I. AGREEMENT TO VOTE

1.1 Voting Agreement. (a) Chucktaylor hereby covenants and agrees that, prior to the Expiration Date, at any meeting (whether annual or special and whether or not an adjourned or postponed meeting) of the stockholders of Victory, however called, unless otherwise directed in writing by Victory (with the approval of the Special Committee), Chucktaylor will appear at the meeting or otherwise cause the Shares to be counted as present thereat for purposes of establishing a quorum and to vote or cause the Shares to be voted (i) in favor of (A) the issuance of Victory Common Stock pursuant to the Merger, (B) the adoption of the Merger Agreement, (C) authorizing the Transactions, and (D) to the extent that a vote is solicited in connection with this Agreement or the Merger Agreement, any other action required in furtherance hereof or thereof and (ii) against any action that would preclude fulfillment of a condition precedent under the Merger Agreement to Victory’s, Chucktaylor’s or Merger Sub’s obligation to consummate the Merger or the other Transactions.

(b) Prior to the Expiration Date, Chucktaylor will not enter into any agreement or understanding with any person to vote or give instructions in any manner inconsistent with any provision of this Section 1.1. This Agreement is intended to bind Chucktaylor only with respect to the specific matters set forth herein.

1.2 Irrevocable Proxy. Chucktaylor hereby irrevocably grants to and appoints Peter Fante and Dan Bodner, in their respective capacities as officers of Victory, and any individual who shall hereafter succeed to any such office of Victory, and each of them individually, Chucktaylor’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of Chucktaylor, to represent, vote and otherwise act (by voting at any meeting of stockholders of Victory) with respect to the Shares owned or held by Chucktaylor regarding the matters referred to in Section 1.1(a) hereof until the Expiration Date, to the same extent and with the same effect as Chucktaylor might or could do under applicable law, rules and regulations. The proxy granted pursuant to this Section 1.2 is coupled with an interest and shall be irrevocable until the Expiration Date. Chucktaylor will take such further action and will execute such other instruments as may be necessary to effectuate the intent of this proxy. Chucktaylor hereby revokes any and all previous proxies or powers of attorney granted with respect to any of the Shares that may have heretofore been appointed or granted with respect to the maters referred to in Section 1.1(a) hereof and no subsequent proxy (whether revocable or irrevocable) or power of attorney shall be given by Chucktaylor.

1.3 Transfer and Other Restrictions. (a) From and after the date hereof until the termination of this Agreement, Chucktaylor agrees not to, directly or indirectly:

(i) grant any proxy, power of attorney, deposit any Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Shares except as provided in this Agreement; or

(ii) take any other action that would make any representation or warranty of Chucktaylor contained herein untrue or incorrect or, except as permitted by the Merger Agreement, have the effect of preventing or disabling Chucktaylor from performing its obligations under this Agreement.

(b) To the extent that Chucktaylor is, as of the date hereof or becomes, prior to the Expiration Date, party to a contract or agreement that requires Chucktaylor to Transfer any Shares to another person or entity, Chucktaylor will not effect any such Transfer unless, prior to such Transfer, Chucktaylor causes the transferee to be bound by and to execute an agreement in the form of this Agreement with respect to the Shares to be Transferred.

(c) Chucktaylor agrees with, and covenants to, Victory that Chucktaylor will not request that Victory register the transfer (book-entry or otherwise) of any certificate or uncertificated interest representing any Shares, unless such transfer complies with Section 1.3(b).

2

(d) Victory acknowledges that Chucktaylor is party to the Cadian Agreement and no action taken in accordance with the requirements thereby shall constitute a violation of this Agreement.

5

any interest in this Agreement will be deemed effective to modify, amend or discharge any part of this Agreement or any rights or obligations of any Party under or by reason of this Agreement.

(b) No delay or failure in exercising any right, power or remedy hereunder will affect or operate as a waiver thereof; nor will any single or partial exercise thereof or any abandonment or discontinuance of steps to enforce such a right, power or remedy preclude any further exercise thereof or of any other right, power or remedy. The rights and remedies hereunder are cumulative and not exclusive of any rights or remedies that any Party hereto would otherwise have. Any waiver, permit, consent or approval of any kind or character of any breach or default under this Agreement or any such waiver of any provision of this Agreement must satisfy the conditions set forth in Section 4.2(a) and will be effective only to the extent in such writing specifically set forth.

4.3 No Third-Party Beneficiaries. This Agreement is solely for the benefit of the Parties and does not confer on third parties any remedy, claim, reimbursement, claim of action or other right in addition to those existing without reference to this Agreement.

Each of the Parties irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any dispute arising out of this Agreement or any of the Transactions in the state and federal courts of the State of Delaware, or that any such dispute brought in any such court has

6

been brought in an inconvenient or improper forum. The Parties further agree that the mailing by certified or registered mail, return receipt requested, of any process required by any such court will constitute valid and lawful service of process against them, without necessity for service by any other means provided by statute or rule of court.

4.7 Notices. All notices, requests, permissions, waivers and other communications hereunder must be in writing and delivered in accordance with Section 7.05 of the Merger Agreement.

4.8 Specific Performance. The Parties hereby acknowledge and agree that the failure of any Party to perform its agreements and covenants hereunder, including its failure to take all actions as are necessary on its part to the consummation of the Transactions, will cause irreparable injury to the other Parties for which damages, even if available, will not be an adequate remedy. Accordingly, each Party hereby consents to the issuance of injunctive relief by any court of competent jurisdiction to compel performance of such Party’s obligations and to the granting by any court of the remedy of specific performance of its obligations hereunder.

4.9 Counterparts. This Agreement may be executed in multiple counterparts (any one of which need not contain the signatures of more than one Party), each of which will be deemed to be an original but all of which taken together will constitute one and the same agreement. This Agreement, and any amendments hereto, to the extent signed and delivered by means of a facsimile machine or other electronic transmission, will be treated in all manner and respects as an original agreement and will be considered to have the same binding legal effects as if it were the original signed version thereof delivered in person. At the request of any Party, the other Party will re-execute original forms thereof and deliver them to the requesting Party. No Party will raise the use of a facsimile machine or other electronic means to deliver a signature or the fact that any signature was transmitted or communicated through the use of facsimile machine or other electronic means as a defense to the formation of a Contract and each such Party forever waives any such defense.
