAL                    LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

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 Greyrock 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 Greyrock 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 provided
that such notice shall not be required for (i) sales of Inventory in the
ordinary course of business, (ii) disposal in the ordinary course of business of
items of Collateral which have become worn out or obsolete or which are promptly
being replaced, (iii) disposal of Equipment outside the ordinary course of
business not exceeding in the aggregate $250,000 in value in any fiscal year,
and (iv) movement of Equipment within any of the states specified in the
Schedule or within any other jurisdiction notified to Greyrock hereunder in
which Greyrock has taken all necessary action in order to protect and perfect
its security interest therein, and (iv) any and all mobile goods which are of a
type normally used in more than one jurisdiction, and (v) movement of Equipment
outside any of the states specified in the Schedule in the ordinary course of
business and not exceeding in the aggregate $250,000 in value in any fiscal
year.

   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. Greyrock 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 Greyrock and the Collateral against all claims of others. So
long as any Loan is outstanding which is a term loan, 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 reasonably
requested by Greyrock, use its best efforts to cause such third party to execute
and deliver to Greyrock, in form acceptable to Greyrock, such waivers and
subordinations as Greyrock shall specify, so as to ensure that Greyrock's rights
in the Collateral are, and will continue to be, superior to the rights of any
such third party in all material respects. Borrower will keep in full force and
effect, and will comply in all material respects 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, ordinary wear and tear excepted, and Borrower will not use
the Collateral for any unlawful purpose. Borrower will immediately advise
Greyrock 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 Greyrock have been, and will be, prepared 
in conformity with generally accepted accounting principles and now and in 
the future will completely and fairly 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 Greyrock and the date hereof, 
there has been no material adverse change in the financial condition or 
business of Borrower. Borrower is now solvent. If, in the future, Borrower 
fails to be solvent, the same shall constitute an Event of Default.

    3.8 TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has timely
filed, and will timely file, all tax returns and reports required by applicable
law, and Borrower has timely paid, and will timely pay, all applicable 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 Greyrock 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 material liability of Borrower, including
any liability to the Pension Benefit Guaranty Corporation or any other
governmental agency.

<PAGE>

                GREYROCK CAPITAL                    LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

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 applicable laws and regulations,
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 is
reasonably likely to 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 Greyrock in writing of any claim, proceeding, litigation or
investigation in the future threatened or instituted by or against Borrower
involving any single claim of $200,000 or more, or involving $500,000 or more in
the aggregate.

   3.11 USE OF PROCEEDS. All proceeds of all Loans shall be used solely for
lawful business purposes.

   3.12 YEAR 2000 COMPLIANCE. The Borrower has (i) initiated a review and
assessment of all areas within its and each of its subsidiaries' business and
operations (including those affected by suppliers and vendors) that could be
materially adversely affected by the "Year 2000 Problem" (that is, the risk that
computer applications used by the Borrower or any of its subsidiaries (or its
suppliers and vendors) may be unable to recognize and perform properly
date-sensitive functions involving certain dates prior to and any date after
December 31, 1999), (ii) developed a plan and timeline for addressing the Year
2000 Problem on a timely basis, and (iii) to date, implemented that plan in
accordance with that timetable. The Borrower reasonably believes that all
computer applications (including those of its suppliers and vendors) that are
material to its or any of its subsidiaries' business and operations will on a
timely basis be able to perform properly date-sensitive functions for all dates
before and after January 1, 2000 (that is, be "Year 2000 compliant"), except to
the extent that a failure to do so could not reasonably be expected to have
material adverse effect. The Borrower will promptly notify Greyrock in the event
the Borrower discovers or determines that any computer application (including
those of its suppliers and vendors) that is material to its or any of its
subsidiaries' business and operations will not be Year 2000 compliant on a
timely basis, except to the extent that such failure could not reasonably be
expected to have a material adverse effect.

