                                     SUMMARY

         VidaMed designs, develops, and markets urological systems that are used
for urinary tract disorders. Our technologically and clinically advanced systems
are cost  effective.  We  primarily  treat  the  enlarged  prostrate  or  benign
prostatic hyperplasia, a noncancerous condition of the prostrate gland effecting
urination.  VidaMed's primary product,  the patented VidaMed TUNA Systems,  is a
reasonably priced alternative  therapy that minimizes  surgical  invasion,  side
effects and  complications  for this condition.  On October 8, 1996, we received
510(k) clearance from the United States Food and Drug Administration to sell the
TUNA System commercially in the United States. In the United States, we sell our
products primarily through direct sales personnel. Internationally, we primarily
sell to distributors who resell to physicians and hospitals.

         VidaMed  has  designed  and  developed  the  TUNA  System  and the TUNA
Procedure for restoring and improving  urinary flow in patients  suffering  from
benign  prostatic  hyperplasia.  Compared to other therapies for treating benign
prostatic hyperplasia,  such as drug therapy and current surgical therapies, the
TUNA Procedure:

o        Results in fewer complications and adverse effects;
o        Requires shorter recovery time; and
o        Costs less.

         Because the Tuna Procedure can be performed on an outpatient  basis, it
will result in relatively fewer complications and reduced expense.

         The TUNA System mainly consists of:

o        A single-use  needle  ablation hand piece that delivers radio frequency
         energy to the prostate;
o        A low power radio frequency energy generator; and
o        An optical device that allows direct viewing during the procedure.

TUNA Hand Piece.

         The single-use  TUNA hand piece measures  18-1/2 French  (approximately
five  millimeters) in diameter and contains  needles along its sides that extend
at an angle of approximately 90 degrees.  A patented,  retractable shield covers
each needle. These shields protect the urethra and are adjusted by the urologist
to selectively control the area of prostate tissue ablated or pierced during the
procedure.  The needle and shields can  independently  advance and retract using
controls  on the hand  piece.  Thermocouples  on the  shield tip and at the hand
piece tip record temperatures at the lesion site and in the prostatic urethra.

         The hand piece allows for irrigation,  aspiration and bladder  drainage
during the  procedure  without  removing the handpiece  from the bladder.  These
features  improve the view of the area of treatment  and reduce  post-procedural
urethral irritation. In addition, these capabilities allow the physician to more
closely control urethral tissue temperature during the procedure.

TUNA Radio Frequency Generator.

         The TUNA radio frequency energy generator is designed  specifically for
use with the TUNA hand piece. The generator has digital displays  indicating the
temperature  at each  thermocouple,  the power being  delivered  to each needle,
ablation time and electrical impedance. The physician uses these measurements to
control  tissue  ablation.  The generator uses both automated and manual control
modes.

                                       3

<PAGE>

The  generator  has an  automatic  shut-off  activated by both  temperature  and
impedance measurements to ensure controlled ablation or piercing of the tissue.

TUNA Optics.

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

         The TUNA Procedure desiccates prostatic tissue and nerve endings in the
prostate to improve  symptoms such as urgency and  frequency  with urinary flow.
The  procedure  takes 30 to 45  minutes  using  local  anesthesia  which  may be
supplemented by intravenous  sedation.  The TUNA hand piece is inserted into the
patient's  urethra.  The two shielded needle electrodes then advance into one of
the two  lateral  lobes  of the  prostate.  Controlled  radio  frequency  energy
delivered by the needle  electrodes heats targeted portions of the prostate lobe
to temperatures of 90 to 100 degrees  centigrade,  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 hand piece 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 TUNA System.

         The design of the VidaMed  TUNA  System  offers  advantages  over other
therapies.  Because the TUNA System shields the urethra and delivers  controlled
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
Procedure indicate that the TUNA Procedure results in fewer of the complications
associated  with  transurethral  resection  of prostate  surgery,  the  standard
treatment for benign  prostatic  hyperplasia,  including  impotence,  retrograde
ejaculation and incontinence.

         The  cost  of the  TUNA  Procedure  in  the  United  States,  including
physician  charges,  will be less than the  standard  treatment.  The TUNA radio
frequency  generator  costs less than the general  surgical  lasers  required to
perform laser  procedures and the ultrasound and microwave  devices required for
other  surgical  procedures.  The TUNA  Procedure  can be done on an  outpatient
basis, further reducing costs.

                                  RISK FACTORS

         An  investment  in the  securities  being  offered  by this  prospectus
involves a high degree of risk. You should consider the following  factors,  and
those discussed elsewhere in this prospectus, before purchasing our securities.

VIDAMED HAS A LIMITED HISTORY OF OPERATIONS.

         Since  inception  in July  1992,  we have  been  primarily  engaged  in
research  and  development  of the  VidaMed  TUNA  System.  We have  experienced
significant  operating  losses since inception and, as of December 31, 1998, had
an accumulated deficit of $88.2 million.

VIDAMED ANTICIPATES LOSSES RELATED TO PRODUCT DEVELOPMENT.

         The TUNA System and other new products,  if any,  will require  product
development,  clinical,  regulatory,  marketing and other expenditures.  VidaMed
expects operating losses to continue as it continues to:

    o    Expand marketing and sales activities;
    o    Fund clinical trails to support regulatory and reimbursement approvals;
         and
    o    Engage in research and development.

         Both domestically, and abroad, profitability remains uncertain. Results
of  operations  may  fluctuate  significantly  from quarter to quarter.  Factors
affecting operations include:

    o    Regulatory actions;
    o    Reimbursement matters;
    o    Progress of clinical trials;
    o    Market acceptance of the TUNA System;
    o    Pricing promotions;
    o    Volume discounts to distributors;
    o    Alternative therapies for benign prostatic hyperplasia; and
    o    Competition.

VIDAMED'S PRODUCTS MUST ACHIEVE GREATER ACCEPTANCE.

