         a. Mandatory  Registration.  The Company shall use best efforts to keep
the Registration  Statement effective pursuant to Rule 415 promulgated under the

Statement or file a new registration statement (a "New Registration Statement"),
so as to cover all of such Registrable Securities as soon as practicable, but in
any event not later  than ten (10)  Trading  Days after the  necessity  therefor
arises. The Company shall use it best efforts to cause such amendment and/or New
Registration  Statement to become effective as soon as practicable following the
filing thereof. The Investor and its counsel shall have a reasonable opportunity
to review and comment upon any such amendment and/or New Registration  Statement

         3.       RELATED OBLIGATIONS.

         With respect to the Registration Statement and whenever any Registrable
Securities  are to be  registered  pursuant  to Section 2  including  on any New
Registration  Statement,  the Company shall use its  reasonable  best efforts to

(including  post-effective  amendments)  and  supplements  to  any  registration
statement  and  the  prospectus  used  in  connection  with  such   registration
statement,  which  prospectus  is to be filed  pursuant to Rule 424  promulgated
under the 1933 Act, as may be  necessary to keep the  Registration  Statement or
any New  Registration  Statement  effective at all times during the Registration
Period, and, during such period, comply with the provisions of the 1933 Act with
respect to the disposition of all Registrable  Securities of the Company covered
by the Registration  Statement or any New Registration Statement until such time
as all of such Registrable  Securities shall have been disposed of in accordance
with the intended methods of disposition by the seller or sellers thereof as set
forth in such registration statement.

         b. The Company shall permit the Investor to review and comment upon the
Registration  Statement or any New Registration Statement and all amendments and
supplements thereto at least two (2) Trading Days prior to their filing with the
SEC, and not file any document in a form to which Investor  reasonably  objects.
The  Investor  shall  use its  reasonable  best  efforts  to  comment  upon  the
Registration  Statement or any New Registration  Statement and any amendments or
supplements  thereto  within  two (2)  Trading  Days from the date the  Investor
receives the final version  thereof.  The Company shall furnish to the Investor,
without  charge any  correspondence  from the SEC or the staff of the SEC to the
Company or its representatives relating to the Registration Statement or any New
Registration Statement.


<PAGE>


         c. The Company shall furnish to the  Investor,  (i) promptly  after the
same is prepared and filed with the SEC, at least one copy of such  registration
statement and any  amendment(s)  thereto,  including  financial  statements  and
schedules,  all  documents  incorporated  therein by reference and all exhibits,
(ii) upon the  effectiveness of any registration  statement,  ten (10) copies of
the prospectus  included in such  registration  statement and all amendments and
supplements  thereto  (or such  other  number  of  copies  as the  Investor  may
reasonably  request)  and (iii) such other  documents,  including  copies of any
preliminary or final  prospectus,  as the Investor may  reasonably  request from
time  to  time  in  order  to  facilitate  the  disposition  of the  Registrable
Securities owned by the Investor.

         d. The Company  shall use  reasonable  best efforts to (i) register and
qualify the  Registrable  Securities  covered by a registration  statement under
such other  securities  or "blue sky" laws of such  jurisdictions  in the United
States as the  Investor  reasonably  requests,  (ii)  prepare  and file in those
jurisdictions,   such  amendments  (including  post-effective   amendments)  and
supplements  to such  registrations  and  qualifications  as may be necessary to
maintain the effectiveness  thereof during the Registration  Period,  (iii) take
such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications in effect at all times during the Registration  Period,  and (iv)
take all  other  actions  reasonably  necessary  or  advisable  to  qualify  the
Registrable Securities for sale in such jurisdictions;  provided,  however, that
the  Company  shall not be required in  connection  therewith  or as a condition
thereto to (x)  qualify to do business  in any  jurisdiction  where it would not
otherwise be required to qualify but for this Section 3(d),  (y) subject  itself
to general taxation in any such  jurisdiction,  or (z) file a general consent to
service of process in any such  jurisdiction.  The Company shall promptly notify
the Investor who holds  Registrable  Securities of the receipt by the Company of
any  notification  with  respect  to  the  suspension  of  the  registration  or
qualification of any of the Registrable Securities for sale under the securities
or "blue sky" laws of any  jurisdiction  in the United  States or its receipt of
actual  notice of the  initiation  or  threatening  of any  proceeding  for such
purpose.