4.  RECEIVABLES.

   4.1 REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and warrants
to Greyrock as follows: Each Receivable with respect to which Loans are
requested by Borrower shall, on the date each Loan is requested and made,
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 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 Greyrock as follows: to the best of Borrower's
knowledge (after reasonable inquiry) 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 to the best of
Borrower's knowledge (after reasonable inquiry) all signatories and endorsers
have the capacity to contract. All sales and other transactions underlying or
giving rise to each Receivable shall comply with all applicable laws and
governmental rules and regulations. to the best of Borrower's knowledge (after
reasonable inquiry) All signatures and indorsements 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. While the
Non-Streamlined Facility (as defined in the Schedule) is in effect Borrower
shall deliver to Greyrock transaction reports and loan requests, schedules and
assignments of all Receivables, and schedules of collections, all on Greyrock's
standard forms; provided, however, that Borrower's failure to execute and
deliver the same shall not affect or limit Greyrock's security interest and
other rights in all of Borrower's Receivables, nor shall Greyrock's failure to
advance or lend against a specific Receivable affect or limit Greyrock's
security interest and other rights therein. If requested by Greyrock, Borrower
shall furnish Greyrock with copies (or, at Greyrock'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 to the best of its knowledge the genuineness
of all of the foregoing. Borrower shall also furnish to Greyrock an aged
accounts receivable trial balance in such form and at such intervals as Greyrock
shall request. In addition, Borrower shall deliver to Greyrock the originals of
all material 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.

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

    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.
While the Non-Streamlined Facility (as defined in the Schedule) is in effect
Borrower shall hold all payments on, and proceeds of, Receivables in trust
for Greyrock, and Borrower shall deliver all such payments and proceeds to
Greyrock, within one business day after receipt of the same, by wire transfer to
be applied to the Obligations in such order as Greyrock shall determine and
Borrower shall provide Greyrock with a list of all checks and remittances so
received within one Business Day after receipt of the same (and, if requested by
Greyrock, copies of the checks).

    4.5 DISPUTES. Borrower shall notify Greyrock promptly of all disputes or
claims known to Borrower relating to Receivables on the regular reports to
Greyrock. Borrower shall not forgive, 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 Greyrock on the regular reports provided to
Greyrock; (ii) no Default or Event of Default has occurred and is continuing;
and (iii) taking into account all such settlements and forgiveness, the total
outstanding Loans and other Obligations will not exceed the Credit Limit.

    4.6 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 Greyrock if requested by Greyrock). In the event any
attempted return occurs after the occurrence of any Event of Default, Borrower

Inventory from all of Borrower's other property, (iv) conspicuously label 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 Greyrock or such other name as Greyrock may choose, and Greyrock or
its designee may, at any time, notify Account Debtors that it has a security
interest in the Receivables.

   4.8 NO LIABILITY. Greyrock 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 Greyrock 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 Greyrock from liability for
its own gross negligence or willful misconduct.

5.  ADDITIONAL DUTIES OF THE BORROWER.

   5.1 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 Greyrock, in amounts and on forms customary in
Borrower's business, and Borrower shall provide evidence of such insurance to
Greyrock, so that Greyrock is satisfied that such insurance is, at all times, in
full force and effect. All such insurance policies shall name Greyrock as an
additional loss payee, and shall contain a lenders loss payee endorsement in
form reasonably acceptable to Greyrock. Upon receipt of the proceeds of any such
insurance, Greyrock shall apply such proceeds in reduction of the Obligations as
Greyrock shall determine in its sole discretion, except that, provided no
Default or Event of Default has occurred and is continuing, Greyrock 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. Greyrock may
require reasonable assurance that the insurance proceeds so released will be so
used. If Borrower fails to provide or pay for any insurance, Greyrock may, but
is not obligated to, obtain the same at Borrower's expense. Borrower shall
promptly deliver to Greyrock copies of all reports made to insurance companies
relating to losses over $100,000.

   5.2 REPORTS. Borrower, at its expense, shall provide Greyrock 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 Greyrock shall from time to time reasonably
specify.

   5.3 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times, and on one
business day's notice, Greyrock, or its agents, shall have the right to inspect
the Collateral, and the right to audit and copy Borrower's books and records.
Greyrock shall take reasonable steps to keep confidential all information
obtained in any such inspection or audit, but Greyrock 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 $600 per person per day (or such higher amount as shall represent
Greyrock's then current standard charge for the same), plus reasonable
out-of-pockets expenses. Borrower shall not be charged more than $5,000 per
fiscal quarter of Borrower (plus reasonable out-of-pockets expenses), nor shall
audits be done more frequently than four times per calendar year, provided that
the foregoing 


                                      -4-
<PAGE>

                GREYROCK CAPITAL                    LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

limits shall not apply after the occurrence of a Default or Event
of Default, nor shall they restrict Greyrock's right to conduct audits at its
own expense (whether or not a Default or Event of Default has occurred).
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 Greyrock's written consent,
which may be conditioned upon such accounting firm, service bureau or other
third party agreeing to give Greyrock the same rights with respect to access to
books and records and related rights as Greyrock has under this Agreement.

