                                  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 endoscopic cameras 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, as
well as patient demand. 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. All 510(k) clearances
to market necessary for Series 8000 commercialization have been received, with
expected commercial availability later this year. The StereoSite systems are
under development, have not been cleared to market in the U.S. by the U.S. Food
and Drug Administration ("FDA") and are not commercially available. The Company
anticipates filing a required 510(k) pre-market notification for the processor
component of the HMD for the StereoSite system in third quarter 1997. All other
required 510(k) clearances to market for the StereoSite system have been
received. 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,
 
                                       4
<PAGE>
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 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. If an initial public
offering is not completed by June 30, 1997, the price will be $6.67 per share.
 
    Since February 1997, Vista Medical's CardioThoracic Surgery division has
exhibited the Series 8000 at two major cardiothoracic surgery meetings in the
U.S. and at the World Congress on Minimally Invasive Cardiac Surgery in Paris.
Surgeons attending these conferences expressed interest in the potential growth
of minimally invasive surgeries and the importance of enabling technologies such
as visualization. At these conferences, hundreds of surgeons participated in a
hands-on demonstration of the Series 8000, expressed interest and requested
additional information.

                                  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 MAY CONTAIN FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS MAY DIFFER SIGNIFICANTLY
FROM THE RESULTS DISCUSSED IN SUCH 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 March 31, 1997, the Company had incurred
cumulative net losses of $16.9 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.
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 its operations through 1998.
If, at or prior to such time, 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. In international markets,
however, regulatory clearance or approval is required before the system can be
widely marketed. 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 as efficacious as 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 four direct
(Company employee) sales representatives and 30 independent sales
representatives. The Company is in the process of hiring up to eight 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, and
changes in intended use of, medical devices also are subject to FDA review and
clearance or approval. The FDA regulates the research, testing, manufacture,
safety, effectiveness, 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 or
suspension 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., establishment
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 market the device upon receipt of an FDA order
determining such a device substantially equivalent to a predicate device. 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.
 
                                       10
<PAGE>
    Following submission of the 510(k) notification, the manufacturer or
distributor may not place the device into commercial distribution until an FDA
substantial equivalence order permitting the marketing of a device is received
by the person who submitted the 510(k) notification. 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 require 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 bench 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. However, the FDA can disagree with a non-significant risk
device finding.
 
    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 new 510(k), PMA or PMA supplement 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 or a new indication for 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 new
510(k), PMA or PMA supplement.
 
    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.

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, 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; changes
in third-party payment guidelines; 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,
 
                                       12
<PAGE>
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."
 
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.
 
                                       13
<PAGE>
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. 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 May 31, 1997, the Company had exclusive
ownership rights to seven issued United States patents, 10 pending United States
patent applications and eight pending foreign applications covering various
aspects of its devices and systems. Furthermore, as of the same date, the
Company had exclusive rights in the medical field to four issued United States
patents, one pending United States patent application, three issued foreign
patents and nine 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,
 
                                       14
<PAGE>
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 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
 
                                       15
<PAGE>
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."
 
    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 in the medical
field 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. 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 (or, under certain
circumstances, the license terminates) 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. The Company has not entered into any
employment contracts or arrangements with any of its employees. 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
 
                                       16
<PAGE>
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, procedures
and controls, and to expand, train, motivate and manage its work force. The
Company is in the final stages 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 71.1% 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."
 
                                       17
<PAGE>
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 9,139,000 shares of Common Stock, including shares
issued or issuable upon the exercise of vested options and warrants outstanding
as of May 31, 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 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 May 31, 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 9,039,000
shares will be eligible for sale 180 days after the date of this Prospectus; the
remaining 100,000 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 foreseeable
future. See "Dividend Policy."
 
                                       18
<PAGE>
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 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 endoscopic cameras 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, as
well as patient demand. 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. All 510(k) clearances
to market necessary for Series 8000 commercialization have been received, with
expected commercial availability later this year. The StereoSite systems are
under development, have not been cleared to market in the U.S. by the U.S. Food
and Drug Administration ("FDA") and are not commercially available. The Company
anticipates filing a required 510(k) pre-market notification for the processor
component of the HMD for the StereoSite system in third quarter 1997. All other
required 510(k) clearances to market for the StereoSite system have been
received. 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. If an initial
public offering is not completed by June 30, 1997, the price will be $6.67 per
share.
 
    Since February 1997, Vista Medical's CardioThoracic Surgery division has
exhibited the Series 8000 at two cardiothoracic surgery meetings in the U.S. and
at the World Congress on Minimally Invasive Cardiac Surgery in Paris. Surgeons
attending these conferences expressed interest in the potential growth of
minimally invasive surgeries and the importance of enabling technologies such as
visualization. At these conferences, hundreds of surgeons participated in a
hands-on demonstration of the Series 8000, expressed interest and requested
additional information.
 
    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 (760) 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 $28,595,000
($32,989,250 if the Underwriters' over-allotment option is exercised in full),
assuming a public offering price of $9.00 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.
 
    From the anticipated $28.6 million net proceeds of this Offering, the
Company intends to use approximately $9.5 million to fund product introductions,
approximately $5.9 million for sales and marketing activities, approximately
$4.3 million for research and development, approximately $2.3 million for the
acquisition of capital equipment for manufacturing scale-up and the balance of
approximately $6.6 million for working capital and general corporate purposes.
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 agreements with other
companies, the availability of additional financing and other factors. 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 its operations through 1998. 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 March 31, 1997 was $9,645,187,
or $1.04 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 $9.00 per share (the mid-point of the range set forth on the
front cover), and after deducting underwriting discounts and commissions and
estimated offering expenses payable by the Company, the Company's net tangible
book value as of March 31, 1997 would have been $38,240,187 or $2.99 per share
of Common Stock. This represents an immediate increase in net tangible book
value per share of Common Stock of $1.95 to existing stockholders and immediate
dilution in net tangible book value of $6.01 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 March 31, 1997, options to purchase
1,282,676 shares of Common Stock were outstanding at a weighted average exercise
price of approximately $0.54 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. As of March 31, 1997, the Company had also (i) issued
warrants to Heartport to purchase 100,000 shares of Common Stock at an exercise
price equal to the initial public offering price of the Common Stock offered
hereby or, if not completed by June 30, 1997, with an exercise price of $6.67
per share and (ii) 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
March 31, 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" and "Description of Capital Stock."

                    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 endoscopic cameras and
related surgical instruments and accessories.
 
    The Company has generated minimal revenues, principally from the sale of its
endoscopic cameras, and has been unprofitable since its formation in July 1993.
For the period from the Company's formation to March 31, 1997, the Company has
incurred cumulative net losses of approximately $16.9 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 required regulatory approval
of products will continue to be obtained in a timely manner, if at all.
 
    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, 1996 and at March 31, 1997, the Company had 11, 21, 49 and 59
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
recorded 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 plans to adopt a per-procedure pricing strategy for the Series
8000 in the United States market. This strategy, designed to accelerate adoption
of the Series 8000, would require a payment to the Company every time the Series
8000 is used in a procedure. Therefore, revenues are directly related to usage.
In return, customers would receive an integrated equipment and service package,
including installation, in-service training, on-going technical support and
system upgrades, for a single charge which can be clearly related to a specific
procedure. The Company believes that adoption of such a strategy, based upon a
service contract rather than an upfront capital payment, will allow more rapid
penetration of the available market. The Company intends to amortize the cost of
the Series 8000 over the term of the service contract. Under the per-procedure
pricing strategy, the Company is required to allocate adequate capital resources
to fund such investment, as the customer does not purchase the system with an
upfront capital payment.
 
    This discussion may contain forward-looking statements that involve risks
and uncertainties. The Company's actual results may differ significantly from
the results discussed in such forward-looking statements. Factors that might
cause such a difference include, but are not limited to, those discussed in
"Risk Factors."

