Item 3. Source and Amount of Funds or Other Consideration. Item 3 is hereby amended to add the following as the second paragraph thereof: Any funds necessary for the proposed transaction described in Item 4 below will be paid out of the Reporting Person's working capital. Item 4. Purpose of Transaction The third, fourth and fifth paragraphs of Item 4 are hereby amended and restated in their entirety as follows: On August 21, 2001, the Reporting Person issued a press release stating that the Reporting Person plans to make a cash tender offer by the end of September 2001 for any and all of the outstanding Shares of the Issuer held by minority stockholders at $20 per Share in cash.

If the Reporting Person achieves this 90% ownership threshold, it will acquire all remaining outstanding Shares through a subsequent short-form merger in Delaware, the timing of which will be announced at a later date. It is the current intention of the Reporting Person that stockholders who do not tender their Shares to the Reporting Person during the tender offer would also receive $20 per Share in cash for their Shares in the short-form merger.

Except as set forth in this Item 4, neither the Reporting Person nor, to the Reporting Person's knowledge, any of the executive officers or directors of the Reporting Person has any current plans or proposals which relate to or would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D, although the Reporting Person and such other persons do not rule out the possibility of effecting or seeking to effect any such actions in the future.
