                                  THE COMPANY
 
    Vista Medical Technologies, Inc. ("Vista Medical" or the "Company")
develops, manufactures and intends to market proprietary visualization and
information systems that enable minimally invasive surgical solutions in
cardiothoracic, head, neck and spine ("HNS") and other selected microsurgical
procedures. The Company currently markets three-chip cameras for endoscopy and
related surgical instruments and accessories. Vista Medical's visualization and
information systems bring together head-mounted display ("HMD") technology
originally developed for applications in military aerospace by Kaiser Aerospace
and Electronics Corporation ("Kaiser Aerospace") and three-dimensional ("3-D")
imaging capability from its acquisition of Oktas, Inc.
 
    The development and subsequent widespread adoption of minimally invasive
surgical approaches have revolutionized many surgical fields, including general
surgery, orthopedics, gynecology and urology. Minimally invasive surgical
procedures are performed through strategically placed ports or mini-incisions in
a patient's body, thereby avoiding the larger incisions used in traditional open
surgery. Minimally invasive procedures are designed to decrease complications,
reduce pain and suffering, speed recovery and decrease costs associated with
many aspects of patient care. This movement toward minimally invasive surgery
has been driven by advances in both device technology and surgical technique.
Minimally invasive microsurgery ("MIM") is an extension of minimally invasive
surgery and is characterized by greater complexity and precision. MIM procedures
have been made possible primarily by recent advances in medical technology.
 
    The application of minimally invasive techniques to cardiothoracic surgery
is commonly regarded as a revolutionary development in modern surgery. Minimally
invasive cardiac procedures avoid the trauma caused by sternotomy and promise to
significantly decrease pain and trauma and shorten recovery times.
Cardiothoracic MIM requires the surgeon to perform technically challenging
procedures, including working on tiny delicate structures (such as a one
millimeter heart vessel) with highly restricted access through small incisions.
 
    The Company believes that an advanced visualization technology which
provides the surgeon with an intuitive and ergonomic solution to the inherent
vision restrictions of the MIM approach will enable the use of the MIM technique
with increased safety, efficacy and precision. In order to meet this
visualization challenge, the Company has developed proprietary visualization and
information systems.
 
    Vista Medical's proprietary technology is based on the following principles
which the Company believes are essential in advancing the techniques of MIM: (i)
three-dimensional view; (ii) high resolution images; (iii) improved access
through miniaturization technology; (iv) optimized surgical ergonomics; and (v)
integration of anatomical image with critical monitoring and diagnostic
information.
 
                                       3
<PAGE>
    Based on these principles, Vista Medical develops visualization products and
related information systems that are customized for the specific cardiothoracic
and HNS procedures to which they are directed. The Company's product lines
include the Series 8000 Advanced Visualization and Information System ("Series
8000"), designed for use in cardiothoracic procedures, and StereoSite, designed
for use in microscopic and endoscopic procedures in HNS. The Company also offers
surgical instruments and accessories designed for use in both cardiothoracic and
HNS MIM procedures.
 
BUSINESS STRATEGY
 
    The Company's business strategy is to become the leading developer and
marketer of advanced visualization and information systems for MIM applications
in cardiothoracic, HNS and other selected surgical specialties. Key elements of
the Company's strategy include:
 
    - Establish advanced visualization technologies as standard practice in
      minimally invasive cardiac surgery.
 
    - Promote Vista Medical's visualization solution for use in all types of
      cardiac surgery.
 
    - Develop MIM applications through specialty-focused business units by
      leveraging the Company's technology platform.
 
    - Accelerate adoption of the Series 8000 Advanced Visualization and
      Information System in the cardiac market by implementing a per-procedure
      pricing strategy.
 
    - Increase the surgeon's real-time access to critical data.
 
    - Enter into strategic relationships which complement Company resources.
 
    To assist in implementing its business strategy, the Company has established
two Clinical Advisory Boards made up of leading surgeons, one focused on
minimally invasive cardiac surgery, the other focused on HNS microsurgery and a
number of other specialties. Members of the Clinical Advisory Boards consult
with the Company exclusively in the field of visualization. The Clinical
Advisory Boards are intended to act as a clinical reference for the Company and
to provide access to potential training sites for the Company's visualization
products.
 
RECENT DEVELOPMENTS
 
    In November 1996, Vista Medical and Medtronic, Inc. ("Medtronic"), a leading
cardiac company, entered into a strategic alliance providing for the
distribution and co-promotion of the Company's current and future visualization
and information systems for cardiac surgery, including the Series 8000 (the
"Vista Systems"). Medtronic will act as Vista Medical's exclusive distributor
for the Vista Systems for use in cardiothoracic surgical procedures in Europe,
the Middle East (excluding Afghanistan and Pakistan) and Africa and will
co-promote the Vista Systems in North America. Vista Medical retains direct
distribution rights in North America as well as the worldwide right to
distribute its systems for use in all other procedures. In conjunction with
entering into the agreement, Medtronic made a $10.0 million equity investment in
the Company.
 
    The Company believes that the control and processing of information is a key
component in the development of advanced visualization systems. As a result, in
February 1997, the Company obtained from GDE Systems, Inc. ("GDE"), a leading
military electronics and information management company, an exclusive worldwide
license to software and documentation and trademarks of GDE for use in the
medical field. Since 1993, GDE's subsidiary, Healthcom, has been adapting the
software licensed to Vista Medical to provide high-speed, image-based
information processing and networking capabilities specifically for medical
applications. In connection with the license, Vista Medical will issue to GDE
Common Stock with a value (based on the initial public offering price) of
$250,000.
 
                                       4
<PAGE>
    In February 1997, the Company entered into an agreement with Heartport, Inc.
("Heartport"), a leading company developing minimally invasive technology for
heart surgery. Vista Medical will sell four Series 8000 systems to Heartport,
for use in the Heartport Research and Training Center in Salt Lake City, Utah.
Heartport has agreed to use the Series 8000 in its training centers, to promote
that its training courses utilize the Series 8000 and to endorse the Series 8000
as the preferred 3-D video visualization and information solution for minimally
invasive heart surgery. In connection with the agreement, the Company issued to
Heartport a warrant to purchase up to 100,000 shares of Common Stock,
exercisable at any time after this Offering and prior to March 31, 2001, at a
price per share equal to the initial public offering price.
 
    The Company believes that all of its products or products under development
are, or will be, eligible for 510(k) clearance to market by the United States
Food and Drug Administration ("FDA"). Applications for 510(k) clearance to
market have been filed, or clearance to market has been received, for all
components which are necessary for initial Series 8000 commercialization. The
Company believes that there are predicate devices which can be relied upon for
those of its products for which regulatory applications are in process. A
majority of these predicate devices were developed by the Company or its
strategic partners.

                                  RISK FACTORS
 
    AN INVESTMENT IN THE SHARES OF COMMON STOCK OFFERED HEREBY INVOLVES A HIGH
DEGREE OF RISK. THE FOLLOWING FACTORS, IN ADDITION TO THE OTHER INFORMATION
CONTAINED IN THIS PROSPECTUS, SHOULD BE CAREFULLY CONSIDERED IN EVALUATING THE
COMPANY AND ITS BUSINESS BEFORE PURCHASING SHARES OF COMMON STOCK OFFERED
HEREBY. THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS
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 THOSE DISCUSSED BELOW.
 
DEVELOPMENT STAGE COMPANY; SUBSTANTIAL FUTURE LOSSES AND FUTURE CAPITAL
  REQUIREMENTS
 
    Since its formation in July 1993, the Company has been engaged in the
development of visualization and information systems and related surgical
instruments and accessories that enable MIM solutions for applications in
cardiothoracic and other selected microsurgical procedures and in manufacturing
and marketing limited quantities of camera systems to customers as an original
equipment manufacturer ("OEM"). As of December 31, 1996, the Company had
incurred cumulative net losses of $13.6 million since its formation. The Company
expects to incur substantial and increasing operating losses before it will
reach profitability, if at all. Furthermore, the Company expects its expenses in
all categories to increase as its marketing and other business activities
expand. There can be no assurance that the Company will achieve or sustain
profitability in the future. Failure to achieve significant commercial revenues
or profitability would have a material adverse effect on the Company's business,
financial condition and results of operations.
 
    The Company's future liquidity and capital requirements will depend upon
numerous factors, including the following: the extent to which the Company's
products gain market acceptance; the progress and scope of product evaluations;
the timing and costs of filing future regulatory submissions; the timing and
costs required to receive both domestic and international governmental
approvals; the timing and costs of product introductions; the extent of the
Company's ongoing research and development programs; the costs of training
physicians to become proficient in the use of the Company's products and
procedures; and the costs of developing marketing and distribution capabilities,
if regulatory approvals are received. If the net proceeds of this Offering,
together with available funds and cash generated from operations, are
insufficient to satisfy the Company's cash needs, the Company may require
additional financing. There can be no assurance that such additional financing
will be available on terms acceptable to the Company, if at all. The Company's
inability to fund its capital and operational requirements would have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
DEPENDENCE UPON AND UNCERTAINTY REGARDING COMMERCIALIZATION OF SERIES 8000
 
    The Series 8000 for minimally invasive cardiac surgery is the Company's
primary near-term product focus and is expected to account for the majority of
the Company's revenues over the next several years. Some components of the
system have not been cleared for marketing by the FDA. Additional product
evaluation, as well as regulatory clearance or approval, is required before the
system can be widely marketed in the United States or internationally. There can
be no assurance that demand for the Series 8000 will be sufficient to achieve
profitable operations.
 
    Development of certain peripheral components of the Series 8000 has not yet
been finalized, and final prototypes have not yet been completed. There can be
no assurance that such development efforts will be successful or that the
Company's products under development will be shown to be safe or effective,
capable of being manufactured in commercial quantities at acceptable costs,
cleared or approved by regulatory authorities or successfully marketed.
 
                                       7
<PAGE>
    Evaluations of the Series 8000 conducted to date have shown that there is a
learning process involved for surgeons and other members of the surgery team to
become proficient with the use of the system. Based on a limited number of
clinical and laboratory procedures performed to date, there can be no assurance
that visualization and information system enhancements incorporated, or to be
incorporated, in the Series 8000 will prove suitable for use by a substantial
number of cardiothoracic surgeons. If the Series 8000 proves unsuitable for a
number of surgeons to use, the potential markets and applications for the
Company's products would be significantly limited. Widespread use of the Series
8000 will require training of a large number of surgeons, and the time required
to institute a training program and to train such surgeons could adversely
affect market acceptance. Failure to successfully commercialize the Series 8000
would have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business -- Product Lines," "Business
- -- Marketing and Sales," "Business -- Manufacturing" and "Business -- Government
Regulation."
 
UNCERTAINTY OF CLINICAL ADOPTION OF MINIMALLY INVASIVE MICROSURGICAL PROCEDURES
 
    The Company's near-term products are being developed in order to enable
cardiothoracic and HNS surgeons to perform MIM surgical procedures using their
existing skills coupled with training and complementary equipment being
developed by other companies. Accordingly, the Company's success is dependent
upon acceptance of these procedures by the medical community as a reliable, safe
and cost effective alternative to existing treatments. To date, MIM surgical
procedures have only been performed on a very limited basis by a small number of
highly skilled surgeons. The Company is unable to predict how quickly, if at
all, MIM surgical procedures will be adopted by the medical community or, if
they are adopted, the number of procedures that will be performed.
 
    Most patients with cardiovascular disease first consult with a cardiologist,
who then may treat the patient with pharmaceuticals or non-surgical
interventions, such as angioplasty and intravascular stents, or refer the
patient to a cardiac surgeon for open-chest coronary artery bypass graft
("CABG") surgery. Cardiologists may not recommend MIM procedures until such
time, if at all, as such procedures can successfully be demonstrated to be as
safe and cost-effective as other accepted treatments. In addition, cardiac
surgeons may choose not to recommend MIM procedures until such time, if at all,
as such procedures are proven to be more efficacious than conventional,
open-chest surgery methods, which have become widely adopted by cardiac surgeons
since the initial use of such surgery in the mid-1950s.
 
    Even if the clinical efficacy of MIM procedures is established in cardiac
and other specialties, surgeons, specialists and other physicians may choose not
to recommend the procedures for any number of other reasons. Clinical adoption
will depend, for example, upon the Company's ability to facilitate training of
surgeons to perform MIM surgery and the willingness of such surgeons to perform
such procedures. Physicians may similarly elect not to recommend the MIM
procedure based on possible unavailability of acceptable reimbursement from
health care payors. Health care payor acceptance may require evidence of the
cost effectiveness of MIM procedures as compared to other currently available
treatments. The Company believes that physician endorsements will be essential
for clinical adoption of MIM procedures, and there can be no assurance that any
such endorsements will be obtained in a timely manner, if at all. Patient
acceptance of the procedure will depend upon such physician recommendations, as
well as other factors, including the effectiveness of, and the rate and severity
of complications associated with, the procedure as compared to other treatments.
 
    There can be no assurance that MIM procedures will gain clinical adoption.
Failure of these procedures to achieve significant clinical adoption would have
a material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Background," "Business -- Product
Lines," "Business -- Marketing and Sales," "Business -- Competition" and
"Business -- Government Regulation."
 
                                       8
<PAGE>
LACK OF COMMERCIAL MANUFACTURING EXPERIENCE; SCALE-UP RISK
 
    The Company lacks experience in manufacturing the products under
development, including the Series 8000, in the quantities that would be
necessary for the Company to achieve significant commercial sales. The
manufacture of the Company's products primarily involves the assembly of a
number of sub-assemblies and components. Companies such as Vista Medical often
encounter difficulties in scaling up manufacturing of products, which
difficulties could include problems involving quality control and assurance,
component and service availability, adequacy of control policies and procedures,
lack of qualified personnel, compliance with FDA regulations and the need for
further FDA approval of new manufacturing processes and facilities and other
production constraints. There can be no assurance that reliable, high-volume
manufacturing can be established or maintained at commercially reasonable costs.
The Company will also require additional manufacturing facilities as production
volumes increase; acquisition of new manufacturing facilities will likely
involve relocation. Any of these factors could have a material adverse effect on
the Company's business, financial condition and results of operation.
 
    The Company has and will continue to consider as appropriate, the internal
manufacture of sub-assemblies currently provided by third party subcontractors,
as well as the implementation of new production processes. There can be no
assurance that manufacturing yields or costs will not be adversely affected by
the transition to in-house production or to new production processes when such
efforts are undertaken, or that FDA Good Manufacturing Practices ("GMP")
requirements can be met and that such a transition would not materially
adversely affect the Company's business, financial condition and results of
operations. See "Business -- Manufacturing."
 
LIMITED SALES, MARKETING, DISTRIBUTION AND TECHNICAL SUPPORT EXPERIENCE
 
    The Company has organized its sales and marketing efforts by the Company's
CardioThoracic Surgery and HNS Microsurgery divisions. The Company currently
markets its cardiothoracic products in North America through two direct (Company
employee) sales representatives and 35 independent sales representatives. The
Company is in the process of hiring up to 10 additional direct sales
representatives to support the introduction of its Series 8000 by the
CardioThoracic Surgery division. A similar combination of direct and independent
sales representatives will market the products of the Company's HNS Microsurgery
division. Establishment of a sales force capable of effectively commercializing
the Company's systems will require substantial efforts and significant
management and financial resources. There can be no assurance that the Company
will be able to establish such a sales capability on a timely basis or at all.
 
    The Company believes that a critical element of its sales efforts in North
America will be the provision of technical support, including training and
clinical validation efforts, to its customers. Provision of an adequate level of
such support on a timely basis requires significant financial resources. There
can be no assurance that the Company will be able to provide an adequate level
of technical support on a timely basis, or at all. See "Business -- Strategic
Alliances" and "Business -- Marketing and Sales."
 
POTENTIAL COMPONENT SHORTAGES; DEPENDENCE ON SOLE SOURCES OF SUPPLY
 
    The Company uses or relies on certain components and services used in its
systems that are provided by sole source suppliers. The manufacture of the
Company's products in larger commercial quantities will require a substantial
increase in component supplies and will likely necessitate the replacement of
current suppliers or the addition of new suppliers. The qualification of
additional or replacement vendors for certain components or services is a
lengthy process. In addition, the substitution of replacement vendors may entail
re-engineering time and cost and could delay the supply of the Company's
products.
 
    The Company expects to manufacture its products based on forecasted product
orders and intends to purchase subassemblies and components prior to receipt of
purchase orders from customers. Lead
 
                                       9
<PAGE>
times for materials and components ordered by the Company vary significantly and
depend on factors such as the business practices of the specific supplier,
contract terms and general demand for a component at a given time. Certain
components used in the Company's products have long lead times. As a result,
there is a risk of excess or inadequate inventory if orders do not match
forecasts.
 
    Any significant supply interruption, or inventory shortage or overage, would
have a material adverse effect on the Company's ability to manufacture the
Company's products and, therefore, a material adverse effect on its business,
financial condition and results of operations. See "Business -- Manufacturing."
 
NO ASSURANCE OF REGULATORY CLEARANCE OR APPROVAL; SIGNIFICANT DOMESTIC AND
  INTERNATIONAL REGULATION
 
    The manufacture and sale of medical devices intended for commercial
distribution are subject to extensive governmental regulation in the United
States. Medical devices are regulated in the United States primarily by the FDA
and, to a lesser extent, by certain state agencies. Generally, medical devices
require pre-market clearance or pre-market approval prior to commercial
distribution. In addition, certain material changes or modifications to medical
devices also are subject to FDA review and clearance or approval. The FDA
regulates the research, testing, manufacture, safety, labeling, storage, record
keeping, promotion and distribution of medical devices in the United States and
the export of unapproved medical devices from the United States to other
countries. Noncompliance with applicable requirements can result in failure of
the government to grant pre-market clearance or approval for devices, withdrawal
of approval, total or partial suspension of production, fines, injunctions,
civil penalties, refunds, recall or seizure of products and criminal
prosecution.
 
    In the United States, medical devices are classified into one of three
classes, Class I, II or III, on the basis of the controls deemed by the FDA to
be necessary to reasonably ensure their safety and effectiveness. The Company's
products to date have either been classified as Class I or Class II devices.
 
    Class I devices are subject to general controls (e.g., established
registration and product listing, labeling, adulteration and misbranding
provisions and medical device reporting requirements and, unless exempt, to
pre-market notification and adherence to GMP standards). Class II devices are
subject to general controls and special controls (e.g., performance standards,
post-market surveillance, patient registries and FDA guidelines). Generally,
Class III devices are those that must receive pre-market approval by the FDA to
ensure their safety and effectiveness (e.g., life-sustaining, life-supporting
and implantable or new devices which have not been found to be substantially
equivalent to legally marketed devices). Class III devices ordinarily require
clinical testing to ensure safety and effectiveness and FDA approval prior to
marketing and distribution. The FDA also has the authority to require clinical
testing of Class I and Class II devices. A pre-market approval ("PMA")
application must be filed if a proposed device is not substantially equivalent
to a legally marketed predicate device or if it is a Class III device for which
the FDA has called for such application. A PMA typically takes several years to
be approved by the FDA.
 
    Generally, before a new device can be introduced into the market in the
United States, the manufacturer or distributor must obtain FDA clearance of a
510(k) notification or submission and approval of a PMA application. If a
medical device manufacturer or distributor can establish that a device is
"substantially equivalent" to a legally marketed Class I or Class II device, or
to a Class III device for which the FDA has not called for a PMA, the
manufacturer or distributor may seek clearance from the FDA to market the device
by filing a 510(k) notification. The 510(k) notification may need to be
supported by appropriate performance, clinical or testing data establishing the
claim of substantial equivalence. The FDA requires a rigorous demonstration of
substantial equivalence.
 
    Following submission of the 510(k) notification, the manufacturer or
distributor may not place the device into commercial distribution until a letter
clearing the 510(k) is issued by the FDA. At this time, the
 
                                       10
<PAGE>
FDA typically responds to the submission of a 510(k) notification within 90 to
200 days. An FDA letter may declare that the device is substantially equivalent
to a legally marketed device and allow the proposed device to be marketed in the
United States. The FDA, however, may determine that the proposed device is not
substantially equivalent or requires further information, including clinical
data, to make a determination regarding substantial equivalence. Such
determination or request for additional information will delay market
introduction of the product that is the subject of the 510(k) notification.
 
    All clinical investigations involving the use of an unapproved or uncleared
device on humans to determine the safety or effectiveness of the device must be
conducted in accordance with the FDA's investigational device exemption ("IDE")
regulations. If the device presents a "significant risk," the manufacturer or
distributor of the device is required to file an IDE application with the FDA
prior to commencing human clinical trials. The IDE application must be supported
by data, typically the result of animal and, possibly, mechanical testing. If
the IDE application is approved by the FDA, human clinical trials may begin at a
specific number of investigational sites with a maximum number of patients, as
approved by the FDA. If the device presents a "non-significant risk," approval
by an Institutional Review Board prior to commencing human clinical trials is
required, as well as compliance with labeling, record keeping, monitoring and
other requirements.
 
    Any products manufactured or distributed by the Company are subject to
continuing regulation by the FDA, which includes record keeping requirements,
reporting of adverse experience with the use of the device GMP requirements and
post-market surveillance, and may include post-market registry and other actions
deemed necessary by the FDA. A 510(k) supplement, new 510(k) or PMA is also
required when a medical device manufacturer makes a change or modification to a
legally marketed device that could significantly affect the safety or
effectiveness of the device, or where there is a major change or modification in
the intended use of the device. When any change or modification is made to a
device or its intended use, the manufacturer is expected to make the initial
determination as to whether the change or modification is of a kind that would
necessitate the filing of a 510(k) supplement, new 510(K) or PMA.
 
    Sales of medical device products outside the United States are subject to
foreign regulatory requirements that vary from country to country. The time
required to obtain approvals required by foreign countries may be longer or
shorter than that required for FDA clearance, and requirements for licensing may
differ from FDA requirements. Failure to comply with regulatory requirements
could have a material adverse effect on the Company's business, financial
condition and results of operations. The current regulatory environment in
Europe for medical devices differs significantly from that in the United States.
Europe is currently in the transitional process of implementing the Medical
Device Directive which was adopted on January 1, 1995 with a transition period
through June 1998. After June 1998, all medical devices sold in the European
Union must bear the CE mark. Devices are now classified by manufacturers
according to the risks they represent with a classification system giving Class
III as the highest risk devices and Class I as the lowest. Once the device has
been classified, the manufacturer can follow one of a series of conformity
assessment routes, typically through a registered quality system, and
demonstrate compliance to a European Notified Body. After that, the CE mark may
be applied to the device. Maintenance of the system is ensured through annual
on-site audits by the Notified Body and a post-market surveillance system
requiring the manufacturer to submit serious complaints to the appropriate
governmental authority.
 
    Failure to comply with regulatory requirements could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Business -- Government Regulation."
 
RAPID TECHNOLOGICAL CHANGE; SIGNIFICANT COMPETITION
 
    The medical device market is characterized by intensive development efforts
and rapidly advancing technology. The future success of the Company will depend,
in large part, upon its ability to anticipate and keep pace with advancing
technology and competing innovations. There can be no assurance,
 
                                       11
<PAGE>
however, that the Company will be successful in identifying, developing and
marketing new products or enhancing its existing products.
 
    The Company believes that a number of large companies, with significantly
greater financial, manufacturing, marketing, distribution and technical
resources and experience than that of the Company, are focusing on the
development of visualization products for MIM. Several companies are currently
developing and marketing visualization products for MIM which could be applied
to cardiac surgery. There can be no assurance that the Company will be
successful in competing with any such companies.
 
    Technological advances with other therapies for heart disease such as drugs,
interventional cardiology procedures or future innovations in cardiac surgery
techniques could make such other therapies more effective or lower in cost than
MIM surgical procedures and could render MIM cardiac surgery obsolete.
 
    There can be no assurance that physicians will use MIM surgical procedures
to replace or supplement established treatments, such as conventional open-chest
heart surgery, angioplasty or intravascular stents, or that MIM cardiac surgery
will be competitive with current or future technologies. There can be no
assurance that the Company will be able to compete successfully against current
and future competitors. Failure to do so would have a material adverse effect
upon the Company's business, financial condition and results of operations. See
"Business -- Competition."
 
RELIANCE ON STRATEGIC RELATIONSHIPS
 
    The Company intends to pursue strategic relationships with corporations and
research institutions with respect to the research, development, regulatory
approval and marketing of certain of its products. The Company's future success
may depend, in part, on its relationships with such partners, including, for
example, the Company's relationships with Medtronic and Heartport. The Company
will have limited or no control over the resources that any partner may devote
to the Company's products, or over partners' development and marketing efforts.
There can be no assurance that any of the Company's present or future
collaborative partners will perform their obligations as expected or will devote
sufficient resources to the development or marketing of the Company's potential
products. Any parallel development by a partner of alternate technologies,
preclusion from entering into competitive arrangements, failure to obtain timely
regulatory approvals, premature termination of a collaborative agreement or
failure by a partner to devote sufficient resources to the development and
commercialization of the Company's products would have a material adverse effect
on the Company's business, financial condition and results of operations. The
Company anticipates that these partners may have the unilateral right to
terminate any such relationship without significant penalty. There can be no
assurance that the Company will be successful in establishing or maintaining any
such strategic relationships in the future or that any such relationship will be
successful. See "Business -- Strategic Alliances."
 
FLUCTUATIONS IN OPERATING RESULTS
 
    Results of operations of the Company may vary significantly from quarter to
quarter depending upon numerous factors, including the following: timing and
results of product evaluations; delays associated with the FDA and other
regulatory approval processes; demand for and utilization of the Company's
products; changes in pricing policies by the Company or its competitors; the
number, timing and significance of product enhancements and new product
announcements by the Company and its competitors; the ability of the Company to
develop, introduce and market new and enhanced versions of the Company's
products on a timely basis; customer order deferrals in anticipation of
enhancements or new products offered by the Company or its competitors; product
quality problems; personnel changes; and the level of international sales. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."
 
                                       12
<PAGE>
UNCERTAINTY RELATING TO THIRD-PARTY PAYMENTS
 
    The Company expects that sales volumes and prices of the Company's products
will be directly influenced by the profitability to, or cost-effectiveness for,
hospitals of the procedures in which the Company's products are involved.
Profitability levels are directly related to the level of payments for these
procedures, either by Medicare or private insurance companies, and it is a
continuing trend in U.S. health care for such payments to be under continual
scrutiny and downward pressure. The Company expects that its products typically
will be used by hospitals and surgical centers, which bill various third-party
payors, such as governmental programs and private insurance plans, for the
health care services provided to their patients. Third-party payors carefully
review and increasingly challenge the prices charged for medical products and
services or negotiate a flat rate fee in advance. Payment rates from private
companies also vary depending on the procedure performed, the third-party payor,
the insurance plan and other factors. Medicare compensates hospitals at a
prospectively determined fixed amount for the costs associated with an
in-patient hospitalization based on the patient's discharge diagnosis and
compensates physicians at a prospectively determined fixed amount based on the
procedure performed, regardless of the actual costs incurred by the hospital or
physician in furnishing the care and unrelated to the specific devices or
systems used in that procedure. Medicare and other third-party payors are
increasingly scrutinizing whether to cover new products and the level of payment
for new procedures. The flat fee reimbursement trend is causing hospitals to
control costs strictly in the context of a managed care system in which health
care providers contract to provide comprehensive health care for a fixed cost
per person. The Company is unable to predict what changes will be made in the
reimbursement methods utilized by third-party health care payors. The Company
could be adversely affected by changes in payment policies of government or
private health care payors, particularly to the extent any such changes affect
payment for the procedure in which the Company's products are intended to be
used.
 
    If the Company obtains the necessary foreign regulatory registrations or
approvals, market acceptance of the Company's products in international markets
would be dependent, in part, upon the acceptance by the prevailing health care
financing system in each country. Health care financing systems in international
markets vary significantly by country and include both government sponsored
health care programs and private insurance. There can be no assurance that these
financing systems will endorse use of the Company's technology.
 
    The Company believes that reimbursement in the future will be subject to
increased restrictions such as those described above, both in the United States
and in foreign markets. The Company believes that the overall escalating cost of
medical products and services has led to and will continue to lead to increased
pressures on the health care industry, both foreign and domestic, to reduce the
cost of products and services, including products offered by the Company. There
can be no assurance, as to either United States or foreign markets, that funding
will be available or adequate, or that future legislation, regulation or
reimbursement policies of third-party payors will not otherwise adversely affect
the demand for the Company's products or its ability to sell its products on a
profitable basis, particularly if the Company's systems are more expensive than
competing surgical procedures. The unavailability or inadequacy of third-party
payor coverage or reimbursement would have a material adverse effect on the
Company's business, financial condition and results of operations.
 
RISK RELATING TO INTERNATIONAL OPERATIONS
 
    In the event the Company is successful in developing its products,
manufacturing them in commercial quantities and receiving necessary FDA and
foreign regulatory registrations or approvals, the Company plans to market its
products in international markets, either on its own or with its strategic
partners. The Company has limited experience in marketing its products overseas.
Changes in overseas economic conditions, currency exchange rates, foreign tax
laws or tariffs or other trade regulations could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
                                       13
<PAGE>
The anticipated international nature of the Company's business is also expected
to subject it and its representatives, agents and distributors to laws and
regulations of the foreign jurisdictions in which they operate or in which the
Company's products under development are sold. The regulation of medical devices
in a number of such jurisdictions, particularly in the European Union, continues
to develop and there can be no assurance that new laws or regulations will not
have an adverse effect on the Company's business, financial condition and
results of operations. In addition, the laws of certain foreign countries do not
protect the Company's intellectual property rights to the same extent as do the
laws of the United States. See "Business -- Government Regulation" and "Business
- -- Patents and Proprietary Rights."
 
PRODUCT LIABILITY RISK; LIMITED INSURANCE COVERAGE
 
    The Company faces an inherent and significant business risk of exposure to
product liability claims in the event that the use of its products results in
personal injury or death and there can be no assurance that the Company will not
experience any material product liability losses in the future. Also, in the
event that any of the Company's products prove to be defective, the Company may
be required to recall or redesign such products. The Company's current product
liability insurance coverage limit is $4.0 million in the aggregate. There can
be no assurance that such coverage limits are adequate to protect the Company
from any liabilities it might incur in connection with the development,
manufacture and sale of its products. In addition, the Company may require
increased product liability coverage if any products are used in clinical
evaluations or successfully commercialized. Product liability insurance is
expensive and in the future may not be available to the Company on acceptable
terms, if at all. A successful product liability claim or series of claims
brought against the Company in excess of its insurance coverage or a product
recall could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
UNCERTAINTY REGARDING PATENTS AND PROTECTION OF PROPRIETARY TECHNOLOGY; RISKS OF
  FUTURE LITIGATION
 
    Vista Medical relies on a combination of technical leadership, patent, trade
secret, copyright and trademark protection and nondisclosure agreements to
protect its proprietary rights. As of February 28, 1997, the Company had
exclusive rights to 11 issued United States patents, 12 pending United States
patent applications, three issued foreign patents and 17 pending foreign
applications covering various aspects of its devices and systems. The Company
intends to file additional patent applications in the future. The failure of
such patents to issue could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The Company's future success will depend, in part, on its ability to
continue to develop patentable products, enforce its patents and obtain patent
protection for its products both in the United States and in other countries.
The patent positions of medical device companies, including the Company,
however, are generally uncertain and involve complex legal and factual
questions. There can be no assurance that patents will issue from any patent
applications owned by or licensed to the Company or that, if patents do issue,
the claims allowed will be sufficiently broad to protect the Company's
technology. In addition, there can be no assurance that any issued patents owned
by or licensed to the Company will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company.
 
    The medical device industry has been characterized by extensive litigation
regarding patents and other intellectual property rights. Litigation, which
would result in substantial expense to the Company, may be necessary to enforce
any patents issued or licensed to the Company and/or to determine the scope and
validity of proprietary rights of third parties or whether the Company's
products, processes or procedures infringe any such third-party proprietary
rights. The Company may also have to participate in interference proceedings
declared by the United States Patent and Trademark Office, which could result
 
                                       14
<PAGE>
in substantial expense to the Company, to determine the priority of inventions
covered by the Company's issued United States patents or pending patent
applications. Furthermore, the Company may have to participate at substantial
cost in International Trade Commission proceedings to enjoin importation of
products which would compete unfairly with products of the Company. Any adverse
outcome of any patent litigation (including interference proceedings) could
subject the Company to significant liabilities to third parties, require
disputed rights to be licensed from or to third parties or require the Company
to cease using the technology in dispute.
 
    Patent applications in the United States are maintained in secrecy until a
patent issues, and patent applications in foreign countries are maintained in
secrecy for a period of time after filing. After such period of time, and
usually before the grant of the patent, patent applications in foreign countries
are published. While publication of discoveries in the scientific or patent
literature tends to lag behind actual discoveries and the filing of related
patent applications, such publication may enable the Company's competitors to
ascertain what areas of research or development the Company is engaged in prior
to the Company's receipt of patent protection in the United States or foreign
countries relating to such research or development.
 
    In general, the development of visualization and information systems and
related surgical instruments and accessories is intensely competitive. Patents
issued and patent applications filed relating to medical devices are numerous
and there can be no assurance that current and potential competitors and other
third parties have not filed or in the future will not file applications for, or
have not received or in the future will not receive, patents or obtain
additional proprietary rights relating to products or processes used or proposed
to be used by the Company. There can also be no assurance that third parties
will not assert infringement claims against the Company in the future or that
any such assertions will not result in costly litigation or require the Company
to obtain a license to intellectual property rights of such parties. There can
be no assurance that any such licenses would be available on terms acceptable to
the Company, if at all. Furthermore, parties making such claims may be able to
obtain injunctive or other equitable relief that could effectively block the
Company's ability to make, use, sell or otherwise practice its intellectual
property (whether or not patented or described in pending patent applications),
or to further develop or commercialize its products in the United States and
abroad and could result in the award of substantial damages. Defense of any
lawsuit or failure to obtain any such license could have a material adverse
effect on the Company.
 
    The Company relies on unpatented trade secrets to protect its proprietary
technology, and no assurance can be given that others will not independently
develop or otherwise acquire the same or substantially equivalent technologies
or otherwise gain access to the Company's proprietary technology or disclose
such technology or that the Company can ultimately protect its rights to such
unpatented proprietary technology. No assurance can be given that third parties
will not obtain patent rights to such unpatented trade secrets, which patent
rights could be used to assert infringement claims against the Company. The
Company also relies on confidentiality agreements with its collaborators,
employees, advisors, vendors and consultants to protect its proprietary
technology. There can be no assurance that these agreements will not be
breached, that the Company would have adequate remedies for any breach or that
the Company's trade secrets will not otherwise become known or be independently
developed by competitors. In addition, the Company's agreements with its
employees and consultants require disclosure to the Company of ideas,
developments, discoveries or inventions conceived during employment or
consulting, as the case may be, and assignment to the Company of proprietary
rights to such matters related to the business and technology of the Company.
The extent to which efforts by others will result in patents and the effect on
the Company of the issuance of such patents is unknown. Failure to obtain or
maintain patent and trade secret protection, for any reason, could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Patents and Proprietary Rights" and
"Business -- Competition."
 
                                       15
<PAGE>
    The Company has in-licensed certain aspects of its technology. In September
1995, Mr. H. McKinley and McKinley Optics, Inc. (collectively, "McKinley")
granted to the Company a perpetual, exclusive, worldwide license to make, have
made, modify, use, lease, market, sell and otherwise distribute certain
endoscopes and other medical products incorporating a stereo objective lens
and/or a relay lens configuration for medical purposes. Under the terms of this
license agreement, Vista Medical is obligated to pay McKinley an annual
maintenance royalty, additional royalties upon the sale of certain numbers of
systems incorporating the McKinley technology and royalties on net sales of
products incorporating the McKinley technology. The exclusive license granted
under this agreement becomes a non-exclusive license in the event Vista Medical
fails to pay any royalties following receipt of notice of such failure to pay.
In addition, Vista Medical has the right to terminate the agreement with limited
notice.
 
    In June 1996, Fuji Film Co. and Fuji Photo Optical Co., Ltd. (collectively,
"Fuji") granted to the Company a non-exclusive license to certain optical zoom
technology for use in endoscopes. Vista Medical is obligated to pay royalties on
net sales of products in the United States which incorporate Fuji's technology.
Fuji may terminate the agreement if Vista Medical does not cure any violation of
the agreement within a limited period of time. Failure of the Company to retain
rights to these technologies could have a material, adverse effect on the
Company's business, financial condition and results of operations. See "Business
- -- Patents and Proprietary Rights."
 
DEPENDENCE ON KEY PERSONNEL AND ADVISORS
 
    The Company's future business and operating results depend in significant
part upon the continued contributions of its key technical and senior management
personnel, many of whom would be difficult to replace and certain of whom
perform important functions for the Company beyond those functions suggested by
their respective job titles or descriptions. The Company's business and future
operating results also depend in significant part upon its ability to attract
and retain qualified management, manufacturing, technical, marketing and sales
and support personnel for its operations. Competition for such personnel is
intense, and there can be no assurance that the Company will be successful in
attracting or retaining such personnel. The loss of any key employee, the
failure of any key employee to perform in his or her current position or the
Company's inability to attract and retain skilled employees, as needed, could
materially adversely affect the Company's business, financial condition and
results of operations. See "Management -- Executive Officers and Directors."
 
    The Company has established two Clinical Advisory Boards made up of leading
surgeons, one focused on minimally invasive cardiac surgery, the other focused
on a number of HNS microsurgery and other specialties. Members of the Clinical
Advisory Boards consult with the Company exclusively in the field of
visualization, but are free to consult with other instrumentation companies and
are employed elsewhere on a full-time basis. As a result, they only spend a
limited amount of time on the Company's affairs. Although the Company has
entered into consulting agreements, with terms ranging from 12 months to two
years, including confidentiality provisions with each of the members of the
Clinical Advisory Boards, there can be no assurance that the consulting and
confidentiality agreements between the Company and each of the members of the
Clinical Advisory Boards will not be terminated or breached. In addition, there
can be no assurance that any of such agreements will be renewed upon
termination. See "Business -- Clinical Advisory Boards."
 
NEED TO MANAGE A CHANGING BUSINESS
 
    In order to compete effectively against current and future competitors,
prepare additional products for potential commercialization and develop future
products, the Company, believes that it must continue to expand its operations,
particularly in the areas of development and manufacturing. If the Company were
to experience significant growth in the future, such growth would likely result
in new and increased responsibilities for management personnel and place
significant strain upon the Company's management, operating and financial
systems and resources. To accommodate such growth and compete effectively, the
Company must continue to implement and improve information systems,
 
                                       16
<PAGE>
procedures and controls, and to expand, train, motivate and manage its work
force. The Company is in the process of implementing an integrated financial,
manufacturing and inventory information system. Implementing such a system can
be time-consuming and expensive and requires significant management resources.
There can be no assurance that such system will be implemented on a timely
basis. All of the foregoing demands will require the addition of new management
personnel. The Company's future success will depend to a significant extent on
the ability of its current and future management personnel to operate
effectively, both independently and as a group. There can be no assurance that
the Company's personnel, systems, procedures and controls will be adequate to
support the Company's future operations. Any failure to implement and improve
the Company's operational, financial and management systems or to expand, train,
motivate or manage employees could have a material adverse effect on the
Company's business, financial condition and results of operations. See "Business
- -- Human Resources" and "Management."
 
NO PRIOR TRADING MARKET FOR COMMON STOCK; POTENTIAL VOLATILITY OF STOCK PRICE
 
    Prior to this Offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will develop
or be sustained after this Offering. The initial public offering price will be
determined through negotiations among the Company and the representatives of the
Underwriters based on several factors and may not be indicative of the market
price of the Common Stock after this Offering. The market price of the shares of
Common Stock is likely to be highly volatile and may be significantly affected
by factors such as actual or anticipated fluctuations in the Company's operating
results, changes in financial estimates by securities analysts, announcements of
technological innovations, new products or new contracts by the Company or its
competitors, regulatory announcements, developments with respect to patents or
proprietary rights, conditions and trends in the medical device and other
technology industries, adoption of new accounting standards affecting the
medical device industry, general market conditions and other factors. In
addition, the stock market has from time to time experienced significant price
and volume fluctuations that have particularly affected the market prices for
shares of early stage companies. These broad market fluctuations may adversely
affect the market price of the Common Stock. In the past, following periods of
volatility in the market price of a particular company's securities, securities
class action litigation has often been brought against that company. Such
litigation, if brought against the Company, could result in substantial costs
and a diversion of management's attention and resources. See "Underwriting."
 
CONTROL BY EXISTING STOCKHOLDERS, OFFICERS AND DIRECTORS
 
    Upon completion of this Offering, the present directors, executive officers
and principal stockholders of the Company and their affiliates will beneficially
own approximately 71.2% of the outstanding Common Stock. As a result, these
stockholders will be able to exercise control over all matters requiring
stockholder approval (including the election of directors and approval of
significant corporate transactions) irrespective of how other stockholders may
vote. Such concentration of ownership may have the effect of delaying or
preventing a change in control of the Company and thereby adversely affect the
market price of the Common Stock. See "Principal Stockholders."
 
SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
    Sales of a substantial number of shares of Common Stock in the public market
following this Offering could adversely affect the market price for the Common
Stock. The number of shares of Common Stock available for sale in the public
market is limited by restrictions under the Securities Act of 1933, as amended
(the "Securities Act"), and by lock-up agreements under which the Company's
officers, directors and certain stockholders of the Company (who hold an
aggregate of approximately 9,171,000 shares of Common Stock upon the completion
of this Offering, including shares issued or issuable upon the exercise of
vested options and warrants outstanding as of February 28, 1997) have agreed not
to sell or otherwise dispose of any of their shares for a period of 180 days
after the date of this
 
                                       17
<PAGE>
Prospectus without the prior written consent of Goldman, Sachs & Co. Goldman,
Sachs & Co. may, in its sole discretion and at any time without notice, release
all or any portion of the securities subject to lock-up agreements. As a result
of restrictions under the Securities Act and the lock-up agreements, the
following shares of Common Stock (including shares issued or issuable upon the
exercise of vested options and warrants outstanding as of February 28, 1997)
will be eligible for future sale: on the date of this Prospectus, 3,500,750
shares (including the 3,500,000 shares offered hereby) will be eligible for
sale; an additional approximately 7,571,000 shares will be eligible for sale 180
days after the date of this Prospectus; the remaining 1,600,000 shares of Common
Stock will become eligible for sale under Rule 144 at various dates thereafter
as the holding period provisions of Rule 144 are satisfied. In addition, the
Company intends to register on the effective date of this Offering a total of
2,820,000 shares of Common Stock subject to outstanding options or reserved for
issuance under the Company's 1997 Stock Option/Stock Issuance Plan and 200,000
shares of Common Stock reserved for issuance under its 1997 Employee Stock
Purchase Plan. Further, upon expiration of such lock-up agreements, holders of
approximately 8,780,679 shares of Common Stock will be entitled to certain
registration rights with respect to such shares. If such holders, by exercising
their registration rights, cause a large number of shares to be registered and
sold in the public market, such sales could have a material adverse effect on
the market price for the Common Stock.
 
    The Company cannot predict the effect, if any, that market sales of shares
or the availability of shares for sale will have on the market price of the
Common Stock prevailing from time to time. Sales of significant amounts of the
Common Stock in the public market could adversely affect the market price of the
Common Stock and could impair the Company's ability to raise capital through an
offering of its equity securities. See "Description of Capital Stock --
Registration Rights" and "Shares Eligible for Future Sale."
 
HAZARDOUS MATERIALS
 
    The Company's research and development may involve the controlled use of
hazardous materials and chemicals. Although the Company believes that its safety
procedures for handling and disposing of such materials comply with the
standards prescribed by state and federal regulations, the risk of accidental
contamination or injury from these materials cannot be completely eliminated. In
the event of such an accident, the Company could be held liable for any
resultant damages, and any such liability could exceed the resources of the
Company. The Company may incur substantial cost to comply with environmental
regulations.
 
NO DIVIDENDS
 
    The Company currently intends to retain any future earnings for use in its
business and does not anticipate paying any cash dividends in the future. See
"Dividend Policy."
 
EFFECT OF CERTAIN CHARTER PROVISIONS; ANTITAKEOVER EFFECTS OF SECOND RESTATED
CERTIFICATE OF   INCORPORATION, BYLAWS AND DELAWARE LAW
 
    Upon completion of this Offering, the Company's Board of Directors will have
the authority to issue up to 5,000,000 shares of preferred stock and to
determine the price, rights, preferences, privileges and restrictions, including
voting and conversion rights of such shares, without any further vote or action
by the Company's stockholders. The rights of the holders of Common Stock will be
subject to, and may be adversely affected by, the rights of the holders of any
preferred stock that may be issued in the future. The issuance of preferred
stock could have the effect of making it more difficult for a third party to
acquire a majority of the outstanding voting stock of the Company.
 
    In addition, the Company's Second Restated Certificate of Incorporation
provides for a classified Board of Directors such that approximately one-third
of the members of the Company's Board of
 
                                       18
<PAGE>
Directors are elected at each annual meeting of stockholders. Such
classification of the Company's Board of Directors may have the effect of
delaying, deferring or discouraging changes in control of the Company.
 
    Making more difficult or discouraging a change in control of the Company may
adversely affect the market price of the Common Stock. See "Description of
Capital Stock -- Preferred Stock" and "Description of Capital Stock -- Possible
Antitakeover Effect of Certain Charter Provisions."
 
SUBSTANTIAL DILUTION
 
    Investors participating in this Offering will incur immediate, substantial
dilution. To the extent outstanding options to purchase the Common Stock are
exercised, there will be further dilution. If the net proceeds of this Offering,
together with available funds and cash generated from operations, are
insufficient to satisfy the Company's cash needs, the Company may be required to
sell additional equity or convertible debt securities. The sale of additional
equity or convertible debt securities could result in additional dilution to the
Company's stockholders. See "Dilution" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources."

                                  THE COMPANY
 
    Vista Medical Technologies, Inc. ("Vista Medical" or the "Company")
develops, manufactures and intends to market proprietary visualization and
information systems that enable minimally invasive surgical solutions in
cardiothoracic, head, neck and spine ("HNS") and other selected microsurgical
procedures. The Company currently markets three-chip cameras for endoscopy and
related surgical instruments and accessories. Vista Medical's visualization and
information systems bring together head-mounted display ("HMD") technology
originally developed for applications in military aerospace by Kaiser Aerospace
and Electronics Corporation ("Kaiser Aerospace") and three-dimensional ("3-D")
imaging capability from its acquisition of Oktas, Inc.
 
    The development and subsequent widespread adoption of minimally invasive
surgical approaches have revolutionized many surgical fields, including general
surgery, orthopedics, gynecology and urology. Minimally invasive surgical
procedures are performed through strategically placed ports or mini-incisions in
a patient's body, thereby avoiding the larger incisions used in traditional open
surgery. Minimally invasive procedures are designed to decrease complications,
reduce pain and suffering, speed recovery and decrease costs associated with
many aspects of patient care. This movement toward minimally invasive surgery
has been driven by advances in both device technology and surgical technique.
Minimally invasive microsurgery ("MIM") is an extension of minimally invasive
surgery and is characterized by greater complexity and precision. MIM procedures
have been made possible primarily by recent advances in medical technology.
 
    The application of minimally invasive techniques to cardiothoracic surgery
is commonly regarded as a revolutionary development in modern surgery. Minimally
invasive cardiac procedures avoid the trauma caused by sternotomy and promise to
significantly decrease pain and trauma and shorten recovery times.
Cardiothoracic MIM requires the surgeon to perform technically challenging
procedures, including working on tiny delicate structures (such as a one
millimeter heart vessel) with highly restricted access through small incisions.
 
    The Company believes that an advanced visualization technology which
provides the surgeon with an intuitive and ergonomic solution to the inherent
vision restrictions of the MIM approach will enable the use of the MIM technique
with increased safety, efficacy and precision. In order to meet this
visualization challenge, the Company has developed proprietary visualization and
information systems.
 
    Vista Medical's proprietary technology is based on the following principles
which the Company believes are essential in advancing the techniques of MIM: (i)
three-dimensional view; (ii) high resolution images; (iii) improved access
through miniaturization technology; (iv) optimized surgical ergonomics; and (v)
integration of anatomical image with critical monitoring and diagnostic
information.
 
    Based on these principles, Vista Medical develops visualization products and
related information systems that are customized for the specific cardiothoracic
and HNS procedures to which they are directed. The Company's product lines
include the Series 8000 Advanced Visualization and Information System ("Series
8000"), designed for use in cardiothoracic procedures, and StereoSite, designed
for use in microscopic and endoscopic procedures in HNS. The Company also offers
surgical instruments and accessories designed for use in both cardiothoracic and
HNS MIM procedures.

BUSINESS STRATEGY
 
    The Company's business strategy is to become the leading developer and
marketer of advanced visualization and information systems for MIM applications
in cardiothoracic, HNS and other selected surgical specialties. Key elements of
the Company's strategy include:
 
    - Establish advanced visualization technologies as standard practice in
      minimally invasive cardiac surgery.
 
    - Promote Vista Medical's visualization solution for use in all types of
      cardiac surgery.
 
    - Develop MIM applications through specialty-focused business units by
      leveraging the Company's technology platform.
 
    - Accelerate adoption of the Series 8000 Advanced Visualization and
      Information System in the cardiac market by implementing a per-procedure
      pricing strategy.
 
    - Increase the surgeon's real-time access to critical data.
 
    - Enter into strategic relationships which complement Company resources.
 
    To assist in implementing its business strategy, the Company has established
two Clinical Advisory Boards made up of leading surgeons, one focused on
minimally invasive cardiac surgery, the other focused on HNS microsurgery and a
number of other specialties. Members of the Clinical Advisory Boards consult
with the Company exclusively in the field of visualization. The Clinical
Advisory Boards are intended to act as a clinical reference for the Company and
to provide access to potential training sites for the Company's visualization
products.
 
RECENT DEVELOPMENTS
 
    In November 1996, Vista Medical and Medtronic, Inc. ("Medtronic"), a leading
cardiac company, entered into a strategic alliance providing for the
distribution and co-promotion of the Company's current and future visualization
and information systems for cardiac surgery, including the Series 8000 (the
"Vista Systems"). Medtronic will act as Vista Medical's exclusive distributor
for the Vista Systems for use in cardiothoracic surgical procedures in Europe,
the Middle East (excluding Afghanistan and Pakistan) and Africa and will
co-promote the Vista Systems in North America. Vista Medical retains direct
distribution rights in North America as well as the worldwide right to
distribute its systems for use in all other procedures. In conjunction with
entering into the agreement, Medtronic made a $10.0 million equity investment in
the Company.
 
    The Company believes that the control and processing of information is a key
component in the development of advanced visualization systems. As a result, in
January 1997, the Company obtained from GDE Systems, Inc. ("GDE"), a leading
military electronics and information management company, an exclusive worldwide
license to software and documentation and trademarks of GDE for use in the
medical field. Since 1993, GDE's subsidiary, Healthcom, has been adapting the
software licensed to Vista Medical to provide high-speed, image-based
information processing and networking capabilities specifically for medical
applications. In connection with the license, Vista Medical will issue to GDE
Common Stock with a value (based on the initial public offering price) of
$250,000.
 
    In February 1997, the Company entered into an agreement with Heartport, Inc.
("Heartport"), a leading company developing minimally invasive technology for
heart surgery. Vista Medical will sell four Series 8000 systems to Heartport,
for use in the Heartport Research and Training Center in Salt Lake City, Utah.
Heartport has agreed to use the Series 8000 in its training centers, to promote
that its training courses utilize the Series 8000 and to endorse the Series 8000
as the preferred 3-D video visualization and information solution for minimally
invasive heart surgery. In connection with the agreement, the
 
                                       21
<PAGE>
Company issued to Heartport a warrant to purchase up to 100,000 shares of Common
Stock, exercisable at any time after this Offering and prior to March 31, 2001,
at a price per share equal to the initial public offering price.
 
    The Company believes that all of its products or products under development
are, or will be, eligible for 510(k) clearance to market by the United States
Food and Drug Administration ("FDA"). Applications for 510(k) clearance to
market have been filed or clearance to market has been received for all
components which are necessary for initial Series 8000 commercialization. The
Company believes that there are predicate devices which can be relied upon for
its products for which regulatory applications are in process. A majority of
these predicate devices were developed by the Company or its strategic partners.
 
    The Company was incorporated in the State of California in July 1993 and
reincorporated in the State of Delaware in November 1996. Unless the context
indicates otherwise, the "Company" or "Vista Medical" refers to Vista Medical
Technologies, Inc. The Company's principal executive offices are located at 5451
Avenida Encinas, Suite A, Carlsbad, California 92008, and its telephone number
is (619) 603-9120.
 
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 3,500,000 shares of
Common Stock offered hereby are estimated to be approximately $38,360,000
($44,219,000 if the Underwriters' over-allotment option is exercised in full),
assuming a public offering price of $12.00 per share (the mid-point of the range
set forth on the front cover) and after deducting the estimated underwriting
discounts and commissions and other estimated offering expenses.
 
    The Company intends to use the net proceeds of this Offering, including the
interest thereon, to fund product introductions (approximately 33%), sales and
marketing activities (approximately 20%), research and development
(approximately 14%), the acquisition of capital equipment for manufacturing
scale-up (approximately 9%) and for working capital and general corporate
purposes (approximately 24%). The Company may also use a portion of the net
proceeds for the acquisition of products and technologies complementary to those
of the Company. There are no present arrangements or agreements for any such
acquisitions.
 
    The amounts actually expended for each purpose may vary significantly
depending upon numerous factors, including the progress of the Company's product
development, the regulatory status of such products, the timing of regulatory
approvals, technological advances, the commercial potential of the Company's
products and the status of competitive products. In addition, expenditures will
also depend upon the establishment of collaborative research agreements with
other companies, the availability of additional financing and other factors. The
Company believes that its existing cash, cash equivalents and short-term
investments, combined with the net proceeds of this Offering, its committed
future contract revenue, projected funding from equipment leases and interest
income, will be adequate to satisfy its capital requirements and fund operations
for the current and foreseeable future. Pending application of the net proceeds
as described above, the Company intends to invest the net proceeds of this
Offering in short-term investment-grade securities.
 
                                DIVIDEND POLICY
 
    The Company has never declared or paid dividends on its capital stock. The
Company does not anticipate paying any cash dividends in the foreseeable future.
Payments of future dividends, if any, will be at the discretion of the Company's
Board of Directors after taking into account various factors, including the
Company's financial condition, operating results, current and anticipated cash
needs and plans for expansion. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."

                                    DILUTION
 
    The net tangible book value of the Company at December 31, 1996 was
$12,637,710, or $1.37 per share (after giving effect to the conversion of all
outstanding shares of Preferred Stock into Common Stock upon the consummation of
this Offering). Net tangible book value per share of Common Stock represents the
amount of total tangible assets of the Company less total liabilities divided by
the number of shares of the Common Stock outstanding. After giving effect to the
sale of the 3,500,000 shares of Common Stock offered hereby at an assumed public
offering price of $12.00 per share, and after deducting underwriting discounts
and commissions and estimated offering expenses payable by the Company, the
Company's net tangible book value as of December 31, 1996 would have been
$50,997,710 or $4.01 per share of Common Stock. This represents an immediate
increase in net tangible book value per share of Common Stock of $2.64 to
existing stockholders and immediate dilution in net tangible book value of $7.99
per share to new investors purchasing Common Stock in this Offering. The
following table illustrates the per share dilution:

    All of the above computations assume no exercise of outstanding options or
warrants to purchase Common Stock. As of December 31, 1996, options to purchase
1,245,801 shares of Common Stock were outstanding at a weighted average exercise
price of approximately $0.32 per share under the Company's stock option plan. To
the extent these options become vested and are exercised, there will be further
dilution to new investors. Since December 31, 1996, the Company has (i) issued
options to purchase 112,500 shares of Common Stock at a weighted average
exercise price of $2.93 per share, (ii) issued 75,625 shares of Common Stock
upon the exercise of options at a weighted average price of $0.46 per share,
(iii) issued warrants to purchase 100,000 shares of Common Stock at a weighted
average price equal to the initial public offering price of the Common Stock
offered hereby and (iv) agreed to issue to GDE immediately following the closing
of this Offering a number of shares of Common Stock equal to $250,000 divided by
the initial public offering price of the Common Stock offered hereby. As of
February 28, 1997, the Company also had an additional 1,537,324 shares of Common
Stock available for grant pursuant to the Company's stock option plan. Further
dilution may result from the exercise of such outstanding options. See
"Management -- Benefit Plans."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following should be read in conjunction with "Selected Financial Data"
and the Company's Financial Statements and Notes thereto appearing elsewhere in
this Prospectus.
 
OVERVIEW
 
    The Company develops, manufactures and intends to market proprietary
visualization and information systems that enable minimally invasive surgical
solutions in cardiothoracic, head, neck and spine ("HNS") and other selected
microsurgical procedures. The Company currently markets three-chip cameras for
endoscopy and related surgical instruments and accessories.
 
    The Company has generated minimal revenues from the sale of products and has
been unprofitable since its formation in July 1993. For the period from the
Company's formation to December 31, 1996, the Company has incurred cumulative
net losses of approximately $13.6 million. The Company expects to continue to
incur substantial losses for at least the next 18 months. There can be no
assurance that the Company's development efforts will result in commercially
available products, that the Company will be successful in introducing its
products under development, or that the required regulatory approval of products
will be obtained in a timely manner, if ever.
 
    The Company has increased its staffing each year to support its research and
development, manufacturing and sales and marketing activities. At December 31,
1994, 1995 and 1996, the Company had 11, 21 and 49 employees, respectively. The
Company expects to continue to increase staffing levels significantly in future
periods in support of its research and development, manufacturing scale up,
service and support, sales and marketing and general and administrative
activities related to new products. The Company expects that its increased
staffing needs will negatively impact operating income, which in turn may impact
the Company's ability to achieve profitability.
 
    The Company recorded noncash deferred compensation of approximately $2.5
million in connection with the grant of certain stock options during 1996, of
which approximately $447,000 was recognized as an expense in 1996. The Company
will record an additional $743,000 of deferred compensation for stock options
granted in January and February 1997. The unamortized balance of the deferred
compensation will be expensed over the vesting periods of the options (typically
four or five years) and, therefore, will continue to impact the Company's
operating results through 2001.
 
    This discussion contains forward-looking statements that involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed in "Risk
Factors."
 
RESULTS OF OPERATIONS
 
  SALES
 
    The Company had revenues from product sales of $59,000, $1,719,000 and
$2,244,000 for the years ended December 31, 1994, 1995 and 1996, respectively.
The increase in revenues from 1994 to 1995 was primarily attributable to the
introduction of three-chip cameras by the Company. The increase in revenue from
1995 to 1996 was attributable to the increased sales of the Company's three-chip
cameras and the sale of surgical instruments and sutures for which the Company
acquired distribution rights during 1996. Sales to individual customers
exceeding 10% or more of revenues for the years ended December 31, 1994, 1995
and 1996 were as follows: during 1994, two customers accounted for 82% and 18%
of revenues; during 1995, one customer accounted for 85% of revenues; during
1996, three customers accounted for 30%, 27% and 25% of revenues. The Company
believes that the loss of any of these customers would not have a material
adverse effect on the Company's business, operating
 
                                       26
<PAGE>
results or financial condition and that concentration of revenues to individual
customers will likely decrease in future periods as the Company introduces new
products.
 
  COSTS AND EXPENSES
 
    COST OF SALES.  Cost of sales consist primarily of purchased parts and
supplies, labor, facilities-related expenses and equipment depreciation. The
Company's cost of sales were $43,000, $1,272,000 and $2,253,000 for the years
ended December 31, 1994, 1995 and 1996, respectively. The increase in cost of
sales from 1994 to 1995 was related to the growth in revenue from 1994 to 1995.
The increase in cost of sales from 1995 to 1996 was attributable to the increase
in revenues from 1995 to 1996 as well as the investment the Company made in its
manufacturing infrastructure to accommodate the scale-up for new product
introductions. This investment includes personnel expenses, consulting fees and
facilities-related costs and was approximately $208,000. The Company anticipates
it will continue to make significant investments in manufacturing infrastructure
in 1997 and 1998 and expects this investment to increase cost of sales during
such time period.
 
    RESEARCH AND DEVELOPMENT EXPENSE.  Research and development expense consists
primarily of personnel expenses, fees paid to independent contractors, certain
purchased technology and development, and equipment and facilities costs to
support product development, prototyping and product evaluation. The Company's
research and development expenses were $1,328,000, $1,904,000 and $3,880,000 for
the years ended December 31, 1994, 1995 and 1996, respectively. The increase in
research and development expenses from 1994 to 1995 was primarily attributable
to increased staffing and purchased research and development expense. The
increase in research and development expenses from 1995 to 1996 was attributable
to significant increases in staffing, purchased research and development
expense, and consulting fees related to development, prototyping and evaluation
of future products. The Company anticipates it will continue to devote
substantial resources to research and development and that research and
development expenses, particularly the costs associated with increased staffing,
prototyping and product evaluation will increase substantially in 1997 and
beyond.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses consist
primarily of the cost of sales and marketing personnel and independent
contractors, commissions, office facilities, travel and promotional events such
as trade shows, seminars and technical conferences, as well as the costs
associated with marketing programs necessary to support the expansion of the
Company's business. Sales and marketing expenses increased from approximately
$291,000 in 1994 to $834,000 in 1995 and to approximately $2,057,000 in 1996.
The increase from 1994 to 1995 was primarily attributable to increased staffing
and consulting fees related to the introduction of new products and expansion of
the Company's product line. The increase from 1995 to 1996 was related to
significant increases in staffing and related expenses, commissions and
professional and consulting fees as the Company continued to build its sales
operations and expand its marketing activities in relation to future products.
The Company believes that its sales and marketing expenses will increase
substantially in 1997 and 1998 as it continues to build its sales force and
expand its marketing efforts in connection with commercialization of new
products.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
consist primarily of salaries and other related expenses of the administrative
and executive, finance and accounting, and information systems departments of
the Company and expenses associated with legal and accounting requirements.
General and administrative expenses were $758,000, $1,034,000 and $3,103,000 for
the years ended December 31, 1994, 1995 and 1996, respectively. The increase
from 1994 to 1995 was primarily attributable to increased staffing and related
costs associated with the growth of the Company's business during this period.
The increase from 1995 to 1996 was primarily attributable to the continued
development of corporate management and related support functions, the addition
of new facilities and expansion of current facilities, expansion of the
Company's information systems and the
 
                                       27
<PAGE>
amortization of deferred compensation. The Company recorded noncash deferred
compensation of approximately $2.5 million in connection with the grant of
certain stock options during 1996, of which approximately $447,000 was
recognized as an expense in 1996. The Company will record an additional $743,000
of deferred compensation for stock options granted in January and February 1997.
The unamortized balance of the deferred compensation will be expensed over the
vesting periods of the options (typically four or five years) and, therefore,
will continue to impact the Company's operating results through 2001. The
Company also expects that its general and administrative expenses will increase
in the future as it expands its staffing, information systems and other related
infrastructure and as a result of increases in expenses associated with being a
public company.
 
  OTHER INCOME
 
    LICENSE INCOME.  License income of $1,493,000 in 1996 represents the net
amount received by the Company from a perpetual license to certain of its
technology and patents. Prior to 1996, the Company had no license income.
 
    INTEREST INCOME.  Interest income represents the net amount of interest
earned by the Company on its cash and short-term investments and interest
expense on debt. Interest income increased from approximately $51,000 for the
year ended December 31, 1995 to approximately $117,000 for the year ended
December 31, 1996 due primarily to increasing average investment balances. The
Company had immaterial amounts of interest income prior to 1995.
 
  TAXES
 
    At December 31, 1996, the Company had federal and state tax net loss
carryforwards of approximately $8,494,000 and $5,146,000, respectively. The
federal and state tax loss carryforwards will expire in 2010 and 2000,
respectively, unless previously utilized. At December 31, 1996, the Company also
had federal and state research tax credit carryforwards of approximately
$135,000 and $143,000, respectively, which will expire in 2010 unless previously
utilized. The Company has provided a full valuation allowance on the deferred
tax assets as realization of such assets is uncertain.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At December 31, 1996, the Company had approximately $10,285,000 in cash,
cash equivalents and short-term investments. Since formation, the Company has
financed its operations and investments in equipment and inventories through
advances from a related party totaling $5,379,000, net proceeds from licensing
of certain of the Company's technology for $1,000,000 and from the private sale
of common and preferred stock totaling approximately $23,019,000, of which
$3,004,000 was used to repay advances from a related party.
 
    Net cash used in operating activities was approximately $2,288,000,
$3,567,000 and $6,937,000 for 1994, 1995 and 1996, respectively. The increase in
net cash used from operating activities each year has resulted primarily from
increasing net losses during such periods and investments in inventories
associated with expansion of the Company's product line, partially offset by
increases in accounts payable and accrued expenses.
 
    Net cash used in investing activities was approximately $94,000, $298,000
and $1,239,000 for 1994, 1995 and 1996, respectively. The increase in net cash
used in investing activities each year has resulted primarily from the purchase
of short-term investments and the purchase of property and equipment related to
increased staffing, expansion of manufacturing capabilities and marketing
demonstrations.
 
    Cash flows from financing activities in 1994, 1995 and 1996 were $1,950,000,
$7,090,000 and $15,061,000, respectively. The increase in cash flows from
financing activities resulted primarily from
 
                                       28
<PAGE>
increased advances from a related party in 1994 and primarily from the private
sale of common and preferred stock in 1995 and 1996.
 
    Capital expenditures for equipment to support the Company's expanded
operations were approximately $57,000, $81,000 and $1,221,000 for 1994, 1995 and
1996, respectively. The Company expects its capital expenditures to continue to
grow as it expands its manufacturing base and scope of operations in future
periods. At December 31, 1996, the Company had commitments for capital
expenditures totaling $1,109,000 relating primarily to custom injection molded
tooling required for certain of the Company's products and for prototype systems
to be used for evaluation and demonstration purposes.
 
    The Company expects it will continue to incur substantial expense in
additional research and development activities, production scale up, continued
establishment of its sales force and marketing organization and administrative
support activities. The Company anticipates that the net proceeds from this
Offering and the interest income thereon, together with its existing cash, cash
equivalents and short-term investments will be sufficient to fund operations for
the current and foreseeable future. Certain circumstances, however, including
delayed regulatory approvals, slow rate of market acceptance of the Company's
products and the Company's inability to scale up manufacturing, would accelerate
the Company's use of proceeds from the Offering. Therefore the Company may
require additional funds to support its operating requirements or for other
purposes. Accordingly, the Company may, from time to time, seek to raise such
additional funds through public or private equity financings or from other
sources. There can be no assurance that additional financing will be available
at all or that, if available, such financing would be obtainable on terms
acceptable to the Company.

OVERVIEW
 
    Vista Medical develops, manufactures and intends to market proprietary
visualization and information systems that enable minimally invasive surgical
solutions in cardiothoracic, head, neck and spine and other selected
microsurgical procedures. The Company currently markets three-chip cameras for
endoscopy and related surgical instruments and accessories. Vista Medical's
visualization and information systems bring together head-mounted display
technology originally developed for applications in military aerospace by Kaiser
Aerospace and Electronics Corporation ("Kaiser Aerospace") and three-dimensional
imaging capability from its acquisition of Oktas, Inc.
 
BACKGROUND
 
  MINIMALLY INVASIVE SURGERY
 
    The development and subsequent widespread adoption of minimally invasive
surgical approaches have revolutionized many surgical fields, including general
surgery, orthopedics, gynecology and urology. Minimally invasive surgical
procedures are performed through strategically placed ports or mini-incisions in
a patient's body thereby avoiding the larger incisions used in traditional open
surgery. A minimally invasive approach is most advantageous in cases in which
significant trauma results from gaining surgical access to an affected organ or
site. Notable examples of minimally invasive surgical procedures include
laparoscopic procedures in the field of general surgery and arthroscopic
procedures in the field of orthopedic surgery, many of which have become the
standard of care and have achieved significant procedure volumes rapidly. For
example, according to Medical Data International, an independent research
organization, the number of laparoscopic surgical procedures performed annually
in the United States increased from approximately 84,000 in 1990 to more than an
estimated 2.4 million in 1995. Minimally invasive procedures are designed to be
as efficacious as conventional surgery, but with substantially reduced trauma.
Minimally invasive procedures are designed to reduce pain and suffering, speed
recovery, shorten the length of hospital stays and decrease many of the costs
associated with patient care. This movement toward minimally invasive surgery
has been driven by advances in both device technology and surgical technique, as
well as patient demand.
 
  MINIMALLY INVASIVE MICROSURGERY
 
    Minimally invasive microsurgery ("MIM") is an extension of minimally
invasive surgery, characterized by greater complexity and precision. MIM
procedures have been made possible primarily by recent advances in medical
technology. MIM is usually performed in very confined areas of the body,
involves critical anatomical structures, and often requires dissection and
reconstruction as well as excision. As a result, the Company believes that in
order for MIM procedures to be extensively adopted, surgeons must have access to
enhanced visualization and specialized instruments. Examples of MIM are emerging
procedures in cardiothoracic surgery and head, neck and spine ("HNS") surgery.
 
  CARDIOTHORACIC SURGERY
 
    CONVENTIONAL TREATMENTS.  Cardiovascular disease, the leading cause of death
in the United States, is typically treated with drugs, various surgical
procedures or both. The two principal types of cardiovascular disease are
coronary artery disease and valvular heart disease. Methods of accessing the
heart for treatment include surgically opening the chest, threading a
balloon-tipped catheter through a major artery or, most recently, gaining
surgical access via a small incision in the chest. Conventional cardiology
procedures include angioplasty, atherectomy and inserting coronary stents;
conventional surgical procedures include coronary artery bypass graft ("CABG")
and valve replacement or repair. Angioplasty, atherectomy and inserting coronary
stents involve the use of a balloon-tipped catheter which is threaded into the
heart through an artery in a patient's leg. Although these procedures are less
invasive than conventional CABG, a major drawback is the high rate of restenosis
or renarrowing of the blood vessel at the treatment site. Traditional CABG and
valve replacement or repair procedures
 
                                       30
<PAGE>
typically involve a sternotomy, whereby a surgeon makes a 12 to 18 inch incision
in the patient's chest, the sternum is cut in half with a bone saw, and the rib
cage is then spread open with a steel retractor to perform the grafting
procedures or to replace or repair the heart valves. According to the results of
a recent study, approximately one-third of all angioplasties experience
restenosis or renarrowing of the blood vessel at the treatment site within seven
months while the Company believes most traditional CABG procedures remain
effective for more than a decade.
 
    According to the most recent data published by the American Heart
Association, there were approximately 628,000 open heart surgical procedures
performed in the United States in 1994. Of these, 501,000 were CABG procedures,
60,000 were valve procedures and 67,000 were other procedures including
congenital and pediatric repairs. The Company believes that worldwide there are
approximately 800,000 CABG procedures and approximately 100,000 valve
replacement or repair procedures performed each year.
 
    CARDIOTHORACIC MIM.  The application of minimally invasive techniques to
cardiothoracic surgery is commonly regarded as a revolutionary development in
modern surgery. Minimally invasive CABG and valve replacement or repair
procedures avoid the trauma caused by sternotomy and promise to significantly
decrease pain and trauma and shorten recovery times. The minimally invasive
approaches to surgical intervention are evolving and include methods performed
on either a beating or arrested heart. While few agree on the ultimate form of
the emerging techniques and practices, nearly all of those involved believe that
minimally invasive procedures will change the future practice of cardiothoracic
surgery, just as laparoscopy has revolutionized general surgery. However,
cardiothoracic MIM requires the surgeon to perform technically challenging
procedures, including working on tiny delicate structures (such as a one
millimeter heart vessel) with highly restricted access through small incisions.
The Company believes that a current limitation to widespread adoption of
cardiothoracic MIM is the non-existent or restricted visibility through keyhole
access or the minimal incisions currently used. As a result of these factors,
cardiothoracic MIM requires enhanced visualization, specialized instruments and
surgeon training in the new MIM techniques.
 
    THE VISTA MEDICAL SOLUTION.  The Company believes that an advanced
visualization technology which provides the surgeon with an intuitive and
ergonomic solution to the inherent vision restrictions of the MIM approach will
enable the use of the MIM technique with increased safety, efficacy and
precision. In the cardiothoracic MIM area, the Company's proprietary
technologies are equally applicable whether the surgeon elects to use either a
beating or arrested heart approach. In addition, the enhanced visualization
provided by the Company's products is expected to enable a significant number of
surgeons, who otherwise might be reluctant to perform MIM, to adopt the
procedures, thereby accelerating the rate of conversion towards a standard of
care. Finally, there is growing evidence of patient interest and demand for
cardiothoracic MIM procedures.
 
  HEAD, NECK AND SPINE (HNS) SURGERY
 
    CONVENTIONAL HNS TREATMENTS.  Conventional head, neck and spine procedures
are often invasive and involve a lengthy and painful recovery. Neurosurgical
procedures involving the brain and spinal cord have traditionally been performed
under microscopic visualization to facilitate the delicate manipulations and
extreme precision which are required. More recently, the visualization system
often includes neuroendoscopes in combination with microscopes. The Company
estimates there were approximately 315,000 neurosurgical and skull base
procedures, 430,000 surgical sinus procedures and 650,000 spinal procedures
performed in the United States in 1995.
 
    HNS MIM.  The Company believes that there are significant opportunities to
advance MIM techniques in HNS procedures which involve manipulation in close
proximity to critical anatomical structures. The visualization techniques
currently available for these procedures are limited. Existing fiberoptic
neuroendoscopes have inferior resolution, do not provide depth perception and
require a surgeon to
 
                                       31
<PAGE>
view the procedure on a video monitor. The position required for both the
principal and assistant surgeon to utilize a surgical microscope is both
ergonomically awkward and physically uncomfortable. In addition, many of these
procedures require the simultaneous monitoring of multiple information sources,
including the images used in the emerging technique of image guided surgery.
Image guided surgery converts the output from digital imaging modalities, such
as magnetic resonance imaging (MRI) and computerized tomography (CT) into highly
precise 3-D and volumetric computer models which help the surgeon with
pre-operative planning. In addition, image guided surgery helps the surgeon
choose the least destructive path when operating close to critical anatomy and
to locate and remove tissue with the highest degree of safety and accuracy.
 
    THE VISTA MEDICAL SOLUTION.  In the HNS MIM area, the Company's products
incorporate 3-D visualization into a small diameter endoscope which provides the
surgeon with the critical element of depth perception missing from conventional
endoscopes. In addition, the endoscopic image in the head-mounted display worn
by an assistant surgeon who is operating directly across from the principal
surgeon can be electronically reversed in order to align the assistant's
movements with those of the principal surgeon. The Company can also retrofit
surgical microscopes, so that both the principal surgeon and assistants can view
the case simultaneously on their head-mounted displays in 3-D, with superior
comfort and ergonomic positioning.
 
BUSINESS STRATEGY
 
    The Company's business strategy is to become the leading developer and
marketer of advanced visualization and information systems for MIM applications
in cardiothoracic, HNS and other selected surgical specialties. Key elements of
the Company's strategy include:
 
    ESTABLISH ADVANCED VISUALIZATION TECHNOLOGIES AS STANDARD PRACTICE IN
MINIMALLY INVASIVE CARDIAC SURGERY.  The Company believes that it has the only
visualization system specifically designed for minimally invasive cardiac
surgery. The Company is currently working with its Cardiac Clinical Advisory
Board and other leading surgeons to develop operating protocols which
incorporate advanced visualization technologies as standard practice. The
Company then intends to provide training in these protocols, including the use
of the Company's visualization system, to other cardiac surgeons to accelerate
the general rate of conversion to MIM procedures, whether performed on a beating
or arrested heart.
 
    PROMOTE VISTA MEDICAL'S VISUALIZATION SOLUTION FOR USE IN ALL TYPES OF
CARDIAC SURGERY.  The Company believes that its technology is applicable to all
types of cardiac surgery, whether minimally invasive or conventional open heart,
especially where enhancement of the surgeon's view is particularly critical. The
Company believes that use of its advanced visualization product in open heart
surgeries will enhance visualization, improve the quality of procedures and
result in shorter operating times and reduced costs.
 
    DEVELOP MIM APPLICATIONS THROUGH SPECIALTY-FOCUSED BUSINESS UNITS BY
LEVERAGING THE COMPANY'S TECHNOLOGY PLATFORM.  The Company approaches its target
markets via its focused business units, the CardioThoracic Surgery division and
the HNS Microsurgery division. The business units concentrate on the specific
requirements of their target markets, with dedicated clinical marketing
programs, clinical advisory boards, sales forces and customer support teams for
the introduction and support of the Company's products. The Company's strategy
is to optimize its fundamental technology platform for each of these medical
specialties and to develop appropriate partnership and distribution systems both
in the United States and international markets.
 
    ACCELERATE ADOPTION OF THE SERIES 8000 ADVANCED VISUALIZATION AND
INFORMATION SYSTEM IN THE CARDIAC MARKET BY IMPLEMENTING A PER-PROCEDURE PRICING
STRATEGY.  The Company believes that it can accelerate the adoption of its
Series 8000 advanced visualization and information system by
 
                                       32
<PAGE>
implementing a per-procedure pricing strategy. This strategy would require a
payment to the Company every time the Series 8000 is used in a procedure. The
Company commissioned market research in order to determine the viability of a
per-procedure pricing strategy in the United States market. The results of this
market research support the Company's belief that an integrated equipment and
service package, including installation, in-service training, on-going technical
support and system upgrades for a single procedure-based charge will maximize
market penetration and accelerate roll-out of the product line.
 
    INCREASE THE SURGEON'S REAL-TIME ACCESS TO CRITICAL DATA.  The surgeon's
access to critical monitoring and diagnostic data, on demand, in real time and
integrated with the anatomical image, enhances procedure performance. The
Company's head-mounted display, incorporating picture-in-picture capability, is
designed to give the surgeon this real-time access to critical information
integrated with the anatomical images generated by the Company's camera systems.
 
    ENTER INTO STRATEGIC RELATIONSHIPS WHICH COMPLEMENT COMPANY RESOURCES.  The
Company intends to leverage its position in both technology and distribution by
forming strategic alliances with partners. In November 1996, the Company and
Medtronic, Inc. ("Medtronic"), a leading cardiac company, entered into a
strategic alliance providing for the distribution and co-promotion of the
Company's current and future visualization and information systems for cardiac
surgery, including the Vista Systems. Medtronic will co-promote the product line
in the United States and Canada and act as the Company's exclusive distributor
in Europe, the Middle East (excluding Afghanistan and Pakistan) ("Middle East")
and Africa. In February 1997, the Company entered into an agreement with
Heartport, Inc. ("Heartport"), one of the leading companies applying minimally
invasive surgical techniques to cardiothoracic surgery. Vista Medical will sell
four Series 8000 systems to Heartport, for use in Heartport's Research and
Training Center in Salt Lake City, Utah. The Company has also formed strategic
partnerships with Cogent Light Technologies ("Cogent Light") and GDE Systems,
Inc. ("GDE") to incorporate light source and information technologies,
respectively, into its products. The Company expects to pursue additional
strategic relationships.
 
ADVANCED VISUALIZATION PRINCIPLES AND PRODUCT PLATFORM
 
    Vista Medical's proprietary technology is based on the following principles
which the Company believes are both essential in advancing the techniques of MIM
and offer several key advantages over other visualization approaches:
 
    - 3-D VIEW. The surgeon's ability to view the principal anatomical image in
      3-D provides the accurate depth perception necessary so that vital
      anatomical structures are accurately identified and located, thereby
      improving safety, precision and speed of the procedure.
 
    - HIGH RESOLUTION IMAGES. The availability of a high resolution image which
      can be electronically managed under the surgeon's control significantly
      enhances the surgeon's ability to differentiate critical tissues in a
      confined setting and perform intricate dissection and reconstruction as
      well as excision.
 
    - ACCESS. The surgeon benefits from miniaturization technology which allows
      for the direct insertion of a camera into the body cavities or organs and
      provides high quality images from an optimal anatomical orientation.
 
    - ERGONOMICS. Due to the complex and time consuming nature of MIM
      procedures, the surgeon requires an ergonomic display system which allows
      comfortable operating posture and maximizes hand-eye coordination without
      strain.
 
    - INFORMATION INTEGRATION. The surgeon's access to critical monitoring and
      diagnostic data, on demand, in real time and integrated with the
      anatomical image within the surgeon's visual field, enhances procedure
      performance.
 
                                       33
<PAGE>
    The Company has applied its proprietary technology by incorporating the
above principles into its visualization product platform.
 
  HEAD-MOUNTED DISPLAY
 
    The head-mounted display ("HMD") was originally developed for mission
critical applications in military aerospace by Kaiser Aerospace, one of the
world's leading manufacturers of head-mounted displays for aviation
applications. The HMD was determined by the Company to be the optimal solution
to the display challenge of MIM. The fundamental technology and human factors
experience incorporated in the Company's HMD was originally developed by Kaiser
Aerospace and is the result of substantial investment in the technologies of
advanced aerospace display systems and incorporates extensive human factors
experience. This human factors knowledge, derived from many years of analysis
into the display characteristics which enable pilots performing critical
physical tasks to simultaneously absorb and react to crucial information, is a
key element in the Company's HMD design. The Vista Medical HMD, the first
specifically designed for surgical use, provides 3-D visualization of an
endoscopic or microscopic image, has the capability of integrating relevant data
and presents the images to a surgeon in an optically correct, intuitive and
ergonomic way. Wearing the HMD, the microsurgeon can also perform surgery
"in-line" -- the natural way people perform micro-critical tasks -- eyes, hands,
instruments and subject in line. This is not the case when the surgeon is
observing the anatomy on a remotely-positioned video monitor.
 
    The Company's HMD is a lightweight, high resolution display designed to
allow the surgeon to view information on demand, whether such information is
generated from attached endoscopes, microscopes or monitoring equipment in the
operating room. It is presently contemplated that further enhancements to the
HMD will allow for voice-activated control and information display from other
diagnostic equipment in the hospital or from remote locations via information
networks. The video display in the HMD is fixed in relation to the surgeon's
eyes, but his or her head may move into any position necessary for comfort. The
HMD design allows the surgeon to have a constant view of the surgical anatomy
required for the procedure as well as full awareness of the surroundings in the
operating room. The HMD is designed to provide a true 3-D image by replicating
the way the human visual system works -- left and right acquired images are
delivered directly to left and right liquid crystal displays. The HMD is
designed so that it can be worn with conventional surgical loupes.
 
  THREE-DIMENSIONAL IMAGE ACQUISITION
 
    Vista Medical believes that 3-D visualization capability is critical in MIM
procedures such as cardiothoracic and neurosurgical procedures. The Company's
technology for stereo visualization consists of the following proprietary
elements: the optical system, the stereo camera and the stereo processor. The
3-D endoscopic optical system employed by Vista Medical was originally developed
and patented by noted optical designer, Mr. H. McKinley, and is licensed
exclusively to the Company for medical applications. The system is designed to
replicate the exact view that the surgeon would have if the procedures were
being performed open and he or she had direct sight of the anatomy. The Company
believes that the McKinley optical system will provide it with a significant and
enduring competitive advantage because it provides natural depth perception, and
it can be packaged with twin cameras in a very compact design. The twin cameras
acquire the image in a manner analogous to a human's two eyes.
 
    Vista Medical's technology packages the twin cameras in two ways. In the
first method, a micro-camera is attached to the end of a flexible or rigid guide
which can then be inserted directly into the body cavity and organs. The image
is directly captured by the camera chips without being transmitted through
multiple rod lenses as in a conventional optical endoscope design. The
elimination of optical surfaces produces several important advantages, including
increased image quality, improved contrast, better reliability and improved
ability to sterilize by autoclaving. Alternatively, for applications where a
standard optical endoscope configuration remains preferable, a stereo
micro-camera can be mounted externally on a stereo endoscope. The image acquired
by either approach is then processed for display by control electronics
developed exclusively by the Company. The controller will also include image
management
 
                                       34
<PAGE>
features which will contribute significantly to procedure performance, such as
zoom control, dual image presentation and picture-in-picture.
 
  INFORMATION MANAGEMENT
 
    Medicine is an information rich discipline, but the provision of relevant
information in real-time to surgeons has not been developed to the levels
attained, for example, in military aviation. The HMD is designed to give the
surgeon real-time access on demand to critical information, integrated with the
anatomical images generated by the Company's camera systems. Therefore, the
surgeon will be able to command the diagnostic and monitoring information
relevant to the specific procedure while it is taking place. In addition to
real-time display, the information can be managed (stored or transmitted) within
the hospital or to remote locations for training, advisory or administrative
purposes. The applications software to control this flow of information is a key
element in Vista Medical's long-term product strategy, which positions
visualization within the context of a total information service to the surgeon.
 
    The Company's data integration capability has been enhanced by the recent
exclusive license from GDE which has added high speed image-based information
processing and networking software to the Company's technology platform. The
Company believes that its technology will demonstrate that real-time access to
relevant information, along with enhanced visualization, is a critical
requirement of performing MIM and other surgical procedures.
 
PRODUCT LINES
 
    Vista Medical develops products based on the Company's core technology and
product platform described above, that are customized for the specific
cardiothoracic and HNS procedures to which they are directed. The Company's
product lines are as follows:
 
           SERIES 8000 ADVANCED VISUALIZATION AND INFORMATION SYSTEM
 
    The Company has developed the Series 8000 for minimally invasive and other

  OTHER PRODUCTS
 
    RELATED CARDIOTHORACIC AND HNS PRODUCTS.  The Company's CardioThoracic
Surgery division is the exclusive North American distributor of instruments
manufactured by Delacroix-Chevalier, a French corporation, and sutures
manufactured by Peters, a French corporation, which are particularly appropriate
for the minimally invasive approach. The Company's HNS Microsurgery division is
the United States distributor of a line of hand instruments for functional
endoscopic sinus surgery, including exclusive distribution of instruments
developed by Dr. Hiroshi Moriyama of Jikei University, Tokyo.
 
                                       36
<PAGE>
    3-CHIP CAMERA.  3-chip cameras are the state-of-the-art in two-dimensional
endoscopic imaging. The Company currently manufactures a compact, high
resolution 3-chip camera under its own label and for OEM customers and strategic
partners. This product has historically accounted for a significant portion of
the Company's revenues.
 
    ELECTRONIC ZOOM LAPAROSCOPE (EZL).  The EZL represents a new generation of
laparoscopes in which the camera is placed on the distal end of the endoscope
and then inserted inside the body. The EZL incorporates Vista Medical's unique
proprietary zoom feature, which allows a surgeon to manipulate the image by
zooming in and out at the touch of a button, while remaining in focus and
without moving the scope. This capability is not available in any other
currently marketed endoscope and the Company is currently seeking a strategic
partner with distribution capability in laparoscopy. The Company may also
utilize the zoom technology in future products for the CardioThoracic Surgery
and HNS Microsurgery divisions.
 
STRATEGIC ALLIANCES
 
    The Company intends to leverage its position in both technology and
distribution by forming strategic alliances with corporations and research
institutions with respect to the development, regulatory approval and marketing
of certain of its products. The Company has entered into strategic partnering
arrangements as follows:
 
  MEDTRONIC
 
    In November 1996, Vista Medical and Medtronic, a leading cardiac company,
entered into a strategic alliance providing for the distribution and
co-promotion of the Company's current and future visualization and information
systems for cardiac surgery, including the Series 8000 (the "Vista Systems").
The parties entered into a co-promotion agreement for the United States and
Canada under which Medtronic will promote the Vista Systems in conjunction with
Medtronic's own proprietary products for minimally invasive cardiac surgery.
Vista Medical will be responsible for the sale and distribution of the Vista
Systems to customers in the United States and Canada. The Company will be
responsible for obtaining all regulatory clearances in the United States and
Canada, will provide training and installation at its expense and will pay
Medtronic a sales commission based on net revenues generated by the installation
and use of the Vista Systems in the United States and Canada. During the term of
the co-promotion agreement, Medtronic has agreed not to market or sell in the
United States and Canada visualization products which are competitive with Vista
Medical in cardiothoracic surgical procedures. Medtronic's right to co-promote
will terminate in December 1999, subject to (i) earlier termination for
Medtronic's failure to meet certain objectives or breach of material obligations
by either party and (ii) automatic renewal if certain performance criteria are
met.
 
    Medtronic will also act as Vista Medical's exclusive distributor for the
Vista Systems for use in cardiothoracic surgical procedures in Europe, the
Middle East and Africa. Medtronic will be responsible for obtaining all
regulatory clearances other than the CE mark and will provide training and
installation at its expense. Medtronic will purchase the Vista Systems for a
transfer price to be adjusted each year. Medtronic's exclusive distributorship
will terminate on the third anniversary of the initial commercial release of the
Vista Systems in Europe, subject to earlier termination for Medtronic's failure
to meet certain objectives or breach of material obligations by either party.
 
    The initial term of co-promotion and/or distributorship will be
automatically renewed for an additional two-year term provided certain
performance criteria are met. Vista Medical retains the worldwide right to
distribute products based upon the technology incorporated in the Vista Systems
for use in specialties other than cardiac surgery. Vista Medical also retains
the right to make the Vista Systems available worldwide (other than in Europe,
the Middle East and Africa) for clinical and training programs organized by any
company. Medtronic has the right of first refusal to obtain distribution rights
for the Vista Systems in other areas of the world.
 
                                       37
<PAGE>
    In conjunction with entering into the co-promotion agreement, Medtronic made
a $10 million equity investment in the Company.
 
  HEARTPORT
 
    In February 1997, the Company entered into a Supply and Services Agreement
with Heartport, a leading company developing minimally invasive technology for
heart surgery. Vista Medical will sell four Series 8000 systems to Heartport,
for use in the Heartport Research and Training Center in Salt Lake City, Utah.
The four systems are scheduled to be delivered by approximately September 1997
or as soon as possible thereafter. Heartport has agreed to use the Series 8000
in its training centers, to promote that its training courses utilize the Series
8000 and to endorse the Series 8000 as the preferred 3-D video visualization and
information solution for minimally invasive heart surgery. Until December 31,
1999, the Company will maintain and support the four systems at the Heartport
Research and Training Center and will collaborate with Heartport with the goal
of ensuring that the Series 8000 is compatible with technology used in the
performance of Heartport's Port-Access procedures. During the period ending
December 31, 2003, the Company has also agreed to provide the Vista Systems to
hospitals, clinics or similar sites in North America whose surgeons have been
trained at the Heartport Research and Training Center, without discrimination
and on the best available terms and conditions the Company offers to any other
similarly situated customers of the Company. In connection with the agreement,
the Company issued to Heartport a warrant to purchase up to 100,000 shares of
Common Stock, exercisable at any time after this Offering and prior to March 31,
2001, at a price per share equal to the initial public offering price.
 
  GDE SYSTEMS
 
    In February 1997, GDE, a leading military electronics and information
management company, granted the Company an exclusive worldwide license to
software, documentation and trademarks of GDE for use in the medical field.
Since 1993, GDE's subsidiary, Healthcom, has been adapting the software licensed
to Vista Medical to provide high-speed, image-based information processing and
networking capabilities specifically for medical applications. In connection
with the license, Vista Medical will issue to GDE Common Stock with a value
(based on the initial public offering price) of $250,000 and will pay GDE a
royalty on revenues derived from any products based upon or derived from the GDE
software. Vista Medical has also agreed to make a non-refundable payment of at
least $250,000 by December 31, 1998 as a combination of royalty payments earned
through such date and a royalty advance creditable against future royalties due
thereafter. Pursuant to the license agreement, Vista Medical has the opportunity
to hire up to three of GDE's software development engineers. GDE has a right of
first refusal to license Vista Medical improvements to the software for use in
non-medical markets, subject to the payment of a royalty to Vista Medical. The
parties also agreed to negotiate in good faith to enter into a services
agreement which would provide Vista Medical with access to GDE consultancy
services on a project-by-project basis, on terms to be mutually agreed upon.
 
  COGENT LIGHT
 
    The Company and Cogent Light formed a strategic alliance in March 1996,
pursuant to a memorandum of understanding, to cooperate in the development of
products for minimally invasive cardiac surgery which incorporate Cogent Light's
proprietary light fiber delivery technology. Pursuant to the memorandum of
understanding, Cogent Light is currently providing its single fiber and
MicroBundle technologies exclusively for incorporation into the Series 8000,
including CardioCamera, CardioLight and Cardio3DScope. The memorandum of
understanding stipulates that Vista Medical will incorporate only a Cogent Light
source in its cardiac surgical instrumentation, for example, CardioLight,
provided such light source meets all of Vista Medical's performance
requirements. The parties retain rights to their respective intellectual
property, with new developments under the alliance being jointly owned and
cross-licensed to each party.
 
                                       38
<PAGE>
  UROHEALTH
 
    In December 1996, the Company and Urohealth Systems, Inc. ("Urohealth")
entered into a license agreement under which the Company exclusively licensed
visual instrument technology developed principally for the field of gynecology
(the "Newman Technology") to Urohealth for use in gynecology, urology and
general surgery on a worldwide basis. Vista Medical has a right of first refusal
to manufacture Urohealth's requirements for the camera and light source
equipment required for medical office use of the products derived from the
Newman Technology for a specified period of time following the date of the
agreement. Urohealth will pay to Vista Medical a sliding royalty based on sales
of products incorporating the Newman Technology, subject to certain maximums and
minimums. The agreement may be terminated in the event of an uncured material
breach or insolvency by either party. In connection with the license agreement,
the parties entered into a consulting agreement whereby Vista Medical agreed to
use its reasonable efforts to provide the services of Allen Newman, the
Company's Vice President and General Manager, HNS Microsurgery, as a consultant
to Urohealth on a limited basis. The Company exclusively licensed the Newman
Technology from Mr. Newman in September 1994. The Newman license agreement was
amended in December 1996 to permit the Company to sublicense the Newman
Technology to Urohealth. In connection with the amendment of the Newman license
agreement, including the termination of royalty rights for camera systems, the
Company paid Mr. Newman an additional sum of money and agreed to pay Mr. Newman
a percentage of the royalties received from Urohealth for sales of disposable
products manufactured under the sublicense.
 
MARKETING AND SALES
 
    The Company has organized its sales and marketing efforts by
specialty-specific divisions: Vista CardioThoracic Surgery division ("VCS") and
Vista HNS Microsurgery division ("VHNS"). The Company believes that this
organizational structure provides the commitment and focus necessary to
introduce and support new advanced technology to these two distinct markets.
Each division, however, will follow similar strategic principles in developing
its business.
 
    TRAINING.  The introduction of new technology requires training for both
surgeons and operating room personnel. VCS intends to establish training
programs by mid-1997 and expects to be able to train up to 250 surgeons each
year, and will also provide the visualization equipment for training programs
organized by Medtronic, Heartport and other cardiac surgery companies. The VCS
training format will involve one or two day sessions at selected locations where
surgeons will have the opportunity to use the Series 8000 in a laboratory
environment. Operating room personnel will receive in-service training from
company representatives when equipment is installed. VHNS intends to utilize a
similar format specifically designed for HNS surgeons. See "-- Strategic
Alliances."
 
    CLINICAL EVALUATION.  VCS and VHNS product lines have been developed with
frequent input from the Clinical Advisory Boards of each division. Once
marketing begins, this evaluation phase is expected to progress into a
publication phase with the Company's advisors publishing results of their
experience in leading publications and speaking at major clinical conferences.
The Company supports such research, although it has no control over the content
or timing of any publication or presentation, because impartial education of the
general clinical audience is a key component in establishing procedure and
equipment acceptance. As part of their strategy, VCS and VHNS also intend to
continue to support seminars and symposiums and participate in industry trade
shows.
 
    SALES FORCE.  VCS and VHNS will have separate sales forces, consisting of a
combination of direct and independent sales representatives. VCS currently
markets its products through two direct and 35 independent representatives and
is in the process of hiring up to 10 additional direct sales people to support
the introduction of the Series 8000. VHNS will market its products through a
similar combination of direct and independent sales representatives. VHNS
currently has two sales managers, one based in the United States and the other
in Europe.
 
                                       39
<PAGE>
    PATIENT EDUCATION.  As the success of the Company's products is dependent on
the adoption of MIM procedures, it must support the purchasers of its products
in the introduction of these procedures to the local community. The Company has
therefore engaged a national firm, specializing in medical communications, to
provide public relations assistance to create patient awareness of the minimally
invasive surgical options. Initial emphasis will be to support the launch of the
Series 8000.
 
    INTERNATIONAL SALES.  The Company markets its products internationally
through independent distributors and has entered into a strategic relationship
with Medtronic for the distribution of the Vista Systems in Europe, the Middle
East and Africa. See "-- Strategic Alliances -- Medtronic."
 
MANUFACTURING
 
    The Company has established a manufacturing facility in Westborough,
Massachusetts, which it believes generally meets the Good Manufacturing Practice
("GMP") standards set by the FDA. The Company believes this facility is adequate
for the Company's near-term manufacturing requirements which are principally
final assembly of sub-assemblies and components, including hardware and
software. The Company has been manufacturing OEM camera systems in limited
quantities for two years and has been developing the necessary procedures,
systems and controls and hiring supervisory staff throughout this period. The
Company believes that its current manufacturing facility will be adequate to
meet its forecasted requirements through 1997 and that additional space will be
available when required on reasonable commercial terms.
 
    The Company lacks experience in manufacturing its products under
development, including the Series 8000, in the quantities that would be
necessary to achieve significant commercial sales. The manufacture of the
Company's products primarily involves the assembly of a number of sub-assemblies
and components either by the Company directly or by contract manufacturers.
Companies such as Vista Medical often encounter difficulties in scaling up
manufacturing of products, which could include problems involving quality
control and assurance, component and service availability, adequacy of control
policies and procedures, lack of qualified personnel, compliance with FDA
regulations and the need for further FDA review and possible approval of new
manufacturing processes and facilities or other production constraints. There
can be no assurance that reliable, high-volume manufacturing can be established
or maintained at commercially reasonable costs. The Company will also require
additional manufacturing facilities as production volumes increase; acquisition
of new manufacturing facilities will likely involve relocation. Any of these
factors could have a material adverse effect on the Company's business,
financial condition and results of operation.
 
    The Company uses or relies on certain components and services used in its
devices that are provided by sole source suppliers. The qualification of
additional or replacement vendors for certain components or services is a
lengthy process. In addition, the substitution of replacement vendors may entail
re-engineering time and cost and could delay the supply of the Company's
products. Any significant supply interruption would have a material adverse
effect on the Company's ability to manufacture its products and, therefore, a
material adverse effect on its business, financial condition and results of
operations.
 
    The Company has, and will continue to consider as appropriate, the internal
manufacture of sub-assemblies currently provided by third party subcontractors,
as well as the implementation of new design and production processes which
further reduce costs.
 
COMPETITION
 
    The medical device market is characterized by intensive development efforts
and rapidly advancing technology. The future success of the Company will depend,
in large part, upon its ability to anticipate and keep pace with advancing
technology and competing innovations. There can be no assurance,
 
                                       40
<PAGE>
however, that the Company will be successful in identifying, developing and
marketing new products or enhancing its existing products.
 
    Although several companies compete with aspects of the Company's
visualization product line, the Company believes there is no single company
which offers a complete and integrated advanced visualization and information
system specifically directed at minimally invasive microsurgical applications.
In addition, the Company believes that no other head-mounted display has been
cleared for marketing in surgical applications by the FDA. The Company believes
that a number of large companies, with significantly greater financial,
manufacturing, marketing, distribution and technical resources and experience
than that of the Company, are focusing on the development of visualization
products for MIM. Several companies are currently developing and marketing
visualization products for MIM which could be applied to cardiac surgery. There
can be no assurance that the Company will be successful in competing with any
such companies.
 
    Technological advances in other therapies for heart disease such as drugs,
interventional cardiology procedures or future innovations in cardiac surgery
techniques could make such other therapies more effective or lower in cost than
MIM surgical procedures and could render MIM cardiac surgery obsolete.
 
GOVERNMENT REGULATION
 
    The manufacture and sale of medical devices intended for commercial
distribution are subject to extensive governmental regulation in the United
States. Medical devices are regulated in the United States primarily by the FDA
and, to a lesser extent, by certain state agencies. Generally, medical devices
require pre-market clearance or pre-market approval prior to commercial
distribution. In addition, certain material changes or modifications to medical
devices also are subject to FDA review and clearance or approval. The FDA
regulates the research, testing, manufacture, safety, labeling, storage, record
keeping, promotion and distribution of medical devices in the United States and
the export of unapproved medical devices from the United States to other
countries. Noncompliance with applicable requirements can result in failure of
the government to grant pre-market clearance or approval for devices, withdrawal
of approval, total or partial suspension of production, fines, injunctions,
civil penalties, refunds, recall or seizure of products and criminal
prosecution.
 
    In the United States, medical devices are classified into one of three
classes, Class I, II or III, on the basis of the controls deemed by the FDA to
be necessary to reasonably ensure their safety and effectiveness. The Company's
products to date have either been classified as Class I or Class II devices.
 
    Class I devices are subject to general controls (e.g., established
registration and product listing, labeling, adulteration and misbranding
provisions and medical device reporting requirements and, unless exempt, to
pre-market notification and adherence to GMP standards). Class II devices are
subject to general controls and special controls (e.g., performance standards,
post-market surveillance, patient registries and FDA guidelines). Generally,
Class III devices are those that must receive pre-market approval by the FDA to
ensure their safety and effectiveness (e.g., life-sustaining, life-supporting
and implantable or new devices which have not been found to be substantially
equivalent to legally marketed devices). Class III devices ordinarily require
clinical testing to ensure safety and effectiveness and FDA approval prior to
marketing and distribution. The FDA also has the authority to require clinical
testing of Class I and Class II devices. A pre-market approval ("PMA")
application must be filed if a proposed device is not substantially equivalent
to a legally marketed predicate device or if it is a Class III device for which
the FDA has called for such application. A PMA typically takes several years to
be approved by the FDA.
 
    Generally, before a new device can be introduced into the market in the
United States, the manufacturer or distributor must obtain FDA clearance of a
510(k) notification or submission and approval of a
 
                                       41
<PAGE>
PMA application. If a medical device manufacturer or distributor can establish
that a device is "substantially equivalent" to a legally marketed Class I or
Class II device, or to a Class III device for which the FDA has not called for a
PMA, the manufacturer or distributor may seek clearance from the FDA to market
the device by filing a 510(k) notification. The 510(k) notification may need to
be supported by appropriate performance, clinical or testing data establishing
the claim of substantial equivalence. The FDA requires a rigorous demonstration
of substantial equivalence.
 
    The Company has received 510(k) clearance to market the following product
lines in the United States: (i) head mounted display (September 1996); (ii)
additional cardiothoracic indications for the 3-D scope (July 1996); (iii) sinus
telescopes (October 1995); (iv) video endoscope with zoom (January 1995); (v)
stereo viewing system (November 1994); (vi) dental camera (November 1994); (vii)
three-chip video camera (June 1994); and (viii) 3-D scope (December 1992). Three
510(k) pre-market notifications for the Company's 3-D video endoscope, mini
cameras and illumination system were filed in January 1997. Internationally, the
Company's three-chip video camera and the zoom endoscope have qualified for the
CE mark under the Electromagnetic Compatibility Directive for sale in Europe.
 
    Following submission of the 510(k) notification, the manufacturer or
distributor may not place the device into commercial distribution until a letter
clearing the 510(k) is issued by the FDA. At this time, the FDA typically
responds to the submission of a 510(k) notification within 90 to 200 days. An
FDA letter may declare that the device is substantially equivalent to a legally
marketed device and allow the proposed device to be marketed in the United
States. The FDA, however, may determine that the proposed device is not
substantially equivalent or requires further information, including clinical
data, to make a determination regarding substantial equivalence. Such
determination or request for additional information will delay market
introduction of the product that is the subject of the 510(k) notification.
 
    All clinical investigations involving the use of an unapproved or uncleared
device on humans to determine the safety or effectiveness of the device must be
conducted in accordance with the FDA's IDE regulations. If the device presents a
"significant risk," the manufacturer or distributor of the device is required to
file an IDE application with the FDA prior to commencing human clinical trials.
The IDE application must be supported by data, typically the result of animal
and, possibly, mechanical testing. If the IDE application is approved by the
FDA, human clinical trials may begin at a specific number of investigational
sites with a maximum number of patients, as approved by the FDA. If the device
presents a "non-significant risk," approval by an Institutional Review Board
prior to commencing human clinical trials is required, as well as compliance
with labeling, record keeping, monitoring and other requirements.
 
    Any products manufactured or distributed by the Company are subject to
continuing regulation by the FDA, which includes record keeping requirements,
reporting of adverse experience with the use of the device, GMP requirements and
post-market surveillance, and may include post-market registry and other actions
deemed necessary by the FDA. A 510(k) supplement, new 510(k) or PMA is also
required when a medical device manufacturer makes a change or modification to a
legally marketed device that could significantly affect the safety or
effectiveness of the device, or where there is a major change or modification in
the intended use of the device. When any change or modification is made to a
device or its intended use, the manufacturer is expected to make the initial
determination as to whether the change or modification is of a kind that would
necessitate the filing of a 510(k) supplement, new 510(k) or PMA.
 
    Sales of medical device products outside the United States are subject to
foreign regulatory requirements that vary from country to country. The time
required to obtain approvals required by foreign countries may be longer or
shorter than that required for FDA clearance, and requirements for licensing may
differ from FDA requirements. Failure to comply with regulatory requirements
could have a material adverse effect on the Company's business, financial
condition and results of operations. The current regulatory environment in
Europe for medical devices differs significantly from that in the United States.
Europe is currently in the transitional process of implementing the Medical
Device Directive which was adopted on January 1, 1995 with a transition period
through June 1998. After June 1998, all medical
 
                                       42
<PAGE>
devices sold in the European Union must bear the CE mark. Devices are now
classified by manufacturers according to the risks they represent with a
classification system giving Class III as the highest risk devices and Class I
as the lowest. Once the device has been classified, the manufacturer can follow
one of a series of conformity assessment routes, typically through a registered
quality system, and demonstrate compliance to a European Notified Body. After
that, the CE mark may be applied to the device. Maintenance of the system is
ensured through annual on-site audits by the Notified Body and a post-market
surveillance system requiring the manufacturer to submit serious complaints to
the appropriate governmental authority. With respect to the Series 8000, the
Company is responsible for gaining, at its expense, the CE mark in Europe.
Medtronic is responsible for obtaining, at its expense, all necessary regulatory
and other approvals required for sale in the Middle East and Africa.
 
PATENTS AND PROPRIETARY RIGHTS
 
    Vista Medical relies on a combination of technical leadership, patent, trade
secret, copyright and trademark protection and nondisclosure agreements to
protect its proprietary rights. As of February 28, 1997, the Company had
exclusive rights to 11 issued United States patents, 12 pending United States
patent applications, three issued foreign patents and 17 pending foreign
applications covering various aspects of its devices and systems. The Company
intends to file additional patent applications in the future. The failure for
such patents to issue could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The Company owns the following trademarks: 3D Scope-Registered Trademark-,
Design of Cone and Vista Medical Technologies & Design. In addition, the Company
has filed for trademark protection for the following: MIM, StereoSite,
CardioCamera, CardioZoom, Infomatix, CardioView, CardioController, CardioGuide,
CardioConsole and CardioLight.
 
    The Company's future success will depend, in part, on its ability to
continue to develop patentable products, enforce its patents and obtain patent
protection for its products both in the United States and in other countries.
The patent positions of medical device companies, including the Company,
however, are generally uncertain and involve complex legal and factual
questions. There can be no assurance that patents will issue from any patent
applications owned by or licensed to the Company or that, if patents do issue,
the claims allowed will be sufficiently broad to protect the Company's
technology. In addition, there can be no assurance that any issued patents owned
by or licensed to the Company will not be challenged, invalidated or
circumvented, or that the rights granted thereunder will provide competitive
advantages to the Company.
 
    The Company has in-licensed certain aspects of its technology. Failure of
the Company to retain rights to these technologies could have a material,
adverse effect on the Company's business, financial condition and results of
operations. In September 1995, McKinley granted to the Company a perpetual,
exclusive, worldwide license to make, have made, modify, use, lease, market,
sell and otherwise distribute certain endoscopes and other medical products
incorporating a stereo objective lens and/or a relay lens configuration for
medical purposes. Under the terms of this license agreement, Vista Medical is
obligated to pay McKinley an annual maintenance royalty, additional royalties
upon the sale of certain numbers of systems incorporating the McKinley
technology and royalties on net sales of products incorporating the McKinley
technology. The exclusive license granted under this agreement becomes a
non-exclusive license in the event Vista Medical fails to pay any royalties
following receipt of notice of such failure to pay. In addition, Vista Medical
has the right to terminate the agreement with limited notice.
 
    In June 1996, Fuji granted to the Company a non-exclusive license to certain
optical zoom technology for use in endoscopes. Vista Medical is obligated to pay
royalties on net sales of products in the United States which incorporate Fuji's
technology. Fuji may terminate the agreement if Vista Medical does not cure any
violation of the agreement within a limited period of time.
 
                                       43
<PAGE>
    The medical device industry has been characterized by extensive litigation
regarding patents and other intellectual property rights. Litigation, which
would result in substantial expense to the Company, may be necessary to enforce
any patents issued or licensed to the Company and/or to determine the scope and
validity of proprietary rights of third parties or whether the Company's
products, processes or procedures infringe any such third-party proprietary
rights. The Company may also have to participate in interference proceedings
declared by the United States Patent and Trademark Office, which could result in
substantial expense to the Company, to determine the priority of inventions
covered by the Company's issued United States patents or pending patent
applications. Furthermore, the Company may have to participate at substantial
cost in International Trade Commission proceedings to enjoin importation of
products which would compete unfairly with products of the Company. Any adverse
outcome of any patent litigation (including interference proceedings) could
subject the Company to significant liabilities to third parties, require
disputed rights to be licensed from or to third parties or require the Company
to cease using the technology in dispute.
 
    Patent applications in the United States are maintained in secrecy until a
patent issues, and patent applications in foreign countries are maintained in
secrecy for a period of time after filing. After such period of time, and
usually before the grant of the patent, patent applications in foreign countries
are published. While publication of discoveries in the scientific or patent
literature tends to lag behind actual discoveries and the filing of related
patent applications, such publication may enable the Company's competitors to
ascertain what areas of research or development the Company is engaged in prior
to the Company's receipt of patent protection in the United States or foreign
countries relating to such research or development.
 
    In general, the development of visualization and information systems and
related surgical instruments and accessories is intensely competitive. Patents
issued and patent applications filed relating to medical devices are numerous
and there can be no assurance that current and potential competitors and other
third parties have not filed or in the future will not file applications for, or
have not received or in the future will not receive, patents or obtain
additional proprietary rights relating to products or processes used or proposed
to be used by the Company. There can also be no assurance that third parties
will not assert infringement claims against the Company in the future or that
any such assertions will not result in costly litigation or require the Company
to obtain a license to intellectual property rights of such parties. There can
be no assurance that any such licenses would be available on terms acceptable to
the Company, if at all. Furthermore, parties making such claims may be able to
obtain injunctive or other equitable relief that could effectively block the
Company's ability to make, use, sell or otherwise practice its intellectual
property (whether or not patented or described in pending patent applications),
or to further develop or commercialize its products in the United States and
abroad and could result in the award of substantial damages. Defense of any
lawsuit or failure to obtain any such license could have a material adverse
affect on the Company.
 
    The Company relies on unpatented trade secrets to protect its proprietary
technology, and no assurance can be given that others will not independently
develop or otherwise acquire the same or substantially equivalent technologies
or otherwise gain access to the Company's proprietary technology or disclose
such technology or that the Company can ultimately protect its rights to such
unpatented proprietary technology. No assurance can be given that third parties
will not obtain patent rights to such unpatented trade secrets, which patent
rights could be used to assert infringement claims against the Company. The
Company also relies on confidentiality agreements with its collaborators,
employees, advisors, vendors and consultants to protect its proprietary
technology. There can be no assurance that these agreements will not be
breached, that the Company would have adequate remedies for any breach or that
the Company's trade secrets will not otherwise become known or be independently
developed by competitors. In addition, the Company's agreements with its
employees and consultants require disclosure to the Company of ideas,
developments, discoveries or inventions conceived during employment or
consulting, as the case may be, and assignment to the Company of proprietary
rights to such matters related to the business and technology of the Company.
The extent to which efforts by
 
                                       44
<PAGE>
others will result in patents and the effect on the Company of the issuance of
such patents is unknown. Failure to obtain or maintain patent and trade secret
protection, for any reason, could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
CLINICAL ADVISORY BOARDS
 
    The Company has established two Clinical Advisory Boards made up of leading
surgeons, one focused on minimally invasive cardiac surgery, the other focused
on HNS microsurgery and a number of other specialties. Members of the Clinical
Advisory Boards consult with the Company exclusively in the field of
visualization, but may also consult with other non-competing instrumentation
companies and are employed elsewhere on a full-time basis. The Clinical Advisory
Boards are intended to act as a clinical reference for the Company and to
provide access to potential training sites for the Company's visualization
products. The Clinical Advisory Boards and their members are as follows:

approximately 22,500 square feet in Westborough, Massachusetts in which the
Company's development and manufacturing operations and the CardioThoracic
Surgery division are located, pursuant to several leases which expire at various
points in time beginning in May, 1999 and ending in October 2001. The Company
believes that suitable additional space will be available to it, when needed, on
commercially reasonable terms.
 
LEGAL PROCEEDINGS
 
    As of the date of this Prospectus, the Company is not a party to any legal
proceedings. Notwithstanding the foregoing, from time to time, Vista Medical may

(2) The exercise price per share of options granted represented the fair market
    value of the underlying shares of Common Stock on the dates the respective
    options were granted as determined by the Board, considering all relevant
    factors. The exercise price may be paid in cash or in shares of Common Stock
    valued at fair market value on the exercise date or a combination of cash or
    shares or any other form of consideration approved by the Board. After the
    effective date of the Registration Statement of which this Prospectus is a
    part, the fair market value of shares of Common Stock will be determined in
    accordance with certain provisions of the Plan based on the closing selling
    price per share of a share of Common Stock on the date in question on the
    primary exchange or national market system on which the Company's common
    stock is listed or reported. If shares of the Common Stock are not listed or
    admitted to trading on any stock exchange nor traded on the Nasdaq National
    Market, then the fair market value shall be determined by the Plan
    Administrator after taking into account such factors as the Plan
    Administrator shall deem appropriate.
 
(3) The 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the Commission. The price used for computing this
    appreciation is the exercise price of the

    options, not the price of Common Stock in this Offering. There is no
    assurance provided to any executive officer or any other holder of the
    Company's securities that the actual stock price appreciation over the
    10-year option term will be at the assumed 5% or 10% levels or at any other
    defined level.

(1) "Value realized" is calculated on the basis of the fair market value of the
    Common Stock on the date of exercise minus the exercise price and does not
    necessarily indicate that the optionee sold such stock.
 
(2) The options are immediately exercisable, but subject to vesting over a
    period of time.
 
(3) "Value" is defined as fair market price of the Common Stock at fiscal
    year-end ($0.80) less exercise price.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    During the year ended December 31, 1996, the Compensation Committee of the
Company's Board established the levels of compensation for the Company's
executive officers. The members of the Company's Compensation Committee are Dr.
Blair and Mr. Binkley. See "Certain Transactions." Mr. Lyon, the Company's
President and Chief Executive Officer, participated in the deliberations of the
Compensation Committee regarding executive compensation that occurred during
1996, but did not take part in the deliberations regarding his own compensation.
 
EMPLOYMENT ARRANGEMENTS
 
    Fifty percent of the unvested shares subject to options outstanding to the
Company's executive officers will immediately vest if the Company is acquired by
a merger or asset sale, unless the Company's repurchase rights with respect to
those shares are transferred to the acquiring entity. The other 50% of the
shares vest if the employee is terminated without cause within two years of the
merger or asset sale. See "Benefit Plans -- 1997 Stock Option/Stock Issuance
Plan."
 
DIRECTOR COMPENSATION
 
    The Company reimburses its directors for all reasonable and necessary travel
and other incidental expenses incurred in connection with their attendance at
meetings of the Board. Directors are not currently compensated for serving on
the Board. However, under the 1997 Stock Option/Issuance Plan
 
                                       52
<PAGE>
(the "Plan"), as amended, which was adopted in February 1997 and amended in
March 1997, beginning with the first annual meeting of stockholders following
this Offering, each non-employee director who is first elected to the Board will
automatically receive an option to purchase 15,000 shares of Common Stock for
the first year of the director's Board term and 5,000 shares of Common Stock for
each additional year remaining on the director's Board term following the
automatic option grant. Each director who is currently serving on the Board will
receive an option to purchase 5,000 shares of Common Stock for each additional
year for which he is elected as a director. These options will have an exercise
price equal to 100% of the fair market value of the Common Stock on the grant
date. The grant of 15,000 shares will become exercisable in equal monthly
installments over four years of Board service completed by the director
following such grant, and the grants of 5,000 shares will become exercisable at
the end of one year of Board service completed by the director following the
date of grant. See "-- Benefit Plans -- 1997 Stock Option/Issuance Plan."
 
    Under the Company's 1995 Stock Option Plan (the "Predecessor Plan"), each
non-employee director received a fully vested option to purchase 4,500 shares of
Common Stock in December 1996, and Mr. Lyon received an option to purchase
11,250 shares of Common Stock of the Company. The option grant to Mr. Lyon vests
over five years, subject to acceleration upon a change of control. Fifty percent
of the shares subject to Mr. Lyon's option will immediately vest in the event
the Company is acquired by a merger or asset sale, unless the Company's
repurchase rights with respect to those shares are transferred to the acquiring
entity. The other 50% of the shares will immediately vest if Mr. Lyon is
terminated without cause within two years of the merger or asset sale.
 
BENEFIT PLANS
 
  1997 STOCK OPTION/STOCK ISSUANCE PLAN
 
    The Plan serves as the successor equity incentive program to the Predecessor
Plan. The Plan became effective on February 28, 1997 upon adoption by the Board
and approval by the stockholders. 2,820,000 shares of Common Stock have been
authorized for issuance under the Plan. This share reserve is comprised of (i)
the shares that remain available for issuance under the Predecessor Plan,
including the shares subject to outstanding options thereunder, plus (ii) an
additional increase of 1,417,489 shares. However, in no event may any one
participant in the Plan receive option grants or direct stock issuances for more
than 50,000 shares in the aggregate per calendar year.
 
    Outstanding options under the Predecessor Plan were incorporated into the
Plan upon its adoption, and no further option grants will be made under the
Predecessor Plan. The incorporated options will continue to be governed by their
existing terms, unless the Plan Administrator (described below) elects to extend
one or more features of the Plan to those options. However, except as otherwise
noted below, the outstanding options under the Predecessor Plan contain
substantially the same terms and conditions summarized below for the
Discretionary Option Grant Program in effect under the Plan.
 
