delivery  dates  therefor) for the  succeeding  twelve (12) month period,  which
report W-L shall update monthly; provided, however, that

                                       24

with  respect to each  monthly  update,  W-L may not change the forecast for the
succeeding  three (3) months by more than ten  percent  (10%) of the amount that
W-L forecasted for such three (3) month period in its previous update.

                  3.3      Commercial Supply Forecasts.

                           (a) No later  than two (2) years  prior to the day on
which W-L  projects it will  initially  Launch the  Product,  W-L shall  provide
Unigene with a good faith forecast of W-L's annual requirements for Raw Material
for the next five (5) years,  which forecast W-L shall update  annually no later
than the end of the second Calendar Quarter of each Calendar Year.

                           (b) No  later  than  nine  (9)  months  prior  to the
projected filing date of the NDA in the United States, W-L shall provide Unigene
with a good faith  forecast  estimating  W-L's monthly  requirements  of the Raw
Material (and the desired  delivery dates) for the succeeding  twelve (12) month
period,  which forecast W-L shall update no later than thirty (30) days prior to
each Calendar Quarter;  provided,  however,  that with respect to each quarterly
update,  W-L (a) may not change the forecast for the initial Calendar Quarter in
the updated  twelve (12) month period at all from the amount that W-L forecasted
for such  Calendar  Quarter  in its  previous  update,  (b) may not  change  the
forecast for the second  Calendar  Quarter by more than ten percent (10%) of the
amount that W-L forecasted for such Calendar Quarter in its previous update,

                                       25

and only to the extent  that such change  results in a forecast  amount for such
Calendar  Quarter that is between ninety percent (90%) and  one-hundred  and ten
percent (110%) of the amount that W-L  forecasted  for such Calendar  Quarter in
the  update  that  preceded  its  previous  update,  and (c) may not  change the
forecast  for the third  Calendar  Quarter  in such  period by more than  twenty
percent (20%) of the amount that W-L forecasted for such Calendar Quarter in its
previous  update.  W-L shall  promptly  notify  Unigene  of any  changes  in the
circumstances  on the basis of which the  forecasts  were  determined  and which
materially affect the amount of W-L's anticipated  requirements,  as reported in
the forecasts  given to Unigene  hereunder,  and W-L and Unigene shall work with
each other to reach a mutually acceptable solution;  provided, however, that W-L
shall be  obligated to purchase,  and Unigene  shall be obligated to sell,  such
quantities  of the Raw Material as are set forth in the firm  forecast,  as such
forecast may be amended from time to time pursuant to the preceding sentence.

                  3.4      Purchase Orders.

                           (a)  With  respect  to  development  supplies  of Raw
Material, W-L shall issue to Unigene a firm purchase order for purchases of such
Raw  Material  during  each month not later than  thirty  (30) days prior to the
commencement  of such  month;  provided,  however,  W-L  shall be  obligated  to
purchase at least such quantities of Raw Material as are set forth in the most

                                       26

recent  forecast  pursuant to Section 3.2 for such month;  and provided  further
that  Unigene  shall not be obligated  to supply  quantities  of Raw Material in
excess of such  quantities  of Raw  Material as are set forth in the most recent
forecast pursuant to Section 3.2 for such month.

                           (b)  With  respect  to  commercial  supplies  of  Raw
Material, W-L shall issue to Unigene a firm purchase order covering purchases of
such Raw Material during each Calendar Quarter,  not later than thirty (30) days
prior to the commencement of such Calendar Quarter; provided, however, W-L shall
be  obligated  to purchase at least such  quantities  of Raw Material as are set
forth in the most recent  forecast  pursuant to Section 3.3(b) for such Calendar
Quarter;  and provided  further  that  Unigene  shall not be obligated to supply
quantities  of Raw Material in excess of such  quantities of Raw Material as are
set forth in the most  recent  forecast  pursuant  to  Section  3.3(b)  for such
Calendar Quarter.

                           (c) In the event that the terms of any purchase order
issued pursuant to this Section 3.4 are not consistent with this Agreement,  the
terms of this Agreement shall prevail.

                  3.5 Delivery.  Delivery of each order of Raw Material shall be
made Ex Works (Incoterms 1990) at a facility to be designated by Unigene.  Title
to and  risk  of  loss  of the Raw  Material  shall  pass to W-L at the  time of
delivery to the carrier. Unigene shall promptly invoice W-L for all Product

                                       27

shipped.  Invoices shall be accompanied by the  certificate of analysis for each
invoiced lot of Raw Material.

                  3.6 Inability to Supply. Unigene understands and agrees that a
reliable source of Raw Material is critical to W-L. Should Unigene  believe,  at
any time  during  the term of this  Agreement,  that it may be  unable to supply
W-L's forecasted  requirements of Raw Material, then it shall advise W-L thereof
and of the steps it will take to help insure that it will be able to continue to
supply  W-L's  forecasted  requirements  of  Raw  Material.  In the  event  that
Unigene's  manufacturing facility is destroyed or otherwise  compromised,  or is
not  adequate  to  produce  W-L's  reasonably  forecasted  requirements  of  Raw
Material,  Unigene  shall  use  its  best  efforts  to  rebuild  or  expand  its
manufacturing  facilities,  as the  case  may  be,  or  qualify  a  third  party
manufacturer,  whichever  is likely to enable  Unigene  more quickly to meet its
supply  obligations,  taking into  consideration  the quantities of Raw Material
forecasted by W-L together with any obligations Unigene may have to supply third
parties with Raw Material;  provided,  however,  that Unigene shall consult with
W-L and keep W-L apprised  concerning any steps that Unigene proposes to take in
order to restore or expand its capacity to produce the Raw  Material,  including
without limitation qualifying a third party manufacturer; and provided, further,
that W-L agrees to cooperate with and provide  reasonable  assistance to Unigene
in the event that Unigene seeks to

                                       28

qualify a third  party  manufacturer.  In the event  that  Unigene  is unable to
produce  sufficient  Raw  Material  to meet the orders of all of its  customers,
Unigene  shall  supply  W-L on a  priority  basis  with such  quantities  of Raw
Material  as  Unigene  is  able  to  produce,  up to  the  amounts  required  to
manufacture the quantities of the Product  corresponding to the sales levels set
forth for the relevant year on Annex D hereto (and, for years thereafter,  up to
the amounts required to manufacture  quantities of the Product  corresponding to
the  sales  levels  set  forth for the  final  year  listed on Annex D  hereto);
provided,  however, that in the event that such inability to supply shall result
from a force majeure,  as defined in Section 15.1, then Unigene shall supply W-L
with its pro rata allocation of available Raw Material  calculated  based on the
firm forecasts of W-L and Unigene's other customers.

                  3.7 Warranty.  Unigene  warrants that, at the time of delivery
of the Raw Material to W-L: (i) the Raw  Material  will have been  manufactured,
stored and shipped in accordance with applicable  Good  Manufacturing  Practices
and all other applicable laws, rules, regulations or requirements of the FDA and
other Regulatory Authorities which have granted Approvals, (ii) the Raw Material
will have been  manufactured in accordance with the  specifications  provided to
W-L by  Unigene  for the Raw  Material,  and  conform  with the  certificate  of
analysis provided pursuant to Section 3.5, (iii) the Raw

                                       29

Material will not be adulterated or misbranded under the Federal Food, Drug, and
Cosmetic Act, as amended,  and similar provisions of the laws of other countries
as to which  Approvals  have been  granted;  (iv) title to all Raw Material sold
hereunder  will pass to W-L as provided  herein  free and clear of any  security
interest,  lien, or other  encumbrance;  and (v) the Raw Material will have been
manufactured,  stored and tested in facilities which are approved by the FDA and
any other  applicable  Regulatory  Authorities at the time of such  manufacture,
storage and testing,  to the extent such approval is required by applicable law;
provided, however, that to the extent that Unigene reasonably determines,  after
consultation  with W-L,  that  requirements  imposed by a  Regulatory  Authority
(other than the FDA) in a country for approval of such facilities are materially
inconsistent  with those required by the FDA or are otherwise  onerous,  Unigene
shall have the right to terminate  this  Agreement with respect to such country,
by  Notice  to W-L,  whereupon  such  country  shall  no  longer  be part of the
Territory,  provided that Unigene shall not terminate this Agreement pursuant to
this Section 3.7 with respect to the United States, Canada, Europe or Japan.

