                               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 {valuable therapeutic peptide hormones}[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 {a} patented {drug delivery} technology that has
been shown to deliver orally  {therapeutic  level} [medically useful amounts] of
{Calcitonin}  [various]  {an  amidated}  peptide[s]  into the  bloodstream.  Our
primary  focus  has  been on the  development  of  Calcitonin  products  for the
treatment of osteoporosis and other indications.

o    Injectable  Calcitonin.  Our injectable  Calcitonin product,  which has the
     trade name {FORCALTONINTMhas}  [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. Sales to date [of this product]
     have been minimal.

o    Nasal  Calcitonin.  {A} [In December  2000,  we  successfully  completed a]
     {clinical}  [human]  study  demonstrating   {equivalent  bio  availability}
     [similar  blood  levels]  between our  formulation  and that of an existing
     nasal Calcitonin product {was successfully  completed}.  {in December 2000}
     [We have  initiated a] second  {clinical}  [human]  study {is underway and}
     [with  results]  expected  {to  conclude} in {early}  [mid-]  2001.  We are
     seeking to license our nasal Calcitonin {formulation} [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  U.S.  Food  and  Drug
     {Adiminstration}  [Administration]  (FDA)  for the  conduct  of  {clinical}
     [human]  trials in the United States of our oral  Calcitonin  product [as a
     treatment for  osteoporosis].  [Pfizer began a]{A} Phase I/II [human] study
     {commenced}in  April 2000 [and] patient  dosing [for this study] {has been}
     [was] completed [in December 2000.] {and} [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.  ] {are being
     analyzed}

     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,
{clinical} [human] testing,  and marketing of products derived from our research
activities.  However,  we may,  in some  cases,  retain the  responsibility  for
{clinical} [human] testing and for obtaining the required  regulatory  approvals
for a particular product.

Unigene Common Stock

     Unigene  common  stock  trades on the OTC  Bulletin  Board under the symbol
"UGNE."

The Offering

         [On December 18, 2000,  Unigene  entered into an agreement  with Fusion
under which Fusion has committed to purchase from Unigene up to  $21,000,000  in
Unigene common stock at the rate of $875,000 per month.] Fusion Capital Fund II,
LLC,  the  selling  stockholder[,]  is  offering  for  sale  up  to  {7,331,009}
[9,000,000]  shares of Unigene common stock. The shares being offered consist of
up to 6,000,000  shares of common stock that Fusion has agreed to purchase  from
Unigene  and  {1,331,009}  [2,000,000]  shares of common  stock  [and  five-year
warrants,  for 1,000,000 shares of common stock,  exercisable at $.50 per share]
that  Unigene  has  {agreed  to} issue [d] to  Fusion  as  compensation  for its
purchase  commitment.  As of {February}[April 2], 2001, there were  {45,756,938}
[46,436,940]   shares  of  Unigene  common  stock  outstanding,   including  the
{1,331,009}  [2,000,000] shares that Unigene has {agreed to} issue [d] to Fusion
as  compensation  for its purchase  commitment  [but not including the 1,000,000
shares that are issuable upon the exercise of the warrant].

         The  number  of  shares  ultimately  offered  for sale [by  Fusion]  is
dependent  upon the number of shares  purchased  by Fusion.  This  number may be
affected by other factors more fully  described under the heading "The Financing
Transaction."

                                  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.  {Various}  [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,} [December 31] 2000, we had an accumulated  deficit of
{$71,619,000}  {$75,378,000}.  Our gross  revenues  for the {nine  months  ended
September 30, 2000 and the} years ended  December 31, [2000],  1999,  [and] 1998
{and  1997}  were  {$2,361,000,}  [$3,287,000,]  $9,589,000,   [and]  $5,050,000
{$3,003,000},  respectively.  [However, our revenues have not been sufficient to
sustain our operations.] These revenues {have} consisted principally of {upfront
payments and} milestone  payments  received in connection with {the licensing of
our proprietary  technology.} {However, our revenues have not been sufficient to
sustain our operations.}  [our terminated  license  agreement with Pfizer. As of
March 31, 2001, we have no significant  revenue generating license  agreements.]
As a result, during the same periods, we have incurred losses from operations of
{$7,892,000,}  [$11,385,000,]  $1,997,000,  [and] $6,060,000 {and  $10,098,000},
respectively.  Our net losses for {the nine months ended September 30, 2000 and}
the  years  ended  December  31,  [2000,]  1999,  [and]  1998  {and  1997}  were
{$8,711,000}  [$12,469,000]  $1,577,000,  [and]  $6,881,000  {and  $10,128,000},
respectively.  While our  injectable  Calcitonin  product has been  approved for
commercial sale in a number of European countries for the treatment of two minor
indications, we do not

                                       4


anticipate that sales for these indications will produce  significant  revenues.
We  believe  that the  profitability  of Unigene  will  require  the  successful
commercialization  of our Calcitonin  product or another  peptide product in the
United  States and  abroad.  {There is the risk  that}  Unigene  might  never be
profitable.

We will require additional financing to sustain our operations.


     At {September 30,} [December 31,] 2000, we had a working capital deficiency
of  [$13,267,000]  {$9,670,000}.  The independent  auditors' report for the year
ended December 31, [2000] {1999}, includes an explanatory paragraph stating that
{the  operating  losses,   accumulated   deficit}  [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  $6,278,000  in 1997,} 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 {nine months} [year] ended  {September 30,} [December 31] 2000, an operating
cash flow deficit of {$3,086,000} [$3,382,000]. We {believe that we} do not have
sufficient  financial  resources to fund our  operations  at the current  level.
Therefore,  excluding  any funding that we might  receive  from Fusion,  we need
additional  funds to continue our operations.  {The} [Our] agreement with Fusion
could  provide  {Unigene}  [us] with  sufficient  funding to sustain {its} [our]
operations for up to two years, beginning in the first {quarter} [half] of 2001.
However,  assuming we do not receive any funding  from  Fusion,  there is a risk
that we will not be able to generate revenues that are sufficient to sustain our
operations  and we would  require  additional  sources of  financing in order to
satisfy our working  capital needs,  which may be  unavailable or  prohibitively
expensive.  Should such financing be unavailable or prohibitively expensive when
we require it, we would not be able to sustain our working capital needs,  which
would have a material  adverse  effect on our  business,  operating  results and
financial condition.



         Even if we are  able to  access  $875,000  per  month  over the next 24
months,  available 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, {one result of the raising of additional capital
through}  [our  issuance of shares of common  stock to Fusion  under] the common
stock purchase agreement {with Fusion would be the issuance of additional shares
of our common stock. The issuance of additional shares to Fusion pursuant to the
common stock purchase  agreement could} [will] result in {substantial}  dilution
to {our} existing  stockholders.  We only have the right to receive $875,000 per
month under the common stock purchase agreement unless our stock price equals or
exceeds  $4.00 per share,  in which event  greater  amounts may be received.  In
addition,  the  agreement  may be terminated by Fusion in the event of a default
under the agreement. See "The Financing Transaction-Events of Default." Since we
have initially registered  6,000,000 shares in this offering,  the selling price
of our stock to Fusion  will have to average at least  $3.50 per share for us to
receive the maximum proceeds of $21,000,000  without  registering or issuing any
additional  shares.  We may need to seek  shareholder  approval to increase  the
total number of authorized  shares of our common stock.  {Sales} [We cannot sell
shares] of Unigene  common stock to Fusion {cannot begin until a} [until the SEC
declares  effective  the]  registration  statement  registering  the shares {for
resale by Fusion is declared effective by the SEC} [offered by this prospectus].
Unigene  cannot  predict  with [any]  certainty  if or when this will occur.  We
believe that  satisfying  our long-term  capital  requirements  will require the
successful  commercialization  of one  of our  peptide  products.  {There  is no
assurance}  [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.