    The Plan is divided into three separate components: (i) the Discretionary
Option Grant Program under which eligible individuals in the Company's employ or
service (including officers and other employees, non-employee Board members and
independent consultants) may, at the discretion of the Plan Administrator, be
granted options to purchase shares of Common Stock at an exercise price not less
than 85% of their fair market value on the grant date, (ii) the Stock Issuance
Program under which such individuals may, in the Plan Administrator's
discretion, be issued shares of Common Stock directly, through the purchase of
such shares at a price not less than 100% of their fair market value at the time
of issuance or as a bonus tied to the performance of services and (iii) the
Automatic Option Grant Program under which option grants will automatically be
made at periodic intervals to eligible non-employee Board members to purchase
shares of Common Stock at an exercise price equal to 100% of their fair market
value on the grant date.
 
                                       53
<PAGE>
    The Board or a committee appointed by the Board (the "Plan Administrator")
will administer the Discretionary Option Grant and Stock Issuance Programs. The
Plan Administrator, subject to the provisions of the plan, will have complete
discretion to determine which eligible individuals will receive option grants or
stock issuances, the time or times at which such option grants or stock issuance
are to be made, the number of shares subject to each such grant or issuance, the
vesting schedule to be in effect for the option grant or stock issuance, the
maximum term for which any granted option is to remain outstanding and whether
an option will be granted as an incentive stock option or a non-statutory stock
option under the Federal tax laws. The administration of the Automatic Option
Grant Program will be self-executing in accordance with the express provisions
of such Program and no Plan Administrator will exercise any discretionary
functions with respect to any option grants or stock issuances made under the
Program.
 
    Under the Automatic Option Grant Program, at each Annual Stockholders
Meeting, beginning with the next Annual Stockholders Meeting, each individual
who (i) is elected or re-elected to serve as a non-employee Board member or (ii)
was appointed as a non-employee Board member since the last Annual Stockholders
Meeting (and whose Board term does not expire at such Meeting) will receive an
option grant to purchase shares of Common Stock. The number of shares subject to
the option will be equal to 15,000 shares for the first year that the optionee
is elected to the Board and 5,000 shares for each additional year served by such
optionee following the automatic option grant. Each option granted pursuant to
the Automatic Option Grant Program will have an exercise price equal to the fair
market value per share of Common Stock on the grant date and will have a maximum
term of 10 years, subject to earlier termination following the optionee's
cessation of Board service. The grant of 15,000 shares will vest in successive
equal monthly installments over forty-eight months of Board service completed by
the optionee measured from the date the optionee is first elected to the Board
of Directors, and the grants of 5,000 will vest at the end of each additional
year of Board service completed by the optionee. In addition, the option shares
will become fully vested upon (i) certain changes in the ownership or control of
the Company or (ii) the death or disability of the optionee while serving as a
Board member. The automatic options may only be exercised to the extent vested.
 
    Payment of the exercise price for the shares of Common Stock subject to
option grants made under the Plan may be made in cash or in shares of Common
Stock valued at fair market value on the exercise date. The optionee may elect
to make payment for the option shares upon exercise through a same-day sale
program, which enables the optionee to purchase the option shares without making
any cash payment. In addition, the Plan Administrator may provide financial
assistance to one or more optionees in the exercise of their outstanding options
by allowing such individuals to deliver a full-recourse, interest-bearing
promissory note in full payment of the exercise price and associated withholding
taxes incurred in connection with such exercise.
 
    In the event that the Company is acquired by merger or asset sale, the
unvested portion of each outstanding option under the Discretionary Option Grant
Program that is not to be assumed by the successor corporation will
automatically vest in full. Similarly, unless the Company assigns the repurchase
rights associated with any unvested shares under the Stock Issuance Program to
the successor corporation, such unvested shares will vest in full. Any
outstanding options assumed by the successor corporation and shares that remain
subject to repurchase rights assigned to the successor corporation will not vest
immediately, but will vest in accordance with their original vesting schedule.
The Plan Administrator will have the authority under the Discretionary Option
Grant and Stock Issuance Programs to grant options and to structure repurchase
rights so that the shares subject to those options or repurchase rights will
automatically vest in the event the individual's service is terminated, whether
involuntarily or through a resignation for good reason, within a specified
period (not to exceed 18 months) following (i) a merger or asset sale in which
those options are assumed or those repurchase rights are assigned, (ii) a
hostile change in control of the Company effected by a successful tender offer
for more than 50% of the outstanding voting stock or by proxy contest for the
election of Board members
 
                                       54
<PAGE>
or (iii) the sale, transfer or disposition of all or substantially all of the
Company's assets (each a "Corporate Transaction"). The Plan Administrator will
also have the discretion to provide for the automatic acceleration of options
and the lapse of any repurchase rights upon (i) a hostile change in control of
the Company effected by a successful tender offer for more than 50% of the
Company's outstanding voting stock or by proxy contest for the election of Board
members or (ii) the termination of the individual's service, whether
involuntarily or through a resignation for good reason, within a specified
period (not to exceed 18 months) following such a hostile change in control. The
unvested portion of the options currently outstanding under the Predecessor Plan
will accelerate and such options will terminate and cease to be exercisable upon
an acquisition of the Company by merger or asset sale, unless those options are
assumed by the acquiring entity. The unvested portion of any options assumed by
the successor corporation will automatically accelerate upon the involuntary
termination of the optionee's service within 18 months following the occurrence
of a Corporate Transaction in which the options are assumed or replaced by the
successor corporation.
 
    Stock appreciation rights may be issued in tandem with option grants made
under the Discretionary Option Grant Program. The holders of these rights will
have the opportunity to elect between the exercise of their outstanding stock
options for shares of Common Stock or the surrender of those options for an
appreciation distribution from the Company equal to the excess of (i) the fair
market value of the vested shares of Common Stock subject to the surrendered
option over (ii) the aggregate exercise price payable for such shares. The
appreciation distribution may be made in cash or in shares of Common Stock.
There are currently no outstanding stock appreciation rights.
 
    The Plan Administrator has the authority to effect the cancellation of
outstanding options under the Discretionary Option Grant Program (including
options incorporated from the Predecessor Plan) in return for the grant of new
options for the same or a different number of option shares with an exercise
price per share based upon the fair market value of the Common Stock on the new
grant date.
 
    The Board may amend or modify the Plan at any time. The Plan will terminate
10 years from its effective date unless otherwise terminated by the Board prior
to such date.
 
  EMPLOYEE STOCK PURCHASE PLAN
 
    The Company's Employee Stock Purchase Plan (the "Purchase Plan") was adopted
by the Board on February 19, 1997 and was subsequently approved by the
stockholders on February 20, 1997. The Purchase Plan is designed to allow
eligible employees of the Company to purchase shares of Common Stock, at
semi-annual intervals, through periodic payroll deductions under the Purchase
Plan. A reserve of 200,000 shares of Common Stock has been established for this
purpose.
 
    The Purchase Plan will be implemented in a series of successive offering
periods, each with a maximum duration of 24 months. However, the initial
offering period will begin on the day the underwriting agreements are executed
in connection with the Offering and will end on the last business day in March
1999.
 
    Individuals who are eligible employees on the start date of any offering
period may enter the Purchase Plan on that start date or on any subsequent
semi-annual entry date (April 1 or October 1 each year). Individuals who become
eligible employees after the start date of the offering period may join the
Purchase Plan on any subsequent semi-annual entry date within that period.
 
    Payroll deductions may not exceed 10% of the participant's base salary for
each semi-annual period of participation, and the accumulated payroll deductions
will be applied to the purchase of shares on the participant's behalf on each
semi-annual purchase date (the last business day of March and September each
year, with the first purchase date to occur on the last business day of
September 1997) at a purchase price per share not less than 85% of the LOWER of
(i) the fair market value of the Common Stock on the participant's entry date
into the offering period or (ii) the fair market value of the Common Stock
 
                                       55
<PAGE>
on the semi-annual purchase date. Should the fair market value of the Common
Stock on any semi-annual purchase date be less than the fair market value of the
Common Stock on the first day of the offering period, then the current offering
period will automatically end and a new 24-month offering period will begin,
based on the lower fair market value.
 
LIMITATIONS ON LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company's Second Restated Certificate of Incorporation eliminates,
subject to certain exceptions, directors' personal liability to the Company or
its stockholders for monetary damages for breaches of fiduciary duties. The
Second Restated Certificate of Incorporation does not, however, eliminate or
limit the personal liability of a director for (i) any breach of the director's
duty of loyalty to the Company or its stockholders, (ii) acts or omissions not
in good faith or which involve intentional misconduct or a knowing violation of
law, (iii) unlawful payments of dividends or unlawful stock repurchases or
redemptions as provided in Section 174 of the Delaware General Corporation Law
or (iv) any transaction from which the director derived an improper personal
benefit.
 
    The Company's Restated Bylaws provide that the Company shall indemnify its
directors and executive officers to the fullest extent permitted under the
Delaware General Corporation Law and may indemnify its other officers, employees
and other agents as set forth in the Delaware General Corporation Law. In
addition, the Company has entered into indemnification agreements with its
directors and officers. The indemnification agreements contain provisions that
require the Company, among other things, to indemnify its directors and
executive officers against certain liabilities (other than liabilities arising
from intentional or knowing and culpable violations of law) that may arise by
reason of their status or service as directors or executive officers of the
Company or other entities to which they provide service at the request of the
Company and to advance expenses they may incur as a result of any proceeding
against them as to which they could be indemnified. The Company believes that
these provisions and agreements are necessary to attract and retain qualified
directors and officers. The Company has obtained an insurance policy covering
directors and officers for claims that such directors and officers may otherwise
be required to pay or for which the Company is required to indemnify them,
subject to certain exclusions.

    In July 1995, the Company raised approximately $8 million from various
venture capital funds, including funds which are principal stockholders of the
Company and/or are affiliated with directors of the Company, in a private
placement of its Series A-1 Preferred Stock. As a result of this financing, the
Company repaid its indebtedness to Kaiser Aerospace by permitting Kaiser
Aerospace to cancel $2.4 million of indebtedness owed by the Company as payment
for shares of Series A-1 Preferred Stock and by repaying an additional $3
million debt owed to Kaiser Aerospace with funds received pursuant to the
private placement transaction. As part of this Series A-1 Preferred Stock
financing, the Company also acquired Oktas, Inc. as its wholly-owned subsidiary
pursuant to the receipt of all of the outstanding shares of Oktas, Inc. as
payment for shares of Series A-1 Preferred Stock received by Mr. Koichiro Hori,
the founder and sole shareholder of Oktas, Inc. and currently an executive
officer of the Company.
 
    In September 1995, the Company purchased substantially all of the assets of
AST, which was engaged in the business of designing, developing, marketing and
supporting stereoscopic endoscopes. The purchase price for such assets consisted
of $25,000 and 154,581 shares of Series A-3 Preferred Stock of Vista Medical,
which is non-voting stock. Pursuant to its rights under the purchase
 
                                       57
<PAGE>
agreement, AST assigned its rights to receive the consideration payable by Vista
Medical to various venture capital funds, including funds which are principal
stockholders of the Company and/or are affiliated with directors of the Company.
 
    In September 1994, the Company entered into a license agreement with Allen
Newman, currently an executive officer of the Company, under which Mr. Newman
granted the Company an exclusive license to use the Newman Technology. In
December 1996, the Company and Urohealth entered into a license agreement under
which the Company exclusively sublicensed the Newman Technology to Urohealth for
use in gynecology, urology and general surgery on a worldwide basis. In
connection with the license agreement, the parties entered into a consulting
agreement whereby Vista Medical agreed to use its reasonable efforts to provide
the services of Mr. Newman as a consultant. The Newman license agreement was
amended in December 1996 to permit the Company to sublicense the Newman
Technology to Urohealth. In connection with the amendment of the Newman license
agreement, the Company paid Mr. Newman $200,000 and agreed to pay Mr. Newman a
percentage of the royalties received from Urohealth. Previously, the Company
made advance royalty payments of $37,500 to Mr. Newman in connection with the
execution of the initial license agreement.
 
    In November 1996, Vista Medical and Medtronic entered into a strategic
alliance providing for the distribution and co-promotion of the Vista Systems.
In connection with entering into a co-promotion agreement, Medtronic made a $10
million equity investment in the Company.
 
    In May 1996, the Company loaned certain officers of the Company an aggregate
of $63,750 in connection with the exercise of certain stock options by such
officers.
 
    All of the Company's officers are employed by the Company at will. The
Company has entered into indemnification agreements with each of its directors
and executive officers. See "Management -- Limitations on Liability and
Indemnification Matters."
 
    The Company believes that all of the transactions set forth above were made
on terms no less favorable to the Company than could have been obtained from
unaffiliated third parties. The Company expects that all future transactions
between the Company and its officers, directors and principal stockholders and
their affiliates will be approved in accordance with the Delaware General
Corporation Law by a majority of the Board, as well as by a majority of the
independent and disinterested directors of the Board, and will be on terms no
less favorable to the Company than could be obtained from unaffiliated third
parties.

                          DESCRIPTION OF CAPITAL STOCK
 
    Upon completion of the Offering, the Company will be authorized to issue
35,000,000 shares of Common Stock, $.01 par value per share, of which 12,718,903
shares will be issued and outstanding, and 5,000,000 shares of undesignated
Preferred Stock, $.01 par value per share, of which no shares will be issued and
outstanding.
 
COMMON STOCK
 
    At February 28, 1997, there were 9,294,528 shares of Common Stock
outstanding and held of record by approximately 44 stockholders. The holders of
Common Stock are entitled to one vote for each share held of record on all
matters submitted to a vote of the stockholders. Subject to preferences that may
be applicable to any outstanding shares of Preferred Stock, holders of Common
Stock are entitled to receive ratably such dividends as may be declared by the
Board out of funds legally available. See "Dividend Policy." All outstanding
shares of Common Stock are fully paid and nonassessable.
 
PREFERRED STOCK
 
    After completion of the Offering, the Board will have the authority, without
further action by the stockholders, to issue up to 5,000,000 shares of Preferred
Stock in one or more series and to fix the rights, priorities, preferences,
qualifications, limitations and restrictions, including dividend rights,
conversion rights, voting rights, terms of redemption, terms of sinking funds,
liquidation preferences and the number of shares constituting any series or the
designation of such series, which could decrease the amount of earnings and
assets available for distribution to holders of Common Stock or adversely affect
the rights and powers, including voting rights, of the holders of the Common
Stock. The issuance of Preferred Stock could have the effect of delaying or
preventing a change in control of the Company or make removal of management more
difficult. Additionally, the issuance of Preferred Stock may have the effect of
decreasing the market price of the Common Stock and may adversely affect the
voting and other rights of the holders of Common Stock.
 
WARRANTS
 
    In February 1997, in connection with the agreement with Heartport, the
Company issued to Heartport a warrant to purchase up to 100,000 shares of Common
Stock, exercisable at any time after the closing of this Offering and prior to
March 31, 2001 at a price per share equal to the initial public offering price.
The warrant contains provisions for the adjustment of the exercise price and the
aggregate number of shares issuable upon exercise of the warrant under certain
circumstances, including stock dividends, stock splits, reorganizations,
reclassifications or consolidations. The holder of the warrant is entitled to
certain registration rights with respect to the Common Stock issued or issuable
upon exercise thereof. See "-- Registration Rights."
 
REGISTRATION RIGHTS
 
    The holders of approximately 8,780,679 shares of Common Stock or their
permitted transferees (the "Holders") are entitled to certain rights with
respect to the registration of such shares under the Securities Act. Under the
terms of agreements between the Company and such Holders, if the Company
proposes to register any of its securities under the Securities Act for its own
account, such Holders are entitled to notice of such registration and are
entitled to include shares of such Common Stock therein, provided, among other
conditions, that the underwriters of any such offering have the right to limit
the number of shares included in such registration. In addition, Holders of at
least 40% of approximately 8,780,679 shares of Common Stock with demand
registration rights may require the Company to prepare and file a registration
statement under the Securities Act with respect to the shares entitled to demand
registration rights, and the Company is required to use its best efforts to
effect such registration,
 
                                       61
<PAGE>
subject to certain conditions and limitations. The Company is not obligated to
effect more than two of these stockholder-initiated registrations nor to effect
such a registration within 90 days following an offering of the Company's
securities, including the Offering made hereby. The Holders of approximately
8,780,679 shares of Common Stock may also request the Company to register such
shares on Form S-3 provided the shares registered have an aggregate market value
of at least $7.5 million. The Company is not obligated to effect more than two
of these registrations pursuant to Form S-3 per year. Generally, the Company is
required to bear the expense of all such registrations. The registration rights
of the Holders expire on the seventh anniversary of the effective date of this
Offering or, if earlier, for an individual Holder, at such time after the
Offering as all shares held by such Holder can be sold within any three-month
period pursuant to Rule 144. All rights of the Holders to require registration
of the resale of their shares in connection with this Offering have been waived.
 
POSSIBLE ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER PROVISIONS
 
  SECOND RESTATED CERTIFICATE OF INCORPORATION AND RESTATED BYLAWS
 
    The Company's Second Restated Certificate of Incorporation authorizes the
Board to establish one or more series of undesignated Preferred Stock, the terms
of which can be determined by the Board at the time of issuance. See "--
Preferred Stock." The Second Restated Certificate of Incorporation also provides
that all stockholder action must be effected at a duly called meeting of
stockholders and not by a consent in writing. The Company's Restated Bylaws
provide that the Company's Board will be classified into three classes of
directors beginning at the next annual meeting of stockholders. See "Management
- -- Executive Officers and Directors." In addition, the Restated Bylaws do not
permit stockholders of the Company to call a special meeting of stockholders;
only the Company's Chief Executive Officer, President, Chairman of the Board or
a majority of the Board are permitted to call a special meeting of stockholders.
The Restated Bylaws also require that stockholders give advance notice to the
Company's secretary of any nominations for director or other business to be
brought by stockholders at any stockholders' meeting and require a supermajority
vote of members of the Board and/or stockholders to amend certain Bylaw
provisions. These provisions of the Second Restated Certificate of Incorporation
and the Restated Bylaws could discourage potential acquisition proposals and
could delay or prevent a change in control of the Company. Such provisions may
also have the effect of preventing changes in the management of the Company.
 
  DELAWARE TAKEOVER STATUTE
 
    The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203") which, subject to certain exceptions, prohibits a Delaware
corporation from engaging in any business combination with any interested
stockholder (defined as any person or entity that is the beneficial owner of at
least 15% of a corporation's voting stock) for a period of three years following
the time that such stockholder became an interested stockholder, unless: (i)
prior to such time, the board of directors of the corporation approved either
the business combination or the transaction that resulted in the stockholder's
becoming an interested stockholder; (ii) upon consummation of the transaction
that resulted in the stockholder's becoming an interested stockholder, the
interested stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding, for purposes of
determining the number of shares outstanding, those shares owned (x) by persons
who are directors and also officers and (y) by employee stock plans in which
employee participants do not have the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer;
or (iii) at or subsequent to such time, the business combination is approved by
the Board and authorized at an annual or special meeting of stockholders, and
not by written consent, by the affirmative vote of at least two-thirds of the
outstanding voting stock that is not owned by the interested stockholder.
 
                                       62
<PAGE>
    Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, lease, exchange, mortgage, transfer, pledge or other disposition involving
the interested stockholder and 10% or more of the assets of the corporation;
(iii) subject to certain exceptions, any transaction which results in the
issuance or transfer by the corporation of any stock of the corporation to the
interested stockholder; (iv) any transaction involving the corporation that has
the effect of increasing the proportionate share of the stock of any class or
series of the corporation beneficially owned by the interested stockholder; or
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or through
the corporation.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is Boston EquiServe.

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of this Offering, the Company will have 12,718,903 shares of
Common Stock outstanding (assuming no exercise of options or other convertible
securities or issuances of Common Stock pursuant to the 1997 Employee Stock
Purchase Plan subsequent to December 31, 1996). The 3,500,000 shares sold in
this Offering will be freely tradeable without restriction or further
registration under the Securities Act, except that any shares purchased by
"affiliates" of the Company, as that term is defined in Rule 144 under the
Securities Act ("Affiliates"), may generally be sold only in compliance with
certain of the limitations of Rule 144 described below.
 
    The remaining approximately 9,219,000 shares of Common Stock are deemed
"Restricted Shares" under Rule 144. Of the Restricted Shares, approximately 750
shares may be eligible for sale in the public market immediately after this
offering pursuant to Rule 144(k) under the Securities Act. Approximately
6,800,000 additional Restricted Shares may be eligible for sale in the public
market in accordance with Rule 144 or Rule 701 under the Securities Act
beginning 90 days after the date of this Prospectus. The holders of
approximately 6,730,000 of these Restricted Shares have agreed not to sell or
otherwise dispose of any of their shares for a period of 180 days after the date
of this Prospectus without the prior written consent of Goldman, Sachs & Co.
Goldman, Sachs & Co. may, in its sole discretion, and at any time without
notice, release all or any portion of the securities subject to lock-up
agreements.
 
    Upon expiration of the lock-up agreements 180 days after the date of this
Prospectus, approximately 7,571,000 shares of Common Stock (including shares
issued or issuable upon the exercise of vested options and warrants outstanding
as of February 28, 1997) will become available for sale in the public market;
the remaining 1,600,000 shares will become eligible for sale under Rule 144 at
various dates thereafter as the holding period provisions of Rule 144 are
satisfied.
 
    In general, under Rule 144 as recently amended, effective April 29, 1997,
beginning approximately 90 days after the effective date of the Registration
Statement of which this Prospectus is a part, a stockholder, including an
Affiliate, who has beneficially owned his or her restricted securities (as that
term is defined in Rule 144) for at least one year from the later of the date
such securities were acquired from the Company or (if applicable) the date they
were acquired from an Affiliate is entitled to sell, within any three-month
period, a number of such shares that does not exceed the greater of 1% of the
then outstanding shares of Common Stock (approximately 127,000 immediately after
the Offering) or the average weekly trading volume in the Common Stock during
the four calendar weeks preceding the date on which notice of such sale was
filed under Rule 144, provided certain requirements concerning availability of
public information, manner of sale and notice of sale are satisfied. In
addition, under Rule 144(k), if a period of at least two years has elapsed
between the later of the date restricted securities were acquired from the
Company or (if applicable) the date they were acquired from an Affiliate of the
Company, a stockholder who is not an Affiliate of the Company at the time of
sale and has not been an Affiliate of the Company for at least three months
prior to the sale is entitled to sell the shares immediately without compliance
with the foregoing requirements under Rule 144.
 
    Securities issued in reliance on Rule 701 (such as shares of Common Stock
that may be acquired pursuant to the exercise of certain options granted prior
to this Offering) are also restricted securities and, beginning 90 days after
the date of this Prospectus, may be sold by stockholders other than an Affiliate
of the Company subject only to the manner of sale provisions of Rule 144 and by
an Affiliate under Rule 144 without compliance with its one-year holding period
requirement.
 
    Prior to this Offering, there has been no public market for the Common
Stock. No prediction can be made as to the effect, if any, that market sales of
shares or the availability of shares for sale will have on the market price of
the Common Stock prevailing from time to time. The Company is unable to estimate
the number of shares that may be sold in the public market pursuant to Rule 144,
since this will depend on the market price of the Common Stock, the personal
circumstances of the sellers and other factors. Nevertheless, sales of
significant amounts of the Common Stock of the Company in the public market
 
                                       64
<PAGE>
could adversely affect the market price of the Common Stock and could impair the
Company's ability to raise capital through an offering of its equity securities.
 
    In addition, the Company intends to register on the effective date of this
Offering a total of 2,820,000 shares of Common Stock subject to outstanding
options or reserved for issuance under the Company's 1997 Stock Option/Stock
Issuance Plan and 200,000 shares of Common Stock reserved for issuance under its
1997 Employee Stock Purchase Plan. Further, upon expiration of such lock-up
agreements, holders of approximately 8,780,679 shares of Common Stock will be
entitled to certain registration rights with respect to such shares. If such
holders, by exercising their registration rights, cause a large number of shares
to be registered and sold in the public market, such sales could have a material
adverse effect on the market price for the Common Stock.
 
                                 LEGAL MATTERS
 
    The validity of the Common Stock offered hereby will be passed upon for the
Company by Brobeck, Phleger & Harrison LLP, San Diego, California. Partners of
such firm own 7,500 shares of the Common Stock. Certain legal matters will be
passed upon for the Underwriters by McDermott, Will & Emery.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Vista Medical Technologies, Inc.
 
    We have audited the accompanying consolidated balance sheets of Vista
Medical Technologies, Inc. as of December 31, 1995 and 1996 and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended December 31, 1996. 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 in accordance with generally accepted auditing
standards. Those standards 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. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Vista Medical Technologies, Inc. at December 31, 1995 and 1996 and the results
of its consolidated operations and its cash flows for each of the three years in

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1996
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  ORGANIZATION AND BUSINESS ACTIVITY
 
    Vista Medical Technologies, Inc. ("the Company") was founded in July 1993 as
a wholly-owned subsidiary of Kaiser Aerospace and Electronics Corporation
("Kaiser Aerospace") to develop an advanced technology business concentrated on
visualization products for minimally invasive surgery.
 
  BASIS OF PRESENTATION
 
    The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary, Oktas, Inc. In 1993, the Company acquired a 65%
interest in a partnership established to perform further research and
development related to certain of the Company's technology. This partnership is
included in the consolidated financial statements and because the Company
provided all the financial resources to the partnership, the Company has
recorded all losses in excess of the minority partners original contribution. In
1995, the minority partner, Oktas, Inc., was acquired by issuing shares of
Series A convertible preferred stock. On December 31, 1996, the partnership was
dissolved. The Company charged the $350,000 value of the preferred stock to
expense as acquired research and development. Significant intercompany accounts
and transactions have been eliminated.
 
  USE OF ESTIMATES
 
    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
disclosures made in the accompanying notes to the consolidated financial
statements. Actual results could differ from those estimates.
 
  REVENUE RECOGNITION
 
    Revenue is recognized upon shipment of product.
 
  CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
    Cash equivalents and short-term investments consist of money market funds
and a certificate of deposit. The Company considers all highly liquid
investments with maturities when purchased of three months or less to be cash
equivalents. The Company evaluates the financial strength of institutions at
which significant investments are made and believes the related credit risk is
limited to an acceptable level.
 
    The Company has adopted Statement of Financial Accounting Standards No. 115,
"Accounting for Certain Investments in Debt and Equity Securities," and has
classified its cash equivalents and short-term investments as available-for-sale
in accordance with that standard. Available-for-sale securities are carried at
fair value, with unrealized gains and losses, net of tax, reported in a separate
component of stockholders' equity. At December 31, 1996, the cost of cash
equivalents and short-term investments was equal to estimated fair value.
Accordingly, there were no unrealized gains or losses.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                               DECEMBER 31, 1996
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  CONCENTRATION OF CREDIT RISK
 
    The Company provides credit, in the normal course of business, to commercial
entities that meet specified credit requirements. The Company's principal
customers consist of original equipment manufacturers in the United States and
Asia. The Company provides for losses from uncollectable accounts and such
losses have not exceeded management's expectations.
 
  INVENTORIES
 
    Inventories are stated at lower of cost (determined on a first-in, first-out
basis) or market.
 
  PROPERTY AND EQUIPMENT
 
    Property and equipment is stated at cost. The Company provides for
depreciation on property and equipment using the straight-line method over the
estimated useful lives of the assets, generally five to seven years. Marketing
demonstration equipment is amortized over a one-year useful life.
 
  PATENTS
 
    Capitalized patent costs are amortized over the lesser of the remaining
useful life of the related technology or the remaining patent life, commencing
on the date the patent is issued. The Company reviews its patents for impairment
on an annual basis or whenever events or changes in circumstances indicate that
the carrying value of the asset would not be recoverable. If the sum of expected
future net cash flows of an individual asset would be less than the carrying
amount of the asset, an impairment loss would be recognized.
 
  STOCK OPTIONS
 
    In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, ACCOUNTING FOR STOCK-BASED COMPENSATION, which is effective for the year
ending December 31, 1996. SFAS No. 123 allows companies to either account for
stock-based compensation under the new provisions of SFAS No. 123 or under the
provisions of Accounting Principles Opinion No. 25, ACCOUNTING FOR STOCK ISSUED
TO EMPLOYEES ("APB 25"), but requires pro forma disclosure in the footnotes to
the financial statements as if the measurement provisions of SFAS No. 123 had
been adopted. The Company has continued accounting for its stock-based
compensation in accordance with the provisions of APB 25.
 
  ASSET IMPAIRMENT
 
    In March 1995, the FASB issued SFAS No.121, "ACCOUNTING FOR THE IMPAIRMENT
OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF," which
requires impairment losses to be recorded on long-lived assets used in
operations when indicators of impairment are present and the estimated
undiscounted cash flows to be generated by those assets are less than the
assets' carrying amount. SFAS 121 also addresses the accounting for long-lived
assets that are expected to be disposed of. The Company adopted the provisions
of SFAS No. 121 effective January 1, 1996. There was no effect of such adoption
on the Company's financial position or results of operations.

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
  NET LOSS PER SHARE
 
    Historical net loss per share is calculated using the weighted average
number of common shares outstanding and common stock equivalents outstanding
during the periods presented. Common equivalent shares result from stock options
and preferred stock. For loss periods, common equivalent shares are excluded
from the computation as their effect would be antidilutive, except that the
Securities and Exchange Commission requires common and common share equivalents
issued during the twelve-month period prior to the initial filing of a proposed
public offering, to be included in the calculation as if they were outstanding
for all periods presented (using the treasury stock method and the assumed
initial public offering price).
 
    Historical net loss per share information is as follows:

    PRO FORMA NET LOSS PER SHARE AND UNAUDITED PRO FORMA STOCKHOLDERS' EQUITY
 
    Pro forma net loss per share has been computed as described above and also
gives effect to the conversion of the preferred stock, which will automatically
convert to common stock immediately prior to the completion of the Company's
initial public offering, using the as converted method from the original date of
issuance.
 
    If the offering contemplated by the Prospectus is consummated, all of the
convertible preferred stock outstanding as of the closing date will
automatically be converted into 8,680,679 shares of common stock. Unaudited pro
forma stockholders' equity at December 31, 1996, as adjusted for the conversion
of preferred stock, is disclosed in the accompanying balance sheet.

  STOCK OPTION PLAN
 
    The Company has reserved 2,015,610 shares of common stock under the 1995
Stock Option Plan ("the 1995 Plan") for issuance to eligible employees,
officers, directors, advisors and consultants. The 1995 Plan provides for the
grant of incentive and nonstatutory stock options. Terms of the stock option
agreements, including vesting requirements, are determined by the Board of
Directors, subject to the provisions of the 1995 Plan. Options granted by the
Company generally vest over four to five years and are exercisable from the date
of grant for a period of ten years. The exercise price of the incentive stock
options must equal at least the fair market value of the stock on the date of
grant. The exercise price of nonstatutory stock options must equal at least 85%
of the fair market value of the stock on the date of grant. The Company has the
option, in the event of termination of employment to repurchase unvested shares
issued under the 1995 Plan at the original issue price.
 
    The Company recorded $2,508,811 of deferred compensation for options granted
during the year ended December 31, 1996, representing the difference between the
option exercise price and the deemed value for financial statement presentation
purposes. The Company is amortizing the deferred compensation over the vesting
period of the options. The Company recorded $447,262 of compensation expense
during the year ended December 31, 1996.
 
    The Company will record $743,000 of additional deferred compensation
representing the difference between the option exercise price and the deemed
value for financial statement presentation purposes for stock options granted in
January and February 1997.

    As the Company was part of a consolidated group prior to the change in
ownership in July 1995, all tax loss and tax credit carryforwards up to the date
of change in ownership have been reported by the previous consolidated group.
All tax loss and tax credit carryforwards reflected in the accompanying
financial statements reflect activity only for the seventeen-month period ending
December 31, 1996.
 
    At December 31, 1996, the Company has federal and state tax net loss
carryforwards of approximately $8,494,000 and $5,146,000, respectively. The
federal and state tax loss carryforwards will expire in 2010 and 2000,
respectively, unless previously utilized. The Company also has federal and state
research tax credit carryforwards of approximately $135,000 and $143,000
respectively, which will expire in 2010 unless previously utilized.
 
    In accordance with Sections 382 and 383 of the Internal Revenue Code, a
change in ownership of greater than 50 percent of a corporation within a
three-year period will place an annual limitation on the Company's ability to
utilize its existing tax loss and tax credit carryforwards.
 
8. TRANSACTIONS WITH RELATED PARTIES

full with cash payments of $3,004,000 and the issuance of Series A convertible
preferred stock valued at $2,375,000.
 
    The Company has a technology strategic alliance and a manufacturing supply

manufacturing of certain of the Company's proprietary products. Under the terms
of the agreements, which expire in July 1998, Kaiser Aerospace will provide
development and consulting services and a minimum of 75% of certain of the
Company's product requirements provided certain competitive criteria are met.
Payments made to Kaiser under these arrangements totaled approximately $292,000
and $1,205,000 for the years ending December 31,

    Under the terms and conditions of the Underwriting Agreement, the
Underwriters are committed to take and pay for all of the shares offered hereby,
if any are taken.
 
    The Underwriters propose to offer the shares of Common Stock in part
directly to the public at the initial public offering price set forth on the
cover page of this Prospectus and in part to certain securities dealers at such
price less a concession of $    per share. The Underwriters may allow, and such
dealers may reallow, a concession not in excess of $    per share to certain
brokers and dealers. After the shares of Common Stock are released for sale to
the public, the offering price and other selling terms may from time to time be
varied by the representatives.
 
    The Company has granted the Underwriters an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of 525,000
additional shares of Common Stock solely to cover over-allotments, if any. If
the Underwriters exercise their over-allotment option, the Underwriters have
severally agreed, subject to certain conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by each of
them, as shown in the foregoing table, bears to the 3,500,000 shares of Common
Stock offered in the Offering.
 
    The Company has agreed that it will not, during the period beginning from
the date of this Prospectus and continuing to and including the date 180 days
after the date of this Prospectus, offer, sell, contract to sell or otherwise
dispose of any securities of the Company (other than pursuant to employee stock
option plans existing, or on the conversion or exchange of convertible or
exchangeable securities outstanding, on the date of this Prospectus) which are
substantially similar to the shares of Common Stock or which are convertible
into or exchangeable for securities which are substantially similar to the
shares of Common Stock, without the prior written consent of Goldman, Sachs &
Co., except for the shares of Common Stock offered in connection with the
Offering. Certain directors, officers and stockholders of the Company have
agreed not to offer, sell, contract to sell or otherwise dispose of any of such
securities held thereby for a period of 180 days after the date of this
Prospectus without the prior written consent of Goldman, Sachs & Co.
 
                                      U-1
<PAGE>
    The representatives of the Underwriters have informed the Company that they
do not expect sales to accounts over which the Underwriters exercise
discretionary authority to exceed 5% of the total number of shares of Common
Stock offered thereby.
 
    Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price will be negotiated among the Company and the
representatives of the Underwriters. Among the factors to be considered in
determining the initial public offering price of the Common Stock, in addition
to prevailing market conditions, will be the Company's historical performance,
estimates of the business potential and earnings prospects of the Company, an
assessment of the Company's management and the consideration of the above
factors in relation to market valuation of companies in related businesses.
 
    During and after the Offering, the Underwriters may purchase and sell Common
Stock in the open market. These transactions may include overallotment and
stabilizing transactions and purchases to cover syndicate short positions
created in connection with the Offering. The Underwriters also may impose a
penalty bid, whereby selling concessions allowed to syndicate members or other
broker-dealers in respect of the Common Stock sold in the Offering for their
account may be reclaimed by the syndicate if such securities are repurchased by
the syndicate in stabilizing or covering transactions. These activities may
stabilize, maintain or otherwise affect the market price of the Common Stock
which may be higher than the price that might otherwise prevail in the open
market. These transactions may be effected in the Nasdaq National Market, the
over-the-counter market, or otherwise, and these activities, if commenced, may
be discontinued at any time.
 
    The Company has applied for quotation of the Common Stock on the Nasdaq
National Market under the symbol "VMTI."
 
    The Company has agreed to indemnify the several Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended.

    Vista Medical believes that the management of information under surgeon
control, is a key component in the development of advanced visualization systems
for minimally invasive microsurgery (MIM). The HMD is designed to facilitate the
display of critical diagnostic and monitoring data integrated in real-time with
the anatomical images generated by the Company's camera systems. This capability
will be enhanced by the recent addition of high speed image-based information
processing and networking software to the Company's technology portfolio.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
    Section 145 of the Delaware General Corporation Law permits indemnification
of officers and directors of the Company under certain conditions and subject to
certain limitations. Section 145 of the Delaware General Corporation Law also
provides that a corporation has the power to purchase and maintain insurance on
behalf of its officers and directors against any liability asserted against such
person and incurred by him or her in such capacity, or arising out of his or her
status as such, whether or not the corporation would have the power to indemnify
him or her against such liability under the provisions of Section 145 of the
Delaware General Corporation Law.
 
    Article VII, Section (1) of the Restated Bylaws of the Company provides that
the Company shall indemnify its directors and executive officers to the fullest
extent not prohibited by the Delaware General Corporation Law. The rights to
indemnity thereunder continue as to a person who has ceased to be a director,
officer, employee or agent and inure to the benefit of the heirs, executors and
administrators of the person. In addition, expenses incurred by a director or
executive officer in defending any civil, criminal, administrative or
investigative action, suit or proceeding by reason of the fact that he or she is
or was a director or officer of the Company (or was serving at the Company's
request as a director or officer of another corporation) shall be paid by the
Company in advance of the final disposition of such action, suit or proceeding
upon receipt of an undertaking by or on behalf of such director or officer to
repay such amount if it shall ultimately be determined that he or she is not
entitled to be indemnified by the Company as authorized by the relevant section
of the Delaware General Corporation Law.
 
    As permitted by Section 102(b)(7) of the Delaware General Corporation Law,
Article V, Section (A) of the Company's Second Restated Certificate of
Incorporation provides that a director of the Company shall not be personally
liable for monetary damages for breach of fiduciary duty as a director, except
for liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith or
acts or omissions that involve intentional misconduct or a knowing violation of

    The Company has entered into indemnification agreements with each of its
directors and executive officers. Generally, the indemnification agreements
attempt to provide the maximum protection permitted by Delaware law as it may be
amended from time to time. Moreover, the indemnification agreements provide for
certain additional indemnification. Under such additional indemnification
provisions, however, an individual will not receive indemnification for
judgments, settlements or expenses if he or she is found liable to the Company
(except to the extent the court determines he or she is fairly and reasonably
entitled to indemnity for expenses), for settlements not approved by the Company
or for settlements and expenses if the settlement is not approved by the court.
The indemnification agreements provide for the Company to advance to the
individual any and all reasonable expenses (including legal fees and expenses)
incurred in investigating or defending any such action, suit or proceeding. In
order to receive an advance of expenses, the individual must submit to the
Company copies of invoices presented to him or her for such expenses. Also, the
individual must repay such advances upon a final judicial decision that he or
she is not entitled to indemnification.
 
    The Company intends to enter into additional indemnification agreements with
each of its directors and executive officers to effectuate these indemnity
provisions and to purchase directors' and officers' liability insurance.
 
    The Underwriting Agreement (Exhibit 1.1 hereto) contains provisions by which
the Underwriters have agreed to indemnify the Company, each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act,
each director of the Company, and each officer of the Company who signs this
Registration Statement, with respect to information furnished in writing by or
on behalf of the Underwriters for use in the Registration Statement.

HealthCom, Inc. and GDE, pursuant to which the Company is obligated to issue
20,833 shares of Common Stock to GDE within ten business days of the close of
this Offering, assuming an initial public offering price of $12.00 per share
(the midpoint of the range set forth on the cover page of this Prospectus).
 
    The sales and issuances of securities in the above transactions were deemed
to be exempt under the Act by virtue of Section 4(2) thereof and/or Regulation D
and Rule 701 promulgated thereunder as transactions not involving any public
offering. The purchasers in each case represented their intention to acquire the
securities for investment only and not with a view to the distribution thereof.
Appropriate legends were affixed to the stock certificates issued in such
transactions. Similar representations of investment intent were obtained and
similar legends imposed in connection with any subsequent transfers of any such
securities. The Company believes that all recipients had adequate access,
through employment or other relationships, to information about the Company to
make an informed investment decision.

ITEM 17.  UNDERTAKINGS.

denominations and registered in such names as required by the Underwriters to

    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the Company
pursuant to the provisions described in Item 14, or otherwise, the Company has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company 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 Company 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 as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
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.
 
    (2) For the purpose of determining any liability under the Securities Act,
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.

in no event earlier than the First Time of Delivery (as defined in Section 4
hereof) or, unless you and the Company otherwise agree in writing, earlier than
two or later than ten business days after the date of such notice.

     (j)  The Company has obtained and delivered to the Underwriters executed
copies of an agreement from each of the executive officers, directors,
stockholders, option holders and warrant holders listed on Schedule 7(j)
attached hereto, substantially to the effect set forth in Subsection 5(f) hereof
in form and substance satisfactory to you;


                                      -14-

<PAGE>

     (k)  The Company shall have complied with the provisions of Subsection 5(c)
hereof with respect to the furnishing of prospectuses on the New York Business
Day next succeeding the date of this Agreement.

     (l)  The Company shall have furnished or caused to be furnished to you at
such Time of Delivery certificates of officers of the Company satisfactory to
you as to the accuracy of the representations and warranties of the Company
herein at and as of such Time of Delivery, as to the performance by the Company
of all of its obligations hereunder to be performed at or prior to such Time of
Delivery, as to the matters set forth in subsections (a) and (e) of this Section
and as to such other matters as you may reasonably request; and

     8. (a) The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the 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 each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; PROVIDED, HOWEVER, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through Goldman, Sachs & Co. expressly for use therein.

     (b)  Each Underwriter will indemnify and hold harmless the Company against
any losses, claims, damages or liabilities to which the Company may become
subject, under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus, the Registration Statement or the Prospectus, or any
amendment or supplement thereto, or arise out of or are based upon the omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in any Preliminary
Prospectus, the Registration Statement or the Prospectus or any such amendment
or supplement in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through Goldman, Sachs & Co.
expressly for use therein; and will reimburse the Company for any legal or other
expenses reasonably incurred by the Company in connection with investigating or
defending any such action or claim as such expenses are incurred.

     (c)  Promptly after receipt by an indemnified party under subsection (a) or
(b) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made


                                      -15-

<PAGE>

against the indemnifying party under such subsection, notify the indemnifying
party in writing of the commencement thereof; but the omission so to notify the
indemnifying party shall not relieve it from any liability which it may have to
any indemnified party otherwise than under such subsection.  In case any such
action 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 therein and, to the extent that it shall wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel satisfactory to such indemnified party (who shall not,
except with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified party
of its election so to assume the defense thereof, the indemnifying party shall
not be liable to such indemnified party under such subsection for any legal
expenses of other counsel or any other expenses, in each case subsequently
incurred by such indemnified party, in connection with the defense thereof other
than reasonable costs of investigation.  No indemnifying party shall, without
the written consent of the indemnified party, effect the settlement or
compromise of, or consent to the entry of any judgment with respect to, any
pending or threatened action or claim in respect of which indemnification or
contribution may be sought hereunder (whether or not the indemnified party is an
actual or potential party to such action or claim) unless such settlement,
compromise or judgment (i) includes an unconditional release of the indemnified
party from all liability arising out of such action or claim and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act, by or on behalf of any indemnified party.

     (d)  If the indemnification provided for in this Section 8 is unavailable
to or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above in respect of any losses, claims, damages or liabilities (or actions
in respect thereof) referred to therein, then each indemnifying party shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages or liabilities (or actions in respect thereof)
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.  If, however, the allocation provided by the immediately
preceding sentence is not permitted by applicable law or if the indemnified
party failed to give the notice required under subsection (c) above, then each
indemnifying party shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only such
relative benefits 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 or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations.  The
relative benefits received by the Company on the one hand and the Underwriters
on the other shall be deemed to be in the same proportion as the total net
proceeds from the offering (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in the table on the cover page of the
Prospectus.  The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or the Underwriters on the other 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 contributions pursuant to this
subsection (d) 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 in this subsection (d).  The amount paid or


                                      -16-

<PAGE>

payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this subsection
(d) shall be deemed to include any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any such
action or claim.  Notwithstanding the provisions of this subsection (d), no
Underwriter shall be required to contribute any amount in excess of the amount
by which the total price at which the Shares underwritten by it and distributed
to the public were offered to the public exceeds the amount of any damages which
such Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.  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.  The Underwriters' obligations in this subsection
(d) to contribute are several in proportion to their respective underwriting
obligations and not joint.

     (e)  The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section 8 shall be in addition to any liability which
the respective Underwriters may otherwise have and shall extend, upon the same
terms and conditions, to each officer and director of the Company (including any
person who, with his or her consent, is named in the Registration Statement as
about to become a director of the Company) and to each person, if any, who
controls the Company within the meaning of the Act.

     9. (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein.  If within thirty-six hours after
such default by any Underwriter you do not arrange for the purchase of such
Shares, then the Company shall be entitled to a further period of thirty-six
hours within which to procure another party or other parties satisfactory to you
to purchase such Shares on such terms.  In the event that, within the respective
prescribed periods, you notify the Company that you have so arranged for the
purchase of such Shares, or the Company notifies you that it has so arranged for
the purchase of such Shares, you or the Company shall have the right to postpone
such Time of Delivery for a period of not more than seven days, in order to
effect whatever changes may thereby be made necessary in the Registration
Statement or the Prospectus, or in any other documents or arrangements, and the
Company agrees to file promptly any amendments to the Registration Statement or
the Prospectus which in your opinion may thereby be made necessary. The term
"Underwriter" as used in this Agreement shall include any person substituted
under this Section with like effect as if such person had originally been a
party to this Agreement with respect to such Shares.

     (b)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased does not exceed one-eleventh of the aggregate number of all
the Shares to be purchased at such Time of Delivery, then the Company shall have
the right to require each non-defaulting Underwriter to purchase the number of
shares which such Underwriter agreed to purchase hereunder at such Time of
Delivery and, in addition, to require each non-defaulting Underwriter to
purchase its pro rata share (based on the number of Shares which such
Underwriter agreed to purchase


                                      -17-

<PAGE>

hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     (c)  If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company as
provided in subsection (a) above, the aggregate number of such Shares which
remains unpurchased exceeds one-eleventh of the aggregate number of all the
Shares to be purchased at such Time of Delivery, or if the Company shall not
exercise the right described in subsection (b) above to require non-defaulting
Underwriters to purchase Shares of a defaulting Underwriter or Underwriters,
then this Agreement (or, with respect to the Second Time of Delivery, the
obligations of the Underwriters to purchase and of the Company to sell the
Optional Shares) shall thereupon terminate, without liability on the part of any
non-defaulting Underwriter or the Company, except for the expenses to be borne
by the Company and the Underwriters as provided in Section 6 hereof and the
indemnity and contribution agreements in Section 8 hereof; but nothing herein
shall relieve a defaulting Underwriter from liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company and the several Underwriters, as set forth
in this Agreement or made by or on behalf of them, respectively, pursuant to
this Agreement, shall remain in full force and effect, regardless of any
investigation (or any statement as to the results thereof) made by or on behalf
of any Underwriter or any controlling person of any Underwriter, or the Company,
or any officer or director or controlling person of the Company, and shall
survive delivery of and payment for the Shares.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
the Company shall not then be under any liability to any Underwriter except as
provided in Sections 6 and 8 hereof; but, if for any other reason, any Shares
are not delivered by or on behalf of the Company as provided herein, the Company
will reimburse the Underwriters through you for all out-of-pocket expenses
approved in writing by you, including fees and disbursements of counsel,
reasonably incurred by the Underwriters in making preparations for the purchase,
sale and delivery of the Shares not so delivered, but the Company shall then be
under no further liability to any Underwriter except as provided in Sections 6
and 8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
Representatives.

     All statements, requests, notices and agreements hereunder shall be in
writing, and if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York  10004, Attention: Registration
Department; and if to the Company shall be delivered or sent by mail to the
address of the Company set forth in the Registration Statement, Attention:
Secretary; provided, however, that any notice to an Underwriter pursuant to
Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile


                                      -18-

<PAGE>

transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire, or telex constituting such Questionnaire, which address will be
supplied to the Company by you upon request.  Any such statements, requests,
notices or agreements shall take effect upon receipt thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and, to the extent provided in Sections 8 and
10 hereof, the officers and directors of the Company and each person who
controls the Company or any Underwriter, and their respective heirs, executors,
administrators, successors and assigns, and no other person shall acquire or
have any right under or by virtue of this Agreement. No purchaser of any of the
Shares from any Underwriter shall be deemed a successor or assign by reason
merely of such purchase.

     14.  Time shall be of the essence of this Agreement.  As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK.

     16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.


     If the foregoing is in accordance with your understanding, please sign and
return to us [one for the Company and each of the Representatives plus one for
each counsel] counterparts hereof, and upon the acceptance hereof by you, on
behalf of each of the Underwriters, this letter and such acceptance hereof shall
constitute a binding agreement between each of the Underwriters and the Company.
It is understood that your acceptance of this letter on behalf of each of the
Underwriters is pursuant to the authority set forth

     Pursuant to Section 7(f) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

        (i)    They are independent certified public accountants with respect to
     the Company within the meaning of the Act and the applicable published
     rules and regulations thereunder;

        (ii)   In their opinion, the financial statements and any supplementary
     financial information and schedules (and, if applicable, financial
     forecasts and/or pro forma financial information) examined by them and
     included in the Prospectus or the Registration Statement comply as to form
     in all material respects with the applicable accounting requirements of the
     Act and the related published rules and regulations thereunder; and, if
     applicable, they have made a review in accordance with standards
     established by the American Institute of Certified Public Accountants of
     the unaudited consolidated interim financial statements, selected financial
     data, pro forma financial information, financial forecasts and/or condensed
     financial statements derived from audited financial statements of the
     Company for the periods specified in such letter, as indicated in their
     reports thereon, copies of which have been separately furnished to the
     representatives of the Underwriters (the "Representatives");

        (iii)  They have made a review in accordance with standards established
     by the American Institute of Certified Public Accountants of the unaudited
     condensed consolidated statements of income, consolidated balance sheets
     and consolidated statements of cash flows included in the Prospectus as
     indicated in their reports thereon copies of which have been separately
     furnished to the Representatives and on the basis of specified procedures
     including inquiries of officials of the Company who have responsibility for
     financial and accounting matters regarding whether the unaudited condensed
     consolidated financial statements referred to in paragraph (vi)(A)(i) below
     comply as to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations,
     nothing came to their attention that cause them to believe that the
     unaudited condensed consolidated financial statements do not comply as to
     form in all material respects with the applicable accounting requirements
     of the Act and the related published rules and regulations;

        (iv)   The unaudited selected financial information with respect to the
     consolidated results of operations and financial position of the Company
     and its subsidiaries for the three most recent fiscal years included in the
     Prospectus agrees with the corresponding amounts (after restatements where
     applicable) in the audited consolidated financial statements for such three
     fiscal years;

        (v)    They have compared the information in the Prospectus under
     selected captions with the disclosure requirements of Regulation S-K and on
     the basis of limited procedures specified in such letter nothing came to
     their attention as a result of the foregoing procedures that caused them to
     believe that this information does not conform in all material respects
     with the disclosure requirements of Items 301, 302, 402 and 503(d),
     respectively, of Regulation
     S-K;


                                      -22-

<PAGE>

        (vi)   On the basis of limited procedures, not constituting an
     examination in accordance with generally accepted auditing standards,
     consisting of a reading of the unaudited financial statements and other
     information referred to below, a reading of the latest available interim
     financial statements of the Company and its subsidiaries, inspection of the
     minute books of the Company since the date of the latest audited financial
     statements included in the Prospectus, inquiries of officials of the
     Company responsible for financial and accounting matters and such other
     inquiries and procedures as may be specified in such letter, nothing came
     to their attention that caused them to believe that:

          (A)  any unaudited income statement data and balance sheet items
          included in the Prospectus do not agree with the corresponding items
          in the unaudited consolidated financial statements from which such
          data and items were derived, and any such unaudited data and items
          were not determined on a basis substantially consistent with the basis
          for the corresponding amounts in the audited consolidated financial
          statements included in the Prospectus;

          (B)  the unaudited financial statements which were not included in the
          Prospectus but from which were derived any unaudited condensed
          financial statements referred to in Clause (A) and any unaudited
          income statement data and balance sheet items included in the
          Prospectus and referred to in Clause (A) were not determined on a
          basis substantially consistent with the basis for the audited
          consolidated financial statements included in the Prospectus;

          (C)  any unaudited pro forma consolidated condensed financial
          statements included in the Prospectus do not comply as to form in all
          material respects with the applicable accounting requirements of the
          Act and the published rules and regulations thereunder or the pro
          forma adjustments have not been properly applied to the historical
          amounts in the compilation of those statements;

          (D)  as of a specified date not more than five days prior to the date
          of such letter, there have been any changes in the capital stock
          (other than issuances of capital stock upon exercise of options and
          stock appreciation rights, upon earn-outs of performance shares and
          upon conversions of convertible securities, in each case which were
          outstanding on the date of the latest financial statements included in
          the Prospectus) or any increase in the long-term debt of the Company
          or any decreases in net current assets or stockholders= equity or
          other items specified by the Representatives, or any increases in any
          items specified by the Representatives, in each case as compared with
          amounts shown in the latest balance sheet included in the Prospectus,
          except in each case for changes, increases or decreases which the
          Prospectus discloses have occurred or may occur or which are described
          in such letter; and

          (E)  for the period from the date of the latest financial statements
          included in the Prospectus to the specified date referred to in Clause
          (D) there were any decreases in net revenues or operating profit or
          the total or per share amounts of net income or other items specified
          by the Representatives, or any increases in any items specified by the
          Representatives, in each case as compared with the comparable period
          of the preceding year and with any other period of corresponding
          length specified by the Representatives, except in each case for
          decreases or increases which the Prospectus discloses have occurred or
          may occur or which are described in such letter; and

       (vii)   In addition to the examination referred to in their report(s)
     included in the Prospectus and the limited procedures, inspection of minute
     books, inquiries and other procedures referred to in paragraphs (iii) and
     (vi) above, they have carried out certain specified procedures, not
     constituting an examination in accordance with generally accepted auditing
     standards, with respect to certain amounts, percentages and financial
     information specified by the Representatives, which are derived from the
     general accounting records of the Company and its subsidiaries, which
     appear in the Prospectus, or in Part II of, or in exhibits and schedules
     to, the Registration Statement specified by the Representatives, and have
     compared certain of such amounts, percentages and financial information
     with the accounting records of the Company and its subsidiaries and have
     found them to be in agreement.

with the sale of __________ shares of common stock of the Company, par value
$.01 per share, pursuant to a Registration Statement on Form S-1.  This opinion
is rendered to you pursuant to Section 7(g) of the Underwriting Agreement, dated

counsel for the Company, that:

     A.   The Company owns or possesses adequate patents, patent licenses,
licenses or other rights to use all trademarks, service marks, trade names,
service names, copyrights, mask works, technology, know-how and other
proprietary intellectual property rights ("Intellectual Property") necessary to

described in the Registration Statement and the Prospectus, and, except as
described in the Registration Statement and the Prospectus, the Company has not
received any notice of infringement of or conflict with, and does not otherwise
know of any basis for, notice of any such infringement of or conflict with,
asserted rights of others;

     (ii)   Except as set forth in Schedule B to this letter or as described in
the Registration Statement and the Prospectus, insofar as the Relevant Patent
Matters are concerned, the Company's discoveries, inventions, products or
processes referred to in the Registration Statement and the Prospectus do not,
to my knowledge, infringe or conflict with any right which is the subject of a
patent known to the Company, which infringement or conflict could result in any
material adverse effect upon the Company's business, financial condition and
results of operations; and

the sub-heading "Business--Patents and Proprietary Rights" refer to our opinions
on matters of law or purport to summarize the status of litigation or the

respect of the Relevant Patent Matters, such statements (A) have been prepared
or reviewed by me and accurately reflect the status of any such litigation, the
provisions purported to be summarized and any such opinions of ours, and (B) are
correct and complete.

     In connection with the opinion expressed in paragraph (i), we have relied,

Gentlemen:

     We have acted as patent counsel to Harry R. McKinley ("McKinley") and
McKinley Optics, Inc. ("McKinley Optics") with respect to the patent matters
reflected on Schedule A attached hereto (the "Relevant Patent Matters") and with
respect to the licensing agreements reflected on Schedule B hereto (the

of McKinley and McKinley Optics pursuant to Section 7(g) of the Underwriting
Agreement, dated March ____, 1997, between you and the Vista Medical
Technologies, Inc. ("the Company"), entered into in connection with the sale of
_________ shares of common stock of the Company, par value $.01 per share,
pursuant to a Registration Statement on Form S-1. .  It is our opinion, as
intellectual property counsel for McKinley, that:

     (i)    Each of the Relevant License Agreements is in full force and effect
and constitutes a legal, valid and binding obligation of each of McKinley Optics
and McKinley, enforceable in accordance with its terms against each of them,
subject to the effect of (i) bankruptcy, insolvency, reorganization, moratorium
and other similar laws now or hereafter in effect affecting creditors' rights
generally, and (ii) general principles of equity, including, without limitation,
concepts of materiality, reasonableness, public policy, good faith and fair
dealing (regardless of whether considered in a proceeding in equity or at law).

     (ii)   Each of McKinley and McKinley Optics owns certain patents,
technology and know-how, and other proprietary intellectual property rights
("Intellectual Property") as described in the Relevant License Agreements and on
Schedule A hereto, and neither McKinley nor McKinley Optics has received any
notice of infringement of or conflict with, and does not otherwise know of any
basis for, notice of any such infringement of or conflict with, asserted rights
of others regarding such Intellectual Property;

     (iii)  The Company is the sole and exclusive licensee of the technology set
forth in Appendix A to the License Agreement (as defined on Schedule B) and no
other person or entity has been granted any rights in, to or under such
technology.

     (iv)   The patent applications referred to in the Relevant Patent Matters
were prepared and submitted in accordance with all applicable legal and
procedural requirements, all annuity, maintenance and other necessary fees have
been timely paid and we are not aware of any facts which could form a basis for
a successful challenge to the validity or enforceability of any patent issued
from such patent applications.  The patents referred to in the Relevant Patent
Matters were obtained in accordance with all applicable legal and procedural
requirements, all annuity, maintenance and other necessary fees have been timely
paid and we are not aware of any facts which could form a basis for a successful
challenge to the validity or enforceability of such patents;

     (v)    Except as set forth in Schedule C to this letter, the discoveries,
inventions, products, processes, technology and know-how which are a part of the
Relevant Patent Matters and Relevant License Agreements do not, to our knowledge
after due inquiry, infringe or conflict with any right which is the subject of a
patent known to McKinley or McKinley Optics, which infringement or conflict
could result in any material adverse effect upon the Company's ability to
utilize and enjoy the benefits and rights provided to the Company under the
Relevant License Agreements; and

     (vi)    We have reviewed the statements contained in the Prospectus under
the sub-heading "Business--Patents and Proprietary Rights" and insofar as such
statements relate to the Relevant Patent Matters or the Relevant License
Agreements, such statements are correct and complete.

     The undersigned understands that you, as representatives of the several
underwriters (the "Representatives"), propose to enter into an Underwriting
Agreement with Vista Medical Technologies, Inc. (the "Company") providing for
the public offering (the "Public Offering") by the several underwriters,
including yourselves, of the common stock (the "Common Stock"), $.01 par value
per share, of the Company.  The undersigned recognizes that the Public Offering
will benefit the Company by, among other things, raising additional capital for
product introduction, marketing and general corporate purposes.

     In consideration of the underwriters' agreement to purchase shares of
Common Stock and conduct the Public Offering, and for other good and valuable
consideration, the receipt and adequacy of which is hereby acknowledged, the
undersigned irrevocably agrees that, without the prior written consent of the
Representatives, the undersigned will not, directly or indirectly, offer, sell,
contract to sell, grant any option to purchase, make any short sale, or
otherwise dispose of any Common Stock of the Company, or other securities of the
Company that are substantially similar to Common Stock (including, without
limitation, any securities that are convertible into or exchangeable for, or
that represent the right to receive upon exercise or otherwise, Common Stock or
any substantially similar securities), or any Common Stock of the Company which
may be deemed to be beneficially owned by the undersigned in accordance with the
rules and regulations of the Securities and Exchange Commission, for a period of
180 days from and after the date of the final Prospectus covering the public
offering of shares of the Common Stock.  The undersigned acknowledges that you
and the Company are relying on the agreements of the undersigned contained
herein in carrying out the Public Offering and in entering into underwriting
arrangements with respect thereto.

     The foregoing restriction is expressly agreed to preclude the undersigned
from engaging in any hedging or other transaction which is designed to or
reasonably expected to lead to or result in a sale or disposition of the shares

someone other than the undersigned.  Such prohibited hedging or other
transactions would include without limitation any short sale or any purchase,
sale or grant of any right (including without limitation any put or call option)
with respect to any of the shares of Common Stock or with respect to any
security that includes, relates to, or derives any significant part of its value
from such shares.

event, the assets and funds thus distributed among the holders of the Preferred
Stock shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Preferred Stock in proportion to the preferential
amount each such holder would have been entitled to receive pursuant to this
Section 3 if such distribution had been sufficient to permit the full payment of
such preferential amount.

               b.   After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Section
3.a. above, the holders of the Common and Preferred Stock shall be entitled to
receive the remaining assets of the Corporation in proportion to the shares of
Common Stock then held by them and the shares of Common Stock which they have
the right to acquire upon conversion of Preferred Stock until such time as the
distributions made to the holders of the Preferred Stock (taken together with
all payments made pursuant to Section 3.a. above) equal, with respect to the
Series A Preferred, $3.975 per share for each share of Series A Preferred then
held by them, with respect to the Series B Preferred, $12.00 per share for each
share of Series B Preferred then held by them and, with respect to the Series C
Preferred, $15.00 per share for each share of Series C Preferred then held by
them.  If, upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Preferred Stock shall be insufficient to
permit the payment to such holders of the full aforesaid preferential amounts,
then the entire remaining assets and funds of the Corporation legally available
for distribution after payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Section
3.a. above shall be distributed ratably among the holders of the Common and
Preferred Stock in proportion to the preferential amount each such holder would
have been entitled to receive pursuant to this Section 3 if such distribution
had been sufficient to permit the full payment of the preferential amounts under
this Section 3.b. to the holders of the Preferred Stock.

               c.   After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Sections
3.a. and 3.b. above, the holders of the Common shall be entitled to receive all
remaining assets of the Corporation in proportion to the shares of Common Stock
then held by them.

               d.   For purposes of this Section 3, a liquidation, dissolution
or winding up of the Corporation shall be deemed to be occasioned by, or to
include, the Corporation's sale of all or substantially all of its assets or the
acquisition of this Corporation by another entity by means of merger or
consolidation resulting in the exchange of the outstanding shares of this
Corporation for securities or consideration issued, or caused


                                       3.
<PAGE>

to be issued, by the acquiring Corporation or its subsidiary in which the
stockholders of the Corporation are holders of less than 50% of voting power of
the surviving corporation.

          4.   CONVERSION.  The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

               a.   OPTIONAL AND AUTOMATIC CONVERSION.  Each share of Preferred
Stock shall be convertible at the option of the holder thereof, without payment
of additional consideration, at any time after the date of issuance of such
share, at the office of the Corporation or any transfer agent for the Preferred
Stock, into such number of fully paid and nonassessable shares of Common as is
determined by dividing, with respect to the Series A Preferred, $1.325, with
respect to the Series B Preferred, $4.00, or, with respect to the Series C
Preferred, $5.00 by the Conversion Price, determined as hereinafter provided, in
effect at the time of conversion.  The price at which shares of Common shall be
deliverable upon conversion of the Series A-1 Preferred (the "Series A-1
Conversion Price") shall initially be $1.325 per share of Common.  The price at
which shares of Common shall be deliverable upon conversion of the Series A-3
Preferred (the "Series A-3 Conversion Price") shall initially be $1.325 per
share of Common.  The price at which shares of Common shall be deliverable upon
conversion of the Series B Preferred (the "Series B Conversion Price") shall
initially be $4.00 per share of Common.  The price at which shares of Common
shall be deliverable upon conversion of the Series C Preferred (the "Series C
Conversion Price") shall initially be $5.00 per share of Common.  As used in
this Section 4., the term "Conversion Price" shall refer to the Series A-1
Conversion Price, the Series A-3 Conversion Price, the Series B Conversion Price
or the Series C Conversion Price, as the case may be.  The initial Series A-1
Conversion Price, Series A-3 Conversion Price, Series B Conversion Price and
Series C Conversion Price shall be subject to adjustment as hereinafter
provided.

     Each share of Preferred Stock shall automatically be converted into shares
of Common at the then effective Conversion Price in the event of either (i) the
closing of a firm commitment underwritten public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended
(the "Act"), covering the offer and sale of Common (whether for the account of
the Corporation or for the account of one or more stockholders of the
Corporation) of the Corporation to the public in which the aggregate gross cash
proceeds to the Corporation (prior to underwriters' discounts and expenses) are
equal to or exceed $15,000,000 and the public offering price is equal to or
exceeds $5.00 per share of Common (as adjusted for any stock dividends,
combinations or splits with respect to such shares) (a "Qualified Public
Offering") or (ii) the written consent of holders of more than fifty percent
(50%) of the then outstanding shares of Preferred Stock voting together as a
single class (a "Qualifying Consent").  In the event of the automatic conversion
of the Preferred Stock upon a Qualified Public Offering, the conversion of
Preferred Stock shall be deemed to have occurred immediately prior to the
closing of such Qualified Public Offering.  In the event of the automatic
conversion of the shares of Preferred Stock upon a Qualifying Consent, the
conversion of Preferred Stock shall be deemed to have occurred on the date
specified in such Qualifying Consent.


                                       4.
<PAGE>


               b.   MECHANICS OF CONVERSION.  No fractional shares of Common
shall be issued upon conversion of Preferred Stock.  In lieu of any fractional
shares to which the holder would otherwise be entitled, the Corporation shall
pay cash equal to such fraction multiplied by the then effective Conversion
Price.  Before any holder of Preferred Stock shall be entitled to convert the
same into full shares of Common, it shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent for the Preferred Stock, and shall give written notice to the
Corporation at such office that it elects to convert the same (except that no
such written notice of election to convert shall be necessary in the event of an
automatic conversion pursuant to Section 4.a.).  The Corporation shall, as soon
as practicable thereafter, issue and deliver at such office to such holder of
Preferred Stock a certificate or certificates, registered in such names as
specified by the holder, for the number of shares of Common to which he shall be
entitled as aforesaid and a check payable to the holder in the amount of any
cash amounts payable as the result of a conversion into fractional shares of
Common, and any declared and unpaid dividends on the converted Preferred Stock.
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 Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Common on such date (except that in the
event of an automatic conversion (i) upon a Qualified Public Offering pursuant
to Section 4.a. such conversion shall be deemed to have been made immediately
prior to the closing of the Qualified Public Offering and (ii) upon a Qualifying
Consent pursuant to Section 4.a. such conversion shall be deemed to have been
made on the date specified in such Qualifying Consent).  If the conversion is in
connection with an underwritten offering of securities registered pursuant to
the Act, the conversion may, at the option of any holder tendering Preferred
Stock for conversion, be conditioned upon the closing with the underwriter of
the sale of securities pursuant to such offering, in which event the person(s)
entitled to receive the Common issuable upon such conversion of the Preferred
Stock shall not be deemed to have converted such Preferred Stock until
immediately prior to the closing of such sale of securities.

               c.   ADJUSTMENTS TO SERIES A-1 CONVERSION PRICE, SERIES A-3
CONVERSION PRICE, SERIES B CONVERSION PRICE AND SERIES C CONVERSION PRICE FOR
DILUTIVE ISSUES.

                    (1)  SPECIAL DEFINITIONS.  For purposes of this Section 4.c.
and Section 5, the following definitions shall apply:

                         (a)  "OPTION" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common or Convertible
Securities.

                         (b)  "ORIGINAL ISSUE DATE" shall mean, with respect to
the Series A-1 Preferred, the date on which a share of Series A-1 Preferred was
first issued, and with respect to the Series A-3 Preferred, the date on which a
share of Series A-3 Preferred was first issued, with respect to the Series B
Preferred, the date on which a share


                                       5.
<PAGE>


of Series B Preferred was first issued and with respect to the Series C
Preferred, the date on which a share of Series C Preferred was first issued.

                         (c)  "CONVERTIBLE SECURITIES" shall mean any evidences
of indebtedness, shares (other than Common and Preferred Stock) or other
securities directly or indirectly convertible into or exchangeable for Common.

                         (d)  "ADDITIONAL SHARES OF COMMON" shall mean all
shares of Common issued (or, pursuant to Section 4.c.(3), deemed to be issued)
by the Corporation after the Original Issue Date, other than shares of Common
issued or issuable:

                              i)   upon conversion of shares of Preferred Stock
authorized herein;

                              ii)  to officers, directors or employees of, or
consultants to, the Corporation pursuant to any plan or agreement approved by
the Board of Directors;

                              iii) as a dividend or distribution on the
Preferred Stock or any event for which adjustment is made pursuant to Sections
4.d. or 4.e. hereof;

                              iv)  in connection with equipment leasing or bank
financing transactions, provided such shares are issued for other than primarily
equity financing purposes;

                              v)   pursuant to transactions involving technology
licensing, research or development activities or the distribution or manufacture
of the Corporation's products, provided that each of the forgoing transactions
is for other than primarily equity financing purposes; or

                              vi)  by way of dividend or other distribution on
shares excluded from the definition of Additional Shares of Common by the
foregoing clauses i) through v) or this clause vi) or on shares of Common so
excluded.

                    (2)  NO ADJUSTMENT OF SERIES A-1 CONVERSION PRICE,
SERIES A-3 CONVERSION PRICE, SERIES B CONVERSION PRICE OR SERIES C CONVERSION
PRICE.  No adjustment in the Series A-1 Conversion Price, Series A-3 Conversion
Price, Series B Conversion Price or Series C Conversion Price shall be made in
respect of the issuance of Additional Shares of Common unless the consideration
per share for an Additional Share of Common issued or deemed to be issued by the
Corporation is less than the Series A-1 Conversion Price, Series A-3 Conversion
Price, Series B Conversion Price or Series C Conversion Price, respectively, in
effect on the date of, and immediately prior to, the issue of such Additional
Shares.


                                       6.
<PAGE>


                    (3)  ISSUE OF SECURITIES DEEMED ISSUE OF ADDITIONAL SHARES
OF COMMON -- OPTIONS AND CONVERTIBLE SECURITIES.  In the event the Corporation
at any time or from time to time after the Original Issue Date shall issue any
Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common issuable
upon the exercise of such Options or, in the case of Convertible Securities and
Options therefor, the conversion or exchange of such Convertible Securities,
shall be deemed to be Additional Shares of Common issued as of the time of such
issue or, in case such a record date shall have been fixed, as of the close of
business on such record date, provided that in any such case in which Additional
Shares of Common are deemed to be issued:

                         (a)  no further adjustment in the Series A-1 Conversion
Price, Series A-3 Conversion Price, Series B Conversion Price or Series C
Conversion Price shall be made upon the subsequent issue of Convertible
Securities or shares of Common upon the exercise of such Options or conversion
or exchange of such Convertible Securities;

                         (b)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, or decreases in the number of shares
of Common issuable, upon the exercise, conversion or exchange thereof, the
Series A-1 Conversion Price, Series A-3 Conversion Price, Series B Conversion
Price and Series C Conversion Price computed upon the original issue thereof (or
upon the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                         (c)  no readjustment pursuant to clause (b) above shall
have the effect of increasing the Series A-1 Conversion Price, Series A-3
Conversion Price, Series B Conversion Price or Series C Conversion Price to an
amount which exceeds the lower of (i) such Series A-1 Conversion Price,
Series A-3 Conversion Price, Series B Conversion Price or Series C Conversion
Price, respectively, on the original adjustment date with respect to such deemed
issuance of Additional Shares of Common, or (ii) such Series A-1 Conversion
Price, Series A-3 Conversion Price, Series B Conversion Price or Series C
Conversion Price, respectively, that would have resulted from any issuance of
Additional Shares of Common between such original adjustment date and such
readjustment date; and

                         (d)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any decrease in the
consideration payable to the Corporation upon the exercise, conversion or
exchange thereof, the Series A-1 Conversion Price, Series A-3 Conversion Price,
Series B Conversion Price and Series C Conversion Price computed upon the
original issue thereof (or upon the occurrence of a record date with respect
thereto), and any subsequent adjustments based thereon, shall, upon any such
decrease becoming effective, be recomputed to reflect such decrease insofar


                                       7.
<PAGE>


as it affects such Options or the rights of conversion or exchange under such
Convertible Securities.

                    (4)  ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF
ADDITIONAL SHARES OF COMMON.  In the event this Corporation shall issue
Additional Shares of Common (including Additional Shares of Common deemed to be
issued pursuant to Section 4.c.(3)) without consideration or for a consideration
per share less than the Series A-1 Conversion Price, Series A-3 Conversion
Price, Series B Conversion Price or Series C Conversion Price in effect on the
date of and immediately prior to such issue, then and in such event, such Series
A-1 Conversion Price, Series A-3 Conversion Price, Series B Conversion Price or
Series C Conversion Price, respectively, shall be reduced, concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying such Series A-1 Conversion Price, Series A-3 Conversion Price,
Series B Conversion Price or Series C Conversion Price, respectively, by a
fraction, the numerator of which shall be the number of shares of Common
outstanding immediately prior to such issue plus the number of shares of Common
which the aggregate consideration received by the Corporation for the total
number of Additional Shares of Common so issued would purchase at such Series A-
1 Conversion Price, Series A-3 Conversion Price, Series B Conversion Price or
Series C Conversion Price, respectively, in effect immediately prior to such
issue; and the denominator of which shall be the number of shares of Common
outstanding immediately prior to such issue plus the number of such Additional
Shares of Common so issued; and provided further that, for the purposes of this
Section 4.c.(4): (i) no shares of Common issued or issuable upon conversion of
Preferred Stock shall be deemed to be outstanding and all such shares shall be
excluded from such calculation, (ii) all shares of Common issuable upon
conversion of outstanding Options and Convertible Securities (excluding
outstanding Preferred Stock) shall be deemed to be outstanding and all such
shares shall be included in such calculation, and (iii) except as provided in
the foregoing clauses (i) and (ii) above, immediately after any Additional
Shares of Common are deemed issued pursuant to Section 4.c.(3), such Additional
Shares of Common shall be deemed to be outstanding.  The Series A-1 Conversion
Price, Series A-3 Conversion Price, Series B Conversion Price and Series C
Conversion Price shall not be increased except as set forth in Section
4.c.(3)(b) and in Section 4.d.

                    (5)  DETERMINATION OF CONSIDERATION.  For purposes of this
Section 4.c., the consideration received by the Corporation for the issue of any
Additional Shares of Common shall be computed as follows:

                         (a)  CASH AND PROPERTY.  Such consideration shall:

                              i)   insofar as it consists of cash, be computed
at the aggregate amount of cash received by the Corporation excluding amounts
paid or payable for accrued interest or accrued dividends;

                              ii)  insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and


                                       8.
<PAGE>


                              iii) in the event Additional Shares of Common are
issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses i) and ii) above, as
reasonably determined in good faith by the Board of Directors.

                         (b)  OPTIONS AND CONVERTIBLE SECURITIES.  The
consideration per share received by the Corporation for Additional Shares of
Common deemed to have been issued pursuant to Section 4.c.(3), relating to
Options and Convertible Securities, shall be determined by dividing:

                              i)   the total amount, if any, received or
receivable by the Corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Corporation upon the exercise of such Options or
the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such Options for Convertible
Securities and the conversion or exchange of such Convertible Securities, by

                              ii)  the maximum number of shares of Common (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

               d.   ADJUSTMENT FOR STOCK SPLITS, DIVIDENDS AND COMBINATIONS.  If
the Corporation shall at any time or from time to time effect a subdivision of
the outstanding Common, or shall issue a dividend of Common on its outstanding
Common, the Series A-1 Conversion Price, Series A-3 Conversion Price, Series B
Conversion Price and Series C Conversion Price then in effect immediately before
that subdivision or dividend shall be proportionately decreased, and conversely,
if the Corporation shall combine the outstanding shares of Common, the Series A-
1 Conversion Price, Series A-3 Conversion Price, Series B Conversion Price and
Series C Conversion Price then in effect immediately before the combination
shall be proportionately increased.  Any adjustment under this Section 4.d.
shall become effective at the close of business on the date the subdivision or
combination becomes effective or on the date on which the dividend is declared.

               e.   ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the
event the Corporation at any time or from time to time shall make or issue, or
fix a record date for the determination of holders of Common entitled to receive
a dividend or other distribution payable in securities of the Corporation other
than shares of Common, then, and in each such event, provision shall be made so
that the holders of Series A-1 Preferred, Series A-3 Preferred, Series B
Preferred and Series C Preferred shall receive upon conversion thereof, in
addition to the number of shares of Common receivable thereupon, the amount of
securities of the Corporation that they would have received had their Series A-1
Preferred, Series A-3 Preferred, Series B Preferred and Series C Preferred been


                                       9.
<PAGE>


converted into Common on the date of such event, giving effect to all
adjustments called for with respect to such securities during the period from
the date of such event to and including the conversion date.

               f.   ADJUSTMENT FOR MERGER OR REORGANIZATION.  In case of any
consolidation or merger of the Corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the Corporation to
another corporation (other than a consolidation, merger or conveyance provided
for elsewhere in this Section 4 or Section 3), provisions shall be made so that
holders of shares of Series A-1 Preferred, Series A-3 Preferred, Series B
Preferred and Series C Preferred shall thereafter be convertible into the number
of shares of stock or other securities or property to which a holder of the
number of shares of Common of the Corporation deliverable upon conversion of
such Series A-1 Preferred, Series A-3 Preferred, Series B Preferred and Series C
Preferred would have been entitled upon such consolidation, merger or
conveyance; and, in any case, appropriate adjustment (as reasonably determined
in good faith by the Board of Directors) shall be made in the application of the
provisions herein set forth with respect to the rights and interest thereafter
of the holders of the Series A-1 Preferred, Series A-3 Preferred, Series B
Preferred and Series C Preferred, to the end that the provisions set forth
herein (including provisions with respect to changes in and other adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as reasonably
may be, in relation to any shares of stock or other property thereafter
deliverable upon the conversion of the Series A-1 Preferred, Series A-3
Preferred, Series B Preferred and Series C Preferred.

               g.   ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.
If the Common issuable upon the conversion of the Series A-1 Preferred,
Series A-3 Preferred, Series B Preferred and Series C Preferred shall be changed
into the same or different number of shares of any class or series of stock,
whether by capital reorganization, reclassification or otherwise (other than as
set forth above in this Section 4), then and in each such event the holder of
each share of Series A-1 Preferred, Series A-3 Preferred, Series B Preferred and
Series C Preferred shall have the right thereafter to convert such share into
the kind and amount of shares of stock and other securities and property
receivable upon such reorganization, reclassification or other change by holders
of the number of shares of Common into which such shares of Series A-1
Preferred, Series A-3 Preferred, Series B Preferred and Series C Preferred might
have been converted immediately prior to such reorganization, reclassification
or change, all subject to further adjustment as provided herein.

               h.   NO IMPAIRMENT.  The Corporation will not, by amendment of
this Amended and Restated Certificate 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 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-1 Preferred, Preferred, Series
A-3 Preferred, Series B Preferred and Series C Preferred against impairment.


                                       10.
<PAGE>


               i.   CERTIFICATE AS TO ADJUSTMENTS.  Upon the occurrence of each
adjustment or readjustment of the Series A-1 Conversion Price, Series A-3
Conversion Price, Series B Conversion Price or Series C Conversion Price
pursuant to this Section 4, the Corporation at its expense shall promptly
compute such adjustments or readjustments in accordance with the terms hereof
and furnish to each holder of any such Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based.  The Corporation shall, upon the
written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Series A-1 Conversion Price, Series A-3
Conversion Price, Series B Conversion Price or Series C Conversion Price at the
time in effect, and (iii) the number of shares of Common and the amount, if any,
of other property which at the time would be received upon the conversion of
such holder's shares.

               j.   NOTICES OF RECORD DATE.  In the event of any taking by the
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 which is the same as cash dividends paid in
previous quarters) or other distribution, the Corporation shall mail to each
holder of Preferred Stock at least ten (10) 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 or distribution.  Each such written notice
shall be given by first class mail, postage prepaid, addressed to the holders of
Preferred Stock at the address for each such holder as shown on the books of
this Corporation.

               k.   COMMON STOCK RESERVED.  The Corporation shall at all times
reserve and keep available out of its authorized but unissued shares of Common,
solely for the purpose of effecting the conversion of the shares of Preferred
Stock, such number of shares of Common as shall from time to time be sufficient
to effect the conversion of all outstanding shares of Preferred Stock, and if at
any time the number of authorized but unissued shares of Common shall not be
sufficient to effect the conversion of all then outstanding shares of Preferred
Stock, the Corporation shall take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of
Common to such number of shares as shall be sufficient for such purpose.

          5.   VOTING RIGHTS.  Each holder of shares of Series A-1 Preferred
shall be entitled to the number of votes equal to the number of shares of Common
into which such shares of Series A-1 Preferred could be converted on the record
date for the vote or the date of the solicitation of any written consent of
stockholders and shall have voting rights and powers equal to the voting rights
and powers of the Common.  The Series A-3 Preferred shall be non-voting
Preferred, except as otherwise required by law.  Each holder of shares of Series
B Preferred shall be entitled to the number of votes equal to the number of
shares of Common into which such shares of Series B Preferred could be converted
on the record date for the vote or the date of the solicitation of any written
consent of stockholders and shall have voting rights and powers equal to the
voting rights and powers of the Common.  Each holder of shares of Series C
Preferred shall be entitled to the number of votes equal to the number of shares
of Common into which such shares of Series C Preferred could be


                                       11.
<PAGE>


converted on the record date for the vote or the date of the solicitation of any
written consent of stockholders and shall have voting rights and powers equal to
the voting rights and powers of the Common.  Each holder of Common shall be
entitled to one vote per share of Common held by such holder.  The holder of
each share of Series A-1 Preferred, Series B Preferred and Series C Preferred
shall be entitled to notice of any stockholders' meeting in accordance with the
Bylaws of the Corporation and shall vote with holders of the Common upon all
matters submitted to a vote of stockholders, except those matters required by

employment, and (ii) as approved by the Board of Directors);

                    (5)  merge into or consolidate with any other corporation or

          7.   STATUS OF CONVERTED STOCK.  In the event any shares of Preferred
Stock shall be converted pursuant to Section 4 hereof, the shares so converted
shall be cancelled and shall not be issuable by the Corporation.  The
Certificate of Incorporation of this Corporation shall be appropriately amended
to effect the corresponding reduction in the Corporation's authorized capital
stock.

          8.   RESIDUAL RIGHTS.  All rights accruing to the outstanding shares
of the Corporation not otherwise expressly provided for in this Amended and
Restated Certificate of Incorporation shall be vested in the Common.

          9.   REPURCHASE OF SHARES.  In connection with repurchases by this
Corporation of its Common Stock pursuant to agreements with certain of the
holders thereof approved by this Corporation's Board of Directors, each holder
of Preferred Stock shall be deemed to have waived the application, in whole or
in part, of any provisions of the Delaware General Corporation Law or any
applicable law of any other state which might limit or prevent or prohibit such
repurchases.

                                   ARTICLE V.

fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law or (iv) for any transaction from which the director derived any
improper personal benefit.  If the Delaware General Corporation Law is hereafter
amended to further reduce or to authorize, with the approval of the
Corporation's stockholders, further reductions in the liability of the
Corporation's directors for breach of fiduciary duty, then a director of the
Corporation shall not be liable for any such breach to the fullest extent
permitted by the Delaware General Corporation Law as so amended.

          3.   CONSISTENCY.  In the event of any inconsistency between Sections
1 and 2 of this subsection A, the controlling Section, as to any particular

the director in question the greatest protection from liability.

Code) through bylaw provisions, agreements with agents, vote of stockholders or
disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 317 of the California Corporations
Code, subject only to applicable limits set forth in Section 204 of the
California Corporations Code, with respect to actions for breach of duty to the
Corporation and its stockholders.

          2.   DELAWARE.  To the extent permitted by applicable law, this
Corporation is also authorized to provide indemnification of (and advancement of
expenses to) such agents (and any other persons to which Delaware law permits

agreements with such agents or other persons, vote of stockholders or
disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the Delaware General
Corporation Law, subject only to limits created by applicable Delaware law
(statutory or non-statutory), with respect to actions for breach of duty to the
Corporation, its stockholders, and others.

          3.   CONSISTENCY.  In the event of any inconsistency between Sections
1 and 2 of this subsection B, the controlling Section, as to any particular
issue with regard to any particular matter, shall be the one which authorizes
for the benefit of the agent or other person in question the provision of the
fullest, promptest, most certain or otherwise most favorable indemnification
and/or advancement.

     C.   EFFECT OF REPEAL OR MODIFICATION.  Any repeal or modification of any

of Directors is expressly authorized to make, repeal, alter, amend and rescind

                         CERTIFICATE OF AMENDMENT OF THE
              AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF
                        VISTA MEDICAL TECHNOLOGIES, INC.



     Vista Medical Technologies, Inc., a corporation organized and existing
under and by virtue of the General Corporation Law of the State of Delaware (the
"Corporation"),

     DOES HEREBY CERTIFY:

     FIRST:  That resolutions were duly adopted by the Board of Directors of the
Corporation setting forth proposed amendments to the Amended and Restated
Certificate of Incorporation of the Corporation, and declaring said amendments
to be advisable and recommended for approval by the stockholders of the
Corporation.  The resolutions setting forth the proposed amendments are as
follows:

     NOW, THEREFORE, BE IT RESOLVED, that the FIRST paragraph of Section A of
     Article IV of the Amended and Restated Certificate of Incorporation of the
     Corporation be amended in its entirety to read as follows:

          "A.  CLASSES OF STOCK.  This Corporation is authorized to issue two
     (2) classes of shares, to be designated "Common" and "Preferred" and
     referred to herein as the "Common Stock" or the "Preferred Stock"
     respectively.  The total number of shares of Common Stock the Corporation
     is authorized to issue is twenty-five million (25,000,000). The par value
     is $0.01 per share.  The total number of shares of Preferred Stock the
     Corporation is authorized to issue is eighteen million (18,000,000).  The
     par value is $0.01 per share.

          Upon the amendment of this Article IV as set forth herein, each four
     shares of Common Stock, par value $0.01, issued and outstanding at such
     time shall be combined, reclassified and converted into three shares of
     Common Stock, par value $0.01 (the "new shares").  No fractional share
     shall be issued upon the combination, reclassification and conversion of
     any share or shares of Common Stock.  All shares of Common Stock (including
     fractions thereof) issuable upon the combination, reclassification and
     conversion of one or more shares of Common Stock by a holder thereof
     (including, for this purpose, a holder of shares of Common Stock issuable
     upon conversion of Preferred Stock) shall be aggregated for purposes of
     determining whether the combination, reclassification and conversion would
     result in the issuance of any fractional share.  If, after the
     aforementioned aggregation, the combination, reclassification and
     conversion would result in the issuance of a fraction of a share of Common
     Stock, the Corporation shall, in lieu of issuing any fractional share, pay


<PAGE>


     the holder otherwise entitled to such fraction a sum in cash equal to the
     fraction multiplied by the fair market value per share of the Common Stock
     (as determined in a reasonable manner by the Board of Directors or a
     committee thereof) as of the date of filing of this Certificate of
     Amendment.  An amount shall be transferred from capital to surplus so that
     the amount of capital represented by the new shares in the aggregate at the
     time of filing of this Certificate of Amendment shall equal the aggregate
     number of new shares multiplied by $0.01.  Unless otherwise requested by
     the holders thereof, the share certificates representing the shares
     outstanding prior to the filing of this Certificate of Amendment shall
     represent such number of new shares as combined, reclassified and converted
     following the filing of this Certificate of Amendment.  Upon surrender by a
     holder of Common Stock of a certificate or certificates for Common Stock,
     $0.01 par value, duly endorsed, at the office of this Corporation, this
     Corporation shall, as soon as practicable thereafter, issue and deliver at
     such office to such holder of Common Stock, or to the nominee or nominees
     of such holder, a certificate or certificates for the number of new shares
     to which such holder shall be entitled as aforesaid."

     SECOND:  That, thereafter, the stockholders approved the foregoing
amendment by written consent in accordance with Section 228 of the Delaware
General Corporation Law.

     THIRD:  That said amendment was duly adopted in accordance with the
provisions of Section 242 of the Delaware General Corporation Law.  The total
number of outstanding shares of the Corporation is 720,633 shares of Common
Stock, 8,094,340 shares of Series A-1 Preferred Stock, 154,581 shares of Series
A-3 Preferred Stock, 1,325,331 shares of Series B Preferred Stock and 2,000,000
shares of Series C Preferred Stock.  The number of shares voting in favor of the
amendment equaled or exceeded the vote required, such required vote being (a) a
majority of the outstanding shares of Common Stock, Series A-1 Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock (voting together on an as-
converted basis), (b) a majority of the outstanding shares of Series A-1
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock (voting
together as a class) and (c) 66 2/3% of the outstanding shares of Series A-1
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock (voting
together as a class).  The holders of Series A-3 are not entitled to vote,
except as required by law.


                                       2.

     FOURTH:  That the capital of said Corporation shall not be reduced under or
by reason of said amendment.

                      OF VISTA MEDICAL TECHNOLOGIES, INC.,
                             a Delaware corporation



     Vista Medical Technologies, Inc., a corporation organized and existing
under the laws of the State of Delaware, hereby certifies as follows:

     1.   The name of the corporation is Vista Medical Technologies, Inc.  The

     2.   Pursuant to Sections 242 and 245 of the General Corporation Law of the
State of Delaware, this Second Restated Certificate of Incorporation was adopted

     3.   The text of the Certificate of Incorporation as heretofore amended or

     (B)  ISSUANCE OF PREFERRED STOCK.  The Preferred Stock may be issued from

authorized, by filing one or more certificates pursuant to the Delaware General
Corporation Law (each, a "Preferred Stock Designation"), to fix or alter from
time to time the designations, powers, preferences and rights of each such
series of Preferred Stock and the qualifications, limitations or restrictions
thereof, including without limitation the dividend rights, dividend rate,
conversion rights, voting rights, rights and terms of redemption (including
sinking fund provisions), redemption price or prices, and the liquidation
preferences of any wholly-unissued series of Preferred Stock, and to establish
from time to time the number of shares constituting any such series and the
designation thereof, or any of them; and to increase or decrease the number of
shares of any series subsequent to the issuance of shares of 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 decreased in accordance with the
foregoing sentence, the shares constituting such decrease shall resume the
status that they had prior to the adoption of the resolution originally fixing
the number of shares of such series.

     (C)  RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF COMMON STOCK.

          1. DIVIDEND RIGHTS.  Subject to the prior or equal rights of holders

legally available therefor, such dividends as may be declared from time to time
by the Board of Directors.

          2. REDEMPTION.  The Common Stock is not redeemable upon demand of any
holder thereof or upon demand of this corporation.

director derived any improper personal benefit.  If the Delaware General
Corporation Law is hereafter amended to further reduce or to authorize, with the

permitted by the Delaware General Corporation Law as so amended.

this corporation to provide indemnification) through bylaw provisions,
agreements with such agents or other persons, vote of stockholders or
disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the Delaware General
Corporation Law, subject only to limits created by applicable Delaware law
(statutory or non-statutory), with respect to actions for breach of duty to the
corporation, its stockholders and others.

     (C)  EFFECT OF REPEAL OR MODIFICATION.  Any repeal or modification of any
of the foregoing provisions of this Article V shall be prospective and shall not
adversely affect any right or protection of a director, officer, agent or other
person existing at the time of, or increase the liability of any director of the
corporation with respect to any acts or omissions of such director occurring
prior to, such repeal or modification.

term of office of the first class to expire at the second Annual Meeting of
Stockholders, the term of office of the second class to expire at the third
Annual Meeting of Stockholders and the term of office of the third class to
expire at the fourth Annual Meeting of Stockholders.  At each Annual Meeting of
Stockholders following such initial classification and election, Directors
elected to succeed those Directors whose terms expire shall be elected for a
term of office to expire at the third succeeding Annual Meeting of Stockholders
after their election.  Additional directorships resulting from an increase in
the number of Directors shall be apportioned among the classes as equally as
possible as determined by the Board of Directors.

                                   ARTICLE VII

     No holder of shares of stock of the corporation shall have any preemptive
or other right, except as such rights are expressly provided by contract, to
purchase or subscribe for or receive any shares of any class, or series thereof,
of stock of the corporation, whether now or hereafter authorized, or any
warrants, options, bonds,


                                       -3-

<PAGE>

debentures or other securities convertible into, exchangeable for or carrying
any right to purchase any share of any class, or series thereof, of stock; but

purchase any shares of any class, or series thereof, of stock may be issued or
disposed of by the Board of Directors to such persons, and on such terms and for
such lawful consideration as in its discretion it shall deem advisable or as the
corporation shall have by contract agreed.

vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented.  At such adjourned

                                      III.

                                    DIRECTORS

     Section 1.       The authorized number of directors of this Corporation
shall be not less than five (5) nor more than nine (9), the exact number of
directors to be fixed


                                       -4-
<PAGE>

from time to time within such limit by a duly adopted resolution of the Board of
Directors or stockholders.  The exact number of directors presently authorized
shall be seven (7) until changed within the limits specified above by a duly
adopted resolution of the Board of Directors or stockholders.

     Directors shall hold office until the next annual meeting of stockholders
and until their respective successors are elected.  If any such annual meeting
is not held, or the directors are not elected thereat, the directors may be
elected at any special meeting of stockholders held for that purpose.  Directors
need not be stockholders.

     Section 2.       Vacancies and newly created directorships resulting from
any increase in the authorized number of directors may be filled by a majority
of the directors then in office, though less than a quorum, or by a sole
remaining director, and the directors so chosen shall hold office until the next
annual election and until their successors are duly elected and shall qualify,
unless sooner displaced.  If there are no directors in office, then an election
of directors may be held in the manner provided by statute.  If, at the time of
filling any vacancy or any newly created directorship, the directors then in
office shall constitute less than a majority of the whole board (as constituted
immediately prior to any such increase), the Court of Chancery may, upon
application of any stockholder or stockholders holding at least ten percent of
the total number of the shares at the time outstanding having the right to vote
for such directors, summarily order an election to be held to fill any such
vacancies or newly created directorships, or to replace the directors chosen by
the directors then in office.

     Section 3.       The business of the corporation shall be managed by or
under the direction of its board of directors which may exercise all such powers
of the corporation


                                       -5-
<PAGE>

and do all such lawful acts and things as are not by statute or by the
certificate of incorporation or by these bylaws directed or required to be
exercised or done by the stockholders.

                       MEETINGS OF THE BOARD OF DIRECTORS

     Section 4.       The Board of Directors of the corporation may hold
meetings, both regular and special, either within or without the State of
Delaware.

     Section 5.       The first meeting of each newly elected Board of Directors
shall be held at such time and place as shall be fixed by the vote of the
stockholders at the annual meeting and no notice of such meeting shall be
necessary to the newly elected directors in order legally to constitute the
meeting, provided a quorum shall be present.  In the event of the failure of the
stockholders to fix the time or place of such first meeting of the newly elected
Board of Directors, or in the event such meeting is not held at the time and
place so fixed by the stockholders, the meeting may be held at such time and
place as shall be specified in a notice given as hereinafter provided for
special meetings of the Board of Directors, or as shall be specified in a
written waiver signed by all of the directors.

     Section 6.       Regular meetings of the Board of Directors may be held
without notice at such time and at such place as shall from time to time be
determined by the board.

     Section 7.       Special meetings of the board may be called by the
President on four (4) days' notice to each director by mail or 48 hours' notice
to each director either personally or by telephone, facsimile or telegram;
special meetings shall be called by the President or Secretary in like manner
and on like notice on the written request of two


                                       -6-
<PAGE>

(2) directors unless the board consists of only one (1) director, in which case
special meetings shall be called by the President or Secretary in like manner
and on like notice on the written request of the sole director.

     Section 8.       At all meetings of the board a majority of the directors
shall constitute a quorum for the transaction of business and the act of a
majority of the directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by statute or by the certificate of incorporation.  If a
quorum shall not be present at any meeting of the Board of Directors, the
directors present thereat may adjourn the meeting from time to time, without
notice other than announcement at the meeting, until a quorum shall be present.

     Section 9.       Unless otherwise restricted by the certificate of
incorporation or these bylaws, any action required or permitted to be taken at
any meeting of the Board of Directors or of any committee thereof may be taken
without a meeting, if all members of the board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the board or committee.

     Section 10.      Unless otherwise restricted by the certificate of
incorporation or these bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in
the meeting can hear each other, and such participation in a meeting shall
constitute presence in person at the meeting.

     Section 11.      The Board of Directors may, by resolution passed by a
majority of the whole board, designate one or more committees, each committee to
consist of one or more of the directors of the corporation.  The board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee.

     In the absence or disqualification of a member of a committee, the member
or members thereof present at any meeting and not disqualified from voting,
whether or not such member or members constitute a quorum, may unanimously
appoint another member of the Board of Directors to act at the meeting in the
place of any such absent or disqualified member.


     Any such committee, to the extent provided in the resolution of the Board
of Directors, shall have and may exercise all the powers and authority of the
Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the certificate of incorporation, adopting an
agreement of merger or consolidation, recommending to the stockholders the sale,
lease or exchange of all or substantially all of the corporation's property and
assets, recommending to the stockholders a dissolution of the corporation or a
revocation of a dissolution, or amending the bylaws of the corporation; and,
unless the resolution or the certificate of incorporation expressly so provide,
no such committee shall have the power or authority to declare a dividend or to
authorize the issuance of stock.  Such committee or committees shall have such
name or


                                       -8-
<PAGE>

names as may be determined from time to time by resolution adopted by the Board
of Directors.

                            COMPENSATION OF DIRECTORS

     Section 13.      Unless otherwise restricted by the certificate of
incorporation or these bylaws, the Board of Directors shall have the authority
to fix the compensation of directors.  The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director.  No such payment shall preclude any director from serving
the corporation in any other capacity and receiving compensation therefor.
Members of special or standing committees may be allowed like compensation for
attending committee meetings.

                              REMOVAL OF DIRECTORS

     Section 14.      Unless otherwise restricted by the certificate of
incorporation or bylaw, any director or the entire Board of Directors may be
removed, with or without cause, by the holders of a majority of shares entitled

restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate which the corporation shall
issue to represent such class or series of stock, provided that, except as
otherwise provided in section 202 of the General Corporation Law of Delaware, in
lieu of the foregoing requirements, there may be set forth on the face or back
of the certificate which the corporation shall issue to represent such class or
series of stock, a statement that the corporation will furnish without charge to
each stockholder who so requests the powers, designations, preferences and
relative, participating, optional or other special rights of each class of stock
or series thereof and the qualifications, limitations or restrictions of such
preferences and/or rights.

     Section 2.       Any of or all the signatures on the certificate may be
facsimile.  In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased
to be such officer, transfer agent or registrar before such certificate is
issued, it may be issued by the corporation with the same effect as if he or she
were such officer, transfer agent or registrar at the date of issue.

                                LOST CERTIFICATES

     Section 3.       The Board of Directors may direct a new certificate or
certificates to be issued in place of any certificate or certificates
theretofore issued by the corporation alleged to have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
the certificate of stock to be lost, stolen or destroyed.  When authorizing such
issue of a new certificate or certificates, the Board of Directors may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or certificates, or his or
her legal representative, to advertise the same in such manner as it shall
require and/or to give the corporation a bond in such sum as it may direct as
indemnity against any claim that may be made against the corporation with
respect to the certificate alleged to have been lost, stolen or destroyed.

                                TRANSFER OF STOCK

     Section 4.       Upon surrender to the corporation or the transfer agent of
the corporation of a certificate for shares duly endorsed or accompanied by
proper evidence of succession, assignation or authority to transfer, it shall be
the duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.

                               FIXING RECORD DATE

     Section 5.       In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any


                                      -16-
<PAGE>

rights, or entitled to exercise any rights in respect of any change, conversion
or exchange of stock or for the purpose of any other lawful action, the Board of
Directors may fix, in advance, a record date, which shall not be more than sixty
(60) nor less than ten (10) days before the date of such meeting, nor more than
sixty (60) days prior to any other action.  A determination of stockholders of
record entitled to notice of or to vote at a meeting of stockholders shall apply
to any adjournment of the meeting; provided, however, that the Board of
Directors may fix a new record date for the adjourned meeting.

                             REGISTERED STOCKHOLDERS

     Section 6.       The corporation shall be entitled to recognize the
exclusive right of a person registered on its books as the owner of shares to
receive dividends, and to vote as such owner, and to hold liable for calls and
assessments a person registered on its books as the owner of shares and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                      VII.

                               GENERAL PROVISIONS

cash, in property, or in shares of the capital stock, subject to the provisions
of the certificate of incorporation.

     Section 2.       Before payment of any dividend, there may be set aside out
of any funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purposes as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

                                     CHECKS

                                 INDEMNIFICATION

     Section 6.       The corporation shall, to the fullest extent authorized
under the laws of the State of Delaware, as those laws may be amended and
supplemented from time to time, indemnify any director made, or threatened to be
made, a party to an action or proceeding, whether criminal, civil,
administrative or investigative, by reason of being a director of the
corporation or a predecessor corporation or, at the corporation's request, a
director or officer of another corporation, provided, however, that the
corporation shall indemnify any such agent in connection with a proceeding
initiated by such agent only if such proceeding was authorized by the Board of
Directors of the corporation.  The indemnification provided for in this Section
6 shall: (i) not be deemed exclusive of any other rights to which those
indemnified may be entitled under the corporation's certificate of
incorporation, any bylaw, agreement or vote of stockholders or disinterested
directors or otherwise, both as to action in their official capacities and as to
action in another capacity while holding such office, (ii) continue as to a
person who has ceased to be a director, and (iii) inure to the benefit of the
heirs, executors and administrators of such a person.  The corporation's
obligation to provide indemnification under this Section 6 shall be offset to
the extent of any other source of indemnification or any otherwise applicable
insurance coverage under a policy maintained by the corporation or any other
person.

          Expenses incurred by a director of the corporation in defending a
civil or criminal action, suit or proceeding by reason of the fact that such
director is or was a director of the corporation (or was serving at the
corporation's request as a director or officer of another corporation) shall be
paid by the corporation in advance of the final


                                      -19-
<PAGE>

disposition of such action, suit or proceeding upon receipt of an undertaking by
or on behalf of such director to repay such amount if it shall ultimately be
determined that such director is not entitled to be indemnified by the
corporation as authorized by relevant sections of the General Corporation Law of
Delaware.  Notwithstanding the foregoing, the corporation shall not be required
to advance such expenses to an agent who is a party to an action, suit or
proceeding brought by the corporation and approved by a majority of the Board of
Directors of the corporation which alleges willful misappropriation of corporate
assets by such agent, disclosure of confidential information in violation of
such agent's fiduciary or contractual obligations to the corporation or any
other willful and deliberate breach in bad faith of such agent's duty to the
corporation or its stockholders.

          The foregoing provisions of this Section 6 shall be deemed to be a
contract between the corporation and each director who serves in such capacity
at any time while this bylaw is in effect, and any repeal or modification
thereof shall not affect any rights or obligations then existing with respect to
any state of facts then or theretofore existing or any action, suit or
proceeding theretofore or thereafter brought based in whole or in part upon any
such state of facts.

          The Board of Directors in its discretion shall have power on behalf of
the corporation to indemnify any person, other than a director, made a party to
any action, suit or proceeding by reason of the fact that such person, such
person's testator or intestate, is or was an officer or employee of the
corporation.

          To assure indemnification under this Section 6 of all directors,
officers and employees who are determined by the corporation or otherwise to be
or to have been


                                      -20-
<PAGE>

"fiduciaries" of any employee benefit plan of the corporation which may exist
from time to time, Section 145 of the General Corporation Law of Delaware shall,
for the purposes of this Section 6, be interpreted as follows: an "other
enterprise" shall be deemed to include such an employee benefit plan, including
without limitation, any plan of the corporation which is governed by the Act of
Congress entitled "Employee Retirement Income Security Act of 1974," as amended
from time to time; the corporation shall be deemed to have requested a person to
serve an employee benefit plan where the performance by such person of his or
her duties to the corporation also imposes duties on, or otherwise involves
services by, such person to the plan or participants or beneficiaries of the
plan; excise taxes assessed on a person with respect to an employee benefit plan
pursuant to such Act of Congress shall be deemed "fines."

     Section 7.       The corporation shall indemnify its directors to the
fullest extent not prohibited by the California General Corporation Law;
PROVIDED, HOWEVER, that the corporation shall not be required to indemnify any
director in connection with any proceeding (or part thereof) initiated by such
person or any proceeding by such person against the corporation or its
directors, officers, employees or other agents unless (i) such indemnification
is expressly required to be made by law, (ii) the proceeding was authorized by
the board of directors of the corporation or (iii) such indemnification is
provided by the corporation, in its sole discretion, pursuant to the powers
vested in the corporation under the California General Corporation Law.

     The corporation shall have power to indemnify its officers, employees and
other agents as set forth in the California General Corporation Law.


                                      -21-
<PAGE>

     Promptly after receipt of a request for indemnification hereunder (and in
any event within 90 days thereof) a reasonable, good faith determination as to
whether indemnification of the director is proper under the circumstances
because each director has met the applicable standard of care shall be made by:
(i) a majority vote of a quorum consisting of directors who are not parties to
such proceeding; (ii) if such quorum is not obtainable, by independent legal
counsel in a written opinion; or (iii) approval or ratification by the
affirmative vote of a majority of the shares of this corporation represented and
voting at a duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least a majority of the required quorum) or by
written consent of a majority of the outstanding shares entitled to vote; where
in each case the shares owned by the person to be indemnified shall not be
considered entitled to vote thereon.

     For purposes of any determination under this bylaw, a director shall be
deemed to have acted in good faith and in a manner he or she reasonably believed
to be in the best interests of the corporation and its stockholders, and, with
respect to any criminal action or proceeding, to have had no reasonable cause to
believe that his or her conduct was unlawful, if his or her action is based on
information, opinions, reports and statements, including financial statements
and other financial data, in each case prepared or presented by:  (i) one or
more officers or employees of the corporation whom the director believed to be
reliable and competent in the matters presented; (ii) counsel, independent
accountants or other persons as to matters which the director believed to be
within such person's professional competence; and (iii) a committee of the Board
upon which such director does not serve, as to matters within such committee's
designated


                                      -22-
<PAGE>

authority, which committee the director believes to merit confidence; so long
as, in each case, the director acts without knowledge that would cause such
reliance to be unwarranted.

     The termination of any proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he or she reasonably believed to be in the best interests of the
corporation and its stockholders or that he or she had reasonable cause to
believe that his or her conduct was unlawful.

     The provisions of the preceding two paragraphs shall not be deemed to be
exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth by the
California General Corporation Law.

     The corporation shall advance, prior to the final disposition of any
proceeding, promptly following request therefor, all expenses incurred by any
director in connection with such proceeding upon receipt of an undertaking by or
on behalf of such person to repay said amounts if it shall be determined
ultimately that such person is not entitled to be indemnified under this bylaw
or otherwise.

     Without the necessity of entering into an express contract, all rights to
indemnification and advances to directors under this bylaw shall be deemed to be
contractual rights and be effective to the same extent and as if provided for in
a contract between the corporation and the director.  Any right to
indemnification or advances granted by this bylaw to a director shall be
enforceable by or on behalf of the person holding such right in the forum in
which the proceeding is or was pending or, if such


                                      -23-
<PAGE>

forum is not available or a determination is made that such forum is not
convenient, in any court of competent jurisdiction if (i) the claim for
indemnification or advances is denied, in whole or in part, or (ii) no
disposition of such claim is made within ninety (90) days of request therefor.
The claimant in such enforcement action, if successful in whole or in part,
shall be entitled to be paid also the expense of prosecuting his or her claim.
The corporation shall be entitled to raise as a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
connection with any proceeding in advance of its final disposition when the
required undertaking has been tendered to the corporation) that the claimant has
not met the standards of conduct that make it permissible under the California
General Corporation Law for the corporation to indemnify the claimant for the
amount claimed.  Neither the failure of the corporation (including its board of
directors, independent legal counsel or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because the claimant has met the
applicable standard of conduct set forth in the California General Corporation
Law, nor an actual determination by the corporation (including its board of
directors, independent legal counsel or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

     To the fullest extent permitted by the corporation's Certificate of
Incorporation and the California General Corporation Law, the rights conferred
on any person by this bylaw shall not be exclusive of any other right which such
person may have or hereafter acquire under any statute, provision of the
Certificate of Incorporation, bylaws,


                                      -24-
<PAGE>

agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his or her official capacity and as to action in another capacity
while holding office.  The corporation is specifically authorized to enter into
individual contracts with any or all of its directors, officers, employees or
agents respecting indemnification and advances, to the fullest extent permitted
by the California General Corporation Law and the corporation's Certificate of
Incorporation.

     The rights conferred on any person by this bylaw shall continue as to a
person who has ceased to be a director and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     The corporation, upon approval by the board of directors, may purchase
insurance on behalf of any person required or permitted to be indemnified
pursuant to this bylaw.  The corporation's obligation to provide indemnification
under this Section 7 shall be offset to the extent of any other source of
indemnification or any otherwise applicable insurance coverage under a policy
maintained by the corporation or any other person.

     Any repeal or modification of this bylaw shall only be prospective and
shall not affect the rights under this bylaw in effect at the time of the
alleged occurrence of any action or omission to act that is the cause of any
proceeding against any agent of the corporation.

     The corporation shall indemnify the directors and officers of the
corporation who serve at the request of the corporation as trustees, investment
managers or other fiduciaries of employee benefit plans to the fullest extent
permitted by the California General Corporation Law.


                                      -25-
<PAGE>

     If this bylaw or any portion hereof shall be invalidated on any ground by
any court of competent jurisdiction, then the corporation shall nevertheless
indemnify each director to the fullest extent permitted by any applicable
portion of this bylaw that shall not have been invalidated, or by any other
applicable law.

     For the purposes of this bylaw, the following definitions shall apply:

          (i)  The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement and appeal of any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative, arbitrative or
investigative.

          (ii) The term "expenses" shall be broadly construed and shall include,
without limitation, court costs, attorneys' fees, witness fees, fines, amounts
paid in settlement or judgment and any other costs and expenses of any nature or
kind incurred in connection with any proceeding, including expenses of
establishing a right to indemnification under this bylaw or any applicable law.

          (iii)     The term the "corporation" shall include, in addition to the
resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
directors, officers, and employees or agents, so that any person who is or was a
director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this bylaw with respect to the resulting or surviving corporation as he or
she


                                      -26-
<PAGE>

would have with respect to such constituent corporation if its separate
existence had continued.

          (iv) References to a "director," "officer," "employee," or "agent" of
the corporation shall include, without limitation, situations where such person
is serving at the request of the corporation as a director, officer, employee,
trustee or agent of another corporation, partnership, joint venture, trust or
other enterprise.

     Section 8.       In the event of any inconsistency between Section 6 and
Section 7 of this Article VII, the controlling Section as to any particular
issue with regard to any particular matter, shall be the one which authorizes
for the benefit of the agent or the other person in question the provision of
the fullest, promptest, most certain or otherwise most favorable indemnification
and/or advancement.

                                      VIII.

                                    AMENDMENT

     Section 1.       These bylaws may be altered, amended or repealed or new
bylaws may be adopted by the stockholders or by the Board of Directors, when
such power is conferred upon the Board of Directors by the certificate of
incorporation at any regular meeting of the stockholders or of the Board of
Directors or at any special meeting of the stockholders or of the Board of
Directors if notice of such alteration, amendment, repeal or adoption of new
bylaws be contained in the notice of such special meeting.  If the power to
adopt, amend or repeal bylaws is conferred upon the Board of Directors by the
certificate of incorporation it shall not divest or limit the power of the
stockholders to adopt, amend or repeal bylaws.

                           VISTA MEDICAL TECHNOLOGIES, INC.

of Dover, County of Kent, State of Delaware.

    Section 2.  OTHER OFFICES.  The corporation may also have offices at such
other places both within and without the State of Delaware as the Board of

require.

                                      ARTICLE II
                               MEETINGS OF STOCKHOLDERS

    Section 1.  PLACE OF MEETINGS.  All meetings of the stockholders for the
election of Directors shall be held in the City of Carlsbad, State of
California, at such place as may be fixed from time to time by the Board of
Directors, or at such other place either within or without the State of
California as shall be designated from time to time by the Board of Directors
and stated in the notice of the meeting.  Meetings of stockholders for any other
purpose may be held at such time and place, within or without the State of
California, as shall be stated in the notice of the meeting or in a duly
executed waiver of notice thereof.

    Section 2.   ANNUAL MEETING.

                   (a)  The annual meeting of the stockholders of the
corporation, for the purpose of election of Directors and for such other
business as may lawfully come before it, shall be held on such date and at such
time as may be designated from time to time by the Board of Directors.

                   (b)  At an annual meeting of the stockholders, only such
business shall be conducted as shall have been properly brought before the
meeting.  To be properly brought before an annual meeting, business must be:
(A) specified in the notice of meeting (or any supplement thereto) given by or
at the direction of the Board of Directors, (B) otherwise properly brought
before the meeting by or at the direction of the Board of Directors, or
(C) otherwise properly brought before the meeting by a stockholder.  For
business to be properly brought before an annual meeting by a stockholder, the
stockholder must have given timely notice thereof in writing to the Secretary of
the corporation.  To be timely, a stockholder's notice must be delivered to


<PAGE>

or mailed and received at the principal executive offices of the corporation no
later than the date specified in the corporation's proxy statement released to
stockholders in connection with the previous year's annual meeting of
stockholders, which date shall be not less than one hundred twenty (120)
calendar days in advance of the date of such proxy statement; provided, however,
that in the event that no annual meeting was held in the previous year or the
date of the annual meeting has been changed by more than thirty (30) days from
the date contemplated at the time of the previous year's proxy statement, notice
by the stockholder to be timely must be so received a reasonable time before the
solicitation is made.  A stockholder's notice to the Secretary shall set forth
as to each matter the stockholder proposes to bring before the annual meeting:
(i) a brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting,
(ii) the name and address, as they appear on the corporation's books, of the
stockholder proposing such business, (iii) the class and number of shares of the
corporation which are beneficially owned by the stockholder, (iv) any material
interest of the stockholder in such business and (v) any other information that
is required to be provided by the stockholder pursuant to Regulation 14A under
the Securities Exchange Act of 1934, as amended (the "1934 Act"), in such
stockholder's capacity as a proponent to a stockholder proposal.  In addition to
the foregoing, in order to include information with respect to a stockholder
proposal in the proxy statement and form of proxy for a stockholder's meeting,
stockholders must provide notice as required by the regulations promulgated
under the 1934 Act to the extent such regulations require notice that is
different from the notice required above.  Notwithstanding anything in these
Bylaws to the contrary, no business shall be conducted at any annual meeting
except in accordance with the procedures set forth in this paragraph (b) of this
Section 2.  The chairman of the annual meeting shall, if the facts warrant,
determine and declare at the meeting that business was not properly brought
before the meeting and in accordance with the provisions of this paragraph (b),
and, if he or she should so determine, the chairman shall so declare at the
meeting that any such business not properly brought before the meeting shall not
be transacted.

              (c)  Only persons who are nominated in accordance with the
procedures set forth in this paragraph (c) shall be eligible for election as
Directors.  Nominations of persons for election to the Board of Directors of the
corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors or by any stockholder of the corporation entitled to vote
in the election of Directors at the meeting who complies with the notice
procedures set forth in this paragraph (c).  Such nominations, other than those
made by or at the direction of the Board of Directors, shall be made pursuant to
timely notice in writing to the Secretary of the corporation in accordance with
the provisions of paragraph (b) of this Section 2.  Timely notice shall also be
given of any stockholder's intention to cumulate votes in the election of
Directors at a meeting if cumulative voting is available.  Such stockholder's
notice shall set forth (i) as to each person, if any, whom the stockholder
proposes to nominate for election or re-election as a Director:  (A) the name,
age, business address and residence address of such person, (B) the principal
occupation or employment of such person, (C) the class and number of shares of

entitled to vote thereat, present in person or represented by proxy, shall have
the power to adjourn the meeting from time to time, without notice other than
announcement at the meeting, until a quorum shall be present or represented.  At
such adjourned meeting at which a quorum shall be present or represented, any

                                      DIRECTORS

    Section 1.  CLASSES, NUMBER, TERM OF OFFICE AND QUALIFICATION.  At the next
annual meeting of stockholders following the adoption of these Bylaws, the
Directors shall be classified into three classes, as nearly equal in number as
possible as determined by the Board of Directors, with the term of office of the
first class to expire at the second annual meeting of stockholders following the
adoption of these Bylaws, the term of office of the second class to expire at
the third annual meeting of stockholders following the adoption of these Bylaws
and the term of office of the third class to expire at the fourth annual meeting
of stockholders following the adoption of these Bylaws.  At each annual meeting
of stockholders following such initial classification and election, Directors
elected to succeed those Directors whose terms expire shall be elected for a
term of office to expire at the third succeeding annual meeting of stockholders
after their election.  Additional directorships resulting from an increase in
the number of Directors shall be apportioned among the classes as equally as
possible as determined by the Board of Directors.  The number of Directors which
shall constitute the whole Board shall be fixed by resolution of the Board of
Directors, with the number initially fixed at seven (7).  The number of
Directors shall be determined by resolution of sixty-six and two-thirds percent
(66-2/3%) of the Directors then in office or by sixty-six and two-thirds percent
(66-2/3%) of the stockholders at the annual meeting of the stockholders, and
each Director elected shall hold office until his or her successor is elected
and qualified.  Directors need not be stockholders.

    Section 2.  VACANCIES.  Vacancies may be filled only by a two-thirds
majority of the Directors then in office or by a sole remaining Director.  Each
Director so chosen shall hold office until a successor is duly elected and shall
qualify or until his or her earlier death, resignation or removal.  If there are
no Directors in office, then an election of Directors may be held in the manner
provided by statute; provided, however, that each Director shall be elected by
an affirmative vote of at least two-thirds of the stockholders.  If, at the time
of filling any vacancy, the Directors then in office shall constitute less than
a majority of the whole Board (as constituted immediately prior to any such
increase), the Court of Chancery may, upon application of any stockholder or
stockholders holding at least ten percent of the total number of the shares at
the time outstanding having the right to vote for such Directors, summarily
order an election to be held to fill any such vacancies, or to replace the
Directors chosen by the Directors then in office.

