(a) ** percent (**%) of annual Net Sales up to ** U.S. dollars (<U.S. $**);

(b) ** percent (**%) of annual Net Sales including and in excess of ** U.S. dollars (³US $**) up to ** U.S. dollars (<U.S. $**);

(c) ** percent (**%) of annual Net Sales including and in excess of ** U.S. dollars (³U.S. $**) up to ** U.S. dollars (<U.S. $**); and

(d) ** percent (**%) of annual Net Sales including and in excess of ** U.S. dollars (³U.S. $**);

provided that, for purposes of this Section, achievement of the Net Sales thresholds set forth shall be determined by adding the total annual Net Sales of all Licensed Products during each calendar year in all countries of the Territory in which there is a Valid Claim of Unigene Formulation Patent Rights claiming the particular Licensed Product at the time such Net Sales of such Licensed Product occur.

By way of example, if the annual Net Sales were ** U.S. dollars (U.S. $**), then the royalties due under this Section would be ** U.S. dollars (U.S. $**), calculated as (U.S. $** x **%) plus (U.S. $** x **%).

3.4.2. Payment of Royalties. Payment of royalties shall be made forty-five (45) days after the end of each Calendar Quarter on all Net Sales in the preceding quarter (“Quarterly Payment”).

In the event that a Net Sales threshold as described in Section 3.4.1 is met during a Calendar Quarter, all subsequent Quarterly Payments in that calendar year shall be made at the higher applicable royalty rate. Included in the Quarterly Payment for the fourth Calendar Quarter of each calendar year, GSK shall include any additional royalties owed for Net Sales in the calendar year to which the last Calendar Quarter relates, based on the annual Net Sales.

3.4.3. Royalty where Substantial Competition of an Equivalent Product Exists. Where substantial competition by an Equivalent Product exists in a country in which a Valid Claim within all Unigene Formulation Patent Rights exists, the applicable royalties set forth in Section 3.4.1 on Net Sales in such country shall be reduced by ** percent (**%) for each Calendar Quarter in which substantial competition exists. By the term “substantial competition” as used in this Section 3.4.3 is meant the situation where an Equivalent Product

- 12 -

3.9.1. Unigene Notification Regarding ** Patent. Notwithstanding Unigene’s obligations under Section 3.8 of this Agreement to reimburse part of certain Third Party payments, Unigene shall have no such obligation to make any such payments for use of technology claimed in the ** Patent in the event that: (i) Unigene notifies GSK in writing that it believes that the method of manufacture of the API and/or the Licensed Product is not within the scope of any claim of the ** Patent; and (ii) GSK does not respond in writing to Unigene within forty-five (45) days of receipt of Unigene’s notice. In the event GSK provides written response to Unigene, GSK will notify Unigene of its election to have an outside patent expert (“Outside Expert”) who is not affiliated with either Party determine whether the method of manufacturing the API and/or the Licensed Product is within one or more claims of the ** Patent, in accordance with Section 3.9.2 below.

3.9.2. Outside Expert Opinion on Scope of ** Patent. In the event that GSK gives notice to Unigene under Section 3.9.1 that GSK elects an Outside Expert determination, the Parties shall promptly select a mutually acceptable objective patent expert to act as Outside Expert and shall supply such Outside Expert with such materials and information as either Party may deem relevant, or as the Outside Expert may request. The Outside Expert will be asked to render a full and well reasoned, written opinion (“Opinion”) that the Outside Expert believes that it is more likely than not that either:

(1) the manufacturing process for the API and/or Licensed Product is within the scope of the ** Patent; or

(2) the method of manufacturing the API and/or Licensed Product is outside the scope of the ** Patent.

The Outside Expert, in rendering this Opinion, shall utilize only the facts and materials provided by the Parties and shall apply the body of law relevant to patent claim interpretation for

- 15 -

infringement purposes (including doctrine of equivalents and file history estoppel analysis), as set forth in Title 35 of the United States Code and related case law. The Opinion shall contain the Outside Expert’s explanation for his conclusions and shall be provided to both parties promptly after completion.