         e. As promptly as  practicable  after  becoming  aware of such event or
facts,  the Company shall notify the Investor in writing of the happening of any
event or existence of such facts as a result of which the prospectus included in
any registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements  therein,  in light of the circumstances  under
which they were made,  not  misleading,  and promptly  prepare a  supplement  or
amendment to such  registration  statement  to correct such untrue  statement or
omission,  and deliver ten (10) copies of such  supplement  or  amendment to the
Investor  (or such  other  number  of  copies  as the  Investor  may  reasonably
request).  The Company  shall also  promptly  notify the Investor in writing (i)
when a prospectus or any prospectus  supplement or post-effective  amendment has
been filed, and when a registration  statement or any  post-effective  amendment
has become effective  (notification of such effectiveness  shall be delivered to
the Investor by facsimile on the same day of such effectiveness and by overnight
mail),  (ii) of any  request by the SEC for  amendments  or  supplements  to any
registration  statement or related prospectus or related information,  and (iii)
of the Company's reasonable  determination that a post-effective  amendment to a
registration statement would be appropriate.

         f. The Company  shall use its  reasonable  best  efforts to prevent the
issuance  of  any  stop  order  or  other  suspension  of  effectiveness  of any
registration   statement,   or  the  suspension  of  the  qualification  of  any
Registrable  Securities  for sale in any  jurisdiction  and, if such an order or
suspension  is issued,  to obtain the  withdrawal of such order or suspension at
the earliest  possible moment and to notify the Investor of the issuance of such
order  and the  resolution  thereof  or its  receipt  of  actual  notice  of the
initiation or threat of any proceeding for such purpose.


<PAGE>


         g. The Company  shall (i) cause all the  Registrable  Securities  to be
listed on each securities  exchange or trading system on which securities of the
same class or series  issued by the  Company  are then  listed,  if any,  if the
listing of such Registrable Securities is then permitted under the rules of such
exchange,  or (ii)  secure  designation  and  quotation  of all the  Registrable
Securities on the Principal Market.  The Company shall pay all fees and expenses
in connection with satisfying its obligation under this Section.

         h. The Company  shall  cooperate  with the Investor to  facilitate  the
timely  preparation  and delivery of  certificates  (not bearing any restrictive
legend)  representing  the Registrable  Securities to be offered pursuant to any
registration  statement and enable such certificates to be in such denominations
or amounts as the Investor may  reasonably  request and registered in such names
as the Investor may request.

         i.  The  Company  shall at all  times  provide  a  transfer  agent  and
registrar with respect to its Common Stock.

         j. If  reasonably  requested  by the  Investor,  the Company  shall (i)
immediately  incorporate in a prospectus supplement or post-effective  amendment
such information as the Investor believes should be included therein relating to
the  sale  and  distribution  of  Registrable  Securities,   including,  without
limitation,  information  with respect to the number of  Registrable  Securities
being sold,  the purchase  price being paid  therefor and any other terms of the
offering of the Registrable  Securities;  (ii) make all required filings of such
prospectus  supplement  or  post-effective  amendment as soon as notified of the
matters to be  incorporated  in such  prospectus  supplement  or  post-effective
amendment;   and  (iii)  supplement  or  make  amendments  to  any  registration
statement.

         k. The  Company  shall use its  reasonable  best  efforts  to cause the
Registrable  Securities  covered by any registration  statement to be registered
with or approved by such other  governmental  agencies or  authorities as may be
necessary to consummate the disposition of such Registrable Securities.

         l. Within one (1) Trading Day after any  registration  statement  which
includes the Registrable Securities is ordered effective by the SEC, the Company
shall deliver,  and shall cause legal counsel for the Company to deliver, to the
transfer  agent for such  Registrable  Securities  (with copies to the Investor)
confirmation that such registration statement has been declared effective by the
SEC in the form attached hereto as Exhibit A.

         m. The  Company  shall  take all other  reasonable  actions  reasonably
requested by the Investor to expedite and facilitate disposition by the Investor
of Registrable Securities pursuant to any registration statement.

