INTELLECTUAL PROPERTY

6.1. Ownership and Inventorship of Sole and Joint Improvements .

6.1.1. Ownership . Unigene shall solely own all right, title, and interest in all Unigene Sole Improvements. Novartis and or its Affiliates shall solely own all right, title, and interest in all Novartis Non-Severable Sole Improvements and Novartis Severable Sole Improvements. Each Party shall own an undivided right, title, and interest, as defined under the applicable U.S. law, in any Joint Improvements and Non-Severable Joint Improvements, and whether patentable or not patentable subject to the provisions of this Agreement. Each Party shall reasonably promptly disclose to the other Party all Improvements made by it. Each Party shall notify the other Party if it wishes to file a patent application concerning an Improvement no later than thirty (30) days before the anticipated date of such filing. If an express grant of rights from one Party to the other is required in any country to give full force and effect to this provision, the Parties shall execute any instrument necessary to accomplish the intent of the foregoing grant.

6.1.2. Inventorship . Inventorship and, subject to this Agreement the rights of ownership, of inventions and other intellectual property rights conceived and/or reduced to practice in connection with the development activities hereunder shall be determined in accordance with the laws of the United States. It is understood that, except as otherwise provided herein, neither Party shall have any obligation to account to the other for profits, or to obtain any approval of the other Party to license, assign, mortgage or exploit a Joint Improvement by reason of joint ownership of any such intellectual property, and may otherwise undertake all activities a

- 16 -

sole owner might undertake with respect to such Joint Improvement without the consent and without accounting to the other joint owner, except as otherwise provided in this Agreement or as the Parties may otherwise agree in writing.

6.2. Filing, Prosecution, Maintenance and Enforcement of Patents .

6.2.1. Licensed Technology . If Unigene elects not to prosecute or maintain such patent applications or ensuing patents or claims included in Unigene Patent Rights in any country of the Territory, Unigene shall give Novartis notice thereof within a reasonable period prior to allowing such patent applications or patents or such claims encompassed by such patent applications or patents to lapse or become abandoned or unenforceable, and Novartis shall thereafter have the right, at its sole expense, to prepare, file, prosecute and maintain such patent applications and patents or divisional applications related to such claims encompassed by such patent applications or patents in countries of Novartis’ choice throughout the world. Patents which Novartis has assumed the prosecution and maintenance of shall no longer be included in the Unigene Patent Rights.

6.2.2. Sole Improvements . Each of Unigene and Novartis (“Filing Party”) shall be responsible for the reasonable and diligent filing and prosecution of all patent applications relating to its Sole Improvements under this Agreement, but no party shall have an obligation to file an application relating to such Sole Improvement. Each Filing Party shall bear the cost and responsibility for the filing and prosecution of all such patent applications. The Filing Party shall provide the other Party with (a) a brief summary of the Sole Invention, and (b) the main claim at least thirty (30) days before the patent application is planned to be filed. The other Party may comment and make recommendations about content and filing strategy, which comments the Filing Party shall take under consideration. The Filing Party shall also keep the other Party informed of all material issues relating to the preparation, filing and prosecution of such patent applications. Neither Party shall file any patent application which shall lead to the disclosure of the other Party’s Confidential Information unless the other Party has first agreed in writing to the filing. If Novartis decides not to continue to prosecute or maintain a patent application or patent in a country for Novartis Non-Severable Sole Improvements after such patent or patent application has been published and Unigene wishes to do so, then the Novartis Non-Severable Sole Improvement and resulting patent applications and patents shall be assigned to Unigene and such patent applications and patents shall become part of Unigene Patent Rights and shall no longer be a Novartis Non-Severable Sole Improvement. Prior to publication, Novartis and/or its Affiliates will have no obligation to assign such patents or patent applications to Unigene.

