 WHEREAS: 
  
 Subject to the terms and conditions set forth in this Agreement, the Company
wishes to sell to the Buyer, and the Buyer wishes to buy from the Company, 2,123,142 shares (the “Purchase Shares”) of the Company’s common stock, par value $0.01 per share (the “Common Stock”) for a purchase price of Three

 NOW THEREFORE, the Company and the Buyer hereby agree as follows: 
  
 1. PURCHASE OF COMMON STOCK. 
  
 Subject to the terms and conditions set forth in Sections 6, 7 and 9 below,
the Company hereby agrees to sell to the Buyer, and the Buyer hereby agrees to purchase from the Company, 2,123,142 Purchase Shares and the Warrant for an aggregate purchase price of Three Million Dollars ($3,000,000) on the Closing Date (as defined

 2. BUYER’S REPRESENTATIONS AND WARRANTIES. 
  
 The Buyer represents and warrants to the Company that as of the date hereof and as of the Closing Date: 
  
 (a) Investment Purpose. The Buyer is entering into this Agreement and
acquiring the Purchase Shares and the Warrant (the Purchase Shares, the Warrant and the Warrant Shares are collectively referred to herein as the “Securities”), for its own account for investment only and not with a view towards, or for
resale in connection with, the public sale or distribution thereof; provided however, by making the representations herein, the Buyer does not agree to hold any of the Securities for any minimum or other specific term. 

 (b) Accredited Investor Status. The Buyer is an “accredited investor” as that term is
defined in Rule 501(a)(3) of Regulation D. 
  
 (c) Reliance on
Exemptions. The Buyer understands that the Securities are being offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in
part upon the truth and accuracy of, and the Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Buyer set forth herein in order to determine the availability of such exemptions and
the eligibility of the Buyer to acquire the Securities. 
  
 (d)
Information. The Buyer has been furnished with all materials relating to the business, finances and operations of the Company and materials relating to the offer and sale of the Securities that have been reasonably requested by the Buyer,
including, without limitation, the SEC Documents (as defined in Section 3(f) hereof). The Buyer understands that its investment in the Securities involves a high degree of risk. The Buyer (i) is able to bear the economic risk of an investment in the
Securities including a total loss, (ii) has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the proposed investment in the Securities and (iii) has had an opportunity to ask
questions of and receive answers from the officers of the Company concerning the financial condition and business of the Company and others matters related to an investment in the Securities. Neither such inquiries nor any other due diligence
investigations conducted by the Buyer or its representatives shall modify, amend or affect the Buyer’s right to rely on the Company’s representations and warranties contained in Section 3 below. The Buyer has sought such accounting, legal
and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Securities. 
  
 (e) No Governmental Review. The Buyer understands that no United States federal or state agency or any other government or governmental agency has
passed on or made any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities. 
  
 (f) Transfer or Resale. The Buyer understands that except as provided
in the Registration Rights Agreement (as defined in Section 4(a) hereof): (i) the Securities have not been and are not being registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred
unless (A) subsequently registered thereunder or (B) an exemption exists permitting such Securities to be sold, assigned or transferred without such registration; (ii) any sale of the Securities made in reliance on Rule 144 may be made only in
accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the person through whom the sale is made) may be deemed to be an underwriter (as that term is
defined in the 1933 Act) may require compliance with some other exemption under the 1933 Act or the rules and regulations of the SEC thereunder; and (iii) neither the Company nor any other person is under any obligation to register the Securities
under the 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. 
  
 (g) Validity; Enforcement. This Agreement has been duly and validly authorized, executed and delivered on behalf of the Buyer and is a valid and
binding agreement of the Buyer enforceable against the Buyer in accordance with its terms, subject as to enforceability to general principles of equity and to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other
similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

 (h) Residency. The Buyer is a resident of the State of Illinois. 
  
 (i) No Prior Short Selling. The Buyer represents and warrants to the
Company that at no time prior to the date of this Agreement has any of the Buyer, its agents, representatives or affiliates engaged in or effected, in any manner whatsoever, directly or indirectly, any (i) “short sale” (as such term is
defined in Rule 3b-3 of the Securities Exchange Act of 1934, as amended (the “1934 Act”)) of the Common Stock or (ii) hedging transaction, which establishes a net short position with respect to the Common Stock.

contemplated hereby and thereby, including without limitation, the sale and issuance of the Purchase Shares and issuance of the Warrant issuable under this Agreement, have been duly authorized by the Company’s Board of Directors and no further
consent or authorization is required by the Company, its Board of Directors or its shareholders, (iii) this Agreement has been, and each other Transaction Document shall be on the Closing Date, duly executed and delivered by the Company and (iv)

remedies. The Board of Directors of the Company has approved the resolutions (the “Signing Resolutions”)

to make the statements therein, in light of the circumstances under which they were made, not misleading. As of their respective dates (except as they have been properly amended), the financial statements of the Company included in the SEC Documents
complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. Such financial statements have been prepared in accordance with generally accepted

Company’s Subsidiaries’ officers or directors in their capacities as such, which could reasonably be expected to have a Material Adverse Effect. A description of each action, suit, proceeding, inquiry or investigation before or by any
court, public board, government agency, self-regulatory organization or body which, as of the date of this Agreement, is pending or threatened in writing against or affecting the Company, the Common Stock or any of the Company’s Subsidiaries or

length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby. The Company further acknowledges that the Buyer is not acting as a financial advisor or fiduciary of the Company (or in any similar

contemplated hereby and thereby is merely incidental to the Buyer’s purchase of the Securities. The Company further represents to the Buyer that the Company’s decision to enter into the Transaction Documents has been based solely on the
independent evaluation by the Company and its representatives and advisors. 
  