         VidaMed's  TUNA  Procedure  is  a  new  therapy.  Even  when  necessary
international and United States reimbursement  approvals are obtained,  the TUNA
System must gain market  acceptance  among  physicians,  patients and healthcare
payors.  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 treatment.  Physicians  may not recommend the TUNA Procedure
until  the  duration  of the  relief  provided  by the  procedure  can be better
established and acceptable reimbursement from health care payors is available.

         Broad use of the TUNA  System  will  require  the  training of numerous
physicians.  The time required to complete such training could result in a delay
or dampening of market acceptance.

         Health  care  payor  acceptance  of the  TUNA  Procedure  will  require
evidence  that it costs  less  than  other  therapies.  The TUNA  Procedure  can
demonstrate cost effectiveness over time if it provides  long-lasting  relief to
patients.  A thorough  analysis can assess the durability of the relief provided
by TUNA  therapy.  This  requires  follow-up  data on patients  over a period of
years.

                                       1

<PAGE>

         Patients' acceptance of the procedure will depend on factors including:

    o    Physician recommendations;
    o    Degree of invasiveness;
    o    Rate and severity of complications; and
    o    Relative effectiveness of other therapies.

VIDAMED DEPENDS ON THIRD PARTY REIMBURSEMENT.

         Our success among other  things,  requires  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. In the United States, third party reimbursement for the TUNA
Procedure depend on decisions by the local Medicare Medical  Directors who adopt
Medicare  reimbursement  guidelines 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.  We have  received  approvals  by the Ministry of Health and Welfare in
Japan and by the British Provident  Association Ltd., the largest private health
care insurer in the United Kingdom.

         Reimbursement  requires  physician advocacy of the VidaMed TUNA System.
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.  In the United States,  TUNA Procedures are currently
being reimbursed by certain private payors.  However,  Medicare reimbursement is
particularly  critical for widespread market acceptance of the TUNA Procedure in
the United States because of the age of patients using it.

         CPT Code  #53852,  covering  the  physician  fee  component of the TUNA
Procedure,  was included in the 1998 edition of CPT codes which became effective
January 1,  1998.  If adopted by local  Medicare  Medical  Directors,  this code
should enhance the reimbursement  process for physicians  performing the VidaMed
TUNA Procedure in an outpatient hospital environment.  The CPT code is presently
active in over 35 states covering reimbursement of the VidaMed TUNA Procedure in
the  hospital.  While we  continue  to work  with the  remaining  state  Medical
Directors, there is no assurance when or if the remaining states will reimburse.

         Office  reimbursement  is expected to phase in after the federal office
of Health Care Financing  Administration resolves its Year 2000 issues, which is
projected  to  be  on or  after  June  30,  2000.  We  cannot  assure  you  that
office-based  reimbursement  for our  products  will be  available in the United
States  or  in  international  markets  under  either  governmental  or  private
reimbursement  systems at adequate  reimbursement levels. Nor can we assure that
physicians will support reimbursement for the VidaMed TUNA Procedure. Changes in
reimbursement  policies of governmental or private health care payors could also
have a material adverse effect on VidaMed's  business,  financial  condition and
results of operations.

VIDAMED MAY REQUIRE ADDITIONAL FINANCING.

         VidaMed plans to:

    o    Continue clinical trails for regulatory and reimbursement approvals;
    o    Expand sales and marketing activities; and
    o    Research and develop products.

                                      -2-

<PAGE>

         Expenditures may be greater than anticipated if unforeseen difficulties
arise.  Our financial plan indicates that funds  available  through our existing
bank credit facilities, cash reserves and the future sales will be sufficient to
meet  our  operating  and  capital  requirements  during  the  next  12  months.
Nevertheless,  we cannot  assure you that  VidaMed  will not require  additional
financing within this time frame.

         The Company's  future  liquidity and capital  requirements  will depend
upon numerous factors, including;

    o    Progress of clinical  trials;
    o    Actions relating to regulatory and reimbursement matters; and
    o    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  financing may dilute the equity of
our current  stockholders.  Future debt financings may require VidaMed to pledge
assets and to comply with financial and operational covenants.

VIDAMED'S STOCK PRICE WILL FLUCTUATE.

         The  stock  market  has  experienced   significant   price  and  volume
fluctuations  that are  unrelated to the  operating  performance  of  particular
companies  necessarily cause such fluctuations.  Conversely,  these broad market
fluctuations  may  adversely  affect the market price of our common  stock.  The
market  price of our  common  stock is likely to be highly  volatile  because of
factors  such  as:

o  Fluctuations  in  the  Company's   operating  results;
o  Announcements  of  technological  innovations  or new products;
o  Food and Drug Administration and international  regulatory  actions,
o  Actions with respect to reimbursement  matters;
o  Developments  with respect to patents or proprietary rights;
o  Public concern as to the safety of our products;
o  Changes in health care policy in the United States and internationally;
o  Changes in stock market analyst recommendations;
o  Other medical device companies or the medical device industry generally;
o  General market conditions.

MOST OF VIDAMED'S COMPETITORS HAVE GREATER RESOURCES.

         Intense  market  competition  exists for treatment of benign  prostatic
hyperplasia  and  such  competition  is  expected  to  increase.  Our  principal
competition  will most  likely  come from  invasive  surgical  procedures,  drug
therapy,  other minimally invasive  therapies and watchful waiting.  Most of our
competitors have financial,  technical, research, marketing, sales, distribution
and other resources that are  significantly  greater than ours. We cannot assure
you that our  competitors  will not succeed in developing or marketing  superior
technologies and products.

         Any  product we develop  that gains  regulatory  approval  will have to
compete  for market  acceptance  and  market  share.  Important  factors in such
competition include the relative speed with which we can:

o  Develop products;
o  Complete clinical testing
o  Obtain regulatory approval processes;
o  Gain reimbursement acceptance;

                                      -3-

<PAGE>

o  Supply commercial quantities of the product to the market; and
o  Demonstrate safe, effective and lasting treatment.

