Financial Statements or as otherwise indicated herein, information in this
Prospectus gives effect to (i) the reincorporation of the Company from
California to Delaware effected in January 1998, (ii) the one-for-1.376 reverse
split of the outstanding Common Stock effected in January 1998 and (iii) the
conversion of all outstanding shares of Preferred Stock into shares of Common
Stock, which will occur automatically upon the closing of this offering, and
assumes that the Underwriters' over-allotment option is not exercised. See
"Certain Transactions," "Description of Capital Stock" and "Underwriting." This
Prospectus contains certain statements of a forward-looking nature relating to
future events or the future financial performance of the Company. Prospective
investors are cautioned that such statements are only predictions and that
actual events or results may differ materially. In evaluating such statements,
prospective investors should specifically consider the various factors
identified in this Prospectus, including the matters set forth under the
caption "Risk Factors," which would cause actual results to differ materially
from those indicated by such forward-looking statements.     
 
                                  THE COMPANY
 
  Symphonix is a leader in the development of proprietary semi-implantable and
implantable products, or soundbridges, for the management of moderate to severe
hearing impairment. In 1994, mild to severe hearing impairment affected
approximately 26 million people in the United States, or 10% of the population,
of whom approximately 17 million people were classified as moderately or
severely hearing impaired. The Company believes that its family of Vibrant
soundbridges, designed to overcome the inherent limitations of traditional
hearing devices, represent a novel approach in the management of hearing
impairment. The Company's initial product under development, the Vibrant
soundbridge, is a semi-implantable device which mechanically drives the three
small bones of the middle ear to overcome the user's hearing impairment. The
Company's second generation product, the Vibrant P programmable soundbridge,
provides a greater degree of customization to address the specific needs of a
particular user's hearing loss and expands the types of hearing loss that can
be managed by the Company's products.
 
  The Vibrant soundbridge is designed for the management of moderate to severe
sensorineural hearing impairment. Sensorineural hearing impairment accounts for
the vast majority of adults who are hearing impaired and occurs typically as a
result of aging or exposure to loud noise over a protracted period of time. The
traditional approach to the management of mild to severe sensorineural hearing
impairment has been the use of hearing aids, which were first introduced a
hundred years ago. Hearing aids are acoustic drive devices that amplify sound
to increase the movement of the ear drum, thereby indirectly vibrating the
bones of the middle ear in an attempt to overcome the decreased sensitivity of
the delicate sensory hair cells of the inner ear. Although there have been
continued advancements in hearing aid technology, for optimal performance, all
or part of the device must fit tightly in the ear canal which results in
significant drawbacks, including distorted sound quality, acoustic feedback,
poor localization, social stigma, discomfort and poor reliability. Despite the
inherent limitations of hearing aids, in 1995, approximately 1.7 million
hearing aids were sold in the United States, representing a retail market of
approximately $1.2 billion. The United States market represents approximately
38% of the worldwide hearing aid market. The Company estimates that the
worldwide retail market for hearing aids exceeded $3.0 billion in 1995.
 
  Rather than indirectly driving the ear's vibratory structure, the Vibrant
soundbridge is a direct drive device which incorporates the Company's patented
core technology, the Floating Mass Transducer ("FMT"). The FMT is a tiny
transducer, smaller than a grain of rice, that is attached directly to the
incus bone of the middle ear. The FMT converts sound into mechanical vibrations
and enhances the natural movement of the bones of the middle ear, which in turn
generate enhanced stimulation of the delicate
 
                                       3
<PAGE>
 
   
sensory hair cells of the inner ear. The Company believes that its direct drive
soundbridges offer significant benefits, including improved sound quality and
speech intelligibility, elimination of acoustic feedback, improved sound
localization, minimized social stigma and improved reliability. The Company has
three patents issued in the United States and 21 patents pending in both the
United States and internationally covering a number of fundamental aspects of
the FMT and related technologies.     
 
  The Company is currently developing a family of Vibrant soundbridges,
including the Vibrant D soundbridge, which is designed to permit an even
greater degree of customization along with the additional benefit of digital
signal processing, and the Vibrant HF soundbridge, which is designed to provide
hearing correction to those individuals who have noise-induced hearing loss at
high frequencies but relatively normal hearing at lower frequencies. In
addition, the Company is in the early stage of developing versions of the
Vibrant soundbridge that are totally implantable with no external components.
The Company's soundbridges are designed to be implanted in a single ear in a
two-hour, outpatient procedure which requires surgical techniques similar to
those employed in common middle ear surgical procedures. The Company's strategy
is to market its soundbridges initially to those specialists in otology who are
currently most active in ear surgery and thereafter, to the general population
of Ear, Nose and Throat ("ENT") surgeons. Because the surgical procedure for
implanting the Vibrant soundbridge utilizes many of the same techniques
employed by surgeons trained and experienced in otological procedures, the
Company believes that surgeon training will not be a significant impediment to
market acceptance.
   
  In September 1996, the Company initiated clinical trials of the Vibrant
soundbridge in both the United States and Europe, and in July 1997 the Company
initiated clinical trials of the Vibrant P soundbridge in Europe. As of January
5, 1998, 48 patients have been implanted with the Company's soundbridges of
whom 44 have had the Audio Processor fitted and the soundbridge's performance
evaluated. In 1996, the Company received United States Food and Drug
Administration ("FDA") approval of an Investigational Device Exemption ("IDE")
to commence clinical testing of the Vibrant soundbridge. In the United States,
Phase I testing limited to two sites and five patients has been completed. On
November 14, 1997, the Company filed an IDE supplement summarizing the Phase I
results, finalizing the study protocol and labeling claims, providing technical
information regarding the Vibrant P soundbridge, and requested permission to
proceed to the pivotal study. On December 11, 1997, the FDA approved the multi-
center pivotal study in 55 subjects at up to 12 sites with the second
generation Vibrant P soundbridge.     
   
  The Company has completed its European clinical trial and has submitted the
technical, preclinical and clinical data that it believes will be necessary,
together with the previously obtained certifications, to satisfy the applicable
regulatory requirements for commercial sales in the European Union ("EU").     
 
  The Company's objectives are to establish its family of Vibrant soundbridges
as the standard of care worldwide for the management of moderate to severe
hearing impairment and to establish Symphonix as the leader in the hearing
management market. Key elements of the Company's strategy include:
demonstrating improved quality of life, developing surgeon endorsement of the
Company's family of soundbridges, leveraging the Company's patented core
technology and protecting and enhancing the Company's proprietary position.
   
  The Company was incorporated under the laws of California in May 1994 and was
reincorporated under the laws of Delaware in January 1998. The Company's
principal executive offices are located at 3047 Orchard Parkway, San Jose, CA
95134. Its telephone number is (408) 232-0710.

                                 RISK FACTORS
 
  This Prospectus contains forward-looking statements that involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain
factors, including those set forth in the following risk factors and elsewhere
in this Prospectus. The following principal factors should be carefully
considered in evaluating the Company and its business before purchasing the
Common Stock offered hereby.
   
DEVELOPMENT STAGE COMPANY; HISTORY OF LOSSES AND EXPECTATION OF FUTURE LOSSES
       
  Since the Company's inception in 1994, substantially all of the Company's
resources have been dedicated to research and development, and the Company has
not generated any revenue from product sales. All of the Company's products
are in development and will require additional clinical trials and, in some
cases, additional development and preclinical testing prior to the submission
of a regulatory application for commercial use. Since the Company's products
are currently in development, significant product revenues will not be
realized for at least several years, if ever. The Company is a development
stage company and, at December 31, 1997, had an accumulated deficit of $18.4
million. The Company expects its operating losses to continue at least through
1999 as it continues to expend substantial funds for clinical trials in
support of regulatory approvals, expansion of research and development
activities and establishment of commercial-scale manufacturing and sales and
marketing capabilities. Any commercialization of the Company's products will
require substantial development, clinical, regulatory, manufacturing, sales
and marketing and other expenditures. There can be no assurance that the
Company's soundbridges will be successfully commercialized or that the Company
will achieve significant revenues from either international or domestic sales.
In addition, there can be no assurance that the Company will achieve or
sustain profitability in the future. The Company's results of operations may
fluctuate from quarter to quarter or year to year and will depend upon
numerous factors, including action relating to regulatory matters, progress of
clinical trials, the timing and scope of research and development efforts, the
extent to which the Company's products gain market acceptance or achieve
reasonable reimbursement levels, the timing of scale-up of manufacturing
capabilities, the timing of expansion of sales and marketing activities and
competition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."     
 
LIMITED CLINICAL TESTING EXPERIENCE
   
  The Company has conducted only limited clinical trials of its Vibrant and
Vibrant P soundbridges. The Company has received approval of an IDE to conduct
a clinical trial of the Vibrant and Vibrant P soundbridges, and the Vibrant
soundbridge has been the subject of limited clinical testing in the United
States. The Vibrant and the Vibrant P soundbridges have both been the subject
of limited clinical testing in Europe. None of the Company's other
soundbridges under development have been tested in human clinical trials. The
Company's soundbridges will require additional development, clinical trials
and regulatory approval prior to commercialization. The results from
preclinical studies and early clinical trials may not be indicative of results
obtained in later clinical trials, and there can be no assurance that clinical
trials conducted by the Company will demonstrate sufficient safety and
efficacy to obtain requisite approvals.     
 
  The rate of completion of the Company's clinical trials may be delayed by
many factors, including slower than anticipated patient enrollment or adverse
events occurring during clinical trials. Completion of preclinical and
clinical activities may take several years, and the length of time for
completion of the required studies is unpredictable. In addition, data
obtained from preclinical and clinical activities are susceptible to varying
interpretations, which could delay, limit or prevent regulatory approval. No
assurance can be given that any of the Company's clinical trials will be
successfully completed on a timely basis, or at all, that additional clinical
trials will be allowed by the FDA or other regulatory authorities or that such
clinical trials will commence as planned.
 
                                       6
<PAGE>
 
   
  The Company has submitted clinical data on 28 patients to the Company's
Notified Body, a certification body authorized to test and certify medical
devices for sale in the EU, to demonstrate the safety and performance of the
Vibrant and Vibrant P soundbridges. As of January 5, 1998, 43 patients in the
European clinical trial have been implanted with the Company's soundbridges,
of whom 39 have had the Audio Processor fitted and the soundbridge's
performance evaluated. There can be no assurance that such data will be
accepted by the Company's Notified Body, or that the Notified Body will not
require the Company to obtain additional data from additional clinical trials
involving more patients in order to demonstrate the safety and performance of
the Vibrant and Vibrant P soundbridges. If the Notified Body requires the
Company to submit additional data, the timing of regulatory approval and
commercialization of the Company's products in Europe could be delayed. See
"Business--Government Regulation."     
 
RELIANCE ON FMT TECHNOLOGY
 
  The Company has concentrated its efforts primarily on the development,
implementation and acceptance of the FMT, the patented core direct drive
technology upon which all of the Company's soundbridges are based, and will be
dependent upon the successful development of its soundbridges to generate
revenues. The Company's soundbridges employ a direct drive approach to the
management of hearing impairment, which is a novel development. There can be
no assurance that the Company's soundbridges, based on the Company's FMT
technology, will prove to be safe and effective, or that if proven safe and
effective, can be manufactured at reasonable cost or successfully
commercialized. See "Business--Products Under Development."
 
NO ASSURANCE OF PRODUCT APPROVAL; GOVERNMENT REGULATION
 
  The research, preclinical and clinical activities, manufacturing, labeling,
distribution, sale, marketing, advertising and promotion of the Company's
proposed products are subject to extensive and rigorous government regulation
in the United States and certain other countries. In the United States and
certain other countries, the process of obtaining and maintaining required
regulatory clearances or approvals is lengthy, expensive and uncertain. The
Company's future success will be significantly dependent upon commercial sales
of its products under development. The Company will also not be able to market
such products domestically or overseas until it meets the safety and quality
regulations of each jurisdiction in which the Company, its agents or
distributors seek to sell such products. Noncompliance with applicable FDA
requirements can result in administrative sanctions or judicially imposed
sanctions such as civil penalties, criminal prosecution, injunctions, product
seizure or detention, product recalls, or total or partial suspension of
production. In addition, noncompliance may result in the FDA's refusal to
approve pending applications for marketing approval or clearance or
supplements to approved marketing approvals, or in the withdrawal of marketing
approval.
   
  Before the Company's products can be commercialized in the United States,
the Company must submit, in a premarket approval ("PMA") application,
extensive data on preclinical studies and clinical trials, device design,
manufacturing, labeling, promotion and advertising, as well as other aspects
of the product. In addition, the Company must submit clinical data gathered in
trials conducted under an IDE demonstrating to the satisfaction of the FDA
that the product is safe and effective for its labeling claims, and obtain
marketing approval from the FDA. Phase I of the IDE study has been completed.
Phase I was limited to two sites and five subjects and was intended to test
the safety and provide preliminary evidence of the effectiveness of the device
and the surgical procedure used to implant the device. On November 14, 1997,
the Company filed an IDE supplement summarizing the Phase I results,
finalizing the study protocol and labeling claims, providing technical
information regarding the Vibrant P soundbridge, and requested permission to
proceed to the pivotal study. On December 11, 1997, the FDA approved the
multi-center pivotal study in 55 subjects at up to 12 sites with the second
generation Vibrant P soundbridge. There can be no assurance that the Company's
clinical trial effort will progress as expected, will not be delayed or that
such effort will lead to the successful development of any product. No
assurance can be given that any of the Company's clinical trials will continue
to be allowed by the FDA or other regulatory agencies.     
       
                                       7
<PAGE>
 
  Any delays in the Company's clinical trials would have a material adverse
effect on the Company's business, financial condition and results of
operations. Success in preclinical studies or early stage clinical trials does
not assure success in later stage clinical trials. Data obtained from
preclinical and clinical activities are susceptible to varying interpretations
which could delay, limit or prevent regulatory approval. Further, there can be
no assurance that if such testing of products under development is completed,
any such devices will be accepted for formal review by the FDA or approved by
the FDA for marketing in the United States.
 
  Subsequent to the receipt of an FDA approval, the Company will continue to
be regulated by the FDA with regard to the reporting of adverse events related
to its products, and ongoing Quality System regulation ("QS regulation")
compliance (which includes elaborate testing, control, documentation and other
quality assurance procedures). The Company's manufacturing facility must be
registered with the FDA and the California Food and Drug Branch and will be
subject to periodic inspections by the FDA and by the California Food and Drug
Branch. The timing and requirements of obtaining approval for sale in foreign
countries may differ from that required for FDA approval. In addition, there
may be foreign regulatory barriers other than pre-market approval.
 
  The EU consists of 15 countries encompassing most of the major countries in
Europe. The EU has adopted numerous directives and standards regulating the
design, manufacture, clinical trial, labeling, and adverse event reporting for
medical devices. The principal directives prescribing the laws and regulations
pertaining to medical devices in the EU are the Medical Devices Directive,
93/42/EEC ("MDD") and the Active Implantable Medical Devices Directive,
90/385/EEC ("AIMDD"). In the EU, the Company's soundbridges will be regulated
as active implantables and therefore be governed by the AIMDD. Certain other
countries, such as Switzerland, have voluntarily adopted laws and regulations
that mirror those of the EU with respect to medical devices.
   
  The Company's facilities have been inspected by the Notified Body and its
quality system has been certified by the Notified Body as being in compliance
with the required standards. The Company has submitted the technical,
preclinical and clinical data that it believes will be necessary, together
with the previously obtained certifications, to satisfy the applicable
regulatory requirements for commercial sales in the EU. The Company has
submitted clinical data to its Notified Body on 28 patients to demonstrate the
safety and performance of the Vibrant and Vibrant P soundbridges. As of
January 5, 1998, a total of 43 patients in the European clinical trial have
been implanted (19 with the Vibrant and 24 with the Vibrant P soundbridge) of
whom 39 have had the Audio Processor fitted and the soundbridge's performance
evaluated. There can be no assurance that such data will be accepted by the
Company's Notified Body, or that the Notified Body will not require the
Company to obtain additional data from additional clinical trials involving
more patients in order to demonstrate the safety and performance of the
Vibrant soundbridge and the Vibrant P soundbridge. If the Notified Body
requires the Company to submit additional data, the timing of regulatory
approval and commercialization of the Company's products in Europe could be
delayed.     
 
  Once a manufacturer has satisfactorily completed the regulatory compliance
tasks required by the directives and received favorable determinations by the
Notified Body, it is eligible to place the CE mark on its products.
Manufacturers are subject to ongoing regulation under the AIMDD. The quality
system will be subject to periodic audit and recertification, and serious
adverse events must be reported to the authorities in the country where the
incident takes place. If such incidents occur, the manufacturer may have to
take remedial action, including withdrawal of the product from the EU market.
See "Business--Products Under Development" and "--Government Regulation."
 
NO ASSURANCE OF MARKET ACCEPTANCE
 
  The market acceptance of the Company's soundbridges will depend upon their
acceptance by the medical community and patients as clinically useful,
reliable and cost-effective compared to other
 
                                       8
<PAGE>
 
devices. Clinical acceptance will depend on numerous factors, including the
establishment of the safety and the effectiveness of the soundbridge's ability
to drive the ossicles directly and improve hearing over currently available
hearing aids. Clinical acceptance will also depend on the receipt of
regulatory approvals in the United States and internationally and the
Company's ability to adequately train ear surgeons on the techniques for
implanting the Company's soundbridges. In addition, there can be no assurance
that the Company's soundbridges will be preferable alternatives to existing
devices, some of which, such as the acoustic hearing aid, do not require
surgery, or that the Company's soundbridges will not be rendered obsolete or
noncompetitive by products under development by other companies. Patient
acceptance of the Company's soundbridges will depend in part upon physician
and surgeon recommendations as well as other factors, including the
effectiveness, safety, reliability and invasiveness of the procedure as
compared to established approaches. Even if the Company's soundbridges are
adopted by the medical community, a significant market may not develop for the
Company's products unless acceptable reimbursement from health care payors is
available. There can be no assurance that the Company's soundbridges under
development will be accepted by the medical community or consumers or that
market demand for such products will be sufficient to allow the Company to
achieve profitable operations. Failure of the Company's soundbridges, for
whatever reason, to achieve significant adoption by the medical community or
consumers or failure of the Company's products to achieve any significant
market acceptance would have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business--
Government Regulation" and "--Third-Party Reimbursement."
       
HIGHLY COMPETITIVE MARKET; RISK OF COMPETING HEARING DEVICES
 
  The medical device industry is subject to intense competition in the United
States and abroad. The Company believes its products will compete primarily
with the traditional approaches to managing hearing impairment, principally
hearing aids. Principal manufacturers of acoustic hearing aids include Siemens
Hearing Instruments, Inc., Philips Medical Systems North America Co., Starkey
Laboratories Inc., Beltone Electronics Corp., Dahlberg Inc., ReSound Corp.,
Oticon, Inc., Widex Hearing Aid Co., Inc. and Phonak Inc. There can be no
assurance that the Company's soundbridges will be able to successfully compete
with established hearing aid products. In addition, there can be no assurance
that these potential competitors will not succeed in developing technologies
and products in the future that are more effective, less expensive than those
being developed by the Company or that do not require surgery. The Company is
aware of several university research groups and development-stage companies
that have active research or development programs related to direct drive
sensorineural hearing devices. In addition, some large medical device
companies, some of which are currently marketing implantable medical devices,
may develop programs in hearing management. Certain of these companies have
substantially greater financial, technical, manufacturing, marketing and other
resources than the Company. In addition, there can be no assurance that
certain of the Company's competitors will not develop technologies and
products that may be more effective in managing hearing impairment than the
Company's products or that render the Company's products obsolete. See
"Business--Competition."
 
LIMITED MANUFACTURING EXPERIENCE; SCALE-UP RISK; DEPENDENCE ON KEY SUPPLIERS
   
  The Company currently manufactures its products in limited quantities for
laboratory testing and for its United States and European clinical trials. The
manufacture of the Vibrant soundbridge is a complex operation involving a
number of separate processes, components and assemblies. Each device is
assembled and individually tested by the Company. The manufacturing process
consists primarily of assembly of internally manufactured and purchased
components and subassemblies, and certain processes are performed in an
environmentally controlled area. After completion of the manufacturing and
testing processes, implantable devices are sterilized by a sub-contracted
supplier. The Company has no experience manufacturing its products in the
volumes or with the yields that     
 
                                       9
<PAGE>
 
   
will be necessary for the Company to achieve significant commercial sales, and
there can be no assurance that the Company can establish high-volume
manufacturing capacity or, if established, that the Company will be able to
manufacture its products in high volumes with commercially acceptable yields.
If the Company receives regulatory approval to commercialize its products, it
will need to expend significant capital resources and develop manufacturing
expertise to establish large-scale manufacturing capabilities. The Company
intends to expand its manufacturing capacity into a new facility in the first
quarter of 1998, before it commences large-scale commercial manufacturing
activities. Furthermore, prior to approval of a PMA, the Company's facilities,
procedures and practices will be subject to a pre-approval inspection by the
FDA. The Company's inability to successfully manufacture its products in a
timely manner or at a reasonable cost could have a material adverse effect on
the Company's business, financial condition and results of operations.     
   
  Raw materials, components and subassemblies for the Company's soundbridges
are purchased from various qualified suppliers. A number of components and
subassemblies, such as silicone, control electronics and implant packaging are
provided by single source suppliers. One component, the signal processing
microcircuit, is provided by a sole source supplier, Gennum Corporation. None
of the Company's vendors is contractually obligated to continue to supply the
Company nor is the Company contractually obligated to buy from a particular
vendor. For certain of these components and subassemblies, there are
relatively few alternative sources of supply, and establishing additional or
replacement suppliers for such components and subassemblies could not be
accomplished quickly. In addition, if the Company wishes to significantly
modify its manufacturing processes or change the supplier of a critical
component, additional approvals will be required from the FDA before the
change can be implemented. Because of the long lead time for some components
and subassemblies that are currently available from a single source, a
supplier's inability or failure to supply such components or subassemblies in
a timely manner or the Company's decision to change its suppliers could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business--Manufacturing."     
 
DEPENDENCE UPON PATENTS AND PROPRIETARY TECHNOLOGY
   
  In the United States, the Company holds three issued patents and 11 pending
patent applications. Additionally, the Company has ten pending foreign patent
applications. These patents and patent applications generally cover the
invention and application of the FMT as well as the specific application of
the FMT and other concepts in the field of hearing impairment. In addition,
the Company has licensed, on a royalty-free basis, a United States patent
covering the magnetic attachment of an external audio processor to an
implanted receiver. The Company's success will depend in part on its ability
to obtain patent protection for its products and processes, to preserve its
trade secrets and to operate without infringing or violating the proprietary
rights of others.     
 
  The patent positions and trade secret provisions of medical device
companies, including those of the Company, are uncertain and involve complex
and evolving legal and factual questions. The coverage sought in a patent
application either can be denied or significantly reduced before or after the
patent is issued. Consequently, there can be no assurance that any patents
from pending applications or from any future patent application will be
issued, that the scope of the patent protection will exclude competitors or
provide competitive advantages to the Company, that any of the Company's
patents will be held valid if subsequently challenged or that others will not
claim rights in or ownership of the patents and other proprietary rights held
by the Company. Since patent applications are secret until patents are issued
in the United States or corresponding applications are published in other
countries, and since publication of discoveries in the scientific or patent
literature often lags behind actual discoveries, the Company cannot be certain
that it was the first to file patent applications for such inventions.
 
  In addition, there can be no assurance that competitors, many of which have
substantial resources, will not seek to apply for and obtain patents that will
prevent, limit or interfere with the
 
                                      10
<PAGE>
 
Company's ability to make, use or sell its products either in the United
States or in international markets. Although the Company has conducted
searches of patents issued to other companies, research or academic
institutions or others, there can be no assurance that such patents do not
exist, have not been filed or could not be filed or issued, which contain
claims relating to the Company's technology, products or processes. Patents
issued and patent applications filed in the United States or internationally
relating to medical devices are numerous and there can be no assurance that
current and potential competitors and other third parties have not filed or in
the future will not file applications for, or have not received or in the
future will not receive, patents or obtain additional proprietary rights
relating to products or processes used or proposed to be used by the Company.
In addition, patent applications in foreign countries are maintained in
secrecy for a period after filing. Publication of discoveries in the
scientific or patent literature tends to lag behind actual discoveries and the
filing of related patent applications. There may be pending applications,
which if issued with claims in their present form, might provide proprietary
rights to third parties relating to products or processes used or proposed to
be used by the Company. The Company may be required to obtain licenses to
patents or proprietary rights of others. Further, the laws of certain foreign
countries do not protect the Company's intellectual property rights to the
same extent as do the laws of the United States. Litigation or regulatory
proceedings, which could result in substantial cost and uncertainty to the
Company, may also be necessary to enforce patent or other intellectual
property rights of the Company or to determine the scope and validity of other
parties' proprietary rights. There can be no assurance that the Company will
have the financial resources to defend its patents from infringement or claims
of invalidity.
 
  The Company also relies upon trade secrets and other unpatented proprietary
technology, and no assurance can be given that others will not independently
develop substantially equivalent proprietary information and techniques or
otherwise gain access to or disclose the Company's proprietary technology or
that the Company can meaningfully protect its rights in such unpatented
proprietary technology. The Company's policy is to require each of its
employees, consultants, investigators and advisors to execute a
confidentiality agreement upon the commencement of an employment or consulting
relationship with the Company. These agreements generally provide that all
inventions conceived by the individual during the term of the relationship
shall be the exclusive property of the Company and shall be kept confidential
and not be disclosed to third parties except in specified circumstances. There
can be no assurance, however, that these agreements will provide meaningful
protection for the Company's proprietary information in the event of
unauthorized use or disclosure of such information.
 
  Recently Public Law 104-208 was signed into law in the United States and
limits the enforcement of patents relating to the performance of surgical or
medical procedures on a body. This law precludes medical practitioners and
health care entities who practice these procedures from being sued for patent
infringement. Therefore, depending upon how these limitations are interpreted
by the courts, they could have a material adverse effect on the Company's
ability to enforce any of its proprietary methods or procedures deemed to be
surgical or medical procedures. In certain other countries outside the United
States, patent coverage relating to the performance of surgical or medical
procedures is not available. Therefore, patent coverage in such countries will
be limited to the FMT or to narrower aspects of the FMT.
 
  The medical device industry in general has been characterized by substantial
litigation. Litigation regarding patent and other intellectual property
rights, whether with or without merit, could be time-consuming and expensive
to respond to and could distract the Company's technical and management
personnel. The Company may become involved in litigation to defend against
claims of infringement by the Company, to enforce patents issued to the
Company or to protect trade secrets of the Company. If any relevant claims of
third-party patents are held as infringed and not invalid in any litigation or
administrative proceeding, the Company could be prevented from practicing the
subject
 
                                      11
<PAGE>
 
matter claimed in such patents, or would be required to obtain licenses from
the patent owners of each such patent, or to redesign its products or
processes to avoid infringement. In addition, in the event of any possible
infringement, there can be no assurance that the Company would be successful
in any attempt to redesign its products or processes to avoid such
infringement or in obtaining licenses on terms acceptable to the Company, if
at all. Accordingly, an adverse determination in a judicial or administrative
proceeding or failure by the Company to redesign its products or processes or
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. Although
the Company has not been involved in any litigation to date, in the future,
costly and time-consuming litigation brought by the Company may be necessary
to enforce patents issued to 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. See "Business--Patents and Proprietary
Technology."
 
