2.   CREDIT FACILITIES.

     2.1  Loans.  Coast will make loans to Borrower (the "Loans"), in amounts
and in percentages to be determined by Coast in its good faith discretion, up to
the Credit Limit, provided no Default or Event of Default has occurred and is
continuing. In addition, Coast may create reserves against or reduce its advance
rates based upon Eligible Receivables or Eligible Inventory without declaring a
Default or an Event of Default if it determines that there has occurred a
Material Adverse Effect.

     2.2  Letters of Credit.  At the request of Borrower, Coast may, in its sole
discretion, arrange for the issuance of letters of credit for the account of
Borrower (collectively, "Letters of Credit"), by issuing guarantees to the
issuer of the letter of credit or by other means. All Letters of Credit shall be
in form and substance satisfactory to Coast in its sole discretion. The
aggregate face amount of all outstanding Letters of Credit from time to time
shall not exceed the amount shown on the Schedule (the "Letter of Credit
Sublimit"), and shall be reserved against Loans which would otherwise be
available hereunder. Borrower shall pay all bank charges for the issuance of
Letters of Credit. Any payment by Coast under or in connection with a Letter of
Credit shall constitute a Loan hereunder on the date such payment is made. Each
Letter of Credit shall have an expiry date no later than thirty (30) days prior
to the Maturity Date. Borrower hereby agrees to indemnify, save, and hold Coast
harmless from any loss, cost, expense, or liability, including payments made by
Coast, expenses, and reasonable attorneys' fees incurred by Coast arising out of
or in connection with any Letters of Credit. Borrower agrees to be bound by the

guarantied by Coast and opened for Borrower's account or by Coast's
interpretations of any Letter of Credit issued by Coast for Borrower's account,
and Borrower understands and agrees that Coast shall not be liable for any
error, negligence, or mistake, whether of omission or commission, in following
Borrower's instructions or those contained in the Letters of Credit or any
modifications, amendments, or supplements thereto. Borrower understands that
Letters of Credit may require Coast to indemnify the issuing bank for certain
costs or liabilities arising out of claims by Borrower against such issuing
bank. Borrower hereby agrees to indemnify and hold Coast harmless with respect
to any loss, cost, expense, or liability incurred by Coast under any Letter of
Credit as a result of Coast's indemnification of any such issuing bank. The
provisions of this Agreement, as it pertains to Letters of Credit, and any other
present or future documents or agreements between Borrower and Coast relating to
Letters of Credit are cumulative.

3.   INTEREST AND FEES.

     3.1  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. Interest shall be payable monthly, on the last
day of the month. Interest may, in Coast's discretion, be charged to

shall be deemed fully earned on the Closing Date and are nonrefundable.

interest in the following, whether now owned or hereafter acquired, and wherever
located:  All Receivables, Inventory, Equipment, Investment Property, and
General Intangibles, including, without limitation, all of Borrower's Deposit

Coast's possession (including claims and credit balances), and all proceeds of
any of the foregoing (including proceeds of any insurance policies, proceeds of
proceeds, and claims against third parties), all products of any of the
foregoing, and all books and records related to any of the foregoing (all of the

6.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

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

     6.1       Existence and Authority.  Borrower is and will continue to be,
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization.  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.  The execution, delivery and performance
by Borrower of this Agreement, and all other documents contemplated hereby (a)
have been duly and validly authorized, (b) 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), and (c) 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 (d) 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.

     6.2       Name; Trade Names and Styles.  The name of Borrower set forth in
the heading to this Agreement is its exact legal name. Listed on the Schedule
are all prior names of Borrower and all of Borrower's present and prior trade
names. Borrower shall give Coast thirty (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.

     6.3       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 Coast at least thirty
(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.

     6.4       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. Coast 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 Coast and the Collateral against all claims of
others. None of the Collateral now is or will be affixed to any real property in
such a

                                       8
<PAGE>

Coast Business Credit                                Loan and Security Agreement
--------------------------------------------------------------------------------

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 Coast, use its best efforts to cause such
third party to execute and deliver to Coast, in form acceptable to Coast, such
waivers and subordinations as Coast shall specify, so as to ensure that Coast'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.

