2.2. Sublicenses.

(a) The licenses granted to Salix in Section 2.1 shall include the right to grant Sublicenses through multiple tiers of Sublicensees (i) in the Human Field in the Territory other than the United States and (ii) in the Non-Human Animal Field in the Territory. In order to facilitate the operation of the provisions of Section 6.4, Salix agrees that it will not “bundle” a Product for Sublicensing with one or more other products that are not Products or offer a Product for Sublicensing to encourage the licensing or sublicensing by the Sublicensee of one or more products that are not Products without first reaching an agreement with Progenics, to be negotiated between Progenics and Salix in good faith, in respect of the appropriate allocation, in accordance with Applicable Law, the definition of “Sublicense Revenue,” and Section 6.4, of the gross amount to be received by Salix under any such arrangement between the Product and other products in the bundle or group.

(b) Salix shall, to the extent practical, inform Progenics reasonably in advance of the execution of any Sublicense that Salix expects to grant under this Agreement in respect of a Major Market Country or [*] or [*] and shall promptly (and, in the case of material items, within [*] ([*]) Business Days) provide to Progenics (i) notice of any Sublicense granted by Salix under this Agreement setting forth in reasonable detail the nature of such Sublicense and the identity of the Sublicensee and (ii) unredacted English-language copies of any agreement with a Third Party granting such Sublicense.

For the avoidance of doubt, in respect of the operation of clause (C) of this Section 2.2(c)(ii) the Parties agree and acknowledge that the combined effective royalty rate under the 1985 Agreement and the [*] Agreement as such agreements exist on the Effective Date for the [*] and [*] is [*]%.

(d) Salix hereby guarantees the performance of its Sublicensees and shall remain responsible to Progenics for full compliance with the terms of this Agreement, including all diligence, payment and reporting obligations. No Sublicense granted by Salix hereunder shall relieve Salix of any of its obligations under this Agreement.

(e) The Parties agree that appointment by Salix of any bona fide pharmaceutical wholesalers or providers of pharmaceutical distribution services shall not constitute a sublicense for purposes of this Section 2.2.

right to Sublicense as set forth in Section 2.2) directly to wholly owned Affiliates of Salix by giving notice designating to whom a direct license is to be granted. Upon receipt of any such notice, Progenics shall enter into and sign a separate direct license agreement with such designated Affiliate of Salix. All such direct license agreements shall be consistent with the terms and conditions of this Agreement, except for such modifications as may be required by Applicable Law; provided, however, that Progenics shall have no obligation to enter into any such direct license agreement if the effect of entering into such agreement (and continuing as a Party to this Agreement) would be to increase the level of obligations owed by or risks assumed by Progenics, or decrease the consideration owed to Progenics, relative to the obligations owed by, risks assumed by, or consideration owed to Progenics under this Agreement or otherwise adversely affect Progenics. In countries where validity of the direct license agreement requires governmental approval or registration, such direct license agreement shall not become binding between the parties thereto until such approval or registration is granted, which approval or registration shall be obtained by Salix. All costs of making a direct license, including Progenics’s reasonable attorneys fees, under this Section 2.3 shall be borne by Salix.

Progenics shall timely notify Salix of any sublicenses. An agreement with any sublicensee shall provide that such sublicense is consistent with and subject to the material terms and conditions of this Agreement, including without limitation the material obligations of Progenics hereunder.

2.6. Enforcement of Non-Assertion of Rights Covenants. Each Progenics Party shall cooperate with Salix and take such actions as Salix may reasonably request, and Salix shall reimburse each Progenics Party’s reasonable costs resulting from actions so requested, as may be necessary to permit Salix to exercise, for the benefit of Salix and its Affiliates and Sublicensees, the Progenics Parties’ rights (a) under the Termination Agreement to prevent Wyeth from

asserting any Wyeth Independent Patent Rights against the Progenics Parties or any of their licensees and (b) under the Ono Agreement to prevent Ono from asserting any Ono Independent Patent Rights against the Progenics Parties or any of their licensees. For the avoidance of doubt, this Section 2.6 shall require the Progenics Parties to consent to be joined, with the Progenics Parties’ reasonable costs to be reimbursed by Salix, as a party to any action required to enforce the rights identified in the preceding sentence, but shall not obligate any Progenics Party to indemnify or defend Salix in respect of any such action.

2.7. Non-Assertion of Progenics’s Rights; Non-Exclusive License Grant; Non-Assertion by Salix.

(a) Non-Assertion of Progenics’s Rights.

(b) Non-Exclusive License from Salix to Progenics. In the event that the exercise by Progenics, its Affiliates, licensees (including Ono), or sublicensees of the rights granted by Salix in Section 2.5 would infringe any Patent Rights Controlled by Salix or its Affiliates, and which Patent Rights are not covered by the grant in Section 2.5, Salix hereby grants to Progenics, its Affiliates, licensees and sublicensees to the extent Salix is legally able to do so, a non-exclusive, sublicensable, royalty-free license outside the Territory under such Patent Rights solely to the extent necessary for Progenics, its Affiliates, licensees and sublicensees to exploit the rights granted to Progenics and its Affiliates under Section 2.5.

(c) Non-Assertion by Salix.

Progenics as provided in this Section 2.9(a) shall be accomplished through: (i) the transfer of [*] and [*]; and (ii) the delivery of [*] and [*]. In addition, Progenics shall use Commercially Reasonable Efforts to cause Wyeth and Ono to provide, for delivery to Salix, relevant [*] and [*]. The provisions of this Section 2.9 are in addition to, and not by way of limitation of, the provisions of the Transition Agreement.

(b) By Salix. During the Term, Salix shall promptly disclose to Progenics any Joint Know-How and Salix Collaboration Know-How.

If Salix shall request that a Progenics Party perform any other activities in connection with the Collaboration or the Commercialization and Development of the Compound or any Product, then Salix shall reimburse the applicable Progenics Party for any and all costs the Progenics Party incurs, including out-of-pocket costs (including travel) and personnel costs at the FTE Rate. Salix shall reimburse the applicable Progenics Party for such costs within [*] ([*]) days of Salix’s receipt of an invoice therefor accompanied by reasonable documentation. Salix shall have no obligation to reimburse any Progenics Party for any costs that may be incurred by the Progenics Parties or their Affiliates in respect of any activity, whether or not relating to the Collaboration, that is not specifically requested by Salix in writing.

2.11. No Implied Rights. Except as expressly provided in this Agreement, neither Party shall be deemed to have granted the other Party any license or other right with respect to any intellectual property of such Party.

2.12. Japan. Provided that Salix is at such time in compliance in all material respects with its obligations under this Agreement, in the event that at any time the Ono Agreement should terminate or be modified with the result that rights in respect of the Development, Commercialization or Manufacture of Products in Japan licensed or otherwise granted by Progenics to Ono pursuant to the Ono Agreement revert to or otherwise come to be Controlled, directly or indirectly and in any manner whatsoever, by Progenics or its Affiliates, then the terms of this Agreement shall automatically, without further action by either Party and without any further payment by or on behalf of Salix, be, and they are hereby, amended to expand and extend the license grants, territory and other rights of Salix set forth in this Agreement to cover and include the license grants, territory and other rights so reverting to or otherwise coming to be Controlled, directly or indirectly, by Progenics or its Affiliates. In connection with any acquisition by Salix of rights in respect of Japan pursuant to this Section 2.12, Progenics shall use its good faith efforts to ensure the transfer and conveyance to Salix of all such rights in Regulatory Approvals, trademarks, trade names and similar intellectual property rights, rights under Third Party agreements relating to Products or their Development, Commercialization or Manufacture, and Clinical Data, Know-How and other information relating to Products, in each case relating to Japan, which Progenics may Control or have the right to transfer or assign or with respect to which Progenics may reasonably be able to obtain Control or the right to transfer or assign.

During such [*] ([*]) day period, Progenics shall negotiate exclusively with Salix and shall not pursue negotiations with, nor provide information regarding the licensing opportunity to, any other Person.

