(b) No later than nine (9) months prior to the projected filing date of the NDA in the United States, W-L shall provide Unigene with a good faith forecast estimating W-L's monthly requirements of the Raw Material (and the desired delivery dates) for the succeeding twelve (12) month period, which forecast W-L shall update no later than thirty (30) days prior to each Calendar Quarter; provided, however, that with respect to each quarterly update, W-L (a) may not change the forecast for the initial Calendar Quarter in the updated twelve (12) month period at all from the amount that W-L forecasted for such Calendar Quarter in its previous update, (b) may not change the forecast for the second Calendar Quarter by more than ten percent (10%) of the amount that W-L forecasted for such Calendar Quarter in its previous update, 25 and only to the extent that such change results in a forecast amount for such Calendar Quarter that is between ninety percent (90%) and one-hundred and ten percent (110%) of the amount that W-L forecasted for such Calendar Quarter in the update that preceded its previous update, and (c) may not change the forecast for the third Calendar Quarter in such period by more than twenty percent (20%) of the amount that W-L forecasted for such Calendar Quarter in its previous update. W-L shall promptly notify Unigene of any changes in the circumstances on the basis of which the forecasts were determined and which materially affect the amount of W-L's anticipated requirements, as reported in the forecasts given to Unigene hereunder, and W-L and Unigene shall work with each other to reach a mutually acceptable solution; provided, however, that W-L shall be obligated to purchase, and Unigene shall be obligated to sell, such quantities of the Raw Material as are set forth in the firm forecast, as such forecast may be amended from time to time pursuant to the preceding sentence. 3.4 Purchase Orders. (a) With respect to development supplies of Raw Material, W-L shall issue to Unigene a firm purchase order for purchases of such Raw Material during each month not later than thirty (30) days prior to the commencement of such month; provided, however, W-L shall be obligated to purchase at least such quantities of Raw Material as are set forth in the most 26 recent forecast pursuant to Section 3.2 for such month; and provided further that Unigene shall not be obligated to supply quantities of Raw Material in excess of such quantities of Raw Material as are set forth in the most recent forecast pursuant to Section 3.2 for such month.

(c) In the event that the terms of any purchase order issued pursuant to this Section 3.4 are not consistent with this Agreement, the terms of this Agreement shall prevail. 3.5 Delivery. Delivery of each order of Raw Material shall be made Ex Works (Incoterms 1990) at a facility to be designated by Unigene. Title to and risk of loss of the Raw Material shall pass to W-L at the time of delivery to the carrier. Unigene shall promptly invoice W-L for all Product 27 shipped. Invoices shall be accompanied by the certificate of analysis for each invoiced lot of Raw Material. 3.6 Inability to Supply. Unigene understands and agrees that a reliable source of Raw Material is critical to W-L. Should Unigene believe, at any time during the term of this Agreement, that it may be unable to supply W-L's forecasted requirements of Raw Material, then it shall advise W-L thereof and of the steps it will take to help insure that it will be able to continue to supply W-L's forecasted requirements of Raw Material. In the event that Unigene's manufacturing facility is destroyed or otherwise compromised, or is not adequate to produce W-L's reasonably forecasted requirements of Raw Material, Unigene shall use its best efforts to rebuild or expand its manufacturing facilities, as the case may be, or qualify a third party manufacturer, whichever is likely to enable Unigene more quickly to meet its supply obligations, taking into consideration the quantities of Raw Material forecasted by W-L together with any obligations Unigene may have to supply third parties with Raw Material; provided, however, that Unigene shall consult with W-L and keep W-L apprised concerning any steps that Unigene proposes to take in order to restore or expand its capacity to produce the Raw Material, including without limitation qualifying a third party manufacturer; and provided, further, that W-L agrees to cooperate with and provide reasonable assistance to Unigene in the event that Unigene seeks to 28 qualify a third party manufacturer. In the event that Unigene is unable to produce sufficient Raw Material to meet the orders of all of its customers, Unigene shall supply W-L on a priority basis with such quantities of Raw Material as Unigene is able to produce, up to the amounts required to manufacture the quantities of the Product corresponding to the sales levels set forth for the relevant year on Annex D hereto (and, for years thereafter, up to the amounts required to manufacture quantities of the Product corresponding to the sales levels set forth for the final year listed on Annex D hereto); provided, however, that in the event that such inability to supply shall result from a force majeure, as defined in Section 15.1, then Unigene shall supply W-L with its pro rata allocation of available Raw Material calculated based on the firm forecasts of W-L and Unigene's other customers. 