         {Our}[We  have obtained  regulatory  approval in Europe for the sale of
our]  injectable  Calcitonin  product {has been approved for commercial  sale in
Europe}, 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.

                                       5



Food and Drug Administration  must approve the] commercial  manufacture and sale
of pharmaceutical  products in the U.S. {is subject to the approval of the U. S.
Food and Drug Administration.} Similar regulatory approvals are required for the
sale  of   pharmaceutical   products   outside  of  the  United   States.   {The
commercialization of our products requires} [We must conduct] further {clinical}
[human] testing {. These clinical trials must show }[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.  {in  order to  obtain  the  regulatory
approvals  required for commercial sale} If any of our products are approved for
commercial sale, {the product} [we] will need to {be manufactured}  [manufacture
the product] in commercial quantities at a reasonable cost in order for it to be
a successful product that will generate profits. {for us} 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 {grade} products.

     We believe that expanded consumer  acceptance of Calcitonin  pharmaceutical
products  depends on the development of {a consumer  accepted  delivery  system}
[more desirable  formulations.]  We {are currently  conducting} [have initiated]
{clinical}  [human] trials {in conjunction with Pfizer} to evaluate {an oral} [a
nasal] {delivery system for} Calcitonin  [product with final results expected in
mid-2001].  [Pfizer  recently  completed a human  trial for our oral  Calcitonin
product, but after analyzing the results it terminated our license agreement due
to scientific and technical reasons.  We disagree with Pfizer's  conclusions and
plan to seek 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.]  {This}  [In  addition,  we may  not be  able to
demonstrate the safety or effectiveness of our  products]{oral  delivery system}
{may not prove  successful}  in {clinical}  [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]  {this  delivery
system}  [products.]  Other  companies  may  develop  {oral or} other  {delivery
systems}  [products]  to compete  with or surpass any [nasal or] oral  {delivery
system} [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
{pharmaceutical grade} Calcitonin and other peptide[s] {hormones}. This facility
has been approved by European  regulatory  authorities  for the  manufacture  of
Calcitonin  for human  {pharmaceutical}  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 {will}
[may]  require  us to make  additional  expenditures  to expand or  upgrade  our
manufacturing  operations  {to satisfy our supply  obligations  under the Pfizer
license agreement.}  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 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.  {We have granted to Pfizer a worldwide  license to make,  use and
sell our oral  Calcitonin  products  in  exchange  for which we are  entitled to
receive  milestone  payments at various  stages in the  development  process and
royalties  on sales if the product is  successfully  commercialized.}  [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 {is in the early
stages of  development}  [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.  {have not
produced material revenues}


                                       6




         We intend to pursue additional  opportunities to license, or enter into
distribution   arrangements  for,  our  {technologies  for}  [oral,  nasal  and]
injectable  {and nasal  formulations  of} 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  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.

{Our production facility may be audited by the}

         [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 {guidelines}. These guidelines require
that {the} [we  conduct  our]  production  operation  {be  conducted}  in strict
compliance  with our  {written  protocols  for  reagent  qualification,  process
execution,  data  recording,  instrument  calibration  and  quality  monitoring}
[established rules for manufacturing and quality controls.] {The} [Any of these]
agencies  can  suspend  production  operations  and  product  sales if they find
significant  or  repeated   {deviations}   [changes]  from  the[se]  {protocols}
[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  {evolving}  [changing]  and  highly
competitive field. To date, Unigene has concentrated its {commercial} efforts on
one {compound}  [product] -- Calcitonin -- for treating  osteoporosis  and other
indications.  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.  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 {drug delivery technologies} [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.  {There  is a}  [We  face  the]  risk  that  any  of  our  pending
applications will not issue as patents.  {There is also a} [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

                                       7



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,  {there is a risk that these secrecy
obligations   will  be  breached  to  our   detriment.}   [other   parties  with
confidentiality    obligations   could   breach   their   agreements   {to   our
detriment}[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 {inherent in the } [a part of] {clinical} [human] testing, manufacturing and
{commercial use} [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.

     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.  The  outcome  of the
arbitration proceeding is uncertain.  An extremely unfavorable ruling could have
a material adverse effect on Unigene.


The market price of Unigene common stock may be highly {volatile} [unstable.]

     The market price of Unigene common stock has been and {is} [we]  expect{ed}
[it]  to  continue  to  be  highly  {volatile}  [unstable.]  Factors,  including
{announcements} [our announcement] of technological {innovations} [improvements]
[or] [announcements by] {us or} other companies,  regulatory matters,  [research
and development activities,] new or existing products or procedures, [signing or
termination of licensing  agreements,]  concerns  about our financial  position,
operating  results,  litigation,  resolution  of the  arbitration  involving our
outstanding  convertible  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

                                       8



and its  stockholders[,]  including [sales by] Fusion {pursuant to} [under] this
prospectus  and by the exercise and  subsequent  sale of Unigene common stock by
the holders of  [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 the Unigene common stock.


         We have {not}  [never] paid any cash  dividends  on the Unigene  common
stock {since our inception}  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.


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

     The Unigene common stock is traded on the OTC Bulletin  Board. As a result,
the  holders  of  Unigene  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  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 Unigene common stock to Fusion could cause substantial  dilution and
the sale of the  shares  acquired  by Fusion  could  cause the price of  Unigene
common stock to decline.

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


         All of the shares offered for sale by Fusion under this  prospectus are
freely tradeable.  However, Fusion has agreed that it will not sell or otherwise
transfer the {1,331,009} [2,000,000] commitment shares [ or the 1,000,000 shares
issuable  upon the exercise of its warrant  which we issued as of March 30, 2001
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  this   agreement  or  the  maturity  date  of  the  agreement   which  is
approximately two years from the date {hereof} [of this prospectus].  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  registered  in this
offering  will be sold over a period  of up to 24  months  from the date of this
prospectus. Depending upon market liquidity at the time, {a sale} [the resale by
Fusion] of shares  registered in this offering at any given time could cause the
trading price of the Unigene common stock to decline.  The sale [by Fusion] of a
substantial number of shares {of Unigene common stock under this offering, or }[
purchased from Unigene,  or the] anticipation of such sales,  could make it more
difficult for Unigene to sell equity or equity related  securities in the future
at a time and at a price that it might otherwise wish to effect sales.

                                       9



         If Fusion  purchased  the full amount of shares  purchasable  under the
common stock purchase agreement on the date of this prospectus, at a price equal
to {$1.44}  [$0.55],  the  closing  sale price of the  Unigene  common  stock on
{February  5}[April 2], 2001, Fusion would have been able to purchase a total of
{14,583,333}  [38,181,818] shares of our common stock. These shares,  along with
the {1,331,009} [2,000,000] shares [ and warrants for 1,000,000 shares of common
stock] that {will  be}[have  been] issued to Fusion as a commitment  fee,  would
represent  {26%} [48%] of our  outstanding  common  stock as of the date of this
prospectus.  {This} [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.  See  "The  Financing
Transaction-Purchase  of shares under the common stock purchase agreement" for a
table that shows the number of shares  issuable and potential  dilution based on
varying market prices. Although we have the right to suspend Fusion purchases if
the market  price of our  common  stock is below  $15.00  for three  consecutive
trading days, the financial condition of Unigene at the time may require Unigene
to {forgo}  [waive] its right to suspend  purchases  {notwithstanding}  [even if
there is] a decline in the market price. If the closing sale price of our common
stock prior to the first trading day of any 30-day period is at least $4.00,  we
have the right to  require  purchase  by Fusion of part or all of the  remaining
balance of the $21  million  during the next two 30-day  periods,  provided  the
closing  sale price of our common stock  during such 30-day  periods  remains at
least $4.00.


