Exhibit 99.1

Enterprise Acquisition Corp.

Files Supplement to Proxy Statement

BOCA RATON, Florida, November 2, 2009 – Enterprise Acquisition Corp. (NYSE Amex, Units: “EST.U”, Common Stock: “EST,” Warrants: “EST.WS”) (“Enterprise”) announced today that it has filed a supplement to its definitive proxy materials (the "Supplement") relating to the previously announced proposed business combination with ARMOUR Residential REIT, Inc. ("ARMOUR").  The Supplement is available through the Securities and Exchange Commission's website at www.sec.gov.  Stockholders and warrantholders are urged to read this supplement carefully as it includes important information with respect to the proposed business combination.  

As detailed in the Supplement, the Merger Agreement among Enterprise, ARMOUR and ARMOUR Merger Sub Corp., a Delaware corporation and a wholly-owned subsidiary of ARMOUR, has been amended to delete, as a condition to the closing of the merger, the requirement that Enterprise have at least $100 million in its trust account at the effective time of closing, after taking into account payment of certain expenses.  Enterprise also announced that it had entered into additional forward contracts with institutional investors, bringing the aggregate number of shares subject to such forward contracts, and that will vote in favor of the merger at the special meetings, to approximately 5.2 million.  Despite having removed such minimum cash requirement and entered into such forward contracts, as of November 2, 2009, Enterprise would need approximately 4.5 million additional votes in favor of the merger to consummate the merger.  Enterprise continues to seek additional votes in favor of the proposals set forth below.

The special meetings will be held on Thursday, November 5, 2009 at 9:00 a.m. Eastern time at the offices of Akerman Senterfitt, One Southeast 3rd Avenue, Suite 2500, Miami, Florida 33131.

At the special meeting of stockholders, Enterprise stockholders will be asked to approve (i) amendments to the terms of its amended and restated certificate of incorporation to allow for the consummation of the proposed transaction with ARMOUR; (ii) the merger agreement with ARMOUR and the business combination contemplated by such merger agreement; and (iii) an increase from 30% to 50% the threshold contained in Enterprise's amended and restated certificate of incorporation regarding the amount of shares of common stock issued in Enterprise's initial public offering that may seek conversion without preventing a business combination from being consummated. In addition, at the special meeting of warrantholders, Enterprise warrantholders will be asked to approve an amendment to the warrant agreement to (i) increase the exercise price of Enterprise’s warrants from $7.50 per share to $11.00 per share and (ii) extend the expiration date of the warrants from November 7, 2011 to November 7, 2013.
