This Prospectus and the information  contained  herein are subject to completion
or  amendment.  These  securities  may not be  sold,  nor may  offers  to buy be
accepted,  prior to the time the prospectus is delivered in final form. Under no
circumstances shall this Preliminary  Prospectus  constitute an offer to sell or
the  solicitation  of an  offer  to buy nor  shall  there  be any  sale of these
securities in any  jurisdiction in which such offer,  solicitation or sale would
be unlawful prior to registration or qualification  under the securities laws of
any such jurisdiction.


                  Subject to Completion dated February 11, 1998

                                   PROSPECTUS

                        2,142,063 Shares of Common Stock
                          CELLEGY PHARMACEUTICALS, INC.

      This prospectus (this  "Prospectus")  covers the registration for possible
resale of shares  (the  "Shares")  of Common  Stock,  no par value (the  "Common
Stock"), of Cellegy Pharmaceuticals, Inc. ("Cellegy" or the "Company") that have
either been issued to, or that may in the future be issued to,  certain  persons
("Shareholders")  named in this  Prospectus,  including  shares of Common  Stock
issuable  upon the  exercise of certain  common  stock  purchase  warrants  (the
"Warrants")  held by certain of the  Shareholders.  (The Shares and Warrants are
referred to collectively as the "Securities.")

      The  Shareholders  have  represented  in the  agreements  relating  to the
purchase of their Shares or Warrants that they were  acquiring  such  Securities
for  investment  and  with no  present  intention  of  selling  the  Securities.
Nevertheless, in recognition of the fact that each such Shareholder wishes to be
legally  permitted to sell the Shares when the Shareholder deems it appropriate,
the  Company  has  filed  with  the  Securities  and  Exchange  Commission  (the
"Commission")  a registration  statement of which this  Prospectus  forms a part
(the "Registration  Statement") with respect to the sale of the Shares from time
to time. See "Plan of Distribution." To the Company's knowledge,  as of the date
of this Prospectus,  no Shareholder has entered into any agreement,  arrangement
or understanding with any particular  broker,  market maker or other person with
respect to sale of any of the Shares offered hereby.

      This  Prospectus  covers  462,809 shares of Common Stock that were issued,
and  1,537,191  shares of Common  Stock  that may be  issued in the  future,  to
certain  Shareholders  pursuant to an asset  purchase  transaction  completed on
December 31, 1997,  see "Selling  Shareholders."  In addition,  this  Prospectus
includes  142,063  shares of Common Stock that are issuable,  subject to certain
conditions,  upon exercise of Warrants held by certain  Shareholders.  While the
Company will receive  proceeds  from the exercise of the  Warrants,  it will not
receive  any of the  proceeds  from  the  resale  of the  Shares.  See  "Selling
Shareholders"  for information  with respect to Shares held or acquirable by the
Shareholders.

      Of the 2,142,063  Shares covered by this  Prospectus,  462,809 Shares have
been  issued as of the date of this  Prospectus,  94,063  Shares may be acquired
upon the exercise of Warrants held by one of the Shareholders, 48,000 Shares are
issuable  upon the  exercise  of  Warrants  held by two other  Shareholders  (if
certain  conditions  specified  in  such  Warrants  are  satisfied),  and  up to
approximately  1,537,191 Shares may be issued over time in the future to certain
of the Shareholders if certain  milestones and other conditions are satisfied in
the agreement  relating to issuance of such Shares.  See "Selling  Shareholders"
and "Plan of  Distribution."  If all of such  Shares were issued and all of such
Warrants were exercised,  the Shares covered by this Prospectus  would represent
approximately  18.1% (5.9% if the 1,537,191 shares are not issued and are deemed
not covered by the  Prospectus) of the Company's  currently  outstanding  Common
Stock.  The Shares are being offered on a continuous  basis pursuant to Rule 415
under the Securities Act of 1933, as amended (the "Securities Act"). The Company
will pay the  expenses of  registration  estimated at $37,000.  No  underwriting
discounts,  commissions or expenses are payable or applicable in connection with
the sale of the  Shares.  The  Common  Stock of  Cellegy is quoted on the Nasdaq
National  Market under the symbol  "CLGY." The Shares offered hereby may be sold
from  time to time at then  prevailing  market  prices,  at prices  relating  to
prevailing  market  prices or at  negotiated  prices.  On  February  6, 1998 the
closing  price of the Common Stock on the Nasdaq  National  Market was $7.44 per
share.  This Prospectus may be used by the Shareholders or by any  broker-dealer
who may  participate in sales of the Common Stock covered  hereby.  In addition,
any Shares  offered hereby which qualify for sale pursuant to Rule 144 under the
Securities  Act or any other  exemption  may be sold  under Rule 144 or an other
exemption rather than pursuant to this Prospectus.

      See  "RISK  FACTORS"  commencing  on page 5 for a  discussion  of  certain
factors that should be considered in connection with an investment in the Common
Stock offered hereby.

      THESE  SECURITIES  HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
AND  EXCHANGE  COMMISSION  OR  ANY  STATE  SECURITIES  COMMISSION  NOR  HAS  THE
SECURITIES AND EXCHANGE  COMMISSION OR ANY STATE  SECURITIES  COMMISSION  PASSED
UPON THE  ACCURACY OR ADEQUACY OF THIS  PROSPECTUS.  ANY  REPRESENTATION  TO THE
CONTRARY IS A CRIMINAL OFFENSE.

                                  RISK FACTORS

     An investment in the Shares of Common Stock offered  hereby is  speculative
in nature and  involves a high degree of risk.  In  addition to the  information
contained  in this  Prospectus,  the  following  factors  should  be  considered
carefully in  evaluating  the Company and its  business  before  purchasing  the
Shares of Common Stock offered hereby. This Prospectus contains  forward-looking
statements which involve risks and uncertainties, including, but not limited to,
statements  concerning the commencement  and completion of clinical trials,  the
commencement  of  commercial  sales of the  Company's  products,  the  timing of
planned regulatory filings,  the applicability to the Company's products of drug
and  cosmetic  laws  and  regulations,   the  Company's  intent  to  enter  into
collaborative arrangements and the planned activities of collaborative partners,
the  Company's  strategic  plans,  the scope of the Company's  patent  coverage,
anticipated   expenditures  and  the  need  for  additional  funds.  Discussions
containing  such  forward-looking  statements  may be found in the  material set
forth under "Risk  Factors" and in the reports  that the Company  files with the
Commission that are incorporated  herein by reference.  Actual events or results
may differ materially from those discussed in this Prospectus.

     Uncertainty of Clinical Trial Results. Before obtaining regulatory approval
for the commercial sale of many of its potential drug products, the Company must
demonstrate  through preclinical studies and clinical trials that the product is
safe and  efficacious  for use in the clinical  indication for which approval is
sought.  There  can be no  assurance  that  the  Company  will be  permitted  to
undertake or continue  clinical trials for any of its potential  products or, if
such trials are permitted,  that such products will be  demonstrated  to be safe
and  efficacious.  Moreover,  the  results  from  preclinical  studies and early
clinical  trials may not be  predictive  of  results  that will be  obtained  in
later-stage  clinical  trials,  such as the Phase III trials being  conducted by
Glaxo  Wellcome Inc.  ("Glaxo")  relating to GlylorinTM.  Thus,  there can be no
assurance that the Company's  present or future clinical trials will demonstrate
statistically  significant  safety and  efficacy  or will  result in approval to
market products.

     The Company's most advanced topical prescription  candidate,  Glylorin, has
been licensed by Cellegy to Glaxo and is currently near  completion of Phase III
clinical trials in the United States. There can be no assurance that the outcome
of the current Phase III clinical trial will be favorable, that further clinical
studies will not be needed for  Glylorin,  that the United  States Food and Drug
Administration  ("FDA") will approve  Glylorin for  marketing or that current or
future clinical trials of any of the Company's other product candidates, will be
successfully  completed  or lead to FDA  approval.  The  failure of  Glylorin to
produce  statistically  significant efficacy results in its current Phase III or
any future clinical testing, including toxicology studies, could have a material
adverse effect on the Company.

     The  evaluation of animal and human clinical test results  involves  making
judgments about data and other information that often are not conclusive.  Later
testing  may show those  judgments  to have been  erroneous.  For  example,  the
Company's beliefs regarding the potential  comparative  therapeutic  benefits of
its products compared to currently  marketed  products may be erroneous,  or the
FDA may not  agree  with  the  Company's  conclusions  regarding  such  matters.
Furthermore,  due to the  independent and blind nature of certain human clinical
testing,  there will be extended  periods  during the testing  process  when the
Company will have only limited, or no, access to information about the status or
results of the tests.  Other  pharmaceutical  companies have believed that their
products performed satisfactorily in early tests, only to find their performance
in later  tests,  including  Phase III  clinical  trials,  to be  inadequate  or
unsatisfactory,  or that FDA  Advisory  Committees  have  declined to  recommend
approval of the drugs, or that the FDA itself refused approval,  with the result
that such  companies'  stock  prices  have  fallen  precipitously.  The  Company
believes that an unsuccessful Glylorin Phase III clinical result could result in
a substantial reduction in the Company's stock price.

     History  of Losses;  Future  Profitability  Uncertain.  The  Company  has a
history of operating losses and expects to incur substantial additional expenses
with  resulting  quarterly  losses  over at least the next  several  years as it
continues to develop its potential products and to devote significant  resources
to preclinical studies,  clinical trials and manufacturing.  As of September 30,
1997, the Company had accumulated net losses of approximately  $17.4 million. To
date, the Company has not sought regulatory approval to distribute any products.
The time and  resource  commitment  required to achieve  market  success for any
individual  product is extensive and  uncertain.  No assurance can be given that
the Company's  product  development  efforts will be  successful,  that required
regulatory

                                       5

<PAGE>


approvals can be obtained,  that potential  products can be  manufactured  at an
acceptable cost and with appropriate  quality or that any approved  products can
be successfully marketed.

     The Company has not generated any  significant  revenues from product sales
or  royalties  from  licenses  of the  Company's  technology,  and  most  of the
potential products that may be marketed by the Company, if any, are not expected
to be marketed or approved for  marketing  for at least the next several  years.
Moreover,  the Company  anticipates that its operating expenses will continue to
increase  significantly  as the Company  increases its research and development,
preclinical, clinical, administrative and patent activities. Accordingly, in the
absence of substantial revenues from new corporate collaborations,  royalties on
product sales or other sources,  the Company  expects to incur  substantial  and
increased  operating losses in the foreseeable  future as certain of its earlier
stage potential products move into clinical development, as additional potential
products are selected as clinical  candidates  for further  development,  as the
Company invests in additional facilities or capacity, and as the Company invests
in  research  or  acquires  additional   technologies,   product  candidates  or
businesses.  The amount of net losses and the time  required to reach  sustained
profitability are highly uncertain.  To achieve sustained profitable operations,
the  Company,  alone  or with  its  collaborative  partners,  must  successfully
discover,  develop,  obtain  regulatory  approvals  for and market its potential
pharmaceutical  products.  No  assurances  can be given that the Company will be
able to achieve or sustain profitability,  and results are expected to fluctuate
from quarter to quarter.

     Early Stage of Product Development. With the exception of certain skin care
cosmeceutical  products,  Cellegy has not yet completed the  development  of its
proposed  products  or sought  regulatory  approval  for the  marketing  of drug
products   and  has  not  begun  to  market  or  generate   revenues   from  the
commercialization  of products.  Development  of most of the Company's  products
will  require  significant  additional  research  and  development.  All  of the
Company's   product   development   efforts  are  based  upon  technologies  and
therapeutic  approaches that have not been widely tested or used. Moreover,  the
Company's  beliefs  regarding the therapeutic  and commercial  potential for its
products  are based on studies  conducted  to date,  and later  studies  may not
support the Company's  current  beliefs.  In addition,  results of the Company's
studies have not been  published in medical  journals or reviewed by independent
third  parties,  and as a result have not been  subjected  to the same degree of
scrutiny  as  results  that  have  been  published  or  subjected  to  review by
independent parties.

