                             ECO SOIL SYSTEMS, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

1.   BASIS OF PRESENTATION

     The accompanying unaudited consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all information and footnotes
required by generally accepted accounting principles for complete financial
statements. In the opinion of Eco Soil Systems, Inc. (the "Company"), all
adjustments, consisting only of normal recurring adjustments, necessary for the
fair statement of the results for the three-month and six-month periods ended
June 30, 1999 and 1998 have been made. The results of operations for the
three-month and six-month periods ended June 30, 1999 are not necessarily
indicative of the results to be expected for the full fiscal year. For further
information, refer to the audited financial statements and notes thereto
included in the Company's Annual Report on Form 10-K for the fiscal year ended
December 31, 1998.

2.   NET INCOME/(LOSS) PER SHARE

     In accordance with Financial Accounting Standards Board Statement No. 128,
"Earnings per share" ("SFAS 128") basic earnings per share is calculated
by dividing net income by the weighted average number of common shares
outstanding for the period. Diluted earnings per share reflects the potential
dilution of securities that could share in the earnings of the Company, such
as common stock which may be issuable upon exercise of outstanding common
stock options and warrants. These shares are excluded when their effects are
antidilutive.

3.   SEGMENT INFORMATION

     For purposes of analyzing and understanding the financial statements,
the Company's operations have been classified into the following business
segments:

     TURF PARTNERS: This segment enters into contracts with golf courses or
turf maintenance service businesses, or distributors which sell to those
end-user markets to manage the health and productivity of their soil during
the golf season. These contracts require the Company to perform a
comprehensive soil analysis at the beginning of the season, develop a
treatment regimen, install the Company's proprietary system at the customers
site, and provide the microbials throughout the season. This segment also
wholesales and distributes a wide range of traditional chemical and turf
maintenance products and golf course supplies to the above mentioned market.


                                        6
<PAGE>

     AGRICULTURAL SUPPLY: This segment enters into contracts with agricultural
growers to manage the health and productivity of their soil during the course of
the growing season, which requires the Company to perform a comprehensive soil
analysis at the beginning of the season, develop a treatment regimen, install
the Company's proprietary BioJect system at the customer's site, and provide the
microbials and other soil additive products for the customer to use throughout
the season. This segment also distributes a wide range of irrigation and other
agricultural supplies to growers. In 1998, the Company actively commenced its
soil maintenance service business and acquired several distributors or
irrigation and other agricultural supplies, and therefore created this business
segment. Prior to 1998, agricultural operations were insignificant and were not
considered to be a separate segment.

4.   LEGAL SETTLEMENT

     In November 1998, the Company executed a term sheet with the Palladin
Group, L.P. ("Palladin") concerning negotiations for a possible investment by
Palladin in certain new classes of securities of the Company which, at the
time, the Company was considering issuing to a certain fund managed by
Palladin. The Company subsequently terminated the negotiations in December
1998. An affiliate of Palladin, Halifax Fund, L.P. ("Halifax"), filed a
lawsuit on or about March 19, 1999 in San Diego Superior Court alleging that
the termination violated duties owed by the Company to Halifax under the term
sheet. The lawsuit sought compensatory damages of approximately $2.6 million
and punitive damages of approximately $12.0 million. In July 1999, the
Company executed Settlement and Release Agreements with Halifax Fund, L.P.,
Palladin Group, L.P., Granite Financial Group, Inc., and Midori Capital
Corporation. These agreements mutually release and discharge all claims
arising from this litigation. The settlement required the Company to pay
termination charges and attorney's fees of $198,000.

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

         Certain statements contained in this Management's Discussion and
Analysis that are not related to historical results are forward looking
statements. Actual results may differ materially from those projected or implied
in the forward statements. Further, certain forward looking statements are based
upon assumptions of future events, which may not prove to be accurate. These
forward looking statements involve risks and uncertainties including but not
limited to those referred to below. See "Item 5. Other Information.
Factors That Could Affect Future Performance."

         This information should be read in conjunction with the financial
statements and notes thereto included in Item 1 of this report for the quarter
ended June 30, 1999. Additionally, the financial statements and notes thereto
and Management's Discussion and Analysis in the Company's Annual Report on Form
10-K for the year ended December 31, 1998 will provide additional information.

         In addition to other endeavors, the Company develops, markets and
sells proprietary biological and traditional chemical products to two
principal segments: The turf and golf management market ("Turf Partners") and
the agricultural and crop market ("Ag Supply").

SECOND QUARTER ENDED JUNE 30, 1999 COMPARED TO SECOND QUARTER ENDED JUNE 30,
1998

REVENUES

         For the second quarter of 1999, revenues were $40.7 million, an
increase of 51% versus $26.9 million for the second quarter 1998. The increase
in revenues reflects an increase in both Turf Partners and Ag Supply revenues.

         For the second quarter of 1999, Turf Partners revenues were $34.2
million, an increase of 65% versus $20.7 million for the second quarter 1998.
The increase in Turf Partners sales occurred in all three operating regions of
the U.S. Proprietary sales for Turf Partners remained consistent during the
second quarter of 1999 and 1998 at $2.1 million, while distributed sales
increased to $32.1 million in the second quarter 1999 from $18.6 million in the
second quarter of 1998. The increase in distributed revenue is due to the
expansion of the Company's turf business. During the second quarter of 1999,
Turf Partners completed the integration of the sales force assumed from the
Scott's Company in December 1998 and completed the stocking of several new
warehouses and the realignment of its distribution networks.

         For the second quarter of 1999, Ag Supply revenues were $6.5 million,
an increase of 6%, versus $6.2 million for the second quarter of 1998. Ag Supply
revenues were affected favorably by the acquisitions of Ag Supply de Mexico,
Yuma Sprinkler & Pipe Supply and Riegomex S.A. de C.V. in June 1998. These
acquisitions enabled the Company to expand proprietary sales in Mexico and the
U.S. to $638,000 in the second quarter of 1999 compared to $54,000 in the second
quarter of 1998. Distributed sales for the Ag Supply division decreased to $5.9
million in the second quarter of 1999 from $6.1 million in the second quarter of
1998.

GROSS PROFIT

          For the second quarter of 1999, the Company's gross profit was $11.2
million, an increase of 45% versus $7.7 million for the second quarter of 1998.
The increase in gross profit was due to the increase in both Turf Partners and
Ag Supply revenues. For the second quarter of 1999, the Company's gross margin
was 27% versus 29% during the second quarter of 1998. The decrease in gross
margin was due to the mix of proprietary and distributed sales during the
quarter. Proprietary sales, which carry higher gross margins than distributed
sales, did not grow proportionately to distributed sales during the second
quarter of 1999.

          For the second quarter of 1999, the gross profit on Turf Partners
sales was $8.7 million, an increase of 43% versus $6.1 million during the second
quarter of 1998. The increase in gross profit on Turf Partners sales is directly
related to the increase in revenue, as previously discussed. For the second
quarter of 1999, the gross margin on Turf Partners products was 26% versus 29%
during the second quarter of 1998. The decrease in gross margin on Turf Partners
sales was due to a change in the product mix.

         For the second quarter of 1999, the gross profit on Ag Supply sales was
$2.5 million, compared to $1.6 million during the second quarter of 1998. The
increase in gross profit on Ag Supply sales was directly related to the increase
in revenue. For the second quarter of 1999, the gross margin on Ag Supply
products was 38% versus 26% during the second quarter of 1998. The increase in
gross margin on Ag Supply sales was due to a change in the product mix.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE

          For the second quarter of 1999, selling, general and administrative
("SG&A") expense was $8.7 million, an increase of 53% versus $5.7 million during
the second quarter of 1998. The increase in SG&A expense was primarily due to
additional overhead costs associated with the acquisition of Agricultural Supply
in April 1998 and Ag Supply de Mexico, Yuma Sprinkler and Pipe Supply and
Riegomex in June 1998. SG&A expense as a percentage of sales remained consistent
at 21% for the second quarter of 1999 and 1998.

RESEARCH AND DEVELOPMENT EXPENSE

          For the second quarter of 1999, research and development ("R&D")
expense was $159,000, an increase of 134% versus $68,000 during the second
quarter of 1998. The increase in R & D expense was due to ongoing analysis and
testing of products for the Ag Supply and Turf Partners markets.

INTEREST EXPENSE

         For the second quarter of 1999, interest expense was $796,000, an
increase of 225% versus $245,000 for the second quarter of 1998. The increase in
interest expense reflects an increase in the amount of debt outstanding and
amortization of debt offering cost.

AMORTIZATION EXPENSE

         For the second quarter of 1999, amortization expense was $284,000, an
increase of 3% versus $275,000 for the second quarter of 1998. The increase in
amortization expense is due to an increase in the Company's goodwill directly
related to the Company's 1998 acquisitions, offset by $46,000 decrease of
amortization expense related to Turf Products and Turf Makers goodwill, written
off in December 1998.

NET INCOME

         For the second quarter of 1999, net income was $1.1 million or $.06 per
share versus net income of $1.6 million or $.08 per share during the second
quarter of 1998. During the second quarter of 1999, the Company incurred
$198,000 of expense in connection with a litigation settlement. See "Item 1.
Legal Proceedings."

SIX MONTHS ENDED JUNE 30, 1999 COMPARED TO SIX MONTHS ENDED JUNE 30, 1998

REVENUES

         For the first six months of 1999, revenues were $57.9 million, an
increase of 64% versus $35.3 million for the first six months of 1998. The
increase in revenues reflects an increase in both Turf Partners and Ag Supply
revenues.

         For the first six months of 1999, Turf Partners revenues were $45.8
million, an increase of 57% versus $29.1 million for the first six months of
1998. The increase in Turf Partners revenues occurred in all three operating
regions of the U.S. Proprietary sales for Turf Partners decreased to $2.4
million during the first six months of 1999 from $3.5 million during the
first six months of 1998. The decrease in proprietary sales was due to a
decrease in BioJect usage as a result of the following: (i) our fall 1998
reorganization impaired sales momentum, (ii) integration of the sales force
assumed from the Scotts Company, (iii) new FreshPack programs taxed our sales
force, while providing customer a cheaper alternative to the BioJect, (iv)
long term customers grew tired waiting on EPA and additional biocontrol
products, (v) customers believed their improved turf, resulting from several
seasons of BioJect programs, could manage without a 1999 program. Distributed
sales increased to $43.4 million in the first six months of 1999 from $25.6
million in the first six months of 1998.

         For the first six months of 1999, Ag Supply revenues were $12.1
million, an increase of 96%, versus $6.2 million for the first six months of
1998. Ag Supply revenues were affected favorably by the acquisitions of
Agricultural Supply, Inc. in April 1998 and Yuma Sprinkler & Pipe Supply, and
Riegomex S.A. de C.V. in June 1998. These acquisitions enabled the Company to
expand proprietary sales in Mexico and the U.S. to $837,000 during the first six
months of 1999 compared to $61,000 in the first six months of 1998. Distributed
sales for the Ag Supply division increased to $11.3 million in the first six
months of 1999 from $6.1 million in the first six months of 1998 due to the 1998
acquisitions mentioned above.

GROSS PROFIT

         For the first six months of 1999, the Company's gross profit was
$15.1 million, an increase of 45% versus $10.4 million for the first six
months of 1998. The increase in gross profit was due to the increase in both
Turf Partners and Ag Supply revenues. For the first six months of 1999, the
Company's gross margin was 26% versus 30% for the first six months of 1998.
The decrease in gross margin was due to the mix of proprietary and
distributed sales during the first six months of 1999. Proprietary sales,
which carry higher gross margins than distributed sales, did not grow
proportionately to distributed sales during the first six months of 1999.

         For the first six months of 1999, the gross profit on Turf Partners
sales was $11.1 million, an increase of 26% versus $8.8 million during the
first six months of 1998. The increase in the gross profit on Turf Partners
sales is directly related to the increase in revenue. For the first six
months of 1999, the

                                       10

<PAGE>

gross margin on Turf Partners products was 24% versus 30% during first six
months of 1998. The decrease in gross margin on Turf Partners sales was due
to a change in the product mix.

         For the first six months of 1999, the gross profit on Ag Supply sales
was $4.0 million, an increase of 145%, compared to $1.6 million during the first
six months of 1998. The increase in the gross profit on Ag Supply sales is
directly related to the increase in revenue, as previously discussed. For the
first six months of 1999, the gross margin on Ag Supply products was 33% versus
26% during the first six months of 1998. The increase in gross margin on Ag
Supply sales was due to a change in the product mix.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSE

         For the first six months of 1999, SG&A expense was $16.4 million, an
increase of 68% versus $9.8 million during the first six months of 1998. The
increase in SG&A expense was primarily due to additional overhead costs
associated with the previously discussed acquisitions. SG&A expense as a
percentage of sales remained consistent at 28%, for the first six months of 1999
and 1998.

RESEARCH AND DEVELOPMENT

         For the first six months of 1999, R&D expense was $252,000, an increase
of 50% versus $168,000 during the first six months of 1998. The increase in R&D
expense was due to ongoing analysis and testing of products for the Ag Supply
and golf markets.

INTEREST EXPENSE

         For the first six months of 1999 interest expense was $1.5 million, an
increase of 343% versus $340,000 during the first six months of 1998. The
increase in interest expense reflects an increase in the amount of debt
outstanding, and amortization of debt offering cost.

AMORTIZATION EXPENSE

         For the first six months of 1999, amortization expense was $593,000, an
increase of 29% versus $458,000 during the first six months of 1998. The
increase in amortization expense is due to an increase in the Company's goodwill
directly related to the previously discussed acquisitions, offset by a $92,000
decrease in amortization expense related to Turf Products and Turf Makers
goodwill written off in December 1998.

NET INCOME

     For the six months ended June 30, 1999 net loss was $3.7 million or $.22
per share versus net income of $133,000 or $.01 per share for the six months
ended June 30, 1998. During the six months ended June 30, 1999, the Company
incurred $198,000 of expense in connection with a litigation settlement. See
"Item 1. Legal Proceedings."

LIQUIDITY AND CAPITAL RESOURCES

         The Company has financed its operations from revenues from sales of its
products, sales of its Common Stock, borrowing from its principal shareholders
and bank financing. The Company's operating and investing activities used cash
of $1.9 million during the first six months of 1999 and $7.8 million during the
first six months of 1998.

                                       11

<PAGE>

         On June 30, 1999, the Company's wholly owned subsidiary, Turf Partners,
Inc., entered into a $25 million line of credit with Coast Business Credit. In
addition, the Company's wholly owned subsidiary Agricultural Supply, Inc.
entered into a $10 million line of credit with First National Bank. For
additional information on these lines of credit see "Item 5. Other Information -
Recent Developments."

         On July 31, 1999, the Company obtained a $2.5 million, two-year term
loan from Coast Business Credit. The term loan bears interest at Coast's
prime rate plus 2.25%, payable monthly. One third of the principal must be
repaid in level monthly payments during the second year of the term. The term
loan is secured by substantially all of the assets of the parent company, and
has been guaranteed by Turf Partners. The Company issued a warrant to
purchase 50,000 shares of common stock at an exercise price of $7.81 per
share to Coast in connection with the closing of the term loan transaction.

         The Company intends to fund its future operations and growth through a
combination of product revenues, borrowings available under the line of credit,
and public or private debt or equity financing. However, there can be no
assurance that such financing alternatives will be available under favorable
terms, if at all. The Company believes that it has sufficient resources to
finance its operations and future growth for at least the next twelve months.

YEAR 2000

         Many currently installed computer systems are coded to accept only two
digit entries in the date code field. These date code fields need to be modified
or upgraded to accept four digit entries to distinguish 21st century dates from
20th century dates. Many organizations are expending significant resources to
modify or upgrade their computer systems for such "Year 2000" compliance. We
presently believe that, with modifications to existing software and conversions
to new software, the Year 2000 problem can be mitigated. However, if such
modifications and conversions are not made, or are not timely completed, the
Year 2000 problem could have a material impact on our operations.

         The Year 2000 issue affects our internal systems, including
information technology ("IT") and non-IT systems. We are in the process of
upgrading our existing computer software and IT systems and recognize the
need to ensure our operations will not be adversely impacted by Year 2000
software failures. We rely upon microprocessor-based personal computers and
commercially available applications software. In addition, in the ordinary
course of our product development efforts, we have designed our current
proprietary equipment, consisting of hardware and software, including the
BioJect system itself, to be Year 2000 ready. We are also reviewing our
utility systems (heat, light, telephones, etc.) and other non-IT systems for
the impact of Year 2000. Additionally, should we undertake future
acquisitions, the Year 2000 risks that affect us can be expected to similarly
affect such potential acquisition candidates. We intend to review the systems
of all potential acquisitions for Year 2000 compliance. However, the failure
to correct a material Year 2000 problem either within the Company, within a
vendor or supplier or within a potential acquisition candidate could result
in an interruption in, or a failure of, certain normal business activities or
operations. Such interruptions or failures could materially adversely affect
our business, operating results and financial condition.

         We depend on smooth and timely interactions with our vendors, customers
and other third parties. Any unexpected costs or disruption in the operations or
activities of such vendors, customers or other third parties as a result of Year
2000 compliance issues within such entities could materially adversely affect
our business, operating results or financial condition. The Company intends to
take continuous steps to identify Year 2000 problems related to its vendors and
to formulate a system of working with key third-parties, including financial
institutions and utility-providers, to understand their ability to continue
providing services and products through the change to Year 2000.

         The cost of our Year 2000 compliance assessment and upgrade is being
funded from current operations. The cost to us of our Year 2000 identifications,
assessment, remediation and testing efforts, as well as costs we currently
expect to be incurred with respect to Year 2000 issues of third parties, is
expected to be approximately

                                       12

<PAGE>

$20,000. We will continue to consider the likelihood of a material business
interruption due to the Year 2000 issue and, if necessary, implement
appropriate contingency plans. A contingency plan has not been developed for
dealing with the most reasonably likely worst case scenario, and such
scenario has not yet been clearly identified. Since we have adopted a plan to
address these Year 2000 issues, we have not developed a comprehensive
contingency plan should Year 2000 issues fail to be addressed successfully or
in their entirety. However, if we identify significant risks or are unable to
meet our anticipated timeline, we will develop contingency plans as deemed
necessary at that time.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company's foreign sales are principally to Mexico. All foreign
transactions are denominated in U.S. dollars, therefore, the Company's exposure
to foreign currency fluctuations is minimal.

         The Company is exposed to changes in interest rates from its senior
subordinated notes, which are due in full in 2003. A hypothetical 100 basis
point adverse move (decrease) in interest rates along the entire interest rate
yield curve would adversely affect the net fair value of the Notes by
approximately $625,000 as of June 30, 1999.