VIDAMED'S PRODUCTS MUST COMPLY WITH U.S. GOVERNMENT REGULATIONS.

         The Food and  Drug  Administration  regulates  the TUNA  System  in the
United  States as a medical  device under the Federal Food,  Drug,  and Cosmetic
Act.  Pursuant  to  the  act,  the  administration  regulates  the  manufacture,
distribution  and production of all medical  devices in the United  States.  Any
failure to comply with the requirements of the act can result in:

o  Fines;
o  Injunctions;
o  Civil penalties;
o  Recall or seizure of products;
o  Total or partial suspension of production;
o  Failure of the government to grant approval for devices; and
o  Criminal prosecution.

         Medical devices are classified into Class I, II or III, on the basis of
the controls  necessary  to  reasonably  ensure their safety and  effectiveness.
Controls  for Class I  devices  include  general  controls,  such as,  labeling,
premarket  notification  and  adherence  to  standards  set by the Food and Drug
Administration for good manufacturing  practices.  Controls for Class II devices
include the use of special controls,  such as performance standards,  postmarket
surveillance,  patient registries, and federal guidelines.  Generally, Class III
devices,  such as life-sustaining,  life-supporting and implantable  devices, or
new  devices  which  have not been  found  substantially  equivalent  to legally
marketed devices,  are those which must receive  premarket  approval by the Food
and Drug Administration.

         Before a new device can be introduced into the market, the manufacturer
must  generally  obtain  clearance  through  either a 510(k)  notification  or a
premarket  approval.  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  administration  has not called for premarket  approval.  The Food and
Drug Administration 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
administration  may  determine  that the  proposed  device is not  substantially
equivalent,  or that  additional  data is needed before a  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 adversely  effect our business,  financial  condition and
results of operations.  There can be no assurance  that:


o  We 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; or
o  We will not be required to submit a premarket  approval  application  for any
   device which we may develop in the future.

         For any of  VidaMed's  products  that are  cleared  through  the 510(k)
process,  including our TUNA System,  modifications  or enhancements  that could
affect safety or efficacy will require new 510(k) submissions.

                                      -4-

<PAGE>

VIDAMED PRODUCTS MUST COMPLY WITH FOREIGN GOVERNMENT REGULATIONS.

         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 in the United  States.  The  requirements  may also
differ.  VidaMed has received regulatory approvals where required for commercial
sale of the TUNA System in all major international markets.

         In June 1994,  we received a report of  compliance  for the TUNA System
from the British Standards  Institute.  In August 1994 we received a certificate
of compliance from TUV, a European  quality  assurance  auditor,  certifying the
TUNA  System's  safety and its  adherence to published  electronic or mechanical
specifications.

         These  certifications  allow  the  Company  to affix the CE mark to the
VidaMed  TUNA System,  permitting  us to  commercially  market and sell the TUNA
System in all  countries of the  European  Economic  Area.  In order to maintain
these  approvals,  we are subject to periodic  inspections.  Additional  product
approvals from foreign regulatory  authorities may be required for international
sale of our general  electrosurgical  device for which a 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 our  business,  financial  condition and results of
operations.

         VidaMed's  distributor in Japan, Century Medical,  Inc., is responsible
for management of clinical  trials and obtaining  regulatory  and  reimbursement
approval for the TUNA System.  Such  regulatory  approval was received  from the
Japanese Ministry of Health and Welfare in July 1997. However, failure to obtain
approval of current or future  products or to obtain market  acceptance  for the
TUNA Procedure in Japan could preclude the commercial  viability of our products
in Japan and could  adversely  effect on our business,  financial  condition and
results of operations.

MANUFACTURING DIFFICULTIES POSE RISKS TO VIDAMED.

         VidaMed  relies on  outside  companies  to  manufacture  our  products.
Manufacturers  often  encounter  difficulties  in scaling up  production  of new
products. Such difficulties involve:

o  Production yields;

o  Quality control and assurance;

o  Component supply; and

o  Lack of qualified personnel.

         These  difficulties,  if  encountered by the  manufacturers  of VidaMed
products,  could adversely effect our business,  financial condition and results
of operations.  We cannot assure you that current  manufacturers will adequately
meet our manufacturing needs on an on-going basis.

         Any products  manufactured  or distributed by VidaMed  pursuant to Food
and Drug  Administration  clearances  or  approvals  are  subject to  continuing
regulation,  including recordkeeping and reporting requirements regarding use of
the  device.  Manufacturing  facilities  where we  outsource  products  are also
subject  to  periodic  inspection  by  federal,  state  and  foreign  regulatory
agencies.  Failure of our  manufacturers to comply with regulatory  requirements
could adversely effect our business.

                                      -5-

VIDAMED'S CANNOT COMPLETELY PROTECT ITS INTELLECTUAL PROPERTY.

         We have been issued 42 United  States  patents  and 40 foreign  patents
covering a method of prostate  ablation  using the  VidaMed  TUNA System and the
design of the TUNA System. We currently have 16 patent  applications  pending in
the United States and 49 corresponding  patent  applications  pending in various
foreign countries.  In addition,  we hold licenses to certain technology used in
the TUNA System. We cannot assure that our issued United States patents,  or any
patents which may be issued to us, will offer any degree of protection.

         We cannot  assure that any of our patents or patent  applications  will
not be challenged,  invalidated or circumvented in the future. In addition, many
of  our  competitors  have  substantial  resources  and  have  made  substantial
investments in competing  technologies.  Such  competitors may seek to apply for
and obtain  patents that will  prevent,  limit or interfere  with our ability to
make, use or sell our products  either in the United States or in  international
markets.