    Section 3.  POWERS.  The business of the corporation shall be managed by or
under the direction of its Board of Directors which may exercise all such powers
of the corporation and do all such lawful acts and things as are not by statute
or by the Certificate of Incorporation, as amended, or by these Bylaws directed
or required to be exercised or done by the stockholders.

Chief Executive Officer, President or Secretary in like manner and on like
notice on the written request of two Directors unless the Board consists of only
one Director, in which case special meetings shall be called by the Chief
Executive Officer, President or Secretary in like manner and on like notice on
the written request of the sole Director.  A written waiver of notice, signed by
the person entitled thereto, whether before or after the time of the meeting
stated therein, shall be deemed equivalent to notice.

    Section 8.  QUORUM.  At all meetings of the Board a majority of the
Directors shall constitute a quorum for the transaction of business and the act
of a majority of the Directors present at any meeting at which there is a quorum
shall be the act of the Board of Directors, except as may be otherwise
specifically provided by these Bylaws, by statute or by the Certificate of
Incorporation, as amended.  If a quorum shall not be present at any meeting of
the Board of Directors, the Directors present thereat may adjourn the meeting
from time to time, without notice other than announcement at the meeting, until
a quorum shall be present.

    Section 9.  ACTION WITHOUT MEETING.  Unless otherwise restricted by the
Certificate of Incorporation, as amended, or these Bylaws, any action required

by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the Directors of the corporation.  The
Board may designate one or more Directors as alternate members of any committee,
who may replace any absent or disqualified member at any meeting of the
committee.

         In the absence of disqualification of a member of a committee, the
member or members thereof present at any meeting and not disqualified from
voting, whether or not he, she or they constitute a quorum, may unanimously
appoint another member of the Board of Directors to act at the meeting in the
place of any such absent or disqualified member.

         Any such committee, to the extent provided in the resolution of the
Board of Directors, shall have and may exercise all the powers and authority of
the Board of Directors in the management of the business and affairs of the
corporation, and may authorize the seal of the corporation to be affixed to all
papers which may require it; but no such committee shall have the power or
authority in reference to amending the Certificate of Incorporation, as amended,
adopting an agreement of merger or consolidation, recommending to the
stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, recommending to the stockholders a
dissolution of the corporation or a revocation of a dissolution, or amending the
Bylaws of the corporation; and, unless the resolution or the Certificate of
Incorporation, as amended, expressly so provide, no such committee shall have
the power or authority to declare a dividend or to authorize the issuance of
stock.  Such committee or committees shall have such name or names as may be
determined from time to time by resolution adopted by the Board of Directors.

         Each committee shall keep regular minutes of its meetings and report
the same to the Board of Directors when required.

    Section 12.  FEES AND COMPENSATION.  Unless otherwise restricted by the
Certificate of Incorporation, as amended, or these Bylaws, the Board of

Directors may be paid their expenses, if any, of attendance at each meeting of
the Board of Directors and may be paid a fixed sum for attendance at each
meeting of the Board of Directors or a stated salary as Director.  No such
payment shall preclude any Director from serving the corporation in any other
capacity and receiving compensation therefor.  Members of special or standing
committees may be allowed like compensation for attending committee meetings.

however, that the corporation may limit the extent of such indemnification by
individual contracts with its Directors and executive officers; and, provided,
further, that the corporation shall not be required to indemnify any Director or
executive officer in connection with any proceeding (or part thereof) initiated
by such person or any proceeding by such person against the corporation or its
Directors, officers, employees or other agents unless (i) such indemnification
is expressly required to be made by law, (ii) the proceeding was authorized by
the Board of Directors of the corporation and (iii) such indemnification is
provided by the corporation, in its sole discretion, pursuant to the powers
vested in the corporation under the Delaware General Corporation Law.

    Section 2.  INDEMNIFICATION OF OTHER OFFICERS, EMPLOYEES AND OTHER AGENTS.
The corporation shall have power to indemnify its other officers, employees and
other agents as set forth in the Delaware General Corporation Law.

    Section 3.  GOOD FAITH.

         (a)  For purposes of any determination under this Bylaw, a Director or
executive officer shall be deemed to have acted in good faith and in a manner he
or she reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, to have had
no reasonable cause to believe that his or her conduct was unlawful, if his or
her action is based on information, opinions, reports and statements, including
financial statements and other financial data, in each case prepared or
presented by:

              (1)  one or more officers or employees of the
         corporation whom the Director or executive officer believed
         to be reliable and competent in the matters presented;

              (2)  counsel, independent accountants or other persons
         as to matters which the Director or executive officer
         believed to be within such person's professional competence;
         and

              (3)  with respect to a Director, a committee of the
         Board upon which such Director does not serve, as to matters
         within such committee's designated authority, which
         committee the Director believes to merit confidence; so long
         as, in each case, the Director or executive officer acts
         without knowledge that would cause such reliance to be
         unwarranted.


                                         -13-

         (b)  The termination of any proceeding by judgment, order, settlement,
conviction or upon a plea of nolo contendere or its equivalent shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which such person reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal proceeding, that
such person had reasonable cause to believe that his or her consent was
unlawful.

         (c)  The provisions of this Section 3 shall not be deemed to be
exclusive or to limit in any way the circumstances in which a person may be
deemed to have met the applicable standard of conduct set forth by the Delaware
General Corporation Law.

    Section 4.  EXPENSES.  The corporation shall advance, prior to the final
disposition of any proceeding, promptly following request therefor, all expenses
incurred by any Director or executive officer in connection with such proceeding
upon receipt of an undertaking by or on behalf of such person to repay said
amounts if it should be determined ultimately that such person is not entitled
to be indemnified under this Bylaw or otherwise.

         Notwithstanding the foregoing, unless otherwise determined pursuant to
Section 4 of this Bylaw, no advance shall be made by the corporation if a
determination is reasonably and promptly made (i) by the Board of Directors by a
majority vote of a quorum consisting of Directors who were not parties to the
proceeding or (ii) if such quorum is not obtainable, or, even if obtainable, a
quorum of disinterested Directors so directs, by independent legal counsel in a
written opinion, that the facts known to the decision-making party at the time
such determination is made demonstrate clearly and convincingly that such person
acted in bad faith or in a manner that such person did not believe to be in or
not opposed to the best interests of the corporation.

    Section 5.  ENFORCEMENT.  Without the necessity of entering into an express
contract, all rights to indemnification and advances to Directors and executive
officers under this Bylaw shall be deemed to be contractual rights and be
effective to the same extent and as if provided for in a contract between the
corporation and the Director or executive officer.  Any right to indemnification
or advances granted by this Bylaw to a Director or executive officer shall be
enforceable by or on behalf of the person holding such right in any court of
competent jurisdiction if (i) the claim for indemnification or advances is
denied, in whole or in part or (ii) no disposition of such claim is made within
ninety (90) days of request therefor.  The claimant in such enforcement action,
if successful in whole or in part, shall be entitled to be paid also the expense
of prosecuting such claim.  The corporation shall be entitled to raise as a
defense to any such action that the claimant has not met the standards of
conduct that make it permissible under the Delaware General Corporation Law for
the corporation to indemnify the claimant for the amount claimed.  Neither the
failure of the corporation (including its Board of Directors, independent legal
counsel or its stockholders) to have made a determination prior to the
commencement of such action that indemnification of the claimant is proper in
the circumstances because he or she has met the applicable standard of conduct
set forth in the Delaware General Corporation Law, nor an actual determination
by the


                                         -14-


<PAGE>

corporation (including its Board of Directors, independent legal counsel or its
stockholders) that the claimant has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that the claimant has
not met the applicable standard of conduct.

    Section 6.  NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on any person
by this Bylaw shall not be exclusive of any other right which such person may
have or hereafter acquire under any statute, provision of the Certificate of
Incorporation, as amended, Bylaws, agreement, vote of stockholders or
disinterested Directors or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding office.
The corporation is specifically authorized to enter into individual contracts
with any or all of its Directors, officers, employees or agents respecting
indemnification and advances, to the fullest extent not prohibited by the
Delaware General Corporation Law.

    Section 7.  SURVIVAL OF RIGHTS.  The rights conferred on any person by this
Bylaw shall continue as to a person who has ceased to be a Director, officer,
employee or other agent and shall inure to the benefit of the heirs, executors
and administrators of such a person.

    Section 8.  INSURANCE.  To the fullest extent permitted by the Delaware
General Corporation Law, the corporation, upon approval by the Board of
Directors, may purchase insurance on behalf of any person required or permitted
to be indemnified pursuant to this Bylaw.

    Section 9.  AMENDMENTS.  Any repeal or modification of this Bylaw shall
only be prospective and shall not affect the rights under this Bylaw in effect
at the time of the alleged occurrence of any action or omission to act that is
the cause of any proceeding against any agent of the corporation.

    Section 10.  SAVING CLAUSE.  If this Bylaw or any portion hereof shall be
invalidated on any ground by any court of competent jurisdiction, then the
corporation shall nevertheless indemnify each Director and executive officer to
the full extent not prohibited by any applicable portion of this Bylaw that
shall not have been invalidated or by any other applicable law.

    Section 11.  CERTAIN DEFINITIONS.  For the purposes of this Bylaw, the
following definitions shall apply:

              (a)  The term "proceeding" shall be broadly construed and shall
include, without limitation, the investigation, preparation, prosecution,
defense, settlement, arbitration and appeal of, and the giving of the testimony
in, any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative.

resulting corporation, any constituent corporation (including any constituent of
a constituent) absorbed in a consolidation or merger which, if its separate
existence had continued, would have had power and authority to indemnify its
Directors, officers, and employees or agents, so that any person who is or was a
Director, officer, employee or agent of such constituent corporation, or is or
was serving at the request of such constituent corporation as a Director,
officer, employee or agent of another corporation, partnership, joint venture,
trust or other enterprise, shall stand in the same position under the provisions
of this Bylaw with respect to the resulting or surviving corporation as such
person would have with respect to such constituent corporation if its separate
existence had continued.

              (d)  References to a "Director," "officer," "employee," or
"agent" of the corporation shall include, without limitation, situations where
such person is serving at the request of the corporation as a Director, officer,
employee, trustee or agent of another corporation, partnership, joint venture,
trust or other enterprise.

              (e)  References to "other enterprises" shall include employee
benefit plans; references to "fines" shall include any excise taxes assessed on
a person with respect to an employee benefit plan; and references to "serving at
the request of the corporation" shall include any service as a Director,
officer, employee or agent of the corporation which imposes duties on, or
involves services by, such Director, officer, employee, or agent with respect to
an employee benefit plan, its participants, or beneficiaries; and a person who
acted in good faith and in a manner such person reasonably believed to be in the
interest of the participants and beneficiaries of an employee benefit plan shall
be deemed to have acted in a manner "not opposed to the best interests of the
corporation" as referred to in this Bylaw.

                                     ARTICLE VIII
                                  LOANS TO OFFICERS

    Section 1.  LOANS TO OFFICERS.  The corporation may lend money to, or
guarantee any obligation of, or otherwise assist any officer or other employee
of the corporation or of its subsidiaries, including any officer or employee who
is a Director of the Corporation or its subsidiaries, whenever, in the judgment
of the Board of Directors, such loan, guarantee or assistance may reasonably be
expected to benefit the corporation.  The loan, guarantee or other assistance
may be with or without interest and may be unsecured, or secured in such manner
as the Board of Directors shall approve, including, without limitation, a pledge
of shares of stock of the corporation.  Nothing in this Bylaw shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

proper as a reserve or reserves to meet contingencies, or for equalizing
dividends, or for repairing or maintaining any property of the corporation, or

                   (a)  Except as otherwise set forth in Section 9 of Article

Directors shall also have the power, if such power is conferred upon the Board
of Directors by the Certificate of Incorporation, as amended, to adopt, amend or
repeal Bylaws by a vote of the majority of the Board of Directors unless a
greater or different vote is required pursuant to the provisions of the Bylaws,
the Certificate of Incorporation or any applicable provision of law.

                   (b)  Notwithstanding any other provisions of these Bylaws or
any provision of law which might otherwise permit a lesser vote or no vote, but
in addition to

<PAGE>

any affirmative vote of the holders of any particular class or series of the

Carlsbad, California 92008

    Re:  3,500,000 SHARES OF COMMON STOCK OF VISTA MEDICAL TECHNOLOGIES, INC.

Ladies and Gentlemen:

    We have acted as counsel to Vista Medical Technologies, Inc., a Delaware
corporation (the "Company"), in connection with the proposed issuance and sale
by the Company of 3,500,000 shares of the Company's Common Stock (the "Shares"),
pursuant to the Company's Registration Statement on Form S-1 filed on March __,
1997, as amended by Amendment No. 1 filed on _________, 1997, Amendment No. 2
filed on ________, 1997, and the Rule 462(b) Registration Statement filed on
_______, 1997 (the "Registration Statement").

    In connection with this opinion, we have examined and relied upon the
Registration Statement and related Prospectus, the Company's Amended and
Restated Certificate of Incorporation, as amended, the Second Restated
Certificate of Incorporation which the Registration Statement contemplates will
be filed before the sale and issuance of the Shares, the Company's bylaws, and
originals, or copies certified to our satisfaction, of such other records,
documents, certificates, memoranda and other instruments as in our judgment are
necessary or appropriate to enable us to render the opinion expressed below.

    On the basis of the foregoing, and in reliance thereon, we are of the
opinion that the Shares, if, as and when sold and issued in accordance with the
Registration Statement and Prospectus (as amended and supplemented through the
date of issuance), will be validly issued, fully paid and nonassessable.  

    We consent to the reference to our firm under the caption "Legal Matters"
in the Registration Statement and related Prospectus and to the filing of this
opinion as an exhibit to the Registration Statement.


                        Very truly yours,

                        /s/ Brobeck, Phleger & Harrison LLP

                                      ARTICLE II

                                 ASSUMED LIABILITIES

         SECTION 2.1    ASSUMED LIABILITIES.  Subject to Section 2.2 hereof,
Purchaser hereby agrees at the Time of Closing to assume, satisfy or perform
when due those liabilities and obligations of Seller arising after the Time of
Closing under the Contracts and Permits.  The liabilities assumed hereunder by
the Purchaser are hereinafter called the "Assumed Liabilities".

         SECTION 2.2    LIABILITIES NOT ASSUMED. Other than the Assumed
Liabilities, Purchaser shall not assume, nor shall Purchaser or any affiliate of
Purchaser, be deemed to have assumed or guaranteed, any other liability or
obligation of any nature of Seller, or claims of such liability or obligation,
whether accrued, matured or unmatured, liquidated or unliquidated, fixed or
contingent, known or unknown arising out of (i) acts or occurrences, or related
to any of the Assets, prior to the Time of Closing, (ii) any of Seller's
products sold by Seller prior to the Time of Closing, or (iii) any other
liability or obligation of Seller (collectively, the "Unassumed Liabilities").
In the event Purchaser is deemed responsible for any Unassumed Liabilities,
Seller shall indemnify Purchaser pursuant to Section 5.15 of this Agreement from
and against all losses incurred by Purchaser in satisfying such liabilities or
obligations.

                                     ARTICLE III

                                    PURCHASE PRICE

         SECTION 3.1    CONSIDERATION.  Upon the terms and subject to the
conditions contained in this Agreement, in consideration for the Assets to be
given by Seller and in full payment therefor, Purchaser will pay, or cause to be
paid, the purchase price set forth in Section 3.2 hereof to Seller, subject to
adjustment in accordance with the provisions set forth herein, and Purchaser
will assume all of the Assumed Liabilities.

         SECTION 3.2    PAYMENT OF PURCHASE PRICE.  The consideration
("Purchase Price") to be paid by Purchaser to Seller for the Business and the
other forms of consideration to be given by Seller shall be:

              (a)  (i)  One Hundred Fifty Four Thousand Five Hundred Eighty One
(154,581) shares of Purchaser's Non-Voting Series A-3 Preferred Stock (the
"Shares") and (ii) $25,000 payable by check or wire transfer.  The $25,000
payable pursuant to this Section 3.2(a)(ii) shall be credited as $30,000 against
any amounts owed to Seller or its assignees pursuant to Section 3.2(b) below;


                                          3.


<PAGE>

              (b)  (i) Fifty percent (50%) of the net revenues from the sale by
Purchaser of up to twenty (20) of Seller's 3D Scope Systems or components
thereof or (ii) Fifty percent (50%) of the net revenues from all sales by
Purchaser of Seller's 3D Scope Systems or components thereof made prior to
December 3, 1996, whichever shall occur first.    The net revenue calculation
shall be based on the cash receipts by Purchaser for the sale of Seller's 3D
Scope Systems constructed primarily from Inventory or sales of components, less
(i) Purchaser's documented costs in placing such 3D Scope Systems or components
into salable condition, calculated in accordance with generally accepted
accounting procedures and consistent with Purchaser's existing business
practices, and (ii) that portion of the sales proceeds of 3D Scope Systems or
components thereof placed in the Warranty Withholding Account (as defined
below).  Purchaser shall be entitled to withhold from Seller or its assignees an
amount equal to 10% of the sales proceeds of each 3D Scope System or component
to cover warranty costs (the "Warranty Withholding Account"), subject to
disbursement to Seller or its assignees in accordance with Section 3.2(c) (ii)
below.  Purchaser shall be entitled to reimburse itself from the Warranty
Withholding Account for any warranty costs incurred by Purchaser in connection
with the 3D Scope Systems or components. In the event of Seller's dissolution,
Seller may assign its rights under this Section 3.2(b) and shall deliver to
Purchaser a certificate signed by Seller's chief executive officer setting forth
the name and address of any such assignee and the percentage of any such sums
distributed to which such assignee is entitled; provided, however, that any such
assignee must agree to be subject to Section 3.3 below.

              (c)  (i) Purchaser shall disburse to Seller or its assignees any
sums owed pursuant to Section 3.2(b)(i) or (ii), on a quarterly basis within 30
days of the end of Purchaser's quarterly accounting period; and

                   (ii) Purchaser shall disburse sums from the Warranty
Withholding Account to Seller or its assignees as the applicable warranty period
for each 3D Scope System lapses less any documented warranty costs incurred in
connection with 3D Scope Systems (1) constructed primarily from Inventory, and
(2) sold by Seller prior to the Time of Closing.

              (d)  Seller or, in the event of Seller's liquidation and
dissolution, each of the distributees of Seller's remaining assets
("Distributees"), may elect to receive any sums owed pursuant to Section 3.2(b)
in the form of shares of Purchaser's Non-Voting Series A-3 Preferred Stock by
delivering to Purchaser within 10 days of the end of Purchaser's quarterly
accounting period notice of such election; provided that, such election may be
conditioned upon the determination of the Fair Market Value of the Non-Voting
Series A-3 Preferred Stock, as provided below.  The number of shares to be
delivered to Seller (or such Distributees) shall be the quotient obtained by
dividing (i) the product of the cash amount payable to such Stockholder
multiplied by 1.33, by (ii) the Fair Market Value of Purchaser's preferred
stock, and rounding such quotient to the nearest whole share.  The Fair Market
Value of Purchaser's preferred stock shall be as


                                          4.


<PAGE>

determined in good faith by Purchaser's board of directors, but in no event
shall it be less than the price per share received by Purchaser in its latest
round of equity financing.  If Seller or its Distributees holding a majority in
interest of the Non-Voting Series A-3 Preferred Stock to be distributed pursuant
to this Section 3.2(d) shall disagree with the Purchaser's determination of the
Fair Market Value of the Non-Voting Series A-3 Preferred Stock, then Purchaser
and Seller or such Distributees, as the case may be, shall appoint an
independent third-party appraiser to determine the Fair Market Value of the
Series A-3 Preferred Stock.  Any such sums paid in shares of preferred stock
shall be subject to the receipt by Purchaser from Seller or its assignees of the
representations and warranties contained in Sections 4.1(w) through 4.1(z).

              (e)  Any or all of the Assets may be transferred to the Purchaser
to be held in escrow pending the Time of Closing; provided, however, that
Purchaser shall not be liable for any damage of loss to any of such Assets
except as may result from Purchaser's own negligence.

         SECTION 3.3    OFFSET.  (a) Any payments to be made to Seller pursuant
to Section 3.2(b) shall be subject to offset, and shall be accordingly reduced
to the extent of any payments made by Purchaser in connection with any and all
actions, causes of action, claims, demands, costs, liabilities, expenses, and
damages incurred by Purchaser (collectively, "Damages") arising out of or
related to the actual breach of any representation or warranty or the
nonperformance of any of Seller's covenants or agreements contained in this
Agreement or any assertion against Purchaser by any third party of any debt,
liability, obligation, or commitment of Seller not otherwise assumed by
Purchaser under this Agreement for which Purchaser becomes liable.

         (b)  Upon receipt by Seller, or its designated representative, of a
certificate signed by any officer of Purchaser (an "Officer's Certificate"):

                   (i)  stating that Damages exist, and

                   (ii)  specifying in reasonable detail the individual items
              of such Damages included in the amount so stated, the date each
              such item was paid, or properly accrued or arose, the nature of
              the misrepresentation, breach of warranty or claim to which such
              item is related,

Purchaser shall be entitled, subject to the provisions of Section 3.4(c) hereof,
to withhold from Seller without any liability therefor, an amount equal to the
value of such Damages.

           (c)   (i)    Seller, or its designated representative, shall have
thirty (30) days from the date of mailing to Seller of any such Officer's
Certificate to make written objection to Purchaser of the nature and amount of
any such Damages.  In the event Seller shall so object, Purchaser shall have
thirty (30) days to respond in writing to the


                                          5.


<PAGE>

objection of Seller.  If after such thirty (30) day period there remains a
dispute as to any claims, Seller and Purchaser shall attempt in good faith for
thirty (30) days to agree upon the rights of the respective parties with respect
to each of such claims.  If Seller and Purchaser should so agree, a memorandum
setting forth such agreement shall be prepared and signed by both parties.
Purchaser and Seller shall be entitled to rely on any such memorandum and act in
accordance with the terms thereof.

               (ii)     If no such agreement can be reached after good faith
negotiation, either Purchaser or Seller may, by written notice to the other,
demand arbitration of the matter unless the amount of the damage or loss is at
issue in pending litigation with a third party, in which event arbitration shall
not be commenced until such amount is ascertained or both parties agree to
arbitration; and in either such event the matter shall be settled by arbitration
conducted by three arbitrators.  Within fifteen (15) days after such written
notice is sent, Purchaser and Seller shall each select one arbitrator, and the
two arbitrators so selected shall select a third arbitrator.  The decision of
the arbitrators as to the validity and amount of any claim in such Officer's
Certificate shall be binding and conclusive upon the parties to this Agreement,
and notwithstanding anything in this Section 3.4, Purchaser shall be entitled to
act in accordance with such decision and make or withhold payments to Seller in
accordance therewith.

              (iii)     Judgment upon any award rendered by the arbitrators may
be entered in any court having jurisdiction.  Any such arbitration shall be held
in San Diego County, California under the commercial rules then in effect of the
American Arbitration Association.  For purposes of this Section 3.4(c), in any
arbitration hereunder in which any claim or the amount thereof stated in the
Officer's Certificate is at issue, Purchaser shall be deemed to be the
Non-Prevailing Party unless the arbitrators award Purchaser more than one-half
(1/2) of the amount in dispute, plus any amounts not in dispute; otherwise,
Seller shall be deemed to be the Non-Prevailing Party.  The Non-Prevailing Party
to an arbitration shall pay its own expenses, the fees of each arbitrator, the
administrative fee of the American Arbitration Association, and the expenses,
including with limitation, attorneys' fees and costs, incurred by the other
party to the arbitration.


                                      ARTICLE IV

                            REPRESENTATIONS AND WARRANTIES

         SECTION 4.1    REPRESENTATIONS AND WARRANTIES OF SELLER.  Seller
hereby represents and warrants to Purchaser that:

              (a)  ORGANIZATION OF SELLER.  Seller is a corporation duly
organized, validly existing and in good standing under the laws of the state of
Delaware, and has all requisite power and authority to own and operate the
Business in the places where the Business is now conducted and to directly own,
lease, and operate the Assets.


                                          6.


<PAGE>

Seller is duly qualified or licensed to do business as a corporation in each of
the jurisdictions in which the nature of the Business or location of properties
related to the Business requires such qualification or licensing and where the
failure to be so qualified would have a material adverse effect on the Business.

              (b)  AUTHORIZATION OF SELLER.  Seller has full power and
authority to enter into this Agreement, to perform its obligations hereunder,
and to consummate the transactions contemplated hereby, including, without
limitation, the execution and delivery of this Agreement, bills of sale,
assignments and assumptions, novations and other instruments evidencing the
conveyance of the Assets or delivered in accordance with Section 6.2 hereunder
(the "Closing Documents").  Seller has taken all necessary and appropriate
corporate action, including obtaining all necessary board and shareholder
consents, with respect to the execution and delivery of this Agreement and the
Closing Documents.  This Agreement constitutes the valid and binding obligation
of Seller enforceable in accordance with its terms, subject to bankruptcy,
insolvency, reorganization, moratorium, and other similar laws affecting the
rights and remedies of creditors and subject to the general principles of
equity.

              (c)  FINANCIAL INFORMATION.  Seller has delivered to Purchaser
its audited balance sheets and related statements of operations and cash flows
of the Seller at and for the fiscal year ended March 3, 1994 and unaudited
balance sheets and related statements of operations at and for the period ended
May 3, 1995 of the Business (collectively, the "Financial Statements").  Each
Financial Statement is complete and correct in all material respects and has
been or will be as of the Time of Closing, prepared on a consistent basis
throughout the periods indicated and with each other and prepared in accordance
with generally accepted accounting principles ("GAAP") (except that the interim
statements (i) are prepared in a manner including all material adjustments,
consisting only of normal recurring accruals necessary for a fair presentation
of the results for these periods, (ii) are not necessarily indicative of the
results for the full fiscal year and (iii) are unaudited and do not include
footnotes).  The Financial Statements fairly describe the financial condition
and operating results of Seller as of the dates, and for the periods, indicated
therein.

              (d)  RETURNS.  Except as set forth on Schedule 4.1(d) Seller has
not had any of its products related to the Business returned by a purchaser or
user thereof, other than for minor, nonrecurring warranty problems.  Seller is
not aware of any (i) pending warranty claims for such products, (ii) right to
return such products (other than units under customary evaluation terms), or
(iii) evaluation units expected to be returned after their evaluation period.

              (e)  ABSENCE OF CERTAIN CHANGES AND EVENTS.  Since May 3, 1995,
there has not been:


                                          7.


<PAGE>

                     (i)     Any material adverse change in the assets or
liabilities of Seller;

                    (ii)     Any sale, lease, or disposition of, or any
agreement to sell, lease, or dispose of any of the Assets other than pursuant to
this Agreement;

                   (iii)     Any modification, waiver, change, amendment,
release, rescission, accord and satisfaction, or termination of, or with respect
to, any term, condition, or provision of any material Contract relating to or
affecting the Business, the Assets, or the Assumed Liabilities, other than any
satisfaction by performance in accordance with the terms thereof in the usual
and ordinary course of Business;

                    (iv)     Any borrowing or lending of money by Seller,
including to or from its shareholders, but excluding for this purpose sales made
on ordinary trade terms; or

                     (v)     Any other event or condition of any character that
has had a material adverse effect, or may reasonably be expected to have a
material adverse effect, on the Assets or the Business.

              (f)  UNDISCLOSED LIABILITIES.  There are no debts, claims,
liabilities, or obligations with respect to the Business (except as incurred in
the ordinary course of business since the date of the Financial Statements) or
to which the Assets are subject, liquidated, unliquidated, accrued, absolute,
contingent, or otherwise, that are not identified in the Financial Statements.

              (g)  INVENTORY.    Schedule 1.1(b) hereto lists all of Seller's
inventory other than excess, unused or obsolete items.  All items included in
the Inventory are the property of Seller and, as of the Time of Closing, are
free and clear of any mortgage, pledge, lien, security interest or other
encumbrance.

              (h)  TAXES.  Seller has completed and duly filed (or has received
an extension of time to file and will complete and file in such extended time)
in correct form with the appropriate United States, state and local governmental
agencies and with the appropriate foreign countries and political subdivisions
thereof, all Tax (as hereinafter defined) returns and reports required to be
filed; all of such returns and reports are accurate and complete; and Seller has
paid in full or made adequate provisions on its financial statements for all
Taxes, assessments or deficiencies shown to be due on such Tax returns and
reports or claimed to be due by any taxing authority or otherwise due or owing.
Seller has made all payments of estimated income Tax through the date hereof and
all withholdings of Tax required to be made under all applicable United States,
foreign, state and local tax laws and regulations, and such withholdings have
either been paid to the respective governmental agencies or set aside in
accounts for such purpose or accrued, reserved against and entered upon the
books of such company.  The Assets are not subject to any liens for Taxes,
except liens for current


                                          8.


<PAGE>

Taxes not yet due.  There is no contract, agreement, plan or arrangement,
including but not limited to the provisions of this Agreement, covering any
current or former employee of the Business that, individually or collectively,
could give rise to the payment of any amount that would not be deductible
pursuant to Section 280G or Section 162 of the Code.

                   For purposes of this Agreement, "Tax" (and, with correlative
meaning, "Taxes" and "Taxable") means (i) any net income, alternative or add-on
minimum tax, gross income, gross receipts, sales, use, ad valorem, transfer,
franchise, profits, license, withholding, payroll, employment, excise,
severance, stamp, occupation, premium, property, environmental or windfall
profit tax, custom, duty or other tax, governmental fee or other like assessment
or charge of any kind whatsoever, together with any interest or any penalty,
addition to tax or additional amount imposed by any governmental, regulatory or
administrative entity or agency responsible for the imposition of any such tax
(domestic or foreign), (ii) any liability for the payment of any amounts of the
type described in (i) as a result of being a member of an affiliated,
consolidated, combined, unitary or other group for any Taxable period and
(iii) any liability for the payment of any amounts of the type described in (i)
or (ii) as a result of any express or implied obligation to indemnify any other
person.

              (i)  COMPLIANCE WITH LAW.  Seller has complied and is in
compliance in all material respects with all applicable federal, state, and, to
the best of Seller's knowledge, local laws, statutes, licensing requirements,
rules, and regulations, and judicial or administrative decisions applicable to
the Business.  There is no order issued, investigation, or proceeding pending
or, to the best of Seller's knowledge, threatened, or notice served with respect
to any violation of any law, ordinance, order, writ, decree, rule, or regulation
issued by any federal, state, local, or foreign court or governmental or
regulatory agency or instrumentality applicable to the Business.

              (j)  GOVERNMENTAL CONSENTS.  No consent, approval, order, or
authorization of, or registration, qualification, designation, declaration, or
filing with any federal, state, local, or provincial governmental authority on
the part of Seller is required in connection with the consummation of the
transactions contemplated hereunder.

              (k)  PROPRIETARY RIGHTS.   Set forth on Schedule 1.1(e) hereto is
a complete and accurate list and brief description of all Proprietary Rights
owned or held by Seller used in the Business.  Except as set forth on Schedule
4.1(k), Seller has complete and undisputed title and ownership of or adequate
rights (license or otherwise) to utilize all Proprietary Rights necessary for or
used in the Business, without any conflict with or infringement of the rights of
others.

              Except as set forth on Schedule 4.1(k), there are no outstanding
options, licenses, or agreements of any kind relating to the foregoing, nor is
Seller bound by or a party to any options, licenses or agreements of any kind
with respect to the


                                          9.


<PAGE>

proprietary rights of any other person or entity.  Seller has not received any
communications nor is it aware of any entity alleging that Seller has violated
or, by conducting the Business as currently conducted, would violate any
proprietary rights of any other person or entity.  Seller is not aware that any
of its employees or consultants associated with the Business is obligated under
any contract (including licenses, covenants or commitments of any nature) or
other agreement, or subject to any judgment, decree or order of any court or
administrative agency, that would interfere with the use of his or her best
efforts to promote the interests of Seller or that would conflict with the
Business as now conducted.  Neither the execution nor delivery of this Agreement
nor the carrying on of the Business by its employees or consultants will
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, any contract, covenant or instrument of which
Seller is aware under which any of such employees or consultants or Seller is

                   (B)  Seller has performed all of its obligations under the
terms of each Contract and is not in default thereunder.  No event or omission
has occurred which but for the giving of notice or lapse of time or both would
constitute a default by any party thereto under any such Contract, where such
default by any party could have a material adverse effect on the Business or the
Assets.  Each such Contract is valid and binding on all parties thereto and in
full force and effect.  Seller has received no notice of default, cancellation,
or termination in connection with any such Contract.

"Contracts Requiring Novation or Consent to Assignment").  Such list is
complete, accurate and includes every Contract which, if no novation occurs to
make Purchaser a party thereto or if no consent to assignment is obtained, would
have a material adverse effect on

such Liens.

Purchaser will obtain good and marketable title to the Assets, free and clear of
all Liens except for Permitted Encumbrances.

              (o)  NO CONFLICT OR DEFAULT.  Neither the execution and delivery
of this Agreement nor compliance with the terms and provisions hereof, including

agreement, deed, contract, mortgage, indenture, writ, order, decree, legal
obligation, or instrument to which Seller is a party or by which it or any of

thereof (other than to the Distributees as contemplated by Section 6.3(a)
hereof).  Seller understands that the Shares (and any Common Stock issuable upon
conversation of the Shares) to be purchased have not been registered under the

of a public market for the shares, the availability of certain current public
information about Purchaser, the resale occurring not less than two years after

judgment that the pendency of any lawsuit or the institution or threat of any
governmental or administrative action, investigation or inquiry which questions
the validity or the legality of the transactions contemplated hereby or which

be deemed to be without merit; or

lawsuit, action, investigation or inquiry may be deemed to be without merit; or

         (d)  In the event of termination and abandonment by the Board of
Directors of Purchaser or by the Board of Directors of Seller, or both, pursuant

    hereof, to the party furnishing the same;

                    (ii)       No such termination shall effect the obligations
    under Section 8.12 hereof which shall survive termination of this
    Agreement; and

                   (iii)     All parties hereto shall bear their own costs
    associated with this Agreement and all transactions described herein and
    the parties hereto shall have no further obligation or liability to the
    other parties except as stated in this Section 8.11.

         SECTION 8.12   EXPENSE REIMBURSEMENT;  (a) In the event that this
Agreement is terminated by Purchaser (so long as Purchaser has not willfully

AST Inventory Items
July 10, 1995

CAMERA SYSTEMS

We catalogued all of the primary subassemblies and assessed their readiness for
release.  Our assessments of the state of the subassemblies is based strictly on
the test sheets and AST reports that we found.  We did no evaluation of our own.
We then matched the subassemblies and came up with a tally of the integrated
systems.  The list from this process is included here.

We rated the combined systems as follows:

- -   Level A (qty. 6 units) just need to be tested.
- -   Level B (qty. 5 units) are only in need of final test and alignment.
- -   Level C (qty. 8 units) have a stated problem that we should either be able
    to live with or optimize out of the systems with a little work and some
    testing.
- -   Level D (qty. 3 units) parts need an undetermined amount of labor to debug,
    update and test.

A safe conservative estimate for salable units is 11.  With added labor, we
should be able to make 19.  With undetermined labor, 22 units total could be
salvaged.

A chart of the systems inventory is included herein.

MONITORS AND 3D BEZELS

There were 11 or 12 20" monitors with bezels.  There were also 41 17" monitors
with bezels.  These tallies were based on matched sets of the monitors and
bezels.  There were also several orphan bezels and monitors.

EYEWEAR

We found about 140 pairs of the preferred eyewear used to view the 3D monitors.
There were approximately 1200 of the low cost plastic glasses.

SYSTEM CARTS

There were no complete cart systems needed to install the systems found at the
site.

                               ASSET PURCHASE AGREEMENT


    ASSET PURCHASE AGREEMENT (the "Agreement") is dated as of July 26, 1996, by
and between Vista Medical Technologies, Inc., a California corporation (the
"Purchaser"), ProMedica Distribution, Inc., a California corporation (the
"Seller") and, solely for purposes of Sections 7.6 and 7.7 of this Agreement,
Ellen Palo and Judie Vivian, the shareholders of Seller (individually, a
"Shareholder" and collectively, the "Shareholders").

                                      RECITALS:

    A.   Seller is engaged in the distribution of certain cardiovascular
products.

    B.   Purchaser desires to purchase from Seller and Seller desires to sell
to Purchaser, on the terms and subject to the conditions of this Agreement,
certain of the assets of Seller as set forth hereunder.

    C.   Seller and Purchaser intend that the transactions contemplated hereby
be a "reorganization" as defined by Section 358(a)(1)(C) of the Internal Revenue
Code of 1986, as amended (the "Code").

    NOW, THEREFORE, in consideration of the representations, agreements herein
contained, the parties agree as follows:

1.  PURCHASE AND CONSIDERATION.

    1.1  PURCHASE AND SALE.  Subject to the terms and conditions of this
Agreement, Seller agrees to transfer, convey, assign and deliver to Purchaser on
the Closing Date (as hereinafter defined), and Purchaser agrees to buy from
Seller, free and clear of all encumbrances (except as permitted under this
Agreement), all the assets and properties, tangible and intangible, real,
personal or mixed, owned or leased by Seller, of and pertaining to or used by
Seller, wherever located, whether known or unknown, and whether or not on the
books and records of Seller (the "Assets"), including by way of example but not
of limitation the following:

         1.1.1     all of Seller's right, title and interest under (a) (i) that
certain Distribution Agreement between Seller and Peters, a French corporation,
dated November 10, 1992 and (ii) that certain U.S.A. Distribution Agreement
between Seller and Delacroix-Chevalier, Inc. dated September 1, 1991
(collectively, the "Distribution Agreements") and (b) (i) those certain sales
representative agreements pursuant to which the Inventory (as defined below) has
been sold in the past and (ii) that certain Sales Management Consultant
Agreement between Seller and Nancy More dated April 1, 1993 (collectively, the
"Sales Agreements");

<PAGE>

         1.1.2     all inventories, parts, supplies and products, and all of
Seller's rights to market, license and sell all products marketed, licensed or
sold by Seller under the Distribution Agreements, including, without limitation,
the Seller's rights as sole agent under the United States Food and Drug
Administration clearance to market such products in the United States (the
"Inventory");

         1.1.3     all of Seller's claims against any parties relating to items
included in the Assets, including, without limitation, unliquidated rights under
manufacturer's and vendors' warranties or guarantees, but only to the extent
such claims do not relate to any liabilities retained by Seller and not assumed
by Purchaser;

         1.1.4     all of Seller's transferable books and records, including,
without limitation, all customer and supplier lists, all advertising materials
and marketing plans, and manuals and other materials of Seller used in employee
and management training with respect to the Distribution Agreements or the Sales
Agreements; and

         1.1.5     accounts receivable in the amount of $84,017.

    1.2  ASSETS NOT TO BE TRANSFERRED.  Seller shall retain and Purchaser shall
not acquire any other assets or properties of Seller (the "Excluded Assets").

    1.3  NON-ASSIGNMENT OF CERTAIN ASSETS.  Notwithstanding anything to the
contrary in this Agreement, to the extent that the assignment hereunder of any
of the Assets requires the consent of any other party (or in the event that any
of the same shall be nonassignable), neither this Agreement nor any action taken
pursuant to its provisions shall constitute an assignment or an agreement to
assign if such assignment or attempted assignment would constitute a breach
thereof or result in the loss or diminution thereof; provided, however, that in
each such case, Seller shall use its best efforts to obtain the consent of such
other party to an assignment to Purchaser.  If such consent is not obtained by
the Closing Date, Seller shall cooperate with Purchaser in any arrangement
designed for Purchaser to perform Seller's obligations with respect to such
Asset after the Closing Date and for Purchaser to receive the benefits under any
such Asset after the Closing Date.

    1.4  ASSUMPTION OF LIABILITIES.  Subject to the terms and conditions
contained herein, on the Closing Date, Purchaser shall assume and agree
thereafter to pay, perform and discharge all liabilities and obligations of
Seller (a) under the Distribution Agreements and the Sales Agreements arising
from activities undertaken by Purchaser thereunder following the Closing and (b)
Seller's trade payables existing as of the date hereof in the maximum amount of
$84,017 (collectively, the "Assumed Liabilities").  Except for the Assumed
Liabilities, Purchaser shall not assume or have any responsibility for any other
liability, obligation or commitment of any nature, whether now or hereafter
existing, of Seller, and Seller shall pay all such liabilities, obligations or
commitments which are not Assumed Liabilities, including, without limitation,
liabilities or obligations arising out of inventory on Purchaser's books at
Closing or liabilities and obligations for payments to sales representatives
pursuant to the Sales Agreements or otherwise for sales made prior to

                                         -2-


<PAGE>

Closing.  Purchaser's assumption of such liabilities and obligations of Seller
is intended to inure solely to the benefit of Seller, and notwithstanding
anything herein to the contrary, such assumption is not intended and shall not
be construed to give any third parties any greater or additional benefits than
they would have but for Purchaser's said assumption.

    1.5  CONSIDERATION.  Purchaser shall pay the purchase price (the "Purchase
Price") to Seller as follows: (a) the issuance of Forty-Six Thousand (46,000)
shares of Purchaser's Series B Preferred Stock (the "Shares"); and (b) the
assumption of those obligations and liabilities of Sellers to be assumed by
Purchaser pursuant to Section 1.4 hereof.

    1.6  RESTRICTIONS ON RESALE.  The Shares will be subject to the following
restrictions against transfer by Seller and any persons receiving them upon
liquidation of Seller: (a) any restrictions imposed by applicable federal and
state securities laws; and (b) certificates representing the Shares will bear
legends describing the applicable restrictions on transferability referred to in
this Section 1.6, including the following legend:

    "The securities represented by this certificate are subject to the terms
    and conditions of an Asset Purchase Agreement, dated as of July 26, 1996,
    which includes certain restrictions on the sale of the securities.  Copies
    of the agreement may be obtained upon written request to the Secretary of
    Vista Medical Technologies, Inc.."

    1.7  INSTRUMENTS OF TRANSFER.  The sale, assignment, transfer, conveyance
and delivery of the Assets shall be made by such bills of sale and other
recordable instruments of assignment, transfer and conveyance as Purchaser shall
reasonably request.

    1.8  SALES TAXES.  Seller shall pay and promptly discharge when due the
entire amount of any and all sales and use tax ("Sales Tax") imposed or levied
by reason of the sale of the Assets to Purchaser.  The parties shall cooperate
with each other to the extent reasonably requested and legally permitted to
minimize any such Sales Tax.

2.  CLOSING.

    2.1  THE CLOSING.  The transactions contemplated by this Agreement shall be
consummated (the "Closing") at the offices of Brobeck, Phleger & Harrison LLP,
550 West C Street, Suite 1200, San Diego, California 92101, at 10:00 a.m., local
time, on July 26, 1996, or on such other date as the parties shall mutually
agree (the "Closing Date").

    2.2  ACTIONS AT THE CLOSING.  At the Closing (or at such later date as
Seller and Purchaser agree): (a) Purchaser shall provide to Seller (or Seller's
designees) a stock certificate(s) in the name of the Seller (or its designees)
representing the Shares; (b) Purchaser and Seller (or its designees) shall have
executed and delivered the Amended and Restated Investors' Rights Agreement (the
"Rights Agreement") substantially in the form of EXHIBIT A hereto; and (c)

discretion, shall be prepared and filed by Purchaser and taxes shown to be due

be used in connection with the distribution and/or marketing of cardiovascular
products, Seller's historic business activity.

    (b)  Representations and Covenants of Seller:

acquire substantially all of the assets of Seller.  Specifically, at least
ninety percent (90%) of the fair market value of the net assets and at least
seventy percent (70%) of the fair market value of the gross assets held by

following assets will be treated as property held by Seller immediately prior to
the Transactions: (a) assets disposed of by Seller prior to the Transactions and
in contemplation thereof (including, without limitation, any asset disposed of

intent existing during the period beginning with the commencement of

Period")); (b) assets used by Seller to pay expenses or liabilities incurred in
connection with the Transactions; and (c) assets used to make distribution,

least one significant historic business line and/or a significant portion of its
historic business assets to Purchaser.

         (iv)      Seller's principal reasons for participating in the
Transactions are BONA FIDE business purposes not related to taxes.

         (v)       Seller has no Knowledge of, and believes that there does not
exist, any plan or intention on the part of shareholders (or any shareholder) of
Seller to engage in a sale, exchange, transfer, distribution, pledge (other than
pledges in connection with BONA FIDE loan transactions), disposition or any
other transaction which would result in a reduction in the risk of ownership or
a direct or indirect disposition (a "Sale") of Shares to be received in the plan
of liquidation pursuant to the Transactions that would reduce the ownership of
all Seller shareholders of such Shares to a number of shares having an aggregate
fair market value, as of the closing of the Transactions, of less than fifty
percent (50%) of the aggregate fair market value, of Seller stock outstanding
immediately prior to the consummation of the Transactions.

         (vi)      Seller intends that no consideration be paid or received
(directly or indirectly, actually or constructively) for the Assets being
transferred to Purchaser other than shares of Purchaser voting stock.

         (vii)     Seller will pay separately its own expenses relating to the
Transactions.

         (viii)    Seller has adopted a plan of complete liquidation pursuant
to which Seller will liquidate and distribute the Shares received in the
Transactions to the Shareholders as soon as reasonably possible after the
Transactions and in no event later than twelve (12) months after the
Transactions.

    (c)  Representations and Covenants of the Shareholders:

         (i)       Each Shareholder does not have any plan or intention to
engage in a sale, exchange, transfer, distribution, pledge (other than pledges
in connection with BONA FIDE loan transactions), disposition or any other
transaction which would result in a reduction in the risk of ownership or a
direct or indirect disposition of the Shares to be received in the plan of
liquidation pursuant to the Transactions that would reduce such Shareholder's
ownership of such Shares to a number of shares having an aggregate fair market
value, as of the closing of the Transactions, of less than seventy percent (70%)
of the aggregate fair market value of Seller stock owned by the such Shareholder
immediately prior to the consummation of the Transactions and each Shareholder
has no knowledge of, and believes that there does not exist, any plan or
intention on the part of shareholders (or any shareholder) of Seller to engage
in a sale, exchange, transfer, distribution, pledge (other than pledges in
connection

                                         -10-

with BONA FIDE loan transactions), disposition or any other transaction which
would result in a reduction in the risk of ownership or a direct or indirect
disposition (a "Sale") of Shares to be received in the plan of liquidation
pursuant to the Transactions that would reduce the ownership of all Shareholders
of such stock to a number of shares having an aggregate fair market value, as of
the closing of the Transactions, of less than fifty percent (50%) of the
aggregate fair market value, of Seller stock outstanding immediately prior to
the consummation of the Transactions.

    7.7  COLLECTION OF ACCOUNTS RECEIVABLE.  Each of the shareholders, jointly
and severally, hereby guarantees that the accounts receivable included in the
Assetes transferred hereunder shall be collected and paid to Purchaser within
sixty (60) days of Closing.

8.  INDEMNIFICATION.

    8.1  INDEMNIFICATION.

         8.1.1     Seller agrees to indemnify and hold Purchaser and its
affiliates harmless against all claims, losses, liabilities, damages,
deficiencies, costs and expenses, including reasonable attorneys' fees and
expenses of investigation (hereafter individually a "Loss" and collectively
"Losses") incurred by Purchaser or any of its affiliates (a) as a result of any
inaccuracy of a representation or breach of any warranty contained herein or in
any schedule, exhibit or other document delivered pursuant hereto by Seller or
any failure by Seller to perform or comply with any covenant contained herein or
in any schedule, exhibit or other document delivered pursuant hereto, or
resulting from or relating to any claim or action by any third party questioning
the validity of or otherwise seeking to rescind the transfer hereunder by Seller
to Purchaser of all right, title and interest in and to the Assets, (b) relating
to or resulting from any liabilities, obligations or commitments of, and all
claims against, Seller, or against or involving any of the Assets, arising from
or based upon any condition, event or action existing on or occurring before the
Closing Date, except to the extent specifically assumed by Purchaser as an
Assumed Liability, and (c) the failure of the parties hereto to comply with (i)
the "bulk sales" or "bulk transfer" laws or (ii) sales and use laws of any
jurisdiction in connection with the transactions contemplated hereby.

         8.1.2     Purchaser agrees to indemnify and hold Seller harmless
against all Losses incurred by Seller as a result of any inaccuracy of a
representation or breach of any warranty, or any failure by Purchaser to perform
or comply with any covenant, contained herein or in any other document delivered
pursuant hereto or resulting from or relating to third party claims based on
Purchaser's use or operation of the Assets following the Closing Date.

         8.1.3     Each party agrees to give the other written notice of any
event or assertion of which it has knowledge concerning any liability as to
which it may request indemnification hereunder.  Each party will cooperate with
the other in determining the validity of any such claim or assertion.  In each
case, the indemnifying party shall have the right to defend any such third-party
suits, claims or proceedings with counsel satisfactory to

                                         -11-


<PAGE>

the indemnified party.  Each party agrees not to settle or compromise any such
third-party suit, claim or proceeding without the prior written consent of the
other, which consent shall not be unreasonably withheld.  Upon obtaining
knowledge of the institution of any action, proceeding or other event which
could give rise to a claim of indemnity pursuant to this Section 8, the party
seeking indemnification shall promptly give written notice to the other party(s)
hereof.  If such claim or demand relates to a claim or demand asserted by a
third party, the indemnifying party shall have the right at its expense to
employ counsel to defend such claim or demand and the indemnified party shall
have the right, but not the obligation, to participate in the defense of any
such claim or demand.  So long as the indemnifying party is defending such claim
or demand in good faith, the indemnified party will not settle such claim or
demand without the indemnifying party's consent, which consent shall not be
unreasonably withheld.  The indemnified party shall make available to the
indemnifying party all records and other materials reasonably required by it in
contesting a claim or demand asserted by a third party against the indemnified
party and shall cooperate in the defense thereof.

         8.1.4     The indemnification obligations of the respective parties
under this Section 8 shall terminate on the first anniversary of the Closing
Date, but shall not terminate as to any Loss (or a potential claim by an
appropriate party) asserted in good faith prior to such date; PROVIDED, HOWEVER,
any claim for indemnification with respect to any Tax related matter shall
terminate upon the expiration of all applicable statutes of limitation.

    8.2  NON-EXCLUSIVITY OF REMEDY.  The indemnification provisions contained
in this Section 8 shall not be deemed to be the exclusive remedy or exclusive
means to obtain relief, as the case may be, of any party hereto, and the
provisions of this Section 8 shall not prejudice any other rights or remedies
that may be available to any party at law, in equity or otherwise.

    8.3  SURVIVAL.  Representations and warranties made hereunder in Sections 3
and 4 shall terminate on the first anniversary of the Closing Date, PROVIDED,
that in the event a claim for indemnification pursuant to Section 8 hereof, or
any other claim is asserted, based on a claim of misrepresentation or breach of
warranty set forth in Sections 3 or 4 hereof prior to the first anniversary date
of the Closing Date, such representations and warranties shall survive until the
resolution of such claim.

9.  MISCELLANEOUS PROVISIONS.

    9.1  ASSIGNMENT, SUCCESSORS AND ASSIGNS.  This Agreement shall be binding
upon and shall inure to the benefit of the parties hereto and their respective
successors and assigns.  Purchaser may assign its rights and obligations under
this agreement to any party without the consent of Seller, provided that the
assignee assumes Purchaser's liabilities and obligations under this Agreement.
Except as set forth in this Agreement, Seller may not assign its rights and
obligations hereunder.

                   AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT


    THIS AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT (the "AGREEMENT") is
made as of the 12th day of July, 1996, by and between Vista Medical
Technologies, Inc., a California corporation (the "Company"), and the
Shareholders listed on Schedule A hereto, each of which is herein referred to as
a "Shareholder."

                                       RECITALS

    WHEREAS, the Company and certain of the Shareholders (the "SERIES A
SHAREHOLDERS") are parties to a certain Investors Rights Agreement dated as of
July 27, 1995, as amended on September 15, 1995 (the "PRIOR AGREEMENT"),
pursuant to which the Company has agreed to the extent possible to grant to the
Series A Shareholders certain rights to cause the Company to register shares of
Common Stock issuable to the Series A Shareholders upon conversion of the
Company's Series A-1 Preferred Stock and Series A-3 Preferred Stock (the "SERIES
A PREFERRED") in the event the Company grants such rights to other shareholders,
and certain other matters as set forth therein;

    WHEREAS, the Company and certain of the Shareholders (the "SERIES B
SHAREHOLDERS") are parties to the Series B Preferred Stock Purchase Agreement of
even date herewith (the "SERIES B AGREEMENT"); and

    WHEREAS, in order to induce the Company to enter into the Series B
Agreement and to induce the Series B Shareholders to purchase shares of the
Company's Series B Preferred Stock (the "SERIES B PREFERRED") pursuant to the
Series B Agreement, the Shareholders and the Company hereby agree that this
Agreement shall amend and restate the Prior Agreement so that this Agreement
shall govern the obligations of the Company to register the resale of shares of
Common Stock issuable to the Shareholders upon conversion of their shares of the
Company's Series A Preferred and/or Series B Preferred, and certain other
matters as set forth herein.

    NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

                                      SECTION 1.

         RESTRICTIONS ON TRANSFER; REGISTRATION RIGHTS

    1.1  RESTRICTIONS ON TRANSFERABILITY.  Neither the Series A Preferred or
the Series B Preferred nor the Registrable Securities (as defined below) shall
be transferable except upon the conditions specified in this Agreement, which
conditions are intended to insure compliance with the provisions of the
Securities Act (as defined below), or upon such other terms as are in the
opinion of counsel to the Company satisfactory to comply with the

                                         -1-


<PAGE>

provisions of the Securities Act.  Except for transfers made pursuant to Rule
144 of the Securities Act, the Shareholders will cause any proposed transferee
of Series A Preferred, Series B Preferred or Registrable Securities held by any
Shareholder to agree to take and hold such securities subject to the provisions
and upon the conditions specified in this Agreement and it will be a condition
precedent to the effectiveness of any such transfer that the Company shall have
secured a written agreement in form and substance satisfactory to the Company to
that effect, if so requested by the Company,

    1.2  CERTAIN DEFINITIONS.  As used in this Agreement, the following terms
shall have the following respective meanings:

    "COMMISSION" shall mean the Securities and Exchange Commission or any other
federal agency at the time administering the Securities Act.

    "FORM S-3" shall mean Form S-3 under the Securities Act (as defined below)
as in effect on the date of this Agreement, or any substantially similar,
equivalent or successor form under the Securities Act.

    "HOLDER" shall mean each holder of Registrable Securities.

    "REGISTRABLE SECURITIES" means (i) the Common Stock issuable or issued upon
conversion of the Series A Preferred, (ii) the Common Stock issuable or issued
upon conversion of the Series B Preferred and (iii) any Common Stock of the
Company issued as (or issuable upon the conversion or exercise of any warrant,
right or other security which is issued as) a dividend or other distribution
with respect to, or in exchange for or in replacement of, the shares referenced
in (i) and (ii) above, excluding in all cases, however, any Registrable
Securities sold by a person in a transaction in which his rights under this
Section 1 are not assigned.

    The terms "REGISTER," "REGISTERED" and "REGISTRATION" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act, and the declaration or ordering of the
effectiveness of such registration statement.

    "REGISTRATION EXPENSES" shall mean all expenses incurred by the Company in
complying with Sections 1.5, 1.6 and 1.7 hereof other than Selling Expenses,
including, without limitation, all registration, qualification and filing fees,
printing expenses, escrow fees, fees and disbursements of Company counsel, blue
sky fees and expenses, and the expense of any special audits incident to or
required by any such registration (but excluding the compensation of regular
employees of the Company which shall be paid in any event by the Company).

    "RESTRICTED SECURITIES" shall mean the securities of the Company required
to bear the legend set forth in Section 1.3 hereof or a legend substantially
similar thereto and all shares of Common Stock outstanding on the date of this
Agreement.

                                         -2-


<PAGE>

    "SECURITIES ACT" shall mean the Securities Act of 1933, as amended, or any
similar federal statute and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time.

    "SELLING EXPENSES" shall mean all underwriting discounts and selling
commissions applicable to the applicable sale.

    1.3  RESTRICTIVE LEGEND(S).

    (a)  Each certificate representing the shares of Series A Preferred, Series
B Preferred and Registrable Securities shall (unless otherwise permitted by the
provisions of Section 1.4 below) be stamped or otherwise imprinted with a legend
in the following form (in addition to any legend required under applicable
California or other state securities laws):

    THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
    INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
    AS AMENDED.  SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
    SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT.  COPIES OF THE
    AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
    TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
    OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION.

    (b)  Each certificate representing shares of Registrable Securities into
which shares of the Series A Preferred and/or Series B Preferred are converted
also shall be stamped or otherwise imprinted with any legend required by the
Bylaws of the Company (in addition to any legend required under applicable
California or other state securities laws).

    1.4  NOTICE OF PROPOSED TRANSFERS.  The holder of each certificate
representing the Restricted Securities, by acceptance thereof, agrees to comply
in all respects with the provisions of this Section 1.4. Prior to any proposed
transfer of any Restricted Securities, unless there is in effect a registration
statement under the Securities Act covering the proposed transfer, the holder
thereof shall give written notice to the Company of such holder's intention to
effect such transfer.  Each such notice shall describe the manner and
circumstances of the proposed transfer in sufficient detail, and shall be
accompanied (except in transactions in compliance with Rule 144) by either (i) a
written opinion of legal counsel which shall be reasonably satisfactory to the
Company addressed to the Company and reasonably satisfactory in form and
substance to the Company's counsel, to the effect that the proposed transfer of
the Restricted Securities may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission, a copy of any
holder's request (together with all supplements or amendments thereto) to which
shall have been provided to the Company, at or prior to the time of first
delivery to the Commission's staff, to the effect that the transfer of such
securities without registration will not result in a recommendation by such
staff that action be taken with respect thereto, whereupon the

                                         -3-


<PAGE>

holder of such Restricted Securities shall be entitled to transfer such
Restricted Securities in accordance with the terms of the notice delivered by
the holder to the Company.  Each certificate evidencing the Restricted
Securities transferred as provided for above shall bear the appropriate
restrictive legend set forth in Section 1.3 above, except that such certificate
shall not bear such restrictive legend if, in the opinion of counsel for the
Company or counsel for such holder, such legend is not required in order to
establish compliance with any provisions of the Securities Act.

    Notwithstanding the provisions above, no such opinion of counsel or "no
action letter" shall be necessary for a transfer by a Shareholder which is a
partnership to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such
partner or retired partner ("PARTNERS"), if the transferee agrees in writing to
be subject to the terms hereof to the same extent as if he were an original
Shareholder hereunder.

    1.5  DEMAND REGISTRATION RIGHTS.

    (a)  Commencing on July 12, 1999, if the Company shall receive a written
request (specifying that it is being made pursuant to this Section 1.5) from the
Holders of at least forty percent (40%) of the Registrable Securities that the
Company file a registration statement or similar document under the Securities
Act covering the registration of Registrable Securities the expected aggregate
offering price to the public of which is at least $7,500,000, then the Company
shall promptly notify all other Holders of such request and shall use its best
efforts to cause all Registrable Securities that such Holders have requested,
within fifteen (15) days after receipt of such written notice, to be registered
in accordance with this Section 1.5 to be registered under the Securities Act.
The Holders making the written request pursuant to this Section 1.5 shall be
referred to hereinafter as the "INITIATING HOLDERS".

    Notwithstanding the foregoing, (i) the Company shall not be obligated to
effect a registration pursuant to this Section 1.5 during the period starting
with the date one hundred twenty (120) days prior to the Company's estimated
date of filing of, and ending on a date one hundred eighty (180) days following
the effective date of, a registration statement pertaining to an underwritten
public offering of the Company's securities, provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective and that the Company's estimate of
the date of filing such registration statement is made in good faith; and (ii)
if the Company shall furnish to such Holders a certificate signed by the
President of the Company stating that in the good faith judgment of the Board of
Directors it would be seriously detrimental to the Company or its shareholders
for a registration statement to be filed in the near future, then the Company's
obligation to use its best efforts to file a registration statement shall be
deferred for a period not to exceed six (6) months; provided, however, that the
Company shall not obtain such a deferral more than once in any 12-month period.

                                         -4-

    The Company shall be obligated to effect not more than two (2)
registrations pursuant to this Section 1.5 for which holders of Registrable
Securities are the Initiating Holders.

    (b)  If the Initiating Holders intend to distribute the Registrable
Securities covered by their demand by means of an underwriting, they shall so
advise the Company as part of their demand made pursuant to this Section 1.5,
and the Company shall include such information in the notice referred to in
Section 1.5(a). In such event, the right of any Holder to registration pursuant
to this Section 1.5 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder) to the extent provided herein.

    The Company shall, together with all Holders proposing to distribute their
securities through such underwriting, enter into an underwriting agreement in
customary form with the underwriter or underwriters selected by the Company and
reasonably satisfactory to a majority of interest of the Initiating Holders.
Notwithstanding any other provision of this Section 1.5, if the underwriter
shall advise the Company in writing that marketing factors (including, without
limitation, an adverse effect on the per share offering price) require a
limitation of the number of shares to be underwritten, then the Company shall so
advise all Holders of Registrable Securities that would otherwise be registered
and underwritten pursuant hereto, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated pro rata among such Holders thereof in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement.  No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.

    If any Holder disapproves of the terms of the underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company, the underwriter
and the Initiating Holders.  The Registrable Securities so withdrawn shall also
be withdrawn from registration.  If by the withdrawal of such Registrable
Securities a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the maximum of any limitation imposed by
the underwriters), then the Company shall offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used in determining the
underwriter limitation in this Section 1.5.

    If the underwriter has not limited the number of Registrable Securities to
be underwritten, the Company may include securities for its own account (or for
the account of other securityholders) in such registration if the underwriter so
agrees and if the number of Registrable Securities that would otherwise have
been included in such registration and underwriting will not thereby be limited.

    1.6  COMPANY REGISTRATION.

                                         -5-


<PAGE>

    (a)  If, at any time or from time to time, the Company shall determine to
register any of its securities, either for its own account or the account of a
securityholder or holders exercising their respective demand registration
rights, other than a registration relating solely to employee benefit plans on
Form S-8 or similar forms which may be promulgated in the future or a
registration on Form S-4 or similar forms which may be promulgated in the future
relating solely to a Securities and Exchange Commission Rule 145 or similar
transaction the Company will (i) promptly give to each Holder written notice
thereof and (ii) include in such registration (and any related qualification
under Blue Sky laws or other compliance), and in any underwriting involved
therein, all Registrable Securities of such Holders as specified in a written
request or requests made within fifteen (15) days after receipt of such written
notice from the Company.

    (b)  If the registration of which the Company gives notice is for a
registered public offering involving an underwriting, the Company shall so
indicate in the notice given pursuant to Section 1.6(a). In such event the right
of any Holder to registration pursuant to this Section 1.6 shall be conditioned
upon such Holder's agreeing to participate in such underwriting and to the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.  All Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other Holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company or by other holders exercising any
demand registration rights.  Notwithstanding any other provision of this Section
1.6, if the underwriter determines that marketing factors require a limitation
of the number of shares to be underwritten, the underwriter may exclude some or
all Registrable Securities or other securities from such registration and
underwriting (hereinafter an "UNDERWRITER CUTBACK"); provided, however, that if
such underwriting relates to any registration statement other than a
registration statement being filed with respect to the first registration
statement filed by the Company covering an underwritten offering of any of its
securities to the general public ("INITIAL PUBLIC OFFERING") in which no
secondary shares are included, then (i) in no event shall the aggregate number
of shares of Registrable Securities included in such underwriting be reduced
below thirty (30%) of the total number of shares proposed to be included in such
underwriting.  In the event of an Underwriter Cutback, the Company shall so
advise all Holders and the other holders distributing their securities through
such underwriting, and the number of Registrable Securities and other securities
that may be included in the registration and underwriting shall be allocated
among all holders thereof (other than those holders who are exercising their
demand registration rights) on the basis that the holders who are not Holders
shall be cut back before any cutback of Holders.  If the limitation determined
by the underwriter requires an Underwriter Cutback, such Underwriter Cutback
shall be in proportion, as nearly as practicable, to the respective amounts of
Registrable Securities held by such Holders at the time of filing the
registration statement.  If any Holder disapproves of the terms of any such
underwriting, such Holder may elect to withdraw therefrom by written notice to
the Company and the underwriter.  Any securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.

                                         -6-


<PAGE>

    1.7  FORM S-3 REGISTRATION RIGHTS.  After the Initial Public Offering, the
Company shall use its best efforts to qualify for registration on Form S-3, and
to that end the Company shall use its best efforts to comply with the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), within twelve (12) months following the effective date of the first
registration of any securities of the Company for an underwritten registered
public offering.  After the Company has qualified for the use of Form S-3, and
subject to the provisions of Section 1. 14, each Holder shall have the right to
request registrations on Form S-3 (such requests shall be in writing and shall
state the number of shares of Registrable Securities to be disposed of and the
intended method of disposition of such shares by each such Holder), subject only
to the following limitations:

    (a)  The Company shall not be obligated to cause a registration on Form S-3
to become effective prior to one hundred eighty (180) days following the
effective date of a Company initiated registration (other than a registration
effected solely to qualify an employee benefit plan or to effect a business
combination pursuant to Rule 145);

    (b)  The Company shall not be required to effect a registration pursuant to
this Section 1.7 unless the Holder or Holders requesting such a registration
propose to dispose of shares of Registrable Securities having an aggregate
disposition price (before deduction of underwriting discounts and expenses of
sale) of at least $500,000;

    (c)  The Company shall not be required to effect a registration pursuant to
this Section 1.7 if the Company shall furnish to the requesting Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company or its shareholders for the registration statement to
be filed at the date filing would be required, in which case the Company shall
have an additional period of not more than one hundred twenty (120) days within
which to file such registration statement; provided however, that the Company
shall not use this right more than once in any 12-month period;

    (d)  The Company shall not be required to maintain and keep any such
registration on Form S-3 effective for a period exceeding one hundred twenty
(120) days from the effective date thereof;

    (e)  The Company shall not be obligated to cause a registration on Form S-3
if in the prior six-month period the Company has caused a registration on Form
S-3 to become effective; and

    (f)  The Company shall be obligated to effect not more than two
registrations per year pursuant to this Section 1.7 for which holders of
Registrable Securities request such registration.

    The Company shall give notice to all Holders of the receipt of a request
for registration pursuant to this Section 1.7 and shall use its best efforts to
cause all Registrable Securities that such Holders have requested, within
fifteen (15) days after receipt of such

                                         -7-


<PAGE>

written notice, be registered in accordance with this Section 1.7 to be
registered under the Securities Act.  Subject to the foregoing, the Company will
use its best efforts to effect promptly any registration pursuant to this
Section 1.7. The provisions of Section 1.5(b) shall apply to any registration
effected pursuant to this Section 1.7

    1.8  EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Sections 1.5, 1.6 and 1.7 (exclusive of Selling Expenses but inclusive of the
reasonable fees and expenses of one special counsel to the selling Holders)
shall be borne by the Company.  Notwithstanding anything to the contrary herein,
the Company shall not be required to pay for any expenses of any registration
proceeding under Section 1.5 if the registration request is subsequently
withdrawn at the request of the Holders of a majority of the Registrable
Securities to have been registered, unless such Holders agree to forfeit their
right to a demand registration pursuant to Section 1.5 (in which event such
right shall be forfeited by all Holders).  In the absence of such an agreement
to forfeit, the Holders of Registrable Securities to have been registered shall
bear all such expenses pro rata on the basis of the Registrable Securities to
have been registered.  Notwithstanding the foregoing, however, if at the time of
the withdrawal, the Holders have learned of a material adverse change in the
condition, business or prospects of the Company from that known to the Holders
at the time of their request, of which the Company had knowledge at the time of
the request, then the Holders shall not be required to pay any of said expenses
and shall retain their rights pursuant to Section 1.5.

    1.9  REGISTRATION PROCEDURES.  In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder 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:

    (a)  Keep such registration, qualification or compliance effective for a
period of one hundred twenty (120) days or until the Holder or Holders have
completed the distribution described in the registration statement relating
thereto, whichever first occurs;

    (b)  Prepare and file with the Commission 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;

    (c)  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 they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them;

    (d)  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 shall be reasonably requested by the Holders, provided that the
Company shall not be

                                         -8-


<PAGE>

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;

    (e)  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 Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement; and

    (f)  Notify each Holder of Registrable Securities covered by 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.

    Notwithstanding any provision to the contrary in this Agreement, the
Company shall not be required in connection with any registration pursuant to
Sections 1.5, 1.6 or 1.7 to qualify shares in any state or jurisdiction which
requires the Company to qualify to do business or to file a general consent to
service of process.

    1.10 INDEMNIFICATION.

    (a)  The Company will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Section 1, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, 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, in
light of the circumstances in which they were made, not misleading, or any
violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will promptly reimburse each such Holder, each of its
officers and directors and partners, and each person controlling such Holder,
each such underwriter and each person who controls any such underwriter, for any
legal and any other expenses reasonably incurred (as and when incurred) in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written

                                         -9-


<PAGE>

information furnished to the Company by an instrument duly executed by such
Holder or underwriter and stated to be specifically for use therein.

    (b)  Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify 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 or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and directors and partners and each
person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof) including any of the foregoing incurred in
settlement of any litigation commenced or threatened, arising out of or based on
any untrue statement (or alleged untrue statement) of a material fact contained
in any such registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, 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, in the light of the circumstances in
which they were made, not misleading, or any violation by the Company of any
rule or regulation promulgated under the Securities Act applicable to the
Company in connection with any such registration, qualification, or compliance,
and will promptly reimburse the Company, such Holders, such directors,
officer's, partners, persons, underwriters or control persons for any legal or
any other expenses reasonably incurred (as and when incurred) in connection with
investigation, preparing or defending 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 or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by an instrument
duty executed by such Holder and stated to be specifically for use therein,
provided, however, that the obligations of each such Holder hereunder shall be
limited to an amount equal to the proceeds to each such Holder of Registrable
Securities sold as contemplated herein.

    (c)  Each party entitled to indemnification under this Section 1.10 (the
"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, and shall
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
withheld), and the Indemnified Party may participate in such defense at its own
expense, and provided further that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 1 unless such failure resulted in actual
detriment to the Indemnifying Party.  No Indemnifying Party, in the defense of
any such claim or litigation, shall, except with the consent of each Indemnified
Party, consent to entry of any judgment or enter into any settlement which does
not include

                                         -10-


<PAGE>

as an unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party a release from all liability in respect of such claim or
litigation.

    (d)  If the indemnification provided for in this Section 1.10 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations.  The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Indemnifying Party or by the Indemnified
Party and the parties relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

    (e)  The obligations of the Company and Holders under this Section 1.10
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1 and otherwise.

    1.11 INFORMATION BY HOLDER.  The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Section 1.

    1.12 RULE 144 REPORTING.  With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to:

    (a)  Use its best efforts to make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act at
all times after the effective date of the first registration under the
Securities Act filed by the Company for an offering of its securities to the
general public;

    (b)  Use its best efforts to then file with the Commission in a timely
manner all reports and other documents required of the Company under the
Exchange Act at any time after it has become subject to such reporting
requirements,

    (c)  So long as a Shareholder owns any Restricted Securities, to furnish to
the Shareholder forthwith upon 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

                                         -11-


<PAGE>

effective date of the first registration statement filed by the Company for an
offering of its securities to the general 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 report of the Company, and such
other reports and documents of the Company as a Shareholder may reasonably
request in availing itself of any rule or regulation of the Commission allowing
a Shareholder to sell any such securities without registration.

    1.13 TRANSFER OF REGISTRATION RIGHTS.  The rights to cause the Company to
register securities granted under Sections 1.5, 1.6 and 1.7 may be assigned or
otherwise conveyed to a transferee or assignee of Registrable Securities, who
shall be considered a "Holder," and the transferred shares shall be considered
"Registrable Securities," for purposes of this Section 1, provided that (i) said
transferee acquires (or, together with affiliates (as defined under the
Securities Act) ("AFFILIATES") of said transferee, after the acquisition then
beneficially owns) at least 250,000 shares of the Registrable Securities
(including shares of Series A Preferred and Series B Preferred prior to
conversion into Registrable Securities) and (ii) the Company is given written
notice by such Holder at the time of or within a reasonable time (but not more
than thirty (30) days) after said transfer, stating the name and address of said
transferee or assignee and identifying the securities with respect to which such
registration rights are being assigned, subject to said transferee's agreement
to be bound by and comply with the provisions of this Section 1.

    1.14 TERMINATION OF REGISTRATION RIGHTS.  The registration rights granted
pursuant to this Section 1 shall terminate (i) upon the seventh anniversary of
the effective date of the first registration statement filed by the Company
covering the Initial Public Offering or (ii) if earlier, as to any individual
Holder, at such time after the Company's Initial Public Offering as all
Registrable Securities (including shares of Series A Preferred and Series B
Preferred prior to conversion into Registrable Securities) held by such Holder
can be sold within any three-month period without compliance with the
registration requirements of the Securities Act pursuant to Rule 144 (including
Rule 144(k)) promulgated thereunder.

    1.15 "MARKET STAND OFF" AGREEMENT.  Each Holder hereby agrees that, during
the period of duration specified by the Company and an underwriter of common
stock or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Act, it shall not, to the
extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it at any time during such period except common stock included in such
registration; PROVIDED, HOWEVER, that:

              (a)  such agreement shall not exceed 180 days for the first such
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

                                         -12-


<PAGE>

              (b)  such agreement shall not exceed 90 days for any subsequent
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;
and

              (c)  all executive officers and directors of the Company and all
other persons with registration rights under this Agreement enter into similar
agreements.

              In order to enforce the foregoing covenant, the Company may
impose stop-transfer instructions with respect to the Registrable Securities of
each Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.  Notwithstanding the
foregoing, the obligations described in this Section 1.15 shall not apply to a
registration relating solely to employee benefit plans on Form S-8 or similar
forms which may be promulgated in the future, or a registration relating solely
to a SEC Rule 145 transaction on Form S-14 or Form S-15 or similar forms which
may be promulgated in the future.

                                      SECTION 2.

                AFFIRMATIVE COVENANTS OF THE COMPANY AND SHAREHOLDERS

    2.1  FINANCIAL INFORMATION.  Subject to Section 2.3, the Company will
furnish the following reports to the Shareholders for so long as the

and setting forth in each case in comparative form the figures for the previous
fiscal year, all in reasonable detail and certified by independent public
accountants of recognized national standing selected by the Company;

    (b)  Each month, an unaudited consolidated balance sheet of the Company and
its subsidiaries, if any, and consolidated statements of income and consolidated

    (c)  An annual operating budget for each coming year, delivered on or
before January 1 of each year; and

    (d)  Such other information relating to the financial condition, business,
prospects or corporate affairs of the Company as the investor may from time to
time request, provided,

                                         -13-


<PAGE>

however, that the Company shall not be obligated to provide information which it
deems proprietary.

    2.2  ASSIGNMENT OF RIGHTS TO FINANCIAL INFORMATION.  The rights granted
pursuant to Section 2.1 may be assigned by the Shareholders (or by any permitted
transferee of any such rights) so long as (i) the Company is given notice of any
such assignment within a reasonable time after the date the same is effected,
(ii) the transferee shall have acquired (or, together with such transferee's
Affiliates, after the acquisition shall then beneficially own) at least 250,000
shares of Registrable Securities (including shares Series A Preferred and Series
B Preferred prior to conversion into Registrable Securities) in a private
transaction and (iii) the transferee is not engaged in a business that is
competitive with the Company.

    2.3  INSPECTION RIGHTS.

    (a)  The Company will permit any Investor, so long as such Investor (or its
representative) owns at least 200,000 Shares, or such number of shares of Common
Stock issued upon conversion of 200,000 or more Shares, or any combination
thereof (as presently constituted and subject to subsequent adjustment for stock
splits, stock dividends, reverse stock splits, recapitalizations and the like)
(a "SIGNIFICANT HOLDER") (or a representative of any Significant Holder) to
visit and inspect any of the properties of the Company, including its books of
account and other records (and make copies thereof and take extracts therefrom),
and to discuss its affairs, finances and accounts with the Company's officers
and its independent public accountants, all at such reasonable times and as
often as any such person may reasonably request.

    (b)  The provisions of Section 2.2 and this Section 2.3 shall not be in
limitation of any rights which any Holder or Significant Holder may have with
respect to the books and records of the Company and its subsidiaries, or to
inspect their properties or discuss their affairs, finances and accounts, under
the laws of the jurisdictions in which they are incorporated.

    2.4  ATTENDANCE AT BOARD MEETINGS.  So long as Kaiser Aerospace &
Electronics ("Kaiser") owns at least an aggregate of 1,000,000 shares of Series
A Preferred, and so long as Kaiser does not have a representative on the Board
of Directors of the Company, Kaiser shall receive from the Company notices of
all meetings of the Board of Directors, including without limitation telephonic
meetings, and Kaiser shall receive, with such limitations provided herein, any
materials distributed for such meeting, and may send one representative to such
meetings, PROVIDED, HOWEVER, that the Company may require as a condition
precedent that such representative proposing to attend any meeting of the Board
of Directors shall agree to hold in confidence and trust and to act in a
fiduciary manner with respect to all information so received during such
meetings and may require that such representative sign a confidentiality
agreement with the Company; and, PROVIDED, FURTHER, that the Company reserves
the right not to provide information and to exclude such representative from any
meeting or portion thereof if attendance at such meeting by such representative
or dissemination of any information at such meeting to such representative
would, in the good

faith judgment of the Board of Directors, result in disclosure of trade secrets
to such representative, would compromise or adversely affect the attorney-client
privilege between the Company and its counsel, or would, in the good faith
judgment of the Board of Directors, result in a conflict of interest situation.
If such representative in his or her good faith judgment believes that an item
to be discussed by the Board of Directors would result in any conflict of
interest, such representative shall promptly bring such conflict to the
attention of the Chairman of the Board.  In no event shall any provision of this
paragraph waive any obligation of confidentiality to the Company owed by any
such representative or Kaiser.

    2.5  TERMINATION OF COVENANTS.  The covenants set forth in Section 2.1,
Section 2.3 and Section 2.4 shall terminate and be of no further force or effect
after the closing date of the Initial Public Offering.

    2.6  CONFIDENTIAL INFORMATION, ETC.  Each Shareholder agrees that all
information received by it pursuant to this Section 2, and any other information
relating to the Company's technology, processes or formulas that is disclosed by
the Company to any Shareholder in writing and is marked "Confidential," shall be
considered confidential information.  Each Shareholder further agrees that it
shall hold all such confidential information in confidence and shall not
disclose any such confidential information to any third party other than its
counsel or accountants nor shall such Shareholder use such confidential
information for any purpose other than evaluation of such Shareholder's
investment in the Company; provided, however, that the foregoing obligation to
hold in confidence and not to disclose confidential information shall not apply
to any such information that (a) was known to the public prior to disclosure by
the Company, (b) becomes known to the public through no fault of such
Shareholder, (c) is disclosed to such Shareholder on a non-confidential basis by
a third party having a legal right to make such disclosure or (d) is
independently developed by such Shareholder.

                                      SECTION 3.

                               RIGHTS OF FIRST REFUSAL

    3.1  RIGHT OF FIRST REFUSAL ON COMPANY ISSUANCES.

    (a)  The Company hereby grants to each Shareholder the right of first
refusal to purchase its Pro Rata Share (defined below) of all (or any part) of
New Securities (defined below) that the Company may from time to time propose to
sell and issue.  Such Shareholder's "PRO RATA SHARE," for purposes of this
Section 3, is the ratio of the number of shares of Common Stock (assuming
conversion of all shares of Series A Preferred and Series B Preferred) then held
by such Shareholder to the total number of shares of Common Stock then
outstanding (assuming conversion of all shares of Series A Preferred and Series
B Preferred).  This right of first refusal shall be subject to the following
provisions:

    (b)  "NEW SECURITIES" shall mean any Common Stock or Preferred Stock of the
Company, whether now authorized or not, and rights, options, or warrants to
purchase said

                                         -15-


<PAGE>

Common Stock or Preferred Stock, and securities of any type whatsoever that are,
or may become, convertible into or exchangeable for said Common Stock or
Preferred Stock; provided, however, that "NEW SECURITIES" does not include (i)
securities issuable upon conversion of or with respect to Series A Preferred
Stock, Series B Preferred Stock or any future series of preferred stock; (ii)
shares of the Company's Common Stock (or related options) issued to officers,
directors, employees of and/or consultants to the Company pursuant to plans or
agreements as approved by the Company's Board of Directors; (iii) shares of the
Company's Common Stock or Preferred Stock issued in connection with any stock
split, stock dividend, or recapitalization by the Company; (iv) securities
issued in connection with any equipment leasing, technology licensing, corporate
partnering, strategic alliance, acquisition, merger, purchase of assets or
similar transaction as approved by the Company's Board of Directors; and (v)
shares of the Company's Common Stock issued or issuable as a result of any
antidilution adjustment provided for in the Company's Articles of Incorporation
as in effect at the time of such issuance.

    (c)  In the event that the Company proposes to undertake an issuance of New
Securities, it shall give each Shareholder written notice of its intention,
describing the type of New Securities, the price and the general terms upon
which the Company proposes to issue the same.  Each Shareholder shall have
twenty (20) business days from the date of receipt of any such notice to agree
to purchase some or all of his Pro Rata Share of such New Securities for the
price and upon the general terms specified in the notice by giving written
notice to the Company and stating therein the quantity of New Securities to be
purchased.  Each Shareholder shall have a right of over-allotment such that if
any Shareholder fails to exercise his right hereunder to purchase his Pro Rata
Share of New Securities, the other Shareholders may purchase the non-purchasing
Shareholder's portion on a pro rata basis, within fifteen (15) business days
from the date such non-purchasing Shareholder fails to exercise his right
hereunder to purchase his Pro Rata Share of New Securities.

    (d)  In the event that the Shareholders fail to exercise in full the right
of first refusal within said twenty (20) plus fifteen (15) business day period,
the Company shall have one hundred twenty (120) days thereafter to sell (or
enter into an agreement pursuant to which the sale of New Securities covered
thereby shall be closed, if at all, within one hundred twenty (120) days from
the date of said agreement) the New Securities respecting which the
Shareholders' rights were not exercised, at a price and upon general terms no
more favorable to the purchasers thereof than specified in the Company's notice.
In the event the Company has not sold the New Securities within said one hundred
twenty (120) day period (or sold and issued New Securities in accordance with
the foregoing within one hundred twenty (120) days from the date of said
agreement), the Company shall not thereafter issue or sell any New Securities,
without first offering such securities to the Shareholders in the manner
provided above.

    (e)  The right of first refusal granted under this Section 3. 1 shall not
apply to and shall expire upon the closing of the Company's Initial Public
Offering.

                                         -16-


<PAGE>

    (f)  The rights granted pursuant to this Section 3.1 may be assigned by the
Shareholders (or by any permitted transferee of any such rights) so long as (i)
the Company is given notice of any such assignment within a reasonable time
after the date the same is effected and (ii) the transferee shall have acquired
(or, together with such transferee's Affiliates, after the acquisition shall
then beneficially own) at least 250,000 shares of Registrable Securities
(including shares of Series A Preferred and Series B Preferred prior to
conversion into Registrable Securities) in a private transaction.

                                      SECTION 4.

of at least a majority of the then outstanding shares of Registrable Securities,

shares consenting or not consenting) all shares previously disposed of by such
holders pursuant to one or more registration statements under the Securities Act

business as now conducted and as proposed to be conducted as described in the
Business Plan without any conflict with or infringement of the rights of others.
The Schedule of Exceptions contains a complete list of patents and pending
patent applications of the Company.  There are no outstanding options, licenses,
or agreements of any kind relating to the foregoing, nor is the Company bound by
or a party to any options, licenses, or agreements of any kind with respect to
the patents, trademarks, service marks, trade names, copyrights, trade secrets,

entity.  The Company is not aware that any of its employees or consultants are
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement or subject to any judgment, decree or order of
any court or administrative agreement that would interfere with the use of his,
her, or its best efforts to promote the best interests of the Company or that

best of the Company's knowledge, conflict with or result in a breach of the
terms, conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees or consultants is now
obligated.  The Company does not believe that it is or will be necessary to
utilize any inventions of any of its employees or consultants (or persons it
currently intends to hire) made prior to their employment by the Company.

or Bylaws or of any instrument, judgment, order, writ, decree or contract to
which it is a party or by which it is bound or, to its knowledge, of any
provision of federal or state statute, rule or regulation applicable to the
Company.  The execution, delivery and performance of this Agreement, the
Restated Investors' Rights Agreement or any Ancillary Agreements and the
consummation of the transactions contemplated hereby and thereby will not result
in any such violation or be in conflict with or constitute, with or without the
passage of time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an event which results
in the creation of any lien, charge or encumbrance upon any assets of the
Company or the suspension, revocation, impairment, forfeiture, or nonrenewal of
any material permit, license, authorization or approval applicable to the
Company, its business or operations or any of its assets or properties.

assets.  With respect to the property and assets it leases, the Company is in

subsequent to March 31, 1996 which in the aggregate do not exceed $25,000 and
(ii) obligations under contracts and commitments incurred in the ordinary course

Subsequent Investor, as applicable, hereby represents and warrants that:

         3.1  AUTHORIZATION.  This Agreement constitutes its valid and legally
binding obligation, enforceable in accordance with its terms.

         3.2  PURCHASE ENTIRELY FOR OWN ACCOUNT.  This Agreement is made with
each Investor in reliance upon such Investor's representation to the Company,
which by such Investor's execution of this Agreement such Investor hereby
confirms, that the Series B Preferred Stock to be received by such Investor and
the Common Stock issuable upon conversion thereof (collectively, the
"Securities") will be acquired for investment for such Investor's own account,
not as a nominee or agent, and not with a view to the resale or distribution of
any part thereof, and that such Investor has no present intention of selling,
granting any participation in or otherwise distributing the same.  By executing
this Agreement, each Investor further represents that such Investor does not
have any contract, undertaking, agreement or arrangement with any person to
sell, transfer or grant any participation to such person or to any third person,
with respect to any of the Securities.  Each Investor represents that it has
full power and authority to enter into this Agreement.

         3.3  DISCLOSURE OF INFORMATION.  It believes it has received all the
information it considers necessary or appropriate for deciding whether to
purchase the Series B Preferred Stock.  Each Investor further represents that it
has had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the offering of the Series B Preferred
Stock.  The foregoing, however, does not limit or modify the representations and
warranties of the Company in Section 2 of this Agreement or the right of the
Investors to rely thereon.

         3.4  INVESTMENT EXPERIENCE.  Each Investor is an investor in
securities of companies in the development stage and acknowledges that it is
able to fend for itself, can bear the economic risk of its investment and has

Preferred Stock.  If other than an individual, Investor also represents it has
not been organized for the purpose of acquiring the Series B Preferred Stock.

         3.5  ACCREDITED INVESTOR.   Each Investor is an "accredited investor"
within the meaning of Securities Exchange Commission ("SEC") Rule 501 of
Regulation D, as presently in effect.

         3.6  RESTRICTED SECURITIES.  It understands that the shares of
Series B Preferred Stock it is purchasing are characterized as "restricted
securities" under the federal securities laws inasmuch as they are being
acquired from the Company in a transaction not involving a public offering and
that under such laws and applicable regulations such securities may be resold
without registration under the Securities Act of 1933, as amended (the "Act"),
only in certain limited circumstances.  In this connection, each Investor
represents that it is familiar with SEC Rule 144, as presently in effect, and
understands the resale limitations imposed thereby and by the Act.

         3.7  FURTHER LIMITATIONS ON DISPOSITION.  Without in any way limiting
the representations set forth above, each Investor further agrees not to make
any disposition of all or any portion of the Series B Preferred Stock (or the
Common Stock issuable upon the conversion thereof) unless and until the
transferee has agreed in writing for the benefit of the Company to be bound by
this Section 3 and Section 7, provided and to the extent such sections are then
applicable, and the Rights Agreement and:

              (a)  There is then in effect a Registration Statement under the
Act covering such proposed disposition and such disposition is made in
accordance with such Registration Statement; or

              (b)(i)  Such Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, such Investor shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the Act.  It
is agreed that the Company will not require opinions of counsel for transactions
made pursuant to Rule 144 except in unusual circumstances.

              (c)  Notwithstanding the provisions of paragraphs (a) and (b)
above, no such registration statement or opinion of counsel shall be necessary
for a transfer by an Investor which is a partnership to a partner of such
partnership or a retired partner of such partnership who retires after the date
hereof, or to the estate of any such partner or retired partner or the transfer
by gift, will or intestate succession of any partner to his spouse or to the
siblings, lineal descendants or ancestors of such partner or his spouse, if the
transferee agrees in writing to be subject to the terms hereof to the same
extent as if he were an original Investor hereunder.

         3.8  LEGENDS.  It is understood that the certificates evidencing the
Series B Preferred Stock (and the Common Stock issuable upon conversion thereof)
may bear one or all of the following legends:

                                          OF
                           VISTA MEDICAL TECHNOLOGIES, INC.


    The undersigned, John Lyon and Larry Osterink, hereby certify that:

    ONE:  They are the duly elected and acting President and Secretary,
respectively, of Vista Medical Technologies, Inc., a California corporation.

    TWO:  The articles of incorporation of this corporation are amended and
restated to read as follows:


                                          I.

    The name of the corporation is Vista Medical Technologies, Inc.


                                         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.


                                         III.

    A.   CLASSES OF STOCK.  This corporation is authorized to issue two (2)
classes of shares, to be designated "Common" and "Preferred" and referred to
herein as the "Common Shares" or the "Preferred Shares" respectively.  The total
number of Common Shares the corporation is authorized to issue is twenty-five
million (25,000,000). The par value is $0.01 per share.  The total number of
Preferred Shares the corporation is authorized to issue is eighteen million
(18,000,000).  The par value is $0.01 per share.

         The board of directors of the corporation may divide the Preferred
Shares into any number of series.  The board of directors shall fix the
designation and number of shares of each such series.  The board of directors
may determine and alter the rights, preferences, privileges and restrictions
granted to and imposed upon any wholly unissued series of the Preferred Shares.
The board of directors (within the limits and restrictions of any resolution
adopted by it, originally fixing the number of shares of any series) may
increase or decrease the number of shares of any such series


                                         -1-

<PAGE>

after the issue of shares of that series, but not below the number of then
outstanding shares of such series.

    B.   RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF THE SERIES A-1
PREFERRED STOCK, SERIES A-3 PREFERRED STOCK AND SERIES B PREFERRED STOCK.

         1.   DESIGNATION OF SERIES A-1 PREFERRED STOCK, SERIES A-3 PREFERRED
STOCK AND SERIES B PREFERRED STOCK.  Eight Million Three Hundred Thousand
(8,300,000) shares of Preferred Stock are designated Series A-1 Preferred Stock
(the "Series A-1 Preferred") with the rights, preferences and privileges
specified herein.  Five Hundred Thousand (500,000) shares of Preferred Stock are
designated Series A-3 Preferred Stock (the "Series A-3 Preferred") with the
rights, preferences and privileges specified herein.  Three Million One Hundred
Thousand (3,100,000) shares of Preferred Stock are designated Series B Preferred
Stock (the "Series B Preferred") with the rights, preferences and privileges
specified herein.  As used in this Article III, Section B., the term "Series A
Preferred" shall refer to the Series A-1 Preferred and the Series A-3 Preferred.
As used in this Article III, Section B., the term "Preferred Stock" shall refer
to the Series A-1 Preferred, the Series A-3 Preferred and the Series B
Preferred.

         2.   DIVIDEND RIGHTS OF PREFERRED STOCK.  The holders of the then
outstanding shares of Preferred Stock shall be entitled to receive dividends pro
rata, in preference to any dividend on the Common Stock of this corporation
("Common"), at the rate of eight percent (8%) of the Original Purchase Price per
share (as defined below) per annum, whenever funds are legally available and
when and as declared by the Board of Directors.  The dividends shall be
non-cumulative.  The original purchase price of the Series A Preferred shall be
$1.325 per share (the "Series A Original Purchase Price").  The original
purchase price of the Series B Preferred shall be $4.00 per share (the "Series B
Original Purchase Price").  As used in this Section 2, the term "Original
Purchase Price" shall refer to the Series A Original Purchase Price or the
Series B Original Purchase Price, as the case may be.

         3.   LIQUIDATION PREFERENCE.

              a.   In the event of any liquidation event, either voluntary or
involuntary, the holders of the Preferred Stock shall be entitled to receive pro
rata, prior and in preference to any distribution of any of the assets or
surplus funds of the corporation to the holders of the Common by reason of their
ownership thereof, with respect to the Series B Preferred, the sum of (i) $4.00
per share for each share of Series B Preferred then held by them and (ii) an
amount equal to all declared but unpaid dividends on the Series B Preferred then
held by them, and, with respect to the Series A Preferred, the sum of (i) $1.325
per share for each share of Series A Preferred then held by them and (ii) an
amount equal to all declared but unpaid dividends on the Series A Preferred then
held by them.  If, upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Preferred Stock shall be insufficient to
permit the payment to such holders of the full aforesaid preferential amounts,
then the entire assets and funds of the corporation legally available for
distribution shall be distributed ratably among the holders of the Preferred
Stock in proportion to the preferential amount each such holder would have been
entitled to receive pursuant to this Section 3 if such distribution had been
sufficient to permit the full payment of such preferential amount.


                                         -2-

<PAGE>

              b.   After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Section
3.a. above, the holders of the Common and Preferred Stock shall be entitled to
receive the remaining assets of the corporation in proportion to the shares of
Common Stock then held by them and the shares of Common Stock which they have
the right to acquire upon conversion of Preferred Stock until such time as the
distributions made to the holders of the Preferred Stock (taken together with
all payments made pursuant to Section 3.a. above) equal, with respect to the
Series A Preferred, $3.975 per share for each share of Series A Preferred then
held by them and, with respect to the Series B Preferred, $12.00 per share for
each share of Series B Preferred then held by them.  If, upon the occurrence of
such event, the assets and funds thus distributed among the holders of the
Preferred Stock shall be insufficient to permit the payment to such holders of
the full aforesaid preferential amounts, then the entire remaining assets and
funds of the corporation legally available for distribution after payment has
been made to the holders of the Preferred Stock of the full amounts to which
they shall be entitled pursuant to Section 3.a. above shall be distributed
ratably among the holders of the Common and Preferred Stock in proportion to the
preferential amount each such holder would have been entitled to receive
pursuant to this Section 3 if such distribution had been sufficient to permit
the full payment of the preferential amounts under this Section 3.b. to the
holders of the Preferred Stock.

              c.   After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Sections
3.a. and 3.b. above, the holders of the Common shall be entitled to receive all
remaining assets of the corporation in proportion to the shares of Common Stock
then held by them.

              d.   For purposes of this Section 3, a liquidation, dissolution
or winding up of the corporation shall be deemed to be occasioned by, or to
include, the corporation's sale of all or substantially all of its assets or the
acquisition of this corporation by another entity by means of merger or
consolidation resulting in the exchange of the outstanding shares of this
corporation for securities or consideration issued, or caused to be issued, by
the acquiring corporation or its subsidiary in which the shareholders of the
corporation are holders of less than 50% of voting power of the surviving
corporation.

              e.   Each holder of any outstanding shares of Preferred Stock
shall be deemed to have consented, for purposes of Sections 502, 503 and 506 of
the California Corporations Code, to distributions made by the corporation in
connection with the repurchase of shares of Common issued to or held by
employees, directors or consultants of or to the corporation or any of its
subsidiaries upon termination of their employment or services pursuant to
agreements providing for the right of such repurchase between the corporation
and such persons.

         4.   CONVERSION.  The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

              a.   OPTIONAL AND AUTOMATIC CONVERSION.  Each share of Preferred
Stock shall be convertible at the option of the holder thereof, without payment
of additional consideration, at any time after the date of issuance of such
share, at the office of the corporation or any transfer agent for the Preferred
Stock, into such number of fully paid and nonassessable shares of Common as is
determined by dividing, with respect to the Series A Preferred, $1.325 or, with
respect to the Series B


                                         -3-

<PAGE>

Preferred, $4.00 by the Conversion Price, determined as hereinafter provided, in
effect at the time of conversion.  The price at which shares of Common shall be
deliverable upon conversion of the Series A-1 Preferred (the "Series A-1
Conversion Price") shall initially be $1.325 per share of Common.  The price at
which shares of Common shall be deliverable upon conversion of the Series A-3
Preferred (the "Series A-3 Conversion Price") shall initially be $1.325 per
share of Common.  The price at which shares of Common shall be deliverable upon
conversion of the Series B Preferred (the "Series B Conversion Price") shall
initially be $4.00 per share of Common.  As used in this Section 4., the term
"Conversion Price" shall refer to the Series A-1 Conversion Price, the
Series A-3 Conversion Price or the Series B Conversion Price, as the case may
be.  The initial Series A-1 Conversion Price, Series A-3 Conversion Price and
Series B Conversion Price shall be subject to adjustment as hereinafter
provided.

    Each share of Preferred Stock shall automatically be converted into shares
of Common at the then effective Conversion Price in the event of either (i) the
closing of a firm commitment underwritten public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended
(the "Act"), covering the offer and sale of Common (whether for the account of
the corporation or for the account of one or more shareholders of the
corporation) of the corporation to the public in which the aggregate gross cash
proceeds to the corporation (prior to underwriters' discounts and expenses) are
equal to or exceed $15,000,000 and the public offering price is equal to or
exceeds $5.00 per share of Common (as adjusted for any stock dividends,
combinations or splits with respect to such shares) (a "Qualified Public
Offering") or (ii) the written consent of holders of more than fifty percent
(50%) of the then outstanding shares of Preferred Stock voting together as a
single class (a "Qualifying Consent").  In the event of the automatic conversion
of the Preferred Stock upon a Qualified Public Offering, the conversion of
Preferred Stock shall be deemed to have occurred immediately prior to the
closing of such Qualified Public Offering.  In the event of the automatic
conversion of the shares of Preferred Stock upon a Qualifying Consent, the
conversion of Preferred Stock shall be deemed to have occurred on the date
specified in such Qualifying Consent.

              b.   MECHANICS OF CONVERSION.  No fractional shares of Common
shall be issued upon conversion of Preferred Stock.  In lieu of any fractional
shares to which the holder would otherwise be entitled, the corporation shall
pay cash equal to such fraction multiplied by the then effective Conversion
Price.  Before any holder of Preferred Stock shall be entitled to convert the
same into full shares of Common, it shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the corporation or of any
transfer agent for the Preferred Stock, and shall give written notice to the
corporation at such office that it elects to convert the same (except that no
such written notice of election to convert shall be necessary in the event of an
automatic conversion pursuant to Section 4.a.).  The corporation shall, as soon
as practicable thereafter, issue and deliver at such office to such holder of
Preferred Stock a certificate or certificates, registered in such names as
specified by the holder, for the number of shares of Common to which he shall be
entitled as aforesaid and a check payable to the holder in the amount of any
cash amounts payable as the result of a conversion into fractional shares of
Common, and any declared and unpaid dividends on the converted Preferred Stock.
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 Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Common on such date (except that in the
event of an automatic conversion (i) upon a Qualified Public Offering pursuant
to Section 4.a. such conversion shall be deemed to have been made immediately
prior to the closing of the Qualified Public


                                         -4-

<PAGE>

Offering and (ii) upon a Qualifying Consent pursuant to Section 4.a. such
conversion shall be deemed to have been made on the date specified in such
Qualifying Consent).  If the conversion is in connection with an underwritten
offering of securities registered pursuant to the Act, the conversion may, at
the option of any holder tendering Preferred Stock for conversion, be
conditioned upon the closing with the underwriter of the sale of securities
pursuant to such offering, in which event the person(s) entitled to receive the
Common issuable upon such conversion of the Preferred Stock shall not be deemed
to have converted such Preferred Stock until immediately prior to the closing of
such sale of securities.

              c.   ADJUSTMENTS TO SERIES A-1 CONVERSION PRICE, SERIES A-3
CONVERSION PRICE AND SERIES B CONVERSION PRICE FOR DILUTIVE ISSUES.

                   (1)  SPECIAL DEFINITIONS.  For purposes of this Section 4.c.
and Section 5, the following definitions shall apply:

                        (a)  "OPTION" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common or Convertible
Securities.

                        (b)  "ORIGINAL ISSUE DATE" shall mean, with respect to
the Series A-1 Preferred, the date on which a share of Series A-1 Preferred was
first issued, and with respect to the Series A-3 Preferred, the date on which a
share of Series A-3 Preferred was first issued, and with respect to the Series B
Preferred, the date on which a share of Series B Preferred was first issued.

                        (c)  "CONVERTIBLE SECURITIES" shall mean any evidences
of indebtedness, shares (other than Common and Preferred Stock) or other
securities directly or indirectly convertible into or exchangeable for Common.

                        (d)  "ADDITIONAL SHARES OF COMMON" shall mean all
shares of Common issued (or, pursuant to Section 4.c.(3), deemed to be issued)
by the corporation after the Original Issue Date, other than shares of Common
issued or issuable:

                             i)   upon conversion of shares of Preferred
Stock authorized herein;

                             ii)  to officers, directors or employees of,
or consultants to, the corporation pursuant to any plan or agreement approved by
the Board of Directors;

                             iii) as a dividend or distribution on the
Preferred Stock or any event for which adjustment is made pursuant to Sections
4.d. or 4.e. hereof;

                             iv)  in connection with equipment leasing or
bank financing transactions, provided such shares are issued for other than
primarily equity financing purposes;

                             v)   pursuant to transactions involving
technology licensing, research or development activities or the distribution or
manufacture of the corporation's products,


                                         -5-

<PAGE>

provided that each of the forgoing transactions is for other than primarily
equity financing purposes; or

                             vi)       by way of dividend or other distribution
on shares excluded from the definition of Additional Shares of Common by the
foregoing clauses i) through v) or this clause vi) or on shares of Common so
excluded.

                   (2)  NO ADJUSTMENT OF SERIES A-1 CONVERSION PRICE,
SERIES A-3 CONVERSION PRICE OR SERIES B CONVERSION PRICE.  No adjustment in the
Series A-1 Conversion Price, Series A-3 Conversion Price or Series B Conversion
Price shall be made in respect of the issuance of Additional Shares of Common
unless the consideration per share for an Additional Share of Common issued or
deemed to be issued by the corporation is less than the Series A-1 Conversion
Price, Series A-3 Conversion Price or Series B Conversion Price, respectively,
in effect on the date of, and immediately prior to, the issue of such Additional
Share.

                   (3)  ISSUE OF SECURITIES DEEMED ISSUE OF ADDITIONAL SHARES
OF COMMON -- OPTIONS AND CONVERTIBLE SECURITIES.  In the event the corporation
at any time or from time to time after the Original Issue Date shall issue any
Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common issuable
upon the exercise of such Options or, in the case of Convertible Securities and
Options therefor, the conversion or exchange of such Convertible Securities,
shall be deemed to be Additional Shares of Common issued as of the time of such
issue or, in case such a record date shall have been fixed, as of the close of
business on such record date, provided that in any such case in which Additional
Shares of Common are deemed to be issued:

                        (a)  no further adjustment in the Series A-1 Conversion
Price, Series A-3 Conversion Price or Series B Conversion Price shall be made
upon the subsequent issue of Convertible Securities or shares of Common upon the
exercise of such Options or conversion or exchange of such Convertible
Securities;

                        (b)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the corporation, or decreases in the number of shares
of Common issuable, upon the exercise, conversion or exchange thereof, the
Series A-1 Conversion Price, Series A-3 Conversion Price and Series B Conversion
Price computed upon the original issue thereof (or upon the occurrence of a
record date with respect thereto), and any subsequent adjustments based thereon,
shall, upon any such increase or decrease becoming effective, be recomputed to
reflect such increase or decrease insofar as it affects such Options or the
rights of conversion or exchange under such Convertible Securities;

                        (c)  no readjustment pursuant to clause (b) above shall
have the effect of increasing the Series A-1 Conversion Price, Series A-3
Conversion Price or Series B Conversion Price to an amount which exceeds the
lower of (i) such Series A-1 Conversion Price, Series A-3 Conversion Price or
Series B Conversion Price, respectively, on the original adjustment date with
respect to such deemed issuance of Additional Shares of Common, or (ii) such
Series A-1


                                         -6-

<PAGE>

Conversion Price, Series A-3 Conversion Price or Series B Conversion Price,
respectively, that would have resulted from any issuance of Additional Shares of
Common between such original adjustment date and such readjustment date; and

                        (d)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any decrease in the
consideration payable to the corporation upon the exercise, conversion or
exchange thereof, the Series A-1 Conversion Price, Series A-3 Conversion Price
and Series B Conversion Price computed upon the original issue thereof (or upon
the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such decrease becoming effective, be
recomputed to reflect such decrease insofar as it affects such Options or the
rights of conversion or exchange under such Convertible Securities.

                   (4)  ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF
ADDITIONAL SHARES OF COMMON.  In the event this corporation shall issue
Additional Shares of Common (including Additional Shares of Common deemed to be
issued pursuant to Section 4.c.(3)) without consideration or for a consideration
per share less than the Series A-1 Conversion Price, Series A-3 Conversion Price
or Series B Conversion Price in effect on the date of and immediately prior to
such issue, then and in such event, such Series A-1 Conversion Price, Series A-3
Conversion Price or Series B Conversion Price, respectively, shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying such Series A-1 Conversion Price, Series A-3
Conversion Price or Series B Conversion Price, respectively, by a fraction, the
numerator of which shall be the number of shares of Common outstanding
immediately prior to such issue plus the number of shares of Common which the
aggregate consideration received by the corporation for the total number of
Additional Shares of Common so issued would purchase at such Series A-1
Conversion Price, Series A-3 Conversion Price or Series B Conversion Price,
respectively, in effect immediately prior to such issue; and the denominator of
which shall be the number of shares of Common outstanding immediately prior to
such issue plus the number of such Additional Shares of Common so issued; and
provided further that, for the purposes of this Section 4.c.(4): (i) no shares
of Common issued or issuable upon conversion of Preferred Stock shall be deemed
to be outstanding and all such shares shall be excluded from such calculation,
(ii) all shares of Common issuable upon conversion of outstanding Options and
Convertible Securities (excluding outstanding Preferred Stock) shall be deemed
to be outstanding and all such shares shall be included in such calculation, and
(iii) except as provided in the foregoing clauses (i) and (ii) above,
immediately after any Additional Shares of Common are deemed issued pursuant to
Section 4.c.(3), such Additional Shares of Common shall be deemed to be
outstanding.  The Series A-1 Conversion Price, Series A-3 Conversion Price and
Series B Conversion Price shall not be increased except as set forth in Section
4.c.(3)(b) and in Section 4.d.

                   (5)  DETERMINATION OF CONSIDERATION.  For purposes of this
Section 4.c., the consideration received by the corporation for the issue of any
Additional Shares of Common shall be computed as follows:

                        (a)  CASH AND PROPERTY.  Such consideration shall:


                                         -7-

<PAGE>

                             i)        insofar as it consists of cash, be
computed at the aggregate amount of cash received by the corporation excluding
amounts paid or payable for accrued interest or accrued dividends;

                             ii)       insofar as it consists of property other
than cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                             iii)      in the event Additional Shares of Common
are issued together with other shares or securities or other assets of the
corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses i) and ii) above, as
reasonably determined in good faith by the Board of Directors.

                        (b)  OPTIONS AND CONVERTIBLE SECURITIES.  The
consideration per share received by the corporation for Additional Shares of
Common deemed to have been issued pursuant to Section 4.c.(3), relating to
Options and Convertible Securities, shall be determined by dividing:

                             i)        the total amount, if any, received or
receivable by the corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the corporation upon the exercise of such Options or
the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such Options for Convertible
Securities and the conversion or exchange of such Convertible Securities, by

                             ii)       the maximum number of shares of Common
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) issuable
upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.

              d.   ADJUSTMENT FOR STOCK SPLITS, DIVIDENDS AND COMBINATIONS.  If
the corporation shall at any time or from time to time effect a subdivision of
the outstanding Common, or shall issue a dividend of Common on its outstanding
Common, the Series A-1 Conversion Price, Series A-3 Conversion Price and
Series B Conversion Price then in effect immediately before that subdivision or
dividend shall be proportionately decreased, and conversely, if the corporation
shall combine the outstanding shares of Common, the Series A-1 Conversion Price,
Series A-3 Conversion Price and Series B Conversion Price then in effect
immediately before the combination shall be proportionately increased.  Any
adjustment under this Section 4.d. shall become effective at the close of
business on the date the subdivision or combination becomes effective or on the
date on which the dividend is declared.

              e.   ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the
event the corporation at any time or from time to time shall make or issue, or
fix a record date for the determination of holders of Common entitled to receive
a dividend or other distribution payable in securities of the corporation other
than shares of Common, then and in each such event provision shall


                                         -8-

<PAGE>

be made so that the holders of Series A-1 Preferred, Series A-3 Preferred and
Series B Preferred shall receive upon conversion thereof, in addition to the
number of shares of Common receivable thereupon, the amount of securities of the
corporation that they would have received had their Series A-1 Preferred, Series
A-3 Preferred and Series B Preferred been converted into Common on the date of
such event, giving effect to all adjustments called for with respect to such
securities during the period from the date of such event to and including the
conversion date.

              f.   ADJUSTMENT FOR MERGER OR REORGANIZATION.  In case of any
consolidation or merger of the corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the corporation to
another corporation (other than a consolidation, merger or conveyance provided
for elsewhere in this Section 4 or Section 3), provisions shall be made so that
holders of shares of Series A-1 Preferred, Series A-3 Preferred and Series B
Preferred shall thereafter be convertible into the number of shares of stock or
other securities or property to which a holder of the number of shares of Common
of the corporation deliverable upon conversion of such Series A-1 Preferred,
Series A-3 Preferred and Series B Preferred would have been entitled upon such
consolidation, merger or conveyance; and, in any case, appropriate adjustment
(as reasonably determined in good faith by the Board of Directors) shall be made
in the application of the provisions herein set forth with respect to the rights
and interest thereafter of the holders of the Series A-1 Preferred, Series A-3
Preferred and Series B Preferred, to the end that the provisions set forth
herein (including provisions with respect to changes in and other adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as reasonably
may be, in relation to any shares of stock or other property thereafter
deliverable upon the conversion of the Series A-1 Preferred, Series A-3
Preferred and Series B Preferred.

              g.   ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.
If the Common issuable upon the conversion of the Series A-1 Preferred,
Series A-3 Preferred and Series B Preferred shall be changed into the same or
different number of shares of any class or series of stock, whether by capital
reorganization, reclassification or otherwise (other than as set forth above in
this Section 4), then and in each such event the holder of each share of Series
A-1 Preferred, Series A-3 Preferred and Series B Preferred shall have the right
thereafter to convert such share into the kind and amount of shares of stock and
other securities and property receivable upon such reorganization,
reclassification or other change by holders of the number of shares of Common
into which such shares of Series A-1 Preferred, Series A-3 Preferred and Series
B Preferred might have been converted immediately prior to such reorganization,
reclassification or change, all subject to further adjustment as provided
herein.

              h.   NO IMPAIRMENT.  The corporation will not, by amendment of
this Amended and Restated 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 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-1 Preferred, Preferred, Series
A-3 Preferred and Series B Preferred against impairment.

              i.   CERTIFICATE AS TO ADJUSTMENTS.  Upon the occurrence of each
adjustment or readjustment of the Series A-1 Conversion Price, Series A-3
Conversion Price or Series B Conversion


                                         -9-

<PAGE>

Price pursuant to this Section 4, the corporation at its expense shall promptly
compute such adjustments or readjustments in accordance with the terms hereof
and furnish to each holder of any such Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based.  The corporation shall, upon the
written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Series A-1 Conversion Price, Series A-3
Conversion Price or Series B Conversion Price at the time in effect, and
(iii) the number of shares of Common and the amount, if any, of other property
which at the time would be received upon the conversion of such holder's shares.

              j.   NOTICES OF RECORD DATE.  In the event of any taking by the
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 which is the same as cash dividends paid in
previous quarters) or other distribution, the corporation shall mail to each
holder of Preferred Stock at least ten (10) 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 or distribution.  Each such written notice
shall be given by first class mail, postage prepaid, addressed to the holders of
Preferred Stock at the address for each such holder as shown on the books of
this corporation.

              k.   COMMON STOCK RESERVED.  The corporation shall at all times
reserve and keep available out of its authorized but unissued shares of Common,
solely for the purpose of effecting the conversion of the shares of Preferred
Stock, such number of shares of Common as shall from time to time be sufficient
to effect the conversion of all outstanding shares of Preferred Stock, and if at
any time the number of authorized but unissued shares of Common shall not be
sufficient to effect the conversion of all then outstanding shares of Preferred
Stock, the corporation shall take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of
Common to such number of shares as shall be sufficient for such purpose.

         5.   VOTING RIGHTS.  Each holder of shares of Series A-1 Preferred
shall be entitled to the number of votes equal to the number of shares of Common
into which such shares of Series A-1 Preferred could be converted on the record
date for the vote or the date of the solicitation of any written consent of
shareholders and shall have voting rights and powers equal to the voting rights
and powers of the Common.  The Series A-3 Preferred shall be non-voting
Preferred, except as otherwise required by law.  Each holder of shares of Series
B Preferred shall be entitled to the number of votes equal to the number of
shares of Common into which such shares of Series B Preferred could be converted
on the record date for the vote or the date of the solicitation of any written
consent of shareholders and shall have voting rights and powers equal to the
voting rights and powers of the Common.  Each holder of Common shall be entitled
to one vote per share of Common held by such holder.  The holder of each share
of Series A-1 Preferred and Series B Preferred shall be entitled to notice of
any shareholders' meeting in accordance with the Bylaws of the corporation and
shall vote with holders of the Common upon all matters submitted to a vote of
shareholders, except those matters required by law to be submitted to a class
vote and except as provided in Section 6 below.  Fractional votes by the holders
of Series A-1 Preferred and Series B Preferred shall not, however, be permitted
and any fractional voting rights resulting from the above formula shall be
rounded to the nearest whole number.

                   (1)  amend or repeal any provision of, or add any provision

Series A-1 Preferred or Series B Preferred;

                   (2)  create any new series or class of stock having any

employment, and (ii) as approved by the Board of Directors);

                   (5)  merge into or consolidate with any other corporation or
entity (other than any transaction in which the corporation's shareholders own a
majority of the securities of the surviving corporation) or sell all or
substantially all of the assets of the corporation;

                   (6)  amend, or take any action intended to circumvent, the
provisions of this Section 6.

         7.   STATUS OF CONVERTED STOCK.  In the event any shares of Preferred
Stock shall be converted pursuant to Section 4 hereof, the shares so converted
shall be cancelled and shall not be issuable by the corporation.  The Articles
of Incorporation of this corporation shall be appropriately amended to effect
the corresponding reduction in the corporation's authorized capital stock.

         8.   RESIDUAL RIGHTS.  All rights accruing to the outstanding shares
of the corporation not otherwise expressly provided for in this Amended and
Restated Articles of Incorporation shall be vested in the Common.

                   AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT


    THIS AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT (the "AGREEMENT") is
made as of the 12th day of July, 1996, by and between Vista Medical
Technologies, Inc., a California corporation (the "Company"), and the
Shareholders listed on Schedule A hereto, each of which is herein referred to as
a "Shareholder."

                                       RECITALS

    WHEREAS, the Company and certain of the Shareholders (the "SERIES A
SHAREHOLDERS") are parties to a certain Investors Rights Agreement dated as of
July 27, 1995, as amended on September 15, 1995 (the "PRIOR AGREEMENT"),
pursuant to which the Company has agreed to the extent possible to grant to the
Series A Shareholders certain rights to cause the Company to register shares of
Common Stock issuable to the Series A Shareholders upon conversion of the
Company's Series A-1 Preferred Stock and Series A-3 Preferred Stock (the "SERIES
A PREFERRED") in the event the Company grants such rights to other shareholders,
and certain other matters as set forth therein;

    WHEREAS, the Company and certain of the Shareholders (the "SERIES B
SHAREHOLDERS") are parties to the Series B Preferred Stock Purchase Agreement of
even date herewith (the "SERIES B AGREEMENT"); and

    WHEREAS, in order to induce the Company to enter into the Series B
Agreement and to induce the Series B Shareholders to purchase shares of the
Company's Series B Preferred Stock (the "SERIES B PREFERRED") pursuant to the
Series B Agreement, the Shareholders and the Company hereby agree that this
Agreement shall amend and restate the Prior Agreement so that this Agreement
shall govern the obligations of the Company to register the resale of shares of
Common Stock issuable to the Shareholders upon conversion of their shares of the
Company's Series A Preferred and/or Series B Preferred, and certain other
matters as set forth herein.

    NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

opinion of counsel to the Company satisfactory to comply with the provisions of
the Securities Act.  Except for transfers made pursuant to Rule 144 of the
Securities Act, the Shareholders will cause any proposed transferee of Series A
Preferred, Series B Preferred or Registrable Securities held by any Shareholder
to agree to take and hold such securities subject to the provisions and upon the
conditions specified in this Agreement and it will be a condition precedent to
the effectiveness of any such transfer that the


                                          1

    OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION.

    (b)  Each certificate representing shares of Registrable Securities into
which shares of the Series A Preferred and/or Series B Preferred are converted
also shall be stamped or otherwise imprinted with any legend required by the
Bylaws of the Company (in addition to any legend required under applicable
California or other state securities laws).

    1.4  NOTICE OF PROPOSED TRANSFERS.  The holder of each certificate
representing the Restricted Securities, by acceptance thereof, agrees to comply
in all respects with the provisions of this Section 1.4. Prior to any proposed
transfer of any Restricted Securities, unless there is in effect a registration
statement under the Securities Act covering the proposed transfer, the holder
thereof shall give written notice to the Company of such holder's intention to
effect such transfer.  Each such notice shall describe the manner and
circumstances of the proposed transfer in sufficient detail, and shall be
accompanied (except in transactions in compliance with Rule 144) by either (i) a
written opinion of legal counsel which shall be reasonably satisfactory to the
Company addressed to the Company and reasonably satisfactory in form and
substance to the Company's counsel, to the effect that the proposed transfer of
the Restricted Securities may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission, a copy of any
holder's request (together with all supplements or amendments thereto) to which
shall have been provided to the Company, at or prior to the time of first
delivery to the Commission's staff, to the effect that the transfer of such
securities without registration will not result in a recommendation by such
staff that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company.  Each certificate evidencing the Restricted Securities transferred as
provided for above shall bear the appropriate restrictive legend set forth in
Section 1.3 above, except that such certificate shall not bear such restrictive
legend if, in the opinion of counsel for the Company or counsel for such holder,
such legend is not required in order to establish compliance with any provisions
of the Securities Act.

    Notwithstanding the provisions above, no such opinion of counsel or "no
action letter" shall be necessary for a transfer by a Shareholder which is a
partnership to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such
partner or retired partner ("PARTNERS"), if the transferee agrees in writing to
be subject to the terms hereof to the same extent as if he were an original
Shareholder hereunder.

