                           (par value $.01 per share)

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

                  This  Prospectus  relates to the  resale of 490,000  shares of

sold by the Selling Shareholders. The Company will not receive any proceeds from
the sale of the shares of Common Stock offered hereby.

                  The Common Stock is listed on the Nasdaq National Market under

prevailing,  at prices  related to such  prices,  or at  negotiated  prices.  In
effecting  sales,  brokers,  dealers  or other  agents  engaged  by the  Selling
Shareholders  may arrange for other brokers,  dealers or agents to  participate.
Such  brokers,   dealers  or  agents  may  receive  commissions,   discounts  or
concessions  from the Selling  Shareholders  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

registration  of the  Common  Stock will be borne by the  Company.  Commissions,

                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
other factors that may cause the actual  results,  performance  or activities of
the Company,  or industry  results,  to be materially  different from any future
results,  performance or activities expressed or implied by such forward-looking
statements.  Such factors include: general economic and business conditions, the
financial  condition of the Company,  competition,  the Company's  dependence on
other  companies  to  commercialize,  manufacture  and sell  products  using the
<PAGE>
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
regulations,  the  failure  to  obtain  regulatory  approvals  of the  Company's
products and other factors discussed in this Prospectus. See "Risk Factors."

                                  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 September 30, 1997, had an accumulated deficit of $51.5 million.  The
auditors'  report for the fiscal  year ended  December  31,  1996  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  through the first  quarter of
1998. The Company will require  additional funds to ensure continued  operations
beyond that time.  In July 1997,  the Company  entered into a license  agreement
with  Warner-Lambert  Company for oral Calcitonin  pursuant to which the Company
received payments of $6 million,  consisting of a $3 million initial license fee
and a $3 million  equity  investment by  Warner-Lambert.  Under the terms of the
license  agreement,  the Company is eligible  receive up to an additional  $48.5
million in  milestone  payments if specified  milestones  are  achieved.  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.  See "The Company."  Management  currently
believes that the various milestones can be achieved on a timely basis,  thereby
providing the necessary  funds for continued  operations and precluding the need
for outside financing of the Company's operations in the near term. In the event
that such  milestones are not achieved or  achievement  is delayed,  the Company
would be required to enter into additional marketing, joint venture or licensing
agreements,  or obtain funds from other  sources  (which might include a debt or
equity financing) to provide adequate funding for continued operations. There is
no  assurance  that  the  milestones  in the  Warner-Lambert  agreement  will be
achieved, that any other revenue-generating  agreements will be entered into, or
that adequate  financing could be obtained on terms satisfactory to the Company.
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.  However,
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 typically encountered by enterprises
in the Company's stage of transition,  many 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.  The Company
and others are  conducting  research  on new  delivery  systems  for  Calcitonin
including  oral  technology.  There can be no  assurance  that the  Company  has
developed or will develop a suitable oral delivery  system 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. 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. During 1994, the Company completed construction of
a facility  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 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 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 a  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."
However,   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.  See "The
Company."  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.
 
         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 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 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 - 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. There
can  be  no  assurance  that  developments  by  others,   including  alternative
production  methods and new  delivery  systems for  Calcitonin  as well as 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 would have sufficient  resources to defend against or
satisfy any such claims.  Although the Company has product  liability  insurance
coverage in place,  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 and immunization  processes
and to an oral  Calcitonin  formulation  invented in the course of its  research
activities.  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  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 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  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 . See "The  Company."  The  regulatory
approval  process  for a  pharmaceutical  product may take a number of years and
requires  substantial  resources.  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,  or  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.
<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 490,000 shares of Common Stock to which
this  Prospectus  relates,  as of November  30,  1997,  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 2,661,000 shares of Common Stock issuable
upon exercise of outstanding  warrants at exercise prices ranging from $1.375 to
$3.50 per share;  and  approximately  1,317,000  shares of Common Stock issuable
upon exercise of options exercisable at prices ranging from $1.00 to $4.5625 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.  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
existing products or procedures,  proposed government regulations,  developments
<PAGE>
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.  As of October 31, 1997 the amount of the Company's net tangible assets
was approximately $11.3 million. 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
the holders of the Common Stock to resell the securities.

