    The Notes are convertible at any time after            , 1996 and prior to
maturity, unless previously redeemed or repurchased, into shares of Common
Stock, par value $.001 per share ("Common Stock"), of Ventritex, Inc. (the
"Company") at a conversion rate of          shares per each $1,000 principal
amount of Notes (equivalent to a conversion price of approximately $         per
share), subject to adjustment in certain circumstances. On July 2, 1996, the
last reported bid price of the Common Stock, which is traded under the symbol
"VNTX" on the Nasdaq National Market, was $17 7/8 per share.
 
    Interest on the Notes is payable on          and          of each year,
commencing          , 1997. The Notes are redeemable in whole or in part at the
Company's option at any time on or after          , 1999 at the redemption
prices set forth herein, plus accrued interest to the date of redemption. See
"Description of Notes -- Optional Redemption." The Notes are not entitled to any
sinking fund. The Notes will mature on          , 2001.
 
    In the event of a Change of Control (as defined herein), each holder of
Notes may require the Company to repurchase its Notes, in whole or in part, for
cash or, at the Company's option, Common Stock (valued at 95% of the average
closing prices for the five trading days immediately preceding and including the
third trading day prior to the repurchase date) at a repurchase price of 100% of
the principal amount of Notes to be repurchased, plus accrued interest to the
repurchase date. See "Description of Notes -- Repurchase at Option of Holders
Upon a Change of Control."

of the same date, the Company's subsidiaries had no outstanding indebtedness for
money borrowed. See "Description of Notes -- Subordination."
 
    The Notes will be represented by a Global Note registered in the name of the
nominee of The Depository Trust Company ("DTC"), which will act as depositary.
Beneficial interests in the Global Note will be shown on, and transfers thereof

                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and consolidated financial statements and related notes appearing
elsewhere in this Prospectus, including information incorporated by reference
herein. Unless otherwise indicated, all information in this Prospectus assumes
that the Underwriter's over-allotment option is not exercised. As used in this
Prospectus, unless otherwise indicated, references to the "Company" and
"Ventritex" are to Ventritex, Inc. and its consolidated subsidiaries.
 
     This Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results of operations could differ
materially from those anticipated in such forward-looking statements as a result
of certain factors set forth under "Risk Factors" and elsewhere in this
Prospectus.
 
                                  THE COMPANY
 
     Ventritex, Inc. ("Ventritex" or the "Company") designs, develops,
manufactures and sells implantable defibrillators and related products for the
treatment of ventricular tachycardia and ventricular fibrillation. Ventricular
tachycardia and ventricular fibrillation are the most serious and
life-threatening forms of abnormal heart rhythms ("arrhythmias"). The Company's
principal product, the Cadet V-115 implantable defibrillator, is an electronic
device that is implanted in the patient's pectoral (chest) or abdominal region
and is connected to the patient's heart with defibrillation leads, which are
typically implanted transvenously. The Cadet V-115 is the successor to the
Company's Cadence V-100 and V-110 implantable defibrillators, which are
considerably larger than the V-115 and are implanted in the patient's abdominal
region. The Cadet has the same functional and performance characteristics as
larger Ventritex implantable defibrillators and offers features, including high
defibrillation energy output and extended electrogram ("EGM") storage, superior
to competing defibrillators that can be implanted pectorally. As of June 30,
1996, approximately 1,000 Cadet and 17,250 Cadence implants had been performed
at over 550 sites. The Company's defibrillators monitor the heartbeat and
deliver electrical pulses or shocks to the heart to terminate ventricular
tachycardia and ventricular fibrillation in patients. In ventricular
tachycardia, the heart's ventricles contract at an abnormally rapid rate and
typically deliver less blood to the body's tissues and organs. Episodes of
ventricular tachycardia occur unpredictably and can progress to ventricular
fibrillation. In ventricular fibrillation, the heart's normal electrical
impulses become disorganized and erratic and the heart ceases to pump blood. If
ventricular fibrillation is not terminated quickly, the individual will
experience a sudden cardiac death ("SCD") episode during which the individual
will become unconscious and, without prompt medical intervention, typically will
die.
 
     The Company believes that the most effective therapy for the treatment of
individuals who are at high risk of experiencing an SCD episode is generally an
implantable defibrillator. The annual mortality rate from SCD for patients
receiving an implantable defibrillator is between 1% and 3%, which is
substantially less than the annual mortality for high risk SCD patients who
receive drug therapy but do not receive an implantable defibrillator. Since the
first defibrillator implant in 1981, the Company estimates that, through 1995,
over 90,000 defibrillators had been implanted in patients in the United States,
including approximately 22,000 in 1995.
 
     The Company was incorporated in California in January 1985, and changed its
state of incorporation from California to Delaware in December 1994. The Company
maintains its principal executive offices at 701 East Evelyn Avenue, Sunnyvale,
CA 94086, and its telephone number is (408) 738-4883.
 
                              RECENT DEVELOPMENTS
 
     In May 1996, the Company received approval from the United States Food and
Drug Administration ("FDA") to expand the labeling of the Cadet V-115
defibrillator, for which the Company received FDA approval of a pre-market
approval ("PMA") supplement in December 1995, to include pectoral implantation
of the defibrillator unit. In addition, in May 1996, the Company's PMA
application for its TVL transvenous defibrillation lead system was approved by
the FDA. The combination of the Cadet V-115 defibrillator and the TVL lead
system enables the Company to offer a pectorally implantable defibrillator
 
                                        3
<PAGE>   5
 
together with a transvenous lead system, which is the preferred system
configuration for implantable defibrillators. Beginning with the quarter ended
June 30, 1995, the Company's sales and market share were adversely affected by
the introduction of pectorally implantable defibrillators by competitors, and
the Company believes that the ability to offer the Cadet for pectoral
implantation will provide the Company with an opportunity to improve its
competitive position. In addition, the Company has developed a new, smaller
implantable defibrillator, the Contour, and is developing new transvenous lead
systems. In June 1996, the Company submitted a PMA supplement for the Contour to
the FDA. To date, a limited number of Contour defibrillators have been implanted
in patients in Europe.

                                       shares per $1,000 principal amount of
                             Notes (equivalent to a conversion price of
                             approximately $          per share), subject to
                             adjustment in certain circumstances as described
                             herein. See "Description of Notes -- Conversion
                             Rights."
 
SUBORDINATION..............  The Notes are subordinated in right of payment to
                             all existing and future Senior Indebtedness (as
                             defined) of the Company. As of June 30, 1996, the
                             Company had no outstanding indebtedness that would
                             have constituted Senior Indebtedness. The Notes are
                             also effectively subordinated in right of payment
                             to all indebtedness and other liabilities of the
                             Company's subsidiaries. As of June 30, 1996, the
                             Company's subsidiaries had no outstanding
                             indebtedness for money borrowed. The Indenture will
                             not restrict the incurrence of Senior Indebtedness
                             or other indebtedness by the Company or any
                             subsidiary. See "Description of
                             Notes -- Subordination."
 
OPTIONAL REDEMPTION........  The Notes will be redeemable at the Company's
                             option, in whole or in part, at any time on or
                             after           , 1999 at the redemption prices set
                             forth herein plus accrued interest to the date of
                             redemption. See "Description of Notes -- Optional
                             Redemption."

  OF HOLDERS UPON
  A CHANGE OF CONTROL......  In the event of a Change of Control (as defined
                             herein), each holder of Notes may require the
                             Company to repurchase its Notes, in whole or in
                             part, for cash or, at the Company's option, Common
                             Stock (valued at 95% of the average closing prices
                             for the five trading days immediately preceding and
                             including the third trading day prior to the
                             repurchase date) at a repurchase price of 100% of
                             the principal amount of Notes to be repurchased,
                             plus accrued interest to the repurchase date. See
                             "Description of Notes -- Repurchase at Option of

(1) Year ended June 30, 1993 includes a charge of approximately $18.6 million
     relating to intellectual property settlements.
(2) For the purpose of calculating the ratio of earnings to fixed charges, (i)
     earnings consist of consolidated income before income taxes plus fixed
     charges and (ii) fixed charges consist of interest expense incurred,
     including capitalized leases and the portion of rental expense under leases
     deemed by the Company to be representative of the interest factor. For the
     years ended June 30, 1991, 1992 and 1993 and the nine months ended March
     31, 1996, earnings were insufficient to cover fixed charges by $6.5
     million, $7.0 million, $33.3 million and $49.2 million, respectively.

                                  RISK FACTORS
 
     In evaluating an investment in the Notes, prospective investors should
carefully consider the following risk factors in addition to the other
information appearing in this Prospectus.
 
FLUCTUATIONS IN OPERATING RESULTS; PROFITABILITY UNCERTAIN
 
     The Company incurred net losses from its inception in January 1985 through
the year ended June 30, 1993, incurred net losses from the fourth quarter of
fiscal 1995 through fiscal 1996, expects to incur a net loss for the first
quarter of fiscal 1997 and may incur a net loss for the first half of fiscal
1997. If regulatory approval to market the Contour in the United States is not
obtained by the end of the third quarter of fiscal 1997, the Company's results
of operations will be adversely affected. Results of operations have varied and
may continue to fluctuate significantly from quarter to quarter and will depend
upon numerous factors including timing of regulatory approvals, market
acceptance of the Company's products, introductions of new products with
advanced features by the Company or its competitors, technological advances in
the treatment of arrhythmias, the outcome of intellectual property litigation
and competition. Sales have fluctuated significantly in the past, especially in
fiscal 1995 and fiscal 1996, as competitors introduced products with advanced
features. In particular, the Company's net sales declined from $107.6 million in
the nine months ended March 31, 1995, to $37.7 million in the nine months ended
March 31, 1996, primarily as a result of competitors' introductions of smaller
defibrillators with advanced features. The Company's gross margins will be
dependent on production volumes, manufacturing efficiencies, royalties under
patent license agreements, warranty expense, component price fluctuations,
competitive pricing, varying product sales mix and other factors. There can be
no assurance that gross margins will improve in the future. In addition, a
significant portion of the Company's operating expenses are relatively fixed in
nature and planned expenditures are based, in part, on anticipated orders. Any
inability to adjust spending quickly enough to compensate for revenue shortfalls
may magnify the adverse impact of such revenue shortfall on the Company's
results of operations. Furthermore, there can be no assurance that the Company
will achieve profitability in the future or that profitability, if achieved,
will be sustained. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
UNCERTAINTY RELATING TO NEW PRODUCT DEVELOPMENT
 
     The Company's strategy involves the design and development of new products
for the treatment of ventricular tachycardia and ventricular fibrillation. The
product development process is time-consuming and there can be no assurance that
product development will be successfully completed, that necessary regulatory
clearances or approvals will be granted by the FDA on a timely basis, or at all,
or that the potential products will achieve market acceptance. The Company
expects defibrillators with advanced new features, such as dual chamber and
rate-responsive pacing capabilities, will be developed by its competitors.
Failure by the Company to develop, obtain necessary regulatory clearances or
approvals for, or successfully market potential new products with these and
other features could have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Products" and
"-- Research and Development."
 
SIGNIFICANT COMPETITION
 
     Competition in the market for implantable defibrillator systems is intense.
Although patients susceptible to ventricular tachycardia and ventricular
fibrillation may be treated with antiarrhythmic drugs or cardiac ablation
therapies, the Company believes that manufacturers of implantable defibrillators
are its primary competitors. The Company's principal competitors are Cardiac
Pacemakers, Inc. ("CPI"), a subsidiary of Guidant Corporation, and Medtronic,
Inc. ("Medtronic"). Both CPI and Medtronic are large, diversified cardiology and
medical device companies and each has invested substantial amounts in
implantable defibrillator research and development. Other competitors in the
implantable defibrillator market include Telectronics Pacing Systems, Inc., a
subsidiary of Pacific Dunlop Limited ("Telectronics"), Intermedics, Inc., a
subsidiary of Sulzer Brothers Ltd. ("Intermedics") and Angeion Corporation.
 
                                        6
<PAGE>   8
 
     In March 1995, the FDA approved the commercial release of new
defibrillators manufactured by CPI and Medtronic which are small enough to allow
pectoral implantation, rather than abdominal implantation, in suitable patients.
Until receipt of regulatory approval relating to the Cadet in May 1996, the
Company could not offer an implantable defibrillator labeled for pectoral
implantation in patients in the United States. Commercial release of pectorally
implantable defibrillators significantly increased competition in the
implantable defibrillator market and resulted in a significant decline in the
Company's market share and sales of the Company's products. The Company now has
products which it believes are competitive; however, there can be no assurance
that the Company's products will compete successfully with products currently
manufactured by others or future products under development by competitors which
have new features, such as dual chamber and rate-responsive pacing capabilities.
 
     Medtronic and CPI have regulatory approval of and are commercially
marketing single lead transvenous lead systems. The Company currently is
marketing the TVL transvenous lead system, a dual lead system. Some physicians
prefer a single lead system due to the perceived ease of implanting such a
system as compared to a dual lead system. The Company is engaged in clinical
trials of single lead transvenous defibrillation lead systems and must receive
regulatory approval prior to commercialization. There can be no assurance as to
when or whether the Company will receive regulatory approval for these systems.
To date, a large percentage of the Company's sales of defibrillators have been
at the direction of physicians who used the Company's defibrillators in
combination with commercially available transvenous lead systems supplied by the
Company's competitors. Therefore, there can be no assurance that physicians will
purchase transvenous lead systems for which the Company obtains regulatory
approval. In particular, physicians preferring single lead systems may choose to
continue to combine competitors' transvenous leads with the Company's
defibrillators, at least until such time as the Company obtains PMA approval for
its single lead systems. Furthermore, there can be no assurance that
manufacturers of competing transvenous lead systems will not attempt to
discourage or prevent use of their leads with the Company's defibrillators
through product labeling, availability, pricing or other means. In general,
unless the FDA-approved labeling includes use with any transvenous lead system
sold by its competitors, the FDA or other government agencies may take further
actions, including restrictions on reimbursement, to restrict the combination of
the Company's defibrillators with such transvenous lead systems. Such actions
could make the Company's defibrillators, including both the Cadet and the
Contour, less attractive to physicians and could therefore have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business -- Transvenous Lead Systems."
 
     Many of the Company's competitors, including both CPI and Medtronic, have
substantially greater financial, manufacturing, marketing and technical
resources than those of the Company. The financial resources of certain of the
Company's competitors may enable them to use pricing pressures as a means of
competition. In addition, competitors have in the past and may in the future
employ litigation to gain a competitive advantage. There can be no assurance
that the Company's competitors will not develop or obtain regulatory approval
for implantable defibrillation systems, or for pharmaceuticals or surgical
alternatives, that may be more effective in treating ventricular tachycardia and
ventricular fibrillation than the Company's current or future products, or that
the Company's technologies and products would not be rendered less competitive
or obsolete by such developments. See "Business -- Competition."
 
TECHNOLOGICAL CHANGE RESULTING IN PRODUCT OBSOLESCENCE
 
     Market acceptance and sales of the Company's products have historically
been and could in the future be adversely affected by technological changes.
Many companies with substantially greater resources than the Company are engaged
in the development of products and approaches for the treatment of ventricular
tachycardia and ventricular fibrillation. These include implantable devices as
well as pharmaceuticals and cardiac ablation therapies. Future innovations in
the treatment of ventricular tachycardia and ventricular fibrillation could
render existing technologies, and the Company's products, less competitive or
obsolete. See "Business -- Competition."
 
                                        7
<PAGE>   9
 
UNCERTAINTY OF MARKET ACCEPTANCE
 
     Market acceptance of the Company's implantable defibrillator systems will
depend in part on the therapeutic capabilities and operating features of such
systems as compared to other implantable defibrillators, physicians' willingness
to use the Company's defibrillators with competitors' transvenous defibrillation
leads, and the Company's ability to convince the medical community of the
clinical efficacy of its systems. If regulatory approval to market the Contour
in the United States is not obtained by the end of the third quarter of fiscal
1997, the Company's results of operations will be adversely affected. Failure of
the Company's products, including the Contour, to gain market acceptance or
limited growth in the market for implantable defibrillators would have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
PATENTS, PROPRIETARY RIGHTS AND RELATED LITIGATION
 
     The segment of the medical device market that includes implantable
defibrillators has been characterized by extensive litigation regarding patents
and other intellectual property rights. In 1990, two of the Company's
competitors, Telectronics and Intermedics, instituted patent infringement
litigation against the Company. Medtronic and CPI also notified the Company that
they believed the Company infringed patents held by them. The Telectronics suit
and the claims of Medtronic and CPI have been resolved through cross-license
arrangements. See "Business -- Patents and Proprietary Rights."
 
     The pending litigation with Intermedics has resulted and will continue to
result in substantial expense to the Company and significant diversion of effort
by the Company's technical and management personnel. An adverse determination in
the pending proceeding could subject the Company to significant liabilities and
could prevent the Company from manufacturing or selling its products, which
would have a material adverse effect upon the Company's business, financial
condition and results of operations and could adversely affect the Company's
ability to continue as a viable entity. Previous litigation against the Company
involving allegations of trade secret misappropriation was resolved in the
Company's favor. See "Business -- Legal Proceedings."
 
     Although the Company believes that it has entered into license agreements
with all of the major participants in the implantable defibrillator market other
than Intermedics, there can be no assurance that other parties will not
institute litigation against the Company. In addition, the license agreements
with Medtronic, Telectronics and CPI do not include patents issued under
applications filed after certain specified dates and thus future patent disputes
with Medtronic, Telectronics and CPI are possible. Any future litigation, as
well as any future interference proceedings that may be declared by the United
States Patent and Trademark Office to determine the priority of inventions,
could result in substantial expense to the Company and significant diversion of
effort by the Company's technical and management personnel. Additional
litigation may be necessary to enforce patents issued to or held by the Company,
to protect trade secrets or know-how owned by the Company or to determine the
enforceability, scope and validity of the proprietary rights of others. An
adverse determination in litigation or interference proceedings to which the
Company is or may become a party could subject the Company to significant
liabilities to third parties or require the Company to seek licenses from third
parties. There can, however, be no assurance that necessary licenses would be
available to the Company on satisfactory terms or at all. Accordingly, an
adverse determination in a judicial or administrative proceeding or failure to
obtain necessary licenses could prevent the Company from manufacturing and
selling its products, which would have a material adverse effect on the
Company's business, financial condition and results of operations and could
adversely affect the Company's ability to continue as a viable entity. See
"Business -- Patents and Proprietary Rights."
 
     The Company files patent applications to protect technology and inventions
that are significant to the development of its business. There can be no
assurance that any of the claims in the Company's pending patent applications
will be allowed, or that any issued patents will be upheld, or not circumvented
by competitors, or that any patents or licenses will provide competitive
advantages for the Company's products. The Company also relies on trade secrets
and proprietary know-how which it seeks
 
                                        8
<PAGE>   10
 
to protect, in part, through confidentiality agreements with employees,
consultants and other parties. There can be no assurance that these agreements
will not be breached, that the Company would have adequate remedies for any
breach, or that the Company's trade secrets will not otherwise become known to
or independently developed by competitors.
 
DEPENDENCE ON SOLE SOURCES OF SUPPLY
 
     The Company relies on outside suppliers to manufacture certain major
components of its defibrillator systems. The Company currently has sole source
supply arrangements with its suppliers of hybrid circuits, high voltage
capacitors, integrated circuits, defibrillation lead components, batteries and
certain other components used in its products. For certain components, there are
relatively few potential sources of supply and establishment of additional or
replacement suppliers for these components cannot be accomplished quickly. The
Company has experienced shortages of certain critical components due to
manufacturing yield problems at its suppliers. The Company believes that
alternative sources of supply are available for most components and
subcontracted manufacturing services, and plans to qualify additional suppliers
as production volumes increase. However, there can be no assurance that future
production problems will not be encountered in producing the Cadet, expanding
production of the Contour and the TVL or establishing production of other new
products. In addition, because of the long lead times for some components that
are currently available from only a single source, a vendor's inability to
supply acceptable components in the quantity required could impair the Company's
ability to manufacture new or existing products on a timely and cost effective
basis, could result in substantial unanticipated expenses and delays in the
commercial availability of such products and could have a material adverse
effect on the Company's business, financial condition, and results of
operations. See "Business -- Manufacturing."
 
RISK OF PRODUCT RECALL
 
     The Company's implantable defibrillator systems include a complex
electronic device and leads designed to be implanted in the human body for long
periods of time. Component failures, manufacturing errors or design defects
could result in an unsafe condition, injury or death to the patient. The
occurrence of such a problem could result in a recall of the Company's products,
explanting implanted defibrillators or leads and the implanting of new
defibrillators or leads.
 
     Previously, the Company experienced certain component failures with the
Cadence defibrillators and with lead systems. For example, during clinical
trials, a small number of Cadence V-100 defibrillators experienced premature
battery depletion due to defective capacitors supplied by an outside vendor. In
all these instances, the devices were explanted and replaced with new
defibrillators. The Company has experienced what it believes, in light of
industry experience, to be a typical level of returns of defibrillator units
from the field for various reasons, none of which the Company believes are
systemic or would otherwise give rise to a product recall. There can, however,
be no assurance that the Company's products will not experience additional
performance difficulties. Future product problems resulting in a recall could
have a material adverse effect on the Company's business, financial condition,
and results of operations. See "Business -- Manufacturing" and "-- Product
Warranty."
 
