D. The Purchasers entered into the transaction described in the foregoing recital solely as an accommodation to Unigene (and with the full knowledge and consent of Unigene), and as an interim step toward receiving from Unigene certain Senior Secured Convertible Debentures and an amendment and restatement of the Original Agreement in its entirety. E. The Purchasers and Unigene entered into a Securities Issuance Commitment Agreement dated November 17, 1995 (the "Commitment"), which (i) provided for the Purchasers to lend $778,670 to Unigene (the "Initial Interim Loan") and (ii) set forth the parties' mutual intention that Unigene issue to the Purchasers the aforesaid Senior Secured Convertible Debentures in the aggregate principal amount of $3,000,000 to substitute, amend, restate and re-evidence (but not as a novation or refinancing of) the Original Obligations (including the Initial Principal Amount and the Initial Accrued Interest) as well as to evidence the Initial Interim Loan. F. On or about December 21, 1995, the Purchasers loaned an additional $300,000 to Unigene (the "Second Interim Loan"), and the parties desire that Unigene issue and the Purchasers receive additional Senior Secured Convertible Debentures, of the same tenor as, but of different date than, the aforesaid Senior Secured Convertible Debentures, in said $300,000 principal amount to re-evidence and restate the Second Interim Loan. G.

H. Unigene now proposes to issue and sell to Purchasers, and the Purchasers desire to purchase, two 9.5% Senior Secured Convertible Debentures in the principal amounts of $3,000,000 (Debenture A) and $300,000 (Debenture B), respectively, and on the terms and conditions hereinafter set forth -- which modify the terms of the Commitment in certain respects -- the Debentures to bear interest from November 17, 1995 ($3,000,000) and December 21, 1995 ($300,000), respectively, but to otherwise be of like and similar tenor. I. Unigene and the Purchasers agree that, effective as of the date hereof, (i) the Original Agreement, Original Note and any and all other agreements and understandings governing the terms of repayment of or evidencing the Original Obligations, the Initial Interim Loan and the Second Interim Loan shall be hereby amended and restated in their entirety by this Agreement and by the issuance of "Debenture A" and "Debenture B" referred to and defined below. It is the intention of the parties hereto that the execution and delivery of this Agreement and the issuance of such Debentures hereby not effect a novation, payment, discharge or extinguishment of any of the Original Obligations, the Initial Interim Loan or the Second Interim Loan, but merely constitute a restatement and substitution of the terms of their repayment and security. J.

Unigene shall use best efforts to cause Mrs. Jean Levy to execute and deliver certain amended and restated Subordination Agreements on or before the fifth business day after the date hereof, but shall only be deemed in default (as contemplated by the preceding paragraph) if the agreements referred to in (ii) are not delivered by March 31, 1996.

(c) Unigene shall use best efforts to deliver to Purchasers the favorable opinions of counsel to Unigene, in form and substance satisfactory to the Purchasers and substantially similar to those opinions delivered in connection with the Original Documents. Failure to deliver such opinions shall not, however, in the absence of bad faith, constitute a default under this Agreement or under the Debentures. 2.2 Terms of Debentures. Unigene shall issue to the Purchasers two Senior Secured Convertible Debentures having the terms described in this Agreement. Debenture A shall be issued in the principal amount of $3,000,000 -- relating to the amounts due to Purchasers based upon the November 17, 1995 transactions described above ("Debenture A"). Debenture B shall be issued in the principal amount of $300,000 -- relating to the amounts due to Purchasers based upon the December 21, 1995 transaction described above ("Debenture B"). Collectively, Debenture A and Debenture B shall be referred to herein as the "Debentures". 2.2.1 Maturity Date. The Debentures shall all mature on November 15, 1998 (the "Maturity Date"). Debenture A shall bear interest from November 17, 1995 and Debenture B from December 21, 1995. Debenture A shall be dated November 17, 1995 and Debenture B shall be dated December 21, 1995. 2.2.2 Principal and Interest. Interest shall accrue on each Debenture at the rate of nine and one-half percent (9.5%) per annum, from the date of each Debenture (not the date hereof) until all principal and interest due on such Debenture are paid in full. Interest on the Debentures shall be paid in cash semi-annually, on May 15 and November 15 of each year (each an "Interest Payment Date") commencing May 15, 1996. Interest shall be calculated on the basis of a 360-day year of 12 30-day months. Payment of the principal of and interest on the Debentures shall be made by Unigene to the Purchasers by wire transfer of immediately available funds. 