     6.5       Maintenance of Collateral.  Borrower will maintain the Collateral
in good working condition, and Borrower will not use the Collateral for any
unlawful purpose. Borrower will immediately advise Coast in writing of any
material loss or damage to the Collateral.

     6.6       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 GAAP.

     6.7       Financial Condition, Statements and Reports.  All financial
statements now or in the future delivered to Coast have been, and will be,
prepared in conformity with GAAP (except, in the case of unaudited financial
statements, for the absence of footnotes and subject to normal year-end
adjustments) and now and in the future will 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 Coast and the date
hereof, there has been no Material Adverse Effect. Borrower is now and will
continue to be Solvent.

     6.8       Tax Returns and Payments; Pension Contributions.  Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments, deposits
and contributions now or in the future owed by 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 Coast 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.  As of the date hereof,
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 its successors 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.

     6.9       Compliance with Law.  To the best of Borrower's knowledge,
Borrower has complied, and will comply, in all material respects, with all
provisions of all material foreign, federal, state and local laws and
regulations relating to Borrower, including, but not limited to, the Fair Labor
Standards Act, and those relating to Borrower's ownership of real or personal
property, the conduct and licensing of Borrower's business, and environmental
matters.

     6.10      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 a Material
Adverse Effect. Borrower will promptly inform Coast in writing of any claim,
proceeding, litigation or investigation in the future threatened or instituted
by or against Borrower involving an amount set forth on the Schedule.

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

     6.11      Use of Proceeds. All proceeds of all Loans shall be used solely
for lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation G of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of

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.

     7.2       Representations Relating to Documents and Legal Compliance.
Borrower represents and warrants to Coast 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.
All sales and other transactions underlying or giving rise to each Receivable
shall fully 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 legally enforceable in
accordance with their terms.

     7.3       Schedules and Documents relating to Receivables.  Borrower shall
deliver to Coast via facsimile, unless otherwise directed by Coast, at such
locations and at such intervals as Coast may request, transaction reports and
loan requests, schedules of Receivables, and schedules of collections, all on
Coast's standard forms; provided, however, that Borrower's failure to execute
and deliver the same shall not affect or limit Coast's security interest and
other rights in all of Borrower's Receivables, nor shall Coast's failure to
advance or lend against a specific Receivable affect or limit Coast's security
interest and other rights therein. Loan requests received after 10:30 A.M. Los
Angeles, California time, will not be considered by Coast until the next
Business Day. Together with each such schedule, or later if requested by Coast,
Borrower shall furnish Coast with copies (or, at Coast'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 Coast an aged accounts receivable trial balance
in such form and at such intervals as Coast shall request. In addition, Borrower
shall deliver to Coast the originals of all instruments, chattel paper, security
agreements, guarantees and other documents and property evidencing or securing
any Receivables, upon receipt thereof and in the same form as received, with all
necessary indorsements, all of which shall be with recourse. Borrower shall also
provide Coast with copies of all credit memos as and when requested by Coast.

     7.4       Collection of Receivables.  Borrower shall have the right to
collect all Receivables, unless and until an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Coast, and Borrower shall deliver all such payments and proceeds to Coast within
one (1) Business Day after receipt by Borrower, in their original form, duly
endorsed to Coast, to be applied to the Obligations in such order as Coast shall
determine.  Coast may, in its discretion, require that all proceeds of
Collateral be deposited by Borrower into a lockbox account, or such other
"blocked account" as Coast may specify, pursuant to a blocked account agreement
in such form as Coast may specify.  Coast or its designee may, at any time,
notify Account Debtors that Coast has been granted a security interest in the
Receivables.

     7.5       Remittance of Proceeds.  All proceeds arising from the
disposition of any Collateral shall be delivered to Coast within one (1)
Business Day after receipt by Borrower, in their original form, duly endorsed to
Coast, to be applied to the Obligations in such order as Coast shall determine.
Borrower agrees that it will not commingle proceeds of Collateral with any of
Borrower's other funds or property, but will hold

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

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

     7.6       Disputes.  Borrower shall notify Coast promptly of all disputes
or claims relating to Receivables.  Borrower shall not forgive (completely or
partially), compromise 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: (a) 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 Coast on the regular reports provided to Coast; (b) no Default or
Event of Default has occurred and is continuing; and (c) taking into account all
such discounts settlements and forgiveness, the total outstanding Loans will not
exceed the Credit Limit.  Coast may, at any time after the occurrence of an
Event of Default, settle or adjust disputes or claims directly with Account
Debtors for amounts and upon terms which Coast considers advisable in its
reasonable credit judgment and, in all cases, Coast shall credit Borrower's Loan
account with only the net amounts received by Coast in payment of any
Receivables.

