Prospectus Supplement dated April 21, 1997
to Prospectus dated February 3, 1997


                                  VIDAMED, INC.

                         404,040 Shares of Common Stock
                    40,404 Warrants to Purchase Common Stock

         VidaMed,  Inc.  ("VidaMed" or the "Company") is offering hereby 404,040
shares of its Common Stock, $.001 par value (the "Common Stock") and warrants to
purchase  40,404 shares of Common Stock.  The offering price per share of Common
Stock is $6.6161 per share.  The exercise  price for the Warrants is $9.1890 per
share.

Sale of Securities

         In  February  1997,  the  Company  entered  into  an  equity  financing
arrangement with a European  investment bank under which the Company may, at its
option, sell to such investment bank up to $10.0 million of VidaMed Common Stock
in increments  of up to $2.5  million.  The Common Stock will be priced at a 10%
discount to the current market price at the time of sale,  subject to adjustment
based on a formula  linked to the market  price of the  Company's  Common  Stock
during the twenty-one  (21) trading days following  each sale.  Concurrent  with
each stock  issuance,  the Company will issue to the investment bank Warrants to
purchase  one  share of Common  Stock  for each 10  shares  of  Common  Stock so
purchased.  The exercise  price for such  Warrants will be equal to the adjusted
purchase  price for the Common Stock  multiplied  by 1/0.9,  with the  resulting
product  multiplied by 1.25.  Such warrants will have a term of three years from
the date of issuance. In connection with this arrangement, the Company paid such
European investment bank a commitment fee of $100,000.

         On March 12, 1997,  the Company  issued  286,123 shares of Common Stock
and   warrants   to   purchase   28,613   shares  of  Common   Stock  under  the
above-referenced  equity  financing  arrangement.  The 404,040  shares of Common
Stock and the warrants to purchase  40,404 shares of Common Stock offered hereby
represent the second  issuance of securities by the Company under such financing
arrangement.

         The Company has not entered  into any  underwriting  arrangements  with
respect to the shares of Common Stock or Warrants.

         The Common  Stock is quoted on the  Nasdaq  National  Market  under the
symbol VIDA. The Warrants are not quoted or listed on any securities exchange or
market,  and the Company does not intend to apply for listing of the Warrants on
any securities exchange or market.  Accordingly, no public market exists for the
Warrants and it is not expected that any such market will exist in the future.

Certain Federal Income Tax Consequences

         The following is a discussion of certain  United States  federal income
and estate tax consequences of the ownership and disposition of the Common Stock
applicable  to Non-U.S.  Holders of such Common Stock.  In general,  a "Non-U.S.
Holder" is any owner of Common Stock other than (i) a citizen or resident of the
United  States,  or  certain  United  States  expatriates,  (ii) a  corporation,
partnership  or other entity  created or organized in the United States or under
the laws of the United States or of any state, or (iii) an estate or trust whose
income is  includible  in gross  income for  United  States  federal  income tax
purposes  regardless of its source. The discussion pertains only to Common Stock
held as a "capital  asset" as defined in the Internal  Revenue Code of 1986,  as
amended (the "Code"). The discussion is based on laws, regulations,  rulings and
decisions in effect on the date hereof,  all of which are subject to change. The
discussion  does not address  aspects of taxation  other than federal income and
estate  taxation  and does not address all aspects of federal  income and estate
taxation.  The discussion is for general  information only and does not consider
any specific  facts or  circumstances  that may apply to a  particular  Non-U.S.
Holder.  Accordingly,  prospective  investors are urged to consult their own tax
advisors  regarding the United States  federal,  state,  local and non-U.S.  tax
consequences of acquiring, holding and disposing of shares of Common Stock.

         Dividends

         In  general,  dividends  paid to a Non-U.S.  Holder  will be subject to
United States withholding tax at a 30% rate (or such lower rate prescribed by an
applicable tax treaty) unless the dividends are either (i) effectively connected
with a trade or business  carried on by the  Non-U.S.  Holder  within the United
States,  or  (ii) if a tax  treaty  applies,  attributable  to a  United  States
permanent establishment maintained by the Non-U.S. Holder. Dividends effectively
connected  with  such  trade  or  business  or  attributable  to such  permanent
establishment  (provided a tax treaty applies)  generally will not be subject to
withholding  (if the Non-U.S.  Holder files  certain forms with the payor of the
dividend) and generally will be subject to United States federal income tax on a
net income basis at the applicable graduated rates. In addition,  in the case of
a Non-U.S.  Holder  that is a  corporation,  a U.S.  branch  profits  tax may be
imposed on such  corporation's  effectively  connected  earnings and profits (as
determined  under the Code).  The branch profits tax is imposed at a rate of 30%
(or such lower rate  prescribed by an applicable  tax treaty).  To determine the
applicability  of a tax  treaty  providing  for a  lower  rate  of  withholding,
dividends paid to an address in a foreign country are presumed under the current
interpretation of existing Treasury regulations to be paid to a resident of that
country.

         Treasury  regulations  proposed  in 1984  which  have not been  finally
adopted,  however,  would require Non-U.S.  Holders to file certain new forms to
obtain the benefit of any  applicable  tax treaty  providing for a lower rate of
withholding  tax on  dividends.  Such forms would  contain the holder's name and
address and an official  statement  by the  competent  authority  in the foreign
country (as designated in the  applicable tax treaty)  attesting to the holder's
status as a resident thereof.


<PAGE>

         Sale of Common Stock

         Generally,  a Non-U.S.  Holder  will not be  subject  to United  States
federal  income tax on any gain upon the  disposition of his Common Stock unless
(i) the Company is or has been a "U.S. real property  holding  corporation"  for
federal income tax purposes (which the Company does not believe that it is or is
likely  to  become),  (ii) the  gain is  effectively  connected  with a trade or
business carried on by the Non-U.S. Holder within the United States or, if a tax
treaty  applies,  attributable  to a permanent  establishment  maintained by the
Non-U.S.  Holder  in the  United  States,  or (iii)  the  Non-U.S.  Holder is an
individual  who is  present  in the  United  States  for 183 days or more in the
taxable year of the  disposition,  and either (a) the Non-U.S.  Holder has a tax
home (as specially  defined for U.S.  federal income tax purposes) in the United
States and the gain from the  disposition  is not  attributable  to an office or
other fixed place of business  maintained  by the  Non-U.S.  Holder in a foreign
country or (b) the gain from the  disposition  is  attributable  to an office or
other fixed place of business  maintained  in the United  States by the Non-U.S.
Holder.

         Estate Tax

         In general,  Common  Stock  owned or treated as owned by an  individual
Non-U.S.  Holder will be includible in the individual's  gross estate for United
States  federal estate tax purposes,  unless an applicable  tax treaty  provides
otherwise.

         Backup Withholding and Information Reporting

         The Company must report annually to the Internal Revenue Service and to
each Non-U.S.  Holder the amount of dividends paid to, and the tax withheld with
respect to, each Non-U.S. Holder. These information reporting requirements apply
regardless of whether withholding was reduced or eliminated by an applicable tax
treaty. Copies of these information returns may also be made available under the
provisions  of a specific  treaty or  agreement  to the tax  authorities  in the
country in which the Non-U.S.  Holder resides.  United States backup withholding
tax (which  generally is a withholding tax imposed at the rate of 31% on certain
payments to persons  that fail to furnish  the  information  required  under the
United States  information  reporting or backup  withholding  requirements) will
generally not apply to dividends paid on Common Stock to a Non-U.S. Holder at an
address outside the United States.