FUTURE CAPITAL REQUIREMENTS; UNCERTAINTY OF ADDITIONAL FUNDING
   
  The Company will expend substantial funds in the future for research and
development, preclinical and clinical testing, capital expenditures and the
manufacturing, marketing and sale of its products. The timing and amount of
spending of such capital resources cannot be accurately predicted and will
depend upon several factors, including the progress of its research and
development efforts and preclinical and clinical activities, competing
technological and market developments, the time and costs of obtaining
regulatory approvals, the time and costs involved in filing, prosecuting and
enforcing patent claims, the progress and cost of commercialization of
products currently under development, market acceptance and demand for the
Company's products if approved for marketing and other factors not within the
Company's control. While the Company believes that the net proceeds of this
offering, together with its existing capital resources and projected interest
income, will be sufficient to fund its operations and its capital investments
for at least the next 18 months, there can be no assurance that the Company
will not require additional financing prior to that time. There can be no
assurance that such additional financing will be available on a timely basis
on terms acceptable to the Company, or at all, or that such financing will not
be dilutive to stockholders. If adequate funds are not available, the Company
could be required to delay development or commercialization of certain of its
products, to license to third parties the rights to commercialize certain
products or technologies that the Company would otherwise seek to
commercialize for itself, or to reduce the marketing, customer support or
other resources devoted to certain of its products, any of which could have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Use of Proceeds," "Dilution" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources."     
 
LACK OF SALES, MARKETING AND DISTRIBUTION EXPERIENCE
   
  The Company will have to establish an effective internal sales and marketing
organization prior to commercial introduction of its products. The Company is
in the process of establishing a sales and marketing organization in Europe.
An office has been established in Basel, Switzerland, where the Company's
Director of European Sales and Marketing and European Clinical Manager are
based. The Company has recruited sales personnel to provide direct sales
coverage in Germany, France and the United Kingdom, who will commence their
employment during the first quarter of 1998. In other international markets,
including Japan, the Company will seek to establish a network of distributors.
By the end of the first quarter of 1998, the Company intends to establish
distributors in Italy, Spain and the Benelux countries. There can be no
assurance that the Company will be able to build a direct sales force or
marketing organization in any country, that establishing a direct sales force
or marketing organization will be cost-effective or that the Company's sales
and marketing efforts will be successful. In addition, the Company has had
discussions with only a limited number of potential     
 
                                      12
<PAGE>
 
international distributors and has not yet entered into any agreements with
distributors. There can be no assurance that the Company will be able to enter
into agreements with qualified distributors on a timely basis on terms
acceptable to the Company, or at all, or that such distributors will devote
adequate resources to selling the Company's products. Failure to establish a
direct sales force domestically and in select international markets, and to
enter into successful distribution relationships, could have a material
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Sales, Marketing and Training."
 
UNCERTAIN AVAILABILITY OF THIRD-PARTY REIMBURSEMENT
 
  The Company believes that its products will generally be purchased by
hospitals and clinics upon the recommendation of a surgeon. In the United
States, hospitals, physicians and other health care providers that purchase
medical devices generally rely on third-party payors, to reimburse all or part
of the cost of the procedure in which the medical device is being used. Such
third-party payors have become increasingly sensitive to cost containment in
recent years and place a high degree of scrutiny on coverage and payment
decisions for new technologies and procedures.
 
  Hearing aids, which are the subject of 510(k) clearance and do not involve
surgery, are generally not reimbursed, although a modest reimbursement is
provided under certain insurance plans. Traditionally, hearing aid users have
paid for these devices directly. There can be no assurance that the Company
will be able to demonstrate improvement in quality of life or that
reimbursement will ever be available for the Company's products. During
clinical trials, the Company does not anticipate that there will be any
reimbursement for the Vibrant soundbridge implant or procedure.
 
  Certain third-party payors are moving toward a managed care system in which
they contract to provide comprehensive health care for a fixed cost per
person. The fixed cost per person established by these third-party payors may
be independent of the hospital's cost incurred for the specific case and the
specific devices used. Medicare and other third-party payors are increasingly
scrutinizing whether to cover new products and the level of reimbursement for
covered products. Because the Company's products are currently under
development and have not received FDA clearance or approval, uncertainty
exists regarding the availability of third-party reimbursement for procedures
that would use the Company's soundbridges. Failure by physicians, hospitals
and other potential users of the Company's soundbridges to obtain sufficient
reimbursement from third-party payors for the procedures in which the
Company's soundbridges are intended to be used could have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
  Third-party payors that do not use prospectively fixed payments increasingly
use other cost-containment processes or require various outcomes data that may
pose administrative hurdles to the use of the Company's soundbridges. In
addition, third-party payors may deny reimbursement if they determine that the
device used in a procedure is unnecessary, inappropriate, experimental, used
for a non-approved indication or is not cost-effective. Potential purchasers
must determine that the clinical benefits of the Company's products justify
the additional cost or the additional effort required to obtain prior
authorization or coverage and the uncertainty of actually obtaining such
authorization or coverage.
 
  If the Company obtains the necessary foreign regulatory approvals, market
acceptance of the Company's products and products currently under development
in international markets would be dependent, in part, upon the availability of
reimbursement within prevailing health care payment systems. Reimbursement and
health care payment systems in international markets vary significantly by
country and include both government sponsored health care and private
insurance. There can be no assurance that any international reimbursement
approvals will be obtained in a timely manner, if at all. Failure to receive
international reimbursement approvals could have a material adverse effect on
market acceptance of the Company's products in the international markets in
which such approvals are sought. See "Business--Third-Party Reimbursement."
 
                                      13

DEPENDENCE UPON KEY PERSONNEL
   
  The Company's future success depends in significant part upon the continued
service of certain key scientific, technical and management personnel.
Competition for such personnel is intense and there can be no assurance that
the Company can retain its key scientific, technical and managerial personnel
or that it can attract, assimilate or retain other highly qualified
scientific, technical and managerial personnel in the future. The loss of key
personnel, especially if without advance notice, or the inability to hire or
retain qualified personnel could have a material adverse effect upon the
Company's business, financial condition and results of operations. The Company
has not entered into employment agreements with any of its key personnel. The
Company is the beneficiary under a $1.0 million key man insurance policy on
Harry S. Robbins, its President and Chief Executive Officer.     
 
PRODUCT LIABILITY RISK; POSSIBLE INSUFFICIENCY OF INSURANCE
 
  The manufacture, sale and implantation of the Company's products involve the
risk of product liability claims. The Company currently has limited product
liability insurance. There can be no assurance that such insurance will be
available on commercially reasonable terms or that the coverage limits will be
adequate. The Company intends to evaluate its coverage on a regular basis and
in connection with the introduction of products currently under development.
Such insurance is expensive and may not be available on acceptable terms, in
sufficient amount of coverage or at all. A successful claim brought against
the Company in excess of its insurance coverage would have a material adverse
effect on the Company's business, financial condition and results of
operations. See "Business--Product Liability."
 
CONTROL BY EXISTING STOCKHOLDERS
   
  After the completion of this offering, current stockholders, including
certain executive officers and directors of the Company and their affiliates,
will own approximately 81.4% of the outstanding Common Stock (assuming the
exercise of all outstanding options and warrants). As a result, these
stockholders will, to the extent they act together, continue to have the
ability to exert significant influence and control over matters requiring the
approval of the Company's stockholders, including the election of a majority
of the Company's Board of Directors. See "Principal Stockholders."     
 
POTENTIAL ADVERSE IMPACT OF SHARES ELIGIBLE FOR FUTURE SALE
   
  Sales of Common Stock (including shares issued upon the exercise of
outstanding options) in the public market after this offering could materially
and adversely affect the market price of the Common Stock. Such sales also
might make it more difficult for the Company to sell equity securities or
equity-related securities in the future at a time and price that the Company
deems appropriate. Upon the completion of this offering, the Company will have
11,766,742 shares of Common Stock outstanding (assuming no exercise of options
after December 31, 1997), of which the 2,300,000 shares offered hereby will be
freely tradeable (unless held by affiliates of the Company) without
restriction. The remaining 9,466,742 shares will be restricted securities
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act"). The Company and its directors, executive officers and all other holders
of such restricted securities, have entered into lock-up agreements with the
Company or Cowen & Company (the "Lock-up Agreements") under which they have
agreed not to offer, sell, contract to sell, grant any options to purchase or
otherwise dispose of, directly or indirectly, any shares of Common Stock or
options to acquire shares of Common Stock, or securities exchangeable or
convertible into shares of Common Stock, owned by them for a period of 180
days following the day on which the Registration Statement becomes effective
without the prior written consent of Cowen & Company or the Company, as the
case may be except that, without such consent, the Company may issue Common
Stock and grant options pursuant to the 1994 Option Plan and issue Common
Stock pursuant to the exercise of outstanding warrants and the current
stockholders     
 
                                      14
<PAGE>
 
   
of the Company who are not executive officers or directors of the Company may
sell Common Stock acquired in the offering or in the open market. The Company
has agreed not to release any stockholders from the terms of the Lock-up
Agreements with the Company. Cowen & Company may, in its sole discretion and
at any time without notice, release all or any portion of the shares subject
to such Lock-up Agreements. As a result of the Lock-up Agreements and the
provisions of Rules 144 and 701 promulgated under the Securities Act, upon
consummation of this offering, such restricted securities will be available
for public resale in the public market as follows: (i) no shares will be
available for immediate sale on the date of this Prospectus and (ii)
approximately 9,778,368 shares will be available for public resale 180 days
after the date of this Prospectus, upon expiration of the Lock-up Agreements
(including approximately 311,615 shares subject to outstanding vested options
and outstanding warrants), subject in some cases to volume limitations
pursuant to Rule 144. In addition, 6,715,689 of the shares outstanding
immediately following the completion of this offering (including up to 33,611
shares of Common Stock issuable upon exercise of certain outstanding warrants)
will be entitled to registration rights with respect to such shares upon
termination of the Lock-up Agreements. The number of shares sold in the public
market could increase if such registration rights are exercised and such sales
may have an adverse effect on the market price of the Common Stock. See
"Shares Eligible for Future Sale."     
 
NO PRIOR PUBLIC MARKET; POSSIBLE VOLATILITY OF STOCK
 
  Prior to this offering, there has been no public market for the Common
Stock. There can be no assurance that an active trading market will develop or
be sustained or that the market price of the Common Stock will not decline
below the initial public offering price. The initial public offering price of
the Common Stock is determined by negotiations between the Company and the
Underwriters. As such, the initial public offering price is not necessarily
related to the Company's net worth or any other established criteria of value
and may not bear any relationship to the market price of the Common Stock
following the completion of the offering. The market prices for securities of
medical device companies have historically been highly volatile. Announcements
of technological innovations or new products by the Company or its
competitors, developments concerning proprietary rights, including patents and
litigation matters, publicity regarding actual or potential results with
respect to products under development by the Company or others, regulatory
developments in both the United States and foreign countries and public
concern as to the safety of new technologies, changes in financial estimates
by securities analysts or failure of the Company to meet such estimates and
other factors may have a significant impact on the market price of the Common
Stock. In addition, the Company believes that fluctuations in its operating
results may cause the market price of its Common Stock to fluctuate, perhaps
substantially. See "Underwriting."
 
DILUTION; ABSENCE OF DIVIDENDS
   
  Purchasers of shares of Common Stock offered hereby will experience an
immediate dilution of $9.17 in the pro forma net tangible book value per share
of their Common Stock from the assumed initial public offering price of $12.00
per share. The Company has never paid dividends on its Common Stock and does
not anticipate paying any cash dividends in the foreseeable future. See
"Dividend Policy" and "Dilution."     
 
ANTI-TAKEOVER EFFECT OF DELAWARE LAW AND CERTAIN CHARTER, BYLAWS AND
CONTRACTUAL PROVISIONS
 
  Certain provisions of the Company's Restated Certificate of Incorporation
and Bylaws may have the effect of making it more difficult for a third party
to acquire, or discouraging a third party from attempting to acquire, control
of the Company. Such provisions could limit the price that certain investors
might be willing to pay in the future for shares of the Company's Common
Stock. Certain of these provisions eliminate the right of stockholders to act
by written consent without a meeting and specify procedures for director
nominations by stockholders and submission of other proposals
 
                                      15
<PAGE>
 
for consideration at stockholder meetings. In addition, the Company's Board of
Directors has the authority to issue up to 5,000,000 shares of Preferred Stock
and to determine the price, rights, preferences, privileges and restrictions
of those shares without any further vote or action by the stockholders. The
rights of the holders of Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any Preferred Stock that may be
issued in the future. The issuance of Preferred Stock could have the effect of
making it more difficult for a third party to acquire a majority of the
outstanding voting stock of the Company. The Company has no present plans to
issue shares of Preferred Stock. Certain provisions of Delaware law applicable
to the Company could also delay or make more difficult a merger, tender offer
or proxy contest involving the Company, including Section 203 of the Delaware
General Corporation Law, which prohibits a Delaware corporation from engaging
in any business combination with any interested stockholder for a period of
three years unless certain conditions are met. The existence of a classified
Board of Directors, the inability of stockholders to act by written consent
without a meeting, the procedures required for director nominations and
stockholder proposals and Delaware law could have the effect of delaying,
deferring or preventing a change in control of the Company, including without
limitation, discouraging a proxy contest or making more difficult the
acquisition of a substantial block of the Company's Common Stock. These
provisions could also limit the price that investors might be willing to pay
in the future for shares of the Company's Common Stock. In addition, the
Company has granted one of its existing stockholders, Johnson & Johnson
Development Corporation ("JJDC"), first negotiation rights with regard to
certain proposed transactions, which may have the effect of making it more
difficult for a third party to acquire, or discouraging a third party from
attempting to acquire, control of the Company. See "Certain Transactions" and
"Description of Capital Stock."

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
 
  Certain statements contained in this Prospectus, including without
limitation, statements containing the words "believes," "anticipates,"
"expects" and words of similar import, constitute "forward-looking
statements." Such forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause the actual results,
performance or achievements of Symphonix to be materially different from any
future results, performance or achievements expressed or implied by such
forward-looking statements. Such factors include the following: uncertainties
related to the early stage of the Company's development; limited clinical
testing experience; uncertainties related to the reliance on the Company's FMT
technology; existing government regulations and changes in, or the failure to
comply with, government regulations; the Company's limited manufacturing
experience, the risk associated with manufacturing scale-up, and the Company's
dependence on key suppliers; uncertainty of market acceptance; history of
operating losses and expectations of future losses; the highly competitive
market and the risk of competing hearing management approaches; dependence on
patents and proprietary technology and uncertainty of patent protection;
future capital needs and uncertainty of additional funding; dependence on key
personnel; the Company's lack of sales, marketing and distribution experience
and reliance on third parties to perform such functions; uncertain
availability of third-party reimbursement and other factors referenced in this
Prospectus. Certain of these factors are discussed in more detail elsewhere in
this Prospectus, including, without limitation, under the captions "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business." Given these
uncertainties, prospective investors are cautioned not to place undue reliance
on such forward-looking statements. Symphonix disclaims any obligation to
update any such factors or to publicly announce the result of any revisions to
any of the forward-looking statements contained herein to reflect future
events or developments.

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of 2,300,000 shares of Common
Stock offered hereby are estimated to be approximately $24,868,000
($28,718,200 if the Underwriters' over-allotment option is exercised in full),
at an assumed initial public offering price of $12.00 per share and after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by the Company.
   
  The Company anticipates that it will use approximately $10.0 million of the
net proceeds of this offering to fund the Company's research and development
efforts, including clinical trials, approximately $3.0 million to develop a
sales and marketing organization and initiate commercial sales of its
products, when and if approved for marketing by regulatory authorities, and
approximately $1.0 million for making leasehold improvements and other capital
expenditures. The Company will use the remaining net proceeds for working
capital and general corporate purposes. Although the Company believes the
proceeds of this offering, together with its existing resources and projected
interest income will be adequate to fund its operations and its capital
investments for at least the next 18 months, the timing and amount of spending
of such capital resources cannot be accurately determined at this time and
will depend upon several factors, including the timing and cost of obtaining
regulatory approvals, progress of its research and development efforts and
preclinical and clinical activities, competing technological and market
developments, commercialization of products currently under development, and
market acceptance and demand for the Company's products if approved for
marketing. The Company's management will retain broad discretion in the
allocation of a substantial portion of the net proceeds. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Liquidity and Capital Resources" and "Business--Facilities."     
 
  Pending such uses, the Company intends to invest the net proceeds in short-
term, interest-bearing, investment grade securities.
 
                                DIVIDEND POLICY
   
  The Company has not declared or paid any cash dividends on its capital
stock. The Company currently expects to retain its future earnings for use in
the operation and expansion of its business and does not anticipate paying any
cash dividends in the foreseeable future. Additionally, under the Company's
line of credit agreement, the Company is prohibited from paying cash dividends
without the bank's prior approval.

restatement of the Company's Certificate of Incorporation to provide for
authorized capital stock consisting of 50,000,000 shares of Common Stock and
5,000,000 shares of undesignated Preferred Stock, and (iii) as adjusted to
reflect the application of the estimated net proceeds from the sale of

                                   DILUTION
   
  The pro forma net tangible book value of the Company as of December 31, 1997
was $8.5 million or $0.89 per share of Common Stock. Pro forma net tangible
book value per share represents the Company's total tangible assets less total
liabilities, divided by the pro forma number of outstanding shares of Common
Stock (after giving effect to the conversion of the Preferred Stock into
Common Stock). Dilution per share represents the difference between the amount
per share paid by investors in this offering and the pro forma net tangible
book value per share after the offering. After giving effect to the sale of
2,300,000 shares in this offering at an assumed initial public offering price
of $12.00 per share and after deducting the estimated underwriting discounts
and commissions and estimated offering expenses, the pro forma net tangible
book value of the Company as of December 31, 1997 would have been $33.3
million or $2.83 per share. This represents an immediate increase of pro forma
net tangible book value of $1.94 per share to existing stockholders and an
immediate dilution in pro forma net tangible book value of $9.17 per share to
new investors purchasing shares of Common Stock in this offering, as
illustrated in the following table:

                     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 contains forward-looking statements that involve
risks and uncertainties. The Company's actual results could differ materially
from those anticipated in these forward-looking statements as a result of
certain factors, including those set forth under "Risk Factors" and elsewhere
in this Prospectus.
 
OVERVIEW
   
  Since its inception in May 1994, Symphonix has been a development stage
company. The Company is developing a family of proprietary semi-implantable
and implantable soundbridges for the management of moderate to severe hearing
impairment. The Company's family of Vibrant soundbridges are based on its
patented core FMT technology. The Company has not generated any revenue from
sales of products and as of December 31, 1997, had an accumulated deficit of
$18.4 million. To date, the Company's principal sources of funding have been
private equity financings, equipment leases and bank borrowings.     
   
  In September 1996, the Company initiated clinical trials of the Vibrant
soundbridge in both the United States and Europe, and in July 1997, the
Company initiated clinical trials of the Vibrant P soundbridge in Europe. The
Company will be required to conduct further research, development, testing and
regulatory activities. The costs of these activities, together with the costs
of establishing commercial-scale manufacturing and sales and marketing
capabilities, and general and administrative expenses, are expected to result
in substantial losses through at least 1999.     
 
RESULTS OF OPERATIONS
   
  Research and Development Expenses. Research and development expenses were
$707,000 in the period ended December 31, 1994, and $3.3 million, $5.4 million
and $6.4 million in the years ended December 31, 1995, 1996 and 1997,
respectively. Research and development expenses consist primarily of personnel
costs, professional services, materials, supplies and equipment in support of
product development, clinical trials, regulatory submissions and patent
applications. Expenses increased from the period ended December 31, 1994 to
the year ended December 31, 1995, due to the inclusion of a full year of
expenses in 1995, and to increases in the level of staffing, professional
services, and other costs as the Company established a research and
development organization and initiated its product development effort.
Expenses increased from 1995 to 1996 and from 1996 to 1997, due to increases
in the level of staffing and increased spending on supplies, professional
services and equipment as the Company increased its product development
efforts, developed its clinical research and regulatory functions, initiated
clinical trials of its products and established a pilot manufacturing
capability.     
   
  General and Administrative Expenses. General and administrative expenses
were $141,000 in the period ended December 31, 1994, and $625,000, $1.0
million and $2.0 million in the years ended December 31, 1995, 1996 and 1997,
respectively. General and administrative expenses consist primarily of
personnel costs and professional services. Expenses increased from the period
ended December 31, 1994 to the year ended December 31, 1995, due to the
inclusion of a full year of expenses in 1995, and to increases in the level of
staffing as the Company increased its product development activities. Expenses
increased from 1995 to 1996 and from 1996 to 1997, due to further increases in
the level of staffing and spending on professional services.     
 
                                      22

  Deferred compensation of $1.6 million was recorded in 1997, representing the
difference between the exercise prices of certain options granted and the
deemed fair value of the Company's Common Stock on the grant dates. Deferred
compensation expense of $107,000 attributed to such options was amortized
during the year ended December 31, 1997. The remaining deferred compensation
will be amortized over the vesting period of the options (generally four
years).     
   
  Interest Income, Net. Interest income, net was $96,000 in the period ended
December 31, 1994, and $280,000, $337,000 and $475,000 in the years ended
December 31, 1995, 1996 and 1997, respectively. The increases in interest
income over these periods were primarily due to the Company's increasing
average cash and short-term investment balances, which have been the result of
the timing of the Company's private equity financings.     
   
  Income Taxes. As a result of the net losses incurred, the Company has not
incurred any income tax obligations. At December 31, 1997, the Company had net
operating loss carryforwards of $13.2 million for federal and $13.1 million for
state income tax purposes, which will expire at various dates through 2012 if
not utilized. The principal differences between losses for financial and tax
reporting purposes are the result of the capitalization of research and
development and start-up expenses for tax purposes. United States and state tax
laws contain provisions that may limit the net operating loss carryforwards
that can be used in any given year, should certain changes in the beneficial
ownership of the Company's shares occur. Such events could limit the future
utilization of the Company's net operating loss carryforwards.     
 
LIQUIDITY AND CAPITAL RESOURCES
   
  Since inception, the Company has funded its operations and its capital
investments from the private sale of equity securities, totaling $26.7 million,
from equipment lease financing totaling $1.3 million and from bank borrowings
totaling $2.0 million. At December 31, 1997, the Company had $9.6 million in
working capital, and its primary source of liquidity was $11.5 million in cash,
cash equivalents and short-term investments.     
   
  Capital expenditures, primarily related to the Company's research and
development and manufacturing activities, were $294,000 in the period ended
December 31, 1994, and $691,000, $409,000 and $898,000 in the years ended
December 31, 1995, 1996 and 1997, respectively. At December 31, 1997, the
Company did not have any material commitments for capital expenditures, except
as set forth below.     
   
  In October 1997, the Company entered into a five-year lease commencing in
January 1998 for a new facility (see Note 7 of Notes to Consolidated Financial
Statements). The Company anticipates that it will incur capital expenditures of
approximately $1.0 million for leasehold improvements with respect to this
facility. Through December 31, 1997, approximately $350,000 has been incurred
and the balance is expected to be incurred in the first quarter of 1998.     
   
  The Company has a loan agreement with a bank providing for borrowings of up
to $2.0 million and for the issuance of letters of credit up to $250,000. At
December 31, 1997 the Company had borrowings of $2.0 million and an outstanding
letter of credit in the amount of $243,680 under the loan agreement (see Note 6
of Notes to Consolidated Financial Statements).     
   
  Cash used in operating activities was $519,000 in the period ended December
31, 1994 and $3.1 million, $5.4 million and $6.5 million in the years ended
December 31, 1995, 1996 and 1997, respectively. The increases in cash used in
operating activities over these periods reflect the increased net losses
incurred, primarily as a result of higher research and development expenses.
    
  The Company will expend substantial funds in the future for research and
development, preclinical and clinical testing, capital expenditures and the
manufacturing, marketing and sale of its products. The timing and amount of
spending of such capital resources cannot be accurately
 
                                       23
<PAGE>
 
   
predicted and will depend upon several factors, including the progress of its
research and development efforts and preclinical and clinical activities,
competing technological and market developments, the time and costs of
obtaining regulatory approvals, the time and costs involved in filing,
prosecuting and enforcing patent claims, the progress and cost of
commercialization of products currently under development, market acceptance
and demand for the Company's products if approved for marketing and other
factors not within the Company's control. While the Company believes that the
net proceeds of this offering, together with its existing capital resources
and projected interest income, will be sufficient to fund its operations and
its capital investments for at least the next 18 months, there can be no
assurance that the Company will not require additional financing prior to that
time. There can be no assurance that such additional financing will be
available on a timely basis on terms acceptable to the Company, or at all, or
that such financing will not be dilutive to stockholders. If adequate funds
are not available, the Company could be required to delay development or
commercialization of certain of its products, to license to third parties the
rights to commercialize certain products or technologies that the Company
would otherwise seek to commercialize for itself, or to reduce the marketing,
customer support or other resources devoted to certain of its products, any of
which could have a material adverse effect on the Company's business,
financial condition and results of operations.

                                   BUSINESS
 
  The following Business section contains forward-looking statements which
involve risks and uncertainties. The Company's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including those set forth under "Risk Factors," and
elsewhere in this Prospectus.
 
OVERVIEW
   
  Symphonix is a leader in the development of proprietary semi-implantable and
implantable products, or soundbridges, for the management of moderate to
severe hearing impairment. In 1994, mild to severe hearing impairment affected
approximately 26 million people in the United States, or 10% of the
population, of whom approximately 17 million people were classified as
moderately or severely hearing impaired. The Company believes that its family
of Vibrant soundbridges, designed to overcome the inherent limitations of
traditional hearing devices, represent a novel approach in the management of
hearing impairment. The Company's initial product under development, the
Vibrant soundbridge, is a semi-implantable device which mechanically drives
the three small bones of the middle ear to overcome the user's hearing
impairment. The Company's second generation product, the Vibrant P
soundbridge, provides a greater degree of customization to address the
specific needs of a particular user's hearing loss and expands the types of
hearing loss that can be managed by the Company's products. In September 1996,
the Company initiated clinical trials of the Vibrant soundbridge in both the
United States and Europe, and in July 1997 the Company initiated clinical
trials of the Vibrant P soundbridge in Europe. As of January 5, 1998, 48
patients have been implanted with the Company's soundbridges, of whom 44 have
had the Audio Processor fitted and the soundbridge's performance evaluated.
    
THE HEARING IMPAIRMENT MARKET
 
 Background
 
  The human ear consists of three regions: the outer ear, the middle ear and
the inner ear. The outer ear consists of the external auricle and the ear
canal. The ear canal is a passageway through which sound waves reach the
middle ear. The outer ear is separated from the middle ear by the tympanic
membrane, commonly referred to as the eardrum. The middle ear is a chamber
that contains three tiny bones, the malleus, the incus, and the stapes, that
together are known as the ossicles. The ossicles form a chain from the
tympanic membrane to the inner ear. The inner ear includes the cochlea, which
is a fluid-filled structure that contains a large number of delicate sensory
hair cells that are connected to the auditory nerve.
 
  Sound, which is a wave-like vibration of the air, enters the ear canal and
is slightly amplified by the natural resonant characteristics of the ear
canal. These sound waves cause vibration of the tympanic membrane and are
amplified and transmitted to the fluid filling the inner ear by the motion of
the ossicles. The waves created in the fluid pass through the snail-shaped
cochlea and stimulate the delicate sensory hair cells. These hair cells
generate electrochemical signals that are detected by the auditory nerve and
are then subsequently interpreted by the brain as sound.
 
  The signals that are interpreted by the brain as sound are distinguished by
frequency and intensity. The frequency of sound is perceived as pitch and is
measured in cycles per second, or Hertz ("Hz"). The normal human ear perceives
sounds in the range of 20 to 18,000 Hz, although most components of human
speech are generally in the range of 400 to 4,000 Hz. A more subtle aspect of
frequency is that certain letters of the alphabet are spoken at a different
frequency than others. For example, certain consonants such as "m," "n" and
"g" and all vowels are spoken at relatively low frequencies while other
consonants and sounds such as "t," "s," "f" and "sch" are spoken at higher
frequencies. Accordingly, at a given volume, certain letters may be more
audible than others.
 
