This Loan and Security Agreement is entered into on the above date between
GREYROCK BUSINESS CREDIT, a Division of NationsCredit Commercial Corporation
(GBC), whose address is 10880 Wilshire Blvd., Suite 950, Los Angeles, CA 90024
and the borrowers named above (jointly and severally, BORROWER), each of whose
chief executive office is located at the above address (BORROWER'S ADDRESS). The
Schedule to this Agreement (the SCHEDULE) being signed concurrently is an
integral part of this Agreement. (Definitions of certain terms used in this
Agreement are set forth in Section 8 below.)

1.  LOANS.

  1.1 LOANS. GBC will make loans to Borrower (the LOANS), in amounts determined
by GBC in its good faith business judgment, 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 rates 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.
Interest may, in GBC's discretion, be 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 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.

  2.1 SECURITY INTEREST. To secure the payment and performance of all of the
Obligations when due, Borrower hereby grants to GBC 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 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.

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 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 (regardless of whether
considered in a proceeding at law or in equity) and by bankruptcy, fraudulent
conveyance, 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 material law or any
material agreement or instrument which is binding upon Borrower or its property,
and

        GREYROCK BUSINESS CREDIT                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------


(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
present trade names of Borrower and all of Borrower's prior names and trade
names, in each case used by Borrower during the four years prior to the date
hereof. 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 unless, prior to such time as any Collateral shall have become
a fixture, GBC shall have obtained a first-priority perfected security interest
therein subject only to permitted liens. 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 reasonable best efforts to cause such third party to
execute and deliver to GBC, in form reasonably 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, in
all material respects, with all the material terms of, any lease of real
property where any of the Collateral now or in the future may be located.
Notwithstanding the foregoing provisions of this Section 3.4, it is understood
and agreed that Borrower shall be permitted to make the following sales
("Permitted Asset Sales"): (i) sell Inventory in the ordinary course of business
and (ii) so long as no Event of Default has occurred and is continuing (a)
dispose in the ordinary course of business of items of Equipment which have
become worn out or obsolete in the reasonable opinion of the executive
management of Borrower, (b) sell Equipment in the ordinary course and in good
faith, arm's length transaction and (c) sell or otherwise dispose, in good
faith, arm's length transactions, Collateral not having, in the aggregate (for
all locations), a fair market value not exceeding $500,000 from the locations
("Proposed Discontinued Locations") set forth in the Schedule under the caption
"Proposed Discontinued Locations". Further, it is understood and agreed that the
provisions of the fifth and sixth sentences of this Section 3.4 shall not apply
to Collateral located at any of the Proposed Discontinued Locations.

  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 (except, in the case of unaudited
financial statements, for the absence of footnotes and, also in the case of
unaudited financial statements as at and for periods other than fiscal year end,
subject to normal year-end adjustments) and now and in the future will, in all
material respects, 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.




                                      -2-
<PAGE>   3

  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 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
$100,000 or more, or involving $250,000 or more in the aggregate.

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

4.  RECEIVABLES.

  4.1 REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and warrants
to GBC 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.

  4.2 REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. Borrower
represents and warrants to GBC as follows: All statements made and all unpaid
balances appearing in all invoices, instruments and other documents evidencing
the Receivables are and shall be true and correct and all such invoices,
instruments and other documents and all of Borrower's books and records are and
shall be genuine and in all respects what they purport to be, and all
signatories and endorsers have the capacity to contract. All sales and other
transactions underlying or giving rise to each Receivable shall comply with all
applicable laws and governmental rules and regulations. 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 as to borrower 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 in all material
respects of all of the foregoing (such warranty being limited to Borrower's
knowledge in cases where any of the foregoing was not prepared by Borrower).
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, promptly 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 an Event of Default has occurred and is
continuing. 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
provided that if no Event of Default has occurred and is continuing, proceeds of
Borrower's Inventory sold in the ordinary course of business shall not be
applied to the principal balance of the Term Loan (as defined in the Schedule).



                                      -3-
<PAGE>   4


  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
the occurrence and during the continuation of any Event of Default, Borrower
shall (i) not accept any return without GBC's prior written consent, (ii) hold
the returned Inventory in trust for GBC, (iii) segregate all returned Inventory
from all of Borrower's other property, (iv) conspicuously label the returned
Inventory as GBC's property, and (v) promptly notify GBC of the return of any
Inventory, specifying the 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.

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 GBC, in such form and amounts as GBC may
reasonably require, and Borrower shall provide evidence of such insurance to
GBC, so that GBC is satisfied that such insurance is, at all times, in full
force and effect. All such insurance policies shall name GBC as an additional
loss payee, and shall contain a lenders loss payee endorsement in form
reasonably acceptable to GBC. Upon receipt of the proceeds of any such
insurance, GBC shall apply such proceeds in reduction of the Obligations as GBC
shall determine in its sole discretion, except that, provided no Default or
Event of Default has occurred and is continuing, (i) proceeds totaling $100,000
or less per casualty shall be permitted to be paid directly to Borrower and
shall be used by Borrower for the repair, replacement or restoration of the
property or assets on account of which such proceeds were paid and (ii)
proceeds, totaling more than $100,000, but less than $500,000 per casualty
occurrence, shall be paid directly to GBC but shall promptly be released by GBC
to Borrower and shall be used by Borrower for the repair, replacement or
restoration of the property or assets on account of which such proceeds were
paid. GBC may require reasonable assurance that the insurance proceeds so
released will be so used. If Borrower fails to provide or pay for any insurance,
GBC may, but is not obligated to, obtain the same at Borrower's expense.
Borrower shall promptly deliver to GBC copies of all reports made to insurance
companies.

