                               Prospectus Summary

     The following summary highlights  information  contained  elsewhere in this
prospectus.  It may not contain all of the information that is important to you.
You should  read the entire  prospectus  carefully,  especially  the  discussion
regarding the risks of investing in Unigene common stock under the heading "Risk
Factors,"  before investing in Unigene common stock.  "Unigene,"  "Forcaltonin,"
and "Fortical" are registered trademarks of Unigene Laboratories, Inc.

Business

     Unigene is a biopharmaceutical company engaged in the research,  production
and delivery of small proteins,  referred to as peptides, that have demonstrated
or may have potential medical use. We have a patented  manufacturing  technology
for producing many peptides  cost-effectively.  We also have patented technology
that has been  shown to  deliver  orally  medically  useful  amounts  of various
peptides into the bloodstream.  Our primary focus has been on the development of
Calcitonin  and other  peptide  products for the treatment of  osteoporosis  and
other indications.

     o    Injectable  Calcitonin.  Our injectable Calcitonin product,  which has
          the trade name  FORCALTONIN TM, has been approved for the treatment of
          Paget's  disease,  a  genetic  bone  disorder,  and  hypercalcemia,  a
          disorder  associated with high calcium blood levels,  in the 15 member
          states of the  European  Union.  This  product was approved in 2001 in
          Switzerland for the treatment of osteoporosis  and other  indications.
          Sales to date of this product have been minimal.

     o    Nasal  Calcitonin.  In 2000 and 2001, we successfully  completed human
          studies demonstrating similar blood levels between our formulation and
          that  of  an  existing  nasal  Calcitonin   product  and  also  showed
          significant  bone  marker  activity.  We  expect  to  file a New  Drug
          Application with the U.S. Food and Drug Administration  (FDA) in early
          2002.  We are seeking to license our nasal  Calcitonin  product in the
          U.S. and other countries for the treatment of osteoporosis.

     o    Oral Calcitonin.  In 1997, we entered into an agreement under which we
          granted to the Parke-Davis  division of Warner-Lambert  Company (which
          merged with Pfizer in June 2000), a worldwide license to make, use and
          sell our oral Calcitonin technology.  In December 1999, Warner Lambert
          filed an  Investigational  New Drug  application  with the FDA for the
          conduct of human  trials in the United  States of our oral  Calcitonin
          product as a treatment  for  osteoporosis.  Pfizer  began a Phase I/II
          human  study in April  2000 and  patient  dosing  for this  study  was
          completed in December 2000.  Pfizer  analyzed the results of the study
          and informed us in March 2001 that the study did not achieve  Pfizer's
          desired results.  Pfizer  terminated the license agreement citing this
          conclusion.  We  believe  that this  study,  in which an FDA  approved
          product also did not work and which produced  results contrary to many
          published  studies,  was not capable of determining the performance of
          our oral Calcitonin  product. We believe that if patients in the study
          had also received calcium supplements,  in addition to the Calcitonin,
          the results would have been more  favorable.  Therefore,  we intend to
          continue the development of our oral Calcitonin product as a treatment
          of osteoporosis,  and have begun discussions with potential  licensees
          in the U.S. and other countries.  In addition,  due to the termination
          of the Pfizer  agreement,  we no longer have  restrictions  on selling
          bulk Calcitonin.

     Our business strategy is to develop proprietary products and processes with
applications  in human  health  care to generate  revenues  from  license  fees,
royalties on  third-party  sales and direct sales of bulk or finished  products.
Generally,  we fund our  internal  research  activities  and  intend  to rely on
licensees,  which are  likely to be  established  pharmaceutical  companies,  to
provide development funding. We also generally expect to rely on these licensees
to take responsibility for obtaining  appropriate  regulatory  approvals,  human
testing,  and  marketing  of  products  derived  from our  research  activities.
However,  we may, in some cases, retain the responsibility for human testing and
for obtaining the required regulatory approvals for a particular product.

                                  Risk Factors

     An investment in Unigene  common stock  involves a high degree of risk. You
should carefully  consider the following  factors and other  information in this
prospectus  before  deciding to invest in shares of Unigene common stock. If any
of the  following  risks  actually  occur,  our business,  financial  condition,
results of operations and prospects for growth would likely suffer. As a result,
the trading price of Unigene common stock could decline,  and you could lose all
or part of your investment.

     Prospective  investors should consider  carefully these factors  concerning
our business before  purchasing the securities  offered by this  prospectus.  We
make  various  statements  in this  section  which  constitute  "forward-looking
statements"   under   Section   27A  of  the   Securities   Act  of  1933.   See
"Forward-Looking Statements."

We have significant historical losses and expect to continue to incur losses in
the future.

     We have incurred annual operating losses since our inception.  As a result,
at  September  30,  2001  we  had  an  accumulated   deficit  of   approximately
$85,000,000. Our gross revenues for the nine months ended September 30, 2001 and
the years ended  December 31,  2000,  1999 and 1998 were  $629,000,  $3,287,000,
$9,589,000 and  $5,050,000,  respectively.  However,  our revenues have not been
sufficient to sustain our operations.  These revenues  consisted  principally of
milestone  payments and other fees  received in connection  with our  terminated
license  agreement with Pfizer. As of September 30, 2001, we have no significant
revenue generating license agreements.  As a result, during the same periods, we
have incurred losses from operations of $8,146,000,  $11,385,000, $1,997,000 and
$6,060,000, respectively. Our net losses for the nine months ended September 30,
2001 and the years  ended  December  31,  2000,  1999 and 1998 were  $9,666,000,
$12,469,000, $1,577,000 and $6,881,000,  respectively. Our injectable Calcitonin
product has been approved for commercial sale in a number of European countries,
but we do not anticipate that these sales

                                       4



will produce significant  revenues. We believe that the profitability of Unigene
will require the successful  commercialization  of our nasal or oral  Calcitonin
products  or another  oral  peptide  product in the  United  States and  abroad.
Unigene might never be profitable.

We will require additional financing to sustain our operations.

     At September 30, 2001 we had a working capital  deficiency of approximately
$20,800,000.  The independent  auditors'  report for the year ended December 31,
2000,  includes an explanatory  paragraph stating that our recurring losses from
operations and working  capital  deficiency  discussed  above raise  substantial
doubt about our ability to continue as a going concern. We had an operating cash
flow deficit of $4,864,000 in 1998, an operating cash flow deficit of $1,400,000
in 1999 and for the year ended December 31, 2000, an operating cash flow deficit
of $3,382,000.  For the nine months ended September 30, 2001 we had an operating
cash flow deficit of $5,563,000.  We do not have sufficient  financial resources
to fund our operations at the current level. Therefore, we need additional funds
to continue  our  operations.  Our  agreement  with Fusion  Capital Fund II, LLC
("Fusion") has provided us with some cash to fund our  operations,  but it alone
has not been  sufficient to satisfy all of our working  capital needs.  From May
18, 2001 through November 30, 2001 we have raised a total of $1,380,800  through
the sale of 3,879,604 shares of our common stock to Fusion, before cash expenses
of approximately  $257,000. The extent to which we intend to rely on Fusion as a
source of financing will depend on a number of factors, including the prevailing
market  price and trading  volume of our common stock and the extent to which we
are able to secure working capital from other sources, such as through the entry
into  licensing  agreements  or the  sale of  Calcitonin,  both of  which we are
actively  exploring.  If we are  unable  to  enter  into a  significant  revenue
generating  license or financing  arrangement  in the near term, we will need to
significantly curtail our operations. We also could consider a sale or merger of
the company.  Should the funding we require to sustain our working capital needs
be unavailable or prohibitively  expensive the consequences  would be a material
adverse  effect on our  business,  operating  results,  financial  condition and
prospects.

     Even if we are able to access  $21,000,000  under the common stock purchase
agreement with Fusion,  we may still need additional  capital to fully implement
our business,  operating and  development  plans.  In addition,  our issuance of
shares of common stock to Fusion under the common stock purchase  agreement will
result in dilution to existing  stockholders.  We only have the right to receive
$43,750 per trading day under the common  stock  purchase  agreement  unless our
stock price equals or exceeds $4.00 per share, in which event the daily purchase
amount may be increased.  However, our sales of common stock to Fusion have been
below that level due to the share price and trading  volume of our common stock.
Fusion is not  obligated  to purchase  any shares of common stock on any trading
day that the market price is less than $.25.  In addition,  the agreement may be
terminated by Fusion at any time due to events of default  under the  agreement.
See "The Fusion  Transaction".  We believe that satisfying our long-term capital
requirements will require the successful commercialization of one of our peptide
products.  At this  time,  we  cannot  predict  with  certainty  that any of our
products will be commercially successful.

We may not be successful in our efforts to develop a Calcitonin or other peptide
product  that  will  produce   revenues  that  are  sufficient  to  sustain  our
operations.

     We  have  obtained  regulatory  approval  in  the  European  Union  and  in
Switzerland for the sale of our injectable  Calcitonin  product,  but there is a
limited market for the indications  for which it has been approved.  None of our
products  have  been  approved  for  sale in the  U.S.  The  U.S.  Food and Drug
Administration   must   approve   the   commercial   manufacture   and  sale  of
pharmaceutical  products in the U.S. Similar  regulatory  approvals are required
for the sale of  pharmaceutical  products outside of the United States.  We must
conduct  further human  testing on our products  before they can be approved for
commercial  sale.  We must show in these human trials that our products are safe
and effective.  All clinical trials for our nasal  Calcitonin  product have been
completed. If any of our products are approved for commercial sale, we will need
to  manufacture  the product in commercial  quantities  at a reasonable  cost in
order for it to be a successful  product that will generate profits.  Because of
our limited clinical,  manufacturing and regulatory experience and the lack of a
marketing  organization,  we are likely to rely on licensees or other parties to
perform one or more tasks for the commercialization of pharmaceutical products.

                                       5



     We believe that expanded consumer  acceptance of Calcitonin  pharmaceutical
products  depends on the  development  of more desirable  formulations.  We have
successfully  completed human trials to evaluate a nasal Calcitonin  product. An
NDA for our nasal  Calcitonin  product is  expected  to be filed in early  2002.
Pfizer  completed  a human  trial  for our oral  Calcitonin  product,  but after
analyzing the results it terminated our license  agreement citing scientific and
technical reasons.  We disagree with Pfizer's  conclusions and are seeking other
licensees to continue the development of our oral Calcitonin product. We may not
be successful in licensing our  Calcitonin  products or any of our other peptide
products.  In  addition,  we may  not be  able  to  demonstrate  the  safety  or
effectiveness  of our  products in human trials and,  accordingly,  they may not
receive the U.S. Food and Drug Administration and foreign governmental approvals
that are necessary to market these  products.  Other companies may develop other
products to compete with or surpass any nasal or oral product that we develop.

We have made a substantial  investment in our production  facility which we will
need to upgrade or expand in order to  manufacture  our  products in  commercial
quantities.

     We have  constructed  and are  operating  a  facility  intended  to produce
Calcitonin  and other  peptides.  This  facility  has been  approved by European
regulatory  authorities for the manufacture of Calcitonin for human use, but has
not yet been inspected or approved by the U.S. Food and Drug Administration. The
risks  associated  with this  facility  include the failure to achieve  targeted
production  and  profitability  goals,  the  development  by others of  superior
processes and products, and the absence of a market for products produced by the
facility.  In addition,  the successful  commercialization of an oral Calcitonin
product may require us to make additional  expenditures to expand or upgrade our
manufacturing  operations.  Currently, we cannot determine the cost or timing of
these capital expenditures.

We are dependent on partners for the commercial development of our products.

     We do not  currently  have,  nor do we expect  to have in the near  future,
sufficient  financial resources and personnel to develop and market our products
on our own. Accordingly, we expect to continue to depend on large pharmaceutical
companies  for  revenues  from  sales  of  products,  research  sponsorship  and
distribution  of our  products.  With  the  recent  termination  of  our  Pfizer
collaboration, we currently have no licenses for any of our products in the U.S.

     In June 2000, we entered into a joint venture with a pharmaceutical company
in the  People's  Republic  of China for the  manufacture  and  distribution  of
injectable  and nasal  Calcitonin  products  in China and  possibly  other Asian
markets,  for the  treatment  of  osteoporosis.  This joint  venture has not yet
commenced  operations  and it is uncertain  whether it will generate  meaningful
revenues  or  profits  for  Unigene.  We also  have  entered  into  distribution
agreements for our injectable  formulation of Calcitonin in the United  Kingdom,
Ireland and Israel.  To date, we have not received  material revenues from these
distribution agreements.

     We intend to pursue  additional  opportunities  to  license,  or enter into
distribution  arrangements  for,  our  oral,  nasal  and  injectable  Calcitonin
products as well as other possible peptide  products.  Due to the termination of
the Pfizer agreement, we no longer have restrictions on selling bulk Calcitonin.
However, we may not be successful in any of these efforts.

Because  we are a  biopharmaceutical  company,  our  operations  are  subject to
extensive government regulations.

     Our laboratory research,  development and production activities, as well as
those of our collaborators and licensees,  are subject to significant regulation
by federal,  state, local and foreign governmental  authorities.  In addition to
obtaining  U.S.  Food and Drug  Administration  approval  and  other  regulatory
approvals  of our  products,  we must  obtain  approvals  for our  manufacturing
facility to produce  Calcitonin and other peptides for human use. The regulatory
approval process for a pharmaceutical product requires substantial resources and
may take many years.  Our  inability to obtain  approvals or delays in obtaining

                                       6



approvals  would  adversely  affect our  ability  to  continue  our  development
program,  to  manufacture  and sell our  products,  and to receive  revenue from
milestone payments, product sales or royalties.

     The FDA or other regulatory  agencies may audit our production  facility at
any  time  to  ensure  compliance  with  current  Good  Manufacturing   Practice
guidelines,  referred to as cGMP. These  guidelines  require that we conduct our
production  operation  in  strict  compliance  with our  established  rules  for
manufacturing and quality controls. Any of these agencies can suspend production
operations and product sales if they find  significant or repeated  changes from
these  guidelines.  A suspension by any of these  agencies could have a material
adverse effect on our operations.

Our competitors include large pharmaceutical companies with superior resources.

     Unigene is engaged in a rapidly changing and highly  competitive  field. To
date,  Unigene  has  concentrated  its  efforts  primarily  on  one  product  --
Calcitonin -- for treating  osteoporosis and other indications.  During 2001, we
began  developing  other peptide  products,  including  parathyroid  hormone for
osteoporosis. Like the market  for any  pharmaceutical  product,  the market for
treating  osteoporosis and these other  indications has the potential for rapid,
unpredictable and significant technological change.  Competition is intense from
specialized biotechnology companies, major pharmaceutical and chemical companies
and  universities  and  research  institutions.  Most  of our  competitors  have
substantially  greater financial resources,  research and development staffs and
facilities, and regulatory experience than we do. Major competitors in the field
of osteoporosis treatment include Novartis,  American Home Products,  Merck, Eli
Lilly, and Procter and Gamble. Our main competitor in the field of oral delivery
of peptides is Emisphere Technologies,  Inc. Any one of these entities could, at
any time,  develop  products or a  manufacturing  process  that could render our
technology or products noncompetitive or obsolete.

Our  success  depends  upon our  ability to protect  our  intellectual  property
rights.

     We filed  applications  for U.S.  patents  relating to proprietary  peptide
manufacturing  technology  and oral  formulations  that we have  invented in the
course  of our  research.  To date,  six U.S.  patents  have  issued  and  other
applications  are  pending.  We have also made  patent  application  filings  in
selected foreign countries and numerous foreign patents have issued. We face the
risk  that any of our  pending  applications  will not  issue  as  patents.  Our
business also is subject to the risk that our issued patents will not provide us
with significant  competitive  advantages if, for example,  a competitor were to
independently  develop or obtain similar or superior  technologies.  Although we
believe our patents and patent  applications  are valid, the invalidation of our
key patents or the failure of our pending applications to issue as patents could
have a material adverse effect upon our business.

     We also rely on trade secrets to protect our  inventions.  Our policy is to
include confidentiality obligations in all research contracts, joint development
agreements and consulting relationships that provide access to our trade secrets
and other  know-how.  However,  other parties with  confidentiality  obligations
could breach their agreements  causing us harm. If a secrecy  obligation were to
be  breached,  we may not have the  financial  resources  necessary  for a legal
challenge.  If licensees,  consultants or other third parties use  technological
information  independently  developed by them or by others in the development of
our products,  disputes may arise from the use of this information and as to the
ownership rights to products  developed using this  information.  These disputes
may not be resolved in our favor.

Our technology or products could give rise to product liability claims.

     Our business exposes us to the risk of product  liability claims that are a
part of human testing, manufacturing and sale of pharmaceutical products. We may
not have  sufficient  resources  to defend  against  or  satisfy  these  claims.
Although we maintain product liability insurance coverage,  product liability or
other  judgments  against  us, as well as the cost of  defending  such claims in
excess of  insurance  limits,  could have a  material  adverse  effect  upon our
business and financial condition.

The loss of our key executives could have a negative effect on our business.

                                       7


     Dr.  Warren  Levy and Dr.  Ronald  Levy have been the  principal  executive
officers since our inception.  We rely on them for their leadership and business
direction.  Each of them has entered into an agreement with us providing that he
shall not  engage in any other  employment  or  business  for the  period of his
employment  with us.  The loss of the  services  of either of these  individuals
could have a material adverse effect on our business.

The outcome of our arbitration proceeding with The Tail Wind Fund is uncertain.

     In July  2000,  the Tail Wind  Fund,  Ltd.,  the  holder of  $2,000,000  in
principal  amount  of our 5%  convertible  debentures  filed  with the  American
Arbitration  Association a demand for arbitration of its claim that it was owed,
as of June 30, 2000, approximately $3,400,000, consisting of principal, interest
and  penalties,  resulting  from our default  under  various  provisions  of the
debentures   and  related   agreements.   See  "Business  --   Litigation"   and
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations  -- Capital  Resources and  Liquidity."  We have denied the amount of
Tail  Wind's  claim and have  made  certain  counterclaims.  In June  2001,  the
arbitration was postponed to allow Tail Wind and Unigene to engage in settlement
discussions.  The  outcome of these  negotiations  is  uncertain.  An  extremely
unfavorable  settlement  or  ruling  could  have a  material  adverse  effect on
Unigene.

The market price of our common stock may be highly unstable.

     The market  price of our common stock has been and we expect it to continue
to be highly  unstable.  Factors,  including our  announcement of  technological
improvements or announcements by other companies,  regulatory matters,  research
and development activities,  new or existing products or procedures,  signing or
termination of licensing  agreements,  concerns  about our financial  condition,
operating  results,  litigation,  resolution of the  arbitration  with Tail Wind
involving our outstanding  debentures,  government  regulation,  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 our stock.  In addition,  potential  dilutive  effects of
future sales of shares of Unigene common stock by Unigene and its  stockholders,
including  sales by Fusion and sales under this  prospectus  and by the exercise
and subsequent sale of Unigene common stock by the holders of other  outstanding
and future warrants and options could have an adverse effect on the price of our
stock.

We do not anticipate paying cash dividends on our common stock.

     We have never paid any cash dividends on our common stock and we do
not  anticipate  paying cash dividends in the  foreseeable  future.  Rather,  we
intend to retain  any cash flow we  generate  for  investment  in our  business.
Accordingly,  Unigene  common  stock may not be suitable for  investors  who are
seeking current income from dividends.

Our common stock is classified as a "penny stock" under SEC rules which may make
it more difficult for our stockholders to resell our common stock.

     Our common  stock is traded on the OTC  Bulletin  Board.  As a result,  the
holders  of our  common  stock may find it more  difficult  to  obtain  accurate
quotations  concerning  the  market  value of the stock.  Stockholders  also may
experience  greater  difficulties in attempting to sell the stock than if it was
listed on a stock exchange or quoted on the Nasdaq National Market or the Nasdaq
Small-Cap Market. Because Unigene common stock is not traded on a stock exchange
or 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 is
classified  as a "penny  stock." SEC Rule 15g-9 under the  Exchange  Act imposes
additional  sales practice  requirements  on  broker-dealers  that recommend the
purchase or sale of penny  stocks to persons  other than those who qualify as an
"established   customer"  or  an  "accredited   investor."   This  includes  the
requirement that a broker-dealer  must make a determination  that investments in
penny stocks are suitable for the customer and must make special  disclosures to
the customer  concerning  the risks of penny  stocks.  Application  of the penny
stock rules to the Unigene common stock could adversely

                                       8



affect the market liquidity of the shares,  which in turn may affect the ability
of holders of the Unigene common stock to resell the stock.