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


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


                           Forward-Looking Statements


     Various  statements  {made}  [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
{preclinical}  [animal]  and  {clinical}  [human]  testing,  the risk of product
liability and liability for human {clinical}  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.


                                 Use of Proceeds

         Unigene  will  not  receive  any of the  proceeds  from the sale of the
shares of Unigene common stock offered for sale by Fusion under this prospectus.
However,  we may receive up to $21,000,000  from the sale of our common stock to
Fusion under the agreement with Fusion.

                                 Dividend Policy

     Unigene has never paid a cash dividend on the Unigene 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] {1998} and 1999,
and for the years ended  December  31,  [2000,  1999 and 1998]  {1997,  1998 and
1999,}  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 certified public accountants.  The report of KPMG LLP covering these

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.  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 are now recognizing  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 recognized $800,000 in revenue in 2000
and will recognize $200,000 of revenue in 2001 as a result of this deferral.

The  quarterly  financial  data above has been  adjusted to reflect  retroactive
application of SAB 101,  Therefore,  in each of the first three quarters of 2000
we recognized  $200,000 in additional  revenue related to the cumulative  effect
adjustment.

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


     {The  following  discussion  should be read} [You should read the following
discussion] {in  conjunction}  [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.


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  is  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.

     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  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

                                       15

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"). 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  life  of its  oral
Calcitonin  license with Pfizer which was  terminated in March 2001. The Company
therefore  recognized a non-cash  cumulative  effect adjustment of $1,000,000 in
2000  representing a revenue  deferral over 15 months as of January 1, 2000. 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 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.


                                       16


Unigene has two consecutive ten-year renewal options under the lease, as well as
an option to purchase the facility.  During 2000, Unigene invested approximately
$519,000  in fixed  assets and  leasehold  improvements.  The  majority of these
expenditures  were  to  increase  Unigene's  analytical  testing   capabilities.
Currently,  we have no material commitments outstanding for capital expenditures
relating to either the Boonton facility or our office and laboratory facility in
Fairfield, New Jersey.

     At December 31, 2000,  Unigene had cash and cash equivalents of $17,000,  a
decrease of $666,000 from December 31, 1999.

     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 December 31, 2000, had an accumulated
deficit  of  approximately  $75,378,000  and a  working  capital  deficiency  of
approximately  $13,267,000.  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
the Unigene common stock.  The delisting of the common stock may have an adverse
effect on our ability to raise capital.

     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.  Unigene's 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, receiving regulatory approval for
its licensed products, and the sale of these products.

    In July 1997,  Unigene  entered into an agreement  under which it granted to
Warner-Lambert   Company  a  worldwide   license  to  use  our  oral  Calcitonin
technology.  In June 2000, Pfizer Inc acquired Warner-Lambert.  Through December
31, 2000, Unigene had received $3 million for an equity  investment,  $3 million
for a licensing  fee and  recognized  an aggregate of $16.5 million in milestone
revenue under the agreement. Pfizer conducted a Phase I/II human study which 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.  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 in Israel for its  injectable
product.  However,  these distribution  agreements have not produced significant
revenues.  In June 2000, Unigene entered into a joint venture agreement in China
with  Shijiazhuang  Pharmaceutical  Group ("SPG") to manufacture  and market our
injectable  and  nasal  products.  See  "Business  --  Strategy  -- China  Joint
Venture." We are actively seeking other licensing and/or supply  agreements with
pharmaceutical  companies for our injectable and nasal  Calcitonin  products and
for other  pharmaceutical  products that can be  manufactured  and/or  delivered
using  our  patented  technologies.  However,  we may not be  successful  in our
efforts to enter into any additional revenue-generating agreements.


                                       17

         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.  However, as of December 31, 2000,
we had not made any contributions to 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.

     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.  As of December
31, 2000,  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 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 additional interest 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.  See
"Business -- Litigation."


     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 February 2000, Jay Levy loaned us $300,000.  This
loan was repaid in April 2000. During the third and fourth quarters of 2000, Jay
Levy and another  family  member  loaned  Unigene an aggregate of  $1,655,000 in
demand  loans and Warren  Levy and Ronald Levy loaned  Unigene an  aggregate  of
$78,323  in demand  loans.


                                       18


As of December 31, 2000,  total accrued interest on these loans was $922,000 and
the outstanding loans by these  individuals to Unigene,  classifed as short-term
debt, totaled $4,743,323 and consisted of:

o loans from the Levys 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) that are
classified as short-term debt. These loans are secured by a security interest in
Unigene's equipment and/or real property.

o

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
6% per year. 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.

     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,  Jay Levy,  Warren Levy and
Ronald Levy loaned to us an  additional  $1,610,000  at the Merrill Lynch Margin
Loan Rate plus .25%,  of which  $500,000  is secured by a security  interest  in
certain of our patents. No interest on these loans has been paid.

    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 stockholders 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, 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.
Assuming  that all sales were to occur at the closing price on April 2, 2001, of
$.55, we would be able to raise approximately $3,300,000 through the sale of the
6,000,000 shares to Fusion.  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. Assuming we have an adequate number of shares of common stock to sell, we
stay in  compliance  with the  agreement,  and  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 first half of 2001.  See
"The Financing  Transaction." However, we cannot predict when or if the SEC will
declare the registration statement effective.


                                       19


     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.  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.  In
addition, the commercialization of our oral Calcitonin product may require us to
incur  additional  capital  expenditures to expand or upgrade our  manufacturing
operations.  However,  we cannot determine either the cost or the timing of such
capital expenditures at this time.

     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.

     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, we 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 our net  operating  losses and
tax credits.


Other

     The Unigene common stock has been delisted from the Nasdaq  National Market
System 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.

     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,  will be effective for our fiscal
year  beginning  January 1, 2001. We do not expect that the adoption of SFAS No.
133 will  have a  material  effect  on our  financial  position  or  results  of
operations.

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. We do not employ specific strategies,  such as the use of derivative
instruments or hedging, to manage our interest rate exposure. Unigene's interest
rate exposure on the 5%  convertible  debentures  has been affected by Unigene's
delisting from the Nasdaq  National  Market and failure to make the  semi-annual
interest payment in January 2000.

                                       20


Our 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 December 31, 2000.  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% convertible 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 December 31`,
2000.  Given  our  financial  condition  described  in  "Liquidity  and  Capital
Resources"  it is not  practicable  to  estimate  the  fair  value  of our  debt
instruments at December 31, 2000.

         convertible  debentures  has increased from 7% at December 31, 1999, to
         20%  beginning  January 5, 2000.  In addition,  due to the delisting of
         Unigene common stock from NASDAQ in 1999,  Unigene became  obligated to
         pay the  holder  of the 5%  debentures  an  amount  equal  to 2% of the
         outstanding principal amount of the debentures per month.


                                    Business

Overview


      Unigene is a biopharmaceutical company engaged in the research, production
and  delivery  of  {valuable  therapeutic  peptide  hormones}  [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 {a} patented {drug delivery} technology that has
been shown to deliver orally  {therapeutic  levels of} [medically useful amounts
of] {Calcitonin, an amidated} [ various] peptide[s],  into the bloodstream.  Our
primary  focus  has  been on the  development  of  Calcitonin  products  for the
treatment of osteoporosis and other indications.  We have the facilities and the
technology for  manufacturing  {pharmaceutical  grade}  Calcitonin in accordance
with cGMP and have an injectable Calcitonin product that is approved for sale in
the European Union [for two minor indications]. We are {continuing, directly and
through a licensee,} [also engaged in] the {clinical  testing} of oral and nasal
Calcitonin {formulations} [products.]



