A. The Corporation maintains the Smart Sand, Inc. 2012 Equity Incentive Plan, as amended to date (the “Plan”), for the
benefit of its employees, directors and consultants. Except as otherwise specified herein or unless the context herein requires otherwise, capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the
Plan. 
 B. The Plan permits awards of Restricted Stock subject to the terms of the Plan. 

Agreement 
 NOW,
THEREFORE, in consideration of these premises and the agreements set forth herein, the parties, intending to be legally bound hereby, agree as follows: 

1. Grant of Shares. Subject to the terms and conditions hereof, the Corporation hereby agrees to grant to the Grantee, and the Grantee
hereby agrees to accept from the Corporation,                     (    ) share of the Restricted Stock (the
“Shares”). Subject to the terms and conditions hereof, and simultaneously with the execution of this Agreement, or as soon thereafter as is practicable (such date, the “Effective Date”), the
Corporation will deliver to the Grantee a certificate(s) representing the Shares being granted to the Grantee in exchange for: (a) the Grantee’s delivering to the Corporation an executed Stockholder Rights Agreement or joinder thereto, as
applicable; (b) the aggregate purchase price of the Shares, based on a per Share purchase price of $                    ; (c) an
executed Market Standoff Agreement in the form of Exhibit A hereto (the “Market Standoff Agreement”); and (d) an irrevocable proxy in the form of Exhibit B hereto (the “Proxy”)
pursuant to which the Grantee shall grant to the Chief Executive Officer of the Corporation or the Chief Executive Officer’s designee, the power to vote all Shares that are not “Vested Shares” (as hereinafter defined). Payment of the
purchase price shall be by cash, or certified or bank check or such other consideration and method of payment as may be authorized by the Board pursuant to the Plan. The certificate(s) for the Shares shall be registered in the name of the Grantee
and shall be legended as required under the Plan, this Agreement, the Market Standoff Agreement and/or applicable law. The term “Shares” refers to the Shares granted hereunder and all securities received in replacement of the
Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities or other properties to which the
Grantee is entitled by reason of the Grantee’s ownership of the Shares. 

 2. Vesting of Shares. 

(a) Vesting. The Shares being granted to the Grantee shall vest as follows: 

(i)
                    (        ) Shares on
                    ; 

(ii)
                    (        ) Shares on
                    ; 

(iii)
                    (        ) Shares on
                    ; and 

(iv)
                    (        ) Shares on
                     (in each such case, the “Vested Shares”). 

(b) Vesting Upon Change of Control. Notwithstanding the vesting schedule set forth in Section 2(a), if a Change of Control
involving the Corporation occurs prior to all of the Shares becoming Vested Shares, all of the Shares which have not theretofore become Vested Shares shall immediately and automatically become Vested Shares as of the effective date of the Change of
Control. 
 3. Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws, the
Grantee shall not sell, assign, transfer, encumber or dispose (collectively, “Transfer”) of any interest in Shares that are not Vested Shares. After any Shares have become Vested Shares, the Grantee shall not Transfer any
interest in such Shares except in compliance with the terms and conditions of the Stockholder Rights Agreement or any other applicable Stockholders’ Agreement and applicable securities laws. 

4. Repurchase Option. 

(a) The occurrence of any of the following events shall be considered to be a “Terminating Event”: 

(i) The death of the Grantee; 

(ii) The disability of the Grantee; 

(iii) The dissolution of the marriage of the Grantee, the legal separation between the Grantee and the Grantee’s spouse, or the execution
of a property agreement between the Grantee and the Grantee’s spouse, under any of which events that Grantee’s spouse, or such spouse’s personal representative, heirs, distributes, beneficiaries, trustees or other successors become
the owner of legal title to any of the Shares held by such Grantee (collectively, the “Stockholder’s Successors”); 

(iv) The filing of a voluntary petition in bankruptcy for the Grantee, the adjudication of the Grantee as bankrupt, or an assignment for the
benefit of the creditors of the Grantee; 
 (v) The attempted Transfer of all or any portion of Shares by a Grantee, other than as expressly
permitted under this Agreement; 

  
 2 

 (vi) The Grantee’s ceasing to be employed by or actively engaged as a consultant to or
director of the Corporation or an affiliate of the Corporation, as the term “affiliate” is defined in Section 12b-2 of the Securities Exchange Act of 1934, as amended, including entities in which a majority-in-interest of the
stockholders of the Corporation own a majority-in-interest (hereinafter, “Affiliates”); 
 (vii) a material breach
by the Grantee of this Agreement, the Stockholder Rights Agreement, or any other Stockholders’ Agreement, in each case as determined by the Board in its sole and absolute discretion, which breach is not curable or, if curable, is not cured
within thirty (30) days after notice of such breach from the Corporation to the Grantee; or 
 (viii) while employed by the Company or
any of its Affiliates or within a period of twelve (12) months thereafter, a breach by the Grantee of that certain Employee Nondisclosure, Nonsolicitation, Noncompetition and Assignment Agreement or any similar agreement by and between the
Grantee and the Corporation, in each case as determined by the Board in its sole and absolute discretion (a “Restrictive Covenant Breach”) 

