Exhibit 10.21

 

RESTRICTED STOCK UNIT
AGREEMENT 

 

Dear ______:

 

Waste Connections, Inc. (the “Company”) is pleased
to inform you that you have been awarded Restricted Stock Units (the “Award”) under the Company’s 2014 Incentive
Award Plan (the “Plan”). Each Restricted Stock Unit represents the right to receive one share of the Company’s
common stock (“Common Stock”) pursuant to the Plan, to the extent vested on the vesting date of that unit. The Award
will vest in a series of installments over your period of continued service with the Company as set forth herein. Unlike a typical
stock option program, the shares will be issued to you as a bonus for your continued service over the vesting period, without any
cash payment required from you. However, you must pay the applicable income and employment withholding taxes (described below)
when due.

 

The award under this Restricted Stock Unit Agreement (the “Agreement”)
is in connection with and in furtherance of the Company’s compensatory benefit plan for participation of the Company’s
Employees, Directors and Consultants. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed
to them in the Plan.

 

This Agreement sets the number of shares of the Common Stock
subject to your award, the applicable vesting schedule for the issuance of those shares, and the remaining terms and conditions
governing your award.

 

Award Date: _____________

 

Number of Shares Subject to Award: ______________ shares
of Common Stock (the “Shares”)

 

Vesting Schedule: The Award will vest and become issuable
in a series of four (4) successive equal annual installments upon your completion of each year of Continuous Status as an Employee,
Director or Consultant over the four (4)-year period measured from the Award Date. However, no Shares with respect to which the
Award has vested in accordance with such schedule will actually be issued until you satisfy all applicable income and employment
withholding taxes. The Shares subject to the Award that have become vested are referred to as “Vested Award Units.”

 

Other important features of your Award may be summarized as
follows:

 

1.            Forfeitability:
Should your Continuous Status as an Employee, Director or Consultant cease for any reason prior to vesting in one or more installments
of the Shares subject to your Award, then your Award will be cancelled with respect to the unvested Shares and the number of your
Restricted Stock Units will be reduced accordingly, and you will cease to have any right or entitlement to receive any Shares under
those cancelled units.

 

    	Page 1

    	 

    

 

2.            Distribution.

 

(a)          The
Restricted Stock Units shall be distributed in Shares (either in book-entry form or otherwise), as soon as administratively practicable
following the vesting of the applicable Restricted Stock Unit, and, in any event, within sixty (60) days following such vesting.
Notwithstanding the foregoing, the Company may delay a distribution or payment in settlement of Restricted Stock Units if it reasonably
determines that such payment or distribution will violate federal securities laws or any other Applicable Law, provided
that such distribution or payment shall be made at the earliest date at which the Company reasonably determines that the making
of such distribution or payment will not cause such violation, as required by Treasury Regulation Section 1.409A-2(b)(7)(ii), and
provided further that no payment or distribution shall be delayed under this Section 2(a) if such delay will result in a
violation of Section 409A of the Code.

 

(b)          All
distributions shall be made by the Company in the form of whole Shares, and any fractional share shall be applied to the payment
of withholding taxes.

 

3.            Transferability:
Prior to your actual receipt of the Shares pursuant to your Award, you may not transfer any interest in your Award or the underlying
Shares in any manner (including pledging or hedging the sale of the Shares, including without limitation, any short sale, put or
call option or any other instrument tied to the value of the Shares) other than by will or the laws of descent and distribution
and no Restricted Stock Units or any interest or right therein or part thereof shall be liable for the debts, contracts or engagements
of you or your successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance,
assignment or any other means whether such disposition be voluntary or involuntary or by operation of law by judgment, levy, attachment,
garnishment or any other legal or equitable proceedings (including bankruptcy). Any attempt by you to do so will result in an immediate
forfeiture of the Restricted Stock Units awarded to you hereunder. However, your right to receive any Shares which have vested
under your Restricted Stock Units but which remain unissued at the time of your death may be transferred pursuant to the provisions
of your will or the laws of inheritance or to your designated beneficiary following your death. In the event the Shares which vest
hereunder are to be issued to the executors, administrators, heirs or distributees of your estate or to your designated beneficiary,
the Company shall be under no obligation to effect such issuance unless and until the Committee is satisfied that the person to
receive those Shares is the duly appointed legal representative of your estate or the proper legatee or distributee thereof or
your named beneficiary.

