                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT  ("Agreement") is entered into as of
March 12, 1996, by and among UNIGENE LABORATORIES, INC., a Delaware corporation,
("Company"),  Swartz Investments,  LLC., a Georgia limited liability corporation
("Swartz  Investments")  and the  subscribers  ("Subscribers")  to the Company's
offering ("Offering") of up to $9,080,000 of Debentures pursuant to Regulation S
Subscription  Agreements  between the Company and the  Subscribers  of even date
herewith ("Subscription Agreement").

                  1.       Definitions. For purposes of this Agreement:

                  (a) The terms  "register",  "registered,"  and  "registration"
refer  to a  registration  effected  by  preparing  and  filing  a  registration
statement or similar  document in compliance with the Securities Act of 1933, as
amended (the "Act"),  and the declaration or ordering of  effectiveness  of such
registration statement or document;

                  (b) The term  "Registrable  Securities"  means  the  shares of
Common Stock issuable or issued upon (i) conversion of the Debentures  issued to
Subscribers in the Offering and (ii) exercise of the Warrant; provided, however,
that (x) after the expiration of the Restricted  Period,  shares of Common Stock
obtainable on conversion of the Debentures (in whole or in part),  and (y) after
two years from the date of this Agreement,  shares of Common Stock obtainable on
exercise of the Warrant (the "Warrant Shares"), shall not constitute Registrable
Securities,  if  those  shares  of  Common  Stock  may  be  resold  in a  public
transaction  without  registration  under the Act,  including without limitation
pursuant to Rule 144 under the Act.  Upon request of any Holders of Common Stock
issued or issuable upon conversion of the Debentures or exercise of the Warrant,
the Company shall cause legal counsel,  reasonably acceptable to such Holder, to
issue an opinion addressed to the holders, stating that such Common Stock may be
sold without  registration  and without  restriction  on resale under the Act as
described in the provisions of the immediately  preceding sentence,  in form and
substance reasonably satisfactory to such Holder.

                  (c) The  number  of  shares of  "Registrable  Securities  then
outstanding"  shall be  determined by the number of shares of Common Stock which
have been issued or are issuable upon  conversion of the Debentures and exercise
of the Warrant at the time of such determination;

                  (d) The term  "Holder"  means any person  owning or having the
right to acquire Registrable Securities or any permitted assignee thereof; and

                  (e) The term  "Warrant"  means the  warrant  granted to Swartz
Investments in connection with the Offering.

                  (f) "Restricted  Period" has the meaning ascribed to that term
in the Subscription Agreement.

                  2.       Demand Registration.

                  (a) At any  time  beginning  after  the end of the  Restricted
Period,  the  Holders of  Registrable  Securities  obtained or  obtainable  upon
conversion  of  at  least  25%  in  principal  amount  of  the  Debentures  then
outstanding  ("Initiating  Holders") may notify the Company in writing that they
demand that the Company file a registration statement under the Act covering the
registration of all of the Registrable  Securities then outstanding  (other than
Registrable  Securities  held by any  Holder  who does  not want to be  included
therein).  Upon receipt of such notice, the Company shall, within ten (10) days,
give  written  notice of such  request to all Holders and shall,  subject to the
limitations of subsection 2(b), file within 60 days of receipt of such request a
registration  statement  to  effect  the  registration  under  the  Act  of  all
Registrable Securities which the Holders request, by notice given to the Company
within (10) days of receipt of the Company's notice, and use its best efforts to
cause such  registration  statement  to become  effective as soon as possible (a
"Demand  Registration").  The Company may include in such registration statement
any other  securities of the Company  which the holders  thereof are entitled to
have so included  pursuant to any agreement entered into by the Company prior to
the date hereof (the "Additional Shares").