(b) Upon the occurrence of a Terminating Event, notwithstanding anything to the contrary in the Stockholder Rights Agreement or any other
applicable Stockholders’ Agreement, including any rights of first refusal contained therein: (i) all or any portion of the Shares that are not Vested Shares (the “Unvested Shares”) held by the Grantee, shall
thereupon be forfeited and automatically transferred to and reacquired by the Corporation at no cost to the Corporation; and (ii) the Corporation shall have the option (the “Option”), but not the requirement, to purchase
all or any portion of the Shares that are Vested Shares owned by the Grantee or any party who acquires the Vested Shares from, by or through the Grantee, at the time of such Terminating Event, for the price and upon the terms and conditions
specified in this Section 4. The Option shall be exercisable for a period of ninety (90) days from the later of the date of the Terminating Event, or the date on which the Corporation receives written notice of such Terminating Event. The
Option shall be exercisable by providing the Grantee or any party who acquires the Vested Shares from, by or through the Grantee, as applicable, with written notice within such ninety (90) day period of the Corporation’s intention to
exercise the Option, and the number of shares the Corporation elects to purchase. 
 (c) Notwithstanding anything to the contrary in this
Agreement, the Corporation may assign any of its rights under this Section 4, provided that such assignee or assignees otherwise comply with the terms of this Agreement. 

(d) In the event of a Terminating Event, the per share purchase price at which the Corporation or its assignee(s) shall have the option to
purchase all or a portion of the Vested Shares owned by the Grantee or any party who acquires the Vested Shares from, by or through the Grantee, (the “Per Share Purchase Price”) will be the fair market value of a Share at the
time of the Terminating Event; provided, however, that if the Terminating Event results from a Restrictive Covenant Breach, the Per Share Purchase Price shall be equal to the lesser of (i) the fair market value of a Share at the
time of the Terminating Event or (ii) the amount, if any, paid by the Grantee in cash to the Corporation to purchase such Vested Shares. The fair market value of a Share at the time of a Terminating Event will be determined in good faith by the
Corporation’s Board of Directors with the Grantee or and any designee of such person that is a member of the Corporation’s Board of Directors abstaining from any such determination). 

  
 3 

 (e) In the event of the purchase by the Corporation of Vested Shares of the Grantee or any party
who acquires the Vested Shares from, by or through the Grantee upon a Terminating Event, the aggregate purchase price for such Vested Shares (the “Purchase Price”) shall be the Per Share Purchase Price multiplied by the
number of Vested Shares being purchased by the Corporation. The Purchase Price may be paid (i) in cash; (ii) by offset of any obligation of the Grantee, or any party who acquires the Vested Shares from, by or through the Grantee, to the
Corporation or its Affiliates; or (iii) pursuant to an unsecured, subordinated promissory note of the Corporation with a five-year term (or such longer period as may be required by any financing agreement to which the Corporation is a party)
yielding the then-current rate of U.S. Treasury Notes with a comparable duration, subject to prepayment by the Corporation without penalty. Notwithstanding the foregoing, the Corporation will in no event be obligated to pay greater than $50,000 in
any one year period under the above referenced promissory note(s). In the event that there is more than one stockholder of the Corporation to whom the Corporation is to pay the purchase price of the sort described in this Section 4 pursuant to
other Restricted Stock Award Agreements or other similar agreements, and the total amount of purchase price to be paid in a year is in excess of the maximum stated above, then the Corporation shall make such payments pro rata to the Grantee or any
party who acquires the Vested Shares from, by or through the Grantee, and such other stockholders of the Corporation based upon the relative proportions of purchase price to be paid to all such persons in such year. Any obligation to pay purchase
price to such persons shall be extended and the Corporation shall not be in default on any such obligation so long as the Corporation continues to pay the maximum amount of purchase price required to be paid under this Section 4(e) to the
Grantee, or any party who acquires the Vested Shares from, by or through the Grantee, and/or other stockholders of the Corporation. The payment of the Purchase Price payable to the Grantee, or any party who acquires the Vested Shares from, by or
through the Grantee, shall be made not sooner than (A) the time, in the opinion of legal counsel for the Corporation, that the Grantee or any party who acquires the Vested Shares from, by or through the Grantee becomes capable of transferring
to the Corporation or its assignee(s) full legal and equitable lien-free title to the Vested Shares, and (B) delivery to the Corporation of the certificates representing the Vested Shares properly endorsed in the manner required to transfer
full legal and equitable lien-free title to those Vested Shares to the Corporation or its assignee(s). 
 (f) At the closing of the purchase
of the Vested Shares, the Grantee , or any party who acquires the Vested Shares from, by or through the Grantee, as applicable, shall deliver to the Corporation a general release in form and substance satisfactory to the Corporation or its
assignee(s), if applicable, and its or their counsel, releasing the Corporation and its assignee(s), if applicable, from and against any and all claims, demands, causes of action, losses, damages, liabilities, costs and expenses arising prior to the
date of such closing (other than the Corporation’s or its assignee’s or assignees’, if applicable, obligation to pay the full purchase price for the Vested Shares). 

