                   INTERNATIONAL REMOTE IMAGING SYSTEMS, INC.
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.   Formation and Business of the Company.

     International Remote Imaging Systems, Inc. was incorporated in California
in 1979 and reincorporated during 1987 in Delaware. International Remote Imaging
Systems, Inc. and its subsidiaries (collectively "IRIS" or the "Company")
operate primarily in one segment. The Company designs, develops, manufactures
and markets in vitro diagnostic ("IVD") equipment, including imaging systems
based on patented and proprietary automated intelligent microscopy ("AIM")
technology, and special purpose centrifuges and other small instruments for
specimen preparation in microscopic and other procedures performed in clinical
laboratories. The Company also provides ongoing service and supplies to support
the equipment sold.

2.   Summary of Significant Accounting Policies.

Basis of Presentation of Unaudited Interim Financial Statements:

    In the opinion of management, the accompanying unaudited consolidated
financial statements contain all normal recurring adjustments necessary to
present fairly the financial position of the Company as of March 31, 1998 and
1997 and the results of its operations for the three month periods then ended.
These financial statements should be read in conjunction with the financial
statements and notes included in the Company's latest annual report on Form
10-K. Interim results are not necessarily indicative of results for a full year.

Use of Estimates:

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amount of revenues and expenses during the reporting
periods. Actual results could differ from those estimates.

Principles of Consolidation:

    The consolidated financial statements include the accounts of International
Remote Imaging Systems, Inc. and its wholly-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in the consolidated
financial statements.

Reclassifications:

     Certain reclassifications have been made to the 1997 financial statements
to conform with the 1998 presentation.

3.   Comprehensive Income.

     In January 1998, the Company adopted the provisions of Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" ("FAS
130"). FAS 130 establishes standards for reporting and displaying comprehensive
income and its components (revenues, expenses, gains and losses) in financial
statements. FAS 130 requires that all items that are required to be recognized
under accounting standards as components of comprehensive income be reported in
a financial statement that is displayed with the same prominence as other
financial statements.

     No tax effect has been allocated to the foreign currency translation
adjustment for the periods presented.

     The following is a reconciliation of accumulated other comprehensive income
balance for the three months ended March 31, 1998.

6.   Short Term Borrowings and Notes Payable.

     As of March 31, 1998, the Company's liabilities included $3.1 million
outstanding under a bank term loan. On May 8, 1998, the Company repaid the bank
loan with the proceeds of a new loan facility from Foothill Capital Corporation,
a division of Norwest Bank. The new credit facility consists of a $3.6 million
term loan and a $4.0 million revolving line of credit. Borrowings under the line
of credit are limited to a percentage of eligible accounts receivable and are
subject to a combined limit of $7.0 million for the entire credit facility. The
Company had approximately $2.0 million available under the line of credit at
inception. The term loan bears interest at the lender's prime rate (8.5% on May
8, 1998) plus 3.0% and is payable in 36 equal monthly installments. The
revolving credit line bears interest at the lender's prime rate plus 1.0%. The
new credit facility is subject to minimum interest charges, prepayment penalties
and customary fees, is collateralized by a first priority lien on all assets of
the Company and matures in 2001. It also contains financial covenants based
primarily on tangible net worth and cash flow and imposes restrictions on
acquisitions, capital expenditures and cash dividends. At March 31, 1998, $1.9
million of amounts owed under the bank term loan refinanced on a long-term basis
through the new credit facility was reclassified to long-term debt.

     On March 31, 1998, the Company had outstanding notes payable in the
aggregate amount of $1,042,027 from a repurchase of common stock and warrants
from a joint venture partner in 1996. The notes bear interest at the rate of 8%,
and principal is due in bi-monthly installments of $100,000.

7.   Capital Stock.

Stock Issuances:

     During the three months ended March 31, 1998, the Company (i) issued 10,957
shares of common stock in exchange for $20,957 in cash and services under the
Key Employee Stock Purchase Plan, (ii) issued options to purchase 125,900 shares
of common stock under the Company's stock option plans (10,000 of which are
subject to shareholder approval of a new option plan) and (iii) cancelled
options to purchase 3,600 shares of common stock. No options were exercised
during the period. At March 31, 1998, options to purchase 1,388,600 shares of
common stock were issued and outstanding under the Company's stock options
plans. The outstanding options expire by the end of 2008. The exercise price for
these options ranges from $3.03 to $4.50 per share, for an aggregate exercise
price of approximately $4.5 million. At March 31, 1998, there were 602,900
shares of common stock available for the granting of future options of which
590,000 are subject to shareholder approval of a new stock option plan.

     During the three months ended March 31, 1998, warrants were exercised to
purchase 12,778 shares of common stock for $49,487. Also, warrants to purchase
an additional 75,000 shares of common stock were issued for cash proceeds of
$35,000 and 70,098 stock options outstanding relating to the StatSpin
acquisition expired unexercised.

Warrants:

     At March 31, 1998, the following warrants were outstanding and exercisable:

8.   Commitments and Contingencies.

     In July 1996, the Company acquired Perceptive Scientific Instruments, Inc.
("PSI") from Digital Imaging Technologies, Inc. ("DITI"). As part of the
purchase price, the Company issued to DITI a five-year warrant to purchase
875,000 shares of common stock at $8.00 per share. In August 1997, the Company
filed a demand for arbitration against DITI with the American Arbitration
Association. The Company's demand for arbitration alleges material breaches of
the representations, warranties and covenants in the purchase agreement
governing the PSI acquisition. DITI subsequently filed a counterclaim in the
arbitration proceeding alleging that the Company misrepresented or omitted to
disclose material facts in connection with the PSI acquisition. DITI had
previously requested a reduction in the exercise price of the warrant but
elected to seek unspecified monetary damages in the counterclaim. The parties
are currently engaged in discovery. Although the Company does not presently
anticipate any material adverse effect as a result of this arbitration
proceeding, there can be no assurance that it will not have such an effect on
the Company or result in additional dilution to holders of the Common Stock.

9.   Research and Development Grants and Contracts.

     Reimbursements and direct costs connected with research and development
grants and agreements were as follows:

</TABLE>


     Net costs incurred under research and development grants and contracts have
been included in research and development expense in the statements of
operations.

10.  Unusual Charges.

     The results of operations for the three month period ended March 31, 1998,
include unusual charges totaling $37,666 and are primarily legal expenses
relating to the pending arbitration matter with DITI. The unusual charges in the
comparable period in the prior year totaled $95,129 and are primarily legal
expenses related to a completed arbitration matter.

11.  Income Taxes.

     The income tax provision for the three-month period ended March 31, 1998
was $2,218, as compared to an income tax benefit of $87,829 for the comparable
period in the prior year. The income tax provision and benefit for the three
month periods ended March 31, 1998 and 1997, respectively, differs from the
federal statutory rate due to state, local and foreign income taxes and
permanent differences between income reported for financial statement and income
tax purposes.

12.  Earnings Per Share.

     The computation of per share amounts for the three months ended March 31,
1997 is based on the average number of common shares outstanding for the
period. Options and warrants to purchase 2,809,270 shares of common stock
outstanding during the three months ended March 31, 1997 were not considered in
the computation of diluted EPS because their inclusion would have been
antidilutive. Preferred stock convertible into 842,697 common shares at March
31, 1997 was also not considered in the computation of diluted EPS because its
inclusion would have been antidilutive.

     In early 1997 the staff of the Securities and Exchange Commission ("staff")
announced a new position on accounting for convertible preferred stock which is
potentially convertible at a discount to the market price of the common stock,
even if the potential for a discount is only a possibility. The staff has taken
the position, that solely for purposes of calculating earnings per share the
potential discount is an imputed dividend to the preferred stockholders, which
reduces the amount of earnings available to common stockholders. Accordingly,
the issuance of the Series A Preferred Stock resulted in a one-time reduction in
earnings available to common shareholders of $450,000 or $0.08 per share in the
three-month period ended March 31, 1997.

     Options and warrants to purchase 1,783,133 shares of common stock at $4.00

greater than the average market price of the common shares during the period.

13.  Recently Issued Accounting Standards.

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("FAS 131"). This statement requires that a
public business enterprise report financial and descriptive information about
its reportable operating segments. Generally, financial information is required
to be reported on the basis that it is used internally for evaluating segment
performance and deciding how to allocate resources to segments. It is effective
for fiscal years beginning after December 15, 1997. The Company intends to adopt
this new standard in fiscal year 1998, and does not believe that this statement
will have a significant impact on its financial statements.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

OVERVIEW

     The Company generates revenues from sales of in vitro diagnostic ("IVD")
imaging systems based on its patented and proprietary AIM technology. Following
their initial sale, these systems become part of the "installed base" and
generate follow-on sales of supplies and service necessary for their operation.
The Company also generates revenues from sales of ancillary lines of small
laboratory instruments and supplies.

     Until 1996, the Company generated most of its revenues from sales of two
models of The Yellow IRIS urinalysis workstation and related supplies and
service. These two models differ mainly by their speed and price. In 1996, the
Company introduced a third model of The Yellow IRIS, the Model 900UDx urine
pathology system, which is a higher capacity automated urinalysis workstation
designed especially for the high-volume testing requirements of large hospitals
and reference laboratories. The Company also began selling the PowerGene family
of genetic analyzers in August 1996 after completing the acquisition (the "PSI
acquisition") of the digital imaging business of Perceptive Scientific
Instruments, Inc. ("PSI"). Finally, in December 1997, the Company began
distributing the UF-100 urine cell analyzer in the United States under an
existing agreement with its manufacturer, TOA Medical Electronics, Inc.

     The Company invests significant amounts in research and development for new
products and enhancements to existing products. The following table summarizes
total product technology expenditures for the periods indicated:

RESULTS OF OPERATIONS

     Comparison of Quarter Ended March 31, 1998 to Quarter Ended March 31, 1997

     Net revenues for the quarter ended March 31, 1998 increased to $6.6 million
from $6.3 million, an increase of $303,000 or 5% over the comparable period in
the prior year. Sales of IVD imaging systems decreased to $2.4 million from $2.5
million, a decrease of $33,000 or 1% from the comparable period in the prior
year. Revenues from sales of the Yellow IRIS family of urinalysis workstation
decreased slightly due to a shift in sales mix to lower priced units. This
decrease was partially offset by an increase in sales of the PowerGene line of
genetic analyzers.

     Sales of IVD imaging system supplies and services increased to $3.0 million
from $2.6 million, an increase of $349,000 or 13% over the comparable period in
the prior year, primarily due to the larger installed base of The Yellow IRIS
IVD imaging systems. Sales of small instruments and supplies totaled $1.1
million, which is comparable to the prior year.

     Cost of goods for IVD imaging systems increased as a percentage of sales of
IVD imaging systems to 52% for the quarter ended March 31, 1998 from 50% for the
comparable period in the prior year. The increase is primarily due to lower
average selling prices of The Yellow IRIS urinalysis workstations. Cost of goods
for IVD imaging system supplies and services as a percentage of sales of such
products decreased to 45% for the current period as compared to 52% for the same
period in the prior year. The decrease is primarily due to decreased costs and
increased selling prices. Cost of goods for small instruments and supplies as a
percentage of sales of small instruments and supplies totaled 57% for the
current quarter compared to 52% for the comparable period in the prior year. The
increase is primarily due to a change in the sales mix. The net result of these
changes was an increase in aggregate gross margin to 51% for the quarter ended
March 31, 1998, as compared to 50% in the comparable period in the prior year.

     Marketing and selling expenses totaled $1.3 million for the quarter ended
March 31, 1998, which is comparable to the prior year. Marketing and selling
expenses as a percentage of net revenues decreased to 19% in the current quarter
as compared to 20% in the same period in the prior year.

     General and administrative expenses decreased to $818,000 for the quarter
ended March 31, 1998 from $998,000, a decrease of $180,000 or 18% from the
comparable period in the prior year. This decrease is mainly the result of the
reduced expenses resulting from the restructuring implemented in the fourth
quarter of 1996, as well as decreased legal and accounting expenses. General and
administrative expenses as a percentage of net revenues decreased from 16% to
12%. The Company does not anticipate further reduction in the amount of these
expenses, although they may decline as a percentage of net revenues.

     Net research and development expenses increased to $654,000 for the quarter
ended March 31, 1998 from $456,000, an increase of $198,000 or 43% over the
comparable period in the prior year. Net research and development expenses
increased as a percentage of revenues from 7% to 10%. Reimbursements under joint
development programs decreased to $206,000 from $313,000. Total product
technology expenditures, including capitalized software development costs and
reimbursed costs under research and development grants and contracts, increased
to $955,000 from $894,000, an increase of $61,000 or 7% as compared to the
comparable period in the prior year. The increase in total product technology
expenditures is due to increased expenditures relating to the PowerGene family
of genetic analyzers, partially offset by decreased expenditures on products
under a joint development program with Poly UA Systems, Inc., a company
sponsored research and development entity, for several new urinalysis automation
products.

     Amortization of intangible assets for the quarter ended March 31, 1998
decreased to $289,000 from $312,000, a decrease of $23,000 or 7% from the
comparable period in the prior year. The decline is primarily the result of the
write-off in the fourth quarter of 1997 of goodwill from the acquisition of the
digital refractometer product line in 1995.

     The results of operations for the quarter ended March 31, 1998 include
unusual legal expenses of $38,000 relating to a pending arbitration matter. The
unusual legal expenses in the comparable period in the prior year totaled
$95,000 and relate primarily to a separate, completed arbitration matter.

     Interest expense decreased to $271,000 for the quarter ended March 31, 1998
from $311,000 for the comparable period in the prior year due to reduced
indebtedness.

     The income tax provision for the quarter ended March 31, 1998 was $2,000,
as compared to an income tax benefit of $88,000 for the comparable period
in 1997.

     The above factors contributed to a net income of $4,000 or $0.00 per share
for the quarter ended March 31, 1998 as compared to a net loss of $202,000 or
$0.11 per share for the quarter ended March 31, 1997. In early 1997 the staff of
the Securities and Exchange Commission ("staff") announced a new position on
accounting for convertible preferred stock which is potentially convertible at a
discount to the market price of the common stock, even if the potential for a
discount is only a possibility. The staff has taken the position, that solely
for purposes of calculating earnings per share the potential discount is an
imputed dividend to the preferred stockholders, which reduces the amount of
earnings available to common stockholders. Accordingly, the issuance of the
Series A Preferred Stock resulted in a one-time reduction in earnings available
to common shareholders of $450,000 or $0.08 per share in the three-month period
ended March 31, 1997.

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents increased to $1.8 million at March 31, 1998 from
$1.5 million at December 31, 1997. The increase is primarily attributable to
cash provided by operating activities. Due primarily to improved results of
operations in the 1998 period and significant reductions in accounts payable
balances during the 1997 period, cash provided by operations for the three
months ended March 31, 1998 increased to $1.2 million from $164,000 for the
comparable period in the prior year.

     Expenditures for property and equipment and capitalized software
development totaled $153,000 and $95,000, respectively in the current quarter as
compared to $37,000 and $125,000, respectively, in the same quarter in the prior
year. The Company expects greater levels of such expenditures will be required
during the remainder of 1998.

     Net cash used by financing activities totaled $644,000 and consisted
primarily of principal payments under a bank credit facility that matured during
the second quarter of 1998. The bank credit facility consisted of a $7.8 million
term loan and a $1.5 million revolving credit line. As of March 31, 1998, the
Company had $3.1 million outstanding under the bank term loan and had repaid the
revolving credit line.

     On May 8, 1998, the Company terminated the bank credit facility and repaid
the term loan with the proceeds of a new credit facility from Foothill Capital
Corporation, a division of Norwest Bank. The new credit facility consists of a
$3.6 million term loan and a $4.0 million revolving line of credit. Borrowings
under the line of credit are limited to a percentage of eligible accounts
receivable and subject to a combined limit of $7.0 million for the entire credit
facility. The Company had $2.0 million available under the line of credit at
inception. The term loan bears interest at the lender's prime rate (8.5% on
May 8, 1998) plus 3.0% and is payable in 36 equal monthly installments. The
revolving line of credit bears interest at the lender's prime rate plus 1.0%.
The new credit facility is subject to minimum interest charges, prepayment
penalties and customary fees, is collateralized by a first priority lien on all
the assets of the Company and matures in 2001. It also contains financial
covenants based primarily on tangible net worth and cash flow and imposes
restrictions on acquisitions, capital expenditures and cash dividends.

     As of March 31, 1998, the Company also had outstanding notes payable in the
aggregate amount of $1.0 million from the repurchase of common stock and
warrants from a joint venture partner in 1996. The notes bear interest at the
rate of 8.0%, and principal is due in bi-monthly installments of $100,000.

     The Company has scheduled principal payments on outstanding debt totaling
$1.8 million during the next twelve months.