                                   THE COMPANY

         Unigene Laboratories,  Inc. is a health-care oriented biopharmaceutical
company that 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.   Certain   statements   under   this   caption   constitute
"forward-looking  statements"  under the Reform Act. See "Special Note Regarding
Forward-Looking  Statements."  The Company's  current business focus has shifted
toward  pharmaceutical  production  from its prior  emphasis  on  pharmaceutical
research.  The Company has  succeeded in  combining  its  proprietary  amidation
<PAGE>
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  Calcitonin  and  indicated  that  the
Company's process for producing  Calcitonin should reduce both the cost and time
required for commercial production of multi-kilogram quantities 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.  However,
the Company may retain  responsibility  for  clinical  testing and  applying for
regulatory  approval of certain  products.  To date, the Company has focused its
efforts  primarily  on  the  manufacture  and  therapeutic  delivery  of  salmon
Calcitonin, a product that is used in the treatment of osteoporosis.

         The Company has developed a proprietary oral delivery  technology which
has successfully  delivered  Calcitonin into the blood stream of human subjects.
The formulation,  which is the subject of international patent applications, has
been shown by clinical studies to reproducibly  deliver  significant  measurable
quantities of the hormone into the bloodstream. The Company believes that such a
formulation may expedite the regulatory  approval  process for a Calcitonin pill
because it should be easier to establish its performance efficacy as compared to
a formulation  that does not produce  measurable  Calcitonin  blood levels.  The
Company  has  licensed  its  oral  Calcitonin  technology   exclusively  to  the
Parke-Davis  division of Warner-Lambert  Company.  The Company believes that the
components  of the  proprietary  oral  formulation  will enable the  delivery of
peptides in addition to Calcitonin  and it has initiated  studies to investigate
such possibilities.

         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 current production capacity of the facility is between
0.5-1.0  kilogram  of  bulk  Calcitonin  per  year.  The  Company  is  following
conventional  procedures  to secure the approval of the  facility by  regulatory
agencies that will allow the Company to  manufacture  its  Calcitonin  for human
use.  Although the facility was inspected by an independent  consultant in early
1997  and  found to be in  compliance  with  cGMP  guidelines,  there  can be no
assurance that approval by such agencies will be obtained. 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
<PAGE>
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.  Although  the facility  will
initially be exclusively devoted to Calcitonin production,  it would be suitable
for producing  other peptide hormone  products in the future.  The design of the
facility is intended to allow for substantial increases in Calcitonin production
utilizing the existing  equipment and in March 1997, the Company  announced that
an improvement to its proprietary production process had been developed that can
boost the  Company's  annual  production  of  Calcitonin  by at least  fourfold.
However,  the successful  commercialization of a 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.  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 - Production Facility."
 
         In  addition  to  obtaining  approval  of the  facility  by  regulatory
agencies,  it is  necessary  to obtain  regulatory  approval in each country for
human use of the  Calcitonin  to be  produced  in the  facility.  This  requires
various human and animal  studies.  The Company or its licensees then must apply
to the  appropriate  regulatory  agencies  in the  applicable  jurisdiction  for
approval of the  Company's  Calcitonin  for human use. The  regulatory  approval
process for a  pharmaceutical  product  may take a number of years and  requires
substantial  resources.  During  1996,  the Company  received  authorization  to
proceed with pivotal clinical trials in the United States and the United Kingdom
for its injectable form of Calcitonin under the name  FORTICAL(R).  These trials
were  completed in early 1997 and  demonstrated  that the  Company's  injectable
FORTICAL product was bioequivalent to an injectable  salmon  Calcitonin  product
currently on the market.