         Extensive litigation regarding patents and other intellectual  property
rights characterize the medical device industry. Companies in the medical device
industry  have  used  intellectual  property  litigation  to gain a  competitive
advantage.  VidaMed is aware of patents held by other participants in the benign
prostatic  hyperplasma  market.  We have been and may in the future be  notified
that we may be infringing patent or other  proprietary  rights.  Conversely,  in
1998,  we entered a  settlement  agreement  with  respect to a claim that we had
brought against another medical device company. Although patent and intellectual
property  disputes in the medical  device area have often been  settled  through
licensing or similar arrangements,  costs could be substantial and could include
ongoing  royalties.  We cannot assure that necessary licenses would be available
to us on satisfactory terms or at all.

         The defense and  prosecution of  intellectual  property  suits,  United
States and  Trademark  Office  interference  proceedings  and related  legal and
administrative proceedings consume money and time. Nevertheless,  litigation may
be necessary  to:

o  Enforce patents issued to;
o  Protect our trade secrets or know-how;
o  Determine the enforceability, scope and validity of the proprietary rights of
   others.

         Litigation  or  interference  proceedings  could  drain  our  financial
resources   and  divert  the  efforts  of  our  human   resources.   An  adverse
determination  in litigation  or  interference  proceedings  could subject us to
significant  liabilities  to third  parties or require us to seek  licenses from
third  parties.  An  adverse  determination  in  a  judicial  or  administrative
proceeding  or  failure  to obtain  necessary  licenses  could  prevent  us from
manufacturing  and  selling  our  products,  which  would  adversely  effect our
business, financial condition and results of operations.

         In  addition  to  patents,  we rely on trade  secrets  and  proprietary
know-how.  We seek to protect these, in part,  through  proprietary  information
agreements  with  employees,  consultants  and other  parties.  Our  proprietary
information  agreements with employees and consultants contain industry standard
provisions.  Such provisions require  individuals to assign to VidaMed,  without
additional  consideration,  any  inventions  that  they  conceive  or  reduce to
practice while employed or retained by us, subject to customary  exceptions.  We
cannot  assure  that   proprietary   information   agreements   with  employees,
consultants  and  others  will  not be  breached,  that we would  have  adequate
remedies for any breach,  or that our trade  secrets will not  otherwise  become
known to or independently developed by competitors.

         The proprietary information agreement between the Company and Stuart D.
Edwards,  one of our founders,  obligates  Mr.  Edwards to assign to VidaMed his
inventions and related  intellectual  property only in the field of urology. Mr.
Edwards has assigned to Rita Medical Systems,  Inc. 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.  Mr.
Edwards'  intellectual  property  includes  certain  product  concepts  for  the
treatment of snoring and sleep apnea that have been assigned and certain product
concepts in the gynecology  field that have been licensed to an unrelated  third
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,
and VidaMed will have no rights or ownership interests with respect thereto.

         We  have  entered  into a  cross  license  agreement  with  RitaMedical
Systems,  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.

VIDAMED IS AT RISK FOR PRODUCT LIABILITY CLAIMS.

         Although we have not experienced any product  liability claims to date,
any such claims could adversely  impact us. We may not be able to obtain product
liability insurance and evaluate our insurance requirements on an ongoing basis.
We cannot assure 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.

VIDAMED'S CORPORATE STRUCTURE INHIBITS STOCKHOLDERS' CONTROL.

         Certain  provisions  of our  Certificate  of  Incorporation  and Bylaws
inhibit  stockholders  control of VidaMed  by:

o  Allowing  the Company to issue  preferred  stock  without any vote or further
   action by the stockholders;
o  eliminating  the right of  stockholders  to act by written  consent without a
   meeting; and
o  eliminating cumulative voting in the election of directors.

         Because these provisions may make it more difficult for stockholders to
take  certain  corporate  actions,  they could have the  effect of  delaying  or
preventing a change in control of VidaMed. Such provisions could limit the price
that certain  investors  might be willing to pay for future shares of our common
stock.

NO PUBLIC MARKET EXITS FOR VIDAMED'S WARRANTS

         We do not  intend  to apply  for the  listing  of the  warrants  on any
exchange. Accordingly, no public market for the warrants will exist prior to the
offering of 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
exercise  price and  terms of the  warrants  may be  determined  arbitrarily  by
negotiations with any purchaser.  Factors  considered in such  negotiations,  in
addition  to  prevailing  market  conditions,  may  include:

o  The history and prospects of the industry;
o  An assessment of our management;
o  VidaMed's prospects;
o  Our capital structure; and;

                                      -7-

<PAGE>

o  Other relevant factors.

         Therefore,  the  exercise  price  and  terms  of the  warrants  may not
necessarily  bear  any  relationship  to  established  valuation  criteria.  The
exercise price, therefore, may not indicate prevailing prices in a public market
for the warrants.

         The  warrants  will  not be  exercisable  unless,  at the  time  of the
exercise:

o  VidaMed has a current prospectus covering the shares of common stock issuable
   upon exercise of the warrants; or
o  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.

         We will use our 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  until the expiration of the
warrants.  However, we cannot assure that we 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.

                                   PROSPECTUS

                                  VIDAMED, INC.

                        6,000,000 Shares of Common Stock
                   2,629,413 Warrants to Purchase Common Stock
                        2,000,000 Shares of Common Stock
                       Issuable Upon Exercise of Warrants

         This  Prospectus  relates to (i)  6,000,000  shares (the  "Shares")  of
common stock,  $.001 par value per share (the "Common  Stock"),  (ii)  2,000,000
Warrants to purchase Common Stock (the "Shelf Warrants"), (iii) 2,000,000 shares
of Common Stock issuable upon exercise of the Shelf Warrants (the "Shelf Warrant
Shares")  and (iv)  629,413  Warrants  to  purchase  Common  Stock (the  "Resale
Warrants") of VidaMed, Inc. (the "Company" or "VidaMed").  The Shares, the Shelf
Warrants and the Shelf Warrant Shares collectively are referred to herein as the
"Shelf Securities."

