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 or Vesuvius Group S.A. and its or their subsidiaries.

| | ---- | ---------------------------------------------



In the event of the termination by Vesuvius Group S.A. or the Employee of the Belgian Service Agreement in accordance with the law of 3 July 1978
(Belgium), this Agreement shall, subject to Section 3(c) below, automatically terminate at the same time.



|(b) | Effect of Termination.
|--- | ----------------------



In the event of termination, if the Employee holds a position of officer or director of Cookson Group plc or the Company or any subsidiary of the Company
or as trustee of any pension fund or other entity associated with the Company or any subsidiary of the Company, the Employee shall be deemed to have resigned such position as officer or director or trustee as of the effective date of termination, or
as of the date the Company or the Employee notifies the other that the Employees employment will be terminated, whichever is sooner. By entering into this Agreement, the Employee irrevocably appoints the Company to act on his behalf to execute
any document and do anything in his name for the purpose of effecting such resignations.

termination under Section 3(a)(ii) above in circumstances of serious misconduct (motif grave) or force majeure), no severance payment is payable by the Company.
| | --- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | ---- | -----------------------------------------------------------------------------------------------------



| | (A) | the value of the Employees Base Salary (as at the rate last set before the date of termination); and
| | --- | -----------------------------------------------------------------------------------------------------

|(d) | Payment of Severance Payment
|--- | ----------------------------



| | (i) | One half the payment calculated under Section 3(c) above shall be paid by the Company in a lump sum (less applicable withholding taxes and other customary employee deductions),
within 30 days of the date of termination. The remaining sum will be paid in equal monthly instalments, subject to applicable federal, state and local tax withholdings, commencing in the Company payroll period after the month in which the midpoint
of the Required Notice Period falls, for the remainder of the Required Notice Period. If the Employee has commenced alternative employment before the payroll date in any month in which such a payment would otherwise be made, the gross base salary
earned by the Employee in that month shall be deducted from the gross monthly instalment. The Employee shall notify the Board of Directors promptly upon obtaining new employment, which notice shall include the Employees start date and gross
monthly base salary. The Company undertakes for itself and its Directors to keep the gross monthly base salary confidential, subject to legal reporting requirements.
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | The Company will deduct from any payment required under Section 3(d)(i) above any and all sums paid to the Employee by Vesuvius Group S.A. following termination or the service of
notice of termination of the Belgian Service Agreement. Such sums will be deducted from sums payable under this Agreement in the order in which they fall due for payment.
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|(e) | It is a pre-condition of any payment under Section 3(d) that the Employee shall have entered into such further agreements as the Company may require for the sole purpose of
releasing Cookson Group plc or the Company or Vesuvius Group S.A. or any of its or their subsidiaries or any of their officers and/or employees from any claims the Employee may have arising out of the employment relationship or its termination in
any jurisdiction, except for claims relating to workers compensation and or unemployment compensation, claims arising after the effective date of the said release agreements and claims relating to any breach of the said release agreements. The
Company acknowledges that the said release agreements in compromise or settlement of any claims shall be in compliance with the requirements for the valid waiver of said claims as set forth in the Age Discrimination in Employment Act, 29 U.S.C.
sec.621 et seq.

Inventions) which he may thereafter, alone or in conjunction with others, during or outside normal working hours, conceive, make, acquire or suggest at any time which relate to the products, processes, work, research, or other activities
of the Company or any of its subsidiaries or affiliates. Any and all Inventions which are of a proprietary nature and which the Employee may conceive, acquire or suggest, either alone or in conjunction with others, during his employment with the
Company (whether during or outside normal working hours) relating to or in any way pertaining to or connected with the Companys business, shall be the sole and exclusive property of the Company or its designee and the Employee, whenever
requested to do so by the Company, shall without further compensation or consideration properly execute any and all applications, assignments or other documents which the Company or its designee shall deem necessary in order to apply for and obtain
Letters Patent of the United States and/or comparable rights afforded by foreign countries for the Inventions, or in order to assign and convey to the Company or its designee the sole and exclusive right, title and any interest in and to the
Inventions. This obligation shall continue beyond the termination of this Agreement with respect to Inventions conceived or made by the Employee during the term of his employment by the Company, and shall be binding upon his assigns, executors,
administrators and other legal representatives.

may realize as a result of, growing out of, or in connection with, any such violation. These remedies shall be in addition to, and not in limitation of, any injunctive relief or other rights or remedies to which the Company is or may be entitled at
law, in equity, or under this Agreement.