3.9.3. Effect of Opinion. In the event that the Outside Expert determines that the method of manufacturing the API and/or Licensed Product is not within the scope of the ** Patent, then Unigene shall not be required to reimburse GSK with respect to the ** Patent, and GSK shall reimburse Unigene for all deductions from Quarterly Payments related to use of technology claimed in the ** Patent made after the date of notice provided under Section 3.9.1, such reimbursement to be made no later than the next Quarterly Payment after the date of the Opinion set forth in Section 3.9.2. In the event that the Outside Expert determines that the method of manufacturing the API and/or the Licensed Product is within the scope of the ** Patent, then Unigene’s obligation of reimbursement under Section 3.7 with respect to the ** Patent shall continue uninterrupted.

3.9.4. Fees. The fees paid to the Outside Expert shall be borne equally between the Parties.

3.9.5. Finality. The Opinion of the Outside Expert shall be final for the purposes of determining Unigene’s reimbursement obligations under Section 3.7 of this Agreement with respect only to the ** Patent, and shall not be appealable by either Party. However, the procedure set forth in Section 3.9 may be repeated upon the request of either Party in the event that the method of manufacturing the API and/or Licensed Product is substantially changed and/or the ** Patent is reissued subsequent to the rendering of an Opinion by an Outside Expert.

3.12. Manner of Payments. All sums due to Unigene or to ** under this Agreement shall be payable in United States Dollars by bank wire transfer in immediately available funds to such bank account as Unigene shall designate. GSK shall notify Unigene as to the date and amount of any such wire transfer to Unigene at least two (2) business days prior to such transfer. Interest for payments that are not paid within thirty (30) days of the date on which they were due shall accrue at **percent (**%) per month or portion thereof from the date payment was due.

3.13. Tax Withholding. Any tax, duty or other levy paid or required to be withheld by GSK or its sublicensees on account of royalties or other payments payable to Unigene or ** under this Agreement shall be deducted from the amount of royalties or payments otherwise due, provided that GSK shall make such deductions only to the minimum extent required by the relevant jurisdiction. GSK shall secure and send to Unigene and ** proof of any such taxes, duties or other levies withheld and paid by GSK or its sublicensees for the benefit of Unigene and **, and cooperate at Unigene’s reasonable request to ensure that amounts withheld are reduced to the fullest extent permitted by the relevant jurisdiction.

3.14. Financial Records and Audits; Unigene’s Right to Audit. Unigene, at its own cost, through an independent auditor reasonably acceptable to GSK, may inspect and audit the records of GSK pertaining to the sale of Licensed Product and any royalties due to Unigene under Section 3.4. GSK shall provide such auditors with access to the records during reasonable business hours. Such access need not be given to any such set of records more often than once each year or more than three (3) years after the date of any report to be audited, and the auditors shall report to Unigene only the amount of royalty due. Unigene shall provide GSK with written notice of its election to inspect and audit the records related to the royalty due hereunder not less than thirty (30) days prior to the proposed date of review of GSK’s records by Unigene’s auditors. GSK shall maintain sufficient records to permit the inspection and auditing permitted hereunder for three (3) years after the date of each respective reporting period. GSK shall prepare its records and reports according to generally accepted accounting principles of the United States. Should the auditor find any underpayment of royalties by GSK, GSK shall promptly pay Unigene the amount of such underpayment, plus interest at the rate of ** percent (**%) per month or portion thereof on the amount of any underpayment from the date payment was due, and shall reimburse Unigene for the cost of the audit should such underpayment equal or exceed ** percent (**%) of royalties paid during the time period audited.