(iv) If (A) Salix does not provide timely notice of its exercise of its right of first negotiation or (B) the Parties are unable to conclude an agreement in respect of such license during the [*] ([*])-day period specified in Section 2.13(a)(iii) and, in the case of this clause (B), Salix does not notify Progenics that it wishes to continue negotiations with Progenics, Progenics shall then be free to pursue and enter into agreements with Third Parties and Salix shall have no further rights in respect of such New Progenics OIC Product.

Nothing in this clause (b) shall obligate Progenics to enter into any agreement with Salix in respect of any product or compound addressed hereby or condition or delay Progenics’s right to pursue discussions with any other Person in respect of a license or similar right in respect of any product or compound as to which it may have provided a notice to Salix hereunder.

Furthermore, Salix shall be relieved of its obligation to use Commercially Reasonable Efforts in any particular country with respect to a particular Product if a Third Party Controls Patent Rights as to which, in the written reasoned opinion of Salix’s outside patent counsel (which written opinion shall be reasonably acceptable to Progenics), there is a reasonable risk that a court would find the making, using or selling of such Product in such country to constitute an infringement and Salix or its Affiliates or Sublicensee(s) are unable to obtain a license under such Patent Rights on commercially reasonable terms or configure the Product so as to avoid infringement through the use of Commercially Reasonable Efforts.

(e) Unforeseen Events. The Parties recognize that the Development Plan and the objectives to be set forth therein are based upon numerous assumptions which are not in the control of the Parties. In view of the numerous assumptions underlying the Development Plan, the proposed timeframe for achieving the objectives and events described in the Development Plan will be regularly reviewed by the JDC in light of unforeseen matters. In the event that despite the use of Commercially Reasonable Efforts by the Parties, [*], or other issues beyond the control of the Parties arise that prevent either Party from fulfilling the objectives of the Development Plan within the timeframe set forth in the Development Plan, the JDC will discuss any appropriate revisions to the Development Plan, which revisions the other Party shall not unreasonably oppose, provided that the Party can demonstrate its use of Commercially Reasonable Efforts to Develop the Products.

4.3. Records. Salix and its Affiliates shall maintain, and shall use Commercially Reasonable Efforts to cause (a) their Outside Contractors to maintain and (b) Salix’s Sublicensees to cause such Sublicensees’ respective Outside Contractors to maintain, accurate and complete records of all activities related to the Development of Products, consistent with the responsibilities of Salix under this Agreement, and all results of any trials, studies and other investigations conducted under this Agreement by or on behalf of Salix, its Affiliates, Sublicensees and Outside Contractors, as applicable.

4.4. Reports on Development.

(a) For so long as Salix continues to Develop a Product under this Agreement, it shall in respect of such Product provide the JDC with reports containing

relevant information in reasonable detail regarding [*] and [*], [*], and [*] related to Registrational Filings and Clinical Trials of such Product conducted or overseen by Salix and its Affiliates and Sublicensees. Such reports shall be provided by Salix to the JDC as and when such reports are produced by or made available to Salix for its internal use.

(b) In addition, through its representatives on the JSC, each Party shall make reports to the JSC, as and at such time as such reports are produced by or made available to such Party for its internal use and otherwise on a periodic basis, updating the JSC as to the status and results of Development efforts of such Party and its licensees and Sublicensees (other than, in the case of Progenics, Salix and, in the case of Salix, Progenics) with respect to Products.

4.5. Transfer of Data. Without limiting the provisions of Sections 2.9(a) or 12.5(b), as soon as reasonably practicable, but in any event within [*] ([*]) days, following the Effective Date, Progenics shall, at its expense, provide Salix with access to, and (to the extent requested by Salix) copies of, all [*] and [*] relating to the Compound and Products to the extent the same is in the possession or Control of Progenics or its Affiliates. In addition, Progenics shall use Commercially Reasonable Efforts to cause Wyeth and Ono to provide, for delivery to Salix, relevant [*] and [*] which Wyeth and Ono are obligated, under the Wyeth Agreement, the Termination Agreement, and the Ono Agreement, respectively, to provide to Progenics. The provisions of this Section 4.5 are in addition to, and not by way of limitation of, the provisions of the Transition Agreement.

4.6. Ongoing Development Work.

(a) Subject to Ono’s rights under the Ono Agreement and the Initial Development Outline, all ongoing Development work in respect of the Compound or Products that is being conducted by the Progenics Parties or their Affiliates or licensees as of the Effective Date, including any pre-clinical or clinical studies and Clinical Studies (as such term is defined in Section 9.2(p)) identified on Schedule 9.2(p), shall either, as Salix may direct by notice to the Progenics Parties, be continued, terminated or transferred and transitioned to Salix.

(b) Subject to the provisions of Section 4.6(c), all ongoing Development work continued by the Progenics Parties as aforesaid and any termination or transfer and transition of ongoing Development work effected pursuant to Section 4.6(a) shall be at [*] sole cost and expense at the relevant [*] or the [*], as applicable.

(c) In respect of any ongoing Development work continued by the Progenics Parties as to which the Progenics Parties continue to have the right to receive reimbursement from Wyeth pursuant to the Termination Agreement, the Progenics Parties shall remain responsible for all costs and expenses of such Development work up to the amount of reimbursement that Wyeth is obligated to pay to the Progenics Parties in respect

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

thereof under the terms of the Termination Agreement. Salix shall be responsible, in accordance with Section 4.6(b), for any and all amounts in excess of such amounts that are reimbursable by Wyeth. In the event that the Progenics Parties should be unable to collect from Wyeth, because of Wyeth’s bankruptcy or insolvency, any amount that Wyeth is required to reimburse to the Progenics Parties under the Termination Agreement for Development work that has been conducted by the Progenics Parties as contemplated by the first sentence of this Section 4.6(c), then Salix shall pay such amount to the Progenics Parties and shall, by virtue of such payment, be subrogated to any rights that the Progenics Parties may have against Wyeth in respect of the amount so paid.

(d) Each Progenics Party shall reasonably cooperate with Salix to effect the transfer and termination of any ongoing Development work that Salix directs is to be transferred and transitioned to it. Without limitation, each Progenics Party shall use its reasonable efforts to assign and delegate to Salix or its Affiliates, as Salix may direct, all of the rights and obligations of the Progenics Party or its Affiliates or licensees, as the case may be, under such Progenics Third Party Agreements (other than the Subject Agreements) as Salix may determine are relevant to the conduct of ongoing Development work to be transferred and transitioned to it. The Progenics Parties and Salix shall use their respective reasonable efforts to obtain the consent of any relevant Third Party to the assignment and delegation of any such Progenics Third Party Agreement. In connection with obtaining any such consents, Salix shall cooperate with the Progenics Parties in obtaining from the relevant Third Party a release of the relevant Progenics Parties from liability under the relevant Progenics Third Party Agreement with respect to matters arising after the relevant assignment effective date, and, notwithstanding and in addition to the foregoing, shall, at Salix’s expense, cause the relevant Progenics Parties to be released from liability under the Progenics Third Party Agreements identified on Schedule 4.6(d) with respect to matters arising after or related to the relevant assignment effective date. To the extent any such Progenics Third Party Agreement is not assignable without the consent of a Third Party and the consent of such Third Party cannot be obtained following the reasonable efforts contemplated hereby, the performance obligations of the Progenics Parties or their Affiliates under such Progenics Third Party Agreement shall, unless not permitted by such Progenics Third Party Agreement, be deemed to be subcontracted to Salix until such Progenics Third Party Agreement can be effectively assigned and delegated. If any such consent cannot be timely obtained, (i) the Progenics Parties shall waive any exclusivity provision contained in the relevant Progenics Third Party Agreement to allow Salix to enter into its own agreement with the relevant Third Party and (ii) the Progenics Parties and Salix shall cooperate in any reasonable arrangement designed to provide for Salix the benefits and obligations intended to be assigned or delegated to and assumed by it in respect of such Progenics Third Party Agreement, including the right to enforce such Progenics Third Party Agreement for its own account. In furtherance of the foregoing, in respect of any Progenics Third Party Agreement that cannot be effectively assigned or delegated as contemplated hereby, the Progenics Parties hereby consent to the use by any Third Party which is a party to such Progenics Third Party Agreement of confidential information, technology and/or Know-How developed or held by such Third Party under the Progenics Third Party Agreement for the benefit of Salix, subject to applicable confidentiality and use restrictions. Notwithstanding any of the foregoing provisions of this Section 4.6(d), the Progenics Parties shall not be obligated to take or to permit to be taken any action which would, in the reasonable judgment of the Progenics Parties, be likely to result in a breach of any Progenics Third Party Agreement.