    1.5  DEMAND REGISTRATION RIGHTS.


                                          3


<PAGE>

    (a)  Commencing on July 12, 1999, if the Company shall receive a written
request (specifying that it is being made pursuant to this Section 1.5) from the
Holders of at least forty percent (40%) of the Registrable Securities that the
Company file a registration statement or similar document under the Securities
Act covering the registration of Registrable Securities the expected aggregate
offering price to the public of which is at least $7,500,000, then the Company
shall promptly notify all other Holders of such request and shall use its best
efforts to cause all Registrable Securities that such Holders have requested,
within fifteen (15) days after receipt of such written notice, to be registered
in accordance with this Section 1.5 to be registered under the Securities Act.
The Holders making the written request pursuant to this Section 1.5 shall be
referred to hereinafter as the "INITIATING HOLDERS".

    Notwithstanding the foregoing, (i) the Company shall not be obligated to
effect a registration pursuant to this Section 1.5 during the period starting
with the date one hundred twenty (120) days prior to the Company's estimated
date of filing of, and ending on a date one hundred eighty (180) days following
the effective date of, a registration statement pertaining to an underwritten
public offering of the Company's securities, provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective and that the Company's estimate of
the date of filing such registration statement is made in good faith; and (ii)
if the Company shall furnish to such Holders a certificate signed by the
President of the Company stating that in the good faith judgment of the Board of
Directors it would be seriously detrimental to the Company or its shareholders
for a registration statement to be filed in the near future, then the Company's
obligation to use its best efforts to file a registration statement shall be
deferred for a period not to exceed six (6) months; provided, however, that the
Company shall not obtain such a deferral more than once in any 12-month period.

    The Company shall be obligated to effect not more than two (2)
registrations pursuant to this Section 1.5 for which holders of Registrable
Securities are the Initiating Holders.

    (b)  If the Initiating Holders intend to distribute the Registrable
Securities covered by their demand by means of an underwriting, they shall so
advise the Company as part of their demand made pursuant to this Section 1.5,
and the Company shall include such information in the notice referred to in
Section 1.5(a). In such event, the right of any Holder to registration pursuant
to this Section 1.5 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder) to the extent provided herein.

    The Company shall, together with all Holders proposing to distribute their
securities through such underwriting, enter into an underwriting agreement in
customary form with the underwriter or underwriters selected by the Company and
reasonably satisfactory to a majority of interest of the Initiating Holders.
Notwithstanding any other provision of this Section 1.5, if the underwriter
shall advise the Company in writing that marketing factors (including, without
limitation, an adverse effect on the per share offering price) require a
limitation of the number of shares to be underwritten, then the Company shall so
advise all Holders of Registrable Securities that would otherwise be registered
and underwritten pursuant hereto, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated pro rata among such Holders thereof in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement.  No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.


                                          4


<PAGE>

    If any Holder disapproves of the terms of the underwriting, such Holder may
elect to withdraw therefrom by written notice to the Company, the underwriter
and the Initiating Holders.  The Registrable Securities so withdrawn shall also
be withdrawn from registration.  If by the withdrawal of such Registrable
Securities a greater number of Registrable Securities held by other Holders may
be included in such registration (up to the maximum of any limitation imposed by
the underwriters), then the Company shall offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used in determining the
underwriter limitation in this Section 1.5.

    If the underwriter has not limited the number of Registrable Securities to
be underwritten, the Company may include securities for its own account (or for
the account of other securityholders) in such registration if the underwriter so
agrees and if the number of Registrable Securities that would otherwise have
been included in such registration and underwriting will not thereby be limited.

    1.6  COMPANY REGISTRATION.

    (a)  If, at any time or from time to time, the Company shall determine to
register any of its securities, either for its own account or the account of a
securityholder or holders exercising their respective demand registration
rights, other than a registration relating solely to employee benefit plans on
Form S-8 or similar forms which may be promulgated in the future or a
registration on Form S-4 or similar forms which may be promulgated in the future
relating solely to a Securities and Exchange Commission Rule 145 or similar
transaction the Company will (i) promptly give to each Holder written notice
thereof and (ii) include in such registration (and any related qualification
under Blue Sky laws or other compliance), and in any underwriting involved
therein, all Registrable Securities of such Holders as specified in a written
request or requests made within fifteen (15) days after receipt of such written
notice from the Company.

    (b)  If the registration of which the Company gives notice is for a
registered public offering involving an underwriting, the Company shall so
indicate in the notice given pursuant to Section 1.6(a). In such event the right
of any Holder to registration pursuant to this Section 1.6 shall be conditioned
upon such Holder's agreeing to participate in such underwriting and to the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.  All Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other Holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company or by other holders exercising any
demand registration rights.  Notwithstanding any other provision of this Section
1.6, if the underwriter determines that marketing factors require a limitation
of the number of shares to be underwritten, the underwriter may exclude some or
all Registrable Securities or other securities from such registration and
underwriting (hereinafter an "UNDERWRITER CUTBACK"); provided, however, that if
such underwriting relates to any registration statement other than a
registration statement being filed with respect to the first registration
statement filed by the Company covering an underwritten offering of any of its
securities to the general public ("INITIAL PUBLIC OFFERING") in which no
secondary shares are included, then (i) in no event shall the aggregate number
of shares of Registrable Securities included in such underwriting be reduced
below thirty (30%) of the total number of shares proposed to be included in such
underwriting.  In the event of an Underwriter Cutback, the Company shall so
advise all Holders and the other holders distributing their securities through
such underwriting, and the number of Registrable Securities and other securities
that may be included in the


                                          5


<PAGE>

registration and underwriting shall be allocated among all holders thereof
(other than those holders who are exercising their demand registration rights)
on the basis that the holders who are not Holders shall be cut back before any
cutback of Holders.  If the limitation determined by the underwriter requires an
Underwriter Cutback, such Underwriter Cutback shall be in proportion, as nearly
as practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement.  If any Holder
disapproves of the terms of any such underwriting, such Holder may elect to
withdraw therefrom by written notice to the Company and the underwriter.  Any
securities excluded or withdrawn from such underwriting shall be withdrawn from
such registration.

    1.7  FORM S-3 REGISTRATION RIGHTS.  After the Initial Public Offering, the
Company shall use its best efforts to qualify for registration on Form S-3, and
to that end the Company shall use its best efforts to comply with the reporting
requirements of the Securities Exchange Act of 1934, as amended (the "EXCHANGE
ACT"), within twelve (12) months following the effective date of the first
registration of any securities of the Company for an underwritten registered
public offering.  After the Company has qualified for the use of Form S-3, and
subject to the provisions of Section 1.14, each Holder shall have the right to
request registrations on Form S-3 (such requests shall be in writing and shall
state the number of shares of Registrable Securities to be disposed of and the
intended method of disposition of such shares by each such Holder), subject only
to the following limitations:

    (a)  The Company shall not be obligated to cause a registration on Form S-3
to become effective prior to one hundred eighty (180) days following the
effective date of a Company initiated registration (other than a registration
effected solely to qualify an employee benefit plan or to effect a business
combination pursuant to Rule 145);

    (b)  The Company shall not be required to effect a registration pursuant to
this Section 1.7 unless the Holder or Holders requesting such a registration
propose to dispose of shares of Registrable Securities having an aggregate
disposition price (before deduction of underwriting discounts and expenses of
sale) of at least $500,000;

    (c)  The Company shall not be required to effect a registration pursuant to
this Section 1.7 if the Company shall furnish to the requesting Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company or its shareholders for the registration statement to
be filed at the date filing would be required, in which case the Company shall
have an additional period of not more than one hundred twenty (120) days within
which to file such registration statement; provided however, that the Company
shall not use this right more than once in any 12-month period;

    (d)  The Company shall not be required to maintain and keep any such
registration on Form S-3 effective for a period exceeding one hundred twenty
(120) days from the effective date thereof;

    (e)  The Company shall not be obligated to cause a registration on Form S-3
if in the prior six-month period the Company has caused a registration on Form
S-3 to become effective; and

    (f)  The Company shall be obligated to effect not more than two
registrations per year pursuant to this Section 1.7 for which holders of
Registrable Securities request such registration.


                                          6


<PAGE>

    The Company shall give notice to all Holders of the receipt of a request
for registration pursuant to this Section 1.7 and shall use its best efforts to
cause all Registrable Securities that such Holders have requested, within
fifteen (15) days after receipt of such written notice, be registered in
accordance with this Section 1.7 to be registered under the Securities Act.
Subject to the foregoing, the Company will use its best efforts to effect
promptly any registration pursuant to this Section 1.7. The provisions of
Section 1.5(b) shall apply to any registration effected pursuant to this Section
1.7

    1.8  EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Sections 1.5, 1.6 and 1.7 (exclusive of Selling Expenses but inclusive of the
reasonable fees and expenses of one special counsel to the selling Holders)
shall be borne by the Company.  Notwithstanding anything to the contrary herein,
the Company shall not be required to pay for any expenses of any registration
proceeding under Section 1.5 if the registration request is subsequently
withdrawn at the request of the Holders of a majority of the Registrable
Securities to have been registered, unless such Holders agree to forfeit their
right to a demand registration pursuant to Section 1.5 (in which event such
right shall be forfeited by all Holders).  In the absence of such an agreement
to forfeit, the Holders of Registrable Securities to have been registered shall
bear all such expenses pro rata on the basis of the Registrable Securities to
have been registered.  Notwithstanding the foregoing, however, if at the time of
the withdrawal, the Holders have learned of a material adverse change in the
condition, business or prospects of the Company from that known to the Holders
at the time of their request, of which the Company had knowledge at the time of
the request, then the Holders shall not be required to pay any of said expenses
and shall retain their rights pursuant to Section 1.5.

    1.9  REGISTRATION PROCEDURES.  In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder 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:

    (a)  Keep such registration, qualification or compliance effective for a
period of one hundred twenty (120) days or until the Holder or Holders have
completed the distribution described in the registration statement relating
thereto, whichever first occurs;

    (b)  Prepare and file with the Commission 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;

    (c)  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 they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them;

    (d)  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 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;


                                          7


<PAGE>

    (e)  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 Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement; and

    (f)  Notify each Holder of Registrable Securities covered by 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.

    Notwithstanding any provision to the contrary in this Agreement, the
Company shall not be required in connection with any registration pursuant to
Sections 1.5, 1.6 or 1.7 to qualify shares in any state or jurisdiction which
requires the Company to qualify to do business or to file a general consent to
service of process.

    1.10 INDEMNIFICATION.

    (a)  The Company will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Section 1, and
each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, 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, in
light of the circumstances in which they were made, not misleading, or any
violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will promptly reimburse each such Holder, each of its
officers and directors and partners, and each person controlling such Holder,
each such underwriter and each person who controls any such underwriter, for any
legal and any other expenses reasonably incurred (as and when incurred) in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder or underwriter and stated to be specifically for use therein.

    (b)  Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify 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 or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and


                                          8


<PAGE>

directors and partners and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof) including any of
the foregoing incurred in settlement of any litigation commenced or threatened,
arising out of or based on any untrue statement (or alleged untrue statement) of
a material fact contained in any such registration statement, prospectus,
offering circular or other document, or any amendment or supplement thereto,
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, in the light of the
circumstances in which they were made, not misleading, or any violation by the
Company of any rule or regulation promulgated under the Securities Act
applicable to the Company in connection with any such registration,
qualification, or compliance, and will promptly reimburse the Company, such
Holders, such directors, officer's, partners, persons, underwriters or control
persons for any legal or any other expenses reasonably incurred (as and when
incurred) in connection with investigation, preparing or defending 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 or any amendment or supplement
thereto in reliance upon and in conformity with written information furnished to
the Company by an instrument duty executed by such Holder and stated to be
specifically for use therein, provided, however, that the obligations of each
such Holder hereunder shall be limited to an amount equal to the proceeds to
each such Holder of Registrable Securities sold as contemplated herein.

    (c)  Each party entitled to indemnification under this Section 1.10 (the
"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, and shall
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
withheld), and the Indemnified Party may participate in such defense at its own
expense, and provided further that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 1 unless such failure resulted in actual
detriment to the Indemnifying Party.  No Indemnifying Party, in the defense of
any such claim or litigation, shall, except with the consent of each 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 a release from all liability in respect of
such claim or litigation.

    (d)  If the indemnification provided for in this Section 1.10 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations.  The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Indemnifying Party or by the Indemnified
Party and the parties relative


                                          9


<PAGE>

intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission.

    (e)  The obligations of the Company and Holders under this Section 1.10
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1 and otherwise.

    1.11 INFORMATION BY HOLDER.  The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Section 1.

    1.12 RULE 144 REPORTING.  With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the Restricted Securities to the public without registration, after such
time as a public market exists for the Common Stock of the Company, the Company
agrees to:

    (a)  Use its best efforts to make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act at
all times after the effective date of the first registration under the
Securities Act filed by the Company for an offering of its securities to the
general public;

    (b)  Use its best efforts to then file with the Commission in a timely
manner all reports and other documents required of the Company under the
Exchange Act at any time after it has become subject to such reporting
requirements,

    (c)  So long as a Shareholder owns any Restricted Securities, to furnish to
the Shareholder forthwith upon 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 general 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 report of the
Company, and such other reports and documents of the Company as a Shareholder
may reasonably request in availing itself of any rule or regulation of the
Commission allowing a Shareholder to sell any such securities without
registration.

    1.13 TRANSFER OF REGISTRATION RIGHTS.  The rights to cause the Company to
register securities granted under Sections 1.5, 1.6 and 1.7 may be assigned or
otherwise conveyed to a transferee or assignee of Registrable Securities, who
shall be considered a "Holder," and the transferred shares shall be considered
"Registrable Securities," for purposes of this Section 1, provided that (i) said
transferee acquires (or, together with affiliates (as defined under the
Securities Act) ("AFFILIATES") of said transferee, after the acquisition then
beneficially owns) at least 250,000 shares of the Registrable Securities
(including shares of Series A Preferred and Series B Preferred prior to
conversion into Registrable Securities) and (ii) the Company is given written
notice by such Holder at the time of or within a reasonable time (but not more
than thirty (30) days) after said transfer, stating the name and address of said
transferee or assignee and identifying the securities with respect to which such


                                          10


<PAGE>

registration rights are being assigned, subject to said transferee's agreement
to be bound by and comply with the provisions of this Section 1.

    1.14 TERMINATION OF REGISTRATION RIGHTS.  The registration rights granted
pursuant to this Section 1 shall terminate (i) upon the seventh anniversary of
the effective date of the first registration statement filed by the Company
covering the Initial Public Offering or (ii) if earlier, as to any individual
Holder, at such time after the Company's Initial Public Offering as all
Registrable Securities (including shares of Series A Preferred and Series B
Preferred prior to conversion into Registrable Securities) held by such Holder
can be sold within any three-month period without compliance with the
registration requirements of the Securities Act pursuant to Rule 144 (including
Rule 144(k)) promulgated thereunder.

    1.15 "MARKET STAND OFF" AGREEMENT.  Each Holder hereby agrees that, during
the period of duration specified by the Company and an underwriter of common
stock or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Act, it shall not, to the
extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it at any time during such period except common stock included in such
registration; PROVIDED, HOWEVER, that:

              (a)  such agreement shall not exceed 180 days for the first such
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

              (b)  such agreement shall not exceed 90 days for any subsequent
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;
and

              (c)  all executive officers and directors of the Company and all
other persons with registration rights under this Agreement enter into similar
agreements.

              In order to enforce the foregoing covenant, the Company may
impose stop-transfer instructions with respect to the Registrable Securities of
each Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.  Notwithstanding the
foregoing, the obligations described in this Section 1.15 shall not apply to a
registration relating solely to employee benefit plans on Form S-8 or similar
forms which may be promulgated in the future, or a registration relating solely
to a SEC Rule 145 transaction on Form S-14 or Form S-15 or similar forms which
may be promulgated in the future.

                                      SECTION 2.

                AFFIRMATIVE COVENANTS OF THE COMPANY AND SHAREHOLDERS

    2.1  FINANCIAL INFORMATION.  Subject to Section 2.3, the Company will
furnish the following reports to the Shareholders for so long as the
Shareholders are holders of any Series A Preferred, Series B Preferred or
Registrable Securities:


                                          11


<PAGE>

    2.2  ASSIGNMENT OF RIGHTS TO FINANCIAL INFORMATION.  The rights granted

transferee of any such rights) so long as (i) the Company is given notice of any
such assignment within a reasonable time after the date the same is effected,

Affiliates, after the acquisition shall then beneficially own) at least 250,000

competitive with the Company.

    2.3  INSPECTION RIGHTS.

    (a)  The Company will permit any Investor, so long as such Investor (or its

thereof (as presently constituted and subject to subsequent adjustment for stock
splits, stock dividends, reverse stock splits, recapitalizations and the like)
(a "SIGNIFICANT HOLDER") (or a representative of any Significant Holder) to
visit and inspect any of the properties of the Company, including its books of
account and other records (and make copies thereof and take extracts therefrom),
and to discuss its affairs, finances and accounts with the Company's officers
and its independent public accountants, all at such reasonable times and as
often as any such person may reasonably request.

    (b)  The provisions of Section 2.2 and this Section 2.3 shall not be in

    2.4  ATTENDANCE AT BOARD MEETINGS.  So long as Kaiser Aerospace &
Electronics ("Kaiser") owns at least an aggregate of 1,000,000 shares of Series
A Preferred, and so long as Kaiser does not have a representative on the Board
of Directors of the Company, Kaiser shall receive from the Company notices of
all meetings of the Board of Directors, including without limitation telephonic
meetings, and Kaiser shall receive, with such limitations provided herein, any
materials distributed for such meeting, and may send one representative to such
meetings, PROVIDED, HOWEVER, that the Company may require as a condition
precedent that such representative proposing to attend any meeting of the Board
of Directors shall agree to hold in confidence and trust and to act in a
fiduciary manner with respect to all information so received during such
meetings and may require that such representative sign a confidentiality
agreement with the Company; and, PROVIDED, FURTHER, that the Company reserves
the right not to provide information and to exclude such representative from any
meeting or portion thereof if attendance at such meeting by such representative
or dissemination of any information at such meeting to such representative
would, in the good faith judgment of the Board of Directors, result in
disclosure of trade secrets to such representative, would compromise or
adversely affect the attorney-client privilege between the Company and its
counsel, or would, in the good faith judgment of the Board of Directors, result
in a conflict of interest situation.  If such representative in his or her good
faith judgment believes that an item to be discussed by the Board of Directors
would result in any conflict of interest, such representative shall promptly
bring such conflict to the attention of the Chairman of the Board.  In no event
shall any provision of this paragraph waive any obligation of confidentiality to
the Company owed by any such representative or Kaiser.

    2.5  TERMINATION OF COVENANTS.  The covenants set forth in Section 2.1,
Section 2.3 and Section 2.4 shall terminate and be of no further force or effect
after the closing date of the Initial Public Offering.

    2.6  CONFIDENTIAL INFORMATION, ETC.  Each Shareholder agrees that all
information received by it pursuant to this Section 2, and any other information
relating to the Company's technology, processes or formulas that is disclosed by
the Company to any Shareholder in writing and is marked "Confidential," shall be
considered confidential information.  Each Shareholder further agrees that it
shall hold all such confidential information in confidence and shall not
disclose any such confidential information to any third party other than its
counsel or accountants nor shall such Shareholder use such confidential
information for any purpose other than evaluation of such Shareholder's
investment in the Company; provided, however, that the foregoing obligation to
hold in confidence and not to disclose confidential information shall not apply
to any such information that (a) was known to the public prior to disclosure by
the Company, (b) becomes known to the public through no fault of such
Shareholder, (c) is disclosed to such Shareholder on a non-confidential basis by
a third party having a legal right to make such disclosure or (d) is
independently developed by such Shareholder.

                                      SECTION 3.

                               RIGHTS OF FIRST REFUSAL

    3.1  RIGHT OF FIRST REFUSAL ON COMPANY ISSUANCES.

    (a)  The Company hereby grants to each Shareholder the right of first
refusal to purchase its Pro Rata Share (defined below) of all (or any part) of
New Securities (defined below) that the Company may from time to time propose to
sell and issue.  Such Shareholder's "PRO RATA SHARE," for purposes


                                          13


<PAGE>

of this Section 3, is the ratio of the number of shares of Common Stock
(assuming conversion of all shares of Series A Preferred and Series B Preferred)
then held by such Shareholder to the total number of shares of Common Stock then
outstanding (assuming conversion of all shares of Series A Preferred and Series
B Preferred).  This right of first refusal shall be subject to the following
provisions:

    (b)  "NEW SECURITIES" shall mean any Common Stock or Preferred Stock of the
Company, whether now authorized or not, and rights, options, or warrants to
purchase said Common Stock or Preferred Stock, and securities of any type
whatsoever that are, or may become, convertible into or exchangeable for said
Common Stock or Preferred Stock; provided, however, that "NEW SECURITIES" does
not include (i) securities issuable upon conversion of or with respect to Series
A Preferred Stock, Series B Preferred Stock or any future series of preferred
stock; (ii) shares of the Company's Common Stock (or related options) issued to
officers, directors, employees of and/or consultants to the Company pursuant to
plans or agreements as approved by the Company's Board of Directors; (iii)
shares of the Company's Common Stock or Preferred Stock issued in connection
with any stock split, stock dividend, or recapitalization by the Company; (iv)
securities issued in connection with any equipment leasing, technology
licensing, corporate partnering, strategic alliance, acquisition, merger,
purchase of assets or similar transaction as approved by the Company's Board of
Directors; and (v) shares of the Company's Common Stock issued or issuable as a
result of any antidilution adjustment provided for in the Company's Articles of
Incorporation as in effect at the time of such issuance.

    (c)  In the event that the Company proposes to undertake an issuance of New
Securities, it shall give each Shareholder written notice of its intention,
describing the type of New Securities, the price and the general terms upon
which the Company proposes to issue the same.  Each Shareholder shall have
twenty (20) business days from the date of receipt of any such notice to agree
to purchase some or all of his Pro Rata Share of such New Securities for the
price and upon the general terms specified in the notice by giving written
notice to the Company and stating therein the quantity of New Securities to be
purchased.  Each Shareholder shall have a right of over-allotment such that if
any Shareholder fails to exercise his right hereunder to purchase his Pro Rata
Share of New Securities, the other Shareholders may purchase the non-purchasing
Shareholder's portion on a pro rata basis, within fifteen (15) business days
from the date such non-purchasing Shareholder fails to exercise his right
hereunder to purchase his Pro Rata Share of New Securities.

    (d)  In the event that the Shareholders fail to exercise in full the right
of first refusal within said twenty (20) plus fifteen (15) business day period,
the Company shall have one hundred twenty (120) days thereafter to sell (or
enter into an agreement pursuant to which the sale of New Securities covered
thereby shall be closed, if at all, within one hundred twenty (120) days from
the date of said agreement) the New Securities respecting which the
Shareholders' rights were not exercised, at a price and upon general terms no
more favorable to the purchasers thereof than specified in the Company's notice.
In the event the Company has not sold the New Securities within said one hundred
twenty (120) day period (or sold and issued New Securities in accordance with
the foregoing within one hundred twenty (120) days from the date of said
agreement), the Company shall not thereafter issue or sell any New Securities,
without first offering such securities to the Shareholders in the manner
provided above.

    (e)  The right of first refusal granted under this Section 3. 1 shall not
apply to and shall expire upon the closing of the Company's Initial Public
Offering.


                                          14


<PAGE>

    (f)  The rights granted pursuant to this Section 3.1 may be assigned by the
Shareholders (or by any permitted transferee of any such rights) so long as (i)
the Company is given notice of any such assignment within a reasonable time
after the date the same is effected and (ii) the transferee shall have acquired
(or, together with such transferee's Affiliates, after the acquisition shall
then beneficially own) at least 250,000 shares of Registrable Securities
(including shares of Series A Preferred and Series B Preferred prior to
conversion into Registrable Securities) in a private transaction.

                                      SECTION 4.

registered or certified mail, postage prepaid, or otherwise delivered by hand or
by messenger, addressed (a) if to the Shareholders, to such Shareholders'
addresses set forth on the Schedule of Shareholders or to such other address as
such Shareholders shall have furnished to the Company in writing, (b) if to any

unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic benefit of this Agreement to any party.

enforceability with respect to any Shareholder of any one or more of the
provisions of this Agreement, or any part thereof, whether arising by reason of

holders pursuant to one or more registration statements under the Securities Act

delivery and performance of this Agreement, the Rights Agreement, the
Supplemental Rights Agreement, the Sales Agreement or any Ancillary Agreements
and the consummation of the transactions contemplated hereby and thereby will

event which results in the creation of any lien, charge or encumbrance upon any
assets of the Company or any Subsidiary or the suspension, revocation,

          2.14 ENVIRONMENTAL AND SAFETY LAWS.  Neither the Company nor any
Subsidiary is in violation of any applicable statute, law, or regulation

owns its property and assets free and clear of all mortgages, liens, loans and
encumbrances, except such encumbrances and liens which arise in the ordinary
course of business and do not materially impair the Company's or such
Subsidiary's ownership or use of such property or assets.  With respect to the
property and assets it leases, the Company and each Subsidiary is in compliance
with such leases and, to the best of its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances.

statement including notes) for the ten-month period ended October 26, 1996 (the

all material respects and accurately set out and describe the consolidated
financial condition and consolidated operating results of the Company and its
Subsidiaries as of the dates, and for the periods, indicated therein, subject,
with respect to its unaudited financial statements, to normal year-end audit
adjustments.  The Financial Statements have been prepared in accordance with
generally accepted accounting principles ("GAAP") except, with respect to its
unaudited financial statements, for footnotes required by GAAP.  Except as set
forth in the Financial Statements, neither the Company nor any Subsidiary has
any liabilities, contingent or otherwise, other than (i) liabilities incurred in
the ordinary course of business subsequent to October 26, 1996 which in the
aggregate do not exceed $25,000 and (ii) obligations under contracts and
commitments incurred in the ordinary course of business and not required under

indebtedness of any other person, firm or corporation (other than indebtedness

or any Subsidiary aware of any labor organization activity involving its or any
Subsidiaries' employees.  Neither the Company nor any Subsidiary is aware that

Investor to rely thereon.

Regulation D, as presently in effect.

          3.6  RESTRICTED SECURITIES.  The Investor understands that the shares
of Series C Preferred Stock it is purchasing are characterized as "restricted

without registration under the Securities Act of


                                       12.

Act covering such proposed disposition and such disposition is made in
accordance with such Registration Statement; or

               (b)(i)  The Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii) if
reasonably requested by the Company, the Investor shall have furnished the
Company with an opinion of counsel, reasonably satisfactory to the Company, that
such disposition will not require registration of such shares under the Act.  It
is agreed that the Company will not require opinions of counsel for transactions
made pursuant to Rule 144 except in unusual circumstances.

Securities may bear one or all of the following legends:

               (a)  "These securities have not been registered under the

pledged or hypothecated in the absence of a registration statement in effect
with respect to the securities under such Act or an opinion of counsel
satisfactory to the Company that such registration is not required or unless
sold pursuant to Rule 144 of such Act."

     The address of the registered office of the Corporation in the State of

                                  ARTICLE III.

     The purpose of this Corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the

                                   ARTICLE IV.

     A.   CLASSES OF STOCK.  This Corporation is authorized to issue two (2)
classes of shares, to be designated "Common" and "Preferred" and referred to
herein as the "Common Shares" or the "Preferred Shares" respectively.  The total
number of Common Shares the Corporation is authorized to issue is twenty-five
million (25,000,000). The par value is $0.01 per share.  The total number of
Preferred Shares the Corporation is authorized to issue is eighteen million
(18,000,000).  The par value is $0.01 per share.

          The Board of Directors of the Corporation may divide the Preferred
Shares into any number of series.  The Board of Directors shall fix the
designation and number of



<PAGE>

shares of each such series.  The Board of Directors may determine and alter the
rights, preferences, privileges and restrictions granted to and imposed upon any
wholly unissued series of the Preferred Shares.  The Board of Directors (within
the limits and restrictions of any resolution adopted by it, originally fixing
the number of shares of any series) may increase or decrease the number of
shares of any such series after the issue of shares of that series, but not
below the number of then outstanding shares of such series.

     B.   RIGHTS, PREFERENCES, PRIVILEGES AND RESTRICTIONS OF THE SERIES A-1
PREFERRED STOCK, SERIES A-3 PREFERRED STOCK, SERIES B PREFERRED STOCK AND SERIES
C PREFERRED STOCK.

          1.   DESIGNATION OF SERIES A-1 PREFERRED STOCK, SERIES A-3 PREFERRED
STOCK, SERIES B PREFERRED STOCK AND SERIES C PREFERRED STOCK.  Eight Million
Three Hundred Thousand (8,300,000) shares of Preferred Stock are designated
Series A-1 Preferred Stock (the "Series A-1 Preferred") with the rights,
preferences and privileges specified herein.  Five Hundred Thousand (500,000)
shares of Preferred Stock are designated Series A-3 Preferred Stock (the "Series
A-3 Preferred") with the rights, preferences and privileges specified herein.
Three Million One Hundred Thousand (3,100,000) shares of Preferred Stock are
designated Series B Preferred Stock (the "Series B Preferred") with the rights,
preferences and privileges specified herein.  Two Million (2,000,000) shares of
Preferred Stock are designated Series C Preferred Stock (the "Series C
Preferred") with the rights, preferences and privileges specified herein.  As
used in this Article IV, Section B., the term "Series A Preferred" shall refer
to the Series A-1 Preferred and the Series A-3 Preferred.  As used in this
Article IV, Section B., the term "Preferred Stock" shall refer to the Series A-1
Preferred, the Series A-3 Preferred, the Series B Preferred and the Series C
Preferred.

          2.   DIVIDEND RIGHTS OF PREFERRED STOCK.  The holders of the then
outstanding shares of Preferred Stock shall be entitled to receive dividends pro
rata, in preference to any dividend on the Common Stock of this Corporation
("Common"), at the rate of eight percent (8%) of the Original Purchase Price per
share (as defined below) per annum, whenever funds are legally available and
when and as declared by the Board of Directors.  The dividends shall be non-
cumulative.  The original purchase price of the Series A Preferred shall be
$1.325 per share (the "Series A Original Purchase Price").  The original
purchase price of the Series B Preferred shall be $4.00 per share (the "Series B
Original Purchase Price").  The original purchase price of the Series C
Preferred shall be $5.00 per share (the "Series C Original Purchase Price").  As
used in this Section 2, the term "Original Purchase Price" shall refer to the
Series A Original Purchase Price, the Series B Original Purchase Price or the
Series C Original Purchase Price, as the case may be.

          3.   LIQUIDATION PREFERENCE.

               a.   In the event of any liquidation event, either voluntary or
involuntary, the holders of the Preferred Stock shall be entitled to receive pro
rata, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of the Common by reason of their
ownership thereof, with respect to the Series C Preferred, the sum of (i) $5.00
per share for each share of Series C Preferred then


                                       -2-
<PAGE>

held by them and (ii) an amount equal to all declared but unpaid dividends on
the Series C Preferred then held by them, with respect to the Series B
Preferred, the sum of (i) $4.00 per share for each share of Series B Preferred
then held by them and (ii) an amount equal to all declared but unpaid dividends
on the Series B Preferred then held by them, and, with respect to the Series A
Preferred, the sum of (i) $1.325 per share for each share of Series A Preferred
then held by them and (ii) an amount equal to all declared but unpaid dividends
on the Series A Preferred then held by them.  If, upon the occurrence of such
event, the assets and funds thus distributed among the holders of the Preferred
Stock shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Preferred Stock in proportion to the preferential
amount each such holder would have been entitled to receive pursuant to this
Section 3 if such distribution had been sufficient to permit the full payment of
such preferential amount.

               b.   After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Section
3.a. above, the holders of the Common and Preferred Stock shall be entitled to
receive the remaining assets of the Corporation in proportion to the shares of
Common Stock then held by them and the shares of Common Stock which they have
the right to acquire upon conversion of Preferred Stock until such time as the
distributions made to the holders of the Preferred Stock (taken together with
all payments made pursuant to Section 3.a. above) equal, with respect to the
Series A Preferred, $3.975 per share for each share of Series A Preferred then
held by them, with respect to the Series B Preferred, $12.00 per share for each
share of Series B Preferred then held by them and, with respect to the Series C
Preferred, $15.00 per share for each share of Series C Preferred then held by
them.  If, upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Preferred Stock shall be insufficient to
permit the payment to such holders of the full aforesaid preferential amounts,
then the entire remaining assets and funds of the Corporation legally available
for distribution after payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Section
3.a. above shall be distributed ratably among the holders of the Common and
Preferred Stock in proportion to the preferential amount each such holder would
have been entitled to receive pursuant to this Section 3 if such distribution
had been sufficient to permit the full payment of the preferential amounts under
this Section 3.b. to the holders of the Preferred Stock.

               c.   After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled pursuant to Sections
3.a. and 3.b. above, the holders of the Common shall be entitled to receive all
remaining assets of the Corporation in proportion to the shares of Common Stock
then held by them.

               d.   For purposes of this Section 3, a liquidation, dissolution
or winding up of the Corporation shall be deemed to be occasioned by, or to
include, the Corporation's sale of all or substantially all of its assets or the
acquisition of this Corporation by another entity by means of merger or
consolidation resulting in the exchange of the outstanding shares of this
Corporation for securities or consideration issued, or caused


                                       -3-
<PAGE>

to be issued, by the acquiring Corporation or its subsidiary in which the
stockholders of the Corporation are holders of less than 50% of voting power of
the surviving corporation.

          4.   CONVERSION.  The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

               a.   OPTIONAL AND AUTOMATIC CONVERSION.  Each share of Preferred
Stock shall be convertible at the option of the holder thereof, without payment
of additional consideration, at any time after the date of issuance of such
share, at the office of the Corporation or any transfer agent for the Preferred
Stock, into such number of fully paid and nonassessable shares of Common as is
determined by dividing, with respect to the Series A Preferred, $1.325, with
respect to the Series B Preferred, $4.00, or, with respect to the Series C
Preferred, $5.00 by the Conversion Price, determined as hereinafter provided, in
effect at the time of conversion.  The price at which shares of Common shall be
deliverable upon conversion of the Series A-1 Preferred (the "Series A-1
Conversion Price") shall initially be $1.325 per share of Common.  The price at
which shares of Common shall be deliverable upon conversion of the Series A-3
Preferred (the "Series A-3 Conversion Price") shall initially be $1.325 per
share of Common.  The price at which shares of Common shall be deliverable upon
conversion of the Series B Preferred (the "Series B Conversion Price") shall
initially be $4.00 per share of Common.  The price at which shares of Common
shall be deliverable upon conversion of the Series C Preferred (the "Series C
Conversion Price") shall initially be $5.00 per share of Common.  As used in
this Section 4., the term "Conversion Price" shall refer to the Series A-1
Conversion Price, the Series A-3 Conversion Price, the Series B Conversion Price
or the Series C Conversion Price, as the case may be.  The initial Series A-1
Conversion Price, Series A-3 Conversion Price, Series B Conversion Price and
Series C Conversion Price shall be subject to adjustment as hereinafter
provided.

     Each share of Preferred Stock shall automatically be converted into shares
of Common at the then effective Conversion Price in the event of either (i) the
closing of a firm commitment underwritten public offering pursuant to an
effective registration statement under the Securities Act of 1933, as amended
(the "Act"), covering the offer and sale of Common (whether for the account of
the Corporation or for the account of one or more stockholders of the
Corporation) of the Corporation to the public in which the aggregate gross cash
proceeds to the Corporation (prior to underwriters' discounts and expenses) are
equal to or exceed $15,000,000 and the public offering price is equal to or
exceeds $5.00 per share of Common (as adjusted for any stock dividends,
combinations or splits with respect to such shares) (a "Qualified Public
Offering") or (ii) the written consent of holders of more than fifty percent
(50%) of the then outstanding shares of Preferred Stock voting together as a
single class (a "Qualifying Consent").  In the event of the automatic conversion
of the Preferred Stock upon a Qualified Public Offering, the conversion of
Preferred Stock shall be deemed to have occurred immediately prior to the
closing of such Qualified Public Offering.  In the event of the automatic
conversion of the shares of Preferred Stock upon a Qualifying Consent, the
conversion of Preferred Stock shall be deemed to have occurred on the date
specified in such Qualifying Consent.


                                       -4-
<PAGE>

               b.   MECHANICS OF CONVERSION.  No fractional shares of Common
shall be issued upon conversion of Preferred Stock.  In lieu of any fractional
shares to which the holder would otherwise be entitled, the Corporation shall
pay cash equal to such fraction multiplied by the then effective Conversion
Price.  Before any holder of Preferred Stock shall be entitled to convert the
same into full shares of Common, it shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent for the Preferred Stock, and shall give written notice to the
Corporation at such office that it elects to convert the same (except that no
such written notice of election to convert shall be necessary in the event of an
automatic conversion pursuant to Section 4.a.).  The Corporation shall, as soon
as practicable thereafter, issue and deliver at such office to such holder of
Preferred Stock a certificate or certificates, registered in such names as
specified by the holder, for the number of shares of Common to which he shall be
entitled as aforesaid and a check payable to the holder in the amount of any
cash amounts payable as the result of a conversion into fractional shares of
Common, and any declared and unpaid dividends on the converted Preferred Stock.
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 Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Common on such date (except that in the
event of an automatic conversion (i) upon a Qualified Public Offering pursuant
to Section 4.a. such conversion shall be deemed to have been made immediately
prior to the closing of the Qualified Public Offering and (ii) upon a Qualifying
Consent pursuant to Section 4.a. such conversion shall be deemed to have been
made on the date specified in such Qualifying Consent).  If the conversion is in
connection with an underwritten offering of securities registered pursuant to
the Act, the conversion may, at the option of any holder tendering Preferred
Stock for conversion, be conditioned upon the closing with the underwriter of
the sale of securities pursuant to such offering, in which event the person(s)
entitled to receive the Common issuable upon such conversion of the Preferred
Stock shall not be deemed to have converted such Preferred Stock until
immediately prior to the closing of such sale of securities.

               c.   ADJUSTMENTS TO SERIES A-1 CONVERSION PRICE, SERIES A-3
CONVERSION PRICE, SERIES B CONVERSION PRICE AND SERIES C CONVERSION PRICE FOR
DILUTIVE ISSUES.

                    (1)  SPECIAL DEFINITIONS.  For purposes of this Section 4.c.

                                       -5-
<PAGE>

of Series B Preferred was first issued and with respect to the Series C
Preferred, the date on which a share of Series C Preferred was first issued.

                         (c)  "CONVERTIBLE SECURITIES" shall mean any evidences
of indebtedness, shares (other than Common and Preferred Stock) or other
securities directly or indirectly convertible into or exchangeable for Common.

                         (d)  "ADDITIONAL SHARES OF COMMON" shall mean all
shares of Common issued (or, pursuant to Section 4.c.(3), deemed to be issued)
by the Corporation after the Original Issue Date, other than shares of Common
issued or issuable:

                              i)   upon conversion of shares of Preferred Stock
authorized herein;

                              ii)  to officers, directors or employees of, or
consultants to, the Corporation pursuant to any plan or agreement approved by
the Board of Directors;

                              iii) as a dividend or distribution on the
Preferred Stock or any event for which adjustment is made pursuant to Sections
4.d. or 4.e. hereof;

                              iv)  in connection with equipment leasing or bank
financing transactions, provided such shares are issued for other than primarily
equity financing purposes;

                              v)   pursuant to transactions involving technology
licensing, research or development activities or the distribution or manufacture
of the Corporation's products, provided that each of the forgoing transactions
is for other than primarily equity financing purposes; or

                              vi)  by way of dividend or other distribution on
shares excluded from the definition of Additional Shares of Common by the
foregoing clauses i) through v) or this clause vi) or on shares of Common so
excluded.

                    (2)  NO ADJUSTMENT OF SERIES A-1 CONVERSION PRICE,
SERIES A-3 CONVERSION PRICE, SERIES B CONVERSION PRICE OR SERIES C CONVERSION
PRICE.  No adjustment in the Series A-1 Conversion Price, Series A-3 Conversion
Price, Series B Conversion Price or Series C Conversion Price shall be made in
respect of the issuance of Additional Shares of Common unless the consideration
per share for an Additional Share of Common issued or deemed to be issued by the
Corporation is less than the Series A-1 Conversion Price, Series A-3 Conversion
Price, Series B Conversion Price or Series C Conversion Price, respectively, in
effect on the date of, and immediately prior to, the issue of such Additional
Shares.

at any time or from time to time after the Original Issue Date shall issue any
Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common issuable
upon the exercise of such Options or, in the case of Convertible Securities and
Options therefor, the conversion or exchange of such Convertible Securities,

issue or, in case such a record date shall have been fixed, as of the close of
business on such record date, provided that in any such case in which Additional
Shares of Common are deemed to be issued:

                         (a)  no further adjustment in the Series A-1 Conversion
Price, Series A-3 Conversion Price, Series B Conversion Price or Series C
Conversion Price shall be made upon the subsequent issue of Convertible
Securities or shares of Common upon the exercise of such Options or conversion
or exchange of such Convertible Securities;

                         (b)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase in the
consideration payable to the Corporation, or decreases in the number of shares
of Common issuable, upon the exercise, conversion or exchange thereof, the
Series A-1 Conversion Price, Series A-3 Conversion Price, Series B Conversion
Price and Series C Conversion Price computed upon the original issue thereof (or
upon the occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                         (c)  no readjustment pursuant to clause (b) above shall
have the effect of increasing the Series A-1 Conversion Price, Series A-3
Conversion Price, Series B Conversion Price or Series C Conversion Price to an
amount which exceeds the lower of (i) such Series A-1 Conversion Price,
Series A-3 Conversion Price, Series B Conversion Price or Series C Conversion
Price, respectively, on the original adjustment date with respect to such deemed
issuance of Additional Shares of Common, or (ii) such Series A-1 Conversion
Price, Series A-3 Conversion Price, Series B Conversion Price or Series C
Conversion Price, respectively, that would have resulted from any issuance of
Additional Shares of Common between such original adjustment date and such
readjustment date; and

                         (d)  if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any decrease in the
consideration payable to the Corporation upon the exercise, conversion or
exchange thereof, the Series A-1 Conversion Price, Series A-3 Conversion Price,
Series B Conversion Price and Series C Conversion Price computed upon the
original issue thereof (or upon the occurrence of a record date with respect
thereto), and any subsequent adjustments based thereon, shall, upon any such
decrease becoming effective, be recomputed to reflect such decrease insofar


                                       -7-
<PAGE>

as it affects such Options or the rights of conversion or exchange under such
Convertible Securities.

                    (4)  ADJUSTMENT OF CONVERSION PRICE UPON ISSUANCE OF
ADDITIONAL SHARES OF COMMON.  In the event this Corporation shall issue
Additional Shares of Common (including Additional Shares of Common deemed to be
issued pursuant to Section 4.c.(3)) without consideration or for a consideration
per share less than the Series A-1 Conversion Price, Series A-3 Conversion
Price, Series B Conversion Price or Series C Conversion Price in effect on the
date of and immediately prior to such issue, then and in such event, such Series
A-1 Conversion Price, Series A-3 Conversion Price, Series B Conversion Price or
Series C Conversion Price, respectively, shall be reduced, concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying such Series A-1 Conversion Price, Series A-3 Conversion Price,
Series B Conversion Price or Series C Conversion Price, respectively, by a
fraction, the numerator of which shall be the number of shares of Common
outstanding immediately prior to such issue plus the number of shares of Common
which the aggregate consideration received by the Corporation for the total
number of Additional Shares of Common so issued would purchase at such Series A-
1 Conversion Price, Series A-3 Conversion Price, Series B Conversion Price or
Series C Conversion Price, respectively, in effect immediately prior to such
issue; and the denominator of which shall be the number of shares of Common
outstanding immediately prior to such issue plus the number of such Additional
Shares of Common so issued; and provided further that, for the purposes of this
Section 4.c.(4): (i) no shares of Common issued or issuable upon conversion of
Preferred Stock shall be deemed to be outstanding and all such shares shall be
excluded from such calculation, (ii) all shares of Common issuable upon
conversion of outstanding Options and Convertible Securities (excluding
outstanding Preferred Stock) shall be deemed to be outstanding and all such
shares shall be included in such calculation, and (iii) except as provided in
the foregoing clauses (i) and (ii) above, immediately after any Additional
Shares of Common are deemed issued pursuant to Section 4.c.(3), such Additional
Shares of Common shall be deemed to be outstanding.  The Series A-1 Conversion
Price, Series A-3 Conversion Price, Series B Conversion Price and Series C
Conversion Price shall not be increased except as set forth in Section
4.c.(3)(b) and in Section 4.d.

                    (5)  DETERMINATION OF CONSIDERATION.  For purposes of this
Section 4.c., the consideration received by the Corporation for the issue of any
Additional Shares of Common shall be computed as follows:

                         (a)  CASH AND PROPERTY.  Such consideration shall:

                              i)   insofar as it consists of cash, be computed
at the aggregate amount of cash received by the Corporation excluding amounts
paid or payable for accrued interest or accrued dividends;

                              ii)  insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and


                                       -8-
<PAGE>

                              iii) in the event Additional Shares of Common are
issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses i) and ii) above, as
reasonably determined in good faith by the Board of Directors.

                         (b)  OPTIONS AND CONVERTIBLE SECURITIES.  The
consideration per share received by the Corporation for Additional Shares of
Common deemed to have been issued pursuant to Section 4.c.(3), relating to
Options and Convertible Securities, shall be determined by dividing:

                              i)   the total amount, if any, received or
receivable by the Corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Corporation upon the exercise of such Options or
the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such Options for Convertible
Securities and the conversion or exchange of such Convertible Securities, by

                              ii)  the maximum number of shares of Common (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

               d.   ADJUSTMENT FOR STOCK SPLITS, DIVIDENDS AND COMBINATIONS.  If
the Corporation shall at any time or from time to time effect a subdivision of
the outstanding Common, or shall issue a dividend of Common on its outstanding
Common, the Series A-1 Conversion Price, Series A-3 Conversion Price, Series B
Conversion Price and Series C Conversion Price then in effect immediately before
that subdivision or dividend shall be proportionately decreased, and conversely,
if the Corporation shall combine the outstanding shares of Common, the Series A-
1 Conversion Price, Series A-3 Conversion Price, Series B Conversion Price and
Series C Conversion Price then in effect immediately before the combination
shall be proportionately increased.  Any adjustment under this Section 4.d.
shall become effective at the close of business on the date the subdivision or
combination becomes effective or on the date on which the dividend is declared.

               e.   ADJUSTMENTS FOR OTHER DIVIDENDS AND DISTRIBUTIONS.  In the
event the Corporation at any time or from time to time shall make or issue, or
fix a record date for the determination of holders of Common entitled to receive
a dividend or other distribution payable in securities of the Corporation other
than shares of Common, then, and in each such event, provision shall be made so
that the holders of Series A-1 Preferred, Series A-3 Preferred, Series B
Preferred and Series C Preferred shall receive upon conversion thereof, in
addition to the number of shares of Common receivable thereupon, the amount of
securities of the Corporation that they would have received had their Series A-1
Preferred, Series A-3 Preferred, Series B Preferred and Series C Preferred been


                                       -9-
<PAGE>

converted into Common on the date of such event, giving effect to all
adjustments called for with respect to such securities during the period from
the date of such event to and including the conversion date.

               f.   ADJUSTMENT FOR MERGER OR REORGANIZATION.  In case of any
consolidation or merger of the Corporation with or into another corporation or
the conveyance of all or substantially all of the assets of the Corporation to
another corporation (other than a consolidation, merger or conveyance provided
for elsewhere in this Section 4 or Section 3), provisions shall be made so that
holders of shares of Series A-1 Preferred, Series A-3 Preferred, Series B
Preferred and Series C Preferred shall thereafter be convertible into the number
of shares of stock or other securities or property to which a holder of the
number of shares of Common of the Corporation deliverable upon conversion of
such Series A-1 Preferred, Series A-3 Preferred, Series B Preferred and Series C
Preferred would have been entitled upon such consolidation, merger or
conveyance; and, in any case, appropriate adjustment (as reasonably determined
in good faith by the Board of Directors) shall be made in the application of the
provisions herein set forth with respect to the rights and interest thereafter
of the holders of the Series A-1 Preferred, Series A-3 Preferred, Series B
Preferred and Series C Preferred, to the end that the provisions set forth
herein (including provisions with respect to changes in and other adjustments of
the Conversion Price) shall thereafter be applicable, as nearly as reasonably
may be, in relation to any shares of stock or other property thereafter
deliverable upon the conversion of the Series A-1 Preferred, Series A-3
Preferred, Series B Preferred and Series C Preferred.

               g.   ADJUSTMENT FOR RECLASSIFICATION, EXCHANGE AND SUBSTITUTION.
If the Common issuable upon the conversion of the Series A-1 Preferred,
Series A-3 Preferred, Series B Preferred and Series C Preferred shall be changed
into the same or different number of shares of any class or series of stock,
whether by capital reorganization, reclassification or otherwise (other than as
set forth above in this Section 4), then and in each such event the holder of
each share of Series A-1 Preferred, Series A-3 Preferred, Series B Preferred and
Series C Preferred shall have the right thereafter to convert such share into
the kind and amount of shares of stock and other securities and property
receivable upon such reorganization, reclassification or other change by holders
of the number of shares of Common into which such shares of Series A-1
Preferred, Series A-3 Preferred, Series B Preferred and Series C Preferred might
have been converted immediately prior to such reorganization, reclassification
or change, all subject to further adjustment as provided herein.

               h.   NO IMPAIRMENT.  The Corporation will not, by amendment of
this Amended and Restated Certificate 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 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-1 Preferred, Preferred, Series
A-3 Preferred, Series B Preferred and Series C Preferred against impairment.


                                      -10-
<PAGE>

               i.   CERTIFICATE AS TO ADJUSTMENTS.  Upon the occurrence of each
adjustment or readjustment of the Series A-1 Conversion Price, Series A-3
Conversion Price, Series B Conversion Price or Series C Conversion Price
pursuant to this Section 4, the Corporation at its expense shall promptly
compute such adjustments or readjustments in accordance with the terms hereof
and furnish to each holder of any such Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based.  The Corporation shall, upon the
written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Series A-1 Conversion Price, Series A-3
Conversion Price, Series B Conversion Price or Series C Conversion Price at the
time in effect, and (iii) the number of shares of Common and the amount, if any,
of other property which at the time would be received upon the conversion of
such holder's shares.

               j.   NOTICES OF RECORD DATE.  In the event of any taking by the
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 which is the same as cash dividends paid in
previous quarters) or other distribution, the Corporation shall mail to each
holder of Preferred Stock at least ten (10) 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 or distribution.  Each such written notice
shall be given by first class mail, postage prepaid, addressed to the holders of
Preferred Stock at the address for each such holder as shown on the books of
this Corporation.

               k.   COMMON STOCK RESERVED.  The Corporation shall at all times
reserve and keep available out of its authorized but unissued shares of Common,
solely for the purpose of effecting the conversion of the shares of Preferred
Stock, such number of shares of Common as shall from time to time be sufficient
to effect the conversion of all outstanding shares of Preferred Stock, and if at
any time the number of authorized but unissued shares of Common shall not be
sufficient to effect the conversion of all then outstanding shares of Preferred
Stock, the Corporation shall take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares of
Common to such number of shares as shall be sufficient for such purpose.

          5.   VOTING RIGHTS.  Each holder of shares of Series A-1 Preferred
shall be entitled to the number of votes equal to the number of shares of Common
into which such shares of Series A-1 Preferred could be converted on the record
date for the vote or the date of the solicitation of any written consent of
stockholders and shall have voting rights and powers equal to the voting rights
and powers of the Common.  The Series A-3 Preferred shall be non-voting
Preferred, except as otherwise required by law.  Each holder of shares of Series
B Preferred shall be entitled to the number of votes equal to the number of
shares of Common into which such shares of Series B Preferred could be converted
on the record date for the vote or the date of the solicitation of any written
consent of stockholders and shall have voting rights and powers equal to the
voting rights and powers of the Common.  Each holder of shares of Series C
Preferred shall be entitled to the number of votes equal to the number of shares
of Common into which such shares of Series C Preferred could be


                                      -11-
<PAGE>

converted on the record date for the vote or the date of the solicitation of any
written consent of stockholders and shall have voting rights and powers equal to
the voting rights and powers of the Common.  Each holder of Common shall be
entitled to one vote per share of Common held by such holder.  The holder of
each share of Series A-1 Preferred, Series B Preferred and Series C Preferred
shall be entitled to notice of any stockholders' meeting in accordance with the
Bylaws of the Corporation and shall vote with holders of the Common upon all
matters submitted to a vote of stockholders, except those matters required by
law to be submitted to a class vote and except as provided in Section 6 below.
Fractional votes by the holders of Series A-1 Preferred, Series B Preferred and
Series C Preferred shall not, however, be permitted and any fractional voting
rights resulting from the above formula shall be rounded to the nearest whole
number.

          6.   RESTRICTIONS AND LIMITS.

               a.   So long as fifty percent (50%) or more of the originally
issued shares of Series A-1 Preferred, Series B Preferred and Series C Preferred
shall be outstanding, the Corporation shall not, without first obtaining the
affirmative vote or written consent of the holders of not less than sixty-six
and two-thirds percent (66-2/3%) of the then outstanding shares of Series A-1
Preferred, Series B Preferred and Series C Preferred, voting as a class:

                    (1)  amend or repeal any provision of, or add any provision
to, the Corporation's Amended and Restated Certificate of Incorporation or
Bylaws if such action would adversely alter or change the preferences, rights,
privileges or powers of, or the restrictions provided for the benefit of the
Series A-1 Preferred, Series B Preferred or Series C Preferred;

                    (2)  create any new series or class of stock having any
rights, preferences or privileges senior to or on a parity with any such rights,
preferences or privileges of the Series A-1 Preferred, Series B Preferred or
Series C Preferred;

                    (3)  increase or decrease the authorized number of shares of
Series A Preferred, Series B Preferred, Series C Preferred or Preferred;

                    (4)  pay any dividend on, or redeem, repurchase or otherwise
acquire any shares of, the Common or Preferred (other than (i) any repurchases
of shares of Common held by an employee of the Corporation upon termination of
employment, and (ii) as approved by the Board of Directors);

                    (5)  merge into or consolidate with any other corporation or
entity (other than any transaction in which the Corporation's stockholders own a
majority of the securities of the surviving corporation) or sell all or
substantially all of the assets of the Corporation;

                    (6)  amend, or take any action intended to circumvent, the
provisions of this Section 6.


                                      -12-
<PAGE>

          7.   STATUS OF CONVERTED STOCK.  In the event any shares of Preferred
Stock shall be converted pursuant to Section 4 hereof, the shares so converted
shall be cancelled and shall not be issuable by the Corporation.  The
Certificate of Incorporation of this Corporation shall be appropriately amended
to effect the corresponding reduction in the Corporation's authorized capital
stock.

          8.   RESIDUAL RIGHTS.  All rights accruing to the outstanding shares
of the Corporation not otherwise expressly provided for in this Amended and
Restated Certificate of Incorporation shall be vested in the Common.

          9.   REPURCHASE OF SHARES.  In connection with repurchases by this
Corporation of its Common Stock pursuant to agreements with certain of the
holders thereof approved by this Corporation's Board of Directors, each holder
of Preferred Stock shall be deemed to have waived the application, in whole or
in part, of any provisions of the Delaware General Corporation Law or any
applicable law of any other state which might limit or prevent or prohibit such
repurchases.

                                   ARTICLE V.

     A.   EXCULPATION.

          1.   CALIFORNIA.  The liability of each and every director of this
Corporation for monetary damages shall be eliminated to the fullest extent
permissible under California law.

          2.   DELAWARE.  A director of the Corporation shall not be personally
liable to the Corporation or its stockholders for monetary damages for breach of
fiduciary duty as a director, except for liability (i) for any breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of the Delaware General
Corporation Law or (iv) for any transaction from which the director derived any
improper personal benefit.  If the Delaware General Corporation Law is hereafter
amended to further reduce or to authorize, with the approval of the
Corporation's stockholders, further reductions in the liability of the
Corporation's directors for breach of fiduciary duty, then a director of the
Corporation shall not be liable for any such breach to the fullest extent
permitted by the Delaware General Corporation Law as so amended.

          3.   CONSISTENCY.  In the event of any inconsistency between Sections
1 and 2 of this subsection A, the controlling Section, as to any particular
issue with regard to any particular matter, shall be the one which provides to
the director in question the greatest protection from liability.

     B.   INDEMNIFICATION.

directors and officers of this Corporation to the fullest extent permissible

of expenses to) agents (as defined in Section 317 of the California Corporations
Code) through bylaw provisions, agreements with agents, vote of stockholders or
disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 317 of the California Corporations
Code, subject only to applicable limits set forth in Section 204 of the
California Corporations Code, with respect to actions for breach of duty to the
Corporation and its stockholders.

          2.   DELAWARE.  To the extent permitted by applicable law, this

expenses to) such agents (and any other persons to which Delaware law permits
this Corporation to provide indemnification) through bylaw provisions,
agreements with such agents or other persons, vote of stockholders or
disinterested directors or otherwise, in excess of the indemnification and
advancement otherwise permitted by Section 145 of the Delaware General
Corporation Law, subject only to limits created by applicable Delaware law
(statutory or non-statutory), with respect to actions for breach of duty to the
Corporation, its stockholders, and others.

          3.   CONSISTENCY.  In the event of any inconsistency between Sections
1 and 2 of this subsection B, the controlling Section, as to any particular
issue with regard to any particular matter, shall be the one which authorizes
for the benefit of the agent or other person in question the provision of the
fullest, promptest, most certain or otherwise most favorable indemnification
and/or advancement.

     C.   EFFECT OF REPEAL OR MODIFICATION.  Any repeal or modification of any
of the foregoing provisions of this Article V shall not adversely affect any
right or protection of a director, officer, agent or other person existing at
the time of, or increase the liability of any director of the Corporation with
respect to any acts or omissions of such director occurring prior to, such
repeal or modification.

                                   ARTICLE VI.

     The Corporation shall have perpetual existence.


                                  ARTICLE VII.

     Except as otherwise provided in this Certificate of Incorporation, in
furtherance and not in limitation of the powers conferred by statute, the Board
of Directors is expressly authorized to make, repeal, alter, amend and rescind
any or all of the Bylaws of the Corporation.


                                  ARTICLE VIII.

     The Company has qualified or applied to qualify to do business in

otherwise, provided that if such closing occurs prior to the closing of the
Company's initial public offering, the Warrant Price (subject to adjustment as
provided herein) shall be $5.00 per share ($6.67 after the Reverse Split).

     This Warrant and any Warrant subsequently issued upon exchange or transfer
hereof are hereinafter collectively called the "Warrant."

     Section 1.  EXERCISE OF WARRANT.  Subject to the provisions of the first
paragraph of this Warrant, the rights represented by this Warrant may be
exercised by the Holder,

<PAGE>

in whole or in part (but not as to fractional shares) at any time or from time
to time during the Exercise Period by the completion of the purchase form
attached hereto and by the surrender of this Warrant (properly endorsed) at the
office of the Corporation as it may designate by notice in writing to the Holder
hereof at the address of the Holder appearing on the books of the Corporation,
and by payment to the Corporation of the Warrant Price in cash or by certified
or official bank check, or alternatively in accordance with Section 2 below, for
each share being purchased.  In the event of any exercise of the rights
represented by this Warrant, a certificate or certificates for the shares of
Common Stock so purchased, registered in the name of the Holder, or its nominee
or other party designated in the purchase form by the Holder hereof, shall be
delivered to the Holder within thirty (30) business days after the date in which
the rights represented by this Warrant shall have been so exercised; and, unless
this Warrant has expired or has been exercised in full, a new Warrant
representing the number of shares (except a remaining fractional share), if any,
with respect to which this Warrant shall not then have been exercised shall also
be issued to the Holder within such time.  The person in whose name any
certificate for shares of Common Stock is issued upon exercise of this Warrant
shall for all purposes be deemed to have become the holder of record of such
shares on the date on which this Warrant was surrendered and payment of the
Warrant Price, except that, if the date of such surrender and payment is a date
on which the stock transfer books of the Corporation are closed, such person
shall be deemed to have become the holder of such shares at the close of
business on the next succeeding date on which the stock transfer books are open.
No fractional shares shall be issued upon exercise of this Warrant and no
payment or adjustment shall be made upon any exercise on account of any cash
dividends on the Common Stock issued upon such exercise.  If any fractional
interest in a share of Common Stock would, except for the provision of this
Section 1, be delivered upon such exercise, the Corporation, in lieu of delivery
of a fractional share thereof, shall pay to the Holder an amount in cash equal
to the current market price of such fractional share as determined in good faith
by the Board of Directors of the Corporation (the "Board").

     Section 2.  NET ISSUANCE.

          (a)  RIGHT TO CONVERT.  In addition to and without limiting the rights
of the Holder under the terms of this Warrant, the Holder shall have the right
to convert this Warrant or any portion thereof (the "Conversion Right") into
shares of Common Stock as provided in this Section 2 at any time or from time to
time during the Exercise Period.  Upon exercise of the Conversion Right with
respect to a particular number of shares subject to the Warrant (the "Converted
Warrant Shares"), the Corporation shall deliver to the Holder (without payment
by the Holder of any exercise price or any cash or other consideration) that
number of shares of fully paid and nonassessable Common Stock computed using the
following formula:


                                       -2-

<PAGE>

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

     Where     X =  the number of shares of Common Stock to be delivered to the
                    holder

               Y =  the number of Converted Warrant Shares

               A =  the fair market value of one share of the Corporation's
                    Common Stock on the Conversion Date (as defined below)

               B =  the per share exercise price of the Warrant (as adjusted to
                    the Conversion Date)

The Conversion Right may only be exercised with respect to a whole number of
shares subject to the Warrant.  No fractional shares shall be issuable upon
exercise of the Conversion Right, and if the number of shares to be issued
determined in accordance with the foregoing formula is other than a whole
number, the Corporation shall pay to the Holder an amount in cash equal to the
fair market value of the resulting fractional share on the Conversion Date (as
defined below).  Shares issued pursuant to the Conversion Right shall be treated
as if they were issued upon the exercise of the Warrant.

          (b)  METHOD OF EXERCISE.  The Conversion Right may be exercised by the
Holder by the surrender of the Warrant at the principal office of the
Corporation together with a written statement specifying that the Holder thereby
intends to exercise the Conversion Right and indicating the total number of
shares under the Warrant that the Holder is exercising through the Conversion
Right.  Such conversion shall be effective upon receipt by the Corporation of
the Warrant together with the aforesaid written statement, or on such later date
as is specified therein (the "Conversion Date").  Certificates for the shares
issuable upon exercise of the Conversion Right and, if applicable, a new warrant
evidencing the balance of the shares remaining subject to the Warrant, shall be
issued as of the Conversion Date and shall be delivered to the Holder promptly
following the Conversion Date.

          (c)  DETERMINATION OF FAIR MARKET VALUE.  For purposes of this Section
2, fair market value of a share of Common Stock on the Conversion Date shall
mean:

                (i)  If traded on a stock exchange, the fair market value of the
Common Stock shall be deemed to be the average of the closing selling prices of
the Common Stock on the stock exchange determined by the Board to be the primary
market for the Common Stock over the ten (10) trading day period (or such
shorter period immediately following the closing of an initial public offering)
ending on the date prior to the Conversion Date, as such prices are officially
quoted in the composite tape of transactions on such exchange;


                                       -3-

<PAGE>

               (ii)  If traded over-the-counter, the fair market value of the
Common Stock shall be deemed to be the average of the closing bid prices (or, if
such information is available, the closing selling prices) of the Common Stock
over the ten (10) trading day period (or such shorter period immediately
following the closing of an initial public offering) ending on the date prior to
the Conversion Date, as such prices are reported by the National Association of
Securities Dealers through its NASDAQ system or any successor system; and

               (iii) If there is no public market for the Common Stock, then the
fair market value shall be determined by mutual agreement of the holder of the
Warrant and the Corporation, and if the Holder and the Corporation are unable to
so agree, by a valuation consultant or an investment banking firm of national
reputation selected by the Corporation and reasonably acceptable to the holder
of the Warrant.


     Section 3.  STOCK SPLITS, CONSOLIDATION, MERGER AND SALE.  In the event
that before the issuance of the shares of Common Stock into which this Warrant
may be exercised the outstanding shares of Common Stock of the Corporation shall
be split, combined or consolidated, by dividend, reclassification or otherwise,
into a greater or lesser number of shares of Common Stock, the Warrant Price in
effect immediately prior to such combination or consolidation and the number of
shares purchasable under this Warrant shall, concurrently with the effectiveness
of such combination or consolidation, be proportionately adjusted.  If there
shall be effected any consolidation or merger of the Corporation with another
corporation, or a sale of all or substantially all of the Corporation's assets
to another corporation, and if the holders of Common Stock shall be entitled
pursuant to the terms of any such transaction to receive stock, securities or
assets with respect to or in exchange for Common Stock, then, as a condition of
such consolidation, merger or sale, lawful and adequate provisions shall be made
whereby the Holder of this Warrant shall thereafter have the right to receive,
upon the basis and upon the terms and conditions specified herein and in lieu of
the shares of Common Stock immediately theretofore receivable upon the exercise
of such Warrant, such shares of stock, securities or assets as may be issuable
or payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of shares of such Common Stock immediately
theretofore so receivable had such consolidation, merger or sale not taken
place, and in any such case appropriate provisions shall be made with respect to
the rights and interests of the Holder to the end that the provisions hereof
shall thereafter be applicable, as nearly as may be, in relation to any shares
of stock, securities or assets thereafter deliverable upon the exercise of this
Warrant.

          (a) STOCK TO BE RESERVED.  The Corporation will at all times reserve
and keep available out of its authorized Common Stock, solely for the purpose of
issue upon the exercise of this Warrant as herein provided, such number of
shares of Common Stock as shall then be issuable upon the exercise of this
Warrant.  The Corporation shall from time to time in accordance with applicable
law increase the authorized amount of its Common Stock if at any time the number
of shares of Common Stock remaining


                                       -4-

<PAGE>

unissued and available for issuance shall not be sufficient to permit exercise
of this Warrant.  The Corporation covenants that all shares of Common Stock
which shall be so issued shall be duly and validly issued and fully paid and
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, and, without limiting the generality of the foregoing, the
Corporation will take all such action as may be necessary to assure that all
such shares of Common Stock may be so issued without violation of any applicable
law or regulation, or of any requirements of any national securities exchange
upon which shares of capital stock of the Corporation may be listed.

          (b) ISSUE TAX.  The issuance of certificates for shares of Common
Stock upon exercise of this Warrant shall be made without charge to the Holder
of this Warrant for any issuance tax in respect thereof provided that the
Corporation shall not be required to pay any tax which may be payable in respect
of any transfer involved in the issuance and delivery of any certificate in a
name other than that of the Holder of this Warrant.

          (c) CLOSING OF BOOKS.  The Corporation will at no time close its
transfer books against the transfer of the shares of Common Stock issued or
issuable upon the exercise of this Warrant in any manner which interferes with
the timely exercise of this Warrant.

     Section 4.  NOTICES OF RECORD DATES.  In the event of:

          (a)  any taking by the 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 or other distribution (other than cash
dividends out of earned surplus), or any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, or

          (b) any capital reorganization of the Corporation, any
reclassification or recapitalization of the capital stock of the Corporation or
any transfer of all or substantially all the assets of the Corporation to or
consolidation or merger of the Corporation with or into any other corporation,
or

          (c) any voluntary or involuntary dissolution, liquidation or
winding-up of the Corporation,

then and in each such event the Corporation will give notice to the Holder of
this Warrant specifying (i) the date on which any such record is to be taken for
the purpose of such dividend, distribution or right and stating the amount and
character of such dividend, distribution or right, and (ii) the date on which
any such reorganization, reclassification, recapitalization, transfer,
consolidation, merger, dissolution, liquidation or winding-up is to take place,
and the time, if any is to be fixed, as of which the holders of record of Common
Stock will be entitled to exchange their shares of Common Stock for securities
or other property deliverable upon such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up.


                                       -5-

<PAGE>

Such notice shall be given at least ten (10) days and not more than ninety (90)
days prior to the date therein specified, and such notice shall state that the
action in question or the record date is subject to the effectiveness of a
registration statement under the Securities Act of 1933, as amended (the
"Securities Act") or to a favorable vote of stockholders, if either is required.

     Section 5.  NO STOCKHOLDER RIGHTS OR LIABILITIES.  This Warrant shall not
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Corporation.  No provision hereof, in the absence of affirmative action
by the Holder hereof to purchase shares of Common Stock, and no mere enumeration
hereon of the rights or privileges of the Holder hereof, shall give rise to any
liability of such Holder for the Warrant Price or as a stockholder of the
Corporation, whether such liability is asserted by the Corporation or by
creditors of the Corporation.

     Section 6.  REPRESENTATIONS OF HOLDER.

     The Holder hereby represents and acknowledges to the Corporation that:

          (a)  this Warrant, the Common Stock issuable upon exercise of this
Warrant and any securities issued with respect to any of them by way of a stock
dividend or stock split or in connection with a recapitalization, merger,
consolidation or other reorganization will be "restricted securities" as such
term is used in the rules and regulations under the Securities Act and that such
securities have not been and may not be registered under the Securities Act or
any state securities law, and that such securities must be held indefinitely
unless registration is effected or transfer can be made pursuant to appropriate
exemptions;

          (b)  the Holder has read, and fully understands, the terms of this
Warrant set forth on its face and the attachments hereto, including the
restrictions on transfer contained herein;

          (c)  the Holder has either a pre-existing personal or business
relationship with the Corporation or one of its officers, directors or
controlling persons;

          (d)  the Holder is purchasing for investment for its own account and
not with a view to or for sale in connection with any distribution of this
Warrant or the Common Stock of the Corporation issuable upon exercise of this
Warrant and it has no intention of selling such securities in a public
distribution in violation of the federal securities laws or any applicable state
securities laws; provided that nothing contained herein will prevent Holder from
transferring such securities in compliance with the terms of this Warrant and
the applicable federal and state securities laws;

          (e)  the Holder is an "accredited investor" within the meaning of
paragraph (a) of Rule 501 of Regulation D promulgated by the Securities and
Exchange Commission and an "excluded purchaser" within the meaning of Section
25102(f) of the California Corporate Securities Law of 1968; and


                                       -6-

<PAGE>

          (f) the Corporation may affix the following legend (in addition to any
other legend(s), if any, required by applicable state corporate and/or
securities laws) to certificates for shares of Common Stock (or other
securities) issued upon exercise of this Warrant ("Warrant Shares"):

          "These securities have not been registered under the
          Securities Act of 1933, or any state securities laws.  They
          may not be sold, offered for sale, pledged or hypothecated
          in the absence of a registration statement in effect with
          respect to the securities under all applicable federal and
          state securities laws or an opinion of counsel satisfactory
          to the Corporation that such registration is not required or
          unless sold pursuant to Rule 144 of such Act."

     Section 7.  NOTICE OF PROPOSED TRANSFERS.  This Warrant may not be
transferred, in whole or in part, until December 31, 1999; provided, however,
that this Warrant may be transferred in whole to any successor to substantially
all of the business of the original Holder.  The Holder of this Warrant, by
acceptance hereof, agrees to comply in all respects with the provisions of this
Section 7.  Prior to any proposed transfer of this Warrant or any Warrant
Shares, unless (i) pursuant to and in compliance with Rule 144 or (ii) there is
in effect a registration statement under the Securities Act covering the
proposed transfer, the Holder of such securities shall give written notice to
the Corporation of such Holder's intention to effect such transfer.  Each such
notice shall describe the manner and circumstances of the proposed transfer in
sufficient detail, and shall be accompanied by either (i) a written opinion of
legal counsel who shall be reasonably satisfactory to the Corporation addressed
to the Corporation and reasonably satisfactory in form and substance to the
Corporation's counsel, to the effect that the proposed transfer of the Warrant
and/or Warrant Shares may be effected without registration under the Securities
Act, or (ii) a "no action" letter from the U.S. Securities and Exchange
Commission (the "Commission") to the effect that the transfer of such securities
without registration will not result in a recommendation by the staff of the
Commission that enforcement action be taken with respect thereto, whereupon the
Holder of such securities shall be entitled to transfer such securities in
accordance with the terms of the notice delivered by the Holder to the
Corporation.  Each new certificate evidencing the Warrant and/or Warrant Shares
so transferred shall bear the appropriate restrictive legends set forth in
Section 6(f) above, except that such certificate shall not bear such restrictive
legend if, in the opinion of counsel for the Corporation, such legend is not
required in order to establish or assist in compliance with any provisions of
the Securities Act or any applicable state securities laws.

     Section 8.  LOST, STOLEN, MUTILATED OR DESTROYED WARRANT.  If this Warrant
is lost, stolen, mutilated or destroyed, the Corporation may, on such terms as
to indemnity or otherwise as it may in its discretion reasonably impose (which
shall, in the case of a mutilated Warrant, include the surrender thereof), issue
a new Warrant of like denomination and tenor as the Warrant so lost, stolen,
mutilated or destroyed.  Any such new Warrant shall constitute an original
contractual obligation of the Corporation,


                                       -7-

<PAGE>

whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall
be at any time enforceable by anyone.

     Section 9.  PRESENTMENT.  Prior to due presentment of this Warrant together
with a completed assignment form attached hereto for registration of transfer,
the Corporation may deem and treat the Holder as the absolute owner of the
Warrant, notwithstanding any notation of ownership or other writing thereon, for
the purpose of any exercise thereof and for all other purposes, and the
Corporation shall not be affected by any notice to the contrary.

     Section 10.  NOTICE.  Notice or demand pursuant to this Warrant shall be
sufficiently given or made, if sent by first-class mail, postage prepaid,
addressed, if to the Holder of this Warrant, to the Holder at its last known
address as it shall appear in the records of the Corporation, and if to the
Corporation, at 5451 Avenida Encinas, Suite A, Carlsbad, California 92008,
Attention:  Secretary.  The Corporation may alter the address to which
communications are to be sent by giving notice of such change of address in
conformity with the provisions of this Section 10 for the giving of notice.

     Section 11.  GOVERNING LAW.  The validity, interpretation and performance
of this Warrant shall be governed by the laws of the State of California without
regard to principles of conflicts of laws.

     Section 12.  SUCCESSORS, ASSIGNS.  Subject to the restrictions on transfer
by Holder set forth in Section 7 hereof, all the terms and provisions of the
Warrant shall be binding upon and inure to the benefit of and be enforceable by
the respective successors and assigns of the parties hereto.

     Section 13.  AMENDMENT.  This Warrant may be modified, amended or
terminated by a writing signed by the Corporation and the Holder.

     Section 14.  SEVERABILITY.  Should any part but not the whole of this
Warrant for any reason be declared invalid, such decision shall not affect the
validity of any remaining portion, which remaining portion shall remain in force
and effect as if this Warrant had been executed with the invalid portion thereof
eliminated, and it is hereby declared the intention of the parties hereto that
they would have executed the remaining portion of this Warrant without including
therein any such part which may, for any reason, be hereafter declared invalid.

     Section 15.    INVESTOR RIGHTS.  The Company agrees to amend its Amended
and Restated Investors' Rights Agreement dated November 27, 1996 (the
"Investors' Rights Agreement") to include the Converted Warrant Shares within
the definition of Registrable Securities in such agreement.

             Authorization ("RGA") number.  ASTC shall provide the RGA number to
             DISTRIBUTOR within seven (7) days of receipt of the request unless,
             in ASTC's reasonable determination, return of the ASTC Products is
             inappropriate or unnecessary; the grounds for which shall be
             provided in writing to DISTRIBUTOR within such seven day period.

     7.4.    Within seven (7) days of receipt of the RGA number DISTRIBUTOR

             the rejected ASTC Products.  ASTC shall pay the shipping charges
             back to DISTRIBUTOR for properly rejected products; otherwise

             given, ASTC shall levy a return charge amounting to twenty percent
             (20%) of DISTRIBUTOR'S purchase price for such ASTC Product, and
             shall credit the balance of the purchase price to DISTRIBUTOR's
             account within forty five (45) days upon receipt of such returned
             ASTC Product.  DISTRIBUTOR shall be responsible for all shipping

             13.2.1.     by the occurrence of an economic contingency the non-
                         occurrence of which was a basic assumption on which
                         this Agreement was made, or

             13.2.2.     by compliance in good faith with any applicable foreign
                         or domestic governmental law, regulation, or order,
                         then this Agreement shall terminate immediately.  For
                         purposes of this Agreement, currency devaluation,
                         currency restrictions, currency and exchange controls,
                         and other monetary controls, restrictions and
                         restraints shall not be considered to render the
                         performance of this Agreement by DISTRIBUTOR
                         commercially impracticable or otherwise be considered
                         force majeure with respect to DISTRIBUTOR.

14.  CHANGES AND ADDITIONS TO AGREEMENT:  The International Distribution
             Agreement, including these Standard Terms and conditions
             incorporated therein, constitutes the entire and final agreement
             between the parties and supersedes all prior agreements and
             understandings, oral or written, all of which are deemed to have
             been merged herein.  No modification, assignment, or any future
             representation, promise, or agreement in connection with the
             subject matter of this International Distribution Agreement shall
             be binding on ASTC and DISTRIBUTOR unless made in writing and
             signed by a duly authorized officer of each.

15.  GOVERNING LAW AND JURISDICTION:

     15.1.   This Distribution Agreement shall be deemed to have been executed

             America, and all

                                      -18-

                                    EXHIBIT A

             questions arising out of or under this Agreement shall be governed
             by the laws of the Commonwealth of Massachusetts and the United
             States of America.

     15.2.   Any and all claims, actions, and lawsuits seeking damages for
             personal injuries or death resulting from the use of an ASTC
             Product shall be subject to, and governed by the laws of the
             jurisdiction where the injury or death is alleged to have occurred.
             In case of any litigation arising out of any dispute between the
             parties concerning the interpretation or the compliance with this
             Agreement the parties hereby expressly declare to accept the
             jurisdiction of the Massachusetts Courts.  Notwithstanding the
             foregoing however, ASTC shall be entitled at its discretion to seek
             relief in a court of competent jurisdiction in the district in
             which DISTRIBUTOR is domiciled.

16.  PROPRIETARY INFORMATION:

     16.1.   DISTRIBUTOR acknowledges that it has access to valuable proprietary
             information including but not limited to technical data and
             customer and marketing information, all of which are the property
             of ASTC, have been maintained confidential and are used in the
             course of ASTC business.

     16.2.   DISTRIBUTOR shall not, either during the term of this Agreement or
             thereafter, disclose such ASTC proprietary information to anyone
             other than those of its employees having a need to know and shall
             refrain from use of such information other than in the performance
             of this Agreement.  In addition, DISTRIBUTOR shall take all
             reasonable precautions to protect the value and confidentiality of
             such information to ASTC.  All records, files, notes, drawings,
             prints, samples, advertising material and the like relating to the
             business, products, or projects of ASTC and all copies made from
             such documents shall remain the sole and exclusive property of ASTC
             and shall be returned to ASTC immediately upon written request by
             ASTC.

     16.3.   Neither party shall be obligated or required to maintain in
             confidence any information with respect to which it can demonstrate
             with written records

             16.3.1.     is in the public domain or known to the receiving party
                         prior to disclosure by the disclosing party; or

             16.3.2.     becomes known to the public after disclosure by the
                         disclosing party, other than through breach of this
                         Agreement; or

                                      -19-

<PAGE>

                                    EXHIBIT A

             16.3.3.     becomes known to the receiving party from a source
                         other than the disclosing party without breach of any
                         obligation of confidence; or

             16.3.4.     is or has been furnished to a third party by the
                         disclosing party without restriction on the third
                         party's right to disclose such information.

17.  GOVERNMENT REGULATIONS:

     17.1.   DISTRIBUTOR agrees that it will secure and maintain any and all
             required approvals by any government other than the United States
             of America and all required product and public health registrations
             for the implementation, execution and performance of the
             Distribution Agreement.

     17.2.   Upon any expiration, cancellation, or termination of this
             Agreement, such approvals and registrations shall be transferred
             and delivered to, and shall inure to the benefit of ASTC, to the
             extent that this is permissible under applicable law, to ASTC other
             than lawfully imposed transfer fees.  The cost of said transfer
             will not exceed $10,000.  DISTRIBUTOR shall obtain all necessary
             documents or licenses and shall comply with all applicable laws and
             regulations, including, if required, registration of this
             International Distribution Agreement.

     17.3.   DISTRIBUTOR shall notify ASTC of all permits, approvals and
             registrations obtained by it, and shall further notify ASTC of any
             other regulatory requirements with respect to DISTRIBUTOR's sale,
             distribution, or service of ASTC Products within the Territory, as
             such regulatory requirements may be in effect from time to time.

     17.4.   DISTRIBUTOR agrees that it shall not allow either the products
             supplied to it by ASTC,  ASTC's trademarks, any proprietary data of
             ASTC, or any direct product of such data, to be knowingly made
             available, either directly or indirectly, or in any way to be
             knowingly given, transferred, sold or re-exported to any country in
             violation of its laws and export control regulations or applicable
             laws of any country (or the European Economic Community).

     17.5.   United States laws and export control regulations governing the
             exportability of technical data and products to nations are subject
             to change.  If any country included within DISTRIBUTOR's Primary
             Area of Responsibility shall, at the time of execution of the
             Distribution Agreement, or at any time during the life of the
             Distribution Agreement,

                                      -20-

<PAGE>

                                    EXHIBIT A

             be placed in an excluded category by the United States government
             for the receipt of either technical data or the manufacture or sale
             of products of a type such as the ASTC Products, then the
             DISTRIBUTOR agrees that it shall take all appropriate and necessary
             actions so as to cease business activities, selling, and promoting
             such ASTC Products in and within such excluded country.

18.  UNFAIR COMPETITION AND PATENT INFRINGEMENT:

     18.1.   DISTRIBUTOR shall promptly advise ASTC of any infringement or
             potential infringement by third parties of which DISTRIBUTOR
             becomes aware, or of any issued patents relating to the ASTC
             Products supplied by ASTC under this Agreement.  ASTC shall have
             the right, but not the obligation, to sue alleged infringers.

     18.2.   If suit is brought by ASTC, ASTC shall control the prosecution
             thereof and be entitled to retain any amounts recovered in full by
             reason of such infringement.  DISTRIBUTOR agrees to cooperate with
             and assist ASTC in any such suit.  ASTC shall reimburse distributor
             for reasonable costs related to such assistance if such costs were
             incurred at the request of ASTC.  ASTC shall have the exclusive
             right to negotiate and approve any settlement of such suits.

     18.3.   In the event that DISTRIBUTOR joins ASTC by mutual agreement in
             litigation relating to such infringement, DISTRIBUTOR shall bear an
             agreed proportion of the legal costs.  Should any damages or costs
             in such litigation be awarded to ASTC and DISTRIBUTOR, DISTRIBUTOR
             shall be entitled to recover the same proportion thereof as its
             contribution to expenses.

     18.4.   ASTC represents that it has no knowledge of any patent rights in
             the Territory that would be infringed by use or sale of ASTC
             products therein, or by use of ASTC's proprietary information.
             ASTC does not warrant that the manufacture, use or sale of any of
             its products, or utilization of any of its proprietary information
             is free of liability for infringement or charges of infringement of
             patent rights owned by third parties.  In the event that ASTC is
             enjoined from making and selling and/or DISTRIBUTOR is enjoined
             from selling ASTC Products as a result of charges of infringement
             of patent rights, such injunction shall not constitute a breach of
             this Agreement.

19.  SUCCESSORS AND ASSIGNS:  This Agreement shall be binding upon and inure to
             the benefit of the parties hereto and their respective successors

                                      -21-

<PAGE>

                                    EXHIBIT A

             and assigns, provided, however, that neither party shall have the
             right to assign or otherwise transfer its rights hereunder without
             the express prior written consent of the other party.  Any other
             assignment without such consent shall be null and void.  ASTC shall
             have the right at its sole option to terminate this International
             Distribution Agreement upon the making of any such purported
             assignment by DISTRIBUTOR.  Provided, however, by its execution of
             this Agreement, DISTRIBUTOR expressly consents to the assignment by
             ASTC of this Agreement to a successor to ASTC's business, in the
             event of any such assignment by ASTC.

20.  MISCELLANEOUS PROVISIONS:

     20.1.   ASTC shall have the right to manufacture ASTC Products in the
             Territory.  DISTRIBUTOR expressly acknowledges that it is granted
             no rights under this Agreement to manufacture any ASTC Product.

     20.2.   Each of the parties hereto represents and warrants that it has not
             employed any broker or finder in connection with this Agreement or
             the transactions contemplated herein.


     20.3.   If any provision or provisions of this International Distribution
             Agreement, including these Standard Terms and Conditions, shall be
             held by a court of competent jurisdiction to be contrary to law,
             such provision or provisions shall be deemed to be null and void
             and the remainder of the Distribution Agreement and these Standard
             Terms and conditions shall nonetheless remain in full force and
             effect.

     20.4.   This Agreement may be executed in any number of counterparts, each
             of which when so executed and delivered shall be deemed to be an
             original, and all of which when taken together shall constitute one
             and the same instrument.

     20.5.   Headings and captions are included herein solely for convenience
             and reference, and do not constitute a part of this Agreement for
             any other purpose.

     20.6.   The English language version of this Agreement shall be definitive
             and shall control over any translation hereof.

21.  RESOLUTION OF DISPUTES:

     21.1.   Any dispute arising out of or with respect to this Agreement shall
             be referred to an arbitration proceeding to be conducted in Boston,

             its designee.  Except as otherwise determined by the duly appointed

             such arbitration shall be the then effective rules of the American

     21.2.   Any award rendered in such arbitration shall be final and binding
             upon the parties, and may be enforced in any court of competent
             jurisdiction.  Any monetary award shall be made and paid in United
             States dollars.  The arbitration shall be conducted in the English
             language, and all evidence submitted to such arbitration shall be
             submitted in the English language.

     21.3.   ASTC and DISTRIBUTOR expressly agree that the Arbitrator shall have
             the power to, at the request of ASTC,

             21.3.1.     issue an interim order or award requiring DISTRIBUTOR
                         to cease sale and distribution of ASTC Products pending

and invoicing of all Systems in North America and the collection of accounts
receivable therefrom; provided that, in those instances where Medtronic
reasonably believes it is necessary for Medtronic to invoice sales of Systems to
a customer under Medtronic's "strategic alliance" sales program (in order for
Medtronic to obtain credit under such program for the sale of such System),
Vista and Medtronic shall cooperate to have Vista invoice Medtronic for such
Systems and thereby allow Medtronic to invoice the sales of Systems to such
"strategic alliance" customer.  Vista shall be responsible for obtaining all

Systems, provided that Medtronic shall bear its proportional share of the cost
for any such training.  Notwithstanding the foregoing, Medtronic and Vista shall
share the cost of training at those designated "centers of excellence", if any,
as the parties may mutually agree, with the sites, strategy, scope and cost of
such training as may be mutually agreed to by the parties.

expense and in Medtronic's name, all necessary regulatory and other approvals
from the applicable regulatory agencies prerequisite to the commercial sale of
the Systems in the Field of Use in the Middle East and Africa.  Such approval
efforts shall include, but not necessarily be limited to, the preparation and
filing of any required filings and the establishment and oversight of any
required clinical investigations and clinical follow-up relating to future
commercial sale of the Systems in the Field of Use in the Middle East and
Africa.

    (b)  In Europe, Vista will be responsible for gaining, at Vista's expense
and in Vista's name, the CE Mark under the appropriate Medical Device Directive.

of all its own labeling.  Medtronic will also be named as the "Authorized
Representative" as defined in the Directives.  Medtronic may also distribute
Systems in particular countries within Europe under country-specific regulatory
approvals prior to Vista's gaining the CE Mark or in particular countries where
CE Mark approval is not the requisite form of commercial sale approval, and in
such circumstances Vista shall (i) provide Medtronic with such information and
cooperation as is necessary to obtain any such country-specific approvals in
Europe, (ii) bear the expenses of meeting any applicable product design and
manufacturing facility requirements, and (iii) take all steps as are necessary

accepted accounting principles as then currently applied by Vista, as
applicable, plus a projected mark-up presently estimated to be *** but in no
event less than ***, subject to final determination as hereinafter provided. 
Such transfer price shall be finally determined by the parties based on market
conditions at the time of commercial introduction of the Systems; provided that
in no event shall the price to Medtronic of a standard System exceed U.S.   * *
*. (The components of the current standard System, exclusive of accessories and
disposables, are listed on Schedule 3.3).  No later than   * * *         , and
by         * * *     thereafter, the parties shall amend the Transfer Price for
the following   * * *      period pursuant to a formula to be mutually agreed to
by the parties, taking into account then market conditions.

    (b)  In addition, Medtronic shall be entitled to purchase from Vista a
reasonable number of demonstration Systems at a price equal to Vista's   * * *  
       * * *          for a System as determined above.  Such reasonable number

the number of Medtronic's "sales specialists" and the number of demonstrations
to be conducted by such sales specialists in connection with selling the
Systems.

    (c)  Payments made by Medtronic for Systems purchased hereunder shall be
due and payable in full within   * * *    days after the date of invoice by
Vista.

    3.4) INSPECTION AND WARRANTY.

    (a)  In the event of any shortage, damage or discrepancy in or to a
shipment of Systems or in the event any of the Systems fail to comply with the
then current specifications for the Systems, Medtronic shall report the same to
Vista and furnish such written evidence or other documentation as Vista
reasonably may deem appropriate.  If the substantiating evidence delivered by
Medtronic demonstrates that such shortage, damage or discrepancy or non-
conformity with specifications existed at the time of delivery of the Systems at
the F.O.B. point, Medtronic may return the Systems to Vista at Vista' expense,
and at Medtronic's request Vista shall use all reasonable efforts to deliver
promptly replacement Systems to Medtronic in accordance with the delivery
procedures set forth herein.

    (b)  Vista represents and warrants to Medtronic that all Systems sold and
delivered to any account under this Agreement will have been manufactured, if
required by law, in accordance with FDA Good Manufacturing Practices, European
Medical Device Directive requirements, ISO 9001 certification or successor
requirements, and all other applicable manufacturing requirements, and that
continually during the term of this Agreement no Systems delivered by Vista to
Medtronic or to any Medtronic Account shall be adulterated or misbranded at the
time of delivery within the meaning of the U.S. Food, Drug and Cosmetic Act and
regulations thereunder.  Vista shall cause Medtronic's regulatory personnel to
be provided with reasonable access from time to time to the facilities and
records of Vista for the purpose of confirming Vista's compliance with all
applicable requirements noted in this Section.

    (b)  For a period of *** days after Medtronic's receipt of Vista's Notice
(the "Exclusive Period"), Vista shall negotiate in good faith exclusively with
Medtronic regarding such distribution or sales representative agreement for the
applicable region specified in Vista's Notice.  During the Exclusive Period,

any third party regarding any distribution or sales representative relationship
for Systems in such region.

    (c)  If Medtronic and Vista fail to reach mutual agreement upon the terms

third party for the applicable region specified in Vista's Notice; provided 
that Vista may not enter into such definitive agreements unless the terms and 
provisions thereof are, in the aggregate, more favorable to Vista than the 
terms and provisions proposed by Medtronic during the Exclusive Period.  If 
Vista fails to enter into such definitive agreement for the applicable region 
within such  * * * period, then Medtronic's rights under this Section shall 
be reinstated and Vista may not enter into any distribution or sales

and continue until the third anniversary of the initial commercial release of
Systems in Europe.

    6.2) RENEWAL TERM: PERFORMANCE OBJECTIVES.

    (a)  The Initial Term shall be automatically renewed for an additional
two-year period (the "Renewal Term"), unless such Initial Term has been
terminated by Vista due to Medtronic's failure to achieve certain reasonable and
mutually agreeable performance objectives to be established by the parties (the
"Performance Objectives").  There shall be one set of Performance Objectives
with respect to Medtronic's rights and obligations as the sales agent for
Systems in North America on an aggregate basis, and one set of Performance
Objectives with respect to Medtronic's rights and obligations as the exclusive
distributor for Systems in Europe, the Middle East and Africa on an aggregate
basis.

    (b)  Vista and Medtronic shall negotiate in good-faith to establish on or
before December 31, 1997 the Performance Objectives for the Initial Term.  The
Performance Objectives shall take into account such factors as the size of the
market, price of the Systems, potential applications of the Systems, selling
cycle, Vista's manufacturing capacity, size of the relative sales forces, and
other relevant factors.  The Performance Objectives for Europe, the Middle East
and Africa shall include aggregate sales volume targets and regulatory approval
requirements.

    (c)  The parties shall, within *** days preceding the commencement of the
Renewal Term, establish mutually acceptable Performance Objectives for such
Renewal Term.

    6.3) TERMINATION FOR FAILURE TO MEET PERFORMANCE OBJECTIVES OR ABANDONMENT
OF AREA.

    (a)  Subject to Article 8 hereof, if Medtronic fails to meet the
Performance Objectives for North America, Vista shall have the right to
terminate Medtronic's rights and obligations as sales agent for North America. 
Subject to Article 8 hereof, if Medtronic fails to meet the Performance
Objectives for Europe, the Middle East, and Africa, Vista shall have the right
to terminate Medtronic's rights and obligations as distributor for Europe, the
Middle East and Africa.  Vista shall give Medtronic written notice of any such
intent to terminate, and Medtronic shall have    * * *       in which to cure
such failure to meet the Performance Objectives.  Vista's rights under this
Section 6.3(a) shall be Vista's sole and exclusive remedy for Medtronic's
failure to meet the Performance Objectives.

    (b)  In addition to Vista's rights under subsection (a) above and whether
or not Medtronic has met the aggregate Performance Objectives for Europe, the
Middle East and Africa, if at any time after commercial release of the Systems
Medtronic is making no efforts (and has no plans to make such efforts) to sell,
distribute, or promote the Systems in Europe, the Middle East, or Africa, then
Vista shall have the right to

* * * Confidential Treatment Requested

<PAGE>


terminate Medtronic's rights and obligations as distributor with respect to 
such geographic area in which no efforts are being made or are planned (i.e. 
either Europe, the Middle East or Africa, as applicable).  Vista shall give 
Medtronic written notice of any such intent to terminate, and Medtronic shall 
have    * * *    in which to commence such sales efforts (or provide a plan to 
commence such sales efforts) in such geographic area.  Except as provided in 
Subsection 6.3(a), Vista's rights under this Subsection 6.3(b) shall be 
Vista's sole and exclusive remedy for any failure by Medtronic to sell, 
distribute or promote the Systems.

    (c)  Upon any such termination pursuant to Subsections 6.3(a) or 6.3(b)
above, Vista will repurchase from Medtronic, at Medtronic's cost, Medtronic's
entire inventory of Systems (excluding demonstration Systems) and related
accessories that do not contain Medtronic's name or trademarks as of the
termination date relating to the geographic area to which such termination
relates.

    (d)  If (i) Vista has elected to utilize a "procedure-based pricing
strategy" in North America (which strategy would involve the payment of
Medtronic's commission over the collective term of all individual System
agreements), and (ii) Vista terminates Medtronic's rights and obligations as its
North American sales agent for failure to meet the Performance Objectives
pursuant to subsection (a) above, Vista shall continue to pay
Medtronic on a   * * *   basis       * * *                                    
   * * *    which would have become due and payable but for such termination on 
each such North America "procedure-based pricing" customer agreement in effect
on the termination date for the                         * * *                   
or (ii)    * * *       .  This formula is intended to recognize that such
customer agreements were entered into during the period that Medtronic was
Vista's sales agent, and that Medtronic's revenue-based commissions were to be
paid over the term of each such agreement.

    6.4) TERMINATION FOR CHANGE OF CONTROL.

    (a)  Vista shall be entitled to terminate Medtronic's rights and
obligations as sales agent for North America if Vista has afforded to Medtronic
its "First Offer Purchase Rights" pursuant to Section 2.1 of the Supplemental
Rights Agreement with respect to a "Proposed Transaction" (as such terms are
defined in the Supplemental Rights Agreement) and such "Proposed Transaction"
has resulted in a Change of Control of Vista.  On or before such Change of
Control, Vista shall give Medtronic written notice of any such intent to
terminate, which termination shall be effective six months after the effective
date of the Change of Control.

    (b)  Upon any such termination pursuant to Subsection 6.4(a) above, Vista
will repurchase from Medtronic, at Medtronic's cost, Medtronic's entire
inventory of Systems (including demonstration Systems) and related materials
that do not contain Medtronic's name or trademarks as of the termination date
relating to the geographic area to which such termination relates.

    (c)  Upon any such termination pursuant to Subsection 6.4(a) above, if
Vista has elected to utilize a "procedure-based pricing strategy" in North
America, Vista shall continue to pay Medtronic for       * * *                  
 * * *     which would have become due and payable but for such termination on
all such North America "procedure-based pricing" customer agreements in effect
on the termination date.

    (d)  In no event, however, shall Vista have the right to terminate
Medtronic's rights as the exclusive distributor for the Systems in Europe, the
Middle East and Africa, or any other region, by reason of any "Change of
Control" of Vista.

obligations under this Agreement with respect to Article 2 and/or Article 3 of
this Agreement, then Medtronic shall be entitled to terminate Medtronic's rights
and obligations under Article 2 and/or, at Medtronic's election, Article 3 of
this Agreement.  Medtronic shall give Vista written notice of any such intent to
terminate, specifying whether such termination will apply to Medtronic's rights
and obligations under Article 2 or Article 3, or both, and Vista shall have     
* * *      in which to cure such material breach.

    (b)  Upon any such termination pursuant to Subsection 6.5(a) above, Vista
will repurchase from Medtronic, at Medtronic's cost, Medtronic's entire
inventory of Systems (including demonstration Systems) and related materials
that do not contain Medtronic's name or trademarks as of the termination date
relating to Medtronic's rights and obligations under Article 2 and/or Article 3
of this Agreement, as applicable.

    (c)  Upon any such termination pursuant to Subsection 6.5(a) above with
respect to Medtronic's rights and obligations under Article 2, if Vista has
elected to utilize a "procedure-based pricing strategy" in North America, Vista
shall continue to pay Medtronic for      * * *                    which
would have become due and payable but for such termination on all such North
America "procedure-based pricing" customer agreements in effect on the
termination date.

    6.6) VISTA'S TERMINATION FOR MEDTRONIC BREACH.

    (a)  Subject to Article 8 hereof and except as otherwise provided in
Section 6.3, if Medtronic breaches any of its material obligations under this
Agreement with respect to Article 2 and/or Article 3 of this Agreement, then
Vista shall be entitled to terminate Medtronic's rights and obligations under

                                   INDEMNIFICATION

    7.1) VISTA'S LIABILITY.  Vista shall indemnify, defend and hold harmless
Medtronic and each of its subsidiaries, officers, directors, employees,
shareholders and distributors from and against and in respect of any and all
demands, claims, actions or causes of action, assessments, losses, damages,
liabilities, interest and penalties, costs and expenses (including, without
limitation, reasonable legal fees and disbursements incurred in connection
therewith and in seeking indemnification therefor, and any amounts or expenses
required to be paid or incurred in connection with any action, suit, proceeding,
claim, appeal, demand, assessment or judgment) ("Indemnifiable Losses"),
resulting from, arising out of, or imposed upon or incurred by any person to be
indemnified hereunder by reason of (i) any breach of representation, warranty,
covenant or agreement on the part of Vista under this Agreement, (ii) total or
partial Systems recalls, or (iii) alleged defects in materials, workmanship,
product performance, or design of the Systems, but in any event excluding
matters for which Medtronic is responsible under Section 7.2 below.  Vista shall
maintain product liability insurance or self-insurance in such amounts as is
advisable pursuant to ordinary good business practice for a similar company in a
similar type of business, and shall provide Medtronic with evidence of this
coverage.

    7.2) MEDTRONIC'S LIABILITY.  Medtronic shall indemnify, defend and hold
harmless Vista and each of its subsidiaries, officers, directors, employees,
shareholders and suppliers from and against and in respect of any and all
demands, claims, actions or causes of action, assessments, losses, damages,
liabilities, interest and penalties, costs and expenses (including, without
limitation, reasonable legal fees and disbursements incurred in connection
therewith and in seeking indemnification therefor, and any amounts or expenses
required to be paid or incurred in connection with any action, suit, proceeding,
claim, appeal, demand, assessment or judgment) ("Indemnifiable Losses"),
resulting from, arising out of, or imposed upon or incurred by any person to be
indemnified hereunder by reason of (i) any breach of representation, warranty,
covenant, or agreement on the part of Medtronic under this Agreement, (ii)
product claims whether written or oral, made or alleged to be made, by Medtronic
in its advertising, publicity, promotion, or sale of any Systems where such
product claims were not provided by or approved by Vista, or (iii) negligent
handling by Medtronic of the Systems, but in any event excluding matters for
which Vista is responsible under Section 7.1 above.

    7.3) THIRD PARTY CLAIMS.  If a claim by a third party is made against any
indemnified party, and if the indemnified party intends to seek indemnity with
respect thereto under this Article 7, such indemnified party shall promptly
notify the indemnifying party of such claim; provided, however, that failure to
give timely notice shall not affect the rights of the indemnified party so long
as the failure to give timely notice does not materially adversely affect the
indemnifying party's ability to defend such claim against a third party.  The
indemnifying party shall be entitled to settle or assume the defense of such
claim, including the employment of counsel reasonably satisfactory to the
indemnified party, as provided below.  If the indemnifying party elects to
settle or defend such claim, it shall notify the indemnified party within thirty
(30) days (but in no


                                         -20-

<PAGE>


event less than twenty (20) days before any pleading, filing or response on
behalf of the indemnified party is due) of its intent to do so.  If the
indemnifying party elects not to settle or defend such claim or fails to notify
the indemnified party of its election within thirty (30) days (or such shorter
period provided above) after receipt of the indemnified party's notice of a
claim of indemnity hereunder, the indemnified party shall have the right to
contest, settle or compromise the claim without prejudice to any rights to
indemnification hereunder.  Regardless of which party is controlling the
settlement or defense of any claim, (i) both the indemnified party and
indemnifying party shall act in good faith, (ii) the indemnifying party shall
not thereby permit to exist any lien, encumbrance or other adverse charge upon
any asset of any indemnified party or of its subsidiaries, (iii) the
indemnifying party shall permit the indemnified party to participate in such
settlement or defense through counsel chosen by the indemnified party, provided
that all fees, costs and expenses of such counsel in an action controlled by the
indemnifying party shall be borne by the indemnified party, unless the
indemnifying party and indemnified party have different available defenses to
such third party claim, in which case such fees, costs and expenses shall be
borne by the indemnifying party, (iv) no entry of judgment or settlement of a
claim may be agreed to without the written consent of both the indemnified party
and the indemnifying party, which consents shall not be unreasonably withheld,
and (v) the indemnifying party shall agree promptly to reimburse the indemnified
party for the full amount of such claim pursuant to this Article 7. So long as
the indemnifying party is reasonably contesting any such claim in good faith as
permitted herein, the indemnified party shall not pay or settle any such claim;
provided that the indemnified party may settle any such claim so long as the
indemnifying party is not adversely affected thereby.  The controlling party
shall deliver, or cause to be delivered, to the other party copies of all
correspondence, pleadings, motions, briefs, appeals or other written statements
relating to or submitted in connection with the settlement or defense of any
such claim, and timely notices of, and the right to participate pursuant to
(iii) above in any hearing or other court proceeding relating to such claim.

    7.4) COOPERATION AS TO INDEMNIFIED LIABILITY.  Each party hereto shall
cooperate fully with the other parties with respect to access to books, records,
or other documentation within such party's control, if deemed reasonably
necessary or appropriate by any party in the defense of any claim which may give
rise to indemnification hereunder.

existing as of the date of signature of this Agreement, not reasonably
foreseeable as of such date and not reasonably within the control of either
party, which prevents in whole or in material part the performance by one of the
parties of its obligations hereunder, such as act of God, act of government, war
or related actions, civil insurrection, riot, sabotage, strike, epidemic, fire,
flood, windstorm, and similar events.

event of Force Majeure shall be released without any liability on its part from
the performance of its obligations under this Agreement, except for the
obligation to pay any amounts due and owing hereunder, but only to the extent
and only for the period that its performance of such obligations is prevented by
the event of Force Majeure.

    8.3) SUSPENSION OF PERFORMANCE.  During the period that the performance by
one of the parties of its obligations under this Agreement has been suspended by
reason of an event of Force Majeure, the other party may likewise suspend the

suspension is commercially reasonable.

no right, title or interest in such Vista trademarks, trade names and logotypes,
other than as provided for above, and Medtronic shall not use any Vista
trademarks, trade names and logotypes as part of Medtronic's corporate or trade
name or permit any third party under Medtronic's control to do so without the
prior written consent of Vista.  All rights under this Section 9.1 shall
terminate upon termination of this Agreement under Article 6, subject to Section
6.5(b).

    9.2) OWNERSHIP.  Vista represents and warrants to Medtronic the following:
Vista is the exclusive owner or licensee of all right, title and interest in and
to all Intellectual Property used in the research, design, development,
manufacture or sale of the Systems (the "Vista Intellectual Property") free and
clear of any liens, charges, security interests, mortgages, pledges,

intellectual property rights or contract rights, of others.  To the knowledge of
Vista, the Vista Intellectual Property is valid and has not been challenged in
any judicial or administrative proceeding.  To the knowledge of Vista, Vista has
not failed to take any necessary steps or appropriate actions to record its
interests, or to protect its rights, in the Vista Intellectual Property.  To the

     3.2  TRAINING MATERIALS.  Members of Vista's and Heartport's management
will work together to prepare all training materials with respect to Vista
Systems that are provided to Heartport trainees at HRTC.  Such training material
will be subject to the written approval of at least one (1) member of the senior
management of each of Heartport and Vista prior to its distribution to Heartport
trainees.

4.   VISTA SYSTEM COMPATIBILITY.  During the Services Term and for a period of
* * * years thereafter, Vista and Heartport agree to mutually evaluate new
software or digital signal processing technology or similar technology useful in
the performance of Port-Access Procedures.  If the parties mutually determine in
good faith that it would be commercially and technically appropriate, they will
work together using commercially reasonable efforts with the goal of ensuring
that the Vista System, including, without limitation, the Vista CardioView-TM-
Display, is compatible with such software or digital signal processing or
similar technology.  Notwithstanding the foregoing, Vista agrees to work with
Heartport using commercially reasonable efforts to satisfy Heartport's
reasonable requests for inclusion of specified features in the Vista CardioView-
TM- Display that relate to Port-Access Procedures.

5.   PROMOTIONAL ACTIVITY.  During the Services Term, Heartport will promote
that its HRTC training courses utilize Vista Systems and will endorse such Vista
Systems as the preferred three-dimensional video visualization and information
solution for minimally invasive cardiac surgery and Vista will promote that
Heartport's HRTC training course utilize Vista Systems.  Such promotional
activity will be subject to the written approval of at least one (1) member of
the senior management of each of Heartport and Vista prior to its distribution.
Heartport will provide Vista with lists of the names and hospital affiliations
of the HRTC trainee surgeons on at least a quarterly basis.  Heartport also
agrees to endorse such Vista Systems as a preferred three-dimensional video
visualization and information solution for minimally invasive cardiac surgery
after the Services Term for so long as Vista is obligated to sell Vista Systems
to Port-Access Hospitals pursuant to Article 6 hereof.

6.   SUPPLY TO PORT-ACCESS HOSPITALS.

     6.1  NON-DISCRIMINATION.  During the Services Term and for four (4) years
thereafter (the "Supply Term"), Vista will sell Vista Systems to each Port-
Access Hospital without discrimination and on the best available terms and
conditions it offers to any other similarly situated Vista customer in North
America purchasing similar quantities of Vista Systems (whether on a per unit
payment basis or on a per procedure payment basis).  Such terms and conditions
include, without limitation, price, priority of delivery, warranty, service and
rights to receive upgrades.  For purposes of this Agreement, "similarly
situated" shall be determined by Vista in good faith based on factors such as
quantity ordered, number of procedures performed, payment, delivery and services
terms, revenues anticipated to be generated at the site, quantities already
installed or

* * * Confidential Treatment Requested

committed to be installed and geographic considerations.        * * *
                         * * *
                         * * *
If a Port-Access Hospital places an order for one (1) or more Vista Systems (or
procedures) the aggregate number of which is not eligible for a volume discount,
the best available terms and conditions shall be determined by reference to
similar sales to other Vista customers in North America.  Notwithstanding the
foregoing, in the event Vista sells Vista Systems in North America as a kit with
other products, the best available terms and conditions for Vista Systems shall
be determined by the following equation:

Price (the "New Price") for stand-alone Vista System if Vista sells as a kit
with other products = (A/A+B)C

where


                                       ***






                                       ***




     If a product or relevant Vista System is not sold      * * *
* * *, the parties shall in good faith mutually agree upon a fair price for
such component of the formula.  The determination of price for a        * * *
        * * *                          shall take into account the fairest
determination of    * * *          given the circumstances
* * *
* * *                        .  Nothing in this Article 6 shall prevent Vista
from implementing reasonable price increases for Vista Systems, provided that
such increases apply equally to all similarly situated Vista customers in North
America.

     6.2  MEET AND CONFER.  The parties agree that Vista's obligations pursuant
to this Article 6 are an important component of the consideration for this
Agreement.  In the event of a misunderstanding between the parties with respect
to the terms of this Article 6, each party hereby represents and warrants to the
other party that at least one (1) member of its senior management will meet with
at least one (1) member of the senior management of the other party within no
more than fifteen (15) days after

<PAGE>

receiving written notice of the other party's concern or request for
clarification under this Article 6.  The parties agree to discuss the concern or
request for clarification in good faith with the goal of resolving the
misunderstanding to the satisfaction of both parties.  In addition, the parties
agree that during the period of discussion covered by this Section 6.2 that each
party will honor reasonable requests for the review of its records related to
the misunderstanding.  In the event that the party giving notice of the concern
or requested clarification is not satisfied with the results of negotiation
after thirty (30) days from the date of the first meeting between the parties,
such party shall have the right to pursue other remedies available under the
terms of this Agreement.

     6.3  EXTENSION OF SUPPLY TERM.  At Heartport's request, Vista will
negotiate in good faith to extend the Services Term and/or the Supply Term on
mutually acceptable terms.

7.   CONFIDENTIALITY.

     7.1  Each party acknowledges the importance of the other party's
Proprietary Information.  Each party agrees (i) to hold the other party's
Proprietary Information in confidence and to take all reasonable precautions to
protect such Proprietary Information (including, without limitation, all
precautions such party employs with respect to its confidential materials),
(ii) not to divulge any such Proprietary Information or any information derived
therefrom to any third person (including Affiliates, except on a "need to know"
basis, (iii) not to make any use whatsoever at any time of such Proprietary
Information except as expressly authorized in this Agreement and (iv) not to
copy, study, analyze, examine or reverse engineer any such Proprietary
Information except as expressly authorized in this Agreement.  Any employee or
contractor given access to any such Proprietary Information must have a
legitimate "need to know" and shall be similarly bound.

     7.2  Without granting any right or license, each party agrees that
Section 7.1 shall not apply to information a party can document (i) is in or,
through no improper action or inaction by such party or any Affiliate, agent or
employee, enters the public domain (and is readily available without substantial
effort), or (ii) was rightfully disclosed to it by a third party not under
restriction not to disclose such information, or (iii) was independently
developed by it by persons without access to, or use of, any Proprietary
Information of the other party.  A party must promptly notify the other party of
any information it believes comes within any circumstance listed in the
immediately preceding sentence and will bear the burden of proving the existence
of any such circumstance by clear and convincing evidence.

     7.3  Immediately upon (i) termination of this Agreement or (ii) a party's
earlier written request, a receiving party will turn over to the disclosing
party all of such disclosing party's Proprietary Information and all documents
or media containing any


                                       -7-

<PAGE>

such Proprietary Information (and any and all copies or extracts thereof) and
shall have an officer of such party so certify to the disclosing party in
writing.  In such instance, each party's chief legal officer may retain one
archival copy of the other party's Proprietary Information in secure files,
provided, however, that if such copies are retained, the officer's certificate
referred to in this Section 7.3 shall so state.

     7.4  Each party acknowledges and agrees that due to the unique nature of
the other party's Proprietary Information, there can be no adequate remedy at
law for any breach of its obligations hereunder, that any such breach may allow
the receiving party or third parties to unfairly compete with the disclosing
party resulting in irreparable harm to the disclosing party, and, therefore,
upon any such breach or any threat thereof, the disclosing party shall be
entitled to appropriate equitable relief in addition to whatever remedies it
might have at law and to be indemnified by receiving party from any loss or
harm, including, without limitation, lost profits and attorney's fees, in
connection with the unauthorized use or release of any Proprietary Information
of the disclosing party or breach of this Article 7.  A receiving party shall be
obligated to notify the disclosing party in writing immediately upon the
occurrence of any such unauthorized use or release or breach of this Article 7.

     7.5  The obligations imposed by Sections 7.1 and 7.2 with respect to the
protection of Proprietary Information shall continue for a period of    * * *
   following disclosure of such Proprietary Information unless otherwise agreed
to in writing by the parties.

Agreement.

     8.2  TERMINATION BY EITHER PARTY.  If either party is in material breach of
one or more provisions of this Agreement, the Agreement may be terminated by the
non-breaching party if the breach is not cured by the breaching party within

The breach may be cured after    * * *    days of such notification by mutual
written agreement of the parties.

     8.3  SURVIVAL.  Except as otherwise set forth in this Agreement, upon the
termination or expiration of this Agreement, all rights and obligations of the
parties under this Agreement shall cease, except that the provisions of
Articles 7 and 9 and this Section 8.3 shall survive and any other provisions
which by their terms or nature are intended to survive such termination or
expiration shall survive and continue to be enforceable.  Notwithstanding the

part without the prior written consent of the other party, except that neither

     9.12 ENTIRE AGREEMENT.  This Agreement together with any Appendices and

October 16, 1995, between the parties, constitute the entire agreement between
the parties relating to the subject matter hereof, and supersede all prior or

shall be available to such arbitrator(s); provided, however, that the parties
expressly agree that neither party will seek, nor shall the arbitrator(s) be

determination that consequential damages are to be awarded and the amount of
such consequential damages (and no other finding of the arbitrator) to any court
having jurisdiction of the matter, and, if so submitted, the arbitrator's award

arbitrator shall have authority to alter, amend, add to, subtract from or
supplement the Agreement to grant punitive or exemplary damages.  Judgment upon
the award rendered may be entered in any court having jurisdiction of the
matter.  The arbitrators shall be instructed, in connection with the

described in subsection (b) below without first giving Vista's Notice (as

    (b)   In the event that (referred to as a "Proposed Transaction"):

          (i)   Vista receives a bona fide offer from a third party to
          purchase, in one or more transactions, all or substantially all of
          the outstanding capital stock of Vista, or to purchase, license or

<PAGE>

          (ii)  Vista receives a bona fide offer from a Medtronic Competitor to

          *** or more of the issued and outstanding capital stock of Vista, or

          outstanding capital stock of Vista (other than in a public offering)
          (including, without limitation, a determination to seek indications
          of interest with respect to such a transaction);

then Vista shall, within    * * *      after such event notify Medtronic in
writing of Vista's receipt of such offer described in (i) or (ii) above or of
Vista's determination described in (iii) above ("Vista's Notice").  Vista's

with Medtronic.

    (c)   During the Exclusive Period, Vista shall negotiate in good faith

Transaction or any comparable transaction.

    (d)   If Medtronic and Vista fail to reach mutual agreement upon the terms

described in (b)(iii) above); provided that Vista may not enter into such

Definitive Agreements with respect to such particular Proposed Transaction
within such  * * * period or if such Proposed Transaction is not completed
within  * * *   after the expiration of the Exclusive Period, then Medtronic's
rights under this Section shall be reinstated and Vista may not enter into such
Proposed Transaction without first giving Medtronic a new Vista's Notice and
complying with the terms of this Section 2.1.

    (e)   Medtronic's "First Offer Purchase Rights" pursuant to this Section
2.1 shall terminate upon the earlier of (i) the   * * *   anniversary of the
date of this Agreement, (ii) the closing of a public offering of Vista
securities registered on Form S-1 or SB-2 (or comparable forms) which results in

with Medtronic's "First Offer Purchase Rights" pursuant to this Section 2.1 with
respect to a Proposed Transaction and such Proposed Transaction has resulted in
a Change of Control of Vista.

    2.2)  BOARD REPRESENTATIVE.

    (a)   So long as Medtronic (together with its Affiliates) owns at least an
aggregate of *** of the issued and outstanding shares of Vista Common Stock
(assuming conversion of all Vista Preferred Stock) (appropriately adjusted in
the event of stock splits, reverse stock splits, or dividends paid in the form
of Vista stock), Vista shall permit Medtronic to designate one representative
reasonably acceptable to Vista as an observer to the Board of Directors or,
anytime after December 31, 1997 if Medtronic so elects in its discretion, as a
member of the Board of Directors.  If Medtronic's representative has a change in
employment responsibilities or ceases to be employed by Medtronic, Medtronic
shall be entitled to designate a replacement for its representative.
Medtronic's representative shall receive all notices, documents, and other
information in the same time and manner as such information is supplied to
members of the Board of Directors.  Vista shall make reasonable efforts to
permit Medtronic's representative to participate in or observe Board of
Directors meetings by telephone if such representative is unable to attend in
person.  Vista agrees to pay the reasonable expenses incurred by Medtronic's
representative in connection with attending Board of Directors meetings as a
member of (but not as an observer to) the Board of Directors if and to the
extent that Vista pays any expenses of any other member of the Board of
Directors.

    (b)   So long as Medtronic has the right to have a representative to the
Board of Directors pursuant to (a) above and does not elect to have such
representative become a member of the Board of Directors, Medtronic shall
receive from Vista notices of all meetings of the Board of Directors, including
without limitation telephonic meetings, and Medtronic shall receive, with such
limitations provided herein, any materials distributed for such meeting, and may
send one representative to such meetings.

    (c)   Notwithstanding the foregoing subsection (a) and (b), Vista may
require as a condition precedent that such Medtronic's representative proposing
to attend any meeting of the Board of Directors shall agree to hold in
confidence and trust, and to act in a fiduciary manner if such individual is a
Board member with respect to all information so received during such meetings
and may require that such representative sign a confidentiality agreement with
Vista and; provided, further, that Vista reserves the right not to provide
information and to exclude such representative from any meeting or portion
thereof if attendance at such meeting by such representative or dissemination of

                                         -6-

<PAGE>

any information at such meeting to such representative would, in the good faith
judgment of the Board of Directors, would compromise or adversely affect the
attorney-client privilege between Vista and its counsel, or would, in the good
faith judgment of the Board of Directors, result in a conflict of interest
situation.  In no event shall any provision of this Section waive any obligation
of confidentiality to Vista owed by any such representative or Medtronic.

    (d)   Unless Medtronic elects to have its designee to act as a non-voting
observer to the Board of Directors, from and after December 31, 1997, the Board
of Directors agrees to nominate Medtronic's designee for election to the Board
of Directors and Vista agrees to use its best efforts to cause Medtronic's
designee to be so elected.