3.7 Warranty. Unigene warrants that, at the time of delivery of the Raw Material to W-L: (i) the Raw Material will have been manufactured, stored and shipped in accordance with applicable Good Manufacturing Practices and all other applicable laws, rules, regulations or requirements of the FDA and other Regulatory Authorities which have granted Approvals, (ii) the Raw Material will have been manufactured in accordance with the specifications provided to W-L by Unigene for the Raw Material, and conform with the certificate of analysis provided pursuant to Section 3.5, (iii) the Raw 29 Material will not be adulterated or misbranded under the Federal Food, Drug, and Cosmetic Act, as amended, and similar provisions of the laws of other countries as to which Approvals have been granted; (iv) title to all Raw Material sold hereunder will pass to W-L as provided herein free and clear of any security interest, lien, or other encumbrance; and (v) the Raw Material will have been manufactured, stored and tested in facilities which are approved by the FDA and any other applicable Regulatory Authorities at the time of such manufacture, storage and testing, to the extent such approval is required by applicable law; provided, however, that to the extent that Unigene reasonably determines, after consultation with W-L, that requirements imposed by a Regulatory Authority (other than the FDA) in a country for approval of such facilities are materially inconsistent with those required by the FDA or are otherwise onerous, Unigene shall have the right to terminate this Agreement with respect to such country, by Notice to W-L, whereupon such country shall no longer be part of the Territory, provided that Unigene shall not terminate this Agreement pursuant to this Section 3.7 with respect to the United States, Canada, Europe or Japan. 3.8 Price. The parties agree that the purchase price for Raw Material during the term of the parties' respective purchase and supply obligations under Section 3.1 shall be [ ] per kilogram; provided, however, that in the event that W-L shall lower the 30 selling price of the Product (from the selling price of the Product then in force or, if such change is made prior to Launch, the selling price indicated in then-current W-L marketing projections) in a country in which Approval has been granted, in order to meet competition from one or more nasally-administered calcitonin products sold in such country by a third party under license from Unigene and/or using Raw Material purchased from Unigene, then the total payment by W-L to Unigene in respect of the Product sold by W-L, its Affiliates and Sublicensees in such country, on a per unit basis (equal to the sum of the transfer price of Raw Material used in the manufacturing thereof and the royalty payments pursuant to Section 6.1(b) with respect to Net Sales thereof) (the "Cost of Goods"), shall not exceed [ ], [ ], or [ ], as determined pursuant to Section 6.1(b)(i)(A)(a)-(c), of the Net Sales in such country; provided, further, that in no event shall Unigene be obligated to supply W-L with commercial supplies of the Raw Material at a purchase price lower than [ ] per kilogram; and provided, further, that the parties agree to determine and settle any amounts owing by one party to the other pursuant to the first proviso to this Section 3.8, within sixty (60) days after the end of each Calendar Quarter; and provided, further, that Unigene agrees to supply W-L until the third anniversary of the initial Launch of the Product with (a) up to a maximum of 250 grams of Raw Material at [ ] and 31 reasonable quantities of Raw Material in excess of 250 grams at [ ] per kilogram, all for use only in connection with W-L's Development Activities, and (b) up to a maximum of 50 grams of Raw Material at [ ] and reasonable quantities of Raw Material in excess of 50 grams at [ ] per kilogram, all for use only in the manufacture of Product promotional samples. Terms of payment shall be net thirty (30) days from the date of invoice. Unigene agrees that, during the term of the parties' respective purchase and supply obligations under Section 3.1, in the event it supplies Raw Material to any third party (including, without limitation, Unigene's licensee for the oral calcitonin product in the Semi-Exclusive Territory) for use in an oral calcitonin product to be sold or used in the Semi-Exclusive Territory for a total payment (including the transfer price thereof and any applicable royalty payment obligation) that is lower than [ ] of net sales (calculated on a basis similar to the calculation