(e) Any transfer or transition of ongoing Development work from Progenics or its Affiliates or licensees to Salix pursuant to this Section 4.6 shall not affect the liability of the transferring party for any matters arising prior to the effective date of such transfer, and Salix shall have no liability in respect of any such matter. Conversely, any such transfer or transition shall result in Salix, as between it and the transferring party, being liable for all matters arising in respect of such Development work on or after the effective date of such transfer, provided, however, that, as between Salix and the transferring party, the transferring party shall remain solely liable for any matters arising before or after such transfer in respect of Development work transferred by the transferring party to Salix to the extent any such matter is a result of any act or omission on the part of the transferring party, its Affiliates, licensees, sublicensees or its or their directors, officers, employees or agents.

(f) The provisions of this Section 4.6 are in addition to, and not by way of limitation of, the provisions of the Transition Agreement.

(c) Adjustment of Royalties.

In the event that a Progenics Party or any of its Affiliates fails to pay any amount that it is obligated to pay in respect of a Progenics Third Party Agreement pursuant to the preceding sentence and Salix makes such payment on behalf of such Progenics Party, then Salix shall be entitled to credit such amount against any amount owed by Salix to Progenics under this Agreement. Except as otherwise provided herein, Salix shall, as between the Parties, be solely responsible in respect of all Progenics Third Party Agreements assigned to Salix pursuant to Sections 4.6(d) and 9.4(d) for any and all obligations arising under such Progenics Third Party Agreements from and after the date of assignment. In the event that Salix or any of its Affiliates fails to pay any amount that it is obligated to pay in respect of a Progenics Third Party Agreement pursuant to the preceding sentence and Progenics or one of its Affiliates makes such payment on behalf of Salix or such Affiliate, then Salix shall promptly reimburse Progenics for the amount paid.

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

effective royalty rate in respect of each such Quarter under Section 6.5(a) for such Product(s) as adjusted pursuant to Section 6.5(c) being reduced by not more than [*] ([*]) percentage points. By way of example, if the royalty rate applicable in respect of the relevant Quarter was [*] percent ([*]%), then the maximum amount in respect of amounts paid by Salix to the Third Party in respect of the Third Party License that could be deducted from royalties on relevant Net Sales otherwise owed by Salix to Progenics for such Quarter would be an amount that would reduce Progenics’s effective royalty rate for the Quarter for the relevant Product(s) to [*] percent ([*]%).

(e) Disclaimers.

Salix and its Affiliates shall maintain such records for a period of at least [*] ([*]) years after the end of the Quarter in which they were generated, provided, however, that if any records are in dispute and Salix has received notice from Progenics of the records which are in dispute, Salix shall keep such records until the dispute is resolved.

(ii) Underpayments/Overpayments. If such accounting firm concludes that additional portions of Sublicense Revenue were due to Progenics under Section 6.4(a) or additional royalties were due to Progenics under Section 6.5(a), Salix shall pay to Progenics the additional Sublicense Revenue or royalties, as the case may be, within [*] ([*]) days of the date Salix receives such accountant’s written report, plus interest, which shall be calculated at the average of the prime rate reported by JPMorgan Chase, New York City, each month during the period beginning on the day the unpaid amount was due until the unpaid amount is paid in full, plus [*] percent ([*]%) per annum. If such underpayment exceeds the greater of [*] dollars ($[*]) and [*] percent ([*]%) of the aggregate share of Sublicense Revenue and royalties that were to be paid by Salix to Progenics for the audited period, Salix also shall reimburse Progenics for the out-of-pocket expenses incurred in conducting the audit. Progenics shall not reveal to such accounting firm the conditions under which the audit expenses are to be reimbursed hereunder. If such accounting firm concludes that Salix overpaid Sublicense Revenue or royalties to Progenics, Progenics will refund such overpayments to Salix within [*] ([*]) days of the date Progenics receives such accountant’s report. [*] interest shall be due to Salix on any such overpayment.

(g) Confidentiality. All progress reports and financial information of Salix subject to review under this Article 6 shall be deemed to be Salix’s Confidential Information subject to the provisions of Article 8 hereof, and Progenics shall not disclose such Confidential Information to any Third Party or use such Confidential Information for any purpose other than reviewing progress made or verifying payments to be made by Salix to Progenics under this Agreement; provided, however, that such Confidential Information may be disclosed by Progenics to Third Parties only to the extent necessary to enforce Progenics’s rights under this Agreement.

Whenever possible, Progenics shall be given at least [*] ([*]) Business Days prior to the earlier of the expiration of any shortened statutory period for response or anticipated filing to review and comment upon the text of any such communication. Salix shall also keep Progenics advised on the maintenance of any patents included within the Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights and Ono Collaboration Joint Patent Rights and provide Progenics with reasonable opportunity to comment on maintenance.

In the event that the Parties’ respective patent counsel, after good faith discussions, cannot agree with respect to any decision to be made with respect to the preparation, filing, prosecution and maintenance of the Ono Collaboration Patent Rights (including decisions relating to interference, opposition, revocation, reexamination and similar proceedings), then Salix shall make such decision. In no event, however, shall Progenics be required to take any action that would cause Progenics to breach any Progenics Third Party Agreement or that would, in Progenics’s judgment, be contrary to law. In the event that pursuant to Section 2.12 Salix should succeed to all or substantially all of the rights and licenses currently held by Ono under the Ono Agreement, then thereafter the Ono Collaboration Patent Rights shall be deemed to constitute Progenics Patent Rights and, except as may be otherwise required by any ongoing provisions of the Ono Agreement, the prosecution and maintenance thereof shall be governed by the provisions of Section 7.2(a).

Any such notice shall include any available evidence to support an allegation of such infringement.

(b) Enforcement of Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights and Joint Patent Rights. Except as otherwise provided in this Section 7.3(b), Salix shall, as between Progenics and Salix to the extent Progenics has the right to enforce the Progenics Patent Rights, have the first right but not the obligation, at its own expense, to take action (or cause or permit to be taken action) to obtain a discontinuance of infringement or bring suit against a Third Party infringer in the Territory of any Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights. Such right shall remain in effect until [*] ([*]) days after the date of notice given under Section 7.3(a). Salix, at its own expense, may join Progenics as a party plaintiff to any action or suit resulting from Salix’s exercise of such rights. Progenics may participate, and be represented by independent counsel, in such litigation at its own expense. Salix shall not consent to the entry of any judgment or enter into any settlement with respect to such an action or suit without the prior written consent of Progenics (not to be unreasonably withheld, conditioned, or delayed) if such judgment or settlement includes a finding or agreement that any Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights are invalid, unenforceable, or not infringed, grants a Third Party license, or would enjoin or grant other equitable relief against Progenics.

Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights, as applicable, then Progenics shall have the second right, but not the obligation, at its own expense, to bring suit in Progenics’s name against such Third Party infringer in the Territory of the Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights. If Progenics exercises such second right, then Salix shall have the right but not the obligation, at its own expense, to be represented by counsel of its choice in any action or proceeding controlled by Progenics. Progenics may join Salix as a party plaintiff to any action or suit resulting from Progenics’s exercise of its second right. Progenics shall not consent to the entry of any judgment or enter into any settlement with respect to such an action or suit without the prior written consent of Salix (not to be unreasonably withheld, conditioned, or delayed) if such judgment or settlement includes a finding or agreement that any Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights are invalid, unenforceable, or not infringed, grants a Third Party license, or would enjoin or grant other equitable relief against Salix. Progenics shall bear all the expenses of any such action or suit brought by Progenics under this second right claiming infringement of any Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights, except for Salix’s expenses if Salix exercises its right to be represented by counsel of its own choice in such action or suit. Each Party shall cooperate with the other Party (including by executing any documents required to enable Salix to initiate such litigation) in any action or suit for infringement of any Progenics Patent Rights, Wyeth Collaboration Patent Rights, Wyeth Collaboration Joint Patent Rights, Ono Collaboration Joint Patent Rights or Joint Patent Rights brought by Salix against a Third Party in accordance with this Section 7.3(b) and shall have the right to consult with the other. Neither Party shall incur any liability directly to the other Party as a consequence of such action or suit or any unfavorable decision resulting therefrom, including any decision holding any Patent Right invalid or unenforceable. However, the Party exercising the right to bring an action or suit shall indemnify and hold the other Party harmless from any liability to a Third Party as a consequence of such action or suit or any unfavorable decision resulting therefrom. Any recovery obtained by either Party as a result of any such action or suit against a Third Party infringer shall be allocated first to reimburse each Party for all litigation costs in connection with such action or suit paid by that Party and then any remaining amount shall be allocated as follows:

(i) If [*] brought the infringement action or suit, any remaining portion of such recovery shall be allocated between the Parties [*] under this Agreement, as determined in good faith by the Parties; or

(ii) If [*] brought the infringement suit, [*] shall receive an amount equal to [*] percent ([*]%) of any remaining portion of such recovery and [*] shall receive the other [*] percent ([*]%).

In respect to any Progenics Patent Rights as to which Progenics does not have the right to control enforcement of such Patent Rights, Progenics (i) shall ensure that Salix is promptly provided with all such information as Progenics may receive in respect of the enforcement of such Patent Rights and with a full opportunity to participate in any consultations that may take place between Progenics and any Third Party holding the right to pursue enforcement of such Patent Rights and (ii) shall exercise such rights as it does have in respect of the enforcement of such Patent Rights in accordance with Salix’s directions.

(c) Enforcement of Ono Collaboration Patent Rights. Progenics shall exercise its rights under Section 7.2.7(c) of the Ono Agreement as directed (and only as directed) by Salix; provided, however, that any action taken by Progenics to obtain a discontinuance of infringement or bring suit against an infringer of Ono Collaboration Patent Rights pursuant to Section 7.2.7(c) shall be at Salix’s expense. Progenics shall permit any counsel that it may retain to represent it as permitted by the provisions of Section 7.2.7(c) of the Ono Agreement to be directed by Salix. Neither Party shall incur any liability directly to the other Party as a consequence of any such litigation or any unfavorable decision resulting therefrom, including any decision holding any Ono Collaboration Patent Right invalid or unenforceable. However, to the extent Salix exercises its rights under this Section 7.3(c) to direct Progenics to bring an action or suit and to direct and control the prosecution of such action or suit, Salix shall indemnify and hold Progenics harmless from any liability to a Third Party (including Ono) as a consequence of such action or suit or an unfavorable decision resulting therefrom. Any recovery allocated by Progenics under Section 7.2.7(c) of the Ono Agreement shall, in respect of any action or suit the expenses of which have been borne by Salix pursuant to this Section 7.3(c), be delivered by Progenics in its entirety to Salix. If Salix does not elect to direct Progenics’s to exercise Progenics’s rights under Section 7.2.7(c) of the Ono Agreement, then Progenics may, but is not obligated to, exercise its rights under Section 7.2.7(c) of the Ono Agreement to direct and control the prosecution of such action or suit; provided, however, that any action taken by Progenics in directing and controlling the prosecution of such action or suit to obtain a discontinuance of infringement or bring suit against an infringer of Ono Collaboration Patents pursuant to Section 7.2.7(c) shall be at Progenics’s expense. Neither Party shall incur any liability directly to the other Party as a consequence of any such litigation or any unfavorable decision resulting therefrom, including any decision holding any Ono Collaboration Patent Right invalid or unenforceable. However, to the extent Progenics exercises its rights under this Section 7.3(c) to bring an action or suit in its sole discretion and to direct and control the prosecution of such action or suit, Progenics shall indemnify and hold harmless Salix from any liability to a Third Party (including Ono) as a consequence of such action or suit or an unfavorable decision resulting therefrom. Any recovery allocated by Progenics under Section 7.2.7(c) of the Ono Agreement shall, in respect of any action or suit the expenses of which have been borne by Progenics pursuant to this Section 7.3(c), be retained by Progenics in its entirety.

Except as otherwise provided in this Section 7.3(d), Salix in the Territory and Progenics outside the Territory (the “Action Party”) shall have the first right but not the obligation, at its own expense, to take action (or cause or permit to be taken action) to obtain a discontinuance of infringement or bring suit against a Third Party infringer of any Salix Collaboration Patent Rights. Progenics shall not exercise its right outside the Territory to initiate such action (or

to cause or permit such action to be taken) without obtaining Salix’s prior written consent thereto and without providing Salix an opportunity to share jointly in the control thereof, and Progenics shall make available to Salix, upon Salix’s request, any and all documentation controlled or obtained by Progenics relating to the conduct of such an action. The right of each Party set forth in the first sentence of this Section 7.3(d) shall remain in effect until [*] ([*]) days after the date of notice given under Section 7.3(a). The Action Party may join the other Party as a party plaintiff to any action or suit resulting from the Action Party’s exercise of such rights. The Action Party shall not consent to the entry of any judgment or enter into any settlement with respect to such an action or suit without the prior written consent of the other Party (not to be unreasonably withheld, conditioned, or delayed) if such judgment or settlement includes a finding or agreement that any Salix Collaboration Patent Right is invalid, unenforceable, or not infringed, grants a Third Party license, or would enjoin or grant other equitable relief against the other Party. The Action Party shall bear all the expenses of any such action or suit brought by the Action Party claiming infringement of any Salix Collaboration Patent Rights. If, after the expiration of the [*] ([*]) day period, the Action Party has not obtained a discontinuance of the infringement of Salix Collaboration Patent Rights or filed suit against any such Third Party infringer of Salix Collaboration Patent Rights, or provided the other Party with information and arguments demonstrating to the other Party’s reasonable satisfaction that there is insufficient basis for the allegation of such infringement of Salix Collaboration Patent Rights, then the other Party shall have the right, but not the obligation, to bring an action or suit against such Third Party infringer of Salix Collaboration Patent Rights. The other Party may join the Action Party as a party plaintiff to such action or suit resulting from the other Party’s exercise of such rights. The other Party shall not consent to the entry of any judgment or enter into any settlement with respect to such an action or suit without the prior written consent of the Action Party (which consent shall not be unreasonably withheld, conditioned, or delayed) if such judgment or settlement materially impacts any of the Action Party’s rights under this Agreement or would enjoin or grant other equitable relief against the Action Party. Each Party shall cooperate (including by executing any documents required to enable the other Party to initiate such litigation) with the other Party in any action or suit for infringement of any Salix Collaboration Patent Right brought by the other Party against a Third Party in accordance with this Section 7.3(d) and shall have the right to consult with the other Party and to participate in and be represented by independent counsel in such litigation at its own expense. Neither Party shall incur any liability directly to the other Party as a consequence of such litigation or any unfavorable decision resulting therefrom, including any decision holding any Salix Collaboration Patent Right invalid or unenforceable. However, the Party exercising the right to bring an action or suit shall indemnify and hold the other Party harmless from any liability to a Third Party as a consequence of such action or suit or any unfavorable decision resulting therefrom. Any recovery obtained by either Party as a result of any such proceeding against a Third Party infringer shall be allocated first to reimburse each Party for all litigation costs in connection with such action or suit paid by that Party and then any remaining portion of such recovery shall be allocated between the Parties [*] under this Agreement, as determined in good faith by the Parties.