    (e)   Medtronic's rights pursuant to this Section 2.2 shall terminate upon
the earlier of (i) the closing of a public offering of Vista securities
registered on Form S-1 or SB-2 (or comparable forms) which results in net
proceeds to Vista of more than ***    * * *   or (ii) if Vista has complied with
Medtronic's "First Offer Purchase Rights" pursuant to Section 2.1 with respect
to a Proposed Transaction and such Proposed Transaction has resulted in a Change
of Control of Vista.

    2.3)  INVESTORS' RIGHTS AGREEMENT.  Vista agrees not to amend, modify or
obtain a waiver of its obligations under the Investors' Rights Agreement in any
manner that discriminates against Medtronic unless Medtronic or MAMI is among
the holders of a majority of Registrable Securities thereunder consenting to
such amendment, modification or waiver.

    2.4)  ISSUANCE OF PREFERRED STOCK.  For so long as Medtronic or its
Affiliates owns any Series C Preferred Stock, Vista agrees not to issue or sell
any shares of Series A-1, Series A-3, or Series B Preferred Stock, or "Options"
to purchase or securities convertible into shares of Series A-1, Series A-3, or
Series B Preferred Stock, for a consideration per share (determined pursuant to
Section B.4.c.(5) of Article IV of Vista's Amended and Restated Certificate of
Incorporation) less than the "Series C Conversion Price" then in effect, except
that this Section shall not apply to issuances or sales described in subparts
(iv) or (v) of Section B.4.c.(1)(d) of Article IV of Vista's Amended and
Restated Certificate of Incorporation.

                                      ARTICLE 3
                                    MISCELLANEOUS

     THIS AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT (the "Agreement") is
made as of the 27th day of November, 1996 (the "Effective Date"), by and between
Vista Medical Technologies, Inc., a Delaware corporation (the "Company"), and
the Stockholders listed on Schedule A hereto, each of which is herein referred
to as a "Stockholder."

                                       RECITALS

     WHEREAS, the Company and certain of the Stockholders (the "Series A
Stockholders") are parties to a certain Investors' Rights Agreement dated as of
July 12, 1996, as amended through the date hereof (the "Prior Agreement"),
pursuant to which certain of the Stockholders possess registration rights,
information rights, rights of first refusal and other rights, and the Company is
obligated thereunder;

     WHEREAS, the Company and one of the Stockholders are parties to the
Series C Preferred Stock Purchase Agreement dated the date hereof (the "Series C
Agreement"); and

     WHEREAS, in order to induce the Company to enter into the Series C
Agreement and to induce such Stockholder to purchase shares of the Company's
Series C Preferred Stock (the "Series C Preferred") pursuant to the Series C
Agreement, the Stockholders and the Company hereby agree that this Agreement
shall amend the Prior Agreement so that this Agreement shall govern the
obligations of the Company to register the resale of shares of Common Stock
issuable to the Stockholders upon conversion of their shares of the Company's
Series A-1 Preferred Stock, Series A-3 Preferred Stock (collectively, the
"Series A Preferred"), Series B Preferred Stock (the "Series B Preferred")
and/or Series C Preferred, and certain other matters as set forth herein.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

                                      SECTION 1.

           RESTRICTIONS ON TRANSFER; REGISTRATION RIGHTS

     1.1   RESTRICTIONS ON TRANSFERABILITY.  Neither the Series A Preferred,
the Series B Preferred or the Series C Preferred nor the Registrable Securities
(as defined below) shall be transferable except upon the conditions specified in
this Agreement, which conditions are intended to insure compliance with the
provisions of the Securities Act (as defined below), or upon such other terms as
are in the opinion of counsel to the Company satisfactory to comply with the
provisions of the Securities Act.  Except for transfers made pursuant to Rule
144 of the Securities Act, the Stockholders will cause any proposed transferee
of Series


                                         -1-

<PAGE>


A Preferred, Series B Preferred, Series C Preferred or Registrable Securities
held by any Stockholder to agree to take and hold such securities subject to the
provisions and upon the conditions specified in this Agreement and it will be a
condition precedent to the effectiveness of any such transfer that the Company
shall have secured a written agreement in form and substance satisfactory to the
Company to that effect, if so requested by the Company,

     1.2   CERTAIN DEFINITIONS.  As used in this Agreement, the following terms
shall have the following respective meanings:

     "COMMISSION" shall mean the Securities and Exchange Commission or any
other federal agency at the time administering the Securities Act.

     "FORM S-3" shall mean Form S-3 under the Securities Act (as defined below)
as in effect on the date of this Agreement, or any substantially similar,
equivalent or successor form under the Securities Act.

     "HOLDER" shall mean each holder of Registrable Securities.

     "REGISTRABLE SECURITIES" means (i) the Common Stock issuable or issued
upon conversion of the Series A Preferred, (ii) the Common Stock issuable or
issued upon conversion of the Series B Preferred, (iii) the Common Stock
issuable or issued upon conversion of the Series C Preferred, and (iv) any
Common Stock of the Company issued as (or issuable upon the conversion or
exercise of any warrant, right or other security which is issued as) a dividend
or other distribution with respect to, or in exchange for or in replacement of,
the shares referenced in (i), (ii) and (iii) above, excluding in all cases,
however, any Registrable Securities sold by a person in a transaction in which
his rights under this Section 1 are not assigned and any Registerable Securities
as to which the registration rights granted hereunder have been terminated
pursuant to Section 1.14.

     The terms "REGISTER," "REGISTERED" and "REGISTRATION" refer to a
registration effected by preparing and filing a registration statement in
compliance with the Securities Act, and the declaration or ordering of the
effectiveness of such registration statement.

     "REGISTRATION EXPENSES" shall mean all expenses incurred by the Company in
complying with Sections 1.5, 1.6 and 1.7 hereof other than Selling Expenses,
including, without limitation, all registration, qualification and filing fees,
printing expenses, escrow fees, fees and disbursements of Company counsel, blue
sky fees and expenses, and the expense of any special audits incident to or
required by any such registration (but excluding the compensation of regular
employees of the Company which shall be paid in any event by the Company).


                                         -2-

<PAGE>


     "RESTRICTED SECURITIES" shall mean the securities of the Company required
to bear the legend set forth in Section 1.3 hereof or a legend substantially
similar thereto and all shares of Common Stock outstanding on the date of this
Agreement.

     "SECURITIES ACT" shall mean the Securities Act of 1933, as amended, or any
similar federal statute and the rules and regulations of the Commission
thereunder, all as the same shall be in effect at the time.

     "SELLING EXPENSES" shall mean all underwriting discounts and selling
commissions applicable to the applicable sale.

     1.3   RESTRICTIVE LEGEND(S).

     (a)   Each certificate representing the shares of Series A Preferred,
Series B Preferred, Series C Preferred and Registrable Securities shall (unless
otherwise permitted by the provisions of Section 1.4 below) be stamped or
otherwise imprinted with a legend in the following form (in addition to any
legend required under applicable California or other state securities laws):

     THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
     AS AMENDED.  SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
     SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT.  COPIES OF THE
     AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND RESTRICTING THEIR
     TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER
     OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE CORPORATION.

     (b)   Each certificate representing shares of Registrable Securities into
which shares of the Series A Preferred, Series B Preferred and/or Series C
Preferred are converted also shall be stamped or otherwise imprinted with any
legend required by the Bylaws of the Company (in addition to any legend required
under applicable California or other state securities laws).

     1.4   NOTICE OF PROPOSED TRANSFERS.  The holder of each certificate
representing the Restricted Securities, by acceptance thereof, agrees to comply
in all respects with the provisions of this Section 1.4. Prior to any proposed
transfer of any Restricted Securities, unless there is in effect a registration
statement under the Securities Act covering the proposed transfer, the holder
thereof shall give written notice to the Company of such holder's intention to
effect such transfer.  Each such notice shall describe the manner and
circumstances of the proposed transfer in sufficient detail, and shall be
accompanied (except in transactions in compliance with Rule 144) by either (i) a
written opinion of legal counsel which shall be reasonably satisfactory to the
Company addressed to the Company and


                                         -3-

<PAGE>


reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act, or (ii) a "no action" letter from
the Commission, a copy of any holder's request (together with all supplements or
amendments thereto) to which shall have been provided to the Company, at or
prior to the time of first delivery to the Commission's staff, to the effect
that the transfer of such securities without registration will not result in a
recommendation by such staff that action be taken with respect thereto,
whereupon the holder of such Restricted Securities shall be entitled to transfer
such Restricted Securities in accordance with the terms of the notice delivered
by the holder to the Company.  Each certificate evidencing the Restricted
Securities transferred as provided for above shall bear the appropriate
restrictive legend set forth in Section 1.3 above, except that such certificate
shall not bear such restrictive legend if, in the opinion of counsel for the
Company or counsel for such holder, such legend is not required in order to
establish compliance with any provisions of the Securities Act.

     Notwithstanding the provisions above, no such opinion of counsel or "no
action letter" shall be necessary for a transfer by a Stockholder which is a
partnership to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such
partner or retired partner ("Partners"), if the transferee agrees in writing to
be subject to the terms hereof to the same extent as if he were an original
Stockholder hereunder.

     1.5   DEMAND REGISTRATION RIGHTS.

     (a)   Commencing on the third anniversary of the Effective Date, if the
Company shall receive a written request (specifying that it is being made
pursuant to this Section 1.5) from the Holders of at least forty percent (40%)
of the Registrable Securities that the Company file a registration statement or
similar document under the Securities Act covering the registration of
Registrable Securities the expected aggregate offering price to the public of
which is at least $7,500,000, then the Company shall promptly notify all other
Holders of such request and shall use its best efforts to cause all Registrable
Securities that such Holders have requested, within fifteen (15) days after
receipt of such written notice, to be registered in accordance with this Section
1.5 to be registered under the Securities Act.  The Holders making the written
request pursuant to this Section 1.5 shall be referred to hereinafter as the
"Initiating Holders".

     Notwithstanding the foregoing, (i) the Company shall not be obligated to
effect a registration pursuant to this Section 1.5 during the period starting
with the date one hundred twenty (120) days prior to the Company's estimated
date of filing of, and ending on a date one hundred eighty (180) days following
the effective date of, a registration statement pertaining to an underwritten
public offering of the Company's securities, provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective and that the Company's estimate of
the date of filing such registration statement is made in good faith; and (ii)
if the Company shall furnish to such


                                         -4-

<PAGE>


Holders a certificate signed by the President of the Company stating that in the
good faith judgment of the Board of Directors it would be seriously detrimental
to the Company or its stockholders for a registration statement to be filed in
the near future, then the Company's obligation to use its best efforts to file a
registration statement shall be deferred for a period not to exceed six (6)
months; provided, however, that the Company shall not obtain such a deferral
more than once in any 12-month period.

     The Company shall be obligated to effect not more than two (2)
registrations pursuant to this Section 1.5 for which holders of Registrable
Securities are the Initiating Holders.

     (b)   If the Initiating Holders intend to distribute the Registrable
Securities covered by their demand by means of an underwriting, they shall so
advise the Company as part of their demand made pursuant to this Section 1.5,
and the Company shall include such information in the notice referred to in
Section 1.5(a). In such event, the right of any Holder to registration pursuant
to this Section 1.5 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority in interest of
the Initiating Holders and such Holder) to the extent provided herein.

     The Company shall, together with all Holders proposing to distribute their
securities through such underwriting, enter into an underwriting agreement in
customary form with the underwriter or underwriters selected by the Company and
reasonably satisfactory to a majority of interest of the Initiating Holders.
Notwithstanding any other provision of this Section 1.5, if the underwriter
shall advise the Company in writing that marketing factors (including, without
limitation, an adverse effect on the per share offering price) require a
limitation of the number of shares to be underwritten, then the Company shall so
advise all Holders of Registrable Securities that would otherwise be registered
and underwritten pursuant hereto, and the number of shares of Registrable
Securities that may be included in the registration and underwriting shall be
allocated pro rata among such Holders thereof in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement.  No Registrable
Securities excluded from the underwriting by reason of the underwriter's
marketing limitation shall be included in such registration.

     If any Holder disapproves of the terms of the underwriting, such Holder
may elect to withdraw therefrom by written notice to the Company, the
underwriter and the Initiating Holders.  The Registrable Securities so withdrawn
shall also be withdrawn from registration.  If by the withdrawal of such
Registrable Securities a greater number of Registrable Securities held by other
Holders may be included in such registration (up to the maximum of any
limitation imposed by the underwriters), then the Company shall offer to all
Holders who have included Registrable Securities in the registration the right
to include additional Registrable Securities in the same proportion used in
determining the underwriter limitation in this Section 1.5.


                                         -5-

<PAGE>


     If the underwriter has not limited the number of Registrable Securities to
be underwritten, the Company may include securities for its own account (or for
the account of other securityholders) in such registration if the underwriter so
agrees and if the number of Registrable Securities that would otherwise have
been included in such registration and underwriting will not thereby be limited.

     1.6   COMPANY REGISTRATION.

     (a)   If, at any time or from time to time, the Company shall determine to
register any of its securities, either for its own account or the account of a
securityholder or holders exercising their respective demand registration
rights, other than a registration relating solely to employee benefit plans on
Form S-8 or similar forms which may be promulgated in the future or a
registration on Form S-4 or similar forms which may be promulgated in the future
relating solely to a Securities and Exchange Commission Rule 145 or similar
transaction the Company will (i) promptly give to each Holder written notice
thereof and (ii) include in such registration (and any related qualification
under Blue Sky laws or other compliance), and in any underwriting involved
therein, all Registrable Securities of such Holders as specified in a written
request or requests made within fifteen (15) days after receipt of such written
notice from the Company.

     (b)   If the registration of which the Company gives notice is for a
registered public offering involving an underwriting, the Company shall so
indicate in the notice given pursuant to Section 1.6(a). In such event the right
of any Holder to registration pursuant to this Section 1.6 shall be conditioned
upon such Holder's agreeing to participate in such underwriting and to the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.  All Holders proposing to distribute their securities
through such underwriting shall (together with the Company and the other Holders
distributing their securities through such underwriting) enter into an
underwriting agreement in customary form with the underwriter or underwriters
selected for such underwriting by the Company or by other holders exercising any
demand registration rights.  Notwithstanding any other provision of this Section
1.6, if the underwriter determines that marketing factors require a limitation
of the number of shares to be underwritten, the underwriter may exclude some or
all Registrable Securities or other securities from such registration and
underwriting (hereinafter an "Underwriter Cutback"); provided, however, that if
such underwriting relates to any registration statement other than a
registration statement being filed with respect to the first registration
statement filed by the Company covering an underwritten offering of any of its
securities to the general public ("Initial Public Offering") in which no
secondary shares are included, then (i) in no event shall the aggregate number
of shares of Registrable Securities included in such underwriting be reduced
below thirty (30%) of the total number of shares proposed to be included in such
underwriting.  In the event of an Underwriter Cutback, the Company shall so
advise all Holders and the other holders distributing their securities through
such underwriting, and the number of Registrable Securities and other securities
that may be included in the registration and underwriting shall be allocated
among all holders thereof (other than those holders who are exercising their
demand registration


                                         -6-

<PAGE>


rights) on the basis that the holders who are not Holders shall be cut back
before any cutback of Holders.  If the limitation determined by the underwriter
requires an Underwriter Cutback, such Underwriter Cutback shall be in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities held by such Holders at the time of filing the registration
statement.  If any Holder disapproves of the terms of any such underwriting,
such Holder may elect to withdraw therefrom by written notice to the Company and
the underwriter.  Any securities excluded or withdrawn from such underwriting
shall be withdrawn from such registration.

     1.7   FORM S-3 REGISTRATION RIGHTS.  After the Initial Public Offering,
the Company shall use its best efforts to qualify for registration on Form S-3,
and to that end the Company shall use its best efforts to comply with the
reporting requirements of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), within twelve (12) months following the effective date of the
first registration of any securities of the Company for an underwritten
registered public offering.  After the Company has qualified for the use of Form
S-3, and subject to the provisions of Section 1.14, each Holder shall have the
right to request registrations on Form S-3 (such requests shall be in writing
and shall state the number of shares of Registrable Securities to be disposed of
and the intended method of disposition of such shares by each such Holder),
subject only to the following limitations:

     (a)   The Company shall not be obligated to cause a registration on Form
S-3 to become effective prior to one hundred eighty (180) days following the
effective date of a Company initiated registration (other than a registration
relating solely to employee benefit plans on Form S-8 or similar forms which may
be promulgated in the future or a registration on Form S-4 or similar forms
which may be promulgated in the future relating solely to a Securities and
Exchange Commission Rule 145 or similar transaction the Company);

     (b)   The Company shall not be required to effect a registration pursuant
to this Section 1.7 unless the Holder or Holders requesting such a registration
propose to dispose of shares of Registrable Securities having an aggregate
disposition price (before deduction of underwriting discounts and expenses of
sale) of at least $500,000;

     (c)   The Company shall not be required to effect a registration pursuant
to this Section 1.7 if the Company shall furnish to the requesting Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company or its stockholders for the registration statement to
be filed at the date filing would be required, in which case the Company shall
have an additional period of not more than one hundred twenty (120) days within
which to file such registration statement; PROVIDED HOWEVER, that the Company
shall not use this right more than once in any 12-month period;

     (d)   The Company shall not be required to maintain and keep any such
registration on Form S-3 effective for a period exceeding one hundred twenty
(120) days from the effective date thereof;


                                         -7-

<PAGE>


     (e)   The Company shall not be obligated to cause a registration on Form
S-3 if in the prior six-month period the Company has caused a registration on
Form S-3 to become effective; and

     (f)   The Company shall be obligated to effect not more than two
registrations per year pursuant to this Section 1.7 for which holders of
Registrable Securities request such registration.

     The Company shall give notice to all Holders of the receipt of a request
for registration pursuant to this Section 1.7 and shall use its best efforts to
cause all Registrable Securities that such Holders have requested, within
fifteen (15) days after receipt of such written notice, be registered in
accordance with this Section 1.7 to be registered under the Securities Act.
Subject to the foregoing, the Company will use its best efforts to effect
promptly any registration pursuant to this Section 1.7. The provisions of
Section 1.5(b) shall apply to any registration effected pursuant to this Section
1.7

     1.8   EXPENSES OF REGISTRATION.  All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Sections 1.5, 1.6 and 1.7 (exclusive of Selling Expenses but inclusive of the
reasonable fees and expenses of one special counsel to the selling Holders)
shall be borne by the Company.  Notwithstanding anything to the contrary herein,
the Company shall not be required to pay for any expenses of any registration
proceeding under Section 1.5 if the registration request is subsequently
withdrawn at the request of the Holders of a majority of the Registrable
Securities to have been registered, unless such Holders agree to forfeit their
right to a demand registration pursuant to Section 1.5 (in which event such
right shall be forfeited by all Holders).  In the absence of such an agreement
to forfeit, the Holders of Registrable Securities to have been registered shall
bear all such expenses pro rata on the basis of the Registrable Securities to
have been registered.  Notwithstanding the foregoing, however, if at the time of
the withdrawal, the Holders have learned of a material adverse change in the
condition, business or prospects of the Company from that known to the Holders
at the time of their request, of which the Company had knowledge at the time of
the request, then the Holders shall not be required to pay any of said expenses
and shall retain their rights pursuant to Section 1.5.

     1.9   REGISTRATION PROCEDURES.  In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 1,
the Company will keep each Holder 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:

     (a)   Keep such registration, qualification or compliance effective for a
period of one hundred twenty (120) days or until the Holder or Holders have

     (b)   Prepare and file with the Commission such amendments and supplements

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;

     (c)   Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the

to facilitate the disposition of Registrable Securities owned by them;

     (d)   Use its best efforts to register and qualify the securities covered

     (e)   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 Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement; and

     (f)   Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is

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.

     Notwithstanding any provision to the contrary in this Agreement, the
Company shall not be required in connection with any registration pursuant to

     1.10  INDEMNIFICATION.

     (a)   The Company will indemnify each Holder, each of its officers and
directors and partners, and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, with respect to which registration,

each underwriter, if any, and each person who controls any underwriter within
the meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any registration statement,

based on any omission (or alleged omission) to state therein a material fact


                                         -9-

<PAGE>


required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, or any
violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will promptly reimburse each such Holder, each of its
officers and directors and partners, and each person controlling such Holder,
each such underwriter and each person who controls any such underwriter, for any
legal and any other expenses reasonably incurred (as and when incurred) in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, provided that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder or underwriter and stated to be specifically for use therein.

     (b)   Each Holder will, if Registrable Securities held by such Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify 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 or such
underwriter within the meaning of Section 15 of the Securities Act, and each
other such Holder, each of its officers and directors and partners and each
person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof) including any of the foregoing incurred in
settlement of any litigation commenced or threatened, arising out of or based on
any untrue statement (or alleged untrue statement) of a material fact contained
in any such registration statement, prospectus, offering circular or other
document, or any amendment or supplement thereto, 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, in the light of the circumstances in
which they were made, not misleading, or any violation by the Company of any
rule or regulation promulgated under the Securities Act applicable to the
Company in connection with any such registration, qualification, or compliance,
and will promptly reimburse the Company, such Holders, such directors,
officer's, partners, persons, underwriters or control persons for any legal or
any other expenses reasonably incurred (as and when incurred) in connection with
investigation, preparing or defending 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 or any amendment or supplement thereto in reliance upon and in
conformity with written information furnished to the Company by an instrument
duty executed by such Holder and stated to be specifically for use therein,
provided, however, that the obligations of each such Holder hereunder shall be
limited to an amount equal to the proceeds to each such Holder of Registrable
Securities sold as contemplated herein.

     (c)   Each party entitled to indemnification under this Section 1.10 (the
"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, and shall
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
withheld), and the Indemnified Party may participate in such defense at its own
expense, and provided further that the failure of any Indemnified Party to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Section 1 unless such failure resulted in actual
detriment to the Indemnifying Party.  No Indemnifying Party, in the defense of
any such claim or litigation, shall, except with the consent of each 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 a release from all liability in respect of
such claim or litigation.

     (d)   If the indemnification provided for in this Section 1.10 is held by
a court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party on the one hand and of the Indemnified Party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations.  The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Indemnifying Party or by the Indemnified
Party and the parties relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

     (e)   The obligations of the Company and Holders under this Section 1.10
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1 and otherwise.

     1.11  INFORMATION BY HOLDER.  The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders and the distribution proposed by
such Holder or Holders as the Company may request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Section 1.

     1.12  RULE 144 REPORTING.  With a view to making available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the


                                         -11

<PAGE>


Restricted Securities to the public without registration, after such time as a
public market exists for the Common Stock of the Company, the Company agrees to:

     (a)   Use its best efforts to make and keep public information available,
as those terms are understood and defined in Rule 144 under the Securities Act
at all times after the effective date of the first registration under the
Securities Act filed by the Company for an offering of its securities to the
general public;

     (b)   Use its best efforts to then file with the Commission in a timely
manner all reports and other documents required of the Company under the
Exchange Act at any time after it has become subject to such reporting
requirements,

     (c)   So long as a Stockholder owns any Restricted Securities, to furnish
to the Stockholder forthwith upon 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 general 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 report of the
Company, and such other reports and documents of the Company as a Stockholder
may reasonably request in availing itself of any rule or regulation of the
Commission allowing a Stockholder to sell any such securities without
registration.

     1.13  TRANSFER OF REGISTRATION RIGHTS.  The rights to cause the Company to
register securities granted under Sections 1.5, 1.6 and 1.7 may be assigned or
otherwise conveyed to a transferee or assignee of Registrable Securities, who
shall be considered a "Holder," and the transferred shares shall be considered
"Registrable Securities," for purposes of this Section 1, provided that (i) said
transferee acquires (or, together with affiliates (as defined under the
Securities Act) ("Affiliates") of said transferee, after the acquisition then
beneficially owns) at least 250,000 shares of the Registrable Securities
(including shares of Series A Preferred, Series B Preferred and Series C
Preferred prior to conversion into Registrable Securities) and (ii) the Company
is given written notice by such Holder at the time of or within a reasonable
time (but not more than thirty (30) days) after said transfer, stating the name
and address of said transferee or assignee and identifying the securities with
respect to which such registration rights are being assigned, subject to said
transferee's agreement to be bound by and comply with the provisions of this
Section 1.

     1.14  TERMINATION OF REGISTRATION RIGHTS.  The registration rights granted
pursuant to this Section 1 shall terminate (i) upon the seventh anniversary of
the effective date of the first registration statement filed by the Company
covering the Initial Public Offering or (ii) if earlier, as to any individual
Holder, at such time after the Company's Initial Public Offering as all
Registrable Securities (including shares of Series A Preferred, Series B
Preferred and Series C Preferred prior to conversion into Registrable
Securities) held by such Holder (together with shares of any other holder whose
sales of Registrable Securities must be aggregated with sales of Holder pursuant
to Rule 144(e)) can be sold within any


                                         -12-

<PAGE>


three-month period without compliance with the registration requirements of the
Securities Act pursuant to Rule 144 (including Rule 144(k)) promulgated
thereunder.

     1.15  "MARKET STAND OFF" AGREEMENT.  Each Holder hereby agrees that,
during the period of duration specified by the Company and an underwriter of
common stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the Act, it shall not, to
the extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it at any time during such period except common stock included in such
registration; PROVIDED, HOWEVER, that:

                 (a)   such agreement shall not exceed 180 days for the first
such registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

                 (b)   such agreement shall not exceed 90 days for any
subsequent registration statement of the Company which covers Common Stock (or
other securities) to be sold on its behalf to the public in an underwritten
offering; and

                 (c)   all executive officers and directors of the Company and
all other persons with registration rights under this Agreement or any other
agreement enter into similar agreements.

                 In order to enforce the foregoing covenant, the Company may
impose stop-transfer instructions with respect to the Registrable Securities of
each Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.  Notwithstanding the
foregoing, the obligations described in this Section 1.15 shall not apply to a
registration relating solely to employee benefit plans on Form S-8 or similar
forms which may be promulgated in the future, or a registration relating solely
to a SEC Rule 145 transaction on Form S-4 or similar forms which may be
promulgated in the future.

                                      SECTION 2.

accounting officer of the Company;

     (c)   An annual operating budget for each coming year, delivered on or
before January 1 of each year; and

     (d)   Such other information relating to the financial condition,
business, prospects or corporate affairs of the Company as the investor may from
time to time request, provided, however, that the Company shall not be obligated
to provide information which it deems proprietary.

     2.2   ASSIGNMENT OF RIGHTS TO FINANCIAL INFORMATION.  The rights granted
pursuant to Section 2.1 may be assigned by the Stockholders (or by any permitted
transferee of any such rights) so long as (i) the Company is given notice of any
such assignment within a reasonable time after the date the same is effected,
(ii) the transferee shall have acquired (or, together with such transferee's
Affiliates, after the acquisition shall then beneficially own) at least 250,000
shares of Registrable Securities (including shares Series A Preferred, Series B
Preferred and Series C Preferred prior to conversion into Registrable
Securities) in a private transaction and (iii) the transferee is not engaged in
a business that is competitive with the Company.

     2.3   INSPECTION RIGHTS.

     (a)   The Company will permit any Investor, so long as such Investor (or
its representative) owns at least 200,000 Shares, or such number of shares of
Common Stock issued upon conversion of 200,000 or more Shares, or any
combination thereof (as presently constituted and subject to subsequent
adjustment for stock splits, stock dividends, reverse stock splits,
recapitalizations and the like) (a "Significant Holder") (or a representative of
any Significant Holder) to visit and inspect any of the properties of the
Company, including its books of account and other records (and make copies

                                         -14-

<PAGE>



     (b)   The provisions of Section 2.2 and this Section 2.3 shall not be in
limitation of any rights which any Holder or Significant Holder may have with
respect to the books and records of the Company and its subsidiaries, or to
inspect their properties or discuss their affairs, finances and accounts, under
the laws of the jurisdictions in which they are incorporated.

     2.4   ATTENDANCE AT BOARD MEETINGS.  So long as Foster City Partners
("Foster") owns at least an aggregate of 1,000,000 shares of Series A Preferred,
and so long as Foster does not have a representative on the Board of Directors
of the Company, Foster shall receive from the Company notices of all meetings of
the Board of Directors, including without limitation telephonic meetings, and
Foster shall receive, with such limitations provided herein, any materials
distributed for such meeting, and may send one representative to such meetings,
PROVIDED, HOWEVER, that the Company may require as a condition precedent that
such representative proposing to attend any meeting of the Board of Directors
shall agree to hold in confidence and trust and to act in a fiduciary manner
with respect to all information so received during such meetings and may require
that such representative sign a confidentiality agreement with the Company; and,
PROVIDED, FURTHER, that the Company reserves the right not to provide
information and to exclude such representative from any meeting or portion
thereof if attendance at such meeting by such representative or dissemination of
any information at such meeting to such representative would, in the good faith
judgment of the Board of Directors, result in disclosure of trade secrets to
such representative, would compromise or adversely affect the attorney-client
privilege between the Company and its counsel, or would, in the good faith
judgment of the Board of Directors, result in a conflict of interest situation.
If such representative in his or her good faith judgment believes that an item
to be discussed by the Board of Directors would result in any conflict of
interest, such representative shall promptly bring such conflict to the
attention of the Chairman of the Board.  In no event shall any provision of this
paragraph waive any obligation of confidentiality to the Company owed by any
such representative or Foster.

     2.5   TERMINATION OF COVENANTS.  The covenants set forth in Section 2.1,
Section 2.3 and Section 2.4 shall terminate and be of no further force or effect
after the closing date of the Initial Public Offering.

     2.6   CONFIDENTIAL INFORMATION, ETC.  Each Stockholder agrees that all
information received by it pursuant to this Section 2, and any other information
relating to the Company's technology, processes or formulas that is disclosed by
the Company to any Stockholder in writing and is marked "Confidential," shall be
considered confidential information.  Each Stockholder further agrees that it
shall hold all such confidential information in confidence and shall not
disclose any such confidential information to any third party other than its
counsel or accountants nor shall such Stockholder use such confidential
information for any purpose other than evaluation of such Stockholder's
investment in the Company; provided, however, that the foregoing obligation to
hold in confidence and not to disclose confidential information shall not apply
to any such


                                         -15-

<PAGE>


information that (a) was known to the public prior to disclosure by the Company,
(b) becomes known to the public through no fault of such Stockholder, (c) is
disclosed to such Stockholder on a non-confidential basis by a third party
having a legal right to make such disclosure or (d) is independently developed
by such Stockholder.

                                      SECTION 3.

                               RIGHTS OF FIRST REFUSAL


     3.1   RIGHT OF FIRST REFUSAL ON COMPANY ISSUANCES.

     (a)   The Company hereby grants to each Stockholder the right of first
refusal to purchase its Pro Rata Share (defined below) of all (or any part) of
New Securities (defined below) that the Company may from time to time propose to
sell and issue.  Such Stockholder's "Pro Rata Share," for purposes of this
Section 3, is the ratio of the number of shares of Common Stock (assuming
conversion of all shares of Series A Preferred, Series B Preferred and Series C
Preferred) then held by such Stockholder to the total number of shares of Common
Stock then outstanding (assuming conversion of all shares of Series A Preferred,
Series B Preferred and Series C Preferred).  This right of first refusal shall
be subject to the following provisions:

     (b)   "New Securities" shall mean any Common Stock or Preferred Stock of
the Company, whether now authorized or not, and rights, options, or warrants to
purchase said Common Stock or Preferred Stock, and securities of any type
whatsoever that are, or may become, convertible into or exchangeable for said
Common Stock or Preferred Stock; provided, however, that "New Securities" does
not include (i) securities issuable upon conversion of or with respect to Series
A Preferred Stock, Series B Preferred Stock, Series C Preferred or any future
series of preferred stock; (ii) shares of the Company's Common Stock (or related
options) issued to officers, directors, employees of and/or consultants to the
Company pursuant to plans or agreements as approved by the Company's Board of
Directors; (iii) shares of the Company's Common Stock or Preferred Stock issued
in connection with any stock split, stock dividend, or recapitalization by the
Company; (iv) securities issued in connection with any equipment leasing,
technology licensing, corporate partnering, strategic alliance, acquisition,
merger, purchase of assets or similar transaction as approved by the Company's
Board of Directors; and (v) shares of the Company's Common Stock issued or
issuable as a result of any antidilution adjustment provided for in the
Company's Certificate of Incorporation as in effect at the time of such
issuance.

     (c)   In the event that the Company proposes to undertake an issuance of
New Securities, it shall give each Stockholder written notice of its intention,
describing the type of New Securities, the price and the general terms upon
which the Company proposes to issue the same.  Each Stockholder shall have
twenty (20) business days from the date of receipt of any such notice to agree
to purchase some or all of his Pro Rata Share of such New Securities for the
price and upon the general terms specified in the notice by giving


                                         -16-

<PAGE>


written notice to the Company and stating therein the quantity of New Securities
to be purchased.  Each Stockholder shall have a right of over-allotment such
that if any Stockholder fails to exercise his right hereunder to purchase his
Pro Rata Share of New Securities, the other Stockholders may purchase the
non-purchasing Stockholder's portion on a pro rata basis, within fifteen (15)
business days from the date such non-purchasing Stockholder fails to exercise
his right hereunder to purchase his Pro Rata Share of New Securities.

     (d)   In the event that the Stockholders fail to exercise in full the
right of first refusal within said twenty (20) plus fifteen (15) business day
period, the Company shall have one hundred twenty (120) days thereafter to sell
(or enter into an agreement pursuant to which the sale of New Securities covered
thereby shall be closed, if at all, within one hundred twenty (120) days from
the date of said agreement) the New Securities respecting which the
Stockholders' rights were not exercised, at a price and upon general terms no
more favorable to the purchasers thereof than specified in the Company's notice.
In the event the Company has not sold the New Securities within said one hundred
twenty (120) day period (or sold and issued New Securities in accordance with
the foregoing within one hundred twenty (120) days from the date of said
agreement), the Company shall not thereafter issue or sell any New Securities,
without first offering such securities to the Stockholders in the manner
provided above.

     (e)   The right of first refusal granted under this Section 3. 1 shall not
apply to and shall expire upon the closing of the Company's Initial Public
Offering.

     (f)   The rights granted pursuant to this Section 3.1 may be assigned by
the Stockholders (or by any permitted transferee of any such rights) so long as
(i) the Company is given notice of any such assignment within a reasonable time
after the date the same is effected and (ii) the transferee shall have acquired
(or, together with such transferee's Affiliates, after the acquisition shall
then beneficially own) at least 250,000 shares of Registrable Securities
(including shares of Series A Preferred, Series B Preferred and Series C
Preferred prior to conversion into Registrable Securities) in a private
transaction.

                                      SECTION 4.

unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic benefit of this Agreement to any party.

be amended or terminated and the observance of any term of this Agreement may be
waived (either generally or in a particular instance and either retroactively or
prospectively) with the written consent of (i) the Company and (ii) the holders
of at least a majority of the then outstanding shares of Registrable Securities,
excluding from the determination of such a majority in clause (ii) (both in
determining the total number of such shares outstanding and the number of such
shares consenting or not consenting) all shares previously disposed of by such
holders pursuant to one or more registration statements under the Securities Act
or pursuant to Rule 144.  Any amendment, termination or waiver effected in
accordance with this section shall be binding upon the Stockholders, each of

"Amendment") is made as of the 22nd day of February, 1997 (the "Effective
Date"), by and among VISTA MEDICAL TECHNOLOGIES, INC., a Delaware corporation
(the "Company"), HEARTPORT, INC., a Delaware corporation (the "Warrant Holder")
and the Stockholders listed on Exhibit "A" hereto, each of which is herein
referred to as a "Stockholder."

                                 R E C I T A L S

     WHEREAS, the Company and certain of the Stockholders are parties to a
certain Amended and Restated Investors' Rights Agreement dated as of
November 27, 1996, as amended through the date hereof (the "Agreement"),
pursuant to which certain of the Stockholders possess registration rights,
information rights, rights of first refusal and other rights, and the Company is
obligated thereunder;

     WHEREAS, the Company has issued a warrant ("Warrant") to Warrant Holder to
purchase up to 133,333 shares of Common Stock of the Company; and

     WHEREAS, the Stockholders, the Company and the Warrant Holder hereby intend
that this Amendment shall amend the Agreement so that the obligations of the
Company to register Common Stock issuable to Warrant Holder upon exercise of the
Warrant are covered by the Agreement.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.   Section 1.2 entitled "Certain Definitions" is hereby amended to add
the following definition:

     "WARRANT: shall mean that certain Warrant dated February 22, 1997 issued by

upon exercise of the Warrant and (v) any Common Stock of the Company issued as
(or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for or in replacement of, the shares referenced in (i), (ii),
(iii) and (iv) above, excluding in all cases, however, any Registrable
Securities sold by a person in a transaction in which his rights under this
Section 1 are not assigned and any Registrable Securities as to which the
registration rights granted hereunder have been terminated pursuant to Section
1.14.

     3.   Section 4.8 is amended in its entirety to read as follows:

          "4.8 APPROVAL OF AMENDMENTS AND WAIVERS.  Any term of this agreement
may be amended or terminated and the observance of any term of this Agreement
may be waived (either generally or in a particular instance and either
retroactively or prospectively) with the written consent of (i) the Company and
(ii) the holders of at least a majority of the then outstanding shares of
Registrable Securities (including for this purpose shares of Series A Preferred,
Series B Preferred and Series C Preferred prior to conversion into Registrable
Securities), excluding from the determination of such a majority in clause (ii)
(both in determining the total number of such shares outstanding and the number
of such shares consenting or not consenting) all shares previously disposed of
by such holders pursuant to one or more registration statements under the
Securities Act or pursuant to Rule 144.  Any amendment, termination or waiver
effected in accordance with this section shall be binding upon the Stockholders,
each of their transferees and the Company.  Each Stockholder acknowledges that
by the operation of this Section the holders of a majority of the outstanding
Registrable Securities as aforesaid may have the right and power to diminish or
eliminate all rights of such Stockholders under this Agreement."

     4.   Section 1.15 is amended to replace the word "Investor" with the word
"Holder" in the second line of the last paragraph of Section 1.15.  Section
2.3(a) is amended to replace the word "Investor" in line 1 with the word
"Stockholder."  Section 2.3(b) is amended to replace the word "Holder" the first

4.7 are each hereby amended to replace all references to the words
"stockholders" and "Stockholders" with the words "Holder" and "Holders",
respectively.

     5.   By signature below, Warrant Holder agrees that it will have and comply
with all of the rights and obligations of a Holder under the Agreement.  All
other terms and provisions of the Agreement remain in full force and effect.

               INVESTMENT REPRESENTATIONS AND REGISTRATION RIGHTS


                                December 13, 1996


Urohealth Systems, Inc.
Five Civic Plaza, Suite 100
Newport Beach, California 92660

Ladies and Gentlemen:

     Reference is made to that certain License Agreement dated as of December
13, 1996 (the "AGREEMENT") between Urohealth Systems, Inc., a Delaware
corporation (the "COMPANY"), and Vista Medical Technologies, Inc., a Delaware
corporation ("VISTA").  Pursuant to the Agreement, Vista will license certain
technology to the Company in exchange for, among other consideration, shares of
Common Stock of the Company (the "STOCK").

     Vista represents and warrants to, and agrees with, the Company as follows:

     1.   Vista has been advised that the issuance of the Stock to Vista
pursuant to the Agreement will not be registered with the Securities and
Exchange Commission (the "COMMISSION") under the Securities Act of 1933, as
amended ("ACT"), and, therefore, the Stock will constitute "restricted
securities" within the meaning of Rule 144 promulgated under the Act.  Vista has
been advised that dispositions of the Stock, under current law, may only be made
in accordance with the provisions of Rule 144 under the Act, pursuant to an
effective registration statement under the Act or pursuant to an exemption
provided thereunder.  Vista understands that the provisions of Rule 144
currently restrict sales of the Stock during the two year period after the
issuance of the Stock, and permit sales, in general, only while the Company is
subject to the requirements to file, and is filing, periodic reports under
Section 13 or 15(d) of the Securities Exchange Act of 1934, in brokers'
transactions (or transactions directly with a market maker) where the aggregate
number of shares sold at any time, together with all sales of restricted shares
of Common Stock of the Company sold for Vista's account during the preceding
three month period, does not exceed the greater of (i) one percent of the number
of shares of Common Stock of the Company outstanding or (ii) the average weekly
volume of trading in shares of Common Stock of the Company on all national
securities exchanges, and/or reported through the automated quotation system of
a registered securities association, during the four week period preceding any
such sale.

     2.   Vista understands that except as provided in paragraph 4 below, the
Company is under no obligation to register the sale, transfer or other
disposition of the shares of the Stock that Vista will receive under the
Agreement or to take any other action necessary in order to obtain compliance
with an exemption from registration that may be available.

     3.   Vista understands that stop transfer instructions may be given to the
Company's transfer agent with respect to the Stock and that there will be placed
on the certificates for such shares, or any substitution therefor, a legend to
the foregoing effect.

     4.   Vista understands that, pursuant to the terms and conditions of the
Agreement, the Company hereby grants to Vista certain rights with respect to the
registration of the Stock which it will receive under the Agreement, which
rights are as follows:

          (a)  PARTICIPATION REGISTRATION.  Subject to paragraph (b) of this
Section 4, if the Company shall, at any time after the date hereof and on or
prior to 24 months following the date on which the Stock is issued under the
Agreement (or such earlier date on which Vista is then able to dispose of the
Stock pursuant to Rule 144 under the Act), propose the registration under the
Act of an offering of shares of Common Stock of the Company, the Company shall
give written notice as promptly as possible of such proposed registration to
Vista and will use reasonable efforts to cause to be included in the
registration statement such number of shares of the Stock owned by Vista as it
shall request (the "REQUESTED SHARES"), within 15 days after the giving of such
notice, such shares to be included, upon the same terms (including the method of
distribution) of any such offer; provided that (A) the Company shall not be
required to give notice or include the Requested Shares in any such registration
if the proposed registration is not to be made on Form S-1 or Form S-3 (or a
form similar thereto) or is primarily (i) a registration of a stock option or
compensation plan or of securities issued or issuable pursuant to any such plan,
or (ii) a registration of securities proposed to be issued in exchange for
securities or assets of, or in connection with a merger or consolidation with,
another corporation; and (B) the Company may, in its sole discretion and without
the consent of Vista, withdraw such registration statement and abandon the
proposed offering in which Vista had requested to participate.

          (b)  REDUCTION.  Vista acknowledges and agrees that the rights granted
hereunder are subject to the existing rights of parties to that certain
Registration Rights Agreement, dated May 13, 1996, among the Company and the
stockholders identified therein (the "EXISTING REGISTRATION RIGHTS AGREEMENT"),
and the rights granted hereunder shall in no event exceed the rights of
Miscellaneous Shares (as defined in the Existing Registration Rights Agreement)
under such agreement.  In the event that the Company is advised by its
investment banking firm that, in its reasonable opinion, the number of Requested
Shares will interfere with the orderly sale and distribution of the shares of
Common Stock being offered by the Company or the holders under the Existing
Registration Rights Agreement, the Company shall not be required to include the
Requested Shares in the registration.

          (c)  INDEMNIFICATION.  The Company shall provide Vista with the usual
and customary indemnification in connection with any registration pursuant
hereto.

          (d)  REGISTRATION EXPENSES.  The Company shall bear all reasonable
costs and expenses incurred with any registration pursuant to paragraph (a)
above, except that Vista will pay for the fees and expenses of its counsel and
its pro rata portion of the

underwriters' discounts, commissions or other compensation and any applicable
transfer taxes.

          (e)  ASSIGNMENT.  Vista shall have the right to assign the rights
granted to it hereunder in connection with the sale or transfer of all or a
portion of the Stock; provided, that such transferee receives at least 25% of
the Stock issued to Vista under the License Agreement.

          (f)  SUBSEQUENT REGISTRATION RIGHTS.  From and after the date of this
Agreement, the Company will not, without the prior written consent of Vista,
enter into any agreement with any holder or prospective holder of securities of
the Company which would allow such holder or prospective holder to include such
securities in a registration filed under Section 4(a) or otherwise unless, under
the terms of such agreement, such holder or prospective holder may include such
securities in any such registration only to the extent that the inclusion of
such holder's securities will not reduce the amount of the Stock which is
included.  Notwithstanding the provisions of this subparagraph (f) to the
contrary, the Company shall only be restricted in granting rights to a holder or
prospective holder which rights would give such holder priority over the
registration rights granted Vista hereunder and nothing herein shall prevent the
Company from granting demand registration rights which have a priority in
connection with any demand to a holder or prospective holder (excluding any
holder or prospective holder who is granted those rights in connection with a
joint venture between such holder and the Company or other similar corporate
partnering arrangement).

     Vista acknowledges that it has carefully read this letter and discussed its
requirements and other applicable limitations upon the sale, transfer or other
disposition of the shares of Common Stock to be acquired by it under the
Agreement, to the extent it felt necessary, with its counsel.

                    Very truly yours,

                                 CONSULTING AGREEMENT


    This is an agreement ("Consulting Agreement") effective as of September 15,

1.  Collateral Agreements:

                           PROFESSIONAL SERVICES AGREEMENT
                       (CLINICAL ADVISORY BOARD AND CONSULTING)

    THIS PROFESSIONAL SERVICES AGREEMENT ("Agreement") is entered into as of
___________, 199__ ("Effective Date"), by and between ___________________
("Advisor") and Vista Medical Technologies, Inc., a California corporation ("the
"Company").  In consideration of the retention of Advisor as a clinical and
scientific advisor and consultant to the Company, and of the compensation
received by Advisor from the Company, the Company and Advisor hereby agree as
follows:

    1.   DESCRIPTION OF SERVICES.  

         (a)  CLINICAL ADVISORY BOARD AND CONSULTING.  The Company hereby
retains Advisor and Advisor hereby agrees to serve as a member of the Company's
Clinical Advisory Board and as a consultant for the term of this Agreement. 
Advisor will advise the Company as an independent contractor in the medical
applications of visualization technologies in cardiothoracic endosurgery.  The
services to be rendered as a consultant are set forth on SCHEDULE 1 to this
Agreement.

         (b)  EXCLUSIVITY.  Advisor will work exclusively with the Company in
the area of visualization technologies for cardiothoracic surgery.  Advisor
represents that all of his/her current consulting or advisory obligations are
listed on EXHIBIT A, and agrees that he/she will not enter into any written or
oral agreement with any entity, company or person which is or may be (or the
potential to be) a competitor of the Company relating to his/her consulting or
advisory services unless the Company is notified of such agreement in advance. 
Advisor understands that while he/she is an advisor to the Company he/she is not
to breach any obligation of confidentiality that he/she has to others.  
  
    2.   TIME COMMITMENT.  

         (a)  CLINICAL ADVISORY BOARD.  The time commitment of Advisor will
include a minimum of two (2) formal, full-day Clinical Advisory Board meetings
per year, at the Company's request, unless the Company and Advisor otherwise
mutually agree to extend the length or number of such meetings.  Advisor also
will from time to time provide scientific counsel on a reasonable basis to
personnel working on projects on behalf of the Company; such counsel, which will
consist primarily of advice on interpreting scientific or clinical data and
planning experiments or trials, will be at Advisor's convenience and will be
limited to matters that are compatible with Advisor's faculty or other
employment responsibilities and other oral and written agreements to which
Advisor is a party.

<PAGE>

         (b)  CONSULTING.  The time commitment as a consultant will be set
forth on SCHEDULE 1.  

    3.   COMPENSATION.  

         (a)  CASH COMPENSATION.  For all services rendered hereunder, Advisor
will be compensated at the rate of U.S. $_______.00 per ________________,
payable as follows:                                                  .  

         (b)  OTHER COMPENSATION.  At the Board of Directors' meeting
immediately following the execution of this Agreement, Advisor will be granted
such additional compensation as set forth on attached EXHIBIT B.

         (c)  TRAVEL EXPENSES AND OTHER DIRECT EXPENSES.  Advisor will be
reimbursed for reasonable travel expenses incurred in performing his/her
advisory obligations, as authorized by the Company's expense reimbursement
policy.  The Company will reimburse Advisor for all other reasonable direct
expenses actually incurred which are incidental to the services performed
hereunder and which have been approved in writing in advance by the Company. 
Advisor will provide the Company with invoices detailing the expenses and
reimbursements which Advisor believes are due under this Agreement.  Invoices
should specify the period for which reimbursement is claimed.  Travel costs and
other expenses claimed must be itemized.  All invoices must be substantiated by
receipts for transportation and lodging and all other items for expenses
amounting to more than $25.00 where receipts are normally issued.  The Company
agrees to pay approved invoices within forty-five (45) days of receipt.

         (d)  SOLE COMPENSATION.  The foregoing fees, other compensation and
reimbursement of expenses are Advisor's sole compensation for rendering services
to the Company.

    4.   INDEPENDENT CONTRACTOR.  Advisor's relationship with the Company will
be that of an independent contractor and nothing in this Agreement will be
construed to create an employer-employee relationship between the Company and
Advisor.  Advisor has no authority to act on behalf of or to enter into any
contract, incur any liability or make any representation on behalf of the
Company.  The Company agrees that during the term of this Agreement, or any
extension or renewal thereof, Advisor may be employed by other persons, firms or
corporations; PROVIDED, HOWEVER, that the provisions of this Agreement will be
strictly observed by Advisor with respect to such other persons, firms, or
corporations.  Since Advisor will not be an employee of the Company, it is
understood that Advisor will not be entitled to any of the benefits under the
Company's retirement or group insurance plans or any other employee benefits. 
Advisor is solely responsible for all taxes, withholdings and other similar U.
S. or international statutory obligations, including, without limitation,
Workers Compensation Insurance, Social 


                                         -2-


<PAGE>

Security, federal, state or any other employee payroll taxes; and Advisor agrees
to defend, indemnify and hold the Company harmless from any and all claims made
by any entity on account of an alleged failure by Advisor to satisfy any such
tax or withholding obligations.  In the performance of all services hereunder,
Advisor will comply with all applicable laws and regulations.  

    5.   NO CONFLICT WITH EXISTING AGREEMENTS.  The Company hereby acknowledges
that it does not desire to acquire from Advisor any secret or confidential know-
how or information which Advisor may have acquired from others.  Accordingly,
Advisor represents and warrants that Advisor is free to divulge to the Company,
without any obligation to, or violation of any right of others, any and all
information, practice or techniques which Advisor will describe, demonstrate,
divulge or in any other manner make known to the Company during Advisor's
performance of services hereunder. 

    6.   ADVISOR INVENTIONS.  Advisor will promptly and fully disclose and
assign to the Company all Inventions made by Advisor (either alone or jointly
with others) resulting from or arising out of services hereunder.  All such
Inventions will be the sole property of the Company.  Advisor represents and
warrants that Advisor has no obligations to any third party which prohibit or
restrict the right to assign to the Company exclusive right, title and interest
in and to any and all Inventions made by Advisor resulting from or arising out
of services hereunder.  Advisor agrees to assist the Company at Company's
expense, and to execute any further documents that are necessary or appropriate,
to obtain, maintain, or enforce patents on any Inventions described above in the
United States and elsewhere.  As used in this Agreement, the term "Inventions"
means any and all inventions, discoveries, designs, formulas, technology,
improvements, trade secrets, results of experiments or clinical trials,
processes, techniques and know-how, whether or not patentable, and whether or
not related to the Company's business, which RESULT FROM OR ARISE OUT OF
SERVICES RENDERED TO THE COMPANY AND are invented, conceived, discovered,
developed or reduced to practice by Advisor, either alone or jointly with
others.

    7.   NON-DISCLOSURE AND NON-USE.  The parties hereto acknowledge that
during the course of services to the Company pursuant to this Agreement it will
become necessary or desirable for the Company to disclose to Advisor a
substantial amount of the Company Proprietary Information.  "Proprietary
Information" is information that was or will be developed, created, or
discovered by or on behalf of the Company, or which becomes or will become known
by, or was or is conveyed to the Company which has commercial value in the
Company's business.  "Proprietary Information" includes, but is not limited to,
information about operations and maintenance, results of experiments or clinical
trials, trade secrets, computer programs, design, technology, ideas, know-how,
processes, formulas, compositions, data, techniques, improvements, inventions
(whether patentable or not), works of authorship, business and product
development plans, customers and other information concerning the Company's
actual or anticipated business, research or development, or which is received in
confidence by or for the 


                                         -3-


<PAGE>

Company from any other person.  "Proprietary Information" does not include
information that Advisor demonstrates to the Company's satisfaction, by written
evidence, is in the public domain by reason of prior publication not directly or
indirectly resulting from any act or omission of Advisor.  Advisor fully
understands that the maintenance of such Proprietary Information in strict
confidence and the confinement of its use to the Company is of vital importance
to the Company.  Advisor agrees that the Proprietary Information divulged to
Advisor by the Company or which Advisor acquires in connection with or as a
result of services hereunder will be regarded by Advisor as confidential. 
Advisor will not use, nor will Advisor disclose, any Proprietary Information to
any person either during or after the period of this Agreement, except to those
employees of Advisor or the Company as may be necessary in the regular course of
Advisor's duties hereunder, or except as otherwise authorized in writing by the
President of the Company.

    8.   COMPANY MATERIALS.  Advisor recognizes that all the Company Materials
made or received by Advisor during the period of this Agreement are and will be
the exclusive property of the Company, and Advisor will keep the same at all
times in Advisor's custody and subject to Advisor's control, and will surrender
the same to the Company immediately upon request of the Company.  "Company
Materials" are documents or other media or tangible items that contain or embody
Proprietary Information or any other information concerning the business,
operations, or plans of the Company, whether such documents have been prepared
by Advisor or by others.  "Company Materials" include, but are not limited to,
blueprints, drawings, photographs, charts, graphs, notebooks, customer lists,
computer disks, tapes or printouts, sound recordings and other printed,
typewritten, or handwritten documents, as well as samples, prototypes, models,
products and the like.

    9.   COMPANY PROPERTY.  All Proprietary Information and all title, patents,
patent rights, copyrights, mask work rights, trade secret rights, and other
intellectual property and rights anywhere in the world (collectively "Rights")
in connection therewith will be the sole property of the Company.  Advisor
hereby assigns to the Company any Rights Advisor may have or acquire in such
Proprietary Information.  At all times, both during the term of this Agreement
and after its termination, Advisor will keep in confidence and trust and will
not use or disclose any Proprietary Information without the prior written
consent of an officer of the Company appropriate in the ordinary course of
performing the services under this Agreement.  

    10.  TERM AND TERMINATION.  The initial term of this Agreement will be for
a one (1) year period following the Effective Date; and thereafter will renew
automatically for additional one (1)-year periods unless terminated by either
party at least 90 days prior to an anniversary date.  At the Company's option,
this Agreement will also terminate upon notice to Advisor in the event of
Advisor's inability for any reason to perform Advisor's services.   Upon
termination of this Agreement, the Company's obligation to pay any compensation,
except for services or expenses already accrued or incurred under Section 2,
will immediately cease and terminate.  Termination of this 


                                         -4-


<PAGE>

Agreement for any reason will not affect Advisor's obligations under Sections 4,
6, 7, 8, 9 and 10.

    11.  REMEDIES.  Advisor acknowledges and agrees that a breach of this
Agreement will result in immediate, irreparable and continuing damage to the
Company for which there will be no adequate remedy at law; and agrees that in
the event of any such breach or violation or any threatened or intended breach
or violation of this Agreement, the Company and its successors and assigns will
be entitled to temporary, preliminary and permanent injunctive relief and/or
restraining orders enjoining and restraining such breach or violation or such
threatened or intended breach or violation and/or other equitable relief
(without needing to post any bond or other security) in addition to such other
and further relief as may be proper.  

    12.  AMENDMENTS AND WAIVERS.  This Agreement may be modified, amended or
supplemented only by a written instrument duly executed by Advisor and the
President of the Company.  No term or condition or the breach thereof will be
deemed waived, unless it is waived in writing and signed by the party against
whom the waiver is claimed.  Any waiver or breach of any term or condition will
not be deemed to be a waiver of any preceding or succeeding breach of the same
or any other term or condition.  The failure of any party to insist upon strict
performance of any term or condition hereunder will not constitute a waiver of
such party's right to demand strict compliance therewith in the future.

    13.  NOTICES.  All payments, notices, requests, demands and other
communications required or permitted hereunder will be in writing and will be
delivered personally (which will include delivery by courier or overnight
delivery service) or sent by first class mail, postage prepaid, or sent by
telecopier or other similar facsimile transmission to the parties at their

                      PATENT AND INVENTION ASSIGNMENT AGREEMENT



    Agreement made and entered into as of the 18th day of December, 1991
between American Surgical Technologies Corporation, a Delaware corporation (the
"Company") and Harry R. McKinley (the "Consultant") and McKinley Optics, Inc., a
Massachusetts corporation ("MOI").

    The Consultant and MOI have, by a License and Development Agreement of even
date herewith (the "License and Development Agreement") granted the Company a
license relating to a stereoscopic objective lens and, by a Consulting Agreement
of even date herewith (the "Consulting Agreement"), the Company has engaged the
Consultant to provide certain consulting and development services.  In
consideration of the foregoing, and for other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged, the parties agree as
follows:

    1.   AGREEMENT NOT TO COMPETE WITH THE COMPANY:

         So long as the license granted pursuant to the License and Development
Agreement is exclusive, neither the Consultant nor MOI shall, on their own
behalf, or as owner, manager, stockholder, consultant, director, officer or
employee of any business entity, participate in the development or provision of
medical products or services which the Consultant and MOI know or should know
are directly competitive with products or services developed or provided, or
under development by the Company or consistent with the Company's development
plan, without the prior written authorization of the Company; provided, however,
that the Consultant may, without the Company's prior written authorization, own
up to one percent (1%) of the issued and outstanding securities of any publicly
held corporation.

    The Consultant and MOI recognize that the Company is developing highly
specialized products and services in competition with other business entities
throughout the United States and the world, which products and services are
designed to compete in regional, nation-wide and world-wide markets.  In light
of the competitive nature of the Company's products and services, the Consultant
agrees that the restrictions contained in this Section 1 cannot be limited to
any geographic area.

    2.   UNAUTHORIZED DISCLOSURE OF CONFIDENTIAL INFORMATION:
Except as permitted hereunder or under the License and Development Agreement,
neither the Consultant nor MOI shall, directly or indirectly, use any
Confidential Information (as hereinafter defined) other than by and for the
benefit of the Company, or disclose to anyone outside of the Company any such
Confidential Information.  The term "Confidential Information" as used
throughout this Agreement shall mean all trade

<PAGE>

secrets, proprietary information and other data or information (and any tangible
evidence, record or representation thereof), whether prepared, conceived or
developed by an employee or consultant of the Company or received by the Company
from an outside source, which is in the possession of the Company (whether or
not the property of the Company), which in any way relates to the present or
future business of the Company, which is maintained in confidence by the
Company, or which might permit the Company or its customers to obtain a
competitive advantage over competitors who do not have access to such trade
secrets, proprietary information, or other data or information.  Without
limiting the generality of the foregoing, Confidential Information shall
include:

         (a)  any idea, improvement, invention, innovation, process, procedure,
development, technical data, design, drawing, prototype, formula, device,
pattern, concept, computer program, software, firmware, source code, object
code, schematic, model, diagram, flow chart, user manual, training or service
manual, product specification, plan for a new or revised product or service,
item or compilation of information, or work in process, and any and all
revisions and improvements relating to any of the foregoing (in each case
whether or not reduced to tangible form); and

         (b)  the name of any customer, employee, prospective customer,
supplier, sales agent or consultant, any other customer or prospective customer
information, any sale plan, marketing material, plan or survey, business plan or
opportunity, product or service development plan or specification, business
proposal, financial record, business record or other record or information
relating to the present or proposed business of the Company or any customer.

         Notwithstanding the foregoing, the term Confidential Information shall
not apply to information which the Company has voluntarily disclosed to the
public without restriction, or which has otherwise lawfully entered the public
domain.

         MOI and the Consultant understand that the Company from time to time
has in its possession information which is claimed by customers and others to be
proprietary and which the Company has agreed to keep confidential.  MOI and the
Consultant agree that all such information shall be Confidential Information for
purposes of this Agreement.

    3.   ALL INVENTIONS THE PROPERTY OF THE COMPANY:  The Consultant agrees
that all originals and all copies of all manuscripts, drawings, designs,
prototypes, prints, manuals, diagrams, letters, notes, notebooks, reports,
models and all other materials containing, representing, evidencing, recording

Company immediately upon production or development of the same and at any time
upon request.

    5.   CONSULTANT'S OBLIGATION TO COOPERATE:  The Consultant will, at any
time during his engagement with the Company or after it terminates, on request
of the Company, execute all documents and perform all lawful acts which the
Company considers necessary or advisable to secure its rights hereunder an to
carry out the intent of this Agreement.  It is understood that reasonable
out-of-pocket expenses of the Consultant's assistance incurred at the request of
the Company will be reimbursed by the Company.  If the Consultant is required or
directed by the Company to perform work not otherwise within the scope of his
duties under the Consulting Agreement, the Company agrees to compensate the
Consultant for such work on the basis of a reasonable hourly rate, which shall
be mutually agreed upon by the Consultant and the Company.

    6.   RETURN OF PROPERTY:  If this Consulting Agreement terminates or
expires, or at any other time upon request of the Company, the Consultant shall

                                         -3-

<PAGE>

         If requested to do so by the Company, the Consultant agrees to sign a
Termination Certificate in which he confirms that he has complied with the
requirements of the preceding paragraph and that he is aware that certain
restrictions imposed upon him by this Agreement continue after termination of
his employment.  The Consultant understands, however, that his rights and
obligations under this Agreement will continue even if he does not sign a
Termination Certificate.

    7.   MISCELLANEOUS PROVISIONS:  This Agreement contains the entire and only
agreement between the Consultant and MOI and the Company respecting the subject
matter hereof, except, to the extent that the Company's ownership of Work

Development Agreement, and no modification, renewal, extension, waiver or
termination of this Agreement or any of the provisions herein contained shall be
binding upon either party unless made in writing and signed by the Consultant,
MOI and an authorized officer of the Company.  In the event of any inconsistency
between this Agreement and any other contract between the Consultant, MOI and
the Company, the provisions of this Agreement shall prevail.

         The obligations of the Consultant and MOI under this Agreement with
respect to confidentiality, non-competition and the assignment of patent and
invention rights shall survive the termination of the Consulting Agreement and
the License and Development Agreement regardless of the manner of or reasons for
such termination, and regardless of whether such termination constitutes a
breach of any other agreement he may have with the Company.  The obligations of
the Consultant and MOI under this Agreement shall be binding upon their
respective successors and assigns, heirs, executors and administrators, and the
provisions of this Agreement shall inure to the benefit of and be binding on the
successors and assigns of the Company.

         If the scope of any provision contained herein is too broad to permit
enforcement of such provision to its full extent, then such provision shall be
enforced to the maximum extent permitted by law, and the parties hereby consent
and agree that such scope may be judicially modified in any proceeding brought
with respect to the enforcement of such provision.  Except as otherwise provided
in the previous sentence, if any provision of this Agreement shall be construed
to be illegal or invalid, the legality or validity of any other provision hereof
shall not be affected thereby, and any illegal or invalid provision of this
Agreement shall be severable, and all other provisions shall remain in full
force and effect.

         The Consultant and MOI recognize that money damages alone would not
adequately compensate the Company in the event of breach by the Consultant of
this Agreement, and the Consultant and MOI therefore agree that, in addition to
all other remedies available to the Company at law or in equity, the Company
shall be entitled to injunctive relief for the enforcement hereof.  Failure by
the Company to insist upon strict

deemed a waiver of such terms, covenants or conditions.

     For the purposes of this Agreement, the following words and phrases shall
have the following meanings:

more fully described in Appendix A attached hereto and made a part hereof.  As
Used herein, the term "Know-How" means all unpatented scientific, engineering,
or other know-how schematic designs, computer programs, code, software,
firmware, technical data or information, all methods, processes and procedures,
all products, formulations and kits and all instruments and apparatus materially
related to the Licensed Products.

     1.4  "Patent Rights" shall mean only those United States patent
applications filed which are set forth in Appendix A or corresponding foreign
patent applications to be filed (hereinafter referred to as the "Patent Rights
Patent Application(s)"), and the United States patents and foreign patents
issuing therefrom (hereinafter referred to as "Patent Rights Patent(s)") and any
continuations, continuations-in part, divisions, reissues or extensions of any
of the foregoing.

     1.5  "Licensed Products" shall mean any endoscope which (a) is designed,
marketed or sold for medical purposes AND (b) incorporates a stereo objective
lens for use in endoscopes of any length, diameter or configuration, as
disclosed in the patent application filed April 16, 1991 by McKinley (a copy of
which is attached hereto).

     1.6  "Licensed Process(es)" shall mean a process(es) for making any item
relating to the above Technology which (a) is covered in whole or in part by a
pending claim contained in a Patent Rights Patent Application, (b) is covered in

mailed by certified mail to Licensor for all monies due and owed to Licensor.
Furthermore, Licensor shall not be obligated to give notice for interest to
begin to accrue.

     3.4  No multiple royalties shall be payable because the Licensed Product(s)

for such  * * * period.  To accept an Offer, the Company must deliver a written
notice to McKinley, MOI or both, as the case may be, prior to the end of the

     6.1  Licensor, at Licensor's sole expense, shall apply for and shall seek
prompt issuance of United States patents based upon the Patent Rights, PROVIDED
that this provision shall not be interpreted to prohibit Licensee from taking
such actions with respect to the Patent Rights if, in the reasonable judgment of
Licensee, Licensor is not diligently fulfilling its obligations under this
subsection 6.1. Unless the licenses granted hereunder have ceased to be
exclusive, the prosecution and maintenance of corresponding foreign Patent
Rights Patents and Patent Rights Applications and all expenses relating thereto,
shall be the responsibility of Licensee, PROVIDED that Licensee shall have no

Applications.  Licensor shall cooperate fully with Licensee in the prosecution
and maintenance of such foreign Patent Rights Patents.

     6.2  Licensor agrees that upon Licensee's request and at Licensee's
expense, it shall promptly make all disclosures, execute all instruments and
documents and perform all acts whatsoever necessary or desirable to vest or

created or contemplated by Sections 2.2 and 2.3 of Article 2 above and by
Article 5 above including any and all applications, writings and documents as

exclusivity maintenance royalties due in accordance with Section 3.1(b) of this
Agreement, Licensor shall have the right to notify Licensee of termination of
exclusivity of the license granted under this Agreement effective  * * *  after
such notice unless Licensee shall pay to Licensor, within the  * * * period, all
such royalties due and payable.  Upon the expiration of the * * *  period, if
Licensee shall not have paid all such monies due and payable, the exclusive
rights, privileges and license granted hereunder shall thereupon immediately

remit payment of exclusivity maintenance royalties, after the second anniversary
of the date of this Agreement, and not before, upon any breach or default of
this Agreement by Licensee, Licensor shall have the right to notify Licensee of
termination of this Agreement effective  * * * after mailing of such notice
unless Licensee shall have cured any breach underlying such notice within the
* * *  period.  Upon the expiration of the * * *  period, if Licensee shall not
have cured such breach, the rights, privileges and license granted hereunder
shall thereupon immediately terminate in full, provided, however, that if there
is a dispute relating to such breach which either party has submitted to
arbitration pursuant to Article 8 below, there shall be no termination prior to
the final decision in the arbitration and the decision reached in the
arbitration shall determine whether a termination may take place.



* * * Confidential Treatment Requested

<PAGE>

     7.3  Licensee shall have the right to terminate this Agreement at any time
upon * * *   prior notice to Licensor, provided that the Licensee shall continue
to pay the license exclusivity maintenance royalty payment according to the
terms of Article 3 above for the * * * in which such termination takes effect
and for the  * * *      following such * * *.  Upon such termination, Licensee
shall have no further rights, whether exclusive or non-exclusive, to the
Licensed Products, the Licensed Process(es) or the Technology hereunder.

     7.4  Upon termination of this Agreement for any reason, Licensee and/or any
sublicensee thereof may sell all Licensed Products, and complete Licensed
Products in the process of manufacture at the time of such termination and sell
the same, provided that Licensee shall pay to Licensor the royalties therefor as
required by Article 3 of this Agreement and shall submit the reports required by
Article 4 hereof on such sales.

     7.5  Upon termination of this Agreement, nothing herein shall be construed
to release either party from any obligation(s) that matured under this Agreement

provisions of Sections 2.5, 2.6, 3.1(c), 4.l, 4.2, 6.2, 10.2, 10.3, Article 11
and 12.4 shall remain in full force and effect.


                   ARTICLE 8 -- ARBITRATION; INJUNCTIVE RELIEF

     8.1  Except as to issues relating to the validity, construction or effect
of any patent licensed hereunder, any and all claims, disputes or controversies
arising under, out of, or in connection with this Agreement, which have not been
resolved by communication between the parties, shall be resolved by final and
binding arbitration in Boston, Massachusetts under the rules of the American
Arbitration Association then obtaining.  The arbitrators shall have no power to
add to, subtract from or modify any of the terms or conditions of this
Agreement.  Any award rendered in such arbitration may be enforced by either
party in either the courts of the Commonwealth of Massachusetts or in the United
States District Court for the District of Massachusetts, to whose jurisdiction
for such purposes Licensor and Licensee each hereby irrevocably consents and
submits.

     8.2  Claims, disputes or controversies concerning the validity,
construction or effect of any patent licensed hereunder shall be resolved in any
court having jurisdiction thereof.

     8.3  In the event that, in any arbitration proceeding, any issue shall

hereunder, the arbitrators shall assume the validity of all claims as set forth
in such patent, and the arbitrators shall not delay the arbitration proceeding
for the purpose of obtaining or permitting either party to obtain judicial
resolution of such issue, unless an order staying such arbitration proceeding
shall be entered by a court of competent jurisdiction.  Neither party shall
raise any issue concerning the validity, construction or effect of any patent

licensed hereunder in any proceeding to enforce any arbitration award hereunder
or in any proceeding otherwise arising out of any such arbitration award.

     8.4  Notwithstanding the foregoing, nothing in this Article 8 shall be
construed to waive any rights or timely performance of any obligations existing
under this Agreement.  Furthermore, nothing in this Article 8 shall be construed
to waive the right of Licensee to obtain, in addition to any and all other
remedies available to it at law or equity, injunctive relief to enforce the
exclusivity of the rights, privileges and license granted to it hereunder.  In
that regard, Licensor acknowledges that any grant or attempted grant by it to
grant to any other person or entity a license or other right to use the
Technology or the Patent Rights for any medical purpose will cause irreparable
damage to Licensee and Licensor agrees that Licensee shall be entitled to
injunctive relief for the event of any such grant or attempted grant.

party regarding any patents within the Patent Rights and shall provide each
other with any available evidence of such infringement.

     9.2  During the term of this Agreement, Licensee shall have the right, but
shall not be obligated, to prosecute at its own expense any infringements of the
Patent Rights and, in furtherance of such right, Licensor hereby agrees that
Licensee may join Licensor as a party plaintiff in any infringement suit,
without expense to Licensor.  The total cost of any infringement action
commenced or defended solely by Licensee shall be borne by Licensee, and
Licensee shall keep any recovery or damages for past infringement derived
therefrom.

     9.3  If within  * * *       after having been notified of any alleged
infringement, Licensee shall not have obtained from the alleged infringer an
agreement to desist and shall not have brought and shall not be prosecuting any
infringement actions, or if Licensee shall notify Licensor at any time prior
thereto of its intention not to bring suit against any alleged infringer, then,
and in those events only, Licensor shall have the right, but shall not be
obligated, to prosecute at its own expense any infringement of the Patent
Rights, and Licensor may, for such purposes, use the name of Licensee as party
plaintiff, and shall pay Licensee's legal fees and expenses related thereto.  No
settlement, consent judgment or other voluntary final disposition of the suit
may be entered into without the consent of Licensee, which consent shall not
unreasonably be withheld.  Licensor shall indemnify Licensee against any order
for costs that may be made against Licensee in such proceedings.

     9.4  If Licensee and Licensor agree to institute suit jointly,   the suit
shall be brought in both of their names, and all expenses and recoveries
(whether by judgment, accord, decree or settlement) shall be borne equally.
Licensee shall exercise control over such suit, including employment of counsel
of its own selection at its own expense.

     9.5  In any infringement suit as either party may institute to enforce the
Patent Rights pursuant to this Agreement, the other party hereto shall, at the
request and expense of the party initiating such suit, cooperate in all respects
and, to the extent possible, have

its employees testify when requested and make available relevant records,
papers, information, samples, specimens, and the like.

     9.6  Licensee, during the exclusive period of this Agreement, shall have
the sole right in accordance with the terms and conditions of this Agreement to
sublicense any alleged infringer under the Patent Rights.

including legal expenses and reasonable attorneys' fees, arising out of any
breach of any or all of the foregoing warranties made by Licensor or Licensee,
as the case may be.

      THIS LICENSE AGREEMENT ("Agreement") is entered into as of the 2nd day of
September 1994, by Allen Newman, an individual, ("Newman" or "Licensor") and
Vista Medical Technologies, Inc., 2752 Loker Avenue West, Carlsbad, California
92008 ("Vista", or "Licensee"), referred to individually as a Party and together
as the Parties.

                                       RECITALS

A.    Newman represents that he has conceived and developed certain technology
and products in the field of procedure specific medical instruments employing
advanced optical technologies ("Visual Instruments") and that, to the best of
his knowledge, he owns rights thereto; and,

B.    Newman and Vista have entered into an employment agreement under which
Newman will be an employee of Vista as a member of Vista's senior management
team with Newman's responsibilities to include, among others, directing the

technologies; and,

C.    Newman and Vista now desire to enter into this License Agreement for
medical instruments utilizing optical technology, as set forth herein.

                                      AGREEMENT

      THEREFORE, the Parties agree as follows:

ARTICLE 1 -- DEFINITIONS

As used herein, the following terms have the meanings indicated.

                                          1


<PAGE>

1.1   "Affiliate" shall mean (i) any other division of Vista, (ii) any company
in which more than fifty percent (50%) of the voting shares or other ownership
interests are owned or controlled, directly or indirectly, by Vista, or (iii)
any company which owns or controls, directly or indirectly, more than 50% of the
voting stock of Vista.

1.2   "Licensed Products" are those identified in Schedule 1.2.

1.3   "Licensee" means Vista Medical Technologies, Inc. and its affiliates.

1.4   "Licensor" means Allen Newman, an individual, and/or Newman Medical Inc.,
a corporation, to the extent that Newman Medical may have any rights to any of
the Licensed Products.

1.5   "Licensor's Technology" shall mean inventions directly related to the
Licensed Products (whether or not patentable), ideas, design concepts,
processes, formulas and know-how owned or controlled by Licensor and used by it
as of the date of this Agreement.  Patents and patent applications are
identified in Schedule 1.5.

1.6   "Licensee's Technology" shall mean inventions (whether or not

envisioned by Article 4.2, below, which approval will not be unreasonably
withheld.


                                          2


<PAGE>

ARTICLE 3 -- VISTA'S UNDERTAKINGS

3.1   Vista intends to develop the Licensed Products at its expense and bring
them to market by appropriate means of distribution according to the time
schedule set forth in Schedule 1.2, Licensed Products.  Provided, however, that
if delays in the regulatory process delay Vista's undertakings, the two year
commitment shall be extended to take into account the effects of such delay.

3.2   Vista has the right in its sole discretion not to develop, to discontinue
to develop, or to discontinue marketing any or all of the Licensed Products at
any time.

3.3   If Vista fails to meet its obligations under 3.1, above, or elects to
discontinue as provided by 3.2, above, then Newman's sole rights will be any
applicable reversion rights set forth in Article 4.1, below.

3.4   Vista will, at its expense, pursue an appropriate level of patent
protection for the Licensed Products, under Newman's name as inventor, but
assigned to Vista.

ARTICLE 4 -- REVERSION RIGHTS; ASSIGNMENT RIGHTS

4.1   If Newman becomes entitled to reversion rights to any Licensed Product
pursuant to 3.3, above, then upon written request by Newman to Vista, Vista will
transfer its rights to such Licensed Product and directly related Licensor's
Technology to Newman, subject to any rights that may have been granted pursuant
to Article 4.2, below, prior to Newman's right to reversion and subject further
to any rights that Vista reasonably may need to retain, on a non-exclusive basis
with Newman or any of his assigns, in order to develop or market Licensed
Products not reverting to Newman.  If at the time of such reversion, Newman also
wishes to acquire rights to Licensee's Technology and other Visual Instrument
technology and products developed by Vista, Vista and Newman will negotiate in
good faith arrangements for such rights including, among other provisions,


                                          3


<PAGE>

compensation to Vista for recovering its development costs for such Licensee's
Technology and other technology and products.

4.2   If Vista elects to sell or transfer its rights to the Licensor's
Technology or to a Licensed Product, then it may do so provided that Newman's
rights are protected in the transfer (i.e., the transferee accepts the principal
terms of this Licensing Agreement as a condition of the sale or transfer).

5.    ROYALTIES

5.1   Royalties will be paid by Vista as a      * * *         of the Licensed
      Products.  Royalty rates (R) will be based on the       * * *
      (G) of the Licensed Products as follows:

      a.     For the                             * * *
             (    * * *            ): R =    * * *      where R and G are
             in percent (%).  If G drops below ***, no royalty will be paid.

      b.     For the                    * * *
             ***  : R = *** if G > ***; or R = *** if G < ***.

When total royalties due for all Licensed Products reach    * * * in any
calendar year, then the royalty rate for the Licensed Products identified in
5.1(a) will change to R =    * * *     for subsequent sales until the end of
that year.

The above     * * *        are based upon sale by Vista direct to end users.  In
the event of indirect sales (such as to Original Equipment Manufacturers,
stocking distributors, and similar value-adding resellers) the gross margin
levels specified in the above formulae shall be reduced by       * * *
(for example,     * * *


* * * Confidential Treatment Requested


                                          4


<PAGE>

5.3   (a)    Under this Agreement, each Licensed Product will be considered as
sold when finally paid for by Vista's customer(s), but royalties paid on each
Licensed Product which is not finally accepted, or for which acceptance is
revoked, or is otherwise rejected, by Licensee's customer(s), shall be credited
against royalties payable hereunder.

      (b)    The foregoing royalties shall be payable    * * *  on or before
the    * * *   days of        * * *         of each year during the term of this
Agreement.

5.4   LOAN AGREEMENT.  Vista immediately upon the signing by both Parties of
this Agreement will loan to Newman an advance in the amount of  * * *  secured
against royalties that may become due.  A copy of the loan agreement is attached
hereto, identified as Attachment 5.4, Promissory Note.  Such loan agreement
shall survive termination of this License Agreement.  The first   * * * of all
royalties due from Vista under the terms of this License Agreement shall be
applied toward repayment of the Promissory Note.

5.5   TERMINATION OF ROYALTY OBLIGATIONS; PAID-UP LICENSE.  Vista is obligated
to pay royalties as provided herein on patented Licensed Products only while a
valid patent is in effect.  For all other Licensed Products, Vista's royalty
obligation shall cease  * * *   years after Vista first begins marketing each
such Licensed Product.  At the time that Vista satisfies each royalty obligation
hereunder, Vista shall have a fully paid-up, irrevocable license to the related
Licensed Product and patent (if any) without any further payments.

5.6   ADJUSTMENTS TO ROYALTY OBLIGATION IN THE EVENT OF NEWMAN'S EMPLOYMENT
TERMINATION.  If Vista terminates Newman's employment other than for cause, then
Newman and Vista will appoint a mutually acceptable third party to determine
whether or not an adjustment to the royalty obligations of this Agreement would
be equitable.  Such adjustments could address, for example, the equities of
whether or not to increase the rates set forth in Article 5.1, above, and
whether or not to establish an appropriate

* * * Confidential Treatment Requested


                                          5


<PAGE>

minimum sales level of the Licensed Products to be achieved by Vista for the
three (3) years immediately following Newman's termination.

In the event that Newman voluntarily terminates his employment with Vista, or if
he is terminated by Vista with cause, then this Article 5.6 shall be void and
shall not apply.

5.7   REDUCTION OF ROYALTY OBLIGATION.  In the event that Vista's use of its
rights granted under this Agreement infringes any third party's rights, then
Vista shall have the right to set off any compensation due to such third party
(or parties) against royalties due to Newman.

ARTICLE 6 -- REPORTS

6.1   Vista agrees to send  * * *    statements or reports to Licensor on or
before the  * * *   days of          * * *                    of each year
during the life of this Agreement stating in each such report the number and
description of each Licensed Product sold and the amount of royalties payable to
Newman thereon.  The first of such reports shall include all Licensed Products
sold between the effective date of this Agreement and the expiration of the
first full calendar quarter following the execution of this Agreement.  Each
subsequent report shall include all Licensed Products sold during the preceding
  * * *       .  Simultaneously with the making of each such report, Vista
agrees to pay any royalty then due and payable.

6.2   Vista agrees to maintain complete and accurate records in sufficient
detail to enable the royalties to be paid hereunder by Vista to be determined,
and further agrees to permit its books and records to be examined from
time-to-time to the extent necessary to verify the amount of royalty due and
payable to Newman under this Agreement.  Vista shall retain and make available
for audit such records for a period of   * * *  * * * after each Licensed
Product is sold, provided that Vista shall not be required to retain such
records beyond a period of  * * *       after date of termination or expiration
of this Agreement or the conversion to a fully paid license.

* * * Confidential Treatment Requested

ARTICLE 7 -- WARRANTY

7.1   Newman warrants, to the best of his knowledge, that he is the sole owner
of the Licensed Products and Technology free of any liens, encumbrances,
restrictions, and other legal or equitable claims, except as specifically stated
in Schedule 7.1 of this Agreement.

7.2   Newman shall use his best efforts to provide Vista with accurate
technical and engineering information, drawings, and data, but Newman makes no
other warranties concerning Licensed Products manufactured under this Agreement,
except as expressly stated in this Agreement.

ARTICLE 8 -- TERM AND TERMINATION

8.1   In case Vista fails to perform any of its obligations hereunder, Newman
may notify Vista in writing of such default and Newman shall have the option of
treating this Agreement as in full force and effect and taking proper steps to
recover royalties payable hereunder or of cancelling this License and Agreement,
provided, however, that in case Newman elects to cancel this License and
Agreement, he shall first send to Vista notice of his intention together with a
statement as to the basis of the intended action.  If within   * * *
after the receipt of such notice, Vista shall have met the objections presented
by Newman and shall have complied with the provisions of this Agreement, then
the notice shall become null and void and of no effect; otherwise the notice
shall remain effective and this License and Agreement shall cease and terminate
at the expiration of the     * * *        last mentioned above.

8.2   In the event that Newman materially breaches this Agreement, including
without limitation, the Warranty made in Article 7.1, then Vista may notify
Newman of his default.  If Newman fails to cure the default within     * * *
  of receipt of Vista's notice, then Vista, in addition to other remedies to
which it may be entitled, may offset any monetary damages suffered as a result
of any such default against royalties owed to

                                     AMENDMENT TO
                                  LICENSE AGREEMENT


      This Amendment to License Agreement (the "Amendment") is entered into as
of the 13th day of December, 1996, by Allen Newman, an individual ("Newman" or
"Licensor") and Vista Medical Technologies, Inc., 5451 Avenida Encinas, Suite A,
Carlsbad CA 92008 ("Vista" or "Licensee"), referred to individually as a "Party"
and together as the "Parties."

                                       RECITALS

      Newman and Vista have entered into a License Agreement dated September 2,
1994 (the "License Agreement"), pursuant to which an exclusive license to use
Licensor's Technology worldwide was granted to Vista.  Newman and Vista desire
to amend the License Agreement in connection with the proposed license by Vista
of certain technology to UROHEALTH Systems, Inc. ("UROHEALTH") and certain other
arrangements in connection therewith, so as to provide that to the extent the
terms of the License Agreement are inconsistent with the terms of that certain
License Agreement between Vista and UROHEALTH (the "UROHEALTH Agreement"), the
terms of the UROHEALTH Agreement shall govern.  In connection with the execution
of the UROHEALTH Agreement, Vista and UROHEALTH are entering into a Consulting
Agreement pursuant to which Vista will use its commercially reasonable efforts
to provide the services of Newman to UROHEALTH as set forth in such agreement.

      Capitalized terms used herein and not otherwise defined shall have the
meanings given them in the License Agreement.

      NOW, THEREFORE, the Parties agree as follows:

      1.     APPROVAL OF SUBLICENSE.  Pursuant to Article 2 of the License
Agreement, Newman hereby approves of the proposed sublicense of Licensor's
Technology and Licensed Products to UROHEALTH pursuant to the UROHEALTH
Agreement, a copy of which is attached hereto as EXHIBIT A.  Newman hereby
acknowledges and agrees that, from and after the date hereof, UROHEALTH shall
pursue the development and commercialization of certain of the Licensed Products
and Vista shall no longer have any responsibility for the development and
commercialization of such Licensed Products.  From and after the date hereof, to
the extent the terms of the License Agreement are inconsistent with the terms of
the terms and conditions of the UROHEALTH Agreement, the terms of the UROHEALTH
Agreement shall govern.  For instance, Sections 3 and 5.5 and Exhibit 1.2 (e.g.,
the time limit for products set forth on such exhibit) of the License Agreement
contain terms contradictory to the terms and conditions of the UROHEALTH
Agreement; the terms and conditions of the UROHEALTH Agreement shall govern.

      2.     PAYMENT.  In consideration of the execution of this Amendment,
Vista shall pay to Newman, within     * * *         of the execution of this
Amendment, the sum of                  * * *                 .

      3.     AMENDMENT OF CERTAIN SECTIONS OF THE LICENSE AGREEMENT.  Solely
with respect to Licensed Products under the UROHEALTH Agreement:

             (a)    Sections 5.1 and 5.3 of the License Agreement are hereby
deleted and replaced in their entirety as follows:

             "5.1   Vista shall pay to Newman     * * *           of the
             royalties received by Vista pursuant to Section 4.3 of the
             UROHEALTH Agreement.  Newman hereby acknowledges and agrees that
             royalties are only payable by UROHEALTH to Vista on the
                    * * *         manufactured by UROHEALTH and that no
             royalties are payable by UROHEALTH to Vista on        * * *
                                                              * * *

             5.3    The foregoing payments shall be payable    * * *  on or
             before the  * * *   day of             * * *                of
             each year in which payments are received from UROHEALTH under the
             UROHEALTH Agreement."

             (b)    The following sentence is hereby added Section 8.1 of the
License Agreement:

             "Any notice delivered to Vista hereunder shall simultaneously be
             sent to UROHEALTH at the address set forth in the UROHEALTH
             Agreement.  Newman shall not be entitled to terminate the license
             under this Agreement unless and until UROHEALTH has been given the
             same opportunity as Vista is entitled to hereunder to correct the
             failure to perform."

      4.     This Amendment will be governed by and construed under the laws of
the State of California as applied to agreements among California residents
entered into and to be performed entirely within California.

      5.     This Amendment may be executed in two or more counterparts, each
of which will be deemed an original, but all of which together will constitute
one and the same instrument.

                                   GRANT OF RIGHTS

      2.1    LICENSE.  In consideration of the license fees and royalties

             (a)    Vista shall, throughout the term of this Agreement, keep
Urohealth apprised of any Improvements that it has developed or is in the
process of developing.  Subject to Section 6.1, Urohealth shall have the right,
but not the obligation, to file and to prosecute patent applications with
respect to any such Improvements that might reasonably constitute patentable
inventions.  If Urohealth decides in its sole discretion not to file or
prosecute such patent applications with respect to any such Improvement, then
Vista shall have the right to do so for such Improvement at its expense.

             (b)    All Improvements shall be deemed to be part of the license
granted to Urohealth pursuant to Section 2.1 above and Vista shall own such
Improvements free and clear of any Urohealth claims.  Upon Urohealth's request
for all materials reasonably necessary for Urohealth to exercise its license
with respect to such Improvements, Vista shall promptly deliver such to
Urohealth.

      2.5    RIGHT OF FIRST REFUSAL TO MANUFACTURE AND SUPPLY.

             (a)    From the Effective Date through the date which is the
second anniversary of the cessation of Vista manufacturing a component of a
Licensed Product, Vista shall have the first right of refusal to manufacture and
supply to Urohealth Urohealth's requirements of the                 * * *
   * * *  (collectively, the "Video Equipment") for medical office use in
conjunction with a Licensed Product (the "Right of First Refusal").  Prior to
the first commercial sale of a Licensed Product, Urohealth shall notify Vista of
its requirements and specifications of the Video Equipment for such Licensed
Product (the "Requirements Notice").

             (b)    If such Requirements Notice is delivered prior to the  ***
    * * *   of the Effective Date, Vista and Urohealth shall negotiate in good
faith and shall agree on the terms and conditions to be applicable to the
manufacture and supply of the Video Equipment by Vista to Urohealth; provided
that Vista shall be obligated to meet the mutually-agreed upon specifications
for the Video Equipment and shall provide Urohealth with competitive pricing for
such Video Equipment.

             (c)    If such Requirements Notice is delivered following the
third anniversary of the Effective Date through the termination of the Right of
First Refusal as set forth above, Vista and Urohealth shall negotiate in good
faith for a period of    * * *         the terms and conditions of the
manufacture and supply of the Video Equipment by Vista.  The specifications and
pricing shall be mutually agreed upon by Vista and Urohealth.  In the event that
a definitive manufacturing and supply agreement is not entered into within such
 * * *        period, Urohealth may immediately thereafter enter into
discussions with a third party regarding such Video Equipment.  Urohealth shall
be permitted to enter into a definitive agreement with respect to such

* * * Confidential Treatment Requested


                                         -3-


<PAGE>

Video Equipment on terms and conditions no less favorable in the aggregate than
those last proposed by Urohealth or offered by Vista under this Section 2.4(c).
In the event that the terms and conditions offered by the third party are less
favorable in the aggregate than those last proposed by Urohealth or offered by
Vista, prior to entering into any agreement with such third party with respect
to the manufacture and supply of the specified Video Equipment, Urohealth shall
notify Vista in writing of the material terms and conditions of any such
proposed agreements.  Such notice shall be deemed an offer to Vista to enter
into definitive agreements on the same proposed terms and conditions.  Vista
shall have    * * *         to accept the offer contained in such notice.
Upon acceptance by Vista, the parties will negotiate in good faith to draft and
execute definitive agreements within     * * *        of acceptance.  If no
definitive agreements have been executed in such      * * *      period, the
Right of First Refusal shall lapse with respect to the specified Video Equipment
and Urohealth shall be free to license such Video Equipment to any third party
on any terms and conditions.

             (d)    The obligations of Urohealth under subparagraphs (a) and
(b) above shall be subject to Vista's ability to then manufacture and provide to
Urohealth Video Equipment of a quality and design for its intended purpose equal
to or better, in the aggregate, to the quality and design of competitive video
equipment then available to Urohealth, taking into account the relative costs of
the Video Equipment and the competitive video equipment.

      3.1    PATENTS AND TECHNOLOGY.  Vista owns all right, title, and interest
in the Patent Rights and Related Technical Information.  Urohealth shall have no
rights in the Patent Rights and Related Technical Information except as
expressly provided in this Agreement.

      3.2    IMPROVEMENTS.  Vista shall own all right, title, and interest in
any Improvements created during the term of this Agreement regardless of which
party is responsible for such Improvements, including all patent, copyright,
trade secret, and other intellectual property rights therein.  Upon Vista's
reasonable request, Urohealth shall execute all documents necessary to vest
title in Vista to any such Improvements.

      3.3    DEVELOPMENT OF LICENSED PRODUCTS.  Urohealth shall assume and pay
all Licensed Product development costs incurred by Urohealth from and after the
Effective Date and throughout the term of this Agreement.

      4.1    LICENSE FEE.  In consideration of the rights granted by Vista to
Urohealth pursuant to this Agreement, Urohealth shall pay Vista a license fee in
accordance with EXHIBIT D and royalties as set forth below.

      4.2    ROYALTIES.  For the purpose of calculating royalties due
hereunder, the following terms shall have the following meanings:

             (a)    "Gross Margin" shall mean 100 times (Net Revenue minus
Manufacturing Costs) divided by Net Revenue, calculated cumulatively for each
calendar year.

             (b)    "Net Revenue" means Urohealth's actual amounts invoiced
(exclusive of any separately itemized taxes, interest, service or maintenance
charges, finance charges, insurance and transportation costs actually paid by
Urohealth's customers) from all sales of the Licensed Products, less (i) any
customary and reasonable credits, refunds for returns or reasonable reserves for
bad debts, (ii) any customary and reasonable credits, rebates, discounts and
promotional allowances to customers and (iii) the amount of any sales, use or
other taxes required to be paid or withheld by Urohealth with respect to
payments due Vista.  In the event that any particular Licensed Product is sold
by Urohealth as part of a bundle or kit, the invoiced price for that particular
product shall be determined by multiplying the net selling price of the bundle
or kit by the fraction A/A+B where A is the suggested list price for the
Licensed Product sold separately (as documented by Urohealth's records) and B is
the suggested list price for the remaining products in the bundle or kit sold
separately (as documented by Urohealth's records).

             (c)    "Manufacturing Costs" shall mean (i) Urohealth's
manufacturing costs for the Licensed Products, including manufacturing overhead
as determined under generally accepted accounting procedures applied
consistently by Urohealth and attributable to the production of the Licensed
Products by Urohealth, in the case that Urohealth manufactures Licensed
Products; and (ii) the purchase price to Urohealth in the case that Urohealth
purchases the Licensed Products from a third party provided that such purchase
price is subject to the prior written approval of Vista, which shall not be
unreasonably withheld.

             (d)    "U.S./Direct Royalty Rate" shall mean       * * *
   * * *  and shall apply to all sales of Licensed Products to end-users located
in the United States and all direct sales of Licensed Products by Urohealth
(sales not through an independent distributor) in the rest of the world.

             (e)    "Foreign Indirect Royalty Rate" shall mean    * * *
   * * *         and shall apply to all indirect sales of Licensed Products
(sales through independent distributors) to end-users located outside the United
States.

      4.3    ROYALTY PAYMENT.  Urohealth will pay to Vista an amount equal the
sum of the U.S./Direct Royalty Rate and Foreign Indirect Royalty Rate on a
product-by-product

* * * Confidential Treatment Requested


                                         -5-


<PAGE>

and country-by-country basis through the later of (i) the expiration of the
last-to-expire patent within the Patent Rights with claims covering such
Licensed Product or (ii) the ninth anniversary of the Effective Date (the
"Royalty Termination Date").  In no event shall either the U.S./Direct Royalty
Rate or the Foreign Indirect Royalty Rate exceed       * * *          or fall
below      * * *       for any payment period.  All the foregoing amounts will
be calculated on a   * * *   basis and shall be paid in accordance with Section
4.4 below.  Following the Royalty Termination Date, Urohealth shall a fully-paid
up license to such Patent Rights and the Related Technical Information and
Improvements for such Patent Rights, subject to termination pursuant to Article
5 below.

      4.4    * * *  PAYMENTS.  All royalty payments owed by Urohealth to Vista
under this Agreement will be payable on a calendar * * *   basis no later than
* * *    * * *    after the end of each     * * *       .  Royalty reports shall
be provided by Urohealth to Vista with each royalty payment.  The royalty
reports shall show (i) the number of Licensed Products invoiced during the
calendar  * * *  in question, (ii) the total gross sales invoiced amount, (iii)
the applicable Manufacturing Costs, (iv) an itemization of deductions, (v) the
amount of royalties due and (vi) the method of calculation of royalties for such
calendar  * * *  .

      4.5    BOOKS AND RECORDS; AUDIT RIGHTS.  Urohealth agrees to make and
maintain such books, records and accounts as are reasonably necessary to verify
the payments due Vista under this Agreement.  At Vista's sole expense, an
independent certified public accountant, selected by Vista and reasonably
acceptable to Urohealth, who agrees to sign a nondisclosure agreement may, upon
reasonable notice and during normal business hours, but no more often than once
each year, inspect only those records of Urohealth on which the payments to
Vista under this Agreement are based.  The accountant may report only the
accuracy of the payments, but may not disclose confidential information,
including specific customers, quantities and pricing by channel or distributor.
If any audit hereunder reveals that Urohealth has failed properly to account for
and pay royalties owing to Vista hereunder, and the amount of any royalties
which Urohealth has failed properly to account for and pay during any    * * *
period exceeds by   * * *          or more the royalties actually accounted for
and paid to Vista for such period, Urohealth shall reimburse Vista for the cost
of the accountant.  Urohealth shall also, within    * * *         after
notification by Vista, pay to Vista any amounts shown as due under such audit,
regardless of whether Urohealth is required to reimburse Vista for the cost of
the accountant.


                                      ARTICLE 5
                                 TERM AND TERMINATION

      5.1    TERM.  The term of this Agreement shall commence on the Effective
Date and, unless earlier terminated pursuant to this Article 5, shall continue
in full force and effect indefinitely.  Notwithstanding the foregoing, the
royalty obligation set forth in


* * * Confidential Treatment Requested


                                         -6-


<PAGE>

Section 4.3 shall terminate as set forth therein and thereafter Urohealth shall
have a fully-paid up license as set forth herein.

      5.2    TERMINATION FOR BREACH.  In the event of a material breach of this
Agreement, the nonbreaching party shall be entitled to terminate this Agreement
by written notice to the breaching party if such breach is not cured within
  * * *    days after written notice is given by the nonbreaching party to the
breaching party specifying the breach.  The parties agree that if: (i)     * * *
royalty payments are not paid when due under Section 4.4, and Urohealth fails to
pay such royalties within the   * * *    days after written notification from
Vista, (ii) Urohealth fails to pay all prosecution, maintenance and infringement
costs associated with the Patent Rights within   * * *    days after written
notification from Vista, (iii) Urohealth fails to comply with the additional
qualifications set forth in Article 9 of this Agreement within   * * *
days after written notification from Vista or (iv) fails to meet mutually-agreed
upon performance standards set forth on attached EXHIBIT C, including the
establishment of a direct sales force and a marketing plan and budget for the
United States and the rest of the world, each shall be deemed to be a material
breach by Urohealth permitting Vista to terminate this Agreement immediately.

             (a)    Termination of this Agreement for any reason shall not

                               PATENTS AND INFRINGEMENT

      6.1    PATENT PROSECUTION.  Urohealth shall have the right but not the
obligation to prosecute all patents under the Patent Rights within the Field of
Use at Urohealth's expense.  If Urohealth does not prosecute a patent in a
particular country, Vista may do so, provided that Vista bears all costs and
expenses in connection with such prosecution.  Vista and Urohealth agree,
throughout the term of this Agreement, to cooperate in: (i) formulation of a
general intellectual property strategy; (ii) foreign filings; and (iii)
determination of the content of each new application, divisional continuation or
continuation-in-part.  Each further agrees to assist the other in any
formalities relating to the foregoing and each shall use its best efforts to
ensure that the other receives copies of all relevant correspondence.

      6.2    INFRINGEMENT CLAIMS.  If the production, sale or use of Licensed
Products by Urohealth results in any claim for patent infringement against
Urohealth, Urohealth shall promptly notify Vista thereof in writing.  As between
the parties to this Agreement, Urohealth shall have the right at its own expense
to defend and control the defense of any such claim against Urohealth, by
counsel of its own choice.  Vista shall provide such support to Urohealth as
Urohealth may reasonably request, in connection with such defense.

      6.3    ENFORCEMENT OF PATENT RIGHTS.  In the event that any of the Patent
Rights are infringed by a third party within the Field of Use, Urohealth shall
have the exclusive right, but not the obligation, to institute, prosecute and
control any action or proceeding with respect to such infringement, by counsel
of its choice, including any declaratory judgment action arising from such
infringement.  Urohealth shall be entitled to any and all proceeds recovered
from third parties as a result of the enforcement of the Patent Rights.  If
Urohealth does not take any action with respect to an infringement, then Vista
shall have the right to take action upon notice to Urohealth.  In such case,
Vista shall be entitled to any and all proceeds as a result of the enforcement
of the Patent Rights.  In the event both parties mutually agree to take action
against an infringer, then the proceeds as a result of the enforcement of the
Patent Rights shall be divided   * * *
      * * *   to each party's expenditures in connection with such enforcement.

Vista/McKinley Agreement                  4


<PAGE>

                                                                   EXHIBIT 10.25

                                  LICENSE AGREEMENT

         This agreement (the "Agreement") is entered into effective July 19,
1995 (the "Effective Date"), by and between Kaiser Aerospace and Electronics
Corporation ("Kaiser"), a California corporation, having its principal place of
business at 950 Tower Lane, Foster City, CA 94404 and Vista Medical
Technologies, Inc. ("Vista"), a California corporation, having its principal
place of business at 2752 Loker Avenue West, Carlsbad, CA 92008.

         1.        LICENSE; COOPERATION; COMMERCIALIZATION

         1.1  In consideration of Vista's obligations hereunder, Kaiser hereby
grants to Vista an exclusive, irrevocable, fully paid-up, perpetual, worldwide,
unlimited license (the "License") in the Field under the patent ("Patent") set
forth in Exhibit A, attached hereto and incorporated herein by this reference,
to use, sell, have sold and otherwise fully exploit the optical collimating
apparatus (the "Device") covered by the Patent and to manufacture (or have
manufactured) the Device pursuant to the terms of Section 1.4 below, as well as
a non-exclusive, irrevocable, fully paid-up, perpetual, worldwide license in the
Field to any underlying or related inventions, ideas, manufacturing processes,
methods of use, techniques, know-how, data, information, improvements,
modifications or derivatives, whether or not patentable or now existing that are
necessary or useful in exploiting the Device (the "Technology"), including,
without limitation, any and all patents and patent rights, copyrights, trade
secret rights, trademarks and other rights (the "Proprietary Rights") (the
Device and the Technology, including all Proprietary Rights contained therein,
shall be referred to collectively as the "Licensed Rights").  To enable Vista to
exercise the licenses granted herein and throughout the term of this Agreement,
Kaiser will promptly disclose and provide the Technology to Vista.  For the
purposes of this Agreement, the "Field" shall be defined as all applications in
or relating to medicine.

         1.2  Kaiser agrees to assist Vista in every proper way (i) to evidence
and perfect the License and (ii) to apply for, obtain and maintain any
regulatory approvals for the Device as incorporated into any and all medical
products developed pursuant to the licenses granted under this Agreement (the
"Products"), all of which Vista is granted the unilateral, exclusive,
transferable right (but not obligation) to do.  All such regulatory approvals
will be obtained by Vista in its name and, to the extent allowed by law, any
such existing rights or approvals (or applications therefor) are hereby assigned
to Vista and shall otherwise be for the sole benefit of Vista.  Kaiser will
execute all documents Vista may reasonably request for any of the foregoing
purposes.

         1.3  The License granted in Section 1.1 above shall become
non-exclusive if and only if Vista has (i) failed to develop, with the intent to
market, a 

<PAGE>

functional benchmark prototype of a Product incorporating the Device within
* * *     * * * following the Effective Date and (ii) has not, before the
expiration of such  * * *      * * * period, entered into a development program
for a Product incorporating the Device with Kaiser or a Kaiser-affiliated
company.  

         1.4  The parties will, in good faith, enter into a separate Device
manufacturing agreement (the "Manufacturing Agreement"), whereby Kaiser shall
exclusively manufacture the Device for Vista to fill all of Vista's Device
requirements.  Nevertheless, in the event that Kaiser or a Kaiser licensee fails
to supply Vista's Device requirements or otherwise materially breaches the terms
of the Manufacturing Agreement, Vista shall have the right to manufacture, or
have manufactured, the Device and Kaiser shall provide all reasonable and
necessary assistance therefor.

         2.   TERM AND TERMINATION

         2.1  This Agreement shall continue in effect unless and until
terminated as provided in this Section 2.

         2.2  If Vista determines that it is economically or technically
impractical or disadvantageous for it to continue development or marketing
regarding the Device, Vista may terminate this Agreement at any time upon ninety
(90) days written notice.

         2.3  If Vista materially breaches this Agreement and fails to commence
action to cure such breach within    * * *         of receipt of written notice
thereof from Kaiser, Kaiser may terminate this Agreement by written notice;
provided that if Vista in good faith disputes an allegation of breach, the cure
period will commence upon resolution of such dispute.

         2.4  If termination of this Agreement occurs, all rights licensed to
Vista hereunder shall revert to Kaiser and neither party shall have any
obligations to the other party under this Agreement, except for Sections 3, 5
and 6, which still survive termination; provided, however, that in no event will
Vista or any sublicensee, transferee or assignee be precluded from disposing of
its inventory or meeting its then existing supply obligations.

         3.   CONFIDENTIALITY; OWNERSHIP

         3.1  Each party agrees that all inventions, processes, materials,
know-how and ideas and all other business, technical and financial information
it obtains from the other are the confidential property of the disclosing party
("Confidential Information" of the disclosing party).  Except as expressly
allowed in this Agreement, the receiving party will hold in confidence and not
use or disclose any Confidential Information of the disclosing party and shall
similarly bind its employees in writing.  The receiving party shall not be
obligated under this Section 3 with respect to information that:

           (1)     is or has become readily publicly available through no fault
of the receiving party or its employees or agents; or

           (2)     is received from a third party lawfully in possession of
such information and lawfully empowered to disclose such information and
provided the receiving party abides by all restrictions imposed by such third
party; or

           (3)     was rightfully in the possession of the receiving party
prior to its disclosure by the other party provided the receiving party abides
by all restrictions imposed on its possession of such information; or

the receiving party without access to such Confidential Information; or

           (5)     is required by order of a government agency or court of
competent jurisdiction to be disclosed.     

         3.2  As between the parties, and subject to the rights granted to
Vista under this Agreement, ownership of the Licensed Rights is and shall remain
in Kaiser.

         3.3  All right, title and interest in and to any improvements or
modifications made to the Licensed Rights by Vista during the term of this

[57]                                   ABSTRACT

An optical collimating apparatus employs a semi-reflective concave mirror and
cholesteric liquid crystal element.  In one embodiment, the optical collimating
apparatus is used as a heads-up display device.  Images in the line of sight of
an observer substantially pass through a transmitter/combiner, semi-reflective
concave mirror, and cholesteric liquid crystal element to an observer.  Images
generated by an image source are focussed on the transmitter/combiner such that
the transmitter/ combiner reflects the images into the line of sight of the
observer.  The generated images are transmitted by the primarily transmissive
(convex) side of the semi-reflective concave mirror to the cholesteric liquid
crystal element.  The cholesteric liquid crystal element reflects the generated
images back toward the primarily reflective (concave) side of the
semi-reflective concave mirror, which in turn reflects the images back toward
the cholesteric liquid crystal element, which transmits the generated images to
the Observer.  In an alternative embodiment, such as in a flight simulator or
similar device, an image source projects images upon the primarily transmissive
(convex) side of a semi-reflective concave mirror which transmits the images to
a cholesteric liquid crystal element.  The images are reflected by the
cholesteric liquid crystal element back toward the primarily reflective
(concave) side of the semi-reflective concave mirror.  The images are then
reflected by the semi-reflective concave mirror back toward the cholesteric
liquid crystal element which transmits the images to the observer.

                             BACKGROUND OF THE INVENTION

    1.  Field of the Invention
    The present invention relates generally to the field of visual display
systems for use in aircraft, flight simulators, etc., and more particularly to
an apparatus for collimating a projected image at or near infinity, having high
transmission of images incident thereupon.
    2.  Description of the Prior Art
    Optical collimation apparatus capable of forming an image at or near
infinity of an object or a plurality of optically superimposed objects have been
known for some time. One such apparatus is described in U.S. Pat. No. Re 27,356,
reissued May 9, 1972. As disclosed, an apparatus having a single spherically
curved combining mirror is used as an image forming element. A primary image is
directed at the convex side of the mirror, which transmits the image to a
birefringent beam splitter array, positioned on the concave side of the mirror.
The Array reflects the image back to the spherical mirror, collimating the image
for viewing by an observer. Several polarizing filters in the light path
selectively direct that part of the primary image which returns to the spherical
mirror.
    The apparatus taught in Re No. 27,356 may be assembled in compact size and
light weight. However, due to the required multiple filtering and reflections of
the primary image, transmissivity of the primary image is low. For example, each
filtering and reflection of the primary image successively reduces the image's
intensity by approximately one-half. The result is an ultimate transmission in
the neighborhood of 0.5 to 10 percent of the original intensity of the primary
image.
    Another system, described in U.S. Pat. No. 3,940,203, issued Feb. 24, 1976,
is a variation on the previously discussed Pat. No. Re 27, 356 which replaces
the spherical mirror with a reflection-type holographic analog of a spherical
mirror. Because the disclosed apparatus must employ a relatively large number of
reflections and transmissions to properly control light which reaches the
observer, this technique also suffer from low transmission of the primary image.
By utilizing the improved reflection and transmission characteristics of the
holographic element, efficiency on the order of 6 to 10 percent of an image's
original intensity is achieved at best.
    Thus, there is a present need in the art for an optical collimation
apparatus with improved transmisivity of images. Further, since application of
such optical collimation apparatus may include helmet-mounted display systems or
other applications where size and weight are critical, there is a present need
for such an optical collimation apparatus which is both compact and
light-weight.

                               SUMMARY OF THE INVENTION

    The present invention is directed to an optical collimation apparatus that
utilizes the properties of cholesteric liquid crystals to form, preferably at or
near infinity, an image of an object or of a plurality of objects optically
superimposed, in the line of sight of an observer.
    According to a preferred embodiment of the present invention, the
collimation apparatus is formed of a semi-reflective concave mirror and a
cholesteric liquid crystal element.  The semi-reflective concave mirror and
cholesteric liquid crystal element are utilized together with a
transmitter/combiner placed in the line of sight of an observer.  An image
source, such as a cathode ray tube (CRT), liquid crystal display (LCD), or other
display device is provided such that images projected thereby are reflected by
the transmitter/combiner into the line of sight of the observer.
    The reflected image is passed through a circular polarizing filter to the
semi-reflective concave mirror, circularly polarizing the image.  The
semi-reflective concave mirror transmits the image to the cholesteric liquid
crystal element which is polarized in a rotary sense opposite that of the image,
causing the image to be reflected without reversal of its rotary sense, back to
the concave side of the semi-reflective concave mirror.  The image is then
reflected (and its rotary sense reversed) by the semi-reflective concave mirror
back toward the cholesteric liquid crystal element, which now transmits the
image or images to the observer.
    An image from the outside environment is transmitted through the
transmitter/combiner, through the semi-reflective concave mirror, and partially
transmitted by the cholesteric liquid crystal element to the observer, and
partially reflected by the cholesteric liquid crystal element back toward the
concave side of the semi-reflective concave mirror.  That portion of the image
reflected by the cholesteric liquid crystal element is in turn reflected by the
semi-reflective concave mirror back toward the cholesteric liquid crystal
element, which transmits the image to the observer.
    Transmission efficiency for this embodiment is increased over the prior art
in that fewer reflections and transmissions of the image takes place and in

<PAGE>

that the cholesteric liquid crystal element transmits and/or reflects a higher
percentage of the incident light than the reflective devices of the prior art.
    The invention will now be further described with reference to the
accompanying drawings.

                             DETAILED DESCRIPTION OF THE
                                 PREFERRED EMBODIMENT

    With reference to FIG. 1, a preferred embodiment of an optical collimating
apparatus according to the present invention is shown.  In such an embodiment,
optical collimating apparatus 30 is used in a heads-up display or image
combining display mode.  Optical collimating apparatus 30 consists of image
generating source 34, example, relying on a property of cholesteric elements, as
demonstrated in FIG. 4, that the wavelength of maximum reflection is angular
sensitive (i.e., as the angle of incidence increases, the wavelength of maximum
reflection is shifted toward the shorter wavelenths) the wavelength of maximum
reflection of the cholesteric liquid crystal element for normally incident light
may be increased to compensate for the shift toward the shorter wavelengths of
reflection for non-normally incident light.
    Another property of cholesteric elements, demonstrated in FIGS. 5(a) and
5(b), is that the separation between the angle of incidence (i) and angle of
reflection (r) is a function of the orientation, or tilt, of the helical axis of
the cholesteric layer. As the helical axis is tilted away from normal to the
surface of the cholesteric liquid crystal element the separation becomes
smaller.
    Thus, positioning of the reflected image in the line-of-sight of the
observer may be controlled by the composition of the element (as opposed to
positioning of the image source).
    Thus the disclosures and descriptions herein are purely illustrative and
are not intended to be in any sense limiting.

MEMORANDUM OF UNDERSTANDING

1.   This Memorandum describes the principles and terms of a strategic
     partnership between Cogent Light Technologies (CLT) and Vista Medical
     Technologies (VMT) to develop and market CLT single fiber light technology
     for emerging applications in cardiovascular surgery.

2.   CLT and VMT recognize that minimally invasive cardiovascular surgery
     represents a significant business opportunity, but is in an emerging phase
     and will require specifically designed systems to ensure efficacy.  VMT
     has formed a CardioThoracic Endosurgery Division and is committed to
     making a substantial investment in product development and marketing to
     maximize market share.  VMT possesses enabling proprietary technology for
     this application which has been validated by leading cardiovascular
     surgeons, who have joined VMT's clinical advisory board.  CLT owns
     proprietary single fiber light delivery systems which have substantial
     potential application in this field, when integrated with instrument or
     endoscope systems and marketed as a cardio-system solution.

3.   CLT and VMT therefore wish to co-operate to develop products for minimally
     invasive cardiac surgery which incorporate single fiber light delivery and
     are based upon a uniquely defined and designed light source.  Such a light
     source will incorporate standard Cogent connectors and technology.  The
     chassis design and possibly the power configuration of output ports will
     be unique.  The product will be available exclusively via VMT; Cogent will
     not provide customized single fiber light delivery systems to any other
     companies for which the business focus is minimally invasive cardiac
     surgical applications and VMT agrees to keep such know-how confidential
     and use such know-how only for the purposes contemplated by this
     Memorandum unless modified in writing by both parties.  The VMT
     cardio-system will be differentiated from standard Cogent products and
     will carry the logo Cogent Connection to reference the incorporation of
     CLT proprietary technology.  In addition, Cogent will provide to VMT on an
     exclusive basis its engineering know-how regarding the incorporation of
     single fiber and related technologies into products for minimally invasive
     cardiac surgery pursuant to this agreement that connect to its single
     fiber optic light delivery cables.  Although Cogent agrees not to solicit
     actively OEM relationships with companies for which the focus of business
     is the endocardio-thoracic market, it is understood, however, that CLT may
     market standard Cogent systems under the CLT label, either as a Cogent
     Light branded product or as a Cogent Connection branded product under a
     private label, without restriction on their application, as long as the
     same product is being sold either directly through its direct distribution
     channels or as a standard OEM product.  In the event that such systems are
     sold to companies for which the business focus is the endocardiac surgical
     market, Cogent will not make available to these companies its engineering
     methods for incorporating into surgical products the advantages afforded
     by single fiber optic light delivery systems.

     In return for CLT's exclusive co-operation with VMT in the development of
     lighted surgical instrumentation for minimally invasive cardiac
     procedures, VMT agrees to incorporate only the VMT single fiber optic
     light source developed by CLT as a part of the overall VMT system,
     provided that this light source meets all of VMT's performance
     requirements.

4.   It is recognized that VMT may elect to enter into a joint-marketing
     agreement with or be acquired by another company ("Third Party") with
     business activity concentrated in the minimally invasive cardiac area.  In
     this event, it is envisaged that the substance of the CLT/VMT agreement
     will also transfer, respectively, either by the creation of a three party
     agreement among VMT, CLT, and the Third Party or by the creation of an
     agreement between CLT and the Third Party.  It is agreed that CLT will
     participate in discussions prior to the finalization of such an agreement,
     but will do so as part of the CLT/VMT group.  In the event CLT elects not
     to become a party to such an agreement, CLT technology will continue to be
     available to VMT on a non-exclusive basis.

5.   The strategic relationship envisages three phases of co-operation.

         (i)    Phase One - product definition phase.  This phase will include
                definition of clinical requirements and technical milestones.
                During this Phase a definitive agreement will also be worked
                out; it is understood that for the duration of Phase One, CLT
                and VMT will work with each other exclusively on this program,
                pending the definitive agreement. (Two months)

         (ii)   Phase Two - product development and pre-production phase.  This
                phase will execute the program defined in Phase One and include
                ongoing clinical evaluation of prototypes and determination of
                manufacturing capacity (Nine months.)  During Phase Two, VMT
                will make a reasonable effort to enter into a marketing
                agreement with a Third Party with demonstrated leadership or
                high market potential in the minimally invasive cardiac market.
                Upon the signing of a mutually agreed letter of intent with
                such a third party and the completion of Phase Two prototype-
                verification, the parties will enter Phase Three.  In the event
                that such letter of intent is not signed, VMT and CLT agree to
                re-examine issues associated with exclusivity and to negotiate
                Phase Three requirements if continued exclusivity is mutually
                agreed upon.  In the event that VMT and CLT are unable to come
                to agreement on the terms of continued exclusivity, CLT will
                continue to make available to VMT its single fiber technology
                on a non-exclusive basis and will continue to supply

                on an exclusive basis the light source and any other products
                developed for VMT specifically under Phase Two.

         (iii)  Phase Three - manufacturing and marketing phase.  Products will
                be launched at the STS meeting in San Diego in January 1997,
                with shipments to begin no later than March 1997.  There will
                be no minimum sales requirements for 1997, but (assuming
                shipments begin in March 1997), sales targets will be mutually
                agreed for 1998 and subsequent years.

6.   No transfer of intellectual property from one side to the other is
     envisaged as a result of this agreement.  Improvement to existing
     technology derived from this agreement will remain the property of the
     owner of the original technology.  New intellectual property, if created,
     will be jointly owned by CTL and VMT and cross-licensed to each other.

7.   CLT and VMT will designate responsible staff members to manage each phase
     of this agreement; it is the responsibility of the staff member to
     co-ordinate response internally and to communicate with his/her opposite
     number.  For VMT during Phase One J. Lyon will be responsible for
     contractual matters, A. Newman for product definition and K. Hori (or
     designate) for establishment of determination of clinical requirements,
     technical configuration and milestones.

8.   The principles of this memorandum will be submitted to VMT's Board of
     Directors on February 15, for approval to proceed with Phase One.  CLT
     will receive similar approval on or around March 1, 1996.  It is
     understood that a definitive agreement at the end of Phase One is subject
     to the approval of both Boards of Directors.

    4.1  LICENSE FEE.  In consideration of the rights granted by Vista to
Urohealth pursuant to this Agreement, Urohealth shall pay Vista a license fee in
accordance with EXHIBIT D and royalties as set forth below.

    4.2  ROYALTIES.  For the purpose of calculating royalties due hereunder,
the following terms shall have the following meanings:

         (a)  "Gross Margin" shall mean 100 times (Net Revenue minus
Manufacturing Costs) divided by Net Revenue, calculated cumulatively for each
calendar year.

