Form of Grant Notice for 2018 Stock Incentive Plan Restricted Stock Unit Award

Forterra, Inc. (the “Company”), has granted to the Participant named in the Grant Notice provided to said Participant herewith (the “Grant Notice”) an award of a number of restricted stock units (the “Award” or the “Restricted Stock Units”) with each Restricted Stock Unit representing the right to receive one share of the Company’s common stock, par value $0.001 (the “Common Stock”) specified in the Grant Notice. The Award is subject to the conditions set forth in the Grant Notice, these Standard Terms and Conditions, and the Plan, each as amended from time to time. For purposes of these Standard Terms and Conditions and the Grant Notice, any reference to the Company shall include a reference to any Subsidiary.

The Award shall not be vested as of the Grant Date set forth in the Grant Notice and shall be forfeitable unless and until otherwise vested pursuant to the terms of the Grant Notice and these Standard Terms and Conditions. After the Grant Date, subject to termination or acceleration as provided in these Standard Terms and Conditions and the Plan, the Award shall become vested as described in the Grant Notice with respect to that number of Restricted Stock Units as set forth in the Grant Notice. Restricted Stock Units that have vested and are no longer subject to forfeiture are referred to herein as “Vested RSUs.” Restricted Stock Units awarded hereunder that are not vested and remain subject to forfeiture are referred to herein as “Unvested RSUs.” Notwithstanding anything contained in these Standard Terms and Conditions to the contrary, upon a Participant’s Termination of Employment due to Participant’s death, Disability or Retirement, or upon a Termination of Employment by the Company without Cause within 24 months following the occurrence of a Change in Control, all Unvested RSUs shall become vested on the date of such Termination of Employment. For purposes of this Award Agreement, “Retirement” means (i) for employees, retirement from active employment with the Company and its Subsidiaries at or after age 60 with 10 years of service recognized by the Company, or (ii) for non­employee directors: retirement from active service with the Company after having served as a non­employee director for at least an aggregate of three full years (excluding any service while a full­time employee of the Company), and any determination of the Compensation Committee of the Company’s Board of Directors as to an individual’s Retirement shall be conclusive on all parties. Upon a Participant’s Termination of Employment for any other reason, including a Termination of Employment by the Company without Cause that occurs prior to the occurrence of a Change in Control, any then Unvested RSUs held by the Participant shall be forfeited and canceled as of the date of such Termination of Employment. For purposes hereof, a Change in Control (as defined in the Plan) will not be deemed to occur until such date as the Company is no longer a controlled company of Lone Star Fund IX (U.S.), L.P.

Participant shall not be, nor have any of the rights or privileges of, a stockholder of the Company in respect of any RSUs unless and until shares of Common Stock settled for such RSUs shall have been issued by the Company to Participant (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company). Notwithstanding the foregoing, from and after the Grant Date and until the earlier of (a) the time when the RSUs become nonforfeitable and payable in accordance with the terms hereof or (b) the time when the Participant’s right to receive Common Stock upon payment of RSUs is forfeited, on the date that the Company pays a cash dividend (if any) to holders of Common Stock generally, the Participant shall be entitled to a number of additional whole RSUs determined by dividing (i) the product of (A) the dollar amount of the cash dividend paid per share of Common Stock on such date and (B) the total number of RSUs (including dividend equivalents paid thereon) previously credited to the Participant as of such date, by (ii) the Fair Market Value per share of Common Stock on such date. Such dividend equivalents (if any) shall be subject to the same terms and conditions and shall be settled or forfeited in the same manner and at the same time as the RSUs to which the dividend equivalents were credited.

The Company may impose such restrictions, conditions or limitations as it determines appropriate as to the timing and manner of any resales by the Participant or other subsequent transfers by the Participant of any shares of Common Stock issued pursuant to Vested RSUs, including without limitation (a) restrictions under an insider trading policy, (b) restrictions designed to delay and/or coordinate the timing and manner of sales by Participant and other holders and (c) restrictions as to the use of a specified brokerage firm for such resales or other transfers.

To the extent required by applicable federal, state, local or foreign law, the Participant shall make arrangements satisfactory to the Company for the satisfaction of any withholding tax obligations that arise by reason of the grant or vesting of the RSUs. The Company shall not be required to issue shares or to recognize the disposition of such shares until such obligations are satisfied.

The Participant understands, acknowledges and agrees that, except as otherwise provided in the Plan or as permitted by the Committee, the Award may not be sold, assigned, transferred, pledged or otherwise directly or indirectly encumbered or disposed of other than by will or the laws of descent and distribution.

The Grant Notice, these Standard Terms and Conditions and the Plan constitute the entire understanding between the Participant and the Company regarding the Award. Any prior agreements, commitments or negotiations concerning the Award are superseded.

Neither the Participant (individually or as a member of a group) nor any beneficiary or other person claiming under or through the Participant shall have any right, title, interest, or privilege in or to any shares of Common Stock allocated or reserved for the purpose of the Plan or subject to the Grant Notice or these Standard Terms and Conditions except as to such shares of Common

Stock, if any, as shall have been issued to such person in connection with the Award. Nothing in the Plan, in the Grant Notice, these Standard Terms and Conditions or any other instrument executed pursuant to the Plan shall confer upon the Participant any right to continue in the Company’s employ or service nor limit in any way the Company’s right to terminate the Participant’s employment at any time for any reason.

(a)In the event that any provision of these Standard Terms and Conditions is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction, such provision shall be reformed, if possible, to the extent necessary to render it legal, valid and enforceable, or otherwise deleted, and the remainder of these Standard Terms and Conditions shall not be affected except to the extent necessary to reform or delete such illegal, invalid or unenforceable provision.

(b)The headings preceding the text of the sections hereof are inserted solely for convenience of reference, and shall not constitute a part of these Standard Terms and Conditions, nor shall they affect its meaning, construction or effect.

(c)These Standard Terms and Conditions shall inure to the benefit of and be binding upon the parties hereto and their respective permitted heirs, beneficiaries, successors and assigns.

(d)These Standard Terms and Conditions shall be construed in accordance with and governed by the laws of the State of Delaware, without regard to principles of conflicts of law.

(e)In the event of any conflict between the Grant Notice, these Standard Terms and Conditions and the Plan, the Grant Notice and these Standard Terms and Conditions shall control. In the event of any conflict between the Grant Notice and these Standard Terms and Conditions, the Grant Notice shall control.

(f)All questions arising under the Plan or under these Standard Terms and Conditions shall be decided by the Committee in its total and absolute discretion.

By executing the Grant Notice, the Participant hereby consents to the delivery of information (including, without limitation, information required to be delivered to the Participant pursuant to applicable securities laws) regarding the Company and the Subsidiaries, the Plan, and the Restricted Stock Units via Company web site or other electronic delivery.