     The  Company's  potential  products  are  subject  to the risks of  failure
inherent in the development of products based on new  technologies.  These risks
include the possibilities that the Company's therapeutic  approaches will not be
successful;  that the results from future clinical trials may not correlate with
any safety or effectiveness results from prior clinical studies conducted by the
Company or others; that some or all of the Company's potential products will not
be  successfully  developed or will not be found to be safe and effective by the
FDA, or otherwise will fail to meet applicable  regulatory  standards or receive
necessary regulatory clearances;  that the products, if safe and effective, will
be difficult to manufacture in commercial quantities at reasonable costs or will
be  uneconomical  to  market;  that  proprietary  rights of third  parties  will
preclude the Company from commercializing  such products;  or that third parties
will market  superior or  equivalent  products.  There can be no  assurance  the
Company's  research and development  activities will result in any  commercially
viable products.

     Possible FDA  Regulation of  Cosmeceutical  Products as Drugs.  The Company
intends to introduce  products  that will compete in the  cosmeceutical  market.
"Cosmeceuticals" are not defined in the federal Food, Drug and Cosmetic Act (the
"FD&C Act"). The FDA has not defined the term by regulation and may consider use
of the term to imply drug-like qualities.  Cosmeceuticals (a hybrid of the words
"cosmetics" and  "pharmaceuticals") are products that contain active ingredients
which, when applied to the skin, will enhance appearance.  Cosmeceuticals  which
satisfy the  definition of a cosmetic  under the FD&C Act and which are not also
drugs under that  statute are not subject to the same FDA  requirements  as drug
products. For example, cosmeceutical products that constitute cosmetics (but not
drugs as  well) as  defined  by  applicable  federal  laws  may be  marketed  to
consumers   without  prior  approval  by  the  FDA,  and  without   requiring  a
prescription  from a  physician.  The  Company  intends  to  develop a number of
cosmeceutical  products,  including  a  product  that  will  compete  in what is
generally referred to as the "anti-wrinkling" market.

                                       6

<PAGE>


     The FDA has at times in the past contended,  and may in the future contend,
that one or more cosmeceutical products, including the Company's or competitors'
anti-wrinkling  products  that are  currently  marketed  or may in the future be
marketed, are not cosmetics but instead are subject to regulation as drugs. Even
if the FDA were not ultimately to prevail with regard to such a contention, such
a claim by the FDA could have a material adverse effect on the Company's ability
to market its proposed  cosmeceutical  products and could significantly delay or
prohibit  marketing of such  products.  The extent to which  different  kinds of
current or future  cosmeceutical  products of the Company or its competitors are
subject to FDA regulation as drugs, and the extent to which the FDA will seek to
become more active in regulating  cosmeceutical  products, such as products that
compete in the "anti-wrinkling" market, is uncertain, but will depend in part on
the claims made for the cosmeceuticals by their manufacturers and marketers. The
inability  of the  Company  to market its  proposed  cosmeceutical  products  as
cosmetics without prior FDA approval could have a material adverse effect on the
Company's business and financial condition.

     Competition  and  Technological  Change.  The  pharmaceutical  industry  is
subject to rapid and significant  technological  change.  In the development and
marketing  of  topical  prescription  drugs,  skin care and other  cosmeceutical
products  and  drug  delivery  systems,   Cellegy  faces  intense   competition.
Competitors  of the  Company in the United  States and abroad are  numerous  and
include,  among  others,  major  pharmaceutical,  chemical,  cosmetic,  consumer
product, and biotechnology companies,  specialized firms, universities and other
research institutions.  There can be no assurance that the Company's competitors
will not succeed in developing technologies and products that are more effective
than any which are being  developed  by the  Company  or that  would  render the
Company's technology and potential products obsolete and noncompetitive. Many of
these competitors have substantially  greater financial and technical resources,
production  and  marketing  capabilities  and  regulatory  experience  than  the
Company.  In addition,  many of the  Company's  competitors  have  significantly
greater  experience  than the Company in preclinical  testing and human clinical
trials of  pharmaceutical  products  and in obtaining  FDA and other  regulatory
approvals of products for use in health care. There can be no assurance that the
Company's  products under development will be able to compete  successfully with
existing products or products under development by other companies, universities
and other  institutions  or that they will  obtain  regulatory  approval  in the
United  States  or  elsewhere.  The  Company  also  competes  with  universities
developing drug delivery technologies and with several companies which have been
formed to develop unique  delivery  systems.  In addition,  these  companies and
academic  and research  institutions  compete  with  Cellegy in  recruiting  and
retaining highly qualified scientific and management personnel.

     Patents and Proprietary Technology. The Company's success depends, in part,
on its ability to obtain patent protection for its products and methods, both in
the United States and in other countries.  Several of the Company's products are
based on existing  compounds with a history of use in humans but which are being
developed by the Company for new therapeutic  use in skin diseases  unrelated to
the systemic  diseases for which the compounds  were  previously  approved.  The
Company cannot obtain composition patent claims on the compound itself, and will
instead need to rely on patent claims,  if any,  directed to use of the compound
to treat certain conditions or to specific formulations.  The Company may not be
able to prevent a  competitor  from using that  formulation  or  compound  for a
different purpose. No assurance can be given that any additional patents will be
issued to the Company,  that the  protection of any patents issued in the future
will be  significant  or that  current or future  patents  will be held valid if
subsequently challenged.

     The  patent  position  of  companies  engaged  in  businesses  such  as the
Company's business generally is uncertain and involves complex legal and factual
questions.  There is a substantial  backlog of patent applications at the United
States Patent and Trademark Office ("USPTO").  Further, issued patents can later
be held invalid by the patent office issuing the patent or by a court. There can
be no assurance that any patent applications  relating to the Company's products
or methods  will issue as patents,  or, if issued,  that the patents will not be
challenged,  invalidated or circumvented  or that the rights granted  thereunder
will provide a  competitive  advantage to the Company.  In addition,  many other
entities  are  engaged  in  research  and  product  development  efforts in drug
delivery,  skin  biology and  cosmeceutical  fields  that may  overlap  with the
Company's currently anticipated and future products, and such other entities may
currently  have,  or may  obtain in the  future,  legally  blocking  proprietary
rights,  including  patent  rights,  in one or more  products  or methods  under
development  or  consideration  by the  Company.  These  rights may  prevent the
Company from commercializing  technology, or may require the

                                       7

<PAGE>


Company to obtain a license  from the entity to practice the  technology.  There
can be no assurance  that the Company  will be able to obtain any such  licenses
that may be required on  commercially  reasonable  terms, if at all, or that the
patents underlying any such licenses will be valid or enforceable. Moreover, the
laws of certain foreign  countries do not protect  intellectual  property rights
relating to United States  patents as  extensively as those rights are protected
in the United States.  As with other companies in the  pharmaceutical  industry,
the Company is subject to the risk that persons  located in such  countries will
engage in  development,  marketing or sales  activities  of products  that would
infringe  the  Company's  patent  rights if such  activities  were in the United
States.

     The  agreements  with the  University of  California  pursuant to which the
Company  has  exclusive  license  rights  to  certain  drug  delivery  and other
technology  contain certain  development and  performance  milestones  which the
Company must satisfy in order to retain such rights. While the Company currently
believes it will be able to satisfy  the  milestone  dates,  a loss of rights to
these technologies could have a material adverse effect on the Company.

     Dependence  on  Collaborative  Partners.  In view of the early stage of the
Company and its research and  development  programs,  the Company has restricted
hiring to research and development  scientists and a small  administrative staff
and has made limited or no investment in marketing, product sales and regulatory
compliance resources.  The Company has granted to Glaxo certain exclusive rights
to commercialize Glylorin for the indications covered by the Company's agreement
with Glaxo,  and may in the future  enter into  agreements  with  certain of its
collaborative  partners  granting similar rights with respect to other products.
The  Company  has  other  collaborative  agreements  with  certain  third  party
companies   or   academic   institutions,   and  intends  to  enter  into  other
collaborative  agreements in the future, relating to the research,  development,
manufacture  and marketing of certain  potential  products.  In some cases,  the
Company is relying,  and in the future will rely, on its collaborative  partners
to conduct clinical  trials,  to compile and analyze the data received from such
trials,  to obtain  regulatory  approvals and, if approved,  to manufacture  and
market these  products.  As a result,  the Company may have little or no control
over the development of these potential products, including Glylorin, and little
opportunity  to review  clinical data before or after public  announcement.  The
Company  believes that an  unsuccessful  Phase III clinical result with Glylorin
could result in the termination of the license agreement by Glaxo.  There can be
no assurance that the Company will be able to establish any other  collaborative
arrangements  or that they will be  successful.  Failure  to enter into any such
arrangements that in the future might be necessary could have a material adverse
effect on the Company's business and financial condition.

     Government   Regulation   and  Drug  Product   Approvals.   The   research,
development,  testing,  manufacture,   labeling,  distribution,   marketing  and
advertising of products such as the Company's  products and its ongoing research
and development  activities are subject to extensive  regulation by governmental
regulatory  authorities in the United States and other countries.  The extensive
preclinical and clinical testing requirements and regulatory approval process of
the FDA in the  United  States  and of certain  foreign  regulatory  authorities
require a number of years and the  expenditure of substantial  resources.  There
can be no  assurance  that the  Company  will be able to  obtain  the  necessary
approvals  for  clinical  testing or for the  marketing  of products on a timely
basis or at all. Moreover,  additional government regulations may be established
that could  prevent or delay  regulatory  approval  of the  Company's  products.
Delays in obtaining regulatory approvals could have a material adverse effect on
the Company's business and results of operations. Even if regulatory approval of
a product is granted,  such approval may include significant  limitations on the
indicated  uses of the product or the manner in which or conditions  under which
the product may be marketed. For example, even if the Company seeks FDA approval
of a product for non-prescription  consumer sales, the FDA could instead require
that the product be distributed by means of a  prescription  before  considering
approval for  distribution  as a  non-prescription  product.  Prescription  only
approval,  which the Company  believes is common where a company seeks  approval
for a product  involving a new  compound or a compound  previously  approved for
other uses, could delay for several years, or indefinitely, distribution through
the  non-prescription  channel of the  Company's  products  which are subject to
premarket  review and  approval  by the FDA.  Moreover,  failure to comply  with
regulatory  requirements for marketing drugs, or if the Company's  cosmeceutical
products  are  deemed  to be drugs by the FDA,  could  subject  the  Company  to
regulatory  or  judicial  enforcement  actions,  including,  but not limited to,
product recalls or seizures, injunctions against production, distribution, sales
and  marketing,  civil  penalties,  criminal  prosecution  of the  Company,  its
officers or  employees,  refusals to approve new  products and  suspensions  and
withdrawals  of existing  approvals,  as well as potentially  increased  product
liability  exposure.  Sales of the Company's  products outside the United States
will be

                                       8

<PAGE>


subject to  regulatory  requirements  governing  clinical  trials and  marketing
approval. These requirements vary widely from country to country and could delay
introduction of the Company's products in those countries.

     Limited  Experience with Clinical Trials.  The Company has conducted only a
limited  number of clinical  trials to date.  There can be no assurance that the
Company  will be able to  successfully  commence and complete all of its planned
clinical  trials without  significant  additional  resources and  expertise.  In
addition,  there can be no assurance that the Company will meet its contemplated
development  schedule for any of its  potential  products.  The inability of the
Company or its  existing  or any future  collaborative  partners  to commence or
continue clinical trials as currently  planned,  to complete the clinical trials
on a timely basis or to  demonstrate  the safety and  efficacy or its  potential
products, would have a material adverse effect on the business and the financial
condition of the Company.

