Prospectus                                                 Subject to Completion
                                                                   June 18, 1996
                           UNIGENE LABORATORIES, INC.

                        6,708,408 -Shares of Common Stock
                           (par value $.01 per share)


         The 6,708,408 shares of common stock, $.01 par value per share ("Common
Stock") offered hereby are issuable upon the exercise of outstanding  Redeemable
Class B Common Stock  Purchase  Warrants  ("Class B Warrants").  The  registered
holder of each Class B Warrant is entitled to purchase  1.1992  shares of Common
Stock at $4.1694 per share on or prior to August 11, 1996. The exercise price of
the Class B Warrants  is subject to  adjustment  in certain  circumstances.  The
Class B Warrants  are  subject to  redemption  at $0.0417  per warrant on thirty
days'  written  notice,  provided  the closing bid price of the Common  Stock as
reported  by NASDAQ  (or the last sale  price  listed on a  national  securities
exchange),  for thirty  consecutive  business days ending within fifteen days of
the  notice  of  redemption  averages  in  excess  of  $5.8372  per  share.  See
"Description of Securities".

         Each Class B Warrant was issued upon exercise of previously outstanding
Redeemable  Class A Common Stock  Purchase  Warrants  ("Class A Warrants").  The
Class A Warrants  were  included in units  ("Units").  Each Unit,  consisting of
three shares of Common Stock and three Class A Warrants, was sold by the Company
in its initial public offering  pursuant to a Prospectus  dated August 12, 1987.
The registered holder of each Class A Warrant was entitled to purchase for $3.25
one share of  Common  Stock and to  receive  one Class B Warrant  on or prior to
August 11,  1992.  In May 1991,  the  Company  announced  that it would call for
redemption on July 3, 1991 at a redemption price of $.05 per Warrant, all of the
then  outstanding  Class A Warrants.  A total of 5,594,069 Class A Warrants were
exercised  resulting  in the  issuance  of  5,594,069  shares of  Common  Stock,
5,594,069  Class B Warrants  and the receipt by the  Company of net  proceeds of
$17,434,000. The balance of the outstanding Class A Warrants were redeemed.

         In December 1994 and November  1995, as a result of private  placements
of Common  Stock and  issuance of warrants  to purchase  Common  Stock at prices
below  the  exercise  price  of  the  Class  B  Warrants,  and  pursuant  to the
requirements of the Warrant  Agreement,  Unigene  adjusted the exercise price of
its Redeemable Class B Common Stock Purchase  Warrants from $5.00 to $4.1694 per
share and adjusted the number of shares of Common Stock thereby  exercisable for
each  Class B Warrant  from 1 share of Common  Stock to 1.1992  shares of Common
Stock.  As a consequence of the adjustment of the price of the Class B Warrants,
the Redemption Price of the Class B Warrants was adjusted from $0.05 per Warrant
to $.0417 per  Warrant,  the market  price of the Common  Stock  required  to be
exceeded  in order for the  Company  to  exercise  its right of  redemption  was
adjusted  from  $7.00 per share to  $5.8372  per share and the  number of shares
issuable was adjusted from 5,594,069 to 6,708,408.

         The  Company's  Common  Stock and Class B Warrants  have  traded in the
over-the-counter  market since  August 12, 1987 and May 28, 1991,  respectively.
The Common Stock is traded on the NASDAQ National Market System under the market
symbol "UGNE" and the Warrants  under the symbol  "UGNEZ".  On June 7, 1996, the
closing  price for a share of Common Stock was $3.75 and the closing price for a
Class B Warrant was $1.13 according to NASDAQ.

                                  RISK FACTORS

         Prospective  investors should consider  carefully the following factors
concerning the Company and its business before purchasing  securities offered by
this Prospectus.

         Absence  of  Operating  Revenues  and  Liquidity;  History  of  Losses;
Auditors' Report - Going Concern Considerations. The Company has incurred annual
operating losses since its inception and, as a result, at March 31, 1996, had an
accumulated deficit of $35,700,000. The Company has not received any significant
operating revenues during the last five years.

         In addition to operating its production  facility and seeking  approval
for its  Calcitonin  for human use,  the  Company  intends to  continue  certain
internally  funded  research  activities such as the development of a Calcitonin
pill, all of which will contribute to continuing losses from operations.  All of
the Company's  contracts to perform  sponsored  research have been  completed or
cancelled and, at present, it has almost no operating  revenues.  It is unlikely
that the Company's  operating  results will improve unless it is able to license
its  technology,  obtain new  projects,  or  successfully  produce  and sell its
products.  The Company may continue to incur losses over the next several years.
The  auditors'  report for the fiscal year ended  December 31, 1995  contains an
explanatory  paragraph indicating there is substantial doubt about the Company's
ability to continue as a going concern.

         The  Company  has  sufficient   financial   resources  to  sustain  its
operations at the current level through approximately the third quarter of 1996.
To continue its operations  beyond that time will require that the Company enter
into additional financing transactions or marketing,  joint venture or licensing
agreements.  There can be no assurance  that any such  financings  will occur or
that any such agreements will be entered into by the Company.

         Transition  to  Production;  Possibility  of  Delays  or  Inability  to
Manufacture  and  Market  Products.   The  Company  is  currently  undergoing  a
transition  from its historical  research  orientation  toward a business with a
pharmaceutical production focus. Accordingly, the Company is likely to incur the
problems, delays, expenses and difficulties typically encountered by enterprises
in the Company's stage of transition,  many of which may be beyond the Company's
control.