         The  payment of proceeds  from the  disposition  of Common  Stock by or
through a foreign  office of a foreign  broker  generally will not be subject to
backup  withholding or  information  reporting.  Information  reporting (but not
backup  withholding)  will apply,  however,  to the payment of proceeds from the
disposition  of Common  Stock by or through the  foreign  office of (i) a United
States  broker,  (ii) a broker that  derives 50% or more of its gross income for
certain periods from the conduct of a trade or business in the United States, or
(iii) a broker that is a  "controlled  foreign  corporation"  for United  States
federal income tax purposes,  unless the broker has documentary  evidence in its
records that the owner is a Non-U.S. Holder and certain other conditions are met
or the owner  otherwise  establishes an exemption.  The payment of proceeds from
the disposition of Common Stock by or through a United States office of a broker
will be subject to both backup withholding and information  reporting unless the
owner  certifies  under  penalty of perjury that,  among other  things,  it is a
Non-U.S. Holder or otherwise establishes an exemption.

                                   THE COMPANY

         VidaMed, Inc. (the "Company" or "VidaMed") was founded in July 1992 and
reincorporated in the State of Delaware in June 1995. VidaMed designs, develops,
manufactures and markets technologically and clinically advanced, cost effective
systems for  urological  applications.  The Company's  initial focus is upon the
treatment of benign prostatic  hyperplasia ("BPH"). The Company's first product,
the  patented  TUNA  System,  is designed to offer a cost  effective,  minimally
invasive  alternative  therapy  with  compelling  clinical  advantages  for  BPH
treatment.  The Company commenced manufacturing  production and product sales in
1993. On October 8, 1996, the Company  received 510(k) clearance from the United
States  Food  and  Drug  Administration   ("FDA")  to  market  the  TUNA  System
commercially  in the  United  States  for the  treatment  of BPH.  In the United
States,  the Company sells its products primarily through direct sales personnel
and a network of specialty  urology  product  dealers.  International  sales are
primarily to distributors who resell to physicians and hospitals.

         VidaMed has designed and developed the TUNA System to be the therapy of
choice  for BPH  over  watchful  waiting,  drug  therapy  and  current  surgical
therapies. The TUNA System is designed to restore and improve urinary flow while
resulting in fewer complications and adverse effects,  shorter recovery time and
greater cost  effectiveness  than other  therapies for treating BPH. The Company
believes that the cost of treatment with TUNA will be less than the cost of many
other  interventional  BPH  therapies  because the  procedure  is designed to be
performed on an outpatient basis and to result in fewer complications.

         The principal components of the TUNA system are (i) a single-use needle
ablation  catheter that delivers RF energy to the prostate,  (ii) a low power RF
energy  generator and (iii) an optical  device that allows direct viewing during
the procedure.

         TUNA  Catheter.   The  single-use  TUNA  catheter  measures  22  French
(approximately  seven  millimeters) in diameter and contains  laterally deployed
needles that extend at an approximately 90 degree angle.  Each needle is encased
by a  retractable  shield  which  protects  the  urethra  and is adjusted by the
urologist to selectively  control the area of prostate tissue ablated during the
procedure. Controls on the catheter handle allow for independent advancement and
retraction  of the needle and shields.  Thermocouples  located at the shield tip
and at the  catheter  tip  record  temperatures  at the  lesion  site and in the
prostatic  urethra.  The  catheter  includes  capabilities  for  irrigation  and
aspiration,  enhancing  visualization for the physician and enabling drainage of
the bladder without  removing and reinserting the catheter.  In addition,  these
capabilities  allow  the  physician  to more  closely  control  urethral  tissue
temperature during the procedure.

         TUNA  RF   Generator.   The  TUNA  RF  energy   generator  is  designed
specifically  for use with the  TUNA  catheter.  The RF  generator  has  digital
displays  indicating the  temperature at each  thermocouple,  the RF power being
delivered  to  each  needle,  ablation  time  and  electrical  impedance.  These
measurements are used by the physician to control tissue ablation. The generator
incorporates  both  automated  and manual  control  modes.  The generator has an
automatic shut-off  activated by both temperature and impedance  measurements to
ensure controlled tissue ablation.

         TUNA Optics. The TUNA optical device allows precise  positioning of the
catheter  between the  verumontanum  and the bladder  neck during the  procedure
using direct vision control.  The optical device is reusable after sterilization
and is equipped with a three-way  exchange adapter,  which allows the unit to be
used with endoscopic light sources manufactured by other companies.

         The TUNA procedure  desiccates  prostatic  tissue,  leading to improved
urinary flow, and can be performed in  approximately 30 to 45 minutes with local
anesthesia, which may be supplemented by intravenous sedation. The TUNA catheter
is inserted into the patient's  urethra,  and the two shielded needle electrodes
are then advanced into


                                       -4-

<PAGE>


one of the two lateral lobes of the prostate.  Controlled RF energy delivered by
the  needle   electrodes  heats  targeted  portions  of  the  prostate  lobe  to
temperatures  of 90 to 100  degrees  centigrade,  creating a  localized  area of
desiccated  tissue measuring  approximately  one to two centimeters in diameter,
while the shields  protect the urethra  from  thermal  damage.  Once a lesion of
sufficient size has been created,  the urologist retracts the needles and places
the catheter at the next site to be ablated and repeats the process.  Typically,
two  treatments in each lateral  prostate lobe are performed  depending upon the
size of the  prostate.  If the  patient  is unable to urinate  due to  temporary
swelling or  irritation  of the urethra,  a catheter  will be inserted  into the
patient's urethra.  This catheter,  if inserted,  is typically left in place for
one to two days.

         The  Company  believes  that  the  design  of the  TUNA  system  offers
significant advantages over other BPH therapies. Because the TUNA system shields
the urethra and delivers  controlled RF energy directly into the interior of the
prostate,  the procedure  protects the prostatic urethra and reduces the risk of
unintended thermal damage to surrounding  structures.  In other procedures where
this control does not exist,  the prostatic  urethra and other structures can be
damaged or destroyed,  causing significant patient discomfort and complications.
Clinical  trials of the TUNA system  indicate  that TUNA results in fewer of the
complications associated with TURP, including impotence,  retrograde ejaculation
and  incontinence.  The Company  believes that the cost of the TUNA procedure in
the United States,  including physician charges, will be significantly less than
the cost of TURP.  Based on  information  received  from its  distributors,  the
Company  believes  that the TUNA RF  generator  is sold at prices  ranging  from
$20,000 to $35,000,  which is less than the general  surgical lasers required to
perform laser  procedures and the ultrasound and microwave  devices required for
other surgical procedures.

