Prospectus                                                 Subject to Completion
                                                             November 4, 1998


                           UNIGENE LABORATORIES, INC.


                                  Common Stock
                           (par value $.01 per share)

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

         This  Prospectus  relates  to the resale of up to  3,852,500  shares of
common  stock,  par value  $.01 per  share  (the  "Common  Stock"),  of  Unigene
Laboratories,  Inc., a Delaware  corporation  (the  "Company"),  issuable by the
Company to the Tail Wind Fund,  Ltd.  (the "Selling  Shareholder")  (i) upon the
conversion of $4 million in aggregate  principal  amount of certain  convertible
debentures  described  herein  (the  "Debentures")  issued by the  Company  in a
private  placement  completed  in June 1998,  (ii) as payment of interest on the
Debentures,  and (iii) upon exercise of certain warrants issuable by the Company
upon conversion or redemption of the Debentures.  Beginning January 1, 1999, the
Debentures  are  convertible  into (i) Common Stock at a  conversion  price (the
"Conversion Price") equal to the lower of (a) 110% of the average of the closing
bid prices of the  Common  Stock on the Nasdaq  Stock  Market  during the fourth
quarter of 1998 (the "Cap Price") and (b) the average of the four lowest closing
bid prices of the Common  Stock  during the 18 trading days prior to the date of
conversion (the "Market Price") and (ii) warrants,  expiring five years from the
date of issuance,  to purchase a number of shares of Common Stock equal to 4% of
the number of shares  issuable upon  conversion of the Debentures at an exercise
price equal to 125% of the Conversion Price. Subject to certain adjustments,  up
to 15% of the original principal amount of Debentures may be converted per month
on a  non-cumulative  basis.  In no event  will the  Company  issue more than an
aggregate of the 3,852,500  shares of Comon Stock upon  conversion of all of the
Debentures,  upon exercise of all warrants  issued upon conversion or redemption
of  Debentures,  and as payment of  interest  on the  Debentures.  See  "Selling
Shareholder".  All of the shares  offered hereby will be offered and sold by the
Selling Shareholder.  The Company will not receive any proceeds from the sale of
the shares of Common Stock offered hereby.

         The Common  Stock  trades on the Nasdaq  Stock  Market under the symbol
UGNE. On November 2, 1998 the last sale price of the Common  Stock,  as reported
on the  Nasdaq  Stock  Market,  was  $1.50 per  share.  The  Debentures  are not
convertible until January 1, 1999. Accordingly, none of the Common Stock offered
hereby  has been  issued.  However,  assuming  conversion  of all $4  million in
aggregate principal amount of Debentures on November 3, 1998 at the Market Price
on such date, such Debentures  would be convertible into (i) 3,367,003 shares of
Common Stock and (ii) warrants to purchase 134,680 shares of Common Stock.
    
<PAGE>

         The  Common  Stock  may be  offered  from  time to time by the  Selling
Shareholder to or through brokers,  dealers or other agents or directly to other
purchasers  in  one  or  more  market  transactions,  in  one  or  more  private
transactions  or in a  combination  of such  methods  of sale,  at  prices  then
prevailing,  at prices  related to such  prices,  or at  negotiated  prices.  In
effecting  sales,  brokers,  dealers  or other  agents  engaged  by the  Selling
Shareholder  may arrange for other  brokers,  dealers or agents to  participate.
Such  brokers,   dealers  or  agents  may  receive  commissions,   discounts  or
concessions  from the  Selling  Shareholder  in amounts to be  negotiated.  Such
brokers or dealers and any other participating  brokers or dealers may be deemed
to be  "underwriters"  within the  meaning  of the  Securities  Act of 1933,  as
amended  (the  "Securities  Act"),  and  any  such  commissions,   discounts  or
concessions may be deemed to be underwriting  discounts or commissions under the
Securities Act. The Company has advised the Selling Shareholder that (i) it must
comply with applicable prospectus delivery requirements under the Securities Act
in connection with any short sales and (ii) the anti-manipulative  provisions of
Regulation M under the Securities Exchange Act of 1934, as amended, may apply to
its sales in the market.