                                OTHER INFORMATION

ITEM 1.   LEGAL PROCEEDINGS

         In November 1998, the Company executed a term sheet with the Palladin
Group, L.P. ("Palladin") concerning negotiations for a possible investment by
Palladin in certain new classes of securities of the Company which, at the time,
the Company was considering issuing to a certain fund managed by Palladin. The
Company subsequently terminated the negotiations in December 1998. An affiliate
of Palladin, Halifax Fund, L.P. ("Halifax"), filed a lawsuit on or about March
19, 1999 in San Diego Superior Court alleging that the termination violated
duties owed by the Company to Halifax under the term sheet. The lawsuit sought
compensatory damages of approximately $2.6 million and punitive damages of
approximately $12.0 million. In July 1999, the Company executed Settlement and
Release Agreements with Halifax Fund, L.P., Palladin Group, L.P., Granite
Financial Group, Inc., and Midori Capital Corporation. These agreements mutually
release and discharge all claims arising from this litigation. The settlement
required the Company to pay termination charges and attorney's fees of $198,000.

         From time to time, the Company is involved in legal proceedings, claims
and litigation arising in the ordinary course of business, the outcome of which,
in the opinion of management, would not have a material adverse effect on the
Company.

ITEM 4.  SUBMISSIONS OF MATTERS TO A VOTE OF SECURITY HOLDERS

         On June 4, 1999, the Company held an Annual Meeting of Shareholders at
which the following proposals were voted on by shareholders:

         1.   Election of two directors for a three-year term to expire at the

ITEM 5.  OTHER INFORMATION

RECENT DEVELOPMENTS

         On June 30, 1999, the Company's wholly owned subsidiaries Turf
Partners, Inc. and Agricultural Supply, Inc. entered into credit agreements with
Coast Business Credit (the "Coast Working Capital Facility") and San Diego-based
First National Bank (the "FNB Working Capital Facility"), respectively. The
Coast Working Capital Facility is a $25 million, three-year credit facility
based upon Turf Partners' eligible inventory and receivables and has an interest
rate of prime rate plus 1.00%. On July 2, 1999, Turf Partners drew down $15.1
million on the facility and the Company paid all amounts due under, and
terminated a line of credit with Imperial Bank. The Company had approximately
$10 million outstanding under a December 14, 1998 Credit Agreement with Imperial
Bank prior to the payoff. The FNB Working Capital Facility is a $10 million,
three-year credit facility based upon Agricultural Supply's eligible inventory
and receivables and has an interest rate of prime plus .25%. On July 2, 1999,
Agricultural Supply drew down $2.2 million on the facility.

         The foregoing summary of the terms of the Coast Working Capital
Facility and the FNB Working Capital Facility does not purport to be complete
and is qualified in its entirety by reference to the full text of the Coast
Working Capital Facility and the FNB Working Capital Facility and their
corresponding promissory notes, copies of which are attached hereto as Exhibits
10.3, 10.4 and 10.5 and incorporated herein by reference.

FACTORS THAT COULD AFFECT FUTURE PERFORMANCE

         This report contains certain forward looking statements about the
business and financial condition of the Company, including various statements
contained in "Management's Discussion and Analysis of Financial Condition and
Results of Operations." The actual results of the Company could differ
materially from any forward looking statements contained herein. The following
information sets forth certain factors that could cause the actual results to
differ materially from those contained in the forward looking statements. For a
more detailed discussion of the factors that could cause actual results to
differ, see "Item 1: Business -- Factors That Could Affect Future Performance"
in the Company's Form 10-K for the fiscal year ended December 31, 1998.

         At June 30, 1999, the Company had an accumulated deficit of $27.7
million. The Company has been principally engaged in organizational activities,
research and development, licensing activities, product introductions and the
establishment of a sales and marketing organization. The Company's recent losses
have resulted in part from expenditures for product development, U.S. patent
protection and sales and marketing expenses, including the costs of the
Company's recent dealer acquisitions.

         In order to expand its business and achieve significant growth in
sales, the Company must continue to broaden its sales and marketing capability
and increase the size of its customer base, in part through the acquisition of
independent dealers and distributors. Although sales of certain of the Company's
products are growing, the Company's products and operations remain in the early
stages of market introduction and are subject to the risks inherent in the
commercialization of new product concepts. These risks include unforeseen
problems, delays, expenses and complications frequently encountered in the early
phases of research, development and commercialization of products, and expenses
associated with hiring and training additional sales, marketing and customer
service personnel.

         Distribution and sales of the Company's products have historically
occurred through direct sales efforts and independent dealers and distributors.
The Company has initiated a strategy of attempting to establish a nationwide
distribution system for its products through the acquisition of various
independent

                                       15

<PAGE>

dealers and distributors. Any failure to identify acquisition candidates
properly, any large expenditures on acquisitions that prove to be
unprofitable, or any inability to sell the Company's proprietary products
through the acquired distribution system could have a material adverse effect
on the Company's business, financial position and results of operations.

         The Company's success will be dependent in large measure upon its
ability to obtain and enforce patent protection for its products, maintain
confidentiality of its trade secrets and know-how and operate without
infringing upon the proprietary rights of third parties. Despite precautions
taken by the Company, it may be possible for a third party to copy or
otherwise obtain or use the Company's products or technology without
authorization, or to develop similar products or technology independently.

         The Company plans to acquire the rights to additional microbial
products. The Company manages limited research and development activity in
its own laboratory, and funds university research with respect to microbial
products. Although the Company is actively seeking to obtain licenses for
additional microbial products, there can be no assurance that the Company
will be successful in obtaining any such licenses on terms acceptable to the
Company, if at all.

         The Company may be exposed to liability resulting from the commercial
use of its products. Such liability might result from claims made directly by
customers or others manufacturing such products on behalf of the Company. The
Company currently carries a product liability insurance policy with an aggregate
limit of $15 million. There can be no assurance, however, that such product
liability insurance will adequately protect the Company against any product
liability claim. A product liability or other claim with respect to uninsured
liabilities or in excess of insured liabilities could have a material adverse
effect on the business and prospects of the Company.

         Some states have laws imposing liability on certain parties for the
release of fertilizers and other agents into the environment in certain manners
or concentrations. Such liability could include, among other things,
responsibility for cleaning up the damage resulting from such a release. In
addition, the federal Comprehensive Environmental Response, Compensation and
Liability Act (CERCLA), commonly known as the "Superfund" law, and other
applicable laws impose liability on certain parties for the release into the
environment of hazardous substances, which might include fertilizers and water
treatment chemicals. The Company is also subject to certain other environmental
laws, including the Environmental Protection Act, the Toxic Substance Control
Act, the Resource Conservation and Recovery Act, the Clean Air Act and the Clean
Water Act and may be subject to other present and potential future federal,
state or local regulations. The Company does not currently maintain insurance
for any environmental claims which might result from the release of its products
into the environment in a manner or in concentrations not permitted by law.
Thus, a claim for environmental liability could have a material adverse effect
on the Company.

         The Company competes for market share with a number of companies that
manufacture and market chemical compounds. In addition, a number of companies
are developing biological and organic products for turf maintenance. Many of
these competitors have substantially greater capital resources, research and
development staffs and facilities than the Company, and many of these
competitors have extensive experience in turf maintenance. The fields of
biotechnology and related technologies in which the Company is engaged have
undergone rapid and significant technological changes. The Company expects that
the technologies associated with its research and development will continue to
develop rapidly. There can be no assurance that the Company will be able to
establish itself in such fields or, if established, that it will be able to
maintain a competitive position. Further, there can be no assurance that the
development by others of new or improved processes or products will not make the
Company's products and processes less competitive or obsolete.

                                       16

<PAGE>

         The Company is dependent upon the active participation of William B.
Adams, its Chairman of the Board and Chief Executive Officer, and Douglas M.
Gloff, its President and Chief Operating Officer. The loss of the services of
either of these individuals could have a material adverse effect upon the
Company's future operations. The Company's success depends in large part on its
ability to attract and retain qualified scientific, financial and management
personnel. The Company faces competition for such persons from other companies,
academic institutions, government entities and other organizations. There can be
no assurance that the Company will be successful in recruiting or retaining
personnel of the requisite caliber or in adequate numbers to enable it to
conduct its business as proposed.

Ladies and Gentlemen:

                  Reference is made to the Note and Warrant Purchase Agreement,

                  1.2. ADDITION OF SECTION 9.8. The Note Agreement is hereby
amended by adding new section 9.8 immediately following section 9.7 thereof:

                           "9.8. CONTINGENT PREPAYMENT UPON SALE OF EQUITY. In
         the event that at any time there shall be Excess Equity Proceeds, then
         the Company shall give prompt written notice thereof to each holder of
         the Notes, by facsimile transmission or registered mail (and shall
         confirm such notice by prompt telephonic advice to an investment
         officer of each such holder), which notice shall contain a written,
         irrevocable offer by the Company to prepay, on a date specified in such
         notice (which date shall be not less than 30 days and not more than 60

                              W I T N E S S E T H :

                  WHEREAS, ECO SOIL SYSTEMS, INC., a Nebraska corporation
(the "Company"), entered into separate Note and Warrant Purchase Agreements,
dated as of August 25, 1998 (the "Original Note Agreements"), with the

                  WHEREAS, in connection with the amendments referred to

<PAGE>

Guarantors reaffirm the guaranties and agreements contained in the Original
Guaranty and amend and restate the Original Guaranty so as expressly to
guarantee the amounts due and payable by the Company and the other
obligations and covenants of the Company under the Notes and the Note
Agreements as amended as described above; and

                  WHEREAS, capitalized terms not otherwise defined herein
shall have the meanings specified therefor in the Note Agreements.

                  NOW, THEREFORE, in consideration of the premises and the
covenants herein contained, the parties hereto agree as follows:

                  1. GUARANTY. 1.1. GUARANTY OF EACH OF THE GUARANTORS. The
Guarantors, jointly and severally, unconditionally and irrevocably guarantee to
each holder from time to time of any of the Notes:

                  (a) the due, prompt and complete payment by the Company of
         the principal of and interest on, and any other amount due under, the
         Notes, when and as the same shall become due and payable (whether at
         stated maturity or by prepayment or by declaration or otherwise) in
         accordance with the terms of the Notes and of the Note Agreements, and

                  (b) the due, prompt and faithful performance of, and
         compliance with, all obligations, covenants, terms, conditions and
         undertakings of the Company contained in the Notes and the Note
         Agreements and in any other agreement or document executed by the
         Company pursuant to the Note Agreements (the Note Agreements, the
         Notes and such other agreements and documents being sometimes
         collectively hereinafter referred to as the "Guaranteed Documents",
         and the amounts payable by the Company under any of the Guaranteed
         Documents and all other obligations of the Company thereunder being
         sometimes collectively hereinafter referred to as the "Guaranteed
         Obligations").

                  This guaranty is a guaranty of payment, performance and
compliance and not of collectibility and is in no way conditioned or
contingent upon any attempt to collect from or enforce performance or
compliance by the Company or upon any other event, contingency, circumstance
or condition whatsoever. If for any reason whatsoever the Company shall


                                      -2-
<PAGE>

fail or be unable duly, punctually and fully to pay such amounts as and when
the same shall become due and payable or to perform or comply with any other
Guaranteed Obligation, whether or not such failure or inability shall
constitute an "Event of Default" under any Guaranteed Document, the
Guarantors, without demand, presentment, protest or notice of any kind, will
forthwith pay or cause to be paid such amounts to the holders of the Notes
entitled thereto under the terms of such Guaranteed Document, in lawful money
of the United States, at the place specified in the Note Agreements, or
perform or comply with such Guaranteed Obligations or cause such Guaranteed
Obligations to be performed or complied with, together with interest on any
amount due and owing from the Company at the rate applicable under the
Guaranteed Documents from the date the same becomes due and payable to the
date of payment. The Guarantors, promptly after demand, will reimburse to
each holder of the Notes all costs and expenses of collecting such amounts or
otherwise enforcing the Note Agreements, including, without limitation, the
reasonable fees and expenses of counsel.

                  1.2. GUARANTORS' OBLIGATIONS UNCONDITIONAL. The obligations
of the Guarantors under this Agreement are primary, absolute and
unconditional obligations of the Guarantors, are not subject to any
counterclaim, set-off, deduction, diminution, abatement, recoupment,
suspension, deferment, reduction or defense based upon any claim the
Guarantors or any other Person may have against the Company or any other
Person, and shall remain in full force and effect without regard to, and
shall not be released, discharged or in any way affected by, any circumstance
or condition whatsoever (whether or not any Guarantor or the Company shall
have any knowledge or notice thereof), including, without limitation, in each
case, to the extent permitted by law:

                  (a) any amendment of or change in, or waiver of, any of the
         Guaranteed Documents;

                  (b) any furnishing, acceptance or release of, or any defect
         in, any security for any of the Guaranteed Obligations;

                  (c) any failure, omission or delay on the part of the Company
         to conform or comply with any term of any of the Guaranteed Documents
         or any other instrument or agreement referred to in section 1.1 above,
         including,


                                      -3-
<PAGE>

         without limitation, failure to give notice to any Guarantor of the
         occurrence of a default or an "Event of Default" under any Guaranteed
         Document;

                  (d) any waiver of the payment, performance or observance of
         any of the obligations, conditions, covenants or agreements contained
         in any Guaranteed Document, or any other waiver, consent, extension,
         indulgence, compromise, settlement, release or other action or
         inaction under or in respect of any of the Guaranteed Documents or any
         other instrument or agreement referred to in section 1.1 above or any
         obligation or liability of the Company, or any exercise or
         non-exercise of any right, remedy, power or privilege under or in
         respect of any such instrument or agreement or any such obligation or
         liability;

                  (e) any failure, omission or delay on the part of the holder
         of any of the Notes to enforce, assert or exercise any right, power or
         remedy conferred on it in the Note Agreements, or any such failure,
         omission or delay on the part of such holder in connection with any
         Guaranteed Document, or any other action on the part of such holder;

                  (f) any voluntary or involuntary bankruptcy, insolvency,
         reorganization, arrangement, readjustment, assignment for the benefit
         of creditors, composition, receivership, conservatorship,
         custodianship, liquidation, marshalling of assets and liabilities or
         similar proceedings with respect to the Company, any Guarantor or any
         other Person or any of their respective properties or creditors, or
         any action taken by any trustee or receiver or by any court in any
         such proceeding;

                  (g) any limitation on the liability or obligations of the
         Company or any other Person under any of the Guaranteed Documents, or
         any discharge, termination, cancellation, frustration, irregularity,
         invalidity or unenforceability, in whole or in part, of any of the
         Guaranteed Documents or any other agreement or instrument referred to
         in section 1.1 above or any term hereof;

                  (h) any merger or consolidation of the Company or any
         Guarantor into or with any other corporation, or


                                      -4-
<PAGE>

         any sale, lease or transfer of any of the assets of the Company or any
         Guarantor to any other Person;

                  (i) any change in the ownership of any shares of capital
         stock of the Company, or any change in the corporate relationship
         between the Company and any Guarantor, or any termination of such
         relationship;

                  (j) any release or discharge, by operation of law, of any
         Guarantor from the performance or observance of any of the Guaranteed
         Obligations; or

                  (k) any other occurrence, circumstance, happening or event
         whatsoever, whether similar or dissimilar to the foregoing, whether
         foreseen or unforeseen, and any other circumstance which might
         otherwise constitute a legal or equitable defense or discharge of the
         liabilities of a guarantor or surety or which might otherwise limit
         recourse against the Guarantors (other than a defense of payment or
         performance).

                  1.3. FULL RECOURSE OBLIGATIONS. Except as provided herein,
the obligations of the Guarantors set forth herein constitute the full
recourse obligations of each of the Guarantors enforceable against it to the
full extent of all its assets and properties.

                  1.4. WAIVER. The Guarantors unconditionally waive, to the
extent permitted by applicable law, (A) notice of any of the matters referred
to in section 1.2, (B) notice to the Guarantors of the incurrence of any of
the Guaranteed Obligations, notice to the Guarantors or the Company of any
breach or default by the Company with respect to any of the Guaranteed
Obligations or any other notice that may be required, by statute, rule of law
or otherwise, to preserve any rights of any holder of any of the Notes
against the Guarantors, (c) presentment to or demand of payment from the
Company or the Guarantors with respect to any Note or protest for nonpayment
or dishonor, (D) any right to the enforcement, assertion, exercise or
exhaustion by any holder of any of the Notes of any right, power, privilege
or remedy conferred in the Note Agreements or any other Guaranteed Document
or otherwise, (E) any requirement of diligence on the part of any holder of
any of the Notes, (F) any requirement to mitigate the damages resulting from
any default under any Guaranteed Document, (G) any notice of any sale,
transfer or other disposition of any right or title to or interest in any
Note by any holder thereof or in any


                                      -5-
<PAGE>

other Guaranteed Document, (H) any release of the Guarantors from its
obligations hereunder resulting from any loss by it of its rights of
subrogation hereunder and (I) any other circumstance whatsoever which might
otherwise constitute a legal or equitable discharge, release or defense of a
guarantor or surety or which might otherwise limit recourse against the
Guarantors.

                  1.5. SUBROGATION. Upon the payment in full of all principal
of and interest on the Notes and any other amounts payable by the Company
under the Guaranteed Documents, the Guarantors shall be subrogated to the
rights of the holders of the Notes in respect of any payment or other
obligation with respect to which an amount has been payable by the Guarantors
hereunder. The Guarantors shall not seek to exercise any rights of
subrogation, reimbursement or indemnity arising from payments made by the
Guarantors pursuant to the provisions of this Agreement until the full and
complete payment or performance and discharge of the Guaranteed Obligations.

                  1.6. EFFECT OF BANKRUPTCY PROCEEDINGS, ETC. (a) This
Guaranty shall continue to be effective or be automatically reinstated, as
the case may be, if at any time any payment made by any Person on account of
any of the sums due any holder of any of the Notes pursuant to the terms of
the Notes, the Note Agreements or any other Guaranteed Document is rescinded
or must otherwise be restored or returned by such holder upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Company or any
other Person, or upon or as a result of the appointment of a custodian,
receiver, trustee or other officer with similar powers with respect to the
Company or other Person or any substantial part of its property, or
otherwise, all as though such payment had not been made.