The sale of our common stock to Fusion could cause substantial  dilution and
the sale of the  shares  acquired  by Fusion  could  cause the price of  our
common stock to decline.

     The price at which  Fusion is  obligated  to purchase  shares of our common
stock under the common stock  purchase  agreement  will  fluctuate  based on the
market price of our common stock.  See "The Fusion  Transaction"  for a detailed
description of the purchase price.

     All of the shares offered for sale by Fusion are freely tradeable. However,
Fusion has agreed  that it will not sell or  otherwise  transfer  the  2,000,000
shares of common stock or the 1,000,000 shares of common stock issuable upon the
exercise of the warrant that we issued to Fusion as part of its  commitment  fee
until the earlier of the termination of the common stock purchase agreement, the
occurrence of an event of default by us under that agreement or May 2003. Fusion
may sell none,  some or all of the shares of common stock purchased from Unigene
at any time.  We have been advised by Fusion that the shares will be sold over a
period of up to 24 months from May 2001.  Depending upon market liquidity at the
time,  the resale by Fusion of shares at any given time could  cause the trading
price of our common stock to decline. The sale by Fusion of a substantial number
of shares  purchased from us, or the  anticipation of such sales,  could make it
more difficult for us to sell equity or equity related  securities in the future
at a time and at a price that we might otherwise wish to effect sales.

     If Fusion purchased the remaining balance of $19,475,800  purchasable under
the common stock purchase  agreement on the date of this prospectus,  at a price
equal to $.55,  the closing  sale price of our common stock on December 7, 2001,
Fusion would be able to purchase an additional  35,410,545  shares of our common
stock. These shares, along with the 2,000,000 shares and the 1,000,000 shares of
common  stock  issuable  upon the  exercise of the  warrant  which was issued to
Fusion as a commitment fee, would represent 44% of our outstanding  common stock
as of the date of this  prospectus,  assuming  that  Fusion  did not  resell any
shares. The issuance of these shares would result in significant dilution to the
ownership interests of other holders of our common stock. The amount of dilution
would be  higher  if the  market  price of our  common  stock is lower  than the
current market price at the time Fusion  purchases shares under the common stock
purchase  agreement,  as a lower  market  price  would  cause more shares of our
common stock to be issuable to Fusion.

The  existence  of the  agreement  with Fusion to purchase  shares of our common
stock could cause downward pressure on the market price of our common stock.

     Both the actual  dilution and the  potential  for dilution  resulting  from
sales of our common stock to Fusion  could cause  holders to elect to sell their
shares of our common  stock,  which  could  cause the  trading  price of our our
common stock to decrease. In addition,  prospective  investors  anticipating the
downward  pressure on the price of our common stock due to the shares  available
for sale by Fusion could refrain from purchases or cause sales or short sales in
anticipation of a decline of the market price.

                           Forward-Looking Statements

     Various  statements  that we make in this  prospectus  under  the  captions
"Prospectus Summary," "Risk Factors,"  "Management's  Discussion and Analysis of
Financial Condition and Results of Operations," "Business" and elsewhere in this
prospectus are "forward-looking statements" within the meaning of Section 27A of
the Securities Act of 1933. These  forward-looking  statements involve known and
unknown  risks,  uncertainties  and other  factors  that may  cause  the  actual
results,  performance or activities of our business,  or industry results, to be
materially  different  from  any  future  results,   performance  or  activities
expressed or implied by the forward-looking  statements.  These factors include:
general economic and business conditions, our financial condition,  competition,
our  dependence  on  other  companies  to  commercialize,  manufacture  and sell
products using our technologies,  the uncertainty of results of animal and human
testing,  the risk of product  liability and  liability  for human  trials,  our
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  for our products and other factors
discussed in this prospectus.

                             The Fusion Transaction

     On May 9, 2001,  we entered into a common  stock  purchase  agreement  with
Fusion  Capital  Fund II, LLC under  which  Fusion  agreed to  purchase  on each
trading day during the term of the  agreement  $43,750 of our common stock up to
an aggregate of $21 million.  The $21 million is to be purchased over a 24 month
period,  commencing  May 18, 2001,  subject to a six month  extension or earlier
termination at our discretion.  Through November 30, 2001 we have raised a total
of  $1,380,800  through  the sale of  3,879,604  shares of our  common  stock to
Fusion, before cash expenses of approximately $257,000.

     The daily purchase  amount may be decreased by us at any time. We also have
the right to increase the daily purchase amount at any time, provided,  however,
that we may not increase the daily  purchase  amount  above  $43,750  unless the
closing sale price of our stock is above $4.00 for five (5) consecutive  trading
days. Fusion has no obligation to purchase shares if the purchase price would be
less than $.25. The purchase price per share is equal to the lesser of:

     o    the lowest sale price of our common stock on the purchase date; or

     o    the average of the five (5) lowest  closing  sale prices of our common
          stock during the fifteen (15)  consecutive  trading days ending on the
          trading  day   immediately   preceding   such  purchase  date,  to  be
          appropriately  adjusted  for  any  reorganization,   recapitalization,
          non-cash dividend,  stock split or other similar transaction occurring
          during the fifteen (15) consecutive trading days.

     Fusion may not  purchase  shares of our common stock under the common stock
purchase agreement if Fusion and its affiliates would beneficially own more than
9.9% of our then  aggregate  outstanding  common  stock  immediately  after  the
proposed purchase.  If the 9.9% limitation is ever reached, this limitation will
not limit Fusion's obligation to fund the daily purchase amount.

     Fusion has agreed that neither it nor any of its affiliates  will engage in
any direct or indirect  short-selling  or hedging of our common stock during any
time prior to the termination of the common stock purchase agreement.

     Fusion may  terminate  the common  stock  purchase  agreement  without  any
liability  or payment to Unigene,  and would not be  required  to  purchase  any
additional  shares of common stock,  upon the occurrence of any of the following
events of default:

     o    if for any  reason  the  shares  cannot  be sold  for a  period  of 10
          consecutive  trading  days or for more than an aggregate of 30 trading
          days in any 365-day period;

     o    the  suspension  from  trading or  failure  of our common  stock to be
          listed  on the OTC  Bulletin  Board  for a  period  of 10  consecutive
          trading  days or for more than an  aggregate of 30 trading days in any
          365-day period;

     o    the  failure  of  Unigene  or the  Unigene  common  stock  to meet the
          requirements  for  continued  listing on the OTC Bulletin  Board for a
          period of 10 consecutive trading days or for more than an aggregate of
          30 trading days in any 365-day period;

     o    the failure of the transfer  agent to issue shares of our common stock
          in connection with a purchase;

     o    any breach of the representations or warranties or covenants contained
          in the common stock purchase agreement or any related agreements which
          has or which  reasonably  could be expected to have a material adverse
          affect on Unigene;

     o    a default of any  payment  obligation  of Unigene or any  acceleration
          prior to maturity in excess of $1.0 million; or

     o    commencement  of insolvency or  bankruptcy  proceedings  by or against
          Unigene.


     Fusion has received,  as  consideration  for its commitment to purchase our
common stock,  2,000,000  shares of our common stock and a five-year  warrant to
purchase  1,000,000  shares of our common stock,  exercisable at $.50 per share.
Unless an event of default occurs,  these shares and warrant shares must be held
by Fusion until the earlier of May 2003, or the  termination or a default under,
the agreement.


                                 Use of Proceeds

     We will not receive any of the proceeds  from the sale of the shares of our
common stock offered for sale under this prospectus.

                                 Dividend Policy

     We have  never paid a cash  dividend  on our  common  stock,  and we do not
anticipate  paying  cash  dividends  in  the  foreseeable  future.  Instead,  we
currently  plan to retain all earnings,  if any, for use in the operation of our
business and to fund future growth.

                             Selected Financial Data

     The selected  financial  data as of December 31, 2000 and 1999, and for the
years ended December 31, 2000,  1999 and 1998, that is set forth below have been
derived from Unigene's financial  statements included in this prospectus,  which
have been audited by KPMG LLP, independent accountants. The audit report of KPMG
LLP covering the December 31, 2000 financial  statements contains an explanatory
paragraph that states that the Company's  recurring  losses from  operations and
working capital deficiency raise substantial doubt about the entity's ability to
continue  as a going  concern.  The  financial  statements  do not  include  any
adjustments that might result from the outcome of that uncertainty. The selected
financial  data below as of December 31, 1998,  1997 and 1996, and for the years
ended  December 31, 1997 and 1996 have been  derived from our audited  financial
statements that are not included in this prospectus. The selected financial data
below as of and for the nine months ended September 30, 2001 and 2000, have been
derived from our unaudited  financial  statements,  included in this  prospectus
which, in our opinion,  include all adjustments,  consisting of normal recurring
adjustments,  necessary for a fair  presentation  of our financial  position and
results of operations.

     Historical results are not necessarily indicative of results to be expected
for  any  future   period.   You  should  read  the  data  below  together  with
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations"  and the financial  statements  and related  notes  included in this
prospectus.

In December  1999, the  Securities  and Exchange  Commission  staff issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB
101").  Prior to the  implementation  of SAB 101,  non-refundable  license  fees
received  upon  execution  of  license  agreements  were  recognized  as revenue
immediately.  SAB 101  summarizes  certain  of the  staff's  views  in  applying
generally  accepted  accounting  principles to revenue  recognition in financial
statements and specifically  addresses revenue

                                       13




recognition in the biotechnology  industry for non-refundable  technology access
fees and other  non-refundable  fees.  We were  required  to adopt  SAB 101,  as
amended,  in the  fourth  quarter of 2000 with an  effective  date of January 1,
2000, and the  recognition of a cumulative  effect  adjustment  calculated as of
January 1, 2000.

We adopted SAB 101 in 2000, changing our revenue recognition policy for up-front
licensing  fees  that  require  services  to be  performed  in the  future  from
immediate  revenue  recognition  to deferral of revenue  with the  up-front  fee
recognized over the life of the agreement.  In 1997, we recognized $3,000,000 in
revenue from an up-front  licensing  fee from  Pfizer.  With the adoption of SAB
101, we have recognized  this revenue over a 45 month period,  equivalent to the
term of our oral Calcitonin  agreement with Pfizer which was terminated in March
2001.  We  therefore  recognized  a non-cash  cumulative  effect  adjustment  of
$1,000,000  as of  January  1, 2000  representing  a revenue  deferral  over the
remaining  15  months  of the  agreement.  We  restated  the  accompanying  2000
financial  statements  for  the  cumulative  effect  adjustment  and  recognized
$200,000 of revenue in each of the quarters  through  March 31, 2001 as a result
of this  deferral.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations

     You  should  read the  following  discussion  together  with our  financial
statements and the notes appearing  elsewhere in this prospectus.  The following
discussion contains  forward-looking  statements.  Our actual results may differ
materially from those projected in the forward-looking statements.  Factors that
might cause  future  results to differ  materially  from those  projected in the
forward-looking  statements  include  those  discussed  in  "Risk  Factors"  and
elsewhere in this prospectus.

Nine months ended September 30, 2001 and 2000

     Revenue  for the third  quarter  of 2001  decreased  83% to  $268,000  from
$1,559,000 in the third  quarter of 2000.  Revenue for the third quarter of 2001
consisted  primarily of calcitonin sales.  Revenue for the third quarter of 2000
consisted  primarily of a $1,000,000  milestone from Pfizer,  analytical testing
services  provided to Pfizer, as well as the amortization of deferred revenue in
the amount of $200,000.  Revenue for the first nine months of 2001 decreased 79%
to $629,000 from  $2,961,000  in the first nine months of 2000.  Revenue for the
first nine months of 2001 consisted  primarily of $339,000 in calcitonin  sales,
$200,000 from the  amortization  of deferred  revenue from Pfizer and analytical
testing services  provided to Pfizer.  Revenue for the first nine months of 2000
consisted  primarily  of  revenue  from  Pfizer,  including  $600,000  from  the
amortization of deferred  revenue and $2,000,000  resulting from the achievement
of milestones in the development of an oral  Calcitonin  product as well as from
analytical testing services provided to Pfizer. In March 2001, Pfizer terminated
its license agreement with Unigene.

     Research and  development,  Unigene's  largest  expense,  decreased  21% to
$2,289,000  from  $2,905,000  for the three months ended  September 30, 2001, as
compared to the same period in 2000. The decrease was primarily  attributable to
decreased development expenses related to Unigene's nasal calcitonin product, as
well as  decreased  production  expenditures.  Research  and  development  costs
decreased 12% to $6,857,000  from $7,836,000 for the nine months ended September
30, 2001,  as compared to the same period in 2000.  The  decrease was  primarily
attributable  to reduced  expenditures  for the  development of Unigene's  nasal
calcitonin product, consulting fees and European regulatory filing fees.

     General and administrative expenses decreased 15% to $682,000 from $801,000
for the three months ended  September 30, 2001,  and decreased 21% to $1,919,000
from $2,418,000 for the nine months ended September 30, 2001, as compared to the
same periods in 2000.  The  decreases for the three month and nine month periods
ended  September 30, 2001 were primarily  attributable  to the  recognition of a
non-cash  expense  in 2000 of  $220,000  due to the  issuance  of a warrant to a
consultant,  partially  offset by increased legal fees in 2001. The decrease for
the nine  month  period  ended  September  30,  2001 was  also  affected  by the
recognition  of a $350,000  expense in June 2000 to terminate  Unigene's  former
joint venture in China.

     Interest  income  decreased  $3,000  or 71%  for  the  three  months  ended
September  30,  2001,  and  decreased  $34,000 or 83% for the nine months  ended
September  30,  2001,  as compared to the same  periods in 2000,  due to reduced
funds available for investment in 2001.

     Interest  expense  increased  $218,000  or 70% for the three  months  ended
September 30, 2001 to $530,000  from $312,000 and increased  $666,000 or 78% for
the nine months ended  September 30, 2001 to  $1,526,000  from $860,000 from the
corresponding  periods  in  2000.  Interest  expense  increased  in 2001  due to
increased officers' loans and higher interest rates on a portion of these loans.
Officers' loans to Unigene increased  $5,035,000 during the first nine months of
2001.  In  addition,  due to the fact that  Unigene did not make  principal  and
interest  payments on officers'  loans when due, the interest rate on $1,100,000
of these new loans and on $2,873,323  of prior loans  increased an additional 5%
per year and applied to both past due principal and  interest.  This  additional
interest was approximately  $382,000 for the first nine months of 2001. Interest
expense for both periods also was  affected by higher  interest  rates on the 5%
convertible   debentures.   The  annual  interest  rate  on  the  $2,000,000  in
outstanding  principal  amount  of the 5%  Debentures  increased  in 2000 to 20%
resulting  from the failure of Unigene to make a  semi-annual  interest  payment
that was due in January 2000. In addition,  since October 1999, Unigene has been
accruing

                                       15


additional interest expense monthly in an amount equal to 2% of the outstanding
principal amount of the 5% Debentures as a penalty for the removal of Unigene's
common stock from trading on the Nasdaq Stock Market.

     Effective  January 1, 2000,  Unigene adopted Staff Accounting  Bulletin No.
101,  "Revenue  Recognition in Financial  Statements"  (SAB 101) as described in
Note A to our September 30, 2001 unaudited condensed financial statements.  As a
result of the  adoption of SAB 101,  Unigene  recognized  a non-cash  cumulative
effect adjustment of $1,000,000 in the first quarter of 2000.

     Due to the  elimination  of revenue from Pfizer,  as well as an increase in
interest expense,  partially offset by decreased  operating  expenses,  net loss
increased  $777,000 or 32% to $3,232,000  from  $2,455,000  for the three months
ended September 30, 2001 from the corresponding period in 2000.

     Due to the  reduction  in revenue  from  Pfizer,  as well as an increase in
interest   expense,   partially  offset  by  the  cumulative  effect  adjustment
applicable  to 2000,  as well as a  decrease  in  operating  expenses,  net loss
increased $555,000 or 6% to $9,666,000 from $9,111,000 for the nine months ended
September 30, 2001 from the corresponding period in 2000.

Years ended December 31, 2000, 1999 and 1998

     Revenue.  Revenue  decreased 66% to $3,287,000  for the year ended December
31, 2000 as compared to $9,589,000 for the year ended December 31, 1999. Revenue
increased 90% to $9,589,000  for the year ended December 31, 1999 as compared to
$5,050,000  for the year ended  December 31, 1998.  In all three years,  revenue
consists   primarily  of  milestone  revenue  from  Pfizer  resulting  from  the
achievement of milestones in the development of an oral  Calcitonin  product for
treating  osteoporosis.  Yearly  revenue  was  affected  by  the  timing  of the
completion of the various  milestones.  In addition,  revenue for the year ended
December 31, 2000 included  $800,000 from the  amortization of deferred  revenue
related to the initial  licensing  fee paid by Pfizer in 1997 and  $345,000  for
analytical testing services provided to Pfizer. In March 2001, Pfizer terminated
its license agreement with the Company.

     Research and Development Expenses. Research and development,  the Company's
largest  expense,  increased 22% in 2000 to $11,484,000  from $9,375,000 in 1999
and  increased  4% in 1999  from  $9,042,000  in  1998.  The 2000  increase  was
primarily attributable to the Company's clinical trials for its nasal Calcitonin
product  and an increase in  expenditures  related to an increase in  Calcitonin
production  and the write-off of inventory in the fourth  quarter as a result of
Pfizer's  termination  of our  agreement,  partially  offset by a  reduction  in
consulting  fees  related to the Pfizer  collaboration.  The 1999  increase  was
primarily  attributable to development  expenses  related to the Company's nasal
Calcitonin  product,  consulting and analytical  testing expenses related to the
Company's  Type  II  variation  for  its  injectable   Calcitonin  product,  and
consulting  fees related to the Company's  collaboration  with Pfizer  partially
offset by a reduction in production  supplies.  Expenditures for the sponsorship
of collaborative research programs were $411,000, $250,000 and $280,000 in 2000,
1999 and 1998,  respectively,  which are  included as research  and  development
expenses.  A portion of these  expenditures was reimbursed by Pfizer in 1999 and
1998.

     General and Administrative  Expenses.  General and administrative  expenses
increased 44% in 2000 to $3,187,000  from $2,212,000 in 1999 and increased 7% in
1999  from  $2,068,000  in 1998.  The 2000  increase  was  primarily  due to the
recognition of non-cash  expenses of $220,000 due to the issuance of warrants to
a consultant  and stock  option  compensation  of  $399,000,  in addition to the
recognition  of a $350,000  expense to  terminate  the  Company's  former  joint
venture in China.  The 1999 increase was  primarily  due to increased  personnel
costs and  professional  fees partially offset by reductions in public relations
and travel expenses.

     Interest  Income.  Interest  income  increased  $12,000 or 31% in 2000 from
1999, after  decreasing  $70,000 or 65% in 1999 from 1998. The 2000 increase was
due to higher interest rates on investments.  The 1999 decrease was due to lower
interest income resulting from reduced funds available for investment.