   5.4 REMITTANCE OF PROCEEDS. Except for the proceeds of Receivables 
collected on payment of the same while the Streamlined Facility is in effect, 
and except for the proceeds of sales of Receivables permitted by Section 7(3) 
of the Schedule, and except for proceeds of Equipment with sold in good faith 
arm's length transactions for an aggregate purchase price of less than 
$250,000 in any fiscal year.  All proceeds arising from the sale or other 
disposition of any Collateral shall be delivered, in kind, by Borrower to 
Greyrock in the original form in which received by Borrower or by wire 
transfer not later than the following business day after receipt by Borrower, 
to be applied to the Obligations in such order as Greyrock shall determine. 
Notwithstanding the foregoing, if an Event of Default or an event which, with 
notice or passage of time or both, would constitute an Event of Default, has 
occurred and is continuing, all proceeds of Receivables and Equipment shall 
be delivered, in kind, by Borrower to Greyrock in the original form in which 
received by Borrower or by wire transfer not later than the following 
business day after receipt by Borrower, to be applied to the Obligations in 
such order as Greyrock shall determine, without limiting Greyrock's other 
rights and remedies.  Borrower shall not commingle proceeds of Collateral 
with any of Borrower's other funds or property, and shall hold such proceeds 
separate and apart from such other funds and property and in an express trust 
for Greyrock. Nothing in this Section limits the restrictions on disposition 
of Collateral set forth elsewhere in this Agreement.

     5.5 NEGATIVE COVENANTS. Except as may be permitted in the Schedule,
Borrower shall not, without Greyrock's prior written consent, which shall be a
matter of Greyrock's good faith business judgment, 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 that, provided no Default or Event of Default has occurred
and is continuing, Borrower may (a) sell finished Inventory in the ordinary
course of Borrower's business, and (b) if no term loan is outstanding hereunder,
sell Equipment in the ordinary course of business, in good-faith arm's length
transactions; (v) store any Inventory or other Collateral with any warehouseman
or other third party except for (a) temporary storage of Inventory in the
ordinary course of business with a warehouse which has executed and delivered a
bailee agreement in favor of Greyrock in such form as it shall require, (b)
temporary storage of obsolete or unusable equipment preparatory to its sale if
the sale is permitted under this Loan Agreement, (c) temporary storage of
Inventory in the ordinary course of business in connection with sales of such
Inventory in the ordinary course of business for delivery outside the United
States, and (d) temporary storage of Inventory in the ordinary course of
business with vendors to the Borrower, but no Inventory outside the possession
of Borrower under clauses (a) through (d) above shall be deemed to be Eligible
Inventory; (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 except for loans in connection with employee benefit plans and
other loans to employees in the ordinary course of business, in an aggregate
amount at any time outstanding not to exceed $500,000; (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)
except for (a) obligations to indemnify others incurred by Borrower in the
ordinary course of business, (b) obligations to indemnify officers, directors
and employees of Borrower, and (c) guaranties of the obligations of subsidiaries
of Borrower 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
except for repurchases of stock in connection with employee stock purchase plans
in an aggregate amount not to exceed $100,000 in any fiscal year;
    (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) dissolve or elect to dissolve; or (xiv) agree to do any
of the foregoing.

