Development) and Article 5 (with respect to the regulatory aspects of Development), the Parties have already agreed that certain Development activities for the Product in the Field, up to and including the Effective Date, pursuant to the Original Agreement, were to be jointly funded and others were to be solely funded by Allos. The Parties have also agreed upon a mechanism for proposing new studies in the Field and determining whether the Parties wish to jointly fund such studies or if one of the Parties may conduct such study without funding from the other Party.

4.2 Development Plan.

(a) General. Development of the Product with respect to the Field shall be conducted pursuant to a comprehensive written development plan (the “Development Plan”), which shall specify all Development activities for the Product in the Field by Mundipharma, regardless of whether such activities are jointly funded by the Parties or funded by just one of the Parties, and shall include a detailed timeline for performing those activities necessary to obtain Regulatory Approval in the Field in each country in the Licensed Territory (such timeline, the “Regulatory Plan”). For each Development activity specified in the Development Plan, the Development Plan shall specify the timeline for initiating and completing such activity, and the budget for such activity. For each clinical trial specified in the Development Plan, the Development Plan shall specify the planned accrual for such trial, the sites at which the trial will be conducted and the lead investigator(s) for such trial. For clarity, the Initial Development Plan and the Amended Development Plan shall each be considered iterations of the Development Plan, it being understood that neither party shall be obligated to perform trials and/or studies set forth in the Initial Development Plan that are not included in the Amended Development Plan or the Allos Required Studies Schedule.

(b) Initial Development Plan; Amended Development Plan. The Parties agreed upon an initial development plan, which was set forth in the Letter Agreement (the “Initial Development Plan”). The studies set forth in Exhibit 1 to the Initial Development Plan, as amended from time to time (the “Existing Studies”) included: (i) studies that were being conducted by or on behalf of Allos as of the Original Effective Date; (ii) activities that had not been initiated as of the Original Effective Date but were needed to generate Information that was required by the FDA as a condition of the Product’s Regulatory Approval in the U.S. for the Lead Indication; (iii) certain medical affairs, and clinical and non-clinical studies that were identified in Exhibit 1 to the Initial Development Plan, as amended from time to time, as “Allos Studies”; and (iv) those pediatric studies (and associated preclinical and CMC requirements) required by the EMA with respect to the Product in the Field (the “Pediatric Studies”). The Initial Development Plan identified the Party with operational responsibility for the activities that formed a part of the Existing Studies. Each Party shall be responsible for such Party’s share (i.e., the Allos Share or the Mundipharma Share, as applicable) of the costs associated with the Existing Studies incurred before the Transition Date, pursuant to the Original Agreement, except that Allos shall be solely responsible for all costs incurred before the Transition Date, pursuant to the Original Agreement, with respect to the conduct of all Allos Studies. After the Transition Date, (i) no Development activities for the Product in the Field will be jointly funded (except for an Additional Study pursuant to Section 4.4(b)), (ii) the cost of the Existing Studies (including any Existing Study relating to First Line PTCL Indications) will be solely funded by Allos, (iii) any Development activities for the Product in the Field in the Licensed Territory conducted by Mundipharma will be solely funded by Mundipharma (except for an Additional Study pursuant to Section 4.4(b)), and (iv) any Incremental Studies pursuant to Section 4.4(c) shall be borne by the Party conducting such study. For clarity, after the Transition Date, (i) neither Party shall have any Joint Development Cost payment obligations to the other Party, except as set forth in Section 7.2, and (ii) each Party, in addition to the Development activities

24

referenced in subsection (iii) of this Section 4.2(b), shall continue to rely on its right of access to data pursuant to Section 4.8, and right of reference to Regulatory Materials pursuant to Section 5.4, for the purpose of Developing and Commercializing the Product in the Field in such Party’s territory. In connection with this amendment and restatement of the Original Agreement, the Parties have agreed upon an amended Development Plan, which is set forth in the Second Letter Agreement (the “Amended Development Plan”).

(c) Amendments. The JPC shall periodically review and approve, and, as required or requested by Mundipharma, prepare an amendment to the then-current Development Plan. Such amended Development Plan shall reflect any changes (including additions) to the Development of the Product in the Field by Mundipharma. Once approved by the JPC, the amended Development Plan shall become effective and supersede the previous Development Plan as of the date of such approval. Promptly after the Parties agree to conduct an Additional Study proposed by Mundipharma pursuant to Section 4.4(b), or Mundipharma decides to proceed with an Incremental Study pursuant to Section 4.4(c), the JPC shall prepare, review and approve an amendment to the Development Plan that adds such Additional Study or Incremental Study to the Development Plan.

(d) Performance. Each Party shall use Reasonably Diligent Efforts to conduct the Development activities allocated to such Party in the Development Plan or the Allos Required Studies Schedule, as applicable, in a timely and effective manner. Each Party shall conduct its activities under the Development Plan or the Allos Required Studies Schedule, as applicable, in a good scientific manner and comply in all material respects with all applicable Laws.

4.3 Omitted.

4.4 Future Development Activities.

(a) Proposed Study. If either Party wishes to conduct and/or fund any additional Development activities in the Field (including company-sponsored studies to explore the utility of the Product in the Field and/or to expand the label of the Product in such Party’s territory to include additional Indications and also including testing one or more New Forms) that are not already set forth in the Development Plan or the Allos Required Studies Schedule (each of the foregoing activities, a “Proposed Study”), the proposing Party shall present to the other Party’s representatives on the JPC the proposed design and timeline for such Proposed Study and the proposed budget for such Proposed Study. The JPC shall discuss such Proposed Study at its next meeting, whether regularly scheduled or specially requested under Section 3.1(c), and the proposing Party shall provide, within [***] after such JPC meeting (or such longer period of time as agreed upon in writing by the Parties), any additional information reasonably requested by the other Party’s JPC representatives prior to or during such JPC meeting.

(b) Additional Study. If within [***] after the JPC meeting at which a particular Proposed Study is discussed (or such longer period of time as agreed upon in writing by the Parties) (i) the other Party notifies the proposing Party in writing that the other Party wishes to cooperate in such Proposed Study, and any Related Studies contemplated at such time, on the terms (including design, budget and timeline) proposed by the proposing Party or (ii) the Parties agree in writing upon the terms (including design, budget, timeline and rights and obligations upon wind-down or

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

25

termination) under which they will cooperate in such Proposed Study, then it will be deemed an “Additional Study.” If such Additional Study is proposed by Mundipharma, the Development Plan shall be amended pursuant to Section 4.2(c) to include such Additional Study. The Parties shall have the diligence obligations with respect to such Additional Study as provided in Section 4.2(d). The Parties shall share all Joint Development Costs incurred to conduct such Additional Study in accordance with the applicable budget and in the proportions mutually agreed by the Parties. All Information resulting from such Additional Study will be available for use by each Party with respect to the Development and Commercialization of the Product in the Field in its respective territory in accordance with the licenses and rights granted or retained under Article 2 of this Agreement.

(c) Incremental Studies.

(i) If all information reasonably requested by the non-proposing Party has been provided by the proposing Party and by the [***] after the JPC meeting at which a particular Proposed Study is discussed (or such longer period of time as agreed upon in writing by the Parties) under Section 4.4(b): (x) (1) the other Party has not notified the proposing Party in writing that the other Party wishes to cooperate in such Proposed Study on the terms (including design, budget and timeline) proposed by the proposing Party, or (2) the Parties have not agreed in writing upon the terms (including design, budget and timeline) under which they will cooperate in such Proposed Study, and (y) if Mundipharma is the proposing Party, Allos has not notified Mundipharma that it believes that such Proposed Study is substantially likely to create a Material Impact, then such Proposed Study will be deemed an “Incremental Study”, the proposing Party shall be deemed the “Conducting Party” with respect to such Incremental Study, the other Party shall be deemed the “Non-Conducting Party” with respect to such Incremental Study and, unless the Conducting Party notifies the JPC that it does not wish to proceed with such Incremental Study, (A) if Mundipharma is the Conducting Party, the Development Plan shall be amended pursuant to Section 4.2(c) to include an Incremental Study and to specify Mundipharma as solely responsible for the conduct and costs of such Incremental Study, and (B) if Allos is the Conducting Party, Allos shall be solely responsible for the conduct and costs of such Incremental Study. The Non-Conducting Party shall not be responsible for any costs, including milestones, unless such Non-Conducting Party opts-in to such Incremental Study pursuant to Section 4.4(c)(v). Mundipharma as the Conducting Party may proceed with an Incremental Study only after an amendment to the Development Plan. If Allos believes that a Proposed Study is substantially likely to create a Material Impact and Mundipharma disputes whether such belief is reasonable, the JPC shall discuss and decide whether such belief is reasonable. The Proposed Study shall be deemed an Incremental Study if the JPC decides that Allos’ belief is not reasonable. If the JPC agrees that Allos’ belief is reasonable, then Mundipharma shall not proceed with the Proposed Study. If the JPC cannot agree whether Allos’ belief is reasonable, then such dispute shall be handled in accordance with Section 13.2.