5. Escrow of Shares. For purposes of facilitating the enforcement of the provisions of Section 4 above, the Grantee agrees,
immediately upon receipt of the certificate(s) for the Shares subject to the Repurchase Option, to deliver such certificate(s), together with an 

  
 4 

 
Assignment Separate from Certificate in the form attached to this Agreement as Exhibit C executed by the Grantee, in blank, to the Secretary of the Corporation, or the Secretary’s
designee, to hold such certificate(s) and Assignment Separate from Certificate in escrow and to take all such actions and to effectuate all such transfers and/or releases as are in accordance with the terms of this Agreement. The Grantee hereby
acknowledges that the Secretary of the Corporation, or the Secretary’s designee, is so appointed as the escrow holder with the foregoing authorities as a material inducement to make this Agreement and that said appointment is coupled with an
interest and is accordingly irrevocable. The Grantee agrees that said escrow holder shall not be liable to any party hereof (or to any other party). The escrow holder may rely upon any letter, notice or other document executed by any signature
purported to be genuine and may resign at any time. The Grantee agrees that if the Secretary of the Corporation, or the Secretary’s designee, resigns as escrow holder for any or no reason, the Board shall have the power to appoint a successor
to serve as escrow holder pursuant to the terms of this Agreement. 
 6. Investment and Taxation Representations. In connection with
the purchase of the Shares hereunder, the Grantee represents and warrants to the Corporation as follows: 
 (a) The Grantee is aware of the
Corporation’s business affairs and financial condition and has acquired sufficient information about the Corporation to reach an informed and knowledgeable decision to acquire the Shares. The Grantee is purchasing these securities for
investment for the Grantee’s own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. The Grantee
does not have any present intention to transfer the Shares to any Person. 
 (b) The Grantee is an “accredited investor” as that
term is defined in Regulation D, promulgated under the Securities Act of 1933, as amended (the “Securities Act”). 

(c) The Grantee understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of the Grantee’s investment intent as expressed herein. 
 (d)
The Grantee further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. The Grantee further acknowledges and
understands that the Corporation is under no obligation to register the securities. The Grantee understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they
are registered or such registration is not required in the opinion of counsel for the Corporation. 
 (e) The Grantee is familiar with the
provisions of Rule 144 promulgated under the Securities Act, which, in substance, permits limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such
issuer), in a non-public offering subject to the satisfaction of certain conditions. The Grantee understands that the Corporation provides no assurances as to whether the Grantee will be able to resell any or all of the Shares pursuant to Rule 144,
which rules requires, among 

  
 5 

 
other things, that the Corporation be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the
Shares has held the Shares for certain specified time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding the foregoing provisions of this
Section 6(e), the Grantee acknowledges and agrees to the restrictions set forth in Section 6(f) hereof. 
 (f) The Grantee further
understands that in the event all of the applicable requirements of Rule 144 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the
fact that Rules are not exclusive, the staff of the Securities and Exchange Commission has expressed its opinion that Persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144
will have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such Persons and their respective brokers who participate in such transactions do so at their own risk. 

(g) The Grantee understands that the Grantee may suffer adverse tax consequences as a result of the Grantee’s purchase or disposition of
the Shares. The Grantee represents that the Grantee has consulted any tax consultants that the Grantee deems advisable in connection with the purchase or disposition of the Shares and that the Grantee is not relying on the Corporation for any tax
advice. 
 7. Restrictive Legends and Stop-Transfer Orders. 

(a) Legends. The certificate or certificates representing the Shares shall bear the following legends (as well as any legends required
by applicable state and federal corporate and securities laws): 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH PLEDGE, HYPOTHECATION, SALE OR TRANSFER IS EXEMPT THEREFROM UNDER THE SECURITIES ACT AND
APPLICABLE STATE SECURITIES LAWS. 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER,
REPURCHASE RIGHTS, AND/OR FORFEITURE 

  
 6 

 
CONDITIONS AS SET FORTH IN THE SMART SAND, INC. 2012 EQUITY INCENTIVE PLAN, A RESTRICTED STOCK AWARD AGREEMENT, AND/OR A STOCKHOLDER RIGHTS (OR SIMILAR) AGREEMENT(S), COPIES OF WHICH ARE ON FILE
AT THE PRINCIPAL OFFICE OF THE CORPORATION AND WILL BE FURNISHED UPON REQUEST TO THE HOLDER OF RECORD OF THE SHARES REPRESENTED BY THIS CERTIFICATE. 

