     This Registration Statement on Form S-3 includes forward-looking statements
that  involve  substantial  risks  and  uncertainties.   These   forward-looking
statements  are  not  historical   facts,   but  rather  are  based  on  current
expectations,  estimates,  and projections about our industry,  our beliefs, and
our assumptions.  Words such as "believes,"  "anticipates," "expects," "intends"
and similar expressions are intended to identify forward-looking statements, but
are  not  the   exclusive   means  of   identifying   such   statements.   These
forward-looking  statements are not guarantees of future performance and concern
matters that involve risks and uncertainties that could cause our actual results
to differ materially from those in the forward-looking  statements.  These risks
and  uncertainties  include those  described in "Risk  Factors" and elsewhere in
this prospectus. Except as required by law, we undertake no obligation to revise
any forward-looking  statements in order to reflect events or circumstances that
may arise after the date of this prospectus. Actual events or results may differ
materially from those discussed in this prospectus.

                                   THE COMPANY

     General. We are a development-stage  specialty  bio-pharmaceutical  company
engaged in the development of prescription drugs and skin care products based on
our patented topical and transdermal drug delivery technologies.

     Cellegy's most advanced prescription product candidates include Anogesic(R)
(nitroglycerin   ointment),  a  product  for  treatment  of  anal  fissures  and
hemorrhoids,  Tostrex(TM)  (testosterone  gel),  a  transdermal  product for the
treatment of male hypogonadism,  and Tostrelle(TM) (testosterone gel), a product
for treatment of female sexual  dysfunction.  Anogesic(R)  and  Tostrex(TM)  are
currently  undergoing Phase III clinical  trials.  Tostrelle(TM) is undergoing a
Phase I/II clinical trial.

     Clinical  Trials.  The Anogesic(R)  Phase III clinical trial is intended to
demonstrate reduction in pain of chronic anal fissures. The trial is designed to
include  approximately  165 to 180 patients enrolled at several study centers in
the United States and overseas  locations.  The study  protocol was developed by
Cellegy,  and  the  trial  is  being  monitored  by  outside  contract  research
organizations  under  Cellegy's  guidance.  Cellegy  expects  to file a New Drug
Application,  or  NDA,  by  the  end  of  2001,  assuming  no  unforeseen  trial
recruitment  delays  and  successful  clinical  trial  results.  Cellegy is also
conducting  Phase  II  trials   evaluating   Anogesic(R)  in  the  treatment  of
hemorrhoids and post-surgical hemorrhoidectomy pain.

     The  Tostrex(TM)  Phase III  clinical  trial is designed to restore  normal
levels of testosterone in men with testosterone deficiency, a condition known as
male hypogonadism.  The trial is being conducted at several study centers in the
United States and is being monitored by Cellegy and an outside contract research
organization.  The trial is currently  designed to include  approximately 200 to
240  patients,  and we  expect  to file an NDA by the end of 2001,  assuming  no
unexpected delays and successful clinical trial results.

     Tostrelle(TM)  is at an early stage of clinical  development  compared with
Anogesic(R)  and  Tostrex(TM).  One Phase  I/II study has been  completed  which
evaluated testosterone  concentrations  following varying doses of Tostrelle(TM)
given to post  menopausal  women. We recently began an expanded Phase I/II trial
with  approximately  36 women in the United  Kingdom  designed to determine  the
optimal dosing regimen of Tostrelle(TM) in surgically-induced  menopausal women.
If this  trial  is  successful,  we plan to meet  with  the  U.S.  Food and Drug
Administration,  or the FDA, to discuss  future trials  including a larger Phase
II/III trial. A number of other factors will impact the timing,  size and design
of these more advanced clinical trials and final product approvals.

     In addition to prescription drugs, Cellegy is developing and testing a line
of  non-prescription  skin care  products.  One of its  product  blends is being
marketed through a major specialty retailer in the United States.


