                 Purchase and Sale of Common Stock and Warrants

         1.1 Purchase and Sale of Common Stock.  Each  Purchaser,  severally and
not  jointly,  agrees to purchase  from the Company,  and the Company  agrees to

Warrant,  the form of which is  attached  hereto  as  Exhibit  B,  entitles  the
registered  holder  thereof  to  purchase  Common  Stock at a price of $6.33 per
share,  subject to adjustment in certain  circumstances,  commencing on the date

<PAGE>


                  Representations and Warranties of the Company

        The Company represents and warrants to the Purchasers as follows:

         3.1  Organization  and  Standing.  The  Company is a  corporation  duly
organized and validly existing under, and by virtue of, the laws of the State of
Delaware  and is in good  standing as a domestic  corporation  under the laws of
said state,  and has the  requisite  corporate  power and  authority  to own its
properties  and to carry on its business as now being  conducted.  Other than as
disclosed  in  the  SEC  Documents  (as  defined  below),  the  Company  has  no
subsidiaries  or direct  or  indirect  ownership  in any  firm,  corporation  or
business  which either,  individually  or in the  aggregate,  is material to the
business of the Company.  The Company is qualified to do business and is in good
standing as a foreign  corporation in every  jurisdiction in which its ownership
of property or conduct of business  requires it so to be qualified  and in which
the failure to so qualify would have a material  adverse effect on the financial
condition or business of the Company.

         3.2 Corporate Power; Authorization. The Company has all requisite legal
and corporate power and authority and has taken all requisite  corporate  action
to duly  authorize,  execute and deliver this  Agreement,  to sell and issue the
Shares and the  Warrants  and to carry out and  perform  all of its  obligations
under and contemplated by this Agreement. This Agreement has been duly exe cuted
and delivered by an authorized officer of the Company and constitutes the legal,
valid and binding obligation of the Company,  enforceable in accordance with its
terms, except as limited by applicable bankruptcy, insolvency, reorganization or
similar laws  relating to or affecting  the  enforcement  of  creditors'  rights
generally.

         3.3 Issuance and  Delivery.  The Shares and the Warrants have been duly
authorized,  and, when issued and delivered in compliance  with this  Agreement,
will be duly and validly  issued and  delivered and will be  outstanding,  fully
paid,  nonassessable and free and clear of all pledges, liens,  encumbrances and
restrictions, and will conform to the description thereof contained in the Regis
tration  Statement (or  incorporated by reference  therein).  The Warrant Shares
have been duly  authorized  and  reserved  for  issuance  upon  exercise  of the
Warrants, and such shares, when issued upon such exercise in accordance with the
terms  of  the  Company's   Certificate  of  Incorporation   and  the  Warrants,
respectively, and when the price is paid upon exercise of the Warrants, shall be
fully  paid  and  non-assessable.  No  preemptive  rights,  or other  rights  to
subscribe  for or  purchase,  exist with respect to the issuance and sale of the
Securities by the Company  pursuant to this  Agreement.  No  stockholder  of the
Company has any right (which has not been waived or has not expired by reason of
lapse  of time  following  notification  of the  Company's  intent  to file  the
Registration  Statement)  to require  the  Company to  register  the sale of any
securities  owned by such holder under the  Securities  Act of 1933,  as amended
(the "Securities  Act"), in the Registration  Statement.  No further approval or
authority of the  stockholders  or the Board of Directors of the Company will be
required for the issuance and sale of the  Securities  to be sold by the Company
as contemplated herein.

         3.4 SEC Documents; Financial Statements; Subsequent Events. The Company
has filed in a timely manner all documents that the Company was required to file
with the Securities and Exchange Commission ("SEC") under Sections 13, 14(a) and

during the twelve (12) months preceding the date of this Agreement and all rules
and regulations thereunder.  As of their respective filing dates, all docu ments
filed by the Company with the SEC (the "SEC Documents") complied in all material
respects  with the  requirements  of the Exchange Act or the  Securities  Act of
1933,  as  amended  (the  "Securities  Act"),  as  applicable  and all rules and
regulations  thereunder.  None of the SEC  Documents  con  tained,  as of  their
respective  dates,  any untrue  statement of material fact or omitted to state a
material fact required to be stated  therein or necessary to make the statements
made therein,  in light of the cir  cumstances  under which they were made,  not
misleading,  and such SEC  Documents,  when read as a whole,  do not contain any
untrue  statements  of a material  fact and do not omit to state a material fact
necessary to make the statements  therein,  in light of the circumstances  under
which they were made, not  misleading.  The financial  statements of the Company
included  in the  SEC  Documents  (the  "Financial  Statements")  comply  in all
material respects with applicable accounting requirements and with the published
rules and regulations of the SEC with respect thereto.  The Financial Statements
have  been  prepared  in  accordance  with  United  States  generally   accepted
accounting  principles  consistently  applied and fairly  present the  financial
position  of the  Company  and any  subsidiaries  at the dates  thereof  and the
results of the  Company's  operations  and cash flows for the periods then ended
(subject,  in  the  case  of  unaudited  statements,   to  normal  adjustments).
Subsequent to the date of the Company's most recently  filed SEC Documents,  the
Company, effective September 5, 1997, has repriced all outstanding stock options
having an exercise  price in excess of $4.813 to a new exercise  price of $4.813
per share.  In  addition,  by virtue of the  transactions  contemplated  by this
Agreement,  the number of shares of Common  Stock  issuable  pursuant to certain
outstanding warrants of the Company will increase by approximately 10,000 shares
and the exercise price under such warrants will be correspondingly adjusted.

         3.5 Governmental Consents. No consent, approval, order or authorization
of, or registration, qualification, designation, declaration or filing with, any
federal,  state, or local  governmental  authority on the part of the Company is
required in connection with the execution and delivery of this Agreement and the
consummation of the transactions  contemplated by this Agree ment except for (a)
the filing of a Form D with respect to the issuance of the  Securities  with the
SEC and (b) the filing of a Nasdaq National Market  Notification  Form (pursuant
to Rule 10b-17  promul  gated under the Exchange  Act) with the Nasdaq  National
Market, each of which will be filed in a timely manner.