         The Company  believes TUNA will also provide  patients,  physicians and
health care payors with a clinically and  economically  superior  alternative to
ongoing drug therapy and  watchful  waiting.  To date,  the  symptomatic  relief
experienced by patients in the Company's  clinical trials suggests that TUNA may
provide  greater  relief  than drug  therapy or  watchful  waiting.  The Company
believes  that if the relief  provided  by TUNA proves to be  sufficiently  long
lasting,  TUNA  may  prove  to  be  economically  superior  to  the  noninvasive
approaches.  To date, the Company's  available  two-year clinical follow-up data
for TUNA  patients  do not  suggest  the need for  retreatment  within this time
frame. However,  there can be no assurance as to whether and how frequently TUNA
patients will require retreatment.


                               RECENT DEVELOPMENTS

         On October 8, 1996, the Company  received 510(k) clearance from the FDA
to market the TUNA System for the  treatment of BPH  commercially  in the United
States.  The FDA's clearance of the TUNA System was based on studies of the TUNA
System's safety and clinical efficacy which were conducted in the United States.
As a result of the 510(k) clearance,  the Company commenced  commercial sales in
October 1996 and expanded its dealer network.


                                  RISK FACTORS

         An  investment  in the  Securities  being  offered  by this  Prospectus
involves a high  degree of risk.  The  following  factors,  in addition to those
discussed  elsewhere  in this  Prospectus,  should be  carefully  considered  in
evaluating the Company and its business  prospects before purchasing  Securities
offered by this Prospectus.

         Limited Operating History;  History of Losses and Expectation of Future
Losses;  Fluctuations in Operating Results. The Company has a limited history of
operations.  Since its  inception in July 1992,  the Company has been  primarily
engaged  in  research  and  development  of the TUNA  system.  The  Company  has
experienced  significant  operating  losses since inception and, as of September
30, 1996, had an accumulated deficit of $48.8

                                       -5-

<PAGE>


million. The development and commercialization by the Company of the TUNA system
and other new products,  if any, will require substantial  product  development,
clinical, regulatory,  marketing and other expenditures. The Company expects its
operating  losses  to  continue  for at  least  the next 12 to 18  months  as it
continues to expend substantial  resources in funding clinical trials in support
of  regulatory  and  reimbursement  approvals,  expansion of marketing and sales
activities and research and development. There can be no assurance that the TUNA
system 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. Results of operations may fluctuate significantly from quarter to
quarter and will depend upon numerous  factors,  including  actions  relating to
regulatory and reimbursement matters, progress of clinical trials, the extent to
which the TUNA system gains market  acceptance,  varying pricing  promotions and
volume discounts to distributors,  introduction of alternative therapies for BPH
and competition.

         Uncertainty  of Market  Acceptance.  TUNA  represents a new therapy for
BPH,  and  there  can be no  assurance  that  the  TUNA  system  will  gain  any
significant  degree of market acceptance among  physicians,  patients and health
care payors,  even if necessary  international  and United States  reimbursement
approvals are obtained.  Physicians will not recommend the TUNA procedure unless
they  conclude,  based  on  clinical  data  and  other  factors,  that  it is an
attractive  alternative  to  other  methods  of BPH  treatment,  including  more
established methods such as TURP and drug therapy. In particular, physicians may
elect not to  recommend  the TUNA  procedure  until  such time,  if any,  as the
duration of the relief provided by the procedure has been established. Broad use
of the TUNA system will  require the  training of numerous  physicians,  and the
time required to complete such training  could result in a delay or dampening of
market  acceptance.  Even if the  clinical  efficacy  of the TUNA  procedure  is
established,  physicians  may  elect  not  to  recommend  the  procedure  unless
acceptable reimbursement from health care payors is available. Health care payor
acceptance of the TUNA procedure will require evidence of the cost effectiveness
of TUNA as compared to other BPH  therapies,  which will depend in large part on
the duration of the relief provided by the TUNA procedure.  A thorough  analysis
of multi-year  patient follow-up data will be necessary to assess the durability
of the relief provided by TUNA therapy. Patient acceptance of the procedure will
depend in part on physician recommendations as well as other factors,  including
the degree of  invasiveness  and rate and severity of  complications  associated
with the procedure as compared to other therapies.

         Uncertainty  Relating  to  Third  Party  Reimbursement.  The  Company's
success  will be  dependent  upon,  among  other  things,  its ability to obtain
satisfactory  reimbursement  from health care payors for the TUNA procedure.  In
the United States and in  international  markets,  third party  reimbursement is
generally  available  for existing  therapies  used for treatment of BPH. In the
United  States,  third  party  reimbursement  for  the  TUNA  procedure  will be
dependent upon decisions by the Health Care  Financing  Administration  ("HCFA")
for Medicare, as well as by individual health maintenance organizations, private
insurers and other payors.

         Reimbursement  systems in international  markets vary  significantly by
country.  Many  international  markets have  governmentally  managed health care
systems  that  govern  reimbursement  for new devices  and  procedures.  In most
markets,  there are private insurance systems as well as governmentally  managed
systems.

         Regardless of the type of  reimbursement  system,  the Company believes
that  physician  advocacy  of  the  TUNA  system  will  be  required  to  obtain
reimbursement.  Availability  of  reimbursement  will  depend  not  only  on the
clinical  efficacy  and  direct  cost of the  TUNA  procedure,  but  also on the
duration of the relief provided by the procedure. There can be no assurance that
reimbursement for the Company's  products will be available in the United States
or in international  markets under either governmental or private  reimbursement
systems,  or that physicians  will support  reimbursement  for TUNA  procedures.
Furthermore, the Company could be adversely affected by changes in reimbursement
policies of governmental  or private health care payors.  Failure by physicians,
hospitals  and  other  users of the  Company's  products  to  obtain  sufficient
reimbursement from health care payors or adverse changes in


                                       -6-

<PAGE>


governmental and private third party payors' policies toward  reimbursement  for
procedures employing the Company's products would have a material adverse effect
on the Company's business, financial condition and results of operations.

         Risk of  Inadequate  Funding.  The Company  plans to continue to expend
substantial funds for clinical trials in support of regulatory and reimbursement
approvals, expansion of sales and marketing activities, research and development
and establishment of commercial scale manufacturing capability.  The Company may
be required to expend greater than anticipated funds if unforeseen  difficulties
arise in the course of clinical  trials of the TUNA system,  in connection  with
obtaining necessary  regulatory and reimbursement  approvals or in other aspects
of the Company's  business.  Although the Company  believes that the proceeds of
the offering of the Securities together with its existing cash reserves and cash
generated  from the  future  sale of  products  will be  sufficient  to meet the
Company's  operating and capital  requirements  during the next 12 to 24 months,
there can be no assurance that the Company will not require additional financing
within this time frame. The Company's future liquidity and capital  requirements
will depend  upon  numerous  factors,  including  progress  of clinical  trials,
actions  relating to regulatory  and  reimbursement  matters,  and the extent to
which the TUNA system gains market  acceptance.  Any  additional  financing,  if
required,  may not be available on  satisfactory  terms or at all. Future equity
financings may result in dilution to the holders of the Company's Common Stock.