                  (b)  If  the  Initiating  Holders  intend  to  distribute  the
Registrable  Securities  covered by their  request by means of an  underwriting,
they shall so advise the  Company as a part of their  request  made  pursuant to
this Section 2 and the Company  shall  include such  information  in the written
notice referred to in subsection 2(a). In such event, the right of any Holder to
include his  Registrable  Securities in such  registration  shall be conditioned
upon such Holder's  participation in such underwriting and the inclusion of such
Holder's  Registrable  Securities  covered by the registration  statement in the
underwriting  (unless otherwise mutually agreed by a majority in interest of the
Initiating  Holders and such Holder).  All Holders proposing to distribute their
securities  through  such  underwriting  shall  (together  with the  Company  as
provided in subsection  6(f)) enter into an underwriting  agreement in customary
form with the  underwriter or underwriters  selected for such  underwriting by a
majority in interest of the Initiating Holders, and reasonably acceptable to the
Company.

                  (c) The  Company  is  obligated  to  effect  only  one  Demand
Registration  pursuant to Section 2 of this  Agreement.  The  Company  agrees to
include all  Registrable  Securities  held by all  Holders in such  registration
statement;  provided  that,  in the event  that (i) the  Registrable  Securities
covered by such  registration  statement  are to be  distributed  pursuant to an
underwriting  and (ii) the  managing  underwriter  determines,  and  advises the
Company in writing, that marketing factors require a limitation on the number of
shares  (including   Additional   Shares)  to  be  underwritten,   the  managing
underwriter  may  require  the  exclusion  from the  underwriting  of the excess
shares,  with  the  shares  to  be  excluded  allocated  among  the  Registrable
Securities and all  Additional  Shares in respect of which the exclusion of such
Additional Shares on any other basis would violate the contractual rights of the
holders of such  Additional  Shares,  in the proportion  that the number of such
Registrable  Securities or Additional  Shares which each holder thereof seeks to
register  bears to the total number of  Registrable  Securities  and  Additional
Shares  sought to be  included  by all  holders of  Registrable  Securities  and
Additional  Shares.  In the event the Company  breaches  its  obligation  of the
preceding sentence, or Registrable Securities are excluded from the registration
statement  by reason of the  proviso  thereof,  any  Holders of the  Registrable
Securities  which were not  included  in such  registration  statement  shall be
entitled to a Demand Registration for such excluded securities on the same terms
as the Demand Registration described in this Agreement.

                  (d)  The  Company  is  not   obligated   to  effect  a  Demand
Registration  under this Section 2 if, in the written  opinion of counsel to the
Company reasonably acceptable to the person or persons from whom written request
for registration has been received (and  satisfactory to the Company's  transfer
agent to permit the  transfer),  registration  under the Act is not required for
the  immediate   public  transfer  of  the  Registrable   Securities,   with  no
restrictions on resale,  pursuant to Rule 144 or any other applicable  exemption
from registration.

                  (e) The Company  represents  that it is eligible to effect the
registration   contemplated  hereby  on  Form  S-3  and  will  use  commercially
reasonable efforts to maintain such eligibility.

                  3. Piggyback  Registration.  If (but without any obligation to
do  so)  the  Company  proposes  to  register  (including  for  this  purpose  a
registration  effected by the Company for  shareholders  other than the Holders)
any of its Common Stock under the Act in connection  with the public offering of
such  securities  (other  than a  registration  relating  solely  to the sale of
securities to participants in a Company  employee benefit plan or a registration
on  Form  S-4  promulgated  under  the  Act or any  successor  or  similar  form
registering stock issuable upon a reclassification,  upon a business combination
involving an exchange of securities or upon an exchange  offer for securities of
the issuer or another  entity),  the Company shall, at such time,  promptly give
each Holder written  notice of such  registration.  Upon the written  request of
each  Holder  given  within  ten (10) days after  mailing of such  notice by the
Company,  which request shall state the intended  method of  disposition of such
shares by such Holder,  the Company shall cause to be  registered  under the Act
all of the  Registrable  Securities  that each such Holder has  requested  to be
registered  (a "Piggyback  Registration").  The Company may elect not to proceed
with, or suspend the effectiveness  of, a Piggyback  Registration at any time in
its sole discretion and without prior consultation with any Holder.