         No  product  of  the   Company  has  been   commercialized   for  human
pharmaceutical use. The commercial manufacture and sale of any such product will
require the  approval of the U.S.  Food and Drug  Administration  ("FDA") and by
comparable  regulatory  authorities  outside  of the  United  States.  See "Risk
Factors -  Government  Regulation."  There  can be no  assurance  that  clinical
testing  will be  successful  or that the  clinical  results will be adequate to
support regulatory submissions.  Furthermore, there can be no assurance that the
Company's  products will be  demonstrated  to be safe and effective or that they
will be approved by the  appropriate  regulatory  authorities.  Even if any such
products are approved,  there is no assurance that they can be  manufactured  in
commercial  quantities  at  reasonable  costs.  Due  to  the  Company's  limited
clinical, manufacturing and regulatory experience and the absence of a marketing
organization,  it may be necessary  for the Company to rely on sponsors or other
parties to perform such tasks for the commercialization of  pharmaceutical-grade
products. See "Risk Factors - Dependence on Large Pharmaceutical Companies."

         Expanded consumer acceptance of pharmaceutical-grade  Calcitonin may be
dependent on development of a consumer  acceptable  delivery system. The Company
and others are  conducting  research  on new  delivery  systems  for  Calcitonin
including  oral  technology.  There can be no  assurance  that the Company  will
develop suitable oral delivery systems or that governmental approval of any such
delivery  system will be obtained.  There can also be no  assurance  that others
will not develop  oral or other  delivery  systems  that could  compete  with or
surpass any oral delivery system developed by the Company.  Moreover,  there are
non-Calcitonin  products currently being marketed for osteoporosis treatment and
other  non-Calcitonin  products in development that will compete with Calcitonin
products. See "Risk Factors - Technological Change and Competition."

         There  can be no  assurance  that  the  Company  will  have  sufficient
financial  resources  to fund its  operations  until  such time as it is able to
generate  revenues  that are  sufficient  to sustain its  operations.  See "Risk
Factors - Absence  of  Operating  Revenues  and  Liquidity;  History  of Losses;
Auditors' Report - Going Concern Considerations."

         New   Production   Facility.   During  1994,   the  Company   completed
construction of a facility for the production of pharmaceutical-grade Calcitonin
and other peptide hormones.  The Company is leasing the facility under a 10-year
agreement  which began in  February  1994.  The Company has two 10-year  renewal
options  as  well  as an  option  to  purchase  the  facility.  The  Company  is
undertaking  steps to secure FDA validation of the facility which would allow it
to manufacture  Calcitonin for human  pharmaceutical use. The facility has begun
producing  Calcitonin in  accordance  with current Good  Manufacturing  Practice
("cGMP")  regulations,  but  there is no  assurance  that the  facility  will be
approved by the FDA.  Furthermore,  there can be no assurance  that the facility
will be able to achieve its production  goals,  that production at this facility
will be  profitable to the Company,  that others will not develop  processes and
products  superior  to, or  otherwise  precluding  the Company  from  commercial
utilization  of this  facility,  that there  will be a market for the  Company's
products  produced by the facility,  or that sufficient  funds will be available
for the Company to complete the pre-production  process or to produce and market
its products from the facility.

         Dependence on Large Pharmaceutical  Companies. The Company has been and
expects to  continue  to be  dependent  on large  pharmaceutical  companies  for
revenues  from  sales of  product,  research  sponsorship,  joint  ventures  and
licensing arrangements.  During the 1987 to 1990 period, the Company's operating
revenues  resulted  primarily from research  which was totally or  substantially
funded by  pharmaceutical  companies.  The Company  currently  has no  sponsored
research projects.  There is no assurance that the Company will be successful in
its efforts to enter into new research or licensing  agreements or other revenue
producing arrangements.

         The  Company's  past  contracts  with  certain  pharmaceutical  company
sponsors  provide for payment of royalties to the Company on commercial sales of
the products of sponsored research projects.  However, there can be no assurance
that such  sponsors  will  successfully  commercialize  any product based on the
Company's technology. It currently is unlikely that the Company will receive any
material royalties under such past agreements.

         In June 1995, the Company  entered into a joint venture  agreement with
the Qingdao  General  Pharmaceutical  Company and its  Huanghai  factory for the
production  and  marketing of  Calcitonin  in China.  Under the  agreement,  the
Chinese  partners  will  finance the project,  including  the  construction  and
operation of a dedicated  manufacturing facility in China which will utilize the
Company's propriety  production  technology.  The Company will provide the joint
venture with technology and training as well as the Company's proprietary enzyme
at a discounted  price. The Company will receive a combination of fixed fees and
minimum  annual  royalties  based  upon  sales of the end  product.  There is no
assurance  that this joint  venture will be  successful or that the Company will
receive significant income from the joint venture.

         Risks  of  International  Operations.  The  Company's  potential  major
customers,  partners and licensees  include foreign  companies or companies with
significant  international  business.  The business operations of such companies
and their  ability to pay  license  fees,  royalties  and other  amounts due and
otherwise to perform their  obligations to the Company under agreements with the
Company may be subject to approval or regulation by foreign  governments.  There
can be no assurance  that required  approvals  will be received.  The failure to
receive required approvals,  governmental regulations and other risks, including
political and foreign currency risks, could affect the ability of the Company to
earn or receive  payments  pursuant to such agreements  and, in such event,  may
have a material adverse effect on the Company's future operations.