2.2.3 Conversion. (a) The Debentures are convertible into Common Stock, at any time and from time to time, through the Maturity Date. The Debentures are initially convertible at a price per share equal to $1.15, subject to the following adjustments (the "Conversion Price"). (b) On April 1, 1996, July 1, 1996, and thereafter annually on July 1 of each subsequent year (each a "Reset Date"), the Conversion Price shall be reset to the lower of (i) the Conversion Price then in effect, or (ii) 85% of the Market Value of the Common Stock. (c) In the event that during the Registration Period (as hereinafter defined) an effective registration statement covering the public resale of the Common Stock issuable upon conversion of the Debentures is not in effect for more than five (non-consecutive or consecutive) months, the Conversion Price then in effect on the Debentures shall be reduced by 5% each. Subsequent 5% Conversion Price reductions shall occur if such registration statement is not in effect as of more than ten, fifteen, twenty, etc. (non-consecutive or consecutive) month-ends during the Registration Period. Once reduced under the preceding sentence, the Conversion Price shall not be adjusted back, regardless of any future effective registration statements. 2.2.4 Anti-Dilution. (a) Effectiveness. The anti-dilution provisions described in this Section 2.2.4 shall be effective with respect to each Debenture from such Debenture's date of issuance until each such Debenture is paid in full, including all principal and interest due thereon, in accordance with the terms thereof. (b) Computation of Adjusted Conversion Price. The Conversion Price of the Debentures shall be adjusted proportionately downward as provided in this Section 2.2.4(b), in the event that Unigene issues, other than pursuant to the exercise or conversion of a Convertible Security (as hereinafter defined), or sells any shares of its Common Stock (including shares held in Unigene's treasury) for a price below the higher of the then-current Conversion Price or the then-current Market Value of the Common Stock. Forthwith upon any such issuance or sale, the Conversion Price shall be reduced to the price calculated by multiplying the Conversion Price by a fraction, the numerator of which shall be the sum of (a) the number of shares of Common Stock outstanding prior to the issuance on a fully-diluted basis, plus (b) the number of shares of Common Stock which the aggregate cash consideration received by the Company for such issuance would have purchased at the higher of the then-current Market Value or the then-current Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately following such issuance on a fully-diluted basis. (c) Options, Rights, Warrants and Convertible and Exchangeable Securities. Except with respect to rights described in Section 2.2.4(i), if Unigene issues or sells options, rights or warrants to subscribe for shares of Common Stock, or issues any securities or instruments convertible into or exchangeable for shares of Common Stock (collectively, the "Convertible Securities"), which Convertible Securities have an exercise, conversion or exchange price (in the case of warrants or options, when added to the amount paid therefor) below the higher of the then-current Conversion Price or the then-current Market Value of the Common Stock, the Conversion Price in effect immediately prior to the issuance of such Convertible Securities shall be reduced to a price determined by making a computation in accordance with the provisions of Section 2.2.4(b) above. The Conversion Price shall be further adjusted in the manner provided for herein, and only downwards, in the event that the conversion, exercise or exchange price of Convertible Securities is reset subsequent to the issuance thereof. For such purposes, all cash consideration received by Unigene upon issuance thereof and which Unigene would be entitled to receive upon exercise, conversion or exchange of such Convertible Securities, shall be deemed to have been received upon issuance of such Convertible Securities, and the maximum number of shares (without giving effect to the anti-dilution provisions of such instruments) issuable upon full exercise thereof shall be deemed outstanding after the issuance of such Convertible Securities for which adjustment has been made hereunder for purposes of the Section 2.2.4(b) calculation. No adjustment shall be made for the issuance of shares upon the exercise, conversion or exchange of any Convertible Security if any adjustment was made with respect to the issuance of such Convertible Security. (d) Subdivisions and Combinations. In the event that Unigene authorizes a stock split of or otherwise subdivides the outstanding shares of Common Stock, the Conversion Price shall forthwith be proportionately decreased by multiplying it by a fraction, the numerator of which shall be one and the denominator of which shall be the number of shares of Common Stock into which each share existing before the subdivision was subdivided. Reverse stock splits and similar combinations of the outstanding shares of Common Stock shall result in an adjustment reciprocal to that which is described above. (e) Reclassifications, Consolidations, Mergers, etc. In case of any reclassification or change of the outstanding shares of Common Stock (other than a change from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination), or in the case of any consolidation of Unigene with, or merger of Unigene into, another corporation (other than a consolidation or merger in which Unigene is the surviving corporation and which does not result in any reclassification or change of the outstanding shares of Common Stock, except a change as a result of a