On July 11, 2005, Helix Technology Corporation, a Delaware corporation (“Helix”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Brooks Automation, Inc., a Delaware corporation (“Brooks”), and Mt. Hood Corporation, a Delaware corporation and wholly owned subsidiary of Brooks. Under the terms of the Merger Agreement, which was unanimously approved by the boards of directors of both Helix and Brooks, Helix stockholders will receive 1.11 shares of Brooks common stock for each share of Helix common stock. Based on the closing price of Brooks common stock on July 8, 2005, the transaction values Helix at $454 million. Brooks stockholders will own 61% and Helix stockholders will own 39% of the combined company on a fully diluted basis. The transaction is expected to be tax-free to the stockholders of both companies for U.S. federal income tax purposes. Completion of the transaction is subject to the applicable Hart-Scott-Rodino waiting period, stockholder approval of each company and other customary closing conditions. The transaction is expected to occur in the fourth calendar quarter of 2005.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, attached hereto as Exhibit 2.1 and incorporated herein by reference. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed by the contracting parties, including being qualified by disclosures exchanged between the parties in connection with the execution of the Merger Agreement. The representations and warranties may have been made for the purposes of allocating contractual risk between the parties to the agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors are not third-party beneficiaries under the Merger Agreement and should not view the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Brooks or Helix or any of their respective subsidiaries.