(b) Stop-Transfer Notices. The Grantee agrees that, in order to ensure compliance with the restrictions referred to herein, the
Corporation may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Corporation transfers its own securities, it may make appropriate notations to the same effect in its own records. 

(c) Refusal to Transfer. The Corporation shall not be required (i) to transfer on its books any Shares that have been sold or
otherwise transferred in violation of any of the provisions of this Agreement, or (ii) to treat as owner of such Shares or to accord the right to vote or pay dividends to any purchaser or other transferee to whom such Shares shall have been so
transferred. 
 8. No Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the
Corporation, or a parent or subsidiary of the Corporation, to employ, engage, or terminate the Grantee, for any reason or for no reason at all, with or without cause. 

9. Withholding. The Corporation reserves the right to withhold, in accordance with any applicable laws, from any consideration payable
or property transferable to the Grantee any taxes required to be withheld by federal, state or local law as a result of the grant or the sale or other disposition of the Shares. Alternatively or if the amount of any consideration payable to the
Grantee is insufficient to pay such taxes or if no consideration is payable to the Grantee, upon the request of the Corporation, the Grantee will pay to the Corporation an amount sufficient for the Corporation to satisfy any federal, state or local
tax withholding requirements applicable to and as a condition to the grant or the sale or other disposition of the Shares. The minimum required withholding obligations may be settled with Vested Shares. 

10. The Plan. The Grantee has received a copy of the Plan, has read the Plan and is familiar with its terms, and hereby accepts the
Shares subject to all of the terms and provisions of the Plan, as amended from time to time. Pursuant to the Plan, the Board is authorized to interpret the Plan and to adopt rules and regulations not inconsistent with the Plan as it deems
appropriate. The Grantee hereby agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under the Plan with respect to the Shares or any Agreement related to such Shares. 

11. Section 83(b) Election. The Grantee understands that Section 83(a) of the Internal Revenue Code of 1986, as amended (the
“Code”), taxes as ordinary income for the difference between the amount paid for the Shares and the Fair Market Value of the Shares as of the date any restrictions on the Shares lapse. In this context,
“restriction” means the vesting of the 

  
 7 

 
Shares as set forth in Section 2 of this Agreement. The Grantee understands that the Grantee may elect to be taxed at the time the Shares are acquired, rather than when and as the
restriction expires, by filing an election under Section 83(b) (an “83(b) Election”) of the Code with the Internal Revenue Service within thirty (30) days from the date of acquisition. Even if the Fair Market Value
of the Shares at the time of the execution of this Agreement equals the amount paid for the Shares, the election must be made to avoid income and alternative minimum tax treatment under Section 83(a) in the future. The Grantee understands that
failure to file such an election in a timely manner may result in adverse tax consequences for the Grantee. The Grantee further understands that an additional copy of such election form should be filed with the Grantee’s federal income tax
return for the calendar year in which the date of this Agreement falls. The Grantee acknowledges that the foregoing is only a summary of the effect of United States federal income taxation with respect to purchase of the Shares hereunder, and does
not purport to be complete. The Grantee further acknowledges that the Corporation has directed the Grantee to seek independent advice regarding the applicable provisions of the Code, and the income tax laws of any municipality, state or foreign
country in which the Grantee may reside. 
 The Grantee agrees that the Grantee will execute and deliver to the Corporation with this
executed Agreement a copy of the Acknowledgment and Statement of Decision Regarding Section 83(b) Election (the “Acknowledgment”) attached hereto as Exhibit D. The Grantee further agrees that the Grantee will
execute and submit with the Acknowledgment a copy of the 83(b) Election attached hereto as Exhibit E if the Grantee has indicated in the Acknowledgment its decision to make such an election. 

12. Miscellaneous. 
 (a)
Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of Delaware, without giving
effect to principles of conflicts of law. 
 (b) Entire Agreement; Enforcement of Rights. This Agreement sets forth the entire
agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective
unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 

(c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded, and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 

(d) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the parties hereto and their
respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 

  
 8 

 (e) Counterparts. This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original and all of which together shall constitute one instrument. 
 (f) Successors and Assigns. The
rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Corporation’s successors and assigns. The rights and obligations of the Grantee under this Agreement may only be assigned with the prior written
consent of the Corporation.

(including, but not limited to Smart Sand, LLC) regarding the matters addressed herein including, but not limited to, that specific Employment Agreement between Executive and Smart Sand LLC dated July 13, 2011 (collectively the
“Prior Agreements”).