subdivision or combination of such shares or a change in par value, as aforesaid), or in the case of a sale or conveyance to another corporation of the property of Unigene as an entirety or substantially as an entirety, the Purchasers shall have the right to convert the Debentures, as of the date of such reclassification, change, consolidation, merger, sale or conveyance so as to acquire the kind and number of shares of Common Stock and other securities and property receivable upon such reclassification, change, consolidation, merger, sale or conveyance due to the Purchasers or the owners of the shares of Common Stock underlying the Debentures acquired at the conversion price in effect immediately prior to the record date for such reclassification, change, consolidation, merger, sale or conveyance; provided that in the event of a sale or conveyance to another corporation of the property of Unigene as an entirety or substantially as an entirety or in the case of a consolidation of Unigene with or a merger of Unigene into another corporation (hereinafter a "Sale Transaction"), Purchasers may, at their option, require that the Debentures be paid off, within 45 days of the closing of the Sale Transaction, as follows: (i) if the consideration to be paid to the holders of Common Stock under the terms of the Sale Transaction is either cash or readily marketable stock (i.e., stock that is traded on the NASDAQ or on a national securities exchange issued by an issuer with a market capitalization in excess of $100 million and with an average daily trading volume in excess of the number of shares issued in the Sale Transaction), then the Purchasers shall receive such cash or readily marketable stock on the same basis as all other holders of the Common Stock; however, (ii) if, and to the extent that, the consideration to be paid to the holders of Unigene Common Stock under the terms of the Sale Transaction is anything other than as stated in (i), the Purchasers may require that the Debentures not be converted but rather be paid off in cash at $1.25 for every $1.00 then owing on the Debentures (in respect of both principal and accrued interest), such payment to be made within 10 days of the consummation of such Sale Transaction. (f) Dividends and Other Distributions with Respect to Outstanding Securities. In the event that Unigene shall, except as set forth in Section 2.2.4(g) and with Purchasers' consent as required by Section 6.5, at any time prior to the conversion of all of the Debentures declare a dividend (other than a dividend consisting solely of shares of Common Stock or rights to purchase Common Stock) or otherwise distribute without market value consideration paid, to its shareholders any monies, assets, property, rights, evidences of indebtedness, securities (other than shares of Common Stock or rights to purchase Common Stock), whether issued by Unigene or by another Person, or any other thing of value, the Purchasers shall thereafter be entitled, in addition to the shares of Common Stock or other securities receivable upon the conversion thereof, to receive, upon conversion, the same monies, property, assets, rights, evidences of indebtedness, securities or any other thing of value that they would have been entitled to receive at the time of such dividend or distribution. At the time of any such dividend or distribution, Unigene shall make appropriate reserves to ensure the timely performance of the provisions of this Section 2.2.4(f). (g) Subscription Rights for Shares of Common Stock or Other Securities. In the case Unigene or an Affiliate of Unigene shall at any time, without market value consideration paid, distribute to its shareholders any rights to subscribe for shares of Common Stock or any other securities of Unigene or of such Affiliate, the Purchasers shall be entitled, in addition to the shares of Common Stock or other securities receivable upon conversion, to receive such rights at the time such rights are distributed to the other shareholders of Unigene, on the same basis as the Purchasers would have received such rights had the Debentures been converted immediately prior to the record date for such distribution. (h) Consideration; Expenses, etc. For the purposes hereof, the consideration received by Unigene in any transaction shall be deemed to be the gross amount received therefor before deducting underwriters' discounts, legal fees, finders fees and other costs and expenses incurred in connection with such issuance or sale determined as of the date not later than 45 days after the date of the close of the offering with respect to such issuance or sale. (i) Exceptions to Adjustments. Notwithstanding anything to the contrary herein set forth, no adjustment shall be required to be made: (i) upon the issue or exercise of any conversion or exercise option associated with the Debentures or the Purchased Warrants; or (ii) upon the exercise of any option heretofore or hereafter granted to employees, outside directors or consultants to Unigene pursuant to any benefit plan of Unigene; or (iii) upon the issuance or sale of Common Stock or other securities upon the exercise or exchange of any Convertible Securities to subscribe for or purchase Common Stock which were outstanding on the date hereof. 