ARTICLE II: LICENSES

2.1 Rights Granted by Agenus. Subject to the terms of this Agreement and, as applicable with respect to the relevant Agenus IP, any retained rights of LICR and MSKCC under the LICR Agreement, Agenus hereby grants Incyte, during the Term, an exclusive, royalty-bearing, non-transferable (except in accordance with Section 12.3) license or sublicense, as applicable, under the Agenus IP to Develop, Manufacture and Commercialize Licensed Antibodies and Products in the Territory and in the Field.

2.2 Rights Granted by Incyte. Subject to the terms of this Agreement, Incyte hereby grants to Agenus:

(a) a non-exclusive, royalty-free, non-transferable (except in accordance with Section 12.3) license or sublicense, as applicable, under the Incyte IP, solely to the extent necessary to permit Agenus and its Affiliates to exercise their respective rights and to perform their respective obligations under this Agreement; and

(b) a non-exclusive, fully paid-up, sublicensable license or sublicense, as applicable, under the Incyte Program Patent Rights and the Incyte Program Know-How to Develop, Manufacture and Commercialize Licensed Antibodies and Products (excluding Combination Products) in the Territory outside of the Field.

2.3 Sublicense Rights.

(a) Each Party shall have the right to grant sublicenses under the licenses granted to the other Party under Sections 2.1 and 2.2 to its Affiliates and, subject to Sections 2.3(b)-(d), as applicable, to Third Parties.

(b) Incyte and its Affiliates may freely sublicense the Agenus IP to Third Parties, directly or indirectly, through multiple tiers, except that any sublicense under Agenus IP (i) licensed to Agenus by LICR pursuant to the LICR Agreement shall require the prior written consent of Agenus (such consent not to be unreasonably withheld, delayed or conditioned), and (ii) Covering the Commercialization of a Product in the Field shall be subject to the provisions of subsection (d) below. Incyte shall provide Agenus with a copy of any such sublicense agreement within [**] after the execution thereof. Each sublicense of the Agenus IP shall be consistent with the terms and conditions of this Agreement and, if applicable, the LICR Agreement as set forth in Section 2.6 below, and Incyte shall guarantee the performance of its Affiliates and permitted sublicensees with respect to any sublicense granted pursuant to this Section 2.3(b).

(c) Agenus may freely sublicense the rights granted to Agenus under the Incyte Program Patent Rights and the Incyte Program Know-How outside of the Field to Third Parties, subject to the provisions of Section 2.7. Agenus shall provide Incyte with a copy of any

such sublicense agreement within [**] after the execution thereof. Each sublicense of the Incyte Program Patent Rights or Incyte Program Know-How outside of the Field shall be consistent with the terms and conditions of this Agreement, and Agenus shall guarantee the performance of its permitted sublicensees with respect to any sublicense granted pursuant to this Section 2.3(c).

(d) In the event that Incyte desires to commence negotiations with any Third Party (other than Permitted Subcontractors or Third Party distributors) to license and sublicense all or a portion of Incyte’s Program Rights to Commercialize a Product in the Field, Incyte shall promptly notify Agenus of its intent to enter into such a transaction, identifying the specific Product that will be the subject of such transaction. Within [**] after receipt of such notification (the “ROFN Trigger Period”), Agenus shall notify Incyte in writing either that (i) Agenus is interested in negotiating an agreement with respect to such Program Rights (the “Negotiation Notice”) or (ii) Agenus has no interest and therefore waives its right of first negotiation with respect to such Program Rights. If Agenus notifies Incyte in writing within such [**] period that Agenus desires to negotiate an agreement with respect to such Program Rights, the Parties shall negotiate in good faith for up to [**] from the date of such notification (the “Negotiation Period”), or such longer period as agreed between the Parties, regarding the terms pursuant to which the Parties would enter into a transaction with respect to such Program Rights. Failure by Agenus to give written notice of its interest or lack of interest in negotiating such agreement within [**] after receipt of written notice from Incyte as described in the first sentence of this Section 2.3(d) shall be deemed to constitute a waiver by Agenus of its right of first negotiation with respect to such Program Rights. If Agenus provided the Negotiation Notice within the ROFN Trigger Period, but Incyte and Agenus are unable to reach agreement during the Negotiation Period, Incyte may offer its Program Rights in the applicable Product to a Third Party; provided, however, that [**].