(ii) Notwithstanding each Party’s exclusive commercial rights to its respective territory, Mundipharma shall have the right to conduct an Incremental Study in patients in the Allos Territory (subject to Section 4.4(c)(i) above), and Allos shall have the right to conduct an Incremental Study in patients in the Licensed Territory.

26

(iii) The Conducting Party shall promptly inform the JPC of any material changes it wishes to make to an Incremental Study, including the budget therefor, and, if Mundipharma is the Conducting Party, the Development Plan shall be amended to address them unless, Allos believes that the amendment is substantially likely to have a Material Impact, in which case the JPC shall review such amendment and approve it only if the JPC decides that Allos’ belief is not reasonable. If the JPC agrees that Allos’ belief is reasonable, Mundipharma shall proceed without such material changes. If the JPC cannot agree whether Allos’ belief is reasonable, then such dispute shall be handled in accordance with Section 13.2. The Conducting Party may suspend or terminate an Incremental Study without obtaining approval from the JPC if there is a Safety Reason or such suspension or termination is required by a Regulatory Authority or investigational review board; provided, the Conducting Party shall promptly notify the JPC of any such suspension or termination.

(iv) Promptly following the availability of interim data from or completion of an Incremental Study, the Conducting Party shall deliver to the JPC the top-line data summary from such Incremental Study. The Non-Conducting Party will have no rights to use any Information resulting from such Incremental Study in any filings with Regulatory Authorities, for Commercialization in its territory, or otherwise, provided, however, that the Non-Conducting Party may file required safety information with the applicable Regulatory Authorities in its territory in accordance with Section 4.8(b) and refer to the Regulatory Materials in accordance with Section 5.4.

(v) Opt-In.

(A) Within [***] of the Conducting Party having obtained final results in an Incremental Study establishing Clinical Proof of Concept, such Conducting Party shall deliver to the Non-Conducting Party the top-line data summary from such Incremental Study (the delivery date of such top-line data summary, the “Opt-In Option Date”), and the Non-Conducting Party with respect to such Incremental Study shall have the right (the “Opt-In Right”) to convert such Incremental Study to an Additional Study by (1) making a payment to the Conducting Party of a mutually agreeable amount as Non-Conducting Party’s share of the development costs already incurred by the Conducting Party (which amount shall take into account the cost incurred by the Conducting Party to perform such Incremental Study and an appropriate premium to be paid by the Non-Conducting Party to exercise such Opt-In Right) (such payment, the “Opt-In Payment”), and (2) agreeing with the Conducting Party upon the budget, timeline, rights and obligations upon wind-down or termination and allocation of operational responsibility for Development activities, if any, to be performed with respect to such Incremental Study and all Related Studies after the exercise of such Opt-In Right and committing to pay its mutually agreed share of Joint Development Costs incurred with respect to such Incremental Study and Related Studies after the exercise of such Opt-In Right.

(B) If the Non-Conducting Party with respect to such Incremental Study is considering exercising its Opt-In Right with respect to such Incremental Study, it shall, no later than [***] after the Opt-In Option Date, notify the Conducting Party in writing and shall request that the Conducting Party provide: (1) an estimate for the Opt-In Payment (the “Opt-In Estimate”), which estimate shall be based upon the development costs already incurred by the Conducting Party with respect to such Incremental Study together with those anticipated to be incurred by the Conducting Party (as contemplated by Section 4.4(c)(v)(A)(1)), within [***] after the date of such notice (in each case, calculated as described in Section 4.4(c)(v)(A)(1)); and (2) a proposal to convert

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

27

an Incremental Study to an Additional Study, which amendment shall address the items specified in Section 4.4(c)(v)(A)(2), to the extent applicable to such Incremental Study. The Conducting Party shall provide such estimate and proposal, together with reasonable documentation of the Conducting Party’s already incurred costs, within [***] after such notice (or such longer period of time as agreed upon in writing by the Parties). The Conducting Party shall promptly answer all reasonable questions posed by, and provide all additional documents reasonably requested by, the Non-Conducting Party with respect to the Opt-In Estimate. The JPC shall discuss such proposed conversion at its next meeting, whether regularly scheduled or specifically requested under Section 3.1(c). The Conducting Party shall provide, within [***] after such JPC meeting (or such longer period of time as agreed upon in writing by the Parties), any additional information reasonably requested by the Non-Conducting Party’s JPC representatives prior to or during such JPC meeting. The Non-Conducting Party shall be deemed to have exercised its Opt-In Right with respect to such Incremental Study if, within [***] after the JPC meeting at which such proposed amendment to the Development Plan is discussed (or such longer period of time as agreed upon in writing by the Parties), the Conducting Party receives payment of the Opt-In Estimate amount and the JPC reviews and approves the proposal to convert such Incremental Study to an Additional Study, which proposal addresses the items specified in Section 4.4(c)(v)(A)(2), to the extent applicable to such Incremental Study.

(C) Upon exercise of the Opt-In Right with respect to a particular study, such study shall cease to be an Incremental Study and shall be deemed to be an Additional Study, the Parties shall share all future Joint Development Costs associated therewith as mutually agreed and the Parties shall have the diligence obligations with respect to such Additional Study as provided in Section 4.2(d).

(d) Related Studies. The agreement by the Parties to any Additional Study under this Section 4.4, whether from the outset of the study pursuant to Section 4.4(a) or (b), or through either Party’s exercise of its Opt-In Right to an Incremental Study pursuant to Section 4.4(c)(v), shall not be deemed an agreement by the Parties to cooperate in any and all related studies necessary for the implementation of such Additional Study or to obtain Drug Approval in the U.S. and all Major Market Countries in the applicable new Indication or new formulation that is the subject of such Additional Study (excluding any related studies that are required exclusively to obtain Drug Approval in the U.S. and not in any Major Market Country) (each such related study, a “Related Study”). Upon the agreement by the Parties to any Additional Study under this Section 4.4, the Parties shall use good faith efforts to discuss and agree on the terms (including design, budget, timeline and rights and obligations upon wind-down or termination) under which they will cooperate in any Related Studies that may be necessary. If, after discussion, the Parties cannot agree on the terms (including design, budget, timeline and rights and obligations upon wind-down or termination) under which they will cooperate in such Related Study, (i) the conducting Party may conduct the Related Study and shall be solely responsible for such conduct and the costs of such Related Study, and (ii) the terms of Section 4.4 shall apply to any such Related Study as if such Related Study is an Incremental Study. If the Parties agree on the terms of any Related Study, the terms of Section 4.4 shall apply to any Related Study in the same manner that they apply to the Additional Study to which such Related Study relates.

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

28

(e) Manufacture. With respect to any Additional Study or Incremental Study (for which either Party is the Conducting Party) that involves a New Form, the Conducting Party shall offer the Non-Conducting Party the opportunity to be the supplier of such New Form. Unless the Non-Conducting Party informs the Conducting Party that it is not interested in being, or is unable to be, the supplier of such New Form, the Parties shall negotiate in good faith and enter into a separate supply agreement that sets forth the terms and conditions under which the Non-Conducting Party will supply such New Form to the Conducting Party (in the event of an Incremental Study) or one or both Parties (in the event of an Additional Study). If the Non-Conducting Party informs the Conducting Party that it is not interested in being, or is unable to be, the supplier of such New Form, then the Non-Conducting Party shall grant to the Conducting Party a non-exclusive, royalty-free limited right and license, under the Allos Manufacturing Know-How and Allos Patents, or Mundipharma Know-How, Mundipharma-Controlled manufacturing-related Information and Mundipharma Patents, as applicable, to manufacture such New Form, with (in the event Mundipharma is the Conducting Party) the right to sublicense in accordance with Section 2.1(f) to its Affiliates or, with the prior written consent of the Non-Conducting Party, to a Third Party manufacturer (which consent shall not be unreasonably withheld, conditioned or delayed), solely for use in accordance with this Agreement.

4.5 Development Costs. The Parties shall each be responsible for their respective share (i.e., the Allos Share or the Mundipharma Share, as applicable) of all Joint Development Costs incurred up to and including the Transition Date pursuant to the Original Agreement. After the Effective Date, the Parties shall share all Joint Development Costs incurred to conduct an Additional Study in the proportions mutually agreed by the Parties. Allos shall also be responsible for all costs and expenses of the Allos Studies. The Party conducting an Incremental Study shall be solely responsible for all costs and expenses of such Incremental Study, unless the other Party exercises its Opt-In Right with respect to such study in accordance with Section 4.4(c)(v).

4.6 Diligence. Mundipharma and Allos shall each use Reasonably Diligent Efforts to Develop the Product in each country in the Licensed Territory in accordance with their respective activities under the Development Plan and the Allos Required Studies Schedule, respectively; provided, that Mundipharma shall comply with the Development milestones in Japan (the “Japan Milestones”) set forth in the Amended Development Plan.

4.7 Investigator Sponsored Studies.

(a) Before either Party authorizes or facilitates an investigator to conduct an ISS for the Product in the Field, such Party shall notify the other Party in writing, which notice shall provide a reasonably detailed description of such ISS and shall provide the other Party a reasonable opportunity to review and comment upon such ISS. Such Party shall give reasonable consideration to the other Party’s comments.