                                  RISK FACTORS

     Please  carefully  consider the specific factors set forth below as well as
the other  information  contained in, or  incorporated  by reference  into, this
prospectus  before  purchasing  shares  of our  common  stock.  This  prospectus
contains  forward-looking  statements that involve risks and uncertainties.  Our
actual  results  may differ  significantly  from the  results  discussed  in the
forward-looking statements.  Factors that might cause such a difference include,
but are not limited to, those discussed below.

                                       3
<PAGE>

We have a history  of  losses,  and we expect  losses to  continue  for at least
several years.

     Our accumulated  deficit as of September 30, 2000 was  approximately  $47.2
million.  We have never  operated  profitably  and,  given our planned  level of
operating expenses,  we expect to continue to incur losses for at least the next
several  years.  We plan to increase  our  operating  expenses as we continue to
devote  significant   resources  to  pre-clinical   studies,   clinical  trials,
administrative,  marketing  and patent  activities.  We have not  generated  any
significant  revenues from  royalties or licensing of our  technologies,  and we
expect that it will take several years for our major prescription products to be
approved in the larger pharmaceutical markets. Accordingly,  without substantial
revenues from new corporate collaborations,  royalties on product sales or other
revenue sources,  we expect to incur substantial and increased  operating losses
in the  foreseeable  future as our earlier  stage  potential  products move into
clinical  development,  and as we  invest  in  research  or  acquire  additional
technologies,  product candidates or businesses.  Our losses may increase in the
future,  and  even if we  achieve  our  revenue  targets,  we may not be able to
sustain or increase  profitability on a quarterly or annual basis. The amount of
future net losses, and the time required to reach profitability, are both highly
uncertain.  To achieve  sustained  profitable  operations,  we must, among other
things,  successfully  discover,  develop,  obtain regulatory  approvals for and
market  pharmaceutical or cosmeceutical  products.  We cannot assure you that we
will ever be able to achieve or sustain profitability.

Our clinical trial results are very difficult to predict in advance, and failure
of one or more clinical trials could adversely affect our business and our stock
price.

     Before  we  obtain  regulatory  approval  for the  commercial  sale of most
potential drug products,  we must demonstrate through  pre-clinical  studies and
clinical trials that the product is safe and efficacious for use in the clinical
indication  for which  approval is sought.  We cannot assure you that the FDA or
other  international  regulatory  authorities  will permit us to  undertake  any
future clinical trials for potential  products or to continue any of the current
clinical  trials.  To date,  we have not sought FDA approval to  distribute  any
products.  Moreover,  results of pre-clinical  studies and early clinical trials
may not be good  predictors  of results  that will be  obtained  in  later-stage
clinical trials.  We cannot assure you that Cellegy's present or future clinical
trials,  including for example,  the current Phase III clinical trials using our
Anogesic(R)  and  Tostrex(TM)  products,  or the current Phase I/II dose ranging
study for  Tostrelle(TM),  will demonstrate the results required for approval to
market these  potential  products or even to continue with  additional  clinical
development.  Because  of the  independent  and blind  nature of  certain  human
clinical testing, there will be extended periods during the testing process when
we will have only  limited,  or no,  access to  information  about the status or
results  of the  tests,  and  this  is the  case  with  our  current  Phase  III
Anogesic(R)  clinical trial. 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.  If
Anogesic(R) or Tostrex(TM)  fail to successfully  complete the current Phase III
trials or related clinical testing,  including  toxicology studies, our business
and stock price would be materially and adversely affected.

Possible FDA  regulation of our  cosmeceutical  products as drugs could prohibit
them from being commercialized.

     If the FDA attempted to regulate our cosmeceutical products as drugs rather
than  cosmetics,  we could be delayed or prevented  from marketing and receiving
revenues from sales of those products.  The term "cosmeceuticals" is not defined
in the  Food,  Drug  and  Cosmetics  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.  The FDA may contend that
one  or  more  cosmeceutical  products,   including  Cellegy'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, and
this could delay or prevent us from marketing these products.

The Company faces intense  competition from larger companies,  and in the future
Cellegy  may not have the  resources  required to develop  innovative  products.
Cellegy's products are subject to competition from existing products.

