but are not limited to, those discussed in "Risk Factors."
 
                                  THE COMPANY
 
     The Company designs, develops, manufactures and markets proprietary,
safety-enhanced, disposable medical products intended to protect healthcare
workers from the spread of infectious diseases such as AIDS and hepatitis. The
Company's first product line, the SafeSnap syringe, consists of a line of
single-use hypodermic syringes designed to reduce the risk of transmission of
blood borne diseases from accidental needlesticks. A SafeSnap syringe is similar
in appearance, size and manner of use to a standard (i.e., non-safety) syringe;
however, it incorporates patented retraction and encapsulation technology that
permits the isolation of the needle within the barrel of the syringe immediately
after use, thereby facilitating safe disposal. The SafeSnap product line
consists of four syringes which vary by size, needle length and gauge. The
SafeSnap syringe is also latex-free and will not cause adverse reactions in the
estimated 8-10% of patients and healthcare workers with allergies to latex. The
Company believes that the SafeSnap syringe is the only safety syringe currently
on the market that is latex-free. The Company has five additional safety
products under development: a winged butterfly set, an arterial-venous fistula
set, a blood gas syringe, a needleless vial adapter and a phlebotomy (blood
collection) device.
 
     An estimated 800,000 accidental needlesticks from syringes, catheters and
blood collection devices occur nationwide each year in hospital and clinic
settings with direct costs of up to $1,200 per incident, including treatment of
the wound, diagnostic tests and lost worker time and excluding long-term
treatment and liability costs. The spread of infectious diseases to nurses,
doctors, medical technicians and others through accidental needlesticks is a
matter of concern to the healthcare industry. Heightened awareness of the risk
of infection from accidental needlesticks and the substantial cost to healthcare
providers of complying with regulatory protocols when needlesticks occur have
led to growing demand for safe medical devices such as the Company's SafeSnap
syringes. In response to these concerns, healthcare regulations have been
promulgated by the Occupational Safety and Health Administration mandating that
"universal precautions" be observed to minimize exposure to blood and other body
fluids. In addition, several states have directed hospitals to develop programs
to track the effectiveness of safety devices and to develop guidelines for the
handling and disposal of "sharps" devices.
 
     According to industry reports, approximately 5.2 billion syringes were sold
in the United States in 1995. Although safety has increasingly become a concern
in the healthcare industry, safety syringes currently represent only a small
portion of the overall syringe market. Studies indicate that safety syringes
will become widely used during the next five years, capturing up to 80 percent
of the syringe market by the year 2001. The Company believes that its SafeSnap
syringe has the potential to capture a significant share of the overall syringe
market because of its advantages over standard and other competitive safety
syringes.
 
     The Company's objective is to become a leading designer, developer,
manufacturer and marketer of safety-enhanced medical products. Its business
strategy is to (i) increase its customer base through direct selling efforts and
establishing strategic distribution alliances, (ii) broaden its product lines by
applying its technology, manufacturing capabilities and market presence
developed with the SafeSnap syringe and
 
                                        3
<PAGE>   5
 
(iii) reduce per unit cost by increasing unit volume, completing the Company's
automation of assembly and printing processes and incorporating design
enhancements in production tooling.
 
     The Company has devoted a substantial portion of its efforts since its
formation to research and development and the establishment of its manufacturing
capabilities. From inception through April 30, 1996, the Company has incurred
approximately $3.4 million in research and development expenses and
approximately $10.8 million in pre-manufacturing and manufacturing costs,
including depreciation. In addition, as of April 30, 1996, the Company had
invested approximately $9.6 million in property and equipment. The Company
operates a 55,000 square foot vertically integrated manufacturing facility where
it designs and builds most of its high precision molds and prototypes. The
Company has established a high-speed, fully automated production line for the
molding, printing, assembly and packaging of the 3cc size SafeSnap syringe. The
Company also molds, prints and packages the remaining sizes at its facility.
Assembly of those sizes is currently performed by third-party subcontractors.
The Company will use a portion of the proceeds of this offering to implement
automation of the printing and assembly processes for those remaining syringe
sizes.
 
     The Company has recently expanded its direct sales force and distribution
channels. Since January 31, 1996, the Company has hired a Vice President of
Sales, area sales directors and a majority of its planned 24 member direct sales
force which will establish a presence in 24 major metropolitan areas in the
United States. The Company has also entered into a distribution partnership with
one of the largest medical products distributors in Asia to facilitate sales of
its products in Japan. In the five months ended June 30, 1996, net sales were
approximately $630,000, principally as a result of sales to the Company's
distributor in Japan and increased domestic sales, as compared to net sales of
$51,000 in the five months ended June 30, 1995.
 
     The Company was incorporated in California in 1991. Its offices are located
at 16825 Via Del Campo Court, San Diego, California 92127, and its telephone
number is (619) 674-7200.

                                  RISK FACTORS
 
     In evaluating an investment in the Common Stock being offered hereby,
investors should consider carefully, among other matters, the following risk
factors, as well as the other information contained in this Prospectus. An
investment in the Common Stock is speculative in nature, and involves a high
degree of risk.
 
UNCERTAINTY OF MARKET ACCEPTANCE; LIMITED CURRENT MARKET FOR SAFETY SYRINGES;
PREMIUM PRICING
 
     The use of safety medical products, including safety syringes, is a recent
development within the healthcare industry. While the market for syringes is
large, the market for safety syringes, including the Company's SafeSnap line of
products, has not yet been established. Safety syringes currently represent a
small portion of the domestic syringe market. In addition, the Company has not
completed the development of its safety winged butterfly set, arterial-venous
fistula set, blood gas syringe, needleless vial adapter or phlebotomy devices.
Therefore, the Company cannot be certain that any of these safety products will
be accepted by the healthcare industry. Market acceptance of the Company's
products will depend in large part on the Company's ability to demonstrate the
operational advantages, safety and cost effectiveness of its products as
compared to standard products and its competitors' safety products. Failure to
achieve market acceptance would have an adverse effect on the Company's
business, financial condition and results of operations.
 
     Manufacturing costs and prices for the Company's safety products are higher
than for their standard counterparts. While the Company believes that its
products can be cost effective on an actual use basis, prospective customers
must be convinced to pay premium prices for safety products. Increasing
sensitivity to healthcare costs, public interest in healthcare reform and
continuing pressure from Medicare, Medicaid and other payors to reduce costs in
the healthcare industry, as well as increasing competition from other safety
products, could affect the Company's ability to sell its products at premium
prices. In the event that the market will not accept premium prices for the
Company's products, the Company's sales and profits could be adversely affected.
The Company believes that its ability to increase its market share and operate
profitably in the long term will depend in part on its ability to reduce the
manufacturing costs of its products on a per unit basis through high volume
production using highly automated molding, printing and assembly systems. If the
Company is unable to reduce unit manufacturing costs, it may be unable to obtain
a significant share of the syringe market. Such a result would adversely affect
the Company's future results of operations. See "Business -- Sales, Marketing
and Distribution."
 
HISTORY OF OPERATING LOSSES; GOING CONCERN OPINION IN INDEPENDENT ACCOUNTANTS'
REPORT
 
     From its inception in 1991, the Company has been engaged principally in
research and development and the establishment of its manufacturing
capabilities. Product sales have not been significant to date, and the Company
has sustained losses in each year since its inception. Accordingly, the
Company's operations are subject to the risks inherent in the establishment of a
new business enterprise. The likelihood of the Company's success must be
considered in light of the problems, expenses, difficulties, complications and
delays frequently encountered in the marketing of new products. These include,
but are not limited to, manufacturing and marketing delays and expenses that may
exceed current estimates. See "Business."
 
     The Company sustained net losses of $7,482,000, $8,813,000 and $1,721,000
for the fiscal years ended January 31, 1995 and 1996 and the three months ended
April 30, 1996, respectively. Its accumulated deficit as of April 30, 1996 was
$23,698,000. The Company's independent accountants, Price Waterhouse LLP, have
included an explanatory paragraph in their report on the Company's financial
statements for 1996 which states that "the Company is in the development stage,
has incurred a cumulative net loss since inception and is dependent on
additional financing in order to continue its operations and execute its growth
strategy. These factors, among others, raise substantial doubt about the
Company's ability to continue as a going concern." The Company expects to
continue to incur losses during the near term due to the significant costs it
believes will be incurred in marketing the SafeSnap syringe and in developing
future products. There can be no assurance that the Company will achieve
profitability. See "Use of Proceeds," "Selected Financial Data," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Notes to Financial Statements."

<PAGE>   8
 
DEPENDENCE ON SAFESNAP; UNCERTAINTIES OF NEW PRODUCT DEVELOPMENT
 
     The Company is currently dependent upon sales of the SafeSnap syringe for
all its revenue, and market acceptance of the SafeSnap syringe has not yet been
demonstrated and is not assured. Factors adversely affecting the pricing of or
demand for the SafeSnap syringe will have a substantial impact upon the
Company's financial condition and its ability to introduce new products. Such
factors may include lack of market acceptance, competition from other products,
obsolescence as a result of the development of alternative drug delivery systems
and negative publicity. Furthermore, even if the SafeSnap syringe is successful,
the Company's success will also be dependent on new product development.
Although the Company is developing a variety of new safety products, there can
be no assurance that any of the Company's new products will be commercially
successful or that the Company will be able to recover the costs of developing,
testing, producing and marketing such products.
 
INTENSE COMPETITION; RISK OF TECHNOLOGICAL OBSOLESCENCE
 
     The market for syringe products is intensely competitive. The Company
believes that its ability to compete depends upon its continued product
innovation, the quality, convenience and reliability of its products, access to
distribution channels, the success of its direct sales strategy and patent
protection. The Company encounters significant competition both from large,
established medical device manufacturers and from smaller companies. Significant
competitors of the Company in the safety syringe market include Becton,
Dickinson and Company, Sherwood Medical (a division of American Home Products
Corporation) and Terumo Medical Corporation. Many companies have introduced
their own safety-enhanced syringes. Most of the Company's current and
prospective competitors have economic and other resources substantially greater
than the Company's and are well established as suppliers to the healthcare
industry. Several large, established competitors offer broad product lines and
have been successful in obtaining full-line contracts with a large number of
healthcare providers to supply a significant portion of their medical products.
There can be no assurance that the Company's competitors will not substantially
increase their resources devoted to the development, manufacture and marketing
of products that compete with the Company's products. The successful
implementation of such a strategy by one or more of the Company's competitors
could have a material adverse effect on the Company.
 
     The Company's initial focus on a single product line and technology makes
it vulnerable to the development of superior products and changes in technology.
The Company's proprietary technology relates to the safe injection or withdrawal
of fluids. To the extent that competing technologies may be developed which
provide a more effective or less intrusive method to achieve the same results,
the Company's technology could be rendered obsolete. Such obsolescence would
have an immediate and adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Competition."
 
LIMITED MANUFACTURING EXPERIENCE
 
     The Company has limited experience in manufacturing its products. The
Company is currently manufacturing the SafeSnap syringe and no other products.
The Company began manufacturing the 3cc SafeSnap syringe in fiscal 1994 and its
1cc, 5cc and 10cc syringe sizes in fiscal 1995. The Company has not yet begun to
function at full manufacturing capacity. Should orders increase, the Company may
experience manufacturing difficulties. For the Company to be successful, it must
manufacture the SafeSnap syringe in sufficient quantities and at a reasonable
cost while maintaining quality control standards. The Company does not have
sufficient manufacturing experience to be assured that it will meet these
requirements. In the course of making changes to its manufacturing processes as
it develops new products, the Company may encounter difficulties involving
product quality, product reliability, manufacturing costs, supplies and
personnel, which may lead to delays in production. There also can be no
assurance that the Company will be able to manufacture any of its proposed new
products. See "Business -- Manufacturing."
 
                                        7
<PAGE>   9
 
DEPENDENCE ON KEY SUPPLIERS
 
     Certain of the materials used to manufacture the Company's SafeSnap product
line are obtained from a sole supplier or a limited group of suppliers. For
example, the needles used in the Company's syringes are produced by a single
supplier located in Japan. In addition, as of the date of this Prospectus, a
majority of the Company's products are assembled by a third-party Maquiladora
operation in Mexico. Therefore, in addition to the normal risks attendant to a
sole supplier, such as the possibility of interruptions in supply and volatility
in prices, the cost of manufacturing the Company's syringes could be adversely
affected by changes in currency exchange rates. Regulatory requirements
applicable to medical device manufacturing can make substitution of suppliers
costly and time-consuming. While alternative suppliers are available, a change
in suppliers would cause an interruption of supply and possibly an increase in
costs. See "Business -- Manufacturing."
 
LIMITED SALES AND MARKETING EXPERIENCE
 
     The Company has experienced only limited sales to date. Historically, the
Company attempted to sell its products through distributors in the United
States. In 1996, the Company determined that the introduction of a new product
such as the Company's SafeSnap syringe would require the efforts and attention
of a direct sales force. Consequently, the Company shifted its marketing and
sales strategy to direct sales. To implement this strategy it hired a Vice
President of Sales and area sales directors, and it began hiring 24 sales
representatives in fiscal 1996. This sales force has only recently been
employed, and there can be no assurance that this strategy will be successful.
See "Business -- Sales, Marketing and Distribution."
 
LIMITED MANAGEMENT EXPERIENCE
 
     Although the Company intends to pursue a strategy of growth and will seek
to expand the market for its SafeSnap syringe and develop additional products,
the Company's management has had limited experience in effecting rapid expansion
and in managing operations which are more extensive than those presently
conducted. The Company's proposed expansion will be dependent, among other
things, on its ability to monitor operations, control costs, maintain quality
control standards and establish a successful marketing program. Although the
Company may seek to hire additional management with greater experience in the
operations of a medical products company, there can be no assurance that it will
be able to do so. See "Management."
 
PROPRIETARY PROTECTION; NEED TO DEVOTE ADDITIONAL RESOURCES TO PATENTS
 
     The Company's success will depend in part on its ability to protect its
proprietary rights. The Company owns the rights to three patents issued by the
United States Patent Office and has an exclusive paid-up license for an
additional patent with regard to its SafeSnap syringes. There can be no
assurance that the Company's patents will offer meaningful protection. There can
be no assurance that the Company's patents, if challenged, will be broad enough
to protect its proprietary position. In general, there has been substantial
litigation regarding patent and other intellectual property rights in the
medical device industry. Patent infringement litigation, which may be necessary
to enforce patents issued to or licensed by the Company, or to defend the
Company against claimed infringement of the rights of others, can be expensive
and may involve a substantial commitment of the Company's resources, thereby
diverting resources from other uses. Adverse determinations or settlements in
any such litigation could subject the Company to significant liabilities to
third parties, require the Company to seek licenses from third parties or
prevent the Company from manufacturing and selling its products, any of which
could have a material adverse effect on the Company's business. Additionally,
disputes may arise in the future with respect to the ownership of technology
developed by consultants or employees who were previously employed by other
companies. Patent infringement litigation and related litigation is inherently
uncertain and costly, and the claims and counterclaims which might be asserted
against the Company could, if successful, have a material adverse effect on the
Company and its finances. Moreover, the Company has not had sufficient financial
resources to expand its patent protection. To date, the Company has not filed
any patent applications for any products other than its SafeSnap syringe.
Accordingly, there can be no assurance that such products will be patentable.
See "Business -- Patents."
 
                                        8
<PAGE>   10
 
     In addition to its patents, the Company intends to rely upon unpatented
trade secrets and proprietary know-how and on the expertise of its employees.
Although the Company believes that it has in the past taken, and intends in the
future to take, appropriate steps to protect its unpatented proprietary rights,
including requiring that all of its employees and any third parties granted
access to the Company's proprietary technology enter into confidentiality
agreements with the Company, there can be no assurance that these measures will
be sufficient to protect the Company's rights against third parties. Likewise,
there can be no assurance that others will not independently develop or
otherwise acquire unpatented technologies or products similar or superior to
those of the Company.
 
GOVERNMENT REGULATION
 
     The testing, manufacture and sale of the Company's products are subject to
regulation by numerous governmental authorities, principally the FDA and
corresponding state and foreign regulatory agencies. Pursuant to the Federal
Food, Drug and Cosmetic Act (the "FDC Act"), and the regulations promulgated
thereunder, the FDA regulates the preclinical and clinical testing, manufacture,
labeling, distribution, and promotion of medical devices. Noncompliance with
applicable requirements can result in, among other things, fines, injunctions,
civil penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant premarket clearance or premarket
approval for devices, withdrawal of marketing clearances or approvals, and
criminal prosecution. The FDA also has the authority to request recall, repair,
replacement or refund of the cost of any device manufactured or distributed by
the Company.
 
     The Company will not be able to commence marketing or commercial sales in
the United States of new products under development until it receives clearance
or approval for such products from the FDA, which can be a lengthy, expensive
and uncertain process. Modifications to a device that is the subject of an
approved premarket approval ("PMA") application, its labeling or manufacturing
process may require approval by the FDA of PMA supplements or new PMAs. For any
devices that are cleared through the 510(k) process, modifications or
enhancements that could significantly affect safety or effectiveness, or
constitute a major change in the intended use of the device, will require new
510(k) submissions. Any devices manufactured or distributed by the Company
pursuant to FDA clearance or approvals are subject to pervasive and continuing
regulation by the FDA and certain state agencies. Manufacturers of medical
devices for marketing in the United States are required to adhere to applicable
regulations setting forth detailed Good Manufacturing Practices ("GMP")
requirements, which include testing, control and documentation requirements.
Manufacturers must also comply with Medical Device Reporting ("MDR")
requirements that a firm report to the FDA any incident in which its product may
have caused or contributed to a death or serious injury, or in which its product
malfunctioned and, if the malfunction were to recur, it would be likely to cause
or contribute to a death or serious injury. Labeling and promotional activities
are subject to scrutiny by the FDA and, in certain circumstances, by the Federal
Trade Commission. Current FDA enforcement policy prohibits the marketing of
approved medical devices for unapproved uses.
 
     The Company has obtained clearance from the FDA under Section 510(k) of the
FDC Act to market its SafeSnap line of syringes. The Company has made
modifications to its devices which the Company believes do not require the
submission of new 510(k) notices. There can be no assurance, however, that the
FDA would agree with any of the Company's determinations not to submit a new
510(k) notice for any of these changes or would not require the Company to
submit a new 510(k) notice for any of the changes made to the device. If the FDA
requires the Company to submit a new 510(k) notice for any device modification,
the Company may be prohibited from marketing the modified device until the
510(k) notice is cleared by the FDA. The Company currently has five product
lines under development, a winged butterfly set, an arterial-venous fistula set,
a blood gas syringe, a needleless vial adapter and a phlebotomy device. The
Company expects that these products will be subject to 510(k) premarket
clearance by the FDA (as opposed to the more costly and time consuming premarket
approval process) based upon the FDA's treatment of similar products on the
market. There can be no assurance, however, that the FDA will not require PMA
applications for one or more of these products under development. Further, there
can be no assurance that the Company will be able to obtain necessary regulatory
approvals or clearances for these products under development on a timely basis
or at all, and delays in receipt of or failure to receive such approvals or
clearances, the loss of
 
                                        9
<PAGE>   11
 
previously received clearances, limitations on intended use imposed as a
condition of such approvals or clearances, or failure to comply with existing or
future regulatory requirements could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
     The sale and distribution of the Company's medical devices outside the
United States are subject to foreign regulatory requirements that vary widely
from country to country. The time required to obtain approval or clearance
required by foreign countries may be longer or shorter than that required for
FDA approval or clearance and the requirements may differ. There can be no
assurance that the Company will be able to obtain necessary regulatory approvals
or clearances in countries in which it wants to introduce its products. See
"Business -- Government Regulation."
 
DEPENDENCE UPON KEY EMPLOYEES
 
     The success of the Company depends on the skills, experience and efforts of
its executive officers and certain marketing and technical personnel. The
Company is particularly dependent on the services of Matthew S. Mazur, the
founder, Chairman, President and Chief Executive Officer of the Company. The
Company is also dependent on the services of Scott M. Dolin, Vice President of
Operations, Carlos H. Manjarrez, Vice President of Research and Development,
Marshall Kerr, Vice President of Sales, and Louis Hernandez, Jr., Chief
Financial Officer. The loss of the services of Mr. Mazur or any of the Company's
other key employees could have an adverse effect on the Company.
 
     Mr. Mazur has an employment agreement with the Company which may be
terminated by either party upon 30 days' notice. The Company does not have an
employment agreement with any other key employee. See "Management."
 
NEED FOR QUALIFIED PERSONNEL
 
     In order to meet its business objectives, the Company will need to hire
additional marketing, engineering, manufacturing and sales personnel. The
Company will be required to compete for such personnel with companies having
greater financial and other resources. Since the future success of the Company
will be dependent, in part, upon its ability to attract and retain qualified
personnel, an inability to do so could have an adverse effect on the Company.
 
RISKS ASSOCIATED WITH INTERNATIONAL SALES
 
     In fiscal 1996 and for the first three months of fiscal 1997, international
sales represented approximately 66% and 86% of the Company's total revenues,
respectively. The Company intends to expand its sales outside the United States
and to enter markets, either directly or through distributors, that will require
significant management attention and financial resources. There can be no
assurance that the Company's efforts to increase its presence in international
markets will be successful or that such markets will prove to be viable. To the
extent that the Company is able to continue to successfully increase its foreign
sales, it will become increasingly subject to risks inherent in foreign trade,
including increased credit risk, customs duties and import quotas and other
trade restrictions, fluctuations in foreign currency exchange rates, shipping
delays, and international political, regulatory and economic developments, all
of which could have a material adverse effect on the Company. In addition, to
the extent that the Company establishes operations in foreign countries, there
can be no assurance that political, regulatory, economic or military
developments, over which the Company will have no control, will not subject the
Company to increased risk of loss of revenues and property due to, among other
things, expropriation, nationalization, inflation, currency devaluation,
international hostilities, confiscatory taxation, limitations on repatriation
and currency controls.
 
     The Company's current international sales are denominated in United States
dollars and the Company anticipates that its future international sales will be
as well. An increase in the value of the United States dollar relative to
foreign currencies could make the Company's products more expensive and
potentially less competitive in foreign markets. If for any reason exchange or
price controls or other restrictions on foreign currencies are imposed, the
Company's business, financial condition and results of operations could be
 
                                       10
<PAGE>   12
 
materially adversely affected. See "Business -- Sales, Marketing and
Distribution" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
GROWTH AND ACQUISITION RISKS
 
     The Company intends to use a substantial portion of the net proceeds from
this offering to continue to hire additional direct marketing staff, establish
strategic distribution channels and acquire additional manufacturing equipment.
It may also use a portion of the net proceeds to expand its product offerings
through acquisitions in the United States or in foreign countries. The expansion
of the marketing, distribution and manufacturing operations of the Company both
internally and through acquisitions may place substantial burdens on the
Company's management resources and financial controls. There can be no assurance
that such increased burdens would not have an adverse effect on the Company's
operating results. In addition, acquisitions may involve a number of special
risks, including adverse short-term effects on the Company's operating results,
diversion of management's attention, dependence on retention, hiring and
training of key personnel, risks associated with unanticipated problems or legal
liabilities and amortization of acquired intangible assets, some or all of which
could have a material adverse effect on the Company's operations and financial
performance. See "Use of Proceeds."
 
REQUIREMENT FOR ADDITIONAL FUNDS
 
     The Company believes that the net proceeds of this offering of
approximately $          (assuming an initial offering price of $          per
share; $          if the Underwriters' over-allotment option is exercised in
full) will be sufficient to satisfy its cash requirements for the coming
eighteen months. The Company anticipates that it may require additional funds to
cover the costs of continued research and development, manufacturing, marketing
and other operating activities. Funds for these purposes may be obtained from a
number of sources, including strategic partners, bank financing and additional
public or private sales of debt or equity. If additional funds are raised
through the issuance of equity securities, the percentage ownership of the
current stockholders of the Company will be reduced and such equity securities
may have rights, preferences or privileges senior to those of the holders of the
Company's Common Stock. However, the Company currently has no arrangements for
such financing, and there can be no assurance that any additional financing can
be obtained or, if obtained, that it will be on reasonable terms. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
     Prior to the offering there has been no public market for the Company's
Common Stock, and there can be no assurance that an active public market for the
Common Stock will develop or continue after the offering. The Company has
applied for its Common Stock to be listed on the Nasdaq National Market, but its
application is pending. If accepted for listing, adverse trends in the Company's
financial position and results of operations could result in the delisting of
its Common Stock.
 
     The trading price of the Company's Common Stock could be subject to wide
fluctuations in response to a variety of factors, many of which are beyond the
Company's control. These include (i) quarter-to-quarter variations in the
Company's operating results, (ii) announcements by the Company or its
competitors regarding new products, improvements of their technology and
regulatory approvals, (iii) developments or disputes concerning proprietary
rights, (iv) technological innovations and new products and (v) general
conditions in the medical device industry. Moreover, the stock market has
experienced extreme price and volume fluctuations, which have particularly
affected the market prices of many medical device companies and which have often
been unrelated to the operating performance of such companies.
 
RISK OF PRODUCT LIABILITY
 
     The use of the Company's products exposes it to an inherent risk of product
liability. Patients, healthcare workers or healthcare providers who claim that
the Company's products have resulted in injury could initiate product liability
litigation seeking large damage awards from the Company. Even if the litigation
is
 
                                       11
<PAGE>   13
 
successfully defended, the cost of the defense could be substantial. The Company
maintains insurance against product liability and defense costs in the amount of
$3,000,000 per occurrence and in the aggregate. There can be no assurance that
any product liability claims will be successfully defended or that the insurance
carried by the Company will be sufficient. A successful claim against the
Company in excess of insurance coverage could have a material adverse effect on
the Company. Furthermore, there can be no assurance that product liability
insurance will continue to be available to the Company on acceptable terms, if
at all.
 
PENDING LITIGATION
 
     On December 4, 1995, a complaint by plaintiffs Barry L. Rosenblatt, World
Video Movies, Ltd., whose representative is Roy K. Black, and Richard Caras,
investors in the Company's Series E Preferred Stock, against the Company,
Matthew S. Mazur and James R. Yarter, was filed in the United States District
Court for the Southern District of California, Case No. 95-3862H(RBB). The
complaint alleges the plaintiffs purchased the Company's Series E Preferred
Stock in reliance upon fraudulent misrepresentations of projections concerning
sales, revenues, profits and production capabilities of the Company. The
complaint seeks damages of $1,560,000, the amount of plaintiffs' investment in
the securities, together with interest, attorneys' fees and costs, or recision
and recovery of the $1,560,000, plus interest and attorneys' fees and costs. The
Company believes the action is without merit and is vigorously contesting the
action, which has been withdrawn once and dismissed once without prejudice.
Following its dismissal, the complaint was refiled. Plaintiffs have agreed to
immediately dismiss their claims against James R. Yarter. On August 6, 1996, the
Company filed a motion for summary judgment seeking to dispose of all of the
plaintiffs' claims.
 
     On June 28, 1996, a complaint by plaintiffs G.C. Investments LLC, whose
representative is Brian L. Greenspun (a former Director of the Company), and The
Medicine Partners, whose representative is Andrew G. Bluhm (a former Director of
the Company), investors in the Company's Series E Preferred Stock, was filed in
the United States District Court for the Southern District of California, Case
No. 96-1187H(CGA). The complaint alleges the plaintiffs purchased the Company's
Series E Preferred Stock in reliance upon fraudulent misrepresentations of
projections concerning sales, revenues, profits and the intended use of the
invested funds. The complaint seeks damages of $8,000,000, the amount of
plaintiffs' investment in the securities, together with interest, attorneys'
fees, costs and punitive damages. The Company believes the action is without
merit and is vigorously contesting the action. On August 13, 1996, the Company
filed a motion to dismiss the action for failure to state a claim.
 
     If any of the pending actions were successfully prosecuted against the
Company, the results could have a material adverse effect upon the Company's
financial position, results of operations, cash flows and ability to conduct
business. See "Business -- Legal Proceedings."
 
ISSUANCE OF PREFERRED STOCK; ANTI-TAKEOVER PROVISIONS
 
     The Board of Directors has the authority to issue up to 12,000,000 shares
of Preferred Stock, in one or more series, and to fix the number of shares and
the rights, preferences and privileges of any such series. At the time of the
closing of the offering, all of the Company's 6,693,582 shares of Preferred
Stock currently outstanding will be converted to Common Stock. Therefore, all of
the authorized Preferred Stock will be available for issuance. Accordingly, the
Board of Directors is empowered, without shareholder approval, to issue
preferred stock with dividend, liquidation, conversion, voting or other rights
which could adversely affect the voting power or other rights of the holders of
the Company's Common Stock. In the event of such issuance, the Preferred Stock
could be utilized, under certain circumstances, as a method of discouraging,
delaying or preventing a change in control of the Company. The Board of
Directors does not currently intend to issue shares of Preferred Stock.
 
     In addition, after the completion of the offering Mr. Mazur, the President
and Chief Executive Officer, will beneficially own      % of the Common Stock
outstanding (     % if the Underwriters' over-allotment option is exercised in
full). The existence of such a large block of stock could make it more difficult
for a third party to acquire a majority of the outstanding voting stock of the
Company, and may discourage or prevent a change in control of the Company.

SUBSTANTIAL SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have a total of
          shares of Common Stock outstanding (          shares if the
Underwriters' over-allotment option is exercised in full). Of these shares
          shares are "restricted securities" under Rule 144 promulgated under
the Securities Act of 1933, as amended (the "Securities Act"). Ordinarily, under
Rule 144, a person who has held restricted securities for a period of two years
may, every three months, sell in ordinary brokerage transactions or in
transactions directly with a market maker an amount equal to the greater of one
percent of the Company's then-outstanding Common Stock or the average weekly
trading volume during the four calendar weeks prior to such sale. Rule 144 also
permits the sale of shares without any quantity limitations by a person who is
not an affiliate of the Company and has satisfied a three-year holding period.
Of the           restricted shares, executive officers and directors and certain
shareholders holding an aggregate of           shares have agreed not to offer
or sell such shares for a period of 180 days after the date of this Prospectus
without the consent of the Representative on behalf of the Underwriters. Of the
remaining           restricted securities,           shares are now eligible or
will be eligible for sale under Rule 144 within 90 days from the date of this
Prospectus. Sales of Common Stock pursuant to Rule 144 may have a depressive
effect on the market price of the Common Stock.
 
     The Company has reserved 2,000,000 shares of Common Stock for issuance to
key employees, officers, directors and consultants pursuant to the Company's
stock option plans, and options for 1,377,000 of such shares are outstanding as
of the date of this Prospectus. The Company has reserved 1,820,196 shares of
Common Stock for issuance upon exercise of outstanding warrants convertible to
Common Stock. Substantially all of these options and warrants have an exercise
price that is significantly less than the offering price of the Common Stock in
this offering. The existence of such options and warrants may hinder future
equity financing by the Company. Further, the holders of such warrants and
options may exercise them at a time when the Company would otherwise be able to
obtain additional equity capital on terms more favorable to the Company. In
addition, the holders of warrants for 213,334 shares issued to certain
shareholders in connection with the private placement offering of Series E
Preferred Stock have been granted certain demand registration rights. The
existence of these registration rights may involve added costs to the Company.
See "Description of Capital Stock" and "Shares Eligible for Future Sale."
 
FORWARD-LOOKING STATEMENTS AND ASSOCIATED RISKS
 
     This Prospectus contains certain forward-looking statements which include
the plans and objectives of management for future operations, including plans
and objectives relating to the products and future financial performance of the
Company. The forward-looking statements are subject to various uncertainties and
risks set forth in this Prospectus. Those risks may include uncertainty related
to (i) the size and growth of the safety medical device industry, (ii) the
Company's ability to increase sales through the introduction and development of
new products and product lines, (iii) the success of marketing initiatives to be
undertaken by the Company, (iv) the Company's ability to forecast demand for
particular designs and products and establish production and delivery schedules
which accurately anticipate and respond to market demand and (v) the Company's
ability to achieve increases in net sales such that cost of goods sold and
selling, general and administrative expenses decrease as a percentage of net
sales.
 
     These forward-looking statements are based upon assumptions that the
Company will continue to design, develop, manufacture, market and ship new
products on a timely basis, that competitive conditions with the safety medical
device industry will not change materially or adversely, that the safety medical
device market will experience steady growth, that demand for the Company's
products will develop, that the Company will obtain customers, that the Company
will retain key personnel, that technology obsolescence risks will be minimized,
and that there will be no material adverse change in the Company's operations or
business. Assumptions relating to the foregoing involve judgments with respect
to, among other things, future economic, competitive and market conditions and
future business decisions, all of which are difficult or impossible to predict
accurately and many of which are beyond the control of the Company. Although the
Company believes that the assumptions underlying the forward-looking statements
are reasonable, any of the assumptions could prove inaccurate and, therefore,
there can be no assurance that the results contemplated in forward-looking
statements will be realized. In light of the significant uncertainties inherent
in the forward-
 
                                       13

looking statements included herein, the inclusion of such information should not
be regarded as a representation by the Company or any other person that the
objectives or plans of the Company will be achieved.
 
IMMEDIATE AND SUBSTANTIAL DILUTION
 
     This offering involves an immediate and substantial dilution to purchasers
of Common Stock offered hereby, in that the pro forma net tangible book value
per share of Common Stock after giving effect to the offering will be
$          compared to an assumed public offering price per share of $
and assuming no exercise of the Underwriters' over-allotment option, the
Representative's Warrant and any outstanding Common Stock, warrants or options.
See "Dilution."

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the           shares of
Common Stock being offered hereby at an assumed initial public offering price of
$          per share are estimated to be $          ($          if the
Underwriters' over-allotment option is exercised in full) after deducting
underwriting discounts and estimated offering expenses payable by the Company.
 
     The Company anticipates using the net proceeds of this offering as follows:
(i) approximately $6,000,000 will be used to purchase capital equipment,
including molds and automation, production and assembly machinery, (ii)
$6,000,000 will be used to fund sales and marketing activities, including an
increased direct sales force and (iii) $2,000,000 will be used to fund research
and development focused on developing additional product lines. The balance of
the net proceeds will be used for working capital and other general corporate
purposes. The Company may also use a portion of the net proceeds to acquire
technologies, products or businesses compatible with its existing business,
although the Company has no current arrangements, commitments or understanding,
in this regard.
 
     These amounts are estimates, and the amount and timing of the expenditure
of the offering proceeds will depend upon numerous factors, including the
effectiveness of the Company's sales and marketing efforts, the results of the
Company's product development efforts, and the timing of any required regulatory
approvals for future products. The Company believes that the net proceeds from
this offering, combined with cash on hand, interest expected to be earned on its
cash balances and its revenues, will be sufficient to satisfy its cash
requirements for the next eighteen months.
 
     Pending their application, the Company intends to invest the net proceeds
of this offering in bank deposits and short-term, investment grade securities,
including government obligations and money market instruments.
 
                                DIVIDEND POLICY
 
     The Company has not declared or paid any dividends since its inception and
for the foreseeable future intends to continue its policy of retaining any
earnings to finance the development and expansion of its business. In the
future, the payment of dividends by the Company on its Common Stock will depend
on the Company's financial condition, results of operations and such other
factors as the Board of Directors of the Company may consider relevant.

                                    DILUTION
 
     The pro forma net tangible book value of the Company's Common Stock at
April 30, 1996 was $          , or $          per share. The difference between
the public offering price per share of the Common Stock and the pro forma net
tangible book value per share of the Common Stock after this offering
constitutes the dilution to new investors in this offering. Pro forma net
tangible book value per share as of April 30, 1996 represents the pro forma net
tangible book value of the Company (total tangible assets less total
liabilities) divided by the shares of Common Stock after giving effect to the
conversion of all outstanding shares of Preferred Stock into Common Stock.
 
     After giving effect to the sale of           shares of the Common Stock
offered hereby at an assumed initial public offering price of $          per
share and after deducting the underwriting discounts and commissions and
estimated offering expenses, the pro forma net tangible book value of the
Company at April 30, 1996 would have been $          , or $          per share.
This represents an immediate increase in net tangible book value of $
per share to existing shareholders and an immediate dilution to new investors of
$          per share, or      %. The following table illustrates this per share
dilution:

</TABLE>
 
     If the Underwriters' over-allotment option is exercised in full, the pro
forma net tangible book value per share of Common Stock after the offering would
be $          per share, which would result in dilution to the new investors of
$          per share, or      %.
 
     The following table summarizes as of April 30, 1996 the difference between
existing shareholders and new investors with respect to the total number of

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion of the financial condition and results of
operations of the Company should be read in conjunction with the Selected
Financial Data and the financial statements of the Company and notes thereto
appearing elsewhere in this Prospectus. This Prospectus, including the following
discussion, contains forward-looking statements that involve risk and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such differences include, but are not limited to, those discussed in "Risk
Factors."
 
OVERVIEW
 
     The Company was formed in 1991 to develop medical products that protect
healthcare workers from the hazards of infection through contact with blood and
other bodily fluids. From its inception through the end of fiscal 1994, the
Company focused primarily on the design, development, and evaluation of its
first line of products, the SafeSnap syringe, and the associated design and
development of molds, assembly machines and production processes. The Company
has filed appropriate 510(k) notifications for the SafeSnap syringe with the FDA
and has received the requisite approvals.
 
     During fiscal 1995, the Company acquired and installed multicavity
injection molds for three sizes of SafeSnap syringe, molding presses, and other
production equipment, and obtained regulatory clearances for the manufacture and
sale of the SafeSnap syringe. Also during fiscal 1995, the Company began
marketing and sales efforts with regard to its initial sizes of the SafeSnap
syringe through a group of domestic medical products distributors.
 
     During fiscal 1996, the Company completed the development of the SafeSnap
syringe product line with the introduction of two additional syringe sizes and
increased its emphasis on sales and marketing.
 
     During fiscal 1997, the Company began deliveries on an initial $3,000,000
order from its Japanese distributor, strengthened its management team, continued
development of additional safety-enhanced medical products and established an
in-house direct sales force.
 
     From its inception in 1991 through January 31, 1996 and April 30, 1996, the
Company has incurred losses from operations totaling $21,977,000 and
$23,698,000, respectively. The Company currently markets its products for
clinical use in the United States, Europe and in certain foreign countries
including Japan, Australia and New Zealand. The Company anticipates increases in
product sales following the completion of this offering as a result of expanded
marketing and distribution efforts and increased manufacturing capacity.
 
RESULTS OF OPERATIONS
 
  Three Months Ended April 30, 1996 Compared to Three Months Ended April 30,
1995
 
     Net sales increased $200,000, or 909%, to $222,000 for the three months
ended April 30, 1996 from $22,000 for the three months ended April 30, 1995.
This increase is primarily attributable to shipments to the Company's
distributor in Japan pursuant to an initial $3,000,000 purchase order from this
distributor.
 
     Pre-manufacturing and manufacturing costs decreased $418,000, or 31%, to
$937,000 for the three months ended April 30, 1996 from $1,355,000 for the three
months ended April 30, 1995. The reduction is primarily a result of lower
overhead costs during fiscal year 1996 due to the Company's re-engineering of
certain manufacturing processes. In addition, certain non-recurring
pre-manufacturing costs were incurred during fiscal year 1995 due to the
construction of machinery for new syringe sizes as the Company completed its
SafeSnap syringe product line.
 
     General and administrative expenses increased $104,000, or 26%, to $502,000
for the three months ended April 30, 1996 compared to $398,000 for the three
months ended April 30, 1995. This increase was due primarily to costs associated
with the addition of management personnel and increased legal costs.
 
                                       19
<PAGE>   21
 
     Selling and marketing expenses increased $156,000, or 79%, to $354,000 for
the three months ended April 30, 1996 from $198,000 during the three months
ended April 30, 1995. The increase is due primarily to the Company's hiring of a
direct sales force and three experienced area sales directors.
 
     Research and development expenses decreased $61,000, or 34%, to $117,000
for the three months ended April 30, 1996 from $178,000 for the three months
ended April 30, 1995 as the Company's 1cc and 10cc size SafeSnap syringes moved
out of the development stage and into production. Continued research and
development is focused primarily on the Company's new safety products currently
under development.
 
     Interest expense and debt issuance costs decreased $7,000, or 18%, to
$33,000 for the three months ended April 30, 1996 from $40,000 for the three
months ended April 30, 1995.
 
  Year Ended January 31, 1996 Compared to Year Ended January 31, 1995
 
     Net sales increased $328,000, or 745%, to $372,000 for the year ended
January 31, 1996 from $44,000 for the year ended January 31, 1995. This increase
is attributable to the introduction of the 1cc and 10cc size SafeSnap syringes,
which provided customers the ability to purchase a comprehensive line of
syringes. The Company's sales were primarily made to its Japanese distributor.
 
     Pre-manufacturing and manufacturing costs increased $1,040,000, or 26%, to
$4,966,000 for the year ended January 31, 1996 compared to $3,926,000 for the
year ended January 31, 1995, due to the hiring of additional manufacturing
employees necessary to meet the increased production demands and increased
depreciation on machinery and equipment purchased to meet the expected demand
for the Company's products.
 
     General and administrative expenses increased $708,000, or 58%, to
$1,925,000 for the year ended January 31, 1996 compared to $1,217,000 for the
year ended January 31, 1995. This increase was due to accounting and legal costs
associated with consideration of various financing arrangements, additions to
the senior management team, an increase in property taxes due to new machinery
and equipment purchases and legal fees incurred in connection with a debt
restructuring and a legal action brought against the Company.
 
     Selling and marketing expenses decreased $195,000, or 17%, to $941,000 for
the year ended January 31, 1996 from $1,136,000 for the year ended January 31,
1995. During fiscal 1995, the Company ran an advertising campaign to promote
sales of the SafeSnap syringe through smaller independent distributors. This
program was discontinued in early fiscal 1996, as the Company focused its
efforts on building a direct sales force and strategic distribution alliances.
 
     Research and development expenses decreased $269,000, or 31%, to $588,000
for the year ended January 31, 1996 from $857,000 for the year ended January 31,
1995. The decrease was due to reduced research and development expenses during
fiscal 1996 as compared to fiscal 1995, as many of the Company's syringes,
including the 1cc and 10cc sizes, moved out of the development stage and into
production.
 
     Interest expense and debt issuance costs increased $560,000, or 273%, to
$765,000 for the year ended January 31, 1996 from $205,000 for the year ended
January 31, 1995 due to interest costs of a promissory note previously given by
the Company, amortization of debt issuance costs, and costs associated with the
conversion of the note to equity.
 
     Other expenses for the year ended January 31, 1995 were $185,000 primarily
related to a loss on extinguishment of shareholder debt whereby the Company
issued Series D Preferred Stock and Common Stock warrants and paid cash to
settle a promissory note including accrued interest. No similar expenses were
incurred in fiscal 1996.
 
  Year Ended January 31, 1995 Compared to Year Ended January 31, 1994
 
     Net sales were $44,000 for the year ended January 31, 1995 compared to
$1,000 for the year ended January 31, 1994. The Company's focus during this
period was primarily on relocation and capital improvements and the regulatory
approval process.
 
                                       20
<PAGE>   22
 
     Pre-manufacturing and manufacturing costs increased $3,300,000, or 527%, to
$3,926,000 for the year ended January 31,1995 compared to $626,000 for the year
ended January 31, 1994. The increase was primarily due to costs necessary to
prepare the Company's facility for full production. These costs included
production set up and the establishment of new production departments and their
associated employees.
 
     General and administrative expenses increased $168,000, or 16%, to
$1,217,000 for the year ended January 31, 1995 compared to $1,049,000 for the
year ended January 31, 1994. The increase resulted from the addition of finance
and administrative personnel to assist in the Company's growth and increased
rent expense associated with the Company's new facility.
 
     Selling and marketing expenses increased $751,000, or 195%, to $1,136,000
for the year ended January 31, 1995 compared to $385,000 for the year ended
January 31, 1994. The increase was due to increased costs related to an
extensive advertising campaign to promote sales of the SafeSnap syringe through
distributors and an increase in sales and marketing personnel in order to
support market introduction of the SafeSnap.
 
     Research and development expenses decreased $259,000, or 23%, to $857,000
for the year ended January 31, 1995 as compared to $1,116,000 for the year ended
January 31, 1994. This reduction was due to the Company moving out of the
development phase and into the production phase with regard to certain sizes of
its SafeSnap syringe. Also, patent expenses were incurred during fiscal year
1994 that were not incurred during fiscal year 1995.
 
     Interest expense and debt issuance costs for the year ended January 31,
1995 increased to $205,000 from $67,000 for the year ended January 31, 1994 due
to an increase in long-term debt to finance the Company's continued operations.
 
     Other expenses for the year ended January 31, 1995 were $185,000 primarily
related to a loss on extinguishment of shareholder debt whereby the Company
issued Series D Preferred Stock and Common Stock warrants and paid cash to
settle a promissory note including accrued interest. No similar expenses were
incurred during fiscal 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In August 1996, the Company entered into an agreement with Merrill Lynch
Business Financial Services, Inc. ("Merrill Lynch") whereby Merrill Lynch has
agreed to provide the Company a $2.3 million working capital line of credit, at
a variable interest rate based on 2.65% plus the 30-day Commercial Paper Rate
(as published in the Wall Street Journal). As of July 31, 1996, the interest
rate was 8.07%. The loan is subject to an annual fee and is secured with a
security interest in assets pledged by a shareholder of the Company.
 
     Historically, the Company has relied upon equity funding and limited
borrowing from management and certain shareholders to fund operations. There are
no commitments for such financings with any of these individuals and no
assurance can be given that such borrowings will continue to provide a source of
funds.
 
     The Company's need for funds has increased from period to period as it has
increased the research and development of the SafeSnap product line and its
related production processes, increased its capital expenditures on molds and
production equipment, expanded staff, and commenced production of its SafeSnap
syringe line. The cumulative net loss incurred by the Company through April 30,
1996 was $23,698,000. The Company had negative working capital of $1,089,000 at
April 30, 1996. As of April 30, 1996, the Company had raised capital of
$31,771,000.
 
     The report of the Company's independent accountants with respect to the
Company's financial statements for the three years ended January 31, 1996
contains an explanatory paragraph which states that "the Company is in the
development stage, has incurred a cumulative net loss since inception and is
dependent on additional financing in order to continue its operations and
execute its growth strategy. These factors, among others, raise substantial
doubt about the Company's ability to continue as a going concern." The financial
statements included herein have been prepared assuming the Company will continue
as a going concern and do not include any adjustments that might result from the
outcome of this uncertainty. The
 
                                       21
<PAGE>   23
 
Company has been advised by its independent accountants that, upon completion of
this offering, the independent accountants expect to issue a report without the
explanatory paragraph as described above. Notwithstanding the foregoing, there
can be no assurance that such conditions will not recur or that the accountants'
report will not contain such an explanatory paragraph in the future.
 
     The Company also anticipates that sales of its SafeSnap syringes will
satisfy an increasing percentage of its capital requirements. However, the
Company's gross margin is affected by a number of factors, including product
mix, product pricing, the extent of sterile, packaged safety syringe sales
versus bulk, non-sterile safety syringe sales, and the percentage of direct
sales compared to distributor sales and manufacturing costs, including overhead
and material costs. Any decline in the average selling price of a particular
product not offset by a reduction in production costs or by sales of other
products with higher gross margins would decrease the Company's overall gross
margin and adversely affect the Company's liquidity and capital resources.
 
     Although the Company believes that the net proceeds of this offering will
support the Company's operations and planned capital expenditures for
approximately eighteen months after the closing of this offering, the Company's
future liquidity and capital requirements will depend on numerous factors,
including market demand for its products, the expansion of the sales and
marketing force, regulatory actions by the FDA and other regulatory bodies and
intellectual property protection. The Company's need for capital could vary
based on the actual rate of sales growth and the level of additional investment
required to further increase manufacturing capacity. Failure to raise needed
capital would have a material adverse effect on the Company's operations,
development plans and cash flows. In such case, the Company would attempt to
reduce costs and expenses, in turn slowing the Company's planned rate of
expansion.
 
NET OPERATING TAX LOSS CARRYFORWARDS
 
     The Company has incurred net losses since inception and therefore has not
been subject to state or federal income taxes. At January 31, 1996, the Company
had federal and California net operating tax loss carryforwards ("NOL") of
approximately $17,000,000 and $8,500,000, respectively, available to reduce
future income taxes. The difference between the federal and California NOL is
primarily attributable to the 50% limitation on California loss carryforwards.
The federal and California NOL begin expiring in 2008 and 1998, respectively,
unless used. The Company also has research and development credit carryforwards
for federal and state tax reporting purposes totaling approximately $166,000 and
$87,000, respectively, which expire at various times through 2009. Pursuant to
the Internal Revenue Code, use of the Company's NOL and credit carryforwards may
be limited because of a change in ownership of more than 50%, which management
believes occurred in the year ended January 31, 1995. As a result, the Company
believes that its ability to utilize its current net operating loss and credit
carryforwards, and to realize the benefit of future tax deductions in subsequent
periods will be subject to annual limitations of approximately $1,600,000 for
net operating losses generated through the year ended January 31, 1995. The
Company also believes that a second change in ownership may occur at the closing
of this offering. The Company does not believe these limitations will have a
material impact upon its utilization of the NOL and credits over their
respective carryforward periods; however, the Company does believe they will
impact the timing of such utilization.

                                    BUSINESS
 
GENERAL
 
     The Company designs, develops, manufactures and markets proprietary,
safety-enhanced, disposable medical products intended to protect healthcare
workers from the spread of infectious diseases such as AIDS and hepatitis. The
Company's first product line, the SafeSnap syringe, consists of a line of
single-use hypodermic syringes designed to reduce the risk of transmission of
blood borne diseases from accidental needlesticks. A SafeSnap syringe is similar
in appearance, size and manner of use to a standard (i.e., non-safety) syringe;
however, it incorporates patented retraction and encapsulation technology that
isolates the needle within the barrel of the syringe immediately after use,
facilitating safe disposal. The Company's SafeSnap product line consists of four
syringes which vary by size, needle length and gauge. The SafeSnap syringe is
also latex-free and will not cause adverse reactions in the estimated 8-10% of
patients and healthcare workers with allergies to latex. The Company believes
that the SafeSnap syringe is the only safety syringe currently on the market
that is latex-free. The Company has five additional safety product lines under
development: a winged butterfly set, an arterial-venous fistula set, a blood gas
syringe, a needleless vial adaptor and a phlebotomy (blood collection) device.
 
INDUSTRY TRENDS
 
  Accidental Needlesticks
 
     Infections contracted as a result of accidental needlesticks from syringes
and other instruments used to inject medication or collect body fluids are of
significant concern to healthcare institutions, healthcare workers and the
various agencies charged with regulating their work environments. Accidental
needlesticks are the second leading cause of hospital injury, accounting for
more than one-third of all hospital injuries. Industry reports estimate that
over 800,000 accidental needlesticks occur within the United States each year.
The estimated cost of each reported accidental needlestick is up to
approximately $1,200 for treatment of the wound, diagnostic tests and lost
worker time. This figure does not include specialized, longer term treatment and
potential liability costs.
 
     Hepatitis and HIV are transmitted through blood and other body fluids, and
workers who come in contact with such fluids are at risk of contracting these
and other diseases. Transmission may occur from needlesticks by contaminated
needles or exposure of mucous membranes to body fluids containing blood traces.
The Centers for Disease Control ("CDC") estimates that approximately 12,000
hepatitis infections occur each year in healthcare workers with occupational
exposure to blood and other potentially infected body fluids, resulting in more
than 6,000 cases of symptomatic hepatitis, approximately 600 hospitalizations
and more than 200 deaths. The Occupational Safety and Health Administration
("OSHA") estimates that the incidence of hepatitis infection in healthcare
workers with exposure to blood and other potentially infected body fluids is
more than twice as great as the incidence of infection in the general
population. OSHA has determined that the increased incidence of HIV infection
among healthcare workers with no known risk factors is statistically
significant. The United States Public Health Service estimates that there are
approximately one million cases of HIV infection in the United States. In
addition to the HIV and hepatitis viruses, there are a number of other blood
borne diseases which can be transmitted by accidental needlesticks and which
also have serious consequences for the victim, including diphtheria, gonorrhea,
typhus, herpes, malaria, rocky mountain spotted fever, syphilis and
tuberculosis.
 
     The possibility of infection to healthcare workers from contaminated
needles has caused and continues to cause a great deal of concern in the
healthcare field and its regulatory agencies. OSHA has adopted regulations
requiring employers to institute "universal precautions" to prevent contact with
blood and other body fluids. OSHA's regulations also require employers to
establish controls (such as sharps disposal containers and self-sheathing
needles) and safe work practices to ensure compliance with these universal
precautions. OSHA does not mandate specific technologies; rather, employers are
permitted to choose the most appropriate and effective safety control devices to
meet their specific institutional needs. According to OSHA guidelines, while
employers are not required to institute the most sophisticated controls, they
must evaluate the effectiveness of their existing controls and evaluate the
feasibility of instituting more advanced
 
                                       23
<PAGE>   25
 
controls. OSHA specifically prohibits the recapping, bending or removal of
needles, unless there is no feasible alternative or unless required for a
specific medical procedure.
 
     The FDA has issued a safety alert to hospitals warning of the risks of
needlestick injuries from the use of hypodermic needles with intravenous
equipment. Among other things, the safety alert stated that, although the FDA
could not recommend specific products, it urged the recipients of the alert to
use needleless systems or recessed needle system devices with a fixed safety
feature. According to the alert, (i) a fixed safety feature should provide a
barrier between the hands and needle after use, (ii) the safety feature should
allow or require the worker's hand to remain behind the needle at all times,
(iii) the safety feature should be an integral part of the device and not an
accessory, (iv) the safety feature should be in effect before disassembly and
remain in effect after disposal to protect both users and disposers of medical
devices and for environmental safety, and (v) the safety feature should be as
simple as possible and require little or no training for effective use.
 
     In addition, the CDC and the National Institutes of Health have published
guidelines that specify that needles should not be re-sheathed, bent, broken,
removed from disposable syringes or otherwise manipulated by hand because of the
potential for needlestick injury and the associated risk of blood-related
infection.
 
  Market for Syringes, Safety Syringes and other Safety Medical Products
 
     Currently, more than an estimated 15.5 billion disposable syringes are sold
each year worldwide. The U.S. market accounted for an estimated 5.2 billion
units in 1995. Safety syringes are estimated to represent a small portion of
total current U.S. syringe sales, but sales are expected to grow at a faster
rate than the domestic syringe market as a whole as better designs and lower
prices become available. Industry reports project that demand for safety
syringes will increase each year through 2001 as healthcare providers convert to
safety syringes. Thereafter, increases in demand are expected to reflect changes
in patient populations and in injectable treatment therapies, including an
increase in the number of elderly Americans, growing use of multiple-injection
insulin regimens for diabetics, and the growing availability of biotechnology
drugs, which typically require parenteral administration.
 
     Nearly 400 million arterial, central venous, intravenous, and urological
catheters were sold in the U.S. in 1993, representing approximately a $100
million domestic market. The Company believes that at least half of these 400
million catheters are winged butterfly sets.
 
     Arterial-venous fistula needles are estimated to represent 20 percent of
total disposable specialty needle and syringe revenues. The number of units sold
in 1995 are estimated to be 44 million domestically. Domestic sales for 1996 are
estimated in industry reports to be $18 million with annual projected growth of
5%. The Company believes this market is being driven by an increase in the
end-stage renal dialysis patient population and shortages in the number of
transplant organs which have increased the demand for dialysis. Arterial-venous
fistula needles are used in hospitals, but use is growing at faster rates in
hemodialysis clinics and centers.
 
     Blood gas syringes, including intra-arterial catheters and intra-arterial
blood gas analyzers, are new products in the blood collection segment. Revenue
data for the disposable blood gas kit market provides limited indications of the
growth potential for blood gas syringes. Revenues for the blood gas kit market
were approximately $42 million (70 million units) in 1992 and are estimated to
reach $58 million in 1999.
 
     According to industry reports, phlebotomy devices represent a $250 million
industry domestically that is growing at a rate of 30% annually. Safety
phlebotomy devices are a relatively new segment of this market and are estimated
to account for approximately 25% of the current blood collection market with a
projected growth rate of 15%. Safety phlebotomy devices are projected to
represent more than 65% of the blood collection market by 1998.

PRODUCTS
 
  SafeSnap
 
     SafeSnap is a patented line of single-use hypodermic syringes that are
intended to reduce the incidence of accidental needlesticks. SafeSnap syringes
are presently available in the 1cc, 3cc, 5cc and 10cc sizes. These sizes account
for approximately 90% of the hypodermic syringe market. The  1/2cc SafeSnap
syringe is in the pilot manufacturing stage, and will expand the Company's line
of syringes that are most commonly used for patient injections.
 
     The SafeSnap syringe is similar in appearance, size, and manner of use to
standard syringes. However, the SafeSnap design has several unique features. The
SafeSnap design permits the used needle to retract into the barrel of the
syringe, shielding the needle from accidental human contact. The plunger rod is
designed to be broken off once the needle is fully retracted, thereby preventing
re-use. Once broken off, the plunger rod is inserted into the front end of the
barrel, completely enclosing the needle within the barrel. In effect, the
syringe is transformed into a sealed container for the contaminated needle. The
SafeSnap design also employs a unique needle carrier, which is a separate piece
within the barrel, with a clear silicone o-ring, and a locking mechanism.
Whereas in an ordinary syringe the needles attaches to the barrel, the needle in
the SafeSnap attaches to the needle carrier. The locking feature on the needle
carrier allows the users to use their needle-of-choice with the SafeSnap
syringe. The SafeSnap syringe is sold with or without a needle and may be used
with several needle sizes. The product is packaged using color-coded
identification that is comparable to other standard hypodermic syringes.
 