2.2.5 Preemptive Rights. The Purchasers shall have preemptive rights to acquire, on the same terms as any other purchaser in any public or private financing transaction by Unigene of Common Stock or securities (other than upon the exercise, conversion or exchange of outstanding securities) exercisable to purchase or convertible into Unigene Common Stock (or any security with the economic terms of the Common Stock or such securities, whether a "synthetic equity," a "swap" or whatever), up to such amount of such Common Stock or securities as would result in the Purchasers holding the same percentage of the outstanding Common Stock, on a fully diluted basis, as such Purchasers held prior to such issuance, disregarding securities whose exercise or conversion price is $3.75 or more in excess of the average closing bid price for the Common Stock for the thirty trading days prior to such issuance of additional securities by Unigene. Such preemptive rights shall not apply to (i) the contemplated offering by Unigene of its convertible debentures through Swartz Investments, LLC and (ii) other offerings of securities prior to December 31, 1996 which offerings are individually for 50,000 shares of Common Stock or less, and which in the aggregate total 250,000 shares of Common Stock or less. 2.2.6 Registration Rights. Unigene shall file and use commercially reasonable efforts to keep a shelf registration statement effective covering resales of the Common Stock issuable upon conversion of the Debentures for a period (the "Registration Period") commencing no later than June 30, 1996 and ending no later than the earlier of (i) February 28, 1999, and (ii) the date upon which the Purchasers are able to resell all of the Common Stock into which the Debentures are convertible without registration. 2.2.7 Redemption. (a) The Debentures are subject to redemption at the election of Unigene as of the 15th day of each month beginning December 15, 1996, upon not less than thirty (30) days' notice, in a maximum principal amount of up to $495,000 per month, provided that the average closing bid price of the Common Stock on the NASDAQ or a national securities exchange exceeds 200% (the "Redemption Target Percentage") of the Conversion Price for 20 of the 30 trading days preceding the date of notice. Such required Redemption Target Percentage shall be adjusted downward each month by 2.083% such that the required Redemption Target Percentage will be 175% of the Conversion Price after December 15, 1997, as contemplated by the following paragraph. The redemption price shall be equal to 100% of the principal amount redeemed, plus any accrued but unpaid interest to the redemption date. Notwithstanding the foregoing sentence, interest installments whose stated maturity is on or prior to any such redemption date will be payable to the holders of such Debentures as of such redemption date. (b) The Debentures are subject to redemption at the election of Unigene as of the 15th day of each month beginning December 15, 1997 upon not less than thirty (30) days' notice, in a maximum principal amount of up to $1,100,000, provided that the average closing bid price for the Common Stock on the NASDAQ or a national securities exchange exceeds 175% of the Conversion Price for 20 of the 30 trading days preceding the date of notice. The redemption price shall be equal to 100% of the principal amount redeemed plus any accrued but unpaid interest to the redemption date. Notwithstanding the foregoing sentence, interest installments whose stated maturity is on or prior to such redemption date will be payable to the holders of such Debentures as of such redemption date. (c) In the event that either (i) the Common Stock is not listed on NASDAQ or any national securities exchange or (ii) the Common Stock issuable upon conversion of the Debentures is not the subject of an effective registration statement permitting the immediate resale of such Common Stock, Unigene cannot exercise its redemption option. In the event that Unigene is eligible to and does elect to redeem any portion of the Debentures, the Debenture holders shall have the right to convert all or part of the Debentures to Common Stock at any time through the close of business on the redemption date of the Debentures. Upon any conversion of the Debentures, the Debenture holders shall be entitled to receive any interest accrued on such Debentures through the close of business on the conversion date. (d) In the event of redemption of the Debentures in part only, a new Debenture or Debentures for the unredeemed portion will be issued in the name of the holder of the Debenture upon cancellation of the redeemed Debenture. 2.2.8 Security. The amounts due under the Debentures, including all accrued but unpaid interest, shall be secured by certain Collateral as provided in the Security Agreement. 