         The Resale  Warrants  may be offered  by  certain  stockholders  of the
Company  (the  "Selling  Warrant  Holders")  from  time  to  time  in  privately
negotiated transactions,  through the writing of options on the Resale Warrants,
or through a  combination  of such methods of sale,  at fixed prices that may be
changed,  at market prices prevailing at the time of sale, at prices relating to
such  prevailing  market prices or at  negotiated  prices.  The Selling  Warrant
Holders  may effect  such  transactions  by selling  the Resale  Warrants  to or
through broker-dealers,  and such broker-dealers may receive compensation in the
form of discounts,  concessions or commissions  from the Selling Warrant Holders
and/or the purchasers of the Resale  Warrants for whom such  broker-dealers  may
act  as  agents  or to  whom  they  may  sell  as  principals,  or  both  (which
compensation  as to a particular  broker-dealer  might be in excess of customary
commissions). See "Selling Warrant Holders" and "Plan of Distribution."

         None of the  proceeds  from  the  sale of the  Resale  Warrants  by the
Selling Warrant Holders will be received by the Company.  The Company has agreed
to bear all expenses  (other than selling  commissions  and fees and expenses of
counsel and other advisers to the Selling  Warrant  Holders) in connection  with
the  registration  and sale of the Resale  Warrants being offered by the Selling
Warrant Holders. The Company has agreed to indemnify the Selling Warrant Holders
against certain liabilities,  including  liabilities under the Securities Act of
1933, as amended (the "Securities Act").

         All  the  Resale  Warrants  were  "restricted   securities"  under  the
Securities Act prior to their registration hereunder. The Company sold 2,517,652
shares of Common Stock and 629,413  Warrants to the Selling  Warrant  Holders in
private  transactions in September  1997.  Such 629,413  Warrants are the Resale
Warrants registered hereunder.  This Prospectus has been prepared so that future
sales of Resale  Warrants by the Selling  Warrant Holders will not be restricted
under the  Securities  Act. In connection  with any sales,  the Selling  Warrant
Holders  and  any  brokers  participating  in such  sales  may be  deemed  to be
"underwriters"  within the meaning of the Securities  Act. See "Selling  Warrant
Holders."

         The  Company  may from  time to time  offer  the  Shelf  Securities  in
amounts,  at prices and on terms to be determined  at the time of offering.  The
Shelf  Securities may be offered  separately or together,  in separate series in
amounts,  at  prices  and on  terms  to be set  forth  in  supplements  to  this
Prospectus (each a "Prospectus Supplement").

         The  specific  terms of the Shelf  Securities  in respect of which this
Prospectus is being  delivered  will be set forth in the  applicable  Prospectus
Supplement and will include,  where  applicable:  (i) in the case of the

                                      -2-

<PAGE>

Shares,  any public  offering price and (ii) in the case of the Shelf  Warrants,
the terms of issuance and exercise and any public offering price.

         The applicable  Prospectus  Supplement  will also contain  information,
where applicable,  about certain United States federal income tax considerations
relating to, and any listing on a securities  exchange of, the Shelf  Securities
covered by such Prospectus Supplement.

         The Shelf  Securities  offered  by this  Prospectus  may be sold by the
Company from time to time through agents or  underwriters,  or to dealers acting
as  principals,  or directly to purchasers in  negotiated  transactions,  or any
combination  of these methods of sale.  Sales may be made at  prevailing  market
prices or at fixed  prices  determined  at the time of each  sale.  See "Plan of
Distribution"  regarding  Prospectus  Supplements  to be  appended  to  disclose
compensation by the Company to agents or underwriters  that may be designated to
participate in the offering of the Shelf  Securities.  The Company may indemnify
any participating  agent or underwriter against certain  liabilities,  including
liabilities  under the Securities  Act of 1933.  Expenses of the offering of the
Shelf  Securities,  estimated at $80,000  (excluding  compensation  to agents or
underwriters), will be paid by the Company.

         The Company's  Common Shares are traded on the Nasdaq  National  Market
System under the symbol "VIDA."

                                   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 on the
treatment of benign prostatic  hyperplasia ("BPH"). The Company's first product,
the  patented  VidaMed  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 used in the
TUNA  Procedure  as the therapy of choice for BPH over  watchful  waiting,  drug
therapy  and  current  surgical  therapies.  The TUNA  Procedure  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
the TUNA Procedure 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 hand piece 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 Hand  Piece.  The  single-use  TUNA hand piece  measures 22 French
(approximately  seven  millimeters) in diameter and contains  laterally deployed
needles  that extend at an angle of  approximately  90  degrees.  Each needle is
encased by a patented  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 hand piece  handle  allow for
independent advancement and retraction of the needle and shields.  Thermocouples
located at the shield tip and at the hand piece tip record  temperatures  at the
lesion site and in the prostatic urethra.  The hand piece allows for irrigation,
aspiration  and bladder  drainage  during the  procedure  without  removing  the
handpiece from the bladder.  These features improve visualization of the area of
treatment and reduce  post-procedural  urethral irritation.  In addition,  these
capabilities  allow  the  physician  to more  closely  control  urethral  tissue
temperature during the procedure.

         TUNA RF Generator.  The TUNA radio frequency ("RF") energy generator is
designed  specifically  for use with the TUNA hand piece.  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
hand piece  between the  verumontanum  and the bladder neck during the procedure
using direct  visualization.  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.

                                      -5-

<PAGE>

         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 hand
piece is  inserted  into the  patient's  urethra,  and the two  shielded  needle
electrodes  are then advanced into 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 hand piece 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 VidaMed 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 Procedure  indicate that the TUNA Procedure  results
in  fewer  of the  complications  associated  with  transurethral  resection  of
prostate  ("TURP")  surgery,  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, which is the standard surgical procedure to treat BPH. The TUNA RF
generator is typically  currently  sold at  approximately  $35,000 in the United
States, 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  the VidaMed  TUNA  Procedure  will also  provide
patients,  physicians and health care payors with a clinically and  economically
superior alternative to ongoing drug therapy, other minimally invasive surgeries
and watchful waiting. To date, the symptomatic relief experienced by patients in
the Company's  clinical trials  suggests that TUNA provides  greater relief than
drug  therapy or  watchful  waiting.  The  Company  believes  that if the relief
provided  by TUNA  proves  to be  sufficiently  durable,  TUNA  may  prove to be
economically  superior to the  noninvasive  approaches.  To date,  the Company's
available two to three-year  clinical follow-up data for TUNA Procedure patients
does not suggest the need for retreatment within this time frame. However, there
can be no assurance as to whether and how  frequently  TUNA  Procedure  patients
will require retreatment.