                                       22


Our Accomplishments

         Among our major accomplishments are:


     o Development of a Proprietary Peptide {hormone} Production Process. One of
our  principal  scientific  accomplishments  is our  success in  {combining  our
proprietary  amidation  process with our proprietary  bacterial  recombinant DNA
technology  to develop a}  [developing a highly  efficient  biotechnology-based]
peptide {hormone}  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 {various}  peptides
{hormones} with {diverse  therapeutic} [various medical]  applications.  Many of
these  {hormones}  [peptides]  cannot  be  produced  at  a  reasonable  cost  in
sufficient  quantities  for  {clinical}  [human]  testing or  commercial  use by
currently available production processes. Using our proprietary process, we have
produced  laboratory-scale  quantities of various peptide[s] {hormones}. We have
constructed and are operating a manufacturing facility employing this process to
produce Calcitonin.

     o Development  of {a}  Proprietary  {Oral  Delivery}  Technology  [for Oral
Delivery].  We have also developed and patented {an oral delivery technology} [a
formulation]  that  has  successfully  delivered  [orally]  Calcitonin  into the
bloodstream  of  human  subjects.   {The  formulation  has  been}  [We  and  our
collaborators  have] shown in repeated  {clinical}  [human]  studies  [that this
formulation]  regularly  {to deliver}  [delivers]  measurable  quantities of the
{hormone} [peptide] into the human bloodstream. We believe that this formulation
may  {expedite}  [accelerate]  the  regulatory  approval  process  for  an  oral
Calcitonin  product  because it should be easier to  establish  its  performance
{efficacy}  as  compared  to a  formulation  that  does not  produce  measurable
Calcitonin  blood levels.  We believe that the  components of {the  proprietary}
[our  patented]  oral  {formulation}  [product]  also can enable the delivery of
other peptides and we have initiated  studies to  investigate  this  possibility
internally and in collaboration with others.


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,   {clinical}
[human] testing, and marketing of products derived from our research activities.
However, we may, in some cases, retain the responsibility for {clinical} [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.  {Under  the terms of the
license  agreement,  we are eligible to receive up to $48.5 million in milestone
payments  during  the  course  of the  development  program  if  milestones  are
achieved.} Through December 31, 2000, we {have} recognized an aggregate of $16.5
million in revenue due to the  achievement  of specified  milestones,  including
$2.0 million in 2000. {If a product is successfully commercialized, we will also
receive revenue from the sale of raw material to Pfizer and royalties on product
sales by Pfizer and its  affiliates.}  [Pfizer began a Phase I/II human study in
April 2000 and patient  dosing 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. ]


     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


                                       23


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.  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 {clinical} [human] trials. {may be required}
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.

     o Other  License or  Distribution  Arrangements.  In  addition to the joint
venture with SPG, we have entered into  distribution  agreements for {the} [our]
injectable {formulation of} 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 {forms of }Calcitonin
[products].  However,  {there is no assurance that} [we may not be successful in
our efforts to sign] any  additional  revenue  generating  agreements.  {will be
signed}


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 {finished}
pharmaceutical products. In the development,  manufacture and sale of {amidated}
peptide  {hormones}  products,  we {and our  licensees}  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.  We believe that the unique
safety and {efficacy  characteristics } [effectiveness] of Calcitonin,  combined
with our patented  {hormone}  [peptide]  manufacturing  process and our patented
oral  {delivery  technology}  [formulation],  will  enable  it 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.
{Success} [Our success] will further depend on {the} [our]  {avail}ability  {of}
[to obtain]  adequate  funding and {the  success in} [on]  developing,  testing,
protecting,   producing  and  marketing  products  and  obtaining  their  timely
regulatory approval. {There is no assurance} [We are always at risk] that others
{will not} [may]  develop  superior  processes or products that would render our
processes or products noncompetitive or obsolete.


Product Manufacture

     We have been producing salmon  Calcitonin since 1992. We constructed a cGMP
facility for the  production  of  {pharmaceutical  grade}  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.


                                       24




      The  facility  can be  {reconfigured}  [modified]  to increase  Calcitonin
production  capacity.   However,  if  [we  are  successful  in  our  efforts  to
commercialize] an oral Calcitonin product {is successfully  commercialized},  we
expect that we {will} [may] incur  additional  expenditures to expand or upgrade
our manufacturing operations {to satisfy all of our supply obligations under our
license  agreement  with  Pfizer}.  Although the  facility  initially is devoted
exclusively to Calcitonin  production,  it also is suitable for producing  other
peptide {hormone} 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. {The facility was inspected by} 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 {no
assurance}  [the  risk]  that  our  operations  {will}  [might  not]  remain  in
compliance or that approval by other  agencies will [not] be obtained.  The [FDA
must  approve  the]  facility  {will  require  approval  by the FDA} in order to
manufacture  Calcitonin or other  peptides for  {commercial}  sale in the United
States.


Government Regulation


      Our laboratory research,  development and production  activities and those
of our {licensees and}  collaborators  are subject to significant  regulation by
numerous  federal,  state,  local and  foreign  governmental  authorities.  {The
commercial sale of a pharmaceutical  product in the United States requires} [FDA
approval,  following]  the  successful  completion  of various  animal and human
studies {and approval of the product by the FDA}[, 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 {no assurance} [a risk]
that [any]  additional  regulatory  approvals {will be obtained}  [required] for
{the}  [our]  production  facility  or for any of our  products  {or that  these
approvals will }[will not] be obtained in a timely manner. {The} [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.



     {Our  production  facility  may be  audited  by  the}  [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  {guidelines}.  These  guidelines  require that  production
operations be conducted in strict compliance with our {own written protocols for
reagent qualification, process execution, data recording, instrument calibration
and  quality  monitoring}  [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  {deviations}
[changes] from these {protocols}  [guidelines]  have occurred.  A suspension [by
any of these  agencies]  could have a material  adverse  impact on our  {future}
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   {associated   with
malignancy}.  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, {there is no


                                       25


assurance that} [it is uncertain  whether or when] the Type II Variation will be
approved [by the CPMP].



     {The  approved  European  dossier  can  be  readily  cited  by  regulatory}
[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  {such}  [those]
non-European Union countries, and thereby could speed up product launch. We have
been  notified  by  Switzerland  that  it  intends  to  approve  our  injectable
Calcitonin  product  for the  treatment  of  osteoporosis,  Paget's  disease and
hypercalcemia;  however, the timing of that approval is uncertain.  In addition,
we believe that the {clinical}  [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
             {biologically}  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  {clinical}  [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 {pilot} human studies in the United
Kingdom.  These studies  indicated  that the majority of those who received oral
Calcitonin  showed  levels of the  {hormone}  [peptide] in blood  samples  taken
during the trial that were greater than the minimum levels generally regarded as
being  required for maximum  {therapeutic}  [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
{hormone}  [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 {clinical}  [human]  trials.  The results of this trial  indicated
that every test subject showed levels of the {hormone}  [peptide] in their blood
samples that  exceeded  the minimum  levels  generally  regarded as required for
maximum {therapeutic} [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, {and}
a Phase I/II study  began in April 2000 [and]  patient  dosing  [for this study]
{has been} [was]  completed [in December 2000] {and results are being  analyzed.
However,  there is no assurance that the results of the prior human studies will
be repeated in this clinical  trial.} [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 {fundamental}  [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.