2.2.9 Transfer. (a) Unigene shall cause to be kept at its corporate offices a register (the register maintained in such office and in any other office or agency of Unigene being herein sometimes referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, Unigene shall provide for the registration of the Debentures and of the registration of transfers of the Debentures. Unigene shall act as Security Registrar for the purpose of registering Debentures and transfers of Debentures as herein provided. (b) Upon surrender for registration of transfer of any Debenture at the office of Unigene, Unigene shall execute and make available for delivery, in the name of the designated transferee or transferees, one or more new Debentures of the same series, of any authorized denominations and of a like aggregate principal amount and maturity or expiration date. All Debentures issued upon any registration of transfer or exchange of Debentures shall be the valid obligations of Unigene, evidencing the same obligation, and entitled to the same benefits under this Agreement, as the Debentures surrendered upon such registration of transfer or exchange. (c) Every Debenture presented or surrendered for registration of transfer or for exchange shall (if so required by Unigene) be duly endorsed or be accompanied by a written instrument of transfer in a form satisfactory to the Security Registrar duly executed, by the holder thereof or his attorney duly authorized in writing. (d) Unless otherwise provided in the Debentures to be transferred or exchanged, no service charge shall be made for any registration of transfer or exchange of Debentures. (e) Unigene shall not be required to register the transfer of or exchange any Debenture selected for redemption in whole or in part, except the unredeemed portion of any Debenture being redeemed in part. 2.2.10 Legend. Each Debenture and each certificate for shares of Common Stock issued upon the conversion of the Debentures shall bear a restrictive legend as contemplated by Section 4.3 of this Agreement. 2.2.11 Authentication. The Debentures shall be executed on behalf of Unigene by its Chairman of the Board, its President or one of its Vice Presidents, under its corporate seal reproduced thereon attested by its Secretary or one of its Assistant Secretaries. The Debentures together with any other document executed pursuant to this Agreement are hereinafter referred to collectively as the "Documents." 2.2.12 Limit on Purchasers' Equity Ownership and Number of Shares Issuable upon Conversion of the Debentures. Purchasers may not acquire, pursuant to anti-dilution adjustments or otherwise, in excess of a 19.5% "fully-diluted" equity interest in Unigene's Common Stock, calculated on the basis prescribed by Securities Exchange Act Rel. No. 8325, i.e., including all shares of Common Stock into which the Debentures and the Purchased Warrants are convertible or exercisable (regardless of conversion or exercise price), as the case may be, as outstanding but excluding all shares of Common Stock subject to acquisition upon conversion or exercise of any derivative securities held by any other investors (again, regardless of conversion or exercise price). Consequently, at each time that the number of shares of Common Stock beneficially owned by the Purchasers (i.e., into which the Debentures and the Purchased Warrants are convertible or exercisable) is adjusted upward through the reset of the Conversion Price or the Purchased Warrants' exercise price or otherwise, a sufficient principal amount of the Debentures shall be automatically converted into such principal amount of Non-Convertible Senior Secured Debentures, in each case due on November 15, 1998 (and otherwise upon events of default as specified in the Debentures) and bearing interest at 17% per annum, so that Purchasers' "fully-diluted" equity interest, calculated as set forth above, does not exceed 19.5%. The Non-Convertible Senior Secured Debentures shall be secured pari passu with the Debentures. In addition to the foregoing limitation on Purchasers' aggregate equity interest in Unigene, and, notwithstanding any term or provision of this Agreement or the Debentures to the contrary, in no event may the total number of shares issuable upon conversion of the Debentures, irrespective of which party or parties holds the Debentures at the time of conversion, exceed 19.5% of Unigene's outstanding Common Stock as of the date hereof. 3.

Neither the execution and delivery of this Agreement and the Documents nor the consummation of the transactions contemplated hereby or thereby will (i) breach or violate any of the terms and conditions of the Articles of Incorporation or Bylaws of Unigene, or (ii) breach or violate any judgment, order, injunction, decree or ruling of any court, arbitrator or any governmental authority, domestic or foreign, or any material contract, material agreement or other material instrument to which Unigene is a party or any of its respective properties, rights or assets is subject or which it is bound or with any statute, law, ordinance, rule or regulation of any federal, state, local or foreign governmental authority or regulatory body, the breach or violation of which (A) would have a material adverse effect on Unigene's properties, assets, business, operations, prospects or financial condition or (B) would impair the ability of Unigene to execute, deliver or perform its obligations under this Agreement or any Document, (C) would terminate or result in the cancellation of any payments under any such agreement, contract or instrument or (D) would result in any material damages or result in or, except as contemplated by this Agreement or the Documents, require the creation or imposition of any Encumbrance of any nature upon or with respect to any of its properties or assets. 3.7 Title to; Condition of Assets; Real Property. Except as set forth in Schedule 3.7, all of Unigene's assets, including the Premises (as defined in the Mortgage) and Collateral (as defined in the Security Agreement), are owned free and clear of all material Encumbrances.