         All costs, expenses and fees in connection with the registration of the
Common Stock will be borne by the Company,  except  commissions,  discounts  and
transfer  taxes, if any,  attributable  to the sales of the Common Stock,  which
will be borne by the Selling Shareholder.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         Certain statements in this Prospectus under the captions "Risk Factors"
and "The Company" constitute "forward-looking  statements" within the meaning of
the Private  Securities  Litigation  Reform Act of 1995 (the "Reform Act"). Such
forward-looking  statements  involve known and unknown risks,  uncertainties and

financial  condition of the Company,  competition,  the Company's  dependence on
other  companies  to  commercialize,  manufacture  and sell  products  using the
Company's  technologies,  the uncertainty of results of preclinical and clinical
testing,  the risk of product liability and liability for human clinical trials,
the Company's dependence on patents and other proprietary rights,  dependence on
key management officials, the availability and cost of capital, the availability
of qualified personnel,  changes in, or the failure to comply with, governmental

<PAGE>
                                  RISK FACTORS

         Prospective  investors should consider  carefully the following factors
concerning the Company and its business before purchasing  securities offered by
this   Prospectus.    Certain   statements   under   this   caption   constitute
"forward-looking  statements"  under the Reform Act. See "Special Note Regarding
Forward-Looking Statements."

         History of Losses; Auditors' Report - Going Concern Considerations. The
Company has  incurred  annual  operating  losses since its  inception  and, as a
result,  at June 30,  1998,  had an  accumulated  deficit  of $58  million.  The
auditors'  report for the fiscal  year ended  December  31,  1997  contained  an
explanatory  paragraph indicating there is substantial doubt about the Company's
ability to continue as a going concern.

         Management believes that the Company has sufficient financial resources
to sustain its  operations  at the current level into the first quarter of 1999.
The Company will require additional funds to ensure continued  operations beyond
that time.  Although there can be no assurance,  the Company  expects to achieve
milestones  specified under the Warner-Lambert  agreement,  which will result in
payments to the Company. See "The Company." However, the timing of such payments
is uncertain  and the Company may have to rely on outside  sources for financing
to sustain the  Company's  operations.  There is no assurance as to the terms on
which such  additional  funds would be available  or that in such  circumstances
sufficient  funds could be obtained.  Management  believes that  satisfying  the
Company's   long-term   liquidity   requirements  will  require  the  successful
commercialization  of the product licensed to Warner-Lambert or one of its other
Calcitonin  products.  There can be no assurance  that there will be  sufficient
acceptance  of  the  Company's   products  in  the  marketplace  for  successful
commercialization.

         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  that  may  be  encountered  by
enterprises in a stage of transition,  some of which may be beyond the Company's
control.
<PAGE>
         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
comparable  regulatory  authorities  outside  of the  United  States.  See "Risk
Factors - Government  Regulation."  There can be no assurance that the necessary
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 likely will 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 Calcitonin pharmaceutical products will
depend  on the  development  of a  consumer-accepted  delivery  system.  A major
pharmaceutical  company  received  FDA  approval in 1995 for the  marketing of a
nasal spray delivery system for  Calcitonin,  which has enlarged the U.S. market
for Calcitonin.  The Company, in collaboration with  Warner-Lambert,  as well as
other companies are conducting research on oral delivery systems for Calcitonin.
There can be no assurance that the Company will develop a suitable oral delivery
system or that  governmental  approval of 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. There are synthetic salmon Calcitonin products as well
as non-Calcitonin  products currently being marketed for osteoporosis  treatment
or in development that will compete with the Company's 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 - History of Losses; Auditors' Report - Going Concern Considerations."