                                      25
<PAGE>
 
  The intensity of sound is perceived as loudness and is measured in decibels
("dB"). The lowest level of intensity at which an individual perceives sound
is known as the threshold of hearing. The range in decibels from a person's
threshold of hearing to the level at which the person perceives sound to be
uncomfortably loud is known as the dynamic range. Both the threshold of
hearing and the dynamic range vary with the frequency of sound. An individual
with normal hearing can comfortably hear sounds ranging in intensity from
approximately 30 dB to 100 dB.

 Hearing Impairment
 
  Hearing impairment can adversely effect a person's quality of life and
psychological well-being. Hearing impaired people often withdraw from
discussions and other social interactions to avoid frustration and
embarrassment from not being able to fully participate in and understand
conversations. Difficulty in communicating effectively can lead to negative
emotions and attitudes, increased stress levels, reduced self-confidence,
reduced sociability and reduced effectiveness in the workplace. In addition,
recent studies suggest that hearing impairment may also contribute to
physiological complications, such as heart disease.
 
  Audiologists typically classify the hearing impaired population into four
categories: mild, moderate, severe and profound. In 1994, the total hearing
impaired population in the United States was approximately 26 million people,
of whom approximately 17 million were classified as either moderately or
severely hearing impaired.
 
  While the exact causes of hearing impairment are varied and unclear, hearing
impairment can be characterized according to its physiological source. There
are two general categories of hearing impairment, conductive and
sensorineural, although sometimes a combination of the two may arise.
Conductive hearing impairment results from diseases or disorders that limit
the transmission of sound through the outer and/or middle ear. Conductive
hearing impairment is often treated surgically with an implanted prosthesis to
replace part or all of the ossicles. The Company believes that people with a
conductive hearing loss represent a small portion of the total hearing
impaired population.

  Sensorineural hearing impairment occurs in the inner ear and/or neural
pathways and, the Company believes, accounts for the vast majority of hearing
impairment. In patients with sensorineural hearing impairment, the external
and middle ear function normally. The sound vibrations pass undisturbed
through the eardrum and ossicles, and fluid waves are created in the cochlea.
However, because some or many of the delicate sensory hair cells inside the
cochlea have degenerated or been damaged, the inner ear cannot detect the full
intensity and quality of the sound. Sensorineural hearing impairment typically
occurs as a result of aging or exposure to loud noise over a protracted period
of time.
 
  As people age, their level of hearing deteriorates and the dynamic range of
audible frequencies is compressed, especially at the higher frequencies. While
approximately 10% of the United States population is hearing impaired, based
on 1994 data, this percentage increases to an average of approximately 25% for
individuals over 55 years of age. The Company believes that with the growth
and aging of the population, the hearing impaired population will continue to
increase throughout the industrialized world. With the increasing exposure to
noise in modern society, it has been observed that people may experience noise
induced hearing loss from aircraft, automobiles, lawn mowers and high powered
stereo equipment as well as military service and machinery within the
workplace.
 
 Existing Therapies
 
  The traditional approaches to management of sensorineural hearing impairment
have been the use of hearing aids and cochlear implants. Hearing aids are the
most common devices used to manage mild to severe sensorineural hearing
impairment. Cochlear implants have been used for the narrow segment of the
sensorineural market represented by profound hearing impairment. However, both
approaches have significant limitations in addressing their respective
markets.
 
  Hearing Aids. The following table, based upon 1996 and 1997 articles in the
Hearing Journal, illustrates the ownership of traditional hearing aids by the
hearing impaired population in 1994. Approximately 18% of the hearing aid
owners did not use their device.

  Hearing aids are acoustic drive devices that amplify sound to increase the
movement of the tympanic membrane and thereby indirectly vibrate the ossicles
in an attempt to overcome the decrease in sensitivity of the delicate sensory
hair cells inside the cochlea. The first electrically enhanced hearing aid was
invented about a hundred years ago and consisted of a microphone, amplifier,
battery and speaker. More recently, hearing aid manufacturers have increased
the sophistication of sound processing, often using digital technology, to
provide features such as programmability and multi-band compression, allowing
different degrees of amplification at different frequencies. Hand-held
programmers have also been developed to compensate for the inability of
hearing aids to adequately process sound in a variety of acoustic
environments. In addition, as technology has enabled greater miniaturization,
less obtrusive hearing aids have become available. Although there have been
continued advancements in hearing aid device technology, for optimal
 
                                      27
<PAGE>
 
performance all or part of the device must fit tightly in the ear canal, which
results in significant drawbacks, including the following:
 
  Distorted sound quality. Obstructing the ear canal with either all or part
  of the hearing aid creates an effect known as occlusion, where outside
  sounds such as music are overwhelmed by internal sounds such as breathing
  or talking. Because the ear canal's natural resonance is significantly
  altered, the resulting sound can be unnatural and highly distorted.
 
  Acoustic feedback. Feedback is a high pitched squeal which results when a
  speaker and microphone are placed in close proximity and the sound from the
  speaker is loud enough to be picked up by the microphone. The problem of
  feedback is magnified since the volume of these devices must be turned up
  to not only compensate for the patient's hearing impairment but to overcome
  the reduction in sound caused by the blockage of the ear canal by the
  hearing aid. In addition, as hearing aids have been manufactured in smaller
  configurations, the problem of feedback has become inherently greater due
  to the closer proximity of the speaker to the microphone.
 
  Poor localization. Occlusion also results in the inability to differentiate
  the direction of sounds, as well as the inability to adequately
  differentiate between background noise and more important sounds, such as
  conversation.
 
  Social stigma. Many hearing aid users and potential users perceive a strong
  social stigma related to wearing a hearing aid.
 
  Discomfort. Hearing aids have been manufactured in smaller configurations
  in an attempt to address the perceived social stigma associated with
  wearing these devices. Since a tight fitting ear piece is required for
  optimal performance, the smaller versions of these devices must be placed
  deeper in the ear canal, which can cause substantial discomfort.
 
  Reliability. Hearing aids require frequent maintenance, in part due to
  their placement in the ear canal, where ear wax can cause problems with the
  speaker or dampen the sound produced by the hearing aid. Hearing aids
  generally have to be replaced every three or four years, either because of
  loss, damage or obsolescence. The need for periodic replacement increases
  the lifetime cost of wearing a hearing aid. Traditionally, most hearing aid
  users have paid for these devices directly.
 
  As a result of these problems, the benefits perceived by hearing aid users
are generally very low. An article in the 1996 Hearing Journal reported that
only approximately 53% of all hearing aid users are satisfied. Reflecting this
low level of user satisfaction, in 1996 hearing aid manufacturers experienced
product return rates ranging from 14% to 26%. Despite the inherent limitations
of hearing aids, in 1995, approximately 1.7 million hearing aids were sold in
the United States, representing a retail market of approximately $1.2 billion.
The United States market represents approximately 38% of the worldwide hearing
aid market. The Company estimates that the worldwide retail market for hearing
aids exceeded $3.0 billion in 1995.
 
  Cochlear Implants. Cochlear implants have been developed for people who have
a profound hearing loss and are essentially deaf. The cochlear implant is
inserted into the inner ear in a highly invasive and non-reversible surgery.
The implant electrically stimulates the auditory nerve through an electrode
array that provides audible cues to the user which are not interpreted by the
brain as normal sound. Instead, these cues have to be interpreted by the user,
and primarily aid in lipreading and alerting the user to very loud or
dangerous sounds. Users generally require intensive and extended counseling
and training following surgery to achieve any benefit. Best results are
achieved with adults whose hearing loss develops later in life or with
children. Cochlear implants have been controversial both because of strong
resistance from portions of the deaf community and because of the irreversible
nature of the surgery in which the cochlea is invaded and any residual hearing
is destroyed. Accordingly, the Company does not believe that cochlear implants
will achieve significant market penetration beyond their initial indication of
profound hearing impairment. The Company estimates that, in 1996, the
worldwide market for cochlear implants was under $100 million.

THE SYMPHONIX SOLUTION
 
  The Company is developing a family of proprietary semi-implantable and
implantable products, or soundbridges, for the management of moderate to
severe hearing impairment. The Company's family of Vibrant soundbridges is
based on its patented core technology, the Floating Mass Transducer ("FMT").
The FMT is a tiny transducer that is designed to enhance hearing by precisely
mimicking and amplifying the movements of the ossicles by converting sound
into mechanical vibrations. While conventional approaches have indirectly
driven the ossicles by amplifying sound to increase the vibrations of the
tympanic membrane, the FMT is attached directly to the ossicles and enhances
the natural movement of these vibratory structures. This in turn generates
enhanced stimulation of the delicate sensory hair cells in the inner ear. The
FMT receives electrical signals from an Audio Processor, which picks up sound
from the environment and converts these sounds into electrical signals. The
Audio Processor transmits the signals to an implant under the skin. As a
result, the ear canal is not obstructed, the natural resonance of the ear is
maintained and an amplified, natural sound quality is achieved.
 
  The Company's soundbridges are implanted in a two hour surgery that can be
performed on an outpatient basis utilizing the techniques which are similar to
those employed in routine otologic procedures. Based on preclinical studies,
the Company believes that the surgical procedure can be reversed without
clinically meaningful damage to the patient's residual hearing. The Company
believes that its family of Vibrant soundbridges offers a number of
significant benefits, including:
 
  Improved sound quality and speech intelligibility. By leaving the ear canal
  unobstructed and the natural resonance undisturbed, a more natural sound
  quality is obtained over a broader range of frequencies, and the user's
  ability to understand speech is expected to be greater.
 
  Elimination of acoustic feedback. Since the Vibrant soundbridge
  mechanically drives the ossicles, it does not generate any acoustic
  feedback.
 
  Improved sound localization. Users are able to comprehend the acoustic
  sound environment, identify specific sounds and their source and
  differentiate sounds from background noise.
 
  Minimized social stigma. In the semi-implantable versions of the Company's
  soundbridges, the only external component is located behind the ear and
  generally hidden by the user's hair. As a result, social stigma is
  minimized. The totally implantable versions of the Company's soundbridges
  are being designed with no external components, and aesthetic
  considerations would be completely eliminated.
 
  Improved comfort. No part of the Vibrant soundbridge is inserted in the ear
  canal, resulting in increased comfort for users of the Vibrant soundbridge.
 
  Improved reliability. Since no components of the Vibrant soundbridge will
  be within the ear canal, the reliability problems caused by wax and
  moisture are eliminated.
   
  Since the Company has not yet commercialized its products and since there
are no comparable direct drive devices currently available commercially, the
price that will be charged for the Vibrant soundbridge has not yet been
determined. However, the Company anticipates that the Vibrant soundbridge will
cost more than a sophisticated hearing aid (which can cost as much as $3,500),
but substantially less than a cochlear implant (the cost of which ranges from
approximately $17,000 to $30,000). The Company anticipates that surgical
procedure utilized in implanting the Vibrant soundbridge will cost
approximately $5,000 and will vary by geographic region.     
 
STRATEGY
 
  The Company's objectives are to establish its family of Vibrant soundbridges
as the standard of care worldwide for the management of moderate to severe
hearing impairment and to establish Symphonix as the leading company in the
hearing management market. The following are key elements of the Company's
strategy:
 
 
                                      29
<PAGE>
 
  Demonstrate improved quality of life. The Company intends to promote the
  potential benefits of its products to the hearing impaired population in
  order to expand the market to include not only current dissatisfied hearing
  aid users but also former users who have abandoned hearing aids due to
  either previous dissatisfaction or perceived social stigma. The Company
  believes that achieving real patient benefit in the form of improved
  quality of life will be an important factor in differentiating its products
  from the traditional approaches to hearing management.
 
  Develop surgeon endorsement of the Company's family of soundbridges. The
  Company intends to position the family of Vibrant soundbridges as
  technologically advanced implants that address an unmet patient need and
  add to the products and services that surgeons can offer. The Company's
  strategy is to market its soundbridges initially to those specialists in
  otology who are currently most active in ear surgery and, thereafter, to
  the general population of ENT surgeons. Because the surgical procedure for
  implementing the Vibrant soundbridge utilizes many of the same techniques
  employed by surgeons trained and experienced in cochlear implant surgery,
  the Company believes that surgeon training will not be a significant
  impediment to market acceptance.
 
  Leverage the Company's patented core technology. The Company intends to
  leverage its patented core FMT technology to develop new soundbridges and
  enhancements to its current technology. The Company intends to continue to
  dedicate significant resources to research and development to further
  develop its technology base and to expand the market it addresses through
  development of a family of alternate configurations of soundbridges. The
  Company is developing the Vibrant P soundbridge to permit a greater degree
  of customization to address the specific needs of a particular patient, the
  Vibrant D soundbridge to permit an even greater degree of customization
  along with the additional benefit of digital signal processing, and the
  Vibrant HF soundbridge to provide a benefit suited to those individuals who
  have a noise-induced hearing loss at high frequencies but relatively normal
  hearing at lower frequencies.
     
  Protect and enhance the Company's proprietary position. The Company intends
  to continue to aggressively pursue proprietary protection for its
  technologies and products. The Company has three patents issued in the
  United States and 21 patents pending both in the United States and
  internationally covering a number of fundamental aspects of the FMT and
  related technologies.     
 
PRODUCTS UNDER DEVELOPMENT
 
  Symphonix is developing proprietary semi-implantable and implantable
soundbridges, utilizing the Company's core FMT technology to manage hearing
impairment. The Company believes that the Vibrant soundbridge, Vibrant P
soundbridge, Vibrant HF soundbridge and Vibrant D soundbridge will enable the
Company to address a significant portion of the moderate to severe hearing
impairment market currently not satisfied with traditional hearing aid
devices. The Vibrant XP soundbridge has the potential to enable the Company to
address a portion of the profound hearing impairment market currently served
by cochlear implants. In addition, the Company is in the early stage of
developing the Vibrant TI which is being designed to be totally implantable
with no external components.
 
  The Vibrant soundbridge, Vibrant P soundbridge, Vibrant HF soundbridge and
Vibrant D soundbridge are designed to utilize the same implant, with the
differences in function being provided by modifications to the external Audio
Processor, its software and programming unit. Utilization of a common implant
will allow a user to upgrade the Audio Processor if a user's hearing changes
over time.

 Vibrant soundbridge
 
  The Company's initial product under development, the Vibrant soundbridge,
has both external and implantable components. The external Audio Processor
consists of (i) a microphone that picks up sound from the environment, (ii)
sound processing circuitry that converts the sound to an electronic signal and
modulates the signal to reduce potential noise interference from broad band
electromagnetic fields and (iii) a small 1.5 volt battery that powers the
device. The Audio Processor is placed on the skull behind the ear and is held
in place by magnetic attraction to an implanted receiver, the VORP (Vibrating
Ossicular Prosthesis). The Audio Processor is small enough to be concealed by
the user's hair.
 
               [ILLUSTRATION OF VIBRANT SOUNDBRIDGE IN PLACE] 
 
 
  The VORP converts the electronic signal to a mechanical vibration of the
ossicles in the middle ear. The VORP consists of (i) a receiver unit that
receives the electromagnetic signal through the skin from the external Audio
Processor and breaks down the electrical signal to the appropriate drive
signal for the FMT, (ii) a conductor link that connects the implanted receiver
unit to the FMT and (iii) the FMT itself, which is attached to the incus using
a titanium clip. All of these components are insulated from body chemistry
using well established implantable device materials used in pacemaker and
implantable defibrillator systems.
 
                                      32
<PAGE>

  The FMT is a tiny transducer, smaller than a grain of rice, that comprises a
floating magnet contained within a titanium housing. A coil surrounding the
housing generates a small electromagnetic field based on a signal received
from the VORP's receiver unit. The electromagnetic interaction of the magnet
and the coil creates a mechanical vibration of the entire FMT. This vibration
enhances the natural movement of the ossicles, which in turn generates
enhanced stimulation of the delicate sensory hair cells in the inner ear. A
critical element of the proprietary FMT design is the proximity of the magnet
to the electromagnetic field that causes the magnet to vibrate. By keeping the
magnet and the coil close together, the FMT maximizes electromagnetic coupling
while minimizing power consumption.
 
 
                  [LOGO OF PRODUCT ILLUSTRATION APPEARS HERE]
   
  The surgical procedure for the implantation of the Vibrant soundbridge
involves techniques which are similar to those employed in other common
otologic procedures. The internal receiver unit is implanted below the skin
and muscle behind the ear. The conductor link connecting the receiver unit to
the FMT is placed through the excavated mastoid bone. These steps are similar
to those required for the surgical placement of a cochlear implant receiver.
In the middle ear, the FMT is attached to the ossicles in a manner similar to
the way otologists have traditionally attached ossicular prostheses for
management of conductive hearing loss. Because the surgery involves surgical
techniques that are familiar to ear surgeons, the Company believes that
surgeon training will not be a significant impediment to market acceptance.
The procedure may be performed on an outpatient basis, and initial clinical
experience has indicated that the procedure can be performed in about two
hours. Approximately eight weeks following the surgery, the Audio Processor is
fitted by an audiologist with the appropriate sound processing settings. The
Company's approved IDE only permits implantation in one ear. This will
generally be the ear with the poorest unaided functional hearing. Based on
preclinical studies, the Company believes that the surgical procedure can be
reversed without damage to the patient's residual hearing.     
   
  Limited clinical trials of the Vibrant soundbridge were initiated in late
1996 in the United States. Also in late 1996, an EN 540 clinical trial was
initiated in Europe, which trial has subsequently been completed. The Company
has since submitted the technical, preclinical and clinical data that it
believes will be necessary, together with the previously obtained
certifications, to satisfy the applicable regulatory requirements for
commercial sales in the EU. As of January 5, 1998, five patients in the United
States have been implanted with the Vibrant soundbridge, all of whom have had
the Audio Processor fitted and the soundbridge's performance evaluated.
Additionally, 19 patients in Europe have been implanted with the Company's
Vibrant soundbridge, all of whom have had the Audio Processor fitted and the
soundbridge's performance evaluated.     
 
 Vibrant P soundbridge
 
  The Vibrant P soundbridge under development is similar to the Vibrant
soundbridge but is designed to permit a greater degree of customization to
address the specific needs of a particular
 
                                      33
<PAGE>
 
user's hearing loss and expand the types of hearing loss that can be managed
by the Company's products. At the time of fitting, the Audio Processor is
connected to a hand-held programming unit which allows the audiologist to
adjust separately the low and high frequencies. This permits a greater degree
of customization in either the high or low frequency band.
   
  The Company received approval to incorporate the Vibrant P soundbridge into
its current European clinical trial of the Vibrant soundbridge and this trial
was initiated in July 1997. In the United States, the Company filed an IDE
supplement on November 14, 1997 summarizing the Phase I results, finalizing
the study protocol and labeling claims, providing technical information
regarding the Vibrant P soundbridge, and requested permission to proceed to
the pivotal study. On December 11, 1997, the FDA approved the multi-center
pivotal study in 55 subjects at up to 12 sites with the Vibrant P soundbridge.
There can be no assurance that the Company's clinical trial effort will
progress as expected, will not be delayed or that such effort will lead to the
successful development of any product. As of January 5, 1998, 24 patients have
been implanted with the Vibrant P soundbridge in Europe, of whom 20 have had
the Audio Processor fitted and the soundbridge's performance evaluated.     
 
 Vibrant HF soundbridge
   
  The Vibrant HF soundbridge is being developed to provide a benefit for those
individuals who have a hearing loss at high frequencies but relatively normal
hearing at lower frequencies. Hearing aids usually are limited in
effectiveness at higher frequencies due to acoustic feedback and internal
speaker response. With the increasing exposure to noise in modern society, it
has been observed that people may experience noise-induced hearing loss from
aircraft, automobiles, lawn mowers and high powered stereo equipment as well
as military service and machinery within the workplace. The Vibrant HF
soundbridge will be configured through selective signal processing. The
Company intends to submit an IDE in 1998 for FDA approval to commence clinical
trials of the Vibrant HF soundbridge and intends to initiate European clinical
trials in 1998.     
 
 Vibrant D soundbridge
   
  The Vibrant D soundbridge under development is similar to the Vibrant P
soundbridge, but is designed to permit an even greater degree of customization
to address the specific needs of a particular user's hearing loss. The Vibrant
D soundbridge features digital signal processing. Fully automatic and
independent sound processing in three separate frequency bands is provided. At
the time of fitting, the Audio Processor is connected to a programming unit
which allows the audiologist to adjust separately the low, mid and high
frequencies. This sophisticated system will be capable of analyzing sound and
automatically adjusting the soundbridge's response.     
   
  The Company intends to seek approval of an IDE supplement for the Vibrant D
soundbridge during 1998 and to initiate European clinical trials in 1998.
There can be no assurance, however, that the Company will not be required to
submit a separate IDE for the Vibrant D soundbridge, which would result in a
delay in regulatory approval.     
 
 Vibrant XP soundbridge
 
  The Vibrant XP soundbridge is being developed to provide a benefit for those
individuals who have a severe to profound hearing loss with speech recognition
above 30%. Currently, there are only limited treatment options for such
individuals.
   
  The Vibrant XP soundbridge will be configured to provide modified signal
processing and higher output from the FMT, thereby providing additional
benefit for certain people with a severe to profound hearing impairment.
Generating this higher output will require an external body-worn

battery pack, similar to those used for cochlear implants. However, unlike
cochlear implants, the Vibrant XP soundbridge will not require penetration of
the inner ear with its attendant damage to residual hearing.     
   
  The Company intends to conduct a feasibility study in 1998 on a limited
number of patients in Europe to assess the viability of this product concept.
Based on the results of this feasibility study, the Company may seek approval
to initiate U.S. clinical trials of the Vibrant XP soundbridge by submitting
an IDE during 1998 and may initiate European clinical trials in 1998.     
 
 Vibrant TI soundbridge
   
  The Company is in the early stages of developing versions of the Vibrant
soundbridge for the management of moderate to severe hearing impairment that
are totally implantable with no external components. The essential functions
of the core FMT technology of these products will be the same as in the semi-
implantable products. However, all the functions currently performed by the
external Audio Processor are being designed to be performed by implanted
components. The Company believes that the Vibrant TI soundbridge, if
successfully developed, will be applicable especially for people who are
particularly physically active or who are concerned about aesthetics.     
   
  Two critical elements of producing the Vibrant TI soundbridge are the
development of an implantable microphone that can adequately pick up sound
from the external environment, and the development of a transcutaneously
rechargeable battery to power the device. The microphone is being developed
internally by the Company and the battery is being developed under a
cooperative development project with a specialized battery manufacturer.
However, there can be no assurance that such components will be successfully
developed in a timely manner, if ever.     
 
  Since all of the Company's products are in development, significant revenues
from product sales will not be realized for at least several years, if ever.
There can be no assurance that any of the Company's product development
efforts will be successfully completed, that any of the Company's products
will be proven to be safe and effective, that regulatory approvals will be
obtained or labeling claims will be as broad as sought, that the Company's
products will be capable of being produced in commercial quantities with
acceptable yields at reasonable costs, or that any products, if introduced,
will achieve market acceptance.
 
CLINICAL TRIAL ACTIVITIES
 
 United States
   
  On February 23, 1996, the Company received approval of an IDE for the
Vibrant soundbridge from the FDA. The Company has completed a Phase I trial
under the IDE and submitted the interim report to the FDA. This trial was
limited to five subjects, including Geoffrey R. Ball, a founder of the
Company, at two investigational sites and was intended to test the safety and
provide preliminary evidence of efficacy of the device and the surgical
procedures used to implant the device. Due to the limited number of subjects
evaluated, no statistically valid conclusions can be made from the results
reported to the FDA.     
   
  The Company observed the following performance characteristics: increased
functional gain at higher frequencies (i.e., >2000 Hz); elimination of
occlusion effect; elimination of acoustic feedback; elimination of placement
loss; reduction of maintenance issues; and elimination of ear mold issues. A
standardized hearing test was also administered to evaluate each subject's
ability to comprehend speech in a noisy environment. Three of the five
subjects demonstrated a 50% improvement with the Vibrant soundbridge compared
to their hearing aid. The trial included a self-assessment questionnaire of
improvement for the following seven categories of device performance as
compared to a hearing aid: communication, reverberation, familiar talker,
reduced cues, background noise, aversion to sounds and distortion of sounds.
Subjects reported an improvement greater than 20% in six of the seven
categories with the Vibrant soundbridge when compared to their current hearing
aid.     
 
                                      35
<PAGE>
 
          
  On November 14, 1997, the Company filed an IDE supplement summarizing the
Phase I results, finalizing the study protocol and labeling claims, providing
technical information regarding the Vibrant P soundbridge, and requested
permission to proceed to the pivotal study. On December 11, 1997, the FDA
approved the multi-center pivotal study in 55 subjects at up to 12 sites with
the second generation Vibrant P soundbridge.     
 
 Europe
   
  The Company has conducted a multi-center EN 540 clinical trial in Europe at
seven institutions. Clinical sites were located in Germany, Italy, the
Netherlands, the United Kingdom, Switzerland and France. The EN 540 protocol
investigated the safety and performance of the Vibrant soundbridge and the
Vibrant P soundbridge. As of January 5, 1998, 43 subjects have been implanted
with the Company's soundbridges, 19 with the Vibrant soundbridge and 24 with
the Vibrant P soundbridge. With the Vibrant soundbridge, performance was only
evaluated for functional gain and the results were comparable to those
achieved by the subjects in the United States trial. With the Vibrant P
soundbridge, the subjects demonstrated functional gains as high as 50 dB at
1000 Hz, 55 dB at 1500 Hz, 60 dB at 2000 Hz, 40 dB at 3000 Hz, 50 dB at
4000 Hz, 40 dB at 6000 Hz, and 35 dB at 8000 Hz. These functional gain values
reported were at "user settings" and did not necessarily reflect the maximum
functional gains attainable with the device.     
   
  There can be no assurance that the Company's clinical trial efforts will
progress as expected, not be delayed or that such efforts will lead to the
successful development of any product. No assurance can be given that any of
the Company's proposed clinical trials will continue to be allowed by the FDA
or other regulatory agencies or that clinical trials will commence as planned.
Any delays in the Company's clinical trials would have a material adverse
effect on the Company's business, financial condition and results of
operations. Success in preclinical studies or early stage clinical trials does
not assure success in later stage clinical trials. Data obtained from
preclinical and clinical activities are susceptible to varying interpretations
which could delay, limit or prevent regulatory approval. Further, there can be
no assurance that if such testing of products under development is completed,
any such devices will be accepted for formal review by the FDA or approved by
the FDA for marketing in the United States.     
 
RESEARCH AND DEVELOPMENT
   
  The Company had 23 employees engaged in research and development, including
regulatory and clinical affairs, as of December 31, 1997. The Company's
research and development has focused on developing its patented core FMT
technology, developing the Vibrant soundbridge and conducting appropriate
preclinical and clinical testing. The Company expended approximately $5.4
million and $6.4 million for the years ended December 31, 1996 and 1997,
respectively, on research and development, and anticipates that it will
continue to expend substantial resources on completion of the clinical testing
of the Vibrant and Vibrant P soundbridges, development and clinical testing of
the Vibrant HF and Vibrant D soundbridges, and supporting manufacturing scale-
up. In addition, the Company expects to devote substantial resources to the
development of the Vibrant XP soundbridge and of the Vibrant TI soundbridge
family of totally implantable versions of the Vibrant soundbridge. In
addition, the Company may devote resources for the development of products for
the treatment of conductive hearing loss. Product development involves a high
degree of risk and there can be no assurance that the Company's product
development efforts will result in any commercially successful products.     
 