     The Company believes that its current cash on hand, together with cash
generated from operations, and cash available under the new credit facility will
be sufficient to fund normal operations and pay principal and interest on
outstanding debt obligations for the next twelve months.

     The Company plans to pursue equity financing to reduce indebtedness and to
fund its long-term business strategy. While the FDA cleared The White IRIS
leukocyte differential analyzer in May 1996, its commercial release was
temporarily delayed by other priorities such as the introduction of the UF-100
urine sediment analyzer. The Company is now in discussion with two prestigious
medical institutions to serve as testimonial sites for The White IRIS. The
Company's immediate goal is to install the first two commercial systems at these
institutions. By doing so, the Company hopes to develop the customer references
which are a key step toward commercial success of any new major instrument in
the laboratory medicine business. Expanded commercial release of The White IRIS
may depend upon the availability of sufficient funds and may be subject to
additional delays if such funds are unavailable.

     In September 1995, the Company and Poly U/A Systems Inc. ("Poly") entered
into a research and development agreement to develop several new urinalysis
automation products using the Company's technology. The Company is funding the
first $15,000 per month of the cost of the project (up to a maximum of $500,000,
of which $35,000 remains unexpended), and Poly is reimbursing the Company for
the excess. The Company has an option until November 29, 1998 to acquire all of
the common stock of Poly for an aggregate price of $5.1 million, payable in cash
or shares of Common Stock of the Company. If the Company elects to exercise its
option, the portion of the net cost of the acquisition allocated to completed
products would be capitalized and its subsequent amortization may impact future
earnings to the extent profits from products acquired do not cover these costs.
For the portion of the net cost of the acquisition allocated to in-process
research and development, if any, the Company would record a nonrecurring,
noncash (if purchased with Common Stock) charge against then current earnings.

INFLATION

     The Company does not foresee any material impact on its operations from
inflation.

HEALTHCARE REFORM POLICIES

     In recent years, an increasing number of legislative proposals have been
introduced or proposed in Congress and in some state legislatures that would
effect major changes in the healthcare system, nationally, at the state level or
both. Future legislation, regulation or payment policies of Medicare, Medicaid,
private health insurance plans, health maintenance organizations and other
third-party payors could adversely affect the demand for the Company's current
or future products and its ability to sell its products on a profitable basis.
Moreover, healthcare legislation is an area of extensive and dynamic change, and
the Company cannot predict future legislative changes in the healthcare field or
their impact on its business.

RECENTLY-ISSUED ACCOUNTING STANDARDS

     Recently issued accounting standards are described in Note 13 to the
financial statements.

FORWARD-LOOKING STATEMENTS

     The foregoing discussion contains various forward-looking statements which
reflect the Company's current views with respect to future events and financial
results and are subject to the safe harbor provisions of the Private Securities
Litigation Reform Act of 1995. These forward-looking statements include, but are
not limited to, the Company's views with respect to future financial results,
capital requirements, market growth, new product introductions and the like, and
are generally identified by phrases such as "anticipates," "believes,"
"estimates," "expects," "intends," "plans" and words of similar import. The
Company reminds stockholders that forward-looking statements are merely
predictions and therefore inherently subject to uncertainties and other factors
which could cause the actual results to differ materially from the
forward-looking statement. The Company has attempted to identify some of these
uncertainties and other factors in its 1997 Annual Report on Form 10-K.


PART 2 - OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS.

     In July 1996, the Company acquired PSI from Digital Imaging Technologies,
Inc. ("DITI"). As part of the purchase price, the Company issued to DITI a
five-year warrant to purchase 875,000 shares of Common stock at $8.00 per share.
In August 1997, the Company filed a demand for arbitration against DITI with the
American Arbitration Association. The Company's demand for arbitration alleges
material breaches of the representations, warranties and covenants in the
purchase agreement governing the PSI acquisition. DITI subsequently filed a
counterclaim in the arbitration proceeding alleging that the Company
misrepresented or omitted to disclose material facts in connection with the PSI
acquisition. DITI had previously requested a reduction in the exercise price of
the warrant but elected to seek unspecified monetary damages in the
counterclaim. The parties are currently conducting discovery. Although the
Company does not presently anticipate any material adverse effect as a result of
this arbitration proceeding, there can be no assurance that it will not have
such an effect on the Company or result in additional dilution to holders of the
Common Stock.

     The Company is involved in routine litigation arising in the ordinary
course of its business, and, while the results of the proceedings cannot be
predicted with certainty, the Company believes that the final outcome of such
matters will not have a material adverse effect on the Company.

         2.      LOAN AND TERMS OF PAYMENT.

                 2.1      REVOLVING ADVANCES.

                          (a)     Subject to the terms and conditions of this
Agreement, Foothill agrees to make advances ("Advances") to Borrowers in an
amount outstanding not to exceed at any one time the lesser of (i) the Maximum
Revolving Amount or (ii) the Borrowing Base.  For purposes of this Agreement,
"Borrowing Base", as of any date of determination, shall mean the result of:

                                  (x)      85% of Eligible Accounts, less the
                 amount, if any, of the Dilution Reserve and Installation
                 Reserve, minus

                                  (z)      the aggregate amount of reserves, if
                 any, established by Foothill under Sections 2.1(b), 6.15 and 
                 10.

                          (b)     Anything to the contrary in Section 2.1(a)
above notwithstanding, Foothill may create reserves against the Borrowing Base
or reduce its advance rates based upon Eligible Accounts without declaring an
Event of Default if it determines that there has occurred a Material Adverse
Change.

                          (c)     Anything to the contrary in this Agreement
notwithstanding, the aggregate outstanding balance of the Advances and the Term
Loan shall not exceed an amount equal to Borrowers' Collections with respect to
Accounts for the immediately preceding 90 day period.

                          (d)     Amounts borrowed pursuant to this Section 2.1
may be repaid and, subject to the terms and conditions of this Agreement,
reborrowed at any time during the term of this Agreement.

                 2.2      INTENTIONALLY OMITTED.

                 2.3      TERM LOAN.  Foothill has agreed to make a term loan
(the "Term Loan") to Borrowers in the original principal amount of $3,600,000.
The Term Loan shall be repaid in 36 installments of principal in the following
amounts:


<TABLE>
<CAPTION>
   MONTH                                        INSTALLMENT AMOUNT

1 through 36                                        $100,000
</TABLE>

Each such installment shall be due and payable on the first day of each month
commencing on the first day of the first month following the Closing Date and
continuing on the first day of each succeeding month until and including the
date on which the unpaid balance of the





                                       15
<PAGE>   21
Term Loan is paid in full.  Borrowers shall not prepay the Term Loan except in
accordance with Section 3.6 or 2.5.  The outstanding principal balance and all
accrued and unpaid interest under the Term Loan shall be due and payable upon
the termination of this Agreement, whether by its terms, by prepayment, by
acceleration, or otherwise.  All amounts outstanding under the Term Loan shall
constitute Obligations.

                 2.4      INTENTIONALLY OMITTED.

                 2.5      OVERADVANCES; LOAN MAXIMUMS.

                          (a)     If, at any time or for any reason, the amount
of Obligations owed by Borrowers to Foothill pursuant to Section 2.1 is greater
than either the Dollar or percentage limitations set forth in Section 2.1 (an
"Overadvance"), Borrowers immediately upon demand shall pay to Foothill, in
cash, the amount of such excess to be used by Foothill to repay Advances
outstanding under Section 2.1.

                          (b)     If, at any time or for any reason, the amount
of Obligations owed by Borrowers to Foothill pursuant to Section 2.1 plus the
principal balance of the Term Loan is greater than an amount equal to:  (i) the
result of multiplying (a) Borrowers' annualized Supply and Service Revenue
based on the most recent fiscal quarter, by (b) the percentage indicated in the
table below opposite the applicable period, less (ii) the amount of IRIS'
warranty reserve:

<TABLE>
<CAPTION>
                 Period                                     Percentage
                 -----------------------------------------------------
                 <S>                                       <C>
                 Closing Date - March 31, 1999              80%
                 April 1, 1999 - March 31, 2000             70%
                 April 1, 2000 and thereafter               60%
</TABLE>

then, Borrowers immediately shall pay to Foothill, in cash, the amount of such
excess to be used by Foothill to first repay Advances outstanding under Section
2.1, and second toward principal installments due under the Term Loan in
inverse order of maturity without penalty.

                          (c)     If, at any time or for any reason, the
principal balance of the Term Loan is greater than an amount equal to: (i) the
result of multiplying (a) Borrowers' annualized Supply and Service Revenue
based on the most recent fiscal quarter, by (b) by the percentage indicated in
the table below opposite the applicable period, less (ii) the amount of IRIS'
warranty reserve:

then, Borrowers immediately shall pay to Foothill, in cash, the amount of such
excess to be used by Foothill toward principal installments due under the Term
Loan in inverse order of maturity without penalty.

                 2.6      INTEREST:  RATES, PAYMENTS, AND CALCULATIONS.

                          (a)     Interest Rate.  Except as provided in clause
(b) below, (i) all Obligations (except for the Term Loan) shall bear interest
on the Daily Balance at a per annum rate of one percentage point above the
Reference Rate, and (ii) the Term Loan shall bear interest at a per annum rate
of three percentage points above the Reference Rate.

                          (b)     Default Rate.  Upon the occurrence and during
the continuation of an Event of Default, (i) all Obligations (except for the
Term Loan) shall bear interest at a per annum rate equal to five percentage
points above the Reference Rate, and (ii) the Term Loan shall bear interest at
a per annum rate equal to seven percentage points above the Reference Rate.

                          (c)     Minimum Interest.  In no event shall the rate
of interest chargeable hereunder for any day be less than 7.00% per annum.
Additionally, in no event shall the interest due hereunder in any month be less
than what would be due based on average daily outstanding Obligations of
$3,000,000.  To the extent that interest accrued hereunder at the rate set
forth herein would be less than the foregoing minimum daily rate, the interest
rate chargeable hereunder for such day automatically shall be deemed increased
to the minimum rate.

                          (d)     Payments.  Interest payable hereunder shall
be due and payable, in arrears, on the first day of each month during the term
hereof.  Each Borrower hereby authorizes Foothill, at its option, without prior
notice to such Borrower, to charge such interest, all Foothill Expenses (as and
when incurred), the fees and charges provided for in Section 2.11 (as and when
accrued or incurred), and all installments or other payments due under the Term
Loan or any Loan Document to Borrowers' Loan Account, which amounts thereafter
shall accrue interest at the rate then applicable to Advances hereunder.  Any
interest not paid when due shall be compounded and shall thereafter accrue
interest at the rate then applicable to Advances hereunder.

                          (e)     Computation.  The Reference Rate as of the
date of this Agreement is 8.50% per annum.  In the event the Reference Rate is
changed from time to time hereafter, the applicable rate of interest hereunder
automatically and immediately shall be increased or decreased by an amount
equal to such change in the Reference Rate.  All interest and fees chargeable
under the Loan Documents shall be computed on the basis of a 360 day year for
the actual number of days elapsed.

                          (f)     Intent to Limit Charges to Maximum Lawful
Rate.  In no event shall the interest rate or rates payable under this
Agreement, plus any other amounts paid in





                                       17
<PAGE>   23
connection herewith, exceed the highest rate permissible under any law that a
court of competent jurisdiction shall, in a final determination, deem
applicable.  Borrowers and Foothill, in executing and delivering this
Agreement, intend legally to agree upon the rate or rates of interest and
manner of payment stated within it; provided, however, that, anything contained
herein to the contrary notwithstanding, if said rate or rates of interest or
manner of payment exceeds the maximum allowable under applicable law, then,
ipso facto as of the date of this Agreement, Borrowers are and shall be liable
only for the payment of such maximum as allowed by law, and payment received
from Borrowers in excess of such legal maximum, whenever received, shall be
applied to reduce the principal balance of the Obligations to the extent of
such excess.

                 2.7      COLLECTION OF ACCOUNTS.  Borrowers shall at all times
maintain lockboxes (the "Lockboxes") and, immediately after the Closing Date,
shall instruct all Account Debtors with respect to the Accounts, General
Intangibles, and Negotiable Collateral of Borrowers to remit all Collections in
respect thereof to such Lockboxes.  Borrowers, Foothill, and the Lockbox Banks
shall enter into the Lockbox Agreements, which among other things shall provide
for the opening of a Lockbox Account for the deposit of Collections at a
Lockbox Bank.  Each Borrower agrees that all Collections and other amounts
received by such Borrower from any Account Debtor or any other source
immediately upon receipt shall be deposited into a Lockbox Account.  No Lockbox
Agreement or arrangement contemplated thereby shall be modified by a Borrower
without the prior written consent of Foothill.  Upon the terms and subject to
the conditions set forth in the Lockbox Agreements, all amounts received in
each Lockbox Account shall be wired each Business Day into an account (the
"Foothill Account") maintained by Foothill at a depositary selected by
Foothill.

                 2.8      CREDITING PAYMENTS; APPLICATION OF COLLECTIONS.  The
receipt of any Collections by Foothill (whether from transfers to Foothill by
the Lockbox Banks pursuant to the Lockbox Agreements or otherwise) immediately
shall be applied provisionally to reduce the Obligations outstanding under
Section 2.1, but shall not be considered a payment on account unless such
Collection item is a wire transfer of immediately available federal funds and
is made to the Foothill Account or unless and until such Collection item is
honored when presented for payment.  From and after the Closing Date, Foothill
shall be entitled to charge Borrowers for two Business Days of `clearance' or
`float' at the rate set forth in Section 2.6(a)(i) or Section 2.6(b)(i), as
applicable, on all Collections that are received by Foothill (regardless of
whether forwarded by the Lockbox Banks to Foothill, whether provisionally
applied to reduce the Obligations under Section 2.1, or otherwise).  This
across-the-board two Business Day clearance or float charge on all Collections
is acknowledged by the parties to constitute an integral aspect of the pricing
of Foothill's financing of Borrowers, and shall apply irrespective of the
characterization of whether receipts are owned by a Borrower or Foothill, and
whether or not there are any outstanding Advances, the effect of such clearance
or float charge being the equivalent of charging two Business Days of interest
on such Collections.  Should any Collection item not be honored when presented
for payment, then Borrowers shall be deemed not to have made such payment, and
interest shall be recalculated accordingly.  Anything to the contrary contained
herein notwithstanding, any





                                       18
<PAGE>   24
Collection item shall be deemed received by Foothill only if it is received
into the Foothill Account on a Business Day on or before 11:00 a.m.  California
time.  If any Collection item is received into the Foothill Account on a
non-Business Day or after 11:00 a.m. California time on a Business Day, it
shall be deemed to have been received by Foothill as of the opening of business
on the immediately following Business Day.  In the event that Borrowers' Loan
Account has a credit balance, Foothill shall, on each Business Day,
automatically transfer such credit balance to Borrowers' Designated Account so
long as no Event of Default has occurred and is continuing.

                 2.9      DESIGNATED ACCOUNT.  Foothill is authorized to make
the Advances and the Term Loan, under this Agreement based upon telephonic or
other instructions received from anyone purporting to be an Authorized Person,
or without instructions if pursuant to Section 2.6(d).  Borrowers agree to
establish and maintain a single Designated Account with the Designated Account
Bank for the purpose of receiving the proceeds of the Advances requested by
Borrowers and made by Foothill hereunder.  Unless otherwise agreed by Foothill
and Borrowers, any Advance requested by Borrowers and made by Foothill
hereunder shall be made to the Designated Account.

                 2.10     MAINTENANCE OF LOAN ACCOUNT; STATEMENTS OF
OBLIGATIONS.  At the request of Borrowers, to facilitate and expedite the
administration and accounting processes and procedures of their borrowings
under this Agreement, Foothill has agreed, in lieu of maintaining separate loan
accounts on Foothill's books in the name of each of the Borrowers, that
Foothill shall maintain a single account on its books in the names of all of
the Borrowers (the "Loan Account").  All Advances and the Term Loan made by
Foothill to Borrowers or for Borrower's account, including accrued interest,
Foothill Expenses, and any other payment Obligations of Borrowers shall be made
jointly and severally to the Borrowers and shall be charged to the Loan
Account.  In accordance with Section 2.8, the Loan Account will be credited
with all payments received by Foothill from any Borrower or for any Borrowers'
account, including all amounts received in the Foothill Account from any
Lockbox Bank.  Each month Foothill shall render one statement regarding the
Loan Account to IRIS on behalf of Borrowers, including principal, interest,
fees, and including an itemization of all charges and expenses constituting
Foothill Expenses owing, and such statements shall be conclusively presumed to
be correct and accurate and constitute an account stated between Borrowers and
Foothill unless, within 30 days after receipt thereof by Borrowers, Borrowers
shall deliver to Foothill written objection thereto describing the error or
errors contained in any such statements.  Each Borrower hereby expressly agrees
and acknowledges that Foothill shall have no obligation to account separately
to such Borrower.