                  (b) If an event permitting the acceleration of the maturity
of the principal amount of the Notes shall at any time have occurred and be
continuing, and such acceleration shall at such time be prevented by reason
of the pendency against the Company or any other Person of any case or
proceeding contemplated by section 1.6(a) then, for the purpose of defining
the obligation of the Guarantors under this Guaranty, the maturity of the
principal amount of the Notes shall be deemed to have been accelerated with
the same effect as if an acceleration had occurred in accordance with the
terms of the Note Agreement, and the Guarantors shall forthwith pay such
principal amount, all accrued and unpaid


                                      -6-
<PAGE>

interest thereon and any other amounts guaranteed hereunder without further
notice or demand.

                  1.7. ENDORSEMENT ON NOTES. The Guarantors will execute the
guaranty appended to each Note upon the issuance of such Note. If any Note
shall be issued in exchange for or in replacement of any other Note pursuant
to the Note Agreements, the Guarantors will execute on the Note so issued its
guaranty substantially identical to that set forth on the Note so exchanged.
The absence of any such guaranty on any Note shall not, however, affect the
obligations of the Guarantors hereunder.

                  1.8. TERM OF GUARANTY. This Guaranty and all guarantees,
covenants and agreements of the Guarantors contained herein shall continue in
full force and effect and shall not be discharged until such time as all of
the amounts due under the Notes shall be paid in full.

                  2. MAXIMUM LIABILITY. The liability of each of the
Guarantors under this Agreement shall not exceed the greater of (A) the net
benefit realized by such Guarantor or any Subsidiary of such Guarantor from
the proceeds of the issuance of the Notes and (B) the greater of (I) 95% of
the Adjusted Net Assets of such Guarantor on the date of this Agreement and
(II) 95% of the Adjusted Net Assets of such Guarantor on the date of any
payment hereunder. For purposes of this Agreement, the term "Adjusted Net
Assets" means, with respect to each of the Guarantors at any date of
determination, the lesser of (X) the amount by which the fair value of the
property and assets of such Guarantor exceeds the total amount of liabilities
(including, without limitation, contingent liabilities but excluding
liabilities under the Guaranteed Documents) of such Guarantor at such date
and (Y) the amount by which the present fair salable value of the property
and assets of such Guarantor at such date exceeds the amount that will be
required to pay the probable liability of such Guarantor on its debts
(excluding the Guaranteed Obligations), as they become absolute and matured.

                  3. SUBORDINATION. The obligations of the Guarantor
hereunder with respect to the Note Agreements and the Notes (the
"Subordinated Debt") shall be subordinate and junior in right of payment to
all Superior Debt (as defined in section 13.2 of the Note Agreements) to the
extent and in the manner provided in section 13 of each of the Note
Agreements. For purposes of this section 3, all references


                                      -7-
<PAGE>

to the Company in section 13 of the Note Agreement shall be read to include
references to the Company and any Guarantor.

                  4. REPRESENTATIONS AND WARRANTIES. The Guarantors hereby
jointly and severally represent and warrant as follows:

                  (a) ORGANIZATION, STANDING, ETC. Each Guarantor is a
         corporation duly organized, validly existing and in good standing
         under the laws of the jurisdiction of its incorporation, and each has
         all requisite corporate power and authority to own and operate its
         properties, to carry on its business as now conducted and as proposed
         to be conducted and to enter into and to carry out the terms of this
         Agreement. This Agreement has been duly authorized by all necessary
         corporate action on the part of each Guarantor and has been duly
         executed and delivered by each Guarantor.

                  (b) QUALIFICATION. Each Guarantor is duly qualified and in
         good standing as a foreign corporation duly authorized to do business
         in each jurisdiction (other than the jurisdiction of its
         incorporation) in which the nature of its activities or the character
         of the properties it owns or leases makes such qualification necessary

otherwise), Borrower shall, whenever requested by Coast, use its best efforts
to cause such third party to execute and deliver to Coast, in form acceptable
to Coast, such waivers and subordinations as Coast shall specify, so as to

superior to the rights of any such third party. In the event that such

third parties, Coast will have a continuing right to institute a reserve for
payment of rent and other sums owing to any such third parties or Coast may
make any Collateral located on the premises of any such third party
ineligible for lending purposes. Borrower will keep in full force and effect,
and will comply with all the terms of, any lease of real property where any
of the Collateral now or in the future may be located.

         6.5 MAINTENANCE OF COLLATERAL. Borrower will maintain the Collateral

in their original form, duly endorsed to Coast, to be applied to the
Obligations in such order as Coast shall determine. Coast may, in its
discretion, require that all proceeds of Collateral be deposited by Borrower
into a lockbox account, or such other "blocked account" as Coast may specify,
pursuant to a blocked account agreement in such form as Coast may specify.
Coast or its designee may, at any time, notify Account Debtors that Coast has
been granted a security interest in the Receivables.

         7.5 REMITTANCE OF PROCEEDS. All proceeds arising from the
disposition of any Collateral shall be delivered to Coast within one (1)
Business Day after receipt by Borrower, in their original form, duly endorsed
to Coast, to be applied to the Obligations in such order as Coast shall
determine. Borrower agrees that it will not commingle proceeds of Collateral
with any of Borrower's other funds or property, but will hold such proceeds
separate and apart from such other funds and property and in an express trust
for Coast. Nothing in this Section limits the restrictions on disposition of
Collateral set forth elsewhere in this Agreement.

         7.6 DISPUTES. Borrower shall notify Coast promptly of all material
disputes or claims relating to Receivables. Borrower shall not forgive
(completely or partially), compromise or settle any Receivable for less than
payment in full, or agree to do any of the foregoing, except that Borrower
may do so, provided that: (a) Borrower does so in good faith, in a
commercially reasonable manner, in the ordinary course of business, and in
arm's length transactions, which are reported to Coast on the regular reports
provided to Coast; (b) no Default or Event of Default has occurred and is
continuing; and (c) taking into account all such discounts settlements and
forgiveness, the total outstanding Loans will not exceed the Credit Limit.
Coast may, at any time after the occurrence and during the continuance of an
Event of Default, settle or adjust disputes or claims directly with Account
Debtors for amounts and upon terms which Coast considers advisable in its
reasonable credit judgment and, in all cases, Coast shall credit Borrower's
Loan account with only the net amounts received by Coast in payment of any
Receivables.

         7.7 RETURNS. Provided no Event of Default has occurred and is
continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason
for such return and promptly issue a credit memorandum to the Account Debtor
in the appropriate amount. In the event any attempted return occurs after the

                                     12
<PAGE>

       Coast Business Credit                   Loan and Security Agreement
_______________________________________________________________________________

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

         7.8 VERIFICATION. Coast may, from time to time, verify directly with
the respective Account Debtors the validity, amount and other matters
relating to the Receivables, by means of mail, telephone or otherwise, either
in the name of Borrower or Coast or such other name as Coast may choose.

         7.9 NO LIABILITY. Coast shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss
or destruction of, any goods, the sale or other disposition of which gives
rise to a Receivable, or for any error, act, omission or delay of any kind
occurring in the settlement, failure to settle, collection or failure to
collect any Receivable, or for settling any Receivable in good faith for less
than the full amount thereof, nor shall Coast be deemed to be responsible for
any of Borrower's obligations under any contract or agreement giving rise to
a Receivable. Nothing herein shall, however, relieve Coast from liability for
its own gross negligence or willful misconduct.

8.       ADDITIONAL DUTIES OF THE BORROWER

         8.1 FINANCIAL AND OTHER COVENANTS. Borrower shall at all times
comply with the financial and other covenants set forth in the Schedule.

         8.2 INSURANCE. Borrower shall, at all times insure all of the
tangible personal property Collateral and carry such other business insurance
(including, without limitation, coverage in excess of the highest
consolidated inventory balance reflected in Borrower's financial statements
or reporting provided to Coast, with said coverage amount to be determined by
Coast in its sole discretion), with insurers reasonably acceptable to Coast,
in such form and amounts as Coast may reasonably require, and Borrower shall
provide evidence of such insurance to Coast, so that Coast is satisfied that
such insurance is, at all times, in full force and effect. All liability
insurance policies of Borrower shall name Coast as an additional insured, and
shall provide coverage for environmental related claims and issues, with said
coverage to be acceptable to Coast in its sole and absolute discretion, and
all property casualty and related insurance policies of Borrower shall name
Coast as a loss payee thereon and Borrower shall cause a lender's loss payee
endorsement in form reasonably acceptable to Coast. Upon receipt of the
proceeds of any such insurance, Coast shall apply such proceeds in reduction
of the Obligations as Coast shall determine in its sole discretion, except
that, provided no Default or Event of Default has occurred and is continuing,
Coast shall release to Borrower insurance proceeds with respect to Equipment
totaling less than the amount set forth in Section 8 of the Schedule, which
shall be utilized by Borrower for the replacement of the Equipment with
respect to which the insurance proceeds were paid. Coast may require
reasonable assurance that the insurance proceeds so released will be so used.
If Borrower fails to provide or pay for any insurance, Coast may, but is not
obligated to, obtain the same at Borrower's expense. Borrower shall promptly
deliver to Coast copies of all reports made to insurance companies.

         8.3 REPORTS. Borrower, at its expense, shall provide Coast with the
written reports set forth in Section 8 of the Schedule, and such other
written reports with respect to Borrower (including budgets, sales
projections, operating plans and other financial documentation), as Coast
shall from time to time reasonably specify.

         8.4 ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times but
not less frequently than quarterly and on one (1) Business Day's notice,
Coast, or its agents, shall have the right to perform Audits. Coast shall
take reasonable steps to keep confidential all confidential information
obtained in any Audit, but Coast shall have the right to disclose any such
information to its auditors, regulatory agencies, and attorneys, and pursuant
to any subpoena or other legal process. The Audits shall be at Borrower's
expense and the charge for the Audits shall be Seven Hundred Fifty Dollars
($750) per person per day (or such higher amount as shall represent Coast's
then current standard charge for the same), plus reasonable out-of-pocket
expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at
any location other than Borrower's Address, without first notifying Coast of
the same and obtaining the written agreement from such

                                     13
<PAGE>

       Coast Business Credit                   Loan and Security Agreement
_______________________________________________________________________________

accounting firm, service bureau or other third party to give Coast the same
rights with respect to access to books and records and related rights as
Coast has under this Loan Agreement. Borrower shall also take all necessary
steps to assure that its material accounting and software, systems and
applications, and those of its accounting firm, service bureau or any other
third party vendor or supplier, will, on a timely basis, adequately and
completely address the Year 2000 Problem in all material respects.

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

            (a) merge or consolidate with another entity, except in a
transaction in which (i) the owners of the Borrower hold at least fifty
percent (50%) of the ownership interest in the surviving entity immediately
after such merger or consolidation, and (ii) the Borrower is the surviving
entity;

            (b) acquire any assets, except (i) in the ordinary course of
business, or (ii) in a transaction or a series of transactions not involving
the payment of an aggregate amount in excess of the amount set forth in
Section 8 of the Schedule;

            (c) enter into any other transaction not permitted hereunder
outside the ordinary course of business provided, however, that Borrower's
use and exploitation of the BoiJects and related equipment/technology as
permitted pursuant to the BioJect leases will be deemed to be in the ordinary
course of Borrower's business;

            (d) sell or transfer any Collateral, except for: (i) the sale of
finished Inventory in the ordinary course of Borrower's business, (ii) the
sale of obsolete or unneeded Equipment in the ordinary course of business,
and (iii) other sales or transfers the aggregate market value of such
Collateral sold or otherwise disposed of in any year not to exceed Five
Hundred Thousand Dollars ($500,000) and the consideration received for such
Collateral being at least equal to the fair market value of such Collateral
provided: (i) such sales could not reasonably be expected to have a Material
Adverse Effect, and (ii) no Event of Default has occurred and is continuing
or will result from such sales or transfers;

            (e) sell Inventory on a sale-or-return, guaranteed sale,
consignment, or other contingent basis wherein the proceeds of all of said
sales exceed ten percent (10%) of Borrower's total sales of any kind during
any monthly period;

            (f) make any loans of any money or other assets, except (i)
advances to customers or suppliers in the ordinary course of business, (ii)
travel advances, employee relocation loans and other employee loans and
advances in the ordinary course of business, and (iii) loans to employees,
officers and directors for the purpose of purchasing equity securities of the
Borrower;

            (g) incur any debts not permitted hereunder, outside the ordinary
course of business, which would have a Material Adverse Effect;

            (h) guarantee or otherwise become liable with respect to the
obligations of another party or entity other than guarantees pursuant to the
Term Loan and guarantees with respect to the Note Purchase Agreement;

            (i) pay or declare any dividends or distributions on the
ownership interests in Borrower (except for: (i) dividends or distributions
payable solely in stock form of ownership interests in Borrower), and (ii)
upstreaming of funds to Guarantor in an amount not to exceed 75% of net
income per month; PROVIDED, HOWEVER, that the total of said upstreaming
cannot exceed (y) 75% of period-to-date net income, and (z) 75% of fiscal
year end net income. Said calculation of period-to-date net income will
commence with the month of July, 1999. Notwithstanding the foregoing, any
amounts paid by Borrower to Guarantor as part of the initial funding of Loans
hereunder will not be subject to the limitations of this paragraph including
the upstreaming limitations of this paragraph;

            (j) sidestream funds or distributions of any kind to other
subsidiaries of Guarantor;

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

            (l) dissolve or elect to dissolve.

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

         8.6 LITIGATION COOPERATION. Should any third-party suit or
proceeding be instituted by or

                                     14
<PAGE>

       Coast Business Credit                   Loan and Security Agreement
_______________________________________________________________________________

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

         8.7 FURTHER ASSURANCES. Borrower agrees, at its expense, on request
by Coast, to execute all documents and take all actions, as Coast, may deem
reasonably necessary or useful in order to perfect and maintain Coast's
perfected security interest in the Collateral, and in order to fully
consummate the transactions contemplated by this Agreement.

9.       TERM

         9.1 MATURITY DATE. This Agreement shall continue in effect until the
Maturity Date; provided that the Maturity Date shall automatically be
extended, and this Agreement shall automatically and continuously renew, for
successive additional terms of one year each, unless one party gives written
notice to the other, not less than one hundred twenty (120) days prior to the
Maturity Date or the next Renewal Date, that such party elects to terminate
this Agreement effective on the Maturity Date or such next Renewal Date. If
this Agreement is renewed under this Section 9.1, Borrower shall pay to Coast
a Renewal Fee in the amount shown in Section 3 of the Schedule. The Renewal
Fee shall be due and payable on the Renewal Date and thereafter shall bear
interest at a rate equal to the rate applicable to the Receivable Loans.

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

         9.3 PAYMENT OF OBLIGATIONS. On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether
or not all or any part of such Obligations are otherwise then due and
payable. Without limiting the generality of the foregoing, if on the Maturity
Date, the Renewal Date, or on any earlier effective date of termination,
there are any outstanding Letters of Credit issued by Coast or issued by
another institution based upon an application, guarantee, indemnity or
similar agreement on the part of Coast, then on such date Borrower shall
provide to Coast cash collateral in an amount equal to the face amount of all
such Letters of Credit plus all interest, fees and costs due or to become due
in connection therewith, to secure all of the Obligations relating to said
Letters of Credit, pursuant to Coast's then standard form cash pledge
agreement. Notwithstanding any termination of this Agreement, all of Coast's
security interests in all of the Collateral and all of the terms and
provisions of this Agreement shall continue in full force and effect until
all Obligations have been paid and performed in full; provided that, without
limiting the fact that Loans are subject to the good faith discretion of
Coast, Coast may, in its sole discretion, refuse to make any further Loans
after termination. No termination shall in any way affect or impair any right
or remedy of Coast, nor shall any such termination relieve Borrower of any
Obligation to Coast, until all of the Obligations have been paid and
performed in full. Upon payment and performance in full of all the
Obligations and termination of this Agreement, Coast shall promptly deliver
to Borrower termination statements, requests for reconveyances and such other
documents as may be required to fully terminate Coast's security interests.

10.      EVENTS OF DEFAULT AND REMEDIES

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

            (a) Any warranty, representation, statement, report or
certificate made or delivered to Coast by Borrower or any of Borrower's
officers, employees or agents, now or in the future, shall be untrue or
misleading and results in a Material Adverse Effect; or

thereon or any other monetary Obligation; or

            (c) the total Loans and other Obligations with respect to Loans
including, but not limited to, principal, interest, fees, costs, and expenses
relating thereto, outstanding at any time shall exceed the Credit Limit
provided, however, that if the excess is solely caused by Coast=s reduction
of advance rates against Eligible Receivables or Eligible Inventory and there
is no other Event of Default that has occurred and continuing, Borrower will
have five days to repay said excess before said excess will automatically
become an Event of Default; or

            (d) Borrower shall fail to deliver the proceeds of Collateral to
Coast as provided in Section 7.5 above, or shall fail to give Coast access to

Obligation, which failure is not cured within thirty (30) days after the date
due; or

encumbrance (other than a Permitted Lien) is made on all or any part of the
Collateral which is not cured within fifteen (15) days after the occurrence
of the same; or

            (h) any default or event of default occurs under any obligation
secured by a Permitted Lien, which is not cured within any applicable cure
period or waived in writing by the holder of the Permitted Lien and such
failure could reasonably be expected to have a Material Adverse Effect; or

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

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

under any reorganization, bankruptcy, insolvency, arrangement, readjustment

proceedings against Borrower or any Guarantor, is (i) not timely
controverted, or (ii) not cured by the dismissal thereof within forty-five
(45) days after the date commenced; or

bankruptcy or insolvency law which, with respect only to the commencement of
proceedings against such third party, is (i) not timely controverted, or (ii)
not cured by the dismissal thereof within forty-five (45) days after the date
commenced; or

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

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

business judgment; or

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

            (q) there shall be any Material Adverse Effect.

            (r) If an Event of Default, as defined in the Term Loan and
Security Agreement, has occurred.