     The  pharmaceutical  and cosmeceutical  industries are 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.  Cellegy is much smaller in terms of
size and resources than

                                       4
<PAGE>

many of its  competitors in the United States and abroad,  which include,  among
others,  major  pharmaceutical,   chemical,   cosmetic,   consumer  product  and
biotechnology  companies,  specialized  firms,  universities  and other research
institutions.  Cellegy's competitors may succeed in developing  technologies and
products  that are more  effective  than any that we are  developing  and  could
render Cellegy's  technology and potential products obsolete and noncompetitive.
Many of these  competitors have  substantially  greater  financial and technical
resources,   clinical  production  and  marketing  capabilities  and  regulatory
experience.  In addition,  Cellegy's  products are subject to  competition  from
existing products. For example, Cellegy's Tostrex product, if commercialized, is
expected to compete with two currently marketed  transdermal patch products sold
by Alza  Corporation and one transdermal  testosterone  gel product  marketed by
Unimed/Solvay.  Cellegy's Anogesic product,  if  commercialized,  is expected to
compete  with  over-the-counter  products,  such as  Preparation  H marketed  by
American Home Products, and various other prescription products. As a result, we
cannot assure you that  Cellegy's  products  under  development  will be able to
compete  successfully  with  existing  products  or  innovative  products  under
development by other organizations.

The type and scope of patent  coverage we have may limit the commercial  success
of our products.

     Cellegy's  success  depends,  in part,  on our  ability  to  obtain  patent
protection for our products and methods,  both in the United States and in other
countries.  Several of Cellegy's products are based on existing compounds with a
history of use in humans but are being  developed by Cellegy for new therapeutic
use in skin  diseases.  Cellegy 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 we are attempting to develop.  Cellegy may not be able to prevent a
competitor from using our formulations or compounds for a different purpose.  We
cannot assure you that any  additional  patents will be issued to Cellegy,  that
the protection of any patents issued in the future will be commercially valuable
or that current or future patents will be held valid if subsequently challenged.

     The patent  position of companies  engaged in businesses  such as Cellegy'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.  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 Cellegy'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
us a competitive advantage. In addition, many other organizations are engaged in
research  and product  development  efforts in drug  delivery,  skin biology and
cosmeceutical   fields  that  may  overlap   with   Cellegy's   products.   Such
organizations 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 Cellegy.  These rights may prevent us from
commercializing  technology, or may require Cellegy to obtain a license from the
organizations to use the technology.  Cellegy may not be able to obtain any such
licenses that may be required on reasonable  financial 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.  Cellegy is subject to the risk that individuals
or organizations located in such countries will engage in development, marketing
or sales activities of Cellegy's products.

Our agreement  with the  University of California may be cancelled if milestones
are not achieved or renegotiated.

     In March 1994 we  entered  into an  exclusive  license  agreement  with the
University of California  giving us exclusive  rights to patent rights,  jointly
held by the University and Cellegy, to certain drug delivery  technologies.  The
University  may terminate the agreement if Cellegy does not achieve  development
and  performance  milestones.  In 1997  Cellegy and the  University  amended the
agreement  to  modify  and  extend  certain  development  and  commercialization
milestones.  The  current  milestones  are tied to the  achievement  of  certain
clinical,  regulatory or product  commercialization  goals over the next several
years.  We are currently  negotiating an amendment with the University to extend
some of the milestone dates. Cellegy has previously satisfactorily negotiated an
extension date on milestones associated with this agreement and believes that it
will be able to do so again. If an extension  cannot be negotiated,  a resulting
loss of  rights  to these  technologies  would  have a  material  effect on some
planned  products,  but no direct  impact  on our  current  products  undergoing
clinical trials.

Our product sales strategy involving corporate partners is highly uncertain.  No
new partnership agreements have been finalized.

