Form of Restricted Stock Unit Award Agreement for Non-Employee Directors

100% of the RSUs shall vest on the earlier of (a) the first anniversary of the Grant Date and (b) the date of the Company’s next annual meeting of stockholders following the Grant Date (the “Vesting Date”).

Upon a Change in Control, any outstanding, unvested RSUs will immediately vest as of the date of such Change in Control.

No later than 30 days after the Vesting Date (or, if earlier, the date of a Change in Control), AZEK will issue to the Grantee one share of Class A Common Stock, par value $0.001 per share (each, a “Share”), of AZEK for each vested RSU, subject to applicable tax withholding as provided in Section 3.2 of the Plan (the date on which the Shares are so issued, the “Delivery Date”).

On each Delivery Date, AZEK will pay to the Grantee a cash

amount equal to the product of (x) all cash dividends or other distributions (other than cash dividends or other distributions pursuant to which the RSUs were adjusted pursuant to Section 1.6.3 of the Plan), if any, paid on a Share from the Grant Date to the applicable Delivery Date and (y) the number of Shares delivered to the Grantee on the applicable Delivery Date (including for this purpose any Shares which would have been delivered on the applicable Delivery Date but for being withheld to satisfy tax withholding obligations). The Grantee will have no voting rights with respect to any of the Shares underlying any RSUs until such Shares are issued and delivered to the Grantee and the Grantee’s name is entered as a stockholder of record on the books of AZEK.

Payments under this Award Agreement are intended to be exempt from or comply with Section 409A of the Internal Revenue Code (“Section 409A”) to the extent applicable, and this Award Agreement shall be administered accordingly. Notwithstanding anything to the contrary contained in this Award Agreement, to the extent that any payment under this Award Agreement is determined by AZEK to constitute “non-qualified deferred compensation” subject to Section 409A and is payable to the Grantee by reason of termination of the Grantee’s service as a non-employee Director, then (a) such payment shall be made to the Grantee only upon a “separation from service” as defined for purposes of Section 409A under applicable regulations and (b) if the Grantee is a “specified employee” (within the meaning of Section 409A and as determined by AZEK), such payment shall not be made before the date that is six months after the date of the Grantee’s separation from service (or the Grantee’s earlier death). Each payment under this Award Agreement shall be treated as a separate payment for purposes of Section 409A.

The Grantee is advised to review with his/her own tax advisors the

federal, state and local tax consequences of receiving the RSUs. The Grantee hereby represents to AZEK that he/she is relying solely on such advisors and not on any statements or representations of AZEK, its Affiliates or any of their respective agents. If, in connection with the RSUs, AZEK is required to withhold any amounts by reason of any federal, state or local tax, such withholding shall be effected in accordance with Section 3.2 of the Plan. If the RSUs vest prior to payment, then the Grantee agrees to cooperate with AZEK to satisfy any tax withholding obligations, in such manner as determined by the Compensation Committee (“Committee”) in its sole discretion.

The Grantee may not sell, exchange, transfer, assign, pledge, hypothecate or otherwise encumber the RSUs or the Shares underlying the RSUs, other than to the extent provided in Section 3.5 of the Plan.

The Committee reserves the right at any time to amend the terms and conditions set forth in this Award Agreement, except that the Committee shall not make any amendment in a manner unfavorable to the Grantee (other than if immaterial), without the Grantee’s consent. Any amendment of this Award Agreement shall be in writing and signed by an authorized member of the Committee or a person or persons designated by the Committee.

This Award Agreement shall be deemed to be made under, and in all respects be interpreted, construed and governed by and in accordance with, the laws of the State of Delaware without regard to conflict of law principles.