                 2.11     FEES.  Borrowers shall pay to Foothill the following
fees:

                          (a)     Commitment Fee.  A commitment fee in the
amount of $52,500 which has already been paid by Borrowers;





                                       19
<PAGE>   25
                          (b)     Unused Line Fee.  On the first day of each
month during the term of this Agreement, an unused line fee in an amount equal
to 0.375% per annum times the Average Unused Portion of the Maximum Amount.

                          (c)     Financial Examination, Documentation, and
Appraisal Fees.  Foothill's customary fee of $650 per day per examiner, plus
out-of-pocket expenses for each financial analysis and examination (i.e.,
audits) of Borrowers performed by personnel employed by Foothill; provided,
however, that prior to the occurrence of an Event of Default, Borrowers shall
not be responsible for paying for more than four audits conducted by Foothill
in any 12 month period; and the actual charges paid or incurred by Foothill if
it elects to employ the services of one or more third Persons to perform such
financial analyses and examinations (i.e., audits) of Borrowers or to appraise
the Collateral; and

                          (d)     Servicing Fee.  On the first day of each
month during the term of this Agreement, and thereafter so long as any
Obligations are outstanding, a servicing fee in an amount equal to $3,000.

         3.      CONDITIONS; TERM OF AGREEMENT.

                 3.1      CONDITIONS PRECEDENT TO THE INITIAL ADVANCE AND THE

<PAGE>   28
                          (b)     PSI's Accounts shall not be included in
Eligible Accounts until such time as Foothill has: (i) completed a financial
analysis and examination of PSI, and (ii) Foothill's credit committee has
approved the inclusion of such Accounts and the terms and conditions thereof.
Foothill shall use its best efforts to satisfy the conditions set forth in the
preceding sentence within 60 days of the date hereof.

                 3.4      TERM; AUTOMATIC RENEWAL.  This Agreement shall become
effective upon the execution and delivery hereof by Borrowers and Foothill and
shall continue in full force and effect for a term ending on the date (the
"Renewal Date") that is three years from the Closing Date and automatically
shall be renewed for successive one year periods thereafter, unless sooner
terminated pursuant to the terms hereof.  Either party may terminate this
Agreement effective on the Renewal Date or on any one year anniversary of the
Renewal Date by giving the other party at least 90 days prior written notice.
The foregoing notwithstanding, Foothill shall have the right to terminate its
obligations under this Agreement immediately and without notice upon the
occurrence and during the continuation of an Event of Default.

                 3.5      EFFECT OF TERMINATION.  On the date of termination of
this Agreement, all Obligations immediately shall become due and payable
without notice or demand.  No termination of this Agreement, however, shall
relieve or discharge Borrowers of Borrowers' duties, Obligations, or covenants
hereunder, and Foothill's continuing security interests in the Collateral shall
remain in effect until all Obligations have been fully and finally discharged
and Foothill's obligation to provide additional credit hereunder is terminated.
If Borrowers have sent a notice of termination pursuant to the provisions of
Section 3.4, but fail to pay the Obligations in full on the date set forth in
said notice, then Foothill may, but shall not be required to, renew this
Agreement for an additional term of one year.

                 3.6      EARLY TERMINATION BY BORROWERS.  The provisions of
Section 3.4 that allow termination of this Agreement by Borrowers only on the
Renewal Date and certain anniversaries thereof notwithstanding, Borrowers have
the option, at any time upon 45 days prior written notice to Foothill, to
terminate this Agreement by paying to Foothill, in cash, the Obligations, in
full, together with a premium (the "Early Termination Premium") equal to the
amount of the following, as applicable:  (a) 3.00% of the Maximum Amount if
such termination occurs during the first year after the Closing Date, (b) 2.00%
of the Maximum Amount if such termination occurs during the second year after
the Closing Date, and (c) 1.00% of the Maximum Amount if such termination
occurs during the third year after the Closing Date.

                 3.7      TERMINATION UPON EVENT OF DEFAULT.  If Foothill
terminates this Agreement upon the occurrence of an Event of Default, in view
of the impracticability and extreme difficulty of ascertaining actual damages
and by mutual agreement of the parties as to a reasonable calculation of
Foothill's lost profits as a result thereof, Borrowers shall pay to Foothill
upon the effective date of such termination, a premium in an amount equal to
the Early Termination Premium.  The Early Termination Premium shall be presumed
to be the





                                       23
<PAGE>   29
amount of damages sustained by Foothill as the result of the early termination
and Borrowers agree that it is reasonable under the circumstances currently
existing.  The Early Termination Premium provided for in this Section 3.7 shall
be deemed included in the Obligations.

         4.      CREATION OF SECURITY INTEREST.

                 4.1      GRANT OF SECURITY INTEREST.  Each Borrower hereby
grants to Foothill a continuing security interest in all of such Borrower's
currently existing and hereafter acquired or arising Collateral in order to
secure prompt repayment of any and all Obligations and in order to secure
prompt performance by such Borrower of each of its covenants and duties under
the Loan Documents.  Foothill's security interests in the Collateral shall
attach to all Collateral without further act on the part of Foothill or
Borrowers.  Anything contained in this Agreement or any other Loan Document to
the contrary notwithstanding, except for the sale of Inventory to buyers in the
ordinary course of business or as otherwise permitted in Section 7.4, no
Borrower has any authority, express or implied, to dispose of any item or
portion of the Collateral.

                 4.2      NEGOTIABLE COLLATERAL.  In the event that any
Collateral, including proceeds, is evidenced by or consists of Negotiable
Collateral, Borrowers, immediately upon the request of Foothill, shall endorse
and deliver physical possession of such Negotiable Collateral to Foothill.

                 4.3      COLLECTION OF ACCOUNTS, GENERAL INTANGIBLES, AND
NEGOTIABLE COLLATERAL.  At any time that an Event of Default has occurred and
is continuing or Foothill deems itself insecure, Foothill or Foothill's
designee may (a) notify customers or Account Debtors of any Borrower that the
Accounts, General Intangibles, or Negotiable Collateral of such Borrower have
been assigned to Foothill or that Foothill has a security interest therein, and
(b) collect the Accounts, General Intangibles, and Negotiable Collateral of
such Borrower directly and charge the collection costs and expenses to the Loan
Account.  Each Borrower agrees that it will hold in trust for Foothill, as
Foothill's trustee, any Collections that it receives and immediately will
deliver said Collections to Foothill in their original form as received by
Borrower.

                 4.4      DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED.  At
any time upon the request of Foothill, Borrowers shall execute and deliver to
Foothill all financing statements, continuation financing statements, fixture
filings, security agreements, pledges, assignments, endorsements of
certificates of title, applications for title, affidavits, reports, notices,
schedules of accounts, letters of authority, and all other documents that
Foothill reasonably may request, in form satisfactory to Foothill, to perfect
and continue perfected Foothill's security interests in the Collateral, and in
order to fully consummate all of the transactions contemplated hereby and under
the other the Loan Documents.

                 4.5      POWER OF ATTORNEY.  Each Borrower hereby irrevocably
makes, constitutes, and appoints Foothill (and any of Foothill's officers,
employees, or agents





                                       24
<PAGE>   30
designated by Foothill) as such Borrower's true and lawful attorney, with power
to (a) if such Borrower refuses to, or fails timely to execute and deliver any
of the documents described in Section 4.4, sign the name of such Borrower on
any of the documents described in Section 4.4, (b) at any time that an Event of
Default has occurred and is continuing, or Foothill deems itself insecure, sign
such Borrower's name on any invoice or bill of lading relating to any Account
of such Borrower, drafts against Account Debtors, schedules and assignments of
Accounts of such Borrower, verifications of Accounts of such Borrower, and
notices to Account Debtors, (c) send requests for verification of Accounts of
such Borrower, (d) endorse such Borrower's name on any Collection item that may
come into Foothill's possession, (e) at any time that an Event of Default has
occurred and is continuing, notify the post office authorities to change the
address for delivery of such Borrower's mail to an address designated by
Foothill, to receive and open all mail addressed to such Borrower, and to
retain all mail relating to the Collateral of such Borrower and forward all
other mail to such Borrower, (f) at any time that an Event of Default has
occurred and is continuing, make, settle, and adjust all claims under such
Borrower's policies of insurance and make all determinations and decisions with
respect to such policies of insurance, and (g) at any time that an Event of
Default has occurred and is continuing, settle and adjust disputes and claims
respecting the Accounts of such Borrower directly with Account Debtors, for
amounts and upon terms that Foothill determines to be reasonable, and Foothill
may cause to be executed and delivered any documents and releases that Foothill
determines to be necessary.  The appointment of Foothill as such Borrower's
attorney, and each and every one of Foothill's rights and powers, being coupled
with an interest, is irrevocable until all of the Obligations have been fully
and finally repaid and performed and Foothill's obligation to extend credit
hereunder is terminated.

                 4.6      RIGHT TO INSPECT.  Foothill (through any of its
officers, employees, or agents) shall have the right, from time to time during
normal business hours hereafter to inspect Borrowers' Books and to check, test,
and appraise the Collateral in order to verify Borrowers' financial condition
or the amount, quality, value, condition of, or any other matter relating to,
the Collateral.

         5.      REPRESENTATIONS AND WARRANTIES.

                 In order to induce Foothill to enter into this Agreement, each
Borrower makes the following representations and warranties which shall be
true, correct, and complete in all respects as of the date hereof, and shall be
true, correct, and complete in all respects as of the Closing Date, and at and
as of the date of the making of each Advance made thereafter, as though made on
and as of the date of such Advance or Term Loan (except to the extent that such
representations and warranties relate solely to an earlier date) and such
representations and warranties shall survive the execution and delivery of this
Agreement:

                 5.1      NO ENCUMBRANCES.  Each Borrower has good and
indefeasible title to its Collateral, free and clear of Liens except for
Permitted Liens.

Borrower are bona fide existing obligations created by the sale and delivery of
Inventory or the rendition of services to Account Debtors in the ordinary
course of such Borrower's business, unconditionally owed to such Borrower
without defenses, disputes, offsets, counterclaims, or rights of return or
cancellation.  The property giving rise to such Eligible Accounts has been
delivered to the Account Debtor, or to the Account Debtor's agent for immediate
shipment to and unconditional acceptance by the Account Debtor.  Borrowers have
not received notice of actual or imminent bankruptcy, insolvency, or material
impairment of the financial condition of any Account Debtor regarding any
Eligible Account.

6.12.

                          (b)     Set forth on Schedule 5.7, is a complete and

and non-assessable.

                          (c)     Except as set forth on Schedule 5.7, no
capital stock (or any securities, instruments, warrants, options, purchase
rights, conversion or exchange rights, calls, commitments or claims of any
character convertible into or exercisable for capital stock) of any direct or
indirect Subsidiary of any Borrower is subject to the issuance of any security,
instrument, warrant, option, purchase right, conversion or exchange right,
call, commitment or claim of any right, title, or interest therein or thereto.

                 5.8      DUE AUTHORIZATION; NO CONFLICT.

                          (a)     The execution, delivery, and performance by
each Borrower of this Agreement and the Loan Documents to which it is a party
have been duly authorized by all necessary corporate action.

                          (b)     The execution, delivery, and performance by
each Borrower of this Agreement and the Loan Documents to which it is a party
do not and will not (i) violate any provision of federal, state, or local law
or regulation (including Regulations G, T, U, and X of the Federal Reserve
Board) applicable to such Borrower, the Governing Documents of such Borrower,
or any order, judgment, or decree of any court or other Governmental Authority
binding on such Borrower, (ii) conflict with, result in a breach of, or
constitute (with due notice or lapse of time or both) a default under any

financing statements, fixture filings, and mortgages, the execution, delivery,

                          (d)     This Agreement and the Loan Documents to
which any Borrower is a party, and all other documents contemplated hereby and
thereby, when executed and delivered by such Borrower will be the legally valid
and binding obligations of such Borrower, enforceable against such Borrower in
accordance with their respective terms,





                                       27
<PAGE>   33
except as enforcement may be limited by equitable principles or by bankruptcy,
insolvency, reorganization, moratorium, or similar laws relating to or limiting
creditors' rights generally.

                          (e)     The Liens granted by each Borrower to
Foothill in and to its properties and assets pursuant to this Agreement and the
other Loan Documents are validly created, perfected, and first priority Liens,
subject only to Permitted Liens.

                 5.9      LITIGATION.  There are no actions or proceedings
pending by or against any Borrower before any court or administrative agency
and no Borrower has any knowledge or belief of any pending, threatened, or
imminent litigation, governmental investigations, or claims, complaints,
actions, or prosecutions involving any Borrower or any guarantor of the
Obligations, except for:  (a) ongoing collection matters in which a Borrower is
the plaintiff; (b) matters disclosed on Schedule 5.9; and (c) matters arising
after the date hereof that, if decided adversely to a Borrower, would not have
a Material Adverse Change.

                 5.10     NO MATERIAL ADVERSE CHANGE.  All financial statements
relating to any Borrower or any guarantor of the Obligations that have been
delivered by any Borrower to Foothill have been prepared in accordance with
GAAP (except, in the case of unaudited financial statements, for the lack of
footnotes and being subject to year-end audit adjustments) and fairly present
such Borrower's (or such guarantor's, as applicable) financial condition as of
the date thereof and such Borrower's results of operations for the period then
ended.  There has not been a Material Adverse Change with respect to any
Borrower (or such guarantor, as applicable) since December 31, 1997, the date
of the latest financial statements submitted to Foothill on or before the
Closing Date.

                 5.11     SOLVENCY.  Upon consummation of the financing that is
the subject of this Agreement, each Borrower shall be Solvent.  No transfer of
property is being made by any Borrower and no obligation is being incurred by
any Borrower in connection with the transactions contemplated by this Agreement
or the other Loan Documents with the intent to hinder, delay, or defraud either
present or future creditors of any Borrower.

                 5.12     EMPLOYEE BENEFITS.  None of Borrowers, any of their
Subsidiaries, or any of their ERISA Affiliates maintains or contributes to any
Benefit Plan, other than those listed on Schedule 5.12.  Each Borrower, each of
its Subsidiaries and each ERISA Affiliate have satisfied the minimum funding
standards of ERISA and the IRC with respect to each Benefit Plan to which it is
obligated to contribute.  No ERISA Event has occurred nor has any other event
occurred that may result in an ERISA Event that reasonably could be expected to
result in a Material Adverse Change.  None of Borrowers or their Subsidiaries,
any ERISA Affiliate, or any fiduciary of any Plan is subject to any direct or
indirect liability with respect to any Plan under any applicable law, treaty,
rule, regulation, or agreement.  None of Borrowers or their Subsidiaries or any
ERISA Affiliate is required to provide security to any Plan under Section
401(a)(29) of the IRC.

<PAGE>   34
                 5.13     ENVIRONMENTAL CONDITION.  None of Borrowers'
properties or assets has ever been used by any Borrower or, to the best of each
Borrower's knowledge, by previous owners or operators in the disposal of, or to
produce, store, handle, treat, release, or transport, any Hazardous Materials.
None of Borrowers' properties or assets has ever been designated or identified
in any manner pursuant to any environmental protection statute as a Hazardous
Materials disposal site, or a candidate for closure pursuant to any
environmental protection statute.  No Lien arising under any environmental
protection statute has attached to any revenues or to any real or personal
property owned or operated by any Borrower.  No Borrower has received a
summons, citation, notice, or directive from the Environmental Protection
Agency or any other federal or state governmental agency concerning any action
or omission by any Borrower resulting in the releasing or disposing of
Hazardous Materials into the environment.

                 5.14     YEAR 2000 COMPLIANCE.

                          (a)     On the basis of a comprehensive inventory,
review and assessment currently being undertaken by each Borrower of such
Borrower's computer applications utilized by such Borrower or contained in
products produced or sold by such Borrower, and upon inquiry made of each
Borrower's material suppliers and vendors, each Borrower's management is of the
considered view that such Borrower, its products, and all such suppliers and
vendors will be Year 2000 Compliant before October 1, 1999.

                          (b)     Each Borrower (i) has undertaken a detailed
inventory, review and assessment of all areas within its business and
operations that could be adversely affected by the failure of such Borrower or
its products to be Year 2000 Compliant on a timely basis, (ii) is developing a
detail plan and timeline for becoming Year 2000 Compliant on a timely basis,
and (iii) to date, is implementing that plan in accordance with that timetable
in all material respects.  Each Borrower reasonably anticipates that it will be
Year 2000 Compliant on a timely basis.

         6.      AFFIRMATIVE COVENANTS.

                 Each Borrower covenants and agrees that, so long as any credit
hereunder shall be available and until full and final payment of the
Obligations, such Borrower shall do all of the following:

                 6.1      ACCOUNTING SYSTEM.  Maintain a standard and modern
system of accounting that enables such Borrower to produce financial statements
in accordance with GAAP, and maintain records pertaining to its Collateral that
contain information as from time to time may be requested by Foothill.  Such
Borrower also shall keep a modern inventory reporting system that shows all
additions, sales, claims, returns, and allowances with respect to its
Inventory; provided, however, that this does not require Borrower to maintain a
perpetual Inventory system.