     7.7       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.  In the event any attempted return occurs after the
occurrence of any Event of Default, Borrower shall (a) hold the returned
Inventory in trust for Coast, (b) segregate all returned Inventory from all of
Borrower's other property, (c) conspicuously label the returned Inventory as
subject to Coast's security interest, and (d) immediately notify Coast of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Coast's request deliver such
returned Inventory to Coast.

     7.8       Verification.  Coast 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 Coast or such other name as Coast may choose.

     7.9       No Liability.  Coast 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 Coast 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 Coast from liability for its
own gross negligence or willful misconduct.

8.   ADDITIONAL DUTIES OF THE BORROWER.

     8.1       Financial and Other Covenants. Borrower shall at all times comply
with the financial and other covenants set forth in the Schedule.

     8.2       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 Coast, in such form and amounts as Coast
may reasonably require, and Borrower shall provide evidence of such insurance to
Coast, so that Coast is satisfied that such insurance is, at all times, in full
force and effect.  All liability insurance policies of Borrower shall name Coast
as an additional insured, and all property casualty and related insurance
policies of Borrower shall name Coast as a loss payee thereon and Borrower shall
cause a lender's loss payee endorsement in form reasonably acceptable to Coast.
Upon receipt of the proceeds of any such insurance, Coast shall apply such
proceeds in reduction of the Obligations as Coast shall determine in its sole
discretion, except that, provided no Default or Event of Default has occurred
and is continuing, Coast shall release to Borrower insurance proceeds with
respect to Equipment totaling less than the amount set forth in Section 8 of the
Schedule, which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid.  Coast may
require reasonable assurance that the insurance proceeds so released will be so
used.  If Borrower fails to provide or pay for any insurance, Coast may, but is
not obligated to, obtain the same at

                                       11

Borrower's expense. Borrower shall promptly deliver to Coast copies of all
reports made to insurance companies.

     8.3       Reports.  Borrower, at its expense, shall provide Coast with the

time reasonably specify.

     8.4       Access to Collateral, Books and Records.  At reasonable times but
not less frequently than quarterly and on one (1) Business Day's notice, Coast,
or its agents, shall have the right to perform Audits. Coast shall take
reasonable steps to keep confidential all confidential information obtained in
any Audit, but Coast 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 Audits shall be at Borrower's expense and the charge
for the Audits shall be Seven Hundred Fifty Dollars ($750) per person per day
(or such higher amount as shall represent Coast's then current standard charge
for the same), plus reasonable out-of-pocket expenses. 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 notifying Coast of the same and obtaining the written agreement
from such accounting firm, service bureau or other third party to give Coast the
same rights with respect to access to books and records and related rights as
Coast has under this Loan Agreement. Borrower shall also take all necessary
steps to assure that this material accounting and software, systems and
applications, and those of its accounting firm, service bureau or any other
third party vendor or supplier, will on a timely basis, adequately and
completely address the Year 2000 Problem in all material aspects.

     8.5       Negative Covenants.  Borrower shall not, without Coast's prior
written consent, do any of the following:

               (a)  merge or consolidate with another entity, except in a

(50%) of the ownership interest in the surviving entity immediately after such
merger or consolidation, and (ii) the Borrower is the surviving entity;

               (b)  acquire any assets, except (i) in the ordinary course of
business, or (ii) in a transaction or a series of transactions not involving the

the Schedule;

               (c)  enter into any other transaction outside the ordinary course
of business;

               (e)  store any Inventory or other Collateral with any
warehouseman or other third party;

               (f)  sell any Inventory on a sale-or-return, guaranteed sale,
consignment, or other contingent basis;

               (g)  make any loans of any money or other assets, except (i)

travel advances, employee relocation loans and other employee loans and advances
in the ordinary course of business, and (iii) loans to employees, officers and
directors for the purpose of purchasing equity securities of the Borrower;

               (h)  incur any debts, outside the ordinary course of business,
which would have a Material Adverse Effect;

               (i)  guarantee or otherwise become liable with respect to the
obligations of another party or entity;

               (j)  pay or declare any dividends or distributions on the

               (k)  make any change in Borrower's capital structure which would
have a Material Adverse Effect; or

                                       12

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

               (l)  dissolve or elect to dissolve.