         Production  Facility.  The Company has constructed a facility  intended
for  the  production  of  pharmaceutical-grade   Calcitonin  and  other  peptide
hormones.  The Company is the lessee of this facility under a 10-year lease that
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
approval of the  facility by various  regulatory  agencies,  including  the FDA,
which would allow it to manufacture Calcitonin for human pharmaceutical use. The
facility is producing  Calcitonin in accordance with current Good  Manufacturing
Practice ("cGMP") regulations,  but there is no assurance that the facility will
be  approved  by such  agencies.  See "Risk  Factors -  Government  Regulation."
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 produce and market
its products from the facility. In addition, the successful commercialization of
an oral  Calcitonin  product  will  require  the  Company  to  incur  additional
expenditures  to expand or upgrade the  Company's  manufacturing  operations  to
satisfy its supply obligations under the Warner-Lambert  license agreement.  See
"Risk Factors - Dependence on Large Pharmaceutical  Companies." Neither the cost
or timing of such capital expenditures are determinable at this time.
<PAGE>
         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.  In July 1997,  the Company  entered  into an agreement
under which it granted to the Parke-Davis  division of Warner-Lambert  Company a
worldwide license to use the Company's oral Calcitonin  technology.  The Company
has retained the right to license the use of its technologies for injectable and
nasal  formulations  of Calcitonin on a worldwide  basis.  There is no assurance
that the Company will achieve the milestones under the Warner-Lambert  agreement
or that the Company will be successful in its efforts to enter into new research
or  licensing  agreements  or other  revenue  producing  arrangements.  See "The
Company."

         In June 1995,  the  Company  entered  into a joint  venture  agreement,
effective as of March 1996, with the Qingdao General  Pharmaceutical Company and
its Huanghai  factory for the  production  and marketing of injectable and nasal
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 nonproprietary aspects of the Company's
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
annual  royalties  based  upon  sales of the end  product.  This  joint  venture
contributed  $300,000 to 1996 revenues.  It is uncertain  whether any additional
revenues will be recognized or received in connection with this 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 regulation or approval 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 - Calcitonin  for the  treatment of  osteoporosis.
The market for the 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. Major
competitors in the field of osteoporosis  treatment include  Novartis,  American
Home Products,  Merck and Eli Lilly.  There can be no assurance that others will
not develop  processes or products which are superior to, or otherwise  preclude
the commercial utilization of, processes or products developed by the Company.

         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 would have sufficient  resources to defend against or
satisfy any such claims.  Although the Company has  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.
<PAGE>
         Patents and Proprietary Technology.  The Company has filed applications
for U.S. patents  relating to proprietary  amidation,  bacterial  expression and
immunization processes and to oral formulations for Calcitonin and other peptide
hormones  invented in the course of its research.  To date, the following  three
patents have issued:  Immunization By Immunogenic Implant, a process patent, and
two patents  related to the  Alpha-Amidation  Enzyme,  both  process and product
patents.  In addition,  the Company has  received a Notice of Allowance  for its
patent  application  covering  the oral  delivery  of salmon  Calcitonin.  Other
applications  are pending.  Filings  related to the amidation  process have also
been made in selected  foreign  countries and numerous 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  applications  to issue as patents  could
have a material adverse effect upon the Company's business.  Although one patent
application currently is the subject of an interference proceeding,  the Company
does not believe that an adverse ruling would have a material  adverse effect on
the business of the Company or its  prospects.  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  by the Company 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,   development  and
production  activities  of the  Company  and  its  sponsors,  collaborators  and
licensees, and the processes and products which may be developed by them and the
Company's production facility, are subject to significant regulation by numerous
federal,  state,  local and  foreign  governmental  authorities.  In addition to
obtaining  the  approval  of the  production  facility  by  the  FDA  and  other
regulatory agencies,  it is necessary to obtain the approval by such agencies of
the  Calcitonin  to be produced in the facility  for human use.  The  regulatory
approval process for a pharmaceutical product requires substantial resources and
may take a number of years.  There can be no assurance that regulatory  approval
will  be  obtained  for the  production  facility  or for  any of the  Company's
products  or that  such  approvals  will be  obtained  in a timely  manner.  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, and receive revenue from milestone payments,  product sales
or royalties.  Furthermore,  the extent of any adverse  governmental  regulation
that may arise from  future  legislative  and  administrative  action  cannot be
predicted.
<PAGE>
         The Company's production facility may, from time to time, be audited by
the  FDA or  other  regulatory  agencies  to  ensure  that  it is  operating  in
compliance with cGMP guidelines  which require that the production  operation be
conducted in strict  compliance with, among other things,  the Company's written
protocols  for  reagent  qualification,   process  execution,   data  recording,
instrument  calibration and quality  monitoring.  Such agencies are empowered to
suspend  production  operations  and/or  product  sales  if,  in their  opinion,
significant and/or repeated deviations from these protocols have occurred.  Such
a  suspension  could  have a material  adverse  impact on the  Company's  future
operations.