         Possible  Volatility of Stock Price.  The stock market has from time to
time experienced significant price and volume fluctuations that are unrelated to
the  operating   performance  of  particular   companies.   These  broad  market
fluctuations  may  adversely  affect the market  price of the  Company's  Common
Stock. In addition,  the market price of the shares of Common Stock is likely to
be highly  volatile.  Factors such as  fluctuations  in the Company's  operating
results,  announcements  of  technological  innovations  or new  products by the
Company or its competitors,  FDA and international  regulatory actions,  actions
with respect to reimbursement  matters,  developments with respect to patents or
proprietary rights, public concern as to the safety of products developed by the
Company  or  others,  changes in health  care  policy in the  United  States and
internationally,  changes in stock market analyst recommendations  regarding the
Company, other medical device companies or the medical device industry generally
and general market conditions may have a significant  effect on the market price
of the Common Stock.

         Competition and Technological  Advances.  Competition in the market for
treatment  of BPH is intense and is expected to increase.  The Company  believes
its principal  competition will come from invasive therapies,  such as TURP, and
noninvasive  courses of action,  such as drug therapy and watchful waiting.  The
Company may encounter competition from emerging therapies in attracting clinical
investigators  as well  as  prospective  clinical  trial  patients.  Most of the
Company's competitors have significantly greater financial, technical, research,
marketing,  sales,  distribution and other resources than the Company. There can
be no assurance that the Company's competitors will not succeed in developing or
marketing  technologies  and products  that are more  effective or  commercially
attractive than any which are being developed by the Company.  Such developments
could  have a  material  adverse  effect on the  Company's  business,  financial
condition and results of operations.

         Any product  developed  by the Company that gains  regulatory  approval
will have to compete for market acceptance and market share. An important factor
in such  competition  may be the timing of market  introduction  of  competitive
products.  Accordingly,  the  relative  speed with which the Company can develop
products,  complete  clinical testing and regulatory  approval  processes,  gain
reimbursement  acceptance and supply commercial quantities of the product to the
market are expected to be important  competitive  factors.  The Company  expects
that competition in the BPH field will also be based, among other things, on the
ability of the therapy to provide safe,  effective and lasting  treatment,  cost
effectiveness  of  the  therapy,   physician,  health  care  payor  and  patient
acceptance of the procedure,  patent position,  marketing and sales  capability,
and third party reimbursement policies.

         Government  Regulation.  The Company's  TUNA system is regulated in the
United States as a medical  device by the FDA under the Federal Food,  Drug, and
Cosmetic  Act  ("FDC  Act").  Pursuant  to the FDC Act,  the FDA  regulates  the
manufacture,  distribution  and  production  of  medical  devices  in the United
States.   Noncompliance  with  applicable  requirements  can  result  in  fines,
injunctions,  civil penalties,  recall or seizure of products,  total or partial
suspension  of  production,  failure of the  government  to grant  approval  for
devices,  and criminal  prosecution.  Medical devices are classified into one of
three  classes,  class I, II or III, on the basis of the  controls  necessary to
reasonably ensure their safety and  effectiveness.  The safety and effectiveness
can be assured for class I devices  through general  controls  (e.g.,  labeling,
premarket  notification  and adherence to GMPs) and for class II devices through
the  use  of  special   controls  (e.g.,   performance   standards,   postmarket
surveillance,  patient  registries,  and FDA guidelines).  Generally,  class III
devices are those  which must  receive  premarket  approval by the FDA to ensure
their  safety and  effectiveness  (e.g.,  life-sustaining,  life-supporting  and
implantable  devices,  or new  devices  which have not been found  substantially
equivalent to legally marketed devices).

         Before a new device can be introduced into the market, the manufacturer
must generally  obtain FDA clearance  through either a 510(k)  notification or a
premarket  approval ("PMA"). A 510(k) clearance will be granted if the submitted
data  establishes  that the proposed device is  "substantially  equivalent" to a
legally marketed class I or II medical device,  or to a class III medical device
for which the FDA has not called for a PMA. The FDA has recently been  requiring
a more rigorous  demonstration  of substantial  equivalence than in the past. It
generally  takes from three to nine  months from  submission  to obtain a 510(k)
clearance,  but it may take  longer.  The FDA may  determine  that the  proposed
device is not substantially equivalent, or that additional data is needed before
a  substantial  equivalence  determination  can be  made.  A "not  substantially
equivalent"  determination,  or a request for additional  data,  could delay the
market  introduction of new products that fall into this category and could have
a materially adverse effect on the Company's  business,  financial condition and
results of  operations.  There can be no assurance  that the Company will obtain
510(k)  clearance  within the above time  frames,  if at all, for any device for
which  it files a  future  510(k)  notification.  Furthermore,  there  can be no
assurance that the Company will not be required to submit a PMA  application for
any device which it may develop in the future. For any of the Company's products
that are cleared  through  the 510(k)  process,  including  the  Company's  TUNA
System,  modifications or enhancements that could significantly affect safety or
efficacy will require new 510(k) submissions.

         Sales of  medical  devices  outside  the United  States are  subject to
regulatory  requirements  that vary  widely from  country to  country.  The time
required  to  obtain  approval  for sale in a foreign  country  may be longer or
shorter than that required for FDA approval,  and the  requirements  may differ.
VidaMed has received regulatory  approvals where required for commercial sale of
the TUNA system in all major  international  markets,  except Japan. In May 1994
the Company's  United Kingdom  facility passed  inspection by the United Kingdom
Department of Health and received GMP  certification.  In June 1994, the Company
received a report of compliance  for the TUNA system from the British  Standards
Institute  ("BSI")  and in August  1994 the Company  received a  certificate  of
compliance with IEC 601-1 and IEC 601-2  regulations from TUV Product  Services.
TUV and BSI  certifications,  which are  issued by  organizations  analogous  to
Underwriters Laboratories in the United States, are focused on device safety and
adherence of the device to published electronic or mechanical specifications. In
February 1995, the Company received ISO 9002 certification for its manufacturing
facility in the United Kingdom.  ISO 9002 certification is based on adherence to
established  standards  in the  areas of  quality  assurance  and  manufacturing
process control.  These certifications allow the Company to affix the CE mark to
the TUNA system, permitting the Company to commercially market and sell the TUNA
system in all  countries of the  European  Economic  Area.  In order to maintain
these  approvals,  the  Company is subject to periodic  inspections.  Additional
product  approvals  from  foreign  regulatory  authorities  may be required  for
international sale of the Company's general  electrosurgical device for which an
FDA  510(k)  notification  has been  filed.  Failure to comply  with  applicable
regulatory  requirements can result in loss of previously received approvals and
other  sanctions  and could  have a  material  adverse  effect on the  Company's
business, financial condition and results of operations.

                                       -8-

<PAGE>


         The  Company's   distributor  in  Japan,   Century  Medical,   will  be
responsible for management of clinical trials and obtaining  regulatory approval
for the TUNA system,  and such approval will  therefore be outside the Company's
control.  Accordingly,  there can be no  assurance  as to when or  whether  such
approval will be received.