                                       5
<PAGE>

     Cellegy is seeking to enter into agreements with certain corporate partners
granting rights to commercialize our lead products, Anogesic(R) and Tostrex(TM).
As of the date of this  prospectus,  however,  Cellegy has not entered  into any
agreements with third parties to commercialize  either product.  Cellegy may not
be able to establish any such collaborative arrangements.  Failure to enter into
any such arrangements could prevent,  delay or otherwise have a material adverse
effect on our ability to develop and market  Anogesic(R),  Tostrex(TM)  or other
products  (particularly  in  certain  international  markets)  that we desire to
commercialize  through  third  party  arrangements,  and we  may  not  have  the
resources or the experience to successfully  commercialize  any such products on
our own.  Similarly,  if we are  unable to find  another  corporate  partner  to
develop or market our cosmeceutical  products, they may never be commercialized.
If we are able to enter into one or more corporate partner arrangements,  we may
rely on our partners to conduct clinical  trials,  obtain  regulatory  approvals
and, if approved,  manufacture and market or co-promote these products. However,
reliance   on  third   party   partners   can  create   risks  to  our   product
commercialization  efforts.  Once  agreements  are  completed,  Cellegy may have
little or no control over the development of these potential products and little
or no opportunity to review clinical data before or after public announcement of
results.   Further,  any  arrangements  that  may  be  established  may  not  be
successful.

We are subject to regulation by regulatory  authorities including the FDA, which
could delay or prevent marketing of our products.

     Cellegy's  prescription  products,  and our ongoing  research  and clinical
activities   such  as  those   relating   to   Anogesic(R),   Tostrex(TM),   and
Tostrelle(TM),  are subject to extensive  regulation by governmental  regulatory
authorities  in  the  United  States  and  other  countries.  Extensive  current
pre-clinical  and clinical  testing  requirements  and the  regulatory  approval
process  of the FDA in the  United  States  and of  certain  foreign  regulatory
authorities, or additional future government regulations, could prevent or delay
regulatory   approval  of  Cellegy's   products.   Notwithstanding  our  current
relationships with those authorities, disagreements may occur in the future, and
one or more of our  ongoing  or  planned  clinical  trials  could be  delayed or
repeated  in order to  satisfy  regulatory  requirements.  For  example,  if our
expanded Phase I/II trial regarding Tostrelle(TM) is successful, we plan to meet
with the FDA to discuss future trials, and the FDA could impose  requirements on
future  trials  that  could  delay the  regulatory  approval  process.  Sales of
Cellegy's   products  outside  the  United  States  are  subject  to  regulatory
requirements   governing   clinical   trials  and  marketing   approval.   These
requirements vary widely from country to country and could delay introduction of
Cellegy's products in those countries.

Our prospects for obtaining additional financing, if required, are uncertain and
failure to obtain needed financing could affect our ability to develop or market
products.

     Throughout our history,  we have consumed  substantial amounts of cash. Our
cash needs are expected to continue to increase  significantly over at least the
next several years in order to fund the additional  expenses  required to expand
our current research and development programs.  Cellegy has no current source of
significant  ongoing  revenues or capital beyond existing cash and  investments,
and certain  product  sales of  Rectogesic  in  Australia  and to  Gryphon,  the
development  subsidiary of a major specialty retailer.  In order to complete the
research and development and other  activities  necessary to  commercialize  our
products, additional financing will be required.

     Cellegy  will  seek  private  or  public  equity   investments  and  future
collaborative  arrangements  with third  parties to help fund future cash needs.
Such funding may not be available on acceptable  terms, if at all.  Insufficient
funding may require  Cellegy to delay,  reduce or  eliminate  some or all of our
research and development activities or planned clinical trial programs.  Cellegy
believes that available  cash resources and interest  earned will be adequate to
satisfy its capital needs through at least December 31, 2001.

We  currently  have no  products we sell on our own and have  limited  sales and
marketing experience.

     We may market  certain  of our  products,  if  successfully  developed  and
approved,  through a direct sales force in the United  States and through  sales
and  marketing  partnership  or  distribution  arrangements  outside  the United
States. Cellegy has very limited experience in sales, marketing or distribution.
To market our products  directly,  we intend to establish a marketing  group and
direct  sales  force in the  United  States  or  obtain  the  assistance  of our
marketing  partner.  If we enter into marketing or licensing  arrangements  with
established  pharmaceutical companies, our revenues will be subject to the terms
and conditions of such  arrangements and will be dependent on the efforts of our
partner. Cellegy may not be able to successfully establish a direct sales force,
or assure  you that our  collaborators  may not  effectively  market  any of our
potential products, and either circumstance could have a material adverse effect
on our business and stock price.