     Future Capital  Needs;  Uncertainty  of Additional  Funding.  The Company's
operations to date have consumed substantial amounts of cash. The Company's cash
needs are expected to continue to increase  significantly over at least the next
several years in order to fund the additional expenses the Company will incur as
it expands its current  research and development  programs,  particularly in the
drug delivery,  prescription pharmaceutical and cosmeceutical product areas. The
Company has no current source of significant  ongoing revenues or capital beyond
existing  cash,  and  payments,  if any,  that may be  received  pursuant to the
existing licensing  agreements with Glaxo. In order to complete the research and
development  and other  activities  necessary  to  commercialize  its  products,
additional  financing may be required.  The Company's  future  expenditures  and
capital  requirements  depend on numerous factors,  including without limitation
the  progress  of  its  research  and  development  programs,  the  progress  of
preclinical  and  clinical  testing,  the time and costs  involved in  obtaining
regulatory  approvals  and  complying  with  pre- and  post-regulatory  approval
requirements,  the costs of filing,  prosecuting,  defending  and  enforcing any
patent claims and other intellectual  property rights,  competing  technological
and  market   developments,   changes  in  the   Company's   existing   research
relationships,   the   ability  of  the  Company  to   establish   collaborative
arrangements,  the development of commercialization activities and arrangements,
the  purchase of capital  equipment  and any funding  that may be received  from
third parties  pursuant to license,  development  or other  agreements  that the
Company may enter into in the future and the level of royalties or revenues,  if
any, from commercial product sales.

     As a result,  the Company may seek private or public equity investments and
future  collaborative  arrangements  with third  parties to help fund its future
cash  needs.  There is no  assurance  that such  funding  will be  available  on
acceptable  terms,  if at all.  Insufficient  funding may require the Company to
delay,  reduce  or  eliminate  some  or  all  of its  research  and  development
activities,  planned clinical trials and  administrative  programs.  The Company
believes  that  available  cash  resources  will  be  adequate  to  satisfy  its
anticipated capital needs through at least December 31, 1999.

     Limited Sales and Marketing  Experience.  The Company may market certain of
its products,  if  successfully  developed and approved,  through a direct sales
force  in  the  United  States  and  through  sales  and  marketing  partnership
arrangements or distribution arrangements outside the United States. The Company
has no history or experience in sales, marketing or distribution.  To market its
products  directly,  the  Company  must either  establish a marketing  group and
direct sales force or obtain the assistance of one or more third parties.  There
can be no  assurance  that  the  Company  will be able to  establish  sales  and
distribution  capabilities  or  succeed  in gaining  market  acceptance  for its
products.  If the Company enters into marketing or licensing  arrangements  with
established  pharmaceutical companies, the Company's revenues will be subject to
the payment provisions of such arrangements and will be dependent on the efforts
of third  parties.  There can be no  assurance  that the Company will be able to
successfully  establish  a direct  sales  force or that its  collaborators  will
effectively market any of the Company's potential products, and the inability of
the Company or its  collaborators  to do so could have a material adverse effect
on the business and financial condition of the Company.

     Manufacturing  Limitations;  Suppliers.  The Company has no  experience  in
manufacturing commercial quantities of its potential products and currently does
not have any capacity to manufacture  potential  products on a commercial  scale
itself. The Company currently relies on a third party to manufacture unprocessed
compounds into  therapeutic  products.  Although the Company believes that there
will be adequate third party  manufacturers,

                                       9

<PAGE>


there can be no assurance that the Company will be able to enter into acceptable
agreements  with  third  party  manufacturers,  and the  Company  is and will be
dependent upon third party contract manufacturers for such production. There can
be no  assurance  that the Company will  continue to be able to obtain  contract
manufacturing  on  commercially  acceptable  terms for compounds or products and
quantities currently obtainable. There can be no assurance that manufacturing or
quality  control  problems  will not  arise at the  manufacturing  plants of the
Company's  contract  manufacturers  or that such  manufacturers  will be able to
maintain  the  compliance  with the FDA's  current good  manufacturing  practice
requirements necessary to continue manufacturing the Company's products.

     Uncertainty  Related to Health Care  Industry.  The health care industry is
subject to changing  political,  economic  and  regulatory  influences  that may
significantly affect the purchasing practices and pricing of human therapeutics.
Cost  containment  measures,  whether  instituted  by health care  providers  or
enacted  as a result  of  government  health  administration  regulators  or new
regulations,   such  as  pricing  limitations  or  formulating  eligibility  for
dispensation by medical  providers,  could result in greater  selectivity in the
availability of treatments. Such selectivity could have an adverse effect on the
Company's  ability  to  sell  its  prescription  products  and  there  can be no
assurance  that adequate  third party coverage will be available for the Company
to maintain  price levels  sufficient to generate an  appropriate  return on its
investment in product development.  Third-party payors are increasingly focusing
on the cost-benefit profile of alternative  therapies and prescription drugs and
challenging  the prices charged for such products and services.  Also, the trend
towards  managed health care in the United States and the  concurrent  growth of
organizations  such as health maintenance  organizations  which could control or
significantly  influence the purchase of health care  services and products,  as
well as  legislative  proposals  to  reform  health  care or  reduce  government
insurance programs, may all result in lower prices or proposals to reform health
care or reduce  government  insurance  programs  or  result  in lower  prices or
reduced markets for the Company's  products.  The cost containment  measures and
reforms that  government  institutions  and third party  payors are  considering
instituting  could  result  in  significant  and  unpredictable  changes  to the
marketing, pricing and reimbursement practices of prescription drugs marketed by
bio-pharmaceutical  companies  such as the  Company.  The  adoption  of any such
measures or reforms  could have a material  adverse  effect on the  business and
financial condition of the Company.  However,  cosmeceutical  products generally
are not reimbursed by third party payors.

     Dependence Upon Key Employees. The success of the Company is dependent upon
the efforts of its senior  management  team,  including Dr. Carl R.  Thornfeldt,
Chairman of the Board of Directors and Medical  Director of the Company,  and K.
Michael  Forrest,  Chief  Executive  Officer  of the  Company.  A change  in the
association of these  individuals or other officers and directors of the Company
could adversely affect the Company if suitable  replacement  personnel could not
be  employed.  The  success of the  Company  also  depends  upon its  ability to
continue to attract and retain  qualified  scientific  and technical  personnel.
There  is  intense  competition  for  qualified  personnel  in the  areas of the
Company's  activities,  and there can be no  assurance  that the Company will be
able to continue to attract and retain the qualified personnel necessary for the
development or expansion of its business.

     Environmental  Regulation.  The  Company is subject to  federal,  state and
local laws and regulations governing the use, generation,  manufacture, storage,
discharge,  handling  and disposal of certain  materials  and wastes used in its
operations,  some of  which  are  classified  as  "hazardous."  There  can be no
assurance  that the Company will not be required to incur  significant  costs to
comply with  environmental  laws,  the  Occupational  Safety and Health Act, and
state, local and foreign counterparts to such laws, rules and regulations as its
activities   are  increased  or  that  the   operations,   business  and  future
profitability of the Company will not be adversely affected by current or future
laws, rules and regulations. The risk of accidental contamination or injury from
hazardous materials cannot be eliminated.  In the event of such an accident, the
Company could be held liable for any damages that result and any such  liability
could exceed the resources of the Company.  In any event,  the cost of defending
claims  arising  from such  contamination  or injury  could be  substantial.  In
addition,  the Company  cannot  predict the extent of the adverse  effect on its
business  or the  financial  and other  costs  that  might  result  from any new
government  requirements  arising out of future  legislative,  administrative or
judicial actions.

     Risk  of  Product  Liability;  Limited  Product  Liability  Insurance.  The
testing,  marketing and sale of human health care  products  entails an inherent
risk of  allegations  of  product  liability.  There  can be no  assurance  that

                                       10

<PAGE>


substantial  product  liability claims will not be asserted against the Company.
The Company has obtained  limited amounts of insurance  relating to its clinical
trials.  There can be no  assurance  that the Company  will be able to obtain or
maintain   insurance  on  acceptable  terms  for  its  clinical  and  commercial
activities  or that any  insurance  obtained  will provide  adequate  protection
against potential liabilities.

     Anti-Takeover  Provisions.  Certain provisions of the Company's Amended and
Restated  Articles  of  Incorporation,   as  well  as  the  California   General
Corporation Law, could  discourage a third party from attempting to acquire,  or
make it more  difficult  for a third  party to  acquire,  control of the Company
without approval of the Company's Board of Directors. Such provisions could also
limit the price that certain investors might be willing to pay in the future for
shares  of the  Common  Stock.  Certain  of such  provisions  allow the Board of
Directors to authorize the issuance of preferred  stock with rights  superior to
those of the Common  Stock.  The rights of the  holders of Common  Stock will be
subject to, and may be  adversely  affected by, the rights of the holders of any
preferred  stock that may be issued in the future.  The  issuance  of  preferred
stock could adversely affect the voting power of holders of Common Stock and the
likelihood  that such holders will receive  dividend  payments and payments upon
liquidation.  The  Company  has no current  plans to issue  shares of  preferred
stock.  The Company is also  subject to the  provisions  of Section  1203 of the
California  General  Corporation  Law which requires that a fairness  opinion be
provided to the Company's shareholders in connection with their consideration of
any proposed "interested party" reorganization transaction.

     Volatility  of  Stock  Price.  The  stock  market  has  from  time  to time
experienced  significant price and volume  fluctuations that may be unrelated to
the operating performance of particular companies. In addition, the market price
of  the  Common   Stock,   like  the  stock   prices  of  many   publicly-traded
pharmaceutical, chemical, consumer, and biotechnology companies, may prove to be
highly volatile.  Announcements  of technological  innovations or new commercial
products by the Company or its competitors,  developments or disputes concerning
patent or proprietary  rights,  publicity  regarding actual or potential medical
results   relating  to  products  under   development  by  the  Company  or  its
competitors,  regulatory  developments  in both the United  States  and  foreign
countries,  public concern as to the safety of pharmaceutical products, sales of
a large  number of shares of Common  Stock in the market and  economic and other
external factors, as well as period-to-period fluctuations in financial results,
among other  factors,  may have a significant  impact on the market price of the
Common Stock.

     Neptune  sold and  transferred  certain  assets to Company  pursuant to the
Neptune  Agreement  relating  primarily to a topical  product  candidate for the
treatment  for  anal  fissures  and   hemorrhoids   and  certain  other  related
intellectual  property.  CIBC  Oppenheimer  Corp.  acted as the  underwriter  in
connection with the Company's  November 1997 public offering of shares of Common
Stock.  The Trout Group LLC is an investment  relations firm and BMC, Inc., is a
media relations firm, both of which provide  services to the Company pursuant to
an agreement with the Company.

     The  Registration  Statement  of which this  Prospectus  is a part is being
filed,  and  the  Shares  offered  hereby  are  included  herein,   pursuant  to
registration rights included in the Neptune Agreement,  the Underwriter Warrant,
the Trout Warrant, and the BMC Warrant (together, the "Registration Rights"). In
recognition  of the fact that each such  Shareholder,  even  though  subject  to
certain lock-up restrictions or other conditions prohibiting exercise or sale of
underlying  Shares,  wishes to be legally  permitted  to sell the Shares when it
deems  appropriate,  the Company has filed the  Registration  Statement with the
Commission  with  respect to the sale of such Shares  from time to time.  To the
Company's  knowledge,  as of the date of this  Prospectus,  no  Shareholder  has
entered into any  agreement,  arrangement or  understanding  with any particular
broker or market maker with respect to sale of any of the Shares offered hereby.