PRODUCT LIABILITY AND AVAILABILITY OF INSURANCE
 
     The manufacture and sale of the Company's products entail the risk of
product liability claims. Although the Company maintains product liability
insurance with coverage limits of $25.0 million per occurrence and $25.0 million
in the aggregate per year, there can be no assurance that the coverage limits of
the Company's insurance policies will be adequate. Product liability insurance
is expensive and may not be available in the future on acceptable terms or at
all. In addition, the Company has indemnified certain of its component suppliers
for certain potential product liability. To date, the Company has not
experienced any material product liability claims. A successful claim brought
against the Company in excess of its insurance coverage could have a material
adverse effect on the Company's business, financial condition and results of
operations and could adversely affect the Company's ability to continue as a
viable entity. Also, as a result of the June 1996 United States Supreme Court
decision in Medtronic,
 
                                        9
<PAGE>   11
 
Inc. v. Lohr, which rejected federal pre-emption of certain state law causes of
action in relation to medical devices, the Company expects that product
liability claims relating to medical devices may be pursued more aggressively in
the future. See "Business -- Product Warranty."
 
GOVERNMENT REGULATION
 
     The Company's products and manufacturing activities are subject to
extensive and rigorous government regulation. In the United States, all
Ventritex products are classified as class III devices, which are subject to the
most stringent FDA review. These devices require submission and approval of a
PMA application or PMA supplement from the FDA before commencement of commercial
marketing, sales and distribution in the United States. If a PMA is granted,
significant modifications to the device, manufacturing process or labeling will
require a supplemental PMA or require the submission of a new PMA application,
which could require substantial additional efficacy and safety data and FDA
review. The Company is pursuing approval of PMA supplements, including a
supplement relating to the Contour. These supplements may not be accepted by the
FDA. The FDA may require clinical data in order to approve these supplements.
The Company would then be required to conduct an additional clinical trial under
an investigational device exemption ("IDE") and submit data for such trial in
order to commercialize the product. This could result in significant delays in
approval for such products, which delays could have a material adverse effect on
the Company's business, financial condition and results of operations.
Commercial distribution in certain foreign countries is also subject to
extensive government regulation.
 
     The process of obtaining FDA and other required regulatory approvals is
lengthy, expensive and uncertain. Moreover, regulatory approvals, if granted,
may include significant limitations on the indicated uses for which a product
may be marketed. In addition, the FDA may require testing and surveillance
programs to monitor the effect of approved products which have been
commercialized and it has the power to prevent or limit further marketing of a
product based on the results of these post-marketing programs. The FDA actively
enforces regulations prohibiting marketing of products for non-indicated uses.
In addition to FDA inspections conducted prior to the approval of a PMA
application, the FDA also conducts periodic inspections to determine compliance
with current Good Manufacturing Practice ("GMP") and Medical Device Reporting
("MDR") regulations. Failure to comply with applicable regulatory requirements
can result in, among other things, fines, suspensions or delays of approvals,
seizures or recalls of products, operating restrictions and criminal
prosecutions. Furthermore, changes in existing regulations or adoption of new
regulations could prevent the Company from obtaining, or affect the timing of,
future regulatory approvals. There can be no assurance that the Company will be
able to obtain necessary regulatory approvals on a timely basis or at all.
Delays in receipt of or failure to receive such approvals or loss of previously
received approvals could have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business -- Government Regulation."
 
LIMITATIONS ON THIRD PARTY REIMBURSEMENT
 
     Implantable defibrillators are generally purchased by hospitals upon
recommendations of electrophysiologists. Typically, these hospitals then bill
various third party payors for the health care services provided to their
patients. These payors include Medicare, Medicaid and private insurers.
Government agencies reimburse hospitals for medical procedures at rates based
upon Diagnostic-Related Groups ("DRGs").
 
     Third party payors are increasingly challenging the prices charged for
medical products and services, and current levels of reimbursement may be a
disincentive to some hospitals to perform defibrillator implants. Currently, the
sales prices of implantable defibrillators range from approximately $12,000 to
$20,000, excluding leads. According to an industry study published in January
1995, a defibrillator implant procedure, excluding electrophysiology testing,
typically costs between $30,000 and $60,000, depending on the length of hospital
stay and other variables. The same source indicated that the average Medicare
reimbursement for an initial defibrillator implant procedure is approximately
$35,000 to $40,000 and that the average Medicare reimbursement for defibrillator
replacement proce-
 
                                       10
<PAGE>   12
 
dures is approximately $20,000. Consequently, despite the Company's receipt of
regulatory approvals for its systems, third party payors may deny full
reimbursement. There can be no assurance that the Company's implantable
defibrillator systems will be considered cost effective by third party payors,
that reimbursement will be available, or if reimbursement is available, that
third party payors' reimbursement policies will not adversely affect the
Company's ability to sell its products on a profitable basis. The failure by
hospitals and other users of the Company's products to obtain reimbursement from
third party payors could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     In addition, legislative initiatives relating to health care reform have
been introduced in Congress and certain state legislatures. These initiatives
have been focused, in large part, on health care cost containment. Such
initiatives, if enacted, could adversely affect the availability of third party
reimbursement for the Company's products and the price levels at which the
Company is able to sell its products. The Company's business, financial
condition and results of operations could be adversely affected by changes in
government and private payors' reimbursement policies relating to procedures
using the Company's products.
 
     Medicare and Medicaid policies currently permit reimbursement for
investigational medical devices if such devices represent evolutionary
modifications to commercially available products. Under this policy, for
example, next generation implantable defibrillators in clinical trials would be
eligible for reimbursement because these devices are derived from an existing,
approved class of products. Because the Company anticipates that it will be
required to conduct clinical trials in connection with future products, changes
in this reimbursement policy could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Third Party Reimbursement."
 
SIGNIFICANT RESTRICTIONS ON CHANGE OF CONTROL AND CERTAIN MINORITY INVESTMENTS
 
     The Company has adopted a number of anti-takeover measures. The Company has
adopted a Preferred Shares Rights Agreement, sometimes referred to as a poison
pill, designed to prevent hostile takeovers not approved by the Board of
Directors. In addition, the Company is authorized to issue 5,000,000 shares of
undesignated Preferred Stock. Such shares of Preferred Stock may be issued by
the Company without stockholder approval upon such terms as the Company's board
of directors may determine. The issuance of Preferred Stock may have the effect
of delaying, deferring or preventing a change in control of the Company, may
discourage bids for the Company's Common Stock at a premium over the market
price of the Common Stock and may adversely affect the market price of and the
voting and other rights of, the holders of Common Stock. At present, the Company
has no plans to issue any of the Preferred Stock.
 
     In addition, the Company's cross-licenses with Medtronic, Telectronics and
CPI, entered into in connection with the settlement of several intellectual
property litigation matters and disputes, contain significant restrictions that
may have the effect of preventing or substantially impeding an acquisition of,
change in control of, or certain minority investments in, the Company. Such
restrictions include the termination of various licenses and the requirement
that the Company make a substantial payment to one of the licensors upon such
event. See "Risk Factors -- Limitations on Repurchase of Notes" and "Description
of Capital Stock -- Preferred Shares Rights Agreement."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company is dependent upon a limited number of key management and
technical personnel. In addition, the Company's future success will depend in
part upon its ability to attract and retain highly qualified personnel. The
Company competes for such personnel with other companies, academic institutions,
government entities and other organizations. There can be no assurance that the
Company will be successful in hiring or retaining qualified personnel. Loss of
key personnel or the inability to hire or retain qualified personnel could have
a material adverse effect on the Company's business, financial condition and
results of operations.

FUTURE CAPITAL REQUIREMENTS
 
     Although the Company anticipates that the net proceeds of this offering
will be sufficient to meet the Company's foreseeable capital requirements, there
can be no assurance that the Company will not require additional financing. The
Company's liquidity and capital requirements will depend upon numerous factors,
including timing of regulatory approvals, market acceptance of the Company's
products, introductions of new products with advanced features by the Company or
its competitors, technological advances in the treatment of arrhythmias, outcome
of intellectual property litigation and competition. Future financings may
result in the issuance of senior securities or in dilution to holders of the
Company's Common Stock. Any such financing, if required, may not be available on
satisfactory terms or at all. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
VOLATILITY OF STOCK PRICE
 
     The market price of the Company's Common Stock has been and is likely to
continue to be highly volatile. In addition, the stock market and the medical
technology sector in particular have from time to time experienced significant
price and volume fluctuations that are unrelated to the operating performance of
particular companies. Factors such as fluctuations in the Company's operating
results, shortfalls in revenue or earnings from levels expected by securities
analysts, new product introductions by the Company or its competitors,
announcements of technological innovations or new products by the Company or its
competitors, governmental regulation, developments with respect to patents or
proprietary rights and litigation relating thereto, public concern as to the
safety of products developed by the Company or others and general market
conditions may have a significant adverse effect on the market price of the
Common Stock.
 
     Substantially all of the shares of Common Stock held by current
stockholders of the Company are eligible for immediate sale in the public
market, subject in some cases to the public information, manner of sale, volume
limitation and notice of sale provisions of federal securities laws. Future
sales of such shares could lead to a decline in the market price of the Common
Stock. See "Price Range of Common Stock."
 
SUBORDINATION
 
     The Notes will be unsecured and subordinated in right of payment in full to
all existing and future Senior Indebtedness of the Company. As a result of such
subordination, in the event of the Company's liquidation or insolvency, payment
default with respect to Senior Indebtedness, a covenant default with respect to
Senior Indebtedness, or upon acceleration of the Notes due to an event of
default, the assets of the Company will be available to pay obligations on the
Notes only after all Senior Indebtedness has been paid in full, and there may
not be sufficient assets remaining to pay amounts due on any or all of the Notes
then outstanding. The Company may from time to time incur indebtedness
constituting Senior Indebtedness. The Notes are structurally subordinated to the
liabilities, including trade payables, of the Company's subsidiaries. The
Indenture does not prohibit or limit the incurrence of Senior Indebtedness or
the incurrence of other indebtedness and other liabilities by the Company or its
subsidiaries. The incurrence of additional indebtedness and other liabilities by
the Company or its subsidiaries could adversely affect the Company's ability to
pay its obligations on the Notes. In addition, the cash flow and ability of the
Company to service debt, including the Notes, may in the future become dependent
in part upon the earnings from the business conducted by the Company through
subsidiaries and distribution of those earnings, or upon loans or other payments
of funds by those subsidiaries to the Company. As of June 30, 1996, the Company
had no outstanding indebtedness that would have constituted Senior Indebtedness.
As of the same date, the Company's subsidiaries had no outstanding indebtedness
for money borrowed. See "Description of Notes -- Subordination."
 
                                       12
<PAGE>   14
 
LIMITATIONS ON REPURCHASE OF NOTES
 
     Upon a Change of Control, each holder of Notes will have the right, at the
holder's option, to require the Company to repurchase all or a portion of such
holder's Notes. If a Change of Control were to occur, there can be no assurance
that the Company would have sufficient funds to pay the repurchase price for all
Notes tendered by the holders thereof. (The Company may also elect to make such
payment using shares of Common Stock.) In addition, the Company's repurchase of
Notes as a result of the occurrence of a Change of Control may be prohibited or
limited by, or create an event of default under, the terms of agreements related
to borrowings which the Company may enter into from time to time, including
agreements relating to Senior Indebtedness. See "Risk Factors -- Significant
Restrictions on Change of Control and Certain Minority Investments" and
"Description of Notes -- Repurchase at Option of Holders Upon a Change of
Control."
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
     The Notes will be a new issue of securities with no established trading
market. The Underwriter has advised the Company that it intends to make a market
in the Notes. The Underwriter is not obligated, however, to make a market in the
Notes, and any such market making may be discontinued at any time at the sole
discretion of the Underwriter without notice. There can be no assurance that an
active market for the Notes will develop and continue upon completion of the
offering or that the market price of the Notes will not decline. Various factors
such as changes in prevailing interest rates or changes in perceptions of the
Company's creditworthiness could cause the market price of the Notes to
fluctuate significantly. The trading price of the Notes could also be
significantly affected by the market price of the Common Stock, which could be
subject to wide fluctuations in response to a variety of factors, including
quarterly variations in operating results, announcements of technological
innovations or new products by the Company or its competitors, developments in
patents or other intellectual property rights, general conditions in the
industry and general economic and market conditions. The Notes will not be
listed on any securities exchange or quoted on the Nasdaq Stock Market and will
only be traded on the over-the-counter market.
 
                                USE OF PROCEEDS
 
     The net proceeds to be received by the Company from the sale of the Notes
offered hereby, after deducting underwriting discount and other expenses of the
offering, are estimated to be $86.8 million ($96.5 million if the Underwriter's
over-allotment option is exercised in full).
 
     The Company plans to use the proceeds from the sale of the Notes for
general corporate purposes, including research and development and any potential
acquisitions. Pending such uses, the Company intends to invest such proceeds in
short-term investment grade, interest-bearing instruments. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources."

(1) For the purpose of calculating the ratio of earnings to fixed charges, (i)
    earnings consist of consolidated income before income taxes plus fixed
    charges and (ii) fixed charges consist of interest expense incurred,
    including capitalized leases, and the portion of rental expense under leases
    deemed by the Company to be representative of the interest factor. For the
    years ended June 30, 1991, 1992 and 1993 and the nine months ended March 31,
    1996, earnings were insufficient to cover fixed charges by $6.5 million,
    $7.0 million, $33.3 million and $49.2 million, respectively.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following Management's Discussion and Analysis of Financial Condition
and Results of Operations should be read in conjunction with the Consolidated
Financial Statements and the related notes thereto included elsewhere in this
Prospectus and contains forward-looking statements that involve risks and
uncertainties. The Company's actual results of operations could differ
materially from those anticipated in such forward-looking statements as a result
of certain factors set forth under "Risk Factors" and elsewhere in this
Prospectus.
 
OVERVIEW
 
     Since its inception, the Company and its subsidiaries have engaged in the
design, development, manufacture and sale of implantable defibrillators and
related products. In April 1993, the FDA approved the Company's PMA for
commercial release of the Cadence V-100 system. In July 1994, the FDA approved
the Company's PMA supplement for the Cadence V-110 system, a smaller, lighter
version of the Cadence V-100. In December 1995, the FDA approved the PMA
supplement for the Cadet V-115 defibrillator system for abdominal implantation
only. In May 1996, the FDA approved the PMA supplement to label the Cadet V-115
for pectoral implantation. Also in May 1996, the FDA approved the PMA for the
TVL transvenous lead system. The Cadet V-115 is smaller and lighter than the
Cadence V-100 and V-110 implantable defibrillators but has the same or improved
functional and performance characteristics.
 
     In March 1995, the FDA approved the commercial release of new
defibrillators manufactured by CPI and Medtronic which are small enough to allow
pectoral implantation, rather than abdominal implantation,
 
                                       17
<PAGE>   19
 
in suitable patients. Until receipt of regulatory approval relating to the Cadet
in May 1996, the Company could not offer an implantable defibrillator labeled
for pectoral implantation in patients in the United States. Commercial release
of pectorally implantable defibrillators significantly increased competition in
the implantable defibrillator market and resulted in a significant decline in
the Company's market share and sales of the Company's products. The Company now
has products which it believes are competitive; however, there can be no
assurance that the Company's products will compete successfully with products
currently manufactured by others or future products under development by
competitors which have new features, such as dual chamber and rate-responsive
pacing capabilities.
 
     The Company incurred net losses from its inception in January 1985 through
the year ended June 30, 1993, incurred net losses from the fourth quarter of
fiscal 1995 through fiscal 1996, expects to incur a net loss for the first
quarter of fiscal 1997 and may incur a net loss for the first half of fiscal
1997. If regulatory approval to market the Contour in the United States is not
obtained by the end of the third quarter of fiscal 1997, the Company's results
of operations will be adversely affected. Results of operations have varied and
may continue to fluctuate significantly from quarter to quarter and will depend
upon numerous factors including timing of regulatory approvals, market
acceptance of the Company's products, introductions of new products with
advanced features by the Company or its competitors, technological advances in
the treatment of arrhythmias, the outcome of intellectual property litigation
and competition. Sales have fluctuated significantly in the past, especially in
fiscal 1995 and fiscal 1996, as competitors introduced products with advanced
features. In particular, the Company's net sales declined from $107.6 million in
the nine months ended March 31, 1995, to $37.7 million in the nine months ended
March 31, 1996, primarily as a result of competitors' introductions of smaller
defibrillators with advanced features.
 
RESULTS OF OPERATIONS
 
  NINE MONTHS ENDED MARCH 31, 1996 AND 1995
 
  Net Sales
 
     For the first nine months of fiscal 1996, net sales were $37.7 million, a
decrease of $69.9 million, or 65%, compared to $107.6 million during the first
nine months of the prior fiscal year. The decrease reflects lower unit shipments
and average unit pricing as compared to the first nine months of fiscal 1995 due
to the competitive environment. For the first nine months of fiscal 1996, unit
shipments decreased approximately 62% from fiscal 1995 levels and average unit
prices decreased approximately 8%. Sales of defibrillators provided
substantially all of the Company's revenues in both periods.
 
  Gross Profit
 
     Gross profit for the first nine months of fiscal 1996 was a loss of $0.9
million compared to a profit of $61.3 million in the corresponding period of
fiscal 1995. The decreased gross profit reflects substantial reductions in unit
shipments, increased provisions for excess and obsolete inventory, decreased
production levels and lower average unit prices in the current fiscal year.
Production levels in the first nine months of the current fiscal year were
approximately 59% lower than those in the corresponding period of the prior
fiscal year, reflecting the decrease in unit shipments. The first nine months of
fiscal 1996 includes a provision of $14.6 million for potentially excess
inventory and cancellation of purchase commitments for components utilized in
currently released products. These provisions resulted from the rapid adoption
of competitors' defibrillators that allow pectoral, rather than abdominal,
implantation in suitable patients and the approval of additional competitive
defibrillator systems labeled for pectoral implantation.
 
     During the first half of fiscal 1996, in anticipation of regulatory
approval, the Company began production of its Cadet V-115 defibrillator system
and TVL transvenous lead system, and initially experienced shortages of certain
critical components due to manufacturing yield problems at its suppliers. As a
result, supplies of the Cadet V-115 defibrillator system have been limited.
There can be no assurance that future production problems will not be
encountered in producing the Cadet, expanding
 
                                       18
<PAGE>   20
 
production of the Contour and the TVL or establishing production of other new
products. Failure to manufacture new or existing products on a timely and cost
effective basis, could result in substantial unanticipated expenses, delays in
the commercial availability of such products, and could have a material adverse
effect on the Company's business, financial condition and results of operations.
 
  Operating Expenses
 
     For the first nine months of fiscal 1996, operating expenses were $50.6
million, a 6% increase over the $47.6 million of such expenditures in the
corresponding period of the prior fiscal year.
 
     Research and development expenditures were $22.5 million in the first nine
months of fiscal 1996 compared to $20.6 million during the corresponding period
of fiscal 1995. The increase in spending was primarily due to costs incurred
associated with early production stages of the Cadet defibrillator system in
addition to design costs for future products. The Company's research and
development expenses relate to various research, product and process
development, clinical trial and quality assurance activities. Ventritex plans to
continue to invest in research and development and expects such expenses to
continue to increase in dollar amount in the future.
 
     Selling, general and administrative expenses totaled $28.1 million in the
first nine months of fiscal 1996 compared to $27.0 million during the first nine
months of fiscal 1995. The increase in spending for the first nine months of
fiscal 1996 is due to increased expenses for the newly-formed German subsidiary
and amortization costs of external equipment, partially offset by decreases in
commission expenses as a result of decreased revenues as discussed above and the
impact of provisions for potential doubtful accounts receivable which were
booked in fiscal 1995, while no such provisions were booked in the current
fiscal year. Legal expenses decreased approximately $0.3 million in the first
nine months of fiscal 1996 from fiscal 1995 levels, but are expected to increase
significantly in future periods as the Intermedics litigation moves beyond
jurisdictional matters. See "Business -- Legal Proceedings."
 
  Other Income
 
     Other income, consisting primarily of interest income, was $2.4 million in
the first nine months of fiscal 1996, compared to $2.2 million in the first nine
months of fiscal 1995. Fluctuations in interest income reflect changes in
invested cash balances and interest rates.
 
  Income Taxes
 
     The Company has established a valuation allowance for deferred tax assets
resulting from operating losses incurred in fiscal 1996; accordingly, no tax
benefit has been recorded. For fiscal 1995 the provision for income taxes was
10% of pre-tax income.
 
  YEARS ENDED JUNE 30, 1995, 1994 AND 1993
 
  Net Sales
 
     Net sales for fiscal 1995 increased to $126.9 million from $105.6 million
in fiscal 1994 and $25.1 million in fiscal 1993 as a result of increased unit
shipments. Fiscal 1994 results include a full year of commercial shipments of
the Cadence V-100 system, while the previous fiscal year included only two
months of such commercial sales. Sales of defibrillator systems provide
substantially all of the Company's revenues. During fiscal 1995 and 1994, a
substantial majority of the Company's sales were to hospitals at the request of
physicians who used Cadence defibrillators in combination with a competitor's
transvenous defibrillation lead system. In October 1994, the Company received
regulatory approval authorizing expanded labeling of Cadence defibrillators for
use with CPI's Endotak 60 and 70 series transvenous lead systems. Sales in the
fourth quarter of 1995 decreased significantly from prior quarters as a result
of the availability of competitive defibrillators capable of being implanted
pectorally.