         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
Levy nor Dr. Ronald 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.  In addition to the  3,852,500  shares of Common Stock to
which this  Prospectus  relates,  as of July 31, 1998,  there are  approximately
214,000  shares  of  Common  Stock  that are  issuable  upon  conversion  of the
Company's outstanding 10% convertible  debentures;  approximately 449,000 shares
of Common Stock  issuable  upon  conversion of the  Company's  outstanding  9.5%
convertible debentures;  approximately 4,919,000 shares of Common Stock issuable
upon exercise of outstanding  warrants at exercise prices ranging from $1.375 to
$3.50 per share;  and  approximately  1,916,000  shares of Common Stock issuable
upon exercise of options  exercisable  at prices ranging from $1.19 to $4.25 per
share.  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 effect that market sales of the Common
Stock  issuable  upon  the  conversion  of such  convertible  securities  or the
exercise of such options or warrants will have on the market price of the Common
Stock  prevailing  from time to time,  although it is  possible  that sales of a
large number of securities would depress the market price. In addition,  holders
of such  convertible  securities,  including  the  Debentures  and the  warrants
issuable  upon  conversion  thereof,  may engage in short sales of Common Stock,
which may have the effect of  depressing  the market  price.  If the minimum bid
price for the Common  Stock  falls below $1 per share,  the Common  Stock of the
Company no longer would continue to meet all of the maintenance requirements for
trading on the Nasdaq Nationl  Market and could be delisted,  which could have a
material  adverse effect on the quality of the market for the Common Stock.  The
Company also cannot  predict the adverse  effect,  if any, that the existence of
such convertible  securities,  options and warrants would 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 or
<PAGE>
existing products or procedures,  proposed government regulations,  developments
or disputes relating to agreements,  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  11% of the outstanding  Common
Stock (assuming that outstanding  convertible  securities,  warrants and options
held by others are not converted or exercised) and, thus,  effectively  they 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
and the minimum bid price for the Common Stock must be $1 per share.  As of June
30, 1998 the amount of the Company's net tangible assets was approximately  $5.9
million and on  November  2, 1998 the closing bid price of the Common  Stock was
$1.50.  However,  if the Company in the future is unable to maintain  compliance
with the Nasdaq National Market listing requirements,  the Common Stock could be
removed from trading on the Nasdaq National Market. If the Company 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
holders of the Common Stock to resell the securities.

