THIS RESTRICTED STOCK AWARD AGREEMENT (this “Agreement”), dated as of the Grant Date specified above, is entered into by and between U.S. Silica Holdings, Inc., a corporation organized in the State of Delaware (the “Company”), and the Participant specified above, pursuant to the Amended and Restated U.S. Silica Holdings, Inc. 2011 Incentive Compensation Plan, as in effect and as amended from time to time (the “Plan”), which is administered by the Committee; and
WHEREAS, it has been determined under the Plan that it would be in the best interests of the Company to grant the shares of Restricted Stock provided herein to the Participant.
NOW, THEREFORE, in consideration of the mutual covenants and promises hereinafter set forth, including the Restrictive Covenants in Section 12, and for other good and valuable consideration, the parties hereto hereby mutually covenant and agree as follows:

1.Incorporation By Reference; Plan Document Receipt.  This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments thereto adopted at any time and from time to time unless such amendments are expressly intended not to apply to the Award provided hereunder), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were each expressly set forth herein.  Any capitalized term not defined in this Agreement shall have the same meaning as is ascribed thereto in the Plan.  The Participant hereby acknowledges receipt of a true copy of the Plan and that the Participant has read the Plan carefully and fully understands its content.  In the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control.
2.    Grant of Restricted Stock Award.  The Company hereby grants to the Participant, as of the Grant Date specified above, the number of shares of Restricted Stock specified above.  Except as otherwise provided by the Plan, the Participant agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection 

	
			
	 
	 
	 

against potential future dilution of the Participant’s interest in the Company for any reason, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such shares, except as otherwise specifically provided for in the Plan or this Agreement.  Subject to Section 5 hereof, the Participant shall not have the rights of a stockholder in respect of the shares underlying this Award until such shares are delivered to the Participant in accordance with Section 4 hereof.
3.    Vesting.
(i)       The Restricted Stock subject to this grant shall become unrestricted and vested as follows, provided that the Participant has not incurred a Termination prior to each such vesting date:
[[ALLVESTSEGS]]

There shall be no proportionate or partial vesting in the periods prior to each vesting date and all vesting shall occur only on the appropriate vesting date, subject to the Participant’s continued service with the Company or any of its Subsidiaries on each applicable vesting date.

(ii)       Termination due to death or Disability, without Cause or due to Retirement.  Subject to the provisions of Sections 3(c) and 3(d) hereof, in the event of the Participant’s Termination as a result of death or Disability, by the Company without Cause or due to the Participant’s “Retirement” (as defined below), the unvested shares of Restricted Stock that would have become vested at the vesting date immediately following such Termination as provided in Section 3(a) hereof shall become vested on a pro rata basis (determined by multiplying the number of such unvested shares of Restricted Stock by a fraction, the numerator of which is the number of calendar days in the period beginning with, if prior to the first vesting date as set forth in Section 3(a) hereof, the Grant Date or, if after the first vesting date as set forth in Section 3(a) hereof, the vesting date immediately preceding the date of such Termination as set forth in Section 3(a) hereof and ending on the date of such Termination, and the denominator of which is three hundred sixty five (365)), and unrestricted shares shall be delivered in respect thereof as provided in Section 4 hereof.  
For purposes hereof, the term “Retirement” shall mean the Participant’s voluntary Termination of Employment at or after age sixty-five (65) or such earlier date after age fifty (50), in either case, as may be approved by the Committee in its sole discretion with regard to the Participant.
(iii)       Change in Control.  Notwithstanding the provisions of Sections 3(a) and 3(b) hereof, in the event of the Participant’s Termination as a result of death or Disability, by the Company without Cause or as a result of the Participant’s Retirement, in any case, at any time upon or following a Change in Control, the unvested shares of Restricted Stock shall become fully vested, and unrestricted shares shall be delivered in respect thereof, as provided in Section 4 hereof.