 

Any Shares issued to you pursuant to the
terms of this Agreement may not be sold or transferred in contravention of (i) any market black-out periods the Company may impose
from time to time or (ii) the Company’s insider trading policies to the extent applicable to you.

 

4.            Adjustments:
The Administrator may accelerate the vesting of all or a portion of your Award in such circumstances as it, in its sole discretion,
may determine. You acknowledge that the Restricted Stock Units and the Shares subject to the Restricted Stock Units are subject
to adjustment, modification and termination in certain events as provided in this Agreement and the Plan, including Section 12
of the Plan.

 

5.            Federal
Income Taxation: You generally will recognize ordinary income for federal income tax purposes on the date the Shares subject
to your Award vest, and you must satisfy the income tax withholding obligation applicable to that income. The amount of your taxable
income will generally be based on the closing selling price per share of Common Stock on the New York Stock Exchange on the date
your Vested Award Units are issued and distributed times the number of Shares which are distributed on that date. This is a general
summary of the possible tax consequences of the Award and is not tax advice. You are advised to consult with your own advisor as
to the possible tax consequences of this Award.

 

    	Page 2

    	 

    

 

6.            FICA
Taxes: You will be liable for the payment of the employee share of the FICA (Social Security and Medicare) taxes applicable
to your Award, which liability will generally arise at the time your Award vests. FICA taxes will generally be based on the closing
selling price of the shares on the New York Stock Exchange on the date those Shares vest under your Award.

 

7.            Withholding
Taxes: You must pay all applicable federal, state and local income and employment withholding taxes when due.

 

(a)          In
the Company’s sole discretion, the Company may collect any applicable federal, state and local income and employment withholding
taxes with respect to the Award through an automatic Share withholding procedure pursuant to which the Company will withhold a
portion of those vested Shares with a fair market value (measured as of the date the withholding obligation arises) equal to the
amount of such withholding taxes (the “Share Withholding Method”); provided, however, that the amount of any Shares
so withheld shall not exceed the amount necessary to satisfy the Company’s required tax withholding obligations using the
minimum statutory withholding rates for federal, state and local tax purposes, including payroll taxes, that are applicable to
supplemental taxable income. You shall be notified in writing in the event such Share Withholding Method is no longer available.

 

(b)          Should
any Shares vest under the Award at a time when the Share Withholding Method is not available, then the Company may, in its sole
discretion, collect any applicable federal, state and local income and employment withholding taxes from you through any of the
following alternatives:

 

·          your
delivery of a separate check payable to the Company in the amount of such withholding taxes, or

·          the
use of the proceeds from a next-day sale of the Shares issued to you; provided and only if (i) such a sale is permissible under
the Company’s trading policies governing the sale of Common Stock, (ii) you make an irrevocable commitment, on or before
the vesting date for those Shares, to effect such sale of the Shares and (iii) the transaction is not otherwise deemed to constitute
a prohibited loan under Section 402 of the Sarbanes-Oxley Act of 2002.

 

8.            Stockholder
Rights: Neither you nor any person claiming under or through you will have any of the rights or privileges of a stockholder
of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may
be in book-entry form) will have been issued and recorded on the records of the Company or its transfer agents or registrars, and
delivered to you (including through electronic delivery to a brokerage account). Except as otherwise provided herein, after such
issuance, recordation and delivery, you will have all the rights of a stockholder of the Company with respect to such Shares, including,
without limitation, the right to receipt of dividends and distributions on such Shares.

