survive and not be affected by the death, incapacity, mental illness or insanity of such Equityholder, as applicable) until the termination of this Agreement and shall not be terminated by operation of legal requirements or upon the occurrence of
any other event other than the termination of this Agreement with respect to such Equityholder pursuant to Section 4.2 (and shall be terminated and revoked upon such termination). Each Equityholder authorizes such attorney and proxy to
substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the secretary of CST. Each Equityholder hereby affirms that the proxy set forth in this Section 1.4

execute and deliver this Agreement and to perform his or her obligations hereunder. If such Equityholder is not an individual, the execution, delivery and performance by such Equityholder of this
Agreement and the consummation by such Equityholder of the transactions contemplated hereby have been duly authorized by all necessary action on the part of such Equityholder. 

Section 2.3 Due Execution and Delivery; Binding Agreement. This Agreement has been duly executed and delivered by such
Equityholder and constitutes a valid and legally binding obligation of such Equityholder, enforceable against such Equityholder in accordance with its terms, subject to the effects of bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium and other similar legal requirements relating to or affecting creditors’ rights generally and general equitable principles (whether considered in a proceeding in equity or at law). 

Section 2.4 No Violation 

(a) The execution and delivery of this Agreement by such Equityholder does not, and the performance by such Equityholder of such
Equityholder’s obligations hereunder will not, (i) if such Equityholder is not an individual, contravene, conflict with, or result in any violation or breach of any provision of its organizational documents, (ii) assuming compliance
with Section 2.4(b), contravene, conflict with or result in a violation or breach of any provision of applicable legal requirements or order of any governmental entity with competent jurisdiction or (iii) constitute a default, or an

Equityholder, except, in the case of clauses (ii) and (iii), as would not reasonably be expected to impair in any material respect the ability of such Equityholder to perform his, her or its obligations hereunder or to consummate the
transactions contemplated hereby on a timely basis. 
 (b) No consent, approval, order, authorization or permit of, or registration,
declaration or filing with or notification to, any governmental entity or any other Person is required by or with respect to such Equityholder in connection with the execution and delivery of this Agreement by such Equityholder or the performance by
