Exhibit 10.2

STOCK PURCHASE AGREEMENT

STOCK PURCHASE AGREEMENT (this “Agreement”) made as of this ___ day of October, 2009 among Enterprise Acquisition Corp., a Delaware corporation (“Buyer” or “Enterprise”), the signatory on the execution page hereof (“Seller”) and solely for the purposes of Sections 4(d), 7 and 8(a) hereof, Marc H. Bell (“Bell”) and Daniel C. Staton (“Staton” and together with Bell, the “Insiders”) and solely for the purposes of Sections 8(a) and 8(b) hereof, ARMOUR Residential REIT, Inc. (“ARMOUR”).

WHEREAS, Buyer was organized for the purpose of acquiring, through a merger, capital stock exchange, asset acquisition or other similar business combination, an operating business (“Business Combination”); and

WHEREAS, Buyer consummated an initial public offering in November 2007 (“IPO”) in connection with which it raised gross proceeds of approximately $250 million, a significant portion of which was placed in a trust account (the “Trust Account”) maintained by Continental Stock Transfer and Trust Company (“Continental”) pending the consummation of a Business Combination, or the dissolution and liquidation of Buyer in the event it is unable to consummate a Business Combination on or prior to November 7, 2009; and

WHEREAS, Buyer has entered into that certain Agreement and Plan of Merger, dated July 29, 2009, among Enterprise, ARMOUR, and ARMOUR Merger Sub Corp., a Delaware corporation (“Merger Sub Corp.”) and a wholly-owned subsidiary of ARMOUR (the “Merger Agreement”), pursuant to which (i) Merger Sub Corp. will merge with and into Enterprise with Enterprise surviving the merger and becoming a wholly-owned subsidiary of ARMOUR and (ii) holders of Enterprise securities at the time of merger will be security holders of ARMOUR (the “Merger”); and

WHEREAS, the approval of the Merger is contingent upon, among other things, the affirmative vote of holders of a majority of the outstanding common shares of Enterprise which are present and entitled to vote at the special meeting called to approve the Merger; and

WHEREAS, pursuant to certain provisions in Buyer’s certificate of incorporation, a holder of shares of Buyer’s common stock issued in the IPO may, if it votes against the Merger, demand that Buyer convert such common shares into cash (“Conversion Rights”); and

WHEREAS, the Merger cannot be consummated if holders of 30% (or 50% in the event the secondary charter proposal is approved at the Enterprise special meeting of stockholders to vote upon the Merger) or more of Enterprise common stock issued in the IPO exercise their Conversion Rights; and

WHEREAS, Seller has agreed to sell to Buyer and Buyer has agreed to purchase from Seller the common shares set forth on the execution page of this Agreement (“Shares”) for the purchase price per share set forth therein (“Purchase Price Per Share”) and for the aggregate purchase price set forth therein (“Aggregate Purchase Price”) plus the fees set forth therein (the “Fees”).

NOW, THEREFORE, for and in consideration of the mutual covenants hereinafter set forth and other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereby agree as follows:

Purchase. Seller hereby agrees to sell to Buyer and Buyer hereby agrees to (i) purchase from Seller at the Closing (as defined in Section 4(c)) the Shares at the Purchase Price Per Share, for the Aggregate Purchase Price and (ii) pay the Fees to Seller at the Closing.

Agreement not to Convert. In further consideration of the Aggregate Purchase Price and the Fees, provided that the representations and warranties made by Buyer in Section 6 hereof are true and correct on the date of the stockholder meeting in connection with the approval of the Merger with the same effect as though made on such date and Buyer has complied in all material respects with its obligations set forth in this Agreement through such date, Seller hereby agrees it has not and will not exercise its Conversion Rights or, if it has already exercised its Conversion Rights, it hereby withdraws and revokes such exercise and will execute all necessary documents and take all actions required in furtherance of such revocation.