 

    	Page 3

    	 

    

 

9.          Dividend
Equivalent Rights: Should the Board in its discretion declare an extraordinary cash dividend on the Common Stock at a time
when unissued shares of such Common Stock are subject to your Award, then the number of Shares at that time subject to your Award
will automatically be increased on the date the dividend is paid by an amount determined in accordance with the following formula,
rounded down to the nearest whole share:

 

X = (A x B)/C, where

 

X = the additional number of Shares which will become subject
to your Award by reason of the extraordinary cash dividend;

 

A = the number of unissued Shares subject to this Award as of
the record date for such dividend;

 

B = the per Share amount of the cash dividend; and

 

C = the closing selling price per share of Common Stock on the
New York Stock Exchange on the payment date of such dividend.

 

The additional Shares resulting from such calculation will be
subject to the same terms and conditions as the unissued Shares to which they relate under your Award. The Board has the discretion
to determine when a cash dividend shall be considered extraordinary. Your Award will not be adjusted to reflect regular or periodic
cash dividends. In order for you to receive a dividend equivalent increase to the number of Shares subject to your Award, you must
be in Continuous Status as an Employee, Director or Consultant on the date the extraordinary dividend is actually paid. These dividend
equivalent rights and any amounts that may become distributable in respect thereof shall be treated separately from the Restricted
Stock Units and the rights arising in connection therewith for purposes of the designation of time and form of payments required
by Section 409A of the Code.

 

10.         Change
in Control: In the event of a Change in Control, the vesting of the Shares subject to your Award will accelerate in full immediately
upon such Change in Control.

 

11.         Securities
Law Compliance: No Shares will be issued pursuant to your Award if such issuance would constitute a violation of any applicable
federal, state or foreign securities laws or other law or regulations or the requirements of any stock exchange or market system
on which the Common Stock may then be listed. In addition, no Shares will be issued unless:

 

(a)          a
registration statement under the Securities Act is in effect at that time with respect to the Shares to be issued; or

 

(b)          in
the opinion of legal counsel to the Company, those Shares may be issued in accordance with the terms of an applicable exemption
from the registration requirements of the Securities Act. The inability of the Company to obtain from any regulatory body having
jurisdiction the authority, if any, deemed by the Company’s legal counsel to be necessary to the lawful issuance of any Shares
hereunder shall relieve the Company of any liability in respect of the failure to issue such Shares as to which such requisite
authority shall not have been obtained. As a condition to the issuance of any Shares, the Company may require you to satisfy any
qualifications that may be necessary or appropriate to evidence compliance with any applicable law or regulation and to make any
representation or warranty with respect thereto as may be requested by the Company.

12.         Notice:
Any notice or other communication to be given under or in connection with this Agreement or the Plan shall be given in writing
and shall be deemed effectively given on receipt or, in the case of notices from the Company to you, five days after deposit in
the United States mail, postage prepaid, addressed to you at the address specified below or at such other address as you may hereafter
designate by notice to the Company.

 

13.         Remaining
Terms: The remaining terms and conditions of your Award are governed by the Plan, and your Award is also subject to all interpretations,
amendments, rules and regulations which may from time to time be adopted under the Plan. Along with this Agreement, you also received
a copy of the official prospectus summarizing the principal features of the Plan. Please review the plan prospectus carefully so
that you fully understand your rights and benefits under your Award and the limitations, restrictions and vesting provisions applicable
to the Award. In the event of any conflict between the provisions of this Agreement and those of the Plan, the provisions of the
Plan shall be controlling.

 

14.         Limitations:
Nothing in this Agreement or the Plan shall confer on you or any other person:

 

(a)          Any
rights or claims under the Plan except in accordance with the provisions of the Plan and the applicable Award agreement;

 

(b)          Any
right with respect to continuation of employment or a consulting or directorship arrangement with the Company or any Subsidiary,
nor shall they interfere in any way with the right of the Company or any Subsidiary that employs you or engages you as a consultant
or director to terminate your employment or consulting or directorship arrangement at any time, with or without cause;

 

(c)          Any
right to be selected to participate in the Plan or to be granted an Award; or

 

(d)          Any
right to receive any bonus, whether payable in cash or in Common Stock, or in any combination thereof, from the Company or its
Subsidiaries, nor be construed as limiting in any way the right of the Company or its Subsidiaries to determine, in its sole discretion,
whether or not it shall pay any employee, consultant or director bonuses, and, if so paid, the amount thereof and the manner of
such payment.