 6. Termination. 

(a) For Cause. The Company shall have the right, at any time effective upon notice to Executive, to terminate the
Executive’s employment hereunder for “Cause” (as hereinafter defined). For purposes of this Agreement, “Cause” shall mean (i) a documented repeated and willful failure by the Executive to
perform his duties, (ii) Executive’s conviction or entry of a plea of nolo contendere for fraud, misappropriation or embezzlement, or any felony or crime of moral turpitude (iii) willful material violation of a policy
which is directly and materially injurious to the Company or any subsidiary of the Company, and (iv) Executive’s material breach of this Agreement. With respect to subsections 6(a) (i), (iii) and (iv) above, Cause shall exist
only after written notice of such failure, violation or breach is delivered to Executive and Executive shall have failed to cure such violation or breach within 30 days after such notice, if curable. For purposes of this definition, no act or
failure to act on the part of the Executive shall be considered “willful” unless done or omitted not in good faith and without reasonable belief that the action or omission was in the best interest of the Company or any of its Subsidiaries
or Affiliate. 
 (b) Good Reason. Executive shall have the right, at any time upon notice to the Company, to terminate
this Agreement and Executive’s employment hereunder for “Good Reason” (as hereinafter defined) in the event the Executive provides notice to the Company of the Good Reason condition within ninety (90) days after the
initial existence thereof and the Company fails to cure such condition within thirty (30) days of the receipt of notice. For purposes of this Agreement, “Good Reason” means (in the absence of written consent thereto by
the Executive) (i) material diminution by the Company of Executive’s authority, duties and responsibilities, which change would cause Executive’s position to become one of less responsibility, importance and scope, (ii) material
reduction by the Company of the Base Salary, unless such reduction is a result of a reduction of salaries to all employees of the Company and the reduction of Executive’s salary is not greater, on a percentage basis, than the average of the
salary reductions (which shall be measured on a percentage basis) imposed on the other employees of the Company. 
 (c)
Death and Disability. The Executive’s employment will terminate upon his death. The Executive’s employment may be terminated by the Company upon forty-five (45) days written notice from the Company following the determination,
as set forth immediately below, that the Executive suffers from a Permanent Disability. For purposes of this Agreement, “Permanent Disability” means either (i) the inability of Executive to engage in substantial gainful
activity by reason of a medically determinable physical or mental impairment that can be reasonably expected to result in death or can be reasonably expected to last for a continuous period of not less than four (4) months or

receiving income replacement benefits for a period of not less than three (3) months under an accident and health plan covering employees of the Company. Such Permanent Disability shall be certified by a

  
 4 

 
physician chosen by the Company and reasonably acceptable to the Executive (if he is then able to exercise sound judgment) or Executive’s designee. During ‘any period that the Executive
fails to perform his Duties hereunder as a result of a Permanent Disability (“Disability Period”), but prior to termination of employment, the Executive will continue to receive his Base Salary at the rate then in effect for
such period until his employment is terminated pursuant to this Section 6(c); provided, however, that payments of Base Salary so made to the Executive will be reduced by the sum of the amounts, if any, that are or were payable to the Executive
under any disability benefit plan or plans of the Company and that were not previously applied, and such payments will be made in accordance with the Company’s standard payroll practices for salaried employees (but no less frequently than twice
a month).

the termination date occurs, (iii) accrued but unused (as of the termination date) vacation pay and (iv) approved and unreimbursed (as of the termination date) business expenses. Notwithstanding any provision of this Agreement to the
contrary, Standard Entitlements shall include employee benefits that by their terms continue after the termination of employment; provided, however, that, employee benefits, if any, provided after the termination date shall be so provided in
accordance with the schedule applicable thereto. For purposes of this Agreement, the schedules described in this Section 7(a) shall be referred to as the “Standard Entitlements Payment Schedule.” Once the Standard
Entitlements have been paid to the Executive, the Company shall have no further obligation to Executive. 
 (b) If Executive
shall die during the Term, then: (i) the Company shall pay to Executive’ estate the Base Salary specified in Section 5(a) in separate, substantially equal monthly installments until the earlier to occur of (A) the date which is

(ii) Executive’s Estate shall be paid, in a single lump sum on March 1 of the year following the calendar year during which Executive’s date of death occurs, an amount equal to the Base Salary that would have been paid to