                                   THE COMPANY

         Unigene  Laboratories,  Inc.  is a  biopharmaceutical  company  that is
focusing  on the  development  of  Calcitonin  products  for  the  treatment  of
osteoporosis. The Company is currently producing pharmaceutical grade Calcitonin
in  accordance  with  current  Good  Manufacturing  Practice  guidelines  at its
facility in Boonton, New Jersey,  developing production technology improvements,
developing novel Calcitonin  formulations and associated analytical methods, and
registering its injectable Calcitonin product in Europe.
<PAGE>
         The Company's business 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 on third party sales and/or direct sales
of  bulk or  finished  products.  Generally,  the  Company  seeks  sponsors  and
licensees to provide  research funding and assume  responsibility  for obtaining
appropriate  regulatory  approvals,  clinical testing, and marketing of products
derived from the Company's research  activities.  However, in certain cases, the
Company may retain  responsibility  for clinical  testing and for  obtaining the
required  regulatory  approvals.  To date,  the  Company has focused its efforts
primarily on the manufacture  of, and the development of novel delivery  systems
for, salmon Calcitonin.

         In July 1997,  the Company  entered  into an  agreement  under which it
granted  to the  Parke-Davis  division  of  Warner-Lambert  Company a  worldwide
license to use the Company's oral Calcitonin  technology.  Upon execution of the
agreement,  the Company  received  payments of $6  million,  consisting  of a $3
million  license  fee  and a $3  million  equity  investment  by  Warner-Lambert
(695,066  shares of the  Company's  Common  Stock were  purchased  at a price of
approximately  $4.32 per share).  Under the terms of the license agreement,  the
Company is eligible to receive up to an  additional  $48.5  million in milestone
payments if specified milestones are achieved. The first of these milestones was
achieved in February  1998,  resulting in a payment to the Company of $2 million
and other  milestones  were achieved in August and September 1998 resulting in a
payment of $3 million in September  1998. An  additional  $10.5 million would be
received if other  milestones are achieved prior to the  commencement of Phase I
clinical  studies in the U.S.  Early-stage  milestones  primarily  relate to the
product's  performance  characteristics,  while the latter-stage  milestones are
primarily  related  to  regulatory  filings  and  approvals.  If the  product is
successfully  commercialized,  the Company also would  receive  revenue from the
sale of raw  material  to  Warner-Lambert  and  royalties  on  product  sales by
Warner-Lambert  and its  affiliates.  The  Company  is  actively  seeking  other
licensing and/or supply agreements with pharmaceutical  companies for injectable
and nasal forms of Calcitonin.
 
         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
(973) 882-0860.
 
Year 2000

         The Company has  established a Year 2000 taskforce that will review all
of the Company's  internal computer systems for Year 2000 compliance,  including
workstations,  its accounting  system,  and control systems for equipment in the
Company's manufacturing and laboratory facilities.  The Company expects that the
taskforce  will  commence its  compliance  review in November  1998 and that the
review will be completed  during the first quarter of 1999.  After the review is
completed,   the  taskforce  will  determine  how  to  address  any  remediation
necessary. The Company intentds to repair or replace any noncompliant systems in
a timely manner so that the business of the Company will not be interrupted.

         Because most of the principal hardware and software used by the Company
(including its accounting system and most of the equipment control systems) were
acquired by the Company within the last several years,  the Company expects that
most of its systems will be Year 2000  compliant.  However,  until the taskforce
completes  its  review,  the  Company  will not be able to  assess  the level of
compliance or make an accurate estimate of the costs of any remediation.

<PAGE>

         The Company has no material  relationships  with third party  suppliers
and its obligations to its sole material customer, Warner-Lambert,  would not be
significantly affected by Year 2000 noncompliance on the part of Warner-Lambert.
However,  the  loss  of the  electricity  supply  to the  Company's  laboratory,
production  and  administratiave  facilities  would  cause a shut  down of those
facilities  which,  depending  on the  duration  of the  shut  down,  may have a
material  adverse  impact on the Company's  business.  In addition,  the loss of
telecommunications  services and banking services would, as is the case with all
businesses, adversely affect the Company.