 

15.         Section
409A: This Award is not intended to constitute “nonqualified deferred compensation” within the meaning of Section
409A of the Code (together with any Department of Treasury regulations and other interpretive guidance issued thereunder, including
without limitation any such regulations or other guidance that may be issued after the date hereof, “Section 409A”).
However, notwithstanding any other provision of the Plan or this Agreement, if at any time the Administrator determines that this
Award (or any portion thereof) may be subject to Section 409A, the Administrator shall have the right in its sole discretion (without
any obligation to do so or to indemnify you or any other person for failure to do so) to adopt such amendments to the Plan or this
Agreement, or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take
any other actions, as the Administrator determines are necessary or appropriate for this Award either to be exempt from the application
of Section 409A or to comply with the requirements of Section 409A.

Grant Agreement for

Performance-Based Restricted Stock Units

 

	Holder:	[Name]
	 	 
	Address:	[Address]
	 	 
	Date of Grant:	[__________], 2014
	 	 
	Target Number:	[PBRSU Shares]
	 	 
	Performance Period:	[_______________________]
	 	 
	Plan Name:	Waste Connections, Inc. 2014 Incentive Award Plan
	 	 

 

Waste Connections, Inc., a Delaware corporation
(the “Company”) has adopted the 2014 Incentive Award Plan (the “Plan”) for the granting to
selected employees of awards based upon shares of Stock of the Company. In accordance with the terms of the Plan, the Compensation
Committee of the Board of Directors (the “Committee”) has approved the execution of this Performance-Based Restricted
Stock Unit Agreement (this “Agreement”) between the Company and the Holder, as specified in this Agreement.
Capitalized terms used herein without definition shall have the meanings assigned to such terms in the Plan.

 

1.          Grant.
The Company grants to the Holder the number of restricted stock units based on shares of Stock set forth in this Agreement (the
“Units”), subject to adjustment, forfeiture and the other terms and conditions set forth below, as of the effective
date of the grant (the “Grant Date”) specified in this Agreement. The number of Units specified in this Agreement
reflects the target number of Units that may be earned by the Holder. The Company and the Holder acknowledge that the Units will,
except as provided in Sections 4 and 5 hereof, be forfeited by the Holder if the Holder’s termination of employment occurs
before the Settlement Date (as defined in Section 2, below).

 

2.          Determination
of Earned Performance Units. The number of Units that may be earned by and issuable to the Holder (the “Earned
Units”) shall be based upon the achievement by the Company of the performance standards as reviewed and approved by the
Committee and reflected in the resolutions of the Committee (the “Performance Goals”) over the three-year period
indicated above (the “Performance Period”). The determination by the Committee with respect to the achievement
of the Performance Goals shall be made in its sole discretion and as soon as administratively practicable following the Performance
Period after all necessary Company information is available. The specific date on which such determination is formally made and
approved by the Committee is referred to as the “Determination Date.” Within 15 business days following the
Determination Date, but in no event later than March 15th of the fiscal year following the end of the Performance Period (the “Settlement
Date”), the Company shall notify the Holder of the number of Units, if any, that have become Earned Units and the corresponding
number of shares of Stock to be issued to the Holder in satisfaction of this award of Units, and settle each Earned Unit by delivering
to the Holder one share of Stock, subject to withholding as described in Section 9 below. The number of Units which may become
Earned Units will be between 0% and [____]% of the Target Number of Units depending on whether and to what extent the Performance
Goals are achieved by the Company. The Company shall (a) issue or cause to be delivered to the Holder (or the Holder’s Heir,
as defined below, if applicable) one or more unlegended stock certificates representing such shares, or (b) cause a book entry
for such shares to be made in the name of the Holder (or the Holder’s Heir, if applicable). In the case of the Holder’s
death, Stock to be delivered in settlement of Units as described above shall be delivered to the Holder’s beneficiary or
beneficiaries (as designated in the manner determined by the Committee), or if no beneficiary is so designated or if no beneficiary
survives the Holder, then the Holder’s administrator, executor, personal representative, or other person to whom the Units
are transferred by means of the Holder’s will or the laws of descent and distribution (such beneficiary, beneficiaries or
other person(s), the “Holder’s Heir”).