Entitlements Payment Schedule and a “Severance Payment” equal to the Base Salary specified in Section 5(a) due for a period equal to the greater of (x) twelve months or (y) the number of months remaining in the
Initial Period or Renewal Period, as applicable, in separate, substantially equal monthly installments until the earlier to occur of (A) the date which is twelve (12) months from the termination date, or (B) the date upon which the
monthly installment is payable to Executive in February of the year immediately following the calendar year during which Executive’s employment terminated; and (ii) Executive shall be paid, in a single lump sum on March 1 of the year

terms prior to the 60th day following the termination date (“Release”). All other Company obligations to Executive will be automatically terminated and completely extinguished. Anything herein to the contrary notwithstanding,
the payments to Executive set forth in Sections 7(c)(i) and 7(c)(ii) shall be made in accordance with the short-term deferral exception under Treasury Regulations section 1.409A-1(b)(4). Anything herein to the contrary notwithstanding, non-renewal
of the Executive’s employment hereunder after the expiration of the Initial Term or any Renewal Period and the election pursuant to Section 2 to terminate the Agreement at the expiration of a Term shall not be considered a termination of
this Agreement by Company without Cause or by Executive for Good Reason. For purposes of this Agreement, a “Change of Control” of the Company shall be deemed to have occurred at any such time as there is a direct or indirect
change of more than 50% from that thereof on the Effective Date in the (a) equity ownership (on a fully-diluted basis), or (b) voting control (based on equity ownership, contract, or otherwise), of the Company or any material Subsidiary,

(iii) Executive shall receive the Disability Severance if, and only if, Executive (or a duly authorized representative of Executive is due to incapacity, Executive is unable to execute such a Release) and Company execute a Release. Anything
herein to the contrary notwithstanding, the payments to Executive set forth in Sections 7(c)(i) and 7(c)(ii) shall be made in accordance with the short-term deferral exception under Treasury Regulations section 1.409A-1(b)(4). 

(e) Executive’s obligations pursuant to Sections 8 and 10 hereof shall survive any termination of this Agreement for any
reason whatsoever.

all other positions Executive may hold on behalf of Company.

Company is now engaged or in which Company becomes engaged during the term of Executive’s employment with Company, as may be determined by the Board of Directors in its sole discretion. If the Board of Directors believes such a conflict exists
during the term of this Agreement, the Board of Directors may ask Executive to choose to discontinue the other work and/or activities or resign employment with Company. 

9. Confidentiality. 

(a) Executive may now and in the future have access to, and may be given information with respect to the following
non-exhaustive list of information, not known to the public or a competitor, and creative works, regardless of their stage of respective development, relating to the Company or any of its affiliates: trade secrets, patents, non-public trademarks,
non-public copyrights and any non-public application for registration thereof; business and marketing plans and strategies; advertising and pricing strategies; accounting and business methods; existing and prospective customer, vendor, employee and
consultant lists; the confidential information of customers, members, and vendors; 

  
 7 

 
inventions, discoveries, innovations, processes, methodologies, concepts, formulas, algorithms and devices; computer software, including system software, application software and firmware,

works (the “Confidential Information”) that are part of or used or useful or being developed for use in the Business of the Company or affiliates, which is not generally known to the public and gives the Company an advantage
over its respective competitors who do not know or use the. Confidential Information. Executive acknowledges that all of such Confidential Information as it now or in the future exists: 

(1) Belongs to the Company, its members, subsidiaries and affiliates; 

(2) Constitutes specialized and highly confidential information not generally known in the industry; and 

(3) Constitutes a valuable asset of the Company. 

Accordingly, Executive recognizes and acknowledges that it is essential to the Company to protect the confidentiality of such Confidential Information. 

(b) Executive agrees to act as a trustee of such Confidential Information and of any other confidential information he acquires
in connection with his association with the Company. Further, as an inducement to the Company to retain him as an executive, he will hold all such Confidential Information, in trust and confidence for the use and benefit solely of the Company. 

(c) Executive agrees to refrain from divulging or disclosing any Confidential Information to others and from using such
Confidential Information, except for the benefit of the Company as contemplated hereunder. 
 (d) Upon Executive’s
Employment Termination, Executive shall deliver, or cause to be delivered in the case of termination because of incapacity, to the Company all documents and data of any nature pertaining to his work with the Company. Executive shall not take any
documents or data of any description or any reproduction of any description containing or pertaining to any Confidential Information. 

  
 8 

 (e) The confidentiality provisions of this Section 8 are intended to
supplement and not supersede the applicable provisions of the Uniform Trade Secrets Act, to the fullest extent applicable. 

(f) During the Term hereof, and thereafter, Executive shall not disclose such Confidential Information to any person, firm,
association, or other entity for any reason or purpose whatsoever, unless such information has already become common knowledge or unless Executive is required to disclose it by judicial process. Executive shall notify the Company in writing of such
judicial process prior to disclosure, and allow the Company a reasonable opportunity to defend and protect its rights therein. 
 10.
Warranty Against Prior Existing Restriction. The parties agree that Executive is not and will not be a party to any agreement with any person, entity, firm, or business organization which directly or indirectly competes with the
Business of the Company (a “Competitive Business”), containing anon-competition clause or other restriction with respect to the services which he is required to perform hereunder. 

