                                  THE COMPANY
 
Nitinol Medical Technologies, Inc. designs, develops, and markets innovative
medical devices that utilize advanced materials and are delivered by minimally
invasive procedures. The Company's products are designed to offer alternative
approaches to existing complex treatments, thereby reducing patient trauma,
shortening procedure, hospitalization and recovery times, and lowering overall
treatment costs. The Company's patented medical devices include self-expanding
stents, vena cava filters and septal repair devices. At this time, the
Company's stents are in European clinical trials for certain indications, its
vena cava filters are marketed in the United States and abroad, and the Company
is completing the development of its septal repair device.
 
NMT has developed an expertise in precisely engineering nitinol and other
advanced materials for a variety of innovative medical device applications.
Nitinol is a nickel-titanium alloy that exhibits unique superelastic and
thermal shape-memory characteristics which enable the Company's nitinol-based
medical devices to transform into their intended shape once deployed into the
body. The Company has developed capabilities in advanced device fabrication,
materials characterization, manufacturing and process control and sophisticated
in vitro testing resulting in highly efficient and reliable manufacturing
processes.
   
The Company has established arrangements with Boston Scientific Corporation
("Boston Scientific") and C. R. Bard, Inc. ("Bard"), worldwide leaders in sales
of minimally invasive medical devices, for the distribution, sale and marketing
of its stents and its nitinol vena cava filter, respectively.     
 
                               BUSINESS STRATEGY
 
The Company's strategy is to develop and commercialize a broad range of
advanced medical devices for minimally invasive applications to address unmet
medical needs by (i) designing and developing new products by leveraging its
core technologies to precisely engineer nitinol and other advanced materials,
(ii) continuing to market products with more extensive distribution
requirements through collaborations with established market leaders, (iii)
creating direct marketing and distribution capabilities for products, such as
the septal repair device, with smaller and more easily accessible user groups,
(iv) developing commercial scale manufacturing facilities to become a fully-
integrated medical device company, and (v) seeking licensing and acquisition
opportunities that will complement the Company's business and strengthen its
competitive position.
 
                                    PRODUCTS
   
Stents. NMT's patented self-expanding nitinol stents are designed to hold open
arteries, veins and other passageways of the body that have closed or become
obstructed as a result of aging, disease or trauma. The Company's stents are
placed in the body using catheter-based delivery systems. Once deployed, they
exert radial force against the walls of passageways to enable such passageways
to remain open and functional. NMT's proprietary stents can be manufactured in
a variety of sizes, shapes and flexibilities and with varying radial force
characteristics to treat a number of specific medical indications. Stents have
emerged as one of the fastest growing segments of the medical device market and
are increasingly being used as adjuncts or alternatives to a variety of medical
procedures. From its infancy in 1990, the stent market has grown to estimated
worldwide sales of $500 million in 1995, with continued growth expected. In
November 1994, the Company entered into an exclusive license agreement with
Boston Scientific to further develop, manufacture, market and distribute     
 
                                       3
<PAGE>
 
NMT's stents worldwide. Boston Scientific is currently conducting clinical
trials in Europe for peripheral vascular stenting and peripheral vascular stent
grafting applications. The Company has been advised by Boston Scientific that
it intends to commence marketing of the Company's peripheral vascular stents in
Europe during 1996 and that it intends to seek Food and Drug Administration
("FDA") approval for an Investigational Device Exemption ("IDE") to permit the
commencement of United States clinical trials for peripheral vascular stenting
in the near future.
 
Vena Cava Filters. The Company's patented Simon Nitinol Filter ("SNF") is a
nitinol vena cava filter designed to prevent pulmonary embolism (a blood clot
lodged in the vessels supplying blood to the lungs), a condition which results
in approximately 125,000 to 150,000 deaths annually in the United States. Vena
cava filters are generally used in cases where drug therapy has failed or is
contraindicated. The Company's vena cava filter is implanted using the
Company's patented, catheter-based delivery systems from veins in the leg or
neck. Additionally, the SNF is the only currently available vena cava filter
which can be implanted from veins in the arm. In 1990, the Company obtained FDA
clearance to market the SNF in the United States. The SNF has been distributed
in the United States and certain other countries by the Bard Radiology Division
of Bard ("Bard Radiology") since 1992. In 1996, Bard International, Inc. ("Bard
International") began distributing the SNF outside the United States.
 
Septal Repair Devices. The Company is currently completing the development of
the CardioSeal Septal Occluder, an innovative, patented device for the
minimally invasive repair of defects in the septal wall of the heart, commonly
known as "holes in the heart." These defects, which occur primarily in
children, presently are treated by open heart surgery. The Company believes
that the CardioSeal Septal Occluder may be suitable for use in approximately
55,000 patient implants annually for congenital heart defects, as well as for
approximately 145,000 adult patients annually with Patent Foramen Ovale,
another septal defect which may contribute to embolic stroke. The septal repair
device was originally developed by Bard in collaboration with Children's
Hospital of Boston. NMT acquired the rights to develop and commercialize the
septal repair device in February 1996. The Company believes that the clinical
utility of the septal repair device was demonstrated with an earlier version of
the device that was evaluated in over 700 patients in clinical trials conducted
between 1989 and 1991. Children's Hospital of Boston is conducting clinical
trials of the current version of the septal repair device under an IDE
permitting implantation of such devices in patients at high risk for surgery.
In August 1996, the Company received conditional approval of its IDE
application from the FDA to conduct multi-center clinical trials of the
CardioSeal Septal Occluder in the United States. NMT intends to begin clinical
trials for the CardioSeal Septal Occluder in the United States, Canada and
Europe in late 1996.
 
The Company's principal executive offices are located at 263 Summer Street,
Boston, MA 02210, and its telephone number is (617) 737-0930.

                                  RISK FACTORS
 
In addition to the other information in this Prospectus, the following factors
should be considered carefully by prospective investors in evaluating the
Company and its business before purchasing shares of Common Stock offered
hereby.
 
LIMITED COMMERCIALIZATION; UNCERTAINTIES OF PRODUCT DEVELOPMENT AND MARKET
ACCEPTANCE
 
The Company currently markets only one product, the Simon Nitinol Filter. The
Company's stents and CardioSeal Septal Occluder may require substantial further
investment in research, product development, preclinical and clinical testing
and governmental regulatory approvals prior to being marketed and sold in the
United States and other countries. The Company's success will depend, in part,
on its ability, either by itself or in collaboration with others, to complete
such product development efforts, obtain such regulatory approvals, establish
manufacturing and marketing programs for such proposed products and gain market
acceptance.
 
The Company's product development efforts are subject to the risks inherent in
the development of products based on innovative technologies. These risks
include the possibilities that the Company's technologies or any or all of its
products will be found to be ineffective or unsafe, or will otherwise fail to
receive necessary regulatory approvals; that the products, if safe and
effective, will be difficult to manufacture on a large scale or be uneconomical
to market; that the proprietary rights of third parties will interfere with the
Company's product development; or that third parties will market superior or
equivalent products which achieve greater market acceptance. Furthermore, there
can be no assurance that the Company or its collaborators will conduct their
product development efforts within the time frames currently anticipated or
that such efforts will be completed successfully. See "Business--Products."
 
There can be no assurance that the Company's stents, septal repair devices, or
any other products developed by the Company will achieve market acceptance. The
degree of market acceptance for the Company's products will depend upon a
number of factors, including the receipt and timing of regulatory approvals,
the establishment and demonstration in the medical community of the clinical
safety, efficacy and cost-effectiveness of the Company's products and their
advantages over existing technologies. Additionally, certain of the medical
indications that can be treated by the Company's devices can also be treated by
surgery, drugs or other medical devices. Many alternative treatments currently
are widely accepted in the medical community and have a long history of use.
There can be no assurance that the Company's devices and procedures will be
able to replace such established treatments or that physicians or the medical
community in general will accept and utilize the Company's devices or any other
medical products that may be developed by the Company. Long-term market
acceptance of NMT's products will depend, in part, on the capabilities and
operating features of the Company's products as compared to other available
products. Failure of the Company's products to gain market acceptance would
have a material adverse effect on the Company's business, financial condition
and results of operations. See "--Intense Competition; Rapid Technological
Change" and "Business--Products."
 
DEPENDENCE UPON COLLABORATORS
 
The Company has entered into distribution agreements with Bard Radiology and
Bard International granting them exclusive distribution rights to the Company's
SNF, and a license agreement with Boston Scientific granting Boston Scientific
exclusive worldwide rights to develop, manufacture, market and distribute the
Company's stent technology and products which incorporate such technology.
Although Bard Radiology and Bard International have agreed not to sell
competing filters, Boston Scientific is not prohibited from selling other
stents and, in fact, manufactures and licenses from others a variety of stents
that may compete with the Company's stents. Boston Scientific may choose to
emphasize such other stents in its developmental and marketing efforts. See "--
Intense Competition; Rapid Technological Change."
 
The Company's future product development and marketing depends on the success
of these arrangements and the ability to renew such arrangements. There can be
no assurance that such arrangements will be renewed or that the Company's
existing relationships with Bard Radiology, Bard International or Boston
Scientific will continue in their current form. The Company's business could be
materially adversely affected if its arrangements with Bard Radiology, Bard
International or Boston Scientific prove unsuccessful or if such companies
terminate their arrangements with the Company, negotiate lower prices, sell
additional competing products, whether manufactured by themselves or others, or
otherwise alter the nature of their relationships with the Company. The amount
and timing of resources to be devoted by the Company's existing and future
collaborators to performing their contractual responsibilities are not
 
                                       6
<PAGE>
 
within the control of the Company. In addition, there can be no assurance that
such collaborators will perform their obligations as expected or that the
Company will derive any additional revenue from such arrangements. There also
can be no assurance that the Company's collaborators will not pursue existing
or alternative technologies in preference to products being developed in
collaboration with the Company. There can be no assurance that the Company will
be able to negotiate additional collaborative arrangements in the future on
acceptable terms, if at all, or that such collaborative arrangements will be
successful. See "Business--Strategy," "Business--Products" and "Business--
Agreements with Boston Scientific and Bard."
 
INTENSE COMPETITION; RAPID TECHNOLOGICAL CHANGE
 
The medical device industry is characterized by rapidly evolving technology and
intense competition. Other companies in the medical device industry are
currently marketing products that compete with the Company's devices and may be
developing, or could in the future develop, additional products that are
competitive with the Company's. Many of the Company's competitors have
substantially greater capital resources, greater research and development,
manufacturing and marketing resources and experience and greater name
recognition than the Company. There can be no assurance that the Company will
be able to compete against such competitors and potential competitors in terms
of research and development, manufacturing, marketing and sales. Certain of the
Company's competitors, including Johnson & Johnson, Inc., currently market
stents, and Boston Scientific, which has entered into an exclusive license
agreement with the Company relating to the Company's stent technology,
distributes competing stents, competes with the Company in the vena cava filter
market and has substantially greater sales than the Company. The Company
believes that other companies are actively developing competitive septal repair
devices. Such companies may succeed in obtaining regulatory approvals and
commercializing their septal repair devices sooner than the Company. There can
be no assurance that the Company's competitors will not succeed in developing
or marketing technologies and products that are more effective than those
developed or marketed by the Company or that would render the Company's
technology and products obsolete or noncompetitive. Additionally, new surgical
procedures and medications could be developed that replace or reduce the
importance of current or future procedures that use the Company's products.
Accordingly, the Company's success will depend in part on its ability to
respond quickly to medical and technological changes through the development
and introduction of new products. Product development involves a high degree of
risk and there can be no assurance that the Company's new product development
efforts will result in any commercially successful products. Additionally, in
many cases the medical indications that can be treated by the Company's devices
can also be treated by surgery and drugs as well as other medical devices. See
"Business--Products."
 
EXPECTED NEAR-TERM LOSSES
 
The Company expects operating losses to continue at least through early 1997 as
it continues to expend substantial resources to complete development of the
Company's products, seek regulatory clearances or approvals, build its
marketing, sales and manufacturing organizations and conduct further research
and development. There can be no assurance that the Company's products under
development will ever gain commercial acceptance, generate revenues or achieve
profitability or that the Company will resume profitability. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
LIMITED MANUFACTURING HISTORY; DEPENDENCE ON THIRD PARTY MANUFACTURERS
 
The Company currently uses third parties to manufacture and distribute the SNF
and, pursuant to its exclusive license agreement, will use Boston Scientific to
manufacture and distribute its stents. The Company intends to continue to use
third parties to manufacture and distribute such products and certain other
products which the Company may seek to develop.
 
If the Company should encounter delays or difficulties with third party
manufacturers in producing, packaging or distributing its proposed products,
market introduction and subsequent sales of such products would be adversely
affected and the Company may have to seek alternative sources of supply. No
assurance can be made that the Company will be able to enter into alternative
supply arrangements at commercially acceptable rates, if at all. Moreover,
contract manufacturers that the Company may use must adhere to current Good
Manufacturing Practice ("GMP") regulations enforced by the FDA. If the Company
is unable to obtain or retain third party manufacturers on commercially
acceptable terms, it may not be able to commercialize medical products as
planned. The Company's dependence upon third parties for the manufacture of
medical products may materially adversely affect the Company's profit margins
and its ability to develop and distribute products on a timely and competitive
basis.
 
                                       7
<PAGE>
 
The Company plans to manufacture the CardioSeal Septal Occluder itself and, for
such purpose, is currently constructing its own manufacturing facility. The
Company has had no previous experience in the scale-up or manufacture of
medical products. The Company's manufacturing facility will be subject to GMP,
ISO 9000 and other regulatory requirements, will be subject to risks regarding
delays or difficulties encountered in manufacturing any such medical products
and will require a substantial investment of capital. There can be no assurance
that the Company will be able to manufacture any such products successfully or
in a cost-effective manner or that the Company can achieve and maintain
compliance with GMP, ISO 9000 and other regulatory requirements. See
"Business--Products" and "Business--Government Regulation."
 
LIMITED MARKETING AND SALES EXPERIENCE
 
Although the Company has limited internal marketing and sales resources and
personnel, and currently relies primarily on third parties to market and sell
its products, the Company plans to market the CardioSeal Septal Occluder
directly, if and when it receives the required regulatory approvals. In order
to market the CardioSeal Septal Occluder and any other products that it may
develop, the Company will have to develop a marketing and sales organization
with technical expertise and distribution capabilities. The development of such
an organization will require significant expenditures, management resources and
time. There can be no assurance that the Company will be able to develop such a
marketing and sales organization. See "Business--Products."
 
DEPENDENCE ON PATENTS AND PROPRIETARY TECHNOLOGY
 
The Company's success will depend, in part, on its ability to obtain patents,
maintain trade secret protection and operate without infringing on the
proprietary rights of third parties. The validity and breadth of claims covered
in medical technology patents involve complex legal and factual questions and,
therefore, may be highly uncertain. No assurance can be given that any pending
patent applications or any future patent application will result in issued
patents, the scope of any patent protection will exclude competitors or provide
competitive advantages to the Company, any of the Company's patents will be
held valid if subsequently challenged or others will not claim rights in or
ownership of the patents and other proprietary rights held by the Company.
Furthermore, there can be no assurances that others have not or will not
develop similar products, duplicate any of the Company's products or design
around any patents issued or that may be issued in the future to the Company or
its licensors. In addition, whether or not patents are issued to the Company or
its licensors, others may hold or receive patents which contain claims having a
scope that covers products developed by the Company.
 
Moreover, there can be no assurances that patents issued to or licensed by or
to the Company will not be challenged, invalidated or circumvented or that the
rights thereunder will provide any competitive advantage. The Company could
incur substantial costs in defending any patent infringement suits or in
asserting any patent rights, including those granted by third parties. In
addition, the Company may be required to obtain licenses to patents or
proprietary rights from third parties. There can be no assurance that such
licenses will be available on acceptable terms if at all. If the Company does
not obtain required licenses, it could encounter delays in product development
or find that the development, manufacture or sale of products requiring such
licenses could be foreclosed. See "Business--Patents and Proprietary Rights"
and "Business--Licensed Technology; Royalty Obligations."
 
The Company also relies on unpatented proprietary technology, trade secrets and
know-how and no assurance can be given that others will not independently
develop substantially equivalent proprietary information, techniques or
processes, that such technology or know-how will not be disclosed or that the
Company can meaningfully protect its rights to such unpatented proprietary
technology, trade secrets, or know-how. Although the Company has entered into
non-disclosure agreements with its employees and consultants, there can be no
assurance that such non-disclosure agreements will provide adequate protection
for the Company's trade secrets or other proprietary know-how.
 
GOVERNMENT REGULATION; PRODUCT APPROVALS UNCERTAIN
 
The manufacture and sale of medical devices intended for commercial
distribution are subject to extensive governmental regulations in the United
States. Medical devices are regulated in the United States by the FDA under the
Federal Food, Drug, and Cosmetic Act (the "FDC Act") and generally require pre-
market clearance or pre-market approval prior to commercial distribution. In
addition, certain material changes or modifications to medical devices also are
subject to FDA review and clearance or approval. Pursuant to the FDC Act, the
FDA regulates the research, testing, manufacture, safety, labeling, storage,
record keeping, advertising, distribution and production of medical devices in
the United States. Noncompliance with applicable requirements can result in
failure of the government to
 
                                       8
<PAGE>
 
grant pre-market clearance or approval for devices, withdrawal of approvals,
total or partial suspension of production, fines, injunctions, civil penalties,
recall or seizure of products, and criminal prosecution. The FDA also has the
authority to request repair, replacement or refund of the cost of any device
manufactured or distributed by the Company.
 
Generally, before a new device can be introduced into the market in the United
States, the manufacturer must obtain FDA clearance of a pre-market notification
("510(k) notification") or approval of a PMA application. If a medical device
manufacturer can establish that a device is "substantially equivalent" to a
legally marketed device, the manufacturer may seek clearance from the FDA to
market the device by filing a 510(k) notification. If a manufacturer or
distributor of medical devices cannot establish that a proposed device is
substantially equivalent to a legally marketed device, the manufacturer must
seek pre-market approval of the proposed device through submission of a PMA
application.
 
The PMA approval process is expensive, uncertain and lengthy. A number of
devices for which pre-market approval has been sought by other companies have
never been approved for marketing. The review time is often significantly
extended by the FDA, which may require more information or clarification of
information already provided in the submission. In addition, the FDA will
inspect the manufacturing facility to ensure compliance with the GMP
regulations for medical devices prior to approval of the PMA application. If
granted, the approval may include significant limitations on the indicated uses
for which a product may be marketed.
 
Any products manufactured or distributed by the Company are subject to
continuing regulation by the FDA including record keeping requirements,
reporting of adverse experience with the use of the device, postmarket
surveillance, postmarket registry and other actions deemed necessary by the
FDA. The FDA's regulations require agency approval of a PMA supplement for
certain changes if they affect the safety and effectiveness of the device,
including, but not limited to, new indications for use; labeling changes; the
use of a different facility to manufacture, process, or package the device. For
any devices that are cleared through the 510(k) process, modifications or
enhancements that could significantly affect safety or effectiveness, or that
constitute a major change in the intended use of the device, will require new
510(k) submissions. There can be no assurance that the Company will be able to
obtain necessary regulatory approvals or clearances for its products on a
timely basis or at all, and delays in receipt of, or failure to receive, such
approvals or clearances, the loss of previously received approvals or
clearances, limitations on intended use imposed as a condition of such
approvals or clearances, or failure to comply with existing or future
regulatory requirements could have a material adverse effect on the Company's
business, financial conditions and results of operations.
 
The Company's first product, the SNF, underwent significant clinical
investigation under an IDE and received 510(k) clearance in 1990. Subsequent
improvements and modifications to the SNF have also received 510(k) clearance
from the FDA. There can be no assurance that future modifications of the device
will obtain such clearance. The 510(k) clearances for the SNF were based on
substantial equivalence of the device to other cardiovascular intravascular
filters, which are "preamendments Class III devices." It is likely that the FDA
will call for PMAs for such preamendments Class III devices, including the SNF,
and that the Company will be required to have a PMA for the SNF accepted for
filing by the FDA within 90 days after the date that the FDA calls for PMAs.
There can be no assurance that the Company will be able to file a PMA within
the prescribed time period or that any data and information submitted in a PMA
will be adequate to support approval of the device. If the FDA were to require
the Company to conduct a new clinical study to support the safety and efficacy
of the SNF, the preparation of the PMA would take substantially longer than 90
days. Failure of the Company to submit a PMA and have it accepted for filing by
the FDA within the required time frame could result in the Company being
required to cease commercial distribution of the SNF. In addition the Company
may not be permitted to continue commercial distribution of the SNF pending the
FDA's review of the PMA. The Company's failure to have a PMA accepted for
filing, or a failure to obtain FDA approval of the PMA, would result in the
Company being required to cease commercial distribution of the SNF which would
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
Sales of medical device products outside the United States are subject to
foreign regulatory requirements that vary widely from country to country. The
time required to obtain approvals required by foreign countries may be longer
or shorter than that required for FDA approval, and requirements for licensing
may differ from FDA requirements. Failure to comply with foreign regulatory
requirements also could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--
Government Regulation."

UNCERTAIN AVAILABILITY OF THIRD PARTY REIMBURSEMENT; POSSIBLE HEALTH CARE RE-
FORMS
 
In the United States, suppliers of health care products and services are
greatly affected by Medicare, Medicaid and other government insurance programs,
as well as by private insurance reimbursement programs. Third party payers may
affect the pricing or relative attractiveness of the Company's products by
regulating the maximum amount of reimbursement provided for by such payers to
the physicians and clinics using the Company's devices, or any other products
that the Company may develop, or by taking the position that such reimbursement
is not available at all. The level of reimbursement by third party payers in
those states that do provide reimbursement varies considerably. Major third
party payers reimburse inpatient medical treatment, including all operating
costs and all furnished items or services, including devices such as the
Company's, at a prospectively fixed rate based on the diagnosis-related group
("DRG") that covers such treatment as established by the federal Health Care
Financing Administration. For interventional procedures, the fixed rate of
reimbursement is based on the procedure or procedures performed and is
unrelated to the specific devices used in such procedure. The amount of profit
realized by suppliers of health care services relating to the procedure may be
reduced by the use of the Company's devices. If a procedure is not covered by a
DRG, certain third party payers may deny reimbursement. Alternatively, a DRG
may be assigned that does not reflect the costs associated with the use of the
Company's devices, resulting in limited reimbursement. If, for any reason, the
Company's products were not to be reimbursed by third party payers, the
Company's ability to sell its products may be materially adversely affected.
Mounting concerns about rising health care costs may cause more restrictive
coverage and reimbursement policies to be implemented in the future. Several
states and the federal government are investigating a variety of alternatives
to reform the health care delivery system and further reduce and control health
care spending. These reform efforts include proposals to limit spending on
health care items and services, limit coverage for new technology and limit or
control directly the price health care providers and drug and device
manufacturers may charge for their services and products. In the international
market, reimbursement by private third party medical insurance providers, and
governmental insurers and providers varies from country to country. In certain
countries, the Company's ability to achieve significant market penetration may
depend upon the availability of third party governmental reimbursement. See
"Business--Government Regulation."
 
UNCERTAINTIES OF SUCCESSFUL REDESIGN OF THE SEPTAL REPAIR DEVICE
 
Between 1989 and 1991 Bard sponsored trials of an earlier version of the septal
repair device, known as the Clamshell. In 1991, Bard discovered fractures of
the stainless steel framework in certain of the devices implanted during such
clinical trials and, following such discovery, suspended its clinical trials
worldwide except for patients at high risk for surgery. It was determined that
the fractures were caused by metal fatigue resulting from higher than
anticipated forces acting on the Clamshell. Redesign efforts were initiated,
resulting in the design of the current version of the septal repair device.
Although the CardioSeal Septal Occluder has undergone in vitro testing, there
can be no assurance that such testing accurately simulates the actual forces in
the human body or that similar fractures will not occur with the CardioSeal
Septal Occluder. If such fractures occur, the Company's efforts to
commercialize the CardioSeal Septal Occluder may be significantly delayed and
the Company may be required to invest significant resources in further
designing and engineering the device or to discontinue its development efforts.
See "Business--Products."
 
PRODUCT LIABILITY RISKS; INSURANCE
 
The testing, marketing and sale of implantable devices and materials entail an
inherent risk that product liability claims will be asserted against the
Company or its third party distributors in the event that the use of the
Company's devices is alleged to have adverse effects on a patient. A product
liability claim or a product recall could have a material adverse effect on the
Company's business, financial condition and results of operations. Certain of
the Company's devices are designed to be used in life-threatening situations
where there is a high risk of serious injury or death. Although the Company
currently maintains limited product liability insurance coverage, there can be
no assurance that in the future the Company will be able to maintain such
coverage on acceptable terms or that current insurance or insurance
subsequently obtained will provide adequate coverage against any or all
potential claims. Furthermore there can be no assurance that the Company will
avoid significant product liability claims and the attendant adverse publicity.
Any product liability claim or other claim with respect to uninsured or
underinsured liabilities could have a material adverse effect on the Company's
business, financial condition, and result of operations. See "Business--Product
Liability and Insurance."

UNCERTAIN FUTURE CAPITAL REQUIREMENTS
 
The Company may require funds in addition to the net proceeds of the Offering
for its research and product development programs, preclinical and clinical
testing, operating expenses, regulatory processes and manufacturing and
marketing programs. The Company may seek such additional funding through public
or private financing or collaborative, licensing or other arrangements with
corporate partners. If additional funds are raised by issuing equity
securities, further dilution to existing stockholders will result and future
investors may be granted rights superior to those of existing stockholders;
debt financing, if available, may involve restrictive covenants. The Company's
capital requirements will depend on numerous factors, including the sales of
its products, the progress of its research and development programs, the
progress of preclinical and clinical testing, the time and cost involved in
obtaining regulatory approvals, the cost of filing, prosecuting, defending and
enforcing any patent claims and other intellectual property rights, competing
technological and market developments, developments and changes in the
Company's existing research, licensing and other relationships and the terms of
any new collaborative, licensing and other arrangements that the Company may
establish. See "Business--Licensed Technology; Royalty Obligations,"
"Management-Employment Agreements" and "Certain Transactions." The Company's
cash requirements will vary from those now planned and such variances may be
material.
 
There can be no assurance that additional financing will be available when
needed or, if available, will be available on acceptable or affordable terms.
Insufficient funds may prevent the Company from implementing its business
strategy or may require the Company to delay, scale back or eliminate certain
of its research and product development programs or to license to third parties
rights to commercialize products or technologies that the Company would
otherwise seek to develop itself. See "Management Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources."
 
DEPENDENCE ON QUALIFIED PERSONNEL
 
There is intense competition for qualified personnel in the medical device
field, and there can be no assurance that the Company will be able to continue
to attract and retain qualified personnel necessary for the development of its
business. The loss of the services of existing personnel as well as the failure
to recruit additional qualified scientific, technical and managerial personnel
in a timely manner would be detrimental to the Company's anticipated growth and
expansion into areas and activities requiring additional expertise such as
marketing. The failure to attract and retain such personnel could adversely
affect the Company's business. See "Business--Employees" and "Management."
 
NO PRIOR PUBLIC MARKET; POTENTIAL VOLATILITY OF STOCK PRICE
 
Prior to the Offering, there has been no public market for the Company's Common
Stock and there can be no assurance that an active public market for the
Company's Common Stock will develop or be sustained in the future. The initial
public offering price of the Common Stock will be determined by negotiations
between the Company and the Underwriters. See "Underwriting" for a discussion
of the factors to be considered in determining the initial public offering
price. In addition, the market price of the Common Stock is likely to be highly
volatile as frequently occurs with publicly traded emerging growth companies
and medical device companies. Factors such as results of clinical trials,
announcements of technological innovations or new products by the Company or
its competitors, government regulatory action affecting the Company's proposed
products in either the United States or foreign countries, developments or
disputes concerning patent or proprietary rights and market conditions for
emerging growth and medical device companies in general, as well as period-to-
period fluctuations in the Company's financial results, could have a
significant impact on the market price of the Common Stock.
 
BROAD DISCRETION AS TO USE OF PROCEEDS
   
Approximately 35% of the estimated net proceeds of the Offering has been
allocated to working capital and other general corporate purposes and will be
used for such specific purposes as management may determine, including
potential license or acquisition arrangements with other companies. The Company
is currently evaluating certain potential license or acquisition opportunities;
however, the Company has no agreements, arrangements or understandings with any
third parties for any such licenses or acquisitions at this time. There can be
no assurance that the Company will enter into or consummate any such license or
acquisition or, if entered into, that any such arrangements will be successful.
Accordingly, management will have broad discretion with respect to the
expenditure of a substantial portion of the net proceeds of the Offering. See
"Use of Proceeds."     
 
                                       11

AVAILABILITY OF PREFERRED STOCK FOR ISSUANCE
 
In addition to its authorized shares of Common Stock, the Company's Amended and
Restated Certificate of Incorporation authorizes the issuance of up to
3,000,000 shares of undesignated preferred stock. Upon completion of the
Offering, no shares of preferred stock of the Company will be outstanding, and
the Company has no present intention to issue any shares of preferred stock.
However, because the rights and preferences of any series of preferred stock
may be set by the Board of Directors in its sole discretion, the rights and
preferences of any such preferred stock may be superior to those of the Common
Stock and thus may adversely affect the rights of the holders of Common Stock.
See "Description of Capital Stock--Preferred Stock."
 
POSSIBLE ADVERSE EFFECT OF SHARES ELIGIBLE FOR FUTURE SALES
 
Upon completion of the Offering, the Company's existing stockholders will
beneficially own an aggregate of 6,285,922 shares of Common Stock. Sales of
substantial amounts of Common Stock in the public market by such persons after
the Offering could adversely affect prevailing market prices for the Common
Stock. At July 31, 1996, 281,520 shares of Common Stock were issuable upon
exercise of outstanding warrants at a weighted average exercise price of $3.34
per share and 1,701,390 shares of Common Stock were issuable upon exercise of
outstanding stock options at a weighted average exercise price of $2.50 per
share. The Company, certain stockholders and directors and officers of the
Company have agreed to enter into lock-up agreements with the Underwriters not
to dispose of any shares of Common Stock, nor any securities convertible into
or exchangeable or exercisable for any such shares, without the prior written
consent of J.P. Morgan Securities Inc. for a period of 180 days after the
Offering, subject to certain limited exceptions. After such 180-day period,
however, substantially all shares of Common Stock currently outstanding will be
eligible for sale in the public market pursuant to Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), if the conditions to
that Rule have been met. The Company's current stockholders are also entitled
to certain rights with respect to the registration under the Securities Act of
shares held by them. See "Management," "Description of Capital Stock--
Registration Rights" and "Shares Eligible for Future Sale."
 
NO DIVIDENDS
 
The Company does not anticipate declaring or paying cash dividends in the
foreseeable future. The Company expects that any earnings which it may realize
will be retained for use in its business. See "Dividend Policy."
 
DILUTION
   
Investors purchasing shares of Common Stock in the Offering will incur
immediate dilution of $7.24 in the per share net tangible book value of their
Common Stock (assuming an initial public offering price of $10.50). The Company
has granted to officers, directors, certain principal stockholders and others
numerous options and warrants to purchase Common Stock at prices below the
offering price. Investors purchasing shares of Common Stock in the Offering
will incur additional dilution to the extent outstanding warrants and options
are exercised. See "Dilution," "Management--Options Granted Outside of the
Plans" and "Certain Transactions."     
 
                                USE OF PROCEEDS
   
The net proceeds to the Company from the Offering are estimated to be
approximately $28.6 million, assuming an initial public offering price of
$10.50 per share ($33.0 million if the over-allotment option is exercised in
full), after deducting the underwriting discount and offering expenses payable
by the Company.     
   
The Company will use approximately $4.5 million of the net proceeds for the
Redemption of the Company's Redeemable Preferred Stock, $.001 par value per
share ("Redeemable Preferred Stock"), including the payment of accrued
dividends. See "Certain Transactions." The Company anticipates that it will use
approximately $8.0 million of the net proceeds for research, development,
clinical trials and regulatory matters; approximately $3.0 million to develop
the Company's sales and marketing capabilities; and approximately $3.0 million
for leasehold improvements and payments under certain equipment lease financing
obligations to be incurred in connection with the Company's relocation to a new
manufacturing, laboratory and administrative facility. The Company intends to
use the balance of the net proceeds, approximately $10.1 million, for potential
licenses and acquisitions of technologies or products that complement the
business of the Company and for other general corporate purposes, including
working capital. As of the date of this Prospectus, the Company is evaluating
certain potential license or acquisition opportunities; however, the Company
has no agreements, arrangements or understandings with any third parties for
any such licenses or acquisitions. Pending such uses, the Company intends to
invest the net proceeds of the Offering in interest-bearing, investment grade
securities.     
 
                                       12
<PAGE>
 
The foregoing represents the Company's best estimate of its allocation of the
net proceeds from the sale of the Common Stock offered hereby based upon the
current state of its business operations, its current plans and current
economic and industry conditions and is subject to reallocation among the
categories listed above or to new categories. The amounts actually expended for
each purpose may vary significantly depending upon numerous factors, including
the progress of the Company's clinical trials and actions relating to
regulatory matters, and the costs and timing of expansion of marketing, sales
and manufacturing activities, and hence the Company's management will retain
broad discretion in the allocation of a substantial portion of the net
proceeds. See "Risk Factors--Broad Discretion as to Use of Proceeds."
 
                                DIVIDEND POLICY
 
From the Company's inception through October 19, 1995, the Company was an "S"
corporation for federal and state income tax purposes. As such, the Company
generally was not subject to federal or state income taxes, but its income was
taxable to its stockholders. The Company declared and paid dividends in the
aggregate amount of $600,000 for such period.
 
The Company does not anticipate declaring or paying cash dividends in the
foreseeable future. The Company expects that any earnings which it may realize
will be retained for use in its business.
 
                                 CAPITALIZATION
   
The following table sets forth as of June 30, 1996 (i) the pro forma
capitalization of the Company which gives effect to the Conversion, and (ii)
the pro forma capitalization as adjusted to give effect to the sale of the
shares of Common Stock offered hereby at an assumed offering price of $10.50
per share (after deducting the underwriting discount and offering expenses
payable by the Company) and the application of a portion of the net proceeds
therefrom for the Redemption. See "Use of Proceeds." This table should be read
in conjunction with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and the Consolidated Financial Statements
and the Notes thereto included elsewhere in this Prospectus.

                                    DILUTION
 
Dilution is the amount by which the initial public offering price paid by the
purchasers of the shares of Common Stock will exceed the net tangible book
value per share of Common Stock after the Offering. Net tangible book value per
share is determined at any date by subtracting the total liabilities of the
Company from the total book value of the tangible assets of the Company and
dividing the difference by the number of shares of Common Stock deemed to be
outstanding at such date.
   
The net tangible book value of the Company as of June 30, 1996 was $1,893,778
or $.30 per share pro forma after giving effect to the Conversion. After giving
effect to the sale of 3,000,000 shares of Common Stock offered by the Company
hereby at an assumed initial public offering price of $10.50 per share and the
application of a portion of the estimated net proceeds therefrom for the
Redemption, the pro forma net tangible book value of the Company as of June 30,
1996 would have been $30,314,334 or $3.26 per share. This represents an
immediate increase in net tangible book value of $2.96 per share to existing
stockholders and an immediate dilution of $7.24 per share to new investors
purchasing the shares of Common Stock in the Offering. The following table
illustrates the dilution of a new investor's equity on a per share basis as of
June 30, 1996:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
The following discussion of the financial condition and results of operations
of the Company should be read in conjunction with the Consolidated Financial
Statements and the Notes thereto included elsewhere in this Prospectus.
 
OVERVIEW
 
Since its inception in 1986, the Company has focused its efforts on the design,
development and commercialization of medical devices which are delivered by
minimally invasive procedures. The products developed or under development
include self-expanding stents, vena cava filters and septal repair devices.
 
The Company's initial product, a vena cava filter system, was given FDA
clearance in 1990. This product is distributed in the United States and certain
other countries by Bard Radiology and in other markets outside the United
States by Bard International. Both distributors are obligated to make annual
minimum purchases. The filter component of the current vena cava filter system
is manufactured by Lake Region Manufacturing Inc. ("Lake Region"). The Company
currently purchases its delivery systems for the vena cava filter under
purchase orders with third party suppliers. The vena cava filter is the only
product sold by the Company during the periods discussed below. The majority of
the Company's revenues, and all of its cost of product sales, are related to
the vena cava filter during such periods.
 
