Amended and Restated Agreement. (Definitions of certain terms used in this
Agreement are set forth in Section 8 below.)

1. LOANS.

  1.1  LOANS. GBC will make loans to Borrower (the "Loans"), in amounts
determined by GBC in its sole discretion, up to the amounts (the "Credit Limit")
shown on the Schedule, provided no Default or Event of Default has occurred and
is continuing. If at any time or for any reason the total of all outstanding
Loans and all other Obligations exceeds the Credit Limit, Borrower shall
immediately pay the amount of the excess to GBC, without notice or demand.

  1.2  INTEREST.  All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule, except where expressly set forth to
the contrary in this Agreement or in another written agreement signed by GBC and
Borrower. Interest shall be payable monthly, on the last day of the month.

the same shall thereafter bear interest at the same rate as the other Loans.

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

2. SECURITY INTEREST.

all of Borrower's Deposit Accounts, all money, all collateral in which GBC is
granted a security interest pursuant to any other present or future agreement,
all property * now or at any time in the future in GBC'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.

  * OF BORROWER

3. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

  In order to induce GBC to enter into this Agreement and to make Loans,
Borrower represents and warrants to GBC 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 

                                      -1-
<PAGE>
 
Greyrock Business Credit        Amended and Restated Loan and Security Agreement
--------------------------------------------------------------------------------

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
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 GBC 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 GBC at least 30 days prior written
notice before opening any additional place of business, changing its chief
executive office, or moving any of the Collateral to a location other than
Borrower's Address or one of the locations set forth on the Schedule.

  3.4  TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will at all
times in the future be, the sole owner of all the Collateral, except for items
of Equipment which are leased by Borrower. The Collateral now is and will remain
free and clear of any and all liens, charges, security interests, encumbrances
and adverse claims, except for Permitted Liens. GBC 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 GBC 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 requested by GBC, use its
best efforts to cause such third party to execute and deliver to GBC, in form
acceptable to GBC, such waivers and subordinations as GBC shall specify, so as
to ensure that GBC's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. Borrower will keep in full force
and effect, and will comply with all the terms of, any lease of real property
where any of the Collateral now or in the future may be located.

  3.5 MAINTENANCE OF COLLATERAL.  Borrower will maintain the Collateral in good
working condition, ordinary wear and tear excepted, and Borrower will not use
the Collateral for any unlawful purpose. Borrower will immediately advise GBC 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 GBC 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 GBC and the date hereof, there has been no material
adverse change in the financial condition or business of Borrower. Borrower is
now and will continue to be solvent.

  3.8  TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has timely
filed, and will timely file, all tax returns and reports required by 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 GBC in writing of the commencement of, and any material development in,
the proceedings, and (iii) posts bonds or takes any other steps required to keep
the contested taxes from becoming a lien upon any of the Collateral.  Borrower
is unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or any other governmental agency. Borrower shall, at all
times, utilize the services of an 

                                      -2-

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 may
result, either separately or in the aggregate, in any material adverse change in
the financial condition or business of Borrower, or in any material impairment
in the ability of Borrower to carry on its business in substantially the same
manner as it is now being conducted. Borrower will promptly inform GBC in
writing of any claim, proceeding, litigation or investigation in the future
threatened or instituted by or against Borrower involving any single claim of
$50,000 or more, or involving $100,000 or more in the aggregate.

lawful business purposes.

undisputed, bona fide, existing, unconditional obligation of the Account Debtor
created by the sale, delivery, and acceptance of goods or the rendition of
services, in the ordinary course of Borrower's business, and (ii) meet the
eligibility requirements set forth in Section 8 below.

represents and warrants to GBC as follows: All statements made and all unpaid

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.  All signatures and
indorsements on all documents, instruments, and agreements relating to all

agreements are and shall be legally enforceable in accordance with their terms.

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

  4.4  COLLECTION OF RECEIVABLES. Borrower shall have the right to collect all
Receivables, unless and until a Default or an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
GBC, and Borrower shall deliver all such payments and proceeds to GBC, within
one business day after receipt of the same, in their original form, duly
endorsed, to be applied to the Obligations in such order as GBC shall determine.