  Gross Profit
 
     Gross profit for fiscal 1995 increased to $71.0 million from $59.7 million
in 1994 and $8.1 million in 1993. The increase in gross profit from fiscal 1994
to fiscal 1995 was primarily due to increases in sales volume and lower per-unit
component costs, partially offset by an increase in royalty expenses under
patent cross-license agreements, increased spending to establish leads
manufacturing capabilities, and increased provisions for product obsolescence.
 
     Gross margin (gross profit as a percent of net sales) was 55.9%, 56.5% and
32.2% for fiscal years 1995, 1994 and 1993, respectively. Gross margins in all
three fiscal years were adversely affected by the impact of increased inventory
reserves, reflecting new product introductions by the Company and its
competitors and other factors. Gross margin in the fourth quarter of fiscal 1995
was 50.1%, compared with 56.9% for the first nine months of the fiscal year,
largely due to a substantial decline in net sales from the prior quarters as a
result of the competitive pressures described above.
 
  Operating Expenses
 
     Operating expenses were $64.2 million in fiscal 1995 compared to $52.3
million in fiscal 1994 and $44.5 million in fiscal 1993. Fiscal 1993 operating
expenses included a charge of $18.6 million relating to intellectual property
settlements.
 
     Research and development expenses increased approximately 19% to $27.7
million in fiscal 1995, compared to $23.3 million in fiscal 1994 and $12.9
million in fiscal 1993. Growth in research and development expenses throughout
this period reflects substantial increases in the number of regular employees,
consultants and contract employees engaged in research and product and process
development activities. In fiscal 1995, spending on materials and parts used in
development activities, primarily for defibrillators, increased significantly
over fiscal 1994 levels.
 
     Selling, general and administrative expenses increased to $36.5 million in
fiscal 1995 from $28.9 million in fiscal 1994 and $13.0 million in fiscal 1993.
As a percentage of net sales, selling, general and administrative expenses were
29%, 27% and 52% for fiscal years 1995, 1994 and 1993, respectively. The
increases in spending reflect increased staffing and associated expenses,
amortization of costs of external equipment to program defibrillators (which are
supplied to customers on long-term loan, typically at no charge, in accordance
with industry practice), costs incurred to implement a new software system,
research grants and donations, insurance, and costs related to unit sales volume
increases. Legal expenses were approximately the same in fiscal years 1995, 1994
and 1993.
 
  Other Income
 
     Interest income was $3.4 million, $1.5 million, and $1.9 million in fiscal
years 1995, 1994 and 1993, respectively. Fluctuations in interest income reflect
changes in interest rates and cash balances during this period. Included in
other income in fiscal 1993 is $1.4 million representing reimbursement of prior
legal expenses as part of an insurance settlement.
 
  Income Taxes
 
     The provision for income taxes was 10% of pre-tax income in fiscal 1995; no
provision was recorded in fiscal 1994 or fiscal 1993. The provision for income
taxes in fiscal 1995 reflects the benefit from the utilization of tax net
operating loss carryforwards.
 
FLUCTUATIONS IN QUARTERLY RESULTS
 
     The Company's results of operations have varied, may continue to fluctuate
significantly from quarter to quarter, and will depend upon numerous factors
including: timing of regulatory approvals, market acceptance of the Company's
products, introductions of new products with advanced features by the Company or
its competitors, technological advances in the treatment of arrhythmias, outcome
of intellectual property litigation, competition and component part
availability. The Company's gross
 
                                       20
<PAGE>   22
 
margins will be dependent on production volume, manufacturing efficiencies,
product obsolescence, competitive pricing, royalties under patent license
agreements, component price fluctuations, varying product sales mix, warranty
expense and other factors. The Company's future operating results may fluctuate
as a result of these and other factors, including seasonality and health care
reimbursement policies.
 
     The Company typically manufactures to its internal sales forecast, fills
orders as received, and has no significant backlog of orders for its products.
In addition, major components of the Company's defibrillator systems require
firm purchase commitments (which may not be cancelable) well in advance of the
anticipated delivery of such components. As a result, failure to accurately
anticipate future demand may result in substantial excess inventory, significant
cancellation costs for purchase commitments, or inability to meet demand for the
Company's products and could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
     A significant portion of the Company's operating expenses are relatively
fixed, and planned expenditures are based primarily on sales forecasts and
product development programs. If sales do not meet the Company's expectations in
any given period, the adverse impact on operating results may be magnified by
the Company's inability to adjust operating expenditures quickly enough to
compensate for such a shortfall. The Company's net sales decreased significantly
in the fourth quarter of fiscal 1995 due to the commercial availability of
competitive defibrillator systems, decreased further in the first two quarters
of fiscal 1996 and did not increase significantly in the third quarter of fiscal
1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Cash and equivalents and short-term investments totaled $37.7 million at
March 31, 1996, compared to $73.9 million at June 30, 1995. The decrease of
$36.2 million reflects cash used in operations of $30.4 million during the nine
months ended March 31, 1996, and investments in capital equipment and leasehold
improvements of $6.9 million partially offset by proceeds from exercise of stock
options and an employee stock purchase plan of $1.4 million. Cash used in
operations during the nine months ended March 31, 1996 includes the net loss of
$49.2 million partially offset by reductions in accounts receivable of $3.9
million, reflecting a decrease in quarterly sales from the fourth quarter of
fiscal 1995, and reductions in inventory of $6.1 million, reflecting additional
provisions for potentially excess inventory.
 
     In view of current and anticipated capacity requirements, the Company
anticipates capital expenditures of approximately $6.0 million in fiscal 1997,
as compared with $13.4 million in fiscal 1995 and approximately $9.0 million in
fiscal 1996. Fiscal 1997 capital expenditures are expected to be made
principally in connection with the purchase of new equipment.
 
     The Company believes that the proceeds of this offering, together with
current cash balances, will be sufficient to meet the Company's foreseeable
capital requirements. However, Ventritex may use debt or other means of
financing when deemed necessary and/or financially advantageous. The Company's
liquidity and capital requirements will depend upon numerous factors, including
the extent to which the Company's future products gain market acceptance, the
duration and magnitude of operating losses, FDA regulatory actions, changes in
health care reimbursement policies, and intellectual property litigation to
which the Company is or may become a party.
 
                                    BUSINESS
 
THE COMPANY
 
     Ventritex designs, develops, manufactures and sells implantable
defibrillators and related products for the treatment of ventricular tachycardia
and ventricular fibrillation. Ventricular tachycardia and ventricular
fibrillation are the most serious and life-threatening forms of abnormal heart
rhythms ("arrhythmias"). The Company's principal product, the Cadet V-115
implantable defibrillator, is an electronic device that is implanted in the
patient's pectoral (chest) or abdominal region and is connected
 
                                       21
<PAGE>   23
 
to the patient's heart with defibrillation leads, which are typically implanted
transvenously. The Cadet V-115 is the successor to the Company's Cadence V-100
and V-110 implantable defibrillators, which are considerably larger than the
Cadet V-115 and are implanted in the patient's abdominal region. The Cadet has
the same functional and performance characteristics as larger Ventritex
defibrillators and offers features, including high defibrillation energy output
and extended electrogram ("EGM") storage, superior to competing defibrillators
that can be implanted pectorally. As of June 30, 1996, approximately 1,000 Cadet
and 17,250 Cadence implants had been performed at over 550 sites. The Company's
defibrillators monitor the heartbeat and deliver electrical pulses or shocks to
the heart to terminate ventricular tachycardia and ventricular fibrillation in
patients. In ventricular tachycardia, the heart's ventricles contract at an
abnormally rapid rate and typically deliver less blood to the body's tissues and
organs. Episodes of ventricular tachycardia occur unpredictably and can progress
to ventricular fibrillation. In ventricular fibrillation, the heart's normal
electrical impulses become disorganized and erratic and the heart ceases to pump
blood. If ventricular fibrillation is not terminated quickly, the individual
will experience a sudden cardiac death ("SCD") episode during which the
individual will become unconscious and, without prompt medical intervention,
typically will die.
 
BACKGROUND
 
     The heart is divided into four chambers, two upper chambers called atria
and two lower chambers called ventricles. The heart's function is to pump blood
through the body's circulatory system. Each normal heartbeat is the result of
electrical signals generated at a precise area in the right atrium, called the
sino-atrial node, the heart's natural pacemaker. These electrical signals cause
a physical contraction of the atria, which pump blood into the ventricles. The
electrical impulses then continue to the ventricles, causing them to contract
and distribute blood throughout the body.
 
     Arrhythmias, abnormal rhythms of the heart muscle, arise from numerous
causes, including tissue damage due to previous heart attacks, congenital
defects and certain diseases. Arrhythmias originate in either the atria, where
they are generally not life-threatening, or the ventricles, where they can
significantly interfere with the pumping of oxygenated blood and can therefore
be life-threatening. During an arrhythmia, the heart beats either too slowly or
too rapidly. An abnormally slow heart rate, generally defined as a heart rate
below 50 beats per minute, is known as bradycardia. Ventricular tachycardia, a
more serious arrhythmia, occurs when abnormal electrical signals occur in the
ventricles, causing the ventricles to beat at an abnormally rapid rate. When the
ventricles beat at an abnormally rapid rate, they do not have sufficient time to
fill with blood prior to each contraction and therefore less blood is pumped out
of the heart. As a result, less oxygen is carried to the tissues and organs of
the body. This lack of oxygen can cause dizziness, unconsciousness, cardiac
arrest and, ultimately, death.
 
     Patients experiencing heart problems are usually treated initially by
cardiologists. Cardiologists may refer patients with ventricular
tachyarrhythmias to specialists in electrophysiology, a cardiology subspecialty
requiring extensive, advanced training in the diagnosis and treatment of
arrhythmias. Typically, an electrophysiologist will conduct extensive testing to
determine the appropriate therapy, including testing various drugs to determine
their potential for preventing future spontaneous tachyarrhythmias.
Electrophysiology testing is a costly procedure and often requires
hospitalization. If an antiarrhythmic drug is successful in these tests, the
drug will usually be prescribed for the patient. If an appropriate drug cannot
be identified, or if the patient's ventricular tachyarrhythmia is judged to be
too critical to be treated by drugs alone, the electrophysiologist will
typically elect to implant a defibrillator.
 
MARKET
 
  UNITED STATES
 
     Since the first defibrillator implant in 1981, the Company estimates that
through 1995 over 90,000 defibrillators had been implanted in the United States,
including approximately 22,000 in 1995. Implantable defibrillators are generally
purchased by hospitals upon the recommendation of electrophysiologists.
Currently, approximately 1,200 electrophysiologists practice at medical centers
in the United
 
                                       22
<PAGE>   24
 
States where defibrillator implants are performed. Today, many individuals in
the United States who are at high risk of experiencing an SCD episode are not
referred to electrophysiologists for diagnosis and treatment. The Company
believes that referrals to electrophysiologists have been increasing annually as
physicians have become more aware of the benefits of electrophysiology testing.
Medical studies suggest that individuals at high risk of SCD who are not
referred to electrophysiologists have a significantly higher mortality rate from
SCD because such individuals receive unguided drug therapy that is less
effective than the therapy received by those individuals who are referred to an
electrophysiologist.
 
     Recently, a clinical study sponsored by a competing manufacturer of
implantable defibrillators demonstrated the clinical utility of implanting
defibrillators in additional classes of patients that are at high risk of an SCD
episode. In particular, this study demonstrated the utility of implanting
defibrillators in patients who have suffered a heart attack and are at high risk
of an SCD episode but who do not exhibit other symptoms, such as sustained
ventricular tachycardia. As a result of this study, the sponsoring manufacturer
has been permitted by the FDA to expand the labeling of its device to include
this class of patients. The Company is seeking FDA approval of a PMA supplement
to similarly expand the labeling of its implantable defibrillators. Although
there can be no assurance as to the action the FDA will take in this regard, a
broadening of the classes of patients that can receive defibrillator implants
could result in an increased market for defibrillators.
 
  INTERNATIONAL
 
     To date, the United States market has represented approximately 80% of the
world market for implantable defibrillators. The international market for
implantable defibrillators has been constrained by the lack of effective
emergency medical services in many developed countries. However, certain
international markets, including particularly Germany and Italy, represent
attractive markets for implantable defibrillators, and, to the extent that
emergency medical services in other countries improve, the market for
implantable defibrillators in these countries could correspondingly grow.
 
IMPLANTABLE DEFIBRILLATORS
 
     An implantable defibrillator is an electronic device that is implanted in
the patient and is designed to monitor the patient's heartbeat and deliver
electric pulses or shocks to the heart to terminate ventricular
tachyarrhythmias. The limitations of first and second generation implantable
defibrillators led to the development of third-generation defibrillators capable
of providing tiered therapy. Tiered therapy defibrillators are designed to
provide three types of therapy: (i) low voltage electrical pacing pulses to
terminate ventricular tachycardia, (ii) one or more cardioversion shocks to
convert, to a normal rhythm, ventricular tachycardia that cannot be controlled
through antitachycardia pacing, and (iii) high-energy defibrillation shocks to
terminate ventricular fibrillation. Third-generation implantable defibrillators
also provide greater programmability to increase the physician's ability to
customize therapy to a patient's condition during and after implant. The
Company's Cadence V-100 defibrillator and a competitor's third-generation,
tiered therapy implantable defibrillator received PMA approval in 1993. The
Cadence V-100 was the first third-generation, tiered therapy implantable
defibrillator incorporating both electrogram ("EGM") storage and a biphasic
defibrillation waveform to receive regulatory approval. The Company's Cadence
V-110 implantable defibrillator, a smaller version of the V-100 with similar
performance characteristics, and a competitor's third-generation defibrillator
received regulatory approval in 1994.
 
     Competition in the market for tiered therapy implantable defibrillators
increased significantly in March 1995 with FDA approval of a PMA application for
implantable defibrillators manufactured by two of the Company's competitors, CPI
and Medtronic, which allowed implantation in the pectoral area, rather than the
abdominal area, in suitable patients. The ability to implant the defibrillator
pectorally enables the implant procedure to be performed by an
electrophysiologist alone, rather than in conjunction with a surgeon. In May
1996, the Company received FDA approval for pectoral implantation labeling of
the Cadet V-115 implantable defibrillator. The Cadet V-115 is comparable in size
to the new defibrillators introduced by CPI and Medtronic.

<PAGE>   25
 
TRANSVENOUS LEAD SYSTEMS
 
     Since the United States commercial introduction of transvenous
defibrillation leads in 1994, transvenous lead systems, in which the
defibrillation leads are implanted through a vein to connect the defibrillator
with the heart, have become the preferred type of lead system.
 
     Defibrillation lead systems require two electrodes to deliver electrical
energy to the heart. Defibrillation lead systems can be configured with two
leads, in which case a single electrode will be placed on each lead. In
addition, two single lead configurations are possible. In one such
configuration, two electrodes are placed on a single lead. Alternatively, in a
configuration known as a "high voltage can," one or two electrodes are placed on
the lead and the housing of the defibrillator unit serves as the second or third
electrode. Certain physicians may have a preference for single lead systems
because of their belief that a single lead system is easier to implant. However,
the Company estimates that, as compared to a single lead system, a dual lead
system requires approximately five additional minutes to implant and offers
additional flexibility in electrode configuration.
 
     In May 1996, the Company received FDA approval of a PMA application for its
TVL transvenous defibrillation lead system. The TVL is configured as a dual lead
system. The Company is currently engaged in clinical trials of two single lead
systems, one in which both electrodes are on a single lead and a second with a
single electrode on the lead and another on a high voltage can version of the
Cadet V-115 defibrillator. There can be no assurance as to when or whether the
Company will receive PMA approval for such single lead systems.
 
     To date, a large percentage of the Company's sales of defibrillators have
been at the direction of physicians who used the Company's defibrillators in
combination with commercially available transvenous lead systems supplied by the
Company's competitors. Therefore, there can be no assurance that physicians will
purchase transvenous lead systems for which the Company obtains regulatory
approval. In particular, physicians preferring single lead systems may choose to
continue to combine competitors' transvenous leads with the Company's
defibrillators, at least until such time as the Company obtains PMA approval for
its single lead systems. Furthermore, there can be no assurance that
manufacturers of competing transvenous lead systems will not attempt to
discourage or prevent use of their leads with the Company's defibrillators
through product labeling, availability, pricing or other means. In general,
unless the FDA-approved labeling includes use with any transvenous lead system
sold by its competitors, the FDA or other government agencies may take further
actions, including restrictions on reimbursement, to restrict the combination of
the Company's defibrillators with such transvenous lead systems. Such actions
could make the Company's defibrillators, including both the Cadet and the
Contour, less attractive to physicians and could therefore have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
PRODUCTS
 
     The Cadet implantable defibrillator system consists of a Cadet
microprocessor-based implantable defibrillator; sensing/pacing and
defibrillation leads that connect the Cadet defibrillator to the patient's
heart; the Programmer, a customized personal computer that the
electrophysiologist uses to program the defibrillator's operating parameters
during and after the implant and to retrieve information from the device after
implant; and the High Voltage Stimulator ("HVS-02") that the electrophysiologist
may use during the implant procedure to ensure proper placement of the leads, to
determine the level of energy needed to defibrillate the patient, and to perform
testing before implanting the Cadet defibrillator.
 
  CADET V-115 DEFIBRILLATOR
 
     The Company's principal product, the Cadet V-115 implantable defibrillator,
is a third-generation, tiered therapy implantable defibrillator that uses a
sophisticated sensing system to continuously monitor the patient's heart rate
and employs a complex set of algorithms to distinguish various types of
ventricular arrhythmias. The tiered therapy Cadet system may be programmed to
initially deliver low voltage antitachycardia pacing designed to control
ventricular tachycardias that can be terminated by
 
                                       24
<PAGE>   26
 
such pacing. The Cadet can also be programmed to deliver cardioversion shocks in
an attempt to convert ventricular tachycardia to a normal rhythm, or deliver one
or more high energy electric shocks to the heart to terminate ventricular
fibrillation. Cadet defibrillators are programmed by the physician upon implant
and periodically thereafter to respond to a patient's changing needs.
 
     A Cadet defibrillator, configured for use with a Ventritex lead system, is
73 cubic centimeters in size and has been designed to be small enough to be
implanted in the pectoral region while delivering the same functional and
performance characteristics as larger tiered therapy implantable defibrillators
that must be implanted in the abdomen. Key features of the Cadet include the
following:
 
     -  High Defibrillation Energy Output.  The Cadet delivers energy output up
       to approximately 38 joules, which is more than other pectorally
       implantable defibrillators that are commercially available or, to the
       Company's knowledge, in clinical trials in the United States. Since
       certain patients require a high level of energy output to terminate
       ventricular fibrillation, the Cadet's high power output can expand the
       range of patients who can be effectively treated as well as providing an
       additional safety margin.
 
     -  Programmability.  Cadet defibrillators are configured to provide the
       electrophysiologist with the ability to vary the operating parameters of
       implanted units using the Programmer. This programmability allows the
       physician to customize therapy to the patient's condition during and
       after implant. The Programmer is menu-driven and features a touch screen
       interface to simplify device programming and information retrieval.
 
     -  Biphasic Defibrillation Waveform.  Cadet defibrillators can deliver
       electrical shocks to the patient in a monophasic or biphasic waveform.
       Clinical studies suggest that biphasic waveforms achieve improved
       defibrillation efficacy compared to monophasic waveforms.
 
     -  Electrogram Storage.  Cadet defibrillators continuously collect data to
       record information on the patient's arrhythmic events in EGM form. This
       feature provides valuable information that enables the
       electrophysiologist to analyze spontaneous arrhythmic events that the
       patient has experienced, to evaluate the effectiveness of therapies that
       were delivered in response to arrhythmic events and, if appropriate, to
       adjust operating parameters of the device. The Cadet provides up to 8
       minutes of EGM storage. The continuous EGM storage provided by the Cadet,
       as compared to the segmented EGM data provided by certain competing
       defibrillators, improves the quality of EGM data available to the
       electrophysiologist for arrhythmia diagnosis.
 
     -  Continuous Sensing and Non-Committed Therapy.  Cadet defibrillators
       continuously sense the heart's activity while the defibrillator is
       charging its high voltage capacitors to the level required for the
       indicated therapy, and can abort the charging process if the patient's
       heart function spontaneously returns to normal. This feature is
       significant because the Cadet defibrillator does not subject the patient
       to unnecessary and painful electric shocks if the patient's heart
       function spontaneously returns to normal.
 
     -  Backup Bradycardia Pacing.  Cadet defibrillators can provide pacing to
       correct an abnormally slow heartbeat. This pacing is sometimes necessary
       to restart a patient's heart following a defibrillation shock. This
       feature reduces the need to implant a second device for those patients
       who would otherwise require a bradycardia pacemaker.
 
     Cadet defibrillators are constructed as one-piece, hermetically sealed
units which contain hybrid circuits, high voltage capacitors and batteries.
Hybrid circuits include custom VLSI circuits, a semi-custom microprocessor and
memory chips. The hybrid circuits process and store data and control the
operation of the Cadet units. The capacitors accumulate an electric charge and
deliver high voltage shocks. The Cadet implantable defibrillator is
battery-powered and is designed to have a life of three to five years, although
battery life varies depending on the frequency and duration of pacing and the
number of times the capacitors are charged to high voltage. The list price for
the Cadet V-115, without leads, is approximately $20,000.