Coast may cease making any Loans or extending any credit hereunder during any

         10.2 REMEDIES. Upon the occurrence, and during the continuance, of
any Event of Default, Coast, at its option, and without notice or demand of
any kind (all of which are hereby expressly waived by Borrower), may do any
one or more of the following:

            (a) Cease making Loans or otherwise extending credit to Borrower
under this Agreement or any other document or agreement;

            (b) Accelerate and declare all or any part of the Obligations to

may be found, and for that purpose Borrower hereby authorizes Coast without
judicial process to enter onto any of Borrower's premises without
interference to search for, take possession of, keep, store or remove any of
the Collateral, and remain on the premises or cause a custodian to remain on
the premises in exclusive control thereof, without charge for so long as
Coast deems it reasonably necessary in order to complete the enforcement of
its rights under this Agreement or any other agreement; PROVIDED, HOWEVER,
that should Coast seek to take possession of any of the Collateral by Court
process, Borrower hereby irrevocably waives:

                  (i)      any bond and any surety or security relating
thereto required by any statute, court rule or otherwise as an incident to
such possession;

                  (ii)     any demand for possession prior to the
commencement of any suit or action to recover possession thereof;

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

         (d) Require Borrower to assemble any or all of the Collateral and
make it available to Coast at places designated by Coast which are reasonably
convenient to Coast and Borrower, and to remove the Collateral to such
locations as Coast may deem advisable;

         (e) Complete the processing, manufacturing or repair of any
Collateral prior to a disposition thereof and, for such purpose and for the
purpose of removal, Coast shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge. Coast is hereby granted a license or other right to use, without
charge, Borrower's labels, patents, copyrights, rights of use of any name,
trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling
any Collateral and Borrower's rights under all licenses and all franchise
agreements shall inure to Coast's benefit;

         (f) Sell, lease or otherwise dispose of any of the Collateral, in
its condition at the time Coast obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private
sales, in lots or in bulk, for cash, exchange or other property, or on
credit, and to adjourn any such sale from time to time without notice other
than oral announcement at the time scheduled for sale. Coast shall have the
right to conduct such disposition on Borrower's premises without charge, for
such time or times as Coast deems reasonable, or on Coast's premises, or
elsewhere and the Collateral need not be located at the place of disposition.
Coast may directly or through any affiliated company purchase or lease any
Collateral at any such public disposition, and if permissible under
applicable law, at any private disposition. Any sale or other disposition of
Collateral shall not relieve

                                     17

_______________________________________________________________________________

Borrower of any liability Borrower may have if any Collateral is defective as
to title or physical condition or otherwise at the time of sale;

         (g) Demand payment of, and collect any Receivables and General
Intangibles comprising Collateral and, in connection therewith, Borrower
irrevocably authorizes Coast to endorse or sign Borrower's name on all
collections, receipts, instruments and other documents, to take possession of
and open mail addressed to Borrower and remove therefrom payments made with
respect to any item of the Collateral or proceeds thereof, and, in Coast's
sole discretion, to grant extensions of time to pay, compromise claims and
settle Receivables and the like for less than face value; and

         (h) Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the
preparation thereof or referring thereto.

      All attorneys' fees, expenses, costs, liabilities and obligations
incurred by Coast (including attorneys' fees and expenses incurred in
connection with bankruptcy) with respect to the foregoing shall be due from
the Borrower to Coast on demand. Coast may charge the same to Borrower's loan
account, and the same shall thereafter bear interest at the same rate as is
applicable to the Receivable Loans. Without limiting any of Coast's rights
and remedies, from and during the occurrence of any Event of Default, the
interest rate applicable to the Obligations shall be increased by an
additional three percent per annum.

         10.3 STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower
and Coast agree that a sale or other disposition (collectively, "sale") of
any Collateral which complies with the following standards will conclusively
be deemed to be commercially reasonable:

            (a) Notice of the sale is given to Borrower at least seven (7)
days prior to the sale, and, in the case of a public sale, notice of the sale
is published at least seven (7) days before the sale in a newspaper of
general circulation in the county where the sale is to be conducted;

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

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

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

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

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

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

         10.4 POWER OF ATTORNEY. Borrower grants to Coast an irrevocable
power of attorney coupled with an interest, authorizing and permitting Coast
(acting through any of its employees, attorneys or agents) at any time, at
its option, but without obligation, with or without notice to Borrower, and
at Borrower's expense, to do any or all of the following, in Borrower's name
or otherwise, but Coast agrees to exercise the following powers in a
commercially reasonable manner:

            (a) Execute on behalf of Borrower any documents that Coast may,
in its sole discretion, deem advisable in order to perfect and maintain
Coast's security interest in the Collateral, or in order to exercise a right
of Borrower or Coast, or in order to fully consummate all the transactions
contemplated under this Agreement, and all other present and future
agreements;

            (b) After and during the continuance of an Event of Default,
execute on behalf of Borrower any document exercising, transferring or
assigning any option to purchase, sell or otherwise dispose of or to lease
(as lessor or lessee) any real or personal property which is part of Coast's

mechanic's, materialmen's or other lien, or assignment or satisfaction of
mechanic's, materialmen's or other lien;

            (d) Take control in any manner of any cash or non-cash items of
payment or proceeds of Collateral; endorse the name of Borrower upon any
instruments, or documents, evidence of payment or Collateral that may come
into Coast's possession;

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

            (f) After and during the continuance of an Event of Default, pay,
contest or settle any lien, charge, encumbrance, security interest and
adverse claim in or to any of the Collateral, or any judgment based thereon,
or otherwise take any action to terminate or discharge the same;

            (g) After and during the continuance of an Event of Default,
grant extensions of time to pay, compromise claims and settle Receivables and
General Intangibles for less than face value and execute all releases and
other documents in connection therewith;

            (h) After and during the continuance of an Event of Default, pay
any sums required on account of Borrower's taxes or to secure the release of
any liens therefor, or both;

            (i) After and during the continuance of an Event of Default,
settle and adjust, and give releases of, any insurance claim that relates to
any of the Collateral and obtain payment therefor;

            (j) Instruct any third party having custody or control of any
books or records belonging to, or relating to, Borrower to give Coast the
same rights of access and other rights with respect thereto as Coast has
under this Agreement; and

            (k) After and during the continuance of an Event of Default, take
any action or pay any sum required of Borrower pursuant to this Agreement and
any other present or future agreements.

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

         10.5 APPLICATION OF PROCEEDS. All proceeds realized as the result of
any sale of the Collateral shall be applied by Coast first to the costs,
expenses, liabilities, obligations and attorneys' fees incurred by Coast in
the exercise of its rights under this Agreement, second to the interest due
upon any of the Obligations, and third to the principal of the Obligations,
in such order as Coast shall determine in its sole discretion. Any surplus
shall be paid to Borrower or other persons legally entitled thereto; Borrower
shall remain liable to Coast for any deficiency. If, Coast, in its sole
discretion, directly or indirectly enters into a deferred payment or other
credit transaction with any purchaser at any sale of Collateral, Coast

                                     19
<PAGE>

       Coast Business Credit                   Loan and Security Agreement
_______________________________________________________________________________

shall have the option, exercisable at any time, in its sole discretion, of
either reducing the Obligations by the principal amount of purchase price or
deferring the reduction of the Obligations until the actual receipt by Coast
of the cash therefor.

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

11.      GENERAL PROVISIONS

         11.1 INTEREST COMPUTATION. In computing interest on the Obligations,
all checks, wire transfers and other items of payment received by Coast
(including proceeds of Receivables and payment of the Obligations in full)
shall be deemed applied by Coast on account of the Obligations two (2)
Business Days after receipt by Coast of immediately available funds, and, for
purposes of the foregoing, any such funds received in the bank account
designated by Coast during Coast's normal business hours, shall be deemed
received on the day they are received PROVIDED, HOWEVER, if in the future
Coast's standard operating procedure should change, for a majority of Coast's
borrowers by number, with respect to deeming items of payment received on the
same day as they are received during normal business hours, Borrower agrees
to abide by such change. Coast shall be entitled to charge Borrower's account
for such two (2) Business Days of "clearance" or "float" at the rate(s) set
forth in Section 3 of the Schedule on all checks, wire transfers and other
items received by Coast, regardless of whether such two (2) Business Days of
"clearance" or "float" actually occur, and shall be deemed to be the
equivalent of charging two (2) Business Days of interest on such collections.
This across-the-board two (2) Business Day clearance or float charge on all
collections is acknowledged by the parties to constitute an integral aspect
of the pricing of Coast's financing of Borrower. Coast shall not, however, be
required to credit Borrower's account for the amount of any item of payment
which is unsatisfactory to Coast in its sole discretion, and Coast may charge
Borrower's loan account for the amount of any item of payment which is
returned to Coast unpaid.

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

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

         11.4 MONTHLY ACCOUNTINGS. Coast shall provide Borrower monthly with
an account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Coast), unless Borrower
notifies Coast in writing to the contrary within thirty (30) days after each
account is rendered, describing the nature of any alleged errors or omissions.

         11.5 NOTICES. All notices to be given under this Agreement shall be
in writing and shall be given either personally or by reputable private
delivery service or by regular first-class mail, facsimile or certified mail
return receipt requested, addressed to Coast or Borrower at the addresses
shown in the heading to this Agreement, or at any other address designated in
writing by one party to the other party. Notices to Coast shall be directed
to the Commercial Finance Division, to the attention of the Division Manager
or the Division Credit Manager. All notices shall be deemed to have been
given upon delivery in the case of notices personally delivered, faxed (at
time of confirmation of transmission), or at the expiration of one (1)
Business Day following delivery to the private delivery service, or two (2)
Business Days following the deposit thereof in the United States mail, with
postage prepaid.

_______________________________________________________________________________

         11.6 SEVERABILITY. Should any provision of this Agreement be held by
any court of competent jurisdiction to be void or unenforceable, such defect
shall not affect the remainder of this Agreement, which shall continue in
full force and effect.

         11.7 INTEGRATION. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Coast and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement. THERE
ARE NO ORAL UNDERSTANDINGS, REPRESENTATIONS OR AGREEMENTS BETWEEN THE PARTIES
WHICH ARE NOT SET FORTH IN THIS AGREEMENT OR IN OTHER WRITTEN AGREEMENTS
SIGNED BY THE PARTIES IN CONNECTION HEREWITH.

         11.8 WAIVERS. The failure of Coast at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or
any other present or future agreement between Borrower and Coast shall not
waive or diminish any right of Coast later to demand and receive strict
compliance therewith. Any waiver of any Default shall not waive or affect any
other Default, whether prior or subsequent, and whether or not similar. None
of the provisions of this Agreement or any other agreement now or in the
future executed by Borrower and delivered to Coast shall be deemed to have
been waived by any act or knowledge of Coast or its agents or employees, but
only by a specific written waiver signed by an authorized officer of Coast
and delivered to Borrower. Borrower waives demand, protest, notice of protest
and notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time
held by Coast on which Borrower is or may in any way be liable, and notice of
any action taken by Coast, unless expressly required by this Agreement.

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

         11.10 AMENDMENT. The terms and provisions of this Agreement may not
be waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Coast.

         11.11 TIME OF ESSENCE. Time is of the essence in the performance by
Borrower and Coast of each and every obligation under this Agreement.

         11.12 ATTORNEYS FEES, COSTS AND CHARGES. Borrower shall reimburse
Coast for all attorneys' fees (including attorneys' fees and expenses
incurred pursuant to bankruptcy) and all filing, recording, search, title
insurance, appraisal, audit, and other costs incurred by Coast, pursuant to,
or in connection with, or relating to this Agreement (whether or not a
lawsuit is filed), including, but not limited to, any attorneys' fees and
costs (including attorneys' fees and expenses incurred pursuant to
bankruptcy) Coast incurs in order to do the following: prepare and negotiate
this Agreement and the documents relating to this Agreement; obtain legal
advice in connection with this Agreement or Borrower; enforce, or seek to
enforce, any of its rights; prosecute actions against, or defend actions by,
Account Debtors; commence, intervene in, or defend any action or proceeding;
initiate any complaint to be relieved of the automatic stay in bankruptcy;
file or prosecute any probate claim, bankruptcy claim, third-party claim, or
other claim; examine, audit, copy, and inspect any of the Collateral or any
of Borrower's books and records; protect, obtain possession of, lease,
dispose of, or otherwise enforce Coast's security interest in, the
Collateral; and otherwise represent Coast in any litigation relating to
Borrower. If either Coast or Borrower files any lawsuit against the other
predicated on a breach of this Agreement, the prevailing party in such action
shall be entitled to recover its costs and attorneys' fees (including
attorneys' fees and expenses incurred pursuant to bankruptcy), including (but
not limited to) attorneys' fees and costs incurred in the enforcement of,
execution upon or defense of any order, decree, award or judgment. Borrower
shall also pay Coast's standard charges for returned checks and for wire
transfers, in effect from time to time. All attorneys' fees, costs and
charges (including attorneys' fees and expenses incurred pursuant to
bankruptcy) and other fees, costs and charges to which Coast may be entitled

                                     21
<PAGE>

       Coast Business Credit                   Loan and Security Agreement
_______________________________________________________________________________

pursuant to this Agreement may be charged by Coast to Borrower's loan account
and shall thereafter bear interest at the same rate as the Receivable Loans.

         11.13 BENEFIT OF AGREEMENT. The provisions of this Agreement shall
be binding upon and inure to the benefit of the respective successors,
assigns, heirs, beneficiaries and representatives of Borrower and Coast;
provided, however, that Borrower may not assign or transfer any of its rights
under this Agreement without the prior written consent of Coast, and any
prohibited assignment shall be void. No consent by Coast to any assignment
shall release Borrower from its liability for the Obligations. Coast may
assign its rights and delegate its duties hereunder without the consent of
Borrower. Coast reserves the right to syndicate all or a portion of the
transaction created herein or sell, assign, transfer, negotiate, or grant
participations in all or any part of, or any interest in Coast's rights and
benefits hereunder. In connection with any such syndication, assignment or
participation, Coast may disclose all documents and information which Coast
now or hereafter may have relating to Borrower or Borrower's business. To the
extent that Coast assigns its rights and obligations hereunder to a third
Person, Coast thereafter shall be released from such assigned obligations to
Borrower.

         11.14 PUBLICITY. Coast and Borrower are hereby authorized, at their
own expense, to issue appropriate press releases and to cause a tombstone to
be published announcing the consummation of this transaction and the
aggregate amount thereof.

         11.15 PARAGRAPH HEADINGS CONSTRUCTION. Paragraph headings are only
 used in this Agreement for convenience. Borrower and Coast acknowledge that
the headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe,
limit, define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between
the parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Coast or Borrower under any
rule of construction or otherwise.

         11.16 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all
acts and transactions hereunder and all rights and obligations of Coast and
Borrower shall be governed by the internal laws of the State of California,
without regard to its conflicts of law principles. As a material part of the
consideration to Coast to enter into this Agreement, Borrower (a) agrees that
all actions and proceedings relating directly or indirectly to this Agreement
shall, at Coast's option, be litigated in courts located within California,
and that the exclusive venue therefor shall be Los Angeles County; (b)
consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or
any other method permitted by law; and (c) waives any and all rights Borrower
may have to object to the jurisdiction of any such court, or to transfer or
change the venue of any such action or proceeding.

         11.17 MUTUAL WAIVER OF JURY TRIAL. BORROWER AND COAST EACH HEREBY
WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON,
ARISING OUT OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER
PRESENT OR FUTURE INSTRUMENT OR AGREEMENT BETWEEN COAST AND BORROWER, OR ANY
CONDUCT, ACTS OR OMISSIONS OF COAST OR BORROWER OR ANY OF THEIR DIRECTORS,
OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH
COAST OR BORROWER, IN ALL OF THE FOREGOING CASES, WHETHER SOUNDING IN
CONTRACT OR TORT OR OTHERWISE.

         11.18 CONFIDENTIALITY. Coast will maintain the confidentiality of
any non public information marked as confidential and relating to the
business operations and methodology of Borrower and financial performance of
Borrower ("Borrower Information") provided to Coast solely by the Borrower as
required under the terms of this Agreement, and will not disclose Borrower
Information to any person, other than employees, agents, attorneys or
accountants of Coast. Coast will not disclose Borrower Information to any
other party unless, prior to such disclosure, Coast obtains an executed
acknowledgment binding such party to maintain the confidentiality of the
information, prohibiting its disclosure except for the purposes permitted
under this Agreement, and agreeing that the information may not be used to
compete with the Borrower in any way. In the event Coast receives a subpoena
or other process for any Borrower Information, it will immediately

6.       REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

      In order to induce Coast to enter into this Agreement and to make the
Term Loan, Borrower represents and warrants to Coast as follows, and Borrower
covenants that the following representations will continue to be true, and
that Borrower will at all times comply with all of the following covenants:

      6.1   EXISTENCE AND AUTHORITY. Borrower is and will continue to be,
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization. Borrower is and will continue to be
qualified and licensed to do business in all jurisdictions in which any
failure to do so would have a Material Adverse Effect. The execution,
delivery and performance by Borrower of this Agreement, and all other
documents contemplated hereby (a) have been duly and validly authorized, (b)
are enforceable against Borrower in accordance with their terms (except as
enforcement may be limited by equitable principles and by bankruptcy,
insolvency, reorganization, moratorium or similar laws relating to creditors'
rights generally), and (c) do not violate Borrower's articles of
incorporation, or Borrower's by-laws, or any law or any material agreement or
instrument which is binding upon Borrower or its property, and (d) do not
constitute grounds for acceleration of any material indebtedness or
obligation under any material agreement or instrument which is binding upon
Borrower or its property.

      6.2   NAME; TRADE NAMES AND STYLES. The name of Borrower set forth in
the heading to this Agreement is its correct name. Listed on the Schedule are
all prior names of Borrower and all of Borrower's present and prior trade
names. Borrower shall give Coast thirty (30) days' prior written notice
before changing its name or doing business under any other name. Borrower has
complied, and will in the future comply, with all laws relating to the
conduct of business under a fictitious business name.

      6.3   PLACE OF BUSINESS; LOCATION OF COLLATERAL. The address set forth
in the heading to this Agreement is Borrower's chief executive office. In
addition, Borrower has places of business and Collateral is located only at
the locations set forth on the Schedule. Borrower will give Coast at least
thirty (30) days' prior written notice before opening any additional place of
business, changing its chief executive office, or moving any of the
Collateral except for the movement of BioJects in the ordinary course of
business to a location other than Borrower's Address or one of the locations
set forth on the Schedule.