The Financial Statements (i) were prepared in accordance with the books of account and records of Unigene, which accurately reflects all assets and transactions of Unigene, and (ii) present fairly Unigene's financial condition as of the dates thereof and its results of operations for the periods then ended in accordance with GAAP, subject, in the case of the interim Financial Statements, to routine, recurring year-end adjustments. As of the date hereof, except as set forth in the Financial Statements, Unigene has no material contingent liabilities, liabilities for taxes, unusual commitments or unrealized or unanticipated losses which are required to be reflected on a balance sheet prepared in accordance with GAAP. Unigene has delivered to the Purchasers its Forms 10-K for the fiscal years ended December 31, 1993 and 1994 and its Forms 10-Q for the first three fiscal quarters of 1995 as filed with the Securities Exchange Commission. Such reports do not contain any untrue statement or omission of any material fact. 3.10 Tax and Other Returns and Reports. (i) All federal, foreign, state, provincial and local tax returns and tax reports (or extensions relating thereto) required to be filed by or on behalf of Unigene or any affiliated, combined or unitary group of which Unigene is or was a member have been filed on a timely basis with the appropriate governmental agencies in all jurisdictions in which such returns and reports are required to be filed and all such returns and reports were true and correct in all material respects when filed; and (ii) all federal, foreign, state, provincial and local income, profits, franchise, sales, use, occupancy, property, severance, excise, withholding, value added and other taxes as shown on such returns (including interest and penalties) due from Unigene either directly, as part of the consolidated tax return of another taxpayer, or otherwise, have been fully and timely paid, or where payment is not required to have been made, Unigene has set up an adequate reserve or accrual for such payment. Unigene knows of no basis for any other tax, assessment or governmental charge that, individually or in the aggregate, could reasonably be expected to have a material adverse effect on Unigene, its operations or prospects. 3.11 Intellectual Property. (a) Schedule 3.11(a) accurately lists all registered United States and Foreign Patents and Trademarks, and all pending United States Patent and Trademark applications that are owned or controlled by Unigene. (b) Schedule 3.11(b) accurately lists all Intellectual Property owned or controlled by others besides Unigene, the use of which is licensed to Unigene. Unigene is not aware of any other Intellectual Property owned or controlled by others besides Unigene that is material to the ability of Unigene to operate its business as it is currently conducted or as currently contemplated. (c) Schedule 3.11(c) accurately lists all Intellectual Property rights licensed or granted by Unigene to third parties. Unigene is the sole and exclusive owner of the entire right, title and interest in and to the Intellectual Property identified on Schedule 3.11(a) and except for such licenses and rights identified on Schedule 3.11(c), Unigene has not granted nor does there exist by implication or operation of law, any license or other right in respect thereof which does or which will, subsequent to the date hereof, permit or enable any Person other than Unigene to use the Intellectual Property and, moreover, except as set forth in Schedule 3.11(c), none of said Intellectual Property is subject to any Encumbrance. As of the date hereof, there is no pending or, to the best knowledge of Unigene, threatened claim against Unigene asserting (A) that Unigene's use of any of said Intellectual Property infringes or violates any rights of third parties, (B) that the past or present conduct of Unigene's business infringes or violates the rights of third parties, (C) that any third parties have any rights to use any of said Intellectual Property or (D) except as set forth in Schedule 3.15, that any third parties have or will have any right which could adversely affect Unigene's ability to use any of the Intellectual Property after the date hereof; and to the best knowledge of Unigene, there is no basis for any claim of the foregoing types. Neither the Intellectual Property nor Unigene's past or present conduct of its business infringes or violates the rights of third parties. During the past five (5) years, Unigene has not given any notice to any third parties asserting infringement by such third parties of any of said Intellectual Property. To the best knowledge of Unigene, there is no material violation by any person of any right of Unigene with respect to the Intellectual Property. Unigene is not aware of any bars or other restrictions with respect to its rights to utilize any of said Intellectual Property, and no bars or other restrictions on Unigene's rights to utilize any of said Intellectual Property will be created by, or will, by reason of any action or inaction by Unigene, before the date hereof, exist after the consummation of the transactions contemplated hereby. Nothing has come to the attention of Unigene which has led Unigene to form the opinion that any of said Intellectual Property is invalid or that its rights in any of said Intellectual Property are unenforceable in any way, with the proviso that pending patent applications are merely requests for patents, and there can be no guarantee that those requests will be granted and that any patents will necessarily be issued based upon said pending applications, and with the further proviso that applications for trademark registrations are merely requests for registration which may or may not ultimately result in registration with the U.S. Patent and Trademark office. The execution and delivery of this Agreement will not affect or impair Unigene's right to continue to use all of said Intellectual Property without the impairment or alteration thereof and without