<PAGE>   27
 
  CONTOUR V-145 DEFIBRILLATOR
 
     To date, a limited number of Contour V-145 implantable defibrillators have
been implanted in patients in Europe. At 57 cubic centimeters, the Contour is
one of the smallest third-generation implantable defibrillators. The Contour
offers the same high, approximately 38 joule energy output provided by the Cadet
and provides 16 minutes of stored EGM data. In June 1996, the Company submitted
a PMA supplement for the Contour to the FDA; however, there can be no assurance
that the FDA will accept this submission as a PMA supplement. The FDA could
instead require additional testing of the Contour and could also require
clinical data in order to approve the supplement. The Company would then be
required to conduct additional clinical trials under an IDE and submit data from
such trials. This could result in significant delays in approval for the
Contour. Delays in receiving or failure to receive PMA approval for the Contour
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
  TVL TRANSVENOUS LEAD SYSTEM
 
     The Company's principal lead system which is labeled for use with Cadet
defibrillators is the TVL transvenous lead system. The Company received
regulatory approval for the TVL system in May 1996. The TVL system employs a
dual lead configuration. The TVL leads are designed to offer the flexibility and
maneuverability of pacemaker leads, which have been implanted transvenously for
many years, making them easy to handle and place in the patient. TVL leads
provide sensing and pacing and are used to monitor heart function and to deliver
antitachycardia or bradycardia pacing, as needed. The current list price of the
TVL system is approximately $5,500.
 
  NEW SINGLE LEAD SYSTEMS
 
     The Company has developed and is conducting clinical trials of two single
lead systems to provide additional flexibility for electrophysiologists in
selecting a lead system and to accommodate the preferences of many
electrophysiologists for a single lead system. The Company's SPL system is a
single lead with two defibrillation electrodes. The Company is also conducting
clinical trials of a "high voltage can" version of the Cadet V-115. In this
system, one electrode is on the lead and the housing of the Cadet, which is made
of titanium, serves as the other electrode. The Company intends to submit PMA
supplements for the SPL system and the high voltage can version of the Cadet to
the FDA. There can, however, be no assurance that the FDA will accept these
submissions as PMA supplements. The FDA could instead require additional testing
of or modification to the SPL or the Company's high voltage can defibrillator
and could also require clinical trials under an IDE and completion of the entire
PMA approval process, as opposed to the typically shorter PMA supplement
process. Delays in receiving or failure to receive PMA approval for the SPL or
the high voltage can defibrillator could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
  PROGRAMMER
 
     Ventritex Programmers are customized personal computers that provide
communication with the Company's defibrillators using a specialized
communication wand. This feature allows the physician to alter the operating
parameters of Cadet defibrillators, to receive and display diagnostic data and
to non-invasively induce ventricular tachycardia or fibrillation in the patient
to periodically evaluate the patient's defibrillation threshold and
defibrillator performance. The Programmer is menu driven and uses a color touch
screen to highlight programming steps and changes, which simplifies the setup
and monitoring of defibrillator operating parameters. The Company typically
provides Programmers without charge for each domestic site implanting the
Company's defibrillators. As a result, the Company anticipates expensing
approximately $6 million during fiscal 1997 for Programmers and HVS-02 high
voltage stimulators provided to hospitals and other sites where the Company's
defibrillators are implanted.
 
                                       26
<PAGE>   28
 
  HIGH VOLTAGE STIMULATOR
 
     The HVS-02 high voltage stimulator is an external device that may be used
by the electrophysiologist during the implant procedure to facilitate proper
placement of the leads and to induce and terminate ventricular tachycardia or
fibrillation to determine the energy required to defibrillate the patient. It
provides an external defibrillator to determine defibrillation thresholds, a
pacing system analyzer to properly position the sensing/pacing leads, and a
programmable stimulator to induce either ventricular tachycardia or
fibrillation. Typically, one HVS-02 is used at each institution implanting the
Company's defibrillators and HVS-02 devices are typically provided by the
Company without charge. However, it is also possible to have the defibrillator
itself perform the functions of the HVS-02 during the implant procedure, and an
increasing number of implants are currently being performed without use of the
HVS-02.
 
RESEARCH AND DEVELOPMENT
 
     The Company's research and development efforts include various research,
product and process development, clinical trial and quality assurance
activities. These activities are performed by the Company's staff and are
supplemented by work conducted on the Company's behalf by outside sources. The
Company is engaged in research and development projects for future defibrillator
systems, transvenous defibrillation lead systems and external equipment. Delays
in development of new products by Ventritex or developments involving
competitors, including commencement of clinical trials or commercialization of
new implantable devices, pharmaceuticals, cardiac ablation or surgical
alternatives for the treatment of ventricular tachycardia or ventricular
fibrillation, could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     Research and development expense was $27.7 million, $23.3 million and $12.9
million for fiscal years 1995, 1994 and 1993, respectively. The Company expects
research and development expense to continue to increase in dollar amount in the
future.
 
     Market acceptance and sales of the Company's products could be adversely
affected by technological changes. Many companies with substantially greater
resources than the Company are engaged in the development of products and
approaches for the treatment of ventricular tachycardia and ventricular
fibrillation. These include implantable devices as well as pharmaceuticals and
cardiac ablation therapies. Future innovations in the treatment of ventricular
tachycardia and ventricular fibrillation could render existing technologies,
including the Company's systems, less competitive or obsolete.
 
CLINICAL ENGINEERING, MARKETING AND SALES
 
     The Company's skilled sales, marketing, clinical engineering and support
staff consult with electrophysiologists on the features and applications of the
Company's products. In addition, sales and field clinical engineering personnel
conduct ongoing training sessions and provide clinical support by attending
defibrillator implants and patient follow-up sessions.
 
     The Company's field sales and field clinical engineering organizations
currently include approximately 60 individuals. The field organization enables
the Company to focus its marketing program on electrophysiology centers in the
United States. In addition, the Company is addressing international markets,
typically through specialty cardiovascular product distributors. During fiscal
1996, the Company established a direct sales and field clinical engineering
organization in Germany.
 
     No customer accounted for more than 10% of net sales in any of fiscal years
1995, 1994 or 1993.
 
MANUFACTURING
 
     The Company's manufacturing facility based in Sunnyvale, California
contains assembly areas where its products are assembled and tested. The
manufacturing area includes controlled environment rooms in which certain lead
systems are manufactured, and the completed defibrillators and lead systems are
packaged before being sent to an outside sterilization facility. The Company's
quality assurance group
 
                                       27
<PAGE>   29
 
performs tests at various steps in the manufacturing cycle to ensure compliance
with the Company's specifications.
 
     The Company relies on outside suppliers to manufacture certain major
components of its defibrillator systems. The Company currently has sole source
supply arrangements with its suppliers of hybrid circuits, high voltage
capacitors, integrated circuits, defibrillation lead components, batteries and
certain other components used in its products. For certain components, there are
relatively few potential sources of supply and establishment of additional or
replacement suppliers for these components cannot be accomplished quickly. The
Company believes that alternative sources of supply are available for most
components and subcontracted manufacturing services, and plans to qualify
additional suppliers as production volumes increase. Because of the long lead
times for some components that are currently available from only a single
source, a vendor's inability to supply acceptable components in the quantity
required could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
     During the first half of fiscal 1996, in anticipation of regulatory
approval, the Company began production of its Cadet V-115 defibrillator system
and TVL transvenous lead system, and initially experienced shortages of certain
critical components due to manufacturing yield problems at its suppliers. There
can be no assurance that future production problems will not be encountered in
production of the Company's current or future products. Failure to manufacture
new or existing products on a timely and cost effective basis could result in
substantial unanticipated expenses, delays in the commercial availability of
such products, and could have a material adverse affect on the Company's
business, financial condition and results of operations.
 
PRODUCT WARRANTY
 
     The Company's implantable defibrillator systems include a complex
electronic device and leads designed to be implanted in the human body for long
periods of time. Component failures, manufacturing errors or design defects
could result in an unsafe condition, injury or death to the patient. The
occurrence of such a problem could result in a recall of the Company's products,
explanting implanted defibrillators or leads and the implanting of new
defibrillators or leads.
 
     The Company's defibrillators are warranted for the earlier of three years
or 100 high voltage capacitor charges, assuming nominal pacing during the time
the unit is implanted. Previously, the Company experienced certain component
failures with the Cadence defibrillator and with lead systems. For example,
during clinical trials, a number of Cadence V-100 defibrillators experienced
premature battery depletion due to defective capacitors supplied by an outside
vendor. In all these instances, the devices were explanted and replaced with new
defibrillators. The Company has experienced what it believes, in light of
industry experience, to be a typical level of returns of defibrillator units
from the field for various reasons, none of which the Company believes are
systemic or would otherwise give rise to a product recall. There can, however,
be no assurance that the Company's products will not experience additional
performance difficulties. Future product problems resulting in a recall could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
     The manufacture and sale of the Company's products entails the risk of
product liability claims. Although the Company maintains product liability
insurance with coverage limits of $25.0 million per occurrence and $25.0 million
in the aggregate per year, there can be no assurance that the coverage limits of
the Company's insurance policies will be adequate. Product liability insurance
is expensive and may not be available in the future on acceptable terms or at
all. In addition, the Company has indemnified certain of its component suppliers
for certain potential product liability. To date, the Company has not
experienced any material product liability claims. A successful claim brought
against the Company in excess of its insurance coverage could have a material
adverse effect on the Company's business, financial condition and results of
operations and could adversely affect the Company's ability to continue as a
viable entity. Also, as a result of the June 1996 United States Supreme Court
decision in Medtronic, Inc. v. Lohr, which rejected federal pre-emption of
certain state law causes of action in relation to medical
 
                                       28
<PAGE>   30
 
devices, the Company expects that product liability claims relating to medical
devices may be pursued more aggressively in the future.
 
COMPETITION
 
     Competition in the market for implantable defibrillator systems is intense.
Although patients susceptible to ventricular tachycardia and ventricular
fibrillation may be treated with antiarrhythmic drugs or cardiac ablation
therapies, the Company believes that manufacturers of implantable defibrillators
are its primary competitors. The Company's principal competitors are CPI and
Medtronic. Both CPI and Medtronic are large, diversified cardiology and medical
device companies and each has invested substantial amounts in implantable
defibrillator research and development. Other competitors in the implantable
defibrillator market include Telectronics, Intermedics and Angeion Corporation.
 
     In March 1995, the FDA approved the commercial release of new
defibrillators manufactured by CPI and Medtronic which are small enough to allow
pectoral implantation, rather than abdominal implantation, in suitable patients.
Until receipt of regulatory approval relating to the Cadet in May 1996, the
Company could not offer an implantable defibrillator labeled for pectoral
implantation in patients in the United States. Commercial release of pectorally
implantable defibrillators significantly increased competition in the
implantable defibrillator market and resulted in a significant decline in the
Company's market share and sales of the Company's products. The Company now has
products which it believes are competitive; however, there can be no assurance
that the Company's products will compete successfully with products currently
manufactured by others or future products under development by competitors which
have new features, such as dual chamber and rate-responsive pacing capabilities.
 
     Medtronic and CPI have regulatory approval of and are commercially
marketing single lead transvenous lead systems. The Company currently is
marketing the TVL transvenous lead system, a dual lead system. Some physicians
prefer a single lead system due to the perceived ease of implanting such a
system as compared to a dual lead system. The Company is engaged in clinical
trials of single lead transvenous defibrillation lead systems and must receive
PMA approval prior to commercialization. There can be no assurance as to when or
whether the Company will receive PMA approval for these systems.
 
     Many of the Company's competitors, including both CPI and Medtronic, have
substantially greater financial, manufacturing, marketing and technical
resources than those of the Company. The financial resources of certain of the
Company's competitors may enable them to use pricing pressures as a means of
competition. In addition, competitors have in the past and may in the future
employ litigation to gain a competitive advantage. There can be no assurance
that the Company's competitors will not develop or obtain regulatory approval
for implantable defibrillation systems, or for pharmaceuticals or surgical
alternatives, that may be more effective in treating ventricular tachycardia and
ventricular fibrillation than the Company's current or future products, or that
the Company's technologies and products would not be rendered less competitive
or obsolete by such developments. Failure of the Company's products to gain
market acceptance or limited growth in the market for implantable defibrillators
would have a material adverse effect on the Company's business, financial
condition and results of operations.
 
     Any product developed by the Company that gains regulatory approval will
have to compete for market acceptance and market share. An important factor in
such competition may be the timing of market introduction of competitive
products. Accordingly, the relative speed with which the Company can develop
products, complete clinical testing and regulatory approval processes and supply
commercial quantities of the product to the market is expected to be a critical
competitive factor. The Company expects that competition will also be based,
among other things, on the ability to safely and effectively treat ventricular
tachycardia and ventricular fibrillation, the availability of defibrillation
systems that can be implanted through less invasive surgical procedures, ease of
programmability, ability to provide improved diagnostic capability, size and
weight of the device, product reliability, physician familiarity with the
device, patent position, sales and marketing capability, third-party
reimbursement policies, reputation and price.
 
                                       29
<PAGE>   31
 
     In addition, the Company is aware that competitors are developing and, in
some instances, are conducting clinical trials of implantable defibrillators
that have features not included in the Company's defibrillators. Moreover, these
competitors may obtain expedited regulatory approval from the FDA for these new
devices. Commercial release of competitors' products with features not available
in the Company's products could have a material adverse effect on the Company's
business, financial condition and results of operations.
 
THIRD PARTY REIMBURSEMENT
 
     Implantable defibrillators are generally purchased by hospitals upon
recommendations of electrophysiologists. Typically, these hospitals then bill
various third party payors for the health care services provided to their
patients. These payors include Medicare, Medicaid and private insurers.
Government agencies reimburse hospitals for medical procedures at rates based
upon Diagnostic-Related Groups ("DRGs").
 
     Third party payors are increasingly challenging the prices charged for
medical products and services, and current levels of reimbursement may be a
disincentive to some hospitals to perform defibrillator implants. Currently, the
sales prices of implantable defibrillators range from approximately $12,000 to
$20,000, excluding leads. According to an industry study published in January
1995, a defibrillator implant procedure, excluding electrophysiology testing,
typically costs between $30,000 and $60,000, depending on the length of hospital
stay and other variables. The same source indicated that the average Medicare
reimbursement for an initial defibrillator implant procedure is approximately
$35,000 to $40,000 and that the average Medicare reimbursement for defibrillator
replacement procedures is approximately $20,000. Consequently, despite the
Company's receipt of regulatory approvals for its systems, third party payors
may deny full reimbursement. There can be no assurance that the Company's
implantable defibrillator systems will be considered cost effective by third
party payors, that reimbursement will be available, or if reimbursement is
available, that third party payors' reimbursement policies will not adversely
affect the Company's ability to sell its products on a profitable basis. The
failure by hospitals and other users of the Company's products to obtain
reimbursement from third party payors could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
     In addition, legislative initiatives relating to health care reform have
been introduced in Congress and certain state legislatures. These initiatives
have been focused, in large part, on health care cost containment. Such
initiatives, if enacted, could adversely affect the availability of third party
reimbursement for the Company's products and the price levels at which the
Company is able to sell its products. The Company's business, financial
condition and results of operations could be adversely affected by changes in
government and private payors' reimbursement policies relating to procedures
using the Company's products.
 
     Medicare and Medicaid policies currently permit reimbursement for
investigational medical devices if such devices represent evolutionary
modifications to commercially available products. Under this policy, for
example, next generation implantable defibrillators in clinical trials would be
eligible for reimbursement because these devices are derived from an existing,
approved class of products. Because the Company anticipates that it will be
required to conduct clinical trials in connection with future products, changes
in this reimbursement policy could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business -- Third Party Reimbursement."
 
PATENTS AND PROPRIETARY RIGHTS
 
     The Company files patent applications to protect technology and inventions
that are significant to the development of its business. As of June 30, 1996,
the Company held 71 issued United States patents and 11 issued foreign patents
and had pending 51 United States and 28 corresponding foreign patent
applications that cover various aspects of its technology. The Company's issued
United States patents expire on dates ranging from 2006 through 2014. There can
be no assurance that any of the claims in the
 
                                       30
<PAGE>   32
 
pending patent applications will be allowed, or that any issued patents will be
upheld, or not circumvented by competitors, or that any patents or licenses will
provide competitive advantages for the Company's products. The Company also
relies on trade secrets and proprietary know-how which it seeks to protect, in
part, through confidentiality agreements with employees, consultants and other
parties. There can be no assurance that these agreements will not be breached,
that the Company will have adequate remedies for any breach, or that the
Company's trade secrets will not otherwise become known to or independently
developed by competitors.
 
     The segment of the medical device market that includes implantable
defibrillators has been characterized by extensive litigation regarding patents
and other intellectual property rights. The Company has resolved intellectual
property disputes to date through licensing arrangements, when appropriate and
on terms it believes to be commercially reasonable. Under certain agreements,
the Company pays royalties based on commercial sales of implantable
defibrillator systems. The Company anticipates that such royalties will continue
for future implantable defibrillator systems developed by the Company.
Additionally, the agreements do not include all patents that may be issued to
the licensors, thus future patent disputes with these companies are possible.
Intermedics has filed claims against the Company for patent infringement which
are still pending, and there can be no assurance that other parties will not
institute additional litigation against the Company.
 
     In 1990, two of the Company's competitors, Telectronics and Intermedics,
instituted patent infringement litigation against the Company. Medtronic and CPI
also notified the Company that they believed the Company infringed patents held
by them. In May 1992, the Company and Medtronic agreed to cross-license their
respective patent portfolios relating to devices for the treatment of
tachyarrhythmias. Under the license agreement, Ventritex pays Medtronic
royalties based on a percentage of net sales of Ventritex's products covered by
Medtronic's patents. In July 1993, Ventritex entered into license agreements
with Telectronics and CPI. Under the agreement with CPI, Ventritex and CPI
cross-licensed their respective patent portfolios relating to devices for the
treatment of tachyarrhythmias. Ventritex made a one-time payment to CPI in
settlement of claims relating to past activities and pays CPI royalties based on
a percentage of net sales of Ventritex's products covered by CPI's patents.
Under the agreement with Telectronics, Ventritex and Telectronics cross-licensed
their respective patent portfolios relating to devices for the treatment of
tachyarrhythmias. Ventritex also made a one-time payment to Telectronics in
settlement of ongoing patent infringement litigation between Telectronics and
Ventritex. The Company does not have ongoing royalty obligations to
Telectronics. In connection with the license agreements with CPI and
Telectronics, Ventritex recognized a charge of $18.6 million in fiscal 1993.
This charge included the one-time payments and certain other related settlement
expenses.
 
     The Company's licenses with Medtronic, CPI and Telectronics contain
significant restrictions that may have the effect of preventing or substantially
impeding an acquisition of, change in control of, or certain minority
investments in, the Company. Such restrictions include the possible termination
of various licenses to the Company and the requirement that the Company make a
substantial payment to one of the licensors upon such event.
 
     As a result of the above license agreements, the Company's only pending
legal dispute in the intellectual property area consists of various claims
asserted by and against Intermedics. For more information about the Intermedics
litigation, see "-- Legal Proceedings."
 
     Although the Company believes that it has entered into license agreements
with all of the major participants in the implantable defibrillator market other
than Intermedics, there can be no assurance that other parties will not
institute litigation against the Company. In addition, the license agreements
with Medtronic, Telectronics and CPI do not include patents that are issued
under applications filed after certain specified dates and thus future patent
disputes with Medtronic, Telectronics and CPI are possible. Any future
litigation, as well as any future interference proceedings that may be declared
by the United States Patent and Trademark Office to determine the priority of
inventions, could result in substantial expense to the Company and significant
diversion of effort by the Company's technical and management personnel.
Additional litigation may be necessary to enforce patents issued to or held by
the Company, to
 
                                       31
<PAGE>   33
 
protect trade secrets or know-how owned by the Company or to determine the
enforceability, scope and validity of the proprietary rights of others. An
adverse determination in litigation or interference proceedings to which the
Company is or may become a party could subject the Company to significant
liabilities to third parties or require the Company to seek licenses from third
parties. There can, however, be no assurance that necessary licenses would be
available to the Company on satisfactory terms or at all. Accordingly, an
adverse determination in a judicial or administrative proceeding or failure to
obtain necessary licenses could prevent the Company from manufacturing and
selling its products, which would have a material adverse effect on the
Company's business, financial condition and results of operations and could
adversely affect the Company's ability to continue as a viable entity.
 
GOVERNMENT REGULATION
 
     Clinical testing, manufacture and sale of the Company's products are
regulated by the FDA as medical devices. Under the Federal Food, Drug, and
Cosmetic Act, as amended, all medical devices are classified into three classes,
class I, II or III. Class III devices, such as implantable defibrillators, are
subject to the most stringent FDA review and require submission and approval of
a PMA application or a PMA supplement from the FDA before commencement of
marketing, sales and distribution in the United States.
 
     In order to receive approval of a PMA application, a device must undergo
clinical evaluation under an Investigational Device Exemption ("IDE") that is
granted by the FDA to permit testing of the device in controlled human trials.
In addition to obtaining an IDE from the FDA, the sponsor of the investigational
research must also obtain approval for the research from a hospital
institutional review board or committee established for this purpose. Once an
IDE has been granted, the FDA may allow expansion of the IDE's scope to
additional patient implants or additional clinical sites, or both. The FDA or
the sponsor may suspend clinical trials at any point if either concludes that
clinical subjects are being exposed to an unacceptable health risk or for other
reasons.
 