     The methods of use and disposal of SafeSnap syringes are virtually
identical to those for standard syringes. The Company's SafeSnap syringes sell
for approximately the same price as other safety syringes, but the Company's
SafeSnap design is unique among safety syringes. All other currently available
safety syringes use an external sheath design which generally requires the
operator to move a protective sheath over the needle after the needle has been
removed from the patient (a sliding sleeve) or manipulate the device to cover
the used needle tip (a disappearing needle). The outer protective sheath of a
sliding sleeve design can obscure calibration markings on the side of the
syringe when it is retracted. Moreover, the SafeSnap's retractable design uses
approximately 40% less space in a "sharps" container than either the sliding
sleeve or the disappearing needle design, thereby reducing disposal costs.
 
     The Company believes that the SafeSnap syringe is the only safety syringe
currently on the market that is latex-free. There is a growing concern among
healthcare workers and patients about allergic reactions to products containing
latex. Studies indicate that 8-10% of healthcare workers have allergic reactions
to latex, ranging in severity from hives to the potentially fatal asthma-like
condition known as anaphylactic shock. The FDA has recently proposed a labeling
system for latex products that would warn of possible allergic reactions. It is
the Company's intent that all of its new products will also be latex-free, if
the products can be so manufactured.
 
  Products Under Development
 
     The Company is planning to enter additional markets for complementary
products where it believes its technology, manufacturing capability and market
presence can assist it in gaining significant market share. The Company is
developing designs for the devices indicated below and has produced prototypes
of two of these products, the winged butterfly set and the needleless vial
adapter. There can be no assurance that the Company will successfully design,
manufacture or sell any such products.
 
     Winged Butterfly Set.  Winged butterfly sets are used most frequently with
children to provide multiple doses of medication without unnecessary pain to the
patient. Another popular application is drawing blood from patients, when
syringes or vacuum tube systems are impractical. The device consists of a small
housing with a needle at the end, which is taped to the skin by two plastic
wings attached to the housing. In order to preserve its international patent
rights, the Company will file a U.S. patent application covering the unique
inventions embodied in the Company's device prior to making any public
disclosure of them.
 
                                       25
<PAGE>   27
 
     Needleless Vial Adapter.  The current practice of filling a syringe with
medication to administer an injection requires attaching a needle to a syringe,
uncapping the needle, and inserting the needle into the medication vial. The
plunger is then drawn back, pulling medication through the vacuum seal into the
vial. The needle with syringe is then removed from the vial, and an injection is
given to the patient with the syringe. This process is oftentimes cumbersome to
accomplish. More importantly, this process is often performed in a room separate
from the injection site, resulting in the need to either recap the needle and/or
expose the previously sterile needle to pathogens during travel to the injection
site. In order to preserve its international patent rights, the Company will
file a U.S. patent application covering the unique inventions embodied in the
Company's device prior to making any public disclosure of them.
 
     Arterial-Venous Fistula Set.  An arterial-venous fistula set consist of a
winged needle connected to plastic tubing. A fistula needle is inserted into the
arterialized vein of a patient undergoing hemodialysis treatment. The Company
anticipates that a private label packaging agreement under negotiation with its
needle supplier will provide the Company with a standard arterial-venous fistula
device to market and sell. If negotiations are successful, prior to marketing
the arterial-venous fistula set, the Company will need to secure 510(k)
premarket clearance for the device. In order to preserve its international
patent rights, the Company will file a U.S. patent application covering the
unique inventions embodied in the Company's device prior to making any public
disclosure of them.
 
     Blood Gas Syringe.  Blood gas sampling currently involves drawing a blood
sample into a blood gas syringe via an arterial catheter and then analyzing the
sample with a blood gas analyzer. In order to preserve its international patent
rights, the Company will file a U.S. patent application covering the unique
inventions embodied in the Company's device prior to making any public
disclosure of them.
 
     Phlebotomy Device.  Phlebotomy devices collect and store blood during
transport. Blood drawing is a very common practice in the healthcare industry
and is often performed by medical assistants or healthcare workers whose levels
of training and education are not as extensive as that of nurses. The Company
believes that the risk of accidental needlesticks arising from the use of such
devices may be even greater than from the use of syringes. In order to preserve
its international patent rights, the Company will file a U.S. patent application
covering the unique inventions embodied in the Company's device prior to making
any public disclosure of them.
 
STRATEGY
 
     The Company's objective is to use its proprietary technology to establish
itself as a leading provider of safety syringes and other safety related medical
devices. To achieve this objective, the Company's growth strategy is focused on
the following three principal elements:
 
     Increasing its customer base through direct selling efforts and
establishing strategic distribution channels. The Company has recently begun the
hiring of its planned 24 member direct sales force, a majority of which have
been hired, which will establish a presence in 24 major metropolitan areas in
the United States. Since January 1996, the Company has also added a new Vice
President of Sales and area sales directors. As demand increases, the Company
plans to augment its sales force with additional personnel.
 
     In April 1995, the Company received a $3 million order from its Japanese
distributor, a leading manufacturer and marketer of healthcare products in Asia.
In December 1995, the Company received premarket approval for the SafeSnap
syringe from the Ministry of Health in Japan. The Company began shipping to its
Japanese distributor in early calendar 1996 and expects to fill this order by
the end of the fourth quarter of calendar 1996. The distributor purchases the
Company's products and markets them through its 300 person direct sales force.
The distributor is actively promoting and supporting the Company's SafeSnap
products through various marketing programs. The Company believes that over time
the relationship with its Japanese distributor may lead to a substantial
increase in sales and the penetration of additional Asian markets.
 
     Broadening its product lines by applying its technology, manufacturing
capabilities and market presence developed with the SafeSnap syringe.  The
Company has invested approximately $9,600,000 in machinery
 
                                       26
<PAGE>   28
 
and equipment since its inception for the production of its SafeSnap syringe
line. That same machinery will be used to assist in the development and
production of the five new products under development, as well as other future
products. The Company also intends to continue its research and development to
exploit its proprietary expertise to develop additional products in addition to
the future products discussed elsewhere in this Prospectus.
 
     The Company intends to minimize the cost and time necessary to bring its
new products to market by using the information and experience gained in the
design, development and assembly of its safety syringe line since such new
products employ a safety feature to reduce the accidental transmission of blood
or other body fluids to a healthcare worker during or after use. The Company
also plans to use the sales and distribution channels it has developed for its
safety syringes to support these follow-on products. The Company plans to
continue development of each of these devices but has not built the production
equipment necessary to assemble these devices, nor has it conducted tests or
produced a commercial version of any of these devices.
 
     Reducing per unit cost by increasing unit volume, completing the Company's
automation of assembly and printing processes and incorporating design
enhancements in production tooling.  The Company relocated its manufacturing
operations to a modern 55,000 square foot facility in San Diego, California in
April 1994. This facility is expected to accommodate the Company's needs for at
least the next two years. The Company will use a portion of the net proceeds
from the offering to acquire additional equipment and facilities for the
manufacturing of a full line of SafeSnap syringes and, to the extent possible,
for the manufacture of its products under development.
 
     To achieve profitability the Company must reduce its per-unit manufacturing
costs which currently exceed the Company's average selling price in the SafeSnap
syringe line. The Company expects to achieve significant reduction in per-unit
manufacturing costs as production volume increases and as a result of cost
saving efforts. These other cost-saving efforts include the completion of the
Company's automated assembly and printing processes through the acquisition of
additional molds and equipment, ongoing improvements in overall manufacturing
processes and reducing scrap, as well as planned reductions in component costs
through design enhancements in production tooling and other efforts in
cooperation with its outside suppliers. The Company believes that the proceeds
of this offering will enable it to achieve per-unit cost reductions during the
balance of fiscal 1997 and fulfill its plans to further reduce per-unit costs in
fiscal 1998 and 1999.
 
RESEARCH AND DEVELOPMENT
 
     The Company has devoted a substantial portion of its efforts since its
formation to research and development concerning safety medical products and the
design and production of the SafeSnap syringe product line. As of April 30,
1996, research and development costs since the inception of the Company totaled
$3.4 million. The Company remains committed to continued funding of research
focused on product development and improvement.
 
     The Company believes it has substantially completed its research and
development of the SafeSnap syringe line. While there may be changes to the
manufacturing process, the Company does not anticipate any significant changes
to the syringe. With a portion of the net proceeds of this offering, the Company
plans to continue research and development of all of its future products and the
equipment of manufacturing processes needed for such products. In that process,
the Company expects to draw heavily upon its experience with the retractable
syringe and other safety features contained in the SafeSnap syringe.
 
COMPETITION
 
     The syringe market is highly competitive. Becton, Dickinson and Company
("B-D") and Sherwood Medical ("Sherwood"), an American Home Products Corporation
subsidiary, are the two major domestic competitors which garner approximately
70% and 20%, respectively of revenues in the U.S. syringe market. B-D and
Sherwood, as well as numerous other smaller companies, also manufacture safety
syringes that use plastic sleeves or shields as protective devices. Terumo
Medical Corporation of Japan is a major international competitor in the standard
syringe market. The Company believes that the SafeSnap syringe is superior in
its design, quality and convenience of use to all other safety syringes on the
market today. However, many of the
 
                                       27
<PAGE>   29
 
Company's competitors have longer operating histories and are substantially
larger, better financed and better situated in the market than the Company. Some
of these larger competitors have the potential marketing advantage of being able
to offer multiple products to the Company's current or prospective customers.
 
     The Company's initial product, SafeSnap, competes with both standard and
safety syringes. The Company believes that its safety syringes are a
cost-effective alternative to standard syringes. Safety syringes, including
SafeSnap syringes, sell at approximately two to three times the price of
standard syringes depending on the market segment. Historically, the syringe
market has been price competitive with little differentiation between products.
In recent years, however, due to the high cost of treating infections, and the
potential for liability, the medical industry has adopted infection control
practices which encourage the use of safer medical devices. The Company believes
that for the average hospital, the incremental cost of using safety syringes
should be less than the direct costs resulting from accidental needlesticks
which would otherwise occur.
 
     The Company believes it will also face significant competition in its
product lines that are under development from established and well financed
entities. Competitors in the catheter market include Abbott Labs, Sherwood, B-D
and Johnson and Johnson Medical, Inc. Competitors in the arterial-venous fistula
market include Medisystems Corporation, National Medical Care, and Terumo
Medical Corporation, which collectively control 81% of the market. Two companies
are currently developing safety mechanisms for fistula needles: Medisystems
Corporation, which markets the Pointguard safety device, and MBO Laboratories/
Sherwood, which markets the Angel-Wing safety device for venous infusion.
Competitors in the blood gas market include anesthesia product manufacturers,
blood gas analyzer manufacturers, and general healthcare manufacturers.
Disposable blood gas kit manufacturers include Concord/Portex, B-D and
Radiometer America.
 
SALES, MARKETING AND DISTRIBUTION
 
  Domestic
 
     The Company has developed a multi-segmented approach to the domestic
distribution and sale of its products. The market segments for safety medical
products can be broadly segregated into acute care (hospitals), alternate sites
(clinics, hospices, ambulatory care), and retail (physicians offices and home
care). The Company has assessed the sales cycle for each segment, the size of
the segment, the number of facilities per segment, the cost to enter each
segment, the competition within each segment, and the barriers to entry such as
group purchasing organizations ("GPO") for acute care. The Company has further
divided the domestic market into regional territories and identified those
facilities that are on GPO contracts, government entities, stand-alone
facilities, and high-volume accounts. The Company has developed approaches to
penetrate each of these market segments through a combination of a direct
selling force, strategic alliances, and telemarketing.
 
     The Company has expanded its selling force, managed by area sales
directors, to penetrate the acute care market which has the longest sales lead
time, highest volume per facility and is the most price sensitive. The direct
sales force has recently been placed in the field resulting in several product
evaluations and multiple new accounts. The purpose of this direct selling force
is to create the initial product demand necessary to enter into significant
distribution and group purchasing agreements for the Company's current and
future products.
 
     The Company's direct sales force is focused on gaining market acceptance of
the SafeSnap syringe in the U.S. hospital and large alternate care market.
Between July 1995 and July 1996, the Company increased its hospital account base
for this product from two customers to 15 customers. In addition, the Company
increased its product trials from approximately 12 to approximately 60 during
the same period. The Company believes that, as it establishes distribution
channels for its initial SafeSnap product, these channels will also be available
to its products under development. However, the introduction of new technologies
to hospitals and large clinics can be a lengthy process and typically involves
screening by many individuals and committees within each institution. Committees
include, for example, new product evaluation committees, product trials,
infection control, safety, risk management, and purchasing.
 
                                       28
<PAGE>   30
 
     The sales force is primarily focused on the acute care market, which
includes regional GPO accounts, but will also pursue larger account leads from
the alternate care segment. The Company intends to increase the size of its
direct selling force as the Company moves through its growth stage and
introduces new products.
 
     The telemarketing department focuses primarily on the alternate care
market, in particular those smaller alternate care facilities which do not
generally receive sales calls by a distributor or sales person. For the larger
alternate care facilities or alternate site buying groups, the telemarketing
department focuses on lead qualification for follow-up by the direct selling
force to allow a more focused direct selling approach.
 
     Strategic distribution arrangements in the domestic market may include
distribution agreements with GPO organizations, pre-packaging of the Company's
products with kit manufacturers, and private labeling. The Company will attempt
to focus on those alliances which complement its current sales and marketing
approach and that do not overlap with current market strategies.
 
  International
 
     The Company's international sales strategy is to establish strategic
distribution channels or relationships with companies with established
distribution channels in their respective markets. These companies will be
familiar with the key success variables within the markets they serve including
related laws and regulations. Certain foreign countries may only require the
Company to submit evidence of the FDA's premarket clearance of the Company's
products prior to sale, however, some foreign countries may have more stringent
requirements and require additional testing and approvals.
 
     The Company has received an initial $3,000,000 order from a Japanese
distributor. The distributor has a direct sales force of approximately 300
representatives in Japan and handles all account servicing, conversions and
in-country distribution.
 
MANUFACTURING
 
     Manufacturing of the Company's products involves precision injection
molding of plastic parts, manual and automated assembly of molded plastic parts,
needles and other components, quality control inspection, packaging, and
sterilization. The Company currently occupies a 55,000 square foot facility in
San Diego, California, which includes a Class 100,000 (less than 100,000
particles per cubic foot) controlled environment room for its injection molding
machines, as well as printing equipment, assembly machines and packaging
equipment. The facility is vertically integrated with design, mold making,
molding, printing, assembly, and packaging all in the same location. As of April
30, 1996, the Company had invested $9,600,000 in molds, injection molding
machines, assembly equipment, and packaging equipment. The Company produces
molded parts for its entire SafeSnap syringe product line. The Company has
established a high-speed, fully automated production line for the molding,
printing, assembly and packaging of the 3cc size SafeSnap syringe. The Company
also molds, prints and packages the remaining sizes at its facility. Assembly of
those sizes is currently performed by third-party subcontractors. The Company
will use a portion of the proceeds of this offering to implement automation of
the printing and assembly processes for those remaining syringe sizes.
 
     The Company designs and builds most of its high precision molds and
prototypes. The Company's computer-assisted design systems, automated machining
equipment and internal prototype mold-making capacity have enabled the Company
to reduce the lead time for prototype tooling for new products.
 
     Management believes that the continued investment of capital in high-speed
automation equipment should enhance the prospects of reducing manufacturing
costs and increasing margins. The Company's production plan is to continue its
joint manufacturing agreements with its subcontractors to assemble and package
the SafeSnap syringe while designing and acquiring additional high-speed
automated production equipment. Fully-integrated high-speed production should
permit the Company to recognize significantly better per unit costs due to
efficiencies and economies of scale and the reduction in direct labor expense.
 
                                       29

GOVERNMENT REGULATION
 
     The testing, manufacture and sale of the Company's products are subject to
regulation by numerous governmental authorities, principally the FDA and
corresponding state and foreign regulatory agencies. Pursuant to the Federal
Food, Drug and Cosmetic Act (the "FDC Act"), and the regulations promulgated
thereunder, the FDA regulates the preclinical and clinical testing, manufacture,
labeling, distribution and promotion of medical devices. Noncompliance with
applicable requirements can result in, among other things, fines, injunctions,
civil penalties, recall or seizure of products, total or partial suspension of
production, failure of the government to grant premarket clearance or premarket
approval for devices, withdrawal of marketing clearances or approvals, and
criminal prosecution. The FDA also has the authority to request recall, repair,
replacement or refund of the cost of any device manufactured or distributed by
the Company.
 
     In the United States, medical devices are classified into one of three
classes (i.e., Class I, II or III) on the basis of the controls deemed necessary
by the FDA to reasonably ensure their safety and effectiveness. Class I devices
are subject to general controls (such as labeling, premarket notification and
adherence to Good Manufacturing Practices ("GMP") and Class II devices are
subject to general and special controls (such as performance standards,
postmarket surveillance, patient registries, and FDA guidelines). Generally,
Class III devices are those which must receive premarket approval by the FDA to
ensure their safety and effectiveness (such as life-sustaining, life-supporting
and implantable devices, or new devices which have been found not to be
substantially equivalent to legally marketed devices).
 
     Before a new device can be introduced in the market, the manufacturer must
generally obtain FDA clearance or approval through either clearance of a 510(k)
notification or approval of a PMA. A PMA application must be filed if a proposed
device is not substantially equivalent to a legally marketed Class I or Class II
device, or if it is a Class III device for which the FDA has called for PMAs. A
PMA application must be supported by valid scientific evidence to demonstrate
the safety and effectiveness of the device, typically including the results of
clinical trials, bench tests, laboratory and animal studies. The PMA must also
contain a complete description of the device and its components, and a detailed
description of the methods, facilities and controls used to manufacture the
device. In addition, the submission must include the proposed labeling,
advertising literature and any training materials. The PMA process can be
expensive, uncertain and lengthy, and a number of devices for which FDA approval
has been sought by other companies have never been approved for marketing.
 
     Upon receipt of a PMA application, the FDA makes a threshold determination
as to whether the application is sufficiently complete to permit a substantive
review. If the FDA determines that the PMA application is sufficiently complete
to permit a substantive review, the FDA will accept the application for filing.
Once the submission is accepted for filing, the FDA begins an in-depth review of
the PMA. The FDA review of a PMA application generally takes one to three years
from the date the PMA is accepted for filing, but may take significantly longer.
Toward the end of the PMA review process, the FDA generally will conduct an
inspection of the manufacturer's facilities to ensure that the facilities are in
compliance with applicable GMP requirements. If FDA evaluations of both the PMA
application and the manufacturing facilities are favorable, the FDA may issue
either an approval letter or an approvable letter which usually contains a
number of conditions that must be met in order to secure final approval of the
PMA. When and if those conditions have been fulfilled to the satisfaction of the
FDA, the agency will issue a PMA approval letter, authorizing commercial
marketing of the device for certain indications. If the FDA's evaluation of the
PMA application or manufacturing facilities is not favorable, the FDA will deny
approval of the PMA application or issue a "non-approvable" letter. The FDA may
determine that additional clinical trials are necessary, in which case the PMA
may be delayed for one or more years while additional clinical trials are
conducted and submitted in an amendment to the PMA. Modifications to a device
that is the subject of an approved PMA, its labeling or manufacturing process
may require approval by the FDA of PMA supplements or new PMAs. Supplements to a
PMA often require the submission of the same type of information required for an
initial PMA, except that the supplement is generally limited to that information
needed to support the proposed change from the product covered by the original
PMA.
 
                                       30
<PAGE>   32
 
     A 510(k) clearance will be granted if the submitted information establishes
that the proposed device is "substantially equivalent" to a legally marketed
Class I or Class II medical device or a Class III medical device for which the
FDA has not called for PMAs. The FDA recently has been requiring more rigorous
demonstration of substantial equivalence than in the past, including in some
cases requiring submission of clinical data. The FDA may determine that the
proposed device is not substantially equivalent to a predicate device, or that
additional information is needed before a substantial equivalence determination
can be made. It generally takes from four to 12 months from submission to obtain
510(k) premarket clearance, but may take longer. The FDA may determine that a
proposed device is not substantially equivalent to a legally marketed device, or
that additional information is needed before a substantial equivalence
determination can be made. A "not substantially equivalent" determination, or a
request for additional information, could prevent or delay the market
introduction of new products that fall into this category. For any devices that
are cleared through the 510(k) process, modifications or enhancements that could
significantly affect safety or effectiveness, or constitute a major change in
the intended use of the device, will require new 510(k) submissions.
 
     If human clinical trials of a device are required, whether for a 510(k) or
a PMA, and the device presents a "significant risk," the sponsor of the trial
(usually the manufacturer or the distributor of the device) will have to file an
investigational device exemption ("IDE") application prior to commencing human
clinical trials. The IDE application must be supported by data, typically
including the results of animal and laboratory testing. If the IDE application
is approved by the FDA and one or more appropriate Institutional Review Boards
("IRBs"), human clinical trials may begin at a specific number of
investigational sites with a specific number of patients, as approved by the
FDA. If the device presents a "nonsignificant risk" to the patient, a sponsor
may begin the clinical trial after obtaining approval for the study by one or
more appropriate IRBs without the need for FDA approval. Submission of an IDE
does not give assurance that the FDA will approve the IDE and, if it is
approved, there can be no assurance that the FDA will determine that the data
derived from these studies support the safety and efficacy of the device or
warrant the continuation of clinical studies. Sponsors of clinical trials are
permitted to sell investigational devices distributed in the course of the study
provided such compensation does not exceed recovery of the costs of manufacture,
research, development and handling. An IDE supplement must be submitted to and
approved by the FDA before a sponsor or investigator may make a change to the
investigational plan that may affect its scientific soundness or the rights,
safety or welfare of human subjects.
 
     The Company has obtained clearance from the FDA under Section 510(k) of the
FDC Act to market its SafeSnap line of syringes, which are currently regulated
as Class II devices. The Company has made modifications to its devices which the
Company believes do not require the submission of new 510(k) notices. There can
be no assurance, however, that the FDA would agree with any of the Company's
determinations not to submit a new 510(k) notice for any of these changes or
would not require the Company to submit a new 510(k) notice for any of the
changes made to the device. If the FDA requires the Company to submit a new
510(k) notice for any device modification, the Company may be prohibited from
marketing the modified device until the 510(k) notice is cleared by the FDA. The
Company currently has five product lines under development, a winged butterfly
set, an arterial-venous fistula set, a blood gas syringe, a needleless vial
adapter and a phlebotomy device. These products have not been specifically
classified by the FDA. The Company expects such products to be subject to 510(k)
premarket clearance as Class II devices based upon the FDA's treatment of
similar products on the market. There can be no assurance, however, that the FDA
will not require PMA applications for one or more of these products under
development. Further, there can be no assurance that the Company will be able to
obtain necessary regulatory approvals or clearances for these products on a
timely basis or at all, and the delays in receipt of or failure to receive such
approvals or clearances, the loss of previously received clearances, limitations
on intended use imposed as a condition of such approvals or clearances, or
failure to comply with existing or future regulatory requirements could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
     Devices manufactured or distributed by the Company pursuant to FDA
clearance or approvals are subject to pervasive and continuing regulation by FDA
and certain state agencies. Manufacturers of medical devices for marketing in
the United States are required to adhere to applicable regulations setting forth
 
                                       31
<PAGE>   33
 
detailed GMP requirements, which include testing, control and documentation
requirements. Manufacturers must also comply with Medical Device Reporting
("MDR") requirements that a firm report to the FDA any incident in which its
product may have caused or contributed to a death or serious injury, or in which
its product malfunctioned and, if the malfunction were to recur, it would be
likely to cause or contribute to a death or serious injury. Labeling and
promotional activities are subject to scrutiny by the FDA and, in certain
circumstances, by the Federal Trade Commission. Current FDA enforcement policy
prohibits the marketing of approved medical devices for unapproved uses.
 
     The Company is subject to routine inspection by the FDA and state agencies,
such as the California Department of Health Services, for compliance with GMP
requirements, MDR requirements, and other applicable regulations. The FDA has
proposed certain changes to the GMP regulations that would, among other things,
require design controls and maintenance of service records, which, if finalized,
would likely increase the cost of complying with GMP requirements. Changes in
existing requirements or adoption of new requirements could have a material
adverse effect on the Company's business, financial condition and results of
operation. There can be no assurance that the Company will not incur significant
costs to comply with laws and regulations in the future or that laws and
regulations will not have a material adverse effect upon the Company's business,
financial condition or results of operation.
 
     The Company also is subject to numerous federal, state and local laws
relating to such matters as safe working conditions, manufacturing practices,
environmental protection, fire hazard control and disposal of hazardous or
potentially hazardous substances. There can be no assurance that the Company
will not be required to incur significant costs to comply with such laws and
regulations in the future or that such laws or regulations will not have a
material adverse effect upon the Company's ability to do business.
 
     The sale and distribution of the Company's medical devices outside the
United States are subject to foreign requirements that vary widely from country
to country. The Company's SafeSnap syringes have been approved by the Japanese
Ministry of Health for sale in Japan. The time required to obtain approval or
clearance required by other foreign countries may be longer or shorter than that
required for FDA approval or clearance and the requirements may differ. There
can be no assurance that the Company will be able to obtain necessary regulatory
approvals or clearances in countries in which it wants to introduce its
products. The Company relies upon the companies selling its products in foreign
countries to obtain the necessary regulatory approvals for such sales in those
countries. Generally, devices having 510(k) clearance may be exported without
further FDA authorization.
 
     Sales of the Company's products in Europe are subject to various
regulations, including directives adopted by the European Union ("EU"). The
Company is in the process of implementing ISO 9002, a certification showing that
the Company's procedures and manufacturing facilities comply with standards for
quality assurance and manufacturing process control. Such certification, along
with European Medical Device Directive ("MDD") certification, would evidence
compliance with requirements enabling the Company to affix the CE Mark to its
current products. The CE Mark denotes conformity with European standards for
safety and allows certified devices to be placed on the market in all EU
countries. After June 1998, medical devices may not be sold in EU countries
unless they display the CE Mark. There can be no assurance that the Company will
obtain the right to affix the CE Mark prior to such time.
 
PATENTS
 
     The Company owns the rights to three patents, U.S. Nos. 5,205,824, dated
April 27, 1993, 5,308,329, dated May 3, 1994, and 5,401,246, dated March 28,
1995, for a retractable syringe with a closed barrel (the SafeSnap design) and
certain designs associated with the development of this product. These three
patents were developed by and filed under the names of Matthew S. Mazur, the
Company's founder, as to U.S. No. 5,208,824, and Messrs. Mazur and Carlos H.
Manjarrez, the Company's Vice President of Research and Development, as to U.S.
Nos. 5,308,329 and 5,401,246. Messrs. Mazur and Manjarrez have assigned all
their rights and interests under these patents to the Company.
 
                                       32
<PAGE>   34
 
     The Company has also obtained a paid-up license for a fourth patent related
to its technology, U.S. No. 4,710,170, dated December 1, 1987, for an
Anti-Needle Strike and Anti-Drug Abuse Syringe from Habley Medical Technology
Corporation. This license grants to the Company the exclusive right to make, use
and sell products incorporating the patent rights or claims solely for
applications within the medical field. The license agreement also reserves to
the licensor the non-exclusive right to make, use and sell products which are
not for administration or withdrawal of pharmaceuticals or other fluids by a
syringe of a type described in the patent. This license is a paid-up license
with the last payment in the amount of $212,500, due December 31, 1996, being
made from the proceeds of this offering. The Company believes the combination of
these patents and this license represent a significant competitive barrier in
the retractable safety syringe industry. The Company has undertaken and intends
to aggressively pursue the necessary steps to file claims for international
patent rights in numerous countries. However, despite the patent protection and
despite certain trade secrets of the Company, there can be no assurance that the
patents or trade secrets will prove to be of value.
 
FACILITIES
 
     The Company leases a 55,000 square foot headquarters and manufacturing
facility in San Diego, California. The term of the lease expires December 31,
1998, with two options to renew for consecutive periods of three years each.
 
EMPLOYEES
 
     As of August 1, 1996, the Company employed 70 people including four
research and development employees, 36 in operations, two in facilities, 21 in
sales and marketing employees and seven in general and administration. The
Company's employees are not represented by a labor union, and the Company
believes its employee relations are good.
 
LEGAL PROCEEDINGS
 
     On December 4, 1995, a complaint by plaintiffs Barry L. Rosenblatt, World
Video Movies, Ltd., whose representative is Roy K. Black, and Richard Caras,
against the Company, Matthew S. Mazur and James R. Yarter, was filed in the
United States District Court for the Southern District of California, Case No.
95-3862H(RBB). The complaint alleges the plaintiffs purchased the Company's
Series E Preferred Stock in reliance upon fraudulent misrepresentations of
projections concerning sales, revenues, profits and production capabilities of
the Company. The complaint seeks damages of $1,560,000, together with interest,
attorneys' fees and costs, or recision and recovery of the $1,560,000, plus
interest and attorneys' fees and costs. The Company believe this suit is without
merit and is vigorously contesting the action, which has been withdrawn once and
dismissed once without prejudice. Following its dismissal, the complaint was
refiled. On August 6, 1996, the Company filed a motion for summary judgment to
dispose of all of the plaintiffs' claims.
 
     On June 28, 1996, a complaint by plaintiffs G.C. Investments LLC, whose
representative is Brian L. Greenspun (a former Director of the Company), and The
Medicine Partners, whose representative is Andrew G. Bluhm (a former Director of
the Company), was filed in the United States District Court for the Southern
District of California, Case No. 96-1187H(CGA). The complaint alleges the
plaintiffs purchased the Company's Series E Preferred Stock in reliance upon
fraudulent misrepresentations of projections concerning sales, revenues, profits
and the intended use of the invested funds. The complaint seeks damages of
$8,000,000, together with interest, attorneys' fees, costs and punitive damages.
The Company believes this suit is without merit and is vigorously contesting the
action. On August 13, 1996, the Company filed a motion to dismiss the action for
failure to state a claim.
 
     If any of the pending actions were successfully prosecuted against the
Company, the results could have a material adverse effect upon the Company's
financial position, results of operations, cash flows and ability to conduct
business.

     The Company is subject to certain claims and disputes arising in the normal
course of its business or fund raising efforts. The Company believes the
disposition of these matters will not have a material adverse effect on its
financial position, results of operations or ability to conduct business.
 
ENVIRONMENTAL MATTERS
 
     The Company believes its operations are currently in compliance in all
material respects with applicable Federal, state, and local laws, rules,
regulations and ordinances regarding the discharge of materials into the
environment. Such compliance has no material impact upon the Company's capital
expenditures, earnings or competitive position, and no capital expenditures for
environmental control facilities are planned.

     Securities Exchange Act of 1934, as amended (the "Exchange Act"), and is

     securities. Shares of Common Stock subject to options or warrants currently
     exercisable or exercisable within 60 days of September 1, 1996, are deemed
     outstanding for computing the percentage of the person holding such options
     but are not deemed outstanding for computing the percentage of any other

                              CERTAIN TRANSACTIONS
 
     Carl R. Brown, the senior partner of the law firm of Brown, Martin, Haller

                          DESCRIPTION OF CAPITAL STOCK
 
     The following description of the capital stock of the Company and the
Company's Amended and Restated Articles of Incorporation and Bylaws is a summary
and qualified in its entirety by the Company's Amended and Restated Articles of
Incorporation and Bylaws, which are included as exhibits to the Registration
Statement of which this Prospectus is a part, and by relevant provisions of the
California Corporations Code. At the closing of the offering the outstanding
shares of the Company's Preferred Stock will be converted automatically to
shares of the Company's Common Stock.
 
COMMON STOCK
 
     The Company is authorized to issue up to 28,000,000 shares of Common Stock.
The holders of Common Stock have full voting rights, subject to any voting
rights of any shares of Preferred Stock then outstanding, and are entitled to
one vote for each share held of record on each matter submitted to a vote of
stockholders, except that, upon giving notice required by law, shareholders may
cumulate their votes in the election of directors. Under California law, upon
listing of the Company's Common Stock on the Nasdaq National Market and
obtaining 800 shareholders, the Company can amend its Articles of Incorporation
or Bylaws to eliminate cumulative voting for directors. Holders of Common Stock
have no rights to convert their shares
 
                                       40
<PAGE>   42
 
into other securities or have their shares redeemed, no preemptive rights or
other rights to subscribe for additional securities. Subject to preferences that
may be applicable to any shares of Preferred Stock then outstanding, the holders
of the shares of Common Stock will be entitled to receive such dividends, if
any, as may be declared by the Board of Directors out of legally available funds
and to share ratably in any distribution to the stockholders, including any
distributions upon liquidation of the Company.
 
PREFERRED STOCK
 
     All of the Company's outstanding Preferred Stock will be converted into
Common Stock upon the closing of this offering pursuant to the terms of the
Preferred Stock. Immediately after the conversion of the Preferred Stock into
Common Stock, there will be no Preferred Stock outstanding and the Company will
be authorized to issue 12,000,000 shares of Preferred Stock that is undesignated
as to terms and preferences. Under California law and the Company's Amended and
Restated Articles of Incorporation, the Board of Directors is authorized,
without further shareholder approval, to issue Preferred Stock in one or more
classes or series and to fix the voting rights, liquidation preferences,
dividend rights, repurchase rights, conversion rights, redemption rights and
terms, including sinking fund provisions, and certain other rights and
preferences of the Preferred Stock. Accordingly, although it currently has no
intention of doing so, the Board of Directors of the Company may, without
shareholder approval, issue shares of or class or series of Preferred Stock with
voting and conversion rights which could adversely affect the voting power and
the dividend and other rights of the holders of Common Stock. In addition, the
existence of undesignated Preferred Stock may have the effect of discouraging,
delaying, deferring or preventing an attempt, through acquisition of a
substantial number of shares of Common Stock, to acquire control of the Company
with a view to effecting a merger, sale or exchange of assets or a similar
transaction. The anti-takeover effects of the undesignated Preferred Stock may
deny shareholders the receipt of a premium on their Common Stock and may also
have a depressive effect on the market price of the Common Stock.
 
WARRANTS AND OPTIONS
 
     As of August 31, 1996, the Company had issued options to purchase 1,377,000
shares of Common Stock to employees, directors and consultants pursuant to the
Option Plan with a weighted average exercise price of $1.63 per share.
 
     The Company has also issued warrants to purchase shares of its Common
Stock. The Company has issued warrants to acquire up to 1,300,000 shares of
Common Stock at $14.00 per share. Those warrants expire in December 1997.
Additionally, the Company has issued warrants for 223,000 shares of Common Stock
at $8.00 per share which expire in August 2001, 232,001 shares of Series E
Preferred Stock at $7.50 per share which expire from December 1997 to February
1998, 50,727 shares at $3.50 per share which expire from July to August 1999,
and 14,468 shares of Common Stock at $1.50 per share which expire from November
1998 to May 1999.
 
     In addition, at such time as the Company is qualified to file a
registration statement on Form S-3 under the Securities Act, the holders of
warrants to purchase 213,334 shares of Series E Preferred Stock will be entitled
to cause the Company to register under the Securities Act the sale of all of the
Common Stock held by such warrant holders, including the Common Stock underlying
their Series E Preferred Stock. Upon the written request by the holders of at
least 20% of the Common Stock underlying such Series E Preferred Stock, the
Company shall be required to prepare and file a registration statement on Form
S-3 at its expense. If less than 90% of the Common Stock is sold pursuant to
such registration statement, then the Company shall be required to prepare and
file an additional registration statement for the remaining unsold shares.
Registration of such shares would result in such shares becoming freely
tradeable without restriction under the Securities Act immediately upon the
effectiveness of such registration.
 
TRANSFER AGENT
 
     The transfer agent for the Common Stock is American Stock Transfer & Trust
Company, New York, New York.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     Upon completion of this offering, the Company will have outstanding
          shares of Common Stock. Of these shares, approximately
shares will be freely tradable without restriction or further registration under
the Securities Act. The remaining           shares of Common Stock held by
existing stockholders upon completion of this offering are "restricted
securities" as defined in Rule 144 promulgated under the Securities Act, and may
only be sold in the public market if such shares are registered under the
Securities Act or sold in accordance with Rule 144 or another exemption from
registration under the Securities Act.
 
     In general, under Rule 144 a person (or group of persons whose shares are
aggregated) who has beneficially owned restricted securities for at least two
years, including persons who may be deemed "affiliates" (as defined in Rule 144)
of the Company, will be entitled to sell, within any three-month period, a
number of shares that does not exceed the greater of (i) 1% of the then
outstanding shares of the Common Stock, or (ii) the average weekly trading
volume in the Common Stock during the four calendar weeks preceding such sale.
Sales under Rule 144 are also subject to certain manner of sale limitations,
notice requirements and the availability of current public information about the
Company. A person who has not been an "affiliate" of the Company for the 90 days
preceding a sale and who has beneficially owned restricted securities for at
least three years will be entitled to sell such shares in the public market
without restriction. Restricted securities properly sold in reliance upon Rule
144 are thereafter freely tradeable without restrictions or registration under
the Securities Act, unless thereafter held by an "affiliate" of the Company. For
purposes of Rule 144,           of the outstanding restricted shares of Common
Stock have been beneficially owned by their holders for over two years.
 
     The Company is unable to estimate the amount, timing or nature of future
sales of outstanding Common Stock. Of the           restricted shares that will
be outstanding upon completion of this offering, executive officers and
directors, holding an aggregate of           shares, have agreed that, for a
period of 180 days from the date of this Prospectus, they will not offer for
sale, sell, solicit an offer to buy, contract to sell, distribute, grant any
option for the sale of or otherwise transfer or dispose of, directly or
indirectly, any shares of Common Stock or any securities convertible into,
exercisable for or exchangeable for any shares of Common Stock without the prior
written consent of the Representative. Of the remaining           restricted
shares,           shares are now eligible or will be eligible for sale under
Rule 144 within 90 days from the date of this Prospectus. See "Underwriting."
 
     The Company has reserved 2,000,000 shares of Common Stock for issuance to
key employees, officers, directors and consultants pursuant to the Company's
Option Plan, and options for 1,377,000 of such shares are outstanding as of the
date of this Prospectus. The Company has further reserved 1,820,196 shares of
Common Stock for issuance upon exercise of outstanding warrants. The existence
of such options and warrants may hinder future equity financing by the Company.
Further, the holders of such warrants and options may exercise them at a time
when the Company would otherwise be able to obtain additional equity capital on
terms more favorable to the Company. In addition, the holders of warrants for
213,334 shares have certain demand registration rights. See "Description of
Capital Stock."

     The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to approval of certain legal matters by
counsel and to various other conditions. The nature of the Underwriters'
obligations is such that they are committed to purchase and pay for all of the
above shares of Common Stock offered hereby if any are purchased.
 
     The Underwriters, through the Representative, have advised the Company that
they propose to offer the shares of Common Stock initially at the public
offering price set forth on the cover page of this Prospectus; that the
Underwriters may allow to selected dealers a concession of $     per share and
that such dealers may reallot a concession not in excess of $     per share to
certain other dealers who are members of the National Association of Securities
Dealers, Inc. After the public offering, the offering price and other selling
terms may be changed by the Underwriters. Application has been made for the
Common Stock to be included on the Nasdaq National Market. The Representative
has advised the Company that it does not intend to confirm sales to any accounts
over which it exercises discretionary authority.
 
     The Underwriters have been granted a 30-day over-allotment option to
purchase up to an aggregate of           additional shares of Common Stock from
the Company at the public offering price less the underwriting discount. If the
Underwriters exercise such over-allotment option, then each of the Underwriters
will have a firm commitment, subject to certain conditions, to purchase
approximately the same percentage thereof as the number of shares of Common
Stock to be purchased by it as shown in the above table bears to the
shares of Common Stock offered hereby. The Underwriters may exercise such option
only to cover over-allotments made in connection with the sale of the shares of
Common Stock offered hereby.
 
     In connection with this offering, the Company has agreed to issue and sell
to the Representative, for nominal consideration, warrants to purchase a number
of shares of Common Stock equal to 10% of the shares of Common Stock in this
offering, exclusive of any shares sold pursuant to the Underwriters'
over-allotment option (the "Representative's Warrant"). The Representative's
Warrant will be exercisable at a price per share equal to 120% of the public
offering price, commencing one year from the date of this Prospectus, and will
continue to be exercisable for a period of four years after such date. The
Representative's Warrant is restricted from sale, transfer, assignment or
hypothecation for a period of one year from the effective date of this offering,
except to officers, partners or successors of the Representative. The exercise
price of the Representative's Warrant and the number of shares of Common Stock
issuable upon exercise thereof are subject to adjustment under certain
circumstances. The Representative's Warrant grants to the holders thereof
certain rights regarding the registration of the Common Stock issuable upon
exercise of the Representative's Warrant.
 
     All executive officers and directors of the Company, as well as certain
shareholders, who own           shares of the Company's Common Stock, have
agreed that for a period of 180 days from the date of this Prospectus, they will
not offer for sale, sell, solicit an offer to buy, contract to sell, distribute,
grant any option for the sale of or otherwise transfer or dispose of, directly
or indirectly, any shares of Common Stock or any
 
                                       43
<PAGE>   45
 
securities convertible into or exercisable for any shares of Common Stock
without the prior written consent of the Representative on behalf of the
Underwriters. See "Shares Eligible for Future Sale."
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including civil liabilities, losses and expenses under the
Securities Act, or to contribute to certain payments the Underwriters may be
required to make in respect thereof.
 
     For a period of one year following the closing of this offering, the
Representative has a right of first negotiation to act as the Company's

and prospects of the Company, the present state of the Company's business
operations, an assessment of the Company's management and the consideration of
the above factors in relation to the market valuation of companies in related
businesses.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
Shareholders of U.S. Medical Instruments, Inc.
 
     In our opinion, the financial statements listed in the accompanying index
present fairly, in all material respects, the financial position of U.S. Medical
Instruments, Inc. (a development stage enterprise) at January 31, 1995 and 1996,
and the results of its operations and its cash flows for the years ended January
31, 1994, 1995 and 1996 and the period from June 19, 1991 (inception) to January
31, 1996, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.
 
     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As described in Note 2 to the
financial statements, the Company is in the development stage, has incurred a
cumulative net loss since inception and is dependent on additional financing in
order to continue its operations and execute its growth strategy. These factors,
among others, raise substantial doubt about the Company's ability to continue as
a going concern. Management's plans to raise additional financing are also
described in Note 2. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

                         U.S. MEDICAL INSTRUMENTS, INC.
                        (A DEVELOPMENT STAGE ENTERPRISE)
 
                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- THE COMPANY
 
     U.S. Medical Instruments, Inc. (the "Company") was incorporated in
California on June 19, 1991. The Company's business is to design, develop,
manufacture and market safety medical products. The Company's initial product is
a safety syringe which the Company markets to acute care (hospitals), alternate
care (clinics, hospices, etc.), and retail facilities throughout the United
States and worldwide.
 
NOTE 2 -- DEVELOPMENT STAGE ACTIVITIES AND DEPENDENCY ON ADDITIONAL FINANCING
 
     The Company is considered a development stage Company as defined in FASB
No. 7 "Accounting and Reporting by Development Stage Enterprises." The Company's
primary activities since inception have included developing its proprietary
safety medical products, acquiring and securing patents, raising capital to
finance its operations, securing regulatory approval for its products and
designing the manufacturing process for its initial product line. Revenues from
inception to January 31, 1996 have not been significant. The cumulative net loss
incurred during the development stage from inception to January 31, 1996 is
$21,977,000 and from inception to April 30, 1996 is $23,698,000 (unaudited). The
Company had negative working capital of $90,000 and $1,089,000 at January 31,
1996 and April 30, 1996 (unaudited), respectively.
 
     Management plans to pursue a growth strategy for fiscal 1997. The Company
is dependent on additional financing to execute that growth strategy and to
continue its operations. Management believes that the proceeds of the planned
initial public offering of the Company's stock and/or private financing, if
successful, will be sufficient to fund its operations and anticipated growth for
at least the next twelve months. There can be no assurance that these
anticipated financings will be consummated. The financial statements do not
include any adjustments that might result from the outcome of this uncertainty.
 
NOTE 3 -- SIGNIFICANT ACCOUNTING POLICIES
 
FINANCIAL STATEMENT PREPARATION
 
     The preparation of financial statements, in conformity with generally
accepted accounting principles, requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
INVENTORIES
 
     Inventories are valued at the lower of cost (determined by the first-in,
first-out method) or market.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment is recorded at cost and depreciated using the
straight-line method over estimated useful lives of three to ten years.
Expenditures which substantially increase value or extend useful lives are
capitalized. Maintenance and repairs are expensed as incurred. Leasehold
improvements are capitalized and amortized over the remaining lease term.
 
INTANGIBLE ASSETS
 
     Intangible assets are recorded at cost and amortized using the
straight-line method over their estimated remaining useful lives, which
currently range from ten to twelve years.

                        (A DEVELOPMENT STAGE ENTERPRISE)
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
LONG-LIVED ASSETS
 
     The Company assesses potential impairments to its long-lived assets when
there is evidence that events or changes in circumstances indicate that the
carrying amount of an asset may not be recovered. An impairment loss would be
recognized when the asset's fair value is less than its carrying amount. No such
impairment losses have been identified by the Company.
 
MAJOR CUSTOMERS AND CONCENTRATIONS OF CREDIT RISK
 
     Financial instruments which potentially expose the Company to
concentrations of credit risk consist primarily of trade accounts receivable. As
of January 31, 1996, approximately 96% of trade receivables were from one
customer. To reduce credit risk, the Company performs ongoing credit evaluations
of its customers' financial condition. The Company does not generally require
collateral on credit sales to its customers. For the years ended January 31,
1994, 1995, and 1996, approximately 100%, 95% and 67% of net sales were to one
customer, two customers and one customer, respectively. The Company has not
experienced significant credit losses and maintains a reserve for potential
credit losses. As of and for the three month period ended April 30, 1996
approximately $8,000 (unaudited) of trade receivables and 86% (unaudited) of net
sales were to one customer.
 
DEFERRED FINANCING COSTS AND DEBT DISCOUNT
 
     Deferred financing costs and debt discounts recorded in connection with the
issuance of long-term debt are amortized using the interest method over the term
of the debt.
 
INCOME TAXES
 
     Current income tax expense is the amount of income taxes expected to be
payable in the current year. Deferred tax assets and liabilities are computed
for both the expected future tax consequences resulting from the differences in
financial reporting and tax bases of assets and liabilities and for the expected
future tax benefit to be derived from tax loss and tax credit carryforwards.
Deferred income tax expense (benefit) is the net change during the period in the
deferred income tax asset or liability, net of valuation allowances (Note 8).
 
REVENUE
 
     Revenue from product sales is recognized upon shipment, net of an allowance
for estimated sales returns. Net sales for the year ended January 31, 1996 and
the three months ended April 30, 1996 included $246,000 and $192,000 (unaudited)
from a customer in Japan. Such sales were made under an executed letter of
credit.
 
RESEARCH AND DEVELOPMENT
 
     Research and development costs are expensed as incurred.
 
REGULATORY APPROVAL COSTS
 
     Regulatory approval costs are expensed as incurred.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
STOCK-BASED COMPENSATION ACCOUNTING
 
     Statement of Financial Accounting Standards No. 123 ("FAS 123"),
"Accounting for Stock-Based Compensation" is effective beginning with the
Company's first quarter of fiscal year 1997. In the opinion of management,
adoption will not have a material effect on the Company's financial position or
results of operations. Upon adoption of FAS 123, the Company will continue to
measure compensation expense for its stock-based employee compensation plans
using the intrinsic value method prescribed by APB Opinion No. 25, "Accounting
for Stock Issued to Employees" and will provide pro forma disclosures of results
of operations as if the fair value-based method prescribed by FAS 123 had been
applied in measuring compensation expense.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
     The carrying amounts shown for the Company's financial instruments, due to
their relative short term nature, are not materially different from the
estimates of their related fair values.
 
PRO FORMA NET LOSS PER SHARE (UNAUDITED)
 
     Pro forma net loss per share is computed using the weighted average number
of common and common equivalent shares, if dilutive, outstanding during the
period. All securities issued by the Company during the twelve months preceding
the filing date of its initial public offering and thereafter through the
effective date have been included in the calculation of weighted average shares
outstanding as if they were outstanding for all periods in which such
information is presented. The pro forma net loss per share also includes the
effect of conversion to Common Stock of the Company's Preferred Stock which is
convertible at the option of the holder or automatically in the event of an
initial public offering. Historical net loss per share amounts are not presented
because such amounts are not believed to be meaningful.
 
INTERIM FINANCIAL STATEMENTS
 
     The interim financial statements included herein are unaudited. In the
opinion of management, all adjustments, consisting only of normal recurring
adjustments, necessary for fair presentation of such financial statements have
been included. The results of operations for the three months ended April 30,
1996 are not necessarily indicative of the results to be expected for the year.
 
PRO FORMA SHAREHOLDERS' EQUITY (UNAUDITED)
 
     Pro forma shareholders' equity of the Company at April 30, 1996 gives
effect to the automatic conversion of Series A, B, C, D, E and F convertible
Preferred Stock into an equal number of shares of Common Stock upon the closing
of the Company's initial public offering.

     On August 5, 1994, the Company had an outstanding promissory note payable
to a shareholder with a face value of $851,000, accrued interest of $31,000 and
an unamortized discount of $69,000. The note was settled in fiscal 1995 by
issuing the shareholder 142,857 shares of Series D Preferred Stock valued at
$800,000, a warrant to purchase 228,000 shares of Common Stock at $.56 per
share, and cash of $82,000. The warrants were valued by management at $107,000.
The Company recorded a loss on extinguishment of debt of $176,000 on this
transaction.
 
     During fiscal 1993, the Company acquired the exclusive long-term license to
certain patents, technical data and trade styles relating to its safety syringe.
During fiscal 1994, the Company paid $50,000 in minimum royalties related to
this agreement. In December 1994, the Company exercised its option to discharge
its royalty obligation in full by paying $750,000 in December 1994 and agreeing
to make four semi-annual payments of $212,500 each beginning on June 30, 1995.
The Company has capitalized $1,496,000 representing the December 1994 payment
and the present value of all future payments under the agreement, using an
effective interest rate of 10%, and is amortizing such costs over the remaining
ten year life of the patent. Under the terms of the agreement, if the Company
fails to make a semi-annual payment within ten days after written notice, the
Company shall forfeit its paid up, royalty-free license.
 
     During February 1996, the Company renegotiated the two secured promissory
notes discussed above. Under the new terms, the Company was required to make a
lump sum payment of $120,000 on February 23, 1996 and interest only payments of
$7,600 per month (8.25% per annum) commencing March 13, 1996 and ending on
August 13, 1996 at which time the Company had the option to pay the remaining
outstanding balance. If the Company had exercised its option to pay the note on
August 13, 1996, the Company would have been entitled to a reduction of the
principal amount of $150,000. The Company did not elect to exercise

NOTE 6 -- SHAREHOLDERS' EQUITY
 
     In April 1993, the shareholders approved a five for one stock split and a
recapitalization plan whereby the common shareholders converted their common
shares into Preferred Stock Series A, Series B, Series C, or Series D, depending
on the price originally paid for such common shares. All outstanding shares of
Series A and C, 554,195 shares of Series B, and 363,825 shares of Series D were
former common shares converted pursuant to this plan. In August 1994, the
shareholders approved an increase in the authorized shares to 12 million
preferred shares and 28 million common shares. The following preferred shares

WARRANTS
 
     In connection with the issuance of short-term notes payable to directors
and shareholders, the Company issued warrants to purchase 17,656 and 81,184
shares of Common Stock at $.56 per share during the years ended January 31, 1994
and 1995, respectively. The exercise price of the warrants granted was equal to
the fair market value of the Company's Common Stock at the date of grant, as
determined by the Board of Directors. Approximately 32,000 warrants were
exercised during fiscal year 1995 and the remaining warrants are exercisable at
any time through February 2004. The value of the warrants issued in fiscal 1994
was considered immaterial. The warrants issued in fiscal 1995 were valued by
management at $19,000 and charged to interest expense.
 
     During fiscal 1994, in connection with the issuance of a long-term note due
to a shareholder, the Company issued warrants to purchase 50,000 shares of
Series D Preferred Stock at $5.60 per share. The warrants may be exercised at
anytime through November 1998. The fair value of these warrants has been
recorded as a discount to the related debt and charged to expense ratably over
the debt repayment terms. In August 1994, the shareholder note was settled in
exchange for 142,857 shares of Series D Preferred Stock valued at $800,000, a
warrant to purchase 228,000 shares of Common Stock at $.56 per share, and cash.

Stock, the Company issued warrants to purchase 213,334 shares of Series E
Preferred Stock at $7.50 per share. The proceeds of the issuance were allocated

Company issued warrants to purchase 18,667 shares of Series E Preferred Stock at
$7.50 per share to a third party as payment for a finder's fee for the above
transaction. These warrants were valued by management at $75,000 and recorded as

warrants issued in connection with this transaction are exercisable at any time
until expiration on January 31, 1998.
 
     During fiscal 1996, the Company issued demand notes payable to certain
shareholders totaling $440,000 together with 52,800 warrants to purchase Common
Stock. The notes bore interest at 8% per annum and were paid in full as of
January 31, 1996. The Common Stock purchase warrants have an exercise price of
$.75 per share, which was the fair market value at the date of grant, as
determined by the Board of Directors, and are exercisable over a period of
between three months and five years from the date of grant. The warrants were
valued by management at $25,000 and charged to interest expense.
 
     During fiscal 1996, the Company issued convertible secured notes payable to
a shareholder for a total of $4,000,000 together with warrants to purchase
106,667 shares of Series E Preferred Stock at $7.50 per share and warrants to

August 1998 and bore interest at 9% payable quarterly. The lender had the right
to demand payment of the convertible note on or after January 31, 1996. The
notes were secured by the Company's patents, plastic injection molds, and
automated assembly equipment. At any time prior to August 1998 or until the
notes were paid, the notes were convertible into Series E Preferred Stock at
$7.50 per share. The proceeds of the issuance were allocated based upon the
estimated fair value of the securities issued. The fair value, as determined by
management, of the Preferred Stock warrants of $246,000 has been recorded as a
discount to the related debt and charged to expense ratably over the minimum
term of the debt.

NOTE 7 -- STOCK OPTION PLAN
 
     During fiscal 1994, the Board of Directors approved a stock option plan
("the Plan") which provides for the granting of options or stock purchase rights

grant of such option. At January 31, 1996, options for 221,585 common shares
were available for future grant under the Plan and 447,958 were exercisable. At
April 30, 1996 options for 371,585 common shares (unaudited) were available for
future grant under the Plan and 398,375 common shares (unaudited) were

     As of January 31, 1996, the Company has Federal and state net operating
loss carryforwards of approximately $17,000,000 and $8,500,000, respectively.
The Federal and state net operating loss carryforwards expire beginning in 2008
and 1998, respectively. The Company also has research and development credit
carryforwards for Federal and state tax reporting purposes totaling
approximately $166,000 and $87,000, respectively, which expire at various times
through 2009. Based upon the Company's lack of prior earnings history,
realization of the Company's deferred tax assets does not meet the more likely
than not criteria and are fully reserved through a valuation allowance.
 
     No current tax provision or benefit was recorded for the years ended
January 31, 1994, 1995 or 1996, due to net losses of the Company.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company believes that it has incurred an ownership change in the year
ended January 31, 1995. As a result, the Company believes that its ability to
utilize its current net operating loss and credit carryforwards, and to realize
the benefit of future tax deductions in subsequent periods will be subject to
annual limitations of approximately $1,600,000 for net operating losses
generated through the year ended January 31, 1995. The Company expects that a
second change may occur as a result of the anticipated public offering of the
Common Stock which may subject the Company to further annual limitations.

     The Company has been sued by two groups of investors holding shares of
Series E Preferred Stock. In an action filed in 1995, the first group of

tion capabilities of the Company. The plaintiffs seek damages of $1,560,000
together with interest and attorneys' fees and costs. The suit has been
withdrawn once and dismissed once with leave to amend. The Company has filed a
summary judgment motion to dispose of all of the plaintiffs' claims. In an
action filed in June 1996, the second group of Series E Preferred Stock
shareholders, comprised of G.C. Investments LLC, whose representative is Brian
L. Greenspun, and The Medicine Partners, whose representative is Andrew G.
Bluhm, filed an action containing allegations similar to those contained in the
first action with the addition of fraudulent misrepresentation of the intended
use of funds. The plaintiffs seek damages of $8,000,000 together with interest
and attorneys' fees and costs. The Company believes these suits are without
merit and is vigorously contesting the actions. Management believes that the
ultimate resolution of these matters will not have a material adverse effect on
the Company's financial position, results of operations, cash flows or ability
to conduct business.
 