     Transactions permitted by the foregoing provisions of this Section are only
permitted if no Default or Event of Default is continuing or would occur as a
result of such transaction.

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

     8.7       Further Assurances.  Borrower agrees, at its expense, on request
by Coast, to execute all documents and take all actions, as Coast, may deem
reasonably necessary or useful in order to perfect and maintain Coast's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement. Without limiting the foregoing,
such documents and actions may include, without limitation, Borrower's
cooperation with Coast (i) in obtaining a control agreement in form and
substance satisfactory to Coast in its discretion with respect to Collateral
consisting of Deposit Accounts, Investment Property, letter of credit rights and
electronic chattel paper and (ii) in notifying a third party in possession of
Collateral of Coast's security interest and obtaining an acknowledgement from
the third party that it is holding the Collateral for the benefit of Coast.

9.   TERM.

     9.1       Maturity Date.  This Agreement shall continue in effect until 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 one hundred twenty (120) days prior to the Maturity Date or
the next Renewal Date, that such party elects to terminate this Agreement
effective on the Maturity Date or such next Renewal Date. If this Agreement is
renewed under this Section 9.1, Borrower shall pay to Coast a Renewal Fee in the
amount shown in Section 3 of the Schedule. The Renewal Fee shall be due and
payable on the Renewal Date and thereafter shall bear interest at a rate equal
to the rate applicable to the Receivable Loans.

     9.2       Early Termination.  This Agreement may be terminated prior to the
Maturity Date as follows: (a) by Borrower, effective three (3) Business Days
after written notice of termination is given to Coast; or (b) by Coast at any
time after the occurrence of an Event of Default, without notice, effective
immediately. If this Agreement is terminated by Borrower or by Coast under this
Section 9.2, Borrower shall pay to Coast an Early Termination Fee in the amount
shown in Section 3 of the Schedule. The Early Termination Fee shall be due and
payable on the effective date of termination and thereafter shall bear interest
at a rate equal to the rate applicable to the Receivable Loans.

     9.3       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, the
Renewal Date, or on any earlier effective date of termination, there are any
outstanding Letters of Credit issued by Coast or issued by another institution
based upon an application, guarantee, indemnity or similar agreement on the part
of Coast, then on such date Borrower shall provide to Coast cash collateral in
an amount equal to the face amount of all such Letters of Credit plus all
interest, fees and costs due or to become due in connection therewith, to secure
all of the Obligations relating to said Letters of Credit, pursuant to Coast's
then standard form cash pledge agreement. Notwithstanding any termination of
this Agreement, all of Coast'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
Coast, Coast 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 Coast, nor shall any such termination relieve Borrower of any
Obligation to Coast, 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, Coast shall promptly

other documents as may be required to fully terminate Coast's security
interests.

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

          (n)  Borrower or any guarantor of any of the Obligations makes any
payment on account of any indebtedness or obligation which has been subordinated
to the Obligations, other than as permitted in the applicable subordination
agreement, or if any Person who has subordinated such indebtedness or
obligations terminates or in any way limits his subordination agreement; or

          (o)  Except as permitted under Section 8.5(a), Borrower shall suffer

          (p)  Borrower shall generally not pay its debts as they become due, or
Borrower shall conceal, remove or transfer any part of its property, with intent

conveyance or similar law; or

          (q)  there shall be any Material Adverse Effect.

Coast may cease making any Loans or extending any credit hereunder during any of
the above cure periods.

