of the Participant’s employment so long as the Participant continues to be an employee of the Company or any of its Subsidiaries.
Whether (and the circumstances under which) employment has been terminated and the determination of the date of Termination for
the purposes of this Agreement shall be determined by the Committee (or, with respect to any Participant who is not a director
or “officer” as defined under Rule 16a-1(f) under the Exchange Act, its designee, whose good faith determination shall
be final, binding, and conclusive; provided, that such designee may not make any such determination with respect to the

distributions or other rights in respect of such share of Common Stock for which the record date is prior to the date upon which
Participant shall become the holder of record or the beneficial owner thereof.

 

8.                 
Tax Withholding. The provisions of Section 15(d) of the Plan are incorporated herein by reference and made a
part hereof.

 

9.                 
Restrictive Covenants. Participant acknowledges and recognizes the highly competitive nature of the businesses

Covenants”). For the avoidance of doubt, the Restrictive Covenants contained in this Agreement are in addition to, and
not in lieu of, any other restrictive covenants or similar covenants or agreements between Participant and the Company or any of

10.             
Repayment of Proceeds; Clawback Policy. If a Restrictive Covenant Violation occurs or the Company discovers after
a Termination that grounds existed for Cause at the time thereof, then Participant shall be required, in addition to any other
remedy available (on a non-exclusive basis), to pay to the Company, within ten (10) business days following the Company’s
request to Participant therefor, an amount equal to the aggregate after-tax proceeds (taking into account all amounts of tax that
would be recoverable upon a claim of loss for payment of such proceeds in the year of repayment) Participant received upon the
sale or other disposition of, or distributions in respect of, the Restricted Stock Units and any Shares issued in respect thereof.
Any reference in this Agreement to grounds existing for a Termination with Cause shall be determined without regard to any notice
period, cure period, or other procedural delay or event required prior to finding of or Termination with Cause. The Restricted
Stock Units and all proceeds of the Restricted Stock Units shall be subject to the Company’s clawback policy, as in effect
from time to time, to the extent Participant is a director or “officer” as defined under Rule 16a-1(f) of the Exchange
Act.

 

11.             
No Right to Continued Employment. Neither the Plan nor this Agreement nor the Participant’s receipt of
the Restricted Stock Units hereunder shall impose any obligation on the Company or any Affiliate to continue the employment or
engagement of the Participant. Further, the Company or any Affiliate (as applicable) may at any time terminate the employment or
engagement of such Participant, free from any liability or claim under the Plan or this Agreement, except as otherwise expressly
provided herein.

or any other participant in the Plan.

16.             
Governing Law; Venue; Language. This Agreement shall be governed by and construed in accordance with the laws
of the State of Delaware. Any suit, action, or proceeding with respect to this Agreement, or any judgment entered by any court
in respect of any thereof, shall be brought in any court of competent jurisdiction in the State of Delaware, and each of the Participant
and the Company each hereby irrevocably waives (a) any objections which it may now or hereafter have to the laying of the venue
of any suit, action, or proceeding arising out of or relating to this Agreement brought in any court of competent jurisdiction
in the State of Delaware, (b) any claim that any such suit, action, or proceeding brought in any such court has been brought in
any inconvenient forum, and (c) any right to a jury trial.

 

17.             
Award Subject to Plan. By entering into this Agreement, the Participant agrees and acknowledges that the Participant
has received and read a copy of the Plan. The Restricted Stock Units granted hereunder are subject to the Plan. The terms and provisions
of the Plan, as it may be amended from time to time, are hereby incorporated herein by reference. In the event of a conflict between
any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of this Agreement
will govern and prevail.

 

18.             
Severability. Should any provision of this Agreement be held by a court of competent jurisdiction to be unenforceable
or invalid for any reason, the remaining provisions of this Agreement shall not be affected by such holding and shall continue
in full force in accordance with their terms.

 

19.             
Successors in Interest. Any successor to the Company shall have the benefits of the Company under, and be entitled
to enforce, this Agreement. Likewise, the Participant’s legal representative shall have the benefits of Participant under,
and be entitled to enforce, this Agreement. All obligations imposed upon the Participant and all rights granted to the Company
under this Agreement shall be final, binding, and conclusive upon the Participant’s heirs, executors, administrators, and
successors.