In November 1994, the Company entered into an agreement with Boston Scientific
pursuant to which Boston Scientific obtained exclusive worldwide rights to
develop, manufacture, market and distribute the Company's stent technology and
products which incorporate such technology. Under this license agreement,
Boston Scientific is responsible for performing clinical trials for stents
under development and for reimbursing the Company for stent development costs
incurred by the Company. These reimbursements are classified as product
development revenues in the Consolidated Statement of Operations. The Company
also receives license fees, including milestone payments, from Boston
Scientific under this license agreement. Upon commercialization, the Company
will receive royalties based upon product sales and certain manufacturing cost
reduction incentives from Boston Scientific under the license agreement. The
Company's revenues in the periods discussed below include such license fees and
reimbursements. Most of its costs associated with its stents are included in
research and development expenses.
 
In February 1996, the Company acquired, through the issuance of Common Stock,
the rights to develop and commercialize its septal repair device. The Company
has not yet realized any revenue related to its septal repair device. The
Company expects to manufacture this device itself which will result in
increased operating expenses as discussed below.
 
In the first half of 1996 the Company significantly increased the scope of its
operations. This included the addition of a new Chief Executive Officer, an
Executive Vice President and Chief Financial Officer and a President of the
Septal Repair Division, which was formed in February 1996. In addition, in
April 1996, the Company entered into a lease for a new manufacturing,
laboratory and administrative space which will increase the Company's annual
facility lease payments by approximately $400,000. The Company anticipates
taking full occupancy in September 1996 upon completion of construction of the
facility to the Company's specifications. The Company expects operating
expenses to continue to increase significantly as it enters into clinical
trials for the septal repair device, accelerates its other product development
programs and builds the infrastructure necessary to commercialize its
technologies.
 
The Company has agreed to make certain royalty payments to Children's Medical
Center Corporation based on net sales of the CardioSeal Septal Occluder. The
Company has also agreed to pay certain royalties to Morris Simon, M.D., the
Company's Scientific Director and co-founder, based on sales of products using
the technology invented by Dr. Simon relating to the SNF. In addition, pursuant
to the Company's employment agreements with Mr. Kleshinski and Dr. Harry,
respectively, the Company has agreed to pay certain royalties based on sales or
licenses of products where either Mr. Kleshinski or Dr. Harry, as the case may
be, was the sole or joint inventor. See "Management--Employment Agreements" and
Note 8(d) of Notes to the Consolidated Financial Statements.

RESULTS OF OPERATIONS
 
SIX MONTHS ENDED JUNE 30, 1996 COMPARED WITH SIX MONTHS ENDED JUNE 30, 1995
 
Revenues. Revenues for the six months ended June 30, 1996 increased to $2.7
million from $1.6 million for the six months ended June 30, 1995 (a 69%
increase). Product sales derived from the sale of vena cava filters increased
to $2.0 million for the six months ended March 31, 1996 from $1.3 million for
the six months ended June 30, 1996 (a 54% increase). The increase in product
sales was primarily due to increased unit sales of vena cava filters, which in
turn, was primarily due to the introduction of the straight-line delivery
system in November 1995, and the commencement of international distribution by
Bard International in January 1996. The Company recorded $625,000 in license
fees from Boston Scientific related to its stent technology in the six months
ended June 30, 1996, consisting of a $250,000 milestone payment and the first
two quarters minimum royalty payments of $187,500 each. Product development
revenues from Boston Scientific (which consist of reimbursement of certain
costs incurred by the Company) decreased to $79,000 for the six months ended
June 30, 1996 from $269,000 for the six months ended June 30, 1995 (a 71%
decrease), due to the completion of the Company's transfer of its stent
technology to Boston Scientific in November 1995 which has resulted in a
reduction of stent development costs incurred by the Company on behalf of
Boston Scientific.
 
Cost of Product Sales. Cost of product sales increased to $924,000 for the six
months ended June 30, 1996 from $546,000 for the six months ended June 30, 1995
(a 69% increase). The cost of product sales in both periods was entirely
related to vena cava filters, and the increase reflects the increase in vena
cava filters sold in the six months ended June 30, 1996. Cost of products
sales, as a percent of product sales, increased to 46% for the six months ended
March 31, 1996 from 42% for the six months ended June 30, 1995. This increase
reflects the impact of the introduction of the straight-line delivery system
which has a higher unit manufacturing cost as a percent of the selling price.
 
Research and Development. Research and development expense increased to $1.2
million for the six months ended June 30, 1996 from $366,000 for the six months
ended June 30, 1995 (a 228% increase). The increase reflects increased activity
in the Company's development programs for vena cava filters, the CardioSeal
Septal Occluder and other products under development. Increased expenses
resulted primarily from increases in personnel and related costs, engineering
expenses and facilities related costs. The Company received reimbursement from
Boston Scientific for $79,000 and $269,000 of these expenses in the six months
ended June 30, 1996 and 1995 respectively, which amounts are included in
revenues.
 
General and Administrative. General and administrative expenses increased to
$937,000 for the six months ended June 30, 1996 from $279,000 for the six
months ended June 30, 1995 (a 236% increase). The increase consisted primarily
of increases in personnel and related costs, legal and professional fees and
consulting expenses. These increases resulted from the Company's expanded scope
of operations.
 
Selling and Marketing. Selling and marketing expenses increased to $103,000 for
the six months ended June 30, 1996 from $65,000 for the six months ended June
30, 1995 (a 58% increase). The increase related primarily to the introduction
of the straight-line delivery system and the international distribution of the
vena cava filter by Bard International beginning in January 1996, and
secondarily to pre-marketing activities related to the CardioSeal Septal
Occluder. Selling and marketing expenses for the six months ended June 30, 1995
were entirely related to vena cava filters.
 
In-Process Research and Development. For the six months ended June 30, 1996,
the Company recorded a charge of $1.1 million for in-process research and
development related to the CardioSeal Septal Occluder which was acquired in
February 1996. See Note 3 of Notes to the Consolidated Financial Statements.
 
Interest Income (Expense), Net. Interest income, net was $101,000 for the six
months ended June 30, 1996 as compared to interest expense, net amounting to
$11,000 for the six months ended June 30, 1995. This increase was primarily due
to the receipt in February 1996 of $7.5 million in net proceeds from the sale
of Convertible Preferred Stock. Interest expense in both periods consisted
primarily of interest on subordinated debt to stockholders, which was fully
repaid in April 1996.
 
Income Taxes. The Company had no income tax provision for the six months ended
June 30, 1996 as it incurred an operating loss. Prior to October 19, 1995, the
Company elected to be taxed as a "S" Corporation for federal and state
 
                                       17
<PAGE>
 
income tax purposes and, accordingly, the financial statements do not include a
provision for income taxes for the six months ended June 30, 1995. The Company
has not recorded a pro forma tax provision as there would have been sufficient
net operating loss carryforwards to offset income in all periods presented. See
Note 4 to the Consolidated Financial Statements.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED WITH YEAR ENDED DECEMBER 31, 1994
 
Revenues. Revenues increased to $3.8 million in 1995 from $2.6 million in 1994
(a 46% increase). Product sales of vena cava filters increased to $2.7 million
in 1995 from $1.8 million in 1994 (a 50% increase). This increase is primarily
due to increased unit sales of vena cava filters which the Company attributes
primarily to the distribution agreements with Bard. License fees, which consist
of payments from Boston Scientific related to the Company's stent technology,
decreased to $625,000 in 1995 from $773,000 in 1994 (a 19% decrease). License
fees in 1995 represent amounts received upon the achievement of a contractual
milestone. License fees in 1994 represented initial license fees received from
Boston Scientific upon entering into the license agreement in November 1994.
Product development revenues increased to $492,000 in 1995 from $38,000 in
1994. The significant increase in 1995 reflects a full year of development
efforts funded by Boston Scientific under the agreements entered into in
November 1994.
 
Cost of Product Sales. Cost of product sales increased to $1.3 million in 1995
from $812,000 in 1994 (a 60% increase). The increase in cost of product sales
reflects the increase in vena cava filter units sold in 1995. Cost of product
sales, as a percent of product sales, increased to 47% in 1995 from 44% in 1994
primarily due to the introduction of the vena cava straight-line delivery
system in November 1995, which has a higher unit manufacturing cost as a
percent of the selling price.
 
Research and Development. Research and development expenses increased to
$871,000 in 1995 from $555,000 in 1994 (a 57% increase). The increase reflects
increased product development and patent registration costs associated with the
development of the Company's stent technology which was licensed to Boston
Scientific in November 1994. Increased expenses resulted primarily from
increases in personnel, engineering expenses and facilities related costs. The
Company received reimbursement from Boston Scientific for $492,000 and $38,000
of these expenses in 1995 and 1994, respectively, which amounts are included in
revenues.
 
General and Administrative. General and administrative expenses increased to
$871,000 in 1995 from $770,000 in 1994 (a 13% increase). The increase is
primarily due to the expansion of the Company's infrastructure necessary to
support the growth of the Company and increases in product development
activities. Increased expenses consisted primarily of increases in personnel
and related costs and consulting expenses.
 
Selling and Marketing. Selling and marketing expenses decreased to $169,000 in
1995 from $182,000 in 1994 (a 7% decrease). Selling and marketing expenses in
1995 and 1994 are entirely related to the Company's vena cava filter.
 
Interest Income (Expense), Net. Interest expense, net decreased to $29,000 in
1995 from $39,000 in 1994 (a 26% decrease). The decrease reflects the repayment
of subordinated debt to stockholders. Interest income in 1995 and 1994 was not
significant.
 
YEAR ENDED DECEMBER 31, 1994 COMPARED WITH YEAR ENDED DECEMBER 31, 1993
 
Revenues. Revenues increased to $2.6 million in 1994 from $2.0 million in 1993
(a 30% increase). Product sales decreased to $1.8 million in 1994 from $2.0
million in 1993 (a 10% decrease). The decrease in product sales was due
primarily to a decrease in the sales price of such filters received by the
Company, as a result of the distribution agreement with Bard Radiology, offset
in part by increased unit sales. In 1992 the Company entered into its exclusive
distribution agreement with Bard Radiology, pursuant to which it receives a
specified percentage of the average selling price of the vena cava filter. This
percentage decreased in August 1993 from its introductory level and then again
in October 1994, to its current level under the agreement. The Company does not
anticipate any additional reductions under the terms of the agreement in the
near future. License fees were $773,000 in 1994. The Company had no license fee
revenue in 1993. License fees represent initial license fees received from
Boston Scientific upon entering into the license agreement in November 1994.
Product development revenues were $38,000 in 1994. The increase reflects
development efforts funded by Boston Scientific under the agreement entered
into in November 1994.
 
 
                                       18
<PAGE>
 
Cost of Product Sales. Cost of product sales increased to $812,000 in 1994,
from $655,000 in 1993 (a 24% increase). The increase in cost of product sales
reflects the increase in vena cava filter units sold. Cost of product sales, as
a percent of product sales, increased to 44% in 1994 as compared to 33% in 1993
primarily due to the impact of the contractual reduction in the unit selling
price of vena cava filters.
 
Research and Development. Research and development expenses increased to
$555,000 in 1994 from $272,000 in 1993 (a 104% increase). The increase reflects
increased product development and patent registration costs associated with the
development of the Company's stent technology which was licensed to Boston
Scientific in November 1994. Increased expenses consisted primarily of
increases in personnel, engineering expenses and facilities related costs. The
Company received reimbursement from Boston Scientific for $38,000 of these
expenses in 1994, which amount is included in revenues.
 
General and Administrative. General and administrative expenses increased to
$770,000 in 1994 from $468,000 in 1993 (a 65% increase). The increase is
primarily due to the expansion of the Company's infrastructure necessary to
support the growth of the Company and increases in product development
activities. Increased expenses consisted primarily of increases in personnel
and related costs and consulting expenses.
 
Selling and Marketing. Selling and marketing expenses decreased to $182,000 in
1994 from $285,000 in 1993 (a 36% decrease). Selling and marketing expenses in
1994 and 1993 are primarily related to the Company's vena cava filter. The
decrease reflects the Company's decision in 1993 to discontinue selling the
filter through independent distributors and begin distributing exclusively
through Bard.
 
Interest Income (Expense), Net. Interest expense, net decreased to $39,000 in
1994 from $62,000 in 1993 (a 37% decrease). The decrease in 1994 reflects the
repayment of a portion of the subordinated debt due to stockholders. Interest
income in 1994 and 1993 was not significant.
 
LIQUIDITY AND CAPITAL RESOURCES
 
The Company has funded its operations primarily through cash flows from
operations of $525,000, $1.2 million and $647,000 in the years ended December
31, 1995, 1994 and 1993, respectively. In the six months ended June 30, 1996,
operations utilized cash of $1,092,000 of which part was used to fund a portion
of the acquisition of the septal repair device technology and for working
capital. Cash flows from operations include $500,000 of upfront license fees
and a $100,000 advance product development billing received from Boston
Scientific in 1994 and recorded as deferred revenue. Cash flow from operations
was used to fund increases in accounts receivable of $238,000 and $282,000 in
the year ended December 31, 1995 and the six months ended June 30, 1996,
respectively. Such increases reflect the increases in product sales and the
timing of such product sales. In February 1996, the Company received
approximately $7.5 million in net proceeds from the sale of 3,787,104 shares of
Convertible Preferred Stock, which funds were used in part to accelerate its
facilities and infrastructure expansion. In the year ended December 31, 1994
and the six months ended June 30, 1996, the Company made distributions to its
stockholders of $500,000 and $100,000, respectively. In 1994, the Company began
repaying a $1.5 million loan received in 1992 from Bard. Loan payments are
based upon the number of domestic vena cava units sold to Bard Radiology. The
loan is expected to be fully repaid by the end of 1996. Payments during 1994,
1995 and the six months ended June 30, 1996 amounted to $242,000, $477,000 and
$382,000, respectively. In addition, during the years ended December 31, 1993,
1994, 1995 and the six months ended June 30, 1996, the Company repaid
subordinated debt to its stockholders amounting to $184,000, $329,000, $2,500,
and $309,000, respectively.
 
Purchases of property and equipment for use in its research and development and
general and administrative activities amounted to $336,000 during the three
years ended December 31, 1995 and $275,000 during the six months ended June 30,
1996. In May 1996, the Company entered into a lease for a new manufacturing
research and administrative facility which is expected to increase its annual
facility lease payments by approximately $400,000 beginning in the third
quarter of 1996. The Company anticipates incurring costs during 1996 and 1997
for leasehold improvements for its new facility of approximately $1.4 million,
net of the landlord's contribution, and for purchases of equipment and
furniture of approximately $1.5 million. The Company has received a $1.5
million firm commitment for financing substantially all of the equipment and
furniture. The Company anticipates incurring additional leasehold improvements
and purchases of equipment and furniture.

<PAGE>
 
The Company is party to various other substantial contractual arrangements
including salaries and fees for current employees and consultants which are
likely to increase as additional agreements are entered into and additional
personnel are retained. The Company has also committed to purchase certain
minimum quantities of the vena cava filter from a supplier through June 2001.
See Note 8(a) of Notes to the Consolidated Financial Statements. All of these
arrangements require cash payments by the Company over varying periods of time.
Certain of these arrangements are cancelable on short notice and certain
require termination or severance payments as part of any early termination.
 
The Company believes that the anticipated net proceeds of the Offering, its
existing resources and cash flow from current operations will be sufficient to
fund its current level of operations and planned new product development,
including increased working capital requirements and capital expenditures, for
the foreseeable future. The Company expects to accelerate its product
development, marketing and other activities with the proceeds of the Offering.
The Company has incurred a net loss of $1.4 million for the six months ended
June 30, 1996, primarily as a result of a charge of $1.1 million for acquired
in-process research and development. See Note 3 of Notes to the Consolidated
Financial Statements. The Company expects operating losses to continue at least
through early 1997 as it continues to expend substantial resources to complete
development of the Company's products, seek regulatory clearances or approvals,
build its marketing, sales and manufacturing organizations and conduct further
research and development.
 
The Company may require funds in addition to the net proceeds of the Offering
for its research and product development programs, preclinical and clinical
testing, operating expenses, regulatory processes, manufacturing and marketing
programs and potential licenses and acquisitions. Any additional equity
financing may be dilutive to stockholders, and debt financing, if available,
may involve restrictive covenants. The Company's capital requirements will
depend on numerous factors, including the sales of its products, the progress
of its research and development programs, the progress of preclinical and
clinical testing, the time and cost involved in obtaining regulatory approvals,
the cost of filing, prosecuting, defending and enforcing any patent claims and
other intellectual property rights, competing technological and market
developments, developments and changes in the Company's existing research,
licensing and other relationships and terms of any collaborative, licensing and
other arrangements that the Company may establish.

OVERVIEW
 
The Company designs, develops, and markets innovative medical devices that
utilize advanced materials and are delivered by minimally invasive procedures.
The Company's products offer alternative approaches to complex medical
treatments, thereby reducing patient trauma, shortening procedure,
hospitalization and recovery times, and lowering overall treatment costs. The
Company's patented medical devices include self-expanding stents, vena cava
filters (the Simon Nitinol Filter) and septal repair devices (the CardioSeal
Septal Occluder). The Company's strategy is to develop and commercialize a
broad range of advanced medical devices for minimally invasive applications to
address unmet medical needs. At this time, the Company's stents are in European
clinical trials for certain indications, its vena cava filters are marketed in
the United States and abroad, and the Company is completing development of its
septal repair device.
 
The Company has established arrangements with Boston Scientific and Bard,
worldwide leaders in sales of minimally invasive medical devices, for the
distribution, sale and marketing of its stents and its Simon Nitinol Filter,
respectively. The Company intends to continue to market products with extensive
distribution requirements through collaborations with established market
leaders. NMT intends to develop direct marketing and distribution capabilities
for products with smaller and more easily accessible user groups (such as the
CardioSeal Septal Occluder).
 
BACKGROUND
 
The Company was founded in July 1986 to develop and commercialize medical
devices using nitinol. Dr. Morris Simon, the Company's Scientific Director and
co-founder, was one of the first medical researchers to investigate the use of
nitinol for medical device applications. In April 1990, the Company obtained
FDA clearance to market its initial product, the Simon Nitinol Filter, in the
United States. The Company entered into an exclusive distribution agreement
with Bard Radiology for distribution of the SNF in the United States and
certain other countries in May 1992. The Company's primary stent patent was
issued in November 1994 and, during the same month, the Company entered into an
exclusive license agreement with Boston Scientific to further develop,
manufacture, market and distribute NMT's stents worldwide. In November 1995,
the Company expanded its relationship with Bard by granting Bard International
the right to distribute the SNF in most markets outside the United States. In
February 1996, the Company acquired the rights to its CardioSeal Septal
Occluder to complement the Company's core technologies and expand its product
base. See "Certain Transactions."
 
CORE TECHNOLOGIES
 
NMT has developed an expertise in precisely engineering nitinol and other
advanced materials, such as MP35N, for a variety of innovative medical device
applications. The Company has developed capabilities in advanced device
fabrication, materials characterization, manufacturing and process control and
sophisticated in vitro testing resulting in highly efficient and reliable
manufacturing processes.
 
Nitinol, a nickel-titanium alloy, has unique superelastic and thermal shape-
memory characteristics. The superelastic characteristics enable a nitinol-based
device to undergo severe deformation without permanent damage to either its
shape or strength. The thermal shape-memory characteristics of nitinol enable a
device which has been radically deformed to return to its intended shape in
response to a small change in temperature. The mechanical properties that can
be engineered into nitinol-based devices permit innovative product designs that
presently would be difficult or impossible to replicate with other materials.
The Company utilizes both the superelastic and thermal shape-memory
characteristics of nitinol for medical device applications. The Company has
demonstrated its ability to utilize these characteristics to provide for ease
of access and delivery of sophisticated medical devices that transform into
their intended shape once placed into the body. Nitinol is biocompatible and
non-ferromagnetic, thereby allowing the use of magnetic resonance imaging on
patients with nitinol-based device implants.
 
MP35N is an advanced metal alloy which is biocompatible and resistant to
corrosion and fatigue. The Company has combined the use of MP35N with knitted
polyester in developing the CardioSeal Septal Occluder. Knitted polyester, a
biocompatible fabric that encourages tissue in-growth, has been extensively
used in the vasculature for many years.

PRODUCTS
 
Stents
 
Stents are small tubes that hold open arteries, veins and other passageways in
the body, such as the esophagus and bile duct, that have closed or become
obstructed as a result of disease, trauma, or aging. Stents are placed in the
body using catheter-based delivery systems in minimally invasive procedures.
Once deployed, they exert radial force against the walls of passageways to
enable such passageways to remain open and functional. A number of different
stent designs, materials and delivery systems, with varying characteristics are
currently available. The three most prevalent stent designs are slotted tubes
(a metal tube from which most of the material is removed, resulting in a
lattice-like structure), coiled stents (continuous coiled wire) and wire mesh
stents (knitted metal wire). Most stents are currently manufactured using
stainless steel or similar alloys and are deployed through the expansion of a
balloon on a catheter-based delivery system. After deployment, a second balloon
may be used to further expand the stent. Certain stents, including the
Company's, are self-expanding, thereby eliminating the need for a balloon on
the delivery catheter. The factors influencing the performance of a stent
include ease of deployment, radial strength, flexibility, stability and the
ability to achieve precise placement.
 
Stents have emerged as one of the fastest growing segments of the medical
device market and are used increasingly as adjuncts or alternatives to a
variety of medical procedures because it is believed that they are beneficial
to overall patient outcome and may, over time, reduce total treatment costs.
 
Stents are increasingly being used in connection with the treatment of
atherosclerosis, a vascular disease characterized by the deposit of fatty
substances (plaque) in the interior walls of blood vessels. The accumulation of
plaque narrows the blood vessels, thereby reducing blood flow. Accumulation of
atherosclerotic plaque in the vessels of the heart can result in narrowing or
blockage of the arteries that provide blood flow to the heart, causing chest
pain (angina pectoris) and heart attacks. Atherosclerosis in the peripheral
vessels can cause a narrowing or blockage of the vessels that provide blood to
the legs, causing pain and cramps, and possible tissue damage, which in severe
cases can result in amputation. Atherosclerotic plaque in the carotid arteries,
located near the surface of the neck, can cause a narrowing of the vessels that
provide the primary blood flow to the brain, causing dizzy spells, "mini
strokes" known as transient ischemic attacks (TIA's) and strokes.
 
                                       22
<PAGE>
 
Balloon dilation (angioplasty) of the coronary and peripheral arteries has
become one of the most common minimally invasive procedures performed
worldwide. The effectiveness of angioplasty has been limited by the relatively
high rate of reclosure of the treated vessels (restenosis) during the first
several months after dilation. Therefore, the use of stents in conjunction with
angioplasty is increasingly becoming an accepted practice to reduce the
incidence of restenosis. Advanced carotid artery disease is currently generally
treated by invasive surgery (endarterectomy). Angioplasty with stenting is
being used on an experimental basis as a minimally invasive alternative to
surgery in the carotid arteries.
 
Injury, disease, birth defect or trauma can cause a weakening of a section of
an arterial wall that can result in a bulge in the artery called an aneurysm,
which if ruptured can lead to death. One of the most common of these aneurysms
is an abdominal aortic aneurysm ("AAA"). Current treatment of AAA requires
highly invasive surgery. Stent grafts using catheter-based delivery systems are
currently being performed on an experimental basis.
 
Stents are also being used for palliative treatment of certain cancers. During
the later stages of esophageal cancer, for example, patients often develop a
narrowing of the esophagus due to tumor ingrowth. This narrowing inhibits the
ability to swallow. These strictures are now treated most often with painful
dilations or laser ablation. Pancreatic cancer often results in a narrowing of
the bile duct due to tumor ingrowth. The patient can become jaundiced and
develop fever. Current treatment for tumor ingrowth of the bile duct includes
the use of plastic and self-expanding metal mesh stents.
 
NMT's Hex-cell Stents. The Company has developed and patented a nitinol stent
which relies on a novel hexagonal cell (hex-cell) design. NMT's stents can be
customized into a variety of sizes, shapes, flexibilities, and radial force
characteristics for use in treating specific indications. The Company utilizes
both the superelastic and thermal shape-memory characteristics of nitinol to
provide for ease of access and delivery of its stents which transform into
their intended shape once placed into the body.
 
NMT's stents have the following characteristics which the Company believes will
offer patients and physicians advantages over many competing stents and
surgical procedures:
 
    . Self-expanding deployment does not necessitate the use of a
      balloon catheter-based delivery system, thereby avoiding
      vessel occlusion during stent placement and simplifying the
      procedure.
 
    . Controlled, sustained radial force, prevents movement of the
      stent after deployment and provides resistance to vessel
      spasm.
 
    . Cannot be permanently deformed by compression or trauma to
      the stented vessel, thereby avoiding accidental reclosure.
 
    .Radial strength, overall rigidity and shape can be varied for
      different medical applications.
 
    . Large expansion ratio (up to 15:1) enables a larger diameter
      NMT stent to be delivered by a small diameter catheter,
      helping to prevent injury at the access site and to adjacent
      vessels and may provide improved access to smaller vessels.
 
    .Minimal length change during deployment aids in precise
       placement.
 
    . Easy mating with graft material to enable use in procedures
      such as AAA repair and peripheral vascular stent grafting.
   
Market Opportunity. From its infancy in 1990, the stent market has grown to
estimated worldwide sales of $500 million in 1995 with continued growth
expected. As shown in the following table, the Company estimates that in 1995
there were approximately 1.7 million procedures for medical conditions that
stents have been designed to address. Although stents are not used currently in
most of these cases, the Company believes that stents may be used as an adjunct
or alternative treatment in many of these procedures.

</TABLE>
 
The estimates in the foregoing table are based on available data concerning
procedures performed in the United States. The Company's estimates outside the
United States are based upon its extrapolation of such data.
 
To date, most stents have been used for the treatment of atherosclerotic plaque
in the coronary arteries. The Company believes that the increase in stent usage
for other procedures and indications has been limited, in part, by the
characteristics of stents currently available. NMT believes that its stents may
offer certain advantages over currently available stents and, in connection
with its collaboration with Boston Scientific, is actively pursuing the
development of its stents in each of the market segments described below. See
"Risk Factors--Limited Commercialization; Uncertainties of Product Development
and Market Acceptance," "--Relationship with Boston Scientific," "--Current
Status" and "--Agreements with Boston Scientific and Bard."
 
Peripheral Vascular. Existing stents for vascular disease include both balloon-
expandable and self-expanding stents. While stent use is well established in
the larger vessels such as the iliac arteries, currently available stents have
limitations in their use in the smaller, more exposed vessels of the leg due to
difficulty of placement, insufficient radial strength and flexibility and a
higher risk of clot formation.
The Company believes that its stents may offer advantages over currently
available stents in flexibility, radial strength and placement. NMT's stents
have precisely engineered radial strength, cannot be permanently deformed after
deployment, and can be delivered using a small diameter catheter.
 
Peripheral Vascular Stent Grafts. For many patients who currently undergo
surgical bypass grafting for the treatment of atherosclerosis in the vessels of
the legs, the length of the blockage makes balloon dilation and traditional
stenting difficult or impractical.
 
The Company believes that its stents may provide for a new minimally invasive
alternative to bypass surgery using long covered stents or multiple stents
joined with graft material (stent grafts) and inserted in the vessel
percutaneously. NMT's stents can be mated easily to graft material, cannot be
deformed by trauma to the stented vessel, can be engineered with precise radial
force to prevent movement and assure hemostasis (absence of blood leakage
around the stent) after deployment. The self-expanding deployment of NMT's
stents may also simplify the delivery mechanics for the physician.
 
Carotid Arteries. While some stenting of the carotid arteries (located near the
surface of the neck) is being done experimentally, the Company believes that
the characteristics of current stents limit their utility in the carotid
arteries. Balloon expandable stents require occluding blood flow to the brain
during deployment. In addition, balloon expandable stents can be permanently
deformed by compression or trauma to the stented vessel.
 
The Company believes its stents will not require occluding blood flow to the
brain during deployment and, unlike currently available balloon expandable
stents, cannot be permanently deformed after deployment, thereby preventing
accidental closure of the vessel. In addition, the Company believes that its
stents can be engineered to exert precise radial force to prevent movement, are
designed to conform well to the vessel shape, have minimal length change during
deployment for highly accurate placement, and can be delivered by a small
diameter catheter.
 
 
                                       24

Abdominal Aortic Aneurysm. The Company believes that the use of a covered stent
or stented graft could provide a minimally invasive alternative to surgery in
the treatment of AAA.
 
The Company believes that its stents may be particularly well suited for AAA
treatment. Specifically, NMT's stents can be mated easily to grafting material
and have sustained radial force to prevent migration and assure hemostasis. In
addition, NMT's stents have a large expansion (up to 15:1) ratio for deployment
of a large diameter stent on a small diameter catheter and are self-expanding
thereby avoiding occlusion of the aorta during deployment and simplifying the
procedure.
 
Esophageal/Biliary. Existing palliative treatment for esophageal cancer
includes painful dilations. Laser ablation is also utilized, but is a treatment
that requires sophisticated equipment and highly-trained physicians, and often
requires expensive repeat procedures. Existing stents for tumor ingrowth of the
bile duct primarily include plastic and self-expanding wire mesh stents.
Plastic stents can become blocked rather quickly because of their narrow
diameter, and the wire mesh stents, due to their mesh design, may not resist
further tumor growth.
 
The Company believes that its stents may have advantages for both of these
indications. NMT's stents have a large expansion ratio for delivery of a large
diameter stent on a small diameter catheter and exert sustained radial force
which may resist recoil from continued tumor growth.
 
Coronary Arteries. Existing stents for coronary disease include balloon-
expandable or self-expanding wire mesh stents.
 
The Company believes that its stents may have advantages over other stents for
use in coronary arteries. NMT's stents are self-expanding to avoid balloon
occlusion of the vessel during placement, may not require post-deployment
ballooning, and exhibit minimal length change during deployment for highly
accurate placement.
 
Relationship with Boston Scientific. In November 1994, NMT licensed to Boston
Scientific, a worldwide leader in sales of minimally invasive medical devices,
exclusive worldwide rights to develop, manufacture, market and distribute the
Company's stent technology. Boston Scientific is the leader in the peripheral
angioplasty market, a leader in the vascular graft market and a leader in the
coronary angioplasty market. Under the terms of this agreement, Boston
Scientific funds, and has control over, product development, manufacturing
scale-up, clinical trials, marketing and distribution worldwide and has the
sole right to use the patents and technical information owned by NMT related to
stents. NMT receives a sales royalty, milestone payments, minimum license fees,
manufacturing cost reduction incentives and reimbursement of development costs.
Boston Scientific has assumed responsibility for conducting the necessary
preclinical and clinical studies, obtaining the regulatory approvals it deems
necessary, and manufacturing and marketing NMT's stents worldwide.
 
Boston Scientific is not prohibited from selling competing stents and has
established a broad-based stent program. In addition to its collaboration with
the Company, Boston Scientific has obtained exclusive worldwide rights to
Medinol, Ltd.'s balloon expandable stent technology and has developed its own
Strecker knitted stent technology and Sabre(TM) self-expanding stent
technology. Boston Scientific launched Medinol's NIR(TM) coronary stent in
Europe in March 1996. In May 1996, Boston Scientific acquired Mintec, Inc., a
privately held company, which develops stent graft technology and has announced
its intention to launch a device for the repair of AAAs in the near future.
 
The Company believes that its relationship with Boston Scientific, a market
leader which has made a significant commitment to developing stent technology,
will facilitate the development and commercialization of the Company's stents.
The Company and Boston Scientific are currently pursuing projects to develop
the Company's stents for a variety of applications. The markets ultimately
targeted for commercial sales will be determined by Boston Scientific pursuant
to the license agreement. See "Risk Factors--Dependence Upon Collaborators" and
"--Agreements with Boston Scientific and Bard."
 
Current Status. European clinical trials for the NMT stent in peripheral
vessels have been initiated by Boston Scientific. Boston Scientific has advised
the Company that it intends to begin marketing a line of the Company's
peripheral vascular stents in Europe during 1996 under the name Symphony and
intends to seek FDA approval of an
 
                                       25
<PAGE>
 
IDE for peripheral vascular applications in the near future. Boston Scientific
has also initiated European trials of the NMT stent for peripheral vascular
stent grafts. Such trials are intended to demonstrate that a stent graft may
provide for a new minimally invasive alternative to bypass surgery using
multiple NMT stents joined with graft material and inserted in the vessel
percutaneously. See "Risk Factors--Limited Commercialization; Uncertainties of
Product Development and Market Acceptance."
 
Boston Scientific is completing a scale-up of its stent manufacturing
capabilities in the United States to enable it to manufacture NMT's stents in
quantities to support clinical trials and initial anticipated commercialization
in certain markets. The Company and Boston Scientific continue to work
collaboratively towards the development of NMT's stents for additional
indications and to achieve manufacturing efficiencies.
 
Competition. Competition in the stent market is intense and is expected to
increase. Most of the stents sold today are balloon expandable and have been
designed primarily for coronary applications. However, the companies listed
below, as well as other companies, may be developing additional stents. Some of
the stents being developed may be more similar to the Company's stents than
those in the market today, although the Company does not know of any competitor
that is developing a stent substantially similar to its product.
 
Johnson & Johnson Interventional Systems Co., Cook Inc., Guidant
Corporation/ACS, Boston Scientific/Medinol, and Arterial Vascular Engineering,
Inc., among others, currently sell stainless steel, balloon expandable stents
in the United States or internationally.
 
The following table lists the Company's major competitors who are currently
selling or, to the Company's knowledge, developing self-expanding stents in the
United States or internationally.

Vena Cava Filters
 
Vena cava filters are used for the prevention of pulmonary embolism (a blood
clot lodged in the vessels supplying blood to the lungs). These emboli (clots),
which often develop initially in the veins of the legs, can break loose and
travel up the vena cava, through the heart and into the blood vessels of the
lungs, causing acute respiratory and circulation problems. Vena cava filters
are intended to trap these clots before they can reach the lungs. Patients at
high risk for pulmonary embolism include post-operative orthopedic and
neurosurgery patients, cancer patients undergoing surgery and chemotherapy and
severe trauma victims. There are 600,000 incidents of pulmonary embolism
diagnosed in the United States each year with 125,000 to 150,000 deaths per
year. While usually treated initially with anticoagulant drugs, vena cava
filters may be used in cases where drug therapy has failed or is
contraindicated. Factors influencing the performance of vena cava filters
include coverage of the vena cava and the pattern of the filtering method.
Additionally, the variety of entry site options and the size of the delivery
system affects ease of deployment.
 
Simon Nitinol Filter. The Company has developed a nitinol vena cava filter
which possesses highly efficient clot filtering characteristics. The Company
has engineered both the superelastic and thermal shape-memory characteristics
of nitinol to provide for ease of delivery of a vena cava filter which can be
easily implanted in the patient by a minimally invasive procedure using the
Company's patented catheter-based delivery systems. The Company's vena
 
                                       26
<PAGE>
 
cava filter transforms into its intended shape once deployed into the body. The
SNF can be implanted from the veins in the leg or neck, and is the only
currently available vena cava filter which can also be implanted from the veins
in the arm.
 
NMT believes the Simon Nitinol Filter offers patients and physicians several
advantages over competing vena cava filters, including the following:
 
    .Sophisticated design facilitates accurate deployment and
      provides for highly efficient clot filtration.
 
    .Smallest diameter catheter-based delivery system results in
      minimal trauma to the access site or to the vessels during
      deployment.
 
    .Largest number of delivery options (leg, neck and arm)
      provides adaptability to individual patient conditions and
      anatomy.
 
    .Device flexibility facilitates easy maneuvering of the device
      through tortuous anatomy during deployment to the filter
      delivery site.
 
Market Opportunity. The worldwide sales for vena cava filters were estimated to
be $53 million in 1995. Worldwide sales for vena cava filters has grown at an
average annual rate of 14% for the past four years. The United States
represents 75% of current worldwide sales. NMT's vena cava filters currently
have an approximately 11% share of vena cava filter sales in the United States.
See "--Competition." The European market is currently small but is expected to
grow as clinical data on the cost effectiveness of vena cava filter use
continues to be developed.
 