                                       29
<PAGE>   35

Foothill shall request; (i) upon Foothill's request, Borrowers' electronic

condition of such Borrower as Foothill may request from time to time.  Original
sales invoices evidencing daily sales shall be mailed by such Borrower to each
Account Debtor and, at Foothill's direction after the occurrence of an Event of
Default, the invoices shall indicate on their face that such Borrower's Account
has been assigned to Foothill and that all payments are to be made directly to
Foothill.

                 6.3      FINANCIAL STATEMENTS, REPORTS, CERTIFICATES.  Deliver
to Foothill:  (a) as soon as available, but in any event within 45 days after
the end of each month during each of such Borrower's fiscal years, a company
prepared balance sheet, income statement, and, commencing with the month of
August 1998, statement of cash flow covering such Borrower's operations during
such period; and (b) as soon as available, but in any event within 90 days
after the end of each of such IRIS's fiscal years, financial statements of IRIS

reasonably acceptable to Foothill and certified, without any qualifications, by
such accountants to have been prepared in accordance with GAAP, together with a
certificate of such accountants addressed to Foothill stating that such
accountants do not have knowledge of the existence of any Default or Event of
Default.  Such audited financial statements shall include a balance sheet,
profit and loss statement, and statement of cash flow and, if prepared, such
accountants' letter to management.

                          Together with the above, IRIS also shall deliver to
Foothill IRIS' Form 10-Q Quarterly Reports, Form 10-K Annual Reports, and Form
8-K Current Reports, and any other filings made by IRIS with the Securities and

reasonably requested by Foothill relating to the financial condition of IRIS.





                                       30
<PAGE>   36
                          Each month, together with the financial statements
provided pursuant to Section 6.3(a), IRIS shall deliver to Foothill a
certificate signed by its chief financial officer to the effect that, to the
best of his knowledge:  (i) all financial statements delivered or caused to be
delivered to Foothill hereunder have been prepared in accordance with GAAP
(except, in the case of unaudited financial statements, for the lack of
footnotes and being subject to year-end audit adjustments) and fairly present
the financial condition of Borrowers, (ii) the representations and warranties
of Borrowers contained in this Agreement and the other Loan Documents are true
and correct in all material respects on and as of the date of such certificate,
as though made on and as of such date (except to the extent that such
representations and warranties relate solely to an earlier date), (iii) for
each month that also is the date on which a financial covenant in Section 7.20
is to be tested, a Compliance Certificate demonstrating in reasonable detail
compliance at the end of such period with the applicable financial covenants
contained in Section 7.20, and (iv) on the date of delivery of such certificate
to Foothill there does not exist any condition or event that constitutes a
Default or Event of Default (or, in the case of clauses (i), (ii), or (iii), to
the extent of any non-compliance, describing such non-compliance as to which he
or she may have knowledge and what action Borrowers have taken, is taking, or
propose to take with respect thereto).

                          Each Borrower shall have issued written instructions
to its independent certified public accountants authorizing them to communicate
with Foothill and to release to Foothill whatever financial information
concerning such Borrower that Foothill may request.  Each Borrower hereby
irrevocably authorizes and directs all auditors, accountants, or other third
parties to deliver to Foothill, at such Borrower's expense, copies of such
Borrower's financial statements, papers related thereto, and other accounting
records of any nature in their possession, and to disclose to Foothill any
information they may have regarding such Borrower's business affairs and
financial conditions.  Prior to the occurrence of an Event of Default, Foothill
shall notify IRIS telephonically if it intends to contact Borrower's auditors
or accountants.

                 6.4      TAX RETURNS.  Deliver to Foothill copies of each of
such Borrower's future federal income tax returns, and any amendments thereto,
within 30 days of the filing thereof with the Internal Revenue Service.

                 6.5      INTENTIONALLY OMITTED.

                 6.6      RETURNS.  Cause returns and allowances, if any, as
between such Borrower and its Account Debtors to be on the same basis and in
accordance with the usual customary practices of such Borrower, as they exist
at the time of the execution and delivery of this Agreement.  If, at a time
when no Event of Default has occurred and is continuing, any Account Debtor
returns any Inventory to such Borrower, such Borrower promptly shall determine
the





                                       31
<PAGE>   37
reason for such return and, if such Borrower accepts such return, issue a
credit memorandum (with a copy to be sent to Foothill) in the appropriate
amount to such Account Debtor.  If, at a time when an Event of Default has
occurred and is continuing, any Account Debtor returns any Inventory to such
Borrower, such Borrower promptly shall determine the reason for such return
and, if Foothill consents (which consent shall not be unreasonably withheld),
issue a credit memorandum (with a copy to be sent to Foothill) in the
appropriate amount to such Account Debtor.

                 6.7      TITLE TO EQUIPMENT.  Upon Foothill's request, such
Borrower immediately shall deliver to Foothill, properly endorsed, any and all
evidences of ownership of, certificates of title, or applications for title to
any items of its Equipment.

                 6.8      MAINTENANCE OF EQUIPMENT.  Maintain its Equipment in
good operating condition and repair (ordinary wear and tear excepted), and make
all necessary replacements thereto so that the value and operating efficiency
thereof shall at all times be maintained and preserved.  Other than those items
of Equipment that constitute fixtures on the Closing Date, such Borrower shall
not permit any item of its Equipment to become a fixture to real estate or an
accession to other property, and such Equipment shall at all times remain
personal property.

                 6.9      TAXES.  Cause all assessments and taxes, whether
real, personal, or otherwise, due or payable by, or imposed, levied, or
assessed against such Borrower or any of its property to be paid in full,
before delinquency or before the expiration of any extension period, except to
the extent that the validity of such assessment or tax  shall be the subject of
a Permitted Protest.  Such Borrower shall make due and timely payment or
deposit of all such federal, state, and local taxes, assessments, or
contributions required of it by law, and will execute and deliver to Foothill,
on demand, appropriate certificates attesting to the payment thereof or deposit
with respect thereto.  Such Borrower will make timely payment or deposit of all
tax payments and withholding taxes required of it by applicable laws, including
those laws concerning F.I.C.A., F.U.T.A., state disability, and local, state,
and federal income taxes, and will, upon request, furnish Foothill with proof
satisfactory to Foothill indicating that such Borrower has made such payments
or deposits.

                 6.10     INSURANCE.

                          (a)     At its expense, keep the Collateral insured
against loss or damage by fire, theft, explosion, sprinklers, and all other
hazards and risks, and in such amounts, as are ordinarily insured against by
other owners in similar businesses.  Such Borrower also shall maintain business
interruption, public liability, product liability, and property damage
insurance relating to such Borrower's ownership and use of the Collateral, as
well as insurance against larceny, embezzlement, and criminal misappropriation.

                          (b)     All such policies of insurance shall be in
such form, with such companies, and in such amounts as may be reasonably
satisfactory to Foothill.  All insurance required herein shall be written by
companies which are authorized to do insurance business in the State of
California.  All hazard insurance and such other insurance as Foothill shall
specify, shall contain a California Form 438BFU (NS) mortgagee endorsement, or
an equivalent endorsement satisfactory to Foothill, showing Foothill as sole
loss payee thereof,





                                       32
<PAGE>   38
and shall contain a waiver of warranties.  Every policy of insurance referred
to in this Section 6.10 shall contain an agreement by the insurer that it will
not cancel such policy except after 30 days prior written notice to Foothill
and that any loss payable thereunder shall be payable notwithstanding any act
or negligence of such Borrower or Foothill which might, absent such agreement,
result in a forfeiture of all or a part of such insurance payment.  Such
Borrower shall deliver to Foothill certified copies of such policies of
insurance and evidence of the payment of all premiums therefor.

                          (c)     Original policies or certificates thereof
satisfactory to Foothill evidencing such insurance shall be delivered to
Foothill at least 30 days prior to the expiration of the existing or preceding
policies.  Borrowers shall give Foothill prompt notice of any loss covered by
such insurance, and Foothill shall have the right to adjust any loss.  Foothill
shall have the exclusive right to adjust all losses payable under any such
insurance policies without any liability to Borrowers whatsoever in respect of
such adjustments.  Any monies received as payment for any loss under any
insurance policy including the insurance policies mentioned above, shall be
paid over to Foothill to be applied at the option of Foothill either to the
prepayment of the Obligations without premium, in such order or manner as
Foothill may elect, or shall be disbursed to Borrowers.  Upon the occurrence of
an Event of Default, Foothill shall have the right to apply all prepaid
premiums to the payment of the Obligations in such order or form as Foothill
shall determine.

                          (d)     Borrowers shall not take out separate
insurance concurrent in form or contributing in the event of loss with that
required to be maintained under this Section 6.10, unless Foothill is included
thereon as named insured with the loss payable to Foothill under a standard
California 438BFU (NS) Mortgagee endorsement, or its local equivalent.  Such
Borrower immediately shall notify Foothill whenever such separate insurance is
taken out, specifying the insurer thereunder and full particulars as to the
policies evidencing the same, and originals of such policies immediately shall
be provided to Foothill.

                 6.11     NO SETOFFS OR COUNTERCLAIMS.  Make payments hereunder
and under the other Loan Documents by or on behalf of such Borrower without
setoff or counterclaim and free and clear of, and without deduction or
withholding for or on account of, any federal, state, or local taxes.

                 6.12     LOCATION OF INVENTORY AND EQUIPMENT.  Keep its
Inventory and Equipment only at the locations identified on Schedule 6.12;
provided, however, that Borrowers may amend Schedule 6.12 so long as such
amendment occurs by written notice to Foothill not less than 30 days prior to
the date on which the Inventory or Equipment of Borrowers is moved to such new
location, so long as such new location is within the continental United States,
and so long as, at the time of such written notification, Borrowers provide any
financing statements or fixture filings necessary to perfect and continue
perfected Foothill's security interests in such assets and also provides to
Foothill a Collateral Access Agreement.

of all applicable laws, rules, regulations, and orders of all federal, state or
local governmental authorities, including the Food, Drug, and Cosmetic Act, the

individually or in the aggregate, could not reasonably be expected to have a
Material Adverse Change.

Event and any action that is being taking with respect thereto by such
Borrower, any such Subsidiary or ERISA Affiliate, and any action taken or

Subsidiary, as applicable, shall be deemed to know all facts known by the

respect to such request, and (iii) promptly, and in any event within three
Business Days after receipt by such Borrower, any of its Subsidiaries or, to
the knowledge of such Borrower, any ERISA Affiliate, of the PBGC's intention to
terminate a Benefit Plan or to have a trustee appointed to administer a Benefit
Plan, copies of each such notice.

                          (b)     Cause to be delivered to Foothill, upon
Foothill's request, each of the following:  (i) a copy of each Plan (or, where
any such plan is not in writing, complete description thereof) (and if
applicable, related trust agreements or other funding instruments) and all
amendments thereto, all written interpretations thereof and written
descriptions thereof that have been distributed to employees or former
employees of such Borrower or its Subsidiaries; (ii) the most recent

provided to such Borrower or any ERISA Affiliate regarding withdrawal liability
under any Multiemployer Plan; and (vii) the aggregate amount of the most recent
annual payments made to former employees of such Borrower or its Subsidiaries

payable under any leases to which such Borrower is a party or by which such
Borrower's properties and assets are bound, unless such payments are the
subject of a Permitted Protest.  To the extent that such Borrower fails timely
to make payment of such rents and other amounts payable when due under its
leases, Foothill shall be entitled, in its discretion, to reserve an amount
equal to such unpaid amounts against the Borrowing Base.

                 6.16     YEAR 2000 COMPLIANCE.  Each Borrower will be Year

continuance or renewal of any Permitted Liens associated therewith) so long as:
(i) the terms and conditions of such refinancings, renewals, or extensions do
not materially impair the prospects of repayment of the Obligations by
Borrowers, (ii) the net cash proceeds of such refinancings, renewals, or
extensions do not result in an increase in the aggregate principal amount of
the Indebtedness so refinanced, renewed, or extended, (iii) such refinancings,
renewals, refundings, or extensions do not result in a shortening of the
average weighted maturity of the Indebtedness so refinanced, renewed, or
extended, and (iv) to the extent that Indebtedness that is refinanced was
subordinated in right of payment to the Obligations, then the subordination

<PAGE>   41
Indebtedness is refinanced under Section 7.1(d) and so long as the replacement
Liens only encumber those assets or property that secured the original
Indebtedness).

hereafter be stored with a bailee, warehouseman, or similar party without
Foothill's prior written consent.

         8.      EVENTS OF DEFAULT.

                 Any one or more of the following events shall constitute an
event of default (each, an "Event of Default") under this Agreement:

                 8.1      If Borrowers fail to pay when due and payable or when
declared due and payable, any portion of the Obligations (whether of principal,
interest (including any interest which, but for the provisions of the
Bankruptcy Code, would have accrued on such amounts), fees and charges due
Foothill, reimbursement of Foothill Expenses, or other amounts constituting
Obligations);

                 8.2      If any Borrower fails to perform, keep, or observe
any term, provision, condition, covenant, or agreement contained in this
Agreement, in any of the Loan Documents, or in any other present or future
agreement between such Borrower and Foothill; provided, however, that
Borrowers' failure to perform, keep, or observe the terms of Sections 6.2, 6.3,
6.4, 6.7, 6.8, 6.13 or 6.15 shall not constitute an Event of Default unless
such failure continues for five days or more;

                 8.3      If there is a Material Adverse Change;

                 8.4      If any material portion of any Borrower's properties
or assets is attached, seized, subjected to a writ or distress warrant, or is
levied upon, or comes into the possession of any third Person and such
attachment, seizure or levy is not released within 15 days of the date thereof;

                 8.5      If an Insolvency Proceeding is commenced by any
Borrower;

                 8.6      If an Insolvency Proceeding is commenced against any
Borrower and any of the following events occur:  (a) such Borrower consents to
the institution of the Insolvency Proceeding against it; (b) the petition
commencing the Insolvency Proceeding is not timely controverted; (c) the
petition commencing the Insolvency Proceeding is not dismissed within 60
calendar days of the date of the filing thereof; provided, however, that,
during the pendency of such period, Foothill shall be relieved of its
obligation to extend credit hereunder; (d) an interim trustee is appointed to
take possession of all or a substantial portion of the properties or assets of,
or to operate all or any substantial portion of the business of, such Borrower;
or (e) an order for relief shall have been issued or entered therein;

                 8.7      If any Borrower is enjoined, restrained, or in any
way prevented by court order from continuing to conduct all or any material
part of its business affairs and such injunction or restraint continues for
more than five days;

                 8.8      If a notice of Lien, levy, or assessment is filed of
record with respect to any of any Borrower's properties or assets by the United
States Government, or any department, agency, or instrumentality thereof, or by
any state, county, municipal, or





                                       40
<PAGE>   46
governmental agency, or if any taxes or debts owing at any time hereafter to
any one or more of such entities becomes a Lien, whether choate or otherwise,
upon any of such Borrower's properties or assets and the same is not paid on
the payment date thereof;

                 8.9      If a judgment or other claim becomes a Lien or
encumbrance upon any material portion of any Borrower's properties or assets
and such Lien or encumbrance is not discharged or released within 30 days of
the date thereof;

                 8.10     If there is a default in any agreement relating to
Indebtedness to which any Borrower is a party with one or more third Persons
and such default (a) occurs at the final maturity of the obligations
thereunder, or (b) results in a right by such third Person(s), irrespective of
whether exercised, to accelerate the maturity of such Borrower's obligations
thereunder;

                 8.11     If any Borrower makes any payment on account of
Indebtedness that has been contractually subordinated in right of payment to
the payment of the Obligations (including the Subordinate Indebtedness), except
to the extent such payment is permitted by the terms of the subordination
provisions applicable to such Indebtedness or the Subordination Agreement;

                 8.12     If any material misstatement or misrepresentation
exists now or hereafter in any warranty, representation, statement, or report
made to Foothill by any Borrower or any officer, employee, agent, or director
of any Borrower, or if any such material warranty or representation is
withdrawn; or

                 8.13     If the obligation of a guarantor, if any, under its
guaranty or other third Person under any Loan Document is limited or terminated
by operation of law or by the guarantor or other third Person thereunder, or
any such guarantor or other third Person becomes the subject of an Insolvency
Proceeding.