11. Restrictive Covenants. Executive agrees that for a period of twelve (12) months after separation of employment or the
termination of Executive’s employment for any reason whatsoever, including but not limited to expiration of the Term, and provided that the Company has paid or provided to Executive all of the Standard Entitlements and the full amount of any
Severance Payment or any Disability Severance required under this Agreement: 
 (a) Executive shall not, directly or
indirectly, anywhere in United States, engage in activities for, nor render services (similar or reasonably related to those which Executive shall have rendered to the Company) to a Competitive Business, whether now existing or hereafter
established, nor shall Executive entice, induce or encourage any of the Company’s employees to engage in any activity which, were it done by Executive, would violate any provision of this section. 

(b) Executive shall not, directly or indirectly, anywhere in United States, own, manage, operate, or control, or participate or
engage in, a Competitive Business, whether now existing or hereafter established, for his own account or for the benefit of any other person, in any capacity, whether as a proprietor, partner, owner, member, shareholder, creditor, investor, joint
venturer, officer, director, consultant, agent or otherwise; provided, however, that Executive may own not more than 5% of the outstanding securities of a publicly traded entity as a passive investment only and so long as Executive does not
participate in the management, operation or control of such entity. 
 (c) Executive shall not, directly or indirectly,
endeavor to entice or solicit the Company’s employees or independent contractors to leave their employ or engagement with the Company or its affiliates. Further, Executive shall not solicit, recruit, hire, or offer or cause to be offered
employment or a contract to any person who was employed by or under contract with respect to the Company at any time during the eighteen (18) months prior to the termination of his employment with the Company. 

  
 9 

 (d) The parties acknowledge that they have attempted to limit Executive’s
right to compete only to the extent necessary to protect the Company from unfair competition. However, the parties hereby agree that, if the scope or enforceability of the restrictive covenant is in any way disputed at any time, a court or other
competent trier of fact may modify and enforce the covenant to the extent that it finds the covenant to be reasonable under the circumstances existing at the time. 

(e) Executive further acknowledges that: (A) in the event this Agreement terminates for any reason, he will be able to
earn a livelihood without violating the foregoing restrictions; and (B) that his ability to earn a livelihood without violating such restrictions is a material condition to his retention by the Company. 

(f) The provisions of, and the Executive’s duties under, this Section 11 shall survive termination of this Agreement.
Executive acknowledges that a remedy at law for any breach or threatened breach by Executive of this Section 11 may be inadequate, and Executive therefore agrees that the Company shall be entitled to all available remedies in law including
injunctive relief in case of any such breach or threatened breach. 
 12. Severability. It is the desire and intent of the
parties hereto that the provisions of this Agreement shall be enforced to the fullest extent permissible under the laws and public policy of each jurisdiction in which enforcement is sought. Accordingly, if any particular provision, section, or
subsection of this Agreement is adjudged by any court of law to be void or unenforceable, in whole or in part, such adjudication shall not be deemed to affect the validity of the remainder of the Agreement, including any other provision, section, or
subsection. In addition, if any one or more of the provisions contained in this Agreement shall for any reason be held to be excessively broad as to duration, geographical scope, activity or subject, it shall be construed by limiting and reducing

 15. Non-waiver. No delay or failure by either party to exercise any right under
this Agreement, and no partial or single exercise of that right, shall constitute a waiver of that or any other right, unless otherwise expressly provided herein or otherwise in a written agreement from the applicable party. 

16. Headings. Headings in this Agreement are for convenience only and shall not be used to interpret or construe its provisions.

 17. Governing Law. This Agreement shall be construed in accordance with and governed by the internal laws of the
Commonwealth of Pennsylvania (without regard to its principles in respect of conflicts of laws). 
 18. Counterparts. This
Agreement may be executed in one or more counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same instrument. 

19. Remedies. The parties agree that in addition to any other rights and remedies available to the Company for any breach by
Executive of his obligations hereunder, the Company shall be entitled to enforce Executive’s obligations hereunder by court injunction, or court ordered affirmative action, which injunction or ordered action may restrain a future breach of this
Agreement if there is reasonable ground to believe that such a breach is threatened. Executive further agrees to allow the Company to enjoin future use or disclosure of its Confidential Information if it has reasonable grounds to believe such action
is necessary to protect such Confidential Information. 
 20. Attorney’s Fees. In the event of any alleged dispute,
breach or default under the terms of this Agreement by either party, the prevailing party shall be entitled to recover all costs and expenses, including reasonable attorneys’ fees, incurred in such litigation, and such right shall be in

 21. Prohibition Against
Assignment. Executive agrees, for himself and on behalf of his successors, heirs, executors, administrators, and any person or persons claiming under him by virtue hereof, that this Agreement and the rights, interests, and benefits hereunder
cannot be assigned, transferred, pledged, or hypothecated in any way by Executive and shall not be subject to execution, attachment, or similar process. Any such attempt to do so, contrary to the terms hereof, shall be null and void and shall
relieve the Company of any and all obligations or liability hereunder. The rights and obligations of Company under this Agreement shall inure to the benefit of and shall be binding upon the successors and assigns of Company. 