 

    	 

    	 

    

  

3.          Dividend
Equivalent Rights. The Holder shall have no rights to dividends or other rights of a stockholder with respect to the Units
unless and until such time as the award of Units has been settled by the issuance of Stock to the Holder. The Holder shall have
the right to receive a cash dividend equivalent payment with respect to the Earned Units for cash dividends payable to holders
of Stock as of a record date designated by the Company that is within the period beginning on the Grant Date and ending on the
Settlement Date, which dividend equivalent payment shall be payable to the Holder on the Settlement Date, without interest. In
the event of forfeiture of the Units, the Holder shall have no further rights with respect to such Units.

 

4.          Consequences
of Termination of Employment. The consequences of the Holder’s termination of employment with the Company (a “Termination
of Employment”) during the Performance Period shall be as follows:

 

i.          In
the case of a Termination of Employment by the Company for Cause, the Units shall be forfeited as of the date of the Termination
of Employment.

 

ii.         In
the case of a Termination of Employment by the Company without Cause (or by the Holder for Good Reason, but only to the extent
an Individual Agreement (as defined below) provides for the right to terminate employment for Good Reason and further provides
for severance payments and benefits due to such Termination of Employment) or Termination of Employment due to Disability or the
Holder’s death, the number of Units earned shall be determined as follows: first, the Committee shall determine the number
of Units earned based on actual achievement of the Performance Goals following the end of the Performance Period; and second, the
number of Units so obtained shall be multiplied by a fraction, the numerator of which is the total number of full months elapsed
from the first day of the Performance Period to the date of the Holder’s Termination of Employment and the denominator of
which is the total number of whole months in the Performance Period. Such number of Units shall then be settled in accordance with
Section 2 as for all other holders whose awards are settled on the Settlement Date.

 

    	-2-

    	 

    

  

iii.         In
all other cases, the Units shall be forfeited as of the date of the Termination of Employment.

 

For purposes of this Agreement, the
Holder’s Termination of Employment shall be considered to be for “Cause” if it is a termination for “Cause”
pursuant to an employment or separation agreement between the Company and the Holder or a Company severance or separation plan
applicable to the Holder (the “Individual Agreement”) to which the Holder is a party that is then in effect
or, if there is no Individual Agreement in effect that defines “Cause,” “Cause” shall mean (a) a
material breach by the Holder of any of the terms of the Individual Agreement, or any other agreement between the Company and the
Holder, that is not immediately corrected following written notice of default specifying such breach; (b) conviction of a felony;
(c) a breach of any non-competition or non-solicitation covenants in any agreement between the Company and the Holder; (d) repeated
intoxication with alcohol or drugs while on Company premises during its regular business hours to such a degree that, in the reasonable
judgment of the Chief Executive Officer or General Counsel of the Company, the Holder is abusive or incapable of performing his
or her duties and responsibilities; or (e) misappropriation of property belonging to the Company and/or any of its affiliates.

 

5.          Change
in Control. If a Change in Control occurs and the Holder has remained continuously employed by the Company until at least
immediately prior to the Change in Control, the number of Units earned shall be determined as follows:

 

i.          If
the Committee reasonably determines in good faith, prior to the occurrence of the Change in Control, that the Units will not be
honored or assumed, or new rights that substantially preserve the terms of the Units substituted therefor, by the Holder’s
employer (or the parent of such employer) immediately following the Change in Control, the number of Earned Units shall equal the
greater of (a) the number that equals 100% of the target award level payout and (b) the number that would have been earned based
on actual achievement of the Company Performance Goals through the most recently completed fiscal year prior to such Change in
Control (calculated as if the most recently completed fiscal year prior to such Change in Control had been the end of the applicable
Performance Period).

