Following the Merger of the Purchaser with and into Third Wave as disclosed under item 2.01. below, Third Wave and its domestic subsidiary Third Wave Agbio, Inc. joined as (i) guarantors under Hologic's amended and restated credit agreement relating to a senior secured credit facility (the "Amended Credit Agreement") with Goldman Sachs Credit Partners L.P., as Sole Lead Arranger and Sole Lead Bookrunner, Goldman Sachs Credit Partners L.P., JPMorgan Chase Bank, N.A. and RBS Citizens, National Association, as Co-Syndication Agents, Goldman Sachs Credit Partners L.P. as Administrative Agent and Collateral Agent and Royal Bank of Canada, as Documentation Agent and each lender from time to time party thereto and (ii) grantors under Hologic's amended and restated pledge and security agreement by and among Goldman Sachs Credit Partners L.P., as collateral agent, Hologic and the other parties therein named ("Amended Pledge Agreement").

A description of the terms of the Amended Credit Agreement and Amended Pledge Agreement is set forth in item 1.01. of the Current Report on Form 8-K filed by Hologic on July 17, 2008 and each of the Amended Credit Agreement and Amended Pledge Agreement is filed as exhibit 10.1 and 10.2 to such report. The description and the exhibits are incorporated herein by reference.

On July 24, 2008, pursuant to the terms of the Merger Agreement, Hologic completed the acquisition of Third Wave through the merger (the "Merger") of the Purchaser with and into Third Wave. The Merger was consummated without a meeting of the stockholders of Third Wave in accordance with the Delaware General Corporation Law. As a result of the Merger, all remaining outstanding Shares were converted into the right to receive $11.25 per Share in cash, without interest, other than Shares held by Hologic or the Purchaser or Shares held by Third Wave stockholders that perfect their rights to appraisal in accordance with the Delaware General Corporation Law.

The total cost of all of Third Wave's outstanding equity interest (common stock as well as options and warrants) is approximately $600 million.

The foregoing description of the Merger does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which was previously filed with Securities and Exchange Commission ("SEC") by Hologic on Form 8-K on June 9, 2008 and is incorporated herein by reference as Exhibit 2.1.