         3.6 Exempt  Transactions.  Subject to the  accuracy of the  Purchasers'
representations  and warranties in Section 4 of this Agreement,  the offer, sale
and issuance of the  Securities in conformity  with the terms of this  Agreement
constitute  transactions exempt from the registration  requirements of Section 5
of the Securities Act and from the registration or qualification requirements of
the laws of any applicable state or United States jurisdiction.

the  above  securities  of the  Company  were  issued  in  compliance  with  all

or subject to any preemptive rights or other rights to subscribe for or purchase
securities.  No  holder  of any  security  of the  Company  is  entitled  to any
preemptive or similar rights to purchase any securities of the Company.

         3.10  Litigation.   There  are  no  actions,   suits,   proceedings  or
investigations  pending or, to the best of the Company's  knowledge,  threatened
against  the  Company  or any of  its  properties  before  or by  any  court  or
arbitrator or any governmental  body, agency or official in which there is a rea
sonable  likelihood (in the judgment of the Company) of an adverse decision that
(a) would have a material  adverse effect on the Company's  properties or assets
or the  business  of the  Company  as  presently  conducted  or  proposed  to be
conducted  or (b) would  impair  the  ability  of the  Company to perform in any
material  respect its obligations  under this  Agreement.  The Company is not in

                                    Section 4

           Representations, Warranties and Covenants of the Purchasers

         Each Purchaser,  severally and for itself only,  hereby  represents and
warrants to the Company as follows:

         4.1  Authorization.  (i) The  Purchaser  has all  requisite  legal  and
corporate or other power and capacity and has taken all  requisite  corporate or
other action to execute and deliver this Agree ment, to purchase the  Securities
to be purchased by it and to carry out and perform all of its obliga tions under
this Agreement; and (ii) this Agreement constitutes the legal, valid and binding
obliga tion of the Purchaser,  enforceable in accordance with its terms,  except
(a) as limited by applicable bankruptcy, insolvency,  reorganization, or similar
laws relating to or affecting the enforcement of creditors' rights generally and
(b) as limited by equitable principles generally.

         4.2 Investment Experience. The Purchaser is an "accredited investor" as
defined in Rule 501(a) under the  Securities  Act. The Purchaser is aware of the
Company's business affairs and financial condition and has had access to and has
acquired  sufficient  information  about the  Company to reach an  informed  and
knowledgeable  decision  to  acquire  the  Securities.  The  Purchaser  has such
business  and  financial  experience  as is required to give it the  capacity to
protect its own interests in connection with the purchase of the Securities.

         4.3 Investment  Intent.  The Purchaser is purchasing the Securities for
its own account as  principal,  for  investment  purposes  only,  and not with a
present view to, or for, resale,  distribution or fractionalization  thereof, in
whole or in part,  within the  meaning  of the  Securities  Act.  The Pur chaser
understands that its acquisition of the Securities has not been registered under
the Securities Act or registered or qualified under any state  securities law in
reliance on specific  exemptions  therefrom,  which  exemptions may depend upon,
among other things, the bona fide nature of the Purchaser's investment intent as
expressed  herein.  The  Purchaser  has  completed or caused to be completed the
Purchaser  Questionnaire attached hereto as Appendix I for use in preparation of
the  Registration  Statement  (as defined  below),  and the  responses  provided
therein  shall be true and correct as of the  Closing  Date and will be true and
correct as of the effective date of the Registration


                                       -7-


<PAGE>



Statement. The Purchaser will not, directly or indirectly,  offer, sell, pledge,
transfer or  otherwise  dispose of (or  solicit  any offers to buy,  purchase or
otherwise  acquire or take a pledge of) any of the Shares,  the Warrants and the
Warrant Shares except in compliance  with the Securities  Act, and the rules and
regulations promulgated thereunder.

         4.4  Registration  or Exemption  Requirements.  The  Purchaser  further
acknowledges  and understands that the Securities may not be resold or otherwise
transferred  except in a  transaction  registered  under the  Securities  Act or
unless  an  exemption  from  such  registration  is  available.   The  Purchaser
understands that the certificate(s)  evidencing the Securities will be imprinted
with a legend that prohibits the transfer of such securities unless (i) they are
registered or such  registration  is not  required,  and (ii) if the transfer is
pursuant  to an  exemption  from  registration  other  than  Rule 144  under the
Securities  Act and, if the Company  shall so request in writing,  an opinion of
counsel  reasonably  satisfactory  to the Company is obtained to the effect that
the transaction is so exempt.

         4.5 Restriction on Short Sales.  The Purchaser  represents and warrants
to and  covenants  with the Company that the  Purchaser has not engaged and will
not  engage  in any  short  sales of the  Company's  Common  Stock  prior to the
effectiveness of the Registration Statement,  except to the extent that any such
short sale is fully  covered by shares of Common  Stock of the Company  owned by
such Purchaser other than the Shares or the Warrant Shares.

         4.6 No Legal, Tax or Investment Advice. The Purchaser  understands that
nothing in this Agreement or any other  materials  presented to the Purchaser in
connection  with  the  purchase  of the  Securities  constitutes  legal,  tax or
investment  advice.  The Purchaser has consulted such legal,  tax and investment
advisors as it, in its sole  discretion,  has deemed necessary or appropriate in
con nection  with its purchase of the  Securities  and  understands  that Musket
Research Associates (the "Placement Agent") has acted as placement agent for the
Company and not in any of the foregoing capacities on behalf of the Purchaser.