(b) If Mundipharma proposes to authorize or facilitate an investigator to conduct an ISS for the Product in the Field, Allos shall have [***] after the notice required under Section 4.7(a) is given (or such longer period of time as agreed upon in writing by the Parties) to allege that the conduct of such ISS is substantially likely to create a Material Impact and if Mundipharma disagrees with such allegation, then the JPC shall discuss and decide whether such

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

29

belief is reasonable. Mundipharma may proceed with the proposed ISS, if the JPC decides that Allos’ belief is not reasonable. If the JPC agrees that Allos’ belief is reasonable, then Mundipharma shall not proceed with the ISS. If the JPC cannot agree whether Allos’ belief is reasonable, then such dispute shall be handled in accordance with Section 13.2.

(c) ISSs shall not be included in the Development Plan or the Allos Required Studies Schedule.

(d) A Party authorizing or facilitating an ISS pursuant to this Section 4.7 shall only receive disclosure, access or a license to any Information or Patent arising from such ISS under terms that allow such Party to Control such Information or Patent, such that such Information or Patent shall be included in Allos ISS Technology if such Party is Allos or Mundipharma ISS Technology if such Party is Mundipharma. Such Party shall disclose all such Information and Patents to the other Party promptly following its receipt of disclosure of or access to such Information or Patent.

4.8 Data Exchange and Use. Upon the Effective Date, Allos shall provide Mundipharma with access, free of charge, to all Allos Know-How then in existence that constitutes pre-clinical or clinical data relating to the Product. For clarity, Allos does not have any obligation to disclose or provide access to any Information with respect to manufacture of the Product except in the event the license under Section 2.1(c) becomes effective and then only in accordance with Section 2.1(c) and the Supply Agreement. In addition to its adverse event and safety data reporting obligations pursuant to Section 5.7, each Party shall promptly provide the other Party with access to, at no additional charge:

(a) all safety, clinical and other development Information (including, if requested, raw data) associated with the conduct of the Shared Studies, as reasonably necessary or useful to support such other Party’s Development or Commercialization of the Product in the Field in accordance with this Agreement, including rights of access and reference to Regulatory Materials; and

(b) all safety Information (including, if requested, raw data) generated pursuant to any Incremental Study which the Non-Conducting Party is required by a Regulatory Authority in its territory to file with such Regulatory Authority to support safety disclosure requirements. The Non-Conducting Party shall have no rights to use any other Information arising from such Incremental Study in any filings with Regulatory Authorities in its territory (i.e., in the Allos Territory where Allos is the Non-Conducting Party and in the Licensed Territory where Mundipharma is the Non-Conducting Party) unless and until such Non-Conducting Party exercises its right, pursuant to Section 4.4(c)(v), to convert such Incremental Study to an Additional Study.

4.9 Development Reports. Each Party shall provide the JPC with written reports detailing its Development activities under this Agreement and the results of such activities at least [***] in advance of each regularly scheduled JPC meeting; provided, subject to Section 4.4(c)(iv), such reports will not include the results of any Incremental Studies for which the other Party has not exercised its Opt-In Right and made the payments required to be made under Section 4.4. The Parties shall discuss the status, progress and results of each Party’s Development activities under this Agreement at such regularly scheduled JPC meetings.

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

4.10 Development Records. Each Party shall maintain complete, current and accurate records of all Development activities conducted by it hereunder, and all data and other Information resulting from such activities. Such records shall fully and properly reflect all work done and results achieved in the performance of the Development activities in good scientific manner appropriate for regulatory and patent purposes. Each Party shall document all non-clinical studies and clinical trials in formal written study records according to applicable Laws, including applicable national and international guidelines such as ICH, GCP and GLP. Each Party shall have the right to review and copy such records maintained by the other Party at reasonable times, and upon reasonable notice, to obtain access to the original records to the extent such Party has a license to use the Information contained in such records.

4.11 Compliance with Laws. Each Party shall conduct its activities under this Agreement in a good scientific manner and comply in all material respects with all applicable Laws, including applicable national and international guidelines such as ICH, GCP and GLP.

4.12 Allos’ Other Licensees. For clarity, if Allos grants a Third Party an exclusive license to Develop and/or Commercialize a Product in any country in the Allos Territory, then such licensee may directly exercise Allos’ rights pursuant to this Agreement with respect to such Product in such country; provided, that a licensee in a Transferred Country shall not have the right to enforce any provision of this Agreement against Mundipharma.

ARTICLE 5

REGULATORY MATTERS

5.1 Regulatory Responsibilities in the Licensed Territory.

(a) Omitted.

(b) Commencing on the Original Effective Date with respect to all countries of the Licensed Territory, Mundipharma shall use Reasonably Diligent Efforts in respect of the Product as the primary interface with and shall otherwise handle all correspondence, meetings and other interactions with the relevant Regulatory Authorities concerning regulatory activities related to the Product in the Field in the Licensed Territory, and Mundipharma shall be responsible for preparing and filing any and all Regulatory Materials for the Product in the Field in the Licensed Territory at its sole expense. Allos shall assist and cooperate at its own expense with Mundipharma in connection with the preparation and filing of such Regulatory Materials, as reasonably requested by Mundipharma, including preparation of ongoing clinical trials, study reports and Periodic Safety Update Reports (“PSURs”). Such cooperation will include promptly responding within procedural timelines set by Regulatory Authorities to any reasonable request from Mundipharma for Allos Know-How needed for the Regulatory Materials. For clarity, Allos shall not be obligated to provide Mundipharma with any Information that is not Allos Know-How.

Mundipharma shall have a period of ninety (90) days after its receipt or delivery of notice under Section 8.4(a) to elect to so enforce the Joint Patents, Allos Patents or Mundipharma Patents against such Licensed Territory Infringement (or to settle or otherwise secure the abatement of such Licensed Territory Infringement). If Mundipharma fails to commence a suit to enforce the applicable Joint Patents, Allos Patents or Mundipharma Patents against such Licensed Territory Infringement or to settle or otherwise secure the abatement of such Licensed Territory Infringement within such period, then Allos shall have the right, but not the obligation, to commence a suit or take action to enforce such Joint Patents, Allos Patents or Mundipharma Patents against such Licensed Territory Infringement at its own cost and expense. In this case, Mundipharma shall take appropriate actions in order to enable Allos to commence a suit or take the actions set forth in the preceding sentence.

In this case, Allos shall take appropriate actions in order to enable Mundipharma to commence a suit or take the actions set forth in the preceding sentence. If neither Allos nor Mundipharma commences a suit or takes action to enforce the PDX Patents, the PDX Licensor may elect to take such enforcement action.

8.6 PDX Patents. Each Party’s rights under this Article 8 with respect to the prosecution, maintenance and enforcement of any PDX Patent shall be subject to the rights of the PDX Licensor to prosecute, maintain and enforce such PDX Patent. Notwithstanding the foregoing, Allos shall provide Mundipharma reasonable opportunity to review and comment on prosecution efforts regarding the PDX Patents to the extent the PDX Licensor consults with Allos and provides Allos the right to review and comment on the same, in each case as is required pursuant to section 8.2 of the PDX License Agreement.

8.7 Infringement of Third Party Rights in the Licensed Territory. Subject to Article 10, if a Product used or sold by Mundipharma, its Affiliates or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent granted by a jurisdiction within the Licensed Territory (each such claim or assertion a “Third Party Claim”), Mundipharma shall promptly notify Allos and the Parties shall agree on and enter into a common interest agreement, pursuant to which the Parties will agree to work toward their shared, mutual interest in the outcome of such potential dispute, and thereafter, the Parties shall promptly meet to consider the Third Party Claim and the appropriate course of action. Mundipharma shall be solely responsible for the defense of any such Third Party Claim, at Mundipharma’s cost and expense; provided that the provisions of Section 8.4 shall govern the right of Mundipharma to assert a counterclaim of infringement of any Allos Patents, Joint Patents or Mundipharma Patents.

51

8.8 Patent Marking. Mundipharma and its Affiliates and Sublicensees shall mark any Product marketed and sold by Mundipharma or its Affiliates or Sublicensee hereunder with appropriate patent numbers or indicia; provided, however, that Mundipharma shall only be required to so mark such Product to the extent such markings or such notices would affect recoveries of damages or equitable remedies available under applicable Laws with respect to infringement of Patents in the Licensed Territory.

The Parties shall coordinate use of the [***] trademark in their respective Commercialization activities between the Allos Territory and the Licensed Territory as part of their territorial coordination pursuant to Section 6.8.

The foregoing indemnity obligation shall not apply (i) to the extent that (x) the Allos Indemnitees fail to comply with the indemnification procedures set forth in Section 10.4 and Mundipharma’s defense of the relevant Claims is prejudiced by such failure or (y) such Claims arise out of or result from the gross negligence or willful misconduct of Allos or its Affiliates, or any related breach by Allos of its representations, warranties and/or covenants hereunder; or (ii) to Claims for which Allos has an obligation to indemnify Mundipharma pursuant to Section 10.1, as to which Claims each Party shall indemnify the other to the extent of its respective liability for such Claims.