                                       6
<PAGE>

We have not  manufactured  products before and are dependent on a limited number
of critical suppliers.

     Cellegy has no direct experience in manufacturing  commercial quantities of
products and currently does not have any capacity to  manufacture  products on a
large  commercial  scale.  We  currently  rely on a limited  number of  contract
manufacturers and suppliers to manufacture our formulations. Although we believe
that there will be adequate third party manufacturers, there can be no assurance
that we will be able to enter  into  acceptable  agreements  with  them.  In the
future,  we may not be able to obtain  contract  manufacturing  on  commercially
acceptable  terms for  compounds or product  formulations  in the  quantities we
need.  Manufacturing  or quality  control  problems  could occur at the contract
manufacturers  such that they may not be able to  maintain  compliance  with the
FDA's current good  manufacturing  practice  requirements  necessary to continue
manufacturing our products.

We have  very  limited  staffing  and will  continue  to be  dependent  upon key
employees

     Our  success is  dependent  upon the  efforts of a small  management  team,
including K. Michael Forrest, our chief executive officer. We have an employment
agreement with Mr. Forrest and certain other officers,  but none of our officers
is bound by an  employment  for any  specific  term.  If key  individuals  leave
Cellegy,  we could be adversely affected if suitable  replacement  personnel are
not quickly  recruited.  Our future success depends upon our ability to continue
to attract and retain qualified  scientific,  marketing and technical personnel.
There is intense  competition for qualified  personnel in all functional  areas,
and  competition  particularly in the San Francisco Bay Area where our principal
facility is located, which make it difficult to attract and retain the qualified
personnel necessary for the development and growth of our business.

We are subject to the risk of product liability lawsuits.

     The testing,  marketing and sale of human health care  products  entails an
inherent risk of  allegations of product  liability.  We are subject to the risk
that  substantial  product  liability claims could be asserted against us in the
future.  Cellegy has obtained $4 million in insurance  coverage  relating to our
clinical  trials.  There can be no assurance that Cellegy will be able to obtain
or maintain insurance on acceptable terms,  particularly in overseas  locations,
for clinical and  commercial  activities  or that any  insurance  obtained  will
provide adequate protection against potential liabilities.

Our stock price could be volatile.

     Our stock  price has from time to time  experienced  significant  price and
volume  fluctuations.   Sometimes  our  stock  price  has  varied  depending  on
fluctuations in the Nasdaq National Market generally, and sometimes fluctuations
have resulted from matters more specific to Cellegy,  such as an announcement of
clinical trial results or other corporate developments. Announcements that could
significantly impact our stock price include:

     o  clinical   trial   results,   such  as  results  of  the   Anogesic(R)or
        Tostrex(TM)trials;

     o  developments or disputes concerning patent or proprietary rights;

     o  publicity  regarding actual or potential  clinical results or regulatory
        developments  relating  to  our  products  under  development  or by our
        competitors; and

     o  period-to-period   fluctuations  in  our  financial  results,  including
        operating expenses or profits.


                                 USE OF PROCEEDS

     If the warrants described under "Selling  Shareholders" below are exercised
for cash,  then we would  receive the proceeds  from  exercise of the  warrants.
However,  we will not receive any proceeds  from the sale of the common stock by
any of the selling shareholders.


