AMENDMENT NO. 79

to the BULK DRUG SUBSTANCE ORDERING AGREEMENT

EFFECTIVE 5 FEBRUARY 2015

between

LONZA SALES AG

and

ELUSYS THERAPEUTICS, INC.

THIS AMENDMENT 79 (this “Amendment”) is made the 30^th day of September 2022 (“Amendment Effective Date”)

BETWEEN

1.	LONZA SALES AG, of Muenchensteinerstrasse 38, Ch-4002 Basel, Switzerland (“Lonza”) and

2.	ELUSYS THERAPEUTICS, INC., of 4 Century Drive, Suite 260, Parsippany, NJ 07054, USA (“Customer” or “Elusys”).

WHEREAS

A.	Customer and Lonza entered into that certain Anthim Bulk Drug Substance Ordering Agreement dated 5 February 2015 (as amended, the “Agreement”), under which Lonza is required to perform Services relating to the Cell Line and Bulk Drug Substance; and

B.	The Parties wish to make certain changes to the Agreement to capture the transfer of the manufacturing process to the Lonza Portsmouth, NH 6,000L scale bioreactor suite, and to manufacture agreed Batches.

NOW THEREFORE it is agreed hereby by the parties as follows:

Capitalised terms used but not otherwise defined in this Amendment refer to those definitions in the Agreement.

Lonza will perform the additional Services in Stages 201-231 inclusive, as more fully set out in the Schedule below, provided however:

the number of cGMP Pre-Approval Inspection (PAI) Batches at 6,000 Liter Scale as set out in Stage 228 may be reduced should the Customer receive regulatory agency approval to reduce the number of Batches required to demonstrate the Process upon inspection of the Lonza Portsmouth facility. Any PAI Batch campaign of less than six [*****] batches will be subject to a Batch price [*****]

the [*****] commercial Batches referred to in Stage 229 are subject to Customer [*****] for additional Batches. Upon [*****] notice to Lonza, the Parties will proceed regarding such [*****] commercial Batches in Stage 229 in accordance with Section 5 of the Agreement. [*****], then (a) Customer is not liable for the Batches in Stage 229, and (b) Lonza is not obliged to reserve any capacity for the Customer. Should [*****] additional Batches require additional production of Batches above the [*****] Batches listed in Stage 229, Customer shall submit this additional demand via the forecasting mechanism in Section 5 of the Ordering Agreement for Lonza review. Elusys is under no obligation to order Batches each calendar year beyond those Batches defined in Stage 229. The Batch campaign size in Stage 229 shall not be less than [*****] Batches per year subject to the Forecasting mechanism set forth in the Ordering Agreement.

Section 5.6 of the Agreement shall be deleted in its entirety and replaced with the following:

“5.6

Purchase Obligation. Customer is not obliged to purchase exclusively from Lonza however, Customer does have the purchase obligations for Stages 201-231 as referred to in Section 2 above in this Amendment 79”

Save as herein provided, all other terms and conditions of the Agreement shall remain in full force and effect and are hereby ratified and confirmed in all respects. For further clarity, nothing in this Amendment 79 shall change the obligations of either Party in respect of 6K Batches except as set forth above, and all provisions and obligations (including the forecasting, ordering and cancellation provisions) in respect thereof shall continue.

This Amendment may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. Delivery of executed copies (including by PDF) of this Amendment or counterparts thereof by facsimile, email or other electronic means will have the same legal validity as delivery of ink-signed copies. The Agreement, as previously amended and as amended by this Amendment, constitutes the entire agreement between the parties with respect to its subject and supersedes all contemporaneous and prior discussions and negotiations between the parties.

IN WITNESS WHEREOF, the parties have caused this Amendment No. 79 to be executed by their representatives thereunto duly authorised as of the day and year first written.