 (j) No General Solicitation. Neither the Company, nor any of its affiliates, nor any person acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the

all material trademarks, trade names, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions, licenses, approvals, governmental authorizations, trade secrets and rights necessary to conduct their
respective businesses as now conducted. Except as set forth on Schedule 3(l), none of the Company’s material trademarks, trade names, service marks, service mark registrations, service names, patents, patent rights, copyrights, inventions,
licenses, approvals, government authorizations, trade secrets or other intellectual property rights have expired or terminated, or, by the terms and conditions thereof, are scheduled to expire or terminate within two years from the date of this
Agreement. The Company and its Subsidiaries do not have any knowledge of any infringement by the Company or its Subsidiaries of any material trademark, trade name rights, patents, patent rights, copyrights, inventions, licenses, service names,
service marks, service mark registrations, trade secret or other similar rights of others, or of any such development of similar or identical trade secrets or technical information by others and, except as set forth on Schedule 3(l), there is no
claim, action or proceeding being made or brought against, or to the Company’s knowledge, being threatened against, the Company or its Subsidiaries regarding trademark, trade name, patents, patent rights, invention, copyright, license, service

 (m) Environmental Laws. The Company and its Subsidiaries (i) are in compliance with any and all applicable foreign, federal, state and local laws
and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received all permits, licenses or other
approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval, except where, in each of the three foregoing
clauses, the failure to so comply could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect. 
  
 (n) Title. The Company and its Subsidiaries have good and marketable title in fee simple to all real property and good and marketable title to all
personal property owned by them which is material to the business of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as are described in Schedule 3(n) or such as do not materially
affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company and any of its
Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries.

  
 (o) Insurance. The Company and each of its Subsidiaries
are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are
engaged. Neither the Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be
necessary to continue its business at a cost that would not materially and adversely affect the condition, financial or otherwise, or the earnings, business or operations of the Company and its Subsidiaries, taken as a whole. 
  

 -7- 

 (p) Regulatory Permits. The Company and its Subsidiaries possess all material certificates,

 (q) Tax Status. The Company and each of its Subsidiaries has made or filed all federal and state income and all other material tax returns, reports and declarations required by any jurisdiction to which it is
subject (unless and only to the extent that the Company and each of its Subsidiaries has set aside on its books provisions reasonably adequate for the payment of all unpaid and unreported taxes) and has paid all taxes and other governmental
assessments and charges that are material in amount, shown or determined to be due on such returns, reports and declarations, except those being contested in good faith and has set aside on its books provision reasonably adequate for the payment of
all taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company
know of no basis for any such claim. 
  
 (r) Transactions With
Affiliates. Except as set forth on Schedule 3(r) and other than the grant or exercise of stock options disclosed on Schedule 3(c), none of the officers, directors, or employees of the Company is presently a party to any transaction with the
Company or any of its Subsidiaries (other than for services as employees, officers and directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of real or personal
property to or from, or otherwise requiring payments to or from any officer, director or such employee or, to the knowledge of the Company, any corporation, partnership, trust or other entity in which any officer, director, or any such employee has
an interest or is an officer, director, trustee or partner. 
  
 (s) Application of Takeover Protections. The Company and its board of directors have taken or will take prior to the Closing Date all necessary action, if any, in order to render inapplicable any control share acquisition, business
combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of Incorporation or the laws of the state of its incorporation which is or could become applicable to the
Buyer as a result of the transactions contemplated by this Agreement, including, without limitation, the Company’s issuance of the Securities and the Buyer’s ownership of the Securities. 
  
 (t) Foreign Corrupt Practices. To the knowledge of the Company,
neither the Company, nor any of its Subsidiaries, nor any director, officer, agent, employee or other person acting on behalf of the Company or any of its Subsidiaries has, in the course of its actions for, or on behalf of, the Company, used any
corporate funds for any unlawful contribution, gift, entertainment or other unlawful expenses relating to political activity; made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate
funds; violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended; or made any unlawful bribe, rebate, payoff, influence payment, kickback or other unlawful payment to any foreign or domestic

Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other person.

  
 (i) Publicity. The Buyer shall have the right to
approve before issuance any press releases or any other public disclosure (including any filings with the SEC) with respect to the transactions contemplated hereby; provided, however, that the Company shall be entitled, without the prior approval of
the Buyer, to make any press release or other public disclosure (including any filings with the SEC) with respect to such transactions as is required by applicable law and regulations (although the Buyer shall be consulted by the Company in
connection with any such press release or other public disclosure prior to its release and shall be provided with a copy thereof).

contemplated hereby. 
  
 (k) Termination. This Agreement
may be terminated only as follows: 
  
 (i) By the
Buyer any time an Event of Default exists without any liability or payment to the Company. However, if pursuant to or within the meaning of any Bankruptcy Law, the Company commences a voluntary case or any Person commences a proceeding against the
Company, a Custodian is appointed for the Company or for all or substantially all of its property, or the Company makes a general assignment for the benefit of its creditors, (any of which would be an Event of Default as described in Sections 9(g),
9(h) and 9(i) hereof) this Agreement shall automatically terminate without any liability or payment to the Company without further action or notice by any Person. 
  
 (ii) In the event that the Closing shall not have occurred on or before April 30, 2005, due to the failure
to satisfy any of the conditions set forth in Sections 6 and 7 above with respect to the Closing (and the nonbreaching party’s failure to waive such unsatisfied condition(s)), the nonbreaching party shall have the option to terminate this
Agreement at the close of business on such date or thereafter without liability of any party to any other party. 
  
 (iii) This Agreement shall automatically terminate on the date that the Buyer and its affiliates no longer hold any of the Purchase
Shares, the Warrant or any Warrant Shares, without any action or notice on the part of any party. 
  