RESULTS OF OPERATIONS
 
  QUARTERS ENDED MARCH 31, 1996 AND 1997
 
    SALES.  The Company had revenues from product sales of $241,000 in the
quarter ended March 31, 1996 and $829,000 in the quarter ended March 31, 1997.
The increase was primarily attributable to the sales of surgical instruments and
sutures for which the Company acquired distribution rights during the second
half of 1996 and to the increased sales of the Company's endoscopic cameras to
new and existing customers. Sales to individual customers exceeding 10% or more
of revenues for the three months ended March 31, 1996 and 1997 were as follows:
for the three months ended March 31, 1996, three customers accounted for 62%,
20% and 12% of revenues; for the three months ended March 31, 1997, four
customers accounted for 27%, 18%, 17% and 10% of revenues, three of whom were
greater than 10% customers for the three months ended March 31, 1996. The
Company believes that the loss of any of these customers would not have a
material adverse effect on the Company's business, operating results or
financial condition and that concentration of revenues to individual customers
will likely decrease in future periods as the Company introduces new products.
 
    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 $184,000 for the quarter ended March 31, 1996 and
$826,000 for the quarter ended March 31, 1997. The increase in these expenses
was related to the growth in revenue between the periods and to investment in
manufacturing infrastructure the Company is making to accommodate the scale-up
for new product introductions in 1997.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
consist 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 $533,000 for the quarter ended
March 31, 1996 and $1,514,000 for the quarter ended March 31, 1997. The increase
was primarily attributable to increases in staffing, contract research and
development expense and consulting fees related to development, prototyping and
evaluation of future products.
 
    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 were $313,000 for the quarter
ended March 31, 1996 and $745,000 for the quarter ended March 31, 1997. The
increase was primarily attributable to increases in staffing and related
expenses, professional and consulting fees in connection with marketing programs
related to new products and commissions.
 
    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 $399,000 for the quarter ended March
31, 1996 and $1,164,000 for the quarter ended March 31, 1997. The increase was
primarily attributable to increases in staffing and related expenses associated
with development of the Company's administrative infrastructure, increases in
legal and professional fees related to patents and other business development
efforts, and the amortization of deferred compensation. The Company recorded
noncash deferred compensation of $743,000 in connection with stock options
granted in January and February 1997. The unamortized balance of the deferred
compensation will be expensed over the five-year vesting periods of the options
and, therefore, will continue to impact the Company's operating results through
2001.
 
                                       27
<PAGE>
    INTEREST INCOME.  Interest income was $34,000 in the quarter ended March 31,
1996 and $102,000 in the quarter ended March 31, 1997, with the increase due to
increasing average investment balances.
 
  YEARS ENDED DECEMBER 31, 1994, 1995 AND 1996
 
    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 endoscopic cameras by the Company. The
increase in revenue from 1995 to 1996 was attributable to the increased sales of
the Company's endoscopic 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. For the years ended December 31, 1994, 1995 and 1996, the same
customer accounted for 18%, 85% and 25% of revenues, respectively. The Company
believes that the loss of any of these customers would not have a material
adverse effect on the Company's business, operating results or financial
condition and that concentration of revenues to individual customers will likely
decrease in future periods as the Company introduces new products.
 
    COST OF SALES.  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 EXPENSES.  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 acquired in-process
research and development, increased staffing and contract research and
development expense performed by third parties. The increase in research and
development expenses from 1995 to 1996 was attributable to significant increases
in staffing, contract 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 increased from
$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.
 
                                       28
<PAGE>
    GENERAL AND ADMINISTRATIVE EXPENSES.  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
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 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.
 
    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 unrelated to the Company's main products and markets. The
license to Urohealth was a unique, non-recurring transaction that involved a
license of only that component of the Company's technology that it did not want
to pursue. For this reason, the license fees were treated as non-operating
income. Prior to 1996, the Company had no license income. No other technology is
being developed with the purpose of being licensed and the Company does not
anticipate any future licensing arrangements of any of its core technology for
medical applications.
 
    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 March 31, 1997, the Company had approximately $5,844,000 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 Kaiser Aerospace 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 $23,055,000, of which
$3,004,000 was used to repay advances from Kaiser Aerospace (with the remaining
$2,375,000 in outstanding advances being satisfied by the issuance of Series A-1
Preferred Stock).
 
    Net cash used in operating activities was approximately $2,288,000,
$3,567,000 and $6,937,000 for 1994, 1995 and 1996, respectively, and $1,603,000
and $4,123,000 for the quarters ended March 31, 1996 and 1997, respectively. The
increase in net cash used from operating activities each year and for the
quarterly periods has resulted primarily from increasing net losses during such
periods and investments in inventories associated with expansion of the
Company's product line.
 
                                       29
<PAGE>
    Net cash used in investing activities was approximately $94,000, $298,000
and $1,239,000 for 1994, 1995 and 1996, respectively, and $92,000 and $353,000
for the quarters ended March 31, 1996 and 1997, respectively. The increase in
net cash used in investing activities each year and for the quarterly periods
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 and $3,000 and $36,000 for the quarters
ended March 31, 1996 and 1997, respectively. The increase in cash flows from
financing activities resulted primarily from increased advances from Kaiser
Aerospace in 1994 and primarily from the private sale of common and preferred
stock in 1995 and 1996. The increase in the quarter ended March 31, 1997 from
that of the quarter ended March 31, 1996 was due to increased exercises of
options to purchase common stock.
 
    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, and $92,000 and $353,000 for the quarters ended March 31,
1996 and 1997, 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 March 31, 1997, the Company had commitments for capital
expenditures of approximately $1,250,000 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 is currently negotiating with a lender to secure a $10.0 million
credit line. There can be no assurances that the Company will be successful in
negotiating such a credit line on favorable terms, if at all.
 
    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 its
operations through 1998. Certain circumstances, however, including slow rate of
market acceptance of the Company's products, the Company's inability to scale up
manufacturing or delay in further regulatory approvals, 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, debt 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 endoscopic cameras and
related surgical instruments and accessories. Vista Medical's visualization and
information systems bring together the 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. The Company was founded as a
wholly-owned subsidiary of Kaiser Aerospace in July 1993, and became an
independent entity in July 1995 with the addition of several venture capital
funds as investors.
 
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.
 
                                       31
<PAGE>
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 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 restricted visibility through the minimal incisions
currently used. While new retractor systems are being introduced to open the
incision and therefore improve the surgeon's access and ability to visualize the
anatomy directly, restricted visibility, particularly for more complex cases,
remains an issue. In addition, the objective of minimizing the incision size
("keyhole" access) to reduce trauma can only be achieved effectively with
visualization, as has been demonstrated in other minimally invasive
applications. As a result of these factors, the development of cardiothoracic
MIM will require enhanced visualization, as well as specialized instruments and
surgeon training in the new 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
 
                                       32
<PAGE>
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 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
 
                                       33
<PAGE>
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 implementing a
per-procedure pricing strategy. This strategy would offer the Series 8000 on a
rental basis and 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"), 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 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.
 
                                       34
<PAGE>
    - 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.
 
    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. Kaiser's original know-how and
technical knowledge have been transferred to the Company pursuant to the
development agreement with Kaiser Electro-Optics, Inc. ("Kaiser
Electro-Optics"), a subsidiary of Kaiser Aerospace. The Company has done
significant additional development work, and has proprietary rights, in the
surgical HMD design. The Vista Medical HMD, which the Company believes is 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 proprietary, 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
 
                                       35
<PAGE>
3-D endoscopic optical system employed by Vista Medical was originally developed
and patented by a 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 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.

significant portion of the Company's revenues. The Company's endoscopic camera
is also referred to as a three-chip camera. "Three-chip" refers to the
allocation of a chip to each of the primary colors--red, green and blue. This
results in superior color reproduction relative to a standard "single chip"
camera, where one chip serves for all three primary colors.
 
    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
 
                                       38

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 cardiothoracic 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.
 
   
    In connection with entering into the co-promotion agreement, Medtronic made
a $10 million equity investment in the Company and received 2,000,000 shares of
Series C Preferred Stock, which will be automatically converted into 1,500,000
shares of Common Stock in connection with this Offering. In addition, Vista
Medical and Medtronic entered into a Supplemental Rights Agreement in connection
with entering into the co-promotion agreement, pursuant to which Medtronic
received a first offer purchase right in certain proposed transactions and a
right to designate an observer to attend meetings of the Board of Directors.
Each of these rights terminate upon the closing of the Offering.
    