10.3 Shared Claims. Notwithstanding the foregoing, any Claims brought against either Party that directly or indirectly arise out of, are based on, or result from, the performance of any (i) Shared Study (other than an Allos Study) in accordance with the Development Plan (including the Initial Development Plan), or (ii) an Allos-Facilitated ISS or Mundipharma-Facilitated ISS, and that (in the case of both (i) and (ii)) are not otherwise subject to indemnity under Sections 10.1 or 10.2 (“Shared Claims”) shall be shared by the Parties; provided, that for the purposes of this Section 10.3 only, “Shared Study” means (i) up to and including the Effective Date, any of the Existing Studies (other than an Allos Study) or Additional Studies, and (ii) after the Effective Date, Additional Studies. For clarity, any Claims brought against either Party that directly or indirectly arise out of, are based on, or result from the performance of any Existing Study after the Effective Date shall be subject to Allos’ indemnity under Section 10.1 and any Claim that is brought after the Effective Date but arises out of, is based on, or results from the conduct of any Existing Study prior to the Effective Date shall be a Shared Claim. Any and all damages, losses, liabilities, costs, expenses (including court costs and reasonable attorneys’ fees and expenses) and recoveries paid to a Third Party or incurred by the Parties in connection with Shared Claims (“Shared Costs”) shall be equally shared and paid for by the Parties, and each Party shall reimburse the other as required to give effect to this Section 10.3. The Parties shall confer through the JPC how to respond to Shared Claims and how to handle Shared Claims in an efficient manner (including which Party will have the right to assume the defense of Shared Claims). In the absence of such an agreement, each Party shall have the right to take such action with respect to Shared Claims as it deems appropriate. Notwithstanding the foregoing, the obligations set forth in this Section 10.3 shall not apply to the extent a Shared Claim arises out of or results from the gross negligence or willful misconduct of a Party or such Party’s Affiliates, or any related breach by such Party of its representations, warranties and/or covenants hereunder.

10.4 Indemnification Procedures. The Party claiming indemnity under this Article 10 (the “Indemnified Party”) shall give written notice to the Party from whom indemnity is being sought (the “Indemnifying Party”) promptly after learning of such Claim. The Indemnified Party shall provide the Indemnifying Party with reasonable assistance, at the Indemnifying Party’s expense, in connection with the defense of the Claim for which indemnity is being sought. The Indemnified Party may participate in and monitor such defense with counsel of its own choosing at its sole expense; provided, however, the Indemnifying Party shall have the right to assume and conduct the defense of the Claim with counsel of its choice. The Indemnifying Party shall not settle any Claim without the prior written consent of the Indemnified Party, not to be unreasonably withheld, unless the settlement involves only the payment of money. So long as the Indemnifying Party is actively defending the Claim in good faith, the Indemnified Party shall not settle or compromise any such Claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the Claim as provided above, (a) the Indemnified Party may defend against, consent to the entry of any judgment, or enter into any

64

settlement with respect to such Claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (b) the Indemnifying Party shall remain responsible to indemnify the Indemnified Party as provided in this Article 10.

10.5 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 10.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 10.1 OR 10.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN ARTICLE 11.

10.6 Insurance. Each Party shall procure and maintain insurance, including product liability insurance, or shall self-insure, in each case in a manner adequate to cover its obligations hereunder and consistent with normal business practices of prudent companies similarly situated at all times during which any Product is being clinically tested or commercially distributed or sold by such Party. Each Party shall procure insurance or self-insure at its own expense, except for clinical trial insurance specifically obtained for any Shared Study, the costs of which shall be shared as mutually agreed by the Parties. It is understood that such insurance shall not be construed to create a limit of either Party’s liability with respect to its indemnification obligations under this Article 10. Each Party shall provide the other Party with written evidence of such insurance or self-insurance upon request. Each Party shall provide the other Party with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance.

ARTICLE 11

CONFIDENTIALITY

11.1 Confidentiality. Each Party agrees that, during the Term and for a period of five (5) years thereafter, it and its Affiliates shall keep confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as provided for in this Agreement or the Supply Agreement (which includes the exercise of any rights or the performance of any obligations hereunder or thereunder) any Confidential Information furnished to it or its Affiliate by the other Party or its Affiliate pursuant to this Agreement or the Supply Agreement, except to the extent expressly authorized by this Agreement or the Supply Agreement or as otherwise agreed to in writing by the Parties. The foregoing confidentiality and non-use obligations shall not apply to any portion of the other Party’s Confidential Information that the receiving Party can demonstrate by competent written proof:

(a) was already known to the receiving Party or its Affiliate, other than under an obligation of confidentiality, at the time of disclosure by the other Party or its Affiliate;

(b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party or its Affiliate;

65

(c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party or its Affiliate in breach of this Agreement;

(d) was disclosed to the receiving Party or its Affiliate by a Third Party who had a legal right to make such disclosure and who did not obtain such information directly or indirectly from the other Party or its Affiliate; or

(e) was independently discovered or developed by the receiving Party or its Affiliate without access to or aid, application or use of the other Party’s Confidential Information, as evidenced by a contemporaneous writing.

11.2 Authorized Disclosure. Notwithstanding the obligations set forth in Section 11.1, a Party or its Affiliate may disclose the other Party’s Confidential Information and the terms of this Agreement to the extent:

(a) such disclosure is reasonably necessary (i) for the filing or prosecuting of Patent rights as contemplated by this Agreement or the Supply Agreement; (ii) to comply with the requirements of Regulatory Authorities with respect to obtaining and maintaining Regulatory Approval of the Product; or (iii) for prosecuting or defending litigation as contemplated by this Agreement or the Supply Agreement;

(b) such disclosure is reasonably necessary to its officers, directors, employees, agents, consultants, contractors, licensees, sublicensees, attorneys, accountants, lenders, insurers or licensors on a need-to-know basis for the sole purpose of performing its obligations or exercising its rights under this Agreement or the Supply Agreement; provided that in each case, the disclosees are bound by obligations of confidentiality and non-use no less stringent than those contained in this Agreement;

(c) such disclosure is reasonably necessary to any bona fide potential or actual investor, acquiror, merger partner, or other financial or commercial partner for the sole purpose of evaluating an actual or potential investment, acquisition or other business relationship; provided that in each case, the disclosees are bound by written obligations of confidentiality and non-use having a minimum term of five (5) years; or

(d) such disclosure is reasonably necessary to comply with applicable Laws, including regulations promulgated by applicable security exchanges, court order, administrative subpoena or other order.

Notwithstanding the foregoing, in the event a Party or its Affiliate is required to make a disclosure of the other Party’s Confidential Information pursuant to Section 11.2(a) or 11.2(d), such Party shall promptly notify the other Party of such required disclosure and, upon the other Party’s request, such Party and its Affiliates shall use reasonable efforts to obtain, or to assist the other Party in obtaining, a protective order preventing or limiting the required disclosure.

11.3 Technical Publication. All publications, and other forms of public disclosure such as abstracts and presentations, of results of studies carried out under this Agreement or otherwise relating to the Product (each of the foregoing, a “Publication”) shall comply with the strategy established by the JPC pursuant to Section 3.1(a)(i). Neither Party nor their Affiliates may submit

66

for publication, publish or present a Publication without the opportunity for prior review by the other Party, except to the extent required by applicable Laws. A Party seeking, or whose Affiliate is seeking, to submit, publish or present a Publication shall provide the other Party the opportunity to review and comment on the proposed Publication at least fifteen (15) days prior to its intended submission for publication or presentation. The other Party shall provide the Party seeking, or whose Affiliate is seeking, to publish or present with its comments in writing, if any, within ten (10) days after receipt of such proposed Publication. The Party seeking, or whose Affiliate is seeking, to publish or present shall consider in good faith any comments thereto provided by the other Party and shall comply with the other Party’s request to remove any and all of such other Party’s Confidential Information from the proposed Publication; provided, however, that Information arising from a Shared Study shall not be considered the other Party’s Confidential Information for purposes of this Section 11.3. In addition, the Party seeking, or whose Affiliate is seeking, to publish or present shall delay the submission for a period of up to thirty (30) days in the event that the other Party can demonstrate reasonable need for such delay in order to prepare and file a patent application for which it has prosecution control pursuant to this Agreement. If the other Party fails to provide its comments to the Party seeking, or whose Affiliate is seeking, to publish or present within such ten (10)-day period, such other Party shall be deemed not to have any comments, and the Party seeking, or whose Affiliate is seeking, to publish or present shall be free to submit for publication or present in accordance with this Section 11.3 after the fifteen (15)-day period has elapsed. The Party seeking, or whose Affiliate is seeking, to publish or present shall provide the other Party a copy of the manuscript, abstract or presentation at the time of the submission or presentation, as applicable. Each Party agrees to acknowledge the contributions of the other Party and its Affiliates and their employees in all publications, as scientifically appropriate.