 Except as set forth in Sections 11(k)(i) (in respect of an Event of Default under Sections 9(g), 9(h) and 9(i)) and 11(k)(iii), any termination of this Agreement pursuant to this Section 11(k) shall be effected by
written notice from the Company to the Buyer, or the Buyer to the Company, as the case may be, setting forth the basis for the termination hereof. The representations and warranties of the Company and the Buyer contained in Sections 2 and 3 hereof,
the indemnification provisions set forth in Section 8 hereof and the agreements and covenants set forth in Section 11, shall survive the Closing and any termination 

  

 -17- 

 
of this Agreement. No termination of this Agreement shall affect the Company’s or the Buyer’s rights or obligations under the Registration Rights
Agreement or the Warrant each of which shall survive any such termination of this Agreement. 
  
 (l) No Financial Advisor, Placement Agent, Broker or Finder. The Company represents and warrants to the Buyer that it has not engaged any financial advisor, placement agent, broker or finder in connection with
the transactions contemplated hereby. The Buyer represents and warrants to the Company that it has not engaged any financial advisor, placement agent, broker or finder in connection with the transactions contemplated hereby.

be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 
  
 (n) Remedies, Other Obligations, Breaches and Injunctive Relief. The Buyer’s remedies provided in this Agreement shall be cumulative and in
addition to all other remedies available to the Buyer under this Agreement, at law or in equity (including a decree of specific performance and/or other injunctive relief), no remedy of the Buyer contained herein shall be deemed a waiver of
compliance with the provisions giving rise to such remedy and nothing herein shall limit the Buyer’s right to pursue actual damages for any failure by the Company to comply with the terms of this Agreement. The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to the Buyer and that the remedy at law for any such breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the Buyer
shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the necessity of showing economic loss and without any bond or other security being required. 
  
 (o) Changes to the Terms of this Agreement. This Agreement and any
provision hereof may only be amended by an instrument in writing signed by the Company and the Buyer. The term “Agreement” and all reference thereto, as used throughout this instrument, shall mean this instrument as originally executed, or
if later amended or supplemented, then as so amended or supplemented. 
  
 (p) Enforcement Costs. If: (i) this Agreement is placed by the Buyer in the hands of an attorney for enforcement or is enforced by the Buyer through any legal proceeding; or (ii) an attorney is retained to represent the Buyer in any
bankruptcy, reorganization, receivership or other proceedings affecting creditors’ rights and involving a claim under this Agreement; or (iii) an attorney is retained to represent the Buyer in any other proceedings whatsoever arising out of
entering into, performance under or enforcement of, this Agreement, then the Company shall pay to the Buyer, as incurred by the Buyer, all reasonable costs and expenses including attorneys’ fees incurred in connection therewith, in addition to
all other amounts due hereunder. 
  
 (q) Failure or Indulgence
Not Waiver. No failure or delay in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise
thereof or of any other right, power or privilege.

 EXHIBIT A 
  
 FORM OF COMPANY COUNSEL OPINION 
  
 Ladies and Gentlemen: 
  
 We have acted as special counsel to Unigene Laboratories, Inc., a Delaware corporation (the “Company”), in connection with the execution and delivery by the
Company of the Common Stock Purchase Agreement, dated April     , 2005 between Fusion Capital Fund II, LLC (“Fusion”) and the Company (the “Purchase Agreement”). We are delivering this opinion to you
pursuant to Section 7(d) of the Purchase Agreement. Capitalized terms used herein without definition have the respective meanings ascribed to such terms in the Purchase Agreement. 
  
 We have examined the Purchase Agreement, the Registration Rights Agreement between Fusion and the Company dated April
    , 2005 (the “Registration Rights Agreement” and together with the Purchase Agreement, the “Transaction Documents”), and the Warrant issued by the Company, dated April
    , 2005 (the “Warrant”). 
  
 We have made
such investigation and examined such other documents, corporate records, instruments and matters of law as we have deemed necessary or appropriate for the purposes of this opinion, including copies of the Company’s Certificate of Incorporation,
as amended (the “Certificate of Incorporation”), copies of the Company’s bylaws, as amended, certain resolutions adopted by the Board of Directors of the Company, a Certificate of Good Standing issued by the Secretary of State of the
State of Delaware dated March 23, 2005, [and a Certificate of Good Standing issued by the Department of Treasury of the State of New Jersey dated April     , 2005] with respect to the Company. In rendering the opinions
hereinafter set forth, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents
submitted to us as certified, conformed or photostatic copies and the authenticity of the originals of such documents. As to matters of fact relevant to the opinions expressed herein, we have relied exclusively, without independent investigation or
verification, upon, and have assumed the accuracy of, representations of the Company in the Transaction Documents and the Warrant and on certificates of officers of the Company and of public officials. 
  
 In rendering the opinion set forth in paragraph 4, we have also assumed that: (i) Fusion is
duly formed, validly existing and in good standing under the laws of the jurisdiction of its formation and (ii) Fusion has the requisite power and authority and has taken the action necessary to consummate the transactions contemplated by the
Transaction Documents. 
  
 Our opinions set forth herein are based only on our
consideration of those statutes, rules, regulations and judicial decisions that, in our experience, are normally applicable to, or normally relevant in connection with, a transaction of the type contemplated by the Transaction Documents and in the
Warrant. Whenever our opinion with respect to the existence or absence of facts is indicated to be based on our knowledge or awareness, we are referring to the current actual knowledge of the Dechert LLP attorneys who have rendered legal services to
the Company in connection with the transactions contemplated by the Transaction Documents. 
  
 Based upon the foregoing and subject to the further limitations, qualifications and exceptions set forth below, we are of the opinion that: 
  
 1. The Company is a corporation existing and in good standing under the laws of the State of Delaware. [Relying solely on the Good Standing
Certificate from the State of New Jersey, the Company is qualified to do business as a foreign corporation and is in good standing in the State of New Jersey.] 

