Helix Prices Secondary Public Equity Offering of
Cal Dive Common Stock

HOUSTON, TX — (September 18, 2009) Cal Dive International, Inc. (NYSE:DVR) announced today that the previously disclosed secondary offering of 20,604,317 shares of Cal Dive common stock by Helix Energy Solutions Group, Inc. (NYSE:HLX) (“Helix”) was priced at $10.00 per share.

The offering is expected to close on September 23, 2009, subject to customary closing conditions. In addition, Helix has granted the underwriters an option to purchase an additional 3,090,647 shares to cover over-allotments, if any.

Assuming the exercise of the over-allotment option in full, Helix will cease to own any shares of Cal Dive’s common stock. Helix will receive all net proceeds from the secondary offering.

In connection with the offering, Credit Suisse Securities (USA) LLC and BofA Merrill Lynch are acting as joint book-running managers and Capital One Southcoast, Inc. is acting as co-manager for the offering.