         Technological Change and Competition. The Company has concentrated most
of its  efforts on one  product - the use of  Calcitonin  for the  treatment  of
osteoporosis. The market for this treatment of osteoporosis is subject to rapid,
unpredictable and significant technological change. Competition from specialized
biotechnology  companies,   major  pharmaceutical  and  chemical  companies  and
universities  and research  institutions is intense.  Most of the competitors of
the Company have  substantially  greater financial and other resources than does
the Company.  There can be no assurance that  developments by others,  including
alternative chemical means of amidation,  alternative  processes which eliminate
the  need  for  amidation,  and new  delivery  systems  and  other  osteoporosis
treatments,  will not render the  Company's  technologies  and products  derived
therefrom obsolete or noncompetitive.

         Product  Liability.  Product liability claims relating to the Company's
technology  or products  may be asserted  against the  Company.  There can be no
assurance that the Company will have  sufficient  resources to defend against or
satisfy any such liability.  Although the Company has recently  obtained product
liability insurance  coverage,  product liability or other judgments against the
Company in excess of insurance  limits could have a material adverse effect upon
the Company's business and financial condition.

         Patents and Proprietary Technology.  The Company has filed applications
for  U.S.  patents  relating  to  the  proprietary  amidation  and  immunization
processes and Calcitonin  pill invented in the course of its research.  To date,
the following two patents have issued:  Immunization By Immunogenic  Implant,  a
process patent, and Alpha-Amidation  Enzyme, a process and product patent. Other
applications  are pending.  Filings  related to the amidation  process have also
been made in selected  foreign  countries  and nine such  foreign  patents  have
issued. There can be no assurance that any of the Company's pending applications
will issue as patents or that the  Company's  issued  patents  will  provide the
Company with significant  competitive advantages.  Furthermore,  there can be no
assurance that competitors will not  independently  develop or obtain similar or
superior  technologies.  Although  the Company  believes  its patents and patent
applications are valid, the invalidation of its Alpha-Amidation Enzyme patent or
the   failure  of  certain  of  its   pending   Alpha-Amidation   Enzyme-related
applications  to issue as patents could have a material  adverse effect upon the
Company's  business.  Difficulties  in detecting  and proving  infringement  are
generally  greater with process patents than with product patents.  In addition,
the  value of a  process  patent  may be  reduced  if the  products  that can be
produced   using  such  process  have  been  patented  by  others.   Under  such
circumstances,  the  cooperation of these patent  holders or their  sublicensees
would  be  needed  for  the  commercialization  of the  aforementioned  patented
products in countries where these companies hold valid patents.

         In some  cases,  the  Company  relies on trade  secrets to protect  its
inventions.  It is the  policy  of  the  Company  to  include  in  all  research
contracts,  joint  development  agreements  and  consulting  relationships  that
provide access to the Company's trade secrets and other know-how confidentiality
obligations binding on the parties involved.  However, there can be no assurance
that these  secrecy  obligations  will not be breached to the  detriment  of the
Company.  To the extent  sponsors,  consultants  or other  third  parties  apply
technological  information  independently  developed  by  them or by  others  to
Company  projects,  disputes  may  arise as to the  proprietary  rights  to such
information which may not be resolved in favor of the Company.

         Government  Regulation.  The  laboratory  research  activities  of  the
Company and its sponsors,  collaborators  and  licensees,  and the processes and
products  which may be developed by them and the new  production  facility,  are
subject to significant regulation by numerous federal,  state, local and foreign
governmental  authorities.  In addition to obtaining the FDA's validation of the
new  facility,  it is  necessary  to obtain  FDA  approval  for human use of the
Calcitonin to be produced in the facility.  This will require  various human and
animal  studies.  The  Company  will then apply to the FDA for  approval  of the
Company's  Calcitonin for human use. The regulatory process for a pharmaceutical
product may take a number of years and requires  substantial  resources.  In the
case of the  regulatory  process  for the  Company's  Calcitonin  products,  the
Company  believes  that it may be possible to abbreviate  the process.  However,
there can be no assurance that regulatory  approval will be obtained for the new
facility or any of the Company's products. The inability to obtain, or delays in
obtaining,  such  approvals  would  adversely  affect the  Company's  ability to
continue  to fund its  programs,  produce  marketable  products,  or to  receive
revenue from product sales or royalties.  Furthermore, the extent of any adverse
governmental   regulation   that  may  arise   from   future   legislative   and
administrative action cannot be predicted.

         Dependence on Key Executives. Drs. Warren and Ronald Levy have been the
principal  executive  officers of the Company since its  inception.  The Company
relies on them for their leadership and scientific direction. Neither Dr. Warren
P. Levy nor Dr.  Ronald S. Levy has an  employment  agreement  with the Company.
Each of them has entered into an agreement  with the Company  providing  that he
shall not  engage in any other  employment  or  business  for the  period of his
employment  with the Company.  At the present time,  the loss of the services of
either  of  these  individuals  could  have a  material  adverse  impact  on the
Company's business.

         Attraction  and Retention of Key  Personnel.  The Company's  ability to
obtain required governmental  approvals,  produce its products,  obtain research
contracts  and  develop new  technologies  will depend in part on its ability to
attract and retain highly qualified scientific  personnel.  Competition for such
personnel is intense. There can be no assurance that the Company will be able to
attract and retain such personnel.