                  3.8 Price.  The parties agree that the purchase  price for Raw
Material  during  the  term  of the  parties'  respective  purchase  and  supply
obligations under Section 3.1 shall be [ ] per kilogram; provided, however, that
in the event that W-L shall lower the

                                       30

selling  price of the  Product  (from the selling  price of the Product  then in
force or, if such change is made prior to Launch, the selling price indicated in
then-current W-L marketing  projections) in a country in which Approval has been
granted,  in order  to meet  competition  from one or more  nasally-administered
calcitonin  products  sold in such  country by a third party under  license from
Unigene and/or using Raw Material purchased from Unigene, then the total payment
by W-L to Unigene in respect of the  Product  sold by W-L,  its  Affiliates  and
Sublicensees  in such  country,  on a per unit  basis  (equal  to the sum of the
transfer price of Raw Material used in the manufacturing thereof and the royalty
payments  pursuant to Section  6.1(b) with  respect to Net Sales  thereof)  (the
"Cost of Goods"), shall not exceed [ ], [
       ], or [ ], as determined pursuant to Section 6.1(b)(i)(A)(a)-(c),  of the
Net Sales in such country; provided,  further, that in no event shall Unigene be
obligated  to supply  W-L with  commercial  supplies  of the Raw  Material  at a
purchase  price lower than [ ] per  kilogram;  and provided,  further,  that the
parties  agree to  determine  and settle any  amounts  owing by one party to the
other pursuant to the first proviso to this Section 3.8,  within sixty (60) days
after the end of each  Calendar  Quarter;  and provided,  further,  that Unigene
agrees to supply W-L until the third  anniversary  of the initial  Launch of the
Product with (a) up to a maximum of 250 grams of Raw Material at [ ] and

                                       31

reasonable  quantities  of  Raw  Material  in  excess  of 250  grams  at [ ] per
kilogram, all for use only in connection with W-L's Development Activities,  and
(b) up to a maximum of 50 grams of Raw Material at [ ] and reasonable quantities
of Raw Material in excess of 50 grams at [ ] per  kilogram,  all for use only in
the manufacture of Product  promotional  samples.  Terms of payment shall be net
thirty (30) days from the date of invoice.

                  Unigene   agrees  that,   during  the  term  of  the  parties'
respective  purchase and supply  obligations  under Section 3.1, in the event it
supplies  Raw  Material  to any  third  party  (including,  without  limitation,
Unigene's  licensee  for  the  oral  calcitonin  product  in the  Semi-Exclusive
Territory)  for  use in an  oral  calcitonin  product  to be sold or used in the
Semi-Exclusive  Territory  for a total  payment  (including  the transfer  price
thereof and any applicable royalty payment obligation) that is lower than [ ] of
net  sales  (calculated  on a basis  similar  to the  calculation  of Net  Sales
hereunder) of such product in the  Semi-Exclusive  Territory by such third party
or its  Affiliates,  then the sum of the  transfer  price and royalty  hereunder
shall be reduced to that paid by such third party.  Unigene  shall notify W-L in
writing  promptly  after  entering into an agreement to supply Raw Material to a
third party under circumstances that would trigger a reduction in the sum of the
transfer price and

                                       32

royalty hereunder to W-L under the preceding sentence.  Further,  W-L shall have
the right, upon reasonable notice to Unigene, to cause an independent  certified
public accountant  reasonably acceptable to Unigene to review the relevant books
and records of Unigene to verify the  accuracy of the  reduction  granted to W-L
pursuant to the first sentence of this paragraph.

                  In the event  that W-L shall  face  price  competition  in the
Marketing and sale of the Product in one or more countries in the Territory from
nasally-administered  calcitonin  product(s) sold by a third party that is not a
licensee of Unigene and not using Raw Material purchased from Unigene,  then the
parties  agree to meet in  order to  discuss  appropriate  responses,  including
without limitation ways in which to make the Product more competitive.

                  3.9 Specifications  Amendments.  Unigene reserves the right to
amend  and/or  supplement  the  Product  Specifications  as they  relate  to Raw
Material  unilaterally  on six (6) months' prior written notice (or such shorter
period  as may be  required  by law) for the  purpose  of  complying  with  Good
Manufacturing Practices or the rules, regulations, guidelines or requirements of
the Regulatory  Authorities.  Unigene may not otherwise amend and/or  supplement
the Product  Specifications  without the prior  written  approval of W-L,  which
approval  shall not be  unreasonably  withheld.  Unigene  shall provide W-L with
prior written notice of any amendments

                                       33

or supplements  that Unigene is  considering  and cooperate with W-L in order to
ensure that, to the extent required,  such changes are submitted to and approved
by the relevant Regulatory Authorities.

                  3.10  Records.   Unigene  shall  maintain,   or  cause  to  be
maintained,  all records necessary to comply with all applicable laws, rules and
regulations  in the  United  States  relating  to  the  manufacture  of the  Raw
Material.  All such  records  shall be  maintained  for  such  period  as may be
required  by law,  rule or  regulation;  provided,  however,  that  all  records
relating to the manufacture,  stability and quality control of each batch of the
Raw  Material  supplied  to W-L  hereunder  shall be retained at least until the
first  anniversary  of the end of the  approved  shelf life for the Raw Material
from such batch.

                  3.11 Third Party Raw Material  Supply.  Unigene  shall use its
best  efforts  consistent  with  applicable  law to ensure that any Raw Material
which  Unigene may supply to a party other than W-L or any of its  Affiliates or
Sublicensees  shall not be used to manufacture,  Finish, use or sell the Product
or  any  other  oral  calcitonin  product  in  the  Territory  (other  than  the
Semi-Exclusive Territory) in violation of the rights licensed and/or acquired by
W-L under this Agreement.

                  3.12 Quality Assurance.  The parties agree to develop mutually
acceptable procedures for annual quality

                                       34

assurance audits of Unigene's Raw Material manufacturing facilities by W-L.

                                    SECTION 4
                        MARKETING AND SALE OF THE PRODUCT

                  4.1      W-L Obligation.

                           (a)      W-L shall use its best efforts to make the
Product  a  commercial  success  in each  country  in the  Territory;  provided,
however,  that W-L shall be deemed to have satisfied its best efforts obligation
under this Section 4.1 to the extent that W-L actively and aggressively Markets,
distributes  and sells the Product as it would (and makes a commitment  thereto,
financial and otherwise, commensurate with) those of its own brands and products
with similar commercial potential that it actively and aggressively promotes. In
any event,  W-L shall  commence  Marketing of the Product in each country in the
Territory as promptly and as  expeditiously  as possible after Approval has been
granted in such country,  and shall promptly give Unigene  written notice of the
date of Launch in each such country;  provided,  however, that,  notwithstanding
anything to the contrary  contained  herein or in the Marketing Plans, W-L shall
Launch the Product (i) in each of the Priority  Markets within six (6) months of
the day on which the  relevant  Approval  and any  regulatory  pricing  approval
required for governmental  reimbursement in such country has been granted,  (ii)
in each Secondary Market in which clinical trials in addition to those performed
in one or more of the Priority

                                       35

Markets are required for Approval, within six (6) months of the day on which the
relevant Approval and any regulatory  pricing approval required for governmental
reimbursement  in such  country has been  granted,  and (iii) in each  Secondary
Market in which no such  additional  clinical  trials are required for Approval,
within  six (6)  months of the later of (a) the day the first  Approval  that is
referenceable in such Secondary Market,  and (b) the day any regulatory  pricing
approval  required for  governmental  reimbursement  in such  country,  has been
granted;  provided,  however, if W-L fails to Launch the Product in any Priority
Market or Secondary Market within twelve (12) months of the date of grant of the
relevant  Approval for such  country,  Unigene shall have the right to terminate
this Agreement with respect to such country pursuant to Section 14.2.