                                       26



     {Under  the  terms  of  the  license  agreement  with  Pfizer,  Pfizer  has
responsibility  for conducting the clinical trials and for obtaining  regulatory
approval  of our  oral  Calcitonin  product  from the FDA and  other  regulatory
agencies.}  There {is no assurance}  [are risks] that [we will not be successful
in licensing this product,  that] a safe and effective  oral  {delivery  system}
[product]  will [not] be developed,  that {Pfizer} [we] will [not] be successful
in obtaining regulatory approval of an oral Calcitonin product,  {or} [and] that
we {and Pfizer} will [not] succeed in developing, producing or marketing an oral
Calcitonin product.


Development of {a}[our] Nasal Calcitonin Product


     A major  pharmaceutical  company  received  FDA  approval  in 1995  for the
marketing of a nasal spray {delivery system for} Calcitonin [product], which has
substantially enlarged the U.S. market for Calcitonin. During 1999, we completed
preliminary  human studies for our proprietary  nasal  Calcitonin  {formulation}
[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  {clinical}  [human] testing [of] our nasal  {formulation}  [product] as a
treatment for osteoporosis.  In February 2000, we began U.S.  {clinical} [human]
studies. {A} [In December 2000, we successfully  completed a] {clinical} [human]
study demonstrating {equivalent  bioavailability} [similar blood levels] between
our  {formulation}  [product] and that of an existing nasal Calcitonin  product.
{was  successfully  completed in December 2000} [We have initiated a] {A} second
{clinical}  [human] study {is under way and} [with final results]  expected {to}
{concluded in early} [in mid-] 2001. We are  {negotiating}  [seeking] to license
our nasal Calcitonin  {formulation}  [product] in the U.S. [and other countries]
for the treatment of osteoporosis. However, {there is no assurance that} [we may
not be  successful  in our  efforts to  conclude] a license  agreement  {will be
completed,  that}[,  to obtain]  governmental  approval of {such product will be
obtained,  or that} [our nasal Calcitonin  product,  or to manufacture and sell]
the product. {will be successfully commercialized}


Collaborative Research Programs

     We are currently engaged in two collaborative research programs:


         o   Rutgers  University  College of  Pharmacy  continues  to study oral
             {drug}  delivery   {technology   for}  [of]  Calcitonin  and  other
             peptides.

         o   {In} [We are in]  collaboration  with Yale University {we are} [to]
             {investigating}   [investigate]   {novel}  [new]  applications  for
             various  {amidated}  peptide[s],  {hormones}  including  Calcitonin
             gene-related  peptide.  In 1996,  we  reported  that  {the}  [this]
             peptide  accelerated  bone  growth  and  prevented  bone loss in an
             animal model  system.  However,  {there is no  assurance  that the}
             [this] peptide {will} [may not] have the same effect in humans[. {,
             or that we would be able to develop, manufacture or market this} 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] {drug}
delivery {technologies}. To date, the following six U.S. patents have issued:

         o   Immunization  By  Immunogenic   Implant,  a  method  for  producing
             antibodies for developing diagnostic medical {tasks} [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



                                       27


         o   two patents covering {our} oral delivery {technology} [of peptides]

     Other  applications  are  pending.  We also have made  filings in  selected
foreign countries,  and numerous foreign patents have issued. However, {there is
no  assurance  that any of} our pending  applications  {will} [may not] issue as
patents {or that}  [and] our issued  patents  {will}  [may not]  provide us with
significant  competitive advantages.  Furthermore,  {there is no assurance that}
[our]  competitors {will not} [may]  independently  develop or obtain similar or
superior technologies.

     Although  we believe our patents  and patent  applications  are valid,  the
{invalidation}  [repeal]  of one  or  more  of  our  key  patents  could  have a
significant  adverse  effect upon our  business.  {There  generally  are greater
difficulties in detecting}  [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.  {has been  patented by others}  Under 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
{commercialize} [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 {no assurance} [a risk] that
these  secrecy  obligations  {will not} [could] be breached  {to our  detriment}
[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 {February 5}[April 2], 2001 we had 67 full-time  employees.  Twenty
[one] were engaged in research, development and regulatory activities, {36} [35]
were  engaged in  production  activities  and 11 were  engaged  in  general  and
administrative functions. Ten 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 83% 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 {$9.4} [$11.5] million on research activities in {1997, $9.0}
[2000,  $9.4] million in [1999,]  {1998,} and {$9.4}  [$9.0]  million in {1999.}
[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.

                                       28




     Our 32,000  square foot cGMP  production  facility,  of which 18,000 square
feet are  currently  being used for the  production  of  {pharmaceutical  grade}
Calcitonin  and can be used for the production of other  peptide[s]  {hormones],
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  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.

      In July 2000,  Reseau de Voyage Sterling,  Inc. filed suit against Unigene
in the Supreme Court of the State 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.  Unigene has moved to
have the case  transferred to federal court. The plaintiff is seeking damages of
$2  million.  [Following  the  deposition  of the  plaintiff,  counsel  for  the
plaintiff withdrew and the court has stayed the case until May 2001, to give the
plaintiff an  opportunity  to seek new  counsel.  ] We believe that this suit is

Committees of the Board of Directors


{Several important functions of the}
     [The] Board of Directors {may be performed by} [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

                                       30


fees paid to the auditors for audit and non-audit services.  The current members
of the Audit Committee are Messrs. Jay Levy, Bloom and Hendrickson.

     Compensation Committee.  The responsibilities of the Compensation Committee
include  reviewing  and  approving  the  compensation,  including  salaries  and
bonuses,  of  our  officers.   The  Compensation  Committee  also  oversees  the
administration  of our 401(k) plan and reviews and approves general benefits and
compensation  strategies.  The current members of the Compensation Committee are
Messrs. Jay Levy, Bloom and Hendrickson.

     Stock Option Committee (2000 Stock Option Plan). The Stock Option Committee
for the 2000 Stock Option Plan,  subject to the limitations of the plan, selects
the employees to be granted options, fixes the number of shares to be covered by
each  option  grant,  and  determines  the  exercise  price and other  terms and
conditions of each option.  The current  members of this Stock Option  Committee
are Messrs. Bloom and Hendrickson.

     Stock Option  Committee  (Directors  Stock Option  Plan).  The Stock Option
Committee for the Directors Stock Option Plan, subject to the limitations of the
plan, interprets the plan and makes all determinations  necessary for the plan's
administration.  The current members of this Stock Option  Committee are Messrs.
Jay Levy, Warren Levy and Ronald Levy.

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. Hendrickson and Dr.
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,

(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.


Compensation Committee Interlocks and Insider Participation


{Executive}
         [The Board of Directors  determined  executive]  compensation for 2000.
{was  determined  by the Board of  Directors}  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.