 

20.             
Data Privacy Consent. The Participant hereby explicitly and unambiguously consents to the collection, use, and
transfer, in electronic or other form, of the Participant’s personal data as described in this Agreement and any other Restricted
Stock Unit grant materials by and among, as applicable, the Participant’s employer or contracting party (the “Employer”)
and the Company for the exclusive purpose of implementing, administering, and managing the Participant’s participation in
the Plan. The Participant understands that the Company may hold certain personal information about the Participant, including,
but not limited to, the Participant’s name, home address, and telephone number, work location and phone number, date of birth,
social insurance number, or other identification number, salary, nationality, job title, hire date, any shares of stock or directorships
held in the Company, details of all awards or any other entitlement to shares awarded, cancelled, exercised, vested, unvested,
or outstanding in the Participant’s favor, for the purpose of implementing, administering, and managing the Plan (“Personal
Data”). The Participant understands that Personal Data may be transferred to any third parties assisting in the implementation,
administration and management of the Plan, now or in the future, that these recipients may be located in the Participant’s
country or elsewhere, and that the recipient’s country may have different data privacy laws and protections than the Participant’s
country. The Participant understands that the Participant may request a list with the names and addresses of any potential recipients
of the Personal Data by contacting the Company’s Chief Legal Officer. The Participant authorizes the recipients to receive,
possess, use, retain and transfer the Personal Data, in electronic or other form, for the purposes of implementing, administering
and managing the Participant’s participation in the Plan. The Participant understands that Personal Data will be held only
as long as is necessary to implement, administer and manage the Participant’s participation in the Plan. The Participant
understands that the Participant may, at any time, view Personal Data, request additional information about the storage and processing
of Personal Data, require any necessary amendments to Personal Data or refuse or withdraw the consents herein, in any case without
cost, by contacting in writing the Company’s Chief Legal Officer. Further, the Participant understands that the Participant
is providing the consents herein on a purely voluntary basis. If the Participant does not consent, or if the Participant later
seeks to revoke the Participant’s consent, the Participant’s employment status or service and career with the Employer
will not be adversely affected; the only consequence of the Participant’s refusing or withdrawing the Participant’s
consent is that the Company would not be able to grant Restricted Stock Units or other equity awards to the Participant or administer
or maintain such awards. Therefore, the Participant understands that refusing or withdrawing the Participant’s consent may
affect the Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s
refusal to consent or withdrawal of consent, the Participant understands that the Participant may contact the Company’s Chief
Legal Officer.

21.             
Limitation on Rights; No Right to Future Grants; Extraordinary Item of Compensation. By accepting this Agreement
and the grant of the Restricted Stock Units evidenced hereby, the Participant expressly acknowledges that: (a) the Plan is
discretionary in nature and may be suspended or terminated by the Company at any time; (b) the grant of the Restricted Stock
Units is a one-time benefit that does not create any contractual or other right to receive future grants of restricted stock units,
or benefits in lieu of restricted stock units; (c) all determinations with respect to future restricted stock unit grants,
if any, including the grant date and the number of Shares granted, will be at the sole discretion of the Company; (d) the
Participant’s participation in the Plan is voluntary; (e) the value of the Restricted Stock Units is an extraordinary
item of compensation that is outside the scope of the Participant’s employment contract, if any, and nothing can or must
automatically be inferred from such employment contract or its consequences; (f) Restricted Stock Units are not part of normal
or expected compensation for any purpose and are not to be used for calculating any severance, resignation, redundancy, end of
service payments, bonuses, long-service awards, pension or retirement benefits or similar payments, the Participant waives any
claim on such basis and, for the avoidance of doubt, the Restricted Stock Units shall not constitute an “acquired right”
under the applicable law of any jurisdiction; (g) the value of Shares received upon settlement of the Restricted Stock Units may
increase or decrease in value; and (h) the future value of the underlying Shares is unknown and cannot be predicted with certainty.
In addition, the Participant understands, acknowledges and agrees that the Participant will have no rights to compensation or damages
related to Restricted Stock Unit proceeds in consequence of the termination of the Participant’s employment for any reason
whatsoever and whether or not in breach of contract.

 

22.             
Award Administrator. The Company may from time to time designate a third party (an “Award Administrator”)
to assist the Company in the implementation, administration, and management of the Plan and any Restricted Stock Units granted
thereunder, including by sending Award Notices on behalf of the Company to Participants, and by facilitating through electronic
means acceptance of this Agreement by Participants.