         In September 1997, the Company's  registration dossier for its FORTICAL
Injection   product  was  formally   submitted  to  the  European  Union  health
authorities  for  approval.  It was the  Company's  first  product  registration
filing.  The 14,000 page  document  was  officially  accepted  for review by the
Committee  for  Proprietary  Medicinal  Products and the review  process has now
commenced.  The  European  dossier  was  filed  under  the  recently-established
centralized  procedure,  by which  the  product's  approval  would  be  obtained
simultaneously  in all of  the 15  member  nations  of the  European  Union.  In
addition,  an  approved  European  dossier  can be readily  cited by  regulatory
authorities in many non-European  nations,  which could significantly reduce the
registration requirements for FORTICAL,  thereby accelerating product launch, in
such countries.  The Company has completed all clinical trials necessary to file
a New  Drug  Application  ("NDA")  for  injectable  FORTICAL  with  the  FDA and
currently plans to file this application at a later date. Because the injectable
Calcitonin  market  in Europe is  larger  than  that in the U.S.,  the  European
dossier filing was a higher priority.

         The Company believes that the abbreviated  clinical program it has been
authorized to undertake will be sufficient to satisfy  approval  requirements in
the United States and the European Union.  The Company  believes that the review
process for the European dossier,  and possibly other filings for its injectable
Calcitonin  product,  may be shorter than that typically  associated  with a new
drug submission  because (i) the active ingredient is structurally  identical to
and  biologically  indistinguishable  from the  active  ingredient  in  products
already  approved  by  many  regulatory   agencies,   (ii)  the  formulation  is
essentially  similar  to the  formulations  used in  similar,  already  approved
products and (iii) the clinical trial program that was authorized was relatively
brief and involved small numbers of subjects,  so the amount of information that
must be  reviewed  is far less than would have been  compiled  for a typical new
drug  submission.  However,  there  can  be  no  assurance  that  the  necessary
governmental  approvals  will be  obtained  or that they will be  obtained on an
expedited basis. See "Risk Factors - Government Regulation."
<PAGE>
         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 during 1995 for the marketing of a
nasal spray  delivery  system for  Calcitonin,  which  could  enlarge the United
States  market  for  Calcitonin.  The  Company,  its  licensees  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.

         In December 1995 and January 1996,  the Company  successfully  tested a
proprietary Calcitonin oral formulation in Phase I clinical trials in the United
Kingdom.  These  studies  indicated  that the majority of those who received the
oral  Calcitonin  showed levels of the hormone in blood samples taken during the
trial which were greater  than the minimum  levels  generally  regarded as being
required for maximum therapeutic  benefit.  The Company believes that these were
the first studies to  demonstrate  that  significant  blood levels of Calcitonin
could be observed in humans  following oral  administration  of the hormone.  In
April 1996, the Company successfully conducted a third Phase I clinical trial in
the United Kingdom which utilized lower Calcitonin dosages than in the prior two
clinical  trials.  The results of this trial  indicated  that every test subject
showed  levels of the hormone in blood  samples taken during the trial in excess
of the minimum  levels  generally  regarded as required for maximum  therapeutic
benefit.  However,  there  can  be no  assurance  that  these  results  will  be
replicated in further studies. The Company has filed patent applications for its
oral formulation with the U.S. Patent and Trademark  Office.  Under the terms of
the agreement  with  Warner-Lambert  Company,  which has licensed the use of the
Company's oral Calcitonin technology,  Warner-Lambert has assumed responsibility
for obtaining  regulatory approval from the FDA and other regulatory agencies of
an oral  Calcitonin  product  using  the  Company's  proprietary  oral  delivery
technology. There can be no assurance that any of these patent applications will
be approved,  that  Warner-Lambert  will be successful  in obtaining  regulatory
approval of an oral Calcitonin  product or that  Warner-Lambert  and the Company
will be  successful  in  developing,  producing or marketing an oral  Calcitonin
product.