                                    Section 7

                      Affirmative Covenants of the Company

         The Company hereby covenants and agrees as follows:

         7.1      Registration Requirements.

                  (a)  The  Company  shall,  subject  to  receipt  of  necessary
information from the Purchasers,  prepare and file a registration statement with
the SEC under the  Securities  Act as soon as reasonably  practicable  after the
Closing to  register  the resale of the  Shares,  the  Warrants  and the Warrant
Shares by the  Purchasers,  and the Company shall use its best efforts to secure
the  effective  ness  of such  registration  statement  as  soon  as  reasonably
practicable  thereafter.  The  Purchasers  acknowledge  that the  Company may be
required to register the Warrants on a separate registration statement, in which
case the Company will first file a registration statement relating to the Shares
and the Warrant Shares. For purposes hereof,  the term "Registration  Statement"
shall  refer to any and all  registration  statements  filed for the  purpose of
registering  the Shares,  the Warrant  Shares and the  Warrants,  including  any
prospectus(es)  constituting a part thereof and together with any amendments and
supplements thereto.

                  (b) The  Company  shall  pay  all  Registration  Expenses  (as
defined below) in connection with any registration,  qualification or compliance
hereunder,  and the Purchasers shall pay all Selling Expenses (as defined below)
and  other  expenses  that  are  not  Registration  Expenses  relat  ing  to the
Securities  resold by the  Purchasers.  "Registration  Expenses"  shall mean all
expenses, except for Selling Expenses, incurred by the Company in complying with
the registration provisions herein described, including, without limitation, all
registration,  qualification and filing fees,  printing  expenses,  escrow fees,
fees and  disbursements  of counsel for the Company,  blue sky fees and expenses
and the  expense of any  special  audits  incident  to or  required  by any such
registration.   "Selling   Expenses"   shall  mean  all   selling   commissions,
underwriting fees and stock transfer taxes applicable to the Securities.

                  (c) In the case of the  registration  effected  by the Company
pursuant to these registration provisions, the Company will use its best efforts
to: (i) keep such  registration  effective  until the  earlier of (A) the fourth
anniversary  of the Closing Date,  (B) such date as all of the  Securities  have
been resold or (C) such time as all of the Securities held by the Purchasers can
be  sold  within  a  given  three-month   period  without  compliance  with  the
registration  requirements  of the Securities Act pursuant to Rule 144(k);  (ii)
prepare and file with the SEC such amendments and  post-effective  amendments to

and as so  supplemented  to be  filed  pursuant  to Rule  424  (or  any  similar
provisions  then in force)  under  the  Securities  Act;  (iv)  comply  with the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
securities covered by the Registration Statement during the applicable period in
accordance  with the intended  methods of disposition by the sellers thereof set
forth in the  Registration  Statement  as so  amended or such  prospectus  as so
supplemented;  (v)  furnish  such  number of  prospectuses  and other  documents
incident thereto, including any amendment of or supplement to the prospectus, as
a Purchaser  from time to time may  reasonably  request,  and the Company hereby
consents to the use of such prospectus or each amendment and supplement  thereto
by each of the selling  holders of Securities and the  underwriters,  if any, in
connection  with  the  offering  and  sale  of the  Securities  covered  by such
prospectus or any amendment or supplement thereto; (vi) cause the Shares and the
Warrant  Shares to be  listed on each  securities  exchange  and  quoted on each
quotation  service on which  similar  securities  issued by the Company are then
listed or quoted and  maintain  the  listing of the Shares and  Warrant  Shares;
(vii)  provide a transfer  agent and  registrar  for all  Securities  registered

sold and (B) all other states  specified in writing by a Purchaser,  provided as
to clause (B), however,  that the Company shall not be required to qualify to do
business or consent to service of process in any state in which it is not now so
qualified or has not so consented.

                  (d) The Company shall furnish to each Purchaser upon request a
reasonable  number  of  copies  of a  supplement  to or  an  amendment  of  such
prospectus as may be necessary in order to  facilitate  the public sale or other
disposition of all or any of the Securities held by such Purchaser.

                  (e) With a view to  making  available  to the  Purchasers  the
benefits of Rule 144  promulgated  under the Securities Act ("Rule 144") and any
other rule or  regulation  of the SEC that may at any time permit a Purchaser to
sell Securities to the public without registration or pursuant to a registration
on Form S-3,  the  Company  covenants  and agrees  to: (i) make and keep  public
information  available,  as those terms are  understood and defined in Rule 144,
until the earlier of (A) the fourth  anniversary  of the  effective  date of the
Registration Statement or (B) such date as all of the Securities shall have been
resold;  (ii)  file  with the SEC in a  timely  manner  all  reports  and  other
documents required of the Company under the Securities Act and Exchange Act; and
(iii) furnish to each Purchaser upon request, as long as such Purchaser owns any

reporting requirements of the Securities Act and the Exchange Act, (B) a copy of
the most recent  annual or quarterly  report of the Company,  and (C) such other
information as may be reasonably  requested in order to avail a Purchaser of any
rule or  regulation  of the SEC that permits the selling of any such  Securities
without registration or pursuant to such Form S-3.

                  (f) The Company shall notify each Purchaser, if such Purchaser
has registered  Securities in a Registration  Statement which remain unsold, and
(if  requested by such  Purchaser)  confirm  such notice in writing,  (i) when a
prospectus or any  prospectus  supplement or  post-effective  amendment has been
filed,  and, with respect to the  Registration  Statement or any  post-effective
amendment, when the same has become effective, (ii) of any request by the SEC or
any  other  federal  or  state  governmental  authority  during  the  period  of
effectiveness of the Registration Statement for amendments or supplements to the
Registration  Statement  or related  prospectus  or for  additional  information
relating to the Registration Statement,  (iii) of the issuance by the SEC or any
other federal or state  governmental  authority of any stop order suspending the
effectiveness of the Registration Statement or the initiation of any proceedings
for that purpose,  (iv) of the receipt by the Company of any  notification  with
respect to the suspension of the  qualification or exemption from  qualification
of any of the  Securities  for sale in any  jurisdiction  or the  initiation  or
threatening  of any  proceeding  for such  purpose,  (v) of the happening of any
event which makes any statement  made in the  Registration  Statement or related
prospectus or any document  incorporated or deemed to be incorporated therein by
reference  untrue in any  material  respect or which  requires the making of any
changes in the Registration  Statement or prospectus so that, in the case of the
Registration  Statement,  it will not contain any untrue statement of a material
fact or omit to state  any  material  fact  required  to be  stated  therein  or
necessary to make the statements therein not misleading, and that in the case of
the prospectus,  it will not contain any untrue  statement of a material fact or
omit to state any material  fact or omit to state any material  fact required to
be stated therein or necessary to make the statements  therein,  in the light of
the  circumstances  under which they were made, not misleading,  and (vi) of the
Company's  reasonable  determination  that  a  post-effective  amendment  to the
Registration Statement would be appropriate.