of Net Sales hereunder) of such product in the Semi-Exclusive Territory by such third party or its Affiliates, then the sum of the transfer price and royalty hereunder shall be reduced to that paid by such third party. Unigene shall notify W-L in writing promptly after entering into an agreement to supply Raw Material to a third party under circumstances that would trigger a reduction in the sum of the transfer price and 32 royalty hereunder to W-L under the preceding sentence. Further, W-L shall have the right, upon reasonable notice to Unigene, to cause an independent certified public accountant reasonably acceptable to Unigene to review the relevant books and records of Unigene to verify the accuracy of the reduction granted to W-L pursuant to the first sentence of this paragraph. In the event that W-L shall face price competition in the Marketing and sale of the Product in one or more countries in the Territory from nasally-administered calcitonin product(s) sold by a third party that is not a licensee of Unigene and not using Raw Material purchased from Unigene, then the parties agree to meet in order to discuss appropriate responses, including without limitation ways in which to make the Product more competitive. 3.9 Specifications Amendments. Unigene reserves the right to amend and/or supplement the Product Specifications as they relate to Raw Material unilaterally on six (6) months' prior written notice (or such shorter period as may be required by law) for the purpose of complying with Good Manufacturing Practices or the rules, regulations, guidelines or requirements of the Regulatory Authorities. Unigene may not otherwise amend and/or supplement the Product Specifications without the prior written approval of W-L, which approval shall not be unreasonably withheld. Unigene shall provide W-L with prior written notice of any amendments 33 or supplements that Unigene is considering and cooperate with W-L in order to ensure that, to the extent required, such changes are submitted to and approved by the relevant Regulatory Authorities. 3.10 Records. Unigene shall maintain, or cause to be maintained, all records necessary to comply with all applicable laws, rules and regulations in the United States relating to the manufacture of the Raw Material. All such records shall be maintained for such period as may be required by law, rule or regulation; provided, however, that all records relating to the manufacture, stability and quality control of each batch of the Raw Material supplied to W-L hereunder shall be retained at least until the first anniversary of the end of the approved shelf life for the Raw Material from such batch. 3.11 Third Party Raw Material Supply. Unigene shall use its best efforts consistent with applicable law to ensure that any Raw Material which Unigene may supply to a party other than W-L or any of its Affiliates or Sublicensees shall not be used to manufacture, Finish, use or sell the Product or any other oral calcitonin product in the Territory (other than the Semi-Exclusive Territory) in violation of the rights licensed and/or acquired by W-L under this Agreement. 3.12 Quality Assurance.

In any event, W-L shall commence Marketing of the Product in each country in the Territory as promptly and as expeditiously as possible after Approval has been granted in such country, and shall promptly give Unigene written notice of the date of Launch in each such country; provided, however, that, notwithstanding anything to the contrary contained herein or in the Marketing Plans, W-L shall Launch the Product (i) in each of the Priority Markets within six (6) months of the day on which the relevant Approval and any regulatory pricing approval required for governmental reimbursement in such country has been granted, (ii) in each Secondary Market in which clinical trials in addition to those performed in one or more of the Priority 35 Markets are required for Approval, within six (6) months of the day on which the relevant Approval and any regulatory pricing approval required for governmental reimbursement in such country has been granted, and (iii) in each Secondary Market in which no such additional clinical trials are required for Approval, within six (6) months of the later of (a) the day the first Approval that is referenceable in such Secondary Market, and (b) the day any regulatory pricing approval required for governmental reimbursement in such country, has been granted; provided, however, if W-L fails to Launch the Product in any Priority Market or Secondary Market within twelve (12) months of the date of grant of the relevant Approval for such country, Unigene shall have the right to terminate this Agreement with respect to such country pursuant to Section 14.2. (b) W-L shall, at its sole expense, obtain all Approvals necessary to accomplish the Marketing, distribution and sale of the Product in each country in the Territory, and any pricing approvals, or their equivalent, required in connection therewith in such country.