      6.4   TITLE TO COLLATERAL; PERMITTED LIENS. Borrower is now, and will
at all times in the future be, the sole owner of all the Collateral, except
for items of Equipment, technology and intellectual property which are
leased/licensed by Borrower. The Collateral now is and will remain free and
clear of any and all liens, charges, security interests, encumbrances and
adverse claims, except for Permitted Liens. Coast now has, and will continue
to have, a first-priority perfected and enforceable security interest in all
of the Collateral, subject only to the Permitted Liens, and Borrower will at
all times defend Coast and the Collateral against all claims of others. None
of the Collateral now is or will be affixed to any real property in such a
manner, or with such intent, as to become a fixture. Borrower is not and will
not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises. Whenever any
Collateral is located upon premises in which any third party has an interest
(whether as owner, mortgagee, beneficiary under a deed of trust, lienholder,
landlord, warehouseman or


                                       7

<PAGE>

    Coast Business Credit              Term Loan and Security Agreement
_____________________________________________________________________________


otherwise), Borrower shall, whenever requested by Coast, use its best efforts
to cause such third party to execute and deliver to Coast, in form acceptable
to Coast, such waivers and subordinations as Coast shall specify, so as to
ensure that Coast's rights in the Collateral are, and will continue to be,
superior to the rights of any such third party. In the event that such
waivers and subordinations specified by Coast have not been obtained from
such third parties, Coast will have a continuing right to institute a reserve
for payment of rent and other sums owing to any such third parties. Borrower
will keep in full force and effect, and will comply with all the terms of,
any lease of real property where any of the Collateral now or in the future
may be located.

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

      6.6   BOOKS AND RECORDS. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with GAAP.

      6.7   FINANCIAL CONDITION, STATEMENTS AND REPORTS. All financial
statements now or in the future delivered to Coast have been, and will be,
prepared in conformity with GAAP (except, in the case of unaudited financial
statements, for the absence of footnotes and subject to normal year-end
adjustments) and now and in the future will fairly reflect the financial
condition of Borrower, at the times and for the periods therein stated.
Between the last date covered by any such statement provided to Coast and the
date hereof, there has been no Material Adverse Effect. Borrower is now and
will continue to be Solvent.

      6.8   TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments,
deposits and contributions now or in the future owed by Borrower. Borrower
may, however, defer payment of any contested taxes, provided that Borrower
(i) in good faith contests Borrower's obligation to pay the taxes by
appropriate proceedings promptly and diligently instituted and conducted,
(ii) notifies Coast in writing of the commencement of, and any material
development in, the proceedings, and (iii) posts bonds or takes any other
steps required to keep the contested taxes from becoming a lien upon any of
the Collateral. As of the date hereof, Borrower is unaware of any claims or
adjustments proposed for any of Borrower's prior tax years which could result
in additional taxes becoming due and payable by Borrower. Borrower has paid,
and shall continue to pay all amounts necessary to fund all present and
future pension, profit sharing and deferred compensation plans in accordance
with their terms, and Borrower has not and will not withdraw from
participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could
result in any liability of Borrower, including any liability to the Pension
Benefit Guaranty Corporation or its successors or any other governmental
agency. Borrower shall, at all times, utilize the services of an outside
payroll service providing for the automatic deposit of all payroll taxes
payable by Borrower.

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

      6.10  LITIGATION. Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in a
Material Adverse Effect. Borrower will promptly inform Coast in writing of
any claim, proceeding, litigation or investigation in the future threatened
or instituted by or against Borrower involving an amount set forth on the
Schedule.

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

      6.12  YEAR 2000 COMPLIANCE. As the result of a comprehensive review and
assessment undertaken by Borrower of Borrower's computer systems, software
and applications and after due inquiry made of


                                       8

Borrower's material suppliers, vendors and customers Borrower represents and

Effect.

      6.13  MERGER OF ACCOUNTING SYSTEMS. Borrower and Guarantor shall have
completed the merger of their accounting systems by September 1, 1999.

      6.14  ASSIGNMENT OF LICENSES. Within six (6) months of the Closing
Date, Borrower shall provide Coast with duly executed agreements from third
parties wherein such third parties agree to the assignment of Borrower's
license rights to Coast of certain intellectual property used in conjunction
with Borrower's equipment. Coast in its sole and absolute discretion will
determine which rights in intellectual property are to be assigned and the
form and substance of said assignments are to be acceptable to Coast in its
sole and absolute discretion.

      6.15  COPYRIGHTS. Within 60 days of the Closing Date and, if not
achievable within said time period, within a reasonable time period utilizing
Borrower's best efforts, Coast shall have received satisfactory evidence that
Borrower has registered its copyrights with the United States Copyright
Office and Coast shall have been provided with a duly executed security
agreement with respect to such copyrights, with said security agreement to be
in form and substance acceptable to Coast in its sole and absolute discretion.

7.    ADDITIONAL DUTIES OF THE BORROWER

      7.1   FINANCIAL AND OTHER COVENANTS. Borrower shall at all times comply
with the financial and other covenants set forth in the Schedule.

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

      7.3   REPORTS. Borrower, at its expense, shall provide Coast with the
written reports set forth in Section 8 of the Schedule, and such other
written reports with respect to Borrower (including budgets, sales
projections, operating plans and other financial documentation), as Coast
shall from time to time reasonably specify.

      7.4   ACCESS TO COLLATERAL, BOOKS AND RECORDS. At reasonable times but
not less frequently than quarterly and on one (1) Business Day's notice,
Coast, or its agents, shall have the right to perform Audits. Coast shall
take reasonable steps to keep confidential all confidential information
obtained in any Audit, but Coast shall have the right to disclose any such
information to its auditors, regulatory agencies, and attorneys, and pursuant
to any subpoena or other legal process. The Audits shall be at Borrower's
expense and the charge for the Audits shall be Seven Hundred Fifty Dollars
($750) per person per day (or such higher amount as shall represent Coast's
then current standard charge for the same), plus reasonable out-of-pocket
expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at
any location other than Borrower's Address, without first notifying Coast of
the same and obtaining the written agreement from such accounting firm,
service bureau or other third party to give Coast the same rights with
respect to access to books and records and related rights as Coast has under
this Loan Agreement. Borrower shall also take all necessary steps to assure
that its material accounting and software, systems and applications, and
those of its accounting firm, service bureau or any other third party vendor
or supplier, will, on a timely basis, adequately and completely address the
Year 2000 Problem in all material respects.

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

      7.7   FURTHER ASSURANCES. Borrower agrees, at its expense, on request
by Coast, to execute all documents and take all actions, as Coast, may deem
reasonably necessary or useful in order to perfect and maintain Coast's
perfected security interest in the Collateral, and in order to fully
consummate the transactions contemplated by this Agreement.

8.    TERM.

      8.1   MATURITY DATE. This Agreement shall continue in effect until the
Maturity Date.

      8.2   PREPAYMENT. Borrower may prepay the Term Loan in whole or in part
prior to the Maturity Date as follows effective three (3) Business Days after
written notice of intent to prepay is given to Coast by Borrower. Any
prepayment of the Term Loan in part but not in full will be applied to
installments on the Secured Term Promissory Note in inverse order of
maturity. At any time if the Revolving Loan is paid off and/or terminated for
any reason prior to its respective Maturity Date, the Term Loan shall become
immediately due and payable without notice, effective immediately. If the
Term Loan is prepaid by Borrower in full under this Section 8.2, at a time
when the Revolving Loan is paid off and the Loan and Security Agreement is
terminated for any reason, Borrower shall pay to Coast a Prepayment Fee in
the amount shown in Section 3 of the Schedule. The Prepayment Fee shall be
due and payable on the effective date of prepayment and thereafter shall bear
interest at a rate equal to the rate applicable to the Term Loan.
Notwithstanding the foregoing, there will be no prepayment fee if the Term
Loan and all other Obligations hereunder are prepaid in full prior to the
Maturity Date and the Revolving Loan is not prepaid and the Loan and Security
Agreement is not terminated prior to its maturity date as described in the
Loan and Security Agreement.

      8.3   PAYMENT OF OBLIGATIONS. The Term Loan shall be payable in
installments as provided in the Secured Term Promissory Note. Notwithstanding
any termination of this Agreement, all of Coast's security interests in all
of the Collateral and all of the terms and provisions of this Agreement shall
continue in full force and effect until all Obligations have been paid and
performed in full. No termination shall in any way affect or impair any right
or remedy of Coast, nor shall any such termination relieve Borrower of any
Obligation to Coast, until all of the Obligations have been paid and
performed in full. Upon payment and performance in full of all the
Obligations and termination of this Agreement, Coast shall promptly deliver
to Borrower termination statements, requests for reconveyances and such other
documents as may be required to fully terminate Coast's security interests.

9.    EVENTS OF DEFAULT AND REMEDIES.

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

agreement; or

            (n)   Except as permitted under Section 7.5(a), Borrower shall

on the premises or cause a custodian to remain on the premises in exclusive
control thereof, without charge for so long as Coast deems it reasonably
necessary in order to complete the enforcement of its rights under this
Agreement or any other agreement; PROVIDED, HOWEVER, that should Coast seek
to take possession of any of the Collateral by Court process, Borrower hereby
irrevocably waives:

                  (i)   any bond and any surety or security relating thereto
      required by any statute, court rule or otherwise as an incident to such
      possession;

                  (ii)  any demand for possession prior to the commencement of
      any suit or action to recover possession thereof; and

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

            (d)   Require Borrower to assemble any or all of the Collateral
and make it available to Coast at places designated by Coast which are
reasonably convenient to Coast and Borrower, and to remove the Collateral to
such locations as Coast may deem advisable;

            (e)   Complete the processing, manufacturing or repair of any
Collateral prior to a disposition thereof and, for such purpose and for the
purpose of removal, Coast shall have the right to use Borrower's premises,
vehicles, hoists, lifts, cranes, equipment and all other property without
charge. Coast is hereby granted a license or other right to use, without
charge, Borrower's labels, patents, copyrights, rights of use of any name,
trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling
any Collateral and Borrower's rights under all licenses and all franchise
agreements shall inure to Coast's benefit;

            (f)   Sell, lease or otherwise dispose of any of the Collateral,
in its condition at the time Coast obtains possession of it or after further
manufacturing, processing or repair, at one or more public and/or private
sales, in lots or in bulk, for cash, exchange or other property, or on
credit, and to adjourn any such sale from time to time without notice other
than oral announcement at the time scheduled for sale. Coast shall have the
right to conduct such disposition on Borrower's premises without charge, for
such time or times as Coast deems reasonable, or on Coast's premises, or
elsewhere and the Collateral need not be located at the place of disposition.
Coast may directly or through any affiliated company purchase or lease any
Collateral at any such public disposition, and if permissible under
applicable law, at any private disposition. Any sale or other disposition of
Collateral shall not relieve Borrower of any liability Borrower may have if
any Collateral is defective as to title or physical condition or otherwise at
the time of sale;

            (g)   Demand payment of, and collect any Receivables and General
Intangibles comprising Collateral and, in connection therewith, Borrower
irrevocably authorizes Coast to endorse or sign Borrower's name on all
collections, receipts, instruments and other documents, to take possession of
and open mail addressed to Borrower and remove therefrom payments made with
respect to any item of the Collateral or proceeds thereof, and, in Coast's
sole discretion, to grant extensions of time to pay, compromise claims and
settle Receivables and the like for less than face value; and

            (h)   Demand and receive possession of any of Borrower's federal
and state income tax returns and the books and records utilized in the
preparation thereof or referring thereto.

      All attorneys' fees, expenses, costs, liabilities and obligations
incurred by Coast (including attorneys' fees and expenses incurred in
connection with bankruptcy) with respect to the foregoing shall be due from
the Borrower to Coast on demand. Coast may charge the same to Borrower's loan
account, and the same shall thereafter bear interest at the same rate as is
applicable to the Term Loan. Without limiting any of Coast's rights and
remedies, from and during the occurrence of any Event of Default, the
interest rate applicable to the Obligations shall be increased by an
additional three percent per annum.

      9.3   STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS. Borrower and
Coast agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable:

            (a)   Notice of the sale is given to Borrower at least seven (7)
days prior to the sale, and, in the case of a public sale, notice of the sale
is published at least seven (7) days before the sale in a

non-specific terms;

            (c)   The sale is conducted at a place designated by Coast, with

or wire transfer is required; and

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

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

      9.4   POWER OF ATTORNEY. Borrower grants to Coast an irrevocable power
of attorney coupled with an interest, authorizing and permitting Coast
(acting through any of its employees, attorneys or agents) at any time, at
its option, but without obligation, with or without notice to Borrower, and
at Borrower's expense, to do any or all of the following, in Borrower's name
or otherwise, but Coast agrees to exercise the following powers in a
commercially reasonable manner:

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

contemplated under this Agreement, and all other present and future
agreements;

            (b)   After and during the continuance of an Event of Default,

proceeds of Collateral; endorse the name of Borrower upon any instruments, or
documents, evidence of payment or Collateral that may come into Coast's
possession;

            (e)   After and during the continuance of an Event of Default,
endorse all checks and other forms of remittances received by Coast;

            (f)   After and during the continuance of an Event of Default,

take any action or pay any sum required of Borrower pursuant to this
Agreement and any other present or future agreements.

    Coast Business Credit              Term Loan and Security Agreement
_____________________________________________________________________________


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

      9.5   APPLICATION OF PROCEEDS. All proceeds realized as the result of
any sale of the Collateral pursuant to Coast's exercise of its remedies shall
be applied by Coast first to the costs, expenses, liabilities, obligations
and attorneys' fees incurred by Coast in the exercise of its rights under
this Agreement, second to the interest due upon any of the Obligations, and
third to the principal installments on the Term Loan in inverse order of
maturity. Any surplus shall be paid to Borrower or other persons legally
entitled thereto; Borrower shall remain liable to Coast for any deficiency.
If, Coast, in its sole discretion, directly or indirectly enters into a
deferred payment or other credit transaction with any purchaser at any sale
of Collateral, Coast shall have the option, exercisable at any time, in its
sole discretion, of either reducing the Obligations by the principal amount
of purchase price or deferring the reduction of the Obligations until the
actual receipt by Coast of the cash therefor.

      9.6   REMEDIES CUMULATIVE. In addition to the rights and remedies set
forth in this Agreement, Coast shall have all the other rights and remedies
accorded a secured party in equity, under the Code, and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Coast and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise
by Coast of one or more of its rights or remedies shall not be deemed an
election, nor bar Coast from subsequent exercise or partial exercise of any
other rights or remedies. The failure or delay of Coast to exercise any
rights or remedies shall not operate as a waiver thereof, but all rights and
remedies shall continue in full force and effect until all of the Obligations
have been indefeasibly paid and performed.

10.      GENERAL PROVISIONS

      10.1  INTEREST COMPUTATION. In computing interest on the Obligations,
all checks, wire transfers and other items of payment received by Coast
(including payment of the Obligations in full) shall be deemed applied by
Coast on account of the Obligations after receipt by Coast of immediately
available funds, and, for purposes of the foregoing, any such funds received
in the bank account designated by Coast during Coast's normal business hours,
shall be deemed received on the day they are received PROVIDED, HOWEVER, if
in the future Coast's standard operating procedure should change, for a
majority of Coast's borrowers by numbers, with respect to deeming items of
payment received on the same day they are received during normal business
hours, Borrower agrees to abide by such change. Coast shall not, however, be
required to credit Borrower's account for the amount of any item of payment
which is unsatisfactory to Coast in its sole discretion, and Coast may charge
Borrower's loan account for the amount of any item of payment which is
returned to Coast unpaid.

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


                                      15

<PAGE>

    Coast Business Credit              Term Loan and Security Agreement
_____________________________________________________________________________


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

      10.4  MONTHLY ACCOUNTINGS. Coast shall provide Borrower monthly with an
account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Coast), unless Borrower
notifies Coast in writing to the contrary within thirty (30) days after each
account is rendered, describing the nature of any alleged errors or omissions.

      10.5  NOTICES. All notices to be given under this Agreement shall be in
writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, facsimile or certified mail return
receipt requested, addressed to Coast or Borrower at the addresses shown in
the heading to this Agreement, or at any other address designated in writing
by one party to the other party. Notices to Coast shall be directed to the
Commercial Finance Division, to the attention of the Division Manager or the
Division Credit Manager. All notices shall be deemed to have been given upon
delivery in the case of notices personally delivered, faxed (at time of
confirmation of transmission), or at the expiration of one (1) Business Day
following delivery to the private delivery service, or two (2) Business Days
following the deposit thereof in the United States mail, with postage prepaid.

      10.6  SEVERABILITY. Should any provision of this Agreement be held by
any court of competent jurisdiction to be void or unenforceable, such defect
shall not affect the remainder of this Agreement, which shall continue in
full force and effect.

      10.7  INTEGRATION. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement with respect to the Term Loan between
Coast and supersede all prior and contemporaneous negotiations and oral
representations and agreements, all of which are merged and integrated in
this Agreement. THERE ARE NO ORAL UNDERSTANDINGS, REPRESENTATIONS OR
AGREEMENTS BETWEEN THE PARTIES WHICH ARE NOT SET FORTH IN THIS AGREEMENT OR
IN OTHER WRITTEN AGREEMENTS SIGNED BY THE PARTIES IN CONNECTION HEREWITH.

      10.8  WAIVERS. The failure of Coast at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or
any other present or future agreement between Borrower and Coast shall not
waive or diminish any right of Coast later to demand and receive strict
compliance therewith. Any waiver of any Default shall not waive or affect any
other Default, whether prior or subsequent, and whether or not similar. None
of the provisions of this Agreement or any other agreement now or in the
future executed by Borrower and delivered to Coast shall be deemed to have
been waived by any act or knowledge of Coast or its agents or employees, but
only by a specific written waiver signed by an authorized officer of Coast
and delivered to Borrower. Borrower waives demand, protest, notice of protest
and notice of default or dishonor, notice of payment and nonpayment, release,
compromise, settlement, extension or renewal of any commercial paper,
instrument, account, General Intangible, document or guaranty at any time
held by Coast on which Borrower is or may in any way be liable, and notice of
any action taken by Coast, unless expressly required by this Agreement.

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

      10.10 AMENDMENT. The terms and provisions of this Agreement may not be
waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Coast.

      10.11 TIME OF ESSENCE. Time is of the essence in the performance by
Borrower and Coast of each and every obligation under this Agreement.

      10.12 ATTORNEYS FEES, COSTS AND CHARGES. Borrower shall reimburse Coast
for all attorneys' fees (including attorneys' fees and expenses incurred
pursuant to bankruptcy) and all filing, recording, search, title insurance,
appraisal, audit, and other costs incurred by Coast, pursuant to, or in
connection with, or relating

to this Agreement (whether or not a lawsuit is filed), including, but not
limited to, any attorneys' fees and costs (including attorneys' fees and

interest in, the Collateral; and otherwise represent Coast in any litigation

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

      10.13 BENEFIT OF AGREEMENT. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Coast; provided,
however, that Borrower may not assign or transfer any of its rights under
this Agreement without the prior written consent of Coast, and any prohibited
assignment shall be void. No consent by Coast to any assignment shall release
Borrower from its liability for the Obligations. Coast may assign its rights
and delegate its duties hereunder without the consent of Borrower. Coast
reserves the right to syndicate all or a portion of the transaction created
herein or sell, assign, transfer, negotiate, or grant participations in all
or any part of, or any interest in Coast's rights and benefits hereunder. In
connection with any such syndication, assignment or participation, Coast may
disclose all documents and information which Coast now or hereafter may have
relating to Borrower or Borrower's business. To the extent that Coast assigns
its rights and obligations hereunder to a third Person, Coast thereafter
shall be released from such assigned obligations to Borrower.

