2. Voting Restrictions.

(a) Stockholder understands and agrees that if Stockholder attempts to vote or provide any other Person with the authority to vote any of the Shares other than in compliance with this Agreement, the Company shall not, and Stockholder hereby unconditionally and irrevocably instructs the Company to not, record such vote, in each case, unless and until Stockholder shall have complied with the terms of this Agreement.

3

nothing herein shall prohibit the Stockholder or any Clearlake Entity from acquiring voting securities of the Company (i) if after such acquisition the Stockholder or such Clearlake Entity is the Beneficial Owner of less than five percent (5.0%) in the aggregate of the voting securities or direct or indirect rights to acquire any voting securities of the Company or any subsidiary thereof, or of any successor to or Person in control of the Company, or (ii) as the owner of record on behalf of any other Persons (other than, in the case of Stockholder, Stockholder or its Affiliates, and in the case of any Clearlake Entity, any other Clearlake Entities);

(b) make, or in any way participate, directly or indirectly, in any “solicitation” of “proxies” to vote (as such terms are used in the rules of the Securities and Exchange Commission), or seek to advise or influence any Person or entity with respect to the voting of any voting securities of the Company;

(c) make any public announcement with respect to, or submit a proposal for, or offer of (with or without conditions) any extraordinary transaction involving the Company or any of its securities or assets; or

Stockholder will promptly advise the Company of any inquiry or proposal made to Stockholder with respect to any of the foregoing.