 2. The Company has the corporate power to execute and deliver, and perform its obligations under, each of the Transaction
Documents and the Warrant. The Company has the corporate power to conduct its business as now conducted. 
  
 3. The execution and delivery of the Transaction Documents and the Warrant by the Company, the performance of the obligations of the Company thereunder and the consummation by it of the transactions contemplated
therein have been duly authorized and approved by the Company’s Board of Directors and no further consent, approval or authorization of the Company, its Board of Directors or its stockholders is required. 
  
 4. The Transaction Documents and the Warrant have been duly executed and delivered by the
Company. The Transaction Documents and the Warrant are the valid and binding obligations of the Company, enforceable against the Company in accordance with their terms except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, fraudulent transfer, moratorium, or similar laws relating to, or affecting creditor’s rights and remedies, or general principles of equity and public policy, including without limitation, concepts of materiality,
reasonableness, good faith and fair dealing, regardless of whether considered in a proceeding in equity or at law. 
  
 5. The execution, delivery and performance by the Company of the Transaction Documents and the Warrant and the consummation by the Company of the transactions
contemplated thereby including the offering, sale and issuance of the Purchase Shares, the Warrant and the Warrant Shares in accordance with the terms and conditions of the Purchase Agreement and the Warrant, do not: (i) conflict with, constitute a
breach of or default (or an event which, with the giving of notice or lapse of time or both, constitutes or could constitute a breach or a default), under the Certificate of Incorporation, the bylaws of the Company or any contract filed by the
Company pursuant to Item 601(b)(10) of Regulation S-K, as an exhibit to the Annual Report on Form 10-K filed on March 31, 2005 (“Material Contracts”) or (ii) violate any order, writ, injunction or decree applicable to the Company with
respect to which this firm has been engaged by the Company to give substantive attention. 
  
 6. The issuance and sale of the (i) 2,123,142 Purchase Shares pursuant to the terms and conditions of the Purchase Agreement, and (ii) the 1,061,571 shares of Common Stock issuable upon exercise of the Warrant
pursuant to the terms and conditions of the Warrant have been duly authorized by the Company’s Board of Directors. The Board of Directors has duly adopted resolutions reserving for the issuance of 2,123,142 shares of Common Stock for issuance
as Purchase Shares under the Purchase Agreement. When delivered against payment in full as provided in the Purchase Agreement, the Purchase Shares will be validly issued, fully paid and non-assessable, to our knowledge, free of (i) all taxes, liens,
charges and restrictions imposed by the Certificate of Incorporation, the bylaws or under the General Corporation Law of the State of Delaware and (ii) rights of first refusal and preemptive rights imposed by the Certificate of Incorporation, the
bylaws or any Material Contract. The Board of Directors has duly adopted resolutions reserving 1,061,571 shares of Common Stock as Warrant Shares under the Purchase Agreement. When delivered upon exercise and against payment in full as provided in
the Warrant, the Warrant Shares will be validly issued, fully paid and non-assessable, and, to our knowledge, free of (i) all taxes, liens, charges and restrictions imposed by the Certificate of Incorporation, the bylaws or under the General
Corporation Law of the State of Delaware and (ii) rights of first refusal and preemptive rights imposed by the Certificate of Incorporation, the bylaws or any Material Contract. 

 7. To our knowledge, the execution and delivery of the Registration Rights Agreement do not, and the performance by the
Company of its obligations thereunder shall not, give rise to any rights of any other person for the registration by the Company under the Securities Act of 1933, as amended (the “1933 Act”) of any shares of Common Stock or other
securities of the Company under the Certificate of Incorporation, the bylaws or any Material Contract. 
  
 8. Assuming the accuracy of your representations and warranties and your compliance with the covenants made by you, in the Transaction Documents, the offering, sale and issuance of the Purchase Shares and the Warrant
to you pursuant to the Transaction Documents are exempt from registration under the 1933 Act. 
  
 9. Other than that which has been obtained and completed prior to the date hereof, and except for the registration of the shares of Common Stock for resale under the 1933 Act, and the filing of documents under the
Securities Act of 1934 (the “1934 Act”), no authorization, approval, consent, filing or other order of any federal or state governmental body, regulatory agency, or stock exchange or market, or any court, or, to our knowledge, to any third
party to any Material Contract, is required to be obtained by the Company to enter into and perform its obligations under the Transaction Documents and the Warrant or for the Company to issue and sell the Purchase Shares and the Warrant as
contemplated by the Transaction Documents or for the Company to issue and sell the Warrant Shares as contemplated by the Warrant.. 
  
 10. The Company has a class of equity securities registered pursuant to Section 12(g) of the 1934 Act. To our knowledge, since January 1, 2004, the Company has been in
compliance with the reporting requirements of the 1934 Act applicable to it, except as disclosed on Schedule 3(f) in the Purchase Agreement. To our knowledge, other than as disclosed on Schedule 3(f) in the Purchase Agreement, since January 1, 2004,
the Company has not received any written notice from the Principal Market stating that the Company has not been in compliance with any of the rules and regulations (including the requirements for continued listing) of the Principal Market.

  
 11. To our knowledge, except as disclosed on Schedule 3(h) in the Purchase
Agreement, there is no action, suit, proceeding, inquiry or investigation before or by any court, public board or body, any governmental agency, any stock exchange or market, or self-regulatory organization, which has been threatened in writing or
which is currently pending against the Company, any of its subsidiaries, any officers or directors of the Company or any of its subsidiaries or any of the properties of the Company. 
  
