(a)   Shares.  The Stockholder is the beneficial owner of, and has good and valid title to, the Shares, free and clear of any liens, claims, options, rights of first refusal, co-sale rights, charges or other encumbrances.  As of the date hereof, Stockholder does not beneficially own or have any written or unwritten agreement or arrangement to acquire any securities of Citadel other than the shares of Citadel Stock and options and warrants to purchase shares of Citadel Stock indicated on the signature page of this Agreement.  The Stockholder has sole voting power, sole power of disposition, sole power to issue instructions with respect to the matters set forth in Sections 2 and 3 hereof, sole power to agree to all of the matters set forth in this Agreement, in each case with respect to all of the Shares, with no limitations, qualifications or restrictions on such rights, subject to applicable federal securities laws and the terms of this Agreement.

3

(c)   Consents and Approvals; No Violations.  Neither the execution, delivery or performance of this Agreement by Stockholder nor the consummation by him of the transactions contemplated hereby nor compliance by him with any of the provisions hereof will (i) (if such Stockholder is an entity) conflict with or result in any breach of any provision of its certificate of formation, operating agreement, by-laws or other charter documents, (ii) require any filing with, or permit, authorization, consent or approval of, any court, administrative agency or commission or other governmental authority or instrumentality (except where the failure to obtain such permits, authorizations, consents or approvals or to make such filings would not materially impair the ability of the Stockholder to consummate the transactions contemplated hereby), (iii) result in a violation or breach of, or constitute (with or without due notice or lapse of time or both) a default (or give rise to any right of termination, amendment, cancellation of acceleration) under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, guarantee, other evidence of indebtedness, lease, license, contract, agreement or other instrument or obligation to which Stockholder is a party or by which he or any his properties or assets may be bound or (iv) as of the date hereof, violate any order, writ, injunction, decree, statute, rule or regulation applicable to him or any of his properties or assets.

(d)   No Finder’s Fee.  Except as disclosed in the Purchase Agreement, no broker, investment banker, financial advisor or other person is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated hereby based upon arrangements made by or on behalf of the Stockholder.

6.     Purchase Agreement and Related Filings.  The Stockholder hereby covenants and agrees to use reasonable efforts to cooperate with Buyers and Sellers to consummate the Acquisition upon the terms, and subject to the conditions, set forth in the Purchase Agreement (as the same may be amended from time to time).

7.     No Solicitation.  From the date hereof until the termination hereof, the Stockholder will not, directly or indirectly, (i) take any action to solicit, initiate or encourage any acquisition by another entity (the “Acquisition Proposal”) or (ii) engage in negotiations or discussions with, or disclose any nonpublic information relating to Citadel or any subsidiary of Citadel to, or otherwise assist, facilitate or encourage, any person (other than the Buyers) that may be considering making, or has made, a Acquisition Proposal.  The Stockholder will promptly notify McAfee after receipt of any Acquisition Proposal or any indication that any such third party is considering making an Acquisition Proposal or any request for nonpublic information relating to Citadel or any subsidiary of Citadel or for access to the properties, books or records of Citadel or any such subsidiary by any such third party that may be considering making, or has made, a Acquisition Proposal and will keep McAfee fully informed of the status and details of any such Acquisition Proposal, indication or request.  The foregoing provisions of this Section 7 will not be construed to limit actions taken, or to require actions to be taken, by the Stockholder that are required or restricted by fiduciary duties or employment duties of the Stockholder, or permitted by the Purchase Agreement (as the same may be amended from time to time), and that, in each case, are undertaken solely in the Stockholder’s capacity as a director or officer of Citadel, if applicable.

8.     No Solicitation of Proxies.  The Stockholder agrees (solely in his capacity as such) that he will not directly or indirectly, engage in any solicitation (as defined in Regulation 14A of the

9.     Further Assurances.  From time to time, at McAfee’s request and without further consideration, the Stockholder shall execute and deliver such additional documents and take all such further action as may be necessary or appropriate to consummate the transactions contemplated by this Agreement.

10.   Legending of Shares.  If so requested by McAfee, the Stockholder hereby agrees that the Shares shall bear a legend stating that they are subject to this Agreement and to an irrevocable proxy.  Subject to the terms of Section 2 hereof, the Stockholder hereby agrees that the Stockholder shall not Transfer the Shares without first having the aforementioned legend affixed to the certificates representing the Shares.

11.   Termination.  This Agreement shall terminate and shall have no further force or effect as of the Expiration Date.

12.   Miscellaneous.

(a)   Waiver.  No waiver by any party hereto of any condition or any breach of any term or provision set forth in this Agreement shall be effective unless in writing and signed by each party hereto.  The waiver of a condition or any breach of any term or provision of this Agreement shall not operate as or be construed to be a waiver of any other previous or subsequent breach of any term or provision of this Agreement.

(b)   Severability.  In the event that any term, provision, covenant or restriction set forth in this Agreement, or the application of any such term, provision, covenant or restriction  to any person, entity or set of circumstances, shall be determined by a court of competent jurisdiction to be invalid, unlawful, void or unenforceable to any extent, the remainder of the terms, provisions, covenants and restrictions set forth in this Agreement, and the application of such terms, provisions, covenants and restrictions to persons, entities or circumstances other than those as to which it is determined to be invalid, unlawful, void or unenforceable, shall remain in full force and effect, shall not be impaired, invalidated or otherwise affected and shall continue to be valid and enforceable to the fullest extent permitted by applicable law.

(c)   Binding Effect; Assignment.  This Agreement and all of the terms and provisions hereof shall be binding upon, and inure to the benefit of, the parties hereto and their respective successors and permitted assigns, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of the Stockholder may be assigned to any other Person without the prior written consent of McAfee.

(d)   Amendments.  This Agreement may not be modified, amended, altered or supplemented, except upon the execution and delivery of a written agreement executed by each of the parties hereto.

(f)    Governing Law.  This Agreement shall be governed by and construed, interpreted and enforced in accordance with the internal laws of the State of Delaware without giving effect to any choice or conflict of law provision, rule or principle (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.