 

ii.         If
the Committee determines that the Units have been assumed and, before the Determination Date, the Holder has a Termination of Employment
by the Company without Cause or by the Holder for Good Reason within the 24-month period immediately following a Change in Control,
in lieu of the earnout and settlement of the Units pursuant to Section 4 above, the number of Units earned shall equal the greater
of (a) the number that equals 100% of the target award level payout and (b) the number that would have been earned based on actual
achievement of the Performance Goals through the most recently completed fiscal year prior to such Termination of Employment (calculated
as if the most recently completed fiscal year prior to such Termination of Employment had been the end of the applicable Performance
Period).

 

    	-3-

    	 

    

  

For purposes of this Agreement, the
Holder’s Termination of Employment shall be considered to be with “Good Reason” if it is a termination for “Good
Reason” pursuant to an Individual Agreement to which the Holder is a party that is then in effect or, if there is no Individual
Agreement in effect that defines “Good Reason,” “Good Reason” shall mean: (a) assignment to the
Holder of duties inconsistent with and resulting in a diminution of his or her position (including status, offices, titles, responsibilities
and reporting requirements), authority, duties or responsibilities as they existed on the Grant Date, or any other action by the
Company which results in a diminution in such position, authority, duties or responsibilities; a substantial alteration in the
title(s) of the Holder (so long as the existing corporate structure of the Company is maintained); provided, however, that the
Holder’s failure to serve in the same position (including status, offices, titles, responsibilities and reporting requirements)
with the ultimate parent of the Company shall constitute “Good Reason;” (b) the relocation of the Holder’s principal
place of employment to a location more than fifty (50) miles from its present location without the Holder’s prior approval;
(c) a material reduction by the Company in the Holder’s total annual cash compensation, defined as base salary and target
bonus, without the Holder’s prior approval; (d) a material reduction by the Company in the Holder’s total annual compensation,
defined as base salary, target bonus and equity incentive compensation opportunities, without the Holder’s prior approval;
(e) a failure by the Company to continue in effect, without substantial change, any benefit plan or arrangement in which the Holder
was participating or the taking of any action by the Company which would adversely affect the Holder’s participation in or
materially reduce his or her benefits under any benefit plan (unless such changes apply equally to all other similarly situated
employees of Company); (f) any material breach by the Company of any provision of the Individual Agreement or any other agreement
between the Company and the Holder, without the Holder having committed any material breach of his or her obligations hereunder,
which breach is not cured within twenty (20) days following written notice thereof to the Company of such breach; or (g) the failure
of the Company to obtain the assumption of this Agreement by any successor entity.

 

Any Units which are earned pursuant to this
Section 5 shall be settled on or within 60 days after the Change in Control or Termination of Employment, as applicable, but in
no event later than the Settlement Date, in accordance with Section 2.

 

6.          Claw-Back.
Pursuant to its general authority to determine the terms and conditions applicable to the Units, the Committee shall have the right
to require the Holder to agree by separate written or electronic instrument that the Units (including any proceeds, gains or other
economic benefit actually or constructively received by the Holder upon any receipt of the Units or upon the receipt or resale
of any Shares underlying the Units) shall be subject to the provisions of any claw-back policy implemented by the Company, including,
without limitation, any claw-back policy adopted to comply with the requirements of Applicable Law, including without limitation
the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder, to the extent
set forth in such claw-back policy.

7.          Vesting;
Service Requirement. Except as provided in Sections 4 and 5, subject to the Holder’s continuous employment through
the Determination Date, the number of Earned Units determined pursuant to Section 2 shall vest on the Determination Date.

 

8.          Code
Section 409A. The Company intends that the Units shall not constitute “deferred compensation” within the meaning
of Section 409A of the Code and this Agreement shall be interpreted based on such intent. In view of uncertainty surrounding Section
409A of the Code, however, if the Company determines after the Grant Date that an amendment to this Agreement is necessary or advisable
so that the Units will not be subject to Section 409A of the Code, or alternatively so that they comply with Section 409A of the
Code, it may make such amendment, effective as of the Grant Date or at any later date, without the consent of the Holder.