     The Company is subject to certain claims and disputes arising in the normal
course of its business. Although there can be no assurances, management believes
that the disposition of these matters will not have a material adverse effect on
the Company's financial position, results of operations, cash flows or ability
to conduct business.

NOTE 12 -- SUBSEQUENT EVENTS
 
     In August 1996, the Company entered into an agreement with Merrill Lynch
Business Financial Services, Inc. ("Merrill Lynch") whereby Merrill Lynch will
provide the Company up to $2,300,000 in working capital. The interest rate is
variable based on 2.65% plus the 30-day Commercial Paper Rate (as published in
the Wall Street Journal). As of July 31, 1996, the interest rate was 8.07%. The
loan is subject to an annual fee and is secured with a security interest in
assets pledged by a shareholder of the Company. In connection with the
shareholder's agreement to pledge the assets as security for the working capital
loan discussed above, the Company granted the shareholder a warrant to purchase
223,000 shares of the Company's Common Stock at $8.00 per share and has agreed
to indemnify the shareholder for certain potential tax liabilities associated
with this transaction. The estimated fair market value of the warrant will be
recognized as interest expense over the one year term of the loan agreement.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Company's Amended and Restated Articles of Incorporation eliminates the
personal liability of the directors of the Company for monetary damages to the
fullest extent permitted by California law, for breach of fiduciary duties as a
director of the Company except: (i) for any breach of the directors' duty of
loyalty to the Company or its stockholders; (ii) for acts for omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law; (iii) for unlawful dividends or distributions; or, (iv) for any transaction
from which the director derived an improper personal benefit. The Company's
Amended and Restated Articles of Incorporation also permit the Company to
indemnify its directors and officers to the fullest extent permitted by
California law.
 
     Article VI of the Company's Bylaws permits the Company to indemnify its
directors, officers, employees and agents to the maximum extent permitted by the
California General Corporation Law. Section 317 of the California General
Corporation Law provides that a corporation has the power to indemnify and hold
harmless a director, officer, employer, or agent of the corporation who is or is
made a party or is threatened to made a party to any threatened, action, suit or
proceeding, whether civil, criminal, administrative or investigative, against
all expense, liability and loss actually and reasonably incurred or suffered by
such person in connection with such a proceeding if he or she acted in good
faith and in a manner he or she reasonably believed to be in the best interest
of the corporation, and, with respect to any criminal proceeding, had no
reasonable cause to believe that the conduct was unlawful. If it is determined
that the conduct of such person meets these standards, such person may be
indemnified for expenses incurred and amounts paid in such proceeding if
actually and reasonably incurred in connection therewith.
 
     If such a proceeding is brought by or on behalf of the corporation (i.e., a
derivative suit), such person may be indemnified against expenses actually and
reasonably incurred if such person acted in good faith and in a manner
reasonably believed to be in the best interest of the corporation and its
shareholders. There can be no indemnification with respect to any matter as to
which such person is adjudged to be liable to the corporation unless and only to
the extent that the court in which such action or suit was brought shall
determine upon application that, despite such adjudication but in view of all of
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses as the court shall deem proper.
 
     Where any such person is successful in any such proceeding, such person is
entitled to be indemnified against expenses actually and reasonably incurred by
him or her. In all other cases (unless order by a court),
 
                                      II-1
<PAGE>   72
 
indemnification is made by the corporation upon determination by it that
indemnification of such person is proper in the circumstances because such
person has met the applicable standard of conduct.
 
     A corporation may advance expenses incurred in defending any such
proceeding upon receipt of an undertaking to repay any amount so advanced if it
is ultimately determined that the person is not eligible for indemnification.
 
     The indemnification rights provided in Section 317 are not exclusive of
additional rights to indemnification for breach of duty to the corporation and
its shareholders to the extent additional rights are authorized in the
corporation's articles of incorporation and are not exclusive of any other
rights to indemnification under any bylaw, agreement, vote of shareholders or
disinterested directors or otherwise, both as to action in his or her office and
as to action in another capacity while holding such office.

106,667 shares of Series E Preferred Stock. Each Warrant entitles the holder to

ITEM 17.  UNDERTAKINGS
 
     (a) Registrant hereby undertakes:
 
          (1) to file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) to including any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) to reflect in the prospectus any facts or events arising after
        the effective date of the Registration Statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the Registration Statement;
 
             (iii) to include any material information with respect to its plan
        of distribution not previously disclosed in the Registration Statement
        or any material change to such information in the Registration
        Statement.
 
          (2) To provide to the Underwriters at the closing specified in the
     Underwriting Agreement certificates in such denominations and registered in
     such names as required by the Underwriters to permit prompt delivery to
     each purchaser.
 
          (3) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as a
     part of the Registration Statement in reliance upon Rule 430A and contained
     in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1)
     or (4) or 497(h) under the Securities Act shall be deemed to be part of
     this Registration Statement as of the time it was declared effective.
 
          (4) For purposes of determining any liability under the Securities Act
     of 1933, each post-effective amendment that contains a form of prospectus
     shall be deemed to be a new registration statement relating to the
     securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy is expressed in the Act and will be governed by the final adjudication of
such issue.

RODMAN & RENSHAW, INC.
[                 ]
c/o Rodman & Renshaw, Inc.

New York, New York  10281

On behalf of the Several
Underwriters named in 
Schedule I attached hereto.

Ladies and Gentlemen:

         U.S. Medical Instruments, Inc., a California corporation (the
"Company") proposes to sell to you and the other underwriters named in Schedule
I attached hereto (the "Underwriters"), for whom you are acting as the
representatives (the "Representatives"), an aggregate of           shares (the
"Firm Shares") of the Company's Common Shares, no par value (the "Common
Stock"), to be issued and sold by the Company. In addition, the Company proposes
to grant to the Underwriters an option to purchase up to an additional        
shares (the "Option Shares"), of Common Stock for the purpose of covering
over-allotments in connection with the sale of the Firm Shares. The Firm Shares
and the Option Shares are together called the "Shares."

         1.       Sale and Purchase of the Shares.  On the basis of the
representations, warranties and agreements contained in, and subject to the
terms and conditions of, this Agreement:

                  (a)      The Company agrees to issue and sell the Shares to 
         the several Underwriters, and each of the Underwriters agrees,
         severally and not jointly, to purchase at the purchase price per share
         of Common Stock of $_____ (the "Initial Price"), the aggregate number
         of Firm Shares set forth opposite such Underwriter's name in Schedule I
         attached hereto. The Underwriters agree to offer the Firm Shares to the
         public as set forth in the Prospectus.

                  (b)      The Company grants to the several Underwriters an 
         option to purchase all or any part of the number of Option Shares at
         the Initial
<PAGE>   2
         Price. The number of Option Shares to be purchased by each Underwriter
         shall be the same percentage (adjusted by the Representatives to
         eliminate fractions) of the total number of Option Shares to be
         purchased by the Underwriters as such Underwriter is purchasing of the
         Firm Shares. Such option may be exercised only to cover over-allotments
         in the sales of the Firm Shares by the Underwriters and may be
         exercised in whole or in part at any time on or before 12:00 noon, New
         York City time, on the business day before the Firm Shares Closing Date
         (as defined below), and from time to time thereafter within 30 days
         after the date of this Agreement, upon written or telegraphic notice,
         or verbal or telephonic notice confirmed by written or telegraphic
         notice, by the Representatives to each of the Company no later than
         12:00 noon, New York City time, on the business day before the Firm
         Shares Closing Date or at least two business days before any Option
         Shares Closing Date (as defined below), as the case may be, setting
         forth the number of Option Shares to be purchased and the time and date
         (if other than the Firm Shares Closing Date) of such purchase.

                  (c)      On each Closing Date (as defined below), the Company 
         shall issue and sell to Rodman & Renshaw, Inc. ("Rodman"), individually
         and not as a Representative of the Underwriters, for an aggregate
         purchase price of $.001 per warrant, warrants representing the right of
         Rodman to purchase a number of shares of Common Stock (the "Warrant
         Stock") equal to 10.0% of the aggregate number of shares purchased in
         the Offering, excluding the over-allotment option (which warrants shall
         be evidenced in the form set forth as an exhibit to the Registration
         Statement) (the "Representative's Warrants").

         2.       Delivery and Payment. Delivery by the Company of the Firm 
Shares to the Representatives for the respective accounts of the Underwriters,
and payment of the purchase price by certified or official bank check or checks
payable in New York Clearing House (next day) funds to the Company, shall take
place at the offices of Rodman & Renshaw, Inc., at 225 Liberty Street, 2 World
Financial Center, New York, New York 10281, at 10:00 a.m., New York City time,
on the third business day following the date on which the public offering of the
Shares commences (unless such date is postponed in accordance with the
provisions of Section 10(b)), or at such time and place on such other date, not
later than 10 business days after the date of this Agreement, as shall be agreed
upon by the Company and the Representatives (such time and date of delivery and
payment are called the "Firm Shares Closing Date"). The public offering of the
Shares shall be deemed to have commenced at the time, which is the earlier of
(a) the time, after the Registration Statement (as defined in Section 4 below)
becomes effective, of the release by you for publication of the first newspaper
advertisement which is subsequently published relating to the Shares or (b) the
time, after the Registration Statement becomes effective, when the Shares are
first released by you for offering by the Underwriters or dealers by letter or
telegram.

         In the event the option with respect to the Option Shares is exercised,
delivery by the Company of the Option Shares to the Representatives for the
respective accounts of the Underwriters and payment of the purchase price by
certified or official bank check or checks payable in New York Clearing House
(next day) funds to the Company shall take place at the offices of Rodman &
Renshaw, Inc. specified above at the time and on the date (which may be the same


                                       -2-
<PAGE>   3
date as, but in no event shall be earlier than, the Firm Shares Closing Date)
specified in the notice referred to in Section 1(b) (such time and date of
delivery and payment is called the "Option Shares Closing Date"). The Firm
Shares Closing Date and the Option Shares Closing Dates are called,
individually, a "Closing Date" and, together, the "Closing Dates."

         Certificates evidencing the Shares shall be registered in such names
and shall be in such denominations as the Representatives shall request at least
two full business days before the Firm Shares Closing Date or the Option Shares
Closing Date, as the case may be, and shall be made available to the
Representatives for checking and packaging, at such place as is designated by
the Representatives, on the full business day before the Firm Shares Closing
Date or the Option Shares Closing Date, as the case may be.

         3.       Public Offering. The Company understands that the Underwriters
propose to make a public offering of the Shares, as set forth in and pursuant to
the Prospectus (as defined in Section 4 below), as soon after the effective date
of the Registration Statement and the date of this Agreement as the
Representatives deem advisable. The Company hereby confirms that the
Underwriters and dealers have been authorized to distribute or cause to be
distributed each preliminary prospectus and are authorized to distribute the
Prospectus (as from time to time amended or supplemented if the Company
furnishes amendments or supplements thereto to the Underwriters).

         4.       Representations and Warranties of the Company.

                  The Company represents and warrants to, and agrees with, the
         several Underwriters that:

                           (i)    The Company has filed with the Securities and
                  Exchange Commission (the "Commission") a registration
                  statement, and may have filed one or more amendments thereto,
                  on Form S-1 (Registration No. 333-_____), including in such
                  registration statement and each such amendment a related
                  preliminary prospectus (a "Preliminary Prospectus"), for the
                  registration of the Shares and the Option Shares, in
                  conformity with the requirements of the Securities Act of
                  1933, as amended (the "Act"). In addition, the Company has
                  filed or will promptly file a further amendment to such
                  registration statement, in the form heretofore delivered to
                  you. The Company may also file a related registration
                  statement with the Commission pursuant to Rule 462(b) under
                  the Act for the purpose of registering certain additional
                  Shares, which registration shall be effective upon filing with
                  the Commission. As used in this Agreement, the term "Original
                  Registration Statement" means such registration statement, as
                  amended, on file with the Commission at the time such
                  registration statement becomes effective (including the
                  prospectus, financial statements, exhibits, and all other
                  documents filed as a part thereof or incorporated by reference
                  directly or indirectly therein), provided that such
                  registration statement, at the time it becomes effective, may
                  omit such information as is permitted to be omitted from a
                  registration statement when it becomes effective pursuant to
                  Rule 430A of the General Rules and Regulations promulgated
                  under the Act (the "Regulations"), which information ("Rule
                  430 Information") shall be


                                       -3-
<PAGE>   4
                  deemed to be included in such registration statement when a
                  final prospectus is filed with the Commission in accordance
                  with Rules 430A and 424(b)(1) or (4) of the Regulations; the
                  term "Rule 462(b) Registration Statement" means any
                  registration statement filed with the Commission pursuant to
                  Rule 462(b) under the Act (including the Original Registration
                  Statement and any Preliminary Prospectus or Prospectus
                  incorporated therein at the time the Original Registration
                  Statement becomes effective); the term "Registration
                  Statement" includes both the Original Registration Statement
                  and any Rule 462(b) Registration Statement; the term
                  "Preliminary Prospectus" means each prospectus included in the
                  Registration Statement, or any amendments thereto, before it
                  becomes effective under the Act, the form of prospectus
                  omitting Rule 430A Information included in the Registration
                  Statement when it becomes effective, if applicable (the "Rule
                  430A Prospectus"), and any prospectus filed by the Company
                  with your consent pursuant to Rule 424(a) of the Regulations;
                  and the term "Prospectus" means the final prospectus included
                  as part of the Registration Statement, except that if the
                  prospectus relating to the securities covered by the
                  Registration Statement in the form first filed on behalf of
                  the Company with the Commission pursuant to Rule 424(b) of the
                  Regulations shall differ from such final prospectus, the term
                  "Prospectus" shall mean the prospectus as filed pursuant to
                  Rule 424(b) from and after the date on which it shall have
                  first been used.

                           (ii)    When the Registration Statement becomes
                  effective, and at all times subsequent thereto to and
                  including the Closing Dates, and during such longer period as
                  the Prospectus may be required to be delivered in connection
                  with sales by the Underwriters or a dealer, and during such
                  longer period until any post-effective amendment thereto shall
                  become effective, the Registration Statement (and any
                  post-effective amendment thereto) and the Prospectus (as
                  amended or as supplemented if the Company shall have filed
                  with the Commission any amendment or supplement to the
                  Registration Statement or the Prospectus) will contain all
                  statements which are required to be stated therein in
                  accordance with the Act and the Regulations, will comply with
                  the Act and the Regulations, and will not contain any untrue
                  statement of a material fact or omit to state any material
                  fact required to be stated therein or necessary to make the
                  statements therein not misleading, and no event will have
                  occurred which should have been set forth in an amendment or
                  supplement to the Registration Statement or the Prospectus
                  which has not then been set forth in such an amendment or
                  supplement; if a Rule 430A Prospectus is included in the
                  Registration Statement at the time it becomes effective, the
                  Prospectus filed pursuant to Rules 430A and 424(b)(1) or (4)
                  will contain all Rule 430A Information; and each Preliminary
                  Prospectus, as of the date filed with the Commission, did not
                  include any untrue statement of a material fact or omit to
                  state any material fact required to be stated therein or
                  necessary to make the statements therein not misleading;
                  except that no representation or warranty is made in this
                  Section 4(ii) with respect to statement or omissions made in
                  reliance upon and in


                                       -4-
<PAGE>   5
                  conformity with written information furnished to the Company
                  as stated in Section 7(b) with respect to any Underwriter by
                  or on behalf of such Underwriter through the Representatives
                  expressly for inclusion in any Preliminary Prospectus, the
                  Registration Statement, or the Prospectus, or any amendment or
                  supplement thereto.

                           (iii)  If the Company has elected to rely on Rule
                  462(b) and the Rule 462(b) Registration Statement has not been
                  declared effective, then (i) the Company has filed a Rule
                  462(b) Registration Statement in compliance with and that is
                  effective upon filing pursuant to Rule 462(b) and has received
                  confirmation of its receipt and (ii) the Company has given
                  irrevocable instructions for transmission of the applicable
                  filing fee in connection with the filing of the Rule 462(b)
                  Registration Statement, in compliance with Rule 111
                  promulgated under the Act or the Commission has received
                  payment of such filing fee.

                           (iv)   Neither the Commission nor the "blue sky" or
                  securities authority of any jurisdiction have issued an order
                  (a "Stop Order") suspending the effectiveness of the
                  Registration Statement, preventing or suspending the use of
                  any Preliminary Prospectus, the Prospectus, the Registration
                  Statement, or any amendment or supplement thereto, refusing to
                  permit the effectiveness of the Registration Statement, or
                  suspending the registration or qualification of the Firm
                  Shares or the Option Shares nor has any of such authorities
                  instituted or threatened to institute any proceedings with
                  respect to a Stop Order.

                           (v)    Any contract, agreement, instrument, lease, or
                  license required to be described in the Registration Statement
                  or the Prospectus has been properly described therein. Any
                  contract agreement, instrument, lease, or license required to
                  be filed as an exhibit to the Registration Statement has been
                  filed with the Commission as an exhibit to or has been
                  incorporated as an exhibit by reference into the Registration
                  Statement.

                           (vi)   The Company is a corporation duly organized,
                  validly existing, and in good standing under the laws of the
                  State of California, with full corporate power and authority,
                  and all necessary consents, authorizations, approvals, orders,
                  licenses, certificates, and permits of and from, and
                  declarations and filings with, all federal, state, local, and
                  other governmental authorities and all courts and other
                  tribunals, to own, lease, license, and use its properties and
                  assets and to carry on its business as now being conducted and
                  in the manner described in the Prospectus. The Company is duly
                  qualified to do business and is in good standing in each
                  jurisdiction in which its ownership, leasing, licensing, or
                  character, location or use of property and assets or the
                  conduct of its business makes such qualification necessary.
                  The Company does not own, lease or license any property or
                  conduct any business outside the United States of America. The
                  Company has no subsidiary or subsidiaries and does not
                  control, directly or indirectly, any corporation, partnership,
                  joint venture,


                                       -5-

                  association or other business organization, except for those
                  permitted to be excluded pursuant to Item 601, Exhibit 21 of
                  Regulation S-K.

                           (vii)  The authorized capital stock of the Company
                  consists of 28,000,000 shares of Common Stock, of which [ ]
                  shares are outstanding, and 12,000,000 preferred shares of the
                  Company (the "Preferred Stock"), of which [ ] shares are
                  outstanding. Each outstanding share of Common Stock and
                  Preferred Stock has been duly and validly authorized and
                  issued, fully paid, and non-assessable, without any personal
                  liability attaching to the ownership thereof and has not been
                  issued and is not owned or held in violation of any preemptive
                  rights of shareholders. There is no commitment, plan,
                  preemptive right or arrangement to issue, and no outstanding
                  option, warrant, or other right calling for the issuance of,
                  shares of capital stock of the Company or any security or
                  other instrument which by its terms is convertible into,
                  exercisable for, or exchangeable for capital stock of the
                  Company, except as may be properly described in the
                  Prospectus. There is outstanding no security or other
                  instrument which by its terms is convertible into or
                  exchangeable for capital stock of the Company, except as may
                  be properly described in the Prospectus.

                           (viii) The financial statements of the Company
                  included in the Registration Statement and the Prospectus
                  fairly present, with respect to the Company the financial
                  position, the results of operations, and the other information
                  purported to be shown therein at the respective dates and for
                  the respective periods to which they apply. Such financial
                  statements have been prepared in accordance with generally
                  accepted accounting principles (except to the extent that
                  certain footnote disclosures regarding any stub period may
                  have been omitted in accordance with the applicable rules of
                  the Commission under the Securities Exchange Act of 1934, as
                  amended (the "Exchange Act")) consistently applied throughout
                  the periods involved, are correct and complete, and are in
                  accordance with the books and records of the Company. The
                  accountants whose report on the audited financial statements
                  is filed with the Commission as a part of the Registration
                  Statement are, and during the periods covered by their
                  report(s) included in the Registration Statement and the
                  Prospectus were, independent certified public accountants with
                  respect to the Company within the meaning of the Act and the
                  Regulations. No other financial statements are required by
                  Form S-1 or otherwise to be included in the Registration
                  Statement or the Prospectus. There has at no time been a
                  material adverse change in the financial condition, results of
                  operations, business, properties, assets, liabilities, or
                  future prospects of the Company from the latest information
                  set forth in the Registration Statement or the Prospectus,
                  except as may be properly described in the Prospectus.

                           (ix)   There is no litigation, arbitration, claim,
                  governmental or other proceeding (formal or informal), or
                  investigation before any court or before any public body or
                  board pending, threatened, or in prospect (or any basis
                  therefor) with

                  respect to the Company, or any of its operations, business,
                  properties, or assets, except as may be properly described in
                  the Prospectus or such as individually or in the aggregate do
                  not now have and will not in the future have a material
                  adverse effect upon the operations, business, properties,
                  assets or financial condition of the Company. The Company is
                  not involved in any labor dispute, nor is such dispute
                  threatened, which dispute would have a material adverse effect
                  upon the operations, business, properties, assets or financial
                  condition of the Company. The Company is not in violation of,
                  or in default with respect to, any law, rule, regulation,
                  order, judgment, or decree; nor is the Company required to
                  take any action in order to avoid any such violation or
                  default.

                           (x)    The Company has good and marketable title in
                  fee simple absolute to all real properties and good title to
                  all other properties and assets which the Prospectus indicates
                  are owned by it, and has valid and enforceable leasehold
                  interests in each of such items, free and clear of all liens,
                  security interests, pledges, charges, encumbrances, and
                  mortgages (except as may be properly described in the
                  Prospectus). No real property owned, leased, licensed or used
                  by the Company lies in an area which is, or to the knowledge
                  of the Company will be, subject to zoning, use or building
                  code restrictions which would prohibit, and no state of facts
                  relating to the actions or inaction of another person or
                  entity or his or its ownership, leasing, licensing or use of
                  any real or personal property exists or will exist which would
                  prevent, the continued effective ownership, leasing, licensing
                  or use of such real property in the business of the Company as
                  presently conducted or as the Prospectus indicates it
                  contemplates conducting (except as may be properly described
                  in the Prospectus).

                           (xi)   The Company, and to the knowledge of the
                  Company, any other party, is not now or is not expected by the
                  Company to be in violation or breach of, or in default with
                  respect to, complying with any term, obligation or provision
                  of any contract, agreement, instrument, lease, license,
                  indenture, mortgage, deed of trust, note, arrangement or
                  understanding which is material to the Company or by which any
                  of its properties or business may be bound or affected, and no
                  event has occurred which with notice or lapse of time or both
                  would constitute such a default, and each such contract,
                  agreement, instrument, lease, license, indenture, mortgage,
                  deed of trust, note, arrangement or understanding is in full
                  force and is the legal, valid and binding obligation of the
                  parties thereto and is enforceable as to them in accordance
                  with its terms. The Company enjoys peaceful and undisturbed
                  possession under all leases and licenses under which it is
                  operating. The Company is not a party to or bound by any
                  contract, agreement, instrument, lease, license, indenture,
                  mortgage, deed of trust, note, arrangement or understanding,
                  or subject to any charter or other restriction, which has had
                  or may in the future have a material adverse effect on the
                  financial condition, results of operations, business,
                  properties, assets, liabilities or future prospects of the
                  Company. The Company is not in violation or breach of, or in
                  default with respect to, any term of its


                                       -7-

                  certificate of incorporation (or other charter document) or
                  by-laws or of any franchise, license, permit, judgment,
                  decree, order, statute, rule or regulation.

                           (xii)  The Company has filed all federal, state, 
                  local and foreign tax returns which are required to be filed
                  through the date hereof, or have received extensions thereof,
                  and have paid all taxes shown on such returns and all
                  assessments received by it to the extent that the same are
                  material and have become due.

                           (xiii) All patents, patent applications, trademarks,
                  trademark applications, trade names, service marks,
                  copyrights, copyright applications, franchises, and other
                  intangible properties and assets listed in the Registration
                  Statement under "Business- Patents" (all of the foregoing
                  being collectively herein called "Intangibles") that the
                  Company owns, possesses or has pending, or under which it is
                  licensed, are in good standing and uncontested. There is no
                  right under any Intangible necessary to the business of the
                  Company as presently conducted or as the Prospectus indicates
                  the Company contemplates conducting (except as may be so
                  described in the Prospectus). The Company has not infringed,
                  is infringing, or has received any notice of infringement with
                  respect to asserted Intangibles of others. To the knowledge of
                  the Company, there is no infringement by others of Intangibles
                  of the Company. To the knowledge of the Company, there is no
                  Intangible of others which has had or may in the future have a
                  materially adverse effect on the financial condition, results
                  of operations, business, properties, assets, liabilities or
                  future prospects of the Company.

                           (xiv)  Neither the Company, any director, officer,
                  agent, employee or other person associated with or acting on
                  behalf of the Company has, directly or indirectly: used any
                  corporate funds for unlawful contributions, gifts,

                  violated any provision of the Foreign Corrupt Practices Act of
                  1977, as amended; or made any bribe, rebate, payoff, influence
                  payment, kickback, or other unlawful payment. No transaction
                  has occurred between or among the Company and any of its
                  officers or directors or any affiliates or affiliates of any
                  such officer or director, except as described in the
                  Prospectus.

                           (xv)   The Company has all requisite power and
                  authority to execute, deliver and perform each of this
                  Agreement and the Representative's Warrants (collectively, the

                           (xxii)  The Company has obtained from each of its
                  executive officers and directors and principal shareholders,
                  their enforceable written agreement, in form and substance
                  satisfactory to counsel for the Underwriters, that for a
                  period of 180 days from

                  the date on which the public offering of the Shares commences
                  they will not, without the prior written consent of Rodman, on
                  behalf of the Underwriters, offer, pledge, sell, contract to
                  sell, grant any option for the sale of, or otherwise dispose
                  of, directly or indirectly, any shares of Common Stock or
                  other securities of the Company (or any security or other
                  instrument which by its terms is convertible into, exercisable
                  for, or exchangeable for shares of Common Stock or other
                  securities of the Company, including, without limitation, any
                  shares of Common Stock issuable under any employee stock

                           (xxiii)  The Company is not, and does not intend to
                  conduct its business in a manner in which it would be, an
                  "investment company" as defined in Section 3(a) of the
                  Investment Company Act of 1940 (the "Investment Company Act").

                           (xxiv)   All offers and sales of the Company's 
                  capital stock prior to the date hereof, were at all relevant
                  times exempt from the registration requirements of the Act,
                  and were the subject of an available exemption from the
                  registration requirements of all applicable state securities
                  or blue sky laws.

                           (xxv)    No person or entity has the right to require
                  registration of shares of Common Stock or other securities of
                  the Company because of the filing or effectiveness of the
                  Registration Statement, except such person or entities from
                  whom written waivers of such rights have been received prior
                  to the date hereof.

                           (xxvi)   Except as may be set forth in the 
                  Prospectus, the Company has not incurred any liability for a
                  fee, commission or other compensation on account of the
                  employment of a broker or finder in connection with the
                  transactions contemplated by this Agreement.

                           (xxvii)  No transaction has occurred between or among
                  the Company and any of its officers or directors or any
                  affiliates of any such officer or director, that is required
                  to be described in and is not described in the Registration
                  Statement and the Prospectus.

                           (xxviii) The Common Stock, including the Shares, are
                  authorized for quotation on the Nasdaq National Market.

                           (xxix)   Neither the Company nor any of its 
                  affiliates is presently doing business with the government of
                  Cuba or with any person or affiliate located in Cuba. If, at
                  any time after the date that the Registration Statement is
                  declared effective with the Commission or with the Florida
                  Department of Banking and Finance (the "Florida Department"),
                  whichever date is later, and prior to the end of the period
                  referred to in the first clause of Section 4(ii) hereof, the
                  Company commences engaging in business with the government of
                  Cuba or with any person or affiliate located in Cuba, the
                  Company will so inform the Florida Department within ninety
                  days after such commencement of business in Cuba, and during
                  the


                                      -11-

                  Florida Department within ninety days after any change occurs
                  with respect to previously reported information.

         from Price Waterhouse, LLP addressed to the Representatives and dated,

         form and scope reasonably satisfactory to the Representatives, with
         reproduced copies or signed counterparts thereof for each of the
         Underwriters confirming that they are independent accountants within
         the meaning of the Act and the Regulations, that the response to Item
         10 of the Registration Statement is correct in so far as it relates to
         them and stating in effect that:

                          (i)       in its opinion the audited financial 
                  statements and financial statement schedules included or
                  incorporated by reference in the Registration Statement and
                  the Prospectus and reported on by it comply as to form in all
                  material respects with the applicable accounting requirements
                  of the Act, the Exchange Act and the related published rules
                  and regulations thereunder;

                          (ii)      on the basis of a reading of the amounts
                  included in the Registration Statement and the Prospectus
                  under the headings "Summary Financial Data" and "Selected
                  Financial Data" which would not necessarily reveal matters of
                  significance with respect to the comments set forth in such
                  letter, a reading of the minutes of the meetings of the
                  shareholders and directors of the Company, and inquiries of
                  certain officials of the Company who have responsibility for
                  financial and accounting matters of the Company as to
                  transactions and events subsequent to the date of the latest
                  audited financial statements, except as disclosed in the
                  Registration Statement and the Prospectus, nothing came to its
                  attention which caused it to believe that:

                                    (A) the amounts in "Summary Financial Data"
                           and "Selected Financial Data" included in the
                           Registration Statement and the Prospectus do not
                           agree with the corresponding amounts in the audited
                           financial statements from which such amounts were
                           derived; or

                           the shareholders' equity in the Company, as compared
                           with the amounts shown on the Company's audited
                           Balance Sheet for the fiscal year ended December 31,
                           1995 included in the Registration Statement or the
                           audited Statement of Operations, for such year; and

                           (iii)    it has performed certain other procedures as
                  a result of which it determined that information of an
                  accounting, financial or statistical nature (which is limited
                  to accounting, financial or statistical information derived
                  from the general accounting records of the Company) set forth
                  in the Registration Statement and the Prospectus and
                  reasonably specified by the Representatives agrees with the
                  accounting records of the Company.

         this paragraph (e) are to such documents as amended and supplemented at
         the date of such letter.

                  (f)      The Representatives shall have received on each 
         Closing Date from Luce, Forward, Hamilton & Scripps, counsel for the 
         Company, an opinion, addressed to the Representatives and dated such  
         Closing Date, and in form and scope satisfactory to counsel for the
         Underwriters, with reproduced copies or signed counterparts thereof for
         each of the Underwriters, to the effect that:

                           (i)      The Company is a corporation duly organized,
                  validly existing, and in good standing under the laws of the
                  State of Delaware, with full corporate power and authority to
                  own, lease, license and use its properties and assets and to
                  conduct its business in the manner described in the
                  Prospectus. To the knowledge of such counsel, the Company has
                  all necessary consents, authorizations, approvals, orders,
                  certificates and permits of and from, and declarations and
                  filings with, all federal, state, local and other governmental
                  authorities and all courts and other tribunals, to own, lease,
                  license and use its properties and assets and to conduct its
                  business in the manner described in the Prospectus. The
                  Company is duly qualified to do business and is in good
                  standing, in each state where the failure to be so qualified
                  could have a material adverse effect on the operating
                  condition (financial and otherwise) or business of the
                  Company. The Company does not own, lease or license any
                  property or conduct any business outside the United States of
                  America. The Company has no subsidiary or subsidiaries and
                  does not control, directly or indirectly, any corporation,
                  partnership, joint venture, association or other business
                  organization, except for those permitted to be excluded
                  pursuant to Item 601, Exhibit 21 of Regulation S-K.

                           (ii)     The Company has authorized, issued and
                  outstanding capital stock as set forth in the "actual" column
                  of the capitalization table under the caption "Capitalization"
                  in the Prospectus. The certificates evidencing the Shares are
                  in due and proper legal form. Each outstanding share of Common
                  Stock and Preferred Stock has been duly and validly authorized
                  and issued, fully paid, and non-assessable, without any
                  personal liability attaching to the ownership thereof, and has
                  not been issued and is not owned or held in violation of any
                  preemptive right of shareholders. To the knowledge of such
                  counsel, there is no commitment, plan, or arrangement to
                  issue, and no outstanding option, warrant, or other right
                  calling for the issuance of, any share of capital stock of the
                  Company or any security or other instrument which by its terms
                  is convertible into, exercisable for, or exchangeable for
                  capital stock of the Company, except as may be properly
                  described in the Prospectus. To the knowledge of such counsel,
                  there is outstanding no security or other instrument which by
                  its terms is convertible into, exercisable for or exchangeable
                  for capital stock of the Company, except as may be properly
                  described in the Prospectus.

                           (iii)    To the knowledge of such counsel, there is 
                  no litigation, arbitration, claim, governmental or other
                  proceeding (formal or informal), or investigation before any
                  court or before any public body or board pending, threatened,
                  or in prospect (or any basis therefor) with respect to the
                  Company, or any of its operations, businesses, properties,
                  assets, or financial condition except as may be properly
                  described in the Prospectus or such as individually or in the
                  aggregate do not now have and will not in the future have a
                  material adverse effect upon the operations, business,
                  properties, assets, or financial condition of the Company. To
                  the knowledge of such counsel, the Company is not involved in
                  any labor dispute, nor is such dispute threatened, which
                  dispute would have a material adverse effect upon the
                  operations, business, properties, assets or financial
                  condition of the Company. The Company is not in violation of,
                  or in default with respect to, any law, rule, regulation,
                  order, judgment, or decree, except as may be properly
                  described in the Prospectus or such as in the aggregate do not
                  now have and will not in the future have a material adverse
                  effect upon the operations, business, properties, assets, or
                  financial condition of the Company; nor is the Company
                  required to take any action in order to avoid any such
                  violation or default.

                           (iv)     To the knowledge of such counsel, the 
                  Company, nor any other party is now or is expected by the
                  Company to be in violation or breach of, or in default with
                  respect to, complying with any term, obligation or provision
                  of any contract, agreement, instrument, lease, license,
                  indenture, mortgage, deed of trust, note, arrangement or
                  understanding which is material to the Company or by which any
                  of its properties or businesses may be bound or affected and
                  no event has occurred which with notice or lapse of time or
                  both would constitute such a default.

                           (v)      The Company is not in violation or breach 
                  of, or in default with respect to, any term of its certificate
                  of incorporation (or other charter document) or by-laws.

                           (vi)     The Company has all requisite power and
                  authority to execute, deliver and perform this Agreement, to
                  issue and sell the Shares and to issue the Representative's
                  Warrants. All necessary corporate proceedings of the Company
                  have been taken to authorize the execution, delivery and
                  performance by the Company of the Company Documents. Each of
                  the Company Documents has been duly authorized, executed and
                  delivered by the Company, is the legal, valid and binding
                  obligation of the Company and (subject to applicable
                  bankruptcy, insolvency, and other laws affecting the
                  enforceability of creditors' rights generally) is enforceable

                  of its properties or assets are subject, is required for the
                  execution, delivery or performance of the Company Documents;
                  and the execution, delivery and performance of the Company
                  Documents will not violate, result in a breach of, conflict
                  with, or (with or without the giving of notice or the passage
                  of time or both) entitle any party to terminate or call a
                  default under any such contract, agreement, instrument, lease,

                  violate or result in a breach of any term of the certificate
                  of incorporation (or other charter document) or by-laws of the
                  Company, or violate, result in a breach of, or conflict with
                  any law, rule, regulation, order, judgment, or decree binding
                  on the Company or to which any of its operations, businesses,
                  properties or assets are subject.

                           (vii)    The Firm Shares and the Option Shares are 
                  duly and validly authorized. Such opinion delivered at each of
                  the Closing Dates shall state that each Share, as the case may
                  be, to be delivered on that date is duly and validly issued,
                  fully paid, and non-assessable, with no personal liability
                  attaching to the ownership thereof, and is not issued in
                  violation of any preemptive rights of shareholders, and the
                  Underwriters have received good title to the Shares purchased
                  by them, respectively, from the Company for the consideration
                  contemplated herein and in good faith and without notice of
                  any adverse claim within the meaning of the Uniform Commercial
                  Code, free and clear of any liens, security interests,
                  pledges, charges, encumbrances, shareholders' agreements,
                  voting trusts and other claims. The Common Stock, the
                  Preferred Stock, the Firm Shares and the Option Shares conform
                  to all statements relating thereto contained in the
                  Registration Statement or the Prospectus.

                           (viii)   The Representative's Warrants have been duly
                  and validly authorized for issuance. Such opinion delivered at
                  the Firm Shares Closing Date shall state that the
                  Representative's Warrants to be delivered on that date have
                  been duly and validly issued, fully paid, and non-assessable,
                  with no personal liability attaching to the ownership thereof,
                  and will not have been issued in violation of any preemptive
                  rights of shareholders, optionholders, warrantholders and any
                  other persons, and the holders of the Representative's
                  Warrants will receive good title to the securities purchased
                  by them, respectively, from the Company, for the consideration
                  contemplated herein and in good faith and without notice of
                  any adverse claim within the meaning of the Uniform Commercial
                  Code, free and clear of any liens, security interests,
                  pledges, charges, encumbrances, shareholders' agreements,
                  voting trusts and other claims. The Representative's Warrants
                  conform to all statements relating thereto contained in the

                           (ix)     The Warrant Stock is duly and validly 
                  authorized and reserved for issuance and, when issued and
                  delivered upon exercise of the Representative's Warrants, will
                  be duly and validly issued, fully paid and non-assessable,
                  without any personal liability attaching to the ownership
                  thereof, and will not be issued in violation of any preemptive
                  rights of shareholders, optionholders, warrantholders and any
                  other persons and the holders of the Representative's Warrants
                  will receive good title to the securities purchased by them,
                  respectively, from the Company, for the consideration
                  contemplated herein and in good faith and without notice of
                  any adverse claim within the meaning of the Uniform Commercial
                  Code, free and clear of all liens, security interests,
                  pledges, charges, encumbrances, shareholders' agreements and
                  voting trusts and other claims. The Warrant Stock conforms to
                  all statements relating thereto contained in the Registration
                  Statement or the Prospectus.

                           (x)      All offers and sales of the Company's 
                  capital stock prior to the date hereof, were at all relevant
                  times exempt from the registration requirements of the Act,
                  and were the subject of an available exemption from the
                  registration requirements of all applicable state securities
                  or blue sky laws.

                           (xi)     To the knowledge of such counsel, any 
                  contract, agreement, instrument, lease or license required to
                  be described in the Registration Statement or the Prospectus
                  has been properly described therein. To the knowledge of such
                  counsel, any contract, agreement, instrument, lease or license
                  required to be filed as an exhibit to the Registration
                  Statement has been filed with the Commission as an exhibit to
                  or has been incorporated as an exhibit by reference into the
                  Registration Statement.

                           (xii)    Insofar as statements in the Prospectus 
                  purport to summarize the status of litigation or the
                  provisions of laws, rules, regulations, orders, judgments,
                  decrees, contracts, agreements, instruments, leases or
                  licenses, such statements have been prepared or reviewed by
                  such counsel and to the knowledge of such counsel, accurately
                  reflect the status of such litigation and provisions purported
                  to be summarized and are correct in all material respects.

                           (xiii)   The Company is not an "investment company" 
                  as defined in Section 3(a) of the Investment Company Act and,
                  if the Company conducts its business as set forth in the
                  Prospectus, will not become an "investment company" and will
                  not be required to be registered under the Investment Company
                  Act.

                           (xiv)    To the knowledge of such counsel, no person 
                  or entity has the right to require registration of shares of
                  Common Stock or other securities of the Company because of the
                  filing or effectiveness of the Registration Statement except
                  such persons or entities from whom written waivers of such
                  rights have been received prior to the Closing Date.

<PAGE>   18
                           (xv)     The Registration Statement has become 
                  effective under the Act. No Stop Order has been issued and no
                  proceedings for that purpose has been instituted or are
                  threatened, pending, or to such counsel's knowledge,
                  contemplated.

                           (xvi)    The Registration Statement, any Rule 430A
                  Prospectus, and the Prospectus, and any amendment or
                  supplement thereto (other than financial statements and other
                  financial data and schedules which are or should be contained
                  in any thereof, as to which such counsel need express no
                  opinion), comply as to form in all material respects with the
                  requirements of the Act and the Regulations. The conditions
                  for the use of Form S-1 have been satisfied with respect to
                  the Registration Statement.

                           (xvii)   Such counsel has no reason to believe that 
                  any of the Registration Statement, any Rule 430A Prospectus,
                  or the Prospectus, or any amendment or supplement thereto
                  (other than financial statements and other financial data and
                  schedules which are or should be contained in any thereof, as
                  to which such counsel need express no opinion), contains any
                  untrue statement of a material fact or omits to state a
                  material fact required to be stated therein or necessary to
                  make the statements therein not misleading.

                           (xviii)  To the knowledge of such counsel, since the
                  effective date of the Registration Statement, no event has
                  occurred which should have been set forth in an amendment or
                  supplement to the Registration Statement or the Prospectus
                  which has not been set forth in such an amendment or
                  supplement.

                           (xix)    The agreement of each officer, director and
                  principal shareholder of the Company, stating that for a
                  period of 180 days from the date on which the public offering
                  of the Shares commences, such officer, director and principal
                  shareholder will not, without the prior written consent of
                  Rodman, on behalf of the Underwriters, offer, pledge, sell,
                  contract to sell, grant any option for the sale of, or
                  otherwise dispose of, directly or indirectly, any shares of
                  Common Stock (or any other securities of the Company or any
                  security or other instrument which by its terms is convertible
                  into, exercisable for, or exchangeable for shares of Common
                  Stock or other securities of the Company, including, without
                  limitation, any shares of Common Stock issuable under any
                  employee stock options), beneficially owned by such
                  individual, has been duly and validly authorized, executed and
                  delivered by such individual and constitutes the legal, valid
                  and binding obligation of such individual enforceable against
                  such individual in accordance with its terms.

                  In addition, such counsel shall state that such counsel has
participated in the preparation of the Registration Statement and the Prospectus
and in conferences with officers and other representatives of the Company,
representatives of the Representatives and representatives of the independent
accountants of the Company, at which conferences the contents of the
Registration Statement and the Prospectus and related matters were discussed


                                      -18-
<PAGE>   19
and, although such counsel has not independently verified and is not passing
upon and does not assume any responsibility for the accuracy, completeness or
fairness of the statements contained in the Registration Statement and the
Prospectus (except as specified in the foregoing opinion), on the basis of the
foregoing and relying as to materiality upon the representations of executive
officers of the Company after conferring with such executive officers, no facts
have come to the attention of such counsel which lead such counsel to believe
that the Registration Statement at the time it became effective contained any
untrue statement of a material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or that the Prospectus, except for the financial statements and other financial
and statistical data included therein as to which counsel need express no
opinion, as amended or supplemented on the date thereof contained any untrue
statement of a material fact or omitted to state a material fact necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading.

                  In rendering their opinion as aforesaid, counsel may rely upon
an opinion or opinions, each dated the Closing Date, of other counsel retained
by the Company as to laws of any jurisdiction other than the Federal laws of the
United States, the General Corporate Law of the states of Delaware and New York,
provided that (1) each such local counsel is reasonably acceptable to the
Representatives and (2) such reliance is expressly authorized by each opinion so
relied upon and a copy of each such opinion is addressed to the Representatives
and is in form and substance reasonably satisfactory to them and their counsel.
In addition, such counsel may rely, as to matters of fact, to the extent such
counsel deems proper, on certificates of responsible officers of the Company,
provided that executed copies of such certificates are provided to the
Representatives.

                  (g)    The Representatives shall have received on each Closing
         Date from [Luce, Forward, Hamilton & Scripps], patent counsel for the
         Company, an opinion, addressed to the Representatives and dated such
         Closing Date, and in form and scope satisfactory to counsel for the
         Representatives with respect to such patent matters as the
         Representatives may reasonably require.

                  (h)    The Representatives shall have received on each Closing
         Date from [    ], special regulatory counsel for the Company, an 
         opinion, addressed to the Representatives and dated such Closing Date,
         and in form and scope satisfactory to counsel for the Representatives 
         with respect to such regulatory and compliance matters as the
         Representatives may reasonably require.

                  (i)    All proceedings taken in connection with the sale of 
         the Firm Shares and the Option Shares as herein contemplated shall be
         satisfactory in form and substance to the Representatives and its
         counsel, and the Underwriters shall have received from Squadron,
         Ellenoff, Plesent & Sheinfeld, LLP, a favorable opinion, addressed to
         the Representatives and dated such Closing Date, with respect to the
         Shares, the Registration Statement and the Prospectus, and such other
         related matters, as the Representatives may reasonably request, and the
         Company shall have furnished to Squadron, Ellenoff, Plesent &
         Sheinfeld, LLP, such documents


                                      -19-
<PAGE>   20
         as they may reasonably request for the purpose of enabling them to pass
         upon such matters.

                  (j)      On the Firm Shares Closing Date, the Company shall 
         have issued to Rodman, the Representative's Warrants equal to 10% of
         the shares of Common Stock sold on the Firm Shares Closing Date.

         6.       Covenants of the Company.

                  (a)      The Company covenants and agrees as follows:

                           (i)      The Company shall use its best efforts to 
                  cause the Registration Statement to become effective as
                  promptly as possible. If the Registration Statement has become
                  or becomes effective with a form of prospectus omitting Rule
                  430A information, or filing of the Prospectus is otherwise
                  required under Rule 424(b), the Company will file the
                  Prospectus, properly completed, pursuant to Rule 424(b) within
                  the time period prescribed and will provide evidence
                  satisfactory to you of such timely filing. The Company shall
                  notify you immediately, and confirm such notice in writing,
                  (A) when the Registration Statement and any post-effective
                  amendment thereto become effective, (B) of the receipt of any
                  comments from the Commission or the "blue sky" or securities
                  authority of any jurisdiction regarding the Registration
                  Statement, any post-effective amendment thereto, the
                  Prospectus, or any amendment or supplement thereto, and (C) of
                  the receipt of any notification with respect to a Stop Order.
                  The Company shall not file any amendment of the Registration
                  Statement or supplement to the Prospectus unless the Company
                  has furnished the Representatives a copy for their review
                  prior to filing and shall not file any such proposed amendment
                  or supplement to which the Representatives reasonably object.
                  The Company shall use its best efforts to prevent the issuance
                  of any Stop Order and, if issued, to obtain as soon as
                  possible the withdrawal thereof.

                           (ii)     During the time when a Prospectus relating 
                  to the Shares is required to be delivered hereunder or under
                  the Act or the Regulations, comply so far as it is able with
                  all requirements imposed upon it by the Act, as now existing
                  and as hereafter amended, and by the Regulations, as from time
                  to time in force, so far as necessary to permit the
                  continuance of sales of or dealings in the Shares in
                  accordance with the provisions hereof and the Prospectus. If,
                  at any time when a prospectus relating to the Shares is
                  required to be delivered under the Act and the Regulations,
                  any event as a result of which the Prospectus as then amended
                  or supplemented would include any untrue statement of a
                  material fact or omit to state any material fact necessary to
                  make the statements therein in the light of the circumstances
                  under which they were made not misleading, or if it shall be
                  necessary to amend or supplement the Prospectus to comply with
                  the Act or the Regulations, the Company promptly shall prepare
                  and file with the Commission, subject to the third sentence of
                  paragraph (i) of this Section 6(a), an amendment or supplement
                  which shall correct such


                                      -20-
<PAGE>   21
                  statement or omission or an amendment which shall effect such
                  compliance.

                           (iii)    The Company shall make generally available 
                  to its security holders and to the Representatives as soon as
                  practicable, but not later than 45 days after the end of the
                  12-month period beginning at the end of the fiscal quarter of
                  the Company during which the Effective Date (or 90 days if
                  such 12-month period coincides with the Company's fiscal
                  year), an earnings statement (which need not be audited) of
                  the Company, covering such 12-month period, which shall
                  satisfy the provisions of Section 11(a) of the Act or Rule 158
                  of the Regulations.

                           (iv)     The Company shall furnish to the 
                  Representatives and counsel for the Underwriters, without
                  charge, signed copies of the Registration Statement (including
                  all exhibits and amendments thereto) and to each other
                  Underwriter a copy of the Registration Statement (without
                  exhibits thereto) and all amendments thereof and, so long as
                  delivery of a prospectus by an Underwriter or dealer may be
                  required by the Act or the Regulations, as many copies of any
                  preliminary prospectus and the Prospectus and any amendments
                  thereof and supplements thereto as the Representatives may
                  reasonably request.

                           (v)      The Company shall cooperate with the
                  Representatives and its counsel in endeavoring to qualify the
                  Shares for offer and sale under the laws of such jurisdictions
                  as the Representatives may designate and shall maintain such
                  qualifications in effect so long as required for the
                  distribution of the Shares; provided, however, that the
                  Company shall not be required in connection therewith, as a
                  condition thereof, to qualify as a foreign corporation or to
                  execute a general consent to service of process in any
                  jurisdiction or subject itself to taxation as doing business
                  in any jurisdiction.

                           (vi)     For a period of five years after the date of
                  this Agreement, the Company shall supply to the
                  Representatives, and to each other Underwriter who may so
                  request in writing, copies of such financial statements and
                  other periodic and special reports as the Company may from
                  time to time distribute generally to the holders of any class
                  of its capital stock and to furnish to the Representatives a
                  copy of each annual or other report it shall be required to
                  file with the Commission.

                           (vii)    Without the prior written consent of Rodman,
                  on behalf of the Underwriters, for a period of 180 days from
                  the date on which a public offering of the Shares commences,
                  the Company shall not issue, sell or register with the
                  Commission or otherwise dispose of, directly or indirectly,
                  any securities of the Company (or any securities convertible
                  into or exercisable or exchangeable for securities of the
                  Company), except for the issuance of the Shares pursuant to
                  the Registration Statement.

                           (viii)   If the Company elects to rely on Rule 
                  462(b), the Company shall both file a Rule 462(b) Registration
                  Statement with the Commission in compliance with Rule 462(b)
                  and pay the applicable fees in accordance with Rule 111
                  promulgated under the Act by the earlier of (i) 10:00 p.m.
                  eastern time on the date of this Agreement and (ii) the time
                  confirmations are sent or given, as specified by Rule
                  462(b)(2).

                           (ix)     On or before completion of this offering, 
                  the Company shall make all filings required under applicable
                  securities laws and by the Nasdaq National Market.

                           (x)      Prior to each Closing Date and for a period 
                  of 25 days thereafter, you shall be given reasonable written
                  prior notice of any press release or other direct or indirect
                  communication and of any press conference with respect to the
                  Company, the financial conditions, results of operations,
                  business, properties, assets, liabilities of the Company, or
                  this offering.

                           (xi)     Until expiration of the Representative's
                  Warrants, the Company shall keep reserved sufficient shares of
                  Common Stock for issuance upon exercise thereof.

                           (xii)    The Company shall use its reasonable efforts
                  to assure that the restrictions set forth in the so-called
                  "lock-up" agreements signed by certain shareholders of the
                  Company are enforced.

                           (xiii)   The Company will make all filings required 
                  to be made under the Exchange Act and such filings shall
                  comply in all material respects with the requirements of the
                  Exchange Act and the rules and regulations thereunder.

                           (xiv)    For a period of one year after the Firm 
                  Shares Closing Date, the Company shall grant Rodman,
                  individually and not as representative of the Underwriters, a
                  30-day right of first negotiation to act as the Company's
                  financial advisor or managing underwriter or exclusive
                  placement agent, as the case may be, in connection with any
                  sale of the Company (including the sale of a majority or
                  controlling minority interest in the stock or assets of the
                  Company), an acquisition or merger by the Company, or the
                  raising of additional financing through either a public or
                  private offering of securities.

                  (b)      The Company agrees to pay, or reimburse if paid by 
         the Representatives, whether or not the transactions contemplated 
         hereby are consummated or this Agreement is terminated, all costs and 
         expenses relating to the registration and public offering of the Shares
         including those relating to: (i) the preparation, printing, filing and
         distribution of the Registration Statement including all exhibits
         thereto, each preliminary prospectus, the Prospectus, all amendments
         and supplements to the Registration Statement and the Prospectus, and
         any documents required to be delivered with any Preliminary Prospectus
         or the Prospectus, and the printing, filing and distribution of the
         Agreement Among


                                      -22-
<PAGE>   23
         Underwriters, this Agreement and related documents; (ii) the
         preparation and delivery of certificates for the Shares to the
         Underwriters; (iii) the registration or qualification of the Shares for
         offer and sale under the securities or Blue Sky laws of the various
         jurisdictions referred to in Section 6(a)(v), including the fees and
         disbursements of counsel for the Underwriters in connection with such
         registration and qualification and the preparation, printing,
         distribution and shipment of preliminary and supplementary Blue Sky
         memoranda; (iv) the furnishing (including costs of shipping and
         mailing) to the Representatives and to the Underwriters of copies of
         each preliminary prospectus, the Prospectus and all amendments or
         supplements to the Prospectus, and of the several documents required by
         this Section to be so furnished, as may be reasonably requested for use
         in connection with the offering and sale of the Shares by the
         Underwriters or by dealers to whom Shares may be sold; (v) the filing
         fees of the National Association of Securities Dealers, Inc. in
         connection with its review of the terms of the public offering; (vi)
         the furnishing (including costs of shipping and mailing) to the
         Representatives and to the Underwriters of copies of all reports and
         information required by Section 6(a)(vi); (vii) inclusion of the Shares
         for quotation on the Nasdaq National Market; and (viii) all transfer
         taxes, if any, with respect to the sale and delivery of the Shares by
         the Company to the Underwriters. Except as otherwise contemplated by
         Section 9 hereof, the Underwriters will pay their own counsel fees and
         expenses to the extent not otherwise covered by clause (iii) above, and
         their own travel and travel-related expenses in connection with the
         distribution of the Shares. Without limiting the Company's obligations
         set forth above, it agrees to pay all of its other costs and expenses
         incident to the performance of its obligations under this Agreement and
         the sale of the Shares by it hereunder.

         7.       Indemnification.

                  (a)     The Company agrees to indemnify and hold harmless each
         Underwriter and each person, if any, who controls any Underwriter
         within the meaning of Section 15 of the Act or Section 20 of the
         Exchange Act against any and all losses, claims, damages and
         liabilities, joint or several (including any reasonable investigation,
         legal and other expenses incurred in connection with, and any amount
         paid in settlement of, any action, suit or proceeding or any claim
         asserted), to which they, or any of them, may become subject under the
         Act, the Exchange Act or other Federal or state law or regulation, at
         common law or otherwise, insofar as such losses, claims, damages or
         liabilities arise out of or are based upon any untrue statement or
         alleged untrue statement of a material fact contained in any
         preliminary prospectus, the Registration Statement or the Prospectus or
         any amendment thereof or supplement thereto, or arise out of or are
         based upon any omission or alleged omission to state therein such fact
         required to be stated therein or necessary to make such statements
         therein not misleading. Such indemnity shall not inure to the benefit
         of any Underwriter (or any person controlling such Underwriter) on
         account of any losses, claims, damages or liabilities arising from the
         sale of the Shares to any person by such Underwriter if such untrue
         statement or omission or alleged untrue statement or omission was made
         in such preliminary prospectus, the Registration Statement or the
         Prospectus, or such amendment or supplement, in reliance upon and in


                                      -23-
<PAGE>   24
         conformity with information furnished in writing to the Company by the
         Representatives on behalf of any Underwriter specifically for use
         therein. In no event shall the indemnification agreement contained in
         this Section 7(a) inure to the benefit of any Underwriter on account of
         any losses, claims, damages, liabilities or actions arising from the
         sale of the Shares upon the public offering to any person by such
         Underwriter if such losses, claims, damages, liabilities or actions
         arise out of, or are based upon, a statement or omission or alleged
         omission in a preliminary prospectus and if, in respect to such
         statement, omission or alleged omission, the Prospectus differs in a
         material respect from such preliminary prospectus, such that the
         Prospectus does not contain such untrue statement or such omission or
         alleged untrue statement or omission, and a copy of the Prospectus has
         not been sent or given to such person at or prior to the confirmation
         of such sale to such person. This indemnity agreement will be in
         addition to any liability which the Company may otherwise have.

                  (b)     Each Underwriter agrees, severally and not jointly, to
         indemnify and hold harmless the Company, each person, if any, who
         controls the Company within the meaning of Section 15 of the Act or
         Section 20 of the Exchange Act, each director of the Company, and each
         officer of the Company who signs the Registration Statement, to the
         same extent as the foregoing indemnity from the Company to each
         Underwriter, but only insofar as such losses, claims, damages or
         liabilities arise out of or are based upon any untrue statement or
         omission or alleged untrue statement or omission which was made in any
         Preliminary Prospectus, any Rule 430A Prospectus, the Registration
         Statement or the Prospectus, or any amendment thereof or supplement
         thereto, which were made in reliance upon and in conformity with
         information furnished in writing to the Company by the Representatives
         on behalf of any Underwriter for specific use therein; provided,
         however, that the obligation of each Underwriter to indemnify the
         Company (including any controlling person, director or officer thereof)
         shall be limited to the net proceeds received by the Company from such
         Underwriter. For all purposes of this Agreement, the amounts of the
         selling concession and reallowance set forth in the Prospectus
         constitute the only information furnished in writing by or on behalf of
         any Underwriter expressly for inclusion in any Preliminary Prospectus,
         any Rule 430A Prospectus, the Registration Statement or the Prospectus
         or any amendment or supplement thereto.