All such records shall be maintained for such period as may be required by law, rule or regulation; provided, however, that all records relating to the Finishing, stability and quality control of each batch of the Product shall be retained at least until the first anniversary of the end of the approved shelf life for the Product made from such batch. 4.3 Compliance. W-L and Unigene shall comply, and shall cause their Affiliates (and, in the case of W-L, Sublicensees, and, in the case of Unigene, its licensees in the Semi-Exclusive Territory) to comply, with all applicable laws, regulations and Approvals in conducting their respective activities relating to the manufacturing, Finishing, Marketing, distribution and sale of the Product in each country in the Territory, including, without limitation, all requirements as to pre-marketing approval of product labelling. 4.4 Marketing Plans, Marketing Reports and Launch Meetings.

(a) During the term of this Agreement and for three (3) years thereafter, W-L shall maintain, at its sole expense, clinical trial and product liability insurance relating to the Product that is comparable in type and amount to the insurance it maintains with respect to its most similar other prescription pharmaceutical products that are Marketed, distributed and sold in the Territory, and which names Unigene as an insured party, as its interests may appear.

(b) In consideration of the licenses and other rights granted herein and subject to the terms and conditions set forth in this Agreement, for each full or partial Calendar Quarter after the Launch of the Product in any country, W-L shall pay Unigene a royalty in an amount equal to the difference between: (i) the greater of (x) the Minimum Royalty Amount for such period, if any, and (y) the aggregate of the product of the Net Sales of the Product in such period in each country in the Territory and the applicable royalty rate set forth below: (A) during each Calendar Year continuing until the later to occur of (1) (I) in the case of each country in the Territory excluding Europe, the later of the tenth anniversary of the Launch of the Product in such country and the launch of another oral calcitonin product, the sales of which materially adversely affect the Net Sales of the Product in such country, and (II) in the case of each country in Europe, the tenth anniversary of the Launch of the Product in such country, and (2) the date on which there is no longer any Valid Claim in such country (a "Royalty Transition Date"), the royalty rate shall be as follows: a) On aggregate Net Sales of the Product of less than [ ], the royalty rate shall be [ ] for all countries in the Territory except countries in the Semi-Exclusive Territory, for which countries the royalty rate shall be [ ]; 45 b) on any increment of aggregate Net Sales of the Product between [ ] and [ ], the royalty rate shall be [ ] for all countries in the Territory except countries in the Semi-Exclusive Territory, for which countries the royalty rate shall be [ ]; c) on aggregate Net Sales of Product in excess of [ ], the royalty rate shall be [ ] for all countries in the Territory except countries in the Semi-Exclusive Territory, for which countries the royalty rate shall be [ ]; and d) after the date on which there is no longer any Valid Claim in a country, the applicable rate for such country under clauses a) through c) above shall be [ ] during each of the ten (10) successive twelve (12) month periods thereafter, provided that no royalty obligation shall continue under this Section 6.1(b) after the tenth anniversary of the date on which there is no longer any Valid Claim in such country. Provided, however, that, even after the Royalty Transition Date occurs in a country, the Net Sales in such country shall be included in the aggregate Net Sales for purposes of determining the appropriate royalty rate for those countries in which the Royalty Transition Date has not yet occurred (for purposes of illustration only, an example of an annual royalty calculation after the Royalty Transition Date has occurred in part but not all of the Territory is attached as Annex E hereto); and provided further the Net Sales in the Semi-Exclusive Territory shall be included in the aggregate Net Sales for purposes of determining the appropriate royalty rates for all countries in the Territory; and provided further that if applicable law so permits, then the Royalty Transition Date for each of the countries in Europe shall be determined in the manner set forth in Section 6.1(b)(i)(y)(A)(1)(I); and 