2.4 Section 365(n).

(a) All rights and licenses granted under or pursuant to any section of this Agreement, including all rights to sublicense, are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11 of the U.S. Code (the “Bankruptcy Code”), licenses of rights to “intellectual property” as defined in Section 101(35A) of the Bankruptcy Code. The Parties shall retain and may fully exercise all of their respective rights and elections under the Bankruptcy Code. Each Party agrees that the other Party, to the extent that it is a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code, and that upon commencement of a bankruptcy proceeding by or against one Party under the Bankruptcy Code, the other Party shall be entitled to a complete duplicate of or complete access to (as such other Party deems appropriate), any such intellectual property and all embodiments of such intellectual property, provided that such other Party continues to fulfill its obligations as specified herein in full. Such intellectual property and all embodiments thereof shall be promptly delivered to the other Party (i) upon any such commencement of a bankruptcy proceeding upon written request therefor by the other Party, unless the Party subject to such bankruptcy proceeding elects to continue to perform all of its obligations under this Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on behalf of the Party subject to such bankruptcy proceeding, upon written

request therefor by the other Party. The foregoing is without prejudice to any rights that either Party may have arising under the Bankruptcy Code or other applicable law.

(b) Nothing in this Section 2.4 shall be deemed any admission that this Agreement is an executory contract or that this Agreement or any obligation hereunder is otherwise subject to rejection or disavowal in the bankruptcy, liquidation, reorganization, receivership, assignment for the benefit of creditors, administration, insolvency, or similar proceeding or circumstance (an “Insolvency Proceeding”) of any Party, nor any admission that upon any such proceeding or circumstance involving a Party, or upon any such rejection or disavowal by a Party, the other Party (or any sublicensee thereof) would lose or not be able to enforce or benefit from any right hereunder (or under any applicable sublicense.

(c) Each of the Parties agrees and acknowledges, as a licensor of intellectual property under this Agreement, in entering this Agreement and granting the rights it respectively grants under this Agreement, and in its efforts to protect its own valuable intellectual property, it has relied on the particular skills and business qualities of the other Party as recipient of such rights. Such skills and business qualities include the expected future innovation of the other Party, and the particular market segments addressed by the other Party in its business. Each of the Parties further agrees and acknowledges that upon the occurrence of any Insolvency Proceeding, this Agreement is of the type described in Section 365(c)(1) and (e)(2) of the Bankruptcy Code, and under any other applicable Law, for such reasons.

2.5 No Implied Licenses or Rights; Retained Rights.

(a) No Implied Licenses or Rights. Except as expressly provided in Section 2.1 or elsewhere in this Agreement, all rights in and to the Agenus IP, and any other Patent Rights or Know-How of Agenus and its Affiliates, are hereby retained by Agenus and its Affiliates. Except as expressly provided in Section 2.2 or elsewhere in this Agreement, all rights in and to the Incyte IP, and any other Patent Rights or Know-How of Incyte and its Affiliates, are hereby retained by Incyte and its Affiliates. For the purposes of clarity, and notwithstanding any other provision of this Agreement, the licenses granted in Section 2.1 give Incyte no rights to utilize or exploit, (i) the Agenus IP, a Licensed Antibody or a Product outside of the Field, (ii) the Retrocyte Display Technology, Retrocyte Display Improvements, or any Patent Rights or Know-How Controlled by Agenus and its Affiliates Covering the foregoing, or (iii) Patent Rights or Know-How Controlled by Agenus and its Affiliates Covering a Vaccine (including the Prophage Series Vaccines), adjuvant (including the QS-21 Stimulon adjuvant) or heat shock protein technologies.

(b) Retained Rights. Notwithstanding the exclusive licenses granted to Incyte pursuant to Section 2.1, Agenus retains the right to practice under the Agenus IP (i) to exercise its rights and to perform (and to sublicense Third Parties to perform) its obligations under this Agreement and (ii) for all purposes outside of the Field, subject to the provisions of Section 2.7.

