þ
	(a)	The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense

	(b)	The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and

	(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Trident Microsystems, Inc. (the “Company”), is unable to file its annual report on Form 10-K for the fiscal year ended June 30, 2007 (the “Fiscal 2007 10-K”), by the prescribed filing date of August 29, 2007, without unreasonable expense or effort, as a result of the following. As previously disclosed in its Annual Report on Form 10-K for the fiscal year ended June 30, 2006 (“Fiscal 2006 10-K”), and in its Quarterly Reports on Form 10-Q for the quarters ended September 30, 2006, December 31, 2006 and March 31, 2007 (collectively the “Fiscal 2007 Form 10-Qs”), the Company has been engaged in an investigation into its historical stock option grant practices and related issues. As a result of the findings from this investigation, which was completed in July 2007, the Company restated certain previously filed annual and quarterly financial statements to record additional stock-based compensation expense, as disclosed in its Fiscal 2006 10-K. The Company filed its Fiscal 2006 10-K on August 7, 2007, and its Fiscal 2007 Form 10-Qs on August 21, 2007.

Since that date, the Company has been diligently working to complete its Fiscal 2007 10-K. However, due to the amount of effort required to complete and file the Fiscal 2006 10-K and the Fiscal 2007 Form 10-Qs, the Company has been unable to complete the Fiscal 2007 10-K in time to file by August 29, 2007.

The Company expects that it will be able to file its Fiscal 2007 10-K on or before the fifteenth calendar day following the required filing date as prescribed in Rule 12b-25, and therefore expects to remain current in its filing obligations.
