ITEM 1.01 – ENTRY INTO MATERIAL DEFINITIVE AGREEMENT

On October 15, 2009, Enterprise Acquisition Corp. (the "Company" or "Enterprise") entered into a Stock Purchase Agreement with Fir Tree SPAC Holdings I, LLC ("Fir Tree"), pursuant to which Fir Tree will sell to Enterprise a total of 1,563,000 shares of the Company’s common stock issued in its initial public offering (“Public Shares”) at a price per share of $9.98, subject to adjustment. The purchases will take place concurrently with or following the closing of the merger with ARMOUR Residential REIT, Inc. ("ARMOUR") and the purchases will be paid for with funds that will be released from the Company’s trust account upon consummation of the merger.

Pursuant to the Stock Purchase Agreement, Fir Tree has agreed to have its Public Shares voted in favor of each of the stockholder proposals set forth in the Company's definitive proxy statement/prospectus, dated October 13, 2009, filed with the Securities and Exchange Commission on October 14, 2009.

Such purchases, if made, would increase the likelihood that holders of a majority of the shares of the Company’s common stock will vote in favor of the merger and that holders of less than 30% of Public Shares (or 50% of the Public Shares, if the proposal to increase the conversion threshold is approved at the special meeting) vote against the merger and seek conversion of their Public Shares into cash in accordance with the Company’s amended and restated certificate of incorporation.

The foregoing description of the Stock Purchase Agreement is qualified in its entirety by the copy of such agreement filed as Exhibit 10.1 to this report, which is incorporated herein by this reference.

This communication is being made in respect of the proposed business combination involving Enterprise and ARMOUR. In connection with the proposed transaction, ARMOUR filed Amendment No. 4 to the Registration Statement on Form S-4 with the SEC on October 13, 2009, and the definitive Proxy Statement/Prospectus for Enterprise was mailed to stockholders and warrantholders of Enterprise on October 14, 2009. INVESTORS AND SECURITY HOLDERS OF ENTERPRISE ARE URGED TO READ THE DEFINITIVE PROXY STATEMENT/PROSPECTUS AND OTHER DOCUMENTS FILED WITH THE SEC CAREFULLY IN THEIR ENTIRETY BECAUSE THEY CONTAIN IMPORTANT INFORMATION ABOUT THE PROPOSED TRANSACTION. Investors and security holders will be able to obtain free copies of the definitive Proxy Statement/Prospectus and other documents filed with the SEC by Enterprise and ARMOUR through the website maintained by the SEC at www.sec.gov.