         Shares Eligible For Future Sale;  Outstanding  Convertible  Securities,
Warrants  And  Options.  Other than the  6,708,408  shares of Common Stock to be
issued to which this Prospectus  relates,  there are 7,692,201  shares of Common
Stock  that are  registered  under  the  Securities  Act and were  issued or are
issuable as follows:

         2,869,565  shares of Common  Stock were  issued or are  issuable by the
Company to holders of  $3,300,000  aggregate  principal  amount of the Company's
9.5% Senior Secured Convertible Debentures (the "Debentures") upon conversion of
the  Debentures;  the  Debentures  were  issued  by  the  Company  in a  private
transaction on March 6, 1996 and initially are convertible  into Common Stock at
a  conversion  rate of $1.15 per share.  3,681,536  shares of Common  Stock were
issued or are  issuable by the Company to holders  upon  exercise of warrants of
the Company (the  "Warrants");  the Warrants were issued by the Company  between
October 1994 and April 1996 in consideration of certain financial and consulting
services  performed for the Company or in  connection  with loans to the Company
and initially  are  exercisable  at prices  ranging from $1.375 to $3 per share.
115,000  shares of Common  Stock were  issued or are  issuable by the Company to
holders upon  exercise of options  granted by the Company (the  "Options");  the
Options  were  granted by the  Company  between  January  1993 and April 1996 in
consideration of certain  consulting  services  performed for the Company by the
holders  thereof and are  exercisable  at prices ranging from $1.4375 to $4.5625
per share.  826,000 shares of Common Stock were issued by the Company to certain
stockholders in a private placement  completed  February 1996. 200,100 shares of
Common  Stock were or will be issued by the  Company to certain  other  holders.
10,000 of such  shares  of Common  Stock  will be  issued in  consideration  for
services performed for the Company.  190,100 of such shares of Common Stock were
issued upon the exercise of options in connection with certain loans made to the
Company in 1985.  One of the  holders,  Jay Levy,  is one of the founders of the
Company  and  currently  serves as the  Chairman of the Board of  Directors  and
Treasurer of the Company.  Mr. Levy acquired  109,350  shares of Common Stock on
June 21, 1994 for $150,000 upon the exercise of such a stock option.


         In  addition,  as of June 7, 1996,  approximately  2,700,000  shares of
Common Stock are issuable  upon  conversion  of the balance of the Company's 10%
convertible debentures; and 1,609,265 shares are issuable under purchase options
exercisable  at prices  ranging  from  $1.00 to $3.00 per  share.  In  addition,
4,138,350 outstanding shares of Common Stock are "restricted securities" as that
term is  defined  by  Rule  144  promulgated  under  the  Securities  Act.  Such
restricted  securities may be sold only in compliance with Rule 144, or pursuant
to  registration  under the  Securities  Act or  pursuant  to another  exemption
therefrom.  The Company may issue additional  convertible  securities,  options,
warrants  and  shares  in  the  future.  Transactions  by  the  Company,  or the
occurrence  of certain  other  future  events,  may  require  adjustment  of the
exercise  or  conversion  price and  other  terms of the  Company's  convertible
securities,  options and warrants including, in some circumstances,  an increase
in the number of shares issuable thereunder.

         The Company  cannot  predict the  adverse  effect that market  sales of
Common Stock,  the conversion of such  convertible  securities,  the exercise of
such options or warrants, or the availability of Common Stock for sale will have
on the market price of the Common Stock  prevailing from time to time,  although
it is likely  that sales of a large  number of  securities  would  depress  such
market price.  The Company also cannot predict the adverse effect,  if any, that
such  convertible  securities,  options,  warrants and shares available for sale
will have on the  ability  of the  Company to obtain  additional  capital or the
terms and conditions thereof.

         Possible  Volatility  of  Securities  Prices.  The market prices of the
Company's  securities may be highly  volatile.  Factors such as announcements by
the Company or others of  technological  innovations,  regulatory  matters,  new
products  or  procedures,  proposed  government  regulations,   developments  or
disputes relating to patents or proprietary  rights, and public concern over the
safety of  activities  or products may have a  significant  impact on the market
price of the Company's securities. In addition, future sales of shares of Common
Stock by shareholders and by the holders of convertible securities, warrants and
options could have an adverse effect on the prices of the Company's  securities.
See "Risk  Factors - Shares  Eligible for Future Sale;  Outstanding  Convertible
Securities, Warrants and Options."

         Voting Control.  Warren P. Levy, Ronald S. Levy and Jay Levy,  founders
of the Company,  beneficially own,  approximately 16% of the outstanding  Common
Stock (assuming that outstanding  convertible  securities,  warrants and options
held by others are not converted or exercised)  and, thus,  effectively may have
the ability to elect the entire  Board of  Directors  and control the affairs of
the Company.

         Dividends.  The Company has not paid any cash  dividends  on its Common
Stock since its inception and anticipates  that, for the foreseeable  future, it
will not pay any cash dividends.