(iv)       Committee Discretion to Accelerate Vesting.  Notwithstanding the foregoing, the Committee may, in its sole discretion, provide for accelerated vesting of the shares of Restricted Stock at any time and for any reason.
(v)       Effect of Detrimental Activity.  The provisions of Section 10.4 of the Plan regarding Detrimental Activity shall apply to the Restricted Stock.
(vi)       Forfeiture.  Subject to the provisions of Sections 3(b) through 3(d) hereof, all unvested shares of Restricted Stock shall be immediately forfeited upon the Participant’s Termination for any reason.
4.    Period of Restriction; Delivery of Unrestricted Shares.   During the Period of Restriction, the Restricted Stock shall bear a legend as described in Section 8.2(c) of the Plan.  When shares of Restricted Stock awarded by this Agreement become vested, the Participant shall be entitled to receive unrestricted shares and if the Participant’s stock certificates contain legends restricting the transfer of such shares, the Participant shall be entitled to receive new stock certificates free of such legends (except any legends requiring compliance with securities laws).
5.    Dividends and Other Distributions; Voting.  Participants holding Restricted Stock shall be entitled to receive all dividends and other distributions paid with respect to such shares, provided that any such dividends or other distributions will be subject to the same vesting requirements as the underlying Restricted Stock and shall be paid in cash and without interest at the time the Restricted Stock becomes vested pursuant to Section 3 hereof.  If any dividends or distributions are paid in shares, the shares shall be deposited with the Company and shall be subject to the same restrictions on transferability and forfeitability as the Restricted Stock with respect to which they were paid.  The Participant may exercise full voting rights with respect to the Restricted Stock granted hereunder.
6.    Non-Transferability.  The shares of Restricted Stock, and any rights and interests with respect thereto, issued under this Agreement and the Plan shall not, prior to vesting, be sold, exchanged, transferred, assigned or otherwise disposed of in any way by the Participant (or any beneficiary of the Participant), other than by testamentary disposition by the Participant or the laws of descent and distribution.  Any attempt to sell, exchange, transfer, assign, pledge, encumber or otherwise dispose of or hypothecate in any way any of the Restricted Stock, or the levy of any execution, attachment or similar legal process upon the Restricted Stock, contrary to the terms and provisions of this Agreement and/or the Plan shall be null and void and without legal force or effect.
7.    Governing Law.  All questions concerning the construction, validity and interpretation of this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the choice of law principles thereof.
8.    Withholding of Tax.  The Company shall have the power and the right to deduct or withhold, or require the Participant to remit to the Company, an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Participant’s FICA and SDI obligations) which the Company, in its sole discretion, deems necessary 

	
			
	 
	3
	 

to be withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the Restricted Stock and, if the Participant fails to do so, the Company may otherwise refuse to issue or transfer any shares of Common Stock otherwise required to be issued pursuant to this Agreement.  Any statutorily required withholding obligation with regard to the Participant may be satisfied by reducing the amount of cash or shares of Common Stock otherwise deliverable to the Participant hereunder.
9.    Section 83(b).  The Participant’s execution of this agreement will constitute the Participant’s waiver to make an election under Section 83(b) of the Code with respect to the Participant’s Award.  This waiver means that the Participant will not have the option of electing to be taxed on the Restricted Stock on the Grant Date.  Instead, the Participant will be taxed on the Restricted Stock as it becomes vested on each vesting date.  
10.    Legend.  All certificates representing the Restricted Stock shall have endorsed thereon the legend set forth in Section 8.2(c) of the Plan.  Notwithstanding the foregoing, in no event shall the Company be obligated to deliver to the Participant a certificate representing the Restricted Stock prior to the vesting dates set forth above.

The shares of Restricted Stock are being issued to the Participant and this Agreement is being made by the Company in reliance upon the following express representations and warranties of the Participant.  The Participant acknowledges, represents and warrants that:

(a)    If the Participant is deemed an affiliate within the meaning of Rule 144 of the Securities Act, the Participant understands that (i) the exemption from registration under Rule 144 will not be available unless (A) a public trading market then exists for the Common Stock of the Company, (B) adequate information concerning the Company is then available to the public, and (C) other terms and conditions of Rule 144 or any exemption therefrom are complied with, and (ii) any sale of the shares of vested Restricted Stock hereunder may be made only in limited amounts in accordance with the terms and conditions of Rule 144 or any exemption therefrom. 
12.    Restrictive Covenants.