46 (B) after the Royalty Transition Date in a country, the royalty rate in such country shall be zero. AND (ii) any amounts paid to Unigene pursuant to Section 3.8 for Raw Material contained in such Product. W-L shall pay any amounts owed to Unigene pursuant to this Section 6.1(b)(i)(y) on a quarterly basis within sixty (60) days following the end of each full or partial Calendar Quarter during the term of this Agreement. If, for the twelve (12) month period commencing on the first day of the first full Calendar Quarter after the Launch in each of the United States, Europe and Japan, or the twelve (12) month periods beginning on the first and second anniversary thereof, the amounts paid under Section 6.1(b)(i)(y) do not exceed the amounts stated in Section 6.1(b)(i)(x) for such country or Europe for such period, W-L shall pay the difference within forty-five (45) days of the end of the relevant twelve (12) month period. Net Sales made in foreign currencies shall be converted into United States Dollars using the average of the exchange rates set forth in the United States eastern edition of The Wall Street Journal for the last business day of the full or partial Calendar Quarter in which such Net Sales were booked and the last business day of the previous Calendar Quarter. 47 With respect to any partial Calendar Quarter or Calendar Year, any Minimum Royalty Amount and Net Sales thresholds for the royalty rate adjustments for such period shall be prorated to reflect the percentage of such period that elapsed before this Agreement terminated. (By way of example, and not in limitation of the parties' rights hereunder, if this Agreement were terminated at the end of the sixth month in any twelve month period, both the Minimum Royalty Amount, if any, and the Net Sales thresholds (but not the corresponding royalty rates) for such period would be reduced by fifty percent (50%).) Each payment hereunder shall be accompanied by written report, certified by an officer of W-L or his or her designee, providing a detailed breakdown of the Net Sales, and the components thereof, during such period. 6.2 Withholding Taxes. W-L shall pay any and all withholding taxes or similar charges imposed by any governmental unit in the Territory on any amounts due to Unigene from W-L pursuant to this Section 6 to the proper taxing authority, and proof of payment of such taxes or charges shall be secured and sent to Unigene as evidence of such payment.

It is anticipated that members of the Development Team will be employees of Unigene or W-L, will be multi-disciplinary in their fields of expertise, and will have appropriate technical credentials and knowledge and ongoing familiarity with the objectives of the Development Plan. 7.2 Authority of the Development Team. The Development Team shall (i) manage the day-to-day Development Activities and perform such other activities as Unigene and W-L may mutually agree, (ii) approve any changes in the Development Plan, (iii) formulate recommendations or proposals for W-L management related to (A) all formulations of the 49 Product used in the Phase I Clinical Trials and their foreign equivalents, and the final formulations of the Product used in the Phase III Clinical Trials and their foreign equivalents, (B) the protocol and design of all clinical trials, and (C) the labelling and packaging of any finished formulation of the Product, and (iv) take such other actions as are set forth herein or as the parties may mutually agree, except that the Development Team may not take any action that would conflict with any provision of this Agreement. 7.3 Procedural Rules of the Development Team. (a) The Development Team shall take action by consensus of the members present; provided, however, that final decision-making authority with respect to decisions and actions of the Development Team shall reside with W-L. (b) The Development Team shall meet at least monthly or as otherwise agreed by the Development Team Leaders, at times and places mutually agreed upon, to discuss the overall progress of the Development Activities, the status of the Development Plans, any problems arising in the course of the Development Activities, and any other matter that a member of the Development Team may reasonably request. Notwithstanding the foregoing, the parties shall regularly exchange minutes of the monthly meetings and Status Reports every four months regarding the Development Team Activities. (c) Members of the Development Team may attend meetings in person, by telephone or by video conference.