Current Status. The Company received FDA 510(k) clearance to market the SNF,
and commenced sales, in April 1990. All 510(k) notifications with respect to
subsequent modifications to the SNF have also been accepted by the FDA. In
November 1995, the Company introduced a simplified, straight line catheter-
based delivery system for its SNF.
 
New Product Development. The Company is currently developing a retrievable vena
cava filter and a superelastic vena cava filter, discussed below.
 
Retrievable Vena Cava Filter. Currently available vena cava filters are
permanent implants which can only be removed surgically. Therefore, patients
who are at risk for pulmonary embolism for a defined period of time (post-
operative recovery, recovery from trauma, etc.) and receive a vena cava filter
have the implant in place for life. There is often a psychological resistance
to implantation of a permanent device. As a result, a vena cava filter is often
not used until a patient at risk has experienced his or her first pulmonary
embolism. However, recent controlled studies conducted by others of the
prophylactic use of currently available permanent vena cava filters in severe
trauma patients have demonstrated a significant reduction in morbidity and
mortality in this category of high-risk patients for pulmonary embolism. The
Company believes that the availability of a retrievable vena cava filter may
result in greater prophylactic use, and may be used in lieu of a permanently
implanted device in certain circumstances.
 
The Company is conducting early design and feasibility work on a retrievable
vena cava filter which can be placed into the body and later removed. Vena cava
filters which remained implanted for six weeks were successfully removed from
sheep in studies conducted by the Company in April 1996. Following additional
laboratory and animal testing, the Company anticipates commencing European
clinical trials during 1997. The Company also anticipates filing an IDE for a
retrievable vena cava filter during 1997 to enable the Company to conduct human
clinical trials in the United States. See "Risk Factors--Limited
Commercialization; Uncertainties of Product Development and Market Acceptance."
 
Superelastic Vena Cava Filter. Presently, all vena cava filters have the
potential for a filter leg to penetrate the wall of the vena cava into
surrounding organs or structures. Although no significant adverse clinical
consequences have resulted from reported protrusions to date associated with
the Simon Nitinol Filter (nor to the Company's knowledge with respect to any
other vena cava filter), the Company believes that a vena cava filter which
utilizes the superelastic
 
                                       27
<PAGE>
 
characteristic of Nitinol to avoid this phenomenon would represent a
technological advance. Furthermore, there can be no assurances that adverse
clinical consequences associated with filter leg penetration will not occur in
the future. See "Risk Factors--Product Liability Risks; Insurance."
 
The Company is conducting research and development related to a superelastic
vena cava filter. The Company's proposed superelastic vena cava filter would
resemble the current SNF but would incorporate structural changes in the legs
of the device enabling each leg of the filter to exert an evenly measured
degree of controlled outward force against the wall of the vessel regardless of
the diameter of the patient's vena cava. The superelastic vena cava filter
would be designed to enable secure placement, while offering constant radial
leg force and reduced potential for penetration of the wall of the vena cava.
The Company believes that this cannot be achieved presently using traditional
device materials. See "Risk Factors--Limited Commercialization; Uncertainties
of Product Development and Market Acceptance."
 
Relationship with Bard. The Company entered into an exclusive distribution
agreement in May 1992 with Bard Radiology for distribution of the SNF in the
United States and certain other countries. Sales and market penetration for the
SNF have increased significantly as a result of this agreement. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." Beginning November 30, 1995, Bard International was granted the
exclusive right to distribute the SNF in most markets outside the United
States. Although there can be no assurance, NMT believes that international
sales and market share growth will increase substantially as a result. The loss
of either distributor would have a material adverse affect on the Company's
business. See "Risk Factors--Dependence Upon Collaborators."
 
Each of the distribution agreements is for a five year term. Bard Radiology may
renew, at its option, its agreement thereafter for periods of five years. The
Company's agreement with Bard International renews automatically for successive
one year periods unless terminated by either party. Both distributors are
obligated to make annual minimum purchases and have agreed not to sell
competing vena cava filters during the term of the respective distribution
agreements. Bard Radiology has also agreed not to compete for an additional two
years after its distribution agreement with the Company has terminated. In
addition, the Company has granted Bard Radiology a right of first offer for any
of NMT's new devices which may be marketed to interventional radiologists and
for which NMT desires to enter into an exclusive distributorship within the
United States. See "--Agreements with Boston Scientific and Bard."
 
Manufacturing. The Company has contracted with Lake Region for the production
of the filter component of the SNF. The Company's agreement with Lake Region
grants Lake Region the right to manufacture at least 75% of the Company's
worldwide requirements of the current filter, for a period of five years until
June 30, 2001. The Company is obligated to order a minimum quantity of the
current filters and pay Lake Region a fixed price per unit. Lake Region has
agreed not to manufacture filters for a third party for a period of two years
after the termination of the agreement. See "Risk Factors--Limited
Manufacturing History; Dependence on Third Parties." The Company currently
purchases the delivery systems for the SNF under purchase orders from third-
party suppliers.
   
Competition. Boston Scientific, among others, currently competes with the
Company in sales of vena cava filters. Boston Scientific introduced the
Greenfield Filter to the market in the mid-1970's and is still the predominant
leader with approximately 70% of current unit sales of vena cava filters in the
United States. Since the introduction of the Simon Nitinol Filter in 1990, NMT
has achieved the second highest level of sales (approximately 11% of current
unit sales, equal to those of B. Braun) in the United States due primarily to
its distribution agreement with Bard Radiology and the introduction of a new
simplified delivery system. Another competitor in this market includes
Cook, Inc.

Septal Repair Devices
 
The Company has acquired exclusive rights to develop and market a patented
septal repair device, the CardioSeal Septal Occluder, which is designed for the
repair of intracardiac shunts commonly known as "holes in the heart."
Intracardiac shunts are common medical problems, occurring primarily in
children, that result in abnormal blood flow through the chambers of the heart.
The most common defects occur in either the atrial ("ASD") or ventricular
("VSD") septum which divide the left and right pumping chambers of the heart.
Patients with these defects may suffer from poorly oxygenated blood and require
increased cardiac effort to adequately supply blood to the body. This may lead
to congestive heart failure and pulmonary hypertension, resulting in severe
incapacity or even death. The current treatment is open heart surgery. Open-
heart surgery involves opening a patient's chest, cutting through the sternum,
connecting the patient to a heart/lung machine and opening the heart to
surgically repair the hole. Such a procedure is costly and generally requires
up to a week of hospitalization and an extensive recovery period. The
CardioSeal Septal Occluder is designed to be a minimally invasive, less costly
alternative to open heart surgery.
 
               The following three diagrams illustrate normal
               cardiac anatomy, a hole in the atrial septum of
               the heart (ASD) and a hole in the ventricular
               septum of the heart (VSD), respectively.

                            [DIAGRAMS APPEAR HERE]

Another common septal defect is the Patent Foramen Ovale ("PFO"), a transient
hole which may open under straining efforts (coughing, defecating, etc.). PFO
has been implicated as a possible cause of embolic strokes, in which small
blood clots escape through the PFO and travel to the brain. Current treatment
for patients who have experienced embolic strokes is lifelong anticoagulation
therapy, which may result in significant side effects and/or patient
noncompliance with the treatment regimen. Recently, some institutions have
begun advocating open heart surgery to close PFO's to prevent additional
strokes. The Company believes that its septal repair device using a minimally-
invasive delivery system may address the needs of the PFO market.
 
               The diagram below shows a cross-section of the
               heart and a transient hole between the left and
               right atriums, know as a PFO.

CardioSeal Septal Occluder. The CardioSeal Septal Occluder is a catheter-
delivered cardiac implant designed to close septal defects. The device consists
of eight wire spring arms covered with two pieces of knitted polyester fabric
which form two opposed disk-like occluders each having an umbrella shape. The
framework is made of MP35N, a material chosen because of its superior
characteristics as an implant material (biocompatibility and corrosion and
fatigue resistance). Knitted polyester was chosen because of its extensive use
in the cardiovascular system and its ability to promote normal tissue in-
growth. At the center of the occluders is an inter-connection point which
allows the product to be placed within the septal defect so that one umbrella
is opened on each side of the defect. The product is designed to be
manufactured in five diameter sizes ranging from 17mm to 40mm.
 
The CardioSeal Septal Occluder is delivered to the site of the defect through a
puncture of the femoral vein in the leg. The device is loaded into a delivery
catheter and moved toward the defect site (top left diagram). At the defect
site, the CardioSeal Septal Occluder is deployed through the defect (top center
diagram) and the first umbrella is opened (top right diagram). The delivery
system is then retracted through the hole so that the first umbrella comes into
contact with the septal wall (bottom left diagram). The delivery system is then
retracted further allowing the second umbrella to open and seal the defect from
both sides (bottom center diagram). Once the position of the CardioSeal Septal
Occluder is confirmed, the physician detaches the delivery system and removes
it from the patient (bottom right diagram).
 
 
 
                           [DIAGRAMS APPEARS HERE] 
 
 

   
An earlier version of the septal repair device, named the Clamshell, was
developed by Bard in collaboration with Children's Hospital of Boston. Between
1989 and 1991 Bard sponsored clinical trials of the Clamshell in over 700
patients with a variety of cardiac conditions. In 1991, Bard discovered
fractures of the stainless steel framework in certain of the devices implanted
during such clinical trials and, following such discovery, suspended its
clinical trials. However, Bard subsequently submitted, and the FDA approved, a
revised IDE to permit the continued use of the Clamshell for patients with
limited therapeutic alternatives and at high risk for surgical repair of their
condition. The Company is not aware of any significant adverse clinical
consequences, such as death or life-threatening injury necessitating emergency
surgery, resulting from the observed fractures. Redesign efforts were initiated
in collaboration with Dr. James Lock, Chairman of the Cardiology Department at
Children's Hospital of Boston. Extensive engineering redesign and testing,
including the use of MP35N for the framework, resulted in significant
improvements in both the fatigue and corrosion resistance of the device. See
"Risk Factors--Uncertainties of Successful Redesign of the Septal Repair
Device" and "Risk Factors--Product Liability Risks; Insurance."     
 
In 1995, Bard donated the technology and associated assets to Children's
Hospital of Boston which subsequently licensed the technology to InnerVentions.
The Company acquired the rights to develop and commercialize the current septal
repair device in February 1996. In connection with the acquisition, the Company
acquired all of the existing development, manufacturing and testing equipment,
patent licenses, know-how and documentation necessary to manufacture septal
repair devices which had been originally developed by Bard. NMT has hired
certain key personnel who worked on this project at Bard. See "Certain
Transactions."
 
Market Opportunity. The Company believes the CardioSeal Septal Occluder may be
suitable for approximately 55,000 patient implants annually for congenital
heart defects and approximately 145,000 adult patients annually with
 
                                       30
<PAGE>
 
PFOs. Such estimates are based on industry reports of the total numbers of
patients diagnosed with such conditions and the Company's own analysis of the
portions of such populations for whom its device may be suitable. See "Risk
Factors--Limited Commercialization; Uncertainties of Product Development and
Market Acceptance."
 
Current Status. The Company believes that based on clinical usage of the septal
repair device since 1989, clinical utility has been demonstrated. Children's
Hospital of Boston is currently conducting clinical trials of the redesigned
Clamshell device under an IDE granted by the FDA in the second quarter of 1996
to allow for use of the devices in patients with a variety of cardiac
conditions and at high risk for surgery. The devices being tested by Children's
Hospital of Boston were provided by Bard and were not included in the assets
acquired by the Company. The CardioSeal Septal Occluder will be manufactured
based on the same design specifications as the redesigned Clamshell devices
currently being tested by Children's Hospital of Boston.
 
The Company has tested the CardioSeal Septal Occluder with an extensive series
of pre-clinical tests. Such pre-clinical testing culminated with an accelerated
in vitro life test of 630 million cycles (which equates to 10 years at 120
heartbeats per minute). During such testing, no fractures occurred in the
CardioSeal Septal Occluder even though the stress levels were set to simulate
significantly greater levels of stress observed clinically with the original
Clamshell device. The Company believes that the current CardioSeal Septal
Occluder is now ready to enter clinical trials and intends to commence clinical
trials for the CardioSeal Septal Occluder in Europe in late 1996. In the United
States, the FDA classifies the septal repair device as a Class III medical
device, which requires receipt of pre-market approval prior to marketing. In
August 1996, the Company received conditional approval of its IDE to conduct a
multi-center, pivotal clinical trial in the United States for ASDs. The
Company's approval is conditioned on minor modifications to the investigational
plan recommended by the FDA and accepted by the Company, and the submission of
additional data to the FDA within 45 days, which the Company is preparing. The
Company anticipates initiating its United States clinical trials for ASD in the
fourth quarter of 1996 pending product availability. See "Risk Factors--
Government Regulation; Product Approvals Uncertain."
 
Clinical protocol submissions have been made in Canada and Europe to commence
ASD clinical trials. The study protocol will be substantially the same as that
used in the United States. The Company anticipates commencement of these
clinical trials in late 1996 and will pursue clinical studies for the PFO
indication following the successful completion of its ASD trials. There can be
no assurances, however, that the Company's proposed clinical trials will be
successfully completed or that the Company will be able to achieve the
foregoing product development schedule. See "Risk Factors--Government
Regulation; Product Approvals Uncertain."
 
New Product Development. The Company is currently evaluating design
enhancements to the CardioSeal Septal Occluder as well as alternative designs
for the device. The Company is considering the use of nitinol for the device to
further reduce the size of the delivery system, further simplify the deployment
procedure and potentially broaden the range of therapeutic indications.
 
Marketing and Sales Strategy. The Company intends to develop its own sales
force to market the CardioSeal Septal Occluder. There are approximately 150 to
200 pediatric interventional cardiologists in the United States who could
potentially implant the device. These specialists practice at an estimated 75
to 100 institutions that provide advanced cardiac care to children. It is
estimated that a similar number of centers would be targeted internationally.
Therefore, the Company believes that the size and scope of the target audience
is manageable with a small, specialized sales and marketing team. The Company's
marketing strategy will require a specific physician training program prior to
selling products into any center. See "Risk Factors-- Limited Manufacturing
History; Dependence on Third Party Manufacturers."
 
Manufacturing. The Company has signed a lease for, and is in the process of
renovating, an approximately 27,000 square foot facility in Boston,
Massachusetts. A fully integrated GMP and ISO 9000 manufacturing facility will
be included in this space so that the manufacture of the CardioSeal Septal
Occluder can be appropriately controlled. Integral to the facility will be a
Class 10,000 clean room for the final manufacture of the device. See "Risk
Factors--Limited Manufacturing History; Dependence on Third Party
Manufacturers."
 
Competition. The Company believes that only three companies, Microvena
Corporation, Dr. Osypka GmbH, and Pediatric Cardiology Custom Medical Devices
are actively developing competitive devices and that none of these companies
currently has a product on the market.
 
PATENTS AND PROPRIETARY TECHNOLOGY
 
The Company seeks to protect its technology through the use of patents and
trade secrets. The Company is the owner or licensee of eight issued United
States patents, and corresponding foreign patents, relating to its stents, the
SNF, the
 
                                       31
<PAGE>
 
septal repair device and nitinol radiopaque markers. The Company has received a
notice of allowance from the United States Patent and Trademark Office on a
ninth United States patent application. In addition, the Company has pending
applications for additional patents in the United States and abroad. The
Company's owned United States and foreign patents and patent applications cover
its stents, methods of manufacturing its stents, methods and devices for
inserting its stents, its SNF and devices for inserting its SNF. The expiration
dates of the Company's patents relating to its stents range from 2012 to 2013.
The patent for its vena cava filters expires in 2001 and the patent for its
radiopaque markers expires in 2014. In addition, the Company is the exclusive
licensee under certain patents relating to the CardioSeal Septal Occluder and
methods for repairing cardiac and vascular defects. The Company also holds
licenses to certain technology used in the SNF and in nitinol septal repair
devices. See "--Licensed Technology; Royalty Obligations."
 
There can be no assurance that the Company's pending patent applications in the
United States and abroad will be granted. No assurance can be given that
patents issued to or licensed by or to the Company will not be challenged,
invalidated or circumvented, or that the rights granted thereunder will provide
any competitive advantage. The Company could incur substantial costs in
defending any patent infringement suit or in asserting any patent rights,
including those granted by third parties. Any adverse outcome could subject the
Company to significant liabilities to third parties, require disputed rights to
be licensed from third parties, or require the Company to cease selling its
devices.
 
The Company also relies on trade secrets and technical know-how in the
development and manufacture of its devices, which it seeks to protect, in part,
through confidentiality agreements with its employees, consultants and other
parties. The Company's agreements with its employees and consultants generally
require such individuals to assign to the Company any inventions conceived or
reduced to practice by them while employed or retained by the Company. There
can be no assurance, however, that these agreements will provide meaningful
protection or adequate remedies for the Company in the event of unauthorized
use, transfer or disclosure of such information or inventions.
 
The employment agreements between the Company and Mr. Kleshinski, Vice
President of Research and Development, and Dr. Harry, Vice President of
Research Engineering, while requiring that their inventions be assigned to the
Company, provide that the Company is obligated to pay certain royalties to
Messrs. Kleshinski and Harry based on sales or licenses of products where
either Mr. Kleshinski or Dr. Harry, as the case may be, was the sole or joint
inventor.
 
The Company has seven trademarks, two of which are registered in the United
States Patent and Trademark Office.
 
LICENSED TECHNOLOGY; ROYALTY OBLIGATIONS
 
In connection with its septal repair device, the Company has obtained an
exclusive worldwide license from Children's Medical Center Corporation under
United States patents entitled "Occluder and Method for Repair of Cardiac and
Vascular Defects" and "Occluder for Repair of Cardiac and Vascular Defects" and
the respective corresponding foreign patents, patent applications and
associated know-how. The license agreement provides for royalty payments of
five percent based on net sales of the Company's CardioSeal Septal Occluder
until the end of the term of the patents or termination of the agreement. The
patents expire in September 2012 and June 2012, respectively. Pursuant to the
license agreement, the Company is required to achieve certain milestones in
exploiting the patent rights. The Company has achieved all required milestones
to date. If the Company fails to achieve the milestones, Children's Medical
Center Corporation may terminate the license agreement. The Company also has a
royalty-free, worldwide sublicense under the United States patent entitled
"System for the Percutaneous Transluminal Front-End Loading Delivery and
Retrieval of a Prosthetic Occluder" and its corresponding foreign patents and
associated know-how. The sublicense is exclusive in the field of the repair of
atrial septal defects and nonexclusive in certain other fields. The Company has
also obtained an exclusive worldwide license from Lloyd A. Marks, M.D. under
the United States patent entitled "Aperture Occlusion Device". The license
agreement with Dr. Marks provides for royalty payments based on net sales of
nitinol septal repair devices which are covered by the patent until the end of
term of the patent in 2011. Certain minimum royalty payments must be paid
regardless of net sales. Dr. Marks was also issued warrants to purchase 5,263
shares of Common Stock, which warrants are accompanied by certain "piggy-back"
registration rights. See "Description of Capital Stock--Registration Rights."
 
In connection with the Simon Nitinol Filter, the Company entered into a
Technology Purchase Agreement dated April 14, 1987 with Morris Simon, M.D., the
Company's Scientific Director and co-founder. Pursuant to the agreement, Dr.
 
                                       32
<PAGE>
 
Simon assigned all the technology relating to the SNF to the Company in
exchange for certain royalty payments based on net sales of technology invented
by Dr. Simon relating to the SNF, to continue perpetually unless the agreement
is sooner terminated. Dr. Simon agreed not to compete with the Company in the
vena cava filter market during the term of the agreement. In connection with
the agreement, Beth Israel Hospital Association granted the Company an
exclusive worldwide license under U.S. patent entitled "Blood Clot Filter". In
consideration for the license, Dr. Simon assigned a percentage of his royalty
payments from the Company to Beth Israel Hospital Association.
 
Pursuant to their respective employment agreements, the Company has agreed to
pay royalties of one to five percent to Messrs. Kleshinski and Harry based on
sales or licenses of products where either Mr. Kleshinski or Dr. Harry, as the
case may be, was the sole or joint inventor. See Note 8 of Notes to the
Consolidated Financial Statements. The Company is not obligated to pay
royalties to Mr. Kleshinski with respect to the Company's stents or vena cava
filters or to Dr. Harry with respect to the Company's devices which were being
sold prior to January 1994 unless Dr. Harry's inventions result in an increased
sales price to the Company. See "Management--Employment Agreements."
 
AGREEMENTS WITH BOSTON SCIENTIFIC AND BARD
 
Boston Scientific
 
In November 1994, NMT entered into an agreement with Boston Scientific,
pertaining to its stent technology. Under the terms of the agreement, NMT
granted to Boston Scientific exclusive worldwide rights to develop,
manufacture, market and distribute products incorporating NMT's stent
technology. Boston Scientific has the right to market and advertise products
based on the Company's stent technology exclusively under its own name and the
Company has no right to any trademarks or tradenames developed by Boston
Scientific. Boston Scientific has exclusive control over, and is responsible
for, funding product development, manufacturing scale-up, clinical trials,
marketing and distribution worldwide. The agreement obligates Boston Scientific
to use diligent efforts in a commercially reasonable manner to develop,
manufacture and market products using NMT's stent technology; however, there
can be no assurance that Boston Scientific will develop the Company's stents
for any particular application. In addition, Boston Scientific is not
prohibited from developing or selling competing stents. See "Risk Factors--
Dependence Upon Collaborators."
 
Boston Scientific is obligated to pay NMT a percentage of revenue from the sale
of products using NMT's stent technology. If the fees payable are less than
certain minimum levels, Boston Scientific must pay the difference or NMT can
elect to make the license non-exclusive. The license fees may be reduced in the
event a competing stent with a similar design, as defined in the agreement,
acquires a 10% or greater sales share with respect to any particular
application. Boston Scientific is also obligated to make payments upon the
occurrence of certain developmental events and the achievement of certain
manufacturing cost reductions, and reimburse certain development costs.
 
The term of the agreement is for the longer of 20 years from market launch or
the date on which the last NMT patent relating to stents expires. Boston
Scientific also has the perpetual non-exclusive and royalty-free right to
manufacture, use and sell all products as to which it has previously paid
licensing fees and on products for which all applicable patents have expired or
have been held invalid. Such additional rights granted to Boston Scientific
survive termination of the agreement.
 
Bard
 
The Company has entered into strategic distribution agreements with Bard
Radiology (as amended, the "Bard Radiology Agreement") and Bard International
(the "Bard International Agreement") to distribute the SNF in the United States
and certain other countries.
 
The Bard Radiology Agreement, signed in May 1992 and amended in February 1993
and October 1995, grants Bard Radiology the exclusive right to distribute the
Simon Nitinol Filter, and any changes, improvements or modifications thereto,
in the United States and certain other countries for a five year term renewable
by Bard Radiology for additional five year terms thereafter. The Company also
granted Bard Radiology a right of first offer to obtain exclusive distribution
rights in the United States for any new devices developed by the Company that
may be marketed to interventional radiologists and for which NMT desires to
enter into an exclusive distributorship within the United States. The Company
sells the SNF to Bard Radiology at determined prices and Bard Radiology is
required to purchase certain minimums to maintain its exclusivity. Pursuant to
the Bard Radiology Agreement, Bard Radiology is obligated to provide the
Company with quarterly purchase orders in substantial conformity with its
purchase forecasts
 
                                       33
<PAGE>
 
submitted to the Company. Bard Radiology has further agreed not to compete with
the Company in the vena cava filter market during the term of the agreement and
for two years after termination. The Company has agreed not to make or sell any
competing device as long as Bard maintains its exclusivity under the agreement.
 
The Bard International Agreement, signed in November 1995, grants Bard
International the exclusive right to distribute the Simon Nitinol Filter, and
any changes, improvements or modifications thereto, worldwide (excluding the
United States and certain other countries) for a five year term which is
automatically renewed for successive one year periods unless terminated by
either party. The Company sells the SNF to Bard International at determined
prices and Bard International is required to make certain minimum purchases
which, if not met, could result in termination of the agreement by the Company.
Pursuant to the Bard International Agreement, Bard International is obligated
to provide the Company with quarterly purchase orders in substantial conformity
with its forecasts submitted to the Company. Bard International has further
agreed not to compete with the Company in the vena cava filter market during
the term of the Bard International Agreement.
 
GOVERNMENT REGULATION
 
The manufacture and sale of medical devices intended for commercial
distribution are subject to extensive governmental regulations in the United
States. Medical devices are regulated in the United States by the FDA under the
FDC Act and generally require pre-market clearance or pre-market approval prior
to commercial distribution. In addition, certain material changes or
modifications to medical devices also are subject to FDA review and clearance
or approval. Pursuant to the FDC Act, the FDA regulates the research, testing,
manufacture, safety, labeling, storage, record keeping, advertising,
distribution and production of medical devices in the United States.
Noncompliance with applicable requirements can result in failure of the
government to grant pre-market clearance or approval for devices, withdrawal of
approvals, total or partial suspension of production, fines, injunctions, civil
penalties, recall or seizure of products, and criminal prosecution. The FDA
also has the authority to request repair, replacement or refund of the cost of
any device manufactured or distributed by the Company.
 
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. Class I devices are subject to general
controls and Class II devices are subject to general and to special controls
(e.g., performance standards, postmarket 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 devices, or new devices which
have not been found to be substantially equivalent to legally marketed
devices), and 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 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 applications.
 
If human clinical trials of a device are required and 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 results of
animal and, possibly, mechanical testing. If the IDE application is approved by
the FDA, human clinical trials may begin at a specific number of
investigational sites with a maximum number of patients, as approved by the
agency. Sponsors of clinical trials are permitted to sell those devices
distributed in the course of the study provided such costs do not exceed
recovery of the costs of manufacture, research, development and handling. The
clinical trials must be conducted under the auspices of an independent
institutional review board ("IRB") established pursuant to FDA regulations. If
one or more IRBs determine that a clinical trial involves a "nonsignificant
risk" device, the sponsor of the study is not required to obtain FDA approval
of an IDE application before beginning the study. However, prior IRB approval
of the study is required and the study must be conducted in compliance with the
applicable FDA regulations, including, but not limited to, FDA's regulations
regarding the protection of human subjects.
 
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 pre-
market notification ("510(k) notification") submission or 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
 
                                       34
<PAGE>
 
for PMAs, the manufacturer or distributor may seek clearance from the FDA to
market the device by filing a 510(k) notification. The 510(k) notification may
need to be supported by appropriate data establishing the claim of substantial
equivalence to the satisfaction of the FDA. The FDA recently has been requiring
a more 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
order is issued by the FDA. At this time, the FDA typically responds to the
submission of a 510(k) notification within 90 to 200 days, but it may take
longer. An FDA order 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 could delay market
introduction of the product that is the subject of the 510(k) notification. For
any devices that are cleared through the 510(k) process, modifications or
enhancements that could significantly affect safety or effectiveness, or
constitute a major change in the intended use of the device, will require new
510(k) submissions.
 
If a manufacturer or distributor of medical devices cannot establish that a
proposed device is substantially equivalent to a legally marketed device, the
manufacturer or distributor must seek pre-market approval of the proposed
device through submission of a PMA application. A PMA application must be
supported by extensive data, including preclinical and clinical trial data, as
well as extensive literature to prove the safety and effectiveness of the
device. Following receipt of a PMA application, if the FDA determines that the
application is sufficiently complete to permit a substantive review, the agency
will "file" the application. Under the FDC Act, the FDA has 180 days to review
a filed PMA application, although the review of an application more often
occurs over a protracted time period, and generally takes approximately two
years or more from the filing date to complete.
 
The PMA approval process is expensive, uncertain and lengthy. A number of
devices for which pre-market approval has been sought have never been approved
for marketing. The review time is often significantly extended by the FDA,
which may require more information or clarification of information already
provided in the submission. During the review period, an advisory committee
likely will be convened by the FDA to review and evaluate the application and
provide recommendations to the agency as to whether the device should be
approved. In addition, the FDA will inspect the manufacturing facility to
ensure compliance with the GMP regulations for medical devices prior to
approval of the PMA application. If granted, the approval may include
significant limitations on the indicated uses for which a product may be
marketed. The FDA's regulations require agency approval of a PMA supplement for
certain changes if they affect the safety and effectiveness of the device,
including, but not limited to, new indications for use; labeling changes; the
use of a different facility to manufacture, process, or package the device.
 
Certain Class III devices that were on the market before May 28, 1976
("preamendments Class III devices"), and devices that are determined to be
substantially equivalent to them, can be brought to market through the 510(k)
process until the FDA, by regulation, calls for PMA applications for the
devices. Generally, the FDA will not grant 510(k) clearance for such devices
unless the facilities at which they are manufactured successfully undergo an
FDA pre-approval GMP inspection. In addition, the FDC Act requires the FDA
either to down-classify preamendments Class III devices to Class I or Class II,
or to publish a classification regulation retaining the devices in Class III.
Manufacturers of preamendments Class III devices that the FDA retains in Class
III must have PMA applications accepted by the FDA for filing within 90 days
after the publication of a final regulation in which the FDA calls for PMAs. If
the FDA calls for a PMA for a preamendments Class III device, a PMA must be
submitted for the device even if the device has already received 510(k) pre-
market clearance; however, if the FDA down-classifies a preamendments Class III
device to Class I or Class II, a PMA application is not required. The FDA's
reclassification determinations are to be based on safety and effectiveness
information that manufacturers of certain preamendments Class III devices are
required to submit to the FDA as set forth in two FDA orders published in
August 1995.
 
The Company's first product, the SNF, underwent significant clinical
investigation under an IDE and received 510(k) clearance in 1990. Subsequent
improvements and modifications to the SNF have also received 510(k) clearance
from the FDA. The Company currently is preparing a 510(k) submission seeking
clearance for additional modifications. There can be no assurances that such
future modifications of the device will obtain clearance. The 510(k) clearances
for the SNF were based on substantial equivalence of the device to other
cardiovascular intravascular filters, which are
 
                                       35
<PAGE>
 
preamendments Class III devices. The FDA has characterized cardiovascular
intravascular filters as not likely candidates for down-classification under
the reclassification provisions of the FDC Act pertaining to preamendments
Class III devices. Thus, it is likely that the FDA will call for PMAs for
cardiovascular intravascular filters and that the Company will be required to
have a PMA for the SNF accepted for filing by the FDA within 90 days after the
date that the FDA calls for PMAs. There can be no assurance that the Company
will be able to file a PMA within the prescribed time period or that any data
and information submitted in a PMA will be adequate to support approval of the
device. The Company believes it would be able to file a PMA within a 90 day
time frame utilizing its existing clinical data. If the FDA were to require the
Company to conduct a new clinical study to support the safety and efficacy of
the SNF, the preparation of the PMA would take substantially longer than 90
days. Failure of the Company to submit a PMA and have it accepted for filing by
the FDA within the required timeframe could result in the Company being
required to cease commercial distribution of the SNF. Upon timely filing of a
PMA, the Company believes, based on FDA's announced position as to certain
other preamendments class III medical devices, that the FDA would permit
continued commercial distribution of the SNF during the time necessary to
review the PMA. There can be no assurance, however, that FDA would permit
continued commercial distribution of the SNF pending FDA's review of a PMA for
that device nor can there be any assurance given that the FDA would approve a
PMA submitted for the SNF. Any denial by the FDA of a PMA for the SNF would
result in the Company being required to cease commercial distribution of the
SNF. Any requirement by the agency that the Company cease commercial
distribution of the SNF would have a material adverse effect on the Company's
business, financial condition and results of operations. On July 22, 1996, the
Company submitted safety and effectiveness data to the FDA in accordance with
one of the August 1995 FDA orders addressing the classification of
preamendments Class III devices. The FDA will use this data, along with data
furnished by manufacturers of similar devices, in determining the final
classification of the SNF.
 
Boston Scientific is responsible for applying for registrations and regulatory
approvals it deems necessary for NMT's stents. It is believed that each of the
vascular indications for the stent (coronary arteries, carotid arteries,
peripheral vascular, AAA and peripheral vascular stent grafts) will require
separate PMA applications prior to commercialization in the United States.
Boston Scientific has commenced clinical trials in Europe of NMT's stents for
peripheral vascular and peripheral vascular stent grafts applications.
Commencing clinical trials in Europe is a strategy, now commonly used in the
industry, which allows significant information to be gained and may enhance the
ability to develop a United States based protocol of study.
 
The Company believes, based on competitive product filings, that the non-
vascular stent indications will qualify for the 510(k) notification. The
filings for esophageal and biliary indications will also be the responsibility
of Boston Scientific. There can be no assurance that the FDA will agree that
the non-vascular stent indications may be cleared through the 510(k) process
or, if a 510(k) notification is submitted, that the non-vascular stent will be
deemed substantially equivalent to a legally marketed predicate device. In
addition, there can be no assurance that Boston Scientific will submit
regulatory filings for any particular indications for the stents, or that
Boston Scientific will submit regulatory filings in every country in which the
stents could be marketed. See "Risk Factors--Government Regulation; Product
Approvals Uncertain."
 
The septal repair device will also be subject to the PMA process in the United
States. NMT submitted an application for an IDE to the FDA in May 1996.
Submission of an IDE does not give assurance that the FDA will approve the IDE
and, if it is approved, there can be no assurance that the FDA will determine
that the data derived from these studies support the safety and efficacy of the
device or warrant the continuation of clinical studies.
 
There can be no assurance that the Company will be able to obtain necessary
regulatory approvals or clearances for its products on a timely basis or at
all, and delays in receipt of or failure to receive such approvals or
clearances, the loss of previously received approvals or clearances,
limitations on intended use imposed as a condition of such approvals or
clearances, or failure to comply with existing or future regulatory
requirements could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
Currently, the Company is dependent on third parties to manufacture its
products for use in clinical trials and commercial distribution. These third
parties are required to register with the FDA as medical device manufacturers.
 
                                       36
<PAGE>
 
The third party manufacturers are inspected by the FDA for compliance with the
GMP and other applicable regulations. In addition, the third party
manufacturers will be specifically inspected by the FDA before the agency will
approve a PMA application for the Company's products. There can be no assurance
that the third party manufacturers on which the Company depends for the
manufacture of its products will be able to come into compliance with the GMP
regulations at the time of the preapproval inspection or to maintain such
compliance.
 
The Company currently intends to manufacture its septal repair device. The
Company's manufacturing facilities will be required to be registered with the
FDA and will be subject to the GMP regulations. FDA approval will be required
before the Company could begin commercial distribution of medical devices from
its own manufacturing facilities.
 
Any products manufactured or distributed by the Company are subject to
continuing regulation by the FDA including record keeping requirements,
reporting of adverse experience with the use of the device, post-market
surveillance, post-market registry and other actions deemed necessary by the
FDA.
 
The Company is required to provide information to the FDA on deaths or serious
injuries alleged to have been associated with the use of its medical devices,
as well as product malfunctions that would likely cause or contribute to death
or serious injury if the malfunction were to recur in a similar device marketed
by the manufacturer. In addition, the FDA prohibits an approved device from
being marketed or promoted for unapproved uses. If the FDA believes that a
company is not in compliance with the law, it can initiate proceedings to
detain or seize products, issue a recall, enjoin future violations and assess
civil and criminal penalties against the Company, its officers and its
employees. Failure to comply with applicable regulatory requirements could have
a material adverse effect on the Company's business, financial condition and
results of operation.
 
The advertising of most FDA-regulated products is subject to both FDA and
Federal Trade Commission jurisdiction. The Company also is subject to
regulation by the Occupational Safety and Health Administration and by other
governmental entities.
 
Sales of medical device products outside the United States are subject to
foreign regulatory requirements that vary widely from country to country. The
time required to obtain approvals required by foreign countries may be longer
or shorter than that required for FDA approval, and requirements for licensing
may differ from FDA requirements. Failure to comply with foreign regulatory
requirements also 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. There is currently no universally
accepted definition of a medical device in Europe and there is no common
approach to medical device regulation among the various countries. There are
several different regulatory regimes operating within the different European
countries. Regulatory requirements for medical devices range from no
regulations in some countries to rigorous regulations approaching the
requirements of the FDA's regulations for Class III medical devices. Several
countries require that device safety be demonstrated prior to approval for
commercialization. The regulatory environment in certain European countries is
expected to undergo major changes as a result of the creation of medical device
directives by the European Union.
 
