Neither the present filing nor anything contained herein shall be construed as an admission that the Reporting Persons constitute a "group" for any purpose and the Reporting Persons expressly disclaim membership in a group. Item 4.	Purpose of Transaction 	Item 4 is hereby amended to add the following: 	The Reporting Persons have been approached by an advisor to a well- capitalized North American-headquartered semiconductor designer regarding their interest in acquiring the Issuer for a potentially very substantial premium. The Reporting Persons understand that the Issuer's Board of Directors has been made aware of the potential acquirer's interest in acquiring the Issuer and the potential premium the acquirer would potentially pay to acquire the Issuer but believe that no formal indication of interest has been communicated to the Issuer. The Reporting Persons are making this disclosure to avoid trading restrictions while possibly in possession of material, non-public information. 	The Reporting Persons urge the Issuer's board of directors to give prompt, serious consideration to this and any other expressions of interest in acquiring control of the Issuer. -------------------------------------------------------------------------------- Cusip No. 928497304		Schedule 13-D			Page 9 of 9 				SIGNATURES After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
