Enterprise Acquisition Corp. Announces October 29, 2009 Special Meeting of

Stockholders and Warrantholders to Approve Merger

with ARMOUR Residential REIT, Inc.

BOCA RATON, Florida, October 23, 2009 – Enterprise Acquisition Corp. (NYSE Amex, Units: “EST.U”, Common Stock: “EST,” Warrants: “EST.WS”) (“Enterprise”) announced today that it has postponed the special meetings of its stockholders and warrantholders, which had previously been scheduled for Monday, October 26, 2009, at 9:00 a.m. Eastern time, to Thursday, October 29, 2009, at 9:00 a.m. Eastern time. Enterprise believes that postponing the special meetings will allow Enterprise's stockholders and warrantholders, as well as certain potential investors, additional time to consider and evaluate the proposals set forth below, and would result in a higher equity base for the combined company.

The postponed special meetings will be held on Thursday, October 29, 2009 at 9:00 a.m. Eastern time at the offices of Akerman Senterfitt, One Southeast 3rd Avenue, Suite 2500, Miami, Florida 33131. The record date for the postponed special meetings remains October 5, 2009.

At the postponed 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 Residential REIT, Inc. ("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, 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.