                  (c)     Any party that proposes to assert the right to be
         indemnified under this Section will, promptly after receipt of notice
         of commencement of any action, suit or proceeding against such party in
         respect of which a claim is to be made against an indemnifying party or
         parties under this Section , notify each such indemnifying party of the
         commencement of such action, suit or proceeding, enclosing a copy of
         all papers served. No indemnification provided for in Section 7(a) or
         7(b) shall be available to any party who shall fail to give notice as
         provided in this Section 7(c) if the party to whom notice was not given
         was unaware of the proceeding to which such notice would have related
         and was prejudiced by the failure to give such notice but the omission
         so to notify such indemnifying party of any such action, suit or
         proceeding shall not relieve it from any liability that it may have to
         any indemnified party for contribution or otherwise than under this
         Section . In case any such


                                      -24-
<PAGE>   25

         action, suit or proceeding shall be brought against any indemnified
         party and it shall notify the indemnifying party of the commencement
         thereof, the indemnifying party shall be entitled to participate in,
         and, to the extent that it shall wish, jointly with any other
         indemnifying party similarly notified, to assume the defense thereof,
         with counsel reasonably satisfactory to such indemnified party, and
         after notice from the indemnifying party to such indemnified party of
         its election so to assume the defense thereof and the approval by the
         indemnified party of such counsel, the indemnifying party shall not be
         liable to such indemnified party for any legal or other expenses,
         except as provided below and except for the reasonable costs of
         investigation subsequently incurred by such indemnified party in
         connection with the defense thereof. The indemnified party shall have
         the right to employ its counsel in any such action, but the fees and
         expenses of such counsel shall be at the expense of such indemnified
         party unless (i) the employment of counsel by such indemnified party
         has been authorized in writing by the indemnifying parties, (ii) the
         indemnified party shall have reasonably concluded that there may be a
         conflict of interest between the indemnifying parties and the
         indemnified party in the conduct of the defense of such action (in
         which case the indemnifying parties shall not have the right to direct
         the defense of such action on behalf of the indemnified party), or
         (iii) the indemnifying parties shall not have employed counsel to
         assume the defense of such action within a reasonable time after notice
         of the commencement thereof, in each of which cases the reasonable fees
         and expenses of counsel shall be at the expense of the indemnifying
         parties. An indemnifying party shall not be liable for any settlement
         of any action, suit, proceeding or claim effected without its written
         consent.

         8.       Contribution. In order to provide for just and equitable
contribution in circumstances in which the indemnification provided for in
Sections 7(a) and (b) is due in accordance with its terms but for any reason is
held to be unavailable from the Company or the Underwriters, the Company and the
Underwriters shall contribute to the aggregate losses, claims, damages and
liabilities (including any investigation, legal and other expenses reasonably
incurred in connection with, and any amount paid in settlement of, any action,
suit or proceeding or any claims asserted, but after deducting any contribution
received by the Company from persons other than the Underwriters, such as
persons who control the Company within the meaning of the Act, officers of the
Company who signed the Registration Statement and directors of the Company, who
may also be liable for contribution) to which the Company and one or more of the
Underwriters may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Company on the one hand and the Underwriters
on the other from the offering of the Shares or, if such allocation is not
permitted by applicable law or indemnification is not available as a result of
the indemnifying party not having received notice as provided in Section 7
hereof, in such proportion as is appropriate to reflect not only the relative
benefits referred to above but also the relative fault of the Company on the one
hand and the Underwriters on the other in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations. The relative
benefits received by the Company and the Underwriters shall be deemed to be in
the same proportion as (x) the total proceeds from the Offering (net of
underwriting discounts but before deducting expenses) received by the Company


                                      -25-
<PAGE>   26
from the sale of the Shares, as set forth in the table on the cover page of the
Prospectus (but not taking into account the use of the proceeds of such sale of
Shares by the Company), bear to (y) the underwriting discount received by the
Underwriters, as set forth in the table on the cover page of the Prospectus. The
relative fault of the Company and the Underwriters shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact related to information supplied by the Company or the
Underwriters and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission. The Company
and the Underwriters agree that it would not be just and equitable if
contribution pursuant to this Section 8 were determined by pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method of allocation which does not take account of the equitable
considerations referred to above. Notwithstanding the provisions of this 
Section 8, (i) in no case shall any Underwriter (except as may be provided in 
the Agreement Among Underwriters) be liable or responsible for any amount in 
excess of the underwriting discount applicable to the Shares purchased by such
Underwriter hereunder and (ii) the Company shall be liable and responsible for
any amount in excess of the underwriting discount; provided, however (i) that no
person guilty of fraudulent misrepresentation (within the meaning of Section 
11(f) of the Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 8,
each person, if any, who controls an Underwriter within the meaning of Section 
15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to
contribution as such Underwriter, and each person, if any, who controls the
Company within the meaning of the Section 15 of the Act or Section 20(a) of the
Exchange Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to clauses (i) and (ii) in the
immediately preceding sentence of this Section 8. Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties under this Section ,
notify such party or parties from whom contribution may be sought, but the
omission so to notify such party or parties from whom contribution may be sought
shall not relieve the party or parties from whom contribution may be sought from
any other obligation it or they may have hereunder or otherwise than under this
Section . No party shall be liable for contribution with respect to any action,
suit, proceeding or claim settled without its written consent. The Underwriters'
obligations to contribute pursuant to this Section 8 are several in proportion
to their respective underwriting commitments and not joint.

         9.       Termination.  This Agreement may be terminated with respect to
the Shares to be purchased on any Closing Date by the Representatives by 
notifying the Company at any time prior to the purchase of the Shares:

                  (a)     in the absolute discretion of the Representatives at 
         or before any Closing Date: (i) if on or prior to such date, any
         domestic or international event or act or occurrence has materially
         disrupted, or in the opinion of the Representatives will in the future
         materially disrupt, the securities markets; (ii) if there has occurred
         any new outbreak or material escalation of hostilities or other
         calamity or crisis the effect of which on the financial markets of the
         United States is such as to make it, in the judgment of the
         Representatives, inadvisable to proceed with

                                                      
                                      -26-
<PAGE>   27
         the Offering; (iii) if there shall be such a material adverse change in
         general financial, political or economic conditions or the effect of
         international conditions on the financial markets in the United States
         such as to make it, in the judgment of the Representatives, inadvisable
         or impracticable to market the Shares; (iv) if trading in the Shares
         has been suspended by the Commission or trading generally on the New
         York Stock Exchange, Inc., the American Stock Exchange, Inc. or the
         Nasdaq National Market has been suspended or limited, or minimum or
         maximum ranges for prices for securities shall have been fixed, or
         maximum ranges for prices for securities have been required, by said
         exchanges or by order of the Commission, the National Association of
         Securities Dealers, Inc., or any other governmental or regulatory
         authority; or (v) if a banking moratorium has been declared by any
         state or federal authority, or

                  (b)    at or before any Closing Date, if any of the conditions
         specified in Section 5 shall not have been fulfilled when and as
         required by this Agreement.

         If this Agreement is terminated pursuant to any of its provisions, the
Company shall not be under any liability to any Underwriter, and no Underwriter
shall be under any liability to the Company, except that (y) if this Agreement
is terminated by the Representatives or the Underwriters because of any failure,
refusal or inability on the part of the Company or all of them to comply with
the terms or to fulfill any of the conditions of this Agreement, the Company
will reimburse the Underwriters for all out-of-pocket expenses (including the
fees and disbursements of their counsel) incurred by them in connection with the
proposed purchase and sale of the Shares or in contemplation of performing their
obligations hereunder and (z) no Underwriter who shall have failed or refused to
purchase the Shares agreed to be purchased by it under this Agreement, without
some reason sufficient hereunder to justify cancellation or termination of its
obligations under this Agreement, shall be relieved of liability to the Company
or to the other Underwriters for damages occasioned by its failure or refusal.

         10.      Substitution of Underwriters. If one or more of the 
Underwriters shall fail (other than for a reason sufficient to justify the
cancellation or termination of this Agreement under Section 9) to purchase on
any Closing Date the Shares agreed to be purchased on such Closing Date by such
Underwriter or Underwriters, the Representatives may find one or more substitute
underwriters to purchase such Shares or make such other arrangements as the
Representatives may deem advisable or one or more of the remaining Underwriters
may agree to purchase such Shares in such proportions as may be approved by the
Representatives, in each case upon the terms set forth in this Agreement. If no
such arrangements have been made by the close of business on the business day
following such Closing Date:

                  (a)    if the number of Shares to be purchased by the 
         defaulting Underwriters on such Closing Date shall not exceed 10% of
         the Shares that all the Underwriters are obligated to purchase on such
         Closing Date, then each of the nondefaulting Underwriters shall be
         obligated to purchase such Shares on the terms herein set forth in
         proportion to their respective obligations hereunder; provided, that in
         no event shall the maximum number of Shares that any Underwriter has
         agreed to purchase


                                      -27-
<PAGE>   28
         pursuant to Section 1 be increased pursuant to this Section 10 by more
         than one-ninth of such number of Shares without the written consent of
         such Underwriter, or

                  (b)    if the number of Shares to be purchased by the 
         defaulting Underwriters on such Closing Date shall exceed 10% of the
         Shares that all the Underwriters are obligated to purchase on such
         Closing Date, then the Company shall be entitled to an additional
         business day within which it may, but is not obligated to, find one or
         more substitute underwriters reasonably satisfactory to the
         Representatives to purchase such Shares upon the terms set forth in
         this Agreement.

         In any such case, either the Representatives or the Company shall have
the right to postpone the applicable Closing Date for a period of not more than
five business days in order that necessary changes and arrangements (including
any necessary amendments or supplements to the Registration Statement or
Prospectus) may be effected by the Representatives and the Company. If the
number of Shares to be purchased on such Closing Date by such defaulting
Underwriter or Underwriters shall exceed 10% of the Shares that all the
Underwriters are obligated to purchase on such Closing Date, and none of the
nondefaulting Underwriters or the Company shall make arrangements pursuant to
this Section within the period stated for the purchase of the Shares that the
defaulting Underwriters agreed to purchase, this Agreement shall terminate with
respect to the Shares to be purchased on such Closing Date without liability on
the part of any nondefaulting Underwriter to the Company and without liability
on the part of the Company, except in both cases as provided in Sections 6(b),
7, 8 and 9. The provisions of this Section shall not in any way affect the
liability of any defaulting Underwriter to the Company or the nondefaulting
Underwriters arising out of such default. A substitute underwriter hereunder
shall become an Underwriter for all purposes of this Agreement.

         11.      Miscellaneous. The respective agreements, representations,
warranties, indemnities and other statements of the Company or its officers and
of the Underwriters set forth in or made pursuant to this Agreement shall remain
in full force and effect, regardless of any investigation made by or on behalf
of any Underwriter or the Company or any of the officers, directors or
controlling persons referred to in Sections 7 and 8 hereof, and shall survive
delivery of and payment for the Shares. The provisions of Sections 6(b), 7, 8
and 9 shall survive the termination or cancellation of this Agreement.

         This Agreement has been and is made for the benefit of the
Underwriters, the Company and their respective successors and assigns and, to
the extent expressed herein, for the benefit of persons controlling any of the
Underwriters, or the Company, and directors and officers of the Company, and
their respective successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. The term "successors and
assigns" shall not include any purchaser of Shares from any Underwriter merely
because of such purchase.

         All notices and communications hereunder shall be in writing and mailed
or delivered, or by telefax or telegraph if subsequently confirmed by letter,
(a) if to the Representatives, to Rodman & Renshaw, Inc., 225 Liberty Street, 2

which shall be an original, with the same effect as if the signatures thereto

                         THE TRANSFER OF THIS WARRANT IS
                         RESTRICTED AS DESCRIBED HEREIN.


                         U.S. MEDICAL INSTRUMENTS, INC.

                    Warrant for the Purchase of Common Shares


No. R-1                                                      [__________] Shares

                  THIS CERTIFIES that, for receipt in hand of [$______] and
other value received, Rodman & Renshaw, Inc. (the "Holder"), is entitled to
subscribe for and purchase from U.S. Medical Instruments, Inc., a California
corporation (the "Company"), upon the terms and conditions set forth herein, at
any time or from time to time after one year after the effective date of the
Registration Statement on Form S-1, and before 5:00 P.M. on five years after the
effective date, New York time (the "Exercise Period"), ___________________
[equal to 10% of the number of shares of Common Stock in the Offering] shares of
the Company's Common Shares, ("Common Stock"), at a price of $_____ per Share
[120% of the Offering price] (the "Exercise Price"). This Warrant is the warrant
or one of the warrants (collectively, including any warrants issued upon the
exercise or transfer of any such warrants, in whole or in part, the "Warrants")
issued pursuant to the Underwriting Agreement, dated __________, 1996, between
Rodman & Renshaw, Inc., as representatives of the several Underwriters named
therein, and the Company. This Warrant may not be sold, transferred, assigned or
hypothecated until [one year after the effective date] except that it may be
transferred, in whole or in part, to (i) one or more officers or partners of
Rodman & Renshaw, Inc. (or the officers or partners of any such partner); (ii)
any other underwriting firm or member of the selling group which participated in
the public offering of Common Stock (the "Offering") which commenced on
[effective date] (or the officers or partners of any such firm); (iii) a
successor to Rodman & Renshaw, Inc., or the officers or partners of such
successor; (iv) a purchaser of substantially all of the assets of Rodman &
Renshaw, Inc.; or (v) by operation of law. The term the "Holder" as used herein
shall include any transferee to whom this Warrant has been transferred in
accordance with the above.

                  The number of shares of Common Stock issuable upon exercise of
the Warrants (the "Warrant Shares") and the Exercise Price may be adjusted from
time to time as hereinafter set forth.

                  1. This Warrant may be exercised during the Exercise Period,
as to the whole or any lesser number of whole Warrant Shares, by the surrender
of this Warrant (with the election in the form attached hereto duly executed) to
the Company at its office at 16825 Via Del Campo Court, San Diego, California
92127, or at such other place as is designated in writing by the Company,
together with a certified or bank cashier's check payable to the order of the
Company in an
<PAGE>   2
amount equal to the Exercise Price multiplied by the number of Warrant Shares
for which this Warrant is being exercised (the "Stock Purchase Price").

                  2. (a) In lieu of the payment of the Stock Purchase Price, the
Holder shall have the right (but not the obligation), to require the Company to
convert this Warrant, in whole or in part, into shares of Common Stock (the
"Conversion Right") as provided for in this Section 2. Upon exercise of the
Conversion Right, the Company shall deliver to the Holder (without payment by
the Holder of any of the Stock Purchase Price) that number of shares of Common
Stock (the "Conversion Shares") equal to the quotient obtained by dividing (x)
the value of this Warrant (or portion thereof as to which the Conversion Right
is being exercised if the Conversion Right is being exercised in part) at the
time the Conversion Right is exercised (determined by subtracting the aggregate
Stock Purchase Price of the shares of Common Stock as to which the Conversion
Right is being exercised in effect immediately prior to the exercise of the
Conversion Right from the aggregate Current Market Price (as defined in Section 
6(c) hereof) of the shares of Common Stock as to which the Conversion Right is
being exercised immediately prior to the exercise of the Conversion Right) by
(y) the Current Market Price of one share of Common Stock immediately prior to
the exercise of the Conversion Right.

                     (b)  The Conversion Rights provided under this Section 2 
may be exercised in whole or in part and at any time and from time to time while
any Warrants remain outstanding. In order to exercise the Conversion Right, the
Holder shall surrender to the Company, at its offices, this Warrant with the
Notice of Conversion in the form attached hereto duly executed. The presentation
and surrender shall be deemed a waiver of the Holder's obligation to pay all or
any portion of the aggregate purchase price payable for the shares of Common
Stock as to which such Conversion Right is being exercised. This Warrant (or so
much thereof as shall have been surrendered for conversion) shall be deemed to
have been converted immediately prior to the close of business on the day of
surrender of such Warrant for conversion in accordance with the foregoing
provisions.

                  3. Upon each exercise of the Holder's rights to purchase
Warrant Shares or Conversion Shares, the Holder shall be deemed to be the holder
of record of the Warrant Shares or Conversion Shares issuable upon such exercise
or conversion, notwithstanding that the transfer books of the Company shall then
be closed or certificates representing such Warrant Shares or Conversion Shares
shall not then have been actually delivered to the Holder. As soon as
practicable after each such exercise or conversion of this Warrant, the Company
shall issue and deliver to the Holder a certificate or certificates for the
Warrant Shares or Conversion Shares issuable upon such exercise or conversion,
registered in the name of the Holder or its designee. If this Warrant should be
exercised or converted in part only, the Company shall, upon surrender of this
Warrant for cancellation, execute and deliver a new Warrant evidencing the right
of the Holder to purchase the balance of the Warrant Shares (or portions
thereof) subject to purchase hereunder.

                  4. Any Warrants issued upon the transfer or exercise or
conversion in part of this Warrant shall be numbered and shall be registered in
a Warrant Register as they are issued. The Company shall be entitled to treat
the registered holder of any Warrant on the Warrant Register as the owner in
fact


                                      - 2 -
<PAGE>   3
thereof for all purposes and shall not be bound to recognize any equitable or
other claim to or interest in such Warrant on the part of any other person, and
shall not be liable for any registration or transfer of Warrants which are
registered or to be registered in the name of a fiduciary or the nominee of a
fiduciary unless made with the actual knowledge that a fiduciary or nominee is
committing a breach of trust in requesting such registration or transfer, or
with the knowledge of such facts that its participation therein amounts to bad
faith. [This Warrant shall be transferable only on the books of the Company upon
delivery thereof duly endorsed by the Holder or by his duly authorized attorney
or representative, or accompanied by proper evidence of succession, assignment,
or authority to transfer.] In all cases of transfer by an attorney, executor,
administrator, guardian, or other legal representative, duly authenticated
evidence of his or its authority shall be produced. Upon any registration of
transfer, the Company shall deliver a new Warrant or Warrants to the person(s)
entitled thereto. This Warrant may be exchanged, at the option of the Holder
thereof, for another Warrant, or other Warrants of different denominations, of
like tenor and representing in the aggregate the right to purchase a like number
of Warrant Shares (or portions thereof), upon surrender to the Company or its
duly authorized agent. Notwithstanding the foregoing, the Company shall have no
obligation to cause Warrants to be transferred on its books to any person if, in
the opinion of counsel to the Company, such transfer does not comply with the
provisions of the Securities Act of 1933, as amended (the "Act"), and the rules
and regulations thereunder.

                  5. The Company shall at all times reserve and keep available
out of its authorized and unissued Common Stock, solely for the purpose of
providing for the exercise of the rights to purchase all Warrant Shares and/or
Conversion Shares granted pursuant to the Warrants, such number of shares of
Common Stock as shall, from time to time, be sufficient therefor. The Company
covenants that all shares of Common Stock issuable upon exercise of this
Warrant, upon receipt by the Company of the full Exercise Price therefor, and
all shares of Common Stock issuable upon conversion of this Warrant, shall be
validly issued, fully paid, and nonassessable, without any personal liability
attaching to the ownership thereof, and will not be issued in violation of any
preemptive rights of stockholders, optionholders, warrantholders and any other
persons and the Holders will receive good title to the securities purchased by
them, respectively, free and clear of all liens, security interests, pledges,
charges, encumbrances, stockholders' agreements and voting trusts which might be
created by acts or omissions to act of the Company.

                  6. (a) In case the Company shall at any time after the date
the Warrants were first issued (i) declare a dividend on the outstanding Common
Stock payable in shares of its capital stock, (ii) subdivide the outstanding
Common Stock, (iii) combine the outstanding Common Stock into a smaller number
of shares, or (iv) issue any shares of its capital stock by reclassification of
the Common Stock (including any such reclassification in connection with a
consolidation or merger in which the Company is the continuing corporation),
then, in each case, the Exercise Price, and the number and kind of securities
issuable upon exercise or conversion of this Warrant, in effect at the time of
the record date for such dividend or of the effective date of such subdivision,
combination, or reclassification, shall be proportionately adjusted so that the
Holder after such time shall be entitled to receive the aggregate number and
kind of shares which, if such Warrant had been exercised or converted


                                      - 3 -
<PAGE>   4
immediately prior to such time, he would have owned upon such exercise or
conversion and been entitled to receive by virtue of such dividend, subdivision,
combination, or reclassification. Such adjustment shall be made successively
whenever any event listed above shall occur.

                  (b) In case the Company shall distribute to all holders of
Common Stock (including any such distribution made to the stockholders of the
Company in connection with a consolidation or merger in which the Company is the
continuing corporation) evidences of its indebtedness, cash (other than any cash
dividend which, together with any cash dividends paid within the 12 months prior
to the record date for such distribution, does not (on a per share basis) exceed
5% of the Current Market Price per share of Common Stock at the record date for
such distribution) or assets (other than distributions and dividends payable in
shares of Common Stock), or rights, options, or warrants to subscribe for or
purchase Common Stock, or securities convertible into or exchangeable for shares
of Common Stock, then, in each case, the Exercise Price shall be adjusted by
multiplying the Exercise Price in effect immediately prior to the record date
for the determination of stockholders entitled to receive such distribution by a
fraction, the numerator of which shall be the Current Market Price per share of
Common Stock on such record date, less the fair market value (as determined in
good faith by the board of directors of the Company, whose determination shall
be conclusive absent manifest error) of the portion of the evidences of
indebtedness or assets so to be distributed, or of such rights, options, or
warrants or convertible or exchangeable securities, or the amount of such cash,
applicable to one share, and the denominator of which shall be such Current
Market Price per share of Common Stock. Such adjustment shall be made whenever
any such distribution is made, and shall become effective on the record date for
the determination of stockholders entitled to receive such distribution.

                  (c) For the purpose of any computation under this Section 6,
the Current Market Price per share of Common Stock on any date shall be deemed
to be the average of the daily closing prices for the 30 consecutive trading
days immediately preceding the date in question. The closing price for each day
shall be the last reported sales price regular way or, in case no such reported
sale takes place on such day, the closing bid price regular way, in either case
on the principal national securities exchange (including, for purposes hereof,
the NASDAQ National Market System) on which the Common Stock is listed or
admitted to trading or, if the Common Stock is not listed or admitted to trading
on any national securities exchange, the highest reported bid price for the
Common Stock as furnished by the National Association of Securities Dealers,
Inc. through NASDAQ or a similar organization if NASDAQ is no longer reporting
such information. If on any such date the Common Stock is not listed or admitted
to trading on any national securities exchange and is not quoted by NASDAQ or
any similar organization, the fair value of a share of Common Stock on such
date, as determined in good faith by the board of directors of the Company,
whose determination shall be conclusive absent manifest error, shall be used.

                  (d) No adjustment in the Exercise Price shall be required if
such adjustment is less than $.05; provided, however, that any adjustments which
by reason of this Section 6 are not required to be made shall be carried forward
and taken into account in any subsequent adjustment. All calculations under


                                      - 4 -
<PAGE>   5
this Section 6 shall be made to the nearest cent or to the nearest 
one-thousandth of a share, as the case may be.

                  (e) In any case in which this Section 6 shall require that an
adjustment in the Exercise Price be made effective as of a record date for a
specified event, the Company may elect to defer, until the occurrence of such
event, issuing to the Holder, if the Holder exercised or converted this Warrant
after such record date, the shares of Common Stock, if any, issuable upon such
exercise or conversion over and above the shares of Common Stock, if any,
issuable upon such exercise or conversion on the basis of the Exercise Price in
effect prior to such adjustment; provided, however, that the Company shall
deliver to the Holder a due bill or other appropriate instrument evidencing the
Holder's right to receive such additional shares upon the occurrence of the
event requiring such adjustment.

                  (f) Upon each adjustment of the Exercise Price as a result of
the calculations made in Section 6(b) hereof, this Warrant shall thereafter
evidence the right to purchase, at the adjusted Exercise Price, that number of
shares (calculated to the nearest thousandth) obtained by dividing (i) the
product obtained by multiplying the number of shares purchasable upon exercise
of this Warrant prior to adjustment of the number of shares by the Exercise
Price in effect prior to adjustment of the Exercise Price, by (ii) the Exercise
Price in effect after such adjustment of the Exercise Price.

                  (g) Whenever there shall be an adjustment as provided in this
Section 6, the Company shall promptly cause written notice thereof to be sent by
registered mail, postage prepaid, to the Holder, at its address as it shall
appear in the Warrant Register, which notice shall be accompanied by an
officer's certificate setting forth the number of Warrant Shares purchasable
upon the exercise of this Warrant and the Exercise Price after such adjustment
and setting forth a brief statement of the facts requiring such adjustment and
the computation thereof, which officer's certificate shall be conclusive
evidence of the correctness of any such adjustment absent manifest error.

                  (h) The Company shall not be required to issue fractions of
shares of Common Stock or other capital stock of the Company upon the exercise
or conversion of this Warrant. If any fraction of a share would be issuable on
the exercise or conversion of this Warrant (or specified portions thereof), the
Company shall purchase such fraction for an amount in cash equal to the same
fraction of the Current Market Price of such share of Common Stock on the date
of exercise or conversion of this Warrant.

                  7. (a) In case of any consolidation with or merger of the
Company with or into another corporation (other than a merger or consolidation
in which the Company is the surviving or continuing corporation), or in case of
any sale, lease, or conveyance to another corporation of the property and assets
of any nature of the Company as an entirety or substantially as an entirety,
such successor, leasing, or purchasing corporation, as the case may be, shall
(i) execute with the Holder an agreement providing that the Holder shall have
the right thereafter to receive upon exercise or conversion of this Warrant
solely the kind and amount of shares of stock and other securities, property,
cash, or any combination thereof receivable upon such consolidation, merger,
sale, lease, or conveyance by a holder of the number of shares of Common Stock
for which this Warrant might have been exercised or converted immediately prior
to such


                                      - 5 -
<PAGE>   6
consolidation, merger, sale, lease, or conveyance, and (ii) make effective
provision in its certificate of incorporation or otherwise, if necessary, to
effect such agreement. Such agreement shall provide for adjustments which shall
be as nearly equivalent as practicable to the adjustments in Section 6.

                  (b) In case of any reclassification or change of the shares of
Common Stock issuable upon exercise or conversion of this Warrant (other than a
change in par value or from no par value to a specified par value, or as a
result of a subdivision or combination, but including any change in the shares
into two or more classes or series of shares), or in case of any consolidation
or merger of another corporation into the Company in which the Company is the
continuing corporation and in which there is a reclassification or change
(including a change to the right to receive cash or other property) of the
shares of Common Stock (other than a change in par value, or from no par value
to a specified par value, or as a result of a subdivision or combination, but
including any change in the shares into two or more classes or series of
shares), the Holder shall have the right thereafter to receive upon exercise or
conversion of this Warrant solely the kind and amount of shares of stock and
other securities, property, cash, or any combination thereof receivable upon
such reclassification, change, consolidation, or merger by a holder of the
number of shares of Common Stock for which this Warrant might have been
exercised or converted immediately prior to such reclassification, change,
consolidation, or merger. Thereafter, appropriate provision shall be made for
adjustments which shall be as nearly equivalent as practicable to the
adjustments in Section 6.

                  (c) The above provisions of this Section 7 shall similarly
apply to successive reclassifications and changes of shares of Common Stock and
to successive consolidations, mergers, sales, leases, or conveyances.

                  8.  In case at any time the Company shall propose

                        (a)   to pay any dividend or make any distribution on
         shares of Common Stock in shares of Common Stock or make any other
         distribution (other than regularly scheduled cash dividends which are
         not in a greater amount per share than the most recent such cash
         dividend) to all holders of Common Stock; or

                        (b)   to issue any rights, warrants, or other
         securities to all holders of Common Stock entitling them to purchase
         any additional shares of Common Stock or any other rights, warrants, or
         other securities; or

                        (c)   to effect any reclassification or change of
         outstanding shares of Common Stock, or any consolidation, merger, sale,
         lease, or conveyance of property, described in Section 7; or

                        (d)   to effect any liquidation, dissolution, or 
         winding-up of the Company; or

                        (e)   to take any other action which would cause an
         adjustment to the Exercise Price;


                                      - 6 -
<PAGE>   7
then, and in any one or more of such cases, the Company shall give written
notice thereof, by registered mail, postage prepaid, to the Holder at the
Holder's address as it shall appear in the Warrant Register, mailed at least 15
days prior to (i) the date as of which the holders of record of shares of Common
Stock to be entitled to receive any such dividend, distribution, rights,
warrants, or other securities are to be determined, (ii) the date on which any
such reclassification, change of outstanding shares of Common Stock,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up is expected to become effective, and the date as of
which it is expected that holders of record of shares of Common Stock shall be
entitled to exchange their shares for securities or other property, if any,
deliverable upon such reclassification, change of outstanding shares,
consolidation, merger, sale, lease, conveyance of property, liquidation,
dissolution, or winding-up, or (iii) the date of such action which would require
an adjustment to the Exercise Price.

                  9. The issuance of any shares or other securities upon the
exercise or conversion of this Warrant, and the delivery of certificates or
other instruments representing such shares or other securities, shall be made
without charge to the Holder for any tax or other charge in respect of such
issuance. The Company shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issue and delivery of any
certificate in a name other than that of the Holder and the Company shall not be
required to issue or deliver any such certificate unless and until the person or
persons requesting the issue thereof shall have paid to the Company the amount
of such tax or shall have established to the satisfaction of the Company that
such tax has been paid.

                  10. (a) Subject to the conditions set forth below, the Company
agrees to indemnify and hold harmless each Eligible Holder, its officers,
directors, partners, employees, agents, and counsel, and each person, if any,
who controls any such person within the meaning of Section 15 of the Act or
Section 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), from and against any and all loss, liability, charge, claim, damage, and
expense whatsoever (which shall include, for all purposes of this Section 10,
but not be limited to, reasonable attorneys' fees and any and all reasonable
expense whatsoever incurred in investigating, preparing, or defending against
any litigation, commenced or threatened, or any claim whatsoever, and any and
all amounts paid in settlement of any claim or litigation), as and when
incurred, arising out of, based upon, or in connection with (i) any untrue
statement or alleged untrue statement of a material fact contained (A) in any
registration statement, preliminary prospectus, or final prospectus (as from
time to time amended and supplemented), or any amendment or supplement thereto,
relating to the sale of any of the Underwriters' Securities, or (B) in any
application or other document or communication (in this Section 10 collectively
called an "application") executed by or on behalf of the Company or based upon
written information furnished by or on behalf of the Company filed in any
jurisdiction in order to register or qualify any of the Underwriters' Securities
under the securities or blue sky laws thereof or filed with the Commission or
any securities exchange; or any omission or alleged omission to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading, unless such statement or omission was made in reliance upon and
in conformity with written information furnished to the Company with respect to


                                      - 7 -
<PAGE>   8
such Eligible Holder by or on behalf of such person expressly for inclusion in
any registration statement, preliminary prospectus, or final prospectus, or any
amendment or supplement thereto, or in any application, as the case may be, or
(ii) any breach of any representation, warranty, covenant, or agreement of the
Company contained in this Warrant. The foregoing agreement to indemnify shall be
in addition to any liability the Company may otherwise have, including
liabilities arising under this Warrant.

                  If any action is brought against any Eligible Holder or any of
its officers, directors, partners, employees, agents, or counsel, or any
controlling persons of such person (an "indemnified party") in respect of which
indemnity may be sought against the Company pursuant to the foregoing paragraph,
such indemnified party or parties shall promptly notify the Company in writing
of the institution of such action (but the failure so to notify shall not
relieve the Company from any liability pursuant to this Section 10(a)) and the
Company shall promptly assume the defense of such action, including the
employment of counsel (reasonably satisfactory to such indemnified party or
parties) and payment of expenses. Such indemnified party or parties shall have
the right to employ its or their own counsel in any such case, but the fees and
expenses of such counsel shall be at the expense of such indemnified party or
parties unless the employment of such counsel shall have been authorized in
writing by the Company in connection with the defense of such action or the
Company shall not have promptly employed counsel reasonably satisfactory to such
indemnified party or parties to have charge of the defense of such action or
such indemnified party or parties shall have reasonably concluded that there may
be one or more legal defenses available to it or them or to other indemnified
parties which are different from or additional to those available to the
Company, in any of which events such fees and expenses shall be borne by the
Company and the Company shall not have the right to direct the defense of such
action on behalf of the indemnified party or parties. Anything in this Section 
10 to the contrary notwithstanding, the Company shall not be liable for any
settlement of any such claim or action effected without its written consent,
which shall not be unreasonably withheld. The Company shall not, without the
prior written consent of each indemnified party that is not released as
described in this sentence, settle or compromise any action, or permit a default
or consent to the entry of judgment in or otherwise seek to terminate any
pending or threatened action, in respect of which indemnity may be sought
hereunder (whether or not any indemnified party is a party thereto), unless such
settlement, compromise, consent, or termination includes an unconditional
release of each indemnified party from all liability in respect of such action.

                  (b) The Holder agrees to indemnify and hold harmless the
Company, each director of the Company, each officer of the Company who shall
have signed any registration statement covering Underwriters' Securities held by
the Holder, each other person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, and its
or their respective counsel, to the same extent as the foregoing indemnity from
the Company to the Holder in Section 10(a), but only with respect to statements
or omissions, if any, made in any registration statement, preliminary
prospectus, or final prospectus (as from time to time amended and supplemented),
or any amendment or supplement thereto, or in any application, in reliance upon
and in conformity with written information furnished to the Company with respect
to the Holder by or on behalf of the Holder expressly for inclusion in any such


                                      - 8 -
<PAGE>   9
registration statement, preliminary prospectus, or final prospectus, or any
amendment or supplement thereto, or in any application, as the case may be. If
any action shall be brought against the Company or any other person so
indemnified based on any such registration statement, preliminary prospectus, or
final prospectus, or any amendment or supplement thereto, or in any application,
and in respect of which indemnity may be sought against the Holder pursuant to
this Section 10(b), the Holder shall have the rights and duties given to the
Company, and the Company and each other person so indemnified shall have the
rights and duties given to the indemnified parties, by the provisions of 
Section 10(a).

                  (c) To provide for just and equitable contribution, if (i) an
indemnified party makes a claim for indemnification pursuant to Section 10(a) or
11(b) (subject to the limitations thereof) but it is found in a final judicial
determination, not subject to further appeal, that such indemnification may not
be enforced in such case, even though this Agreement expressly provides for
indemnification in such case, or (ii) any indemnified or indemnifying party
seeks contribution under the Act, the Exchange Act or otherwise, then the
Company (including for this purpose any contribution made by or on behalf of any
director of the Company, any officer of the Company who signed any such
registration statement, any controlling person of the Company, and its or their
respective counsel), as one entity, and the Eligible Holders of the
Underwriters' Securities included in such registration in the aggregate
(including for this purpose any contribution by or on behalf of an indemnified
party), as a second entity, shall contribute to the losses, liabilities, claims,
damages, and expenses whatsoever to which any of them may be subject, on the
basis of relevant equitable considerations such as the relative fault of the
Company and such Eligible Holders in connection with the facts which resulted in
such losses, liabilities, claims, damages, and expenses. The relative fault, in
the case of an untrue statement, alleged untrue statement, omission, or alleged
omission, shall be determined by, among other things, whether such statement,
alleged statement, omission, or alleged omission relates to information supplied
by the Company or by such Eligible Holders, and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement, alleged statement, omission, or alleged omission. The Company and the
Holder agree that it would be unjust and inequitable if the respective
obligations of the Company and the Eligible Holders for contribution were
determined by pro rata or per capita allocation of the aggregate losses,
liabilities, claims, damages, and expenses (even if the Holder and the other
indemnified parties were treated as one entity for such purpose) or by any other
method of allocation that does not reflect the equitable considerations referred
to in this Section 10(c). In no case shall any Eligible Holder be responsible
for a portion of the contribution obligation imposed on all Eligible Holders in
excess of its pro rata share based on the number of shares of Common Stock owned
(or which would be owned upon exercise of all Underwriters' Securities) by it
and included in such registration as compared to the number of shares of Common
Stock owned (or which would be owned upon exercise of all Underwriters'
Securities) by all Eligible Holders and included in such registration. No person
guilty of a fraudulent misrepresentation (within the meaning of Section 10(f) of
the Act) shall be entitled to contribution from any person who is not guilty of
such fraudulent misrepresentation. For purposes of this Section 10(c), each
person, if any, who controls any Eligible Holder within the meaning of Section 
15 of the Act or Section 20(a) of

             
                                      - 9 -
<PAGE>   10
the Exchange Act and each officer, director, partner, employee, agent, and
counsel of each such Eligible Holder or control person shall have the same
rights to contribution as such Eligible Holder or control person and each
person, if any, who controls the Company within the meaning of Section 15 of the
Act or Section 20(a) of the Exchange Act, each officer of the Company who shall
have signed any such registration statement, each director of the Company, and
its or their respective counsel shall have the same rights to contribution as
the Company, subject in each case to the provisions of this Section 10(c).
Anything in this Section 10(c) to the contrary notwithstanding, no party shall
be liable for contribution with respect to the settlement of any claim or action
effected without its written consent. This Section 10(c) is intended to
supersede any right to contribution under the Act, the Exchange Act or
otherwise.

                  13. Upon receipt of evidence satisfactory to the Company of
the loss, theft, destruction, or mutilation of any Warrant (and upon surrender
of any Warrant if mutilated), and upon reimbursement of the Company's reasonable
incidental expenses, the Company shall execute and deliver to the Holder thereof
a new Warrant of like date, tenor, and denomination.

                  14. The Holder of any Warrant shall not have, solely on
account of such status, any rights of a stockholder of the Company, either at
law or in equity, or to any notice of meetings of stockholders or of any other
proceedings of the Company, except as provided in this Warrant.

                  15. This Warrant shall be construed in accordance with the
laws of the State of New York applicable to contracts made and performed within
such State, without regard to principles of conflicts of law.

                              AMENDED AND RESTATED

                            ARTICLES OF INCORPORATION
                        OF U.S. MEDICAL INSTRUMENTS, INC.

         The undersigned, Matthew S. Mazur and Carl R. Brown, hereby certify
that:

         ONE: They are the duly elected and acting Chairman and Chief Executive
Officer and Secretary, respectively, of this Corporation.

         TWO: The Articles of Incorporation of this Corporation shall be amended
and restated to read in full as follows:

                                    ARTICLE I

         The name of this Corporation is U. S. Medical Instruments, Inc.

                                   ARTICLE II

         The purpose of this Corporation is to engage in any lawful act or
activity for which a Corporation may be organized under the General Corporation
Law of California other than the banking business, the trust company business or
the practice of a profession permitted to be incorporated by the California
Corporations Code.

                                   ARTICLE III

         (A) Classes of Stock. This Corporation is authorized to issue two
classes of stock to be designated, respectively, "Common Stock" and "Preferred
Stock." The total number of shares which the Corporation is authorized to issue
is Forty Million (40,000,000) shares. Twenty-eight Million (28,000,000) shares
shall be Common Stock and Twelve Million (12,000,000) shares shall be Preferred
Stock.

         (B) Rights, Preferences, Privileges and Restrictions of Preferred
Stock. The Preferred Stock authorized by these Restated Articles of
Incorporation may be issued from time to time in series. The rights, preferences
privileges and restrictions granted to and imposed on the Series A Preferred
Stock, which series shall consist of 1,332,000 shares, the Series B Preferred
Stock, which series shall consist of 937,150 shares, the Series C Preferred
Stock, which series shall consist of 222,020 shares, the Series D Preferred
Stock, which series shall consist of 1,780,000 shares, the Series E Preferred
Stock, which series shall consist of 2,500,000 shares and the Series F Preferred
Stock, which Series shall consist of 3,000,000 shares are as set forth below in
this Article III(B).

Except as to the Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock and except as otherwise provided in these Restated Articles of
Incorporation, the Board of Directors is hereby authorized to fix or alter the
rights, preferences, privileges and restrictions granted to or imposed upon any
wholly unissued additional series of Preferred Stock, and the number of shares
constituting any such series and the designation thereof, or any of them. The
Board of Directors, except as otherwise provided 


Articles of Incorporation                                             Page 1
<PAGE>   2
in these Articles of Incorporation, is also authorized to decrease the number of
shares of any series, subsequent to the issuance of shares in that series, but
not below the number of shares of such series then outstanding. In case the
number of shares of any series shall be so decreased, the shares constituting
such decrease shall resume the status which they had prior to the adoption of
the resolution originally fixing the number of shares of such series.

         1. Dividend Provisions. The holders of shares of Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock shall be entitled to
receive dividends, out of any assets legally available therefor, prior and in
preference to any declaration or payment of any dividend (payable other than in
Common Stock or other securities and rights convertible into or entitling the
holder thereof to receive, directly or indirectly, additional shares of Common
Stock of this Corporation) on the Common Stock of this Corporation, at the rate
of $0.002, $0.21, $0.28, $0.56, $0.75 and $1.00 respectively, per share per
annum or, if greater (as determined on an as-converted basis for the Series A,
Series B, Series C, Series D, Series E and Series F Preferred Stock), an amount
equal to that paid on any other outstanding shares of this Corporation whenever
funds are legally available therefor, payable annually when, as and if declared
by the Board of Directors. No dividend shall be declared and or paid with
respect to any series of Preferred Stock unless a dividend is declared and or
paid with respect to each series of outstanding Preferred Stock at a rate that
is no less favorable to the Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock than $0.002, $0.21, $0.28, $0.56, $0.75 and $1.00 for
each share of Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock, respectively. Such dividends shall not be cumulative.

         2. Liquidation Preference.

                  (a) In the event of any liquidation, dissolution or winding up
of this Corporation, either voluntary or involuntary, the holders of Series A,
Series B, Series C, Series D, Series E and Series F Preferred Stock shall be
entitled to receive, prior and in preference to any distribution of any of the
assets of this Corporation to the holders of Common Stock by reason of their
ownership thereof, an amount per share equal to $0.02 for each share of Series A
Preferred Stock (the "Original Series A Issue Price"), $2.10 per share of Series
B Preferred Stock (the "Original Series B Issue Price"), $2.80 per share of
Series C Preferred Stock (the "Original Series C Issue Price"), $5.60 per share
of Series D Preferred Stock (the "Original Series D Issue Price"), $7.50 per
share of Series E Preferred Stock (the "Original Series E Issue Price") and
$10.00 per share of Series F Preferred Stock (the "Original Series F Issue
Price") plus, in each case, an amount equal to all declared but unpaid dividends
thereon. If, upon the occurrence of such an event, the assets and property thus
distributed among the holders of the Series A, Series B, Series C and Series D,
Series E and Series F Preferred Stock shall be insufficient to permit the
payment to such holders of the full preferential amount, then the assets and
property of the Corporation legally available for distribution shall be
distributed pro rata among the holders of the Series A, Series B, Series C,
Series D, Series E and Series F Preferred Stock in proportion to the aggregate
preferential amounts owed such holders of the outstanding Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock upon a liquidation,
dissolution or winding up of the Corporation.

                  (b) After the distributions described in subsection (a) above
have been paid, the remaining assets of the Corporation available for
distribution to shareholders shall be distributed


Articles of Incorporation                                             Page 2
<PAGE>   3
among the holders of Common Stock pro rata, based on the number of shares of
Common Stock held by each.

                  (c) A merger of this Corporation with or into any other
corporation or corporations, or a sale, conveyance or disposition of all or
substantially all of the assets of this Corporation or the effectuation by the
Corporation of a transaction or series of related transactions in which more
than 50% of the voting power of the Corporation is disposed of, shall not be
deemed to be a liquidation, dissolution or winding up within the meaning of this
Section 2, but shall instead be treated pursuant to Section 5 hereof.

         3. Redemption.

                  (a) On or at any time after April 30, 1996 this Corporation
may, at any time it may lawfully do so, at the option of the Board of Directors,
redeem in whole or in part the Series A, Series B, Series C, Series D, Series E
and Series F Preferred Stock by paying in cash therefor a sum per share equal to
the Original Series A Issue Price, the Original Series B Issue Price, the
Original Series C Issue Price, the Original Series D Issue Price, the Original
Series E Issue Price or the Original Series F Issue Price, as the case may be,
plus any declared but unpaid dividends on such shares to the Redemption Date
(such total amount is hereinafter referred to as the "Redemption Price").

                  (b)      (i) In the event of any redemption of only a part of
the then outstanding Series A, Series B, Series C, Series D, Series E or Series
F Preferred Stock, this Corporation shall redeem the same proportion of each
outstanding series of Preferred Stock and, as to each such series, shall effect
such redemption pro rata according to the number of shares held by each holder
thereof. No redemption of any series of Preferred Stock shall occur, unless
there is a pro rata redemption of all series of Preferred Stock in accordance
with the foregoing. In the event of any redemption of all or part of the then
outstanding Series A, Series B, Series C, Series D, Series E or Series F
Preferred Stock, any holder thereof may avoid all or part of such redemption by
converting into Common Stock, pursuant to Section 4 below, up to that number of
shares of such holder's Preferred stock scheduled to be redeemed in such
redemption. Such holder may condition such conversion on deposit by the
Corporation of the Redemption Price for the shares to be redeemed pursuant to
subsection 3 (b)(iv) below.

                           (ii) At least 30 but no more than 60 days prior to
the date fixed for any redemption of Series A, Series B, Series C, Series D,
Series E and Series F Preferred Stock (the "Redemption Date"), written notice
shall be mailed, first class postage prepaid, to each holder of record (at the
close of business on the business day next preceding the day on which notice is
given) of the Series A, Series B, Series C, Series D and Series E Preferred
Stock to be redeemed, at the address last shown on the records of this
Corporation for such holder or given by the holder to this Corporation for the
purpose of notice, notifying such holder of the redemption to be effected,
specifying the number of shares to be redeemed from such holder, the Redemption
Date, the Redemption Price, the place at which payment may be obtained and the
date on which such holder's Conversion Rights (as hereinafter defined) as to
such shares terminate and calling upon such holder to surrender to this
Corporation, in the manner and at the place designated, his certificate or
certificates representing the shares to be redeemed (the "Redemption Notice").
Except as provided in subsection 3(b)(iii), on or after the Redemption Date,
each holder of Series A, Series B, Series C, Series D, Series E or Series F
Preferred Stock to be redeemed 


Articles of Incorporation                                             Page 3
<PAGE>   4
shall surrender to this Corporation the certificate or certificates representing
such shares, in the manner and at the place designated in the Redemption Notice,
and thereupon the Redemption Price of such shares shall be payable to the order
of the person whose name appears on such certificate or certificates as the
owner thereof and each surrendered certificate shall be canceled. In the event
less than all the shares represented by any such certificate are redeemed, a new
certificate shall be issued representing the unredeemed shares.

                           (iii) From and after the Redemption Date, unless
there shall have been a default in payment of the Redemption Price, all
dividends on the Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock designated for redemption in the Redemption Notice shall cease
to accrue, all rights of the holders of such shares as holders of Series A,
Series B, Series C, Series D, Series E and Series F Preferred Stock (except the
right to receive the Redemption Price without interest upon surrender of their
certificate or certificates) shall cease with respect to such shares, and such
shares shall not thereafter be transferred on the books of this Corporation or
be deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock on any Redemption Date
are insufficient to redeem the total number of shares of Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock to be redeemed on such
date, those funds which are legally available will be used to redeem the maximum
possible number of such shares in accordance with the provisions of paragraph
3(b)(i) hereof The shares of Series A, Series B, Series C, Series D, Series E
and Series F Preferred Stock not redeemed shall remain outstanding and entitled
to all the rights and preferences provided herein. At any time thereafter when
additional funds of the Company are legally available for the redemption of
shares of Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock, such funds will immediately be used to redeem the balance of
the shares which the Company has become obligated to redeem on any Redemption
Date but which it has not redeemed.

                           (iv) Three days prior to the Redemption Date: this
Corporation shall deposit the Redemption Price of all outstanding shares of
Series A, Series B, Series C, Series D, Series E and Series F Preferred Stock
designated for redemption in the Redemption Notice, and not yet redeemed or
converted, with a bank or trust company having aggregate capital and surplus in
excess of $50,000,000 as a trust fund for the benefit of the respective holders
of the shares designated for redemption and not yet redeemed. Simultaneously,
this Corporation shall deposit irrevocable instruction and authority to such
bank or trust company to publish the notice of redemption thereof (or to
complete such publication if theretofore commenced) and to pay, on and after the
date fixed for redemption or prior thereto, the Redemption Price of the Series
A, Series B, Series C, Series D, Series E and Series F Preferred Stock to the
holders thereof upon surrender of their certificates. Any monies deposited by
this Corporation pursuant to this subsection 3(b)(iv) for the redemption of
shares which are thereafter converted into shares of Common Stock pursuant to
Section 4 hereof no later than the close of business on the Redemption Date
shall be returned to this Corporation forthwith upon such conversion. The
balance of any monies deposited by this Corporation pursuant to this subsection
3 (b)(iv) remaining unclaimed at the expiration of two years following the
Redemption Date shall thereafter be returned to this Corporation, provided that
the shareholder to, which such money would be payable hereunder shall be
entitled, upon proof of its ownership of the Series A, Series B, Series C,
Series D, Series E and Series F Preferred Stock and payment of any bond
requested by the Company, to receive such monies but without interest from the
Redemption Date.

         4. Conversion. The holders of the Series A, Series B, Series C, Series
D, Series E and Series F Preferred Stock shall have conversion rights as follows
(the "Conversion Rights"):


Articles of Incorporation                                             Page 5
<PAGE>   6
                  (a) Right to Convert.

                           (i) Subject to subsection (c), each share of Series
A, Series B, Series C, Series D, Series E and Series F Preferred Stock shall be
convertible, at the option of the holder thereof at any time after the date of
issuance of such share and prior to the close of business on any Redemption Date
as may have been fixed in any Redemption Notice with respect to such share, at
the office of this Corporation or any transfer agent for the Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock, into such number of
fully paid and nonassessable shares of Common Stock as is determined by dividing
$0.02 for each share of Series A Preferred Stock, $2.10 for each share of Series
B Preferred Stock, $2.80 for each share of Series C Preferred Stock, $5.60 for
each share of Series D Preferred Stock, $7.50 for each share of Series E
Preferred Stock and $10.00 for each share of Series F Preferred Stock by the
Conversion Price at the time in effect for such share. The initial Conversion
Prices for shares of Preferred Stock shall be $0.02, $2.10, $2.80, $5.60, $7.50
and $10.00 per share for the Series A, Series B, Series C, Series D, Series E
and Series F Preferred Stock, respectively, provided, however, that such
Conversion Prices shall be subject to adjustment as set forth in subsection
4(c).

                           (ii) In the event of a call for redemption of any
shares of Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock pursuant to Section 3 hereof, the Conversion Rights shall
terminate as to the shares designated for redemption at the close of business on
the Redemption Date, unless default is made in payment of the Redemption Price.

                           (iii) Each share of Series A, Series B, Series C,
Series D, Series E and Series F Preferred Stock shall automatically be converted
into shares of Common Stock at the Conversion Price at the time in effect for
such Series A, Series B, Series C, Series D, Series E or Series F Preferred
Stock immediately upon the consummation of the Corporation's sale of its Common
Stock in a bona fide, firm commitment underwriting pursuant to a registration
statement under the Securities Act of 1933, as amended, which results in
aggregate gross cash proceeds to this Corporation in excess of $3,000,000.

                  (b) Mechanics of Conversion. Before any holder of Series A,
Series B, Series C, Series D, Series E or Series F Preferred Stock shall be
entitled to convert the same into shares of Common Stock, he shall surrender the
certificate or certificates therefor, duly endorsed, at the office of this
Corporation or of any transfer agent for the Series A, Series B, Series C,
Series D, Series E or Series F Preferred Stock, and shall give written notice by
mail, postage prepaid, to this Corporation at its principal corporate office, of
the election to convert the same and shall state therein the name or names in
which the certificate or certificates for shares of Common Stock are to be
issued. This Corporation shall, as soon as practicable thereafter, issue and
deliver at such office such holder of Series A, Series B, Series C, Series D,
Series E or Series F Preferred Stock, or to the nominee or nominees of such
holder, a certificate or certificates for the number of shares of Common Stock
to which such holder shall be entitled as aforesaid. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Series A, Series B, Series C, Series D,
Series E or Series F Preferred Stock to be converted, and the person or persons
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such shares
of Common Stock as of such date. If the conversion is in connection with an
underwritten offer of securities registered pursuant to the Securities Act of
1933, the conversion will be 


Articles of Incorporation                                             Page 6
<PAGE>   7
conditioned upon the closing with the underwriter of the sale of securities
pursuant to such offering, unless otherwise designated in writing by the holders
of such Series A, Series B, Series C, Series D, Series E or Series F Preferred
Stock, in which event the person(s) entitled to receive the Common Stock
issuable upon such conversion of the Series A, Series B, Series C, Series D,
Series E or Series F Preferred Stock shall not be deemed to have converted such
Series A, Series B, Series C, Series D, Series E or Series F Preferred Stock
until immediately prior to the closing of such sale of securities.

                  (c) Conversion Price Adjustments of Preferred Stock. The
Conversion Price of each series of Preferred Stock shall be subject to
adjustment from time to time as follows:

                           (i) In the event the Corporation should at any time
or from time to time after the date of first issuance of shares of a particular
series of Preferred Stock (the "Purchase Date" for such series of Preferred
Stock) fix a record date for the effectuation of a split or subdivision of the
outstanding shares of Common Stock or the determination of holders of Common
Stock entitled to receive a dividend or other distribution payable in additional
shares of Common Stock or other securities or rights convertible into, or
entitling the holder thereof to receive directly or indirectly, additional
shares of Common Stock (hereinafter referred to as "Common Stock Equivalents")
without payment of any consideration by such holder for the additional shares of
common Stock or the Common Stock Equivalents (including the additional shares of
Common Stock issuable upon conversion or exercise thereof), then, as of such
record date (or the date of such dividend distribution, split or subdivision if
no record date is fixed), the Conversion Prices of the Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock shall be appropriately
decreased so that the number of shares of Common Stock issuable on conversion of
each share of such series shall be increased in proportion to such increase in
outstanding shares.

                           (ii) If the number of shares of Common Stock
outstanding at any time after the Purchase Date is decreased by a combination of
the outstanding shares of Common Stock, then, following the record date of such
combination, the Conversion Prices for the Series A, Series B, Series C, Series
D, Series E and Series F Preferred Stock shall be appropriately increased so
that the number of shares of Common Stock issuable on conversion of each share
of such series shall be decreased in proportion to such decrease in outstanding
shares.

                  (d) Other Distributions. In the event this Corporation shall
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by this Corporation or other persons, assets (excluding cash
dividends) or options or rights not referred to in subsection 4(c)(i), then, in
each such case for the purpose of this subsection 4(d), the holders of the
Series A, Series B, Series C, Series D, Series E and Series F Preferred Stock
shall be entitled to a proportionate share of any such distribution as though
they were the holders of the number of shares of Common Stock of the Corporation
into which their shares of Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

                  (e) Recapitalizations. If at any time or from time to time
there shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4 or Section 5) provision shall be made so that the holders of the
Series A, Series B, Series C, Series D, Series E and Series F Preferred Stock
shall


Articles of Incorporation                                             Page 7
<PAGE>   8
thereafter be entitled to receive upon conversion of the Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock the number of shares
of stock or other securities or property of the Company or otherwise, to which a
holder of Common Stock deliverable upon conversion would have been entitled on
such recapitalization. In any such case, appropriate adjustment shall be made in
the application of the provisions of this Section 4 with respect to the rights
of the holders of the Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock after the recapitalization to the end that the
provisions of this Section 4 (including adjustment of the Conversion Prices then
in effect and the number of shares purchasable upon conversion of the Series A,
Series B, Series C, Series D, Series E and Series F Preferred Stock) shall be
applicable after that event as nearly equivalent as may be practicable.

                  (f) No Impairment. This Corporation will not, by amendment of
its Articles of Incorporation or through any reorganization, recapitalization,
transfer of assets consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by this
Corporation, but will at all times in good faith assist in the carrying out of
all the provisions of this Section 4 and in the taking of all such action as may
be necessary or appropriate in order to protect the Conversion Rights of the
holders of the Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock against impairment.

                  (g) No Fractional Shares and Certificate as to Adjustments.

                           (i) No fractional shares shall be issued upon
conversion of the Series A, Series B, Series C, Series D, Series E or Series F
Preferred Stock, and the number of shares of Common Stock to be issued shall be
rounded to the nearest whole share. Whether or not fractional shares are
issuable upon such conversion shall be determined on the basis of the total
number of shares of Series A, Series B, Series C, Series D, Series E or Series F
Preferred Stock the holder is at the time converting into Common Stock and the
number of shares of Common Stock issuable upon such aggregate conversion.

                           (ii) Upon the occurrence of each adjustment or
readjustment of any Conversion Price of Series A, Series B, Series C, Series D,
Series E or Series F Preferred Stock pursuant to this Section 4, this
Corporation, at its expense, shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A, Series B, Series C, Series D, Series E or Series F Preferred
Stock a certificate setting forth such adjustment or readjustment and showing in
detail the facts upon which such adjustment or readjustment is based. This
Corporation shall, upon the written request at any time of any holder of Series
A, Series B, Series C, Series D, Series E or Series F Preferred Stock, furnish
or cause to be furnished to such holder a like certificate setting forth (A)
such adjustment and readjustment, (B) the Conversion Prices at the time in
effect, and (C) the number of shares of Common Stock and the amount, if any, of
other property which at the time would be received upon the conversion of a
share of Series A, Series B, Series C, Series D, Series E or Series F Preferred
Stock.