  4.5  DISPUTES. Borrower shall notify GBC promptly of all disputes or claims
relating to Receivables on the regular reports to GBC.  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 GBC on the regular reports provided to GBC, (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 GBC). In the event any attempted return occurs after

reason for such return, the location and condition of the returned Inventory,
and on GBC's request deliver such returned Inventory to GBC.

  4.7  VERIFICATION. GBC may, from time to time, verify directly with the
respective Account Debtors the validity, amount and other matters relating to
the Receivables, by means of mail, telephone or otherwise, either in the name of
Borrower or GBC or such other name as GBC may choose, and GBC or its designee
may, at any time, notify Account Debtors that it has a security interest in the
Receivables.

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

business day's notice, GBC, or its agents, shall have the right to inspect the

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 GBC's written consent, which may be conditioned upon
such accounting firm, service bureau or other third party agreeing to give GBC
the same rights with respect to access to books and records and related rights
as GBC has under this Agreement. **

then Borrower shall not be obligated to remit to GBC the proceeds of the sale of
Equipment which is sold in the ordinary course of business, in a good-faith
arm's length transaction. Except for the proceeds of the sale of Equipment as
set forth above, Borrower shall not commingle proceeds of Collateral with any of

apart from such other funds and property and in an express trust for GBC.
Nothing in this Section limits the restrictions on disposition of Collateral set
forth elsewhere in this Agreement.

records, without charge, to the extent that GBC may deem them reasonably
necessary in order to prosecute or defend any such suit or proceeding.

interest in the Collateral, and in order to fully consummate the transactions
contemplated by this Agreement.

  5.9 INDEMNITY. Borrower hereby agrees to indemnify GBC and hold GBC harmless
from and against any and all claims, debts, liabilities, demands, obligations,
actions, causes of action, penalties, costs and expenses (including attorneys'
fees), of every nature, character and description, which GBC may sustain or
incur based upon or arising out of any of the Obligations, any actual or alleged
failure to collect and pay over any withholding or other tax relating to
Borrower or its employees, any relationship or agreement between GBC and
Borrower, any actual or alleged failure of GBC to comply with any writ of
attachment or other legal process relating to Borrower or any of its property,
or any other matter, cause or thing whatsoever occurred, done, omitted or
suffered to be done by GBC relating to Borrower or the Obligations (except any
such amounts sustained or incurred as the result of the gross negligence or
willful misconduct of GBC or any of its directors, officers, employees, agents,
attorneys, or any other person affiliated with or representing GBC).
Notwithstanding any provision in this Agreement to the contrary, the indemnity
agreement set forth in this Section shall survive any termination of this
Agreement and shall for all purposes continue in full force and effect.

6.  TERM.

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

  6.2  EARLY TERMINATION.  This Agreement may be terminated prior to the
Maturity Date as follows: (i) by Borrower, effective three business days after
written notice of termination is given to GBC; or (ii) by GBC at any time after
the occurrence of an Event of Default, without notice, effective immediately. If
this Agreement is terminated by Borrower or by GBC under this Section 6.2,
Borrower shall pay to GBC 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 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 GBC, then on such date Borrower shall provide to GBC
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 GBC's estimation)
likely to become due in connection therewith, to secure all of the Obligations
relating to said letters of credit, pursuant to GBC's then standard form cash
pledge agreement. Notwithstanding any termination of this Agreement, all of
GBC'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 GBC, GBC may, in
its sole discretion, refuse to make any further 

                                      -5-

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

Loans after termination. No termination shall in any way affect or impair any
right or remedy of GBC, nor shall any such termination relieve Borrower of any
Obligation to GBC, 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, GBC shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be reasonably required to terminate GBC's security interests.

  7.2  REMEDIES. Upon the occurrence and during the continuance of any Event of
Default, and at any time thereafter, GBC, 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

be found, and for that purpose Borrower hereby authorizes GBC without judicial
process to enter onto any of Borrower's premises without interference to search

remain on the premises or cause a custodian to remain on the premises in
exclusive control thereof, without charge for so long as GBC deems it reasonably
necessary in order to complete the enforcement of its rights under this
Agreement or any other agreement; provided, however, that should GBC 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 

                                      -6-

    Greyrock Business Credit    Amended and Restated Loan and Security Agreement
    ----------------------------------------------------------------------------

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 GBC 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 GBC at places designated by GBC which are reasonably convenient to
GBC and Borrower, and to remove the Collateral to such locations as GBC 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, GBC 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 GBC 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. GBC shall have the right to conduct
such disposition on Borrower's premises without charge, for such time or times
as GBC deems reasonable, or on GBC's premises, or elsewhere and the Collateral
need not be located at the place of disposition. GBC 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 GBC 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 GBC'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

expenses, costs, liabilities and obligations incurred by GBC 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.