2.6 LICR Agreement. Incyte acknowledges and agrees that certain of the licenses hereunder are subject to the following terms and conditions of the LICR Agreement: (a) the reporting and record-keeping obligations with respect to sales of Products as provided in

- 25 -

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

EXHIBIT 10.22

CONFIDENTIAL TREATMENT MATERIAL

Sections 2.6 and 3.8 of the LICR Agreement, (b) indemnification under Section 5.4(a)(ii) of the LICR Agreement, and (iii) obligations of non-use of name as provided in Section 6.5 of the LICR Agreement. In the event of any conflict or inconsistency between any applicable provision of this Agreement and such provisions of the LICR Agreement, such provisions of the LICR Agreement shall prevail with respect to the relevant Agenus IP licensed to Agenus by LICR pursuant to the LICR Agreement, except to the extent such inconsistency results from a breach by Agenus of Section 10.6. For purposes of clarity, all financial obligations of Agenus under the LICR Agreement shall be the sole responsibility of Agenus.

2.7 Non-Compete.

(a) [**], neither Agenus nor, subject to Section 12.3(b)(ii), its Affiliates shall Develop, Manufacture or Commercialize outside of the Field any Licensed Antibody or Product that is identified in, and is being Developed, Manufactured or Commercialized under, a Development Plan or Commercialization Plan hereunder.

(b) [**], neither Incyte nor, subject to Section 12.3(b)(ii), its Affiliates shall Develop, Manufacture or Commercialize any Licensed Antibody or Product outside of the Field.

(c) [**], neither Party nor, subject to Section 12.3(b)(ii), any of its Affiliates, shall independently, or with a Third Party, conduct Development of, Manufacture or Commercialize in the Territory any Antibody that Interacts with a Named Target (including, for clarity, any Licensed Antibody) or a Bullpen Target, or a therapeutic preparation containing such an Antibody, in the Field other than as part of the Program, except (i) if the prior written consent of the other Party has been obtained, (ii) in the case of a Party, for any Antibody that Interacts with a Bullpen Target that is the subject of a Discovery Project that the other Party has declined to include in the Program as an Assumed Project pursuant to Section 4.5(b)(ii), so long as such Antibody does not Interact with a Named Target or another Bullpen Target, (iii) each Party may conduct preclinical or other nonclinical research (including screening and comparative pharmacology) using an Antibody obtained from a Third Party or owned by a Third Party in order to help advance and position the efforts of the Parties in the Program, and (iv) each Party may screen any Antibody for purposes of determining that such Antibody does not Interact with a Named Target or a Bullpen Target. For clarity, if the JSC elects to remove a Target from the list of Bullpen Targets, any Antibody that Interacts with such Bullpen Target shall no longer be subject to this Section 2.7(c) but only if such Antibody does not Interact with a Named Target or another Bullpen Target.

(d) During the period beginning on the Effective Date and ending [**] thereafter or, if later, the expiration of the PD-1 Negotiation Period, neither Incyte nor, subject to Section 12.3(b)(ii), any of its Affiliates, shall independently, or with a Third Party, conduct Development of, Manufacture or Commercialize in the Territory any Antibody that Interacts with PD-1, or a therapeutic preparation containing such an Antibody, in the Field except (i) if the prior written consent of Agenus has been obtained, and (ii) Incyte may screen any Antibody for purposes of determining that such Antibody does not Interact with PD-1.

EXHIBIT 10.22

CONFIDENTIAL TREATMENT MATERIAL

(e) In the event either Party or its Affiliate acquires control (as “control” is defined in Section 1.2) of any Third Party, the activities of such Third Party shall not constitute a breach of this Agreement; provided that (i) no later than [**] following consummation of the transaction in which such Party or its Affiliate acquires control of such Third Party, the acquiring Party or Affiliate takes appropriate action, through presentation of the applicable product to the other Party pursuant to Section 4.5, divestiture of assets, or otherwise, to cause such Party to come into compliance with the terms of this Agreement; (ii) during such [**] period, the acquiring Party or Affiliate keeps such acquired Third Party’s activities with respect to the Antibodies and therapeutic preparations that would otherwise breach Sections 2.7(a), 2.7(b), 2.7(c) or 2.7(d) separate from the Development, Manufacturing and Commercialization programs for Licensed Antibodies and Products, and ensures that no Confidential Information is utilized in such activities; and (iii) the acquiring Party continues to meet its other obligations hereunder.

