that were incurred but not reimbursed as of the date of death and for which appropriate documentation as required be paragraph 7(b) has been submitted to the Company. If, prior to the date of his death, Executive had earned the right to receive any

termination not occurred. 
 c. Termination for Just Cause or Permanent Disability. In the event the
Executive is terminated by the Company for Just Cause or upon Permanent Disability (as those terms are defined below), the Company’s obligation to make payments hereunder shall cease upon such termination, and the Company shall have no

Effective Date, the Company’s Board of Directors will review the financial condition and prospects of the Company in order to determine whether or not it would be financially prudent for the Company to offer to modify this Agreement to make a
termination for Permanent Disability subject to Section 9(d) of this Agreement rather than this Section 9(c) so that a Severance Payment, as defined in Section 9(d), would be payable in the event of a termination of the employment of
the Executive based on Permanent Disability. 
 d. Termination by the Company without Just Cause. Company will have
the unilateral right to terminate Executive’s employment with Company at any time without Just Cause. In the event Executive is terminated without Just Cause other than upon Permanent Disability or resigns for Good Reason (as defined below),

	 	 (d)
	 Tax Gross-Up Payment. In the event the Executive elects to be paid all or any portion of a Bonus in shares of the Company’s common

Section 414(p) of the Internal Revenue Code of 1986, as amended, (the Code”). Payment pursuant to such domestic relations order may be made as soon as administratively feasible following determination by the Administrator, in its sole
discretion, that said order satisfies the requirements for a valid domestic relations order that is consistent with the terms and payment provided under the Plan. 



 

	 	 (b)
	 Tax Requirements. All payments made pursuant to the Plan shall be subject to all applicable taxes required by U.S. federal, state or local

retained in the employ of Company or any of its affiliates, and the right of Company and any such affiliate to dismiss the Executive or to terminate any arrangement pursuant to which the Executive provides services to Company, with or without cause,
is specifically reserved.

 3 









	 	 (e)
	 Other Compensation Arrangements. Nothing contained in the Plan shall prevent Company from adopting or continuing in effect other
compensation arrangements, which arrangements may be either generally applicable or applicable only in specific cases. 


  

	 	 (f)
	 Governing Law. The validity, construction and effect of the Plan and any rules and regulations relating to the Plan shall be determined in
accordance with federal laws and the laws of the State of California, without regard to the State of California’s conflicts of law rules. 


  

	 	 (g)
	 No Trust. The Plan shall not create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between
Company and any individual. To the extent that the Executive acquires a right to receive payments from Company with respect to a Bonus, such right shall be no greater than the right of any unsecured general creditor of Company.



  

	 	 (h)
	 Section 409A of the Code. The Plan is intended to be exempt from Section 409A of the Internal Revenue Code of 1986 under the
short-term deferral rule. The Plan shall be administered and interpreted to maximize the short-term deferral rule and any payments made pursuant to that rule shall not be aggregated with any other payment. The Executive shall not, directly or
indirectly, designate the taxable year that any payment will be made under the Plan. 


 To record the adoption of this
Aduro BioTech Performance Bonus Plan, Company has caused its authorized officer to execute this Plan on this 26th day of February, 2010.