 Notwithstanding anything to the contrary, we express no opinion with respect to the legality, validity, binding nature or enforceability,
of: (i) provisions in the Transaction Documents or the Warrant that provide for specific performance or other equitable remedies for noncompliance with any of the provisions contained in the Transaction Documents or the Warrant; (ii) provisions in
the Transaction Documents or the Warrant relating to confidentiality; (iii) provisions in the Transaction Documents or the Warrant related to reimbursement, contribution or indemnification in circumstances in which the person seeking reimbursement,
contribution or indemnification has breached its duties under the applicable Transaction Documents or the Warrant, or otherwise, or itself has been negligent or acted in violation of public policy; or (iv) provisions in the Transaction Documents or
the Warrant related to waivers of rights or defenses. We express no opinion with respect to the application or effect of any laws in respect of state securities laws, or Blue Sky laws, or similar matters relating to the Purchase Shares, the Warrant
or Warrant Shares or to the sale or issuance thereof. 
  
 Whenever our opinion
refers to the Material Contracts, we are referring to the form of the Material Contracts as filed on the website of the SEC. 

 We have not been requested to, and do not, render any opinion on any other matters except as expressly set forth herein,
nor do we express any opinion as to any laws other than those of the United States of America and, to the extent relevant, the General Corporation Law of the State of Delaware, excluding principles of conflict of laws. With your permission, and for
purposes of the opinions expressed in paragraphs 4 and 9 above, we have assumed that the laws of the State of Illinois are identical to those of the State of New Jersey. 
  
 This opinion speaks only as of the date hereof. We assume no obligation to advise you (or any third party) of any changes in the law,
documentation or facts that may occur after the date of this opinion. Our opinions expressed herein are solely for your benefit and, without our express written consent, neither our opinions nor this opinion letter may be assigned to or relied upon
by any other person. 
  
 Very truly yours,

 COMMON STOCK PURCHASE WARRANT #F 101

  

			
	1,061,571 SHARES	 	ORIGINAL ISSUE DATE: APRIL 7, 2005

  
 This Warrant is issued
in connection with and pursuant to that certain Common Stock Purchase Agreement (the “Purchase Agreement”) dated as of April 7, 2005, by and between UNIGENE LABORATORIES, INC., a Delaware corporation (the
“Company”) and FUSION CAPITAL FUND II, LLC (the “Buyer”). 
  
 FOR VALUE RECEIVED, the Buyer, the registered holder hereof, or its permitted assigns (the “Holder”), is entitled to purchase from
the Company, during the period specified in this Warrant, 1,061,571 fully paid and non-assessable shares (subject to adjustment as hereinafter provided) of Common Stock (the “Warrant Shares”), of the Company at the purchase price
per share provided in Section 1.2 of this Warrant (the “Warrant Exercise Price”), all subject to the terms and conditions set forth in this Warrant. All terms not otherwise defined herein shall have the meaning ascribed to them in
the Purchase Agreement. 
  
 Section 1. Period for Exercise and Exercise Price.

  
 1.1 Period for Exercise. The right to purchase
shares of Warrant Shares represented by this Warrant shall be immediately exercisable, and shall expire at 5:00 p.m., Chicago local time, April 7, 2010 (the “Expiration Date”). From and after the Expiration Date this Warrant shall
be null and void and of no further force or effect whatsoever. 
  
 1.2 Warrant Exercise Price. The Warrant Exercise Price per share of Warrant Shares shall be $1.77 per share (subject to adjustment as hereinafter provided). 

 Section 2. Exercise of Warrant. 
  
 2.1 Manner of Exercise. The Holder may exercise this Warrant, in whole or in part, immediately, but not after the
Expiration Date, during normal business hours on any Trading Day by surrendering this Warrant to the Company at the principal office of the Company, accompanied by a Warrant Exercise Form in substantially the form annexed hereto duly executed by the
Buyer and by payment of the Warrant Exercise Price for the number of shares of Warrant Shares for which this Warrant is then exercisable, either (i) in immediately available funds, (ii) by delivery of an instrument evidencing indebtedness owing by
the Company to the Holder in the appropriate amount, (iii) by authorizing the Company to retain shares of Common Stock which would otherwise be issuable upon exercise of this Warrant (in accordance with Section 2.4 hereof) or (iv) in a combination
of (i), (ii) or (iii) above, provided, however, that in no event shall the Holder be entitled to exercise this Warrant for a number of Warrant Shares in excess of that number of Warrant Shares which, upon giving effect to such exercise, would cause
the aggregate number of shares of Common Stock beneficially owned by the Holder to exceed 9.9% of the outstanding shares of the Common Stock following such exercise. For purposes of the foregoing proviso, the aggregate number of shares of Common
Stock beneficially owned by the Holder shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which determination of such proviso is being made, but shall exclude the shares of Common Stock which
would be issuable upon (i) exercise of the remaining, unexercised Warrants beneficially owned by the Holder and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially owned by the
Holder subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended. The Holder may waive the foregoing limitation by written notice to the Company upon not less than 61 days prior written notice (with such waiver taking effect only upon the expiration of such
61 day notice period). 
  
 2.2 When Exercise Effective.
Each exercise of this Warrant shall be deemed to have been effected on the day on which all requirements of Section 2.1 shall have been met with respect to such exercise. At such time the person in whose name any certificate for shares of Warrant
Shares shall be issuable upon such exercise shall be deemed for all corporate purposes to have become the Holder of record of such shares, regardless of the actual delivery of certificates evidencing such shares. 
  
 2.3 Delivery of Stock Certificates. As soon as practicable after each
exercise of this Warrant, and in any event no later than 3 days after such exercise, the Company at its expense will issue Warrant Shares via credit to the Buyer’s account with DTC for the number of Warrant Shares to which such Buyer is
entitled upon such Buyer’s submission of the applicable Warrant Exercise Form or, if the Transfer Agent is not participating in The DTC Fast Automated Securities Transfer Program and DWAC system, issue and surrender to the address as specified
in the Warrant Exercise Form, a certificate, registered in the name of the Buyer or its designee, for the number of shares of Common Stock to which the Buyer shall be entitled to upon such exercise. 