Regulations regarding the manufacture and sale of the Company's products are
subject to change. The Company cannot predict what impact, if any, such changes
might have on its business, financial condition or results of operations.
 
The Company plans to implement policies and procedures intended to allow the
Company to receive ISO 9000 certification. ISO 9000 certification is based on
adherence to established standards in the areas of quality assurance and
manufacturing process control. This certification is a significant European
Union sales requirement that will permit the Company or its collaborators to
affix the prescribed "CE" mark to its products. The European Union has
promulgated rules which require that medical products receive a CE mark by mid-
1998 in order to commercially market and sell medical products in the countries
of the European Economic Area. Failure to receive CE mark certification will
prohibit the Company from selling its products in Europe. There can be no
assurance that the Company will be successful in meeting their certification
requirements.

THIRD PARTY REIMBURSEMENT
 
Health care providers, such as hospitals and physicians, that purchase medical
devices such as stents, generally rely on third party payers, principally
Medicare, Medicaid and private health insurance plans, to reimburse all or part
of the costs and fees associated with the Company's devices. Major third party
payers reimburse inpatient medical treatment, including all operating costs and
all furnished items or services, including devices such as the Company's, at a
prospectively fixed rate based on the DRG that covers such treatment as
established by the federal Health Care Financing Administration. For
interventional procedures, the fixed rate of reimbursement is based on the
procedure or procedures performed and is unrelated to the specific devices used
in that procedure. The amount of profit relating to the procedure may be
reduced by the use of the Company's devices. If a procedure is not covered by a
DRG, certain third party payers may deny reimbursement. Alternatively, a DRG
may be assigned that does not reflect the costs associated with the use of the
Company's devices, resulting in underreimbursement. If, for any reason, the
Company's products were not to be reimbursed by third party payers, the
Company's ability to sell its products may be materially adversely affected.
Mounting concerns about rising health care costs may cause more restrictive
coverage and reimbursement policies to be implemented in the future. Several
states and the federal government are investigating a variety of alternatives
to reform the health care delivery system and further reduce and control health
care spending. These reform efforts include proposals to limit spending on
health care items and services, limit coverage for new technology and limit or
control directly the price health care providers and drug and device
manufacturers may charge for their services and products. The Company believes
that domestic health care providers currently are reimbursed for the cost of
purchasing the Company's SNF. In the international market, reimbursement by
private third party medical insurance providers, including governmental
insurers and providers, varies from country to country. In certain countries,
the Company's ability to achieve significant market penetration may depend upon
the availability of third party governmental reimbursement. The Company's
independent distributors, and the health care providers to whom such
distributors sell, obtain any necessary reimbursement approvals. There can be
no assurance as to either United States or foreign markets that third party
reimbursement and coverage will be available and adequate, that current
reimbursement amounts will not be decreased in the future or that future
legislation, regulation or reimbursement policies of third party payers will
not occur. See "Risk Factors--Uncertain Availability of Third Party
Reimbursement; Possible Health Care Reforms."
 
EMPLOYEES
 
As of July 31, 1996, NMT employed 31 full-time and three part-time employees.
Further staff will be added at the completion of the Offering as required by
the demands of the planned manufacturing scale-up for the septal repair device
and other development programs. No employees are covered by collective
bargaining agreements, and the Company believes it maintains good relations
with its employees.
 
FACILITIES
 
The Company currently occupies approximately 7,500 square feet of laboratory,
pilot manufacturing and office space in Boston. The Company has entered into a
lease for a new manufacturing, laboratory and administrative facility in Boston
comprising approximately 27,000 square feet which it expects to occupy
commencing in the third quarter of 1996.
 
LEGAL PROCEEDINGS
 
The Company has no material pending legal proceedings.
 
PRODUCT LIABILITY AND INSURANCE
 
The Company's business involves the risk of product liability claims. The
Company has not experienced any product liability claims to date. Although the
Company maintains product liability insurance with coverage limits of $5
million per occurrence and an annual aggregate maximum of $5 million, there can
be no assurance that product liability claims will not exceed such insurance
coverage limits, which could have a material adverse effect on the Company's
business, financial condition and results of operations, or that such insurance
will be available on commercially reasonably terms or at all. See "Risk
Factors--Product Liability Risks; Insurance."

or its stockholders, (ii) acts or omissions not in good faith or which involve
intentional

or unlawful stock repurchases or redemptions or (iv) any transaction form which
the director derived an improper personal benefit. Such limitation of liability
does not apply to liabilities arising under the federal securities laws and

relief or rescission. The Company's bylaws provide that the Company shall
indemnify its directors and executive officers and may indemnify its other
officers and employees and other agents to the fullest extent permitted by law.

first year, $175,000 the second year and $185,000 the third year. Mr.
Chazanovitz is also eligible to receive bonus payments upon the achievement by
the Company of certain specified goals. In connection with his employment, Mr.
Chazanovitz received (i) non-qualified stock options to purchase 92,105 shares
of the Company's Common Stock at an exercise price of $2.15 per share, which
vest at a rate of 2.77% per month and (ii) options to purchase an aggregate of
up to 26,315 shares of the Company's Common Stock at an exercise price of $2.15
per share subject to vesting in the amounts and upon the earlier of (x) the

(y) December 31, 2000. See "--Options Granted Outside of the Plans." The
options are exercisable for a period of ten years after the vesting thereof and
become immediately exercisable in the event of a change of control of the
Company. If Mr. Chazanovitz' employment is terminated due to his death or
disability, the portion of the options due to become exercisable on the first
day of the month coincident with or next following the date of termination,
prorated for the number of days he was employed during the month, shall become
exercisable and all other unexercisable options shall expire. Mr. Chazanovitz
will forfeit all unexercisable options if the Company terminates his employment
with or without cause. If the Company terminates Mr. Chazanovitz' employment
without cause, the Company will be obligated to continue to pay his annual
salary for a period of six months from termination. Mr. Chazanovitz has agreed
not to compete with the Company for a period of one year after he ceases to be
employed by the Company.
 
Effective May 1996, Theodore I. Pincus became Executive Vice President and
Chief Financial Officer pursuant to a three-year employment agreement. Pursuant
to his employment agreement, Mr. Pincus receives a salary of $160,000 the first
year, $175,000 the second year and $185,000 the third year. In addition, Mr.
Pincus receives living expenses of $35,000 the first year and $20,000 the
second year, in lieu of receiving the Company's relocation benefits package.
Mr. Pincus is also eligible to receive bonus payments upon the achievement by
the Company of certain specified goals. In connection with his employment, Mr.
Pincus received non-qualified stock options to purchase 39,473 shares of Common
Stock of the Company at an exercise price of $2.15 per share. The options vest
in equal monthly installments over three years. See "--Options Granted Outside
of the Plans." The options are exercisable for a period of ten years after the
vesting thereof and become immediately exercisable in the event of a change of
control of the Company. If Mr. Pincus' employment is terminated due to his
death or disability, the portion of the options due to become exercisable on
the first day of the month coincident with or next following the date of
termination, prorated for the number of days he was employed during that month,
shall become exercisable and all other unexercisable options shall expire. Mr.
Pincus will forfeit all unexercisable options if the Company terminates his
employment either with or without cause. If the Company terminates Mr. Pincus'
employment without cause, the Company will be
 
                                       44
<PAGE>
 
obligated to continue to pay his annual salary for a period of six months after
termination. The Company loaned Mr. Pincus $65,000, which loan will be forgiven
over the next three years; provided, however, that (i) if Mr. Pincus is
terminated for cause (as defined in his employment agreement) the then-
outstanding loan together with interest at prime plus one percent shall become
immediately due and payable, or (ii) if Mr. Pincus is terminated for any other
reason, the then-outstanding loan together with interest at prime plus one
percent shall be payable monthly with a final payment due on April 30, 1999.
Mr. Pincus has agreed not to compete with the Company for a period of one year
after he ceases to be employed by the Company.
 
The Company has entered into employment agreements with each of Stephen
Kleshinski, Vice President of Research and Development and Jason Harry, Ph.D.,
Vice President of Research Engineering. The employment agreements provide for
terms of five years commencing on June 1, 1993 and for three years commencing
July 1, 1994, respectively. Mr. Kleshinski has agreed for a period of 18 months
following termination of his employment, and Dr. Harry has agreed for a period
of 12 months following termination of his employment, not to compete with the
Company and they each have agreed to assign to the Company any inventions he
may have. The Company is obligated, however, to pay certain royalties to
Messrs. Kleshinski and Harry based on sales or licenses of products where
either Mr. Kleshinski or Dr. Harry, as the case may be, was the sole or joint
inventor. See "Business--Licensed Technology; Royalty Obligations."

STOCK OPTION PLANS
 
The 1994 Plan
 
The Nitinol Medical Technologies, Inc. 1994 Stock Option Plan (the "1994 Plan")
provides for the granting of stock options to acquire a maximum of 315,789
shares of Common Stock. As of July 31, 1996, no shares had been issued upon the
exercise of options granted under the 1994 Plan, 300,789 shares were subject to
outstanding options and 15,000 shares remained available for future grant. The
1994 Plan is administered by the Board of Directors; and, unless previously
terminated, shall terminate on May 31, 2004.
 
Under the 1994 Plan, options may be granted to employees, directors and
consultants, at the discretion of the Board of Directors. Incentive stock
options ("ISOs") may only be granted to individuals who, at the time of the
grant, are employees or directors of the Company. Non-qualified stock options
("NSOs") may be granted to employees, directors or consultants. The exercise
price of ISOs and NSOs shall be established by the Board of Directors, provided
that the exercise price must be at least equal to the fair market value per
share at the date of the grant. However, if ISOs are granted to persons owning,
directly or indirectly, at the time of the option grant, over 10% of the total
combined voting power of all classes of stock of the Company, the 1994 Plan
provides that the exercise price for such ISOs shall not be less than 110% of
fair market value per share at the date of the grant. Each ISO or NSO must
expire within ten years of the date of grant or at such earlier time as the
Board of Directors shall determine. Options are nontransferable, except by will
or the laws of descent and distribution. The amount and exercise price of
options granted under the 1994 Plan may be adjusted, at the discretion of the
Board of Directors, in the event of any change in the Company's capitalization
or in the event of any merger, consolidation or corporate reorganization where
the Company is the surviving corporation.
 
Any unexercised options held by a grantee whose relationship with the Company
ceases for any reason (other than retirement, death or disability) shall
immediately terminate. Upon cessation of a grantee's relationship with the
Company resulting from retirement, disability or death, the period during which
the grantee may exercise options
 
                                       45
<PAGE>
 
shall not exceed (i) one year from the date of termination in the case of
death, and (ii) three months from the date of termination in the case of
retirement or disability. However, in no event shall the exercise period extend
beyond the option term. Unexercised options shall terminate upon the
dissolution or liquidation of the Company or in the event of a merger,
consolidation or any corporate reorganization where the Company is not the
surviving corporation.
 
1996 Plan
 
The Nitinol Medical Technologies, Inc. 1996 Stock Option Plan (the "1996 Plan")
was approved by the Company's stockholders in July 1996.
   
The purpose of the 1996 Plan is to attract and retain key personnel. The 1996
Plan provides for the grant of options to acquire a maximum of 600,000 shares
of the Common Stock. As of July 31, 1996, no shares are subject to outstanding
options. The 1996 Plan permits the granting of ISOs or NSOs at the discretion
of the administrator of the 1996 Plan (the "Plan Administrator"). The Board of
Directors has appointed a Stock Option Committee of the Board as the Plan
Administrator. Subject to the terms of the 1996 Plan, the Plan Administrator
determines the terms and conditions of options granted under the 1996 Plan.
Options granted under the 1996 Plan are evidenced by written agreements which
contain such terms, conditions, limitations and restrictions as the Plan
Administrator deems advisable and which are not inconsistent with the 1996
Plan. ISOs may be granted to individuals who, at the time of grant, are
employees of the Company or its affiliates. NSOs may be granted to directors,
employees, consultants and other agents of the Company or its affiliates. The
1996 Plan provides that the Plan Administrator must establish an exercise price
for ISOs that is not less than the fair market value per share of the Common
Stock at the date of grant and an exercise price for NSOs of not less than 85%
of such fair market value. Each ISO must expire with ten years of the date of
grant. However, if ISOs are granted to a person owning more than 10% of the
voting stock of the Company, the 1996 Plan provides that the exercise price may
not be less than 110% of the fair market value per share at the date of grant
and that the term of such ISOs may not exceed five years. The Plan
Administrator has the authority to establish vesting periods for options
granted under the 1996 Plan, or to grant options which are fully vested at the
time of grant.     
 
An optionee whose relationship with the Company or any related corporation
ceases for any reason (other than termination for cause, death or total
disability, as such terms are defined in the 1996 Plan) may exercise options in
the three-month period following such cessation (unless such options terminate
or expire sooner by their terms), or in such longer period determined by the
Plan Administrator in the case of NSOs. Unexercised options granted under the
1996 Plan terminate upon a merger (other than a stock merger), reorganization
or liquidation of the Company; however, immediately prior to such a
transaction, optionees may exercise such options without regard to whether the
vesting requirements have been satisfied.
 
Options granted under the 1996 Plan convert into options to purchase shares of
another corporation involved in a stock merger with the Company, unless the
Company and such other corporation, in their sole discretion, determine that
such options terminate. Such converted options become fully vested without
regard to whether the vesting requirements in the option agreement for such
options have been satisfied, unless the Board of Directors determines
otherwise.
 
The option exercise price may be paid in full at the time the notice of
exercise of the option is delivered to the Company and must be paid in cash, by
bank certified or cashier's check or by personal check. Options are
nontransferable with certain exceptions. The Board has certain rights to
suspend, amend or terminate the 1996 Plan provided stockholder approval is
obtained.
 
The 1996 Directors' Stock Plan
 
The Nitinol Medical Technologies, Inc. 1996 Stock Option Plan for Non-Employee
Directors (the "1996 Directors' Stock Plan") was approved by the Company's
stockholders in July 1996. The 1996 Directors' Stock Plan is administered by
the Company's Board of Directors. Subject to the provisions of the 1996
Directors' Stock Plan, the Board has the authority to interpret the plan and
apply its provisions and to adopt, amend or rescind rules, procedures and forms
relating to it. The 1996 Directors' Stock Plan provides for the automatic grant
of nonstatutory stock options to purchase shares of Common Stock to directors
of the Company who are not employees of the Company and do not otherwise
receive compensation from the Company.
 
                                       46
<PAGE>
 
Under the 1996 Directors' Stock Plan, 150,000 shares of Common Stock have been
reserved for issuance of options. If any options granted under the 1996
Directors' Stock Plan shall for any reason expire or be cancelled or otherwise
terminated without having been exercised in full, the shares allocable to the
unexercised portion of such options shall again become available. The 1996
Directors' Stock Plan provides for the automatic grant of options to eligible
directors. Each eligible director who was serving on the Board on the effective
date of the 1996 Directors' Stock Plan automatically will receive an option to
purchase 10,000 shares of Common Stock at the current market price on the date
of grant, subject to vesting in equal monthly installments over a period of
three years. In the future, each nonemployee director who joins the Board will
automatically receive an initial grant of options to purchase 10,000 shares of
Common Stock at an exercise price equal to the fair market value per share at
the date of grant, subject to vesting in equal monthly installments over a
three year period. In each year other than the year in which a director
receives an initial grant of options, such director will automatically receive
options to purchase 2,500 shares of Common Stock which shall become fully-
vested six months after the date of grant.
 
The term of each option granted under the 1996 Directors' Stock Plan is 10
years. Options granted under the 1996 Directors' Stock Plan must be exercised
prior to the earlier of the scheduled expiration date or the date one year
following the date of termination of service.
 
The exercise price of each option under the 1996 Directors' Stock Plan must be
equal to the fair market value of the Common Stock subject to the option on the
date of the grant. The exercise price of each option is payable upon exercise
in cash. The 1996 Directors' Stock Plan also permits an optionee to pay the
exercise price of an option by delivery of an irrevocable direction to pledge
the optionee's shares to a securities broker or lender approved by the Company
as security for a loan and to deliver all or part of the loan proceeds to the
Company in payment of all or part of the exercise price and any withholding
taxes. Unless sooner terminated by the Board, the 1996 Directors' Stock Plan
will terminate in June 2006, and no further options may be granted pursuant to
the plan following the termination date.
 
OPTIONS GRANTED OUTSIDE OF THE PLANS
   
In addition to the ISOs and NSOs which may be granted under the 1994 Plan, as
of July 31, 1996 the Company has granted options to purchase an aggregate of
1,400,613 shares outside of the 1994 Plan, to certain of its employees,
consultants, executive officers and directors, of which 547,083 are vested and
the remainder of which vest upon the passage of time or the achievement of
certain milestones by the Company. Additionally, the Company has granted
certain "piggy-back" registration rights with respect to the shares underlying
such options. See "Description of Capital Stock--Registration Rights."     
 
401 (k) PROFIT SHARING PLAN & TRUST
 
In October 1995, the Company adopted a 401 (k) Profit Sharing Plan & Trust (the
"401 (k) Plan"), a tax-qualified plan covering all of its employees who are at
least 21 years of age and have completed three months of service with the
Company. Each employee may elect to reduce his or her current compensation by
up to 15%, subject to the statutory limit (a maximum of $9,500 in 1996) and
have the amount of the reduction contributed to the 401 (k) Plan. The 401 (k)
Plan provides that the Company may, as determined from time to time by the
Board of Directors, provide a matching contribution. In addition, the Company
may contribute an additional amount to the 401 (k) Plan, as determined by the
Board of Directors, which will be allocated based on the proportion of the
employee's compensation for the plan year to the aggregate compensation for the
plan year for all eligible employees. The Company has made no contributions to
date.
 
All employee contributions to the 401 (k) Plan are fully vested at all times.
Upon termination of employment, a participant may elect a lump sum distribution
or, if his or her total amount in the 401 (k) Plan is greater than $3,500, may
elect to receive benefits as retirement income.

                              CERTAIN TRANSACTIONS
 
In February 1996, the Company entered into an Agreement and Plan of Merger
pursuant to which InnerVentions, Inc., a wholly-owned subsidiary of Fletcher
Spaght, Inc. and the exclusive licensee of the technology relating to the
CardioSeal Septal Occluder, was merged with and into NMT Heart, Inc., a wholly-
owned subsidiary of the Company. Pursuant to the Agreement and Plan of Merger,
the Company acquired all the existing development, manufacturing and testing
equipment, patent licenses, know-how and documentation relating to the
manufacture of the CardioSeal Septal Occluder, which had been originally
developed by Bard, donated to Children's Hospital of Boston, then licensed to
InnerVentions. In connection with the merger, Fletcher Spaght, Inc. received
514,651 shares of Common Stock of NMT and warrants to purchase 111,818 shares
of Common Stock at an exercise price of $2.15 per share, which shares and
warrants are accompanied by certain "piggy-back" registration rights. See
"Description of Capital Stock--Registration Rights." NMT has also agreed to use
its best efforts to nominate a designee of Fletcher Spaght, Inc. as a director
of NMT. Certain of the Company's existing stockholders have agreed to vote
their shares of Common Stock in favor of such a designee.
   
In February 1996, the Company sold an aggregate of 3,787,104 shares of
Convertible Preferred Stock for an aggregate purchase price of $8,500,000
pursuant to the Convertible Stock Offering. Upon the completion of the
Offering, the outstanding shares of Convertible Preferred Stock will
automatically be converted into units, consisting of an aggregate of 1,993,212
shares of Common Stock and 37,871 shares of the Company's Redeemable Preferred
Stock. The Redeemable Preferred Stock will be redeemed by the Company upon
completion of the Offering at a redemption price of $4,250,000 plus accrued
dividends of approximately $150,000 thereon. See "Use of Proceeds." In
connection with the Convertible Stock Offering, the Company entered into a
Registration Rights Agreement with the purchasers of the Convertible Preferred
Stock, granting to such purchasers certain demand and "piggy-back"
registrations rights. See "Description of Capital Stock--Registration Rights."
Whitney Equity Partners, L.P. and Boston Scientific purchased 1,829,066 and
117,247 shares (on a common equivalent basis), respectively, in the Convertible
Stock Offering. Michael C. Brooks and Jeffrey R. Jay, M.D., each a Director of
the Company, are each a General Partner of J.H. Whitney & Co., an affiliate of
Whitney Equity Partners L.P.     
 
In connection with the foregoing transactions, in February 1996, the Company
also entered into a Termination Agreement with its existing stockholders
terminating a Stockholders Agreement dated as of April 30, 1987, as amended.
Pursuant to the Termination Agreement, the Company granted certain "piggy-back"
registration rights to existing stockholders. See "Description of Capital
Stock--Registration Rights."
 
In October 1995, C. Leonard Gordon, the Chairman of the Board of the Company,
received a non-qualified option to purchase 184,210 shares of the Company's
Common Stock at an exercise price of $2.15 per share. Of these options, (i)
105,263 vested immediately, (ii) 39,473 options will vest over three years
commencing with the closing of the acquisition in February 1996 of
InnerVentions; and (iii) 39,473 options will vest over three years commencing
with the closing of the Convertible Stock Offering which occurred in February
1996. In May 1994, in connection with Mr. Gordon's efforts in negotiating the
exclusive license agreement with Boston Scientific relating to the Company's
stent technology, Mr. Gordon received (i) a non-qualified stock option to
purchase 52,631 shares of the Company's Common Stock at an exercise price of
$1.14 to vest one year from the date of issuance, and (ii) $100,000 paid from
5% of payments received by the Company under the exclusive license agreement
with Boston Scientific. Mr. Gordon has entered into an oral arrangement with
the Company whereby Mr. Gordon will provide certain executive services as are
required by the Company and will be compensated for such services rendered in
an amount not to exceed $135,000 per year. The services Mr. Gordon performs for
the Company include serving as Chairman of the Board and consulting upon
various aspects of the Company's business including certain contractual
arrangements. The Company believes the terms of the arrangement are no less
favorable to the Company than terms that it could have obtained from an
unaffiliated third party. See Note 13 of Notes to the Consolidated Financial
Statements.
 
In April, 1987 the Company entered into a Technology Purchase Agreement with
Morris Simon, M.D. pursuant to which the Company has agreed to pay to Dr. Simon
certain royalty payments based on sales of products using the technology
invented by Dr. Simon relating to the SNF. Dr. Simon assigned a percentage of
his royalty payments to Beth Israel Hospital Association. See "Business--
Licensed Technology; Royalty Obligations." Dr. Simon has entered into an oral
arrangement with the Company whereby Dr. Simon will provide consulting services
as are required by the
 
                                       48
<PAGE>
 
Company and will be compensated for such services rendered in an amount not to
exceed $100,000 per year. Pursuant to this arrangement, Dr. Simon serves as
Scientific Director and provides related consulting services to the Company.
The Company believes the terms of the arrangement are no less favorable to the
Company than terms that it could have obtained from an unaffiliated third
party. See Note 13 of Notes to the Consolidated Financial Statements.
 
Pursuant to the Company's employment agreements with Messrs. Kleshinski and
Harry, respectively, the Company has agreed to pay certain royalties to Messrs.
Kleshinski and Harry based on sales or licenses of products where either Mr.
Kleshinski or Dr. Harry, as the case may be, was the sole or joint inventor.
See "Business--Licensed Technology; Royalty Obligations" and Note 8(d) of Notes
to the Consolidated Financial Statements.

                          DESCRIPTION OF CAPITAL STOCK
 
The authorized capital stock of the Company consists of 30,000,000 shares of
Common Stock, $.001 par value, 3,800,000 shares of Convertible Preferred Stock,
$.001 par value, 38,000 Redeemable Preferred Stock, $.001 par value and
3,000,000 shares of Preferred Stock, $.001 par value.
 
COMMON STOCK
   
As of July 31, 1996, there were 6,285,922 shares of Common Stock outstanding
and held of record by approximately 74 stockholders. There will be 9,285,922
shares of Common Stock outstanding after giving effect to the sale of the
shares of Common Stock offered hereby.     
 
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, and stockholders have
no right to cumulate their votes in the election of directors. 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 of Directors out of funds legally available
therefor. In the event of a liquidation, dissolution or winding up of the
Company, holders of Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities and liquidation preferences of any
outstanding shares of preferred stock. Holders of Common Stock have no
preemptive rights and no right to convert their Common Stock into any other
securities. There are no redemption or sinking fund provisions applicable to
the Common Stock. All outstanding shares of Common Stock are, and all shares of
Common Stock to be outstanding upon completion of the Offering will be, fully
paid and nonassessable.
 
PREFERRED STOCK
 
Upon the closing of the Offering, all outstanding shares of Convertible
Preferred Stock of the Company will convert automatically into shares of Common
Stock and Redeemable Preferred Stock, which shall be redeemed with a portion of
the net proceeds of the Offering. See "Use of Proceeds." Accordingly, no shares
of preferred stock will be outstanding immediately after the closing of the
Offering. The Board of Directors has the authority, without further action by
the stockholders, to issue shares 3,000,000 of preferred stock in one or more
series and to fix the designations, powers (including voting powers, if any)
preferences and relative participating, optional, conversion and other special
rights, and the qualifications, limitations and restrictions to each series.
This provision may be deemed to have a potential anti-takeover effect and the
issuance of preferred stock in accordance with such provision may delay or
prevent a change of control of the Company. In addition, although it presently
has no intention to do so, the Board of Directors, without stockholder
approval, could issue preferred stock with voting and conversion rights which
could adversely affect the voting power of the holders of Common Stock.
 
REGISTRATION RIGHTS
 
In connection with the Convertible Stock Offering, the purchasers of the
Convertible Preferred Stock were granted certain registration rights which
pertain to the shares of Common Stock to be issued upon the Conversion. At any
time after six months following the closing of the Offering, the Company is
obligated to effect three demand registrations (subject to certain limitations)
at the Company's expense upon the request of holders owning 25% or more of the
aggregate number of shares of Common Stock into which shares of Convertible
Preferred Stock have been converted. In addition, the Convertible Preferred
Stock purchasers were granted "piggy-back" registration rights immediately
(subject to certain limitations) at the Company's expense, as part of a
registration of the Company's securities for its own account or the account of
others. In addition, Junewicz & Co., Inc. and Furman Selz LLC, in connection
with the Convertible Stock offering, were issued warrants as ("Private
Placement Agent Warrants") to purchase 99,660 and 64,779 shares of Common
Stock, respectively. The Private Placement Agent Warrants grant the holders
thereof "piggy-back" registration rights as part of a registration of the
Company's securities for its own account or the account of others which are
exercisable at any time after the closing of the Offering. The holders of the
Private Placement Agent Warrants have agreed not to dispose of such warrants
for a period of 180 days after the date of this Prospectus.
 
                                       52
<PAGE>
 
Furthermore, whenever the Company proposes to register any of its securities
under the Securities Act, either for its own account or the account of others,
the Company is required each such time to notify Thomas M. Tully, the Company's
President and Chief Executive Officer, Fletcher Spaght, Inc. and Lloyd A.
Marks, M.D. and to include, at their request, therein their shares and shares
transferred by them to and for the benefit of their family members or
affiliates. The Company is required to bear the expenses of such "piggy-back"
registration rights. Such rights are subject to the right of the underwriter(s)
of the Offering to limit the number of shares being registered and other terms
and conditions. The Company has also granted similar "piggy-back" registration
rights to certain of its existing stockholders in consideration for their
agreement to terminate their Shareholders Agreement with the Company.
 
The existence of the registration rights described above may involve added
costs and complexity in the event the Company desires to register shares of
Common Stock in the future and could have an adverse effect on the market price
of Common Stock.
 
No shares of Common Stock are being registered on behalf of the Company's
securityholders in connection with the Offering.
 
LIMITATIONS ON LIABILITY OF OFFICERS AND DIRECTORS
 
The Company's Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws provide broadly for indemnification of the officers and
directors of the Company. In addition, the Amended and Restated Certificate of
Incorporation provides that, to the fullest extent permitted by Delaware law,
no director shall be personally liable to the Company or its stockholders for
monetary damages for any breach of fiduciary duty by such director in his
capacity as a director.
 
DELAWARE ANTI-TAKEOVER STATUTE
 
The Company is subject to the provisions of Section 203 of the Delaware General
Corporation Law. In general, the statute prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date that the person became
an interested stockholder unless (with certain exceptions) the business
combination or the transaction in which the person became an interested
stockholder is approved in a prescribed manner. Generally, a "business
combination" includes a merger, asset or stock sale, or other transaction
resulting in a financial benefit to the stockholder. Generally, an "interested
stockholder" is a person who, together with affiliates and associates, owns or
(within three years prior, did own) 15% or more of the corporation's voting
stock.
 
TRANSFER AGENT AND REGISTRAR
 
American Stock Transfer and Trust Company will act as transfer agent and
registrar for the Common Stock.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
Upon completion of the Offering, the Company will have a total of 9,285,922
shares of Common Stock outstanding (9,735,922 shares if the Underwriters' over-
allotment option is exercised in full). Of these shares, the 3,000,000 shares
of Common Stock offered hereby (3,450,000 shares if the Underwriters' over-
allotment option is exercised in full) will be freely tradable without
restriction or registration under the Securities Act, by persons other than
affiliates of the Company. The remaining 6,285,922 shares of Common Stock
outstanding are "restricted shares" as that term is defined by Rule 144
promulgated under the Securities Act. Under Rule 144 (and subject to the
conditions thereof) approximately 3,605,691 shares of the restricted shares
will become eligible for sale upon completion of the Offering. The Company's
officers and directors and certain other stockholders of the Company (who in
the aggregate will hold 6,248,499 shares of the restricted securities upon
completion of the Offering) have agreed to enter into lock-up agreements which
provide that they will not directly or indirectly, offer, sell, offer to sell,
grant any option to purchase or otherwise sell or dispose of any shares of
Common Stock or other capital stock of the Company, or any securities
convertible into, exercisable, or exchangeable for, any shares of Common Stock
or other capital stock of the Company without the prior written consent of J.P.
Morgan Securities, Inc. on behalf of the Underwriters, for a period of 180 days
from the date of this Prospectus, subject to certain limited exceptions. See
"Underwriting."     
   
As of July 31, 1996, options to purchase a total of 1,701,390 shares of Common
Stock were outstanding with a weighted average exercise price of $2.50 per
share, of which options to purchase 700,846 shares of Common Stock were
exercisable. In addition, as of such date, an additional 15,000 shares of
Common Stock were available for future option grants under the 1994 Plan. In
June 1996, the Company adopted, subject to stockholder approval, the 1996 Plan
and the 1996 Directors' Stock Plan, which include 600,000 and 150,000 shares
available for future option grants, respectively. As of July 31, 1996 no
options have been granted under the 1996 Plan. Upon adoption of the 1996
Directors' Stock Plan, options to purchase 10,000 shares of Common Stock at the
initial public offering price per share will be granted to four nonemployee
directors, subject to stockholder approval of the plan. As of July 31, 1996,
Common Stock purchase warrants to purchase a total of 281,520 shares of Common
Stock were outstanding with a weighted average price of $3.34 per share. The
Company's officers, directors and certain other stockholders of the Company
holding an aggregate of 1,350,587 shares issuable upon the exercise of options
and warrants have agreed to enter into lock-up agreements. Rule 701 under the
Securities Act provides that, beginning 90 days after the date of this
Prospectus, shares of Common Stock acquired on the exercise of outstanding
options may be resold subject to certain provisions of Rule 144. The Company
intends to file registration statements under the Securities Act to register
shares of Common Stock included in its option plans, shares of Common Stock
subject to outstanding stock options granted outside of such plans and shares
of Common Stock issuable upon the exercise of certain warrants. See
"Description of Capital Stock--Registration Rights."

The nature of the Underwriters' obligations under the Underwriting Agreement is
such that all of the Common Stock being offered, excluding shares covered by
the over-allotment option granted to the Underwriters, must be purchased if any
are purchased.
 
The Representatives have advised the Company that the several Underwriters
propose to offer the Common Stock to the public initially at the public
offering price set forth on the cover page of this Prospectus and may offer the
Common Stock to selected dealers at such price less a concession not to exceed
$    per share. The Underwriters may allow, and such dealers may reallow, a
concession to other dealers not in excess of $    per share. After the public
offering of the Common Stock, the public offering price and other selling terms
may be changed by the Representatives.
   
The Company has granted the Underwriters an option, exercisable within 30 days
after the date of this Prospectus, to purchase up to an additional 450,000
shares of Common Stock from the Company at the same price per share to be paid
by the Underwriters for the other shares offered hereby. If the Underwriters
purchase such additional shares pursuant to the option, each of the
Underwriters will be committed to purchase such additional shares in
approximately the same proportion as set forth in the above table. The
Underwriters may exercise the option only to cover over-allotments, if any,
made in connection with the distribution of Common Stock offered hereby.     
 
Prior to the Offering, there has been no public market for the Common Stock.
The initial public offering price has been determined by negotiations between
the Company and the Representatives. Among the factors considered in
determining the initial offering price include the prevailing market
conditions, the market valuations of certain publicly traded companies, revenue
and earnings of the Company and comparable companies in recent periods,
estimates of the business potential and prospects of the Company, the
experience of the Company's management and the position of the Company in its
industry.
 
The Representatives have advised the Company that they do not expect sales to
accounts over which they exercise discretionary authority will exceed 5% of the
shares of Common Stock offered hereby.
 
The Company and its directors and executive officers and certain stockholders
have agreed not to offer, sell or otherwise dispose of, any Common Stock or any
securities convertible into Common Stock or register for sale under the
Securities Act any Common Stock, for a period of 180 days after the date of
this Prospectus without the prior written consent of J.P. Morgan Securities
Inc., subject to certain limited exceptions. See "Shares Eligible for Future
Sale."
 
The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute
to payments the Underwriters may be required to make in respect thereof.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Nitinol Medical Technologies, Inc.:
 
We have audited the accompanying consolidated balance sheets of Nitinol Medical
Technologies, Inc. (a Delaware corporation) and subsidiary as of December 31,
1994 and 1995, and the related consolidated statements of operations,
stockholders' equity (deficit) and cash flows for each of the three years in
the period ended December 31, 1995. 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 financial statements referred to above present fairly, in
all material respects, the financial position of Nitinol Medical Technologies,
Inc. and subsidiary as of December 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1995, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 (1) OPERATIONS
 
   Nitinol Medical Technologies, Inc. (NMT or the Company) designs, develops
   and markets innovative medical devices that utilize advanced materials and
   are delivered by minimally invasive procedures. The Company's products are
   designed to offer alternative approaches to existing complex treatments,
   thereby reducing patient trauma, shortening procedure, hospitalization and
   recovery times, and lowering overall treatment costs. The Company's
   patented medical devices include self-expanding stents, vena cava filters
   and septal repair devices. At this time, the Company's stents are in
   European clinical trials for certain indications, its vena cava filters
   are marketed in the United States and abroad, and the Company is
   completing the development of its septal repair device. The Company is
   subject to a number of risks similar to those of other companies in this
   stage of development, including uncertainties regarding the development of
   commercially viable products, competition from alternative procedures and
   larger companies, dependence on key personnel, government regulation and
   the ability to obtain adequate financing to fund product development. See
   "Risk Factors" on pages 6-12 of this Prospectus.
 
 (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
   (a) Principles of Consolidation
 
   The accompanying Consolidated Financial Statements include the accounts of
   the Company and its wholly owned subsidiary. All intercompany transactions
   and balances have been eliminated in consolidation.
 
   (b) Management Estimates
 
   The preparation of accrual based financial statements in conformity with
   generally accepted accounting principles requires management to make
   estimates and assumptions that affect the reported amounts of assets and
   liabilities and disclosure of contingent assets and liabilities at the
   date of the financial statements, and the reported amounts of revenues and
   expenses during the reporting periods. Actual results could differ from
   those estimates.
 
   (c) Interim Financial Statements
 
   The accompanying Consolidated Financial Statements as of June 30, 1996 and
   for the six months ended June 30, 1995 and 1996 are unaudited. In
   management's opinion, these unaudited Consolidated Financial Statements
   have been prepared on the same basis as the audited Consolidated Financial
   Statements and include all adjustments, consisting of only normal
   recurring adjustments, necessary for a fair presentation of the results
   for such periods. The unaudited results for the six months ended June 30,
   1996 are not necessarily indicative of the results expected for the fiscal
   year ending December 31, 1996.
 