SECTION 9 ADVERSE EVENT AND OTHER INFORMATION EXCHANGE 9.1 Notification. Each party shall provide prompt Notice to the other party of information in or coming into its possession or control concerning any unusual or unexpected reaction or side effect, customer complaint, reported defect, adverse reaction, injury or toxicity or sensitivity reaction associated with commercial and clinical uses, studies, 52 investigations or tests of the Product (animal or human), whether or not determined to be attributable to the Product, and whether arising out of clinical studies or Marketing and sale of the Product. Further, each party shall notify the other's responsible drug safety department (or in the case of Unigene, its chief executive officer), by facsimile, with a confirmation copy by mail, such notice to include a copy of the complaint, as soon as possible, but in no event later than four (4) calendar days (and in those countries in which the Regulatory Authorities require shorter notice, each party shall provide the other with Notice within twenty-four (24) hours), after the time a party first becomes aware of any information concerning any serious and/or unexpected side effect, injury, toxicity or sensitivity reaction or any unexpected incidence, and the severity thereof, associated with the Product. "Serious" as used in this Section 9.1 shall refer to an experience which (i) is fatal or immediately life threatening; (ii) requires or prolongs inpatient hospitalization; (iii) results in persistent or significant disability and/or incapacity; (iv) is a congenital anomaly and/or birth defect, cancer or overdose (intentional or accidental); or (v) is considered a medically significant event (includes laboratory abnormalities). Medically significant events are those which may not be immediately life threatening or result in death or hospitalization but may jeopardize the patient or may require intervention to prevent 53 one of the outcomes listed above to define Serious. By way of illustration and not limitation, examples of medically significant events are: intensive treatment in an emergency room or at home for allergic bronchospasm, blood dyscrasia, convulsions that do not result in hospitalization, development of drug dependency or drug abuse or laboratory abnormalities. Information concerning other complaints and other adverse reactions regarding the Product shall be exchanged between the parties in writing promptly, but in any event not less frequently than monthly. W-L shall be responsible for reporting adverse experiences with respect to the Product to the FDA in conformance with applicable law; provided, however, that each party shall make such reports as are necessary to comply with laws and regulations applicable to it, at its sole expense. Each party shall promptly provide the other with any information concerning any adverse experiences as described above with respect to the Product or the Compound from outside the Territory, which is known to such party, within four (4) calendar days after receipt of notice thereof.

Upon receipt of any such information, the parties shall consult in an effort to arrive at a mutually acceptable procedure for taking appropriate action; provided, however, that nothing set forth in this Section 9.2 shall be construed as restricting the right of either party to make a timely report of such matter to any government agency or take other action that it deems appropriate or required by applicable law or regulation. 9.3 Material Communications. In addition to the notifications required by Section 2.6, each party shall promptly provide Notice to the other party of any material communications with any governmental agency concerning the Product, including, without limitation, adverse drug reaction reports. Copies of all such material communications shall be attached to the Notice sent pursuant to this Section 9.3. SECTION 10 PRODUCT RECALL 10.1 Notification and Recall. (a) In the event that any governmental agency or authority issues or requests a recall or takes similar action in connection with the Product, or in the event either party determines an event, incident or circumstance has occurred which may result in the need for a recall or market withdrawal, the party notified of or calling such recall or similar action shall, within three hours, advise the other party thereof by telephone or facsimile. 55 (b) Following notification pursuant to Section 10.1(a), within forty-eight (48) hours, the parties' representatives from business, medical, regulatory, quality assurance and legal functions (and any others deemed necessary by a party) shall discuss whether or not to conduct a recall (except in the case of a government-mandated recall), and if so, the timing of the recall, the breadth, extent and level of customer to which the recall shall reach, the strategies and notifications to be used, and other related issues. In the event that such representatives cannot agree on any such decision, the issue shall be resolved by senior management of W-L. (c) In the event that Unigene recommends that a recall be conducted in connection with a problem or potential problem with the Raw Material that Unigene has identified, and W-L decides not to conduct a recall of the Product, then W-L shall indemnify Unigene pursuant to Section 13.4 from and against all Losses that Unigene may incur as a result of any such failure by W-L to conduct a recall. (d) Nothing set forth in this Section 10.1 shall be construed as restricting the right of either party to make a timely report of such matter to any government agency or take other action that it deems appropriate or required by applicable law or regulation. 10.2 Recall Expenses. W-L shall bear the expenses of any recall of Product; provided, however, that Unigene 56 shall bear the expense of a recall to the extent that such recall resulted from Unigene's breach of its obligations hereunder. Such expenses of recall shall include, without limitation, the expenses of notification and destruction or return of the recalled Product and the refund to consumers of amounts paid for the recalled Product.

Each party shall keep the other party currently informed of all steps to be taken in the preparation and prosecution of all applications filed by it according to this Section 11 and shall furnish the other with copies of such applications for Patents, amendments thereto and other related correspondence to and from patent offices and permit the other party to offer its comments thereon before a party makes a submission to a patent office which could materially affect the scope or validity of the patent coverage that may result. Each party shall offer its comments promptly. All determinations regarding whether or not an Improvement is a Sole Improvement or a Joint Improvement shall be made in accordance with the patent laws of the United States. 11.2 Ownership of and Validity of Trademarks.