     Under the terms of the Underwriter Warrant the Underwriter has the right to
acquire up to 94,063  shares of Common  Stock at an exercise  price of $9.75 per
share.  The  Underwriter  Warrant  is  exercisable  for a period  of four  years
commencing  November 19, 1998,  and includes  certain  registration  rights with
respect  to the Common  Stock  issuable  upon the  exercise  of the  Underwriter
Warrant. The Underwriter Warrant includes provisions restricting sale, transfer,
assignment  or  hypothecation  of  any  shares  acquired  upon  exercise  of the
Underwriter  Warrant  until  November  19,  1998,  except as to officers of CIBC
Oppenheimer Corp. The exercise price and number of shares issuable upon exercise
of  the   Underwriter   Warrant  may  be  subject  to  adjustment   pursuant  to
anti-dilution provisions.

     Under the terms of the Trout  Warrant and BMC Warrant,  each  Warrantholder
has the right to acquire up to 24,000 shares of Common Stock, with such Warrants
becoming  exercisable at the rate of 2,000 Shares each month commencing  October
1, 1997.  The exercise price varies with the actual Common Stock market price on
the dates the Warrants become exercisable.  However, the exercise prices will be
no greater  than $15 per Share or less than $8.75 per Share.  The Trout  Warrant
and BMC Warrant are exercisable for a period of five years commencing on October
1, 1997,  but  subject  to  earlier  termination  under  certain  circumstances,
including cancellation of the service agreement.

     As of the date of this  Prospectus,  462,809  shares  have  been  issued to
Neptune.  Under  the  Neptune  Agreement,  the  Company  is  obligated  to issue
additional  shares to Neptune from time to time upon the  attainment  of various
milestones,  and  subject  to  the  satisfaction  of  certain  other  conditions
specified in the Neptune  Agreement.  This Prospectus  covers  1,537,191 of such
shares. As of the date of this Prospectus,  none of these  potentially  issuable
additional  shares  have been issued and there can be no  assurance  that any of
such shares will be issued in the future.

                              PLAN OF DISTRIBUTION

     The  Registration  Statement of which this Prospectus forms a part has been
filed pursuant to the Registration Rights. To the Company's knowledge, as of the
date hereof,  no  Shareholder  has entered into any  agreement,  arrangement  or
understanding  with any  particular  broker or market  maker with respect to the
Shares  offered  hereby,  nor does the Company  know the  identity of any of the
brokers or market makers that any Shareholder may utilize in connection with the
sale of any Shares.  The Shares covered hereby may be offered and sold from time
to time by the  Shareholders.  The  Shareholders  will act  independently of the
Company in making decisions concerning sales or other disposition of any Shares,
and will act  independently  of the Company in making  decisions with respect to
the timing,  manner and size of each sale.  Such sales may be made on the Nasdaq
National  Market or  otherwise,  at prices  and on terms then  prevailing  or at
prices  related to the then market  price,  or in  negotiated  transactions.  In
addition,  any Shares offered hereby which qualify for sale pursuant to Rule 144
under the Securities  Act of 1933 or any other  exemption may be sold under Rule
144 or an other exemption rather than pursuant to this Prospectus.

     The Shares may be sold by one or more of the following methods: (a) a block
trade in which the broker-dealer engaged by the Shareholder will attempt to sell
the  shares  as agent but may  position  and  resell a  portion  of the block as
principal  to  facilitate  the  transaction;  (b) through  privately  negotiated
transactions; (c) purchases by the broker-dealer as principal and resale by such
broker or dealer for its account pursuant to this  Prospectus;  and (d) ordinary
brokerage transactions and transactions in which the broker solicits purchasers.
To the Company's  knowledge,  the Shareholders  have not, as of the date hereof,
entered into any arrangement with a broker-dealer for the sale of shares through
a block trade,  special offering,  or secondary  distribution of a purchase by a
broker-dealer.  In effecting sales,  broker-dealers  engaged by the Shareholders
may arrange for other broker-dealers to participate. Broker-dealers will receive
commissions or discounts from the Shareholders in amounts to be negotiated.

     In offering  their Shares,  the  Shareholders  and any  broker-dealers  who
execute sales for the Shareholders may be deemed to be "underwriters" within the
meaning of the  Securities  Act in connection  with such sales,  and any profits
realized by the Shareholders and the compensation of such  broker-dealer  may be
deemed to be underwriting discounts and commissions.

     The  Shareholders  have advised the Company that,  during such time as they
may be engaged in a distribution of the shares of Common Stock included  herein,
they will comply with the  applicable  provisions  under  Regulation M under the
Securities Exchange Act of 1934, as amended ("Regulation M"), and, in connection
therewith,   each  of  the   Shareholders  has  agreed  not  to  engage  in  any
stabilization  activity in connection  with any  securities  of the Company,  to
furnish copies of this Prospectus to each broker-dealer through which the shares
of Common Stock included  herein may be offered,  and not to bid for or purchase
any  securities  of the Company or attempt to induce any person to purchase  any
securities of the Company  except as permitted  under  Regulation M. Each of the
Shareholders  has also agreed to inform the Company and  broker-dealers  through
whom  sales  may be made  hereunder  when  the  distribution  of the  shares  is
completed.

     Rule 102 and 103 under Regulation M prohibit participants in a distribution
from bidding for or  purchasing  for an account in which the  participant  has a
beneficial  interest,  any  of  the  securities  that  are  the  subject  of the
distribution.  Rule 104 under  Regulation M governs bids and  purchases  made to
stabilize  the price of a security  in  connection  with a  distribution  of the
security.

     This offering will  terminate as to each  Shareholder on the earlier of (a)
the date on  which  such  Shareholder's  shares  may be  resold  without  volume
restrictions  under the  Securities  Act;  or (b) the date on which  all  Shares
offered  hereby have been sold by the  Shareholders.  There can be no  assurance
that any of the Shareholders  will sell any or all of the shares of Common Stock
offered hereby.

     Pursuant  to the  registration  rights  granted in the  Neptune  Agreement,
Neptune and the  Shareholders  identified in this  Prospectus as persons who may
receive  Shares from Neptune  have agreed to sell their Shares  (referred to for
this  purpose as  "Registrable  Securities")  pursuant to this  Prospectus  only
during a "Permitted Window."

                                       14

<PAGE>


     A "Permitted Window" is a period of 60 consecutive calendar days commencing
upon delivery to the Neptune  Shareholder of the Company's written  notification
to the Neptune Shareholder in response to a Notice of Resale that the Prospectus
contained in the  Registration  Statement is available  for resale.  In order to
cause a Permitted  Window to commence,  the Neptune  Shareholder must first give
written  notice to the Company of its present  intention  to sell part or all of
the Registrable Securities pursuant to such registration (a "Notice of Resale").
Upon receipt of such Notice of Resale,  the Company will give written  notice to
the Neptune  Shareholders as soon as practicable,  but in no event not more than
three  business  days after such  receipt,  that (A) the  Permitted  Window will
commence on the date such notice is received by the Neptune Shareholder,  (B) it
is necessary for the Company to supplement the Prospectus or make an appropriate
filing  with the  Commission  so as to cause the  Prospectus  to become  current
(unless the Company  exercises  its  deferral  rights as provided in the Neptune
Agreement), or (C) the Company is required under the Securities Act to amend the
Registration  Statement in order to cause the  Prospectus to be current  (unless
the Company exercises its deferral rights as provided in the Neptune Agreement).
If the Company  determines that a supplement to the Prospectus,  the filing of a
report  pursuant  to the  Exchange  Act  or an  amendment  to  the  Registration
Statement  is  necessary,  it will  take  such  actions  as  soon as  reasonably
practicable  (subject to certain  exceptions),  and the Company  will notify the
Neptune Shareholder of the filing of such supplement,  report or amendment, and,
in the case of an amendment, the effectiveness thereof, and the Permitted Window
will then commence.  The Company is also permitted in certain  circumstances and
upon notice to the Neptune  Shareholders to suspend a Permitted  Window after it
has opened for up to 30 days (and fewer days in certain circumstances).


                                  LEGAL MATTERS

     The validity of the issuance of the shares of Common Stock  offered  hereby
will be passed upon for the Company by Fenwick & West LLP, Two Palo Alto Square,
Suite 700, Palo Alto, California 94306.

ITEM 15. Indemnification of Directors and Officers.

     The  Registrant's  Amended  and  Restated  Articles of  Incorporation  (the
"Restated  Articles") include a provision that eliminates the personal liability
of its directors to the Registrant and its shareholders for monetary damages for
breach of the directors'  fiduciary duties to the maximum extent permitted under
California law. This limitation has no effect on a director's  liability (i) for
acts or omissions that involve intentional  misconduct or a knowing and culpable
violation  of law,  (ii) for acts or  omissions  that a director  believes to be
contrary to the best  interests of the  Registrant or its  shareholders  or that
involve  the  absence of good faith on the part of the  director,  (iii) for any
transaction from which a director derived an improper personal benefit, (iv) for
acts or omissions that show a reckless  disregard for the director's duty to the
Registrant or its shareholders in circumstances in which the director was aware,
or should have been aware,  in the  ordinary  course of  performing a director's
duties, of a risk of a serious injury to the Registrant or its shareholders, (v)
for acts or omissions that constitute an unexcused  pattern of inattention  that
amounts  to an  abdication  of the  director's  duty  to the  Registrant  or its
shareholders,  (vi) under Section 310 of the California  Corporations  Code (the
"California Code") (concerning  contracts or transactions between the Registrant
and a director) or (vii) under Section 316 of the  California  Code  (concerning
directors'  liability  for  improper  dividends,  loans  and  guarantees).   The
provision  does not extend to acts or omissions of a director in his capacity as
an officer. Further, the provision has no effect on claims arising under federal
or state securities laws and will not affect the availability of injunctions and
other equitable  remedies  available to the  Registrant's  shareholders  for any
violation of a director's fiduciary duty to the Registrant or its shareholders.

     The Restated  Articles also include an authorization  for the Registrant to
indemnify its agents (as defined in Section 317 of the California Code), through
bylaws provisions, by agreement or otherwise, to the fullest extent permitted by
law.  Pursuant to this latter  provision,  the  Registrant's  Bylaws provide for
indemnification   of  the  Registrant's   directors,   officers  and  employees.
Indemnification  may only be authorized by a majority of Registrant's  directors
or shareholders or by order of a court,  unless the agent has been successful on
the  merits.   In   addition,   the   Registrant's   policy  is  to  enter  into
indemnification  agreements  with  each of its  officers  and  directors.  These
indemnification   agreements   provide  that  directors  and  officers  will  be
indemnified  and held  harmless to the fullest  extent  permitted by law.  These
agreements,  together with the Restated  Articles,  may require the  Registrant,
among other things, to indemnify such directors,  officers and employees against
certain  liabilities  that may  arise by reason of their  status or  service  as
directors or officers (other than liabilities  resulting from willful misconduct
of a  culpable  nature),  to  advance  expenses  to them as they  are  incurred,
provided  that they  undertake to repay the amount  advanced if it is ultimately
determined  by a court that they are not  entitled  to  indemnification,  and to
obtain directors' and officers' insurance if available on reasonable terms.



<PAGE>


     Section 317 of the California Code makes provisions for the indemnification
of officers, directors and other corporate agents in terms sufficiently broad to
indemnify such persons, under certain circumstances,  for liabilities (including
reimbursement of expenses incurred) arising under the Securities Act.

     The Underwriting  Agreement referred to below sets forth certain provisions
with respect to the  indemnification  of the Registrant  and certain  directors,
officers,  and  controlling  persons  against  certain  losses and  liabilities,
including certain liabilities under the Securities Act.

     The Amended and  Restated  Registration  Rights  Agreement  dated April 10,
1992,  entered into by and among the Registrant and various  investors,  and the
Amended and Restated  Registration  Rights  Agreement  dated  February 10, 1995,
entered into by and among the Registrant and various investors provide for cross
indemnification of certain holders of Registrant's securities, and of Registrant
and its  officers  and  directors  for certain  liabilities  existing  under the
Securities Act and otherwise.