         9.      FOOTHILL'S RIGHTS AND REMEDIES.

                 9.1      RIGHTS AND REMEDIES.  Upon the occurrence, and during
the continuation, of an Event of Default Foothill may, at its election, without
notice of its election and without demand, do any one or more of the following,
all of which are authorized by Borrowers:

                          (a)     Declare all Obligations, whether evidenced by
this Agreement, by any of the other Loan Documents, or otherwise, immediately
due and payable;

                          (b)     Cease advancing money or extending credit to
or for the benefit of Borrowers under this Agreement, under any of the Loan
Documents, or under any other agreement between Borrowers and Foothill;





                                       41
<PAGE>   47
                          (c)     Terminate this Agreement and any of the other
Loan Documents as to any future liability or obligation of Foothill, but
without affecting Foothill's rights and security interests in the Collateral
and without affecting the Obligations;

                          (d)     Settle or adjust disputes and claims directly
with Account Debtors for amounts and upon terms which Foothill considers
advisable, and in such cases, Foothill will credit Borrowers' Loan Account with
only the net amounts received by Foothill in payment of such disputed Accounts
after deducting all Foothill Expenses incurred or expended in connection
therewith;

                          (e)     Cause Borrowers to hold all of their returned
Inventory in trust for Foothill, segregate all such returned Inventory from all
other property of any Borrower or in any Borrower's possession and
conspicuously label said returned Inventory as the property of Foothill;

                          (f)     Without notice to or demand upon any Borrower
or any guarantor, make such payments and do such acts as Foothill considers
necessary or reasonable to protect its security interests in the Collateral.
Borrowers agree to assemble the Collateral if Foothill so requires, and to make
the Collateral available to Foothill as Foothill may designate.  Each Borrower
authorizes Foothill to enter the premises where the Collateral is located, to
take and maintain possession of the Collateral, or any part of it, and to pay,
purchase, contest, or compromise any encumbrance, charge, or Lien that in
Foothill's determination appears to conflict with its security interests and to
pay all expenses incurred in connection therewith.  With respect to any of
Borrowers' owned or leased premises, each Borrower hereby grants Foothill a
license to enter into possession of such premises and to occupy the same,
without charge, for up to 120 days in order to exercise any of Foothill's
rights or remedies provided herein, at law, in equity, or otherwise;

                          (g)     Without notice to any Borrower (such notice
being expressly waived), and without constituting a retention of any collateral
in satisfaction of an obligation (within the meaning of Section 9505 of the
Code), set off and apply to the Obligations any and all (i) balances and
deposits of any Borrower held by Foothill (including any amounts received in
the Lockbox Accounts), or (ii) indebtedness at any time owing to or for the
credit or the account of any Borrower held by Foothill;

                          (h)     Hold, as cash collateral, any and all
balances and deposits of any Borrower held by Foothill, and any amounts
received in the Lockbox Accounts, to secure the full and final repayment of all
of the Obligations;

                          (i)     Ship, reclaim, recover, store, finish,
maintain, repair, prepare for sale, advertise for sale, and sell (in the manner
provided for herein) the Collateral.  Foothill is hereby granted a license or
other right to use, without charge, any 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





                                       42
<PAGE>   48
the Collateral, in completing production of, advertising for sale, and selling
any Collateral and each Borrower's rights under all licenses and all franchise
agreements shall inure to Foothill's benefit;

                          (j)     Sell the Collateral at either a public or
private sale, or both, by way of one or more contracts or transactions, for
cash or on terms, in such manner and at such places (including any Borrower's
premises) as Foothill determines is commercially reasonable.  It is not
necessary that the Collateral be present at any such sale;

                          (k)     Foothill shall give notice of the disposition
of the Collateral as follows:

                                  (1)      Foothill shall give Borrowers and
each holder of a security interest in the Collateral who has filed with
Foothill a written request for notice, a notice in writing of the time and
place of public sale, or, if the sale is a private sale or some other
disposition other than a public sale is to be made of the Collateral, then the
time on or after which the private sale or other disposition is to be made;

                                  (2)      The notice shall be personally
delivered or mailed, postage prepaid, to Borrowers as provided in Section 12,
at least five days before the date fixed for the sale, or at least five days
before the date on or after which the private sale or other disposition is to
be made; no notice needs to be given prior to the disposition of any portion of
the Collateral that is perishable or threatens to decline speedily in value or
that is of a type customarily sold on a recognized market.  Notice to Persons
other than Borrowers claiming an interest in the Collateral shall be sent to
such addresses as they have furnished to Foothill;

                                  (3)      If the sale is to be a public sale,
Foothill also shall give notice of the time and place by publishing a notice
one time at least 5 days before the date of the sale in a newspaper of general
circulation in the county in which the sale is to be held;

                          (l)     Foothill may credit bid and purchase at any
public sale; and

                          (m)     Any deficiency that exists after disposition
of the Collateral as provided above will be paid immediately by Borrowers.  Any
excess will be returned, without interest and subject to the rights of third
Persons, by Foothill to Borrowers.

                 9.2      REMEDIES CUMULATIVE.  Foothill's rights and remedies
under this Agreement, the Loan Documents, and all other agreements shall be
cumulative.  Foothill shall have all other rights and remedies not inconsistent
herewith as provided under the Code, by law, or in equity.  No exercise by
Foothill of one right or remedy shall be deemed an election, and no waiver by
Foothill of any Event of Default shall be deemed a continuing waiver.  No delay
by Foothill shall constitute a waiver, election, or acquiescence by it.





                                       43
<PAGE>   49
         10.     TAXES AND EXPENSES.

                 If any Borrower fails to pay any monies (whether taxes,
assessments, insurance premiums, or, in the case of leased properties or
assets, rents or other amounts payable under such leases) due to third Persons,
or fails to make any deposits or furnish any required proof of payment or
deposit, all as required under the terms of this Agreement, then, to the extent
that Foothill determines that such failure by such Borrower could result in a
Material Adverse Change, in its discretion and without prior notice to
Borrowers, Foothill may do any or all of the following:  (a) make payment of
the same or any part thereof; (b) set up such reserves in Borrowers' Loan
Account as Foothill deems necessary to protect Foothill from the exposure
created by such failure; or (c) obtain and maintain insurance policies of the
type described in Section 6.10, and take any action with respect to such
policies as Foothill deems prudent.  Any such amounts paid by Foothill shall
constitute Foothill Expenses.  Any such payments made by Foothill shall not
constitute an agreement by Foothill to make similar payments in the future or a
waiver by Foothill of any Event of Default under this Agreement.  Foothill need
not inquire as to, or contest the validity of, any such expense, tax, or Lien
and the receipt of the usual official notice for the payment thereof shall be
conclusive evidence that the same was validly due and owing.

         11.     WAIVERS; INDEMNIFICATION.

                 11.1     DEMAND; PROTEST; ETC.  Each Borrower waives demand,
protest, notice of protest, notice of default or dishonor, notice of payment
and nonpayment, nonpayment at maturity, release, compromise, settlement,
extension, or renewal of accounts, documents, instruments, chattel paper, and
guarantees at any time held by Foothill on which such Borrower may in any way
be liable.

                 11.2     FOOTHILL'S LIABILITY FOR COLLATERAL.  So long as
Foothill complies with its obligations, if any, under Section 9207 of the Code,
Foothill shall not in any way or manner be liable or responsible for:  (a) the
safekeeping of the Collateral; (b) any loss or damage thereto occurring or
arising in any manner or fashion from any cause; (c) any diminution in the
value thereof; or (d) any act or default of any carrier, warehouseman, bailee,
forwarding agency, or other Person.  All risk of loss, damage, or destruction
of the Collateral shall be borne by Borrowers.

                 11.3     INDEMNIFICATION.  Borrowers shall pay, indemnify,
defend, and hold Foothill, each Participant, and each of their respective
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 reasonable 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 (including any of the foregoing





                                       44
<PAGE>   50
arising out of the administration of the credit facilities hereunder on a joint
borrowing basis) 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").  Borrowers shall have no obligation to any
Indemnified Person under this Section 11.3 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.

                 11.4     JOINT BORROWERS.

                          (a)     Each Borrower agrees that it is jointly and
severally, directly and primarily liable to Foothill for payment in full of all
Obligations, whether for principal, interest or otherwise and that such
liability is independent of the duties, obligations, and liabilities of the
other Borrowers.  Foothill may bring a separate action or actions on each, any,
or all of the Obligations against any Borrower, whether action is brought
against the other Borrowers or whether the other Borrowers are joined in such
action.  In the event that any Borrower fails to make any payment of any
Obligations on or before the due date thereof, the other Borrowers immediately
shall cause such payment to be made or each of such Obligations to be
performed, kept, observed, or fulfilled.

                          (b)     The Loan Documents are a primary and original
obligation of each Borrower, are not the creation of a surety relationship, and
are an absolute, unconditional, and continuing promise of payment and
performance which shall remain in full force and effect without respect to
future changes in conditions, including any change of law or any invalidity or
irregularity with respect to the Loan Documents.  Each Borrower agrees that its
liability under the Loan Documents shall be immediate and shall not be
contingent upon the exercise or enforcement by Foothill of whatever remedies it
may have against the other Borrowers, or the enforcement of any lien or
realization upon any security Foothill may at any time possess.  Each Borrower
consents and agrees that Foothill shall be under no obligation (under Section
2899 or 3433 of the California Civil Code or otherwise) to marshal any assets
of any Borrower against or in payment of any or all of the Obligations.

                          (c)     Each Borrower acknowledges that it is
presently informed as to the financial condition of the other Borrowers and of
all other circumstances which a diligent inquiry would reveal and which bear
upon the risk of nonpayment of the Obligations.  Each Borrower hereby covenants
that it will continue to keep informed as to the financial condition of the
other Borrowers, the status of the other Borrowers and of all circumstances
which bear upon the risk of nonpayment of the Obligations.  Absent a written
request from any Borrower to Foothill for information, such Borrower hereby
waives any and all rights it may have to





                                       45
<PAGE>   51
require Foothill to disclose to such Borrower any information which Foothill
may now or hereafter acquire concerning the condition or circumstances of the
other Borrowers.

                          (d)     The liability of each Borrower under the Loan
Documents includes Obligations arising under successive transactions
continuing, compromising, extending, increasing, modifying, releasing, or
renewing the Obligations, changing the interest rate, payment terms, or other
terms and conditions thereof, or creating new or additional Obligations after
prior Obligations have been satisfied in whole or in part.  To the maximum
extent permitted by law, each Borrower hereby waives any right to revoke its
liability under the Loan Documents as to future indebtedness, and in connection
therewith, each Borrower hereby waives any rights it may have under Section
2815 of the California Civil Code.  If such a revocation is effective
notwithstanding the foregoing waiver, each Borrower acknowledges and agrees
that (a) no such revocation shall be effective until written notice thereof has
been received by Foothill, (b) no such revocation shall apply to any
Obligations in existence on such date (including, any subsequent continuation,
extension, or renewal thereof, or change in the interest rate, payment terms,
or other terms and conditions thereof), (c) no such revocation shall apply to
any Obligations made or created after such date to the extent made or created
pursuant to a legally binding commitment of Foothill in existence on the date
of such revocation, (d) no payment by such Borrower or from any other source
prior to the date of such revocation shall reduce the maximum obligation of the
other Borrowers hereunder, and (e) any payment by such Borrower or from any
source other than Borrowers, subsequent to the date of such revocation, shall
first be applied to that portion of the Obligations as to which the revocation
is effective and which are not, therefore, guaranteed hereunder, and to the
extent so applied shall not reduce the maximum obligation of each Borrower
hereunder.

                          (e)     (i)      Each Borrower absolutely,
unconditionally, knowingly, and expressly waives:

                                  (1)      (A) notice of acceptance hereof; (B)
         notice of any loans or other financial accommodations made or extended
         under the Loan Documents or the creation or existence of any
         Obligations; (C) notice of the amount of the Obligations, subject,
         however, to each Borrower's right to make inquiry of Foothill to
         ascertain the amount of the Obligations at any reasonable time; (D)
         notice of any adverse change in the financial condition of the other
         Borrowers or of any other fact that might increase such Borrower's
         risk hereunder; (E) notice of presentment for payment, demand,
         protest, and notice thereof as to any instruments among the Loan
         Documents; and (F) all notices (except if such notice is specifically
         required to be given to Borrowers hereunder or under the Loan
         Documents) and demands to which such Borrower might otherwise be
         entitled.

                                  (2)      its right, under Sections 2845 or
         2850 of the California Civil Code, or otherwise, to require Foothill
         to institute suit against, or to exhaust any rights and remedies which
         Foothill has or may have against, the other Borrowers or





                                       46
<PAGE>   52
         any third party, or against any Collateral provided by the other
         Borrowers, or any third party.   In this regard, each Borrower agrees
         that it is bound to the payment of all Obligations, whether now
         existing or hereafter accruing, as fully as if such Obligations were
         directly owing to Foothill by such Borrower.  Each Borrower further
         waives any defense arising by reason of any disability or other
         defense (other than the defense that the Obligations shall have been
         fully and finally performed and indefeasibly paid) of the other
         Borrowers or by reason of the cessation from any cause whatsoever of
         the liability of the other Borrowers in respect thereof.

                                  (3)      (A) any rights to assert against
         Foothill any defense (legal or equitable), set-off, counterclaim, or
         claim which such Borrower may now or at any time hereafter have
         against the other Borrowers or any other party liable to Foothill; (B)
         any defense, set-off, counterclaim, or claim, of any kind or nature,
         arising directly or indirectly from the present or future lack of
         perfection, sufficiency, validity, or enforceability of the
         Obligations or any security therefor; (C) any defense such Borrower
         has to performance hereunder, and any right such Borrower has to be
         exonerated, provided by Sections 2819, 2822, or 2825 of the California
         Civil Code, or otherwise, arising by reason of:  the impairment or
         suspension of Foothill's rights or remedies against the other
         Borrowers; the alteration by Foothill of the Obligations; any
         discharge of the other Borrowers' obligations to Foothill by operation
         of law as a result of Foothill's intervention or omission; or the
         acceptance by Foothill of anything in partial satisfaction of the
         Obligations; (D) the benefit of any statute of limitations affecting
         such Borrower's liability hereunder or the enforcement thereof, and
         any act which shall defer or delay the operation of any statute of
         limitations applicable to the Obligations shall similarly operate to
         defer or delay the operation of such statute of limitations applicable
         to such Borrower's liability hereunder.

                          (ii)    Until such time as all Obligations have been
fully, finally, and indefeasibly paid in full, in cash, each Borrower hereby
absolutely, unconditionally, knowingly, and expressly postpones:  (1) any right
of subrogation such Borrower has or may have as against the other Borrowers
with respect to the Obligations; (2) any right to proceed against the other
Borrowers or any other Person, now or hereafter, for contribution, indemnity,
reimbursement, or any other suretyship rights and claims, whether direct or
indirect, liquidated or contingent, whether arising under express or implied
contract or by operation of law, which such Borrower may now have or hereafter
have as against the other Borrowers with respect to the Obligations; and (3)
any right to proceed or seek recourse against or with respect to any property
or asset of the other Borrowers.

                          (iii)   WITHOUT LIMITING THE GENERALITY OF ANY OTHER
WAIVER OR OTHER PROVISION SET FORTH IN THIS SECTION 11.4, EACH BORROWER HEREBY
ABSOLUTELY, KNOWINGLY, UNCONDITIONALLY, AND EXPRESSLY WAIVES AND AGREES NOT TO
ASSERT ANY AND ALL BENEFITS OR DEFENSES ARISING DIRECTLY OR INDIRECTLY UNDER
ANY ONE OR MORE OF CALIFORNIA CIVIL CODE SECTIONS 2799,

OF THE CALIFORNIA CIVIL CODE.

                          (f)     Each Borrower consents and agrees that,
without notice to or by such Borrower, and without affecting or impairing the
liability of such Borrower hereunder, Foothill may, by action or inaction:

                                  (i)      compromise, settle, extend the
                                           duration or the time for the payment
                                           of, or discharge the performance of,
                                           or may refuse to or otherwise not
                                           enforce the Loan Documents, or any
                                           part thereof, with respect to the
                                           other Borrowers;

                                  (ii)     release the other Borrowers or grant
                                           other indulgences to the other 
                                           Borrowers in respect thereof; or

                                  (iii)    release or substitute any guarantor,
                                           if any, of the Obligations, or
                                           enforce, exchange, release, or waive
                                           any security for the Obligations or
                                           any guaranty of the Obligations, or
                                           any portion thereof.

                          (g)     Foothill shall have the right to seek
recourse against each Borrower to the fullest extent provided for herein, and
no election by Foothill to proceed in one form of action or proceeding, or
against any party, or on any obligation, shall constitute a waiver of
Foothill's right to proceed in any other form of action or proceeding or
against other parties unless Foothill has expressly waived such right in
writing.  Specifically, but without limiting the generality of the foregoing,
no action or proceeding by Foothill under the Loan Documents shall serve to
diminish the liability of any Borrower thereunder except to the extent that
Foothill finally and unconditionally shall have realized indefeasible payment
by such action or proceeding.

