this Agreement.

         "Business Day" means a day on which Coast is open for business.

         "Change of Control" shall be deemed to have occurred at such time as a
"person" or "group" (within the meaning of Sections 13(d) and 14(d)(2) of the
Securities Exchange Act of 1934) (other than the current holders of the
ownership interests in any Borrower) becomes the "beneficial owner" (as defined
in Rule 13d-3 under the Securities Exchange Act of 1934), directly or
indirectly, as a result of any single transaction, of more than twenty percent
(20%) of the total voting power of all classes of stock or other ownership
interests then outstanding of any Borrower normally entitled to vote in the
election of directors or analogous governing body.

         "Closing Date" date of the initial funding under this Agreement.

         "Coast" has the meaning set forth in the introduction to this
Agreement.

         "Code" means the Uniform Commercial Code as adopted and in effect in

<PAGE>


COAST BUSINESS CREDIT                                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

to the amounts and percentages shown on the Schedule.

         "Default" means any event which with notice or passage of time or both,
would constitute an Event of Default.

         "Deposit Account" has the meaning set forth in Section 9105 of the
Code.

         "Dollars or $" means United States dollars.

         "Early Termination Fee" means the amount set forth on the Schedule that
Borrower must pay Coast if this Agreement is terminated by Borrower or Coast
pursuant to Section 9.2 hereof.

         "EBIT" means, in any fiscal period, Borrower's consolidated Net Income
(other than extraordinary or non-recurring items of Borrower for such period),
plus (i) the amount of all interest expense and income tax expense of Borrower
for such period, on a consolidated basis, and plus or minus (as the case may be)
(ii) any other non-cash charges which have been added or subtracted, as the case
may be, in calculating Borrower's consolidated net income for such period.

         "Eligible Foreign Receivables" means Receivables arising from
Borrower's customers located outside the United States which Coast otherwise
approves for borrowing in its sole and absolute discretion. Without limiting the
foregoing, Coast will consider the following in determining the eligibility of
such receivables: (i) whether the Borrower's goods are shipped backed by an
irrevocable letter of credit satisfactory to Coast (as to form, substance, and
issuer or domestic confirming bank) that has been delivered to Coast and is
directly drawable by Coast, or (ii) whether the Borrower's customer is a large
or rated company having a verifiable credit history, or (iii) whether Borrower's
customer is a foreign subsidiary of a customer of Borrower that is a company
that was formed and has its primary place of business within the United States,
or (iv) whether Borrower's customer is a large foreign corporation, or (v)
whether Borrower's customer is a foreign company with a Dun & Bradstreet rating,
or (vi) whether Borrower's goods are shipped to a company that has credit
insurance acceptable to Coast in its discretion. By way of clarification, if
Borrower ships goods to a foreign jurisdiction but the corresponding Receivable
is invoiced to a United States address for the Account Debtor and is in all
other respects an Eligible Receivable, such Eligible Receivable shall be a
standard Eligible Receivable and not a foreign Receivable.

         "Eligible Inventory" means Inventory which Coast, in its sole judgment,
deems eligible for borrowing, based on such considerations as Coast may from
time to time deem appropriate. Without limiting the fact that the determination
of which Inventory is eligible for borrowing is a matter of Coast's discretion,
Inventory which does not meet the following requirements will not be deemed to
be Eligible Inventory: Inventory which (i) consists of finished goods or raw
material less than one year old, in good, new and salable condition which is not
perishable, not obsolete or unmerchantable, and is not comprised of work in
process, subassemblies, packaging materials or supplies; (ii) meets all
applicable governmental standards; (iii) has been manufactured in compliance
with the Fair Labor Standards Act; (iv) conforms in all respects to the
warranties and representations set forth in this Agreement; (v) is at all times
subject to Coast's duly perfected, first priority security interest; (vi) is
situated at a one of the locations set forth on the Schedule; and (vii) has a
recognized market with significant demand.

