Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

As a result of the Merger (as defined in Item 5.01 below) and related transactions, hi/fn, inc. (“Hifn”) no longer fulfills the numerical listing requirements of The NASDAQ Global Market. Accordingly, Hifn requested that its common stock, par value $0.001 per share (the “Common Stock”), be withdrawn from listing on The NASDAQ Global Market as of the close of business on April 3, 2009. The NASDAQ Stock Market, LLC (“NASDAQ”) has filed with the Securities and Exchange Commission (“SEC”) a Form 25 Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to delist and deregister the Common Stock. Upon the filing, the Common Stock was delisted from The NASDAQ Global Market. Hifn also intends to file with the SEC a Certification and Notice on Form 15 under the Exchange Act, requesting that the Common Stock be deregistered and that Hifn’s reporting obligations under Sections 13 and 15(d) of the Exchange Act be suspended.

Item 5.01. Changes in Control of Registrant.

On February 23, 2009, Hifn entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Exar Corporation (“Exar”) and Hybrid Acquisition Corp., a wholly-owned subsidiary of Exar (“Acquisition Sub”). Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, Acquisition Sub commenced an offer for all of the outstanding shares of Common Stock at a purchase price of either (i) $4.00 per share, net to the seller in cash, without interest and less any applicable withholding taxes or (ii) 0.3529 shares of Exar common stock and $1.60 per share, net to the seller in cash, without interest and less any applicable withholding taxes (the “Offer”).

The Offer expired at 12:00 midnight, New York City time, at the end of April 2, 2009. The exchange agent reported a final count of 13,886,277 shares of Common Stock (including 345,555 shares of Common Stock guaranteed to be delivered within the next three days), representing approximately 91.3 percent (or 93.6 percent, including shares of Common Stock guaranteed to be delivered within the next three days) of the total outstanding shares of Common Stock, tendered and not withdrawn in the Offer. Exar accepted for payment all tendered shares on April 3, 2009.

On April 3, 2009, Exar completed the acquisition of Hifn through the merger of Acquisition Sub with and into Hifn (the “Merger”) in accordance with applicable provisions of Delaware law that authorize the completion of the Merger without a vote of Hifn stockholders. In the Merger, all remaining shares of Common Stock not tendered in the Offer (other than shares held in Hifn’s treasury or owned by Hifn, Exar, or their respective subsidiaries, and other than shares for which appraisal rights are properly exercised) were converted into the right to receive 0.3529 shares of Exar common stock and $1.60 per share, net to the stockholder in cash, without interest and less any applicable withholding taxes.

Exar is expected to issue approximately 385,832 shares of Exar common stock and to pay approximately $56,709,766 in cash to fund the acquisition of shares tendered in the Offer and the payment of the merger consideration in the Merger.

Pursuant to the terms of the Merger Agreement, Albert E. Sisto, Chairman and Chief Executive Officer of Hifn, became a director of Exar on April 3, 2009.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

Pursuant to the terms of the Merger Agreement, the principal executive officer, principal financial officer, all executive officers and all directors of Hifn resigned as of the consummation of the Merger.