         (b)  "Net Revenue" means Urohealth's actual amounts invoiced
(exclusive of any separately itemized taxes, interest, service or maintenance
charges, finance charges, insurance and transportation costs actually paid by
Urohealth's customers) from all sales of the Licensed Products, less (i) any
customary and reasonable credits, refunds for returns or reasonable reserves for
bad debts, (ii) any customary and reasonable credits, rebates, discounts and
promotional allowances to customers and (iii) the amount of any sales, use or
other taxes required to be paid or withheld by Urohealth with respect to
payments due Vista.  In the event that any particular Licensed Product is sold
by Urohealth as part of a bundle or kit, the invoiced price for that particular
product shall be determined by multiplying the net selling price of the bundle
or kit by the fraction A/A+B where A is the suggested list price for the
Licensed Product sold separately (as documented by Urohealth's records) and B is
the suggested list price for the remaining products in the bundle or kit sold
separately (as documented by Urohealth's records).

         (c)  "Manufacturing Costs" shall mean (i) Urohealth's manufacturing
costs for the Licensed Products, including manufacturing overhead as determined
under generally accepted accounting procedures applied consistently by Urohealth
and attributable to the production of the Licensed Products by Urohealth, in the
case that Urohealth manufactures Licensed Products; and (ii) the purchase price
to Urohealth in the case that Urohealth purchases the Licensed Products from a
third party provided that such purchase price is subject to the prior written
approval of Vista, which shall not be unreasonably withheld.

         (d)  "U.S./Direct Royalty Rate" shall mean       * * *
  * * *  and shall apply to all sales of Licensed Products to end-users located
in the United States and all direct sales of Licensed Products by Urohealth
(sales not through an independent distributor) in the rest of the world.

         (e)  "Foreign Indirect Royalty Rate" shall mean    * * *
   * * *         and shall apply to all indirect sales of Licensed Products
(sales through independent distributors) to end-users located outside the United
States.

    4.3  ROYALTY PAYMENT.  Urohealth will pay to Vista an amount equal the sum
of the U.S./Direct Royalty Rate and Foreign Indirect Royalty Rate on a
product-by-product

* * * Confidential Treatment Requested

                                         -5-

and country-by-country basis through the later of (i) the expiration of the
last-to-expire patent within the Patent Rights with claims covering such
Licensed Product or (ii) the ninth anniversary of the Effective Date (the
"Royalty Termination Date").  In no event shall either the U.S./Direct Royalty
Rate or the Foreign Indirect Royalty Rate exceed    * * *          or fall below
    * * *       for any payment period.  All the foregoing amounts will be
calculated on a   * * *   basis and shall be paid in accordance
with Section 4.4 below.  Following the Royalty Termination Date, Urohealth shall
a fully-paid up license to such Patent Rights and the Related Technical
Information and Improvements for such Patent Rights, subject to termination
pursuant to Article 5 below.

    4.4     * * *  PAYMENTS.  All royalty payments owed by Urohealth to Vista
under this Agreement will be payable on a calendar * * *   basis no later than
* * *     * * *    after the end of each     * * *       .  Royalty reports
shall be provided by Urohealth to Vista with each royalty payment.  The royalty
reports shall show (i) the number of Licensed Products invoiced during the
calendar  * * *  in question, (ii) the total gross sales invoiced amount, (iii)
the applicable Manufacturing Costs, (iv) an itemization of deductions, (v) the
amount of royalties due and (vi) the method of calculation of royalties for such
calendar  * * *  .

    4.5  BOOKS AND RECORDS; AUDIT RIGHTS.  Urohealth agrees to make and
maintain such books, records and accounts as are reasonably necessary to verify
the payments due Vista under this Agreement.  At Vista's sole expense, an
independent certified public accountant, selected by Vista and reasonably
acceptable to Urohealth, who agrees to sign a nondisclosure agreement may, upon
reasonable notice and during normal business hours, but no more often than once
each year, inspect only those records of Urohealth on which the payments to
Vista under this Agreement are based.  The accountant may report only the
accuracy of the payments, but may not disclose confidential information,
including specific customers, quantities and pricing by channel or distributor.
If any audit hereunder reveals that Urohealth has failed properly to account for
and pay royalties owing to Vista hereunder, and the amount of any royalties
which Urohealth has failed properly to account for and pay during any    * * *
period exceeds by    * * *          or more the royalties actually accounted for
and paid to Vista for such period, Urohealth shall reimburse Vista for the cost
of the accountant.  Urohealth shall also, within    * * *         after
notification by Vista, pay to Vista any amounts shown as due under such audit,
regardless of whether Urohealth is required to reimburse Vista for the cost of
the accountant.


                                      ARTICLE 5
                                 TERM AND TERMINATION

    5.1  TERM.  The term of this Agreement shall commence on the Effective Date

<PAGE>

Section 4.3 shall terminate as set forth therein and thereafter Urohealth shall
have a fully-paid up license as set forth herein.

    5.2  TERMINATION FOR BREACH.  In the event of a material breach of this
Agreement, the nonbreaching party shall be entitled to terminate this Agreement
by written notice to the breaching party if such breach is not cured within
* * *    days after written notice is given by the nonbreaching party to the
breaching party specifying the breach.  The parties agree that if: (i)     * * *
royalty payments are not paid when due under Section 4.4, and Urohealth fails to
pay such royalties within the    * * *    days after written notification from
Vista, (ii) Urohealth fails to pay all prosecution, maintenance and infringement
costs associated with the Patent Rights within    * * *    days after written
notification from Vista, (iii) Urohealth fails to comply with the additional
qualifications set forth in Article 9 of this Agreement within   * * *
days after written notification from Vista or (iv) fails to meet mutually-agreed
upon performance standards set forth on attached EXHIBIT C, including the
establishment of a direct sales force and a marketing plan and budget for the
United States and the rest of the world, each shall be deemed to be a material
breach by Urohealth permitting Vista to terminate this Agreement immediately.

    5.3  TERMINATION FOR INSOLVENCY.  This Agreement may be terminated by a
party, with notice, (i) upon the institution by or against the other party of
insolvency, receivership or bankruptcy proceedings which proceedings are not
dismissed within sixty (60) days, (ii) upon the other party's assignment for the
benefit of creditors, or (iii) upon the other party's dissolution or ceasing to
do business.

    5.4  EFFECT OF TERMINATION.

         (a)  If Vista terminates this Agreement pursuant to Sections 5.2 or
5.3 hereof, (a) the licenses granted to Urohealth under Article 2 of this
Agreement shall terminate, (b) all rights to the Patent Rights, Related
Technical Information and Improvements shall revert to Vista and (c) all rights
to develop, make, have made, use, sell and import all Licensed Products shall
revert to Vista.

         (b)  If Urohealth terminates this Agreement pursuant to Sections 5.2
or 5.3 hereof, the provisions of Sections 2.1, 2.2, 2.3, 2.4, 5.4 and 5.5 and
Articles 3 and 4 of this Agreement shall survive; PROVIDED, HOWEVER, if
Urohealth fails to perform or observe or otherwise breaches a material
obligations under this Agreement, which failure or breach is unremedied for a
period of   * * *     days after receipt by Urohealth of written notice thereof
from Vista, Vista shall have the right to terminate this Agreement with the same
effect as if Vista were to terminate this Agreement pursuant to Section 5.4(a)
hereof.

    5.5  SURVIVAL.

either party hereto from any liability which at the time of such termination has
already accrued to the other party.

Urohealth shall have the right to sell or otherwise dispose of its existing

                               PATENTS AND INFRINGEMENT

    6.1  PATENT PROSECUTION.  Urohealth shall have the right but not the
obligation to prosecute all patents under the Patent Rights within the Field of
Use at Urohealth's expense.  If Urohealth does not prosecute a patent in a
particular country, Vista may do so, provided that Vista bears all costs and
expenses in connection with such prosecution.  Vista and Urohealth agree,
throughout the term of this Agreement, to cooperate in: (i) formulation of a
general intellectual property strategy; (ii) foreign filings; and (iii)
determination of the content of each new application, divisional continuation or
continuation-in-part.  Each further agrees to assist the other in any
formalities relating to the foregoing and each shall use its best efforts to
ensure that the other receives copies of all relevant correspondence.

    6.2  INFRINGEMENT CLAIMS.  If the production, sale or use of Licensed
Products by Urohealth results in any claim for patent infringement against
Urohealth, Urohealth shall promptly notify Vista thereof in writing.  As between
the parties to this Agreement, Urohealth shall have the right at its own expense
to defend and control the defense of any such claim against Urohealth, by
counsel of its own choice.  Vista shall provide such support to Urohealth as
Urohealth may reasonably request, in connection with such defense.

    6.3  ENFORCEMENT OF PATENT RIGHTS.  In the event that any of the Patent
Rights are infringed by a third party within the Field of Use, Urohealth shall
have the exclusive right, but not the obligation, to institute, prosecute and
control any action or proceeding with respect to such infringement, by counsel
of its choice, including any declaratory judgment action arising from such
infringement.  Urohealth shall be entitled to any and all proceeds recovered
from third parties as a result of the enforcement of the Patent Rights.  If
Urohealth does not take any action with respect to an infringement, then Vista
shall have the right to take action upon notice to Urohealth.  In such case,
Vista shall be entitled to any and all proceeds as a result of the enforcement
of the Patent Rights.  In the event both parties mutually agree to take action
against an infringer, then the proceeds as a result of the enforcement of the
Patent Rights shall be divided   * * *        * * *   to each party's
expenditures in connection with such enforcement.

otherwise generally available to the public;

         (c)  Information which the Receiving Party can document was or is in
its possession at the time of disclosure and was not acquired directly or
indirectly from such party.

    7.2  EXCEPTIONS.  The Receiving Party may disclose Proprietary Information
of the other:

         (a)  In connection with the order of a court of law or in compliance
with laws or regulations relating to registrations or sale of securities, or as
is reasonably necessary in connection with the prosecution, maintenance or
enforcement of the Patent Rights or obtaining product approvals upon notice to
the other party; or

         (b)  If such information is also rightfully acquired from a third
party who, to the best of such party's knowledge and belief, is entitled to
rightfully make such disclosure, but only to the extent such party complies with
any restrictions imposed by the third party.


                                      ARTICLE 8
                                      WARRANTIES

proprietary rights of any third party;

         (e)  As of the Effective Date, there are no existing or threatened
actions, suits or claims pending against Vista with respect to the Patent Rights

Patent Rights existing as of the Effective Date, and Vista does not own rights
in any other patent or patent application, the claims of which relate to the
manufacture, sale or use of a product within the Field of Use or that would
dominate the claims of a patent or application within the Patent Rights.

    8.2  DISCLAIMER.  EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN THIS
AGREEMENT, VISTA MAKES NO REPRESENTATIONS AND EXTENDS NO WARRANTIES OF ANY KIND,
EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO, WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

third party claiming any rights to the rights granted herein royalties on a
Licensed Products pending resolution of any dispute with each third party or
subject to any injunction with the prior written consent of Vista, the royalty
payments of Urohealth due hereunder for such Licensed Product shall be reduced
by such payments, but such reduction shall be no more than     * * *
of the amount due during such payment period.

                                    MISCELLANEOUS

    10.1 PRODUCT LIABILITY INDEMNITY.  Urohealth agrees to indemnify and defend

paid to GDE for such period, Vista shall reimburse GDE for the cost of the

ARTICLE 9 - INTELLECTUAL PROPERTY INDEMNITY

GDE shall indemnify, hold harmless and defend Vista from and against any and all
suits, actions, damages, costs, losses, expenses (including reasonable
attorneys' fees) and other liabilities arising from or in connection with any
claim that the Licensed Products in the form delivered to Vista infringes or
violates any United States patent, copyright, trademark, trade secret or other
proprietary right of any third party.  Vista agrees to promptly notify GDE in
writing of such claim, suit or proceeding and give GDE authority to proceed as
contemplated herein, and, at GDE's expense, give GDE proper and full information
and assistance to settle and/or defend any such claim, suit or proceeding.
Without limiting GDE's obligations as set forth herein, GDE may, at its sole
option, either procure for Vista the right to continue using the Licensed
Products in the form delivered, or, if such is not possible, replace or modify
the Licensed Products so that it becomes non-infringing.  During the time when
GDE is contemplating or implementing its options, Vista shall have no obligation
to make royalty payments to GDE for such Licensed Items that are the subject of
the infringement claim.  GDE shall have no liability for any above mentioned
claim based upon the use of other than the unaltered version of the Licensed
Products if such infringement would have been avoided by the use of the
unaltered version of the Licensed Products.  In the event Vista becomes aware of
a potential infringer of GDE's intellectual property rights in the Licensed
Products, Vista shall promptly notify GDE, in writing, and GDE agrees to use
reasonable efforts to promptly protect GDE's intellectual property rights.

                                    EXHIBIT B


REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF GDE:

     GDE hereby represents, warrants and agrees that:

     (a)     The shares of Common Stock of Vista issued in connection with the
License Agreement (the "Shares") will be "restricted securities" as such term is
used in the rules and regulations under the Securities Act of 1933, as amended
(the "Securities Act") and that such securities have not been and will not be
registered under the Securities Act or any state securities law, and that such
securities must be held indefinitely unless registration is effected or transfer
can be made pursuant to appropriate exemptions under the Securities Act (such as
Rule 144);

     (b)     GDE is purchasing the Shares for investment for its own account and
not with a view to or for sale in connection with any distribution thereof and
it has no intention of selling such securities in a public distribution in
violation of the federal securities laws or any applicable state securities
laws; provided that nothing contained herein will prevent GDE from selling or
transferring such securities in compliance with the terms of applicable federal
and state securities laws;

     (c)     GDE is an "accredited investor" within the meaning of paragraph (a)
of Rule 501 of Regulation D promulgated by the Securities and Exchange
Commission (the "Commission") and an "excluded purchaser" within the meaning of
Section 25102(f) of the California Corporate Securities Law of 1968; and

     (d)     Vista will affix the following legend (in addition to any other
legend(s), if any, required by applicable state corporate and/or securities
laws) to certificates for the Shares:

             "These securities have not been registered under the
             Securities Act of 1933, or any state securities laws.
             They may not be sold, offered for sale, pledged or
             hypothecated in the absence of a registration
             statement in effect with respect to the securities
             under all applicable federal and state securities laws
             or an opinion of counsel satisfactory to the
             Corporation that such registration is not required or
             unless sold pursuant to Rule 144 of such Act."

     (e)     Prior to any proposed sale or transfer of any of the Shares, unless
(i) pursuant to and in compliance with Rule 144 or (ii) there is in effect a
registration statement under the Securities Act covering the proposed transfer,
GDE shall give written notice to Vista of GDE's intention to effect such sale or
transfer.  Each such notice shall describe the manner and circumstances of the
proposed sale or transfer in sufficient detail, and shall be


                                      -15-
<PAGE>

accompanied by either (i) a written opinion of legal counsel who shall be
reasonably satisfactory to Vista addressed to Vista and reasonably satisfactory
in form and substance to Vista's counsel, to the effect that the proposed sale
or transfer of the Common Stock may be effected without registration under the
Securities Act, or (ii) a "no action" letter from the Commission to the effect
that the sale or transfer of such securities without registration will not
result in a recommendation by the staff of the Commission that enforcement
action be taken with respect thereto, whereupon GDE shall be entitled to sell or
transfer such securities in accordance with the terms of the notice delivered by
GDE to Vista.  Each new certificate evidencing the Common Stock so sold or
transferred shall bear the appropriate restrictive legends set forth above,
except that such certificate shall not bear such restrictive legend if, in the
opinion of counsel for Vista, such legend is not required in order to establish
or assist in compliance with any provisions of the Securities Act or any
applicable state securities laws.

     (f)     GDE hereby agrees that, during the period of duration specified by
Vista and an underwriter of common stock or other securities of Vista, following
the effective date of a registration statement of Vista filed under the
Securities Act, it shall not, to the extent requested by Vista and such
underwriter, directly or indirectly sell, offer to sell, contract to sell
(including, without limitation, any short sale), grant any option to purchase or
otherwise transfer or dispose of (other than to donees who agree to be similarly
bound) any securities of Vista by it at any time during such period; PROVIDED,
HOWEVER, that:

             i)     such agreement shall not exceed 180 days for the first such
registration statement of Vista which covers Common Stock (or other securities)
to be sold on its behalf to the public in an underwritten offering;

             ii)    such agreement shall not exceed 90 days for any subsequent
registration statement of Vista which covers Common Stock (or other securities)
to be sold on its behalf to the public in an underwritten offering; and

           iii)     all execution officers and directors of Vista enter into
similar agreements.

     In order to enforce the foregoing covenant, GDE agrees and acknowledges
that Vista may impose stop-transfer instructions with respect to the Shares
until the end of such period.  Notwithstanding the foregoing, the obligations
described in this section shall not apply to a registration relating solely to
employee benefit plans on Form S-8 or similar forms which may be promulgated in
the future, or a registration relating solely to a SEC Rule 145 transaction on
form S-4 or similar forms which may be promulgated in the future.

       necessary for access to the Building and if at any time any portion of
       the Premises includes less than an entire floor, the common toilets,
       corridors and elevator lobby on such floor and any other common area
       provided by Landlord on such floor; but such rights shall always be

                                    BASE RENT

                                   ARTICLE IV

                                COMMENCEMENT DATE

4.1    COMMENCEMENT DATE:  The Commencement Date hereunder shall be the earliest
       of (i) the date upon which Tenant's personnel occupy all or any part of
       the Premises for the conduct of its business; or (ii) the Substantial
       Completion Date (as hereinafter defined).

4.2    PREPARATION OF THE PREMISES. (a) Landlord shall exercise all reasonable
       efforts to complete the work (Landlord's Work) necessary to prepare the
       Premises for Tenant's use and occupancy pursuant to the plans and
       specifications attached hereto as Exhibit TP (the "Buildout Plan") and in
       accordance with Landlord's building standard except as so noted on the
       Buildout Plan, but Tenant shall have no claim against Landlord for
       failure so to complete such work except the right to terminate this Lease
       in accordance with Section 4.2(c). Landlord shall pay for all costs
       associated with the completion of Landlord's Work pursuant to the
       Buildout Layout Plan, except for such costs as are specifically noted as
       Tenant Costs, if any.  Any costs associated with any changes made by
       Tenant (the "Tenant Change Costs") to any part of the Buildout Tenant's
       Layout Plan shall be paid entirely by Tenant, plus interest at the rate
       of twelve percent (12%), by adding to the amount of Base Rent an
       additional payment to be made to Landlord with each monthly payment of
       Base Rent due hereunder.  Each such additional payment shall be equal to
       an amount which, if


                                        5

<PAGE>

       paid in equal monthly installments over the remainder of the Term,
       applied first to interest and the remainder to principal would fully
       amortize a loan in the amount of the Tenant Change Costs plus interest at
       a rate of twelve percent (12%) per annum.

       (b)  The Premises shall be deemed ready for occupancy on the first
       day (the "Substantial Completion Date") as of which all of the
       following conditions have occurred: (1) Landlord's Work has been
       completed except for items of work (and, if applicable, adjustment
       of equipment and fixtures) which can be completed after occupancy
       has been taken without causing undue interference with Tenant's
       use of the Premises (i.e., so-called "punch list" items), and (2)
       Tenant has been given notice of the substantial completion of
       Landlord's Work, and (3) if required, Landlord has received a
       certificate of occupancy for the Premises.  Landlord shall
       complete as soon as conditions permit all "punch list" items and
       Tenant shall afford Landlord access to the Premises for such
       purposes.

4.3    CONCLUSIVENESS OF LANDLORD'S PERFORMANCE.  Except to the extent to which
       Tenant shall have given Landlord notice, not later than the end of the
       second full calendar month next beginning after the completion of the so-
       called "punch list" items, of respects in which Landlord has not
       performed Landlord's Work, and except in the case of latent defects as to
       which Tenant shall notify Landlord not later than the end of the twelfth
       (12th) full calendar month following the completion of the punch list
       items, Tenant shall have no claim that Landlord has failed to perform any
       of Landlord's Work.  Except for Landlord's Work, the Premises are being
       leased in their condition as is without representation or warranty by
       Landlord.  Tenant acknowledges that it has inspected the Premises and
       common areas of the Building and, except for Landlord's Work, have found
       the same satisfactory.

4.4    TENANT'S DELAYS. (a) If a delay shall occur in the Substantial Completion
       Date as the result of:

            (i)    any request by Tenant that Landlord delay in the
            commencement or completion of Landlord's Work for any reason;

            (ii)   any change by Tenant in any of Tenant's Layout Plan;

            (iii)  any special requirement of Tenant's Layout Plan not in
            conformity with Landlord's building standards;

            (iv)   any other act or omission of Tenant or its officers,
            agents, servants or contractors; or


                                        6

<PAGE>

            (v)    any reasonably necessary displacement of any of
            Landlord's Work from its place in Landlord's construction
            schedule resulting from any of the causes for delay referred
            to in clauses (i), (ii), (iii) and (iv) of this paragraph and
            the fitting of such work back into such schedule; then the
            term of this Lease shall be correspondingly extended by the
            number of days of delay; provided, however, that in the event
            the delay in the Substantial Completion Date is equal to or
            exceeds twenty (20) days ("Substantial Delay") , then the
            Landlord shall give Tenant prompt notice of any such
            Substantial Delay and Tenant shall, within ten (10) days
            after receipt of such notice and demand therefor, pay to
            Landlord for each day of such delay the amount of Basic Rent
            and other charges that would have been payable hereunder had
            the Commencement Date occurred immediately prior to such
            delay.

       (b)  If a delay in the Substantial Completion Date, or if any
       substantial portion of such delay, is the result of Force Majeure,
       and such delay would not have occurred but for a delay described
       in paragraph (a), such delay shall be deemed. added to the delay
       described in that paragraph.

       (c)  The delays referred to in paragraphs (a) and (b) are herein
       referred to collectively and individually as "Tenant's Delay".

       (d)  If, as a result of Tenant's Delay(s), the Substantial
       Completion Date is delayed in the aggregate for more than sixty
       (60) days, Landlord may (but shall not be required to) at any time
       prior to the Commencement Date terminate this Lease by giving
       written notice of such termination to Tenant and thereupon this
       Lease shall terminate without further liability or obligation on
       the part of either party, except that Tenant shall pay to Landlord
       the cost theretofore incurred by Landlord in performing Landlord's
       Work, plus an amount equal to Landlord's out-of-pocket expenses
       incurred in connection with this Lease, including, without
       limitation, brokerage and legal fees, together with any amount
       required to be paid pursuant to paragraph (a) through the
       effective termination date.

       the Premises are in conformity with federal, state and local
       statutes, regulations, ordinances, and policies including those

       General Laws Chapter 21E, and the regulations promulgated
       thereunder, and any applicable governmental agencies.  The right
       granted to Landlord herein to inspect the Premises shall not

       Hazardous Materials, it being understood that Tenant shall be
       solely responsible for all liability in connection therewith;

       alterations, additions or improvements in or to the Premises during the
       Term of this Lease without the prior written consent of Landlord, which
       consent shall not be unreasonably withheld or delayed provided that
       Tenant fully complies with the provisions of this Section 5.2. Any such
       alterations, additions or improvements shall (i) (except as hereinafter
       provided) be in accordance with complete construction plans and
       specifications approved by Landlord, (ii) be made only in accordance with
       construction rules and regulations of Landlord in effect from time to
       time and only by Landlord's contractors or by contractors or mechanics
       approved by Landlord, (iii) be made at Tenant's sole expense and, if the
       same would unreasonably disturb other tenants of the Building, at times
       other than during normal business hours and (v) except for Tenant's
       Removable Property, as defined below, become part of the Premises and the
       property of Landlord.

       (b)    All articles of personal property and all business
       fixtures, machinery and equipment and furniture owned or installed
       by Tenant solely at its expense in the Premises ("Tenant's
       Removable Property") shall remain the property of Tenant and may
       be removed by Tenant at any time prior to the expiration of this
       Lease, provided that Tenant, at its expense, shall repair any
       damage to the Building caused by such removal.

       (c)    Notice is hereby given that Landlord shall not be liable
       for any labor or materials furnished or to be furnished by
       contractors, mechanics or suppliers to Tenant upon credit, and
       that no mechanic's or other lien for any such labor or materials
       shall attach to or affect the reversion or other estate or
       interest of Landlord in and to the Premises.  To the maximum
       extent permitted by law, at such time as any contractor commences
       to perform work on behalf of Tenant, or any supplier commences to
       provide materials to Tenant, such contractor (and any
       subcontractors) or supplier shall furnish a written statement
       acknowledging the provisions set forth in the prior clause.
       Whenever and as often as any mechanic's lien shall have


                                       10

       been filed Against the Property based upon any act or interest of Tenant
       or of anyone claiming through Tenant, Tenant shall forthwith take such
       action by bonding, deposit or Payment as will remove or satisfy the lien.

       (d)    In the course of any work being performed by Tenant,
       including without limitation the "field installation" of any
       Tenant Removable Property, Tenant agrees to use labor compatible
       with that being employed by Landlord for work in or to the
       Building or other buildings owned by Landlord or its affiliates,
       and not to employ or permit the use of any labor or otherwise take
       any action which might result in a labor dispute involving
       personnel providing services in the Building pursuant to
       arrangements made by Landlord.


                                   ARTICLE VI

                            ASSIGNMENT AND SUBLETTING

6.1    PROHIBITION.(a) Except as hereinafter provided, Tenant covenants and
       agrees that neither this Lease nor the term and estate hereby granted,
       nor any interest herein or therein, will be assigned, mortgaged, pledged,
       encumbered or otherwise transferred and that neither the Premises nor any
       part thereof will be encumbered in any manner by reason of any act or
       omission on the part of Tenant, or used or occupied or permitted to be
       used or occupied, by anyone other than Tenant, or for any use or purpose
       other than a Permitted Use, or be sublet (which term, without limitation,
       shall include granting of concessions, licenses and the like) in whole or
       in part, or be offered or advertised for assignment or subletting, in
       each case without first obtaining the written approval of Landlord, which
       approval shall not be unreasonably withheld or delayed.

       (b)    Except as provided below, the provisions of paragraph (a)
       of this Section shall apply to (i) a single transfer or an
       orchestrated series of transfers of a majority of the stock or
       partnership interests or other evidences of ownership of or
       interest in Tenant as if such transfer were an assignment of this
       Lease and (ii) to any transfer of such stock or interests the
       effect of which would be to constitute an assignment of this
       Lease.  Notwithstanding the foregoing, the provisions of paragraph
       (a) of this Section shall not apply to any transactions by Tenant
       with an entity into or with which Tenant is merged or consolidated
       or with an entity to which substantially all of Tenant's assets
       are transferred or with any entity which controls or is controlled
       by Tenant or is under common control with Tenant or with which
       Tenant, directly or indirectly, has a fifty percent (50%) or
       greater ownership interest, or which directly or indirectly, has a
       fifty percent (50%) or greater interest in Tenant, provided that
       in any of


                                       11

<PAGE>

       such events (x) Landlord is provided with evidence satisfactory to it
       that the successor to Tenant has a net worth computed in accordance with
       generally accepted accounting principles at least equal to the net worth
       of Tenant immediately prior to such merger, consolidation or transfer,
       and (y) in the case of any assignment of this Lease, the assignee agrees
       directly with Landlord, by written instrument in form reasonably
       satisfactory to Landlord, to be bound by all the obligations of Tenant
       hereunder including, without limitation, the covenant against further
       assignment and subletting except in accordance with the express
       provisions of this Lease.

       (c)    If this Lease be assigned, or if the Premises or any part
       thereof be sublet or occupied by anyone other than Tenant,
       Landlord may, if Tenant is not paying timely the Base Rent,
       Tenant's share of operating and Tax Expenses, or any other charges
       due under this Lease, collect rent and other charges from the
       assignee, subtenant or occupant, and apply the net amount
       collected to the rent and other charges herein reserved, but no
       such assignment, subletting, occupancy, collection or modification
       of any provisions of this Lease shall be deemed a waiver of this
       covenant, or the acceptance of the assignee, subtenant or occupant
       as a tenant or a release of the original named Tenant from the
       further performance by the original named Tenant hereunder.  No
       assignment or subletting hereunder shall relieve Tenant from its
       obligations hereunder and Tenant shall remain fully and primarily
       liable therefor.  No such assignment, subletting, or occupancy
       shall affect Permitted Uses.

6.2    SUBLEASE RIGHTS.  Notwithstanding the prohibition set forth in Section
       6.1, Landlord shall not withhold its consent to a subletting or
       sublettings requested by Tenant, provided that: (i) in Landlord's
       reasonable judgment, the business of the proposed subtenant or the
       proposed use of the sublet premises will not adversely affect the
       reputation or image of the Building (subleases for governmental uses, for
       medical or dental offices or for health or fitness facilities being
       examples of businesses or uses which may adversely affect the Building's
       reputation or image as a first class office building); (ii) the total
       number of tenants (including Tenant) occupying any floor within the
       Premises at any one time shall not exceed four (4), which number shall be
       prorated for partial floors; (iii) such sublease(s) shall not, in the
       aggregate, cover more than 50% of the Rentable Area of the Premises; (iv)
       the rent to be derived by such sublease is payable monthly at a fixed
       rate or at a rate which is determinable from the terms of the sublease
       and not based on the net or gross income or profits derived by such
       subtenant from the Premises; and (v) Landlord has been furnished with
       information sufficient to make a determination as to each of the
       foregoing requirements.  If Landlord shall withhold such consent, it
       shall set forth in writing the reasons therefor.


                                       12

6.3    FIRST OFFER RIGHT.  In the event that Tenant shall desire to enter into a
       sublease otherwise permitted under the foregoing provisions of this
       Article 6, then Tenant shall give Landlord notice thereof and Landlord
       may elect to sublease such space from Tenant on the same terms and
       conditions stated in such notice by giving notice to Tenant of such
       election not later than fifteen (15) days after receiving notice of such
       offer from Tenant.  In the event that Landlord shall not elect so to
       sublease such space for any reason, then Tenant may enter into such
       sublease within one hundred eighty (180) days after Landlord has elected
       not to sublease such space on terms and conditions no more favorable to
       the subtenant than those offered to Landlord.  If Tenant shall not so
       enter into such sublease, or if, after Landlord has elected not to
       sublease such space, Tenant shall materially alter the terms and
       conditions thereof, Tenant shall again notify Landlord and Landlord shall
       have an additional fifteen (15) days within which to elect to enter into
       such sublease.  In the event that Landlord so subleases such space from
       Tenant, Landlord shall be entitled to sub-sublease such space (or any
       portion thereof) without restriction or consent by Tenant.

6.4    SHARING OF SUBLEASE PROFITS.  If the rent and other sums received by
       Tenant on account of a permitted sublease exceed the sum of (i) the Base
       Rent and Tenant's Share of operating and Tax Expenses allocable to the
       Premises subject to the sublease (in the proportion of the Rentable Area
       of such space to the entire Premises), (ii) reasonable legal fees and
       brokerage commissions incurred by Tenant in connection with such
       subleasing, and (iii) an amortization factor for the undepreciated value
       (computed consistently with generally accepted accounting principles, and
       amortized in equal monthly payments over the then remainder of the Term
       of this Lease) of any improvements installed in the portion of the
       Premises affected by such sublease at the sole cost and expense of
       Tenant, Tenant shall pay to Landlord, as additional rent, 100% of such
       excess, as received by Tenant.

       exterior walls and structure of the Building (including all fire and life
       safety, plumbing, mechanical and electrical or other Building systems
       installed by Landlord), all insofar as they affect the Premises or Common
       Areas, except that Landlord shall in no event be responsible for (i) the

<PAGE>

       Premises or (ii) any condition in the Premises or the Building caused by
       any act or omission of Tenant,, or its employees invitees, agents or
       contractors.

       (b)    Landlord shall not be liable for any failure to make
       repairs which, under the provisions of this Section 7.1 or
       elsewhere in this Lease, Landlord has undertaken to make with
       respect to any portion of the Building within the Premises or
       under the control of Tenant unless Tenant has given notice to
       Landlord of the need to make such repairs, and Landlord has failed
       to commence to take appropriate actions and/or make such repairs
       (as the case may be) within a reasonable time after receipt of
       such notice based upon the nature of the repairs or thereafter
       fails to proceed with reasonable diligence to complete such
       repairs.  Landlord shall notify Tenant promptly if Landlord
       disagrees that the repairs set forth in Tenant's notice need to be
       made.

7.2    TENANT'S AGREEMENT.(a) Tenant will keep neat and clean and maintain in
       good order, condition and repair the Premises and every part thereof,
       excepting only that maintenance and those repairs for which Landlord is
       responsible under the terms of this Lease and excepting also reasonable
       wear and tear of the Premises, and damage by fire or other casualty and
       as a consequence of the exercise of the power of eminent domain; and
       shall surrender the Premises, at the end of the Term, in such condition.
       Without limitation, Tenant shall continually during the Term of this
       Lease maintain the Premises in accordance with all laws, codes and
       ordinances from time to time in effect and all directions, rules and
       regulations of the proper officers of governmental agencies having
       jurisdiction, and the standards recommended by the Boston Board of Fire
       Underwriters, and shall, at Tenant's expense, obtain all permits,
       licenses and the like required by applicable law provided that Tenant
       shall not be required to make any alterations or improvements to the
       Premises to comply with such requirements if such requirements are
       applicable to the Building in general and not specifically because of
       Tenant's occupancy thereof.

       (b)    if repairs are required to be made by Tenant pursuant to
       the terms hereof, Landlord may demand that Tenant make the same
       forthwith, and if Tenant refuses or neglects to commence such
       repairs and complete the same with reasonable dispatch, after such
       demand, Landlord may (but shall not be obligated to do so) make or
       cause such repairs to be made and the costs thereof shall be paid
       solely by Tenant.

<PAGE>

       Tenant's expense in settings sufficient, in Landlord's reasonable
       judgment, to absorb and prevent vibration, noise and annoyance.  Tenant
       shall not move any safe, heavy machinery, heavy equipment, freight, bulky
       matter or fixtures within, into or out of the Building without the prior
       consent of Landlord, which consent will not be unreasonably withheld or
       delayed.

7.4    BUILDING SERVICES.  Landlord is obligated to provide:

            (i)   Passenger elevator service in common with Landlord and other
       tenants in the Building which service is to be available 24 hours a day,
       365 days a year.

            (ii)  Cleaning and janitorial services including rubbish
            removal, to the Premises, provided the same are kept in
            reasonable order by Tenant, in accordance with the cleaning
            standards set forth in Schedule CS attached hereto.  If extra
            services are necessary by reason of any special installations
            made by Tenant, Tenant shall pay Landlord the cost thereof as
            an additional charge promptly after receipt of a bill therefor.

            6:00 p.m. and on Saturdays from 9:00 a.m. to 12:00 p.m. and access
            at all other times subject to reasonable security restrictions from
            time to time in effect, and subject always to restrictions based on
            emergency conditions.  Landlord shall provide, at Tenant's expense,
            keys or other security device which will permit such access outside
            of the hours and days above specified.

            (iv)  Cleaning and janitorial services to the Common Areas, the

            walkways included in the Property, all so as to maintain such areas
            in a clean and neat condition commensurate with other first class
            office buildings in the metropolitan Boston area.

7.5    UTILITIES.(a) To the extent utility services to the Premises are
       separately metered, the Tenant shall pay when due, directly to the
       supplier of such utilities, all charges for utility services provided to
       the Premises including, without limitation, electricity, gas, water,
       telephone, and the facilities to heat or air-condition the Premises; If
       such utility services are not separately metered, or if such utility
       services serve Common Areas, Tenant shall promptly pay Tenant's
       Proportionate Share of same upon being billed therefor by the Landlord.
       If water consumed by the Tenant is not metered separately from water
       consumed by the


                                       15

<PAGE>

       remainder of the Building, Tenant shall pay to Landlord, upon being
       billed therefor by Landlord, Tenant's Proportionate Share of the
       aforesaid.  The aforementioned share is based on the assumption that
       water in the Premises will be used only for ordinary drinking and
       lavatory purposes.  If water is consumed in the Premises for other
       purposes or in excessive quantities, then Tenant shall pay to Landlord,
       on demand from time to time, charges for said additional water as
       reasonably estimated by Landlord.  Landlord reserves the right to install
       a water meter to measure water consumption in the Premises if not
       installed at the Commencement Date.  If any other utility is not
       separately metered for the Premises, or serves common areas of the
       Building or Land Parcel, Tenant shall pay Tenant's Proportionate Share in
       accordance herewith.

       (b)  The Landlord shall be responsible for the effecting
       maintenance and repair of all heating, ventilation, and air-
       conditioning equipment directly serving the Tenant, and Tenant
       shall pay to Landlord within thirty (30) days of invoice therefor
       all costs connected with such maintenance and repair.

       (c)  The Landlord shall not be liable for any interruption of
       electricity, gas, water, telephone, sewage and/or septic system,
       heating, air conditioning or other utility service supplied to the
       Premises unless caused by the gross negligence of Landlord and
       Landlord reserves the right to stop any service or utility to the
       Premises, when in Landlord's judgment it is deemed necessary by
       reason of accident, emergency or repair work.  No such
       interruption or stoppage of utility service shall be deemed to be
       an eviction of the Tenant or relieve Tenant from any of the
       Tenant's obligations under this lease.


                                  ARTICLE VIII

                           OPERATING AND TAX EXPENSES

8.1    DEFINITIONS.  For the purposes of this Article, the following terms shall
       have the following respective meanings:

            Operating Year:  Each calendar year (or other twelve-month
       period as determined by Landlord) in which any part of the Term of
       the Lease shall fall.

            Operating Expenses:  The aggregate costs or expenses
       reasonably incurred by Landlord with respect to the operation,
       cleaning, repair, maintenance and management of the Property as
       more particularly enumerated in Exhibit OC attached hereto,
       provided that, if during any


                                       16

<PAGE>

       portion of the Operating Year for which Operating Expenses are being
       computed, the Building is not operated or less than all of Building
       Rentable Area is occupied by tenants or if Landlord is not supplying all
       tenants with the services being supplied hereunder, actual Operating
       Expenses incurred shall be reasonably and equitably projected by Landlord
       to be the estimated Operating Expenses that would have been incurred if
       all of Building Rentable Area were occupied for such Year and such
       services were being supplied to all tenants, and such projected amount
       shall, for the purposes hereof, be deemed to be the Operating Expenses
       for such Year.  In no event, however, shall Tenant's share of Operating
       Expenses exceed its Proportionate Share of a fully occupied building.

            Taxes:  The real estate taxes assessed with respect to the
       Property and/or any other tax if the same replaces the current

       to the Property and is generally applicable to owners of similar
       properties.

            Operating and Tax Expenses:  The aggregate of the Operating
       Expenses and Taxes.

8.2    TENANT'S PAYMENTS.(a) During the Term, Tenant shall pay to Landlord As
       Additional Rent Tenant's Proportionate Share of Operating and Tax
       Expenses, which amount shall be apportioned for any operating Year in
       which the Commencement Date falls or the Term of this Lease ends.  Tenant
       shall also pay to Landlord in twelve (12) equal monthly installments
       commencing on the Commencement Date and payable in advance on the first
       (1st) day of each calendar month during the Term, a management fee equal
       to three percent (3%) of Base Rent (as the same is adjusted as provided
       herein) owed by Tenant to Landlord under the terms of this Lease.  Such
       fee shall be due on the first (1st) of each month by check made payable
       to Atlantic Realty and Development, Inc. at 24 New England Executive
       Park, Burlington, Massachusetts 01803.  The management fee shall be pro-
       rated for any partial month.

       (b)  Estimated payments by Tenant on account of Operating and Tax
       Expenses shall be made monthly on the first day of each and every
       calendar month during the Term of this Lease and otherwise in the manner
       herein provided for the payment of Base Rent.  The monthly amount so to

       each Operating Year a sum equal to Tenant's required payments, as
       reasonably estimated by Landlord (based on the budget supplied to Tenant
       by Landlord) from time to time during each operating Year, on account of
       Operating and Tax Expenses for such Operating Year.  Within 180 days
       after the end of each operating Year, Landlord shall submit to Tenant a
       reasonably detailed accounting of Operating and Tax Expenses for such


                                       17

<PAGE>

       Operating Year prepared in accordance with generally accepted accounting
       practices and principles and certified by a representative of Landlord.
       If estimated payments theretofor made for such Operating Year by Tenant
       exceed Tenant's required payment on account thereof for such Operating
       Year, according to such statement, Landlord shall credit the amount of
       overpayment against the next following monetary obligations of Tenant to
       Landlord under this Lease, and thereafter against Tenant's subsequent
       monetary obligations until such overpayment is fully applied against such
       monetary obligations (or promptly refund such overpayment if the Term of
       this Lease has ended and Tenant has no further obligation to Landlord);
       and, if the required payments on account thereof for such year are
       greater than the estimated payments (if any) theretofor made on account
       thereof for such Operating Year, Tenant shall promptly make payment to
       Landlord within twenty-five (25) days after being so advised by Landlord.

       (c)  Landlord shall at all times keep proper books of record and
       account in accordance with generally accepted accounting
       principles and practices, applied on a consistent basis, in which
       full, true and accurate entries shall be made of all operating and
       Tax Expenses for each Operating Year, and shall maintain for the
       same periods all contracts, instruments and other records with
       respect to Operating and Tax Expenses for each such Year.
       Landlord shall permit Tenant and Tenant's agent, at Tenant's
       expense, by appointment and during normal business hours, to
       review Landlord's records, books and accounts of the Building and
       any audited statements thereof relating to Operating and Tax
       Expenses for such Operating Year for the purpose of verifying
       operating and Tax Expenses and any accounting which Landlord is
       required to provide hereunder.  Such books of record shall be
       retained by Landlord for two (2) years after Landlord delivers the
       accounting for the applicable Operating Year.

8.3    ABATEMENT.(a) If Landlord shall receive any tax abatement refund or
       reimbursement of Taxes, then after deducting Landlord's unpaid expenses
       reasonably incurred in obtaining the same, Landlord shall pay to Tenant
       Tenant's Proportionate Share of such refund or reimbursement; provided
       that Landlord shall have the right to deduct from any such amount the
       amount of any payments which are then due and payable from Tenant.

       (b)  Provided that tenants who occupy not less than fifty percent
       (50%) of the Building Rentable Area including Tenant request
       Landlord in writing so to do (which requests are received not less
       than seven (7) days prior to the last date on which real estate
       tax abatement proceedings for a particular year may be commenced),
       Landlord will institute and prosecute proceedings for an abatement
       of Taxes for such year.  The manner and method of conducting such
       proceedings shall be solely within the reasonable judgment of
       Landlord provided that the obligation of Landlord


                                       18

<PAGE>

       to prosecute such proceedings shall not be applicable to any proceeding
       beyond the Appellate Tax Board.  From time to time, within ten (10) days
       of Landlord's notice, Tenant shall pay to Landlord, as an additional
       charge, Tenant's Proportionate Share of the reasonable cost and expense
       of such proceedings.  If Tenant, or any other tenant, shall fail to make
       any such payment within such ten (10) days period, Landlord shall
       thereafter be free from any further obligations under this paragraph.  In
       the event that Landlord is successful in obtaining an abatement, any
       costs theretofore advanced by Tenant shall (to the extent of the amount
       of the refund) be repaid to Tenant and shall be deemed a cost of Landlord
       in obtaining such refund for the purposes of paragraph (a) hereof.


                                   ARTICLE IX

                    INDEMNITY AND PUBLIC LIABILITY INSURANCE

9.1    TENANT'S INDEMNITY.  To the maximum extent this agreement may be made
       effective according to law, Tenant agrees to indemnify and save harmless
       Landlord from and against all claims of whatever nature arising (i) from
       any accident, injury or damage whatsoever to any person, or to the
       property of any person, occurring on or about the Premises or (ii) from
       any accident, injury or damage occurring outside of the Premises but on
       the Property, in each case where such accident, damage or injury results
       from an act or omission on the part of Tenant or Tenant's agents or
       employees or independent contractors or visitors and, in either case,
       occurring after the date of this Lease until the end of the Term of this
       Lease and thereafter so long as Tenant is in occupancy of any part of the
       Premises unless such accident, damage or injury is caused by the
       negligence or misconduct of Landlord or its employees, agents or
       contractors or assigns.  This indemnity and hold harmless agreement shall
       include indemnity against all costs, expenses and liabilities incurred in
       or in connection with any such claim or proceeding brought thereon, and
       the defense thereof, including, without limitation, reasonable attorneys'
       fees at both the trial and appellate levels.

9.2    PUBLIC LIABILITY INSURANCE.  Tenant agrees to maintain in full force from
       the date upon which Tenant first enters the Premises for any reason,
       throughout the Term of this Lease, and thereafter so long as Tenant is in
       occupancy of any part of the Premises, a policy of general liability and
       property damage insurance (including broad form contractual liability,
       independent contractor's hazard and completed operations coverage) under
       which Tenant is named as an insured and Landlord (and such other persons
       as are in privity of estate with Landlord as may be set forth in


                                       19

<PAGE>

       a notice from time to time) is named as an additional insured, and under
       which the insurer agrees to indemnify and hold Landlord, and those in
       privity of estate with Landlord (as may be set forth in a notice from
       time to time), harmless from and against all cost, expense and/or
       liability arising out of or based upon any and all claims, accidents,
       injuries and damages set forth in Section 9.1.  Each such policy shall be
       non-cancellable and non-amendable with respect to Landlord and Landlord's
       said designees without thirty (30) days' prior notice and shall be in at
       least the amounts of the Initial Public Liability Insurance specified in
       Section 1.1 or such greater amounts as Landlord shall from time to time
       reasonably request, and a duplicate original or certificate thereof shall
       be delivered to Landlord.

9.3    TENANT'S RISK.  To the maximum extent this agreement may be made
       effective according to law, Tenant agrees that all of the furnishings,
       fixtures, equipment, effects and property of every kind, nature and
       description of Tenant and all persons claiming by, through or under
       tenant which, during the term of this Lease or any occupancy of the
       Premises by Tenant or anyone claiming under Tenant, may be on the
       Premises or elsewhere on the Property, shall be at the sole risk and
       hazard of Tenant, and if the whole or any part thereof shall be destroyed
       or damaged by fire, water or otherwise, or by the leakage or bursting of
       water pipes or sprinklers, by theft or from any other cause, no part of
       said loss of damage is to be charged to or be borne by Landlord unless
       due to the negligence or misconduct of Landlord, its employees, agents,
       or contractors.  Tenant shall carry "all-risk" property insurance
       (including so-called improvements and betterments) covering such
       furnishings, fixtures, equipment, effects and property, and the policies
       evidencing such insurance shall provide for a waiver of subrogation as
       required in section 9.5.

9.4    INJURY CAUSED BY THIRD PARTIES.  To the maximum extent this agreement may
       be made effective according to law, Tenant agrees that Landlord shall not
       be responsible or liable to Tenant, or to those claiming by, through or
       under Tenant, for any loss or damage that may be occasioned by or through
       the acts or omissions of persons other than Landlord and Landlord's
       employees, agents and contractors.

9.5    WAIVER OF SUBROGATION.  Insofar as, and to the extent that, the following
       provision shall not make it impossible to secure insurance coverage
       obtainable from responsible insurance companies doing business in the
       locality in which the Property is located (even though extra premium may
       result therefrom) Landlord and Tenant mutually agree that any property
       damage insurance, carried by either shall provide for the waiver by the
       insurance carrier of any right of subrogation against the other, and they
       further mutually agree that, with respect to any damage to property, the
       loss from which is covered by insurance then being carried by them,
       respectively, the one carrying such insurance and suffering such loss
       releases the other of and from any and all claims with respect to such
       loss to the extent of the insurance proceeds paid with respect thereto.

                                    ARTICLE X

                           FIRE, EMINENT DOMAIN, ETC.

10.1   ABATEMENT OF RENT.  If the Premises shall be damaged by fire or other
       casualty, Base Rent and Tenant's Share of operating and Tax Expenses
       payable by Tenant shall abate proportionately for the period in which, by
       reason of such damage, there is material interference with Tenant's use
       of the Premises, having regard to the extent to which Tenant may be
       required to discontinue Tenant's use of all or a portion of the Premises,
       but such abatement or reduction shall end if and when Landlord shall have
       substantially restored the Premises (excluding any alterations, additions
       or improvements made or to be made by Tenant) to the condition in which
       they were prior to such damage.  If the Premises shall be affected by any
       exercise of the power of eminent domain, Base Rent and Tenant's Share of
       Operating and Tax Expenses payable by Tenant shall be justly and
       equitably abated and reduced according to the nature and extent of the
       loss of use thereof suffered by Tenant.  In no event shall Landlord have
       any liability for damages to Tenant for inconvenience, annoyance or
       interruption of business arising from such fire, casualty or eminent
       domain.

10.2   RIGHTS OF TERMINATION.  Within thirty (30) days from the date of damage
       by fire or other casualty, Landlord shall notify Tenant whether or not
       the Premises can be materially restored within one hundred and eighty
       (180) days from the date of such damage, and Landlord's reasonable
       determination shall be binding on Tenant.  For purposes hereof, the
       Building or Premises shall be deemed "materially restored" if they are in
       such condition as would not prevent or materially interfere with Tenant's
       use of the Premises for the purpose for which it was then being used.  If
       such repairs cannot, in Landlord's reasonable estimation, be made within
       one hundred and eighty (180) days, Landlord and Tenant shall each have
       the option of giving the other, at any time after giving such notice,
       notice terminating this Lease as of the date of such damage.  In the
       event of the giving of such notice, this Lease shall expire and all
       interest of the Tenant in the Premises shall terminate as of the date of
       such notice as if such date had been originally fixed in this Lease for
       the expiration of the Term.

10.3   RESTORATION.  In the event that neither Landlord nor Tenant exercises the
       above set forth option to terminate this Lease in the event of damage by
       fire or other casualty then Landlord shall repair or restore such damage
       to the extent Landlord receives insurance proceeds for such repair or
       restoration, this Lease continuing in full force and effect, with the
       Rent hereunder to be equitably abated as herein above provided.  In the
       event that Landlord notifies Tenant that the Premises can be materially
       restored within one hundred eighty days (180) from the date of damage by
       fire or other casualty pursuant to Section 10.2 and Landlord fails to
       materially restore the Premises within such one hundred eighty


                                       21

<PAGE>

       (180) day period, then Tenant shall be entitled to terminate this Lease
       by giving Landlord thirty (30) days prior written notice of such
       termination.  In the event that Landlord fails to complete such material
       restoration of the Premises within thirty (30) days of receipt of
       Tenant's notice to terminate as set forth above, then this Lease shall
       expire at the end of such thirty (30) days and all interest of the Tenant
       in the Premises shall terminate as of such date as if such date had been
       originally fixed in this Lease for the expiration of the Term.  Landlord
       shall not be required to repair any damage by fire or other cause, or to
       make any repairs or replacements of any alterations, additions or
       improvements installed in the Premises by Tenant.  Notwithstanding
       anything to the contrary contained in this Article, (a) Landlord shall
       not have any obligation whatsoever to repair, reconstruct, or restore the
       Premises when the damages resulting from any casualty covered by the
       provisions of this Article occur during the last twelve (12) months of
       the Term, and (b) in the event the holder of any, indebtedness secured by
       a mortgage or deed of trust covering the Premises or Building or any
       superior Lessor, as defined in Section 12.14 hereof, requires that any
       insurance proceeds be applied to such indebtedness or to amounts owing to
       such Superior Lessor, then Landlord shall have the right to terminate
       this Lease by delivering written notice of termination to Tenant within
       thirty (30) days after such requirement is made by any such holder,
       whereupon this Lease shall end on the date of such notice as if the date
       of such notice were the date originally fixed in this Lease for the
       expiration of the Term.

10.4   EMINENT DOMAIN.  If possession of all or any substantial part of the
       Premises shall be taken by any public or quasi-public authority under the
       power of eminent domain, or conveyance in lieu thereof, either party
       hereto shall have the right, at its option, of giving the other, at any
       time within thirty (30) days after such taking, notice terminating this
       Lease.  If neither party hereto shall so elect to terminate this Lease,
       Rent shall be adjusted equitably.  Before Tenant may terminate this Lease
       by reason of taking or appropriation as above provided, such taking or
       appropriation shall be so substantial as to materially interfere with
       Tenant's use and occupancy thereof or shall make unusable for Tenant's
       purposes more than twenty five percent of the Premises.  In addition to
       the rights of Landlord above, if any substantial part of the Building
       shall be taken or appropriated by any public or quasi-public authority
       under the power of eminent domain, or conveyance in lieu thereof, and
       regardless of whether the Premises or any part thereof are so taken or
       appropriated, Landlord shall have the right at its sole option, to
       terminate this Lease.

10.5   AWARD.  Landlord shall have and hereby reserves and expects, and Tenant
       hereby grants and assigns to Landlord, all rights to recover for damages
       to the Property and the leasehold interest hereby created, and to
       compensation accrued or hereafter to accrue by reason of such taking,
       damage or destruction, and by way of confirming the foregoing, Tenant
       hereby grants and assigns, and covenants



                                       22

<PAGE>

       with Landlord to grant and assign to Landlord, all rights to such damages
       or compensation; provided, however, if any such damages or compensation
       award expressly includes an amount for Tenant's Removable Property or
       Tenant's moving expenses, Landlord shall pay such amount to Tenant
       promptly after its receipt thereof.  Nothing contained herein shall be
       construed to prevent Tenant from prosecuting in any condemnation
       proceedings a claim for the value of any of Tenant's Removable Property
       installed in the Premises by Tenant at Tenant's expense and for
       relocation expenses, provided that such action shall not affect the
       amount of compensation otherwise recoverable by Landlord from the taking
       authority.


                                   ARTICLE XI

                                     DEFAULT

11.1   TENANT'S DEFAULT. (a) If at any time subsequent to the date of this Lease
       any one or more of the following events (herein referred to as a "Default
       of Tenant") shall happen:

            (i)   Tenant shall fail to pay the Base Rent when due and such
            failure shall continue for five (5) full Business Days after notice
            to Tenant from Landlord;

            (ii)  Tenant shall fail to pay Tenant's Proportionate Share of
            operating and Tax Expenses or other charges hereunder when due and
            such failure shall continue for ten (10) full Business Days after
            notice to Tenant from Landlord; or

            (iii) Tenant shall neglect or fail to perform or observe any other
            covenant herein contained on Tenant's part to be performed or
            observed and Tenant shall fail to remedy the same as soon as
            practicable and in any event within thirty (30) days after notice to
            Tenant specifying such neglect or failure, or if such failure is of
            such a nature that Tenant cannot reasonably remedy the same within
            such thirty (30) day period, Tenant shall fail to commence promptly
            (and in any event within such thirty (30) day period) to remedy the
            same and to prosecute such remedy to completion with diligence and
            continuity; or

            (iv)  Tenant's leasehold interest in the Premises shall be taken on
            execution or by other process of law directed against Tenant; or

            (v)   Tenant shall make an assignment for the benefit of creditors
            or shall file a voluntary petition in bankruptcy or shall be
            adjudicated bankrupt or


                                       23

<PAGE>

            insolvent, or shall file any petition or answer seeking any
            reorganization, arrangement, composition, readjustment, liquidation,
            dissolution or similar relief for itself under any present or future
            Federal, State or other statute, law or regulation for the relief of
            debtors, or shall seek or consent to or acquiesce in the appointment
            of any trustee, receiver or liquidator of Tenant or of all or any
            substantial part of its properties, or shall admit in writing its
            inability to pay its debts generally as they become due; or

            (vi)  A petition shall be filed against Tenant in bankruptcy or
            under any other law seeking any reorganization, arrangement,
            composition, readjustment, liquidation, dissolution, or similar
            relief under any present or future Federal, State or other statute,
            law or regulation and shall remain undismissed or unstayed for an
            aggregate of sixty (60) days (whether or not consecutive), or if any
            debtor in possession (whether or not Tenant) trustee, receiver or
            liquidator of Tenant or of all or any substantial part of its
            properties or of the Premises shall be appointed without the consent
            or acquiescence of Tenant and such appointment shall remain
            unvacated or unstayed for an aggregate of ninety (90) days (whether
            or not consecutive); or

            (vii) If a Default of Tenant of the kind set forth in clauses (i)
            and (ii) above shall occur and Tenant shall cure such Default within
            the applicable grace period and an event which would constitute a
            similar Default after the applicable grace period shall occur more
            than twice within the next 365 days, whether or not such similar
            Default is cured within the applicable grace period;

       then, in any such case, Landlord may terminate this Lease by notice to
       Tenant, specifying a date not less than ten (10) full Business Days after
       the giving of such notice on which this Lease shall terminate and this
       Lease shall come to an end on the date specified therein as fully and
       completely as if such date were the date herein originally fixed for the
       expiration of the Term of this Lease (Tenant hereby waiving any rights of
       redemption under Massachusetts General Laws c. 186 11) , and Tenant will
       then quit and surrender the Premises to Landlord, but Tenant shall remain
       liable as hereinafter provided.

       (b)  If this Lease shall have been terminated as provided in this
       Article, or if any execution or attachment shall be issued against Tenant
       or any Tenant's property whereupon the Premises shall be taken or
       occupied by someone other than Tenant, then Landlord may, without notice,
       re-enter the Premises, either by force, summary proceedings, ejectment or
       otherwise, and remove and dispossess Tenant and all other persons and any
       and all property from the same, as if this Lease had not been made, and
       Tenant hereby waives the service of notice of intention to re-enter or to
       institute legal proceedings to that end.


                                       24

<PAGE>

       (c)  In the event of any termination as provided in this Article, Tenant
       shall pay the Base Rent, Tenant's Share of operating and Tax Expenses and
       other sums payable hereunder up to the time of such termination, and
       thereafter Tenant, until the end of what would have been the Term of this
       Lease in the absence of such termination, and whether or not the Premises
       shall have been relet, shall be liable to Landlord for, and shall pay to
       Landlord, as liquidated current damages, the Base Rent, Tenant's Share of
       Operating and Tax Expenses and other sums which would be payable
       hereunder if such termination had not occurred, less the net proceeds, if
       any, of any reletting of the Premises, after deducting all reasonable
       expenses in connection with such reletting, including, without
       limitation, all repossession costs, brokerage commissions, legal
       expenses, attorneys' fees, advertising, expenses of employees, alteration
       costs and expenses of preparation for such reletting.  Tenant shall pay
       such current damages to Landlord monthly on the dates which the Base Rent
       would have been payable hereunder if this Lease had not been terminated.

       (d)  At any time after such termination, whether or not Landlord shall
       have collected any current damages as set forth in paragraph (c), as
       liquidated final damages and in lieu of all such current damages beyond
       the date of such demand, at Landlord's election Tenant shall pay to
       Landlord an amount equal to the excess, if any, of the Base Rent,
       Tenant's Share of Operating and Tax Expenses and other sums as
       hereinbefore provided which would be payable hereunder from the date of
       such demand (assuming that, for the purposes of this paragraph, annual
       payments by Tenant on account of operating and Tax Expenses would be the
       same as the payments required for the Operating Year immediately
       preceding such demand) for what would be the then unexpired Term of this
       Lease if the same remained in effect, discounted to present value at a
       rate of 8% per year, over the then fair net rental value of the Premises
       for the same period, also discounted to present value at a rate of 8% per
       year.

       (e)  With respect to the remedies set forth in the foregoing paragraphs
       (c) and (d), if such termination occurs prior to the date by which the
       Tenant is obligated to provide the Termination Notice as set forth in
       paragraph 13.1 hereof describing the Tenant Cancellation Option, such
       termination shall be deemed to occur on the Termination Date (as that
       term is defined in said paragraph 13.1), provided Tenant pays to Landlord
       the Termination Fee set forth in paragraph 13.1 within fifteen (15) days
       of Tenant's receipt of Landlord's Notice of termination as set forth in
       paragraph 11.1(a).  If Tenant fails to pay the Termination Fee, or if
       such termination occurs after the Termination Date and Tenant had not
       exercised its Cancellation option in the manner and upon the time frames
       established in said paragraph 13.1, such termination shall be deemed to
       occur on the date specified for expiration of the Lease in paragraph 1.1
       hereof, without regard to the Tenant Cancellation Option.


                                       25

<PAGE>

       (f)  In case of any Default by Tenant, re-entry, expiration and
       dispossession by summary proceedings or otherwise, Landlord may (i) re-
       let the Premises or any part or parts thereof, either in the name of
       Landlord or otherwise, for a term or terms which may at Landlord's option
       be equal to or less than or exceed the period which would otherwise have
       constituted the balance of the Term of this Lease and may grant
       concessions or free rent to the extent that Landlord considers advisable
       and necessary for the purpose of reletting the Premises; and such actions
       and the making of any alterations, repairs and decorations to the
       Premises in connection therewith shall not operate or be construed to
       release Tenant from liability hereunder as aforesaid.  Landlord shall in
       no event be liable in any way whatsoever for failure to re-let the
       Premises, or, in the event that the Premises are re-let, for failure to
       collect the rent under such re-letting.  Tenant hereby expressly waives
       any and all rights of redemption granted by or under any present or
       future laws in the event of Tenant being evicted or dispossessed, or in
       the event of Landlord obtaining possession of the Premises, by reason of
       the violation by Tenant of any of the covenants and conditions of this
       Lease.

       (g)  The specified remedies to which Landlord may resort hereunder are
       not intended to be exclusive of any remedies or means of redress to which
       Landlord may at any time be entitled lawfully, and Landlord may invoke
       any remedy (including the remedy of specific performance) allowed at law
       or in equity as if specific remedies were not herein provided for.

       (h)  All costs and expenses incurred by or on behalf of Landlord
       (including, without limitation, reasonable attorneys' fees and expenses
       at both the trial and appellate levels) in enforcing its rights hereunder
       in connection with any Default of Tenant shall be paid by Tenant;
       provided, however, if any legal proceeding is required to be brought to
       enforce the terms of this paragraph, or to challenge such enforcement,
       the prevailing party shall be entitled to reasonable attorneys' fees and
       expenses of litigation or arbitration in addition to any other relief to
       which it may be entitled.

       (i)  If a Guarantor of this Lease is named in Section 1.1, the happening
       of any of the events described in paragraphs (a)(v) or (a)(vi) of this
       Section 11.1 with respect to the Guarantor shall constitute a Default of
       Tenant hereunder.

11.2   LANDLORD'S DEFAULT.  Landlord shall in no event be in default in the
       performance of any of Landlord's obligations hereunder unless and until
       Landlord shall have failed to perform such obligations within thirty (30)
       days, or such additional time as is reasonably required to correct any
       such default or, in the event of an emergency as soon as reasonably
       possible, after notice by Tenant to Landlord specifying wherein Landlord
       has failed to perform any such obligations.  All costs and expenses
       incurred by or on behalf of Tenant (including, without limitation,
       reasonable attorneys' fees and expenses at both the trial and appellate

       levels) in enforcing its rights hereunder in connection with any Default
       of Landlord shall be paid by Landlord; provided, however, if any legal
       proceeding is required to be brought to enforce the terms of this
       paragraph or to challenge such enforcement, the prevailing party shall be
       entitled to reasonable attorneys' fees and expenses of litigation or
       arbitration in addition to any other relief to which it may be entitled.


                                   ARTICLE XII

                            MISCELLANEOUS PROVISIONS

12.1   EXTRA HAZARDOUS USE.  Tenant covenants and agrees that Tenant will not do
       or permit anything to be done in or upon the Premises, or bring in
       anything or keep anything therein, which shall increase the rate of
       property or liability insurance on the Premises or the Property above the
       standard rate applicable to Premises being occupied for Permitted Uses;
       and Tenant further agrees that, in the event that Tenant shall do any of
       the foregoing, Tenant will promptly pay to Landlord, on demand, any such
       increase resulting therefrom, which shall be due and payable as an
       additional charge hereunder.

12.2   WAIVER. (a) Except as otherwise expressly provided for in this Lease,
       failure on the part of Landlord or Tenant to complain of any action or
       non-action on the part of Tenant or Landlord, no matter how long the same
       may continue, shall never be a waiver by Landlord or by Tenant of any
       rights hereunder.  Further, no waiver at any time of any of the
       provisions hereof by Landlord or by Tenant shall be construed as a waiver
       of any of the other provisions hereof, and a waiver at any time of any of
       the provisions hereof shall not be construed as a waiver at any
       subsequent time of the same provisions.  The consent or approval of
       Landlord or Tenant to or of any action requiring such consent or approval
       shall not be construed to waive or render unnecessary Landlord's or
       Tenant's consent or approval to or of any subsequent similar act by the
       other.

       (b)  No payment by Tenant, or acceptance by Landlord, of a lesser amount
       than shall be due from Tenant to Landlord shall be treated otherwise than
       as a payment on account of the earliest installment of any payment due
       from Tenant under the provisions hereof.  The acceptance by Landlord of a
       check for a lesser amount with an endorsement or statement thereon, or
       upon any letter accompanying such check, that such lesser amount is
       payment in full, shall be given no effect, unless agreed upon in writing
       between Landlord and Tenant, and Landlord may accept such check without
       prejudice to any other rights or remedies which Landlord may have against
       Tenant.


                                       27

12.3   COVENANT OF QUIET ENJOYMENT.  Tenant, subject to the terms and provisions
       of this Lease, on payment of the Base Rent and Tenant's Share of
       operating and Tax Expenses and observing, keeping and performing all of
       the other terms and provisions of this Lease on Tenant's part to be
       observed, kept and performed, all within any applicable grace period
       allowed in this Lease, shall lawfully, peaceably and quietly have, hold,
       occupy and enjoy the Premises during the term hereof without hindrance or
       ejection by Landlord or persons lawfully claiming by, through or under
       Landlord.  The foregoing covenant of quiet enjoyment is in lieu of any
       other covenant, express or implied.

12.4   LANDLORD'S LIABILITY. (a) Tenant specifically agrees to look solely to
       Landlord's then equity interest in the Property at the time owned for
       recovery of any judgment from Landlord; it being specifically agreed that
       (i) Landlord shall have no liability for any claims accruing other than
       during the period of Landlord's ownership of the Property and (ii)
       neither Landlord (original or successor) nor any partner, trustee, agent,
       consultant, officer, stockholder, director, employee, or beneficiary of
       Landlord, nor any constituent person or entity of Landlord, shall ever be
       personally liable for any such judgment, or for the payment of any
       monetary obligation to Tenant.  The provision contained in the foregoing
       sentence is not intended to, and shall not, limit any right that Tenant
       might otherwise have to obtain injunctive relief against Landlord or
       Landlord's successors in interest, or to take any action not involving
       the personal liability of Landlord (original or successor).

       (b)  With respect to any services or utilities to be furnished by
       Landlord to Tenant, Landlord shall in no event be liable for failure to
       furnish the same when prevented from doing so by strike, lockout,
       breakdown, accident, order or regulation of or by any governmental
       authority, or failure of supply or failure whenever and for so long as
       may be necessary by reason of the making of necessary or emergency
       repairs or changes which Landlord is required or is permitted by this
       Lease or by law to make or in good faith deems necessary, or inability by
       the exercise of reasonable diligence to obtain supplies, parts or
       employees necessary to furnish such services, or because of war or other
       emergency, or for any other cause beyond Landlord's reasonable control,
       or for any cause due to any act or neglect of Tenant or Tenant's
       servants, agents, employees, licensees or any person claiming by, through
       or under Tenant.

       (c)  In no event shall Landlord ever be liable to Tenant for any loss of
       business or any other indirect or consequential damages suffered by
       Tenant from whatever cause.

       (d)  With respect to any repairs or restoration which are required or
       permitted to be made by Landlord, the same may be made during normal
       business hours


                                       28

<PAGE>

       and Landlord shall not have any liability for damages to Tenant for
       inconvenience, annoyance or interruption of business arising therefrom.

12.5   NOTICE TO AND RIGHTS OF MORTGAGEE OR GROUND LESSOR.  After receiving
       notice from any person, firm or other entity that it holds a mortgage or
       a ground lease which includes the Premises, no notice from Tenant to
       Landlord shall be effective unless and until a copy of the same is given
       to such holder or ground lessor (provided Tenant shall have been
       furnished with the name and address of such holder or ground lessor), and
       the curing of any of Landlord's defaults by such holder or ground lessor
       shall be treated as performance by Landlord.  Tenant agrees that if
       Landlord shall have failed to cure any default of Landlord within the
       time provided for in this Lease, then such holder or ground lessor shall
       have an additional thirty (30) days within which to cure such default or,
       if such default cannot be cured within that time, then such additional
       time as may be necessary provided that within such thirty (30) days such
       holder or ground lessor has commenced and is diligently pursuing the
       remedies necessary to cure such default, (including but not limited to
       commencement of foreclosure proceedings, if necessary to effect such
       cure) in which event this Lease shall not be terminated while such
       remedies are being so diligently pursued.

12.6   ASSIGNMENT OF RENTS AND TRANSFER OF TITLE.  In the event of a transfer of
       Landlord's interest in the Property by Landlord, Landlord shall from the
       date of such transfer be entirely freed and relieved from the performance
       and observance of all covenants and obligations hereunder accruing
       thereafter.

12.7   RULES AND REGULATIONS.  Tenant shall abide by reasonable rules and
       regulations from time to time established by Landlord (provided that the
       same do not diminish Tenant's rights under this Lease), and of which
       Tenant has been given notice, it being agreed that such rules and
       regulations will be applied by Landlord in a non-discriminatory fashion,
       such that all rules and regulations shall be generally applicable to
       other office tenants of the Building.  Landlord agrees to use reasonable
       efforts to insure that any such rules and regulations are so uniformly
       enforced, but Landlord shall not be liable to Tenant for violation of the
       same by any other tenant or occupant of the Building, or persons having
       business with them.  In the event that there shall be a conflict between
       such rules and regulations and this Lease, the provisions of this Lease
       shall prevail.

12.8   INVALIDITY OF PARTICULAR PROVISIONS.  If any term or provision of this
       Lease, or the application thereof to any person or circumstance shall, to
       any extent, be invalid or unenforceable, the remainder of this Lease, or
       the application of such term or provision to persons or circumstances
       other than those as to which it is held invalid or unenforceable, shall
       not be affected thereby, and


                                       29

<PAGE>

       each term and provision of this Lease shall be valid and be enforced to
       the fullest extent permitted by law.

12.9   PROVISIONS BINDING, ETC.  Except as herein otherwise provided, the terms
       hereof shall be binding upon and shall inure to the benefit of the
       successors and assigns, respectively, of Landlord and Tenant and, if
       Tenant shall be an individual, upon and to his heirs, executors,
       administrators, successors and assigns.  Each term and each provision of
       this Lease to be performed by Tenant shall be construed to be both a
       covenant and a condition.  The reference contained to successors and
       assigns of Tenant is not intended to constitute a consent to assignment
       by Tenant.

12.10  RECORDING.  Tenant agrees not to record this Lease, but, if the Term of
       this Lease (including any extended term) is seven (7) years or longer,
       each party hereto agrees, on the request of the other, to execute a so-
       called notice of lease in recordable form, complying with applicable law
       and reasonably satisfactory to Landlord's attorneys.  In no event shall
       such document set forth the rent or other charges payable by Tenant under
       this Lease; and any such document shall expressly state that it is
       executed pursuant to the provisions contained in this Lease, and is not
       intended to vary the terms and conditions of this Lease. if this Lease is
       terminated prior to the Lease expiration date set forth in such notice of
       lease, each party hereto agrees, on the request of the other, to execute
       and deliver a recordable certificate documenting such earlier termination
       date.

12.11  NOTICES.  Whenever, by the terms of this Lease, notices shall or may be
       given either to Landlord or to Tenant, such notice shall be in writing.
       All such notices shall be delivered in hand, sent by registered mail,
       postage prepaid, return receipt requested, or sent by an overnight
       express courier service which provides evidence of delivery or attempted
       delivery.:

       Secretary, Kaiser Aerospace and Electronics Corporation, 950 Tower Lane,
       Suite 800, Foster City, California 94404.

       All notices shall be effective on the day delivered provided the same is
       delivered on or before 5:00 p.m. on such day or on the following Business
       Day if not delivered on or before 5:00 P.M.

12.12  WHEN LEASE BECOMES BINDING.  The submission of this document for
       examination and negotiation does not constitute an offer to lease, or a
       reservation of, or option for, the Premises, and this document shall
       become effective and binding only upon the execution and delivery hereof
       by both Landlord and Tenant.  All negotiations, considerations,
       representations and understandings between Landlord and Tenant are
       incorporated herein and this Lease expressly supersedes any proposals or
       other written documents relating hereto.  This Lease may be modified or
       altered only by written agreement between Landlord and Tenant, and no act
       or omission of any employee or agent of Landlord shall alter, change or
       modify any of the provisions hereof.

12.13  PARAGRAPH HEADINGS.  The paragraph headings throughout this instrument
       are for convenience and reference only, and the words contained therein
       shall in no way be held to explain, modify, amplify or aid in the
       interpretation, construction or meaning of the provisions of this Lease.

12.14  RIGHTS OF MORTGAGEE OR GROUND LESSOR. (a) This Lease, and all rights of
       Tenant hereunder, are and shall be subject and subordinate to all
       mortgages and/or ground leases which may now or hereafter affect the
       Property whether or not such mortgages or leases shall also cover other
       lands and/or buildings, to each and every advance made or hereafter to be
       made under such mortgages, and to all renewals, modifications,
       replacements and extensions of such mortgages and leases and all
       consolidations of such mortgages, provided that, with respect to any such
       mortgage or lease hereafter placed on the Property, Landlord shall
       deliver to Tenant an agreement by such holder or lessor to the effect
       that, subject to qualifications of the type set forth in the second
       sentence of paragraph (b) hereof, all of Tenant's rights and Landlord's
       obligations hereunder shall be recognized by such holder or lessor.  Such
       subordination shall be automatic and without need for any additional
       action or documentation.  Without derogating from the foregoing, in
       confirmation of such subordination, and subject to the foregoing
       condition, Tenant shall promptly execute, acknowledge and deliver any
       instrument that Landlord, the holder of any such mortgage or the lessor
       under any such lease or any of their respective successors in interest
       may reasonably request to evidence such subordination.  Landlord agrees
       to request the holder of the existing mortgage on the Property to deliver
       an agreement by such holder to the effect that, subject to the
       qualifications of the type set forth in the second sentence of paragraph
       (b) hereof, that such holder recognizes all of Tenant's rights hereunder.
       Any mortgage to which this Lease is, at the time referred to, subject and
       subordinate, is herein called "Superior Mortgage" and the holder of a
       Superior Mortgage is herein called "Superior Mortgagee"; and any lease to
       which


                                       31

<PAGE>

       this Lease is at the time referred to, subject and subordinate is herein
       called "Superior Lease" and the lessor of a Superior Lease or its
       successor in interest, at the time referred to, is herein called
       "Superior Lessor".

       (b)  If any Superior Mortgagee or Superior Lessor or the nominee or
       designee of any Superior Mortgagee or Superior Lessor shall succeed to
       the rights of Landlord (for the purposes of this paragraph (b), the
       "Preceding Landlord") under this Lease, whether through possession or
       foreclosure action or delivery of a new lease or deed, or otherwise, then
       Tenant shall attorn to and recognize such party (herein called "Successor
       Landlord") so succeeding to the Preceding Landlord's rights as Tenant's
       landlord under this Lease and, upon such Successor Landlord's request,
       Tenant shall promptly execute and deliver any instrument that such
       Successor Landlord may reasonably request to evidence such attornment
       provided that such Successor Landlord gives Tenant a written agreement to
       accept Tenant's attornment and recognizes Tenant's rights under this
       Lease (subject to the qualifications hereinafter set forth).  Upon such
       attornment, this Lease shall continue in full force and effect as a
       direct lease between the Successor Landlord and Tenant upon all of the
       terms, conditions and covenants as are set forth in this Lease, except
       that the Successor Landlord (unless formerly the landlord under this
       Lease or its nominee or designee) shall not be (a) liable in any way to
       Tenant for any act or omission, neglect or default on the part of the
       Preceding Landlord under this Lease, (b) responsible for any monies owing
       by or on deposit with the Preceding Landlord to the credit of Tenant;
       provided, however, that Tenant shall be entitled to a credit for payments
       in advance of any Additional Rent as required hereunder, (c) subject to
       any counterclaim or setoff which theretofore accrued to Tenant against
       the Preceding Landlord, unless the same is specifically permitted under
       this Lease, (d) bound by any modification of this Lease subsequent to
       such Superior Mortgage or Lease which was not approved in writing by the
       Superior Mortgagee or Superior Lessor, or by any previous prepayment of
       Base Rent for more than one (1) month which was not approved in writing
       by the Superior Mortgagee or Superior Lessor thereto, (e) liable to the
       Tenant beyond the Successor Landlord's interest in the Property and the
       rents, income, receipts, revenues, issues and profits issuing from such
       Property, (f) responsible for the performance of any work to be done by
       the Preceding Landlord under this Lease to render the Premises ready for
       occupancy by the Tenant, (g) required to remove any person occupying the
       Premises or any part thereof, except if such person claims by, through or
       under the Successor Landlord.

12.15  ESTOPPEL CERTIFICATES.  Within fifteen (15) days following any written
       request which Landlord or Tenant (the "Requesting Party") may make from
       time to time to the other party hereto (the "Responding Party"), the
       Responding Party shall execute and deliver to the Requesting Party, any
       prospective purchaser, mortgagee or prospective mortgagee, ground lessor
       or prospective ground lessor, a sworn statement certifying as to: (a) the
       Commencement Date of this Lease,

<PAGE>

       (b) the fact that this Lease is unmodified or, if this Lease has been
       modified, the extent of such modification, was duly authorized and
       properly executed and delivered by the Responding Party and is in full
       force and effect (or, if there have been modifications hereto, that this
       Lease is in full force and effect, as modified (and attaching a copy of
       such modifications), that the Lease represents the entire agreement
       between Landlord and Tenant with respect to the Premises, (c) the date to
       which the Base Rent has been paid, the amount of such Base Rent, Tenant's
       Proportionate Share and Tenant's current monthly payments on account of
       estimated operating and Tax Expenses, (d) the fact that there are no
       current defaults under this Lease nor any events or conditions which,
       with the giving of notice or the lapse of time or both, would constitute
       a default, by the Responding Party or, to the best of the Responding
       Party's knowledge, the Requesting Party, except as specified in the
       Responding Party's statement, and that the Responding Party, to the best
       of the Responding Party's knowledge, has no existing defense, offsets,
       liens, claims or credits under this Lease or against any amounts payable
       under this Lease, (e) the extent to which any options to extend the Term
       or expand the Premises have been exercised by Tenant, (f) the amount of
       any Security Deposit held by Landlord, (g) the fact that Tenant has not
       assigned, pledged or transferred any interest in the Lease or sublet any
       portion of the Premises or, if Tenant has so assigned, pledged,
       transferred or sublet, the extent of such assignment, pledge, transfer or
       subletting, (h) to the best of the Requesting Party's knowledge, all of
       Landlord's obligations with respect to the installation of improvements
       to the Premises to prepare them for Tenant's use have been satisfied (or
       the extent to which they have not been satisfied), (i) that (if the
       Responding Party is Tenant) no actions, whether voluntary or otherwise,
       are pending against Tenant under any bankruptcy laws of the United States
       or any state thereof, and (j) such other matters reasonably requested by
       the Requesting Party.  Tenant and Landlord acknowledge that any statement
       delivered pursuant to this Article may be relied upon by any such party,
       and the Responding Party shall be liable for all loss, cost or expense
       resulting from or caused by any material misstatement contained in such
       estoppel certificate, or the failure to deliver the estoppel certificate.

12.16  REMEDYING DEFAULTS.  Landlord shall have the right, but shall not be
       required, to pay such sums or do any act which requires the expenditure
       of monies which may be necessary or appropriate by reason of the failure
       or neglect of Tenant to perform any of the provisions of this Lease, and
       in the event of the exercise of such right by Landlord, Tenant agrees to
       pay to Landlord forthwith upon demand all such sums, together with
       interest thereon at a rate equal to three percent (3%) over the so-called
       "Base Rate" in effect from time to time at the First National Bank of
       Boston, but in no event less than ten percent (10%) per annum, as an
       additional charge; provided, however, if such interest rate exceeds the
       highest interest rate then allowed under applicable law, such interest
       rate shall be reduced automatically to the then highest interest rate
       allowed under


                                       33

<PAGE>

       law. In addition to its other remedies, Landlord shall have the right
       without notice or demand to add to the amount of any payment of Base
       Rent, Tenant's Share of operating and Tax Expenses or any other payment
       required to be made by Tenant hereunder, and which is not paid on or
       before the date the same is due, a late charge in an amount equal to five
       percent (5%) of the delinquent amounts and, if such amount remains
       delinquent for more than thirty (30) days, Landlord shall have the right
       without notice or demand to collect interest from Tenant on such
       delinquent amount at a rate equal to three percent (3%) over the so-
       called "Base Rate" in effect from time to time at The First National Bank
       of Boston, but in no event less than ten percent (10%) per annum, to
       compensate Landlord for the loss of the use of the amount not paid and
       the administrative costs caused by the delinquency, Tenant hereby
       agreeing that Landlord's damage by virtue of such delinquencies would be
       difficult to compute and acknowledging that the amount stated herein
       represents a reasonable estimate thereof.

12.17  HOLDING OVER.  Any holding over by Tenant after the expiration of the
       term of this Lease shall be treated as a daily tenancy at sufferance at a
       rate equal to 1-1/2 times the Base Rent then in effect plus Tenant's
       Share of operating and Tax Expenses and other charges herein provided
       (prorated on a daily basis) and shall otherwise be on the terms and
       conditions set forth in this Lease as far as applicable.

12.18  SURRENDER OF PREMISES.  Upon the expiration or earlier termination of the
       Term of this Lease, Tenant shall peaceably quit and surrender to Landlord
       the Premises in neat and clean condition and in good order, condition and
       repair, together with all alterations, additions and improvements which
       may have been made or installed in, on or to the Premises prior to or
       during the Term of this Lease, excepting only ordinary wear and Use and
       damage by fire or other casualty for which, under other provisions of
       this Lease, Tenant has no responsibility of repair or restoration.
       Tenant shall remove all of Tenant's Removable Property and, to the extent
       specified by Landlord, all alterations, additions and improvements made
       by Tenant; and shall repair any damages to the Premises or the Building
       caused by such removal.  Any Tenant's Removable Property which shall
       remain in the Building or on the Premises after the expiration or
       termination of the Term of this Lease shall be deemed conclusively to
       have been abandoned, and either may be retained by Landlord as its
       property or may be disposed of in such manner as Landlord may see fit, at
       Tenant's sole cost and expense.

12.19  BROKERAGE.  Landlord and Tenant each mutually warrants and represents to
       the other that they have dealt with no broker in connection with the
       consummation of this Lease other than Broker.  Landlord and Tenant hereby
       each agree to indemnify, defend and hold the other harmless from any
       claim arising from the breach of such representation and warranty.

12.20  GOVERNING LAW.  This Lease shall be governed exclusively by the
       provisions hereof and by the laws of the Commonwealth of Massachusetts,
       as the same may from time to time exist.


                                  ARTICLE XIII

                           TENANT CANCELLATION OPTION

13.1   CANCELLATION OPTION.  Tenant shall have the right and option (the
       "Termination Option") to terminate this Lease at the end of the thirty-
       sixth (36th) month, the forty-second (42nd) month, the forty-eighth
       (48th) month, the fifty-fourth (54th) month, and the fifty-ninth (59th)
       month of the Term (the "Termination Dates").  Tenant shall exercise its
       Termination Option by giving written notice (the "Termination Notice") to
       Landlord of its desire to terminate the Lease at least two hundred
       seventy (270) days prior to the applicable Termination Date.  In
       conjunction with its Termination Notice, if Tenant terminates at the end
       of the thirty-sixth month, Tenant shall pay Landlord a Termination Fee of
       Thirty Five Thousand Dollars ($35,000.00) ; provided, however if Tenant
       elects to exercise its Termination Option at one of the later Termination
       Dates, the amount of the Termination Fee shall be reduced by One Thousand
       Four Hundred Fifty Eight and 33/100 Dollars ($1,458.33) per month for
       each month the Tenant occupies the Premises after the thirty-sixth month.
       Tenant's failure to pay the Termination Fee at the time the Termination
       Notice is given shall render the Termination Notice null and void and of
       no effect whatsoever, time being of the essence of this paragraph.

                              (Operating Expenses)


Operating Expenses shall include:

1.   All expenses reasonably incurred by Landlord or Landlord's agents which
     shall be directly related to employment of personnel, including amounts
     incurred for wages, salaries and other compensation for services, payroll,
     social security, unemployment and similar taxes, workmen's compensation
     insurance, disability benefits, pensions, hospitalization, retirement plans
     and group insurance, uniforms and working clothes and the cleaning thereof,
     and expenses imposed on Landlord or Landlord's agents pursuant to any
     collective bargaining agreement for the services of employees of Landlord
     or Landlord's agents in connection with the operation, repair, maintenance,
     cleaning, management and protection of the Property, and its mechanical
     systems including, without limitation, day and night Building supervisors,
     the Property manager, janitors, carpenters, engineers, mechanics,
     electricians and plumbers but excluding any expenses for any executive
     employees.

2.   The cost reasonably incurred by Landlord for services, materials and
     supplies furnished or used in the operation, repair, maintenance, cleaning,
     management and protection of the Property.

3.   The cost of replacements for tools and other similar equipment used in the
     repair, maintenance, cleaning and protection of the Property, provided that
     such costs shall be suitably prorated, over the generally accepted useful
     life of such tools.

4.   Reasonable expenses incurred by Landlord in any real estate tax abatement
     proceeding.

5.   Premiums incurred by Landlord for insurance against damage or loss to the
     Building from such hazards as shall from time to time be generally required
     by institutional mortgagees in the Boston area for similar properties,
     including, but not by way of limitation, insurance covering loss of rent
     attributable to any such hazards, and public liability insurance and
     premiums for fidelity bonds covering persons having custody or control over
     funds or other property of Landlord relating to the Property.

6.   If, during the Term of this Lease, Landlord shall make a capital
     expenditure which is necessary to meet the requirements of applicable laws,
     regulations or ordinances or which is designed to increase the operating
     efficiency of the Building (which for purposes hereof, shall mean that the
     aggregate cost savings


                                       40

<PAGE>

     related to such capital improvement can reasonably be expected to equal the
     amount of such capital expenditure (plus the interest factor hereinafter
     referred to) within the generally accepted useful life of such
     improvement), the total cost of which is not properly includable in
     Operating Expenses for the Operating Year in which it was made, there shall
     nevertheless be included in such operating Expenses for the Operating Year
     in which it was made and in operating Expenses for each succeeding
     operating Year the annual charge-off of such capital expenditure.  Annual
     charge-off shall be determined by dividing the original capital expenditure
     by the number of years of useful life of the improvement made with the
     capital expenditure, and adding thereto a reasonable interest factor
     (taking into account the rate then being charged by institutional lenders
     for loans to finance the item over its useful life) on the unamortized
     portion of the capital expenditure; and the useful life shall be determined
     reasonably by Landlord in accordance with generally accepted accounting
     principles and practices in effect at the time of making such expenditure.

7.   Costs incurred by Landlord for electricity, fuel, water and sewer use
     charges, and all other utilities supplied to the Property and fees for any
     public services rendered to the Property, except for those actually paid or
     reimbursed to Landlord by tenants of the Property.

8.   Betterment assessments provided the same are apportioned equally over the
     longest period permitted by law, and all sales and use taxes relating to
     any items includable in Operating Expenses.

9.   Notwithstanding the foregoing, Operating Expenses shall not include the
     following: (a) the cost of repairs or replacements (i) resulting from
     casualty losses or eminent domain takings (other than the amount of any
     deductible) or (ii) correcting defects in design or construction of the
     Building; (b) costs incurred due to violation by Landlord of the terms and
     conditions of any lease, (c) depreciation or amortization of the Building
     or any part thereof; (d) replacement or contingency reserves; (e) ground
     lease rents or payment of any debt or equity obligations; (f) legal and
     other professional fees relating to negotiations with tenants, leasing,
     financing or other services not related to the normal operation,
     maintenance, cleaning, repair and protection of the Property; (g) brokerage
     fees and commissions; (h) the cost of special services rendered to Building
     tenants which are directly chargeable to such tenants; (i) expenses for
     renovating tenant space or incurred for the sole benefit of a particular
     tenant; and (j) Tax service fees.  Operating Expenses shall be reduced by
     the amount of any proceeds, awards, payments, guarantees, credits or
     reimbursements which Landlord actually receives and which are applicable to
     Operating Expenses, less the cost reasonably incurred in recovering such
     amount.

                                    GUARANTY


     This GUARANTY is made as of the 14th day of April, 1994 by, Kaiser
Aerospace and Electronics Corporation, a Nevada corporation, having an address
of 950 Tower Lane, Suite 800, Foster City, California, 94404 (the "Guarantor"),
for the purpose of inducing Robert F. Tambone, Trustee of MAT Realty Trust u/d/t
dated June 4, 1986 and recorded with the Worcester County Registry of Deeds in
Book 9569, Page 286, having a principal place of business at c/o Atlantic Realty
and Development, Inc. . 24 New England Executive Park, Burlington, MA 01803 (the
"Landlord"), to enter into a Lease (the "Lease") with OKTAS (the "Tenant"), a
Massachusetts general partnership, for 8,733 square feet of space in the
premises known as and numbered 134 Flanders Road, Westborough, Massachusetts
(the "Leased Premises"), upon the terms and conditions set forth in the Lease
which is attached hereto as Exhibit "A".

     In consideration of the foregoing, each of the undersigned agrees:

     1.   GUARANTY.  Subject to the terms and conditions of this Guaranty, the
Guarantor unconditionally guarantees to the Landlord prompt and full payment and
performance when due of all of the present and future amounts due from Tenant
under the Lease.  All such amounts due are referred to in this Guaranty as the
"Obligations." The Guarantor's liability hereunder is direct and unconditional
and may be enforced after nonpayment or nonperformance by the Tenant of any of
the obligations without requiring Landlord to resort to any other person or
entity (including, without limitation, the Tenant) or any other right, remedy or
collateral.

     2.   RIGHTS OF LANDLORD.  The Guarantor authorizes the Landlord to alter at
any time, in accordance with the terms of Lease, any of the terms of the
Obligations, to take and to hold any security for the obligations and to accept
additional or substituted security, to subordinate, compromise or release any
security, to release the Tenant from its liability for all or any part of the
Obligations, to release the Guarantor hereunder or to substitute or add one or
more guarantors or endorsers hereunder, and to assign this Guaranty in whole or
in part.  Landlord may take any and all of the foregoing actions upon such terms
and conditions as Landlord may elect, without obtaining the consent of the
Guarantor and without affecting the liability of the Guarantor to Landlord.
Landlord shall give Guarantor notice as required under paragraph 12.11 of the
Lease.

     3.   JOINT, SEVERAL AND INDEPENDENT LIABILITY.  The obligations of the
Guarantor under this Guaranty are joint and several and independent of the
obligations of the Tenant.  Landlord may release or settle with the Tenant or
any other guarantor at any time without affecting the continuing liability of
the Guarantor.  Landlord may proceed against the Guarantor under this Guaranty
without first proceeding against the Tenant, against any other Guarantor or any
other person or any security held by Landlord and without pursuing any other
remedy.  Landlord's rights under this Guaranty will not be


                                       42

<PAGE>

altered or exhausted by any action by Landlord until all of the Obligations have
been paid, performed and satisfied in full.

     4.   WAIVER OF INDULGENCE.  The Guarantor waives notice of acceptance of
this Guaranty and all presentment, demand, protest, notice of protest and
notices of default or dishonor of any obligation guaranteed hereby and all other
suretyship defenses generally.  No extension of time or other indulgence or
release of liability or collateral granted by Landlord to the Tenant or to the
Guarantor will release or affect the obligations of the Guarantor hereunder and
no act, omission or delay on the part of Landlord in exercising any rights
hereunder or in taking any action to collect or enforce payment or performance
of any of the obligations shall be a waiver of any such right or release or
affect the Obligations.  This Guaranty shall not be impaired by any bankruptcy,
insolvency, arrangement, assignment for the benefit of creditors, reorganization
or other debtor relief proceedings under any federal or state law,    whether
now existing or hereafter enacted, with respect to Tenant, or if for any other
reason Tenant or any other guarantor has no legal obligation to discharge any of
the obligations.

     5.   SUBORDINATION OF RIGHTS.  The Guarantor covenants and agrees that any
indebtedness of the Tenant to the Guarantor, whether arising from payments made
by the Guarantor pursuant to this Guaranty or otherwise, is hereby subordinated
to the Obligations and that after any default under the Lease, the Guarantor
shall hold any funds received from Tenant in trust for Landlord to satisfy the
Obligations.  This subordination of the indebtedness and other Obligations shall
continue until all of the Obligations have been paid, performed and satisfied in
full.  Nothing in this Section shall prevent the Guarantor from enforcing and
collecting any obligation owed to the Guarantor by the Tenant prior to a default
under the Lease or after the Obligations have been paid, performed and satisfied
in full.

     6.   DEFAULT.  Landlord may declare the Guarantor in default under this
Guaranty if the Guarantor fails to perform any of its obligations under this
Guaranty or under any other guaranty given to Landlord in connection with the
Lease.

     7.   DELAY; CUMULATIVE REMEDIES.  No delay or failure by the Landlord to
exercise any right or remedy against the Tenant or the Guarantor will be
construed as a waiver of that right or remedy.  All remedies of Landlord against
the Tenant and the Guarantor are cumulative.

     8.   EXPENSES OF COLLECTION.  The Guarantor shall pay to Landlord on demand
any and all expenses paid or incurred by Landlord, including reasonable
attorneys' fees and disbursements, in connection with the collection or
enforcement of the obligations or this Guaranty.  Until paid to Landlord, such
sums will bear interest at the default rate set forth in the Lease.  Provided,
however, if a legal proceeding is initiated to either collect or enforce the
Obligations, or to challenge such collection or enforcement, the


                                       43

<PAGE>

prevailing party shall be entitled to reasonable attorneys' fees and expenses of
litigation or arbitration in addition to any other relief to which it may be
entitled.

     9.   ENTIRE AGREEMENT.  The whole of this Guaranty is set forth herein, and
there is no verbal or other written agreement, and no understanding or custom
affecting the terms hereof.  This Guaranty can be modified only be a written
instrument signed by the parties to be charged.

     10.  INTERPRETATION AND BINDING EFFECT.  If any provision of this Guaranty
shall be held to be prohibited or invalid under applicable law, such provision
shall be ineffective only to the extent of such prohibition or invalidity,
without invalidating the remainder of such provision or the remaining provisions
of this Guaranty.  This Guaranty shall be governed and construed pursuant to
laws of The Commonwealth of Massachusetts and shall take effect as a sealed
instrument and shall be binding upon and inure to the benefit of the respective
successors and assigns of the parties hereto.

                                  ARTICLE XIII

                                SECURITY DEPOSIT

     13.1 Tenant has deposited with Landlord the Security Deposit which shall be
held by Landlord as security for the faithful performance by Tenant of all the
terms, covenants and conditions of this Lease to be kept and performed by Tenant
and, except as hereinafter stated, not as an advance rental deposit or as a
measure of Landlord's damage in case of Tenant's Default.  If a Default of
Tenant occurs Landlord may use any part of the Security Deposit for the payment
of any Base Rent, Tenant's Proportionate Share of Operating and Tax Expenses, or
other sum owing to Landlord, or for the payment of any amount which Landlord may
spend or become obligated to spend by reason of a Default of Tenant or to
compensate Landlord for any other loss or damage which Landlord may suffer by
reason of a Default of Tenant.  If any portion is so used, Tenant shall within
five (5) days after written demand therefore, deposit with Landlord an amount
sufficient to restore the Security Deposit to its original


                                        2

<PAGE>

amount.  Tenant's failure to do so shall be a material breach of this Lease.
Landlord shall not be required to keep this Security Deposit separate from its
general funds, and Tenant shall not be entitled to interest on such deposit.  If
Tenant shall fully and faithfully perform every provision of this Lease to be
performed by it, the Security Deposit or any balance thereof shall be returned
to Tenant within 60 days after termination of this Lease unless Landlord shall
have reasonably determined that Tenant's obligations under this Lease have not
been fulfilled.  Within  60 days after Landlord's reasonable determination of
Tenant's obligations under this Lease, Landlord shall return the Security
Deposit to Tenant to the extent not used to fully discharge Tenant's obligations
under Lease.  Notwithstanding anything in the foregoing to the contrary, in the
event no Default exists as of or after the date two (2) months prior to the
expiration date of the Term, upon written request of Tenant an amount equal to
no more than two months of Base Rent due under this Lease may be applied by
Tenant from the Security Deposit towards Tenant's remaining Base Rent
obligations.

     10.  Except as otherwise expressly stated herein, the Additional Premises
shall be delivered to Tenant by Landlord in its "AS IS" condition on the
Effective Date and thereupon shall become part of the Premises.  Landlord shall
not be obligated to install any tenant improvements.  Any work done by Tenant in
the Additional Premises shall be done in full compliance with all applicable
laws and regulations, with Section 5.2 of the Lease, and with all other
applicable provisions of the Lease. "Substantial Completion of the Tenant
Improvements" shall be deemed to be the earlier of (a) Tenant's occupancy of the
Additional Premises for Tenant's business purposes; (b) issuance of a
Certificate of Occupancy for the Additional Premises by the Town of Westborough;
or (c) completion of the Tenant Improvements to the extent that the Additional
Premises are in an operating condition usable by Tenant for the Permitted Uses
except for minor items of work which can be completed after occupancy has been
taken by Tenant without causing material interference with Tenant's use of the
Premises for the Permitted Uses (i.e. so-called "punch list" items).

     11.  Landlord and Tenant agree that Tenant shall be obligated to pay, in
the manner specified in Section 8.2 of the Lease, a management fee of three (3%)
percent of Base Rent relative to the Premises and the Additional Premises.

     12.  Landlord agrees to expeditiously construct a shipping/receiving area
(the "Shipping Area") serving Tenant and other space on the ground floor of the
Building.  Such area shall include a bell and associated nameplate for each
tenant served by the Shipping Area, each of which bells to ring only in the area
of the specified tenant.  Tenant agrees to share on a pro rata basis with other
tenants authorized by the Landlord to utilize the Shipping Area all Operating
Expenses arising with respect to the Shipping/Receiving Area, including without
limitation, Electricity Expenses, cleaning, maintenance and any additional


                                        3

insurance expense directly attributable to such Shipping Area or the use
thereof, all payable at times and in the manner specified in Section 8.2(b) of
the Lease.

     Except as expressly set forth herein, the Lease shall remain unmodified and
in full force and effect.

                                STANDARD SUBLEASE

                   American Industrial Real Estate Association


1.   PARTIES.  This sublease, dated, for reference purposes only, January 13, 
1996, is made by and between Quintiles Pacific, Inc. (formerly known as SDCRA, 
Inc.) (herein called "Sublessor") and VISTA MEDICAL TECHNOLOGIES, INC. 
(herein called "Sublessee").

2.   PREMISES. Sublessor hereby subleases to Sublessee and Sublessee hereby 
subleases from Sublessor for the term, at the rental, and upon all of the 
conditions set forth herein, that certain real property situated in the 
County of SAN DIEGO State of California, commonly known as 5451 Avenida 
Encinas, Suites A, B, C, J & K, Carlsbad, CA 92008 and described as 
Approximately 6,500 rentable square feet.
Said real property, including the land and all improvements thereon, is
hereinafter called the "Premises".

3.   TERM.

     3.1  TERM. The term of this Sublease shall be for 33 1/2 months (the
"Commencement Date") commencing on February 15, 1996 and ending on November 30,
1998 unless sooner terminated pursuant to any provision hereof.

     3.2  DELAY IN COMMENCEMENT. Notwithstanding said commencement date, if for
any reason Sublessor cannot deliver possession of the Premises to Sublessee on
said date, Sublessor shall not be subject to any liability therefore, nor shall
such failure affect the validity of this Lease or the obligations of Sublessee
hereunder or extend the term hereof, but in such case Sublessee shall not be
obligated to pay rent until possession of the Premises is tendered to Sublessee;
provided, however, that if Sublessor shall not have delivered possession of the
Premises within sixty (60) days from said commencement date, Sublessee may, at
Sublessee's option, by notice in writing to Sublessor within ten (10) days
thereafter, cancel this Sublease, in which event the parties shall be discharged
from all obligations thereunder. If Sublessee occupies the Premises prior to
said commencement date, such occupancy shall be subject to all provisions
hereof, such occupancy shall not advance the termination date and Sublessee
shall pay rent for such period at the initial monthly rates set forth below.

4.   RENT. Sublessee shall pay to Sublessor as rent for the Premises equal
monthly payments of $6,171.00, in advance, on the 1st day of each month of the
term hereof. Sublessee shall pay Sublessor upon the execution hereof $6,171.00
as rent for  the first month's rent. Commencing February 15, 1997, rent shall
increase as shown in paragraph 13 hereof.
Rent for any period during the term hereof which is for less than one month
shall be a prorata portion of the monthly installment. Rent shall be payable in
lawful money of the United States to Sublessor at the address stated herein or
to such other persons or at such other places as Sublessor may designate in
writing.

5.   SECURITY DEPOSIT. Sublessee shall deposit with Sublessor upon execution
hereof $6,171.00 as security for Sublessee's faithful performance of Sublessee's
obligations hereunder, if Sublessee fails to pay rent or other charges due
hereunder, or otherwise defaults with respect to any provision of this Sublease,
Sublessor 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 Sublessor may become obligated by reason of Sublessee's default, or
to compensate Sublessor for any loss or damage which Sublessor may suffer
thereby. If Sublessor so uses or applies all or any portion of said deposit,
Sublessee shall within ten (10) days after written demand therefore deposit cash
with Sublessor in an amount sufficient to restore said deposit to the full
amount hereinabove stated and Sublessee's failure to do so shall be a material
breach of this Sublease. Sublessor shall not be required to keep said deposit
separate from its general accounts. If Sublessee performs all of Sublessee's
obligations hereunder, said deposit, or so much thereof as has not theretofore
been applied by Sublessor, shall be returned, without payment of Interest or
other Increment for its use to Sublessee (or at Sublessor's option, to the last
assignee, if any, of Sublessee's Interest hereunder) at the expiration of the
term hereof, and after Sublessee has vacated the Premises. No trust relationship
is created herein between Sublessor and Sublessee with respect to said Security
Deposit.

6.   USE.

     6.1  USE. The Premises shall be used and occupied only for general offices,
research and development of computer systems and like products and any other
legally permitted use with and for no other purpose

     6.2  COMPLIANCE WITH LAW. Sublessor's prior written consent, which shall 
not be unreasonably  withheld,

     *Except as provided in Section 20 hereof,

     (b)* Sublessee shall, at Sublessee's expense, comply promptly with all
applicable statutes, ordinances, rules, regulations, orders, restrictions of
record, and requirements in effect during the term or any part of the term
hereof regulating the use by Sublessee of the Premises. Sublessee shall not use
or permit the use of the Premises in any manner that will tend to create waste
or a nuisance or, if there shall be more than one tenant of the building
containing the Premises, which shall lend to disturb such other tenants.

6.3  CONDITION OF PREMISES.    Sublessee hereby accepts the Premises in their
condition existing as of the date of the execution hereof, subject to all
applicable zoning, municipal, county and state laws, ordinances, and regulations
governing and regulating the use of the Premises, and accepts this Sublease
subject thereto and to all matters disclosed thereby and by any exhibits
attached hereto Sublessee acknowledges that neither Sublessor nor Sublessor's
agents have made any representation or warranty as to the suitability of the
Premises for the conduct of Sublessee's business.

7.   MASTER lEASE

     7.1 Sublessor is the lessee of the Premises by virtue of a lease,
hereinafter referred to as the "Master Lease", a copy of which is attached
hereto marked Exhibit 1, dated July 2, 1992 wherein Ocean Point Tech Centre is
the lessor, hereinafter referred to as the "Master Lessor"

     7.2 This Sublease is and shall be at all times subject and subordinate to
the Master Lease.

     7.3 The terms, conditions and respective obligations of Sublessor and
Sublessee to each other under this Sublease shall be the terms and conditions of
the Master Lease except for those provisions of the Master Lease which are
directly contradicted by this Sublease in which event the terms of this Sublease
document shall control over the Master Lease. Therefore, for the purposes of
this Sublease, wherever in the Master Lease the word "Lessor" is used it shall
be deemed to mean the Sublessor herein and wherever in the Master Lease the word
"Lessee" is used it shall be deemed to mean the Sublessee herein.

     7.4 During the term of this Sublease and for all periods subsequent for 
obligations which have arisen prior to the termination of this Sublease. 
Sublessee does hereby expressly assume and agree to perform and comply with, 
for the benefit of Sublessor and Master Lessor, each and every obligation of 
Sublessor under the Master Lease EXCEPT for the following paragraphs which 
are excluded therefrom:1.12 (a), 3.01 December 23, 1992 Rent Schedule, 1.05 
(Lease Term), 1.07 (Tenant's Guarantor), 1.08 (Brokers), 1.09 (Commission 
Payable to Landlord's Brokers), 1.10 (Security Deposit) and Article 14 
(Brokers). Sublessee shall be entitled to all rights of the Tenant under the 
Master Lease, except as provided  herein.

are hereinafter referred to as the "Sublessee's Assumed Obligations". The
obligations that Sublessee has NOT assumed under paragraph 7.4 hereof are
hereinafter referred to as the "Sublessor's Remain Obligations".

     7.6 Sublessee shall hold Sublessor free and harmless of and from all
liability, judgments, costs, damages, claims or demands, including reasonable
attorneys fees, arising out of Sublessee's failure to comply with or perform
Sublessee's Assumed Obligations.

     7.7 Sublessor agrees to maintain the Master Lease during the entire term of
this Sublease, subject, however, to any earlier termination of the Master Lease
without the fault of the Sublessor, and to comply with or perform Sublessor's
Remaining Obligations and to hold Sublessee free and harmless of and from all
liability, judgments, costs, damages, claims or demands arising out of
Sublessor's failure to comply with or perform Sublessor's Remaining Obligations.

     7.8 Sublessor represents to Sublessee that the Master Lease is in full
force and effect and that no default exists on the part of any party to the
Master Lease.


8. ASSIGNMENT OF SUBLEASE AND DEFAULT.

     8.1 Sublessor hereby assigns and transfers to Master Lessor the Sublessor's
interest in this Sublease and all rentals and income arising therefrom, subject
however to terms of Paragraph 8.2 hereof.

     8.2 Master Lessor, by executing this document, agrees that until a default
shall occur in the performance of Sublessor's Obligations under the Master
Lease, that Sublessor may receive, collect and enjoy the rents accruing under
this Sublease. However, if Sublessor shall default in the performance of its
obligations to Master Lessor then Master Lessor may, at its option, receive and
collect, directly from Sublessee, all rent owning and to be owed under this
Sublease. Master Lessor shall not, by reason of this assignment of the Sublease
nor by reason of the collection of the rent from the Sublessee, be deemed liable
to Sublessee for any failure of the Sublessor to perform and comply with
Sublessor's Remaining Obligations.

     8.3 Sublessor hereby irrevocably authorizes and directs Sublessee, upon
receipt of any written notice from the Master Lessor stating that default exists
in the performance of Sublessor's obligations under the Master Lease, to pay to
Master Lessor the rents due and to become due under the Sublease. Sublessor
agrees that Sublessee shall have the right to rely upon any such statement and
request from Master Lessor, and that Sublessee shall pay such rents to Master
Lessor without any obligation or right to inquire as to whether such default
exists and notwithstanding and notice from or claim from Sublessor to the
contrary and Sublessor shall have no right or claim against Sublessee for any
such rents so paid by Sublessee.

     8.4 No changes or modifications shall be made to this Sublease without the
consent of Master Lessor.


9. CONSENT OF MASTER LESSOR.

     9.1 In the event that the Master Lease requires that Sublessor obtain the
consent of Master Lessor to any subletting by Sublessor then, this Sublease
shall not be effective unless, within 10 days of the date hereof, Master Lessor
signs this Sublease thereby giving its consent to this Subletting.

     9.2 In the event that the obligations of the Sublessor under the Master
Lease have been guaranteed by third parties then this Sublease, nor the Master
Lessor's consent, shall not be effective unless, within 10 days of the date
hereof, said guarantors sign this Sublease thereby giving guarantors consent to
this Sublease and the terms thereof.

     9.3 In the event that Master Lessor does give such consent then:

       (a) Such consent will not release Sublessor of its obligations or alter
the primary liability of Sublessor to pay the rent and perform and comply with
all of the obligations of Sublessor to be performed under the Master Lease.

       (b) The acceptance of rent by Master Lessor from Sublessee or any one
else liable under the Master Lease shall not be deemed a waiver by Master Lessor
of any provisions of the Master Lease.

       (c) The consent to this Sublease shall not constitute a consent to any
subsequent subletting or assignment.

       (d) In the event of any default of Sublessor under the Master Lease,
Master Lessor may proceed directly against Sublessor, any guarantors or any one
else liable under the Master Lease or this Sublease without first exhausting
Master Lessor's remedies against any other person or entity liable thereon to
Master Lessor.

       (e) Master Lessor may consent to subsequent sublettings and assignments
of the Master Lease or this Sublease or any amendments or modifications thereto
without notifying Sublessor nor any one else liable under the Master Lease and
without obtaining their consent and such action shall not relieve such persons
from liability.

       (f) In the event that Sublessor shall default in its obligations under
the Master Lease, then Master Lessor, at its option and without being obligated
to do so, may require Sublessee to attorn to Master Lessor in which event Master
Lessor shall undertake the obligations of Sublessor under this Sublease from the
time of the exercise of said option to termination of this Sublease but Master
Lessor shall not be liable for any prepaid rents nor any security deposit paid
by Sublessee, nor shall Master Lessor be liable for any other defaults of the
Sublessor under the Sublease.

     9.4 The signatures of the Master Lessor and any Guarantors of Sublessor at
the end of this document shall constitute their consent to the terms of this
Sublease.

     9.5 Master Lessor acknowledges that, to the best of Master Lessor's
knowledge, no default presently exists under the Master Lease of obligations to
be performed by Sublessor and that the Master Lease is in full force and effect.

     9.6 In the event that Sublessor defaults under its obligations to be
performed under the Master Lease by Sublessor, Master Lessor agrees to deliver
to Sublessee a copy of any such notice of default. Sublessee shall have the
right to cure any default of Sublessor described in any notice of default within
ten days after service of such notice of default on Sublessee. If such default
is cured by Sublessee then Sublessee shall have the right of reimbursement and
offset from and against Sublessor.

     10.1 Upon execution hereof by all parties, Sublessor shall pay to Voit
Commercial Brokerage & CB Commercial, a licensed real estate broker, (herein
called "Broker"), a fee as set forth in a separate agreement between Sublessor
and Broker, or in the event there is no separate agreement between Sublessor and
Broker, the sum of $14,505.12 for brokerage services rendered by Broker to
Sublessor in this transaction.

     10.2 Sublessor agrees that if Sublessee exercises any option or right of
first refusal granted by Sublessor herein, or any option or right substantially
similar thereto, either to extend the term of this Sublease, to renew this
Sublease, to purchase the Premises, or to lease or purchase adjacent property
which Sublessor may own or in which Sublessor has an interest, or if Broker is
the procuring cause of any lease, sublease, or sale pertaining to the Premises
or any adjacent property which Sublessor may own or in which Sublessor has an
interest, then as to any of said transactions Sublessor shall pay to Broker a
fee, in cash, in accordance with the schedule of Broker in effect at the time of
the execution of this Sublease. Notwithstanding the foregoing, Sublessor's
obligation under this Paragraph 10.2 is limited to a transaction in which
Sublessor is acting as a sublessor, lessor or seller.

     10.3 Master Lessor agrees, by its consent to this Sublease, that if
Sublessee shall exercise any option or right of first refusal granted to
Sublessee by Master Lessor in connection with this Sublease, or any option or
right substantially similar thereto, either to extend the Master Lease, to renew
the Master Lease, to purchase the Premises or any part thereof, or to lease or
purchase adjacent property which Master Lessor may own or in which Master Lessor
has an interest, or if Broker is the procuring cause of any other lease or sale
entered into between Sublessee and Master Lessor pertaining to the Premises, any
part thereof, or any adjacent property which Master Lessor owns or in which it
has an interest, then as to any of said transactions Master Lessor shall pay to
Broker a fee, in cash, in accordance with the schedule of Broker in effect at
the time of its consent to this Sublease.

     10.4 Any fee due from Sublessor or Master Lessor hereunder shall be due and
payable upon the exercise of any option to extend or renew, as to any extension
or renewal; upon the execution of any new lease, as to a new lease transaction
or the exercise of a right of first refusal to lease; or at the close of escrow,
as to the exercise of any option to purchase or other sale transaction.

     10.5 Any transferee of Sublessor's interest in this Sublease, or of Master
Lessor's interest in the Master Lease, by accepting an assignment thereof, shall
be deemed to have assumed the respective obligations of Sublessor or Master
Lessor under this Paragraph 10. Broker shall be deemed to be a third-party
beneficiary of this paragraph 10.


11. ATTORNEY'S FEES. If any party or the Broker named herein brings an action to
enforce the terms hereof or to declare rights hereunder, the prevailing party in
any such action, on trial and appeal, shall be entitled to his reasonable
attorney's fees to be paid by the losing party as fixed by the Court. The

to Section 7.3 of this Sublease: (a) Section 5.05, Indemnity of the Lease, as
modified by Section 5.05(a) making all of Section 5.05 reciprocal and (b)
Section 12.01, Legal Proceedings, as modified by Section 12.01(a)  making

                                1995 STOCK OPTION PLAN


                                     ARTICLE ONE

                                  GENERAL PROVISIONS


    I.   PURPOSE OF THE PLAN

         This 1995 Stock Option Plan is intended to promote the interests of
Vista Medical Technologies, Inc., a California corporation, by providing
eligible persons with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in the service of the Corporation.

         Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

   II.   ADMINISTRATION OF THE PLAN

         A.   The Plan shall be administered by the Board.  However, any or all
administrative functions otherwise exercisable by the Board may be delegated to
the Committee.  Members of the Committee shall serve for such period of time as
the Board may determine and shall be subject to removal by the Board at any
time.  The Board may also at any time terminate the functions of the Committee
and reassume all powers and authority previously delegated to the Committee.

         B.   The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options as it may deem necessary or advisable.  Decisions of the
Plan Administrator shall be final and binding on all parties who have an
interest in the Plan or any option or shares issued thereunder.

  III.   ELIGIBILITY

         A.   The persons eligible to receive option grants under the Plan are
as follows:

                (i)     Employees,

<PAGE>

               (ii)     non-employee members of the Board or the
    non-employee members of the board of directors of any Parent or
    Subsidiary, and

              (iii)     consultants who provide services to the
    Corporation (or any Parent or Subsidiary).

         B.   The Plan Administrator shall have full authority to determine
which eligible persons are to receive option grants under the Plan, the time or
times when such option grants are to be made, the number of shares to be covered
by each such grant, the status of the granted option as either an Incentive
Option or a Non-Statutory Option, the time or times at which each option is to
become exercisable, the vesting schedule (if any) applicable to the option
shares and the maximum term for which the option is to remain outstanding.

  IV.    STOCK SUBJECT TO THE PLAN

         A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock.  The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed 896,208
shares.

         B.   Shares of Common Stock subject to outstanding options shall be
available for subsequent issuance under the Plan to the extent (i) the options
expire or terminate for any reason prior to exercise in full or (ii) the options
are cancelled in accordance with the cancellation-regrant provisions of Article
Two.  All shares issued under the Plan, whether or not those shares are
subsequently repurchased by the Corporation pursuant to its repurchase rights
under the Plan, shall reduce on a share-for-share basis the number of shares of
Common Stock available for subsequent issuance under the Plan.

         C.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and/or class of securities issuable
under the Plan and (ii) the number and/or class of securities and the exercise
price per share in effect under each outstanding option in order to prevent the
dilution or enlargement of benefits thereunder.  The adjustments determined by
the Plan Administrator shall be final, binding and conclusive.  In no event
shall any such adjustments be made in connection with the conversion of one or
more outstanding shares of the Corporation's preferred stock into shares of
Common Stock.


                                          2.

<PAGE>

                                     ARTICLE TWO

                                 OPTION GRANT PROGRAM


    I.   OPTION TERMS

         Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; PROVIDED, however, that each such document
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

         A.   EXERCISE PRICE.

              1.   The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                (i)     The exercise price per share shall not be less than
    eighty-five percent (85%) of the Fair Market Value per share of Common
    Stock on the option grant date.

               (ii)     If the person to whom the option is granted is a 10%
    Shareholder, then the exercise price per share shall not be less than one
    hundred ten percent (110%) of the Fair Market Value per share of Common
    Stock on the option grant date.

              2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Three and the documents evidencing the option, be payable in cash or
check made payable to the Corporation.  Should the Common Stock be registered
under Section 12(g) of the 1934 Act at the time the option is exercised, then
the exercise price may also be paid as follows:

                (i)     in shares of Common Stock held for the requisite
    period necessary to avoid a charge to the Corporation's earnings for
    financial reporting purposes and valued at Fair Market Value on the
    Exercise Date, or

               (ii)     to the extent the option is exercised for vested
    shares, through a special sale and remittance procedure pursuant to
    which the Optionee shall concurrently provide irrevocable written
    instructions (a) to a Corporation-designated brokerage firm to effect
    the immediate sale of the purchased shares and remit to the
    Corporation, out of the sale proceeds available on the settlement
    date, sufficient funds to cover the aggregate exercise price payable
    for the purchased shares plus all


                                          3.

<PAGE>

    applicable Federal, state and local income and employment taxes required to
    be withheld by the Corporation by reason of such exercise and (b) to the
    Corporation to deliver the certificates for the purchased shares directly
    to such brokerage firm in order to complete the sale.

         Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

         B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option grant.  However, no option shall have a term in excess of
ten (10) years measured from the option grant date.

         C.   EFFECT OF TERMINATION OF SERVICE.  The following provisions shall
govern the exercise of any options held by the Optionee at the time of cessation
of Service or death:

                (i)     Should the Optionee cease to remain in Service for
    any reason other than Disability or death, then the Optionee shall
    have a period of three (3) months following the date of such cessation
    of Service during which to exercise each outstanding option held by
    such Optionee.

               (ii)     Should such Service terminate by reason of
    Disability, then the Optionee shall have a period of six (6) months
    following the date of such cessation of Service during which to
    exercise each outstanding option held by such Optionee.   However,
    should such Disability be deemed to constitute Permanent Disability,
    then the period during which each outstanding option held by the
    Optionee is to remain exercisable shall be extended by an additional
    six (6) months so that the exercise period shall be the twelve
    (12)-month period following the date of the Optionee's cessation of
    Service by reason of such Permanent Disability.

              (iii)     Should the Optionee die while holding one or more
    outstanding options, then the personal representative of the
    Optionee's estate or the person or persons to whom the option is
    transferred pursuant to the Optionee's will or in accordance with the
    laws of descent and distribution shall have a period of twelve (12)
    months following the date of the Optionee's death during which to
    exercise each such option.

               (iv)     Under no circumstances, however, shall any such
    option be exercisable after the specified expiration of the option
    term.