                  (h) Notices of Record Date. In the event of any taking by this
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or



Articles of Incorporation                                             Page 8
<PAGE>   9
property, or to receive any other right this Corporation shall mail to each
holder of Series A, Series B, Series C, Series D, Series E or Series F Preferred
Stock, at least 20 days prior to the date specified therein, a notice specifying
the date on which any such record is to be taken for the purpose of such
dividend, distribution or right and the amount and character of such dividend,
distribution or right.

                  (i) Reservation of Stock Issuable Upon Conversion. This
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock solely for the purpose of effecting the
conversion of the shares of the Series A, Series B, Series C, Series D, Series E
and Series F Preferred Stock such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
shares of the Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock; and if at any time the number of authorized but unissued shares
of Common Stock shall not be sufficient to effect the conversion of all then
outstanding shares of the Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock, in addition to such other remedies as shall be
available to the holder of such Preferred Stock, this Corporation will take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of Common Stock to such number of shares as
shall be sufficient for such purposes.

         5. Merger. Any notice required by the provisions of this Section 4 to
be given to the holders of shares of Series A, Series B, Series C, Series D,
Series E or Series F Preferred Stock shall be deemed given if deposited in the
United States mail, postage prepaid, and addressed to each holder of record at
his address appearing on the books of this Corporation.

                  (a) At any time, in the event of:

                           (i) any merger of the Corporation with or into any
other corporation in which the Corporation shall not be the continuing or
surviving entity of such merger or reorganization or any transaction or series
of related transactions by the Corporation in which in excess of 50% of the
Corporation's voting power is transferred, or

                           (ii) a sale of all or substantially all of the assets
of the Corporation, the documents effecting such transactions shall provide
that:

                                    (A) The holders of the Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock shall first receive
for each share of such stock, in cash or in securities received from the
acquiring Corporation, or in a combination thereof, at the closing of any such
transaction, an amount equal to the Original Series A, Series B, Series C,
Series D, Series E or Series F Issue Price, as the case may be, together with an
amount equal to all declared but unpaid dividends on each such share. If the
aggregate cash value in such transaction otherwise available to holders of the
Series A, Series B, Series C, Series D, Series E and Series F Preferred Stock is
insufficient to satisfy the aforementioned preference of the Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock, then all such cash or
securities shall be distributed ratably among the holders of the outstanding
Series A, Series B, Series C, Series D, Series E and Series F Preferred Stock in
proportion to the aggregate preferential amounts owed such holders as set forth
above.


Articles of Incorporation                                             Page 9
<PAGE>   10
                                    (B) After such distributions to the holders
of Series A, Series B, Series C, Series D and Series E Preferred Stock have been
paid, the remaining assets of the Corporation available for distribution to
shareholders shall be distributed among the holders of Common Stock pro rata,
based on the number of shares of Common Stock held by each.

                  (b) Any securities to be delivered to the holders of the
Series A, Series B, Series C, Series D, Series E and Series F Preferred Stock
pursuant to subsection 5(a) above shall be valued as follows:

                           (i) Securities not subject to investment letter or
other similar restrictions on free marketability:

                                    (A) If traded on a securities exchange, the
value shall be deemed to be the average of the closing prices of the securities
on such exchange over the 30-day period ending three (3) days prior to the
closing;

                                    (B) If actively traded over-the-counter, the
value shall be deemed to be the average of the closing bid prices over the
30-day period ending three (3) days prior to the closing; and

                                    (C) If there is no active public market, the
value shall be the fair market value thereof, as mutually determined by the
Corporation and the holders of not less than a majority of the then outstanding
shares of Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock.

                           (ii) The method of valuation of securities subject to
investment letter of other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in (i) (A),
(B) or (C) to reflect the approximate fair market value thereof, as mutually
determined by the Corporation and the holders of a majority of the then
outstanding shares of Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock.

                  (c) In the event the requirements of subsection 5(a) are not
complied with, the Corporation shall forthwith either:

                           (i) cause such closing to be postponed until such
time as the requirements of this Section 5 have been complied with, or (ii)
cancel such transaction, in which event the rights, preferences, privileges and
restrictions of the holders of the Series A, Series B, Series C, Series D,
Series E and Series F Preferred Stock shall revert to and be the same as such
rights, preferences, privileges and restrictions existing immediately prior to
the date of the first notice referred to in subsection 5(d) hereof.

                  (d) The Corporation shall give each holder of record of Series
A, Series B, Series C, Series D, Series E and Series F Preferred Stock written
notice of such impending transaction not later than twenty (20) days prior to
the shareholders' meeting called to approve such transaction, or twenty (20)
days prior to the closing of such transaction, whichever is earlier, and shall
also notify such holders in writing of the final approval of such transaction.
The first of such notices shall describe the 


Articles of Incorporation                                             Page 10
<PAGE>   11
material terms and conditions of the impending transaction and the provisions of
this Section 5, and the Corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the Corporation has given the first notice
provided for herein or sooner than ten (10) days after the Corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened upon the written consent of the holders of a majority
of the shares of Series A, Series B, Series C, Series D, Series E and Series F
Preferred Stock then outstanding.

                  (e) The provisions of this Section 5 are in addition to the
protective provisions of Section 7 hereof`

         6. Voting Rights. The holder of each share of Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock shall have the right
to one vote for each share of Common Stock into which such Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock could then be
converted (with any fractional share determined on an aggregate conversion basis
being rounded to the nearest whole share), and with respect to such vote, such
holder shall have full voting rights and powers equal to the voting rights and
powers of the holders of Common Stock, and shall be entitled, notwithstanding
any provision hereof, to notice of any shareholders' meeting in accordance with
the Bylaws of this Corporation, and shall be entitled to vote, together with
holders of Common Stock, with respect to any question upon which holders of
Common Stock have the right to vote.

         7. Protective Provisions. So long as shares of Series A, Series B,
Series C, Series D, Series E and Series F Preferred Stock are outstanding, this
Corporation shall not without first obtaining the approval (by vote or written
consent, as provided by law) of the holders of at least a majority of the then
outstanding shares of Series A, Series B, Series C, Series D, Series E and
Series F Preferred Stock, voting together as one class except where otherwise
required by law;

                  (a) sell, convey, or otherwise dispose of or encumber all or
substantially all of its property or business or merge into or consolidate with
any other Corporation (other than a wholly owned subsidiary Corporation) or
effect any transaction or series of related transactions in which more than 50%
of the voting power of the Corporation is disposed of;

                  (b) alter or change the rights, preferences, privileges or
restrictions of the shares of Series A, Series B, Series C, Series D, Series E
or Series F Preferred Stock so as to affect such shares adversely;

                  (c) increase the authorized number of shares of Series A,
Series B, Series C, Series D, Series E or Series F Preferred Stock; or

                  (d) create any new class or series of stock or any other
securities convertible into equity securities of the Corporation (i) having a
preference over, or being on a parity with, the Series A; Series B, Series C,
Series D, Series E or Series F Preferred Stock with respect to voting, dividends
or upon liquidation, or (ii) having rights similar to any of the rights of the

                            A California Corporation



                                   ARTICLE I

                                    OFFICES


         Section 1. PRINCIPAL OFFICES. The Board of Directors shall fix the
location of the principal executive office of the Corporation at any place
within or outside the State of California. If the principal executive office is
located outside this state, and the Corporation has one or more business offices
in this state, the Board of Directors shall fix and designate a principal
business office in the State of California.

         Section 2.  OTHER OFFICES.  The Board of Directors may at any
time establish branch or subordinate offices at any place or places
where the Corporation is qualified to do business.


                                   ARTICLE II

                            MEETING OF SHAREHOLDERS


         Section 1. PLACE OF MEETINGS. Meetings of the Shareholders shall be
held at any place within or outside of the State of California designated by the
Board of Directors. In the absence of any such designation, Shareholders'
meetings shall be held at the principal executive office of the Corporation.

         Section 2. ANNUAL MEETING. The annual meeting of Shareholders shall be
held on the second Tuesday of May in each year at 8:00 a.m. However, if this day
falls on a legal holiday, then the meeting shall be held at the same time and
place on the next succeeding full business day. At this meeting, directors shall
be elected, and any other proper business may be transacted.

         Section 3. SPECIAL MEETING. A special meeting of the Shareholders may
be called at any time by the Board of Directors, or by the Chairperson of the
Board, or by the President, or by one or more Shareholders holding shares in the
aggregate entitled to cast not less than 10% of the votes at that meeting.

                                        1
<PAGE>   2
         If a special meeting is called by any person or persons other than the
Board of Directors, the request shall be in writing, specifying the time of such
meeting and the general nature of the business proposed to be transacted, and
shall be delivered personally or sent by registered mail or by telegraphic or
other facsimile transmission to the Chairperson of the Board, the President, any
Vice President, or the Secretary of the Corporation. The officer receiving the
request shall cause notice to be promptly given to the Shareholders entitled to
vote, in accordance with the provisions of Sections 4 and 5 of this Article II,
that a meeting will be held at the time requested by the person or persons
calling the meeting, not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request. If the notice is not given within twenty
(20) days after receipt of the request, the person or persons requesting the
meeting may give the notice. Nothing contained in this paragraph of this Section
3 shall be construed as limiting, fixing or affecting the time when a meeting of
Shareholders called by action of the Board of Directors may be held.

         Section 4. NOTICE OF SHAREHOLDERS' MEETINGS. All notices of meetings of
Shareholders shall be sent or otherwise given in accordance with Section 5 of
this Article II not less than ten (10) nor more than sixty (60) days before the
date of the meeting. The notice shall specify the place, date and hour of the
meeting and (i) in the case of a special meeting, the general nature of the
business to be transacted, or (ii) in the case of the annual meeting, those
matters which the Board of Directors, at the time of giving the notice, intends
to present for action by the Shareholders. The notice of any meeting at which
Directors are to be elected shall include the name of any nominee or nominees
whom, at the time of the notice, management intends to present for election.

         If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a Director has a direct or indirect financial
interest, pursuant to Section 310 of the Corporations Code of California, (ii)
and amendment of the Articles of Incorporation, pursuant to Section 902 of that
Code, (iii) a reorganization of the Corporation, pursuant to Section 1201 of
that Code (iv) a voluntary dissolution of the Corporation, pursuant to Section
1900 of that Code, or (v) a distribution in dissolution other than in accordance
with the rights of outstanding preferred shares, pursuant to Section 1007 of
that Code, the notice shall also state the general nature of that proposal.

         Section 5. MANNER OF GIVING NOTICE: AFFIDAVIT OF NOTICE. Notice of any
meeting of Shareholders shall be given either personally or by first-class mail
or telegraphic or other written communication, charges pre-paid, addressed to
the Shareholder at the address of that Shareholder appearing on the books of the
Corporation or given by the Shareholder to the Corporation for the

                                       2
<PAGE>   3
purpose of notice. If no such address appears on the Corporation's books or is
given, notice shall be deemed to have been given if sent to that Shareholder by
first-class mail or telegraphic or other written communication to the
Corporation's principal executive office, or if published at least once in a
newspaper of general circulation in the county where that office is located.
Notice shall be deemed to have been given at the time when delivered personally
or deposited in the mail or sent by telegram or other means of written
communication.

         If any notice addressed to a Shareholder at the address of that
Shareholder appearing on the books of the Corporation is returned to the
Corporation by the United States Postal Service marked to indicate that the
United States Postal Service is unable to deliver the notice to the Shareholder
at that address, all future notices or reports shall be deemed to have been duly
given without further mailing if these shall be available to the Shareholder on
written demand of the Shareholder at the principal executive office of the
Corporation for a period of one year from the date of the giving of the notice.

         An affidavit of the mailing or other means of giving any notice of any
Shareholders' meeting shall be executed by the Secretary, Assistant Secretary,
or any transfer agent of the Corporation giving the notice, and shall be filed
and maintained in The Minute Book of the Corporation.

         Section 6. QUORUM. The presence in person or by proxy of the holders of
a majority of the shares entitled to vote at any meeting of Shareholders shall
constitute a quorum for the transaction of business. The Shareholders present at
a duly called or held meeting at which a quorum is present may continue to do
business until adjournment, notwithstanding the withdrawal of enough
Shareholders to leave less than a quorum, if any action taken (other than
adjournment) is approved by at least a majority of the shares required to
constitute a quorum.

         Section 7. ADJOURNED MEETING: NOTICE. Any Shareholders' meeting, annual
or special, whether or not a quorum is present, may be adjourned from time to
time by the vote of the majority of the shares represented at that meeting,
either in person or by proxy, but in the absence of a quorum, no other business
may be transacted at that meeting, except as provided in Section 6 of this
Article II.

         When any meeting of Shareholders, either annual or special, is
adjourned to another time or place, notice need not be given of the adjourned
meeting if the time and place are announced at a meeting at which the
adjournment is taken, unless a new record date for the adjourned meeting is
fixed, or unless the adjournment is for more than forty-five (45) days from the
date set for the original meeting, in which case the Board of Directors shall
set a new

                                       3
<PAGE>   4
record date. Notice of any such adjourned meeting shall be given to each
Shareholder of record entitled to vote at the adjourned meeting in accordance
with the provisions of Sections 4 and 5 of this Article II. At any adjourned
meeting the Corporation may transact any business which might have been
transacted at the original meeting.

         Section 8. VOTING. The Shareholders entitled to vote at any meeting of
the Shareholders shall be determined in accordance with the provisions of the
Corporations Code of California (relating to voting shares held by a fiduciary,
in the name of a Corporation, or in joint ownership). The Shareholders' vote may
be by voice vote or by ballot; provided, however, that any election for
Directors must be by ballot if demanded by any Shareholder before the voting has
begun. On any matter other than elections of Directors, any Shareholder may vote
part of the shares in favor of the proposal and refrain from voting the
remaining shares or vote them against the proposal, but if the Shareholder fails
to specify the number of shares which the Shareholder is voting affirmatively,
it will be conclusively presumed that the Shareholder's approving vote is with
respect to all shares that the Shareholder is entitled to vote. If a quorum is
present, the affirmative vote of the majority of the shares represented at the
meeting and entitled to vote on any matter (other than the election of
Directors) shall be the act of the Shareholders, unless the vote of a greater
number of voting by classes is required by California General Corporation Law or
by the Articles of Incorporation.

         At a Shareholders' meeting at which Directors are to be elected, no
Shareholder shall be entitled to cumulate votes (i.e., cast for any one or more
candidates a number of votes greater than the number of the Shareholder's
shares) unless the candidates' names have been placed in nomination prior to
commencement of the voting and a Shareholder has given notice prior to
commencement of the voting and a Shareholder has given notice prior to
commencement of the voting and a Shareholder has give notice prior to
commencement of the voting of the Shareholder's intention to cumulate votes. If
any Shareholder has given such a notice, then every Shareholder entitled to vote
may cumulate votes for candidates in nomination and give one candidate a number
of votes equal to the number of votes to which that Shareholder's shares are
entitled, or distribute the Shareholder's votes on the same principle among any
or all of the candidates as the Shareholder thinks fit. The candidates receiving
the highest number of votes, up to the number of Directors to be elected, shall
be elected.

         Section 9. WAIVER OF NOTICE OR CONSENT BY ABSENT SHAREHOLDERS. The
transactions of any meeting of Shareholders, either annual or special, however
called and noticed, and wherever held, shall be as valid as though there had
been a meeting duly held after regular call and notice, if a quorum be present
either in person or by proxy, and if, either before or after the meeting,

                                       4
<PAGE>   5
each person entitled to vote, who was not present in person or by proxy, signs a
written waiver of notice or a consent to a holding of the meeting or an approval
of the Minutes. The waiver of notice or consent need not specify either the
business to be transacted or the purpose of any annual or special meeting of the
Shareholders, except that if action is taken or proposed to be taken for
approval or any of those matters specified in the second paragraph of Section 4
of this Article II, the waiver of notice or consent shall state the .pa 
general nature of the proposal. All such waivers, consents, or approvals shall 
be filed with the corporate records or made a part of the Minutes of the 
meeting.

         Attendance by a person at a meeting shall also constitute a waiver of
notice of that meeting, except when the person objects, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened, and except that attendance at a meeting is not a waiver of
any right to object to the consideration of matters not included in the notice
of the meeting if that objection is expressly made at the meeting.

         Section 10. SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING.
Any action which may be taken at any annual or special meeting of Shareholders
may be taken without a meeting and without prior notice, if a consent in
writing, setting forth the action so taken is signed by the holders of
outstanding shares having not less than the minimum number of votes that would
be necessary to authorize or take that action at a meeting at which all shares
entitled to vote on that action were present and voted. In the case of election
of Directors, such a consent shall be effective only if signed by the holders of
all outstanding shares entitled to vote for the election of Directors; provided,
however, that a Director may be elected at any time to fill a vacancy on the
Board of Directors that has not been filled by the Directors, by the written
consent of the holders of a majority of the outstanding shares entitled to vote
for the election of Directors. All such consents shall be filed with the
Secretary of the Corporation and shall be maintained in the corporate records.
Any Shareholder giving a written consent, or the Shareholder's proxy holders, or
a transferee of the shares or a personal representative of the Shareholder or
their respective proxy holders or a transferee of the shares or personal
representative, may revoke the consent by a writing received by the Secretary of
the Corporation before written consents of the number of shares required to
authorize the proposed action have been filed with the Secretary.

         If the consents of all Shareholders entitled to vote have not been
solicited in writing, and if the unanimous written consent of all such
Shareholders shall not have been received, the Secretary shall give prompt
notice of the corporate action approved by the Shareholders without a meeting.
This notice shall be given in the manner specified in Section 5 of this Article
II. In the case of

                                       5
<PAGE>   6
approval of (i) contracts or transactions in which a Director has a direct or
indirect financial interest, pursuant to Section 310 of the Corporations Code of
California, (ii) indemnification of agents of the corporation, pursuant to
Section 317 of that Code, (iii) a reorganization of the Corporation, pursuant to
Section 1201 of that Code, and (iv) a distribution in dissolution other than in
accordance with the rights of outstanding preferred shares, pursuant to Section
2007 of that Code, the notice shall be given at least ten (10) days before the
consummation of any action authorized by that approval.

         Section 11. RECORD DATE FOR SHAREHOLDER NOTICE, VOTING, AND GIVING
CONSENTS. For purposes of determining the Shareholders entitled to notice of any
meeting or to vote or entitled to give consent to corporate action without a
meeting, the Board of Directors may fix, in advance, a record date, which shall
not be more that sixty (60) days nor less than ten (10) days before the date of
any such meeting nor more than sixty (60) days before any such action without a
meeting, and in this event only Shareholders of record on the date so fixed are
entitled to notice and to vote or to give consent, as the case may be,
notwithstanding any transfer of shares on the books of the Corporation after the
record date, except as otherwise provided in the California General Corporation
Law.

         If the Board of Directors does not so fix a record date:

         (a) The record date for determining Shareholders entitled to a notice
of or to vote at a meeting of Shareholders shall be at the close of business on
the business day next preceding the day of which notice is given or, if notice
is waived, at the close of business on the business day next preceding the day
on which the meeting is held.

         (b) The record date for determining Shareholders entitled to give
consent to corporate action in writing without a meeting, (i) when no prior
action by the Board has been taken, shall be the day on which the first written
consent is given, or (ii) when prior action of the Board has been taken, shall
be at the close of business on the day on which the Board adopts the resolution
relating to that action, or the sixtieth (60th) day before the date of such
other action, whichever is later.

         Section 12. PROXIES. Every person entitled to vote for Directors or on
any other matter shall have the right to do so either in person or by one or
more agents authorized by a written proxy signed by the person and filed with
the Secretary of the Corporation. A proxy shall be deemed signed if the
Shareholder's name is placed on the proxy (whether by manual signature,
typewriting, telegraphic transmission, or otherwise) by the Shareholder or the
Shareholder's attorney in fact. A validly executed proxy which does not state
that it is irrevocable shall

                                       6
<PAGE>   7
continue in full force and effect unless (i) revoked by the person executing it,
before the vote pursuant to that proxy, by a writing delivered to the
Corporation stating that attendance at the meeting and voting in person by the
person executing the proxy; or (ii) written notice of the death or incapacity of
the maker of the proxy is received by the Corporation before the vote pursuant
to that proxy is counted; provided, however, that no proxy shall be valid after
the expiration of eleven (11) months from the date of the proxy, unless
otherwise provided in the proxy. The revocability of a proxy that states on its
facts that it is irrevocable shall be governed by the provisions of the
Corporations Code of California.

         Section 13. INSPECTORS OF ELECTION. Before any meeting of Shareholders,
the Board of Directors may appoint any persons other than nominees for office to
act as inspectors of election at the meeting or its adjournment. If no
inspectors of election are so appointed, the Chairperson of the meeting may, and
on the request of any Shareholder or a Shareholder's proxy shall, appoint
inspectors at the meeting. The number of inspectors shall be either one (1) or
three (3). If inspectors are appointed at a meeting on the request of one or
more Shareholders or proxies, the holders of a majority of shares or their
proxies present at the meeting shall determine whether one (1) or three (3)
inspectors are to be appointed. If any person appointed as inspector fails to
appear or fails or refuses to act, the Chairperson of the meeting may, and upon
the request of any Shareholder or Shareholder's proxy shall, appoint a person to
fill that vacancy.

         These inspectors shall:

         (a)      Determine the number of shares outstanding and the voting
                  power of each, the share represented at the meeting, the
                  existence of a quorum, and the authenticity, validity, and
                  effect of proxies;

         (b)      Receive votes, ballots, or consents;

         (c)      Hear and determine all challenges and questions in any way
                  arising in connection with the right to vote;

         (d)      Count and tabulate all votes or consents;

         (e)      Determine when the polls shall close;

         (f)      Determine the result; and

         (g)      Do any other acts that may be proper to conduct the election
                  or vote with fairness to all Shareholders.

                                  ARTICLE III

                                   DIRECTORS


         Section 1. POWERS. Subject to the provisions of the California General
Corporation Law and any limitations in the Articles of Incorporation and these
Bylaws relating to action required to be approved by the Shareholders or by the
outstanding shares, the business and affairs of the Corporation shall be managed
and all corporate powers shall be exercised by or under the direction of the
Board of Directors.

         Without prejudice to these general powers, and subject to the same
limitations, the directors shall have the power to:

                  (a) Select and remove all officers, agents, and employees of
the corporation; prescribe any powers and duties for them that are consistent
with law, with the articles of incorporation, and with these bylaws; fix their
compensation; and require from them security for faithful service.

                  (b) Change the principal executive office or the principal
business office in the State of California from one location to another; cause
the corporation to be qualified to do business in any other state, territory,
dependency, or country and conduct business within or without the State of
California; and designate any place within or without the State of California

         Section 4. CERTIFICATES FOR SHARES. A certificate or certificates for
shares of the capital stock of the Corporation shall be issued to each
Shareholder when any of these shares are fully paid, and the Board of Directors
may authorize the issuance of certificates or shares as partly paid provided
that these certificates shall state the amount of the consideration to be paid
for them and the amount paid. All certificates shall be signed in the name of
the Corporation by the Chairperson of the Board or Vice Chairperson of the Board
or the President or Treasurer or the Secretary or any Assistant Secretary,
certifying the number of shares and the class or series of shares owned by the
Shareholder. Any or all of the signatures on the certificates may be facsimiles.

<PAGE>   20
whose facsimile signature has been placed on a certificate shall have ceased to
be that officer, transfer agent, or registrar before that certificate is issued,
it may be issued by the Corporation with the same effect as if that person were
an officer, transfer agent, or registrar at the date of issue.

         Section 5. LOST CERTIFICATES. Except as provided in this Section 5, no
new certificates for shares shall be issued to replace an old certificate unless
the latter is surrendered to the Corporation and cancelled at the same time. The
Board of Directors may, in case any share certificate or certificate for any
other security is lost, stolen, or destroyed, authorize the issuance of a
replacement certificate on such terms and conditions as the Board may require,
including provision for indemnification of the Corporation secured by a bond or
other adequate security sufficient to protect the Corporation against any claim
that may be made against it, including any expenses or liability, on account of
the alleged loss, theft, or destruction of the certificate or the issuance of
the replacement certificate.

         Section 6. REPRESENTATION OF SHARES OF OTHER CORPORATIONS. The
Chairperson of the Board, the President, or any Vice President, or any other
person authorized by resolution of the Board of Directors or by any of the
foregoing designated officers, is authorized to vote on behalf of the
Corporation any and all shares of any other Corporation or Corporations, foreign
or domestic, standing in the name of the Corporation. The authority granted to
these officers to vote or represent on behalf of the Corporation any and all
shares held by the Corporation in any other Corporation or Corporations may be
exercised by any of these officers in person or by any person authorized to do
so by a proxy duly executed by these officers.

         Section 7. CONSTRUCTION AND DEFINITIONS. Unless the context requires
otherwise, the general provisions, rules and construction, and definitions in
the California General Corporation Law shall govern the construction of these
Bylaws. Without limiting the generality of this provision, the singular number

                           WARRANT TO PURCHASE SHARES
                         OF SERIES E PREFERRED STOCK OF

                         U.S. MEDICAL INSTRUMENTS, INC.



         1. NUMBER AND PRICE OF SHARES SUBJECT TO WARRANT. Subject to the terms
and conditions herein set forth, G.C. Investments, L.L.C. (the "Purchaser") or
its assignee(s) in accordance with the terms hereof, is entitled to purchase

any time until January 31, 1998, One Hundred Six Thousand Six Hundred Sixty

described below) of fully paid and nonassessable shares of Series E Preferred
Stock ("Stock") of the Company upon surrender hereof at the principal office of
the Company and, at the election of the holder hereof, upon either payment of
the purchase price at said office in cash or by check or the cancellation of any
present or future indebtedness from the Company to the holder hereof in a dollar
amount equal to the purchase price of the Stock for which the consideration is
being given. Subject to adjustment as hereinafter provided, the purchase price
of one share of Stock (or such securities as may be substituted for one share of
Stock pursuant to the provisions hereinafter set forth), referred to herein as
the "Warrant Price", is $7.50.

         2. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number and
kind of securities issuable upon the exercise of this Warrant shall be subject
to adjustment from time to time upon the happening of certain events as follows:

                  (a) ADJUSTMENT FOR DIVIDENDS IN STOCK OR OTHER SECURITIES OR
PROPERTY. In case at any time or from time to time on or after the date hereof
the holders of the Stock of the Company (or any shares of stock or other
securities at the time receivable upon the exercise of this Warrant) shall have
received, or, on or after the record date fixed from the determination of
eligible shareholders, shall have become entitled to receive, without payment
therefor, other or additional stock or other securities or property (including
cash) of the Company by way of dividend, then and in each case, the holder of
this Warrant shall, upon the exercise hereof, be entitled to receive, in
addition to the number of shares of Stock receivable thereupon, and without
payment of any additional consideration therefor, the amount of such other or
additional stock or other securities or property (including cash) of the Company
which such holder would hold on the date of such exercise had it been the holder
of record of Such Stock on the date hereof and had thereafter, during the period
from the date hereof to and including the date of such exercise, retained such
shares and/or all other additional stock available by it as aforesaid during
such period, giving effect to all adjustments called for during such period by
paragraphs (b) and (c) of this paragraph 2.
<PAGE>   2
Where   X =     the number of shares of Stock to be issued to the Purchaser,

        Y =     the number of shares of Stock purchasable under the Warrant or,
                if only a portion of the Warrant is being exercised, the portion
                of the Warrant being canceled (at the date of such calculation),

        A =     the fair market value of one share of the Company's Stock (at
                the date of such calculation), and

        B =     the Warrant Price (as adjusted to the date of such calculation).

        For purposes of the above calculation, fair market value of one share of
Stock shall be determined by the Company's Board of Directors in good faith;
provided, however, that where there exists a public market for the Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty (20) trading days (or such fewer number of days as such public
market has existed) of the mean of the high closing bid and asked prices on the
over-the-counter market as reported by Nasdaq, or if then traded on a national
securities exchange or the Nasdaq National Market, the average over the
preceding twenty (20) trading days (or such fewer number of days as the Stock
has been so traded) of the mean of the high and low prices on the principal
national securities exchange or the National Market on which it is so traded.

        7. TERM OF WARRANT. This Warrant expires and shall no longer be
exercisable as of 11:59 p.m. Pacific standard time, January 31, 1998, and shall
be void thereafter.

        8. CERTIFICATE OF ADJUSTMENT. Whenever the Warrant Price or number or
type of securities issuable upon exercise of this Warrant is adjusted, as herein
provided. the Company shall promptly deliver to the record holder of this
Warrant a certificate of an officer of the Company setting forth the nature of
such adjustment and a brief statement of the facts requiring such adjustment.

        9. TRANSFER OF WARRANT. This Warrant may be freely transferred or
assigned by the Purchaser in whole or in part, subject to compliance with all
federal and state securities laws by the transferor and the transferee.

        10. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction of any Warrant,
on delivery of an indemnity agreement or security reasonably satisfactory in
form and amount to the Company or, in the case of any such mutilation, on
surrender and cancellation of such Warrant, the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

acceptance hereof, acknowledges that this Warrant and the shares of Series E
Preferred Stock to be issued upon exercise hereof are being acquired solely for
the Purchaser's own account and not as a nominee for any other party, and (or
investment, and that the Purchaser will not offer, sell or otherwise dispose of

      THEREFROM UNDER SAID ACT. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF
      THESE SECURITIES AND RESTRICTING THEIR TRANSFER OF SALE MAY BE OBTAINED AT
      NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD HEREOF TO THE

and conditions herein set forth, _____________ (the "Purchaser") is entitled to
purchase from the Company, at any time until November 30, 1998, ______________
(_____) shares (which number of shares is subject to adjustment as described
below) of fully paid and non assessable Common Stock ("Common Stock") of the
Company upon surrender hereof at the principal office of the Company and, at the
election of the holder hereof, upon either payment of the purchase price at said
office in cash or by check or the cancellation of any present or future
indebtedness from the Company to the holder hereof in a dollar amount equal to
the purchase price of the Common Stock for which the consideration is being
given. Subject to adjustment as hereinafter provided, the purchase price of one
share of Common Stock (or such securities as may be substituted for one share of
Common Stock pursuant to the provisions hereinafter set forth), referred to
herein as the "Warrant Price", is $1.50.

        2. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number and kind
of securities issuable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as follows:

                (a) Adjustment for Dividends in Stock or Other Securities or
Property. In case at any time or from time to time on or after the date hereof
the holders of the Common Stock of the Company (or any shares of stock or other
securities at the time receivable upon the exercise of this Warrant) shall have
received, or, on or after the record date fixed from the determination of
eligible shareholders, shall have become entitled to receive, without payment
therefor, other or additional stock or other securities or property (other than
cash) of the Company by way of dividend, then and in each case, the holder of
this Warrant shall, upon the exercise hereof, be entitled to receive, in
addition to the number of shares of Common Stock receivable thereupon, and
without payment of any additional consideration therefor, the amount of such
other or additional stock or other securities of r property (other than cash) of
the Company which such holder would hold on the date of such exercise had it
been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock available
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this paragraph 2.

                (b) Adjustment for Reclassification, Reorganization or Merger.
In case of any reclassification or change of the outstanding securities of the
Company or of any reorganization of the Company (or any other corporation the
stock or securities of which are at the time receivable upon the exercise of
this Warrant) or any similar corporate reorganization on or after the date
hereof, then and in each such case the holder of this Warrant, upon the exercise
hereof at any time after the consummation of such reclassification, change,
reorganization, merger or conveyance, shall be entitled to receive, in lieu of
the stock or other securities and property receivable upon the exercise hereof
prior to such consummation, the stock or other securities or property to which
such holder would have been entitled upon such consummation if such holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in paragraphs (a) and (c); and in each such case, the
terms of this paragraph 2 shall be applicable
<PAGE>   2
to the shares of stock or other securities properly receivable upon the exercise
of this Warrant after such consummation.

                (c) Stock Splits and Reverse Stock Splits. If at any time on or
after the date hereof the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of the Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of Warrant shall thereby be proportionately
decreased.

                (d) Conversion or Redemption of Common Stock. If at the time of
any exercise of this Warrant there are no other shares of Common Stock
outstanding (such shares having been converted or redeemed), this Warrant shall
be exercisable for Common Stock instead of Common Stock in the same amounts, for
the same prices and on the same terms, and all references herein to "Common
Stock" shall be changed to refer to "Common Stock."

        3. NO FRACTIONAL SHARES. No fractional shares of Common Stock will be
issued in connection with any subscription hereunder. In lieu of any fractional
shares which would otherwise be issuable, the Company shall pay cash equal to
the product of such fraction multiplied by the fair market value of one share of
Common Stock on the date of exercise, as determined in good faith by the
Company's Board of Directors.

        4. NO SHAREHOLDER RIGHTS. This Warrant shall not entitle its holder to
any of the rights of a shareholder of the Company.

        5. RESERVATION OF STOCK. The Company covenants that during the period
this Warrant is exercisable, the Company will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of Common Stock upon the exercise of this Warrant. The Company agrees that its
issuance of this Warrant shall constitute full authority to its officers who are
charged with the duty of executing stock certificates to execute and issue the
necessary certificates for shares of Common Stock upon the exercise of this
Warrant.

        6. EXERCISE OF WARRANT. This Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant and the Notice of
Exercise attached hereto as Exhibit A duly completed and executed on behalf of
the holder hereof, at the principal office of the Company, accompanied by
payment in full of the Warrant Price then in effect as described above. This
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of its surrender for exercise as provided above, and the
person entitled to receive the shares of Common Stock issuable upon such
exercise shall be treated for all purposes as the holder of such shares of
record as of the close of business on such date. As promptly as practicable on
or after such date and in any event within ten (10) days thereafter, the Company
at its expense shall issue and deliver to the person or persons entitled to
receive the same a certificate or certificates for the number of full shares of
Common Stock issuable upon such exercise, together with cash in lieu of any
fraction of a share as provided above. The shares of Common Stock issuable upon
exercise hereof shall, upon their issuance, be fully paid and non assessable. In
the event that this Warrant is
<PAGE>   3
exercised in part, the Company at its expense will execute and deliver a new
Warrant of like tenor exercisable for the number of shares for which this
Warrant may then be exercised.

        7. CERTIFICATE OF ADJUSTMENT. Whenever the Warrant Price or number or
type of securities issuable upon exercise of this Warrant is adjusted, as herein
provided, the Company shall promptly deliver to the record holder of this
Warrant a certificate of an officer of the Company setting forth the nature of
such adjustment and a brief statement of the facts requiring such adjustment.

        8. TRANSFER OF WARRANT. This Warrant may be freely transferred or
assigned by the Purchaser in whole or in part, subject to compliance with all
federal and state securities laws by the transferor and the transferee.

        9. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction of any Warrant,
on delivery of an indemnity agreement or security reasonably satisfactory in
form and amount to the Company or, in the case of any such mutilation, on
surrender and cancellation of such Warrant, the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

        10. MISCELLANEOUS. This Warrant shall be governed by the laws of the
State of California. The heading in this Warrant are for purposes of convenience
and reference only, and shall not be deemed to constitute a part hereof. Neither
this Warrant nor any term hereof may be changed, waived, discharged or
terminated orally but only be an instrument in writing signed by the Company and
the registered holder hereof. All notices and other communications from the
Company to the holder of this Warrant shall be mailed by first class registered
or certified mail, postage prepaid, to the address furnished to the Company in
writing by the last holder of this Warrant who shall have furnished an address
to the Company in writing. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provisions.

        11. TERMINATION. This Warrant (and the right to purchase securities upon
exercise hereof) shall terminate on November 30, 1998.

election of the holder hereof, upon either payment of the purchase price at said
office by bank certified or cashier's check or by wire of immediately available
funds. Subject to adjustment as hereinafter provided, the purchase price of one
share of Stock (or such securities as may be substituted for one share of Stock
pursuant to the provisions hereinafter set forth), referred to herein as the
"Warrant Price", is $14.00.

        2. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number and kind
of securities issuable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as follows:

                (a) ADJUSTMENT FOR DIVIDENDS IN STOCK OR OTHER SECURITIES OR
PROPERTY. In case at any time or from time to time on or after the date hereof
the holders of the Stock of the Company (or any shares of stock or other
securities at the time receivable upon the exercise of this Warrant) shall have
received, or, on or after the record date fixed from the determination of
eligible shareholders, shall have become entitled to receive, without payment
therefor, other or additional stock or other securities or property (including
cash) of the Company by way of dividend, then and in each case, the holder of
this Warrant shall, upon the exercise hereof, be entitled to receive, in
addition to the number of shares of Stock receivable thereupon, and without
payment of any additional consideration therefor, the amount of such dividend
had it been the holder of record of such Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock available
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this paragraph 2.

                (b) ADJUSTMENT FOR RECLASSIFICATION, REORGANIZATION OR MERGER.
In case of any reclassification or change of the outstanding securities of the
Company or of any reorganization of the Company (or any other corporation the
stock or securities of which are at the time receivable upon the exercise of
this Warrant) or any similar corporate reorganization on or after the date
hereof, then and in each such case the holder of this Warrant, upon the exercise
hereof at any time after the consummation of such reclassification, change,
reorganization, merger or conveyance, shall be entitled to receive, in lieu of
the Stock or other securities and property receivable upon the exercise hereof
prior to such consummation, the stock or other securities or property to which
such holder would have been entitled upon such consummation if such holder had
exercised this Warrant immediately prior thereto, all subject to further
adjustment as provided in paragraphs (a) and (c); and in each such case, the
terms of this paragraph 2 shall be applicable to the shares of stock or other
securities properly receivable upon the exercise of this Warrant after such
consummation.

                (c) STOCK SPLITS AND REVERSE STOCK SPLITS. If at any time on or
after the date hereof the Company shall subdivide its outstanding shares of
Stock into a greater number of shares, the Warrant Price in effect immediately
prior to such subdivision shall thereby be proportionately reduced and the
number of shares receivable upon exercise of the Warrant shall thereby be
proportionately increased; and, conversely, if at any time on or after the date
hereof the outstanding number of shares of Stock shall be combined into a
smaller number of shares, the Warrant Price in effect immediately prior to such
combination shall thereby proportionately increased and the number of shares
receivable upon exercise of Warrant shall thereby be proportionately decreased.

                (d) NOTICE OF ADJUSTMENT. When any adjustment is required to be
made in the number or kind of shares purchasable upon exercise of the Warrant,
or in the Warrant Price, the Company shall promptly notify the Purchaser of such
event and of the number of shares of Stock or other securities or property
thereafter purchasable upon exercise of the Warrant.

        3. NO FRACTIONAL SHARES. No fractional shares of Stock will be issued in
connection with any subscription hereunder. In lieu of any fractional shares
which would otherwise be issuable, the Company shall pay cash equal to the
product of such fraction multiplied by the fair market value of one share of
Stock on the date of exercise, as determined in good faith by the Company's
Board of Directors.

        4. NO SHAREHOLDER RIGHTS. This Warrant shall not entitle its holder or
any of the rights of a shareholder of the Company.

        5. RESERVATION OF STOCK. The Company covenants that during the period
this Warrant is exercisable, the Company will reserve from its authorized and
unissued Stock a sufficient number of shares to provide for the issuance of
Stock upon the exercise of this Warrant. The Company agrees that its issuance of
this Warrant shall constitute full authority to its officers who are charged
with the duty of executing stock certificates to execute and issue the necessary
certificates for shares of Stock upon the exercise of this Warrant.

        6. EXERCISE OF WARRANT. This Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant and the Notice of
Exercise attached hereto as Exhibit A duly completed and executed on behalf of
the holder hereof, at the principal office of the Company, accompanied by
payment in full of the Warrant Price then in effect as described above. This
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of its surrender for exercise as provided above, and the
person entitled to receive the shares of Stock issuable upon such exercise shall
be treated for all purposes as the holder of such shares of record as of the
close of business on such date and in any event within ten (10) days thereafter,
the Company at its expense shall issue and deliver to the person or persons
entitled to receive the same a certificate or certificates for the number of
full shares of Stock issuable upon such exercise, together with cash in lieu of
any fraction of a share as provided above. The shares of Stock issuable upon
exercise hereof shall, upon their issuance, be fully paid and nonassessable. In
the event that this Warrant is exercised in part, the Company at its expense
will execute and deliver a new Warrant of like tenor exercisable for the number
of shares for which this Warrant may then be exercised.

                (a) NET ISSUE EXERCISE. Notwithstanding any provisions herein to
the contrary, in lieu of exercising this Warrant for cash, the Purchaser may
elect to receive shares equal to the value (as determined below) of this Warrant
or the portion thereof being canceled) by surrender of this Warrant at the
principal office of the Company together with a properly endorsed notice of
<PAGE>   3
exercise and notice of such election in which event the Company shall issue to
Purchaser a number of shares of Stock computed using the following formula:

                                 X = Y(A-B)
                                     ------
                                        A

Where   X =     the number of shares of Stock to he issued to the Purchaser,

        Y =     the number of shares of Stock purchasable under the Warrant or,
                if only a portion of the Warrant is being exercised, the portion
                of the Warrant being canceled (at the date of such calculation),

        A =     the fair market value of one share of the Company's Stock at the
                date of such calculation), and

        B =     the Warrant Price (as adjusted to the date of such calculation).

        For purposes of the above calculation, fair market value of one share of
Stock shall be determined by the Company's Board of Directors in good faith;
provided, however, that where there exists a public market for the Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty (20) trading days (or such fewer number of days as such public
market has existed) of the mean of the high closing bid and asked prices on the
over-the- counter market as reported by NASDAQ, or if then traded on a national
securities exchange or the NASDAQ National Market, the average over the
preceding twenty (20) trading days (or such fewer number of days as the Stock
has been so traded) of the mean of the high and low prices on the principal
national securities exchange or the National Market on which it is so traded.

        7. TERM OF WARRANT. This Warrant expires and shall no longer be
exercisable as of 11:59 p.m. Pacific Standard Time, December 31, 1997 and shall
be void thereafter.

        8. CERTIFICATE OF ADJUSTMENT. Whenever the Warrant Price or number or
type of securities unissuable upon exercise of this Warrant is adjusted, as
herein provided, the Company shall promptly deliver to the record holder of this
Warrant a certificate of an officer of the Company setting forth the nature of
such adjustment and a brief statement of the facts requiring such adjustment.

        9. TRANSFER OF WARRANT. This Warrant may be freely transferred or
assigned by the Purchaser in whole or in part, subject to compliance with all
federal and state securities laws by the transferor and the transferee.

        10. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction of any Warrant,
on delivery of an indemnity agreement or security reasonably satisfactory in
form and amount to the Company or, in the case of any such mutilation, on
surrender and cancellation of such Warrant, the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

acceptance hereof, acknowledges that this Warrant and the shares of Common Stock
to be issued upon exercise hereof are being acquired solely for the Purchaser's

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. THEY
MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN
EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID ACT OR AN
OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT

                       WARRANT TO PURCHASE 223,000 SHARES

                         U.S. MEDICAL INSTRUMENTS, INC.

        1. NUMBER AND PRICE OF SHARES SUBJECT TO WARRANT. Subject to the terms
and conditions herein set forth, Robert C. Siegel and Doris Siegel UDT dated
August 19, 1976 wherein Robert Siegel and Doris Siegel are trustees, or any
successor thereunder (the "Purchaser") is entitled to purchase from U.S. Medical
Instruments, Inc., a California Corporation (the "Company"), at any time for the
period of five (5) years from the date of the First Claim, Two Hundred Twenty
Three Thousand (223,000) shares (which number of shares is subject to adjustment
as described below) of fully paid and non assessable Common Stock ("Common
Stock") of the Company upon surrender hereof at the principal office of the
Company and, at the election of the holder hereof, upon either payment of the
purchase price at said office in cash or by check or the cancellation of any
present or future indebtedness from the Company to the holder in a First Claim
equal to the purchase price of the Common Stock for which the consideration is
being given. Subject to adjustment as hereinafter provided, the purchase price
of one share of Common Stock (or such securities as may be substituted for one
share of Common Stock pursuant to the provisions hereinafter set forth), shall
be $8.00. The purchase price of one share of Common Stock (or such securities as
may be substituted for one share of Common Stock pursuant to the provisions
hereinafter set forth) payable from time to time upon the exercise of this
Warrant.

        2. ADJUSTMENT OF WARRANT PRICE AND NUMBER OF SHARES. The number and kind
of securities issuable upon the exercise of this Warrant shall be subject to
adjustment from time to time upon the happening of certain events as follows:

                (a) Adjustment for Dividends in Stock or Other Securities or
Property. In case at any time or from time to time on or after the date hereof
the holders of the Common Stock of the Company (or any shares of stock or other
securities at the time receivable upon the exercise of this Warrant) shall have
received, or, on or after the record date fixed from the determination of
eligible shareholders, shall have become entitled to receive, without payment
therefor, other or additional stock or other securities or property (other than
cash) of the Company by way of dividend, then and in each case, the holder of
this Warrant shall, upon the exercise hereof, be entitled to receive, in
addition to the number of shares of Common Stock receivable thereupon, and
without payment of any additional consideration therefor, the First Claim Holder
of such other or additional stock or other securities or property (other than
cash) of the Company which such holder would hold on the date of such exercise
had it been the holder of record of such Common Stock on the date hereof and had
thereafter, during the period from the date hereof to and including the date of
such exercise, retained such shares and/or all other additional stock available
by it as aforesaid during such period, giving effect to all adjustments called
for during such period by paragraphs (b) and (c) of this paragraph 2.

                (b) Adjustment for Reclassification, Reorganization or Merger.
In case of any reclassification or change of the outstanding securities of the
Company or of any reorganization of the Company (or any other corporation the
stock or securities of which are at the





                                       1
<PAGE>   2
time receivable upon the exercise of this Warrant) or any similar corporate
reorganization on or after the date hereof, then and in each such case the
holder of this Warrant, upon the exercise hereof at any time after the
consummation of such reclassification, change, reorganization, merger or
conveyance, shall be entitled to receive, in lieu of the stock or other
securities and property receivable upon the exercise hereof prior to such
consummation, the stock or other securities or property to which such holder
would have been entitled upon such consummation if such holder had exercised
this Warrant immediately prior thereto, all subject to further adjustment as
provided in paragraphs (a) and (c); and in each such case, the terms of this
paragraph 2 shall be applicable to the shares of stock or other securities
properly receivable upon the exercise of this Warrant after such consummation.

                (c) Stock Splits and Reverse Stock Splits. If at any time on or
after the date hereof the Company shall subdivide its outstanding shares of
Common Stock into a greater number of shares, the Warrant Price in effect
immediately prior to such subdivision shall thereby be proportionately reduced
and the number of shares receivable upon exercise of the Warrant shall thereby
be proportionately increased; and, conversely, if at any time on or after the
date hereof the outstanding number of shares of Common Stock shall be combined
into a smaller number of shares, the Warrant Price in effect immediately prior
to such combination shall thereby be proportionately increased and the number of
shares receivable upon exercise of Warrant shall thereby be proportionately
decreased.

                (d) Conversion or Redemption of Common Stock. If at the time of
any exercise of this Warrant there are no other shares of Common Stock
outstanding (such shares having been converted or redeemed), this Warrant shall
be exercisable for Common Stock, for the same prices and on the same terms, and
all references herein to "Common Stock" shall be changed to refer to "Common
Stock."

        3. FRACTIONAL SHARES. Fractional shares of Common Stock will be issued
in connection with any subscription hereunder. In lieu of any fractional shares
which would otherwise be issuable, the Company shall pay cash equal to the
product of such fraction multiplied by the fair market value of one share of
Common Stock on the date of exercise, as determined in good faith by the
Company's Board of Directors.

        4. NO SHAREHOLDER RIGHTS. This Warrant shall not entitle its holder to
any of the rights of a shareholder of the Company.

        5. RESERVATION OF STOCK. The Company covenants that during the period
this Warrant is exercisable, the Company will reserve from its authorized and
unissued Common Stock a sufficient number of shares to provide for the issuance
of Common Stock upon the exercise of this Warrant. The Company agrees that its
issuance of this Warrant shall constitute full authority to its officers who are
charged with the duty of executing stock certificates to execute and issue the
necessary certificates for shares of Common Stock upon the exercise of this
Warrant.

        6. EXERCISE OF WARRANT. This Warrant may be exercised by the holder
hereof, in whole or in part, by the surrender of this Warrant and the Notice of
Exercise attached hereto as Exhibit A duly completed and executed on behalf of
the holder hereof, at the principal office of the Company, accompanied by
payment in full of the Warrant Price then in effect as described above. This
Warrant shall be deemed to have been exercised immediately prior to the close of
business on the date of its surrender for exercise as provided above, and the
person entitled to receive the shares of Common Stock issuable upon such
exercise shall be treated for all purposes as the holder of such shares of
record as of the close of business on such date. As promptly as practicable on
or after such date and in any event within ten (10) days thereafter, the Company
at its expense shall


                                       2
<PAGE>   3
issue and deliver to the person or persons entitled to receive the same a
certificate or certificates for the number of full shares of Common Stock
issuable upon such exercise, together with cash in lieu of any fraction of a
share as provided above. The shares of Common Stock issuable upon exercise
hereof shall, upon their issuance, be fully paid and non assessable. In the
event that this Warrant is exercised in part, the Company at its expense will
execute and deliver a new Warrant of like tenor exercisable for the number of
shares for which this Warrant may then be exercised.

                (a) NET ISSUE EXERCISE. Notwithstanding any provisions herein to
the contrary, in lieu of exercising this Warrant for cash, the Purchaser may
elect to receive shares equal to the value (as determined below) of this Warrant
or the portion thereof being canceled) by surrender of this Warrant at the
principal office of the Company together with a properly endorsed notice of
exercise and notice of such election in which event the Company shall issue to
Purchaser a number of shares of Stock computed using the following formula:

                                         X = Y(A-B)
                                             ------
                                                A

Where   X =     the number of shares of Stock to be issued to the Purchaser,

        Y =     the number of shares of Stock purchasable under the Warrant or,
                if only a portion of the Warrant is being exercised, the portion
                of the Warrant being canceled (at the date of such calculation),

        A =     the fair market value of one share of the Company's Stock at the
                date of such calculation), and

        B =     the Warrant Price (as adjusted to the date of such calculation).

        For purposes of the above calculation, fair market value of one share of
Stock shall be determined by the Company's Board of Directors in good faith;
provided, however, that where there exists a public market for the Stock at the
time of such exercise, fair market value shall mean the average over the
preceding twenty (20) trading days (or such fewer number of days as such public
market has existed) of the mean of the high closing bid and asked prices on the
over-the- counter market as reported by NASDAQ, or if then traded on a national
securities exchange or the NASDAQ National Market, the average over the
preceding twenty (20) trading days (or such fewer number of days as the Stock
has been so traded) of the mean of the high and low prices on the principal
national securities exchange or the National Market on which it is so traded.

        7. CERTIFICATE OF ADJUSTMENT. Whenever the Warrant Price or number or
type of securities issuable upon exercise of this Warrant is adjusted, as herein
provided, the Company shall promptly deliver to the record holder of this
Warrant a certificate of an officer of the Company setting forth the nature of
such adjustment and a brief statement of the facts requiring such adjustment.

        8. TRANSFER OF WARRANT. This Warrant may be freely transferred or
assigned by the Purchaser in whole or in part, subject to compliance with all
federal and state securities laws by the transferor and the transferee.

        9. REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of any
Warrant and, in the case of any such loss, theft or destruction of any Warrant,
on delivery of an indemnity agreement or security



                                       3
<PAGE>   4
reasonably satisfactory in form from the Holder to the Company or, in the case
of any such mutilation, on surrender and cancellation of such Warrant, the
Company at its expense will execute and deliver, in lieu thereof, a new Warrant
of like tenor.

        10. MISCELLANEOUS. This Warrant shall be governed by the laws of the
State of California. The heading in this Warrant arc for purposes of convenience
and reference only, and shall not be deemed to constitute a part hereof. Neither
this Warrant nor any term hereof may be changed, waived, discharged or
terminated orally but only be an instrument in writing signed by the Company and
the registered holder hereof. All notices and other communications from the
Company to the holder of this Warrant shall be mailed by first class registered
or certified mail, postage prepaid, to the address furnished to the Company in
writing by the last holder of this Warrant who shall have furnished an address
to the Company in writing. The invalidity or unenforceability of any provision
hereof shall in no way affect the validity or enforceability of any other
provisions.

        11. TERMINATION. This Warrant (and the right to purchase securities upon
exercise hereof) shall terminate five (5) years from the date this agreement is
executed.

II    RIGHT OF FIRST REFUSAL


                                      -2-
<PAGE>   3
        If, at any time prior to the expiration of the period set forth in
Article V(I) below, the company should desire to issue in any transaction not
registered under the Securities Act, any Equity Securities, it shall give the 
Purchasers and Mazur (together, the Purchasers and Mazur shall be referred to 
in this Section II as "Shareholders") a first right of refusal to purchase 
such Shareholder's pro rata share of all of such offered Equity Securities on 
the same terms as the Company is willing to sell such Equity Securities to any 
other person. The Shareholder's pro rata share of the Equity Securities shall 
be equal to the percentage that the Equity Securities of the Company held by 
the Shareholder on an as-converted basis on the date of the Company's written 
notification referred to in subparagraph (A) below, bears to all outstanding 
Equity Securities of the Company on the date of such written notification.

        A. Notices. Prior to any sale or issuance by the Company of any Equity
Securities, the company shall notify each Shareholder, in writing, of its bona
fide intention to sell and issue such Equity Securities, setting forth any
material terms under which it proposes to make such sale. Within fifteen (15)
days after receipt of such notice, each Shareholder shall notify the Company
whether the Shareholder exercises its option and elects to purchase the
Shareholder's pro rata share (or any part hereof) of the Equity Securities so 
offered.

        B. Procedure. If any Shareholder has failed to exercise its option to
purchase all of its pro rata portion of the Equity Securities upon the terms
and conditions set forth in Subsection (A) notice, the Company may, during the
period of ninety (90) days following the expiration of such option period, sell
and issue such securities as to which such Shareholder has not exercised its
option to any other person upon the same terms and conditions as those set forth
in the notice to the Shareholders. In the event the Company has not sold the
Equity Securities within said ninety (90) day period, the Company shall not
thereafter issue or sell any Equity Securities without first offering such
securities to the Shareholders in the manner provided above.

        C. Closing. If a Shareholder gives the Company notice that it desires
to purchase any of the Equity Securities offered by the Company, payment for the
Equity Securities shall be by check, or wire transfer, against delivery of the
securities at the executive offices of the Company within ten (10) days after
giving the Company such notice, or, if later, the closing date for the sale of
such Equity Securities to third parties. The Company shall take all such action
as may be required by any regulatory authority in connection with the exercise
by the Shareholder of the right to purchase Equity Securities as set forth in
this Section II.

        D. Exceptions. The right of first refusal contained in this Section II
shall not apply to (i) the issuance by the Company of Equity Securities
exclusively to employees or directors of, or consultants to the Company
pursuant to the approval of the Board of Directors, (ii) the issuance of Common
Stock of the Company upon conversion of Preferred Stock, (iii) the issuance of
any Equity Securities in connection with any borrowings, direct or indirect,
from financial institutions by the Company, whether or not presently
authorized, (iv) the issuance of any Equity Securities in connection with
leases by the Company of equipment, (v) Equity Securities issued to vendors or
customers of the Company if such issuance is approved by the Board of
Directors; or (vi) any Equity Securities issued in connection with an
acquisition or SEC Rule 145 transaction.


                                      -3-
<PAGE>   4
        E. Assignment. A Shareholder's right to purchase any Equity Securities
pursuant to this Section II may be assigned by the Shareholder to an affiliate
of the Shareholder or the purchaser or substantially all of the assets or
securities of the Shareholder. For the purposes of this subparagraph (E), an
"affiliate" shall mean any partner or shareholder of the Shareholder, any
person or entity that director or indirectly through one or more intermediaries
controls or is controlled by or is under common control with a Shareholder.

III RIGHT OF CO-SALE

        A. Right of Co-Sale. If Mazur proposes to sell or transfer any Co-Sale
in one or more transactions which will result in the transfer of 200,000 or
more shares of Equity Securities by Mazur, then Mazur shall promptly give
written notice (the "Co-Sale Notice") to the Company and to the Purchasers at
least 20 days prior to the closing of such sale or transfer. The Co-Sale Notice
shall describe in reasonable detail the proposed sale or transfer, including
the number of Co-Sale Shares to be sold or transferred (the "Noticed Co-Sale
Shares"), the nature of such sale or transfer, the consideration to be paid,
and the name and address of each prospective purchaser or transferee. In the
event that the sale or transfer is being made pursuant to Subsection B below,
the Co-Sale Notice shall state under which portion of such Subsection the sale
or transfer is being made.

                1. Each Purchaser shall have the right, exercisable upon
written notice to Mazur within 15 days of the date of the Co-Sale Notice, to
participate in such sale on the same terms and conditions specified in the
Co-Sale Notice.