(a) In the event of any infringement by a third party of any intellectual property rights relating to the Product or the Compound, or any data related thereto or developed as a result of or in connection with the Project Activities in the Territory, including without limitation the Licensed Technology, the Unigene Regulatory Documentation, any Project Information and Inventions owned or controlled solely by Unigene or licensed to Unigene (other than Project Information and Inventions licensed to Unigene pursuant to Section 11.4(b)), Unigene shall have the first right (but not the obligation) to pursue any and all injunctive, compensatory and other remedies and relief (collectively, "Remedies") against such third party. If Unigene shall determine not to pursue Remedies with respect to any such infringement within 61 sixty (60) days after Notice from W-L requesting Unigene to do so, then W-L shall have the right (but not the obligation) to pursue Remedies against such third party. (b) In the event of any infringement by a third party of any intellectual property rights relating to W-L Regulatory Documentation and Project Information and Inventions owned or controlled solely by W-L or jointly by Unigene and W-L, W-L shall have the first right (but not the obligation) to pursue any and all Remedies against such third party. Should W-L determine not to pursue Remedies with respect to any such infringement within sixty (60) days after Notice from Unigene requesting W-L to do so, then Unigene shall have the right (but not the obligation) to pursue Remedies against such third party. (c) In the event that a party shall pursue Remedies hereunder, the other party shall use all reasonable efforts to assist and cooperate with the party pursuing such Remedies. Each party shall bear its own costs and expenses relating to such pursuit. Any damages or other amounts collected shall be distributed, first, to the party that pursued Remedies to cover its costs and expenses and, second, to the other party to cover its costs and expenses, if any, relating to the pursuit of such Remedies; any remaining amount shall be distributed to the party that pursued the Remedies. 62 11.6 Infringement of Third Party Rights. (a) If one or more patents covering the Marketing or sale of the Product, but not the Raw Material itself, has issued to a third party in the Territory and if W-L reasonably determines that it is advisable to obtain a license from such third party under such patent or patents, then W-L shall devote all reasonable efforts to obtaining a license from such third party. W-L shall be solely responsible for all royalties and other payments to a third party under any license resulting from the provisions of this Section 11.6(a). If W-L determines that such a license is unnecessary, W-L may agree to indemnify Unigene for any and all liability that Unigene might incur in connection with the manufacture or sale of the Raw Material by Unigene or the marketing or sale of the Product by W-L in the absence of such a license. In the event that W-L determines that such a license is unnecessary and does not agree to indemnify Unigene in accordance with the preceding sentence, then Unigene may terminate this Agreement with respect to the country or countries involved, pursuant to Section 14.4(a). In the event that W-L determines that such a license is necessary and (i) the patent owner is unwilling to grant such a license, or (ii) the cost of such a license would render the Product commercially infeasible, then either W-L or Unigene may terminate this Agreement with respect to the country or countries involved, pursuant to Section 14.4(a). 63 (b) If one or more patents covering the Raw Material has issued to a third party in the Territory and if Unigene reasonably determines that it is advisable to obtain a license from such third party under such patent or patents, then Unigene shall make the necessary arrangements to obtain such license under such third party patent rights so that Unigene may continue to meet its supply obligations hereunder. Any costs for such license or sublicense shall be the sole responsibility of Unigene. In the event that Unigene, despite its reasonable efforts, is unable to obtain such a license, then W-L may use its commercially reasonable efforts to obtain such a license from such third party and, if it shall obtain such a license, it shall grant a sublicense thereunder to Unigene, and Unigene and W-L shall be responsible, respectively, for seventy-five percent (75%) and twenty-five percent (25%) of the payments to such third party thereunder. If W-L is not able to, or elects not to negotiate such a license, then Unigene may terminate this Agreement with respect to the country or countries involved, pursuant to Section 14.4(a). (c) In the event that a third party institutes or threatens a patent, trade secret or other infringement suit against W-L or its Affiliates or Sublicensees during the term of this Agreement, alleging that their Marketing, sale or use of the Product in the Territory infringes one or