      10.14 PUBLICITY. Coast and Borrower are hereby authorized, at their own
expense, to issue appropriate press releases and to cause a tombstone to be
published announcing the consummation of this transaction and the aggregate
amount thereof.

      10.15 PARAGRAPH HEADINGS; CONSTRUCTION. Paragraph headings are only
used in this Agreement for convenience. Borrower and Coast acknowledge that
the headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe,
limit, define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between
the parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Coast or Borrower under any
rule of construction or otherwise.

      10.16 GOVERNING LAW; JURISDICTION; VENUE. This Agreement and all acts
and transactions hereunder and all rights and obligations of Coast and
Borrower shall be governed by the internal laws of the State of California,
without regard to its conflicts of law principles. As a material part of the
consideration to Coast to enter into this Agreement, Borrower (a) agrees that
all actions and proceedings relating directly or indirectly to this Agreement
shall, at Coast's option, be litigated in courts located within California,
and that the exclusive venue therefor shall be Los Angeles County; (b)
consents to the jurisdiction and venue of any such court and consents to
service of process in any such action or proceeding by personal delivery or
any other method permitted by law; and (c) waives any and all rights Borrower
may have to object to the jurisdiction of any such court, or to transfer or
change the venue of any such action or proceeding.

      10.17 MUTUAL WAIVER OF JURY TRIAL. BORROWER AND COAST EACH HEREBY WAIVE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING

      10.18 CONFIDENTIALITY. Coast will maintain the confidentiality of any
non-public information marked as confidential and relating to the business
operations and methodology of Borrower and financial performance of Borrower
("Borrower Information") provided to Coast solely by the Borrower as required

unless, prior to such disclosure, Coast obtains an executed acknowledgment
binding such party to maintain the confidentiality of the information,
prohibiting its disclosure except for the purposes permitted under this
Agreement, and agreeing that the information may not be used to compete with
the Borrower in any way. In the event Coast receives a subpoena or other
process for any Borrower Information, it will immediately give notice in
writing of the subpoena or other process, including a copy thereof, to
Borrower.

                                         actual number of days elapsed. The
                                         interest rate applicable to the Term
                                         Loan shall be adjusted monthly as of
                                         the first day of each month, and the
                                         interest to be charged for each
                                         month shall be based on the highest
                                         Prime Rate in effect during the
                                         prior month, but in no event shall
                                         the rate of interest charged on the
                                         Term Loan in any month be less than
                                         8% per annum.

      SECTION 3.2 -     LOAN FEE:        One-half percent (.50%) of the Loan
                                         Amount payable on the Closing Date
                                         with an additional one-quarter
                                         percent (.25%) of the Loan Amount to
                                         be paid on the first anniversary of

                                         to be fully earned on the Closing
                                         Date. The fees payable pursuant to
                                         this provision will survive
                                         notwithstanding an Early Termination
                                         of this Agreement pursuant to

      SECTION 6.10 -    MATERIAL ADVERSE
                        LITIGATION:      In  November  1998,  the  Company
                                         executed a term  sheet with the
                                         Palladin Group, L.P. ("Palladin")
                                         concerning  negotiations for a
                                         possible investment by Palladin in
                                         certain new classes of  securities
                                         of the Company  which,  at the time,
                                         the Company was  considering
                                         issuing to a certain fund managed by
                                         Palladin.  The Company subsequently
                                         terminated the negotiations in
                                         December 1998. An affiliate of
                                         Palladin,  Halifax  Fund,  L.P.
                                         ("Halifax"),  filed a lawsuit on or
                                         about  March 19,  1999 in San Diego
                                         Superior  Court  alleging that the
                                         termination  violated  duties owed
                                         by the Company to Halifax under the
                                         term sheet.  The lawsuit  seeks
                                         compensatory  damages of
                                         approximately $2.6  million and
                                         punitive  damages of  approximately
                                         $12.0  million.  The Company
                                         disputes  Halifax's  claim and
                                         intends to vigorously  defend itself
                                         against the lawsuit.

      SECTION 6.10 -    FUTURE CLAIMS AND
                        LITIGATION:      Borrower will promptly inform Coast
                                         in writing of any claim, proceeding,
                                         litigation or investigation in the
                                         future threatened or instituted by
                                         or against Borrower involving any
                                         single claim of Two Hundred Thousand

                                         involving Six Hundred Thousand
                                         Dollars ($600,000) or more in the

     facility.  To ensure that Lender is able to recover such costs and
     expenses, Borrower agrees that, notwithstanding any other provision of this
     Agreement, any Note or the Related Documents, Lender shall be entitled to
     collect the following facility charge, which Borrower hereby promises and
     agrees to pay:  BORROWER SHALL BE ASSESSED AN ANNUALIZED NON-USE FEE OF
     0.250% PAYABLE QUARTERLY IN ARREARS ON THE AVERAGE UNUSED BALANCE OF THE
     LINE OF CREDIT.

     LOAN ACCOUNT.  Lender shall maintain on its books a record of account in
     which Lender shall make entries for each Advance and such other debits and
     credits as shall be appropriate in connection with the Line of Credit.
     Lender shall provide Borrower with periodic statements of Borrower's
     account, which statements shall be considered to be correct and
     conclusively binding on Borrower unless Borrower notifies Lender to the
     contrary within thirty (30) days after Borrower's receipt of any such
     statement which Borrower deems to be incorrect.

COLLATERAL.  To secure payment of the Line of Credit and performance of all
other Loans, obligations and duties owed by Borrower to Lender under the
Related Documents, Borrower shall grant to Lender Security Interests in the
Collateral described in the Security Agreements executed by Borrower,
including without limitation Borrower's present and future Domestic Accounts,
general intangibles, and Inventory.  Lender's Security Interests in the
Collateral shall be continuing liens and shall include the proceeds and
products of the Collateral, including without limitation the proceeds of any
insurance.  With respect to the Collateral, Borrower agrees and represents
and warrants to Lender:

     PERFECTION OF SECURITY INTERESTS.  Borrower agrees to execute such
     financing statements and to take whatever other actions are requested by
     Lender to perfect and continue Lender's Security Interests in the
     Collateral.  Upon request of Lender, Borrower will deliver to Lender any
     and all of the documents evidencing or constituting the Collateral, and
     Borrower will note Lender's interest upon any and all Collateral if not
     delivered to Lender for possession by Lender.  Contemporaneous with the
     execution of this Agreement, Borrower will execute one or more UCC
     financing statements and any similar statements as may be required by
     applicable law, and will file such financing statements and all such
     similar statements in the appropriate location or locations.  Borrower
     hereby appoints Lender as its irrevocable attorney-in-fact for the purpose
     of executing any documents necessary to perfect or to continue any Security
     Interest in the Collateral.  Lender may at any time, and without further
     authorization from Borrower, file a carbon, photograph, facsimile, or other
     reproduction of any financing statement for use as a financing statement.
     Borrower will reimburse Lender for all expenses for the perfection,
     termination, and the continuation of the perfection of Lender's Security
     Interest in the Collateral. Borrower promptly will notify Lender of any
     change in Borrower's name including any change to the fictitious business
     names of Borrower. Borrower also promptly will notify Lender of any change
     in Borrower's  Social Security Number or Employer Identification Number.
     Borrower further agrees to notify Lender in writing prior to any change in
     address or location of Borrower's principal governance office or should
     Borrower merge or consolidate with any other entity.

     COLLATERAL RECORDS.  Borrower does now, and at all times hereafter shall,
     keep correct and accurate records of the Collateral, all of which records
     shall be available to Lender or Lender's representative upon demand for

     Accounts, Borrower agrees to keep and maintain such records as Lender may

     Borrower within 10 Business Days of Lender's receipt of a Borrowing Base

     Base set forth in such Borrowing Base Certificate, the Borrowing Base

     Borrowing Base Certificate.

     REPRESENTATIONS AND WARRANTIES CONCERNING ACCOUNTS.  With respect to the

     provided, however, such actions shall occur no more frequently than once
     per month.

     REPRESENTATIONS AND WARRANTIES CONCERNING INVENTORY.  With respect to the

     hereafter be stored with a bailee, warehouseman, or similar party without
     Lender's prior written consent, and, in such event, Borrower will

     or similar party to issue and deliver to Lender, in form acceptable to
     Lender, warehouse receipts in Lender's name evidencing the storage of

     frequently than once per month.

     REMITTANCE ACCOUNT.  Borrower agrees that Lender may at any time require
     Borrower to institute procedures whereby the payments and other proceeds of
     the Domestic Accounts shall be paid by the Account Debtors under a
     remittance account or lock box arrangement with Lender, or Lender's agent,
     or with one or more financial institutions designated by Lender.  Borrower
     further agrees that, if no Event of Default exists under this Agreement,

REPRESENTATIONS AND WARRANTIES.  Borrower represents and warrants to Lender, as

     properties and to transact the businesses in which it is presently engaged
     or presently proposes to engage.  Borrower also is duly qualified as a

     and all Related Documents by Borrower, to the extent to be executed,

     Borrower's financial condition subsequent to the date of the most recent
     financial statement supplied to Lender.  Borrower has no material
     contingent obligations except as disclosed in such financial statements.

     LEGAL EFFECT.  This Agreement constitutes, and any instrument or agreement
     required hereunder to be given by Borrower when delivered will constitute,
     legal, valid and binding obligations of Borrower enforceable against
     Borrower in accordance with their respective terms, except as such
     enforceability may be limited by applicable bankruptcy, insolvency,
     reorganization, moratorium or similar laws affecting the enforcement of
     creditors' rights generally.

     PROPERTIES.  Except for Permitted Liens, Borrower owns and has good title
     to all of Borrower's properties free and clear of all Security Interests,

     Safety Code, Section 25100, et seq., or other applicable state or
     Federal laws, rules, or regulations adopted pursuant to any of the
     foregoing. Except as disclosed to and acknowledged by Lender in writing,
     Borrower represents and warrants that:  (a) During the period of
     Borrower's ownership of the properties, there has been no use,
     generation, manufacture, storage, treatment, disposal, release or
     threatened release of any hazardous waste or substance by any person on,
     under, about or from any of the properties.  (b) Borrower has no
     knowledge of, or reason to believe that there has been:  (i) any use,
     generation, manufacture, storage, treatment, disposal, release, or
     threatened release of any hazardous waste or substance on, under, about
     or from the properties by any prior owners or occupants of any of the
     properties, or  (ii) any actual or threatened litigation or claims of
     any kind by any person relating to such matters. (c) Neither Borrower
     nor any tenant, contractor, agent or other authorized user of any of the

     regulations, and ordinances, including without limitation those laws,

     substances. Borrower hereby:  (a) releases and waives ay future claims
     against Lender for indemnity or contribution in the event Borrower
     becomes liable for cleanup or other costs under any such laws, and  (b)
     agrees to indemnify and hold harmless Lender against any and all claims,
     losses, liabilities, damages, penalties, and expenses which Lender may
     directly or indirectly sustain or suffer resulting from a breach of this
     section or as a consequence of any use, generation, manufacture,
     storage, disposal, release or threatened release of a hazardous waste or
     substance on the properties. The provisions of this section, including
     the obligation to indemnify, shall survive the payment of the
     Indebtedness and the termination or expiration of this Agreement and
     shall not be affected by Lender's acquisition of any interest in any of
     the properties, whether by foreclosure or otherwise.

     LITIGATION AND CLAIMS.  No litigation, claim, investigation, administrative
     proceeding or similar action (including those for unpaid taxes) against
     Borrower is pending or threatened, and no other event has occurred which
     may materially adversely affect Borrower's financial condition or
     properties, other than litigation, claims, or other events, if any, that
     have been disclosed to and acknowledged by Lender in writing.

     Borrower that are or were required to be filed, have been filed, and all
     taxes, assessments and other governmental charges have been paid in full,
     except those presently being or to be contested by Borrower in good faith
     in the ordinary course of business and for which adequate reserves have
     been provided.

     LIEN PRIORITY.  Unless otherwise previously disclosed to Lender in writing,
     Borrower has not, other than Permitted Liens, entered into or granted any
     Security Agreements, or permitted the filing or attachment of any Security
     Interests on or affecting any of the Collateral directly or indirectly
     securing repayment of Borrower's Loan and Notes, that would be prior or
     that may in any way be superior to Lender's Security Interests and rights
     in and to such Collateral.

     BINDING EFFECT.  This Agreement, the Notes, all Security Agreements
     directly or indirectly securing repayment of Borrower's Loan and Notes and
     all of the Related Documents to which Borrower is a party are binding upon
     Borrower as well as upon Borrower's successors, representatives and
     assigns, and are legally enforceable in accordance with their respective
     terms, except as such enforceability may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium or similar laws
     affecting the enforcement of creditors' rights generally.

     COMMERCIAL PURPOSES.  Borrower intends to use the Loan proceeds solely for
     business or commercial related purposes.

     has designated otherwise in writing, this location is also the office or
     offices where Borrower keeps its records concerning the Collateral.

     the same manner and with the same functionality as the software does

     Borrower warrants and represents that the data-related user interface
     functions, data-fields, and data-related program instructions and functions

     above representations and warranties in extending Loan Advances to
     Borrower.  Borrower further agrees that the foregoing representations and

     effect until such time as Borrower's Indebtedness shall be paid in full, or

     whichever is the last to occur.

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

     FINANCIAL STATEMENTS.  Furnish Lender with, as soon as available, but in no
     event later than ninety (90) days after the end of each fiscal year, a
     consolidated balance sheet and income statement of Borrower and its
     subsidiaries for the year ended, audited by a certified public accountant
     satisfactory to Lender, and, as soon as available, but in no event later
     than forty-five (45) days after the end of each fiscal quarter, a
     consolidated balance sheet and income statement of Borrower and its
     subsidiaries for the period ended, prepared and certified as correct to the
     best knowledge and belief by Borrower's chief financial officer or other
     officer or person acceptable to Lender.  All financial reports required to
     be provided under this Agreement shall be prepared in accordance with
     generally accepted accounting principles, applied on a consistent basis,
     and certified by Borrower as being true and correct.

     ADDITIONAL INFORMATION.  Furnish such additional information and
     statements, lists of assets and liabilities, agings of receivables and
     payables, inventory schedules, budgets, forecasts, tax returns, and other
     reports with respect to Borrower's and its subsidiaries financial condition
     and business operations as Lender may reasonably request from time to time.

     FINANCIAL COVENANTS AND RATIOS.  Comply with the following covenants and
     ratios (measured with respect to Borrower and its subsidiaries on a
     consolidated basis):

          TANGIBLE NET WORTH.  Maintain a minimum Tangible Net Worth of not less
          than $6,500,000.00.

          NET WORTH RATIO.  Maintain a ratio of Total Debt to Tangible Net Worth
          of less than 2.00 TO 1.00.

          CURRENT RATIO.  Maintain a ratio of Current Assets to Current
          Liabilities in excess of 1.15 TO 1.00.

          EBITDA to Fixed Charges Ratio. Maintain a ratio of EBITDA to Fixed
          Charges of 1.50 TO 1.00

     The following provisions shall apply for purposes of determining compliance
     with the foregoing financial covenants and ratios: Such financial covenants
     and ratios will be calculated by Borrower as of the last day of each fiscal
     quarter, and such calculations shall be delivered to Lender pursuant to a
     Compliance Certificate (as required to be delivered by the paragraph above
     titled "Collateral Schedules") within 30 days after the end of each fiscal
     quarter. For the purpose of this Agreement, Tangible Net Worth shall be
     calculated as net worth plus Subordinated Debt, less net intangible assets.
     Total Debt for this calculation shall be defined as total Debt less
     Subordinated Debt.

     EBITDA TO FIXED CHARGES is calculated as the ratio of EDITDA, less cash

     depreciation and amortization.

     interest expense, including imputed interest on capital leases, and (iv)
     maintenance level capital expenditures, all of which shall be calculated on
     a pro-rata basis for the number of quarters used in the measurement period.
     Except as provided above, all computations made to determine compliance
     with the requirements contained in this paragraph shall be made in
     accordance with generally accepted accounting principles, applied on a
     consistent basis, and certified by Borrower as being true and correct.

     INSURANCE.  Maintain fire and other risk insurance, public liability
     insurance, and such other insurance as Lender may reasonably require with
     respect to Borrower's properties and operations, in form, amounts,
     coverages and with insurance companies reasonably acceptable to Lender.
     Borrower, upon request of Lender, will deliver to Lender from time to time
     the policies or certificates of insurance in form reasonably satisfactory
     to Lender, including stipulations that coverages will not be cancelled or
     diminished without at least ten (10) days' prior written notice to Lender.
     Each insurance policy also shall include an endorsement providing that
     coverage in favor of Lender will not be impaired in any way by any act,
     omission or default of Borrower or any other person.  In connection with
     all policies covering assets in which Lender holds or is offered a security
     interest for the Loans, Borrower will provide Lender with such loss payable
     or other endorsements as Lender may require.

     INSURANCE REPORTS.  Furnish to Lender, upon request of Lender, reports on
     each existing insurance policy showing such information as Lender may
     reasonably request, including without limitation the following:  (a) the
     name of the insurer;  (b) the risks insured;  (c) the amount of the policy;
     (d) the properties insured;  (e) the then current property values on the
     basis of which insurance has been obtained, and the manner of determining
     those values; and  (f) the expiration date of the policy.  In addition,
     upon request of Lender (however not more often than annually), Borrower
     will have an independent appraiser satisfactory to Lender determine, as
     applicable, the actual cash value or replacement cost of any Collateral.
     The cost of such appraisal shall be paid by Borrower.

     GUARANTIES.  Prior to disbursement of any Loan proceeds, furnish executed
     Guaranties of the Loans in favor of Lender, executed by the Guarantors
     named below, on Lender's forms, and in the amounts and under the conditions
     spelled out in those guaranties.

     OTHER AGREEMENTS.  Comply in all material respects with all terms and
     conditions of all other agreements relating to indebtedness in excess of
     $100,000 in the aggregate, whether now or hereafter existing, between
     Borrower and any other party and notify Lender immediately in writing of
     any default in connection with any other such agreements.