                2. Each Purchaser may sell all or any part of that number of
shares of Common Stock equal to the product obtained by multiplying (i) the
aggregate number of Noticed Co-Sale Shares covered by the Co-Sale Notice, by
(ii) a fraction the numerator of which is the number of shares of Common Stock
owned by the Purchaser at the time of the sale or transfer and the denominator
of which is the total number of shares of Common Stock owned by Mazur and the
Purchasers at the time of the sale or transfer.

                3. A purchaser electing to exercise the co-sale right provided
in this section shall effect its participation in the sale by promptly
delivering to Mazur for transfer to the prospective purchaser one or more
certificates, properly endorsed for transfer, which represent:

                        a. the type and number of shares of Common Stock which
the Purchaser elects to sell; or

                        b. that number of shares of Preferred Stock which is at
such time convertible into the number of shares of Common Stock which the
Purchaser elects to sell; provided, however, that if the prospective purchaser
objects to the delivery of Preferred Stock in lieu of Common Stock, the
Purchaser shall convert such Preferred Stock into Common Stock and deliver
Common Stock as provided in subsection 3(a) above. The Company agrees to make
any such conversion concurrent with the actual transfer of such shares to the
purchaser.


                                      -4-

                4.      If the Purchasers do not participate in the sale of the
Noticed Co-Sale Shares, Mazur may, not later than ninety (90) days following
delivery to the Company and the Purchasers of the Co-Sale Notice, enter into an
agreement providing for the closing of the transfer of the Noticed Co-Sale
Shares within sixty (60) days of such agreement on terms and conditions not
more favorable to the transferor than those described in the Co-Sale Notice.

        B.      Exempt Transfers. Notwithstanding the foregoing, the provisions
of this Article III shall not apply to (i) any transfer to the ancestors,
descendants or spouse or to trusts for the benefit of such persons or Mazur; or
(ii) any bona fide gift; provided that the pledgee, transferee or donee shall
furnish the Purchasers with a written agreement to be bound by and comply with
all provisions of this Article III. Such transferred shares remain "Co-Sale
Shares" hereunder, and such pledgee, transferee or donee shall be treated
equivalently to Mazur for purposes of this Agreement. In addition, the
provisions of this Article III shall not apply to the sale of any Co-Sale
Shares (i) to the public pursuant to a registration statement filed with, and
declared effective by, the SEC; (ii) if prior to such sale Mazur (together with
all of his transferees) held less than 5% of the Company's outstanding shares;
or (iii) if prior to such sale Mazur (A) is no longer an officer or director of
the Company or its affiliates, and (B) holds less than 50% of the outstanding
securities of the Company, on a fully-diluted, as-converted-to Common Stock
basis. 

        C.      Prohibited Transfers. In the event Mazur should sell any
Co-Sale Shares in contravention of the co-sale rights of the Purchasers under
this Agreement (a "Prohibited Transfer"), the Purchasers, in addition to such
other remedies as may be available at law, in equity or hereunder, shall have
the put option provided below, and Mazur shall be bound by the applicable
provisions of such option.

                1.      In the event of a Prohibited Transfer, each Purchaser
shall have the right to sell to Mazur the type and number of shares of Common
Stock equal to the number of shares such Purchaser would have been entitled to
transfer to the purchaser had the Prohibited Transfer been effected pursuant to
and in compliance with the terms hereof. The price per share at which the
shares are to be sold to Mazur shall be equal to the price per share paid by
the purchaser to Mazur in the Prohibited Transfer. Within 90 days after the
later of the dates on which the Purchaser (A) received notice of the Prohibited
Transfer or (B) otherwise became aware of the Prohibited Transfer, the
Purchaser shall, if exercising the option created hereby, deliver to Mazur the
certificate or certificates representing shares to be sold, each certificate to
be properly endorsed for transfer. Mazur shall, upon receipt of the certificate
or certificates for the shares to be sold by the Purchaser pursuant to this
subsection C, pay the aggregate purchase price therefor in cash or by other
means acceptable to the Purchaser.

                2.      Notwithstanding the foregoing, any attempt by Mazur to
transfer Co-Sale Shares in violation of this Agreement shall be void and the
Company agrees it will not effect such a transfer nor will it treat any alleged
transferee as the holder of such shares without the written consent of the
Purchaser. 

                                      -5-
<PAGE>   6

        D.      Legend.  Each certificate representing shares of stock now
owned by Mazur or issued to any person in connection with a transaction
pursuant to Article III(B) hereof shall be endorsed with the following legend:

                THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
                REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
                CONDITIONS OF A CERTAIN INVESTOR RIGHTS AGREEMENT BY AND BETWEEN
                THE PURCHASER, THE COMPANY AND CERTAIN HOLDERS OF STOCK OF THE
                COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN
                REQUEST TO THE SECRETARY OF THE COMPANY.


IV      S-3 REGISTRATION RIGHT

        A.      Form S-3.  After the Company has qualified for the use of Form
S-3, or its successor form, the Holders of at least twenty percent (20%) of the
outstanding Registrable Securities ("Initiating Holders") shall have the right
to request one registration on Form S-3 (such request shall be in writing and
shall state the number of shares of Registrable Securities to be disposed of
(the "Offered Registrable Securities") and the intended method of disposition
of shares by such Holder), subject only to the following:

                1.      The Company shall not be required to effect more than
one such registration, except that the Company shall effect one additional Form
S-3 registration at the request of the Holder, pursuant to all the terms and
conditions of this Section IV, in the event that during the effective period of
the first registration statement filed pursuant to this Section IV, the Holder
has not sold at least 90% of the Offered Registrable Securities. Such
additional S-3 registration shall cover only the Offered Registrable Securities
not sold pursuant to the first registration under this Section.

                2.      The Company shall not be required to effect a
registration unless the Initiating Holder seeks to register at least 50% of the
Registrable Securities held by such Initiating Holder as of the date of this 
Agreement.

        The Company shall promptly give written notice to all Holders of
Registrable Securities of the receipt of a request for registration pursuant to
this section and shall provide a reasonable opportunity for other Holders to
participate in the registration. The Company will use its best efforts to
effect promptly the registration of all shares of Registrable Securities on
Form S-3 to the extent requested by the Holder thereof for purposes of
disposition; provided, however, that if the Company shall furnish to such
Holders a certificate signed by the President or Chief Executive Officer of the
Company stating that in the good faith judgement of the Board of Directors it
would be seriously detrimental to the Company for such registration statement
to be filed at the date filing would be required and it is therefore essential
to defer the filing of such registration statement, the Company shall be
entitled to delay the filing of such registration statement not more than once
for an additional period of up to sixty (60) days.


                                      -6-

<PAGE>   7
        B.  Expenses of Registration.  All expenses incurred in connection
with any registration, qualification or compliance pursuant to this Agreement,
including without limitation, all registration, filing and qualification fees,
printing expenses, fees and disbursements of counsel for the Company and
expenses of any special audits incidental to or required by such registration,
shall be borne by the Company except as follows:

            1.  The Company shall not be required to pay for expenses of 
any registration proceeding begun pursuant to this Section, the request for
which has been subsequently withdrawn by the Initiating Holders, in which case,
such expenses shall be borne by the Holders requesting withdrawal.
Notwithstanding the foregoing, if at the time of such withdrawal (i) the Holder
has learned of a material adverse change in the condition, business or prospects
of the Company from that known to the Holder at the time of its request, and
(ii) the Company knew or had reason to know of the likelihood of such material
adverse change at the time of its request and did not inform the Holder thereof,
then the Company shall be required to pay such expenses.

            2.  The Company shall pay the reasonable fees of a single counsel
acting on behalf of all selling Holders.

            3.  The Company shall not be required to pay underwriters' fees,
discounts or commissions relating to the Registrable Securities.

        C.  Registration Procedures.  In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company will keep each Holder participating therein advised in writing as
to the initiation of each registration, qualification and compliance and as to
the completion thereof. At its expense the Company will:

            1.  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the
Holders offering Registrable Securities registered thereunder, keep such
registration statement effective for up to one hundred eighty (180) days.

            2.  Prepare and file with the SEC such amendments and supplements
to such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by
such registration statement.

            3.  Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as it may reasonably request in order
to facilitate the disposition of Registrable Securities owned by it.

            4.  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as

<PAGE>   8
shall be reasonably requested by the Holders, provided that the Company shall
not be required in connection therewith or as a condition thereto to qualify to
do business or to file a general consent to service of process in any such
states or jurisdictions.

                5.      In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each
participating Holder shall also enter into and use best efforts to perform its
obligations under such an agreement.

                6.      Notify the Holders offering securities pursuant to such
Registration Statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing. 

                7.      Furnish, at the request of any Holder, on the date that
the securities are delivered to the underwriters for sale in connection with a
registration being sold through underwriters, (i) an opinion, if any, dated
such date, of the counsel representing the Company for the purposes of such
registration, in form and substance as is customarily given to underwriters in
an underwritten public offering, addressed to the underwriters and to the
Holder and (ii) a letter dated such date, from the independent certified public
accountants of the Company, in form and substance as is customarily given by
independent certified public accountants to underwriters in an underwritten
public offering, addressed to the underwriters, if any, and to the Holder.

        D.      Indemnification.

                1.      The Company will indemnify and hold harmless each
Holder, each of its officers, directors and partners, and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which such registration, qualification or compliance has been
effected pursuant to this Agreement, and each underwriter, if any, and each
person who controls any underwriter of the Registrable Securities held by or
issuable to such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereto) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any registration statement, preliminary or final prospectus, or any amendment
or supplement thereto, offering circular or other document (including any
related registration statement, notification or the like) incident to any such
registration, qualification or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation or
alleged violation by the Company relating to action or inaction required of the
Company in connection with any rule or regulation promulgated under the
Securities Act or any state securities law applicable to the Company and will
reimburse each such Holder within the meaning of Section 15 of the Securities
Act, each of its officers, directors and partners, and each person controlling
each such Holder, each such underwriter and each person who controls any such
underwriter, for

                                      -8-
<PAGE>   9
any reasonable legal and any other expenses, as incurred, in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action; provided, however, that the Company will not be liable in any such case
to the extent that any such claim, loss, damage or liability arises out of or
is based on any untrue statement or omission based upon written information
furnished to the Company in an instrument duly executed by such Holder or
underwriter specifically for use therein, and provided further that the
agreement of the Company to indemnify any underwriter and any person who
controls such underwriter contained herein with respect to any such preliminary
prospectus shall not inure to the benefit of any underwriter, from whom the
person asserting any such claim, loss, damage, liability or action purchased the
stock which is the subject thereof, if at or prior to the written confirmation
of the sale of such stock, a copy of the prospectus (or the prospectus as
amended or supplemented) was not sent or delivered to such person, excluding
the documents incorporated therein by reference, and the untrue statement or
omission of a material fact contained in such preliminary prospectus was
corrected in the prospectus (or the prospectus as amended or supplemented).

                2.      Each Holder will, if Registrable Securities held by or
issuable to such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify and hold
harmless the Company, each of its directors and officers, each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company within the meaning of the Securities Act
against all claims, losses, expenses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any preliminary or final
prospectus, offering circular or other document (including any related
registration statement, notification or the like) incident to any such
registration, qualification or compliance or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company, such directors, officers, partners, persons or underwriters for any
reasonable legal or any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is
made in such registration statement, prospectus, offering circular or other
document solely in reliance upon and in conformity with written information
furnished to the Company in an instrument duly executed by such Holder
specifically for use therein, and provided further that the agreement of such
Holder to indemnify any underwriter and any person who controls such
underwriter contained herein with respect to any such preliminary prospectus
shall not inure to the benefit of any underwriter, from whom the person
asserting any such claim, loss, damage, liability or action purchased the stock
which is the subject thereof, if at or prior to the written confirmation of the
sale of such stock, a copy of the prospectus (or the prospectus as amended or
supplemented) was not sent or delivered to such person, excluding the documents
incorporated therein by reference, and the untrue statement or omission of a
material fact contained in such preliminary prospectus was corrected in the
prospectus (or the prospectus as amended or supplemented). Notwithstanding the
foregoing, in no event shall the indemnification provided by any Holder
hereunder exceed the net proceeds received by such Holder for the sale of such
Holder's securities pursuant to such registration.

                                      -9-
<PAGE>   10
                3.      Each party entitled to indemnification under this
Section ("Indemnified Party") shall give notice to the party required to
provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may
be sought. The Indemnified Party shall promptly permit the Indemnifying Party
to assume the defense of any such claim or any litigation resulting therefrom,
provided that counsel for the Indemnifying Party, who shall conduct the defense
of such claim or litigation, shall be approved by the Indemnified Party (whose
approval shall not be unreasonably be withheld). The Indemnified Party may
participate in such defense and hire counsel at such party's own expense. The
failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations hereunder, unless such
failure is materially prejudicial to an Indemnifying Party's ability to defend
such action. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of the Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. Any Indemnified Party shall cooperate with the Indemnifying Party
in the defense of any claim or litigation brought against such Indemnified
Party. 

        E.      Lock-Up Provision. Upon receipt of a written request by the
Company or by its underwriters, the Holders shall not sell, sell short, grant
an option to buy, or otherwise dispose of shares of the Company's Common Stock
or other securities (except for any such shares included in the registration)
for a period of one hundred and eighty (180) days following the effective date
of the initial registration of the Company's securities; provided, however,
that the Holders shall have no obligation to enter into the agreement described
in this Section IV(E) unless all executive officers, directors and holders of
three percent (3%) or more of the outstanding voting securities of the Company
and all other Holders and holders of other registration rights from the Company
enter into similar agreements. The Company may impose stop-transfer
instructions with respect to the shares (or securities) subject to the
foregoing restriction until the end of said 180-day period.

        F.      Information by Holder. The Holders included in any registration
shall promptly furnish to the Company such information regarding such Holder or
Holders and the distribution proposed by the Holders as the Company may request
in writing and as shall be required in connection with any registration,
qualification or compliance referred to herein.

        G.      Rule 144 Reporting. With a view to making available to Holders
of Registrable Securities the benefits of certain rules and regulations of the
SEC which may permit the sale of the Registrable Securities to the public
without registration, at all times after 90 days after the effective date of
the first registration filed by the Company for an offering of its securities
to the general public the Company agrees to:

                1.      Make and keep public information available, as those
terms are understood and defined in SEC Rule 144.

                                      -10-
<PAGE>   11
                2.      File with the SEC in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Securities Exchange Act of 1934, as amended (the "Exchange Act").

                3.      So long as a Holder owns any Registrable Securities, to
furnish to the Holder forthwith upon the Holder's request a written statement
by the Company as to its compliance with the reporting requirements of said
Rule 144 (at any time after 90 days after the effective date of the first
registration statement filed by the Company for an offering of its securities
to the public) and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed by the Company as the Holder may reasonably request in
availing itself of any rule or regulation of the SEC allowing the Holder to
sell any such securities without registration.

        H.      Transfer of Registration Rights. A Holder's rights under this
Section IV may not be assigned by the Holder except that the Holder may assign
such rights to a transferee of all of the Registrable Securities. No such
transfer or assignment shall be effective until such transferee or assignee
agrees in writing to become subject to the obligations of the transferring
Holder hereunder.

V       WAIVER OF PRIOR RIGHT OF FIRST REFUSAL

        By their signatures below, Mazur and Medicine Partners waive their
right of first refusal and all other rights pursuant to article II of the
Original Investor Rights Agreement with respect to the issuance, as of the date
of this Agreement, to G.C. Investments of 226,670 shares of the Company's
Series E Preferred Stock and a Warrant to purchase 106,667 shares of the
Company's Series E Preferred Stock and the shares of Series E Preferred Stock
issuable upon conversion of such Warrant.

VI      MISCELLANEOUS

        A.      Notices. All notices or other communications required or
permitted to be delivered hereunder shall be in writing signed by the party
giving the notice to the Company at 16825 Via Del Campo Court, San Diego, CA
92127, Attn: President, and to the Purchaser at the addresses set forth on the
signature page of this Agreement. Any Purchaser may at any time change the
address to which notice shall be mailed by giving notice of such change to the
Company and to the other parties and such notice shall be deemed given when
received by the other party hereto.

        B.      Amendment. This Agreement may be amended with the written
consent of the Company and the Purchasers, except that no amendment affecting
Mazur shall be made to this Agreement without the prior written consent of
Mazur. 

        C.      Entire Agreement. This Agreement constitutes the entire
agreement of the parties with respect to the matters contemplated herein. This
Agreement supersedes any and all prior understandings as to the subject matter
of this Agreement. Without limiting the 

                                      -11-
<PAGE>   12
generality of the foregoing, this Agreement replaces and supersedes the
Original Investor Rights Agreement.

        D.      Binding Effect; Assignment. This Agreement shall be binding
upon and inure to the benefit of the successors and assigns of the respective
parties hereto, except that the Company shall not have the right to assign its
rights hereunder or any interest herein, and, except as set forth in Section
IV, the rights and interests of the Purchasers shall be assignable, without the
consent of the Company, to any assignee.

        E.      General. The headings contained in this Agreement are for
reference purposes only and shall not in any way affect the meaning or
interpretation of this Agreement. In this Agreement the singular includes the
plural, the plural the singular, the masculine gender includes the neuter,
masculine and feminine genders. This Agreement shall be governed by and
construed under the laws of the State of California.

        F.      Severability. If any provision of this Agreement shall be found
by any court of competent jurisdiction to be invalid or unenforceable, the
parties hereby waive such provision to the extent that it is found to be
invalid or unenforceable. Such provision shall, to the maximum extent allowable
by law, be modified by such court so that it becomes enforceable, and, as
modified, shall be enforced as any other provision hereof, all the other
provisions hereof continuing in full force and effect.

        G.      Counterparts. This Agreement may be executed in counterparts,
all of which together shall constitute one and the same instrument.

        H.      Dispute Resolution. The parties acknowledge and agree that time
is of the essence in resolving any dispute that may arise in connection with
this Agreement. Except as provided herein, any controversy or claim arising out
of or relating to this Agreement, or the breach thereof, that cannot be
resolved between the parties in a timely manner shall be settled by binding
arbitration in accordance with the Commercial Arbitration Rules of the American
Arbitration Association ("AAA"). The expenses of the arbitration, including the
arbitrator's fees, expert witness fees, and attorneys' fees, may be awarded to
the prevailing party, in the discretion of the arbitrator, or may be
apportioned between the parties in any manner deemed appropriate by the
arbitrator. Unless and until the arbitrator decides that one party is to pay
for all (or a share) of such expenses, the parties shall each bear their own
legal and accounting fees and costs arising in connection with enforcement of
this Agreement or the Collateral Agreements. The parties shall keep
confidential the decision of the arbitrator. Notwithstanding the foregoing, the
parties may disclose information about such decision to persons who have a need
to know, such as limited partners, directors, trustees, management employees,
witnesses, experts, investors, attorneys, lenders, insurers, and others who may
be affected. Once the arbitration award has become final, if the arbitration
award is not promptly satisfied, then these confidentiality provisions shall no
longer be applicable. Notwithstanding the foregoing, the parties will be
entitled to enforce their rights under this Agreement specifically (without
posting a bond or other security). The parties hereto agree and acknowledge
that money damages may not be an adequate remedy for any breach of the
provisions of this Agreement and any party may in its sole discretion apply to
any court of

                                      -12-
<PAGE>   13
law or equity of competent jurisdiction for specific performance and/or
injunctive relief in order to enforce or prevent any violation of the
provisions of this Agreement.

        1.      Term of Agreement.  Except with respect to Sections IV and V
hereof, this Agreement shall terminate on the earlier of (a) the consummation
by the Company of any underwritten public offering of the Company's securities
in which the gross proceeds to the Company equal or exceed $15,000,000, (b) the
sale of the Company (through a merger, consolidation, sale of all or
substantially all of its assets or stock) or (c) the effective time of the
liquidation of the Company. Section V shall terminate upon the termination of 
Section IV. Section IV shall terminate at such time as the Purchaser becomes 
eligible (or would become eligible if the Purchaser continued to hold 
Registrable Securities) to sell all its Registrable Securities pursuant to 
Rule 144(k).

                         AMENDMENT TO LICENSE AGREEMENT

December 1, 1994 ("Effective Date") by and between Habley Medical Technology
Corporation, a California corporation ("Habley") and U.S. Medical Instruments,
Inc., a California corporation ("U.S. Medical").

                                    RECITALS

A.       Habley and U.S. Medical are parties to that certain written License
         Agreement dated as of July 1, 1992 ("License Agreement"). Pursuant to

         Patents on the terms and conditions thereof.

B.       Habley and U.S. Medical wish to amend the License Agreement on the
         terms and conditions of this Amendment. In particular, the parties wish
         to provide U.S. Medical with the opportunity to obtain a paid up
         license under the Patents pursuant to the License Agreement on the
         occurrence of certain terms and conditions as set forth in this
         Amendment.

C.       As used in this Amendment, all defined terms are as set forth in the

2.0      Grants.

         2.1 License Grant. Habley hereby grants to U.S. Medical an exclusive
license under the Patents and under the Technical Data and Trade Styles to make,
use and sell the Product for those uses identified in Paragraph 2.5 hereof in
the Territory. U.S. Medical shall have no right to grant sublicenses or licenses
or to sell, transfer, assign, mortgage, pledge or hypothecate, directly or
indirectly, or by operation of law any rights whatsoever with respect to the
License granted hereby or with respect to the Trade Styles or Advertising
Materials, and any such purported transfer shall be void except on the
conditions set forth in Sections 2.2, 2.3 and 2.4 below.

         2.2 Permitted Sublicenses. U.S. Medical may sublicense its rights under
this Agreement only with the prior written consent of Habley, which shall not be
unreasonably withheld. Unless otherwise consented to by Habley, without
limitation, any permitted sublicense agreement shall be subject to the
following:

         2.2.1 The identity of the sublicensee must be approved by Habley.

         2.2.2 The sublicensee shall agree to be bound by all applicable
provisions of this Agreement.

         2.2.3 U.S. Medical shall affirm its obligations to pay royalties to
Habley for all products sold.

respect to each sublicense.

         2.3 Quality Assurance Validation. U.S. Medical shall maintain, at all
times, such quality assurance, control and validation standards of compliance
which shall be acceptable to Habley, Habley's approval for which shall not be

withheld.

         2.5 Limited Field Of License Grant. The License granted pursuant to
Paragraph 2.1 is granted specifically and solely for applications within the
specific field of administration of pharmaceuticals or other fluids by syringe
and for no other use or specification. Any manufacture, use or sale of
Product(s) outside of the authorized field shall terminate this Agreement.

         2.6 Rights Reserved. Except as specifically provided to the contrary in
this Agreement, nothing contained in this Agreement shall be deemed to grant any
license or other rights to either party under any patents, trademarks, trade
names, copyrights, design rights or trade secrets of the other party. No rights
of any nature or

                                      -3-
<PAGE>   14
kind, other than those specifically enumerated in this Agreement under Sections
2.1 through 2.5, are granted or covenanted by either party to the other pursuant
to this Agreement. Except as set forth in this Agreement, either party may
freely develop, license, transfer or sell products not subject to this
Agreement, to third parties at its sole and absolute discretion, without notice
to the other.

                  2.7 Product Development. After the execution of this Agreement
and during the term of this Agreement, as U.S. Medical reasonably requests,
Habley shall transmit to U.S. Medical brief verbal reports of Technical Data
concerning the Patents and Products as deemed by Habley to be reasonable,
necessary and appropriate. In addition, if requested by U.S. Medical and if
deemed solely by Habley to be within the scheduling priorities and prototype
manufacturing capabilities of Habley and unless otherwise agreed upon, Habley
shall supply to U.S. Medical, at Habley's fully- burdened cost of operation plus
fifteen percent (15%), reasonable quantities of prototypes of the Products for
confidential laboratory and/or confidential marketing analysis testing and/or
clinical testing purposes only, in raw or finished package form, as reasonably
requested by U.S. Medical and as agreed to and accepted by Habley.

3.0      Non-Refundable License Fee. In partial consideration for the license
granted with respect to the Products, U.S. Medical shall pay to Habley a non-
refundable fee, which shall not be applied as an advance against Royalties,
payable as follows:

         3.1 One Hundred Twenty-Five Thousand U.S. Dollars ($125,000.00)
concurrently with the execution of this Agreement.

         3.2 Sixty-Two Thousand Five Hundred U.S. Dollars ($62,500.00) within
three calendar months of execution of this Agreement.

         3.3 Sixty-Two Thousand Five Hundred U.S. Dollars ($62,500.00) within
six calendar months of execution of this Agreement.

         If U.S. Medical shall fail to timely make any payment due pursuant to
this Paragraph 3, this Agreement and all licenses and rights granted to U.S.
Medical hereunder shall be terminated in accordance with Paragraph 17.2.1. No
fees pursuant to this Paragraph 3.0 are refundable.

4.0      Royalty.

         4.1 Amount. U.S. Medical shall pay to Habley a royalty in an amount
equal to five percent (5%) of the Net Selling Price with respect to all sales of
the Product(s) in countries with patent protection and two and one-half percent
(2-1/2%) of the Net Selling Price with respect to all sales of the Product in
countries without patent protection where the Product(s) incorporate the
Technical Data and/or Trade Styles. If

                                     - 4 -
<PAGE>   15
any Product is sold in a package, bundle, set or otherwise together with, or as
a part of, any product or device not subject to royalty pursuant to this
Agreement, the royalty due from U.S. Medical to Habley shall be based upon the
usual Net Selling Price received upon comparable sales for the Product subject
to this Agreement when sold alone and not the total price of the package, set or
bundled product.

         4.2 Minimum Sales/Royalty.

                  4.2.1 The minimum royalty to be paid by U.S. Medical to Habley
with respect to sales of all Products in the Territory, exclusive of any
Additional Territories, shall be One Hundred Thousand U.S. Dollars ($100,000.00)
for the second full calendar year following the First Commercial Launch of the
first of the Products, or beginning 12 months after the Effective Date,
whichever event occurs first ("First Period"), One Hundred Fifty Thousand U.S.
Dollars ($150,000.00) for the third full calendar year following the First
Period of the first of the Licensed Products, or 24 months after the Effective
Date, whichever event occurs first ("Second Period"), and Two Hundred Thousand
U.S. Dollars ($200,000.00) for each full calendar year thereafter during the
term of this Agreement ("Third Period").

                  4.2.2 If the sales of the Products are not sufficient during
the First Period and Second Period only, to satisfy the minimum royalty
obligation set forth above, then U.S. Medical shall have the right of paying
such minimum royalty amount to Habley. Beginning with the calendar year
commencing on the expiration of the Second Period, minimum royalty amounts must
be met only through income generated solely by bonafide actual sales of Products
licensed herein by U.S. Medical.

                  4.2.3 If the Signator of this Agreement and/or chairman or
president of U.S. Medical, if U.S. Medical is a corporation, resigns or is
terminated subsequent to the execution of this Agreement but prior to the First
Commercial Launch of any Product(s), without the prior written consent of Habley
which shall not be unreasonably withheld, or dies, or is otherwise
incapacitated, the Minimum Royalties due hereunder shall immediately become due
and payable to Habley as set forth hereinabove in Paragraph 4.2.

                  4.2.4 If U.S. Medical shall fail to meet its obligations under
Paragraph 4.2.1, 4.2.2, or 4.2.3 with respect to payments of minimum royalties
or sales, all licenses and rights granted to U.S. Medical hereunder shall be
terminated in accordance with Section 17.2.1.

                  4.3 Competition. If in any country or territory, including the
United States, any product which is the same as any of the Products shall be
sold by a third party licensed by reason of a law providing for compulsory
licensing (and provided such compulsory licensing is not attributable to U.S.
Medical's failure to use its best efforts to market, distribute and/or
sublicense such of the Products in such country), then upon so notifying Habley,
U.S. Medical shall have the right, as its sole and

                                     - 5 -
<PAGE>   16
exclusive remedy, to reduce the royalty payable by U.S. Medical to Habley on
the Net Selling Price of such of the Licensed Products in such country or
territory pursuant to Section 4.1 to seventy-five percent (75%) of the rate
specified in Section 4.1.

                  4.4 Expiration of Patents. Upon the expiration of each Patent
for a Product licensed under this Agreement, or if all or substantially all of
the patent claims obtained by Habley in the United States covering the
manufacture or use of a Product are held invalid in a final judgment by a court
of competent jurisdiction, U.S. Medical shall continue to have a Non-Exclusive
License to make, use and sell the Product, if U.S. Medical is utilizing among
other things, the Trade Styles and Technical Data in accordance with the
provisions of this Agreement for the balance of the Term, and shall pay to
Habley an amount equal to 50% of the royalty otherwise payable pursuant to this
Paragraph 4 for the balance of the Term. For the purposes of this paragraph, the
term "Non-Exclusive License" means that Habley will not make, use or sell the
Products through importers, distributors, licensees or otherwise.

                  4.5 Material Change. Because the Patents give Habley a limited
period of time in which to exclusively commercialize any products based thereon,
Habley has taken particular care and attention to select the licensee as the
entity to commercialize the Products, and particular attention to
representations by U.S. Medical to Habley concerning U.S. Medical's management,
control, ownership, resources, and business plan. In the event of any material
change prior to First Commercial Launch, and prior to payment in full of
Non-Refundable License Fee, as per Paragraph 3.0 hereinabove, whether voluntary
or involuntary, in the management, control, ownership or resources of U.S.
Medical, which adversely affects U.S. Medical's abilities to carry out its
obligations under this Agreement, as determined in the sole reasonable
discretion of Habley, Habley shall have the right to convert the License granted
to U.S. Medical hereunder to a Semi-Exclusive License for the balance of the
Term, in which case U.S. Medical shall pay to Habley an amount equal to 75% of
the royalty otherwise payable pursuant to this Paragraph 4 for the balance of
the Term.

                  4.6 Royalty-Free Promotional Samples. Such samples for the
purpose of introducing the U.S. Medical syringe to end users may be supplied to
such end users on a royalty free basis, providing said syringes are given by
U.S. Medical free of any charge and that the total number of said promotional
U.S. Medical syringes shall not exceed 10% of the total yearly production of
U.S. Medical syringes which otherwise would be subject to this Agreement. This
Paragraph 4.6 will be valid only for the first 12 months following execution of
this Agreement and shall be discontinued at that time with no additional notice
required.

5.0      Payments, Reports and Records.

                  5.1 Timing of Payment(s). Royalties shall be paid by U.S.
Medical to Habley quarterly in an amount equal to not less than (i) twenty-five
percent (25%) of the annual minimum royalty amounts set forth in Section 4.2.1
within ten (10) calendar

                                     - 6 -
<PAGE>   17
days following the end of the calendar quarter to which the same is attributable
until royalties paid exceed the annual minimum; and, (ii) the balance of the
accrued royalty for such quarter within thirty (30) days following the end of
such quarter. Royalties with respect to sales of Product(s) prior to
commencement of Minimum Royalty payments shall be paid quarterly.

                5.2 Statement. U.S. Medical will render to Habley with each such
royalty payment a certified written statement setting forth all computational
details of the royalties payable for such quarter and a certified statement from
a corporate officer of U.S. Medical setting forth the amount of sales and that
the amount of the royalty paid has been calculated in accordance with this
Agreement. U.S. Medical will keep records in sufficient manner and detail to
verify sales and to enable the royalties to be calculated.

                5.3 Verification. Habley (and its employees, agents, contractors
and accountants) shall, at reasonable times and with reasonable notice and at
Habley's expense, have access to, and may make copies of, U.S. Medical's records
concerning promotional distribution (as per Paragraph 4.6 hereinabove), sales
and manufacturing of the Product(s) during normal business hours for the purpose
of verifying for Habley, with respect to any calendar quarter ending not more
than three (3) calendar years prior to the date of such request, the correctness
of any report and/or payment due under this Agreement.

                5.4 Method of Payment.

                    5.4.1 Exchange Rate. All royalties shall be paid to Habley
in U.S. Dollars. As to any sales made by U.S. Medical in another currency, the
amount of payment shall be determined by converting from the currency in which
the sales are made at the rate of exchange quoted by the Wall Street Journal for
the last business day of the calendar quarter to which the royalty payment
pertains.

                    5.4.2 Taxes. Except as provided in this Paragraph 5.4.2,
U.S. Medical shall be responsible for any taxes assessed on account of income,
sales, use or inventory. Habley shall be responsible for any taxes on account of
income by virtue of the license fees and royalty payments received from U.S.
Medical. If any taxes are assessed against Habley on account of income earned in
or royalty remittable from any country and for which provision is now or
hereinafter made in the law for withholding from royalties to be remitted to
Habley there shall, unless exemption has been obtained, be deducted from such
royalty and shall be paid by U.S. Medical to the proper tax authorities the
amount of such withholding required by the law, and U.S. Medical shall forthwith
pay to Habley, in addition to any other amounts due from U.S. Medical to Habley,
an amount equal to the payment withheld. Habley shall join with U.S. Medical, if
U.S. Medical shall so reasonably request, at no expense to Habley, in applying
for exemption from taxation upon royalties payable by U.S. Medical under this
Agreement pursuant to any international convention or agreement.

against U.S. Medical, U.S. Medical shall, at U.S. Medical's sole cost and
expense, take all necessary actions to prevent any further breach of the
confidentiality provisions and to obtain all copies of documents which embody or
refer to the Technical Data or Information.

             6.1.4 If any subpoena or request is received seeking production or
disclosure of any Technical Data or Information, the party receiving such
subpoena, process or request shall (a) immediately notify the other party in
writing; and, (b) decline to produce or discharge the Technical Data or

             6.1.5 Except as otherwise be provided herein, all Technical Data
and Information including, without limitation, monographs, specifications, flow
sheets, descriptions, data, samples and other tangible material pertaining
thereto shall be the property of Habley. Upon termination of this Agreement,
U.S. Medical shall deliver to Habley all Technical Data and Information, in
whatever form, and all copies thereof, with the exception that U.S. Medical may
retain one, strictly confidential, single copy in its U.S.A. headquarters in
specially secured legal files solely for the purpose of identifying its
obligations under this Agreement, which copy shall continue to be deemed
"TECHNICAL DATA" and "INFORMATION" and shall continue to be subject to the
confidentiality provisions of this Section 6.

             6.1.6 The foregoing obligations of confidentiality shall not apply
to:

               a) Information known to the receiving party prior to the date of
its disclosure pursuant to this Agreement (as evidenced by written documentation
of such prior knowledge submitted to the disclosing party in confidence by the
receiving party within a reasonable time thereafter but not to exceed ten (10)
calendar days) and not obtained or derived directly or indirectly from the
disclosing party;

               b) Information which lawfully is or becomes public, or available
to the general public otherwise than through an act or default of any party to

the other party and transmitted to the other party within five (5) days
thereafter. The written confirmation shall bear clearly the notation
"CONFIDENTIAL", shall identify the particular Technical Data or Information that
is considered confidential, and shall be addressed to the officers and/or
employees of a receiving party known or believed by the submitting party to be
the persons who received the non-written disclosure of confidential Technical
Data or Information.

         6.3 NOT IN THE PUBLIC DOMAIN. For the purposes of this Agreement,
specifics disclosed as part of Technical Data or Information shall not be deemed
to be in the public domain, or in the prior possession of a party merely because
it is embraced by more general information in the public domain, or by more
general information in the prior possession of a party.

         6.4 ENTIRE CONFIDENTIALITY AGREEMENT. This Agreement supersedes any
prior Confidentiality Agreements between the parties with respect to this
subject matter.

8.0      PROSECUTION OF PATENT APPLICATIONS AND 510-K APPLICATIONS.

         8.1 PROSECUTION OF PATENT APPLICATIONS BY HABLEY. The definition of
Patents in Paragraph 1.7 and in Exhibit "A" attached hereto, contains a
description of those of Habley's United States and foreign patents and patent
applications covered by this Agreement. Habley agrees to diligently prosecute
said United States applications and any and all United States patent
applications which may hereafter be filed (subsequent to the execution of this
Agreement) relating to the Products ("Additional Patent Application"), and to
keep U.S. Medical reasonably advised as to all material developments in
connection with the prosecution of said applications in a timely manner after
such developments are known to, and evaluated by, Habley. With respect to the
Patent licensed hereunder, U.S. Medical shall see and assure that any applicable
requirements for the affixing of notices on the Products are met. U.S. Medical
shall pay to Habley within thirty (30) days of billing an amount equal to fifty
percent (50%) of the actual expenses, for drafting, filing, and maintenance of
such Additional United States Patent Applications. U.S. Medical shall pay to
Habley within thirty (30) days of billing an amount equal to one hundred percent
(100%) of the actual expenses for drafting, filing, prosecution, maintenance and
enforcement of any corresponding foreign patent applications whose filing is
approved in advance by U.S. Medical. U.S. Medical acknowledges that Habley may,
in its sole and absolute discretion, file foreign patent applications on a
country-by-country basis directly in each country. U.S. Medical further
acknowledges that Habley may, at its sole and absolute discretion, file a
separate patent application for each claim made in the patents in Japan so as to
maximize patent protection under Japan's narrow claim interpretation practices.
U.S. Medical shall not be responsible for the costs of any individual patent
application in excess of Three Hundred Thousand Dollars ($300,000.00) unless
approved by U.S. Medical in writing prior to its filing. U.S. Medical's
obligations under this Paragraph 8.1 shall be limited to One Hundred and Fifty
Thousand Dollars

                                     - 11 -
<PAGE>   22
($150,000.00) per annum, adjusted upwardly each year pursuant to the "Cost of
Living Index," as established for the Orange County, California location, or as
the parties mutually agree. Prototypes which Habley in its sole opinion deems
necessary for the "reduction to practice" of such patent application shall be
deemed an actual expense subject to reimbursement as set forth in this Paragraph
2.6 on a fully-burdened time and materials basis plus fifteen percent (15%).

         8.2 PROSECUTION OF PATENT APPLICATIONS BY U.S. MEDICAL IN HABLEY'S
NAME. U.S. Medical shall, upon notice from Habley of the particular foreign
jurisdiction involved, prosecute all foreign patent applications described in
the definition of Patents in Paragraph 1.7, in Habley's name, but at U.S.
Medical's expense. In addition, U.S. Medical shall, upon notice from Habley of
the particular foreign jurisdiction involved, prosecute all additional foreign
patent applications required by Habley, in Habley's name, at U.S. Medical's
expense, for any Additional Territories. U.S. Medical shall employ only such
agents or attorneys as may be approved in advance and in writing by Habley and
shall not transmit any proprietary information to any agent or attorney until
receipt of such written approval. In the event that U.S. Medical shall not
prosecute any patent in a foreign jurisdiction, Habley may notify U.S. Medical
of its intent to prosecute such patent in such jurisdiction at U.S. Medical's
expense, which costs and expenses U.S. Medical shall reimburse to Habley within
fifteen (15) days of receipt of an invoice.


9.       PATENT INFRINGEMENT. If any of the claims in the Patents are infringed
by a third party by the sale of a product Habley shall have the exclusive right
to institute suit under the Patents to enjoin the infringement and for damages
for a period of one hundred and twenty (120) days after Habley receives notice
of the infringement from U.S. Medical. If Habley brings suit: U.S. Medical shall
cooperate with Habley to a reasonable extent requested by Habley, Habley shall
have the right to bring suit in the name of U.S. Medical as well as Habley, U.S.
Medical shall have the right to be represented by legal counsel of its choice at
its expense during the conduct of such infringement suit, costs, expenses and/or
damages recovered from the infringer shall first be applied to reimburse Habley
for Habley's reasonable costs and expenses actually incurred and the remainder
of such recovery shall be paid to Habley on account of loss of royalty, and any
additional recovery shall be shared by the parties fifty percent (50%) for
Habley and fifty percent (50%) for the U.S. Medical.

         If Habley shall fail to institute suit to enjoin such infringement
within one hundred and twenty (120) days after written notification thereof by
U.S. Medical, then U.S. Medical shall have the right, at its sole and complete

period in which U.S. Medical is bringing suit in accordance with this Paragraph
9, U.S. Medical may apply up to fifteen percent (15%) of the royalties payable

         If U.S. Medical shall recover costs, expenses and/or damages, from the
infringer, such recovery shall be retained by U.S. Medical to the extent of U.S.
Medical's reasonable costs and expenses actually incurred and the remainder of
any such recovery shall be shared equally between U.S. Medical and Habley up to,
but not further than, Habley's loss of royalty under this Paragraph 9. The
recovery in excess of Habley's loss of royalty shall be shared by the parties
fifty percent (50%) for Habley and fifty percent (50%) for U.S. Medical. Habley
shall cooperate with U.S. Medical to a reasonable extent requested by U.S.
Medical and Habley shall have the right to be represented by legal counsel of
its choice at its sole expense during the conduct of such infringement suit.

10.0     COMPETITIVE PRODUCTS. U.S. Medical represents and warrants to Habley

similar purpose as any of the Products and that it has no intention or plans at
the present time to make, sell or have any rights in any product which is used
for the same or similar purpose as any of the Products. If U.S. Medical shall
make, have made for it, use and/or sell or obtain any rights in or to any safety
syringe product which is used for the same or similar purpose as any of the
Products then all licenses and rights granted to U.S. Medical in this Agreement

for the balance of the Term, in which case U.S. Medical shall continue to pay to
Habley all royalties pursuant to Paragraphs 4.1 through 4.4.

        3.2 Delay in Possession. Notwithstanding said commencement date, if for
any reason Lessor cannot deliver possession of the Premises to Lessee on said
date, Lessor shall not be subject to any liability therefor, nor shall such
failure affect the validity of this Lease or the obligations of Lessee
hereunder or extend the term hereof, but in such case, Lessee shall not be
obligated to pay rent or perform any other obligation of Lessee under the terms
of this Lease, except as may be otherwise provided in this Lease, until
possession of the Premises is tendered to Lessee; provided, however, that if
Lessor shall not have delivered possession of the Premises within sixty (60)
days from said commencement date, Lessee may, at Lessee's option, by notice
in writing to Lessor within ten (10) days thereafter, cancel this Lease, in
which event the parties shall be discharged from all obligations hereunder;
provided further, however, that if such written notice of Lessee is not
received by Lessor within said ten (10) day period, Lessee's right to cancel
this Lease hereunder shall terminate and be of no further force or effect.

        3.3 Early Possession. If Lessee occupies the Premises prior to said
commencement date, such occupancy shall be subject to all provisions of this
Lease, such occupancy shall not advance in the termination date. See Addendum
Paragraph 4.

unloading areas, trash areas, roadways, sidewalks, walkways, parkways,

<PAGE>   2

        (ee) Security services:
        (ff) Any other service to be provided by Lessor that is elsewhere in
this Lease stated to be an "Operating Expense;"
     (ii) Any deductible portion of an insured loss concerning any of the items
or matters described in this paragraph 4.2;
     (iii) The cost of the premiums for the liability and property insurance
policies to be maintained by Lessor under paragraph 8 hereof;
     (iv) The amount of the real property tax to be paid by Lessor under
paragraph 10.1 hereof;
     (v)  The cost of water, gas and electricity to service the Common Areas.
  (c) The inclusion of the improvements, facilities and services set forth in
paragraph 4.2(b)(i) of the definition of Operating Expenses shall not be deemed
to impose an obligation upon Lessor to either have said improvements or
facilities or to provide those services unless the Industrial Center already
has the same. Lessor already provides the services, or Lessor has agreed
elsewhere in this Lease to provide the same or some of them.
  (d) Lessee's Share of Operating Expenses shall be payable by Lessee within
ten (10) days after a reasonably detailed statement of actual expenses is
presented to Lessee by Lessor. At Lessor's option, however, an amount may be
estimated by Lessor from time to time of Lessee's Share of annual Operating
Expenses and the same shall be payable monthly or quarterly, as Lessor shall
designate, during each twelve-month period of the Lease term, on the same day
as the Base Rent is due hereunder. In the event that Lessee pays Lessor's
estimate of Lessee's Share of Operating Expenses as aforesaid. Lessor shall
deliver to Lessee within sixty (60) days after the expiration of each calendar
year a reasonably detailed statement showing Lessee's Share of the actual
Operating Expenses incurred during the preceding year. If Lessee's payments
under this paragraph 4.2(d) during said preceding year exceed Lessee's Share as
indicated on said statement, Lessee shall be entitled to credit the amount of
such overpayment against Lessee's Share of Operating Expenses next falling due.
If Lessee's payments under this paragraph during said preceding year were less
than Lessee's Share as indicated on said statement, Lessee shall pay to Lessor
the amount of the deficiency within ten (10) days after delivery by Lessor to
Lessee of said statement.

5. Security Deposit.  Lessee shall deposit with Lessor upon execution hereof
$60,000 as security for Lessee's faithful performance of Lessee's obligations
hereunder. If lessee fails to pay rent or other charges due hereunder, or
otherwise defaults with respect to any provision of this Lease, Lessor may use,
apply or retain all or any portion of said deposit for the payment of any rent
or other charge in default or for the payment of any other sum to which Lessor
may become obligated by reason of Lessee's default, or to compensate Lessor for
any loss or damage which Lessor may suffer thereby. If Lessor so uses or
applies all or any portion of said deposit, Lessee shall within ten (10) days
after written demand therefor deposit cash with Lessor in an amount sufficient
to restore said deposit to the full amount then required of Lessee. If the
monthly rent shall, from time to time, increase during the term of this Lease,
Lessee shall, at the time of such increase, deposit with Lessor additional
money as a security deposit so that the total amount of the security deposit
held by Lessor shall at all times bear the same proportion to the then current
Base Rent as the initial security deposit bears to the initial Base Rent set
forth in paragraph 4. Lessor shall not be required to keep said security
deposit separate from its general accounts. If Lessee performs all of Lessee's
obligations hereunder, said deposit, or so much thereof as has not theretofore
been applied by Lessor, shall be returned, without payment of interest or other
increment for its use, to Lessee (or, at Lessor's option, to the last assignee,
if any, of Lessee's interest hereunder) at the expiration of the term hereof,
and after Lessee has vacated the Premises. No trust relationship is created
herein between Lessor and Lessee with respect to said Security Deposit.

6. Use.  See Addendum Paragraph 7.

   6.1  Use.

  6.2   Compliance with Law.

        (a) Lessor warrants to Lessee that to the actual knowledge of Lessor's
officers the Premises, in the state existing on the date that the Lease term
commences, but without regard to the use for which Lessee will occupy the
Premises, does not violate any covenants or restrictions of record, or any
applicable building code, regulation or ordinance in effect on such Lease term
commencement date. In the event it is determined that this warranty has been
violated, then it shall be the obligation of the Lessor, after written notice
from Lessee, to promptly, at Lessor's sole cost and expense, rectify any such
violation. In the event Lessee does not give to Lessor written notice of the
violation of this warranty within six months from the date that the Lease term
commences, the correction of same shall be the obligation of the Lessee at
Lessee's sole cost. The warranty contained in this paragraph 6.2(a) shall be of
no force or effect if, prior to the date of this Lease, Lessee was an owner or
occupant of the Premises and, in such event, Lessee shall correct any such
violation at Lessee's sole cost.

        (b) Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
expense, promptly comply with all applicable statutes, ordinances, rules,
regulations, orders, covenants and restrictions of record, and requirements of
any fire insurance underwriters or rating bureaus, now in effect or which may
hereafter come into effect, whether or not they reflect a change in policy from
that now existing, during the term or any part of the term hereof, relating in
any manner to the Premises and the occupation and use by Lessee of the Premises
and of the Common Areas. Lessee shall not use nor permit the use of the
Premises or the Common Areas in any manner that will tend to create waste or a
nuisance or shall tend to disturb other occupants of the Industrial Center.

  6.3  Condition of Premises. See Addendum Paragraph 8.

        (a)  Lessor shall deliver the Premises to Lessee clean and free of
debris on the Lease commencement date (unless Lessee is already in possession)
and Lessor warrants to Lessee that the plumbing, lighting, air conditioning,
heating, TES System and loading doors in the Premises shall be in good
operating condition on the Lease commencement date. In the event that it is
determined that this warranty has been violated, then it shall be the
obligation of Lessor, after receipt of written notice from Lessee setting forth
with specificity the nature of the violation, to promptly, at Lessor's sole
cost, rectify such violation. Lessee's failure to give such written notice to
Lessor within 90 days after the Lease commencement date shall cause the
conclusive presumption that Lessor has complied with all of Lessor's
obligations hereunder.

        (b) Except as otherwise provided in this Lease, Lessee hereby accepts
the Premises in their condition existing as of the Lease commencement date or
the date that Lessee takes possession of the Premises, whichever is earlier,
subject to all applicable zoning, municipal, county and state laws, ordinances
and regulations governing and regulating the use of the Premises, and any
covenants or restrictions of record, and accepts this Lease subject thereto and
to all matters disclosed thereby and by any exhibits attached hereto. Lessee
acknowledges that neither Lessor nor Lessor's agent has made any representation
or warranty as to the present or future suitability of the Premises for the
conduct of Lessee's business.

7. Maintenance, Repairs, Alterations and Common Area Services. See Addendum
Paragraph 9.

   7.1  Lessor's Obligations.  Subject to the provisions of paragraphs 4.2
(Operating Expenses), 6(Use), 7.2 (Lessee's Obligations) and 9 (Damage or
Destruction) and except for damage caused by any negligent or intentional act
or omission of Lessee, Lessee's employees, suppliers, shippers, customers, or
invitees, in which event Lessee shall repair the damage, Lessor, at Lessor's
expense, subject to reimbursement pursuant to paragraph 4.2, shall keep in good
condition and repair the foundations, exterior walls, structural condition of
interior bearing walls, and roof of the Premises, as well as the parking lots,
walkways, driveways, landscaping, fences, signs and utility installations of
the Common Areas and all parts thereof. Lessor shall not, however, be obligated
to paint the exterior or interior surface of exterior walls, nor shall Lessor
be required to maintain, repair or replace windows, doors or plate glass of the
Premises. Lessor shall have no obligation to make repairs under this paragraph
7.1 until a reasonable time after receipt of written notice from Lessee of the
need for such repairs. Lessee expressly waives the benefits of any statute now
or hereafter in effect which would otherwise afford Lessee the right to make
repairs at Lessor's expense or to terminate this Lease because of Lessor's
failure to keep the Premises in good order, condition and repair. Lessor shall
not be liable for damages or loss of any kind or nature by reason of Lessor's
failure to furnish any Common Area Services when such failure is caused by
accident, breakage, repairs, strikes, lockout, or other labor disturbances or
disputes of any character, or by any other cause beyond the reasonable control
of Lessor.

  7.2  Lessee's Obligations. See Addendum Paragraph 10.

        (a) Subject to the provisions of paragraphs 6 (Use), 7.1 (Lessor's
Obligations), and 9  (Damage or Destruction), Lessee, at Lessee's expense,
shall keep in good order, condition and repair the Premises and every part
thereof (whether or not the damaged portion of the Premises or the means of
repairing the same are reasonably or readily accessable to Lessee) including,
without limiting the generality of the foregoing, all plumbing, heating,
ventilating and air conditioning systems (Lessee shall procure and maintain, at
Lessee's expense, a ventilating and air conditioning system maintenance
contract), electrical and lighting facilities and equipment within the
Premises, fixtures, interior walls and interior surfaces of exterior walls,
ceilings, windows, doors, plate glass, and skylights located within the
Premises. Lessor reserves the right to procure and maintain the ventilating and
air conditioning system maintenance contract and if Lessor so elects, Lessee
shall reimburse Lessor, upon demand, for the cost thereof.

        (b)  If Lessee fails to perform Lessee's obligations under this
paragraph 7.2 or under any other paragraph of this Lease, Lessor may enter upon
the Premises after ten (10) days' prior written notice to Lessee (except in the
case of emergency, in which no notice shall be required), perform such
obligations on Lessee's behalf and put the Premises in good order, condition
and repair, and the cost thereof together with interest thereon at the maximum
rate then allowable by law shall be due and payable as additional rent to
Lessor together with Lessee's next Base Rent installment.

        (c)  On the last day of the term hereof, or on any sooner termination,
Lessee shall surrender the Premises to Lessor in good condition, ordinary wear
and tear and any casualty or other condition which is not the obligation of
Lessee hereunder excepted, clean and free of debris. Any damage or deterioration
of the Premises shall not be deemed ordinary wear and tear if the same could
have been prevented by good maintenance practices. Lessee shall repair any
damage to the Premises occasioned by the installation or removal of Lessee's
trade fixtures, alterations, furnishings and equipment. Notwithstanding anything
to the contrary otherwise stated in this Lease, Lessee shall leave the air
lines, power panels, electrical distribution systems, lighting fixtures, space
heaters, air conditioning, plumbing and fencing on the Premises in good
operating condition.

     
  7.3  Alterations and Additions.  See Addendum Paragraph 11.

        (a)  Lessee shall not, without Lessor's prior written consent make any
alterations, improvements, additions, or Utility Installations in, on or about
the Premises, or the Industrial Center, except for nonstructural alterations to
the Premises not exceeding $10,000 for any cost or group of related costs
during the term of this Lease. In any event, whether or not in excess of
$10,000, Lessee shall make no change or alteration to the 
<PAGE>   3
exterior of the Premises nor the exterior of the Building nor the Industrial
Center without Lessor's prior written consent. As used in this paragraph 7.3 the
term "Utility Installation" shall mean carpeting, window coverings, air lines,
power panels, electrical distribution systems, lighting fixtures, space
heaters, air conditioning, plumbing, and fencing. Lessor may require that Lessee
remove any or all of said alterations, improvements, additions or Utility
Installations at the expiration of the term, and restore the Premises and the
Industrial Center to their prior condition.  As to any work or related items of
work costing in excess of $50,000 and/or including the initial tenant
improvement work. Lessee will insure that general contractor and
sub-contractor will provide lien releases to lessor. Lessor may require 
Lessee to provide Lessor, at Lessee's sole cost and expense, a lien and
completion bond in an amount equal to one and one-half times the estimated cost
of such improvements, to insure Lessor against any liability for mechanic's and
materialmen's liens and to insure completion of the work. Should Lessee make
any alterations, improvements, additions or Utility Installations without the
prior approval of Lessor. Lessor may, at any time during the term of this Lease,
require that Lessee remove any or all of the same.

           (b) Any alterations, improvements, additions or Utility Installations
in or about the Premises or the Industrial Center that Lessee shall desire to
make and which requires the consent of the Lessor shall be presented to Lessor
in written form, with proposed detailed plans. If Lessor shall give its
consent, the consent shall be deemed conditioned upon Lessee acquiring a permit
to do so from appropriate governmental agencies, the furnishing of a copy
thereof to Lessor prior to the commencement of the work and the compliance by
Lessee of all conditions of said permit in a prompt and expeditious manner.

           (c) Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, or the Industrial Center, or any
interest therein. Lessee shall give Lessor not less than ten (10) days' notice
prior to the commencement of any work in the Premises, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises or the
Building as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises or the Industrial Center, upon the
condition that if Lessor shall require, Lessee shall furnish to Lessor a surety
bond satisfactory to Lessor in an amount equal to such contested lien claim or
demand indemnifying Lessor against liability for the same and holding the
Premises and the Industrial Center free from the effect of such lien or claim.
In addition, Lessor may require Lessee to pay Lessor's attorneys fees and costs
in participating in such action if Lessor shall decide it is to Lessor's best
interest to do so.

           (d) All alterations, improvements, additions and Utility
Installations (whether or not such Utility Installations constitute trade
fixtures of Lessee), which may be made on the Premises, shall be the property of
Lessor and shall remain upon and be surrendered with the Premises at the
expiration of the Lease term, unless Lessor requires their removal pursuant to
paragraph 7.3(a). Notwithstanding the provisions of this paragraph 7.3(d),
Lessee's machinery and equipment, other than that which is affixed to the
Premises so that it cannot be removed without material damage to the Premises,
and other than Utility Installations, shall remain the property of Lessee and
may be removed by Lessee subject to the provisions of paragraph 7.2.

        7.4 Utility Additions. Lessor reserves the right to install new or
additional utility facilities throughout the Building and the Common Areas for
the benefit of Lessor or Lessee, or any other lessee of the Industrial Center,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, security systems, communication systems, and fire protection and
detection systems, so long as such installations do not unreasonably interfere
with Lessee's use of the Premises.

8. Insurance; Indemnity.

        8.1 Liability Insurance -- Lessee. Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease a policy of Combined
Single Limit Bodily Injury and Property Damage insurance insuring Lessee and
Lessor against any liability arising out of the use, occupancy or maintenance
of the Premises and the Industrial Center. Such insurance shall be in an amount
not less than $500,000.00 per occurrence. The policy shall insure performance
by Lessee of the indemnity provisions of this paragraph 8. The limits of said
insurance shall not, however, limit the liability of Lessee hereunder.

        8.2 Liability Insurance -- Lessor. Lessor shall obtain and keep in
force during the term of this Lease a policy of Combined Single Limit Bodily
Injury and Property Damage Insurance, insuring Lessor, but not Lessee, against
any liability arising out of the ownership, use, occupancy or maintenance of
the Industrial Center in an amount not less than $500,000.00 per occurrence.

        8.3 Property Insurance. Lessor shall obtain and keep in force during
the term of this Lease a policy or policies of insurance covering loss or
damage to the Industrial Center improvements, but not Lessee's personal
property, fixtures, equipment or tenant improvements, in an amount not to
exceed the full replacement value thereof, as the same may exist from time to
time, providing protection against all perils included within the
classification of fire, extended coverage, vandalism, malicious mischief, flood
(in the event same is required by a lender having a lien on the Premises)
special extended perils ("all risk", as such term is used in the insurance
industry), plate glass insurance and such other insurance as Lessor deems
advisable. In the event that the Premises shall suffer an insured loss as
defined in paragraph 9.1(g) hereof, the deductible amounts under the casualty
insurance policies relating to the Premises shall be paid by Lessee.