                  (g) The Company may, upon written  notice to the Purchasers of
(i) the  happening  of any event of the kind  described  in Section  7.1(f)(ii),
7.1(f)(iii),  7.1(f)(iv),  7.1(f)(v) or  7.1(f)(vi)  hereof or (ii) that, in the
judgement of the Company's Board of Directors, it is advisable to suspend use of
the  prospectus  for  a  discrete  period  of  time  due  to  pending  corporate
developments,  public  filings  with  the  SEC or  similar  events,  discontinue
disposition of Securities  covered by the  Registration  Statement or prospectus
until copies of the supplemented or amended  prospectus  contemplated by Section
7.1(i) hereof are  distributed  to the  Purchasers,  or until the Purchasers are
advised in writing by the Company that the use of the applicable  prospectus may
be  resumed,  and the  Purchasers  have  received  copies of any  additional  or
supplemental  filings that are incorporated or deemed  incorporated by reference
in such  prospectus.  The  Company  shall not  suspend  use of a  prospectus  or
Registration Statement under this Section 7.1(g) for more than 30 days at a time
and more  than  twice in any  12-month  period.  Any  period  for which use of a
prospectus  or  Registration  Statement is suspended  under this Section  7.1(g)
shall be added to the time for which the Company is  required  to  maintain  the
effectiveness  of  such   Registration   Statement,   including  the  prospectus
constituting a part thereof, under Section 7.1(c).

                  (h) The Company  shall use every  reasonable  effort to obtain
the withdrawal of any order  suspending the  effectiveness  of the  Registration
Statement, or the lifting of any suspension

                                      -12-


<PAGE>



of the qualification (or exemption from  qualification) of any of the Securities
for sale in any jurisdiction, at the earliest possible moment.

                  (i) The  Company  shall,  upon  the  occurrence  of any  event
contemplated by Section 7.1(f)(v) or 7.1(f)(vi)  above,  prepare a supplement or
post-effective  amendment to the  Registration  Statement or a supplement to the
related prospectus or any document incorporated therein by reference or file any
other  required  document so that, as thereafter  delivered to the purchasers of
the Securities being sold thereunder, such prospectus will not contain an untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances under which they were made, not misleading.

         7.2      Indemnification and Contribution.

                  (a) The Company  agrees to  indemnify  and hold  harmless  the
Purchasers  from and against  any losses,  claims,  damages or  liabilities  (or
actions or  proceedings  in respect  thereof) to which the Purchasers may become
subject (under the Securities Act or otherwise) insofar as such losses,  claims,
damages or liabilities (or actions or proceedings in respect  thereof) arise out
of, or are based upon, any untrue  statement or alleged untrue  statement of any
material  fact  contained  in  the  Registration  Statement  or  any  prospectus
(preliminary or final), as amended on the applicable date thereof,  or arise out
of or are  based  upon the  omission  or  alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein  not  misleading,  or arise out of any failure by the Company to fulfill
any  undertaking  included  in the  Registration  Statement  or  any  prospectus
(preliminary  or final),  as amended on the  applicable  date  thereof,  and the
Company  will,  as incurred,  reimburse  the  Purchasers  for any legal or other
expenses reasonably incurred in investigating,  defending or preparing to defend
any such action, proceeding or claim; provided,  however, that the Company shall
not be liable in any such case to the extent  that such loss,  claim,  damage or
liability arises out of, or is based upon (i) an untrue statement or an omission
made in such  Registration  Statement in reliance  upon and in  conformity  with
written  information  furnished to the Company by or on behalf of such Purchaser
specifically for use in preparation of the Regis tration Statement,  or (ii) any
untrue  statement or the omission of a material fact in any  prospectus  that is
corrected in any subsequent  prospectus  that was delivered to a Purchaser prior
to the pertinent sale or sales by such Purchaser.

                  (b) Each  Purchaser,  severally  and not  jointly,  agrees  to
indemnify  and hold  harmless the Company  from and against any losses,  claims,
damages or liabilities  (or actions or proceedings in respect  thereof) to which
the Company may become subject  (under the Securities Act or otherwise)  insofar
as such losses,  claims,  damages or  liabilities  (or actions or proceedings in
respect  thereof) arise out of, or are based upon (i) an untrue  statement or an
alleged untrue statement of a material fact made in such Registration  Statement
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading, in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by or on behalf of such Purchaser specifically for use in preparation of
the Registration Statement,

                                      -13-


<PAGE>



provided, however, that a Purchaser shall not be liable in any such case for any
untrue statement or alleged untrue statement or the omission or alleged omission
that has been corrected, in writing, by such Purchaser, delivered to the Company
before the sale from which such loss occurred,  or (ii) any untrue  statement or
alleged untrue  statement or the omission or alleged  omission in any prospectus
that is corrected in any subsequent prospectus that was delivered to a Purchaser
prior to the  pertinent  sale or sales by such  Purchaser,  and such  Purchaser,
severally  and not jointly,  will,  as incurred,  reim burse the Company for any
legal or other  expenses  reasonably  incurred in  investigating,  defending  or
preparing to defend any such action,  proceeding  or claim;  provided,  however,
that each  Purchaser's  indemnification  obligation  shall be limited to the net
proceeds received from its sale of the Securities.