(f) In the event that a Party undergoes a Change in Control, then the research, development, manufacture or commercialization in the Field in the Territory of an Antibody that Interacts with a Named Target or a Bullpen Target, or a therapeutic preparation containing such an Antibody, that, as of the date of such Change in Control is being researched, developed, manufactured or commercialized by the assignee or acquirer of such Party, or any Person which, immediately prior to such Change in Control, is an Affiliate of such assignee or acquirer, shall not constitute a breach of this Agreement; provided that (i) such assignee or acquirer or Affiliate keeps such research, development, manufacturing or commercialization program for such other Antibody, and any products containing such an Antibody, separate from the Development, Manufacture and Commercialization programs for Licensed Antibodies and Products, and ensures that no Confidential Information is utilized in such program; and (ii) the acquired or assigning Party continues to meet its obligations hereunder.

2.8 PD-1 Negotiation Right. In the event that Agenus desires to commence negotiations with a Third Party with respect to the grant of commercialization rights in the Field for PD-1 Antibodies in North America and/or the European Union (the “▇▇-▇ ▇▇▇▇▇▇▇▇▇”) at any time during the period beginning on the Effective Date and ending [**] thereafter or if, during such period, Agenus desires to continue such negotiations which were begun on or after the Execution Date but before the Effective Date, Agenus shall promptly notify Incyte of its intent to enter into such a transaction. Within [**] after receipt of such notice (the “PD-1 Trigger Period”), Incyte shall notify Agenus in writing either that (i) Incyte is interested in negotiating an agreement with respect to such PD-1 Antibodies in the Field in all or a portion of the ▇▇-▇ ▇▇▇▇▇▇▇▇▇ (the “PD-1 Negotiation Notice”) or (ii) Incyte has no interest and therefore waives its right of first negotiation. If Incyte notifies Agenus in writing within the PD-1 Trigger Period that Incyte desires to negotiate an agreement, the Parties shall negotiate in good faith for up to [**] from the date of such notification (the “PD-1 Negotiation Period”), or such longer period as agreed between the Parties, regarding the terms pursuant to which the Parties would enter into a transaction with respect to such PD-1 Antibodies in the Field in the ▇▇-▇ ▇▇▇▇▇▇▇▇▇. Failure by Incyte to give written notice of its interest or lack of interest in negotiating such agreement within the PD-1 Trigger Period in all or a portion of the ▇▇-▇ ▇▇▇▇▇▇▇▇▇ shall be deemed to constitute a waiver by Incyte of its right of first negotiation. If Incyte provided the PD-1 Negotiation Notice within the PD-1 Trigger Period, but Incyte and Agenus are unable to reach

ARTICLE III: GOVERNANCE

3.1 Joint Steering Committee.

(c) Establishment. The Parties shall establish a joint steering committee (“JSC”) within thirty (30) days after the Effective Date that will have the responsibility for the overall coordination and oversight of the Development, Manufacture and Commercialization of Licensed Antibodies and Products under this Agreement. As soon as practicable following the Effective Date (but in no event more than thirty (30) days following the Effective Date), each Party shall designate its initial three (3) representatives on the JSC. Each Party’s representatives and any substitute for a representative shall be bound by the obligations of confidentiality set forth in Article XI. A representative from Incyte shall act as the chairperson of the JSC; provided, however, that following consummation of a Change in Control of Incyte, a representative from Agenus shall act as the chairperson of the JSC. The chairperson shall not have any greater authority than any other representative on the JSC, but shall be responsible for the following activities: (i) calling meetings of the JSC; (ii) preparing and issuing minutes of each such meeting within thirty (30) days thereafter; (iii) ensuring that any decision-making delegated to the JSC is carried out in accordance with Section 3.5; and (iv) preparing and circulating an agenda for the upcoming meeting; provided that the chairperson shall include any agenda items proposed by the other Party. Each Party shall be free to change its representatives on notice to the other Party or to send a substitute representative to any JSC meeting; provided, however, that each Party shall ensure that at all times during the existence of the JSC, its representatives on the JSC are appropriate in terms of expertise and seniority for the then-current stage of Development or Commercialization of the Products.