the payment of any license or other fees (other than that the license fees payable under the License Agreements identified in Schedule 3.11(b)). All of the License Agreements identified on Schedule 3.11(b) are valid agreements, enforceable in accordance with their terms, except that such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization, bulk sales or similar laws from time-to-time in effect which affect the enforcement of creditors' rights generally and by legal and equitable limitations on the availability of specific performance and other equitable remedies. There is no pending or, to the best knowledge of Unigene, threatened claim against either Unigene or, to the best knowledge of Unigene, the licensor of any Licensed Intellectual Property asserting that any of the Licensed Intellectual Property infringes or conflicts with the rights of third parties, or that the present or past conduct of Unigene's business infringes or violates the rights of third parties, and to the best knowledge of Unigene, no basis for any such claim exists. 3.12 ERISA. Unigene has complied in all material respects with the requirements of ERISA; no Reportable Event (as defined in ERISA) has occurred and is continuing with respect to any Plan (as defined in ERISA); and it has no unfunded vested liability under any Plan. 3.13 Permits and Licenses. (a) List of Governmental Permits. Set forth on Schedule 3.13(a) is a list and description of all Permits which are issued to, held or used by Unigene, or for which Unigene has applied, and which are material to the operation and development of its business. There are no other Permits which are material to the operation of Unigene's business as now conducted. Except as otherwise indicated, all Permits listed in Schedule 3.13(a) are in good standing, valid and effective in accordance with their respective terms. Unigene owns the Permits, free and clear of all Encumbrances and subject to no Claims. (b) Compliance with Permits. Except as set forth on Schedule 3.13(b), Unigene is in material compliance with all Permits listed on Schedule 3.13(a) and no governmental proceedings or investigations are pending or, to the best knowledge of Unigene, threatened against it relating to noncompliance with such Permits. 3.14 Governmental Authorizations. No consent, approval or authorization of, or registration, filing or declaration with, any governmental authority is required in connection with the execution, delivery or performance by Unigene of this Agreement or any of the Documents other than those required with respect to the registration contemplated in Section 2.2.6 and the security interest filings contemplated in this Agreement and the Documents. 3.15 Litigation and Proceedings. Except as set forth on Schedule 3.15, there are no causes of action or other litigations or arbitrations or regulatory, administrative, zoning or other governmental proceedings or investigations presently pending or, to the best knowledge of Unigene, threatened, before any court, arbitrator, governmental agency or other forum either against Unigene or any of its properties or assets which relate in any way to Unigene or any of its properties or assets. 3.16 FDA Status. The Unigene manufacturing process is undergoing formal validation in order to obtain GMP (Good Manufacturing Practice) status. Unigene has completed testing of the manufacturing equipment and is now performing the various manufacturing process operations. The validation process is essentially complete when three consecutive "conformance batches" (batches in which all of the in-process and final product test specifications have been met and which are performed in compliance with all cGMP requirements) of product have been prepared. Unigene has received no notice, and is not aware of any state of facts that would lead it to believe, that its Boonton, New Jersey facility will not receive FDA validation to allow Unigene to produce its Calcitonin for human use in the United States. Finally, Unigene has been advised verbally by the FDA that only brief clinical programs designed to test safety and bioequivalence should be required for the approval of Unigene's injectable Calcitonin product. Following validation, Unigene intends to file an IND (investigational new drug application) and initiate clinical programs to support such product approval in 1996. 3.17 Environmental Laws. Unigene has received no notice, and is not aware of any state of fact that would lead it to believe that there exists, or has existed at any real property occupied by it, any hazardous material in violation of any environmental law, rule or regulation. 3.18 Judgments, Orders and Consent Decrees. Unigene is not subject to any judgment, order or decree of, or agreement with, any court, arbitrator or regulatory authority limiting, restricting or adversely affecting its conduct, financial condition or operating result, and no such judgment, order, decree or agreement is pending. 3.19 No Omissions. No representation, warranty, covenant or agreement of Unigene in this Agreement, any schedule or exhibit attached hereto, or any Document contains nor shall contain any untrue statement of material fact nor omits nor shall omit to state any material fact necessary to make the statements contained herein and therein not misleading. 4. Representations and Warranties of the Purchasers. 4.1 Standing and Capacity. (a) Olympus represents and warrants to Unigene that it has all requisite legal and corporate power to execute and deliver this Agreement and the other Documents to which it is a party, to purchase the Debentures, and to perform its obligations under this Agreement and the other Documents to which it is a party. Olympus has the capacity to enter into the transactions contemplated by the Documents; neither the execution, delivery nor performance of this Agreement or the Documents violates any law, rule or regulation, of any jurisdiction, court or administrative judgment, order or decree or any agreement applicable to or binding upon Olympus.

