NOW, THEREFORE, in consideration of the foregoing premises, the parties hereto hereby agree as follows:

1.Defined Terms. All terms not defined herein shall have the meanings ascribed to such terms in the Agreement.

2.Employment. The Agreement is hereby amended such that Sections [7 through 9]4[5 through 7]5, inclusive, thereof are hereby terminated and of no further force or effect. Upon such termination, none of the Company, Employer, or Executive shall have any obligation or liability under or in respect of such sections except as may be set forth in that certain Employment Agreement, dated as of [●], by and among Executive, [Employer]6, and Maravai LifeSciences Holdings, Inc., a Delaware corporation.

4.Future Amendments. The Agreement is hereby amended such that the provisions of the Agreement may be amended and waived by the prior written consent of only the Company and Executive.

5.Applicable Law. This Amendment shall be construed and enforced in accordance with the laws of the State of Delaware, without regard to such state’s laws concerning conflicts

of laws. In the event of a conflict between any provisions of this Amendment and any nonmandatory provisions of the Delaware Act, the provision of this Amendment shall control and take precedence.

If any provision of this Amendment is held to be illegal, void, voidable, invalid, nonbinding or unenforceable in its entirety or partially or as to any party, for any reason, and if such provision cannot be changed consistent with the intent of the parties hereto to make it fully legal, valid, binding and enforceable, then such provision shall be stricken from this Amendment, and the remaining provisions of this Amendment shall not in any way be affected or impaired, but shall remain in full force and effect.

7.Counterparts. This Amendment may be executed in any number of counterparts, each of which shall be deemed an original, and all of which taken together shall constitute one and the same instrument.