                  4.       Limitation on Obligations to Register.

                  (a) In the case of a Piggyback Registration on an underwritten
public  offering by the Company,  if the  managing  underwriter  determines  and
advises in writing  that the  inclusion  in the  registration  statement  of all
Registrable  Securities  proposed  to  be  included  would  interfere  with  the
successful  marketing of the  securities  proposed to be offered and sold by the
Company, then the number of such Registrable Securities,  if any, to be included
in the registration statement as determined by the managing underwriter shall be
allocated  among all Holders who had requested  Piggyback  Registration,  in the
proportion  that the number of  Registrable  Securities  which each such Holder,
including  Swartz  Investments,  seeks to register  bears to the total number of
Registrable  Securities  sought to be included by all Holders,  including Swartz
Investments.

                  (b)  Notwithstanding  anything  to the  contrary  herein,  the
Company shall have the right (i) to defer the filing of a registration statement
(or any amendment  thereto) or any request for  acceleration of effectiveness of
any Demand Registration and (ii) after effectiveness,  to suspend  effectiveness
of any such registration statement,  if, in the good faith judgment of the board
of directors of the Company and upon the advice of counsel to the Company,  such
delay in filing or requesting  acceleration of  effectiveness or such suspension
of effectiveness  is necessary in light of the existence of material  non-public
information  (financial or otherwise)  concerning the Company, the disclosure of

which at the time is not, (A) otherwise  required and (B) in the best  interests
of the Company;  provided  however that the Company will use its best efforts to
terminate  such delay or  suspension as soon as  practicable  and, in any event,
will not delay  effectiveness  of such Demand  Registration  for more than three
months  from the date of the  demand or suspend  effectiveness  for more than 60
days,  unless  it is  then  engaged  in an  acquisition  that  would  make  such
registration  impracticable,  in  which  case it will use its  best  efforts  to
eliminate such impracticability as soon as possible.

                  5.  Obligations  to  Increase  Available  Shares.  If  after a
registration statement is filed pursuant to Section 2 the shares of Common Stock
issuable  upon the  conversion  of the  Debentures  is  change  by reason of the
adjustment of the Conversion Rate, the number of Registrable  Securities covered
by the registration statement shall be proportionally adjusted. If required, the
Company  shall amend that  registration  statement,  or file a new  registration
statement, or both, so as to cover such additional Registrable  Securities.  The
Company  shall  use   commercially   reasonable   efforts  to  effect  such  new
registration within ninety days.

                  6.  Obligations of the Company.  Whenever  required under this
Agreement to effect the registration of any Registrable Securities,  but subject
to the  limitations  on the  obligations  of the Company set forth  herein,  the
Company shall, as expeditiously as reasonably possible:

                  (a)  Prepare  and file with the SEC a  registration  statement
with respect to such  Registrable  Securities  and use  commercially  reasonable
efforts to cause such registration statement to become effective.

                  (b  Prepare  and  file  with  the  SEC  such   amendments  and
supplements to such registration statement and the prospectus used in connection
with  such  registration  statement  as may be  necessary  to  comply  with  the
provisions  of the  Act  with  respect  to the  disposition  of the  Registrable
Securities covered by such registration statement.

                  (c) With respect to any Demand Registration,  use commercially
reasonable efforts to keep such registration statement effective for a period of
at least 180 days or, if earlier  until the  Holders of  Registrable  Securities
covered by such registration statement have completed the distribution described
in the registration statement.

                  (d)  Furnish  to the  Holders  such  numbers  of  copies  of a
prospectus,  including a preliminary prospectus,  as they may reasonably request
in order to facilitate the disposition of Registrable  Securities covered by the
registration statement.

                  (e)  Use  commercially  reasonable  efforts  to  register  and
qualify the Registrable  Securities covered by such registration statement under
such other  securities or Blue Sky laws of such of the United States as shall be
reasonably  requested by the Holders of the  Registrable  Securities  covered by
such registration statement,  provided that the Company shall not be required in
connection  therewith or as a condition  thereto to qualify to do business or to
file a general consent to service of process in any such states.