MANUFACTURING
 
  The Company currently manufactures its products in limited quantities for
laboratory testing and for its United States and European clinical trials. The
manufacture of the Company's soundbridges is
 
                                      36
<PAGE>
 
   
a complex operation involving a number of separate processes, components and
assemblies. Each device is assembled and individually tested by the Company.
The manufacturing process consists primarily of assembly of internally
manufactured and purchased components and subassemblies, and certain processes
are performed in an environmentally controlled area. After completion of the
manufacturing and testing processes, implantable devices are sterilized by a
sub-contracted supplier. The Company has no experience manufacturing its
products in the volumes or with the yields that will be necessary for the
Company to achieve significant commercial sales, and there can be no assurance
that the Company can establish high volume manufacturing capacity or, if
established, that the Company will be able to manufacture its products in high
volumes with commercially acceptable yields. If the Company receives
regulatory approval to commercialize its products, it will need to expend
significant capital resources and develop manufacturing expertise to establish
commercial-scale manufacturing capabilities. Furthermore, prior to approval of
a PMA, the Company's facilities, procedures and practices will be subject to a
pre-approval inspection by the FDA. The Company's inability to successfully
manufacture or commercialize its soundbridges in a timely matter could have a
material adverse effect on the Company's business, financial condition and
results of operations.     
   
  Raw materials, components and subassemblies for the Company's soundbridges
are purchased from various qualified suppliers and are subject to stringent
quality specifications and inspections. The Company conducts quality audits of
its key suppliers, several of whom are experienced in the supply of components
to manufacturers of implantable medical devices, such as pacemakers,
defibrillators and drug delivery pumps. A number of components and
subassemblies, such as silicone, control electronics and implant packaging are
provided by single source suppliers. One component, the signal processing
microcircuit, is provided by a sole source supplier, Gennum Corporation. None
of the Company's suppliers is contractually obligated to continue to supply
the Company nor is the Company contractually obligated to buy from a
particular supplier. For certain of these components and subassemblies, there
are relatively few alternative sources of supply, and establishing additional
or replacement suppliers for such components and subassemblies could not be
accomplished quickly. In addition, if the Company wishes to significantly
modify its manufacturing processes or change the supplier of a critical
component, additional approvals will be required from the FDA before the
change can be implemented. Because of the long lead time for some components
and subassemblies that are currently available from a single source, a
supplier's inability or failure to supply such components or subassemblies in
a timely manner or the Company's decision to change suppliers could have a
material adverse effect on the Company's business, financial condition and
results of operations.     
   
  Although the Company believes that its current facilities are sufficient to
meet its clinical manufacturing needs, before the Company commences
commercial-scale manufacturing operations, it intends to move to a new
facility. The Company has signed a lease on a new facility and is in the
process of constructing an evironmentally controlled area and other leasehold
improvements in this building and expects to occupy the building in the first
quarter of 1998. This new facility, which will replace the current facility,
is necessary for the establishment of commercial-scale manufacturing.     
 
  The Company's manufacturing facilities are subject to periodic inspection by
regulatory authorities, and its operations must undergo QS regulation
compliance inspections conducted by the FDA and corresponding state agencies.
Additionally, prior to approval of a PMA, the Company's and its third-party
manufacturers' facilities, procedures and practices will be subject to pre-
approval QS regulation inspections. The Company has been inspected by the Food
and Drug Branch of the California Department of Health Services ("CDHS") and a
Device Manufacturing License has been issued to the Company. The Company will
be required to comply with the QS regulation requirements in order to produce
products for sale in the United States and with applicable quality system
standards and directives in order to produce products for sale in the EU. Any
failure of the Company to comply with the QS regulation or applicable
standards and directives may result in the Company being required to take
corrective actions, such as modification of its policies and
 
                                      37
<PAGE>
 
procedures. Pending such corrective actions, the Company could be unable to
manufacture or ship any products, which could have a material adverse effect
on the Company's business, financial condition and results of operations.
 
SALES, MARKETING AND TRAINING
 
  The primary market for the Vibrant soundbridge is well defined and highly
concentrated. Of the approximately 8,000 ENT surgeons in the United States,
approximately 400 are specialists in otology. The Company's strategy is to
market its products initially to those specialists in otology who are
currently most active in ear surgery, and, subsequently, to the general
population of ENT surgeons. Because the surgical procedure for implementing
the Vibrant soundbridge utilizes many of the same techniques employed by
surgeons trained and experienced in cochlear implant surgery, the Company
believes that surgeon training will not be a significant impediment to market
acceptance.
 
  The Company intends to position the family of Vibrant soundbridges as
technologically advanced implants that address an unmet patient need and add
to the products and services that surgeons can offer. Patients who have
traditionally been candidates for a hearing aid often are first seen by an ENT
surgeon, prior to being referred to a hearing device dealer or dispensing
audiologist. Accordingly, endorsement by the surgical community will be an
important goal of the Company's marketing programs. The Company will also seek
to develop a high degree of awareness by and endorsement from audiologists.
 
  The Company intends to promote the benefits of its products to consumers in
order to expand usage to include not only those who are currently dissatisfied
with hearing aids, but also those who have abandoned hearing aids due to
either dissatisfaction or perceived social stigma.
   
  Because the target market is quite concentrated, the Company believes that
it can address the market in the United States with a small direct sales
force. The Company is in the process of establishing a sales and marketing
organization in Europe. An office has been established in Basel, Switzerland,
where the Company's Director of European Sales and Marketing and European
Clinical Manager are based. The Company has recruited sales personnel to
provide direct sales coverage in Germany, France and the United Kingdom, who
will commence their employment during the first quarter of 1998. By the end of
the first quarter of 1998, the Company intends to establish distributors in
Italy, Spain and the Benelux countries. In other international markets,
including Japan, the Company will seek to establish a network of distributors.
There can be no assurance that the Company will be able to build a direct
sales force or marketing organization in any country, that establishing a
direct sales force or marketing organization will be cost-effective or that
the Company's sales and marketing efforts will be successful. In addition, the
Company has had discussions with only a limited number of potential
international distributors and has not yet entered into any agreements with
distributors. There can be no assurance that the Company will be able to enter
into agreements with qualified distributors on a timely basis on terms
acceptable to the Company, or at all, or that such distributors will devote
adequate resources to selling the Company's products.     
 
COMPETITION
 
  The medical device industry is subject to intense competition in the United
States and abroad. The Company believes its products will compete primarily
with the traditional approaches to managing hearing impairment, principally
hearing aids. Principal manufacturers of acoustic hearing aids include Siemens
Hearing Instruments, Inc., Philips Medical Systems North America Co., Starkey
Laboratories Inc., Beltone Electronics Corp., Dahlberg Inc., ReSound Corp.,
Oticon, Inc., Widex Hearing Aid Co., Inc. and Phonak Inc. There can be no
assurance that the Company's soundbridges will be able to successfully compete
with established hearing aid products. Although, to the Company's knowledge,
none of these acoustic hearing aid manufacturers are currently developing
 
                                      38
<PAGE>
 
direct drive devices, there can be no assurance that these potential
competitors will not succeed in developing technologies and products in the
future that are more effective, less expensive than those being developed by
the Company or that do not require surgery. The Company is aware of several
university research groups and development-stage companies that have active
research or development programs related to direct drive sensorineural hearing
devices. Research of this type has been conducted at various sites for over 20
years. In addition, some large medical device companies, some of which are
currently marketing implantable medical devices, may develop programs in
hearing management. Certain of these companies have substantially greater
financial, technical, manufacturing, marketing and other resources than the
Company. In addition, there can be no assurance that certain of the Company's
competitors will not develop technologies and products that may be more
effective in managing hearing impairment than the Company's products or that
render the Company's products obsolete.
   
  The Company believes that the primary competitive factors in the hearing
management market will be the quality of the hearing enhancement, safety,
whether surgery is required, reliability, endorsement by the surgeon and
audiology communities, patient comfort, cosmetic result and price. The Company
believes that it will be competitive with respect to these factors.
Nonetheless, because the Company's products are still under development, the
relative competitive position of the Company in the future is difficult to
predict.     
   
  The medical device industry is characterized by rapid and significant
technological change. Accordingly, the Company's success will depend in part
on its ability to respond quickly to medical and technological change and user
preference through the development and introduction of new products that are
of high quality and that address patient and surgeon requirements.     
 
PATENTS AND PROPRIETARY TECHNOLOGY
   
  In the United States, the Company holds three issued patents and 11 pending
patent applications. Additionally, the Company has ten pending foreign patent
applications. These patents and patent applications generally cover the
invention and application of the FMT as well as the specific application of
the FMT and other concepts in the field of hearing impairment. In addition,
the Company has licensed, on a royalty-free basis, a United States patent
covering the magnetic attachment of an external audio processor to an
implanted receiver. The Company's success will depend in part on its ability
to obtain patent protection for its products and processes, to preserve its
trade secrets, and to operate without infringing or violating the proprietary
rights of others.     
 
  The patent positions and trade secret provisions of medical device
companies, including those of the Company, are uncertain and involve complex
and evolving legal and factual questions. The coverage sought in a patent
application either can be denied or significantly reduced before or after the
patent is issued. Consequently, there can be no assurance that any patents
from pending applications or from any future patent application will be
issued, that the scope of the patent protection will exclude competitors or
provide competitive advantages to the Company, that any of the Company's
patents will be held valid if subsequently challenged or that others will not
claim rights in or ownership of the patents and other proprietary rights held
by the Company. Since patent applications are secret until patents are issued
in the United States or corresponding applications are published in other
countries, and since publication of discoveries in the scientific or patent
literature often lags behind actual discoveries, the Company cannot be certain
that it was the first to file patent applications for such inventions.
 
  In addition, there can be no assurance that competitors, many of which have
substantial resources, will not seek to apply for and obtain patents that will
prevent, limit or interfere with he Company's ability to make, use or sell its
products either in the United States or in international markets. Although the
Company has conducted searches of patents issued to other companies,
 
                                      39
<PAGE>
 
research or academic institutions or others, there can be no assurance that
such patents do not exist, have not been filed or could not be filed or
issued, which contain claims relating to the Company's technology, products or
processes. Patents issued and patent applications filed in the United States
or internationally relating to medical devices are numerous and there can be
no assurance that current and potential competitors and other third parties
have not filed or in the future will not file applications for, or have not
received or in the future will not receive, patents or obtain additional
proprietary rights relating to products or processes used or proposed to be
used by the Company. In addition, patent applications in foreign countries are
maintained in secrecy for a period after filing. Publication of discoveries in
the scientific or patent literature tends to lag behind actual discoveries and
the filing of related patent applications. There may be pending applications,
which if issued with claims in their present form, might provide proprietary
rights to third parties relating to products or processes used or proposed to
be used by the Company. The Company may be required to obtain licenses to
patents or proprietary rights of others. Further, the laws of certain foreign
countries do not protect the Company's intellectual property rights to the
same extent as do the laws of the United States. Litigation or regulatory
proceedings, which could result in substantial cost and uncertainty to the
Company, may also be necessary to enforce patent or other intellectual
property rights of the Company or to determine the scope and validity of other
parties' proprietary rights. There can be no assurance that the Company will
have the financial resources to defend its patents from infringement or claims
of invalidity.
 
  The Company also relies upon trade secrets and other unpatented proprietary
technology, and no assurance can be given that others will not independently
develop substantially equivalent proprietary information and techniques or
otherwise gain access to or disclose the Company's proprietary technology or
that the Company can meaningfully protect its rights in such unpatented
proprietary technology. The Company's policy is to require each of its
employees, consultants, investigators and advisors to execute a
confidentiality agreement upon the commencement of an employment or consulting
relationship with the Company. These agreements generally provide that all
inventions conceived by the individual during the term of the relationship
shall be the exclusive property of the Company and shall be kept confidential
and not be disclosed to third parties except in specified circumstances. There
can be no assurance, however, that these agreements will provide meaningful
protection for the Company's proprietary information in the event of
unauthorized use or disclosure of such information.
 
  Recently Public Law 104-208 was signed into law in the United States and
limits the enforcement of patents relating to the performance of surgical or
medical procedures on a body. This law precludes medical practitioners and
health care entities, who practice these procedures, from being sued for
patent infringement. Therefore, depending upon how these limitations are
interpreted by the courts, they could have a material adverse effect on the
Company's ability to enforce any of its proprietary methods or procedures
deemed to be surgical or medical procedures on a body. In certain other
countries outside the United States, patent coverage relating to the
performance of surgical or medical procedures is not available. Therefore,
patent coverage in such countries will be limited to the FMT or to narrower
aspects of the FMT.
 
  The medical device industry in general has been characterized by substantial
litigation. Litigation regarding patent and other intellectual property
rights, whether with or without merit, could be time-consuming and expensive
to respond to and could distract the Company's technical and management
personnel. The Company may become involved in litigation to defend against
claims of infringement by the Company, to enforce patents issued to the
Company or to protect trade secrets of the Company. If any relevant claims of
third-party patents are held as infringed and not invalid in any litigation or
administrative proceeding, the Company could be prevented from practicing the
subject matter claimed in such patents, or would be required to obtain
licenses from the patent owners of each such patent, or to redesign its
products or processes to avoid infringement. In addition, in the
 
                                      40
<PAGE>
 
event of any possible infringement, there can be no assurance that the Company
would be successful in any attempt to redesign its products or processes to
avoid such infringement or in obtaining licenses on terms acceptable to the
Company, if at all. Accordingly, an adverse determination in a judicial or
administrative proceeding or failure by the Company to redesign its products
or processes or 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. Although the Company has not been involved in any litigation to
date, in the future, costly and time-consuming litigation brought by the
Company may be necessary to enforce patents issued to 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.
 
GOVERNMENT REGULATION
 
  The Company's medical products, such as the Vibrant soundbridge, are
regulated as medical devices. Accordingly, clinical trials, product
development, labeling, manufacturing processes and promotional activities are
subject to extensive review and rigorous regulation by government agencies in
most countries in which the Company will seek to commercialize its products.
 
 United States
 
  In the United States, the Company's products are subject to applicable
provisions of the United States Federal Food, Drug, and Cosmetic Act ("FDC
Act"), and other federal statutes and regulations governing, among other
things, the design, manufacture, testing, safety, labeling, storage, record
keeping, reporting, approval, advertising and promotion of medical devices.
Noncompliance with applicable requirements can result in warning letters,
fines, recalls or seizure of products, civil penalties, injunctions, total or
partial suspension of production, withdrawal of approval or refusal to approve
new marketing applications and criminal prosecution. Changes in existing
requirements or adoption of new requirements could have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
  Pursuant to the FDC Act, the FDA regulates the design, manufacture,
distribution, preclinical and clinical study and approval of medical devices
in the United States. Medical devices are classified in one of three classes
(Class I, Class II or Class III) on the basis of the controls necessary to
reasonably assure their safety and effectiveness. Safety and effectiveness is
considered to be reasonably assured for Class I devices through general
controls (e.g., labeling, premarket notification and adherence to current QS
regulations) and for Class II devices through the use of additional special
controls (e.g., performance standards, post-market surveillance, patient
registries and FDA guidelines).
 
  Generally, Class III devices are those which must receive premarket approval
by the FDA to reasonably assure their safety and effectiveness (e.g., life-
sustaining, life-supporting and implantable devices, or new devices which have
been found not to be substantially equivalent to legally marketed devices, or
devices whose safety and effectiveness cannot be reasonably assured through
general controls, even if supplemented by additional special controls). Active
implantable devices, such as the Company's implantable hearing devices, are
considered Class III devices.
 
  Before a new device can be introduced to the market, the manufacturer
generally must obtain FDA clearance through a 510(k) Premarket Notification or
FDA approval through a PMA application. While the Company has no products for
which it expects to seek 510(k) clearance, it may file 510(k) submissions with
respect to future products. A 510(k) clearance will generally only be granted
if the information submitted to the FDA establishes that the device is
"substantially equivalent" to a legally marketed predicate medical device.
Frequently, the FDA will require clinical data in support of a 510(k)
submission, and the 510(k) process can become time-consuming and expensive.
Significant modifications of the labeling, manufacturing and design of any
product that has been cleared through
 
                                      41
<PAGE>
 
the 510(k) process will require a new 510(k) Premarket Notification, if those
modifications could significantly affect the safety, effectiveness or intended
use of the device.
 
  A PMA must be submitted if the device cannot be cleared through the 510(k)
process. A PMA must be supported by extensive data, including, but not limited
to, technical, preclinical, clinical trials, manufacturing, and labeling to
demonstrate the safety and effectiveness of the device. The Company believes
that all versions of the Vibrant soundbridge currently under development are
Class III devices and will require a PMA, as will future configurations of
implantable hearing devices.
          
  Before the Company's products can be commercialized in the United States,
the Company must submit, in a PMA, extensive data on preclinical studies and
clinical trials, device design, manufacturing, labeling, promotion and
advertising, as well as other aspects of the product. In addition, the Company
must submit clinical data gathered in trials conducted under an IDE
demonstrating to the satisfaction of the FDA that the product is safe and
effective for its labeling claims, and obtain marketing approval from the FDA.
Phase I of the IDE study has been completed. Phase I was limited to two sites
and five subjects and was intended to test the safety and provide preliminary
evidence of the effectiveness of the device and the surgical procedure used to
implant the device. On November 14, 1997, the Company filed an IDE supplement
summarizing the Phase I results, finalizing the study protocol and labeling
claims, providing technical information regarding the Vibrant P soundbridge,
and requested permission to proceed to the pivotal study. On December 11,
1997, the FDA approved the multi-center pivotal study in 55 subjects at up to
12 sites with the second generation Vibrant P soundbridge. There can be no
assurance that the Company's clinical trial effort will progress as expected,
will not be delayed or that such effort will lead to the successful
development of any product. No assurance can be given that any of the
Company's clinical trials will continue to be allowed by the FDA or other
regulatory agencies or that clinical trials will commence as planned.     
 
  Any delays in the Company's clinical trials would have a material adverse
effect on the Company's business, financial condition and results of
operations. Success in preclinical studies or early stage clinical trials does
not assure success in later stage clinical trials. Data obtained from
preclinical and clinical activities are susceptible to varying interpretations
which could delay, limit or prevent regulatory approval. Further, there can be
no assurance that if such testing of products under development is completed,
any such devices will be accepted for formal review by the FDA, or approved by
the FDA for marketing in the United States.
 
  After a PMA is filed, the FDA begins its review of the submitted
information, which generally takes between one and two years, but may take
significantly longer. During this review period, the FDA may request
additional information or clarification of information already provided. Also
during the review period, an advisory panel of experts from outside the FDA
will be convened to review and evaluate the application and provide
recommendations to the FDA as to the approvability of the device. In addition,
the FDA will conduct a preapproval inspection of the manufacturing facility to
ensure compliance with QS regulation requirements. There can be no assurance
that the Company will be able to meet the FDA's requirements or that any
necessary approval will be granted in a reasonable time frame, or at all.
 
  New PMAs or PMA supplements are required for significant modifications to
the manufacture, labeling and design of a device that is approved through the
PMA process. Supplements to a PMA often require submission of the same type of
information as a PMA, except that the supplement is limited to information
needed to support any changes from the device covered by the original PMA and
may not require as extensive clinical data or the convening of an advisory
panel.
 
  The PMA process can be expensive, uncertain and can frequently require
several years. Even when a PMA is approved, the FDA may impose restrictions on
the indications for which the device
 
                                      42
<PAGE>
 
can be marketed. There can be no assurance that the Company will be able to
obtain necessary approvals on a timely basis, or at all, and delays in
obtaining or failure to obtain such approvals, the loss of previously obtained
approvals, or failure to comply with existing or future regulatory
requirements could have an adverse effect on the Company's business, financial
condition and results of operations.
   
  Subsequent to the receipt of an FDA approval, the Company will continue to
be regulated by the FDA with regard to the reporting of adverse events related
to its products, and ongoing compliance with QS regulation. The Company's
manufacturing facility must be registered with the FDA and the CDHS and will
be subject to periodic inspections by the FDA and by the CDHS. A Device
Manufacturing License has been issued by the State of California and this
license must be renewed annually for the Company to continue manufacture of
medical devices in California.     
 
 Europe
 
  The primary regulatory environment in Europe is that of the EU which
consists of 15 countries encompassing most of the major countries in Europe.
The EU has adopted numerous directives and standards regulating the design,
manufacture, clinical trial, labeling, and adverse event reporting for medical
devices. The principal directives prescribing the laws and regulations
pertaining to medical devices in the EU are the MDD and the AIMDD. In the EU,
the Company's soundbridges will be regulated as active implantables and
therefore be governed by the AIMDD. For products, such as those of the
Company, that have not previously been commercialized in the EU, CE marking is
required prior to initiation of sales in the EU. Certain other countries, such
as Switzerland, have voluntarily adopted laws and regulations that mirror
those of the EU with respect to medical devices.
 
  Devices that comply with the requirements of a relevant directive will be
entitled to bear CE conformity marking, indicating that the device conforms
with the essential requirements of the applicable directive, and accordingly,
can be commercially distributed throughout the EU. The method of assessing
conformity varies depending on the class of the product, but normally involves
a combination of self-assessment by the manufacturer and a third-party
assessment by a Notified Body. This third party assessment may consist of an
audit of the manufacturer's quality system and specific testing of the
manufacturer's product. An assessment by a Notified Body in one country within
the EU is required in order for a manufacturer to commercially distribute the
product throughout the EU.
   
  For purposes of determining the necessary steps for assessing conformity,
devices are classified under the Directives as Class I, Class IIa, Class IIb,
Class III, or Active Implantable Medical Devices. Devices having a higher
classification are considered to have a higher risk and, accordingly, are
subject to more controls in order to bear CE marking. The Vibrant soundbridge
is designated as an Active Implantable Medical Device. Essential requirements
under the AIMDD include substantiating that the device meets the
manufacturer's performance claims and that safety issues, if any, constitute
an acceptable risk when weighed against the intended benefits of the device.
The two principal aspects of assessing conformity for Active Implantable
Medical Devices are determinations from the Notified Body that the processes
employed in the design and manufacture of a device qualify as a full quality
system in compliance with applicable standards (e.g., EN ISO 9001, EN 46001
and 90/385/EEC), and that the technical, preclinical, and clinical data
gathered on the device are adequate to support CE marking.     
   
  The Company has undergone an inspection by its Notified Body and its quality
system has been certified by the Notified Body as being in compliance with the
required standards. The Company has submitted the technical, preclinical and
clinical data that its Notified Body has indicated will be required to satisfy
the essential requirements of the AIMDD. To satisfy these requirements, the
Company must complete a clinical trial conducted under European clinical trial
standards (EN 540)     
 
                                      43
<PAGE>
 
   
to determine the safety and performance of the products. The Company must
continue to pass annual EN ISO 9001, EN 46001 and AIMDD 2.3 quality system
audits in order to retain international approvals. As of January 5, 1998, a
total of 43 patients in the European clinical trial have been implanted with
the Company's soundbridges (19 with the Vibrant and 24 with the Vibrant P) of
whom 39 have had the Audio Processor fitted and the soundbridge's performance
evaluated. There can be no assurance that such data will be accepted by the
Company's Notified Body, or that the Notified Body will not require the
Company to obtain additional data from additional clinical trials involving
more patients in order to demonstrate the safety and performance of the
Vibrant and the Vibrant P soundbridges.     
 
  Once a manufacturer has satisfactorily completed the regulatory compliance
tasks required by the directives and received favorable determinations by the
Notified Body, it is eligible to place the CE mark on its products.
Manufacturers are subject to ongoing regulation under the AIMDD. The quality
system will be subject to periodic audit and recertification, and serious
adverse events must be reported to the authorities in the country where the
incident takes place. If such incidents occur, the manufacturer may have to
take remedial action, including withdrawal of the product from the EU market.
 
  While no additional premarket approvals in individual EU countries are
required, prior to the marketing of a device bearing the CE mark, practical
complications with respect to market introduction may occur. For example,
differences among countries have arisen with regard to labeling requirements.
Also, as the directives do not cover reimbursement and distribution practices,
differences may occur in these and other areas.
 
THIRD-PARTY REIMBURSEMENT
 
  The Company believes that its products will generally be purchased by
hospitals and clinics upon the recommendation of a surgeon. In the United
States, hospitals, physicians and other health care providers that purchase
medical devices generally rely on third-party payors, principally Medicare,
Medicaid, private health insurance plans, health maintenance organizations and
other sources of reimbursement for health care costs, to reimburse all or part
of the cost of the procedure in which the medical device is being used. Such
third-party payors have become increasingly sensitive to cost containment in
recent years and place a high degree of scrutiny on coverage and payment
decisions for new technologies and procedures.
   
  Hearing aids, which are the subject of 510(k) and do not involve surgery,
are generally not reimbursed, although a modest reimbursement is provided
under certain insurance plans. Traditionally, hearing aid users have paid for
these devices directly. For cochlear implants, however, that are
technologically advanced and FDA-approved through the PMA process for the
treatment of profound hearing impairment, a reimbursement is available for the
device, the audiological testing, and the surgery. Similarly, reimbursement is
available for ossicular replacement prostheses that are FDA-approved for the
treatment of conductive hearing impairment. The Company anticipates that, as
surgically implanted devices that require FDA PMA approval, the Company's
products may also be the subject of reimbursement in the future. During
clinical trials, the Company does not anticipate that there will be any
reimbursement for the Vibrant soundbridge implant or procedure.     
 
  The Company's strategy is to pursue reimbursement for the Vibrant
soundbridge, once a PMA is approved by the FDA, based on surgeon endorsement
and demonstration of improved quality of life for specific patient groups.
Quality of life issues are included in the Company's clinical trial to provide
data in support of this reimbursement strategy. There can be no assurance that
the Company will be able to demonstrate improvement in quality of life or that
reimbursement will ever be available for the Company's products.
 
                                      44
<PAGE>
 
  Certain third-party payors are moving toward a managed care system in which
they contract to provide comprehensive health care for a fixed cost per
person. The fixed cost per person established by these third-party payors may
be independent of the hospital's cost incurred for the specific case and the
specific devices used. Medicare and other third-party payors are increasingly
scrutinizing whether to cover new products and the level of reimbursement for
covered products. Because the Company's hearing prostheses are currently under
development and have not received FDA clearance or approval, uncertainty
exists regarding the availability of third-party reimbursement for procedures
that would use the Company's soundbridges. Failure by physicians, hospitals
and other potential users of the Company's soundbridges to obtain sufficient
reimbursement from third-party payors for the procedures in which the
Company's soundbridges are intended to be used could have a material adverse
effect on the Company's business, financial condition and results of
operations.
 
  Third-party payors that do not use prospectively fixed payments increasingly
use other cost-containment processes or require various outcomes data that may
pose administrative hurdles to the use of the Company's soundbridges. In
addition, third-party payors may deny reimbursement if they determine that the
device used in a procedure is unnecessary, inappropriate, experimental, used
for a non-approved indication or is not cost-effective. Potential purchasers
must determine that the clinical benefits of the Company's products justify
the additional cost or the additional effort required to obtain prior
authorization or coverage and the uncertainty of actually obtaining such
authorization or coverage.
 
  If the Company obtains the necessary foreign regulatory approvals, market
acceptance of the Company's products and products currently under development
in international markets would be dependent, in part, upon the availability of
reimbursement within prevailing health care payment systems. Reimbursement and
health care payment systems in international markets vary significantly by
country, and include both government sponsored health care and private
insurance. There can be no assurance that any international reimbursement
approvals will be obtained in a timely manner, if at all. Failure to receive
international reimbursement approvals could have a material adverse effect on
market acceptance of the Company's products in the international markets in
which such approvals are sought.
 