         Limitation of  Marketability  of Company  Securities.  The Common Stock
currently is traded on the Nasdaq National Market. In order for the Common Stock
to continue to qualify for inclusion on the Nasdaq National Market,  among other
requirements,  the  Company  must  have net  tangible  assets  of at least  $4.0
million.  As of March 31, 1996 the amount of the Company's  net tangible  assets
was  approximately  $3.0  million.  See "Risk  Factors -  Absence  of  Operating
Revenues and  Liquidity;  History of Losses;  Auditors'  Report - Going  Concern
Considerations."  If the  Company  is unable to develop a plan  satisfactory  to
Nasdaq by which it will be able to  restore  and  maintain  compliance  with the
Nasdaq National Market listing requirements,  it is likely that the Common Stock
will be removed from trading on the Nasdaq  National  Market.  Among the actions
that could restore an adequate level of net tangible assets is the conversion of
the Company's  outstanding  convertible  securities.  While the Company believes
that such  conversions  are  likely,  there is no  assurance  that the extent or
timing of such conversions will prevent the removal of the Common Stock from the
Nasdaq National Market. Likewise, there is no assurance that the Company will be
successful  in any other  actions that it might take to prevent a removal of the
Common Stock from the Nasdaq  National  Market or that the Company will continue
to meet all other  requirements  for  continued  trading on the Nasdaq  National
Market.  If the  Company's  fails to meet the  requirements  for  trading on the
Nasdaq  National  Market and does not  otherwise  qualify for  inclusion  in the
Nasdaq  Small-Cap  Market,  the holders of Common Stock may find it difficult to
obtain  accurate  quotations  as to the market value of the Common Stock and may
experience  greater  difficulties in attempting to sell the Common Stock than if
it were listed on a stock  exchange or quoted on the Nasdaq  National  Market or
the Nasdaq Small-Cap Market.

         If the Common Stock is not traded on the Nasdaq  National Market or the
Nasdaq Small-Cap  Market,  and the market price of the Common Stock is less than
$5.00 per share,  the Common Stock would be  classified  as a "penny  stock." As
such the Common  Stock  would be subject to Rule 15g-9 under the  Exchange  Act,
which imposes  additional  sales practice  requirements on  broker-dealers  that
recommend the purchase or sale of such securities to persons other than a person
who qualifies as an "established  customer" or an "accredited  investor."  Among
these  requirements  is that a  broker-dealer  must  make a  determination  that
investments  in penny stocks are suitable for the customer and must make certain
special  disclosures  to the  customer  concerning  the  risks of penny  stocks.
Application of the penny stock rules to the Common Stock could adversely  affect
the market liquidity of such securities, which in turn may affect the ability of
the holders of the Common Stock to resell the securities.


                                   THE COMPANY

         Unigene  Laboratories,  Inc. is a  health-care  oriented  biotechnology
company which is engaged in research and  production of cGMP  Calcitonin  and is
planning to engage in the  production  and  marketing in bulk of  pharmaceutical
grade  Calcitonin.  The  Company's  current  business  focus has shifted  toward
pharmaceutical production from its historical research orientation.  The Company
has  succeeded in combining its  proprietary  amidation  process with  bacterial
recombinant DNA technology to develop a peptide hormone production process.  The
Company  believes that its proprietary  amidation  process will be a key step in
the more  efficient and  economical  commercial  production  of certain  peptide
hormones with diverse therapeutic applications. Many of these hormones cannot be
produced at a reasonable cost in sufficient  quantities for clinical  testing or
commercial  use  by  currently  available   production   processes.   Using  its
proprietary  process,  the Company has produced  laboratory-scale  quantities of
seven such peptide hormones: human Calcitonin,  salmon Calcitonin,  human Growth
Hormone  Releasing  Factor,  human  Calcitonin   Gene-Related   Peptide,   human
Corticotropin Releasing Factor, human Amylin and a human Magainin.  During 1991,
a study  commissioned  by the  Company was  prepared by a professor  of chemical
engineering at the  Massachusetts  Institute of Technology.  The study evaluated
the  economics  for  producing  multi-kilogram   quantities  of  Calcitonin  and
indicated that the Company's process for producing  Calcitonin should reduce the
cost and time required for commercial production by up to 95%.

         The Company's strategy is to develop proprietary products and processes
with  applications in human  health-care,  independently  or in conjunction with
pharmaceutical  and  chemical  companies,  in order to  generate  revenues  from
license fees, royalties and product sales in bulk. Generally,  the Company seeks
sponsors and licensees to provide research funding and assume responsibility for
obtaining  appropriate  regulatory approvals,  clinical testing,  production and
marketing of products  derived from the Company's  research  activities.  It has
concentrated  most of its efforts on one product - Calcitonin  for the treatment
of  osteoporosis.  The  Company  has built a  production  facility  and plans to
undertake   production  of  pharmaceutical  grade  Calcitonin  and  will  assume
responsibility for the clinical testing and/or applying for regulatory  approval
for certain Calcitonin products.

         Since  1992,  the  Company  has been  producing  and from  time to time
selling small quantities of research-grade  salmon Calcitonin.  During 1993, the
Company  began   construction   of  a  cGMP  facility  for  the   production  of
pharmaceutical-grade  Calcitonin  in leased  premises  located in  Boonton,  New
Jersey which was  mechanically  completed during the fourth quarter of 1994. The
facility will also produce the Company's proprietary amidating enzyme for use in
producing  Calcitonin.  The  initial  production  capacity  of the  facility  is
expected  to  be  between   0.5-1.0   kilogram  of  bulk  Calcitonin  per  year,
representing  approximately  10% of the current  estimated world supply for this
leading osteoporosis drug.