     Interest  Expense.  Interest  expense  increased  $27,000  or 2% in 2000 to
$1,199,000 from $1,171,000 in 1999 after increasing $386,000 or 49% in 1999 from
$785,000 in 1998.  Interest  expense  increased in 2000 due to  increased  notes
payable  to  stockholders  and  to  higher  interest  rates  in  2000  on the 5%
convertible  debentures,  offset  by a  reduction  in  the  amortization  of the
beneficial  conversion  feature  and

                                       16



related  warrants on the 5%  convertible  debentures  as  compared to 1999.  The
annual interest rate on the $2,000,000 in outstanding principal amount of the 5%
Debentures increased in 2000 to 20% resulting from the failure of the Company to
make a semi-annual  interest  payment that was due in January 2000. In addition,
since October 1999, the Company has been accruing  additional  interest  expense
monthly in an amount equal to 2% of the outstanding  principal  amount of the 5%
Debentures as a result of the removal of the Company's Common Stock from trading
on the Nasdaq Stock Market in October 1999. The expenses  incurred in connection
with the 5%  Debentures in 2000 were  partially  offset by a 50% decrease in the
principal balance  outstanding as a result of conversions to Common Stock during
1999.  Included in 1999 interest  expense is $197,000 of the amortization of the
value of the beneficial conversion feature and related warrants of the Company's
5% convertible  debentures.  Excluding the change in the amortization charged to
interest,  interest expense increased in 1999 as compared to 1998 as a result of
an increase in notes payable to stockholders,  redemption premium resulting from
the Company exceeding the Share Limit on the 5% Debentures, and the 2% delisting
penalty on the 5%  Debentures,  partially  offset by a decrease  in the  balance
outstanding under the Company's 5% Debentures as a result of partial conversions
to Common Stock.

     Income Tax Benefit. Income tax benefit in 2000 of $1,065,000 and in 1999 of
$1,553,000  consisted  of  proceeds  received  for the sale of a portion  of the
Company's state tax net operating loss carryforwards under a New Jersey Economic
Development  Authority  ("NJEDA")  program,  which  allows  certain  New  Jersey
taxpayers to sell their state tax benefits to third parties.  The purpose of the
New  Jersey  program  is  to  provide  financial  assistance  to  high-tech  and
biotechnology companies in order to facilitate future growth and job creation.

     Extraordinary  Item.  Extraordinary  item, loss on early  extinguishment of
debt,  was $144,000 for 1998.  The loss was due to  redemption at a premium of a
portion of our 10% convertible debentures in September 1998.

     Cumulative  Effect of Accounting  Change.  In December 1999, the Securities
and Exchange Commission staff issued Staff Accounting Bulletin No. 101, "Revenue
Recognition in Financial Statements" ("SAB 101"). Prior to the implementation of
SAB  101,  non-refundable  license  fees  received  upon  execution  of  license
agreements were recognized as revenue immediately. SAB 101 summarizes certain of
the staff's  views in  applying  generally  accepted  accounting  principles  to
revenue recognition in financial  statements and specifically  addresses revenue
recognition in the biotechnology  industry for non-refundable  technology access
fees and other  non-refundable  fees. The Company was required to adopt SAB 101,
as amended,  in the fourth  quarter of 2000 with an effective date of January 1,
2000, and the  recognition of a cumulative  effect  adjustment  calculated as of
January 1, 2000.  The  Company  adopted  SAB 101 in 2000,  changing  its revenue
recognition  policy for  up-front  licensing  fees that  require  services to be
performed  in the future  from  immediate  revenue  recognition  to  deferral of
revenue with the  up-front fee  recognized  over the life of the  agreement.  In
1997, the Company  recognized  $3,000,000 in revenue from an up-front  licensing
fee from Pfizer.  With the  adoption of SAB 101, the Company is now  recognizing
this  revenue  over a 45  month  period,  equivalent  to the  term  of its  oral
Calcitonin agreement with Pfizer which was terminated in March 2001. The Company
therefore recognized a non-cash cumulative effect adjustment of $1,000,000 as of
January 1, 2000  representing a revenue deferral over the remaining 15 months of
the  agreement.  The  Company  recognized  $800,000  in revenue in 2000 and will
recognize $200,000 of revenue in 2001 as a result of this deferral.

     Net  Loss.  During  2000,   revenue  decreased   approximately   $6,300,000
principally  due to the timing of the  achievement of various  milestones in the
Pfizer  agreement.  In addition,  operating  expenses were higher as the Company
increased its product  commercialization  efforts including its nasal Calcitonin
clinical  trials.  Also,  the Company  recognized  a  cumulative  charge from an
accounting change offset by a realized income tax benefit.  Therefore,  net loss
increased  $10,892,000 for the year ended December 31, 2000 from the prior year.
During 1999,  revenue  increased  $4,540,000 from 1998 due to the achievement of
various  milestones in the Pfizer agreement.  In addition,  the Company received
$1,553,000 in 1999 from the partial sale of its state tax  benefits.  These were
partially offset by an increase in operating and

                                       17



interest expenses.  As a result, the Company's net loss decreased  $5,304,000 or
77% for the year ended December 31, 1999, from the prior year.

Liquidity and Capital Resources

     Unigene  maintains its peptide  production  facility on leased  premises in
Boonton,  New Jersey.  We began  production  under  current  Good  Manufacturing
Practice guidelines at this facility in 1996. The current lease expires in 2004.
Unigene has two consecutive ten-year renewal options under the lease, as well as
an option to  purchase  the  facility.  During  the first  nine  months of 2001,
Unigene   invested   approximately   $15,000  in  fixed  assets  and   leasehold
improvements.  Currently,  Unigene has no material  commitments  outstanding for
capital  expenditures  relating to either the Boonton facility or the office and
laboratory facility in Fairfield, New Jersey.

At September  30, 2001,  Unigene had cash and cash  equivalents  of $76,000,  an
increase of $59,000 from December 31, 2000.

     We do not have  sufficient  financial  resources  to  continue  to fund our
operations at the current level.  Unigene has incurred annual  operating  losses
since its inception and, as a result,  at September 30, 2001, had an accumulated
deficit  of  approximately  $85,000,000  and a  working  capital  deficiency  of
approximately  $20,800,000.  The independent auditors' report covering Unigene's
2000 financial  statements includes an explanatory  paragraph stating that these
factors  raise  substantial  doubt  about our  ability  to  continue  as a going
concern. However, the financial statements have been prepared on a going concern
basis and as such do not  include  any  adjustments  that might  result from the
outcome of this  uncertainty.  In October 1999, the Nasdaq Stock Market delisted
Unigene's  common  stock.  The delisting of our common stock may have an adverse
effect on our ability to raise capital.

     Our future ability to generate cash from operations  will depend  primarily
upon signing research or licensing  agreements,  achieving defined benchmarks in
such agreements that entitle Unigene to receive milestone payments and receiving
royalties from the sale of its licensed products.

     In July 1997,  Unigene  entered into an agreement under which it granted to
Warner-Lambert   Company  a  worldwide   license  to  use  its  oral  Calcitonin
technology. In June 2000, Pfizer Inc. acquired Warner-Lambert. Through September
30, 2001, we had received a total of $22.9 million from Pfizer  consisting of $3
million for an equity  investment,  $3 million for a licensing fee, $400,000 for
analytical  testing  services and  recognized  an aggregate of $16.5  million in
milestone revenue. Pfizer conducted a Phase I/II human study which was completed
in December 2000.  Pfizer analyzed the results of the study and informed Unigene
in March 2001 that the study did not achieve Pfizer's  desired  results.  Pfizer
terminated the license  agreement citing this  conclusion.  We believe that this
study,  in which an FDA approved  product  also did not work and which  produced
results contrary to many published  studies,  was not capable of determining the
performance  of our oral  Calcitonin  product.  Unigene  also  believes  that if
subjects in the study had also received calcium supplementation,  in addition to
the Calcitonin, the results would have been more favorable.  Therefore,  Unigene
intends  to  continue  the  development  of its  oral  Calcitonin  product  as a
treatment of osteoporosis, and has begun discussions with potential licensees in
the U.S. and other countries.  In addition, due to the termination of the Pfizer
agreement, we no longer have restrictions on selling bulk Calcitonin. During the
first  nine  months of 2001,  we sold a total of  $339,000  of bulk  calcitonin.
Unigene also has the right to license the use of its technologies for injectable
and nasal formulations of Calcitonin on a worldwide basis.  Unigene has licensed
distributors  in the United  Kingdom,  Ireland  and  Israel  for its  injectable
product.  However,  these distribution  agreements have not produced significant
revenues.  In June 2000, we entered into a joint venture agreement in China with
Shijiazhuang   Pharmaceutical  Group  ("SPG")  to  manufacture  and  market  our
injectable  and nasal  products.  Unigene is actively  seeking  other  licensing
and/or supply  agreements with  pharmaceutical  companies for its injectable and
nasal  Calcitonin  products and for other  pharmaceutical  products  that can be
manufactured  and/or  delivered  using its  patented  technologies,  and is also
exploring other

                                       18



opportunities including business combinations. However, we may not be successful
in our efforts to enter into any additional revenue generating agreements.

     Under the terms of the joint  venture  with SPG,  Unigene is  obligated  to
contribute up to $405,000 in cash during 2002 and up to an  additional  $495,000
in cash within two years  thereafter.  However,  these amounts may be reduced or
offset by Unigene's  share of joint venture  profits.  As of September 30, 2001,
Unigene had not made any contributions to the joint venture. We expect the joint
venture to begin  operations in the first quarter of 2002. In addition,  Unigene
is obligated to pay to the Qingdao General  Pharmaceutical  Company an aggregate
of $350,000 in 14 monthly installment  payments of $25,000 in order to terminate
its  former  joint  venture  in  China,  of which  $80,000  had been  paid as of
September 30, 2001. We recognized the entire  $350,000  obligation as an expense
in 2000.

     In June 1998,  Unigene  completed  a private  placement  of  $4,000,000  in
principal  amount of 5% convertible  debentures from which Unigene  realized net
proceeds of  approximately  $3,750,000.  The 5% debentures were convertible into
shares of Unigene's common stock. The interest on the debentures, at our option,
was  payable  in shares of common  stock.  Upon  conversion,  the holder of a 5%
debenture  was  entitled  to receive  warrants to purchase a number of shares of
common  stock  equal to 4% of the  number  of  shares  issued as a result of the
conversion.  However,  the  number of shares of common  stock that  Unigene  was
obligated to issue, in the aggregate,  upon  conversion,  when combined with the
shares issued in payment of interest and upon the exercise of the warrants,  was
limited to  3,852,500  shares.  After this share  limit was  reached,  we became
obligated to redeem all 5%  debentures  tendered for  conversion at a redemption
price equal to 120% of the principal amount, plus accrued interest.  In December
1999,  Unigene was unable to convert  $200,000 in principal of the 5% debentures
tendered for  conversion  because the  conversion  would have exceeded the share
limit. As a result, Unigene accrued, as of December 31, 1999, an amount equal to
$400,000 representing the 20% premium on the outstanding $2,000,000 in principal
amount of 5% debentures that had not been  converted.  As of September 30, 2001,
all of the  $2,000,000 in principal  amount of 5%  debentures  were tendered for
conversion and therefore are classified as a current  liability in the amount of
$2,400,000.  Through  September  30, 2001,  Unigene  issued a total of 3,703,362
shares of common stock upon conversion of $2,000,000 in principal  amount of the
5% debentures  and in payment of interest on the 5%  debentures.  Also,  Unigene
issued an additional  103,032 shares of common stock upon the cashless  exercise
of all of the 141,123 warrants issued upon conversion of the 5% debentures.

     On  January  5,  2000,  Unigene  failed  to make the  required  semi-annual
interest  payment on the  outstanding 5% debentures.  As a result,  the interest
rate on the  outstanding  5%  debentures  has  increased  to 20% per  year.  The
semi-annual interest payments due July 5, 2000, January 5, 2001 and July 5, 2001
also have not been  made.  As of  November  30,  2001,  the  accrued  and unpaid
interest on the 5% debentures totaled approximately  $833,000. In addition,  due
to the delisting of Unigene's  common stock from the Nasdaq  National  Market in
October 1999, we became  obligated under a separate  agreement to pay the holder
of the 5% debentures an amount equal to 2% of the outstanding  principal  amount
of the debentures per month. Unigene has not made any of these payments to date,
but has accrued the amounts as additional  interest expense.  As of November 30,
2001,  the  accrued  and unpaid  amount of this  penalty  totaled  approximately
$1,057,000.

     The holder of the 5% debentures has commenced an arbitration  proceeding in
which the holder claims that it is entitled, as of June 30, 2000, to payments in
respect of the 5% debentures in the amount of approximately $3,400,000. See Part
II, Item 1 - Legal Proceedings.

                                       19



     To satisfy Unigene's  short-term liquidity needs, Jay Levy, the Chairman of
the Board and an officer of Unigene,  and Warren Levy and Ronald Levy, directors
and officers of Unigene,  and another Levy family  member from time to time have
made loans to Unigene. During the first quarter of 2001, Jay Levy loaned Unigene
$1,600,000  and Warren Levy and Ronald Levy each made demand loans to Unigene of
$5,000. During the second quarter of 2001, Jay Levy made demand loans to Unigene
of  $1,950,000.  During the third quarter of 2001, Jay Levy made demand loans to
Unigene of $1,475,000.  From October 1, 2001 through November 30, 2001, Jay Levy
made demand  loans to Unigene of an  additional  $725,000.  Due to the fact that
Unigene did not make principal and interest  payments on certain loans when due,
interest on loans through March 4, 2001  increased an additional 5% per year and
is calculated on both past due principal and interest.  This additional interest
was  approximately  $382,000,  and total interest  expense on all Levy loans was
approximately  $793,000 for the first nine months of 2001. The Levys have waived
all default provisions  including  additional interest penalties due under these
loans through December 31, 2000. As of November 30, 2001, total accrued interest
on all Levy loans was  approximately  $1,909,000  and the  outstanding  loans by
these individuals to Unigene, classified as short-term debt, totaled $10,503,323
and consist of:

o    Loans from Jay Levy in the aggregate principal amount of $3,465,000,  which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill  Lynch  Margin  Loan Rate plus 5.25%  (11.25% at November 30, 2001)
     that are classified as short-term  debt. These loans were originally at the
     Merrill  Lynch  Margin  Loan Rate plus .25%.  These  loans are secured by a
     security  interest  in  Unigene's  equipment  and  real  property.  Accrued
     interest on these loans at November 30, 2001 was approximately $1,041,000.

o    Loans  from  Jay  Levy in the  aggregate  principal  amount  of  $1,870,000
     evidenced by term notes maturing  January 2002, and bearing interest at the
     fixed rate of 11% per year.  These loans were originally at 6%. These loans
     are secured by a security  interest  in all of  Unigene's  equipment  and a
     mortgage on Unigene's real property. The terms of the notes require Unigene
     to make installment payments of principal and interest beginning in October
     1999 and  ending in January  2002 in an  aggregate  amount of  $72,426  per
     month. No installment  payments have been made to date. Accrued interest on
     these loans at November 30, 2001 was approximately $377,000.

o    Loans from Jay Levy in the aggregate  principal  amount of $4,650,000 which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill Lynch Margin Loan Rate plus .25%,  (6.25% at November 30, 2001) and
     are  classified  as  short-term  debt and which are  secured  by a security
     interest  in certain of our  patents.  Accrued  interest  on these loans at
     November 30, 2001 was approximately $137,000.

o    Loans from Warren Levy in the aggregate  principal amount of $260,000 which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill  Lynch  Margin Loan Rate plus 5.25%  (11.25% at November  30, 2001)
     that are classified as short-term  debt. These loans were originally at the
     Merrill Lynch Margin Loan Rate plus .25%. An additional  loan in the amount
     of $5,000 bears interest at the Merrill Lynch Loan Rate plus .25% (6.25% at
     November 30, 2001) and is classified as  short-term  debt.  These loans are
     secured by a secondary  security  interest in Unigene's  equipment and real
     property.  Accrued  interest  on  these  loans  at  November  30,  2001 was
     approximately $178,000.

o    Loans from Ronald Levy in the aggregate  principal amount of $248,323 which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill  Lynch  Margin Loan Rate plus 5.25%  (11.25% at November  30, 2001)
     that are classified as short-term debt. These loans were

                                       20



     originally  at the Merrill  Lynch Margin Loan Rate plus .25%. An additional
     loan in the amount of $5,000  bears  interest at the Merrill  Lynch  Margin
     Loan Rate plus .25%  (6.25%  at  November  30, 2001) and is  classified  as
     short-term debt. These loans are secured by a secondary  security  interest
     in Unigene's  equipment and real property.  Accrued interest on these loans
     at November 30, 2001 was approximately $176,000.

     Unigene's   cash   requirements   to  operate  its   research  and  peptide
manufacturing  facilities and develop its products are  approximately  $10 to 11
million  per  year.  In  addition  to its  obligations  with  respect  to the 5%
Debentures, Unigene has principal and interest obligations over the next several
years under its  outstanding  notes payable to the Levys, as well as obligations
relating to its current and former joint ventures in China.

     We  are  actively   seeking   licensing   and/or  supply   agreements  with
pharmaceutical  companies for oral,  nasal and injectable forms of Calcitonin as
well as for other oral peptides.  However, we may not be successful in licensing
any of our products.

     Under the agreement with Fusion Capital,  Unigene has the contractual right
to sell to Fusion,  subject to certain  conditions,  at the then current  market
price,  on each  trading  day  during the term of the  agreement  $43,750 of its
common  stock  up to an  aggregate  of  $21,000,000.  See  Notes  B and F to our
September  30,  2001  unaudited  condensed  financial  statements.  The Board of
Directors has authorized the sale to Fusion of up to 6,000,000 shares of Unigene
common stock. From May 18, 2001, through November 30, 2001, Unigene has received
approximately  $1,381,000 through the sale of 3,879,604 shares to Fusion, before
cash  expenses of  approximately  $257,000.  Our sales of common stock to Fusion
have been below the maximum  level due to the share price and trading  volume of
our  common  stock.  As a  result,  we are  still  borrowing  from the  Levys to
supplement the funding of our operations. Depending on the price at which shares
are sold,  Fusion could provide Unigene with  sufficient  funding to sustain its
operations  for up to two years,  beginning in the second  quarter of 2001.  The
ability  of  Unigene  to  realize  these  funds  will  depend on its  continuing
compliance with the Fusion Agreement.

     The  extent to which we intend to utilize  Fusion as a source of  financing
will depend on a number of factors, including the prevailing market price of our
common stock and the extent to which we are able to secure working  capital from
other sources,  such as through the entry into licensing  agreements or the sale
of  calcitonin,  both of which we are  actively  exploring.  If we are unable to
enter into a significant  revenue generating license or other arrangement in the
near term, we would need either to secure  another source of funding in order to
satisfy our working capital needs or  significantly  curtail our operations.  We
also could  consider  a sale or merger of the  company.  Should  the  funding we
require to sustain our working  capital needs be  unavailable  or  prohibitively
expensive when we require it, the consequence would be a material adverse effect
on our business,  operating results, financial condition and prospects.  Unigene
believes  that  satisfying  its  capital  requirements  over the long  term will
require  the  successful  commercialization  of its  oral  or  nasal  Calcitonin
products or another peptide product in the United States and abroad. However, it
is  uncertain  whether or not any of its  products  will be  approved or will be
commercially  successful.   In  addition,  the  commercialization  of  its  oral
Calcitonin product may require Unigene to incur additional capital  expenditures
to expand or upgrade its  manufacturing  operations.  Unigene  cannot  determine
either the cost or the timing of such capital expenditures at this time.

                                       21



     As of December  31,  2000,  Unigene had  available  for federal  income tax
reporting purposes net operating loss carryforwards in the approximate amount of
$68,000,000,  expiring  from 2001 through  2020,  which are  available to reduce
future  earnings which would  otherwise be subject to federal income taxes.  For
the nine months ended  September 30, 2001, we accumulated  additional  losses of
approximately  $9,666,000.  In addition,  as of December  31, 2000,  Unigene has
research and development credits in the approximate amount of $2,750,000,  which
are available to reduce the amount of future federal income taxes. These credits
expire  from  2001  through  2020.   Unigene  has  New  Jersey   operating  loss
carryforwards  in the  approximate  amount of  $23,300,000,  expiring  from 2004
through  2007,  which are  available  to reduce  future  earnings,  which  would
otherwise  be subject to state  income tax. As of  September  30, 2001 these New
Jersey loss  carryforwards have been approved for future sale under a program of
the New Jersey Economic Development Authority (the "NJEDA"). In order to realize
these benefits,  Unigene must apply to the NJEDA each year and must meet various
requirements for continuing eligibility.  In addition, the program must continue
to be funded by the State of New Jersey,  and there are limitations based on the
level of participation by other companies. As a result, future tax benefits will
be  recognized in the financial  statements as specific  sales are approved.  In
November  2001,  the NJEDA approved a portion of our New Jersey tax benefits for
current sale. We have  agreements in place to sell these tax benefits and expect
to realize approximately $800,000 in December 2001 and January 2002.