22. Taxes. Any payments made pursuant to this Agreement shall be subject to any tax or similar withholding requirements under
applicable federal, state or local employment or 

  
 11 

 
income tax laws or similar statutes or other provisions of law then in effect. This Agreement is intended to comply with the requirements of Section 409A of the Code and the regulations
thereunder (together “Section 409A”). To the extent that any provision in this Agreement is ambiguous as to its compliance with Section 409A, the provision shall be interpreted in a manner so that no payment due to
Executive hereunder shall be deemed subject to an “additional tax” within the meaning of Section 409A(a)(1)(B) of the Code. For purposes of Section 409A, each payment made under this Agreement shall be treated as a separate
payment. In addition, the right to a series of installment payments under this Agreement is to be treated as a right to a series of separate payments. Notwithstanding anything contained herein to the contrary, Executive shall not be considered to
have terminated employment with the Employer for purposes of this Agreement unless Executive has incurred a “termination of employment” from the Employer within the meaning of Treasury Regulation § 1.409A-1(h)(1)(ii) promulgated under
Section 409A (applied by using the default rules contained therein) and in no event may a payment be made under Section 7 unless the Executive has incurred a “separation from service” from the Employer within the meaning of
Treasury Regulation §1.409A-1(h)(1)(i) promulgated under Section 409A (applied by using the default rules contained therein). For purposes of this Section 22, “Employer” means the Company and any entity
required to be aggregated with the Company under Treasury Regulation §1.409A-1(h)(3) promulgated under Section 409A (applied by using the default rules contained therein). Notwithstanding the foregoing, if applicable and necessary to
comply with the restriction in Section 409A(a)(2)(B) of the Code concerning payments to “specified employees,” any payment made to Executive pursuant to this Agreement on account of the Employee’s separation from service that
would otherwise be due hereunder within six (6) months after such separation from service shall nonetheless be delayed until the first business day of the seventh (7th) month following Executive’s separation from service (or, if
earlier, the date of his death). The first payment that can be made to the Executive following such period shall include the cumulative amount of any payments or benefits that could not be paid or provided during such period due to the application
of Code Section 409A(a)(2)(13)(i). In no event may Executive, directly or indirectly, designate the calendar year of any payment or accelerate the payment of any amount that constitutes deferred compensation under Section 409A. All
reimbursements provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A, including, where applicable, the requirement that (i) any reimbursement is for expenses incurred during
Executive’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other
calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred, and (iv) the right to reimbursement is not subject to
liquidation or exchange for another benefit. Executive further acknowledges that, while this Agreement is intended to comply with Section 409A, any tax liability incurred by Executive under Section 409A is solely the responsibility of
Executive; provided, however, that in the event. Executive is assessed any interest, penalty and/or additional tax under Section 409A(a)(1)(B) as a result of a failure of the shares underlying any options granted to the Executive to qualify as
service recipient stock under Section 409A, then the Company shall indemnify the Executive for all such penalties, additional taxes and interest, and federal, state and local income taxes incurred by the Executive as a result of such
indemnification. Any such indemnification shall take the form of a tax gross-up payment, which shall be made no later than December 31st of the year immediately following the year in which
the applicable taxes are remitted by the Executive to the Internal Revenue Service.

 23. Arbitration. In the event of any dispute or claim relating to or arising out of the
employment relationship between Executive and Company (other than a dispute or claim relating to or arising out of the Confidentiality Agreement) or the termination of that relationship (including, but not limited to, any claims of breach of
contract, wrongful termination or age, sex, race, disability or other discrimination), Executive and Company agree that all such disputes shall be resolved by binding arbitration conducted before a single neutral arbitrator in Philadelphia,
Pennsylvania, pursuant to the rules for arbitration of employment disputes by the American Arbitration Association (available at www.adr.org). The arbitrator shall permit adequate discovery. In addition, the arbitrator is empowered to award all
remedies otherwise available in a court of competent jurisdiction; however Executive and Company each retain the right under to seek provisional remedies. Any judgment rendered by the arbitrator may be entered by any court of competent jurisdiction.
The arbitrator shall issue an award in writing and state the essential findings and conclusions on which the award is based. By executing this Agreement, Executive and Company are both waiving the right to a jury trial with respect to any such
disputes. Each party shall bear its own respective attorneys’ fees and all other costs, unless otherwise provided by law and awarded by the arbitrator. This arbitration agreement does not include claims that, by law, may not be subject to
mandatory arbitration. 
 IN WITNESS WHEREOF, the Parties have duly executed this Agreement as of the date first written above.