  The Company believes that in the future reimbursement will be subject to
increased restrictions both in the United States and in international markets.
The Company believes that the overall escalating cost of medical products and
services will continue to lead to increased pressures on the health care
industry, both foreign and domestic, to reduce the cost of products and
services, including the Company's products and products currently under
development. There can be no assurance in either United States or
international markets that third-party reimbursement and coverage will be
available or adequate, that future legislation, regulation or reimbursement
policies of third-party payors will not otherwise adversely affect the demand
for the Company's products or products currently under development or its
ability to sell its products on a profitable basis. The unavailability of
third-party payor coverage or the inadequacy of reimbursement could have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
PRODUCT LIABILITY
   
  The Company's business involves the inherent risk of product liability
claims. The Company maintains limited product liability insurance at coverage
levels which the Company believes to be commercially reasonable and adequate
given the Company's current operations. However, there can be no assurance
that such insurance will continue to be available on commercially reasonable
terms, or at all, or that such insurance will be adequate to cover liabilities
that may arise. Any claims that are brought against the Company could, if
successful, have an adverse effect on the Company's business, financial
condition and results of operations.

EMPLOYEES
   
  At December 31, 1997, the Company had 45 employees. Of these employees, 23
were in research and development, including regulatory and clinical affairs,
16 were in manufacturing and quality assurance and six were in administration,
sales and marketing. None of the Company's employees is covered by a
collective bargaining agreement and the Company believes that it maintains
good relations with its employees.     
 
FACILITIES
   
  The Company's principal administrative, manufacturing and research and
development facility occupies approximately 11,500 square feet in San Jose,
California, pursuant to a lease that expires in August 1998. The Company has
signed a lease on a facility of approximately 30,500 square feet in San Jose,
California that expires in December 2002. The Company is in the process of
making leasehold improvements in this building and expects to occupy the
facility in the first quarter of 1998. This new facility, which will replace
the current facility, is necessary for the establishment of commercial-scale
manufacturing, and will house all of the Company's U.S. operations. The
Company has established an office in Basel, Switzerland for the headquarters
of its European sales and marketing organization.

BOARD COMPOSITION
 
  The Company currently has authorized six directors. In accordance with the
terms of the Company's Restated Certificate of Incorporation, to be filed
after the closing of this offering, the terms of office of the Board of
Directors will be divided into three classes: Class I, whose term will expire
at the annual meeting of stockholders to be held in 1999; Class II, whose term
will expire at the annual meeting of stockholders to be held in 2000; and
Class III, whose term will expire at the annual meeting of stockholders to be
held in 2001. The Class I directors will be Terry Gould and Geoffrey R. Ball,
the Class II directors will be Petri T. Vainio and Michael J. Levinthal and
the Class III directors will be B.J. Cassin and Harry S. Robbins. At each
annual meeting of stockholders after the initial classification of the Board
of Directors, the successors to directors whose term will then expire will be
elected to serve from the time of election and qualification until the third
annual meeting following such election. In addition, the Company's Restated
Certificate of Incorporation provides that the authorized number of directors
may be changed only by resolution of the Board of Directors. Any additional
directorships resulting from an increase in the number of directors will be
distributed among the three classes so that, as nearly as possible, each class
will consist of one-third of the directors. This classification of the Board
of Directors may have the effect of delaying or preventing changes in control
or management of the Company.
 
  Each officer is elected by and serves at the discretion of the Board of
Directors. Each of the Company's officers, directors and key employees, other
than nonemployee directors, devote substantially full time to the affairs of
the Company. The Company's nonemployee directors devote such time to the
affairs of the Company as is necessary to discharge their duties. There are no
family relationships among any of the directors, officers or key employees of
the Company.
 
BOARD COMMITTEES
 
  The Audit Committee of the Board of Directors reviews the internal
accounting procedures of the Company and consults with and reviews the
services provided by the Company's independent accountants. The members of the
Audit Committee are B.J. Cassin, Michael J. Levinthal and Petri T. Vainio. The
Compensation Committee of the Board of Directors reviews and recommends to the
Board the compensation and benefits of all officers of the Company and
establishes and reviews general policies relating to compensation and benefits
of employees of the Company. The members of the Compensation Committee are
B.J. Cassin, Michael J. Levinthal and Petri T. Vainio.
 
DIRECTOR COMPENSATION
 
  The Company does not compensate the directors for the services they provide
as directors other than reasonable expenses in connection with attendance at
Board Meetings, for which directors may receive reimbursement. However, in the
past, stock options have been granted to individuals who serve as directors.

(1) Each of the options listed above vests as follows: The options were
    immediately exercisable, conditioned upon the optionee entering into a
    restricted stock purchase agreement with the Company with respect to any
    unvested shares. The options vest or are released from the repurchase
    option at the rate of one forty-eighth ( 1/48) at the end of each full
    month beginning on the grant date for each option.     
   
(2) Based on an aggregate of 395,681 options granted by the Company in the
    year ended December 31, 1997 to employees of and consultants to the
    Company, including the Named Executive Officers.     
   
(3) The exercise price per share of each option was equal to the fair market
    value of the Common Stock on the date of grant as determined by the Board
    of Directors.     
   
(4) The 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the Securities and Exchange Commission. There can
    be no assurance provided to any executive officer or any other holder of
    the Company's securities that the actual stock price appreciation over the
    option term will be at the assumed 5% or 10% levels or at any other
    defined level. Unless the market price of the Common Stock appreciates
    over the option term, no value will be realized from the option grants
    made to the executive officers. The potential realizable value is
    calculated by assuming that the initial public offering price of $12.00
    per share appreciates at the indicated rate for the entire term of the
    option and that the option is exercised at the exercise price and sold on
    the last day of its term at the appreciated price.

(1) Shares and options held by the above Named Executive Officers are subject
    to vesting over a four year period.
(2) Based on the assumed initial public offering price of $12.00 per share,
    minus the per share exercise price, multiplied by the number of shares
    underlying the option.
 
OPTION VESTING AGREEMENTS
   
  The Company has entered into an option vesting agreement with each of its
officers with whom it has entered into a stock option agreement, to provide
for accelerated vesting of all shares subject to such option (i) 12 months
after a change in control or (ii) in the event such officer is involuntarily
terminated within the 12 month period following a change in control. For
purposes of the option vesting agreement, "change in control" is defined as
(i) the closing of a merger, reorganization, sale of shares or sale of
substantially all of the assets of the Company in which the stockholders of
the Company immediately prior to the closing of the transaction own less than
50% of the voting power of the surviving or controlling entity (or its parent)
immediately after the transaction, or (ii) the date of the approval by the
stockholders of the Company of a plan of complete liquidation of the Company.
The following officers were granted the following options to purchase shares
of Common Stock through December 31, 1997, which options vest over four years:
R. Michael Crompton (109,009 shares); Peter Hertzmann (94,474 shares); Bob H.
Katz (188,950 shares); Alfred G. Merriweather (112,643 shares); Patrick J.
Rimroth (109,008 shares); and Harry S. Robbins (250,600 shares).     
 
INCENTIVE STOCK PLANS
   
  1994 Option Plan. The 1994 Option Plan was adopted by the Board of Directors
and approved by the stockholders in July 1994. As of December 31, 1997,
566,531 shares were subject to outstanding options at exercise prices ranging
from $0.14 to $8.81 per share and 403,159 shares were available for future
grant under the 1994 Option Plan. The purposes of the 1994 Option Plan are to
attract and retain qualified personnel, to provide additional incentives to
employees, officers and consultants of the Company and to promote the success
of the Company's business. Pursuant to the 1994 Option Plan, the Company may
grant options which qualify as incentive stock options under Section 422 of
the Internal Revenue Code of 1986, as amended (the "Code"), to employees
(including officers and directors who are employees) and nonqualified stock
options to employees, officers, directors and consultants.     
 
 
                                      53
<PAGE>
 
  The Compensation Committee is authorized to administer the 1994 Option Plan,
including the selection of the employees, directors and consultants of the
Company to whom stock options may be granted and the interpretation and
adoption of rules for the operation of the 1994 Option Plan. Options granted
under the 1994 Option Plan generally vest incrementally over a four-year
period. However, the vesting schedule is subject to modification by the Board
of Directors. The maximum term for options granted under the 1994 Option Plan
is ten years, except that, if at the time of the grant the optionee possesses
more than 10% of the combined voting power of the Company (a "10%
Stockholder"), the maximum term of an option is five years. The exercise price
of incentive stock options granted to a 10% stockholder must be at least 110%
of the fair market value of the stock subject to the option on the date of
grant. Except pursuant to a merger or other corporate transaction, the
exercise price of nonqualified stock options granted under the 1994 Option
Plan must be at least 100% of the fair market value of the stock subject to
the option on the date of grant. Payment of the exercise price may be made by
cash, check, promissory note, other shares of Common Stock of the Company
owned by the optionee for a sufficient period, cancellation of indebtedness
pursuant to a cashless exercise program, if one is implemented by the Company,
and any other method permitted by law. The 1994 Option Plan may be amended at
any time by the Board of Directors, although certain amendments would require
stockholder approval. The 1994 Option Plan will terminate in 2004, unless
earlier terminated by the Board of Directors.
   
  Employee Stock Purchase Plan. The Company's Employee Stock Purchase Plan
(the "Purchase Plan") was adopted by the Company's Board of Directors in
November 1997 and approved by the stockholders in January 1998. The Purchase
Plan is intended to qualify under Section 423 of the Code. The Company has
reserved 75,000 shares of Common Stock for issuance under the Purchase Plan.
Under the Purchase Plan, an eligible employee may purchase shares of Common
Stock from the Company through payroll deductions of up to 10% of his or her
compensation, at a price per share equal to 85% of the lower of (i) the fair
market value of the Company's Common Stock on the first day of an offering
period under the Purchase Plan or (ii) the fair market value of the Common
Stock on the last day of a purchase period. Each offering period will last for
24 months and will commence the first day on which the national stock
exchanges and The Nasdaq Stock Market are open for trading on or after May 1
and November 1 of each year. The first offering period will begin upon the
effective date of this offering and will end on October 31, 1998. Any employee
who is customarily employed for at least 20 hours per week and more than five
months per calendar year is eligible to participate in the Purchase Plan. No
shares have been purchased under the Purchase Plan to date.     
 
EMPLOYEE RETIREMENT PLANS
 
  In April 1996, the Company implemented a Retirement Savings and Investment
Plan that is intended to qualify under Section 401(k) of the Code (the "401(k)
Plan") covering all of the Company's employees who have attained age 18. An
employee may elect to defer, in the form of contributions to the 401(k) Plan
on his or her behalf, up to 20% of the total compensation that would otherwise
be paid to the employee, not to exceed the amount allowed by applicable
Internal Revenue Service guidelines. The Company may in its discretion make
matching contributions to the 401(k) Plan, but has not yet done so.
Contributions by employees or by the Company to the 401(k) Plan, and income
earned on plan contributions, are not taxable to employees until withdrawn
from the 401(k) Plan. Contributions by the Company are deductible by the
Company when made.

license (exclusively or nonexclusively) to any third party, any of certain
defined intellectual property rights that are or may be used or may have
application in the field of implantable and semi-implantable hearing aid
devices or (ii) transfer or dispose of all or substantially all of the assets
or voting securities of the Company to any third party until it provides JJDC
the opportunity to consummate a similar transaction. JJDC's first negotiation
rights survive for a period of 18 months from the date of the June 1997 Series
D Preferred Stock financing or 12 months from the effective date of the
Company's registration statement relating to its initial public offering,
whichever first occurs. Notwithstanding the foregoing, JJDC's first
negotiation rights terminate in the event that JJDC, either directly or
through an affiliate, does not participate as an investor in this offering.
 
  On March 14, 1997, the Company entered into an assignment agreement with
VibRx, Inc., a Delaware corporation ("VibRx"), whereby the Company assigned to
VibRx all of the right, title and interest of the Company in and to any and
all existing inventions, original works of authorship, developments,
improvements, trade secrets, patents and patent applications relating to (i)
an apparatus and method for sonically enhanced drug delivery and (ii) an
apparatus and method for
 
                                      55
<PAGE>
 
   
sonically enhanced drug delivery with micro electromechanical machining. Harry
S. Robbins, the Company's President, is the President, sole director and sole
stockholder of VibRx. Independent and disinterested members of the Company's
Board of Directors negotiated the terms of such transfer with Mr. Robbins, who
negotiated on behalf of VibRx. Such terms provide that immediately prior to
the closing of an initial financing in which VibRx receives at least $500,000,
VibRx will issue to Symphonix that number of shares of common stock equal to
20% of the then outstanding capital stock of VibRx (including reserved
shares).

following aggregate amounts (including accrued interest): Bob H. Katz
($92,882), Alfred G. Merriweather ($94,473), Patrick J. Rimroth ($99,764) and

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company will consist of 50,000,000
shares of Common Stock and 5,000,000 shares of Preferred Stock after giving
effect to the conversion of all outstanding shares of Preferred Stock into
Common Stock and the restatement of the Company's Certificate of Incorporation
after the closing of this offering.
 
  The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of the Company's Restated
Certificate of Incorporation which is included as an exhibit to the
Registration Statement of which this Prospectus is a part, and by the
provisions of applicable law.
 
COMMON STOCK
   
  As of December 31, 1997, there were 9,466,742 shares of Common Stock
outstanding which were held of record by 101 stockholders, on a pro forma
basis to reflect the conversion of all outstanding shares of Preferred Stock
which will occur upon the closing of this offering.     
 
  The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. 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 Board of Directors out of funds legally available for
that purpose. See "Dividend Policy." In the event of a liquidation,
dissolution or winding up of the Company, the 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. All outstanding shares of Common Stock are
fully paid and non-assessable, and the shares of Common Stock to be issued
upon the closing of this offering will be fully paid and non-assessable.
 
PREFERRED STOCK
   
  After the closing of this offering, the Company will be authorized to issue
5,000,000 shares of undesignated Preferred Stock, none of which will be
outstanding. The Board of Directors will have the authority, without further
action by the stockholders, to issue the undesignated Preferred Stock in one
or more series, to fix the rights, preferences, privileges and restrictions
granted to or imposed upon any wholly unissued shares of undesignated
Preferred Stock and to fix the number of shares constituting any series and
the designation of such series.     
 
  The issuance of Preferred Stock may have the effect of delaying, deferring
or preventing a change in control of the Company without further action by the
stockholders, 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.
 
WARRANTS
   
  As of December 31, 1997, the Company had outstanding a warrant to purchase
26,889 shares of Common Stock at $1.38 per share expiring in October 2004 and
two warrants to purchase an aggregate of 6,722 shares of Common Stock at $5.50
per share expiring in October 2004. The shares underlying these warrants are
entitled to registration rights. See "--Registration Rights of Certain
Holders."     
 
                                      59
<PAGE>
 
REGISTRATION RIGHTS OF CERTAIN HOLDERS
   
  The holders of 6,682,078 shares of Common Stock and warrants to purchase
33,611 shares of Common Stock (the "Registrable Securities") or their
transferees are entitled to certain rights with respect to the registration of
such shares under the Securities Act. These rights are provided under the
terms of an agreement between the Company and the holders of Registrable
Securities. Subject to certain limitations in the agreement, the holders of at
least a majority of the Registrable Securities may require, on two occasions
beginning three months after the date of this Prospectus, that the Company use
its best efforts to register the Registrable Securities for public resale. If
the Company registers any of its Common Stock either for its own account or
for the account of other security holders, the holders of Registrable
Securities are entitled to include their shares of Common Stock in the
registration, subject to the ability of the underwriters to limit the number
of shares included in the offering. The holders of at least 20% of the
Registrable Securities may also require the Company to register all or a
portion of their Registrable Securities on Form S-3 when use of such form
becomes available to the Company, provided, among other limitations, that the
proposed aggregate selling price (net of any underwriters' discounts or
commissions) is at least $1.0 million. All registration expenses must be borne
by the Company and all selling expenses relating to Registrable Securities
must be borne by the holders of the securities being registered.     
 
CERTAIN PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION AND BYLAWS
 
  Certain provisions of the Company's Restated Certificate of Incorporation
and Bylaws to be effective upon completion of this offering may have the
effect of preventing, discouraging or delaying a change in the control of the
Company and may maintain the incumbency of the Board of Directors and
management. The authorization of undesignated Preferred Stock makes it
possible for the Board of Directors to issue Preferred Stock with voting or
other rights or preferences that could impede the success of any attempt to
change control of the Company. In addition, the Company's Bylaws limit the
ability of stockholders of the Company to raise matters at a meeting of
stockholders without giving advance notice.
   
  The Restated Certificate of Incorporation provides that stockholder action
can be taken only at an annual or special meeting of stockholders and cannot
be taken by written consent in lieu of a meeting. The Restated Certificate of
Incorporation and the Bylaws provide that, except as otherwise required by
law, special meetings of the stockholders can only be called pursuant to a
resolution adopted by a majority of the Board of Directors, by the Chairman of
the Board or by the President of the Company.     
   
  The Bylaws establish an advance notice procedure for stockholder proposals
to be brought before an annual meeting of stockholders of the Company,
including proposed nominations of persons for election to the Board.
Stockholders at an annual meeting may only consider proposals or nominations
specified in the notice of meeting or brought before the meeting by or at the
direction of the Board or by a stockholder who was a stockholder of record on
the record date for the meeting, who is entitled to vote at the meeting and
who has given to the Company's Secretary timely written notice, in proper
form, of the stockholder's intention to bring that business before the
meeting. Although the Bylaws do not give the Board the power to approve or
disapprove stockholder nominations of candidates or proposals regarding other
business to be conducted at a special or annual meeting, the Bylaws may have
the effect of precluding the conduct of certain business at a meeting if the
proper procedures are not followed or may discourage or defer a potential
acquiror from conducting a solicitation of proxies to elect its own slate of
directors or otherwise attempting to obtain control of the Company.

CERTAIN PROVISIONS OF DELAWARE LAW
   
  Following the consummation of the offering, the Company will be subject to
the "Business Combination" provisions of the Delaware General Corporation Law.
In general, such provisions prohibit a publicly held Delaware corporation form
engaging in various "business combination" transactions with any "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an "interested stockholder," unless (i) the
transaction is approved by the Board of Directors prior to the date the
interested stockholder obtained such status, (ii) upon consummation of the
transaction which resulted in the stockholder becoming an "interested
stockholder," the "interested stockholder" owned at least 85% of the voting
stock of the corporation outstanding excluding those shares owned by (a)
persons who are directors and also officers and (b) 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) on or subsequent to such date the "business
combination" is approved by the board of directors and authorized at an annual
or special meeting of stockholders by the affirmative vote of at least 66 2/3%
of the outstanding voting stock which is not owned by the "interested
stockholder." A "business combination" is defined to include mergers, asset
sales and other transactions resulting in a financial benefit to a
stockholder. In general, an "interested stockholder" is a person who, together
with affiliates and associates, owns (or within three years, did own) 15% or
more of a corporation's voting stock. The statute could prohibit or delay
mergers or other takeover or change in control attempts with respect to the
Company and, accordingly, may discourage attempts to acquire the Company.     
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is BankBoston, N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no market for the Common Stock of the
Company. Future sales of substantial amounts of Common Stock in the public
market could materially and adversely affect market prices prevailing from
time to time. Sales of substantial amounts of Common Stock of the Company in
the public market after the restrictions lapse could materially and adversely
affect the prevailing market price and the ability of the Company to raise
equity capital in the future.
   
  Upon the completion of this offering, the Company will have 11,766,742
shares of Common Stock outstanding, assuming no exercise of options after
December 31, 1997. Of these shares, all of the 2,300,000 shares sold in this
offering will be freely tradeable without restriction under the Securities
Act, unless held by "affiliates" of the Company, as that term is defined in
Rule 144 under the Securities Act. The remaining 9,466,742 shares of Common
Stock held by existing stockholders were issued and sold by the Company in
reliance on exemptions from the registration requirements of the Securities
Act. These shares may be sold in the public market only if registered, or
pursuant to an exemption from registration such as Rule 144, 144(k) or 701
under the Securities Act. Such restricted shares will be available for sale in
the public market as follows: (i) no shares will be eligible for immediate
sale on the date of this Prospectus and (ii) approximately 9,778,368
additional shares (including approximately 311,615 shares subject to
outstanding vested options and outstanding warrants) will be available for
sale 180 days after the date of this Prospectus upon expiration of the Lock-up
Agreements, subject to certain volume and other limitations under Rule 144.
The Company and its directors, executive officers and all of its stockholders
have entered into the Lock-up Agreements, under which they have agreed not to
offer, sell, contract to sell, grant any option to purchase or otherwise
dispose of, or agree to dispose of, directly or indirectly, any shares of
Common Stock or options, rights or warrants to acquire shares of Common Stock,
or securities exchangeable for or convertible into shares of Common Stock,
owned by them for a period of 180 days following the day on which the
Registration Statement becomes effective (the "Effective Date"), without the
prior written consent of Cowen & Company or the Company, as the case may be,
except that, without such consent, the Company may issue Common Stock and
grant options pursuant to the 1994 Option Plan and issue Common Stock pursuant
to the exercise of outstanding warrants, and the current stockholders of the
Company who are not executive officers or directors of the Company may sell
Common Stock acquired in the offering or in the open market. The Company has
agreed not to release any stockholders from the terms of the Lock-up
Agreements with the Company. Cowen & Company may, in its sole discretion and
at any time without notice, release all or a portion of the shares subject to
Lock-up Agreements.     
   
  As of December 31, 1997, 566,531 shares were subject to outstanding options.
All of these shares are subject to the Lock-up Agreements. In addition,
6,719,689 of the shares outstanding immediately following the completion of
this offering (including up to 33,611 shares of Common Stock subject to
outstanding warrants) will be entitled to registration rights with respect to
such shares upon the release of the Lock-up Agreements. The number of shares
sold in the public market could increase if such rights are exercised.     
   
  In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least
one year (including the holding period of any prior owner, except an
affiliate) is entitled to sell in "broker's transactions" or to market makers,
within any three-month period commencing 90 days after the date of this
Prospectus, a number of shares that does not exceed the greater of (i) one
percent of the number of shares of Common Stock then outstanding
(approximately 118,000 shares immediately after this offering) or (ii) the
average weekly trading volume of the Common Stock during the four calendar
weeks preceding the required filing of a Form 144 with respect to such sale.
Sales under Rule 144 are generally subject to certain manner of sale
provisions and notice requirements and to the availability of current public
    
                                      62
<PAGE>
 
information about the Company. Under Rule 144(k), a person who is not deemed
to have been an affiliate of the Company at any time during the 90 days
preceding a sale, and who has beneficially owned the shares proposed to be
sold for at least two years (including the holding period of any prior owner,
except an affiliate), is entitled to sell such shares without having to comply
with the manner
of sale, public information, volume limitation or notice provisions of Rule
144. Under Rule 701 promulgated under the Securities Act, persons who purchase
shares upon exercise of options granted prior to the effective date of this
offering are entitled to sell such shares 90 days after the effective date of
this offering in reliance on Rule 144, without having to comply with the
holding period requirements of Rule 144 and, in the case of non-affiliates,
without having to comply with the public information, volume limitation or
notice provisions of Rule 144.

  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent, including the absence of any
material adverse change in the Company's business and the receipt of certain
certificates, opinions and letters from the Company and its counsel and
independent auditors. The nature of the Underwriters' obligations is such that
they are committed to purchase all shares of Common Stock offered hereby if
any of such shares are purchased.
 
  The Underwriters propose to offer the shares of Common Stock directly to the
public at the initial public offering price set forth on the cover page of
this Prospectus and to certain dealers at such price less a concession not in
excess of $     per share. The Underwriters may allow and such dealers may re-
allow a concession not in excess of $    per share to certain other dealers.
The Underwriters have informed the Company that they do not intend to confirm
sales to any accounts over which they exercise discretionary authority. After
the initial public offering of the shares, the offering price and other
selling terms may from time to time be varied by the Underwriters.
 
  The Company has granted to the Underwriters an option, exercisable no later
than 30 days after the Effective Date, to purchase up to 345,000 additional
shares of Common Stock at the initial public offering price, less the
underwriting discounts and commissions, set forth on the cover page of this
Prospectus, to cover over-allotments, if any. If the Underwriters exercise
such over-allotment option, the Underwriters have severally agreed, subject to
certain conditions, to purchase approximately the same percentage thereof that
the number of shares of Common Stock to be purchased by each of them shown in
the foregoing table bears to the total number of shares of Common Stock
offered hereby. The Underwriters may exercise such option only to cover over-
allotments made in connection with the sale of shares of Common Stock offered
hereby.
   
  The Company and its directors, executive officers and all of its
stockholders (holding in the aggregate approximately 9,466,742 shares of
Common Stock) have agreed with the Company or Cowen & Company that they will
not, without the prior written consent of the Company or Cowen & Company, as
the case may be, offer, sell, contract to sell, grant any option to purchase
or otherwise dispose of or otherwise agree to dispose of, directly or
indirectly any shares of Common Stock,

options, rights or warrants to acquire shares of Common Stock, or securities
exchangeable for or convertible into shares of Common Stock, owned by them for
a period of 180 days following the day on which the Registration Statement
becomes effective, except that, without such consent, the Company may issue
Common Stock and grant options pursuant to the 1994 Option Plan and issue
Common Stock pursuant to the exercise of outstanding warrants, and the current
stockholders of the Company who are not executive officers or directors of the
Company may sell Common Stock acquired in the offering or in the open market.
The Company has agreed not to release any stockholders from the terms of Lock-
up Agreements with the Company. See "Shares Eligible for Future Sale." In
addition, the Company has agreed that it will not, without the prior written
consent of Cowen & Company, offer, sell or otherwise dispose of any shares of
Common Stock options, rights or warrants to acquire shares of Common Stock, or
securities exchangeable for or convertible into shares of Common Stock during
such 180-day period except in certain limited circumstances.     
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, and to contribute
to payments the Underwriters may be required to make in respect thereof.
 
  Prior to this offering, there has been no public market for the Common
Stock. The initial public offering price for the Common Stock has been
determined by negotiation among the Company and the Representatives. Among the
factors considered in determining the initial public offering price were
prevailing market and economic conditions, market valuations of other
companies engaged in activities similar to the Company, estimates of the
business potential and prospects of the Company, the present state of the
Company's business operations, the Company's management and other factors
deemed relevant.
 
  The Representatives have advised the Company that certain persons
participating in this offering may engage in transactions, including
stabilizing bids, syndicate covering transactions or the imposition of penalty
bids which may have the effect of stabilizing or maintaining the market price
of the Common Stock at a level above that which might otherwise prevail in the
open market. A "stabilizing bid" is a bid for or the purchase of the Common
Stock on behalf of the Underwriters for the purpose of fixing or maintaining
the price of the Common Stock. A "syndicate covering transaction" is the bid
or the purchase of the Common Stock on behalf of the Underwriters to reduce a
short position incurred by the Underwriters in connection with this offering.
A "penalty bid" is an arrangement permitting the Representatives to reclaim
the selling concession otherwise accruing to an Underwriter or syndicate
member in connection with the offering if the Common Stock originally sold by
such Underwriter or syndicate member is purchased by the Representatives in a
syndicate covering transaction and has therefore not been effectively placed
by such Underwriter or syndicate member. The Representatives have advised the
Company that such transactions may be effected on the Nasdaq National Market
or otherwise and, if commenced, may be discontinued at any time.
 
                                 LEGAL MATTERS
   
  The validity of the Common Stock offered hereby will be passed upon for the
Company by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo
Alto, California. Cooley Godward, LLP, Palo Alto, California is acting as
counsel for the Underwriters in connection with certain legal matters relating
to the shares of Common Stock offered hereby. As of December 31, 1997, a

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
   
Symphonix Devices, Inc. and Subsidiary     
   
  We have audited the accompanying consolidated balance sheets of Symphonix
Devices, Inc. and Subsidiary (a company in the development stage) as of
December 31, 1996 and 1997, and the related consolidated statements of
operations, stockholders' equity and cash flows for the period from May 17,
1994 (date of inception) to December 31, 1994, for each of the three years in
the period ended December 31, 1997, and for the cumulative period from May 17,
1994 (date of inception) to December 31, 1997. 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 audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
   
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Symphonix
Devices, Inc. and Subsidiary (a company in the development stage) as of
December 31, 1996 and 1997, and the results of its operations and its cash
flows for the period from May 17, 1994 (date of inception) to December 31,
1994, for each of the three years in the period ended December 31, 1997, and
for the cumulative period from May 17, 1994 (date of inception) to December
31, 1997, in conformity with generally accepted accounting principles.