     Unigene follows Statement of Financial Accounting Standards (SFAS) No. 109,
"Accounting  for Income  Taxes."  Given our past history of incurring  operating
losses,  any deferred tax assets that are  recognizable  under SFAS No. 109 were
fully reserved.  As of December 31, 2000 and 1999,  under SFAS No. 109,  Unigene
had  deferred  tax  assets  of   approximately   $29,000,000  and   $26,000,000,
respectively,  subject to valuation  allowances of $29,000,000 and  $26,000,000,
respectively.  The deferred tax assets are  primarily a result of the  Company's
net operating losses and tax credits.  For the nine-month period ended September
30, 2001,  Unigene's deferred tax assets and valuation allowances each increased
by approximately $3,000,000.

Other

     Our common stock was delisted  from the Nasdaq  National  Market  effective
October 5, 1999 and is now  trading on the OTC  Bulletin  Board.  In order to be
relisted on the Nasdaq National Market or the Nasdaq  SmallCap  Market,  we must
meet the initial listing requirements.

Market Risk

     In the normal  course of business,  Unigene is exposed to  fluctuations  in
interest  rates  due to the use of debt as a  component  of the  funding  of its
operations.  Unigene  does not employ  specific  strategies,  such as the use of
derivative  instruments  or  hedging,  to manage  its  interest  rate  exposure.
Unigene's  interest rate exposure on the 5% debentures  has been affected by our
delisting from the Nasdaq  National  Market and failure to make the  semi-annual
interest  payment  in  January  2000.  Beginning  in the first  quarter of 2001,
Unigene's  interest  rate  exposure on its notes  payable-stockholders  has been
affected  by its  failure to make  principal  and  interest  payments  when due.
Unigene's  exposure  to  interest  rate  fluctuations  over the  near-term  will
continue to be affected by these events.

     The information  below  summarizes  Unigene's  market risks associated with
debt  obligations as of September 30, 2001.  The table below presents  principal
cash flows and related  interest rates by year of maturity based on the terms of
the debt.

     Under the terms of the 5% debentures, no additional shares may be issued to
convert the remaining principal balance. Therefore, the information presented as
to the debentures is without  consideration as to conversion features.  Variable
interest  rates  disclosed  represent  the rates at September  30,  2001.  Given
Unigene's  financial condition described in "Liquidity and Capital Resources" it
is not  practicable  to  estimate  the fair  value of our  debt  instruments  at
September 30, 2001.

                                    Business

Overview

     Unigene is a biopharmaceutical company engaged in the research,  production
and delivery of small proteins,  referred to as peptides, that have demonstrated
or may have potential medical use. We have a patented  manufacturing  technology
for producing many peptides  cost-effectively.  We also have patented technology
that has been  shown to  deliver  orally  medically  useful  amounts  of various
peptides, into the bloodstream. Our primary focus has been on the development of
Calcitonin  and other  peptide  products for the treatment of  osteoporosis  and
other  indications.  We have the facilities and the technology for manufacturing
Calcitonin in accordance  with cGMP and have an  injectable  Calcitonin  product
that is approved for sale in Switzerland for the treatment of  osteoporosis  and
in the  European  Union for two minor  indications.  We are also  engaged in the
development  of oral  and  nasal  Calcitonin  products.  During  2001,  we began
developing   other  peptide   products,   including   parathyroid   hormone  for
osteoporosis.

Our Accomplishments

     Among our major accomplishments are:

     o  Development  of a Proprietary  Peptide  Production  Process.  One of our
principal  scientific  accomplishments  is our  success in  developing  a highly
efficient   biotechnology-based  peptide  production  process.  Several  patents
relating  to this  process  have  issued.  We  believe  that  these  proprietary
processes  are  key  steps  in the  more  efficient  and  economical  commercial
production of peptides with various medical applications. Many of these peptides
cannot be produced  at a  reasonable  cost in  sufficient  quantities  for human
testing or commercial use by currently available production processes. Using our
proprietary  process,  we have produced  laboratory-scale  quantities of various
peptides.  We  have  constructed  and are  operating  a  manufacturing  facility
employing this process to produce Calcitonin.

     o Development  of Proprietary  Technology  for Oral Delivery.  We have also
developed  and patented a formulation  that has  successfully  delivered  orally
Calcitonin into the bloodstream of human subjects. We and our collaborators have
shown in  repeated  human  studies  that  this  formulation  regularly  delivers
measurable quantities of the peptide into the human bloodstream. We believe that
this  formulation  may accelerate the  regulatory  approval  process for an oral
Calcitonin  product  because it should be easier to establish its performance as
compared to a  formulation  that does not produce  measurable  Calcitonin  blood
levels.  We believe that the  components  of our patented  oral product also can
enable  the  delivery  of  other  peptides  and we  have  initiated  studies  to
investigate this possibility internally and in collaboration with others. During
2001, we reported successful oral delivery in animal studies of various peptides
including parathyroid hormone for osteoporosis and insulin for diabetes.

Strategy

     Our business strategy is to develop proprietary products and processes with
applications  in human  health  care to generate  revenues  from  license  fees,
royalties on  third-party  sales and direct sales of bulk or finished  products.
Generally, we fund our internal research activities and rely on licensees, which
are likely to be established  pharmaceutical  companies,  to provide development
funding.   We  also  generally  expect  to  rely  on  these  licensees  to  take
responsibility for obtaining appropriate  regulatory  approvals,  human testing,
and marketing of products derived from our research activities. However, we may,
in some cases, retain the responsibility for human testing and for obtaining the
required regulatory approvals for a particular product.

     o Pfizer  License  Agreement.  In July 1997,  we entered  into an agreement
under which we granted to the  Parke-Davis  division of  Warner-Lambert  Company
(which  merged with Pfizer in June  2000),  a worldwide  license to use our oral
Calcitonin technology.  Upon signing the agreement,  we received $6.0 million in
payments from  Warner-Lambert,  consisting of a $3.0 million licensing fee and a
$3.0 million equity investment by Warner-Lambert.  Through December 31, 2000, we
recognized  an aggregate of $16.5 million in revenue due to the  achievement  of
specified milestones,  including $2.0 million in 2000. Pfizer began a Phase I/II
human study in April 2000 and patient  dosing was  completed  in December  2000.

                                       25



Pfizer  analyzed the results of the study and informed us in March 2001 that the
study did not achieve Pfizer's desired  results.  Pfizer  terminated the license
agreement  citing this  conclusion.  We believe that this study, in which an FDA
approved  product also did not work and which produced  results contrary to many
published  studies,  was not capable of determining  the performance of our oral
Calcitonin  product.  We believe that if patients in the study had also received
calcium supplements,  in addition to the Calcitonin, the results would have been
more  favorable.  Therefore,  we intend to continue the  development of our oral
Calcitonin  product as a treatment of osteoporosis,  and have begun  discussions
with potential  licensees in the U.S. and other countries.  In addition,  due to
the  termination  of the Pfizer  agreement,  we no longer have  restrictions  on
selling bulk Calcitonin.

     o China Joint  Venture.  In June 2000, we entered into a joint venture with
Shijiazhuang  Pharmaceutical  Group  ("SPG"),  a  pharmaceutical  company in the
People's  Republic of China.  The joint venture will  manufacture and distribute
injectable and nasal  Calcitonin  products in China (and possibly other selected
Asian  markets)  for the  treatment  of  osteoporosis.  We own 45% of the  joint
venture and will receive 45% of the joint venture profits. In the first phase of
the  collaboration,  SPG will  contribute  its  existing  injectable  Calcitonin
license to the joint  venture,  which  will allow the joint  venture to sell our
product in China. A New Drug Application for its injectable and nasal Calcitonin
products has been filed in China. In addition, the joint venture may be required
to conduct brief local human  trials.  If the product is  successful,  the joint
venture  may  establish  a  facility  in  China  to fill  injectable  and  nasal
Calcitonin  products using bulk Calcitonin  produced at our Boonton,  New Jersey
plant. Eventually the joint venture may manufacture the bulk Calcitonin in China
at a new facility that would be  constructed  by the joint  venture.  This would
require  local  financing by the joint  venture.  The joint  venture has not yet
begun  operations as of September 30, 2001. We expect  operations to commence in
the first quarter of 2002.

     o Other  License or  Distribution  Arrangements.  In  addition to the joint
venture  with  SPG,  we  have  entered  into  distribution  agreements  for  our
injectable  Calcitonin  product in the United  Kingdom,  Ireland and Israel.  We
continue to seek other licensing or distribution  agreements with pharmaceutical
companies for both the injectable and nasal Calcitonin products. However, we may
not be  successful  in our  efforts to sign any  additional  revenue  generating
agreements.

Competition

     Our  primary  business  activity  has  been   biotechnology   research  and
development.  Biotechnology research is highly competitive,  particularly in the
field of human health care. We compete with specialized biotechnology companies,
major  pharmaceutical and chemical companies,  universities and other non-profit
research organizations,  many of which can devote considerably greater financial
resources to research activities.

     In 1999, we began  manufacturing  cGMP Calcitonin for use in pharmaceutical
products.  In the  development,  manufacture  and sale of peptide  products,  we
compete with contract laboratories and major pharmaceutical  companies.  Many of
our competitors can devote  considerably  greater  financial  resources to these
activities.  Major  competitors in the field of osteoporosis  include  Novartis,
American  Home  Products,  Merck,  Eli Lilly,  and Procter and Gamble.  Our main
competitor in the field of oral delivery of peptides is Emisphere  Technologies,
Inc.

     We believe that the unique safety and effectiveness of Calcitonin, combined
with  our  patented  peptide   manufacturing   process  and  our  patented  oral
formulation, will enable us to compete with products marketed by these and other
companies.

     We believe  that  success in  competing  with  others in the  biotechnology
industry will be based  primarily upon  scientific  expertise and  technological
superiority.  We also  believe  that  success  will be based on the  ability  to
identify  and  to  pursue   scientifically   feasible  and  commercially  viable
opportunities and to obtain  proprietary  protection for research  achievements.
Our success will further depend on our ability to obtain adequate funding and on
developing, testing, protecting,  producing and marketing products and obtaining
their timely regulatory approval.  We are always at risk that others may develop
superior  processes  or products  that would  render our  processes  or products
noncompetitive or obsolete.

                                       26



Product Manufacture

     We have been producing salmon  Calcitonin since 1992. We constructed a cGMP
facility for the production of Calcitonin at leased premises located in Boonton,
New Jersey. The facility began producing salmon Calcitonin under cGMP guidelines
in 1996. The facility also produces our proprietary  amidating enzyme for use in
producing  Calcitonin.  The current  production level of the facility is between
one and two kilograms of bulk Calcitonin per year.

     The facility can be modified to increase  Calcitonin  production  capacity.
However, if we are successful in our efforts to commercialize an oral Calcitonin
product,  we  expect  that we may  incur  additional  expenditures  to expand or
upgrade our manufacturing operations. Although the facility initially is devoted
exclusively to Calcitonin  production,  it also is suitable for producing  other
peptide products.

     We are  following  conventional  procedures  to secure the  approval of the
facility by regulatory agencies to allow us to manufacture  Calcitonin for human
use. European health  authorities  inspected the facility in connection with the
filing of our  injectable  Calcitonin  dossier and found it to be in  compliance
with cGMP guidelines.  However,  there is the risk that our operations might not
remain in compliance  or that  approval by other  agencies will not be obtained.
The FDA must approve the facility in order to  manufacture  Calcitonin  or other
peptides for sale in the United States.

Government Regulation

     Our laboratory research, development and production activities and those of
our  collaborators  are subject to significant  regulation by numerous  federal,
state, local and foreign governmental authorities.  FDA approval,  following the
successful  completion of various animal and human studies,  is required for the
sale of a  pharmaceutical  product in the United  States.  Foreign sales require
similar studies and approval by regulatory agencies.

     The  regulatory  approval  process for a  pharmaceutical  product  requires
substantial  resources  and can  take  many  years.  There  is a risk  that  any
additional  regulatory approvals required for our production facility or for any
of our  products  will not be  obtained in a timely  manner.  Our  inability  to
obtain,  or delays in obtaining,  these  approvals  would  adversely  affect our
ability to continue to fund our programs,  to produce marketable products, or to
receive  revenue from milestone  payments,  product sales or royalties.  We also
cannot predict the extent of any adverse governmental  regulation that may arise
from future legislative and administrative action.

     The FDA or other regulatory  agencies may audit our production  facility to
ensure that it is  operating  in  compliance  with  current  Good  Manufacturing
Practice  guidelines,  referred  to  as  cGMP.  These  guidelines  require  that
production  operations be conducted in strict  compliance  with our  established
rules for manufacturing  and quality  controls.  These agencies are empowered to
suspend  production  operations  and/or  product  sales  if,  in their  opinion,
significant  or  repeated  changes  from  these  guidelines  have  occurred.   A
suspension by any of these agencies could have a material  adverse impact on our
operations.

Regulatory Approval of Our Injectable Calcitonin Product

     In January  1999,  we received  approval  from the European  Committee  for
Proprietary  Medicinal  Products,  referred  to  as  the  CPMP,  to  market  our
injectable Calcitonin product in all 15 member states of the European Union as a
treatment  for Paget's  disease and for  hypercalcemia.  We began to market this
product in Europe for these  indications in 1999. We have filed a  supplementary
submission  with the CPMP,  called a Type II  Variation,  to expand the approved
indications to include the treatment of osteoporosis.  However,  it is uncertain
whether or when the Type II Variation  will be approved by the CPMP. In 2001, we
received an approval in Switzerland for our injectable  Calcitonin  product that
includes an osteoporosis indication.

                                       27



     Regulatory  authorities in many  non-European  Union countries can cite the
approved  European  dossier,  which we believe  could  significantly  reduce the
registration  requirements for injectable Calcitonin in those non-European Union
countries,  and thereby could speed up product launch.  In addition,  we believe
that the human trials conducted to support the European filing of the injectable
Calcitonin  product can be used to support the filing of a New Drug  Application
with the FDA for use of our injectable  Calcitonin product to treat osteoporosis
and other indications.  We believe that our abbreviated clinical program,  which
has  been  accepted  by  the  FDA,  will  be  sufficient  to  satisfy   approval
requirements in the United States and other  countries.  Accordingly,  we expect
that the review  process  for our  injectable  Calcitonin  product in the United
States and other countries may be shorter than that typically  associated with a
new drug submission for numerous reasons:

     o    The   active    ingredient   is   structurally    identical   to   and
          indistinguishable  from the  active  ingredient  in  products  already
          approved by many regulatory agencies.

     o    The  formulation is essentially  similar to the  formulations  used in
          already approved products.

     o    The human trial  program  that was  accepted by the FDA is  relatively
          brief and involved small numbers of subjects.  As a result, the amount
          of information  that must be reviewed is far less than would have been
          compiled  for the  lengthier  trials  required  for a typical new drug
          submission.

Development of our Oral Calcitonin Product

     In December  1995 and January 1996,  we  successfully  tested a proprietary
Calcitonin oral formulation in two separate human studies in the United Kingdom.
These studies  indicated that the majority of those who received oral Calcitonin
showed  levels of the peptide in blood  samples taken during the trial that were
greater than the minimum levels generally regarded as being required for maximum
medical  benefit.  We believe that these were the first  studies to  demonstrate
that  significant  blood  levels  of  Calcitonin  could be  observed  in  humans
following oral  administration  of the peptide.  In April 1996, we  successfully
conducted  a third  pilot  human  study in the United  Kingdom  which used lower
Calcitonin dosages than in the prior two human trials. The results of this trial
indicated  that every test subject  showed  levels of the peptide in their blood
samples that  exceeded  the minimum  levels  generally  regarded as required for
maximum medical  benefit.  During 1999,  with  Warner-Lambert  (now Pfizer),  we
successfully  concluded  two  pilot  human  studies  using  an  oral  Calcitonin
formulation  manufactured  by  Warner-Lambert.  Both studies showed  significant
measurable blood levels of Calcitonin. In December 1999, Warner-Lambert filed an
Investigational  New Drug  application with the FDA, a Phase I/II study began in
April 2000 and patient  dosing for this study was  completed  in December  2000.
Pfizer  analyzed the results of the study and informed us in March 2001 that the
study did not achieve Pfizer's desired  results.  Pfizer  terminated the license
agreement  citing this  conclusion.  We believe that this study, in which an FDA
approved  product also did not work and which produced  results contrary to many
published  studies,  was not capable of determining  the performance of our oral
Calcitonin  product.  We believe that if patients in the study had also received
calcium supplements,  in addition to the Calcitonin, the results would have been
more  favorable.  Therefore,  we intend to continue the  development of our oral
Calcitonin  product as a treatment of osteoporosis,  and have begun  discussions
with potential  licensees in the U.S. and other countries.  In addition,  due to
the  termination  of the Pfizer  agreement,  we no longer have  restrictions  on
selling bulk Calcitonin.

     We have filed patent  applications  for our oral  formulation in the United
States and in numerous foreign countries. In 1999, we received a U.S. patent for
our basic technology  covering the oral delivery of Calcitonin for the treatment
of osteoporosis. In 2000, we received a U.S. patent extending this protection to
the oral delivery of other peptides.

     There are risks that we will not be successful  in licensing  this product,
that a safe and effective  oral product will not be developed,  that we will not
be successful in obtaining  regulatory  approval of an oral

                                       28



Calcitonin  product,  and that we will not succeed in  developing,  producing or
marketing an oral Calcitonin product.

Development of a Nasal Calcitonin Product

     A major  pharmaceutical  company  received  FDA  approval  in 1995  for the
marketing of a nasal spray Calcitonin product,  which has substantially enlarged
the U.S.  market for  Calcitonin.  During 1999, we completed  preliminary  human
studies for our proprietary nasal Calcitonin  product.  A patent application for
the  product  was  filed  in  February   2000.  In  January  2000  we  filed  an
Investigational  New Drug Application with the FDA to begin human testing of our
nasal product as a treatment for  osteoporosis.  In February 2000, we began U.S.
human  studies.  In  December  2000,  we  successfully  completed  a human study
demonstrating  similar blood levels  between our product and that of an existing
nasal Calcitonin  product.  We have successfully  completed a second human study
which  showed a rapid  and  persistent  reduction  in bone loss as  measured  by
several  accepted blood markers.  A substance in the bloodstream  which measures
the rate of bone loss in the tested subjects decreased by an average of over 40%
in the first month of the study,  and that reduction was  maintained  throughout
the three-month  dosing period during which the measurements  were taken. We are
seeking to license our nasal Calcitonin  product in the U.S. and other countries
for the  treatment of  osteoporosis.  However,  we may not be  successful in our
efforts to conclude a license agreement,  to obtain governmental approval of our
nasal Calcitonin product, or to manufacture and sell the product.

Collaborative Research Programs

     We are currently engaged in two collaborative research programs:

     o    Rutgers  University  College  of  Pharmacy  continues  to  study  oral
          delivery of Calcitonin and other peptides.

     o    We are in  collaboration  with Yale  University,  to  investigate  new
          applications for various peptides,  including Calcitonin  gene-related
          peptide.  In 1996,  we reported  that this  peptide  accelerated  bone
          growth and  prevented  bone loss in an animal model  system.  However,
          this  peptide  may not have the same  effect in humans.  We may not be
          successful  in  developing,  manufacturing  or marketing any resulting
          product.

Patents and Proprietary Technology

     We have filed a number of  applications  for U.S.  patents  relating to our
proprietary peptide  manufacturing process and our technology for oral delivery.
To date, the following six U.S. patents have issued:

     o    Immunization By Immunogenic Implant, a method for producing antibodies
          for developing diagnostic medical tests

     o    two  patents  related  to the  Alpha-Amidation  Enzyme  and its use in
          manufacturing peptides

     o    a patent covering an improvement in our manufacturing technology

     o    two patents covering oral delivery of peptides

     Other  applications  are  pending.  We also have made  filings in  selected
foreign  countries,  and numerous  foreign  patents have  issued.  However,  our
pending  applications  may not issue as patents  and our issued  patents may not
provide us with significant competitive advantages. Furthermore, our competitors
may independently develop or obtain similar or superior technologies.