     The Registrant also maintains a director and officer liability policy.

ITEM 17. Undertakings.

     Insofar as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant  pursuant  to the  provisions  described  under  Item  15  above,  or
otherwise, the Registrant has been advised that in the opinion of the Securities
and  Exchange  Commission  such  indemnification  is  against  public  policy as
expressed in the Securities Act and is, therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling  person of the Registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the securities being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification  by it is  against  public  policy  as  expressed  in  the
Securities Act and will be governed by the final adjudication of such issue.

     The undersigned Registrant hereby undertakes:

     (1) To file,  during any period in which  offers or sales are being made, a
         post-effective amendment to this Registration Statement: (i) to include
         any  prospectus  required by Section  10(a)(3) of the Securities Act of
         1933 (the  "Securities  Act");  (ii) to reflect in the  prospectus  any

         Act, each filing of the Registrant's  annual report pursuant to Section
         13(a) or Section  15(d) of the  Exchange  Act that is  incorporated  by
         reference in this  Registration  Statement  shall be deemed to be a new

         the offering of such  securities at that time shall be deemed to be the
         initial bona fide offering thereof.

                        DURATION AND EXERCISE OF WARRANT

SECTION 2.1 DURATION OF WARRANT. Subject to the limitations specified in Section
2.2(a)(ii)  regarding a Cashless  Exercise,  the Warrantholder may exercise this
Warrant at any time and from time to time after 9:00 A.M., New York time, on the
date one year from the date of this  Warrant,  and before  5:00  P.M.,  New York
time,  on the  Expiration  Date. If this Warrant is not exercised on or prior to
the  Expiration  Date,  it shall become  void,  and all rights  hereunder  shall
thereupon cease.

SECTION 2.2  EXERCISE OF WARRANT.

         (a) The Warrantholder  may exercise this Warrant,  in whole or in part,
as follows:

                  (i) By  presentation  and  surrender  of this  Warrant  to the
Company  at its  principal  executive  offices  or at the  office  of its  stock
transfer agent, if any, with the Subscription

                                       3
<PAGE>

Form  annexed  hereto  duly  executed  and  accompanied  by  payment of the full
Exercise Price for each Warrant Share to be purchased; or

                  (ii) By  presentation  and  surrender  of this  Warrant to the
Company at its principal executive offices with a Cashless Exercise Form annexed
hereto  duly  executed  (a  "Cashless  Exercise").  In the  event of a  Cashless
Exercise, the Warrantholder shall exchange its warrant for that number of shares
of Common Stock  determined  by  multiplying  the number of Warrant  Shares by a
fraction,  the  numerator of which shall be the amount by which the then current
market  price per share of Common  Stock  exceeds the  Exercise  Price,  and the
denominator  of which shall be the then current market price per share of Common
Stock. For purposes of any computation under this Section  2.2(a)(ii),  the then
current market price per share of Common Stock at any date shall be deemed to be
the last sale price of the Common Stock on the business day prior to the date of
the Cashless Exercise or, in case no such reported sales take place on such day,
the average of the last  reported  bid and asked  prices of the Common  Stock on
such day, in either case on the principal national  securities exchange on which
the Common Stock is admitted to trading or listed,  or if not listed or admitted
to trading on any such  exchange,  the  representative  closing bid price of the
Common Stock as reported by NASDAQ,  or other similar  organization if NASDAQ is
no longer reporting such  information,  or if not so available,  the fair market
price of the Common Stock as determined by the Board of Directors.

         (b) Upon  receipt of this  Warrant,  in the case of Section  2.2(a)(i),
with the  Subscription  Form duly  executed  and  accompanied  by payment of the
aggregate  Exercise  Price for the Warrant Shares for which this Warrant is then
being  exercised,  or,  in the case of  Section  2.2(a)(ii),  with the  Cashless
Exercise Form duly executed,  the Company shall cause to be issued  certificates
for the total  number of whole  shares of Common Stock for which this Warrant is
being exercised (adjusted to reflect the effect of the anti-dilution  provisions
contained in Article III hereof,  if any, and as provided in Section 2.4 hereof)
in such denominations as are required for delivery to the Warrantholder, and the
Company shall thereupon deliver such certificates to the Warrantholder.

Notwithstanding  the  foregoing,  in lieu of issuing such shares of Common Stock
for  which  the  Warrant  is  being  exercised,  the  Company  may,  in its sole
discretion,  pay the  Warrantholder  cash (in the form of a check)  in an amount
equal to the total number of Warrant Shares being exercised by the Warrantholder
multiplied  by the then current  market price per share of Common Stock and upon
and to the extent of such payment such Warrant  shall be deemed  exercised.  For
purposes of this subsection  2.2(b),  the then current market price per share of
Common  Stock shall be the last sale price of the Common  Stock on the  business
day  prior  to the  date on  which  such  Warrant  is  exercised  (either  under
subsection  2.2(a)(i) or subsection  (a)(ii),  or in case no such reported sales
takes place on such day,  the average of the last  reported bid and asked prices
of the  Common  Stock on such day,  in  either  case on the  principal  national
securities  exchange on which the Common Stock is admitted to trading or listed,
or if not listed or admitted to trading on any such exchange, the representative
closing bid price of the Common  Stock as reported by NASDAQ,  or other  similar
organizations  if NASDAQ is no longer reporting such  information,  or if not so
available,  the fair market price of the Common Stock as determined by the Board
of Directors.

                                       4
<PAGE>

In the event that shares of Common  Stock are issued to the  Warrantholder  upon
exercise of this Warrant,  the Warrantholder shall be deemed to be the holder of
record  of  the   shares  of  Common   Stock   issuable   upon  such   exercise,
notwithstanding  that the stock  transfer  books of the  Company  shall  then be
closed or that  certificates  representing such shares of Common Stock shall not
then be actually delivered to the Warrantholder.  If at the time this Warrant is
exercised,  a  Registration  Statement  is not in effect to  register  under the
Securities  Act the Warrant Shares  issuable upon exercise of this Warrant,  the
Company may  require the  Warrantholder  to make such  representations,  and may
place such legends on certificates  representing  the Warrant Shares,  as may be
reasonably  required  in the  opinion of  counsel  to the  Company to permit the
Warrant Shares to be issued without such registration.

         (c) In case the Warrantholder  shall exercise this Warrant with respect
to less than all of the Warrant Shares that may be purchased under this Warrant,
the  Company  shall  execute a new  warrant in the form of this  Warrant for the
balance  of  such   Warrant   Shares  and  deliver   such  new  warrant  to  the
Warrantholder.

         (d) The Company shall pay any and all stock  transfer and similar taxes
which may be payable  in  respect of the issue of this  Warrant or in respect of
the issue of any Warrant Shares.

SECTION 2.3  RESERVATION OF SHARES.  The Company hereby agrees that at all times
there shall be reserved for issuance and delivery  upon exercise of this Warrant
such number of shares of Common  Stock or other  shares of capital  stock of the
Company  from time to time  issuable  upon  exercise of this  Warrant.  All such
shares shall be duly  authorized,  and when issued upon such exercise,  shall be
validly  issued,  fully  paid and  nonassessable,  free and clear of all  liens,
security  interests,  charges and other encumbrances or restrictions on sale and
free and clear of all preemptive rights (except the restrictions  imposed by the
legend appearing at the top of Page 1 of this Warrant).

SECTION 2.4  FRACTIONAL  SHARES.  The Company shall not be required to issue any
fraction of a share of its capital stock in connection with the exercise of this
Warrant,  and  in any  case  where  the  Warrantholder  would,  except  for  the
provisions  of this Section 2.4, be entitled  under the terms of this Warrant to
receive a fraction  of a share upon the  exercise of this  Warrant,  the Company
shall,  upon the exercise of this  Warrant and tender of the Exercise  Price (as
adjusted to cover the balance of the  share),  issue the larger  number of whole
shares  purchasable  upon  exercise of this  Warrant.  The Company  shall not be
required to make any cash or other  adjustment  in respect of such fraction of a
share to which the Warrantholder would otherwise be entitled.

SECTION 2.5  LISTING.  Prior to the  issuance of any shares of Common Stock upon
exercise of this Warrant, the Company shall secure the listing of such shares of
Common  Stock upon each  national  securities  exchange or  automated  quotation
system,  if any,  upon which shares of Common Stock are then listed  (subject to
official  notice of issuance upon exercise of this Warrant) and shall  maintain,
so long as any other shares of Common Stock shall so be listed,  such listing of
all shares of Common Stock from time to time  issuable upon the exercise of this
Warrant;  and the Company shall so list on each national  securities exchange or
automated quotation system, and shall maintain such listing of, any other shares
of capital  stock of the

                                       5
<PAGE>

Company  issuable upon the exercise of this Warrant if and so long as any shares
of the same  class  shall be  listed on such  national  securities  exchange  or
automated quotation system.

                                   ARTICLE III
                      ADJUSTMENT OF SHARES OF COMMON STOCK
                        PURCHASABLE AND OF EXERCISE PRICE

         The Exercise  Price and the number and kind of Warrant  Shares shall be
subject to adjustment  from time to time upon the happening of certain events as
provided in this Article III.

SECTION 3.1  MECHANICAL ADJUSTMENTS.

         (a) If at any time prior to the exercise of this  Warrant in full,  the
Company  shall (i) pay a dividend or make a  distribution  in the Common  Stock;
(ii)  subdivide,  reclassify  or  recapitalize  outstanding  Common Stock into a
greater  number  of  shares;  (iii)  combine,  reclassify  or  recapitalize  its
outstanding  Common  Stock into a smaller  number of  shares;  or (iv) issue any
shares of its capital stock by  reclassification  of its Common Stock (including
any such  reclassification  in connection  with a  consolidation  or a merger in
which the Company is the continuing  corporation),  the Exercise Price in effect
at the time of the  record  date of such  dividend,  distribution,  subdivision,
combination,  reclassification or recapitalization shall be adjusted so that the
Warrantholder  shall be  entitled to receive  the  aggregate  number and kind of
shares which,  if this Warrant had been exercised in full  immediately  prior to
such event,  he would have owned upon such exercise and been entitled to receive
by   virtue   of  such   dividend,   distribution,   subdivision,   combination,
reclassification or recapitalization.  Any adjustment required by this paragraph
3.1(a) shall be made successively immediately after the record date, in the case
of a  dividend  or  distribution,  or  the  effective  date,  in the  case  of a
subdivision,  combination,  reclassification  or  recapitalization  to allow the
purchase of such aggregate number and kind of shares.

         (b) If at any time prior to the exercise of this  Warrant in full,  the
Company shall make a distribution to all holders of the Common Stock of stock of
a subsidiary or securities  convertible into or exercisable for such stock, then
in lieu of an adjustment in the Exercise  Price or the number of Warrant  Shares
purchasable  upon the exercise of this  warrant,  each  Warrantholder,  upon the
exercise  hereof at any time  after  such  distribution,  shall be  entitled  to
receive  from the  Company,  such  subsidiary  or  both,  as the  Company  shall
determine,  the stock or other securities to which such Warrantholder would have
been entitled if such Warrantholder had exercised this Warrant immediately prior
thereto,  all subject to further adjustment as provided in this Article III, and
the Company shall reserve, for the life of the Warrant,  such securities of such
subsidiary  or other  corporation;  provided,  however,  that no  adjustment  in
respect of dividends or interest on such stock or other securities shall be made
during the term of this Warrant or upon its exercise.

         (c) Whenever the Exercise  Price  payable upon exercise of each Warrant
is adjusted  pursuant to paragraph  (a) of this Section 3.1, the Warrant  Shares
shall  simultaneously  be adjusted by  multiplying  the number of Warrant Shares
initially issuable upon exercise of each Warrant by the Exercise Price in effect
on the date of such  adjustment  and  dividing  the  product so  obtained by the
Exercise Price, as adjusted.