 2.4 Cashless Exercise. The Holder may, by providing notice thereof to the Company along with the
Warrant Exercise Form, elect to exercise the Warrant for a number of Warrant Shares determined in accordance with the following formula: 
  
  

					
	 X
	 	=	 	Y(A-B)
	 	 	 	 	    A

  
 Where: 
  
 X = The number of Warrant Shares to be issued to the Holder. 
  
 Y = The number of Warrant Shares purchasable under this Warrant (at the date
of such exercise). 
  
 A = The fair market value of one share of
Common Stock (or other security for which the Warrant is then exercisable at the date of such exercise). 
  
 B = Exercise Price (as adjusted to the date of such exercise). 
  
 For purposes of this Section 2.4, the “fair market value” per share shall be the closing sale price of the Common Stock for the one Trading Day immediately
prior to the notice of exercise of the Warrant. 
  
 Section 3.
Adjustment of Purchase Price and Number of Shares. The Warrant Exercise Price and the kind of securities issuable upon exercise of the Warrant shall be adjusted from time to time as follows: 
  
 3.1 Subdivision or Combination of Shares (Stock Splits). If the
Company at any time effects a subdivision or combination of the outstanding Common Stock (through a stock split or otherwise), the number of shares of Warrant Shares shall be increased, in the case of a subdivision, or the number of shares of
Warrant Shares shall be decreased, in the case of a combination, in the same proportions as the Common Stock is subdivided or combined, in each case effective automatically upon, and simultaneously with, the effectiveness of the subdivision or
combination which gives rise to the adjustment. 
  
 3.2 Stock
Dividends. If the Company at any time pays a dividend, or makes any other distribution, to holders of Common Stock payable in shares of Common Stock, or fixes a record date for the determination of holders of Common Stock entitled to receive a
dividend or other distribution payable in shares of Common Stock, then the number of shares of Warrant Shares in effect immediately prior to such action shall be proportionately increased so that the Holder hereof may receive upon exercise of the
Warrant the aggregate number of shares of Common Stock which he or it would have owned immediately following such action if the Warrant had been exercised immediately prior to such action. The adjustment shall become effective immediately as of the
date the Company shall take a record of the holders of its Common Stock for the purpose of receiving such dividend or distribution (or if no such record is taken, as of the effectiveness of such dividend or distribution). 
  
 3.3 Reclassification, Consolidation or Merger. If at any time,
as a result of: 
  
 (a) a capital reorganization or
reclassification (other than a subdivision, combination or dividend provided for elsewhere in this Section 3), or 

 (b) a merger or consolidation of the Company with another corporation (whether or not the Company is the
surviving corporation), 
  
 the Common Stock issuable upon exercise of the
Warrants shall be changed into or exchanged for the same or a different number of shares of any class or classes of stock of the Company or any other corporation, or other securities convertible into such shares, then, as a part of such
reorganization, reclassification, merger or consolidation, appropriate adjustments shall be made in the terms of the Warrants (or of any securities into which the Warrants are exercised or for which the Warrants are exchanged), so that: 

 

	 	(y)	the Holders of Warrants or of such substitute securities shall thereafter be entitled to receive, upon exercise of the Warrants or of such substitute securities, the kind and amount
of shares of stock, other securities, money and property which such Holders would have received at the time of such capital reorganization, reclassification, merger, or consolidation, if such Holders had exercised their Warrants immediately prior to
such capital reorganization, reclassification, merger, or consolidation, and 

  

	 	(z)	the Warrants or such substitute securities shall thereafter be adjusted on terms as nearly equivalent as may be practicable to the adjustments theretofore provided in this Section
3.3. 

  
 3.4 Other Action Affecting Common
Stock. If at any time the Company takes any action affecting its Common Stock, other than an action described in any of Sections 3.1 - 3.3 which, in the opinion of the Board of Directors of the Company (the “Board”), would have
an adverse effect upon the exercise rights of the Warrants, the Warrant Exercise Price or the kind of securities issuable upon exercise of the Warrants, or both, shall be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances; provided, however, that the purpose of this Section is to prevent the Company from taking any action which has the effect of diluting the number of shares of Warrant Shares issuable upon exercise of
this Warrant. 
  
 3.5 Notice of Adjustment Events. Whenever
the Company contemplates the occurrence of an event which would give rise to adjustments under this Section 3, the Company shall mail to each Warrant Holder, at least 20 days prior to the record date with respect to such event or, if no record date
shall be established, at least 20 days prior to such event, a notice specifying (i) the nature of the contemplated event, and (ii) the date on which any such record is to be taken for the purpose of such event, and (iii) the date on which such event
is expected to become effective, and (iv) the time, if any is to be fixed, when the holders of record of Common Stock (or other securities) shall be entitled to exchange their shares of Common Stock (or other securities) for securities or other
property deliverable in connection with such event. 
  
 3.6
Notice of Adjustments. Whenever the kind or number of securities issuable upon exercise of the Warrants, or both, shall be adjusted pursuant to Section 3, the Company shall deliver a certificate signed by its Chief Executive Officer and by its
Chief Financial Officer, setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated (including a description of the basis on which the Board made any
determination hereunder), and the Warrant Exercise Price and the kind of securities issuable upon exercise of the Warrants after giving effect to such adjustment, and shall cause copies of such certificate to be mailed (by first class mail postage
prepaid) to each Warrant Holder promptly after each adjustment. 