         Limited Manufacturing  Experience;  Scale-Up Risk; Product Recall Risk.
VidaMed purchases  components used in the TUNA system from various suppliers and
relies on single  sources for several  components.  Delays  associated  with any
future  component   shortages,   particularly  as  the  Company  scales  up  its
manufacturing  activities in support of commercial sales,  would have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

         The  Company   currently   manufactures  the  TUNA  system  in  limited
quantities  at its United  Kingdom  facility.  However,  the Company has limited
experience in manufacturing its products in commercial quantities. Manufacturers
often encounter difficulties in scaling up production of new products, including
problems involving production yields,  quality control and assurance,  component
supply and lack of qualified personnel.  Difficulties  encountered by VidaMed in
manufacturing  scale-up  could have a material  adverse  effect on its business,
financial  condition  and  results  of  operations.  In  mid-1994,  the  Company
experienced  problems at its United Kingdom  facility with respect to mechanical
aspects of the TUNA  catheter's  needle  assembly.  As a result,  a  substantial
portion of  catheters  in the field were  returned  for rework.  The Company has
modified its  manufacturing  process to rectify these problems and has completed
product  rework.  However,  there can be no assurance that future  manufacturing
difficulties or product  recalls,  either of which could have a material adverse
effect on the Company's business, financial condition and results of operations,
will not occur.

         Any products manufactured or distributed by the Company pursuant to FDA
clearances or approvals are subject to pervasive  and  continuing  regulation by
FDA including  recordkeeping  requirements  and reporting of adverse  experience
with the use of the device. The Company's  manufacturing  facilities are subject
to periodic  inspection by FDA,  certain state  agencies and foreign  regulatory
agencies.  Failure to comply with regulatory  requirements could have a material
adverse  effect on the Company's  business.  There can be no assurance  that the
Company will not be required to incur  significant costs to comply with laws and
regulations in the future or that laws or  regulations  will not have a material
adverse effect upon the Company's business.

         Uncertainty Regarding Patents and Protection of Proprietary Technology.
The  Company  has been  issued 25 United  States  patents  covering  a method of
prostate  ablation using the TUNA System and the design of the TUNA System.  The
Company currently has approximately 25 patent applications on file in the United
States and over 80 corresponding  patent applications on file in various foreign
countries. In addition, the Company holds licenses to certain technology used in
the TUNA System.  There can be no assurance  that the  Company's  issued  United
States patents,  or any patents which may be issued as a result of the Company's
applications,  will offer any degree of  protection.  There can be no  assurance
that any of the Company's patents or patent applications will not be challenged,
invalidated  or  circumvented  in  the  future.  In  addition,  there  can be no
assurance that  competitors,  many of which have substantial  resources and have
made substantial investments in competing  technologies,  will not seek to apply
for and obtain patents that will prevent,  limit or interfere with the Company's
ability to make,  use or sell its  products  either in the  United  States or in
international markets.

         Intellectual  Property  Litigation  Risks. The Company is aware that EP
Technologies,  Inc. ("EPT") and the University of California ("UC") have filed a
United States patent application in the field of ablation of body tissue.  These
parties  have also  requested  the United  States  Patent and  Trademark  Office
("USPTO") to declare an  interference  with a third party's issued United States
patent  relating  to the  ablation  of heart  tissue and with two United  States
patent  applications  of  VidaMed  on which  notices  of  allowances  have  been
received.


                                       -9-

<PAGE>


Interference   proceedings  are  declared  by  the  USPTO  for  the  purpose  of
determining which of the parties in the interference was the first to invent the
subject  matter of the  interference.  There can be no assurance  that the USPTO
will not declare an interference  involving  VidaMed or that, if declared,  such
interference will not be determined adversely to the Company. If an interference
proceeding were determined adversely to the Company, the Company's patent claims
that are the  subject  of the  interference  would not be issued  and the patent
claims  issued to the  prevailing  party  could cover  aspects of the  Company's
products and activities.  In addition,  there can be no assurance that the USPTO
will not use the prevailing party's  application to reject the allowed claims of
the Company.  The  enforcement of any such patent claims  against  VidaMed could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

         The  medical  device  industry  has  been  characterized  by  extensive
litigation  regarding  patents  and  other  intellectual  property  rights,  and
companies in the medical  device  industry have employed  intellectual  property
litigation to gain a competitive advantage. The Company is aware of patents held
by other  participants in the BPH market, and there can be no assurance that the
Company will not in the future become subject to patent  infringement claims and
litigation or USPTO interference proceedings, including an interference relating
to the EPT/UC application.  The defense and prosecution of intellectual property
suits,  USPTO  interference  proceedings  and related  legal and  administrative
proceedings are both costly and time  consuming.  Litigation 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. The Company, Mr. Edwards, who was a founder of
the Company and its former Chief Executive Officer,  and a co-founder and former
director of VidaMed settled,  in September 1995, a dispute with EPT relating to,
among  other  things,  certain  inventions  of  Mr.  Edwards.  Pursuant  to  the
settlement, mutual releases were granted.

         Any litigation or interference  proceedings could result in substantial
expense to the  Company and  significant  diversion  of effort by the  Company's
technical and management  personnel.  An adverse  determination in litigation or
interference  proceedings  to which the Company may become a party could subject
the Company to  significant  liabilities to third parties or require the Company
to seek licenses from third parties.  Although patent and intellectual  property
disputes in the medical device area have often been settled through licensing or
similar arrangements, costs associated with such arrangements may be substantial
and could include ongoing royalties. Furthermore, there can be no assurance that
necessary licenses would be available to the Company on satisfactory terms or at
all.  Accordingly,  an adverse  determination  in a judicial  or  administrative
proceeding  or failure to obtain  necessary  licenses  could prevent the Company
from manufacturing and selling its products, which would have a material adverse
effect on the Company's business, financial condition and results of operations.

         In  addition  to  patents,  the  Company  relies on trade  secrets  and
proprietary  know-how,  which it seeks to protect,  in part, through proprietary
information  agreements  with  employees,  consultants  and other  parties.  The
Company's proprietary  information agreements with its employees and consultants
contain industry standard provisions requiring such individuals to assign to the
Company without additional  consideration any inventions conceived or reduced to
practice by them while employed or retained by the Company, subject to customary
exceptions.  There can be no assurance that proprietary  information  agreements
with employees,  consultants  and others will not be breached,  that the Company
would have adequate remedies for any breach, or that the Company's trade secrets
will not otherwise become known to or independently developed by competitors.

         Rights to Founder's  Inventions  Limited to  Urology.  The  proprietary
information  agreement  between the Company  and Stuart D.  Edwards,  one of the
Company's  founders,  obligates  Mr.  Edwards  to  assign  to  the  Company  his
inventions and related  intellectual  property only in the field of urology. Mr.
Edwards has assigned to Rita Medical  Systems,  Inc.  ("RITA") his inventions in
the cancer field. Mr. Edwards has conceived of, and may continue to conceive of,
various  medical  device  product  concepts for other fields outside of urology,
including certain concepts


                                      -10-

<PAGE>


in the  gynecology  field that have been  licensed to an unrelated  party.  Such
party also has an option to  purchase  all future  technology  developed  by Mr.
Edwards in the gynecology  field.  Product concepts outside of urology developed
by Mr. Edwards will not be owned by or commercialized through VidaMed.

         Risks  Relating to RITA.  The Company has entered into a cross  license
agreement with RITA, formerly ZoMed International, Inc. Under the cross license,
RITA has the right to use VidaMed technology in the cancer field and VidaMed has
the right to use RITA  technology in the  treatment of  urological  diseases and
disorders.  The cross license  between VidaMed and RITA allows both companies to
develop  products  for  treatment  of  prostate  cancer and cancers of the lower
urinary  tract,  and VidaMed and RITA may therefore  become  competitors in this
field.