7.4. Infringement and Third Party Licenses.

(a) Infringement of Third Party Patents - Course of Action. If the performance of the Licensed Activities by Salix or any of its Affiliates is alleged by a Third Party to infringe a Third Party’s patent or other intellectual property right, the Party becoming aware of such allegation shall promptly notify the other Party. Additionally, if either Party determines that, based upon the review of a Third Party’s patent or patent application or other intellectual property rights, it may be desirable to obtain a license from such Third Party with respect thereto so as to avoid any potential suit between either Party and such Third Party, such Party shall promptly notify the other Party of such determination and initiate discussions to determine whether such license is desirable.

(b) Salix Option to Negotiate. Subject to Section 7.4(c), in the event that Salix determines that, in order for Salix or its Affiliates or Sublicensees to engage in the Licensed Activities, it is necessary or desirable for Salix to obtain a license under one or more patents or patent applications or other intellectual property rights owned or controlled by a Third Party (collectively, “Third Party IP Rights”), Salix shall have the first right, but not the obligation, to negotiate and enter into an agreement with such Third Party, whereby Salix is granted a license under such Third Party IP Rights permitting Salix and its Affiliates and Sublicensees, as relevant, to practice such Third Party IP Rights in connection with the Licensed Activities and the performance of any of its obligations or the exercise of any of its rights under this Agreement. If after the earlier to occur of [*] ([*]) months following Progenics’s notice to Salix of the need for a license in respect of Third Party IP Rights in order for Salix or its Affiliates or Sublicensees to engage in the Licensed Activities and [*] ([*]) days following receipt by Salix or Progenics of a written threat of imminent litigation alleging that the conduct by Salix or its Affiliates or Sublicensees of the Licensed Activities infringes Third Party IP Rights, Salix has not then entered into a license agreement with the relevant Third Party whereby Salix is granted a license under such Third Party’s Third Party IP Rights, then Progenics shall have the right, but not the obligation, to negotiate and enter into, at its expense, an agreement with such Third Party, whereby Progenics is granted a license, with the right to sublicense, under such Third Party IP Rights. Any such license into which Progenics may enter pursuant to the preceding sentence shall constitute a Progenics Third Party Agreement.

(c) Ono Third Party License. Progenics shall provide Salix with notice of any notification that it may receive from Ono pursuant to Section 7.2.8(a) of the Ono Agreement or any determination that Progenics itself may make that it may be desirable to obtain a license as contemplated by said section. Such notice shall be provided by Progenics promptly following its receipt of any such notification or its making of any such determination and in a manner appropriate to provide Salix with a reasonable opportunity to

8. CONFIDENTIALITY.

8.1. Product Information.

(a) The Progenics Parties recognize that by reason of, inter alia, Salix’s status as an exclusive licensee pursuant to the grants under Section 2.1, Salix has an interest in the Progenics Parties’ retention in confidence of certain information of the Progenics Parties. Accordingly, during the Term, the Progenics Parties shall, and shall cause their Affiliates and their respective officers, directors, employees, and agents to, keep confidential, and not publish or otherwise disclose, and not use directly or indirectly for any purpose other than to fulfill the Progenics Parties’ obligations, or exercise the Progenics Parties’ rights, hereunder or under any Subject Agreement or Related Agreement, any data or information owned or possessed by the Progenics Parties or any of their Affiliates that relates to the Compound or any Product for use in the Field, or the Manufacturing, Development or Commercialization of any of the foregoing (the “Product Information”); except to the extent (i) the Progenics Parties’ Product Information is in the public domain through no fault of the Progenics Parties or their Affiliates or any of their respective officers, directors, employees, or agents (including pursuant to disclosure as contemplated by Section 9.2(l)(i)); (ii) such disclosure or use is expressly permitted under Section 8.3, or (iii) such disclosure or use is at such time otherwise expressly permitted by the terms of this Agreement. For purposes of Section 8.3, Salix shall be deemed to be the Disclosing Party with respect to the Progenics Parties’ Product Information under Section 8.3 and the Progenics Parties shall be deemed to be the Receiving Party with respect thereto. For further clarification, (i) without limiting this Section 8.1(a), to the extent the Progenics Parties’ Product Information is disclosed by the Progenics Parties to Salix pursuant to this Agreement, such information shall, subject to the other terms and conditions of this Article 8, also constitute Confidential Information of the disclosing Progenics Party with respect to the use and disclosure of such data or information by Salix (and the Progenics Party shall be deemed to be the Disclosing Party with respect to such Product Information under Section 8.3 and Salix shall be deemed to be the Receiving Party with respect thereto), but (ii) the disclosure by a Progenics Party to Salix of the Progenics Parties’ Product Information shall not cause such information to cease to be subject to the provisions of this Section 8.1(a) with respect to the use and disclosure of such Confidential Information by the disclosing Progenics Party. In the event this Agreement is terminated, this Section 8.1(a) shall have no continuing force or effect with respect to the use or disclosure of such information, but Product Information disclosed by Salix to the Progenics Parties hereunder shall continue to be Confidential Information of Salix, subject to the terms of Sections 8.2, 8.3, and 8.5 for purposes of the surviving provisions of this Agreement.

(b) Salix recognizes that, in the event the licenses granted to Salix by Progenics are terminated pursuant to Section 10.5, the Progenics Parties will have an interest in Salix’s retention in confidence of certain information of Salix’s. Accordingly, following such termination pursuant to Section 10.5, Salix shall, and shall cause its Affiliates and their

respective officers, directors, employees, and agents to, keep confidential, and not publish or otherwise disclose, and not use directly or indirectly for any purpose other than to fulfill Salix’s obligations, or exercise Salix’s rights, hereunder any Salix Product Information (as Product Information is defined in Section 8.1(a)); except to the extent (i) the Salix Product Information is in the public domain through no fault of Salix or its Affiliates or any of their respective officers, directors, employees, or agents (including pursuant to disclosure as contemplated by Section 9.2(l)(i) mutatis mutandis); (ii) such disclosure or use is expressly permitted under Section 8.3, or (iii) such disclosure or use is at such time otherwise expressly permitted by the terms of this Agreement. For purposes of Section 8.3, following termination of the licenses from Progenics to Salix pursuant to Section 10.5, the Progenics Parties shall be deemed to be the Disclosing Party with respect to Salix’s Product Information under Section 8.3 and Salix shall be deemed to be the Receiving Party with respect thereto. For further clarification, (i) without limiting this Section 8.1(b), to the extent Salix Product Information is disclosed by Salix to the Progenics Parties pursuant to this Agreement, such information shall, subject to the other terms and conditions of this Article 8, also constitute Confidential Information of Salix with respect to the use and disclosure of such data or information by Progenics (and Salix shall be deemed to be the Disclosing Party with respect to Salix Product Information under Section 8.3 and Progenics shall be deemed to be the Receiving Party with respect thereto), but (ii) the disclosure by Salix to Progenics of Salix Product Information shall not cause such information to cease to be subject to the provisions of this Section 8.1(b) with respect to the use and disclosure of such Confidential Information by Salix.

8.2. Confidentiality. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Expanded Parties agree that, for the Term and for five (5) years thereafter, each Expanded Party (the “Receiving Party”) receiving any Confidential Information of another Expanded Party (the “Disclosing Party”) under this Agreement shall keep such Confidential Information confidential and shall not publish or otherwise disclose or use such Confidential Information for any purpose other than as provided for in this Agreement, except for Confidential Information that the Receiving Party can establish:

(i) was already known by the Receiving Party (other than under an obligation of confidentiality) at the time of disclosure by the Disclosing Party and the Receiving Party has documentary evidence to that effect; provided, however, that the foregoing exception shall not apply in respect of Regulatory Documentation and information included therein transferred to Salix pursuant to the provisions hereof or the Transition Agreement;

(ii) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the Receiving Party;

(iii) became generally available to the public or otherwise part of the public domain after its disclosure or development, as the case may be, other than through any act or omission of the Receiving Party or any of its Affiliates;

(iv) was disclosed to the Receiving Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the Disclosing Party not to disclose such information to the Receiving Party; or

(v) was independently discovered or developed by or on behalf of the Receiving Party without the use of any Confidential Information belonging to the Disclosing Party and the Receiving Party has documentary evidence to that effect; provided, however, that the foregoing exception shall not apply in respect of Regulatory Documentation and information included therein transferred to Salix pursuant to the provisions hereof or the Transition Agreement.