         4.       OBLIGATIONS OF THE INVESTOR.

         a. The Company shall notify the Investor in writing of the  information
the  Company  reasonably  requires  from the  Investor  in  connection  with any
registration statement hereunder. The Investor shall furnish to the Company such
information  regarding  itself,  the  Registrable  Securities held by it and the
intended method of disposition of the Registrable Securities held by it as shall
be reasonably required to effect the registration of such Registrable Securities
and shall execute such  documents in connection  with such  registration  as the
Company may reasonably request.


<PAGE>


         b. The  Investor  agrees to  cooperate  with the Company as  reasonably
requested by the Company in connection  with the  preparation  and filing of any
registration statement hereunder.

         c. The  Investor  agrees  that,  upon  receipt of any  notice  from the
Company  of the  happening  of any  event  or  existence  of  facts  of the kind
described  in Section  3(f) or the first  sentence of 3(e),  the  Investor  will
immediately  discontinue  disposition of Registrable  Securities pursuant to any
registration   statement(s)  covering  such  Registrable  Securities  until  the
Investor's  receipt of the  copies of the  supplemented  or  amended  prospectus
contemplated  by Section  3(f) or the first  sentence  of 3(e).  Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to promptly
deliver shares of Common Stock without any restrictive legend in accordance with
the terms of the Purchase  Agreement in connection  with any sale of Registrable
Securities  with  respect to which an Investor  has entered  into a contract for
sale  prior to the  Investor's  receipt  of a notice  from  the  Company  of the
happening  of any  event of the kind  described  in  Section  3(f) or the  first
sentence of 3(e) and for which the Investor has not yet settled.

         5.       EXPENSES OF REGISTRATION.

         All reasonable expenses,  other than sales or brokerage commissions and
legal fees and disbursements of counsel to the Investor,  incurred in connection
with  registrations,  filings or  qualifications  pursuant  to Sections 2 and 3,
including,  without  limitation,  all registration,  listing and  qualifications
fees,  printers and accounting  fees, and fees and  disbursements of counsel for
the Company, shall be paid by the Company.