         In September 1997,  VidaMed announced a restructuring  program designed
to reduce  costs and improve  operating  efficiencies  by closing the  Company's
United Kingdom manufacturing  facility. The Company anticipates that following a
short  transition  period,  all future  manufacturing of the VidaMed TUNA System
hand pieces will occur in the United States.  In this regard,  the Company moved
into its new  headquarters  facility in Fremont,  California  in July 1997.  The
facility is approximately 35,000 square feet and provides the necessary capacity
to manufacture the VidaMed TUNA hand piece. The Company is currently  qualifying
the facility as an FDA, GMP and ISO9001 site.


                               RECENT DEVELOPMENTS

         On January 21, 1998, the Company reported its financial  results of the
fourth quarter and for the year ended  December 31, 1997. The Company's  revenue
for the fourth  quarter of 1997 was $2.0  million,  compared to $2.4 million for
the  fourth  quarter of 1996.  The loss for the fourth  quarter of 1997 was $3.1
million,  or

                                      -6-

<PAGE>

$0.20 per share, compared to a net loss of $3.1 million, or $0.29 per share, for
the fourth quarter of 1996.  The Company  reported that in the fourth quarter of
1997, sales in the United States increased 9% from the third quarter of 1997 and
sales in Japan remained constant at almost $500,000.

         Revenue for the year ended December 31, 1997 was $9.8 million, compared
to $3.8  million for the year ended  December  31,  1996.  The loss for 1997 was
$16.5 million,  or $1.29 per share on 12.8 million  average shares  outstanding,
compared  to a net loss of $13.5  million,  or $1.30 per  share on 10.4  million
average shares  outstanding  for 1996. The 1997 results  include a one-time $2.1
million  cost of goods charge  relating to the  consolidation  of  manufacturing
facilities to the Company's California headquarters,  which was completed in the
fourth quarter of 1997. There were approximately 15.2 million shares outstanding
at December 31, 1997.

         As of December 31, 1997,  VidaMed's cash and cash equivalents  stood at
$8.0 million. In January 1998, the Company arranged a $1.5 million 42-month term
loan  with  Silicon  Valley  Bank  to  finance  the  costs  incurred  in 1997 of
establishing the Company's  manufacturing  facility in California.  In addition,
the Company has established a $3 million working capital line of credit facility
with Silicon Valley Bank.

                                  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 VidaMed TUNA System.  The Company has
experienced significant operating losses since inception and, as of December 31,
1997, had an accumulated deficit of $68.3 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 9 to 18  months  as it
continues  to expend  substantial  resources in  expanding  marketing  and sales
activities,  funding clinical trials in support of regulatory and  reimbursement
approvals 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. VidaMed's TUNA Procedure 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 with the clinical efficacy of the
TUNA Procedure 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 local  Medicare  Medical  Directors  who adopt

                                      -8-

<PAGE>

Medicare reimbursement guidelines based on current procedure terminology ("CPT")
codes  effective  January 1, 1998, 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.  The Company has recently received  approvals by the Ministry of Health
and Welfare in Japan, and by the British  Provident  Association Ltd.  ("BUPA"),
the largest private health care insurer in the United Kingdom.

         Regardless of the type of  reimbursement  system,  the Company believes
that  physician  advocacy of the VidaMed  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.  In the United  States,  TUNA
Procedures are currently being  reimbursed by certain  private payors.  However,
due  to  the  age  of  the  typical  BPH  patient,   Medicare  reimbursement  is
particularly  critical for widespread market acceptance of the TUNA Procedure in
the United States. CPT Code #53852,  covering the physician fee component of the
TUNA  Procedure,  was  included in the 1998  edition of CPT codes  which  became
effective January 1, 1998. If adopted by local Medicare Medical Directors,  this
code should  enhance the  reimbursement  process for  physicians  performing the
VidaMed TUNA Procedure in an outpatient  hospital  environment.  The CPT code is
active in over 30 states, although to date only a small number of the states has
a formal written policy  guideline  covering  reimbursement  of the VidaMed TUNA
Procedure.  Further,  national Medicare reimbursement of TUNA Procedure costs in
an office  setting at an adequate  level will require  completion  by the Health
Care Financing  Administration  ("HCFA") of a review of the cost and efficacy of
the TUNA  Procedure.  Such cost and efficacy review may involve an assessment of
clinical data with up to five-year patient follow-up.  Accordingly, there can be
no assurance that office-based  reimbursement for the Company's products will be
available  in  the  United  States  or in  international  markets  under  either
governmental  or private  reimbursement  systems  at  adequate  levels,  or that
physicians   will  support   reimbursement   for  the  VidaMed  TUNA  Procedure.
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,   including  in  particular  Medicare
reimbursement  in the United  States,  or adverse  changes in  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 Procedure, in connection with
obtaining necessary  regulatory and reimbursement  approvals or in other aspects
of the  Company's  business.  Although  the  Company  believes  that  the  funds
available through the Company's  existing bank credit  facilities,  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 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.  Future debt  financings  may require the Company to pledge assets
and to comply with financial and operational covenants.

                                      -9-

         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

                                      -10-

<PAGE>

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.  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 VidaMed 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.

         The  Company's   distributor  in  Japan,  Century  Medical,   Inc.,  is
responsible  for  management  of clinical  trials and obtaining  regulatory  and
reimbursement  approval  for the  TUNA  System.  Such  regulatory  approval  was
received from the Japanese Ministry of Health and Welfare in July 1997. However,
failure  to obtain  market  acceptance  for the TUNA  Procedure  in Japan  could
preclude the commercial  viability of the Company's  products in Japan and could
have a material adverse effect on the Company's  business,  financial  condition
and results of operations.

