 EXHIBIT A 
 IRREVOCABLE PROXY 
 The undersigned Stockholder (the
“Stockholder”) of EyeWonder, Inc., a Delaware corporation (the “Company”), hereby irrevocably (to the fullest extent permitted by law) appoints Limelight Networks, Inc., a Delaware corporation
(“Parent”), acting through any of its Chief Executive Officer, Chief Financial Officer or Chief Legal Officer, as the sole and exclusive attorneys and proxies of the Stockholder, with full power of substitution and resubstitution,
to vote and exercise all voting and related rights (to the full extent that the Stockholder itself (and not any of its affiliates is entitled to do so)) with respect to all of the shares of capital stock of the Company that now are or hereafter may
be beneficially owned by the Stockholder itself (and not any of its affiliates), and any and all other shares or equity securities of the Company issued or issuable in respect thereof on or after the date hereof (collectively, the
“Shares”) in accordance with the terms of this Irrevocable Proxy until the Expiration Date (as defined below); provided, however, that such proxy and voting and related rights are expressly limited to the matters discussed in
clauses (i) through (iii) in the fourth paragraph of this Irrevocable Proxy. Upon the Stockholder’s execution of this Irrevocable Proxy, any and all prior proxies given by the Stockholder with respect to any Shares are hereby revoked
and the Stockholder agrees not to grant any subsequent proxies with respect to the Shares until after the Expiration Date. 
 This Irrevocable Proxy is irrevocable to the fullest extent permitted by law, is coupled with an interest and is granted pursuant to that certain Voting Agreement of even date herewith by and between Parent and the undersigned Stockholder,
and is granted as a condition and inducement to the willingness of Parent, Elvis Merger Sub One Corporation, a Delaware corporation and a direct, wholly-owned subsidiary of Parent (“Merger Sub One”) and Elvis Merger Sub Two LLC, a

transaction, the merger of Merger Sub One with and into the Company (the “First Step Merger”) in accordance with the applicable provisions of the General Corporations Law of the State of Delaware. As soon as practicable following
the First Step Merger, Parent will cause the Company to merge with and into Merger Sub Two, with Merger Sub Two continuing as the surviving entity (the “Second Step Merger” and, taken together with the First Step Merger, the
“Merger”). 
 As used herein, the term “Expiration Date” shall mean the earlier to occur of
(i) such date and time as the Merger Agreement shall have been validly terminated pursuant to Article IX thereof, (ii) such date and time as the Requisite Company Voting Approval has been obtained, (iii) such date and time as
the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement or (iv) the written agreement of the Stockholder and Parent to terminate the Voting Agreement to which they are parties. 
 The attorneys and proxies named above, and each of them, are hereby authorized and empowered by the Stockholder, at any time prior to the
Expiration Date, to act as the Stockholder’s attorney and proxy to vote the Shares, and to exercise all voting, consent and similar rights of the Stockholder with respect to the Shares (including, without limitation, the power to execute and
deliver written consents) at every annual, special, adjourned or postponed meeting of stockholders of the Company and in every written consent in lieu of such meeting: 
 (i) in favor of the adoption of the Merger Agreement, and in favor of each of the other actions contemplated by the Merger Agreement and any action required in furtherance thereof; 








 CONFIDENTIAL 
  

 (ii) against approval of any proposal made in opposition to, or in competition with, the
Merger Agreement or the Merger or any other transactions contemplated by the Merger Agreement; and 
 (iii) against any of the
following actions (other than those actions that relate to the Merger and any other transactions contemplated by the Merger Agreement): (A) any merger, consolidation, business combination, sale of assets, reorganization or recapitalization of
or involving the Company or any of its Subsidiaries, (B) any sale, lease or transfer of any significant part of the assets of the Company or any of its Subsidiaries, (C) any reorganization, recapitalization, dissolution, liquidation or
winding up of the Company or any of its Subsidiaries, (D) any material change in the capitalization of the Company or any of its Subsidiaries, or the corporate structure of the Company or any of its Subsidiaries, or (E) any other action
that is intended, or could reasonably be expected to, impede, interfere with, delay, postpone, discourage or adversely affect the Merger or any other transactions contemplated by the Merger Agreement. 
 As used herein, the term “Subsidiary” shall mean any entity, including a partnership, a limited liability company, a
corporation, an association, a joint stock company, a trust, a joint venture, or an unincorporated organization (a “Person”), whether or not existing on the date hereof, in which the Company directly or indirectly through
subsidiaries or otherwise, beneficially owns any equity interest, or voting power of or in such Person. 
 The attorneys and
proxies named above may not exercise this Irrevocable Proxy on any other matter. The Stockholder may vote the Shares on all other matters. 
 Any obligation of the Stockholder hereunder shall be binding upon the successors and assigns of the Stockholder.
