(Commission File No.:0-22623)

This filing relates to a proposed acquisition (the “Acquisition”) by The Cooper Companies, Inc. (“Cooper”) of Ocular Sciences, Inc. (“Ocular Sciences”) pursuant to the terms of an Agreement and Plan of Merger, dated as of July 28, 2004 (the “Merger Agreement”), by and among Cooper, TCC Acquisition Corp., a wholly owned subsidiary of Cooper, and Ocular Sciences. The Merger Agreement is on file with the Securities and Exchange Commission (“SEC”) as an exhibit to the Current Report on Form 8-K filed by Cooper on July 29, 2004, and is incorporated by reference into this filing.

The following is a letter dated July 28, 2004 sent from A. Thomas Bender, Chairman and Chief Executive Officer of Cooper to all Cooper employees via email in connection with Cooper’s proposed acquisition of Ocular Sciences.

Dear Cooper Company Employee:

I’m pleased to announce that today, The Cooper Companies, Inc. entered into a definitive agreement to purchase Ocular Sciences.

As many of you know, Ocular Sciences is one of the world’s leading contact lens manufacturers and we are excited to be joining forces with them. We expect to close the transaction in the first quarter of our 2005 fiscal year, which begins on November 1, 2004.

Each company brings a strong portfolio to the combination and views the other as a strong partner. The businesses are highly complementary in their geographic markets, their product lines, their customers and their research programs. The combined company will be the world’s third largest contact lens manufacturer.

The terms of the transaction provide that Ocular Sciences shareholders will receive $22.00 in cash and .3879 of a share of Cooper common stock for each of their Ocular Sciences shares so, if they choose, Ocular shareholders can continue to participate in the results of the new company going forward.

I will remain the chairman of the board and chief executive officer of the Cooper and Bob Weiss will remain the executive vice president and chief financial officer. Greg Fryling will remain as chief operating officer of CooperVision. John Fruth, the founder and chairman of the board and chief executive officer of Ocular Sciences, will be asked to join the Cooper board.

The companies will continue for the present to manufacture their existing products and their current locations. We expect that it will take a minimum of three years to totally integrate our two organizations and their subsidiaries around the world.

This acquisition is a major milestone in Cooper’s history. Just ten years ago CooperVision revenue was less than $50 million. When CooperVision and Ocular Sciences are combined, our expected annual sales for calendar 2005 will be nearly $1 billion. I attribute this outstanding performance to the dedication and commitment of our employees, and I thank you for your support.

Sincerely,

Tom

A. Thomas Bender

Chairman and Chief Executive Officer

The Cooper Companies, Inc.