24.             
Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents
related to current or future participation in the Plan by electronic means. The Participant hereby consents to receive such documents
by electronic delivery and agrees to participate in the Plan through an on-line or electronic system established and maintained
by the Company or a third party designated by the Company.

 

25.             
Acceptance and Agreement by the Participant; Forfeiture upon Failure to Accept. By accepting the Restricted Stock
Units (including through electronic means), the Participant agrees to be bound by the terms, conditions, and restrictions set forth
in the Plan, this Agreement, and the Company’s policies, as in effect from time to time, relating to the Plan. The Participant’s
rights under the Restricted Stock Units will lapse 90 days from the Date of Grant, and the Restricted Stock Units will be forfeited
on such date if the Participant shall not have accepted this Agreement by such date. For the avoidance of doubt, the Participant’s
failure to accept this Agreement shall not affect the Participant’s continuing obligations under any other agreement between
the Company and the Participant. By accepting the Restricted Stock Units, Participant expressly agrees that Participant has reviewed
and agrees to abide by the Company’s Securities Trading Policy, as such may be revised or updated from time to time.

 

26.             
No Advice Regarding Grant. The Company is not providing any tax, legal, or financial advice, nor is the Company
making any recommendations regarding the Participant’s participation in the Plan, or the Participant’s acquisition
or sale of the underlying Shares. The Participant is hereby advised to consult with his or her own personal tax, legal, and financial
advisors regarding his or her participation in the Plan before taking any action related to the Plan.

 

27.             
Appendices for Non-U.S. Participants. Notwithstanding any provisions in this Agreement, Participants residing
and/or working outside the United States shall be subject to the Terms and Conditions for Non-U.S. Participants attached hereto
as Appendix B. If the Participant relocates from the United States to another country, the Terms and Conditions for Non-U.S.
Participants and the applicable country-specific terms and conditions will apply to the Participant, to the extent the Company
determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. Moreover,
if the Participant relocates between any of the countries included in country-specific terms and conditions, the special terms
and conditions for such country will apply to the Participant, to the extent the Company determines that the application of such
terms and conditions is necessary or advisable for legal or administrative reasons. The Terms and Conditions for Non-U.S. Participants
and the country-specific terms and conditions constitute part of this Agreement.

 

28.             
Imposition of Other Requirements. The Company reserves the right to impose other requirements on the Participant’s
participation in the Plan, on the Restricted Stock Units and on any Shares acquired under the Plan, to the extent the Company determines
it is necessary or advisable for legal or administrative reasons, and to require the Participant to sign any additional agreements
or undertakings that may be necessary to accomplish the foregoing.

the Company or who left the Employment of the Company coincident with, or within six (6) months prior to or after, the termination
of Participant’s Employment with the Company.

 

		(iii)	During the Restricted Period, Participant will not, whether on Participant’s own behalf or on behalf of or in conjunction
with any person, directly or indirectly solicit or assist in soliciting in competition with the Company, the business of any client
or prospective client:

 

		(A)	with whom Participant had personal contact or dealings on behalf of the Company during the one (1) year period preceding Participant’s
termination of Employment;

 

		(B)	with whom employees reporting to Participant have had personal contact or dealings on behalf of the Company during the one
(1) year immediately preceding Participant’s termination of Employment; or

 

		(C)	for whom Participant had direct or indirect responsibility during the one (1) year immediately preceding Participant’s
termination of Employment.

 

Notwithstanding anything to the contrary in this
Agreement, Participant may, directly or indirectly own, solely as an investment, securities of any person which are publicly traded
on a national or regional stock exchange or on the over-the-counter market if Participant (x) is not a controlling person
of, or a member of a group which controls, such person and (y) does not, directly or indirectly, own 5% or more of any class
of securities of such person.

 

		(c)	During the Restricted Period, Participant will not, directly or indirectly, solicit or encourage to cease to work with the
Company any consultant then under contract with the Company.

 

		(d)	Participant will not, other than as required by law or by order of a court or other competent authority, make or publish, or
cause any other person to make or publish, any statement that is disparaging or that reflects negatively upon the Company, or that
is or reasonably would be expected to be damaging to the reputation of the Company.