6.2.3. Joint Improvements . In the case of Joint Improvements and Non-Severable Joint Improvements, the Parties shall decide whether or not to secure patent protection and which Party shall bear the primary responsibility for preparing, filing and prosecuting the Patent applications resulting there from. Patent-related expenses for Joint Improvements and Non-Severable Joint Improvements are **. If the Parties cannot agree which Party shall bear the primary responsibility for preparing, filing, and prosecuting Patent Applications resulting from a Joint Invention or a Non-Severable Joint Improvement, then counsel mutually agreeable to the Parties shall prepare, file and prosecute the patent applications and the Parties shall ** related

- 17 -

thereto. Each Party shall promptly render all necessary assistance reasonably requested by the other Party in applying for and prosecuting the patent applications. Neither Party shall file any patent application on Joint Improvements or a Non-Severable Joint Improvement which shall lead to the disclosure of the other Party’s Confidential Information, unless the other Party has first agreed in writing to the filing. If a Party responsible for the prosecution or maintenance of a patent or patent application directed to a Joint Improvement or a Non-Severable Joint Improvement elects not to continue prosecution or maintenance of such patent or patent application, the Party will give the other Party notice of such election within a reasonable period prior to allowing such patent or patent application to lapse or become unenforceable, and the other Party will have the right to continue prosecution or maintenance of such patent or patent application; and if ** decides not to file a patent application for a Non-Severable Joint Improvement, Unigene shall be permitted to do so. If a Party (the “Relinquishing Party”) declines to pay its share of patent-related expenses for any patent application or patent directed to a Joint Improvement or a Non-Severable Joint Improvement, the other Party may assume payment of the Relinquishing Party’s share of the patent-related expenses, and the Relinquishing Party will assign title to such patent application or patent to Party assuming payment.

6.2.4. Enforcement of Unigene Patent Rights . Subject to Section 6.2.5 below, in the event that a Party learns that any Unigene Patent Rights necessary for the manufacture, use and/or sale of API are infringed or misappropriated by a Third Party in any country in the Territory, or is subject to a declaratory judgment action arising from such infringement in such country, such Party shall promptly notify the other Party hereto. Unigene shall have the initial right (but not the obligation) to enforce such Unigene Patent Rights by initiating an appropriate suit or action against such Third Party, or defend any declaratory judgment action with respect thereto, at its expense, and to use Novartis’ name in connection therewith; provided that such use without Novartis’ written consent may only occur where necessary or indispensable for Unigene to bring such suit or action. Novartis shall have the right to join in any suit or action initiated by Unigene within 90 days of the bringing of such suit or action by Unigene. Novartis may retain counsel of its choosing, at Novartis’ sole expense, or Novartis may utilize the counsel selected and directed by Unigene and share equally in the costs associated therewith. In the event that Unigene fails to initiate a suit or action to enforce such Unigene Patent Rights against such a Third Party in any jurisdiction in the Territory within ninety (90) days after notification of such infringement, Novartis may initiate such suit or action in its own name with regard to the applicable Unigene Patent Rights against such infringement, at the expense of Novartis, and to use Unigene’s name in connection therewith; provided that such use without Unigene’s written consent may only occur where necessary or indispensable for Novartis to bring such suit or action. If Novartis initiates such a suit or action, Unigene will have the right to join within ninety (90) days of the bringing of such suit or action by Novartis. Unigene may retain counsel of its choosing, at Unigene’s sole expense, or Unigene may utilize the counsel selected and directed by Novartis and share equally in the costs associated therewith. If only one Party is prosecuting a suit or action, the Party involved in the suit or action (the “Enforcing Party”), shall keep the other Party hereto reasonably informed of the progress of any such action. Unigene and/or Novartis shall recover their respective actual out-of-pocket expenses, or equitable proportions thereof, associated with any litigation or settlement thereof from any recovery made in a suit or action to which they were an active Party. Any excess amount recovered shall be allocated as follows: if

- 18 -

the suit is joined by both Parties, the excess amount recovered is divided equally, and if only one Party brings the suit (the “Litigating Party”) and is not joined by the other Party, then only the Litigating Party shall receive the excess amount recovered.

6.2.5. Enforcement of Joint Improvement Patent Rights . Notwithstanding anything to the contrary in Section 6.2.4 above, in the event that any patent that is jointly owned by Unigene and Novartis under Section 6.1.1 of this Agreement is infringed or misappropriated by a Third Party, Novartis and Unigene shall discuss whether, and, if so, how, to enforce such jointly owned patent or defend such jointly owned patent in an infringement action, declaratory judgment or other proceeding. In the event only one Party wishes to participate in such proceeding, it shall have the right to proceed alone, at its expense, and may retain any recovery; provided, however, that at the request and expense of the participating Party, the other Party agrees to cooperate and join in any proceedings in the event that a Third Party asserts that the coowner of such Joint Improvement patent rights or Non-Severable Joint Improvement patent rights is necessary or indispensable to such proceedings. The participating Party shall keep the other Party hereto reasonably informed of the progress of such proceeding. Damages recovered by a Party or Parties in an action under this Section 6.2.5 are to be allocated according to the scheme set out in Section 6.2.4, above.

