Notwithstanding anything to the contrary herein, Company or Adicet shall not owe to Licensor (and Licensor shall not be entitled to receive) royalties based on any amounts received by Adicet, AIT or their respective Subsidiaries or Downstream

1.4    Section 7.3 of the License Agreement is amended and restated to read in full as follows: 

“7.3 Royalty Period and No Adjustments. “Royalty Period” shall mean, with respect to each Licensed Product,
[***] after the First Commercial Sale of such Licensed Product, on a Licensed Product-by-Licensed Product basis. There shall be no adjustments or offsets to the royalty obligations hereunder (including, without limitation, adjustments or offsets for
combination products, third party royalty stacking, generic products, M&A or time based adjustments). Other than the payments expressly set forth in Sections 7.1 and 7.2, Adicet, AIT and their respective Affiliates shall not owe to Licensor
any payments in connection with the sale of Licensed Products or the sublicense of the Licensed Technology or Joint Researcher Improvements. For the avoidance of any doubt, nothing herein shall derogate from the commitment by the Company to pay for
the preparation, filing, prosecution, protection and maintenance of all patents and patent applications within the Licensed Technology and Joint Researcher Improvement Patent Rights in accordance with Section 9 to the License Agreement
and to fund the research in Researcher’s laboratory at the Technion relating to [***] complexes recognized by T-Cells during the Initial Research Period as stated in Amendment No. 1.”

1.6    In the event of a termination pursuant to Section 14.3(a) (“Termination without Cause”), the
obligations of Company to pay royalties under Section 7 of the License Agreement and Adicet to pay royalties under Section 2 of this Amendment shall survive such termination with respect to those Licensed Products for which
an IND was granted prior to the date of such termination ([***]) as well as any obligations which in accordance with the License Agreement are intended to survive termination. 

2.    Adicet shall be bound by the obligations under Section 7 (“Consideration for Grant of License”) (as
amended hereby) and Section 8 (“Reports; Payments; Records”) of the License Agreement with respect to sales of any Licensed Product by Adicet, its Subsidiaries or Downstream Affiliates, or Sublicensees, its Subsidiaries or
Affiliates. It is hereby clarified that this provision shall not be affected by any termination or assignment of the License Agreement or any disposition of AIT or AIT’s assets or securities.

 3.    Without derogating or amending the provisions of Section 2
above in any manner and in addition thereto, Adicet shall also be jointly and severally bound by the obligations of AIT under the License Agreement, including without limitation Section 7 (“Consideration for Grant of License”)
(as amended hereby) and Section 8 (“Reports; Payments; Records”) of the License Agreement, with respect to the Licensed Products – only for so long as Adicet directly or indirectly owns or controls AIT; provided, however,
without limiting Adicet’s obligation under Section 2 of this Amendment, upon the sale, transfer or change of control to a third party of control of AIT, such third party thereafter shall be jointly and severally bound by the
obligations of AIT under the License Agreement, including without limitation Section 7 (“Consideration for Grant of License”) (as amended hereby) and Section 8 (“Reports; Payments; Records”) of the License
Agreement. Nothing herein shall relieve Adicet from its obligations under Section 2 of this Amendment regarding Adicet Licensed Products. Adicet additionally shall remain bound by all the terms and conditions of any sublicense agreement
with AIT. 
 4.    If a third party acquires Adicet and its Subsidiaries or Downstream Affiliates in an M&A
Transaction, then Licensed Products shall exclude all products of the acquiror or its Affiliates (other than Adicet and its Subsidiaries and Downstream Affiliates) provided that such products do not comprise or incorporate technology owned or
controlled by Adicet or its Subsidiaries or Downstream Affiliates, or by AIT or its Subsidiaries or Downstream Affiliates (including without limitation the Licensed Technology and Joint Researcher Improvements). 

5.    If a third party acquires AIT and its Subsidiaries or Downstream Affiliates in an M&A Transaction, then Licensed
Products shall exclude all products of the acquiror or its Affiliates (other than AIT and its Subsidiaries and Downstream Affiliates) provided that such products do not comprise or incorporate technology owned or controlled by Adicet or its
Subsidiaries or Downstream Affiliates, or by AIT or its Subsidiaries or Downstream Affiliates (including without limitation the Licensed Technology and Joint Researcher Improvements) and further provided that in such M&A Transaction, Adicet
shall not be relieved from its obligations under Section 2 of this Amendment regarding Adicet Licensed Products without TRDF’s written consent which shall not be unreasonably withheld. 

6.    Without limiting Adicet’s obligations under this Amendment, Adicet shall have the option to acquire and assume
from AIT all rights and obligations of Company set forth in the License Agreement with respect to all but not part of the licensed intellectual property and technology thereunder. 

7.    As of the date hereof, the License Agreement is in full force and effect, and TRDF is not aware of any facts or
circumstances that may indicate that AIT has not used Commercially Reasonable Efforts to discover or develop at least one Licensed Product. 

8.    Other than as specifically amended herein, the provisions, terms and conditions of the License Agreement shall
remain unchanged and in full force and effect. 
 9.    Nothing herein shall be construed (a) as providing Adicet
or AIT or their respective Affiliates with any ownership or license rights to any intellectual property beneficially owned by TRDF other than the intellectual property subject to the License Agreement, or (b) as providing TRDF with any
ownership or license rights to any intellectual property beneficially owned by Adicet or AIT or their respective Affiliates.