 

Notwithstanding anything in this Agreement
to the contrary, to the extent that any payment or benefit constitutes non-exempt “nonqualified deferred compensation”
for purposes of Section 409A of the Code, and such payment or benefit would otherwise be payable or distributable hereunder by
reason of the Holder’s Termination of Employment, all references to the Holder’s Termination of Employment shall be
construed to mean a “separation from service,” as defined in Treasury Regulation Section 1.409A-1(h) (a “Separation
from Service”), and the Holder shall not be considered to have a Termination of Employment unless such termination constitutes
a Separation from Service with respect to the Holder.

 

9.          Tax
Withholding. The Company shall withhold from the Stock delivered in settlement of Units shares of Stock having a Fair Market
Value on the Settlement Date, equal to the amount necessary to satisfy the minimum required withholding, if any, of any income
tax, social tax, or other taxes (but rounding up to the nearest whole number of shares). In lieu of withholding shares of Stock,
the Committee may, in its discretion, authorize the satisfaction of tax withholding by a cash payment to the Company, by withholding
an appropriate amount of cash from base pay, or by such other method as the Committee determines may be appropriate to satisfy
all obligations for withholding of such taxes. If any such taxes are required to be withheld at a date earlier than the Settlement
Date, then notwithstanding any other provision of this Agreement, the Company may (i) satisfy such obligation by causing the forfeiture
of a number of Units having a Fair Market Value, on such earlier date, equal to the amount necessary to satisfy the minimum required
amount of such withholding, or (ii) make such other arrangements with the Holder for such withholding as may be satisfactory to
the Company in its sole discretion. The obligations of the Company under this award of Units will be conditioned on such satisfaction
of the required withholding. The Holder acknowledges that the tax consequences associated with this award of Units are complex
and that the Company has urged the Holder to review with the Holder’s own tax advisors the federal, state and local tax consequences
of this award of Units. The Holder is relying solely on such advisors and not on any statements or representations of the Company
or any of its agents. The Holder understands that he or she (and not the Company) shall be responsible for the Holder’s own
tax liability that may arise as a result of the award of Units.

10.         Compliance
with Law.

 

i.           No
shares of Stock shall be issued and delivered pursuant to a Unit unless and until all applicable registration requirements of the
Securities Act of 1933, as amended, all applicable listing requirements of any national securities exchange on which the Stock
is then listed, and all other requirements of law or of any regulatory bodies having jurisdiction over such issuance and delivery,
shall have been complied with. In particular, the Committee may require certain investment (or other) representations and undertakings
in connection with the issuance of securities in connection with the Plan in order to comply with Applicable Law.

 

ii.         If
any provision of this Agreement is determined to be unenforceable or invalid under any Applicable Law, such provision will be applied
to the maximum extent permitted by Applicable Law, and shall automatically be deemed amended in a manner consistent with its objectives
to the extent necessary to conform to any limitations required under Applicable Law. Furthermore, if any provision of this Agreement
is determined to be illegal under any Applicable Law, such provision shall be null and void to the extent necessary to comply with
Applicable Law, but the other provisions of this Agreement shall remain in full force and effect.

 

11.         Assignability.
Except as may be effected by designation of a beneficiary or beneficiaries in such manner as may be determined by the Committee,
or as may be effected by will or other testamentary disposition or by the laws of descent and distribution, any attempt to assign
the Units before they are settled shall be of no effect.

 

12.         Certain
Corporate Transactions. In the event of certain corporate transactions, the Units shall be subject to adjustment as provided
in Section 12 of the Plan.

 

13.         No
Additional Rights.

 

i.           Neither
the granting of the Units nor their settlement shall (a) affect or restrict in any way the power of the Company to undertake any
corporate action otherwise permitted under Applicable Law, (b) confer upon the Holder the right to continue performing services
for the Company, or (c) interfere in any way with the right of the Company to terminate the services of the Holder at any time,
with or without Cause. The Holder expressly acknowledges and agrees that he or she is an employee at will.