                          (h)     The Obligations shall not be considered
indefeasibly paid for purposes of this Section 11.4 unless and until all
payments to Foothill are no longer subject to any right on the part of any
person, including any Borrower, any Borrower as a debtor in possession, or any
trustee (whether appointed pursuant to 11 U.S.C., or otherwise) of any
Borrower's assets to invalidate or set aside such payments or to seek to recoup
the amount of such payments or any portion thereof, or to declare same to be
fraudulent or preferential.  Upon such full and final performance and
indefeasible payment of the Obligations, Foothill shall have no obligation
whatsoever to transfer or assign its interest in the Loan Documents to any
Borrower.  In the event that, for any reason, any portion of such payments to
Foothill is set aside or restored, whether voluntarily or involuntarily, after
the making thereof, then the obligation intended to be satisfied thereby shall
be revived and continued in full force and





                                       48
<PAGE>   54
effect as if said payment or payments had not been made, and each Borrower
shall be liable for the full amount Foothill is required to repay plus any and
all costs and expenses (including attorneys' fees and attorneys' fees incurred
pursuant to 11 U.S.C.) paid by Foothill in connection therewith.

                 Borrowers and each of them warrant and agree that each of the
waivers and consents set forth herein are made after consultation with legal
counsel and with full knowledge of their significance and consequences, with
the understanding that events giving rise to any defense or right waived may
diminish, destroy or otherwise adversely affect rights which Borrowers
otherwise may have against other Borrowers, the Lender Group or others, or
against Collateral.  If any of the waivers or consents herein are determined to
be contrary to any applicable law or public policy, such waivers and consents
shall be effective to the maximum extent permitted by law.

         12.     NOTICES.

                 Unless otherwise provided in this Agreement, all notices or
demands by any party relating to this Agreement or any other Loan Document

                 15.2     SUCCESSORS AND ASSIGNS.  This Agreement shall bind
and inure to the benefit of the respective successors and assigns of each of
the parties; provided, however, that no Borrower may assign this Agreement or

relating to creditors' rights, including provisions of the Bankruptcy Code
relating to fraudulent conveyances, preferences, and other voidable or
recoverable payments of money or transfers of property (collectively, a
"Voidable Transfer"), and if Foothill is required to repay or restore, in whole
or in part, any such Voidable Transfer, or elects to do so upon the reasonable
advice of its counsel, then, as to any such Voidable Transfer, or the amount
thereof that Foothill is required or elects to repay or restore, and as to all
reasonable costs, expenses, and attorneys fees of Foothill related thereto, the
liability of Borrowers or such guarantor automatically shall be revived,
reinstated, and restored and shall exist as though such Voidable Transfer had
never been made.

                 15.9     INTEGRATION.  This Agreement, together with the other
Loan Documents, reflects the entire understanding of the parties with respect
to the transactions

                 3.3      TITLE.  Debtor is the sole and exclusive owner of the
entire and unencumbered right, title, and interest in and to each of the

not to sue third persons;

                 3.4      NOTICE.  Debtor has used and will continue to use
proper statutory notice in connection with its use of each of the patents,
service marks and trademarks;

                 3.5      QUALITY.  Debtor has used and will continue to use

past practices) in the manufacture, sale, and delivery of products and services

including, to the extent applicable, in the operation and maintenance of its
merchandising operations, and will continue to maintain the validity of the

the security interests created hereunder, no authorization, approval, or other
action by, and no notice to or filing with, any governmental authority or

interest hereunder or for the execution, delivery, or performance of this
Agreement by Debtor or for the perfection of or the exercise by Foothill of its
rights hereunder to the Collateral in the United States.

any patent, the provisions of this Agreement shall automatically apply thereto.
Debtor shall give prompt notice in writing to Foothill with respect to any such
new service marks, trademarks or patents, or renewal or extension of any
service mark or trademark registration.  Debtor shall bear any expenses
incurred in connection with future patent applications or service mark or

         5.      LITIGATION AND PROCEEDINGS.

                 Debtor shall commence and diligently prosecute in its own
name, as the real party in interest, for its own benefit, and its own expense,
such suits, administrative proceedings, or other action for infringement or
other damages as are in its reasonable business judgment necessary to protect
the Collateral.  Debtor shall provide to Foothill any information with respect
thereto requested by Foothill.  Foothill shall provide at Debtor's expense all
necessary cooperation in connection with any such suits, proceedings, or
action,

Debtor's becoming aware thereof, Debtor shall notify Foothill of the
institution of, or any adverse determination in, any proceeding in the United
States Patent and Trademark Office, or any United States, state, or foreign
court regarding Debtor's claim of ownership in any of the patents, service
marks or trademarks, its right to apply for the same, or its right to keep and
maintain such patent, service mark or trademark rights.

desirable for the collection of any of the Collateral or otherwise to enforce
Foothill's rights with respect to any of the Collateral and to assign, pledge,
convey, or otherwise transfer title in or dispose of the Collateral to any
person.

         7.      RIGHT TO INSPECT.

                 Debtor grants to Foothill and its employees and agents the
right to visit Debtor's plants and facilities which manufacture, inspect, or
store products sold under any of the patents or trademarks, and to inspect the
products and quality control records relating thereto at reasonable times
during regular business hours.

         8.      EVENTS OF DEFAULT.

                 Any of the following events shall be an Event of Default:

         9.      SPECIFIC REMEDIES.

                 Upon the occurrence of any Event of Default, Foothill shall
have, in addition to, other rights given by law or in this Agreement, the Loan
Agreement, or in any other Loan Document, all of the rights and remedies with
respect to the Collateral of a secured party under the Code, including the
following:

                 9.1      NOTIFICATION.  Foothill may notify licensees to make
royalty payments on license agreements directly to Foothill;

                 9.2      SALE.  Foothill may sell or assign the Collateral and
associated goodwill at public or private sale for such amounts, and at such
time or times as Foothill deems advisable.  Any requirement of reasonable
notice of any disposition of the Collateral shall be satisfied if such notice
is sent to Debtor five days prior to such disposition.  Debtor shall be
credited with the net proceeds of such sale only when they are actually
received by Foothill, and Debtor shall continue to be liable for any deficiency
remaining after the Collateral is sold or collected.  If the sale is to be a
public sale, Foothill shall also give notice of the time and place by
publishing a notice one time at least five days before the date of the sale in
a newspaper of general circulation in the county in which the sale is to be
held.  To the maximum extent permitted by applicable law, Foothill may be the
purchaser of any or all of the Collateral and associated goodwill at any public
sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at
any public sale, to use and apply all or any part of the Obligations as a
credit on account of the purchase price of any collateral payable by Foothill
at such sale.

                          3.1     COPYRIGHTS.  A true and complete schedule
setting forth all federal copyright registrations owned or controlled by Debtor
or licensed to Debtor, together with a summary description and full information
in respect of the filing or issuance thereof and expiration dates is set forth
on Schedule A;

                          3.2     VALIDITY; ENFORCEABILITY.  Each copyright is
valid and enforceable, and Debtor is not presently aware of any past, present,
or prospective claim by any third party that any copyright is invalid or
unenforceable, or that the use of any copyright violates the rights of any
third person, or of any basis for any such claims;

                          3.3     TITLE.  Debtor is the sole and exclusive
owner of the entire and unencumbered right, title, and interest in and to each
copyright and copyright registration, free and clear of any liens, charges, and
encumbrances, including pledges, assignments, licenses, and covenants by Debtor
not to sue third persons;

                          3.4     NOTICE.  Debtor has used and will continue to
use proper statutory notice in connection with its use of each copyright;

                          3.5     PERFECTION OF SECURITY INTEREST.  Except for
the filing of a financing statement with the Secretary of State of California
and filings with the United States Copyright Office necessary to perfect the
security interests created hereunder, no authorization, approval, or other
action by, and no notice to or filing with, any governmental authority or
regulatory body is required either for the grant by Debtor of the security
interest hereunder or for the execution, delivery, or performance of this
Agreement by Debtor or for the perfection of or the exercise by Foothill of its
rights hereunder to the Collateral in the United States.

                 4.       AFTER-ACQUIRED COPYRIGHTS.

                          If Debtor shall obtain rights to any new copyright,
the provisions of this Agreement shall automatically apply thereto.  Debtor
shall give prompt notice in writing to Foothill with respect to any such new
copyright, or renewal or extension of any copyright registration.  Debtor shall
bear any expenses incurred in connection with future copyright registrations.

                 5.       LITIGATION AND PROCEEDINGS.

                          Debtor shall commence and diligently prosecute in its
own name, as the real party in interest, for its own benefit, and its own
expense, such suits, administrative proceedings, or other action for
infringement or other damages as are in its reasonable business judgment
necessary to protect the Collateral.  Debtor shall provide to Foothill any
information with respect thereto requested by Foothill.  Foothill shall provide
at Debtor's expense all necessary cooperation in connection with any such
suits, proceedings, or action, including, without limitation, joining as a
necessary party.  Following Debtor's becoming aware thereof, Debtor shall
notify Foothill of the institution of, or any adverse determination in, any





                                       3

proceeding in the United States Copyright Office, or any United States, state,
or foreign court regarding Debtor's claim of ownership in any copyright, its
right to apply for the same, or its right to keep and maintain such copyright
rights.

                 6.       POWER OF ATTORNEY.

                          Debtor grants Foothill power of attorney, having the
full authority, and in the place of Debtor and in the name of Debtor, from time
to time following an Event of Default in Foothill's discretion, to take any
action and to execute any instrument which Foothill may deem necessary or
advisable to accomplish the purposes of this Agreement, including, without
limitation, as may be subject to the provisions of this Agreement:  to endorse
Debtor's name on all applications, documents, papers, and instruments necessary
for Foothill to use or maintain the Collateral; to ask, demand, collect, sue
for, recover, impound, receive, and give acquittance and receipts for money due
or to become due under or in respect of any of the Collateral; to file any
claims or take any action or institute any proceedings that Foothill may deem
necessary or desirable for the collection of any of the Collateral or otherwise
to enforce Foothill's rights with respect to any of the Collateral and to
assign, pledge, convey, or otherwise transfer title in or dispose of the
Collateral to any person.

                 7.       EVENTS OF DEFAULT.

                          Any of the following events shall be an Event of

occur as defined in the Loan Agreement;

                          7.2     MISREPRESENTATION.  Any representation or
warranty made herein by Debtor or in any document furnished to Foothill by
Debtor under this Agreement is incorrect in any material respect when made or
when reaffirmed; and

                          7.3     BREACH.  Debtor fails to observe or perform
any covenant, condition, or agreement to be observed or performed pursuant to
the terms hereof which materially and adversely affects Foothill.

                 8.       SPECIFIC REMEDIES.

                          Upon the occurrence of any Event of Default, Foothill

Loan Agreement, or in any other Loan Document, all of the rights and remedies
with respect to the Collateral of a secured party under the Code, including the
following:

                          8.2     SALE.  Foothill may sell or assign the
Collateral and associated goodwill at public or private sale for such amounts,
and at such time or times as Foothill deems advisable.  Any requirement of
reasonable notice of any disposition of the Collateral shall be satisfied if
such notice is sent to Debtor five days prior to such disposition.  Debtor
shall be credited with the net proceeds of such sale only when they are
actually received by Foothill, and Debtor shall continue to be liable for any
deficiency remaining after the Collateral is sold or collected.  If the sale is
to be a public sale, Foothill shall also give notice of the time and place by
publishing a notice one time at least five days before the date of the sale in
a newspaper of general circulation in the county in which the sale is to be
held.  To the maximum extent permitted by applicable law, Foothill may be the
purchaser of any or all of the Collateral and associated goodwill at any public
sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at
any public sale, to use and apply all or any part of the Obligations as a
credit on account of the purchase price of any collateral payable by Foothill
at such sale.

                 3.3      TITLE.  Debtor is the sole and exclusive owner of the
entire and unencumbered right, title, and interest in and to each of the
patents, service marks, service mark registrations, trademarks, and trademark

including pledges, assignments, licenses, shop rights, and covenants by Debtor
not to sue third persons;

                 3.4      NOTICE.  Debtor has used and will continue to use
proper statutory notice in connection with its use of each of the patents,
service marks and trademarks;

                 3.5      QUALITY.  Debtor has used and will continue to use
consistent standards of high quality (which may be consistent with Debtor's
past practices) in the manufacture, sale, and delivery of products and services

including, to the extent applicable, in the operation and maintenance of its
merchandising operations, and will continue to maintain the validity of the

rights hereunder to the Collateral in the United States.

         4.      AFTER-ACQUIRED PATENT, SERVICE MARK OR TRADEMARK RIGHTS.

                 If Debtor shall obtain rights to any new service marks,
trademarks, any new patentable inventions or become entitled to the benefit of
any patent application or patent for any reissue, division, or continuation, of
any patent, the provisions of this Agreement shall automatically apply thereto.
Debtor shall give prompt notice in writing to Foothill with respect to any such
new service marks, trademarks or patents, or renewal or extension of any
service mark or trademark registration.  Debtor shall bear any expenses
incurred in connection with future patent applications or service mark or
trademark registrations.

         5.      LITIGATION AND PROCEEDINGS.

                 Debtor shall commence and diligently prosecute in its own
name, as the real party in interest, for its own benefit, and its own expense,

other damages as are in its reasonable business judgment necessary to protect
the Collateral.  Debtor shall provide to Foothill any information with respect
thereto requested by Foothill.  Foothill shall provide at Debtor's expense all

Debtor's becoming aware thereof, Debtor shall notify Foothill of the
institution of, or any adverse determination in, any proceeding in the United
States Patent and Trademark Office, or any United States, state, or foreign
court regarding Debtor's claim of ownership in any of the patents, service
marks or trademarks, its right to apply for the same, or its right to keep and
maintain such patent, service mark or trademark rights.

         6.      POWER OF ATTORNEY.

                 Debtor grants Foothill power of attorney, having the full
authority, and in the place of Debtor and in the name of Debtor, from time to
time following an Event of Default in Foothill's discretion, to take any action
and to execute any instrument which Foothill may deem necessary or advisable to
accomplish the purposes of this Agreement, including, without limitation, as
may be subject to the provisions of this Agreement:  to endorse Debtor's name
on all applications, documents, papers, and instruments necessary for Foothill
to use or maintain the Collateral; to ask, demand, collect, sue for, recover,
impound, receive, and give acquittance and receipts for money due or to become
due under or in respect of any of the Collateral; to file any claims or take
any action or institute any proceedings that Foothill may deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
Foothill's rights with respect to any of the Collateral and to assign, pledge,
convey, or otherwise transfer title in or dispose of the Collateral to any
person.

         7.      RIGHT TO INSPECT.

                 Debtor grants to Foothill and its employees and agents the
right to visit Debtor's plants and facilities which manufacture, inspect, or

products and quality control records relating thereto at reasonable times
during regular business hours.

         8.      EVENTS OF DEFAULT.

         9.      SPECIFIC REMEDIES.

                 Upon the occurrence of any Event of Default, Foothill shall
have, in addition to, other rights given by law or in this Agreement, the Loan
Agreement, or in any other Loan Document, all of the rights and remedies with
respect to the Collateral of a secured party under the Code, including the
following:

                 9.1      NOTIFICATION.  Foothill may notify licensees to make
royalty payments on license agreements directly to Foothill;

                 9.2      SALE.  Foothill may sell or assign the Collateral and
associated goodwill at public or private sale for such amounts, and at such
time or times as Foothill deems advisable.  Any requirement of reasonable
notice of any disposition of the Collateral shall be satisfied if such notice
is sent to Debtor five days prior to such disposition.  Debtor shall be
credited with the net proceeds of such sale only when they are actually
received by Foothill, and Debtor shall continue to be liable for any deficiency
remaining after the Collateral is sold or collected.  If the sale is to be a
public sale, Foothill shall also give notice of the time and place by
publishing a notice one time at least five days before the date of the sale in
a newspaper of general circulation in the county in which the sale is to be
held.  To the maximum extent permitted by applicable law, Foothill may be the
purchaser of any or all of the Collateral and associated goodwill at any public
sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at
any public sale, to use and apply all or any part of the Obligations as a
credit on account of the purchase price of any collateral payable by Foothill
at such sale.