6.2.6. Infringement Claims . If the manufacture, use, or sale of API in the Territory pursuant to this Agreement results in any claim, suit or proceeding alleging patent infringement against Unigene or Novartis, or their Affiliates, such Party shall promptly notify the other Party hereto. If Novartis or its Affiliate is not named as a Party in such a claim, suit or proceeding, Novartis or its Affiliate may, at its own expense and through counsel of its own choice, seek leave to intervene in such claim, suit or proceeding. Unigene agrees not to oppose such intervention. If Novartis or its Affiliate, and not Unigene, is named as a Party to such claim, suit or proceeding, Novartis shall have the right to control the defense and settlement of such claim, suit or proceeding, at its own expense, using counsel of its own choice. Unigene, however, at its own expense and through counsel of its own choice, may seek to intervene if the claim, suit or proceeding relates to the commercialization of the API in the Field, and in such event, Novartis and its Affiliates agree not to oppose such intervention. If Novartis or its Affiliate is named as a Party, or if Novartis or its Affiliate is successful in intervening in actions brought against Unigene or its Affiliate, and Unigene shall, at any time, tender its defense to Novartis or its Affiliate, then Novartis shall defend Unigene in such claim, suit or proceeding, at Novartis’ own expense and through counsel of its own choice, and Novartis shall control the defense and settlement of any such claim, suit or proceeding; provided, Novartis shall not enter into any agreement which (i) extends or purports to exercise Novartis’ rights under Unigene’s Licensed Technology beyond the rights granted pursuant to this Agreement, (ii) makes any admission regarding (a) wrongdoing on the part of Unigene, or (b) the invalidity, unenforceability or absence of infringement of any Unigene Patent Rights or patent claiming a Joint Invention, without the prior written consent of Unigene, which consent shall not be unreasonably withheld. The Parties shall cooperate with each other in connection with any such claim, suit or proceeding and shall keep each other reasonably informed of all material developments in connection with any such claim, suit or proceeding.

- 19 -

6.2.7. Litigation Activities Update . The Parties shall keep one another informed of the status of and of their respective activities regarding any litigation or settlement thereof concerning API, provided however that no settlement or consent judgment or other voluntary final disposition of any suit defended or action brought by a Party pursuant to this Article 6 may be entered into without the written consent of the other Party, which consent shall not be unreasonably withheld or delayed.

EXHIBIT A

CLINICAL SUPPLY AGREEMENT

THIS CLINICAL SUPPLY AGREEMENT (this “Agreement”) is entered into as of April 7th, 2004 (the “Effective Date”), by and between Novartis Pharma AG, a Swiss corporation (“Novartis”), and Unigene Laboratories, Inc., a Delaware corporation (“Unigene”) (each a “Party” and collectively, the “Parties”). All terms not otherwise defined herein shall have their respective meaning as set forth in the License Agreement and the Contract Manufacturing Agreement (as defined below).

In connection with that certain License Agreement, dated as of the date hereof, by and between Novartis and Unigene (the “License Agreement”), and that certain Contract Manufacturing Agreement between Sandoz GmbH and Unigene, Unigene hereby agrees to manufacture, sell and deliver to Novartis the quantities of material described in the Task Order attached hereto as Exhibit A (the “Product”), and in conformity with the terms of the Task Order and the Quality Assurance Agreement entered into by Unigene and Novartis as of the date hereof attached hereto as Exhibit B (the Task Order and the Quality Assurance Agreement are referred to collectively herein as the “Quality Requirements”).

Unless sooner terminated pursuant to Paragraph 12, this Agreement shall commence on the date set forth above and shall continue in force until the Termination Date as defined herein. The Termination Date shall be the date on which Novartis accepts the final shipment of Product to be delivered pursuant to Paragraph 3C of this Agreement.