                                       6
<PAGE>

         (d) No adjustment in the Exercise  Price shall be required  unless such
adjustment would require an increase or decrease of at least ten cents ($.10) in
such price;  provided,  however,  that any  adjustments  which by reason of this
paragraph  (d) are not  required  to be made shall be carried  forward and taken
into account in any subsequent  adjustment.  All calculations under this Section
3.1  shall be made to the  nearest  cent or to the  nearest  one-hundredth  of a
share, as the case may be.  Notwithstanding  anything in this Section 3.1 to the
contrary, the Exercise Price shall not be reduced to less than the then existing
par value of the Common Stock as a result of any adjustment made hereunder.

         (e) In the event that at any time, as a result of any  adjustment  made
pursuant to Section 3.1(a),  the Warrantholder  thereafter shall become entitled
to receive any shares of the Company  other than Common  Stock,  thereafter  the
number of such other shares so receivable  upon exercise of any Warrant shall be
subject  to  adjustment  from  time to time in a manner  and on terms as  nearly
equivalent as  practicable  to the  provisions  with respect to the Common Stock
contained in Section 3.1(a).

SECTION 3.2 NOTICE OF  ADJUSTMENT.  Whenever the number of Warrant Shares or the
Exercise  Price is adjusted as herein  provided,  the Company  shall prepare and
deliver  forthwith to the  Warrantholder a certificate  signed by its President,
and by any Vice  President,  Treasurer or Secretary,  setting forth the adjusted
number of shares  purchasable upon the exercise of this Warrant and the Exercise
Price of such  shares  after such  adjustment,  a brief  statement  of the facts
requiring such adjustment and the computation by which adjustment was made.

SECTION 3.3 NO ADJUSTMENT  FOR  DIVIDENDS.  Except as provided in Section 3.1 of
this  Agreement,  no  adjustment  in respect of any cash  dividends  paid by the
Company  shall be made during the term of this  Warrant or upon the  exercise of
this Warrant.

SECTION 3.4 PRESERVATION OF PURCHASE RIGHTS IN CERTAIN TRANSACTIONS.  In case of
any  reclassification,  capital  reorganization  or other change of  outstanding
shares of  Common  Stock  (other  than a  subdivision  or a  combination  of the
outstanding  Common Stock and other than a change in the par value of the Common
Stock or in case of any  consolidation  or  merger of the  Company  with or into
another  corporation (other than a merger with a subsidiary in which the Company
is  the  continuing   corporation  and  said  merger  does  not  result  in  any
reclassification,  capital  reorganization or other change of outstanding shares
of Common Stock of the class issuable upon exercise of this Warrant)) or in case
of any sale,  lease,  transfer  or  conveyance  to  another  corporation  of the
property  and  assets of the  Company  as an  entirety  or  substantially  as an
entirety, the Company shall, as a condition precedent to such transaction, cause
such  successor or purchasing  corporation,  as the case may be, to execute with
the Warrantholder an agreement  granting the Warrantholder the right thereafter,
upon payment of the Exercise Price in effect  immediately  prior to such action,
to receive upon exercise of this Warrant the kind and amount of shares and other
securities  and  property  which he would  have owned or have been  entitled  to
receive after the  happening of such  reclassification,  change,  consolidation,
merger, sale or conveyance had this Warrant been exercised  immediately prior to
such action.  Such  agreement  shall provide for  adjustments in respect of such
shares of stock and other  securities  and  property,  which  shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
III. In the event that in  connection  with any such  reclassification,  capital
reorganizations,  change, consolidation,  merger, sale or conveyance,

                                       7
<PAGE>

additional  shares of Common  Stock  shall be  issued in  exchange,  conversion,
substitution  or  payment,  in whole or in part,  for,  or of, a security of the
Company other than Common Stock,  any such issue shall be treated as an issue of
Common Stock covered by the  provisions  of Article III. The  provisions of this
Section  3.4  shall  similarly  apply to  successive  reclassification,  capital
reorganization, consolidations, mergers, sales or conveyances.

SECTION 3.5 FORM OF WARRANT AFTER ADJUSTMENTS. The form of this Warrant need not
be changed  because of any  adjustments  in the Exercise  Price or the number or
kind of the Warrant Shares,  and Warrants  theretofore or thereafter  issued may
continue  to express  the same price and number and kind of shares as are stated
in this Warrant, as initially issued.

SECTION  3.6  TREATMENT  OF   WARRANTHOLDER.   Prior  to  due   presentment  for
registration  of  transfer of this  Warrant,  the Company may deem and treat the
Warrantholder  as the  absolute  owner  of  this  Warrant  (notwithstanding  any
notation of ownership or other writing hereon) for all purposes and shall not be
affected by any notice to the contrary.

                                   ARTICLE IV
              OTHER PROVISIONS RELATING TO RIGHTS OF WARRANTHOLDER

SECTION  4.1 NO  RIGHTS  AS  SHAREHOLDERS;  NOTICE  TO  WARRANTHOLDERS.  Nothing
contained  in  this  Warrant   shall  be  construed  as   conferring   upon  the
Warrantholder  or his  or its  transferees  the  right  to  vote  or to  receive
dividends or to consent to or receive  notice as a shareholder in respect of any
meeting of  shareholders  for the  election of  directors  of the Company or any
other matter, or any other rights whatsoever as shareholders of the Company. The
Company shall give notice to the Warrantholder by registered mail if at any time
prior to the expiration or excise in full of the Warrants,  any of the following
events shall occur:

         (a) the Company shall authorize the payment of any dividend upon shares
of Common  Stock  payable  in any  securities  or  authorize  the  making of any
distribution  (other than a cash dividend subject to the parenthetical set forth
in Section 3.1(c)) to all holders of Common Stock;

         (b) the Company  shall  authorize the issuance to all holders of Common
Stock of any additional shares of Common Stock or Common Stock Equivalents or of
rights,  options or warrants to subscribe for or purchase Common Stock or Common
Stock Equivalents or of any other subscription rights, options or warrants;

         (c) a dissolution, liquidation or winding up of the Company (other than
in  connection  with a  consolidation,  merger,  or  sale or  conveyance  of the
property of the Company as an entirety or substantially as an entirety); or

         (d) a capital  reorganization or  reclassification  of the Common Stock
(other than a subdivision  or combination  of the  outstanding  Common Stock and
other than a change in the par value of the Common  Stock) or any  consolidation
or  merger  of the  Company  with  or into  another  corporation  (other  than a
consolidation  or merger in which the Company is the continuing  corporation and
that  does  not  result  in any  reclassification  or  change  of  Common  Stock
outstanding) or in the case of any sale or conveyance to another  corporation of
the property of the Company as an entirety or substantially as an entirety.

                                       8
<PAGE>

         Such giving of notice shall be initiated  (i) at least 10 Business Days
prior  to the  date  fixed as a  record  date or  effective  date or the date of
closing of the  Company's  stock  transfer  books for the  determination  of the
shareholders entitled to such dividend,  distribution or subscription rights, or
for the  determination  of the  shareholders  entitled to vote on such  proposed
merger, consolidation, sale, conveyance, dissolution, liquidation or winding up.
Such  notice  shall  specify  such  record date or the date of closing the stock
transfer  books,  as the case may be.  Failure to provide  such notice shall not
affect  the  validity  of any action  taken in  connection  with such  dividend,
distribution or subscription  rights, or proposed merger,  consolidation,  sale,
conveyance, dissolution, liquidation or winding up.

SECTION 4.2 LOST, STOLEN,  MUTILATED OR DESTROYED  WARRANTS.  If this Warrant is
lost,  stolen,  mutilated  or  destroyed,  the Company  may, on such terms as to
indemnity or otherwise as it may in its discretion  impose (which shall,  in the
case of a mutilated Warrant, include the surrender thereof), issue a new Warrant
of like denomination and tenor as and in substitution for this Warrant.

                                    ARTICLE V
             SPLIT-UP, COMBINATION EXCHANGE AND TRANSFER OF WARRANTS

SECTION 5.1 SPLIT-UP, COMBINATION, EXCHANGE AND TRANSFER OF WARRANTS. Subject to
the provisions of Section 5.2 hereof,  this Warrant may be split up, combined or
exchanged for another Warrant or Warrants  containing the same terms to purchase
a like aggregate number of Warrant Shares. If the Warrantholder desires to split
up,  combine or exchange  Warrants,  he or it shall make such request in writing
delivered  to the Company and shall  surrender to the Company any Warrants to be
so split up,  combined or  exchanged.  Upon any such  surrender  for a split up,
combination  or exchange,  the Company  shall  execute and deliver to the person
entitled thereto a Warrant or Warrants, as the case may be, as so requested. The
Company  shall not be required to effect any split up,  combination  or exchange
which will result in the issuance of a Warrant  entitling the  Warrantholder  to
purchase  upon  exercise a fraction of a share of Common  Stock or a  fractional
Warrant.  The Company may require such  Warrantholder to pay a sum sufficient to
cover any tax or governmental  charge that may be imposed in connection with any
split up, combination or exchange of Warrants.

SECTION 5.2  RESTRICTIONS  ON  TRANSFER.  Neither  this  Warrant nor the Warrant
Shares may be disposed of or encumbered (any such action, a "Transfer"),  except
(i) to CIBC Oppenheimer Corp., any successor to the business of such company, or
any officer of such company,  or (ii) to any  underwriter  in connection  with a
Public  Offering of the Common Stock  provided (as to (ii)) that this Warrant is
exercised  upon such  Transfer  and any shares of Common  Stock issued upon such
exercise are sold by such underwriter as part of such Public Offering and, as to
both (i) and (ii),  only in accordance with and subject to the provisions of the
Securities Act and the rules and regulations promulgated  thereunder.  If at the
time of a Transfer,  a Registration  Statement is not in effect to register this
Warrant or the Warrant Shares, the Company may require the Warrantholder to make
such  representations,  and may place such legends on certificates  representing
this  Warrant,  as may be  reasonable  required in the opinion of counsel to the
Company to permit a Transfer without such registration.

                                   ARTICLE VI
                  REGISTRATION UNDER THE SECURITIES ACT OF 1933

SECTION 6.1  PIGGYBACK REGISTRATION

         (a) Right to  Include  Registrable  Securities.  If at any time or from
time to time after the date of this  Warrant and prior to the  Expiration  Date,
the Company  proposes to register any of its securities under the Securities Act
on any form for the  registration of securities  under such Act,  whether or not
for its own account (other than by a registration statement on Form S-8 or other
form which  does not  include  substantially  the same  information  as would be
required  in a form  for the  general  registration  of  securities  or would be
available for the Registrable Securities) (a "Piggyback Registration"), it shall
as expeditiously as possible give written notice to all Holders of its intention
to do so and of such  Holders'  rights under this  Section 6.1.  Such rights are
referred to  hereinafter  as "Piggyback  Registration  Rights." Upon the written
request of any such Holder made within 20 days after  receipt of any such notice
(which request shall specify the Registrable  Securities intended to be disposed
of by such Holder), the Company shall include in the Registration  Statement the
Registrable  Securities  which the Company has been so  requested to register by
the Holders  thereof and the Company shall keep such  registration  statement in
effect and maintain compliance with each Federal and state law or regulation for
the  period  necessary  for such  Holder to effect  the  proposed  sale or other
disposition (but in no event for a period greater than 120 days).

         (b) Withdrawal of Piggyback  Registration  by Company.  If, at any time
after giving  written  notice of its  intention to register any  securities in a
Piggyback   Registration  but  prior  to  the  effective  date  of  the  related
Registration  Statement,  the  Company  shall  determine  for any  reason not to
register  such  securities,  the  Company  shall  give  written  notice  of such
determination to each Holder and, thereupon, shall be relieved of its obligation
to  register  any  Registrable  Securities  in  connection  with such  Piggyback
Registration.  All best efforts  obligations of the Company  pursuant to Section
6.4 shall cease if the Company  determines to terminate  prior to such effective
date any registration where Registrable Securities are being registered pursuant
to this Section 6.1.