     10.2 Remedies.  Upon the occurrence, and during the continuance, of any
Event of Default, Coast, 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 Coast 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 Coast deems it reasonably
necessary in order to complete the enforcement of its rights under this
Agreement or any other agreement; provided, however, that should Coast 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

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 Coast at places designated by Coast which are reasonably
convenient to Coast and Borrower, and to remove the Collateral to such locations
as Coast 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, Coast shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge. Coast is hereby granted a license or other right to use, without charge,
Borrower's labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and Borrower's
rights under all licenses and all franchise agreements shall inure to Coast's
benefit;

          (f)  Sell, lease or otherwise dispose of any of the Collateral, in its
condition at the time Coast 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

                                       15

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

adjourn any such sale from time to time without notice other than oral
announcement at the time scheduled for sale. Coast shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Coast deems reasonable, or on Coast's premises, or elsewhere and the
Collateral need not be located at the place of disposition. Coast 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 Coast 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 Coast's sole
discretion, to grant extensions of time to pay, compromise claims and settle
Receivables 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 attorneys' fees, expenses, costs, liabilities and obligations incurred
by Coast (including attorneys' fees and expenses incurred in connection with
bankruptcy) with respect to the foregoing shall be due from the Borrower to
Coast on demand. Coast may charge the same to Borrower's loan account, and the
same shall thereafter bear interest at the same rate as is applicable to the
Receivable Loans.  Without limiting any of Coast's rights and remedies, from and
after the occurrence of any Event of Default, the interest rate applicable to
the Obligations shall be increased by an additional three percent per annum.

     10.3 Standards for Determining Commercial Reasonableness. Borrower and
Coast 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:

          (a)  Notice of the sale is given to Borrower at least five (5) days
prior to the sale, and, in the case of a public sale, notice of the sale is
published at least five (5) days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted;

          (b)  Notice of the sale describes the collateral in general, non-
specific terms;

          (c)  The sale is conducted at a place designated by Coast, with or
without the Collateral being present;

          (d)  The sale commences at any time between 8:00 a.m. and 6:00 p.m.
Los Angeles, California time;

          (e)  Payment of the purchase price in cash or by cashier's check or
wire transfer is required; and

          (f)  With respect to any sale of any of the Collateral, Coast may (but
is not obligated to) direct any prospective purchaser to ascertain directly from
Borrower any and all information concerning the same.

     Coast shall be free to employ other methods of noticing and selling the
Collateral, in its discretion, if they are commercially reasonable.

     10.4 Power of Attorney. Borrower grants to Coast an irrevocable power of
attorney coupled with an interest, authorizing and permitting Coast (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
Coast agrees to exercise the following powers in a commercially reasonable
manner:

          (a)  Execute on behalf of Borrower any documents that Coast may, in
its sole discretion, deem advisable in order to perfect and maintain Coast's
security interest in the Collateral, or in order to exercise a right of Borrower
or Coast, 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
Coast's Collateral or in which Coast 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
Coast's possession;

          (e)  Endorse all checks and other forms of remittances received by
Coast;

          (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 Coast the same rights
of access and other rights with respect thereto as Coast 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 sums paid and any and all costs, expenses, liabilities,
obligations and attorneys' fees incurred by Coast (including attorneys' fees and
expenses incurred pursuant to bankruptcy) with respect to the foregoing shall be
added to and become part of the Obligations, and shall be payable on demand.
Coast may charge the foregoing to Borrower's loan account and the foregoing
shall thereafter bear interest at the same rate applicable to the Receivable
Loans.  In no event shall Coast's rights under the foregoing power of attorney
or any of Coast's other rights under this Agreement be deemed to indicate that
Coast is in control of the business, management or properties of Borrower.
Borrower shall pay, indemnify, defend, and hold Coast and each of its officers,
directors, employees, counsel, agents, and attorneys-in-fact (each, an
"Indemnified Person") harmless (to the fullest extent permitted by law) from and
against any and all claims, demands, suits, actions, investigations,
proceedings, and damages, and all attorneys fees and disbursements and other
costs and expenses actually incurred in connection therewith (as and when they
are incurred and irrespective of whether suit is brought), at any time asserted
against, imposed upon, or incurred by any of them in connection with or as a
result of or related to the execution, delivery, enforcement, performance, and
administration of this Agreement and any other Loan Documents or the
transactions contemplated herein, and with respect to any investigation,
litigation, or proceeding related to this Agreement, any other Loan Document, or
the use of the proceeds of the credit provided hereunder (irrespective of
whether any Indemnified Person is a party thereto), or any act, omission, event
or circumstance in any manner related thereto (all the foregoing, collectively,
the "Indemnified Liabilities").  Borrower shall have no obligation to any
Indemnified Person hereunder with respect to any Indemnified Liability that a
court of competent jurisdiction finally determines to have resulted from the
gross negligence or willful misconduct of such Indemnified Person.  This
provision shall survive the termination of this Agreement and the repayment of
the Obligations.