                  (c)  Promptly  after  receipt by any  indemnified  person of a
notice of a claim or the  beginning of any action in respect of which  indemnity
is to be sought  against an  indemnifying  per son pursuant to this Section 7.2,
such indemnified person shall notify the indemnifying  person in writing of such
claim or of the commencement of such action, and, subject to the provisions here
inafter stated,  in case any such action shall be brought against an indemnified
person  and the  indemnifying  person  shall  have been  notified  thereof,  the
indemnifying person shall be entitled to participate therein, and, to the extent
that it shall  wish,  to assume the defense  thereof,  with  counsel  reasonably
satisfactory  to the  indemnified  person.  After  notice from the  indemnifying
person to such  indemnified  person of the  indemnifying  person's  election  to
assume the defense thereof,  the indemnifying person shall not be liable to such
indemnified  person  for any  legal  expenses  sub  sequently  incurred  by such
indemnified  person in connection with the defense thereof;  provided,  however,
that if there  exists or shall exist a conflict  of interest  that would make it
inappropriate in the reasonable  judgment of the indemnified person for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof,  the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person.

                  (d) If the indemnification provided for in this Section 7.2 is
unavailable  to or  insufficient  to hold  harmless an  indemnified  party under
subsection  (a) or (b)  above in  respect  of any  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect thereof)  referred to therein,
then each  indemnifying  party shall contribute to the amount paid or payable by
such  indemnified  party  as the  result  of such  losses,  claims,  damages  or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative  fault of the Company on the one hand and the Purchasers
on the other in connection  with the  statements or omissions  which resulted in
such losses,  claims, damages or liabilities (or actions in respect thereof), as
well as any other relevant equitable considerations. The relative fault shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to  information  supplied by the Company on the one hand
or a Purchaser on the other and the parties' relative intent, knowledge,  access
to information and opportunity to correct or prevent such statement or omission.
The Company and the Purchasers  agree that it would not be just and equitable if
contribution  pursuant  to this  subsection  (d)  were  determined  by pro  rata
allocation or by any other method of  allocation  which does not take account of
the equitable considerations

                                      -14-


<PAGE>



referred  to above in this  subsection  (d).  The  amount  paid or payable by an
indemnified party as a result of the losses, claims, damages, or liabilities (or
actions in respect  thereof)  referred to above in this  subsection (d) shall be
deemed  to  include  any legal or other  expenses  reasonably  incurred  by such
indemnified party in connection with  investigating or defending any such action
or claim.  Not  withstanding  the provisions of this subsection (d), a Purchaser
shall not be required to contribute  any amount in excess of the amount by which
the net amount  received by such  Purchaser  from the sale of the  Securities to
which such loss relates  exceeds the amount of any damages which such  Purchaser
has otherwise  been  required to pay by reason of such untrue or alleged  untrue
statement  or  omission  or alleged  omission.  No person  guilty of  fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be  entitled  to  contribution  from any person who was not guilty of such
fraudulent  misrepresentation.  Each Purchaser's  obligations in this subsection

<PAGE>


THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES  ACT OF  1933,  AS  AMENDED,  OR  QUALIFIED  UNDER  APPLICABLE  STATE
SECURITIES LAWS AND HAVE BEEN TAKEN FOR INVESTMENT  PURPOSES ONLY AND NOT WITH A
VIEW TO OR FOR SALE IN CONNECTION WITH ANY DISTRIBUTION  THEREOF. THE SECURITIES
MAY NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION AND
QUALIFICATION WITHOUT,  EXCEPT UNDER CERTAIN SPECIFIC LIMITED CIRCUMSTANCES,  AN
OPINION OF COUNSEL FOR THE HOLDER  REASONABLY  SATISFACTORY  TO THE COMPANY THAT
SUCH REGISTRATION AND QUALIFICATION ARE NOT REQUIRED.


                             STOCK PURCHASE WARRANT
                      To Purchase Shares of Common Stock of
                                  VIDAMED, INC.


         THIS  CERTIFIES  that,  for  value  received,  1 (the  "Investor"),  is
entitled, upon the terms and subject to the conditions hereinafter set forth, at
any time on or prior to the close of  business on the date three (3) years after
the date  hereof,  but not  thereafter,  to  subscribe  for and  purchase,  from
VIDAMED, INC. a Delaware corporation (the "Company"),  3 shares of Common Stock.
The  purchase  price of one share of Common  Stock under this  Warrant  shall be
$6.33 per  share.  The  purchase  price and the  number of shares  for which the
Warrant is exercisable  shall be subject to adjustment as provided herein.  This
Warrant has been issued  pursuant to a Purchase  Agreement  dated  September __,
1997  among  the  Company  and  the  Purchasers  named  therein  (the  "Purchase
Agreement").  Capitalized  terms not  defined  herein  shall  have the  meanings
ascribed to them in the Purchase Agreement.

         1. Title of  Warrant.  Prior to the  expiration  hereof and  subject to
compliance  with  applicable  laws,  this Warrant and all rights  hereunder  are
transferable,  in whole or in part,  at the  office or  agency  of the  Company,
referred  to in  Section 2  hereof,  by the  holder  hereof in person or by duly
authorized attorney, upon surrender of this Warrant together with the Assignment
Form annexed hereto properly endorsed.

         2.       Exercise of Warrant.

                  (a)  The  purchase  rights  represented  by this  Warrant  are
exercisable  by the registered  holder hereof,  in whole or in part, at any time
before the close of business on the date three (3) years after the date  hereof,
by delivery of the Notice of Exercise  form annexed  hereto duly executed at the
office of the Company, in Fremont, California (or such other office or agency of
the Company as it may  designate by notice in writing to the  registered  holder
hereof at the address of such holder appearing on the books of the Company), and
upon payment of the purchase price of the shares  thereby  purchased (by cash or
by check or bank  draft  payable  to the order of the  Company);  whereupon  the
holder of this Warrant shall be entitled to receive a certificate for the number
of shares of Common Stock so purchased.  The Company  agrees that if at the time
of the  surrender  of this  Warrant  and  purchase  the holder  hereof  shall be
entitled to  exercise  this  Warrant,  the shares so  purchased  shall be and be
deemed to be issued to such holder as the record  owner of such shares as of the
close of business on the date on which this Warrant shall have been exercised as
aforesaid.  If this Warrant  should be exercised in part only, the Issuer shall,
upon surrender of this Warrant,



<PAGE>



execute and deliver a new Warrant  evidencing the rights of the holder hereof to
purchase the balance of the Warrant Shares purchasable hereunder.