6.5. Enforcement.

6.5.1. Unigene Patent Rights. Subject to Section 6.5.2 below, in the event that a Party learns that any Unigene Patent Rights necessary for the manufacture, use and/or sale of a Licensed Product are infringed or misappropriated by activities in the Field related to Licensed Product 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. GSK shall have the initial right (but not the obligation) to enforce such Unigene Patent Rights, or defend any declaratory judgment action with respect thereto, at its expense, and to use Unigene’s name in connection therewith; provided that such use without Unigene’s written consent may only occur where required by law for GSK to bring such action. In the event that GSK fails to initiate a suit 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, Unigene may initiate such suit in the name of the Unigene with regard to the applicable Unigene Patent Rights against such infringement, at the expense of Unigene, and to use GSK’s name in connection therewith. The Party involved in any such claim, suit or proceeding (the “Enforcing Party”), shall keep the other Party hereto reasonably informed of the progress of any such claim, suit or proceeding. Unigene and GSK shall recover their respective actual out-of-pocket expenses, or equitable proportions thereof, associated with any litigation or settlement thereof from any recovery made by any Party. Any excess amount shall be distributed between the Enforcing Party and the other party in the ratio equivalent to the profit GSK derives from Licensed Product in the Territory relative to the royalty Unigene derives from Licensed Product in the Territory, with the Enforcing Party receiving the larger proportion of the excess amount, provided that in no event shall a Party receive a proportion of the excess amount less than the proportion of the total out-of-pocket expenses paid by such Party.

6.5.2. Jointly Owned Patents. Notwithstanding Section 6.5.1 above, in the event that any patent that is jointly owned by Unigene and GSK under Section 6.1 of this Agreement is infringed or misappropriated by a Third Party, GSK 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, 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 co-owner of such Joint Invention is necessary or indispensable to such proceedings.

6.6. Infringement Claims. If the manufacture, sale or use of any Licensed Product in the Territory pursuant to this Agreement results in any claim, suit or proceeding alleging patent infringement against Unigene or GSK, such Party shall promptly notify the other Party hereto. If GSK is not named as a Party in such a claim, suit or proceeding, GSK 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 GSK, and not Unigene, is named as a Party

- 23 -

to such claim, suit or proceeding, GSK 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, however Unigene, 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 Licensed Product in the Field, and in such event, GSK agrees not to oppose such intervention. If GSK is named as a Party and Unigene shall, at any time, tender its defense to GSK, then GSK shall defend Unigene in such claim, suit or proceeding, at GSK’s own expense and through counsel of its own choice, and GSK shall control the defense and settlement of any such claim, suit or proceeding; provided, GSK shall not enter into any agreement which (i) extends or purports to exercise GSK’s 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. Nothing in this Section 6.5 shall limit or modify the provisions of Article 9, which may apply to such infringement claims as discussed herein.

6.7. 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 Licensed Product, 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.

6.8. GSK’s Extensions of Unigene Patent Rights, Pipeline Protection and Supplementary Patent Certificates (“SPCs”).

6.8.1. Patent Extensions. GSK shall have the right but not the obligation to seek extensions of the terms of Unigene Patent Rights. At GSK’s request, Unigene shall either authorize GSK to act as Unigene’s agent for the purpose of making any application for any extensions of the term of Unigene Patent Rights and provide reasonable assistance therefor to GSK or shall diligently seek to obtain such extensions, in either event, at GSK’s expense.

6.8.2. SPCs. At GSK’s request and expense, Unigene shall seek to obtain SPCs based on Unigene Patent Rights or authorize GSK to obtain SPCs based on Unigene Patent Rights on Unigene’s behalf. Where GSK holds a relevant Marketing Authorization, GSK shall at its sole discretion provide to Unigene a copy of said Marketing Authorization and any information necessary for the purpose of obtaining an SPC based on a Unigene Patent Right.

6.8.3. Pipeline Protection At GSK’s request and expense, Unigene shall cooperate with GSK to obtain “pipeline” protection for Unigene Patent Rights which may be available under the patent laws of countries in the Territory in which the patent laws thereof are amended to provide improved protection for Licensed Product.