         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,  could have a material
adverse  effect on the Company's  business,  financial  condition and results of
operations.

         The Company's  United  Kingdom  manufacturing  of the VidaMed TUNA hand
piece had been only in limited quantities. The Company has limited experience in
manufacturing  its  products  in  commercial

                                      -11-

<PAGE>

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 System hand
piece's needle assembly.  As a result,  a substantial  portion of hand pieces 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.  In
addition,  the Company's new Fremont  facility has capacity to  manufacture  the
TUNA System hand piece and the Company is currently in the process of qualifying
this facility under FDA good  manufacturing  practice  regulations and under ISO
9000 standards. The Company is consolidating manufacturing in Fremont. Inability
to obtain FDA good  manufacturing  practice and ISO 9000  qualification  for the
Fremont facility, or problems associated with the consolidation of manufacturing
at  such  facility,  could  have a  material  adverse  effect  on the  Company's
business.

         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 34 United  States  patents and 34 foreign  patents
covering a method of prostate  ablation  using the  VidaMed  TUNA System and the
design of the TUNA  System.  The Company  currently  has 21 patent  applications
pending in the United States and 56 corresponding patent applications pending 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 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 United  States  Patent  and
Trademark Office ("USPTO") interference proceedings. 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.

                                      -12-

<PAGE>

         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 product concepts for the treatment of snoring and sleep apnea
that have been assigned to an unrelated third party and certain product concepts
in the  gynecology  field that have been  licensed  to another  unrelated  third
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,
and VidaMed will have no rights or ownership interests with respect thereto.

         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

                                      -13-

<PAGE>

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  Resale  Warrants  or the  Shelf  Warrants;
Arbitrary  Determination of Purchase Price;  Price Volatility.  The Company does
not intend to apply for the listing of the Resale Warrants or the Shelf Warrants
on any  exchange.  Accordingly,  there has been no public  market for the Resale
Warrants or the Shelf Warrants prior to the offering of the Resale  Warrants and
the Shelf Warrants,  and there can be no assurance that an active trading market
will  develop  in any of the Resale  Warrants  or the Shelf  Warrants  after any
offering  thereof.  The  exercise  price and terms of the Shelf  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 Shelf
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  Shelf  Warrants.  In
addition,  the exercise  price of the Resale  Warrants may not be  indicative of
prices that may prevail at any time or from time to time in a public  market for
the Resale Warrants.

         Legal  Restrictions  on Sales of Shares  Underlying the Resale Warrants
and the Shelf  Warrants.  The Resale Warrants and the Shelf 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
Resale  Warrants and the Shelf 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 Resale Warrants or the Shelf Warrants.
Although  the Company  has  undertaken  to use its best  efforts to have all the
shares of Common Stock  issuable  upon  exercise of the Resale  Warrants and the
Shelf  Warrants  registered  or qualified on or before the exercise  date and to
maintain a current  prospectus  relating  thereto  until the  expiration  of the
Resale Warrants and the Shelf  Warrants,  there can be no assurance that it will
be able to do so. The Resale  Warrants and the Shelf Warrants may be deprived of
value if a current prospectus  covering the shares of Common Stock issuable upon
the  exercise  of the  Resale  Warrants  and  the  Shelf  Warrants  is not  kept
effective.

                                 USE OF PROCEEDS

         None of the  proceeds  from  the  sale of the  Resale  Warrants  by the
Selling Warrant Holders will be received by the Company.

         Unless otherwise specified in the applicable  Prospectus Supplement for
any offering of Shelf  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.


                             SELLING WARRANT HOLDERS

         The  Company  sold  2,517,652  shares  of Common  Stock and the  Resale
Warrants to the Selling  Warrant  Holders in private  transactions  in September
1997. Such shares of Common Stock, and the shares of Common Stock underlying the
Resale  Warrants,  were registered  under a Registration  Statement filed by the
Company on September 24, 1997 (File No.  333-36327) (the "Previous  Registration
Statement").  The  Resale  Warrants  offered  hereby  are  registered  under the
Registration Statement of which this Prospectus forms a part.

<TABLE>
         The following table provides the names of the Selling Warrant  Holders,
the  number  of  shares  of  Common  Stock  held by each of them at the time the
Previous Registration  Statement was declared effective and the number of Resale
Warrants being offered by each of them hereby.  After completion of the offering
of the Resale  Warrants,  assuming all the Resale  Warrants  offered  hereby are
sold, and, in the event any of the Resale  Warrants are exercised,  assuming the
shares of Common Stock issued upon such exercise are sold,  and assuming all the
shares of Common Stock registered under the Previous Registration  Statement are
sold, no Selling Warrant Holder will hold any securities of the Company,  except
as set forth in the footnotes below.

         No  Selling  Warrant  Holder  has held any  position,  office  or other
material  relationship with the Company or any of its predecessors or affiliates
within the past three years.

         Each  Selling  Warrant  Holder has  represented  to the Company that it
purchased  the Resale  Warrants  for  investment,  with no present  intention of
distribution.  However,  in recognition of the fact that investors,  even though
purchasing the Resale Warrants for investment,  may wish to be legally permitted
to sell their Resale Warrants when they deem appropriate,  the Company has filed
with the Commission  under the Securities  Act the  Registration  Statement with
respect  to the  resale of the Resale  Warrants  from time to time in  privately
negotiated transactions,  through the writing of options on the Resale Warrants,
or through a combination of the foregoing. The Company has agreed to prepare and
file such  amendments and  supplements to the  Registration  Statement as may be
necessary to keep the Registration  Statement  effective for four years from the
date of closing of the issuance of the Resale Warrants.