                  (b) In lieu of the cash  payment set forth in  paragraph  2(a)
above,  the Holder  shall have the right  ("Conversion  Right") to convert  this
Warrant in its entirety (without payment of any kind) into that number of shares
of Common  Stock equal to the  quotient  obtained by dividing  the Net Value (as
defined below) of the Shares  issuable upon exercise of this Warrant by the Fair
Market Value (as defined  below) of one share of Common  Stock.  As used herein,
(A) the Net Value of the Shares  means the  aggregate  Fair Market  Value of the
shares of Common Stock  subject to this  Warrant  minus the  aggregate  exercise
price; and (B) the Fair Market Value of one share of Common Stock means:

                           (i) if the exercise occurs at a time during which the
Company's  Common  Stock is traded on a national  securities  exchange or on the
Nasdaq National Market or the Nasdaq Small Cap Market,  the Fair Market Value of
one share of Common Stock means the average last  reported or closing sale price
for the  Company's  Common  Stock on such  exchange  or market  for the ten (10)
trading days ending one business day before the exercise of this Warrant;

                           (ii) if the exercise is in connection  with a merger,
sale of assets or other reorganization  transaction as described in Section 9(a)
below,  the Fair  Market  Value of one  share of  Common  Stock  means the value
received  by  the  holders  of the  Company's  Common  Stock  pursuant  to  such
transaction; and

                           (iii) in all other  cases,  the Fair Market  Value of
one share of Common  Stock shall be  determined  in good faith by the  Company's
Board of Directors.

                  (c)  Certificates  for  shares  purchased  hereunder  shall be
delivered  to the holder  hereof  promptly  after this  Warrant  shall have been
exercised as aforesaid.  The Company  covenants  that all shares of Common Stock
which may be issued upon the  exercise  of rights  represented  by this  Warrant
will, upon exercise of the rights represented by this Warrant, be fully paid and
nonassessable and free from all taxes, liens and charges in respect of the issue
thereof (other than taxes in respect of any transfer occurring contemporaneously
with such issue).

         3. No  Fractional  Shares  or  Scrip.  No  fractional  shares  or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant. With respect to any fraction of a share called for upon the exercise of
this  Warrant,  an amount  equal to such  fraction  multiplied  by the then Fair
Market Value shall be paid in cash to the holder of this Warrant.

         4. Charges, Taxes and Expenses.  Issuance of certificates for shares of
Common Stock upon the exercise of this Warrant  shall be made without  charge to
the holder hereof for any issue or transfer tax or other  incidental  expense in
respect of the  issuance of such  certificate,  all of which taxes and  expenses
shall be paid by the Company,  and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant;  provided,  however,  that in the event certificates for
shares of Common  Stock  are to be issued in a name  other  than the name of the
holder of this Warrant, this Warrant when surrendered

                                       -2-

<PAGE>



for exercise shall be accompanied  by the Assignment  Form attached  hereto duly
executed by the holder hereof.

         5. No Rights as Shareholders.  This Warrant does not entitle the holder
hereof to any voting  rights or other  rights as a  stockholder  of the  Company
prior to the exercise thereof.

         6.  Exchange  and Registry of Warrant.  This  Warrant is  exchangeable,
without  charge,  upon the  surrender  hereof  by the  registered  holder at the
above-mentioned office or agency of the Company, for a new Warrant of like tenor
and dated as of such exchange.

             The Company shall maintain at the above-mentioned  office or agency
a  registry  showing  the name and  address  of the  registered  holder  of this
Warrant. This Warrant may be surrendered for exchange,  transfer or exercise, in
accordance  with its terms,  at such  office or agency of the  Company,  and the
Company  shall be entitled to rely in all respects,  prior to written  notice to
the contrary, upon such registry.

         7. Loss, Theft,  Destruction or Mutilation of Warrant.  Upon receipt by
the  Company  of  evidence  reasonably  satisfactory  to it of the loss,  theft,
destruction  or  mutilation  of this  Warrant,  and in case of  loss,  theft  or
destruction,  of  indemnity  or  security  reasonably  satisfactory  to it,  and
cancellation of this Warrant, if mutilated,  the Company will make and deliver a
new  Warrant  of like tenor and dated as of such  cancellation,  in lieu of this
Warrant.

         8. Saturdays,  Sundays, Holidays, etc. If the last or appointed day for
the  taking of any action or the  expiration  of any right  required  or granted
herein  shall be a Saturday or a Sunday or shall be a legal  holiday,  then such
action may be taken or such right may be  exercised on the next  succeeding  day
not a legal holiday.