     Although  we believe our patents  and patent  applications  are valid,  the
repeal of one or more of our key patents could have a significant adverse effect
upon  our  business.  Detecting  and  proving  infringement  generally  is  more
difficult with process patents than with product patents. In addition, a process
patent's  value is  diminished  if others have  patented the product that can be
produced  using the process.  Under

                                       29



these circumstances, we would require the cooperation of, and likely be required
to share royalties with, the patent holder or its  sublicensees in order to make
and sell the product.

     In some  cases,  we rely on trade  secrets to protect our  inventions.  Our
policy is to include confidentiality provisions in all research contracts, joint
development  agreements and consulting  relationships that provide access to our
trade secrets and other  know-how.  However,  there is a risk that these secrecy
obligations  could  be  breached  causing  us  harm.  To the  extent  licensees,
consultants or other third parties apply technological information independently
developed  by them or by others to our  projects,  disputes  may arise as to the
ownership rights to information, which may not be resolved in our favor.

Employees

     As of November  30, 2001 we had 63  full-time  employees.  Twenty-one  were
engaged in research,  development and regulatory activities,  30 were engaged in
production  activities  and  12  were  engaged  in  general  and  administrative
functions.  Eight of our employees hold Ph.D. degrees. Our employees are experts
in  molecular  biology,  including  DNA  cloning,   synthesis,   sequencing  and
expression;  protein  chemistry,  including  purification,  amino acid analysis,
synthesis and  sequencing of proteins;  immunology,  including  tissue  culture,
monoclonal  and polyclonal  antibody  production  and  immunoassay  development;
chemical engineering;  pharmaceutical production; quality assurance; and quality
control.  None of our employees is covered by a collective bargaining agreement.
Warren P. Levy,  President and Ronald S. Levy,  Executive Vice  President,  both
executive officers and directors, have signed employment agreements with us.

Research and Development

     We have established a multi-disciplinary research team to adapt proprietary
amidation,   biological   production  and  oral  delivery  technologies  to  the
development of  proprietary  products and  processes.  Approximately  82% of our
employees  are  directly  engaged  in  activities  relating  to  production  of,
regulatory  compliance for, and the research and  development of  pharmaceutical
products. We spent $11.5 million on research activities in 2000, $9.4 million in
1999, and $9.0 million in 1998.

Properties

     We  own  a  one-story   office  and  laboratory   facility   consisting  of
approximately  12,500 square feet. The facility is located on a 2.2 acre site in
Fairfield, New Jersey.

     Our 32,000  square foot cGMP  production  facility,  of which 18,000 square
feet are currently  being used for the  production of Calcitonin and can be used
for the production of other peptides,  was constructed in a building  located in
Boonton,  New Jersey.  We lease the facility under a ten-year  agreement,  which
began in February  1994.  We have two 10-year  renewal  options and an option to
purchase the facility.

Litigation

     In July  2000,  the Tail Wind  Fund,  Ltd.,  the  holder of  $2,000,000  in
principal amount of 5% convertible  debentures issued by Unigene to Tail Wind in
a private placement completed in June 1998, filed with the American  Arbitration
Association a demand for arbitration  against Unigene.  In its demand, Tail Wind
claimed  that  it was  owed,  as of June  30,  2000,  approximately  $3,400,000,
consisting  of  principal,  interest and  penalties,  resulting  from  Unigene's
default under various provisions of the debentures and related agreements. These
alleged  defaults  included  Unigene's  failure to redeem the  debentures  after
becoming  obligated  to do so, the  failure to pay  interest  when due,  and the
failure to pay  liquidated  damages  arising  from the  delisting of the Unigene
common stock from the Nasdaq National Market.  See "Management's  Discussion and
Analysis of Financial  Condition and Results of Operations -- Capital  Resources
and  Liquidity."  In July 2000,  Unigene  submitted to the American  Arbitration
Association  a statement  in which it denies the amount of Tail Wind's claim and
makes  certain

                                       30



counterclaims.  A hearing on the matter  before an  arbitrator  appointed by the
American Arbitration  Association was scheduled for June 2001. In June 2001, the
arbitration was postponed to allow Tail Wind and Unigene to engage in settlement
discussions.  The  outcome of these  negotiations  is  uncertain.  An  extremely
unfavorable  settlement  or  arbitration  ruling  could have a material  adverse
effect on Unigene.

     In July 2000, Reseau de Voyage Sterling, Inc. filed suit against Unigene in
the Supreme  Court of the State of New York.  Unigene  removed  this case to the
United  States  District  Court  for the  Southern  District  of New  York.  The
plaintiff,  which purchased from a third party a warrant to purchase one million
shares of Unigene common stock, alleges that Unigene breached a verbal agreement
with the plaintiff to extend the term of the warrant beyond its expiration date.
The  plaintiff  is seeking  damages of $2 million.  We believe that this suit is
completely without merit, and we will continue to vigorously contest the claim.

Committees of the Board of Directors

     The  Board  of  Directors  performs  several  important  functions  through
committees.  These  committees are made up of members of the Board of Directors.
Unigene's  by-laws  authorize  the formation of these  committees  and grant the
Board the  authority  to  prescribe  the  functions  of each  committee  and the
standards for  membership of each  committee.  The Board has the following  four
standing committees. The Board does not have a standing nominating committee.

     Audit  Committee.  The  responsibilities  of the  Audit  Committee  include
annually  recommending a firm of independent  public accountants to the Board to
act as our  auditors,  reviewing the scope of the annual audit with the auditors
in  advance,  and  reviewing  the  results of the audit and the  adequacy of our
accounting,  financial and operating controls.  The Audit Committee also reviews
our accounting and reporting  principles,  policies and practices;  and approves
fees paid to the auditors for audit and non-audit services.  The current members
of the Audit  Committee  are Messrs.  Allen  Bloom,  J. Thomas  August and Bruce
Morra.

     Compensation Committee.  The responsibilities of the Compensation Committee

                                       32



Director Compensation

     Directors  who are not  employees  receive an annual  retainer of $8,000 as
well  as a fee of  $1,000  for  each  Board  meeting  attended.  Mr.  Robert  F.
Hendrickson (who did not stand for re-election in 2001) and Dr. Allen Bloom were
the only  directors  who received  such fees in 2000.  Board members do not earn
additional compensation for service on a committee.

     Under the Director Stock Option Plan,  each person elected to the Board who
is not an employee  receives,  on the date of his initial  election,  an initial
option to purchase  21,000 shares of Unigene  common  stock.  On May 1st of each
year,  each  non-employee  director  receives an  additional  option to purchase
10,000  shares  of  Unigene  common  stock if he has  served  as a  non-employee
director  for at least six months  prior to the grant  date.  Each  option has a
ten-year  term and the  exercise  price is equal to the market  price of Unigene
common  stock on the  date of the  grant.  Each  initial  option  vests in equal
installments of 1/3 over a period of three years,  commencing on the date of the
grant, and each additional option vests in its entirety on the first anniversary
of the grant. If the director's  service as a non-employee  director  terminates
prior to the expiration of the option term, the options will remain  exercisable
for a 90-day period following  termination of service,  except if a non-employee
director resigns due to disability,  the options will remain exercisable for 180
days following termination, and if a non-employee director dies while serving as
a director,  or within 90 days following termination of service (180 days in the
case of disability),  the options will remain exercisable for 180 days following
the person's death.  After such period,  the options will terminate and cease to
be exercisable.

Employment Agreements

     Unigene entered into an employment  agreement,  effective  January 1, 2000,
with Dr. Warren P. Levy for an initial term of two years.  Under the  agreement,
Dr. Levy serves as President and Chief Executive  Officer at an annual salary of
$160,000 for the first year of the  agreement.  The  Compensation  Committee has
discretion to approve salary increases beyond this first year.

     Unigene entered into an employment  agreement,  effective  January 1, 2000,
with Dr. Ronald S. Levy for an initial term of two years.  Under the  agreement,
Dr. Levy serves as Executive  Vice President at an annual salary of $155,000 for
the first year of the agreement.  Salary increases beyond this first year are at
the discretion of the Compensation Committee.

     Each agreement  provides that, after the first two-year term, the agreement
will be renewed on a  year-to-year  basis unless either party notifies the other
of the desire not to renew the agreement.  Either party must give this notice no
later than three months prior to the scheduled  termination date. Each agreement
also  provides  that,  if Unigene  terminates  the  employment  of the executive
without cause or the executive resigns for good reason,  which the executive has
a right to do upon a change of control of Unigene or a significant  reduction of
the  executive's  responsibilities  without  his  consent,  Unigene  will make a
lump-sum  severance  payment to the executive  equal to the salary that he would
have earned for the remaining  term of this  agreement,  if the  remaining  term
(either  the  initial  term or as  extended)  is more than one  year;  or if the
remaining term of the agreement  (either the initial term or as extended) is one
year or less, a lump-sum  payment equal to the executive's  then-current  annual
salary.

                                       33



Compensation Committee Interlocks and Insider Participation

     The Board of Directors determined executive compensation for 2000. Three of
the five  Board  members,  Warren P.  Levy,  Ronald  S.  Levy and Jay Levy,  are
executive officers. Jay Levy is the father of Warren and Ronald Levy.

     To satisfy the Company's short-term liquidity needs, Jay Levy, the Chairman
of the Board and an  officer  of  Unigene,  and  Warren  Levy and  Ronald  Levy,
directors and officers of the Company,  and another Levy family member from time
to time have made loans to the Company.  During the first  quarter of 2001,  Jay
Levy  loaned the  Company  $1,600,000  and Warren Levy and Ronald Levy each made
demand loans to the Company of $5,000.  During the second  quarter of 2001,  Jay
Levy made demand loans to the Company of $1,950,000. During the third quarter of
2001, Jay Levy made demand loans to the Company of an additional $1,475,000. Due
to the fact that Unigene did not make principal and interest payments on certain
loans when due,  interest on loans through March 4, 2001 increased an additional
5% per year and is calculated  on both past due  principal  and  interest.  This
additional  interest was approximately  $382,000,  and total interest expense on
all Levy loans was approximately $793,000 for the first nine months of 2001. The
Levys have waived all default provisions including additional interest penalties
due under these loans through  December 31, 2000. As of November 30, 2001, total
accrued interest on these loans was approximately $1,909,000 and the outstanding
loans by these  individuals  to the  Company,  classified  as  short-term  debt,
totaled $10,503,323 and consist of:

o    Loans from Jay Levy in the aggregate principal amount of $3,465,000,  which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill  Lynch  Margin  Loan Rate plus 5.25%  (11.25% at November 30, 2001)
     that are classified as short-term  debt. These loans were originally at the
     Merrill  Lynch  Margin  Loan Rate plus .25%.  These  loans are secured by a
     security  interest in the Company's  equipment and real  property.  Accrued
     interest on these loans at November 30, 2001 was approximately $1,041,000.

o    Loans  from  Jay  Levy in the  aggregate  principal  amount  of  $1,870,000
     evidenced by term notes maturing  January 2002, and bearing interest at the
     fixed rate of 11% per year.  These loans were originally at 6%. These loans
     are secured by a security  interest  in all of  Unigene's  equipment  and a
     mortgage on Unigene's real property. The terms of the notes require Unigene
     to make  installment  payments  of  principal  and  interest  beginning  in
     November 1999 and ending in January 2002 in an aggregate  amount of $72,426
     per month. No installment payments have been made to date. Accrued interest
     on these loans at November 30, 2001 was approximately $377,000.

o    Loans from Jay Levy in the aggregate  principal  amount of $4,650,000 which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill Lynch Margin Loan Rate plus .25%,  (6.25% at November 30, 2001) and
     are  classified  as  short-term  debt and which are  secured  by a security
     interest  in certain of our  patents.  Accrued  interest  on these loans at
     November 30, 2001 was approximately $137,000.

o    Loans from Warren Levy in the aggregate  principal amount of $260,000 which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill  Lynch  Margin Loan Rate plus 5.25%  (11.25% at November  30, 2001)
     that are classified as short-term  debt. These loans were originally at the
     Merrill Lynch Margin Loan Rate plus .25%. An additional  loan in the amount
     of $5,000 bears interest at the Merrill Lynch Loan Rate plus .25% (6.25% at
     November 30, 2001) and is classified as  short-term  debt.  These loans are
     secured by a secondary  security  interest in the  Company's  equipment and
     real  property.  Accrued  interest on these loans at November  30, 2001 was
     approximately $178,000.

o    Loans from Ronald Levy in the aggregate  principal amount of $248,323 which
     are evidenced by demand notes bearing a floating interest rate equal to the
     Merrill  Lynch  Margin Loan Rate plus 5.25%  (11.25% at November  30, 2001)
     that are classified as short-term  debt. These loans were originally at the
     Merrill Lynch Margin Loan Rate plus .25%. An additional  loan in the amount
     of $5,000  bears  interest at the Merrill  Lynch Margin Loan Rate plus .25%
     (6.25% at November 30, 2001) and is classified as  short-term  debt.  These
     loans  are  secured  by a  secondary  security  interest  in the  Company's
     equipment and real  property.  Accrued  interest on these loans at November
     30, 2001 was approximately $176,000.

                             Principal Stockholders

     The following table shows  information as of November 30, 2001,  concerning
the beneficial ownership of Unigene common stock by each of Unigene's directors,
each executive officer of Unigene listed in the Summary  Compensation Table, and
all directors and executive officers of Unigene as a group and each other person
known by Unigene to be the beneficial  owner of more than 5% of Unigene's common
stock.

     The  ownership  percentages  listed on the  table  are based on  50,316,544
shares of Unigene common stock  outstanding as of November 30, 2001.  Beneficial
ownership is  determined  in  accordance  with the rules of the  Securities  and
Exchange Commission.  A person generally is deemed to be the beneficial owner of
shares over which he has either voting or investment  power.  Shares  underlying
options that are currently  exercisable,  or that will become exercisable within
60 days, are deemed to be beneficially  owned by the person holding the options,
and are deemed to be  outstanding  for the purpose of computing  the  beneficial
ownership  percentage of that person,  but are not  considered to be outstanding
for the purpose of computing the ownership percentage of any other person.

     Except as  otherwise  noted,  the persons and the group  identified  in the
table have sole voting and sole investment  power with respect to all the shares
of Unigene common stock shown as beneficially owned by them. Except as otherwise
indicated,  the address of each  beneficial  owner  listed  below is c/o Unigene
Laboratories, Inc., 110 Little Falls Road, Fairfield, New Jersey 07004.

                              Plan of Distribution

     We are  registering  the  shares  of  our  common  stock  covered  by  this
prospectus on behalf of the selling stockholders. The purpose of this prospectus
is to permit the selling  stockholders,  if they desired,  to dispose of some or
all of the  shares  at  the  times  and at the  prices  as  they  determine  are
appropriate.  Whether sales will be made,  and the timing and amount of any sale
made, is within the sole discretion of the selling stockholders.  All references
in the section to selling  stockholders include donees and pledgees that receive
any of the shares covered by this prospectus from the named selling stockholders
by donation or pledge.

     Our common stock  covered by this  prospectus  may be offered for sale from
time to time by the selling  stockholders 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 those methods of sale, at
prices then prevailing,  at prices related to prevailing prices or at negotiated
prices.  Methods of distribution may include,  without  limitation:  (a) a block
trade in which a  broker-dealer  will attempt to sell our 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
the  broker-dealer  for its own  account  under 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 to describe a
specific plan of distribution.

     As part of a  distribution  of our common stock or  otherwise,  the selling
stockholders may enter into hedging  transactions  with  broker-dealers or other
financial  institutions.  As part of the transactions,  those  broker-dealers or
other  financial  institutions  may engage in short sales of our common stock in
the course of hedging the positions  they assume with the selling  stockholders.
The selling  stockholders may also sell our common stock short and redeliver the
shares to close out the short positions. The selling stockholders may also enter
into  options  or other  transactions  with  broker-dealers  or other  financial
institutions  that  require  the  delivery  to the  broker-dealer  or  financial
institution  of our common stock  covered by this  prospectus,  which shares the
broker-dealer  or other financial  institutions may resell under this prospectus
(as appropriately  amended or supplemented to reflect these  transactions).  The
selling   stockholders   also  may  pledge  the  shares  registered  here  to  a
broker-dealer  or  other  financial   institution  and,  upon  a  default,   the
broker-dealer  or other  financial  institution  may effect sales of our pledged
common stock under this prospectus (as appropriately  supplemented or amended to
reflect  these  transactions).  In addition,  any of our 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 under this prospectus.

     Brokers,  dealers  or  agents  may  receive  compensation  in the  form  of
commissions,  discounts or concessions from the selling  stockholders in amounts
to be negotiated  in connection  with sales.  The selling  stockholders  and any
broker or dealer  that acts in  connection  with the sale of the  shares  may be
deemed to be  "underwriters"  within the meaning of the Securities  Act, and any
commission received by a broker or dealer and any profit realized by a broker or
dealer on the  resale  of any  shares as  principal  may be deemed  underwriting
discounts or commissions under the Securities Act.

     All costs,  expenses and fees incurred upon the  registration of our common
stock will be borne by us.  Commissions,  discounts and transfer  taxes, if any,
attributable  to the  sales of our  common  stock  will be borne by the  selling
stockholders.

     We have agreed to supply the selling stockholders with the number of copies
of this prospectus as they may reasonably request.  Each selling stockholders is
responsible  for  complying  with  the  prospectus   delivery   requirements  in
connection  with any  offer  and sale by the  stockholder  of the  shares of our
common stock covered by this prospectus.

                                  Legal Matters

     The  validity  of the  shares  of  Unigene  common  stock  offered  by this
prospectus  has been  passed  upon for  Unigene  either by  Covington & Burling,
Washington,  D.C. or by Becker Ross Stone DeStefano & Klein, New York, New York.
The wife of James J. Ross,  an  attorney  who is of counsel to Becker Ross Stone

                                    Experts

     Unigene's  audited  financial  statements as of December 31, 2000 and 1999,
and for each of the years in the three-year period ended December 31, 2000, have
been  included  herein and in the  registration  statement in reliance  upon the
report of KPMG LLP,  independent  accountants,  appearing  elsewhere herein, and
upon the authority of KPMG LLP as experts in accounting and auditing.  The audit
report of KPMG LLP covering the December 31, 2000 financial  statements contains
an explanatory  paragraph that states that the Company's  recurring  losses from
operations and working  capital  deficiency  raise  substantial  doubt about the
entity's ability to continue as a going concern. The financial statements do not
include any adjustments that might result from the outcome of that  uncertainty.
Also, the report of KPMG LLP covering the December 31, 2000 financial statements
refers  to  a  change  in  the  method  of  revenue   recognition  for  up-front
non-refundable license fees in 2000.

INDEPENDENT AUDITORS' REPORT

The Stockholders and Board of Directors
Unigene Laboratories, Inc.:

We have audited the financial statements of Unigene Laboratories, Inc. as listed
in the accompanying index. These financial  statements are the responsibility of
the Company's  management.  Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of Unigene Laboratories,  Inc. as
of December 31, 2000 and 1999,  and the results of its  operations  and its cash
flows for each of the years in the three-year period ended December 31, 2000, in
conformity with accounting principles generally accepted in the United States of
America.

The  accompanying  financial  statements  have been  prepared  assuming that the
Company  will  continue  as a  going  concern.  As  discussed  in Note 17 to the
financial statements,  the Company has suffered recurring losses from operations
and has a working capital  deficiency  which raise  substantial  doubt about its
ability to continue as a going  concern.  Management's  plans in regard to these
matters are also  described in Note 17. The financial  statements do not include
any adjustments that might result from the outcome of this uncertainty.

As  discussed in Note 2 to the  financial  statements,  the Company  changed its
method of accounting for revenue recognition for up-front non-refundable license
fees in 2000.