         The Company is following conventional procedures in order to secure the
validation  of the  facility by the FDA in order to allow the Company to provide
its  Calcitonin  for human  use.  Although  the  facility  was  inspected  by an
independent consultant and found to be in compliance with cGMP guidelines, there
can be no assurance  that FDA  validation  will occur.  In addition  there is no
assurance that the facility  production goals will be achieved,  that there will
be a market for the Company's products,  that such production will be profitable
to the Company, that others will not develop processes and products superior to,
or otherwise precluding the commercial utilization of, the processes or products
developed  by the  Company.  The design of the facility is intended to allow for
substantial  increases in Calcitonin production utilizing the existing equipment
with no additional capital expenditures or personnel. Although the facility will
initially be exclusively devoted to Calcitonin production,  it would be suitable
for producing  other  peptide  hormone  products in the future.  There can be no
assurance that there will be sufficient  acceptance of the Company's products in
the  marketplace  for  successful  commercialization.  See  "Risk  Factors - New
Production Facility."

         In addition to obtaining the FDA's  validation of the new facility,  it
is necessary to obtain FDA approval for human use of the salmon Calcitonin to be
produced in the facility.  This will require  various human and animal  studies.
The Company will then apply to the FDA for approval of the Company's  Calcitonin
for human use. The Company expects that the  requirements for such approval will
be abbreviated.  However,  there can be no assurance that such requirements will
be abbreviated or that the necessary  governmental approvals will be obtained as
projected.  Expanded consumer acceptance of pharmaceutical-grade  Calcitonin may
be dependent on development of a consumer  acceptable  delivery  system. A major
pharmaceutical  company received FDA approval during 1995 for the marketing of a
nasal spray delivery system for  Calcitonin,  which could enlarge the market for
Calcitonin.  The Company  and others are  conducting  research on oral  delivery
systems for Calcitonin. There can be no assurance that suitable delivery systems
will be developed or that governmental approval of such delivery systems will be
obtained.

         The Company is continuing its efforts to develop a Calcitonin  pill. In
December,   1995  and  January,   1996,  the  Company  successfully  tested  its
proprietary  Calcitonin  pill in Phase I clinical  trials in the United Kingdom.
These studies  indicated that the majority of those who received the pill showed
levels of the  hormone in blood  samples  taken  during the trial.  The  Company
believes that this is the first time significant blood levels of Calcitonin have
been observed in humans following oral administration of the hormone. Results of
a third Phase I trial showed that blood levels of the drug were  obtained in all
of the  recipients.  However,  there is no assurance  that these results will be
replicated  in  further  studies.  The  Company  has  recently  filed  a  patent
application for its oral  formulation  with the U.S. Patent and Trademark Office
and plans to file an  Investigational  New Drug (IND)  application with the FDA.
There can be no assurance that either  application will be approved as projected
or that the Company will be successful in marketing its products.

         The planned  activities  of the  Company  are all subject to  obtaining
adequate  financing.  There  can be no  assurance  that the  Company  will  have
sufficient  resources  to complete  the  preproduction  process,  to produce and
market its  products  and to carry on its other  projects.  See "Risk  Factors -
Absence of Operating Revenues and Liquidity; History of Losses; Auditors' Report
- - Going Concern Considerations."

         The  Company  is  currently  engaged  in  two  collaborative   research
programs. One, with Rutgers University College of Pharmacy,  seeks to develop an
oral drug delivery system for Calcitonin. The second collaboration, performed in
conjunction  with Yale  University,  is  investigating  novel  applications  for
certain  amidated  peptide  hormones,  including CGRP,  Calcitonin  gene-related
peptide.

         At  present,   the  Company  has  no  third  party  sponsored  research
agreements in effect. The Company is currently conducting discussions with major
pharmaceutical  companies regarding licensing and/or research agreements.  There
can be no  assurance  that  such  discussions  will  result in new  research  or
licensing agreements or that the Company will be able to obtain adequate funding
for  its  current  or  new   projects.   The  Company  is   dependent  on  large
pharmaceutical  companies,  having much greater resources than the Company,  for
revenues  from  sales of  product,  research  sponsorship,  joint  ventures  and
licensing  arrangements.  See "Risk Factors - Dependence on Large Pharmaceutical
Companies" and "Risk Factors - Risks of International Operations."

         The Company has established a multi-disciplinary research team to adapt
current  genetic  engineering  technologies  to the  development  of proprietary
products  and  processes.  The  Company,  at  June  1,  1996,  had 60  full-time
employees, including 25 research and development personnel and 24 pre-production
personnel.  10 employees have Ph.D.  degrees in the fields of molecular biology,
microbiology,  biochemistry,  pharmacology or organic  chemistry.  The Company's
employees have expertise in molecular biology, including DNA cloning, synthesis,
sequencing and expression; protein chemistry, including purification, amino acid
analysis,  synthesis  and  sequencing  proteins;  immunology,  including  tissue
culture,   monoclonal  and  polyclonal   antibody   production  and  immunoassay
development; chemical engineering; pharmaceutical production; quality assurance;
and quality control.  None of the Company's employees is covered by a collective
bargaining agreement.

         The Company was incorporated under the laws of the State of Delaware in
November  1980. Its executive  offices and laboratory  facilities are located at
110 Little Falls Road, Fairfield, New Jersey, 07004, and its telephone number is
(201)882-0860.