*  *  *  *  *
THIS RESTRICTED STOCK AWARD AGREEMENT (this “Agreement”), dated as of the Grant Date specified above, is entered into by and between U.S. Silica Holdings, Inc., a corporation organized in the State of Delaware (the “Company”), and the Participant specified above, pursuant to the Amended and Restated U.S. Silica Holdings, Inc. 2011 Incentive Compensation Plan, as in effect and as amended from time to time (the “Plan”), which is administered by the Committee; and
WHEREAS, it has been determined under the Plan that it would be in the best interests of the Company to grant the shares of Restricted Stock provided herein to the Participant.
NOW, THEREFORE, in consideration of the mutual covenants and promises hereinafter set forth, including the Restrictive Covenants in Section 12, and for other good and valuable consideration, the parties hereto hereby mutually covenant and agree as follows:

1.Incorporation By Reference; Plan Document Receipt.  This Agreement is subject in all respects to the terms and provisions of the Plan (including, without limitation, any amendments thereto adopted at any time and from time to time unless such amendments are expressly intended not to apply to the Award provided hereunder), all of which terms and provisions are made a part of and incorporated in this Agreement as if they were each expressly set forth herein.  Any capitalized term not defined in this Agreement shall have the same meaning as is ascribed thereto in the Plan.  The Participant hereby acknowledges receipt of a true copy of the Plan and that the Participant has read the Plan carefully and fully understands its content.  In the event of any conflict between the terms of this Agreement and the terms of the Plan, the terms of the Plan shall control.
2.    Grant of Restricted Stock Award.  The Company hereby grants to the Participant, as of the Grant Date specified above, the number of shares of Restricted Stock specified above.  Except as otherwise provided by the Plan, the Participant agrees and understands that nothing contained in this Agreement provides, or is intended to provide, the Participant with any protection 

	
			
	 
	 
	 

against potential future dilution of the Participant’s interest in the Company for any reason, and no adjustments shall be made for dividends in cash or other property, distributions or other rights in respect of any such shares, except as otherwise specifically provided for in the Plan or this Agreement.  Subject to Section 5 hereof, the Participant shall not have the rights of a stockholder in respect of the shares underlying this Award until such shares are delivered to the Participant in accordance with Section 4 hereof.
3.    Vesting.
(i)       The Restricted Stock subject to this grant shall become unrestricted and vested as follows, provided that the Participant has not incurred a Termination prior to each such vesting date:
[[ALLVESTSEGS]]

There shall be no proportionate or partial vesting in the periods prior to each vesting date and all vesting shall occur only on the appropriate vesting date, subject to the Participant’s continued service with the Company or any of its Subsidiaries on each applicable vesting date.

(ii)       Termination due to death or Disability, without Cause or due to Retirement.  Subject to the provisions of Sections 3(c) and 3(d) hereof, in the event of the Participant’s Termination as a result of death or Disability, by the Company without Cause or due to the Participant’s “Retirement” (as defined below), the unvested shares of Restricted Stock that would have become vested at the vesting date immediately following such Termination as provided in Section 3(a) hereof shall become vested on a pro rata basis (determined by multiplying the number of such unvested shares of Restricted Stock by a fraction, the numerator of which is the number of calendar days in the period beginning with, if prior to the first vesting date as set forth in Section 3(a) hereof, the Grant Date or, if after the first vesting date as set forth in Section 3(a) hereof, the vesting date immediately preceding the date of such Termination as set forth in Section 3(a) hereof and ending on the date of such Termination, and the denominator of which is three hundred sixty five (365)), and unrestricted shares shall be delivered in respect thereof as provided in Section 4 hereof.  
For purposes hereof, the term “Retirement” shall mean the Participant’s voluntary Termination of Employment at or after age sixty-five (65) or such earlier date after age fifty (50), in either case, as may be approved by the Committee in its sole discretion with regard to the Participant.
(iii)       Change in Control.  Notwithstanding the provisions of Sections 3(a) and 3(b) hereof, in the event of the Participant’s Termination as a result of death or Disability, by the Company without Cause or as a result of the Participant’s Retirement, in any case, at any time upon or following a Change in Control, the unvested shares of Restricted Stock shall become fully vested, and unrestricted shares shall be delivered in respect thereof, as provided in Section 4 hereof.