(a) The Parties agree that the material terms of this Agreement are the Confidential Information of both Parties, subject to the special authorized disclosure provisions set forth in this Section 11.4.

(b) Omitted.

(c) If either Party or its Affiliate desires to make a public announcement concerning the material terms of this Agreement, or any clinical or regulatory announcements, such Party shall give reasonable prior advance notice of the proposed text of such announcement to the other Party for its prior review and approval (except as otherwise provided herein), such approval not to be unreasonably withheld. A Party commenting on such a proposed announcement shall provide its comments, if any, within five (5) business days after receiving the announcement for review, or such shorter period as may be reasonably required in order for the proposing Party to comply with any applicable deadline for making such announcement (as such deadline is communicated by the proposing Party to the commenting Party). In addition, where required by applicable Laws, including regulations promulgated by applicable security exchanges, such Party or its Affiliate shall have the right to make a press release announcing the achievement of each milestone under this Agreement as it is achieved, the achievements of Regulatory Approvals in the Licensed Territory as they occur, or any other material event with respect to this Agreement or the Parties’ performance thereof, subject only to the review procedure set forth in the preceding sentence; provided that the review period shall be reduced to two (2) business days (or such shorter period as may be reasonably required in order for the proposing Party to comply with any applicable deadline for making such press release, as such deadline is communicated by the proposing Party to the commenting Party) if

67

the deadline for making such disclosure is five (5) or fewer business days after such achievement or event. In relation to the other Party’s review of such an announcement, such other Party may make specific, reasonable comments on such proposed press release within the prescribed time for commentary, but shall not withhold its consent to disclosure of the information that the relevant milestone or Regulatory Approval has been achieved or material event has occurred. Neither Party nor their Affiliates shall be required to seek the permission of the other Party to repeat any information regarding the terms of this Agreement that has already been publicly disclosed by such Party or its Affiliate, or by the other Party or its Affiliate, in accordance with this Section 11.4, provided such information remains accurate as of such time.

(d) The Parties acknowledge that either or both Parties may be obligated to file under applicable Laws a copy of this Agreement with the U.S. Securities and Exchange Commission (“SEC”) or other Governmental Authorities. Each Party shall be entitled to make such a required filing, provided that it requests confidential treatment of the commercial terms and sensitive technical terms hereof and thereof to the extent such confidential treatment is reasonably available to such Party. In the event of any such filing, each Party will provide the other Party with a copy of this Agreement marked to show provisions for which such Party intends to seek confidential treatment and shall reasonably consider and incorporate the other Party’s comments thereon to the extent consistent with the legal requirements, with respect to the filing Party, governing disclosure of material agreements and material information that must be publicly filed.

11.5 Prior Confidentiality Agreements. The First Confidentiality Agreement and the Second Confidentiality Agreement remain in full force and effect and are not superseded by this Agreement. All Information disclosed by a Party or its Affiliate to the other Party or its Affiliate pursuant to the First Confidentiality Agreement or the Second Confidentiality Agreement shall be deemed to be such Party’s Confidential Information disclosed hereunder and the other Party and its Affiliates and disclosees shall have the confidentiality, non-use and non-disclosure obligations set forth in this Article 11. In the event that any such obligations conflict with the obligations set forth in the First Confidentiality Agreement or the Second Confidentiality Agreement, then the other Party and its Affiliates and disclosees shall comply with the obligations set forth in this Article 11.

11.6 Return of Confidential Information. Except as otherwise set forth in this Agreement, upon termination of this Agreement, the receiving Party will promptly return all of the disclosing Party’s Confidential Information, including all reproductions and copies thereof in any medium, except that the receiving Party may retain one copy for its legal files.

11.7 Unauthorized Use. If either Party becomes aware or has Knowledge of any unauthorized use or disclosure of the other Party’s Confidential Information, it will promptly notify the other Party of such unauthorized use or disclosure.

11.8 Exclusive Property. All Confidential Information is the sole and exclusive property of the disclosing Party and the permitted use thereof by the receiving Party for purposes of its performance hereunder will not be deemed a license or other right of the receiving Party to use any such Confidential Information for any other purpose.

ARTICLE 12

12.1 Term. This Agreement shall become effective on the Effective Date and, unless earlier terminated pursuant to this Article 12, shall remain in effect on a country-by-country basis until the expiration of the Royalty Term for the Product in such country (the “Term”). Upon the expiration of the Royalty Term for a Product in a particular country, the licenses granted by Allos to Mundipharma under Sections 2.1(a) and 2.1(b) in such country shall become fully-paid and royalty free and, except for the sublicenses granted thereunder to the Allos Technology licensed to Allos under the PDX License Agreement, such licenses shall remain exclusive. Upon the expiration of the Royalty Term for a Product in a particular country pursuant to Section 7.4(b)(i) or Section 7.4(b)(iii), the sublicenses granted under Sections 2.1(a) and 2.1(b) to the Allos Technology licensed to Allos under the PDX License Agreement in such country shall become non-exclusive.

12.2 Termination for Breach. Each Party (the “Non-Breaching Party”) shall have the right to terminate this Agreement in its entirety or on a country-by-country basis immediately upon written notice to the other Party (the “Breaching Party”) if the Breaching Party materially breaches its obligations under this Agreement and, after receiving written notice identifying such material breach in reasonable detail (a “Default Notice”), fails to cure such material breach within [***] after delivery of the Default Notice (or within [***] after delivery of the Default Notice in the event such material breach is solely based on the Breaching Party’s failure to pay any amounts due hereunder). For the avoidance of doubt, in addition to any other failure to pay any amounts due hereunder, failure by either Party to pay any portion of its Joint Development Costs under this Agreement shall constitute a material breach of such non-paying Party’s obligations under this Agreement.

12.3 Termination for Patent Challenge. Mundipharma will provide written notice to Allos at least [***] prior to Mundipharma or its Affiliates or Sublicensees (individually or in association with any other person or entity) bringing an action to challenge the validity, enforceability or scope of any Allos Patents or Joint Patents anywhere in the world. In the event that Mundipharma or its Affiliates or Sublicensees (individually or in association with any other person or entity) brings an action to challenge the validity, enforceability or scope of any Allos Patents or Joint Patents anywhere in the world, Allos shall have the right to terminate this Agreement in its entirety immediately upon written notice to Mundipharma.

(a) Termination Upon Written Notice. Notwithstanding any other provision of this Agreement, Mundipharma may terminate this Agreement in its entirety upon ninety (90) days prior written notice to Allos at any time.

(b) Termination by Regulatory Authority. Should any serious and unexpected events or issues occur with respect to the safety of any Product as a result of which (i) Regulatory Approval for such Product is terminated or suspended in one or more regulatory jurisdictions in the Licensed Territory, or (ii) a Regulatory Authority directs or requests discontinuance of development, use or sale of such Product in one or more countries in the Licensed Territory, then Mundipharma’s

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

69

obligations under this Agreement with respect to such Product will be suspended in such regulatory jurisdiction(s) and/or country(ies) (as applicable) until such serious safety event is resolved and Regulatory Approval for such Product is no longer terminated or suspended or the Regulatory Authority has given approval again to distribute or sell such Product (as applicable) in such regulatory jurisdiction(s) and/or country(ies). Mundipharma may, upon written notice to Allos, terminate this Agreement pursuant to this Section 12.4(b) if Mundipharma’s obligations under this Agreement are suspended pursuant to this Section 12.4(b) for a period in excess of twelve (12) months.

(c) Breach or Termination of PDX License Agreement.

(i) Within [***] of receiving written notice from the PDX Licensor that Allos is in material breach of the PDX License Agreement (a “PDX Breach”), Allos shall provide Mundipharma with written notice of such PDX Breach. To the extent that Allos is unable or unwilling to cure the PDX Breach within the applicable cure period, and provided that Allos does not dispute the PDX Breach within the applicable cure period, the Parties hereby agree that Mundipharma shall have the right, but not the obligation, to cure such PDX Breach (or cause such PDX Breach to be cured) on behalf of Allos. To the extent that Allos disputes the PDX Breach, Mundipharma will not proceed to cure or cause such PDX Breach to be cured in accordance with this Section 12.4(c)(i) unless and until Allos is unsuccessful in defending against such PDX Breach. In the event Mundipharma proceeds to cure or causes such PDX Breach to be cured on behalf of Allos in accordance with this Section 12.4(c)(i), any payments owed by Mundipharma to Allos under this Agreement shall immediately be reduced by the amount so expended by Mundipharma to cure such PDX Breach (or cause such PDX Breach to be cured) on behalf of Allos.

(ii) Notwithstanding the provisions of Section 12.4(c)(i), Mundipharma may terminate this Agreement immediately on written notice to Allos in the event that the PDX License Agreement terminates for any reason unless Mundipharma has consented in writing to such termination.

(d) Omitted.