Coast Business Credit                                Loan and Security Agreement
--------------------------------------------------------------------------------

     10.5 Application of Proceeds. All proceeds realized as the result of any
sale of the Collateral shall be applied by Coast first to the costs, expenses,
liabilities, obligations and attorneys' fees incurred by Coast 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
Coast shall determine in its sole discretion. Any surplus shall be paid to
Borrower or other persons legally entitled thereto; Borrower shall remain liable
to Coast for any deficiency. If, Coast, in its sole discretion, directly or
indirectly enters into a deferred payment or other credit transaction with any
purchaser at any sale of Collateral, Coast 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 Coast of the cash therefor.

     10.6 Remedies Cumulative. In addition to the rights and remedies set forth
in this Agreement, Coast shall have all the other rights and remedies accorded a
secured party in equity, under the Code, and under all other applicable laws,
and under any other instrument or agreement now or in the future entered into
between Coast and Borrower, and all of such rights and remedies are cumulative
and none is exclusive. Exercise or partial exercise by Coast of one or more of
its rights or remedies shall not be deemed an election, nor bar Coast from
subsequent exercise or partial exercise of any other rights or remedies. The
failure or delay of Coast 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 indefeasibly paid and
performed.

11.  GENERAL PROVISIONS.

     11.1 Interest Computation. In computing interest on the Obligations, all
checks, wire transfers and other items of payment received by Coast (including
proceeds of Receivables and payment of the Obligations in full) shall be deemed
applied by Coast on account of the Obligations three (3) Business Days after
receipt by Coast of immediately available funds, and, for purposes of the
foregoing, any such funds received after 10:30 AM Los Angeles, California time,
on any day shall be deemed received on the next Business Day. Coast shall be
entitled to charge Borrower's account for such three (3) Business Days of
"clearance" or "float" at the rate(s) set forth in Section 3 of the Schedule on
all checks, wire transfers and other items received by Coast, regardless of
whether such three (3) Business Days of "clearance" or "float" actually occur,
and shall be deemed to be the equivalent of charging three (3) Business Days of
interest on such collections. This across-the-board three (3) Business Day
clearance or float charge on all collections is acknowledged by the parties to
constitute an integral aspect of the pricing of Coast's financing of Borrower.
Coast shall not, however, be required to credit Borrower's account for the
amount of any item of payment which is unsatisfactory to Coast in its sole
discretion, and Coast may charge Borrower's loan account for the amount of any
item of payment which is returned to Coast unpaid.

     11.2 Application of Payments. Subject to Section 7.5 hereof, all payments
with respect to the Obligations may be applied, and in Coast's sole discretion
reversed and re-applied, to the Obligations, in such order and manner as Coast
shall determine in its sole discretion.

     11.3 Charges to Accounts. Coast may, in its discretion, require that
Borrower pay monetary Obligations in cash to Coast, or charge them to Borrower's
Loan account, in which event they will bear interest from the date due to the
date paid at the same rate applicable to the Loans.

     11.4 Monthly Accountings. Coast 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 Coast), unless Borrower
notifies Coast in writing to the contrary within thirty (30) days after each
account is rendered, describing the nature of any alleged errors or omissions.

     11.5 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, facsimile or certified mail return
receipt requested, addressed to Coast or Borrower at the addresses shown in the
heading to this Agreement, or at any other address designated in writing by one
party to the other party. Notices to Coast shall be directed to the Commercial
Finance Division, to the attention of

                                       18

Coast Business Credit                                Loan and Security Agreement
--------------------------------------------------------------------------------

the Division Manager or the Division Credit Manager. All notices shall be deemed
to have been given upon delivery in the case of notices personally delivered,
faxed (at time of confirmation of transmission), or at the expiration of one (1)
Business Day following delivery to the private delivery service, or two (2)
Business Days following the deposit thereof in the United States mail, with
postage prepaid.

     11.6  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.

     11.7  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 Coast 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.