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS     
 
1. FORMATION AND BUSINESS OF THE COMPANY:
   
  Symphonix Devices, Inc. and Subsidiary (a company in the development stage,
referred to hereafter as the "Company") was incorporated on May 17, 1994 to
develop and manufacture implantable and semi-implantable hearing devices.
Since its inception, the Company has been primarily engaged in developing its
initial product technology, raising capital and recruiting personnel.     
 
  In the course of its development activities, the Company has sustained
losses and expects such losses to continue through at least 1999. The Company
plans to continue its operations with proceeds from the sale of capital stock,
such as the initial public offering contemplated by the Prospectus, of which
these financial statements are a part, and with revenues from product sales.
If the offering contemplated herein is not consummated, the Company will have
to seek other sources of capital or adjust its operating plans.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
   
 Basis of Consolidation     
   
  The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary. All significant intercompany accounts and
transactions have been eliminated.     
 
 Cash and Cash Equivalents:
 
  The Company considers all highly liquid investments purchased with original
maturities of three months or less to be cash equivalents.
 
 Short-Term Investments:
 
  All short-term investments are classified as available-for-sale and
therefore are carried at fair market value. Unrealized gains and losses on
such securities, when material, are reported as a separate component of
stockholders' equity. Realized gains and losses on sales of all such
securities are reported in earnings and computed using the specific
identification cost method.
 
 Property and Equipment:
 
  Property and equipment are stated at cost and are depreciated on a straight-
line basis over the shorter of the estimated useful lives of three to five
years or the length of the lease for leasehold improvements and assets
acquired under capital leases.
 
 Research and Development:
 
  Research and development costs are charged to operations as incurred.
 
 Concentration of Credit Risk and Other Risks and Uncertainties:
   
  The Company's cash, cash equivalents, and short-term investments are
primarily maintained at two financial institutions.     
 
  The Company's products require approvals from the Food and Drug
Administration and international regulatory agencies prior to commercialized
sales. There can be no assurance that the Company's products will receive any
of these required approvals. If the Company was denied such approval or such
approvals were delayed, it would have a materially adverse impact on the
Company.

                  SYMPHONIX DEVICES, INC. AND SUBSIDIARY

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)     
 
 
 Income Taxes:
 
  The Company accounts for income taxes under the liability method, whereby
deferred tax assets and liabilities are determined based on the difference
between the financial statement and tax bases of assets and liabilities using
enacted tax rates in effect for the year in which the differences are expected
to affect taxable income. Valuation allowances are established when necessary
to reduce deferred tax assets to the amounts expected to be realized.
 
 Use of Estimates:
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.
   
 Foreign currency translation:     
   
  The Company's international subsidiary uses its local currency as its
functional currency. Assets and liabilities are translated at exchange rates
in effect at the balance sheet date and income and expense accounts at average
exchange rates during the year. Resulting translation adjustments are recorded
directly to a separate component of stockholders' equity.     
   
 Computation of Historical Net Loss Per Common Share and Per Common Share-
Assuming Dilution:     
   
  The Company adopted Financial Accounting Standards Board No. 128 "Earnings
Per Share" and accordingly all prior periods have been restated. Net loss per
common share and per common share-assuming dilution, on an historical basis,
are computed using the weighted average number of shares of Common Stock
outstanding. Common equivalent shares from stock options and preferred stock
are excluded from the computation of net loss per common share-assuming
dilution as their effect is antidilutive. However, pursuant to the Securities
and Exchange Commission Staff Accounting Bulletin No. 83, common and common
equivalent shares issued at prices below the anticipated public offering price
during the 12 months immediately preceding the initial filing date,
aggregating 851,441 common equivalent shares, have been included in both
calculations as if they were outstanding for all periods presented (using the
treasury stock method and the anticipated initial public offering price).     
       
       
 Recent Accounting Pronouncements:
       
  In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income". SFAS No. 130 establishes standards for the reporting and display of
comprehensive income and its components in a full set of general purpose
financial statements. Comprehensive income is defined as the change in equity
of a business enterprise during a period, resulting from transactions and
other events and circumstances from nonowner sources. The impact of adopting
SFAS No. 130, which is effective for the Company in 1998, has not been
determined.
 
  In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information". SFAS No. 131 requires publicly-held
companies to report financial and other information about key revenue-
producing segments of the entity for which such information is available and
is utilized by the chief operating decision maker. Specific information to be
reported for individual segments includes profit or loss, certain revenue and
expense items and total assets. A reconciliation of segment financial
information to amounts reported in the financial statements would be provided.
SFAS No. 131 is effective for the Company in 1998. The Company operates in one
business segment; namely, the design, manufacture, and sale of implantable and
semi-implantable hearing management devices.

in the preferred stock conversion ratios. All common stock and per share
amounts in these financial statements have been adjusted retroactively to give
effect to the split. In addition, the Company's Board of Directors approved an
Amended and Restated Certificate of Incorporation which eliminates the
existing convertible preferred stock and changes the number of authorized
preferred stock to 5,000,000 shares, $0.001 par value, and increases the
shares of common stock authorized to 50,000,000 shares, which Certificate is
to be filed following the effectiveness of the initial public offering.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)     
 
 
 Liquidation:
 
  In the event of any liquidation, dissolution or winding up of the Company,
either voluntary or involuntary, the holders of Series A, Series B, Series C
and Series D preferred stock are entitled to receive, prior and in preference
to any distribution of any of the assets or surplus funds of the Company to
the holders of common stock, an amount per share equal to the sum of $1.00,
$4.00, $5.35 and $8.00 respectively, for each outstanding Series A, Series B,
Series C and Series D preferred stock (as adjusted for any stock dividends,
combinations or splits) plus any declared but unpaid dividends on such shares.
If upon the occurrence of such event, the assets and funds distributed among
the holders of the preferred stock are insufficient to permit the payment to
such holders of the full aforesaid preferential amounts, then, the entire
assets and funds of the Company legally available for distribution are to be
distributed first ratably among the holders of the Series C and Series D
preferred stock in proportion to the full preferential amount each such holder
is otherwise entitled to receive. Then, such assets and funds shall be
distributed ratably among the holders of Series A and Series B preferred stock
in proportion to the full preferential amount each such holder is otherwise
entitled to receive.
 
  After payment has been made to the holders of Series A, Series B, Series C
and Series D preferred stock, any remaining assets and funds are to be
distributed among the holders of common stock pro rata based on the number of
common stock held by each stockholder.
 
 Mergers:
 
  A merger, reorganization, or sale of all or substantially all of the assets
of the Company, in which the existing stockholders of the Company prior to the
transaction possess less than 50% of the voting power of the surviving entity
(or its parent) immediately after the transaction, shall be deemed to be a
liquidation, dissolution or winding up of the Company.
 
 Voting:
 
  Each share of preferred stock is entitled to voting rights equal to the
number of common shares into which each preferred share could be converted
into at the record date for a vote or consent of stockholders, except as
otherwise required by law, and has voting rights and powers equal to the
voting rights and powers of the common stock.
 
 Conversion and Registration:
 
  Each share of preferred stock, at the option of the holder, is convertible
into the number of fully paid and nonassessable shares of common stock which
results from dividing the conversion price per share in effect for the
preferred stock at the time of conversion into the per share conversion value
of such stock. The initial conversion price per share and initial per share
conversion value of Series A, Series B, Series C and Series D preferred stock
is $1.38, $5.50, $7.36 and $11.01, respectively. The initial conversion price
of Series A, Series B, Series C and Series D preferred stock is subject to
adjustment from time to time, as described in the Company's Restated Articles
of Incorporation.
   
  In the event of a conversion of the Series C preferred stock in connection
with this initial public offering at a price lower than $11.70 per share of
common stock, then the Conversion Price for the Series C preferred stock shall
be reduced to $6.90. In the event of a conversion of the Series D preferred
stock in connection with this initial public offering at a price lower than
$11.00 per share of common stock, then the Conversion Price for the Series D
preferred stock shall be reduced to the initial public offering price.

         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)     
   
  Conversion is automatic at the then effective conversion rate immediately
upon the closing of a firm commitment underwritten public offering pursuant to
an effective registration statement under the Securities Act of 1933 covering
the offer and sale of common stock in which the public offering price equals
or exceeds $10.00 per share (adjusted to reflect subsequent share dividends,
share splits or recapitalization) and the aggregate proceeds raised equals or
exceeds $17,000,000. The Company has reserved 9,750,000 shares of common stock
upon conversion of the preferred stock as of December 31, 1997).     
 
 Negotiation Rights:
   
  In connection with the Series D preferred stock issuances, the Company
granted one of the investors first negotiation rights, whereby the Company
agreed not to (i) transfer, dispose of, sell, lease or license to any third
party certain defined intellectual property rights that are or may be used or
may have application in the field of implantable or semi-implantable hearing
aid devices or (ii) transfer or dispose of all or substantially all of the
assets or voting securities of the Company to any third party until it
provides that investor the opportunity to consummate a similar transaction.
The first negotiation rights survive from a period of 18 months from the date
of the Series D preferred stock agreement or 12 months from the effective date
of the Company's initial public offering, whichever first occurs. However, the
first negotiation rights will terminate if the investor, either directly or
through an affiliate, does not participate as an investor in the Company's
initial public offering.     
 
 Warrants:
 
  The Company has issued warrants in connection with obtaining its equipment
lease line of credit.
 
  The Company issued to the leasing company warrants to purchase up to 37,000
of the Company's Series A preferred stock at $1.00 per share and up to 9,250
of the Company's Series B preferred stock at $4.00 per share. The warrants to
purchase the Company's Series A and Series B preferred stock are exercisable
until October 2004.
 
 Common Stock:
   
  The Company has 2,784,664 shares of its common stock outstanding at December
31, 1997. Such shares of common stock were issued to the founders and other
key persons under purchase agreements. Under these agreements, any unvested
shares are subject to repurchase by the Company for a period of 90 days after
termination of services to the Company. Shares generally vest 1/48 per month
at the end of each full month. At December 31, 1997, approximately 632,194
shares of common stock are subject to repurchase.     
 
 Notes Receivable:
   
  In 1994, 1996 and 1997, the Company issued 1,075,581, 207,122 and 337,809
shares, respectively, of its common stock to one of the founders and other key
persons in exchange for promissory notes of $29,600, $124,400 and $359,999,
respectively. The 1994 promissory notes bear annual interest of 5.36%, payable
in the year 1999. A principal payment of $14,800 was made in 1994. The 1996
and 1997 promissory notes bear annual interest ranging from 6.36% to 6.84%,
payable in the years 2001 and 2002. The related shares are pledged as
collateral for the notes.

 1997 Employee Stock Purchase Plan     
   
  The Company's 1997 Employee Stock Purchase Plan (the "Purchase Plan") was
adopted by the Board of Directors in November 1997. A total of 75,000 shares
of common stock are reserved for issuance under the Purchase Plan. The
Purchase Plan permits eligible employees to purchase common stock through
payroll deductions, which may not exceed 10% of an employee's compensation. No
employee may purchase more than $25,000 worth of common stock in any calendar
year. The price of shares purchased under the Purchase Plan is 85% of the
price of the fair market value of the common stock at the beginning of the
offering period or the specified purchase date. The Purchase Plan will become
effective upon the closing of the Company's initial public offering.     
 
 1994 Stock Option Plan:
 
  The 1994 Stock Option Plan (the "1994 Plan") provides for grants of
incentive stock options to employees (including officers and employee
directors) and nonstatutory stock options to employees (including officers and
employee directors) and consultants of the Company. The 1994 Plan is
administered by a committee appointed by the Board of Directors which
identifies optionees and determines the terms of options granted, including
the exercise price, number of shares subject to the option and the
exercisability thereof.
 
  The terms of options granted under the 1994 Plan generally may not exceed
ten years. The term of all incentive stock options granted to an optionee who,
at the time of grant, owns stock representing more than 10% of the voting
power of all classes of stock of the Company or a parent or subsidiary of the
Company (a "Ten Percent Stockholder"), may not exceed five years, however.
Generally, options granted under the 1994 Plan vest and become exercisable
starting one year after the date of grant, with 25% of the shares subject to
the option becoming exercisable at that time and an additional 1/48th of such
shares becoming exercisable each month thereafter. Holders of options granted
under the 1994 Plan may exercise their unvested options prior to complete
vesting of shares, subject to such holder's entering a restricted stock
purchase agreement granting the Company an option to repurchase, in the event
of a termination of the optionee's employment or consulting relationship, any
unvested shares at a price per share equal to the original exercise price per
share for the option. The exercise price of incentive stock options granted
under the 1994 Plan must be at least equal to the fair market value of the
shares on the date of grant. The exercise price of nonstatutory stock options
granted under the 1994 Plan is determined by the Board of Directors. The
exercise price of any incentive stock option granted to a Ten Percent
Stockholder must equal at least 110% of the fair market value of the common
stock on the date of grant.

  The difference between the exercise price and the deemed fair market value
of the Company's common stock at the date of issue of certain stock options,
totaling $1,572,596, has been recorded as deferred compensation as a component
of stockholders' equity. Of this amount, $107,481 has been recognized as an
expense through December 31, 1997. The remaining $1,465,115 will be recognized
as an expense as the shares and options vest over a period of up to four
years.

  As of December 31, 1996, options to purchase 266,989 shares were exercisable
at an average weighted exercise price of $0.62 per share.     
   
  The Company has elected to continue to follow the provisions of APB No. 25,
"Accounting for Stock Issued to Employees," for financial reporting purposes
and has adopted the disclosure-only provisions of SFAS No. 123 ("SFAS No.
123"). Had compensation cost for the Company's stock option plans been
determined based on the fair market value at the grant date for awards in
1995, 1996 and 1997 consistent with the provisions of SFAS No. 123, the
Company's net loss and net loss per common share and per common share-assuming
dilution for 1995, 1996 and 1997 would have been increased to the pro forma

1995, 1996 and 1997; dividend yield and volatility of 0% for all periods,
weighted risk-free interest rates of 6.6%, 5.8% and 6.0% at the date of grant
and expected terms of 5.0, 5.4 and 5.0 years, respectively.

  Due to the uncertainties surrounding the realization of deferred tax assets,
the Company has provided a full valuation allowance and, therefore, no benefit
has been recognized for the net operating loss and other deferred tax assets.
       
  At December 31, 1997, the Company has $13,171,517 for federal and

                  SYMPHONIX DEVICES, INC. AND SUBSIDIARY     
                     (A COMPANY IN THE DEVELOPMENT STAGE)
            
         NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)     
 
 
  The Tax Reform Act of 1986 limits the use of net operating loss and tax
credit carryforwards in certain situations where changes occur in the stock
ownership of a company. In the event the Company has had a change in
ownership, utilization of the carryforwards could be restricted.
   
10. EMPLOYEE BENEFIT PLAN:     
   
  During 1996, the Company established a Retirement Savings and Investment
Plan (the "Plan") under which employees may defer a portion of their salary up
to the maximum allowed under IRS rules. The Company has the discretion to make
contributions to the Plan. As of December 31, 1997, no Company contributions
have been made to the Plan.     
   
11. UNAUDITED PRO FORMA INFORMATION:     
   
  Upon the closing of the Company's initial public offering, all outstanding
preferred stock will be converted automatically into common stock. The pro
forma effect of the conversion has been presented as a separate column in the
Company's balance sheet, assuming the conversion had occurred as of December
31, 1997.     
   
  Pro forma net loss per common share and per common share--assuming dilution
has been presented to depict what the net loss per common share and per common
share--assuming dilution would have been had the common stock issuable upon
the conversion of the outstanding preferred stock been outstanding during such
periods.     
   
12. RELATED PARTY TRANSACTIONS:     
 
  In February 1997, the stockholders approved the assignment of technology
relating to and including two patent applications to VibRx in consideration
for repayment of approximately $10,000 of related patent expenses and issuance
of common stock equal to 20% of all VibRx's outstanding shares at such time as
VibRx completes an initial financing with aggregate proceeds of at least
$500,000. VibRx was formed and is controlled by the Company's President and
Chief Executive Officer.
       
       
       
          
13. SUBSEQUENT EVENTS     
          
  In January 1998, the Company reincorporated in Delaware. Under the
reincorporation, each class and series of shares of the predecessor company
was exchanged for one share of identical class and series of stock of the
Delaware successor company having a par value of $0.001 per share for both
common stock and preferred stock. The accompanying consolidated financial
statements have been adjusted retroactively to give effect to the
reincorporation.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
   
  Section 145 of the Delaware General Corporation Law allows for the
indemnification of officers, directors and any corporate agents under certain
circumstances for liabilities (including reimbursement for expenses incurred)
arising under the Securities Act. The Registrant's Restated Certificate of
Incorporation to be filed after the closing of the offering to which this
Registration Statement relates (Exhibit 3.2 hereto) and the Registrant's
Bylaws (Exhibit 3.3 hereto) provide for indemnification of the Registrant's
directors, officers, employees and other agents to the extent and under the
circumstances permitted by the Delaware General Corporation Law. The
Registrant also intends to enter into agreements with its directors and
executive officers that will require the Registrant among other things to
indemnify them against certain liabilities that may arise by reason of their
status or service as directors to the fullest extent not prohibited by
Delaware law.     
 
  The Underwriting Agreement provides for indemnification by the Underwriters
of the Registrant, its directors and officers, and by the Registrant of the
Underwriters, for certain liabilities, including liabilities arising under the
Securities Act, and affords certain rights of contribution with respect
thereto.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

registration pursuant to Regulation D promulgated thereunder, and in the case

ITEM 17. UNDERTAKINGS
 
  The undersigned Registrant hereby undertakes that:
 
  (a) It will provide to the Underwriters at the closing as specified in the
Underwriting Agreement certificates in such denominations and registered in
such names as required by the Underwriters to permit prompt delivery to each
purchaser.
 
  (b) Insofar as indemnification by the Registrant for liabilities arising
under the Securities Act may be permitted to directors, officers and
controlling persons of the Registrant, 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 Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed
by the final adjudication of such issue.
 
 
                                     II-3

  (c) For purposes of determining any liability under the Securities Act, 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 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.
 
  (d) For the purpose of determining any liability under the Securities Act,
each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to
be the initial bona fide offering thereof.
 
  The undersigned Registrant hereby undertakes:
 
  (a) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
 
    (i) to include any prospectus required by Section 10(a)(3) of the
  Securities Act;
 
    (ii) to reflect in the prospectus any facts or events arising after the
  effective date of the Registration Statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in this
  Registration Statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar volume of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Commission
  pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than a 20% change in the maximum aggregate offering
  price set forth in the "Calculation of Registration Fee" table in the
  effective registration statement;
 
    (iii) to include any material information with respect to the plan of
  distribution not previously disclosed in the Registration Statement or any
  material change to such information in the Registration Statement;
 
  (b) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment 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;
 
  (c) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.

                        CERTIFICATE OF INCORPORATION OF
                            SYMPHONIX DEVICES, INC.

                                  ARTICLE I.

The name of this Corporation is Symphonix Devices, Inc. (the "Corporation").

                                  ARTICLE II.

     The address of the Corporation's registered office in the State of Delaware
is 1209 Orange Street, City of Wilmington, County of Newcastle, Delaware 19801.
The name of its registered agent at such address is The Corporation Trust
Company.

                                 ARTICLE III.

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

                                  ARTICLE IV.

     This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the corporation is authorized to issue is 29,750,000 shares.
20,000,000 shares shall be Common Stock with a par value of $0.001 per share and
9,750,000 shares shall be Preferred Stock with a par value of $0.001 per share.
Of the Preferred Stock, 5,500,000 shares shall be designated Series A Preferred
Stock, 1,500,000 shares shall be designated Series B Preferred Stock, 1,500,000
shares shall be designated Series C Preferred Stock and 1,250,000 shares shall
be designated Series D Preferred Stock.

     Immediately upon the automatic conversion of all of the outstanding shares
of Preferred Stock into Common Stock pursuant to Article V, Section 3(a)(ii) or
(iii), each outstanding 1.376 shares of Common Stock will be combined into one
share of Common Stock. No fractional shares will be issued in connection with
such reverse stock split and the number of shares issuable to each stockholder
shall be determined by rounding upwards to the next whole share on a 
certificate-by-certificate basis.
<PAGE>
 
                                  ARTICLE V.

     The rights, preferences, privileges, restrictions and other matters
relating to the shares of Preferred Stock are as follows:

     1.   Dividends.  The holders of shares of Series A Preferred Stock, Series
          ---------                                                            
B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock shall
be entitled to receive dividends, out of any assets legally available therefor,
prior and in preference to any declaration or payment of any dividend (payable
other than in Common Stock or other securities and rights convertible into or
entitling the holder thereof to receive, directly or indirectly, additional
shares of Common Stock of the Corporation) on the Common Stock of the
Corporation, at the rate of $0.10, $0.40, $0.535 and $0.80 per share per annum,
respectively, or if greater (as determined on a per annum basis and an as-
converted basis for the Preferred Stock), an amount equal to that paid on any
other outstanding shares of the Corporation whenever funds are legally available
therefor, payable when, as and if declared by the Board of Directors.  No
dividend shall be declared with respect to any series of Preferred Stock unless
a dividend is declared with respect to each series of outstanding Preferred
Stock at a rate that is no less favorable to the Series A Preferred Stock, the
Series B Preferred Stock, the Series C Preferred Stock and the Series D
Preferred Stock than $0.10, $0.40, $0.535 and $0.80 per annum for each share of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, respectively.  Such dividends shall not be cumulative.

     2.   Liquidation Preference.
          ---------------------- 

          (a)  In the event of any liquidation, dissolution or winding up of the
Corporation, either voluntary or involuntary, the holders of the Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Series D
Preferred Stock shall be entitled to receive, prior and in preference to any
distribution of any of the assets or surplus funds of the Corporation to the
holders of the Common Stock by reason of their ownership thereof, an amount per
share equal to $1.00, $4.00, $5.35 and $8.00 for each outstanding share of
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and
Series D Preferred Stock, respectively (as adjusted for any combinations,
consolidations, stock distributions or stock dividends with respect to such
shares, hereinafter "as adjusted"), plus all declared but unpaid dividends on
such shares. If upon the occurrence of such event, the assets and funds thus
distributed among the holders of the Preferred Stock shall be insufficient to
permit the payment to such holders of the full aforesaid preferential amounts,
then the entire assets and funds of the Corporation legally available for
distribution shall be distributed first ratably among the holders of Series C
Preferred Stock and Series D Preferred Stock until the holders of Series C
Preferred Stock and Series D Preferred Stock have received payment of their full
aforesaid preferential amounts; provided, however, that if the assets and funds
thus distributed among the holders of the Series C Preferred Stock and Series D
Preferred Stock shall be insufficient to permit the payment to such holders of
the full aforesaid preferential amounts, then such assets shall be distributed
among such holders of Series C Preferred Stock and Series D Preferred Stock in
proportion to the respective amounts which would be payable on such shares of
Series C Preferred Stock and Series D Preferred Stock held by them if the
aforesaid preferential 

                                      -2-
<PAGE>
 
amounts were paid in full. Then, such assets and funds shall be distributed
ratably among the holders of the Series A Preferred Stock and Series B Preferred
Stock, based upon the number of shares of Series A Preferred Stock and Series B
Preferred Stock then held, in proportion to the respective amounts which would
be payable on the shares held by them if the aforesaid preferential amounts were
paid in full.

          (b)  After the payment of the full liquidation preference set forth in
Section 2(a) above, the remaining assets of the Corporation available for
distribution to shareholders shall be distributed pro rata to the holders of
Common Stock (based on the number of shares of Common Stock then held by each
such holder).

          (c)  A liquidation, dissolution, or winding up within the meaning of
this Section 2 shall be deemed to be occasioned by, and to include, (i) any sale
of all or substantially all of the assets of the Corporation and (ii) any
consolidation, merger or other transaction or series of transactions pursuant to
which the holders of the outstanding voting securities of the Corporation
immediately prior to such consolidation, merger or other transaction or series
of transactions fail to hold equity securities representing a majority of the
voting power of the surviving entity immediately following such consolidation,
merger or other transaction or series of transactions.

          (d)  Any securities to be delivered to the holders of the Preferred
Stock or Common Stock pursuant to this Section 2 shall be valued as follows:

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

                      (1)  If traded on a national securities exchange or the
Nasdaq National Market (the "NMS"), the value shall be deemed to be the average
of the security's last reported sale prices on such exchange or the NMS over the
thirty (30) day period ending three (3) days prior to the closing;

                      (2)  If traded over-the-counter (but not on the NMS), the
value shall be deemed to be the average of the mean of the closing bid and ask
prices over the thirty (30) day period ending three (3) days prior to the
closing; or

                      (3)  If there is no active public market, the value shall
be the fair market value thereof, as mutually determined by the Corporation and
the holders of not less than fifty percent (50%) of the outstanding Preferred
Stock, voting together as a single class.

               (ii)   The method of valuation of securities subject to
investment letter or other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in Sections
2(d)(i)(1), (2) or (3) to reflect the approximate fair market value thereof, as
mutually determined by the Corporation and the holders of not less than fifty
percent (50%) of the outstanding Preferred Stock, voting together as a single
class.

                                      -3-
<PAGE>
 
          (e)  In the event the Corporation will not, at the closing of any
transaction identified in Sections 2(c)(i) or (ii) above, comply with the
requirements of this Section 2, the Corporation shall forthwith either:

               (i)    cause such closing to be postponed until such time as the
requirements of this Section 3 have been complied with, or

               (ii)   cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Preferred Stock shall revert to
and be the same as such rights, preferences and privileges existing immediately
prior to the date of the first notice referred to in Section 2(g) hereof.

          (f)  The Corporation shall give each holder of record of Preferred
Stock written notice of such impending transaction not later than twenty (20)
days prior to the shareholders' meeting called to approve a transaction
referenced in Sections 2(c)(i) and (ii), or twenty (20) days prior to the
closing of such transaction, whichever is earlier and shall also notify such
holders in writing of the final approval of such transaction. The first of such
notices shall describe the material terms and conditions of the impending
transaction and the provisions of this Section 2, and the Corporation shall
thereafter give such holders prompt notice of any material changes. The
transaction shall in no event take place sooner than twenty (20) days after the
Corporation has given the first notice provided for herein or sooner than ten
(10) days after the Corporation has given notice of any material changes
provided for herein. Notwithstanding the foregoing, the provisions of this
Section 2(f) may be waived, either prospectively or retrospectively, in whole or
in part, or any time period in this Section 2(f) may be shortened, in either
case, upon the written consent of the holders of the Preferred Stock which
represent at least a majority of the voting power of all then outstanding shares
of such Preferred Stock, voting together as a single class.

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

          (a)  Right to Convert.
               ---------------- 

               (i)    Each share of Preferred Stock shall be convertible into
shares of Common Stock, at the option of the holder thereof, at any time after
the date of issuance of such share, at the office of the Corporation or any
transfer agent for such stock. Each share of Preferred Stock shall be
convertible into the number of fully paid and nonassessable shares of Common
Stock which results from dividing the Conversion Price (as hereinafter defined)
per share in effect for each series of Preferred Stock at the time of conversion
into the per share Conversion Value (as hereinafter defined) of such series. As
of the date the Certificate of Incorporation is filed with the Delaware
Secretary of State, the Conversion Price per share of Series A Preferred Stock,
Series B Preferred Stock, Series C Preferred Stock and Series D Preferred Stock
shall be $1.00, $4.00, $5.35, and $8.00 respectively. The per share Conversion
Value shall be $1.00, $4.00, $5.35 and $8.00, respectively. The Conversion Price
of Series A Preferred Stock, Series B Preferred Stock, Series C 

                                      -4-
<PAGE>
 
Preferred Stock and Series D Preferred Stock shall be subject to adjustment from
time to time as provided below.