     Results of clinical trials are presented to the FDA in a PMA application.
In addition to the results of clinical investigation(s), the PMA applicant must
submit other information relevant to the safety and effectiveness of the device
including: the results of non-clinical tests; a full description of the device
and its components; a full description of the methods, facilities and controls
used for manufacturing; and proposed labeling. The FDA staff then reviews the
submitted application and determines whether or not to accept the application
for filing. If accepted for filing, the application is further reviewed by the
FDA and may be subsequently reviewed by an FDA scientific advisory panel
comprised of physicians and others with expertise in the relevant field. The
advisory panel holds a public meeting during which the PMA application is
reviewed and discussed. The scientific advisory panel then issues an approvable
or not approvable recommendation to the FDA or recommends approval with
conditions. Although the FDA is not bound by the opinion of the advisory panel,
the FDA tends to give considerable weight to panel recommendations. The FDA also
typically conducts an inspection to determine whether the Company conforms with
the current Good Manufacturing Practice ("GMP") regulations. If the FDA's
evaluation is favorable, the FDA will subsequently publish an order approving
the PMA for the device. Interested parties can file comments on the order and
seek further FDA review. Although the PMA review process is to be completed
within 180 days from the date the PMA is accepted for filing, this time frame is
frequently exceeded.
 
     The process of obtaining FDA and other required regulatory approvals is
lengthy, expensive and uncertain. Moreover, regulatory approvals, if granted,
may include significant limitations on the indicated uses for which a product
may be marketed. In addition, the FDA may require testing and surveillance
programs to monitor the effect of approved products which have been
commercialized and it has the power to prevent or limit further marketing of a
product based on the results of these post-marketing programs. The FDA actively
enforces regulations prohibiting marketing of products for non-indicated uses.
In addition to FDA inspections conducted prior to the approval of a PMA
application, the FDA also conducts periodic inspections to determine compliance
with GMP and Medical Device Reporting ("MDR") regulations. Failure to comply
with applicable regulatory requirements can result in, among,
 
                                       32
<PAGE>   34
 
other things, fines, suspensions or delays of approvals, seizures or recalls of
products, operating restrictions and criminal prosecutions. Furthermore, changes
in existing regulations or adoption of new regulations could prevent the Company
from obtaining, or affect the timing of, future regulatory approvals. There can
be no assurance that the Company will be able to obtain necessary regulatory
approvals on a timely basis or at all. Delays in receipt of or failure to
receive such approvals or loss of previously received approvals could have a
material adverse effect on the Company's business, financial condition and
results of operations. Furthermore, if a PMA is granted, significant
modifications to the device, manufacturing process or labeling will require a
supplemental PMA or require the submission of a new PMA application, which could
require substantial additional efficacy and safety data and FDA review.
 
     The Company has recently filed a PMA supplement for the Contour
defibrillator and anticipates filing PMA supplements for its single lead
transvenous defibrillation lead systems. The Company is likely to be required to
file additional PMA applications or PMA supplements for new products it
develops. Supplements to a PMA require submission of the same type of
information as a PMA except that the supplement is limited to that information
needed to support the change. There can be no assurance that the FDA will accept
a PMA supplement. The FDA could instead require additional testing of the device
that is the subject of the supplement or could require clinical trials under an
IDE and completion of the entire PMA approval process. Failure to obtain FDA
approval for commercial release through a PMA supplement on a timely basis, or
at all, could have a material adverse effect on the Company's business,
financial condition and results of operations. Further, the MDR regulations
require that the Company provide information to the FDA on deaths or serious
injuries alleged to have been associated with the use of its devices, as well as
product malfunctions that would likely cause or contribute to death or serious
injury if the malfunction were to recur.
 
     The Company is required to register as a medical device manufacturer with
the FDA and state agencies, such as the Food and Drug Branch of the California
Department of Health Services. The Company is subject to inspection on a routine
basis by the State of California and by the FDA for compliance with the FDA's
current GMP and MDR regulations. Those regulations impose certain procedural and
documentation requirements upon the Company with respect to manufacturing and
quality assurance activities and product reporting activities.
 
     Additionally, the Company must comply with various FDA requirements for
design, safety, advertising, labeling and record keeping. Under FDA regulations,
the Company is required to establish a method of device tracking so that the
Company will be able to trace its implantable products from the place of
manufacture to the patient in whom such products are implanted in the United
States. The purpose of this tracking requirement is to facilitate notification
to the patient or recall of the device if such actions become necessary. The
cost of establishing and maintaining a tracking system that complies with the
FDA's regulations may be significant. Failure to establish and maintain the
required tracking system would subject the Company to FDA regulatory sanctions
and the possibility of losing current product approval.
 
     International sales of medical devices are subject to foreign government
regulation, the requirements of which vary substantially from country to
country. The Company has obtained certain foreign governmental approvals and has
applied for additional approvals. The European Community has promulgated rules
that require that medical products receive by mid-1998 the CE mark, an
international symbol of quality and compliance with applicable European medical
device directives. Failure to receive CE mark certification will prohibit the
Company from selling its products in the European Union. International Standards
Organization ("ISO") 9001 certification is one of the CE mark certification
requirements. The Company has established the process and relationships required
to obtain the necessary approvals for the CE mark and has been granted
authorization to affix that mark to all products currently requiring the mark.
 
     The FDA is studying the long-term effects of materials implanted in the
human body and may require manufacturers of implantable devices to conduct
biological testing of such materials. If required, such testing would be
expensive and time consuming and could disrupt the manufacture and sale or
result in
 
                                       33
<PAGE>   35
 
recalls of the Company's products or denials of FDA approval for future
products. Any adverse regulatory actions could have a material adverse effect on
the Company's business, financial condition and results of operations.
 
EMPLOYEES
 
     As of June 30, 1996, the Company had 548 full-time employees, including 164
in product development and process engineering, 240 in manufacturing and quality
assurance, 107 in sales, marketing and clinical engineering, and 37 in
administration. None of the Company's employees is subject to a collective
bargaining agreement. The Company believes that its relationship with its
employees is good. The Company is dependent upon a limited number of key
management and technical personnel. In addition, the Company's future success
will depend in part upon its ability to attract and retain highly qualified
personnel. The Company competes for such personnel with other companies,
academic institutions and government entities. There can be no assurance that
the Company will be successful in hiring or retaining such qualified personnel.
Loss of key personnel or inability to hire or retain qualified personnel could
have a material adverse effect on the Company's business, financial condition
and results of operations.
 
FACILITIES
 
     Ventritex leases an approximately 150,000 square foot facility in
Sunnyvale, California. This facility contains approximately 60,000 square feet
of manufacturing space and approximately 90,000 square feet devoted to research
and administrative offices. The facility is leased through December 2000.
Although the Company believes that this facility is adequate to meet its
requirements at least through fiscal 1997, the Company anticipates the need to
lease additional space. The Company believes that additional space in the
Sunnyvale, California area will be available on commercially reasonable terms.
The Company also leases space in South Carolina for manufacturing activities and
in Europe for sales, clinical engineering and other activities.
 
LEGAL PROCEEDINGS
 
     The Company is currently in litigation with one of its competitors,
Intermedics. In response to threats from Intermedics, the Company filed a
declaratory judgment action in the United States District Court in the Northern
District of California in January 1993, asking the court to declare that certain
patents which Intermedics had asserted were being infringed by the Company were,
in fact, invalid, unenforceable or not infringed. Intermedics then filed several
actions in the United States District Court in the Southern District of Texas
alleging infringement by the Company of nine Intermedics patents. Initially,
this litigation was focused on procedural issues relating to whether the dispute
would be tried in California or Texas. On October 12, 1994, the United States
District Court for the Northern District of California denied Intermedics motion
to transfer Ventritex's pending suits to Texas and granted Ventritex's motion to
enjoin Intermedics from further prosecution of its aforementioned suits in
Texas. The United States District Court for the Southern District of Texas
thereafter issued an order transferring to California all of the Texas cases
which Intermedics had served upon Ventritex. The Court has indicated that the
trial in connection with the above described actions will begin May 5, 1997.
 
     The Company filed a further action in the Northern District of California
in July 1993 seeking a declaratory judgment that the patents that Intermedics
has asserted against the Company are not infringed by Ventritex, are invalid and
are unenforceable. This action, which was filed against Intermedics, its parent
and affiliate companies, SulzerMedica and Sulzer, Inc., seeks damages based upon
claims for antitrust law violations, malicious prosecution, conspiracy and
breach of contract. Intermedics, SulzerMedica and Sulzer, Inc. have moved to
stay or dismiss the Company's damage claims, and the Court ordered that certain
of these claims be dismissed without prejudice and that others be stayed pending
determination of other issues in the parties' various lawsuits.

     In the above actions, Intermedics seeks judgments against Ventritex for
damages, attorneys fees and injunctive relief. It is expected that Intermedics
will, during the course of the litigation, seek to obtain various types of
pretrial relief which include, but are not limited to, summary judgments,
dismissals of Ventritex's claims and preliminary injunctions. In January 1995,
Intermedics filed a motion for partial summary judgment and for issuance of a
preliminary injunction based on alleged infringement of one of its patents.
Ventritex vigorously contested these motions and requested the United States
Patent and Trademark Office to conduct a reexamination of claim 28 of
Intermedics U.S. Patent No. 4,880,005 upon which these motions are based. The
Court denied Intermedics' partial summary judgment motion, and, as a result,
Intermedics' preliminary injunction request was withdrawn. The Patent Office, on
May 28, 1996, issued a second final rejection of claim 28 of the 4,880,005
patent. Intermedics subsequently requested reconsideration of the final
rejection. The United States Patent and Trademark Office has indicated that,
upon reconsideration, the rejection appears to have been overcome. The Company
believes that Intermedics will make renewed efforts to obtain partial summary
judgment and a preliminary injunction. On June 6, 1996, Intermedics filed with
the United States Patent and Trademark Office a request for reexamination of
U.S. Patent No. 4,830,006 and on June 7, 1996, Intermedics filed a request for
reexamination of U.S. Patent No. 4,913,145. Both patents are being asserted by
Intermedics against the Company. The requests are based on references identified
by Ventritex as being pertinent to the patents in response to discovery requests
by Intermedics.
 
     Since the Company brought a declaratory relief action against Intermedics
in January 1993, Intermedics has filed suits against the Company's two principal
competitors, Medtronic and CPI, alleging infringement of several of the same
patents which it has asserted against the Company. None of these actions has yet
been set for trial.
 
     In addition to its patent infringement claims, Intermedics had previously
alleged trade secret misappropriation and related acts by the Company and two of
its officers, who were formerly employees of Intermedics. In this lawsuit, the
Company filed counterclaims against Intermedics for infringement of two of
Ventritex's patents. These counterclaims are still pending. Certain of the trade
secret misappropriation and related claims were tried in 1992 before a United
States District Court jury in San Francisco. The jury returned a unanimous
verdict in favor of the Company and its officers and found that Intermedics had
acted in bad faith in continuing to pursue the trade secret misappropriation
claims. The Court set aside the bad faith portion of the verdict based on
Intermedics claim of an erroneous jury instruction. A new trial on the bad faith
issue has been ordered, but no trial date has been set. The judgment dismissed
all of Intermedics trade secret claims against the Company and its officers and
was affirmed on appeal.
 
     In addition to the above-mentioned litigation, the Company is also involved
in other litigation in the normal course of business. Although an adverse
determination in the Intermedics proceedings or in other litigation or
administrative proceedings could have a material adverse effect on the Company,
based upon the nature of the claims made and the investigation completed to
date, the Company believes the outcome of the described actions will not have a
material adverse effect on the financial position or results of operations of
the Company.

                              DESCRIPTION OF NOTES
 
     The Notes are to be issued under an Indenture, to be dated as of
            , 1996 (the "Indenture"), between the Company and State Street Bank
and Trust Company, as Trustee (the "Trustee"), a copy of which is filed as an
exhibit to the Registration Statement. Wherever particular defined terms of the
Indenture (including the Notes) are referred to, such defined terms are
incorporated herein by reference (the Notes and various terms relating to the
Notes being referred to in the Indenture as "Securities"). References in this
section to the "Company" are solely to Ventritex, Inc. and not to its
 
                                       37
<PAGE>   39
 
subsidiaries. The following summaries of certain provisions of the Indenture do
not purport to be complete and are subject to, and are qualified in their
entirety by reference to, the detailed provisions of the Notes and the
Indenture, including the definitions therein of certain terms. Section
references below are references to Sections of the Indenture.
 
GENERAL
 
     The Notes will be unsecured subordinated obligations of the Company, will
be limited to $100,000,000 aggregate principal amount, and will mature on
            , 2001. The Notes will bear interest at the rate per annum shown on
the front cover of this Prospectus from             , 1996, payable semiannually
on             and             of each year, commencing on             , 1997.
Interest payable per $1,000 principal amount of Notes for the period from
            , 1996 to             , 1997 will be $          . (sec.sec. 301 and
307)
 
     The Notes will be convertible into Common Stock initially at the conversion
rate stated on the cover page hereof, subject to adjustment upon the occurrence
of certain events described under "-- Conversion Rights," at any time on or
after           , 1996 and prior to the close of business on the maturity date,
unless previously redeemed or repurchased. (sec. 1301)
 
     The Notes are redeemable under the circumstances and at the redemption
prices set forth below under "-- Optional Redemption," plus accrued interest to
the redemption date. (sec. 203)
 
     The Notes will be issued only in fully registered form, without coupons, in
denominations of $1,000 and any integral multiple thereof. (sec. 302) No service
charge will be made for any registration of transfer or exchange of Notes, but
the Company may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. (sec. 305)
 
CONVERSION RIGHTS
 
     The Holder of any Note will have the right, at the Holder's option, to
convert any portion of the principal amount of a Note that is an integral
multiple of $1,000 into shares of Common Stock at any time on or after
          , 1996 and prior to the close of business on the maturity date, unless
previously redeemed or repurchased, at a conversion rate of           shares of
Common Stock per U.S. $1,000 principal amount of Notes (the "Conversion Rate")
(equivalent to a conversion price of approximately $          per share of
Common Stock) (subject to adjustment as described below). The right to convert a
Note called for redemption will terminate at the close of business on the
Business Day prior to the Redemption Date for such Note, while the right to
convert a Note tendered for repurchase will terminate at the close of business
on the Repurchase Date for such Note. The Company agrees, however, that it will
not call the Notes for redemption on a Redemption Date which also is a Record
Date or an Interest Payment Date for the payment of interest on the Notes. (sec.
1301)
 
     The right of conversion attaching to any Note may be exercised by the
Holder by delivering the Note at the specified office of the Conversion Agent,
accompanied by a duly signed and completed notice of conversion, a copy of which
may be obtained from the Trustee. The conversion date will be the date on which
the Note and the duly signed and completed notice of conversion are so
delivered. As promptly as practicable on or after the conversion date, the
Company will issue and deliver to the Trustee a certificate or certificates for
the number of full shares of Common Stock issuable upon conversion, together
with payment in lieu of any fraction of a share; such certificate will be sent
by the Trustee to the Conversion Agent (if other than the Trustee) for delivery
to the Holder. Such shares of Common Stock issuable upon conversion of the
Notes, in accordance with the provisions of the Indenture, will be fully paid
and nonassessable and will rank pari passu with the other shares of Common Stock
of the Company outstanding from time to time. Any Note surrendered for
conversion during the period from the close of business on any Regular Record
Date next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date (except Notes (or portions thereof) called for redemption
on a Redemption Date or which are repurchasable on a Repurchase Date occurring,
in either case, within such period) must be accompanied by payment of an amount
equal to the interest payable on such Interest
 
                                       38
<PAGE>   40
 
Payment Date on the principal amount of Notes being surrendered for conversion.
The interest so payable on such Interest Payment Date with respect to any Note
(or portion thereof, if applicable) which has been called for redemption on a
Redemption Date, or which may be repurchased on a Repurchase Date, occurring, in
either case, during the period from the close of business on any Record Date
next preceding any Interest Payment Date to the opening of business on such
Interest Payment Date, which Note (or portion thereof, if applicable) is
surrendered for conversion during such period, shall be paid to the Holder of
such Note being converted in an amount equal to the interest that would have
been payable on such Note if such Note had been converted as of the close of
business on such Interest Payment Date. The interest so payable on such Interest
Payment Date in respect of any Note (or portion thereof, as the case may be)
which has not been called for redemption on a Redemption Date, or is not
eligible for repurchase on a Repurchase Date, occurring, in either case, during
the period from the close of business on any Record Date next preceding any
Interest Payment Date to the opening of business on such Interest Payment Date,
which Note (or portion thereof, as the case may be) is surrendered for
conversion during such period, shall be paid to the Holder of such Note as of
such Regular Record Date. Interest payable in respect of any Note surrendered
for conversion or repurchase on or after an Interest Payment Date shall be paid
to the Holder of such Note as of the next preceding Regular Record Date,
notwithstanding the exercise of the right of conversion. As a result of the
foregoing provisions, except as provided above, Holders that surrender Notes for
conversion on a date that is not an Interest Payment Date will not receive any
interest for the period from the Interest Payment Date next preceding the date
of conversion to the date of conversion or for any later period, even if the
Notes are surrendered after a notice of redemption (except for the payment of
interest on Notes called for redemption on a Redemption Date or to be
repurchased on a Repurchase Date between a Regular Record Date and the Interest
Payment Date to which it relates, as provided above). No other payment or
adjustment for interest, or for any dividends in respect of Common Stock, will
be made upon conversion. Holders of Common Stock issued upon conversion will not
be entitled to receive any dividends payable to holders of Common Stock as of
any record time or date before the close of business on the conversion date. No
fractional shares will be issued upon conversion but, in lieu thereof, the
Company will pay an appropriate amount in cash based on the market price of
Common Stock at the close of business on the day of conversion. (sec.sec. 101,
203, 307, 1302 and 1303)
 
     A Holder delivering a Note for conversion will not be required to pay any
taxes or duties in respect of the issue or delivery of Common Stock on
conversion but will be required to pay any tax or duty which may be payable in
respect of any transfer involved in the issue or delivery of the Common Stock in
a name other than that of the Holder of the Note. Certificates representing
shares of Common Stock will not be issued or delivered unless all taxes and
duties, if any, payable by the Holder have been paid. (sec.sec. 1302 and 1308)
 
     The Conversion Rate is subject to adjustment in certain events, including,
without duplication: (a) dividends (and other distributions) payable in Common
Stock, (b) the issuance to all holders of Common Stock of rights, options or
warrants entitling them to subscribe for or purchase Common Stock at less than
the then Current Market Price of such Common Stock (determined as provided in
the Indenture) as of the record date for shareholders entitled to receive such
rights, options or warrants, (c) subdivisions, combinations and
reclassifications of Common Stock, (d) distributions to all holders of Common
Stock of evidences of indebtedness of the Company, shares of capital stock, cash
or assets (including securities, but excluding those dividends, rights, options,
warrants and distributions referred to above, dividends and distributions paid
exclusively in cash and in mergers and consolidations to which the next
succeeding paragraph applies), (e) distributions consisting exclusively of cash
(excluding any cash portion of distributions referred to in (d) above) to all
holders of Common Stock in an aggregate amount that, combined together with (i)
other such all-cash distributions made within the preceding 12 months in respect
of which no adjustment has been made and (ii) any cash and the fair market value
of other consideration payable in respect of any tender offer by the Company or
any of its subsidiaries for Common Stock concluded within the preceding 12
months in respect of which no adjustment has been made, exceeds 10% of the
Company's market capitalization (being the product of the then Current Market
Price per share of the Common Stock and the number of shares of Common Stock
then
 
                                       39
<PAGE>   41
 
outstanding) on the record date for such distribution, and (f) the successful
completion of a tender offer made by the Company or any of its subsidiaries for
Common Stock which involves an aggregate consideration that, together with (i)
any cash and other consideration payable in a tender offer by the Company or any
of its subsidiaries for Common Stock expiring within the 12 months preceding the
expiration of such tender offer in respect of which no adjustment has been made
and (ii) the aggregate amount of any such all-cash distributions referred to in
(e) above to all holders of Common Stock within the 12 months preceding the
expiration of such tender offer in respect of which no adjustments have been
made, exceeds 10% of the Company's market capitalization on the expiration of
such tender offer. With respect to Rights (as defined below) issued pursuant to
the Rights Agreement (as defined below), if Holders of the Notes exercising the
right of conversion attaching thereto after the Distribution Date (as defined in
the Rights Agreement) are not entitled to receive the Rights that would
otherwise be attributable (but for the date of conversion) to the shares of
Common Stock received upon such conversion, the Conversion Rate will be adjusted
as though the Rights were being distributed to holders of the Common Stock on
the Distribution Date. If such an adjustment is made and the Rights are later
redeemed, invalidated or terminated, then a corresponding reversing adjustment
will be made to the Conversion Rate on an equitable basis. The Company reserves
the right to make such increases in the Conversion Rate in addition to those
required in the foregoing provisions as it considers to be advisable in order
that any event treated for federal income tax purposes as a dividend or
distribution of stock or issuance of rights or warrants to purchase or subscribe
for stock will not be taxable to the recipients. No adjustment of the Conversion
Rate will be required to be made until the cumulative adjustments amount to 1.0%
or more of the Conversion Rate. (sec. 1304) The Company shall compute any
adjustments to the Conversion Rate pursuant to this paragraph and will give
notice to the Holders of the Notes of any adjustments. (sec. 1305)
 
     In case of any consolidation or merger of the Company with or into another
Person or any merger of another Person into the Company (other than a merger
which does not result in any reclassification, conversion, exchange or
cancellation of the Common Stock), or in case of any sale or transfer of all or
substantially all of the assets of the Company, each Note then outstanding will,
without the consent of the Holder of any Note, become convertible only into the
kind and amount of securities, cash and other property receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of
Common Stock into which such Note was convertible immediately prior thereto
(assuming such holder of Common Stock failed to exercise any rights of election
and that such Note was then convertible). (sec. 1311)
 
     The Company from time to time may increase the Conversion Rate by any
amount for any period of at least 20 days, in which case the Company shall give
at least 15 days' notice of such increase, if the Board of Directors has made a
determination that such increase would be in the best interests of the Company,
which determination shall be conclusive. No such increase shall be taken into
account for purposes of determining whether the closing price of the Common
Stock exceeds the Conversion Price by 105% in connection with an event which
otherwise would be a Change of Control.
 