     11.8  Waivers. The failure of Coast 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 Coast shall not waive or
diminish any right of Coast 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 Coast shall be deemed to have been waived
by any act or knowledge of Coast or its agents or employees, but only by a
specific written waiver signed by an authorized officer of Coast 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 Coast on which
Borrower is or may in any way be liable, and notice of any action taken by
Coast, unless expressly required by this Agreement.

     11.9  No Liability for Ordinary Negligence. Neither Coast, nor any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Coast shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower
or any other party through the ordinary negligence of Coast, or any of its
directors, officers, employees, agents, attorneys or any other Person affiliated
with or representing Coast, but nothing herein shall relieve Coast from
liability for its own gross negligence or willful misconduct.

     11.10 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 Coast.

     11.11 Time of Essence. Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

     11.12 Attorneys' Fees, Costs and Charges. Borrower shall reimburse Coast
for all reasonable attorneys' fees (including attorneys' fees and expenses
incurred pursuant to bankruptcy) and all filing, recording, search, title
insurance, appraisal, audit, and other costs incurred by Coast, pursuant to, or
in connection with, or relating to this Agreement (whether or not a lawsuit is
filed), including, but not limited to, any attorneys' fees and costs (including
attorneys' fees and expenses incurred pursuant to bankruptcy) Coast 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 Coast's
security interest in, the Collateral; and otherwise represent Coast in any
litigation relating to Borrower. If either Coast 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 costs and attorneys' fees
(including

                                       19

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

attorneys' fees and expenses incurred pursuant to bankruptcy), including (but
not limited to) attorneys' fees and costs incurred in the enforcement of,
execution upon or defense of any order, decree, award or judgment. Borrower
shall also pay Coast's standard charges for returned checks and for wire
transfers, in effect from time to time. All attorneys' fees, costs and charges
(including attorneys' fees and expenses incurred pursuant to bankruptcy) and
other fees, costs and charges to which Coast may be entitled pursuant to this
Agreement may be charged by Coast to Borrower's loan account and shall
thereafter bear interest at the same rate as the Receivable Loans.

     11.13  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 Coast; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Coast, and any prohibited
assignment shall be void. No consent by Coast to any assignment shall release
Borrower from its liability for the Obligations. Coast may assign its rights and
delegate its duties hereunder without the consent of Borrower. Coast reserves
the right to syndicate all or a portion of the transaction created herein or
sell, assign, transfer, negotiate, or grant participations in all or any part
of, or any interest in Coast's rights and benefits hereunder. In connection with
any such syndication, assignment or participation, Coast may disclose all
documents and information which Coast now or hereafter may disclose all
documents and information which Coast now or hereafter may have relating to
Borrower or Borrower's business, provided that the recipient of the information
agrees, in writing, to keep such information confidential. To the extent that
Coast assigns its rights and obligations hereunder to a third Person, Coast
thereafter shall be released from such assigned obligations to Borrower to the
extent that such obligations are to be performed after such assignment.

     11.14  Publicity. Subject to Borrower's written consent not to be
unreasonably withheld, Coast is hereby authorized, at its expense, to issue
appropriate press releases and to cause a tombstone to be published announcing
the consummation of this transaction and the aggregate amount thereof.

     11.15  Paragraph Headings; Construction. Paragraph headings are only used
in this Agreement for convenience. Borrower and Coast 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 Coast or Borrower under any rule
of construction or otherwise.

     11.16  Governing Law; Jurisdiction; Venue This Agreement and all acts and
transactions hereunder and all rights and obligations of Coast and Borrower
shall be governed by the internal laws of the State of California, without
regard to its conflicts of law principles. As a material part of the
consideration to Coast to enter into this Agreement, Borrower (a) agrees that
all actions and proceedings relating directly or indirectly to this Agreement
shall, at Coast's option, be litigated in courts located within California, and
that the exclusive venue therefor shall be Los Angeles County; (b) 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 (c) 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.

     11.17  Mutual Waiver of Jury Trial BORROWER AND COAST 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 COAST AND BORROWER, OR ANY CONDUCT, ACTS OR
OMISSIONS OF COAST OR BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES,
AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH COAST OR BORROWER, IN ALL
OF THE FOREGOING CASES, WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE.