   (d) Cash and Cash Equivalents
 
   The Company considers all investments with maturities of 90 days or less
   from the date of purchase to be cash equivalents. At June 30, 1996, cash
   equivalents consist of money market accounts, commercial paper and short-
   term mutual funds that invest in U.S. government obligations. In
   accordance with Statement of Financial Accounting Standards (SFAS) No.
   115, Accounting for Certain Investments in Debt and Equity Securities, the
   Company considers its cash equivalents, which are carried at market and
   approximate cost, as available-for-sale.
 
   (e) Inventories
 
   Inventories are stated at the lower of cost (first-in, first-out) or
   market and consist of the following:

   (f) Financial Instruments
 
   The estimated fair value of the Company's financial instruments, which
   include cash and cash equivalents, accounts receivable and debt,
   approximates their reported amounts.
 
   (g) Concentration of Credit Risk
 
   SFAS No. 105, Disclosure of Information About Financial Instruments with
   Off-Balance-Sheet Risk and Financial Instruments with Concentration of
   Credit Risk, requires disclosure of any significant off-balance-sheet and
   credit risk concentrations. Financial instruments that subject the Company
   to credit risk consist primarily of trade accounts receivable. The Company
   utilizes primarily one distributor for the sales of its filter products.
   This distributor had amounts due to the Company of approximately $162,000,
   $267,000 and $584,000 as of December 31, 1994 and 1995 and June 30, 1996,
   respectively. This distributor accounted for 83%, 93%, 95%, 94% and 96% of
   product revenues for fiscal 1993, 1994 and 1995 and for the six months
   ended June 30, 1995 and 1996, respectively.
 
   (h) Depreciation and Amortization
 
   The Company provides for depreciation and amortization by charges to
   operations using the straight-line method, which allocates the cost of
   property and equipment over the following estimated useful lives:
 
                                                           ---------

</TABLE>
 
   (i) Revenue Recognition
 
   The Company records product sales upon shipment as products sold to the
   Company's primary distributor are not subject to a right of return for
   unsold product. License fees and product development revenue are
   recognized as earned.
 
   The Company expects to recognize $500,000 of license fees, which are
   currently recorded as deferred revenue, when the 24-month refund period
   expires in November 1996 (see Note 6).
 
   (j) Net Income (Loss) per Common and Common Equivalent Share
 
   Net income (loss) per common and common equivalent share is based on the
   weighted-average number of shares of common stock and common stock
   equivalents outstanding during the respective periods. All shares of
   capital stock, options and warrants issued during the 12 months
   immediately preceding the anticipated initial public offering were treated
   as if they had been outstanding for all periods, in accordance with the
   Securities and Exchange Commission rules and regulations, calculated under
   the treasury-stock method and based on the estimated initial public
   offering share price appearing on the cover of this Prospectus. Pro forma
   net income (loss) per common and common equivalent share has not been
   presented as the results are not materially different from historical net
   income (loss) per common and common equivalent share.

   (k) Postretirement Benefits
 
   The Company has no material obligations for postretirement benefits.
 
   (l) Unaudited Pro Forma Presentation
 
   The unaudited pro forma consolidated balance sheet as of June 30, 1996 re-
   flects the following events, which will occur upon the closing of the
   Company's proposed initial public offering: (i) the automatic conversion
   of all outstanding convertible preferred stock into 1,993,212 shares of
   common stock and 37,371 shares of redeemable preferred stock and (ii) the
   reclassification of the redemption value of preferred stock to redeemable
   preferred stock liquidation liability as the redeemable preferred stock
   will be redeemed utilizing proceeds of the Company's proposed initial pub-
   lic offering.
 
 (3) PURCHASE OF TECHNOLOGY AND OTHER ASSETS
 
   In February 1996, the Company issued 514,651 shares of its common stock
   and warrants to purchase 111,818 shares of common stock at $2.15 per share
   for the purchase of certain technology and related fixed assets. The
   Company has valued the common stock issued in this transaction at $2.15
   per share, which represents the fair value as determined by its Board of
   Directors and supported by an appraisal. The Company is required to pay
   certain future royalties as defined in the agreement. The acquired
   technology relates to a septal repair device for which the Company expects
   to conduct human clinical trials. At the time of the acquisition, it was
   determined that the commercial feasibility of the purchased technology was
   uncertain, and accordingly, the Company charged the amount of the purchase
   price allocated to the technology to operations as in-process research and
   development. The amount allocated to laboratory and computer equipment
   represents the estimated fair value at the date of acquisition of the
   acquired laboratory and computer equipment which have alternative future
   uses. The aggregate purchase price and acquisition costs incurred of
   $1,409,917 were allocated as follows:
 
                                                             -------

 (4) INCOME TAXES
 
   The Company uses the liability method to account for income taxes in
   accordance with SFAS No. 109, Accounting for Income Taxes.
 
   Prior to October 19, 1995, the Company elected to be taxed as an S
   corporation for federal and state income tax purposes. Accordingly, the
   accompanying Consolidated Financial Statements do not include a provision
   for income taxes for 1993, 1994 and the first 10 1/2 months of 1995. The
   provision for income taxes in the accompanying consolidated statement of
   operations for the period from October 19, 1995 to December 31, 1995
   consists of the following:
 
                                                               -----

   The accompanying consolidated statements of operations do not contain a
   pro forma income tax adjustment for periods prior to the termination of
   the S corporation election. If the election to be treated as an
   S corporation was not made, the Company would have been subject to federal
   and state corporate income taxes. However, the Company would have had
   sufficient net operating loss carryforwards to offset income in all
   periods presented.

 (5) LOAN FROM DISTRIBUTOR
 
   The Company has an exclusive distribution agreement with an unrelated
   third party to provide for the sale and distribution of the Simon Nitinol
   Filter (SNF). In connection with this agreement, the Company received a
   loan of $1,500,000 from the distributor in 1992. The agreement calls for
   the repayment of this loan by the Company through certain minimum
   purchases of the SNF by the distributor, as defined in the agreement. In
   the event that the loan is not fully repaid upon expiration or termination
   of the agreement, the amount outstanding becomes due and payable in
   monthly installments. Based on projected sales levels for 1996, the
   Company expects that the amount outstanding under the loan agreement at
   December 31, 1995 and June 30, 1996 will be repaid in full in 1996.
   Accordingly, the total outstanding amount has been classified as current
   in the accompanying consolidated balance sheets as of December 31, 1995
   and June 30, 1996.
 
 (6) DEFERRED REVENUE
 
   On November 22, 1994, the Company licensed exclusive, worldwide rights,
   including the right to sublicense to others, to develop, produce and
   market its stent technology to an unrelated third party (the Licensee). In
   connection with the signing of the license agreement, the Company received
   $500,000 in consideration for the license granted and an additional
   $500,000 upon issuance of the United States patent for a specific stent.
   The Company may be required to refund varying amounts of such payments
   based on the occurrence of certain events, as defined in the license
   agreement. To date, no such event has occurred. The Company deferred
   recognition as revenue of amounts that may be subject to refund until the
   expiration of the refund period. The final refund period expires in
   November 1996. The Company also received $272,500 from the Licensee in
   1994 which is nonrefundable and is to be credited against future license
   fees payable to the Company, as defined. This amount is included in
   license fees in the accompanying consolidated statements of operations in
   1994. During 1995 and the six months ended June 30, 1996, the Company
   received additional nonrefundable license fees upon the achievement of
   certain milestones, as defined in the license agreement.
 
   In 1994, the Company also received a $100,000 advance from the Licensee
   under a product development program for the reimbursement of costs the
   Company incurred related to the activities of product development,
   registration and transfer of technology to the Licensee. For the years
   ended December 31, 1994 and 1995 and for the six months ended June 30,
   1995 and 1996, the Company received $38,051, $491,857, $268,915 and
   $79,027, respectively, of reimbursements for development program costs.
   These reimbursed amounts are included in revenues in the accompanying
   consolidated statements of operations.

(10) PREFERRED STOCK
 
   In February 1996, the Board of Directors authorized 3,800,000 shares of
   convertible preferred stock and 38,000 shares of redeemable preferred
   stock. The Company then sold 3,787,104 shares of preferred stock at $2.24
   per share, resulting in net proceeds to the Company of approximately
   $7,500,000. The Company has recorded the redemption value of the
   convertible preferred stock outside of stockholder's equity (deficit) as
   of June 30, 1996.
 
   On July 9, 1996 the Company authorized 3,000,000 shares of undesignated
   preferred stock.
 
   (a) Convertible Preferred Stock
 
   The convertible preferred stockholders maintain the following rights and
   privileges.
 
     Voting. The convertible preferred stockholders are entitled to vote
     with the common stockholders based on the number of votes that they
     would receive upon conversion.
 
     Conversion. The convertible preferred stockholders may convert their
     preferred stock at any time. Each share of convertible preferred stock
     is convertible into one conversion unit. A conversion unit consists of
     (i) 1/1.9 share of common stock, subject to certain antidilution
     adjustments and (ii) one one-hundredth share of redeemable preferred
     stock. The convertible preferred stock automatically converts into an
     equal number of conversion units upon an initial public offering
     resulting in gross proceeds to the Company of at least $22,000,000 and
     a minimum price of $12.77 per share or a sale of the Company resulting
     in gross proceeds to the stockholders of at least $100,000,000.
 
     Liquidation. In the event of liquidation, dissolution or winding up of
     the Company, the holders of the convertible preferred stock are
     entitled to an amount equal to the greater of (i) the liquidation
     preference, $2.24 per share at March 31, 1996, plus any accrued and
     unpaid dividends or (ii) the amount the holders of convertible
     preferred stock would be entitled to receive if all shares of
     convertible preferred stock had been converted immediately prior to any
     liquidation, dissolution or winding up.
 
     Dividends. The holders of the convertible preferred stock shall be
     entitled to receive dividends if and when declared by the Board of
     Directors. Dividends payable on the convertible preferred stock shall
     begin to accrue in May 1996 at an annual rate equal to 8% based on the
     liquidation preference described above.
 
   (b) Redeemable Preferred Stock
 
   The redeemable preferred stockholders maintain the following rights and
   privileges.
 
     Voting. The holders of redeemable preferred stock shall not have any
     right to vote unless required by law.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 
     Redemption. On the closing of a qualified initial public offering or a
     qualified sale transaction, as defined above, each share of redeemable
     preferred stock shall automatically be redeemed at a price equal to
     $4,250,000 divided by the number of shares of redeemable preferred
     stock outstanding, plus (i) all accrued and unpaid dividends and (ii)
     any dividend amounts due to the redeemable preferred stockholders.
 
     Liquidation. In the event of liquidation, dissolution or winding up of
     the Company, the holders of the redeemable preferred stock shall be
     entitled to receive an amount equal to the redemption liquidation
     preference plus any accrued and unpaid dividends.
 
     Dividends. The holders of the redeemable preferred stock shall be
     entitled to receive dividends if and when declared by the Board of
     Directors. Dividends on the redeemable preferred stock shall begin to
     accrue from the issuance date of the redeemable preferred stock at an
     annual rate equal to 16% based on the redemption liquidation
     preference.
 
(11) STOCK OPTIONS AND WARRANTS
 
   (a) Nonqualified Stock Options
 
   The Company granted nonqualified options to various officers/stockholders
   and members of the Board of Directors to purchase shares of common stock
   at a given exercise price per share. The options become exercisable in
   full or in part at issuance or within one to four years of the date of
   issuance. All unexercised grants expire on the earlier of approximately
   five to ten years from date of issuance or 90 days after termination of
   service as an officer, director, employee and/or consultant.
 
   (b) Stock Option Plans
 
   1994 Stock Option Plan. In May 1994, the Board of Directors approved an
   incentive stock option plan (the 1994 Plan), which authorizes the Company
   to issue options to purchase up to 315,789 shares of the Company's common
   stock under the 1994 Plan. The Company may grant options to officers, key
   employees, directors and consultants of the Company at an exercise price
   not less than fair market value as determined by the Board of Directors.

   July 1996.
      
   The 1996 Plan provides for the grant of options to acquire a maximum of
   600,000 shares of the common stock. As of July 31, 1996, no shares are
   subject to outstanding options. The 1996 Plan permits the granting of
   incentive stock options or nonstatutory stock options at the discretion of
   the administrator of the 1996 Plan (the Plan Administrator). The Board of
   Directors has appointed a Stock Option Committee of the Board as the Plan
   Administrator. Subject to the terms of the 1996 Plan, the Plan
   Administrator determines the terms and conditions of options granted under
   the 1996 Plan.     
 
   The 1996 Directors Stock Plan. The Nitinol Medical Technologies, Inc. 1996
   stock option plan for non-employee directors (the 1996 Directors' Stock
   Plan) was approved by the Company's stockholders in July 1996. The 1996
   Directors' Stock Plan provides for the automatic grant of nonstatutory
   stock options to purchase shares of common stock to directors of the
   Company who are not employees of the Company and do not otherwise receive
   compensation from the Company.
 
   Under the 1996 Directors' Stock Plan 150,000 shares of common stock have
   been reserved for issuance of options. The 1996 Directors' Stock Plan
   provides for the automatic grant of options to eligible directors. Each
   eligible director serving on the Board on the effective date of the 1996
   Directors' Stock Plan automatically received an option to purchase 10,000
   shares of common stock at a price equal to the initial public offering
   price of this offering, subject to vesting in three equal monthly
   installments over a period of three years. In the future, each nonemployee
   director who joins the Board will automatically receive an initial grant
   of options to purchase 10,000 shares of common stock at an exercise price
   equal to the fair market value per share at the date of grant, subject to
   vesting in equal monthly installments over a three year period. In each
   year other than the year in which a director receives an initial grant of
   options, such director will automatically receive options to purchase
   2,500 shares of common stock which shall become fully-vested six months
   after the date of grant.

ITEM 14. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
  Delaware General Corporation Law, Section 102(b)(7), enables a corporation
in its original certificate of incorporation, or an amendment thereto validly
approved by stockholders, to eliminate or limit personal liability of members
of its Board of Directors for violations of a director's fiduciary duty of
care. However, the elimination or limitation shall not apply where there has
been a breach of the duty of loyalty, failure to act in good faith,
intentional misconduct or a knowing violation of a law, the payment of a
dividend or approval of a stock repurchase which is deemed illegal or an
improper personal benefit is obtained. Articles Eighth, Ninth and Tenth of the
Company's Amended and Restated Certificate of Incorporation includes the
following language:
 
  "EIGHTH. A. Each person who was or is made a party or is threatened to be
made a party to or is otherwise involved in any action, suit, or proceeding,
whether civil, criminal, administrative, or investigative (hereinafter a
"proceeding"), by reason of the fact that he or she is or was a director,
officer, employee, or agent of the Corporation or any of its direct or
indirect subsidiaries or is or was serving at the request of the Corporation
as a director, officer, employee, or agent of any other corporation or of a
partnership, joint venture, trust, or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a
director, officer, employee, or agent or in any other capacity while serving
as a director, officer, employee, or agent, shall be indemnified and held
harmless by the Corporation to the fullest extent authorized by the Delaware
General Corporation Law, as the same exists or may hereafter be amended (but,
in the case of any such amendment, only to the extent that such amendment
permits the Corporation to provide broader indemnification rights than
permitted prior thereto), against all expense, liability, and loss (including
attorneys' fees, judgments, fines, excise or other taxes assessed with respect
to an employee benefit plan, penalties, and amounts paid in settlement)
reasonably incurred or suffered by such indemnitee in connection therewith,
and such indemnification shall continue as to an indemnitee who has ceased to
be a director, officer, employee, or agent and shall inure to the benefit of
the indemnitee's heirs, executors, and administrators; provided, however,
that, except as provided in Paragraph C of this Article EIGHTH with respect to
proceedings to enforce rights to indemnification, the Corporation shall
indemnify any such indemnitee in connection with a proceeding (or part
thereof) initiated by such indemnitee only if such proceeding (or part
thereof) was authorized by the Board of Directors of the Corporation.
 
                                     II-1
<PAGE>
 
  B. The right to indemnification conferred in Paragraph A of this Article
EIGHTH shall include the right to be paid by the Corporation the expenses
incurred in defending any proceeding for which such right to indemnification
is applicable in advance of its final disposition (hereinafter an "advancement
of expenses"); provided, however, that, if the Delaware General Corporation
Law requires, an advancement of expenses incurred by an indemnitee in his or
her capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such indemnitee, including, without limitation,
service to an employee benefit plan) shall be made only upon delivery to the
Corporation of an undertaking (hereinafter an "undertaking"), by or on behalf
of such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal (hereinafter a "final adjudication") that such indemnitee is not
entitled to be indemnified for such expenses under this Article EIGHTH or
otherwise.
 
  C. The rights to indemnification and to the advancement of expenses
conferred in Paragraphs A and B of this Article EIGHTH shall be contract
rights. If a claim under Paragraph A or B of this Article EIGHTH is not paid
in full by the Corporation within sixty days after a written claim has been
received by the Corporation, except in the case of a claim for an advancement
of expenses, in which case the applicable period shall be 20 days, the
indemnitee may at any time thereafter bring suit against the Corporation to
recover the unpaid amount of the claim. If successful in whole or in part in
any such suit, or in a suit brought by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the
indemnitee shall be entitled to be paid also the expense of prosecuting or
defending such suit. In (i) any suit brought by the indemnitee to enforce a
right to indemnification hereunder (but not in a suit brought by an indemnitee
to enforce a right to an advancement of expenses) it shall be a defense that
the indemnitee has not met any applicable standard for indemnification set
forth in the Delaware General Corporation Law, and (ii) any suit by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking, the Corporation shall be entitled to recover such expenses upon a
final adjudication that the indemnitee has not met any applicable standard for
indemnification set forth in the Delaware General Corporation Law. Neither the
failure of the Corporation (including its Board of Directors, independent
legal counsel, or its stockholders) to have made a determination prior to the
commencement of such suit that indemnification of the indemnitee is proper in
the circumstances because the indemnitee has met the applicable standard of
conduct set forth in the Delaware General Corporation Law, nor an actual
determination by the Corporation (including its Board of Directors,
independent legal counsel, or its stockholders) that the indemnitee has not
met such applicable standard of conduct, shall create a presumption that the
indemnitee has not met the applicable standard of conduct or, in the case of
such a suit brought by the indemnitee, be a defense to such suit. In any suit
brought by the indemnitee to enforce a right to indemnification or to an
advancement of expenses hereunder, or by the Corporation to recover an
advancement of expenses pursuant to the terms of an undertaking, the burden of
proving that the indemnitee is not entitled to be indemnified, or to such
advancement of expenses, under this Article EIGHTH or otherwise, shall be on
the Corporation.
 
  D. The rights to indemnification and to the advancement of expenses
conferred in this Article EIGHTH shall not be exclusive of any other right
which any person may have or hereafter acquire under any statute, this
certificate of incorporation, by-law, agreement, vote of stockholders or
disinterested directors, or otherwise.
 
  E. The Corporation may maintain insurance, at its expense, to protect itself
and any director, officer, employee, or agent of the Corporation or another
corporation, partnership, joint venture, trust, or other enterprise against
any expense, liability, or loss, whether or not the Corporation would have the
power to indemnify such person against such expense, liability, or loss under
the Delaware General Corporation Law.
 
  F. The Corporation's obligation, if any, to indemnify any person who was or
is serving as a director, officer, employee, or agent of any direct or
indirect subsidiary of the Corporation or, at the request of the Corporation,
of any other corporation or of a partnership, joint venture, trust, or other
enterprise shall be reduced by any amount such person may collect as
indemnification from such other corporation, partnership, joint venture,
trust, or other enterprise.
 
  G. Any repeal or modification of the foregoing provisions of this Article
EIGHTH shall not adversely affect any right or protection hereunder of any
person in respect of any act or omission occurring prior to the time of such
repeal or modification.
 
                                     II-2
<PAGE>
 
  NINTH. No director of the Corporation shall be liable to the Corporation or
any of its stockholders for monetary damages for breach of fiduciary duty as a
director, provided that this provision does not eliminate the liability of the
director (i) for any breach of the director's duty of loyalty to the
Corporation or its stockholders, (ii) for acts or omissions not in good faith
or which involve intentional misconduct or a knowing violation of law, (iii)
under Section 174 of Title 8 of the Delaware Code, or (iv) for any transaction
from which the director derived an improper personal benefit. For purposes of
the prior sentence, the term "damages" shall, to the extent permitted by law,
include without limitation, any judgment, fine, amount paid in settlement,
penalty, punitive damages, excise or other tax assessed with respect to an
employee benefit plan, or expense of any nature (including, without
limitation, counsel fees and disbursements). Each person who serves as a
director of the Corporation while this Article NINTH is in effect shall be
deemed to be doing so in reliance on the provisions of this Article NINTH, and
neither the amendment or repeal of this Article NINTH, nor the adoption of any
provision of this Certificate of Incorporation inconsistent with this Article
NINTH, shall apply to or have any effect on the liability or alleged liability
of any director of the Corporation for, arising out of, based upon, or in
connection with any acts or omissions of such director occurring prior to such
amendment, repeal, or adoption of an inconsistent provision. The provisions of
this Article NINTH are cumulative and shall be in addition to and independent
of any and all other limitations on or eliminations of the liabilities of
directors of the Corporation, as such, whether such limitations or
eliminations arise under or are created by any law, rule, regulation, by-law,
agreement, vote of stockholders or disinterested directors, or otherwise.
 
  TENTH. Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under
the provisions of Section 291 of Title 8 of the Delaware Code or on the
application of trustees in dissolution or of any receiver or receivers
appointed for the Corporation under the provisions of Section 279 of Title 8
of the Delaware Code order a meeting of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the
case may be, to be summoned in such manner as the said court directs. If a
majority in number representing three-fourths in value of the creditors or
class of creditors, and/or of the stockholders or class of stockholders of the
Corporation, as the case may be, agree to any compromise or arrangement and to
any reorganization of the Corporation as consequence of such compromise or
arrangement, the said compromise or arrangement and the said reorganization
shall, if sanctioned by the court to which the said application has been made,
be binding on all the creditors or class of creditors, and/or on all the
stockholders or class of stockholders, of the Corporation, as the case may be,
and also on the Corporation."
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
   
  In February 1996, the Company sold an aggregate of 3,787,104 shares of
Convertible Preferred Stock for an aggregate purchase price of $8,500,000. The
Company believes that each such issuance and sale was exempt from registration
pursuant to Section 4(2) of the Securities Act and Regulation D promulgated
thereunder. Warrants to purchase 164,439 shares of Common Stock at an exercise
price of $4.26 were also issued for nominal consideration to certain brokers
that assisted the Company in the Convertible Stock Offering. The Company
believes that each such issuance and sale was exempt from registration
pursuant to Section 4(2) of the Securities Act.     
   
  In the last three years, the Company has issued options for the purchase of
an aggregate of 300,777 shares of Common Stock under the 1994 Plan, none of
which have been exercised. The Company believes that each of the foregoing
transactions was exempt from registration pursuant to Section 4(2) of the
Securities Act.     
 
  Each purchaser of the securities described above has represented that he or
she understands that the securities acquired may not be sold or otherwise
transferred absent registration under the Act or the availability of an
exemption from the registration requirements of the Act, and each certificate
evidencing the securities owned by each purchaser bears or will bear upon
issuance a legend to that effect.

ITEM 17. UNDERTAKINGS.
 
  The Company 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 foregoing provisions, or otherwise, the Company has been ad-
vised that in the opinion of the Securities and Exchange Commission such in-
demnification 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 appro-
priate 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 Company hereby undertakes that, for purposes of determining any liabil-
ity under the Securities Act, the information omitted from the form of pro-
spectus 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.

  The Company hereby undertakes that, 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.

                                                                    Exhibit 10.7

     This agreement ("Agreement") is made this 19th day of May, 1992 by and
between Nitinol Medical Technologies, Inc., a Delaware corporation ("NMT")
having its principal place of business at 175-P New Boston Street, Woburn, MA
01801 and C.R. Bard Inc., a New Jersey corporation by its division, Bard
Radiology ("Bard"), which division has its principal office at 10115 Highway
142, Covington, GA  30209.

                                    RECITALS

     WHEREAS, NMT has developed a vena cava filter made of nitinol and a
delivery system, collectively called the Simon Nitinol Filter (the "SNF"),
obtained a United States patent covering the SNF, regulatory permission to
market the SNF, and commenced the manufacture and distribution of the SNF in the
United States and other parts of the world;

     WHEREAS, NMT and Bard desire that Bard, which distributes devices to
interventional radiologists and surgeons, be the distributor in the United
States and certain other parts of the world of the SNF and such other NMT
designed devices as the parties may hereafter mutually agree;

                                   AGREEMENT

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

     1. Product. "Product" shall include (a) the SNF and any changes,
        -------                                                      
improvements or modifications thereto; and (b) any other vena cava filter and
delivery system for vena cava filters which NMT may develop. The SNF presently
consists of two separate sterile kits packaged as one unit. One kit contains the
nitinol wire vena cava filter device pre-loaded in its storage tube and packaged
together with its preassembled delivery system. The other kit contains the
introduction catheter, dilator catheter, guidewire, venepuncture needle and
scalpel. The SNF comes in three different configurations, one for femoral
delivery, one for jugular delivery and one for antecubital delivery. The SNF
shall be designated in all labeling and advertising as the "Simon Nitinol
Filter".

     2. Territory. The "Territory" shall be the United States. In addition, the
        ---------                                                              
Territory includes Canada, Mexico, Puerto Rico, Brazil, Denmark, Norway, Sweden
and Australia, provided, however, that NMT may in the future, on sixty (60) days
prior written notice, exclude from the Territory any such non U.S. countries in
which Bard or its affiliates are not actively engaged in or actively taking
steps to engage in distributing the Product.

     3. Distributorship. NMT hereby appoints Bard as the exclusive distributor
        ---------------                                                       
of the Product in the Territory.

     4. Representations and Warranties.
        ------------------------------ 

     (a) NMT represents and warrants that:

     (i) NMT is duly incorporated and validly existing under Delaware law and
     has full power and authority to enter into this Agreement; this Agreement
     has been duly authorized by all requisite corporate action and, when fully
     executed and delivered will constitute the valid and binding agreement of
     NMT, enforceable in accordance with its terms except as enforcement may be
     limited by bankruptcy, insolvency, reorganization, moratorium or similar
     laws -affecting the enforcement of creditors' rights generally and rules or
     laws concerning equitable remedies.

     (ii) NMT is and shall at all times during the term of this Agreement be the
     principle owner of U.S. Patent 4,425,908, (the "Simon Patent"). NMT is not
     aware of any references which appear to invalidate the Simon Patent or of
     any patent which would appear to present an infringement problem for the
     Simon Patent, nor is NMT a party to any lawsuit or have any claims of
     infringement been asserted against NMT alleging in whole or in part that
     the Simon Patent or any other Proprietary Rights (as hereinafter defined)
     infringe any other proprietary or intellectual property rights anywhere in
     the Territory.

     (iii) All Products marketed by NMT have been accepted by the United States
     Food and Drug Administration ("FDA") by the procedure known as 510(k). NMT,
     to the best of its knowledge, has filed with the FDA all "MDR's" required
     to be filed pursuant to the United States Food and Drug Act, as amended,
     and the rules and regulations thereunder ("Act"). Any change, improvement
     or modification of any Product which could affect the safety or efficacy of
     any Product has been submitted to the FDA in form of 510(k) notification,
     and all such filings have been accepted by the FDA. The Product is being
     lawfully marketed in compliance with the Act and the rules and regulations
     of the FDA.

     (iv) NMT has legal right to the Product and can validly request
     distribution of the Product by Bard.

     (v) No product liability claim has been made or threatened against NMT.

     (vi) NMT is not currently a party to any agreement or understanding, oral
     or written, which would conflict with the rights herein granted to Bard.

     (b) Bard represents and warrants that Bard Radiology is a division of C. R.
Bard Inc., with full power and authority to enter into this Agreement, and that
this Agreement when duly executed and delivered will be a valid and binding
agreement of C. R. Bard Inc., enforceable

in accordance with its terms except as enforcement may be limited by bankruptcy,
insolvency, reorganization, moratorium or similar laws affecting the enforcement

Term or any Additional Renewal Term.

     (b) If Bard determines not to renew, NMT will accept returns from Bard of
Product XXXXXXXXXX, not to exceed the quantity purchased by Bard from NMT during
the six (6) months prior to the date of termination; and Bard will agree to
furnish NMT with customers list, list of sales to each customer, and other non-
confidential sales materials and marketing information.

     6. Price and Payment. NMT will sell Product to Bard at a price (the "Sales
        -----------------                                                      
Price") that is the XXXXXXXX of such XXXXXXXX to XXXXXXXX in effect in the
United States on the date of sale (the "SLP") XXXXXXXX, provided, that the Sales
                                                        --------

the Sales Price for those Products which in any 12 Month Period are purchased by
Bard and are in excess of 35% of the published IMS America for vena cava filters
for the immediately preceding 12 Month Period, shall be the SLP XXXXXXXX, and
the resulting decrease in SLP shall be credited to Bard's subsequent purchases

                                                CONFIDENTIAL TREATMENT REQUESTED
 
XXXXXXXX (the "Advance Payment"). The three installments of the Advance Payment

acceptance by Bard of the first order of the Product and upon the receipt and
acceptance by Bard of the second order of the Product, provided, however, that
if not earlier paid pursuant hereto the full payment shall be made by Bard on

herein the "12 Month Period" shall mean the twelve month period commencing on
the first day of the month in which Bard makes its first commercial sale of
Product anywhere in the Territory and ending on each twelve-month anniversary
thereof. If Bard fails to notify NMT in writing of the date of such first
commercial sale within ninety days of the date thereof, the date shall be deemed
to be 30 days after the date of this Agreement. NMT shall, until the Advance
Payment has been fully repaid, at Bard's option either credit Bard with XXXXXXXX

of the following specified minimums:

(i) XXXXXXXX during the second 12 Month Period;

(ii) XXXXXXXX during the third 12 Month Period;

(iii) XXXXXXXX during the fourth 12 Month Period;

(iv) XXXXXXXX during the fifth 12 Month Period and each 12 Month Period

In the event that the Advance Payment is not fully repaid on expiration,
nonrenewal or termination of this Agreement, NMT shall pay Bard XXXXXXXX per
month thereafter until the Advance Payment is fully amortized and repaid in
full.

     (b) During the Term of this Agreement if Bard's purchases of SNF's from NMT
fall below the following specified minimum purchases of SNFs for sale in the
United States, NMT as its sole and exclusive remedy shall be entitled to render
Bard's appointment hereunder non-exclusive and Bard shall be relieved of any
further Minimum Payments and the Sales Price shall be adjusted to be the greater
of (i) the XXXXXXXX or (ii) the XXXXXXXX as that XXXXXXXX in the XXXXXXXX that
XXXXXXXX and Bard shall not be liable to NMT or to any third party for any loss,
damage or claim arising out of Bard's failure to purchase the specified minimum
purchases. Any purchases above the specified minimum purchases in any 12 Month
period shall be credited to the minimum purchases for any other 12 Month Period.
Any such purchases applied to any other 12 Month Period for achieving Specified
Minimums shall be eligible only one time (at the actual time of purchase) for
computation of the amount of repayment of the Advance Payment due.

appointment non-exclusive shall become effective, NMT shall give written notice
of failure to meet the specified minimum provided in this section 7(b) and Bard
may, within 60 days thereafter, purchase enough SNF's to enable it to keep such
right to distribute Products in the Territory.

        (c) Specified minimums for any 12 Month Period may be reduced as
follows: (i) If there is a decline in any year in the IMS reported total Market
for vena cava filters then the Specified Minimum for such following 12 Month
Period shall be reduced by the same percentage as such decline; (ii) if sales by
Bard are adversely affected by (A) failure of NMT to deliver product as required
by this Agreement, (B) action of the FDA against NMT, (C) a competitive nitinol
vena cave filter being successfully marketed in the Territory, (D) any action by
a third party infringing the Proprietary Rights anywhere in the Territory or any
action brought against Bard alleging infringement of a third party's proprietary
or intellectual property rights by the Proprietary Rights or (E) any unusual and
dramatic adverse incident involving SNF, then the specified minimum for the
relevant 12 Month Period shall be reduced to the extent that such adverse events
have affected sales.  Bard shall, on or before the end of each 12 Month Period
advise NMT in writing stating its intention to reduce the specified minimum for
such 12 Month Period and specifying the cause of such reduction, the amount of
such reduction and any other relevant facts with respect thereto. If NMT
disagrees with the facts or the amount of such reduction, the parties shall
negotiate with respect thereto, and if they are unable to resolve said dispute
within thirty days, they shall submit the disagreement to arbitration in New
York in accordance with Section 23(1) hereof, with the added requirements that
the arbitration shall take place within 60 days after the end of the relevant 12
Month Period; that a single arbitrator shall be selected; that each party shall
be limited to a single space six-page affidavit; a double spaced six-page
written argument and a half-hour oral argument.

any and all infringers of patents owned by NMT for the Product. Bard shall not
be entitled to any damages, recovery or royalties resulting from any such legal
action conducted solely by NMT. However, Bard shall have the right to take legal
action at its own expense regarding infringements of such patents if NMT takes

                                      -9-
<PAGE>

        18. Inventions, Technical Information and Secrecy.
            --------------------------------------------- 

        (a) NMT shall advise Bard to the extent NMT has the right to do so of

technical information, inventions and/or suggested improvements of Bard relating

        (c) Any information furnished or disclosed by either party hereunder is

confidential information ("Confidential Information") will take such reasonable
action to the end that it shall not be disclosed to third parties except insofar
as such information:

        (i) was known to the receiving party prior to receipt from the
        disclosing party;

        (ii) is made public by the party providing the Confidential Information;

        (iii) is received in good faith by the receiving party from any third
        party;

        (iv) was or is or becomes part of the public domain or known to the
        trade otherwise than as a consequence of a breach of the obligation here
        undertaken not to disclose Confidential Information;

        (v) is disclosed as a matter of necessity by the sale of the Products.

        The obligation of confidentiality in this Section 18(c) shall continue

to interventional radiologists and desire to enter into an exclusive
distributorship in the United States, it shall disclose the relevant facts to
Bard. If Bard wishes to become the exclusive distributor of any such new device,
it shall so advise NMT in writing within ninety days after such disclosure. The
parties shall then negotiate for one month or such longer period as they may
agree, and, at the end of such period, Bard shall advise NMT in writing of its
best offer to distribute such new device. Failure to deliver such a letter to
NMT shall be deemed a

                                      -10-
<PAGE>
 
rejection by Bard.  Thereafter, NMT may negotiate for an exclusive
distributorship for such new device with any third party, but NMT may not enter
into a transaction with any third party for the distribution of such new device
on a basis less favorable to NMT than said best offer made by Bard. NMT has
begun negotiations with another company for a stent for the aorta, accordingly,
this section shall not apply to stents for the aorta.

        20. Force Majeure. Subject to the provisions of Section 22 hereof, in
            -------------                                                    
the event that the delay or failure of a party to comply with any obligation
created by this Agreement is caused by Force Majeure, that obligation shall be
suspended during the continuance of the Force Majeure condition. The term "Force
Majeure" shall mean any event beyond the reasonable control of the parties,
including, without limitation, fire, flood, riots, strikes, epidemics, war
(declared or undeclared) and embargoes.

        21. Default and Termination.
            ----------------------- 

        (a) If either party (the "defaulting party") shall refuse to comply with
any material provisions hereof, and if such default shall continue unremedied
for sixty days after written notice is given to the defaulting party by the
other party (the "other party") of such default, then the other party, after the
expiration of said sixty days and for so long as such default shall continue
unremedied, may elect at its option to terminate this Agreement by providing a
written termination notice to the defaulting party.

        (b) Voluntary or involuntary bankruptcy, receivership or insolvency
proceedings filed against either party (the "insolvent party") which are not
lifted within sixty days after filing will be valid ground for cancellation of
this Agreement by the other party. Such election may be made by notice in
writing to the insolvent party or its legal representatives.