 Section 4. Reservation of Stock, etc. The Company covenants and agrees that it will at all times
have authorized, reserve and keep available, solely for issuance and delivery upon the exercise of this Warrant, the number of shares of Warrant Shares from time to time issuable upon the exercise of this Warrant. The Company further covenants and
agrees that this Warrant is, and any Warrants issued in substitution for or replacement of this Warrant and all Warrant Shares, will upon issuance be duly authorized and validly issued and, in the case of Warrant Shares, upon issuance will be fully
paid and non-assessable and free from all preemptive rights of any stockholder, and from all taxes, liens and charges with respect to the issue thereof (other than transfer taxes) and, if the Common Stock of the Company is then listed on any
national securities exchanges (as defined in the Exchange Act of 1934, as amended (the “Exchange Act”)) or quoted on NASDAQ, shall be, subject to the restrictions set forth in Section 5, duly listed or quoted thereon, as the case
may be. In the event that the number of authorized but unissued shares of such Common Stock shall not be sufficient to effect the exercise of this entire Warrant into Warrant Shares, then in addition to such other remedies as shall be available to
the Holder of this Warrant, the Company shall promptly take such corporate action as may be necessary to increase its authorized but unissued shares of such Common Stock to such number of shares as shall be sufficient for such purpose. 

 
 Section 5. Ownership, Transfer and Substitution of Warrants. 
  
 5.1 Ownership of Warrants. The Company may treat the person in whose
name any Warrant is registered on the register kept at the principal office of the Company as the owner and Holder thereof for all purposes, notwithstanding any notice to the contrary, but in all events recognizing any transfers made in accordance
with the terms of this Warrant. 
  
 5.2 Transfer and Exchange
of Warrants. Upon the surrender of any Warrant, properly endorsed, for registration of transfer or for exchange at the principal office of the Company, the Company at its expense will execute and deliver to the Holder thereof, upon the order of
such Holder, a new Warrant or Warrants of like tenor, in the name of such Holder or as such Holder may direct, for such number of shares with respect to each such Warrant, the aggregate number of shares in any event not to exceed the number of
shares for which the Warrant so surrendered had not been exercised. 
  
 5.3 Registration Rights. The holder of this Warrant is entitled to certain registration rights with respect to the Warrant Shares issuable upon exercise thereof. Said registration rights are set forth in a Registration Rights
Agreement by and between the Buyer and the Company. IF THE REGISTRATION STATEMENT CONTEMPLATED IN THE REGISTRATION RIGHTS AGREEMENT IS NOT EFFECTIVE AT THE TIME OF ANY ISSUANCE AND THE SHARES ARE NOT EXEMPT FROM REGISTRATION UNDER RULE 144, THE
WARRANT SHARES SHALL BE ISSUED IN CERTIFICATED FORM AND SHALL BEAR THE FOLLOWING RESTRICTIVE LEGEND: 
  
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES
LAWS. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR
APPLICABLE STATE SECURITIES LAWS, OR AN OPINION OF HOLDER’S COUNSEL, IN A CUSTOMARY FORM, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR APPLICABLE STATE SECURITIES LAWS OR UNLESS SOLD PURSUANT TO RULE 144 UNDER SAID ACT. 

 5.4 Exemption from Registration. If an opinion of Buyer’s counsel provides that registration
is not required for the proposed exercise or transfer of this Warrant or the proposed transfer of the Warrant Shares and that the proposed exercise or transfer in the absence of registration would require the Company to take any action including
executing and filing forms or other documents with the Securities and Exchange Commission (the “SEC”) or any state securities agency, or delivering to the Holder any form or document in order to establish the right of the Holder to
effectuate the proposed exercise or transfer, the Company agrees promptly, at its expense, to take any such action; and provided, further, that the Company will reimburse the Holder in full for any expenses (including but not limited to the fees and
disbursements of such counsel, but excluding brokers’ commissions) incurred by the Holder or owner of Warrant Shares on his, her or its behalf in connection with such exercise or transfer of the Warrant or transfer of Warrant Shares.

  
 Section 6. No Rights or Liabilities as Shareholder. Nothing contained
in this Warrant shall be construed as conferring upon the Holder hereof any rights as a shareholder of the Company or as imposing any liabilities on such holder to purchase any securities or as a shareholder of the Company, whether such liabilities
are asserted by the Company or by creditors of the Company. 
  
 Section 7. Rule
144 Sales. At the request of any Holder who proposes to sell securities in compliance with Rule 144 of the SEC, the Company will (i) forthwith furnish to such Holder a written statement of compliance with the filing requirements of the SEC as
set forth in Rule 144, as such rules may be amended from time to time and (ii) make available to the public and such Holder such information as will enable the Holder to make sales pursuant to Rule 144. 
  
 Section 8. Miscellaneous. 
  
 8.1 Amendment and Waiver. This Warrant may be amended with, and only
with, the written consent of the Company and the Holder. Any waiver of any term, covenant, agreement or condition contained in this Warrant shall not be deemed a waiver of any other term, covenant, agreement or condition, and any waiver of any
default in any such term, covenant, agreement or condition shall not be deemed a waiver of any later default thereof or of any default of any other term, covenant, agreement or condition. 
  
 8.2 Representations and Warranties to Survive Closing. All representations, warranties and covenants contained herein
shall survive the execution and delivery of this Warrant and the issuance of any Warrant Shares upon the exercise hereof. 

 8.3 Severability. In the event that any court or any governmental authority or agency declares all
or any part of any Section of this Warrant to be unlawful or invalid, such unlawfulness or invalidity shall not serve to invalidate any other Section of this Warrant, and in the event that only a portion of any Section is so declared to be unlawful
or invalid, such unlawfulness or invalidity shall not serve to invalidate the balance of such Section. 
  