                              PLAN OF DISTRIBUTION

         The securities  covered by this  Prospectus  were registered as part of
the Company's  initial public offering and are issuable upon exercise of Class B
Warrants which were obtained upon exercise of Class A Warrants during 1991.

         Upon the  exercise of the Class B Warrants,  the Company  will pay D.H.
Blair & Co., Inc.  ("Blair"),  the  underwriter of the Company's  initial public
offering in 1987, a fee of 4% of the aggregate  exercise  price, of which 1% may
be reallowed to any dealer who solicited the exercise  (which may also be Blair)
if (i) the market  price of the  Company's  Common Stock on the date the Class B
Warrant is  exercised  is greater  than the then  exercise  price of the Class B
Warrants;  (ii) the exercise of the Class B Warrant was solicited by a member of
the NASD; (iii) the Class B Warrant is not held in a discretionary account; (iv)
disclosure  of  compensation  arrangements  was  made  both  at the  time of the
offering  and at the  time of  exercise  of the  Class B  Warrants;  and (v) the
solicitation  of exercise of the Class B Warrant  was not in  violation  of Rule
10b-6 promulgated  under the Securities  Exchange Act of 1934. Unless granted an
exemption by the Securities and Exchange  Commission from its Rule 10b-6,  Blair
and any soliciting broker-dealers will be prohibited from engaging in any market
making  activities  with regard to the issuer's  securities  for the period from
(two or nine) business days prior to any solicitation of the exercise of Class B
Warrants until the later of the termination of such solicitation activity or the
termination  (by waiver or  otherwise)  of any right  that Blair and  soliciting
broker-dealers  may have to receive a fee for the  exercise  of Class B Warrants
following such solicitation.  As a result,  Blair and soliciting  broker-dealers
may be unable to continue to provide a market for the issuer's securities during
certain periods while the Warrants are exercisable.


                            DESCRIPTION OF SECURITIES


         The  Securities  issuable  upon  exercise  of the Class B Warrants  are
shares of Common Stock.  The Common Stock  obtained upon exercise of the Class B
Warrants will be transferable immediately.

         The  Company  has listed the Common  Stock and Class B Warrants  on the
automated  quotation system of the National  Association of Securities  Dealers,
Inc.  ("NASDAQ").  The Company's Common Stock and Class B Warrants are listed on
the NASDAQ  National  Market System under the market symbols "UGNE" and "UGNEZ",
respectively.


Common Stock

         The  authorized  capital  stock of the Company  consists of  48,000,000
shares of Common Stock,  $.01 par value per share.  On June 7, 1996,  26,268,676
shares of Common Stock held by 615  stockholders of record were  outstanding and
10,985,366  additional  shares of Common Stock were  issuable  upon  exercise of
outstanding  stock options,  warrants and conversion of convertible  debentures.
See "Risk Factors -- Shares Eligible for Future Sales;  Outstanding  Convertible
Securities, Warrants and Options".

         The holders of validly  issued and  outstanding  shares of Common Stock
are  entitled  to one  vote  per  share  on all  matters  to be  voted  upon  by
stockholders including the election of directors.  There is no cumulative voting
with  respect to the  election of  directors,  which means that the holders of a
majority of the shares can elect all the  directors if they choose to do so, and
in such event,  the holders of the  remaining  shares would not be able to elect
any directors.

         The holders of Common Stock have no preemptive  or  conversion  rights,
nor are there any redemption rights provisions with respect to Common Stock. The
outstanding  shares are, and the shares subject to issuance  pursuant to options
and warrants when issued and paid for, will be fully paid and  nonassessable and
not subject to further call or assessment by the Company.  The holders of Common
Stock are entitled to such dividends, if any, as may be declared by the Board of
Directors in its discretion out of funds legally  available for that purpose and
to  participate  pro  rata in any  distribution  of the  Company's  assets  upon
liquidation.


Class B Warrants

         On June 7, 1996,  5,594,069 Class B Warrants held by 56 warrant holders
of record were outstanding.  Each Class B Warrant entitles the registered holder
to purchase 1.1992 shares of Common Stock at an exercise price of $4.1694 at any
time prior to 5:00 P.M.,  New York City Time,  on the earlier of August 11, 1996
or the  business  day  immediately  preceding  the date fixed by the Company for
redemption of the Class B Warrants.  The Class B Warrants are  redeemable by the
Company on thirty days written notice at a redemption price of $0.0417 per Class
B Warrant,  provided the average of the closing  prices of the Company's  Common
Stock  (or the  closing  bid  prices  if  closing  prices  are not  reported  or
available) for the thirty  consecutive  business days ending within fifteen days
of the notice of redemption exceeds $5.8372 per share. All Class B Warrants must
be redeemed if any are redeemed.

         The  issuance of Class B Warrants  is  governed by a warrant  agreement
(the  "Warrant  Agreement")  among the Company, Blair and Registrar and Transfer
Company,  Cranford,  New Jersey,  as warrant agent, and are evidenced by Class B
Warrant  certificates  in  registered  form.  The Class B Warrants  provide  for
adjustment  of the  exercise  price  and for a change  in the  number  of shares
issuable upon  exercise to protect  holders  against  dilution in the event of a
stock dividend, stock split, combination or reclassification of the Common Stock
or upon  issuance  of shares of Common  Stock at prices  lower  than the Class B
Warrant  exercise  price then in effect other than  issuances  upon  exercise of
existing options and options granted to employees,  directors and consultants to
the Company.