         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.  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 $6
million in payments from  Warner-Lambert,  consisting of a $3 million  licensing
fee and a $3 million  equity  investment by  Warner-Lambert  (695,066  shares of
Common Stock were  purchased at a price of  approximately  $4.32 per share).  In
addition,  the Company is eligible to receive up to an additional  $48.5 million
in milestone payments during the course of the development  program if specified
milestones  are achieved,  of which $15.5 million would be received prior to the
commencement  of  Phase  I  clinical  studies  in the  U.S.  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 has retained the right to license
the use of its technologies for injectable and nasal  formulations of Calcitonin
on a worldwide  basis.  Management is actively  seeking other  licensing  and/or
supply agreements with  pharmaceutical  companies for injectable and nasal forms
of   Calcitonin.   However,   there  is  no   assurance   that  any   additional
revenue-generating  agreements  will be signed.  See "Risk  Factors - History of
Losses;  Auditors' Report - Going Concern Considerations;  - Dependence on Large
Pharmaceutical Companies; - Risks of International Operations."

         The  Company  is  currently  engaged  in  two  collaborative   research
programs.  One,  with  Rutgers  University  College of  Pharmacy,  continues  to
investigate oral drug delivery technology for Calcitonin and other peptides. The
second  collaboration,   performed  in  conjunction  with  Yale  University,  is
<PAGE>
investigating   novel   applications  for  certain  amidated  peptide  hormones,
including  Calcitonin  gene-related  peptide  ("CGRP").  In  1996,  the  Company
reported that CGRP  accelerated bone growth and prevented bone loss in an animal
model system.  However,  there can be no assurance  that CGRP will have the same
effect in humans.

         The  Company  has  established  a  multi-disciplinary   team  to  adapt
proprietary  amidation,  biological production and oral delivery technologies to
the development of proprietary products and processes.  The Company, at November
30, 1997,  had 69  full-time  employees,  including 26 research and  development
personnel and 32 production  personnel.  Ten 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
(973) 882-0860.

                              SELLING SHAREHOLDERS


         The 490,000  shares of Common Stock  offered  hereby were issued to the
Selling  Shareholders  in February 1997 in exchange for the surrender of certain
contractual  rights  held by the  Selling  Shareholders  under  the  terms of an
agreement  pursuant  to  which  the  Company  issued  its  9.5%  Senior  Secured
Convertible   Debentures  (the   "Debentures")  to  the  Selling   Shareholders.
Specifically,  the shares  offered hereby were issued in  consideration  for the
cancellation  of an  obligation  of the Company  under the  agreement to pay the
Selling  Shareholders  a fee  equal to 2% of the sum of the  market  value as of
December 31, 1998 of all of the  Company's  outstanding  shares of Common Stock,
plus the principal amount of all outstanding debt of the Company,  less its cash
on  deposit,  up to a  maximum  fee  of  $3  million.  In  connection  with  the
transaction,  the  Company  agreed to register  the shares for resale  under the
Securities Act and to keep the registration  statement effective for a period of
three years from the date of issuance of the shares.

         In addition to the shares of Common Stock offered hereby, the Selling
Shareholders  own, or may immediately  acquire upon conversion of the Debentures
or the  exercise of certain  outstanding  warrants  (the "March  Warrants"),  an
aggregate of 674,148 shares of Common Stock (collectively,  the "March Shares").
The Debentures and the March Warrants were issued to the Selling Shareholders in
a private  transaction  completed  in March  1996.  All of the March  Shares are
registered  for resale by the  Selling  Shareholders  under the  Securities  Act
(Registration Statement No. 333-04557).

         The Selling  Shareholders also own, or may immediately acquire upon the
exercise of certain  outstanding  Class C and Class D warrants,  an aggregate of
136,902 shares of Common Stock (collectively, the "October Shares"). The Selling
Shareholders  purchased  such  warrants  and a portion of such  shares  from the
Company in a private  placement of detachable  units (the "Units")  completed in
<PAGE>
October 1996.  Each Unit  consisted of (i) one share of Common  Stock,  (ii) one
quarter of a Class C warrant, each whole Class C warrant exercisable immediately
to  purchase  one share of Common  Stock,  and  (iii) one  quarter  of a Class D
warrant,  each whole Class D warrant  exercisable  immediately  to purchase  one
share of Common Stock.  All of the October  Shares are  registered for resale by
the Selling  Shareholders  under the Securities Act (Registration  Statement No.
333-18079).