        (c) Termination of this Agreement, however effected, shall not affect
any rights or obligations of the parties prior to the effective date of such
termination; provided, however, that after such expiration, termination or
surrender, NMT shall have the right to purchase at cost all Products owned by
Bard and, if NMT fails to do so, Bard and its Affiliates shall be entitled to
sell such Products anywhere in the Territory.

        22. License.

        (a) Agreement to Grant. NMT hereby acknowledges that a reliable and

                                Amendment No. 2

          This Amendment is made as of this 1st day of October 1995 to that
certain Agreement dated May 19, 1992 and amended on February 1, 1993 by and
between Nitinol Medical Technologies, Inc., a Delaware corporation ("NMT")
having its principal place of business at 175-P New Boston Street, Woburn, MA
01801 and C. R. Bard, Inc., a New Jersey corporation by its division, Bard
Radiology ("Bard"), which division has its principal office at 13183 Harland
Drive North East, Covington GA 30209.

1.     Advance Payments.  Section 7(a) of the Agreement is amended to read in 
                          ------------                 
full as follows:

       (a)    Pursuant to the Agreement Bard has made the Advance Payment in the
amount of XXXXXXXX to NMT.  As used herein, the "12-Month Period" shall mean the
twelve-month period which commenced on April 1, 1994  and ending on each twelve-
month period anniversary thereof.  To the date of this Amendment, NMT has at
Bard's option, either credited Bard with XXXXXXXX or paid Bard XXXXXXXX in cash
for each SNF purchase by Bard in excess of specified minimums.

The parties do hereby agree that from and after the date first above written NMT
shall, at Bard's option, either credit Bard with XXXXXXXX or pay Bard XXXXXXXX
in cash for each SNF purchased by Bard from NMT in excess of the purchase of Two
Thousand Five Hundred Thirty-Three (2,533) SNFs in the second 12-Month Period
and such credit or payment shall continue until the principal amount of the
Advance Payment shall have been repaid in full.  Bard shall not be obliged to
meet any further minimum purchases to obtain the credit or payment described in
this Amendment, and Subsections 7(a)(i) through (iv) of the Agreement are
                    -------------------         ----                     
expressly deleted.

Upon repayment of the principal amount of the Advance Payment, NMT shall pay to
Bard interest calculated as follows:  The amount of the Advance Payment
outstanding that exists at that point in the time when then principal amount
would have been repaid if done at XXXXXXXX multiplied by a fraction, the
numerator of which is the difference between the number of months beyond the
date the principal would have been repaid at XXXXXXXX and the actual number of
months to final repayment of principal at XXXXXXXX and the denominator of which
is 12 months; The product of this calculation shall be multiplied by XXXXXXXX
and the resulting total shall be paid by NMT to Bard within 30 days of the final
principal repayment.  For example, if the Advance Payment would have been repaid
by March 1996 at XXXXXXXX, but instead is repaid in January 1997 at XXXXXXXX,
and the principal balance at March 1996 is XXXXXXXX, then NMT would pay Bard
XXXXXXXX.

In the event that the Advance Payment is not fully repaid on expiration,
nonrenewal or termination of this Agreement, NMT shall pay Bard XXXXXXXX per
month thereafter until the Advance Payment is fully amortized and repaid in full
upon which date NMT shall pay the interest computed as above and each month in
which XXXXXXXX is paid shall count as an additional month in the numerator.

Agreement remain in full force and effect in accordance with their terms.

       IN WITNESS WHEREOF, the undersigned have hereunto set their hand and

                                                CONFIDENTIAL TREATMENT REQUESTED
 
     day of the first calendar quarter following such first Market Launch, the
     excess of (x) XXXXXXXXXX over (y) the weighted average Burdened Cost per
     Stent manufactured in the quarter, multiplied by the number of units of
     Stents manufactured by BSC and its Affiliates and sublicensees during the
     quarter; provided, however, that the first such payment shall also include
     VIP Payments calculated with respect to all Stents manufactured and placed
     in inventory for commercial sale during the period preceding Market Launch,
     and provided, further, that for this purpose, non-sterile Stents
     manufactured for demonstrations and Stents used for clinical trials and
     regulatory testing and evaluation and the Burdened Cost of these Stents
     shall be excluded from the calculation;

          (b) During the sixth through tenth years following the first day of
     the first calendar quarter following Market Launch of the first Product,
     the excess of (x) XXXXXXXXXX over (y) the weighted average Burdened Cost
     per Stent manufactured in the quarter, multiplied by the number of units of
     Stents manufactured by BSC and its Affiliates and sublicensees during the
     quarter (excluding, for this purpose, non-sterile Stents manufactured for
     demonstrations and Stents used for clinical trials and regulatory testing
     and evaluation); and

          (c) During the eleventh and each subsequent year following the first
     day of the first calendar quarter following Market Launch of the first
     Product, the excess of (x) the lesser of (i) XXXXXXXXXX times the
     XXXXXXXXXX, or (ii) XXXXXXXXXX over (y) the weighted average Burdened Cost
     per Stent manufactured in the quarter, multiplied by the number of units of
     Stents manufactured by BSC and its Affiliates and sublicensees during the
     quarter.

          The "Index" for eleventh and all subsequent years shall be defined by
     the following formula:

                    XXXXXXXXXX

     Where: I is the Index;

          XXXXXXXXXX is the XXXXXXXXXX for all XXXXXXXXXX for the United States
     as reported by the XXXXXXXXXX for January of the year in question;

          XXXXXXXXXX is the XXXXXXXXXX for all XXXXXXXXXX for the United States
     as reported by the XXXXXXXXXX for January of the tenth year of this

                            VI.  EXCLUSIVE LICENSE

          6.1  Grant of License.  If BSC notifies NMT of its intent to proceed
               ----------------                                               
to the license phase of this Agreement on or before October 31, 1994, NMT shall
and hereby does grant to BSC the sole and exclusive right, license and privilege
to use the License Rights in the Application Field, and to manufacture and sell,
and to grant sublicenses to others to use, manufacture and sell, Products in the
Territory.

          6.2  Licensing Fees.
               -------------- 

          (a) In consideration of the license granted above, for the longer of
     (x) twenty (20) years from Market Launch of the first Product or (y) until
     the expiration of the last patent which is part of the Patent Rights, BSC
     shall pay NMT with respect to Net Sales by BSC or its Affiliates to any
     third party (other than sales to Affiliates) of the Products, the following
     licensing fees:

               (i)  Except as set forth in Clause (iii), XXXXXXXXXX of Net Sales
          of Products that occur during the period beginning with Market Launch
          of the first Product and ending five (5) years after the first day of
          the first calendar quarter following such first Market Launch;

               (ii)  Except as set forth in clause (iii), XXXXXXXXXX of Net
          Sales of Products that occur during the term of this Agreement after
          the period set forth in clause (i);

               (iii)  In the event that any third party in any country markets
          an expandable nitinol Stent with welded cell design that competes with
          one or more Products marketed by BSC but which does not infringe the
          Patent Rights (such non-infringing competing product being hereinafter
          referred to as an "NIC Product"), then the BSC license fee for such
          Products will be reduced as hereinafter set forth: In each market for
          expandable nitinol Stents (e.g. biliary Stents , iliac Stents,
          peripheral vascular Stents, coronary Stents, urethral Stents, etc.) in
          which BSC can show that an NIC Product or NIC Products hold in the
          aggregate at least 10% of that market for expandable nitinol Stents,
          then the licensing fee provided in Section 6.2(a) (i) and 6.2 (a) (ii)
          for such Product in such market in such country shall be reduced from
          XXXXXXXXXX and XXXXXXXXXX, respectively, and the parties shall
          negotiate in good faith an appropriate reduction (even to zero, if
          appropriate) in the minimum licensing fee amounts in Section 6.5.

               If BSC believes it is entitled to pay a reduced licensing fee
          pursuant to this subsection, it shall so notify N~T in writing and the
          parties shall meet to resolve the matter.  If the parties do not
          agree, the

          matter shall be resolved pursuant to Sections 17.2 and 17.3.  BSC
          shall be entitled to pay the reduced licensing fee pending resolution
          of the dispute and shall pay the difference plus interest from the
          original due date at the rate set forth in Section 6.2(c) to NMT
          within thirty (30) days after resolution of the dispute if it is
          resolved in NMT's favor.

          (b) (i)  Where the components of a Product or Product Combination are
     not each generally sold as separate units, the computation of Net Sales
     shall be based on the relative contribution of the components of the
     Product or Product Combination.  Relative contribution shall reflect the
     relative complexity and importance to end-users of the various separate
     components of the Product or Product Combination, and shall be negotiated
     in good faith from time to time by the parties.  NMT and BSC agree that the
     relative contribution of a Stent to a Product shall not, in any case, be
     less than XXXXXXXXXX of Net Sales (except in the case of Products for
     abdominal aortal aneurysms, for which the contribution of the Stent may be
     determined to be less than XXXXXXXXXX), and shall be XXXXXXXXXX of Net
     Sales when sold as a Product with a nitinol Stent substantially similar to
     the present design and a catheter-based delivery system incorporating art
     substantially similar to that which is presently generally known in the
     industry.  Any dispute arising under this Section 6.2(b) will be resolved
     pursuant to Sections 17.2 and 17.3 hereof.

               (ii)  Subject to the application of clause (i) to the Product
          components of a Product Combination, in order to determine the Net
          Sales of the Stent included therein, where the components of a Product
          Combination are each generally sold as separate units, the computation
          of Net Sales of the Product portion of the Product Combination shall
          be determined by multiplying the Net Sales of the Product Combination
          by the fraction A/(A + B), where A is the average selling price during
          the prior calendar year of the Product which is part of the Product
          Combination and B is the average selling price during the prior
          calendar year of the other components of the Product Combination.

               (iii) If NMT has developed any component of the Product or
          Product Combination other than the Stent component thereof (for
          example, a delivery system), the relative contribution of (and the
          corresponding percentage of Net Sales attributable to) NMT components,
          including the Stent, shall increase (e.g., from XXXXXXXXXX) in
          calculations under clause 6.2(b) (i) above and any NMT component which
          is not part of the Product portion of a Product Combination shall be
          included in the "A" portion of the formula in clause 6.2(b) (ii)
          above.

               (iv)  In determining the relative contribution of the components
          of a Product or Product Combination, consideration shall be given to
          any third party payments required.

          (c) Except as set forth in Section 6.5(a), the fees payable under
     paragraph (a) shall be paid within sixty (60) days after the close of each
     calendar quarter during the term of this Agreement, and simultaneously
     therewith BSC shall furnish to NMT a statement showing on a US/OUS basis
     and in the aggregate for those countries in which a different licensing fee
     is payable pursuant to Section 6.2(a)(iii), the Net Sales and unit sales of
     BSC and its Affiliates and sublicensees subject to licensing fees and the
     licensing fees due with respect to that calendar quarter, all calculated in
     reasonable detail.  Late payments shall bear interest at a rate equal to
     XXXXXXXXXX the XXXXXXXXXX of the XXXXXXXXXX.  BSC's obligations to NMT with
     respect to sales from a sublicensee or subdistributor shall arise in the
     calendar quarter in which such sales are recognized by BSC in its financial
     statements.

          (d) Except as otherwise provided herein, the payments to be made to
     NMT under this Agreement are the actual amounts to be received by NMT and
     shall not be reduced in any way, including but not limited to, by any
     liabilities incurred by BSC or its Affiliates or sublicensees upon
     remittance to NMT of the payments due hereunder.  In the event BSC or its
     Affiliates or sublicensees are required to make a deduction or withholding
     of tax, in those situations in which it is possible for BSC to receive the
     benefit of the withholding or deduction in any way (by use to offset U.S.
     or foreign tax, by refund or otherwise) then the amount payable to NMT
     shall be increased to the extent necessary to ensure that after the making
     of such deduction or withholding, NMT receives and retains an amount equal
     to that which it would have received or retained had no such deduction or
     withholding been made by BSC or its Affiliates or sublicensees.  In such
     case, NMT shall assign to BSC its right to recover such deduction or
     withholding from the relevant government authorities.  Each party agrees to
     assist the other by submitting declarations to the relevant authorities as
     may be required with regard to each party's status in relation to a
     deduction or withholding of taxes.

          (e) To the extent licensing fees have been paid on non-patented
     Products or on Products for which all applicable patents have expired or
     held invalid, BSC shall have the perpetual royalty-free non-exclusive right
     to manufacture, use and sell such Products after the period set forth in
     Section 6.2(a) that shall survive termination of this Agreement at the end
     of the term set forth in Section 8.1.

          (f) All payments required to be made under this Agreement shall be
     made in U.S. dollars.  Monetary conversions from the currency of a foreign
     country into U.S. dollars shall be made in the manner that BSC generally
     applies for translation of fees payable to third parties, applied in a
     consistent manner, or on another basis mutually agreed upon by both parties
     in writing, provided that any conversion rate used does not distort the
     payments required under this Agreement and that the total licensing fees
     for each year shall agree with the amount reported in the financial
     statements of BSC for that year.

     6.3  Additional Payments.
          ------------------- 

          (a) Upon written notice to NMT on or before October 31, 1994, or such
     later date as the parties may agree, of its election to exercise its rights
     to take the license granted herein, BSC shall pay to NMT a non-refundable
     (except as provided in Section 6.3(c)) lump sum fee in the amount of
     XXXXXXXXXX in consideration of the grants and the exclusive nature thereof
     as set forth in this Agreement.

          (b) If BSC has properly elected to exercise its rights to take the
     License granted herein, upon the issuance of a valid United States patent
     with claims covering any of the Product Developments or Technical
     Information or the Products (or, if such patent is issued prior to such
     exercise, then on October 31, 1994, or such later date as the parties may
     agree), BSC shall pay to NMT a nonrefundable fee in the amount of
     XXXXXXXXXX.

          (c) In the event a third party United States patent, reissuance,
     extension, division, or continuation issues covering the Products within
     three (3) months of BSC's written exercise of its rights to take the
     license granted herein, BSC may terminate this Agreement.  If BSC so
     terminates this Agreement, NMT shall refund XXXXXXXXXX of the additional
     payments set forth in this Section 6.3 upon written request of BSC.

          (d) In the event a third party patent, reissuance, extension,
     division, or continuation issues covering Products during the period of
     twenty-one (21) months following the period set forth in Section 6.3(c),
     which prevents BSC in the entire Territory from reasonably entering the
     market or, once entered, reasonably continuing in the market, with Stents
     made, used and sold pursuant to the Patent Rights included in the License
     Rights, and BSC as a result thereof terminates this Agreement, NMT shall
     refund XXXXXXXXXX of the payments made to NMT pursuant to this Section 6.3
     and Section 6.4.  If, during said twenty-one month period, BSC is prevented
     from making, using and selling Stents as aforesaid in a part, but not all
     of the Territory, the parties shall negotiate as to how much, if any, of
     such payments under Section 6.3 and

     Section 6.4 shall be repaid by NMT to BSC, and, if the parties do not
     agree, the matter shall be resolved pursuant to Section 17.2 and Section
     17.3.

          (e) In the event a third party patent, reissue, extension, division or
     continuation issues covering the Products, then (i) the parties shall
     negotiate in good faith an appropriate reduction in the minimum licensing
     fee amounts in Section 6.5 (which may reduce minimum licensing fee amounts
     to zero, if appropriate), and (ii) the deadlines for the milestone payments
     based on Market Launches for the affected Products in the regions (United
     States or major OUS markets in which BSC has a direct marketing presence)
     in which such third party patent issues shall be suspended, but such
     milestone payments, in the amounts set forth in Section 6.4 or such other
     amounts as the parties may agree upon in good faith, shall continue to be
     payable in the event of subsequent Market Launches.

     6.4  Milestone Payments.  In addition, BSC shall pay NMT the following non-

                    (viii)  United States Market Launch of coated vascular
          Product, but in no event later than January 1, 1998, XXXXXXXXXX;

     provided, however, that if BSC is prevented from achieving any of the dates
     --------                                                                   
     set forth in clauses (iii) through (viii) by regulatory authorities despite
     BSC's diligent efforts to obtain necessary regulatory approvals, the time
     for the payments required by such clauses will be extended until necessary
     regulatory approvals are obtained; and provided, further, that if BSC
                                            --------  -------             
     supplies commercial quantities of Stents for US and OUS sale from a single
     facility for a period of twelve [12] months, then the payment required by
     the remaining of clauses (i) and (ii) shall be paid at the end of said
     twelve-month period.  Payments under each of the subsections in this
     Section 6.4 shall be independent of payments due under the other
     subsections.

     6.5  Minimum Net Sales.
          ----------------- 

          (a) If licensing fees pursuant to Section 6.2 are less than the
     amounts set forth in the table below, BSC shall have the right to retain
     exclusivity by paying to NMT, with the licensing fee statement for the
     fourth quarter, an amount which would bring the licensing fees for the year
     up to the amount set forth in the table below.  If BSC does not make such
     payment NMT shall have the right upon thirty (30) days prior written notice
     to BSC to make the exclusive license granted hereunder nonexclusive;
     provided, however, that BSC shall have the right to retain exclusivity by
     --------                                                                 
     paying to NMT during such thirty (30) day period an amount which would
     bring NMT's Licensing Fee up to the amount set forth in the table below.
     All amounts paid by BSC to retain exclusivity as set forth above may be
     applied against future Licensing Fees payable by BSC to NMT in years when
     licensing fees to NMT exceed the herein stated minimums.  The amounts for
     years 1995 and thereafter are:
 
                    Year                   Minimum Licensing Fee Amount
                    ----                   ----------------------------
                    1995                            XXXXXXXXXX

          (b) For calendar year 1996, BSC shall pay to NMT the applicable
     minimum licensing fee in quarterly payments in the amount of XXXXXXXXXX per
     quarter.  BSC shall submit such minimum licensing fee payments to NMT on or
     before January 1, April 1, July 1 and October 1 of such year.  To the
     extent the licensing fee due and owing under Section 6.2(a) for a quarter
     during 1996 shall exceed the amount of such minimum licensing fee payment
     which has been paid for the quarter,

                                                CONFIDENTIAL TREATMENT REQUESTED
 
     BSC shall pay such excess within sixty (60) days after the end of such
     quarter.  To the extent that the amount of the licensing fee due and owing
     for a quarter during 1996 shall be less than the amount of such minimum
     licensing fee payment paid for the quarter, then the difference between
     these two amounts shall be credited against any additional licensing fee
     payments which may be owed with respect to any other quarter of the year or
     any subsequent years.

     6.6  Diligence.  BSC shall use diligent efforts in a commercially
          ---------                                                   
reasonable manner to develop Products, obtain regulatory approval for the sale
of Products, and market and sell Products.

     6.7  Payments from Sublicensees.  BSC shall pay to NMT XXXXXXXXXX of all
          --------------------------                                         
royalties, license fees, milestone payments and other sums received from
sublicensees of the License Rights within sixty (60) days after receipt thereof
by BSC.

                                 VII.  RECORDS

     7.1  Records.
          ------- 

          (a) BSC and its Affiliates shall keep, and BSC shall use its
     reasonable best efforts to cause its sublicensees to keep, accurate records
     of Net Sales in sufficient detail to support the license fees paid to NMT
     and of Burdened Costs in sufficient detail to support the VIP Sharing
     described in Section 5.3.  For each year during the term of this Agreement
     and for three (3) years after such year, NMT and its authorized agents,
     representatives, counsel and accountants shall have the right from time to
     time (but not more than once annually) during regular business hours to
     audit licensing fees and VIP Payments paid for such year and to examine,
     abstract and copy such records, and all workpapers and background material
     from which such records have been derived, for the sole purpose of
     confirming and verifying such amounts.  The cost of such audit shall be
     borne by NMT unless it shall be established by the audit that BSC has
     underpaid NMT by at least XXXXXXXXXX for the period audited, in which event
     the reasonable cost of such services will be borne by BSC.

          (b) If requested by NMT, BSC will provide NMT with a self conducted
     audit, in detail as requested by NMT, of all accountings for VIP and
     license fees and other related matters, at BSC's cost and expense.  NMT may
     request this not more than once every three (3) years.

          (c) NMT shall keep accurate records of Development Cost in sufficient
     detail to support costs charged to BSC.  BSC and its authorized agents,
     representatives, counsel and accountants shall have the right from time to
     time during regular business hours to audit Development Costs and to

     examine, abstract and copy such records, and all workpapers and background
     material from which such records have been derived, for the sole purpose of
     confirming and verifying Development Costs.  The cost of such audit shall
     be borne by BSC unless it shall be established by the audit that BSC has
     overpaid NMT by at least XXXXXXXXXX for the period audited, in which event
     the reasonable cost of such services will be borne by NMT.

                          VIII.  TERM AND TERMINATION

     8.1  Effective Date and Term.  This Agreement shall become effective as of
          -----------------------                                              
the date first above written, and shall remain in full force and effect until
the expiration date of the last remaining patent included in the Patent Rights,
but not less than twenty (20) years after Market Launch of the first Product.

     8.2  Termination.  Notwithstanding Section 8.1 hereof, this Agreement may
          -----------                                                         
be terminated upon delivery of written notice in reasonable detail:

          (a) By either party, if the other shall fail in any respect to observe
     or perform any of the material provisions of this Agreement on its part to
     be observed or performed, and any such failure shall not be remedied within
     sixty (60) calendar days or, in the case of payments due, within thirty
     (30) calendar days after receipt of written or telecopied notice from the
     other party specifying such failure;

          (b) By either party, if the other shall become insolvent or a receiver
     shall be appointed for its business or properties, or if any petition shall
     be filed by or against it under any provisions of any bankruptcy,
     insolvency or similar laws, if such petition or proceeding is not dismissed
     with prejudice within sixty (60) days after filing;

          (c) By either party if BSC fails to deliver written notice of exercise

          ---------------------                                             
without prejudice as to any right of either party hereto with respect to any
obligation of the other party accrued on or prior to the effective date of such
termination.  Upon termination, BSC shall have no further rights hereunder.  If
termination is effected by NMT pursuant to Section 8.2(a), then NMT and BSC
shall negotiate in good faith a royalty to be paid by NMT to BSC in the event
NMT shall thereafter sell any Stents incorporating the License Rights which
incorporate technology of BSC, such royalty to fairly reflect the relative value
of the BSC technology in such Stents.  BSC may incorporate Stents held in
inventory into Products and sell the same in the ordinary course of business,
subject to licensing fee payments hereunder, during the six (6) months following
termination.  If termination takes

costs incurred or committed by NMT in winding down the Development Program in an
amount (which must be within the budget, subject to the XXXXXXXXXX allowance
permitted by Section 3.1) not to exceed XXXXXXXXXX, including the salaries of
personnel involved therein for the two (2) months following termination.

                          INDEMNIFICATION, INSURANCE
                     PATENT INDEMNITY, PATENT ENFORCEMENT

     10.1 Patent Applications and Foreign Filing.  NMT shall have the right but
          --------------------------------------                               
not the duty to file, prosecute, and maintain in force, at NMT's expense, any
and all patents and applications for patents covering inventions developed or
acquired by or for NMT falling within the Patent Rights, using patent attorneys
designated by NMT.  NMT shall keep BSC reasonably informed of patent prosecution
and maintenance activities involving the Patent Rights, but NMT shall have no
liability to BSC with regard to NMT's activities under this paragraph.  All such
patent applications shall be filed, prosecuted and maintained in the name of NMT
or such other applicant designated by NMT who agrees to become bound by this
Agreement.  In the event NMT at any time elects not to file, prosecute or
maintain in force any patent or patent application falling within the Patent
Rights, BSC shall have the right, at its sole expense, to do so.

     10.2 Adverse Rights of Others.  In the event that the manufacture, use, or
          ------------------------                                             
sale by BSC of nitinol Stents included in any Products is objected to as
infringing a patent held by another party, BSC shall so notify NMT and the
parties shall discuss the appropriate response.  From the earliest date on which
(i) BSC reasonably believes, based on the advice of counsel, that a significant
question of infringement of a patent owned by a third party exists, or (ii) BSC
receives any notice deemed legitimate by BSC, with the advice of counsel,
alleging such infringement, or (iii) any suit is filed against BSC by the party
making such objection, until the objection is resolved in a manner which permits
BSC to sell such Products without payment to the third party, (i) BSC shall have
the right to retain as a reserve XXXXXXXXXX of any licensing fees coming due to
NMT under Article 6, and to apply such reserve against half of: (a) of its legal
expense in such suit, (b) any settlement cost or license fee, and (c) any court
ordered recovery; and (ii) the deadlines for the milestone payments based upon
Market Launches for the affected Products in the regions (United States or major
OUS markets in which BSC has a direct marketing presence) in which such notice
or suit is pending shall be suspended (but such milestone payments, in the
amounts set forth in Section 6.4 or such other amounts as the parties may agree
upon in good faith, shall continue to be payable in the event of subsequent
Market Launches), and the parties shall negotiate in good faith an appropriate
reduction in the minimum licensing fee amounts in Section 6.5.  Upon final

resolution of all such matters, BSC will pay any balance of said reserve to NMT.
BSC shall have the right to control the defense of any such claim and shall bear
the costs thereof, and shall keep NMT fully informed at all times.  NMT shall
cooperate fully with BSC in the defense of any such claim and shall be
reimbursed by BSC for its out-of-pocket expenditures incurred in such
cooperation.  BSC shall have the absolute right to resolve the matter in any way
it deems commercially reasonable, including, without limitation, by granting a
license to the third party of the License Rights or by cross licensing
technology.  In the event the resolution of the matter requires BSC to make
royalty or other payments to the other party, then, (x) if the third party
patent in question was issued prior to the date of this Agreement, BSC may
retain up to XXXXXXXXXX of any future licensing fee due to NMT under this
Agreement to meet up to XXXXXXXXXX of royalty or other payments payable by BSC
to the third party, and (y) if the third party patent in question was issued
after the date of this Agreement, BSC may subtract royalty or other payments
from the amount of licensing fees due to NMT pursuant to the relevant provisions
of Section 6.2 hereof, provided that the licensing fees payable by BSC to NMT
pursuant to the relevant provisions of Section 6.2 shall not be reduced to less
than XXXXXXXXXX of Net Sales of Products, Net Sales having been determined in
accordance with the relative contribution rules in Section 6.2(b).  Any royalty
or other payment payable by BSC to the other party under any settlement shall be
commercially reasonable to resolve the matter.  If BSC shall enter into any
settlement or agreement requiring any such royalties or other payments to the
other party, and if NMT believes the royalties or other payments to the other
party are not commercially reasonable, then NMT shall so notify BSC and the
matter shall be resolved in accordance with Article XVII hereof, and only
commercially reasonable royalties and other payments, as determined in
accordance with Article XVII, shall be subject to being retained or subtracted
pursuant to this Section and any excess previously retained or subtracted shall
be paid to NMT.

     10.3 Third Party Infringement.
          ------------------------ 

          (a) In the event any of the Patent Rights shall be infringed by a
     third party in the Application Field and BSC notifies NMT of the facts
     concerning the infringement, NMT may, but shall not be obligated to,
     institute and prosecute, at its own expense, any action in the name of NMT
     necessary to protect the rights of BSC and NMT under this Agreement.  In
     such event, NMT shall retain out of any monies collected through such
     action its expenses, shall reimburse BSC for its contribution to expenses
     under paragraph (b) below, and shall retain XXXXXXXXXX of the balance, the
     remainder to be paid to BSC.  In any such action, BSC shall fully cooperate
     with NMT and, at its own expense, be entitled to non-controlling
     participation through counsel of its own selection.

          (b) During the pendency of any prosecution of such action by NMT, BSC
     shall contribute to the expenses of such action, XXXXXXXXXX of the cost
     thereof.

          (c) In the event NMT elects not to institute and prosecute any such
     action, BSC may, but shall not be obligated to, prosecute any action, at
     BSC's own expense, in NMT's name for BSC's benefit.  In such action, NMT
     shall fully cooperate with BSC and, at its own expense, be entitled to non-
     controlling participation through counsel of its own selection, but shall
     be entitled to reimbursement of such expense out of XXXXXXXXXX of any
     monies collected through such action.

          (d) For so long as (i) the alleged infringing product is marketed by
     the third party, and (ii) such alleged infringing product, together with
     all relevant NIC Products, hold in the aggregate at least 10% of the
     relevant market for expandable nitinol Stents (determined as set forth in
     Section 6.2(a)(iii), the deadlines for the milestone payments based on
     Market Launches of the affected Products in the regions (United States or
     major OUS markets in which BSC has a direct marketing presence) in which
     such alleged third party infringing product is sold shall be suspended, and
     such alleged third party infringing product shall be treated as an NIC
     Product for all purposes of Section 6.2(a)(iii).

     10.4 Patent Legend.  All Products sold hereunder, or Product labels or
          -------------                                                    
written documentation commonly distributed with Products sold, shall be marked
in the reasonable discretion of BSC with words substantially similar to the
following or other appropriate patent legend: "This product is protected by U.S.
Patents Nos. [list of applicable patent numbers] and foreign counterparts, with
others pending."

     10.5 Trademarks.  BSC shall have the right to market and advertise Products
          ----------                                                            
in the Application Field in the Territory exclusively (except as provided herein
or as otherwise expressly agreed to in writing by the parties) under BSC's name,
trademarks, tradenames, labels or other designations, and all of the same shall
remain property of BSC and NMT shall have no rights thereto.  BSC shall have no
right, title or interest in NMT's trademarks.

     10.6 Indemnification.  BSC shall indemnify, defend and hold harmless NMT
          ---------------                                                    
and its directors, officers, employees, and agents and their respective
successors, heirs and assigns (the "Indemnities"), against any liability,
damage, loss or expense (including reasonable attorneys' fees and expenses of
litigation) incurred by or imposed upon the Indemnities, or any one of them, in
connection with any claims, suits, actions, demands or judgments (a) arising out
of the production, manufacture, sale, use in commerce, lease, or promotion by
BSC or by an Affiliate, sublicensee, distributor or agent of BSC, of any
Product; provided, however, that BSC's indemnification under this Section

                                      -21-
<PAGE>
 
10.6 shall not apply to any liability, damage, loss or expense in the event that
NMT withheld from BSC information which would have been relevant to the
determination of the safety of the Product in question and such action was a
proximate cause of the claim, suit, action, demand or judgment in question.

     10.7 Insurance.  At such time as any Product is being commercially
          ---------                                                    
distributed or sold by BSC or by an Affiliate, sublicensee, distributor or agent
of BSC, BSC shall, at its sole cost and expense, procure and maintain policies
of comprehensive general liability insurance in amounts not less than $5,000,000
per incident and $5,000,000 annual aggregate and naming the Indemnities as
additional insureds.  Such comprehensive general liability insurance shall
provide (a) product liability coverage and (b) broad form contractual liability
coverage for BSC's indemnification under Section 10.6 of this Agreement.  The
minimum amounts of insurance coverage required under these provisions shall not
be construed to create a limit of BSC's liability with respect to its
indemnification obligation under Section 10.6 of this Agreement.  BSC shall
provide NMT with written evidence of such insurance upon request of NMT.  BSC
shall provide NMT with written notice at least fifteen (15) days prior to the
cancellation, non-renewal or material change in such insurance; if BSC does not
obtain replacement insurance providing comparable coverage within such fifteen
(15) day period, NMT shall have the right to terminate this Agreement effective
at the end of such fifteen (15) day period without any notice or additional
waiting periods.  BSC shall maintain such comprehensive general liability
insurance beyond the expiration or termination of this Agreement during (a) the
period that any Product is being commercially distributed or sold by BSC or by a
sublicensee, Affiliate, distributor or agent of BSC and (b) a reasonable period
after the period referred to in clause (a) above, which in no event shall be
less than five (5) years.

     10.8 Notice and Assumption of Defense.  In the event any action is
          --------------------------------                             
commenced or claim made or threatened against NMT or other Indemnities as to
which BSC is obligated to indemnify it (them) or hold it (them) harmless, NMT or
the other Indemnities shall promptly notify BSC of such event.  BSC agrees, at
its own expense, to provide attorneys reasonably acceptable to NMT to defend
against any actions brought or filed against any party indemnified hereunder
with respect to the subject of indemnity contained herein, whether or not such
actions are rightfully brought.  BSC shall assume the defense of, and may
settle, that part of any such claim or action commenced or made against NMT (or
other Indemnities) which relates to BSC's indemnification and BSC may take such
other steps as may be necessary to protect itself.  NMT and the Indemnities
shall cooperate fully in the defense of such claim or action, at BSC's expense,
and may participate in the defense thereof through their own counsel, but at
their own expense.  BSC shall not be liable to NMT or other Indemnities on
account of any settlement of any such claim or litigation affected without BSC's
consent.  The right to BSC to assume the defense of

                                      -22-
<PAGE>
 
                                                CONFIDENTIAL TREATMENT REQUESTED
 
any action shall be limited to that part of the action commenced against NMT
and/or Indemnities which relates to BSC's obligation of indemnification.

     10.9  Notice of Injuries.  BSC shall give NMT notice of any claim of injury
           ------------------                                                   
or adverse effect related to any Stent incorporating License Rights reasonably
promptly after BSC becomes aware thereof.

     10.10  Survival.  Sections 10.6 through 10.9 shall survive termination or
            --------                                                          
expiration of this Agreement.

     10.11  Interferences.  At any time BSC becomes aware of a potentially
            -------------                                                 
interfering patent or patent application held by a third party which in BSC's
reasonable opinion may impact adversely its ability to sell Products in the
United States, BSC may initiate in the name of NMT or BSC an interference
proceeding, respond to a third party interference action on behalf of NMT or
BSC, or compromise the potential interference.  To the extent BSC becomes
obligated by settlement or court order to pay royalties or other amounts to such
third party, BSC may subtract such amounts from the amount of licensing fees BSC
is required to pay NMT pursuant to the relevant provisions of Section 6.2
hereof, provided, however, the license fees payable by BSC to NMT pursuant to
        --------                                                             
the relevant provisions of Section 6.2 shall not be reduced to less than
XXXXXXXXXX of Net Sales of Products in the United States, Net Sales having been
determined in accordance with the relative contribution rules in Section 6.2(b);
provided, further, that if BSC shall enter into any settlement or agreement
requiring any such royalties or other payments to the other party without the
consent of NMT, which consent shall not be unreasonably withheld, then BSC may
not subtract such amounts from any such future licensing fees due to NMT.  The
parties shall bear the expense of any such interference proceeding equally.  BSC
shall be entitled to select patent counsel, reasonably acceptable to NMT, to
represent NMT and BSC in any interference proceeding.  Such counsel shall act at
the direction of BSC, subject to the requirement that NMT participate in and
consent in writing, which consent shall not be unreasonably withheld or delayed,
to all significant decisions related to the proceeding.


                         XI.  CONFIDENTIAL INFORMATION

     11.1 It is contemplated that in the course of the performance of this
Agreement each party may, from time to time, disclose Confidential Information
to the other.  Each party agrees to make diligent efforts to prevent disclosure
of Confidential Information.  Efforts to prevent disclosure shall not be less
than those taken by each party to protect their own proprietary information.
Notwithstanding the foregoing, no provision of this Agreement shall be construed
so as to preclude such disclosure of Confidential Information as may be inherent
in or reasonably necessary for securing from any governmental agency any
necessary

                                      -23-

commercially reasonable efforts to obtain appropriate protective orders or other
reasonable assurances of confidentiality.  Each party agrees that Confidential
Information shall be used solely for purposes of this Agreement and shall be
disclosed or disseminated only to employees and agents who have a "need to know"
to carry into effect the terms and purposes of this Agreement.


                              XII. FORCE MAJEURE

     12.1 Any delay in the performance of any of the duties or obligations of
either party hereto shall not be considered a breach of this Agreement and the
time required for performance shall be extended for a period equal to the period
of such delay; provided that such delay has been caused by or is the result of
               --------                                                       
any acts of God, acts of the public enemy, insurrections, riots, embargoes,
labor disputes, including strikes, lockouts, job actions, or boycotts, fires,
explosions, floods, shortages of material or energy or other unforeseeable
causes beyond the control and without the fault or negligence of the party so
affected and provided further that payment obligations cannot be extended for
             -------- --------                                               
more than thirty (30) days.  The party so affected shall give prompt notice to
the other party of such cause, and shall take whatever reasonable steps are
necessary to relieve the effect of such cause as rapidly as possible.