        8.4 Payment of Premium Increase.

            (a) After the term of this Lease has commenced, Lessee shall not be
responsible for paying Lessee's Share of any increase in the property insurance
premium for the Industrial Center specified by Lessor's insurance carrier as
being caused by the use, acts or omissions of any other lessee of the
Industrial Center, or by the nature of such other lessee's occupancy which
create an extraordinary or unusual risk.

            (b) Lessee, however, shall pay the entirety of an increase in the
property insurance premium for the Industrial Center over what it was
immediately prior to the commencement of the term of this Lease if the increase
is specified by Lessor's insurance carrier as being caused by the nature of
Lessee's occupancy or any act or omission of Lessee.

        8.5 Insurance Policies. Insurance required hereunder shall be in
companies holding a "General Policyholders Rating" of at least B plus, or such
other rating as may be required by a lender having a lien on the Premises, as
set forth in the most current issue of "Best's Insurance Guide." Lessee shall
not do or permit to be done anything which shall invalidate the insurance
policies carried by Lessor, Lessee shall delivery to Lessor copies of liability
insurance policies required under paragraph 8.1 or certificates evidencing the
existence and amounts of such insurance within seven (7) days after the
commencement date of this Lease. No such policy shall be cancellable or subject
to reduction of coverage or other modification except after thirty (30) days
prior written notice to Lessor. Lessee shall at least thirty (30) days prior to
the expiration of such policies, furnish Lessor with renewals or "binders"
thereof.

        8.6 Waiver of Subrogation. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right to recovery against the other
for loss or damage arising out of or incident to the perils insured against
which perils occur in, on or about the Premises, whether due to the negligence
of Lessor or Lessee or their agents, employees, contractors and/or invitees.
Lessee and Lessor shall, upon obtaining the policies of insurance required give
notice to the insurance carrier or carriers that the foregoing mutual waiver of
subrogation is contained in this Lease.

        8.7 Indemnity. Lessee shall indemnify and hold harmless Lessor from and
against any and all claims arising from Lessee's use of the Industrial Center,
or from the conduct of Lessee's business or from any activity, work or things
done, permitted or suffered by Lessee in or about the Premises or elsewhere and
shall further indemnify and hold harmless Lessor from and against any and all
claims arising from any breach or default in the performance of any obligation
on Lessee's part to be performed under the terms of this Lease, or arising from
any act or omission of Lessee, or any of Lessee's agents, contractors, or
employees, and from and against all costs, attorney's fees, expenses and
liabilities incurred in the defense of any such claim or any action or
proceeding brought thereon; and in case any action or proceeding be brought
against Lessor by reason of any such claim, Lessee upon notice from Lessor shall
defend the same at Lessee's expense by counsel reasonably satisfactory to Lessor
and lessor shall cooperate with Lessee in such defense. Lessee, as a material
part of the consideration to Lessor, hereby assumes all risk of damage to
property of Lessee or injury to persons, in, upon or about the Industrial Center
arising from any cause and Lessee hereby waives all claims in respect thereof
against Lessor. See Addendum Paragraph 13.

        8.8 Exemption of Lessor from Liability. Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for damage to the goods, wares, merchandise or other property of
Lessee, Lessee's employees, invitees, customers, or any other person in or
about the Premises or the Industrial Center, nor shall Lessor be liable for
injury to the person of Lessee. Lessee's employees, agents or contractors,
whether such damage or injury is caused by or results from fire, steam,
electricity, gas, water or rain, or from the breakage, leakage, obstruction or
other defects of pipes, sprinklers, wires, appliances, plumbing, air
conditioning or lighting fixtures, or from any other cause, whether said damage
or injury results from conditions arising upon the Premises or upon other
portions of the Industrial Center, or from other sources or places and
regardless of whether the cause of such damage or injury or the means of
repairing the same is inaccessible to Lessee. Lessor shall not be liable for
any damages arising from any act or neglect of any other lessee, occupant or
user of the Industrial Center, nor from the failure of Lessor to enforce the
provisions of any other lease of the Industrial Center.

<PAGE>   4
                (g)  "Insured Loss" shall mean damage or destruction which was 
covered by an event required to be covered by the insurance described in
paragraph 8. The fact that an Insured Loss has a deductible amount shall not
make the loss an uninsured loss.

                (h)  "Replacement Cost" shall mean the amount of money 
necessary to be spent in order to repair or rebuild the damaged area to the
condition that existed immediately prior to the damage occurring excluding all

                (a)  Insured Loss: Subject to the provisions of paragraphs 9.4
and 9.5, if at any time during the term of this Lease there is damage which is
an Insured Loss and which falls into the classification of either Premises
Partial Damage or Premises Building Partial Damage, then Lessor shall, but only
to the extent of actual insurance proceeds, repair such damage to the Premises,
but not Lessee's fixtures, equipment or tenant improvements, as soon as
reasonably possible and this Lease shall continue in full force and effect.

                (b)  Uninsured Loss: Subject to the provisions of paragraphs
9.4 and 9.5, if at any time during the term of this Lease there is damage which
is not an Insured Loss and which falls within the classification of Premises
Partial Damage or Premises Building Partial Damage, unless caused by a
negligent or willful act of Lessee (in which event Lessee shall make the
repairs at Lessee's expense), which damage prevents Lessee from using the
Premises. Lessor may at Lessor's option either (i) repair such damage as soon as
reasonably possible at Lessor's expense, in which event this Lease shall
continue in full force and effect, or (ii) give written notice to Lessee within
thirty (30) days after the date of the occurrence of such damage of Lessor's
intention to cancel and terminate this Lease as of the date of the occurrence
of such damage. In the event Lessor elects to give such notice of Lessor's
intention to cancel and terminate this Lease. Lessee shall have the right
within ten (10) days after the receipt of such notice to give written notice to
Lessor of Lessee's intention to repair such damage at Lessee's expense, without
reimbursement from Lessor, in which event this Lease shall continue in full
force and effect, and Lessee shall proceed to make such repairs as soon as

any time during the term of this Lease there is damage, whether or not it is an
Insured Loss, and which falls into the classifications of either (i) Premises

Industrial Center Buildings Total Destruction, then Lessor may at Lessor's
option either (i) repair such damage or destruction, but not Lessee's fixtures,
equipment or tenant improvements, as soon as reasonably possible at Lessor's
expense, and this Lease shall continue in full force and effect, or (ii) give
written notice to Lessee within thirty (30) days after the date of occurrence
of such damage of Lessor's intention to cancel and terminate this Lease, in
which case this Lease shall be cancelled and terminated as of the date of the
occurrence of such damage.

        9.4     DAMAGE NEAR END OF TERM.

                (a)  Subject to paragraph 9.4(b), if at any time during the
last six months of the term of this Lease there is substantial damage, whether

as of the date of occurrence of such damage by giving written notice to Lessee
of Lessor's election to do so within 30 days after the date of occurrence of
such damage.

                (b)  Notwithstanding paragraph 9.4(a), in the event that Lessee
has an option to extend or renew this Lease, and the time within which said
option may be exercised has not yet expired, Lessee shall exercise such option,
if it is to be exercised at all, no later than twenty (20) days after the
occurrence of an Insured Loss falling within the classification of Premises
Partial Damage during the last six months of the term of this Lease. If Lessee
duly exercises such option during said twenty (20) day period, Lessor shall, to
the extent otherwise required under Paragraph 9.2(a) at Lessor's expense,
repair such damage, but not Lessee's fixtures, equipment or tenant
improvements, as soon as reasonably possible and this Lease shall continue in
full force and effect. If Lessee fails to exercise such option during said
twenty (20) day period, then Lessor may at Lessor's option terminate and cancel
this Lease as of the expiration of said twenty (20) day period by giving
written notice to Lessee of Lessor's election to do so within ten (10) days
after the expiration of said twenty (20) day period, notwithstanding any term
or provision in the grant of option to the contrary.

        9.5     ABATEMENT OF RENT; LESSEE'S REMEDIES.

                (a)  Lessee shall have no claim against Lessor for any damage
suffered by reason of any damage, destruction, repair or restoration.

                (b)  If Lessor shall be obligated to repair or restore the
Premises under the provisions of this paragraph 9 and shall not commence such
repair or restoration within ninety (90) days after such obligation shall
accrue and Lessor has obtained immediate access to sufficient insurance
proceeds to complete the repair and restoration. Lessee may at Lessee's option
cancel and terminate this Lease by giving Lessor written notice of Lessee's
election to do so at any time prior to the commencement of such repair or
restoration. In such event this Lease shall terminate as of the date of such
notice.

Lease pursuant to this paragraph 9, an equitable adjustment shall be made
concerning advance rent and any advance payments made by Lessee to Lessor.

        9.7     WAIVER.  Lessor and Lessee waive the provisions of any statute

10.     REAL PROPERTY TAXES.

        10.1    PAYMENT OF TAXES.  Lessor shall pay the real property tax, as
defined in paragraph 10.3, applicable to the Industrial Center subject to
reimbursement by Lessee of Lessee's Share of such taxes in accordance with the
provisions of paragraph 4.2, except as otherwise provided in paragraph 10.2.

        10.2    ADDITIONAL IMPROVEMENTS.  Lessee shall not be responsible for
paying Lessee's Share of any increase in real property tax specified in the tax
assessor's records and work sheets as being caused by additional improvements
placed upon the Industrial Center by other lessees or by Lessor for the
exclusive enjoyment of such other lessees. Lessee shall, however, pay to Lessor
at the time that Operating Expenses are payable under paragraph 4.2(c) the
entirety of any increase in real property tax if assessed solely by reason of
additional improvements placed upon the Premises by Lessee or at Lessee's
request. 

        10.3    DEFINITION OF "REAL PROPERTY TAX."  As used herein, the term
"real property tax" shall include any form of real estate tax or assessment,
general, special, ordinary or extraordinary, and any license fee, commercial
rental tax, improvement bond or bonds, levy or tax (other than inheritance,
personal income or estate taxes) imposed on the Industrial Center or any
portion thereof by any authority having the direct or indirect power to tax,
including any city, county, state or federal government, or any school,
agricultural, sanitary, fire, street, drainage or other improvement district
thereof, as against any legal or equitable interest of Lessor in the Industrial
Center or in any portion thereof, as against Lessor's right to rent or other
income therefrom, and as against Lessor's business of leasing the Industrial
Center. The term "real property tax" shall also include any tax, fee, levy,
assessment or charge (i) in substitution of, partially or totally, any tax, fee,
levy assessment or charge hereinabove included within the definition of "real
property tax," or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a service or
right not charged prior to June 1, 1978, or, if previously charged, has been
increased since June 1, 1978, or (iv) which is imposed as a result of a
transfer, either partial or total, of Lessor's interest in the Industrial Center
or which is added to a tax or charge hereinbefore included within the definition
of real property tax by reason of such transfer, or (v) which is imposed by
reason of this transaction, any modifications or changes hereto, or any
transfers hereof.

        10.4    JOINT ASSESSMENT.  If the Industrial Center is not separately
assessed, Lessee's Share of the real property tax liability shall be an
equitable proportion of the real property taxes for all of the land and
improvements included within the tax parcel assessed, such proportion to be
determined by Lessor from the respective valuations assigned in the assessor's
work sheets or such other information as may be reasonably available. Lessor's
reasonable determination thereof, in good faith, shall be conclusive.

        10.5    PERSONAL PROPERTY TAXES.

                (a)  Lessee shall pay prior to delinquency all taxes assessed
against and levied upon trade fixtures, furnishings, equipment and all other
personal property of Lessee contained in the Premises or elsewhere. When
possible, Lessee shall cause said trade fixtures, furnishings, equipment and
all other personal property to be assessed and billed separately from the real
property of Lessor.

                (b)  If any of Lessee's said personal property shall be
assessed Lessor's real property, Lessee shall pay to Lessor the taxes
attributable to Lessee within ten (10) days after receipt of a written
statement setting forth the taxes applicable to Lessee's property.

11.     UTILITIES.  Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon. If any such services are not separately metered to the
Premises. Lessee shall pay at Lessor's option, either Lessee's Share or a
reasonable proportion to be determined by Lessor of all charges jointly metered
with other premises in the Building.

12.     ASSIGNMENT AND SUBLETTING. See Addendum Paragraph 15.

        12.1    LESSOR'S CONSENT REQUIRED.  Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease without the need for notice to Lessee under paragraph 13.1.

        12.2    LESSEE AFFILIATE.  Notwithstanding the provisions of paragraph
12.1 hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by
or is under common control with Lessee, or to any corporation resulting from
the merger or consolidation with Lessee, or to any person or entity which
acquires all the assets of Lessee as a going concern of the business that is
being conducted on the Premises, all of which are referred to as "Lessee
Affiliate," provided that before such assignment shall be effective said
assignee shall assume, in full, the obligations of Lessee under this Lease. Any
such assignment shall not, in any 
<PAGE>   5
way, affect or limit the liability of Lessee under the terms of this Lease even
if after such assignment or subletting the terms of this Lease are materially
changed or altered without the consent of Lessee, the consent of whom shall not
be necessary.

        12.3  TERMS AND CONDITIONS OF ASSIGNMENT.  Regardless of Lessor's
consent, no assignment shall release Lessee of Lessee's obligations hereunder
or alter the primary liability of Lessee to pay the Base Rent and Lessee's
Share of Operating Expenses, and to perform all other obligations to be
performed by Lessee hereunder. Lessor may accept rent from any person other
than Lessee pending approval or disapproval of such assignment. Neither a delay
in the approval or disapproval of such assignment nor the acceptance of rent
shall constitute a waiver or estoppel of Lessor's right to exercise its
remedies for the breach of any of the terms or conditions of this paragraph 12
or this Lease. Consent to one assignment shall not be deemed consent to any
subsequent assignment. In the event of default by any assignee of Lessee or any
successor of Lessee, in the performance of any of the terms hereof, Lessor may
proceed directly against Lessee without the necessity of exhausting remedies
against said assignee. Lessor may consent to subsequent assignments of this
Lease or amendments or modifications to this Lease with assignees of Lessee,
without notifying Lessee, or any successor of Lessee, and without obtaining its
or their consent thereto and such action shall not relieve Lessee of liability
under this Lease.

     12.4  TERMS AND CONDITIONS APPLICABLE TO SUBLETTING.  Regardless of
Lessor's consent, the following terms and conditions shall apply to any
subletting by Lessee of all or any part of the Premises and shall be included
in subleases:

           (a)  Lessee hereby assigns and transfers to Lessor all of
Lessee's interest in all rentals and income arising from any sublease
heretofore or hereafter made by Lessee, and Lessor may collect such rent and
income and apply same toward Lessee's obligations under this Lease; provided,
however, that until a default shall occur in the performance of Lessee's
obligations under this Lease, Lessee may receive, collect and enjoy the rents
accruing under such sublease. Lessor shall not, by reason of this or any other
assignment of such sublease to Lessor nor by reason of the collection of the
rents from a sublessee, be deemed liable to the sublessee for any failure of
Lessee to perform and comply with any of Lessee's obligations to such sublessee
under such sublease. Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a default
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents due and to become due under the sublease. Lessee agrees that
such sublessee shall have the right to rely upon any such statement and request
from Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against such sublessee or Lessor for any such
rents so paid by said sublessee to Lessor.

           (b) No sublease entered into by Lessee shall be effective unless
and until it has been approved in writing by Lessor. In entering into any
sublease, Lessee shall use only such form of sublease as is satisfactory to
Lessor, and once approved by Lessor, such sublease shall not be changed or
modified without Lessor's prior written consent. Any sublessee shall, by reason
of entering into a sublease under this Lease, be deemed, for the benefit of
Lessor, to have assumed and agreed to conform and comply with each and every
obligation herein to be performed by Lessee other than such obligations as are
contrary to or inconsistent with provisions contained in a sublease to which
Lessor has expressly consented in writing.

           (c)  If Lessee's obligations under this Lease have been
guaranteed by third parties, then a sublease, and Lessor's consent thereto,
shall not be effective unless said guarantors give their written consent to
such sublease and the terms thereof.

           (d)  The consent by Lessor to any subletting shall not release
Lessee from its obligations or alter the primary liability of Lessee to pay the
rent and perform and comply with all of the obligations of Lessee to be
performed under this Lease.

           (e)  The consent by Lessor to any subletting shall not constitute
a consent to any subsequent subletting by Lessee to any assignment or
subletting by the sublessee. However, Lessor may consent to subsequent
sublettings and assignments of the sublease or any amendments or modifications
thereto without notifying Lessee or anyone else liable on the Lease or sublease
and without obtaining their consent and such action shall not relieve such
persons from liability.

           (f)  In the event of any default under this Lease, Lessor may
proceed directly against Lessee, any guarantors or any one else responsible for
the performance of this Lease, including the sublessee, without first
exhausting Lessor's remedies against any other person or entity responsible
therefor to Lessor, or any security held by Lessor or Lessee.

           (g)  In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Lessee or for any other prior defaults of Lessee
under such sublease.

           (h)  Each and every consent required of Lessee under a sublease
shall also require the consent of Lessor.

           (i)  No sublessee shall further assign or sublet all or any part
of the Premises without Lessor's prior written consent.

           (j)  Lessor's written consent to any subletting of the Premises
by Lessee shall not constitute an acknowledgement that no default then exists
under this Lease of the obligations to be performed by Lessee nor shall such
consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

           (k)  With respect to any subletting to which Lessor has
consented, Lessor agrees to deliver a copy of any notice of default by Lessee
to the sublessee. Such sublessee shall have the right to cure a default of
Lessee within ten (10) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset
from and against Lessee for any such defaults cured by the sublessee.

     12.5  ATTORNEY'S FEES.  In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorneys fees incurred in connection
therewith, such attorneys fees not to exceed $350.00 for each such request.

13.  DEFAULT; REMEDIES.

     13.1  DEFAULT.  The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

           (a)  The vacating or abandonment of the Premises by Lessee.

           (b)  The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, where such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph.

           (c)  Except as otherwise provided in this Lease, the failure by
Lessee to observe or perform any of the covenants, conditions or provisions of
this Lease to be observed or performed by Lessee, other than described in
paragraph (b) above, where such failure shall continue for a period of thirty
(30) days after written notice thereof from Lessor to Lessee; provided,
however, that if the nature of Lessee's noncompliance is such that more than
thirty (30) days are reasonably required for its cure, then Lessee shall not be
deemed to be in default if Lessee commenced such cure within said thirty (30)
day period and thereafter diligently prosecutes such cure to completion. To the
extent permitted by law, such thirty (30) day notice shall constitute the sole
and exclusive notice required to be given to Lessee under applicable Unlawful
Detainer statutes.

           (d)  (i) The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becomes a "debtor" as
defined in 11 U.S.C. Section 101 or any successor statute thereto (unless, in
the case of a petition filed against Lessee, the same is dismissed within sixty
(60) days); (iii) the appointment of a trustee or receiver to take possession
of substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within
thirty (30) days; or (iv) the attachment, execution or other judicial seizure
of substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days. In the event that any provision of this paragraph 13.1(d) is contrary to
any applicable law, such provision shall be of no force or effect.

           (e)  The discovery by Lessor that any financial statement given to
Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any
successor in interest of Lessee or any guarantor of Lessee's obligation
hereunder, was materially false.

     13.2  REMEDIES.  In the event of any such material default by Lessee,
Lessor may at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default:

           (a)  Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In
such event Lessor shall be entitled to recover from Lessee all damages incurred
by Lessor by reason of Lessee's default including, but not limited to, the cost
of recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the Premises, reasonable attorney's
fees, and any real estate commission actually paid; the worth at the time of
award by the court having jurisdiction thereof of the amount by which the
unpaid rent for the balance of the term after the time of such award exceeds
the amount of such rental loss for the same period that Lessee proves could be
reasonably avoided; that portion of the leasing commission paid by Lessor
pursuant to paragraph 15 applicable to the unexpired term of this Lease.

           (b)  Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent
as it becomes due hereunder.

           (c)  Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

     13.3  DEFAULT BY LESSOR.  Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but
in no event later than thirty (30) days after written notice by Lessee to
Lessor and to the holder of any first mortgage or deed of trust covering the
Premises whose name and address shall have theretofore been furnished to Lessee
in writing, specifying wherein Lessor has failed to perform such obligation;
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default if Lessor commences performance within such thirty (30) day period and
thereafter diligently prosecutes the same to completion.

        13.4  LATE CHARGES.  Lessee hereby acknowledges that late payment by
Lessee to Lessor of Base Rent. Lessee's Share of Operating Expenses or
other sums due hereunder will cause Lessor to incur costs not contemplated by
this Lease, the exact amount of which will be extremely difficult to ascertain.
Such costs include, but are not limited to, processing and accounting charges,
and late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Property. Accordingly, if any installment of Base Rent,
Operating Expenses, or any other sum due from Lessee shall not be received by
Lessor or Lessor's designee within ten (10) days after such amount shall be
due, then, without any requirement for notice to Lessee, Lessee shall pay to
Lessor a late charge equal to 6% of such overdue amount. The parties hereby
agree that such late charge represents a fair and reasonable estimate of the
costs Lessor will incur by reason of late payment by Lessee. Acceptance of such
late charge by Lessor shall in no event constitute a waiver of Lessee's default
with respect to such overdue amount, nor prevent Lessor from exercising any of
the other rights and remedies granted hereunder. In the event that a late
charge is payable hereunder, whether or not collected, for three (3)
consecutive installments of any of the aforesaid monetary obligations of
Lessee, then Base Rent shall automatically become due and payable quarterly in
advance, rather than monthly, notwithstanding paragraph 4.1 or any other
provision of this Lease to the contrary.

14.  CONDEMNATION.  If the Premises or any portion thereof or the Industrial
Center are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"),
this Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs. If more than ten
percent of the floor area of the Premises, or more than twenty-five percent of
that portion of the Common Areas designated as parking for the Industrial
Center is taken by condemnation, Lessee may, at Lessee's option, to be
exercised in writing only within ten (10) days after Lessor shall have given
Lessee written notice of such taking (or in the absence of such notice, within
ten (10) days after the condemning authority shall have taken possession)
terminate this Lease as of the date the condemning authority takes such
possession. If Lessee does not terminate this Lease in accordance with the
foregoing, this Lease shall remain in full force and effect as to the portion
of the premises remaining, except that the rent shall be reduced in the
proportion that the floor area of the Premises taken bears to the total floor
area of the Premises. No reduction of rent shall occur if the only area taken
is that which does not have the Premises located thereon. Any award for the
taking of all or any part of the Premises under the power of eminent domain or
any payment made under threat of the exercise of such power shall be the
property of Lessor, whether such award shall be made as compensation for
diminution in value of the leasehold or for the taking of the fee, or as
severance damages; provided, however, that Lessee shall be entitled to any
award for loss of or damage to Lessee's trade fixtures and removable personal
property. In the event that this Lease is not terminated by reason of such
condemnation, Lessor shall to the extent of severance damages received by
Lessor in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Lessee has been
reimbursed therefor by the condemning authority. Lessee shall pay any amount in
excess of such severance damages required to complete such repair.

15.  BROKER'S FEE.

     (a)  Upon execution of this Lease by both parties, Lessor shall pay to 
Grubb & Ellis Company Licensed real estate broker(s), a fee as set forth in a
separate agreement between Lessor and said broker(s), for brokerage services
rendered by said broker(s) to Lessor in this transaction.

     (b)  Lessor agrees to pay said fee not only on behalf of Lessor but also
on behalf of any person, corporation, association, or other entity having an
ownership interest in said real property or any part thereof, when such fee is
due hereunder. Any transferee of Lessor's interests in this Lease, whether such
transfer is by agreement or by operation of law, shall be deemed to have
assumed Lessor's obligation under this paragraph 15. Said broker shall be a
third party beneficiary of the provisions of this paragraph 15.

16.  ESTOPPEL CERTIFICATE.
        
     (a)  Each party (as "responding party") shall at any time upon not less
than ten (10) days prior written notice from the other party ("requesting
party") execute, acknowledge and deliver to the requesting party a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults on the part of the requesting party, or specifying such
defaults if any are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Premises or of the business
of the requesting party.
        
     (b)  At the requesting party's option, the failure to deliver such
statement within such time shall be a material default of this Lease by the
party who is to respond, without any further notice to such party, or it shall
be conclusive upon such party that (i) this Lease is in full force and effect,
without modification except as may be represented by the requesting party,
(ii) there are no uncured defaults in the requesting party's performance, and 
(iii) if Lessor is the requesting party, not more than one month's rent has
been paid in advance.

     (c)  If Lessor desires to finance, refinance, or sell the Property, or any
part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statements of Lessee as may be reasonably
required by such lender or purchaser. Such statements shall include the past
three (3) years financial statements of Lessee. All such financial statements
shall be received by Lessor and such lender or purchaser in confidence and
shall be used only for the purposes herein set forth.

17.  LESSOR'S LIABILITY.  The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Industrial Center, and except as expressly
provided in paragraph 15, in the event of any transfer of such title or
interest. Lessor herein named (and in case of any subsequent transfers then the
grantor) shall be relieved from and after the date of such transfer of all
liability as respects Lessor's obligations thereafter to be performed, provided
that any funds in the hands of Lessor or the then grantor at the time of such
transfer, in which Lessee has an interest, shall be delivered to the grantee.
The obligations contained in this Lease to be performed by Lessor shall, subject
as aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

18.  SEVERABILITY.  The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way affect the validity of
any other provision hereof.

19.  INTEREST ON PAST-DUE OBLIGATIONS.  Except as expressly herein provided,
any amount due to Lessor not paid when due shall bear interest at the maximum
rate then allowable by law from the date due. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease; provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

20.  TIME OF ESSENCE.  Time is of the essence with respect to the obligations
to be performed under this Lease.

21.  ADDITIONAL RENT.  All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expenses and insurance and tax expenses payable shall be deemed to be rent.

22.  INCORPORATION OF PRIOR AGREEMENTS; AMENDMENTS.  This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
or contemporaneous agreement or understanding pertaining to any such matter
shall be effective. This lease may be modified in writing only, signed by the
parties in interest at the time of the modification. Except as otherwise
stated in this Lease, Lessee hereby acknowledges that neither the real estate
broker listed in paragraph 15 hereof nor any cooperating broker on this
transaction nor the Lessor or any employee or agents of any of said persons has
made any oral or written warranties or representations to Lessee relative to the
condition or use by Lessee of the Premises or the Property and Lessee
acknowledges that Lessee assumes all responsibility regarding the Occupational
Safety Health Act, the legal use and adaptability of the Premises and the
compliance thereof with all applicable laws and regulations in effect during
the term of this Lease except as otherwise specifically stated in this Lease.

23.  NOTICES.  Any notice required or permitted to be given hereunder shall be
in writing and may be given by personal delivery or by certified mail, and if
given personally or by mail, shall be deemed sufficiently given if addressed to
Lessee or to Lessor at the address noted below the signature of the respective
parties, as the case may be. Either party may by notice to the other specify a
different address for notice purposes except that upon Lessee's taking
possession of the Premises, the Premises shall constitute Lessee's address for
notice purposes. A copy of all notices required or permitted to be given to
Lessor hereunder shall be concurrently transmitted to such party or parties at
such addresses as Lessor may from time to time hereafter designate by notice
to Lessee.

24.  WAIVERS.  No waiver by Lessor or any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision. Lessor's consent to, or approval of, any act
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee. The acceptance of rent hereunder
by Lessor shall not be a waiver of any preceding breach by Lessee of any
provision hereof other than the failure of Lessee to pay the particular rent so
accepted, regardless of Lessor's knowledge of such preceding breach at the time
of acceptance of such rent.

25.  RECORDING.  Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26.  HOLDING OVER.  If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of
this Lease pertaining to the obligations of Lessee, but all Options, if any,
granted under the terms of this Lease shall be deemed terminated and be of no
further effect during said month to month tenancy.

27.  CUMULATIVE REMEDIES.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies
at law or in equity.

28.  COVENANTS AND CONDITIONS.  Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29.  BINDING EFFECT; CHOICE OF LAW.  Subject to any provisions hereof
restricting assignment or subletting by Lessee and subject to the provisions of
paragraph 17, this Lease shall bind the parties, their personal 
representatives, successors and assigns. This Lease shall be governed by the
laws of the State where the Industrial Center is located and any litigation
concerning this Lease between the parties hereto shall be initiated in the
county in which the Industrial Center is located.

30.  SUBORDINATION.

     (a)  This Lease, and any Option granted hereby, at Lessor's option, shall
be subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Industrial Center
and to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee or ground lessor shall elect to have this Lease and any
Options granted hereby prior to the lien of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Options shall be deemed prior to such mortgage, deed of trust or ground
lease, whether this Lease or such Options are dated prior or subsequent to the
date of said mortgage, deed of trust or ground lease or the date of recording 
thereof.

     (b)  Lessee agrees to execute any documents required to effectuate an
attornment, a subordination or to make this Lease or any Option granted herein
prior to the lien of any mortgage, deed of trust or ground lease, as the case
may be. Lessee's failure to execute such documents within ten (10) days after
written demand shall constitute a material default by Lessee hereunder without
further notice to Lessee or, at Lessor's option, Lessor shall execute such
documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee does hereby
make, constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact
and in Lessee's name, place and stead, to execute such documents in accordance
with this paragraph 30(b).

31.  ATTORNEY'S FEES.  If either party or the broker(s) named herein bring an
action to enforce the terms hereof or declare rights hereunder, the prevailing
party in any such action, on trial or appeal, shall be entitled to his
reasonable attorney's fees to be paid by the losing party as fixed by the
court. The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

32.  LESSOR'S ACCESS.  Lessor and Lessor's agents shall have the right to enter
the Premises at reasonable times for the purpose of inspecting the same,
showing the same to prospective purchasers, lenders, or lessees, and making
such alterations, repairs, improvements or additions to the Premises or to the
building of which they are part as Lessor may deem necessary or desirable.
Lessor may at any time place on or about the Premises or the Building any
ordinary "For Sale" signs and Lessor may at any time during the last 120 days
of the term hereof place on or about the Premises any ordinary "For Lease"
signs. All activities of Lessor pursuant to this paragraph shall be without
abatement of rent, nor shall Lessor have any liability to Lessee for the same.
See Addendum Paragraph 16.

33.  AUCTIONS.  Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent. Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated to
exercise any standard of reasonableness in determining whether to grant such 
consent.

34.  SIGNS.  Lessee shall not place any sign upon the Premises or the
Industrial Center without Lessor's prior written consent. Under no
circumstances shall Lessee place a sign on any roof of the Industrial Center.
See Addendum Paragraph 17.

35.  MERGER.  The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to
Lessor of any or all of such subtenancies.

36.  CONSENTS.  Except for paragraph 33 hereof, wherever in this Lease the
consent of one party is required to an act of the other party such consent
shall not be unreasonably withheld or delayed.

37.  GUARANTOR.  In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

38.  QUIET POSSESSION.  Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease. The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the 
Property.

39.  OPTIONS.  See Addendum Paragraph 3.

     39.1  DEFINITION.  As used in this paragraph the word "Option" has the
following meaning: (1) the right or option to extend the term of this Lease or
to renew this Lease or to extend or renew any lease that Lessee has on other
property of Lessor; (2) the option or right of first refusal to lease the
Premises or the right of first offer to lease the Premises or the right of
first refusal to lease other space within the Industrial Center or other
property of Lessor or the right of first offer to lease other space within the
Industrial Center or other property of Lessor; (3) the right or option to
purchase the Premises or the Industrial Center, or the right of first refusal
to purchase the Premises or the Industrial Center, or the right of first offer
to purchase the Premises or the Industrial Center, or the right or option to
purchase other property of Lessor, or the right of first refusal to purchase
other property of Lessor or the right of first offer to purchase other property
of Lessor.

     39.2  OPTIONS.  The Options, if any, herein granted to Lessee are not
assignable separate and apart from this Lease, nor may any Option be separated
from this Lease in any manner, either by reservation or otherwise.

     39.3  MULTIPLE OPTIONS.  In the event that Lessee has any multiple options
to extend or renew this Lease a later option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised.

     39.4  EFFECT OF DEFAULT ON OPTIONS.

           (a)  Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i)
during the time commencing from the date Lessor gives to Lessee a notice of
default pursuant to paragraph 13.1(b) or 13.1(c) and continuing until the
noncompliance alleged in said notice of default is cured, or (ii) during the
period of time commencing on the date after a monetary obligation to Lessor is
due from Lessee and unpaid (without any necessity for notice thereof to Lessee)
and continuing until the obligation is paid, or (iii) at any time after an
event of default described in paragraphs 13.1(a), 13.1(d), or 13.1(e) (without
any necessity of Lessor to give notice of such default to Lessee), nor (iv) in
the event that Lessor has given to Lessee three or more notices of default
under paragraph 13.1(b), or paragraph 13.1(c), whether or not the defaults are
cured, during the 12 month period of time immediately prior to the time that
Lessee attempts to exercise the subject Option.

           (b)  The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Lessee's inability to exercise
an Option because of the provisions of paragraph 39.4(a).

           (c)  All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due
and timely exercise of the Option. If, after such exercise and during the term
of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of
Lessee for a period of thirty (30) days after such obligation becomes due
(without any necessity of Lessor to give notice thereof to Lessee), or (ii)
Lessee fails to commence to cure a default specified in paragraph 13.1(c)
within thirty (30) days after the date that Lessor gives notice to Lessee of
such default and/or Lessee fails thereafter to diligently prosecute said cure
to completion, or (iii) Lessee commits a default described in paragraph
13.1(a), 13.1(d) or 13.1(e) (without any necessity of Lessor to give notice of
such default to Lessee), or (iv) Lessor gives to Lessee three or more notices
of default under paragraph 13.1(b), or paragraph 13.1(c), whether or not the
defaults are cured.

40.  SECURITY MEASURES.  Lessee hereby acknowledges that Lessor shall have no
obligation whatsoever to provide guard service or other security measures for
the benefit of the Premises or the Industrial Center. Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents and invitees from acts of third
parties. Nothing herein contained shall prevent Lessor, at Lessor's sole
option, from providing security protection for the Industrial Center or any
part thereof, in which event the cost thereof shall be included within the
definition of Operating Expenses, as set forth in paragraph 4.2(b).

41.  EASEMENTS.  Lessor reserves to itself the right, from time to time, to
grant such easements, rights and dedications that Lessor deems necessary or
desirable, and to cause the recordation of Parcel Maps and restrictions, so
long as such easements, rights, dedications, Maps and restrictions do not
unreasonably interfere with the use of the Premises by Lessee. Lessee shall
sign any of the aforementioned documents upon request of Lessor and failure to
do so shall constitute a material default of this Lease by Lessee without the
need for further notice to Lessee.

42.  PERFORMANCE UNDER PROTEST.  If at any time a dispute shall arise as to any
amount or sum of money to be paid by one party to the other under the
provisions hereof, the party against whom the obligation to pay the money is
asserted shall have the right to make payment "under protest" and such payment
shall not be regarded as a voluntary payment, and there shall survive the right
on the part of said party to institute suit for recovery of such sum. If it
shall be adjudged that there was no legal obligation on the part of said party
to pay such sum or any part thereof, said party shall be entitled to recover
such sum or so much thereof as it was not legally required to pay under the
provisions of this Lease.

                                                                Initials:  WRP

or partnership, Lessee shall, within thirty (30) days after execution of this
Lease, delivery to Lessor evidence of such authority satisfactory to Lessor.

typewritten or handwritten provisions, if any, shall be controlled by the

                                ADDENDUM TO LEASE

         1. Premises. The Industrial Center is located at 16825 Via del Campo
Court, San Diego, California and is more particularly described on Exhibit A
attached hereto. The Premises includes the entire Building and is divided into
the "First Premises" and "Second Premises". The First Premises consists of the
entire Building, excluding therefrom the Second Premises. The approximately
34,000 rentable square foot portion of the Building contained within the First
Premises is shown crosshatched on Exhibit A-1 attached hereto, including
approximately 4,000 square feet of unimproved space (the "Unimproved Portion").
The Second Premises consists of approximately 17,956 rentable square feet of
unimproved space in the Building and is shown as not crosshatched on Exhibit A-1
attached hereto. Upon the commencement of this Lease, Lessee shall lease the
First Premises. Lessee shall have the option to lease the Second Premises and
include it in the Premises at any time by giving Lessor sixty (60) days' prior
irrevocable written notice (the "Option Notice"); provided, however, if Lessee
has not given the Option Notice to Lessor on or before April 1, 1995, (i) Lessee
shall pay Lessor $21,000 on or before June 1, 1995 to reimburse Lessor for a
portion of Lessor's lost revenues and other costs of holding the Second Premises
off the market and available for Lessee's rental, (ii) at any time after April
1, 1995 that Lessee has not given the Option Notice to Lessor, Lessor may
terminate Lessee's option and all other rights to lease the Second Premises by
written notice to Lessee given at any time; and (iii) in the event Lessor has
not given such written notice by May 31, 1996 and Lessee has not given the
Option Notice by May 31, 1996, Lessee's option and all other rights to lease the
Second Premises shall terminate. All references in this Lease to the "Premises"
shall mean and refer to only the First Premises unless and until the Second
Premises becomes leased by Lessee pursuant to this paragraph, and shall mean and
refer collectively to the First Premises and the Second Premises if and after
the Second Premises has become leased by Lessee. In the event Lessee's option to
lease the Second Premises terminates pursuant to clause (iii) above in this
paragraph, this Lease shall terminate on June 30, 1996 as to the approximately
4,000 square foot Unimproved Portion of the First Premises, and thereafter the
approximately 30,000 square foot remainder of the First Premises shall
constitute the Premises under this Lease. In the event this Lease terminates as
to the Unimproved Portion pursuant to the immediately preceding sentence, Lessee
shall surrender and vacate the Unimproved Portion on June 30, 1996 pursuant to
Paragraph 7.3, and all other provisions of this Lease applicable to a
termination of this Lease shall be applicable to such partial termination as to
the Unimproved Portion. Upon the termination of this Lease with respect to the
Unimproved Portion, the Base Rent for the First Premises, as indicated in the
table set forth in Section 5 below, shall be reduced as of the later of July 1,
1996 or the date upon which Lessee surrenders the Unimproved Portion to Lessor
pursuant to the provisions of this Lease, to $18,000 per month for the remainder
of 1996, subject to further escalation of Base Rent pursuant to the provisions
of Section 5 below.

         2. Parking. Lessee shall be entitled to three (3) vehicle parking
spaces per 1,000 square feet of the Premises pursuant to Paragraph 2.2 and the
other provisions of this Lease. Lessor shall not be responsible for any changes
in laws or any act by any third party that may restrict the actual or practical
utilization by Lessee of the vehicle parking spaces allocated to Lessee as set
forth above, nor shall any such changes in laws or any act by any third party
give rise to any right by Lessor to terminate this Lease, abate any rent
hereunder or otherwise receive any accommodation from Lessor.

         3. Options to Extend. Subject to the provisions of Paragraph 39 of this
Lease, Lessee shall have two (2) successive options to extend the term of this
Lease for a period of three (3) years each, by giving Lessor irrevocable written
notice of Lessee's
<PAGE>   10
election to extend on or before April 1, 1998 as to the first extension period,
and April 1, 2001 as to the second extension period.

         4. Early Occupancy. Lessee's right to occupy the First Premises (except
for the approximately 4,000 square feet of unimproved space) prior to the
January 1, 1994 commencement date of this Lease shall commence on the date
thirty (30) days after execution of this Lease by both Lessor and Lessee. Lessee
shall not be required to pay Base Rent or Lessee's Share of Operating Expenses
(except for Lessee's Share of utilities costs) for the period of occupancy prior
to the commencement date, but shall be required to fulfill all of Lessee's other
obligations under this Lease.

         5. Rent. Base Rent for the Premises shall be as
follows:

Notwithstanding the amounts set forth in the foregoing table, provided Lessee is
not in default under any of the provisions of this Lease, Base Rent shall be
abated for the months of January through March, 1994 and January through March,
1995.

         *Commencing on January 1, 1997 and on each January 1 thereafter
throughout the remaining initial term and the extension term(s) of this Lease
(each, a "Rental Adjustment Date"), Base Rent shall be increased as to each of
the First Premises and Second Premises, respectively, by the percentage
increase, if any, in the Consumer Price Index All Items -- All Urban Consumers,
Riverside-Long-Beach-Anaheim Average (Reference Base Year 1988 = 100), as
published by the United States Department of Labor, Bureau of Labor Statistics
or its successor (the "Index"), as follows: the Base Rent in effect immediately
prior to the applicable Rental Adjustment Date (the "Comparison Monthly Rent")
shall be increased by the percentage that the Index has increased from the Index
published most recently prior to the month in which the first payment of the
Comparison Monthly Rent commenced through the Index published most recently
prior to the month in which the applicable Rental Adjustment Date occurs;
provided, however, in no event shall the Comparison Monthly Rent ever be
increased on any particular Rental Adjustment Date by reason of the computations
set forth above by less than three percent (3%) or more than six percent (6%).
If the Index ceases to be published or is published less frequently or is
altered in any material respect, then the parties shall adopt a substitute index
or substitute procedure which

                                        2
<PAGE>   11
reasonably reflects and monitors changes in consumer prices. Lessor shall notify
Lessee of the new Base Rent as soon as practicable following Lessor's
determination thereof as set forth above in this paragraph. If Lessor has not
given such notice prior to the applicable Rental Adjustment Date, Lessee shall
pay Base Rent at the Comparison Monthly Rent rate until Lessor so notifies
Lessee of the new amount of Base Rent; provided that, after Lessor provides such
notice, Lessee shall immediately pay Lessor any additional amounts owed based
upon the new amount of Base Rent payable pursuant to this Lease.

         6. Lessee's Share of Operating Expenses. So long as the Premises
includes only the First Premises, Lessee's Share of Operating Expenses, as set
forth in Paragraph 4.2 of this Lease, shall be 100%; provided, however, that
Lessee's Share as to costs for insurance required pursuant to Paragraphs 8.2 and
8.3 of the Lease and as to Real Property Taxes described in Paragraph 10 of the
Lease shall be 88%; and provided further that Lessor shall be responsible for
$125 per month toward the payment of all other Operating Expenses as Lessor's
full share allocable to the Second Premises prior to Lessee's leasing thereof.
After Lessee expands into the Second Premises (i.e., such that the Premises then
includes the entire Building), Lessee's Share of Operating Expenses shall be
100% without exception. Operating Expenses also shall include an administrative
fee to Lessor in the amount of the lesser of $1,000 per month or five percent
(5%) of all Operating Expenses other than such administrative fee and any other
Operating Expense incurred by Lessor to a third party and as to which Lessor
pays such third parties a management or administrative fee. Notwithstanding the
foregoing, in the event Lessor actually occupies any portion of the Building not
included within the Premises from time to time, Lessor shall bear all increases
in Operating Expenses attributable to such use or occupancy by Lessor.
Notwithstanding the provisions of Paragraph 4.2 of this Lease or this Section,
in no event shall Lessee have any obligation to pay directly, or reimburse
Lessor for, all or any portion of the following (except if incurred as a result
of Lessee's breach of any provision of this Lease or the negligent or other
wrongful conduct of Lessee or its employees, agents, contractors or invitees):

            a. costs occasioned by the wrongful act, omission of applicable
      rules, regulations, statutes, ordinances, laws and building codes by
      Lessor or any occupant of the Industrial Center or their respective
      agents, employees or contractors (other than Lessee or its employees,
      agents, contractors or invitees);

            b. costs occasioned by fire, acts of God or other casualties, or by
      the exercise of the power of eminent domain, to the extent that Lessor is
      compensated therefor through the proceeds of insurance or condemnation
      awards;

            c. costs of a capital nature, including, but not limited to, capital
      improvements and equipment, all as determined in accordance with generally
      accepted accounting principles and sound management practices, except any
      cost of a capital nature that is made to comply with laws or governmental
      requirements (provided such improvement or equipment is not required to
      cure a breach of Lessor's representations or covenants under this Lease)
      or for the purpose of reducing Operating Expenses (and, as to the latter,
      with a reasonable belief by Lessor that such improvement or equipment will
      reduce Operating Expenses by more than the amount of such capital cost
      over the useful life of such improvement or equipment), the amount of such
      costs to be amortized on a straight-line basis over the useful life of the
      improvement or equipment in question as Lessor shall reasonably determine;

            d. costs for which Lessor is entitled to

                                       3
<PAGE>   12
      reimbursement from others;

            e. costs of correcting any construction defect in the Premises or
      the Industrial Center existing on the date of this Lease;

            f. costs of any renovation, improvement, painting or redecorating of
      any portion of the Industrial Center not made available for Lessee's Use;

            g. any costs or other disbursements incurred in connection with
      negotiations or disputes with any occupant of the Industrial Center (other
      than Lessee), and the costs arising from the violation by Lessor or any
      occupant of the Industrial Center (other than Lessee or its employees,
      agents, contractors or invitees) of the terms or conditions of any Lease
      or other agreement;

            h. depreciation, amortization or other expense reserves;

            i. interest, charges and fees incurred on debt, and payments on
      mortgages and rent under ground leases;

            j. increases in insurance premiums or costs caused by the activities
      of other occupants of the Industrial Center (other than Lessee or its
      employees, agents, contractors or invitees);

            k. any costs associated with hazardous or toxic materials, except to
      the extent caused by the storage, use or disposal of hazardous materials
      by Lessee or its employees, agents, contractors or invitees;

            l. any costs properly attributable to property owned or operated by
      Lessor outside of the physical boundaries of the Industrial Center;

            m. leasing commissions, attorneys' fees, costs and disbursements and
      other expenses incurred in connection with negotiations or disputes with
      tenants or other occupants or prospective tenants or other occupants of
      the Building; or

            n. any amount that would constitute a "double recovery" by Lessor
      (i.e., in excess of 100% of the costs incurred by Lessor, plus Lessor's
      administrative fee).

         7. Use. The Premises may be used and occupied for any lawful use in
compliance with all covenants, conditions and restrictions affecting the
Industrial Center, except that the Premises shall not be used for the
manufacturing, design, research, development or sale of aerospace products or
related uses.

         8. Hazardous Materials; As-Is Condition. Lessor represents and warrants
to Lessee that, to the actual knowledge of the officers of Lessor, upon the date
of this Lease (i) the Industrial Center is not contaminated by wastes or other
materials in a manner and in concentrations and formulations that are currently
generally recognized as being injurious to public health or safety, and (ii)
Lessor has not manufactured, stored or generated any such materials or wastes at
the Industrial Center, except in accordance with all applicable law and
commercially reasonable standards. In the event that it is determined that
Lessor's warranties set forth in this Section have been violated, then it shall
be the obligation of Lessor, after receipt of written notice from Lessee setting
forth with specificity the nature of the violation, to promptly rectify such
violation at Lessor's sole cost. Except for the responsibility of Lessor for the
condition of the Premises expressly assumed pursuant to Paragraphs 6.2 and 6.3
of this Lease and this Section 8, Lessee agrees that it is leasing

                                       4
<PAGE>   13
the Premises "AS IS AND WITH ALL FAULTS."

         9. Lessor's Maintenance Obligations. Notwithstanding the provisions of
Paragraph 7.1 of this Lease, in the event Lessee does not desire to wait for
Lessor to perform one or more of its obligations within the period of time
permitted under Paragraph 7.1 of this Lease, or in the event of an emergency,
Lessee shall have the right to perform Lessor's obligation(s) under Paragraph
7.1 at Lessee's expense, provided that (except in an emergency) Lessee informs
Lessor in writing of Lessee's intention to perform Lessor's obligation(s) and
Lessor does not inform Lessee within five (5) days after receipt of Lessee's
notice that Lessor will commence to perform such obligation(s) within ten (10)
days after Lessor's receipt of such notice from Lessee. At any time and from
time to time during the term of this Lease, Lessor shall have the right to turn
over to Lessee all or any portion of Lessor's obligations pursuant to Paragraph
7.1 of this Lease by giving written notice of such election to Lessee, upon
which notice Lessee shall be deemed to have assumed all of Lessor's obligations
as to which such election applies. In addition, at any time if and after the
Premises is expanded to include the Second Premises, Lessee shall have the right
to assume all (but not part) of Lessor's obligations under Paragraph 7.1 of this
Lease not previously turned over by Lessor to Lessee by giving irrevocable
written notice of such election to Lessor, provided that Lessee reasonably
satisfies Lessor that Lessee will fully satisfy the provisions of Paragraph 7.1.
If, at any time after Lessee has assumed Lessor's obligations under Paragraph
7.1 pursuant to this Section, Lessee fails to fulfill the obligations so
assumed, Lessor shall have the right to perform all or any portion of such
obligations on Lessee's behalf as permitted under Paragraph 7.2(b) with respect
to Lessee's obligations under Paragraph 7.2.

        10. Thermal Energy Storage System. Lessor and Lessee acknowledge that
there is installed in the Building a Thermal Energy Storage System ("TES
System"). Lessee acknowledges that Lessor's warranty as to the TES System set
forth in paragraph 6.3 of this Lease shall not constitute any guaranty or
warranty as to the energy output, specifications or quality of performance of
the TES System or its sufficiency to meet Lessee's needs. Lessor shall maintain
and repair the TES System throughout the term of this Lease, all costs of which
shall be considered Operating Expenses to be reimbursed by Lessee pursuant to
the Provisions of Paragraph 4.2 of this Lease and Section 6 above.

        11. Lessee's Improvements. Lessee agrees to make the interior
improvements to the Premises substantially in accordance with Exhibit B attached
hereto (the "Tenant Improvements"). Lessee agrees to diligently prosecute all
required governmental approvals for the Tenant Improvements. Lessee shall
deliver to Lessor complete plans and specifications for the Tenant Improvements
on or before March 1, 1994, which shall be subject to the approval of Lessor
pursuant to the provisions of paragraph 7.3 of this Lease, which approval by
Lessor shall not be unreasonably withheld. Lessor shall have fifteen (15) days
after receipt of such complete plans and specifications to approve or disapprove
them; provided, however, that such plans and specifications shall be deemed
approved unless Lessor gives notice of disapproval within such fifteen-day
period. If Lessor disapproves of any plans or specifications, Lessor shall give
reasons for such disapproval and Lessor and Lessee shall negotiate in good faith
to address Lessor's reasonable objections. All plans and specifications shall be
prepared by a duly licensed or registered architect or engineer, as the case may
be (except, however, any nonstructural conceptual space and interior design
plans may be prepared by a reputable space planner or interior designer). All
contractors employed by Lessee to make structural alterations shall be approved
by Lessor, which approval shall not be unreasonably withheld. Within thirty (30)
days after receipt by Lessee of all necessary governmental approvals for the
Tenant Improvements and Lessor's approval of

                                       5
<PAGE>   14
Lessee's plans and specifications, Lessee shall commence and diligently
prosecute the Tenant Improvements in accordance with the approved plans and
specifications and all governmental approvals and otherwise in accordance with
this Lease and applicable law. Lessee shall cause completion of the Tenant
Improvements to occur on or before the later of July 31, 1994 or within sixty
(60) days after commencement of on-site demolition or construction activities.
During the construction period, Lessee shall not block or otherwise interfere
with the use of any traffic or parking improvements or fire lanes, except as
specifically permitted by Lessor and the City of San Diego during the process of
obtaining approvals for the Tenant Improvements. In addition, Lessee shall
repair and restore all damage to the Common Areas or other facilities located on
or about the Industrial Center caused in accordance with Lessee's construction
activities, including, but not limited to, landscaping, lighting and paving.
Lessee shall not allow work to cease during the construction period for longer
than five (5) business days at a time or twenty (20) business days in the
aggregate. Notwithstanding the foregoing, in the event Lessee is unable to
commence or complete construction of the Tenant Improvements in accordance with
the foregoing terms due to events beyond Lessee's control, the time period for
commencing or completing the Tenant Improvements, as the case may be, shall be
extended by a period of time equal to the duration of such events. Events beyond
Lessee's control include, but shall not be limited to, acts of God, civil
commotion, fire, flood or other casualty, shortages of labor or materials and
governmental prohibition or moratorium.

        12. Removal of Equipment and Improvements. Notwithstanding the
provisions of Paragraph 7.3(a) of this Lease, Lessor shall not have the right to
require Lessee to remove, and Lessee shall not have the right to remove, (i) any
of the Tenant Improvements described in Section 11 above, and (ii) as to any
other alteration, improvement, addition or Utility Installation Lessee is
required to obtain, actually obtains Lessor's approval unless, at the time that
Lessor gives such approval, Lessor notifies Lessee in writing that Lessor may
require remove of such alteration, improvement, addition or Utility Installation
upon expiration of this Lease. For the purposes of Paragraph 7.3 of this Lease,
Lessor and Lessee agree that the Novatech materials handling system to be
installed by Lessee shall be equipment that Lessee may remove upon expiration of
this Lease (subject to Lessee's repair obligations and other applicable
provisions of this Lease), and that all improvements, systems, equipment,
machinery, materials and finishes pertaining to the "clean rooms" to be
constructed by Lessee as part of the Tenant Improvements shall constitute
improvements that may not be removed by Lessee at any time.

        13. Indemnity. Notwithstanding anything to the contrary in this Lease,
Lessee shall neither release nor indemnify Lessor from any damages, liabilities,
judgements, actions, claims, attorneys' fees, consultants' fees, payments, costs
or expenses arising from (i) the negligence or willful misconduct of Lessor or
its employees, agents, contractors or invitees, (ii) Lessor's violation of laws
or (iii) any breach by Lessor of its obligations, representations or warranties
under this Lease.

        14. Damage or Destruction. Notwithstanding the provisions of Paragraph
9.2 of this Lease, in the event the Premises or the Building is damaged or
destroyed at any time prior to December 31, 1997 to the extent that the cost of
repair is equal to or greater than fifty percent (50%) of the then replacement
costs of the Premises or the Building, respectively, but less than seventy
percent (70%) of such respective replacement cost, such damage or destruction
shall be considered to be "Premises Partial Damage" or "Premises Building
Partial Damage", as the case may be, provided that, within thirty (30) days
after the occurrence of such damage or destruction, Lessee shall give Lessor
unconditional and

                                       6
<PAGE>   15
irrevocable written notice to exercise immediately both options to extend this
Lease as set forth in Section 3 above (to the extent not already exercised), and
provided further that the Premises then include the Second Premises or, if it
does not and such damage or destruction has occurred prior to March 1, 1995,
Lessee shall give Lessor the Option Notice pursuant to Section 1 above within
thirty (30) days after the occurrence of such damage or destruction.
Notwithstanding the provisions of Paragraph 9.2 of this Lease, in the event the
Premises or the Building is damaged or destroyed at any time after December 31,
1997 and before December 31, 1999 to the extent that the cost of repair is equal
to or greater than fifty percent (50%) of the then replacement costs of the
Premises or the Building, respectively, but less than sixty percent (60%) of
such respective replacement cost, such damage or destruction shall be considered
to be "Premises Partial Damage" or "Premises Building Partial Damage", as the
case may be, provided that, within thirty (30) days after the occurrence of such
damage or destruction, Lessee shall give Lessor unconditional and irrevocable
written notice to exercise immediately both options to extend this Lease as set
forth in Section 3 above (to the extent not already exercised), and provided
further that the Premises then includes the Second Premises.

        15. Assignment and Subleasing. Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet or otherwise transfer or
encumber all or any part of Lessee's interest in this Lease or in the Premises
to any company domiciled, or engaged in business primarily, outside of the
United States of America, or to any party whom Lessee has reason to believe will
violate or seek to violate the use restrictions set forth in Section 7 above or
any other applicable provision of this Lease. Any attempt at any such transfer
by Lessee shall be void and shall constitute an incurable default under this
Lease by Lessee.

        16. Lessor's Access. All entries into the Premises by Lessor shall be
made during normal business hours upon at least twenty-four (24) hours' prior
notice to Lessee, except in the case of an emergency in which case no prior
notice shall be required.

        17. Signage. Lessee has received and reviewed a copy of the Declaration
of Covenants, Conditions and Restrictions, together with sign criteria for the
Industrial Center adopted in connection therewith, and acknowledges that they
contain restrictions regarding the placement of signs on or about the Property.
Lessor's approval of all signage pursuant to paragraph 34 of this Lease shall
extend to both the design and location of all signage, which approval shall not
be unreasonably withheld. Lessee shall be responsible for the entire cost of all
installation, maintenance and repair of its signage. Lessee shall move all of
its signage upon termination of this Lease and shall return the Premises to
their condition prior to the placement or erection of all such signage. Subject
to the foregoing, Lessee shall have the sole right to use of building and
monument signage at the Industrial Center.