     LOAN PROCEEDS.  Use all Loan proceeds solely for Borrower's business
     operations, unless specifically consented to the contrary by Lender in
     writing. Lender hereby consents to the distribution by Borrower of an
     amount not to exceed $2,000,000 in Loan proceeds to ESSI at the Loan
     closing.

     TAXES, CHARGES AND LIENS.  Pay and discharge when due all of its
     indebtedness and obligations, including without limitation all assessments,
     taxes, governmental charges, levies and liens, of every kind and nature,
     imposed upon Borrower or its properties, income, or profits, prior to the
     date on which penalties would attach, and all lawful claims that, if
     unpaid, might become a lien or charge upon any of Borrower's properties,
     income, or profits.  Provided however, Borrower will not be required to pay
     and discharge any such assessment, tax, charge, levy, lien or claim so long
     as: (a) the legality of the same shall be contested in good faith by
     appropriate proceedings, and  (b) Borrower shall have established on its
     books adequate reserves with respect to such contested assessment, tax,
     charge, levy, lien, or claim in accordance with generally accepted
     accounting practices.  Borrower, upon demand of Lender, will furnish to
     Lender evidence of payment of the assessments, taxes, charges, levies,
     liens and claims and will authorize the appropriate governmental official
     to deliver to Lender at any time a written statement of any assessments,
     taxes, charges, levies, liens and claims against Borrower's properties,
     income, or profits.

     PERFORMANCE.  Perform and comply with all terms, conditions, and provisions
     set forth in this Agreement and in the Related Documents in a timely
     manner, and promptly notify Lender if Borrower learns of the occurrence of
     any event which constitutes an Event of Default under this Agreement or
     under any of the Related Documents.

     OPERATIONS.  Maintain executive and management personnel with substantially
     the same qualifications and experience as the present executive and
     management personnel; provide written notice to Lender of any change in
     executive and management personnel; conduct its business affairs in a
     reasonable and prudent manner and in compliance with all applicable
     federal, state and municipal laws, ordinances, rules and regulations
     respecting its properties, charters, businesses and operations, including
     without limitation, compliance with the Americans With Disabilities Act and
     with all minimum funding standards and other requirements of ERISA and
     other laws applicable to Borrower's employee benefit plans.

     INSPECTION.  Permit employees or agents of Lender at any reasonable time to
     inspect any and all Collateral for the Loan or Loans and Borrower's other
     properties and to examine or audit Borrower's books, accounts, and records
     and to make copies and memoranda of Borrower's books, accounts, and
     records.  If Borrower now or at any time hereafter maintains any records
     (including without limitation computer generated records and computer
     software programs for the generation of such records) in the possession of
     a third party, Borrower, upon request of Lender, shall notify such party to
     permit Lender free access to such records at all reasonable times and to
     provide Lender with copies of any records it may request, all at Borrower's
     expense.  Any such inspections or other Lender actions pursuant to the
     foregoing shall occur no more frequently than once per month.

     COMPLIANCE CERTIFICATE.  Unless waived in writing by Lender, provide Lender
     monthly as required by the paragraph above titled "Collateral Schedules"
     and at the time of each disbursement of Loan proceeds with a certificate
     executed by Borrower's chief financial officer, or other officer or person
     acceptable to Lender, certifying that the representations and warranties
     set forth in this Agreement are true and correct as of the date of the
     certificate and further certifying that, as of the date of the certificate,
     no Event of Default exists under this Agreement.

     ENVIRONMENTAL COMPLIANCE AND REPORTS.  Comply in all respects with all
     federal, state and local environmental protection laws, statutes,
     regulations and ordinances; not cause or permit to exist, as a result of an
     intentional or unintentional action or omission on its part or on the part
     of any third party, on property owned and/or occupied by Borrower, any
     environmental activity where damage may result to the environment, unless
     such environmental activity is pursuant to and in compliance with the
     conditions of a permit issued by the appropriate federal, state or local
     governmental authorities; furnish to Lender promptly and in any event
     within thirty (30) days after receipt thereof a copy of any notice,
     summons, lien, citation, directive, letter or other communication from any
     governmental agency or instrumentality concerning any intentional or
     unintentional action or omission on Borrower's part in connection with any
     environmental activity whether or not there is damage to the environment
     and/or other natural resources.

     ADDITIONAL ASSURANCES.  Make, execute and deliver to Lender such promissory
     notes, security agreements, financing statements, instruments, documents
     and other agreements as Lender or its attorneys may reasonably request to
     evidence and secure the Loans pursuant to the Security Documents and to
     perfect all Security Interests in Collateral.

RECOVERY OF ADDITIONAL COSTS.  If the imposition of or any change in any law,
rule, regulation or guideline, or the interpretation or application thereof
by any court or administrative or governmental authority (including any
request or policy not having the force of law) shall impose, modify or make
applicable any taxes (except U.S. federal, state or local income or franchise
taxes imposed on Lender), reserve requirements, capital adequacy requirements
or other obligations which would: (a) increase the cost to Lender for
extending or maintaining the credit facilities to which this Agreement
relates, (b) reduce the amounts payable to Lender under this Agreement or the
Related Documents, or  (c) reduce the rate of return on Lender's capital as a
consequence of Lender's obligations with respect to the credit facilities to
which this Agreement relates, then Borrower agrees to pay Lender such
additional amounts as will compensate Lender therefor, within five (5)
Business Days after Lender's written demand for such payment, which demand
shall be accompanied by an explanation of such imposition or charge and a
calculation in reasonable detail of the additional amounts payable by
Borrower, which explanation and calculations shall be conclusive in the
absence of manifest error.

NEGATIVE COVENANTS.  Borrower covenants and agrees with Lender that while
this Agreement is in effect, Borrower shall not, without the prior written
consent of Lender:

     INDEBTEDNESS AND LIENS.  Except as permitted by and subject to the
     paragraphs titled "Continuity of Operations", "Loans, Acquisitions and
     Guaranties" and "Additional Indebtedness and Liens" below: (a) Except for
     trade debt incurred in the normal course of business and indebtedness to
     Lender contemplated by this Agreement, create, incur or assume indebtedness
     for borrowed money, including capital leases,  (b) except as allowed as a
     Permitted Lien, sell, transfer, mortgage, assign, pledge, lease, grant a

     sell, lease or transfer its assets so long as it is not out of the
     ordinary course of business), or  (c) sell with recourse any of Borrower's
     Accounts, except to Lender.

     CONTINUITY OF OPERATIONS.  Except as permitted by and subject to the

     become obsolete, worn out or outdated, and (ii) Borrower may merge or
     consolidate with wholly-owned subsidiaries of ESSI, so long as ASI is the
     surviving entity, (c) subject to the paragraph below titled "Limitations on
     Loans, Distributions, Dividends and Salaries," pay any dividends on
     Borrower's stock (other than dividends payable in its stock), provided,
     however that notwithstanding the foregoing, but only so long as no Event of
     Default has occurred and is continuing or would result from the payment of
     dividends, if Borrower is a "Subchapter S Corporation" (as defined in the
     Internal Revenue Code of 1986, as amended), Borrower may pay cash dividends
     on its stock to its shareholders from time to time in amounts necessary to
     enable the shareholders to pay income taxes and make estimated income tax
     payments to satisfy their liabilities under federal and state law which
     arise solely from their status as shareholders of a Subchapter S
     Corporation because of their ownership of shares of stock of Borrower, or
     (d) purchase or retire any of Borrower's outstanding shares or alter or
     amend Borrower's capital structure.

     or assets other than in the ordinary course of business,  (b) purchase,
     create or acquire any interest in any other enterprise or entity, or (c)
     incur any obligation as surety or guarantor other than in the ordinary
     course of business or if such obligation is Subordinated Debt; except, in
     each such case: (i) extension of trade credit to customers or advances to
     employees in the ordinary course of business, (ii) Liquid Assets, (iii)
     purchase and acquisition of capital stock of existing subsidiaries,
     provided such capital stock is pledged to Lender as security for the
     Indebtedness (iv) loans and advances to the Foreign Subsidiaries, (v)
     Permitted Acquisitions, provided that the total consideration paid in
     connection with all Permitted Acquisitions does not exceed $1,000,000 per
     individual acquisition or $3,000,000 in the aggregate in any calendar year,
     and no Event of Default shall have occurred and be continuing at the time
     of such Permitted Acquisition nor any event which, with the giving of
     notice or the passage of time, or both, could constitute such an Event of
     Default, or (vi) Indebtedness and Guaranties pursuant to the Related
     Documents.

CESSATION OF ADVANCES.  Lender shall have no obligation to make Loan Advances or
to disburse Loan proceeds if:  (a) Borrower or any Guarantor is in default under
the terms of this Agreement or any of the Related Documents or any other
agreement that Borrower or any Guarantor has with Lender;  (b) Borrower or any
Guarantor becomes insolvent, files a petition in bankruptcy or similar
proceedings, or is adjudged a bankrupt, and such proceeding or petition shall
continue undismissed for 60 days or an order or decree approving any of the
foregoing shall be entered;  (c) there occurs a material adverse change in the
financial condition of Borrower and its subsidiaries on a consolidated basis, or
in the financial condition of ESSI, or in the value of the Collateral securing
the Loans or any material item thereof;  or (d) any Guarantor seeks, claims or
otherwise attempts to limit, modify or revoke such Guarantor's guaranty of the
Loan or any other loan with Lender.

PRIMARY BANKING RELATIONSHIP.  ASI and Yuma shall maintain their Primary Banking
Relationships with Lender, defined as the preponderance of their deposit
accounts, balances and loan activity.

INSPECTION.  First National Bank or a third party designated by First National
Bank, may conduct examinations of Borrower's books and records, semi-annually or
as deemed reasonably necessary by Lender; provided such examinations shall occur
no more frequently than once per month.  All costs, including all third party
costs, associated with the examinations shall be charged directly to Borrower.

EXPORT CREDIT INSURANCE.  Borrower shall cause the Foreign Eligible Accounts to
be insured as to principal and interest and in a form and content acceptable to
Lender by an Export Credit Insurance Policy and shall comply with all terms,
conditions and provisions of such Insurance to be complied with by Borrower and
the Foreign Subsidiaries.

CORPORATE GUARANTOR FINANCIAL INFORMATION.  ESSI shall provide Lender with
ESSI's annual Form 10-K as soon as available but in no event later than ninety
(90) days after the end of the applicable fiscal year, audited by a certified
public accountant reasonably satisfactory to Lender.  Borrower and each
Guarantor other than ESSI shall provide Lender with, as soon as available but in
no event later than thirty (30) days after the end of each calendar month, such
entity's  monthly internally prepared  financial statements. As soon as
available but in no event later than forty-five (45) days after the end of each
quarter, ESSI shall provide Lender with its Form 10-Q. In addition, ESSI shall
provide Lender with a signed copy of its current year federal income tax return
upon filing, together with all tax returns filed on behalf of Borrower and all
other Guarantors.  Should ESSI, Borrower or any other Guarantor file for an
extension of time to file its federal income tax return, a copy of the extension
shall be provided to Lender immediately upon filing.

UPSTREAMING PAYMENTS.  In addition to the permitted distribution to ESSI at the
Loan closing of an amount not to exceed $2,000,000, ASI shall have the right to
upstream profits to ESSI, in an amount not to exceed fifty percent (50%) of
ASI's annual "Net Profit After Tax plus Depreciation and Amortization"
(NPAT+DA), of which thirty percent (30%) of such amount may be distributed to
ESSI monthly.  Notwithstanding the foregoing, Lender, ASI and ESSI agree to
adjust the upstream payment on a quarterly basis, if necessary, to comply with
the fifty percent (50%) annual limitation, based on the most recent Form 10-Q.
The remaining twenty percent (20 %) will be held back from the monthly payment
until the annual audited financial statements are completed and the final
payment of the holdback amount is approved in writing by Lender. All upstream
payments to ESSI will reduce Subordinated Debt owed to ESSI, if any, with all
other upstream payments being treated as dividends.

In addition to the foregoing distributions, ASI shall be permitted to pay to
ESSI all required payments on: (a) accounts payable to ESSI, generated from the
purchases of inventory from ESSI by ASI in the ordinary course of business, as
per terms of sale to ASI, and (b) BioJect Leases entered into in the ordinary
course of business.

SUBORDINATED DEBT.  Prior to the closing of the Loan, Lender, ASI and ESSI will
mutually agree upon the amounts owing to ESSI by ASI, which amounts shall be
treated as Subordinated Debt hereunder, to be repaid to ESSI at the closing of
the Loan or in subsequent payments.

Notwithstanding the foregoing, ASI may make cash repayments to ESSI applicable
to Subordinated Debt only if in compliance with all terms, conditions, and
covenants of this Agreement and the Related Documents, but not in excess of the
fifty percent (50%) of NPAT+DA upstream payment limitation described above.

PROFITABILITY.  Borrower shall maintain consolidated net profit after tax
annually at all times as measured in accordance with GAAP ("General Accepted
Accounting Principles").  In addition, Borrower and its subsidiaries, on a
consolidated basis, may not have

more than two consecutive quarterly losses per fiscal year.

LIMITATIONS ON LOANS, DISTRIBUTIONS, DIVIDENDS AND SALARIES.  Except as
permitted by and subject to the paragraphs titled "Continuity of Operations" and
"Loans, Acquisitions and Guaranties" above, Borrower shall not declare or pay
any cash dividends or other distributions with respect to its capital stock, or
make any loans or cash payments to ESSI or its officers, directors, or
affiliates except: (a) Salaries and bonuses payable in the ordinary course of
business, (b) directors' fees not exceeding $10,000.00 per year, plus reasonable
out-of-pocket expenses related to the attendance of Board Meetings, and (c)
payments as described in the "Upstreaming Payments" provision, subject to the
limitations stated herewith.  Any payments or loans beyond these limitations
will require the express written consent of Lender.

ADDITIONAL INDEBTEDNESS AND LIENS.  In addition to the foregoing "Indebtedness
and Liens" provision, without the prior written consent of Lender, Borrower
shall not incur additional borrowed money or liens except for: (a) purchase
money liens securing indebtedness not exceeding $300,000 in the aggregate in any
fiscal year; (b) indebtedness with respect to BioJect Leases and any liens or
similar documentation with respect thereto reasonably necessary to evidence the
parties' rights and obligations under the BioJect Leases, (c) liens for capital
leases of equipment, fixtures or other personal property, which together provide
for aggregate lease payments of not more than $200,000 per fiscal year, (d)
indebtedness acquired in connection with Permitted Acquisitions or liens
securing such indebtedness, in an amount not to exceed $500,000 per calendar
year; provided that such liens secure only the assets so acquired, (e)
indebtedness and liens relating to Earn Out Obligations arising in connection
with Permitted Acquisitions, and (f) indebtedness which as of the date of this
Agreement has been disclosed to Lender in writing.

BORROWER FINANCIAL STATEMENTS.  In addition to the foregoing "Financial
Statements" provision, ESSI and Borrower (including Borrower's subsidiaries on a
consolidated basis) shall provide Lender with annual projections within thirty
(30) days after each fiscal year end. In addition, ESSI and, if applicable,
Borrower shall provide Lender with a CPA Management Letter within thirty (30)
days after each fiscal year end.

COMPLIANCE CERTIFICATE.  Notwithstanding the foregoing "Compliance Certificate"
provision, Borrower shall submit a compliance certificate with quarterly and
annual financials.

RIGHT OF SETOFF. Borrower authorizes Lender, to the extent permitted by
applicable law after the occurrence and during the continuance of any Event of
Default, to charge or setoff all sums owing on the Indebtedness against any and
all of Borrower's accounts with Lender (whether checking, savings, or any other
account), including without limitation all accounts held jointly with a third
party and all accounts Borrower may open in the future, excluding however all
IRA and Keogh accounts, and all trust accounts.

BIOJECT LEASES.  Notwithstanding anything to the contrary contained in this
Agreement or in any of the Related Documents, Borrower's use and exploitation of
the BioJects and related equipment/technology in the ordinary course of business
as permitted by the Bioject Leases shall not be restricted in any way
whatsoever.

EVENTS OF DEFAULT.  Each of the following shall constitute an Event of Default
under this Agreement:

     DEFAULT ON INDEBTEDNESS.  Failure of Borrower to make any payment on the
     Loans or other Indebtedness within five (5) days following the date such
     payment is due.

     OTHER DEFAULTS.  Failure of Borrower or any Grantor to comply with or to
     perform when due any other material term, obligation, covenant or condition
     contained in this Agreement or in any of the Related Documents.

     DEFAULT IN FAVOR OF THIRD PARTIES.  Should Borrower or any Grantor default
     under any loan, extension of credit, security agreement, purchase or sales
     agreement, or any other agreement, in favor of any other creditor or person
     that may materially affect any of Borrower's property or Borrower's or any
     Grantor's ability to repay the Loans or perform their respective
     obligations under this Agreement or any of the Related Documents.

     FALSE STATEMENTS.  Any warranty, representation or statement made or
     furnished to Lender by or on behalf of Borrower or any Grantor under this
     Agreement or the Related Documents is false or misleading in any material
     respect at the time made or furnished, or becomes false or misleading at
     any time thereafter.

     DEFECTIVE COLLATERALIZATION.  This Agreement or any of the Related
     Documents ceases to be in full force and effect (including failure of any
     Security Agreement to create a valid and perfected Security Interest) at
     any time and for any reason.

     INSOLVENCY.  The dissolution or termination of Borrower's existence as a
     going business, the insolvency of Borrower, the appointment of a receiver
     for any part of Borrower's property, any assignment for the benefit of
     creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Borrower,
     and such proceeding or petitions shall continue undismissed for 60 days, or
     an order or decree approving any of the foregoing shall be entered.

     CREDITOR OR FORFEITURE PROCEEDINGS.  Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Borrower, any creditor
     of any Grantor against any Collateral securing the Indebtedness, or by any
     governmental agency, and such proceeding shall continue undismissed for 60
     days or an order or decree approving any of the foregoing shall be entered.
     This includes a garnishment, attachment, or levy on or of any of Borrower's
     deposit accounts with Lender.  However, this Event of Default shall not
     apply if there is a good faith dispute by Borrower or Grantor, as the case
     may be, as to the validity or reasonableness of the claim which is the
     basis of the creditor or forfeiture proceeding, and if Borrower or Grantor
     gives Lender written notice of the creditor or forfeiture proceeding and
     furnishes reserves or a surety bond for the creditor or forfeiture
     proceeding satisfactory to Lender.