     1.   Documentation of SNF Non-filter Components.  Lake Region has made a
          ------------------------------------------                         
complete itemized breakdown of the drawings, standard operation procedures
(SOP's), routers, templates, and fixturing for all of the non-filter components
of the SNF systems: Original, Modified and Simplified, which have been, or are
in the process of being, manufactured by Lake Region and sold to NMT pursuant to
that Manufacturing Agreement of June 30, 1988, as amended and extended (which
Agreement expired June 30, 1995) or which will be manufactured pursuant to this
Agreement.

     The parties have agreed that Lake Region would prepare such documentation
to submit to NMT for reimbursement. NMT will pay to Lake Region XXXXXXXX for
such documentation in three equal payments as follows:

          XXXXXXXX on the Effective Date;
          XXXXXXXX three (3) months after the Effective Date; and
          XXXXXXXX six (6) months after the Effective Date.

     Lake Region will deliver to NMT on the Effective Date the plans, drawings,
specifications, SOP's, and everything else comprising the complete documentation
developed by Lake Region for all non-filter components, as set forth in Exhibit
A.

     2.   Modified SNF System.  Lake Region has completed the "Modified" SNF
          -------------------                                               
system and will discontinue the manufacture of such system for NMT by June 30,
1996, or sooner as agreed between the parties. The prices for the Modified
System are set forth in Exhibit B.

     3.   Simplified SNF System.  The "Simplified" system was completed and
          ---------------------                                            
implemented by Lake Region, and accepted by NMT, by November 1, 1995. Lake
Region will discontinue the manufacture of the Simplified system and packaging
of the non-filter components by June 30, 1996, or sooner as agreed between the
parties. The prices for the Simplified System are set forth in Exhibit C. NMT
will also pay, on net 30 terms, for all required Lake Region engineering support
at a rate of XXXXXXXX per hour, to be verified by Lake Region as to individual
engineer, the timing of the work and the subject matter of the project when
billed to NMT.

     4.   Manufacturing Requirements/Pricing. Lake Region will manufacture for
          ----------------------------------                                  
NMT, and NMT will purchase from Lake Region, a minimum of seventy-five (75%)
percent of NMT's requirements for the Product for NMT sale and distribution both
to U.S. and non-U.S. markets for a five (5) year term (the "Term") starting July
1, 1996 and ending June 30, 2001.  Lake Region's price to NMT for the Product is
set forth in Exhibit D.  Such price is "firm" for the first year of the Term
with any price increases or decreases thereafter to be determined by the
increase or decrease in the XXXXXXXX published by the XXXXXXXX as set forth in
Appendix 1. Lake Region will advise NMT, in writing, at least thirty (30) days
in advance of any price increase or decrease and the basis for such change.

     NMT agrees to place blanket Purchase Orders and submit forecasts as
follows:

                                     - 2 -
<PAGE>
 
     (a) Not less than forty-five (45) days prior to the last day of each
Quarter (as hereinafter defined) during the Term, NMT will provide to Lake
Region a Purchase Order in the form described in Subsection (b) hereof with
respect to the purchase of all the Products to be shipped to NMT during the
following Quarter and a non-binding rolling forecast of the number of units of
Product to be delivered to NMT pursuant hereto during the three (3) immediately
following Quarters. NMT will, on or before June 1, 1996, submit a Purchase Order
for the first Quarter of the Term and the forecast for the three (3) Quarters
immediately following.

     (b) NMT's Purchase Orders will contain the following information:

          (1)  reference to this Agreement;

          (2)  a description of each Product ordered including the model number;

          (3)  the quantity of each Product ordered;

          (4)  the requested delivery dates for each Product;

          (5)  the per unit purchase price as determined in accordance with this
               Agreement; and

          (6)  shipping instructions.

     (c) Neither NMT's nor any Assignee's Purchase Orders will contain any terms
or conditions which are inconsistent with or contradictory to the terms and
conditions of this Agreement or which impose any materially different or
additional duties and obligations upon Lake Region.

     (d) Lake Region will be obligated to accept any Purchase Order for the
Products submitted by NMT hereunder and which conforms to the following terms
and conditions:

          (1)  Lake Region will maintain the production capacity required to
               fulfill NMT's unit requirements for quantity increases not to
               exceed 25% of one-fourth of the annual minimum purchase
               commitment (set forth in Section 6).

          (2)  Unit requirements in excess of 25% of one-fourth of the annual
               minimum purchase commitment (set forth in Section 6) will require
               six (6) months written notice and purchase commitment and will
               necessitate Lake Region's analysis of capacity expansion
               opportunities available to meet such request.  Lake Region will
               complete its analysis and notify NMT of the results and its
               decision within thirty (30) days of NMT's request. Agreement of
               the parties to proceed with the increased unit volume will result
               in an increase of NMT's annual minimum purchase commitment.

                                     - 3 -
<PAGE>
 
               The adjusted annual minimum purchase commitment for the
               immediately following twenty-four (24) months of the Term will be
               ninety percent (90%) of the new annualized quantity.

     Despite any increase of NMT's annual minimum purchase commitment, as set
forth above, the minimum unit quantities set forth in Section 6 on the Effective
Date will continue to be the baseline for computation of any additional unit
quantity increases pursuant to this Subsection 4.(d) during the Term.*

     *Example: Assume NMT elects to increase the third quarter of the first year
               purchases by orders of 25% (i.e., 437 units plus 1,750 units
               equals 2,187 units). If, for the second quarter of the second
               year, it wishes to increase its orders in excess of 25%, the
               baseline for such increase is 1,925 units.


     Despite these limitations on the contractual right of NMT to increase the
minimum unit quantities, Lake Region will use its reasonable best efforts to
satisfy NMT's requests for increased quantities.

     Notification periods are measured from the date of NMT written notice and
purchase commitment to the agreed to date of shipment.

     Lake Region will not be required to ship any quantity in excess of these
guidelines without such required written notice and purchase commitment from
NMT.  Lake Region and NMT may negotiate a shorter lead-time in the event of
change in NMT's forecast. However, such negotiated shorter lead-time will only
require Lake Region's reasonable best efforts to meet such requirements and will
not be a breach of this Agreement if Lake Region fails to meet such shorter
delivery schedules. Additionally, NMT will reimburse Lake Region for the
reasonable incremental cost of delivery for any such additional Products due to
overtime, expediting receipt of material and similar items, provided that the
parties have previously agreed to the amount of such incremental cost.

     (e) NMT agrees to purchase all inventory and all work in process in the
event of order cancellation or conversion by NMT to another Product item. In the
event change orders are issued requesting delayed delivery, NMT agrees to
purchase such inventory within six (6) months from the date of such change
order.

     (f) Lake Region is to notify NMT, in writing, of any delay beyond five (5)
working days in scheduled delivery, including in the notification a best
estimate as to revised delivery date(s).

     5.   Manufacturing Schedule. Lake Region will manufacture and sell, and NMT
          ----------------------                                                
will buy, the following SNF filter products in accordance with the following
schedule and prices.

     6.   Minimum Purchases. In addition to the obligation that NMT purchase at
          -----------------                               
least Seventy-five (75%) percent of its Product requirement from Lake Region as
set forth in Section 4, above, NMT also agrees to purchase from Lake Region
minimum unit quantities of the Product in accordance with the following schedule
for each year of the Term:

          XXXXXXXX units in first year (July 1, 1996 - June 30, 1997)
          XXXXXXXX units in second year (July 1, 1997 - June 30, 1998)
          XXXXXXXX units in third year (July 1, 1998 - June 30, 1999)
          XXXXXXXX units in fourth year (July 1, 1999 - June 30, 2000)
          XXXXXXXX units in fifth year (July 1, 2000 - June 30, 2001)

Quarters of each year end on each September 30, December 31, March 31 and June
30.

Payment by NMT to Lake Region for any shortfall of Product minimums in any year
will be handled as follows:

     (a)  If NMT has purchased 100% of its Product requirements from Lake Region
          in the shortfall year, this will cure any shortfall for that year. NMT
          will furnish to Lake Region its certification and that of C.R. Bard
          representing and warranting that NMT has purchased 100% of its Product
          that year from Lake Region and that C.R. Bard has distributed only
          Lake Region-manufactured Products that year.

     (b)  If NMT has purchased in excess of the minimum in any year, that excess
          will be applied to satisfy, in whole or in part, any shortfall for the
          year immediately following the excess year.

     (c)  If, despite (a) and (b) above, NMT must pay Lake Region for failure to
          meet its minimum in any year, NMT will pay Lake Region for the
          shortfall upon invoice from Lake Region within 30 days after the end
          of the shortfall year.

     (d)  NMT will pay Lake Region XXXXXXXX of the XXXXXXXX of the Products
          multiplied by the number of units of shortfall for failure to meet
          minimum in any year, after any application of Subsections (a) and (b),
          above.

     7.   Customer Supplied Material. It will be NMT'S obligation, at its cost,
          --------------------------                                           
to procure and provide to Lake Region, as customer-supplied material, the
Nitinol wire and rod stock specified by NMT for the Simon Nitinol Filter. It
will further be NMT's obligation to provide the customer-supplied material in
sufficient quantities, allowing for anticipated yield, and adequate lead-time so
as to support Lake Region's timely manufacture and shipment of NMT

                                     - 5 -
<PAGE>
 
product. As a minimum lead-time, Lake Region is to receive the customer-supplied
material at time of NMT's purchase order placement with Lake Region.

It will be Lake Region's obligation to provide NMT with a quarterly Inventory
Analysis of the customer-supplied material. The Inventory Analysis will include,
at a minimum, the following information:

     -    Quantity of such material available for future purchase orders

     -    Quantity of such material in Work-in-Process (WIP)

     -    Per Filter unit material requirement based on the previous Quarter's
          average loss of material throughout the manufacturing process (yield)

     8.   Other Products/Product Revisions.  Lake Region and NMT contemplate
          --------------------------------                                  
that NMT may request Lake Region to manufacture additional NMT products or
revised versions of the Product specified in Exhibit D. As agreements are made
for any such revisions which are substantial or for additional products the
parties will execute a supplement to this Agreement setting forth their mutual
agreement on price, delivery terms and other necessary and particular details
applicable to such additional products or substantial revisions. Less than
substantial revisions to the Products specified in Exhibit D do not require a
supplement to this Agreement and will be deemed to be within the definition of
the "Product" as and when such Product is manufactured by Lake Region and
delivered to NMT. ("Substantial" means: a) any re-engineering of the production
tooling or of the manufacturing process, or b) any revision to the Product which
requires FDA regulatory approval by a 510(k) or PMA submission.)

     9.   Shipping; Payment Terms. NMT acknowledges and agrees that specific
          -----------------------                                           
confirmed shipping dates may vary in duration depending upon the availability of
key materials, but Lake Region will use its reasonable best efforts to meet the
shipping schedule set forth in NMT's Purchase Orders. All NMT Purchase Orders
will bear shipping schedules for acceptance by Lake Region in writing. If Lake
Region, after such acceptance, fails to ship at least eighty (80%) percent of
the accepted Purchase Order units in any three (3) consecutive-month period for
reasons other than events specified in Section 15 or because NMT has failed to
supply in a timely manner sufficient parts which it may from time to time agree
to supply for use in manufacturing or packaging the Products, then and in such
event, NMT may, upon sixty (60) days written notice to Lake Region, manufacture
the Products directly or engage a third party to manufacture the Products;
provided that, Lake Region may cure such failure by meeting production
requirements, including make up of the three (3) consecutive-month period
shortfall, within such sixty (60) day period. Any additional costs to Lake
Region to make up any such shortfall, including overtime, extra or expedited
shipping costs and similar expenses, will be absorbed by Lake Region without any
additional cost to NMT.

     Lake Region may cure any three (3) consecutive-month period shortfall only
once during any twelve (12) consecutive-month period. In the event of any
subsequent three (3) consecutivemonth period in which Lake Region fails to ship
at least eighty (80%) percent of the accepted

                                     - 6 -
<PAGE>
 
Purchase Order units, this failure will reduce the NMT obligation set forth in
Section 4 to purchase at least seventy-five (75%) percent of its Product
requirements. Such NMT Product purchase requirements will, instead, for the
immediately following twenty-four (24) months of the Term following such
shortfall period, become the greater of:

     (a) 100% of NMT Product requirements reduced by the percentage of the Lake
Region shortfall for such three (3) consecutive-month period; * or

     (b) Fifty (50%) of NMT Product purchase requirement.

     *  Example: 1,000 units accepted with only 600 units shipped; reduces NMT's
Product purchase requirement to 60%.

     The NMT minimum purchase requirements set forth in Section 6, above, will,
for each of the two years immediately following a three (3) consecutive-month
period uncured shortfall, be reduced by the amount of such uncured shortfall.

     9.01 All sales are FOB point of shipment. Shipment will be made by the
transportation method specified by NMT where practicable. If no instructions are
provided, Lake Region will use its discretion in selecting the appropriate
transportation method. Terms of payment are Net 30 days date of invoice.

     9.02 Lake Region will send with each shipment made under this Agreement, a
certificate of conformance stating that appropriate inspection and testing has
confirmed compliance to all approved specifications for the Products in the
shipment.

     10.  Cancellation Pricing. NMT acknowledges that the Product contains
          --------------------                                            
"special materials" peculiar to the Product. NMT agrees that (a) in the event of
purchase order cancellations, NMT will purchase all Products "in process" and
all "special materials" purchased by Lake Region for use in Products specified
by such purchase orders to be shipped up to ninety (90) days subsequent to the
date Lake Region receives a written cancellation notice from NMT; and (b) when
and if, NMT directs Lake Region to switch production from Modified to Simplified
and from Simplified to SNF Filter only, NMT will purchase all obsolete parts and
components from Lake Region at Lake Region's cost.

     11.  Confidential Information.  In the performance of this Agreement,
          ------------------------                                        
proprietary information may be disclosed by one party to the other party. NMT
and Lake Region agree:

     11.01  Non-disclosure. The receiving party will not disclose to any third
            --------------                                                    
party except legal or patent counsel with whom it has an attorney-client
privilege, confidential information received from the disclosing party without
written permission from the disclosing party. Confidential information includes,
but is not limited to, engineering drawings, plans and specifications furnished
by either party to the other.

                                     - 7 -
<PAGE>
 
          Only those employees and independent contractors who need to receive
confidential information in order to carry out the purposes of this Agreement
will have access thereto, and such access will be limited only to so much of the
confidential information as is necessary for the particular employee or
independent contractor to perform his, her or its function.  Notwithstanding
anything in this Agreement to the contrary, NMT will treat all engineering
drawings, plans and specifications which relate to the Products which are
furnished to it by Lake Region as confidential information which may not be
given to any other manufacturer or intended manufacturer of the Products during
the term of this Agreement. Each party will require any other party who is given
access to any part of the confidential information to execute a reasonable and
customary form of confidentiality agreement. Any proprietary or confidential
information disclosed as a result of this Agreement will be held in confidence
for a period of three (3) years after termination of this Agreement.

     Specifically excluded from any requirements of confidentiality by NMT are:

     (a)  Any party with whom NMT contracts to manufacture or assemble non-
          filter components, whether Original, Modified or Simplified, as such
          non-filter components are identified in Exhibits A, B and C; and

     (b)  Any party with whom NMT, after expiration of this Agreement, contracts
          to manufacture the Products, with respect to such information as was
          given to NMT by Lake Region during the Term.

     11.02  Designation.  The obligations set forth in Subsection 11.01 above
            -----------                                                      
will apply only to information which is disclosed by the disclosing party in
writing and marked confidential or which is disclosed by other means, the
substance of which is promptly reduced to writing, marked confidential and the
writing transmitted to the receiving party.

     11.03  Exceptions. The obligations set forth in Subsection 11.01 above will
            ----------                                                          
have no application if the receiving party can establish by competent evidence
that:

     (a)  Such information was known to the receiving party prior to receipt
          from the disclosing party.

     (b)  Such information was available to the trade prior to its receipt from
          the disclosing party.

     (c)  Such information, through no act on the part of the receiving party,
          becomes information available to the trade or to the public.

     (d)  Such information corresponds in substance to information received in
          good faith by the receiving party from any third party which was
          lawfully in possession of and had the right to divulge such.

                                     - 8 -
<PAGE>
 
     (e)  Such information was disclosed by the disclosing party without
          restriction as to confidentiality by issuance of a patent to it, or
          otherwise.

     (f)  Such information was independently developed by an employee or agent
          of the receiving party subsequent to the receipt of such disclosure as
          can be established by reasonable proof.

     (g)  Such information was disclosed as a matter of necessity by the sale of
          the Products and any materials involved in the sale, distribution or
          use of the Products.

     12.    Duties of Lake Region. In addition to the other duties, obligations
            ---------------------                                              
and agreements of Lake Region provided for herein, Lake Region agrees that:

     12.01  Lake Region will manufacture the Products exclusively for NMT during
this Agreement and will not manufacture the Products for its own distribution or
for third parties for a period of two (2) years after the termination of this
Agreement.

     12.02  Lake Region agrees to manufacture the Products or revisions thereof
in conformity with the engineering drawings, plans and specifications drawn by
Lake Region or NMT and approved in writing by NMT as such engineering drawings,
plans and specifications may be amended from time to time. Lake Region warrants
that the Products will be free from defects in material and workmanship and that
the Products will be manufactured in accordance with current "Good Manufacturing
Practices" as required by the Food and Drug Administration ("FDA") and other
applicable rules and regulations.  Lake Region will, at its sole cost and
expense, replace any Products that are not in conformity with the plans and
specifications provided by NMT.  Lake Region makes no warranty that the Products
will be merchantable or fit for any particular purpose.  If NMT requests Lake
Region to provide engineering drawings, plans and specifications, including
amendments to such, the parties agree that such will be approved in writing by
NMT before manufacturing and that such approval by NMT will be deemed to
constitute NMT the designer, relieving Lake Region from any liability with
respect to the design of such drawings, plans, specifications and amendments,
with NMT to defend, indemnify and save harmless Lake Region for any claims,
liability or damage it may sustain due to design of the Product.

     12.03  Lake Region agrees that in the event of an FDA product recall of the
Product or a voluntary recall of the Product resulting from manufacturing/design
defects, this Agreement will then require renegotiation between them to reflect
the changed market circumstances developing from the adverse effects of such
recall.

     12.04  Lake Region agrees to maintain product liability insurance of at
least $1,000,000 bodily injury and $300,000 property damage relating to the
Products, such policy to provide for thirty (30) days prior written notice to
NMT before any material change therein or cancellation. Lake Region further
agrees to furnish NMT with a certificate of such insurance upon signing this
Agreement.

     13.    Duties of NMT. In addition to the other duties, obligations and
            -------------                                                  
agreements of NMT provided for herein:

     13.01  NMT represents and warrants that it has the unencumbered legal right
and title to the design of the Product and can validly request manufacturing of
the Product by Lake Region.

     13.02  NMT represents and warrants to Lake Region that the Products do not
infringe on patents owned or controlled by third parties and agrees to defend,
indemnify and hold Lake Region harmless against any and all claims, actions,
disputes or threatened actions thereof asserted by third parties because of the
alleged patent infringement.  NMT will defend and promptly pay Lake Region's
cost of defense, including attorneys fees and cost, in the event of such claim
or actions.  NMT may elect to control the defense of any such litigation.

     13.03  NMT agrees that, in the event that claims arise against Lake Region
for personal injuries, death, sickness, disease or property damage, and such
claims result from Products purchased by NMT and which are manufactured under
this Agreement and which conform to the Product specifications in effect at the
time of shipment of said Products by Lake Region to NMT under this Agreement,
NMT will defend, indemnify and hold Lake Region harmless from any and all

of the Inventor for the amount determined to be due pursuant to such statement
and pursuant to Section 3.1. For purposes of this Agreement, net sales shall
mean all income from items described in Section 3.4 sold and paid for, less
credits for returns, discounts, sales or similar taxes, shipping charges
separately stated on the invoice, royalties NMT is required to pay on such net
sales to a third party other than the Inventor, and similar charges that are
generally deducted in the industry to arrive at net sales.

     6.2  NMT shall keep full, true and accurate books of account of all
transactions relating to the Existing Technology and New Technology, containing
such information as may be necessary for the purpose of determining the amounts
due to the Inventor hereunder. The Inventor will receive access to the records
of NMT sufficient to enable the Inventor or a representative of the Inventor,
including the Inventor's independent certified public accountants, to verify
payments due to him. Inventor shall give notice of any objection to the royalty
statement rendered within two years from receipt thereof.

                              SECURITY AGREEMENT
                               -------------------

     7.1  NMT hereby grants to the Inventor a continuing security interest in
(a) the Existing Technology, (b) the New Technology, and (c) all collateral
covered by the Patent Mortgage (as defined below) (sometimes collectively, the
"Collateral"), which security interest is to secure the payment and performance
of all debts and obligations of NMT to the Inventor of every kind (whether or
not evidenced by a note or other instrument and whether or not for the payment
of money), liquidated or unliquidated, due or to become due, now existing or
hereafter arising, including, without limitation, all debts and obligations of
NMT (1) under a Mortgage of, Assignment of, and Grant of a Security Interest in
Patents of even date herewith from NMT to the Inventor (the "Patent Mortgage");
(2) under this Agreement; and (3) under all renewals, amendments and
substitutions of, for and to the Patent Mortgage and this Agreement
(collectively, the "Obligations"). Any sale or other disposition of the
Collateral must occur as set forth in Article XII hereof and the Inventor shall
have no right to proceeds if the Collateral is sold in accordance therewith and
subject to the

                         Technology Purchase Agreement

                                     - 6 -

security interest granted herein; provided, however, that if the Collateral is
sold or disposed of other than in accordance with Article XII hereof or other
than subject to the security interest granted herein, the Collateral shall be
deemed to include all proceeds thereof.

     7.2  NMT represents, covenants and warrants that:

          (a) NMT has not and will not subject the Collateral to any lien,
     encumbrance, security interest or financing statement whatsoever which is
     superior to that in favor of Inventor and NMT agrees, subject to the
     provisions of Article IX hereof, to defend the Collateral against any
     person claiming a superior interest therein, provided that the costs of any
     such defense shall be borne by the Inventor if the claim is determined to
     be without merit.

          (b) The place where records (except for records of any medical
     institution engaged in the clinical trials) relating to the Collateral are
     kept is situated at NMT's principal office located at 7779 Willow Glen
     Road, Los Angeles, California and the other addresses set forth on Schedule
     I, annexed hereto. NMT shall immediately notify the Inventor if such
     records are removed from the State of California and/or Boston,
     Massachusetts. Accidental or inadvertent non-notification shall not be a
     breach of this Agreement.

          (c) All information from time to time furnished to the Inventor
     concerning any of the Collateral is or will be accurate and complete in all
     material respects.

          (d) NMT will not use the Collateral in violation of law. NMT will
     immediately notify the Inventor of any loss of, and any lien or encumbrance
     on the Collateral.

          (e) At its option, the Inventor may (but shall not be obligated to)
     discharge taxes, security interests or other encumbrances at any time
     placed on the Collateral and may pay for the preservation of the
     Collateral. NMT agrees to reimburse the Inventor, on demand, for any
     payment made, or any expense incurred by the Inventor pursuant to the
     foregoing authorization with interest at the Prime Rate (as defined below)
     from time to time in effect, and such obligation, including interest, shall
     constitute Obligations hereunder. As used herein, the term "Prime Rate"
     shall mean at any time the rate per annum most recently announced by Mitsui
     Manufacturers Bank (the "Bank"), at Los Angeles, California as its prime
     rate or, if no prime rate has been announced, as its base rate or, if no
     base rate has been announced, as its minimum rate or, if the Bank has not
     announced a rate bearing any of those designations, but has announced a
     rate similar in concept to such rates, then such similar rate as announced
     by Bank. Any

                         Technology Purchase Agreement

                                     - 7 -
<PAGE>
 
     change in the interest rate hereunder shall be effective on the date on
     which a change in the Prime Rate occurs, without notice to NMT.

          (f) Until default, NMT may use the Collateral in any lawful manner not
     inconsistent with this Agreement or the Patent Mortgage, but may not sell,
     license, or otherwise dispose of any of the Collateral or any interest
     therein, except as expressly permitted in Article XII hereinbelow.

          (g) NMT will, at its cost and expense, execute and deliver all such
     additional instruments as the Inventor may require to assure to the
     Inventor his rights hereunder. Without limiting the generality of the
     foregoing, NMT will, at its cost and expense, execute and deliver any and
     all specific assignments, financing statement or other paper that may be
     necessary to the Inventor, in order to preserve and perfect any security
     interest granted to the Inventor. The right is expressly granted to the
     Inventor, at his discretion and expense (i) to file one or more financing
     statements under the Uniform Commercial Code naming NMT as debtor and the
     Inventor as secured party and identifying therein the above described
     interests in the Collateral, assignments thereof, amendments thereto and
     continuation statements therefor, without the signature of NMT wherever
     such filing is permitted by law, and (ii) to cause any and all assignments
     to NMT, pursuant to the transfer of Existing Technology set forth herein,
     of patents or patent applications filed with the United States Commissioner
     of Patents and Trademarks to reflect the Inventor's interest therein and to
     execute and deliver patent mortgages therein, concurrent with such
     assignments.

     7.3  Upon the occurrence of any one or more of the events of default set
forth in Section 8.2 hereof, all of the Obligations shall at the option of the
Inventor become immediately due and payable without notice or demand and the
Inventor may (at such time or at any time thereafter), at his option (but
subject to the provisions of Section 7.4 hereinbelow), exercise, in addition to
all other rights and remedies granted in the Technology Agreements or applicable
law, all rights and remedies of a secured party under the Uniform Commercial
Code as in effect in the Commonwealth of Massachusetts or under the applicable
law of any other applicable jurisdiction (the "UCC").

     7.4  Notwithstanding anything to the contrary set forth herein, upon the
occurrence of any event of default hereunder, and after the Inventor elects to
accelerate the Obligations pursuant to paragraph 7.3 hereof and elects to
exercise its rights and remedies as a secured party, the Inventor agrees to
exercise its remedies in the manner described in this paragraph 7.4 unless
prevented from doing so by applicable law or existing court orders (in which
case Inventor may exercise any rights or remedies available under all

                         Technology Purchase Agreement

                                     - 8 -
<PAGE>
 
applicable laws and existing court orders). Subject to said conditions, the
Inventor shall propose, before exercising his rights to sell the Collateral at a
public or private sale pursuant to the UCC, by written notification to NMT and
each other party entitled under the UCC to receive notice of such proposal, to
retain the Collateral in full and complete satisfaction of the Obligations
pursuant to Section 9-505(2) of the UCC. If prior to or during the time period
for objection provided under Section 9-505(2) of the UCC (herein called the
"Objection Period") immediately following the sending of such notification, (a)
the Inventor shall not have received any objection from any party entitled under
the UCC to object to such proposal, including, without limitation, (i) NMT or
its successors or assigns, (ii) a junior secured party, or (iii) any lienors
(including, without limitation, any governmental entity or agency claiming a tax
lien against NMT or the Collateral), (b) NMT shall not have become insolvent,
and (c) there shall not have been commenced by or against NMT a case under any
federal or state bankruptcy, insolvency or other laws relating to relief for
debtors or the readjustment, reorganization, composition or extension of debt;
then the Inventor shall retain the Collateral in satisfaction of the
Obligations. If, however, prior to or during said Objection Period, the Inventor
receives an objection to his proposal to retain the Collateral in satisfaction
of the Obligations from any party entitled under the UCC to object thereto, the
Inventor may then exercise any and all of his rights and remedies under the UCC
or other applicable law, including, without limitation, the right to sell or
dispose of the Collateral at public or private sales, in addition to his rights
and remedies provided herein. In such case, the Inventor will give NMT
reasonable notice of the time and place of any public sale of the Collateral or
of the time after which any private sale or other intended disposition thereof
is to be made. The requirement of reasonable notice shall be met if such notice
is mailed by certified mail, postage prepaid, to the address of NMT shown in
Section 13.7 of this Agreement at least twenty days before the time of the sale
or disposition. No purchaser at any sale (public or private) shall be
responsible for the application of the proceeds of sale. Before applying to the
Obligations any proceeds of the sale of Collateral, the Inventor is hereby
authorized to apply said proceeds to all costs and expenses of collecting,
holding, storing, insuring, advertising, appraising, delivering, selling, and
discharging liens or security interests on the Collateral. Expenses of retaking,
holding, selling and the like shall include reasonable attorneys' fees and
expenses. The Inventor hereby agrees that if he sells or otherwise disposes of
the Collateral by public or private sale pursuant to the (UCC, neither NMT nor
any officer or stockholder of NMT shall be liable for any deficiency resulting
from such sale; provided, however, that NMT shall be liable for such deficiency
and all of the Inventor's expenses if NMT shall have (a) committed any illegal
acts or acts in violation of this Agreement before, during or after the
Objection Period, (b) failed to assemble and provide to the

                         Technology Purchase Agreement

                                     - 9 -
<PAGE>
 
Inventor the documents relating to the Collateral, or (c) failed to comply with
any post-default obligations; and further provided that NMT's liability shall be
limited to costs or damages caused by its actions or failure to act.

     7.5  Without limiting the generality of the foregoing, the Inventor shall
have the right from time to time after the occurrence of an event of default, to
enter, during reasonable business hours, with or without legal process and
without being deemed guilty of any manner of trespass, any premises where the
Collateral (and any books, records and documents related thereto) may be found,
to take possession of the Collateral (and any books, records and documents
related thereto) and to maintain such possession where the Collateral (and any
books, records and documents related thereto) is located or to remove the
Collateral (and any books, records and documents related thereto) or any part
thereof to such other places as the Inventor may desire. NMT agrees not to
resist or interfere with any such action by the Inventor. The Inventor may
require NMT to assemble all books, records and documents related to the
Collateral and make them available to the Inventor at a place to be designated
by the Inventor.

     7.6  NMT does hereby irrevocably constitute and appoint the Inventor or any
agent designated by the Inventor, NMT's true and lawful attorney-in-fact, with
power of substitution, after the occurrence of an event of default hereunder (a)
to notify all parties having a relationship with NMT with respect to the
Collateral, including, without limitation, licensees of NMT, of the Inventor's
interest in the Collateral, and (b) to take any and all actions and execute any
and all agreements deemed necessary by the Inventor in form satisfactory to the
Inventor to effectuate the transfer of the Collateral (and all books, records
and documents related thereto) to the Inventor or to any purchaser at any public
or private sale of the Collateral pursuant to the UCC; with full authority in
the name of the Inventor or in the name of NMT to take any and all steps,
including the institution of proceedings at law or in equity that the Inventor
may think proper to effect transfer of the Collateral or to otherwise enforce or
effect the security interest granted in this Article; hereby granting unto NMT's
said attorney full power to do any and all things necessary to be done in and
about the premises as fully and effectually as NMT might or could do, and hereby
ratifying all that said attorney shall do or cause to be done by virtue hereof.
This power of attorney being coupled with an interest, shall be irrevocable
until all of the Obligations are fully paid and performed.

     7.7  NMT shall pay to the Inventor on demand any and all costs and
expenses, including but not limited to, all attorneys' fees and expenses
(whether or not any legal action or proceeding is commenced), and all other
expenses of like or unlike nature which may be expended or incurred by the
Inventor to obtain, maintain, protect, review, supervise, collect, realize or
enforce any

Obligations or any Collateral as against NMT, except if NMT shall prevail in any
such legal action or proceeding, in which case the Inventor shall pay to NMT its
costs and expenses, including attorney's fees and expenses.

     7.8  Subject to the provisions of paragraph 8.2 hereinbelow, to the full
extent permitted by law, NMT hereby waives presentment, demand, notice of
default, notice of dishonor, protest and all other forms of demand and notice
with respect to the Obligations and Collateral and all suretyship defenses.


                                  ARTICLE VIII
                               TERM; TERMINATION
                               -----------------

     8.1  This Agreement shall become valid, effective and binding on each of
the parties upon delivery of the initial payment required by Section 3.1 hereof
by NMT to the Inventor without the need for any further action on the part of
the Inventor or NMT. Unless terminated earlier by mutual consent of the parties
or pursuant to the other provisions of this Agreement, the Agreement shall
continue in full force and effect perpetually. In the event that rights to the
New or Existing Technology revert to the Inventor under this Agreement, the
provisions of Article V as they relate to NMT shall survive the termination of
this Agreement, and the provisions of Article VII shall survive.

     8.2  The events set forth below shall constitute "defaults" under this
Agreement: (i) failure of NMT to establish and implement expeditiously a
reasonable research and development program to develop and secure FDA approval
for the Filter, provided, however, that a failure to obtain FDA approval shall
not constitute a default hereunder if and so long as the Filter is being
profitably marketed outside the United States and it has been determined in good
faith by the Inventor that FDA approval cannot be secured; (ii) failure of the
research and development efforts of NMT or others working on its behalf to
produce a marketable Filter within a reasonable time, as determined by the
Inventor in good faith; (iii) failure by NMT to make any payment under the
Technology Agreements when due; (iv) failure by NMT to render any report or
statement due hereunder substantially in compliance with the terms of this
Agreement within 15 days of such date the same is due; (v) failure by NMT to use
its best efforts actively to produce, promote and market the Filter within three
months of the Approval Date; (vi) failure of NMT, beginning with the twelve (12)
month period commencing on the first anniversary of the Approval Date and
continuing for each succeeding twelve (12) month period thereafter, to make
minimum royalty payments of XXXXXXXX each such twelve (12) month period,
provided that in the event the total royalties due pursuant to Section 3.1
hereof are less than XXXXXXXX for any such twelve (12) month period, NMT shall
have the right to pay the difference in cash within seventy-five (75) days after
the end of

                         Technology Purchase Agreement

                                     - 11 -
<PAGE>
 


any such twelve (12) month period; (vii) the breach-of any representation,
warranty or covenant in this Agreement or the Patent Mortgage; (viii) the making
of any attachment on the Collateral; (ix) insolvency or termination of the
active conduct of its normal business activities of or by NMT unless the
business of NMT is continued in a successor entity; (x) the making by NMT of
any general assignment for the benefit of creditors; (xi) the commencement by or
against NMT of a case under any state or federal bankruptcy or insolvency laws;
or (xii) the entry of a decree or order against, or consent by NMT to the
appointment of a receiver, liquidator, assignee, or trustee of NMT or for any
part of the property of NMT.

     8.3  An "event of default" shall be deemed to have occurred hereunder upon
the occurrence of any default described in Section 8.2 and (except for defaults
listed in Section 8.2 (ix), (x), (xi) or (xii)) the failure by NMT to cure such
default during the 30 day period after notice thereof is given in writing by the
Inventor and received by NMT. Upon an event of default, the Inventor (i) may
exercise its rights and remedies as set forth in Article VII hereof, and (ii)
may, at his sole election, terminate this Agreement. However, if the alleged
default of NMT is other than as described in Section 8.2 (iii), (vii), (ix),
(x), (xi) or (xii) but is of such a nature that it cannot be cured within a 30
day period, then it shall be sufficient to avoid the above consequences of an
event of default that the curative process be commenced at the earliest possible
date, but in no event later than 15 days after receipt of notice, and be pursued
by NMT with due diligence in the interim.


     8.4  If this Agreement shall be terminated pursuant to Section 8.3, NMT (a)
shall return to the Inventor all tangible manifestations of the Existing
Technology and the New Technology; (b) will not make, use, sell or disclose any
of the New or Existing Technology (or any other proprietary information of the
Inventor); (c) will not make, use or sell any products derived from the New or
Existing Technology (or any other proprietary information of the Inventor); (d)
will not (except to the extent NMT independently acquires or acquired a right to
do so) assert that it has any right to prevent the Inventor or any assignee or
transferee of the Inventor from making, using, selling or disclosing or to
prevent anyone else from making, using, selling or disclosing, any of the New or
Existing Technology (or any other proprietary information of the Inventor) or
any product derived from the New or Existing Technology (or any other
proprietary information of the Inventor); and (e) will not, for a period of 5
years from and after such reversion, directly or indirectly manufacture or
market any Filter units. The Inventor shall have the right to purchase all
inventory of NMT in the event of a termination at a mutually agreeable price,

                                     - 12 -
<PAGE>
 
provided that if such a price is not agreed upon within sixty (60) days after
the date of termination, NMT shall have the right to dispose of such inventory
for a period of one hundred eighty (180) days after the conclusion of such sixty
(60) day period and such sales by NMT shall be subject to royalties under
Section 3.1.