12.4A Unilateral Termination by Allos. Notwithstanding any other provision of this Agreement, Allos shall have the right to terminate this Agreement solely with respect to the territory of Japan immediately upon written notice to Mundipharma if (i) Mundipharma fails to achieve a Japan Milestone, and (ii) after receiving written notice identifying such failure to meet a Japan Milestone (a “Japan Milestone Default Notice”), Mundipharma fails to thereafter meet such Japan Milestone within a revised period of time, to be agreed as follows:

(e) If, within [***] after delivery of the Japan Milestone Default Notice, Mundipharma fails to meet a Japan Milestone, the matter shall be submitted to the JPC for its review, and the JPC shall determine a revised timetable for Mundipharma to achieve such Japan Milestone.

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

70

(f) If the JPC is unable to agree on a revised timetable for Mundipharma’s achievement of such Japan Milestone within [***] after such matter is submitted to the JPC, then an Expert shall determine such revised timetable for Mundipharma’s achievement of such Japan Milestone as follows:

(i) Upon the written request of either Party, the Parties shall promptly negotiate in good faith to appoint an appropriate Expert who shall have such scientific, technical, regulatory and commercial experience as is necessary to resolve such dispute and who shall not be or have been during the preceding five (5) years an Affiliate, employee, consultant, officer or director of either Party or any of their respective Affiliates. If the Parties are not able to agree upon an Expert within [***] after the receipt by a Party of the written request in the immediately preceding sentence, each Party shall select one (1) Expert within [***] thereafter, and those two (2) Experts shall select a third Expert within [***] thereafter and such third Expert (selected by the first two Experts) shall be the designated Expert for resolution of the dispute. The fees and costs of the Expert shall be borne [***].

(ii) Within [***] after the designation of the Expert, the Parties shall each submit to the Expert and to one another a written statement of their respective positions on the reason for Mundipharma’s failure to achieve such Japan Milestone and the appropriate revised timetable for Mundipharma’s achievement of such Japan Milestone. Each Party shall have [***] from receipt of the other Party’s submission to submit a written response thereto, which shall include any scientific, commercial and technical information in support thereof. The Expert shall have the right to meet with the Parties, either alone or together, as necessary to make a determination.

(iii) No later than [***] after the designation of the Expert, the Expert shall make a determination by selecting the revised timetable for Mundipharma’s achievement of such Japan Milestone of one of the Parties that as a whole is the most fair and reasonable to the Parties in light of the totality of the circumstances resulting in Mundipharma’s failure to achieve such Japan Milestone (such circumstances as may include actions taken by any Regulatory Authorities in Japan as it relates to Mundipharma’s achievement of such Japan Milestone, and any correspondence, meetings and other interactions between Mundipharma and such Regulatory Authorities in Japan (as the same shall be disclosed to the Expert and Allos together with Mundipharma’s written statement in support of its position)), and the Expert shall provide the Parties with a written statement setting forth the basis of the determination in connection therewith. The Expert shall not have authority to render any substantive decision other than to select the position proposed by Allos or Mundipharma. The determination of the Expert shall be final and conclusive.

12.5 Termination for Bankruptcy. Each Party shall have the right to terminate this Agreement in its entirety immediately upon written notice to the other Party if the other Party (i) applies for or consents to the appointment of, or the taking of possession by, a receiver, custodian, trustee or liquidator of itself or of all or a substantial part of its property, (ii) makes a general assignment for the benefit of its creditors, (iii) commences a voluntary case under the Bankruptcy Code, (iv) files a petition seeking to take advantage of any applicable Laws relating to bankruptcy, insolvency, reorganization, winding-up, or composition or readjustment of debts, (v) has a proceeding or case commenced against it in any court of competent jurisdiction (which proceeding or case is not discharged within sixty (60) days of the filing thereof), seeking (A) its liquidation, reorganization, dissolution or winding-up, or the composition or readjustment of its debts, (B) the

(i) Regulatory Materials; Data; Domain Names. To the extent permitted by applicable Laws, Mundipharma shall transfer and assign to Allos: (A) all Regulatory Materials, Regulatory Approvals, and related data relating to the Product throughout the Licensed Territory, or solely with respect to the territory of Japan, as applicable, except for Incremental Studies where Mundipharma is the Conducting Party and Allos has not exercised its Opt-In Right pursuant to Section 4.4(c)(v), and (B) all domain names registered by Mundipharma in accordance with Section 8.9(d), and, in connection with the preceding, Mundipharma shall cooperate as reasonably requested by Allos to effect such transfer on the applicable domain name registries.

(ii) Mundipharma License. Mundipharma hereby grants to Allos, effective upon such termination, a non-exclusive, fully paid, royalty-free, irrevocable license (with the right to grant sublicenses through multiple tiers), under the Mundipharma Technology, to Develop, make, have made, use, sell, offer for sale, import and otherwise Commercialize the Products throughout the Licensed Territory, or solely with respect to the territory of Japan, as applicable.

(iii) Transition Assistance.

To the extent that any such contract between Mundipharma and a Third Party is not assignable to Allos, Mundipharma shall reasonably cooperate with Allos to arrange to continue to provide such services for a reasonable time after termination.

(iv) Omitted.

72

(v) Inventories. Allos shall have the right to purchase from Mundipharma any and all of the inventory of Product held by Mundipharma as of the date of termination at a price equal to the transfer price paid by Mundipharma to Allos for such inventory. Allos shall notify Mundipharma within [***] after the date of termination whether Allos elects to exercise such right. Until Allos exercises such right, or if Allos does not exercise such right within such [***] period, then Mundipharma shall be entitled to continue selling such remaining inventory of Product subject to a continuing obligation to pay royalties pursuant to Section 7.4(a) on Net Sales arising from such sales.

(vi) Mundipharma Sublicense Agreements. Allos shall have the option, at its sole discretion, to (a) assume Mundipharma’s rights and obligations under any Mundipharma Sublicense Agreement, or (b) terminate the Mundipharma Sublicense Agreement in its entirety.

(i) Transfer to Mundipharma. All of Mundipharma’s rights under Section 2.1 of this Agreement shall continue, and Mundipharma shall require that Allos promptly takes, and Allos hereby agrees to take, such actions as Mundipharma may reasonably request, in order to transfer to Mundipharma or its Affiliates or Sublicensees, free of charge, in respect of the Licensed Territory only, all of the rights, title and interest retained by Allos pursuant to Section 2.1(e). In the event of such an assignment, Allos will, at its expense and at Mundipharma’s request, deliver, execute and/or deliver or cause to be delivered, all such assignments, consents, documents or further instruments of transfer or license, and take or cause to be taken all such actions as may be reasonably necessary to effectuate such transfer. Allos will further reconvey and release to Mundipharma all rights and privileges originally granted to Allos by Mundipharma under this Agreement (including those granted under Section 8.9), including those co-exclusive rights, such that all such rights and privileges will vest exclusively with Mundipharma. Mundipharma will, in such circumstances not be required to pay any further milestones required under Section 7.3 of this Agreement, but shall pay to Allos the royalties on all Net Sales of Products in the Licensed Territory set forth in Section 7.4, after deducting (A) royalty payments made to the PDX Licensor (with respect to the same Net Sales) in accordance with Mundipharma’s assumption of the rights and responsibilities of the PDX License Agreement pursuant to Section 12.6(b)(iii); and (B) [***] of Mundipharma’s costs (if any) of curing the consequences of Allos’ breach or actions that resulted in termination under Section 12.4(c)(ii).

Mundipharma will thereafter be free to exercise its rights to all Product in the Licensed Territory, as reconveyed and released pursuant to this Section 12.6(b)(i) in the Licensed Territory as it may see fit, and Allos will not take any actions or make any omissions to prevent Mundipharma therefrom;

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

73

(ii) Transition Assistance. Allos shall provide such reasonable assistance, at no cost to Mundipharma, as may be reasonably necessary or useful for Mundipharma to continue Developing the Product throughout the Licensed Territory to the extent Allos is then performing or having performed such activities, including assigning or amending as appropriate, upon request of Mundipharma, any agreements or arrangements with Third Party vendors to Develop the Product. To the extent that any such contract between Allos and a Third Party is not assignable to Mundipharma, Allos shall reasonably cooperate with Mundipharma to arrange to continue to provide such services for a reasonable time after termination; and

(iii) Assumption of PDX License Agreement. Provided that Mundipharma is not in breach of this Agreement at the time the PDX License Agreement terminates, in exercising its rights under Section 12.6(b)(y), Mundipharma will assume all rights and responsibilities of Allos under the PDX License Agreement, including the royalties, milestones and sublicense fees provisions [***], to the extent applicable to the rights granted to Mundipharma under this Agreement (i.e., in respect of the Licensed Territory only).