                          NOTES TO FINANCIAL STATEMENTS
                  YEARS ENDED DECEMBER 31, 2000, 1999 AND 1998


1.   Description of Business

Unigene  Laboratories,  Inc. (the "Company"),  a biopharmaceutical  company, was
incorporated  in the State of Delaware in 1980.  The Company's  single  business
segment  focuses on  research,  production  and delivery of peptides for medical
use. The Company has  concentrated  most of its efforts to date on one product -
Calcitonin,  for the  treatment  of  osteoporosis  and  other  indications.  The
Company's  initial products will be injectable,  nasal and oral  formulations of
Calcitonin.  The  Company's  Calcitonin  products  require  clinical  trials and
approvals from regulatory agencies as well as acceptance in the marketplace. The
Company's  injectable  Calcitonin product has been approved for marketing in all
15-member  states of the European Union for the treatment of Paget's disease and
hypercalcemia  associated with  malignancy.  Through December 31, 2000, sales of
injectable  Calcitonin have not been significant.  Although the Company believes
its patents and patent  applications  are valid, the invalidation of its patents
or the failure of certain of its pending patent applications to issue as patents
could have a material  adverse  effect upon its business.  The Company  competes
with specialized  biotechnology  companies,  major  pharmaceutical  and chemical
companies and universities and research institutions.  Many of these competitors
have  substantially  greater resources than does the Company.  During 2000, 1999
and 1998,  almost all of the Company's  revenue was generated from one customer,
Pfizer (see Note 16). The Pfizer agreement was terminated in March 2001.

2.   Summary of Significant Accounting Policies & Practices

Segment  Information  -The Company is managed and operated as one business.  The
entire business is managed by a single management team that reports to the chief
executive  officer.  The Company does not operate  separate lines of business or
separate  business  entities  with  respect  to any of its  product  candidates.
Accordingly,  the Company does not prepare discrete  financial  information with
respect to separate  product  areas or by location and does not have  separately
reportable  segments as defined by Statement of Financial  Accounting  Standards
(SFAS) No.  131,  "Disclosures  about  Segments  of an  Enterprise  and  Related
Information."

Property,  Plant and  Equipment - Property,  plant and  equipment are carried at
cost.  Equipment  under  capital  leases are stated at the present  value of the
minimum lease payments. Depreciation is computed using the straight-line method.
Amortization  of equipment  under capital leases and leasehold  improvements  is
computed  over the  shorter of the lease term or  estimated  useful  life of the
asset. Additions and improvements are capitalized, while repairs and maintenance
are charged to expense as incurred.

Research and Development - Research and development  expenses  include the costs
associated  with internal  research and  development by the Company and research
and  development  conducted  for the  Company  by  outside  advisors,  sponsored
university-based  research partners,  and clinical study partners.  All research
and  development  costs  discussed  above are  expensed  as  incurred.  Expenses
reimbursed under research and development  contracts,  which are not refundable,
are recorded as a reduction to research and development expense in the statement
of operations.

Revenue Recognition - Research and development  contract revenues are recognized
based upon the successful  completion of various  benchmarks as set forth in the
individual agreements.  Commencing in 2000, non-refundable license fees received
upon  execution  of  license   agreements   where  the  Company  has  continuing
involvement  are  deferred  and  recognized  as  revenue  over  the  life of the
agreement.  Prior to the implementation of SAB 101,  non-refundable license fees
received  upon  execution  of  license  agreements  were  recognized  as revenue
immediately. Revenue from the sale of product is recognized upon shipment to the
customer.

In December  1999, the  Securities  and Exchange  Commission  staff issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB
101").  SAB 101  summarizes  certain of the staff's views in applying  generally
accepted accounting  principles to revenue  recognition in financial  statements
and specifically addresses revenue recognition in the biotechnology industry for
non-refundable technology access fees and other non-refundable fees. The Company
was required to adopt SAB 101, as amended, in the fourth quarter of 2000 with an
effective  date of January 1, 2000, and the  recognition of a cumulative  effect
adjustment  calculated  as of January 1, 2000.  The  Company  adopted SAB 101 in
2000,

                                      F-8



changing its revenue recognition policy for up-front licensing fees that require
services to be performed in the future from  immediate  revenue  recognition  to
deferral  of  revenue  with the  up-front  fee  recognized  over the life of the
agreement.  In 1997,  the  Company  recognized  $3,000,000  in  revenue  from an
up-front licensing fee from Pfizer. With the adoption of SAB 101, the Company is
now recognizing  this revenue over a 45 month period,  equivalent to the term of
its oral  Calcitonin  agreement  with Pfizer which was terminated in March 2001.
The Company  therefore  recognized a non-cash  cumulative  effect  adjustment of
$1,000,000  as of  January  1, 2000  representing  a revenue  deferral  over the
remaining 15 months of the agreement. The Company recognized $800,000 of revenue
in 2000 and $200,000 in revenue will be  recognized  in 2001 as a result of this
deferral.  The pro forma effects of retroactive  application of this new revenue
recognition  principle on net loss and related per share amounts,  for the years
ended  December  31,  2000,  1999  and 1998 are  presented  in the  accompanying
statements of operations.

Patents and Other Intangibles - Patent costs are deferred pending the outcome of
patent   applications.   Successful   patent  costs  are  amortized   using  the
straight-line  method over the lives of the patents.  Unsuccessful  patent costs
are expensed  when  determined  worthless.  As of December 31, 2000,  six of the
Company's  patents had issued in the U.S.  and  numerous  have issued in various
foreign  countries.   Various  other  applications  are  still  pending.   Other
intangibles are recorded at cost and are amortized over their  estimated  useful
lives. Accumulated amortization on patents and other intangibles is $186,000 and
$143,600 at December 31, 2000 and 1999, respectively.

Stock Option Plan - The Company  accounts for stock options  issued to employees
and directors in accordance with the provisions of Accounting  Principles  Board
(APB) Opinion No. 25,  "Accounting  for Stock Issued to Employees",  and related
interpretations. As such, compensation expense is recorded on fixed stock option
grants only if the current  market price of the  underlying  stock  exceeded the
exercise  price;  compensation  expense  on  variable  stock  option  grants  is
estimated until the measurement date. As permitted by SFAS No. 123,  "Accounting
for Stock-Based Compensation", the Company provides pro forma net income and pro
forma  earnings per share  disclosures  for  employee and director  stock option
grants  as if the  fair-value-based  method  defined  in SFAS  No.  123 had been
applied.  The  Company  accounts  for  stock  options  and  warrants  issued  to
consultants  on a fair value basis in accordance  with SFAS No. 123 and Emerging
Issues Task Force Issue No. 96-18,  "Accounting for Equity  Instruments That Are
Issued to Other Than  Employees for Acquiring,  or in Conjunction  with Selling,
Goods or Services."

Impairment of Long-Lived  Assets and  Long-Lived  Assets to Be Disposed Of - The
Company accounts for the impairment of long-lived  assets in accordance with the
provisions of SFAS No. 121,  "Accounting for the Impairment of Long-Lived Assets
and for  Long-Lived  Assets to Be Disposed  Of." This  Statement  requires  that
long-lived  assets  and  certain   identifiable   intangibles  be  reviewed  for
impairment  whenever  events  or  changes  in  circumstances  indicate  that the
carrying amount of an asset may not be recoverable.  Recoverability of assets to
be held and used is measured by a comparison of the carrying  amount of an asset
to the future undiscounted net cash flows expected to be generated by the asset.
If such assets are considered to be impaired, the impairment to be recognized is
measured  by the amount by which the  carrying  amount of the assets  exceed the
fair value of the assets.  Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to sell.

Net Loss per Share - The Company  computes and  presents  both basic and diluted
earnings per share ("EPS") on the face of the statement of operations. Basic EPS
is computed  using the  weighted  average  number of common  shares  outstanding
during the period being reported on. Diluted EPS reflects the potential dilution
that could occur if  securities  or other  contracts  to issue Common Stock were
exercised  or converted  into Common Stock at the  beginning of the period being
reported on and the effect was  dilutive.  The  Company's  net loss and weighted
average shares  outstanding  used for computing  diluted loss per share were the
same as that used for computing basic loss per share for each of the years ended
December 31, 2000, 1999 and 1998 because the Company's  convertible  debentures,
stock  options  and  warrants  were not  included in the  calculation  since the
inclusion of such potential shares (approximately  3,200,000 potential shares of
Common Stock at December 31, 2000) would be antidilutive.

Cash Equivalents - The Company considers all highly liquid securities  purchased
with an original maturity of three months or less to be cash equivalents.

Inventory -  Inventories  are stated at the lower of cost  (using the  first-in,
first-out method) or market.

Fair Value of Financial  Instruments - The fair value of a financial  instrument
represents  the amount at which the  instrument  could be exchanged in a current
transaction between willing parties, other than in a forced sale or liquidation.
Significant differences can arise between the fair value and carrying amounts of
financial instruments that are recognized at historical

                                      F-9



cost  amounts.  Given our  financial  condition  described in Note 17, it is not
practicable to estimate the fair value of our financial  instruments at December
31, 2000.

Use of Estimates - The  preparation of financial  statements in conformity  with
accounting  principles  generally  accepted  in the  United  States  of  America
requires  management to make estimates and assumptions  that affect the reported
amounts  of assets and  liabilities  and  disclosure  of  contingent  assets and
liabilities at the date of the financial  statements and the reported amounts of
revenues and expenses during the reporting  period.  Actual results could differ
from those estimates.

3.   Related Party Transactions

Notes payable - stockholders. Since 1995, Warren P. Levy, Ronald S. Levy and Jay
Levy each an officer and  director of the Company,  and another  member of their
family  (collectively,  the  "Levys"),  have  extended  loans to the Company for
working capital needs.  Each of the loans is evidenced by a promissory note that
sets  the  terms of the  loan.  The  variable  interest  rate on these  notes is
equivalent to the Merrill Lynch Margin Loan Rate plus .25%. The principal amount
is collateralized by security interests in the Company's  Fairfield,  New Jersey
plant and equipment and Boonton, New Jersey equipment.

During 1999,  Jay Levy loaned the Company  $1,500,000  evidenced by demand notes
bearing  interest  at 6% per year.  During the third  quarter of 1999,  Jay Levy
loaned the  Company an  additional  $370,000  evidenced  by term notes  maturing
January 2002 and bearing  interest at 6% per year,  and the $1,500,000 of demand
notes were converted  into 6% term notes maturing  January 2002. The Company has
granted Jay Levy a security  interest in all of its  equipment and a mortgage on
its real property to secure  payment of the term notes,  which are senior to all
notes  payable to Warren Levy and Ronald  Levy.  The Company is required to make
installment  payments on the term notes commencing in October 1999 and ending in
January  2002 in an  aggregate  amount of  $72,426  per  month.  No  installment
payments  were made during 1999 or 2000.  During  2000,  the Levys loaned to the
Company an additional  $1,733,323 in short-term  notes. As of December 31, 2000,
the  outstanding  loans by the Levys to Unigene,  all  classified  as short-term
debt, consisted of: joint loans in the aggregate principal amount of $2,873,323,
which are  evidenced by demand notes  bearing a floating  interest rate equal to
the Merrill  Lynch Margin Loan Rate  plus.25%  (9.875% at December 31, 2000) and
loans from Jay Levy in the aggregate principal amount of $1,870,000 evidenced by
term notes maturing  January 2002, and bearing  interest at the fixed rate of 6%
per  year.  During  2000,  $4,600 in  interest  was paid on these  loans.  As of
December 31, 2000,  accrued  interest on all Levy loans  totalled  approximately
$922,000.

Interest and principal payments required under these loans have not been made by
Unigene,  but the Levys have waived all default provisions  including additional
interest penalties due under these loans through December 31, 2000.

From January 1, 2001  through  March 30, 2001 the Levys loaned to the Company an
additional $1,610,000 of demand notes at the Merrill Lynch Margin Loan Rate plus
 .25%,  of which  $500,000  is secured by a security  interest  in certain of our
patents.

5.       China Joint Venture

In June 2000, we entered into a joint venture with  Shijiazhuang  Pharmaceutical
Group ("SPG"),  a pharmaceutical  company in the People's Republic of China. The
joint venture will  manufacture and distribute  injectable and nasal  Calcitonin
products in China (and possibly  other selected Asian markets) for the treatment
of osteoporosis. We own 45% of the joint venture and will have a 45% interest in
the joint venture profits and losses.  In the first phase of the  collaboration,
SPG will  contribute  its existing  injectable  Calcitonin  license to the joint
venture,  which will allow the joint  venture to sell our product in China.  The
joint  venture  will  need to  file a New  Drug  Application  in  China  for its
injectable and nasal products. In addition, the joint venture may be required to
conduct  brief  local human  trials.  If the  product is  successful,  the joint
venture  may  establish  a  facility  in  China  to fill  injectable  and  nasal
Calcitonin  products using bulk Calcitonin  produced at our Boonton,  New Jersey
plant. Eventually the joint venture may manufacture the bulk Calcitonin in China
at a new facility that would be  constructed  by the joint  venture.  This would
require  local  financing by the joint  venture.  The joint  venture has not yet
begun operations as of December 31, 2000.

Under  the  terms of the  joint  venture  with  SPG,  Unigene  is  obligated  to
contribute up to $405,000 in cash during 2001 and up to an  additional  $495,000
in cash within two years  thereafter.  However,  these amounts may be reduced or
offset by our share of joint venture  profits.  As of December 31, 2000, we have
not made any investments in the joint venture. In addition, Unigene is obligated
to pay to the Qingdao General Pharmaceutical Company an aggregate of $350,000 in
14 monthly  installment  payments  of $25,000 in order to  terminate  its former
joint venture in China,  of which $75,000 had been paid as of December 31, 2000.
We recognized the entire $350,000 obligation as an expense in 2000.

                                      F-11



6.   Convertible Debentures

In March 1996, the Company issued $3,300,000 of 9.5% Senior Secured  Convertible
Debentures  in  exchange  for a secured  loan of an equal  amount.  All of these
debentures  had been  converted into  approximately  2,924,000  shares of Common
Stock as of November 15, 1998, the due date of the debentures.

In March 1996, the Company completed a private placement of $9,080,000 aggregate
principal  amount  of 10%  Convertible  Debentures.  The  Company  received  net
proceeds of  approximately  $8.1  million as a result of this  placement.  These
debentures  were to mature  March 4, 1999,  but as of  December  31,  1998,  all
outstanding  10%  Debentures  have been  converted or redeemed in full.  Through
December 31, 1998,  $8,808,515  of principal  amount of these  debentures,  plus
approximately   $355,000  of  accrued   interest,   had  been   converted   into
approximately 4,838,000 shares of Common Stock. Due to restrictions on the total
number of shares which could be issued upon conversion of the 10% Debentures, in
October 1998 the Company  redeemed in cash an additional  $271,485 of principal,
and in connection  therewith paid to the holder $68,899 of accrued  interest and
$143,810 in redemption premiums,  for an aggregate payment of $484,194. The cost
of the redemption  premium of $143,810 was recorded as an extraordinary  loss in
1998.

In June 1998,  Unigene  completed a private placement of $4,000,000 in principal
amount of 5%  convertible  debentures  from which we  realized  net  proceeds of
approximately  $3,750,000.  The 5% debentures  were  convertible  into shares of
Unigene common stock. The interest on the debentures,  at Unigene's option,  was
payable in shares of Unigene common stock.  Upon conversion,  the holder of a 5%
debenture  was  entitled  to receive  warrants to purchase a number of shares of
Unigene  common stock equal to 4% of the number of shares  issued as a result of
the  conversion.  However,  the number of shares of Unigene common stock that we
are obligated to issue, in the aggregate,  upon  conversion,  when combined with
the shares  issued in payment of interest and upon the exercise of the warrants,
is limited to 3,852,500  shares.  After this share limit is reached,  Unigene is
obligated to redeem all 5%  debentures  tendered for  conversion at a redemption
price equal to 120% of the principal amount, plus accrued interest.  In December
1999,  Unigene was unable to convert  $200,000 in principal of the 5% debentures
tendered for  conversion  because the  conversion  would have exceeded the share
limit.  As a result,  we accrued,  as of December 31,  1999,  an amount equal to
$400,000 representing the 20% premium on the outstanding $2,000,000 in principal
amount of 5% debentures  that had not been  converted.  During 1999,  all of the
$2,000,000 in principal amount of 5% debentures were tendered for conversion and
therefore are  classified as a current  liability in the amount of $2,400,000 as
of December 31, 2000.

Through  December  31, 2000,  we issued a total of  3,703,362  shares of Unigene
common  stock  upon  conversion  of  $2,000,000  in  principal  amount of the 5%
debentures and in payment of interest on the 5%  debentures.  Also, we issued an
additional  103,032 shares of Unigene common stock upon the cashless exercise of
all of the 141,123 warrants issued upon conversion of the 5% debentures.

On January 5, 2000,  Unigene  failed to make the required  semi-annual  interest
payment on the outstanding 5% debentures.  As a result, the interest rate on the
outstanding  5%  debentures  has  increased  to 20% per  year.  The  semi-annual
interest  payments due July 5, 2000 and January 5, 2001 also have not been made.
As of December 31, 2000,  the accrued and unpaid  interest on the 5%  debentures
totaled approximately $467,000. In addition, due to the delisting of the Unigene
common stock from the Nasdaq  National  Market in October 1999,  Unigene  became
obligated  under a separate  agreement to pay the holder of the 5% debentures an
amount equal to 2% of the  outstanding  principal  amount of the  debentures per
month.  Unigene has not made any of these  payments to date, but has accrued the
amounts as an expense. As of December 31, 2000, the accrued and unpaid amount of
this penalty totaled approximately $617,000.

The holder of the 5% debentures has commenced an arbitration proceeding in which
the holder  claims  that it is  entitled,  as of June 30,  2000,  to payments in
respect  of the  5%  debentures  in  the  amount  of  approximately  $3,400,000,
consisting  of  principal,  interest and  penalties,  resulting  from  Unigene's
default under various provisions of the debentures and related agreements. These
alleged  defaults  included  Unigene's  failure to redeem the  debentures  after
becoming  obligated  to do so, the  failure to pay  interest  when due,  and the
failure to pay  liquidated  damages  arising  from the  delisting of the Unigene
common stock from the Nasdaq National Market. In July 2000, Unigene submitted to
the American  Arbitration  Association a statement in which it denies the amount
of Tail Wind's claim and makes  certain  counterclaims.  A hearing on the matter
before an  arbitrator  appointed  by the  American  Arbitration  Association  is
expected to occur in June 2001. The outcome of the  proceeding is uncertain.  An
extremely unfavorable ruling could have a material adverse effect on Unigene.

The Company in 1998 estimated the value of the beneficial conversion feature and
related  warrants  at the  issuance  of the 5%  Debentures  to be  approximately
$687,000.  Such  amount was  credited  to  additional  paid-in  capital  and was
amortized to

                                      F-12



interest  expense  over the  earliest  conversion  periods  using the  effective
interest  method  (approximately  $197,000  and  $490,000  for the  years  ended
December 31, 1999 and 1998, respectively).

7.   Fusion Capital Financing


On December 18, 2000,  and as amended  March 30,  2001,  Unigene  entered into a
common stock  purchase  agreement  with Fusion Capital Fund II, LLC, under which
Fusion has agreed to  purchase  up to  $21,000,000  in shares of Unigene  common
stock at the rate of $875,000  per month.  Fusion is  committed  to purchase the
shares over a  twenty-four  month  period,  subject to a six-month  extension or
earlier  termination at our discretion.  We may decrease this amount at any time
that the  price of our  common  stock is less than $15 per  share.  If our stock
price  equals or exceeds $4 per  share,  we have the right to require  Fusion to
purchase,  over a period of 60 days, up to the full remaining portion of the $21
million  commitment.  However,  Fusion's  commitment  does  not  begin  until  a
registration  statement covering the resale of the shares purchased by Fusion is
declared effective by the Securities and Exchange Commission.  We cannot predict
when or if the  SEC  will  declare  our  registration  statement  effective.  In
addition, Unigene must continue to satisfy its requirements that are a condition
to Fusion's  obligation  including:  the continued  effectiveness of the related
registration  statement, no default or acceleration of any obligations in excess
of $1,000,000,  no insolvency or bankruptcy  proceedings,  continued  listing of
Unigene common stock on the OTC Bulletin Board, and we must avoid the failure to
meet the maintenance  requirements for listing on the Nasdaq SmallCap Market for
a period of 10  consecutive  trading  days or for more than an  aggregate  of 30
trading days in any 365-day period.  The selling price per share is equal to the
lesser of: the lowest sale price of our common stock on the day of submission of
a purchase notice by Fusion;  the average of any five closing sale prices of our
common stock,  selected by Fusion,  during the 15 trading days prior to the date
of  submission  of a  purchase  notice by Fusion;  or $15.  In  addition  to the
2,000,000 shares and five-year  warrants to purchase  1,000,000 shares of common
stock at an  exercise  price of $.50 per  share  that we  issued to Fusion as of
March 30, 2001 as compensation  for its  commitment,  the Board of Directors has
authorized the issuance and sale to Fusion of up to 6,000,000  shares of Unigene
common stock in connection with the financing transaction. We may be required to
obtain the  approval  of  Unigene  stockholders  to an  amendment  to  Unigene's
certificate of  incorporation  increasing the number of shares of Unigene common
stock  that the  Company  is  authorized  to  issue  in order to issue  and sell
additional shares to Fusion.