(d) Responsibilities. The JSC shall have responsibility for: (i) overseeing the initial transfer of information and designated activities between the Parties relating to the Development of Licensed Antibodies and Products; (ii) providing general oversight over the Development of Licensed Antibodies and Products, including the periodic review and approval of the Development Plans (and any material updates, amendments and modifications thereto) and the review and evaluation of the progress under the Development Plans; (iii) reviewing, amending and, subject to Sections 4.1(c) and 4.4(b), approving the Development budget for each Project; (iv) selecting Indications for Development of Products in the Field; (v) determining which of the Parties will be responsible for Regulatory Interactions with respect to a Product; (vi) reviewing the regulatory approach and filing strategy with respect to seeking and obtaining Regulatory Approval of Products in the Field in the Territory; (vii) determining which of the Parties will be responsible for selecting and monitoring the Manufacturing vendors and otherwise being responsible for Manufacturing activities with respect to Products; (viii) managing the list of Bullpen Targets, including adding and removing Targets from such list; (ix) discussing potential Discovery Projects; (x) developing a Publication plan for each Project and approving all Publications; (xi) providing general oversight over the Commercialization of Products, including the periodic review and approval of the Commercialization Plans for the Profit-Share Products (and any material updates, amendments and modifications thereto); (xii)

reviewing, amending and, subject to Section 5.1(b), approving the Commercialization budget for Profit-Share Products; and (xiii) performing such other functions as expressly set forth in this Agreement or appropriate to further the purposes of this Agreement, as mutually agreed upon by the Parties in writing.

3.2 Project Management Teams; Other Subcommittees. The JSC shall establish one or more project management teams (each, a “Project Management Team”) with one such Project Management Team being established for each Project unless otherwise agreed by the JSC (and, for clarity, the JSC may instead determine that there should be a single Project Management Team for the Program, or different Project Management Teams for early stage vs. late stage Development activities for all Projects, or any other approach approved by the JSC). The Project Management Teams shall have responsibility for coordinating, expediting and controlling the Development of Products to obtain Regulatory Approvals. Each Project Management Team will, with respect to the applicable Project (unless otherwise agreed by the JSC), (a) develop and recommend to the JSC updates to the Development Plan (including annual Development budgets), (b) facilitate the flow of information with respect to Development work being conducted for each Product in the Territory, and (c) discuss and cooperate regarding the conduct of such Development work. The JSC may establish and disband such other subcommittees as deemed necessary by the JSC (each, a “Subcommittee”). Each Project Management Team and Subcommittee shall consist of the same number of representatives designated by each Party, which number shall be mutually agreed by the Parties. For the avoidance of doubt, either Party may designate the same representatives to serve on multiple or all Project Management Teams or Subcommittees or on the JSC and any Project Management Team or Subcommittee. Each Party shall be free to change its representatives on notice to the other or to send a substitute representative to any Project Management Team or Subcommittee meeting; provided, however, that each Party shall ensure that at all times during the existence of any Project Management Team or Subcommittee, its representatives on such Project Management Team or Subcommittee are appropriate in terms of expertise and seniority for the then-current stage of Development of the applicable Products in the Field in the Territory. Each Party’s representatives and any substitute for a representative shall be bound by the obligations of confidentiality set forth in Article XI. No Project Management Team or Subcommittee shall have the authority to bind the Parties hereunder and each Project Management Team or Subcommittee shall report to, and any decisions shall be made by, the JSC.

3.3 Committee Meetings. The JSC and each of the Project Management Teams and Subcommittees shall each hold at least one (1) meeting per Calendar Quarter at such times during such Calendar Quarter as the chairperson elects to do so. Except where a Party fails to appoint a member or members to the JSC or the Project Management Teams or Subcommittees or fails to participate in meetings of the JSC or the Project Management Teams or Subcommittees pursuant to Section 3.6, meetings of the JSC and the Project Management Teams or Subcommittees, respectively, shall be effective only if at least one (1) representative of each Party is present or participating. The JSC and each Project Management Team or Subcommittee may meet either (a) in person at either Party’s facilities in the United States or at such locations as the Parties may otherwise agree or (b) by audio or video teleconference; provided that no less than one (1) JSC meeting during each Calendar Year shall be conducted in person. Other

EXHIBIT 10.22

CONFIDENTIAL TREATMENT MATERIAL

representatives of each Party involved with the relevant Products may attend meetings as non-voting participants, subject to the confidentiality provisions set forth in Article XI. Additional meetings of the JSC, Project Management Teams or Subcommittees may also be held with the consent of each Party, and neither Party shall unreasonably withhold its consent to hold such additional meetings, or as required under this Agreement. Each Party shall be responsible for all of its own expenses incurred in connection with participating in all such meetings, and such expenses shall not be Development Costs or Allowable Expenses hereunder.

3.4 Authority. The JSC, each Project Management Team and any Subcommittee shall have only the powers assigned expressly to it in this Article III and elsewhere in this Agreement, and shall not have any power to amend, modify or waive compliance with this Agreement. In furtherance thereof, each Party shall retain the rights, powers and discretion granted to it under this Agreement and no such rights, powers or discretion shall be delegated or vested in the JSC or any Project Management Team or Subcommittee unless such delegation or vesting of rights is expressly provided for in this Agreement or the Parties expressly so agree in writing.

3.5 Decisions.

(a) Initial Dispute Resolution Procedures. Subject to the provisions of this Section 3.5, actions to be taken by the JSC and each of the Project Management Teams or Subcommittees shall be taken only following a unanimous vote, with each Party (through its representatives) having one (1) vote. If any Project Management Team or Subcommittee fails to reach consensus on a matter before it for decision for a period in excess of thirty (30) days, either Party shall have the right to refer the matter to the JSC.

(b) Final Decision-Making. If the JSC fails to reach unanimous agreement on a matter properly before it (in accordance with this Article III) for decision for a period in excess of thirty (30) days, the JSC representatives appointed by Incyte shall have the deciding vote; provided, however, that after the consummation of a Change in Control of Incyte, Agenus shall have the deciding vote with respect to all matters subject to approval by the JSC relating to the Profit-Share Projects. The Party that does not have the deciding vote shall have the right to appeal any such decision of the JSC to the Executive Officers for resolution pursuant to Section 12.2.

(c) Limits on Decision-Making. Notwithstanding the foregoing, a Party shall not exercise its right to finally resolve a dispute pursuant to Section 3.5(b): (i) in a manner that expands such Party’s rights or excuses such Party from any of its obligations specifically enumerated under this Agreement; (ii) in a manner that negates any consent rights or other rights specifically allocated to the other Party under this Agreement; (iii) in a manner that imposes additional Development Costs or Allowable Expenses on the other Party which would not be reimbursed hereunder by the resolving Party, except as expressly provided in Sections 4.1(c), 4.4(b) or 5.1(b); (iv) to resolve any dispute regarding whether a milestone event set forth herein has been achieved; (v) to designate or undesignate a Target as a Bullpen Target; (vi) to determine whether an Antibody that binds specifically with more than one Target shall not be deemed to Interact with whichever such Target it binds to with greatest affinity; or (vii) in a manner that

EXHIBIT 10.22

CONFIDENTIAL TREATMENT MATERIAL

would require a Party to perform any act that it reasonably believes to be inconsistent with any Law or any approval, order, policy or guidelines of a Regulatory Authority.

3.6 Committee Membership.

(g) Appointment is a Right. The appointment of members of the JSC and any Project Management Team or Subcommittees is a right of each Party and not an obligation and shall not be a “deliverable” as referenced in any existing authoritative accounting literature. Each Party shall be free to determine not to appoint members to the JSC or any Project Management Team or Subcommittee.

(h) Consequence of Non-Appointment. If a Party does not appoint members of the JSC or any Project Management Team or Subcommittee, it shall not be a breach of this Agreement, nor shall any consideration be required to be returned, and unless and until such members are appointed, the Party that has made the requisite appointments may unilaterally discharge the roles of the JSC or any Project Management Team or Subcommittee for which members were not appointed, provided that neither Party shall unilaterally discharge the roles of the JSC or any Project Management Team or Subcommittee as permitted under this Section 3.6(b) unless the other Party has not appointed any members within thirty (30) days after the first Party has completed its appointment of its members.

3.7 Future Adjustments in Governance. The Parties may at any time by mutual written agreement create or delete governance committees or subcommittees or make other modifications to the governance structures contemplated by this Agreement in order to promote the efficient operation of the Program.

ARTICLE IV: DEVELOPMENT

4.1 Conduct of Development Activities.

(e) Generally. Each Party shall use Commercially Reasonable Efforts to Develop and obtain Regulatory Approvals for Products in the Field and in the Territory as soon as practicable, all in accordance with the Development Plan for such Products. Without limiting the foregoing, the Parties shall use Commercially Reasonable Efforts to Develop at least [**] Licensed Antibody or Product arising out of each Project until the first BLA for a Product arising out of such Project has been filed. Without limiting the foregoing, the Parties shall also use Commercially Reasonable Efforts to cause the first IND for a Profit-Share Product or a Product containing a ▇▇▇-3 Antibody to be filed on or before [**]. The Parties agree to cooperate with each other in carrying out the Development Plan for each Product. Neither Party shall be required to undertake activities in furtherance of the Development Plan if the other Party is not meeting its funding, technology transfer or other commitments set forth in this Agreement that are reasonably necessary to have been performed in order for the such first Party to perform the relevant activities under the Development Plan.

(f) Development Plans. The Development activities with respect to each Project shall be conducted by the Parties under a development plan and associated budget (each, a “Development Plan”) that will describe the proposed overall program of Development for

- 31 -

[**] = Portions of this exhibit have been omitted pursuant to a confidential treatment request. An unredacted version of this exhibit has been filed separately with the Commission.

EXHIBIT 10.22

CONFIDENTIAL TREATMENT MATERIAL

each Product therein, including preclinical studies, toxicology, formulation, Clinical Trials and regulatory plans and other key elements necessary to obtain Regulatory Approvals for such Product. For each Project, the Development Plan shall encompass: (i) with respect to Products for which an IND filing has not occurred, a rolling one (1) Calendar Year period; and (ii) with respect to Products which an IND filing has occurred, a rolling three (3) Calendar Year period. Each Development Plan shall include a summary of estimated Development Costs expected during the Development process during the applicable time period and a detailed description of and budget for all Development activities proposed for each Calendar Year for each Product.

(g) Initial and Updated Development Plan. The JSC shall use reasonable efforts to agree upon an initial high-level Development Plan for each Project for the period beginning on the Effective Date and ending on December 31, 2015 within one hundred twenty (120) days of the Effective Date, provided that until such Development Plan has been adopted by the JSC, the Parties will work in good faith on the commencement of activities for each Project in accordance with the preliminary action plan and associated budget set forth in Schedule 4.1 and any Development costs incurred thereunder shall be considered Development Costs hereunder. Each Development Plan shall be updated at least annually by Incyte, in consultation with Agenus, and in each case submitted to the JSC for review and approval not later than October 31 of each Calendar Year during the Term. Each such updated Development Plan shall include, with respect to the relevant Project, and the Products therein, to the extent possible, (i) an outline of an overall Development plan for each Product that sets forth all major Development tasks remaining to be accomplished prior to submission of filings for Regulatory Approvals to the extent such tasks are known or can reasonably be ascertained, (ii) a detailed description of, and allocation of responsibility for, all proposed Development activities for the time period applicable to each such Product, and (iii) a detailed financial forecast containing a committed budget for the next Calendar Year and, solely for Products for which an IND has been filed, good faith estimates of the budget for the following two (2) Calendar Years. The members of each Project Management Team, on a Project-by-Project basis, shall actively consult with one another throughout the Term so as to adjust the specific work performed under the applicable Development Plan to conform to evolving developments in technology and the results of the Development work performed; provided, however, that, while minor adjustments to such Development Plan that do not result in budgeted funding exceeding [**] of the then-total amount budgeted in any Calendar Year for such Project may be made from time to time upon approval of the applicable Project Management Team, significant changes in the scope or direction of the work and any changes in budgeted funding exceeding [**] of the then-total amount budgeted in any Calendar Year for such Project must be approved by the JSC, in the absence of which approval the most recently approved Development Plan and budget shall remain in effect. Notwithstanding the foregoing, if the JSC does not approve the budget increase and such increase is (1) associated with an activity for which one of the Parties has primary responsibility as described in Section 4.1(d) below, the Party responsible for such activity may fund such activity itself and such expenditure shall not be a Development Cost or Allowable Expense, as applicable, hereunder, or (2) subject to clause (1), associated with an activity for which Agenus has primary responsibility as described in Section 4.1(d) below, Incyte may, in its sole discretion, fund such activity and such expenditure shall be considered an Allowable Expense if such expenditure relates to a Profit-Share Product or a Profit-Share Project but will only be included

(r) Recoveries. To the extent that any such suit or action pertains to any Product, any recovery obtained as a result of any proceeding described in Section 6.3(b) or from any counterclaim or similar claim asserted in a proceeding described in Section 6.4, by settlement or otherwise, shall be applied in the following order of priority:

connection with the defense of a Third Party Infringement Claim, and any Losses payable by either Party as a result thereof, (a) shall be Patent and Trademark Costs hereunder if the relevant Product to which such Third Party Infringement Claim pertains is a Profit-Share Product, and (B) otherwise shall be borne by the Party that is primarily responsible for the activity that is the subject of the Third Party Infringement Claim.

6.5 Patent Invalidity Claim. If a Third Party at any time asserts a claim that any Agenus Patent Right, Incyte Program Patent Right or Joint Patent Right Covering a Product is invalid or otherwise unenforceable (an “Invalidity Claim”), whether as a defense in an infringement action brought by Agenus or Incyte pursuant to Section 6.3(b), in a declaratory judgment action or in a Third Party Infringement Claim brought against Agenus or Incyte, the Party Controlling such Patent Right (or Incyte with respect to any Joint Patent Right) shall have the first right, but not the obligation, to defend such Invalidity Claim and the other Party shall cooperate with the Party Controlling such Patent Right in preparing and formulating a response to such Invalidity Claim. If Agenus does not defend an Invalidity Claim brought against an Agenus Patent Right or Incyte does not defend an Invalidity Claim brought against an Incyte Program Patent Right or Joint Patent Right, the other Party may defend such Invalidity Claim and the coordination provisions of Section 6.3(b) shall apply to such Invalidity Claim, mutatis mutandis as they apply to Licensed IP Infringement suits. Neither Party shall, without the consent of the other Party, settle or compromise any Invalidity Claim in any manner which would (a) have an adverse effect on such other Party’s Patent Rights or such other Party’s Program Rights hereunder or (b) be an admission of liability on behalf of such other Party (provided, however, that the Party initiating such suit may settle such suit without such consent if such settlement involves only the receipt of money from, or the payment of money to, such Third Party and the Party initiating such suit makes all such payments to such Third Party). To the extent such Invalidity Claim is raised as a defense in an infringement action brought by Agenus or Incyte pursuant to Section 6.3(b), the expense provisions of Section 6.3 shall apply and counsel to the Party controlling the infringement action shall act as the ministerial liaison with the court. To the extent such Invalidity Claim is raised in a Third Party Infringement Claim brought against a Party, the expense provisions of Section 6.4 shall apply with respect thereto and the Party against whom the Invalidity Claim is brought shall act as the ministerial liaison with the court.

6.6 Patent Term Extensions. Incyte shall have the sole authority to obtain Patent Term Extensions for Patent Rights Covering a Product; provided, however, that Incyte shall reasonably consider any input from Agenus with respect to the extension of any Agenus Patent Rights. Agenus shall, as applicable, file all documentation and take all other actions to obtain such Patent Term Extensions.

6.7 Patent Marking. Incyte shall comply with all applicable patent marking statutes in any country in which Products Covered by Agenus Patent Rights or Joint Patent Rights are sold.

The alliance will initially focus on the development of checkpoint modulator antibodies directed against GITR, ▇▇▇▇, ▇▇▇-▇ and ▇▇▇-3. Agenus and Incyte will share all costs and profits for the GITR and OX40 antibody programs on a 50:50 basis, with Agenus eligible for potential milestones; ▇▇▇-3 and LAG-3 are royalty-bearing programs to be funded by Incyte, with Agenus eligible for potential milestones and royalties. The first clinical trials are expected to be initiated in 2016.

In addition to the initial four target programs in the alliance, the parties have an option to jointly nominate and pursue additional targets within the framework of the multi-year collaboration. Terms also include:


•	For each royalty-bearing product, Agenus will be eligible to receive up to $155 million in future contingent development, regulatory and commercialization milestones.


•	Also for royalty-bearing products, Agenus will be eligible to receive tiered royalties on global net sales ranging from mid-single to low-double digit rates, and has reserved the right to elect to co-fund 30% of development costs for increased royalties.


•	For products from any additional programs that the parties elect to bring into the collaboration, Agenus may opt to designate them as profit-share products.


•	For each profit-share product, Agenus will be eligible to receive up to $20 million in future contingent development milestones.

Determination by the Expert. The Expert shall, no later than [**] after the last submission of the written reports and, if any, oral submissions, select one of the Party’s positions as his or her final decision, and shall not have the authority to modify either Party’s position or render any substantive decision other than to so select the position of either Party as set forth in their respective written report (as initially submitted, or as revised in accordance with this Schedule 12.2, as applicable). The Parties agree that the decision of the Expert shall be the sole, exclusive and binding remedy between them regarding any such dispute referred to the Expert pursuant to Section 12.2 of this Agreement, and the Expert’s decision shall become the decision of the Parties or, if applicable, the JSC on the matter.