 
                                       39
<PAGE>
  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. If an
initial public offering is not completed by June 30, 1997, the price will be
$6.67 per share.
 
  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 hired 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.
 
  KAISER AEROSPACE
 
    The Company was founded as a wholly-owned subsidiary of Kaiser Aerospace in
July 1993, and became an independent entity in July 1995 with the addition of
several venture capital funds as
 
                                       40
<PAGE>
investors. Substantially all of the shares originally issued to Kaiser Aerospace
were subsequently transferred to Foster City Partners, a partnership which
includes senior executives of Kaiser Aerospace, in June 1996. Foster City
Partners remained a significant stockholder participating pro-rata in a further
investment round in July 1996. See "Certain Transactions."
 
    In July 1995, the Company entered into a Technology Strategic Alliance:
Memorandum of Understanding (the "Technology Strategic Alliance") and a
Manufacturing Supply Agreement with Kaiser Electro-Optics, a subsidiary of
Kaiser Aerospace. The Technology Strategic Alliance provides that the Company
and Kaiser Electro-Optics will cooperate in joint development programs related
to the HMD as appropriate to be negotiated on an arms-length and
project-by-project basis for an unspecified term. The Company contracts with
Kaiser Electro-Optics for development and manufacturing services related to the
Company's HMD, including initial production quantities for the HMD. The
Manufacturing Supply Agreement provides that Kaiser Electro-Optics will be the
Company's preferred supplier for a three-year period for not less than 75% of
its requirements for the optical subassembly of the Company's HMD, provided that
pricing and other terms are competitive and mutually agreed upon.
 
  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 begin training programs in
the third quarter of 1997 and expects to be able to train up to 250 surgeons on
an annual basis. VCS 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."
 
                                       41
<PAGE>
    CLINICAL EVALUATION.  VCS and VHNS product lines have been developed with
frequent input from the Clinical Advisory Boards of each division. This
evaluation phase will 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.
 
    Since February 1997, Vista Medical's CardioThoracic Surgery division has
exhibited the Series 8000 at two major cardiothoracic surgery meetings in the
U.S. and at the World Congress on Minimally Invasive Cardiac Surgery in Paris.
Surgeons attending these conferences expressed interest in the potential growth
of minimally invasive surgeries and the importance of enabling technologies such
as visualization. At these conferences, hundreds of surgeons participated in a
hands-on demonstration of the Series 8000, expressed interest and requested
additional information.
 
    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 four direct and 30 independent representatives and
is in the process of hiring up to eight additional direct sales people to
support the introduction of the Series 8000. In addition, Medtronic will
co-promote the Series 8000 in conjunction with Medtronic's own proprietary
products for minimally invasive cardiac surgery in the U.S. and Canada. 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.
 
    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 first quarter 1998 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
 
                                       42
<PAGE>
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, 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, and
changes in intended use of, medical devices also are subject to FDA review and
clearance or approval. The FDA regulates the research, testing, manufacture,
safety, effectiveness, 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.
 
                                       43
<PAGE>
Noncompliance with applicable requirements can result in failure of the
government to grant pre-market clearance or approval for devices, withdrawal or
suspension 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., establishment
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 market the device upon receipt of an FDA order
determining such a device substantially equivalent to a predicate device. 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 an FDA
substantial equivalence order permitting the marketing of a device is received
by the person who submitted the 510(k) notification. 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 require 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.
 
    The Company has received 510(k) clearance to market the following product
lines in the United States: (i) 3-D video endoscope (April 1997); (ii) mini
cameras (April 1997); (iii) illumination system (April 1997); (iv) head mounted
display (September 1996); (v) additional cardiothoracic indications for the 3-D
scope (July 1996); (vi) sinus telescopes (October 1995); (vii) video endoscope
with zoom (January 1995); (viii) stereo viewing system (November 1994); (ix)
dental camera (November 1994); (x) three-chip (endoscopic) video camera (June
1994); and (xi) 3-D scope (December 1992). All 510(k) clearances to market
necessary for Series 8000 commercialization have been received. The Company
anticipates filing a required 510(k) pre-market notification for the processor
component of the HMD for the StereoSite systems in third quarter 1997. All other
required 510(k) clearances to market for the StereoSite system have been
received. Internationally, the Company's three-chip video camera and the
 
                                       44
<PAGE>
zoom endoscope have qualified for the CE mark under the Electromagnetic
Compatibility Directive for sale in Europe.
 
    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 bench 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. However, the FDA can disagree with a
non-significant risk device finding.
 
    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 new 510(k), PMA or PMA supplement 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 or a new indication for 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 new
510(k), PMA or PMA supplement.
 
    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. 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. See "--Strategic
Alliances--Medtronic."
 
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 May 31, 1997, the Company had exclusive
ownership rights to seven issued United States patents, 10 pending United States
patent applications and eight pending foreign applications covering various
aspects of its devices and systems. Furthermore, as of the same date, the
Company had exclusive rights in the medical field to four issued United States
patents, one pending United States patent application, three issued foreign
 
                                       45
<PAGE>
patents and nine 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 has rights in the following trademarks: 3D
Scope-Registered Trademark-, Design of Cone and Vista Medical Technologies &
Design. In addition, the Company has applied to register the following
trademarks: 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. In September
1995, McKinley granted to the Company a perpetual, exclusive, worldwide license
in the medical field 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. 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 (or, under certain
circumstances, the license terminates) 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. 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.
 
    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
 
                                       46
<PAGE>
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 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:

(1) In accordance with the terms of the 1995 Stock Option Plan under which these
    options were granted, 50% of the shares subject to each 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 vest if
    employee is terminated without cause within two years of the merger or asset

(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
 
                                       54
<PAGE>
    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; however, any shares purchased upon
    exercise may be subject to rights of repurchase on the part of the Company
    which lapse at various times over the next five years.
 
(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
 
    The Company has not entered into any employment contracts or arrangements
with any of its Named Executive Officers.
 
    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."
 
                                       55
<PAGE>
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, as amended, (the
"Plan") which was adopted in February 1997 and amended in March and May 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 300,000 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
 
                                       56
<PAGE>
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.
 
    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
 
                                       57
<PAGE>
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
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. The initial offering period
under the Purchase Plan will commence on the effective date of a Registration
Statement on Form S-8 covering the shares of Common Stock issuable under the
Purchase Plan (which the Company intends to file on the effective date of this
Offering) and will terminate no later than 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
 
                                       58
<PAGE>
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 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.

    Vista Medical was founded as a wholly-owned subsidiary of Kaiser Aerospace
in July 1993. Kaiser Aerospace financed the initial operations of the Company
through cash advances aggregating $5.4 million.
 
    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. 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. See "Business
- -- Strategic Alliances -- Kaiser Aerospace." 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

    In July 1995, the Company entered into a Technology Strategic Alliance and a
Manufacturing Supply Agreement with Kaiser Electro-Optics, a subsidiary of
Kaiser Aerospace. The Technology Strategic Alliance provides that the Company
and Kaiser Electro-Optics will cooperate in joint development programs related
to the HMD as appropriate to be negotiated on an arms-length and
project-by-project basis for an unspecified term. The Company contracts with
Kaiser Electro-Optics for development and manufacturing services related to the
Company's HMD, including initial production quantities for the HMD. The
Manufacturing Supply Agreement provides that Kaiser Electro-Optics will be the
Company's preferred supplier for a three-year period for not less than 75% of
its requirements for the optical subassembly of the Company's HMD, provided that
pricing and other terms are competitive and mutually agreed upon.
 
    In July 1996, the Company raised approximately $4.3 million in cash from
Foster City Partners, various venture capital funds, including funds which are
principal stockholders of the Company and/or affiliated with directors of the
Company, and other accredited investors in a private placement of its Series B
Preferred Stock. The Company repaid its indebtedness to certain of the venture
capital funds by permitting such funds to cancel approximately $0.8 million of
indebtedness owed by the Company as consideration for shares of Series B
Preferred Stock.
 