                              SELLING SHAREHOLDERS

     We are  registering  the shares of common stock  pursuant to the  following
agreements:

                                       7

<PAGE>


     o  a Common  Stock  Purchase  Agreement  dated as of  October  2, 2000 (the
        "October  2000  Agreement"),  by  and  among  Cellegy  and  the  selling
        shareholders named below under the heading "October 2, 2000 Purchasers";

     o  a warrant  dated March 21,  2000 by Cellegy  and  Gruntal & Co.  L.L.C.,
        dated March 21, 2000, to purchase  150,000  shares of common stock at an
        exercise price of $8.50 per share at any time or from time to time after
        March 21, 2001 until March 21, 2004;

     o  a warrant  dated  March 21,  2000,  granted  by  Cellegy  to  Gruntal to
        purchase  150,000  shares of common stock at an exercise price of $15.00
        per share, at any time from September 21, 2001 until March 21, 2004;

     o  a warrant dated June 13, 2000 granted by Cellegy to Richcone Pty Ltd, to
        purchase up to 171,146  shares of common  stock at an exercise  price of
        $6.60 per share, expiring June 13, 2002;

     o  the Stock  Purchase  Agreement  dated as of April 14,  2000 by and among
        Cellegy,  Quay Pharmaceuticals Pty Ltd ACN 084 808 882, Richcone Pty Ltd
        ACN 064 469 861,  Cellegy  Australia  Pty Ltd ACN 092 129  596,  and Dr.
        David Z. Lubowski (the "Cellegy Australia Agreement"); and

     o  a warrant  dated  February 25, 2000 granted by Cellegy to Marc Parham to
        purchase  up to 3,500  shares of common  stock at an  exercise  price of
        $6.8125 per share in consideration of services provided to Cellegy.

     The warrants to Gruntal were issued in connection with an agreement between
Gruntal  and Cellegy for Gruntal to provide  financial  strategy  and  corporate
development advice and services.

     The following table sets forth information based on Cellegy's  knowledge as
of the date of this prospectus, with respect to the selling shareholders and the
shares of the  common  stock that may be offered  pursuant  to this  prospectus.
Except as described below,  none of the selling  shareholders has, or within the
past three years has had, any position,  office or other  material  relationship
with us or any of our predecessors or affiliates.

     Each selling shareholder represented to us, in their respective agreements,
that they  were  purchasing  such  shares  for  investment  and with no  present
intention of distributing or reselling such securities.  However, in recognition
of the fact that each such  shareholder,  even though purchasing such shares for
investment,  wishes to be legally  permitted  to sell the shares  when they deem
appropriate, we are filing this registration statement. Upon effectiveness,  the
selling  shareholders  may from time to time  offer and sell any or all of their
shares pursuant to this  prospectus.  Because the selling  shareholders  are not
obligated to sell shares of common stock,  and because selling  shareholders may
also acquire  publicly traded shares of our common stock, we cannot estimate how
many shares of common stock each selling shareholder will beneficially own after
this offering.

     Four Partners is a New York general partnership, the sole partners of which
are Andrew H.  Tisch  1991  Trust,  for which  Andrew H.  Tisch is the  managing
trustee,  Daniel R. Tisch 1991 Trust,  for which Daniel R. Tisch is the managing
trustee,  James S. Tisch 1991 Trust,  for which  James S. Tisch is the  managing
trustee,  and  Thomas J.  Tisch  1991  Trust,  for which  Thomas J. Tisch is the
managing  trustee.  Four Partners might be deemed to be the beneficial  owner of
the  shares  of  common  stock  owned by the 1999  Annuity  Trust I and the 2000
Annuity Trust VI, by James S. Tisch as custodian enumerated above.

     Cellegy  has an  agreement  that so long as Four  Partners  and persons and
entities  associated  with Four  Partners  and/or the Tisch  Family own at least
1,250,000  shares of Cellegy  Common Stock,  that Cellegy will,  upon request of
such  shareholders,  increase the authorized  number of the members of Cellegy's
Board of Directors and cause one designee of such  shareholders  to be nominated
and  elected to fill one such  position on the Board of  Directors.  Pursuant to
that agreement, Felix Baker was designated and elected a director of Cellegy. In
December 2000, Julian C. Baker was also elected a director of Cellegy.

     Pursuant to the Cellegy Australia Agreement,  in June 2000 Cellegy acquired
all of the outstanding shares of Cellegy Australia.  Before that date,  Richcone
and  Quay  Pharmaceuticals  had  to  transferred  to  Cellegy  Australia  assets
consisting  primarily  of  Quay's  product,   named  Rectogesic   (nitroglycerin
ointment), for the treatment of anal fissures, and related intellectual property
and assets relating to the Australian and South African markets.