                                          4.

<PAGE>

                (v)     During the applicable post-Service exercise
    period, the option may not be exercised in the aggregate for more than
    the number of vested shares for which the option is exercisable on the
    date of the Optionee's cessation of Service.  Upon the expiration of
    the applicable exercise period or (if earlier) upon the expiration of
    the option term, the option shall terminate and cease to be
    outstanding for any vested shares for which the option has not been
    exercised.  However, the option shall, immediately upon the Optionee's
    cessation of Service, terminate and cease to be outstanding to the
    extent it is not exercisable for vested shares on the date of such
    cessation of Service.

         D.   SHAREHOLDER RIGHTS.  The holder of an option shall have no
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

         E.   UNVESTED SHARES.  The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock under the Plan.  Should the Optionee cease Service while holding such
unvested shares, the Corporation shall have the right to repurchase, at the
exercise price paid per share, all or (at the discretion of the Corporation and
with the consent of the Optionee) any of those unvested shares.  The terms upon
which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right.  The Plan Administrator may not
impose a vesting schedule upon any option grant or any shares of Common Stock
subject to the option which is more restrictive than twenty percent (20%) per
year vesting, with the initial vesting to occur one (1) year after the option
grant date.  However, this minimum vesting requirement shall not be applicable
with respect to any option granted to a Highly-Compensated Person.

         F.   FIRST REFUSAL RIGHTS.  Until such time as the Common Stock is
first registered under Section 12(g) of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan.  Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

         G.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
Optionee, the option shall be exercisable only by the Optionee and shall not be
assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death.  However, a Non-Statutory Option
may be assigned in whole or in part during Optionee's lifetime in accordance
with the terms of a Qualified Domestic Relations Order.  The assigned portion
may only be exercised by the person or persons who acquire a proprietary
interest in the option pursuant to such Qualified Domestic Relations Order.  The
terms applicable to the assigned portion shall be the same as those in effect
for the


                                          5.

option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.

         H.   WITHHOLDING.  The Corporation's obligation to deliver shares of
Common Stock upon the exercise of any options granted under the Plan shall be
subject to the satisfaction of all applicable Federal, state and local income
and employment tax withholding requirements.

   II.   INCENTIVE OPTIONS

         The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options.  Options which
are specifically designated as Non-Statutory Options shall NOT be subject to the
terms specified in this Section II.

         A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.


         B.   EXERCISE PRICE.  The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.

         C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one (1) calendar year
shall not exceed the sum of One Hundred Thousand Dollars ($100,000).  To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

         D.   10% SHAREHOLDER.  If any Employee to whom an Incentive Option is
granted is a 10% Shareholder, then the option term shall not exceed five (5)
years measured from the option grant date.

  III.   CORPORATE TRANSACTION

         A.   In the event of any Corporate Transaction, each outstanding
option shall terminate and cease to be outstanding, except to the extent assumed
by the successor corporation (or parent thereof) in connection with such
Corporate Transaction.  In addition, all outstanding repurchase rights under the
Plan shall terminate automatically in the event of any Corporate Transaction,
except to the extent the repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction.


                                          6.

<PAGE>

         B.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in the consummation of such Corporate Transaction,
had the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, PROVIDED the aggregate exercise price payable for such
securities shall remain the same.

         C.   The grant of options under the Plan shall in no way affect the
right of the Corporation to adjust, reclassify, reorganize or otherwise change
its capital or business structure or to merge, consolidate, dissolve, liquidate
or sell or transfer all or any part of its business or assets.

   IV.   CANCELLATION AND REGRANT OF OPTIONS

         The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                    ARTICLE THREE

                                    MISCELLANEOUS


    I.   FINANCING

         The Plan Administrator may permit any Optionee to pay the option
exercise price by delivering a promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  Promissory notes may be authorized with or without
security or collateral.  However, any promissory notes delivered by a consultant
must be secured by property other than the purchased shares of Common Stock.  In
all events, the maximum credit available to each Optionee may not exceed the SUM
of (i) the aggregate option exercise price payable for the purchased shares plus
(ii) any Federal, state and local income and employment tax liability incurred
by the Optionee in connection with the option exercise.


                                          7.

<PAGE>

   II.   ADDITIONAL AUTHORITY

         A.   The Plan Administrator shall have the discretion, exercisable
either at the time an option is granted or at any time while the option remains
outstanding:

                (i)     to extend the period of time for which the option
    is to remain exercisable following the Optionee's cessation of Service
    or death from the limited period otherwise in effect for that option
    to such greater period of time as the Plan Administrator shall deem
    appropriate; PROVIDED, that in no event shall such option be
    exercisable after the specified expiration of the option term, and/or

               (ii)     to permit the option to be exercised, during the
    applicable post-Service exercise period, not only with respect to the
    number of vested shares of Common Stock for which such option is
    exercisable at the time of the Optionee's cessation of Service or
    death but also with respect to one or more additional installments in
    which the Optionee would have vested under the option had the Optionee
    continued in Service.

  III.   EFFECTIVE DATE AND TERM OF THE PLAN

         A.   The Plan shall become effective when adopted by the Board, but no
option granted under the Plan may be exercised until the Plan is approved by the
Corporation's shareholders.  If such shareholder approval is not obtained within
twelve (12) months after the date of the Board's adoption of the Plan, then all
options previously granted under the Plan shall terminate and cease to be
outstanding, and no further options shall be granted.  Subject to such
limitation, the Plan Administrator may grant options under the Plan at any time
after the effective date of the Plan and before the date fixed herein for
termination of the Plan.

         B.   The Plan shall terminate upon the EARLIEST of (i) the expiration
of the ten (10)-year period measured from the date the Plan is adopted by the
Board, (ii) the date on which all shares available for issuance under the Plan
shall have been issued or (iii) the termination of all outstanding options in
connection with a Corporate Transaction.  Upon such Plan termination, all
options and unvested stock issuances outstanding under the Plan shall continue
to have full force and effect in accordance with the provisions of the documents
evidencing such options or issuances.

   IV.   AMENDMENT OF THE PLAN

         A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall, without the consent of the Optionees, adversely affect
their rights and obligations under their outstanding options.  In addition, the
Board shall not, without the


                                          8.

<PAGE>

approval of the Corporation's shareholders, (i) increase the maximum number of
shares issuable under the Plan, except for permissible adjustments in the event
of certain changes in the Corporation's capitalization, (ii) materially modify
the eligibility requirements for Plan participation or (iii) materially increase
the benefits accruing to Plan participants.

         B.   Options may be granted under the Plan to purchase shares of
Common Stock in excess of the number of shares then available for issuance under
the Plan, provided any such options actually granted may not be exercised until
there is obtained shareholder approval of an amendment sufficiently increasing
the number of shares of Common Stock available for issuance under the Plan.  If
such shareholder  approval is not obtained within twelve (12) months after the
date the excess grants are first made, then any options granted on the basis of
such excess shares shall terminate and cease to be outstanding.

    V.   USE OF PROCEEDS

         Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

   VI.   REGULATORY APPROVALS

         The implementation of the Plan, the granting of any option hereunder
and the issuance of any shares of Common Stock upon the exercise of any option
shall be subject to the Corporation's procurement of all approvals and permits
required by regulatory authorities having jurisdiction over the Plan, the
options granted under it and the shares of Common Stock issued pursuant to it.

  VII.   NO EMPLOYMENT OR SERVICE RIGHTS

         Nothing in the Plan shall confer upon the Optionee any right to
continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any Parent or
Subsidiary employing or retaining Optionee) or of the Optionee, which rights are
hereby expressly reserved by each, to terminate the Optionee's Service at any
time for any reason, with or without cause.

 VIII.   FINANCIAL REPORTS

         The Corporation shall deliver a balance sheet and an income statement
at least annually to each individual holding an outstanding option under the
Plan, unless such individual is a key Employee whose duties in connection with
the Corporation (or any Parent or Subsidiary) assure such individual access to
equivalent information.

                        VISTA MEDICAL TECHNOLOGIES, INC.
                             STOCK OPTION AGREEMENT


RECITALS

     A.   The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or the board
of directors of any Parent or Subsidiary and consultants who provide services to
the Corporation (or any Parent or Subsidiary).

     B.   Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

     C.   All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

          NOW, THEREFORE, it is hereby agreed as follows:

          1.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice.  The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

          2.   OPTION TERM.  This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5, 6 or 17.

          3.   LIMITED TRANSFERABILITY.  This option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.  However, if this option is designated a
Non-Statutory Option in the Grant Notice, then this option may also be assigned
in whole or in part during Optionee's lifetime in accordance with the terms of a
Qualified Domestic Relations Order.  The assigned position shall be exercisable
only by the person or persons who acquire a proprietary interest in the option
pursuant to such Qualified Domestic Relations Order.  The terms applicable to
the assigned portion shall be the same as those in effect for this option
immediately prior to such assignment and shall be set forth in such documents
issued to the assignee as the Plan Administrator may deem appropriate.

          4.   DATES OF EXERCISE.  This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice.  As
the option becomes

<PAGE>

exercisable for such installments, those installments shall accumulate and the
option shall remain exercisable for the accumulated installments until the
Expiration Date or sooner termination of the option term under Paragraph 5, 6 or
17.

          5.   CESSATION OF SERVICE.  The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable:

               (a)  Should Optionee cease to remain in Service for any reason
(other than death or Disability) while this option is outstanding, then Optionee
shall have a period of three (3) months (commencing with the date of such
cessation of Service) during which to exercise this option, but in no event
shall this option be exercisable at any time after the Expiration Date.

               (b)  Should Optionee die while this option is outstanding, then
the personal representative of Optionee's estate or the person or persons to
whom the option is transferred pursuant to Optionee's will or in accordance with
the laws of descent and distribution shall have the right to exercise this
option.  Such right shall lapse and this option shall cease to be outstanding
upon the EARLIER of (i) the expiration of the twelve (12)- month period measured
from the date of Optionee's death or (ii) the Expiration Date.

               (c)  Should Optionee cease Service by reason of Disability while
this option is outstanding, then Optionee shall have a period of six (6) months
(commencing with the date of such cessation of Service) during which to exercise
this option.  However, should such Disability be deemed to constitute Permanent
Disability, then the period during which this option is to remain exercisable
shall be extended by an additional six (6) months so that the exercise period
shall be the twelve (12)-month period following the date of Optionee's cessation
of Service by reason of such Permanent Disability.  In no event shall this
option be exercisable at any time after the Expiration Date.

          NOTE:  Exercise of this option on a date later than three
          (3) months following cessation of Service due to Disability
          will result in loss of favorable Incentive Option treatment,
          UNLESS such Disability constitutes Permanent Disability.  In
          the event that Incentive Option treatment is not available,
          this option will be taxed as a Non-Statutory Option upon
          exercise.

               (d)  During the limited period of post-Service exercisability,
this option may not be exercised in the aggregate for more than the number of
vested Option Shares for which the option is exercisable at the time of
Optionee's cessation of Service.  Upon the expiration of such limited exercise
period or (if earlier) upon the Expiration Date, this option shall terminate and
cease to be outstanding for any vested Option Shares for which the option has
not been exercised.  To the extent Optionee is not vested in the

<PAGE>

Option Shares at the time of Optionee's cessation of Service, this option shall
immediately terminate and cease to be outstanding with respect to those shares.

          6.   SPECIAL TERMINATION OF OPTION.

               (a)  In the event of a Corporate Transaction, this option shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation or parent thereof in connection with such Corporate
Transaction.

               (b)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, PROVIDED the aggregate Exercise Price shall remain the same.

               (c)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

          7.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder.

          8.   SHAREHOLDER RIGHTS.  The holder of this option shall not have any
shareholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

          9.   MANNER OF EXERCISING OPTION.

               (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                      (i)     Execute and deliver to the Corporation a
     Purchase Agreement for the Option Shares for which the option is
     exercised.

                                       3.

<PAGE>


                     (ii)     Pay the aggregate Exercise Price for the
     purchased shares in one or more of the following forms:

                         (A)  cash or check made payable to the
          Corporation; or

                         (B)  a promissory note payable to the Corporation,
          but only to the extent authorized by the Plan Administrator in
          accordance with Paragraph 14.

               Should the Common Stock be registered under Section 12(g) of
          the 1934 Act at the time the option is exercised, then the
          Exercise Price may also be paid as follows:

                         (C)  in shares of Common Stock held by Optionee
          (or any other person or persons exercising the option) for the
          requisite period necessary to avoid a charge to the Corporation's
          earnings for financial reporting purposes and valued at Fair
          Market Value on the Exercise Date; or

                         (D)  to the extent the option is exercised for
          vested Option Shares, through a special sale and remittance
          procedure pursuant to which Optionee (or any other person or
          persons exercising the option) shall concurrently provide
          irrevocable written instructions (a) to a Corporation-designated
          brokerage firm to effect the immediate sale of the purchased
          shares and remit to the Corporation, out of the sale proceeds
          available on the settlement date, sufficient funds to cover the
          aggregate Exercise Price payable for the purchased shares plus
          all applicable Federal, state and local income and employment
          taxes required to be withheld by the Corporation by reason of
          such exercise and (b) to the Corporation to deliver the
          certificates for the purchased shares directly to such brokerage
          firm in order to complete the sale.

               Except to the extent the sale and remittance procedure is
          utilized in connection with the option exercise, payment of the
          Exercise Price must accompany the Purchase Agreement delivered to
          the Corporation in connection with the option exercise.

                    (iii)     Furnish to the Corporation appropriate
     documentation that the person or persons exercising the option (if
     other than Optionee) have the right to exercise this option.

                    (iv)      Execute and deliver to the Corporation such
     written representations as may be requested by the Corporation in
     order

                                       4.

<PAGE>

     for it to comply with the applicable requirements of Federal and state
     securities laws.

                     (v)      Make appropriate arrangements with the
     Corporation (or Parent or Subsidiary employing or retaining Optionee)
     for the satisfaction of all Federal, state and local income and
     employment tax withholding requirements applicable to the option
     exercise.

               (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.


               (c)  In no event may this option be exercised for any fractional
shares.

          10.  REPURCHASE RIGHTS.  ALL OPTION SHARES ACQUIRED UPON THE EXERCISE
OF THIS OPTION SHALL BE SUBJECT TO CERTAIN RIGHTS OF THE CORPORATION AND ITS
ASSIGNS TO REPURCHASE THOSE SHARES IN ACCORDANCE WITH THE TERMS SPECIFIED IN THE
PURCHASE AGREEMENT.

          11.  COMPLIANCE WITH LAWS AND REGULATIONS.

               (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

               (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.

          12.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the
benefit of, and be binding upon, the Corporation and its successors and assigns
and Optionee, Optionee's assigns and the legal representatives, heirs and
legatees of Optionee's estate.

indicated below Optionee's signature line on the Grant Notice.  All notices
shall be deemed effective upon personal delivery or upon deposit in the U.S.
mail, postage prepaid and properly addressed to the party to be notified.

          14.  FINANCING.  The Plan Administrator may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a promissory note.
The terms of any such promissory note (including the interest rate, the
requirements for collateral and the terms of repayment) shall be established by
the Plan Administrator in its sole discretion.(1)

          15.  CONSTRUCTION.  This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan.  All decisions of the Plan Administrator with
respect to any question or issue arising under the Plan or this Agreement shall
be conclusive and binding on all persons having an interest in this option.

          16.  GOVERNING LAW.  The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of California
without resort to that State's conflict-of-laws rules.

          17.  SHAREHOLDER APPROVAL.

               (a)  The grant of this option is subject to approval of the Plan
by the Corporation's shareholders within twelve (12) months after the adoption
of the Plan by the Board.  NOTWITHSTANDING ANY PROVISION OF THIS AGREEMENT TO
THE CONTRARY, THIS OPTION MAY NOT BE EXERCISED IN WHOLE OR IN PART UNTIL SUCH
SHAREHOLDER APPROVAL IS OBTAINED.  In the event that such shareholder approval
is not obtained, then this option shall terminate in its entirety and Optionee
shall have no further rights to acquire any Option Shares hereunder.

               (b)  If the Option Shares covered by this Agreement exceed, as of
the Grant Date, the number of shares of Common Stock which may without
shareholder approval be issued under the Plan, then this option shall be void
with respect to such excess shares, unless shareholder approval of an amendment
sufficiently increasing the number of shares of Common Stock issuable under the
Plan is obtained in accordance with the provisions of the Plan.

          18.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION.  In the event
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:

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

(1)   Authorization of payment of the Exercise Price by a promissory note may,
under currently proposed Treasury Regulations, result in the loss of incentive
stock option treatment under the Federal tax laws.

                                       6.

<PAGE>

               (a)  This option shall cease to qualify for favorable tax
treatment as an Incentive Option if (and to the extent) this option is exercised
for one or more Option Shares: (i) more than three (3) months after the date
Optionee ceases to be an Employee for any reason other than death or Permanent
Disability or (ii) more than twelve (12) months after the date Optionee ceases
to be an Employee by reason of Permanent Disability.

               (b)  This option shall not become exercisable in the calendar
year in which granted if (and to the extent) the aggregate Fair Market Value
(determined at the Grant Date) of the Common Stock for which this option would
otherwise first become exercisable in such calendar year would, when added to
the aggregate value (determined as of the respective date or dates of grant) of
the Common Stock and any other securities for which one or more other Incentive
Options granted to Optionee prior to the Grant Date (whether under the Plan or
any other option plan of the Corporation or any Parent or Subsidiary) first
become exercisable during the same calendar year, exceed One Hundred Thousand
Dollars ($100,000) in the aggregate.  To the extent the exercisability of this
option is deferred by reason of the foregoing limitation, the deferred portion
shall become exercisable in the first calendar year or years thereafter in which
the One Hundred Thousand Dollar ($100,000) limitation of this Paragraph 18(b)
would not be contravened, but such deferral shall in all events end immediately
prior to the effective date of a Corporate Transaction in which this option is
not to be assumed, whereupon the option shall become immediately exercisable as
a Non-Statutory Option for the deferred portion of the Option Shares.

               (c)  Should Optionee hold, in addition to this option, one or
more other options to purchase Common Stock which become exercisable for the
first time in the same calendar year as this option, then the foregoing
limitations on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

                        VISTA MEDICAL TECHNOLOGIES, INC.
                            STOCK PURCHASE AGREEMENT


          AGREEMENT made as of this ___ day of ________ 19____, by and among
Vista Medical Technologies, Inc., a California corporation, ___________________,
Optionee under the Corporation's 1995 Stock Option Plan, and __________________,
Optionee's spouse.

          All capitalized terms in this Agreement shall have the meaning
assigned to them in this Agreement or in the attached Appendix.

     AC.  EXERCISE OF OPTION

          1.   EXERCISE.  Optionee hereby purchases  ____________ shares of
Common Stock (the "Purchased Shares") pursuant to that certain option (the
"Option") granted Optionee on ____________________, 199__ (the "Grant Date") to
purchase up to _______________ shares of Common Stock under the Plan at the
exercise price of $______ per share (the "Exercise Price").

accordance with the provisions of the Option Agreement and shall deliver

<PAGE>

     AD.  SECURITIES LAW COMPLIANCE

          1.   RESTRICTED SECURITIES.  The Purchased Shares have not been
registered under the 1933 Act and are being issued to Optionee in reliance upon
the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan.  Optionee hereby
confirms that Optionee has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available.  Accordingly,
Optionee hereby acknowledges that Optionee is prepared to hold the Purchased
Shares for an indefinite period and that Optionee is aware that SEC Rule 144
issued under the 1933 Act which exempts certain resales of unrestricted
securities is not presently available to exempt the resale of the Purchased
Shares from the registration requirements of the 1933 Act.

          2.   RESTRICTIONS ON DISPOSITION OF PURCHASED SHARES.  Optionee shall
make no disposition of the Purchased Shares (other than a Permitted Transfer)
unless and until there is compliance with all of the following requirements:

               (i)  Optionee shall have provided the Corporation with a
     written summary of the terms and conditions of the proposed
     disposition.

               (ii) Optionee shall have complied with all requirements of
     this Agreement applicable to the disposition of the Purchased Shares.

              (iii)  Optionee shall have provided the Corporation with
     written assurances, in form and substance satisfactory to the
     Corporation, that (a) the proposed disposition does not require
     registration of the Purchased Shares under the 1933 Act or (b) all
     appropriate action necessary for compliance with the registration
     requirements of the 1933 Act or any exemption from registration
     available under the 1933 Act (including Rule 144) has been taken.

               (iv)  Optionee shall have provided the Corporation with
     written assurances, in form and substance satisfactory to the
     Corporation, that the proposed disposition will not result in the
     contravention of any transfer restrictions applicable to the Purchased
     Shares pursuant to the provisions of the Rules of the California
     Corporations Commissioner identified in Paragraph B.4.

          The Corporation shall NOT be required (i) to transfer on its books any
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement OR (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.

                                       2.

<PAGE>

          3.   RESTRICTIVE LEGENDS.  The stock certificates for the Purchased
Shares shall be endorsed with one or more of the following restrictive legends:

               (i)  "The shares represented by this certificate have not
     been registered under the Securities Act of 1933.  The shares may not
     be sold or offered for sale in the absence of (a) an effective
     registration statement for the shares under such Act, (b) a 'no
     action' letter of the Securities and Exchange Commission with respect
     to such sale or offer or (c) satisfactory assurances to the
     Corporation that registration under such Act is not required with
     respect to such sale or offer."

               (ii) "It is unlawful to consummate a sale or transfer of
     this security, or any interest therein, or to receive any
     consideration therefor, without the prior written consent of the
     Commissioner of Corporations of the State of California, except as
     permitted in the Commissioner's Rules."

              (iii) "The shares represented by this certificate are subject
     to certain repurchase rights and rights of first refusal granted to
     the Corporation and accordingly may not be sold, assigned,
     transferred, encumbered, or in any manner disposed of except in
     conformity with the terms of a written agreement dated ____________,
     199__ between the Corporation and the registered holder of the shares
     (or the predecessor in interest to the shares).  A copy of such
     agreement is maintained at the Corporation's principal corporate
     offices."

          4.   RECEIPT OF COMMISSIONER RULES.  Optionee hereby acknowledges
receipt of a copy of Section 260.141.11 of the Rules of the California
Corporations Commissioner, a copy of which is attached as Exhibit II to this
Agreement.

     AE.  TRANSFER RESTRICTIONS

          1.   RESTRICTION ON TRANSFER.  Except for any Permitted Transfer,
Optionee shall not transfer, assign, encumber or otherwise dispose of any of the
Purchased Shares which are subject to the Repurchase Right.  In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right, the Market Stand-Off or the Special Purchase Right.

          2.   TRANSFEREE OBLIGATIONS.  Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Optionee.

                                       3.

          3.   MARKET STAND-OFF.

               (a)  In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters.  Such restriction (the "Market Stand-Off")
shall be in effect for such period of time from and after the effective date of
the final prospectus for the offering as may be requested by the Corporation or
such underwriters.  In no event, however, shall such period exceed one hundred
eighty (180) days and the Market Stand-Off shall in all events terminate two (2)
years after the effective date of the Corporation's initial public offering.

               (b)  Owner shall be subject to the Market Stand-Off PROVIDED AND
ONLY IF the officers and directors of the Corporation are also subject to
similar restrictions.

               (c)  Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

               (d)  In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

     AF.  REPURCHASE RIGHT

          1.   GRANT.  The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Optionee ceases for any reason to remain in Service or (if
later) during the sixty (60)-day period following the execution date of this
Agreement, to repurchase at the Exercise Price all or (at the discretion of the
Corporation and with the consent of Optionee) any portion of the Purchased
Shares in which Optionee is not, at the time of his or her cessation of Service,
vested in accordance with the Vesting Schedule set forth in the Notice of Grant
or as otherwise provided in paragraph D.6 (such shares to be hereinafter
referred to as the "Unvested Shares").

          2.   EXERCISE OF THE REPURCHASE RIGHT.  The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period.  The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice.  The certificates

                                       4.

<PAGE>

representing the Unvested Shares to be repurchased shall be delivered to the
Corporation prior to the close of business on the date specified for the
repurchase.  Concurrently with the receipt of such stock certificates, the
Corporation shall pay to Owner, in cash or cash equivalents (including the
cancellation of any purchase-money indebtedness), an amount equal to the
Exercise Price previously paid for the Unvested Shares which are to be
repurchased from Owner.

          3.   TERMINATION OF THE REPURCHASE RIGHT.  The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2.  In addition, the Repurchase Right shall
terminate and cease to be exercisable with respect to any and all Purchased
Shares in which Optionee vests in accordance with the Vesting Schedule set forth
in the Notice of Grant or as otherwise provided in Paragraph D.6.  All Purchased
Shares as to which the Repurchase Right lapses shall, however, remain subject to
(i) the First Refusal Right, (ii) the Market Stand-Off and (iii) the Special
Purchase Right.

          4.   AGGREGATE VESTING LIMITATION.  If the Option is exercised in more
than one increment so that Optionee is a party to one or more other Stock
Purchase Agreements (the "Prior Purchase Agreements") which are executed prior
to the date of this Agreement, then the total number of Purchased Shares as to
which Optionee shall be deemed to have a fully-vested interest under this
Agreement and all Prior Purchase Agreements shall not exceed in the aggregate
the number of Purchased Shares in which Optionee would otherwise at the time be
vested, in accordance with the Vesting Schedule, had all the Purchased Shares
(including those acquired under the Prior Purchase Agreements) been acquired
exclusively under this Agreement.

          5.   RECAPITALIZATION.  Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right, but only
to the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments to reflect such distribution shall be made to the number
and/or class of Purchased Shares subject to this Agreement and to the price per
share to be paid upon the exercise of the Repurchase Right in order to reflect
the effect of any such Recapitalization upon the Corporation's capital
structure; PROVIDED, however, that the aggregate purchase price shall remain the
same.

          6.   CORPORATE TRANSACTION.

               (a)  Immediately prior to the consummation of any Corporate
Transaction, the Repurchase Right shall automatically lapse in its entirety,
except to the extent the Repurchase Right is to be assigned to the successor
corporation (or parent thereof) in connection with the Corporate Transaction.

                                       5.

<PAGE>

               (b)  To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to the new capital
stock or other property (including any cash payment) received in exchange for
the Purchased Shares in consummation of the Corporate Transaction, but only to
the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments shall be made to the price per share payable upon
exercise of the Repurchase Right to reflect the effect of the Corporate
Transaction upon the Corporation's capital structure; PROVIDED, however, that
the aggregate purchase price shall remain the same.

     AG.  RIGHT OF FIRST REFUSAL

          1.   GRANT.  The Corporation is hereby granted the right of first
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Optionee has vested in accordance with
the Vesting Schedule.  For purposes of this Article E, the term "transfer" shall
include any sale, assignment, pledge, encumbrance or other disposition of the
Purchased Shares intended to be made by Owner, but shall not include any
Permitted Transfer.

          2.   NOTICE OF INTENDED DISPOSITION.  In the event any Owner of
Purchased Shares in which Optionee has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

          3.   EXERCISE OF THE FIRST REFUSAL RIGHT.  The Corporation shall, for
a period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents.  Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period.  If such right is exercised with respect
to all the Target Shares, then the Corporation shall effect the repurchase of
such shares, including payment of the purchase price, not more than five (5)
business days after delivery of the Exercise Notice; and at such time the
certificates representing the Target Shares shall be delivered to the
Corporation.

          Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property.  If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an

                                       6.

<PAGE>

appraiser of recognized standing selected by Owner and the Corporation or, if
they cannot agree on an appraiser within twenty (20) days after the
Corporation's receipt of the Disposition Notice, each shall select an appraiser
of recognized standing and the two (2) appraisers shall designate a third
appraiser of recognized standing, whose appraisal shall be determinative of such
value.  The cost of such appraisal shall be shared equally by Owner and the
Corporation.  The closing shall then be held on the LATER of (i) the fifth (5th)
business day following delivery of the Exercise Notice or (ii) the fifth (5th)
business day after such valuation shall have been made.

          4.   NON-EXERCISE OF THE FIRST REFUSAL RIGHT.  In the event the
Exercise Notice is not given to Owner prior to the expiration of the twenty-five
(25)-day exercise period, Owner shall have a period of thirty (30) days
thereafter in which to sell or otherwise dispose of the Target Shares to the
third-party offeror identified in the Disposition Notice upon terms (including
the purchase price) no more favorable to such third-party offeror than those
specified in the Disposition Notice; PROVIDED, however, that any such sale or
disposition must not be effected in contravention of the provisions of Articles
B and C.  The third-party offeror shall acquire the Target Shares free and clear
of the Repurchase Right and the First Refusal Right, but the acquired shares
shall remain subject to the provisions of Article B and Paragraph C.3.  In the
event Owner does not effect such sale or disposition of the Target Shares within
the specified thirty (30)-day period, the First Refusal Right shall continue to
be applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses.

          5.   PARTIAL EXERCISE OF THE FIRST REFUSAL RIGHT.  In the event the
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:

               (i)  sale or other disposition of all the Target Shares to
     the third-party offeror identified in the Disposition Notice, but in
     full compliance with the requirements of Paragraph E.4, as if the
     Corporation did not exercise the First Refusal Right; or

               (ii) sale to the Corporation of the portion of the Target
     Shares which the Corporation has elected to purchase, such sale to be
     effected in substantial conformity with the provisions of Paragraph
     E.3.  The First Refusal Right shall continue to be applicable to any
     subsequent disposition of the remaining Target Shares until such right
     lapses.

          Failure of Owner to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.

                                       7.

<PAGE>

          6.   RECAPITALIZATION/REORGANIZATION.

               (a)  Any new, substituted or additional securities or other
property which is by reason of any Recapitalization distributed with respect to
the Purchased Shares shall be immediately subject to the First Refusal Right,
but only to the extent the Purchased Shares are at the time covered by such
right.

               (b)  In the event of a Reorganization, the First Refusal Right
shall remain in full force and effect and shall apply to the new capital stock
or other property received in exchange for the Purchased Shares in consummation
of the Reorganization, but only to the extent the Purchased Shares are at the
time covered by such right.

          7.   LAPSE.  The First Refusal Right shall lapse upon the EARLIEST to
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination is made by
the Board that a public market exists for the outstanding shares of Common Stock
or (iii) a firm commitment underwritten public offering, pursuant to an
effective registration statement under the 1933 Act, covering the offer and sale
of the Common Stock in the aggregate amount of at least ten million dollars
($10,000,000).  However, the Market Stand-Off shall continue to remain in full
force and effect following the lapse of the First Refusal Right.

     AH.  MARITAL DISSOLUTION OR LEGAL SEPARATION

          1.   GRANT.  In connection with the dissolution of Optionee's marriage
or the legal separation of Optionee and Optionee's spouse, the Corporation shall
have the right (the "Special Purchase Right") to purchase from Optionee's
spouse, in accordance with the provisions of Paragraph F.3, all or any portion
of the Purchased Shares which would otherwise be awarded to such spouse in
settlement of any community property or other marital property rights such
spouse may have in such shares.

          2.   NOTICE OF DECREE OR AGREEMENT.  Optionee shall promptly provide
the Corporation with written notice (the "Dissolution Notice") of (i) the entry
of any judicial decree or order resolving the property rights of Optionee and
Optionee's spouse in connection with their marital dissolution or legal
separation or (ii) the execution of any contract or agreement relating to the
distribution or division of such property rights. The Dissolution Notice shall
be accompanied by a copy of the actual decree or order of dissolution or
contract or agreement between Optionee and Optionee's spouse which provides for
the award to the spouse of one or more Purchased Shares in settlement of any
community property or other marital property rights such spouse may have in such
shares.

          3.   EXERCISE OF THE SPECIAL PURCHASE RIGHT.  The Special Purchase
Right shall be exercisable by delivery of written notice (the "Purchase Notice")
to Optionee and Optionee's spouse within thirty (30) days after the
Corporation's receipt of the Dissolution Notice.  The Purchase Notice shall
indicate the number of shares to be purchased by the

                                       8.

<PAGE>

Corporation, the date such purchase is to be effected (such date to be not less
than five (5) business days, nor more than ten (10) business days, after the
date of the Purchase Notice) and the Fair Market Value to be paid for such
Purchased Shares.  Optionee (or Optionee's spouse, to the extent such spouse has
physical possession of the Purchased Shares) shall, prior to the close of
business on the date specified for the purchase, deliver to the Corporation the
certificates representing the shares to be purchased.  The Corporation shall,
concurrently with the receipt of the stock certificates, pay to Optionee's
spouse (in cash or cash equivalents) an amount equal to the Fair Market Value
specified for such shares in the Purchase Notice.

          If Optionee's spouse does not agree with the Fair Market Value
specified for the shares in the Purchase Notice, then the spouse shall promptly
notify the Corporation in writing of such disagreement and the fair market value
of such shares shall thereupon be determined by an appraiser of recognized
standing selected by the Corporation and the spouse.  If they cannot agree on an
appraiser within twenty (20) days after the date of the Purchase Notice, each
shall select an appraiser of recognized standing, and the two (2) appraisers
shall designate a third appraiser of recognized standing whose appraisal shall
be determinative of such value.  The cost of the appraisal shall be shared
equally by the Corporation and Optionee's spouse.  The closing shall then be
held on the fifth (5th) business day following the completion of such appraisal;
PROVIDED, however, that if the appraised value is more than twenty-five percent
(25%) greater than the Fair Market Value specified for the shares in the
Purchase Notice, the Corporation shall have the right, exercisable prior to the
expiration of such five (5) business-day period, to rescind the exercise of the
Special Purchase Right and thereby revoke its election to purchase the shares
awarded to the spouse.  In the event the Corporation so revokes its election,
the Corporation shall bear the entire cost of the appraisal.

          4.   LAPSE.  The Special Purchase Right shall lapse upon the EARLIER
to occur of (i) the lapse of the First Refusal Right or (ii) the expiration of
the exercise period specified in Paragraph F.3, to the extent the Special
Purchase Right is not timely exercised in accordance with such paragraph.

     AI.  ESCROW

          1.   DEPOSIT.  Upon issuance, the certificates for the Purchased
Shares which are subject to the Repurchase Right shall be deposited in escrow
with the Corporation to be held in accordance with the provisions of this
Article G.  Each deposited certificate shall be accompanied by a duly-executed
Assignment Separate from Certificate in the form of Exhibit I.  The deposited
certificates, together with any other assets or securities from time to time
deposited with the Corporation pursuant to the requirements of this Agreement,
shall remain in escrow until such time or times as the certificates (or other
assets and securities) are to be released or otherwise surrendered for
cancellation in accordance with Paragraph G.3.  Upon delivery of the
certificates (or other assets and securities) to the

                                       9.

<PAGE>

Corporation, Owner shall be issued a receipt acknowledging the number of
Purchased Shares (or other assets and securities) delivered in escrow.

          2.   RECAPITALIZATION/REORGANIZATION.   Any new, substituted or
additional securities or other property which is by reason of any
Recapitalization or Reorganization distributed with respect to the Purchased
Shares shall be immediately delivered to the Corporation to be held in escrow
under this Article G, but only to the extent the Purchased Shares are at the
time subject to the escrow requirements hereunder.  However, all regular cash
dividends on the Purchased Shares (or other securities at the time held in
escrow) shall be paid directly to Owner and shall not be held in escrow.

          3.   RELEASE/SURRENDER.  The Purchased Shares, together with any other
assets or securities held in escrow hereunder, shall be subject to the following
terms relating to their release from escrow or their surrender to the
Corporation for repurchase and cancellation:

               (i)  Should the Corporation elect to exercise the Repurchase
     Right with respect to any Unvested Shares, then the escrowed
     certificates for those Unvested Shares (together with any other assets
     or securities attributable thereto) shall be surrendered to the
     Corporation concurrently with the payment to Owner of an amount equal
     to the aggregate Exercise Price for such Unvested Shares, and Owner
     shall cease to have any further rights or claims with respect to such
     Unvested Shares (or other assets or securities attributable thereto).

               (ii) Should the Corporation elect to exercise the First
     Refusal Right with respect to any Target Shares held at the time in
     escrow hereunder, then the escrowed certificates for those Target
     Shares (together with any other assets or securities attributable
     thereto) shall be surrendered to the Corporation concurrently with the
     payment of the Paragraph E.3 purchase price for such Target Shares to
     Owner, and Owner shall cease to have any further rights or claims with
     respect to such Target Shares (or other assets or securities
     attributable thereto).

               (iii)     Should the Corporation elect NOT to exercise the
     Repurchase Right with respect to any Unvested Shares or the First
     Refusal Right with respect to any Target Shares held at the time in
     escrow hereunder, then the escrowed certificates for those shares
     (together with any other assets or securities attributable thereto)
     shall be released to Owner.

               (iv) As the Purchased Shares (or any other assets or
     securities attributable thereto) vest in accordance with the Vesting
     Schedule, the certificates for those vested shares (as well as all
     other vested assets and

                                       10.

<PAGE>

     securities) shall be released from escrow upon Owner's request, but not
     more frequently than once every six (6) months.

               (v)  All Purchased Shares which vest (and any other vested
     assets and securities attributable thereto) shall be released within
     thirty (30) days after the EARLIER to occur of (a) Optionee's
     cessation of Service or (b) the lapse of the First Refusal Right.

               (vi) All Purchased Shares (or other assets or securities)
     released from escrow shall nevertheless remain subject to (a) the
     First Refusal Right, to the extent such right has not otherwise
     lapsed, (b) the Market Stand-Off, until such restriction terminates,
     and (c) the Special Purchase Right, to the extent such right has not
     otherwise lapsed.

     AJ.  SPECIAL TAX ELECTION

          The acquisition of the Purchased Shares may result in adverse tax
consequences which may be mitigated by filing an election under Code Section
83(b).  Such election must be filed within thirty (30) days after the date of
this Agreement.  A description of the tax consequences applicable to the
acquisition of the Purchased Shares and the form for making the Code Section
83(b) election are set forth in Exhibit III.  OPTIONEE SHOULD CONSULT WITH HIS
OR HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING THE PURCHASED
SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE SECTION 83(b)
ELECTION.  OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY, AND
NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN
IF OPTIONEE REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING
ON HIS OR HER BEHALF.

     AK.  GENERAL PROVISIONS

          1.   ASSIGNMENT.  The Corporation may assign the Repurchase Right, the
First Refusal Right and/or the Special Purchase Right to any person or entity
selected by the Board, including (without limitation) one or more shareholders
of the Corporation.

          If the assignee of the Repurchase Right is other than (i) a wholly
owned subsidiary of the Corporation or (ii) the parent corporation owning one
hundred percent (100%) of the Corporation's outstanding capital stock, then such
assignee must make a cash payment to the Corporation, upon the assignment of the
Repurchase Right, in an amount equal to the excess (if any) of (i) the Fair
Market Value of the Purchased Shares at the time subject to the assigned
Repurchase Right over (ii) the aggregate repurchase price payable for the
Purchased Shares.

                                       11.

<PAGE>

          2.   NO EMPLOYMENT OR SERVICE CONTRACT.  Nothing in this Agreement or
in the Plan shall confer upon Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Parent or Subsidiary employing or
retaining Optionee) or of Optionee, which rights are hereby expressly reserved
by each, to terminate Optionee's Service at any time for any reason, with or
without cause.

          3.   NOTICES.  Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

          4.   NO WAIVER.  The failure of the Corporation in any instance to
exercise the Repurchase Right, the First Refusal Right or the Special Purchase
Right shall not constitute a waiver of any other repurchase rights and/or rights
of first refusal that may subsequently arise under the provisions of this
Agreement or any other agreement between the Corporation and Optionee or
Optionee's spouse.  No waiver of any breach or condition of this Agreement shall
be deemed to be a waiver of any other or subsequent breach or condition, whether
of like or different nature.

          5.   CANCELLATION OF SHARES.  If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement).  Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

     AL.  MISCELLANEOUS PROVISIONS

          1.   OPTIONEE UNDERTAKING.  Optionee hereby agrees to take whatever
additional action and execute whatever additional documents the Corporation may
deem necessary or advisable in order to carry out or effect one or more of the
obligations or restrictions imposed on either Optionee or the Purchased Shares
pursuant to the provisions of this Agreement.

          2.   AGREEMENT IS ENTIRE CONTRACT.  This Agreement constitutes the
entire contract between the parties hereto with regard to the subject matter
hereof.  This Agreement is made pursuant to the provisions of the Plan and shall

construed in accordance with, the laws of the State of California without resort
to that State's conflict-of-laws rules.

          4.   COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

          5.   SUCCESSORS AND ASSIGNS.  The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Optionee, Optionee's assigns and the legal representatives,
heirs and legatees of Optionee's estate, whether or not any such person shall
have become a party to this Agreement and have agreed in writing to join herein
and be bound by the terms hereof.

          6.   POWER OF ATTORNEY.  Optionee's spouse hereby appoints Optionee
his or her true and lawful attorney in fact, for him or her and in his or her
name, place and stead, and for his or her use and benefit, to agree to any
amendment or modification of this Agreement and to execute such further
instruments and take such further actions as may reasonably be necessary to

do and perform every act necessary and proper to be done in the exercise of any
of the foregoing powers as fully as he or she might or could do if personally
present, with full power of substitution and revocation, hereby ratifying and
confirming all that Optionee shall lawfully do and cause to be done by virtue of
this power of attorney.

                                       13.

               260.141.11 Restriction on Transfer.  (a) The issuer of any
security upon which a restriction on transfer has been imposed pursuant to
Sections 260.102.6, 260.141.10 or 260.534 shall cause a copy of this section to

               (b)  It is unlawful for the holder of any such security to
consummate a sale or transfer of such security, or any interest therein, without
the prior written consent of the Commissioner (until this condition is removed
pursuant to Section 260.141.12 of these rules), except:

               (7)  by or through a broker-dealer licensed under the Code
(either acting as such or as a finder) to a resident of a foreign state,
territory or country who is neither domiciled in this state to the knowledge of
the broker-dealer, nor actually present in this state if the sale of such
securities is not in violation of any securities law of the foreign state,
territory or country concerned;

               (8)  to a broker-dealer licensed under the Code in a principal
transaction, or as an underwriter or member of an underwriting syndicate or
selling group;

lien given by the purchaser to the seller upon a sale of the security for which
the Commissioner's written consent is obtained or under this rule not required;

                                      II-1.

                                   EXHIBIT III

                      FEDERAL INCOME TAX CONSEQUENCES AND
                           SECTION 83(B) TAX ELECTION

     I.        FEDERAL INCOME TAX CONSEQUENCES AND SECTION 83(b) ELECTION FOR
EXERCISE OF NON-STATUTORY OPTION.  If the Purchased Shares are acquired pursuant
to the exercise of a Non-Statutory Option, as specified in the Grant Notice,
then under Code Section 83, the excess of the Fair Market Value of the Purchased
Shares on the date any forfeiture restrictions applicable to such shares lapse
over the Exercise Price paid for such shares will be reportable as ordinary
income on the lapse date.  For this purpose, the term "forfeiture restrictions"
includes the right of the Corporation to repurchase the Purchased Shares
pursuant to the Repurchase Right.  However, Optionee may elect under Code
Section 83(b) to be taxed at the time the Purchased Shares are acquired, rather
than when and as such Purchased Shares cease to be subject to such forfeiture
restrictions.  Such election must be filed with the Internal Revenue Service
within thirty (30) days after the date of the Agreement.  Even if the Fair
Market Value of the Purchased Shares on the date of the Agreement equals the
Exercise Price paid (and thus no tax is payable), the election must be made to
avoid adverse tax consequences in the future.  The form for making this election
is attached as part of this exhibit.  FAILURE TO MAKE THIS FILING WITHIN THE
APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY
INCOME BY OPTIONEE AS THE FORFEITURE RESTRICTIONS LAPSE.

     II.       FEDERAL INCOME TAX CONSEQUENCES AND CONDITIONAL SECTION 83(b)
ELECTION FOR EXERCISE OF INCENTIVE OPTION.  If the Purchased Shares are acquired
pursuant to the exercise of an Incentive Option, as specified in the Grant
Notice, then the following tax principles shall be applicable to the Purchased
Shares:

                    (i)  For regular tax purposes, no taxable income will
     be recognized at the time the Option is exercised.

                    (ii) The excess of (a) the Fair Market Value of the
     Purchased Shares on the date the Option is exercised or (if later) on
     the date any forfeiture restrictions applicable to the Purchased
     Shares lapse over (b) the Exercise Price paid for the Purchased Shares
     will be includible in Optionee's taxable income for alternative
     minimum tax purposes.

                   (iii) If Optionee makes a disqualifying disposition
     of the Purchased Shares, then Optionee will recognize ordinary income
     in the year of such disposition equal in amount to the excess of (a)
     the Fair Market Value of the Purchased Shares on the date the Option
     is exercised or (if later) on the date any forfeiture restrictions
     applicable to the Purchased Shares lapse over (b) the Exercise Price
     paid for the Purchased Shares.  Any additional gain recognized upon
     the disqualifying disposition will be either short-term or long-term
     capital gain depending upon the period for which the Purchased Shares
     are held prior to the disposition.

                                     III-1.

<PAGE>

                    (iv) For purposes of the foregoing, the term
     "forfeiture restrictions" will include the right of the Corporation to
     repurchase the Purchased Shares pursuant to the Repurchase Right.  The
     term "disqualifying disposition" means any sale or other disposition(2)
     of the Purchased Shares within two (2) years after the Grant Date or within
     one (1) year after the exercise date of the Option.

                    (v)  In the absence of final Treasury Regulations
     relating to Incentive Options, it is not certain whether Optionee may,
     in connection with the exercise of the Option for any Purchased Shares
     at the time subject to forfeiture restrictions, file a protective
     election under Code Section 83(b) which would limit (a) Optionee's
     alternative minimum taxable income upon exercise and (b) Optionee's
     ordinary income upon a disqualifying disposition to the excess of the
     Fair Market Value of the Purchased Shares on the date the Option is
     exercised over the Exercise Price paid for the Purchased Shares.
     Accordingly, such election if properly filed will only be allowed to
     the extent the final Treasury Regulations permit such a protective
     election.  Page 2 of the attached form for making the election should
     be filed with any election made in connection with the exercise of an
     Incentive Option.

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


(2)  Generally, a disposition of shares purchased under an Incentive Option
includes any transfer of legal title, including a transfer by sale, exchange or
gift, but does not include a transfer to the Optionee's spouse, a transfer into
joint ownership with right of survivorship if Optionee remains one of the joint
owners, a pledge, a transfer by bequest or inheritance or certain tax free
exchanges permitted under the Code.

THIS ELECTION MUST BE FILED WITH THE INTERNAL REVENUE SERVICE CENTER WITH WHICH
TAXPAYER FILES HIS OR HER FEDERAL INCOME TAX RETURNS AND MUST BE MADE WITHIN
THIRTY (30) DAYS AFTER THE EXECUTION DATE OF THE STOCK PURCHASE AGREEMENT.  THIS
FILING SHOULD BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED.
OPTIONEE MUST RETAIN TWO (2) COPIES OF THE COMPLETED FORM FOR FILING WITH HIS OR
HER FEDERAL AND STATE TAX RETURNS FOR THE CURRENT TAX YEAR AND AN ADDITIONAL
COPY FOR HIS OR HER RECORDS.

The property described in the above Section 83(b) election is comprised of
shares of common stock acquired pursuant to the exercise of an incentive stock
option under Section 422 of the Internal Revenue Code (the "Code").
Accordingly, it is the intent of the Taxpayer to utilize this election to
achieve the following tax results:

               1.   The purpose of this election is to have the alternative
minimum taxable income attributable to the purchased shares measured by the
amount by which the fair market value of such shares at the time of their
transfer to the Taxpayer exceeds the purchase price paid for the shares.  In the
absence of this election, such alternative minimum taxable income would be
measured by the spread between the fair market value of the purchased shares and
the purchase price which exists on the various lapse dates in effect for the
forfeiture restrictions applicable to such shares.  The election is to be
effective to the full extent permitted under the Code.

               2.   Section 421(a)(1) of the Code expressly excludes from income
any excess of the fair market value of the purchased shares over the amount paid
for such shares.  Accordingly, this election is also intended to be effective in
the event there is a "disqualifying disposition" of the shares, within the
meaning of Section 421(b) of the Code, which would otherwise render the
provisions of Section 83(a) of the Code applicable at that time.  Consequently,
the Taxpayer hereby elects to have the amount of disqualifying disposition
income measured by the excess of the fair market value of the purchased shares
on the date of transfer to the Taxpayer over the amount paid for such shares.
Since Section 421(a) presently applies to the shares which are the subject of
this Section 83(b) election, no taxable income is actually recognized for
regular tax purposes at this time, and no income taxes are payable, by the
Taxpayer as a result of this election.


THIS PAGE 2 IS TO BE ATTACHED TO ANY SECTION 83(b) ELECTION FILED IN CONNECTION
WITH THE EXERCISE OF AN INCENTIVE STOCK OPTION UNDER THE FEDERAL TAX LAWS.

     I.        PURPOSE OF THE PLAN

               This 1995 Stock Option Plan is intended to promote the interests
of Vista Medical Technologies, Inc., a California corporation, by providing
eligible persons with the opportunity to acquire a proprietary interest, or
otherwise increase their proprietary interest, in the Corporation as an
incentive for them to remain in the service of the Corporation.

               Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.       ADMINISTRATION OF THE PLAN

               A.   The Plan shall be administered by the Board.  However, any
or all administrative functions otherwise exercisable by the Board may be
delegated to the Committee.  Members of the Committee shall serve for such
period of time as the Board may determine and shall be subject to removal by the
Board at any time.  The Board may also at any time terminate the functions of
the Committee and reassume all powers and authority previously delegated to the
Committee.

               B.   The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and regulations
as it may deem appropriate for proper administration of the Plan and to make
such determinations under, and issue such interpretations of, the Plan and any
outstanding options as it may deem necessary or advisable.  Decisions of the
Plan Administrator shall be final and binding on all parties who have an
interest in the Plan or any option or shares issued thereunder.

     III.      ELIGIBILITY

               A.   The persons eligible to receive option grants under the Plan
are as follows:

                      (i)     Employees,

<PAGE>

                     (ii)     non-employee members of the Board or the non-
     employee members of the board of directors of any Parent or
     Subsidiary, and

                    (iii)     consultants who provide services to the
     Corporation (or any Parent or Subsidiary).

               B.   The Plan Administrator shall have full authority to
determine which eligible persons are to receive option grants under the Plan,
the time or times when such option grants are to be made, the number of shares
to be covered by each such grant, the status of the granted option as either an
Incentive Option or a Non-Statutory Option, the time or times at which each
option is to become exercisable, the vesting schedule (if any) applicable to the
option shares and the maximum term for which the option is to remain
outstanding.

     IV.       STOCK SUBJECT TO THE PLAN

               A.   The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock.  The maximum number of
shares of Common Stock which may be issued over the term of the Plan shall not
exceed 896,208 shares.

               B.   Shares of Common Stock subject to outstanding options shall
be available for subsequent issuance under the Plan to the extent (i) the
options expire or terminate for any reason prior to exercise in full or (ii) the
options are cancelled in accordance with the cancellation-regrant provisions of
Article Two.  All shares issued under the Plan, whether or not those shares are
subsequently repurchased by the Corporation pursuant to its repurchase rights
under the Plan, shall reduce on a share-for-share basis the number of shares of
Common Stock available for subsequent issuance under the Plan.

               C.   Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option in order to
prevent the dilution or enlargement of benefits thereunder.  The adjustments
determined by the Plan Administrator shall be final, binding and conclusive.  In
no event shall any such adjustments be made in connection with the conversion of
one or more outstanding shares of the Corporation's preferred stock into shares
of Common Stock.

                                       2.

                              OPTION GRANT PROGRAM


     I.        OPTION TERMS

               Each option shall be evidenced by one or more documents in the
form approved by the Plan Administrator; PROVIDED, however, that each such
document shall comply with the terms specified below.  Each document evidencing
an Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

               A.   EXERCISE PRICE.

                    1.   The exercise price per share shall be fixed by the Plan
Administrator in accordance with the following provisions:

                      (i)     The exercise price per share shall not be less
     than eighty-five percent (85%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                     (ii)     If the person to whom the option is granted is a
     10% Shareholder, then the exercise price per share shall not be less than
     one hundred ten percent (110%) of the Fair Market Value per share of Common
     Stock on the option grant date.

                    2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Three and the documents evidencing the option, be payable in cash or
check made payable to the Corporation.  Should the Common Stock be registered
under Section 12(g) of the 1934 Act at the time the option is exercised, then
the exercise price may also be paid as follows:

                      (i)     in shares of Common Stock held for the
     requisite period necessary to avoid a charge to the Corporation's
     earnings for financial reporting purposes and valued at Fair Market
     Value on the Exercise Date, or

                     (ii)     to the extent the option is exercised for
     vested shares, through a special sale and remittance procedure
     pursuant to which the Optionee shall concurrently provide irrevocable
     written instructions (a) to a Corporation-designated brokerage firm to
     effect the immediate sale of the purchased shares and remit to the
     Corporation, out of the sale proceeds available on the settlement
     date, sufficient funds to cover the aggregate exercise price payable
     for the purchased shares plus all

                                       3.

<PAGE>

     applicable Federal, state and local income and employment taxes required to
     be withheld by the Corporation by reason of such exercise and (b) to the
     Corporation to deliver the certificates for the purchased shares directly
     to such brokerage firm in order to complete the sale.

               Except to the extent such sale and remittance procedure is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

               B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option grant.  However, no option shall have a term in
excess of ten (10) years measured from the option grant date.

               C.   EFFECT OF TERMINATION OF SERVICE.  The following provisions
shall govern the exercise of any options held by the Optionee at the time of
cessation of Service or death:

                      (i)     Should the Optionee cease to remain in
     Service for any reason other than Disability or death, then the
     Optionee shall have a period of three (3) months following the date of
     such cessation of Service during which to exercise each outstanding
     option held by such Optionee.

                     (ii)     Should such Service terminate by reason of
     Disability, then the Optionee shall have a period of six (6) months
     following the date of such cessation of Service during which to
     exercise each outstanding option held by such Optionee.   However,
     should such Disability be deemed to constitute Permanent Disability,
     then the period during which each outstanding option held by the
     Optionee is to remain exercisable shall be extended by an additional
     six (6) months so that the exercise period shall be the twelve (12)-
     month period following the date of the Optionee's cessation of Service
     by reason of such Permanent Disability.

                    (iii)     Should the Optionee die while holding one or
     more outstanding options, then the personal representative of the
     Optionee's estate or the person or persons to whom the option is
     transferred pursuant to the Optionee's will or in accordance with the
     laws of descent and distribution shall have a period of twelve (12)
     months following the date of the Optionee's death during which to
     exercise each such option.

                     (iv)     Under no circumstances, however, shall any
     such option be exercisable after the specified expiration of the
     option term.

                                       4.

<PAGE>

                      (v)     During the applicable post-Service exercise
     period, the option may not be exercised in the aggregate for more than
     the number of vested shares for which the option is exercisable on the
     date of the Optionee's cessation of Service.  Upon the expiration of
     the applicable exercise period or (if earlier) upon the expiration of
     the option term, the option shall terminate and cease to be
     outstanding for any vested shares for which the option has not been
     exercised.  However, the option shall, immediately upon the Optionee's
     cessation of Service, terminate and cease to be outstanding to the
     extent it is not exercisable for vested shares on the date of such
     cessation of Service.

               D.   SHAREHOLDER RIGHTS.  The holder of an option shall have no
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

               E.   UNVESTED SHARES.  The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock under the Plan.  Should the Optionee cease Service while holding such
unvested shares, the Corporation shall have the right to repurchase, at the
exercise price paid per share, all or (at the discretion of the Corporation and
with the consent of the Optionee) any of those unvested shares.  The terms upon
which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right.  The Plan Administrator may not
impose a vesting schedule upon any option grant or any shares of Common Stock
subject to the option which is more restrictive than twenty percent (20%) per
year vesting, with the initial vesting to occur one (1) year after the option
grant date.  However, this minimum vesting requirement shall not be applicable
with respect to any option granted to a Highly-Compensated Person.

               F.   FIRST REFUSAL RIGHTS.  Until such time as the Common Stock
is first registered under Section 12(g) of the 1934 Act, the Corporation shall
have the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan.  Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

               G.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of
the Optionee, the option shall be exercisable only by the Optionee and shall not
be assignable or transferable other than by will or by the laws of descent and
distribution following the Optionee's death.  However, a Non-Statutory Option
may be assigned in whole or in part during Optionee's lifetime in accordance
with the terms of a Qualified Domestic Relations Order.  The assigned portion
may only be exercised by the person or persons who acquire a proprietary
interest in the option pursuant to such Qualified Domestic Relations Order.  The
terms  applicable to the assigned portion shall be the same as those in effect
for the

                                       5.

<PAGE>

option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.


               H.   WITHHOLDING.  The Corporation's obligation to deliver shares
of Common Stock upon the exercise of any options granted under the Plan shall be
subject to the satisfaction of all applicable Federal, state and local income
and employment tax withholding requirements.

     II.       INCENTIVE OPTIONS

               The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options.  Options which
are specifically designated as Non-Statutory Options shall NOT be subject to the
terms specified in this Section II.

               A.   ELIGIBILITY.  Incentive Options may only be granted to
Employees.

               B.   EXERCISE PRICE.  The exercise price per share shall not be
less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

               C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one (1) calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000).  To
the extent the Employee holds two (2) or more such options which become
exercisable for the first time in the same calendar year, the foregoing
limitation on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

               D.   10% SHAREHOLDER.  If any Employee to whom an Incentive
Option is granted is a 10% Shareholder, then the option term shall not exceed
five (5) years measured from the option grant date.

     III.      CORPORATE TRANSACTION

               A.   In the event of any Corporate Transaction, each outstanding
option shall terminate and cease to be outstanding, except to the extent assumed
by the successor corporation (or parent thereof) in connection with such
Corporate Transaction.  In addition, all outstanding repurchase rights under the
Plan shall terminate automatically in the event of any Corporate Transaction,
except to the extent the repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction.

                                       6.

<PAGE>

               B.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in the consummation of such Corporate Transaction,
had the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be made to (i) the number and class of
securities available for issuance under the Plan following the consummation of
such Corporate Transaction and (ii) the exercise price payable per share under
each outstanding option, PROVIDED the aggregate exercise price payable for such
securities shall remain the same.

               C.   The grant of options under the Plan shall in no way affect
the right of the Corporation to adjust, reclassify, reorganize or otherwise
change its capital or business structure or to merge, consolidate, dissolve,
liquidate or sell or transfer all or any part of its business or assets.

     IV.       CANCELLATION AND REGRANT OF OPTIONS

               The Plan Administrator shall have the authority to effect, at any
time and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Plan and to grant in
substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                                  ARTICLE THREE

                                  MISCELLANEOUS


     I.        FINANCING

               The Plan Administrator may permit any Optionee to pay the option
exercise price by delivering a promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  Promissory notes may be authorized with or without
security or collateral.  However, any promissory notes delivered by a consultant
must be secured by property other than the purchased shares of Common Stock.  In
all events, the maximum credit available to each Optionee may not exceed the SUM
of (i) the aggregate option exercise price payable for the purchased shares plus
(ii) any Federal, state and local income and employment tax liability incurred
by the Optionee in connection with the option exercise.

                                       7.

<PAGE>


     II.       ADDITIONAL AUTHORITY

               A.   The Plan Administrator shall have the discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding:

                      (i)     to extend the period of time for which the
     option is to remain exercisable following the Optionee's cessation of
     Service or death from the limited period otherwise in effect for that
     option to such greater period of time as the Plan Administrator shall
     deem appropriate; PROVIDED, that in no event shall such option be
     exercisable after the specified expiration of the option term, and/or

                     (ii)     to permit the option to be exercised, during
     the applicable post-Service exercise period, not only with respect to
     the number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service or
     death but also with respect to one or more additional installments in
     which the Optionee would have vested under the option had the Optionee
     continued in Service.

     III.      EFFECTIVE DATE AND TERM OF THE PLAN

               A.   The Plan shall become effective when adopted by the Board,
but no option granted under the Plan may be exercised until the Plan is approved
by the Corporation's shareholders.  If such shareholder approval is not obtained
within twelve (12) months after the date of the Board's adoption of the Plan,
then all options previously granted under the Plan shall terminate and cease to
be outstanding, and no further options shall be granted.  Subject to such
limitation, the Plan Administrator may grant options under the Plan at any time
after the effective date of the Plan and before the date fixed herein for
termination of the Plan.

               B.   The Plan shall terminate upon the EARLIEST of (i) the
expiration of the ten (10)-year period measured from the date the Plan is
adopted by the Board, (ii) the date on which all shares available for issuance
under the Plan shall have been issued or (iii) the termination of all
outstanding options in connection with a Corporate Transaction.  Upon such Plan
termination, all options and unvested stock issuances outstanding under the Plan
shall continue to have full force and effect in accordance with the provisions
of the documents evidencing such options or issuances.

     IV.       AMENDMENT OF THE PLAN

               A.   The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects.  However, no such
amendment or modification shall, without the consent of the Optionees, adversely
affect their rights and obligations under their outstanding options.  In
addition, the Board shall not, without the

                                       8.

<PAGE>

approval of the Corporation's shareholders, (i) increase the maximum number of
shares issuable under the Plan, except for permissible adjustments in the event
of certain changes in the Corporation's capitalization, (ii) materially modify
the eligibility requirements for Plan participation or (iii) materially increase
the benefits accruing to Plan participants.

               B.   Options may be granted under the Plan to purchase shares of
Common Stock in excess of the number of shares then available for issuance under
the Plan, provided any such options actually granted may not be exercised until
there is obtained shareholder approval of an amendment sufficiently increasing
the number of shares of Common Stock available for issuance under the Plan.  If
such shareholder  approval is not obtained within twelve (12) months after the
date the excess grants are first made, then any options granted on the basis of
such excess shares shall terminate and cease to be outstanding.

     V.        USE OF PROCEEDS

               Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

     VI.       REGULATORY APPROVALS


               The implementation of the Plan, the granting of any option
hereunder and the issuance of any shares of Common Stock upon the exercise of
any option shall be subject to the Corporation's procurement of all approvals
and permits required by regulatory authorities having jurisdiction over the
Plan, the options granted under it and the shares of Common Stock issued
pursuant to it.

     VII.      NO EMPLOYMENT OR SERVICE RIGHTS

               Nothing in the Plan shall confer upon the Optionee any right to
continue in Service for any period of specific duration or interfere with or
otherwise restrict in any way the rights of the Corporation (or any Parent or
Subsidiary employing or retaining Optionee) or of the Optionee, which rights are
hereby expressly reserved by each, to terminate the Optionee's Service at any
time for any reason, with or without cause.

     VIII.     FINANCIAL REPORTS

               The Corporation shall deliver a balance sheet and an income
statement at least annually to each individual holding an outstanding option
under the Plan, unless such individual is a key Employee whose duties in
connection with the Corporation (or any Parent or Subsidiary) assure such
individual access to equivalent information.

                                STOCK OPTION AGREEMENT



RECITALS

    A.   The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or the board
of directors of any Parent or Subsidiary and consultants who provide services to
the Corporation (or any Parent or Subsidiary).

    B.   Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

    C.   All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

         NOW, THEREFORE, it is hereby agreed as follows:

         1.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice.  The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

         2.   OPTION TERM.  This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5, 6 or 17.

         3.   LIMITED TRANSFERABILITY.  This option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.  However, if this option is designated a
Non-Statutory Option in the Grant Notice, then this option may also be assigned
in whole or in part during Optionee's lifetime in accordance with the terms of a
Qualified Domestic Relations Order.  The assigned position shall be exercisable
only by the person or persons who acquire a proprietary interest in the option
pursuant to such Qualified Domestic Relations Order.  The terms applicable to
the assigned portion shall be the same as those in effect for this option
immediately prior to such assignment and shall be set forth in such documents
issued to the assignee as the Plan Administrator may deem appropriate.

<PAGE>

         4.   DATES OF EXERCISE.  This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice.  As
the option becomes exercisable for such installments, those installments shall
accumulate and the option shall remain exercisable for the accumulated
installments until the Expiration Date or sooner termination of the option term
under Paragraph 5, 6 or 17.

         5.   CESSATION OF SERVICE.  The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable:

              (a)  Should Optionee cease to remain in Service for any reason
(other than death or Disability) while this option is outstanding, then Optionee
shall have a period of three (3) months (commencing with the date of such
cessation of Service) during which to exercise this option, but in no event
shall this option be exercisable at any time after the Expiration Date.

              (b)  Should Optionee die while this option is outstanding, then
the personal representative of Optionee's estate or the person or persons to
whom the option is transferred pursuant to Optionee's will or in accordance with
the laws of descent and distribution shall have the right to exercise this
option.  Such right shall lapse and this option shall cease to be outstanding
upon the EARLIER of (i) the expiration of the twelve (12)- month period measured
from the date of Optionee's death or (ii) the Expiration Date.

              (c)  Should Optionee cease Service by reason of Disability while
this option is outstanding, then Optionee shall have a period of six (6) months
(commencing with the date of such cessation of Service) during which to exercise
this option.  However, should such Disability be deemed to constitute Permanent
Disability, then the period during which this option is to remain exercisable
shall be extended by an additional six (6) months so that the exercise period
shall be the twelve (12)-month period following the date of Optionee's cessation
of Service by reason of such Permanent Disability.  In no event shall this
option be exercisable at any time after the Expiration Date.

         NOTE:  Exercise of this option on a date later than three (3) months
         following cessation of Service due to Disability will result in loss
         of favorable Incentive Option treatment, UNLESS such Disability
         constitutes Permanent Disability.  In the event that Incentive Option
         treatment is not available, this option will be taxed as a
         Non-Statutory Option upon exercise.

              (d)  During the limited period of post-Service exercisability,
this option may not be exercised in the aggregate for more than the number of
vested Option Shares for which the option is exercisable at the time of
Optionee's cessation of Service.  Upon the expiration of such limited exercise
period or (if earlier) upon the Expiration Date, this option shall terminate and
cease to be outstanding for any vested Option Shares for


                                          2.


<PAGE>

which the option has not been exercised.  To the extent Optionee is not vested
in the Option Shares at the time of Optionee's cessation of Service, this option
shall immediately terminate and cease to be outstanding with respect to those
shares.

         6.   SPECIAL TERMINATION OF OPTION.

              (a)  In the event of a Corporate Transaction, this option shall
terminate and cease to be outstanding, except to the extent assumed by the
successor corporation or parent thereof in connection with such Corporate
Transaction.

              (b)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, PROVIDED the aggregate Exercise Price shall remain the same.

              (c)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

         7.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be made to (i) the total number
and/or class of securities subject to this option and (ii) the Exercise Price in
order to reflect such change and thereby preclude a dilution or enlargement of
benefits hereunder.

         8.   SHAREHOLDER RIGHTS.  The holder of this option shall not have any
shareholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

         9.   MANNER OF EXERCISING OPTION.

              (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                    (i)      Execute and deliver to the Corporation a Purchase
    Agreement for the Option Shares for which the option is exercised.


                                          3.


<PAGE>

                   (ii)      Pay the aggregate Exercise Price for the purchased
    shares in one or more of the following forms:

                        (A)  cash or check made payable to the Corporation; or

                        (B)  a promissory note payable to the Corporation, but
         only to the extent authorized by the Plan Administrator in accordance
         with Paragraph 14.

              Should the Common Stock be registered under Section 12(g) of the
         1934 Act at the time the option is exercised, then the Exercise Price
         may also be paid as follows:

                        (C)  in shares of Common Stock held by Optionee (or any
         other person or persons exercising the option) for the requisite
         period necessary to avoid a charge to the Corporation's earnings for
         financial reporting purposes and valued at Fair Market Value on the
         Exercise Date; or

                        (D)  to the extent the option is exercised for vested
         Option Shares, through a special sale and remittance procedure
         pursuant to which Optionee (or any other person or persons exercising
         the option) shall concurrently provide irrevocable written
         instructions (a) to a Corporation-designated brokerage firm to effect
         the immediate sale of the purchased shares and remit to the
         Corporation, out of the sale proceeds available on the settlement
         date, sufficient funds to cover the aggregate Exercise Price payable
         for the purchased shares plus all applicable Federal, state and local
         income and employment taxes required to be withheld by the Corporation
         by reason of such exercise and (b) to the Corporation to deliver the
         certificates for the purchased shares directly to such brokerage firm
         in order to complete the sale.

              Except to the extent the sale and remittance procedure is
         utilized in connection with the option exercise, payment of the
         Exercise Price must accompany the Purchase Agreement delivered to the
         Corporation in connection with the option exercise.

                   (iii)     Furnish to the Corporation appropriate
    documentation that the person or persons exercising the option (if other
    than Optionee) have the right to exercise this option.

                    (iv)     Execute and deliver to the Corporation such
    written representations as may be requested by the Corporation in order


                                          4.


<PAGE>

    for it to comply with the applicable requirements of Federal and state
    securities laws.

                     (v)     Make appropriate arrangements with the Corporation
    (or Parent or Subsidiary employing or retaining Optionee) for the
    satisfaction of all Federal, state and local income and employment tax
    withholding requirements applicable to the option exercise.

              (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.

              (c)  In no event may this option be exercised for any fractional
shares.

         10.  REPURCHASE RIGHTS.  ALL OPTION SHARES ACQUIRED UPON THE EXERCISE
OF THIS OPTION SHALL BE SUBJECT TO CERTAIN RIGHTS OF THE CORPORATION AND ITS
ASSIGNS TO REPURCHASE THOSE SHARES IN ACCORDANCE WITH THE TERMS SPECIFIED IN THE
PURCHASE AGREEMENT.

         11.  COMPLIANCE WITH LAWS AND REGULATIONS.

              (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

              (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.

         12.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the
benefit of, and be binding upon, the Corporation and its successors and assigns
and Optionee, Optionee's assigns and the legal representatives, heirs and

Corporation under the terms of this Agreement shall be in writing and addressed

shall be deemed effective upon personal delivery or upon deposit in the U.S.
mail, postage prepaid and properly addressed to the party to be notified.

         14.  FINANCING.  The Plan Administrator may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a promissory note.
The terms of any such promissory note (including the interest rate, the
requirements for collateral and the terms of repayment) shall be established by
the Plan Administrator in its sole discretion.(1)

         15.  CONSTRUCTION.  This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan.  All decisions of the Plan Administrator with
respect to any question or issue arising under the Plan or this Agreement shall
be conclusive and binding on all persons having an interest in this option.

         16.  GOVERNING LAW.  The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of California
without resort to that State's conflict-of-laws rules.

         17.  SHAREHOLDER APPROVAL.

              (a)  The grant of this option is subject to approval of the Plan
by the Corporation's shareholders within twelve (12) months after the adoption
of the Plan by the Board.  NOTWITHSTANDING ANY PROVISION OF THIS AGREEMENT TO
THE CONTRARY, THIS OPTION MAY NOT BE EXERCISED IN WHOLE OR IN PART UNTIL SUCH
SHAREHOLDER APPROVAL IS OBTAINED.  In the event that such shareholder approval
is not obtained, then this option shall terminate in its entirety and Optionee
shall have no further rights to acquire any Option Shares hereunder.

              (b)  If the Option Shares covered by this Agreement exceed, as of
the Grant Date, the number of shares of Common Stock which may without
shareholder approval be issued under the Plan, then this option shall be void
with respect to such excess shares, unless shareholder approval of an amendment
sufficiently increasing the number of shares of Common Stock issuable under the
Plan is obtained in accordance with the provisions of the Plan.

         18.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION.  In the event
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:


- ---------------
(1) Authorization of payment of the Exercise Price by a promissory note may,
under currently proposed Treasury Regulations, result in the loss of incentive
stock option treatment under the Federal tax laws.


                                          6.

<PAGE>

              (a)  This option shall cease to qualify for favorable tax
treatment as an Incentive Option if (and to the extent) this option is exercised
for one or more Option Shares: (i) more than three (3) months after the date
Optionee ceases to be an Employee for any reason other than death or Permanent
Disability or (ii) more than twelve (12) months after the date Optionee ceases
to be an Employee by reason of Permanent Disability.

              (b)  This option shall not become exercisable in the calendar
year in which granted if (and to the extent) the aggregate Fair Market Value
(determined at the Grant Date) of the Common Stock for which this option would
otherwise first become exercisable in such calendar year would, when added to
the aggregate value (determined as of the respective date or dates of grant) of
the Common Stock and any other securities for which one or more other Incentive
Options granted to Optionee prior to the Grant Date (whether under the Plan or
any other option plan of the Corporation or any Parent or Subsidiary) first
become exercisable during the same calendar year, exceed One Hundred Thousand
Dollars ($100,000) in the aggregate.  To the extent the exercisability of this
option is deferred by reason of the foregoing limitation, the deferred portion
shall become exercisable in the first calendar year or years thereafter in which
the One Hundred Thousand Dollar ($100,000) limitation of this Paragraph 18(b)
would not be contravened, but such deferral shall in all events end immediately
prior to the effective date of a Corporate Transaction in which this option is
not to be assumed, whereupon the option shall become immediately exercisable as
a Non-Statutory Option for the deferred portion of the Option Shares.

              (c)  Should Optionee hold, in addition to this option, one or
more other options to purchase Common Stock which become exercisable for the
first time in the same calendar year as this option, then the foregoing
limitations on the exercisability of such options as Incentive Options shall be
applied on the basis of the order in which such options are granted.

Purchased Shares  which are subject to the Repurchase Right shall be held in
escrow in accordance with the provisions of this Agreement.

         4.   SHAREHOLDER RIGHTS.  Until such time as the Corporation exercises
the Repurchase Right, the First Refusal Right or the Special Purchase Right,
Optionee (or any successor in interest) shall have all the rights of a
shareholder (including voting, dividend and liquidation rights) with respect to
the Purchased Shares, including the Purchased Shares held in escrow hereunder,
subject, however, to the transfer restrictions of Articles B and C.

    B.   SECURITIES LAW COMPLIANCE

         1.   RESTRICTED SECURITIES.  The Purchased Shares have not been
registered under the 1933 Act and are being issued to Optionee in reliance upon
the exemption from such registration provided by SEC Rule 701 for stock
issuances under compensatory benefit plans such as the Plan.  Optionee hereby
confirms that Optionee has been informed that the Purchased Shares are
restricted securities under the 1933 Act and may not be resold or transferred
unless the Purchased Shares are first registered under the Federal securities
laws or unless an exemption from such registration is available.  Accordingly,
Optionee hereby acknowledges that Optionee is prepared to hold the Purchased
Shares for an indefinite period and that Optionee is aware that SEC Rule 144
issued under the 1933 Act which exempts certain resales of unrestricted
securities is not presently available to exempt the resale of the Purchased
Shares from the registration requirements of the 1933 Act.

         2.   RESTRICTIONS ON DISPOSITION OF PURCHASED SHARES.  Optionee shall
make no disposition of the Purchased Shares (other than a Permitted Transfer)
unless and until there is compliance with all of the following requirements:

              (i)    Optionee shall have provided the Corporation with a
    written summary of the terms and conditions of the proposed
    disposition.

              (ii)   Optionee shall have complied with all requirements of
    this Agreement applicable to the disposition of the Purchased Shares.

              (iii)  Optionee shall have provided the Corporation with
    written assurances, in form and substance satisfactory to the
    Corporation, that (a) the proposed disposition does not require
    registration of the Purchased Shares under the 1933 Act or (b) all
    appropriate action necessary for compliance with the registration
    requirements of the 1933 Act or any exemption from registration
    available under the 1933 Act (including Rule 144) has been taken.

              (iv)   Optionee shall have provided the Corporation with
    written assurances, in form and substance satisfactory to the
    Corporation, that the proposed disposition will not result in the
    contravention of any transfer restrictions applicable to the Purchased
    Shares pursuant to the provisions of the Rules of the California
    Corporations Commissioner identified in Paragraph B.4.

         The Corporation shall NOT be required (i) to transfer on its books any
Purchased Shares which have been sold or transferred in violation of the
provisions of this Agreement OR (ii) to treat as the owner of the Purchased
Shares, or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Purchased Shares have been transferred in contravention
of this Agreement.


                                          2.

<PAGE>

         3.   RESTRICTIVE LEGENDS.  The stock certificates for the Purchased
Shares shall be endorsed with one or more of the following restrictive legends:

              (i)    "The shares represented by this certificate have not
    been registered under the Securities Act of 1933.  The shares may not
    be sold or offered for sale in the absence of (a) an effective
    registration statement for the shares under such Act, (b) a 'no
    action' letter of the Securities and Exchange Commission with respect
    to such sale or offer or (c) satisfactory assurances to the
    Corporation that registration under such Act is not required with
    respect to such sale or offer."

              (ii)   "It is unlawful to consummate a sale or transfer of
    this security, or any interest therein, or to receive any
    consideration therefor, without the prior written consent of the
    Commissioner of Corporations of the State of California, except as
    permitted in the Commissioner's Rules."

              (iii)  "The shares represented by this certificate are
    subject to certain repurchase rights and rights of first refusal
    granted to the Corporation and accordingly may not be sold, assigned,
    transferred, encumbered, or in any manner disposed of except in
    conformity with the terms of a written agreement dated ____________,
    199__ between the Corporation and the registered holder of the shares
    (or the predecessor in interest to the shares).  A copy of such
    agreement is maintained at the Corporation's principal corporate
    offices."

         4.   RECEIPT OF COMMISSIONER RULES.  Optionee hereby acknowledges
receipt of a copy of Section 260.141.11 of the Rules of the California
Corporations Commissioner, a copy of which is attached as Exhibit II to this
Agreement.

    C.   TRANSFER RESTRICTIONS

         1.   RESTRICTION ON TRANSFER.  Except for any Permitted Transfer,
Optionee shall not transfer, assign, encumber or otherwise dispose of any of the
Purchased Shares which are subject to the Repurchase Right.  In addition,
Purchased Shares which are released from the Repurchase Right shall not be
transferred, assigned, encumbered or otherwise disposed of in contravention of
the First Refusal Right, the Market Stand-Off or the Special Purchase Right.

         2.   TRANSFEREE OBLIGATIONS.  Each person (other than the Corporation)
to whom the Purchased Shares are transferred by means of a Permitted Transfer
must, as a condition precedent to the validity of such transfer, acknowledge in
writing to the Corporation that such person is bound by the provisions of this
Agreement and that the transferred shares are subject to (i) the Repurchase
Right, (ii) the First Refusal Right and (iii) the Market Stand-Off, to the same
extent such shares would be so subject if retained by Optionee.


                                          3.

<PAGE>

         3.   MARKET STAND-OFF.

              (a)  In connection with any underwritten public offering by the
Corporation of its equity securities pursuant to an effective registration
statement filed under the 1933 Act, including the Corporation's initial public
offering, Owner shall not sell, make any short sale of, loan, hypothecate,
pledge, grant any option for the purchase of, or otherwise dispose or transfer
for value or otherwise agree to engage in any of the foregoing transactions with
respect to, any Purchased Shares without the prior written consent of the
Corporation or its underwriters.  Such restriction (the "Market Stand-Off")
shall be in effect for such period of time from and after the effective date of
the final prospectus for the offering as may be requested by the Corporation or
such underwriters.  In no event, however, shall such period exceed one hundred
eighty (180) days and the Market Stand-Off shall in all events terminate two (2)
years after the effective date of the Corporation's initial public offering.

              (b)  Owner shall be subject to the Market Stand-Off PROVIDED AND
ONLY IF the officers and directors of the Corporation are also subject to
similar restrictions.

              (c)  Any new, substituted or additional securities which are by
reason of any Recapitalization or Reorganization distributed with respect to the
Purchased Shares shall be immediately subject to the Market Stand-Off, to the
same extent the Purchased Shares are at such time covered by such provisions.

              (d)  In order to enforce the Market Stand-Off, the Corporation
may impose stop-transfer instructions with respect to the Purchased Shares until
the end of the applicable stand-off period.

    D.   REPURCHASE RIGHT

         1.   GRANT.  The Corporation is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60)-day period
following the date Optionee ceases for any reason to remain in Service or (if
later) during the sixty (60)-day period following the execution date of this
Agreement, to repurchase at the Exercise Price all or (at the discretion of the
Corporation and with the consent of Optionee) any portion of the Purchased
Shares in which Optionee is not, at the time of his or her cessation of Service,
vested in accordance with the Vesting Schedule set forth in the Notice of Grant
or as otherwise provided in paragraph D.6 (such shares to be hereinafter
referred to as the "Unvested Shares").

         2.   EXERCISE OF THE REPURCHASE RIGHT.  The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60)-day exercise period.  The notice shall
indicate the number of Unvested Shares to be repurchased and the date on which
the repurchase is to be effected, such date to be not more than thirty (30) days
after the date of such notice.  The certificates


                                          4.

<PAGE>

representing the Unvested Shares to be repurchased shall be delivered to the
Corporation prior to the close of business on the date specified for the
repurchase.  Concurrently with the receipt of such stock certificates, the
Corporation shall pay to Owner, in cash or cash equivalents (including the
cancellation of any purchase-money indebtedness), an amount equal to the
Exercise Price previously paid for the Unvested Shares which are to be
repurchased from Owner.

         3.   TERMINATION OF THE REPURCHASE RIGHT.  The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph D.2.  In addition, the Repurchase Right shall
terminate and cease to be exercisable with respect to any and all Purchased
Shares in which Optionee vests in accordance with the Vesting Schedule set forth
in the Notice of Grant or as otherwise provided in Paragraph D.6.  All Purchased
Shares as to which the Repurchase Right lapses shall, however, remain subject to
(i) the First Refusal Right, (ii) the Market Stand-Off and (iii) the Special
Purchase Right.

         4.   AGGREGATE VESTING LIMITATION.  If the Option is exercised in more
than one increment so that Optionee is a party to one or more other Stock
Purchase Agreements (the "Prior Purchase Agreements") which are executed prior
to the date of this Agreement, then the total number of Purchased Shares as to
which Optionee shall be deemed to have a fully-vested interest under this
Agreement and all Prior Purchase Agreements shall not exceed in the aggregate
the number of Purchased Shares in which Optionee would otherwise at the time be
vested, in accordance with the Vesting Schedule, had all the Purchased Shares
(including those acquired under the Prior Purchase Agreements) been acquired
exclusively under this Agreement.

         5.   RECAPITALIZATION.  Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right, but only
to the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments to reflect such distribution shall be made to the number
and/or class of Purchased Shares subject to this Agreement and to the price per
share to be paid upon the exercise of the Repurchase Right in order to reflect
the effect of any such Recapitalization upon the Corporation's capital
structure; PROVIDED, however, that the aggregate purchase price shall remain the
same.

         6.   CORPORATE TRANSACTION.

              (a)  Immediately prior to the consummation of any Corporate
Transaction, the Repurchase Right shall automatically lapse in its entirety,
except to the extent the Repurchase Right is to be assigned to the successor
corporation (or parent thereof) in connection with the Corporate Transaction.


                                          5.

<PAGE>

              (b)  To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to the new capital
stock or other property (including any cash payment) received in exchange for
the Purchased Shares in consummation of the Corporate Transaction, but only to
the extent the Purchased Shares are at the time covered by such right.
Appropriate adjustments shall be made to the price per share payable upon
exercise of the Repurchase Right to reflect the effect of the Corporate
Transaction upon the Corporation's capital structure; PROVIDED, however, that
the aggregate purchase price shall remain the same.

    E.   RIGHT OF FIRST REFUSAL

         1.   GRANT.  The Corporation is hereby granted the right of first
refusal (the "First Refusal Right"), exercisable in connection with any proposed
transfer of the Purchased Shares in which Optionee has vested in accordance with
the Vesting Schedule.  For purposes of this Article E, the term "transfer" shall
include any sale, assignment, pledge, encumbrance or other disposition of the
Purchased Shares intended to be made by Owner, but shall not include any
Permitted Transfer.

         2.   NOTICE OF INTENDED DISPOSITION.  In the event any Owner of
Purchased Shares in which Optionee has vested desires to accept a bona fide
third-party offer for the transfer of any or all of such shares (the Purchased
Shares subject to such offer to be hereinafter referred to as the "Target
Shares"), Owner shall promptly (i) deliver to the Corporation written notice
(the "Disposition Notice") of the terms of the offer, including the purchase
price and the identity of the third-party offeror, and (ii) provide satisfactory
proof that the disposition of the Target Shares to such third-party offeror
would not be in contravention of the provisions set forth in Articles B and C.

         3.   EXERCISE OF THE FIRST REFUSAL RIGHT.  The Corporation shall, for
a period of twenty-five (25) days following receipt of the Disposition Notice,
have the right to repurchase any or all of the Target Shares subject to the
Disposition Notice upon the same terms as those specified therein or upon such
other terms (not materially different from those specified in the Disposition
Notice) to which Owner consents.  Such right shall be exercisable by delivery of
written notice (the "Exercise Notice") to Owner prior to the expiration of the
twenty-five (25)-day exercise period.  If such right is exercised with respect
to all the Target Shares, then the Corporation shall effect the repurchase of
such shares, including payment of the purchase price, not more than five (5)
business days after delivery of the Exercise Notice; and at such time the
certificates representing the Target Shares shall be delivered to the
Corporation.

         Should the purchase price specified in the Disposition Notice be
payable in property other than cash or evidences of indebtedness, the
Corporation shall have the right to pay the purchase price in the form of cash
equal in amount to the value of such property.  If Owner and the Corporation
cannot agree on such cash value within ten (10) days after the Corporation's
receipt of the Disposition Notice, the valuation shall be made by an


                                          6.

<PAGE>

appraiser of recognized standing selected by Owner and the Corporation or, if
they cannot agree on an appraiser within twenty (20) days after the
Corporation's receipt of the Disposition Notice, each shall select an appraiser
of recognized standing and the two (2) appraisers shall designate a third
appraiser of recognized standing, whose appraisal shall be determinative of such
value.  The cost of such appraisal shall be shared equally by Owner and the
Corporation.  The closing shall then be held on the LATER of (i) the fifth (5th)
business day following delivery of the Exercise Notice or (ii) the fifth (5th)
business day after such valuation shall have been made.

         4.   NON-EXERCISE OF THE FIRST REFUSAL RIGHT.  In the event the
Exercise Notice is not given to Owner prior to the expiration of the twenty-five
(25)-day exercise period, Owner shall have a period of thirty (30) days
thereafter in which to sell or otherwise dispose of the Target Shares to the
third-party offeror identified in the Disposition Notice upon terms (including
the purchase price) no more favorable to such third-party offeror than those
specified in the Disposition Notice; PROVIDED, however, that any such sale or
disposition must not be effected in contravention of the provisions of Articles
B and C.  The third-party offeror shall acquire the Target Shares free and clear
of the Repurchase Right and the First Refusal Right, but the acquired shares
shall remain subject to the provisions of Article B and Paragraph C.3.  In the
event Owner does not effect such sale or disposition of the Target Shares within
the specified thirty (30)-day period, the First Refusal Right shall continue to
be applicable to any subsequent disposition of the Target Shares by Owner until
such right lapses.

         5.   PARTIAL EXERCISE OF THE FIRST REFUSAL RIGHT.  In the event the
Corporation makes a timely exercise of the First Refusal Right with respect to a
portion, but not all, of the Target Shares specified in the Disposition Notice,
Owner shall have the option, exercisable by written notice to the Corporation
delivered within five (5) business days after Owner's receipt of the Exercise
Notice, to effect the sale of the Target Shares pursuant to either of the
following alternatives:

              (i)    sale or other disposition of all the Target Shares to
    the third-party offeror identified in the Disposition Notice, but in
    full compliance with the requirements of Paragraph E.4, as if the
    Corporation did not exercise the First Refusal Right; or

              (ii)   sale to the Corporation of the portion of the Target
    Shares which the Corporation has elected to purchase, such sale to be
    effected in substantial conformity with the provisions of Paragraph
    E.3.  The First Refusal Right shall continue to be applicable to any
    subsequent disposition of the remaining Target Shares until such right
    lapses.

         Failure of Owner to deliver timely notification to the Corporation
shall be deemed to be an election by Owner to sell the Target Shares pursuant to
alternative (i) above.


                                          7.

<PAGE>

         6.   RECAPITALIZATION/REORGANIZATION.

              (a)  Any new, substituted or additional securities or other
property which is by reason of any Recapitalization distributed with respect to
the Purchased Shares shall be immediately subject to the First Refusal Right,
but only to the extent the Purchased Shares are at the time covered by such
right.

              (b)  In the event of a Reorganization, the First Refusal Right
shall remain in full force and effect and shall apply to the new capital stock
or other property received in exchange for the Purchased Shares in consummation
of the Reorganization, but only to the extent the Purchased Shares are at the
time covered by such right.

         7.   LAPSE.  The First Refusal Right shall lapse upon the EARLIEST to
occur of (i) the first date on which shares of the Common Stock are held of
record by more than five hundred (500) persons, (ii) a determination is made by
the Board that a public market exists for the outstanding shares of Common Stock
or (iii) a firm commitment underwritten public offering, pursuant to an
effective registration statement under the 1933 Act, covering the offer and sale
of the Common Stock in the aggregate amount of at least ten million dollars
($10,000,000).  However, the Market Stand-Off shall continue to remain in full
force and effect following the lapse of the First Refusal Right.

    F.   MARITAL DISSOLUTION OR LEGAL SEPARATION

         1.   GRANT.  In connection with the dissolution of Optionee's marriage
or the legal separation of Optionee and Optionee's spouse, the Corporation shall
have the right (the "Special Purchase Right") to purchase from Optionee's
spouse, in accordance with the provisions of Paragraph F.3, all or any portion
of the Purchased Shares which would otherwise be awarded to such spouse in
settlement of any community property or other marital property rights such
spouse may have in such shares.

         2.   NOTICE OF DECREE OR AGREEMENT.  Optionee shall promptly provide
the Corporation with written notice (the "Dissolution Notice") of (i) the entry
of any judicial decree or order resolving the property rights of Optionee and
Optionee's spouse in connection with their marital dissolution or legal
separation or (ii) the execution of any contract or agreement relating to the
distribution or division of such property rights. The Dissolution Notice shall
be accompanied by a copy of the actual decree or order of dissolution or
contract or agreement between Optionee and Optionee's spouse which provides for
the award to the spouse of one or more Purchased Shares in settlement of any
community property or other marital property rights such spouse may have in such
shares.

         3.   EXERCISE OF THE SPECIAL PURCHASE RIGHT.  The Special Purchase
Right shall be exercisable by delivery of written notice (the "Purchase Notice")
to Optionee and Optionee's spouse within thirty (30) days after the
Corporation's receipt of the Dissolution Notice.  The Purchase Notice shall
indicate the number of shares to be purchased by the


                                          8.

<PAGE>

Corporation, the date such purchase is to be effected (such date to be not less
than five (5) business days, nor more than ten (10) business days, after the
date of the Purchase Notice) and the Fair Market Value to be paid for such
Purchased Shares.  Optionee (or Optionee's spouse, to the extent such spouse has
physical possession of the Purchased Shares) shall, prior to the close of
business on the date specified for the purchase, deliver to the Corporation the
certificates representing the shares to be purchased.  The Corporation shall,
concurrently with the receipt of the stock certificates, pay to Optionee's
spouse (in cash or cash equivalents) an amount equal to the Fair Market Value
specified for such shares in the Purchase Notice.

         If Optionee's spouse does not agree with the Fair Market Value
specified for the shares in the Purchase Notice, then the spouse shall promptly
notify the Corporation in writing of such disagreement and the fair market value
of such shares shall thereupon be determined by an appraiser of recognized
standing selected by the Corporation and the spouse.  If they cannot agree on an
appraiser within twenty (20) days after the date of the Purchase Notice, each
shall select an appraiser of recognized standing, and the two (2) appraisers
shall designate a third appraiser of recognized standing whose appraisal shall
be determinative of such value.  The cost of the appraisal shall be shared
equally by the Corporation and Optionee's spouse.  The closing shall then be
held on the fifth (5th) business day following the completion of such appraisal;
PROVIDED, however, that if the appraised value is more than twenty-five percent
(25%) greater than the Fair Market Value specified for the shares in the
Purchase Notice, the Corporation shall have the right, exercisable prior to the
expiration of such five (5) business-day period, to rescind the exercise of the
Special Purchase Right and thereby revoke its election to purchase the shares
awarded to the spouse.  In the event the Corporation so revokes its election,
the Corporation shall bear the entire cost of the appraisal.

         4.   LAPSE.  The Special Purchase Right shall lapse upon the EARLIER
to occur of (i) the lapse of the First Refusal Right or (ii) the expiration of
the exercise period specified in Paragraph F.3, to the extent the Special
Purchase Right is not timely exercised in accordance with such paragraph.

    G.   ESCROW

         1.   DEPOSIT.  Upon issuance, the certificates for the Purchased
Shares which are subject to the Repurchase Right shall be deposited in escrow
with the Corporation to be held in accordance with the provisions of this
Article G.  Each deposited certificate shall be accompanied by a duly-executed
Assignment Separate from Certificate in the form of Exhibit I.  The deposited
certificates, together with any other assets or securities from time to time
deposited with the Corporation pursuant to the requirements of this Agreement,
shall remain in escrow until such time or times as the certificates (or other
assets and securities) are to be released or otherwise surrendered for
cancellation in accordance with Paragraph G.3.  Upon delivery of the
certificates (or other assets and securities) to the


                                          9.

<PAGE>

Corporation, Owner shall be issued a receipt acknowledging the number of
Purchased Shares (or other assets and securities) delivered in escrow.

         2.   RECAPITALIZATION/REORGANIZATION.   Any new, substituted or
additional securities or other property which is by reason of any
Recapitalization or Reorganization distributed with respect to the Purchased
Shares shall be immediately delivered to the Corporation to be held in escrow
under this Article G, but only to the extent the Purchased Shares are at the
time subject to the escrow requirements hereunder.  However, all regular cash
dividends on the Purchased Shares (or other securities at the time held in
escrow) shall be paid directly to Owner and shall not be held in escrow.

         3.   RELEASE/SURRENDER.  The Purchased Shares, together with any other
assets or securities held in escrow hereunder, shall be subject to the following
terms relating to their release from escrow or their surrender to the
Corporation for repurchase and cancellation:

              (i)    Should the Corporation elect to exercise the
    Repurchase Right with respect to any Unvested Shares, then the
    escrowed certificates for those Unvested Shares (together with any
    other assets or securities attributable thereto) shall be surrendered
    to the Corporation concurrently with the payment to Owner of an amount
    equal to the aggregate Exercise Price for such Unvested Shares, and
    Owner shall cease to have any further rights or claims with respect to
    such Unvested Shares (or other assets or securities attributable
    thereto).

              (ii)   Should the Corporation elect to exercise the First
    Refusal Right with respect to any Target Shares held at the time in
    escrow hereunder, then the escrowed certificates for those Target
    Shares (together with any other assets or securities attributable
    thereto) shall be surrendered to the Corporation concurrently with the
    payment of the Paragraph E.3 purchase price for such Target Shares to
    Owner, and Owner shall cease to have any further rights or claims with
    respect to such Target Shares (or other assets or securities
    attributable thereto).

              (iii)  Should the Corporation elect NOT to exercise the
    Repurchase Right with respect to any Unvested Shares or the First
    Refusal Right with respect to any Target Shares held at the time in
    escrow hereunder, then the escrowed certificates for those shares
    (together with any other assets or securities attributable thereto)
    shall be released to Owner.

              (iv)   As the Purchased Shares (or any other assets or
    securities attributable thereto) vest in accordance with the Vesting
    Schedule, the certificates for those vested shares (as well as all
    other vested assets and

                                         10.

<PAGE>

    securities) shall be released from escrow upon Owner's request, but not
    more frequently than once every six (6) months.

              (v)    All Purchased Shares which vest (and any other vested
    assets and securities attributable thereto) shall be released within
    thirty (30) days after the EARLIER to occur of (a) Optionee's
    cessation of Service or (b) the lapse of the First Refusal Right.

              (vi)   All Purchased Shares (or other assets or securities)
    released from escrow shall nevertheless remain subject to (a) the
    First Refusal Right, to the extent such right has not otherwise
    lapsed, (b) the Market Stand-Off, until such restriction terminates,
    and (c) the Special Purchase Right, to the extent such right has not
    otherwise lapsed.

    H.   SPECIAL TAX ELECTION

         The acquisition of the Purchased Shares may result in adverse tax
consequences which may be mitigated by filing an election under Code Section
83(b).  Such election must be filed within thirty (30) days after the date of
this Agreement.  A description of the tax consequences applicable to the
acquisition of the Purchased Shares and the form for making the Code Section
83(b) election are set forth in Exhibit III.  OPTIONEE SHOULD CONSULT WITH HIS
OR HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING THE PURCHASED
SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE SECTION 83(b)
ELECTION.  OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE RESPONSIBILITY, AND
NOT THE CORPORATION'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(b), EVEN
IF OPTIONEE REQUESTS THE CORPORATION OR ITS REPRESENTATIVES TO MAKE THIS FILING
ON HIS OR HER BEHALF.

    I.   GENERAL PROVISIONS

         1.   ASSIGNMENT.  The Corporation may assign the Repurchase Right, the
First Refusal Right and/or the Special Purchase Right to any person or entity
selected by the Board, including (without limitation) one or more shareholders
of the Corporation.

         If the assignee of the Repurchase Right is other than (i) a wholly
owned subsidiary of the Corporation or (ii) the parent corporation owning one
hundred percent (100%) of the Corporation's outstanding capital stock, then such
assignee must make a cash payment to the Corporation, upon the assignment of the
Repurchase Right, in an amount equal to the excess (if any) of (i) the Fair
Market Value of the Purchased Shares at the time subject to the assigned
Repurchase Right over (ii) the aggregate repurchase price payable for the
Purchased Shares.


                                         11.

<PAGE>

         2.   NO EMPLOYMENT OR SERVICE CONTRACT.  Nothing in this Agreement or
in the Plan shall confer upon Optionee any right to continue in Service for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Parent or Subsidiary employing or
retaining Optionee) or of Optionee, which rights are hereby expressly reserved
by each, to terminate Optionee's Service at any time for any reason, with or
without cause.

         3.   NOTICES.  Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or upon
deposit in the U.S. mail, registered or certified, postage prepaid and properly
addressed to the party entitled to such notice at the address indicated below
such party's signature line on this Agreement or at such other address as such
party may designate by ten (10) days advance written notice under this paragraph
to all other parties to this Agreement.

         4.   NO WAIVER.  The failure of the Corporation in any instance to
exercise the Repurchase Right, the First Refusal Right or the Special Purchase
Right shall not constitute a waiver of any other repurchase rights and/or rights
of first refusal that may subsequently arise under the provisions of this
Agreement or any other agreement between the Corporation and Optionee or
Optionee's spouse.  No waiver of any breach or condition of this Agreement shall
be deemed to be a waiver of any other or subsequent breach or condition, whether
of like or different nature.

         5.   CANCELLATION OF SHARES.  If the Corporation shall make available,
at the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with the
provisions of this Agreement, then from and after such time, the person from
whom such shares are to be repurchased shall no longer have any rights as a
holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement).  Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Corporation shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

    J.   MISCELLANEOUS PROVISIONS

         1.   OPTIONEE UNDERTAKING.  Optionee hereby agrees to take whatever
additional action and execute whatever additional documents the Corporation may

entire contract between the parties hereto with regard to the subject matter

construed in accordance with, the laws of the State of California without resort
to that State's conflict-of-laws rules.

         4.   COUNTERPARTS.  This Agreement may be executed in counterparts,
each of which shall be deemed to be an original, but all of which together shall
constitute one and the same instrument.

         5.   SUCCESSORS AND ASSIGNS.  The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Corporation and its successors
and assigns and upon Optionee, Optionee's assigns and the legal representatives,
heirs and legatees of Optionee's estate, whether or not any such person shall
have become a party to this Agreement and have agreed in writing to join herein
and be bound by the terms hereof.

his or her true and lawful attorney in fact, for him or her and in his or her
name, place and stead, and for his or her use and benefit, to agree to any

                                  SECTION 260.141.11
                       TITLE 10, CALIFORNIA ADMINISTRATIVE CODE


         260.141.11 Restriction on Transfer.  (a) The issuer of any security
upon which a restriction on transfer has been imposed pursuant to Sections
260.102.6, 260.141.10 or 260.534 shall cause a copy of this section to be
delivered to each issuee or transferee of such security at the time the
certificate evidencing the security is delivered to the issuee or transferee.

         (b)   It is unlawful for the holder of any such security to consummate
a sale or transfer of such security, or any interest therein, without the prior
written consent of the Commissioner (until this condition is removed pursuant to
Section 260.141.12 of these rules), except:

         (1)   to the issuer;

         (2)   pursuant to the order or process of any court;

         (3)   to any person described in Subdivision (i) of Section 25102 of
the Code or Section 260.105.14 of these rules;

         (4)   to the transferor's ancestors, descendants or spouse, or any
custodian or trustee for the account of the transferor or the transferor's
ancestors, descendants, or spouse; or to a transferee by a trustee or custodian
for the account of the transferee or the transferee's ancestors, descendants or
spouse;

         (5)   to holders of securities of the same class of the same issuer;

         (6)   by way of gift or donation inter vivos or on death;

         (7)   by or through a broker-dealer licensed under the Code (either
acting as such or as a finder) to a resident of a foreign state, territory or
country who is neither domiciled in this state to the knowledge of the
broker-dealer, nor actually present in this state if the sale of such securities
is not in violation of any securities law of the foreign state, territory or
country concerned;

         (8)   to a broker-dealer licensed under the Code in a principal
transaction, or as an underwriter or member of an underwriting syndicate or
selling group;

         (9)   if the interest sold or transferred is a pledge or other lien
given by the purchaser to the seller upon a sale of the security for which the
Commissioner's written consent is obtained or under this rule not required;


                                        II-1.

<PAGE>

         (10)  by way of a sale qualified under Sections 25111, 25112, 25113 or
25121 of the Code, of the securities to be transferred, provided that no order
under Section 25140 or Subdivision (a) of Section 25143 is in effect with
respect to such qualification;

         (11)  by a corporation to a wholly owned subsidiary of such
corporation, or by a wholly owned subsidiary of a corporation to such
corporation;

who are neither domiciled nor actually present in this state;

         (14)  to the State Controller pursuant to the Unclaimed Property Law
or to the administrator of the unclaimed property law of another state; or

         (15)  by the State Controller pursuant to the Unclaimed Property Law
or by the administrator of the unclaimed property law of another state if, in

each purchaser a copy of this rule, and (iii) advises the Commissioner of the
name of each purchaser;

         (16)  by a trustee to a successor trustee when such transfer does not

issuer transaction that is subject to the qualification requirement of Section
25110 of the Code but exempt from that qualification requirement by subdivision
(f) of Section 25102; provided that any such transfer is on the condition that
any certificate evidencing the security issued to such transferee shall contain
the legend required by this section.

         (c)   The certificates representing all such securities subject to
such a restriction on transfer, whether upon initial issuance or upon any
transfer thereof, shall bear on their face a legend, prominently stamped or

INTEREST THEREIN, OR TO RECEIVE ANY CONSIDERATION THEREFOR, WITHOUT THE PRIOR
WRITTEN CONSENT OF THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA,
EXCEPT AS PERMITTED IN THE COMMISSIONER'S RULES."

                                     EXHIBIT III

                         FEDERAL INCOME TAX CONSEQUENCES AND
                              SECTION 83(b) TAX ELECTION

    I.   FEDERAL INCOME TAX CONSEQUENCES AND SECTION 83(b) ELECTION FOR
EXERCISE OF NON-STATUTORY OPTION.  If the Purchased Shares are acquired pursuant
to the exercise of a Non-Statutory Option, as specified in the Grant Notice,
then under Code Section 83, the excess of the Fair Market Value of the Purchased
Shares on the date any forfeiture restrictions applicable to such shares lapse
over the Exercise Price paid for such shares will be reportable as ordinary
income on the lapse date.  For this purpose, the term "forfeiture restrictions"
includes the right of the Corporation to repurchase the Purchased Shares
pursuant to the Repurchase Right.  However, Optionee may elect under Code
Section 83(b) to be taxed at the time the Purchased Shares are acquired, rather
than when and as such Purchased Shares cease to be subject to such forfeiture
restrictions.  Such election must be filed with the Internal Revenue Service
within thirty (30) days after the date of the Agreement.  Even if the Fair
Market Value of the Purchased Shares on the date of the Agreement equals the
Exercise Price paid (and thus no tax is payable), the election must be made to
avoid adverse tax consequences in the future.  The form for making this election
is attached as part of this exhibit.  FAILURE TO MAKE THIS FILING WITHIN THE
APPLICABLE THIRTY (30)-DAY PERIOD WILL RESULT IN THE RECOGNITION OF ORDINARY
INCOME BY OPTIONEE AS THE FORFEITURE RESTRICTIONS LAPSE.

    II.  FEDERAL INCOME TAX CONSEQUENCES AND CONDITIONAL SECTION 83(b) ELECTION
FOR EXERCISE OF INCENTIVE OPTION.  If the Purchased Shares are acquired pursuant
to the exercise of an Incentive Option, as specified in the Grant Notice, then
the following tax principles shall be applicable to the Purchased Shares:

               (i)    For regular tax purposes, no taxable income will be
    recognized at the time the Option is exercised.

               (ii)   The excess of (a) the Fair Market Value of the
    Purchased Shares on the date the Option is exercised or (if later) on
    the date any forfeiture restrictions applicable to the Purchased
    Shares lapse over (b) the Exercise Price paid for the Purchased Shares
    will be includible in Optionee's taxable income for alternative
    minimum tax purposes.

               (iii)  If Optionee makes a disqualifying disposition of the
    Purchased Shares, then Optionee will recognize ordinary income in the
    year of such disposition equal in amount to the excess of (a) the Fair
    Market Value of the Purchased Shares on the date the Option is
    exercised or (if later) on the date any forfeiture restrictions
    applicable to the Purchased Shares lapse over (b) the Exercise Price
    paid for the Purchased Shares.  Any additional gain recognized upon
    the disqualifying disposition will be either short-term or long-term
    capital gain depending upon the period for which the Purchased Shares
    are held prior to the disposition.


                                        III-1.

<PAGE>

               (iv)     For purposes of the foregoing, the term
    "forfeiture restrictions" will include the right of the Corporation to
    repurchase the Purchased Shares pursuant to the Repurchase Right.  The
    term "disqualifying disposition" means any sale or other
    disposition(1) of the Purchased Shares within two (2) years after the
    Grant Date or within one (1) year after the exercise date of the
    Option.

               (v)    In the absence of final Treasury Regulations relating
    to Incentive Options, it is not certain whether Optionee may, in
    connection with the exercise of the Option for any Purchased Shares at
    the time subject to forfeiture restrictions, file a protective
    election under Code Section 83(b) which would limit (a) Optionee's
    alternative minimum taxable income upon exercise and (b) Optionee's
    ordinary income upon a disqualifying disposition to the excess of the
    Fair Market Value of the Purchased Shares on the date the Option is
    exercised over the Exercise Price paid for the Purchased Shares.
    Accordingly, such election if properly filed will only be allowed to
    the extent the final Treasury Regulations permit such a protective
    election.  Page 2 of the attached form for making the election should
    be filed with any election made in connection with the exercise of an
    Incentive Option.



- ------------------------------
(1)  Generally, a disposition of shares purchased under an Incentive Option
includes any transfer of legal title, including a transfer by sale, exchange or
gift, but does not include a transfer to the Optionee's spouse, a transfer into
joint ownership with right of survivorship if Optionee remains one of the joint
owners, a pledge, a transfer by bequest or inheritance or certain tax free
exchanges permitted under the Code.

                                SECTION 83(b) ELECTION

         This statement is being made under Section 83(b) of the Internal
Revenue Code, pursuant to Treas. Reg. Section 1.83-2.

(1) The taxpayer who performed the services is:

    Name:

(2) The property with respect to which the election is being made is
     shares of the common stock of Vista Medical Technologies, Inc.

(3) The property was issued on              , 199  .

(4) The taxable year in which the election is being made is the calendar year
    199  .

(5) The property is subject to a repurchase right pursuant to which the issuer
    has the right to acquire the property at the original purchase price if for
    any reason taxpayer's employment with the issuer is terminated.  The
    issuer's repurchase right lapses in a series of annual and monthly
    installments over a four (4)-year period ending on             , 199  .

(6) The fair market value at the time of transfer (determined without regard to
    any restriction other than a restriction which by its terms will never
    lapse) is $             per share.

(7) The amount paid for such property is $             per share.

(8) A copy of this statement was furnished to Vista Medical Technologies, Inc.
    for whom taxpayer rendered the services underlying the transfer of
    property.

(9) This statement is executed on                        , 199  .

THIS ELECTION MUST BE FILED WITH THE INTERNAL REVENUE SERVICE CENTER WITH WHICH
TAXPAYER FILES HIS OR HER FEDERAL INCOME TAX RETURNS AND MUST BE MADE WITHIN
THIRTY (30) DAYS AFTER THE EXECUTION DATE OF THE STOCK PURCHASE AGREEMENT.  THIS
FILING SHOULD BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED.
OPTIONEE MUST RETAIN TWO (2) COPIES OF THE COMPLETED FORM FOR FILING WITH HIS OR
HER FEDERAL AND STATE TAX RETURNS FOR THE CURRENT TAX YEAR AND AN ADDITIONAL
COPY FOR HIS OR HER RECORDS.

<PAGE>

The property described in the above Section 83(b) election is comprised of
shares of common stock acquired pursuant to the exercise of an incentive stock
option under Section 422 of the Internal Revenue Code (the "Code").
Accordingly, it is the intent of the Taxpayer to utilize this election to
achieve the following tax results:

         1.    The purpose of this election is to have the alternative minimum
taxable income attributable to the purchased shares measured by the amount by
which the fair market value of such shares at the time of their transfer to the
Taxpayer exceeds the purchase price paid for the shares.  In the absence of this
election, such alternative minimum taxable income would be measured by the
spread between the fair market value of the purchased shares and the purchase
price which exists on the various lapse dates in effect for the forfeiture
restrictions applicable to such shares.  The election is to be effective to the
full extent permitted under the Code.

         2.    Section 421(a)(1) of the Code expressly excludes from income any
excess of the fair market value of the purchased shares over the amount paid for
such shares.  Accordingly, this election is also intended to be effective in the
event there is a "disqualifying disposition" of the shares, within the meaning
of Section 421(b) of the Code, which would otherwise render the provisions of
Section 83(a) of the Code applicable at that time.  Consequently, the Taxpayer
hereby elects to have the amount of disqualifying disposition income measured by
the excess of the fair market value of the purchased shares on the date of
transfer to the Taxpayer over the amount paid for such shares.  Since Section
421(a) presently applies to the shares which are the subject of this Section
83(b) election, no taxable income is actually recognized for regular tax
purposes at this time, and no income taxes are payable, by the Taxpayer as a
result of this election.


THIS PAGE 2 IS TO BE ATTACHED TO ANY SECTION 83(b) ELECTION FILED IN CONNECTION
WITH THE EXERCISE OF AN INCENTIVE STOCK OPTION UNDER THE FEDERAL TAX LAWS.

                            AS AMENDED MARCH 3, 1997

                        VISTA MEDICAL TECHNOLOGIES, INC.


                      1997 STOCK OPTION/STOCK ISSUANCE PLAN


                                   ARTICLE ONE

                               GENERAL PROVISIONS

    I.    PURPOSE OF THE PLAN

          This 1997 Stock Option/Stock Issuance Plan is intended to promote the
interests of Vista Medical Technologies, Inc., a Delaware corporation, by
providing eligible persons with the opportunity to acquire a proprietary
interest, or otherwise increase their proprietary interest, in the Corporation
as an incentive for them to remain in the service of the Corporation.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

   II.    STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into three separate equity programs:

               -    the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

               -    the Stock Issuance Program under which eligible persons may,
at the discretion of the Plan Administrator, be issued shares of Common Stock
directly, either through the immediate purchase of such shares or as a bonus for
services rendered the Corporation (or any Parent or Subsidiary), and

               -    the Automatic Option Grant Program under which eligible non-
employee Board members shall automatically receive option grants at periodic
intervals to purchase shares of Common Stock.

          B.   The provisions of Articles One and Five shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

  III.    ADMINISTRATION OF THE PLAN

<PAGE>

          A.   Prior to the Section 12 Registration Date, the Discretionary
Option Grant and Stock Issuance Programs shall be administered by the Board.
Beginning with the Section 12 Registration Date, the Primary Committee shall
have sole and exclusive authority to administer the Discretionary Option Grant
and Stock Issuance Programs with respect to Section 16 Insiders.

          B.   Administration of the Discretionary Option Grant and Stock
Issuance Programs with respect to all other persons eligible to participate in
those programs may, at the Board's discretion, be vested in the Primary
Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons.  The members of the
Secondary Committee may be Board members who are Employees eligible to receive
discretionary option grants or direct stock issuances under the Plan or any
other stock option, stock appreciation, stock bonus or other stock plan of the
Corporation (or any Parent or Subsidiary).

          C.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time.  The Board may also at any time terminate the functions
of any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          D.   Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of such programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable.  Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder.

          E.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee.  No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

          F.   Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to any
option grants or stock issuances made under this program.

   IV.    ELIGIBILITY


                                       -2-
<PAGE>

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                 (i)     Employees,

                (ii)     non-employee members of the Board or the board of
     directors of any Parent or Subsidiary, and

               (iii)     consultants and other independent advisors who
     provide services to the Corporation (or any Parent or Subsidiary).

          B.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive option grants, the time or times
when such option grants are to be made, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive Option
or a Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive stock issuances, the time or times when such issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
for such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

          D.   The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to non-employee Board members
who are elected or appointed to the Board after the Effective Date.  A non-
employee Board member who has previously been in the employ of the Corporation
(or any Parent or Subsidiary) shall not be eligible to receive an option grant
under the Automatic Option Grant Program at the time he or she first becomes a
non-employee Board member, but shall be eligible to receive periodic option
grants under the Automatic Option Grant Program while he or she continues to
serve as a non-employee Board member.

    V.    STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market.  The maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall not exceed
2,820,000 shares.


                                       -3-
<PAGE>

          B.   No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 50,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1997 calendar year.

          C.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent those options
expire or terminate for any reason prior to exercise in full.  Unvested shares
issued under the Plan and subsequently cancelled or repurchased by the
Corporation, at the original issue price paid per share, pursuant to the
Corporation's repurchase rights under the Plan shall be added back to the number
of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent option
grants or direct stock issuances under the Plan.  However, should the exercise
price of an option under the Plan be paid with shares of Common Stock or should
shares of Common Stock otherwise issuable under the Plan be withheld by the
Corporation in satisfaction of the withholding taxes incurred in connection with
the exercise of an option or the vesting of a stock issuance under the Plan,
then the number of shares of Common Stock available for issuance under the Plan
shall be reduced by the gross number of shares for which the option is exercised
or which vest under the stock issuance, and not by the net number of shares of
Common Stock issued to the holder of such option or stock issuance.
Notwithstanding the above, no additional adjustment shall be made to any shares
or class of shares with respect to any transaction occurring prior to the
completion of an offering of shares of the Common Stock of the Company to the
public pursuant to an effective registration statement.

          D.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under this Plan per calendar year, (iii) the number
and/or class of securities for which grants are subsequently to be made under
the Automatic Option Grant Program to new and continuing non-employee Board
members, (iv) the number and/or class of securities and the exercise price per
share in effect under each outstanding option under the Plan and (v) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from the Predecessor Plan.  Such adjustments
to the outstanding options are to be effected in a manner which shall preclude
the enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

                                   ARTICLE TWO

                       DISCRETIONARY OPTION GRANT PROGRAM


                                       -4-
<PAGE>

    I.    OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; PROVIDED, however, that each such document
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.

               1.   The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the option grant date, provided that
the Plan Administrator may fix the exercise price at less than 85% if the
optionee, at the time of the option grant, shall have made a payment to the
Company (including payment made by means of a salary reduction) equal to the
excess of the Fair Market Value of the Common Stock on the option grant date
over such exercise price.

               2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Five and the documents evidencing the option, be payable in one or more
of the forms specified below:

                 (i)     cash or check made payable to the Corporation,

                (ii)     shares of Common Stock held for the requisite
     period necessary to avoid a charge to the Corporation's earnings for
     financial reporting purposes and valued at Fair Market Value on the
     Exercise Date, or

               (iii)     to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to
     which the Optionee shall concurrently provide irrevocable written
     instructions to (a) a Corporation-designated brokerage firm to effect
     the immediate sale of the purchased shares and remit to the
     Corporation, out of the sale proceeds available on the settlement
     date, sufficient funds to cover the aggregate exercise price payable
     for the purchased shares plus all applicable Federal, state and local
     income and employment taxes required to be withheld by the Corporation
     by reason of such exercise and (b) the Corporation to deliver the
     certificates for the purchased shares directly to such brokerage firm
     in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option.  However, no


                                       -5-
<PAGE>

option shall have a term in excess of ten (10) years measured from the option
grant date.

          C.   EFFECT OF TERMINATION OF SERVICE.

               1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                 (i)     Any option outstanding at the time of the
     Optionee's cessation of Service for any reason shall remain
     exercisable for such period of time thereafter as shall be determined
     by the Plan Administrator and set forth in the documents evidencing
     the option, but no such option shall be exercisable after the
     expiration of the option term.

                (ii)     Any option exercisable in whole or in part by the
     Optionee at the time of death may be subsequently exercised by the
     personal representative of the Optionee's estate or by the person or
     persons to whom the option is transferred pursuant to the Optionee's
     will or in accordance with the laws of descent and distribution.

               (iii)     Should the Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to be outstanding.

                (iv)     During the applicable post-Service exercise
     period, the option may not be exercised in the aggregate for more than
     the number of vested shares for which the option is exercisable on the
     date of the Optionee's cessation of Service.  Upon the expiration of
     the applicable exercise period or (if earlier) upon the expiration of
     the option term, the option shall terminate and cease to be
     outstanding for any vested shares for which the option has not been
     exercised.  However, the option shall, immediately upon the Optionee's
     cessation of Service, terminate and cease to be outstanding to the
     extent the option is not otherwise at that time exercisable for vested
     shares.

               2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                (i)      extend the period of time for which the option is
     to remain exercisable following the Optionee's cessation of Service
     from the limited exercise period otherwise in effect for that option
     to such greater period of time as the Plan Administrator shall deem
     appropriate, but in no event beyond the expiration of the option term,
     and/or


                                       -6-
<PAGE>

                (ii)     permit the option to be exercised, during the
     applicable post-Service exercise period, not only with respect to the
     number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service but
     also with respect to one or more additional installments in which the
     Optionee would have vested had the Optionee continued in Service.

          D.   STOCKHOLDER RIGHTS.  The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   REPURCHASE RIGHTS.  The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.

          F.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death.  However, a Non-Statutory
Option may be assigned in whole or in part during the Optionee's lifetime.  The
assigned portion may only be exercised by the person or persons who acquire a
proprietary interest in the option pursuant to the assignment. The terms
applicable to the assigned portion shall be the same as those in effect for the
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.

   II.    INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Five shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall NOT be subject to the terms of this Section II.

          A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.