     If at any time the Company makes a distribution of property to its
stockholders which would be taxable to such stockholders as a dividend for
United States federal income tax purposes (e.g., distributions of evidences of
indebtedness or assets of the Company, but generally not stock dividends on
Common Stock or rights to subscribe for Common Stock) and, pursuant to the
anti-dilution provisions of the Indenture, the number of shares into which Notes
are convertible is increased, such increase may be deemed for federal income tax
purposes to be the payment of a taxable dividend to Holders of Notes. See
"Certain Federal Income Tax Considerations."
 
SUBORDINATION
 
     The payment of the principal of, premium, if any, and interest on
(including any amounts payable upon the redemption or repurchase of the Notes
permitted by the Indenture), the Notes will be subordinated in right of payment,
to the extent set forth in the Indenture, to the prior payment in full of the
principal of, premium, if any, interest and other amounts in respect of all
Senior Indebtedness of the
 
                                       40
<PAGE>   42
 
Company. As of June 30, 1996, the Company had no outstanding indebtedness that
would have constituted Senior Indebtedness. Senior Indebtedness is defined in
the Indenture to mean the principal of (and premium, if any) and interest
(including all interest accruing subsequent to the commencement of any
bankruptcy or similar proceeding, whether or not a claim for post-petition
interest is allowable as a claim in any such proceeding) on, and all fees and
other amounts payable in connection with, the following, whether absolute or
contingent, secured or unsecured, due or to become due, outstanding on the date
of the Indenture or thereafter created, incurred or assumed: (a) indebtedness of
the Company to banks, insurance companies and other financial institutions
evidenced by credit or loan agreements, notes or other written obligations, (b)
all other indebtedness of the Company (including indebtedness of others
guaranteed by the Company) other than the Notes, whether outstanding on the date
of the Indenture or thereafter created, incurred or assumed, which is (i) for
money borrowed or (ii) evidenced by a note, security, debenture, bond or similar
instrument, (c) obligations of the Company as lessee under leases required to be
capitalized on the balance sheet of the lessee under generally accepted
accounting principles or in respect of any lease or related document (including
a purchase agreement) which provides that the Company is contractually obligated
to purchase or cause a third party to purchase the leased property and thereby
effectively guarantees a minimum residual value of the leased property to the
landlord and the obligations of the Company under such lease or related document
to purchase or cause a third party to purchase such leased property, (d)
obligations of the Company under interest rate and currency swaps, caps, floors,
collars or similar agreements or arrangements, (e) renewals, extensions,
modifications, restatements and refundings of, and any amendments, modifications
or supplements to, or any indebtedness or obligation issued in exchange for, any
such indebtedness or obligation described in clauses (a) through (d) of this
paragraph; provided, however, that Senior Indebtedness shall not include any
such indebtedness or obligation if the terms of such indebtedness or obligation
(or the terms of the instrument under which, or pursuant to which, it is issued)
expressly provides that such indebtedness or obligation shall not be senior in
right of payment to the Notes, or expressly provides that such indebtedness or
obligation is "pari passu" with or "junior" to the Notes. "Designated Senior
Indebtedness" means any particular Senior Indebtedness in which the instrument
creating or evidencing the same or the assumption or guarantee thereof (or
related agreements or documents to which the Company is a party) expressly
provides that such Senior Indebtedness shall be "Designated Senior Indebtedness"
for purposes of the Indenture (provided that such instrument, agreement or other
document may place limitations and conditions on the right of such Senior
Indebtedness to exercise the rights of Designated Senior Indebtedness).
(sec.sec. 101, 1201 and 1202)
 
     In the event of the acceleration of the maturity of any Notes, the holders
of all Senior Indebtedness will first be entitled to receive payment in full in
cash of all amounts due or to become due thereon before the Holders of the Notes
will be entitled to receive any payment for the principal of or premium, if any,
interest on, or other obligations in respect of, the Notes. The Indenture will
further require that the Company promptly notify holders of Senior Indebtedness
if payment of the Notes is accelerated because of an Event of Default. The
Company also may not make any payment upon or in respect of the Notes if (i) a
default in the payment of the principal of, premium, if any, interest, rent or
other obligations in respect of Senior Indebtedness occurs and is continuing
beyond any applicable period of grace or (ii) any other default occurs and is
continuing with respect to Designated Senior Indebtedness that permits holders
of the Designated Senior Indebtedness as to which such default relates to
accelerate the maturity thereof and the Trustee receives a notice of such
default (a "Payment Blockage Notice") from the Company or other person permitted
to give such notice under the Indenture. Payments on the Notes may and shall be
resumed (a) in the case of a payment default, upon the date on which such
default is cured or waived and (b) in case of a nonpayment default, the earlier
of the date on which such nonpayment default is cured or waived or 179 days
after the date on which the applicable Payment Blockage Notice is received. No
new period of payment blockage may be commenced unless and until (i) 365 days
have elapsed since the effectiveness of the immediately prior Payment Blockage
Notice and (ii) all scheduled payments of principal, premium, if any, and
interest on the Notes that have come due have been paid in full in cash. No
nonpayment default that existed or was continuing on the date of
 
                                       41
<PAGE>   43
 
delivery of any Payment Blockage Notice to the Trustee shall be, or be made, the
basis for a subsequent Payment Blockage Notice.
 
     Upon any acceleration of the principal due on the Notes or payment or
distribution of assets of the Company to creditors upon any dissolution, winding
up, liquidation or reorganization, whether voluntary or involuntary, or in
bankruptcy, insolvency, receivership or other similar proceedings of the
Company, all principal, premium, if any, and interest or other amounts due on
all Senior Indebtedness must be paid in full before the Holders of the Notes are
entitled to receive any payment. By reason of such subordination, in the event
of insolvency, creditors of the Company who are holders of Senior Indebtedness
are likely to recover more, ratably, than the Holders of the Notes, and such
subordination may result in a reduction or elimination of payments to the
Holders of the Notes. (sec. 1202)
 
     The Notes are obligations exclusively of the Company. To the extent the
Company were to commence conducting certain operations or increase the level of
existing operations through subsidiaries, the cash flow and the consequent
ability to service debt, including the Notes, of the Company would be partially
dependent upon the earnings of any such subsidiaries and the distribution of
those earnings to the Company. Any such subsidiaries would be separate and
distinct legal entities, and would have no obligations, contingent or otherwise,
to pay any amounts due under the Notes or to make any funds available therefor,
whether by dividends, distributions, loans or otherwise. In addition, the
payment of dividends or distributions and the making of loans and advances to
the Company by any such subsidiaries could be subject to statutory or
contractual restrictions, and could be contingent upon the earnings of those
subsidiaries and subject to various business considerations. Any right of the
Company to receive assets of subsidiaries upon their liquidation or
reorganization (and the consequent right of the holders of the Notes to
participate in these assets) would be effectively subordinated to the claims of
that subsidiary's creditors (including trade creditors), except to the extent
that the Company is itself recognized as a creditor of such subsidiary, in which
case the claims of the Company would still be subordinate to any security
interests in the assets of such subsidiary and any indebtedness of such
subsidiary senior to that held by the Company. As of June 30, 1996, the
Company's subsidiaries had no indebtedness outstanding for money borrowed.
 
     The Indenture does not limit the Company's ability to incur Senior
Indebtedness or any other indebtedness.
 
OPTIONAL REDEMPTION
 
     The Notes may not be redeemed prior to             , 1999. Thereafter, the
Notes may be redeemed, in whole or in part, at the option of the Company, upon
not less than 20 nor more than 60 days' prior notice as provided under " --
Notices" below, at the redemption prices set forth below.
 
     The redemption prices (expressed as a percentage of principal amount) are
as follows for the 12-month period beginning on             of the following
years:
 
<TABLE>
<CAPTION>
                                                                       REDEMPTION
                                      YEAR                               PRICE

            2000

and thereafter at a redemption price equal to 100% of the principal amount, in
each case together with accrued interest to the date of redemption. (sec. 203,
Article Eleven)
 
     No sinking fund is provided for the Notes.
 
REPURCHASE AT OPTION OF HOLDERS UPON A CHANGE OF CONTROL
 
     If a Change of Control (as defined) occurs, each Holder of Notes shall have
the right, at the Holder's option, to require the Company to repurchase all of
such Holder's Notes, or any portion of the principal
 
                                       42
<PAGE>   44
 
amount thereof that is equal to $1,000 or an integral multiple of $1,000 in
excess thereof, on the date (the "Repurchase Date") that is 45 days after the
date of the Company Notice (as defined), at a price equal to 100% of the
principal amount of the Notes to be repurchased, together with interest accrued
to the Repurchase Date (the "Repurchase Price"). (sec. 1401)
 
     The Company may, at its option, in lieu of paying the Repurchase Price in
cash, pay the Repurchase Price in Common Stock valued at 95% of the average of
the closing prices of the Common Stock for the five consecutive Trading Days
ending on and including the third Trading Day preceding the Repurchase Date;
provided that payment may not be made in Common Stock unless the Company
satisfies certain conditions with respect to such payment as provided in the
Indenture. (sec.sec. 1401 and 1402)
 
     Within 30 days after the occurrence of a Change of Control, the Company is
obligated to give to all Holders of the Notes notice, as provided in the
Indenture (the "Company Notice"), of the occurrence of such Change of Control
and of the repurchase right arising as a result thereof, or, at the request of
the Company on or before the 15th day after such occurrence, the Trustee shall
give the Company Notice. The Company must also deliver a copy of the Company
Notice to the Trustee and to the office of each Paying Agent. To exercise the
repurchase right, a Holder of Notes must deliver on or before the 30th day after
the date of the Company Notice irrevocable written notice to the Trustee or
Paying Agent of the Holder's exercise of such right, together with the Notes
with respect to which the right is being exercised. (sec. 1403)
 
     A Change of Control shall be deemed to have occurred at such time after the
original issuance of the Notes as there shall occur:
 
          (i) the acquisition by any Person (including any syndicate or group
     deemed to be a "person" under Section 13(d)(3) of the Exchange Act) of
     beneficial ownership, directly or indirectly, through a purchase, merger or
     other acquisition transaction or series of transactions, of shares of
     capital stock of the Company entitling such Person to exercise 50% or more
     of the total voting power of all shares of capital stock of the Company
     entitled to vote generally in elections of directors, other than any such
     acquisition by the Company, any subsidiary of the Company or any employee
     benefit plan of the Company; or
 
          (ii) any consolidation or merger of the Company with or into any other
     Person, any merger of another Person into the Company, or any conveyance,
     sale, transfer or lease of all or substantially all of the assets of the
     Company to another Person (other than (a) any such transaction (x) which
     does not result in any reclassification, conversion, exchange or
     cancellation of outstanding shares of Common Stock and (y) pursuant to
     which holders of Common Stock immediately prior to such transaction have
     the entitlement to exercise, directly or indirectly, 50% or more of the
     total voting power of all shares of capital stock entitled to vote
     generally in the election of directors of the continuing or surviving
     person immediately after such transaction and (b) any merger which is
     effected solely to change the jurisdiction of incorporation of the Company
     and results in a reclassification, conversion or exchange of outstanding
     shares of Common Stock into solely shares of common stock);
 
provided, however, that a Change of Control shall not be deemed to have occurred
if either (a) the closing price per share of the Common Stock for any five
Trading Days within the period of 10 consecutive Trading Days ending immediately
after the later of the Change of Control or the public announcement of the
Change of Control (in the case of a Change of Control under clause (i) above) or
ending immediately before the Change of Control (in the case of a Change of
Control under clause (ii) above) shall equal or exceed 105% of the Conversion
Price of the Notes in effect on each such Trading Day or (b) all of the
consideration (excluding cash payments for fractional shares) in a transaction
or transactions constituting the Change of Control described in clause (ii)
above consists of shares of common stock traded on a national securities
exchange or quoted on the Nasdaq National Market and as a result of such
transaction or transactions the Notes become convertible solely into such common
stock. The "Conversion Price" is equal to $1,000 dividend by the Conversion
Rate. "Beneficial owner" shall be
 
                                       43
<PAGE>   45
 
determined in accordance with Rule 13d-3 promulgated by the Commission under the
Exchange Act, as in effect on the date of original execution of the Indenture.
(sec. 1404)
 
     The Company's ability to repurchase Notes upon the occurrence of a Change
of Control is subject to limitations. There can be no assurance that the Company
would have the financial resources, or would be able to arrange financing, to
pay the Repurchase Price for all the Notes that might be delivered by Holders of
Notes seeking to exercise the purchase right. In addition, the Company's ability
to purchase Notes may be limited or prohibited by the terms of its Senior
Indebtedness. In addition, the Company's ability to purchase Notes with cash may
also be limited by the terms of its subsidiaries' then-existing borrowing
arrangements due to dividend restrictions. Any failure by the Company to
repurchase the Notes when required following a Change of Control could result in
an Event of Default under the Indenture whether or not such repurchase is
permitted by the subordination provisions of the Indenture. Any such default
may, in turn, cause a default under Senior Indebtedness of the Company.
Moreover, the occurrence of a Change of Control may cause an event of default
under Senior Indebtedness of the Company. As a result, in any such case, any
repurchase of the Notes would, absent a waiver, be prohibited under the
subordination provisions of the Indenture until the Senior Indebtedness is paid
in full. See "-- Subordination" and "Risk Factors -- Subordination."
 
     Rule 13e-4 under the Exchange Act requires the dissemination of certain
information to security holders in the event of an issuer tender offer and may
apply in the event that the repurchase option becomes available to Holders of
the Notes. The Company will comply with this rule to the extent applicable at
that time.
 
     The foregoing provisions would not necessarily afford Holders of the Notes
protection in the event of highly leveraged or other transactions involving the
Company that may adversely affect Holders.
 
MERGERS AND SALES OF ASSETS BY THE COMPANY
 
     The Company may not consolidate with or merge into any other Person or,
directly, or indirectly, convey, transfer, sell, lease or otherwise dispose of
its properties and assets substantially as an entirety to any Person (other than
a wholly-owned subsidiary), and the Company may not permit any Person (other
than a wholly-owned subsidiary) to consolidate with or merge into the Company or
convey, transfer, sell, lease or otherwise dispose of its properties and assets
substantially as an entirety to the Company, unless (a) the Person formed by
such consolidation or into which the Company is merged or the Person to which
the properties and assets of the Company are so transferred or leased is a
corporation, limited liability company, partnership or trust organized and
existing under the laws of the United States, any State thereof or the District
of Columbia and has expressly assumed the due and punctual payment of the
principal of, premium, if any, and interest on the Notes and the performance of
the other covenants of the Company under the Indenture, (b) immediately after
giving effect to such transaction, no Event of Default, and no event which,
after notice or lapse of time or both, would become an Event of Default, shall
have occurred and be continuing, and (c) the Company has provided to the Trustee
an Officer's Certificate and Opinion of Counsel as provided in the Indenture.
(sec. 801)
 
EVENTS OF DEFAULT
 
     The following will be Events of Default under the Indenture: (a) failure to
pay principal or Redemption Price of any Note when due, whether or not such
payment is prohibited by the subordination provisions of the Indenture; (b)
failure to pay any interest on any Note when due, continuing for 30 days,
whether or not such payment is prohibited by the subordination provisions of the
Indenture; (c) default in the Company's obligation to provide a Company Notice
of a Change in Control; (d) failure to perform any other covenant of the Company
in the Indenture, continuing for 60 days after written notice as provided in the
Indenture; (e) any indebtedness for money borrowed by the Company in an
aggregate principal amount in excess of $10,000,000 is not paid at final
maturity or upon acceleration thereof and such default in payment or
acceleration is not cured or rescinded within 30 days after written notice as
provided in the Indenture; and (f) certain events of bankruptcy, insolvency or
reorganization. (sec. 501)
 
                                       44
<PAGE>   46
 
Subject to the provisions of the Indenture relating to the duties of the Trustee
in case an Event of Default shall occur and be continuing, the Trustee will be
under no obligation to exercise any of its rights or powers under the Indenture
at the request or direction of any of the Holders, unless such Holders shall
have offered to the Trustee reasonable indemnity. (sec. 603) Subject to such
provisions for the indemnification of the Trustee, the Holders of a majority in
aggregate principal amount of the Outstanding Notes will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or exercising any trust or power conferred on the
Trustee. (sec. 512)
 
     If an Event of Default (other than an Event of Default specified in
subsection (f) above) occurs and is continuing, either the Trustee or the
Holders of not less than 25% in aggregate principal amount of the Outstanding
Notes, by notice in writing to the Company, declare the principal of all the
Notes to be due and payable immediately, and upon any such declaration such
principal and any accrued interest thereon will become immediately due and
payable. If an Event of Default specified in subsection (f) occurs and is
continuing, the principal and any accrued interest on all of the then
Outstanding Notes shall ipso facto become due and payable immediately without
any declaration or other Act on the part of the Trustee or any Holder. (sec.
502)
 
     At any time after a declaration of acceleration has been made but before a
judgment or decree based on acceleration, the Holders of a majority in aggregate
principal amount of Outstanding Notes may, under certain circumstances, rescind
and annul such acceleration if all Events of Default, other than the nonpayment
of accelerated principal and interest have been cured or waived as provided in
the Indenture. (sec. 502)
 
     No Holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such Holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and unless also the Holders of at least 25% in aggregate principal
amount of the Outstanding Notes shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as trustee,
and the Trustee shall not have received from the Holders of a majority in
aggregate principal amount of the Outstanding Notes a direction inconsistent
with such request and shall have failed to institute such proceeding within 60
days. (sec. 507) However, such limitations do not apply to a suit instituted by
a Holder of a Note for the enforcement of payment of the principal of, premium,
if any, or interest on such Note on or after the respective due dates expressed
in such Note or of the right to convert such Note in accordance with the
Indenture. (sec. 508)
 
     The Company will be required to furnish to the Trustee annually a statement
as to the performance by the Company of certain of its obligations under the
Indenture and as to any default in such performance. (sec. 1004)
 
MODIFICATION AND WAIVER
 
     Modifications and amendments of the Indenture may be made, and certain past
defaults by the Company may be waived, either with the written consent of the
Holders of not less than a majority in aggregate principal amount of the Notes
at the time Outstanding. However, no such modification or amendment may, without
the consent of the Holder of each outstanding Note affected thereby, (a) change
the Stated Maturity of the principal of, or any installment of interest on, any
Note, (b) reduce the principal amount of, or the premium, if any, or rate of
interest on, any Note, (c) reduce the amount payable upon redemption or
mandatory repurchase, (d) modify the provisions with respect to the repurchase
right of the Holders in a manner adverse to the Holders, (e) change the place or
currency of payment of principal of, premium, if any, or interest on, any Note,
(f) impair the right to institute suit for the enforcement of any payment on or
with respect to any Note (including any payment of the Repurchase Right in
respect of such Note), (g) modify the obligation of the Company to maintain an
office or agency in New York City, (h) except as otherwise permitted by the
Indenture or contemplated by provisions concerning consolidation, merger,
conveyance, transfer, sale or lease of all or substantially all of the property
and assets of the Company, adversely affect the right of Holders to convert any
of the Notes or to require the Company to repurchase any Note other than as
provided in the Indenture, (i)
 
                                       45
<PAGE>   47
 
modify the subordination provisions in a manner adverse to the Holders of the
Notes, (j) reduce the above-stated percentage of Outstanding Notes necessary to
modify or amend the Indenture, or (k) reduce the percentage of aggregate
principal amount of Outstanding Notes necessary for waiver of compliance with
certain provisions of the Indenture or for waiver of certain defaults. (sec.sec.
902 and 513)
 
     The Holders of a majority in aggregate principal amount of the Outstanding
Notes may waive compliance by the Company with certain restrictive provisions of
the Indenture. (sec. 1009) The Holders of a majority in aggregate principal
amount of the Outstanding Notes also may waive any past default under the
Indenture, except a default in the payment of principal, premium, if any, or
interest. (sec. 513)
 
TRANSFER AND EXCHANGE
 
     The Company has initially appointed the Trustee as security registrar and
transfer agent, acting through its New York agency in the City of New York. The
Company reserves the right to vary or terminate the appointment of the security
registrar or of any transfer agent or to appoint additional or other transfer
agents or to approve any change in the office through which any security
registrar or any transfer agent acts. (sec.sec. 305 and 1002)
 
PURCHASE AND CANCELLATION
 
     The Company or any subsidiary may at any time and from time to time
purchase Notes at any price in the open market or otherwise.
 