 

ii.         The
Holder acknowledges that (a) this is a one-time grant, (b) the making of this grant does not mean that the Holder will receive
any similar grant or grants in the future, or any future grants at all, and (c) this grant does not in any way entitle the Holder
to future grants under the Plan, if any, and the Committee retains sole and absolute discretion as to whether to make any additional
grants to the Holder in the future and, if so, the quantity, terms, conditions and provisions of any such grants.

iii.        Without
limiting the generality of subsections i. and ii. immediately above and subject to Sections 4 and 5 above, if the Holder’s
employment with the Company terminates, the Holder shall not be entitled to any compensation for any loss of any right or benefit
or prospective right or benefit relating to the Units or under the Plan which he or she might otherwise have enjoyed, whether such
compensation is claimed by way of damages for wrongful dismissal or other breach of contract or by way of compensation for loss
of office or otherwise.

 

14.         Rights
as a Stockholder. Neither the Holder nor the Holder’s Heir shall have any rights as a stockholder with respect to
any shares represented by the Units unless and until shares of Stock have been issued in settlement thereof.

 

15.         Data
Privacy Waiver. By accepting the grant of the Units, the Holder hereby agrees and consents to:

 

i.           the
collection, use, processing and transfer by the Company and its Subsidiaries (collectively, the “Group”) of
certain personal information about the Holder (the “Data”);

 

ii.         any
members of the Group transferring Data amongst themselves for the purposes of implementing, administering and managing the Plan;

 

iii.        the
use of such Data by any such person for such purposes; and

 

iv.        the
transfer to and retention of such Data by third parties in connection with such purposes.

 

For the purposes of clause (i) above, “Data”
means the Holder’s name, home address and telephone number, date of birth, other employee information, any tax or other identification
number, details of all rights to acquire Stock granted to the Holder and of Stock issued or transferred to the Holder pursuant
to the Plan.

 

16.         Compliance
with Plan. The Units and this Agreement are subject to, and the Company and the Holder agree to be bound by, all of the
terms and conditions of the Plan as it shall be amended from time to time, which are incorporated herein by reference. The Company
hereby reserves the right to amend, modify, restate, supplement or terminate the Plan without the consent of the Holder, so long
as such amendment, modification, restatement or supplement shall not materially reduce the rights and benefits available to the
Holder hereunder, and this award of Units shall be subject, without further action by the Company or the Holder, to such amendment,
modification, restatement or supplement unless provided otherwise therein. In the case of a conflict between the terms of the Plan
and this Agreement, the terms of the Plan shall govern.

 

17.         Effect
of Agreement on Individual Agreements. Notwithstanding the provisions of any Individual Agreement, (i) in the case of a
conflict between the terms of the Holder’s Individual Agreement and this Agreement, the terms of this Agreement shall govern,
and (ii) the vesting and settlement of Units shall in all events occur in accordance with this Agreement to the exclusion of any
provisions contained in an Individual Agreement regarding the vesting or settlement of the Units, and any such Individual Agreement
provisions shall have no force or effect with respect to the Units.

18.         Governing
Law and Jurisdictional Agreement. The interpretation, performance and enforcement of this Agreement shall be governed by
the laws of the State of Delaware without regard to principles of conflicts of laws. The Holder may only exercise his or her rights
in respect of the Plan to the extent that it would be lawful to do so, and the Company would not, in connection with this Agreement,
be in breach of the laws of any jurisdiction to which the Holder may be subject. The Holder shall be solely responsible to seek
advice as to the laws of any jurisdiction to which he or she may be subject, and participation by the Holder in the Plan shall
be on the basis of a warranty by the Holder that the Holder may lawfully so participate without the Company being in breach of
the laws of any such jurisdiction. The Company and Holder irrevocably and unconditionally submit to the jurisdiction and venue
of any state court situated within Montgomery County, Texas, and any federal court closest to or serving Montgomery County, Texas,
for the purpose of any suit, action or other proceeding arising out of, or relating to or in connection with, this Agreement. THE
PARTIES ALSO EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A JURY TRIAL OF ANY SUCH SUIT, ACTION OR PROCEEDING. If any one
or more provisions of this Section 18 shall for any reason be held invalid or unenforceable, it is the specific intent of the parties
to this Agreement that such provisions shall be modified to the minimum extent necessary to make it or its application valid and
enforceable.