         Product Liability Risk; Limited Insurance Coverage. The business of the
Company entails the risk of product liability  claims.  Although the Company has
not experienced any product liability claims to date, any such claims could have
an adverse  impact on the  Company.  The  Company  maintains  product  liability
insurance and evaluates its insurance  requirements  on an ongoing basis.  There
can be no assurance that product liability claims will not exceed such insurance
coverage  limits  or that  such  insurance  will be  available  on  commercially
reasonable terms or at all.

         Effect  of  Certain  Charter,  Bylaw  and  Other  Provisions.   Certain
provisions of the Company's Certificate of Incorporation and Bylaws may have the
effect  of  making  it  more  difficult  for a third  party  to  acquire,  or of
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  allow the  Company  to issue  Preferred  Stock  without  any vote or
further action by the  stockholders,  eliminate the right of stockholders to act
by written  consent  without a meeting and  eliminate  cumulative  voting in the
election  of  directors.  These  provisions  may  make  it  more  difficult  for
stockholders  to take  certain  corporate  actions  and could have the effect of
delaying or preventing a change in control of the Company.

         No Public Market for the Warrants;  Arbitrary Determination of Purchase
Price; Price Volatility. Prior to the offering of the Securities, there has been
no public market for the Warrants,  and there can be no assurance that an active
trading market will develop in any of the Warrants  after any offering  thereof.
The  Company  does not intend to apply for the  listing of the  Warrants  on any
exchange.  The  exercise  price  and  terms of the  Warrants  may be  determined
arbitrarily  by  negotiations  between the Company  and any  purchaser  thereof.
Factors  considered  in such  negotiations,  in  addition to  prevailing  market
conditions,  may include the history and prospects for the industry in which the
Company competes,  an assessment of the Company's  management,  the prospects of
the Company,  its capital  structure  and certain  other  factors as were deemed
relevant.  Therefore,  the  exercise  price  and terms of the  Warrants  may not
necessarily  bear  any  relationship  to  established   valuation  criteria  and
therefore  may not be  indicative of prices that may prevail at any time or from
time to time in a public market for the Warrants.

         Legal  Restrictions  on Sales of Shares  Underlying  the Warrants.  The
Warrants  will  not be  exercisable  unless,  at the time of the  exercise,  the
Company has a current  prospectus  covering the shares of Common Stock  issuable
upon exercise of the Warrants,  and such shares have been registered,  qualified
or deemed to be exempt  under the  securities  laws of the state of residence of
the  exercising  holder of the Warrants.  Although the Company has undertaken to
use its best  efforts  to have all the  shares of  Common  Stock  issuable  upon
exercise of the Warrants  registered or qualified on or before the exercise date
and to maintain a current  prospectus  relating  thereto until the expiration of
the  Warrants,  there  can be no  assurance  that it will be able to do so.  The
Warrants may be deprived of value if a current prospectus covering the shares of
Common Stock issuable upon the exercise of the Warrants is not kept effective.

                                 USE OF PROCEEDS

         Unless otherwise specified in the applicable  Prospectus Supplement for
any  offering of  Securities,  the Company  intends to use the net  proceeds for
general corporate purposes.

         Pending use of the proceeds in the Company's  business,  the funds will
be invested in short-term investment grade interest bearing instruments.

                            DESCRIPTION OF SECURITIES

         The  authorized  capital  stock of the Company  consists of  30,000,000
shares of Common  Stock,  $.001 par value per  share,  and  5,000,000  shares of
Preferred  Stock,  $.001 par value per share.  As of January 9, 1997, 10,928,630
shares of Common Stock were  outstanding,  held of record by  approximately  263
stockholders.  No shares of the Preferred Stock were  outstanding as of December
31, 1996,  although  30,000  shares of the Preferred  Stock had been  designated
Series A  Participating  Preferred  stock,  $.001 par value.  In addition,  each
outstanding share of Common Stock represented the Preferred Share Purchase Right
related thereto.

Preferred Shares Purchase Rights

         The  Company's  Board of Directors has declared a dividend of one right
(a "Right") to  purchase  one  one-thousandth  share of the  Company's  Series A
Participating  Preferred Stock ("Series A Preferred") for each outstanding share
of Common Stock ("Common  Shares") of the Company.  The dividend will be payable
on January  31, 1997 (the  "Record  Date") to  stockholders  of record as of the
close of business on that date. Each Right will entitle the registered holder to
purchase from the Company one one-thousandth of a share of Series A Preferred at
an exercise price of $50.00 (the "Purchase Price"), subject to adjustment.

         The following summary of the principal terms of the Rights is a general
description  only and is subject to the  detailed  terms and  conditions  of the
Rights  Agreement  to be entered  into by the  Company and  American  Securities
Transfer, Inc., as Rights Agent (the "Rights Agent").

         Rights Evidenced by Common Share  Certificates.  The Rights will not be
exercisable until the Distribution Date (defined below).  Until the Distribution
Date,  certificates for the Rights ("Rights  Certificates")  will not be sent to
stockholders;  instead,  the Rights will attach to and trade only  together with
the Common Shares.  Accordingly,  Common Share  certificates  outstanding on the
Record  Date  will  evidence  the  Rights  related  thereto,  and  Common  Share
certificates issued after the Record Date will contain a notation  incorporating
the Rights Agreement by reference.  Until the Distribution  Date (or the earlier
redemption  or  expiration  of the  Rights),  the  surrender  or transfer of any
certificates  for Common Shares  outstanding as of the Record Date, even without
the notation or a copy of the Summary of Rights  being  attached  thereto,  will
also  constitute  the transfer of the Rights  associated  with the Common Shares
represented by such certificate.

         Distribution  Date.  The Rights will separate  from the Common  Shares,
Rights  Certificates will be issued and the Rights will become  exercisable upon
the  earlier  of:  (i) 10 days (or such  later  date as may be  determined  by a
majority of the Board of  Directors,  excluding  directors  affiliated  with the
Acquiring  Person,  as defined below (the "Continuing  Directors"))  following a
public  announcement that a person or group of affiliated or associated  persons
(an  "Acquiring  Person")  has  acquired,  or  obtained  the  right to  acquire,
beneficial  ownership of 20% or more of the outstanding  Common Shares; and (ii)
10 business  days (or such later date as may be  determined by a majority of the
Continuing  Directors)  following the  commencement  of, or  announcement  of an
intention to make, a tender offer or


                                      -12-

<PAGE>


exchange  offer  the  consummation  of  which  would  result  in the  beneficial
ownership by a person or group of 20% or more of the outstanding  Common Shares.
The earlier of such dates is referred to as the "Distribution Date."