     8.5  Payments due as of the date of termination of this Agreement shall
remain due and payable notwithstanding termination.

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

     9.1  While this Agreement is in effect, NMT shall, unless it is advised by
counsel in writing that its position is without merit, use all reasonable
measures, whether by action, suit proceeding or otherwise, to prevent the
infringement of any patent rights, or the unauthorized use or disclosure of any
of the unpatented Existing Technology, purchased under this Agreement, and for
that purpose, agrees diligently to maintain in its own name, and at its own cost
and expense, and on its own behalf, or, with the written approval of the
Inventor, at the joint expense of the Inventor and the Partnership, an.action,
suit or proceeding against any person, firm or corporation so infringing such
patent rights or improperly using or disclosing any of the unpatented Existing
Technology, necessary to prevent such infringement or unauthorized use of
disclosure and to recover damages resulting therefrom or, with the consent of
the Inventor, which consent shall not be unreasonably withheld or delayed, to
settle any claim or suit for infringement of such patent rights or for
unauthorized use or disclosure of the unpatented Existing Technology. Any
recovery of damages shall be deemed net sales for purposes of determining
royalties under Section 3.1.

     9.2  If the Inventor or NMT shall be charged with or sued for infringement
of any patent of another as a result of the use of (or licensing others to use)
any of the Existing Technology purchased under this Agreement, NMT agrees,
unless it is advised by counsel in writing that its position is without merit,
to defend at its own cost and expense or, with the approval of the Inventor, at
the joint expense of the Inventor and NMT, any such charge or suit; provided,
however, that if NMT defends such charge or suit and a final judgment is entered
against it on the infringement claim, NMT may recover one-half of its costs and
expenses of litigation and of any damages or royalties it is required to pay,
limited to the amount of the total payments to the Inventor under Section 3.1
excluding the Initial Payment. NMT shall not, in such case, be required to
undertake an appeal. NMT shall promptly notify the Inventor of any such charge
or suit; provided, however, that at the sole cost and expense of the Inventor,
NMT shall defend such litigation as the Inventor may deem necessary but with
respect to which counsel has advised NMT in writing that its position is

          compliance with Section 3.1, and LICENSEE thereafter fails to comply
          with Section 3.1 to the reasonable satisfaction of CMCC within 90

          f.   Names and addresses of all sublicensees of LICENSEE.

     5.3  With each such report submitted, LICENSEE shall pay to CMCC the
          royalties due and payable under this Agreement.  If no royalties shall
          be due, LICENSEE shall so report.

     5.4  On or before the ninetieth (90th) day following the close of
          LICENSEE's fiscal year, LICENSEE shall provide CMCC with LICENSEE's
          certified financial statements for the preceding fiscal year
          including, at a minimum, a Balance Sheet and an Operating Statement.

     5.5  The royalty payments set forth in this Agreement shall, if overdue,
          bear interest until payment at a per annum rate of XXXXXXXX the
          XXXXXXXX in effect at the XXXXXXXX on the due date.  The payment of
          such interest shall not foreclose CMCC from exercising any other
          rights it may have as a consequence of the lateness of any payment.

     6.1  CMCC shall be responsible for the preparation, filing, prosecution and
          maintenance of all patent applications and patents included in the
          Patent Rights.  LICENSEE shall reimburse CMCC for all reasonable
          attorneys' fees incurred by CMCC subsequent to the date of this
          Agreement in connection with the preparation, filing, prosecution and
          maintenance of all patent applications and patents included in the
          Patent Rights; provided that patent counsel selected by CMCC is
          reasonably acceptable to LICENSEE.  Subsequent to the date of this
          Agreement, CMCC, LICENSEE and patent counsel shall meet to develop a
          patent strategy with respect to the Patent Rights and thereafter shall
          meet on a mutually agreeable schedule to review the status thereof.
          CMCC shall furnish to LICENSEE copies of documents relevant to the
          preparation, filing, prosection or maintenance of the patent
          applications and patents included in the Patent Rights, and shall,
          upon request, provide LICENSEE copies of invoices providing detailed
          descriptions of all costs and expenses incurred by CMCC's patent
          counsel in connection therewith.

     6.2  If, at any time, CMCC shall elect not to prepare, file, prosecute or
          maintain any patent applications or patents included in the Patent
          Rights, then CMCC shall so notify LICENSEE within thirty (30) days of
          such election.  Upon receipt of such notice, LICENSEE may assume full
          responsibility, at its expense, to prepare, file, prosecute and
          maintain any such patent applications or patents.

                           ARTICLE VII--INFRINGEMENT
                           -------------------------

     7.1  Each party shall inform the other promptly in writing of any alleged
          infringement of the Patent Rights by a third party, including all
          details then available.  LICENSEE shall have the right, but shall not
          be obligated, to prosecute at its own expense any such infringements,
          and CMCC agrees that LICENSEE may join CMCC as a plaintiff at the
          expense of LICENSEE.  No settlement, consent judgment or other
          voluntary final disposition of the suit may be entered into without
          CMCC's consent, which consent shall not be unreasonably withheld,
          delayed or conditioned.

     7.2  If LICENSEE has not commenced legal action or been successful in
          obtaining cessation of the infringement within ninety (90) days of
          written notification from CMCC of such infringement, or if LICENSEE
          elects not to continue prosecuting any legal action against an
          infringer, CMCC shall have the right, but shall not be obligated, to
          prosecute at its own expense any such infringement.  CMCC may join
          LICENSEE as a plaintiff in any such infringement suit at CMCC's
          expense.  No settlement, consent judgment or other voluntary final
          disposition of the suit may be entered into without LICENSEE's
          consent, which consent shall not be unreasonably withheld, delayed or
          conditioned.

     7.3  In the event that a declaratory judgment action alleging invalidity or
          noninfringement of any of the Patent Rights shall be brought against
          LICENSEE,

                                                CONFIDENTIAL TREATMENT REQUESTED
 
          LICENSEE shall have the right, but shall not be obligated, to defend
          such action.  If LICENSEE elects not to defend such action, it shall
          notify CMCC, and CMCC, at its option, shall have the right, within
          thirty (30) days after commencement of such action, to intervene and
          take over the sole defense of the action at its own expense.

     7.4  In the event that LICENSEE shall undertake the enforcement and/or
          defense of the Patent Rights by litigation, LICENSEE may withhold up
          to XXXXXXXX of the royalties otherwise thereafter due CMCC hereunder
          and apply the same toward reimbursement of its expenses, including
          reasonable attorneys' fees, in connection therewith, but LICENSEE
          shall not withhold an amount greater than that necessary to cover the
          cost of such fees and expenses.  Any recovery of damages by LICENSEE
          for any such suit shall be applied first in satisfaction of any
          unreimbursed expenses and legal fees of LICENSEE relating to the suit,
          next toward reimbursement of CMCC for any royalties past due or
          withheld and applied pursuant to this Article VII, and to royalties
          due to CMCC for infringing sales as if sales had been made by
          LICENSEE.  The balance remaining from any such recovery shall belong
          to LICENSEE.

     7.5  In any infringement suit as either party may institute to enforce the
          Trademarks or the Patent Rights pursuant to this Agreement, the other
          party hereto shall, at the request and the 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.

     7.6  Subject to Section 2.5, LICENSEE, during the period of this Agreement,
          shall have the sole Aght in accordance with the terms and conditions
          herein to sublicense any alleged infringer for the Field of Use for
          future use of the Trademarks or the Patent Rights.

                 ARTICLE VIII -- INDEMNIFICATION AND INSURANCE
                 ---------------------------------------------

     LICENSEE covenants with CMCC as part of this Agreement that it will comply
with the indemnification and insurance terms and obligations set forth in
Sections 3.1 and 3.2 of the Bard/CMCC/Third Party Indemnification Agreement, as
well as those set forth in Sections 8, 9 and 10 of the Stock Transfer
Agreement.

                         ARTICLE IX -- EXPORT CONTROLS
                         -----------------------------

     It is understood that CMCC is subject to United States laws and regulations
controlling the export of technical data, computer software, laboratory
prototypes and other commodities (including the Arms Export Control Act, as
amended and the Export Administration Act of 1979), and that its obligations
hereunder are contingent on compliance with applicable United States export laws
and regulations.  The transfer of certain technical data and commodities may

                                      -11-
<PAGE>
 
require a license from the cognizant agency of the United States Government
and/or written assurances by LICENSEE that LICENSEE shall not export data or
commodities to certain foreign countries without prior approval of such agency.
CMCC neither represents that a license shall not be required nor that, if
required, it shall be issued.


                         ARTICLE X -- NON-USE OF NAMES
                         -----------------------------

     LICENSEE shall not use the names of CMCC nor of any of its employees, nor
any adaptation thereof, in any advertising, promotional or sales literature
without prior written consent obtained from CMCC in each case except that
LICENSEE may state that it is licensed by CMCC to the Know-How and under one or
more of the patents and/or applications comprising the Patent Rights, and
LICENSEE may comply with disclosure requirements of all applicable laws relating
to its business, including United States and state securities laws.

                             ARTICLE XI--ASSIGNMENT
                             ----------------------

     11.1 Except as otherwise provided herein, this Agreement is not assignable
          in whole or in part, and any attempt to do so shall be void.

     11.2 CMCC may assign this Agreement at any time To any corporate affiliate
          of CMCC without the prior consent of LICENSEE.

     11.3 LICENSEE may assign this agreement to another entity only with the
          prior written consent of CMCC.  CMCC agrees to consent to a proposed
          assignment after LICENSEE has demonstrated that the preconditions set
          forth in Section 14(n)(i) through (ix) of the Stock Transfer Agreement
          have been satisfied.  LICENSEE's merger with, or acquisition by,
          another entity or the sale of all or substantially all of the assets
          of LICENSEE shall be deemed an assignment for purposes of this Article
          XI.

     11.4 Any assignment in violation of this section 11 shall be null and void
          and of no force or effect.

                       ARTICLE XII -- DISPUTE RESOLUTION
                       ---------------------------------

     12.1 Either party may give the other written notice of any dispute arising
          out of or relating to the License Agreement which is not resolved in
          the ordinary course of business within a three (3) month period.
          Within fifteen (15) days of receipt of said notice, the parties shall
          meet at a mutually acceptable time and place, and thereafter as often
          as they reasonably deem necessary, to exchange relevant information
          and to attempt to settle the dispute.  If the matter has not been
          resolved within thirty (30) days of receipt of the notice provided
          above, or in the event the parties fail to meet within twenty (20)
          days of the receipt of said

                                      -12-
<PAGE>
 
          notice, either party may request in writing that the matter be
          submitted to mediation in accordance with section 12.2 below.

     12.2 Within fifteen (15) days of receipt of a request of mediation as
          described above, the parties agree to commence mediation in the City
          of Boston, Commonwealth of Massachusetts in accordance with the
          policies and procedures of Endispute, Inc. ("Endispute").  The parties
          shall select a mediator acceptable to both the CMCC and LICENSEE from
          a list provided by Endispute.  The parties agree to cooperate in good
          faith in said mediator's efforts to assist the parties to resolve the
          dispute.  Each party agrees to pay fifty percent (50%) of the costs of
          said mediation.  If the matter has not been resolved within thirty
          (30) days of the commencement of mediation, either party may request
          in writing that the matter be submitted to arbitration in accordance
          with Section 12.3 below.

     12.3 Any dispute arising under this License Agreement which is not resolved
          in accordance with either section 12.1 or 12.2 above, shall be
          determined by arbitration in the City of Boston, Commonwealth of
          Massachusetts, in accordance with the rules and regulations of the
          American Arbitration Association ("AAA").  Any such arbitration shall
          be conducted before a single arbitrator agreed upon by the parties,
          or, if the parties are unable to agree upon a mutually acceptable
          arbitrator, an arbitrator shall be chosen in accordance with AAA rules
          and regulations.  The arbitrator's determination may be filed with the
          clerk of a court of competent jurisdiction as a final adjudication of
          the matter at issue, or application may be made to such court for
          judicial acceptance of the ward and an order of enforcement, as the
          case may be.

     12.4 Nothing herein shall restrict the right of either party to institute a
          legal proceeding to enable such party to obtain provisional injunctive
          relief during the pendency of any such arbitration.

                          ARTICLE XIII -- TERMINATION
                          ---------------------------

     13.1 Except as otherwise provided herein and unless sooner terminated as
          set forth in this Article XIII, this Agreement and the licenses and
          rights granted hereunder shall remain in full force and effect until
          the expiration of the last to expire Patent Right, at which time
          LICENSEE shall have a fully paid-up, perpetual, noncancelable license.

     13.2 This Agreement shall terminate upon notice by CMCC if: (i) LICENSEE
          shall cease to carry on its business, (ii) LICENSEE shall have
          breached its obligations under the Stock Transfer Agreement or the
          Bard/CMCC/Third Party Indemnification Agreement, which breach has not
          been remedied within 15 days following written notice thereof from
          CMCC, or (iii) upon termination of the Sublicense Agreement as
          provided therein.

     13.3 Should LICENSEE fail to pay CMCC any amounts due and payable
          hereunder, CMCC shall have the right to terminate this Agreement on
          thirty (30) days' notice, unless LICENSEE shall pay CMCC within the
          thirty (30) day period, all such amounts due and payable.  Upon the
          expiration of the thirty (30) day period, if LICENSEE shall not have
          paid all such amounts due and payable, the rights, privileges and
          license granted hereunder shall terminate.

     13.4  Upon any material breach or default of this Agreement by LICENSEE,
          other than those occurrences set out in Paragraphs 13.2 and 13.3
          hereinabove and those due diligence requirements set forth in Article
          III hereto, which shall always take precedence in that order over any
          material breach or default referred to in this Paragraph 13.4, CMCC
          shall have the right to terminate this Agreement and the rights,
          privileges and license granted hereunder by one hundred twenty (120)
          days' notice to LICENSEE.  Such termination shall become effective
          unless LICENSEE shall have cured any such breach or default prior to
          the expiration of the one hundred twenty (120) day period.

     13.5 LICENSEE shall have the right to terminate this Agreement at any time
          on six (6) months' notice to CMCC, and upon payment of all amounts due
          CMCC, including all unpaid amounts of the license closing fee set
          forth in Section 4.1.a hereto, through the effective date of
          termination.

     13.6 Upon termination of this Agreement for any reason, nothing herein
          shall be construed to release either party from any obligation that
          matured prior to the effective date of such termination.  LICENSEE and
          any sublicensee thereof may, however, after the effective date of such
          termination, 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 CMCC the
          royalties thereon as required by Article IV of this Agreement and
          shall submit the reports required by Article V hereof on the sales of
          Licensed Products.

     13.7 Upon termination of this Agreement for any reason during the exclusive
          period, any sublicensee not then in default shall have the right to
          seek a license from CMCC.

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

          Pursuant to Section 10.17(b) of the Bard/CMCC Transfer Agreement, CMCC
hereby provides that LICENSEE is a third party beneficiary of the rights of CMCC
and obligations of Bard thereunder, with full rights of substitution to enforce
such rights and obligations.


                         ARTICLE XVI--CONFIDENTIAL DATA
                         ------------------------------

     16.1 Confidential Data.  As used in this Agreement the term "Confidential
          -----------------                                                   
          Data" shall mean all data or information (whether in oral, written or
          physical form) which (a) relates to the Licensed Products or either
          party and was heretofore or is hereafter furnished by one party (the
          "Disclosing Party") to the other (the "Recipient"), and (b) is
          identified by the Disclosing Party as being proprietary or
          confidential.  Confidential Data shall also include all analyses,
          compilations, studies or other documents, whether prepared by LICENSEE
          or others, which contain or reflect such information.  The term
          "Confidential Data" shall not include information which (i) was or
          becomes generally available to the public other than as a result of a
          disclosure by the Recipient or its directors, officers, employees,
          agents, or advisors, or (ii) is established by the Recipient to have
          been known to the Recipient at the time of disclosure by the
          Disclosing Party, or (iii) was or becomes available to the Recipient
          on a non-confidential basis through a source other than the Disclosing
          Party or its advisors, provided that such disclosure was not in
          violation of a confidentiality agreement of which the Recipient has or
          had knowledge.  The Sublicense Agreement shall govern the
          confidentiality obligations of the parties with respect to the Bard
          Licensed Technology.

     16.2 Non-Disclosure.  Each party agrees for a period of four years from the
          --------------                                                        
          date of this Agreement to use such reasonable efforts to prevent
          disclosure or publication of the Confidential Data of the other party
          as it uses to protect its own proprietary data of similar type or
          value.  For purposes of this Agreement, any and all data or
          information included in the Patent Rights and Know-How

                                      -15-
<PAGE>
 
          relating to the Device, and which were treated by Bard as confidential
          prior to the effective date of this Agreement, shall be treated as
          Confidential Data by LICENSEE.

     16.3 Legal Process.  In the event a Recipient is required by legal
          process to disclose any of the Confidential Data, Recipient shall
          provide the Disclosing Party with prompt notice of such requirement so
          that the Disclosing Party may seek a protective order or other
          appropriate remedy or waive compliance with the provisions of this
          Agreement relating to the protection of Confidential Data.  In the
          event that a protective order or other remedy is obtained, the
          Recipient shall use all reasonable efforts to assure that all
          Confidential Data will be covered by such order or other remedy.  If
          such protective order or other remedy is not obtained or the
          Disclosing Party waives compliance with the provisions of this
          Agreement relating to the protection of Confidential Data, the
          Recipient may disclose that portion of the Confidential Data which the
          Recipient is legally required to disclose without liability hereunder.

     17.2 CMCC and LICENSEE shall each be excused for any failure or delay in
          performing any of its respective obligations under this Agreement, if

          time as the event of Force Majeure exists.

          entire Agreement and understanding of the parties hereto as to the

          any provisions of this Agreement shall be determined to be invalid or
          unenforceable under any controlling body of law, such invalidity or

any such default in the making of such payment or in complying with such other
provisions shall continue unremedied for sixty (60) days after a written default
notice is given to NITINOL by MARKS of such default and the default is not
contested in writing by NITINOL, then MARKS, after the expiration of said sixty
(60) days and for so long as such default shall continue unremedied, may elect
at his option to terminate this Agreement by providing a written termination
notice to NITINOL.

     2.   If NITINOL, in good faith, contests any payments claimed by MARKS to
be due or other alleged defaults by NITINOL outlined in a default notice given
under Article VII, paragraph 1, NITINOL shall set forth the basis for contesting
such payments or alleged defaults in writing within sixty (60) days from the

default notice given under Article VII, paragraph 3, MARKS shall set forth the
basis for contesting such alleged defaults in writing within sixty (60) days
from the receipt of the default notice from NITINOL.  In the event this occurs,
NITINOL will not terminate this Agreement or reduce the royalty percentage and a
good faith effort will be made by both parties to settle the dispute involving
the contested defaults.  Should this effort fail, the arbitration procedure of
Article hereof will be instituted, and during such arbitration procedure,
NITINOL will escrow any royalties due hereunder pending a final decision.

     5.   If U.S. Patent No. 5,108,420 and all LICENSED PATENTS by MARKS are
declared invalid in a nonappealable judicial decision, NITINOL may terminate
this Agreement.

hereby agree to negotiate a new license for these patents at a royalty not in
excess of that set forth in Article III hereof.

                           ARTICLE XIV - ARBITRATION
                           -------------------------

                                      -9-

     1.  The parties shall arbitrate disputes in accordance with the Arbitration
Rules of the American Arbitration Association (AAA) insofar as they are not
modified by the following provisions.

     2.   Scope of Arbitration.  All controversies or claims arising out of or
relating to this agreement, or the breach thereof, shall be subject to
arbitration pursuant to this section.

     3.   Initiating Arbitration.  To initiate arbitration, the aggrieved party
shall first provide written notice to the other party specifying the issues in
dispute and its position on those issues.  Such notice must be given while the
Agreement is in effect or within three years after the termination of this
Agreement, or the aggrieved party's right to redress is entirely waived.  Within
14 days of receipt of the notice, the receiving party shall make written
response specifying its position on the issues in dispute, and the parties shall
in good faith attempt to negotiate a solution to the controversy for a further
period of 14 days after the written response.  If no written response is filed
or the dispute is not resolved during the negotiation period, the aggrieved
party shall file a demand for arbitration in writing with the other party and
with the AAA.

     4.   Effect of Arbitration.  The initiation of arbitration by written
notice as specified above shall toll any statute of limitations applicable to
the dispute.  The parties will continue to comply with all provisions and
requirements of this Agreement pending the outcome of arbitration.

     5.   Form of Arbitration.  One neutral arbitrator shall be appointed by the
AAA, and except as otherwise provided herein, all decisions and awards shall be
made by the Arbitrator.

     6.   Arbitration Management.  It shall be the Arbitrator's responsibility
to exert management initiative and control over the arbitration, including
discovery and scheduling, so that a just decision is reached as quickly as
possible and at minimum expense to the parties.  The Arbitrator will manage and
schedule proceedings, make orders and issue subpoenas for discovery, establish
protective orders to maintain confidentiality of proprietary information, decide
discovery and evidentiary disputes, and shall enforce his orders by assessing
costs and/or fines and/or directing findings on issues where appropriate.  The
decisions of the Arbitrator shall be final and binding.

     7.   Discovery.  After the arbitration notice has been filed, the parties
shall, before the hearing thereof, cooperate in discovery and mandatory
disclosure of all matters relevant to such dispute, to the extent and in the
manner provided by the Federal Rules of Civil Procedure, including making their
employees, agents, and experts available for depositions.  Discovery and
disclosure shall be completed within two months after filing of the notice of
arbitration.  The Arbitrator may extend this deadline, but only upon a showing
of exceptionally good cause, and in no event shall extensions in excess of an
additional two months be granted.

                                      -10-
<PAGE>
 
     8.   Hearings, Award, and Judgment.  All hearings shall be held at a
location designated by the Arbitrator and hearings shall be completed within two
months of the completion of discovery.  Evidence not admissible under
traditional rules of evidence may be admitted at the sole discretion of the
Arbitrator, but the weight given to evidence will be limited based on its
apparent reliability under traditional evidence law concepts.  The Arbitrator
shall render a written award within one week after the last day of hearings.
The written award shall specify the final judgment of the Arbitrator without any
reasons in support of the award.  The award shall be final and binding on the
parties as to each other, but shall have no effect as to any other party.  The
Arbitrator shall have the power to award any remedy provided under the
applicable laws.  Judgment upon the award maybe entered and enforced in any
court having jurisdiction thereof at the request of either party.  The parties
shall treat the written award as confidential and shall not reveal its specific
contents publicly or privately except to the extent required by a court order or
by securities laws.

     9.   Cost of Arbitration.  The party demanding arbitration shall pay the
arbitration management fees of the AAA.  Initially, the parties shall each pay
50% of the fees of the Arbitrator, and shall each bear their own costs of
arbitration.  However, at the time of the award, the Arbitrator shall direct the
losing party to pay the other party its reasonable legal fees and other costs of
arbitration unless the circumstances call for a different result.


                           ARTICLE XV - MISCELLANEOUS
                           --------------------------

     1.   Neither party shall be obligated to disclose any proprietary
information of a third party without the consent of such third party, nor any
information the furnishing of which would require the payment of consideration
to a third party other than an employee of the party furnishing such
information.

     2.   If any clause or part of this Agreement should be found to be invalid
for any reason, this shall not affect the effectiveness of the other clauses or
parts thereof.

     3.   Performance of the terms and conditions of this Agreement by either
party is excused whenever such performance is prevented by strike, riot, fire,
war, insurrection, the elements, acts of God or the public enemy, compliance
with any laws, regulation or other governmental order or other causes beyond the
contort of the parties.

     4.   This Agreement and all the provisions hereof shall inure to the
benefit of, and be binding upon, the heirs, distributees, successors, assigns
and legal representatives of the parties.

     5.   Each party shall notify the other party of any other patents or patent
applications of which the notifying party becomes aware, covering any adaptions
or improvements of the LICENSED PRODUCTS.

                                      -11-
<PAGE>
 
     6.   Any notice required hereunder shall be in writing and shall be deemed
to be properly given when sent registered mail.

     7.   The law of the State of New Jersey shall govern this Agreement as to
all matters, including, specifically but not exclusively, matters of
interpretation, performance and remedies, insofar as such law is existent or
applicable and can or will be applied in the jurisdiction in which either party
may seek in adjudication of any such matter.

     8.   This Agreement constitutes the entire understanding between the
parties and conclusively supersedes all prior writings and negotiations between
them.  This Agreement shall not be modified unless modification is in writing
and signed by both parties.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement.

          7.   Secrecy; Inventions.
               ------------------- 

          (a)  Harry agrees that he shall not, during or after the Employment

person, firm, corporation or other business entity, any confidential
information, including but not limited to, inventions, processes, trade secrets,

expenses in connection herewith shall be paid by NMT.


          8.   Royalty.
               ------- 

          (a)  NMT shall pay Harry a XXXXXX royalty on the Net Sales by NMT of
any product in a jurisdiction where NMT has an issued patent or pending patent
application, filed subsequent to the commencement of the Consulting Term, on an
invention of Harry. To the extent NMT does not sell products under such patent
but receives patent royalties from a third party, Harry shall receive XXXXXX of
such Patent royalties actually collected by NMT. Notwithstanding the foregoing
(a) no royalty shall be paid to Harry if his invention relates to a product
which NMT was selling as of the commencement of the Consulting Term or as to
which NMT was receiving royalty as of the commencement of the Consulting Term,
unless Harry's invention results in an increased sale price or royalty paid to
NMT, and (b) if Harry is not the sole inventor, such royalty shall be
apportioned (e.g. if there are two inventors, Harry shall receive a royalty
equal to one-half of his royalty as a sole inventor) or as unanimously directed
by the inventors. Net Sales shall be the amount actually collected by NMT and
shall not include transportation charges, freight and delivery charges, normal
trade discounts allowed to customers at the time of sale, sales, use or excise
taxes included in the gross sales price of the product, sales of samples and
occasional sales of test or experimental devices, and credits or allowances
given on account of rejection or return of products previously delivered and
paid for. Royalties shall be paid to Harry quarterly within 75 days after the
end of each calendar quarter and Harry shall have the right within one year
after receipt of a royalty statement, to have a public accountant, during normal
business hours, audit NMT's books to verify the accuracy of the royalty payments
due pursuant to this Section 8.

          (b)  Notwithstanding the foregoing, the royalty provided in paragraph
(a) above shall be reduced by XXXXXX from and after the time when Harry's
employment with NMT shall be terminated voluntarily by Harry (other than by
reason of death or disability), and shall be eliminated entirely if Harry's
employment with NMT shall be terminated voluntarily by Harry (other than by
reason of death or disability) less than three years from the commencement of
employment.


          9.   Restrictive Covenant.
               -------------------- 

          (a)  Harry agrees that during the Employment Term hereof and for a
period of 12 months next succeeding the termination of

                                      -3-
<PAGE>
 
his employment with NMT for any reason whatsoever, he will not, directly or
indirectly engage in any business activity in competition with the business then
being conducted or actively contemplated by NMT, whether for Harry's own account
or as executive, partner, officer, director, employee, consultant or  holder of
more than 5% equity interest in any other entity or person. Harry further agrees
that during said 12 month period he will not hire, offer to hire, entice away or
try to persuade any executive, employee, supplier or agent of NMT to discontinue
the relationship with NMT, or assist any member of his immediate family, any
business associate or other person, for consideration or otherwise, to do any of
the aforesaid prohibited things.

          (b)  If Harry shall breach any of this Section 9, Career Incentive
Bonus Plan benefits (or any stock option or purchase rights which may be
granted), whether vested or unvested, shall be paid or transferred to Harry
until final resolution of any claims by NMT for money damages, and NMT, in
addition to any money damages, shall be entitled to an injunction to be issued
by a court of competent jurisdiction enjoining, restraining or restricting Harry
from such breach or violation.


          10.  Relocation.  It is required that Harry be available at NMT's
               ----------                                                  
offices and therefore shall be required to relocate his residence to the
vicinity of NMT's offices. NMT shall reimburse Harry for the actual costs and
expenses of such relocation, to a maximum of $10,000.


          11.  Miscellaneous.
               ------------- 

          (a)  Neither this Agreement nor its execution and delivery has been
induced by any representation, stipulation, warranty, agreement or understanding
of any kind other than those specifically set forth herein. This Agreement
constitutes the whole agreement between the parties hereto and there are no
terms other than those contained herein. No variation hereof shall be deemed

the same time or any prior or subsequent time or of the provision or condition
itself.

the invalidity or illegality of any portion of this Agreement shall not affect
the validity or legality of the remainder hereof. If any of the provision of
this Agreement should be determined to be unenforceable by reason of being
unreasonable in duration or in area, then such provision is intended to and

                                      -4-

shall extend only for such period of time and in such area as is determined to

          9.   Restrictive Covenant.
               -------------------- 

          (a) Executive agrees that during the term hereof and for a period of
     18 months next succeeding the termination of his employment with Employer
     for any reason whatsoever, he will not directly or indirectly engage in any
     business activity in competition with the business then being conducted or
     actively contemplated by Employer, whether for Executive's own account or
     as executive, partner, officer, director, consultant or holder of more than
     5% equity interest in any other entity or person. Executive further agrees
     that during said 18 month period he will not hire, offer to hire, entice
     away or try to persuade any executive, employee, supplier or agent of
     Employer to discontinue the relationship with the Employer, or assist any
     member of his immediate family, any business associate or other person, for
     consideration or otherwise, to do any of the aforesaid prohibited things.
     During the course of said 18 month period, Executive shall advise Employer,
     in writing, if he has received and wishes to accept any offer of employment
     from such a competitor. Such writing shall be sufficiently detailed
     regarding the nature and scope of the position and compensation offered.
     The Employer shall then have thirty (30) days following the receipt of said
     written notification to advise Executive of its election:

               (i) To waive the provision of this Section 8, only in which case
          Executive shall be free to accept such employment subject to all the
          other terms and conditions set forth herein; or

               (ii) To insist upon full compliance with the provisions of this
          Paragraph 9, in which case Employer shall compensate Executive at the
          base salary rate actually offered by its competitor for the duration
          of

                                     - 3 -
<PAGE>
 
          the aforesaid 18 month period or until Executive shall be employed
          elsewhere.

          (b) If Executive shall breach any of this Section 9, all Career
     Incentive Bonus Plan benefits, whether vested or unvested, shall lapse
     until final resolution of any claims by Employer for money damages, and
     Employer, in addition to any money damages, shall be entitled to an
     injunction to be issued by a court of competent jurisdiction enjoining,
     restraining or restricting Executive from such breach or violation.

          10. Miscellaneous.
              ------------- 

          (a) Neither this Agreement nor its execution and delivery has been
     induced by any representation, stipulation, warranty, agreement or
     understanding of any kind other than those specifically set forth herein.

     condition of this Agreement shall be deemed a waiver of a breach of a
     similar or dissimilar provision or condition at the same time or any prior
     or subsequent time or of the provision or condition itself.

          (b) Each provision of this Agreement is intended to be severable and
     the invalidity or illegality of any portion of this Agreement shall not
     affect the validity or legality of the remainder hereof. If any of the
     provisions of this Agreement should be determined to be unenforceable by
     reason of being unreasonable in duration or in area, then such provision is
     intended to and shall extend only for such period of time and in such area
     as is determined to be reasonable and enforceable.

          (c) This Agreement supersedes and replaces the Agreement between the
     parties dated June 1, 1991.

                             SUPPLEMENTAL AGREEMENT

     This Supplemental Agreement by and between NITINOL MEDICAL TECHNOLOGIES,
INC., (hereinafter referred to as "EMPLOYER") and STEPHEN J. KLESHINSKI
(hereinafter referred to as "EXECUTIVE") is effective as of the First day of
June, 1994.

     WHEREAS, EMPLOYER has entered into a License Development Agreement by and
between Boston Scientific Corporation and EMPLOYER dated as of the 1st day of
November, 1994 (The "License Agreement").

     1.   EMPLOYER and EXECUTIVE are parties to a prior Agreement dated as of
the 22nd day of July, 1993 (the "Prior Agreement"), a copy of which is attached
hereto.  The purpose of this Supplemental agreement is to amend the provisions
of paragraph 8 of the Prior Agreement; but the Prior Agreement shall otherwise
remain in full force and effect.

     2.   Paragraph 8 of the Prior Agreement is hereby amended to read as
follows:

          8.  (a)    During the term of this Agreement and any renewal thereof,
     EMPLOYER shall pay EXECUTIVE a royalty with respect to any product (other
     than a product including a Stent, as that term is defined in Section 1.20
     of the License Agreement, or a Vena Cava filter product) made, used or sold
     by EMPLOYER or any licensee of EMPLOYER in any jurisdiction EMPLOYER has an
     Executive Patent (as defined below) the claims of which cover such
     manufacture, use or sale.  With respect to any such product sold by
     EMPLOYER, the royalty shall be XXXXX of EMPLOYER's Net Sales (defined
     substantially as EMPLOYER'S gross sales adjusted as provided in the
     definition of Net Sales in Section 1.14 of the License Agreement, with such
     modifications as are appropriate to the circumstances) of such products;
     with respect to any such products sold (or to be sold) by a third party
     from which EMPLOYER directly or indirectly receives any payment with
     respect to any Executive Patent, the royalty shall be XXXXX of such
     payments.  In the case of an Executive Patent in which EXECUTIVE is not the
     sole inventor, the royalty shall be apportioned (e.g., if the product is
     covered by only one Executive Patent as to which there are two inventors,
     EXECUTIVE shall receive a royalty equal to one-half the royalty which he
     would have received if he had been the sole inventor).  Notwithstanding the
     foregoing no royalty shall be paid to EXECUTIVE with respect to any such
     product if EMPLOYER establishes that no invention which is the subject of
     any Executive Patent contributed to the value of such product.

               (b) EMPLOYER shall pay EXECUTIVE an amount equal to XXXXX of all
     licensing fees actually collected by EMPLOYER in conjunction with the sale
     or licensing of Stents or Products (as such terms are defined in Section
     1.18 and 1.20 of the License Agreement).  With respect to each Stent
     Product, such amount shall be due and payable for a period of ten (10)
     years following the first commercial sale of such product in any
     jurisdiction.  In the event that EMPLOYER collects any monies from a third
     party as designated as an advance against future license fees, such monies
     shall be considered to have been collected when fully vested in EMPLOYER.

                                                CONFIDENTIAL TREATMENT REQUESTED
 
               (c) The payments to EXECUTIVE provided in subparagraphs (a) and
     (b) above shall if such be reduced by XXXXX from and after the time when
     EXECUTIVE's employment with EMPLOYER is terminated by EXECUTIVE voluntarily
     (but not by reason of death, sickness or other disability) or by EMPLOYER
     with due cause, but otherwise shall not be reduced, provided, however, that
                                                         -----------------      
     if termination under such circumstances shall occur within three years of
     the date of this Agreement said payment shall terminate.

               (d) The payments to EXECUTIVE provided in subparagraphs (a) and
     (b) above shall be made as promptly as practicable, but in any event within
     75 days at the end of each calendar quarter with respect to payments
     received by the EMPLOYER during such calendar quarter; if no payments are
     due with respect to any calendar quarter, EMPLOYER shall provide EXECUTIVE
     a statement to such effect within the 75 day period.  EMPLOYER shall keep
     complete and accurate books and records from which the amounts of such
     payments may be ascertained, and within one year after receipt of any
     payment or statement.  EXECUTIVE, or a representative of EXECUTIVE, shall
     have the right to examine such books and records during business hours once
     in each calendar year to verify the accuracy of such payment or statement.

               (e) EMPLOYER's obligations under this Paragraph 8 may be assigned
     only in connection with the sale or other transfer of all or substantially
     all of EMPLOYER's business to which the subject matter of this paragraph
     relates, and then only if the assignee agrees to be bound thereby in a
     writing delivered to EXECUTIVE in advance of such transfer.

               (f)  As used in this Paragraph 8,

               "Executive Patent" means any patent issued, and any patent
     application filed, after the effective date of the Prior Agreement in which
     EXECUTIVE is a sole or joint inventor.

               "Stent" shall have the same meaning as nitinol Stent in the
     Agreement with Boston Scientific Corporation.