         {During 1995,  Warren P. Levy,  Ronald S. Levy,  Jay Levy,  and another
family member loaned a total of $1,905,000 to Unigene.  $1,850,000 of this total
was secured by secondary  liens on the  Fairfield  plant and  equipment  and the
Boonton  manufacturing  equipment.  The notes bear interest at the Merrill Lynch
Margin Loan Rate plus .25% (9.875% at December 31, 2000). A total of $440,000 in
principal  repayments  as made during 1996. In 1997, an aggregate of $200,000 in
principal  amount was converted into 57,200 shares of Unigene  common stock.  In
1998, an aggregate of $225,000 in principal  amount of these loans was converted
into 163,635 shares of Unigene common stock. In each case, the conversion  price
was slightly  higher than the then market  price of the Unigene  common stock at
the time of  conversion.  Warren  Levy and Ronald Levy each loaned to Unigene an
additional  $50,000 during 1999. During 2000, Jay Levy, Warren Levy, Ronald Levy
and another  family member loaned Unigene an additional  $1,733,323,  leaving an
outstanding balance of $2,873,323 at December 31, 2000.}

         {During 1999,  Jay Levy loaned Unigene  $1,500,000  evidenced by demand
notes bearing  interest at 6% per year.  During the third  quarter of 1999,  Jay
Levy loaned  Unigene 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.  Unigene 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 terms of the notes  require
Unigene to make  installment  payments  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.  Jay Levy has agreed  temporarily  to postpone
current  payments.  No interest has been paid to date on any of the loans. As of
December 31, 2000, accrued interest totaled approximately $922,000.}

         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  February  2000,  Jay Levy  loaned us
$300,000.  This  loan was  repaid in April  2000.  During  the third and  fourth
quarters of 2000, Jay Levy and another family member loaned Unigene an aggregate
of $1,655,000 in demand loans and Warren Levy and Ronald Levy loaned  Unigene an
aggregate of $78,323 in demand  loans.  As of December 31, 2000,  total  accrued
interest  on  these  loans  was  $922,000  and the  outstanding  loans  by these
individuals to Unigene totaled $4,743,323 and consisted of:

o loans from the Levys 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) that are
classified as short-term debt. These loans are secured by a security interest in
Unigene's equipment and/or real property.

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
6% per year. 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.

         Interest and  principle  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, Jay Levy,  Warren Levy and
Ronald Levy loaned to us an  additional  $1,610,000  at the Merrill Lynch Margin
Loan Rate plus .25%,  of which  $500,000  is secured by a security  interest  in
certain of our patents. No interest has been paid on these loans.

     The following table shows  information as of {December 31, 2000} [March 31,
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.

     The  ownership  percentages  listed on the table are based on  {44,425,929}
[46,436,940]  shares of Unigene  common stock  outstanding  as of {December  31,
2000.} [March 31, 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.

                            The Financing Transaction


General

     On  December  18,  2000,  Unigene  entered  into a  common  stock  purchase
agreement  with Fusion  Capital Fund II,  LLC,[which  we amended as of March 30,
2001.  Under the common stock  purchase  agreement,  as amended,]  {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.  {The common stock is to be  purchased}
[Fusion is committed to purchase the shares] over a twenty[-]four  month period,
subject to a {6} [six-]month extension or earlier termination at our discretion.
The selling price of the shares will be equal to the lesser of (1) $15.00 or (2)
a price based upon the future market price of the common stock without any fixed
discount to the market price.


     In addition to the shares [and the warrant  that] we have {agreed to} issue
[d] to Fusion 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.  {The issuance and
sale to Fusion of any additional  shares may require that Unigene first} [We may
be required to] obtain the approval of {its} [Unigene] stockholders {of} [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].


Purchase of shares under the common stock purchase agreement


     Under the common stock purchase  agreement,  Fusion will purchase shares of
our common stock by  purchasing  from time to time a specified  dollar amount of
our common stock.  Subject to our mandatory purchases and the termination rights
described  below,  during each 30-day period  during the term of the  agreement,
Fusion will purchase $875,000 of our common stock. {This} [We may decrease this]
amount {may be  decreased  by us} at any time that the price of our common stock
is less than $15 per  share.  If our stock  price  equals or  exceeds  $4.00 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.


The selling price per share is equal to the lesser of:

                                       35



     -   the lowest sale price of our common stock on the day of submission of a
         purchase notice by Fusion; or

     -   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

     -   $15.00


     The {selling price will be adjusted for} [common stock  purchase  agreement
provides  for an  adjustment  of  the  selling  price  if]  any  reorganization,
recapitalization,  non-cash dividend,  stock split or other similar  transaction
{occurring}  [occurs]  during the fifteen (15) trading days in which the closing
sale price is used to compute the selling price. {Notwithstanding the foregoing}
[However], Fusion may not purchase shares of common stock under the common stock
purchase  agreement if Fusion or its affiliates would beneficially own more than
9.99% of our then  aggregate  outstanding  common  stock  immediately  after the
proposed purchase. If the 9.99% limitation is ever reached this shall not effect
or limit Fusion's  obligation to fund the required  monthly  purchase  amount of
$875,000  or  Fusion's  mandatory  purchase  obligation  under the common  stock
purchase agreement.


      We have authorized the issuance and sale of up to 6,000,000  shares of our
common stock to Fusion under the common stock purchase agreement. Based upon the
number of shares we have  authorized,  our selling price will need to average at
least  $3.50 per share for us to receive  the  maximum  proceeds  of $21 million
under the common stock purchase  agreement.  Assuming a selling price of {$1.44}
[$0.55] per share (the  closing  sale price of the common  stock on {February 5}
[April 2,]  2001) and the  purchase  by  Fusion  of the full  amount of shares
purchasable under the common stock purchase agreement, proceeds to us would only
be  {$8,640,000}  [$3,300,000]  unless we choose  to issue  more than  6,000,000
shares.

     The following table sets forth the number of shares of Unigene common stock
that  could be sold to  Fusion  under  the terms of the  common  stock  purchase
agreement at varying  purchase  prices,  assuming  Unigene does not exercise its
right under the common stock purchase agreement to suspend purchases by Fusion:

Our right to prevent purchases

     At any time or from time to time,  so long as the closing sale price of our
common stock has been below $15.00 for the most recent three  trading  days,  we
shall have the unconditional right to prevent any purchases effective upon three
trading days prior notice. To the extent we need to use the cash proceeds of the

                                       36


sales of common  stock under the common  stock  purchase  agreement  for working
capital or other business purposes, we do not intend to restrict purchases under
the common stock purchase agreement.

Our mandatory purchase rights

     If the closing  sale price of our common  stock on each of the five trading
days immediately prior to the first trading day of any 30-day period is at least
$4.00,  we have the right to  require  purchase  by Fusion of part or all of the
remaining  balance of the $21 million  (in such  amounts as  determined  by us),
during such time or times as Fusion shall  determine  during the next two 30-day
periods,  provided  the closing  sale price of our common  stock  during the two
30-day periods remains at least $4.00.

Our termination rights

     If at any time the closing  sale price of our common  stock for each of any
ten  consecutive  trading days is below  $15.00,  we may, at any time within the
next three trading days, give notice to Fusion exercising our right to terminate
the common  stock  purchase  agreement.  Such notice  shall be  effective  three
trading  days  after  Fusion  receives  such  notice.  We may not  exercise  our
termination  rights in  anticipation  of,  or in  connection  with,  a change of
control or other major  transaction  unless the change of control or other major
transaction has been publicly disclosed for at least 60 trading days.

Consequences of a major transaction within 60 trading days after a Unigene
termination

     If within 60  trading  days  after  Unigene  terminates  the  common  stock
purchase agreement, Unigene publicly discloses that a major transaction has been
consummated,  or may be consummated,  Fusion will be entitled to a payment in an
amount  equal to the number of shares of Unigene  common  stock that  Fusion was
entitled to purchase  under the common stock  purchase  agreement on the date of
termination  (calculated  as of the  date  of  termination),  multiplied  by the
amount,  if any,  by which (1) the  average of the  closing  sale prices for the
Unigene common stock for the ten trading days immediately  following either: (A)
the public  disclosure of the major  transaction or (B) the  consummation of the
major transaction,  as selected by Fusion,  exceeds (2) the selling price of the
Unigene common stock  (calculated  in accordance  with the common stock purchase
agreement)  as of the date of  termination.  Fusion  may elect to  receive  this
payment either in cash or in shares of Unigene common stock.