6.9. Unigene’s Additional Patent Protection. Notwithstanding Sections 6.8.1 and 6.8.2, Unigene shall have the right, but not the obligation, to seek extensions of the terms of Unigene Patent Rights and to seek to obtain SPCs based on Unigene Patent Rights at its own expense. At Unigene’s request, GSK shall provide to Unigene a copy of any requested NDA or MAA where GSK holds such NDA or MAA, and any information necessary for the purpose of seeking such extensions of Unigene Patent Rights and obtaining SPCs.

6.10. Trademarks. GSK, its Affiliates, and its sublicensees shall have the right to market Licensed Product under their own labels, tradenames, and trademark(s) (collectively, the “GSK Marks”) and GSK shall solely own such trademarks, labels and tradenames. GSK shall be responsible for the selection of all GSK Marks that it employs in connection with Licensed Product in the Territory and shall own and control such GSK Marks and retain ownership upon termination or expiration of this Agreement, except as provided in Section 10.5.6. GSK shall be responsible for filing, registering and maintaining all GSK Marks throughout the Territory.

INDEMNIFICATION

9.1. Indemnification of GSK. Unigene shall indemnify and hold harmless GSK and its Affiliates, and their respective directors, officers, employees, agents and counsel, and the successors and assigns of the foregoing (the “GSK Indemnitees”), from and against any and all liabilities, damages, losses, costs or expenses (including reasonable attorneys’ and professional fees and other expenses of litigation and/or arbitration) resulting from a claim, suit or proceeding brought by a Third Party against a GSK Indemnitee, arising from or occurring as a result of: (i) the failure of API manufactured and supplied by Unigene to meet on delivery the Specifications agreed by the Parties, or (ii) the failure by Unigene to obtain or maintain rights under Unigene Patent Rights sufficient to grant GSK an exclusive license in accordance with Article 2 of this Agreement; or (iii) Unigene’s material breach of any representation or warranty

- 29 -

set forth in Section 7.1.1, except, in each case, to the extent caused by the negligence or willful misconduct of GSK or to the extent that GSK is obligated to indemnify Unigene under Section 9.2 below. It is understood that the foregoing indemnity under Section 9.1 shall not include any lost profits or consequential damages.

9.2. Indemnification of Unigene. GSK and its Affiliates and sublicensees shall indemnify and hold harmless Unigene and its Affiliates and their respective directors, officers, employees, agents and counsel and the successors and assigns of the foregoing (the “Unigene Indemnitees”), from and against any and all liabilities, damages, costs or expenses (including reasonable attorneys’ and professional fees and other expenses of litigation and/or arbitration) resulting from a claim, suit or proceeding brought by a Third Party against a Unigene Indemnitee, arising from or occurring as a result of: (i) the conduct of clinical trials and development activities hereunder by GSK or its Affiliates or sublicensees, or (ii) the development, manufacture, marketing and/or commercialization of any Licensed Product by GSK or its Affiliates or sublicensees (including without limitation, Licensed Product liability claims); or (iii) GSK’s material breach of any representation or warranty set forth in Section 7.1.2 except, in each case, to the extent caused by the negligence or willful misconduct of Unigene or to the extent that Unigene is obligated to indemnify GSK under Section 9.1.

A Party (the “Indemnitee”) that intends to claim indemnification under this Article 9 shall promptly notify the other Party (the “Indemnitor”) in writing of any loss, claim, damage, liability or action in respect of which the Indemnitee or any of its Affiliates, sublicensees or their directors, officers, employees, agents or counsel intend to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the Parties. The indemnity agreement in this Article 9 shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is made without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Article 9. At the Indemnitor’s request, the Indemnitee under this Article 9, and its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation and defense of any action, claim or liability covered by this indemnification and provide full information with respect thereto.