                              SELLING SHAREHOLDER 

         In June 1998 the Company  completed a private  placement  (the "Private
Placement") in which it sold to the Selling  Shareholder $4 million in aggregate
principal  amount  of 5%  convertible  debentures  due  December  31,  2001 (the
"Debentures").  Interest on the  Debentures is payable in cash or, at the option
of the Company,  in Common Stock.  Beginning January 1, 1999, the Debentures are
convertible into (i) Common Stock at a conversion price (the "Conversion Price")
equal to the lower of (a) 110% of the  average of the  closing bid prices of the
Common Stock on the Nasdaq Stock Market  during the fourth  quarter of 1998 (the
"Cap  Price") and (b) the  average of the four lowest  closing bid prices of the
Common  Stock during the 18 trading  days prior to the date of  conversion  (the
"Market  Price")  and  (ii)  warrants,  expiring  five  years  from  the date of
issuance,  to  purchase  a number of shares of Common  Stock  equal to 4% of the
number of shares issuable upon conversion of the Debentures at an exercise price
equal  to 125% of the  Conversion  Price.  Up to 15% of the  original  principal
amount of the Debentures may be converted per month on a  non-cumulative  basis;
provided,  however, that if the Market Price is greater than or equal to 120% of
the Cap Price on the last  conversion  date in any month,  then up to 20% of the
original  principal  amount  may be  converted  in  such  month.  Under  certain
circumstances,  the  limitation  on  conversion  amounts  may be  waived  by the
Company. After July 31, 1999, all of the Debentures will be fully convertible.

         The Debentures by their terms provide that  conversion of Debentures or
payment of interest  thereon in Common Stock is not  permitted,  and a holder of
Debentures  may not submit them for  conversion,  if such  conversion or payment
would result in the holder  owning (as  determined  pursuant to Rule 13d-3 under
the Exchange Act) more than 4.99% of all issued and outstanding Common Stock.

         If a Debenture holder submits a Debenture for conversion and the Market
Price is less than or equal to $1.1156, the Company at its option may redeem the
Debenture  in  consideration  of (i) an  amount  equal to the  principal  amount
thereof  plus a  premium  of 12% per year  from the  date of  issuance  and (ii)
warrants, expiring five years from the date of issuance, to purchase a number of
shares of Common Stock equal to 25% of the number of shares that would have been
issuable upon  conversion of the Debenture at an exercise price equal to 135% of
the Conversion Price at the time of redemption.
 
         In no event  will the  Company  issue  more  than an  aggregate  of the
3,852,500  shares of Common  Stock  offered  hereby  (the  "Share  Limit")  upon
conversion of all of the  Debentures,  upon exercise of all warrants issued upon
conversion  or  redemption  of  Debentures,  and as payment of  interest  on the
Debentures.  If conversion of any  Debentures or exercise of any warrants  would
require the issuance of shares in excess of the Share Limit,  the Company  will,
as the case  may be,  redeem  such  Debentures  at a price  equal to 120% of the
principal amount thereof or pay in cash the difference  between the market price
and exercise  price of the number of shares that would have been  issuable  upon
exercise of such warrants but for the Share Limit.
<PAGE>

         In  connection  with the  Private  Placement,  the  Company  agreed  to
register for resale  under the  Securities  Act a total of  3,852,500  shares of
Common Stock which  represents the Share Limit  issuable (i) upon  conversion of
the Debentures,  (ii) as payment of interest on the  Debentures,  and (iii) upon
exercise of the warrants  issuable by the Company upon  conversion or redemption
of the Debentures,  and to keep such registration statement effective until such
shares  have  been  sold  or  until  such  time  as  they  become  eligible  for
distribution  pursuant to Rule 144(k) under the Securities  Act. 
   