    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 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. The
Company's acquisition of the assets of AST was accounted for using the purchase
method of accounting with the assets being recorded at their estimated fair
values at the date of acquisition.
 
    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 50%
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 and received 2,000,000 shares of Series
C Preferred Stock, which will be automatically converted into 1,500,000 shares
of Common Stock in connection with this Offering. In addition, Vista Medical and
Medtronic entered into a Supplemental Rights Agreement in connection with
entering into the co-promotion agreement, pursuant to which Medtronic received a
first offer purchase right in certain proposed transactions and a right to
designate an observer to attend meetings of the Board of Directors. Each of
these rights terminate upon the closing of the Offering.
    
 
    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.

    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

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

                          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 12,797,528
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 May 31, 1997, there were 9,297,528 shares of Common Stock outstanding and
held of record by approximately 74 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.
If an initial public offering is not completed by June 30, 1997, the exercise
price will be $6.67 per share. 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."

    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
 
                                       65
<PAGE>
demand registration rights, and the Company is required to use its best efforts
to effect such registration, 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.
 
                                       66
<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.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of this Offering, the Company will have 12,797,528 shares of
Common Stock outstanding (assuming no exercise of options or other convertible
securities or issuances of Common Stock subsequent to March 31, 1997). 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 9,298,000 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
7,548,000 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 7,514,000 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 9,489,000 shares of Common Stock (including shares
issued or issuable upon the exercise of vested options and warrants outstanding
as of May 31, 1997) will become available for sale in the public market; the
remaining 100,000 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, 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
 
                                       68
<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
the period ended December 31, 1996 in conformity with generally accepted
accounting principles.

                               DECEMBER 31, 1996
 
 (INFORMATION SUBSEQUENT TO DECEMBER 31, 1996 AND PERTAINING TO MARCH 31, 1997
 
    AND THE THREE MONTH PERIODS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
 
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. In July 1995, equity
securities were sold to outside investors, thereby reducing Kaiser Aerospace's
ownership of the Company. (See Note 6.)
 
  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.
 
  INTERIM FINANCIAL INFORMATION (UNAUDITED)
 
    The financial statements for the three month periods ended March 31, 1996
and 1997 include all adjustments (consisting only of normal recurring
adjustments) which management considers necessary for a fair statement of the
financial position at such dates and the operating results and cash flows for
the periods. Results for interim periods are not necessarily indicative of
results for the entire year or any future periods.
 
  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

 (INFORMATION SUBSEQUENT TO DECEMBER 31, 1996 AND PERTAINING TO MARCH 31, 1997
 
    AND THE THREE MONTH PERIODS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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.
 
  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 uncollectible 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

    AND THE THREE MONTH PERIODS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
 
1.  ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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.
 
  NEW ACCOUNTING STANDARD
 
    In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, EARNINGS PER SHARE, which is required to be adopted on December 31,
1997. At that time, the Company will be required to change the method currently
used to compute earnings per share and to restate all prior periods. Under the
new requirements for calculating primary earnings per share, the dilutive effect
of stock options will be excluded. The impact of Statement 128 on the
calculation of fully diluted earnings per share, if applicable, for these
periods is not expected to be material.
 
  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 March 31, 1997, as adjusted for the conversion of
preferred stock, is disclosed in the accompanying balance sheet.

5. LICENSE INCOME (CONTINUED)
In exchange for the license, the Company received $1,000,000 in cash and 110,000
shares of common stock valued at $693,000. The common stock received is
restricted stock of a publicly traded company with restrictions on the sale of
the stock for two years from the date of the agreement in accordance with the
provisions of Rule 144 under the Securities Act of 1933, as amended. No other
technology is being developed with the purpose of being licensed and the Company
does not anticipate any future licensing arrangements of any of its core
technology for medical applications. The license to Urohealth Systems, Inc.
("Urohealth") was a unique, non-recurring transaction that involved a license of
only that component of the Company's technology that it did not want to pursue.
For this reason, the license fees were treated as non-operating income. The
Company has recorded these shares at their estimated fair value to reflect the
trading restrictions. The licensed technology and patent rights were obtained by
the Company through a perpetual license and royalty agreement with an officer of
the Company. In connection with the license agreement with Urohealth, the
Company amended an existing license agreement with the officer to make its terms
consistent with the licensing agreement with Urohealth in exchange for $200,000.

6. STOCKHOLDERS' EQUITY (CONTINUED)
    Each share of the convertible preferred stock is convertible at the option
of the holder into three quarters of a share of common stock. Conversion is
mandatory upon the closing of an underwritten public offering in which the
aggregate gross proceeds received by the Company are at least $15,000,000 with a
per share price of no less than $5.00. The conversion ratio is subject to
certain anti dilution adjustments, and the holders of each share of Series A-1,
B and C convertible preferred stock are entitled to one vote for each share of
common stock into which it would convert. Series A-3 convertible preferred stock
has no voting rights until the Series A-3 convertible preferred stock converts
to common stock.
 
    The holders of convertible preferred stock are entitled to receive
non-cumulative dividends when and as declared by the Board of Directors at the
rate of 8% per annum. No dividends have been declared to date.
 
  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 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 recorded $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.

and 232,335 options were available for future grant. At March 31, 1997, 195,309
options to purchase common shares were vested and 1,537,324 options were
available for future grant.
 
    The weighted-average fair value of options granted during the year ended
December 31, 1996 and the three months ended March 31, 1997 was $0.09 and $0.76,
respectively. The weighted-average remaining contractual life at December 31,
1996 and March 31, 1997 is 9.24 and 9.04 years, respectively.
 
    Adjusted pro forma information regarding net income is required by SFAS 123,
and has been determined as if the Company had accounted for its employee stock
options under the fair value method of that Statement. The fair value for these
options was estimated at the date of grant using the "minimal value" method for
option pricing with the following weighted-average assumptions: risk-free
interest rate range of 5.5% to 6.0%; dividend yield of 0%; and a
weighted-average expected life of the option of 2.5 to 5 years.
 
    For purposes of adjusted pro forma disclosures, the estimated fair value of
the options is amortized to expense over the options' vesting period. The effect

7. INCOME TAXES
 
    Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets as of December 31, 1996 are shown below. A
valuation allowance has been recognized to offset the deferred tax assets, as
realization of such assets is uncertain.

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
 
    Kaiser Aerospace financed the initial operations of the Company through cash
advances. In 1995 upon the closing of the Series A convertible preferred stock,
total advances by Kaiser Aerospace aggregated $5,379,000 which were settled in
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
agreement with a Kaiser Aerospace Subsidiary for the development and
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,
$1,205,000 and $259,310 for the years ending December 31, 1995 and 1996, and the
three months ended March 31, 1997, respectively. At December 31, 1996 and March
31, 1997, the Company had approximately $1,335,000 and $1,641,000 in purchase
commitments to Kaiser under these agreements.
 
9. SUBSEQUENT EVENTS

  REGISTRATION STATEMENT
 
    In January 1997, the Board of Directors approved filing a registration
statement with the Securities and Exchange Commission to sell 3,500,000 shares
of the Company's Common Stock to the public. If the Offering is consummated
under the proposed terms, the Company's outstanding shares of Series A, B and C
convertible preferred stock will automatically convert into shares of its Common
Stock. This conversion has been reflected in the accompanying pro forma
stockholders' equity as of March 31, 1997.
 
  1997 STOCK OPTION PLAN/ STOCK ISSUANCE PLAN
 
    In February 1997, the Company adopted the 1997 Stock Option Plan/Stock

Plan and no further options will be granted under the 1995 Plan.
 
  1997 EMPLOYEE STOCK PURCHASE PLAN
 
    In February 1997, the Company adopted the 1997 Employee Stock Purchase Plan
( the "Purchase Plan") and reserved 200,000 shares for issuance, thereunder. The
Purchase Plan permits eligible employees of the Company to purchase shares of
Common Stock, at semi-annual intervals, through periodic payroll deductions.
Payroll deductions may not exceed 10% of the participant's base salary, and the
purchase price per share will not be less than 85% of the lower of the fair
market value of the common stock at either the beginning or the end of the
semi-annual intervals.
 
