Trident Microsystems Chief Executive Officer Adopts 10b5-1 Plan

SUNNYVALE, Calif., Nov 15 /PRNewswire-FirstCall/ -- Trident Microsystems, Inc. (NASDAQ:TRID) a leading provider of digital TV technology for the consumer digital video marketplace today announced that Frank C. Lin, president, Chief Executive Officer and chairman of the Board of Directors, has established a pre-arranged trading plan to sell shares of the company over a designated period in accordance with rule 10b5-1 of the Securities and Exchange Commission. Under the plan, during a twelve month period commencing on December 12, 2005, Mr. Lin plans to sell up to 1,250,000 pre split shares of Trident Microsystems common stock in open market transactions in limited quantities over given periods of time, that may increase if the price of the stock increases. Some of the shares to be sold under the plan were acquired in previous open market purchases or as a result of exercises of option grants, and some will be acquired through the exercise of employee stock options. Transactions under this plan will be disclosed publicly through Form 144 and Form 4 filings with the Securities and Exchange Commission. The transactions are part of Mr. Lin's ongoing program of tax planning and asset diversification; if all shares are sold under the plan, Mr. Lin's ownership of Trident Microsystems common stock will decrease from approximately 7% currently to between approximately 2.5% and 3%.

Rule 10b5-1 permits insiders to implement a written plan to sell stock when they are not in possession of material non-public information and continue to sell shares on a regular basis even if they receive such information subsequently. Such plans establish predetermined trading parameters that do not permit the person adopting the plan to exercise any subsequent influence over how, when, or whether to effect trades. Using these plans, insiders can gradually diversify their investment portfolios, spread stock trades out over an extended period of time to reduce market impact, and avoid concerns about transactions occurring at a time when they might possess inside information.