     EVENTS AFFECTING GUARANTOR.  Any of the preceding events occurs with
     respect to any Guarantor of any of the Indebtedness, or any Guarantor dies
     or becomes incompetent, or revokes or disputes the validity of, or
     liability under, any Guaranty of the Indebtedness.  Lender, at its option,
     may, but shall not be required to, permit the Guarantor's estate to assume
     unconditionally the obligations arising under the guaranty in a manner
     satisfactory to Lender, and, in doing so, cure the Event of Default.

     CHANGE IN OWNERSHIP.  Any change in ownership of twenty-five percent (25%)
     or more of the common stock of Borrower.

     ADVERSE CHANGE.  A material adverse change occurs in Borrower's and its
     subsidiaries' consolidated financial condition including, without
     limitation, Borrower and its subsidiaries, on a consolidated basis,
     incurring two (2) consecutive quarterly net losses in any fiscal year.

     RIGHT TO CURE.  If any default, other than a failure to make any payment on
     Indebtedness hereunder, is curable and if Borrower or

     Grantor, as the case may be, has not been given a notice of a similar
     default within the preceding twelve (12) months, it may be cured (and no
     Event of Default will have occurred) if Borrower or Grantor, as the case
     may be, after receiving written notice from Lender demanding cure of
     such default:  (a) cures the default within thirty (30) days, or (b) if
     the cure requires more than thirty (30) days, immediately initiates
     steps which Lender deems in Lender's reasonable discretion to be
     sufficient to cure the default and thereafter continues and completes
     all reasonable and necessary steps sufficient to produce compliance as
     soon as reasonably practical.

EFFECT OF AN EVENT OF DEFAULT.  If any Event of Default shall occur, except
where otherwise provided in this Agreement or the Related Documents, all
commitments and obligations of Lender under this Agreement or the Related
Documents immediately will terminate (including any obligation to make Loan
Advances or disbursements), and, at Lender's option, all Indebtedness
immediately will become due and payable, all without notice of any kind to
Borrower, except that in the case of an Event of Default of the type
described in the "Insolvency" subsection above, such acceleration shall be
automatic and not optional.  In addition, Lender shall have all the rights
and remedies provided in the Related Documents or available at law, in
equity, or otherwise.  Except as may be prohibited by applicable law, all of
Lender's rights and remedies shall be cumulative and may be exercised
singularly or concurrently.  Election by Lender to pursue any remedy shall
not exclude pursuit of any other remedy, and an election to make expenditures
or to take action to perform an obligation of Borrower or of any Grantor
shall not affect Lender's right to declare a default and to exercise its
rights and remedies.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Agreement:

     AMENDMENTS.  This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement.  No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     APPLICABLE LAW.  THIS AGREEMENT HAS BEEN DELIVERED TO LENDER AND ACCEPTED
     BY LENDER IN THE STATE OF CALIFORNIA.  IF THERE IS A LAWSUIT, BORROWER
     AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE JURISDICTION OF THE COURTS OF
     SAN DIEGO COUNTY, THE STATE OF CALIFORNIA.  LENDER AND BORROWER HEREBY
     WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION, PROCEEDING, OR
     COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER.
     (INITIAL HERE /S/ MB) THIS AGREEMENT SHALL BE GOVERNED BY AND
     CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA.

     CAPTION HEADINGS.  Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     CONSENT TO LOAN PARTICIPATION.  Borrower agrees and consents to Lender's
     sale or transfer, whether now or later, of one or more participation
     interests in the Loans to one or more purchasers, whether related or
     unrelated to Lender, in the aggregate amount of $5,000,000.  Lender may
     provide, without any limitation whatsoever, to any one or more purchasers,
     or potential purchasers, any information or knowledge Lender may have about
     Borrower or about any other matter relating to the Loan, and Borrower
     hereby waives any rights to privacy it may have with respect to such
     matters.  Borrower additionally waives any and all notices of sale of
     participation interests, as well as all notices of any repurchase of such
     participation interests.  Borrower also agrees that the purchasers of any
     such participation interests will be considered as the absolute owners of
     such interests in the Loans and will have all the rights granted under the
     participation agreement or agreements governing the sale of such
     participation interests.  Borrower further waives all rights of offset or
     counterclaim that it may have now or later against Lender or against any
     purchaser of such a participation interest and unconditionally agrees that
     either Lender or such purchaser may enforce Borrower's obligation under the
     Loans irrespective of the failure or insolvency of any holder of any
     interest in the Loans.  Borrower further agrees that the purchaser of any
     such participation interests may enforce its interests irrespective of any
     personal claims or defenses that Borrower may have against Lender. Lender
     agrees to use diligent efforts to obtain such Loan participation.

     COSTS AND EXPENSES.  Borrower agrees to pay upon demand all of Lender's
     reasonable expenses, including without limitation reasonable attorneys'
     fees, incurred in connection with the preparation, execution, enforcement,
     modification and collection of this Agreement or in connection with the
     Loans made pursuant to this Agreement.  Lender may pay someone else to help
     collect the Loans and to enforce this Agreement, and Borrower will pay that
     amount.  This includes, subject to any limits under applicable law,
     Lender's reasonable attorneys' fees and Lender's other legal expenses,
     whether or not there is a lawsuit, including reasonable attorneys' fees for
     bankruptcy proceedings (including efforts to modify or vacate any automatic
     stay or injunction), appeals, and any anticipated post-judgment collection
     services.  Borrower also will pay any court costs, in addition to all other
     sums provided by law.

     NOTICES.  All notices required to be given under this Agreement shall be
     given in writing, may be sent by telefacsimile (unless otherwise required
     by law), and shall be effective when actually delivered or when deposited
     with a nationally recognized overnight courier or deposited in the United
     States mail, first class, postage prepaid, addressed to the party to whom
     the notice is to be given at the address shown above.  Any party may change
     its address for notices under this Agreement by giving formal written
     notice to the other parties, specifying that the purpose of the notice is
     to change the party's address.  To the extent permitted by applicable law,
     if there is more than one Borrower, notice to ASI will constitute notice to
     all Borrowers.  For notice purposes, Borrower will keep Lender informed at
     all times of Borrower's current address(es).

     SEVERABILITY.  If a court of competent jurisdiction finds any provision of
     this Agreement to be invalid or unenforceable as to any person or
     circumstance, such finding shall not render that provision invalid or
     unenforceable as to any other persons or circumstances.  If feasible, any
     such offending provision shall be deemed to be modified to be within the
     limits of enforceability or validity; however, if the offending provision
     cannot be so modified, it shall be stricken and all other provisions of
     this Agreement in all other respects shall remain valid and enforceable.

     SUBSIDIARIES AND AFFILIATES OF BORROWER.  Under no circumstances shall this
     Agreement be construed to require Lender to make any Loan or other
     financial accommodation to any subsidiary or affiliate of Borrower.

     SUCCESSORS AND ASSIGNS.  All covenants and agreements contained by or on
     behalf of Borrower shall bind its successors and assigns and shall inure to
     the benefit of Lender, its successors and assigns.  Borrower shall not,
     however, have the right to assign its rights under this Agreement or any
     interest therein, without the prior written consent of Lender.

     SURVIVAL.  All warranties, representations, and covenants made by Borrower
     in this Agreement or in any certificate or other instrument delivered by
     Borrower to Lender under this Agreement shall be considered to have been
     relied upon by Lender and will survive the making of the Loan and delivery
     to Lender of the Related Documents, regardless of any investigation made by
     Lender or on Lender's behalf.

     TIME IS OF THE ESSENCE.  Time is of the essence in the performance of this
     Agreement.

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

     WAIVER.  Lender shall not be deemed to have waived any rights under this
     Agreement unless such waiver is given in writing and signed by Lender.  No
     delay or omission on the part of Lender in exercising any right shall
     operate as a waiver of such right or any other right.  A waiver by Lender
     of a provision of this Agreement shall not prejudice or constitute a waiver
     of Lender's right otherwise to demand strict compliance with that provision
     or any other provision of this Agreement.  No prior waiver by Lender, nor
     any course of dealing between Lender and Borrower, or between Lender and
     any Grantor, shall constitute a waiver of any of Lender's rights or of any
     obligations of Borrower or of any Grantor as to any future transactions.
     Whenever the consent of Lender is required under this Agreement, the
     granting of such consent by Lender in any instance shall not constitute
     continuing consent in subsequent instances where such consent is required,
     and in all cases such consent may be granted or withheld in the reasonable
     discretion of Lender.

     SEPARATE LOANS.  The parties acknowledge that notwithstanding the
     classification of ASI, Sistemas and ASM collectively as Borrower in this
     Agreement, ASI is the sole payor under the terms of the Note executed by
     ASI in favor of Lender (the "ASI Note"), and Sistemas and ASM are the sole
     payors under the terms of the Note (Pagare) executed by Sistemas and ASM in
     favor of Lender (the "Pagare"). The repayment obligations of ASI with
     respect to the Pagare Note arise solely by virtue of ASI's status as
     Guarantor thereof.

     PAGARE INTEREST RATE OPTION.  Notwithstanding the absence of a reference to
     the Libor Option in the Pagare, Sistemas and ASM shall have the same rights
     to elect alternative interest rates with respect to Loan Advances under the
     Pagare as are granted to ASI under the ASI Note, subject to the Advance
     Limitations and other restrictions and limitations set forth in the ASI
     Note.

     PAGARE DEMAND PROVISION.  Notwithstanding that the terms of the Pagare
     provide that the Pagare shall be payable on demand, so long as no Event of
     Default has occurred and is continuing under the terms of this Agreement,
     the Pagare or any of the other Related Documents, no demand for the
     repayment of principal shall be made by Lender under the terms of the
     Pagare until June 30, 2001, the maturity date of the ASI Note, at which
     time the entire unpaid principal balance of the Pagare, all accrued and
     unpaid interest thereon and all other amounts due under the terms of this
     Agreement and the other Related Documents shall be immediately due and
     payable.

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

PRINCIPAL AMOUNT: $5,000,000.00 INITIAL RATE: 8.00%  DATE OF NOTE: JUNE 30, 1999



PROMISE TO PAY. AGRICULTURAL SUPPLY, INC., A DELAWARE CORPORATION ("BORROWER")
PROMISES TO PAY TO FIRST NATIONAL BANK ("LENDER"), OR ORDER, IN LAWFUL MONEY OF
THE UNITED STATES OF AMERICA, THE PRINCIPAL AMOUNT OF FIVE MILLION & 00/100
DOLLARS ($5,000,000.00) OR SO MUCH AS MAY BE OUTSTANDING, TOGETHER WITH INTEREST
ON THE UNPAID OUTSTANDING PRINCIPAL BALANCE OF EACH ADVANCE. INTEREST SHALL BE
CALCULATED FROM THE DATE OF EACH ADVANCE UNTIL REPAYMENT OF EACH ADVANCE.

PAYMENT. BORROWER WILL PAY THIS LOAN IN ONE PAYMENT OF ALL OUTSTANDING PRINCIPAL
PLUS ALL ACCRUED UNPAID INTEREST ON JUNE 30, 2001. IN ADDITION, BORROWER WILL
PAY REGULAR MONTHLY PAYMENTS OF ACCRUED UNPAID INTEREST BEGINNING AUGUST 1,
1999, AND ALL SUBSEQUENT INTEREST PAYMENTS ARE DUE ON THE SAME DAY OF EACH MONTH
AFTER THAT. The annual interest rate for this Note is computed on a 365/360
basis; that is, by applying the ratio of the annual interest rate over a year of
360 days, multiplied by the outstanding principal balance, multiplied by the
actual number of days the principal balance is outstanding. Borrower will pay
Lender at Lender's address shown above or at such other place as Lender may
designate in writing. Unless otherwise agreed or required by applicable law,
payments will be applied first to any unpaid collection costs and any late
charges, then to any unpaid interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in an index which is the Prime Rate (the "Prime
Index"). This is the rate Lender announces from time to time as its Prime Rate,
which generally is the rate Lender charges, or would charge, on 90-day unsecured
loans to the most creditworthy corporate customers. This rate may not be the
lowest rate available from Lender at any given time. Lender will tell Borrower
the current Prime Index rate upon Borrower's request. Borrower understands that
Lender may make loans based on other rates as well. The interest rate change
will not occur more often than each day. THE PRIME INDEX CURRENTLY IS 7.750%.
THE INTEREST RATE TO BE APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS NOTE
WILL BE AT A RATE OF 0.250 PERCENTAGE POINTS OVER THE PRIME INDEX, RESULTING IN
AN INITIAL RATE OF 8.00%. NOTICE: Under no circumstances will the interest rate
on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT PENALTY; MINIMUM INTEREST CHARGE. Borrower agrees that all loan fees
and other prepaid finance charges are earned fully as of the date of the loan
and will not be subject to refund upon early payment (whether voluntary or as a
result of default), except as otherwise required by law. In any event, even upon
full prepayment of this Note, Borrower understands that Lender is entitled to a
MINIMUM INTEREST CHARGE OF $100.00. UPON PREPAYMENT OF THIS NOTE, LENDER IS
ENTITLED TO THE FOLLOWING PREPAYMENT PENALTY: UPON ANY PREPAYMENT OF A LIBOR
OPTION BALANCE UNDER THIS NOTE, BORROWER WILL BE SUBJECT TO BREAKAGE COSTS FOR
LIBOR OPTIONS AS A PREPAYMENT PENALTY. Other than Borrower's obligation to pay
any minimum interest charge and prepayment penalty, Borrower may pay all or a
portion of the amount owed earlier than the date it is due. Early payments will
not, unless agreed to by Lender in writing, relieve Borrower of Borrower's
obligation to continue to make payments of accrued unpaid interest. Rather, they
will reduce the principal balance due.

LATE CHARGE. If a payment is 10 DAYS OR MORE LATE, Borrower will be charged
5.000% OF THE UNPAID PORTION OF THE REGULARLY SCHEDULED PAYMENT OR $10.00,
WHICHEVER IS GREATER.

DEFAULT. Borrower will be in default if upon the occurrence and during the
continuance of any "Event of Default" as defined in that certain Loan Agreement
between Lender and Borrower dated as of the date hereof (the "Loan Agreement").

DISHONORED ITEM FEE. Borrower will pay a fee to Lender of $20.00 if Borrower
makes a payment on Borrower's loan and the check or preauthorized charge with
which Borrower pays is later dishonored.

RIGHT OF SETOFF. The paragraph titled "Right of Setoff" contained in the Loan
Agreement by this reference is made a part of this Note just as if such
paragraph had been fully set forth in this Note.

LINE OF CREDIT. This Note references a revolving line of credit provided to
Borrower by Lender pursuant to this Note and the Loan Agreement. All provisions,
terms and conditions of the Loan Agreement by this reference are made a part of
this Note just as if such provisions, terms and conditions had been fully set
forth in this Note.

INTEREST RATE OPTIONS. THE FOLLOWING INTEREST RATE OPTIONS ARE AVAILABLE UNDER
THIS AGREEMENT:

(A) Default Rate Option. The interest rate margin and Prime Index described in
the "Variable Interest Rate" paragraph above (the "Default Rate").

(B) Libor Option. The interest rate under this option is subject to change from
time to time based upon changes in the Libor Index (defined below). The interest
rate applied will be at a rate of 275 basis points over the Libor Index, but not
less than an interest rate of 7.75% per annum and will be fixed for a period of
three months. For purposes of this paragraph, the Libor Index will be based upon
London Interbank Offered Rates (LIBOR) as published in the Wall Street Journal
Money Rates Section, utilizing the three month rate (the "Libor Index"). The
Libor Index is not necessarily the lowest rate charged by Lender on its loans.
If the Libor Index becomes unavailable during the term of this loan, Lender may
designate the Prime Index as a substitute after notice to Borrower. Lender will
tell Borrower the current Libor Index rate upon Borrower's request. Borrower
understands that Lender may make loans based on other rates as well. The
interest rate charged will not be changed more often than each quarter, on the
first day of the month. Advances under the Libor Option

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

are subject to "Advance Limitations".

Provided Borrower is not in default under this Note, Borrower may designate in
advance which of the above interest rate indices shall be applicable to all or
any portion of the principal balance under this Note. In the absence of any such
designation the Default Rate will be in effect. Thereafter, unpaid principal
balances under this Note may be converted (at the end of an interest period if
the Libor Index is used to determine the interest rate therefor) to another of
the above interest rate Options, or continued for an additional interest period,
when applicable, as designated by Borrower in advance; and in the absence of
sufficient advance designation as to conversion to or continuation of a Libor
Index, the Libor Index shall be converted to the Prime Index. Notwithstanding
the foregoing, a Libor Index may not be elected for any principal balance under
this Note, nor may any conversion to or continuation of a Libor Index be
elected, if the interest period thereof would extend beyond the maturity date of
this Note. All payments with respect to principal shall be allocated first to
principal bearing interest at the Default Rate and then to principal bearing
interest under the Libor Option.

ADVANCE LIMITATIONS. Advances priced under the Libor Option must be a minimum of
$500,000.00 each and increasing in increments of $100,000.00 above $500,000.00.

LENDER'S RIGHTS. An exhibit, titled "LENDER'S RIGHTS," is attached to this Note
and by this reference is made a part of this Note just as if all the provisions,
terms and conditions of the Exhibit had been fully set forth in this Note.

GENERAL PROVISIONS. Lender may delay or forgo enforcing any of its rights or
remedies under this Note without losing them. Borrower and any other person who
signs, guarantees or endorses this Note, to the extent allowed by law, waive any
applicable statute of limitations, presentment, demand for payment, protest and
notice of dishonor. Upon any change in the terms of this Note, and unless
otherwise expressly stated in writing, no party who signs this Note, whether as
maker, guarantor, accommodation maker or endorser, shall be released from
liability. All such parties agree that Lender may renew or extend (repeatedly
and for any length of time) this Note, or release any party or guarantor or
collateral; or impair, fail to realize upon or perfect Lender's security
interest in the collateral; and take any other action deemed necessary by Lender
without the consent of or notice to anyone. All such parties also agree that
Lender may modify this Note without the consent of or notice to anyone other
than the party with whom the modification is made.

PRIOR TO SIGNING THIS NOTE, BORROWER READ AND UNDERSTOOD ALL THE PROVISIONS OF
THIS NOTE, INCLUDING THE VARIABLE INTEREST RATE PROVISIONS. BORROWER AGREES TO
THE TERMS OF THE NOTE AND ACKNOWLEDGES RECEIPT OF A COMPLETED COPY OF THE NOTE.