                  (f) In the event of any underwritten  public  offering,  enter
into and perform its  obligations  under an  underwriting  agreement  that is in
usual and customary form with the managing  underwriter  of such offering.  Each
Holder  participating in such underwriting shall also enter into and perform its
obligations under such underwriting agreement.

                  (g) Notify each Holder of  Registrable  Securities  covered by
such  registration  statement at any time when a prospectus  relating thereto is
required to be delivered under the Act of the happening of any event as a result
of which the prospectus,  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 not  misleading  in the light of the
circumstances then existing.

                  (h)  Furnish,   at  the  request  of  any  Holder   requesting
registration of Registrable  Securities pursuant to this Agreement,  on the date
that  Registrable  Securities  are  delivered  to the  underwriters  for sale in
connection with a registration  pursuant to this Agreement,  if such Registrable
Securities  are  being  sold  through  underwriters,  or,  if  such  Registrable
Securities  are not  being  sold  through  underwriters,  on the  date  that the
registration statement with respect to such securities becomes effective, (i) an
opinion,  dated such date,  of the  counsel  representing  the  Company  for the
purposes of such registration,  in form and substance as is customarily given to
underwriters in an underwritten public offering,  addressed to the underwriters,
if any,  and to the  Holders of such  Registrable  Securities  and (ii) a letter
dated  such date,  from the  independent  certified  public  accountants  of the
Company,  in form and substance as is customarily  given by  independent  public
accountants to underwriters in an underwritten public offering, addressed to the
underwriters, if any, and to the Holders of such Registrable Securities.

                  (i)  Use  commercially  reasonable  efforts  to  maintain  the
listing of the Common Stock on NASDAQ Small Cap Market,  NASDAQ  National Market
System or a national  securities  exchange for as long as any of the Registrable
Securities are still outstanding.

                  7. Furnish  Information.  It shall be a condition precedent to
the  obligations  of the Company to take any action  pursuant to this  Agreement
that the selling Holders shall furnish to the Company such information regarding
themselves,  the Registrable Securities held by them, and the intended method of
disposition of such  securities as shall be required to effect the  registration
of  their  Registrable  Securities  or to  determine  that  registration  is not
required by reason of the availability of Rule 144 or other applicable provision
of the Act.

                  8.       Future Grants.

                  (a) The Company  represents  and  warrants to the Holders that
the number of securities  constituting  Additional Shares are the 100,000 shares
of Common Stock initially  issuable upon the exercise of certain warrants issued
by the Company prior to the date hereof  (warrants for 50,000 shares were issued
on March 15, 1995 and warrants for 50,000  shares were issued on April 15, 1995,
collectively  the "Existing  Warrants") and such additional  number of shares of
Common Stock as may be issued, pursuant to certain anti-dilution  provisions set
forth in the Existing Warrants, upon exercise thereof.

                  (b) During the period commencing on the date hereof and ending
on the date of termination of this Agreement, the Company shall not grant to any
person  registration  rights with respect to Common Stock that are senior to the
registration rights granted herein.

                  9. Expenses of Demand Registration.  All expenses,  other than
underwriting   discounts   and   commissions,   incurred  in   connection   with
registrations,  filings or  qualifications  pursuant  to  Section  2,  including
(without limitation) all registration,  filing and qualification fees, printers'
and accounting  fees,  fees and  disbursements  of counsel for the Company,  and
including the reasonable fees and disbursements incurred of only one counsel for
the selling Holders,  shall be borne by the Company;  provided,  however, if the
registration request is subsequently  withdrawn at the request of the Holders of
a majority of the Registrable Securities to be registered, the Company shall not
be  required  to pay for  any  expenses  of any  registration  proceeding  begun
pursuant  to  Section  2 (in  which  case all  Holders  who had  requested  such
registration  shall by jointly and  severally  liable for such  expenses and the
Holders of  Registrable  Securities  shall  have no  further  rights to a Demand
Registration);   provided  further,  however,  that  if  at  the  time  of  such
withdrawal,  the  Holders  have  learned  of a  material  adverse  change in the
condition,  business,  or  prospects of the Company from that which was publicly
known at the time of their  request,  then the Holders  shall not be required to
pay any of such expenses and shall retain their rights pursuant to Section 2.