 

		(e)	It is expressly understood and agreed that although Participant and the Company consider the restrictions contained in this
Appendix A to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time
or territory or any other restriction contained in this Agreement is an unenforceable restriction against Participant, the provisions
of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to
such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, if any court of competent
jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so
as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained herein.

 

     

     

    

 

Appendix A - 4

 

		(f)	The period of time during which the provisions of this Appendix A shall be in effect shall be extended by the length
of time during which Participant is in breach of the terms hereof as determined by any court of competent jurisdiction on the Company’s
application for injunctive relief.

 

		2.	Specific Performance; Survival.

 

		(a)	Participant acknowledges and agrees that the Company’s remedies at law for a breach or threatened breach of any of the
provisions of this Appendix A would be inadequate and the Company would suffer irreparable damages as a result of such breach
or threatened breach. In recognition of this fact, Participant agrees that, in the event of such a breach or threatened breach,
in addition to any remedies at law, the Company, without posting any bond, shall be entitled to suspend making any payments or
providing any benefit otherwise required by this Agreement and obtain equitable relief in the form of specific performance, temporary
restraining order, temporary or permanent injunction, or any other equitable remedy which may then be available.

 

		(b)	The provisions of this Appendix A shall survive the termination of Participant’s Employment for any reason.

 

		3.	Protected Activities.

 

		(a)	Nothing in this Appendix A shall prohibit or impede Participant from communicating, cooperating or filing a complaint
on possible violations of U.S. federal, state or local law or regulation to or with any governmental agency or regulatory authority
(collectively, a “Governmental Entity”), including, but not limited to, the Securities and Exchange Commission,
the Financial Industry Regulatory Authority, Inc., the Equal Employment Opportunity Commission, or the National Labor Relations
Board, or from making other disclosures to any Governmental Entity that are protected under the whistleblower provisions of U.S.
federal, state, or local law or regulation; provided, that in each case, such communications and disclosures are consistent
with applicable law. Participant shall not be held criminally or civilly liable under any U.S. federal or state trade secret law
for the disclosure of a trade secret that is made (i) in confidence to a U.S. federal, state, or local government official or to
an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other
document filed in a lawsuit or other proceeding, if such filing is made under seal. An individual who files a lawsuit for retaliation
by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use
the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal,
and does not disclose the trade secret, except pursuant to court order. Moreover, Participant shall not be required to give prior
notice to (or get prior authorization from) the Company regarding any such communication or disclosure.

 

     

     

    

 

Appendix A - 5

 

		(b)	Except as otherwise provided in Section 3(a) of this Appendix A or under applicable law, under no circumstance is Participant
authorized to disclose any information covered by the Company’s or its affiliates’ attorney-client privilege or attorney
work product or the Company’s trade secrets without the prior written consent of the Company.

 

     

     

    

 

Appendix B - 1

 

APPENDIX B

 

SUMMIT MATERIALS, INC. 

2015 OMNIBUS INCENTIVE PLAN 

RESTRICTED STOCK UNIT AGREEMENT

 

TERMS AND CONDITIONS FOR NON-U.S. PARTICIPANTS

 

Capitalized terms used but not otherwise
defined herein shall have the meaning given to such terms in the Plan and the Restricted Stock Unit Agreement.

 

1.            Responsibility for Taxes. This provision supplements Section 8 of the Restricted Stock Unit Agreement:

 

(a)              
The Participant acknowledges that, regardless of any action taken by the Company or, if different, the Employer, the ultimate
liability for all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items
related to the Participant’s participation in the Plan and legally applicable to the Participant (“Tax-Related Items”)
is and remains the Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer.
The Participant further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding
the treatment of any Tax-Related Items in connection with any aspect of the Restricted Stock Units, including, but not limited
to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such settlement
and the receipt of any dividends and/or any other distributions; and (ii) do not commit to and are under no obligation to
structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or eliminate the Participant’s liability
for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more
than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, the
Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or
account for Tax-Related Items in more than one jurisdiction.

