Item 4. Purpose of the Transaction.

The purpose of this Schedule 13D is to report that Ms. Singer entered into a Voting and Standstill Agreement (the “Standstill Agreement”) with the Issuer on November 18, 2008. Pursuant to the Standstill Agreement, on or before December 10, 2008, the Issuer will increase the size of its Board of Directors (the “Board”) from five to eight members and appoint one designee of Ms. Singer and certain other stockholders who, acting separately, entered into similar agreements (the “Stockholders”) to the class of directors whose term shall expire at the Issuer’s 2009 Annual Meeting of Stockholders (the “2009 Stockholder Designee”) and one designee of the Stockholders to the class of directors whose term shall expire at the issuer’s 2010 Annual Meeting of Stockholders (the “2010 Stockholder Designee”). In addition, at the issuer’s 2009 Annual Meeting of Stockholders, the issuer has agreed to nominate the 2009 Stockholder Designee to the class of directors whose term shall expire at the issuer’s 2012 Annual Meeting of Stockholders and the 2010 Stockholder Designee to the class of directors whose term shall expire at the issuer’s 2010 Annual Meeting of Stockholders and to use its reasonable best efforts to elect each of these designees to the Board. The issuer has also agreed, upon the earlier to occur of January 1, 2009 or the closing of the Asset Sale, to appoint Joel Hughes as Chief Executive Officer of the Issuer and to the class of directors whose term shall expire at the issuer’s 2011 Annual Meeting of Stockholders.

Pursuant to the terms of the Standstill Agreement, the Issuer accepted the resignations of Robert P. Schechter and Ronald White, each effective as of January 1, 2009. As soon as practicable following the effectiveness of the resignations of Messrs. Schechter and White, the Issuer will reduce the size of its Board from eight to six members. The Issuer shall also use commercially reasonable efforts to appoint to the Board prior to February 28, 2009, in addition to the appointments of the 2009 Stockholder Designee and the 2010 Stockholder Designee, one (1) individual (the “Additional Independent Director”) who is (x) “independent” under applicable securities laws and applicable stock exchange rules and regulations (or, if the Common Stock is not listed on a stock exchange, any rules or regulations of any market on which the Common Stock is listed or traded), (y) not an affiliate of any Stockholder and (z) recommended by the nominating committee of the Board. One member of the Board, in addition to Messrs. Schechter and White, shall resign effective as of the later of January 1, 2009 and the appointment of the Additional Independent Director to the Board.

Ms. Singer also agreed to vote, and irrevocably granted the Issuer her proxy to vote, all of her shares of Common Stock beneficially owned by her and her affiliates in favor of the proposals set forth in the Issuer’s proxy statement dated October 20, 2008.

holds its 2009 Annual Meeting of Stockholders (which date shall be no later than June 29, 2009) (the “Standstill Period”), Ms. Singer and her affiliates, without the written consent of the Issuer, has agreed not to form, join or in any way participate in a “group” (as defined under the Securities Exchange Act of 1934, as amended), solicit written proxies or written consents in any contested election of directors to the Board or seek to advise or influence any person with respect to voting, holding or disposing of Common Stock; take or propose certain actions with respect to asset acquisitions, tender or exchange offers, mergers, business combinations, recapitalizations, restructurings, liquidations, dissolutions or other extraordinary transactions. In addition, Ms. Singer has also agreed, among other things, not to engage in a proxy contest; seek to control or influence the management, the Board, or policies of the Company; and nominate any persons as a director of the Company (except as otherwise provided in the Standstill Agreement) or propose any matter to be voted on by stockholders of the Company.

A copy of the Standstill Agreement is attached hereto as Exhibit 99.1.

Except as described above in this Item 4 and herein, Ms. Singer does not currently have any specific plans or proposals that relate to or would result in any of the actions or events specified in clauses (a) through (j) of Item 4 of Schedule 13D. Ms. Singer reserves the right to take any and all actions permitted by applicable law that she may deem appropriate to maximize the value of her investments in light of her general investment policies, market conditions, subsequent developments affecting the Issuer and the general business and future prospects of the Issuer.