         The  Selling  Shareholder  has not had any  position,  office  or other
material  relationship  with the Company or any of its  predecessors  within the
past three  years.  The  following  table sets forth with respect to the Selling
Shareholder:   name,  number  of  shares  of  Common  Stock  beneficially  owned
(including  shares  issuable  upon the  exercise  of  outstanding  warrants  and
Debentures), number of shares of Common Stock being offered and number of shares
of Common Stock to be held  following the offering,  assuming the sale of all of
the shares of Common Stock offered hereby. The Debentures by their terms are not
convertible  until January 1, 1999, and the following  information  assumes that
the only  securities  of the  Company  owned by the  Selling  Shareholder  as of
January 1, 1999 will be $4 million in aggregate  principal amount of Debentures.
The Company  has been  advised by the  Selling  Shareholder  that as of the date
hereof it does not own any securities of the Company other than the  Debentures.
The Company may amend or supplement  this Prospectus from time to time to update
the  disclosure set forth herein or to disclose the names and  relationships  to
the Company of additional  Selling  Shareholders  who are  transferees of Common
Stock from the Selling  Shareholder named below and the holdings of Common Stock
of such additional Selling Shareholders.

                              PLAN OF DISTRIBUTION

         The purpose of this Prospectus is to permit the Selling Shareholder, if
it  desires,  to  dispose  of some or all of the  Common  Stock  covered by this
Prospectus  at such times and at such  prices as it  chooses.  Whether  sales of
shares will be made,  and the timing and amount of any sale made,  is within the
sole discretion of the Selling Shareholder.

         The Common  Stock  covered by this  Prospectus  may be offered for sale
from time to time by the  Selling  Shareholder  to or  through  underwriters  or
directly  to  other   purchasers  or  through  agents  in  one  or  more  market
transactions,  in one or more private  transactions  or in a combination of such
methods of sale, at prices then prevailing,  at prices related to such prices or
at  negotiated  prices.  Such  methods  of  distribution  may  include,  without
limitation: (a) a block trade in which the broker-dealer so engaged will attempt
to sell the Common Stock as agent,  but may position and resell a portion of the
block  as  a  principal  to  facilitate  the  transaction;  (b)  purchases  by a
broker-dealer  as a  principal  and  resale  by such  broker-dealer  for its own
account pursuant to this  Prospectus;  (c) ordinary  brokerage  transactions and
transactions  in which the  broker  solicits  purchasers;  and (d)  face-to-face
transactions  between  sellers and purchasers  without a broker or dealer.  This
Prospectus  may be  amended  or  supplemented  from time to time to  describe  a
specific plan of distribution.

         In connection with distributions of the Common Stock or otherwise,  the
Selling  Shareholder may enter into hedging  transactions with broker-dealers or
other   financial   institutions.   In   connection   with  such   transactions,
broker-dealers  or other  financial  institutions  may engage in short  sales of
Common  Stock in the course of hedging the  positions  they assume with  Selling
Shareholder.  The  Selling  Shareholder  may also sell  Common  Stock  short and
redeliver the shares to close out such short positions.  The Selling Shareholder
may also enter into options or other  transactions with  broker-dealers or other
financial  institutions  which  require the  delivery to such  broker-dealer  or
financial  institution  of the Common Stock offered  hereby,  which Common Stock
such  broker-dealer or other financial  institutions may resell pursuant to this
Prospectus (as amended or supplemented to reflect such transaction). The Selling
Shareholder also may pledge the shares  registered  hereunder to a broker-dealer
<PAGE>
or other financial  institution and, upon a default, such broker-dealer or other
financial  institution  may effect sales of the pledged Common Stock pursuant to
this  Prospectus (as  supplemented or amended to reflect such  transaction).  In
addition,  any Common Stock covered by this  Prospectus  that qualifies for sale
pursuant to Rule 144 under the  Securities Act may be sold under Rule 144 rather
than pursuant to this Prospectus.

         Brokers,  dealers or agents  may  receive  compensation  in the form of
commissions, discounts or concessions from the Selling Shareholder in amounts to
be negotiated in connection with sales pursuant hereto.  Such brokers or dealers
and  any  other   participating   brokers  or  dealers   may  be  deemed  to  be
"underwriters" within the meaning of the Securities Act, in connection with such
sales  and any such  commission,  discount  or  concession  may be  deemed to be
underwriting discounts or commissions under the Securities Act.

