Connection With its Tender Offers and Consent Solicitations

Hanover Compressor Company (the “Company”) today announced that, in connection with its previously announced tender offers and consent solicitations for $550 million of its outstanding senior notes (as described in the table below and, collectively, the “Notes”), it has received the requisite consents to amend the indentures governing the Notes. As of 5:00 p.m., New York City time, on August 1, 2007 (the “Consent Payment Deadline”), the Company had received tenders and consents as displayed in the table below.

     The supplemental indentures effecting the proposed amendments have been executed and have become effective, and the amendments to the indentures will become operative upon the acceptance for purchase of the Notes by the Company. The amendments to the indentures eliminate substantially all of the restrictive covenants and eliminate or modify certain events of default in the indentures governing the Notes, as described in the Offer to Purchase and Consent Solicitation Statement dated as of July 19, 2007 (“the Offer to Purchase”). Withdrawal rights with respect to tendered Notes have expired. Accordingly, Notes tendered may no longer be withdrawn and consents delivered may no longer be revoked.

     Each holder who validly tenders its Notes and delivers consents at or after the Consent Payment Deadline will not be entitled to receive the consent payment of $30 for each $1,000 principal amount of Notes tendered by such holder and accepted for purchase pursuant to a tender offer.