Each Purchaser represents and warrants to Unigene that all action necessary for the purchase of the Debentures and the performance of its obligations under this Agreement and the other Documents to which it is a party has been duly taken. The Agreement is valid and binding upon it and enforceable in accordance with its terms except as such enforceability may be limited by applicable bankruptcy, insolvency, moratorium, reorganization, bulk sales, or similar laws from time to time in effect which affect the enforcement of creditors' rights generally and by legal and equitable limitations on the availability of specific performance and other equitable remedies against it, public policy. 4.3 Investment Representation. Each Purchaser represents and warrants to Unigene that (i) it is acquiring the Debentures for investment, for its own account as principal and not with the current view to distribution or trade thereof, (ii) it is an "accredited investor" as defined in Rule 501(a) and (iii) the questionnaire executed and delivered by it to Unigene in connection with the transactions contemplated hereby is true and accurate in all material respects and does not omit any material information required to be stated therein or necessary to make the Statements made therein not misleading. The Debentures and shares issued upon conversion of the Debentures shall bear restrictive legends that are customary for securities that are issued without registration under the Securities Act in reliance on a "private placement exemption." 5. Affirmative Covenants of Unigene. Unigene covenants that, until the principal of, and interest on, the Debentures and all other monetary obligations to the Purchasers under the Debentures have been paid in full, it will: 5.1 Corporate Existence.

The Purchasers agree to keep in confidence and not to utilize or disclose any confidential information provided to them, including, without limitation, financial statements or information, business plans, proposed financing or acquisition plans, information concerning Unigene's products, patents, patent applications, trade secrets, secret processes or other proprietary information unless and until such confidential information is publicly disseminated by Unigene. This confidentiality provision shall survive the execution and delivery of this Agreement, but if Unigene defaults on its obligations and the Purchasers take possession of the Collateral, such confidentiality obligation shall terminate to the extent reasonably necessary to enable the Purchasers to sell any of the Collateral. In such event, the Purchasers may disclose or use any confidential information in a manner as it deems necessary (in its sole judgment) to obtain payment of all Obligations. 5.5 Compliance with Laws. Comply with the applicable requirements of all laws and all rules, regulations and orders of any governmental authority, the violation of which might be reasonably expected to have a material adverse effect on its business, operating results, assets or condition (financial or other). 5.6 Reporting Requirements.

Success Fee. During the period commencing on March 6, 1996 and ending on December 31, 1996, Unigene intends to raise additional funds through "Funding Events" -- including, without limitation, the sale of Unigene's convertible debentures pursuant to the Regulation S offering managed by Swartz Investments LLC -- in an amount not less than $9,000,000 (the "Minimum Financing Target"). As of December 31, 1998, Unigene shall become obligated to pay, such payment to be made as provided in the last paragraph of this Section 8, to the Purchasers an amount equal to the sum of (i) 2% of the Enterprise Value of Unigene as of such date plus (ii) (a) the fraction the numerator of which is the shortfall between the Net Proceeds from Funding Events and the Minimum Financing Target and the denominator of which is the Minimum Financing Target multiplied by (b) 18% multiplied by (c) the Enterprise Value of Unigene as of such date.