         Issuance  of Rights  Certificates;  Expiration  of  Rights.  As soon as
practicable  following the Distribution Date,  separate Rights Certificates will
be mailed to holders of record of the Common  Shares as of the close of business
on the  Distribution  Date and such  separate  Rights  Certificates  alone  will
evidence  the Rights from and after the  Distribution  Date.  All Common  Shares
issued prior to the Distribution Date will be issued with Rights.  Common Shares
issued after the Distribution  Date may be issued with Rights if such shares are
issued (i) upon the  conversion  of  outstanding  convertible  debentures or any
other  convertible  securities  issued after adoption of the Rights Agreement or
(ii) pursuant to the exercise of stock options or under  employee  benefit plans
or  arrangements  unless such  issuance  would result in (or create a risk that)
such options,  plans or arrangements  would not qualify for otherwise  available
special tax treatment. Except as otherwise determined by the Board of Directors,
no other Common  Shares issued after the  Distribution  Date will be issued with
Rights.  The Rights  will expire on the  earliest  of (i)  November 7, 2006 (the
"Final Expiration Date"), (ii) redemption or exchange of the Rights as described
below, or (iii) consummation of an acquisition of the Company satisfying certain
conditions  by a person who  acquired  shares  pursuant to a Permitted  Offer as
described below.

         Initial Exercise of the Rights.  Following the  Distribution  Date, and
until one of the further events described  below,  holders of the Rights will be
entitled  to receive,  upon  exercise  and the payment of $50.00 per Right,  one
one-thousandth  share of the Series A  Preferred.  In the event that the Company
does not have  sufficient  Series A  Preferred  available  for all  Rights to be
exercised,  or the Board  decides that such action is necessary and not contrary
to the interests of Rights  holders,  the Company may instead  substitute  cash,
assets or other securities for the Series A Preferred for which the Rights would
have been exercisable under this provision or as described below.

         Right to Buy  Company  Common  Shares.  Unless the  Rights are  earlier
redeemed,  in the event that an Acquiring Person becomes the beneficial owner of
20% or more of the Company's Common Shares then outstanding (other than pursuant
to a Permitted  Offer),  then each  holder of a Right which has not  theretofore
been exercised (other than Rights  beneficially  owned by the Acquiring  Person,
which will thereafter be void) will  thereafter have the right to receive,  upon
exercise,  Common Shares  having a value equal to two times the Purchase  Price.
Rights are not  exercisable  following  the  occurrence of an event as described
above until such time as the Rights are no longer  redeemable  by the Company as
set forth below.

         Right to Buy  Acquiring  Company  Stock.  Unless the Rights are earlier
redeemed,  in the event  that,  after the Shares  Acquisition  Date (as  defined
below),  (i) the Company is acquired in a merger or other  business  combination
transaction,  or (ii)  the  Company  consummates  a  merger  or  other  business
combination  transaction  in which the Company is the  continuing  or  surviving
corporation,  or (iii) 50% or more of the Company's  assets or earning power are
sold,  each holder of a Right which has not  theretofore  been exercised  (other
than Rights beneficially owned by the Acquiring Person, which will thereafter be
void) will thereafter have the right to receive, upon exercise, shares of common
stock of (i) the corporation  acquiring the Company or (ii) the Company or (iii)
the  purchaser  of 50% or  more  of  the  Company's  assets  or  earning  power,
respectively,  such  shares in each case  having a value  equal to two times the
Purchase  Price (unless the  transaction  satisfies  certain  conditions  and is
consummated  with a person who acquired shares pursuant to a Permitted Offer, in
which case the Rights will expire).

         Permitted  Offer.  A  Permitted  Offer  means a  tender  offer  for all
outstanding  Common  Shares  that  has  been  determined  by a  majority  of the
Continuing  Directors  to be fair and  otherwise  in the best  interests  of the
Company and its stockholders. Where the Board of Directors has determined that a
tender  offer  constitutes  a  Permitted  Offer,  the  Rights  will  not  become
exercisable to purchase Common Shares or shares of the acquiring company (as the
case may be) at the discounted price described above.


                                      -13-

<PAGE>


         Exchange  Provision.  At any time after the acquisition by an Acquiring
Person of 20% or more of the  Company's  outstanding  Common Shares and prior to
the  acquisition  by such  Acquiring  Person  of 50% or  more  of the  Company's
outstanding  Common  Shares,  the Board of Directors of the Company may exchange
the Rights  (other than Rights owned by the  Acquiring  Person),  in whole or in
part, at an exchange ratio of one Common Share per Right.

         Redemption.  At any time on or prior to the  close of  business  on the
earlier of (i) the 10th day following the acquisition by an Acquiring  Person of
20% or more of the Company's  outstanding Common Shares (the "Shares Acquisition
Date") or such later date as may be determined  by a majority of the  Continuing
Directors and publicly  announced by the Company,  or (ii) the Final  Expiration
Date of the Rights, the Company may redeem the Rights in whole, but not in part,
at a price of $.01 per Right.

         Adjustments to Prevent Dilution. The Purchase Price payable, the number
of  Rights,  and the  number of  Series A  Preferred  or Common  Shares or other
securities  or  property  issuable  upon  exercise  of the Rights are subject to
adjustment  from time to time in connection  with the dilutive  issuances by the
Company  as set forth in the  Rights  Agreement.  With  certain  exceptions,  no
adjustment in the Purchase Price will be required until  cumulative  adjustments
require an adjustment of at least 1% in such Purchase Price.

         Cash Paid Instead of Issuing  Fractional  Shares. No fractional portion
less than integral multiples of one Common Share will be issued upon exercise of
a Right and in lieu  thereof,  an  adjustment  in cash will be made based on the
market price of the Common  Shares on the last trading date prior to the date of
exercise.

         No Stockholders' Rights Prior to Exercise.  Until a Right is exercised,
the holder thereof, as such, will have no rights as a stockholder of the Company
(other than any rights resulting from such holder's ownership of Common Shares),
including, without limitation, the right to vote or to receive dividends.

         Amendment of Rights  Agreement.  The provisions of the Rights Agreement
may be  supplemented or amended by the Board of Directors in any manner prior to
the close of business on the date of the  acquisition by an Acquiring  Person of
20% or more of the Company's  outstanding  Common Shares without the approval of
Rights  holders.  After the  Distribution  Date,  the  provisions  of the Rights
Agreement may be amended by the Board in order to cure any ambiguity,  defect or
inconsistency,  to make changes which do not  adversely  affect the interests of
holders of Rights  (excluding  the  interests of any  Acquiring  Person),  or to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to adjust the time period governing redemption shall
be made at such time as the Rights are not redeemable.

         Rights and  Preferences  of the Series A Preferred.  Series A Preferred
purchasable  upon exercise of the Rights will not be  redeemable.  Each share of
Series A Preferred will be entitled to an aggregate  dividend of 1,000 times the
dividend declared per Common Share. In the event of liquidation,  the holders of
the Series A Preferred  will be entitled to a minimum  preferential  liquidation
payment equal to $50,000 per share.  Each share of Series A Preferred  will have
1,000 votes, voting together with the Common Shares. In the event of any merger,
consolidation  or other  transaction  in which the Common  Shares are changed or
exchanged,  each share of Series A Preferred  will be entitled to receive  1,000
times the amount  received  per Common  Share.  These  rights are  protected  by
customary anti-dilution provisions.

         Because of the nature of the dividend, liquidation and voting rights of
the shares of Series A Preferred,  the value of the one one-thousandth  interest
in a share of Series A Preferred  purchasable upon exercise of each Right should
approximate the value of one Common Share.