(c) Upon the early termination of this Agreement by Mundipharma pursuant to Section 12.4(d), Mundipharma may choose, in its sole discretion, (x) to take those actions and permit Allos to exercise those rights set forth in Section 12.6(a)(i), (iii), (v) and (vi), or (y) have any or all of the following apply and, in the event that Mundipharma elects to have the following apply, the following shall be Mundipharma’s sole and exclusive remedy for or relating to Mundipharma’s termination of this Agreement pursuant to Section 12.4(d):

(i) Transfer to Mundipharma. All of Mundipharma’s rights under Section 2.1 of this Agreement shall continue, and Mundipharma shall require that Allos promptly takes, and Allos hereby agrees to take, such actions as Mundipharma may reasonably request, in order to transfer to Mundipharma or its Affiliates or Sublicensees, free of charge, in respect of the Licensed Territory only, all of the rights, title and interest retained by Allos pursuant to Section 2.1(e), excluding the rights, title and interest of Allos under the PDX License Agreement unless, and only to the extent, the PDX Licensor consents to the assignment of such rights, title and interest (and assumption of the obligations) under the PDX License Agreement in respect of the Licensed Territory. In the event of such an assignment, Allos will, at its expense and at Mundipharma’s request, deliver, execute and/or deliver or cause to be delivered, all such assignments, consents, documents or further instruments of transfer or license, and take or cause to be taken all such actions as may be reasonably necessary to effectuate such transfer (excluding any transfer of the rights, title and interest of Allos under the PDX License Agreement unless, and only to the extent, the PDX Licensor consents to the transfer of such rights, title and interest (and assumption of the obligations) under the PDX License Agreement in respect of the Licensed Territory). Allos will further reconvey and release to Mundipharma all rights and privileges originally granted to Allos by Mundipharma under this Agreement (including those granted under Section 8.9), including those co-exclusive rights, such that all such rights and privileges will vest exclusively with Mundipharma; provided, however, Mundipharma hereby grants to Allos, effective upon termination under Section 12.4(d), a non-exclusive, fully paid, royalty-free limited right and license under any Patent Controlled by Mundipharma that claims the Product or the API or the manufacture or use in the Field

of the Product or the API to Develop, make, have made, use, sell, offer for sale, import and otherwise Commercialize the Products throughout the Allos Territory. Mundipharma will, in such circumstances not be required to pay any further milestones required under Section 7.3 of this Agreement, but shall pay to Allos the royalties on all Net Sales of Products in the Licensed Territory set forth in Section 7.4, after deducting (A) royalty payments made to the PDX Licensor (with respect to the same Net Sales) in accordance with Mundipharma’s assumption of the rights and responsibilities of the PDX License Agreement pursuant to Section 12.6(c)(iii) and (B) [***] of Mundipharma’s costs (if any) of curing the consequences of Allos’ breach or actions that resulted in termination. Such other provisions hereof as are necessary to administer the calculation and payment of such royalties will also survive such termination, including any audit, payment and record retention provisions. Mundipharma will thereafter be free to exercise its rights to all Product in the Licensed Territory, as reconveyed and released pursuant to this Section 12.6(c)(i) in the Licensed Territory as it may see fit, and Allos will not take any actions or make any omissions to prevent Mundipharma therefrom;

(ii) Transition Assistance. Allos shall provide such reasonable assistance, at no cost to Mundipharma, as may be reasonably necessary or useful for Mundipharma to continue Developing the Product throughout the Licensed Territory to the extent Allos is then performing or having performed such activities, including assigning or amending as appropriate, upon request of Mundipharma, any agreements or arrangements with Third Party vendors to Develop the Product.To the extent that any such contract between Allos and a Third Party is not assignable to Mundipharma, Allos shall reasonably cooperate with Mundipharma to arrange to continue to provide such services for a reasonable time after termination; and

(iii) Assumption of PDX License Agreement. Provided that Mundipharma is not in breach of this Agreement on the effective date of termination of this Agreement pursuant to Section 12.4(d), in exercising its rights under Section 12.6(c)(y), Mundipharma will assume all rights and responsibilities of Allos under the PDX License Agreement, including the royalties, milestones and sublicense fees provisions [***], to the extent applicable to the rights granted to Mundipharma under this Agreement (i.e., in respect of the Licensed Territory only).

12.7 Survival. Termination or expiration of this Agreement shall not affect rights or obligations of the Parties under this Agreement that have accrued prior to the date of termination or expiration. Notwithstanding anything to the contrary, the following provisions shall survive any expiration or termination of this Agreement: (i) Articles 1 (to the extent defined terms are contained in the following surviving Articles and Sections), 10, 11 (other than Section 11.3) and 13 (other than Section 13.2); (ii) Sections 2.4, 4.10 (for a period of five (5) years after such expiration or termination), 7.2, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 7.10 (provided that the preceding Sections of Article 7 shall survive only with respect to any payment incurred or accrued prior to such expiration or termination), 8.1, 8.9(l), 9.5, 12.6, 12.7, 14.1, 14.3, 14.4, 14.7, 14.8, 14.9, 14.11 and 14.15; and (iii) solely with respect to Joint Patents, Sections 8.3, 8.4 and 8.5.

ARTICLE 13

DISPUTE RESOLUTION

13.1 Arbitration. In the event of any disputes, controversies or differences which may arise between the Parties (except for disputes arising from the JPC, which shall be handled pursuant to Section 13.2 and only handled pursuant to this Section 13.1 as provided in Section 13.2), out of or in relation to or in connection with this Agreement, including any alleged failure to perform, or breach, of this Agreement, or any issue relating to the interpretation or application of this Agreement, then upon the request of either Party, the Parties agree to meet and discuss in good faith a possible resolution thereof, which good faith efforts shall include at least one in-person meeting between the Executive Officers of each Party. If the matter is not resolved within [***] following the request for discussions, either Party may then invoke arbitration under this Section 13.1. Any dispute, controversy or claim arising out of or relating to the validity, construction, interpretation, enforceability, breach, performance, application or termination of this Agreement that is not resolved pursuant to Section 13.2 or by the Parties meeting in good faith to resolve such dispute, controversy or claim as outlined above, except for a dispute, claim or controversy under Section 13.5, shall be settled by binding arbitration administered by JAMS pursuant to its Comprehensive Arbitration Rules and Procedures then in effect (the “JAMS Rules”), except as otherwise provided herein. The arbitration will be conducted in New York, New York and the Parties consent to the personal and subject matter jurisdiction of the state and federal courts in New York, New York, for any case arising out of or otherwise related to this arbitration, its conduct and its enforcement. Any situation not expressly covered by this Agreement shall be decided in accordance with the JAMS Rules.

13.2 Referred from JPC. With respect to disputes arising from matters delegated or referred to the JPC pursuant to the terms of this Agreement, either Party may, by written notice to the other Party, have such dispute referred to each Party’s Executive Officers for attempted resolution by good faith negotiations within [***] after such notice is received. If the Executive Officers of the Parties are not able to resolve a dispute within the [***] period described above, then the Executive Officer of Allos or Mundipharma, as the case may be, shall have the unilateral right to cast the deciding vote for the JPC as provided in Section 13.2(a) or 13.2(b). If neither Party has the right to cast the deciding vote for the JPC pursuant to Section 13.2(a) or 13.2(b) (e.g., where Section 13.2(a) or 13.2(b) provides for exceptions to the Executive Officer’s right to make the final decision), then either Party may submit the dispute for resolution pursuant to Section 13.1.

(a) Allos Decisions. The Executive Officer of Allos shall have the right to make the final decision with respect to: (i) any decision regarding Development of the Product for the Field in the Allos Territory or an Incremental Study being conducted by Allos; (ii) any decision regarding Commercialization of the Product in the Field in the Allos Territory; or (iii) all Development studies (clinical and pre-clinical) where Allos reasonably believes either that the studies pose a substantial and unwarranted safety risk (a “Safety Reason”) or that such decision is substantially likely to cause a Material Impact (in accordance with Section 4.4(c)). Nothing in this Section 13.2(a) shall be construed to limit Allos’ (A) ability to carry out day-to-day decisions related to its Development activities as set forth in the Allos Required Studies Schedule, (B) compliance with applicable Laws or reporting requirements to Regulatory Authorities, or (C) sole discretion with respect to pricing decisions with respect to the Product in the Allos Territory.

[***]: CONFIDENTIAL PORTIONS OMITTED AND FILED SEPARATELY WITH THE COMMISSION.

76

(b) Mundipharma Decisions. The Executive Officer of Mundipharma shall have the right to make the final decision with respect to: (i) any decision regarding Development of the Product for the Field in the Licensed Territory (except for a decision involving an Additional Study or a decision described in Section 13.2(a)(ii)) or an Incremental Study being conducted by Mundipharma, except where Allos reasonably believes either that there is a Safety Reason or that such decision is substantially likely to cause a Material Impact; or (ii) any decision regarding Commercialization of the Product in the Field in the Licensed Territory. Nothing in this Section 13.2(b) shall be construed to limit Mundipharma’s (A) ability to carry out day-to-day decisions related to its Development activities as set forth in the Development Plan, (B) compliance with applicable Laws or reporting requirements to Regulatory Authorities, or (C) sole discretion with respect to pricing decisions with respect to the Product in the Field in the Licensed Territory.