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

   5.7 NOTIFICATION OF CHANGES. Borrower will promptly notify Greyrock in
writing of any change in its chief financial officer or other executive officers
officers or directors, the opening of any new bank account or other deposit
account, and any material adverse change in the business or financial affairs of

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 Greyrock; or (ii) by Greyrock at any time
after the occurrence of an Event of Default, without notice, effective
immediately. If this Agreement is terminated by Borrower Borrower shall pay to
Greyrock a termination fee (the TERMINATION Fee) in the amount shown on the
Schedule. 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 (as it may be extended under
Section 6.1) 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 based upon an application, guarantee,
indemnity or similar agreement on the part of Greyrock, then on such date
Borrower shall provide to Greyrock cash collateral in an amount equal to 110% of
the face amount of all such letters of credit plus all interest, fees and costs
due or (in Greyrock's estimation) likely to become due in connection therewith,
to secure all of the Obligations relating to said letters of credit, pursuant to
Greyrock's then standard form cash pledge agreement. Notwithstanding any
termination of this Agreement, all of Greyrock'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 Greyrock, Greyrock 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 Greyrock, nor shall any such
termination relieve Borrower of any Obligation to Greyrock, 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, Greyrock shall
promptly deliver to Borrower termination statements, requests for reconveyances
and such other documents as may be reasonably required to terminate Greyrock's
security interests.

not consented to by Borrower, which is not bonded against within 20 days); or

excess of $100,000 secured by a Permitted Lien, which is not cured within any

reasonably be expected to have a material adverse effect on Borrower's business
or financial condition; or (i) dissolution except for dissolution of

any such third party under any bankruptcy or insolvency law; or (m) Borrower

or obligations terminates or in any way limits or terminates its subordination
agreement; or (n) any person or persons acting individually or in concert with
others shall acquire beneficial ownership of securities in Borrower representing

material adverse change in Borrower's business or financial condition. Greyrock
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 and during the continuance of any Event of
Default, and at any time thereafter, Greyrock, 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 Greyrock 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 Greyrock deems it
reasonably necessary in order to complete the enforcement of its rights under
this Agreement or any other agreement; provided, however, that should Greyrock
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 Greyrock
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 Greyrock at places designated by Greyrock which are
reasonably convenient to Greyrock and Borrower, and to remove the Collateral to
such locations as Greyrock may deem advisable; (e) Complete the processing,
manufacturing or repair of any Collateral prior to a disposition thereof and,
for such purpose and for the purpose of removal, Greyrock shall have the right
to use Borrower's premises, 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 Greyrock obtains possession of it
or after further manufacturing, processing or repair, at 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. Greyrock shall have
the right to conduct such disposition on Borrower's premises without charge, for
such time or times as Greyrock deems reasonable, or on Greyrock's premises, or
elsewhere and the Collateral need not be located at the place of disposition.
Greyrock 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 Greyrock 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 Greyrock's sole discretion,
to grant extensions of time to pay, compromise claims and settle Receivables,
General Intangibles and the like for less than face value; and (h) 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 Greyrock 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.

Greyrock agree that a

with the following standards will conclusively be deemed to be commercially
reasonable: (i) Notice of the sale is given to Borrower at least 10 days prior

(vi) With respect to any sale of any of the Collateral, Greyrock may (but is not
obligated to) direct any prospective purchaser to ascertain directly from
Borrower any and all information concerning the same. Greyrock 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 and during the continuance of any
Event of Default, without limiting Greyrock's other rights and remedies,
Borrower grants to Greyrock an irrevocable power of attorney coupled with an
interest, authorizing and permitting Greyrock (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 Greyrock
agrees to exercise the following powers in a commercially reasonable manner: (a)
Execute on behalf of Borrower any documents that Greyrock may, in its sole
discretion, deem advisable in order to perfect and maintain Greyrock's security
interest in the Collateral, or in order to exercise a right of Borrower or
Greyrock, 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 Greyrock's Collateral or
in which Greyrock 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;

payment or Collateral that may come into Greyrock's possession; (e) Endorse all

to any of the Collateral, or any judgment based thereon, or otherwise take any

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 Greyrock the same rights
of access and other rights with respect thereto as Greyrock 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 reasonable attorneys' fees incurred by Greyrock 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 Greyrock's
rights under the foregoing power of attorney or any of Greyrock's other rights
under this Agreement be deemed to indicate that Greyrock 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
or other disposition of the Collateral shall be applied by Greyrock first to the
reasonable costs, expenses, liabilities, obligations and attorneys' fees
incurred by Greyrock 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 Greyrock shall determine in its sole
discretion. Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Greyrock for any deficiency.
If Greyrock, in its sole discretion, directly or indirectly enters into a
deferred payment or other credit transaction with any purchaser at any sale of
Collateral, Greyrock 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 Greyrock of the cash therefor.