                           (b)  W-L  shall,  at its  sole  expense,  obtain  all
Approvals  necessary to accomplish the Marketing,  distribution  and sale of the
Product in each country in the Territory,  and any pricing  approvals,  or their
equivalent, required in connection therewith in such country. W-L shall bear all
costs and expenses arising out of or relating to the Marketing, distribution and
sale of the Product. All sales of Product in the Territory shall be made by, and
for the account of, W-L or its Affiliates or Sublicensees, as the case may be.

                                       36

                  4.2      Finishing Product.

                           (a) W-L shall (i)  Finish the  Product in  accordance
with the  Product  Specifications,  and (ii)  obtain  all  regulatory  approvals
necessary  to  Finish  the  Product,  import  the Raw  Material  to the place of
Finishing,  and ship the Product to the place of sale.  W-L shall bear all costs
and expenses arising out of or relating to such activities.

                           (b) W-L  warrants  that it shall (i) comply  with all
applicable laws, rules and regulations of each country in the Territory relating
to the importation of Raw Material or the Product,  as the case may be, and (ii)
Market,  distribute,  and sell  Product that (A) has been  Finished,  stored and
shipped by or on behalf of W-L or its Affiliates in accordance  with  applicable
Good Manufacturing Practices and all other rules, regulations or requirements of
the  applicable  Regulatory  Authorities,  (B) has  been  manufactured  from Raw

applicable  Good  Manufacturing  Practices and all other rules,  regulations  or
requirements of the applicable Regulatory Authorities,  (C) has been Finished in
accordance with the Product Specifications,  and (D) has not been adulterated or
misbranded by W-L, its Affiliates or  Sublicensees  under the Federal Food Drug,
and  Cosmetic  Act,  as  amended,  or the  other  applicable  laws,  rules,  and
regulations of the countries in the Territory.

                                       37

                           (c) W-L shall  maintain,  or cause to be  maintained,
all records  necessary to comply with all applicable laws, rules and regulations
in the  Territory  relating to the  Finishing of the  Product.  All such records
shall  be  maintained  for  such  period  as may be  required  by  law,  rule or
regulation;  provided,  however,  that all records  relating  to the  Finishing,
stability and quality  control of each batch of the Product shall be retained at
least until the first  anniversary of the end of the approved shelf life for the
Product made from such batch.

                  4.3 Compliance.  W-L and Unigene shall comply, and shall cause
their  Affiliates  (and, in the case of W-L,  Sublicensees,  and, in the case of
Unigene,  its licensees in the  Semi-Exclusive  Territory)  to comply,  with all
applicable  laws,  regulations  and  Approvals in  conducting  their  respective
activities relating to the manufacturing, Finishing, Marketing, distribution and
sale of the  Product  in  each  country  in the  Territory,  including,  without
limitation, all requirements as to pre-marketing approval of product labelling.

                  4.4 Marketing Plans, Marketing Reports and Launch Meetings.
                      
                           (a) From time to time prior to the initial  Launch of
the Product and thereafter during the term of this Agreement, W-L shall promptly
furnish Unigene with copies of W-L's Marketing Mix Document,  Global  Pre-Launch
Plan and

                                       38

Global Marketing Plan or any comparable reports for the Product,  as well as any
updates to the foregoing.

                           (b)  Unigene  and W-L agree to meet on a  semi-annual
basis through their designated  representatives,  beginning six (6) months prior
to the  initial  Launch,  at which  meetings  W-L shall make a  progress  report
describing the Marketing  activities it has performed to date and evaluating the
work performed in relation to the goals of the Marketing  Plan, and provide such
other information as Unigene or its representatives may reasonably request.

                           (c)  Unigene  shall  have  the  right to  attend  the
meetings for the Launch of the Product.

                  4.5  Marketing  Materials.  W-L  shall  develop,  at its  sole
expense,  appropriate  advertising and promotional  materials for the Product in
the Territory,  and shall own all rights,  title and interest in such materials.
W-L shall furnish Unigene with all significant English language  advertising and
promotional   materials  used  in  connection   with  the  Marketing,   sale  or
distribution of the Product on a quarterly  basis or as reasonably  requested by
Unigene.

                  4.6 Development  and Use of Trademarks.  W-L shall develop all
Product  Trademarks.  Unigene shall not, and shall not permit its  Affiliates or
licensees to, use in their  respective  businesses any trade name,  trademark or
other designation which is similar to or substantially similar to

                                       39

any of the Product Trademarks, or which so nearly resembles any of them as to be
likely to cause deception or confusion.

                  4.7      Liability Insurance.

                           (a) During the term of this  Agreement  and for three
(3) years thereafter,  W-L shall maintain,  at its sole expense,  clinical trial
and product  liability  insurance  relating to the Product that is comparable in
type and amount to the  insurance it maintains  with respect to its most similar
other prescription  pharmaceutical  products that are Marketed,  distributed and
sold in the  Territory,  and which  names  Unigene as an insured  party,  as its
interests may appear.

                           (b) From and  after  the date of first  supply of Raw
Material to W-L for the Phase I Clinical Trials,  through the third  anniversary
of the termination or expiration of this Agreement,  Unigene shall maintain,  at
its sole expense, product liability insurance relating to the Raw Material in an
amount of at least Two Million  United  States  Dollars (US  $2,000,000)  annual
limit, which names W-L as an insured party, as its interest may appear.

                  4.8  Competition.  W-L  agrees  that,  during the term of this
Agreement and for one (1) year after the termination  hereof,  it shall not, and
shall not permit any of its Affiliates or Sublicensees  to,  develop,  Market or
sell in any  country in the  Territory  any  product  (other  than the  Product)
containing the Compound or any derivative thereof; provided,  however, that such
obligation shall not survive with respect

                                       40

to the  Territory  or a  country,  as the case may be,  in the  event  that this
Agreement  shall be terminated by W-L with respect to the Territory  pursuant to
Sections  14.3 or 14.5,  or by Unigene  with  respect to a country  pursuant  to
Section 3.7, 11.6(a) or 11.6(b).  The parties  acknowledge that all restrictions
contained  in this  Section  4.8 are  reasonable,  valid and  necessary  for the

                           Europe,  the tenth  anniversary  of the Launch of the
                           Product  in such  country,  and (2) the date on which

                                    be [                   ];

                                       45


                           b)       on any increment of aggregate Net Sales of

                                    any Valid Claim in a country, the

                                    provided  that no royalty  obligation  shall
                                    continue under this Section 6.1(b) after the
                                    tenth anniversary of the date on which there

                           Provided,  however,  that,  even  after  the  Royalty
                           Transition Date occurs in a country, the Net Sales in
                           such country  shall be included in the  aggregate Net
                           Sales for  purposes of  determining  the  appropriate
                           royalty rate for those countries in which the Royalty
                           Transition Date has not yet occurred (for purposes of
                           illustration  only,  an example of an annual  royalty
                           calculation  after the  Royalty  Transition  Date has
                           occurred  in part  but not  all of the  Territory  is
                           attached as Annex E hereto); and provided further the
                           Net Sales in the  Semi-Exclusive  Territory  shall be
                           included in the  aggregate  Net Sales for purposes of
                           determining  the  appropriate  royalty  rates for all
                           countries in the Territory; and provided further that
                           if  applicable  law  so  permits,  then  the  Royalty
                           Transition  Date for each of the  countries in Europe
                           shall  be  determined  in the  manner  set  forth  in
                           Section 6.1(b)(i)(y)(A)(1)(I); and

                                       46

                  (B)      after the Royalty Transition Date in a country,
                           the royalty rate in such country shall be zero.
                             
                                                     AND
                           (ii)  any amounts paid to Unigene pursuant to
                  Section 3.8 for Raw Material contained in such
                  Product.

