This Amendment No. 5 is being made primarily to update the Reporting Person’s disclosures under Items 4, 6 and 7.

All of the Common Stock beneficially owned by the Reporting Person was acquired by the Reporting Person and affiliated entities of the Reporting Person either:

Each of the Reporting Person and affiliated entities of the Reporting Person acquired the shares of Common Stock of the Issuer for investment purposes only and not with the intent of acquiring control of the Issuer.

On January 22, 2013, the Issuer entered into an agreement (the “Agreement”) with the Reporting Person, The Argyros Family Foundation, The Argyros Family Trust, GLA Financial Corporation, HBI Financial, Inc., The Lenore Trigonis Trust Established under the Leon and Olga Argyros 1986 Trust and The Selia Poulos Trust Established under the Leon and Olga Argyros 1986 Trust (collectively, the “Argyros Group”).

The Agreement provides that (1) the Issuer’s board of directors (the “Issuer Board”) shall remain fixed at no more than nine directors at least until the conclusion of the 2014 Annual Meeting; (2) the Issuer will continue to take all necessary actions to nominate Stephen C.

The Agreement also provides that, so long as the Issuer complies with its Agreement obligations, the Argyros Group and its members will not (1) nominate any person for election at the 2013 Annual Meeting; or (2) submit any proposal for consideration at, or bring any other business before, the 2013 Annual Meeting. Additionally, so long as the Issuer complies with its Agreement obligations, at the 2013 Annual Meeting each member of the Argyros Group shall cause (a) all shares of the Issuer’s common stock that it beneficially owns to be present for quorum purposes and (b) all the votes associated with one-third of the shares of the Issuer’s common stock that it beneficially owns to be voted in favor of each Nominee, subject to certain rights of the Argyros Group to cumulate votes (in its sole discretion) on certain Nominees (1) upon the receipt of notification from the Issuer that it is in the best interest of the Issuer to cumulate votes on certain Nominees or (2) in the event that a third party other than the Argyros Group submits a dissident slate of one or more candidate(s).

The foregoing description of the Agreement is qualified in its entirety by reference to the full text of the Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

Other than as described in the preceding paragraphs, the Reporting Person has no present plans or proposals that relate to or would result in any of the matters referred to in subparagraphs (a) through (j) of Item 4 of Schedule 13D. However, as part of his ongoing review of investment alternatives, the Reporting Person may consider such matters in the future and, subject to applicable law, may formulate a plan with respect to such matters, or may engage in communications with management or the Issuer Board, other stockholders of the Issuer or other parties regarding such matters, including but not limited to operations, strategy, management, capital structure and the strategic alternatives that may be available to the Issuer.

(a) The Reporting Person beneficially owns 9,683,604 shares of Common Stock of the Issuer, which represent approximately 21.38% of the outstanding shares of Common Stock of the Issuer (based on the 45,297,344 shares of Common Stock outstanding on October 31, 2012, as reported in the Issuer’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2012).