                  10. Expenses of Company  Registration.  The Company shall bear
and pay all expenses  incurred in connection  with any  registration,  filing or
qualification  of  Registrable  Securities  with  respect  to the  registrations
pursuant  to  Section 3 for each  Holder,  including  (without  limitation)  all
registration,  filing,  and  qualification  fees,  printers and accounting  fees
relating  or  apportionable  thereto  (and  including  the  reasonable  fees and
disbursements  incurred by only one counsel for the selling Holders  selected by
them), but excluding underwriting discounts and commissions relating to the sale
of Registrable Securities.

                  11.  Indemnification.  In the event any Registrable Securities
are included in a registration statement under this Agreement:


                  (a) To the extent permitted by law, the Company will indemnify
and hold harmless each "Holder Indemnified Person" (defined for purposes of this
Section 11 as each Holder of registrable securities included in the registration
statement,  the  officers  and  directors  of each such  Holder  acting in their
capacity as such,  any  underwriter  (as defined in the Act) for such Holder and
each person, if any, who controls such Holder or underwriter  within the meaning
of the Act or the Securities Exchange Act of 1934, as amended (the "1934 Act")),
against any losses, claims, damages, expenses, or liabilities (joint or several)
("Losses") to which they may become subject under the Act, the 1934 Act or other
federal or state law,  insofar as such  Losses (or  actions in respect  thereof)
arise out of or are based upon any of the  following  statements,  omissions  or
violations  (collectively a "Violation"):  (i) any untrue statement,  or alleged
untrue  statement of a material fact contained in such  registration  statement,
including any preliminary  prospectus or final prospectus  contained  therein or
any amendments or supplements thereto,  (ii) the omission,  or alleged omission,
to state therein a material fact required to be stated therein,  or necessary to
make the  statements  therein  not  misleading,  or (iii) any  violation  by the
Company  of the Act,  the 1934  Act,  any  state  securities  law or any rule or
regulation  promulgated under the Act, the 1934 Act or any state securities law;
and the Company will reimburse each such Holder Indemnified Person for any legal
or other expenses  reasonably  incurred by them in connection with investigating
or defending  any such Loss or action;  provided,  however,  that the  indemnity
agreement  contained in this subsection 11(a) shall not apply to amounts paid in

settlement of any such Loss or action if such settlement is effected without the
prior written  consent of the Company (which  consent shall not be  unreasonably
withheld), nor shall the Company be liable in any such case for any such Loss or
action to the extent  that it arises out of or is based upon a  Violation  which
occurs in either (i) in reliance upon and in conformity with written information
furnished  expressly for use in connection  with such  registration  by any such
Holder  Indemnified  Person  or  any  of  its  directors,  officers,  agents  or
affiliates or (ii) based upon a prospectus which included a Violation, after the
Company has advised the Holder not to sell pursuant to such prospectus,  and has
made  available  an  amended  or  supplemental  prospectus  that  corrects  such
Violation.