         6.       INDEMNIFICATION


<PAGE>


         a. To the fullest  extent  permitted  by law,  the Company  shall,  and
hereby does, indemnify,  hold harmless and defend the Investor,  each Person, if
any, who controls the Investor, the members, the directors,  officers, partners,
employees, agents,  representatives of the Investor and each Person, if any, who
controls  the  Investor  within the  meaning  of the 1933 Act or the  Securities
Exchange  Act of 1934,  as  amended  (the "1934  Act")  (each,  an  "Indemnified
Person"), against any losses, claims, damages,  liabilities,  judgments,  fines,
penalties,  charges,  costs,  attorneys'  fees,  amounts paid in  settlement  or
expenses, joint or several, (collectively,  "Claims") incurred in investigating,
preparing  or  defending  any  action,   claim,   suit,   inquiry,   proceeding,
investigation  or appeal  taken  from the  foregoing  by or before  any court or
governmental,  administrative  or  other  regulatory  agency,  body or the  SEC,
whether pending or threatened,  whether or not an indemnified party is or may be
a party thereto ("Indemnified Damages"), to which any of them may become subject
insofar  as such  Claims  (or  actions  or  proceedings,  whether  commenced  or
threatened,  in respect  thereof) arise out of or are based upon: (i) any untrue
statement or alleged  untrue  statement of a material  fact in the  Registration
Statement,  any  New  Registration  Statement  or any  post-effective  amendment
thereto  or in any  filing  made in  connection  with the  qualification  of the
offering  under the securities or other "blue sky" laws of any  jurisdiction  in
which Registrable Securities are offered ("Blue Sky Filing"), or the omission or
alleged  omission  to state a material  fact  required  to be stated  therein or
necessary  to make the  statements  therein  not  misleading,  (ii)  any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in any
preliminary  prospectus if used prior to the effective date of such registration
statement, or contained in the final prospectus (as amended or supplemented,  if
the Company files any amendment  thereof or supplement  thereto with the SEC) or
the omission or alleged omission to state therein any material fact necessary to
make the statements made therein,  in light of the circumstances under which the
statements  therein were made,  not  misleading,  (iii) any violation or alleged
violation  by the  Company  of the  1933  Act,  the 1934  Act,  any  other  law,
including,  without  limitation,  any  state  securities  law,  or any  rule  or
regulation  thereunder  relating  to  the  offer  or  sale  of  the  Registrable
Securities  pursuant  to the  Registration  Statement  or any  New  Registration
Statement or (iv) any material  violation of this  Agreement (the matters in the
foregoing  clauses (i)  through  (iv) being,  collectively,  "Violations").  The
Company shall, subject to Section 6(d) reimburse each Indemnified Person for any
legal fees or other  expenses  reasonably  incurred by them in  connection  with
investigating  or  defending  any such  Claim.  Notwithstanding  anything to the
contrary  contained  herein,  the  indemnification  agreement  contained in this
Section 6(a):  (i) shall not apply to a Claim by an  Indemnified  Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity
with information  furnished in writing to the Company by such Indemnified Person
expressly  for  use in  connection  with  the  preparation  of the  Registration
Statement,  any New  Registration  Statement  or any such  amendment  thereof or
supplement  thereto, if such prospectus was timely made available by the Company
pursuant to Section 3(c) or Section 3(e);  (ii) with respect to any  preliminary
prospectus,  shall not inure to the benefit of any Indemnified  Person from whom
the person  asserting a Claim  purchased  the  Registrable  Securities  that are
offered for sale by the preliminary  prospectus (or to the benefit of any person
controlling  such person) if the untrue  statement or omission of material  fact
contained in the preliminary prospectus was corrected in the prospectus, as then
amended or  supplemented,  if such  prospectus  was timely made available by the
Company pursuant to Section 3(c) or Section 3(e), and the Indemnified Person was
promptly advised in writing not to use the incorrect prospectus prior to the use
giving rise to a violation and such  Indemnified  Person,  notwithstanding  such
advice,  used it; (iii) shall not be available to the extent such Claim is based
on a  failure  of the  Investor  to  deliver  or to  cause to be  delivered  the
prospectus  made  available by the Company,  if such  prospectus was timely made
available  by the Company  pursuant to Section  3(c) or Section  3(e);  and (iv)
shall not apply to amounts paid in settlement of any Claim if such settlement is
effected  without the prior written consent of the Company,  which consent shall
not be  unreasonably  withheld.  Such  indemnity  shall remain in full force and
effect regardless of any  investigation  made by or on behalf of the Indemnified
Person and shall  survive the  transfer  of the  Registrable  Securities  by the
Investor pursuant to Section 9.


<PAGE>


         b.  In  connection   with  the   Registration   Statement  or  any  New
Registration  Statement,  the Investor shall, and hereby does,  indemnify,  hold
harmless  and defend,  to the same extent and in the same manner as is set forth
in Section 6(a), the Company,  each of its  directors,  each of its officers who
signs the Registration Statement or any New Registration Statement, each Person,
if any, who controls the Company  within the meaning of the 1933 Act or the 1934
Act  (collectively  and together with an  Indemnified  Person,  an  "Indemnified
Party"),  against  any  Claim or  Indemnified  Damages  to which any of them may
become subject,  under the 1933 Act, the 1934 Act or otherwise,  insofar as such
Claim or Indemnified  Damages arise out of or are based upon any  Violation,  in
each case to the extent,  and only to the extent,  that such Violation occurs in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by the Investor  expressly for use in connection with such  registration
statement;  and,  subject to Section 6(d), the Investor will reimburse any legal
or other expenses  reasonably  incurred by them in connection with investigating
or defending any such Claim;  provided,  however,  that the indemnity  agreement
contained in this Section 6(b) and the  agreement  with respect to  contribution
contained  in Section 7 shall not apply to  amounts  paid in  settlement  of any
Claim if such  settlement is effected  without the prior written  consent of the
Investor, which consent shall not be unreasonably withheld;  provided,  further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified  Damages as does not exceed the net proceeds to
the Investor as a result of the sale of Registrable  Securities pursuant to such
registration  statement.  Such  indemnity  shall remain in full force and effect
regardless of any  investigation  made by or on behalf of such Indemnified Party
and shall  survive the transfer of the  Registrable  Securities  by the Investor
pursuant to Section 9.