                          Debtor hereby represents, warrants, and covenants
that:





                                       2
<PAGE>   3
                          3.1     COPYRIGHTS.  A true and complete schedule
setting forth all federal copyright registrations owned or controlled by Debtor
or licensed to Debtor, together with a summary description and full information
in respect of the filing or issuance thereof and expiration dates is set forth
on Schedule A;

                          3.2     VALIDITY; ENFORCEABILITY.  Each copyright is
valid and enforceable, and Debtor is not presently aware of any past, present,
or prospective claim by any third party that any copyright is invalid or
unenforceable, or that the use of any copyright violates the rights of any
third person, or of any basis for any such claims;

                          3.3     TITLE.  Debtor is the sole and exclusive
owner of the entire and unencumbered right, title, and interest in and to each
copyright and copyright registration, free and clear of any liens, charges, and
encumbrances, including pledges, assignments, licenses, and covenants by Debtor
not to sue third persons;

                          3.4     NOTICE.  Debtor has used and will continue to
use proper statutory notice in connection with its use of each copyright;

                          3.5     PERFECTION OF SECURITY INTEREST.  Except for
the filing of a financing statement with the Secretary of State of Texas and
filings with the United States Copyright Office necessary to perfect the
security interests created hereunder, no authorization, approval, or other
action by, and no notice to or filing with, any governmental authority or
regulatory body is required either for the grant by Debtor of the security
interest hereunder or for the execution, delivery, or performance of this
Agreement by Debtor or for the perfection of or the exercise by Foothill of its
rights hereunder to the Collateral in the United States.

                 4.       AFTER-ACQUIRED COPYRIGHTS.

                          If Debtor shall obtain rights to any new copyright,
the provisions of this Agreement shall automatically apply thereto.  Debtor
shall give prompt notice in writing to Foothill with respect to any such new
copyright, or renewal or extension of any copyright registration.  Debtor shall
bear any expenses incurred in connection with future copyright registrations.

                 5.       LITIGATION AND PROCEEDINGS.

                          Debtor shall commence and diligently prosecute in its
own name, as the real party in interest, for its own benefit, and its own
expense, such suits, administrative proceedings, or other action for
infringement or other damages as are in its reasonable business judgment
necessary to protect the Collateral.  Debtor shall provide to Foothill any
information with respect thereto requested by Foothill.  Foothill shall provide
at Debtor's expense all necessary cooperation in connection with any such
suits, proceedings, or action, including, without limitation, joining as a
necessary party.  Following Debtor's becoming aware thereof, Debtor shall
notify Foothill of the institution of, or any adverse determination in, any





                                       3

proceeding in the United States Copyright Office, or any United States, state,
or foreign court regarding Debtor's claim of ownership in any copyright, its
right to apply for the same, or its right to keep and maintain such copyright
rights.

                 6.       POWER OF ATTORNEY.

                          Debtor grants Foothill power of attorney, having the

for Foothill to use or maintain the Collateral; to ask, demand, collect, sue
for, recover, impound, receive, and give acquittance and receipts for money due

necessary or desirable for the collection of any of the Collateral or otherwise
to enforce Foothill's rights with respect to any of the Collateral and to
assign, pledge, convey, or otherwise transfer title in or dispose of the
Collateral to any person.

                          8.2     SALE.  Foothill may sell or assign the
Collateral and associated goodwill at public or private sale for such amounts,
and at such time or times as Foothill deems advisable.  Any requirement of
reasonable notice of any disposition of the Collateral shall be satisfied if
such notice is sent to Debtor five days prior to such disposition.  Debtor
shall be credited with the net proceeds of such sale only when they are
actually received by Foothill, and Debtor shall continue to be liable for any
deficiency remaining after the Collateral is sold or collected.  If the sale is
to be a public sale, Foothill shall also give notice of the time and place by
publishing a notice one time at least five days before the date of the sale in
a newspaper of general circulation in the county in which the sale is to be
held.  To the maximum extent permitted by applicable law, Foothill may be the
purchaser of any or all of the Collateral and associated goodwill at any public
sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at
any public sale, to use and apply all or any part of the Obligations as a
credit on account of the purchase price of any collateral payable by Foothill
at such sale.

costs incurred in enforcing any judgment are recoverable as a separate item in
addition to fees and costs incurred in obtaining the judgment and that the

<PAGE>   3
"hereby," "hereunder," and other similar terms refer to this Agreement as a
whole and not to any particular provision of this Agreement.  Any reference
herein to any document includes any and all alterations, amendments,
extensions, modifications, renewals, or supplements thereto or thereof, as
applicable.  Neither this Agreement nor any uncertainty or ambiguity herein
shall be construed or resolved against Foothill or Pledgor, whether under any
rule of construction or otherwise.  On the contrary, this Agreement has been
reviewed by Pledgor, Foothill, and their respective counsel, and shall be
construed and interpreted according to the ordinary meaning of the words used
so as to fairly accomplish the purposes and intentions of Foothill and Pledgor.

                 2.       PLEDGE.  As security for the prompt and complete
payment and performance of the Obligations, Pledgor hereby delivers, pledges,
and grants to Foothill a continuing security interest in all of Pledgor's
now-owned or hereafter-acquired right, title, and interest in and to the
Collateral.  All certificates or instruments representing or evidencing the
Collateral shall be delivered promptly to and held by Foothill pursuant hereto
and shall be in suitable form for transfer or assignment in blank, all in form
and substance satisfactory to Foothill.


                 3.       FURTHER ASSURANCES.  Pledgor agrees that it shall
cooperate with Foothill and shall execute and deliver, or cause to be executed
and delivered, to Foothill all stock powers, proxies, assignments, financing
statements, instruments, and other documents, and shall take all further
action, at the expense of Pledgor, from time to time requested by Foothill, in
order to maintain a continuing, first-priority, perfected security interest in
the Collateral in favor of Foothill, and to enable Foothill to exercise and
enforce its rights and remedies hereunder with respect to the Collateral, and
Pledgor agrees that it shall execute and deliver to Foothill at Foothill's
request any further applications, agreements, documents and instruments, and
shall perform any and all acts deemed necessary by Foothill to carry into
effect the terms, conditions, and provisions of this Agreement and the
transactions connected herewith.  Should Pledgor fail to execute or deliver any
such applications, agreements, documents, financing statements and instruments,
or to perform any such acts, Pledgor acknowledges that Foothill may execute and
deliver the same and perform such acts in the name of Pledgor and on its behalf
as its attorney-in-fact in accordance with Section 13.

                 4.       FOOTHILL'S DUTIES.  Foothill shall not have any
duties with respect to the Collateral other than the duty to use reasonable
care if the Collateral is in its possession.  In accordance with Section 9207
of the Code, Foothill shall be deemed to have used reasonable care if it
observes substantially the same standard of care with respect to the custody or
preservation of the Collateral as it observes with respect to similar assets
owned by Foothill.  Without limiting the generality of the foregoing, Foothill
shall not be under any obligation to take any steps to preserve rights in the
Collateral against any other parties, to sell the same if it threatens to
decline in value, or to exercise any rights represented thereby (including
rights with respect to calls, conversions, exchanges, maturities, or tenders);
provided, however, that Foothill may, at its option, do so, and any and all
expenses incurred in connection therewith shall be for the account of Pledgor.

<PAGE>   4
                 5.       VOTING RIGHTS; DIVIDENDS; ETC.  During the term of
this Agreement, and as long as no Event of Default has occurred and is
continuing:

                          5.1     Pledgor shall be entitled to exercise any and
all voting and other consensual rights pertaining to the Shares or any part
thereof; provided, however, no vote shall be cast or any consent, waiver or
ratification given or any action taken which would violate or be inconsistent
with the terms of this Agreement, the Loan Agreement or any other instrument or
agreement referred to therein or herein, or which could have the effect of
impairing the value of the Collateral or any part thereof or the position or
interest of Foothill therein.

                          5.2     Pledgor shall be entitled to receive and
retain any and all dividends and distributions paid in respect of the Shares;
provided, however, that any and all:

                                  (a)      dividends and distributions paid or
payable other than in cash in respect of, and any and all additional shares or
instruments or other property received, receivable, or otherwise distributed in
respect of, or in exchange for the Shares;

                                  (b)      dividends and distributions paid or
payable in cash in respect of any Shares in connection with a partial or total
liquidation or dissolution, merger, consolidation of the Company, or any
exchange of stock, conveyance of assets, or similar corporate reorganization;
and

                                  (c)      cash paid with respect to, payable,
or otherwise distributed on redemption of, or in exchange for, any Shares, shall
be forthwith delivered to Foothill to hold as Collateral and shall, if received
by Pledgor, be received in trust for the benefit of Foothill, be segregated from
the other property or funds of Pledgor, and be forthwith delivered to Foothill
as Collateral in the same form as so received (with any necessary endorsement),
and, if deemed appropriate by Foothill, Pledgor shall take such actions,
including the actions described in Section 2, as Foothill may require.

                 6.       REPRESENTATIONS, WARRANTIES, AND COVENANTS.  Pledgor
warrants, represents, and covenants that:

                          6.1     Pledgor is a corporation duly organized,
validly existing and in good standing under the laws of Delaware.

                          6.2     The execution, delivery and performance of
this Agreement are within Pledgor's powers, are not in conflict with the terms
of the Certificate of Incorporation or By-Laws or other organizational
agreement or instrument of Pledgor, and will not result in a breach of or
constitute a default under any material contract, obligation, indenture or
other instrument to which Pledgor is a party or by which Pledgor is bound; and
there is no material law, rule or regulation, nor is there any judgment, decree
or order of any court or





                                       4
<PAGE>   5
governmental authority binding on Pledgor which would be contravened by the
execution, delivery, performance or enforcement of this Agreement.

                          6.3     Pledgor has taken all corporate action
necessary to authorize the execution and delivery of this Agreement, and the
consummation of the transactions contemplated hereby and thereby.  Upon its
execution and delivery in accordance with the terms hereof, this Agreement will
constitute legal, valid and binding agreements and obligations of Pledgor,
enforceable against Pledgor in accordance with its terms, except as
enforceability may be limited by bankruptcy, insolvency, and similar laws and
equitable principles affecting the enforcement of creditors' rights generally.

                          6.4     Other than United States and British federal
laws and state and provincial securities laws and rules, there are no
restrictions upon the transfer of any of the Collateral to or by Foothill;
Pledgor is the sole beneficial owner of the Collateral, and Pledgor has the
right to pledge and grant a security interest in or otherwise transfer such
Collateral free of any encumbrances or rights of third parties, except for
Permitted Liens.

                          6.5     All of the Collateral shall remain free from
all liens, claims, encumbrances, and purchase-money or other security interests
except as created hereby.  Pledgor shall not, without Foothill's prior written
consent, sell or otherwise dispose of any of the Collateral.

                          6.6     The execution and delivery of this Agreement,
and the delivery to Foothill of the certificate evidencing the Shares creates a
valid, perfected, and first-priority security interest in the Collateral in
favor of Foothill, and all actions necessary or desirable to such perfection
have been duly taken.

                          6.7     No authorization or other action by, and no
notice to or filing with, any governmental authority or regulatory body is
required either:  (a) for the grant by Pledgor of the security interest granted
hereby or for the execution, delivery, or performance of this Agreement by
Pledgor; (b) for the perfection of or exercise by Foothill of its rights and
remedies hereunder (except as may have been taken by or at the direction of
Pledgor or as may be required in connection with a disposition of the
Collateral by laws affecting the offering and sale of securities generally); or
(c) for the exercise by Foothill of the voting or other rights provided for in
this Agreement or the remedies in respect of the Collateral pursuant to this
Agreement (except as may be required in connection with a disposition of the
Collateral by laws affecting the offering and sale of securities generally) and
any applicable antitrust laws.

                          6.8 The Company presently has issued and outstanding
the following shares which shares are owned by Pledgor:

                                  (a)      250 A Ordinary Shares,

<PAGE>   6
                                  (b)      750 B Ordinary Shares, and

                                  (c)      399,000 Preference Shares.

                          6.9     There are no presently existing Options.

                          6.10    The Shares has been duly and validly issued by
the Company, and are fully paid and nonassessable.

                          6.11    Pledgor has made its own arrangements for
keeping informed of changes or potential changes affecting the Collateral
(including, but not limited to, rights to convert, rights to subscribe, payment
of dividends, reorganization or other exchanges, tender offers, and voting
rights), and Pledgor agrees that Foothill shall not have any responsibility or
liability for informing Pledgor of any such changes or potential changes or for
taking any action or omitting to take any action with respect thereto.

                 7.       SHARE ADJUSTMENTS.  In the event that during the term
of this Agreement, any reclassification, readjustment, or other change is
declared or made in the capital structure of the Company, or any Option is
exercised, all new substituted and additional shares, options, or other
securities, issued or issuable to Pledgor by reason of any such change or
exercise shall be delivered to and held by Foothill under the terms of this
Agreement in the same manner as the Collateral originally pledged hereunder.

                 8.       OPTIONS.  In the event that during the term of this
Agreement Options shall be issued or exercised in connection with the
Collateral, such Options acquired by Pledgor shall be immediately assigned by
Pledgor to Foothill and all new shares or other securities so acquired by
Pledgor shall also be immediately assigned to Foothill to be held under the
terms of this Agreement in the same manner as the Collateral originally pledged
hereunder.

                 9.       CONSENT.  Pledgor hereby consents that, from time to
time, before or after the occurrence or existence of any Event of Default, with
or without notice to or assent from Pledgor, any other security at any time
held by or available to Foothill for any of the Obligations or any other
security at any time held by or available to Foothill of any other person,
firm, or corporation secondarily or otherwise liable for any of the
Obligations, may be exchanged, surrendered, or released and any of the
Obligations may be changed, altered, renewed, extended, continued, surrendered,
compromised, waived, or released, in whole or in part, as Foothill may see fit.
Pledgor shall remain bound under this Agreement notwithstanding any such
exchange, surrender, release, alteration, renewal, extension, continuance,
compromise, waiver, or inaction, or extension of further credit.

                 10.     EVENTS OF DEFAULT.  Any of the following events shall 
be an Event of Default:





                                       6
<PAGE>   7
                 10.1     LOAN AGREEMENT.  An Event of Default shall occur as
defined in the Loan Agreement;

                 10.2     MISREPRESENTATION.  Any representation or warranty
made herein by Pledgor or in any document furnished to Foothill by Pledgor
under this Agreement is incorrect in any material respect when made or when
reaffirmed; and

                 10.3     BREACH.  Pledgor fails to observe or perform any
covenant, condition, or agreement to be observed or performed pursuant to the
terms hereof which materially and adversely affects Foothill.

                 11.      REMEDIES UPON DEFAULT.  Upon the occurrence and
continuance of an Event of Default, Foothill shall have, in addition to any
other rights given by law or in this Agreement, in the Loan Agreement, or in
any other agreement between Foothill and Pledgor, all of the rights and
remedies with respect to the Collateral of a secured party under the Code, and
also shall have, without limitation, the following rights, which Pledgor hereby
agrees to be commercially reasonable:

                          11.1    to transfer all or any part of the Collateral
into the Foothill's name or the name of its nominee or nominees;

                          11.2    all rights of Pledgor to exercise the voting
and other consensual rights that it would otherwise be entitled to exercise
pursuant to Section 5.1 and to receive the dividends and distributions that it
would otherwise be authorized to receive and retain pursuant to Section 5.2
shall, at Foothill's option, cease, and all such rights shall, at Foothill's
option, thereupon become vested in Foothill, and Foothill shall, at its option,
thereupon have the sole right to exercise such voting and other consensual
rights and to receive and hold as Collateral such dividends and interest
payments.  Any payments received by Pledgor contrary to the provisions of this
Section shall be held in trust by Pledgor for the benefit of Foothill, shall be
segregated from other funds of Pledgor, and shall be promptly paid over to
Foothill, with any necessary endorsement;

                          11.3    to vote the Shares (whether or not
transferred into the name of the Foothill), and give all consents, waivers and
ratifications in respect of the Collateral and otherwise act with respect
thereto as though it were the outright owner thereof; PLEDGOR HEREBY
IRREVOCABLY CONSTITUTES AND APPOINTS FOOTHILL THE PROXY AND ATTORNEY-IN-FACT OF
PLEDGOR, COUPLED WITH AN INTEREST, WITH FULL POWER OF SUBSTITUTION TO DO SO;
SUCH PROXY SHALL CONTINUE IN FULL FORCE AND EFFECT AND TERMINATE UPON THE
SOONER TO OCCUR OF: (a) THE INDEFEASIBLE PAYMENT IN FULL OF THE OBLIGATIONS;
AND (b) MARCH 31, 2007.