     All Notes surrendered for payment, redemption, repurchase, registration of
transfer or exchange or conversion shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee. All Notes so delivered to the
Trustee shall be cancelled promptly by the Trustee. No Notes shall be
authenticated in lieu of or in exchange for any Notes cancelled as provided in
the Indenture. Unless otherwise requested by the Company and confirmed in
writing, the Trustee shall, from time to time but not less than once annually,
destroy all cancelled Notes and deliver to the Company a certificate of
destruction, which certificate shall specify the number, principal amount and,
in the case of Notes the form of each cancelled Note so destroyed. (sec. 309)
 
TITLE
 
     The Company and the Trustee may treat the registered owner (as reflected in
the Security Register) of any Note as the absolute owner thereof (whether or not
such Note shall be overdue) for the purpose of making payment and for all other
purposes.
 
NOTICES
 
     Notice to Holders of the Notes will be given by mail to the addresses of
such Holders as they appear in the Security Register. Such notices will be
deemed to have been given on the date of the first such publication or on the
date of such mailing, as the case may be. (sec.sec. 101 and 106)
 
     Notice of a redemption of Notes will be given at least once not less than
20 nor more than 60 days prior to the redemption date (which notice shall be
irrevocable) and will specify the redemption date.
 
REPLACEMENT OF NOTES
 
     Notes that become mutilated, destroyed, stolen or lost will be replaced by
the Company at the expense of the Holder upon delivery to the Trustee of the
mutilated Notes or evidence of the loss, theft or destruction thereof
satisfactory to the Company and the Trustee. In the case of a lost, stolen or
destroyed Note indemnity satisfactory to the Trustee and the Company may be
required at the expense of the Holder of such Note before a replacement Note
will be issued. (sec. 306)
 
                                       46
<PAGE>   48
 
PAYMENT OF STAMP AND OTHER TAXES
 
     The Company shall pay all stamp and other duties, if any, which may be
imposed by the United States or any political subdivision thereof or taxing
authority thereof or therein with respect to the issuance of the Notes. The
Company will not be required to make any payment with respect to any other tax,
assessment or governmental charge imposed by any government or any political
subdivision thereof or taxing authority therein.
 
SATISFACTION AND DISCHARGE
 
     The Company may discharge its payment obligations under the Indenture while
Notes remain outstanding if (a) all outstanding Notes have become due and
payable or will become due and payable at their scheduled maturity within one
year, (b) all outstanding Notes are scheduled for redemption within one year or
(c) all outstanding Notes are delivered to the Trustee for conversion in
accordance with the Indenture and in the case of (a) or (b) above, the Company
has deposited with the Trustee an amount sufficient to pay and discharge the
entire indebtedness on all outstanding Notes on the date of their scheduled
maturity or the scheduled date of redemption (sec. 401).
 
GOVERNING LAW
 
     The Indenture and the Notes will be governed by and construed in accordance
with the laws of the State of New York. (sec. 112)
 
THE TRUSTEE
 
     In case an Event of Default shall occur (and shall not be cured), the
Trustee will be required to use the degree of care of a prudent person in the
conduct of his own affairs in the exercise of its powers. Subject to such
provisions, the Trustee will be under no obligation to exercise any of its
rights or powers under the Indenture at the request of any of the Holders of
Notes, unless they shall have offered to the Trustee reasonable security or
indemnity. (sec.sec. 601 and 603)
 
BOOK-ENTRY
 
     The Notes will be issued in the form of a global note (the "Global Note")
deposited with, or on behalf of, DTC and registered in the name of Cede & Co. as
DTC's nominee. Owners of beneficial interests in the Notes represented by the
Global Note will hold such interests pursuant to the procedures and practices of
DTC and must exercise any rights in respect of their interests (including any
right to convert or require repurchase of their interests) in accordance with
those procedures and practices. Such beneficial owners will not be Holders, and
will not be entitled to any rights under the Global Note or the Indenture, with
respect to the Global Note and the Company and the Trustee, and any of their
respective agents, may treat DTC as the sole Holder and owner of the Global
Note.
 
     DTC has advised the Company as follows: DTC is a limited-purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York Uniform
Commercial Code, and a "clearing agency" registered pursuant to the provisions
of Section 17A of the Exchange Act. DTC holds securities that its participants
deposit with DTC. DTC also facilitates the settlement among participants of
securities transactions, such as transfers and pledges, in deposited securities
through electronic computerized book-entry changes in participants' accounts,
thereby eliminating the need for physical movement of securities certificates.
Direct participants include securities brokers and dealers (including Goldman,
Sachs & Co.), banks, trust companies, clearing corporations, and certain other
organizations. DTC is owned by a number of its direct participants and by the
New York Stock Exchange, Inc., the American Stock Exchange, Inc., and the
National Association of Securities Dealers, Inc. Access to the DTC system is
also available to others such as securities brokers and dealers, banks, and
trust companies that clear through or maintain a custodial relationship with a
direct
 
                                       47
<PAGE>   49
 
participant, either directly or indirectly. The rules applicable to DTC and its
participants are on file with the Securities and Exchange Commission.
 
     Unless and until they are exchanged in whole or in part for certificated
Notes in definitive form as set forth below, the Global Note may not be
transferred except as a whole by DTC to a nominee of DTC, or by a nominee of DTC
to DTC or another nominee of DTC.
 
     The Notes represented by the Global Note will not be exchangeable for
certificated Notes, provided that if DTC is at any time unwilling, unable or
ineligible to continue as depositary and a successor depositary is not appointed
by the Company within 90 days, the Company will issue individual Notes in
definitive form in exchange for the Global Note. In addition, the Company may at
any time and in its sole discretion determine not to have a Global Note, and, in
such event, will issue individual Notes in definitive form in exchange for the
Global Note previously representing all such Notes. In either instance, an owner
of a beneficial interest in a Global Note will be entitled to physical delivery
of Notes in definitive form equal in principal amount to such beneficial
interest and to have such Notes registered in its name. Individual Notes so
issued in definitive form will be issued in denominations of $1,000 and any
larger amount that is an integral multiple of $1,000 and will be issued in
registered form only, without coupons.
 
     Payments of principal of and interest on the Notes will be made by the
Company through the Trustee to DTC or its nominee, as the case may be, as the
registered owner of the Global Note. Neither the Company nor the Trustee will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests of the Global Note
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. The Company expects that DTC, upon receipt of
any payment of principal or interest in respect of the Global Note, will credit
the accounts of the related participants with payment in amounts proportionate
to their respective holdings in principal amount of beneficial interest in the
Global Note as shown on the records of DTC. The Company also expects that
payments by participants to owners of beneficial interests in the Global Note
will be governed by standing customer instructions and customary practices, as
is now the case with securities held for the accounts of customers in bearer
form or registered in "street name," and will be the responsibility of such
participants.
 
     So long as the Notes are represented by a Global Note, DTC or its nominee
will be the only entity that can exercise a right to repayment pursuant to the
Holder's option to elect repayment of its Notes or the right of conversion of
the Notes. Notice by participants or by owners of beneficial interests in a
Global Note held through such participants of the exercise of the option to
elect repayment, or the right of conversion, of beneficial interests in Notes
represented by the Global Note must be transmitted to DTC in accordance with its
procedures on a form required by DTC and provided to participants. In order to
ensure that DTC's nominee will timely exercise a right to repayment, or the
right of conversion, with respect to a particular Note, the beneficial owner of
such Notes must instruct the broker or other participant through which it holds
an interest in such Notes to notify DTC of its desire to exercise a right to
repayment, or the right of conversion. Different firms have different cut-off
times for accepting instructions from their customers and, accordingly, each
beneficial owner should consult the broker or other participant through which it
holds an interest in a Note in order to ascertain the cut-off time by which such
an instruction must be given in order for timely notice to be delivered to DTC.
The Company will not be liable for any delay in delivery of such notice to DTC.

COMMON STOCK
 
     The holders of Common Stock are entitled to one vote for each share held of
record on all matters submitted to a vote of stockholders, except stockholders
may cumulate their votes in the election of directors. Subject to preferences
that may be applicable to any outstanding Preferred Stock, the holders of Common
Stock are entitled to receive ratably such dividends, if any, as may be declared
from time to time by the Company's Board of Directors out of funds legally
available for that purpose. 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, subject to prior
distribution rights of Preferred Stock, if any, then outstanding. The Common
Stock has no preemptive or conversion rights or other subscription rights. There
are no redemption or sinking fund provisions applicable to the Common Stock.
 
PREFERRED SHARES RIGHTS AGREEMENT
 
     Pursuant to the Preferred Shares Rights Agreement (the "Rights Agreement")
dated as of August 16, 1994, as amended, between the Company and Chemical Trust
Company of California, as Rights Agent (the "Rights Agent"), the Company's Board
of Directors declared a dividend of one right (a "Right") to purchase one
one-thousandth share of the Company's Series A Participating Preferred Stock
("Series A Preferred") for each outstanding share of Common Stock ("Common
Shares") of the Company. The dividend was payable on August 31, 1994 (the
"Record Date") to stockholders of record as of the close of business on that
date. Each Right entitles the registered holder to purchase from the Company one
one-thousandth of a share of Series A Preferred at an exercise price of $100.00
(the "Purchase Price"), subject to adjustment.
 
     The following summary of the principal terms of the Rights Agreement is a
general description only and is subject to the detailed terms and conditions of
the Rights Agreement. A copy of the Rights Agreement is filed as an Exhibit to
the Registration Statement of which this Prospectus is a part.
 
     Rights Evidenced by Common Share Certificates.  The Rights will not be
exercisable until the Distribution Date (defined below). Certificates for the
Rights ("Rights Certificates") will not be sent to stockholders and the Rights
will attach to and trade only together with the Common Shares. Accordingly,
Common Share certificates outstanding on the Record Date will evidence the
Rights related thereto, and Common Share certificates issued after the Record
Date will contain a notation incorporating the Rights Agreement by reference.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
the surrender or transfer of any certificates for Common Shares, outstanding as
of the Record Date, even without notation or a copy of the Summary of Rights
being attached thereto, will also constitute the transfer of the Rights
associated with the Common Shares represented by such certificate.
 
     Distribution Date.  The Rights will separate from the Common Shares, Rights
Certificates will be issued and the Rights will become exercisable upon the
earlier of: (i) 10 days (or such later date as may be determined by a majority
of the Board of Directors, excluding directors affiliated with the Acquiring
Person, as defined below (the "Continuing Directors")) following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has acquired, or obtained the right to acquire, beneficial
ownership of 15% or more of the outstanding Common Shares, or (ii) 10 business
days (or such later date as may be determined by a majority of the Continuing
Directors) following the commencement of, or announcement of an intention to
make, a tender offer or exchange offer the consummation of which would result in
the beneficial ownership by a person or group of 15% or more of the outstanding
Common Shares. The earlier of such dates is referred to as the "Distribution
Date."
 
     Issuance of Rights Certificates; Expiration of Rights.  As soon as
practicable following the Distribution Date, separate Rights Certificates will
be mailed to holders of record of the Common Shares as of the close of business
on the Distribution Date and such separate Rights Certificates alone will
evidence the Rights from and after the Distribution Date. All Common Shares
issued prior to the Distribution Date will be issued with Rights. Common Shares
issued after the Distribution Date may be issued with Rights if such shares are
issued (i) upon the conversion of outstanding convertible debentures or any
other convertible securities issued after adoption of the Rights Agreement or
(ii) pursuant to the exercise of
 
                                       49
<PAGE>   51
 
stock options or under employee benefit plans or arrangements unless such
issuance would result in (or create a risk that) such options, plans or
arrangements would not qualify for otherwise available special tax treatment.
Except as otherwise determined by the Board of Directors, no other Common Shares
issued after the Distribution Date will be issued with Rights. The Rights will
expire on the earliest of (i) August 16, 2004 (the "Final Expiration Date"),
(ii) redemption or exchange of the Rights as described below, or (iii)
consummation of an acquisition of the Company satisfying certain conditions by a
person who acquired shares pursuant to a Permitted Offer as described below.
 
     Initial Exercise of the Rights.  Following the Distribution Date, and until
one of the further events described below, holders of the Rights will be
entitled to receive, upon exercise and the payment of $100.00 per Right, one
one-thousandth share of the Series A Preferred. In the event that the Company
does not have sufficient Series A Preferred available for all Rights to be
exercised, or the Board decides that such action is necessary and not contrary
to the interests of Rights holders, the Company may instead substitute cash,
assets or other securities for the Series A Preferred for which the Rights would
have been exercisable under this provision or as described below.
 
     Right to Buy Company Common Shares.  Unless the Rights are earlier
redeemed, in the event that an Acquiring Person becomes the beneficial owner of
15% or more of the Company's Common Shares then outstanding (other than pursuant
to a Permitted Offer), then proper provision will be made so that each holder of
a Right which has not theretofore been exercised (other than Rights beneficially
owned by the Acquiring Person, which will thereafter be void) will thereafter
have the right to receive, upon exercise, Common Shares having a value equal to
two times the Purchase Price. Rights are not exercisable following the
occurrence of an event as described above until such time as the Rights are no
longer redeemable by the Company as set forth below.
 
     Right to Buy Acquiring Company Stock.  Similarly, unless the Rights are
earlier redeemed, in the event that, after the Shares Acquisition Date (as
defined below), (i) the Company is acquired in a merger or other business
combination transaction, or (ii) 50% or more of the Company's consolidated
assets or earning power are sold (other than in transactions in the ordinary
course of business), proper provision must be made so that each holder of a
Right which has not theretofore been exercised (other than Rights beneficially
owned by the Acquiring Person, which will thereafter be void) will thereafter
have the right to receive, upon exercise, shares of common stock of the
acquiring company having a value equal to two times the Purchase Price (unless
the transaction satisfies certain conditions and is consummated with a person
who acquired shares pursuant to a Permitted Offer, in which case the Rights will
expire).
 
     Permitted Offer.  A Permitted Offer means a tender offer for all
outstanding Common Shares that has been determined by a majority of the
Continuing Directors to be adequate and otherwise in the best interests of the
Company and its stockholders. Where the Board of Directors has determined that a
tender offer constitutes a Permitted Offer, the Rights will not become
exercisable to purchase Common Shares or shares of the acquiring company (as the
case may be) at the discounted price described above.
 
     Exchange Provision.  At any time after the acquisition by an Acquiring
Person of 15% or more of the Company's outstanding Common Shares and prior to
the acquisition by such Acquiring Person of 50% or more of the Company's
outstanding Common Shares, the Board of Directors of the Company may exchange
the Rights (other than Rights owned by the Acquiring Person), in whole or in
part, at an exchange ratio of one Common Share per Right.
 
     Redemption.  At any time on or prior to the close of business on the
earlier of (i) the 10th day following the acquisition by an Acquiring Person
(the "Share Acquisition Date") or such later date as may be determined by a
majority of the Continuing Directors and publicly announced by the Company, or
(ii) the Final Expiration Date of the Rights, the Company may redeem the Rights
in whole, but not in part, at a price of $.01 per Right.
 
                                       50
<PAGE>   52
 
     Adjustments to Prevent Dilution.  The Purchase Price payable, the number of
Rights, and the number of Series A Preferred or Common Shares or other
securities or property issuable upon exercise of the Rights are subject to
adjustment from time to time in connection with the dilutive issuances by the
Company as set forth in the Rights Agreement. With certain exceptions, no
adjustment in the Purchase Price will be required until cumulative adjustments
require an adjustment of at least 1% in such Purchase Price.
 
     Cash Paid Instead of Issuing Fractional Shares.  No fractional portion less
than integral multiples of one Common Share will be issued upon exercise of a
Right and in lieu thereof, an adjustment in cash will be made based on the
market price of the Common Shares on the last trading date prior to the date of
exercise.
 
     No Stockholders' Rights Prior to Exercise.  Until a Right is exercised, the
holder thereof, as such, will have no rights as a stockholder of the Company
(other than any rights resulting from such holder's ownership of Common Shares),
including, without limitation, the right to vote or to receive dividends.
 
     Amendment of Rights Agreement.  The provisions of the Rights Agreement may
be supplemented or amended by the Board of Directors in any manner prior to the
close of business on the Distribution Date without the approval of Rights
holders. After the Distribution Date, the provisions of the Rights Agreement may
be amended by the Board in order to cure any ambiguity, defect or inconsistency,
to make changes which do not adversely affect the interests of holders of Rights
(excluding the interests of any Acquiring Person), or to shorten or lengthen any
time period under the Rights Agreement; provided, however, that no amendment to
adjust the time period governing redemption shall be made at such time as the
Rights are not redeemable.
 
     Rights and Preferences of the Series A Preferred.  Series A Preferred
purchasable upon exercise of the Rights will not be redeemable. Each share of
Series A Preferred will be entitled to an aggregate dividend of 1,000 times the
dividend declared per Common Share. In the event of liquidation, the holders of
the Series A Preferred will be entitled to a minimum preferential liquidation
payment equal to the greater of (i) $1,000 per share or (ii) 1,000 times the per
share amount to be distributed to the holders of the Common Shares. Each share
of Series A Preferred will have 1,000 votes, voting together with the Common
Shares. In the event of any merger, consolidation or other transaction in which
the Common Shares are changed or exchanged, each share of Series A Preferred
will be entitled to receive 1,000 times the amount received per Common Share.
These rights are protected by customary anti-dilution provisions.
 
     Because of the nature of the dividend, liquidation and voting rights of the
shares of Series A Preferred, the value of the one one-thousandth interest in a
share of Series A Preferred purchasable upon exercise of each Right should
approximate the value of one Common Share.
 
     Certain Anti-Takeover Effects.  The Rights approved by the Board are
designed to protect and maximize the value of the outstanding equity interests
in the Company in the event of an unsolicited attempt by an acquiror to take
over the Company, in a manner or on terms not approved by the Board of
Directors. Takeover attempts frequently include coercive tactics to deprive the
Company's Board of Directors and its stockholders of any real opportunity to
determine the destiny of the Company or to evaluate and protect the long-term
value of the Company. The Rights are not intended to prevent a takeover of the
Company. The Rights may be redeemed by the Company at $.01 per Right within ten
days (or such later date as may be determined by a majority of the Board of
Directors, excluding directors affiliated with an Acquiring Person) after the
accumulation of 15% or more of the Company's shares by a single acquiror or
group. Accordingly, the Rights should not interfere with any merger or business
combination approved by the Board of Directors.
 
     Issuance of the Rights does not in any way weaken the financial strength of
the Company or interfere with its business plans. The issuance of the Rights
themselves has no dilutive effect, will not affect reported earnings per share,
should not be taxable to the Company or to its stockholders, and will not change
the way in which the Company's shares are presently traded. The Company's Board
of Directors
 
                                       51
<PAGE>   53
 
believes that the Rights represent a sound and reasonable means of addressing
the complex issues of corporate policy created by the current takeover
environment.
 
     However, the Rights may have the effect of rendering more difficult or
discouraging an acquisition of the Company deemed undesirable by the Board of
Directors. The Rights may cause substantial dilution to a person or group that
attempts to acquire the Company on terms or in a manner not approved by the
Company's Board of Directors, except pursuant to an offer conditioned upon the
negation, purchase or redemption of the Rights.
 
CHARTER AND OTHER PROVISIONS RELATING TO A CHANGE OF CONTROL
 
     Certain provisions of the Certificate of Incorporation and Bylaws of the
Company may be considered to have antitakeover implications. Such provisions
could discourage certain attempts to obtain control of the Company, even though
such attempts might be beneficial to the Company and its stockholders.
 
     Nominations of Director Candidates and Introduction of Business at
Stockholder Meetings.  The Bylaws of the Company contain an advance notice
procedure with regard to the nomination, other than by or at the direction of
the Board of Directors, of candidates for election as directors (the "Nomination
Procedure") and with regard to certain matters to be brought before any meeting
of stockholders (the "Business Procedure"). The Nomination Procedure provides
that only persons nominated by or at the direction of the Board of Directors or
by a stockholder who has given timely written notice in proper form to the
Secretary of the Company prior to the meeting, will be eligible for election as
directors. The Business Procedure provides that at a meeting of stockholders
only such business may be conducted as has been brought before the meeting by or
at the direction of the Board of Directors or by a stockholder who has given
timely written notice in proper form to the Secretary of the Company prior to
the meeting of such stockholder's intention to bring business before the
meeting.
 
     Authorized Stock.  The Certificate of Incorporation of the Company
authorizes 5,000,000 shares of Preferred Stock, with a par value of $.001 per
share. The Certificate of Incorporation authorizes the Board of Directors to fix
without further vote or action by the stockholders the designation, powers,
preferences, and rights of the shares of each series of Preferred Stock and the
qualifications, limitations or restrictions thereof including, but not limited
to, dividend rights, conversion privileges, voting rights, terms of redemption
and liquidation preferences.
 
     Monetary Liability of Directors.  The Certificate of Incorporation of the
Company provides that to the fullest extent permitted by Delaware law, no
director of the Company shall be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director.
The Certificate of Incorporation also incorporates any future amendments to
Delaware law with respect to the elimination of such liability.
 