        18. Lessee's Right of First Offer/Refusal.

            (a) Initial Negotiation. At least thirty (30) days before Lessor
undertakes any effort to market, sell, exchange or otherwise voluntarily
transfer (any such transaction described above shall be referred to as a
"Transfer") all or any portion of the Industrial Center, Lessor shall deliver to
Lessee a written offer setting forth the proposed price and other terms on which
Lessor is willing to sell the entire Industrial Center to Lessee. Lessee shall
have thirty (30) days following its receipt of Lessor's offer (the "Negotiating
Period") in which to negotiate with Lessor to purchase the entire Industrial
Center and to enter into a binding contract with Lessor for the purchase and
sale of the entire Industrial Center. At the end of the Negotiating

                                       7
<PAGE>   16
Period, and in the event Lessor and Lessee do not enter into a binding contract
for such purchase and sale, Lessor shall prepare a document setting forth all of
the final terms offered by Lessor and rejected by Lessee (the "Final Rejected
Offer"), which both Lessor and Lessee shall acknowledge in writing. The Final
Rejected Offer shall serve as the basis against which it shall be determined
whether the terms of any subsequent proposed offer or agreement regarding the
Transfer of the Industrial Center are materially less favorable to the Lessor.

            (b) Transfers During Following Year. In the event Lessor and Lessee
do not enter into a binding contract for the purchase and sale of the entire
Industrial Center during the Negotiating Period, Lessor may enter into an
agreement to make a Transfer of all or any portion of the Industrial Center
during the 12-month period immediately following the Negotiating Period for a
total consideration of not less than ninety-five percent (95%) of that specified
in the Final Rejected Offer and with other material financial terms not
materially less favorable to the Lessor than those contained in the Final
Rejected Offer; provided that any such agreement may contain financing terms
materially different from those of the Final Rejected Offer, provided the
purchase price is paid over a period of not more than ten (10) years and the
interest rate to Lessor is at least equal to the "prime" or "reference" rate of
major banks. Other terms, such as a longer escrow period, more or different
contingencies in favor of the proposed buyer, guaranties or indemnities offered
by Lessor and the inclusion of other transactions in the purchase and sale
transaction, shall not be considered financial terms for the purposes of this
paragraph. Any Transfer permitted pursuant to the foregoing provisions of this
paragraph is referred to as a "Permitted Transaction". If Lessor does not enter
into a binding agreement for a Permitted Transaction during the 12-month period
following the expiration of the Negotiating Period as permitted pursuant to this
paragraph, and if Lessor thereafter wishes to undertake further efforts to make
a Transfer of all or any portion of the Industrial Center, Lessor first may
repeat the procedures set forth in Section 18(a) above.

            (c) Right of First Refusal. No interest in all or any portion of the
Industrial Center, except pursuant to a Permitted Transaction under Section
18(b) above, shall be conveyed to any person or entity, either voluntarily or
involuntarily, without Lessor's first offering such interest (the "Offered
Interest") to Lessee on the same terms and conditions proposed between Lessor
and the third party. Lessor shall deliver to Lessee a written offer specifying
the materials terms of the proposed conveyance of the offered interest and
naming the proposed transferee (the "Offer Notice"). A letter attaching the
written offer or proposed agreement between Lessor and the proposed transferee
shall be a sufficient Offer Notice. Lessor's delivery of an Offer Notice shall
constitute a representation by Lessor that the proposed conveyance referred to
in the Offer Notice is a bonafide transaction negotiated at arms' length with an
independent transferee who is unaffiliated with Lessor. The offer made to Lessee
by delivery of the Offer Notice shall be irrevocable for a period of five (5)
days after receipt by Lessee, during which the offer may be accepted or rejected
by Lessee. In the event Lessee accepts the offer within such five (5) day
period, Lessor and Lessee shall consummate the transfer of the Offered Interest
in accordance with the terms set forth in the Offer Notice. In the event, within
five (5) days after Lessee's receipt of the Offer Notice, Lessee does not accept
the offer unconditionally and irrevocably in writing on the exact terms and
conditions set forth in the Offer Notice, Lessee shall be deemed to have
rejected the offer and waived its right of first refusal as to the proposed
Transfer evidenced by the Offer Notice (including any changes thereto other than
changes to material financial terms that are materially less favorable to
Lessor). To the extent the following are consistent with, or not addressed by,
the terms and conditions specified in the Offer Notice: (i) Lessee shall have
thirty (30)

                                       8
<PAGE>   17
days after its acceptance of the offer in which to arrange financing for its
acquisition of the Offered Interest, (ii) the transfer of the Offered Interest
shall take place through an escrow with a title insurance company reasonably
acceptable to Lessor and Lessee, (iii) the closing of the transfer of the
Offered Interest shall occur within sixty (60) days after Lessee's receipt of
the Offer Notice, (iv) if the Offered Interest is a fee interest in the
Industrial Center, the transfer shall be made by grant deed, and (v) costs and
expenses in connection with the transfer of the Offered Interest to Lessee shall
be allocated between Lessor and Lessee as is customary in San Diego County.
Notwithstanding any provision of this paragraph to the contrary, Lessee's right
of first refusal shall not apply to any conveyance or hypothecation of all of
any portion of the Industrial Center in connection with Lessor's obtaining a
bonafide loan, or any conveyance of the Industrial Center by private sale
pursuant to the provisions of, upon foreclosure of, or by deed in lieu of
foreclosure with respect to, any deed of trust or security instrument given to
secure any such loan; provided, however, that Lessee shall be given notice of,
and the right to cure, any default under any deed of trust or other security
instrument. Notwithstanding any provision of this paragraph, Lessor shall at all
times have the free right to make any Transfer to any entity controlling,
controlled by or under common control with Lessor, or any person or entity that
may succeed to the interests of Lessor by merger or consolidation or by purchase
of all or substantially all of the assets of Lessor. For the purposes of this
paragraph, a person or entity shall be deemed to control every entity in which
he or it owns a majority interest or holds majority voting power, or both.
Lessee's right of first refusal granted pursuant to this paragraph shall
terminate upon the expiration or earlier termination of this Lease.

         IN WITNESS WHEREOF, Lessor and Lessee have executed this Addendum as a
part of the Lease to which this Addendum is attached, effective as of the date
of such Lease.

this Agreement, and USMI commitments to process products as set forth in this
Agreement, USMI agrees to purchase non-sterile assembled syringe products from
NPA in annual volumes no less than the "Minimum Volume Commitments", specified
on Schedule B attached hereto.

2.       SERVICES

Specifications listing and specifying in detail each of USMI products (the
"PRODUCTS") to be assembled by NPA, are attached hereto as Schedule C or are

"Manuals"), which are incorporated herein by reference. NPA will assemble,

NPA will render such services at the facility or facilities set forth on
Schedule B, or at such other facilities as USMI and NPA may hereafter agree. NPA

3.       FORECASTS

For NPA's planning purposes, and to insure timely processing of USMI's Products
in accordance with this Agreement, USMI agrees to provide, at the time this
Agreement is executed, and on no less than a quarterly basis thereafter
throughout the term of this Agreement, twelve month forecasts of its monthly
volume requirements with a three month firm requirement. At USMI's discretion
the product may be any size syringe manufactured by USMI.

4.       SCHEDULING AND DELIVERY

         (a) PURCHASE ORDERS. USMI shall provide purchase order(s) to NPA in
advance of USMI requested delivery dates, which purchase order(s) shall include
delivery instructions for each of the PRODUCTS to be processed. Each order,
including USMI requested delivery dates specified therein, is subject to
acceptance by NPA.

         (b) TIME OF DELIVERY. NPA shall be obligated to accept all of USMI

shipping containers to be provided by USMI. The PRODUCTS will be bagged and
labeled with USMI's part number, lot number, quantity and placed in the
containers in such a way as to protect the PRODUCTS from damage during
reasonable handling and shipment. Each container shall be labeled with USMI's
part number, lot number and quantity to match the PRODUCTS labeling. The
exterior of each container shall be labeled "NON-STERILE PRODUCT AWAITING
FURTHER PROCESSING". Each shipment of PRODUCTS from NPA shall be accompanied by
shipping papers, including but not limited to certification of materials,
manufacturing process, lot history records, all inspection data and
non-conforming material reports. Upon receipt of a shipment, USMI will complete
a Receiving Report on the shipment. If there is any discrepancy between the USMI
Receiving Report and the NPA shipping papers, USMI will promptly notify NPA of
the discrepancies. NPA shall be responsible for conducting a reconciliation to
correct any discrepancies and to locate any lost PRODUCTS, provided traceability
is maintained. USMI and NPA shall agree on a case by case basis on necessary
timeframes to remedy any such discrepancies. NPA will notify USMI of the results
of this reconciliation verbally and in writing in order to adjust USMI and/or
NPA records. USMI will be bound to payment for only the quantity of PRODUCTS
verified as received in the USMI Receiving Report. In the event of such
discrepancy, USMI shall not release any portion of the received product for
shipment until such discrepancy is resolved.

pending, or completed action or proceeding relating to any claim for which
either of the parties would be found ultimately liable as a matter of and on
account of which the other party has been made a party defendant pursuant to the
relationship between the parties under this contract. It is understood by the
parties that this paragraph does not create new claims of liabilities in either
of the parties, but is intended exclusively to (a) guarantee that the legal
liability that may arise for either of the parties on account of that party's
conduct under this contract is ultimately borne by that party, regardless of
which of the two is subjected to suit and (b) encourage either party to take
reasonable steps to cure or mitigate any liability that may arise without, by
virtue of that act alone, if taken reasonably, creating new liabilities or a
shift in liabilities that otherwise would lie.

each party and its successors and assigns.

         (d) SEVERABILITY. If any provision of this Agreement shall be held to

accomplish the net economic effect of such unenforceable or invalid provision
within the limits of applicable law.

         (e) ENTIRE AGREEMENT. This Agreement, together with the Schedule(s)

3. WCMA LOANS

(a) Activation Date. Provided that: (i) the Commitment Expiration Date shall not
then have occurred, and (ii) Customer shall have subscribed to the WCMA Program
and its subscription to the WCMA Program shall then be in effect, the Activation
Date shall occur on or promptly after the date following the acceptance of

                                      -2-
<PAGE>   3
this Loan Agreement by MLBFS at its office in Chicago, Illinois, upon which each
of the General Funding Conditions shall have been met or satisfied to the
reasonable satisfaction of MLBFS. No activation by MLBFS of the WCMA Line of
Credit for a nominal amount shall be deemed evidence of the satisfaction of any
of the conditions herein set forth, or a waiver of any of the terms or
conditions hereof.

(b) WCMA LOANS. Subject to the terms and conditions hereof, during the period
from and after the Activation Date to the Maturity Date: (i) MLBFS will make
WCMA Loans to Customer in such amounts as Customer may from time to time request
in accordance with the terms hereof, up to an aggregate outstanding amount not
to exceed the Maximum WCMA Line of Credit, and (ii) Customer may repay any WCMA
Loans in whole or in part at any time without premium or penalty, and request a
re-borrowing of amounts repaid on a revolving basis. Customer may request WCMA
Loans by use of WCMA Checks, FTS, Visa(R) charges, wire transfers, or such other
means of access to the WCMA Line of Credit as may be permitted by MLBFS from
time to time; it being understood that so long as the WCMA Line of Credit shall
be in effect, any charge or debit to the WCMA Account which but for the WCMA
Line of Credit would under the terms of the WCMA Agreement result in an
overdraft, shall be deemed a request by Customer for a WCMA Loan.

(c) CONDITIONS OF WCMA LOANS. Notwithstanding the foregoing, MLBFS shall not be
obligated to make any WCMA Loan, and may without notice refuse to honor any such
request by Customer, if at the time of receipt by MLBFS of Customer's request:
(i) the making of such WCMA Loan would cause the Maximum WCMA Line of Credit to
be exceeded; or (ii) the Maturity Date shall have occurred, or the WCMA Line of
Credit shall have otherwise been terminated in accordance with the terms hereof;
or (iii) Customer's subscription to the WCMA Program shall have been terminated;
or (iv) an event shall have occurred and is continuing which shall have caused
any of the General Funding Conditions to not then be met or satisfied to the
reasonable satisfaction of MLBFS. The making by MLBFS of any WCMA Loan at a time
when any one or more of said conditions shall not have been met shall not in any
event be construed as a waiver of said condition or conditions or of any Event
of Default, and shall not prevent MLBFS at any time thereafter while any
condition shall not have been met from refusing to honor any request by Customer
for a WCMA Loan.

(d) FORCE MAJEURE. MLBFS shall not be responsible, and shall have no liability
to Customer or any other party, for any delay or failure of MLBFS to honor any
request of Customer for a WCMA Loan or any other act or omission of MLBFS,
MLPF&S or any of their affiliates due to or resulting from any system failure,
error or delay in posting or other clerical error, loss of power, fire, Act of
God or other cause beyond the reasonable control of MLBFS, MLPF&S or any of
their affiliates unless directly arising out of the willful wrongful act or
active gross negligence of MLBFS. In no event shall MLBFS be liable to Customer
or any other party for any incidental or consequential damages arising from any
act or omission by MLBFS, MLPF&S or any of their affiliates in connection with
the WCMA Line of Credit of this Loan Agreement.

(e) INTEREST. The WCMA Loan Balance shall bear interest at the Interest Rate
Interest shall be computed for the actual number of days elapsed on the basis of
a year consisting of 360 days Notwithstanding any provision to the contrary in
this Agreement or any of the Additional Agreements, no provision of this
Agreement or any of the Additional Agreements shall require the payment or
permit the collection of any amount in excess of the maximum amount of interest
permitted to be changed by law ("Excess Interest"). If any Excess Interest is
provided for, or is adjudicated as being provided for, in this Agreement or any
of the Additional Agreements, then (a) Customer shall not be obligated to pay
any Excess Interest; and (b) any Excess Interest that MLBFS may have received
hereunder or under any of the Additional Agreements shall, at the option if
MLBFS, be: (i) applied as a credit against the then unpaid balance of the WCMA
Line of Credit, (ii) refunded to the payer thereof, or (iii) any combination of
the foregoing. Except as otherwise provided herein, accrued and unpaid interest
on the WCMA Loan Balance shall be payable monthly on the last Business Day of
each calendar month, commencing with the last Business Day of the calendar month
in which the Activation Dale shall occur. Customer hereby irrevocably authorizes
and directs MLPF&S to pay MLBFS such accrued interest from any available free
credit balances in the WCMA Account, and if such available free credit balances
are insufficient to satisfy any interest payment due, to liquidate any
investments in the Money Accounts (other than any investments constituting any
Minimum Money Accounts Balance under the WCMA Directed Reserve program) in an
amount up to the balance of such accrued interest, and pay to MLBFS the
available proceeds on account thereof. If available free credit balances in the
WCMA Account and available proceeds of the Money Accounts are insufficient to
pay the entire balance of accrued interest, and Customer




                                      -3-

<PAGE>   4
otherwise fails to make such payment when due, MLBFS may, in its sole
discretion, make a WCMA Loan in an amount equal to the balance of such accrued
interest and pay the proceeds of such WCMA Loan to itself on account of such
interest. The amount of any such WCMA Loan will be added to the WCMA Loan
Balance. If MLBFS declines to extend a WCMA Loan to Customer under these
circumstances, Customer hereby authorizes and directs MLPF&S to make all such
interest payments to MLBFS from any Minimum Money Accounts Balance. If there is
no Minimum Money Accounts Balance, or it is insufficient to pay all such
interest, MLBFS will invoice Customer for payment of the balance of the accrued
interest, and Customer shall pay such interest as directed by MLBFS within 5
Business Days or receipt of such invoice.

(f)  PAYMENTS.  All payments required or permitted to be made pursuant to this
Loan Agreement shall be made in lawful money of the United States. Unless
otherwise directed by MLBFS, payments on account of the WCMA Loan Balance may
be made by the delivery of checks (other than WCMA Checks), or by means of FTS
or wire transfer of funds (other than funds from the WCMA Line of Credit) to
MLPF&S for credit to Customer's WCMA Account. Notwithstanding anything in the
WCMA Agreement to the contrary, Customer hereby irrevocably authorizes and
directs MLPF&S to apply available free credit balances in the WCMA Account to
the repayment of the WCMA Loan Balance prior to application for any other
purpose. Payments to MLBFS from funds in the WCMA Account shall be deemed to be
made by Customer upon the same basis and schedule as funds are made available
for investment in the Money Accounts in accordance with the terms of the WCMA
Agreement. All funds received by MLBFS from MLPF&S pursuant to the aforesaid 
authorization shall be applied by MLBFS  to repayment of the WCMA Loan Balance.
The acceptance by or on behalf of MLBFS of a check or other payment for a
lesser amount than shall be due from Customer, regardless of any endorsement or
statement thereon or transmitted therewith, shall not be deemed an accord and
satisfaction or anything other than a payment on account, and MLBFS or anyone
acting on behalf of MLBFS may accept such check or other payment without
prejudice to the rights of MLBFS to recover the balance actually due or to
pursue any other remedy under this Loan Agreement or applicable law for such
balance. All checks accepted by or on behalf of MLBFS in connection with the
WCMA Line of Credit are subject to final collection.

(g)  EXCEEDING THE MAXIMUM WCMA LINE OF CREDIT.  In the event that the WCMA
Loan Balance shall at any time exceed the Maximum WCMA Line of Credit, Customer
shall within 1 Business Day of the first to occur of (i) any request or demand
of MLBFS, or (ii) receipt by Customer of a statement from MLPF&S showing a WCMA
Loan Balance in excess of the Maximum WCMA Line of Credit, deposit sufficient
funds into the WCMA Account to reduce the WCMA Loan Balance below the Maximum
WCMA Line of Credit.

(h)  LINE FEE; EXTENSIONS.  (i) In consideration of the extension of the WCMA
Line of Credit by MLBFS to Customer during the period from the Activation Date
to the Maturity Date, Customer has paid or shall pay the Line Fee to MLBFS. If
such fee has not heretofore been paid by Customer, Customer hereby authorizes
MLBFS, at its option, to either cause said fee to be paid with a WCMA Loan
which is added to the WCMA Loan Balance, or invoice Customer for said fee (in
which event Customer shall pay said fee within 5 Business Days after receipt of
such invoice). No delay in the Activation Date, howsoever caused shall entitle
Customer to any rebate or reduction in the Line Fee or extension of the
Maturity Date.

(ii) In the event MLBFS and Customer, in their respective sole discretion,
agree to renew the WCMA Line of Credit beyond the current Maturity Date,
Customer agrees to pay a renewal Line Fee or Line Fees (if the Maturity Date is
extended for more than one 12-month period), in the amount per 12-month period
or other applicable period then set forth in the writing signed by MLBFS which
extends the Maturity Date; it being understood that any request by Customer for
a WCMA Loan or failure of Customer to pay any WCMA Loan Balance outstanding on
the immediately prior Maturity Date, after the receipt by Customer of a writing
signed by MLBFS extending the Maturity Date, shall be deemed a consent by
Customer to both the renewal Line Fees and the new Maturity Date. If no renewal
Line Fees are set forth in the writing signed by MLBFS extending the Maturity
Date, the renewal Line Fee for each 12-month period shall be deemed to be the
same as the immediately preceding periodic Line Fee. Each such renewal Line
Fee, at the option of MLBFS, either be paid with a WCMA Loan which is added to
the WCMA Loan Balance or invoiced to Customer, as aforesaid, on or at any time
after the first Business Day of the first month of the 12-month period for
which such fee is due.

                                      -4-
<PAGE>   5
(i)  STATEMENTS.  MLPF&S will include in each  monthly statement it issues
under the WCMA Program information with respect to WCMA Loans and the WCMA Loan
Balance. Any questions that Customer may have with respect to such information
should be directed to MLBFS; and any questions with respect to any other matter
in such statements or about or affecting the WCMA Program should be directed 
to MLPF&S.

(j)  USE OF LOAN PROCEEDS; SECURITIES TRANSACTIONS.  The proceeds of each WCMA
Loan shall be used by customer solely for working capital in the ordinary
course of is business, or, with the prior written consent of MLBFS, for other
lawful business purposes of Customer not prohibited hereby. Customer agrees
that under no circumstances will funds borrowed from MLBFS through the WCMA
line of credit be used: (i) for personal, family or household purposes of any
person whatsoever, (ii) to purchase, carry or trade in securities, including
shares of the money accounts, or (iii) to repay debt incurred to purchase,
carry or trade in securities; nor will any such funds be remitted, directly or
indirectly, to MLPF&S or any other broker or dealer in securities, by WCMA
check, check, FTC, wire transfer, or otherwise.

                          MEMO OF UNDERSTANDING (MOU)
                   FIRST CLAIM AND WARRANT PURCHASE AGREEMENT

        This First Claim and Warrant Purchase Agreement (the "Agreement") is
made and entered into as of the 7th day of August, 1996 by and between U.S.
Medical Instruments, Inc., a California corporation (the "Company") and Robert

        A. Robert Siegel is a shareholder of the Company.

        B. Robert Siegel has agreed to pledge certain assets to help the Company
secure a line of credit of up to $5,000,000, and in consideration therefore, the
Company has agreed to grant a warrant for the exercise of 223,000 shares of
Common Stock of the Company to Mr. Siegel.

        In consideration of the mutual promises contained herein, the parties
hereto agree as follows:

        1. SECURED FIRST CLAIM. The parties hereby agree that Siegel shall
pledge certain assets as collateral as consideration to help the Company secure
a line of credit of up to $5,000,000. Immediately after the execution of the
Agreement the Company shall issue a Secured First Claim pursuant to the terms in
the form attached as Exhibit A. In addition, at such time, the Company shall
grant to Mr. Siegel a one-time warrant for the purchase of 223,000 shares of the
Company's Common Stock at an exercise price of $8.00 per share in the form
attached as Exhibit C. The warrant shall terminate five years from the date of
grant.

        2. MISCELLANEOUS. This Agreement may only be amended, waived, discharged
or terminated by means of an agreement in writing signed by the Company and
Robert Siegel. This Agreement represents the entire agreement between the
Company and Mr. Siegel and supersedes all prior agreements and understandings.
This Agreement shall bind and benefit the successors, assigns, heirs, executors
and administrators of the parties (including, without limitation, any successor
to the Company). The rights and obligations of Mr. Siegel under this Agreement
may not be assigned without the written consent of the Company, which shall not
be unreasonably withheld. This Agreement shall be governed in all respects by
the laws of the State of California. This Agreement may be executed in any
number of counterparts, each of which shall be an original, but all of which
together shall constitute one instrument.

        3. RELEASE OF COLLATERAL.

                A. The Company will release all pledged collateral at the
earlier of: the consummation of a sale or merger, an initial public offering,
private sale of equity ill excess of $5,000,000 or any debt offering in excess
of $5,000,000. If on December 15, 1996, the Company still owes a Claim under
this First Claim, the Company shall release the First Claim Holder's collateral
in full on that date. Upon such release, the First Claim Holder will release the
First Claim against all Company pledged assets simultaneously.

                B. All Claims due under this First Claim may be prepaid at the
time of merger/consolidation or the replacement of senior indebtedness. The
Company shall grant the First Claim holder a one time warrant to purchase
223,000 shares of Common Stock at a price of $8.00 per share.
<PAGE>   2
        4. SECURITY. This First Claim shall be secured pursuant to the terms of
a Security Agreement of even date herewith executed by First Claim Holder and
the Company attached hereto as Exhibit A (the "First Claim Agreement").
Additional rights of the holder of this First Claim are set forth in the First
Claim Agreement.

        5. ADJUSTMENTS AND OTHER PROVISIONS.

        5.1 ADJUSTMENTS FOR DIVIDENDS, COMBINATIONS, CONSOLIDATIONS, OR
SUBDIVISIONS. In the event (a) the holders of outstanding shares of the
Company's Common Stock shall receive, or become entitled to receive, without
payment therefor, other or additional Common Stock of the Company or (b) the
outstanding shares of the Company's Common Stock shall be combined, consolidated
or subdivided, by reclassification, exchange, substitution or otherwise, into a
lesser (or greater) number of shares of Common Stock, the number of shares of
Common Stock into which the attached Warrant Agreement Exhibit C will be
convertible immediately prior to such dividend, combination, consolidation or
subdivision will, concurrently with the effectiveness of such dividend,
combination, consolidation or subdivision, be proportionately adjusted.

        5.2 NO IMPAIRMENT. Except and to the extent waived or consented to by
the Holder, the Company will not, by amendment of its Articles of Incorporation
or through any reorganization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Company but will at all times in good faith assist
in the carrying out of all the provisions of this Agreement and in taking of all
such actions as may be necessary or appropriate in order to protect the rights
of the First Claim Holder against impairment.

        5.3 NOTICES OF RECORD DATE. Until the close of business on the earlier
of the three year Maturity Date or the date of the release of this First Claim,
if the Company fixes a record date for the purpose of determining the holders of
any class or series of securities who are entitled to receive any dividend
(other than a cash dividend which is the same as cash dividends paid in previous
quarters) or other distribution, the Company will mail to the First Claim
Holder, at least ten (10) days prior to such record date a notice specifying the
record date and the matter pursuant to which such record date has been set.

        6. ACCELERATION. Unless otherwise prohibited by law, if the Company
fails to meet any covenanted payment when due or upon the occurrence of any
event of default as defined in the Agreement, the holder of this First Claim
shall have the option, upon demand or notice, to declare the entire First Claim,
together with all interest accrued thereon, to be immediately due and payable.

<PAGE>   3
        7. INDEMNIFICATION. The Company agrees to indemnify Siegel for any and
all tax liabilities that result from the grant of this warrant. The Company also
agrees to pay up to two-thirds of the total taxes not to exceed a maximum tax
bracket of forty eight percent (48%) of the Three Hundred Fifty Five Thousand
Four Hundred Twenty Four Dollars and Ninety Nine Cents ($355,424.99) that will
be taxable upon the pledge of the collateral herein agreed to.

        $355,424.99 X 48%        = $170,604.00

        $170,604.00 /2/3         = $113,736.00

The Company agrees to pay $113,736.00 on or before September 30, 1996. In the
event that the Company's two-thirds portion of the realized taxation is less
than the $113,736 agreed to, Siegel agrees to reimburse the Company of the
difference within thirty days of realizing such an event. This provision
represents the entire indemnification of Siegel relating to this Agreement.

        8. SECOND CLAIM. At the Company's discretion the Company may pledge a
second claim or position in the Company's assets secured by Siegel.

        9. GENERAL PROVISIONS. This First Claim shall be governed by and
construed in accordance with the laws of the State of California. The Company
hereby waives presentment for payment, protest and demand, notice of protest,
demand and dishonor and nonpayment of this First Claim.


        IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first set forth above.

promulgated under the Exchange Act or any successor thereto ("Rule 16b-3") with

16b-3 with respect to a plan intended to qualify thereunder as a discretionary
plan. Once appointed, such Committee shall continue to serve in its designated
capacity until otherwise directed by the Board. From time to time the Board may
increase the size of the Committee and appoint additional members thereof,
remove members (with or without cause) and appoint new members in substitution
therefor, fill vacancies, however caused, and remove all members of the
Committee and thereafter directly administer the Plan, all to the extent
permitted by Rule 16b-3 with respect to a plan intended to qualify thereunder as

the Board, which committee shall be constituted in such a manner as to satisfy
the legal requirements relating to the administration of incentive stock option
plans, if any, of [state] corporate and securities laws, of the Code, and of any
applicable stock exchange (the "Applicable Laws"). Once appointed, such
Committee shall continue to serve in its designated capacity until otherwise
directed by the Board. From time to time the Board may increase the size of the
Committee and appoint additional members thereof, remove members (with or
without cause) and appoint new members in substitution therefor, fill vacancies,
however caused, and remove all members of the Committee and thereafter directly
administer the Plan, all to the extent permitted by the Applicable Laws.

                  (c) Powers of the Administrator. Subject to the provisions of
the Plan and, in the case of a Committee, the specific duties delegated by the
Board to such Committee, and subject to the approval of any relevant
authorities, including the approval, if required, of any stock exchange upon
which the Common Stock is listed, the Administrator shall have the authority, in
its discretion:

                      (i) to determine the Fair Market Value of the Common
Stock, in accordance with Section 2(k) of the Plan;

                      (ii) to select the Consultants and Employees to whom
Options and Stock Purchase Rights may from time to time be granted hereunder;

                      (iii) to determine whether and to what extent Options and
Stock Purchase Rights or any combination thereof are granted hereunder;

                      (iv) to determine the number of shares of Common Stock to
be covered by each such award granted hereunder;

                      (v) to approve forms of agreement for use under the Plan;

                      (vi) to determine the terms and conditions, not
inconsistent with the terms of the Plan, of any award granted hereunder;

                      (vii) to determine whether and under what circumstances an
Option may be settled in cash under subsection 9(f) instead of Common Stock;

                      (viii) to determine the terms and restrictions applicable
to Stock Purchase Rights and the Restricted Stock purchased by exercising such
Stock Purchase Rights; and

                      (x) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan.

                  (d) Effect of Administrator's Decision. All decisions,
determinations and interpretations of the Administrator shall be final and
binding on all Optionees and any other holders of any Options or Stock Purchase
Rights.

         5. Eligibility.

                  (a) Nonstatutory Stock Options and Stock Purchase Rights may
be granted to Employees and Consultants. Incentive Stock Options may be granted
only to Employees. An Employee or Consultant who has been granted an Option or
Stock Purchase Right may, if

                                       -5-
<PAGE>   6
he is otherwise eligible, be granted additional Options or Stock
Purchase Rights.

                  (b) Each Option shall be designated in the written option
agreement as either an Incentive Stock Option or a Nonstatutory Stock Option.
However, notwithstanding such designations, to the extent that the aggregate
Fair Market Value of the Shares with respect to which Options designated as
Incentive Stock Options are exercisable for the first time by any Optionee
during any calendar year (under all plans of the Company or any Parent or
Subsidiary) exceeds $100,000, such excess Options shall be treated as Nonstatu-
tory Stock Options.

                  (c) For purposes of Section 5(b), Incentive Stock Options
shall be taken into account in the order in which they were granted, and the
Fair Market Value of the Shares shall be determined as of the time the Option
with respect to such Shares is granted.

                  (d) The Plan shall not confer upon any Optionee any right with
respect to continuation of employment with the Company, nor shall it interfere
in any way with such Optionee's right or the Company's right to terminate his or
her employment at any time, with or without cause.

                  (e) The following limitations shall apply to grants of Options
to Officers:

                      (i) No Officer shall be granted, in any fiscal year of the
Company, Options to purchase more than 1,300,000 Shares; and

                      (ii) Over the remaining term of the Plan, no Officer shall
be granted Options to purchase more than 1,300,000 Shares.

         The foregoing limitations shall be adjusted proportionately in
connection with any change in the Company's capitalization as described in
Section 11(a).

         The limitations set forth in this Section 5(e) are intended to satisfy
the requirements applicable to Options intended to qualify as "performance-based
compensation" (within the meaning of Section 162(m) of the Code). In the event
the Administrator determines that such limitations are not required to qualify
Options as performance-based compensation, the Administrator may modify or
eliminate such limitations.

         6. Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company as described in Section 19 of the Plan. It shall
continue in effect for a term of

                                       -6-
<PAGE>   7
ten (10) years unless sooner terminated under Section 15 of the Plan.

         7. Term of Option. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof or such shorter term as may be
provided in the Option Agreement. However, in the case of an Option granted to
an Optionee who, at the time the Option is granted, owns stock representing more
than ten percent (10%) of the voting power of all classes of stock of the
Company or any Parent or Subsidiary, the term of the Option shall be five (5)
years from the date of grant thereof or such shorter term as may be provided in
the Option Agreement.

         8. Option Exercise Price and Consideration.

                  (a) The per share exercise price for the Shares to be issued
pursuant to exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

                     (i) In the case of an Incentive Stock Option

                         (A) granted to an Employee who, at the time of the
grant of such Incentive Stock Option, owns stock representing more than ten
percent (10%) of the voting power of all classes of stock of the Company or any
Parent or Subsidiary, the per Share exercise price shall be no less than 110% of
the Fair Market Value per Share on the date of grant.

                         (B) granted to any Employee, the per Share exercise
price shall be no less than 100% of the Fair Market Value per Share on the date
of grant.

                     (ii) In the case of a Nonstatutory Stock Option

                         (A) granted to a person who, at the time of the grant
of such Option, owns stock representing more than ten percent (10%) of the
voting power of all classes of stock of the Company or any Parent or Subsidiary,
the per Share exercise price shall be no less than 110% of the Fair Market Value
per Share on the date of the grant.

                         (B) granted to any person, the per Share exercise price
shall be no less than 85% of the Fair Market Value per Share on the date of
grant.

                  (b) The consideration to be paid for the Shares to be issued
upon exercise of an Option, including the method of payment, shall be determined
by the Administrator (and, in the case of an

                                       -7-
<PAGE>   8
Incentive Stock Option, shall be determined at the time of grant) and may
consist entirely of (1) cash, (2) check, (3) promissory note, (4) other Shares
that (x) in the case of Shares acquired upon exercise of an Option, have been
owned by the Optionee for more than six months on the date of surrender, and (y)
have a Fair Market Value on the date of surrender equal to the aggregate
exercise price of the Shares as to which such Option shall be exercised, (5)
delivery of a properly executed exercise notice together with such other
documentation as the Administrator and the broker, if applicable, shall require
to effect an exercise of the Option and delivery to the Company of the sale or
loan proceeds required to pay the exercise price, or (6) any combination of the
foregoing methods of payment. In making its determination as to the type of
consideration to accept, the Board shall consider if acceptance of such
consideration may be reasonably expected to benefit the Company.

         9. Exercise of Option.

                  (a) Procedure for Exercise: Rights as a Shareholder. Any
Option granted hereunder shall be exercisable at such times and under such
conditions as determined by the Board, including performance criteria with
respect to the Company and/or the Optionee, and as shall be permissible under
the terms of the Plan.

                  An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed to be exercised when written notice
of such exercise has been given to the Company in accordance with the terms of
the Option by the person entitled to exercise the Option and the Company has
received full payment for the Shares with respect to which the Option is
exercised. Full payment may, as authorized by the Board, consist of any
consideration and method of payment allowable under Section 8(b) of the Plan.
Until the issuance (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Shares, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 12 of the Plan.

                  Exercise of an Option in any manner shall result in a decrease
in the number of Shares that thereafter may be available, both for purposes of
the Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

                                       -8-
<PAGE>   9
         (b) Termination of Employment or Consulting Relationship. In the event
of termination of an Optionee's Continuous Status as an Employee or Consultant
with the Company (but not in the event of an Optionee's change of status from
Employee to Consultant (in which case an Employee's Incentive Stock Option shall
automatically convert to a Nonstatutory Stock Option on the day three months and
one day following such change of status) or from Consultant to Employee), such
Optionee may, but only within such period of time as is determined by the
Administrator, of at least thirty (30) days, with such determination in the case
of an Incentive Stock Option not exceeding three (3) months after the date of
such termination (but in no event later than the expiration date of the term of
such Option as set forth in the Option Agreement), exercise his or her Option to
the extent that Optionee was entitled to exercise it at the date of such
termination. To the extent that Optionee was not entitled to exercise the Option
at the date of such termination, or if Optionee does not exercise such Option to
the extent so entitled within the time specified herein, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

         (c) Disability of Optionee. In the event of termination of an
Optionee's consulting relationship or Continuous Status as an Employee as a
result of his or her disability, Optionee may, but only within six (6) months
from the date of such termination (but in no event later than the expiration
date of the term of such Option as set forth in the Option Agreement), exercise
the Option to the extent otherwise entitled to exercise it at the date of such
termination. In the event that the disability for which the Optionee is
terminated is not a "total and permanent disability" (as such term is defined in
Section 22(e)(3) of the Code), the Incentive Stock Option at issue will be
treated as a Nonstatutory Stock Option on and after the day three months and one
day following such termination. To the extent that Optionee was not entitled to
exercise the Option at the date of termination, or if Optionee does not exercise
such Option to the extent so entitled within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

         (d) Death of Optionee. In the event of the death of an Optionee, the
Option may be exercised at any time within six (6) months following the date of
death (but in no event later than the expiration of the term of such Option as
set forth in the Notice of Grant), by the Optionee's estate or by a person who
acquired the right to exercise the Option by bequest or inheritance, but only to
the extent that the Optionee was entitled to exercise the Option at the date of
death. If, at the time of death, the Optionee was not entitled to exercise his
or her entire Option, the Shares covered by the unexercisable portion of the
Option shall immediately revert to the Plan. If, after death, the Optionee's
estate or a person who acquired the right to exercise the Option by bequest or

                                       -9-
<PAGE>   10
inheritance does not exercise the Option within the time specified herein, the
Option shall terminate, and the Shares covered by such Option shall revert to
the Plan.

                  (e) Rule 16b-3. Options granted to persons subject to Section
16(b) of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

                  (f) Buyout Provisions. The Administrator may at any time offer
to buy out for a payment in cash or Shares, an Option previously granted, based
on such terms and conditions as the Administrator shall establish and
communicate to the Optionee at the time that such offer is made.

         10. Stock Purchase Rights.

                  (a) Rights to Purchase. Stock Purchase Rights may be issued
either alone, in addition to, or in tandem with other awards granted under the
Plan and/or cash awards made outside of the Plan. After the Administrator
determines that it will offer Stock Purchase Rights under the Plan, it shall
advise the offeree in writing of the terms, conditions and restrictions related
to the offer, including the number of Shares that such person shall be entitled
to purchase, the price to be paid, and the time within which such person must
accept such offer, which shall in no event exceed thirty (30) days from the date
upon which the Administrator made the determination to grant the Stock Purchase
Right. The offer shall be accepted by execution of a Restricted Stock purchase
agreement in the form determined by the Administrator. Shares purchased pursuant
to the grant of a Stock Purchase Right shall be referred to herein as
"Restricted Stock."

                  (b) Repurchase Option. Unless the Administrator determines
otherwise, the Restricted Stock purchase agreement shall grant the Company a
repurchase option exercisable upon the voluntary or involuntary termination of
the purchaser's employment with the Company for any reason (including death or
disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock purchase agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at such rate as the
Administrator may determine, but at a minimum rate of 20% per year.

                  (c) Other Provisions. The Restricted Stock purchase agreement
shall contain such other terms, provisions and conditions not inconsistent with
the Plan as may be determined by the Administrator in its sole discretion. In
addition, the provisions

                                      -10-
<PAGE>   11
of Restricted Stock purchase agreements need not be the same with respect to
each purchaser.

                  (d) Rights as a Shareholder. Once the Stock Purchase Right is
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 12
of the Plan.

         11. Stock Withholding to Satisfy Withholding Tax Obligations. At the
discretion of the Administrator, Employees or Consultants may satisfy
withholding obligations as provided in this paragraph. When an Employee or
Consultant incurs tax liability in connection with an Option or Stock Purchase
Right, which tax liability is subject to tax withholding under applicable tax
laws, and the Employee or Consultant is obligated to pay the Company an amount
required to be withheld under applicable tax laws, the Employee or Consultant
may satisfy the withholding tax obligation by one or some combination of the
following methods: (i) by cash payment, or (ii) out of Employee's or
Consultant's current compensation, (iii) if permitted by the Administrator, in
its discretion, by surrendering to the Company Shares that (a) in the case of
Shares previously acquired from the Company, have been owned by the Employee or
Consultant for more than six months on the date of surrender, and (b) have a
fair market value on the date of surrender equal to or less than Employee's or
Consultant's marginal tax rate times the ordinary income recognized, or (iv) by
electing to have the Company withhold from the Shares to be issued upon exercise
of the Option, or the Shares to be issued in connection with the Stock Purchase
Right, if any, that number of Shares having a fair market value equal to the
amount required to be withheld. For this purpose, the fair market value of the
Shares to be withheld shall be determined on the date that the amount of tax to
be withheld is to be determined (the "Tax Date").

         If the Employee or Consultant is subject to Section 16 of the Exchange
Act (an "Insider"), any surrender of previously owned Shares to satisfy tax
withholding obligations arising upon exercise of this Option must comply with
the applicable provisions of Rule 16b-3 promulgated under the Exchange Act
("Rule 16b-3") and shall be subject to such additional conditions or
restrictions as may be required thereunder to qualify for the maximum exemption
from Section 16 of the Exchange Act with respect to Plan transactions.

         All elections by an Employee or Consultant to have Shares withheld to
satisfy tax withholding obligations shall be made in writing in a form
acceptable to the Administrator and shall

                                      -11-
<PAGE>   12
be subject to the following restrictions:

                  (a) the election must be made on or prior to the applicable
Tax Date;

                  (b) once made; the election shall be irrevocable as to the
particular Shares of the Option or Stock Purchase Right as to which the election
is made;

                  (c) all elections shall be subject to the consent or
disapproval of the Administrator;

                  (d) if the Employee or Consultant is an Insider, the election
must comply with the applicable provisions of Rule 16b-3 and shall be subject to
such additional conditions or restrictions as may be required thereunder to
qualify for the maximum exemption from Section 16 of the Exchange Act with
respect to Plan transactions.

         In the event the election to have Shares withheld is made by an
Employee or Consultant and the Tax Date is deferred under Section 83 of the Code
because no election is filed under Section 83(b) of the Code, the Employee or
Consultant shall receive the full number of Shares with respect to which the
Option or Stock Purchase Right is exercised but such Employee or Consultant
shall be unconditionally obligated to tender back to the Company the proper
number of Shares on the Tax Date.

         12. Adjustments Upon Changes in Capitalization or Merger.

                  (a) Changes in Capitalization. Subject to any required action
by the shareholders of the Company, the number of shares of Common Stock covered
by each outstanding Option or Stock Purchase Right, and the number of shares of
Common Stock that have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or that have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, as well as the price per share of Common Stock covered by each
such outstanding Option or Stock Purchase Right, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of issued shares of Common Stock effected without receipt
of consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities

                                      -12-
<PAGE>   13
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
of Common Stock subject to an Option or Stock Purchase Right.

                  (b) Dissolution or Liquidation, or Asset Sale. In the event of
the proposed dissolution or liquidation of the Company, or the sale of all or
substantially all of the Company's assets, the Administrator shall notify the
persons holding Options or Stock Purchase Rights at least fifteen (15) days
prior to such proposed action. To the extent it has not been previously
exercised, the Option or Stock Purchase Right will terminate immediately prior
to the consummation of such proposed action.

                  (c) Merger. In the event of a merger of the Company with or
into another corporation, the Option or Stock Purchase Right shall be assumed or
an equivalent option or right shall be substituted by such successor corporation
or a parent or subsidiary of such successor corporation. If, in such event, the
Option or Stock Purchase Right is not assumed or substituted, the Option or
Stock Purchase Right shall terminate as of the date of the closing of the
merger. For the purposes of this paragraph, the Option or Stock Purchase Right
shall be considered assumed if, following the merger, the option or right
confers the right to purchase, for each Share of Optioned Stock subject to the
Option or Stock Purchase Right immediately prior to the merger, the
consideration (whether stock, cash, or other securities or property) received in
the merger by holders of Common Stock for each Share held on the effective date
of the transaction (and if holders were offered a choice of consideration, the
type of consideration chosen by the holders of a majority of the outstanding
Shares); provided, however, that if such consideration received in the merger
was not solely common stock of the successor corporation or its Parent, the
Administrator may, with the consent of the successor corporation, provide for
the consideration to be received upon the exercise of the Option or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, to be solely common stock of the successor corporation or its
Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger.

         13. Non-Transferability of Options and Stock Purchase Rights. Options
and Stock Purchase Rights may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee.

         14.      Time of Granting Options and Stock Purchase Rights.  The
date of grant of an Option or Stock Purchase Right shall, for all
purposes, be the date on which the Administrator makes the determi-

                                      -13-
<PAGE>   14
nation granting such Option or Stock Purchase Right, or such other date as is
determined by the Board. Notice of the determination shall be given to each
Employee or Consultant to whom an Option or Stock Purchase Right is so granted
within a reasonable time after the date of such grant.

         15. Amendment and Termination of the Plan.

                  (a) Amendment and Termination. The Board may at any time
amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation shall be made that would impair the rights of any
Optionee under any grant theretofore made, without his or her consent. In
addition, to the extent necessary and desirable to comply with Rule 16b-3 under
the Exchange Act or with Section 422 of the Code (or any other applicable law or
regulation, including the requirements of the NASD or an established stock
exchange), the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as required.

                  (b) Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

         16. Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the Shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

         As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

         17.      Reservation of Shares.  The Company, during the term of
this Plan, will at all times reserve and keep available such number
of Shares as shall be sufficient to satisfy the requirements of the
Plan.

                                      -14-
<PAGE>   15
         The inability of the Company to obtain authority from any regulatory
body having jurisdiction, which authority is deemed by the Company's counsel to
be necessary to the lawful issuance and sale of any Shares hereunder, shall
relieve the Company of any liability in respect of the failure to issue or sell
such Shares as to which such requisite authority shall not have been obtained.

         18. Agreements. Options and Stock Purchase Rights shall be evidenced by
written agreements in such form as the Board shall approve from time to time.

         19. Shareholder Approval. Continuance of the Plan shall be subject to
approval by the shareholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such shareholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any stock exchange upon which the Common Stock is listed.

         20. Information to Optionees and Purchasers. The Company shall provide
to each Optionee and to each individual who acquired Shares pursuant to the
Plan, during the period such Optionee or purchaser has one or more Options or
Stock Purchase Rights outstanding, and in the case of an individual who acquired
Shares pursuant to the Plan, during the period such individual owns such Shares,
(i) copies of all annual reports and other information which are provided to all
shareholders of the Company and (ii) at least annually, financial statements of
the Company, including a statement of operations for the most recent fiscal year
and a balance sheet as of the end of such fiscal year. The Company shall not be
required to provide such information to key employees whose duties in connection
with the Company assure their access to equivalent information.

                              EMPLOYMENT AGREEMENT

         This Employment Agreement (the "Agreement") is entered into this 15th
day of October, 1993, by and between U.S. Medical Instruments, Inc., a
California corporation (the "Company"), and Matthew S. Mazur (the "Executive").

                                    RECITAL

         The parties desire to set forth the terms of Executive's employment
with the Company.

         NOW, THEREFORE, the parties hereto agree as follows:

         1. Employment. The Company hereby employs the Executive and the
Executive hereby accepts employment upon the terms and conditions herein set
forth.

         2. Term.

                  (a) Basic Rule. The Company agrees to employ the Executive,
and the Executive agrees to remain in the employment with the Company, from the
effective date of this Agreement (the "Commencement Date") until the date when
the Executive's employment terminates pursuant to the provisions of this
Agreement.

                  (b) Early Termination. The Company may terminate the
Executive's employment by giving the Executive thirty (30) days' advance notice
in writing. If the Company terminates the Executive's employment for any reason
other than Cause or Disability, both as defined below, the provisions of Section
6(a) shall apply. The Executive may terminate his employment by giving the
Company thirty (30) days' advance notice in writing. If the Executive terminates
his employment under the preceding sentence, the provisions of Section 6(b)
shall apply. The Executive's rights under any applicable benefit plans or
programs shall be determined under the provisions of those plans or programs.
Any waiver of notice shall be valid only if it is made in writing and expressly
refers to the applicable notice requirement of this subsection 2(b).

                  (c) Death. The Executive's employment shall terminate in the
event of his death. The Company shall have no obligation to pay or provide any
compensation or benefits on account of the Executive's death, or for periods
following the Executive's death. The Executive's rights under the benefit plans
and programs of the Company in the event of the Executive's death shall be
determined under the provisions of those plans and programs.

                  (d) Cause. The Company may terminate the Executive's
employment for cause by giving the Executive thirty (30) days' advance notice in
writing. For all purposes under this Agreement, "Cause" shall mean (i) a willful
failure by the Executive to substantially perform his duties hereunder, other
than a failure resulting from the Executive's complete or partial incapacity due
to physical or mental illness or impairment, (ii) a willful act by the Executive
which constitutes gross misconduct and which is injurious to the Company, (iii)
a willful breach by the Executive of a material provision of this Agreement, or
(iv) a material and willful violation of a
<PAGE>   2
federal or state law or regulation applicable to the business of the Company. No
act, or failure to act, by the Executive shall be considered "willful" unless
committed without good faith without a reasonable belief that the act or
omission was in the Company's best interest. No compensation or benefits will be
paid or provided to the Executive on account of a termination for Cause, or for
periods following the date when such a termination of employment is effective.
The Executive's rights under the benefit plans or programs of the Company shall
be determined under the provisions of those plans or programs.

                  (e) Disability. The Company may terminate the Executive's
employment for Disability by giving the Executive thirty (30) days' advance
notice in writing. For all purposes under this Agreement, "Disability" shall
mean that the Executive, at the time notice is given, has been unable to
substantially perform his duties under this Agreement for a period of not less
than six (6) consecutive months as the result of his incapacity due to physical
or mental illness. In the event that the Executive resumes the performance of
substantially all of his duties hereunder before the termination of his

                  (a) Life Insurance. The Company will pay premiums on a life
insurance policy in the amount of $1,000,000, the beneficiary of which will be

directors to the maximum extent permitted by law, in which the Executive will be
included. The Company will commit contractually to advance any expenses for
which indemnification is available to the extent allowed by applicable law.

         6. Severance Benefits. If the Company terminates the Executive's
employment or if the Executive resigns his employment with the Company at any

<PAGE>   4
                  (a) Involuntary Termination. If the Executive's employment is
terminated by the Company, then the Executive (i) shall be entitled to receive
severance pay in an amount equal to thirty-six (36) months' Base Compensation;
provided, however, that such payments shall be reduced to the extent of any
other compensation that the Executive receives from a subsequent employer, and
the Company's obligation to pay severance shall cease in the event the Executive
obtains comparable new employment prior to the end of thirty-six (36) months.
Such payments shall be in lieu of any other severance or severance-type benefits
to which the Executive may be entitled under the Company's then existing benefit
plans and programs. Any severance payments to which the Executive is entitled
pursuant to this subsection (a) shall be paid periodically in accordance with
the Company's normal payroll.

                  (b) Resignation. In the event the Executive resigns his

Executive's employment.

         7. Successors. The Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption agreement
prior to the effectiveness of any such succession shall entitle the Executive to
the benefits described in subsection 6(a) of this Agreement, subject to the
terms and conditions therein.

         8. Arbitration/Governing Law. To the fullest extent permitted by law,
any dispute, claim or controversy of any kind (including but not limited to
tort, contract and statute) arising under, in connection with, or relating to
this Agreement or the Executive's employment, shall be resolved exclusively by
binding arbitration in San Diego, California in accordance with the commercial
rules of the American Arbitration Association then in effect. The Company and
the Executive agree to waive any objection to personal jurisdiction or venue in
any forum located in San Diego, California. No claim, lawsuit or action of any
kind may be filed by either party to this Agreement; arbitration is the
exclusive dispute resolution mechanism between the parties hereto. Judgment may
be entered on the arbitrator's award in any court having jurisdiction. The
validity, interpretation, effect and enforcement of this Agreement shall be
governed by the laws of the State of California.

         9. Proprietary Information. The Executive agrees to execute
confidentiality agreements as requested by the Company.

         10. Non-Solicit. The Executive covenants and agrees with the Company

other business enterprise with which the Executive may then be connected.

consulted with counsel and is fully aware of his rights and obligations under
this Agreement.

         12. Miscellaneous.

                  (a) Notices. Any notice required or permitted to be given
under this Agreement shall be sufficient if in writing and sent by registered
mail to the Executive at his residence as set forth on the Company's records, or
to the Company at its address set forth above, or such other addresses as either
party shall notify the other in accordance with the above procedure.

                  (b) Integration. This Agreement and the Exhibits hereto
represent the entire agreement and understanding between the parties as to the
subject matter hereof and supersede all prior or contemporaneous agreements
whether written or oral. No waiver, alteration, or modification of any of the
provisions of this Agreement shall be binding unless in writing and signed by
duly authorized representatives of the parties hereto.

                  (c) Waiver. Failure or delay on the part of either party
hereto to enforce any right, power, or privilege hereunder shall not be deemed
to constitute a waiver thereof. Additionally, a waiver by either party of a
breach of any promise hereof by the other party shall not operate as or be
construed to constitute a waiver of any subsequent waiver by such other party.

                  (d) Savings Clause. If any term, covenant, or condition of
this Agreement or the application thereof to any person or circumstance shall to
any extent be invalid or unenforceable, the remainder of this Agreement, or the
application of such term, covenant or condition to persons or circumstances
other than those as to which it is held invalid or unenforceable, shall not be
affected thereby and each term, covenant, or condition of this Agreement shall
be valid and enforced to the fullest extent permitted by law.

                  (e) Absence of Conflict. The Executive represents and warrants
that his employment by the Company as described herein shall not conflict with

relationship.

counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

1991, by and between Matthew S. Mazur, and individual residing at 2366
Columbia Street, San Diego, California 92103, hereinafter referred to as
"Licensor," and U.S. Medical Instruments, Inc., a California corporation,
having a principal office at 8950 Villa La Jolla Drive, Suite 220, San Diego,

                                  WITNESSETH:

        WHEREAS, Licensor is the owner of an application for United States
Patent for a Retractable Syringe With a Closed Barrel, (hereinafter referred to
as the Patent), which is listed on the attached Exhibit "A", and

        WHEREAS, Licensee desires to acquire exclusive rights and ownership in
the application for patent and any patents that may issue therefrom, including
patents for improvements in syringe products, under terms and conditions
hereinafter set forth.

        NOW, THEREFORE, in consideration of the premises and mutual
considerations herein set forth, the parties have agreed and do hereby agree as 
follows:

I.      GRANT OF RIGHTS IN PATENTS

        Licensor hereby grants to Licensee the worldwide exclusive right and
license to manufacture, have manufactured, use and sell, together with the
right to sublicense, products and methods disclosed in or covered by the
application (applications) for patent and patents that issue therefrom,
including patents issued on improvements in syringe products and methods. Such
products and methods hereinafter being referred to as the --Covered Products--.
Any subsequent patent applications filed that come under this Agreement shall
be added to Exhibit "A."

II.     ROYALTIES

        A. Licensee shall pay to Licensor a royalty of six percent (6%) of the
net selling price of the Covered Products until a total sum of Seven Hundred
and Fifty Thousand Dollars ($750,000.00) has been paid. The royalty thereafter
shall become three percent (3%).


                                       1
<PAGE>   2
        B. The minimum royalty per fiscal year under this Agreement shall be
three percent (3%) of the sales of the Covered Products for the previous
fiscal year, which minimum royalties shall begin with the date of this
Agreement and continue throughout the life of this Agreement. The minimum
royalty herein specified shall be paid by Licensee to Licensor each year even
though actual royalty sales for the respective year may be less. This minimum
royalty may be changed, from time to time, by agreement of the parties.

        C. The term "net selling price" is defined as the selling price not
including use, sales, excise or similar taxes imposed on the finished products.
A sale shall be deemed complete when the Covered Products are billed out upon
or after shipment. Credit for royalties paid or payable shall be allowed to
Licensee for defective or repossessed goods for which payment is credited or
returned to the purchaser. Where there is no bona fide sale or the Covered
Products are leased by Licensee, fair market value shall be substituted for net
sales price herein, or Licensee shall pay royalties on the lease income,
whichever shall be elected by Licensor.

III. ASSIGNMENT

        A. At any time at Licensor's sole election, Licensor shall have the
right to sell and assign all right, title and interest in said application for
patent, see Exhibit "A," and any patents issuing therefrom, to Licensee under
the Assignment form attached hereto as Exhibit "B."

        B. Upon any such assignment, Licensor waives the right to payment of
royalties under Article II. ROYALTIES of this Agreement, and in place thereof
shall receive a payment of one million dollars ($1,000,000) U.S., which amount
shall be paid by Licensee to Licensor in a lump sum within three (3) years from
the date of this Agreement, or at the election of Licensee shall be paid in
eight (8) yearly installments of one hundred and twenty-five thousand dollars
($125,000) U.S. per year with each installment being paid on the 2nd day of
January of each year, with interest on the unpaid balance being paid each year
at two points above prime.

        C. If the installment payment plan is elected by Licensee, then the
first payment of one hundred and twenty-five thousand dollars ($125,000) U.S.
shall be paid on January 2, 1994, with interest on the unpaid balance beginning
on that date.

IV. SUBLICENSES

        In exercising its right to sublicense under this Agreement, Licensee
shall be obligated to Licensor solely to the extent that sales made by the
sublicensee shall constitute sales subject to the royalty provisions of this
Agreement and such sales shall be included in the quarterly reports rendered by 
Licensee.

                                       2
<PAGE>   3
V.      RECORDS AND REPORTS

        Licensee agrees to keep true and full records of the Covered Products
manufactured and sold which records shall be open to inspection by Licensor at
reasonable times.

days of one January, one April, one July and one October of each year setting
forth the Covered Products sold during the quarterly period terminating on the
first day of said months, this statement to be rendered even though no sales,
leases or uses were made during such quarterly period.

        Licensee agrees to pay concurrently with the rendition of said statement
the royalties accruing during the particular quarterly period.

VI.     BUSINESSLIKE EFFORTS

        Licensee agrees to exert reasonable businesslike efforts to promote the
sale of Covered Products and actively engage in the manufacture and sale
thereof and satisfy the demand therefor. The amount of minimum royalties paid
under Paragraph II.B shall not, by itself, satisfy this requirement of exerting
reasonable businesslike efforts.

VII.    TERM

        This Agreement shall extend to the full term of any of the subject
patents in Exhibit "A" unless earlier terminated in accordance with the
provision hereof.

VIII.   SUIT OF INFRINGERS

        Licensor grants to Licensee the right to bring suit for any patent
infringement relating to the Covered Products. In any such suit, Licensor
agrees to assist Licensee in any way deemed necessary by Licensee toward the