Indemnification of Fusion

     Unigene  has  agreed  to  indemnify  and  hold  harmless   Fusion  and  its
affiliates,  shareholders, officers, directors, employees and direct or indirect
investors and their agents or other representatives from and against any and all
liabilities  and related  expenses,  including  reasonable  attorneys'  fees and
disbursements  incurred  by any of them as a result  of, or  arising  out of, or
relating  to, any breach of a Unigene  representation  or  warranty  made in the
transaction  documents  or  related  instruments;  any  breach of any  covenant,
agreement  or  obligation  of Unigene in the  transaction  documents  or related
instruments;  or any cause of action,  suit or claim brought or made against any
of them arising out of or resulting from the execution, delivery, performance or
enforcement of the transaction documents or any related instruments.

     Unigene's  indemnification  obligations  do not extend to any  liability or
expenses that directly and primarily result from the gross negligence or willful
misconduct   of  the  person   indemnified.   To  the  extent   that   Unigene's
indemnification obligations are unenforceable for any reason, Unigene has agreed
to  make  the  maximum  contribution  to the  payment  and  satisfaction  of any
liability and expense that is permissible under applicable law.


                                       37



Effect of performance of the common stock purchase agreement on Unigene and our
stockholders


     All shares  registered in this offering will be freely  tradable,  however,
Fusion has agreed not to sell the shares  issued as a  commitment  fee until the
earlier of termination or maturity of, or default under,  the agreement.  {It is
anticipated}  [Fusion  has  advised  Unigene  that it  anticipates]  that shares
registered  in this  offering will be sold over a period of up to 24 months from
the  date  of this  prospectus.  The  sale of a  significant  amount  of  shares
registered  in this  offering at any given time could cause the trading price of
our common  stock to decline and to be highly  volatile.  Fusion may  ultimately
purchase  all of the shares of common  stock  issuable  under the  common  stock
purchase  agreement,  and it may  sell  all of the  shares  of  common  stock it
acquires upon purchase. Therefore, the purchases under the common stock purchase
agreement may result in  substantial  dilution to the interests of other holders
of our common stock. However, we have the right to block purchases of the common
stock purchase agreement and to require termination of the common stock purchase
agreement  if the  closing  sale price of our common  stock is below  $15.00 per
share for a period of ten consecutive trading days.


No short-selling or hedging by Fusion

     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.

Events of default

     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:


     -   if for any reason the shares offered by this prospectus  cannot be sold
         {pursuant to} [under] this  prospectus  for a period of 10  consecutive
         trading  days or for more than an  aggregate  of 30 trading days in any
         365-day period;


     -   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;

     -   the  failure  of  Unigene  or the  Unigene  common  stock  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;

     -   notice from us or our  transfer  agent that either of us intends not to
         comply  with a proper  request  for  purchase  under the  common  stock
         purchase agreement; our failure to confirm Fusion's purchase notice; or
         the failure of the  transfer  agent to issue shares of our common stock
         upon delivery of a purchase notice;

     -   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;

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

                                       38



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


Commitment shares issued to Fusion

     Under the terms of the  common  stock  purchase  agreement,  [as  amended,]
Fusion {will}[has] receive[d] {1,331,009} [2,000,000] shares of our common stock
as a commitment fee. [In addition,  Fusion also received  five-year warrants for
1,000,000  shares of our common stock,  exercisable at $.50 per share as part of
its  commitment  fee.]  Unless an event of default  occurs,  these  shares  [and
warrent  shares] must be held by Fusion until the earlier of the maturity of the
common  stock  [purchase]  agreement  or the  date  the  common  stock  purchase
agreement has been terminated.

No variable priced financings

     Until the  termination  of the common  stock  purchase  agreement,  we have
agreed not to issue,  or enter into any  agreement  with respect to the issuance
of, any variable priced equity or variable priced equity-like  securities unless
associated  with a  pharmaceutical  licensing  transaction  or we have  obtained
Fusion's prior written consent.

Holdings of Fusion upon termination of the offering

     Because  Fusion may sell all,  some or none of the common stock  offered by
this prospectus,  no estimate can be given as to the amount of common stock that
will be held by Fusion upon early termination of the offering.

                               SELLING STOCKHOLDER

     The selling  stockholder  is Fusion Fund II,  LLC.  Under the common  stock
purchase  agreement,  Fusion  agreed to purchase up to $21 million of our common
stock.  The purchase  price of our common stock is based upon the future  market
price of our common stock.

     We have authorized the issuance and sale of 6,000,000  shares of our common
stock to Fusion under the common  stock  purchase  agreement.  We have the right
under certain  conditions to suspend and/or  terminate the common stock purchase
agreement  without any payment or liability to Fusion.  We have {also agreed to}
issue[d]  {1,331,009}  [2,000,000]  shares  of  common  stock  to  Fusion  as  a
commitment fee under the common stock purchase agreement.  [In addition,  Fusion
also received warrants for 1,000,000 shares of our common stock,  exercisable at
$.50 per  share  as part of its  commitment  fee.]  Unless  an event of  default
occurs,  these  shares [and  warrent  shares]  must be held by Fusion  until the
earlier of the maturity date or the date the common stock purchase agreement has
been terminated. This prospectus relates to the offer and sale from time to time
by Fusion of these shares.  The common stock purchase  agreement is described in
detail under the heading "The Financing Transaction."


     Because the number of shares of Unigene common stock that will be purchased
by Fusion under the common stock purchase  agreement will depend on the purchase
price  of the  purchase  shares,  which  will be  determined  at the time of the
purchase,  and  because  the  number of shares  purchased  may be reduced to the
extent that Unigene elects to suspend Fusion purchases,  the aggregate number of
purchase  shares that will be offered for sale by Fusion is not  determinable at
this time. If the number of purchased shares offered for sale by this prospectus
is insufficient to cover all of the purchased shares and the commitment  shares,
Unigene  has agreed with Fusion to file a  registration  statement  with the SEC
registering  the  additional  shares.  {All of these  shares  are  deemed  to be
beneficially owned by} Steven G. Martin and Joshua B. Scheinfeld, the principals
of Fusion[,  are deemed to be  beneficial  owners of all of the shares  owned by
Fusion].  Messrs. Martin and Scheinfeld have shared voting and dispositive power
of the shares being offered {pursuant to} [under] this prospectus.



                                       39


     Except for the financing transaction, Fusion has had no position, office or
other  material  relationship  with Unigene or affiliates  within the past three
years. Under the terms of the common stock purchase agreement, Fusion has agreed
that it will not purchase  shares of Unigene common stock under the common stock
purchase  agreement if, after giving effect to the  purchase,  Fusion,  together
with  its  affiliates,  would  beneficially  own  in  excess  of  4.99%  of  the
outstanding  shares of Unigene common stock. If the 4.99% limitation is reached,
Unigene,  at its option,  has the right to increase the limitation to 9.99%.  If
the 9.99% limitation is reached, Fusion will remain obligated to comply with its
purchase  obligations under the common stock purchase  agreement,  but otherwise
would be prohibited from increasing its percentage ownership.


                              PLAN OF DISTRIBUTION



     {The}  [Fusion  Capital  Fund II, LLC,  is offering  the shares of Unigene]
common  stock  offered by this  prospectus.  {is being  offered  by the  selling
stockholder,  Fusion  Capital  Fund II,  LLC} The  common  stock  may be sold or
distributed  from  time to time by the  selling  stockholder,  or by  donees  or
transferees  of, or other  successors in interests to, the selling  stockholder,
directly to one or more purchasers or through  brokers,  dealers or underwriters
who may act solely as agents or may acquire such common stock as principals,  at
market  prices  prevailing  at the  time of  sale,  at  prices  related  to such
prevailing market prices, at negotiated prices, or at fixed prices, which may be
changed.  {The}  [Fusion and its  successors  may effect the] sale of the common
stock  offered  by  this  prospectus  {may  be  effected}  in one or more of the
following methods:

     -   ordinary brokers' transactions;

     -   transactions involving cross or block trades;


     -   purchases by brokers,  dealers or  underwriters as principal and resale
         by such  purchasers  for their own accounts  {pursuant to} [under] this
         prospectus;


     -   "at the market" to or through market makers or into an existing  market
         for the common stock;

     -   in other  ways not  involving  market  makers  or  established  trading
         markets, including direct sales to purchasers or sales effected through
         agents;

     -   in privately negotiated transactions; or

     -   any combination of the foregoing.

