Preamble 

Concurrently with the execution and delivery hereof, Buyer, Target and certain owners of membership interests of Target (the “Target
Owners”) are entering into an acquisition agreement of even date herewith (as it may be amended or supplemented from time to time pursuant to the terms thereof, the “Transaction Agreement”), which provides for the
acquisition by Buyer (the “Transaction”) of all of the outstanding ownership interests of Target by Buyer such that following the closing of the Transaction, Target will be a wholly-owned subsidiary of Buyer. 

Each Stockholder is the beneficial owner (as defined in Rule 13d-3 under the Exchange Act) of such number of shares of each class of capital
stock of Buyer as is indicated on the signature page of this Agreement. 
 In consideration of the execution and delivery of the Transaction
Agreement by Buyer, Target and the Target Owners, Stockholders desire to agree to vote the Shares (as defined herein) over which Stockholder has voting power so as to facilitate the consummation of the Transaction, as further provided herein. 

NOW, THEREFORE, intending to be legally bound, the parties hereto hereby agree as follows: 

1. Certain Definitions. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed thereto in the
Transaction Agreement. For all purposes of and under this Agreement, the following terms shall have the following respective meanings: 

“Constructive Sale” means with respect to any security a short sale with respect to such security, entering into or acquiring
an offsetting derivative contract with respect to such security, entering into or acquiring a futures or forward contract to deliver such security or entering into any other hedging or other derivative transaction that has the effect of either
directly or indirectly materially changing the economic benefits and risks of ownership. 
 “Shares” means, with respect to
any Stockholder, (i) all shares of capital stock of the Company owned, beneficially or of record, by each Stockholder as of the date hereof which are entitled to vote at any meeting of stockholders generally or upon written consent in lieu of a
meeting or to vote as a separate class upon the Transaction, and (ii) all additional shares of capital stock which are entitled to vote at any meeting of stockholders generally or upon written consent in lieu of a meeting or to vote as a
separate class upon the Transaction of the Company acquired by Stockholder, beneficially or of record, during the period commencing with the execution and delivery of this Agreement and expiring on the Expiration Date (as such term is defined in
Section 12 below).

security (including transfers by testamentary or intestate succession or otherwise by operation of law) or any right, title or interest therein (including, but not limited to, any right or power to vote to which the holder thereof may be entitled,
whether such right or power is granted by proxy or otherwise), or the record or beneficial ownership thereof, the offer to make such a sale, transfer, Constructive Sale or other disposition, and each agreement, arrangement or understanding, whether
or not in writing, to effect any of the foregoing.

with respect thereto. 
 (b) Each Stockholder understands and agrees that if such Stockholder attempts to Transfer, vote or provide any
other person with the authority to vote any of the Shares owned by such Stockholder other than in compliance with this Agreement, Buyer shall not, and each Stockholder hereby unconditionally and irrevocably instructs Buyer not to, (i) permit
any such Transfer on its books and records, (ii) issue a new certificate representing any of the Shares owned by such Stockholder or (iii) record such vote unless and until such Stockholder shall have complied with the terms of this
Agreement. 
 (c) From and after the date hereof, except as otherwise permitted by this Agreement or by order of a court of competent
jurisdiction, each Stockholder will not commit any act that would restrict his legal power, authority and right to vote all of the Shares then owned of record or beneficially by him or otherwise prevent or disable such Stockholder from performing
any of his obligations under this Agreement. Without limiting the generality of the foregoing, except for this Agreement and as otherwise permitted by this Agreement, from and after the date hereof, each Stockholder will not enter into any voting

3. Agreement to Vote Shares. 

(a) Prior to the Expiration Date, at every meeting of the stockholders of Buyer called, and at every adjournment or postponement thereof, and

 (b) If
Stockholder is the beneficial owner, but not the record holder, of the Shares, such Stockholder agrees to take all actions necessary to cause the record holder and any nominees to vote all of the Shares in accordance with this Section 3.