         9.  Early  Termination,   Antidilution   Adjustments  and  Registration
Statement Adjustments.

                  (a) Merger,  Sale of Assets, etc. In case of any consolidation
of the Company with, or merger of the Company into, any other corporation (other
than  a  consolidation  or  merger  in  which  the  Company  is  the  continuing
corporation and in which no change occurs in its outstanding  Common Stock),  or
in case of any sale or transfer of all or substantially all of the assets of the
Company,  or in the case of any statutory  exchange of  securities  with another
corporation  (including any exchange  effected in connection  with a merger of a
third  corporation  into the Company,  except where the Company is the surviving
entity and no change occurs in its  outstanding  Common Stock),  the corporation
formed by such consolidation or the corporation resulting from or surviving such
merger or the corporation which shall have acquired such assets or securities of
the  Company,  as the case may be,  shall  execute  and  deliver  to the  Holder
simultaneously  therewith a new Warrant,  satisfactory  in form and substance to
the Holder,  together  with such other  documents  as the Holder may  reasonably
request,  entitling the Holder  thereof to receive upon exercise of such Warrant
the kind and  amount  of  shares of stock  and  other  securities  and  property
receivable  upon such  consolidation,  merger,  sale,  transfer,  or exchange of
securities,  or upon the dissolution following such sale or other transfer, by a
holder of the number of shares of Common Stock purchasable upon

                                       -3-

<PAGE>



exercise of this Warrant immediately prior to such consolidation,  merger, sale,
transfer, or exchange. Such new Warrant shall contain the same basic other terms
and  conditions as this Warrant and shall  provide for  adjustments  which,  for
events subsequent to the effective date of such written instrument,  shall be as
nearly equivalent as may be practicable to the adjustments  provided for in this
Section 9. The above  provisions of this paragraph (a) shall  similarly apply to
successive consolidations,  mergers, exchanges, sales or other transfers covered
hereby. Notwithstanding the foregoing, in the event the consideration to be paid
to holders of Company capital stock in any transaction of the nature referred to
above  in  this  Section  9(a)  (a  "Transaction")  consists  of  cash  or  cash
equivalents,  then, provided that the Company shall have given the holder hereof
the notice  required by Section 10, this Warrant shall, to the extent it has not
been  exercised by the effective  date of such  Transaction,  terminate upon the
completion of such Transaction.

                  (b)  Dilutive  Financing  If at any time  prior  to the  first
anniversary of the date of issuance of this Warrant,  the Company effects a sale
of securities in a Financing  Transaction (as defined below) at a purchase price
per share that is less than the per share  purchase  price of the  Common  Stock
purchased  by the  Purchasers  pursuant to the  Investment  Agreement,  then the
purchase price for one share of Common Stock (the "Exercise  Price") pursuant to
this Warrant shall be reduced to the per share purchase price for the securities
issued  in  such  Purchase   Transaction.   For  purposes  hereof,  a  Financing
Transaction  shall consist of any sale or a series of sales of equity securities
or securities  convertible  into equity  securities of the Company for aggregate
consideration of at least $500,000.00.

                  (c) Increase in Warrant Coverage Re:  Registration  Statement.
In the event  that the  Registration  Statement  relating  to the Shares and the
Warrant  Shares that the  Company is  required to file with the SEC  pursuant to
Section 7.1 of the Purchase Agreement has not been declared effective by the SEC
by the 60th day following the Closing Date, the number of shares of Common Stock
of the Company  issuable  upon exercise of this Warrant  shall,  at the close of
business,  Washington,  D.C.  time on such 60th day, be  increased  to an amount
equal to 1.4 times the number of shares of Common Stock of the Company  issuable
upon exercise of this Warrant at the time of issuance hereof.

                  (d)  Reclassification,  etc. If the Company at any time shall,
by  subdivision,  combination  or  reclassification  of securities or otherwise,
change any of the securities to which  purchase  rights under this Warrant exist
into the same or a different number of securities of any class or classes,  this
Warrant shall thereafter  represent the right to acquire such number and kind of
securities as would have been issuable as the result of such change with respect
to the securities  which were subject to the purchase  rights under this Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change.  If shares of the Company's Common Stock are subdivided or combined into
a greater or smaller number of shares of Common Stock,  the purchase price under
this Warrant shall be  proportionately  reduced in case of subdivision of shares
or proportionately increased in the case of combination of shares, in both cases
by the ratio which the total number of shares of Common Stock to be  outstanding
immediately after such event bears to the total number of shares of Common Stock
outstanding immediately prior to such event.

                  (e)  Cash  Distributions.  Except  as  set  forth  herein,  no
adjustment on account of cash  dividends on the Company's  Common Stock or other
securities  purchasable  hereunder will be made to the purchase price under this
Warrant.

                  (f) Authorized  Shares.  The Company covenants that during the
period the Warrant is  outstanding,  it will  reserve  from its  authorized  and
unissued Common Stock a sufficient  number of shares to provide for the issuance
of Common Stock upon the exercise of any purchase rights under this Warrant. The
Company  further  covenants  that its issuance of this Warrant shall  constitute
full authority to its officers who are charged with the duty of executing  stock
certificates to execute and issue the necessary  certificates  for shares of the
Company's  Common  Stock upon the  exercise of the  purchase  rights  under this
Warrant.  The  Company  further  covenants  and agrees (i) that it will not,  by
amendment  of  its  Certificate  of  Incorporation  or  through  reorganization,
consolidation,  merger, dissolution or sale of assets, or by any other voluntary
act,  avoid  or seek to  avoid  the  observation  or  performance  of any of the
covenants,  stipulations or conditions to be observed or performed  hereunder by
the Company, (ii) promptly to take such action as may be required of the Company
to  permit  the  Holder  to  exercise  this  Warrant  and the  Company  duly and
effectively to issue shares of its Common Stock or other  securities as provided
herein upon the exercise  hereof and (iii) promptly to take all action  required
or provided herein to protect the rights of the Holder granted hereunder against
dilution.

                  (g) If the  Company  declares a dividend on Common  Stock,  or
makes  a  distribution  to  holders  of  Common  Stock,  and  such  dividend  or
distribution is payable or made in Common Stock or securities  convertible  into
or  exchangeable  for  Common  Stock,  or rights  to  purchase  Common  Stock or
securities  convertible  into or  exchangeable  for Common Stock,  the number of
shares  of Common  Stock  for  which  this  Warrant  may be  exercised  shall be
increased,  as of the record date for determining  which holders of Common Stock
shall be entitled to receive such dividend or distribution, in proportion to the
increase  in the  number of  outstanding  shares  (and  shares  of Common  Stock
issuable upon conversion of all such securities  convertible  into Common Stock)
of Common Stock as a result of such dividend or  distribution,  and the Exercise
Price shall be adjusted so that the aggregate amount payable for the purchase of
all the Warrant Shares issuable hereunder  immediately after the record date for
such  dividend  or  distribution  shall  equal the  aggregate  amount so payable
immediately before such record date.