     In  order  to  comply  with  the  securities  laws of  certain  states,  if
applicable,  the shares may be sold only through  registered or licensed brokers
or dealers.  Under state securities laws, the shares may not be sold unless they
have been  registered or qualified  for sale in such state or an exemption  from
such registration or qualification requirement is available and complied with.

     Brokers, dealers,  underwriters or agents participating in the distribution
of the shares as agents may  receive  compensation  in the form of  commissions,
discounts or concessions from the selling  stockholder  and/or purchasers of the
common stock for whom such  broker-dealers may act as agent, or to whom they may
sell as principal, or both. The compensation paid to a particular  broker-dealer
may be less than or in excess of customary commissions.


                                       40



     The  selling  stockholder  is an  "underwriter"  within the  meaning of the
Securities Act of 1933 with respect to this transaction.  Any broker-dealers who
act in  connection  with the sale of the  shares  hereunder  may be deemed to be
"underwriters"  within the meaning of the  Securities  Act, and any  commissions
they  receive  and  proceeds  of any  sale of the  shares  may be  deemed  to be
underwriting discounts and commissions under the Securities Act.

     Neither we nor the selling stockholder can presently estimate the amount of
compensation that any broker, dealer, underwriter or agent will receive. We know
of  no  existing  arrangements  between  the  selling  stockholder,   any  other
stockholder,  broker,  dealer,  underwriter  or  agent  relating  to the sale or
distribution  of the shares.  At a time a particular  offer of shares is made, a
prospectus supplement,  if required, will be distributed that will set forth the
names of any  agents,  underwriters  or dealers  and any  compensation  from the
selling stockholder and any other required information.

     We will pay all of the expenses incident to the registration,  offering and
sale of the  shares  to the  public  other  than  commissions  or  discounts  of
underwriters, broker-dealers or agents. Unigene has also agreed to indemnify the
selling stockholder and related persons against specified liabilities, including
liabilities under the Securities Act [of 1933].

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors,  officers and controlling  persons of Unigene, we
have been advised that in the opinion of the SEC such indemnification is against
public   policy  as  expressed  in  the   Securities   Act  and  is   therefore,
unenforceable.

Fusion and its  affiliates  have  agreed not to engage in any direct or indirect
short selling or hedging of our common stock during the term of the common stock
purchase agreement.

     The  selling  stockholder  and  any  other  person  participating  in  such
distribution  will be subject to  applicable  provisions of the exchange act and
the rules and regulations thereunder,  including, without limitation, Regulation
M {of the exchange act} [under the Securities  Exchange Act of 1934],  which may
limit the timing of purchases  and sales of any of the shares of common stock by
the selling  stockholder and any other  participating  person.  Regulation M may
also  restrict  the  ability of any person  engaged in the  distribution  of the
common stock to engage in market-making activities with respect to the shares of
common stock. All of the foregoing may affect the marketability of the shares of
common stock and the ability of any person or entity to engage in  market-making
activities with respect to the shares of common stock.

     Unigene has entered into a registration  rights agreement with Fusion under
which it has agreed to maintain the  effectiveness  under the  Securities Act of
1933 of the  registration  statement  to which  this  prospectus  relates.  This
offering  will  terminate on the earlier of (1) the date on which the shares are
eligible for resale without restrictions {pursuant to} [under] Rule 144(k) under
the  Securities  Act or (2)  the  date  on  which  all  shares  offered  by this
prospectus have been sold by the selling stockholder.


                                  Legal Matters

     The validity of the Unigene common stock offered by this prospectus will be
passed upon for Unigene by Covington & Burling, Washington, D.C.

      Unigene's  audited  financial  statements as of December 31, [2000] {1999}

and upon the  authority of KPMG LLP as experts in accounting  and auditing.  The
report of KPMG LLP covering these 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.

                           UNIGENE LABORATORIES, INC.
                          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.

                                      F-8


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 1O1,  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,  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."


                                      F-9


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 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  totaled  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.

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

                                      F-12


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

                                      F-13


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 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

                                      F-14


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.

10.   Obligations Under Capital Leases

The Company entered into various lease  arrangements  during 1999 and 1998 which
qualify as capital leases.

12.   Stockholders' Equity

In 1996,  the  placement  agent,  in  connection  with the  issuance  of the 10%
Debentures,  received a five-year  warrant to purchase  454,000 shares of Common
Stock at an  exercise  price of $2.10  per  share as  partial  compensation  for
services  rendered.  Through December 31, 2000, an aggregate of 322,000 of these
warrants has been exercised and 132,000 remain unexercised.

In October 1996, the Company completed a private placement of 4,218,804 Units at
a price of $1.75 per Unit. Each Unit consisted of (i) one share of Common Stock,
(ii)  one  quarter  of a Class C  Warrant,  (each  whole  Class  C  Warrant  was
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
an exercise price of $3.00 and expired  unexercised on October 11, 1999. The fee
paid to the  placement  agent  in the  transaction  consisted  of an  additional
296,935 Units in lieu of cash compensation. The net proceeds to the Company were
approximately $7 million.

In October 1994, the Company  entered into an agreement with a consultant  whose
compensation for its services included the issuance of warrants,  exercisable at
$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.

In connection with the services rendered by various consultants during 1997, the
Company  issued an aggregate of 75,000 stock  purchase  warrants,  expiring from
1999 to 2002,  exercisable at prices ranging from $2.25 to $3.41 per share,  and
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
an additional  warrant to purchase 373,002 shares of Common Stock at an exercise
price of $1.126 per share, expiring in 2005, for arranging the Fusion financing.
During 2000, the Company issued to various  consultants 850,536 shares of Common
Stock upon the  exercise of warrants at exercise  prices  ranging  from $1.38 to
$2.43 per share. In addition,  the Company issued to various consultants 263,360
shares of Common  Stock upon the  cashless  exercise of an  aggregate of 475,623
warrants at exercise prices ranging from $.46 to $2 per share.

During  1998,  an  aggregate  of $681,000  in  principal  amount of  convertible
debentures,  plus $44,000 of accrued interest,  was converted into approximately
663,000  shares of Common  Stock.  During 1999,  an aggregate of  $2,000,000  in
principal amount of convertible  debentures,  plus $191,000 of accrued interest,
was converted into approximately 3,703,000 shares of Common Stock. See Note 6.

In August 1998,  an aggregate of $225,000 in principal  amount of notes  payable
from  stockholders  was  converted  into  163,635  shares of  Common  Stock at a
conversion  price of $1.375 per share;  such  conversion was at a price slightly
higher than the then market price of the Common Stock.

                                      F-16


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
average exercise price of $2.11.

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%
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.

As of December 31, 2000, options to purchase 310,000 shares and 3,463,850 shares
of Common Stock were available for grant under the 1999 and 2000 Plans.

The Company  accounts for options  granted to employees and directors  under APB
Opinion No. 25. Had  compensation  cost for  options  granted to  employees  and
directors been determined  consistent with SFAS No. 123, the Company's pro forma
net loss and pro forma  net loss per share  would  have  been as  follows  as of
December 31:

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.


                                      F-19


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.
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


                                      F-20


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.

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


                                       II-1


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 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-7


         (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.