                              PLAN OF DISTRIBUTION

     We have filed a  Registration  Statement of which this  prospectus  forms a
part  pursuant to  registration  rights we granted to the  selling  shareholders
pursuant to the October 2000 Agreement, the Cellegy Australia Agreement, and the
Gruntal Warrants.

     To our knowledge,  no selling  shareholder  has entered into any agreement,
arrangement or  understanding  with any  particular  broker or market maker with
respect  to the  shares  of  common  stock  offered  hereby,  nor do we know the
identity of the brokers or market  makers that will  participate  in the sale of
the shares. As used in this prospectus, the term "selling shareholders" includes
donees and pledgees  selling  shares  received from a named selling  shareholder
after the date of this prospectus.

     Who May Sell; How Much; Applicable  Restrictions.  The selling shareholders
may from time to time offer the shares of common stock through brokers,  dealers
or agents who may receive compensation in the form of discounts,  concessions or
commissions from the selling shareholders and/or the purchasers of the shares of
common stock for whom they may act as agent. In effecting sales,  broker-dealers
that  are   engaged  by  the   selling   shareholders   may  arrange  for  other
broker-dealers  to participate.  The selling  shareholders and any such brokers,
dealers or agents who  participate in the  distribution  of the shares of common
stock may be deemed to be  "underwriters,"  and any  profits  on the sale of the
shares of common stock by them and any  discounts,  commissions  or  concessions
received  by  any  such  brokers,  dealers  or  agents  might  be  deemed  to be
underwriting  discounts and commissions  under the Securities Act. To the extent
the  selling  shareholders  may  be  deemed  to  be  underwriters,  the  selling
shareholders may be subject to certain  statutory  liabilities of, including but
not  limited to,  Sections  11, 12 and 17 of the  Securities  Act and Rule 10b-5
under  the  Exchange  Act.  To our  knowledge,  there  are  currently  no plans,
arrangements or understandings  between any selling shareholders and any broker,
dealer, agent or underwriter regarding the sale of the shares of common stock by
the selling shareholders.

     Manner of Sales and Applicable Restrictions.  The selling shareholders will
act  independently  of Cellegy in making  decisions  with respect to the timing,
manner  and size of each  sale.  Such  sales may be made over the  Nasdaq  Stock
Market or otherwise,  at then  prevailing  market  prices,  at prices related to
prevailing market prices or at negotiated prices. The shares of common stock may
be sold according to one or more of the following methods:

         (a)  a block  trade in which  the  broker or  dealer  so  engaged  will
              attempt  to sell the  shares  of  common  stock  as agent  but may
              position  and  resell  a  portion  of the  block as  principal  to
              facilitate the transaction;

pursuant to Rule 144 or Rule 144A of the  Securities  Act 1933 may be sold under
Rule 144 or Rule 144A rather than pursuant to this  prospectus.  In addition,  a
selling  shareholder may transfer,  devise or gift the shares by other means not
described in this prospectus.

     Certain persons  participating  in this offering may engage in transactions
that  stabilize,  maintain or  otherwise  affect the price of our common  stock,
including the entry of stabilizing  bids or syndicate  covering  transactions or
the  imposition of penalty bids. The selling  shareholders  and any other person
participating in such distribution  will be subject to applicable  provisions of
the Exchange Act and the rules and  regulations  thereunder  including,  without
limitation, Regulation M (which regulation may limit the timing of purchases and
sales of any of the shares of common stock by the selling  shareholders  and any
other such person). The anti-manipulation rules under the Exchange Act may apply
to sales of shares of common  stock in the market and to the  activities  of the
selling  shareholders  and their  affiliates.  Furthermore,  Regulation M of the
Exchange Act may restrict the ability of any person engaged in the  distribution
of the shares of common stock to engage in market-making activities with respect
to the particular shares of common stock being distributed for a period of up to
five business days prior to the  commencement of such  distribution.  All of the
foregoing  may affect the  marketability  of the shares of common  stock and the
ability  of any  person or entity to  engage in  market-making  activities  with
respect to the shares of common stock.