  7.3  STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and GBC
agree that a sale or other disposition (collectively, "sale") of any Collateral
which complies with the following standards will conclusively be deemed to be
commercially reasonable:  (i) Notice of the sale is given to Borrower at least
seven days prior to the sale, and, in the case of a public sale, notice of the
sale is published at least seven days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted; (ii) Notice of the
sale describes the collateral in general, non-specific terms; (iii) The sale is
conducted at a place designated by GBC, with or without the Collateral being
present; (iv) The sale commences at any time between 8:00 a.m. and 6:00 p.m; (v)
Payment of the purchase price in cash or by cashier's check or wire transfer is
required; (vi) With respect to any sale of any of the Collateral. GBC may (but
is not obligated to) direct any prospective purchaser to ascertain directly from
Borrower any and all information concerning the same. GBC 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 GBC's other rights and remedies, Borrower
grants to GBC an irrevocable power of attorney coupled with an interest,
authorizing and permitting GBC (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 GBC agrees to exercise the
following powers in a commercially reasonable manner: (a) Execute on behalf of
Borrower any documents that GBC may, in its sole discretion, deem advisable in
order to perfect and maintain GBC's security interest in the Collateral, or in
order to exercise a right of Borrower or GBC, 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 GBC's Collateral or in which GBC has an interest; (c) Execute on
behalf of Borrower, any invoices relating to any Receivable, any draft against
any Account Debtor and any notice to any Account Debtor, any proof of claim in
bankruptcy, any Notice of Lien, claim of mechanic's, materialman's or other
lien, or assignment or satisfaction of mechanic's, materialman's or other lien;
(d) Take control in any manner of any cash or non-cash items of payment or
proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into GBC's
possession; (e) Endorse all checks and other forms of remittances received by
GBC; (f) Pay, contest or settle any lien, charge, encumbrance, security interest
and adverse claim in or to any of the Collateral, or any judgment based thereon,
or otherwise take any action to terminate or discharge the same; (g) Grant
extensions of time to pay, compromise claims and settle Receivables and General
Intangibles for less than face value and execute all releases and other
documents in connection therewith; (h) Pay any sums required on account of
Borrower's taxes or to secure the release of any liens therefor, or both; (i)

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

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

applied by GBC on account of the Obligations three Business Days after receipt

credit Borrower's account for the amount of any item of payment which is
unsatisfactory to GBC in its discretion, and GBC may charge Borrower's Loan
account for the amount of any item of payment which is returned to GBC unpaid.

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

monetary Obligations in cash to GBC, or charge them to Borrower's Loan account,
in which event they will bear interest at the same rate applicable to the Loans.

  9.4  MONTHLY ACCOUNTINGS.  GBC shall provide Borrower monthly with an account
of advances, charges, expenses and payments made pursuant to this Agreement.
Such account shall be deemed correct, accurate and binding on Borrower and an

describing the nature of any alleged errors or admissions.

and instruments as may be executed in connection herewith are the final, entire
and complete agreement between Borrower and GBC and supersede all prior and

                                                   -----------------
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 GBC 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 GBC shall not waive or diminish
any right of GBC 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 GBC shall be deemed to have been waived by any act or

knowledge of GBC or its agents or employees, but only by a specific written
waiver signed by an authorized officer of GBC 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 GBC on which Borrower is or
may in any way be liable, and notice of any action taken by GBC, unless

or amended, except in a writing executed by Borrower and a duly authorized
officer of GBC.

  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 GBC for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by GBC, 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
GBC 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

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 GBC may be entitled

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

without the prior written consent of GBC, and any prohibited assignment shall be
void. No consent by GBC 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
GBC, 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 GBC, its
directors, officers, employees, agents, accountants or attorneys, shall be