         Certain  Anti-takeover  Effects.  The Rights  approved by the Board are
designed to protect and maximize the value of the outstanding  equity  interests
in the  Company in the event of an  unsolicited  attempt by an  acquiror to take
over the Company in a manner or on terms not approved by the Board of Directors.
Takeover attempts  frequently  include coercive tactics to deprive the Company's
Board of Directors and its stockholders of any real opportunity to determine the
destiny of the Company or to evaluate  and  protect the  long-term  value of the
Company.  The Rights are not intended to prevent a takeover of the Company.  The
Rights may be redeemed by the Company at $.01 per Right within ten days (or such
later date as may be determined by a majority of the Continuing Directors) after
the  accumulation of 20% or more of the Company's shares by a single acquiror or
group. Accordingly,  the Rights should not interfere with any merger or business
combination approved by the Board of Directors.

         Issuance  of the  Rights  does  not in any  way  weaken  the  financial
strength of the Company or interfere  with its business  plans.  The issuance of
the Rights themselves has no dilutive effect,  will not affect reported earnings
per share, should not be taxable to the Company or to its stockholders, and will
not  change the way in which the  Company's  shares are  presently  traded.  The
Company's  Board of  Directors  believes  that the Rights  represent a sound and
reasonable means of addressing the complex issues of corporate policy created by
the current takeover environment.

         However,  the Rights may have the effect of rendering more difficult or
discouraging  an acquisition  of the Company deemed  undesirable by the Board of
Directors.  The Rights may cause substantial  dilution to a person or group that
attempts  to acquire  the  Company on terms or in a manner not  approved  by the
Company's Board of Directors,  except pursuant to an offer  conditioned upon the
negation, purchase or redemption of the Rights.

Common Stock Warrants

         The following  summary  description  of the Warrants sets forth certain
general terms and provisions of the Warrants to which any Prospectus  Supplement
may relate, but such summary does not purport to be complete and is qualified in
all  respects  by  reference  to the actual  text of the Common  Stock  Purchase
Warrant.

         Exercise  Price and Terms.  Each Warrant  will  entitle the  registered
holder  thereof to purchase,  for a fixed time period  commencing on the date of
issuance,  a fixed number of shares of Common Stock at a fixed price per  share,
subject to adjustment in accordance with the  anti-dilution and other provisions
referred  to below.  The holder of any  Warrant  will be able to  exercise  such
Warrant by  surrendering  the certificate  representing  the Warrant to American
Securities  Transfer,  Inc., (the "Warrant  Agent"),  with the subscription form
thereon properly  completed and executed,  together with payment of the exercise
price.  The  Warrants  may be  exercised  at any time in whole or in part at the
applicable exercise price until expiration of the Warrants. No fractional shares
will be issued upon the exercise of the Warrants.

         The  exercise  price of the Warrants  may bear no  relationship  to any
objective criterion of value and should in no event be regarded as an indication
of any future market price of the Common Stock.

         Adjustments.  The  exercise  price  and the  number of shares of Common
Stock  purchasable  upon  the  exercise  of the  Warrants  will  be  subject  to
adjustment  upon the  occurrence  of certain  events,  including  stock  splits,
reverse stock splits or combinations of the Common Stock, or sale by the Company
of shares of its Common Stock or other securities  convertible into Common Stock
at a price below the fair market  value of the Common  Stock.  Additionally,  an
adjustment may be made in the case of a  reclassification  or exchange of Common
Stock,  consolidation or merger of the Company with or into another  corporation
(other  than a  consolidation  or merger in which the  Company is the  surviving
corporation) or sale of all or substantially all of the assets of the Company in


                                      -15-

<PAGE>


order to enable warrantholders to acquire the kind and number of shares of stock
or other  securities  or  property  receivable  in such event by a holder of the
number of shares of Common Stock that might  otherwise  have been purchased upon
the exercise of the Warrant.

         Transfer,  Exchange and  Exercise.  The Warrants  will be in registered
form and may be  presented  to the  Warrant  Agent  for  transfer,  exchange  or
exercise  at any time on or prior to their  expiration  date,  at which time the
Warrants will become  wholly void and of no value.  If a market for the Warrants
develops, the holder may sell the Warrants instead of exercising them. There can
be no  assurance,  however,  that a market  for the  Warrants  will  develop  or
continue  and the  Company  does not  intend  to apply  for the  listing  of the
Warrants on any exchange.

         Warrantholder  Not a  Stockholder.  The  Warrants  will not confer upon
holders any voting, dividend or other rights as stockholders of the Company.

         Modification of Warrant.  Modification  of the Warrants,  including the
modification  of the  number  of shares of  Common  Stock  purchasable  upon the
exercise of any Warrant, the exercise price and the expiration date with respect
to any  Warrant,  will  require  the consent of the holders of a majority of the
Warrants.

         The  Warrants  will  not be  exercisable  unless,  at the  time  of the
exercise,  the Company has a current  prospectus  covering  the shares of Common
Stock  issuable  upon  exercise  of the  Warrants,  and such  shares  have  been
registered,  qualified or deemed to be exempt under the  securities  laws of the
state of  residence  of the  exercising  holder of the  Warrants.  Although  the
Company has  undertaken to use its best efforts to have all the shares of Common
Stock  issuable  upon  exercise of the  Warrants  registered  or qualified on or
before the exercise date and to maintain a current  prospectus  relating thereto
until the expiration of the Warrants,  there can be no assurance that it will be
able to do so.

                              PLAN OF DISTRIBUTION

         The Company may sell Securities to or through one or more underwriters,
and also may sell Securities directly to other purchasers or through agents.

         The distribution of the Securities may be effected from time to time in
one or more  transactions at a fixed price or prices,  which may be changed,  at
market  prices  prevailing  at the  time of  sale,  at  prices  related  to such
prevailing market prices or at negotiated prices.

         In connection  with the sale of  Securities,  underwriters  may receive
compensation  from the Company or from  purchasers of Securities,  for whom they
may act as  agents,  in the  form of  discounts,  concessions,  or  commissions.
Underwriters  may sell  securities  to or through  dealers and such  dealers may
receive compensation in the form of


                                      -16-

<PAGE>


discounts,  concessions, or commissions from the underwriters and/or commissions
from the  purchasers  for whom they may act as agents.  Any such  underwriter or
agent will be identified,  and any such  compensation  received from the Company
will be described, in the Prospectus Supplement.

         Any Common Shares sold pursuant to a Prospectus Supplement are expected
to be listed on the Nasdaq National Market.  Unless  otherwise  specified in the
related Prospectus Supplement,  each series of Warrants will be a new issue with
no  established  trading  market.  The  Company  may elect to list any series of
Warrants on an exchange,  but is not obligated to do so. It is possible that one
or more underwriters may make a market in a series of Warrants,  but will not be
obligated  to do so and may  discontinue  any market  making at any time without
notice.  Therefore, no assurance can be given as to the liquidity of the trading
market of any Securities.

         Under agreements the Company may enter into, underwriters,  dealers and
agents who  participate  in the  distribution  of Securities  may be entitled to
indemnification   by  the  Company   against  certain   liabilities,   including
liabilities under the Securities Act.

         Underwriters,  dealers and agents may engage in  transactions  with, or
perform  services for, or be customers of, the Company in the ordinary course of
business.