         The Class B Warrants  may be  exercised  upon  surrender of the Class B
Warrant  certificate on or prior to the expiration  date (or earlier  redemption
date) of such Class B Warrants at the offices of Registrar and Transfer Company,
the warrant  agent,  with the form of "Election to Purchase" on the reverse side
of the  Class  B  Warrant  certificate  completed  and  executed  as  indicated,
accompanied  by payment of the full  exercise  price (by certified or bank check

Item 15.  Indemnification of Directors and Officers

         Article VI of the Company's  By-Laws  requires the Company to indemnify
each of its  directors  and  officers to the extent  permitted  by the  Delaware
General  Corporation  Law (the "DGCL").  Section 145 of the DGCL provides that a
corporation may indemnify any person, including any officer or director, who was
or is a party or who is threatened to be made a party to any threatened, pending
or completed action, suit or proceeding, whether civil, criminal, administrative
or investigative  (other than an action by or in the right of the  corporation),
by reason of the fact that he is or was a director,  officer,  employee or agent
of the  corporation or is or was serving at the request of the  corporation as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees), judgments, fines and amounts paid in settlement,  actually and reasonably
incurred by such person, if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the  corporation  and,
with respect to any criminal  action or proceeding,  had no reasonable  cause to
believe his conduct was unlawful.  In any threatened pending or completed action
by or in the right of the  corporation,  a  corporation  also may  indemnify any
director,  officer, employee or agent for costs actually and reasonably incurred
by him in connection  with the defense or settlement of the action,  if he acted
in good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the corporation;  however, no indemnification may be made with
respect to any claim,  issue or matter as to which such  person  shall have been
adjudged to be liable to the  corporation,  unless and only to the extent that a
court shall determine that such indemnity is proper. Where a director,  officer,
employee or agent is successful on the merits or otherwise in the defense of any
action  referred to above,  the corporation is required to indemnify such person
against  the  expenses  (including  attorneys'  fees)  actually  and  reasonably
incurred.

         The Company's Certificate of Incorporation  provides that its directors
shall not be liable for monetary  damages to the Company or its stockholders for
breach of the directors' fiduciary duty as directors.  However, each director is
subject to liability for breach of the director's duty of loyalty to the Company
or its  stockholders,  for acts or  omissions  not in good  faith  or  involving
intentional  misconduct  or knowing  violations  of law, for actions  leading to
improper  personal  benefit to the  director,  and for payment of  dividends  or
approval of stock  repurchases or  redemptions  that are unlawful under Delaware
law.

Item 17.  Undertakings

         The undersigned Registrant hereby undertakes:

         (1)      To file,  during any period in which offers or sales are being
                  made,  a   post-effective   amendment   to  the   Registration
                  Statement:

                  (i)      To  include  any   prospectus   required  by  section
                           10(a)(3) of the Securities Act of 1933;

                  (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 set forth in the registration  statement.
                           Notwithstanding   the  foregoing,   any  increase  or
                           decrease  in volume  of  securities  offered  (if the
                           total dollar value of  securities  offered  would not
                           exceed that which was  registered)  and any deviation
                           from  the low or high  end of the  estimated  maximum
                           offering  range  may  be  reflected  in the  form  of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) if, in the  aggregate,  the  changes in volume
                           and price  represent no more than a 20% change in the
                           maximum  aggregate  offering  price  set forth in the
                           "Calculation  of  Registration   Fee"  table  in  the
                           effective registration statement.

                  (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 paragraphs (a)(1)(i) and (a)(1)(ii) of
                  this  section do not apply if the  information  required to be
                  included in a post-effective  amendment by those paragraphs is
                  contained in periodic  reports  filed with or furnished to the
                  Commission by the Registrant pursuant to section 13 or section
                  15(d)  of  the  Securities  Exchange  Act  of  1934  that  are
                  incorporated by reference in the registration statement.

         (2)      That, for the purpose of determining  any liability  under the
                  Securities  Act of 1933,  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.

         (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.

         The  undersigned  Registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
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.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933  ("Act") may be  permitted  to  directors,  officers or  controlling
persons of the Registrant by charter,  by-law,  contract,  statute 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 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 Act and will
be governed by the final adjudication of such issue.

                         CONSENT OF INDEPENDENT AUDITORS



The Board of Directors
Unigene Laboratories, Inc.:


We consent to the incorporation by reference in this  Registration  Statement on
Form S-3 of Unigene  Laboratories,  Inc.  of our report  dated  March 22,  1996,
relating to the balance sheets of Unigene Laboratories,  Inc. as of December 31,
1995 and 1994 and the related  statements of operations,  stockholders'  equity,
and cash flows for each of the years in the three-year period ended December 31,
1995 which report appears in the December 31, 1995 annual report on Form 10-K of
Unigene Laboratories,  Inc. which is incorporated herein by reference and to the
reference to our firm under the heading "Experts" in the Prospectus.

   
Our report dated March 22, 1996 contains an  explanatory  paragraph  that states
that the Company has suffered  recurring  losses from  operations  and has a net
working capital  deficiency,  which raise substantial doubt about its ability to
continue  as a going  concern.  The  financial  statements  do not  include  any
adjustment that might result from the outcome of this uncertainty.