	
			
	 
	2
	 

(iv)       Committee Discretion to Accelerate Vesting.  Notwithstanding the foregoing, the Committee may, in its sole discretion, provide for accelerated vesting of the shares of Restricted Stock at any time and for any reason.
(v)       Effect of Detrimental Activity.  The provisions of Section 10.4 of the Plan regarding Detrimental Activity shall apply to the Restricted Stock.
(vi)       Forfeiture.  Subject to the provisions of Sections 3(b) through 3(d) hereof, all unvested shares of Restricted Stock shall be immediately forfeited upon the Participant’s Termination for any reason.
4.    Period of Restriction; Delivery of Unrestricted Shares.   During the Period of Restriction, the Restricted Stock shall bear a legend as described in Section 8.2(c) of the Plan.  When shares of Restricted Stock awarded by this Agreement become vested, the Participant shall be entitled to receive unrestricted shares and if the Participant’s stock certificates contain legends restricting the transfer of such shares, the Participant shall be entitled to receive new stock certificates free of such legends (except any legends requiring compliance with securities laws).
5.    Dividends and Other Distributions; Voting.  Participants holding Restricted Stock shall be entitled to receive all dividends and other distributions paid with respect to such shares, provided that any such dividends or other distributions will be subject to the same vesting requirements as the underlying Restricted Stock and shall be paid in cash and without interest at the time the Restricted Stock becomes vested pursuant to Section 3 hereof.  If any dividends or distributions are paid in shares, the shares shall be deposited with the Company and shall be subject to the same restrictions on transferability and forfeitability as the Restricted Stock with respect to which they were paid.  The Participant may exercise full voting rights with respect to the Restricted Stock granted hereunder.
6.    Non-Transferability.  The shares of Restricted Stock, and any rights and interests with respect thereto, issued under this Agreement and the Plan shall not, prior to vesting, be sold, exchanged, transferred, assigned or otherwise disposed of in any way by the Participant (or any beneficiary of the Participant), other than by testamentary disposition by the Participant or the laws of descent and distribution.  Any attempt to sell, exchange, transfer, assign, pledge, encumber or otherwise dispose of or hypothecate in any way any of the Restricted Stock, or the levy of any execution, attachment or similar legal process upon the Restricted Stock, contrary to the terms and provisions of this Agreement and/or the Plan shall be null and void and without legal force or effect.
7.    Governing Law.  All questions concerning the construction, validity and interpretation of this Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the choice of law principles thereof.
8.    Withholding of Tax.  The Company shall have the power and the right to deduct or withhold, or require the Participant to remit to the Company, an amount sufficient to satisfy any federal, state, local and foreign taxes of any kind (including, but not limited to, the Participant’s FICA and SDI obligations) which the Company, in its sole discretion, deems necessary 

	
			
	 
	3
	 

to be withheld or remitted to comply with the Code and/or any other applicable law, rule or regulation with respect to the Restricted Stock and, if the Participant fails to do so, the Company may otherwise refuse to issue or transfer any shares of Common Stock otherwise required to be issued pursuant to this Agreement.  Any statutorily required withholding obligation with regard to the Participant may be satisfied by reducing the amount of cash or shares of Common Stock otherwise deliverable to the Participant hereunder.
9.    Section 83(b).  The Participant’s execution of this agreement will constitute the Participant’s waiver to make an election under Section 83(b) of the Code with respect to the Participant’s Award.  This waiver means that the Participant will not have the option of electing to be taxed on the Restricted Stock on the Grant Date.  Instead, the Participant will be taxed on the Restricted Stock as it becomes vested on each vesting date.  
10.    Legend.  All certificates representing the Restricted Stock shall have endorsed thereon the legend set forth in Section 8.2(c) of the Plan.  Notwithstanding the foregoing, in no event shall the Company be obligated to deliver to the Participant a certificate representing the Restricted Stock prior to the vesting dates set forth above.

11.    Securities Representations.  The shares of Restricted Stock are being issued to the Participant and this Agreement is being made by the Company in reliance upon the following express representations and warranties of the Participant.  The Participant acknowledges, represents and warrants that:
(a)    The Participant has been advised that the Participant may be an “affiliate” within the meaning of Rule 144 under the Securities Act and in this connection the Company is relying in part on the Participant’s representations set forth in this Section 11.

(c)    If the Participant is deemed an affiliate within the meaning of Rule 144 of the Securities Act, the Participant understands that (i) the exemption from registration under Rule 144 will not be available unless (A) a public trading market then exists for the Common Stock of the Company, (B) adequate information concerning the Company is then available to the public, and (C) other terms and conditions of Rule 144 or any exemption therefrom are complied with, and (ii) any sale of the shares of vested Restricted Stock hereunder may be made only in limited amounts in accordance with the terms and conditions of Rule 144 or any exemption therefrom.