 

(b)           Prior to any relevant taxable or tax withholding event, as applicable, the Participant agrees to make adequate arrangements
satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, the Participant authorizes the
Company and/or the Employer, or their respective agents, at their discretion, to satisfy their withholding obligations with regard
to all Tax-Related Items by:

 

(i)              
withholding from the Participant’s wages or other cash compensation paid to the Participant by the Company and/or
the Employer; or

 

(ii)             
withholding from proceeds of the sale of Shares acquired at settlement of the Restricted Stock Units either through a voluntary
sale or through a mandatory sale arranged by the Company (on the Participant’s behalf pursuant to this authorization) without
further consent; or

 

     

     

    

 

Appendix B - 2

 

(iii)           
withholding in Shares to be issued upon settlement of the Restricted Stock Units;

 

provided, however, that if the Participant is
a Section 16 officer of the Company under the Exchange Act, then the Company will withhold in Shares upon the relevant taxable
or tax withholding event, as applicable, unless the use of such withholding method is problematic under applicable tax or securities
law or has materially adverse accounting consequences, in which case, the obligation for Tax-Related Items may be satisfied by
one or a combination of methods (i) and (ii) above.

(c)              
Depending on the withholding method, the Company may withhold or account for Tax-Related Items by considering applicable
minimum statutory withholding rates or other applicable withholding rates, including maximum applicable rates, in which case the
Participant will receive a refund of any over-withheld amount in cash and will have no entitlement to the Common Stock equivalent.
If the obligation for Tax-Related Items is satisfied by withholding in Shares, for tax purposes, the Participant is deemed to have
been issued the full number of Shares subject to the portion of the Restricted Stock Units that is settled, notwithstanding that
a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.

 

(d)              
Finally, the Participant agrees to pay to the Company or the Employer, any amount of Tax-Related Items that the Company
or the Employer may be required to withhold or account for as a result of the Participant’s participation in the Plan that
cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the Shares or the proceeds of
the sale of Shares if the Participant fails to comply with the Participant’s obligations in connection with the Tax-Related
Items.

 

2.            Nature of Grant. This provision supplements Section 21 of the Restricted Stock Unit Agreement:

 

In accepting the grant of the Restricted
Stock Units, the Participant acknowledges, understands and agrees that:

 

(a)              
the Restricted Stock Unit grant and the Participant’s participation in the Plan shall not create a right to employment
or be interpreted as forming an employment or services contract with the Company or any Affiliate;

 

(b)              
the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not intended to replace any pension
rights or compensation;

 

(c)              
for purposes of the Restricted Stock Units, the date of Termination shall be the date the Participant is no longer actively
providing services to the Company or its Affiliates (regardless of the reason for such termination and whether or not later to
be found invalid or in breach of employment laws in the jurisdiction where the Participant is employed or the terms of the Participant’s
employment agreement, if any), and unless otherwise expressly provided in this Agreement or determined by the Company, the Participant’s
right to vest in the Restricted Stock Units under the Plan, if any, will terminate and the Participant’s right to have settled
any vested Restricted Stock Units, if any, will be measured as of such date and will not be extended by any notice period (e.g.,
the Participant’s period of service would not include any contractual notice period or any period of “garden leave”
or similar period mandated under employment laws in the jurisdiction where the Participant is employed or the terms of the Participant’s
employment agreement, if any); the Committee shall have the exclusive discretion to determine when the Participant is no longer
actively providing services for purposes of the Restricted Stock Unit grant (including whether the Participant may still be considered
to be providing services while on a leave of absence);

 

     

     

    

 

Appendix B - 3

 

(d)              
unless otherwise provided in the Plan or by the Company in its discretion, the Restricted Stock Units and the benefits evidenced
by this Agreement do not create any entitlement to have the Restricted Stock Units or any such benefits transferred to, or assumed
by, another company nor to be exchanged, cashed out or substituted for, in connection with any corporate transaction affecting
the Company’s Common Stock; and

 

(e)              
neither the Company nor any Affiliate shall be liable for any foreign exchange rate fluctuation between the Participant’s
local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts due to the
Participant pursuant to the settlement of the Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement.

 

3.            Insider Trading Restrictions/Market Abuse Laws. The Participant acknowledges that, depending on his or her country
of residence, the Participant may be subject to insider trading restrictions and/or market abuse laws, which may affect his or
her ability to acquire or sell Shares or rights to Shares (e.g., Restricted Stock Units) under the Plan during such times
as the Participant is considered to have “inside information” regarding the Company (as defined by the laws in the
Participant’s country). Any restrictions under these laws or regulations are separate from and in addition to any restrictions
that may be imposed under any applicable Company insider trading policy. The Participant is responsible for ensuring compliance
with any applicable restrictions and is advised to consult his or her personal legal advisor on this matter.Document