         c. Promptly after receipt by an Indemnified Person or Indemnified Party
under this Section 6 of notice of the  commencement  of any action or proceeding
(including  any  governmental  action or  proceeding)  involving  a Claim,  such
Indemnified  Person or Indemnified Party shall, if a Claim in respect thereof is
to be made against any  indemnifying  party under this Section 6, deliver to the
indemnifying  party  a  written  notice  of the  commencement  thereof,  and the
indemnifying  party shall have the right to  participate  in, and, to the extent
the indemnifying  party so desires,  jointly with any other  indemnifying  party
similarly  noticed,  to assume  control  of the  defense  thereof  with  counsel
mutually  satisfactory to the indemnifying  party and the Indemnified  Person or
the  Indemnified  Party,  as  the  case  may  be;  provided,  however,  that  an
Indemnified  Person or Indemnified  Party shall have the right to retain its own
counsel with the fees and expenses to be paid by the indemnifying  party, if, in
the  reasonable  opinion of counsel  retained  by the  indemnifying  party,  the
representation  by such counsel of the Indemnified  Person or Indemnified  Party
and the  indemnifying  party would be  inappropriate  due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party  represented  by such counsel in such  proceeding.  The  Indemnified
Party or Indemnified Person shall cooperate fully with the indemnifying party in
connection  with any  negotiation  or defense of any such action or claim by the
indemnifying  party and shall furnish to the indemnifying  party all information
reasonably  available  to the  Indemnified  Party or  Indemnified  Person  which
relates  to such  action  or  claim.  The  indemnifying  party  shall  keep  the
Indemnified  Party or  Indemnified  Person fully apprised at all times as to the
status of the defense or any settlement  negotiations  with respect thereto.  No
indemnifying  party shall be liable for any  settlement of any action,  claim or
proceeding  effected without its written consent,  provided,  however,  that the
indemnifying  party shall not  unreasonably  withhold,  delay or  condition  its
consent.  No  indemnifying  party shall,  without the consent of the Indemnified
Party or Indemnified Person,  consent to entry of any judgment or enter into any
settlement or other compromise  which does not include as an unconditional  term
thereof the giving by the  claimant or plaintiff  to such  Indemnified  Party or
Indemnified  Person of a release from all  liability in respect to such claim or
litigation.   Following   indemnification   as  provided  for   hereunder,   the
indemnifying party shall be subrogated to all rights of the Indemnified Party or
Indemnified  Person with  respect to all third  parties,  firms or  corporations
relating to the matter for which  indemnification  has been made. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action shall not relieve such indemnifying party of any
liability to the Indemnified  Person or Indemnified  Party under this Section 6,
except to the extent that the indemnifying party is prejudiced in its ability to
defend such action.

         d. The  indemnification  required  by this  Section  6 shall be made by
periodic  payments of the amount thereof during the course of the  investigation
or defense, as and when bills are received or Indemnified Damages are incurred.


<PAGE>


         e. The indemnity  agreements  contained  herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the  indemnifying  party or others,  and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

         7.       CONTRIBUTION.

         To  the  extent  any   indemnification  by  an  indemnifying  party  is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable  Securities guilty of fraudulent  misrepresentation
(within  the  meaning of Section  11(f) of the 1933 Act)  shall be  entitled  to
contribution  from any seller of  Registrable  Securities  who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds  received by
such seller from the sale of such Registrable Securities.

