Hologic, Inc. Accepts Shares of Third Wave Technologies, Inc. in Tender Offer and Commences Subsequent Offering Period

BEDFORD, Mass. and MADISON, Wis., July 17 /PRNewswire-FirstCall/ — Hologic, Inc. (NASDAQ:HOLX) and Third Wave Technologies, Inc. (NASDAQ:TWTI) (“Third Wave”), today jointly announced the expiration of the initial offering period of the tender offer by its wholly-owned subsidiary Thunder Tech Corp. (the “Purchaser”) for all outstanding shares of common stock of Third Wave. The initial offering period expired, as scheduled, at 12:00 midnight, New York City time, on Wednesday, July 16, 2008.

The depositary for the offer has advised Hologic and the Purchaser that, as of the expiration of the initial offering period, a total of approximately 45,225,950 Third Wave shares were validly tendered to the Purchaser (including shares tendered via the guaranteed delivery procedure) and not withdrawn, representing approximately 92.1% of the outstanding common stock of Third Wave. The Purchaser has accepted for payment all Third Wave shares that were validly tendered during the initial offering period.

Hologic also announced that the Purchaser has commenced a subsequent offering period for all remaining shares of Third Wave common stock to permit stockholders who have not yet tendered their shares the opportunity to do so. This subsequent offering period will expire at 12:00 midnight, New York City time, on Wednesday, July 23, 2008, unless further extended. Any such extension will be followed by a public announcement no later than 9:00 a.m., New York City time, on the next business day after the subsequent offering period was scheduled to expire.

The same $11.25 per share price offered in the prior offering period will be paid during the subsequent offering period. All shares validly tendered during this subsequent offering period will be immediately accepted and payment will be made promptly after acceptance, in accordance with the terms of the offer. Procedures for tendering shares during the subsequent offering period are the same as during the initial offering period with two exceptions: (1) shares cannot be delivered by the guaranteed delivery procedure, and (2) pursuant to Rule 14d-7(a)(2) promulgated under the Securities Exchange Act of 1934, as amended, shares tendered during the subsequent offering period may not be withdrawn.

Pursuant to the terms of the previously announced merger agreement, Hologic expects to effect a merger of the Purchaser with and into Third Wave. In the merger, the Purchaser will acquire all other Third Wave shares (other than those as to which holders properly exercise appraisal rights) at the same $11.25 per share price, without interest and less any required withholding taxes, that was paid in the tender offer. As a result of the merger, Third Wave will become a wholly-owned subsidiary of Hologic. Hologic intends to complete the merger as soon as practicable. If, as a result of additional shares tendered and purchased in the subsequent offering period or otherwise, the Purchaser becomes the owner of at least 90% of the outstanding Third Wave shares, the Purchaser will be able to effect the merger without the need for a meeting of Third Wave stockholders. Third Wave stockholders who continue to hold their shares at the time of the merger and fulfill certain other requirements of Delaware law will have appraisal rights in connection with the merger.
