Item 4.

PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended and supplemented to include the following:

The Reporting Person intends to review its investment on a regular basis and, as a result thereof, may, directly or through one or more affiliates, at any time or from time to time determine, either alone or as part of a group, (i) to acquire additional securities of the Issuer, through open market purchases, privately negotiated transactions, or otherwise, (ii) to dispose of all or a portion of the securities of the Issuer in the open market, in privately negotiated transactions, or otherwise, or (iii) to take any other available course of action, which could involve one or more of the types of transactions or have one or more of the results specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Securities and Exchange Act of 1934, as amended. Any such acquisition or disposition or other transaction would be made in compliance with all applicable laws and regulations.

The Reporting Person may explore and evaluate, various potential alternatives with respect to his investment in the Issuer, including, among other things, extraordinary corporate transactions involving the Issuer. There can be no guarantee that the Reporting Person will make any such proposal, and if any such proposal is made, the Reporting Person can provide no assurances such proposal will be accepted or that it will successfully consummate any proposed transaction. Continued exploration of any such proposal, and whether the Reporting Person will make any such proposal and the completion of any such proposed transaction, is subject to many factors, many of which are outside the control of the Reporting Person, including, but not limited to, the following: terms believed by the Reporting Person to be favorable to him; the Reporting Person’s ongoing assessment of the Issuer’s business, prospects, and other developments concerning the Issuer and its businesses generally; changes in law and government regulations; general economic conditions; tax considerations; other investment opportunities available to the Reporting Person; and prevailing market conditions, including the market price of the securities of Issuer.

The Reporting Person may engage in communications, discussions and negotiations with members of management and of the board of directors of the Issuer, and its legal, financial, accounting and other advisors; potential partners and counterparties in any transaction; current or prospective stockholders of the Issuer; and other relevant parties, regarding the various alternatives that may from time to time be under consideration by the Reporting Person and/or its affiliates. To facilitate its consideration of such matters, the Reporting Person has retained, or intends to retain, consultants and advisors and enter into discussions with potential sources of capital and other third parties. The Reporting Person may exchange information with any such persons pursuant to appropriate confidentiality or similar obligations or agreements.

Except as set forth in this Item 4, the Reporting Person currently has no present plan or proposal that relates to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Exchange Act.