TERM AND TERMINATION

10.1. Term and Early Termination by GSK. This Agreement shall be effective as of the Effective Date. If Unigene fails to ** a copy of the fully executed UT License Agreement to GSK by June 30, 2002, GSK, in its sole discretion, may, by written notice to Unigene, immediately terminate this Agreement. After the Effective Date, unless this Agreement is

- 30 -

otherwise terminated earlier pursuant to this Section 10.1 or pursuant to the other provisions of this Article 10, this Agreement shall continue in full force and effect on a Licensed Product-by-Licensed Product and country-by-country basis until the date GSK and its Affiliates and sublicensees have no remaining royalty obligations in such country in accordance with Sections 10.1.1, 10.1.2 and 10.1.3.

10.1.1. Royalty Expiration where Valid Claim Exists. Royalty obligations under Section 3.4 in each country of the Territory shall expire upon the expiration or invalidation of the last remaining issued Unigene Formulation Patent Right in such country, which claims the Licensed Product sold. Expiration of GSK’s royalty obligations under Section 3.4 for a particular Licensed Product under this provision shall not preclude GSK from continuing to market such Licensed Product and to use Unigene Patent Rights and Unigene Know-How in such country without further royalty payments or any other remuneration to Unigene, except to the extent that Section 3.5 is still applicable to the Net Sales of the particular Licensed Product in the particular country.

10.1.2. Royalty Expiration where No Valid Claim Exists. Royalty obligations under Section 3.5 in each country shall expire upon the ** (**) anniversary of the date of First Commercial Sale in such country. Expiration of GSK’s royalty obligations for a particular Licensed Product under this provision shall not preclude GSK from continuing to market such Licensed Product and to use Unigene Know-How in such country without further royalty payments or any other remuneration to Unigene.

10.1.3. Royalty Expiration. Upon expiration of GSK’s royalty obligations under Sections 10.1.1 and 10.1.2, GSK shall have a fully paid up, royalty free, perpetual, irrevocable, non-exclusive, world wide license, with the right to sublicense subject to this Section 10.1.3, and GSK shall be free to make, have made, use and sell Licensed Product and to use Unigene Know-How in the Territory, without further royalty payments or any other remuneration to Unigene. GSK’s right to sublicense as to making and having made API shall be subject to Section 2.1 for any new subcontracts to manufacture API or PTH entered into by GSK after expiration of GSK’s royalty obligations under Sections 10.1.1 and 10.1.2., but only with respect to a Third Party with which GSK had not subcontracted prior to the expiration of its royalty obligations, which Third Party shall continue to be subject to confidentiality obligations no less stringent than those set forth in Article 8.

10.2. Termination for Material Breach. Either Party may terminate this Agreement in the event the other Party has materially breached or defaulted in the performance of any of its obligations hereunder, and if such default is not corrected within sixty (60) days after receiving written notice from the other Party with respect to such default, such other Party shall have the right to terminate this Agreement by giving written notice to the Party in default, provided the notice of termination is given within one (1) year of when the Party giving notice knew or should have known of the default and prior to correction of the default; provided that the time period for providing such notice of termination shall be extended for so long as the Parties are engaged in good faith negotiations to resolve the situation. Notwithstanding the above, in the case of a

- 31 -

failure of GSK to pay any royalty due hereunder, the period for cure of any such failure to pay following notice from Unigene thereof shall be thirty (30) days and, unless payment is made by GSK within such period or unless GSK has notified Unigene that a good faith dispute exists regarding GSK’s failure to pay, the termination shall become effective at the end of such thirty (30) day period.

10.3. Termination for Insolvency; Retention of License. If voluntary or involuntary proceedings by or against a Party are instituted in bankruptcy under any insolvency law, or a receiver or custodian is appointed for such Party, or proceedings are instituted by or against such Party for corporate reorganization or the dissolution of such Party, which proceedings, if involuntary, shall not have been dismissed within sixty (60) days after the date of filing, or if such Party makes an assignment for the benefit of creditors, or substantially all of the assets of such Party are seized or attached and not released within sixty (60) days thereafter, the other Party may immediately terminate this Agreement effective upon notice of such termination. Notwithstanding the bankruptcy of a Party, or the impairment of performance by a Party of its obligations under this Agreement as a result of bankruptcy or insolvency of such Party, and subject to such Party’s rights to terminate this Agreement for reasons other than bankruptcy or insolvency as expressly provided in this Agreement, the other Party shall be entitled to retain the licenses under the terms and conditions granted herein.