                              PLAN OF DISTRIBUTION

         The sale of the Resale  Warrants by the Selling  Warrant Holders may be
effected from time to time in transactions in privately negotiated transactions,
through the writing of options on the Resale Warrants,  or through a combination
of such methods of sale, at fixed prices,  that may be changed, at market prices
prevailing at the time of sale,  at prices  relating to such  prevailing  market
prices or at  negotiated  prices.  The Selling  Warrant  Holders may effect such
transactions  by selling the Resale Warrants to or through  broker-dealers,  and
such  broker-dealers  may  receive   compensation  in  the  form  of  discounts,
concessions  or  commissions   from  the  Selling  Warrant  Holders  and/or  the
purchasers of the Resale Warrants for whom such broker-dealers may act as agents
or to whom they may sell as  principals,  or both  (which  compensation  as to a
particular  broker-dealer  may be in  excess  of  customary  compensation).  Any
broker-dealer may act as a broker-dealer on behalf of one or more of the Selling
Warrant  Holders  in  connection  with the  offering  of  certain  of the Resale
Warrants by the Selling Warrant Holders.

         The  Selling  Warrant  Holders  and  any   broker-dealers  who  act  in
connection  with the sale of the Resale  Warrants  hereunder may be deemed to be
"underwriters"  within the meaning of Section 2(11) of the  Securities  Act, and
any commissions received by them and profit on any resale of the Resale Warrants
as principal might be deemed to be underwriting  discounts and commissions under
the  Securities  Act.  The Company has agreed to indemnify  the Selling  Warrant
Holders against certain liabilities,  including liabilities under the Securities
Act.

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

                                      -16-

<PAGE>

         The  distribution of the Shelf  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 Shelf  Securities,  underwriters  may
receive  compensation  from the Company or from purchasers of Shelf  Securities,
for whom  they may act as  agents,  in the form of  discounts,  concessions,  or
commissions.  Underwriters  may sell Shelf  Securities to or through dealers and
such dealers may receive compensation in the form of 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 Shares  sold  pursuant  to a  Prospectus  Supplement  and any Shelf
Warrant Shares issuable upon exercise of any Shelf Warrants issued 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
Shelf  Warrants  will be a new issue with no  established  trading  market.  The
Company may elect to list any series of Shelf  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 Shelf 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 Shelf
Securities.

         Under agreements the Company may enter into, underwriters,  dealers and
agents who participate in the  distribution of Shelf  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.


                            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 February 5, 1998,  15,231,101
shares of Common Stock were  outstanding,  held of record by  approximately  271
stockholders.  No shares of the Preferred Stock were  outstanding as of February
5, 1998,  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.

Resale Warrants

         The following  summary  description  of the Resale  Warrants sets forth
certain  general terms and provisions of the Resale  Warrants,  but such summary
does not purport to be complete and is qualified in all respects by reference to
the actual text of the Resale Warrant.

         Exercise  Price  and  Terms.  Each  Resale  Warrant  will  entitle  the
registered holder thereof to purchase, for three years commencing on the date of
issuance,  a fixed number of shares of Common Stock at $6.33 per share,  subject
to adjustment in accordance with the anti-dilution and other provisions referred
to below.  The holder of any Resale Warrant will be able to exercise such Resale
Warrant by  surrendering  the  certificate  representing  the Resale  Warrant to
American Securities Transfer,  Inc. (the "Warrant Agent"), with the

                                      -17-

<PAGE>

subscription form thereon properly completed and executed, together with payment
of the exercise price. The Resale Warrants may be exercised at any time in whole
or in part at the  applicable  exercise  price  until  expiration  of the Resale
Warrants.  No  fractional  shares will be issued upon the exercise of the Resale
Warrants.

         The exercise price of the Resale  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 Resale  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
order to enable  warrant  holders  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 Resale Warrant.

         Transfer,  Exchange  and  Exercise.  The  Resale  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
Resale  Warrants  will become  wholly void and of no value.  If a market for the
Resale Warrants  develops,  the holder may sell the Resale  Warrants  instead of
exercising  them.  There can be no  assurance,  however,  that a market  for the
Resale  Warrants  will  develop or continue  and the Company  does not intend to
apply for the listing of the Resale Warrants on any exchange.

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

         The Resale 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 Resale  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 Resale Warrants. Although the
Company has  undertaken to use its best efforts to have all the shares of Common
Stock issuable upon exercise of the Resale  Warrants  registered or qualified on
or before  the  exercise  date and to  maintain  a current  prospectus  relating
thereto until the expiration of the Resale  Warrants,  there can be no assurance
that it will be able to do so.

Shelf Warrants

         The  following  summary  description  of the Shelf  Warrants sets forth
certain  general  terms  and  provisions  of the  Shelf  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
Shelf Warrant.

         Exercise  Price  and  Terms.   Each  Shelf  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 Shelf  Warrant will be able to
exercise such Shelf Warrant by  surrendering  the certificate  representing  the
Shelf 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.

                                      -18-

<PAGE>

The  Shelf  Warrants  may be  exercised  at any  time in whole or in part at the
applicable exercise price until expiration of the Shelf Warrants.  No fractional
shares will be issued upon the exercise of the Shelf Warrants.

         The exercise  price of the Shelf 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 Shelf  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
order to enable  warrant  holders  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 Shelf Warrant.

         Transfer,  Exchange  and  Exercise.  The  Shelf  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
Shelf  Warrants  will become  wholly  void and of no value.  If a market for the
Shelf  Warrants  develops,  the  holder may sell the Shelf  Warrants  instead of
exercising them. There can be no assurance, however, that a market for the Shelf
Warrants  will  develop or continue and the Company does not intend to apply for
the listing of the Shelf Warrants on any exchange.

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

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

         The Shelf 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 Shelf  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 Shelf Warrants.  Although the
Company has  undertaken to use its best efforts to have all the shares of Common
Stock issuable upon exercise of the Shelf Warrants registered or qualified on or
before the exercise date and to maintain a current  prospectus  relating thereto
until the  expiration of the Shelf  Warrants,  there can be no assurance that it
will be able to do so.