In December  2000, the Company  issued a five-year  warrant to purchase  373,002
shares of Unigene common stock to its investment  banker as a fee for the Fusion
financing  agreement.  The warrant  has an  exercise  price of $1.126 and a fair
value of $327,000 using the  Black-Scholes  pricing model. The fair value of the
warrant has been deferred pending the closing of the Fusion financing.  When the
registration  statement for the financing is declared effective,  these deferred
offering  costs  will  be  charged  to  additional   paid-in  capital.   If  the
registration statement is not declared effective, or the offering is terminated,
these deferred offering costs will be charged to operations.

services  rendered.  Through December 31, 2000, an aggregate of 322,000 of these
warrants have been exercised and 132,000 remain unexercised.

In October 1996, the Company completed a private placement of 4,218,804 Units at

exercisable  to purchase  one share of Common  Stock) and (iii) one quarter of a
Class D Warrant  (each  whole Class D Warrant was  exercisable  to purchase  one
share of Common  Stock).  The Class C Warrants and the Class D Warrants each had

$3.00 per share,  for the purchase of 1,000,000  shares of Common  Stock.  These
warrants expired unexercised in October 1998. During 1996, another  consultant's
compensation  included  warrants to purchase a total of 400,000 shares of Common
Stock at exercise  prices ranging from $1.63 to $3.50 per share.  These warrants
expire in April 2001.

10,000  shares of Common  Stock.  Compensation  expense  recognized in 1997 as a
result of these  transactions  was  approximately  $131,000.  During  1998,  the
Company issued  warrants to purchase  5,000 shares of Common Stock,  expiring in
2003, to a consultant.  These warrants are  exercisable  at $2.38,  resulting in
1998  compensation  expense of  approximately  $7,000.  During 2000, the Company
issued warrants to purchase 150,000 shares of Common Stock, expiring in 2005, to
its investment  banker.  These warrants are exercisable at $2.66 and resulted in
2000 compensation expense of $220,000. The Company's investment bankers received

higher than the then market price of the Common Stock.

As of  December  31,  2000,  there are  warrants  outstanding,  all of which are
currently  exercisable,  to purchase an  aggregate  of 989,000  shares of Common
Stock at exercise prices ranging from $1.13 to $3.50 per share,  with a weighted

13.   Stock Option Plans

During  1994,  the  Company's  stockholders  approved  the  adoption of the 1994
Employee Stock Option Plan (the "1994 Plan").  All employees of the Company were
eligible to  participate  in the 1994 Plan,  including  executive  officers  and
directors who are employees of the Company.  The 1994 Plan terminated on June 6,
2000;  however,  1,729,965 options previously granted continue to be outstanding
and exercisable under that plan as of December 31, 2000.

At the Company's 1999 Annual Meeting, the stockholders  approved the adoption of
a 1999  Directors  Stock  Option Plan (the "1999  Plan") under which each person
elected to the Board after June 23, 1999 who is not an employee will receive, on
the date of his initial election,  an option to purchase 21,000 shares of Common
Stock.  In  addition,  on May 1st of each year,  commencing  May 1,  1999,  each
non-employee director will receive an option to purchase 10,000 shares of Common
Stock if he or she has served as a non-employee director for at least six months
prior to the May 1st grant.  Each option granted under the 1999 Plan will have a
ten-year term and the exercise  price of each option will be equal to the market
price of the Company's Common Stock on the date of the grant. A total of 350,000
shares of Common Stock are reserved for issuance under the 1999 Plan.

In  November  1999,  the Board of  Directors  approved,  subject to  stockholder
approval,  the  adoption of a new Stock Option Plan (the "2000 Plan") to replace
the 1994 Plan. All employees (including directors who are employees), as well as
certain consultants,  are eligible to receive option grants under the 2000 Plan.
Options  granted under the 2000 Plan have a ten-year term and an exercise  price
equal to the market price of the Common Stock on the date of the grant.  A total
of 4,000,000  shares of Common  Stock are  reserved for issuance  under the 2000
Plan.

In November  1999,  the Board  granted  under the 2000 Plan, to employees of the
Company,  stock  options to purchase an  aggregate  of 482,000  shares (of which
14,650 shares were subsequently  cancelled) of Common Stock at an exercise price
of $0.63 per share,  the market  price on the date of grant.  Each of the grants
was made subject to stockholder approval of the 2000 Plan. At the Company's June
6, 2000 Annual Meeting,  the stockholders  approved the 2000 Plan. In accordance
with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees",  the measurement  date for valuing the stock options for the purpose
of  determining  compensation  expense was June 6, 2000, the date of stockholder
approval.  The  market  price of the  Common  Stock on this date was  $2.093 per
share.  Therefore,  an  aggregate  of $683,733  will be charged to  compensation
expense over the vesting periods of the options, which vest in approximately 50%

                                      F-15



increments  on November 5, 2000 and  November  5, 2001.  The Company  recognized
$398,785  as  compensation  expense in 2000,  leaving a balance of  $284,948  as
deferred stock option compensation at December 31, 2000.

The fair value of the stock options  granted in 2000, 1999 and 1998 is estimated
at grant date using the  Black-Scholes  option-pricing  model with the following
weighted average assumptions: dividend yields of 0%; expected volatility of 103%
in 2000, 74% in 1999 and 63% in 1998; a risk-free interest rate of 4.7% in 2000,
6.4% in 1999 and 4.8% in 1998; and expected lives of 5 years in 2000 and 6 years
in 1999 and 1998.

During  1995,  the Company  granted to a consultant  options to purchase  10,000
shares of the Company's Common Stock, expiring in 2000, immediately  exercisable
at $1.44 per share.  These options were exercised in a cashless  exercise during
2000, resulting in the issuance of 4,175 shares of Common Stock.

14.   Income Taxes

As of  December  31,  2000,  the Company had  available  for federal  income tax
reporting purposes net operating loss carryforwards in the approximate amount of
$68,000,000,  expiring  from 2001 through  2020,  which are  available to reduce
future  earnings which would  otherwise be subject to federal  income taxes.  In
addition,  the Company has research and  development  credits in the approximate
amount of $2,500,000, which are available to reduce the amount of future federal
income taxes.  These credits  expire from 2001 through 2020. The Company has New
Jersey operating loss  carryforwards  in the approximate  amount of $23,300,000,
expiring from 2003 through 2007,  which are available to reduce future earnings,
which would  otherwise  be subject to state income tax. As of December 31, 2000,
approximately  $11,400,000  of these New  Jersey  loss  carryforwards  have been
approved for future sale under a program of the New Jersey Economic  Development
Authority (the "NJEDA").  In order to realize these  benefits,  the Company must
apply to the NJEDA each year and must meet various  requirements  for continuing
eligibility. In addition, the program must continue to be funded by the State of
New Jersey,  and there are limitations  based on the level of  participation  by
other  companies.  As a result,  future tax benefits  will be  recognized in the
financial  statements as specific sales are approved.  In the fourth quarters of
2000 and 1999, the Company realized $1,065,000 and $1,553,000,  respectively, of
tax benefits  arising from the sale of a portion of the Company's New Jersey net
operating  loss  carryforwards  that  had  previously  been  subject  to a  full
valuation allowance.

Given the  Company's  past  history of  incurring  operating  losses,  any gross
deferred  tax assets  that are  recognizable  under SFAS No. 109 have been fully
reserved.  As of December 31, 2000 and 1999,  the Company had gross deferred tax
assets of approximately  $29,000,000 and $26,000,000,  respectively,  subject to
valuation  allowances of $29,000,000 and  $26,000,000,  respectively.  The gross
deferred tax assets were  generated  primarily as a result of the  Company's net
operating  losses  and tax  credits.  The  Company's  ability  to use  such  net
operating  losses may be limited by change in control  provisions under Internal
Revenue Code Section 382.

15.   Employee Benefit Plan

The Company  maintains  a deferred  compensation  plan  covering  all  full-time
employees. The plan allows participants to defer a portion of their compensation
on a pre-tax basis  pursuant to Section  401(k) of the Internal  Revenue Code of
1986, as amended,  up to an annual maximum for each employee set by the Internal
Revenue Service. The Company's  discretionary  matching contribution expense for
2000,   1999  and  1998  was   approximately   $48,000,   $44,000  and  $43,000,
respectively.

16.    Research and Licensing Revenue

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.  In June 2000,  Pfizer Inc.  acquired
Warner-Lambert.  During  1997,  the  Company  received  $3 million for an equity
investment and $3 million for a licensing fee (see Note 2).  Several  milestones
were  achieved  during 1998,  resulting in milestone  revenue of $5 million.  In
1999, two pilot human studies for the Company's oral calcitonin formulation were
successfully concluded, resulting in milestone revenue totaling $5 million. Also
in 1999, the Company and Pfizer identified an oral calcitonin  formulation to be
used in the Phase I/II clinical study entitling the Company to milestone revenue
of an  additional  $4.5  million.  During 2000,  two  milestones  were  achieved
resulting in milestone revenue of $2 million.  Patient dosing for this study was
completed  in  December  2000.  Pfizer  analyzed  the  results of this study and
terminated the agreement in March 2001 citing scientific and technical reasons.

17.    Liquidity

The Company has incurred annual  operating  losses since its inception and, as a
result,  at  December  31,  2000 has an  accumulated  deficit  of  approximately
$75,378,000 and has a working capital  deficiency of approximately  $13,267,000.

                                      F-17



These factors raise substantial doubt about the Company's ability to continue as
a going concern. However, the financial statements have been prepared on a going
concern basis and as such do not include any adjustments  that might result from
the  outcome  of  this   uncertainty.   The  Company's  cash   requirements  are
approximately  $10 to 11 million  per year to operate its  research  and peptide
manufacturing facilities and develop its three Calcitonin products. In addition,
the Company has principal and interest  obligations  under its outstanding notes
payable  to  stockholders  and 5%  Convertible  Debentures  and its  obligations
relating to its current and former joint  ventures in China.  The Company's cash
requirements  related  to the 5%  Debentures  include  the  redemption  premium,
delisting  penalties  and  the  increased  interest  rate  described  in Note 6.
Management  is  actively  seeking   licensing  and/or  supply   agreements  with
pharmaceutical  companies for oral,  nasal and injectable forms of Calcitonin as
well as for other  oral  peptides.  With the  recent  termination  of our Pfizer
collaboration, we currently have no licenses for any of our products in the U.S.
We do not have sufficient financial resources to continue to fund our operations
at the current  level.  We had an operating  cash flow deficit of  $4,864,000 in
1998,  an  operating  cash flow deficit of  $1,400,000  in 1999 and for the year
ended  December 31,  2000,  an operating  cash flow deficit of  $3,382,000.  The
agreement  that we have  entered  into with Fusion  could  provide  Unigene with
funding beginning in the first half of 2001. See Note 7.

Under the  agreement  with Fusion,  after a  registration  statement is declared
effective by the SEC for the resale of the shares of Unigene  common stock to be
sold to Fusion,  Fusion will be required to purchase, at the then current market
price,  shares of Unigene  common stock at the rate of $875,000 per month over a
period of 24 months, provided that Unigene continues to satisfy the requirements
that  are a  condition  to  Fusion's  obligation.  The  Board of  Directors  has
authorized the sale to Fusion of up to 6,000,000 shares of Unigene common stock.
We anticipate that, in order to sell significantly in excess of 6,000,000 shares
to Fusion, it may be necessary to obtain stockholder approval of an amendment to
our  Certificate  of  Incorporation  to increase the number of shares of Unigene
common stock that we are authorized to issue. However, we cannot predict when or
if  the  SEC  will  declare  the  registration   statement  effective,   if  the
stockholders will approve an amendment to our Certificate of Incorporation or if
we will be able to meet the continuing requirements of the Fusion agreement.

If we do not receive any financing  from Fusion,  we will need to secure another
source of financing in order to satisfy our working capital needs,  which may be
unavailable  or the cost of which may be  prohibitively  expensive.  Should such
financing be unavailable or  prohibitively  expensive,  it will be necessary for
Unigene to curtail  significantly its operations or consider alternative uses of
its technology and manufacturing  capability  including the supply of Calcitonin
to other companies. Assuming we are able to raise additional capital through our
agreement with Fusion,  we still anticipate that we may need additional  capital
to implement  fully our business  plans.  We believe that satisfying our capital
requirements over the long term will require the successful commercialization of
our  Calcitonin  product or  another  peptide  product in the United  States and
abroad.  However,  it is uncertain  whether or not any of our  products  will be
approved or will be commercially  successful.  The commercialization of our oral
Calcitonin  product may require us to incur additional  capital  expenditures to
expand  or  upgrade  our  manufacturing  operations  to  satisfy  future  supply
obligations.  However, we cannot determine either the cost or the timing of such
capital expenditures at this time.

18.      Legal Matters

In addition to the arbitration proceedings discussed in Note 6, Reseau de Voyage
Sterling,  Inc.  (Reseau)  filed suit against the Company in July 2000.  Reseau,
which  purchased  from a third party a warrant to purchase one million shares of
Unigene common stock,  alleges that the Company  breached a verbal  agreement to
extend the term of the warrant  beyond its  expiration  date.  Reseau is seeking
damages of $2 million.  We believe that the suit is completely without merit and
we intend to vigorously contest the claim.

                           UNIGENE LABORATORIES, INC.
                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                               September 30, 2001
                                   (Unaudited)

NOTE A - BASIS OF PRESENTATION

The accompanying  unaudited condensed financial statements have been prepared in
accordance with accounting principles generally accepted in the United States of
America for interim financial information and with the instructions to Form 10-Q
and Article 10 of Regulation  S-X.  Accordingly,  they do not include all of the
information and footnotes required by generally accepted  accounting  principles
for complete financial statements. In the opinion of management, all adjustments
considered  necessary  for a fair  presentation  have been  included.  Operating
results for the nine-month  period ended  September 30, 2001 are not necessarily
indicative of the results that may be expected for the year ending  December 31,
2001.  For further  information,  please refer to our financial  statements  and
footnotes  thereto included in Unigene's annual report on Form 10-K for the year
ended December 31, 2000.

In December  1999, the  Securities  and Exchange  Commission  staff issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB
101").  SAB 101  summarizes  certain of the staff's views in applying  generally
accepted accounting  principles to revenue  recognition in financial  statements
and specifically addresses revenue recognition in the biotechnology industry for
non-refundable  technology access fees and other  non-refundable  fees.  Unigene
adopted SAB 101,  effective  January 1, 2000  changing  its revenue  recognition
policy for up-front  licensing fees that require services to be performed in the
future from  immediate  revenue  recognition  to  deferral  of revenue  with the
up-front fee recognized over the life of the agreement.

In 1997, we recognized $3,000,000 in revenue from an up-front licensing fee from
Pfizer.  With the  adoption of SAB 101, we have  recognized  this revenue over a
45-month  period,  equivalent to the term of our oral Calcitonin  agreement with
Pfizer which was  terminated in March 2001.  We therefore  recognized a non-cash
cumulative  effect adjustment of $1,000,000 as of January 1, 2000 representing a
revenue deferral over the remaining 15 months of the agreement.  We restated the
accompanying 2000 financial  statements for the cumulative effect adjustment and
recognized $200,000 of revenue in each of the quarters through March 31, 2001 as
a result of this deferral.

In June 1998,  the  Financial  Accounting  Standards  Board issued SFAS No. 133,
"Accounting for Derivative  Instruments and Hedging  Activities." This statement
establishes  accounting  and  reporting  standards for  derivative  instruments,
including certain derivative  instruments  embedded in other contracts,  and for
hedging  activities.  SFAS No. 133, as amended, is effective for our fiscal year
beginning  January 1, 2001.  The  adoption  of SFAS No. 133 had no effect on our
financial  position or results of operations,  as we do not engage in derivative
or hedging activities.

NOTE B - LIQUIDITY

Unigene has  incurred  annual  operating  losses since its  inception  and, as a
result,  at  September  30,  2001 has an  accumulated  deficit of  approximately
$85,000,000 and has a working capital  deficiency of approximately  $20,800,000.
These factors raise  substantial  doubt about our ability to continue as a going
concern. However, the financial statements have been prepared on a going concern
basis and as such do not  include  any  adjustments  that might  result from the
outcome of this  uncertainty.  Unigene's cash requirements are approximately $10
to 11  million  per year to  operate  its  research  and  peptide  manufacturing
facilities and develop its Calcitonin and other peptide products. In

                                      F-22



addition, Unigene has principal, interest and default interest obligations under
its outstanding notes payable to stockholders and its 5% debentures, in addition
to its  obligations  relating to its current and former joint ventures in China.
Unigene's cash requirements  related to the 5% debentures include the principal,
redemption  premium,   delisting  penalties  and  the  increased  interest  rate
described  in Note D.  Unigene  is  actively  seeking  licensing  and/or  supply
agreements with pharmaceutical companies for oral, nasal and injectable forms of
Calcitonin  as well as for other  oral  peptides.  With the  termination  of our
Pfizer  collaboration,  we currently have no licenses for any of our products in
the U.S. We do not have sufficient  financial  resources to continue to fund our
operations at the current level.  Under the agreement  with Fusion,  Unigene has
the contractual right to sell to Fusion,  subject to certain conditions,  at the
then current market price, on each trading day $43,750 of our common stock up to
an aggregate of $21,000,000  over a period of 24 months.  The Board of Directors
has  authorized  the sale to Fusion of up to 6,000,000  shares of Unigene common
stock.  See Note F. During the third  quarter of 2001,  Unigene  received  gross
proceeds  of  $476,000  from the sale of  1,437,000  shares of  common  stock to
Fusion.  From May 18, 2001,  through  September  30, 2001,  Unigene has received
approximately  $931,000  through the sale of 2,478,992 shares of common stock to
Fusion,  before cash  expenses of  approximately  $226,000.  Our sales of common
stock to Fusion have been below the  maximum  level  permitted  due to the share
price and trading volume of our common stock. As a result,  in the third quarter
of 2001, we borrowed an additional $1,475,000 from Jay Levy, the Chairman of the
Board, to fund our operations.

The extent to which we rely on Fusion as a source of financing  will depend on a
number of factors,  including the prevailing  market price and trading volume of
our common stock and the extent to which we are able to secure  working  capital
from other sources, such as licensing agreements or the sale of calcitonin, both
of which we are actively exploring. If we are unable to enter into a significant
revenue  generating license or other arrangement in the near term, we would need
either to secure  additional  sources of funding in order to satisfy our working
capital needs or significantly curtail our operations.  We also could consider a
sale or merger of the  company.  Should the  funding  we require to sustain  our
working capital needs be unavailable or prohibitively  expensive when we require
it,  the  consequence  would  be a  material  adverse  effect  on our  business,
operating results, financial condition and prospects.

We believe  that  satisfying  our capital  requirements  over the long term will
require the successful commercialization of our oral or nasal Calcitonin product
or another  peptide  product in the United  States and  abroad.  However,  it is
uncertain  whether  or not  any of our  products  will  be  approved  or will be
commercially  successful.  The commercialization of one or more peptide products
may require us to incur additional capital expenditures to expand or upgrade our
manufacturing  operations  to  satisfy  future  supply  obligations.  We  cannot
determine  either the cost or the timing of such  capital  expenditures  at this
time.