 8.4 Binding Effect; No Third Party Beneficiaries. All provisions of this Warrant shall be binding upon and inure to the benefit of the parties and
their respective heirs, legatees, executors, administrators, legal representatives, successors, and permitted transferees and assigns. No person other than the holder of this Warrant and the Company shall have any legal or equitable right, remedy or
claim under or in respect of, this Warrant. 
  
 8.5
Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Warrant must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii)
upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and kept on file by the sending party); or (iii) one Trading Day after deposit with a nationally recognized overnight delivery

 WHEREAS: 
  
 A. The Company has agreed, upon the terms and subject to the conditions of
the Purchase Agreement, to issue to the Buyer 2,123,142 shares (the “Purchase Shares”), of the Company’s common stock, par value $0.01 per share (the “Common Stock”) and (ii) 1,061,571 shares (the

 NOW, THEREFORE, in consideration of the premises and the mutual covenants contained herein and other good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Buyer hereby agree as follows:

 e. “Registration Statement” means the registration statement
of the Company covering the sale of the Registrable Securities. 
  
 2. REGISTRATION. 
  
 a. Mandatory
Registration. The Company shall within fifteen (15) Trading Days from the date hereof file with the SEC the Registration Statement. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such registration
statement or amendment to such registration statement and any related prospectus prior to its filing with the SEC. Investor shall furnish all information reasonably requested by the Company for inclusion therein. The Company shall use its best
efforts to have the Registration Statement or amendment declared effective by the SEC at the earliest possible date. The Company shall use reasonable best efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under
the 1933 Act and available for sales of all of the Registrable Securities at all times until the earlier of (i) the date as of which the Investor may sell all of the Registrable Securities without restriction pursuant to Rule 144(k) promulgated
under the 1933 Act (or successor thereto) or (ii) the date on which the Investor shall have sold all the Registrable Securities (the “Registration Period”). The Registration Statement (including any amendments or supplements thereto
and prospectuses contained therein) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein, in light of the circumstances in which they
were made, not misleading. 
  
 b. Rule 424 Prospectus. The
Company shall, as required by applicable securities regulations, from time to time file with the SEC, pursuant to Rule 424 promulgated under the 1933 Act, the prospectus and prospectus supplements, if any, to be used in connection with sales of the
Registrable Securities under the Registration Statement. The Investor and its counsel shall have a reasonable opportunity to review and comment upon such prospectus prior to its filing with the SEC. The Investor shall use its reasonable best efforts
to comment upon such prospectus within one (1) Trading Day from the date the Investor receives the final version of such prospectus. 
  
 3. RELATED OBLIGATIONS. 
  
 With respect to the Registration Statement and whenever any Registrable Securities are to be registered pursuant to Section 2(b) including on any New
Registration Statement, the Company shall use its reasonable best efforts to effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof and, pursuant thereto, the Company shall have the
following obligations: 
  
 a. The Company shall prepare and file
with the SEC such amendments (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, 
  

 2 

 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. 
  
 c. Upon request of the
Investor, 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 
  

 3 

 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. 
  
 g. The Company
shall (i) cause all the Registrable Securities to be listed on each securities exchange 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. 
  

 4 

 m. The Company shall take all other reasonable actions necessary 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. 
  
 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. 
  
 a. To the fullest extent permitted by law, the Company will, 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) 
  

 5 

 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 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 by the Company of this
Agreement (the matters in the foregoing clauses (i) through (iv) being, collectively, “Violations”). The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any legal
fees or other reasonable expenses 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 superseded prospectus, shall not inure to the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any person controlling such
person) if the untrue statement or omission of material fact contained in the superceded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such revised 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. 
  
 b. In connection with the Registration Statement or any New Registration
Statement, the Investor agrees to 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 about the Investor set forth on Exhibit B attached hereto and furnished to the Company by the Investor expressly for use in connection with such
registration statement; and, subject to Section 6(d), the Investor 
  

 6 

 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. 
  

 7 

 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 securities of the Company to the public without registration (“Rule 144”), the Company agrees, at the Company’s sole expense, 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 report of the Company and such other reports and documents so filed by the 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. 
  
 d. take such additional action as is
requested by the Investor to enable the Investor to sell the Registrable Securities pursuant to Rule 144, including, without limitation, delivering all such legal opinions, consents, certificates, resolutions and instructions to the Company’s
Transfer Agent as may be reasonably requested from time to time by the Investor and otherwise fully cooperate with Investor and Investor’s broker to effect such sale of securities pursuant to Rule 144.

 9. ASSIGNMENT OF REGISTRATION RIGHTS.

controlled by Steven G. Martin or Joshua B. Scheinfeld.

	 Re: UNIGENE LABORATORIES, INC.

  
 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, dated as of
                    , 2005 (the “Purchase Agreement”), entered into by and between the Company and Fusion Capital Fund II,
LLC (the “Buyer”) pursuant to which the Company has agreed to issue to the Buyer 2,123,142 shares (the “Purchase Shares”), of the Company’s Common Stock, par value $0.01 per share (the “Common
Stock”), in accordance with the terms of the Purchase Agreement. In addition, pursuant to the Stock Purchase Agreement, the Company issued to the Buyer a warrant to purchase 1,061,571 shares (the “Warrant Shares”) of
Common Stock. Pursuant to the Purchase Agreement, the Company also has entered into a Registration Rights Agreement, dated as of
                    , 2005, with the Buyer (the “Registration Rights Agreement”) pursuant to which the Company agreed, among
other things, to register the Purchase Shares and the Warrant 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                     , 2005, 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 and the Warrant 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
5:00 P.M. on                     , 200   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 and the Warrant 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 Purchase Shares and the Warrant Shares. 
  

									
	 	  	 	 	 	 	 Very truly yours,

				
	 	  	 	 	 	 	 [Company Counsel]