               (ii)   Each share of Preferred Stock shall automatically be
converted into shares of Common Stock at the then effective applicable
Conversion Price immediately upon the closing of the sale of the Corporation's
Common Stock in a firm commitment, underwritten public offering registered under
the Securities Act of 1933, as amended (other than a registration relating
solely to a transaction under Rule 145 under such Act (or any successor thereto)
or to an employee benefit plan of the Company), at a public offering price
(prior to underwriter commissions and expenses) equal to or exceeding seven
dollars and twenty-six cents ($7.26) per share of Common Stock (appropriately
adjusted for subdivisions and combinations of shares of Common Stock and
dividends on Common Stock payable in shares of Common Stock) and the aggregate
dollar amount of the offering (before deduction for underwriter commissions and
expenses relating to the issuance) of which exceeds seventeen million dollars
($17,000,000).

               (iii)  Each share of Preferred Stock shall automatically be
converted into shares of Common Stock at the then effective applicable
Conversion Price upon the vote or written consent of the holders of sixty-six
and two-thirds percent (66 2/3%) of the authorized shares of Preferred Stock
then outstanding, voting together as a single class.

          (b)  Mechanics of Conversion.  Before any holder of Preferred Stock
               -----------------------                                       
shall be entitled to convert the same into shares of Common Stock, he shall
surrender the certificate or certificates thereof, duly endorsed, at the office
of the Corporation or of any transfer agent for such stock, and shall give
written notice to the Corporation at such office that he elects to convert the
same and shall state therein the name or names in which he wishes the
certificate or certificates for shares of Common Stock to be issued. The
Corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Preferred Stock, a certificate or certificates for the
number of shares of Common Stock to which he shall be entitled as aforesaid.
Such conversion shall be deemed to have been made immediately prior to the close
of business on the date of surrender of the shares of Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock on such date. If the
conversion is in connection with an underwritten offer of securities registered
pursuant to the Securities Act of 1933, as amended, the conversion may, at the
option of any holder tendering Preferred Stock for conversion, be conditioned
upon the closing with the underwriter of the sale of securities pursuant to such
offering, in which event the person(s) entitled to receive the Common Stock
issuable upon such conversion of Preferred Stock shall not be deemed to have
converted such Preferred Stock until immediately prior to the closing of such
sale of securities.

          (c)  Adjustments to Conversion Price for Diluting Issues.
               --------------------------------------------------- 

               (i)    Special Definitions.  For purposes of this Section 3(c),

                           (E)  shares of Common Stock or other securities
issued or issuable to licensors of technology to the Corporation under any

               (ii)   No Adjustment of Conversion Price.  No adjustment to the
                      ---------------------------------                       
Conversion Price of any series of Preferred Stock shall be made in respect of
the issuance of Additional Shares of Common Stock unless the consideration per
share for any Additional Share of Common Stock issued or deemed to be issued by
the Corporation is less than the Conversion Price of such series of Preferred
Stock in effect on the date of, and immediately prior to, the issue of such

forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock

Securities and Options therefor, the conversion or exchange of such Convertible

Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

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

                      (3)  upon the expiration of any such Options or any rights
of conversion or exchange under such Convertible Securities which shall not have
been exercised, the Conversion Price computed upon the original issue thereof
(or upon the occurrence of a record date with respect thereto), and any
subsequent adjustments based thereon, shall, upon such expiration, be recomputed
as if:

                           (A)  in the case of Convertible Securities or Options
for Common Stock the only Additional Shares of Common Stock issued were the
shares of Common Stock, if any, actually issued upon the exercise of such
Options or conversion or exchange of such Convertible Securities and the
consideration received therefor was the consideration actually received by the
Corporation for the issue of all such Options, whether or not exercised, plus
the consideration actually received by the Corporation upon such exercise, or
for the issue of all such Convertible Securities which were actually converted
or exchanged, plus the additional consideration, if any, actually received by
the Corporation upon such conversion or exchange, and

                           (B)  in the case of Options for Convertible
Securities only the Convertible Securities, if any, actually issued upon the
exercise thereof were issued at the time of issue of such Options, and the
consideration received by the Corporation for the Additional Shares of common
Stock actually deemed to have been then issued was the consideration actually
received by the Corporation for the issue of all such Options, whether or not
exercised, plus the consideration 

                                      -7-
<PAGE>
 
actually received by the Corporation upon the issue of the Convertible
Securities with respect to which such Options were actually exercised;

                      (4)  no readjustment pursuant to clause (2) or (3) above
shall have the effect of increasing the Conversion Price for any series of
Preferred Stock to an amount which exceeds the lower of (i) such Conversion
Price on the original adjustment date, or (ii) such Conversion Price that would
have resulted from any issuance of Additional Shares of Common Stock between the
original adjustment date and such readjustment date; and

                      (5)  in the case of any Options which expire by their
terms not more than thirty (30) days after the date of issue thereof, no
adjustment of the Conversion Price shall be made until the expiration or
exercise of all such Options.

               (iv)   Adjustment of Conversion Price Upon Issuance of Additional
                      ----------------------------------------------------------
Shares of Common Stock.  If the Corporation shall issue Additional Shares of
- ----------------------                                                      
Common Stock (including Additional Shares of Common Stock deemed to be issued
pursuant to Section 3(c) (iii)) without consideration or for a consideration per
share less than the Conversion Price for any series of Preferred Stock in effect
on the date of and immediately prior to such issuance (excluding stock
dividends, distributions, subdivisions, split-ups, or combinations which are
covered by Sections 3(e) and 3(f)), then the Conversion Price for such series of
Preferred Stock shall be reduced, concurrently with such issuance, to a price
(calculated to the nearest tenth of a cent) equal to the quotient obtained by
dividing the total computed under clause (x) below by the total computed under
clause (y) below as follows:

               (x)    an amount equal to the sum of:

                      (1)  the total number of shares of Common Stock issuable
     upon conversion of all of the then outstanding shares of Preferred Stock
     (at the applicable Conver sion Prices for the Preferred Stock in effect
     immediately prior to such issuance) multiplied by the applicable Conversion
     Price for such series of Preferred Stock in effect immediately prior to
     such issuance, plus

                      (2)  the aggregate consideration, if any, received by the
     Corporation for such issuance;

               (y)    an amount equal to the sum of

                      (1)  the total number of shares of Common Stock issuable
     upon conversion of all of the then outstanding shares of Preferred Stock
     (at the applicable Conver sion Prices for the Preferred Stock in effect
     immediately prior to such issuance), plus

                      (2)  the Additional Shares of Common Stock issued in such
     issuance.

                                      -8-
<PAGE>
 
Notwithstanding the foregoing, the Conversion Price of a series of Preferred
Stock shall not be so reduced at such time if the amount of such reduction would
be an amount less than one-tenth of a cent ($0.001), but any such amount shall
be carried forward and reduction with respect thereto made at the time of and
together with any subsequent reduction which, together with such amount and any
other amount or amounts so carried forward, shall aggregate one-tenth of a cent
($0.001) or more.

               (v)    Determination of Consideration.  For purposes of this 
                      ------------------------------       
Section 3(c), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                      (1)  Cash and Property.  Such consideration shall:
                           -----------------                            

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

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

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

                      (2)  Options and Convertible Securities. The consideration
                           ----------------------------------      
per share received by the Corporation for Additional Shares of Common Stock
deemed to have been issued pursuant to Section 3(c)(iii), relating to Options
and Convertible Securities, shall be deter mined by dividing:

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

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

          d)   Adjustment to Conversion Price in the Event of a Forced or
               ----------------------------------------------------------
Automatic Conversion.  In the event of (i) a forced conversion of the Series C
- --------------------                                                          
Preferred Stock pursuant to Section 3(a)(iii) in connection with an initial
public offering at a price lower than $8.50 per share of Common Stock or (ii) an
automatic conversion of the Series C Preferred Stock pursuant to Section
3(a)(ii) at a price lower than $8.50 per share of Common Stock, then the
Conversion Price for the Series C Preferred Stock shall be reduced to $5.0156.
In the event of a forced conversion of the Series D Preferred Stock pursuant to
Section 3(a)(iii) in connection with an initial public offering at a price lower
than $8.00 per share of Common Stock or (ii) an automatic conversion of the
Series D Preferred Stock pursuant to Section 3(a)(ii) at a price lower than
$8.00 per share of Common Stock, then the Conversion Price for the Series D
Preferred stock shall be reduced to the amount of such initial public offering
price. The above numbers are subject to adjustment for subdivisions and
combinations of shares of Common Stock and dividends on Common Stock payable in
shares of Common Stock.

          e)   Adjustments to Conversion Price for Other Events.  The Conversion
               ------------------------------------------------                 
Price shall be subject to adjustment from time to time as follows:

               (vi)   If the number of shares of Common Stock outstanding is
increased by a stock dividend or distribution payable in shares of Common Stock
or by a subdivision or split-up of shares of Common Stock, then, as of the
record date fixed for the determination of holders of Common Stock entitled to
receive such stock dividend, distribution, subdivision or split-up (or the date
of such dividend, distribution, split-up or subdivision if no record date is
fixed), the Conversion Price of each series of Preferred Stock shall be
appropriately decreased so that the number of shares of Common Stock issuable on
conversion of each share of Preferred Stock shall be increased in proportion to
such increase of outstanding shares of Common Stock.

               (vii)  If the number of shares of Common Stock outstanding is
decreased by a combination of the outstanding shares of Common Stock, then,
following the record date of such combination, the Conversion Price of each
series of Preferred Stock shall be appropriately increased so that the number of
shares of Common Stock issuable on conversion of each share of Preferred Stock
shall be decreased in proportion to such decrease in outstanding shares of
Common Stock.

          (f)  Other Distributions. In the event the Corporation shall declare a
               -------------------      
distribution payable in securities of other persons, evidence of indebtedness
issued by the Corporation or other persons, or assets, options or rights not
referred to in Section 3(c) hereof, then, in each such case, provision shall be
made so that the holders of the Preferred Stock shall be entitled to receive,
upon the conversion thereof, the consideration per share which they would have
received had their Preferred Stock been converted into Common Stock on the date
of such event.

          (g)  No Impairment.  The Corporation will not, through any
               -------------                                        
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities, avoid or seek to avoid the observance or performance of any
of the terms to be observed or performed hereunder by the Corporation, but will
at all times in good faith assist in the carrying out of all the provisions of

                                      -10-
<PAGE>
 
this Section 3 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Preferred Stock against impairment.

          (h)  Certificates as to Adjustments.  Upon the occurrence of each
               ------------------------------                              
adjustment or readjustment of the Conversion Price of any series of Preferred
Stock pursuant to this Section 3, the Corporation at its expense shall promptly
compute such adjustment or readjustment in accordance with the terms hereof and
furnish to each holder of Preferred Stock the Conversion Price of which has been
adjusted a certificate signed by the chief executive officer or the chief
financial officer of the Company setting forth such adjustment or readjustment
and showing in detail the facts upon which such adjustment or readjustment is
based.  The Corporation shall, upon the written request at any time of any
holder of Preferred Stock, furnish or cause to be furnished to such holder a
like certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price at the time in effect, and (iii) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of the Preferred Stock.

          (i)  Notices of Record Date.  In the event of any taking by the
               ----------------------                                    
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any security or
right convertible into or entitling the holder thereof to receive Common Stock
or other securities of the Company, or any right to subscribe for, purchase or
otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, the Corporation shall mail to each
holder of Preferred Stock at least twenty (20) days prior to the date specified
therein, a notice specifying the date on which any such record is to be taken
for the purpose of such dividend, distribution, security or right, and the
amount and character of such dividend, distribution, security or right.

          (j)  Issue Taxes.  The Corporation shall pay any and all issue and
               -----------                                                  
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of shares of Preferred Stock pursuant hereto;
provided, however, that the Corporation shall not be obligated to pay any
transfer taxes resulting from any transfer requested by any holder in connection
with any such conversion.

          (k)  Reservation of Stock Issuable Upon Conversion.  The Corporation
               ---------------------------------------------                  
shall at all times reserve and keep available out of its authorized but unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Preferred Stock; and if at any time the number of
authorized but unissued shares of Common Stock shall not be sufficient to effect
the conversion of all then outstanding shares of the Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose,
including, without limitation, engaging in best efforts to obtain the requisite
shareholder approval of any necessary amendment to this Certificate.

          (l)  Fractional Shares.  No fractional share shall be issued upon the
               -----------------                                               
conversion of any share or shares of Preferred Stock. All shares of Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
Preferred Stock by a holder thereof shall be aggregated for purposes of
determining whether the conversion would result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of a fraction of a share of Common Stock, the Corporation
shall, in lieu of issuing any fractional share, pay the holder otherwise
entitled to such fraction a sum in cash equal to the fair market value of such
fraction on the date of conversion (as determined in good faith by the Board of
Directors of the Corporation).

          (m)  Notices.  Any notice required by the provisions of this Section 3
               -------                                                          
to be given to the holders of shares of Preferred Stock shall be deemed given if
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at his address appearing on the books of the Corporation.

          (n)  Adjustments.  In case of any reorganization or any
               -----------                                       
reclassification of the capital stock of the Corporation, any consolidation or
merger of the Corporation with or into another corporation or corporations, or
the conveyance of all or substantially all of the assets of the Corporation to
another corporation (other than a subdivision, combination or merger or sale of
assets transaction provided for elsewhere in Section 2 or in this Section 3),
each share of Preferred Stock shall thereafter be convertible into the number of
shares of stock or other securities or property (including cash) to which a
holder of the number of shares of Common Stock deliverable upon conversion of
such share of Preferred Stock would have been entitled upon the record date of
(or date of, if no record date is fixed) such reorganization, reclassification,
consolidation, merger or conveyance; and, in any case, appropriate adjustment
(as determined by the Board of Directors) shall be made in the application of
the provisions herein set forth with respect to the rights and interests
thereafter of the holders of such Preferred Stock, to the end that the
provisions set forth herein shall thereafter be applicable, as nearly as
equivalent as is practicable, in relation to any shares of stock or the
securities or property (including cash) thereafter deliverable upon the
conversion of the shares of Preferred Stock.

     4.   Voting Rights.  Except as otherwise expressly provided herein or as
          -------------                                                      
required by law, the holder of each share of the Preferred Stock shall be
entitled to the number of votes equal to the number of shares of Common Stock
into which such share of Preferred Stock could be converted and shall have
voting rights and powers equal to the voting rights and powers of the Common
Stock (except as otherwise expressly provided herein or as required by law,
voting together with the Common Stock as a single class) and shall be entitled
to notice of any shareholders' meeting in accordance with the Bylaws of the
Corporation. Fractional votes shall not, however, be permitted and any
fractional voting rights resulting from the above formula (after aggregating all
shares into which shares of Preferred Stock held by each holder could be
converted) shall be rounded to the nearest whole number (with one-half being
rounded upward).

     5.   Covenants.  So long as at least five hundred thousand (500,000) shares
          ---------                                                             
of the Preferred Stock shall be outstanding, the Corporation shall not, without
first obtaining the approval (by vote or written consent, as provided by law) of
the holders of at least a majority in interest of the then outstanding shares of
Preferred Stock, voting together as a single class and on an as if converted
basis:

          (a)  effect any sale of all or substantially all of the assets of the
Corporation or any merger or consolidation of the Corporation with another
corporation;

          (b)  take any action (other than of a ministerial nature, including
the registration of a transfer on the books and records of the Corporation) to
initiate a transfer of 50% or more in interest (determined on an as converted
basis) of the capital stock of the Corporation in a single transaction or a
series of related transactions;

          (c)  amend or repeal any provision of, or add any provision to, the
Corporation's Certificate of Incorporation if such action would increase the
authorized number of shares of Preferred Stock, or alter or change the rights,
preferences, privileges or limitations provided for the benefit of the Preferred
Stock;

          (d)  create any series or class of stock having any preference or
priority as to dividends, redemption, voting, liquidation, conversion or assets
superior to or on a parity with any such preference or priority of the Series A
Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock and
Series D Preferred Stock; or

          (e)  amend or repeal any provision of, or add any provision to, the
Corporation's Bylaws if such action would increase the authorized number of
directors of the Company to more than seven (7) directors.

                                  ARTICLE VI.

     The following is applicable to the Common Stock:

                                 ARTICLE VII.

     The liability of the directors of the Corporation for monetary damages
shall be eliminated to the fullest extent permissible under the General
Corporation Law of Delaware.  Any repeal or modification of this Article shall

     Holders of stock of any class or series of this corporation shall not be
entitled to cumulate their votes for the election of directors or any other
matter submitted to a vote of the stockholders, unless such cumulative voting is
required pursuant to the General Corporation Law of Delaware, in which event
each such holder shall be entitled to as many votes as shall equal the number of
votes which (except for this provision as to cumulative voting) such holder
would be entitled to cast for the election of directors with respect to his
shares of stock multiplied by the number of directors to be elected by him, and
the holder may cast all of such votes for a single director or may distribute
them among the number of directors to be voted for, or for any two or more of
them as such holder may see fit, so long as the name of the candidate for
director shall have been placed in nomination prior to the voting and the
stockholder, or any other holder of the same class or series of stock, has given
notice at the meeting prior to the voting of the intention to cumulate votes.

                                  ARTICLE X.

     1.   Number of Directors.  The board of directors shall consist of not less

     2.   Election of Directors.  Elections of directors need not be by written

determine or alter the rights, preferences, privileges and restrictions granted
to or imposed upon any wholly unissued series of Preferred Stock and to fix the
number of shares of any series of Preferred Stock and the designation of any
such series of Preferred Stock. The Board of Directors, within the limits and
restrictions stated in any resolution or resolutions of the Board of Directors
originally fixing the number of shares constituting any series, may increase or
decrease (but not below the number of shares in any such series then
outstanding) the number of shares of any series subsequent to the issue of
shares of that series.

     The authority of the Board of Directors with respect to each such class or
series shall include, without limitation of the foregoing, the right to
determine and fix:

          (a) the distinctive designation of such class or series and the number
of shares to constitute such class or series;

          (b) the rate at which dividends on the shares of such class or series
shall be declared and paid, or set aside for payment, whether dividends at the
rate so determined shall be cumulative or accruing, and whether the shares of
such class or series shall be entitled to any participating or other dividends
in addition to dividends at the rate so determined, and if so, on what terms;

          (c) the right or obligation, if any, of the corporation to redeem
shares of the particular class or series of Preferred Stock and, if redeemable,
the price, terms and manner of such redemption;

          (d) the special and relative rights and preferences, if any, and the
amount or amounts per share, which the shares of such class or series of
Preferred Stock shall be entitled to receive upon any voluntary or involuntary
liquidation, dissolution or winding up of the Corporation;

          (e) the terms and conditions, if any, upon which shares of such class
or series shall be convertible into, or exchangeable for, shares of capital
stock of any other class or series, including the price or prices or the rate or
rates of conversion or exchange and the terms of adjustment, if any;

          (f) the obligation, if any, of the corporation to retire, redeem or
purchase shares of such class or series pursuant to a sinking fund or fund of a
similar nature or otherwise, and the terms and conditions of such obligation;

          (g) voting rights, if any, on the issuance of additional shares of
such class or series or any shares of any other class or series of Preferred
Stock;

          (h) limitations, if any, on the issuance of additional shares of such
class or series or any shares of any other class or series of Preferred Stock;
and

          (i) such other preferences, powers, qualifications, special or
relative rights and privileges thereof as the Board of Directors of the
corporation, acting in accordance with this Restated

the adoption of any provision of the Corporation's Certificate of Incorporation
inconsistent with this Article VII, shall eliminate or reduce the effect of this
Article VII, in respect of any matter occurring, or any action or proceeding
accruing or arising or that, but for this Article VII, would accrue or arise,
prior to such amendment, repeal, or adoption of an inconsistent provision.


                                  ARTICLE VII

     In the event any shares of Preferred Stock shall be redeemed or converted
pursuant to the terms hereof, the shares so converted or redeemed shall not

     Holders of stock of any class or series of this corporation shall not be
entitled to cumulate their votes for the election of directors or any other
matter submitted to a vote of the stockholders, unless such cumulative voting is
required pursuant to Sections 2115 and/or 301.5 of the California Corporations
Code, in which event each such holder shall be entitled to as many votes as
shall equal the number of votes which (except for this provision as to

directors with respect to his shares of stock multiplied by the number of
directors to be elected by him, and the holder may cast all of such votes for a
single director or may distribute them among the number of directors to be voted

the voting and the stockholder, or any other holder of the same class or series
of stock, has given notice at the meeting prior to the voting of the intention

to cast not less than ten percent (10%) of the votes at that meeting.  No other
person or persons are permitted to call a special meeting.

     If a special meeting is called by any person or persons other than the

such meeting and the general nature of the business proposed to be transacted,
and shall be delivered personally or sent by registered mail or by telegraphic

notice to be promptly given to the stockholders entitled to vote, in accordance
with the provisions of Sections 2.4 and 2.6 of these bylaws, that a meeting will
be held at the time requested by the person or persons calling the meeting, so
long as that time is not less than thirty-five (35) nor more than sixty (60)
days after the receipt of the request.  If the notice is not given within twenty
(20) days after receipt of the request, then the person or persons requesting
the meeting may give the notice.  Nothing contained in this paragraph of this

     2.4  NOTICE OF STOCKHOLDERS' MEETINGS
          --------------------------------

     All notices of meetings of stockholders shall be sent or otherwise given in

giving the notice, intends to present for action by the stockholders (but any
proper matter may be presented at the meeting for such action).  The notice of

nominee or nominees who, at the time of the notice, the board intends to present
for election.

     2.5 ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS
         ---------------------------------------------------------------

     Subject to the rights of holders of any class or series of stock having a
preference over the Common Stock as to dividends or upon liquidation,

     (a) nominations for the election of directors, and

     (b) business proposed to be brought before any stockholder meeting
<PAGE>
 
may be made by the board of directors or proxy committee appointed by the board
of directors or by any stockholder entitled to vote in the election of directors
generally if such nomination or business proposed is otherwise proper business
before such meeting.  However, any such stockholder may nominate one or more
persons for election as directors at a meeting or propose business to be brought
before a meeting, or both, only if such stockholder has given timely notice in
proper written form of their intent to make such nomination or nominations or to
propose such business.  To be timely, such stockholder's notice must be
delivered to or mailed and received at the principal executive offices of the
corporation not less than one hundred twenty (120) calendar days in advance of
the date specified in the corporation's proxy statement released to stockholders
in connection with the previous year's annual meeting of stockholders; provided,
however, that in the event that no annual meeting was held in the previous year
or the date of the annual meeting has been changed by more than thirty (30) days
from the date contemplated at the time of the previous year's proxy statement,
notice by the stockholder to be timely must be so received a reasonable time
before the solicitation is made.  To be in proper form, a stockholder's notice
to the secretary shall set forth:

     (i) the name and address of the stockholder who intends to make the
     nominations or propose the business and, as the case may be, of the person
     or persons to be nominated or of the business to be proposed;

     (ii) a representation that the stockholder is a holder of record of stock
     of the corporation entitled to vote at such meeting and, if applicable,
     intends to appear in person or by proxy at the meeting to nominate the
     person or persons specified in the notice;

     (iii)  if applicable, a description of all arrangements or understandings
     between the stockholder and each nominee and any other person or persons
     (naming such person or persons) pursuant to which the nomination or
     nominations are to be made by the stockholder;

     (iv) such other information regarding each nominee or each matter of
     business to be proposed by such stockholder as would be required to be
     included in a proxy statement filed pursuant to the proxy rules of the
     Securities and Exchange Commission had the nominee been nominated, or
     intended to be nominated, or the matter been proposed, or intended to be
     proposed by the board of directors; and

     (v) if applicable, the consent of each nominee to serve as director of the
     corporation if so elected.

     The chairman of the meeting shall refuse to acknowledge the nomination of
any person or the proposal of any business not made in compliance with the
foregoing procedure.

     2.6  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
          --------------------------------------------

     Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication.  Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice. Notice shall be deemed to have been given
at the time when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.

     An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

     2.7  QUORUM
          ------

     The holders of a majority in voting power of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation.  If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting in accordance
with Section 2.8 of these bylaws.

     When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one upon which, by express provision of the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

     If a quorum be initially present, the stockholders may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

     2.8  ADJOURNED MEETING; NOTICE
          -------------------------

     When a meeting is adjourned to another time and place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting. If the adjournment is for
more than thirty (30) days, or if after the adjournment a new record date is
fixed for the adjourned meeting, a notice of the adjourned meeting shall be
given to each stockholder of record entitled to vote at the meeting.

     2.9  VOTING
          ------

                                      -4-
<PAGE>
 
     The stockholders entitled to vote at any meeting of stockholders shall be
determined in accordance with the provisions of Section 2.13 of these bylaws,
subject to the provisions of Sections 217 and 218 of the General Corporation Law
of Delaware (relating to voting rights of fiduciaries, pledgors and joint
owners, and to voting trusts and other voting agreements).

     Except as may be otherwise provided in the certificate of incorporation or
these bylaws, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder and stockholders shall not be entitled to
cumulate their votes in the election of directors or with respect to any matter
submitted to a vote of the stockholders.

     Notwithstanding the foregoing, if the stockholders of the corporation are
entitled, pursuant to Sections 2115 and 301.5 of the California Corporations
Code, to cumulate their votes in the election of directors, each such
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes that such stockholder normally
is entitled to cast) only if the candidates' names have been properly placed in
nomination (in accordance with these bylaws) prior to commencement of the
voting, and the stockholder requesting cumulative voting has given notice prior
to commencement of the voting of the stockholder's intention to cumulate votes.
If cumulative voting is properly requested, each holder of stock, or of any
class or classes or of a series or series thereof, who elects to cumulate votes
shall be entitled to as many votes as equals the number of votes that (absent
this provision as to cumulative voting) he or she would be entitled to cast for
the election of directors with respect to his or her shares of stock multiplied
by the number of directors to be elected by him, and he or she may cast all of
such votes for a single director or may distribute them among the number to be
voted for, or for any two or more of them, as he or she may see fit.

     2.10 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING
          ------------------------------------------

     For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the board of directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the board of directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

     If the board of directors does not so fix a record date, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the business day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

     A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting
unless the board of directors fixes a new record date for the adjourned meeting,
but the board of directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

                                      -5-
<PAGE>
 
     The record date for any other purpose shall be as provided in Section 8.1
of these bylaws.

     2.11 PROXIES
          -------

     Every person entitled to vote for directors, or on any other matter, shall
have the right to do so either in person or by one or more agents authorized by
a written proxy signed by the person and filed with the secretary of the
corporation, but no such proxy shall be voted or acted upon after three (3)
years from its date, unless the proxy provides for a longer period.  A proxy
shall be deemed signed if the stockholder's name is placed on the proxy (whether
by manual signature, typewriting, telegraphic transmission, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact.  The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
Delaware.

     2.12 ORGANIZATION
          ------------

     The president, or in the absence of the president, the chairman of the
board, or, in the absence of the president and the chairman of the board, one of
the corporation's vice presidents, shall call the meeting of the stockholders to
order, and shall act as chairman of the meeting.  In the absence of the
president, the chairman of the board, and all of the vice presidents, the
stockholders shall appoint a chairman for such meeting.  The chairman of any
meeting of stockholders shall determine the order of business and the procedures
at the meeting, including such matters as the regulation of the manner of voting
and the conduct of business.  The secretary of the corporation shall act as
secretary of all meetings of the stockholders, but in the absence of the
secretary at any meeting of the stockholders, the chairman of the meeting may
appoint any person to act as secretary of the meeting.