                          11.4    at any time or from time to time, to sell,
assign and deliver, or grant options to purchase, all or any part of the
Collateral, or any interest therein, at any





                                       7
<PAGE>   8
public or private sale, without demand of performance, advertisement or notice
of intention to sell or of the time or place of sale or adjournment thereof or
to redeem or otherwise (all of which are hereby waived by Pledgor), for cash,
on credit or for other property, for immediate or future delivery without any
assumption of credit risk, and for such price or prices and on such terms as
the Foothill in its absolute discretion may determine; provided, that at least
five days notice of the time and place of any such sale shall be given to
Pledgor.  Foothill shall not be obligated to make any such sale of Collateral
regardless of whether any such notice of sale has therefore been given.
Pledgor hereby waives any other requirement of notice, demand, or advertisement
for sale, to the extent permitted by law.  Pledgor hereby waives and releases
to the fullest extent permitted by law any right or equity of redemption with
respect to the Collateral, whether before or after sale hereunder, and all
rights, if any, of marshalling the Collateral and any other security for the
Obligations or otherwise.  At any such sale, unless prohibited by applicable
law, Foothill may bid for and purchase all or any part of the Collateral so
sold free from any such right or equity of redemption.  Foothill shall not be
liable for failure to collect or realize upon any or all of the Collateral or
for any delay in so doing nor shall Foothill be under any obligation to take
any action whatsoever with regard thereto;

                          11.5    to buy the Collateral, in its own name, or in
the name of a designee or nominee.  Foothill shall have the right to execute
any document or form, in its name or in the name of the Pledgor, that may be
necessary or desirable in connection with such sale of the Collateral.

                          11.6    to sell the Collateral by a private
placement, restricting bidders and prospective purchasers to those who will
represent and agree that they are purchasing for investment only and not for
distribution.  In so doing, Foothill may solicit offers to buy the Collateral,
or any part of it for cash, from a limited number of investors deemed by
Foothill, in its reasonable credit judgment, to be responsible parties who
might be interested in purchasing the Collateral.  If Foothill shall solicit
such offers from not less than four (4) such investors, then the acceptance by
Foothill of the highest offer obtained therefor shall be deemed to be a
commercial reasonable method of disposition of such Collateral, even though the
sales price established and/or obtained may be substantially less than the
price that would be obtained pursuant to a public offering.  Notwithstanding
the foregoing, should Foothill determine that, prior to any public offering of
any securities contained in the Collateral, such securities should be
registered under the '33 Act and/or registered or qualified under any other
British or United States federal, provincial or state law, and that such
registration and/or qualification is not practical, Pledgor agrees that it will
be commercially reasonable if a private sale is arranged so as to avoid a
public offering even if offers are solicited from fewer than four investors,
and even though the sales price established and/or obtained may be
substantially less than the price that would be obtained pursuant to a public
offering.

                 12.      INDEFEASIBLE PAYMENT.  The Obligations shall not be
considered indefeasibly paid for purposes of this Agreement unless and until
all payments to Foothill are no longer subject to any right on the part of any
Person, including Pledgor, Pledgor as a





                                       8
<PAGE>   9
debtor in possession, or any trustee (whether appointed under the Bankruptcy
Code or otherwise) of Pledgor or any of Pledgor's Assets, to invalidate or set
aside such payments or to seek to recoup the amount of such payments or any
portion thereof, or to declare same to be fraudulent or preferential.  In the
event that, for any reason, any portion of such payments to Foothill is set
aside or restored, whether voluntarily or involuntarily, after the making
thereof, then the obligation intended to be satisfied thereby shall be revived
and continued in full force and effect as if said payment or payments had not
been made.

                 13.      FOOTHILL AS PLEDGOR'S ATTORNEY-IN FACT.  Pledgor
hereby irrevocably appoints Foothill as its attorney-in-fact to arrange for the
transfer, at any time after the occurrence and during the continuance of an
Event of Default, of the Collateral on the books of the Company to the name of
Foothill or to the name of Foothill's nominee.  Pledgor further authorizes
Foothill to perform any and all acts which Foothill deems necessary for the
protection and preservation of the Collateral or of the value of Foothill's
security interest therein, including but not limited to receiving income
thereon as additional security hereunder, all at Pledgor's expense, and Pledgor
agrees to repay Foothill promptly upon demand any amounts expended hereunder by
Foothill, together with interest thereon.  Pledgor further grants to Foothill a
power of attorney coupled with an interest to execute all agreements, forms,
applications, documents and instruments and to take all actions and do all
things as could be executed, taken, or done by Pledgor in connection with the
protection and preservation of the Collateral or this Agreement if Pledgor does
not timely do so.  This power of attorney is irrevocable and coupled with an
interest, and authorizes Foothill to act for Pledgor in connection with the
matters described herein without notice to or demand upon Pledgor.

                 14.      GENERAL PROVISIONS.

                          14.1    CUMULATIVE REMEDIES; NO PRIOR RECOURSE TO
COLLATERAL.  The enumeration herein of Foothill's rights and remedies is not
intended to be exclusive, and such rights and remedies are in addition to and
not by way of limitation of any other rights or remedies that the Foothill may
have under the Loan Agreement, the Loan Documents, the Code, or other
applicable law.  Foothill shall have the right, in its sole discretion, to
determine which rights and remedies are to be exercised and in which order.
The exercise of one right or remedy shall not preclude the exercise of any
others, all of which shall be cumulative.

                          14.2    NO IMPLIED WAIVERS.  No act, failure, or
delay by Foothill shall constitute a waiver of any of its rights and remedies.
No single or partial waiver by Foothill of any provision of this Agreement or
of a breach or default hereunder, or thereunder, or of any right or remedy
which Foothill may have, shall operate as a waiver of any other provision,
breach, default, right, or remedy or of the same provision, breach, default,
right, or remedy on a future occasion.  No waiver by Foothill shall affect its
rights to require strict performance of this Agreement.





                                       9
<PAGE>   10
                          14.3    NOTICES.  All notices or demands by any party
hereto to the other party and relating to this Agreement shall be sent in
accordance with the terms of Section 12 of the Loan Agreement.

                          14.4    SUCCESSORS AND ASSIGNS.  This Agreement shall
bind the successors and assigns of Pledgor, and shall inure to the benefit of
the successors and assigns of Foothill; provided, however, that Pledgor may not
assign this Agreement nor delegate any of its duties hereunder without
Foothill's prior written consent and any prohibited assignment shall be
absolutely void.  Foothill may assign this Agreement and its rights and duties
hereunder and no consent or approval by Pledgor is required in connection with
any such assignment.  Foothill reserves the right to sell, assign, transfer,
negotiate, or grant participations in all or any part of, or any interest in
Foothill's rights and benefits hereunder.

                          14.5    SECTION HEADINGS.  Headings and numbers have
been set forth herein for convenience only.  Unless the contrary is compelled
by the context, everything contained in each section applies equally to this
entire Agreement.

                          14.6    AMENDMENTS IN WRITING.  This Agreement cannot
be changed or terminated orally, but only by a writing signed by each party
hereto.  All prior agreements, understandings, representations, warranties, and
negotiations, if any, are merged into this Agreement.

                          14.7    COUNTERPARTS; TELEFACSIMILE EXECUTION.  This
Agreement may be executed in any number of counterparts and by different
parties on separate counterparts, each of which, when executed and delivered,
shall be deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Agreement.  Delivery of an executed counterpart
of this Agreement by telefacsimile shall be equally as effective as delivery of
a manually executed counterpart of this Agreement.  Any party delivering an
executed counterpart of this Agreement by telefacsimile also shall deliver a
manually executed counterpart of this Agreement but the failure to deliver a
manually executed counterpart shall not affect the validity, enforceability,
and binding effect of this Agreement.

                          14.8    TERMINATION BY FOOTHILL.  After termination
of the Loan Agreement and when Foothill has received payment and performance,
in full, of the Obligations, Foothill shall execute and deliver to Pledgor a
termination of all of the security interests granted by Pledgor hereunder and,
to the extent they have been delivered to Foothill and not disposed of in
accordance with this Agreement, certificates evidencing the Share.

                          14.9    GOVERNING LAW; SEVERABILITY OF PROVISIONS.
This Agreement shall be deemed to have been made in the State of California and
the validity, enforceability, construction, interpretation and enforcement of
this Agreement and the rights of the parties hereto shall be determined under,
governed by and construed in accordance with the laws of the State of
California without regard to the principles of conflicts of law; provided,
however, the respective rights of the parties hereto in the Collateral,
including voting the Shares,





                                       10
<PAGE>   11
transfer of the Shares and proxy rights, shall be governed by the corporate
laws of the State of California and England, as applicable, to the extent
either such law is applicable to such rights.  If any provision of this
Agreement or its exhibits shall be determined to be invalid, void or illegal,
such provision shall be construed and amended in a manner which would permit
its enforcement, but in no event shall such provision affect, impair or
invalidate any other provision hereof.

                          14.10   JURISDICTION AND VENUE; WAIVER OF JURY TRIAL.
THE PARTIES HERETO AGREE THAT ALL ACTIONS OR PROCEEDINGS ARISING IN CONNECTION
WITH THIS AGREEMENT SHALL BE TRIED AND LITIGATED ONLY IN THE STATE OR FEDERAL
COURT LOCATED IN THE COUNTY OF LOS ANGELES, STATE OF CALIFORNIA.  THE PARTIES
HERETO HEREBY EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND,
ACTION, CAUSE OF ACTION OR PROCEEDING ARISING UNDER OR WITH RESPECT TO OR IN
ANY WAY RELATED TO THIS AGREEMENT.  THE PARTIES HERETO MAY FILE AN ORIGINAL
COUNTERPART OR A COPY OF THIS SECTION OF THE AGREEMENT WITH ANY COURT AS
WRITTEN EVIDENCE OF THE CONSENT OF THE OTHER PARTY HERETO TO THE WAIVER OF ITS
RIGHT TO TRIAL BY JURY.

                 IN WITNESS WHEREOF, the parties have executed this Agreement
on the date first written above.

                          (i)     A true and complete schedule setting forth
         all federal and state trademark and service mark registrations owned
         or controlled by Debtor or licensed to Debtor, together with a summary
         description and full information in respect of the filing or issuance
         thereof and expiration dates is set forth on Schedule A;

                          (ii)    A true and complete schedule setting forth

         Schedule B;

                 3.2      VALIDITY; ENFORCEABILITY.  Each of the patents,
service marks and trademarks is valid and enforceable, and Debtor is not
presently aware of any past, present, or prospective claim by any third party
that any of the patents, service marks or trademarks





                                        3
<PAGE>   4
are invalid or unenforceable, or that the use of any patents, service marks or
trademarks violates the rights of any third person, or of any basis for any
such claims;

                 3.3      TITLE.  Debtor is the sole and exclusive owner of the
entire and unencumbered right, title, and interest in and to each of the
patents, service marks, service mark registrations, trademarks, and trademark
registrations, free and clear of any liens, charges, and encumbrances,
including pledges, assignments, licenses, shop rights, and covenants by Debtor
not to sue third persons;

                 3.4      NOTICE.  Debtor has used and will continue to use
proper statutory notice in connection with its use of each of the patents,
service marks and trademarks;

                 3.5      QUALITY.  Debtor has used and will continue to use
consistent standards of high quality (which may be consistent with Debtor's
past practices) in the manufacture, sale, and delivery of products and services
sold or delivered under or in connection with the service marks and trademarks,
including, to the extent applicable, in the operation and maintenance of its
merchandising operations, and will continue to maintain the validity of the
service marks and trademarks;

                 3.6      PERFECTION OF SECURITY INTEREST.  Except for the
filing of a financing statement with the Secretary of State of Massachusetts
and filings with the United States Patent and Trademark Office necessary to
perfect the security interests created hereunder, no authorization, approval,
or other action by, and no notice to or filing with, any governmental authority
or regulatory body is required either for the grant by Debtor of the security
interest hereunder or for the execution, delivery, or performance of this
Agreement by Debtor or for the perfection of or the exercise by Foothill of its
rights hereunder to the Collateral in the United States.

         4.      AFTER-ACQUIRED PATENT, SERVICE MARK OR TRADEMARK RIGHTS.

                 If Debtor shall obtain rights to any new service marks,
trademarks, any new patentable inventions or become entitled to the benefit of
any patent application or patent for any reissue, division, or continuation, of
any patent, the provisions of this Agreement shall automatically apply thereto.
Debtor shall give prompt notice in writing to Foothill with respect to any such
new service marks, trademarks or patents, or renewal or extension of any
service mark or trademark registration.  Debtor shall bear any expenses
incurred in connection with future patent applications or service mark or
trademark registrations.

         5.      LITIGATION AND PROCEEDINGS.

                 Debtor shall commence and diligently prosecute in its own
name, as the real party in interest, for its own benefit, and its own expense,
such suits, administrative proceedings, or other action for infringement or
other damages as are in its reasonable





                                        4
<PAGE>   5
business judgment necessary to protect the Collateral.  Debtor shall provide to
Foothill any information with respect thereto requested by Foothill.  Foothill
shall provide at Debtor's expense all necessary cooperation in connection with
any such suits, proceedings, or action, including, without limitation, joining
as a necessary party.  Following Debtor's becoming aware thereof, Debtor shall
notify Foothill of the institution of, or any adverse determination in, any
proceeding in the United States Patent and Trademark Office, or any United
States, state, or foreign court regarding Debtor's claim of ownership in any of
the patents, service marks or trademarks, its right to apply for the same, or
its right to keep and maintain such patent, service mark or trademark rights.

         6.      POWER OF ATTORNEY.

                 Debtor grants Foothill power of attorney, having the full
authority, and in the place of Debtor and in the name of Debtor, from time to
time following an Event of Default in Foothill's discretion, to take any action
and to execute any instrument which Foothill may deem necessary or advisable to
accomplish the purposes of this Agreement, including, without limitation, as
may be subject to the provisions of this Agreement:  to endorse Debtor's name
on all applications, documents, papers, and instruments necessary for Foothill
to use or maintain the Collateral; to ask, demand, collect, sue for, recover,
impound, receive, and give acquittance and receipts for money due or to become
due under or in respect of any of the Collateral; to file any claims or take
any action or institute any proceedings that Foothill may deem necessary or
desirable for the collection of any of the Collateral or otherwise to enforce
Foothill's rights with respect to any of the Collateral and to assign, pledge,
convey, or otherwise transfer title in or dispose of the Collateral to any
person.

         7.      RIGHT TO INSPECT.

                 Debtor grants to Foothill and its employees and agents the
right to visit Debtor's plants and facilities which manufacture, inspect, or
store products sold under any of the patents or trademarks, and to inspect the
products and quality control records relating thereto at reasonable times
during regular business hours.

         8.      EVENTS OF DEFAULT.

                 Any of the following events shall be an Event of Default:

                 8.1      LOAN AGREEMENT.  An Event of Default shall occur as
defined in the Loan Agreement;

                 8.2      MISREPRESENTATION.  Any representation or warranty
made herein by Debtor or in any document furnished to Foothill by Debtor under
this Agreement is incorrect in any material respect when made or when
reaffirmed; and





                                        5
<PAGE>   6
                 8.3      BREACH.  Debtor fails to observe or perform any
covenant, condition, or agreement to be observed or performed pursuant to the
terms hereof which materially and adversely affects Foothill.

         9.      SPECIFIC REMEDIES.

                 Upon the occurrence of any Event of Default, Foothill shall
have, in addition to, other rights given by law or in this Agreement, the Loan
Agreement, or in any other Loan Document, all of the rights and remedies with
respect to the Collateral of a secured party under the Code, including the
following:

                 9.1      NOTIFICATION.  Foothill may notify licensees to make
royalty payments on license agreements directly to Foothill;

                 9.2      SALE.  Foothill may sell or assign the Collateral and
associated goodwill at public or private sale for such amounts, and at such
time or times as Foothill deems advisable.  Any requirement of reasonable
notice of any disposition of the Collateral shall be satisfied if such notice
is sent to Debtor five days prior to such disposition.  Debtor shall be
credited with the net proceeds of such sale only when they are actually
received by Foothill, and Debtor shall continue to be liable for any deficiency
remaining after the Collateral is sold or collected.  If the sale is to be a
public sale, Foothill shall also give notice of the time and place by
publishing a notice one time at least five days before the date of the sale in
a newspaper of general circulation in the county in which the sale is to be
held.  To the maximum extent permitted by applicable law, Foothill may be the
purchaser of any or all of the Collateral and associated goodwill at any public
sale and shall be entitled, for the purpose of bidding and making settlement or
payment of the purchase price for all or any portion of the Collateral sold at
any public sale, to use and apply all or any part of the Obligations as a
credit on account of the purchase price of any collateral payable by Foothill
at such sale.

parties on separate counterparts, each of which, when executed and delivered,
shall be deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Agreement.  Delivery of an executed counterpart
of this Agreement by telefacsimile shall be equally as effective as delivery of

and binding effect of this Agreement.

preparations for the consultations concerning any such matters).  The foregoing
shall not be construed to limit any other provisions of this Agreement or the
Loan Documents regarding costs and expenses to be paid by Debtor.  The parties
agree that reasonable attorneys' and paralegals' fees and costs incurred in
enforcing any judgment are recoverable as a separate item in addition to fees
and costs incurred in obtaining the judgment and that the recovery of such
attorneys' and paralegals' fees and costs is intended to survive any judgment,
and is not to be deemed merged into any judgment.

                 11.9     NOTICES.  Except as otherwise provided herein, all
notices, demands, and requests that either party is required or elects to give
to the other shall be in writing and shall be governed by the provisions of