  NEW AGREEMENTS
 
    In February 1997, the Company entered into an agreement with Heartport, Inc.
whereby the Company will sell four visualization and information systems used
for minimally invasive cardiothoracic surgery for use in Heartport's training
centers. In connection with the agreement the Company issued a warrant to
purchase up to 100,000 shares of common stock, exercisable until March 31, 2001
for a price per share equal to the initial public offering price. If an initial
public offering is not completed by June 30, 1997, the price will be $6.67 per
share. The Company will record a charge to cost of sales for the value of the
warrant upon shipment of the units.
 
    In February 1997, the Company entered into an agreement whereby the Company
will receive an exclusive worldwide license to certain software, documentation
and trademarks of GDE Systems, Inc. In connection with the agreement, the
Company will issue to GDE Systems, Inc. $250,000 of the Company's common stock
valued at the initial public offering price. The Company is required to pay
future minimum royalties of $250,000 payable by December 31, 1998.

</TABLE>
 
    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.
 
    In connection with the Offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover syndicate short positions
created in connection with the Offering. Stabilizing transactions consist of
certain bids or purchases for the purposes of preventing or retarding a decline
in the market price of the Common Stock; and syndicate short positions involve
the sale by the Underwriters of a greater number of shares of Common Stock than
they are required to purchase from the Company in 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; and these activities, if commenced, may be discontinued at any
time. These transactions may be effected on the Nasdaq National Market, in the
over-the-counter market or otherwise.
 
    The Common Stock has been approved for listing 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.

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
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.
 
                                      II-1
<PAGE>
    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 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.

    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.
 
    The undersigned hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
    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.

     12.3.   DISTRIBUTOR shall have twenty (20) days after written notice
             specifying a breach of this Agreement to cure such breach.  If,
             under the circumstances then current, it would appear that any
             breach is final, or cannot be cured, ASTC may terminate the
             Agreement immediately for cause by giving notice to this effect.

     12.4.   Either ASTC or DISTRIBUTOR may terminate this Agreement in the

             during the term this Agreement is in effect.  Termination under
             this provision shall be effective twenty (20) days following
             written notice to that effect.

     12.5.   DISTRIBUTOR may terminate this Agreement immediately for just cause
             should ASTC breach any provision of this Agreement, provided that

             breach within twenty (20) days following written notice of
             DISTRIBUTOR's intention to terminate on account of such breach.

     12.6.   Upon termination of this Agreement for whatever reason, any claims

             to such Purchase Orders.  Provided however, that subject to payment
             in advance to ASTC, DISTRIBUTOR shall be entitled to receive ASTC
             Products necessary to fulfill valid and binding Purchase Orders
             accepted by DISTRIBUTOR prior to notification of termination of
             this Agreement.  Prior to filling orders for such products ASTC
             shall be entitled to request and receive documentary evidence of
             all such outstanding Purchase Orders and an accounting of
             DISTRIBUTOR's then current inventory of ASTC Products.

     12.8.

             12.8.1.     Upon termination of this Agreement DISTRIBUTOR shall
                         refrain from use of any signs, equipment, advertising
                         matter, or material which refer to or are related to
                         ASTC and from acts and omissions that indicate or
                         suggest a relationship with ASTC.  DISTRIBUTOR shall
                         promptly return to ASTC all ASTC property, promotional
                         material and proprietary information.

             12.8.2.     Upon termination of the Agreement DISTRIBUTOR shall not
                         be entitled to any termination compensation,
                         consequential damages, indemnity, or other payment for
                         goodwill, lost profits, costs of re-establishment or
                         replacement of the business, or any other expenses, or
                         for loss of rights relating to the business established
                         by DISTRIBUTOR or rights relating to terminating to
                         this Agreement.

             12.8.3.     DISTRIBUTOR recognizes that prices charged by ASTC to
                         DISTRIBUTOR allow DISTRIBUTOR to obtain a reasonable
                         return for its entire services and profit on resale,
                         including costs of establishing and maintaining its
                         organization.  DISTRIBUTOR expressly acknowledges any
                         rights to such indemnity afforded to it by law or
                         custom, and to the extent permissible under applicable
                         law, expressly and completely waives all its rights to
                         such indemnity benefits, if any.

             12.8.4.     DISTRIBUTOR agrees to indemnify and hold ASTC harmless
                         from all losses, damages, amounts, costs, and expenses
                         incurred by ASTC as a result of claims or actions
                         brought by employees, agents, or representatives of
                         DISTRIBUTOR for any severance pay, compensations,
                         disability payment or social security payment or
                         compensation.

     12.9.   Upon any termination of this Agreement, ASTC shall buy back any
             unsold inventory that DISTRIBUTOR, will have at the time
             termination per the following schedule:

                    Products unused and less than  * * *  after shipment - * * *
                    of buying cost.

                    Products used and less than  * * *  after shipment - * * *
                    of buyer cost.

                    shipment - * * * of buying cost.

     12.10.  The aggregate amount to be paid to be paid to DISTRIBUTOR under the
             preceding subparagraph 12.9 may be offset by ASTC against any
             claims it has against DISTRIBUTOR, including claims for payment of
             goods supplied under this Agreement.

     12.11.  At the time of termination, ASTC shall take responsibility for all
             transactions relative to ASTC products including service of
             products.

13.  SUB-DISTRIBUTORS:  Nothing herein shall prohibit DISTRIBUTOR from
     appointing one or more sub-distributors within the Territory, provided
     however, that with respect to each such sub-distributor:

     13.1.   such appointment or appointments (including the sub-Territory to be
             assigned to any such sub-distributor) shall be consented to in

             sub-Territory;

     13.4.   such sub-distributor shall enter into and execute a sub-
             distribution agreement with DISTRIBUTOR (in form and content
             acceptable to ASTC) by the terms of which the sub-distributor
             agrees to be bound by all the terms of this Agreement; and

     13.5.   such sub-distributor shall agree in writing that nothing in this
             paragraph 13 shall be deemed to create the relationship of
             principal and agent, master and servant, partner, joint venturer,
             or any similar relationship between ASTC and any such sub-
             distributor.

     proprietary information.

3.   CAPABILITY TO PERFORM:  DISTRIBUTOR shall maintain the financial capability

     marketing, distribution, or advertising will not reflect unfavorably on, or

     ethical marketing.  DISTRIBUTOR agrees that it shall not do anything,
     directly, or impair the current image or to lower the prestige or quality
     of ASTC Products, or to impair the reputation of ASTC.

7.   DELIVERY, TITLE, RISK OF LOSS, AND RETURNS:

     7.1.    Firm Purchase Orders are to be placed by DISTRIBUTOR at least
             ninety (90) days prior to the required delivery date.  Forecasts of
             anticipated requirements of ASTC Products for each successive six-
             month period shall be supplied by DISTRIBUTOR semi-annually at
             least thirty (30) days prior to the end of each six (6) month
             period.  Products shall be shipped at DISTRIBUTOR's expense in such
             manner as ASTC shall deem appropriate or as otherwise directed.
             Title and risk of loss for ASTC Products shall remain with ASTC
             until delivery, FOB Chelmsford, Massachusetts, at which point title
             and risk of loss shall shift to DISTRIBUTOR.  DISTRIBUTOR shall
             obtain insurance sufficient to cover the value of each shipment or
             shall instruct ASTC to obtain such insurance and to bill

     7.2.    DISTRIBUTOR shall inspect all ASTC Products promptly upon receipt

             for such ASTC Product.  Any ASTC Product not properly rejected

             DISTRIBUTOR (the "Rejection Period") shall be deemed accepted.