No Right to Additional Shares. In connection with the Merger, Enterprise’s stockholders of record are entitled to receive one share of ARMOUR common stock for each share of Enterprise common stock owned immediately prior to the consummation of the Merger (the “Exchange”). Although Seller will be a stockholder of record immediately prior to the Merger, Seller hereby acknowledges that Seller irrevocably waives any right, title or interest it may have in receiving any such ARMOUR common stock distributed pursuant to the Exchange. Seller hereby acknowledges that by virtue of the sale hereunder and receipt of payment by Seller of the Aggregate Purchase Price, Seller will not become a stockholder of ARMOUR. Additionally, each of Buyer and Seller hereby agree and acknowledge that this provision is material to this Agreement and a significant consideration in Buyer’s willingness to enter into this Agreement. Notwithstanding the foregoing, such waiver shall not be effective in the event that Seller does not timely receive the Aggregate Purchase Price and the Fees pursuant to the terms of this Agreement.

Closing Matters.

(a)

Within one business day of the date of this Agreement, Buyer shall send the notice attached as Annex 1 hereto to Continental.

(b)

Prior to the Closing, Seller shall deliver or cause to be delivered to Buyer appropriate instructions for book entry transfers of ownership of the Shares from Seller to Buyer.

(c)

The closing of the purchase and sale of the Shares (“Closing”) will occur on the date on which Buyer’s Trust Account is liquidated in connection with the consummation of the Merger, which consummation shall occur no later than 11:59 p.m. eastern standard time on the seventh day following Seller’s acquisition of the Shares from Buyer’s stockholders (the “Closing Date”). At the Closing, Buyer shall pay Seller the Aggregate Purchase Price and the Fees by wire transfer from Enterprise’s Trust Account of immediately available funds in accordance with the Irrevocable Instructions attached as Annex I hereto to an account specified by Seller and Seller shall deliver the Shares immediately thereafter to Buyer electronically using the Depository Trust Company’s DWAC (Deposit/Withdrawal at Custodian) System to an account specified by Buyer. It shall be a condition to the obligation of Buyer on the one hand and Seller on the other hand, to consummate the transfer of the Shares contemplated hereunder that the other party’s representations and warranties are true and correct on the Closing Date with the same effect as though made on such date, unless waived in writing by the party to whom such representations and warranties are made.

(d)

In the event that the Merger is not consummated by midnight on November 7, 2009 and Buyer has not dissolved and liquidated its assets and paid Seller the liquidation value of its Shares by November 7, 2009, then Buyer shall pay to Seller in immediately available funds, until Buyer liquidates and distributes its assets to its stockholders, an amount equal to the lesser of (i) 4.0% of the Purchase Price Per Share per month (pro-rated on a daily basis based on the date when payment is required and the date such payment is made) or (ii) the highest lawful rate, for each Share held by Seller from the date such payment was required to be made through the date such payment is actually made. Buyer agrees to promptly dissolve and liquidate and distribute its assets in accordance with Delaware law if the Merger is not consummated by 11:59 p.m. eastern standard time on October 30, 2009.

(e)

In the event that the Merger is consummated and Seller has not received the Aggregate Purchase Price and the Fees by the seventh day following Seller’s acquisition of the Shares from Buyer’s Stockholders, then Buyer shall pay to Seller in immediately available funds an amount equal to the lesser of (i) 4.0% of the Purchase Price Per Share per month (pro-rated on a daily basis based on the date when payment is required and the date such payment is made) or (ii) the highest lawful rate, for each Share held by Seller from the date such payment was required to be made through the date such payment is actually made.

(k)

Irrevocable Instructions to Continental. Upon execution of this Agreement, Buyer is delivering the Irrevocable Instructions attached as Annex I to Continental requiring that no funds be released from the Trust Account unless the amounts released from the Trust Account are used to pay in full the amount due to the Seller under this Agreement prior to release of any funds from the Trust Account to Buyer or any other party and Continental has acknowledged and agreed to such Irrevocable Instructions. Seller hereby agrees and consents to the terms of such irrevocable instruction letter. Buyer shall deliver a copy of such Irrevocable Instructions to Seller upon execution of this Agreement.