   7.6 REMEDIES CUMULATIVE. In addition to the rights and remedies set forth in
this Agreement, Greyrock 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 Greyrock and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Greyrock of one or more of its rights or remedies shall not be deemed an
election, nor bar Greyrock from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Greyrock 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.

or may be liable for goods purchased from such Account Debtor or otherwise (but
in that event the amount of the Receivable in excess of the amount owing from
the Borrower to the Account Debtor may be an Eligible Receivable). If more than
50% of the Receivables owing from an Account Debtor are not Eligible

deemed to have been given upon delivery in the case of notices personally
delivered or sent by fax, 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 Greyrock 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 Greyrock 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 Greyrock shall not waive or
diminish any right of Greyrock 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 Greyrock shall be deemed to have been
waived by any act or knowledge of Greyrock or its agents or employees, but only
by a specific written waiver signed by an authorized officer of Greyrock 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 Greyrock on which Borrower is or may in any way be liable, and notice of any
action taken by Greyrock, unless expressly required by this Agreement.

   9.9 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 Greyrock.

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

   9.11 ATTORNEYS FEES AND COSTS. Borrower shall reimburse Greyrock for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Greyrock, 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 Greyrock 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 Greyrock's security interest in, the Collateral; and otherwise represent
Greyrock in any litigation relating to Borrower. If either Greyrock 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
Greyrock 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.

   9.12 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 Greyrock; provided, however,
that Borrower may not assign or transfer any of its rights under this Agreement
without the prior written consent of Greyrock, and any prohibited assignment
shall be void. No consent by Greyrock to any assignment shall release Borrower
from its liability for the Obligations.

   9.13 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.

   9.14 LIMITATION OF ACTIONS. Any claim or cause of action by Borrower against
Greyrock, 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 Greyrock,
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 Greyrock, or on any other person
authorized to accept service on behalf of Greyrock, 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 Greyrock in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

   9.15 PARAGRAPH HEADINGS; CONSTRUCTION. Paragraph headings are only used in
this Agreement for convenience. Borrower and Greyrock 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 Greyrock or Borrower under any
rule of construction or otherwise.

   9.16 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts and
transactions hereunder and all rights and obligations of Greyrock and Borrower
shall be governed by the laws of the State of California. As a material part of
the consideration to Greyrock to enter into this Agreement, Borrower (i) agrees
that all actions and proceedings relating directly or indirectly to this
Agreement shall, at Greyrock's option, be litigated in courts located within
California, and that the exclusive venue therefor shall be Los Angeles 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.

   9.16A CONFIDENTIALITY. Greyrock covenants and agrees, on a continuing basis,
to use reasonable efforts to maintain the confidentiality of and not to disclose
to any person other than its officers, directors, attorneys and accountants,
affiliates, and participants and such other persons to whom Greyrock shall at
any time be required to make such disclosure in accordance with applicable law,
any and all proprietary, trade secret or confidential information provided to or
received by Greyrock from or on account of Borrower or any affiliate of
Borrower, including business plans and forecasts, non-public financial
information, confidential or secret processes, formulae, devices or contractual
information, customer lists, employee relation matters, and any other
information the disclosure of which could reasonably be expected to have a
material adverse impact on the business, finances or operations of Borrower or
its affiliates, PROVIDED, HOWEVER, the foregoing provisions shall not be
effective regarding the disposition of Collateral after an Event of Default.

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

     following:

               (1) RECEIVABLE LOANS. The lesser of (A) 50% of the amount of

     (d)  SELECTING A FACILITY. Throughout the term of this Agreement, either
     the "Streamlined Facility" or the "Non-Streamlined Facility" shall be
     in effect. Borrower shall give Greyrock written notice, at least two
     weeks prior to the date Borrower desires to change from the
     Streamlined Facility to the Non-Streamlined Facility or from the
     Non-Streamlined Facility to the Streamlined Facility. The Facility in
     effect as of the date hereof shall be the Streamlined Facility. If
     Borrower desires to change from the Streamlined Facility to the
     Non-Streamlined Facility, then at least two weeks prior to the date
     the change is to go into effect, Borrower shall provide Greyrock with
     all schedules, reports, assignments, agings and the like which would
     be required under the Non-Streamlined Facility, current as of the date
     of the change, and shall allow Greyrock access to Borrower's books and
     records to conduct Greyrock's normal pre-funding audit. If Borrower
     desires to change from the Non-Streamlined Facility to the Streamlined
     Facility, then, on the date the change is to go into effect, Borrower
     shall pay to Greyrock, in immediately available funds, an amount
     sufficient to reduce the outstanding Obligations to the amount of the
     Credit Limit under the Streamlined Facility.