                  (h) If the Company  declares a dividend on Common Stock (other
than a dividend  covered by subsection  (g) above) or  distributes to holders of
its Common Stock,  other than as part of its  dissolution  or liquidation or the
winding up of its  affairs,  any shares of its capital  stock,  any  evidence of
indebtedness  or any cash or other of its assets  (other  than  Common  Stock or
securities  convertible into or exchangeable for Common Stock), the Holder shall
receive notice of such event as set forth in Section 11 below.

                  (i) If the Company shall, at any time before the expiration of
this Warrant,  sell all or  substantially  all of its assets and  distribute the
proceeds thereof to the Company's stockholders,  the Holder shall, upon exercise
of this Warrant have the right to receive, in lieu of the shares of Common Stock
of the Company that the Holder  otherwise  would have been  entitled to receive,
the same kind and amount of assets as would  have been  issued,  distributed  or
paid to the Holder upon

                                       -5-

<PAGE>



any such distribution with respect to such shares of Common Stock of the Company
had the  Holder  been the  holder  of record  of such  shares  of  Common  Stock
receivable  upon  exercise  of this  Warrant on the date for  determining  those
entitled to receive any such distribution.  If any such distribution  results in
any cash  distribution  in excess of the Exercise Price provided by this Warrant
for the shares of Common Stock  receivable  upon exercise of this  Warrant,  the
Holder may, at the Holder's option, exercise this Warrant without making payment
of the Exercise Price and, in such case, the Company shall, upon distribution to
the Holder, consider the Exercise Price to have been paid in full and, in making
settlement  to the  Holder,  shall  obtain  receipt  of the  Exercise  Price  by
deducting an amount  equal to the Exercise  Price for the shares of Common Stock
receivable  upon exercise of this Warrant from the amount payable to the Holder.
Notwithstanding  the  foregoing,  in the event the  consideration  to be paid to
holders of Company  capital stock in any  transaction of the nature  referred to
above in this  Section  9(i) (an "Asset Sale  Transaction")  consists of cash or
cash equivalents and the consideration  payable per share of Common Stock of the
Company is less than the  Exercise  Price  hereunder,  then,  provided  that the
Company  shall have given the holder  hereof the notice  required by Section 10,
this Warrant  shall,  to the extent it has not been  exercised by the  effective
date of such Transaction, terminate upon the completion of such Transaction.

                  (j) The term "Common Stock" shall mean the Common Stock of the
Company  as the same  exists  at  September  __,  1997 or as such  stock  may be
constituted  from time to time,  except that for the purpose of this  Section 9,
the term  "Common  Stock"  shall  include  any stock of any class of the Company
which has no  preference  in respect of dividends  or of amounts  payable in the
event of any voluntary or involuntary liquidation,  dissolution or winding up of
the Company and which is not subject to redemption by the Company.

                  (k)  Whenever  the  number of Warrant  Shares or the  Exercise
Price shall be adjusted as  required by the  provisions  of this  Section 9, the
Company  forthwith  shall file in the custody of its  secretary  or an assistant
secretary,  at its  principal  office,  and  furnish to each  Holder  hereof,  a
certificate prepared by its Chief Financial Officer, showing the adjusted number
of  Warrant  Shares  and the  adjusted  Exercise  Price  and  setting  forth  in
reasonable detail the circumstances requiring the adjustments.

                  (l) No adjustment in the Exercise Price in accordance with the
provisions of this Section 9 need be made if such  adjustment  would amount to a
change in such  Exercise  Price of less than $.01;  provided  however,  that the
amount by which any  adjustment is not made by reason of the  provisions of this
paragraph (l) shall be carried forward and taken into account at the time of any
subsequent adjustment in the Exercise Price.

                  (m) If an  adjustment  is made  under  this  Section 9 and the
event to which the adjustment  relates does not occur,  then any  adjustments in
accordance with this Section 9 shall be readjusted to the Exercise Price and the
number of Warrant Shares which would be in effect had the earlier adjustment not
been made.

         10. Notice of Adjustment. So long as this Warrant shall be outstanding,
(a) if the Company shall  propose to pay any dividends or make any  distribution
upon the Common  Stock,  or (b) if the  Company  shall  offer  generally  to the
holders of Common Stock the right to subscribe to or

                                       -6-

<PAGE>



purchase any shares of any class of Common Stock or securities  convertible into
Common Stock or any other similar rights,  or (c) if there shall be any proposed
capital  reorganization of the Company in which the Company is not the surviving
entity,  recapitalization of the capital stock of the Company,  consolidation or
merger of the Company with or into  another  corporation,  sale,  lease or other
transfer of all or substantially  all of the property and assets of the Company,
or  voluntary  or  involuntary  dissolution,  liquidation  or  winding up of the
Company, or (d) if the Company shall give to its stockholders any notice, report
or other  communication  respecting any  significant or special action or event,
then in such event, the Company shall give to the Holder, at least ten (10) days
prior to the relevant date described below, a notice containing a description of
the  proposed  action or event and stating the date or expected  date on which a
record of the  Company's  stockholders  is to be taken for any of the  foregoing
purposes,   and  the  date  or  expected  date  on  which  any  such   dividend,
distribution,  subscription,  reclassification,  reorganization,  consolidation,
combination,   merger,  conveyance,   sale,  lease  or  transfer,   dissolution,
liquidation or winding up is to take place and the date or expected date, if any
is to be fixed,  as of which the  holders  of  Common  Stock of record  shall be
entitled  to  exchange  their  shares of Common  Stock for  securities  or other
property deliverable upon such event.

         11.  Notice.  Any notice to be given or to be served  upon any party in
connection  with the Warrant  must be in writing and will be deemed to have been
given and received upon confirmed receipt, if sent by facsimile, or two (2) days
after it has been  submitted  for delivery by Federal  Express or an  equivalent