     7.3.    To reject an ASTC Product, DISTRIBUTOR shall, within the Rejection
             Period, notify ASTC in writing of its rejection and in sufficient
             detail, the reasons for such rejection, and request a Return Goods
             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
             shall ship to ASTC the rejected products, freight prepaid, in its
             original shipping carton with the RGA number displayed on the
             outside of the carton.  ASTC reserves the right to refuse to accept
             any rejected products that do not bear an RGA number on the outside
             of the carton.  As promptly as possible but no later than forty
             five (45) working days after receipt of properly rejected products
             ASTC shall at its sole option and expense either repair or replace
             the rejected ASTC Products.  ASTC shall pay the shipping charges
             back to DISTRIBUTOR for properly rejected products; otherwise
             DISTRIBUTOR shall be responsible for the shipping charges.

     7.5.    Subsequent to the Rejection Period, DISTRIBUTOR may not return any
             ASTC Product to ASTC for any reason without ASTC's prior written
             consent.  For any ASTC product for which such consent has been
             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
             charges.

8.   WARRANTY:

     8.1.    DISTRIBUTOR shall pass on to its customers ASTC's standard Limited
             Warranty as set forth here, including the limitations set forth in

             shall, however, be entitled to mark the products with its trademark
             or trade name in a prominent place, subject to ASTC prior written
             consent.  DISTRIBUTOR is not authorized to use the trademark and

             manner except to indicate, during the term of this Agreement, that
             it is an independent authorized DISTRIBUTOR for ASTC and is selling
             ASTC products.  DISTRIBUTOR shall acquire no rights in the ASTC or
             3DSCOPE trademark and trade names, or any other trademark owned by

             this paragraph 10.

     10.5.   DISTRIBUTOR agrees to protect ASTC products against imitations and
             unfair competition by others, and will promptly provide ASTC
             written notice of any such conduct.  DISTRIBUTOR agrees to
             cooperate with ASTC at ASTC's request and expense, and to promptly
             take whatever action is required to cause the termination of such
             conduct.  ASTC reserves the right to take whatever action it deems
             appropriate to protect its trademarks and trade names.

             descriptive classification, arising out of the liabilities, duties
             and responsibilities above described which DISTRIBUTOR assumes or
             performs.  DISTRIBUTOR shall promptly notify ASTC of any and all

             proceedings arising out of the operation or performance of this
             Agreement.

     12.3.   ASTC warrants that all ASTC Products are in operating condition as
             of the time of shipment.  Nothing herein shall relieve ASTC of any
             obligation or liability existing under applicable law regarding
             claimed defects in the products supplied to DISTRIBUTOR by ASTC
             provided that

             12.3.1.     such defect existed as of the time the product was
                         shipped by ASTC;

             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

             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

             the transactions contemplated herein.

             Agreement, including these Standard Terms and Conditions, shall be

             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.

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

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

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

<PAGE>


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 90 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 sixty (60) days 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


                                         -16-

<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 sixty (60) days 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.

    6.5) MEDTRONIC'S TERMINATION FOR VISTA BREACH.

    (a)  Subject to Article 8 hereof, if Vista breaches any of its material

                                   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

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.

    8.2) NOTICE.  Upon giving notice to the other party, a party affected by an
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

suspension is commercially reasonable.

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,

this Agreement and the transactions contemplated herein, infringes, misuses,
misappropriates or conflicts with the rights, including patent and other
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
knowledge of Vista, no person or entity nor such person's or entity's business
or products has infringed, misused, misappropriated or conflicted with the Vista
Intellectual Property or currently is infringing, misusing, misappropriating or

     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


                                       -5-

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

* * * Confidential Treatment Requested

<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.

     7.1  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

<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.

Supply Term unless extended by the parties in accordance with the terms of this
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

non-breaching party. The breach may be cured after thirty (30) days of such 
notification by mutual written agreement of the parties.

which by their terms or nature are intended to survive such termination or

     9.10 CONSENTS.  Any consents or approvals given or required to be given
under this Agreement shall be effective only if given in writing and executed by
an executive officer of the party granting such consent or approval.

     9.11 WAIVER.  The failure of either party to enforce its rights under this
Agreement at any time for any period shall not be construed as a waiver of such
rights.

     9.12 ENTIRE AGREEMENT.  This Agreement together with any Appendices and
Addenda attached hereto and the Mutual Non-Disclosure Statement dated as of
October 16, 1995, between the parties, constitute the entire agreement between
the parties relating to the subject matter hereof, and supersede all prior or
contemporaneous written or oral negotiations, representations or agreements.  No
modification of this Agreement shall be binding on either party unless it is in
writing and signed by both parties.  In the event of any discrepancy or conflict
between the terms of this Agreement and any purchase order, invoice or other
report regarding the purchase and sale of Vista Systems hereunder, the terms of
this Agreement shall prevail.  Both parties acknowledge that this Agreement is
the result of mutual negotiation and therefore any ambiguity in its terms shall
not be construed against the drafting party.

     9.13 ARBITRATION.  All disputes, controversies or differences arising out
of or in relation to or in connection with this Agreement, which cannot be
settled by discussion and mutual accord shall be finally settled by binding
arbitration to be conducted in Los Angeles, California, in accordance with the
rules of the American Arbitration Association.  Demand for arbitration shall be
made in writing and shall be served upon the party or parties to whom the demand
is addressed in the manner provided for the tender of notices in Section 9.9
hereof.  Unless otherwise agreed by the parties, there shall be three (3)
arbitrators, one (1) chosen by each party and the third chosen by the two (2)
arbitrators.  The parties agree that all remedies, including equitable remedies,
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
entitled to award either party, punitive damages and that any consequential
damages claimed or awarded shall be reasonable.  In the event that consequential
damages are awarded in an arbitration hereunder, Vista may submit the
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
only as to consequential damages will be non-binding.  Furthermore, no such
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 
issuance of their award, to prepare a written finding of facts and law 
concerning the award.

     9.14 ATTORNEYS' FEES.  In the event of litigation or other legal proceeding
between the parties arising from this Agreement, the prevailing party shall be

recover, in addition to any other relief awarded or granted, its reasonable
costs and expenses (including attorneys' fees and expert witness costs) incurred
in the proceeding.

     9.15 COUNTERPARTS.  This Agreement may be executed in two counterparts,
each of which shall be deemed an original, but both of which together shall
constitute one and the same instrument.  If this Agreement is executed in
counterparts, no signatory hereto shall be bound until both the parties named
below have duly executed or caused to be duly executed a counterpart of this
Agreement.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
signed by their duly authorized representatives as of the Effective Date.

    2.1)  FIRST OFFER PURCHASE RIGHTS.

    (a)   Vista shall not enter into any transaction of the general types
described in subsection (b) below without first giving Vista's Notice (as
defined below) to Medtronic with respect thereto and complying with the terms of
this Section.

    (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
          otherwise acquire all or substantially all of the assets (excluding
          cash and marketable securities) of Vista, or to otherwise acquire
          control of Vista; or


                                         -4-

<PAGE>

          (ii)  Vista receives a bona fide offer from a Medtronic Competitor to
          purchase, in one or more transactions, capital stock (or securities
          exercisable for or convertible into capital stock) of Vista equal to
          20% or more of the issued and outstanding capital stock of Vista, or
          to purchase, license or otherwise acquire a Substantial Portion of
          Vista's Assets, or to otherwise acquire control of Vista; or

          (iii) Vista's Board of Directors determines that it wishes to sell,
          license, dispose of or otherwise transfer all or a Substantial
          Portion of Vista's Assets or 20% or more of the issued and
          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 five (5) days 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
Notice shall identify the third party offeror, in the case of (i) or (ii) above,
and shall set forth the material terms and provisions upon which Vista would be
willing to enter into a comparable transaction (the "Medtronic Transaction")
with Medtronic.

    (c)   During the Exclusive Period, Vista shall negotiate in good faith
exclusively with Medtronic regarding the Medtronic Transaction or any comparable
transaction.  During the Exclusive Period, Vista will not solicit offers from,
negotiate with, or provide information to any third party regarding the Proposed
Transaction or any comparable transaction.