10.4. Termination by GSK. At any time after one (1) year after the Effective Date, GSK may terminate this Agreement in its sole discretion on a country-by-country basis, or in its entirety, by giving Unigene at least ninety (90) days written notice (with such written notice to include a reasonably detailed explanation of the reasons for the termination, including the applicable provision of this Section 10.4 and the supporting evidence therefore) thereof at any time for any of the reasons set forth below based on a reasonable determination by GSK, using the same standards GSK would use in assessing whether or not to continue development or commercialization of a product of its own making in its own portfolio, that:

(i) the Licensed Product has:

(1) safety concerns which do not justify continued development or commercialization, would significantly disadvantage the Licensed Product with respect to other compounds or products and/or would significantly reduce the value of the opportunity, all in GSK’s reasonable business determination; or

(2) efficacy concerns which do not justify continued development or commercialization, or would significantly disadvantage the Licensed Product with respect to other compounds or products and/or would significantly reduce the value of the opportunity, all in GSK’s reasonable business determination; or

(3) substantial difficulty in meeting developmental timelines; or

(4) substantial increases in development costs from current projections;

- 32 -

(ii) the cost of goods for commercial supply of Licensed Product would significantly reduce the value of the opportunity;

(iii) changes to the osteoporosis market and/or the competitive environment reduce the sales forecast below a commercially viable threshold normally applied by GSK within its own portfolio;

(iv) government, regulatory or another recognized institution imposes a new law or requirement, or establishes guidelines or a pattern of practice, which means:

(1) the continued development or commercialization of the Licensed Product violates such a law or requirement, or

(2) the value of the opportunity is significantly reduced, or

(3) the pricing and/or reimbursement environment has changed in such a way as to significantly reduce the projected value of the opportunity, or

(4) a condition in (i) or (iii) above becomes applicable.

10.5. General Effect of Termination.

10.5.1. Accrued Obligations. Termination of this Agreement for any reason shall not release any Party hereto from any liability which, at the time of such termination, has already accrued to the other Party or which is attributable to a period prior to such termination, nor preclude either Party from pursuing any rights and remedies it may have hereunder or at law or in equity which accrued or are based upon any event occurring prior to such termination.

10.5.2. Return of Materials. Upon any termination of this Agreement, GSK and Unigene shall promptly return to the other Party all materials and tangible Confidential Information received from the other Party (except one copy of which may be retained by legal counsel for archival purposes).

10.5.3. Stock on Hand. In the event this Agreement is terminated for any reason after commencement of commercial sales of Licensed Product by GSK and/or its Affiliates and sublicensees, GSK and its Affiliates and sublicensees shall have the right to sell (as to Licensed Product only) or otherwise dispose of the stock of any API, PTH and Licensed Products then on hand for a period of six (6) months after the date of termination, subject to Article 3 and the other applicable terms of this Agreement, including, but not limited to, royalty obligations.

10.5.4. Licenses. In the event of termination by GSK pursuant to Section 10.1, 10.3 or 10.4 or termination by Unigene under Section 10.2 due to GSK’s material breach, the licenses granted to GSK under Section 2.1 shall terminate. In the event of termination by GSK pursuant to Section 10.2 due to Unigene’s material breach, all licenses granted by Unigene to GSK under Section 2.1 shall survive and continue in full force, and GSK shall be obligated to

- 33 -

continue to make payments under Article 3 to Unigene to the extent GSK continues to develop, use, market, sell or import PTH or Licensed Product in the Field in the Territory. In the event of termination by GSK under Section 10.4, or by Unigene under Section 10.2 or Section 10.4, the licenses granted by GSK to Unigene under Section 2.3 shall take effect.