     Section 203 of the Delaware Corporation Law.  The Company is subject to
Section 203 of the Delaware General Corporation Law (the "DGCL") which, subject
to certain exceptions, prohibits a Delaware corporation from engaging in a
business combination (as defined therein) with an "interested stockholder"
(defined generally as any person who beneficially owns 15% or more of the
outstanding voting stock of the Company or any person affiliated with such
person) for a period of three years following the time that such stockholder
became an interested stockholder, unless (i) prior to such time the Board of
Directors of the corporation approved either the business combination or the
transaction that resulted in the stockholder becoming an interested stockholder;
(ii) upon consummation of the transaction that resulted in the stockholder
becoming an interested stockholder, the interested stockholder owned at least
85% of the voting stock of the corporation at the time the transaction commenced
(excluding for purposes of determining the number of shares outstanding those
shares owned (x) by directors who are also officers of the corporation and (y)
by employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer); or (iii) at or subsequent to such time
the business combination is approved by the Board of Directors of the
corporation and authorized at a meeting of
 
                                       52
<PAGE>   54
 
stockholders by the affirmative vote of at least 66 2/3% of the outstanding
voting stock of the corporation not owned by the interested stockholder.
 
     Other Restrictions.  The Company's cross-licenses with Medtronic,
Teletronics and CPI also contain restrictions that may have the effect of
preventing or substantially impeding an acquisition or change of control of, or
certain minority investments in, the Company. See "Risk Factors -- Significant
Restrictions on Change of Control and Certain Minority Investments."
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a summary of certain United States federal income tax
considerations relating to the purchase, ownership and disposition of the Notes
and of Common Stock into which Notes may be converted, but does not purport to
be a complete analysis of all the potential tax considerations relating thereto.
This summary is based on laws, regulations, rulings and decisions now in effect,
all of which are subject to change. This summary deals only with holders that
will hold Notes and Common Stock into which Notes may be converted as "capital
assets" (within the meaning of Section 1221 of the Internal Revenue Code of
1986, as amended (the "Code")) and does not address tax considerations
applicable to investors that may be subject to special tax rules, such as banks,
tax-exempt organizations, insurance companies, dealers in securities or
currencies, or persons that will hold Notes as a position in a hedging
transaction, "straddle" or "conversion transaction" for tax purposes. This
summary discusses the tax considerations applicable to the initial purchasers of
the Notes who purchase the Notes at their "issue price" as defined in Section
1273 of the Code and does not discuss the tax considerations applicable to
subsequent purchasers of the Notes. The Company has not sought any ruling from
the Internal Revenue Service with respect to the statements made and the
conclusions reached in the following summary, and there can be no assurance that
the Internal Revenue Service will agree with such statements and conclusions.
 
     INVESTORS CONSIDERING THE PURCHASE OF NOTES SHOULD CONSULT THEIR OWN TAX
ADVISORS WITH RESPECT TO THE APPLICATION OF THE UNITED STATES FEDERAL INCOME AND
ESTATE TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES
ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION OR
UNDER ANY APPLICABLE TAX TREATY.
 
PAYMENT OF INTEREST
 
     Interest on a Note generally will be includable in the income of a Holder
as ordinary income at the time such interest is received or accrued, in
accordance with such Holder's method of accounting for United States federal
income tax purposes.
 
SALE, EXCHANGE OR REDEMPTION OF THE NOTES
 
     Upon the sale, exchange or redemption of a Note, a Holder generally will
recognize capital gain or loss equal to the difference between (i) the amount of
cash proceeds and the fair market value of any property received on the sale,
exchange or redemption (except to the extent such amount is attributable to
accrued interest income not previously included in income which is taxable as
ordinary income) and (ii) such Holder's adjusted tax basis in the Note. A
Holder's adjusted tax basis in a Note generally will equal the cost of the Note
to such Holder. Such capital gain or loss will be long-term capital gain or loss
if the Holder's holding period in the Note is more than one year at the time of
sale, exchange or redemption.
 
CONVERSION OF THE NOTES
 
     A Holder generally will not recognize any income, gain or loss upon
conversion of a Note into Common Stock except with respect to cash received in
lieu of a fractional Share of Common Stock. A Holder's tax basis in the Common
Stock received on conversion of a Note will be the same as such Holder's
adjusted tax basis in the Note at the time of conversion (reduced by any basis
allocable to a
 
                                       53
<PAGE>   55
 
fractional share interest), and the holding period for the Common Stock received
on conversion will generally include the holding period of the Note converted.
 
     Cash received in lieu of a fractional share of Common Stock upon conversion
will be treated as a payment in exchange for the fractional share of Common
Stock. Accordingly, the receipt of cash in lieu of a fractional share of Common
Stock generally will result in capital gain or loss (measured by the difference
between the cash received for the fractional share and the Holder's adjusted tax
basis in the fractional share).
 
DIVIDENDS
 
     Dividends paid on the Common Stock generally will be includable in the
income of a Holder as ordinary income to the extent of the Company's current or
accumulated earnings and profits.
 
     If at any time (i) the Company makes a distribution of cash or property to
its stockholders or purchases Common Stock and such distribution or purchase
would be taxable to such stockholders as a dividend for United States federal
income tax purposes (e.g., distributions of evidences of indebtedness or assets
of the Company, but generally not stock dividends or rights to subscribe for
Common Stock) and, pursuant to the antidilution provisions of the Indenture, the
conversion rate of the Notes is increased, or (ii), the conversion rate of the
Notes is increased at the discretion of the Company, such increase in conversion
rate may be deemed to be the payment of a taxable dividend to Holders of Notes
(pursuant to Section 305 of the Code). Holders of Notes could therefore have
taxable income as a result of an event pursuant to which they received no cash
or property.
 
SALE OF COMMON STOCK
 
     Upon the sale or exchange of Common Stock, a Holder generally will
recognize capital gain or loss equal to the difference between (i) the amount of
cash and the fair market value of any property received upon the sale or
exchange and (ii) such Holder's adjusted tax basis in the Common Stock. Such
capital gain or loss will be long-term if the Holder's holding period in Common
Stock is more than one year at the time of the sale or exchange. A Holder's
basis and holding period in Common Stock received upon conversion of a Note are
determined as discussed above under "-- Conversion of the Notes."
 
INFORMATION REPORTING AND BACKUP WITHHOLDING TAX
 
     In general, information reporting requirements will apply to payments of
principal, premium, if any, and interest on a Note, payments of dividends on
Common Stock, payments of the proceeds of the sale of a Note and payments of the
proceeds of the sale of Common Stock to certain noncorporate Holders, and a 31%
backup withholding tax may apply to such payments if the Holder (i) fails to
furnish or certify his correct taxpayer identification number to the payor in
the manner required, (ii) is notified by the Internal Revenue Service (the
"IRS") that he has failed to report payments of interest and dividends properly,
or (iii) under certain circumstances, fails to certify that he has not been
notified by the IRS that he is subject to backup withholding for failure to
report interest and dividend payments. Any amounts withheld under the backup
withholding rules from a payment to a Holder will be allowed as a credit against
such Holder's United States federal income tax and may entitle the Holder to a
refund, provided that the required information is furnished to the IRS.
 
                                  UNDERWRITING
 
     Subject to the terms and conditions set forth in the Underwriting
Agreement, the Company has agreed to sell to Goldman, Sachs & Co. ("Goldman
Sachs" or the "Underwriter"), and Goldman Sachs have agreed to purchase, the
entire principal amount of the Notes.
 
     Under the terms and conditions of the Underwriting Agreement, Goldman Sachs
are committed to take and pay for all of the Notes, if any are taken.
 
                                       54
<PAGE>   56
 
     The Company has granted the Underwriter an option exercisable for 30 days
after the date of this Prospectus to purchase up to an aggregate of $10,000,000
additional principal amount of Notes solely to cover over-allotments, if any.
 
     Goldman Sachs propose to offer the Notes in part directly to the public at
the initial public offering price set forth on the cover page of this Prospectus
and in part to certain securities dealers at such price less a concession of
     % of the principal amount of the Notes. Goldman Sachs may allow, and such
dealers may reallow, a concession not to exceed      % of the principal amount
of the Notes to certain brokers and dealers. After the Notes are released for
sale to the public, the offering price and other selling terms may from time to
time be varied by Goldman Sachs.
 
     The Notes are a new issue of securities with no established trading market.
The Company has been advised by Goldman Sachs that they intend to make a market
in the Notes but are not obligated to do so and may discontinue market making at
any time without notice. No assurance can be given as to the liquidity of the
trading market for the Notes.
 
     The Company has also agreed that it will not offer to sell, contract to
sell or otherwise dispose of any Common Stock (other than upon conversion of the
Notes), any securities substantially similar to the Notes or the Common Stock or
any security exchangeable or exercisable for or convertible into Common Stock or
substantially similar securities (any such security, a "Covered Security"),
without the prior consent of the Underwriter, for a period of 90 days after the
date of this Prospectus, except pursuant to the Company's stock option or
purchase plans existing as of the date of this Prospectus or other options
granted by the Company to employees. Certain directors and executive officers of
the Company have also agreed, subject to certain exceptions, that they will not
offer to sell, sell or otherwise dispose of shares of Common Stock beneficially
owned by them without the prior written consent of the Underwriter until the
earlier of (i) the 90th day after the date of this Prospectus and (ii) such time
as such individual ceases to be an employee and/or director or the Company.
 
     The Underwriter has performed investment banking services for the Company
for which it has received customary compensation.
 
     The Company has agreed to indemnify the Underwriter against certain
liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
     The validity of the Notes and the Common Stock issuable on conversion
thereof will be passed upon for the Company by Wilson Sonsini Goodrich & Rosati,
Professional Corporation, Palo Alto, California and for the Underwriter by
Sullivan & Cromwell, Los Angeles, California.

     The consolidated financial statements of Ventritex, Inc. at June 30, 1994
and 1995, and for each of the three years in the period ended June 30, 1995
appearing in this Prospectus and Registration Statement and incorporated by

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Ventritex, Inc.
 
     We have audited the accompanying consolidated balance sheets of Ventritex,
Inc. as of June 30, 1995 and 1994, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended June 30, 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Ventritex, Inc. at June 30, 1995 and 1994, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
June 30, 1995, in conformity with generally accepted accounting principles.

                                   UNAUDITED)
 
NOTE 1:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Business -- Ventritex, Inc. (the "Company") designs, develops, manufactures
and sells implantable defibrillators and related products for the treatment of
ventricular tachycardia and ventricular fibrillation. On December 28, 1994, the
Company changed its state of incorporation from California to Delaware.
 
     Basis of Presentation -- The accompanying consolidated financial statements
include the Company and its wholly owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated.
 
     Interim Financial Information -- The financial information at March 31,
1996 and for the nine months ended March 31, 1995 and 1996 is unaudited but
includes, in the opinion of management, all adjustments (consisting only of
normal recurring accruals) which the Company considers necessary for a fair
presentation of the financial position at such date and the operating results
and cash flows for those periods. Results for the nine months ended March 31,
1996 are not necessarily indicative of results for the entire year.
 
     Cash Equivalents -- The Company considers all highly liquid investments
with a maturity of three months or less when purchased to be cash equivalents.
 
     Investments -- The Company invests in short-term debt securities consisting
of commercial paper with maturities of less than six months and overnight
deposits (including repurchase agreements for which, due to their short term
nature, the Company normally does not take possession of the underlying
securities). Due to the short duration to maturity, the cost basis of these
securities materially approximate their fair market value. By policy, all
investments have a minimum short-term investment rating of rated A-1 or P-1. As
of June 30, 1995, no single issuer represented greater than 7.5% of total
investments.
 
     In 1995, the Company adopted the provisions of SFAS No. 115, and has
accordingly classified all investments as "available-for-sale".
Available-for-sale securities are carried at fair value based upon quoted market
prices, with the unrealized gains and losses reported in a separate component of
stockholders' equity. The effect of implementing SFAS No. 115 was not material.
 
     Inventory -- Inventories are valued at the lower of cost (first-in,
first-out method) or market.
 
     Equipment and Leasehold Improvements -- Equipment, including capital
equipment leases, and leasehold improvements are carried at cost less
accumulated depreciation and amortization. Equipment is depreciated by the
straight-line method over estimated useful lives of three to seven years.
Leasehold improvements are amortized by the straight-line method over the
shorter of the life of the related asset or the term of the lease. Depreciation
expense includes amortization of capital leases and leasehold improvements.
 
     Warranty -- The Company warrants its implantable defibrillator for three
years or 100 high voltage capacitor charges. A provision for future warranty
costs is recorded based on management estimates.
 
     Revenue Recognition -- Revenue from sales of the Company's products is
recognized upon receipt of a purchase order and shipment of the product.
 
     Net Income (Loss) Per Share -- Net income (loss) per share is computed
using the weighted average number of shares of common stock outstanding and
common equivalent shares, if dilutive.

are comprised of the following:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Under the 1995 Stock Option Plan, the Company may grant incentive stock
options and non-statutory stock options to employees and consultants. Options
may be granted to purchase common stock at exercise prices that will be no less
than the fair market value of the stock at the grant date, as determined by the
Board of Directors, and with terms of five to ten years. The options generally
become exercisable over four years from the date of grant. Subject to
stockholder approval, 1,750,000 shares were authorized under this plan.
 
     Under the Director Option Plan, non-employee directors of the Company
("Outside Directors") receive nondiscretionary, automatic option grants
exercisable for 15,000 shares upon their initial election to the Board of
Directors and on July 1 of each year thereafter exercisable for 5,000 shares,
provided that the first such automatic grant on July 1, 1996 will be exercisable
for 7,500 shares. Options granted to Outside Directors have a term of ten years
from the date of grant and have an exercise price equal to the closing price of
the Company's common stock on the last trading day prior to the date of the
grant. Initial options to Outside Directors become exercisable ratably over 36
months and subsequent annual grants become exercisable ratably over twelve
months. Subject to stockholder approval, 150,000 shares were authorized under
this plan.

     Realization of deferred tax assets is dependent on future earnings, if any,
the timing and amount of which are uncertain. Accordingly, a valuation
allowance, in an amount equal to the net deferred tax asset as of June 30, 1994
and 1995, has been established to reflect these uncertainties.
 
     Approximately $10,311,000 of the deferred tax assets subject to the
valuation allowance at June 30, 1995 relates to the tax benefits of stock option
deductions. These benefits, when realized, will be credited directly to
stockholders' equity and will not reduce the provision for income taxes. The
change in valuation allowance was a net increase of $557,000 and $1,028,000 for
fiscal years 1994 and 1995, respectively.
 
     At June 30, 1995, the Company has net operating loss and research and
development tax credit carryforwards for federal tax purposes of approximately
$49,736,000 and $2,806,000, respectively, that will expire through 2010 if not
utilized. In addition, the Company has a federal minimum tax credit carryover of
$454,000 and a California investment tax credit carryforward of $87,000.
 
NOTE 7:  LITIGATION
 
     The Company is currently in litigation with one of its competitors,
Intermedics, Inc. ("Intermedics"). In response to threats from Intermedics, the
Company filed a declaratory judgment action in the U.S.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
District Court in the Northern District of California in January 1993, asking
the court to declare that certain patents which Intermedics had asserted were
being infringed by the Company were, in fact, invalid, unenforceable or not
infringed. Intermedics then filed several actions in the U.S. District Court in
the Southern District of Texas alleging infringement by the Company of nine
Intermedics patents. Until recently, this litigation has been focused on
procedural issues relating to whether the dispute would be tried in California
or Texas. On October 12, 1994, the U.S. District Court for the Northern District
of California denied Intermedics' motion to transfer Ventritex's pending suits
to Texas and granted Ventritex's motion to enjoin Intermedics from further
prosecution of its aforementioned suits in Texas. The U.S. District Court for
the Southern District of Texas thereafter issued an order transferring to
California all of the Texas cases which Intermedics had served upon Ventritex.
The Court has indicated that the trial in connection with the above-described
actions will begin in October 1996.
 
     The Company filed a further action in the Northern District of California
in July 1993 seeking a declaratory judgment that the patents that Intermedics
has asserted against the Company are not infringed by Ventritex, are invalid and
are unenforceable. This action, which was filed against Intermedics, its parent
and affiliate companies, SulzerMedica and Sulzer, Inc., seeks damages based upon
claims for antitrust law violations, malicious prosecution, conspiracy and
breach of contract. Intermedics, SulzerMedica and Sulzer, Inc. have moved to
stay or dismiss the Company's damage claims, and a Special Master has recently
recommended that certain of these claims be dismissed with leave to amend and
that others be stayed pending determination of other issues in the parties'
various lawsuits. The Court has not yet ruled upon these motions.
 
     In initial pleadings filed in the above actions, Intermedics sought
judgments against Ventritex for damages, attorneys' fees and injunctive relief.
It is expected that Intermedics will, during the course of the litigation, seek
to obtain various types of pretrial relief which include, but are not limited
to, summary judgments, dismissals of Ventritex's claims and preliminary
injunctions. In January 1995, Intermedics filed a motion for partial summary
judgment and for issuance of a preliminary injunction based on alleged
infringement of one of its patents. Ventritex has vigorously contested these
motions and has requested the U.S. Patent and Trademark Office to conduct a
re-examination of the Intermedics' patent upon which these motions are based.
The Patent Office has agreed to conduct a re-examination of this patent. The
Special Master has recommended denial of Intermedics' partial summary judgment
motion. The Court has not yet issued its ruling. No hearing date has been set
for Intermedics' preliminary injunction motion.
 
     In addition to its patent infringement claims, Intermedics has previously
alleged trade secret misappropriation and related acts by the Company and two of
its officers, who were formerly employees of Intermedics. In this lawsuit, the
Company filed counterclaims against Intermedics for infringement of two of
Ventritex's patents. These counterclaims are still pending. Certain of the trade
secret misappropriation and related claims were tried in 1992 before a U.S.
District Court jury in San Francisco. The jury returned a unanimous verdict in
favor of the Company and its officers and found that Intermedics had acted in
bad faith in continuing to pursue the trade secret misappropriation claims. The
Court set aside the bad faith portion of the verdict based on Intermedics' claim
of an erroneous jury instruction. A new trial on the bad faith issue has been
ordered, but no trial date has been set.
 
     In addition to the above-mentioned litigation, the Company is also involved
in other litigation in the normal course of business. Although an adverse
determination in the Intermedics proceedings or in other litigation or
administrative proceedings could have a material adverse effect on the Company,
based upon the nature of the claims made and the investigation completed to
date, the Company believes the outcome of the described actions will not have a
material adverse effect on the financial position or results of operations of
the Company.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
NOTE 8:  EMPLOYEE BENEFIT PLAN
 
     The Company sponsors an employee salary deferral plan that allows voluntary
contributions by employees after completion of six months of service. Eligible
employees may elect to contribute from 3% to 15% of their respective
compensation, and the Company at its discretion may elect to make matching
contributions. During fiscal 1995, the Company matched 50% of the first 6% of an
employee's contributions to a maximum of $1,000 per calendar year. The Company's
fiscal 1995 contribution under this plan was approximately $419,000. In fiscal
1996, the Company will continue to match an employee's contribution on the same
basis to a maximum of 50% of the annual limits on salary deferrals established
by tax regulations.
 
NOTE 9:  CONCENTRATION OF CREDIT RISK
 
     The Company sells primarily to hospitals. In the fiscal years ended June
30, 1994 and 1995, no customer accounted for more than 10% of net sales. The
Company performs ongoing credit evaluations of its customers, but does not
require collateral. The Company maintains reserves for potential credit losses,
and to date such losses have been within management's expectations.
 
NOTE 10:  INTELLECTUAL PROPERTY AGREEMENTS
 
     In July 1993, the Company entered into litigation settlements and patent
cross-license agreements with two companies in the implantable defibrillator
field. One of the agreements is between Cardiac Pacemakers, Inc., its then
parent company Eli Lilly and Company, and Ventritex. The second agreement is
between Telectronics Pacing Systems, Inc., Telectronics N.V., and Ventritex.
Under the agreement with Cardiac Pacemakers, Ventritex will pay royalties based
on commercial sales of products covered by the licensed patents. In connection
with these agreements, Ventritex recognized a charge of $18,600,000 in fiscal
1993 for one-time payments as well as other related settlement expenses.
 
     The Company's licenses with Medtronic, CPI and Telectronics contain
significant restrictions that may have the effect of preventing or substantially
impeding an acquisition of, change-of-control of, or certain minority
investments in, the Company. Such restrictions include the possible termination
of various licenses to the Company and the requirement that the Company make a
substantial payment to one of the licensors upon such event.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's board of directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Act"). The
Registrant's Restated Certificate of Incorporation and Bylaws provide for the
indemnification of its directors, officers, employees and other agents to the
maximum extent permitted by the Delaware General Corporation Law. In addition,
the Registrant has entered into Indemnification Agreements with its officers and
directors.
 
     Reference is also made to Section 8 of the Underwriting Agreement contained
in Exhibit 1.1 hereto, which provides for indemnification of the Company and
officers, directors and certain controlling persons of the Company by the
Underwriter against certain liabilities.

   ITEM 17. UNDERTAKINGS
 
     Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers, and controlling persons of the Registrant
pursuant to the Delaware General Corporation Law, the Bylaws of the Registrant,
Indemnification Agreements, the Underwriting Agreement, or otherwise, the
Registrant has been advised that, in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer, or controlling
person of the Registrant in the successful defense of any action, suit, or
proceeding) is asserted by such director, officer, or controlling person in
connection with the securities being registered hereunder, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement 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.
 
     The undersigned Registrant hereby further undertakes that:
 
          (1) For purpose of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of a registration statement in reliance upon Rule 430A and contained in the
     form of prospectus filed by the Registrant pursuant to Rule
 
                                      II-2
<PAGE>   75
 
     424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be
     part of the registration statement as of the time it was declared
     effective.
 
    (2)  For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.