    (d)   If Medtronic and Vista fail to reach mutual agreement upon the 
terms and provisions of definitive agreement(s) for the Medtronic Transaction 
during the Exclusive Period, then Vista shall have 90 days from the 
expiration of the Exclusive Period in which to enter into Definitive 
Agreements for the related Proposed Transaction with the third party whose 
bona fide offer was described in Vista's Notice (with respect to a Proposed 
Transaction described in (b)(i) or (b)(ii) above) or with any third party 
(with respect to a Proposed Transaction described in (b)(iii) above); 
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 final terms and provisions proposed by Medtronic during the 
Exclusive Period.  If Vista fails to enter into such Definitive Agreements 
with respect to such particular Proposed Transaction within such 90 day 
period or if such Proposed Transaction is not completed within 120 days 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.


                                         -5-

<PAGE>

    (e)   Medtronic's "First Offer Purchase Rights" pursuant to this Section 
2.1 shall terminate upon the earlier of (i) the four-year 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 net proceeds to Vista of more than $15 million, or (iii) if Vista has 
complied 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 10% 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 $15 million 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

in no way be construed to be a waiver of any such provision, nor in any way to
affect the validity of this Agreement or any part thereof or the right of the
party thereafter to enforce each and every such provision.  No waiver of any
breach of this Agreement shall be held to be a waiver of any other or subsequent

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


                            ARTICLE 1 -- DEFINITIONS

     For the purposes of this Agreement, the following words and phrases shall
have the following meanings:

     1.1  "Licensee" shall mean American Surgical Technologies Corporation and
any subsidiary of American Surgical Technologies Corporation.


     1.2  "Subsidiary" shall mean any corporation, division, company or other
entity more than fifty percent (50%) of whose voting stock is owned or
controlled directly or indirectly by American Surgical Technologies Corporation.

     1.3  "Technology" shall mean certain existing Patent Rights (as defined
below), Licensed Processes (as defined below), Know How, copyrights, trade
secrets, inventions and other intellectual property or proprietary rights, as
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
whole or in part by a valid and unexpired claim contained in a Patent Rights
Patent, or (c) otherwise materially incorporates any of the Technology.

     1.7  "Marketing Period" shall mean any twelve (12) month period commencing
on the second or any subsequent anniversary of the date of initial marketing
release by Licensee of a Licensed Product.

the Licensed Product(s), then, for purposes of determining Net Sales as set
forth above, the deemed invoiced price for the Licensed Product(s) in the system
shall be determined by multiplying (i) the total invoiced price for the system
by (ii) a fraction, the numerator of which is the Licensee's then-current list
price for the Licensed Product which is part of the system (or which is the
total of the Licensee's then-current list prices for all Licensed Product(s)
sold as part of the system, if the system includes more than one Licensed
Product) and the denominator of which is the total of the Licensee's then-

                         ARTICLE 6 -- PATENT PROSECUTION

     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
obligation hereunder to reimburse Licensor for expenses incurred by Licensor to
date in connection with foreign Patent Rights Patents or Patent Rights
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
confirm in Licensee's, its successor's, assigns, and nominees, all rights
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
may be necessary to permit Licensee to obtain any patents or copyrights or any
assignments thereof.


                            ARTICLE 7 -- TERMINATION

     7.1  Should Licensee fail in its remittance to Licensor of license
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 30 days after
such notice unless Licensee shall pay to Licensor, within the 30 day period, all
such royalties due and payable.  Upon the expiration of the 30 day period, if
Licensee shall not have paid all such monies due and payable, the exclusive
rights, privileges and license granted hereunder shall thereupon immediately
terminate as provided in Section 2.2, and the license granted hereunder shall
thereupon be nonexclusive as provided in said Section 2.4.

     7.2  Except as is provided in Section 7.1 above with respect to failure to
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 45 days after mailing of such notice
unless Licensee shall have cured any breach underlying such notice within the
45 day period.  Upon the expiration of the 45 day 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.


<PAGE>

     7.3  Licensee shall have the right to terminate this Agreement at any time
upon 60 days 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 month in which such termination takes effect
and for the five months following such month.  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
prior to the effective date of such termination, which obligation(s) shall
continue until fully met by such party.

     7.6  Notwithstanding the foregoing, following termination hereunder, the
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
arise concerning the validity, construction or effect of any patent licensed
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



<PAGE>

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.


                            ARTICLE 9 -- INFRINGEMENT

any alleged infringement of which it shall have notice committed by a third
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.

                                  LICENSE AGREEMENT



      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
development and marketing of Visual Instruments employing advanced optical
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

related to developments and improvements of the Licensed Products and Licensor's
Technology made by Licensee during the term of this Agreement.

ARTICLE 2 -- GRANT

Newman hereby grants to Vista an exclusive license to use Licensor's Technology
to develop, make, use, have made, market, Lease, and sell the Licensed Products
and derivatives of them worldwide.  Newman further grants to Vista the right to

third parties subject to Newman's prior approval of any such sublicense as
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 percentage of net sales of the
      Licensed Products.  Royalty rates (R) will be based on the cumulative 
      overall gross margin (G) of the Licensed Products as follows:

      a.     For the disposable or semi-disposable components line of products 
             (endoscopes, disposable packs, etc.): R = 0.2(G-45) where R and G 
             are in percent (%).  If G drops below 45%, no royalty will be paid.

      b.     For the devices line of products (eye pieces, special cameras, 
             light sources, etc.): R = 1% if G > 50%; or R = 0% if G < 50%.

When total royalties due for all Licensed Products reach $400,000 in any
calendar year, then the royalty rate for the Licensed Products identified in
5.1(a) will change to R = 0.15 (G-45) for subsequent sales until the end of
that year.

The above gross margin percentages 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 
twenty five (25) percentage points (for example, 45% will be reduced to 20%; 
50%, to 25%; etc.).

                                          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 $37,500 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 $37,500 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 seven (7) 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


                                          6


<PAGE>

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 ninety (90) days
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 ninety (90) days 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 ninety 
(90) days 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


                                          7

Newman and, depending on the circumstances, may seek to recover royalties
previously paid.

                                  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.


                                         -1-


<PAGE>

      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 Two Hundred Thousand Dollars ($200,000).

      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 fifty percent (50%) 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

                                      ARTICLE 2
                                   GRANT OF RIGHTS

      2.1    LICENSE.  In consideration of the license fees and royalties

<PAGE>

Vista to the third party under confidentiality restrictions at least as severe

      2.4    IMPROVEMENTS.

             (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.

                          OWNERSHIP AND FURTHER DEVELOPMENT

      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

      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 thirty (30) days after written notice is given by the 
nonbreaching party to the breaching party specifying the breach.  The parties 
agree that if: (i) two (2) consecutive royalty payments are not paid when due 
under Section 4.4, and Urohealth fails to pay such royalties within the 
thirty (30) days after written notification from Vista, (ii) Urohealth fails 
to pay all prosecution, maintenance and infringement costs associated with 
the Patent Rights within thirty (30) days after written notification from 
Vista, (iii) Urohealth fails to comply with the additional qualifications set 
forth in Article 9 of this Agreement within thirty (30) 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 thirty (30) 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.

             (a)    Termination of this Agreement for any reason shall not
release either party hereto from any liability which at the time of such
termination has already accrued to the other party.

             (b)    In the event this Agreement is terminated for any reason,
Urohealth shall have the right to sell or otherwise dispose of its existing
stock of Licensed Products as completed products.

             (c)    Articles 7, 8, and 10 shall survive the expiration or
termination of this Agreement for any reason.


                                      ARTICLE 6
                               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.

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:

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

within thirty (30) days following written notice of the breach from the
non-breaching party.  In addition, this Agreement shall be terminated
automatically upon the (i) termination of the License Agreement or (ii) death or
incapacity, whether mental or physical, of Newman.  UROHEALTH or its designee
shall determine in good faith whether Newman is incapacitated for the purposes
of this Section 3. In addition, UROHEALTH may in its sole discretion terminate

Notwithstanding anything to the contrary herein contained, in the event
performance by either party hereto of any term, covenant, condition or provision
of this Agreement shall (i) jeopardize the licensure of UROHEALTH, (ii)
jeopardize its participation in (a) Medicare, Medicaid, Blue Cross, or other
reimbursement or payment programs, or (b) the FDA approval process, regulatory
program and guidelines, or (c) any other state or nationally recognized
accrediting organization, or (iii) be in violation of any statute, ordinance, or
be otherwise deemed illegal, or be deemed unethical by any recognized body,

Information").  Confidential Information shall include, but not be limited to,
that information which is designated as confidential either in writing or
orally, or that information which is not generally known to the public.  With

Information in confidence; and (c) use the Confidential Information only for the
purpose of performing its obligations under this Agreement.  Notwithstanding
anything to the contrary herein, Consultant shall not have an obligation to
preserve the confidentiality of any Confidential Information which was
previously known to Consultant free of any obligation to keep it confidential or

provisions of this Section 6 shall survive expiration or termination of this
Agreement for any reason.  As used herein, "Confidential Information" shall not

License Agreement.

