Hornbeck Offshore is offering to purchase the Notes using fixed-spread pricing that will result in total consideration for each $1,000 principal amount of Notes validly tendered equal to the present value on the applicable settlement date of the optional redemption price of $1,053.13 at the first call date for the Notes, August 1, 2005, plus the interest that would accrue from the last interest payment date on the Notes to the first call date, as determined by reference to a fixed spread of 0.75% over the yield to maturity of the 1.50% U.S. Treasury Security due July 31, 2005, minus accrued interest on the Notes from the last interest payment date to the applicable settlement date. Holders who tender their Notes prior to 5:00 p.m., Eastern time, on November 17, 2004 (the “Consent Time”) will be eligible to receive the total consideration, which includes a consent payment equal to $30 per $1,000 of principal. Holders who tender their Notes after the Consent Time but prior to 5:00 p.m., Eastern time, on December 3, 2004 (the “Expiration Time”) will not be eligible to receive the $30 consent payment. In addition, Hornbeck Offshore will pay accrued interest up to, but not including, the applicable settlement date on all Notes accepted in the Offer. Subject to the conditions of the Offer, the initial settlement date with respect to all Notes tendered prior to the Consent Time will be within five business days of the Consent Time, which is expected to be November 24, 2004.

The purchase price for the Notes will be determined by the Dealer Manager and publicly announced by 5:00 p.m., Eastern time, on November 16, 2004.

Holders that tender their Notes prior to the Consent Time will be eligible to receive the total consideration on the initial settlement date, and holders that tender their Notes after the Consent Time but prior to the Expiration Time will be eligible to receive the total consideration less the consent payment on the final settlement date.