more patent or other intellectual property rights held by such third 64 party, then W-L shall have the first right (but not the obligation), at its sole expense, to assume direction and control of the defense of claims arising therefrom (including the right to settle such claims at its sole discretion); provided, however, that W-L shall obtain the written consent of Unigene prior to ceasing to defend, settling or otherwise disposing of such claims; provided, further, that if Unigene shall refuse to provide such consent, then Unigene shall indemnify W-L pursuant to Section 13.3 for any and all Losses that W-L, its Affiliates or Sublicensees may suffer as a result of such refusal. If W-L determines not to assume such direction and control, Unigene shall have the right, at its sole expense, to defend, settle or otherwise dispose of such claims on such terms as Unigene, in its sole discretion, shall deem appropriate. In the event that W-L controls the defense of an action challenging claims under the Unigene Patents, all of the reasonable expenses and costs, including, without limitation, attorneys' fees and damage awards, incurred by W-L in connection therewith that are not offset by proceeds therefrom shall be creditable against the royalties due under Section 6.1(b); provided, however, that no royalty payment when due, regardless of the amount or number of credits available to W-L in accordance with this Agreement, shall be reduced by more than fifty percent (50%). (d) In the event that a third party institutes a patent, trade secret or other infringement suit against 65 Unigene, W-L or their respective Affiliates or sublicensees during the term of this Agreement, each party shall, at its own cost and expense, use all reasonable efforts to assist and cooperate with the other party in connection with the defense of such suit. (e) If (i) as a result of any claim made against W-L or any of its Affiliates or Sublicensees during the term of this Agreement alleging that the Marketing or sale of the Product by such entity infringes or misappropriates any patent or any other proprietary right of a third party, a judgment is entered by a court of competent jurisdiction from which no appeal is taken within the time permitted for appeal, such that W-L cannot sell the Product in a Priority Market without infringing the patent or other proprietary rights of such third party, and (ii) Unigene and/or W-L are unable to obtain the license referred to in this Section 11.6 within sixty (60) days after such entry of judgment, or such consideration to be paid to a third party for such license would make the Product commercially impracticable, then W-L shall have the right for thirty (30) days after the expiration of such sixty (60) day period to terminate this Agreement by written Notice to Unigene. (f) Nothing in this Section 11.6 shall prevent either party, at its own expense, from obtaining any license or other rights from third parties it deems appropriate in 66 order to permit the full and unhindered exercise of its rights under this Agreement. (g) The provisions of this Section 11.6 set forth the parties' exclusive and sole remedies against each other in respect of the subject matter thereof.

Notwithstanding anything to the contrary in this Section 12, Unigene and its Affiliates shall have the right to use and disclose any and all Licensed Technology and, to the extent not included therein, all Unigene Regulatory Documentation and any Project Information and Inventions solely owned or controlled by or licensed to Unigene (other than pursuant to Section 11.4(b)) relating to the Product or the Compound or any Improvements thereto in accordance with the terms of this Agreement, without obtaining the consent of W-L. 12.4 Notification. The Receiving Party shall notify the Disclosing Party immediately, and cooperate with the Disclosing Party as the Disclosing Party may reasonably request, upon the Receiving Party's discovery of any loss or compromise of the Disclosing Party's information. 12.5 Remedies. Each party agrees that the unauthorized use or disclosure of any material information by the Receiving Party in violation of this Agreement will cause severe and irreparable damage to the Disclosing Party. In the event of any violation of this Section 12, the Receiving Party agrees that the Disclosing Party shall be authorized and 70 entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, as well as any other relief permitted by applicable law. The Receiving Party agrees to waive any requirement that the Disclosing Party post bond as a condition for obtaining any such relief. 12.6 Return of Information. Within thirty (30) days of the termination of this Agreement, each party shall return to the other party any and all copies of information covered by this Section 12 or otherwise owned by the other party, including, without limitation, all Regulatory Documentation and any Project Information and Inventions solely owned or controlled by or licensed (other than pursuant to Section 11.4) to the other party. 12.7 Survival.