                  (b) To the extent  permitted by law,  each  selling  Holder of
Registrable Securities included in the registration statement will indemnify and
hold harmless the "Company Indemnified Persons" (defined for the purpose of this
Section 11 as the Company,  each of its officers and directors in their capacity
as such, each person, if any, who controls the Company within the meaning of the
Act  or the  1934  Act,  any  underwriter  and  any  person  who  controls  such
underwriter  within the meaning of the Act or the 1934 Act and any other  Holder
Indemnified Person selling securities in such registration  statement),  against
any Loss (joint or several) to which the Company or any such director,  officer,
controlling  person, or underwriter or controlling  person, or other such Holder
Indemnified  Person may  become  subject,  under the Act,  the 1934 Act or other
federal or state law, insofar as such Loss (or actions in respect thereto) 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 by such Holder or any of its directors,  officers,
employees,  agents  or  affiliates  expressly  for use in  connection  with such
registration;  and each such Holder will  reimburse any legal or other  expenses
reasonably  incurred by the Company and any such Company  Indemnified  Person in
connection with  investigating  or defending any such Loss or action;  provided,
however,  that the indemnity  agreement contained in this subsection 11(b) shall
not  apply to  amounts  paid in  settlement  of any such  Loss or action if such
settlement  is effected  without the consent of the Holder,  which consent shall
not be unreasonably  withheld;  provided,  that, in no event shall any indemnity
under this subsection 11(b) exceed the gross proceeds from the offering received
by such Holder.

                  (c) Promptly after receipt by an indemnified  party under this
Section  11  of  notice  of  the  commencement  of  any  action  (including  any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any  indemnifying  party under this Section 11, 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  the  defense  thereof  with  counsel  mutually
satisfactory to the parties; provided,  however, that an indemnified party shall
have the right to retain its own counsel,  with the reasonably incurred fees and
expenses  to be  paid  by the  indemnifying  party,  if  representation  of such
indemnified  party by the counsel  retained by the  indemnifying  party would be
inappropriate  due to actual  or  potential  differing  interests  between  such
indemnified  party and any  other  party  represented  by such  counsel  in such
proceeding.  The failure to deliver  written  notice to the  indemnifying  party
within a reasonable time of the commencement of any such action,  if prejudicial
to its ability to defend such action,  shall relieve such indemnifying  party of
any liability to the indemnified party under this Section 11.

                  (d) The  obligations  of the Company  and  Holders  under this
Section  11  shall  survive  the  completion  of  any  offering  of  Registrable
Securities in a registration statement under this Agreement, and otherwise.

                  12. Reports Under Securities Exchange Act of 1934. With a view
to making  available to the Holders the benefits of Rule 144  promulgated  under
the  Act  and any  other  rule or  regulation  of the  Securities  and  Exchange
Commission ("SEC") that may at any time permit a Holder to sell shares of Common
Stock of the Company to the public without  registration,  the Company agrees to
use commercially reasonable efforts to:

                  (a) whether or not the  Company is  required  to file  reports
required  by Section  13(a) of the 1934 Act,  make and keep  public  information
available,  as those  terms are  understood  and defined in SEC Rule 144, at all
times;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

                  (c)  furnish to any  Holder,  so long as the  Holder  owns any
Registrable  Securities,  forthwith upon request (i) a written  statement by the
Company,  if true,  that it has  complied  with the  reporting  requirements  of
Section 13(a) or 15(d) of the 1934 Act, (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company  under  Section 13(a) or 15(d) of the 1934 Act, and (iii) such other
information as may be reasonably requested in availing any Holder of any rule or
regulation  of the SEC which permits the selling of any  Registrable  Securities
without registration.

                  13.  Amendment of Registration  Rights.  Any provision of this
Agreement  may be  amended  and the  observance  thereof  may be waived  (either
generally   or  in  a   particular   instance   and  either   retroactively   or
prospectively),  only with the written consent of the Company and the Holders of
a majority of the  Registrable  Securities  then  outstanding.  Any amendment or
waiver  effected in accordance  with this  paragraph  shall be binding upon each
Holder,  each future  Holder,  and the  Company;  provided  that no amendment or
waiver that  materially and adversely  affects the rights of any Holder shall be
effective against such Holder unless such Holder agrees thereto.

                  14.  Notices.  All notices  required or  permitted  under this
Agreement  shall be made in writing  signed by the party making the same,  shall
specify  the section  under this  Agreement  pursuant to which it is given,  and
shall be addressed if to (i) the Company at:  President,  Unigene  Laboratories,
Inc., 110 Little Falls Road,  Fairfield,  New Jersey 07004,  Telephone No. (201)