                  W-L shall pay any  amounts  owed to Unigene  pursuant  to this
Section  6.1(b)(i)(y)  on a quarterly basis within sixty (60) days following the
end of each full or partial  Calendar Quarter during the term of this Agreement.
If, for the twelve (12) month  period  commencing  on the first day of the first
full Calendar Quarter after the Launch in each of the United States,  Europe and
Japan,  or the  twelve  (12)  month  periods  beginning  on the first and second
anniversary  thereof,  the amounts paid under Section 6.1(b)(i)(y) do not exceed
the amounts stated in Section  6.1(b)(i)(x)  for such country or Europe for such
period,  W-L shall pay the difference  within forty-five (45) days of the end of
the  relevant  twelve (12) month  period.  Net Sales made in foreign  currencies
shall be converted  into United States Dollars using the average of the exchange
rates set forth in the United States eastern  edition of The Wall Street Journal
for the last business day of the full or partial  Calendar Quarter in which such
Net  Sales  were  booked  and the last  business  day of the  previous  Calendar
Quarter.

                                       47

                  With respect to any partial Calendar Quarter or Calendar Year,
any  Minimum  Royalty  Amount  and Net Sales  thresholds  for the  royalty  rate
adjustments  for such period shall be prorated to reflect the percentage of such
period that elapsed before this Agreement  terminated.  (By way of example,  and
not in limitation  of the parties'  rights  hereunder,  if this  Agreement  were
terminated  at the end of the sixth month in any twelve month  period,  both the
Minimum  Royalty  Amount,  if any,  and the Net  Sales  thresholds  (but not the
corresponding  royalty  rates) for such period would be reduced by fifty percent
(50%).)

                  Each payment hereunder shall be accompanied by written report,
certified  by an officer  of W-L or his or her  designee,  providing  a detailed
breakdown of the Net Sales, and the components thereof, during such period.

                  6.2 Withholding  Taxes.  W-L shall pay any and all withholding
taxes or similar  charges imposed by any  governmental  unit in the Territory on
any amounts  due to Unigene  from W-L  pursuant to this  Section 6 to the proper
taxing authority, and proof of payment of such taxes or charges shall be secured
and sent to  Unigene  as  evidence  of such  payment.  All  amounts  paid by W-L
pursuant  to this  Section  6.2 shall be paid for the  account  of  Unigene  and
deducted from the amounts due from W-L to Unigene pursuant to Section 6.1.

                                       48

                  6.3 Equity  Investment.  As partial mutual  consideration  for
entering into this  Agreement,  the parties agree to enter into a Stock Purchase
Agreement  of even date  herewith,  in the form of Annex C hereto,  pursuant  to
which W-L shall purchase an equity interest in Unigene.

activities  as Unigene and W-L may mutually  agree,  (ii) approve any changes in
the  Development  Plan,  (iii)  formulate  recommendations  or proposals for W-L
management related to (A) all formulations of the

                                       49

Product used in the Phase I Clinical Trials and their foreign  equivalents,  and
the final  formulations of the Product used in the Phase III Clinical Trials and
their foreign  equivalents,  (B) the protocol and design of all clinical trials,
and (C) the labelling and packaging of any finished  formulation of the Product,
and (iv) take such other  actions as are set forth  herein or as the parties may

                           (a)  The  Development   Team  shall  take  action  by
consensus of the members present; provided,  however, that final decision-making
authority  with respect to decisions and actions of the  Development  Team shall
reside with W-L.

                           (b) The Development  Team shall meet at least monthly
or as otherwise  agreed by the  Development  Team  Leaders,  at times and places
mutually  agreed  upon,  to discuss  the  overall  progress  of the  Development
Activities,  the status of the Development  Plans,  any problems  arising in the
course of the Development Activities,  and any other matter that a member of the
Development  Team may reasonably  request.  Notwithstanding  the foregoing,  the
parties  shall  regularly  exchange  minutes of the monthly  meetings and Status
Reports every four months regarding the Development Team Activities.

                           (c)  Members  of  the  Development  Team  may  attend
meetings in person, by telephone or by video conference. Upon

                                       50

reasonable notice,  W-L shall furnish video conferencing  facilities for Unigene
at its Morris Plains facility.

                                    SECTION 8
                                    REPORTING

                  8.1  Reporting  by  Parties.   Notwithstanding,   and  without
limitation of, the reporting requirements contained elsewhere in this Agreement,
the parties hereto shall use their commercially  reasonable efforts to keep each
other  informed  of their  respective  Project  Activities,  including,  without
limitation,   material   developments  relating  to  the  performance  of  their
respective obligations under this Agreement.

                  8.2  Financial  Records.   W-L  shall,  and  shall  cause  its
Affiliates  and  Sublicensees  to, keep complete and accurate  books and records
pertaining to the  Marketing,  sale and use of the Product,  including,  without
limitation,  books and records of the Net Sales of Product, in sufficient detail
to calculate  the  royalties  payable  under this  Agreement and to identify the
purchase  order  details for each  customer to which it sells the Product.  Such
books and records shall be retained by W-L and its Affiliates  and  Sublicensees
at least  until  five (5) years  after the end of the period to which such books
and records pertain,  or for such longer period as may be required by applicable
law.

                                       51

                  8.3 Audit of Records.  At the  request of Unigene,  W-L shall,
and shall  cause its  Affiliates  and  Sublicensees  to,  permit an  independent
certified  public  accountant,  to which  W-L has no  reasonable  objection,  at
reasonable  times and upon reasonable  notice,  to examine the books and records
maintained  pursuant  to  Section  8.2 to verify  the  accuracy  of the  royalty
payments  made or payable  hereunder,  but only as to any period ending not more
than two (2) years prior to the date of such request.  Said accountant shall not
disclose to Unigene or any other party any information  except that which should
properly be contained in a royalty  report  required under this  Agreement.  W-L
shall pay any additional  royalties owed to Unigene not later than ten (10) days
after such  accountant  makes its  findings.  Unigene shall pay the cost for any
review of records  conducted at the request of Unigene  pursuant to this Section
8.3,  unless such audit  shall  reveal an  underpayment  by W-L in excess of ten
percent (10%), in which case W-L shall pay the cost of such review.

                                    SECTION 9
                  ADVERSE EVENT AND OTHER INFORMATION EXCHANGE

                  9.1  Notification.  Each party shall provide  prompt Notice to
the other  party of  information  in or coming  into its  possession  or control
concerning  any  unusual  or  unexpected  reaction  or  side  effect,   customer
complaint,  reported defect, adverse reaction, injury or toxicity or sensitivity
reaction associated with commercial and clinical uses, studies,

                                       52

investigations  or  tests of the  Product  (animal  or  human),  whether  or not
determined  to be  attributable  to the  Product,  and  whether  arising  out of
clinical studies or Marketing and sale of the Product. Further, each party shall
notify  the  other's  responsible  drug  safety  department  (or in the  case of
Unigene, its chief executive officer), by facsimile, with a confirmation copy by
mail, such notice to include a copy of the complaint,  as soon as possible,  but
in no event later than four (4) calendar  days (and in those  countries in which
the Regulatory  Authorities require shorter notice, each party shall provide the
other with Notice within  twenty-four (24) hours),  after the time a party first
becomes aware of any information  concerning any serious and/or  unexpected side
effect,  injury,  toxicity or sensitivity reaction or any unexpected  incidence,
and the severity thereof, associated with the Product. "Serious" as used in this
Section 9.1 shall refer to an experience  which (i) is fatal or immediately life
threatening; (ii) requires or prolongs inpatient hospitalization;  (iii) results
in persistent or significant disability and/or incapacity;  (iv) is a congenital
anomaly and/or birth defect, cancer or overdose (intentional or accidental);  or
(v)  is  considered  a  medically   significant   event   (includes   laboratory
abnormalities).  Medically  significant  events  are  those  which  may  not  be
immediately  life  threatening  or  result in death or  hospitalization  but may
jeopardize the patient or may require intervention to prevent

                                       53

one of the outcomes listed above to define Serious.  By way of illustration  and
not  limitation,   examples  of  medically  significant  events  are:  intensive
treatment  in an  emergency  room or at home for  allergic  bronchospasm,  blood
dyscrasia,  convulsions  that do not result in  hospitalization,  development of
drug  dependency  or  drug  abuse  or  laboratory   abnormalities.   Information
concerning  other complaints and other adverse  reactions  regarding the Product
shall be exchanged between the parties in writing promptly, but in any event not
less  frequently than monthly.  W-L shall be responsible  for reporting  adverse
experiences  with  respect  to the  Product  to  the  FDA  in  conformance  with
applicable law;  provided,  however,  that each party shall make such reports as
are necessary to comply with laws and regulations  applicable to it, at its sole
expense.  Each party  shall  promptly  provide  the other  with any  information
concerning  any  adverse  experiences  as  described  above with  respect to the
Product or the  Compound  from  outside  the  Territory,  which is known to such
party, within four (4) calendar days after receipt of notice thereof. Each party
shall have the right to audit the other  party's drug safety  surveillance  data
base to assure regulatory compliance.