         8.       REPORTS AND DISCLOSURE UNDER THE SECURITIES ACTS.

         With a view to making  available  to the  Investor the benefits of Rule
144  promulgated  under the 1933 Act or any other  similar rule or regulation of
the SEC  that may at any  time  permit  the  Investor  to sell  the  Registrable
Securities to the public without  registration  ("Rule 144"), the Company agrees
to:

         a.  make and keep  public  information  available,  as those  terms are
understood and defined in Rule 144;

         b. file with the SEC in a timely manner all reports and other documents
required  of the  Company  under  the  1933  Act and the 1934 Act so long as the
Company remains subject to such  requirements and the filing of such reports and
other documents is required for the applicable provisions of Rule 144; and

         c.  furnish to the Investor so long as the  Investor  owns  Registrable
Securities,  promptly upon request,  (i) a written statement by the Company that
it has complied with the reporting and or disclosure provisions of Rule 144, the
1933 Act and the 1934 Act,  (ii) a copy of the most recent  annual or  quarterly

Company,  and (iii) such other  information  as may be  reasonably  requested to
permit  the  Investor  to sell  such  securities  pursuant  to Rule 144  without
registration.

hereby  irrevocably  waives personal  service of process and consents to process
being served in any such suit, action or proceeding by mailing a copy thereof to
such party at the address for such notices to it under this Agreement and agrees

Re: [__________]

Ladies and Gentlemen:

         We are counsel to UNIGENE  LABORATORIES,  INC., a Delaware  corporation
(the  "Company"),  and have  represented  the  Company in  connection  with that
certain Common Stock Purchase Agreement (the "Purchase  Agreement") entered into
by and among the Company and Fusion Capital Fund II, LLC (the "Holder") pursuant
to which the  Company has agreed to issue to the Holder up to Twenty One Million
Dollars  ($21,000,000)  of the Company's Common Stock, par value $0.01 per share
(the "Common  Stock") (the "Purchase  Shares"),  in accordance with the terms of
the  Purchase  Agreement,  and (ii) the Company  issued to the Holder  2,000,000
shares of Common Stock (the "Commitment  Shares").  Pursuant to the Common Stock
Purchase  Agreement,  the  Company  also has issued to the Buyer a warrant  (the
"Warrant")  granting the Buyer the right to purchase from the Company  1,000,000
shares  of  Common  Stock  (the  "Warrant  Shares").  Pursuant  to the  Purchase
Agreement,  the Company also has entered into a  Registration  Rights  Agreement
with the Holder  (the  "Registration  Rights  Agreement")  pursuant to which the
Company agreed, among other things, to register the Purchase Shares, the Warrant
Shares and the  Commitment  Shares under the  Securities Act of 1933, as amended
(the  "1933  Act").  In  connection  with the  Company's  obligations  under the
Purchase Agreement and the Registration Rights Agreement, on _____________,  the
Company  filed  a  Registration  Statement  (File  No.  333-_____________)  (the
"Registration  Statement")  with the  Securities  and Exchange  Commission  (the
"SEC") relating to the sale of the Purchase  Shares,  the Warrant Shares and the
Commitment Shares.

         In connection  with the  foregoing,  we advise you that a member of the
SEC's  staff has  advised  us by  telephone  that the SEC has  entered  an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF  EFFECTIVENESS]  on [ENTER DATE OF  EFFECTIVENESS]  and we have no knowledge,
after  telephonic  inquiry of a member of the SEC's  staff,  that any stop order
suspending its  effectiveness  has been issued or that any  proceedings for that
purpose are pending before,  or threatened by, the SEC and the Purchase  Shares,
the Warrant  Shares and the  Commitment  Shares are available for sale under the
1933 Act pursuant to the Registration Statement.

         The Buyer has  confirmed it shall comply with all  securities  laws and
regulations   applicable  to  it  including   applicable   prospectus   delivery
requirements  upon sale of the  Commitment  Shares,  the  Warrant  Shares or the
Purchase Shares.

                                               Very truly yours,
                                               [Company Counsel]


                                               By:____________________