Information that is otherwise Confidential Information and consists of a combination of information shall not be deemed to be in the public domain if individual elements of such information are in the public domain, unless the specific combination of those elements is also in the public domain.

8.3. Authorized Disclosure.

(a) Disclosure. Notwithstanding the provisions of Sections 8.1 and 8.2, a Receiving Party may disclose Confidential Information belonging to the Disclosing Party and a Progenics Party may disclose Product Information to the extent such disclosure is reasonably necessary to:

(i) file or prosecute patent applications as contemplated by this Agreement,

(ii) prosecute or defend litigation,

(iii)(A) exercise its rights under this Agreement, including conducting clinical trials, (B) exercise its rights or perform its obligations under, in the case of Progenics, the Subject Agreements as the same exist on the date hereof, and in the case of both Salix and Progenics, the Related Agreements, provided in each such disclosure is covered by terms of confidentiality similar to those set forth herein, or (C) engage in [*], including [*] or [*], provided in each case such disclosure is covered by terms of confidentiality similar to those set forth herein, and

(iv) comply with Applicable Law.

(b) Notice of Disclosure. In the event a Receiving Party shall deem it reasonably necessary to disclose Confidential Information belonging to the Disclosing Party pursuant to this Section 8.3, the Receiving Party shall to the extent possible give reasonable advance notice of such disclosure to the Disclosing Party and take reasonable measures to ensure confidential treatment of such Confidential Information.

8.4. SEC Filings and Other Disclosures. Any Expanded Party may disclose the existence and terms of this Agreement, Product Information and other material information relating to this Agreement and the matters contemplated hereby (a) to the extent required, in the

reasonable opinion of such Expanded Party’s legal counsel, to comply with Applicable Law, including, without limitation, the rules and regulations promulgated by the United States Securities and Exchange Commission (“SEC”), and (b) in connection with a [*], provided that prior to such disclosure each such [*] shall agree in writing to be bound by obligations of confidentiality and non-use no less restrictive in scope than those set forth in this Article 8. Notwithstanding the foregoing, before making a disclosure contemplated by clause (a) above, the Expanded Parties will consult with one another on material to be redacted in making any such disclosure. If an Expanded Party makes a disclosure contemplated by clause (a) above, such Expanded Party agrees, at its own expense, to seek such confidential treatment of portions of such disclosure, as may be reasonably requested by any other Expanded Party.

(b) Press Releases. Promptly following the execution of this Agreement, the Parties shall simultaneously release their agreed-upon announcement regarding the signing of this Agreement. Thereafter, any press release or similar public announcement relating to this Agreement or the transactions and activities contemplated hereby (including relating to Development or Commercialization events in respect of Products) shall, unless otherwise agreed by the Parties, be made in the form of a joint release with form and content agreed by the Parties, provided that the foregoing shall not prohibit a Party from making any such press release or similar public announcement independently of the other Party to the extent such Party determines it must make such press release or similar public announcement in order to comply with Applicable Law and cannot in compliance with Applicable Law make such press release in the form suggested by the other Party, in which event, however, the Party proposing to make an independent press release shall use reasonable efforts to provide a draft of such press release to the other Party sufficiently in advance of release to permit the other Party to comment thereon. Except as contemplated by this Section 8.5(b) or permitted by Section 8.4, no Expanded Party shall, nor shall it permit its Affiliates to, issue any press release or similar public announcement relating to this Agreement or the transactions and activities contemplated hereby (including relating to Development or Commercialization events in respect of Products).

Each Expanded Party will each comply with standard academic practice regarding authorship of scientific publications and recognition of contribution of other persons in any publications relating to the Development or Commercialization of any Product. During the Term, each Expanded Party shall provide to the other Expanded Parties (including specifically to its in-house patent counsel) for its information any academic, scientific and medical publications relating to the Compound or any Product of which such Expanded Party is aware.

Each Progenics Party shall promptly notify Salix of any such event or of the receipt by the Progenics Party of any notice of breach or termination of the [*].

This Agreement shall take effect as of the Effective Date and, unless earlier terminated pursuant to Section 10.2, 10.3, 10.4 or 10.5, shall expire when Salix has no further obligation to make payments of Sublicense Revenues under Section 6.4 or to pay royalties under Section 6.5(a) (the “Term”).

10.2. Termination for Cause.

(a) Breach. If any of the Progenics Parties, on the one hand, or Salix, on the other hand, breaches any of its material obligations under this Agreement and has not remedied such breach within [*] ([*]) days (or, in the case of a payment breach, [*] ([*]) days) (the “Cure Period”) after receipt of notice thereof from, in the case of a breach by any Progenics Party, Salix or, in the case of a breach by Salix, the Progenics Parties (the “Notice of Breach”), then, respectively, Salix or the Progenics Parties may terminate this Agreement in its entirety but not in part immediately upon expiration of such Cure Period; provided that such Notice of Breach shall specifically identify the provisions under this Agreement that respectively, Salix or the Progenics Parties believe to have been breached and state the intent of, respectively, Salix or the Progenics Parties to terminate this Agreement upon expiration of the Cure Period. Without limiting the foregoing, the failure of either Salix or the Progenics Parties to pay any amount in excess of [*] dollars ($[*]) owed to the other within the Cure Period shall constitute a breach of a material obligation under this Agreement, provided that, if such non-payment is subject to a bona fide good faith dispute between the Expanded Parties involved in such payment as to whether such payment is due, the [*] ([*]) day Cure Period shall be tolled pending resolution of such dispute so long as the Expanded Party allegedly owing the payment in question is reasonably diligent in pursuing such resolution, and further provided that if such amount is part of a larger payment due, only the Cure Period for the amount in dispute shall be tolled.

(b) Termination by Salix Because of Serious Safety or Efficacy Reasons. If one or more safety or efficacy issues arise with respect to a Product which are sufficiently serious that Salix would cease Development or Commercialization of the Product if the Product were a product or proposed product owned solely by it, or to which it had exclusive rights, that was of similar commercial potential and at a similar stage in its development or product life, Salix shall promptly inform Progenics of such safety or efficacy issues(s) and convene a meeting of the JSC to discuss such safety or efficacy issues and their implications for Development and Commercialization of the Product. If the JSC is unable to

At any time on or after the first anniversary of the Effective Date, Salix may terminate this Agreement, in whole but not in part, for any reason or no reason, upon [*] ([*]) days’ prior notice to Progenics. Notwithstanding the foregoing, Progenics shall have a one-time right, exercisable by notice to Salix given not less than [*] ([*]) days prior to the date the Agreement would otherwise terminate, to postpone such termination for an additional [*] ([*])-day period from the date such termination would otherwise have become effective in the event that Progenics, despite its good faith and diligent efforts, has not succeeded in transitioning Development and Commercialization of the Products to Progenics or its licensee. Salix shall continue to fulfill its obligations under this Agreement during such [*] ([*]) or [*] ([*])-day period.

10.5. Termination of Licenses; Accrued Obligations.

(b) Accrued Obligations. Termination or expiration of this Agreement for any reason shall not release any Party hereto from any payment or other 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 all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this Agreement.