     2.13 LIST OF STOCKHOLDERS ENTITLED TO VOTE
          -------------------------------------

     The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  Such list shall be open
to the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held.  The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

     2.14 WAIVER OF NOTICE
          ----------------

     Whenever notice is required to be given under any provision of the General
Corporation Law of Delaware or of the certificate of incorporation or these
bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except 

                                      -6-
<PAGE>
 
when the person attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened. Neither the business to be transacted at,
nor the purpose of, any regular or special meeting of the stockholders need be
specified in any written waiver of notice unless so required by the certificate
of incorporation or these bylaws.


                                  ARTICLE III

                                   DIRECTORS
                                   ---------

     3.1 POWERS
         ------

     Subject to the provisions of the General Corporation Law of Delaware and to
any limitations in the certificate of incorporation or these bylaws relating to
action required to be approved by the stockholders or by the outstanding shares,
the business and affairs of the corporation shall be managed and all corporate
powers shall be exercised by or under the direction of the board of directors.


     3.2 NUMBER OF DIRECTORS
         -------------------

     The board of directors shall not be less than five (5) nor more than seven
(7) members.  The exact number of directors shall be six (6) until changed,
within the limits specified above by a bylaw amending this Section 3.2 duly
adopted by the board of directors or the stockholders.  The indefinite number of
directors may be changed, or a definite number may be fixed without provision
for an indefinite number, by an amendment to this bylaw, duly adopted by the
board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation.  No reduction of the authorized number of
directors shall have the effect of removing any director before that director's
term of office expires.

     Upon the IPO (as defined in Section 2.3), the directors shall be divided
into three classes, with the term of office of the first class, which class
shall initially consist of two directors, to expire at the first annual meeting
of stockholders held after the IPO; the term of office of the second class,
which class shall initially consist of two directors, to expire at the second
annual meeting of stockholders held after the IPO; the  term of office of the
third class, which class shall initially consist of two directors, to expire at
the third annual meeting of stockholders held after the IPO; and thereafter for
each such term to expire at each third succeeding annual meeting of stockholders
held after such election.

     3.3 ELECTION AND TERM OF OFFICE OF DIRECTORS
         ----------------------------------------

     Except as provided in Section 3.4 of these bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting. Each director, including a director elected or appointed to fill
a vacancy, shall hold office until the expiration of the term for which elected
and until a successor has been elected and qualified.

                                      -7-
<PAGE>
 
     3.4 RESIGNATION AND VACANCIES
         -------------------------

     Any director may resign effective on giving written notice to the chairman
of the board, the president, the secretary or the board of directors, unless the
notice specifies a later time for that resignation to become effective.  If the
resignation of a director is effective at a future time, the board of directors
may elect a successor to take office when the resignation becomes effective.

     Vacancies in the board of directors may be filled by a majority of the
remaining directors, even if less than a quorum, or by a sole remaining
director; however, a vacancy created by the removal of a director by the vote of
the stockholders or by court order may be filled only by the affirmative vote of
a majority of the shares represented and voting at a duly held meeting at which
a quorum is present (which shares voting affirmatively also constitute a
majority of the required quorum).  Each director so elected shall hold office
until the next annual meeting of the stockholders and until a successor has been
elected and qualified.

     Unless otherwise provided in the certificate of incorporation or these
bylaws:

          (i)  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (ii) Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
certificate of incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

     If at any time, by reason of death or resignation or other cause, the
corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

     If, at the time of filling any vacancy or any newly created directorship,
the directors then in office constitute less than a majority of the whole board
(as constituted immediately prior to any such increase), then the Court of
Chancery may, upon application of any stockholder or stockholders holding at
least ten (10) percent of the total number of the shares at the time outstanding
having the right to vote for such directors, summarily order an election to be
held to fill any such vacancies or newly created directorships, or to replace
the directors chosen by the directors then in office as aforesaid, which
election shall be governed by the provisions of Section 211 of the General
Corporation Law of Delaware as far as applicable.

     3.5 REMOVAL OF DIRECTORS
         --------------------

     Unless otherwise restricted by statute, by the certificate of incorporation
or by these bylaws, any director or the entire board of directors may be
removed, with or without cause, by the holders of a majority of the shares then
entitled to vote at an election of directors; provided, however, that, if and so
long as stockholders of the corporation are entitled to cumulative voting, if
less than the entire board is to be removed, no director may be removed without
cause if the votes cast against his removal would be sufficient to elect him if
then cumulatively voted at an election of the entire board of directors.

     3.6 PLACE OF MEETINGS; MEETINGS BY TELEPHONE
         ----------------------------------------

     Regular meetings of the board of directors may be held at any place within

certificate of incorporation and applicable law.

     A meeting at which a quorum is initially present may continue to transact
business notwithstanding the withdrawal of directors, if any action taken is
approved by at least a majority of the quorum for that meeting.


     3.10  WAIVER OF NOTICE
           ----------------

     Notice of a meeting need not be given to any director (i) who signs a
waiver of notice, whether before or after the meeting, or (ii) who attends the
meeting other than for the express purposed of objecting at the beginning of the
meeting to the transaction of any business because the meeting is not lawfully
called or convened. All such waivers shall be filed with the corporate records
or made part of the minutes of the meeting. A waiver of notice need not specify
the purpose of any regular or special meeting of the board of directors.

bylaws, to the directors who were not present at the time of the adjournment.

     3.13  BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

     Any action required or permitted to be taken by the board of directors may
be taken without a meeting, provided that all members of the board individually

directors shall approve, including, without limitation, a pledge of shares of
stock of the corporation.  Nothing contained in this section shall be deemed to

may exercise all the powers and authority of the board, but no such committee
shall have the power or authority to (i) amend the certificate of incorporation
(except that a committee may, to the extent authorized in the resolution or
resolutions providing for the issuance of shares of stock adopted by the board
of directors as provided in Section 151(a) of the General Corporation Law of
Delaware, fix the designations and any of the preferences or rights of such
shares relating to dividends, redemption, dissolution, any distribution of
assets of the corporation or the conversion into, or the exchange of such shares
for, shares of any other class or classes or any other series of the same or any
other class or classes of stock of the corporation), (ii) adopt an agreement of
merger or consolidation under Sections 251 or

stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, (iv) recommend to the stockholders a
dissolution of the corporation or a revocation of a dissolution or (v) amend the
bylaws of the corporation; and, unless the board resolution establishing the
committee, the bylaws or the certificate of incorporation expressly so provide,

the committee, that special meetings of committees may also be called by
resolution of the board of directors, and that notice of special meetings of

     The corporation shall pay the expenses (including attorney's fees) incurred
by a director or officer of the corporation entitled to indemnification

Section 6.1 in advance of its final disposition; provided, however, that payment
of expenses incurred by a director or officer of the corporation in advance of
the final disposition of such action, suit or proceeding shall be made only upon
receipt of an undertaking by the director or officer

                                     -16-

of any other rights which such person may have or hereafter acquire under any
statute, provision of the corporation's Certificate of Incorporation, these
bylaws, agreement, vote of the stockholders or disinterested directors or
otherwise.

     Any repeal or modification of the foregoing provisions of this Article

modification.

the corporation (other than a director or officer) shall mean any person (i) who
is or was an employee or agent of the corporation, (ii) who is or was serving at
the request of the corporation as an employee or agent of another corporation,

employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred

                                GENERAL MATTERS
                                ---------------

     8.1   RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
           -----------------------------------------------------

     For purposes of determining the stockholders entitled to receive payment of
any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the board of directors may fix, in advance, a record date, which shall not
precede the date upon which the resolution fixing the record date is adopted and
which shall not be more than sixty (60) days before any such action.  In that
case, only stockholders of record at the close of business on the date so fixed
are entitled to receive the dividend, distribution or allotment of rights, or to
exercise such rights, as the case may be, notwithstanding any transfer of any
shares on the books of the corporation after the record date so fixed, except as
otherwise provided by law.

     If the board of directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the board of directors adopts the applicable
resolution.

     8.2   CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS
           -----------------------------------------

     From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for

shall sign or endorse those instruments.

     The board of directors, except as otherwise provided in these bylaws, may
authorize and empower any officer or officers, or agent or agents, to enter into
any contract or execute any instrument in the name of and on behalf of the
corporation; such power and authority may be general or confined to specific
instances.  Unless so authorized or ratified by the board of directors or within
the agency power of an officer, no officer, agent or employee shall have any
power or authority to bind the corporation by any contract or engagement or to
pledge its credit or to render it liable for any purpose or for any amount.

     8.4   STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES
           ------------------------------------------------

     The shares of the corporation shall be represented by certificates,
provided that the board of directors of the corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares. Any such resolution shall not apply to
shares represented by a certificate until such certificate is surrendered to the
corporation. Notwithstanding the adoption of such a resolution by the board of
directors, every holder of stock represented by certificates and, upon request,
every holder of uncertificated shares, shall be entitled to have a certificate
signed by, or in the name of the corporation by, the chairman or vice-chairman
of the board of directors, or the president or vice-president, and by the
treasurer or an assistant treasurer, or the secretary or an assistant secretary
of such corporation representing the number of shares registered in certificate
form. Any or all of the signatures on the certificate may be a facsimile. In
case any officer, transfer agent or registrar who has signed or whose facsimile
signature has been placed upon a certificate has ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he or she were such officer,
transfer agent or registrar at the date of issue.

     Certificates for shares shall be of such form and device as the board of
directors may designate and shall state the name of the record holder of the
shares represented thereby; its number; date of issuance; the number of shares
for which it is issued; a summary statement or reference to the powers,
designations, preferences or other special rights of such stock and the
qualifications, limitations or restrictions of such preferences and/or rights,
if any; a statement or summary of liens, if any; a conspicuous notice of
restrictions upon transfer or registration of transfer, if any; a statement as
to any applicable voting trust agreement; if the shares be assessable, or, if
assessments are collectible by personal action, a plain statement of such facts.

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

     The corporation may issue the whole or any part of its shares as partly
paid and subject to call for the remainder of the consideration to be paid
therefor. Upon the face or back of each stock certificate issued to represent
any such partly paid shares, or upon the books and records of the corporation in
the case of uncertificated partly paid shares, the total amount of the
consideration to be paid therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class, but only upon the
basis of the percentage of the consideration actually paid thereon.

     8.5   SPECIAL DESIGNATION ON CERTIFICATES
           -----------------------------------

     If the corporation is authorized to issue more than one class of stock or
more than one series of any class, then the powers, the designations, the
preferences and the relative, participating, optional or other special rights of
each class of stock or series thereof and the qualifications, limitations or

                                     -20-
<PAGE>
 
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the corporation shall issue to represent
such class or series of stock a statement that the corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

     Except as provided in this Section 8.6, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation and cancelled at the same time. The board of
directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates on such terms and conditions as the board may require; the board
may require indemnification of the corporation secured by a bond or other
adequate security sufficient to protect the corporation against any claim that
may be made against it, including any expense or liability, on account of the
alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

     8.7   TRANSFER AGENTS AND REGISTRARS
           ------------------------------

     The board of directors may appoint one or more transfer agents or transfer
clerks, and one or more registrars, each of which shall be an incorporated bank
or trust company -- either domestic or foreign, who shall be appointed at such
times and places as the requirements of the corporation may necessitate and the
board of directors may designate.

     8.8   CONSTRUCTION; DEFINITIONS
           -------------------------

     Unless the context requires otherwise, the general provisions, rules of
construction and definitions in the General Corporation Law of Delaware shall
govern the construction of these bylaws. Without limiting the generality of this
provision, as used in these bylaws, the singular number includes the plural, the
plural number includes the singular, and the term "person" includes both an
entity and a natural person.


                                  ARTICLE IX

                                  AMENDMENTS
                                  ----------

     The original or other bylaws of the corporation may be adopted, amended or
repealed by the stockholders entitled to vote or by the board of directors of
the corporation.  The fact that such power has been so conferred upon the
directors shall not divest the stockholders of the power, nor limit their

                                     -21-
<PAGE>
 
power to adopt, amend or repeal bylaws.

     Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place. If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

Re: Registration Statement on Form S-1

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1 (File No. 333-
40339) filed with the Securities and Exchange Commission on November 17, 1997
(as amended by Amendment No. 1 thereto filed on January 12, 1998, as such may be
amended or supplemented, the "Registration Statement"), in connection with the
registration under the Securities Act of 1933, as amended, of 2,300,000 shares
of Common Stock of Symphonix Devices, Inc. (the "Shares"). The Shares, which
include up to 345,000 shares of Common Stock issuable pursuant to an over-
allotment option granted to the underwriters, are to be sold to the underwriters
as described in such Registration Statement for the sale to the public or issued
to the Representatives of the underwriters. As your counsel in connection with
this transaction, we have examined the proceedings proposed to be taken in
connection with said sale and issuance of the Shares.

     It is our opinion that, upon approval by the pricing committee duly
authorized by the Company's Board of Directors, the Shares when issued and
sold in the manner referred to in the Registration Statement will be legally
and validly issued, fully paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration 
Statement, and further consent to the use of our name wherever appearing in the 
Registration Statement, including the prospectus constituting a part hereof, and
any amendment thereto.

                                        Very truly yours,

                                        /s/ Wilson Sonsini Goodrich & Rosati

       THIS LOAN AND SECURITY AGREEMENT is dated December 30, 1997, between
SILICON VALLEY BANK ("Bank"), whose address is 3003 Tasman Drive, Santa Clara,
CA  95054 with a loan production office located at 1731 Embarcadero, Ste. 220,
Palo Alto, California  94303 and SYMPHONIX DEVICES, INC. ("Borrower"), whose
address is 3047 Orchard Parkway, San Jose, California  95134 provides the terms
on which Bank will lend to Borrower and Borrower will repay Bank. The parties
agree as follows:

1      ACCOUNTING AND OTHER TERMS
       --------------------------

       Accounting terms not defined in this Agreement will be construed
following GAAP Calculations and determinations must be made following GAAP. The
term "financial statements" includes the notes and schedules. The terms
"including" and "includes" always mean "including (or includes) without
limitation," in this or any Loan Document. This Agreement shall be construed to
impart upon Bank a duty to act reasonably at all times.

2      LOAN AND TERMS OF PAYMENT
       -------------------------
2.1    CREDIT EXTENSIONS.

       Borrower will pay Bank the unpaid principal amount of all Credit
Extensions and interest on the unpaid principal amount of the Credit Extensions
as set forth in this Agreement.

2.1.1  Letter of Credit Facility.

       Bank will issue or have issued Letters of Credit for Borrower's account
on or before the Availability End Date. The face amount of outstanding Letters
of Credit (including drawn but unreimbursed Letters of Credit and any Letter of
Credit Reserve) may not exceed $250,000. Each Letter of Credit will have an
expiry date of no later than 180 days after the Letter of Credit Maturity Date,
but Borrower's reimbursement obligation will be secured by cash or cash
equivalents on terms reasonably acceptable to Bank at any time after the Letter
of Credit Maturity Date if the term of this Agreement is not extended by Bank.

2.1.2  Advances.

       (a)  Through December 31, 1998 (the "Availability End Date"), Bank agrees
to make advances ("Advance" and, collectively, " Advances") not exceeding the
Committed Line at any one time outstanding.

       (b)  Interest accrues from the date of each Advance at the rate in
Section 2.2((a)) and is payable monthly until the Availability End Date occurs.
The principal amount of Advances outstanding at the close of business on the
Availability End Date are payable in 48 equal monthly installments of principal
beginning on the last day of each month following the Availability End Date and
ending on the December 31, 2002 (the "Loan Maturity Date"). Amounts borrowed
pursuant to this Section 2.1.2 may be repaid and reborrowed at any time prior to
the Availability End Date provided that the aggregate principal amount of all
advances outstanding at any one time shall not exceed the Committed Line
Borrower may prepay the Advances in whole or in part at any time after the
Availability End Date together with any Prepayment Fee (with respect to any
principal amounts accruing interest at a fixed rate). Prepayment of principal
made after the Availability End Date shall be applied against installments in
the order of maturity.

       (c)  To obtain an Advance, Borrower must notify Bank (the notice is
irrevocable) by facsimile no later than 3:00 p.m. Pacific time 1 Business Day
before the day on which the Advance is to be made. The notice in the form of
Exhibit B (Payment/Advance Form) must be signed by a Responsible Officer or
designee.

2.2    INTEREST RATE, PAYMENTS.

       (a)  Interest Rate.  Prior to the Availability End Date, Advances accrue
interest on the outstanding principal balance at a per annum rate of 0.75
percentage points above the Prime Rate. Advances outstanding as of the
Availability End Date accrue interest at Borrower's option of either (i) a fixed
rate equal to 350 basis points above the Treasury Note Rate or (ii) a variable
per annum rate of 0.75 percentage points above the Prime Rate. After an Event of
Default, Obligations accrue interest at 5 percent above the rate effective
immediately before the Event of Default. The interest rate increases or
decreases when the Prime Rate changes. In the event Borrower elects the fixed
rate option, the Prepayment fee will apply. Interest is computed on a 360 day
year for the actual number of days elapsed.

       (b)  Payments.  Interest due on the Advances is payable on the last day
of each month. Bank may debit any of Borrower's deposit accounts including
Account Number __________________________ for principal and interest payments or
any amounts Borrower owes Bank. Bank will notify Borrower when it debits
Borrower's accounts. These debits are not a set-off. Payments received after

5      REPRESENTATIONS AND WARRANTIES
       ------------------------------

       Borrower represents and warrants as follows:

5.1    DUE ORGANIZATION AND AUTHORIZATION.

standing in, any state in which the conduct of its business or its ownership of
property requires that it be qualified.

       The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's formation documents, nor

bound.  Borrower is not in default under any agreement to which or by which it
is bound in which the default could cause a Material Adverse Change.

5.2    COLLATERAL.

5.3    LITIGATION.

       Except as shown in the Schedule, there are no actions or proceedings
pending or, to Borrower's knowledge, threatened by or against Borrower or any
Subsidiary in which an adverse decision could cause a Material Adverse Change
other than regulatory proceedings with the FDA and European governmental
authorities relating to the approval of Borrower's products.

5.4    NO MATERIAL ADVERSE CHANGE IN FINANCIAL STATEMENTS.

       All consolidated financial statements for Borrower, and any Subsidiary,

consolidated financial condition since the date of the most recent financial
statements submitted to Bank.

5.5    SOLVENCY.

       The fair salable value of Borrower's assets (including goodwill minus
disposition costs) exceeds the fair value of its liabilities; the Borrower is

       If Borrower fails to pay any of the Obligations when due;


                                       7
<PAGE>
 
8.2    COVENANT DEFAULT.

       If Borrower does not perform any obligation in Section 6 or violates any
covenant in Section 7 or does not perform or observe any other material term,
condition or covenant in this Agreement, any Loan Documents, or in any agreement
between Borrower and Bank and as to any default under a term, condition or
covenant that can be cured, has not cured the default within 10 days after it
occurs, or if the default cannot be cured within 10 days or cannot be cured
after Borrower's attempts within 10 day period, and the default may be cured
within a reasonable time, then Borrower has an additional period (of not more
than 30 days) to attempt to cure the default.  During the additional time, the
failure to cure the default is not an Event of Default (but no Credit Extensions
will be made during the cure period);

8.3    MATERIAL ADVERSE CHANGE.

        (i)   If there occurs a material impairment in the perfection or
priority of the Bank's security interest in the Collateral or in the value of
such Collateral which is not covered by adequate insurance or (ii) if the Bank
determines, based upon information available to it and in its reasonable
judgment, that it is reasonably foreseeable that Borrower will fail to comply
with one or more of the financial covenants in Section 6 during the next
succeeding financial reporting period (a "Material Adverse Change").

8.4    ATTACHMENT.

       If any material portion of Borrower's assets is attached, seized, levied
on, or comes into possession of a trustee or receiver and the attachment,
seizure or levy is not removed in 10 days, or if Borrower is enjoined,
restrained, or prevented by court order from conducting a material part of its
business or if a judgment or other claim becomes a Lien on a material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed against
any of Borrower's assets by any government agency and not paid within 10 days
after Borrower receives notice.  These are not Events of Default if stayed or if
a bond is posted pending contest by Borrower (but no Credit Extensions will be
made during the cure period);

8.5    INSOLVENCY.

       If Borrower becomes insolvent or if Borrower begins an Insolvency
Proceeding or an Insolvency Proceeding is begun against Borrower and not
dismissed or stayed within 60 days (but no Credit Extensions will be made before
any Insolvency Proceeding is dismissed);

9      BANK'S RIGHTS AND REMEDIES
       --------------------------

9.1    RIGHTS AND REMEDIES.

       While an Event of Default occurs and continues Bank may, without notice
or demand, do any or all of the following:

       (a)  Declare all Obligations immediately due and payable (but if an Event
of Default described in Section 8.5 occurs all Obligations are immediately due
and payable without any action by Bank);

       (b)  Stop advancing money or extending credit for Borrower's benefit
under this Agreement or under any other agreement between Borrower and Bank;

       (c)  Settle or adjust disputes and claims directly with account debtors
for amounts, on terms and in any order that Bank considers advisable;

       (d)  Make any payments and do any acts it considers necessary or
reasonable to protect its security interest in the Collateral. Borrower will
assemble the Collateral if Bank requires and make it available as Bank
designates. Bank may enter premises where the Collateral is located, take and
maintain possession of any part of the Collateral, and pay, purchase, contest,
or compromise any Lien which appears to be prior or superior to its security
interest and pay all expenses incurred. Borrower grants Bank a license to enter
and occupy any of its premises, without charge, to exercise any of Bank's rights
or remedies;

       (e)  Apply to the Obligations any (i) balances and deposits of Borrower
it holds, or (ii) any amount held by Bank owing to or for the credit or the
account of Borrower;

       (f)  Ship, reclaim, recover, store, finish, maintain, repair, prepare for
sale, advertise for sale, and sell the Collateral; and

       (g)  Dispose of the Collateral according to the Code.

9.2    POWER OF ATTORNEY.

       Effective only while an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to:  (i) endorse Borrower's
name on any checks or other forms of payment or security; (ii) sign Borrower's
name on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust disputes and claims about the Accounts directly
with account debtors, for amounts and on terms Bank determines reasonable; and
(v) transfer the Collateral into the name of Bank or a third party as the Code
permits.  Bank may exercise the power of attorney to sign Borrower's name on any
documents necessary to perfect or continue the perfection of any security
interest regardless of whether an Event of Default has occurred.  Bank's
appointment as Borrower's attorney in fact, and all of Bank's rights and powers,
coupled with an interest, are irrevocable until all Obligations have been fully
repaid and performed and Bank's obligation to provide Credit Extensions
terminates.

9.3    ACCOUNTS COLLECTION.

       While an Event of Default occurs and continues, Bank may notify any
Person owing Borrower money of Bank's security interest in the funds and verify
the amount of the Account, and Borrower must collect all payments in trust for
Bank and, if requested by Bank, immediately deliver the payments to Bank in the
form received from the account debtor, with proper endorsements for deposit.


                                       9
<PAGE>
 
9.4    BANK EXPENSES.

       If Borrower fails to pay any amount or furnish any required proof of
payment to third persons Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent.  Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral.  No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

9.5    BANK'S LIABILITY FOR COLLATERAL.

       If Bank complies with reasonable banking practices, it is not liable for:
(a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral;
(c) any diminution in the value of the Collateral; or (d) any act or default of
any carrier, warehouseman, bailee, or other person.  Borrower bears all risk of
loss, damage or destruction of the Collateral.

9.6    REMEDIES CUMULATIVE.

       Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative.  Bank has all rights and remedies provided
under the Code, by law, or in equity. Bank's exercise of one right or remedy is
not an election, and Bank's waiver of any Event of Default is not a continuing
waiver. Bank's delay is not a waiver, election, or acquiescence. No waiver is
effective unless signed by Bank and then is only effective for the specific
instance and purpose for which it was given.

9.7    DEMAND WAIVER.

       Borrower waives demand, notice of default or dishonor, notice of payment
and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

related agreement must be in writing and be personally delivered or sent by an
overnight delivery service, by certified mail, postage prepaid, return receipt

this Agreement.  A Party may change its notice address by giving the other Party

11     CHOICE OF LAW , VENUE AND JURY TRIAL WAIVER
       -------------------------------------------

       California law governs the Loan Documents without regard to principles of
conflicts of law.  Borrower and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in Santa Clara County, California.

BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE
OF ACTION ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY CONTEMPLATED
TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS
WAIVER IS A MATERIAL INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT.

       "PREPAYMENT FEE" is a fee on any portion of the Obligations with a fixed
interest rate (the "Fixed Obligations") paid before the payment due date.  "Base
Interest Rate" means Bank's initial cost of funding the Fixed Obligations.  The
Prepayment Fee is calculated as follows: First Bank determines a "Current Market
Rate" based on what the Bank would receive if it loaned the amount on the
prepayment date in a wholesale funding market matching maturity, principal
amount and principal and interest payment dates (the aggregate payments received
are the "Current Market Rate Amount").  Bank may select any wholesale funding
market rate as the Current Market Rate.  Second, Bank will take the prepayment
amount and calculate the present value of each principal and interest payment
which, without prepayment, the Bank would have received during the term of the
Fixed Obligations using the Base Interest Rate.  The sum of the present value
calculations is the "Mark to Market Amount."  Third, the Bank will subtract the
Mark to market Amount from the Current Market Rate Amount.  Any amount greater
than zero is the Prepayment Fee.

       "PRIME RATE" is Bank's most recently announced "prime rate," even if it
is not Bank's lowest rate.

       "REMAINING MONTHS LIQUIDITY" is defined in Section 6.7.

       "RESPONSIBLE OFFICER" is each of the Chief Executive Officer, the
President, the Chief Financial Officer and the Controller of Borrower.

      "SCHEDULE" is any attached schedule of exceptions.


                                      15
<PAGE>
 
       "SUBORDINATED DEBT" is debt incurred by Borrower subordinated to
Borrower's debt to Bank (and identified as subordinated by Borrower and Bank).

       "SUBSIDIARY" is for any Person, or any other business entity of which
more than 50% of the voting stock or other equity interests is owned or
controlled, directly or indirectly, by the Person or one or more Affiliates of
the Person.

       "TANGIBLE NET WORTH" is, on any date, the consolidated total assets of
Borrower and its Subsidiaries minus, (i) any amounts attributable to (a)
                              -----                                     
goodwill, (b) intangible items such as unamortized debt discount and expense,
Patents, trade and service marks and names, Copyrights and research and
development expenses except prepaid expenses, and (c) reserves not already
deducted from assets, and (ii) Total Liabilities, plus Subordinated Debt (less
                      ---                                                     
the current portion of such Subordinated Debt allowed to be paid).

       "TOTAL LIABILITIES" is on any day, obligations that should, under GAAP,
be classified as liabilities on Borrower's consolidated balance sheet, including
all Indebtedness, and current portion Subordinated Debt allowed to be paid, but
excluding all other Subordinated Debt.

       "TREASURY NOTE RATE"  is a Treasury Yield Percentage.  Treasury Yield
Percentage is the average weekly yield (of the week ending figures) in the most
recent Federal Reserve Statistical Release on actively traded U.S. Treasury
obligations of similar maturity to the principal being repaid or if a
Statistical Release is not published, the arithmetic average (to the nearest
 .01%) of the per annum yields to maturity for each Business Day during the week
(ending at least two Business Days before the determination is made) of all
actively traded marketable United States Treasury fixed interest rate securities
with a constant maturity of, or not more than 30 days longer or shorter than the
average life of the principal and interest payments that are being prepaid
(excluding securities that can be surrendered at face value to pay Federal
estate tax, or which provide for tax benefits to the holder).

       "UNRESTRICTED CASH RESERVES" is, at any time of determination, the sum of
Borrower's (i) cash balance of deposit accounts and investment accounts, plus
(ii) market value of all readily marketable securities beneficially owned by
Borrower, minus (iii) cash value of any certificates of deposit or securities
encumbered and/or restricted by any Bank or any other Persons.