         "Eligible Receivables" means Borrower's Receivables, Eligible UK
Receivables, and Eligible Foreign Receivables arising in the ordinary course of
Borrower's or Research Limited's business from the sale of goods or rendition of
services, which Coast, in its sole judgment, shall deem eligible for borrowing,
based on such considerations as Coast may from time to time deem appropriate.
Eligible Receivables shall not include the following:

            (a) Receivables that the Account Debtor has failed to pay within 90
days of invoice date;

            (b) Receivables owed by an Account Debtor or its Affiliates where
twenty five percent (25%) or more of all Receivables owed by that Account Debtor
(or its Affiliates) are deemed ineligible under clause (a) above;

            (c) Receivables with respect to which the Account Debtor is an
employee, Affiliate, or agent of Borrower or Research Limited, provided that a
Receivable with respect to which the Account Debtor is an independent sales

representative of Borrower shall not be considered ineligible by reason of this
clause (c);

            (d) Receivables with respect to which goods are placed on

sovereign state, or of any state, province, municipality, or other political
subdivision thereof, or of any department, agency, public corporation, or other
instrumentality thereof;

            (f) Receivables with respect to which the Account Debtor is either

has complied, to the satisfaction of Coast, with the Assignment of Claims Act,
31 U.S.C. " 3727), or (ii) any State of the United States (exclusive, however,

            (g) Receivables with respect to which the Account Debtor is a

has disputed its liability, or has made any claim with respect to the

(25%) of all Eligible Receivables, to the extent of the obligations owing by
such Account Debtor in excess of such percentage;

Receivable have not been shipped and billed to the Account Debtor, the services
giving rise to such Receivable have not been performed and accepted by the
Account Debtor, or the Receivable otherwise does not represent a final sale;

            (l) Receivables with respect to which the Account Debtor is located
in the states of New Jersey, Minnesota, Indiana, or West Virginia (or any other

         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

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 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

Borrower.

         6.9 COMPLIANCE WITH LAW. 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
purchasing or carrying any "margin stock."

         6.12 YEAR 2000 COMPLIANCE. As the result of a comprehensive review and
assessment undertaken by Borrower of Borrower's computer systems, software and
applications and after due inquiry made of Borrower's material suppliers,
vendors and customers, Borrower represents and warrants that Borrower knows of
no facts that would cause Borrower to reasonably believe that the Year 2000
Problem will cause a Material Adverse Effect.

7.       RECEIVABLES.

         7.1 REPRESENTATIONS RELATING TO RECEIVABLES. Borrower represents and
warrants to Coast 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 or Research Limited'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 and Research
Limited'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 and Research Limited'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,

<PAGE>


COAST BUSINESS CREDIT                                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

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 and Research Limited shall have
the right to collect all Receivables, unless and until an Event of Default has
occurred. Borrower and Research Limited 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 or
two (2) Business Days after receipt by Research Limited, 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 or two (2) Business Days after receipt by Research Limited,
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 or Research Limited'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 and if requested by Coast, 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, Research Limited, 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

COAST BUSINESS CREDIT                                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

Limited'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 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
written reports set forth in Section 8 of the Schedule, and such other written
reports with respect to Borrower or Research Limited (including budgets, sales
projections, operating plans and other financial documentation), as Coast shall
from time to 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. Neither Borrower nor
Research Limited will enter into any agreement with any accounting firm, service
bureau or third party to store Borrower's or Research Limited's books or records
at any location other than, respectively, Borrower's or Research Limited's chief
executive office, 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 Research Limited's and its material
accounting and software, systems and applications, and those of its and Research
Limited's 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
transaction in which (i) the owners of the Borrower hold at least fifty percent
(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
payment of an aggregate amount in excess of the amount set forth in Section 8 of
the Schedule;

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

COAST BUSINESS CREDIT                                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

            (d) sell or transfer any Collateral, except for the sale of finished
Inventory in the ordinary course of Borrower's business, and except for the sale
of obsolete or unneeded Equipment in the ordinary course of business;

            (e) store any Inventory or other Collateral with any warehouseman or
other third party unless such party has provided Coast with a waiver in form and
substance satisfactory to Coast in its sole discretion;

            (f) sell any Inventory on a sale-or-return, guaranteed sale,
consignment, or other contingent basis, provided that Borrower may consign
Inventory with an aggregate value of not exceeding $500,000 in the period from
the date hereof through the date 120 days after the Closing Date; and thereafter
not exceeding $200,000 to any one party or $400,000 in the aggregate.

            (g) except as set forth in the Schedule with respect to advances to
Research Limited, make any loans of any money or other assets, except (i)
advances to customers or suppliers in the ordinary course of business, (ii)
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 ownership
interests in Borrower (except for dividends or distributions payable solely in
stock form of ownership interests in Borrower);

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

            (l) dissolve or elect to dissolve.

