All or part of the shares of Common Stock owned by members of the Group may from time to time be pledged with one or more banking institutions or brokerage firms as collateral for loans made by such entities to members of the Group.

| Item 4. | Purpose of Transaction |
| | We hope to work with management and the board to maximize shareholder value over the medium to long term.
Our purpose in acquiring shares of Common Stock of the Issuer is to profit from the appreciation in the market price of the shares of Common Stock through asserting shareholder rights. We do not believe the value of the Issuer's assets is adequately reflected in the current market price of the Issuer's Common Stock.
Members of the Group may seek to make additional purchases or sales of shares of Common Stock. Except as described in this filing, no member of the Group has any plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of Item 4 of Schedule 13D. Members of the Group may, at any time and from time to time, review or reconsider their positions and formulate plans or proposals with respect thereto.
Since 2000, members or affiliates of the Group have taken an 'activist position' in 80 other publicly-traded companies. In each instance, our purpose has been to profit from the appreciation in the market price of the shares we held by asserting shareholder rights. In addition, we believed that the values of the companies' assets were not adequately reflected in the market prices of their shares.
Our actions with respect to such publicly-traded companies are described in Schedule A, attached hereto and incorporated herein by reference. |