      SECTION 7.  STATUS OF THE PARTIES.  In the performance of this Agreement,
it is mutually understood and agreed that Consultant, Newman, its other

contractors with, and not as an employee, partner, or joint venturer of or with
UROHEALTH.  Neither Consultant nor Newman shall have any claim under this
Agreement or otherwise against UROHEALTH for workers' compensation, unemployment
compensation, vacation pay, sick leave, disability benefits, retirement
benefits, social security benefits or any other employee benefits of any kind,
all of which shall be the sole responsibility of Consultant.  UROHEALTH shall
not withhold on behalf of Consultant or Newman pursuant to this Agreement any
sums for income tax, unemployment insurance, social security or otherwise
pursuant to any law or requirement of any government agency, and all such
withholding, if any is required, shall also be the sole responsibility of
Consultant.  Consultant shall indemnify and hold UROHEALTH harmless from any and
all loss or liability, if any, arising with respect to any of the foregoing
benefits or withholding requirements.

      SECTION 8.  GOVERNING LAW.  This Agreement is being delivered and
executed in the State of California and the validity, construction, and

the State of California.  Venue shall be proper only in a court of competent
jurisdiction located in the State of California.  The parties agree to be
subject to personal jurisdiction and consent to service of process issued by a
court in which venue is proper as defined in this Section 8.

shall be deemed effective unless in writing and signed by each of the parties to
which it applies.  Any waiver of a breach of any provision of this Agreement
shall not be deemed effective unless in writing and signed by the party against
whom enforcement of the waiver is sought.

      SECTION 10.  HEADINGS.  The descriptive headings of this Agreement are
inserted for convenience only and shall not control or affect the meaning or
construction of any provision hereof.

      SECTION 11.  ASSIGNMENT.  Neither party may assign, delegate,
subcontract, or otherwise transfer its rights or obligations hereunder without
the prior written consent of the other party and any assignment or other
transfer in violation of this Section 11 shall be void; provided, however, that
UROHEALTH may assign its rights and delegate its duties pursuant to this
Agreement to any successor, subsidiary, or affiliate to the business of

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

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 ninety (90) days 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.

[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.

                          BRIEF DESCRIPTION OF THE DRAWINGS

    FIG. 1 illustrates an embodiment of an optical collimation system according
to the present invention, in a heads-up display/image combiner application;
    FIG. 2(a) illustrates the transmission characteristics of a cholesteric
liquid crystal element reflective to RHCP green light;
    FIG. 2(b) is a graphical representation of transmission and polarization
efficiency of a cholesteric liquid crystal element;
    FIG. 3 illustrates an alternate embodiment of an optical collimation system
according to the present invention;
    FIG. 4 is a graph illustrating the angular dependence of the wavelength of
maximum reflection; and
    FIGS. 5(a) and 5(b) illustrate the biasing of the reflection angle from the
cholesteric liquid crystal element through the use of surface tilt, untilted and
tilted cases respectively.

                             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.
    What is claimed is:
    1. An optical collimating apparatus for focussing an image at or closer
than at an infinite distance from an observer, comprising the elements of:
    a circular polarizing filter;
    a semi-reflective concave mirror; and
    a cholesteric liquid crystal element.
    2. An optical collimating apparatus for focussing an image at or closer
than at an infinite distance from an observer, wherein the image is
substantially transmitted by a semi-reflective concave mirror and a first
portion of said transmitted image is further transmitted unreflected to the
observer by a cholesteric liquid crystal element and a second portion of said
transmitted image is reflected by the cholesteric liquid crystal element to the
concave mirror, which reflects the second portion of the transmitted image back
to the cholesteric liquid crystal element, which transmits the second portion of
the transmitted image to the observer, comprising the elements of:
    an image source;
    a circular polarizing filter;
    a semi-reflective concave mirror; and
    a cholesteric liquid crystal element.

    * * *       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.

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 thirty (30) days after written notice is given by the 
nonbreaching party to the breaching party specifying the breach.  The parties

under Section 4.4, and Urohealth fails to pay such royalties within the

the Patent Rights within thirty (30) days after written notification from

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

benefit of creditors, or (iii) upon the other party's dissolution or ceasing to
do business.

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

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 thirty (30) days after receipt by Urohealth of written notice thereof
from Vista, Vista shall have the right to terminate this Agreement with the same

hereof.

                               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.

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.

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

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

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.

ARTICLE 5 - LICENSE FEES AND ROYALTIES

5.1 LICENSE FEE.  In consideration of the rights granted by GDE to Vista
pursuant to this Agreement, Vista shall pay a non-refundable license fee of Five
Hundred Thousand Dollars ($500,000.00) payable as follows:

    (i)  $250,000.00 in Vista stock at the price set at an IPO; this amount
         shall not be considered an advance against future royalties; and

    (ii) $250,000.00 by December 31, 1998, as a combination of royalty payments
         made through such date and a royalty advance creditable against future
         royalties due thereafter.

5.1.1    STOCK.  Vista will provide the stock to GDE within ten (10) business
days of the close of Vista's IPO.  If the IPO does not occur prior to June 30,

    "Sales Revenue" shall mean the net sales revenue received by Vista from
third party customers, excluding freight and similar charges.  If the software
product incorporating GDE Intellectual Property is a module which is not
separately billed to the third party customer, then GDE's.royalty will be based
upon a proportion of the total price billed.  Such proportion will be determined
based upon the overall price of the system and the sales value of the module if
it was separately billed, such determination to be made by GDE and Vista in good
faith and verifiable by GDE by means of normal audit rights.

5.3 ROYALTY PAYMENT.  During the license exclusivity period, Vista will pay 
to GDE an amount equal to *** on Sales Revenues of software products based 
upon, or derived from, any Licensed Product, or part thereof.

and accounts as are reasonably necessary to verify the payments due GDE under
this Agreement.  At GDE's sole expense, an independent certified public
accountant, selected by GDE and reasonably acceptable to Vista, who agrees to
sign a nondisclosure agreement may, upon reasonable notice and during normal
business hours, but no more than once each calendar year, inspect only those
records of Vista on which the payments to GDE under this Agreement are based.
The accountant may report only the accuracy of the payments, but may not
disclose confidential information, such as specific customers.  If any audit
hereunder reveals that Vista has failed properly to account for and pay
royalties owing to GDE hereunder, and the amount of any royalties which Vista
has failed properly to account for and pay during any twelve (12) month period
exceeds by ten percent (10%) or more the royalties actually accounted for and
paid to GDE for such period, Vista shall reimburse GDE for the cost of the
accountant.  Vista shall also, within thirty (30) days after notification by
GDE, pay to GDE any amounts shown as due under such audit, regardless of whether
Vista is required to reimburse GDE for the cost of the accountant.

GDE agrees to release three (3) employees to join Vista, including Robert D.
Bowen, President of HealthCom, and two (2) engineers to be mutually determined.

possible.  Vista agrees not to solicit or recruit for hire other GDE or
HealthCom employees.

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

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

to make royalty payments to GDE for such Licensed Items that are the subject of

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.

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 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


                                         -14-

<PAGE>

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.

                      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

administrative jurisdiction under the Plan, have full authority to determine,

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 300,000 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.

                       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

Stock Issuance


                                      -13-

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

(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).

terminated rights shall immediately vest, in the event the Participant's Service

  III.    SHARE ESCROW/LEGENDS

          Unvested shares may, in the Plan Administrator's discretion, be held

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.