         (c) Piggyback  Registration  of  Underwritten  Public  Offerings.  If a
Piggyback  Registration involves an offering by or through  underwriters,  then,
(i) all Holders requesting to have their Registrable  Securities included in the
Company's  Registration  Statement must sell their Registrable Securities to the
underwriters  selected by the Company on the same terms and  conditions as apply
to other selling  shareholders and (ii) any Holder requesting to have his or its
Registrable  Securities  included in such  Registration  Statement  may elect in
writing,  not later than three Business Days prior to the  effectiveness  of the
Registration  Statement filed in connection with such registration,  not to have
his  or  its  Registrable   Securities  so  included  in  connection  with  such
registration.

         (d) Payment of Registration  Expenses for Piggyback  Registration.  The
Company shall pay all Registration Expenses in connection with each registration
of Registrable  Securities requested pursuant to a Piggyback  Registration Right
contained in this Section 6.1.

         (e) Priority in  Piggyback  Registration.  If a Piggyback  Registration
involves  an  offering  by or through  underwriters,  the  Company  shall not be
required  to  include  Registrable

                                       10
<PAGE>

Shares  therein if and to the  extent  the  underwriter  managing  the  offering
reasonably  believes in good faith and advises  each Holder  requesting  to have
Registrable  Securities  included in the Company's  Registration  Statement that
such inclusion would materially  adversely  affect such offering;  provided that
(i) if other selling  shareholders  who are  employees,  officers,  directors or
other affiliates of the Company have requested registration of securities in the
proposed  offering,  the Company  will reduce or  eliminate  such other  selling
shareholders'  securities  before any reduction or  elimination  of  Registrable
Securities;  (ii) any such reduction of  elimination  (after taking into account
the  effect  of  clause  (i)  shall  be pro  rata to all  other  holders  of the
securities of the Company exercising "piggyback  registration rights" similar to
those set forth herein in  proportion  to the  respective  number of shares they
have requested to be registered, and (iii) in such event, such Holders may delay
any offering by them of all Registrable Shares requested to be included (or that
portion of such Registrable  Shares eliminated for such period, not to exceed 60
days, as the managing underwriter shall request) and the Company shall file such
supplements and  post-effective  amendments and take such other action necessary
under  Federal and state law or  regulation  as may be  necessary to permit such
Holders to make their  proposed  offering for a period of 90 days following such
period of delay.

SECTION 6.2  DEMAND REGISTRATION

         (a) Request for Registration. If, at any time subsequent to the date of
this Warrant and prior to the Expiration  Date, any 25% Holders request that the
Company file a registration  statement  under the Securities Act, the Company as
soon as practicable shall use its best efforts to file a registration  statement
with respect to all Warrant  Shares that it has been so requested to include and
to obtain the  effectiveness  thereof,  and to take all other  action  necessary
under any Federal or state law or regulation  to permit the Warrant  Shares that
are then held  and/or  that may be acquired  upon the  exercise of the  Warrants
specified  in the  notices  of the  Holders  or  holders  thereof  to be sold or
otherwise  disposed of, and the Company shall maintain such compliance with each
such  Federal and state law and  regulation  for the period  necessary  for such
Holders or holders to effect the proposed sale or other  disposition  (but in no
event for more than 120 days); provided,  however, the Company shall be entitled
to defer  such  registration  for a period of up to 60 days if and to the extent
that its  Board of  Directors  shall  determine  that  such  registration  would
interfere with a pending corporate transaction.  The Company shall also promptly
give written notice to the Holder and the holders of any other  Warrants  and/or
the  holders  of any  Warrant  Shares who or that have not made a request to the
Company  pursuant to the  provisions of this  subsection (a) of its intention to
effect any required registration or qualification and shall use its best efforts
to effect as expeditiously as possible such registration or qualification of all
other such  Warrant  Shares that are then held and/or that may be acquired  upon
the exercise of the Warrants, the Holder or holders of which have requested such
registration or  qualification,  within 15 days after such notice has been given
by the Company,  as provided in the  preceding  sentence.  The Company  shall be
required to effect a registration or  qualification  pursuant to this subsection
(a) on one occasion only.

         (b)  Payment of  Registration  Expenses  for Demand  Registration.  The
Company  shall pay all  Registration  Expenses  in  connection  with the  Demand
Registration.

         (c) Selection of Underwriters.  If any Demand Registration is requested
to be in the form of an underwritten offering, the managing underwriter shall be
CIBC  Oppenheimer  Corp.

                                       11
<PAGE>

and the co-manager (if any) and the independent  pricer required under the rules
of the NASD (if any) shall be selected and obtained by the Holders of a majority
of the Warrant Shares to be registered.  Such selection  shall be subject to the
Company's consent,  which consent shall not be unreasonably  withheld.  All fees
and expenses (other than Registration Expenses otherwise required to be paid) of
any managing underwriter, any co-manager or any independent underwriter or other
independent  pricer  required  under the rules of the NASD  shall be paid for by
such  underwriters  or  by  the  Holders  or  holders  whose  shares  are  being
registered.  If CIBC  Oppenheimer  Corp.  should  decline  to serve as  managing
underwriter,  the Holders of a majority of the Warrant  Shares to be  registered
may select and obtain one or more managing underwriters. Such selection shall be
subject  to the  Company's  consent,  which  consent  shall not be  unreasonably
withheld.

SECTION  6.3  BUY-OUTS  OF  REGISTRATION  DEMAND.  In lieu of  carrying  out its
obligations to effect a Piggyback  Registration  or Demand  Registration  of any
Registrable  Securities  pursuant to this  Article VI, the Company may carry out
such  obligation  by  offering  to  purchase  and  purchasing  such  Registrable
Securities  requested  to be  registered  at an  amount  in  cash  equal  to the
difference  between  (a) the last sale price of the Common  Stock on the day the
request for  registration  is made and (b) the Exercise  Price in effect on such
day.

SECTION 6.4 REGISTRATION PROCEDURES.  If and whenever the Company is required to
use its best  efforts to take  action  pursuant  to any  Federal or state law or
regulation to permit the sale or other  disposition  of any Warrant  Shares that
are then held or that may be acquired upon exercise of the Warrants, in order to
effect  or cause  the  registration  of any  Registrable  Securities  under  the
Securities  Act  as  provided  in  this  Article  VI,  the  Company  shall,   as
expeditiously as practicable:

         (a) furnish to each selling  Holder of  Registrable  Securities and the
underwriters,  if any,  without  charge,  as  many  copies  of the  Registration
Statement,  the  Prospectus  or the  Prospectuses  (including  each  preliminary
prospectus)  and any  amendment  or  supplement  thereto as they may  reasonably
request;

         (b) enter into such agreements  (including an  underwriting  agreement)
and take all such other actions reasonably  required in connection  therewith in
order to expedite or facilitate the disposition of such  Registrable  Securities
and  in  such  connection,   if  the  registration  is  in  connection  with  an
underwritten  offering  (i) make  such  representations  and  warranties  to the
underwriters  in such  form,  substance  and  scope as are  customarily  made by
issuers to underwriters  in  underwritten  offerings and confirm the same if and
when  requested;  (ii)  obtain  opinions  of counsel to the  Company and updates
thereof  (which  counsel and  opinions  in form,  scope and  substance  shall be
reasonably  satisfactory to the underwriters)  addressed to the underwriters and
the Holders covering the matters  customarily  covered in opinions  requested in
underwritten  offerings and such other matters as may be reasonably requested by
such underwriters;  (iii) obtain "cold comfort" letters and updates thereof from
the Company's  accountants  addressed to the underwriters  such letters to be in
customary  form and to cover  matters of the type  customarily  covered in "cold
comfort" letters to underwriters and the Holders in connection with underwritten
offerings;  (iv) set forth in full, in any underwriting  agreement entered into,
the indemnification provisions and procedures of Section 6.5 hereof with respect
to all parties to be indemnified  pursuant to said Section; and (v) deliver such
documents and

                                       12
<PAGE>

certificates  as may be  reasonably  requested by the  underwriters  to evidence
compliance with clause (i) above and with any customary  conditions contained in
the underwriting  agreement or other agreement entered into by the Company;  the
above shall be done at each closing under such underwriting or similar agreement
or as and to the extent required thereunder;

         (c) make available for inspection by one or more representatives of the
Holders of Registrable  Securities being sold, any underwriter  participating in
any disposition  pursuant to such  registration,  and any attorney or accountant
retained  by such  Holders or  underwriter,  all  financial  and other  records,
pertinent  corporate  documents  and  properties  of the company,  and cause the
company's officers, directors and employees to supply all information reasonably
requested by any such representatives in connection with such;

         (d)  otherwise  use its best  efforts  to  comply  with all  applicable
Federal and state  regulations;  and take such other action as may be reasonably
necessary or advisable to enable each such Holder and each such  underwriter  to
consummate the sale or  disposition in such  jurisdiction  or  jurisdiction,  in
which any such Holder or underwriter  shall have requested that the  Registrable
Securities be sold.

         Except as otherwise provided in this Agreement,  the Company shall have
sole control in connection with the preparation,  filing, withdrawal,  amendment
or supplementing of each Registration Statement,  the selection of underwriters,
and the distribution of any preliminary  prospectus included in the Registration
Statement,  and may include  within the coverage  thereof  additional  shares of
Common Stock or other  securities  for its own account or for the account of one
or more of its other security holders;

         Each seller of Registrable  Securities as to which any  registration is
being  effected  shall  furnish to the Company such  information  regarding  the
distribution of such  securities and such other  information as may otherwise be
required by the Securities Act to be included in such Registration Statement.

SECTION 6.5  INDEMNIFICATION.

         (a)  Indemnification  by Company.  In connection with each Registration
Statement relating to disposition of Registrable  Securities,  the Company shall
indemnify  and hold  harmless each Holder and each  underwriter  of  Registrable
Securities  and each Person,  if any, who  controls  such Holder or  underwriter
(within  the  meaning of Section 15 of the  Securities  Act or Section 20 of the
Exchange Act) against any and all losses, claims, damages and liabilities, joint
or several  (including  any reasonable  investigation,  legal and other expenses
incurred in  connection  with,  and any amount paid in settlement of any action,
suit or proceeding or any claim  asserted),  to which they, or any of them,  may
become  subject under the  Securities  Act, the Exchange Act or other Federal or
state law or  regulation,  at common law or  otherwise,  insofar as such losses,
claims,  damages  or  liabilities  arise  out of or are  based  upon any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in any
Registration  Statement,  Prospectus or preliminary  prospectus or any amendment
thereof or supplement thereto, or arise out of or are based upon any omission or
alleged  omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading;  provided,  however,
that such indemnity  shall not inure to the benefit of any Holder or underwriter
(or any Person  controlling

                                       13
<PAGE>

such Holder or  underwriter  within the meaning of Section 15 of the  Securities
Act or Section 20 of the Exchange Act) on account of any losses, claims, damages
or liabilities  arising from the sale of  Registrable  Securities if such untrue
statement or omission or alleged  untrue  statement or omission was made in such
Registration Statement,  Prospectus or preliminary prospectus, or such amendment
or supplement,  in reliance upon and in conformity with information furnished in
writing  to the  company  by the  Holder  or  underwriter  specifically  for use
therein.  The Company shall also indemnify selling brokers,  dealer managers and
similar  securities  industry  professionals  participating in the distribution,
their  officers  and  directors  and  each  Person  who  industry  professionals
participating in the distribution,  their officers and directors and each Person
who controls  such Persons  (within the meaning of Section 15 of the  Securities
Act or Section 20 of the Exchange Act) to the same extent as provided above with
respect to the  Indemnification  of the Holders of  Registrable  Securities,  if
requested.  This indemnity agreement shall be in addition to any liability which
the Company may otherwise have.

