This RETENTION INCENTIVE AGREEMENT (this “Agreement”) is made and entered into this 24th day of January, 2022 (“Effective Date”) by and between [GCP Applied Technologies, Inc.] (the “Company”) and David Campos, (the “Employee”). The Company is a party to that Agreement and Plan of Merger entered into as of December 5, 2021 pursuant to which the Company will be acquired by certain other parties to that agreement (the “Purchase Agreement”).

The parties desire to enter into this Agreement to provide the Employee with an incentive to continue Employee’s employment with the Company for a period of time through and following the date of the consummation of the transactions contemplated under the Purchase Agreement (the “Closing Date”).

Accordingly, in consideration of the mutual covenants set forth below, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the Company and the Employee agree as follows:

I.Retention Bonus. The Employee shall have an opportunity to earn a certain retention bonus (“Retention Bonus”) in accordance with the following provisions:

1.The Retention Bonus shall be payable in two (2) equal installments.

a.The first installment will be paid within sixty (60) days following the Closing Date provided the employee remains continuously actively employed by the Company from the date of this Agreement through the Closing Date.

b.The second installment will be paid within sixty (60) days following the date that is ninety (90) days following the Closing Date provided the employee remains continuously actively employed by the Company from the date of this Agreement through such date.

2.To be eligible to receive each installment of the Retention Bonus, the Employee:

a.must remain compliant with all Company policies and practices;

b.must remain compliant with all of Employee’s contractual obligations to the Company.

3.As a condition of payment of either installment of the Retention Bonus, the Employee will be required to execute and not revoke a release of claims in a form to be provided by the Company relating to all employment-related matters, excluding any claims relating to payment under this Agreement or any severance obligations.

4.In the event that the employee has not previously entered into a restrictive covenant agreement, the Employee may be required, as a condition of payment of either installment of the Retention Bonus, to execute an agreement with the Company containing post-employment restrictive covenants including, without limitation a non-compete, a non-solicitation of employees and a non-solicitation of customers for a period not to exceed 12 months post-termination.

5.If the Company terminates the Employee’s employment without Cause prior to the payment of any portion of the Retention Bonus, the Employee will be immediately entitled to payment of any unpaid portion of the Retention Bonus. Payment of the Retention Bonus upon such termination will be conditioned upon execution of a release and/or a restrictive covenant agreement as otherwise provided herein.

a.The term “Cause” used in this Agreement shall mean: (i) fraud against the Company or its affiliates; (ii) failure or any refusal to implement or undertake the lawful directives of the Chief Executive Officer, the Employee’s direct supervisor or the Company’s Board of Directors; (iii) engaging in conduct that causes injury, monetary or otherwise, to the Company or its affiliates, or that reflects adversely on the Company or its affiliates, or materially affects the Employee’s ability to perform his duties; (iv) arrest for, indictment for, or being formally charged with, the commission of a felony or commission of a crime, whether or not a felony, involving the Employee’s duties for the Company or that may reflect unfavorably on the Company or its affiliates, or bring the Employee into public disrepute or scandal; (v) theft, misappropriation, embezzlement or conversion of the assets or opportunities of the Company or its affiliates; (vi) a material breach of the terms, covenants or representations of this Agreement, and/or (vii) a material violation of Company policies.

b.Notwithstanding the foregoing, in the event the Employee has a separate written agreement with the Company that defines Cause, the definition in that separate agreement shall apply for purposes of this Agreement.

6.If the Employee terminates his or her employment with Good Reason prior to the payment of any portion of the Retention Bonus, the Employee will be immediately entitled to payment of any unpaid portion of the Retention Bonus. Payment of the Retention Bonus upon such termination will be conditioned upon execution of a release and/or a restrictive covenant agreement as otherwise provided herein.

a.The term “Good Reason” used in this Agreement shall mean the occurrence of any of the following events without the written consent of the Employee: (i) a material reduction by the Company in the Employee’s Base Salary (other than an inadvertent reduction in Base Salary not occurring in bad faith and that is remedied by the Company within 45 days after receipt of notice thereof given by the Employee); (ii) relocation, beyond thirty five (35) miles from the office used by the Employee as the Employee’s principal business location in connection with the provision of services to the Company; (iii) a material reduction in the Employee’s duties; or (iv) the material breach by the Company of any provision of this Agreement.

b.Notwithstanding the foregoing, in the event the Employee has a separate written agreement with the Company that defines Good Reason, the definition in that separate agreement shall apply for the purposes of this Agreement.

II.Term of Agreement. In the event that the transaction is not consummated or the Closing Date does not occur prior to December 5, 2022, this Agreement will terminate, and no retention payments will be due. Notwithstanding the foregoing, the Company in its discretion may extend this Agreement through March 5, 2023 in the Company’s sole discretion and such extension may be evidenced by notice to the employee by any reasonable means determined by the Company.

III.Non-Disclosure. Except as may be required by law, neither the Employee nor the Company shall disclose the financial terms of this Agreement to persons not involved in the operation of the Company and the parties shall disclose the financial terms of the Agreement to those involved in the operation of the Company only as needed to implement the terms of the Agreement or carry out the operations of the Company. The above notwithstanding, the Agreement may be disclosed to: (i) the parties’ attorneys,

accountants, financial or tax advisors, and any potential lenders, investors in or purchasers of the Company, provided such persons agree not to disclose such terms of the Agreement further; and (ii) members of the Employee’s immediate family, provided such family members agree not to reveal the terms of the Agreement further.

IV.Successors and Assigns, No Third Party Beneficiaries. The rights and obligations of the Company under this Agreement shall be binding on and inure to the benefit of the Company, its successors and permitted assigns. The rights and obligations of the Employee under this Agreement shall be binding on and inure to the benefit of the heirs and legal representatives of the Employee. Neither party may assign this Agreement without the prior written consent of the other, except that the Company may assign the Agreement to an affiliate of the Company, or to any entity acquiring all or substantially all of the assets or the business of the Company without obtaining the Employee’s prior consent. This Agreement does not create, and shall not be construed as creating any rights enforceable by any person not a party to this Agreement.

V.Waiver or Modification. Any waiver by either party of a breach of any provision of this Agreement shall not operate as, or be construed to be, a waiver of any other breach of such provision of this Agreement. The failure of either party to insist on strict adherence to any term of this Agreement on one or more occasions shall not be considered a waiver or deprive either party of the right thereafter to insist on strict adherence to that term or any other term of this Agreement. Neither this Agreement nor any part of it may be waived, changed or terminated orally, and any waiver, amendment or modification must be in writing signed by the Employee and the Company.