  5.2 REPORTS. Borrower, at its expense, shall provide GBC 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 GBC 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, GBC, or its agents, shall have the right to inspect the
Collateral, and the right to audit and copy Borrower's books and records. GBC
shall take reasonable steps to keep confidential all information obtained in any
such inspection or audit, but GBC 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 GBC's then current standard charge
for the same), plus reasonable out-of-pockets expenses. Borrower shall not be
charged more than $3,000 per audit (plus reasonable out-of-pockets expenses),
nor shall audits be done more frequently than two times per calendar year,
provided that the foregoing limits shall not apply after the occurrence and
during the continuance of a Default or Event of Default, nor shall they restrict
GBC'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



                                      -4-
<PAGE>   5

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.

  5.4 REMITTANCE OF PROCEEDS. All proceeds arising from the sale or other
disposition of any Collateral shall be delivered, in kind, by Borrower to GBC in
the original form in which received by Borrower not later than the following
business day after receipt by Borrower, to be applied (subject to Section 4.4
above) to the Obligations in such order as GBC shall determine; provided that,
if no Default or Event of Default has occurred and is continuing, the foregoing
provisions of this Section 5.4 shall not apply to proceeds arising from the
following: the sales referred to in clauses (ii)(a)-(c) of Section 3.4 above
(collectively, "Specified Asset Sales"). Except for the proceeds arising from
Specified Asset Sales, 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 GBC.
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 GBC's prior written consent, do any of the following: (i)
merge or consolidate with another corporation or entity; (ii) acquire any
assets, except in the ordinary course of business; (iii) enter into any other
transaction outside the ordinary course of business; (iv) sell or transfer any
Collateral, except that, provided no Event of Default has occurred and is
continuing, Borrower may make Permitted Asset Sales (and GBC shall promptly
execute and deliver such UCC and other releases as are reasonably necessary in
connection therewith); (v) store any Inventory or other Collateral with any
warehouseman or other third party; (vi) sell any Inventory on a sale-or-return,
guaranteed sale, consignment, or other contingent basis; (vii) make any loans of
any money or other assets other than extensions of trade credit in the ordinary
course of business and reasonable travel and entertainment expenses to employees
in the ordinary course of business; (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 (it being understood and agreed
that (a) Borrower's entering into capitalized leases or incurring purchase money
indebtedness, in each case for assets to be used in Borrower's business, and for
all such cases together not consisting in the aggregate of more than $1,000,000
of principal indebtedness at any time outstanding, and (b) a Borrower incurring
debt to another Borrower, shall not be deemed to be outside of the ordinary
course nor to have a material adverse effect on Borrower or on the prospect of
the Obligations); (ix) except for guaranties by a Borrower named above of the
obligations of another Borrower named above or of a subsidiary of such Borrower
or other Borrower under real property leases which are not prohibited hereunder,
and except for the existing guarantees by Cerplex, Inc. of the obligations of
Cerplex Limited (UK) to BT Repair Services Limited and British
Telecommunications plc. guarantee or otherwise become liable with respect to the
obligations of another party or entity; (x) pay or declare any dividends on
Borrower's stock (except for dividends payable solely in stock of Borrower);
(xi) redeem, retire, purchase or otherwise acquire, directly or indirectly, any
of Borrower's stock; (xii) make any change in Borrower's capital structure which
would have a material adverse effect on Borrower or on the prospect of repayment
of the Obligations; or (xiii) 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 GBC with respect to any Collateral or in any manner
relating to Borrower, Borrower shall, without expense to GBC, make available
Borrower and its officers, employees and agents, and Borrower's books and
records, without charge, to the extent that GBC 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 GBC in writing of
any change in its senior executive 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 Borrower.

  5.8 FURTHER ASSURANCES. Borrower agrees, at its expense, on request by GBC, to
execute all documents and take all actions, as GBC may deem reasonably necessary
or useful in order to perfect and maintain GBC's perfected security 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 reasonable
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,



                                      -5-
<PAGE>   6

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 and during the continuation 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 until paid in full at a rate equal to the higher of the rates set
forth in Section 2 of the Schedule.

  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 good faith business judgment of
GBC, GBC 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 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

Default, 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 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 GBC 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 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 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

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

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

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

demand, and shall bear interest until paid in full at a rate equal to the higher
of the rates set forth in Section 2 of the Schedule.

  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
ten days prior to the sale, and, in the case of a public sale, notice of the
sale is published at least ten 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)
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 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.

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

9.  GENERAL PROVISIONS.

  9.1 INTEREST COMPUTATION. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by GBC (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by GBC on account of the Obligations three Business Days after receipt
by GBC of immediately available funds. GBC shall not, however, be required to
credit Borrower's account for the amount of any item of payment which is
unsatisfactory to GBC in its reasonable business judgment 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.

  9.3 CHARGES TO ACCOUNT. GBC may, in its discretion, require that Borrower pay
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 account
stated (except for reverses and reapplications of payments made and corrections
of errors discovered by GBC), unless Borrower notifies GBC in writing to the
contrary within sixty days after each account is rendered, describing the nature
of any alleged errors or admissions.

  9.5 NOTICES. All notices to be given under this Agreement shall be in writing
and shall be given either personally or by reputable private delivery service or
by regular first-class mail, or certified mail return receipt requested,
addressed to GBC or Borrower at the addresses shown in the heading to this
Agreement (and, in the case of notices to Borrower, also to Reboul, MacMurray,
Hewitt, Maynard & Kristol, 45 Rockefeller Plaza, New York, New York 10111,
attention: Charles D. Uniman), or at any other address designated in writing by
one party to the other party. All notices shall be deemed to have been given
upon delivery in the case of notices personally delivered, 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 GBC 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 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 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 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. Subject to the limitations set forth in Section
5.3 hereof as to audit expenses, 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,
