activity shall be engaged in for pecuniary gain, without the prior written approval of the Board of Directors, which consent shall not be unreasonably withheld. If such consent is given, the Employee shall be obliged to disclose to the Company any
compensation paid to him on account of such activity. The foregoing limitation shall not be construed as prohibiting the Employee from making personal investments in such form or manner as will neither require the Employees services in the
operation or affairs of the companies or enterprises in which such investments are made nor violate the terms of Section 5. The Employee further agrees that he will not, directly or indirectly, engage or participate in any activities at any time
during the term of this Agreement in conflict with the best interests of Cookson Group plc, or of the Company and its subsidiaries.

by the Employee, constitute termination of this Agreement other than By the Company for Cause as specified in Section 3(a)(iv).