Upon the replacement of Continental, all references herein to Continental will be to the substitute trustee. Neither the Company shall provide, nor the Insiders shall cause the Company to provide, any instructions with respect to the distribution of the Trust Account that are different from the Irrevocable Instructions without the consent of Seller and all signatories to the Irrevocable Instructions; provided, however, upon written confirmation of Trustee’s compliance with the irrevocable instruction letter and payment of the Aggregate Purchase Price and the Fees to Seller, Buyer may liquidate the Trust Account without further regard to this letter or such irrevocable instructions.

Investments. From the date of this Agreement until all amounts due to the Seller are paid, Buyer agrees to invest the monies in the Trust Account in a money market fund invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940.

(m)

Filings. None of the filings and reports made by Buyer with SEC and available on the SEC’s EDGAR system, as of their respective filing dates, will contain any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. Prior to Closing, Buyer agrees to make all required filings with the SEC under the federal securities laws.

Buyer, ARMOUR and the Insiders agree, jointly and severally, to pay any and all costs, fees and expenses (including counsel fees and expenses) incurred by Seller in enforcing its rights under this Section 8(a).

Buyer and ARMOUR (together with their successors) hereby agree, jointly and severally, to indemnify and hold harmless Seller and each of its partners, principals, members, officers, directors, employees, agents, representatives and affiliated or managed funds from and against any and all losses, claims, damages, liabilities and expenses, joint or several, of any kind or nature whatsoever, and any and all actions, inquiries, proceedings and investigations in respect thereof (including any proceeding by any government subdivision and any claim by any former or current securityholder of Buyer), whether pending or threatened, to which any such party may become subject, arising in any manner out of or in connection with this Agreement or the transactions contemplated herein to the fullest extent permitted under applicable law, regardless of whether any of such parties is a party hereto, and immediately upon request reimburse such party for such party’s legal and other expenses as they are incurred in connection with investigating, preparing, defending, paying, settling or compromising any such action, inquiry, proceeding or investigation (including, without limitation, usual and customary per diem compensation for any such party’s involvement in discovery proceedings or testimony); provided that Buyer and ARMOUR shall not be liable for any such loss, liability, claim, damage or expense resulting from actions taken by Seller in bad faith or as a result of its gross negligence or willful misconduct.

Termination of Purchase Obligation. The obligation of Seller and Buyer to sell and purchase, respectively, the Shares under this Agreement shall become null and void and of no force and effect upon the earlier of (i) the termination of the Merger Agreement or abandonment of the Merger or (ii) 11:59 p.m. eastern standard time on November 7, 2009 if the Merger has not been consummated by such date. Notwithstanding any provision in this Agreement to the contrary, Buyer’s obligation to purchase the Shares from Seller and Seller’s obligation to sell the Shares to Buyer shall be conditioned on the consummation of the Merger.

10.

Covenant of Seller. After the execution of this Agreement and prior to Closing, Seller shall not acquire any common stock, warrants or other securities of Enterprise or effect any derivative transactions with respect thereto.

12.

Counterparts; Facsimile. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same instrument.

Each of the parties hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum and irrevocably waives trial by jury.

14.

Remedies. Each of the parties hereto acknowledges and agrees that, in the event of any breach of any covenant or agreement contained in this Agreement by the other party, money damages may be inadequate with respect to any such breach and the non-breaching party may have no adequate remedy at law. It is accordingly agreed that each of the parties hereto shall be entitled, in addition to any other remedy to which they may be entitled at law or in equity, to seek injunctive relief and/or to compel specific performance to prevent breaches by the other party hereto of any covenant or agreement of such other party contained in this Agreement.

16.

Headings. The descriptive headings of the Sections hereof are inserted for convenience only and do not constitute a part of this Agreement.

17.

Entire Agreement; Changes in Writing. This Agreement constitutes the entire agreement among the parties hereto and supersedes and cancels any prior agreements, representations, warranties, whether oral or written, among the parties hereto relating to the transaction contemplated hereby. Neither this Agreement not any provision hereof may be changed or amended orally, but only by an agreement in writing signed by the other party hereto.

18.