         Other than as described above,  neither of the Selling Shareholders has
had any position,  office or other material relationship with the Company or any
of its  predecessors  or affiliates  within the past three years.  The following
table  sets  forth  as of  November  30,  1997,  with  respect  to each  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 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  Shareholders
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  Shareholders,
if they desire,  to dispose of some or all of the Common  Stock  covered by this
Prospectus  at such times and at such prices as they  choose.  Whether  sales of
shares will be made,  and the timing and amount of any sale made,  is within the
sole discretion of the Selling Shareholders.
<PAGE>
         The Common  Stock  covered by this  Prospectus  may be offered for sale
from time to time by the  Selling  Shareholders  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  Shareholders 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
Shareholders.  The Selling  Shareholders  may also sell  Common  Stock short and
redeliver the shares to close out such short positions. The Selling Shareholders
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
Shareholders also may pledge the shares registered  hereunder to a broker-dealer
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 Selling Shareholders 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.

         Certain 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  Shareholders.  The  Selling  Shareholders  have 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
Shareholders 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.
<PAGE>
         The  Company has agreed to supply the  Selling  Shareholders  with such
number of copies of this Prospectus as they 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.

                                  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,

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
<PAGE>
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
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.
                           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;
<PAGE>
                  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  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.

Unigene Laboratories, Inc.

Fairfield, New Jersey 07004

Gentlemen:

                  This opinion is being  furnished to you in  connection  with a
Registration  Statement on Form S-3 (the  "Registration  Statement") being filed
today by Unigene  Laboratories,  Inc., a Delaware  corporation  (the "Company"),
with the  Securities  and  Exchange  Commission  (the  "Commission")  under  the
Securities Act of 1933, as amended,  for the  registration for resale of 490,000
shares (the  "Shares") of the Company's  common stock,  par value $.01 per share
(the "Common  Stock").  The Shares  offered by the  Registration  Statement were
issued by the Company in a February 1997 private transaction to the holders (the
"Holders")  of the  Company's  9.5% Senior  Secured  Convertible  Debentures  in
exchange for the surrender of certain contractual rights.

                  For   purposes  of  this   opinion,   we  have   examined  the
Registration Statement and the exhibits thereto and a copy the Letter Agreement,
dated February 7, 1997, among the Company and the Holders. We also have examined
and relied upon a copy of the Company's Certificate of Incorporation,  certified
by the Secretary of State of the State of Delaware,  and copies of the Company's
By-Laws  and  certain  resolutions  adopted  by the  Board of  Directors  of the
Company,  certified by the Corporate  Secretary of the Company.  We further have
examined  such other  documents  and made such other  investigations  as we have
deemed necessary to form a basis for the opinion hereinafter expressed.

                  In  examining  the  foregoing  documents,  we have assumed the
authenticity of documents  submitted to us as originals,  the genuineness of all
signatures, the conformity to original documents of documents submitted to us as
copies, and the accuracy of the representations and statements included therein.

                  Based on the foregoing,  we are of the opinion that the Shares
have  been  duly  authorized  and  validly  issued,   and  are  fully  paid  and
nonassessable.

                  We hereby  consent to the filing of this opinion as an exhibit
to the  Registration  Statement  and to the use of our  name  in the  Prospectus
forming a part thereof under the heading "Legal Matters."

                                                     Very truly yours,

                                                     /s/ Covington & Burling

                         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 13,  1997,
relating to the balance sheets of Unigene Laboratories,  Inc. as of December 31,
1996 and 1995 and the related  statements of operations,  stockholders'  equity,
and cash flows for each of the years in the three-year period ended December 31,
1996,  which report  appears in the December 31, 1996 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 13, 1997 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.

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