                  9.2 Regulatory Action. Each party shall immediately notify the
other of any information  received regarding any threatened or pending action by
the FDA or other  governmental  agency  which may  affect  the  Compound  or the
Product or the continued manufacture, distribution, Marketing,

                                       54

sale or use of the Product.  Upon receipt of any such  information,  the parties
shall  consult in an effort to arrive at a  mutually  acceptable  procedure  for
taking appropriate  action;  provided,  however,  that nothing set forth in this
Section 9.2 shall be construed as restricting  the right of either party to make
a timely  report of such matter to any  government  agency or take other  action
that it deems appropriate or required by applicable law or regulation.

                  9.3 Material Communications.  In addition to the notifications
required by Section 2.6, each party shall  promptly  provide Notice to the other
party of any material communications with any governmental agency concerning the
Product, including, without limitation, adverse drug reaction reports. Copies of
all such material  communications  shall be attached to the Notice sent pursuant
to this Section 9.3.

                                   SECTION 10
                                 PRODUCT RECALL

                  10.1     Notification and Recall.

                           (a) In the  event  that any  governmental  agency  or
authority issues or requests a recall or takes similar action in connection with
the  Product,  or in the event  either party  determines  an event,  incident or
circumstance  has  occurred  which may result in the need for a recall or market
withdrawal,  the party  notified  of or calling  such  recall or similar  action
shall,  within  three  hours,  advise the other party  thereof by  telephone  or
facsimile.

                                       55

                           (b)  Following   notification   pursuant  to  Section
10.1(a),  within  forty-eight  (48) hours,  the  parties'  representatives  from
business,  medical,  regulatory,  quality assurance and legal functions (and any
others deemed  necessary by a party) shall  discuss  whether or not to conduct a
recall  (except  in the case of a  government-mandated  recall),  and if so, the
timing of the  recall,  the  breadth,  extent and level of customer to which the
recall shall reach,  the  strategies  and  notifications  to be used,  and other
related issues. In the event that such representatives  cannot agree on any such
decision, the issue shall be resolved by senior management of W-L.

                           (c) In  the  event  that  Unigene  recommends  that a
recall be conducted in connection  with a problem or potential  problem with the
Raw  Material  that  Unigene  has  identified,  and W-L decides not to conduct a
recall of the Product, then W-L shall indemnify Unigene pursuant to Section 13.4
from and  against  all  Losses  that  Unigene  may incur as a result of any such
failure by W-L to conduct a recall.

                           (d) Nothing set forth in this  Section  10.1 shall be
construed as  restricting  the right of either party to make a timely  report of
such  matter  to any  government  agency  or take  other  action  that it  deems
appropriate or required by applicable law or regulation.

                  10.2  Recall  Expenses.  W-L shall  bear the  expenses  of any
recall of Product; provided, however, that Unigene

                                       56

shall bear the expense of a recall to the extent that such recall  resulted from
Unigene's  breach of its  obligations  hereunder.  Such expenses of recall shall
include,  without  limitation,  the expenses of notification  and destruction or
return of the  recalled  Product and the refund to consumers of amounts paid for
the recalled Product.

                                   SECTION 11
                          INTELLECTUAL PROPERTY RIGHTS

                  11.1 Ownership and Prosecution of Intellectual Property.

                           (a) Except as otherwise expressly provided in Section
5.1,  as  between  the  parties,  Unigene  shall own all right and title to, and
interest  in,  the  Unigene   Patent  Rights,   Licensed   Technology  and  Sole
Improvements of Unigene. Unigene, at its expense and through patent attorneys or
agents of its choice, shall file and prosecute  applications for Patents related
to the foregoing in the United States, Europe and Japan and such other countries
as determined by Unigene or as mutually agreed by Unigene and W-L. Unigene shall
not  abandon  any such  application  for a Patent or permit any  Patent  issuing
therefrom to lapse without first  notifying W-L and  permitting  W-L to continue
the  prosecution  of such  applications  or pay any required fees in the name of
Unigene,  at W-L's expense and through patent attorneys or agents of its choice.
W-L shall not become an  assignee of any  application  for Patent or Patent as a
result of its continuing the

                                       57

prosecution  of an  application  for patent or paying any fees according to this
Section.

                           (b) W-L  shall  own any and all  interest  in the W-L
Patent  Rights and Sole  Improvements  of W-L.  W-L,  at its expense and through
patent attorneys or agents of its choice, shall file and prosecute  applications
for Patents related to the foregoing in the United States,  Europe and Japan and
such other  countries as determined by W-L or as mutually  agreed by Unigene and
W-L.  W-L shall not  abandon  any such  application  for a Patent or permit  any
Patent issuing therefrom to lapse without first notifying Unigene and permitting
Unigene to continue the  prosecution  of such  applications  or pay any required
fees in the name of W-L, at Unigene's  expense and through  patent  attorneys or
agents of its choice.  Unigene  shall not become an assignee of any  application
for  Patent  or  Patent  as a result of its  continuing  the  prosecution  of an
application for patent or paying any fees according to this Section.

                           (c) Neither party shall license, assign, sell, convey
or  otherwise  transfer  its rights in any Joint  Improvement  without the prior
consent of the other party,  which consent shall not be  unreasonably  withheld.
The parties shall consult with one another to coordinate  their  activities with
respect to obtaining appropriate Patent protection for Joint Improvements.

                                       58

                           (d) The non-filing party or the party not responsible
for prosecuting an application for patent  according to 11.1 (a) or (b) (Unigene
or W-L, as the case may be) shall assist,  as reasonably  requested by the other
party,  and cooperate in the  activities  set forth in this Section  11.1.  Each
party shall keep the other party currently  informed of all steps to be taken in
the  preparation and  prosecution of all  applications  filed by it according to
this Section 11 and shall furnish the other with copies of such applications for
Patents,  amendments thereto and other related correspondence to and from patent
offices and permit the other party to offer its comments  thereon before a party
makes a submission to a patent office which could materially affect the scope or
validity  of the patent  coverage  that may  result.  Each party shall offer its
comments promptly. All determinations regarding whether or not an Improvement is
a Sole Improvement or a Joint  Improvement  shall be made in accordance with the
patent laws of the United States.

                  11.2  Ownership  of and  Validity of  Trademarks.  The parties
agree  that W-L shall own all right  and title to and  interest  in the  Product
Trademarks and that Unigene shall own all right and title to and interest in the
Unigene Trademarks

                  11.3  Ownership of  Regulatory  Documentation  and  Approvals.
Unigene shall own all right and title to and interest in all Unigene  Regulatory
Documentation and all information contained therein. W-L shall own all right and

                                       59

title to and interest in all W-L Regulatory  Documentation  and all  information
contained  therein.  For purposes of this Section 11.3, Unigene and W-L shall be
deemed  to  include  their  respective  Affiliates  and,  in the  case  of  W-L,
Sublicensees.