10.11. Bankruptcy-Related Matters. All rights and licenses granted under or pursuant to this Agreement are licenses of rights to “intellectual property” as defined in Section 365(n) of Title 11 of the United States Code (“Title 11”). Each Party agrees that the other Party, as licensee of such rights under this Agreement shall retain and may fully exercise all of its rights and elections under Title 11. Each Party agrees during the Term, to create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate embodiments, to the extent feasible, of all such intellectual property. If a case is commenced by or against a Party (the “Debtor Party”) under Title 11, the Debtor Party (in any capacity, including debtor-in-possession) and its successors and assigns (including, without limitation, a Title 11 trustee) shall:

(a) as the other Party (the “Non-Debtor Party”) may elect in a written request, immediately upon such request:

(i) perform all of the obligations provided in this Agreement to be performed by the Debtor Party including, where applicable and without limitation, providing to the Non-Debtor Party portions of such intellectual property (including embodiments thereof) held by the Debtor Party and such successors and assigns or otherwise available to them; or

(ii) provide to the Non-Debtor Party all such intellectual property (including all embodiments thereof to the extent provided by applicable non-bankruptcy law and this Agreement) held by the Debtor Party and such successors and assigns or otherwise available to them; and

(b) not interfere with the rights of the Non-Debtor Party under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of Title 11.

(c) Rights to Intellectual Property. If (i) a Title 11 case is commenced by or against the Debtor Party, (ii) this Agreement is rejected as provided in Title 11, and (iii) the Non-Debtor Party elects to retain its rights under this Agreement as provided in Title 11, then the Debtor Party (in any capacity, including debtor-in-possession) and its successors and assigns (including, without limitation, a Title 11 trustee) shall provide to the Non-Debtor Party all such intellectual property (including all embodiments thereof) held by the Debtor Party and such successors and assigns, or otherwise available to them, immediately upon the Non-Debtor Party’s written request. Whenever the Debtor Party or any of its successors or assigns provides to the Non-Debtor Party any of the intellectual property licensed under this Agreement (or any embodiment thereof to the extent provided by applicable non-bankruptcy law and this Agreement) pursuant to this Section 10.11, the Non-Debtor Party shall have the right to perform the obligations of the Debtor Party under this Agreement with respect to such intellectual property, but neither such provision nor such performance by the Non-Debtor Party shall release the Debtor Party from any such obligation or liability for failing to perform it. The Parties hereto acknowledge and agree that the milestone payments to be paid under Section 6.2 (and any other payment by Salix to Progenics under this Agreement other than the royalties to be paid under Section 6.5 and milestone payments to be paid under Section 6.3) do not constitute “royalties” within the meaning of Title 11 or relate to licenses of intellectual property under this Agreement.

(d) Additional Rights. All rights, powers and remedies of the Non-Debtor Party provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including, without limitation, Title 11) in the event of the commencement of a Title 11 case by or against the Debtor Party. The Non-Debtor Party, in addition to the rights, power and remedies expressly provided herein, shall be entitled to exercise all other such rights and powers and resort to all other such remedies as may now or hereafter exist at law or in equity (including, without limitation, Title 11) in such event. The Parties agree that they intend the foregoing rights to extend to the maximum extent permitted by law, including, without limitation, for purposes of Title 11:

(i) the right of access to any intellectual property (including all embodiments thereof) of the Debtor Party, or any Third Party with whom the Debtor Party contracts to perform an obligation of the Debtor Party under this Agreement, and, in the case of the Third Party, which is necessary for the research, Development, Manufacture and Commercialization of the Product in the Territory; and

(ii) the right to contract directly with any Third Party to complete the contracted work.

11. INDEMNIFICATION AND INSURANCE

11.1. Indemnification by Salix. Salix will indemnify, defend and hold harmless Progenics, each of its Affiliates, and each of its and its Affiliates’ employees, officers, directors and agents (each, a “Progenics Indemnified Party”) from and against any and all liability, loss, damage, expense (including reasonable attorneys’ fees and expenses) and cost (collectively, a “Liability”) that the Progenics Indemnified Party may be required to pay to one or more Third Parties resulting from or arising out of: (a) any intentional misconduct or gross negligence on the part of Salix or its Affiliates in performing any activity contemplated by this Agreement; (b) personal injury or death of any person as a result of use of any Product containing the Compound supplied or sold by Salix or its Affiliates or Sublicensees; (c) the conduct by Salix or its Affiliates or licensees or Sublicensees of any pre-clinical or clinical studies in respect of the Compound or Products; (d) liabilities assumed or incurred by Salix and its Affiliates pursuant to Section 4.6(d) and (e) in respect of Progenics Third Party Agreements assigned and delegated by Progenics or its Affiliates or licensees to Salix pursuant to such Section; or (e) the breach by Salix of any of its representations, warranties or covenants set forth in this Agreement; except, in each case ((a), (b), (c), (d) and (e)), to the extent caused by the gross negligence or intentional misconduct of Progenics or any Progenics Indemnified Party or a breach by Progenics of any of its representations, warranties or covenants set forth in this Agreement.

11.2. Indemnification by Progenics. Progenics will indemnify, defend and hold harmless Salix, its Affiliates, distributors and each of its and their respective employees, officers, directors and agents (each, a “Salix Indemnified Party”) from and against any and all Liabilities that the Salix Indemnified Party may be required to pay to one or more Third Parties resulting from or arising out of: (a) any intentional misconduct or gross negligence on the part of Progenics or its Affiliates in performing any activity contemplated by this Agreement; (b) personal injury or death of any person as a result of use of any Product containing the Compound supplied or sold by Progenics or its Affiliates or licensees or Sublicensees (other than Salix), including Product sold by Progenics or its Affiliates or licensees or Sublicensees (other than Salix) that is the subject of the Triad Recall; (c) the conduct by Progenics or its Affiliates or licensees or Sublicensees of any pre-clinical or clinical studies, including Clinical Studies identified in Schedule 9.2(p), in respect of the Compound or Products; (d) liabilities retained by Progenics and its Affiliates pursuant to Section 4.6(d) and (e), if any, in respect of Progenics Third Party Agreements assigned and delegated by Progenics or its Affiliates or licensees to Salix pursuant to such Section; or (e) the material breach by any Progenics Party of any of its representations, warranties or covenants set forth in this Agreement, provided that with respect to those contained in Section 9.2, such indemnification shall be subject to Section 9.3; except, in each case, ((a), (b), (c), (d) and (e)), to the extent caused by the gross negligence or intentional misconduct of Salix or any Salix Indemnified Party or a breach by Salix of any of its representations, warranties or covenants set forth in this Agreement.

11.3. Procedure. Each Party will notify the other Party in writing in the event it becomes aware of a Claim for which indemnification may be sought hereunder. In case any proceeding (including any governmental investigation) shall be instituted involving any Party in

respect of which indemnity may be sought pursuant to this Article 11, such Party (the “Indemnified Party”) shall promptly notify the other Party (the “Indemnifying Party”) in writing and the Indemnifying Party and Indemnified Party shall meet to discuss how to respond to any Claims that are the subject matter of such proceeding. The Indemnified Party shall cooperate fully with the Indemnifying Party in defense of such matter. The Indemnifying Party, upon request of the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such proceeding. In any such Claim, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless (a) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (b) the named parties to any such Claim (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both Parties by the same counsel would be inappropriate due to actual or potential differing interests between them. All such fees and expenses shall be reimbursed as they are incurred. The Indemnifying Party shall not be liable for any settlement of any Claim effected without its written consent, but, if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any loss or liability by reason of such settlement or judgment. The Indemnifying Party shall not, without the written consent of the Indemnified Party, effect any settlement of any pending or threatened Claim in respect of which the Indemnified Party is, or arising out of the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on Claims that are the subject matter of such proceeding.

11.4. Insurance.

(a) Progenics shall obtain and maintain, during the Term of this Agreement, commercial general liability insurance, including products liability insurance, with reputable and financially secure insurance carriers to cover its indemnification obligations under Section 11.2, in each case with limits of not less than [*] dollars ($[*]) per occurrence and in the aggregate.