          B.   EXERCISE PRICE.  The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.


                                       -7-
<PAGE>

          C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000).  To the extent
the Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

          D.   10% STOCKHOLDER.  If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

  III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable with respect to the total number of shares of Common Stock at
the time subject to such option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock.  However, an outstanding option
shall not so accelerate if and to the extent:  (i) such option is, in connection
with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof), (ii) such option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
option shares at the time of the Corporate Transaction and provides for
subsequent payout in accordance with the same vesting schedule applicable to
those option shares or (iii) the acceleration of such option is subject to other
limitations imposed by the Plan Administrator at the time of the option grant.
The determination of option comparability under clause (i) above shall be made
by the Plan Administrator, and its determination shall be final, binding and
conclusive.

          B.   All outstanding repurchase rights shall terminate automatically,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.
          C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).


                                       -8-
<PAGE>

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
PROVIDED the aggregate exercise price payable for such securities shall remain
the same, (ii) the maximum number and/or class of securities available for
issuance over the remaining term of the Plan and (iii) the maximum number and/or
class of securities for which any one person may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances
under the Plan per calendar year.

          E.   The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionee's Service subsequently
terminates by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those options are assumed or replaced and do not
otherwise accelerate.  Any options so accelerated shall remain exercisable for
fully-vested shares until the EARLIER of (i) the expiration of the option term
or (ii) the expiration of the one (1)-year period measured from the effective
date of the Involuntary Termination.  In addition, the Plan Administrator may
provide that one or more of the Corporation's outstanding repurchase rights with
respect to shares held by the Optionee at the time of such Involuntary
Termination shall immediately terminate, and the shares subject to those
terminated repurchase rights shall accordingly vest in full.

          F.   The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionee's Service subsequently
terminates by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any Change
in Control.  Each option so accelerated shall remain exercisable for fully-
vested shares until the EARLIER of (i) the expiration of the option term or (ii)
the expiration of the one (1)-year period measured from the effective date of
the Involuntary Termination.  In addition, the Plan Administrator may provide
that one or more of the Corporation's outstanding repurchase rights with respect
to shares held by the Optionee at the time of such Involuntary Termination shall
immediately terminate, and the shares subject to those terminated repurchase
rights shall accordingly vest in full.

          G.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
limitation is not exceeded.  To the extent such dollar limitation is exceeded,
the accelerated portion of such option shall be exercisable as a Non-Statutory
Option under the Federal tax laws.

          H.   The outstanding options shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business


                                       -9-
<PAGE>

structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

   IV.    CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

    V.    STOCK APPRECIATION RIGHTS

          A.   The Plan Administrator shall have full power and authority to
grant to selected Optionees tandem stock appreciation rights and/or limited
stock appreciation rights.

          B.   The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

                 (i)     One or more Optionees may be granted the right,
     exercisable upon such terms as the Plan Administrator may establish,
     to elect between the exercise of the underlying option for shares of
     Common Stock and the surrender of that option in exchange for a
     distribution from the Corporation in an amount equal to the excess of
     (a) the Fair Market Value (on the option surrender date) of the number
     of shares in which the Optionee is at the time vested under the
     surrendered option (or surrendered portion thereof) over (b) the
     aggregate exercise price payable for such shares.

                (ii)     No such option surrender shall be effective unless
     it is approved by the Plan Administrator, either at the time of the
     actual option surrender or at any earlier time.  If the surrender is
     so approved, then the distribution to which the Optionee shall be
     entitled may be made in shares of Common Stock valued at Fair Market
     Value on the option surrender date, in cash, or partly in shares and
     partly in cash, as the Plan Administrator shall in its sole discretion
     deem appropriate.

               (iii)     If the surrender of an option is not approved by
     the Plan Administrator, then the Optionee shall retain whatever rights
     the Optionee had under the surrendered option (or surrendered portion
     thereof) on the option surrender date and may exercise such rights at
     any time prior to the LATER of (a) five (5) business days after the
     receipt of the rejection notice or (b) the last day on which the
     option is otherwise exercisable in


                                      -10-
<PAGE>

     accordance with the terms of the documents evidencing such option, but in
     no event may such rights be exercised more than ten (10) years after the
     option grant date.

          C.   The following terms shall govern the grant and exercise of
limited stock appreciation rights:

                 (i)     One or more Section 16 Insiders may be granted
     limited stock appreciation rights with respect to their outstanding
     options.

                (ii)     Upon the occurrence of a Hostile Take-Over, each
     individual holding one or more options with such a limited stock
     appreciation right shall have the unconditional right (exercisable for
     a thirty (30)-day period following such Hostile Take-Over) to
     surrender each such option to the Corporation, to the extent the
     option is at the time exercisable for vested shares of Common Stock.
     In return for the surrendered option, the Optionee shall receive a
     cash distribution from the Corporation in an amount equal to the
     excess of (A) the Take-Over Price of the shares of Common Stock which
     are at the time vested under each surrendered option (or surrendered
     portion thereof) over (B) the aggregate exercise price payable for
     such shares.  Such cash distribution shall be paid within five (5)
     days following the option surrender date.

               (iii)     Neither the approval of the Plan Administrator nor
     the consent of the Board shall be required in connection with such
     option surrender and cash distribution.

                (iv)     The balance of the option (if any) shall remain
     outstanding and exercisable in accordance with the documents
     evidencing such option.

                                ARTICLE THREE

                             STOCK ISSUANCE PROGRAM

    I.    STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.


                                      -11-
<PAGE>

          A.   PURCHASE PRICE.

               1.   The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

               2.   Subject to the provisions of Section I of Article Five,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                 (i)     cash or check made payable to the Corporation, or

                (ii)     past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   VESTING PROVISIONS.

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives.  The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

                 (i)     the Service period to be completed by the
     Participant or the performance objectives to be attained,

                (ii)     the number of installments in which the shares are
     to vest,

               (iii)     the interval or intervals (if any) which are to
     lapse between installments, and

                (iv)     the effect which death, Permanent Disability or
     other event designated by the Plan Administrator is to have upon the
     vesting schedule,

shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

               2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock


                                      -12-
<PAGE>

by reason of any stock dividend, stock split, recapitalization, combination of
shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration shall be
issued subject to (i) the same vesting requirements applicable to the
Participant's unvested shares of Common Stock and (ii) such escrow arrangements
as the Plan Administrator shall deem appropriate.

               3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested.  Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

               4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares.  To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

               5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares.  Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares as to which the waiver applies.  Such waiver may be effected at any
time, whether before or after the Participant's cessation of Service or the
attainment or non-attainment of the applicable performance objectives.

   II.    CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   All of the Corporation's outstanding repurchase/cancellation
rights under the Stock Issuance Program shall terminate automatically, and all
the shares of Common Stock subject to those terminated rights shall immediately
vest in full, in the event of any Corporate Transaction, except to the extent
(i) those repurchase/cancellation rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed in the
Stock Issuance Agreement.

          B.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance


                                      -13-
<PAGE>

Program, to provide that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest, in the event the Participant's Service should subsequently
terminate by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those repurchase/cancellation rights are assigned
to the successor corporation (or parent thereof).

          C.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control.

  III.    SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                                  ARTICLE FOUR

                     AUTOMATIC OPTION GRANT/ISSUANCE PROGRAM

    I.    OPTION TERMS

          A.   GRANT DATES.  On the date of each Annual Stockholders Meeting
held after the Effective Date, option grants shall be made to (i) each new
Eligible Director who is elected to the Board at that particular Annual Meeting
and (ii) each continuing Eligible Director who is elected to the Board at that
particular Annual Meeting.  Each automatic option grant shall be a Non-Statutory
Option.  Each Eligible Director shall be granted an option to purchase 15,000
shares of Common Stock at the Annual Meeting at which he or she is first elected
to the Board and an option to purchase 5,000 shares of Common Stock at each
Annual Meeting thereafter at which he or she is elected to the Board.  There
shall be no limit on the number of such automatic option grants any one Eligible
Director may receive over his or her period of Board service, and non-employee
Board members who have previously been in the employ of the Corporation (or any
Parent or Subsidiary) or who have otherwise received a stock option grant from
the Corporation prior to the Effective Date shall be eligible to receive one or
more such annual option grants over their period of continued Board service.

          B.   EXERCISE PRICE FOR OPTION SHARES.


                                      -14-
<PAGE>

               1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the date of
the Annual Stockholders Meeting with respect to which the option is granted.

               2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   OPTION TERM.  Each option shall have a term of ten (10) years
measured from the option grant date.

          D.   EXERCISE AND VESTING OF OPTIONS.  Each option shall be
exercisable only with respect to option shares with respect to which the
automatic option grant has become vested.  Provided that the non-employee
director continues to be a Member of the Board, the 15,000 share option grant
shall vest over four years in successive equal monthly installments from the
date of grant and the 5,000 share option grants shall vest at the end of each
additional year of Service completed by the optionee.  No portion of the
automatic option grant shall vest after the optionee has ceased to be a member
of the Board.

          E.   TERMINATION OF BOARD SERVICE.  The following provisions shall
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

                 (i)     The Optionee (or, in the event of Optionee's
     death, the personal representative of the Optionee's estate or the
     person or persons to whom the option is transferred pursuant to the
     Optionee's will or in accordance with the laws of descent and
     distribution) shall have a twelve (12)-month period following the date
     of such cessation of Board service in which to exercise each such
     option.

                (ii)     During the twelve (12)-month exercise period, the
     option may not be exercised in the aggregate for more than the number
     of vested shares of Common Stock for which the option is exercisable
     at the time of the Optionee's cessation of Board service.

               (iii)     Should the Optionee cease to serve as a Board
     member by reason of death or Permanent Disability, then all shares at
     the time subject to the option shall immediately vest so that such
     option may, during the twelve (12)-month exercise period following
     such cessation of Board service, be exercised for all or any portion
     of those shares as fully-vested shares of Common Stock.

                (iv)     In no event shall the option remain exercisable
     after the expiration of the option term.  Upon the expiration of the
     twelve


                                      -15-
<PAGE>

     (12)-month exercise period or (if earlier) upon the expiration of the
     option term, the option shall terminate and cease to be outstanding for any
     vested shares for which the option has not been exercised.  However, the
     option shall, immediately upon the Optionee's cessation of Board service
     for any reason other than death or Permanent Disability, terminate and
     cease to be outstanding to the extent the option is not otherwise at that
     time exercisable for vested shares.

   II.    CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Corporate Transaction, become fully
exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of those shares as fully-
vested shares of Common Stock.  Immediately following the consummation of the
Corporate Transaction, each automatic option grant shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          B.   In connection with any Change in Control, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Change in Control, become fully exercisable
for all of the shares of Common Stock at the time subject to such option and may
be exercised for all or any portion of those shares as fully-vested shares of
Common Stock.  Each such option shall remain exercisable for such fully-vested
option shares until the expiration or sooner termination of the option term or
the surrender of the option in connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding automatic option grants.  The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares.  Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation.  No approval or
consent of the Board or any Plan Administrator shall be required in connection
with such option surrender and cash distribution.

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be


                                      -16-
<PAGE>

made to the exercise price payable per share under each outstanding option,
PROVIDED the aggregate exercise price payable for such securities shall remain
the same.

          E.   The grant of options under the Automatic Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.


  III.    REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

                                  ARTICLE FIVE

                                  MISCELLANEOUS

    I.    FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

   II.    TAX WITHHOLDING

          A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

          B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant Program) with the right to use shares of Common Stock in
satisfaction of all or part of the Taxes incurred by such holders in connection
with the exercise of their options or the vesting of their


                                      -17-
<PAGE>

shares.  Such right may be provided to any such holder in either or both of the
following formats:

               STOCK WITHHOLDING:  The election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the Taxes
(not to exceed one hundred percent (100%)) designated by the holder.

               STOCK DELIVERY:  The election to deliver to the Corporation, at
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Taxes) with
an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

  III.    EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective immediately upon the Plan
Effective Date.  Options may be granted under the Discretionary Option Grant or
Automatic Option Grant Program at any time on or after the Plan Effective Date.
However, no options granted under the Plan may be exercised, and no shares shall
be issued under the Plan, until the Plan is approved by the Corporation's
stockholders.  If such stockholder approval is not obtained within twelve (12)
months after the Plan Effective Date, then all options previously granted under
this Plan shall terminate and cease to be outstanding, and no further options
shall be granted and no shares shall be issued under the Plan.

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further option grants or direct stock issuances shall be made under the
Predecessor Plan after the Section 12 Registration Date.   All options
outstanding under the Predecessor Plan on the Section 12 Registration Date shall
be incorporated into the Plan at that time and shall be treated as outstanding
options under the Plan.  However, each outstanding option so incorporated shall
continue to be governed solely by the terms of the documents evidencing such
option, and no provision of the Plan shall be deemed to affect or otherwise
modify the rights or obligations of the holders of such incorporated options
with respect to their acquisition of shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plan which do not otherwise contain such provisions.

          D.   The Plan shall terminate upon the EARLIEST of (i) the tenth
anniversary of the Plan Effective Date, (ii) the date on which all shares
available for issuance under the


                                      -18-
<PAGE>

Plan shall have been issued as fully-vested shares or (iii) the termination of
all outstanding options in connection with a Corporate Transaction.  Upon such
plan termination, all outstanding option grants and unvested stock issuances
shall thereafter continue to have force and effect in accordance with the
provisions of the documents evidencing such grants or issuances.

   IV.    AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
if so determined by the Board or pursuant to applicable laws or regulations.

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and shares of Common Stock may be issued under
the Stock Issuance Program that are in each instance in excess of the number of
shares then available for issuance under the Plan, provided any excess shares
actually issued under those programs shall be held in escrow until there is
obtained any required approval of an amendment sufficiently increasing the
number of shares of Common Stock available for issuance under the Plan.  If such
approval is not obtained within twelve (12) months after the date the first such
excess issuances are made, then (i) any unexercised options granted on the basis
of such excess shares shall terminate and cease to be outstanding and (ii) the
Corporation shall promptly refund to the Optionees and the Participants the
exercise or purchase price paid for any excess shares issued under the Plan and
held in escrow, together with interest (at the applicable Short Term Federal
Rate) for the period the shares were held in escrow, and such shares shall
thereupon be automatically cancelled and cease to be outstanding.

    V.    USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

   VI.    REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.


                                      -19-
<PAGE>

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

  VII.    NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                                STOCK OPTION AGREEMENT


RECITALS

    A.   The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or of the
board of directors of any Parent or Subsidiary and consultants and other
independent advisors who provide services to the Corporation (or any Parent or
Subsidiary).

    B.   Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

    C.   All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

         NOW, THEREFORE, it is hereby agreed as follows:

         1.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice.  The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

         2.   OPTION TERM.  This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5 or 6.

         3.   LIMITED TRANSFERABILITY.  If this option is designated an
Incentive Option in the Grant Notice, then this option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.  However, if this option is designated a
Non-Statutory Option in the Grant Notice, then this option may also be assigned
in whole or in part during Optionee's lifetime. The assigned portion shall be
exercisable only by the person or persons who acquire a proprietary interest in
the option pursuant to such assignment.  The terms applicable to the assigned
portion shall be the same as those in effect for this option immediately prior
to such assignment and shall be set forth in such documents issued to the
assignee as the Plan Administrator may deem appropriate.

         4.   DATES OF EXERCISE.  This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice.  As
the option becomes

<PAGE>

exercisable for such installments, those installments shall accumulate and the
option shall remain exercisable for the accumulated installments until the
Expiration Date or sooner termination of the option term under Paragraph 5 or 6.

         5.   CESSATION OF SERVICE.  The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable:

                (i)     Should Optionee cease to remain in Service for any
    reason (other than death, Permanent Disability or Misconduct) while
    this option is outstanding, then Optionee shall have a period of three
    (3) months (commencing with the date of such cessation of Service)
    during which to exercise this option, but in no event shall this
    option be exercisable at any time after the Expiration Date.

               (ii)     Should Optionee die while this option is
    outstanding, then the personal representative of Optionee's estate or
    the person or persons to whom the option is transferred pursuant to
    Optionee's will or in accordance with the laws of descent and
    distribution shall have the right to exercise this option.  Such right
    shall lapse, and this option shall cease to be outstanding, upon the
    EARLIER of (A) the expiration of the twelve (12)- month period
    measured from the date of Optionee's death or (B) the Expiration Date.

              (iii)     Should Optionee cease Service by reason of
    Permanent Disability while this option is outstanding, then Optionee
    shall have a period of twelve (12) months (commencing with the date of
    such cessation of Service) during which to exercise this option.  In
    no event shall this option be exercisable at any time after the
    Expiration Date.

               (iv)     During the limited period of post-Service
    exercisability, this option may not be exercised in the aggregate for
    more than the number of vested Option Shares for which the option is
    exercisable at the time of Optionee's cessation of Service.  Upon the
    expiration of such limited exercise period or (if earlier) upon the
    Expiration Date, this option shall terminate and cease to be
    outstanding for any vested Option Shares for which the option has not
    been exercised.  However, this option shall, immediately upon
    Optionee's cessation of Service for any reason, terminate and cease to
    be outstanding with respect to any Option Shares in which Optionee is
    not otherwise at that time vested or for which this option is not
    otherwise at that time exercisable.


                                          2.


<PAGE>

                   (v)  Should Optionee's Service be terminated for
    Misconduct, then this option shall terminate immediately and cease to
    remain outstanding.

         6.   SPECIAL ACCELERATION OF OPTION.

              (a)  This option, to the extent outstanding at the time of a
Corporate Transaction but not otherwise fully exercisable, shall automatically
accelerate so that this option shall, immediately prior to the effective date of
the Corporate Transaction, become exercisable for all of the Option Shares at
the time subject to this option and may be exercised for any or all of those
Option Shares as fully-vested shares of Common Stock.  No such acceleration of
this option, however, shall occur if and to the extent: (i) this option is, in
connection with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof) or (ii) this option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
Option Shares at the time of the Corporate Transaction (the excess of the Fair
Market Value of those Option Shares over the aggregate Exercise Price payable
for such shares) and provides for subsequent pay-out in accordance with the
option exercise/vesting schedule set forth in the Grant Notice.  The
determination of option comparability under clause (i) shall be made by the Plan
Administrator, and such determination shall be final, binding and conclusive.

              (b)  Immediately following the Corporate Transaction, this option
shall terminate and cease to be outstanding, except  to the extent assumed by
the successor corporation (or parent thereof) in connection with the Corporate
Transaction.

              (c)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, PROVIDED the aggregate Exercise Price shall remain the same.

              (d)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

         7.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be


                                          3.


<PAGE>

made to (i) the total number and/or class of securities subject to this option
and (ii) the Exercise Price in order to reflect such change and thereby preclude
a dilution or enlargement of benefits hereunder.

         8.   STOCKHOLDER RIGHTS.  The holder of this option shall not have any
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

         9.   MANNER OF EXERCISING OPTION.

              (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                     (i)     Execute and deliver to the Corporation a
    Notice of Exercise for the Option Shares for which the option is
    exercised.

                    (ii)     Pay the aggregate Exercise Price for the
    purchased shares in one or more of the following forms:

                        (A)  cash or check made payable to the
         Corporation;

                        (B)  a promissory note payable to the Corporation,
         but only to the extent authorized by the Plan Administrator in
         accordance with Paragraph 13;

                        (C)  shares of Common Stock held by Optionee (or
         any other person or persons exercising the option) for the
         requisite period necessary to avoid a charge to the Corporation's
         earnings for financial reporting purposes and valued at Fair
         Market Value on the Exercise Date; or

                        (D)  to the extent the option is exercised for
         vested Option Shares, through a special sale and remittance
         procedure pursuant to which Optionee (or any other person or
         persons exercising the option) shall concurrently provide
         irrevocable written instructions (I) to a Corporation-designated
         brokerage firm to effect the immediate sale of the purchased
         shares and remit to the Corporation, out of the sale proceeds
         available on the settlement date, sufficient funds to cover the

         shares directly to such brokerage firm in order to complete the sale
         transaction.

              Except to the extent the sale and remittance procedure is
         utilized in connection with the option exercise, payment of the
         Exercise Price must accompany the Notice of Exercise delivered to
         the Corporation in connection with the option exercise.

                   (iii)     Furnish to the Corporation appropriate
    documentation that the person or persons exercising the option (if
    other than Optionee) have the right to exercise this option.

                    (iv)     Make appropriate arrangements with the
    Corporation (or Parent or Subsidiary employing or retaining Optionee)
    for the satisfaction of all Federal, state and local income and

    exercise.

              (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.

              (c)  In no event may this option be exercised for any fractional
shares.

         10.  COMPLIANCE WITH LAWS AND REGULATIONS.

              (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

              (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.

         11.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the
benefit of, and be binding upon, the Corporation and its successors and assigns
and Optionee, Optionee's assigns and the legal representatives, heirs and
legatees of Optionee's estate.


                                          5.


<PAGE>

         12.  NOTICES.  Any notice required to be given or delivered to the
Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices.  Any notice required to
be given or delivered to Optionee shall be in writing and addressed to Optionee
at the address indicated below Optionee's signature line on the Grant Notice.
All notices shall be deemed effective upon personal delivery or upon deposit in
the U.S. mail, postage prepaid and properly addressed to the party to be
notified.

         13.  FINANCING.  The Plan Administrator may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a full-recourse
promissory note payable to the Corporation.  The terms of any such promissory
note (including the interest rate, the requirements for collateral and the terms
of repayment) shall be established by the Plan Administrator in its sole
discretion.

         14.  CONSTRUCTION.  This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan.  All decisions of the Plan Administrator with
respect to any question or issue arising under the Plan or this Agreement shall
be conclusive and binding on all persons having an interest in this option.

         15.  GOVERNING LAW.  The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of California
without resort to that State's conflict-of-laws rules.

         16.  EXCESS SHARES.  If the Option Shares covered by this Agreement
exceed, as of the Grant Date, the number of shares of Common Stock which may
without stockholder approval be issued under the Plan, then this option shall be
void with respect to those excess shares, unless stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock issuable
under the Plan is obtained in accordance with the provisions of the Plan.

         17.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION.  In the event
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:

              -    This option shall cease to qualify for favorable tax
    treatment as an Incentive Option if (and to the extent) this option is
    exercised for one or more Option Shares: (A) more than three (3)
    months after the date Optionee ceases to be an Employee for any reason
    other than death or Permanent Disability or (B) more than twelve (12)
    months after the date Optionee ceases to be an Employee by reason of
    Permanent Disability.


                                          6.


<PAGE>

              -    No installment under this option shall qualify for
    favorable tax treatment as an Incentive Option if (and to the extent)
    the aggregate Fair Market Value (determined at the Grant Date) of the
    Common Stock for which such installment first becomes exercisable
    hereunder would, when added to the aggregate value (determined as of
    the respective date or dates of grant) of the Common Stock or other
    securities for which this option or any other Incentive Options
    granted to Optionee prior to the Grant Date (whether under the Plan or
    any other option plan of the Corporation or any Parent or Subsidiary)
    first become exercisable during the same calendar year, exceed One
    Hundred Thousand Dollars ($100,000) in the aggregate.  Should such One
    Hundred Thousand Dollar ($100,000) limitation be exceeded in any
    calendar year, this option shall nevertheless become exercisable for
    the excess shares in such calendar year as a Non-Statutory Option.

              -    Should the exercisability of this option be accelerated
    upon a Corporate Transaction, then this option shall qualify for
    favorable tax treatment as an Incentive Option only to the extent the
    aggregate Fair Market Value (determined at the Grant Date) of the
    Common Stock for which this option first becomes exercisable in the
    calendar year in which the Corporate Transaction occurs does not, when
    added to the aggregate value (determined as of the respective date or
    dates of grant) of the Common Stock or other securities for which this
    option or one or more other Incentive Options granted to Optionee
    prior to the Grant Date (whether under the Plan or any other option
    plan of the Corporation or any Parent or Subsidiary) first become
    exercisable during the same calendar year, exceed One Hundred Thousand
    Dollars ($100,000) in the aggregate.  Should the applicable One
    Hundred Thousand Dollar ($100,000) limitation be exceeded in the
    calendar year of such Corporate Transaction, the option may
    nevertheless be exercised for the excess shares in such calendar year
    as a Non-Statutory Option.

              -    Should Optionee hold, in addition to this option, one
    or more other options to purchase Common Stock which become
    exercisable for the first time in the same calendar year as this
    option, then the foregoing limitations on the exercisability of such
    options as Incentive Options shall be applied on the basis of the
    order in which such options are granted.

         18.  LEAVE OF ABSENCE.  The following provisions shall apply upon the
Optionee's commencement of an authorized leave of absence:

              (a)  The exercise schedule in effect under the Grant Notice
    shall be frozen as of the first day of the authorized leave, and this
    option shall not become exercisable for any additional installments of
    the Option Shares during the period Optionee remains on such leave.


                                          7.


<PAGE>

              (b)  Should Optionee resume active Employee status within
    sixty (60) days after the start date of the authorized leave, Optionee
    shall, for purposes of the exercise schedule set forth in the Grant
    Notice, receive Service credit for the entire period of such leave.
    If Optionee does not resume active Employee status within such sixty
    (60)-day period, then no Service credit shall be given for the period
    of such leave.

              (c)  If the option is designated as an Incentive Option in
    the Grant Notice, then the following additional provision shall apply:

                   -    If the leave of absence continues for more than
         ninety (90) days, then this option shall automatically convert to
         a Non-Statutory Option under the Federal tax laws on the
         ninety-first (91st) day of such leave, unless the Optionee's
         reemployment rights are guaranteed by statute or by written
         agreement.  Following any such conversion of the option, all
         subsequent exercises of such option, whether effected before or
         after Optionee's return to active Employee status, shall result
         in an immediate taxable event, and the Corporation shall be
         required to collect from Optionee the Federal, state and local
         income and employment withholding taxes applicable to such
         exercise.

              (d)  In no event shall this option become exercisable for
    any additional Option Shares or otherwise remain outstanding if
    Optionee does not resume Employee status prior to the Expiration Date
    of the option term.

                                          8.

<PAGE>

                            AS AMENDED MARCH 3, 1997

                        VISTA MEDICAL TECHNOLOGIES, INC.


                      1997 STOCK OPTION/STOCK ISSUANCE PLAN


                                   ARTICLE ONE

                               GENERAL PROVISIONS

    I.    PURPOSE OF THE PLAN

          This 1997 Stock Option/Stock Issuance Plan is intended to promote the
interests of Vista Medical Technologies, Inc., a Delaware corporation, by
providing eligible persons with the opportunity to acquire a proprietary
interest, or otherwise increase their proprietary interest, in the Corporation
as an incentive for them to remain in the service of the Corporation.

          Capitalized terms shall have the meanings assigned to such terms in
the attached Appendix.

   II.    STRUCTURE OF THE PLAN

          A.   The Plan shall be divided into three separate equity programs:

               -    the Discretionary Option Grant Program under which eligible
persons may, at the discretion of the Plan Administrator, be granted options to
purchase shares of Common Stock,

               -    the Stock Issuance Program under which eligible persons may,
at the discretion of the Plan Administrator, be issued shares of Common Stock
directly, either through the immediate purchase of such shares or as a bonus for
services rendered the Corporation (or any Parent or Subsidiary), and

               -    the Automatic Option Grant Program under which eligible non-
employee Board members shall automatically receive option grants at periodic
intervals to purchase shares of Common Stock.

          B.   The provisions of Articles One and Five shall apply to all equity
programs under the Plan and shall govern the interests of all persons under the
Plan.

  III.    ADMINISTRATION OF THE PLAN

<PAGE>

          A.   Prior to the Section 12 Registration Date, the Discretionary
Option Grant and Stock Issuance Programs shall be administered by the Board.
Beginning with the Section 12 Registration Date, the Primary Committee shall
have sole and exclusive authority to administer the Discretionary Option Grant
and Stock Issuance Programs with respect to Section 16 Insiders.

          B.   Administration of the Discretionary Option Grant and Stock
Issuance Programs with respect to all other persons eligible to participate in
those programs may, at the Board's discretion, be vested in the Primary
Committee or a Secondary Committee, or the Board may retain the power to
administer those programs with respect to all such persons.  The members of the
Secondary Committee may be Board members who are Employees eligible to receive
discretionary option grants or direct stock issuances under the Plan or any
other stock option, stock appreciation, stock bonus or other stock plan of the
Corporation (or any Parent or Subsidiary).

          C.   Members of the Primary Committee or any Secondary Committee shall
serve for such period of time as the Board may determine and may be removed by
the Board at any time.  The Board may also at any time terminate the functions
of any Secondary Committee and reassume all powers and authority previously
delegated to such committee.

          D.   Each Plan Administrator shall, within the scope of its
administrative functions under the Plan, have full power and authority (subject
to the provisions of the Plan) to establish such rules and regulations as it may
deem appropriate for proper administration of the Discretionary Option Grant and
Stock Issuance Programs and to make such determinations under, and issue such
interpretations of, the provisions of such programs and any outstanding options
or stock issuances thereunder as it may deem necessary or advisable.  Decisions
of the Plan Administrator within the scope of its administrative functions under
the Plan shall be final and binding on all parties who have an interest in the
Discretionary Option Grant and Stock Issuance Programs under its jurisdiction or
any option or stock issuance thereunder.

          E.   Service on the Primary Committee or the Secondary Committee shall
constitute service as a Board member, and members of each such committee shall
accordingly be entitled to full indemnification and reimbursement as Board
members for their service on such committee.  No member of the Primary Committee
or the Secondary Committee shall be liable for any act or omission made in good
faith with respect to the Plan or any option grants or stock issuances under the
Plan.

          F.   Administration of the Automatic Option Grant Program shall be
self-executing in accordance with the terms of that program, and no Plan
Administrator shall exercise any discretionary functions with respect to any
option grants or stock issuances made under this program.

   IV.    ELIGIBILITY


                                       -2-
<PAGE>

          A.   The persons eligible to participate in the Discretionary Option
Grant and Stock Issuance Programs are as follows:

                 (i)     Employees,

                (ii)     non-employee members of the Board or the board of
     directors of any Parent or Subsidiary, and

               (iii)     consultants and other independent advisors who
     provide services to the Corporation (or any Parent or Subsidiary).

          B.   Each Plan Administrator shall, within the scope of its
administrative jurisdiction under the Plan, have full authority to determine,
(i) with respect to the option grants under the Discretionary Option Grant
Program, which eligible persons are to receive option grants, the time or times
when such option grants are to be made, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive Option
or a Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding and (ii) with
respect to stock issuances under the Stock Issuance Program, which eligible
persons are to receive stock issuances, the time or times when such issuances
are to be made, the number of shares to be issued to each Participant, the
vesting schedule (if any) applicable to the issued shares and the consideration
for such shares.

          C.   The Plan Administrator shall have the absolute discretion either
to grant options in accordance with the Discretionary Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

          D.   The individuals who shall be eligible to participate in the
Automatic Option Grant Program shall be limited to non-employee Board members
who are elected or appointed to the Board after the Effective Date.  A non-
employee Board member who has previously been in the employ of the Corporation
(or any Parent or Subsidiary) shall not be eligible to receive an option grant
under the Automatic Option Grant Program at the time he or she first becomes a
non-employee Board member, but shall be eligible to receive periodic option
grants under the Automatic Option Grant Program while he or she continues to
serve as a non-employee Board member.

    V.    STOCK SUBJECT TO THE PLAN

          A.   The stock issuable under the Plan shall be shares of authorized
but unissued or reacquired Common Stock, including shares repurchased by the
Corporation on the open market.  The maximum number of shares of Common Stock
initially reserved for issuance over the term of the Plan shall not exceed
2,820,000 shares.


                                       -3-
<PAGE>

          B.   No one person participating in the Plan may receive options,
separately exercisable stock appreciation rights and direct stock issuances for
more than 50,000 shares of Common Stock in the aggregate per calendar year,
beginning with the 1997 calendar year.

          C.   Shares of Common Stock subject to outstanding options (including
options incorporated into this Plan from the Predecessor Plan) shall be
available for subsequent issuance under the Plan to the extent those options
expire or terminate for any reason prior to exercise in full.  Unvested shares
issued under the Plan and subsequently cancelled or repurchased by the
Corporation, at the original issue price paid per share, pursuant to the
Corporation's repurchase rights under the Plan shall be added back to the number
of shares of Common Stock reserved for issuance under the Plan and shall
accordingly be available for reissuance through one or more subsequent option
grants or direct stock issuances under the Plan.  However, should the exercise
price of an option under the Plan be paid with shares of Common Stock or should
shares of Common Stock otherwise issuable under the Plan be withheld by the
Corporation in satisfaction of the withholding taxes incurred in connection with
the exercise of an option or the vesting of a stock issuance under the Plan,
then the number of shares of Common Stock available for issuance under the Plan
shall be reduced by the gross number of shares for which the option is exercised
or which vest under the stock issuance, and not by the net number of shares of
Common Stock issued to the holder of such option or stock issuance.
Notwithstanding the above, no additional adjustment shall be made to any shares
or class of shares with respect to any transaction occurring prior to the
completion of an offering of shares of the Common Stock of the Company to the
public pursuant to an effective registration statement.

          D.   If any change is made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and/or class of securities issuable under the
Plan, (ii) the number and/or class of securities for which any one person may be
granted stock options, separately exercisable stock appreciation rights and
direct stock issuances under this Plan per calendar year, (iii) the number
and/or class of securities for which grants are subsequently to be made under
the Automatic Option Grant Program to new and continuing non-employee Board
members, (iv) the number and/or class of securities and the exercise price per
share in effect under each outstanding option under the Plan and (v) the number
and/or class of securities and price per share in effect under each outstanding
option incorporated into this Plan from the Predecessor Plan.  Such adjustments
to the outstanding options are to be effected in a manner which shall preclude
the enlargement or dilution of rights and benefits under such options. The
adjustments determined by the Plan Administrator shall be final, binding and
conclusive.

<PAGE>

    I.    OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; PROVIDED, however, that each such document
shall comply with the terms specified below.  Each document evidencing an
Incentive Option shall, in addition, be subject to the provisions of the Plan
applicable to such options.

          A.   EXERCISE PRICE.

               1.   The exercise price per share shall be fixed by the Plan
Administrator but shall not be less than eighty-five percent (85%) of the Fair
Market Value per share of Common Stock on the option grant date, provided that
the Plan Administrator may fix the exercise price at less than 85% if the
optionee, at the time of the option grant, shall have made a payment to the
Company (including payment made by means of a salary reduction) equal to the
excess of the Fair Market Value of the Common Stock on the option grant date
over such exercise price.

               2.   The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Five and the documents evidencing the option, be payable in one or more
of the forms specified below:

                 (i)     cash or check made payable to the Corporation,

                (ii)     shares of Common Stock held for the requisite
     period necessary to avoid a charge to the Corporation's earnings for
     financial reporting purposes and valued at Fair Market Value on the
     Exercise Date, or

               (iii)     to the extent the option is exercised for vested
     shares, through a special sale and remittance procedure pursuant to
     which the Optionee shall concurrently provide irrevocable written
     instructions to (a) a Corporation-designated brokerage firm to effect
     the immediate sale of the purchased shares and remit to the
     Corporation, out of the sale proceeds available on the settlement
     date, sufficient funds to cover the aggregate exercise price payable
     for the purchased shares plus all applicable Federal, state and local
     income and employment taxes required to be withheld by the Corporation
     by reason of such exercise and (b) the Corporation to deliver the
     certificates for the purchased shares directly to such brokerage firm
     in order to complete the sale.

          Except to the extent such sale and remittance procedure is utilized,
payment of the exercise price for the purchased shares must be made on the
Exercise Date.

          B.   EXERCISE AND TERM OF OPTIONS.  Each option shall be exercisable
at such time or times, during such period and for such number of shares as shall
be determined by the Plan Administrator and set forth in the documents
evidencing the option.  However, no


                                       -5-
<PAGE>

option shall have a term in excess of ten (10) years measured from the option
grant date.

          C.   EFFECT OF TERMINATION OF SERVICE.

               1.   The following provisions shall govern the exercise of any
options held by the Optionee at the time of cessation of Service or death:

                 (i)     Any option outstanding at the time of the
     Optionee's cessation of Service for any reason shall remain
     exercisable for such period of time thereafter as shall be determined
     by the Plan Administrator and set forth in the documents evidencing
     the option, but no such option shall be exercisable after the
     expiration of the option term.

                (ii)     Any option exercisable in whole or in part by the
     Optionee at the time of death may be subsequently exercised by the
     personal representative of the Optionee's estate or by the person or
     persons to whom the option is transferred pursuant to the Optionee's
     will or in accordance with the laws of descent and distribution.

               (iii)     Should the Optionee's Service be terminated for
     Misconduct, then all outstanding options held by the Optionee shall
     terminate immediately and cease to be outstanding.

                (iv)     During the applicable post-Service exercise
     period, the option may not be exercised in the aggregate for more than
     the number of vested shares for which the option is exercisable on the
     date of the Optionee's cessation of Service.  Upon the expiration of
     the applicable exercise period or (if earlier) upon the expiration of
     the option term, the option shall terminate and cease to be
     outstanding for any vested shares for which the option has not been
     exercised.  However, the option shall, immediately upon the Optionee's
     cessation of Service, terminate and cease to be outstanding to the
     extent the option is not otherwise at that time exercisable for vested
     shares.

               2.   The Plan Administrator shall have complete discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                (i)      extend the period of time for which the option is
     to remain exercisable following the Optionee's cessation of Service
     from the limited exercise period otherwise in effect for that option
     to such greater period of time as the Plan Administrator shall deem
     appropriate, but in no event beyond the expiration of the option term,
     and/or


                                       -6-
<PAGE>

                (ii)     permit the option to be exercised, during the
     applicable post-Service exercise period, not only with respect to the
     number of vested shares of Common Stock for which such option is
     exercisable at the time of the Optionee's cessation of Service but
     also with respect to one or more additional installments in which the
     Optionee would have vested had the Optionee continued in Service.

          D.   STOCKHOLDER RIGHTS.  The holder of an option shall have no
stockholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become a
holder of record of the purchased shares.

          E.   REPURCHASE RIGHTS.  The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock.  Should the Optionee cease Service while holding such unvested shares,
the Corporation shall have the right to repurchase, at the exercise price paid
per share, any or all of those unvested shares.  The terms upon which such
repurchase right shall be exercisable (including the period and procedure for
exercise and the appropriate vesting schedule for the purchased shares) shall be
established by the Plan Administrator and set forth in the document evidencing
such repurchase right.

          F.   LIMITED TRANSFERABILITY OF OPTIONS.  During the lifetime of the
Optionee, Incentive Options shall be exercisable only by the Optionee and shall
not be assignable or transferable other than by will or by the laws of descent
and distribution following the Optionee's death.  However, a Non-Statutory
Option may be assigned in whole or in part during the Optionee's lifetime.  The
assigned portion may only be exercised by the person or persons who acquire a
proprietary interest in the option pursuant to the assignment. The terms
applicable to the assigned portion shall be the same as those in effect for the
option immediately prior to such assignment and shall be set forth in such
documents issued to the assignee as the Plan Administrator may deem appropriate.

   II.    INCENTIVE OPTIONS

          The terms specified below shall be applicable to all Incentive
Options.  Except as modified by the provisions of this Section II, all the
provisions of Articles One, Two and Five shall be applicable to Incentive
Options.  Options which are specifically designated as Non-Statutory Options
when issued under the Plan shall NOT be subject to the terms of this Section II.

          A.   ELIGIBILITY.  Incentive Options may only be granted to Employees.


          B.   EXERCISE PRICE.  The exercise price per share shall not be less
than one hundred percent (100%) of the Fair Market Value per share of Common
Stock on the option grant date.


                                       -7-
<PAGE>

          C.   DOLLAR LIMITATION.  The aggregate Fair Market Value of the shares
of Common Stock (determined as of the respective date or dates of grant) for
which one or more options granted to any Employee under the Plan (or any other
option plan of the Corporation or any Parent or Subsidiary) may for the first
time become exercisable as Incentive Options during any one calendar year shall
not exceed the sum of One Hundred Thousand Dollars ($100,000).  To the extent
the Employee holds two (2) or more such options which become exercisable for the
first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

          D.   10% STOCKHOLDER.  If any Employee to whom an Incentive Option is
granted is a 10% Stockholder, then the exercise price per share shall not be
less than one hundred ten percent (110%) of the Fair Market Value per share of
Common Stock on the option grant date, and the option term shall not exceed five
(5) years measured from the option grant date.

  III.    CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   In the event of any Corporate Transaction, each outstanding
option shall automatically accelerate so that each such option shall,
immediately prior to the effective date of the Corporate Transaction, become
fully exercisable with respect to the total number of shares of Common Stock at
the time subject to such option and may be exercised for any or all of those
shares as fully-vested shares of Common Stock.  However, an outstanding option
shall not so accelerate if and to the extent:  (i) such option is, in connection
with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof), (ii) such option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
option shares at the time of the Corporate Transaction and provides for
subsequent payout in accordance with the same vesting schedule applicable to
those option shares or (iii) the acceleration of such option is subject to other
limitations imposed by the Plan Administrator at the time of the option grant.
The determination of option comparability under clause (i) above shall be made
by the Plan Administrator, and its determination shall be final, binding and
conclusive.

          B.   All outstanding repurchase rights shall terminate automatically,
and the shares of Common Stock subject to those terminated rights shall
immediately vest in full, in the event of any Corporate Transaction, except to
the extent: (i) those repurchase rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed by the
Plan Administrator at the time the repurchase right is issued.
          C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).


                                       -8-
<PAGE>

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments to reflect such Corporate Transaction shall also be made
to (i) the exercise price payable per share under each outstanding option,
PROVIDED the aggregate exercise price payable for such securities shall remain
the same, (ii) the maximum number and/or class of securities available for
issuance over the remaining term of the Plan and (iii) the maximum number and/or
class of securities for which any one person may be granted stock options,
separately exercisable stock appreciation rights and direct stock issuances
under the Plan per calendar year.

          E.   The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionee's Service subsequently
terminates by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those options are assumed or replaced and do not
otherwise accelerate.  Any options so accelerated shall remain exercisable for
fully-vested shares until the EARLIER of (i) the expiration of the option term
or (ii) the expiration of the one (1)-year period measured from the effective
date of the Involuntary Termination.  In addition, the Plan Administrator may
provide that one or more of the Corporation's outstanding repurchase rights with
respect to shares held by the Optionee at the time of such Involuntary
Termination shall immediately terminate, and the shares subject to those
terminated repurchase rights shall accordingly vest in full.

          F.   The Plan Administrator shall have full power and authority to
grant options under the Discretionary Option Grant Program which will
automatically accelerate in the event the Optionee's Service subsequently
terminates by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any Change
in Control.  Each option so accelerated shall remain exercisable for fully-
vested shares until the EARLIER of (i) the expiration of the option term or (ii)
the expiration of the one (1)-year period measured from the effective date of
the Involuntary Termination.  In addition, the Plan Administrator may provide
that one or more of the Corporation's outstanding repurchase rights with respect
to shares held by the Optionee at the time of such Involuntary Termination shall
immediately terminate, and the shares subject to those terminated repurchase
rights shall accordingly vest in full.

          G.   The portion of any Incentive Option accelerated in connection
with a Corporate Transaction or Change in Control shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand Dollar
limitation is not exceeded.  To the extent such dollar limitation is exceeded,
the accelerated portion of such option shall be exercisable as a Non-Statutory
Option under the Federal tax laws.

          H.   The outstanding options shall in no way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business


                                       -9-
<PAGE>

structure or to merge, consolidate, dissolve, liquidate or sell or transfer all
or any part of its business or assets.

   IV.    CANCELLATION AND REGRANT OF OPTIONS

          The Plan Administrator shall have the authority to effect, at any time
and from time to time, with the consent of the affected option holders, the
cancellation of any or all outstanding options under the Discretionary Option
Grant Program (including outstanding options incorporated from the Predecessor
Plan) and to grant in substitution new options covering the same or different
number of shares of Common Stock but with an exercise price per share based on
the Fair Market Value per share of Common Stock on the new grant date.

    V.    STOCK APPRECIATION RIGHTS

          A.   The Plan Administrator shall have full power and authority to
grant to selected Optionees tandem stock appreciation rights and/or limited
stock appreciation rights.

          B.   The following terms shall govern the grant and exercise of tandem
stock appreciation rights:

                 (i)     One or more Optionees may be granted the right,
     exercisable upon such terms as the Plan Administrator may establish,
     to elect between the exercise of the underlying option for shares of
     Common Stock and the surrender of that option in exchange for a
     distribution from the Corporation in an amount equal to the excess of
     (a) the Fair Market Value (on the option surrender date) of the number
     of shares in which the Optionee is at the time vested under the
     surrendered option (or surrendered portion thereof) over (b) the
     aggregate exercise price payable for such shares.

                (ii)     No such option surrender shall be effective unless
     it is approved by the Plan Administrator, either at the time of the
     actual option surrender or at any earlier time.  If the surrender is
     so approved, then the distribution to which the Optionee shall be
     entitled may be made in shares of Common Stock valued at Fair Market
     Value on the option surrender date, in cash, or partly in shares and
     partly in cash, as the Plan Administrator shall in its sole discretion
     deem appropriate.

               (iii)     If the surrender of an option is not approved by
     the Plan Administrator, then the Optionee shall retain whatever rights
     the Optionee had under the surrendered option (or surrendered portion
     thereof) on the option surrender date and may exercise such rights at
     any time prior to the LATER of (a) five (5) business days after the
     receipt of the rejection notice or (b) the last day on which the
     option is otherwise exercisable in


                                      -10-
<PAGE>

     accordance with the terms of the documents evidencing such option, but in
     no event may such rights be exercised more than ten (10) years after the
     option grant date.

          C.   The following terms shall govern the grant and exercise of
limited stock appreciation rights:

                 (i)     One or more Section 16 Insiders may be granted
     limited stock appreciation rights with respect to their outstanding
     options.

                (ii)     Upon the occurrence of a Hostile Take-Over, each
     individual holding one or more options with such a limited stock
     appreciation right shall have the unconditional right (exercisable for
     a thirty (30)-day period following such Hostile Take-Over) to
     surrender each such option to the Corporation, to the extent the
     option is at the time exercisable for vested shares of Common Stock.
     In return for the surrendered option, the Optionee shall receive a
     cash distribution from the Corporation in an amount equal to the
     excess of (A) the Take-Over Price of the shares of Common Stock which
     are at the time vested under each surrendered option (or surrendered
     portion thereof) over (B) the aggregate exercise price payable for
     such shares.  Such cash distribution shall be paid within five (5)
     days following the option surrender date.

               (iii)     Neither the approval of the Plan Administrator nor
     the consent of the Board shall be required in connection with such
     option surrender and cash distribution.

                (iv)     The balance of the option (if any) shall remain
     outstanding and exercisable in accordance with the documents
     evidencing such option.

                                ARTICLE THREE

                             STOCK ISSUANCE PROGRAM

    I.    STOCK ISSUANCE TERMS

          Shares of Common Stock may be issued under the Stock Issuance Program
through direct and immediate issuances without any intervening option grants.
Each such stock issuance shall be evidenced by a Stock Issuance Agreement which
complies with the terms specified below.


                                      -11-
<PAGE>

          A.   PURCHASE PRICE.

               1.   The purchase price per share shall be fixed by the Plan
Administrator, but shall not be less than one hundred percent (100%) of the Fair
Market Value per share of Common Stock on the issuance date.

               2.   Subject to the provisions of Section I of Article Five,
shares of Common Stock may be issued under the Stock Issuance Program for any of
the following items of consideration which the Plan Administrator may deem
appropriate in each individual instance:

                 (i)     cash or check made payable to the Corporation, or

                (ii)     past services rendered to the Corporation (or any
     Parent or Subsidiary).

          B.   VESTING PROVISIONS.

               1.   Shares of Common Stock issued under the Stock Issuance
Program may, in the discretion of the Plan Administrator, be fully and
immediately vested upon issuance or may vest in one or more installments over
the Participant's period of Service or upon attainment of specified performance
objectives.  The elements of the vesting schedule applicable to any unvested
shares of Common Stock issued under the Stock Issuance Program, namely:

                 (i)     the Service period to be completed by the
     Participant or the performance objectives to be attained,

                (ii)     the number of installments in which the shares are
     to vest,

               (iii)     the interval or intervals (if any) which are to
     lapse between installments, and

                (iv)     the effect which death, Permanent Disability or
     other event designated by the Plan Administrator is to have upon the
     vesting schedule,

shall be determined by the Plan Administrator and incorporated into the Stock
Issuance Agreement.

               2.   Any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend) which the
Participant may have the right to receive with respect to the Participant's
unvested shares of Common Stock


                                      -12-
<PAGE>

by reason of any stock dividend, stock split, recapitalization, combination of
shares, exchange of shares or other change affecting the outstanding Common
Stock as a class without the Corporation's receipt of consideration shall be
issued subject to (i) the same vesting requirements applicable to the
Participant's unvested shares of Common Stock and (ii) such escrow arrangements
as the Plan Administrator shall deem appropriate.

               3.   The Participant shall have full stockholder rights with
respect to any shares of Common Stock issued to the Participant under the Stock
Issuance Program, whether or not the Participant's interest in those shares is
vested.  Accordingly, the Participant shall have the right to vote such shares
and to receive any regular cash dividends paid on such shares.

               4.   Should the Participant cease to remain in Service while
holding one or more unvested shares of Common Stock issued under the Stock
Issuance Program or should the performance objectives not be attained with
respect to one or more such unvested shares of Common Stock, then those shares
shall be immediately surrendered to the Corporation for cancellation, and the
Participant shall have no further stockholder rights with respect to those
shares.  To the extent the surrendered shares were previously issued to the
Participant for consideration paid in cash or cash equivalent (including the
Participant's purchase-money indebtedness), the Corporation shall repay to the
Participant the cash consideration paid for the surrendered shares and shall
cancel the unpaid principal balance of any outstanding purchase-money note of
the Participant attributable to the surrendered shares.

               5.   The Plan Administrator may in its discretion waive the
surrender and cancellation of one or more unvested shares of Common Stock which
would otherwise occur upon the cessation of the Participant's Service or the
non-attainment of the performance objectives applicable to those shares.  Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares as to which the waiver applies.  Such waiver may be effected at any
time, whether before or after the Participant's cessation of Service or the
attainment or non-attainment of the applicable performance objectives.

   II.    CORPORATE TRANSACTION/CHANGE IN CONTROL

          A.   All of the Corporation's outstanding repurchase/cancellation
rights under the Stock Issuance Program shall terminate automatically, and all
the shares of Common Stock subject to those terminated rights shall immediately
vest in full, in the event of any Corporate Transaction, except to the extent
(i) those repurchase/cancellation rights are to be assigned to the successor
corporation (or parent thereof) in connection with such Corporate Transaction or
(ii) such accelerated vesting is precluded by other limitations imposed in the
Stock Issuance Agreement.

          B.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance


                                      -13-
<PAGE>

Program, to provide that those rights shall automatically terminate in whole or
in part, and the shares of Common Stock subject to those terminated rights shall
immediately vest, in the event the Participant's Service should subsequently
terminate by reason of an Involuntary Termination within a designated period
(not to exceed eighteen (18) months) following the effective date of any
Corporate Transaction in which those repurchase/cancellation rights are assigned
to the successor corporation (or parent thereof).

          C.   The Plan Administrator shall have the discretionary authority,
exercisable either at the time the unvested shares are issued or any time while
the Corporation's repurchase/cancellation rights remain outstanding under the
Stock Issuance Program, to provide that those rights shall automatically
terminate in whole or in part, and the shares of Common Stock subject to those
terminated rights shall immediately vest, in the event the Participant's Service
should subsequently terminate by reason of an Involuntary Termination within a
designated period (not to exceed eighteen (18) months) following the effective
date of any Change in Control.

  III.    SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held
in escrow by the Corporation until the Participant's interest in such shares
vests or may be issued directly to the Participant with restrictive legends on
the certificates evidencing those unvested shares.

                                  ARTICLE FOUR

                     AUTOMATIC OPTION GRANT/ISSUANCE PROGRAM

    I.    OPTION TERMS

          A.   GRANT DATES.  On the date of each Annual Stockholders Meeting
held after the Effective Date, option grants shall be made to (i) each new
Eligible Director who is elected to the Board at that particular Annual Meeting
and (ii) each continuing Eligible Director who is elected to the Board at that
particular Annual Meeting.  Each automatic option grant shall be a Non-Statutory
Option.  Each Eligible Director shall be granted an option to purchase 15,000
shares of Common Stock at the Annual Meeting at which he or she is first elected
to the Board and an option to purchase 5,000 shares of Common Stock at each
Annual Meeting thereafter at which he or she is elected to the Board.  There
shall be no limit on the number of such automatic option grants any one Eligible
Director may receive over his or her period of Board service, and non-employee

<PAGE>

               1.   The exercise price per share shall be equal to one hundred
percent (100%) of the Fair Market Value per share of Common Stock on the date of
the Annual Stockholders Meeting with respect to which the option is granted.

               2.   The exercise price shall be payable in one or more of the
alternative forms authorized under the Discretionary Option Grant Program.
Except to the extent the sale and remittance procedure specified thereunder is
utilized, payment of the exercise price for the purchased shares must be made on
the Exercise Date.

          C.   OPTION TERM.  Each option shall have a term of ten (10) years
measured from the option grant date.

          D.   EXERCISE AND VESTING OF OPTIONS.  Each option shall be
exercisable only with respect to option shares with respect to which the
automatic option grant has become vested.  Provided that the non-employee
director continues to be a Member of the Board, the 15,000 share option grant
shall vest over four years in successive equal monthly installments from the
date of grant and the 5,000 share option grants shall vest at the end of each
additional year of Service completed by the optionee.  No portion of the
automatic option grant shall vest after the optionee has ceased to be a member
of the Board.

          E.   TERMINATION OF BOARD SERVICE.  The following provisions shall
govern the exercise of any options held by the Optionee at the time the Optionee
ceases to serve as a Board member:

                 (i)     The Optionee (or, in the event of Optionee's
     death, the personal representative of the Optionee's estate or the
     person or persons to whom the option is transferred pursuant to the
     Optionee's will or in accordance with the laws of descent and
     distribution) shall have a twelve (12)-month period following the date
     of such cessation of Board service in which to exercise each such
     option.

                (ii)     During the twelve (12)-month exercise period, the
     option may not be exercised in the aggregate for more than the number
     of vested shares of Common Stock for which the option is exercisable
     at the time of the Optionee's cessation of Board service.

               (iii)     Should the Optionee cease to serve as a Board
     member by reason of death or Permanent Disability, then all shares at
     the time subject to the option shall immediately vest so that such
     option may, during the twelve (12)-month exercise period following
     such cessation of Board service, be exercised for all or any portion
     of those shares as fully-vested shares of Common Stock.

                (iv)     In no event shall the option remain exercisable
     after the expiration of the option term.  Upon the expiration of the
     twelve


                                      -15-
<PAGE>

     (12)-month exercise period or (if earlier) upon the expiration of the
     option term, the option shall terminate and cease to be outstanding for any
     vested shares for which the option has not been exercised.  However, the
     option shall, immediately upon the Optionee's cessation of Board service
     for any reason other than death or Permanent Disability, terminate and
     cease to be outstanding to the extent the option is not otherwise at that
     time exercisable for vested shares.

   II.    CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-OVER

          A.   In the event of any Corporate Transaction, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Corporate Transaction, become fully
exercisable for all of the shares of Common Stock at the time subject to such
option and may be exercised for all or any portion of those shares as fully-
vested shares of Common Stock.  Immediately following the consummation of the
Corporate Transaction, each automatic option grant shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

          B.   In connection with any Change in Control, the shares of Common
Stock at the time subject to each outstanding option but not otherwise vested
shall automatically vest in full so that each such option shall, immediately
prior to the effective date of the Change in Control, become fully exercisable
for all of the shares of Common Stock at the time subject to such option and may
be exercised for all or any portion of those shares as fully-vested shares of
Common Stock.  Each such option shall remain exercisable for such fully-vested
option shares until the expiration or sooner termination of the option term or
the surrender of the option in connection with a Hostile Take-Over.

          C.   Upon the occurrence of a Hostile Take-Over, the Optionee shall
have a thirty (30)-day period in which to surrender to the Corporation each of
his or her outstanding automatic option grants.  The Optionee shall in return be
entitled to a cash distribution from the Corporation in an amount equal to the
excess of (i) the Take-Over Price of the shares of Common Stock at the time
subject to each surrendered option (whether or not the Optionee is otherwise at
the time vested in those shares) over (ii) the aggregate exercise price payable
for such shares.  Such cash distribution shall be paid within five (5) days
following the surrender of the option to the Corporation.  No approval or
consent of the Board or any Plan Administrator shall be required in connection
with such option surrender and cash distribution.

          D.   Each option which is assumed in connection with a Corporate
Transaction shall be appropriately adjusted, immediately after such Corporate
Transaction, to apply to the number and class of securities which would have
been issuable to the Optionee in consummation of such Corporate Transaction had
the option been exercised immediately prior to such Corporate Transaction.
Appropriate adjustments shall also be


                                      -16-
<PAGE>

made to the exercise price payable per share under each outstanding option,
PROVIDED the aggregate exercise price payable for such securities shall remain
the same.

          E.   The grant of options under the Automatic Option Grant Program
shall in no way affect the right of the Corporation to adjust, reclassify,
reorganize or otherwise change its capital or business structure or to merge,
consolidate, dissolve, liquidate or sell or transfer all or any part of its
business or assets.


  III.    REMAINING TERMS

          The remaining terms of each option granted under the Automatic Option
Grant Program shall be the same as the terms in effect for option grants made
under the Discretionary Option Grant Program.

                                  ARTICLE FIVE

                                  MISCELLANEOUS

    I.    FINANCING

          The Plan Administrator may permit any Optionee or Participant to pay
the option exercise price under the Discretionary Option Grant Program or the
purchase price of shares issued under the Stock Issuance Program by delivering a
full-recourse, interest bearing promissory note payable in one or more
installments.  The terms of any such promissory note (including the interest
rate and the terms of repayment) shall be established by the Plan Administrator
in its sole discretion.  In no event may the maximum credit available to the
Optionee or Participant exceed the sum of (i) the aggregate option exercise
price or purchase price payable for the purchased shares plus (ii) any Federal,
state and local income and employment tax liability incurred by the Optionee or
the Participant in connection with the option exercise or share purchase.

   II.    TAX WITHHOLDING

          A.   The Corporation's obligation to deliver shares of Common Stock
upon the exercise of options or the issuance or vesting of such shares under the
Plan shall be subject to the satisfaction of all applicable Federal, state and
local income and employment tax withholding requirements.

          B.   The Plan Administrator may, in its discretion, provide any or all
holders of Non-Statutory Options or unvested shares of Common Stock under the
Plan (other than the options granted or the shares issued under the Automatic
Option Grant Program) with the right to use shares of Common Stock in
satisfaction of all or part of the Taxes incurred by such holders in connection
with the exercise of their options or the vesting of their


                                      -17-
<PAGE>

shares.  Such right may be provided to any such holder in either or both of the
following formats:

               STOCK WITHHOLDING:  The election to have the Corporation
withhold, from the shares of Common Stock otherwise issuable upon the exercise
of such Non-Statutory Option or the vesting of such shares, a portion of those
shares with an aggregate Fair Market Value equal to the percentage of the Taxes
(not to exceed one hundred percent (100%)) designated by the holder.

               STOCK DELIVERY:  The election to deliver to the Corporation, at
the time the Non-Statutory Option is exercised or the shares vest, one or more
shares of Common Stock previously acquired by such holder (other than in
connection with the option exercise or share vesting triggering the Taxes) with
an aggregate Fair Market Value equal to the percentage of the Taxes (not to
exceed one hundred percent (100%)) designated by the holder.

  III.    EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective immediately upon the Plan
Effective Date.  Options may be granted under the Discretionary Option Grant or
Automatic Option Grant Program at any time on or after the Plan Effective Date.
However, no options granted under the Plan may be exercised, and no shares shall
be issued under the Plan, until the Plan is approved by the Corporation's
stockholders.  If such stockholder approval is not obtained within twelve (12)
months after the Plan Effective Date, then all options previously granted under
this Plan shall terminate and cease to be outstanding, and no further options
shall be granted and no shares shall be issued under the Plan.

          B.   The Plan shall serve as the successor to the Predecessor Plan,
and no further option grants or direct stock issuances shall be made under the
Predecessor Plan after the Section 12 Registration Date.   All options
outstanding under the Predecessor Plan on the Section 12 Registration Date shall
be incorporated into the Plan at that time and shall be treated as outstanding
options under the Plan.  However, each outstanding option so incorporated shall
continue to be governed solely by the terms of the documents evidencing such
option, and no provision of the Plan shall be deemed to affect or otherwise
modify the rights or obligations of the holders of such incorporated options
with respect to their acquisition of shares of Common Stock.

          C.   One or more provisions of the Plan, including (without
limitation) the option/vesting acceleration provisions of Article Two relating
to Corporate Transactions and Changes in Control, may, in the Plan
Administrator's discretion, be extended to one or more options incorporated from
the Predecessor Plan which do not otherwise contain such provisions.

          D.   The Plan shall terminate upon the EARLIEST of (i) the tenth
anniversary of the Plan Effective Date, (ii) the date on which all shares
available for issuance under the


                                      -18-
<PAGE>

Plan shall have been issued as fully-vested shares or (iii) the termination of
all outstanding options in connection with a Corporate Transaction.  Upon such
plan termination, all outstanding option grants and unvested stock issuances
shall thereafter continue to have force and effect in accordance with the
provisions of the documents evidencing such grants or issuances.

   IV.    AMENDMENT OF THE PLAN

          A.   The Board shall have complete and exclusive power and authority
to amend or modify the Plan in any or all respects.  However, no such amendment
or modification shall adversely affect the rights and obligations with respect
to stock options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require stockholder approval
if so determined by the Board or pursuant to applicable laws or regulations.

          B.   Options to purchase shares of Common Stock may be granted under
the Discretionary Option Grant and shares of Common Stock may be issued under
the Stock Issuance Program that are in each instance in excess of the number of
shares then available for issuance under the Plan, provided any excess shares
actually issued under those programs shall be held in escrow until there is
obtained any required approval of an amendment sufficiently increasing the
number of shares of Common Stock available for issuance under the Plan.  If such
approval is not obtained within twelve (12) months after the date the first such
excess issuances are made, then (i) any unexercised options granted on the basis
of such excess shares shall terminate and cease to be outstanding and (ii) the
Corporation shall promptly refund to the Optionees and the Participants the
exercise or purchase price paid for any excess shares issued under the Plan and
held in escrow, together with interest (at the applicable Short Term Federal
Rate) for the period the shares were held in escrow, and such shares shall
thereupon be automatically cancelled and cease to be outstanding.

    V.    USE OF PROCEEDS

          Any cash proceeds received by the Corporation from the sale of shares
of Common Stock under the Plan shall be used for general corporate purposes.

   VI.    REGULATORY APPROVALS

          A.   The implementation of the Plan, the granting of any stock option
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any granted option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits required
by regulatory authorities having jurisdiction over the Plan, the stock options
granted under it and the shares of Common Stock issued pursuant to it.


                                      -19-
<PAGE>

          B.   No shares of Common Stock or other assets shall be issued or
delivered under the Plan unless and until there shall have been compliance with
all applicable requirements of Federal and state securities laws, including the
filing and effectiveness of the Form S-8 registration statement for the shares
of Common Stock issuable under the Plan, and all applicable listing requirements
of any stock exchange (or the Nasdaq National Market, if applicable) on which
Common Stock is then listed for trading.

  VII.    NO EMPLOYMENT/SERVICE RIGHTS

          Nothing in the Plan shall confer upon the Optionee or the Participant
any right to continue in Service for any period of specific duration or
interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

                           VISTA MEDICAL TECHNOLOGIES, INC.
                                STOCK OPTION AGREEMENT


RECITALS

    A.   The Board has adopted the Plan for the purpose of retaining the
services of selected Employees, non-employee members of the Board or of the
board of directors of any Parent or Subsidiary and consultants and other
independent advisors who provide services to the Corporation (or any Parent or
Subsidiary).

    B.   Optionee is to render valuable services to the Corporation (or a
Parent or Subsidiary), and this Agreement is executed pursuant to, and is
intended to carry out the purposes of, the Plan in connection with the
Corporation's grant of an option to Optionee.

    C.   All capitalized terms in this Agreement shall have the meaning
assigned to them in the attached Appendix.

         NOW, THEREFORE, it is hereby agreed as follows:

         1.   GRANT OF OPTION.  The Corporation hereby grants to Optionee, as
of the Grant Date, an option to purchase up to the number of Option Shares
specified in the Grant Notice.  The Option Shares shall be purchasable from time
to time during the option term specified in Paragraph 2 at the Exercise Price.

         2.   OPTION TERM.  This option shall have a term of ten (10) years
measured from the Grant Date and shall accordingly expire at the close of
business on the Expiration Date, unless sooner terminated in accordance with
Paragraph 5 or 6.

         3.   LIMITED TRANSFERABILITY.  If this option is designated an
Incentive Option in the Grant Notice, then this option shall be neither
transferable nor assignable by Optionee other than by will or by the laws of
descent and distribution following Optionee's death and may be exercised, during
Optionee's lifetime, only by Optionee.  However, if this option is designated a
Non-Statutory Option in the Grant Notice, then this option may also be assigned
in whole or in part during Optionee's lifetime. The assigned portion shall be
exercisable only by the person or persons who acquire a proprietary interest in
the option pursuant to such assignment.  The terms applicable to the assigned
portion shall be the same as those in effect for this option immediately prior
to such assignment and shall be set forth in such documents issued to the
assignee as the Plan Administrator may deem appropriate.

         4.   DATES OF EXERCISE.  This option shall become exercisable for the
Option Shares in one or more installments as specified in the Grant Notice.  As
the option becomes

<PAGE>

exercisable for such installments, those installments shall accumulate and the
option shall remain exercisable for the accumulated installments until the
Expiration Date or sooner termination of the option term under Paragraph 5 or 6.

         5.   CESSATION OF SERVICE.  The option term specified in Paragraph 2
shall terminate (and this option shall cease to be outstanding) prior to the
Expiration Date should any of the following provisions become applicable:

                (i)     Should Optionee cease to remain in Service for any
    reason (other than death, Permanent Disability or Misconduct) while
    this option is outstanding, then Optionee shall have a period of three
    (3) months (commencing with the date of such cessation of Service)
    during which to exercise this option, but in no event shall this
    option be exercisable at any time after the Expiration Date.

               (ii)     Should Optionee die while this option is
    outstanding, then the personal representative of Optionee's estate or
    the person or persons to whom the option is transferred pursuant to
    Optionee's will or in accordance with the laws of descent and
    distribution shall have the right to exercise this option.  Such right
    shall lapse, and this option shall cease to be outstanding, upon the
    EARLIER of (A) the expiration of the twelve (12)- month period
    measured from the date of Optionee's death or (B) the Expiration Date.

              (iii)     Should Optionee cease Service by reason of
    Permanent Disability while this option is outstanding, then Optionee
    shall have a period of twelve (12) months (commencing with the date of
    such cessation of Service) during which to exercise this option.  In
    no event shall this option be exercisable at any time after the
    Expiration Date.

               (iv)     During the limited period of post-Service
    exercisability, this option may not be exercised in the aggregate for
    more than the number of vested Option Shares for which the option is
    exercisable at the time of Optionee's cessation of Service.  Upon the
    expiration of such limited exercise period or (if earlier) upon the
    Expiration Date, this option shall terminate and cease to be
    outstanding for any vested Option Shares for which the option has not
    been exercised.  However, this option shall, immediately upon
    Optionee's cessation of Service for any reason, terminate and cease to
    be outstanding with respect to any Option Shares in which Optionee is
    not otherwise at that time vested or for which this option is not
    otherwise at that time exercisable.


                                          2.


<PAGE>

                   (v)  Should Optionee's Service be terminated for
    Misconduct, then this option shall terminate immediately and cease to
    remain outstanding.

         6.   SPECIAL ACCELERATION OF OPTION.

              (a)  This option, to the extent outstanding at the time of a
Corporate Transaction but not otherwise fully exercisable, shall automatically
accelerate so that this option shall, immediately prior to the effective date of
the Corporate Transaction, become exercisable for all of the Option Shares at
the time subject to this option and may be exercised for any or all of those
Option Shares as fully-vested shares of Common Stock.  No such acceleration of
this option, however, shall occur if and to the extent: (i) this option is, in
connection with the Corporate Transaction, either to be assumed by the successor
corporation (or parent thereof) or to be replaced with a comparable option to
purchase shares of the capital stock of the successor corporation (or parent
thereof) or (ii) this option is to be replaced with a cash incentive program of
the successor corporation which preserves the spread existing on the unvested
Option Shares at the time of the Corporate Transaction (the excess of the Fair
Market Value of those Option Shares over the aggregate Exercise Price payable
for such shares) and provides for subsequent pay-out in accordance with the
option exercise/vesting schedule set forth in the Grant Notice.  The
determination of option comparability under clause (i) shall be made by the Plan
Administrator, and such determination shall be final, binding and conclusive.

              (b)  Immediately following the Corporate Transaction, this option
shall terminate and cease to be outstanding, except  to the extent assumed by
the successor corporation (or parent thereof) in connection with the Corporate
Transaction.

              (c)  If this option is assumed in connection with a Corporate
Transaction, then this option shall be appropriately adjusted, immediately after
such Corporate Transaction, to apply to the number and class of securities which
would have been issuable to Optionee in consummation of such Corporate
Transaction had the option been exercised immediately prior to such Corporate
Transaction, and appropriate adjustments shall also be made to the Exercise
Price, PROVIDED the aggregate Exercise Price shall remain the same.

              (d)  This Agreement shall not in any way affect the right of the
Corporation to adjust, reclassify, reorganize or otherwise change its capital or
business structure or to merge, consolidate, dissolve, liquidate or sell or
transfer all or any part of its business or assets.

         7.   ADJUSTMENT IN OPTION SHARES.  Should any change be made to the
Common Stock by reason of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
outstanding Common Stock as a class without the Corporation's receipt of
consideration, appropriate adjustments shall be


                                          3.


<PAGE>

made to (i) the total number and/or class of securities subject to this option
and (ii) the Exercise Price in order to reflect such change and thereby preclude
a dilution or enlargement of benefits hereunder.

         8.   STOCKHOLDER RIGHTS.  The holder of this option shall not have any
stockholder rights with respect to the Option Shares until such person shall
have exercised the option, paid the Exercise Price and become a holder of record
of the purchased shares.

         9.   MANNER OF EXERCISING OPTION.

              (a)  In order to exercise this option with respect to all or any
part of the Option Shares for which this option is at the time exercisable,
Optionee (or any other person or persons exercising the option) must take the
following actions:

                     (i)     Execute and deliver to the Corporation a
    Notice of Exercise for the Option Shares for which the option is
    exercised.

                    (ii)     Pay the aggregate Exercise Price for the
    purchased shares in one or more of the following forms:

                        (A)  cash or check made payable to the
         Corporation;

                        (B)  a promissory note payable to the Corporation,
         but only to the extent authorized by the Plan Administrator in
         accordance with Paragraph 13;

                        (C)  shares of Common Stock held by Optionee (or
         any other person or persons exercising the option) for the
         requisite period necessary to avoid a charge to the Corporation's
         earnings for financial reporting purposes and valued at Fair
         Market Value on the Exercise Date; or

                        (D)  to the extent the option is exercised for
         vested Option Shares, through a special sale and remittance
         procedure pursuant to which Optionee (or any other person or
         persons exercising the option) shall concurrently provide
         irrevocable written instructions (I) to a Corporation-designated
         brokerage firm to effect the immediate sale of the purchased
         shares and remit to the Corporation, out of the sale proceeds
         available on the settlement date, sufficient funds to cover the
         aggregate Exercise Price payable for the purchased shares plus
         all applicable Federal, state and local income and employment
         taxes required to be withheld by the Corporation by reason of
         such exercise and (II) to the Corporation to deliver the
         certificates for the purchased


                                          4.


<PAGE>

         shares directly to such brokerage firm in order to complete the sale
         transaction.

              Except to the extent the sale and remittance procedure is
         utilized in connection with the option exercise, payment of the
         Exercise Price must accompany the Notice of Exercise delivered to
         the Corporation in connection with the option exercise.

                   (iii)     Furnish to the Corporation appropriate
    documentation that the person or persons exercising the option (if
    other than Optionee) have the right to exercise this option.

                    (iv)     Make appropriate arrangements with the
    Corporation (or Parent or Subsidiary employing or retaining Optionee)
    for the satisfaction of all Federal, state and local income and
    employment tax withholding requirements applicable to the option
    exercise.

              (b)  As soon as practical after the Exercise Date, the
Corporation shall issue to or on behalf of Optionee (or any other person or
persons exercising this option) a certificate for the purchased Option Shares,
with the appropriate legends affixed thereto.

              (c)  In no event may this option be exercised for any fractional
shares.

         10.  COMPLIANCE WITH LAWS AND REGULATIONS.

              (a)  The exercise of this option and the issuance of the Option
Shares upon such exercise shall be subject to compliance by the Corporation and
Optionee with all applicable requirements of law relating thereto and with all
applicable regulations of any stock exchange (or the Nasdaq National Market, if
applicable) on which the Common Stock may be listed for trading at the time of
such exercise and issuance.

              (b)  The inability of the Corporation to obtain approval from any
regulatory body having authority deemed by the Corporation to be necessary to
the lawful issuance and sale of any Common Stock pursuant to this option shall
relieve the Corporation of any liability with respect to the non-issuance or
sale of the Common Stock as to which such approval shall not have been obtained.
The Corporation, however, shall use its best efforts to obtain all such
approvals.

         11.  SUCCESSORS AND ASSIGNS.  Except to the extent otherwise provided
in Paragraphs 3 and 6, the provisions of this Agreement shall inure to the
benefit of, and be binding upon, the Corporation and its successors and assigns
and Optionee, Optionee's assigns and the legal representatives, heirs and
legatees of Optionee's estate.


                                          5.


<PAGE>

         12.  NOTICES.  Any notice required to be given or delivered to the
Corporation under the terms of this Agreement shall be in writing and addressed
to the Corporation at its principal corporate offices.  Any notice required to
be given or delivered to Optionee shall be in writing and addressed to Optionee
at the address indicated below Optionee's signature line on the Grant Notice.
All notices shall be deemed effective upon personal delivery or upon deposit in
the U.S. mail, postage prepaid and properly addressed to the party to be
notified.

         13.  FINANCING.  The Plan Administrator may, in its absolute
discretion and without any obligation to do so, permit Optionee to pay the
Exercise Price for the purchased Option Shares by delivering a full-recourse
promissory note payable to the Corporation.  The terms of any such promissory
note (including the interest rate, the requirements for collateral and the terms
of repayment) shall be established by the Plan Administrator in its sole
discretion.

         14.  CONSTRUCTION.  This Agreement and the option evidenced hereby are
made and granted pursuant to the Plan and are in all respects limited by and
subject to the terms of the Plan.  All decisions of the Plan Administrator with
respect to any question or issue arising under the Plan or this Agreement shall
be conclusive and binding on all persons having an interest in this option.

         15.  GOVERNING LAW.  The interpretation, performance and enforcement
of this Agreement shall be governed by the laws of the State of California
without resort to that State's conflict-of-laws rules.

         16.  EXCESS SHARES.  If the Option Shares covered by this Agreement
exceed, as of the Grant Date, the number of shares of Common Stock which may
without stockholder approval be issued under the Plan, then this option shall be
void with respect to those excess shares, unless stockholder approval of an
amendment sufficiently increasing the number of shares of Common Stock issuable
under the Plan is obtained in accordance with the provisions of the Plan.

         17.  ADDITIONAL TERMS APPLICABLE TO AN INCENTIVE OPTION.  In the event
this option is designated an Incentive Option in the Grant Notice, the following
terms and conditions shall also apply to the grant:

              -    This option shall cease to qualify for favorable tax
    treatment as an Incentive Option if (and to the extent) this option is
    exercised for one or more Option Shares: (A) more than three (3)
    months after the date Optionee ceases to be an Employee for any reason
    other than death or Permanent Disability or (B) more than twelve (12)
    months after the date Optionee ceases to be an Employee by reason of
    Permanent Disability.


                                          6.


<PAGE>

              -    No installment under this option shall qualify for
    favorable tax treatment as an Incentive Option if (and to the extent)
    the aggregate Fair Market Value (determined at the Grant Date) of the
    Common Stock for which such installment first becomes exercisable
    hereunder would, when added to the aggregate value (determined as of
    the respective date or dates of grant) of the Common Stock or other
    securities for which this option or any other Incentive Options
    granted to Optionee prior to the Grant Date (whether under the Plan or
    any other option plan of the Corporation or any Parent or Subsidiary)
    first become exercisable during the same calendar year, exceed One
    Hundred Thousand Dollars ($100,000) in the aggregate.  Should such One
    Hundred Thousand Dollar ($100,000) limitation be exceeded in any
    calendar year, this option shall nevertheless become exercisable for
    the excess shares in such calendar year as a Non-Statutory Option.

              -    Should the exercisability of this option be accelerated
    upon a Corporate Transaction, then this option shall qualify for
    favorable tax treatment as an Incentive Option only to the extent the
    aggregate Fair Market Value (determined at the Grant Date) of the
    Common Stock for which this option first becomes exercisable in the
    calendar year in which the Corporate Transaction occurs does not, when
    added to the aggregate value (determined as of the respective date or
    dates of grant) of the Common Stock or other securities for which this
    option or one or more other Incentive Options granted to Optionee
    prior to the Grant Date (whether under the Plan or any other option
    plan of the Corporation or any Parent or Subsidiary) first become
    exercisable during the same calendar year, exceed One Hundred Thousand
    Dollars ($100,000) in the aggregate.  Should the applicable One
    Hundred Thousand Dollar ($100,000) limitation be exceeded in the
    calendar year of such Corporate Transaction, the option may
    nevertheless be exercised for the excess shares in such calendar year
    as a Non-Statutory Option.

              -    Should Optionee hold, in addition to this option, one
    or more other options to purchase Common Stock which become
    exercisable for the first time in the same calendar year as this
    option, then the foregoing limitations on the exercisability of such
    options as Incentive Options shall be applied on the basis of the
    order in which such options are granted.

         18.  LEAVE OF ABSENCE.  The following provisions shall apply upon the
Optionee's commencement of an authorized leave of absence:

              (a)  The exercise schedule in effect under the Grant Notice
    shall be frozen as of the first day of the authorized leave, and this
    option shall not become exercisable for any additional installments of
    the Option Shares during the period Optionee remains on such leave.


                                          7.


<PAGE>

              (b)  Should Optionee resume active Employee status within
    sixty (60) days after the start date of the authorized leave, Optionee
    shall, for purposes of the exercise schedule set forth in the Grant
    Notice, receive Service credit for the entire period of such leave.
    If Optionee does not resume active Employee status within such sixty
    (60)-day period, then no Service credit shall be given for the period
    of such leave.

              (c)  If the option is designated as an Incentive Option in
    the Grant Notice, then the following additional provision shall apply:

                   -    If the leave of absence continues for more than
         ninety (90) days, then this option shall automatically convert to
         a Non-Statutory Option under the Federal tax laws on the
         ninety-first (91st) day of such leave, unless the Optionee's
         reemployment rights are guaranteed by statute or by written
         agreement.  Following any such conversion of the option, all
         subsequent exercises of such option, whether effected before or
         after Optionee's return to active Employee status, shall result
         in an immediate taxable event, and the Corporation shall be
         required to collect from Optionee the Federal, state and local
         income and employment withholding taxes applicable to such
         exercise.

              (d)  In no event shall this option become exercisable for
    any additional Option Shares or otherwise remain outstanding if
    Optionee does not resume Employee status prior to the Expiration Date
    of the option term.

                                          8.

                        VISTA MEDICAL TECHNOLOGIES, INC.
                          EMPLOYEE STOCK PURCHASE PLAN


   I.     PURPOSE OF THE PLAN

          This Employee Stock Purchase Plan is intended to promote the interests
of Vista Medical Technologies, Inc., a Delaware corporation, by providing
eligible employees with the opportunity to acquire a proprietary interest in the
Corporation through participation in a payroll-deduction based employee stock
purchase plan designed to qualify under Section 423 of the Code.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

  II.     ADMINISTRATION OF THE PLAN

          The Plan Administrator shall have full authority to interpret and
construe any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Code Section 423.  Decisions of the Plan Administrator shall be
final and binding on all parties having an interest in the Plan.

 III.     STOCK SUBJECT TO PLAN

          A.   The stock purchasable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock, including shares of Common
Stock purchased on the open market.  The maximum number of shares of Common
Stock which may be issued over the term of the Plan shall not exceed Two Hundred
Thousand (200,000) shares.

          B.   Should any change be made to the Common Stock by reason of any
stock split, stock dividend, recapitalization, combination of shares, exchange
of shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration, appropriate adjustments
shall be made to (i) the maximum number and class of securities issuable under
the Plan, (ii) the maximum number and class of securities purchasable per
Participant on any one Purchase Date and (iii) the number and class of
securities and the price per share in effect under each outstanding purchase
right in order to prevent the dilution or enlargement of benefits thereunder.

<PAGE>

  IV.     OFFERING PERIODS

          A.   Shares of Common Stock shall be offered for purchase under the
Plan through a series of successive offering periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

          B.   The initial offering period shall commence as of the Effective
Date of the Plan and shall continue until March 31, 1999.  Thereafter, each
successive offering period shall be of 24 months duration.  The next offering
period shall commence on the first business day in April 1999, and subsequent
offering periods shall commence as designated by the Plan Administrator.
Notwithstanding the above, the Plan Administrator may shorten the duration of
any offering period to less than twenty-four (24) months provided that such
action is taken prior to the start date of such offering period.

          C.   Each offering period shall be comprised of a series of one or
more successive Purchase Intervals.  Purchase Intervals shall run from the first
business day in April each year to the last business day in September of the
same year and from the first business day in October each year to the last
business day in March of the following year.  Accordingly, the first Purchase
Interval in effect under the initial offering period shall commence at the
Effective Time and terminate on the last business day in September 1997.

          D.   Should the Fair Market Value per share of Common Stock on any
Purchase Date within an offering period be less than the Fair Market Value per
share of Common Stock on the start date of that offering period, then that
offering period shall automatically terminate immediately after the purchase of
shares of Common Stock on such Purchase Date, and a new offering period shall
commence on the next business day following such Purchase Date.  The new
offering period shall have a duration of twenty four (24) months, unless a
shorter duration is established by the Plan Administrator within five (5)
business days following the start date of that offering period.

   V.     ELIGIBILITY

          A.   Each individual who is an Eligible Employee on the start date of
any offering period under the Plan may enter that offering period on such start
date or on any subsequent Semi-Annual Entry Date within that offering period,
provided he or she remains an Eligible Employee.

          B.   Each individual who first becomes an Eligible Employee after the
start date of an offering period may enter that offering period on any
subsequent Semi-Annual Entry Date within that offering period on which he or she
is an Eligible Employee.

          C.   The date an individual enters an offering period shall be
designated his or her Entry Date for purposes of that offering period.


                                       2.
<PAGE>

          D.   To participate in the Plan for a particular offering period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

  VI.     PAYROLL DEDUCTIONS

          A.   The payroll deduction authorized by the Participant for purposes
of acquiring shares of Common Stock during an offering period may be any
multiple of one percent (1%) of the Base Salary paid to the Participant during
each Purchase Interval within that offering period, up to a maximum of ten
percent (10%).  The deduction rate so authorized shall continue in effect
throughout the offering period, except to the extent such rate is changed in
accordance with the following guidelines:

                 (i)     The Participant may, at any time during the
     offering period, reduce his or her rate of payroll deduction to become
     effective as soon as possible after filing the appropriate form with
     the Plan Administrator.  The Participant may not, however, effect more
     than one (1) such reduction per Purchase Interval.

                (ii)     The Participant may, prior to the commencement of
     any new Purchase Interval within the offering period, increase the
     rate of his or her payroll deduction by filing the appropriate form
     with the Plan Administrator.  The new rate (which may not exceed the
     ten percent (10%) maximum) shall become effective on the start date of
     the first Purchase Interval following the filing of such form.

          B.   Payroll deductions shall begin on the first pay day following the
Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of that offering period.  The amounts so
collected shall be credited to the Participant's book account under the Plan,
but no interest shall be paid on the balance from time to time outstanding in
such account.  The amounts collected from the Participant shall not be held in
any segregated account or trust fund and may be commingled with the general
assets of the Corporation and used for general corporate purposes.

          C.   Payroll deductions shall automatically cease upon the termination
of the Participant's purchase right in accordance with the provisions of the
Plan.

          D.   The Participant's acquisition of Common Stock under the Plan on
any Purchase Date shall neither limit nor require the Participant's acquisition
of Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.


                                       3.

   VII.    PURCHASE RIGHTS

          A.   GRANT OF PURCHASE RIGHT.  A Participant shall be granted a
separate purchase right for each offering period in which he or she
participates.  The purchase right shall be granted on the Participant's Entry
Date into the offering period and shall provide the Participant with the right
to purchase shares of Common Stock, in a series of successive installments over
the remainder of such offering period, upon the terms set forth below.  The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

          Under no circumstances shall purchase rights be granted under the Plan
to any Eligible Employee if such individual would, immediately after the grant,
own (within the meaning of Code Section 424(d)) or hold outstanding options or
other rights to purchase, stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Corporation
or any Corporate Affiliate.

          B.   EXERCISE OF THE PURCHASE RIGHT.  Each purchase right shall be
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant (other than Participants whose payroll deductions
have previously been refunded pursuant to the Termination of Purchase Right
provisions below) on each such Purchase Date.  The purchase shall be effected by
applying the Participant's payroll deductions for the Purchase Interval ending
on such Purchase Date to the purchase of whole shares of Common Stock at the
purchase price in effect for the Participant for that Purchase Date.

          C.   PURCHASE PRICE.  The purchase price per share at which Common
Stock will be purchased on the Participant's behalf on each Purchase Date within
the offering period shall not be less than eighty-five percent (85%) of the
LOWER of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into that offering period or (ii) the Fair Market Value
per share of Common Stock on that Purchase Date.

          D.   NUMBER OF PURCHASABLE SHARES.  The number of shares of Common
Stock purchasable by a Participant on each Purchase Date during the offering
period shall be the number of whole shares obtained by dividing the amount
collected from the Participant through payroll deductions during the Purchase
Interval ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date.

          E.   EXCESS PAYROLL DEDUCTIONS.  Any payroll deductions not applied to
the  purchase of shares of Common Stock on any Purchase Date because they are
not sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date.  However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable by the Participant on the
Purchase Date shall be promptly refunded.


                                       4.
<PAGE>

          F.   TERMINATION OF PURCHASE RIGHT.  The following provisions shall
govern the termination of outstanding purchase rights:

                 (i)     A Participant may, at any time prior to the next
     scheduled Purchase Date in the offering period, terminate his or her
     outstanding purchase right by filing the appropriate form with the
     Plan Administrator (or its designate), and no further payroll
     deductions shall be collected from the Participant with respect to the
     terminated purchase right.  Any payroll deductions collected during
     the Purchase Interval in which such termination occurs shall, at the
     Participant's election, be immediately refunded or held for the
     purchase of shares on the next Purchase Date.  If no such election is
     made at the time such purchase right is terminated, then the payroll
     deductions collected with respect to the terminated right shall be
     refunded as soon as possible.

                (ii)     The termination of such purchase right shall be
     irrevocable, and the Participant may not subsequently rejoin the
     offering period for which the terminated purchase right was granted.
     In order to resume participation in any subsequent offering period,
     such individual must re-enroll in the Plan (by making a timely filing
     of the prescribed enrollment forms) on or before his or her scheduled
     Entry Date into that offering period.

               (iii)     Should the Participant cease to remain an Eligible
     Employee for any reason (including death, disability or change in
     status) while his or her purchase right remains outstanding, then that
     purchase right shall immediately terminate, and all of the
     Participant's payroll deductions for the Purchase Interval in which
     the purchase right so terminates shall be immediately refunded.
     However, should the Participant cease to remain in active service by
     reason of an approved unpaid leave of absence, then the Participant
     shall have the right, exercisable up until the last business day of
     the Purchase Interval in which such leave commences, to (a) withdraw
     all the payroll deductions collected to date on his or her behalf for
     that Purchase Interval or (b) have such funds held for the purchase of
     shares on his or her behalf on the next scheduled Purchase Date.  In
     no event, however, shall any further payroll deductions be collected
     on the Participant's behalf during such leave.  Upon the Participant's
     return to active service, his or her payroll deductions under the Plan
     shall automatically resume at the rate in effect at the time the leave
     began, unless the Participant withdraws from the Plan prior to his or
     her return.

          G.   CORPORATE TRANSACTION.  Each outstanding purchase right shall
automatically be exercised, immediately prior to the effective date of any
Corporate Transaction, by applying the payroll deductions of each Participant
for the Purchase Interval in which such Corporate Transaction occurs to the
purchase of whole shares of Common


                                       5.
<PAGE>

Stock at a purchase price per share not less than eighty-five percent (85%) of
the LOWER of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into the offering period in which such Corporate
Transaction occurs or (ii) the Fair Market Value per share of Common Stock
immediately prior to the effective date of such Corporate Transaction.  However,
the applicable limitation on the number of shares of Common Stock purchasable
per Participant shall continue to apply to any such purchase.

          The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Corporate Transaction,
and Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Corporate Transaction.

          H.   PRORATION OF PURCHASE RIGHTS.  Should the total number of shares
of Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

          I.   ASSIGNABILITY.  The purchase right shall be exercisable only by
the Participant and shall not be assignable or transferable by the Participant.

          J.   STOCKHOLDER RIGHTS.  A Participant shall have no stockholder
rights with respect to the shares subject to his or her outstanding purchase
right until the shares are purchased on the Participant's behalf in accordance
with the provisions of the Plan and the Participant has become a holder of
record of the purchased shares.

 VIII.    ACCRUAL LIMITATIONS

          A.   No Participant shall be entitled to accrue rights to acquire
Common Stock pursuant to any purchase right outstanding under this Plan if and
to the extent such accrual, when aggregated with (i) rights to purchase Common
Stock accrued under any other purchase right granted under this Plan and (ii)
similar rights accrued under other employee stock purchase plans (within the
meaning of Code Section 423) of the Corporation or any Corporate Affiliate,
would otherwise permit such Participant to purchase more than Twenty-Five
Thousand Dollars ($25,000) worth of stock of the Corporation or any Corporate
Affiliate (determined on the basis of the Fair Market Value per share on the
date or dates such rights are granted) for each calendar year such rights are at
any time outstanding.

          B.   For purposes of applying such accrual limitations to the purchase
rights granted under the Plan, the following provisions shall be in effect:


                                       6.
<PAGE>

                 (i)     The right to acquire Common Stock under each
     outstanding purchase right shall accrue in a series of installments on
     each successive Purchase Date during the offering period on which such
     right remains outstanding.

                (ii)     No right to acquire Common Stock under any
     outstanding purchase right shall accrue to the extent the Participant
     has already accrued in the same calendar year the right to acquire
     Common Stock under one (1) or more other purchase rights at a rate
     equal to Twenty-Five Thousand Dollars ($25,000) worth of Common Stock
     (determined on the basis of the Fair Market Value per share on the
     date or dates of grant) for each calendar year such rights were at any
     time outstanding.

          C.   If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions which the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

          D.   In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

   IX.    EFFECTIVE DATE AND TERM OF THE PLAN

          A.   The Plan shall become effective at the Effective Time, PROVIDED
no purchase rights granted under the Plan shall be exercised, and no shares of
Common Stock shall be issued hereunder, until (i) the Plan shall have been
approved by the stockholders of the Corporation and (ii) the Corporation shall
have complied with all applicable requirements of the 1933 Act (including the
registration of the shares of Common Stock issuable under the Plan on a Form S-8
registration statement filed with the Securities and Exchange Commission), all
applicable listing requirements of any stock exchange (or the Nasdaq National
Market, if applicable) on which the Common Stock is listed for trading and all
other applicable requirements established by law or regulation.  In the event
such stockholder approval is not obtained, or such compliance is not effected,
within twelve (12) months after the date on which the Plan is adopted by the
Board, the Plan shall terminate and have no further force or effect, and all
sums collected from Participants during the initial offering period hereunder
shall be refunded.

          B.   Unless sooner terminated by the Board, the Plan shall terminate
upon the EARLIEST of (i) the last business day in March 2007, (ii) the date on
which all shares available for issuance under the Plan shall have been sold
pursuant to purchase rights exercised under the Plan or (iii) the date on which
all purchase rights are exercised in connection with a Corporate Transaction.
No further purchase rights shall be granted or


                                       7.
<PAGE>

exercised, and no further payroll deductions shall be collected, under the Plan
following such termination.

    X.    AMENDMENT OF THE PLAN

          The Board may alter, amend, suspend or discontinue the Plan at any
time to become effective immediately following the close of any Purchase
Interval.  However, the Board may not, without the approval of the Corporation's
stockholders, (i) materially increase the number of shares of Common Stock
issuable under the Plan or the maximum number of shares purchasable per
Participant on any one Purchase Date, except for permissible adjustments in the
event of certain changes in the Corporation's capitalization, (ii) alter the
purchase price formula so as to reduce the purchase price payable for the shares
of Common Stock purchasable under the Plan or (iii) materially increase the
benefits accruing to Participants under the Plan or materially modify the
requirements for eligibility to participate in the Plan.

     XI.  GENERAL PROVISIONS

          A.   All costs and expenses incurred in the administration of the Plan
shall be paid by the Corporation.

          B.   Nothing in the Plan shall confer upon the Participant any right
to continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment  at any time for any reason, with or without
cause.

          C.   The provisions of the Plan shall be governed by the laws of the
State of Delaware without resort to that State's conflict-of-laws rules.

                              INDEMNIFICATION AGREEMENT



    THIS AGREEMENT is made and entered into this _____ day of April, 1997
between Vista Medical Technologies, Inc., a Delaware corporation (the
"Corporation"), and Nicholas B. Binkley ("Director").

                                      RECITALS:

    A.    Director, a member of the Board of Directors of the Corporation,
performs a valuable service in such capacity for the Corporation; and

    B.    The stockholders of the Corporation have adopted Bylaws (the
"Bylaws") providing for the indemnification of the officers, directors, agents
and employees of the Corporation to the maximum extent authorized by Section 145
of the Delaware General Corporation Law, as amended (the "Law"); and

    C.    The Bylaws and the Law, by their non-exclusive nature, permit
contracts between the Corporation and the members of its Board of Directors with
respect to indemnification of such directors; and

    D.   In accordance with the authorization as provided by the Law, the
Corporation may from time to time purchase and maintain a policy or policies of
Directors and Officers Liability Insurance ("D & O Insurance"), covering certain
liabilities which may be incurred by its directors and officers in the
performance of services as directors and officers of the Corporation; and

    E.   As a result of developments affecting the terms, scope and
availability of D & O Insurance there exists general uncertainty as to the
extent and overall desirability of protection afforded members of the Board of
Directors by such D & O Insurance, if any, and by statutory and bylaw
indemnification provisions; and

    F.   In order to induce Director to continue to serve as a member of the
Board of Directors of the Corporation, the Corporation has determined and agreed
to enter into this contract with Director;

    NOW, THEREFORE, in consideration of Director's continued service as a
director after the date hereof, the parties hereto agree as follows:

    1.   INDEMNITY OF DIRECTOR.  The Corporation hereby agrees to hold harmless
and indemnify Director to the fullest extent authorized or permitted by the
provisions of the Law, as may be amended from time to time.


<PAGE>

    2.   ADDITIONAL INDEMNITY.  Subject only to the exclusions set forth in
Section 3 hereof, the Corporation hereby further agrees to hold harmless and
indemnify Director:

         (a)  against any and all expenses (including attorneys' fees), witness
fees, judgments, fines and amounts paid in settlement actually and reasonably
incurred by Director in connection with any threatened, pending or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative (including an action by or in the right of the Corporation) to
which Director is, was or at any time becomes a party, or is threatened to be
made a party, by reason of the fact that Director is, was or at any time becomes
a director, officer, employee or agent of the Corporation, or is or was serving
or at any time serves at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise; and

         (b)  otherwise to the fullest extent as may be provided to Director by
the Corporation under the non-exclusivity provisions of the Bylaws of the
Corporation and the Law.

    3.   LIMITATIONS ON ADDITIONAL INDEMNITY.  No indemnity pursuant to Section
2 hereof shall be paid by the Corporation:

         (a)  except to the extent the aggregate of losses to be indemnified
thereunder exceeds the sum of such losses for which the Director is indemnified
pursuant to Section 1 hereof or pursuant to any D & O Insurance purchased and
maintained by the Corporation;

         (b)  in respect of remuneration paid to Director if it shall be
determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

         (c)  on account of any action, suit or proceeding in which judgment is
rendered against Director for an accounting of profits made from the purchase or
sale by Director of securities of the Corporation pursuant to the provisions of
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or
similar provisions of any federal, state or local statutory law;

         (d)  on account of Director's conduct which is finally adjudged to
have been knowingly fraudulent or deliberately dishonest, or to constitute
willful misconduct;

         (e)  on account of Director's conduct which is the subject of an
action, suit or proceeding described in Section 7(c)(ii) hereof;

         (f)  on account of or arising in response to any action, suit or
proceeding (other than an action, suit or proceeding referred to in Section 8(b)
hereof) initiated by Director or any of Director's affiliates against the
Corporation or any officer, director or



                                         -2-

<PAGE>

stockholder of the Corporation unless such action, suit or proceeding was
authorized in the specific case by action of the Board of Directors of the
Corporation;

         (g)  on account of any action, suit or proceeding to the extent that
Director is a plaintiff, a counter-complainant or a cross-complainant therein
(other than an action, suit or proceeding permitted by Section 3(f) hereof); or

         (h)  if a final decision by a Court having jurisdiction in the matter
shall determine that such indemnification is not lawful (and, in this respect,
both the Corporation and Director have been advised that the Securities and
Exchange Commission believes that indemnification for liabilities arising under
the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication).

    4.   CONTRIBUTION.  If the indemnification provided in Sections 1 and 2 is
unavailable and may not be paid to Director for any reason other than those set
forth in paragraphs (b) through (g) of Section 3, then in respect of any
threatened, pending or completed action, suit or proceeding in which the
Corporation is or is alleged to be jointly liable with Director (or would be if
joined in such action, suit or proceeding), the Corporation shall contribute to
the amount of expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred and paid or payable by
Director in such proportion as is appropriate to reflect (i) the relative
benefits received by the Corporation on the one hand and Director on the other
hand from the transaction from which such action, suit or proceeding arose, and
(ii) the relative fault of the Corporation on the one hand and of Director on
the other hand in connection with the events which resulted in such expenses,
judgments, fines or settlement amounts, as well as any other relevant equitable
considerations. The relative fault of the Corporation on the one hand and of
Director on the other shall be determined by reference to, among other things,
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent the circumstances resulting in such expenses, judgments,
fines or settlement amounts.  The Corporation agrees that it would not be just
and equitable if contribution pursuant to this Section 4 were determined by pro
rata allocation or any other method of allocation which does not take account of
the foregoing equitable considerations.

    5.   CONTINUATION OF OBLIGATIONS.

         (a)   All agreements and obligations of the Corporation contained
herein shall continue during the period Director is a director, officer,
employee or agent of the Corporation (or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise)
and shall continue thereafter so long as Director shall be subject to any
possible claim or threatened, pending or completed action, suit or proceeding,
whether civil, criminal or investigative, by reason of the fact that Director
was serving the Corporation or such other entity in any capacity referred to
herein.



                                         -3-

<PAGE>


         (b)   For six years after the effective time of (i) the acquisition of
the Corporation by another entity by means of any transaction or series of
related transactions (including, without limitation, any reorganization, merger
or consolidation) or (ii) the sale of all or substantially all of the assets of
the Corporation by means of any transaction or series of related transactions,
the Corporation (to the extent the Corporation is not the continuing or
surviving person of such reorganization, merger, consolidation or sale) shall
cause the acquiring, continuing or surviving corporation to (x) indemnify and
hold harmless Director in accordance with Sections 1 and 2 hereof and (y) use
its best efforts to provide directors' liability  insurance on terms
substantially similar to the terms of the Corporation's then current directors'
liability insurance policy in effect on the dated thereof, or any other
arrangement reasonably satisfactory to Director, in respect of acts or omissions
occurring on or prior to the effective time of the reorganization, merger,
consolidation or sale.

    6.   NOTIFICATION AND DEFENSE OF CLAIM.  Not later than thirty (30) days
after receipt by Director of notice of the commencement of any action, suit or
proceeding, Director will, if a claim in respect thereof is to be made against
the Corporation under this Agreement, notify the Corporation of the commencement
thereof; but the omission so to notify the Corporation will not relieve it from
any liability which it may have to Director otherwise than under this Agreement.
With respect to any such action, suit or proceeding as to which Director
notifies the Corporation of the commencement thereof:

         (a)  The Corporation will be entitled to participate therein at its
own expense;

         (b)  Except as otherwise provided below, to the extent that it may
wish, the Corporation jointly with any other indemnifying party similarly
notified will be entitled to assume the defense thereof, with counsel reasonably
satisfactory to Director.  After notice from the Corporation to Director of its
election so as to assume the defense thereof, the Corporation will not be liable
to Director under this Agreement for any legal or other expenses subsequently
incurred by Director in connection with the defense thereof other than
reasonable costs of investigation or as otherwise provided below.  Director
shall have the right to employ his own counsel in such action, suit or
proceeding but the fees and expenses of such counsel incurred after notice from
the Corporation of its assumption of the defense thereof shall be at the expense
of Director unless (i) the employment of counsel by Director has been authorized
by the Corporation, (ii) Director shall have reasonably concluded that there may
be a conflict of interest between the Corporation and Director in the conduct of
the defense of such action or (iii) the Corporation shall not in fact have
employed counsel to assume the defense of such action, in each of which cases
the fees and expenses of Director's separate counsel shall be at the expense of
the Corporation.  The Corporation shall not be entitled to assume the defense of
any action, suit or proceeding brought by or on behalf of the Corporation or as
to which Director shall have made the conclusion provided for in (ii) above; and

         (c)  The Corporation shall not be liable to indemnify Director under
this Agreement for any amounts paid in settlement of any action or claim
effected without its



                                         -4-

<PAGE>

written consent.  The Corporation shall be permitted to settle any action except
that it shall not settle any action or claim in any manner which would impose
any penalty, out-of-pocket liability, or limitation on Director without
Director's written consent.  Neither the Corporation nor Director will
unreasonably withhold its or his consent to any proposed settlement.

    7.   ADVANCEMENT AND REPAYMENT OF EXPENSES.

         (a)  In the event that Director employs his own counsel pursuant to
Section 6(b)(i) through (iii) above, the Corporation shall advance to Director,
prior to any final disposition of any threatened or pending action, suit or
proceeding, whether civil, criminal, administrative or investigative, any and
all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding within ten (10)
days after receiving copies of invoices presented to Director for such expenses.

         (b)  Director agrees that Director will reimburse the Corporation for
all reasonable expenses paid by the Corporation in defending any civil or
criminal action, suit or proceeding against Director in the event and only to
the extent it shall be ultimately determined by a final judicial decision (from
which there is no right of appeal) that Director is not entitled, under the
provisions of the Law, the Bylaws, this Agreement or otherwise, to be
indemnified by the Corporation for such expenses.

         (c)  Notwithstanding the foregoing, the Corporation shall not be
required to advance such expenses to Director if Director (i) commences any
action, suit or proceeding as a plaintiff unless such advance is specifically
approved by a majority of the Board of Directors or (ii) is a party to an
action, suit or proceeding brought by the Corporation and approved by a majority
of the Board which alleges willful misappropriation of corporate assets by
Director, disclosure of confidential information in violation of Director's
fiduciary or contractual obligations to the Corporation, or any other willful
and deliberate breach in bad faith of Director's duty to the Corporation or its
stockholders.

    8.   ENFORCEMENT.

         (a)  The Corporation expressly confirms and agrees that it has entered
into this Agreement and assumed the obligations imposed on the Corporation
hereby in order to induce Director to continue as a director of the Corporation,
and acknowledges that Director is relying upon this Agreement in continuing in
such capacity.

         (b)  In the event Director is required to bring any action to enforce
rights or to collect moneys due under this Agreement and is successful in such
action, the Corporation shall reimburse Director for all Director's reasonable
fees and expenses in bringing and pursuing such action.



                                         -5-

<PAGE>


    9.   SUBROGATION.  In the event of payment under this agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Director, who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

    10.  NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on Director by this
Agreement shall not be exclusive of any  other right which Director may have or
hereafter acquire under any statute, provision of the Corporation's Certificate
of Incorporation or Bylaws, agreement, vote of stockholders or directors, or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding office.

    11.  SURVIVAL OF RIGHTS.  The rights conferred on Director by this
Agreement shall continue after Director has ceased to be a director, officer,
employee or other agent of the Corporation or such other entity and shall inure
to the benefit of Director's heirs, executors and administrators.

    12.  SEPARABILITY.  Each of the provisions of this Agreement is a separate
and distinct agreement and independent of the others, so that if any or all of
the provisions hereof shall be held to be invalid or unenforceable to any extent
for any reason, such invalidity or unenforceability shall not affect the
validity or enforceability of the other provisions hereof or the obligation of
the Corporation to indemnify the Director to the full extent provided by the
Bylaws or the Law, and the affected provision shall be construed and enforced so
as to effectuate the parties' intent to the maximum extent possible.

    13.  GOVERNING LAW.  This Agreement shall be interpreted and enforced in
accordance with the internal laws of the State of Delaware.

    14.  BINDING EFFECT.  This Agreement shall be binding upon Director and
upon the Corporation, its successors and assigns, and shall inure to the benefit
of Director, his heirs, personal representatives and assigns and to the benefit
of the Corporation, its successors and assigns.

    15.  AMENDMENT AND TERMINATION.  No amendment, modification, termination or
cancellation of this Agreement shall be effective unless set forth in a writing
signed by both parties hereto.

                            INDEMNIFICATION AGREEMENT



     THIS AGREEMENT is made and entered into this _____ day of _____, 19__
between Vista Medical Technologies, Inc., a Delaware corporation (the
"Corporation"), and ____________ ("Officer").

                                    RECITALS:

     A.   Officer, an officer (but not currently a member of the Board of
Directors) of the Corporation, performs a valuable service in such capacity for
the Corporation; and

     B.   The stockholders of the Corporation have adopted Bylaws (the "Bylaws")
providing, for the indemnification of the officers, directors, agents and
employees of Corporation to the maximum extent authorized by Section 145 of the
Delaware General Corporation Law, as amended (the "Law"); and

     C.   The Bylaws and the Law, by their non-exclusive nature, permit
contracts between the Corporation and its officers with respect to
indemnification of officers; and

     D.   In accordance with the authorization as provided by the Law, the
Corporation may from time to time purchase and maintain a policy or policies of
Directors and Officers Liability Insurance ("D & O Insurance"), covering certain
liabilities which may be incurred by its directors and officers in the
performance of services as directors and officers of the Corporation; and

     E.   As a result of developments affecting the terms, scope and
availability of D & O Insurance there exists general uncertainty as to the
extent and overall desirability of protection afforded officers by such D & O
Insurance, if any, and by statutory and bylaw indemnification provisions; and

     F.   In order to induce Officer to continue to serve as an officer of the
Corporation, the Corporation has determined and agreed to enter into this
contract with Officer;

     NOW, THEREFORE, in consideration of Officer's continued service as an
officer after the date hereof, the parties hereto agree as follows:

     1.   INDEMNITY OF OFFICER.  The Corporation hereby agrees to hold harmless
and indemnify Officer to the fullest extent authorized or permitted by the
provisions of the Law, as it may be amended from time to time.



<PAGE>

     2.   ADDITIONAL INDEMNITY.  Subject only to the exclusions set forth in
Section 3 hereof, the Corporation hereby further agrees to hold harmless and
indemnify Officer:

          (a)  against any and all legal expenses (including attorneys' fees),
witness fees, judgments, fines and amounts paid in settlement actually and
reasonably incurred by Officer in connection with any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (including an action by or in the right of the Corporation) to
which Officer is, was or at any time becomes a party, or is threatened to be
made a party, by reason of the fact that Officer is, was or at any time becomes
a director, officer, employee or agent of the Corporation, or is or was serving
or at any time serves at the request of the Corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise; and

          (b)  otherwise to the fullest extent as may be provided to Officer by
the Corporation under the non-exclusivity provisions of the Bylaws of the
Corporation and the Law.

     3.   LIMITATIONS ON ADDITIONAL INDEMNITY.  No indemnity pursuant to Section
2 hereof shall be paid by the Corporation:

          (a)  except to the extent the aggregate of losses to be indemnified
thereunder exceeds the sum of such losses for which Officer is indemnified
pursuant to Section 1 hereof or pursuant to any D & O Insurance purchased and
maintained by the Corporation;

          (b)  in respect of remuneration paid to Officer if it shall be
determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

          (c)  on account of any action, suit or proceeding in which judgment is
rendered against Officer for an accounting of profits made from the purchase or
sale by Officer of securities of the Corporation pursuant to the provisions of
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or
similar provisions of any federal, state or local statutory law;

          (d)  on account of Officer's conduct which is finally adjudged to have
been knowingly fraudulent or deliberately dishonest, or to constitute willful
misconduct;

          (e)  on account of Officer's conduct which is the subject of an
action, suit or proceeding described in Section 7(c)(ii) hereof;

          (f)  on account of or arising in response to any action, suit or
proceeding (other than an action, suit or proceeding referred to in Section 8(b)
hereof) initiated by Officer or any of Officer's affiliates against the
Corporation or any officer, director or


                                       -2-
<PAGE>

stockholder of the Corporation unless such action, suit or proceeding was
authorized in the specific case by action of the Board of Directors of the
Corporation;

          (g)  on account of any action, suit or proceeding to the extent that
Officer is a plaintiff, a counter-complainant or a cross-complainant therein
(other than an action, suit or proceeding permitted by Section 3(f) hereof); or

          (h)  if a final decision by a Court having jurisdiction in the matter
shall determine that such indemnification is not lawful (and, in this respect,
both the Corporation and Officer have been advised that the Securities and
Exchange Commission believes that indemnification for liabilities arising under
the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication).

     4.   CONTRIBUTION.  If the indemnification provided in Sections 1 and 2 is
unavailable and may not be paid to Officer for any reason other than those set
forth in paragraphs (b) through (g) of Section 3, then in respect of any
threatened, pending or completed action, suit or proceeding in which the
Corporation is or is alleged to be jointly liable with Officer (or would be if
joined in such action, suit or proceeding), the Corporation shall contribute to
the amount of expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred and paid or payable by
Officer in such proportion as is appropriate to reflect (i) the relative
benefits received by the Corporation on the one hand and Officer on the other
hand from the transaction from which such action, suit or proceeding arose, and
(ii) the relative fault of the Corporation on the one hand and of Officer on the
other hand in connection with the events which resulted in such expenses,
judgments, fines or settlement amounts, as well as any other relevant equitable
considerations.  The relative fault of the Corporation on the one hand and of
Officer on the other hand shall be determined by reference to, among other
things, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent the circumstances resulting in such expenses,
judgments, fines or settlement amounts.  The Corporation agrees that it would
not be just and equitable if contribution pursuant to this Section 4 were
determined by pro rata allocation or any other method of allocation which does
not take account of the foregoing equitable considerations.

     5.   CONTINUATION OF OBLIGATIONS.

          (a)   All agreements and obligations of the Corporation contained
herein shall continue during the period Officer is a director, officer, employee
or agent of the Corporation (or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise)
and shall continue thereafter so long as Officer shall be subject to any
possible claim or threatened, pending or completed action, suit or proceeding,
whether civil, criminal or investigative, by reason of the fact that Officer was
serving the Corporation or such other entity in any capacity referred to herein.


                                       -3-
<PAGE>

          (b)   For six years after the effective time of (i) the acquisition of
the Corporation by another entity by means of any transaction or series of
related transactions (including, without limitation, any reorganization, merger
or consolidation) or (ii) the sale of all or substantially all of the assets of
the Corporation by means of any transaction or series of related transactions,
the Corporation (to the extent the Corporation is not the continuing or
surviving person of such reorganization, merger, consolidation or sale) shall
cause the acquiring, continuing or surviving corporation to (x) indemnify and
hold harmless Officer in accordance with Section 1 and 2 hereof and (y) use its
best efforts to provide officers' liability  insurance on terms substantially
similar to the terms of the Corporation's then current officers' liability
insurance policy in effect on the date thereof, or any other arrangement
reasonably satisfactory to Officer, in respect of acts or omissions occurring on
or prior to the effective time of the reorganization, merger, consolidation or
sale.

     6.   NOTIFICATION AND DEFENSE OF CLAIM.  Not later than thirty (30) days
after receipt by Officer of notice of the commencement of any action, suit or
proceeding, Officer will, if a claim in respect thereof is to be made against
the Corporation under this Agreement, notify the Corporation of the commencement
thereof; but the omission so to notify the Corporation will not relieve it from
any liability which it may have to Officer otherwise than under this Agreement.
With respect to any such action, suit or proceeding as to which Officer notifies
the Corporation of the commencement thereof:

          (a)  the Corporation will be entitled to participate therein at its
own expense;

          (b)  except as otherwise provided below, to the extent that it may
wish, the Corporation jointly with any other indemnifying party similarly
notified will be entitled to assume the defense thereof, with counsel reasonably
satisfactory to Officer.  After notice from the Corporation to Officer of its
election so as to assume the defense thereof, the Corporation will not be liable
to Officer under this Agreement for any legal or other expenses subsequently
incurred by Officer in connection with the defense thereof other than reasonable
costs of investigation or as otherwise provided below.  Officer shall have the
right to employ his or her own counsel in such action, suit or proceeding but
the fees and expenses of such counsel incurred after notice from the Corporation
of its assumption of the defense thereof shall be at the expense of Officer
unless (i) the employment of counsel by Officer has been authorized by the
Corporation, (ii) Officer shall have reasonably concluded that there may be a
conflict of interest between the Corporation and Officer in the conduct of the
defense of such action or (iii) the Corporation shall not in fact have employed
counsel to assume the defense of such action, in each of which cases the fees
and expenses of Officer's separate counsel shall be at the expense of the
Corporation.  The Corporation shall not be entitled to assume the defense of any
action, suit or proceeding brought by or on behalf of the Corporation or as to
which Officer shall have made the conclusion provided for in (ii) above; and

          (c)  the Corporation shall not be liable to indemnify Officer under
this Agreement for any amounts paid in settlement of any action or claim
effected without its


                                       -4-

written consent.  The Corporation shall be permitted to settle any action except
that it shall not settle any action or claim in any manner which would impose
any penalty, out-of-pocket liability, or limitation on Officer without Officer's
written consent.  Neither the Corporation nor Officer will unreasonably withhold
its or his or her consent to any proposed settlement.

     7.   ADVANCEMENT AND REPAYMENT OF EXPENSES.

          (a)  In the event that Officer employs his or her own counsel pursuant
to Section 6(b)(i) through (iii) above, the Corporation shall advance to
Officer, prior to any final disposition of any threatened or pending action,
suit or proceeding, whether civil, criminal, administrative or investigative,
any and all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding within ten (10)
days after receiving copies of invoices presented to Officer for such expenses.

          (b)  Officer agrees that Officer will reimburse the Corporation for
all reasonable expenses paid by the Corporation in defending any civil or
criminal action, suit or proceeding against Officer in the event and only to the
extent it shall be ultimately determined by a final judicial decision (from
which there is no right of appeal) that Officer is not entitled, under the
provisions of the Law, the Bylaws, this Agreement or otherwise, to be
indemnified by the Corporation for such expenses.

          (c)  Notwithstanding the foregoing, the Corporation shall not be
required to advance such expenses to Officer if Officer (i) commences any
action, suit or proceeding as a plaintiff unless such advance is specifically
approved by a majority of the Board of Directors or (ii) is a party to an
action, suit or proceeding brought by the Corporation and approved by a majority
of the Board which alleges willful misappropriation of corporate assets by
Officer, disclosure of confidential information in violation of Officer's
fiduciary or contractual obligations to the Corporation, or any other willful
and deliberate breach in bad faith of Officer's duty to the Corporation or its
stockholders.

     8.   ENFORCEMENT.

          (a)  the Corporation expressly confirms and agrees that it has entered
into this Agreement and assumed the obligations imposed on the Corporation
hereby in order to induce Officer to continue as an officer of the Corporation,
and acknowledges that Officer is relying upon this Agreement in continuing in
such capacity.

          (b)  In the event Officer is required to bring any action to enforce
rights or to collect moneys due under this Agreement and is successful in such
action, the Corporation shall reimburse Officer for all of Officer's reasonable
fees and expenses in bringing and pursuing such action.


                                       -5-

     9.   SUBROGATION.  In the event of payment under this agreement, the
Corporation shall be subrogated to the extent of such payment to all of the
rights of recovery of Officer, who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable the
Corporation effectively to bring suit to enforce such rights.

     10.  NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on Officer by this
Agreement shall not be exclusive of any other right which Officer may have or
hereafter acquire under any statute, provision of the Corporation's Certificate
of Incorporation or Bylaws, agreement, vote of stockholders or directors, or
otherwise, both as to action in his or her official capacity and as to action in
another capacity while holding office.

     11.  SURVIVAL OF RIGHTS.  The rights conferred on Officer by this Agreement
shall continue after Officer has ceased to be a director, officer, employee or
other agent of the Corporation or such other entity and shall inure to the
benefit of Officer's heirs, executors and administrators.

     12.  SEPARABILITY.  Each of the provisions of this Agreement is a separate
and distinct agreement and independent of the others, so that if any or all of
the provisions hereof shall be held to be invalid or unenforceable to any extent
for any reason, such invalidity or unenforceability shall not affect the
validity or enforceability of the other provisions hereof or the obligation of
the Corporation to indemnify Officer to the full extent provided by the Bylaws
or the Law, and the affected provision shall be construed and enforced so as to
effectuate the parties' intent to the maximum extent possible.

     13.  GOVERNING LAW.  This Agreement shall be interpreted and enforced in
accordance with the internal laws of the State of Delaware.

     14.  BINDING EFFECT.  This Agreement shall be binding upon Officer and upon
the Corporation, its successors and assigns, and shall inure to the benefit of
Officer, his or her heirs, personal representatives and assigns and to the
benefit of the Corporation, its successors and assigns.

     15.  AMENDMENT AND TERMINATION.  No amendment, modification, termination or
cancellation of this Agreement shall be effective unless set forth in a writing
signed by both parties hereto.

     16.  NO EMPLOYMENT OR SERVICE CONTRACT.  Nothing in this Agreement shall
confer upon Officer any right to continue in the service of the Corporation for
any period of specific duration or interfere with or otherwise restrict in any
way the rights of the Corporation or Officer which rights are hereby expressly
reserved by each, to terminate Officer's service at any time for any reason
whatsoever, with or without cause.