                  11.4 Ownership of Project Information and Inventions.

                           (a) Except as otherwise  provided in this Section 11,
all  right and title to and  interest  in  Project  Information  and  Inventions
developed  or  created  jointly  by the  parties  shall be owned  jointly by the
parties,  and all right and title to and  interest  in Project  Information  and
Inventions developed or created solely by one party shall be owned solely by the
discovering or creating party. All  determinations  regarding whether a specific
Project  Information  and  Invention  was  developed  or created  jointly by the
parties  or  solely  by one  party  shall be made on the  basis of the  relevant
doctrines of the patent laws of the United States.

                           (b) W-L and Unigene each shall  promptly (i) disclose
to the other in  writing,  and shall  cause its  respective  Affiliates  and, if
applicable,  Sublicensees to so disclose, the development, making, conception or
reduction to practice of all Project Information and Inventions, whether created
or discovered solely by a party (and/or its Affiliates  and/or  Sublicensees) or
jointly, as the same are discovered,  invented, made, acquired,  conceived of or
reduced to practice,

                                       60

and (ii), with respect to such solely-owned  Project Information and Inventions,
grant to the other party, without any additional consideration, a non-exclusive,
royalty-free  license (with right to sublicense)  (A) if the licensee is W-L, to
use such  Project  Information  and  Inventions  solely in  connection  with the
Product  in the  Territory,  and (B) if the  licensee  is  Unigene,  to use such
Project   Information   and   Inventions   (1)  in  the  Territory  and  in  the
Semi-Exclusive  Territory,  solely  with  respect  to  products  other  than the
Product, and (2) outside the Territory, with respect to any and all products.

                  11.5      Enforcement of Intellectual Property Rights.

                           (a) In the event of any infringement by a third party
of any intellectual  property rights relating to the Product or the Compound, or
any data related  thereto or developed as a result of or in connection  with the
Project  Activities in the Territory,  including without limitation the Licensed
Technology,  the Unigene Regulatory  Documentation,  any Project Information and
Inventions  owned or controlled  solely by Unigene or licensed to Unigene (other
than Project  Information and Inventions licensed to Unigene pursuant to Section
11.4(b)),  Unigene shall have the first right (but not the obligation) to pursue
any  and  all   injunctive,   compensatory   and  other   remedies   and  relief
(collectively,  "Remedies") against such third party. If Unigene shall determine
not to pursue Remedies with respect to any such infringement within

                                       61

sixty (60) days after  Notice  from W-L  requesting  Unigene to do so,  then W-L
shall have the right (but not the  obligation) to pursue  Remedies  against such
third party.

                           (b) In the event of any infringement by a third party
of any intellectual property rights relating to W-L Regulatory Documentation and
Project  Information and Inventions owned or controlled solely by W-L or jointly
by Unigene and W-L, W-L shall have the first right (but not the  obligation)  to
pursue any and all Remedies  against such third party.  Should W-L determine not
to pursue Remedies with respect to any such infringement  within sixty (60) days
after Notice from Unigene  requesting  W-L to do so, then Unigene shall have the
right (but not the obligation) to pursue Remedies against such third party.

                           (c) In the event that a party shall  pursue  Remedies
hereunder,  the other  party  shall use all  reasonable  efforts  to assist  and
cooperate with the party  pursuing such Remedies.  Each party shall bear its own
costs and  expenses  relating  to such  pursuit.  Any  damages or other  amounts
collected  shall be distributed,  first,  to the party that pursued  Remedies to
cover its costs and expenses and, second,  to the other party to cover its costs
and expenses,  if any,  relating to the pursuit of such Remedies;  any remaining
amount shall be distributed to the party that pursued the Remedies.

                                       62

                  11.6      Infringement of Third Party Rights.

                           (a) If one or more patents  covering the Marketing or
sale of the  Product,  but not the Raw  Material  itself,  has issued to a third
party in the Territory and if W-L reasonably  determines that it is advisable to
obtain a license  from such third party  under such patent or patents,  then W-L
shall  devote all  reasonable  efforts to  obtaining  a license  from such third
party. W-L shall be solely responsible for all royalties and other payments to a
third party under any license  resulting  from the  provisions  of this  Section
11.6(a). If W-L determines that such a license is unnecessary,  W-L may agree to
indemnify  Unigene  for  any and all  liability  that  Unigene  might  incur  in
connection  with the  manufacture  or sale of the Raw Material by Unigene or the
marketing or sale of the Product by W-L in the absence of such a license. In the
event that W-L determines  that such a license is unnecessary and does not agree
to indemnify Unigene in accordance with the preceding sentence, then Unigene may
terminate  this  Agreement  with respect to the country or  countries  involved,
pursuant  to  Section  14.4(a).  In the event  that W-L  determines  that such a
license is  necessary  and (i) the  patent  owner is  unwilling  to grant such a
license,  or  (ii)  the  cost  of  such  a  license  would  render  the  Product
commercially infeasible, then either W-L or Unigene may terminate this Agreement
with respect to the country or countries involved, pursuant to Section 14.4(a).

                                       63

                           (b) If one or more patents  covering the Raw Material
has  issued  to a  third  party  in  the  Territory  and if  Unigene  reasonably
determines  that it is advisable to obtain a license from such third party under
such patent or patents,  then Unigene shall make the necessary  arrangements  to
obtain such  license  under such third party  patent  rights so that Unigene may
continue to meet its supply obligations hereunder. Any costs for such license or
sublicense  shall be the sole  responsibility  of  Unigene.  In the  event  that
Unigene,  despite its  reasonable  efforts,  is unable to obtain such a license,
then W-L may use its  commercially  reasonable  efforts to obtain such a license
from such third party and, if it shall  obtain such a license,  it shall grant a
sublicense  thereunder  to Unigene,  and  Unigene and W-L shall be  responsible,
respectively,  for seventy-five  percent (75%) and twenty-five  percent (25%) of
the  payments to such third party  thereunder.  If W-L is not able to, or elects
not to negotiate such a license,  then Unigene may terminate this Agreement with
respect to the country or countries involved, pursuant to Section 14.4(a).

                           (c) In the event  that a third  party  institutes  or
threatens a patent,  trade secret or other  infringement suit against W-L or its
Affiliates  or  Sublicensees  during the term of this  Agreement,  alleging that
their  Marketing,  sale or use of the Product in the Territory  infringes one or
more patent or other intellectual property rights held by such third

                                       64

party, then W-L shall have the first right (but not the obligation), at its sole
expense,  to assume  direction  and  control of the  defense  of claims  arising
therefrom  (including  the right to settle such claims at its sole  discretion);
provided, however, that W-L shall obtain the written consent of Unigene prior to
ceasing to defend,  settling or otherwise  disposing  of such claims;  provided,
further,  that if Unigene  shall  refuse to provide such  consent,  then Unigene
shall  indemnify  W-L  pursuant to Section 13.3 for any and all Losses that W-L,
its Affiliates or  Sublicensees  may suffer as a result of such refusal.  If W-L
determines  not to assume such  direction  and control,  Unigene  shall have the
right,  at its sole  expense,  to defend,  settle or  otherwise  dispose of such
claims on such terms as Unigene, in its sole discretion, shall deem appropriate.
In the event that W-L controls the defense of an action challenging claims under
the  Unigene  Patents,  all of the  reasonable  expenses  and costs,  including,
without  limitation,  attorneys'  fees and  damage  awards,  incurred  by W-L in
connection  therewith  that  are not  offset  by  proceeds  therefrom  shall  be
creditable  against the royalties due under Section 6.1(b);  provided,  however,
that no royalty payment when due,  regardless of the amount or number of credits
available to W-L in  accordance  with this  Agreement,  shall be reduced by more
than fifty percent (50%).

                           (d) In the  event  that a third  party  institutes  a
patent, trade secret or other infringement suit against

                                       65

Unigene,  W-L or their respective  Affiliates or sublicensees during the term of
this  Agreement,  each  party  shall,  at its  own  cost  and  expense,  use all
reasonable  efforts to assist and  cooperate  with the other party in connection
with the defense of such suit.