         (b)  Indemnification  by Holder.  In connection with each  Registration
Statement,   each   Holder   shall   indemnify,   to  the  same  extent  as  the
indemnification  provided by the Company in Section  6.5(a),  the  Company,  its
directors and each officer who signs the Registration  Statement and each Person
who controls the Company (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange  Act) but only  insofar as such  losses,  claims,
damages and liabilities  arise out of or are based upon any untrue  statement or
omission  or  alleged  untrue  statement  or  omission  which  was  made  in the
Registration  Statement,   the  Prospectus  or  preliminary  prospectus  or  any
amendment thereof or supplement thereto, in reliance upon and in conformity with
information  furnished in writing by such Holder to the Company specifically for
use  therein.  In no  event  shall  the  liability  of  any  selling  Holder  of
Registrable  Securities hereunder be greater in amount than the dollar amount of
the net  proceeds  received  by such  Holder  upon the  sale of the  Registrable
Securities giving rise to such indemnification  obligation. The Company shall be
entitled to receive  indemnities  from  underwriters,  selling  brokers,  dealer
managers and similar  securities  industry  professionals  participating  in the
distribution,  to the same extent as provided above, with respect to information
so  furnished  in writing by such  Persons  specifically  for  inclusion  in any
Prospectus,  Registration  Statement or preliminary  prospectus or any amendment
thereof or supplement thereto.

         (c) Conduct of  Indemnification  Procedure.  Any party that proposes to
assert the right to be  indemnified  hereunder  will,  promptly after receipt of
notice of commencement of any action,  suit or proceeding  against such party in
respect of which a claim is to be made against an indemnifying  party or parties
under this Section,  notify each such indemnifying  party of the commencement of
such  action,  suit or  proceeding,  enclosing a copy of all papers  served.  No
indemnification  provided for in Section  6.5(a) or 6.5(b) shall be available to
any party who shall fail to give notice as provided  in this  Section  6.5(c) if
the party to whom  notice was not given was unaware of the  proceeding  to which
such notice  would have related and was  prejudiced  by the failure to give such
notice,  but the  omission  so to  notify  such  indemnifying  party of any such
action,  suit or proceeding  shall not relieve it from any liability that it may
have to any  indemnified  party for  contribution  or otherwise  than under this
Section.  In case any such action,  suit or proceeding  shall be brought against
any  indemnified  party  and it  shall  notify  the  indemnifying  party  of the
commencement  thereof,  the indemnifying  party shall be entitled to participate
in, and, to the extent that it shall wish,  jointly with any other  indemnifying
party  similarly  notified,   to  assume  the  defense  thereof,   with  counsel
satisfactory to such  indemnified

                                       14

party, and after notice from the indemnifying party to such indemnified party of
its  election  so to  assume  the  defense  thereof  and  the  approval  by  the
indemnifying  party to such  indemnified  party of its election so to assume the
defense thereof and the approval by the indemnified  party of such counsel,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other expenses,  except as provided below and except for the reasonable costs
of investigation  subsequently  incurred by such indemnified party in connection
with the defense thereof.  The indemnified  party shall have the right to employ
its counsel in any such action,  but the fees and expenses of such counsel shall
be at the expense of such indemnified party unless (i) the employment of counsel
by such  indemnified  party has been  authorized in writing by the  indemnifying
parties,  (ii) the indemnified party shall have reasonably  concluded that there
may  be a  conflict  of  interest  between  the  indemnifying  parties  and  the
indemnified  party in the  conduct of the  defense of such action (in which case
the indemnifying  parties shall not have the right to direct the defense of such
action on behalf of the  indemnified  party) or (iii) the  indemnifying  parties
shall not have  employed  counsel to assume the defense of such action  within a
reasonable time after notice of the commencement thereof, in each of which cases
the fees and  expenses of counsel  shall be at the  expense of the  indemnifying
parties.  An  indemnifying  party shall not be liable for any  settlement of any
action, suit, proceeding or claim effected without its written consent.

         (d)  Contribution.  In  connection  with  each  Registration  Statement
relating to the disposition of Registrable  Securities,  if the  indemnification
provided for in subsection (a) hereof is  unavailable  to an  indemnified  party
thereunder in respect of any losses,  claims, damages or liabilities referred to
therein, then the Company shall, in lieu of indemnifying such indemnified party,
contribute to the amount paid or payable by such  indemnified  party as a result
of such losses, claims, damages or liabilities.  The amount to be contributed by
the  Company  hereunder  shall be an amount  which is in the same  proportionate
relationship to the total amount of such losses,  claims, damages or liabilities
as the total net proceeds from the offering (before  deducting  expenses) of the
Registrable  Securities  bears  to the  total  price  to the  public  (including
underwriters'  discounts) for the offering of the Registrable Securities covered
by such registration.

         (e) Specific  Performance.  The Company and the Holder acknowledge that
remedies at law for the  enforcement  of this Section 6.5 may be inadequate  and
intend that this Section 6.5 shall be specifically enforceable.

                                   ARTICLE VII

majority of the outstanding  Registrable  Securities.  Holders shall be bound by
any consent authorized by this Section whether or not certificates  representing
such Registrable Securities have been marked to indicate such consent.

any such  provisions  in every  other  respect and of the  remaining  provisions

expenses and any other available remedy.

SECTION 7.6 COMPUTATIONS OF CONSENT. Whenever the consent or approval of Holders
of a specified  percentage  of  Registrable  Securities  is required  hereunder,
Registrable  Securities  held by the Company or its  affiliates  (other than the
Warrantholder  or  subsequent  Holders is they are deemed to be such  affiliates
solely by reason of their holdings of such Registrable  Securities) shall not be
counted in determinant whether such consent or approval was given by the Holders
of such required percentage.

SECTION 7.7 NOTICE. Any notices or certificates by the Company to the Holder and
by the  Holder  to the  Company  shall be deemed  delivered  if in  writing  and
delivered in person or by  registered  mail (return  receipt  requested)  to the
Holder  addressed to him in care of CIBC  Oppenheimer  Corp.,  CIBC  Oppenheimer
Tower,  World Financial  Center,  New York, New York 10281 or, if the Holder has

Cellegy Pharmaceuticals, Inc.

Suite 418
Foster City, CA  94404

Gentlemen/Ladies:

     At your request,  we have examined the  Registration  Statement on Form S-3
(the  "Registration  Statement")  to be filed by you  with  the  Securities  and
Exchange  Commission  (the  "Commission")  on or  about  February  11,  1998  in
connection with the  registration  under the Securities Act of 1933, as amended,
for  resale of an  aggregate  of  2,142,063  shares of your  Common  Stock  (the
"Stock"),  all of which will be sold by the  selling  shareholders  named in the
Prospectus   included   within  the   Registration   Statement   (the   "Selling
Shareholders"),   including   462,809  shares  that  are  presently  issued  and
outstanding (the "Outstanding  Shares"),  1,537,191 shares that may be issued in
the future to certain of the  Selling  Shareholders  (the  "Contingent  Shares")
pursuant to the Asset Purchase  Agreement  dated as of December 31, 1997 between
Neptune Pharmaceutical Corporation and you (the "Neptune Agreement") and 142,063
shares (the  "Warrant  Shares")  that are issuable  upon the exercise of certain
warrants  (the  "Warrants")  held by certain of the  Selling  Shareholders.  The
Outstanding  Shares,  Contingent  Shares and Warrant  Shares will be referred to
collectively herein as the "Shares."

     In rendering this opinion, we have examined the following:

     (1)     the  Registration  Statement  (including  the  Prospectus  included
             therein), together with the Exhibits filed as a part thereof;

     (2)     the articles of  incorporation  of the Company,  as amended through
             the date hereof, certified by the Company's Secretary;

     (3)     the bylaws of the  Company,  as amended  through  the date  hereof,
             certified by the Company's Secretary;

     (4)     common stock  purchase  warrant dated November 24, 1997 between the
             Company and CIBC Oppenheimer Corp.;

     (5)     common stock  purchase  warrant  dated  October 1, 1997 between the
             Company and BMC, Inc.;

     (6)     common stock  purchase  warrant  dated  October 1, 1997 between the
             Company and The Trout Group LLC;

     (7)     the Neptune Agreement;

     (8)     your  registration  statement on Form 8-A filed with the Commission
             in connection with the Company's  initial public offering in August
             1995;

     (9)     the minutes of meetings and actions by written consent of the Board
             of Directors  that are  contained in your minute books and that are
             in our  possession,  that relate to  issuance  of the  Shares,  the
             Warrants and the Warrant Shares; and

     (10)    a Management Certificate (the "Management  Certificate")  addressed
             to us and  dated of even  date  herewith  executed  by the  Company
             containing  certain factual and other  representations,  including,
             without   limitation,   information   concerning   the   number  of
             outstanding  shares of  Common  Stock  and  shares of common  stock
             issuable upon exercise of outstanding options, warrants and similar
             rights.

     In our  examination  of  documents  for purposes of this  opinion,  we have
assumed,  and express no opinion as to, the  genuineness  of all  signatures  on
original  documents,  the  authenticity  of  all  documents  submitted  to us as
originals,  the  conformity  to  originals of all  documents  submitted to us as
copies,  the legal capacity of all natural persons  executing the same, the lack
of any  undisclosed  terminations,  modifications,  waivers or amendments to any
documents  reviewed by us and the due  execution  and delivery of all  documents
where due execution and delivery are prerequisites to the effectiveness thereof.

     As to matters of fact relevant to this opinion,  we have relied solely upon
our examination of the documents  referred to above and have assumed the current
accuracy and  completeness of the information  obtained from records included in
the documents  referred to above. We have made no independent  investigation  or
other attempt to verify the accuracy of any of such  information or to determine
the existence or non-existence of any other factual matters; however, we are not
aware of any facts  that would lead us to  believe  that the  opinion  expressed
herein is not accurate.

     In  rendering  any  opinion  that the Shares  are,  or will when issued be,
"fully  paid,"  we have  assumed  that  such  shares  were or will be  issued in
accordance with the terms of the Warrants or the Neptune Agreement, and that the
Company has received (with respect to outstanding  Shares) or will receive (with
respect to Shares that may be issued in the future) full  consideration  for the
issuance of such Shares  provided for in the  Warrants or the Neptune  Agreement
(as  the  case  may  be),  and  we  have  relied  solely,   without  independent
investigation,  upon the  representation  of the  Company to that  effect in the
Management Certificate referred to above.

     Based upon the foregoing,  it is our opinion that the Outstanding Shares to
be sold by the Selling Shareholders pursuant to the Registration  Statement are,
and the Contingent Shares when and if issued pursuant to the Neptune  Agreement,
and the  Warrant  Shares when and if issued upon  exercise of the  Warrants  and
fully paid for as provided in the  Warrants  will be (assuming no change in such
documents or  applicable  law),  legally  issued and  nonassessable  and, to our
knowledge, fully paid.

     We  consent to the use of this  opinion  as an exhibit to the  Registration
Statement  and  further  consent  to  all  references  to  us,  if  any,  in the
Registration  Statement,  the  Prospectus  constituting  a part  thereof and any
amendments thereto.

     This opinion speaks only as of its date and is intended solely for your use
as an exhibit to the Registration Statement for the purpose of the above sale of
the Stock and is not to be relied upon for any other purpose.

                                                       Very truly yours,

                                                       FENWICK & WEST LLP

                                                            ------------------




                                                                    EXHIBIT 23.1


               CONSENT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

     We consent to the reference to our firm under the caption  "Experts" in the
Registration   Statement  on  Form  S-3  and  related   Prospectus   of  Cellegy