10.5.5. Regulatory Filings/Approvals. In the event of termination by GSK pursuant to Section 10.4, or by Unigene pursuant to Section 10.2 or 10.3, GSK shall ensure that all regulatory filings and approvals relating to the Licensed Product are assigned to Unigene (to the extent legally permissible in the relevant country) within a reasonable time after any termination of GSK’s rights under this Agreement. Any costs incurred by GSK for such assignment or transfer shall be at GSK’s expense. In the event that no such assignment and/or transfer pursuant to this Section may legally be made, then GSK shall surrender such regulatory approvals or applications for cancellation. To the extent that such are related to Licensed Product, all such data, files, materials, information, filings and approvals shall thereafter be deemed to be Unigene’s Confidential Information and subject to the confidentiality provisions of this Agreement, and shall be transferred to the possession of Unigene.

10.5.6. Trademarks. In the event of termination by GSK pursuant to Section 10.3 or 10.4, or by Unigene pursuant to Section 10.2 of 10.3, the parties shall negotiate in good faith for an assignment by GSK of GSK Marks which have been used commercially at or prior to said time and are specifically related to Licensed Product to Unigene (to the extent legally permissible in the relevant country) within a reasonable time after any termination of GSK’s rights under this Agreement. In the event of termination by Unigene pursuant to Section 10.2, GSK shall assign the GSK Marks specifically related to Licensed Product to Unigene within a reasonable time after termination of GSK’s rights under this Agreement at no cost or expense to Unigene.

10.6. Bankruptcy Provisions. All rights and distribution rights granted under or pursuant to the Agreement by Unigene to GSK are, and shall otherwise be deemed to be, for purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to “intellectual property” as defined under Section 101(52) of the U.S. Bankruptcy Code. The Parties agree that GSK, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code, subject to performance by GSK of its preexisting obligations under the Agreement. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Unigene under the U.S. Bankruptcy Code, GSK shall be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and same, if not already in its possession, shall be promptly delivered to GSK (a) upon any such commencement of a bankruptcy proceeding upon written request therefore by GSK, unless Unigene elects to continue to perform all of its obligations under this Agreement, or (b) if not delivered under (a) above, upon the rejection of this Agreement by or on behalf of Unigene upon written request therefore by GSK, provided, however, that upon Unigene’s (or its successor’s) written notification to GSK that it is again willing and able to perform all of its obligations under this Agreement, Unigene shall promptly return all such tangible materials to GSK, but only to the extent that Unigene does not require continued access to such materials to enable GSK to perform its obligations under this Agreement.

- 34 -

Sections 2.4; 3.2, 3.3, 3.4, 3.5, 3.7 and 3.10 (all to the extent owed or unpaid), 3.8 and 3.9 (both to the extent owed or unpaid, but only with respect to activities which occur during the Term), 3.11, 3.12, 3.13, 3.14; 6.1, 6.2, 6.3 (with respect to the representations and warranties therein); 6.5 and 6.6 (both only with respect to infringements which occur during the Term), 6.7 (as applied to any matters surviving under Sections 6.5 and 6.6); 7.1; 8.1 (for the time period provided therein), 8.2, 8.3, 8.5; and Articles 1, 9, 10 and 11 shall survive the expiration or termination of this Agreement for any reason.

11.10. Entire Agreement. This Agreement constitutes the entire agreement, both written or oral, with respect to the subject matter hereof, and supersedes and terminates all prior or contemporaneous understandings or agreements, whether written or oral, between GSK and Unigene with respect to such subject matter, including, but not limited to, that Confidential Disclosure Agreement dated October 18, 2001. No terms or provisions of this Agreement shall be varied or modified by any prior or subsequent statement, conduct or act of either of the Parties, except that the Parties may amend this Agreement by written instruments specifically referring to and executed in the same manner as this Agreement.