            Transactions permitted by the foregoing provisions of this Section,
other than the sale of Inventory in the ordinary course of business, 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 or Research Limited, Borrower shall, without expense to Coast, make
available Borrower and Research Limited and their respective officers,
employees, agents, 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.

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.

         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


                                       13

<PAGE>


COAST BUSINESS CREDIT                                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

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.
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 deliver to Borrower termination statements, requests for reconveyances
and such other documents as may be required to fully terminate Coast's security
interests.

10.      EVENTS OF DEFAULT AND REMEDIES

         10.1 EVENTS OF DEFAULT. The occurrence of any of the following events
shall constitute an "Event of Default" under this Agreement, and Borrower shall
give Coast immediate written notice thereof:

            (a) Any warranty, representation, statement, report or certificate
made or delivered to Coast by Borrower, Research Limited, or any of their
respective officers, employees or agents, now or in the future, shall be untrue

            (b) Borrower shall fail to pay when due any Loan or any interest
thereon or any other monetary Obligation; or

            (c) the total Loans and other Obligations outstanding at any time
shall exceed the Credit Limit; or

            (d) Borrower shall fail to deliver the proceeds of Collateral to
Coast as provided in Section 7.5 above, or shall fail to give Coast access to
its or Research Limited's books and records or Collateral as provided in Section
8.4 above, or shall breach any negative covenant set forth in Section 8.5 above;
or

            (e) Borrower shall fail to comply with the financial covenants (if
any) set forth in the Schedule or shall fail to perform any other non-monetary
Obligation which by its nature cannot be cured; or

            (f) Borrower shall fail to perform any other non-monetary
Obligation, which failure is not cured within five (5) Business Days after the
date due; or

            (g) Any levy, assessment, attachment, seizure, lien or encumbrance
(other than a Permitted Lien) is made on all or any part of the Collateral which
is not cured within ten (10) days after the occurrence of the same; or

            (h) any default or event of default occurs under any obligation
secured by a Permitted Lien, which is not cured within any applicable cure
period or waived in writing by the holder of the Permitted Lien; or

            (i) Borrower or Research Limited breaches any material contract or
obligation, which has or may reasonably be expected to have a Material Adverse
Effect; or

            (j) Dissolution, termination of existence, insolvency or business
failure of Borrower or any guarantor of any of the Obligations; or appointment
of a receiver, trustee or custodian, for all or any part of the property of,
assignment for the benefit of creditors by, or the commencement of any

reorganization, bankruptcy, insolvency, arrangement, readjustment of debt,
dissolution or liquidation law or statute of any jurisdiction, now or in the
future in effect; or

guarantor of any of the Obligations under any reorganization, bankruptcy,
insolvency, arrangement, readjustment of debt, dissolution or liquidation law or

any jurisdiction, now or in the future in effect, which is (i) not timely
controverted, or (ii) not cured by the dismissal thereof within thirty (30) days
after the date commenced; or

            (l) revocation or termination of, or limitation or denial of

foregoing, or commencement of proceedings by any guarantor of any of the
Obligations under any bankruptcy or insolvency law; or

            (m) revocation or termination of, or limitation or denial of
liability upon, any pledge of any certificate of deposit, securities or other
property or asset of any kind pledged by any third party to secure any or all of

proceedings by or against any such third party under any bankruptcy or
insolvency law; or

            (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
or experience any Change of Control without Coast's prior written consent, which
consent shall be in the discretion of Coast in the exercise of its reasonable
business judgment; or

            (p) Borrower or Research Limited shall generally not pay its debts
as they become due, or Borrower or Research Limited shall conceal, remove or
transfer any part of its property, with intent to hinder, delay or defraud its
creditors, or make or suffer any transfer of any of its property which may be
fraudulent under any bankruptcy, fraudulent 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

                (iii) any requirement that Coast retain possession of, and not
dispose of, any such Collateral until after trial or final judgment;

            (d) Require Borrower to assemble any or all of the Collateral and
make it available to 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;

COAST BUSINESS CREDIT                                LOAN AND SECURITY AGREEMENT
--------------------------------------------------------------------------------

            (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
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.

         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 or Research Limited, 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 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

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 attorneys' fees (including attorneys' fees and expenses incurred

the prevailing party in such action shall be entitled to recover its costs and
attorneys' fees (including 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

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

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