                           (e) If (i) as a result of any claim made  against W-L
or any of its  Affiliates  or  Sublicensees  during  the term of this  Agreement
alleging that the  Marketing or sale of the Product by such entity  infringes or
misappropriates  any patent or any other  proprietary  right of a third party, a
judgment is entered by a court of competent jurisdiction from which no appeal is
taken  within the time  permitted  for  appeal,  such that W-L  cannot  sell the
Product in a Priority Market without  infringing the patent or other proprietary
rights of such third party, and (ii) Unigene and/or W-L are unable to obtain the
license referred to in this Section 11.6 within sixty (60) days after such entry

agency pursuant to any statute or regulation of any state or country, a petition
in bankruptcy or insolvency or for  reorganization  or for an arrangement or for
the  appointment of a receiver or trustee of that party or of its assets,  or if
the other party proposes a written  agreement of composition or extension of its

against it, filed in any insolvency  proceeding,  and such petition shall not be
dismissed within sixty (60) days after the filing thereof, or if the other party

in the possession or under the control of W-L or its Affiliates or  Sublicensees
relating  to  the  Compound  or  Product,  including,  without  limitation,  any

files and  materials for the purpose of performing  any  obligations  under this
Agreement that may survive such termination.

respective  successors  and  permitted  assigns.  Except as  expressly  provided
herein, neither party may, without the prior written consent of the other party,

otherwise delegate any of its obligations,  hereunder;  provided,  however, that

                                       89

                  15.6  Governing  Law.  This  Agreement  shall be governed  by,
construed,  and enforced in  accordance  with the laws of the State of New York,
without regard to the choice of law provisions thereof.

                  15.7  Arbitration.

                           (a) Disputes  between the parties arising under or in
connection with this Agreement that are not resolved  pursuant to Section 8.3(b)
or otherwise shall be referred to compulsory  arbitration in accordance with the
Commercial Arbitration Rules of the American Arbitration  Association to be held
in New York,  New York.  The  parties  shall  appoint  an  arbitrator  by mutual
agreement.  If the parties  cannot  agree on the  appointment  of an  arbitrator
within  thirty (30) days after receipt of a demand for  arbitration,  each party
shall  appoint one  arbitrator,  and the two  arbitrators  shall appoint a third
arbitrator.  If the  party-appointed  arbitrators  cannot  agree  on  the  third

                  15.8 Waiver. A party's failure to enforce,  at any time or for
any period of time, any provision of this Agreement, or to exercise any right or
remedy, does not

                                       90

constitute a waiver of such  provision,  right or remedy,  or prevent such party
thereafter  from enforcing any or all provisions and exercising any or all other
rights and remedies.  The exercise of any right or remedy does not constitute an
election or prevent the  exercise of any or all rights or  remedies,  all rights
and remedies being cumulative.

                  15.9  Severability.  If any provision  hereof,  other than the
requirements to pay license fees and royalties  pursuant to Section 6, should be
held  invalid,  illegal or  unenforceable  in any respect,  then, to the fullest
extent permitted by applicable law, (a) all other provisions hereof shall remain
in full force and effect and shall be liberally  construed in order to carry out
the intent of the  parties  as nearly as may be  possible,  and (b) the  parties
agree to use their best efforts to negotiate a provision,  in replacement of the
provision  held  invalid,  illegal or  unenforceable,  that is  consistent  with
applicable law and accomplishes,  as nearly as possible,  the original intention
of the  parties  with  respect  thereto.  To the  fullest  extent  permitted  by
applicable  law, each party hereby waives any provision of law that would render
any provision hereof prohibited or unenforceable in any respect.

                  15.10  Counterparts.  This  Agreement  may be  executed in any
number of counterparts, each of which shall be deemed to be an original, and all
of which, taken together, shall constitute one and the same instrument.

                                       91

                  15.11   Construction.   Except  where  the  context  otherwise
requires,  wherever used the singular  shall include the plural,  the plural the
singular, the use of any gender shall be applicable to all genders. The captions
of this  Agreement are for  convenience  of reference only and in no way define,
describe, extend or limit the scope or intent of this Agreement or the intent of
any provision contained in this Agreement.  The language of this Agreement shall
be deemed to be the  language  mutually  chosen  by the  parties  and no rule of
strict construction shall be applied against either party hereto.

                  15.12 Independent Contractors. The status of the parties under
this Agreement shall be that of independent contractors. No party shall have the
right to enter into any  agreements  on behalf of the other party,  nor shall it
represent to any Person that it has any such right or authority. Nothing in this
Agreement  shall be construed as  establishing  a  partnership  or joint venture
relationship between the parties hereto.

                  15.13  Nasal  Product.  The  parties  agree to use good  faith
efforts to  negotiate  an  agreement  pursuant  to which W-L would  develop  and
commercialize  a nasally  administered  form of the  Compound  (i) in the United
States,  such negotiation to occur within a period of ninety (90) days after the
date of this  Agreement  (or such longer  period as the parties may agree),  and
(ii) in Europe, such negotiation to occur within a

                                       92

period of sixty  (60)  days  after the date of this  Agreement  (or such  longer
period as the parties may agree).

                  15.14 Publicity.  Either party may make any public  disclosure
about this Agreement required by law; provided,  however,  that it shall give at
least three (3) business  days' prior  written  notice to the other party to the
extent  consistent  with  applicable  law.  Neither  party shall issue any press
release or other public disclosure about this Agreement or its terms without the
prior written consent of the other party, except pursuant to this Section 15.14.

                  15.15 Entire Agreement. This Agreement constitutes,  on and as
of the date  hereof,  the entire  agreement  of the parties  with respect to the
subject  matter  hereof,  and all  prior or  contemporaneous  understandings  or
agreements,  whether  written or oral,  between the parties with respect to such
subject matter are hereby superseded in their  entireties.  This Agreement shall
not be amended  in any  respect  whatsoever  except by a further  agreement,  in
writing, fully executed by each of the parties.

                                       93

                  IN WITNESS  WHEREOF,  the parties  have  caused  this  License
Agreement to be duly executed and delivered as of the date first above written.

                            STOCK PURCHASE AGREEMENT

                  This Stock Purchase Agreement (the  "Agreement"),  dated as of
July 15, 1997,  is entered  into by and between  Unigene  Laboratories,  Inc., a
Delaware corporation ("Unigene"), and Warner-Lambert Company, a Delaware
corporation ("Purchaser").

                              W I T N E S S E T H: 

                  WHEREAS,  Unigene and  Purchaser  simultaneously  herewith are
entering  into a License  Agreement,  dated as of July 15,  1997  (the  "License
Agreement"),  pursuant to which Unigene has licensed to Purchaser  rights to use
certain of Unigene's proprietary technology; and

                  WHEREAS,  Unigene in connection  therewith wishes to issue and
sell to Purchaser,  and Purchaser wishes to purchase from Unigene,  on the terms
and  conditions set forth in this  Agreement,  the number of shares of Unigene's
common  stock,  par value $.01 per share (the  "Common  Stock"),  determined  in
accordance with the provisions of Section 1.1 hereof.

                  NOW THEREFORE,  in consideration of the foregoing premises and
the mutual covenants contained in this Agreement and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto, intending to be legally bound, hereby agree as follows:


                                    ARTICLE I
                           PURCHASE AND SALE OF STOCK

         1.1 Purchase of Stock.  On the terms and  conditions  set forth in this
Agreement,  Unigene agrees to issue and sell to Purchaser,  and Purchaser agrees
to purchase  from  Unigene,  at a purchase  price of  $3,000,000,  the number of
shares of Common  Stock  that is equal to the total  obtained  by  dividing  (i)
$3,000,000,  by (ii) the average of the closing  sale prices of the Common Stock
as  reported  by the  Nasdaq  Stock  Market for each  trading  day during the 30
calendar days  preceding  and the 30 calendar days  beginning on the date of the
first  public  announcement  of  the  entry  by the  parties  into  the  License
Agreement;  provided that if the calculation described in this Section 1.1 would
create a fractional  share,  such fractional  share shall be disregarded and the
number of  shares of Common  Stock  purchased  and sold  hereunder  shall be the
number of whole shares.