NOTE C - NOTES PAYABLE - STOCKHOLDERS

During the first  quarter of 2001,  Jay Levy,  the  Chairman of the Board and an
officer of  Unigene,  loaned to Unigene  $1,600,000  evidenced  by demand  notes
bearing  interest at the Merrill  Lynch  Margin Loan Rate plus .25%.  Due to the
fact that we did not make principal and interest payments when due, the interest
rate on $1,100,000 of these 2001 loans, as well as on $2,365,000 of prior demand
loans made to Unigene by Jay Levy,  has  increased an  additional 5% per year to
the Merrill Lynch Margin Loan Rate plus 5.25% (11.875% as of September 30, 2001)
and the interest rate on $1,870,000 of term notes  evidencing  loans made by Jay
Levy to Unigene has  increased  an  additional  5% per year from 6% to 11%.  The
increased rate is calculated on both past due principal and interest. During the
second  quarter of 2001,  Jay Levy  loaned to Unigene an  additional  $1,950,000
evidenced by demand notes bearing interest at the Merrill Lynch Margin Loan Rate
plus .25%.

                                      F-23



During the third  quarter  of 2001,  Jay Levy  loaned to  Unigene an  additional
$1,475,000  evidenced  by demand  notes  bearing  interest at the Merrill  Lynch
Margin Loan Rate plus .25% (6.875% as of September 30, 2001).

During the first  quarter  of 2001  Warren  Levy,  an officer  and  director  of
Unigene, loaned to Unigene $5,000 evidenced by a demand note bearing interest at
the Merrill  Lynch Margin Loan Rate plus .25% (6.875% as of September 30, 2001).
Due to the fact that we did not made  principal and interest  payments when due,
the  interest  rate on $260,000 of prior  demand loans made to Unigene by Warren
Levy has  increased an  additional  5% per year to the Merrill Lynch Margin Loan
Rate plus 5.25%  (11.875% as of  September  30,  2001).  The  increased  rate is
calculated on both past due principal and interest.

During the first  quarter  of 2001  Ronald  Levy,  an officer  and  director  of
Unigene, loaned to Unigene $5,000 evidenced by a demand note bearing interest at
the Merrill  Lynch Margin Loan Rate plus .25% (6.875% as of September 30, 2001).
Due to the fact that we did not make  principal and interest  payments when due,
the  interest  rate on $248,323 of prior  demand loans made to Unigene by Ronald
Levy has  increased an  additional  5% per year to the Merrill Lynch Margin Loan
Rate plus 5.25%  (11.875% as of  September  30,  2001).  The  increased  rate is
calculated on both past due principal and interest.

NOTE D - CONVERTIBLE DEBENTURES

In June 1998,  Unigene  completed a private placement of $4,000,000 in principal
amount of 5%  convertible  debentures  from which we  realized  net  proceeds of
approximately  $3,750,000.  The 5% debentures  were  convertible  into shares of
Unigene common stock. The interest on the debentures, at our option, was payable
in shares  of  Unigene  common  stock.  Upon  conversion,  the  holder of the 5%
debenture  was  entitled  to receive  warrants to purchase a number of shares of
Unigene  common stock equal to 4% of the number of shares  issued as a result of
the  conversion.  However,  the number of shares of Unigene common stock that we
were obligated to issue, in the aggregate,  upon conversion,  when combined with
the shares  issued in payment of interest and upon the exercise of the warrants,
was limited to 3,852,500  shares.  After this share limit was  reached,  Unigene
became  obligated  to redeem all 5%  debentures  tendered  for  conversion  at a
redemption price equal to 120% of the principal  amount,  plus accrued interest.
In December 1999,  Unigene was unable to convert $200,000 in principal of the 5%
debentures  tendered for conversion  because the conversion  would have exceeded
the share limit.  As a result,  Unigene  accrued,  as of December  31, 1999,  an
amount  equal  to  $400,000  representing  the 20%  premium  on the  outstanding
$2,000,000  in principal  amount of 5% debentures  that had not been  converted.
During 1999,  all of the  $2,000,000 in principal  amount of 5% debentures  were
tendered for conversion  and therefore are classified as a current  liability in
the amount of $2,400,000.

Through  September  30, 2001,  we issued a total of 3,703,362  shares of Unigene
common  stock  upon  conversion  of  $2,000,000  in  principal  amount of the 5%
debentures and in payment of interest on the 5%  debentures.  Also, we issued an
additional  103,032 shares of Unigene common stock upon the cashless exercise of
all of the 141,123 warrants issued upon conversion of the 5% debentures.

On January 5, 2000,  Unigene  failed to make the required  semi-annual  interest
payment on the outstanding 5% debentures.  As a result, the interest rate on the
outstanding  5%  debentures  has  increased  to 20% per  year.  The  semi-annual
interest  payments due July 5, 2000,  January 5, 2001 and July 5, 2001 also have
not been made. As of September 30, 2001, the accrued and unpaid  interest on the
5% debentures totaled approximately  $766,000. In addition, due to the delisting
of the Unigene common stock from the Nasdaq  National Market in October 1999, we
became obligated

                                      F-24



under a  separate  agreement  to pay the holder of the 5%  debentures  an amount
equal to 2% of the  outstanding  principal  amount of the  debentures per month.
Unigene has not made any of these  payments to date, but has accrued the amounts
as an expense.  As of September 30, 2001,  the accrued and unpaid amount of this
penalty totaled approximately $977,000.

The holder of the 5% debentures commenced an arbitration proceeding in which the
holder claimed that it is entitled,  as of June 30, 2000, to payments in respect
of the 5% debentures in the amount of  approximately  $3,400,000,  consisting of
principal,  interest and  penalties,  resulting  from  Unigene's  default  under
various  provisions  of the  debentures  and related  agreements.  These alleged
defaults  included  Unigene's  failure to redeem the  debentures  after becoming
obligated to do so, the failure to pay interest when due, and the failure to pay
liquidated  damages  arising from the delisting of the Unigene common stock from
the  Nasdaq  National  Market.  In  July  2000,  we  submitted  to the  American
Arbitration  Association  a  statement  in which we  denied  the  amount  of the
holder's claim and made certain counterclaims. A hearing on the matter before an
arbitrator appointed by the American  Arbitration  Association was scheduled for
June 2001. In June 2001,  the  arbitration  was postponed to allow Tail Wind and
Unigene to engage in settlement  discussions.  The outcome of these negotiations
is uncertain.  An extremely  unfavorable  settlement or arbitration ruling could
have a material adverse effect on Unigene.

NOTE F - FUSION CAPITAL FINANCING

On May 9, 2001,  Unigene  entered into a common stock  purchase  agreement  with
Fusion  Capital  Fund II,  LLC,  under  which  Unigene  has the right to sell to
Fusion,  subject to certain  conditions,  on each trading day during the term of
the  agreement  $43,750 of our common stock up to an  aggregate of  $21,000,000.
Fusion is committed to purchase the shares over a twenty-four  month period.  We
may decrease  this amount or terminate  the  agreement at any time. If our stock
price equals or exceeds $4.00 per share, for five (5) consecutive  trading days,
we have the right to increase the daily purchase amount above $43,750,  provided
that the  closing  sale  price of our stock  remains at least  $4.00.  Under the
agreement  with  Fusion,  Unigene  must  satisfy  the  requirements  that  are a
condition to Fusion's obligation including:  the continued  effectiveness of the
registration statement for the resale of the shares by Fusion, no default on, or
acceleration prior to maturity of, any payment  obligations of Unigene in excess
of $1,000,000, no insolvency or bankruptcy of the Company,  continued listing of
Unigene  common  stock on the OTC  Bulletin  Board,  and Unigene  must avoid the
failure to meet the maintenance requirements for continued listing on the Nasdaq
Small Cap Market for a period of 10 consecutive trading days or for more than an
aggregate of 30 trading days in any 365-day period.  Unigene did not meet all of
the  requirements  for  continued  listing on the Nasdaq Small Cap Market.  As a
result,  Fusion and Unigene  amended  their  agreement to change the  continuing
listing  requirements  to  those  of  the  OTC  Bulletin  Board.  Unigene  is in
compliance with the amended agreement.  The selling price per share to Fusion is
equal to the lesser of: the lowest sale

                                      F-25



price of our common  stock on the day of purchase  by Fusion,  or the average of
the lowest five closing sale prices of our common  stock,  during the 15 trading
days  prior to the date of  purchase  by Fusion.  We issued to Fusion  2,000,000
shares of common stock and a five-year  warrant to purchase  1,000,000 shares of
common  stock at an  exercise  price of $.50 per share as  compensation  for its
commitment.  Fusion has agreed not to sell the shares issued as a commitment fee
or the shares issuable upon the exercise of the warrant until the earlier of May
2003, or the termination or a default under the common stock purchase agreement.
In addition to the  compensation  shares,  the Board of Directors has authorized
the  issuance  and sale to Fusion of up to  6,000,000  shares of Unigene  common
stock.

In December  2000, we issued a five-year  warrant to purchase  373,002 shares of
Unigene  common stock to our investment  banker as a fee in connection  with the
Fusion  financing  agreement.  The warrant has an exercise price of $1.126 and a
fair value of $327,000  using the  Black-Scholes  pricing  model.  The 2,000,000
shares  issued to Fusion had a fair market value of  $1,000,000  and the warrant
for  1,000,000  shares  issued to Fusion had a fair value of $390,000  using the
Black-Scholes  pricing  model.  The value of these  warrants and shares had been
deferred  pending the closing of the Fusion  stock  offering.  The  registration
statement  for the stock  offering was declared  effective in May 2001 and these
deferred offering costs were charged to additional paid-in capital in the second
quarter of 2001.

From May 18, 2001 through September 30, 2001, Unigene has received approximately
$931,000 through the sale of 2,478,992 shares of common stock to Fusion,  before
cash expenses of approximately $226,000.

NOTE G - CHINA JOINT VENTURE

In  June  2000,   Unigene  entered  into  a  joint  venture  with   Shijiazhuang
Pharmaceutical Group ("SPG"), a pharmaceutical  company in the People's Republic
of China. The joint venture will manufacture and distribute injectable and nasal
Calcitonin products in China (and possibly other selected Asian markets) for the
treatment of osteoporosis and other  indications.  Unigene owns 45% of the joint
venture and will have a 45% interest in the joint venture profits and losses. In
the  first  phase  of  the  collaboration,  SPG  will  contribute  its  existing
injectable  Calcitonin license to the joint venture,  which will allow the joint
venture to sell our product in China. A New Drug  Application for its injectable
and nasal products has been filed in China.  In addition,  the joint venture may
be required to conduct brief local human trials.  If the product is  successful,
the joint venture may establish a facility in China to fill injectable and nasal
Calcitonin  products using bulk Calcitonin  produced at Unigene's  Boonton,  New
Jersey plant.  Eventually the joint venture may  manufacture the bulk Calcitonin
in China at a new facility that would be constructed by the joint venture.  This
would require local  financing by the joint  venture.  The joint venture has not
yet begun formal  operations as of September  30, 2001. We expect  operations to
commence in the first quarter of 2002.

Under the terms of the joint  venture  with SPG,  the  Company is  obligated  to
contribute up to $405,000 in cash during 2002 and up to an  additional  $495,000
in cash within two years  thereafter.  However,  these amounts may be reduced or
offset by our share of joint venture profits.  As of September 30, 2001, we have
not made any investments in the joint venture. In addition, Unigene is obligated
to pay to the Qingdao General Pharmaceutical Company an aggregate of $350,000 in
14 monthly  installment  payments  of $25,000 in order to  terminate  its former
joint venture in China, of which $80,000 had been paid as of September 30, 2001.
Unigene recognized the entire $350,000 obligation as an expense in 2000.

NOTE H - STOCK OPTION PLAN

In  November  1999,  the Board of  Directors  approved,  subject to  stockholder
approval,  the  adoption of a new Stock  Option Plan (the "New Plan") to replace
the 1994 Employee Stock Option Plan (the "1994 Plan"). All employees  (including
directors who are employees),  as well as certain  consultants,  are eligible to
receive  option  grants under the New Plan.  Options  granted under the New Plan
have a ten-year  term and an  exercise  price  equal to the market  price of the
common  stock on the date of the grant.  A total of  4,000,000  shares of common
stock are covered under the New Plan.

In November 1999, the Board granted under the New Plan, to employees of Unigene,
stock options to purchase an aggregate of 482,000 shares (of which 14,650 shares
were  subsequently  cancelled) of common stock at an exercise price of $0.63 per
share,  the  market  price on the date of  grant.  Each of the  grants  was made
subject to  stockholder  approval  of the New Plan.  At  Unigene's  June 6, 2000
Annual  Meeting,  the  stockholders  approved the New Plan. In  accordance  with
Accounting  Principles  Board  Opinion No. 25,  "Accounting  for Stock Issued to
Employees",  the measurement  date for valuing the stock options for the purpose
of  determining  compensation  expense was June 6, 2000, the date of stockholder
approval.  The  market  price of the  common  stock on this date was  $2.093 per
share.  Therefore,  an  aggregate  of $683,733  will be charged to  compensation
expense over the vesting periods of the options, which vest in approximately 50%
increments on November 5, 2000 and November 5, 2001. Unigene recognized $398,785
as  compensation  expense in 2000, and  compensation  expense of $256,455 in the
first nine months of 2001, leaving a balance of $28,493 as deferred stock option
compensation.

NOTE I - LEGAL MATTERS

In addition to the arbitration proceedings discussed in Note D, Reseau de Voyage
Sterling,  Inc. (Reseau) filed suit against Unigene in July 2000. Reseau,  which
purchased from a third party a warrant to purchase one million shares of Unigene
common  stock,  alleges that Unigene  breached a verbal  agreement to extend the
term of the warrant beyond its expiration date.  Reseau is seeking damages of $2
million.  We believe that the suit is completely  without merit and we intend to
continue to vigorously contest this claim.

NOTE J - NEW ACCOUNTING PRONOUNCEMENT

In July 2001, the FASB issued  Statement No. 142,  Goodwill and Other Intangible
Assets.  Statement  142 will require that  goodwill and  intangible  assets with
indefinite  useful  lives  no  longer  be  amortized,  but  instead  tested  for
impairment at least annually in accordance with the provisions of Statement 142.
Statement  142 will also require that  intangible  assets with  definite  useful
lives  be  amortized  over  their  respective  estimated  useful  lives to their
estimated  residual values,  and reviewed for impairment in accordance with SFAS
No. 121,  Accounting for the Impairment of Long-Lived  Assets and for Long-Lived
Assets to Be  Disposed  Of.  Unigene  is  required  to adopt the  provisions  of
Statement 142 effective January 1, 2002.

Upon adoption of Statement 142,  Unigene will be required to reassess the useful
lives and residual values of all intangible assets acquired in purchase business
combinations,  and make any necessary amortization period adjustments by the end
of the first  interim  period  after  adoption.  In  addition,  to the extent an
intangible asset is identified as having an indefinite useful life, Unigene will
be required to test the intangible  asset for impairment in accordance  with the
provisions of Statement 142 within the first interim period. Any impairment loss
will be measured as of the date of adoption  and  recognized  as the  cumulative
effect of a change in accounting principle in the first interim period.  Unigene
does not expect the adoption of the  pronouncement  to have a material effect on
its financial statements.

                                      F-27



In June 2001, the FASB issued Statement No. 143, Accounting For Asset Retirement
Obligations.  Statement  143 applies to legal  obligations  associated  with the
retirement  of tangible  long-lived  assets  that  result from the  acquisition,
construction,  or development  and/or the normal operation of a long-lived asset
for certain  obligations of lessees.  This Statement requires entities to record
the fair value of a liability for an asset  retirement  obligation in the period
incurred. The fair value of the liability is added to the carrying amount of the
associated  asset and this additional  carrying  amount is depreciated  over the
life of the asset.  The liability is accreted at the end of each period  through
charges to operating  expense.  If the  obligation is settled for other than the
carrying  amount of the liability,  the company will recognize a gain or loss on
settlement.  We are  required  to adopt the  provisions  of  Statement  No.  143
beginning  January 1, 2003.  We have not  determined  the  impact,  if any,  the
adoption of this  statement  will have on our  financial  position or results of
operations.

In August 2001, the FASB issued Statement No. 144, Accounting for the Impairment
or Disposal of Long-Lived Assets. This statement addresses financial  accounting
and  reporting  for the  impairment  or  disposal  of  long-lived  assets.  This
statement  supersedes  Statement  No.  121,  Accounting  for the  Impairment  of
Long-Lived  Assets and for  Long-Lived  Assets to Be Disposed Of. This Statement
establishes an accounting model for impairment or disposal of long-lived  assets
by sale.  Statement 144 is required to be adopted  beginning January 1, 2002. We
have not determined  the impact,  if any, the adoption of Statement No. 144 will
have on our financial position or results of operation.

Item 14.  Indemnification of Directors and Officers

     Article VI of the Registrant's By-laws requires the Registrant to indemnify
each of its  directors  and  officers to the extent  permitted  by the  Delaware
General  Corporation  Law  ("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  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
Delaware law to indemnify that person  against  expenses  (including  attorneys'
fees) actually and reasonably incurred in connection therewith.

     The  Registrant's  Certificate of  Incorporation  provides that no director
shall be liable to the Registrant or its  stockholders  for monetary damages for
breach of his fiduciary duty as a director.  However,  a director will be liable
for any breach of his duty of loyalty to the Registrant or its stockholders, for
acts or  omissions  not in good faith or  involving  intentional  misconduct  or
knowing  violation of law, any  transaction  from which the director  derived an
improper  personal  benefit,  or  payment  of  dividends  or  approval  of stock
repurchases or redemptions that are unlawful under Delaware law.

Item 15.  Recent Sales of Unregistered Securities

     Since  September  30,  1998,  Unigene  has  made  the  following  sales  of
securities that were not registered under the Securities Act of 1933, as amended
(the "Securities Act"):

     (1) In the quarter ended  December 31, 1998,  Unigene issued 448,834 shares
of Unigene common stock upon the  conversion of $502,694 in principal  amount of
Unigene's 9.5% Convertible Debentures. All of such shares were issued by Unigene
without  registration  in reliance on an exemption under Section 3(a) (9) of the
Securities Act.

     (2) In January 1999,  Unigene  issued 79,384 shares of Unigene common stock
as payment of  approximately  $101,000 in accrued interest on its 5% convertible
debentures due December 31, 2001, (the "5% Debentures"). All of such shares were
issued by Unigene without registration in reliance on an exemption under Section
4 (2) of the Securities Act.

     (3) In January 1999,  Unigene issued 164,102 shares of Unigene common stock
upon the conversion of $200,000 in principal amount of the 5% Debentures. All of
the shares  were  issued by  Unigene  without  registration  in  reliance  on an
exemption under Section 3(a)(9) of the Securities Act.

     (4) During the quarter ended June 30, 1999,  $1,000,000 in principal amount
of the 5% Debentures were converted into (a) 1,457,458  shares of Unigene common
stock and (b)  warrants,  expiring  April  through  June 2004,  to  purchase  an
aggregate of 58,298 shares of Unigene  common stock at exercise  prices  ranging
from $.78 to $1.15 per share.  All of such  shares and  warrants  were issued by
Unigene  without  registration in reliance on an exemption under Section 3(a)(9)
of the Securities Act.

     (5) In July 1999,  Unigene  issued 95,853 shares of Unigene common stock as
payment of approximately  $90,000 in accrued interest on the 5% Debentures.  All
of such  shares were issued by Unigene  without  registration  in reliance on an
exemption under Section 4 (2) of the Securities Act.

     (6) During the quarter  ended  December  31,  1999,  $800,000 of principal

Item 17.  Undertakings

(a)  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:

                                      II-6




         (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 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."

     (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.

(b) Insofar as indemnification  for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers and controlling  persons of the
Registrant pursuant to the foregoing  provisions,  or otherwise,  the Registrant
has been advised that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Securities Act
and is, therefore,  unenforceable. In the event that a claim for indemnification
against such  liabilities  (other than the payment by the Registrant of expenses
incurred or paid by a director,  officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

                                      II-7



                                   Signatures

     Pursuant to the requirements of the Securities Act of 1933, as amended, the
Registrant  has duly  caused  this  Registration  Statement  to be signed on its
behalf by the undersigned,  thereunto duly authorized, in Fairfield, New Jersey,