If Unigene receives a complaint under Paragraph 3(A), the following procedures shall apply:

A - 2

In the Task Order, the Parties shall identify individuals who shall serve as the Parties’ representatives as to technical and administrative matters. Except in case of emergency, all communications between Novartis and Unigene shall be made through these representatives. Any written communication required or deemed necessary hereunder shall be deemed to have been properly served or sent if delivered in person, sent by a recognized overnight delivery service, or deposited in the United States mail, postage prepaid, for mailing by registered or certified mail, and addressed to these representatives.

Unigene shall immediately inform Novartis of any occurrence that creates material uncertainty as to Unigene’s ability to comply fully with any aspect of the Task Order. Without limiting Unigene’s obligations pursuant to this Paragraph, the Parties’ technical representatives shall establish a regular schedule of conferences to facilitate such communications.

A - 3

Intellectual property matter shall be governed by Article 6 of the License Agreement.

Confidentiality and the Exchange of Confidential Information shall be governed by Article 8 of the License Agreement.

Except as otherwise permitted by Section 8.3 of the License Agreement, neither Party shall disclose either the fact or terms of this Agreement without the prior written consent of the other Party except as required by law.

Neither Party will use, or authorize others to use, the name, symbols, or marks of the other Party in any advertising or publicity material or make any form of representation or statement with regard to this Agreement or any Task Order issued hereunder which would constitute an express or implied endorsement by the other Party of any commercial product or service without that other Party’s prior written approval.

Unigene will document all aspects of its procedures as described in the Task Order and Quality Assurance Agreement and will deliver to Novartis (or, where applicable, make available to Novartis for inspection during mutually agreeable times during normal business hours) in a timely manner all of the documentation described in the Task Order. In addition, to the extent that such requests do not include Unigene proprietary or trade secret information and do not conflict with other contractual or legal obligations of Unigene, Unigene will cooperate in good faith to provide any additional documentation that Novartis may reasonably require to determine whether to accept or reject the Product. If Unigene declines to provide any additional documentation in its possession and requested by Novartis, then Novartis may, in its sole discretion, reject the Product.

During the term of this Agreement and for three (3) years thereafter (or for such longer period as may be required by law, regulation, or other administrative requirement), Unigene will maintain all books, records and other documents (including but not limited to the documents referred to in Paragraph 8A) relating to the performance of this Agreement or required to be kept by law or permit.

A - 5

Neither Party shall be liable to the other for any failure to deliver or receive Product or for any delay in delivery or receipt of Product when such failure or delay shall be caused (directly or indirectly) by fire; flood; accident; explosion; equipment or machinery breakdown; sabotage; strike or any labor disturbance (regardless of the reasonableness of the demands of labor); civil commotion; riot; invasion; war; act of terrorism; any act, restraint, requisition, regulation or direction of any governmental authority (whether or not valid); shortage of labor, fuel, power or raw materials; inability to obtain supplies; inability to obtain or delays of transportation facilities; any Act of God; or any other event beyond the reasonable control of the Party whose performance is affected (each, an “Event of Force Majeure”). The Party whose performance is so affected shall provide prompt written notice to the other, shall indicate the estimated duration of such Event of Force Majeure, and shall use all commercially reasonable efforts to mitigate the effects of such Event of Force Majeure. If, by reason of any such Event of Force Majeure, Unigene is excused from performance, then, to the extent Product are not delivered to Novartis in the quantities or at the times required hereunder, Novartis may purchase a replacement product from other sources without liability or obligation to Unigene. In the event Novartis purchases a replacement product from another source, then Novartis may, to the full extent of such purchases, reduce its quantity purchase commitment, if any, hereunder. All such quantities of replacement product so purchased by Novartis shall be considered Product purchased from Unigene for purposes of calculating discounts based on volume allowed under this Agreement, if any. During any period of shortage due to any of said Events of Force Majeure, Unigene shall allocate its supply of Product fairly and equitably among its customers, including Novartis. In addition, Novartis may, at its option, extend the Term of this Agreement to permit partial or total delivery of Product not delivered because of any such Event of Force Majeure. If such Event of Force Majeure continues for more than sixty (60) days, Novartis has the option, at any time thereafter during which the Event of Force Majeure is continuing, to terminate this Agreement without liability to Unigene, except to pay for Product already accepted.