                                       98


         1.2  Deliveries.  On the  date  of the  execution  of  this  Agreement,
Purchaser  shall deliver to Unigene,  by wire transfer of immediately  available
funds to such bank account as shall be designated by Unigene, an amount equal to
$3,000,000.  Promptly  following the conclusion of the 60-day period referred to
in  Section  1.1,  Unigene  shall  deliver  to  Purchaser  a  stock  certificate
registered in the name of Purchaser  representing the number of shares of Common
Stock determined in accordance with Section 1.1 hereof.


                                   ARTICLE II
                         REPRESENTATIONS AND WARRANTIES

         2.1 Representations  and Warranties of Unigene.  Unigene represents and
warrants to Purchaser that, as of the date hereof:

                  (a) Organization, Good Standing and Qualification.  Unigene is
duly  incorporated,  validly existing and in good standing under the laws of the
State of Delaware.

                  (b)  Authorization.  Unigene has the corporate power necessary
to execute, deliver and perform this Agreement, and such execution, delivery and
performance  have been duly authorized by all necessary  corporate action on the
part of Unigene.  This Agreement has been duly executed and delivered by Unigene
and constitutes a legal,  valid and binding  obligation of Unigene,  enforceable
against Unigene in accordance with its terms.

                  (c) No Violations. The execution,  delivery and performance of
this  Agreement by Unigene  does not and will not: (i) violate any  provision of
Unigene's  Certificate  of  Incorporation  or By-laws;  (ii) violate,  breach or
constitute a default (or an event or condition that with the giving of notice or
the  passage of time or both could  give rise to a default)  under any  material
contract or agreement to which  Unigene is a party or by which Unigene is bound;
(iii) result in the creation of a lien, security interest, charge or encumbrance
on any  property or assets of Unigene;  (iv)  except for such  filings  with the
Securities and Exchange Commission or any state securities  commission as may be
required to perfect a private  placement or limited  offering  exemption for the
sale of the  shares of Common  Stock,  require  the  authorization,  consent  or
approval of, or filing with,  any court or any  administrative  or  governmental
body  pursuant  to any law,  statute,  rule or  regulation  to which  Unigene is
subject  or any order,  judgement  or decree by which  Unigene is bound;  or (v)
constitute a default  under or violate any law,  statute,  rule or regulation to
which Unigene is subject or any

                                       99


order, judgement or decree of any court,  administrative agency or arbitrator by
which Unigene is bound.

                  (d) Litigation.  There is no suit,  action or other proceeding
of any nature pending or, to the best knowledge of Unigene,  threatened  against
Unigene before any court or other  governmental  agency or  instrumentally  that
challenges or seeks to prevent the consummation of the transactions contemplated
by this Agreement.

                  (e) Valid Issuance of Common Stock. The shares of Common Stock
to be issued  pursuant to this  Agreement  have been duly  authorized  and, upon
issuance in accordance with the terms of this Agreement, will be validly issued,
fully paid and nonassessable.

                  (f)  Capitalization.  (a)  The  authorized  capital  stock  of
Unigene  consists of 60,000,000  shares of Common Stock, of which, as of May 15,
1997,  (i) 37,264,165  shares were  outstanding  and (ii) 7,434,719  shares were
reserved for issuance  either upon the  conversion  of  outstanding  convertible
securities or upon the exercise of  outstanding  options and warrants.  There is
only one class of Common Stock.

                  (g)   Securities   Laws.   Assuming   the   accuracy   of  the
representations  and warranties of Purchaser  contained in this  Agreement,  the
sale of the shares of Common  Stock to be issued  pursuant  to the terms of this
Agreement will be exempt from registration  under the Securities Act of 1933, as
amended (the "Securities Act").

         2.2 Representations and Warranties of Purchaser.  Purchaser  represents
and warrants to Unigene that, as of the date hereof:

                  (a) Organization,  Good Standing and Qualification.  Purchaser
is duly  incorporated,  validly  existing and in good standing under the laws of
the State of Delaware.

                  (b) Authorization. Purchaser has the corporate power necessary
to execute, deliver and perform this Agreement, and such execution, delivery and
performance  have been duly authorized by all necessary  corporate action on the
part of  Purchaser.  This  Agreement  has been duly  executed  and  delivered by
Purchaser and  constitutes a legal,  valid and binding  obligation of Purchaser,
enforceable against Purchaser in accordance with its terms.

                  (c) No Violations. The execution,  delivery and performance of
this  Agreement by Purchaser does not and will not: (i) violate any provision of
Purchaser's  Certificate of  Incorporation or By-laws;  (ii) violate,  breach or
constitute a

                                       100


default (or an event or condition  that with the giving of notice or the passage
of time or both could give rise to a default)  under any  material  contract  or
agreement to which  Purchaser is a party or by which  Purchaser is bound;  (iii)
result in the creation of a lien,  security  interest,  change or encumbrance on
any property or assets of Purchaser, (iv) require the authorization,  consent or
approval of, or filing with,  any court or any  administrative  or  governmental
body pursuant to any law,  statute,  rule or  regulation  to which  Purchaser is
subject or any order,  judgement or decree by which  Purchaser is bound; or (iv)
constitute a default  under or violate any law,  statute,  rule or regulation to
which  Purchaser  is  subject or any  order,  judgement  or decree of any court,
administrative agency or arbitrator by which Purchaser is bound.

                  (d) Litigation.  There is no suit,  action or other proceeding
of any nature pending or, to the best knowledge of Purchaser, threatened against
Purchaser before any court or other governmental  agency or instrumentally  that
challenges or seeks to prevent the consummation of the transactions contemplated
by this Agreement.

                  (e) Purchase Entirely For Own Account;  Investment Experience;
Access to  Information.  Purchaser is purchasing  the shares of Common Stock for
its own account without a view to any  distribution  thereof in violation of the
Securities  Act, or any  applicable  state  securities  laws,  and  Purchaser is
experienced  in  evaluation  and making  investments  of this type,  and has had
access  to,  and  has  received,  all  information  concerning  Unigene  that it
reasonably  has  required to  evaluate  its  investment  in the shares of Common
Stock.

                  (f) Accredited Investor. Purchaser is financially able to bear
the risks of an investment  in the shares of Common Stock and is an  "accredited
investor"  within the meaning of Rule 501 of  Regulation D under the  Securities
Act.  Purchaser  understands and  acknowledges  that an investment in the Common
Stock is speculative and involves a high degree of risk.

                  (g) Restricted Securities. Purchaser acknowledges that Unigene
is selling the shares of Common Stock pursuant to an exemption from registration
under Section 4(2) of the Securities Act in reliance on the  representations and
warranties of Purchaser  herein,  and agrees that the shares of Common Stock may
be offered,  sold,  pledged or otherwise  transferred  by Purchaser  only if the
transaction is registered under the Securities Act or is effected pursuant to an
exemption from such registration requirements.

                                      101


                  (h) Legends.  Purchaser agrees that the following legend shall
be placed on the  certificate(s)  evidencing  the shares of Common  Stock for so
long as the shares remain "restricted securities" within the meaning of Rule 144
under the Securities Act:

                  "The  shares  represented  by this  certificate  have not been
                  registered under the Securities Act of 1933, as amended.  Such
                  shares  have  been  acquired  for  investment  and  may not be
                  offered,  sold,  pledged or otherwise  transferred,  except in
                  compliance with the  registration  requirements of said Act or
                  pursuant to an exemption therefrom."

Purchaser  understands  that,  while such legend  remains on the  certificate(s)
evidencing the shares of Common Stock, Unigene will direct its transfer agent to
maintain "stop transfer"  procedures with respect to the shares.  Unigene agrees
that,  when the Shares of Common Stock become  eligible for sale pursuant to the
provisions  of Rule 144(k)  under the  Securities  Act,  Unigene will direct the
transfer  agent to remove  the  above-referenced  legend  from any  certificates
tendered by Purchaser for such purpose.