(b) Simultaneously herewith, (i) the Expanded Parties are entering into a 2010 Agreement Related to Progenics’s MNTX In-License with the University of Chicago and ARCH Development Corporation; (ii) Salix and Progenics are entering into a Trademark Co-operation Agreement; and (iii) the Expanded Parties are entering into the Transition Agreement (collectively, the “Related Agreements”). The effectiveness of this Agreement is expressly conditioned on the execution and delivery of each of the Related Agreements by each of the parties thereto.

13.7. Modifications; No Waiver. No amendment, modification, release, waiver or discharge shall be binding upon the Expanded Parties unless in writing and duly executed by authorized representatives of both Parties, and shall not otherwise affect the terms and provisions of this Agreement not affected thereby, which shall remain in full force and effect. The failure of any Expanded Party hereto to enforce at any time, or for any period of time, any provision of this Agreement shall not be construed as a waiver of such provision or of the right of such Expanded Party thereafter to enforce each and every provision.

13.8. Cumulative Remedies. Except to the extent expressly stated in this Agreement, no remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under equity or law.

13.9. Assignment; Binding Effect.

(a) Without the prior written consent of the other Expanded Parties hereto, which consent shall not after it has been requested be unreasonably withheld, conditioned, or delayed, no other Expanded Party shall sell, transfer, assign, pledge or otherwise dispose of, whether voluntarily, involuntarily, by operation of law or otherwise, this Agreement or any of its rights or duties hereunder; provided, however, that any Expanded Party hereto may assign or transfer this Agreement or any of its rights or obligations hereunder without the consent of the other Expanded Parties (i) to any Affiliate of such Expanded Party; or (ii) to any Third Party with which it merges or consolidates, or to which it transfers all or substantially all of its assets relating to Products if in any such event (A) the assigning Expanded Party (provided that it is not the surviving entity) remains jointly and severally liable with the relevant Affiliate or Third Party assignee under this Agreement, and (B) the relevant Affiliate assignee, Third Party assignee or surviving entity assumes in writing all of the assigning Expanded Party’s obligations under this Agreement. For purposes of clarification, a Third Party that merges or consolidates with an Expanded Party or an Affiliate of an Expanded Party, or to which an Expanded Party or an Affiliate of an Expanded Party transfers all or substantially all of its assets to which this Agreement relates, shall not be deemed to grant the other Expanded Parties to this Agreement any license to such Third Party’s technology in existence as of the effective date of such merger, consolidation or transfer, unless such grant is made pursuant to a separate agreement, provided such Third Party shall maintain all licenses granted hereunder by such first Expanded Party with respect to its technology and any information, materials and inventions with respect thereto. Any purported assignment or transfer in violation of this Section 13.9(a) shall be void ab initio and of no force or effect.

(b) This Agreement shall be binding upon and inure to the benefit of the Expanded Parties and each of their successors and permitted assigns.

(c) Progenics may assign its rights to (i) [*], (ii) [*] described in Section [*], (iii) [*] as described in Section [*], and (iv) [*] pursuant to Section [*].

Salix shall have the right, in its sole discretion, (i) to terminate, by notice to Progenics (or its successor) given at any time within [*] ([*]) months following the closing date of any such transaction, any and all provisions contained in this Agreement (excluding Section [*]) that require Salix to [*], that Salix in its reasonable discretion [*], in each case insofar as such [*] and (ii) to disband, by notice to Progenics (or its successor) given at any time within [*] ([*]) months following the closing date of any such transaction, the Committees and terminate their activities and thereafter undertake all activities assigned by this Agreement to the Committees solely and exclusively by itself.

(b) For purposes of this Section 13.10, “control” and, with correlative meanings, the terms “controlled by” and “under common control with” means (i) the possession, directly or indirectly, of the power to direct, or cause the direction of, the management or policies, whether through the ownership of voting securities, by contract relating to voting rights or corporate governance, or otherwise, or (ii) ownership, directly or indirectly, of fifty percent (50%) or more of the shares of stock entitled to vote for the election of directors, in the case of a corporation, or fifty percent (50%) or more of the voting securities, or other voting ownership interests, in the case of any limited liability company or other type of legal entity.

13.11. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original and all of which taken together shall constitute one and the same instrument.

13.12. Executive Mediation.

(a) General. If any dispute arising out of, in connection with or relating to this Agreement occurs (a “Dispute”), including any question regarding its existence, validity or termination, but, subject to Section 3.5(c), excluding any dispute relating to a matter within the jurisdiction of the JSC, any Expanded Party may, by notice to the other Expanded Parties party to such Dispute, have such Dispute referred to their respective officer designated below for attempted resolution by good faith negotiations within [*] ([*]) days after such notice is received (“Executive Mediation”). Such negotiations shall not be admissible in any subsequent dispute resolution proceeding. Said designated officers are: (a) for the Progenics Parties: [*], and (b) for Salix: [*]. If the designated officers are unable to resolve the dispute, then any Expanded Party may seek to resolve the dispute pursuant to litigation in accordance with Section 13.17. The Expanded Parties shall continue performing their obligations under the Agreement in accordance with its provisions pending the outcome of Executive Mediation under this Section 13.12.

(b) Interim Relief. Notwithstanding anything herein to the contrary, nothing in this Section 13.12 shall preclude any Expanded Party from seeking interim or provisional relief, including a temporary restraining order, preliminary injunction or other interim equitable relief concerning a Dispute, if necessary to protect the interests of such Expanded Party. This Section 13.12 shall be specifically enforceable.

*	Confidential treatment requested; certain information omitted and filed separately with the SEC.

13.13. No Consequential Damages. IN NO EVENT SHALL ANY EXPANDED PARTY OR ITS AFFILIATES BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER LEGAL THEORY; provided that this limitation shall not limit the indemnification obligations of either Party under Article 11 for damages claimed by a Third Party that are indemnifiable thereunder; and provided further that this Section 13.13 shall not apply with respect to any breach by any Expanded Party of the obligations of confidentiality and non-use set forth in Article 8.

All references in this Agreement to an Article, Section, or Schedule shall refer to an Article, Section, or Schedule in or to this Agreement, unless otherwise stated. The word “including” and similar words shall mean “including without limitation” and “including, but not limited to,”.

13.15. Representation by Counsel. The Expanded Parties acknowledge and agree that: (i) each Expanded Party and its counsel reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision, (ii) the rule of construction to the effect that any ambiguities are resolved against the drafting party shall not be employed in the interpretation of this Agreement, and (iii) the terms and provisions of this Agreement shall be construed fairly as to all Expanded Parties hereto and not in a favor of or against any Expanded Party, regardless of which Expanded Party was generally responsible for the preparation of this Agreement.

13.18. Specific Enforcement. The Expanded Parties acknowledge and agree that, without restriction, the restrictions set forth in Article 8 are reasonable and necessary to protect the legitimate interests of the other Expanded Parties and that such other Expanded Parties would not have entered into this Agreement in the absence of such restrictions, and that any breach or threatened breach of any such provision or other prohibitive or mandatory provision of this Agreement may result in irreparable injury to such other Expanded Parties for which there will be no adequate remedy at law. In the event of a breach or threatened breach of any such provision, the non-breaching Expanded Parties shall be authorized and entitled to obtain from any court of competent jurisdiction injunctive relief, whether preliminary or permanent, specific performance and an equitable accounting of all earnings, profits and other benefits arising from such breach, which rights shall be cumulative and in addition to any other rights or remedies to which such non-breaching Expanded Parties may be entitled in law or equity.

(a) Each Expanded Party shall have the right to subcontract any of its Development and Commercialization activities with respect to Products to one or more Third Party contractors, provided that it furnishes the other Expanded Parties with advance notice thereof and an opportunity to consult regarding such subcontract, which notice shall specify the work to be subcontracted, and obtains a written undertaking from the Third Party contractor that it shall be subject to the applicable terms and conditions of this Agreement, including the provisions of Article 8.

(f) Certain Representations and Warranties. ProNev hereby represents, warrants, and covenants to Salix as follows:
