upon payment of all the Milestones described in clause 7.1 totalling up to $[********] million (“License Payment”), provided that if Iontas fails to perform its obligations under the Technology Transfer Plan for which

	16.7	 Unless otherwise expressly stated herein, Parent and 4AB may allocate the rights, assignments and obligations of
Agenus under this Agreement among

 FIRST AMENDMENT TO 

TECHNOLOGY TRANSFER AND LICENCE AGREEMENT 

THIS FIRST AMENDMENT (“Amendment”) is made as of the last date signed below 

BETWEEN 
  

	1	IONTAS LIMITED, a company incorporated under the laws of England (Company No. 06785483) with its registered office at 82B High Street, Sawston, Cambridgeshire CB22 3HJ, United Kingdom
(“Iontas”); 

  

	2	AGENUS INC., a company incorporated under the laws of Delaware with its principal place of business at 3 Forbes Road, Lexington, MA 02421-7305, USA (“Parent”, and on behalf of itself and its
affiliates, “Agenus”); and 

  

	3	4-ANTIBODY AG a wholly owned subsidiary of Parent incorporated under the laws of Switzerland with its principal place of business at Hochbergerstrasse 60C, CH-4057 Basel, Switzerland (“4AB”). 

 BACKGROUND 

 

	1	Iontas and Agenus are parties to that certain Technology Transfer and License Agreement dated September 25, 2015 (the “Original Agreement”). 


 

	2	Iontas and Agenus wish to amend the Original Agreement pursuant to Section 16.1 thereof to make certain adjustments to the Technology Transfer Plan and to provide for additional services as described herein.


  

	3	Defined terms used but not otherwise defined herein shall have the meanings ascribed to them in the Original Agreement. 

  

	1	AMENDMENT OBJECTIVES 

  

	1.1	 Agenus has requested, and Iontas has agreed, to certain changes to the Technology Transfer Plan described in
Exhibit A (the “Technology Transfer Plan Changes”) which include Iontas’ provision of 3 dedicated full-time Iontas employees solely for 










 EXECUTION COPY 

[********] = 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. 
  


	 	
Agenus directed activities (the “Initial FTEs”) for 5 months starting on the earliest of 1st November 2016 or the First Amendment Date (the “Start Date”), in
lieu of any yet unperformed portions of the Technology Transfer Plan. The aim of the Technology Transfer Plan Changes is to introduce more flexibility into the interaction between Agenus and Iontas. The parties agree that the Technology Transfer
Plan Changes shall come into effect upon First Amendment Date. 

  

	1.2	In addition to the 3 Initial FTEs, this Amendment also grants to Agenus the option to engage one or more additional Iontas full time employees (“Additional FTEs”) between the First Amendment Date and
the first anniversary thereof, subject to any extension agreed in writing between the parties (“Additional FTE Term”). The mechanics of engagement, disposition, management and disengagement of Additional FTEs agreed between the
parties are set out in clause 2 below. The Initial FTEs and any Additional FTEs are referred to collectively herein as the “Iontas FTEs”. 

  

	2	INITIAL FTE SERVICES AND ADDITIONAL FTE SERVICES 

  

	2.1	The parties agree to replace the pending milestone-based work and pending deliverables described in the Iontas Project and Agenus Training Project sections of the original Technology transfer Plan with the services of
the 3 Initial FTEs, with effect from the Start Date and continuing until the five-month anniversary thereof. 

  

	2.2	From time to time Agenus may request, and Iontas will provide, the services of one or more Additional FTEs subject to the terms and conditions herein. 


 

	2.3	 Agenus may from time to time notify Iontas that it wishes to deploy or redeploy some or all of the Iontas FTEs in
the performance of activities in the area of antibody engineering and selection by phage display on the Agenus library and Agenus materials only, including without limitation affinity maturation and candidate profiling (the “FTE
Services”). Iontas shall perform the FTE Services in accordance with Agenus’ written instructions provided by the appointed Agenus manager, with due care, skill and diligence consistent with industry standards, in accordance with the











 EXECUTION COPY 

[********] = 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. 
  


	 	
standards set forth in clauses 5 and 9 of the Original Agreement, provided that for purposes of this Amendment: (a) references to the “Iontas Project” in such clauses shall mean
the FTE Services, and (b) references to the “Technology Transfer Plan” in such clauses shall apply only to the extent the FTE Services include activities described in the Technology Transfer Plan, and shall otherwise mean Agenus’
written instructions for the applicable FTE Services. 

  

	2.4	The parties agree that the contents of all reports and all other confidential information, inventions, developments, data discoveries, improvements, ideas and any other works of inventorship or authorship generated,
conceived, discovered or reduced to practice or tangible medium by or on behalf of Iontas in performance of the FTE Services shall constitute Work Product as defined in Section 5.7 of the Original Agreement. 


 

	2.5	The FTE Services may include the expression of antibodies [********]. To provide such expression services a fee of $[********] will be separately invoiced (Expression Service Fee). 


 

	2.6	Except as expressly provided in this Agreement, Iontas shall be entitled to decline, on its own behalf and on behalf of the Iontas FTEs, any instruction from Agenus which, if followed, could, in Iontas’ reasonable
opinion, result in Iontas’ breach of any contractual obligation to a third party to refrain from carrying out any competing research and development activities. 


 

	2.7	The Iontas FTEs shall be fully dedicated to Agenus and shall not be assigned to perform work for other customers. 

  

	2.8	The Iontas FTEs will be and remain at all times employees of Iontas and all rights and obligations under their respective employment contracts, including but not limited to the terms of each such Iontas FTE’s
employment and the right to supervise and give instructions to the Iontas FTE, shall exclusively vest in Iontas, but Agenus, through the IONTAS Manager may direct the activities of each such Iontas FTE in connection with the performance of the FTE
Services as provided for hereunder, provided that such directions comply with applicable law and with Iontas’ internal rules and policies.

	2.9	Iontas shall provide Agenus with such periodic oral updates as may be reasonably requested from time to time. Iontas shall make all Iontas FTEs available to answer questions from Agenus regarding the FTE Services during
regular Iontas business hours. 

  

	2.10	In the event that Agenus requires Iontas to provide Additional FTEs it shall notify Iontas in writing at least 30 days prior to the proposed commencement date of the Additional FTEs’ performance of FTE Services
specifying the total number of FTE months required and the FTE Activities that will be performed by such Additional FTEs. The minimum commitment for the initial request for Additional FTEs shall be 3 FTE months and shall be subject to the
availability of appropriately qualified and experienced Iontas personnel. Agenus shall be entitled from time to time during the Additional FTE Term, upon at least 30 days’ notice in writing, to request Iontas to increase or decrease the number
of Additional FTEs, provided that: (a) any such increase shall be subject to the availability of appropriately qualified and experienced Iontas personnel; (b) any such decrease shall be subject to the minimum initial commitment specified
above; and (c) any such increase or decrease shall be in blocks of one FTE month. Agenus or Iontas may terminate the FTE Services with respect to one or all Additional FTEs on 3 months prior written notice to the other party. Subject to
continued compliance with the quality standards set out in clause 2.3 of this Amendment, Iontas shall be entitled to change the identity of any Additional FTE from time to time with the prior written consent of Agenus, such consent not to be
unreasonably withheld or delayed. 

  

	2.11	Agenus shall be entitled to request a change in the identity of any Iontas FTE on 30 days’ written notice to Iontas if Agenus reasonably determines that such Iontas FTE is not performing to the standards set forth
herein. 

  

	2.12	Each Iontas FTE will perform the FTE Services at the Facility using Iontas equipment and materials (but excluding IONTAS libraries), as well as the Research Materials (defined below), and will have the necessary
qualifications, expertise and training to perform the FTE Services to the standards of care set forth herein.

	2.13	Agenus shall appoint an Agenus Manager in relation to the Project who shall have the responsibility for directing the FTE Services. The Agenus manager shall be [********] or an alternative nominee confirmed in writing
to IONTAS. The Project Manager shall represent Agenus on all day-to-day matters relating to the FTE Services, provided however that no amendment to the Original
Agreement or this Amendment shall be valid or binding unless executed by an Agenus officer or vice president in accordance with Section 16.4 of the Original Agreement. Agenus shall use all reasonable commercial endeavours to ensure that the
same person acts as Agenus’s Manager throughout the Project, but may, upon reasonable written notice, replace him/her from time to time with a person of appropriate competence where reasonably necessary in the interests of Agenus’s
business. Agenus shall notify Iontas in advance of any such change. 

  

	2.12	Iontas shall appoint an Iontas Manager in relation to the Project who shall have the responsibility for directing the FTE services. The Iontas Manager shall be [********]. The Project Manager shall represent Iontas on
all day-to-day matters relating to the FTE Services, provided however that no amendment to the Original Agreement or this Amendment shall be valid or binding unless
executed by an Iontas officer in accordance with Section 16.4 of the Original Agreement. Iontas shall use all reasonable commercial endeavours to ensure that the same person acts as Iontas’s Manager throughout the Project, but may, upon
reasonable written notice, replace him/her from time to time with a person of appropriate competence where reasonably necessary in the interests of Iontas’s business. Iontas shall notify Agenus in advance of any such change 


 

	3	COMMERCIAL TERMS 

  

	3.1	 Clause 7 of the Original Agreement provided a schedule of milestone payments based on the achievement of certain
trigger events or milestone date. The parties agree that the values and payment terms for the remaining milestone payments shall be retained save that such payments shall no longer be conditional upon the

achievement of any specific milestones or trigger events. Such payments shall instead be deemed to be the consideration payable in respect of the Initial FTEs, provided that Iontas is in
compliance with its obligations under the Original Agreement as amended by this Amendment. In the event of any dispute arising out of or in connection with the Original Agreement (as amended by this Amendment) that cannot be resolved pursuant to
Article 15 of the Original Agreement, Agenus will pay Iontas pro-rata for the period preceding the dispute and undertake good faith efforts to resolve the dispute as set out in Clause 16 of the Original
Agreement. The revised invoicing schedule shall be as follows and the payment terms shall be as set out in clause 7.2 of the Original Agreement:

Material solely to perform the FTE Services and for no other purpose, and Iontas shall store, handle, transport and use the Research Material in accordance with all applicable laws and
regulations and as instructed by Agenus. Iontas shall use reasonable commercial efforts to keep the Research Material secure and safe from loss, damage, theft, misuse and unauthorized access. Iontas shall not distribute the Research Material to any

WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. AGENUS HEREBY DISCLAIMS ALL WARRANTIES, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT. EXCEPT AS EXPRESSLY PROVIDED
IN THIS AGREEMENT, AGENUS MAKES NO REPRESENTATIONS THAT THE RESEARCH MATERIALS ARE VIABLE, SAFE, NON-TOXIC OR FREE FROM CONTAMINANTS OR FROM ANY INFECTIOUS OR HARMFUL AGENTS. Without limiting the foregoing, Agenus agrees to disclose any known
hazardous properties and/or required specialized handling procedures to Iontas, and Iontas agrees that it shall use the Research Material in strict accordance with Agenus’s written instructions. Iontas shall not use the Research Material on
humans or animals. 

  

	4.3	The Research Material is owned by, and is the Confidential Information of, Agenus and shall remain the sole property of Agenus after Agenus provides such Research Material to Iontas. Agenus remains entitled to
distribute the Research Material to third parties and to use such Research Material for Agenus’s own purposes. The transmittal of the Research Material does not constitute and shall not be construed as the grant or transfer of a license or
other right by Agenus to Iontas with respect to the Research Material other than rights expressly granted to Iontas in this Agreement. Notwithstanding the exceptions set forth in the Original Agreement, (a) all information regarding the
Research Material shall constitute Confidential Information of Agenus, and (b) all information provided to Agenus in any reports or updates pursuant to clause 2.8 of this Amendment shall constitute Confidential Information of Agenus.