     Rules 101 and 102 of  Regulation  M under the  Exchange  Act,  among  other
things,  generally prohibit certain  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 of Regulation M governs bids and purchases  made to stabilize the price of a
security in connection with a distribution of the security.

     Hedging and Other Certain Transactions with  Broker-Dealers.  In connection
with  distributions  of the shares of common  stock or  otherwise,  the  selling
shareholders  may  enter  into  hedging  transactions  with  broker-dealers.  In
connection with such  transactions,  broker-dealers may engage in short sales of
the shares of common  stock  registered  hereunder  in the course of hedging the
positions they assume with selling  shareholders.  The selling  shareholders may
also sell shares of common stock short and  redeliver the shares of common stock
to close out such short positions.  The selling shareholders may also enter into
option or other transactions with  broker-dealers  which require the delivery to
the broker-dealer of the shares of common stock registered hereunder,  which the
broker-dealer  may resell or  otherwise  transfer  pursuant to this  prospectus.
Selling  shareholders  may also  loan or  pledge  the  shares  of  common  stock
registered  hereunder  to a  broker-dealer  and the  broker-dealer  may sell the
shares of common  stock so loaned or,  upon a  default,  the  broker-dealer  may
effect sales of the pledged shares of common stock pursuant to this prospectus.

     Expenses  Associated With Registration.  We have agreed to pay the expenses
of registering  the shares of common stock under the Securities  Act,  including
registration and filing fees,  printing  expenses,  administrative  expenses and
certain legal and accounting  fees. Each of the selling  shareholders  will bear
its pro rata share of all  discounts,  commissions  or other amounts  payable to
underwriters,  dealers  or  agents as well as fees and  disbursements  for legal
counsel retained by any such selling shareholder.

     Indemnification.  Under  the  terms of the  Agreement,  we have  agreed  to
indemnify each of the parties to the Agreement and certain other persons against
certain  liabilities  in  connection  with the  offering of the shares of common
stock, including liabilities arising under the Securities Act.

     Prospectus Updates;  Suspension of this Offering.  At any time a particular
offer of the shares of common stock is made, a revised  prospectus or prospectus
supplement,  if required,  will be distributed.  Such  prospectus  supplement or
post-effective amendment will be filed with the SEC to reflect the disclosure of
required  additional  information with respect to the distribution of the shares
of common stock.  Under the terms of the  Agreement,  upon the occurrence of any
event known to our  executive  officers as a result of which this  prospectus is
known by our  executive  officers to include an untrue  statement  of a material
fact or omits  to  state a  material  fact  required  to be  stated  therein  or
necessary  to make the  statements  therein not  misleading  in the light of the
circumstances then existing, the parties have each agreed not to trade shares of
common stock from the time the selling shareholder  receives notice from Cellegy
of such an event until such party receives a prospectus supplement or amendment.
Upon the occurrence of such an event, a prospectus  supplement or post-effective
amendment, if required, will be distributed to the parties.

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.

     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

                                       15
<PAGE>


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 facts or events arising
after the  effective  date of the  Registration  Statement  (or the most  recent
post-effective  amendment  thereof)  which,  individually  or in the  aggregate,
represent a fundamental change in the information in the Registration Statement;
and (iii) to  include  any  material  information  with  respect  to the plan of
distribution  not  previously  disclosed  in the  Registration  Statement or any
material change to such  information in the  Registration  Statement;  provided,
however,  that  (i) and  (ii) do not  apply if the  information  required  to be
included in a post-effective  amendment thereby is contained in periodic reports
filed  by  the  Registrant  pursuant  to  Section  13 or  Section  15(d)  of the
Securities  Exchange Act of 1934 (the "Exchange  Act") that are  incorporated by
reference in the Registration Statement.

     (2) That, for the purpose of determining any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

                                       16
<PAGE>

     (3) To remove from registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     (4) That,  for purposes of determining  any liability  under the Securities
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  Registration  Statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