13.3 Equitable Relief. Notwithstanding Sections 13.1 and 13.2, each Party acknowledges that its breach of Article 11 may cause irreparable harm to the other Party, which cannot be reasonably or adequately compensated by damages in an action at law. By reason thereof, each Party agrees that the other Party shall be entitled, in addition to any other remedies it may have under this Agreement or otherwise, to seek preliminary and permanent injunctive and other equitable relief from any state or federal court of competent jurisdiction in New York, New York to prevent or curtail any actual or threatened breach of Article 11 that is reasonably likely to cause it irreparable harm. In addition, notwithstanding Sections 13.1 and 13.2, to the fullest extent provided by Law, either Party may bring an action in any court of competent jurisdiction for injunctive relief (or any other provisional remedy) to protect a Party’s rights or enforce a Party’s obligations under this Agreement pending final resolution of any claims related thereto pursuant to the dispute resolution procedure set forth in Section 13.1.

13.4 Governing Law. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be governed by and construed under the laws of the State of New York, without giving effect to any choice of law principles that would require the application of the laws of a different state.

13.5 Patent and Trademark Disputes. Notwithstanding Section 13.1, any dispute, controversy or claim relating to the scope, validity, enforceability or infringement of any Patent or trademark rights outside the U.S. covering the manufacture, use, importation, offer for sale or sale of the Product shall be submitted to a court of competent jurisdiction in the country in which such Patent or trademark rights were granted or arose.

ARTICLE 14

MISCELLANEOUS

14.1 Entire Agreement; Amendment. This Agreement amends and restates in full the Original Agreement. This Agreement, including the Exhibits and Schedules hereto, together with the Amended Development Plan, the Allos Required Studies Schedule, the Supply Agreement, the Consent, the Letter Agreement, the Second Letter Agreement, the Pharmacovigilance Agreements, as amended, and the Technical Agreement, as amended, sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions and understandings between the Parties hereto with respect to the subject matter hereof and supersedes, as of the Effective Date, all prior and contemporaneous agreements and understandings between the Parties with respect to the subject matter hereof. There are no covenants, promises, agreements,

77

warranties, representations, conditions or understandings, either oral or written, between the Parties with respect to the subject matter of this Agreement other than as are set forth in this Agreement, the Amended Development Plan, the Allos Required Studies Schedule, the Supply Agreement, the Pharmacovigilance Agreement and the Technical Agreement. No subsequent alteration, amendment, change or addition to this Agreement shall be binding upon the Parties unless reduced to writing and signed by an authorized officer of each Party.

14.2 Force Majeure. Both Parties shall be excused from the performance of their obligations under this Agreement to the extent that such performance is prevented by force majeure and the non-performing Party promptly provides notice of the prevention to the other Party. Such excuse shall continue for so long as the condition constituting force majeure continues and the non-performing Party takes reasonable efforts to remove the condition. For purposes of this Agreement, force majeure shall include conditions beyond the control of the Parties, including an act of God, war, civil commotion, terrorist act, epidemic, failure or default of public utilities or common carriers, destruction of production facilities or materials by fire, earthquake, storm or like catastrophe, and failure of plant or machinery (provided that such failure could not have been prevented by the exercise of skill, diligence, and prudence that would be reasonably and ordinarily expected from a skilled and experienced person engaged in the same type of undertaking under the same or similar circumstances). Notwithstanding the foregoing, a Party shall not be excused from making payments owed hereunder because of a force majeure affecting such Party. If a force majeure persists for more than ninety (90) days, then the Parties will discuss in good faith the modification of the Parties’ obligations under this Agreement in order to mitigate the delays caused by such force majeure.

14.3 Notices.

14.5 Assignment. Neither Party may assign or transfer this Agreement or any rights or obligations hereunder without the prior written consent of the other Party, except that a Party may make such an assignment without the other Party’s consent to its Affiliates or to a Third Party successor to substantially all of the business of such Party to which this Agreement relates (such Third Party, an “Acquiror”), whether in a merger, sale of stock, sale of assets or other transaction. Any successor or assignee of rights and/or obligations permitted hereunder shall, in writing to the other Party, expressly assume performance of such rights and/or obligations. The Allos Technology, in the case of Allos as assignor or transferor, or the Mundipharma Technology, in the case of Mundipharma as assignor or transferor, shall exclude any Patents and Information Controlled by any Acquiror (or any Affiliate thereof, excluding a Party hereto as a result of such transaction) except to the extent such Acquiror’s Information or Patents are Controlled by Allos or Mundipharma, as applicable, or any of Allos’ or Mundipharma’s, as applicable, Affiliates, and are necessary for the Development or Commercialization of Product and utilized in respect of the Product or the API in the Licensed Territory or the Allos Territory, as applicable.

14.7 Further Actions. Each Party agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

14.8 Severability.

14.9 No Waiver. Any delay in enforcing a Party’s rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written and signed waiver relating to a particular matter for a particular period of time.

14.10 Independent Contractors. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give either Party the power or authority to act for, bind, or commit the other Party in any way. Nothing herein shall be construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties.

80

14.11 English Language. This Agreement was prepared in the English language, which language shall govern the interpretation of, and any dispute regarding, the terms of this Agreement.

14.12 Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

14.13 Non-Solicitation of Employees. During the Term, neither Party may, directly or indirectly, recruit or solicit any employee of the other Party who became known to the other Party through contact or interactions for the purposes of negotiating or performing this Agreement, without the prior consent of the other Party. For purposes of the foregoing, “recruit” or “solicit” shall not include: (a) circumstances where an employee of a Party initiates contact with the other Party solely on its own with regard to possible employment without being encouraged, suggested, or otherwise induced to make such contact by the other Party; or (b) general solicitations of employment not specifically targeted at employees of a Party, including responses to general advertisements.

14.15 Intellectual Property. The Parties acknowledge and agree that the licenses granted by the Parties pursuant to Sections 2.1, 2.2 and 8.9 and all other rights granted under or pursuant to this Agreement are and shall otherwise be deemed to be, for purposes of Section 365(n) of the Bankruptcy Code (or analogous provisions of the bankruptcy laws of any Governmental Authority), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code (or analogous foreign provisions), and that this Agreement is an executory contract governed by Section 365(n) of the Bankruptcy Code (or analogous foreign provisions) in the event that a bankruptcy proceeding is commenced involving either Party (as licensor hereunder). Mundipharma, as the licensee of such rights under Section 2.1 and Allos, as the licensee of such rights under Section 2.2, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code.

14.16 Modification of Licensed Territory. As of the Effective Date, those countries in the Licensed Territory (as defined in the Original Agreement) that are no longer part of the Licensed Territory (as defined in this Agreement) (the “Transferred Countries”) have been removed from the Licensed Territory hereunder and transferred to the Allos Territory, and all of Mundipharma’s obligations under the Original Agreement and this Agreement shall be deemed terminated with respect to such Transferred Countries, save for (i) any unpaid obligations of Mundipharma accrued prior to the Effective Date, (ii) any indemnification obligations of Mundipharma under Section 10.2 with respect to Claims in the Transferred Countries brought after the Effective Date but arising out of, based on, or resulting from Mundipharma’s conduct prior to the Effective Date, and (iii) the transition assistance provisions of this Section 14.16. With respect to the Transferred Countries, Mundipharma shall, at its expense, cooperate with Allos and/or its designee to effect a smooth and orderly transition of the regulatory responsibilities and Development activities in the Transferred

81

Countries to the extent Mundipharma is then performing or having performed such activities. Mundipharma shall provide Allos copies of all Regulatory Materials filed in the Transferred Countries, all correspondence exchanged with the Regulatory Authorities in the Transferred Countries and other information relating to the Development or Commercialization of the Product in the Transferred Countries.From and after the Effective Date, upon the request of Allos, Mundipharma will, and will cause its Affiliates to, do, execute, acknowledge and deliver all such further acts, assurances, deeds, assignments, transfers, conveyances and other instruments and papers as may be reasonably required or appropriate to effect a smooth and orderly transition in the on-going Development activities of the Product in the Transferred Countries. For clarity, each party’s indemnification obligations are set forth in Section 10.

14.17 Switzerland Option. [***] the Term, Allos will have the option to remove the territory of Switzerland from the Licensed Territory and transfer it to the Allos Territory, which option may be exercised or terminated, at any time, by Allos by sending a written notice to Mundipharma (the “Switzerland Option”). Until such time as the Switzerland Option is exercised, Mundipharma will have the same obligations and responsibilities to conduct Development and Commercialization activities with respect to the Product in Switzerland as Mundipharma has for any other country in the Licensed Territory under this Agreement. Set forth in the Second Letter Agreement is (i) [***], and (ii) [***]. Mundipharma agrees to update such [***] on a [***] basis. Allos will have the right to review and approve such [***] updates to such [***], such approval not to be unreasonably withheld or delayed. Allos agrees to reimburse Mundipharma, (A) [***], and (B) [***]. Within [***] following the end of each [***] after the Effective Date, Mundipharma shall [***].

14.18 Amendment and Restatement. This Agreement amends and restates the Original Agreement in its entirety. Notwithstanding such amendment and restatement of the Original Agreement, each Party will retain all rights and obligations under the Original Agreement to the extent such rights and obligations have not been specifically amended by this Agreement and have (i) accrued prior to the Effective Date, or (ii) have not yet accrued by the Effective Date, but arise out of, are based on, or result from a Party’s conduct or an event occurring prior to the Effective Date.