     (e)  STREAMLINED FACILITY PROVISIONS. While the Streamlined Facility is in
     effect, the following provisions (the "Streamlined Facility
     Provisions") shall apply:

               (1) Daily reporting of transactions and daily schedules and
               assignments of Receivables and schedules of collections, called
               for by Section 4.3 of this Loan Agreement, will not be required.
               Instead, the Borrower shall provide Greyrock with a monthly
               Borrowing Base Certificate, in such form as Greyrock shall from
               time to time specify, within 10 Business Days after the end of
               each month. In the event, as of the end of any month, the total
               of all Loans and all other Obligations exceeds the Credit Limit
               permitted under the Streamlined Facility, Borrower shall
               immediately pay the amount of the excess to Greyrock.

               (2) Delivery of the proceeds of Receivables and other Collateral
               within one business day after receipt, as called for by Sections
               4.4 and 5.4 of the Loan Agreement will not be required.

               (3) The Streamlined Provisions shall immediately terminate if any
               Event of Default or any event which, with notice or passage of
               time or both, would constitute an Event of Default, occurs and is
               continuing.

               (4) Upon termination of the Streamlined Provisions for any
               reason, the Borrower shall, then and thereafter, provide Greyrock
               with the daily reporting of transactions and daily schedules and
               assignments of Receivables and schedules of collections, as
               called for by Section 4.3 of this Agreement, and Borrower shall
               deliver all proceeds

               of Receivables and other Collateral to Greyrock, within one
               business day after receipt, as called for by Sections 4.4 and 5.4
               of this Agreement.

         (f) NEW ZEALAND AND UK RECEIVABLES. Receivables of Borrower's
         affiliates, MAS Technology Limited, a New Zealand corporation, and DMC
         Telecom U.K. Ltd., a Delaware corporation (jointly and severally, the
         "Foreign Affiliates") may be included as Eligible Receivables, provided
         that (i) they meet the other requirements for Eligible Receivables and
         are acceptable to Greyrock in its sole discretion, and (ii) the
         Guaranties and Security Agreements referred to in Section 7(1) below
         have been executed and delivered and are in full force and effect, and
         (iii) Greyrock has a first-priority, perfected security interest in all
         such Receivables, and (iv) all documents, instruments and actions
         recommended by Greyrock's attorneys in the UK and in New Zealand in
         connection with the foregoing have been executed, delivered and taken,
         and (v) Greyrock has confirmed all of the foregoing with its attorneys.

         (g)  TERM LOAN.

               (1) AMOUNT. The amount of the Term Loan shall be in a total
               amount not to exceed $5,000,000.

               (2) DISBURSEMENTS. The Term Loan shall be made in an initial
               disbursement of not less than $2,500,000 and subsequent
               disbursements of not less than $1,000,000. No Term Loans will be
               disbursed after November 30, 1999. Prior to any disbursement of
               the Term Loan, Greyrock shall have completed its analysis of the
               UCC-1 Financing Statements filed by other lenders with respect to
               Borrower relating to Borrower's equipment, and Borrower shall
               cause any such Financing Statements which, in the judgment of
               Greyrock, cover equipment which Greyrock included in its
               calculation of the borrowing base in determining the amount of
               the Term Loan to be terminated of record. The disbursements of
               the Term Loan shall be further conditioned on no Event of Default
               and no event which, with notice or passage of time or both, would
               constitute an Event of Default having occurred and continuing at
               the date the disbursement is to be made and after giving effect
               thereto. Borrower shall give Greyrock a written request for the
               disbursement of the Term Loan at least two Business Days prior to
               the desired date of the disbursement. Term Loans available
               hereunder shall be reduced by the amount of any Loans outstanding
               under Sections 1(b)(2)(D) or 1(c)(3) relating to undrawn Term
               Loans.

               (3) PRINCIPAL INSTALLMENTS. Each Term Loan shall be repaid in 48
               equal monthly installments of principal (the "Monthly Principal
               Installments"), commencing on the first day of the first month
               after the date of the disbursement of the Term Loan and
               continuing on the same day of each succeding month thereafter
               until the earlier of (i) the date the Term Loans have been paid
               in full, or (ii) the date this Loan Agreement terminates by its
               terms or is terminated by either party in accordance with its
               terms, at which date the entire unpaid principal balance of the
               Term Loan plus all accrued interest thereon shall be paid in
               full; provided that the 48 monthly principal installments of any
               Term Loans disbursed in November, 1998 shall commence on January
               1, 1999.

               (4) NOTE. The Term Loan shall be evidenced by a Secured
               Promissory Note of even date herewith made by Borrower to the

                                        of a 360-day year for the actual number
                                        of days elapsed, provided that the
                                        interest rate in effect in each month
                                        shall not be less than 8% per annum, and
                                        provided that the interest charged for
                                        each calendar month, beginning December
                                        1, 1998, shall be a minimum of $20,000,
                                        regardless of the amount of the
                                        Obligations outstanding. The interest
                                        rate applicable to all Loans shall be
                                        adjusted monthly as of the first day of
                                        each month, and the interest to be
                                        charged for each month shall be based on
                                        the highest "Prime Rate" in effect
                                        during said month. "Prime Rate" means
                                        the actual "Reference Rate" or the
                                        substitute therefor of the Bank of
                                        America NT & SA whether or not that rate

$5,000,000              Los Angeles, California                  OCTOBER 1, 1998

         FOR VALUE RECEIVED, the undersigned (the BORROWER) promises to pay to
the order of Greyrock Capital, a division of NationsCredit Commercial
Corporation (GREYROCK), at 10880 Wilshire Blvd. Suite 950, Los Angeles, CA
90024, or at such other address as the holder of this Note shall direct, the
principal sum of $5,000,000 (or such lesser or greater amount as shall
constitute the unpaid principal balance of the Term Loan made pursuant to the
Loan and Security Agreement between the Borrower and Greyrock dated as of
OCTOBER 1, 1998 (the LOAN AGREEMENT).

         The principal amount of this Note shall be repaid as provided in the
Loan Agreement.

         This Note shall bear interest on the unpaid principal balance hereof
from time to time outstanding at a rate equal to the following: A rate equal to
the "Prime Rate" (as defined in the Loan Agreement) plus 1.5% per annum,
calculated on the basis of a 360-day year for the actual number of days elapsed,
provided that the interest rate in effect in each month shall not be less than
8% per annum. The interest rate applicable to all Loans shall be adjusted
monthly as of the first day of each month, and the interest to be charged for
each month shall be based on the highest "Prime Rate" in effect during said
month.

         Accrued interest on this Note shall be payable monthly, in addition to
the principal payments provided above, commencing on NOVEMBER 30, 1998 and
continuing on the last day of each succeeding month. Any accrued interest not
paid when due shall bear interest at the same rate as the principal hereunder.

on a Saturday, Sunday or legal holiday, the due date thereof shall be extended
to the next succeeding business day, and interest shall be payable thereon

paid in full when due, or if any other default or event of default occurs
hereunder, under the Loan Agreement or under any other present or future
instrument, document, or agreement between the Borrower and Greyrock
(collectively, EVENTS OF DEFAULT), Greyrock may, at its option, at any time
thereafter, declare the entire unpaid principal balance of this Note plus all
accrued interest to be immediately due and payable, without notice or demand.
The acceptance of any installment of principal or interest by Greyrock after the
time when it becomes due, as herein specified, shall not be held to establish a
custom, or to waive any rights of Greyrock to enforce payment when due of any
further installments or any other rights, nor shall any failure or delay to
exercise any rights be held to waive the same.

         All payments hereunder are to be applied first to costs and fees
referred to hereunder, second to the payment of accrued interest and the
remaining balance to the payment of principal. Any principal prepayment
hereunder shall be applied against principal payments in the inverse order of
maturity. Greyrock shall have the continuing and exclusive right to apply or
reverse and reapply any and all payments hereunder.
