This RESTRICTED STOCK UNIT AGREEMENT (the “Agreement”) is made as of     
                     (the “Grant Date”) between ADPT CORPORATION, a Delaware corporation (the “Company”), and
                                 (the “Grantee”). Capitalized terms used

 A.
The Board of Directors (the “Board”) and shareholders of the Company previously adopted the Plan.

 In consideration of the foregoing, the parties hereto hereby agree as follows:

  

	 	1.	Grant of Restricted Stock Unit. The Company hereby grants to the Grantee a Restricted Stock Unit covering
             Shares (the “RSU”) as of the Grant Date. 

  

	 	2.	Settlement of RSU. Upon each vesting of all or a specified portion of the RSU, the Company shall transfer to the Grantee (or such other person entitled to receive
payment pursuant to this Agreement and the Plan) the number of Shares covered by the RSU vesting on each vesting date. 

  

	 	3.	Vesting. Except as may be otherwise provided in the Plan and this Agreement, the RSU shall vest as follows: 100% of the Shares covered by the RSU shall vest on the
earlier of (i)                      or (ii) the date the Grantee ceases to be a member of the Board for any reason, including as a
result of the Grantee’s death or Disability. Vesting of the RSU shall be subject to acceleration as provided in the Plan. 

  

	 	4.	Term of RSU. The term of the RSU commences on the Grant Date and expires upon the date the RSUs vest and the Shares are settled and issued. 


 

	 	5.	Non-Transferability of RSU. The RSU may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may not be subject to
execution, attachment or similar process. In any event, the RSU may not be transferred in exchange for consideration. 

  

	 	6.	No Rights as Director or Shareholder. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a Parent or Subsidiary
of the Company, to terminate Grantee’s membership on the Board. Grantee shall not have any rights as a shareholder with respect to any Shares by virtue of the holding of the RSU. 


 

	 	7.	Entire Agreement; Governing Law. The Plan is incorporated herein by reference. The Plan, and this Agreement constitute the entire agreement of the parties
with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and Grantee with respect to the subject matter hereof, and may not be modified adversely to Grantee’s interest except
by means of a writing signed by the Company and Grantee. This agreement is governed by California law except for that body of law pertaining to conflict of laws. 


 

	 	8.	Enforcement of Rights. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing
and signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party.

accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 









	 	10.	Notices. Any notice to be given under the terms of the Plan shall be addressed to the Company in care of its principal office, and any notice to be given to Grantee