         All costs, expenses and fees in connection with the registration of the
Common Stock will be borne by the Company.  Commissions,  discounts and transfer
taxes,  if any,  attributable  to the sales of the Common Stock will be borne by
the Selling  Shareholder.  The Selling  Shareholder  has agreed to indemnify the
Company  or any  underwriter,  as the case may be,  and any of their  respective
affiliates,  directors,  officers,  employees,  agents and controlling  persons,
against certain  liabilities in connection with the offering of the Common Stock
pursuant to this Prospectus,  including liabilities arising under the Securities
Act. In addition, the Company has agreed to indemnify the Selling Shareholder or
any  underwriter,  as the case may be, and any of their  respective  affiliates,
directors,  officers, employees, agents and controlling persons, against certain
liabilities in connection with the offering of the Common Stock pursuant to this
Prospectus, including liabilities arising under the Securities Act.

         The  Company  has agreed to supply the  Selling  Shareholder  with such
number of copies of this  Prospectus as it may reasonably  request.  The Selling
Shareholders  will in all cases be responsible for complying with the prospectus
delivery  requirements  of Section  5(b)(2) of the  Securities Act in connection
with the offering and sale of the Common Stock, including any short sales.

                                  LEGAL MATTERS

         Certain  legal  matters in  connection  with the shares of Common Stock
offered  hereby are being  passed upon for the  Company by  Covington & Burling,
Washington, D.C.

                                     EXPERTS

         The audited financial statements of the Company as of December 31, 1997
and 1996, and for each of the years in the three-year  period ended December 31,
1997,  incorporated by reference in this  Prospectus  have been  incorporated by
reference  herein  in  reliance  upon  the  report  of KPMG  Peat  Marwick  LLP,
independent certified public accountants,  incorporated by reference herein, and
upon the  authority  of said firm as experts in  accounting  and  auditing.  The
report of KMPG Peat Marwick LLP covering the 1997 financial  statements contains
an explanatory  paragraph that states that the Company's  recurring  losses from
operations raises substantial doubt about the Company's ability to continue as a
going concern. The financial statements do not include any adjustment that might
result from the outcome of that uncertainty.

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.  Section 145 also 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 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) 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 he reasonably  believed to be
in or not  opposed to the best  interests  of the  corporation,  except  that no
<PAGE>
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 of  competent  jurisdiction  shall
determine  that such  indemnity  is  proper.  To the extent  that a director  or
officer is  successful  on the merits or  otherwise in the defense of any action
referred to above,  the corporation is required under the DGCL to indemnify such
person  against  expenses  (including  attorneys'  fees) actually and reasonably
incurred in connection therewith.

         The Company's  Certificate of  Incorporation  provides that no director
shall be liable to the  Company or its  stockholders  for  monetary  damages for
breach of his  fiduciary  duty as a director,  except for  liability for (i) any
breach of the  director's  duty of loyalty to the  Company or its  stockholders,
(ii) acts or omissions not in good faith or involving intentional  misconduct or
knowing  violation of law, (iii) any transaction from which the director derived
an improper personal benefit,  or (iv) 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  this   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.
<PAGE>
                           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 (1)(i) and (1)(ii) do not
                  apply  if the  registration  statement  is on Form S-3 or Form
                  S-8,  and  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  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 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.

We consent to the incorporation by reference in this  Registration  Statement on
Form S-3 of Unigene  Laboratories,  Inc. of our report dated  February 20, 1998,
relating to the balance sheets of Unigene Laboratories,  Inc. as of December 31,

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 February 20, 1998 contains an explanatory paragraph that states
that the Company has  suffered  recurring  losses from  operations  which raises
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.
