Summary of INTEGRATED DEVICE TECHNOLOGY INC

Item 8.01 Other Events.

On November 9, 2012, Integrated Device Technology, Inc. ("IDT") announced that it is extending the expiration date of its exchange offer for all outstanding shares of common stock of PLX Technology, Inc. ("PLX"), pursuant to the previously announced merger agreement with PLX, dated April 30, 2012, which contemplates the exchange offer for all outstanding shares of PLX common stock, followed by a second step merger. The exchange offer was previously scheduled to expire at the end of the day on November 9, 2012, at 12:00 midnight, New York City time. The exchange offer is being extended as the applicable waiting period pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of 1976 ("HSR Act") has not yet expired or been terminated, and the exchange offer is now set to expire at the end of the day on December 10, 2012, at 12:00 midnight, New York City time, unless further extended. Approximately 19.4 million shares, or approximately 43.1% of PLX's outstanding common stock, had been tendered as of 12:00 midnight at the end of the day on November 8, 2012. The full text of the press release is attached as Exhibit 99.1 to this current report on Form 8-K.

Correspondingly, in order for the trustee of the PLX Employee Stock Ownership Plan ("ESOP") to be instructed in a timely manner to tender or not tender all or a portion of the shares allocated to such participant's account under the ESOP, each participant in the ESOP must complete and return the ESOP instruction form previously provided to participants so that it is received by Computershare, the tabulation agent for the offer, not later than 5:00 p.m., New York City time, on December 5, 2012, unless the offer is further extended.

As previously disclosed, on May 7, 2012, in connection with the merger agreement, IDT and PLX made premerger filings under the HSR Act with the Federal Trade Commission ("FTC") and the Antitrust Division of the U.S. Department of Justice. Effective June 5, 2012, following consultation with the FTC and PLX, IDT voluntarily withdrew its Notification and Report Form with respect to the exchange offer and the merger. IDT re-filed its Notification and Report form on June 6, 2012. On July 6, 2012, IDT and PLX each received a request for additional information from the FTC (the "Second Request"). This Second Request extends the waiting period applicable to the exchange offer under the HSR Act, which was set to expire on July 6, 2012 at 11:59 p.m., New York City time. The waiting period is extended until 11:59 p.m., New York City time, on the thirtieth day (or the next business day) after both IDT and PLX substantially comply with the Second Request, as specified by the HSR Act and the implementing rules, unless further extended by agreement with the parties.
