This Amendment constitutes an "exit" filing with respect to the Schedule 13D by the Reporting Persons. Item 1. Security and Issuer. This statement relates to the Common Stock, par value $0.0001 per share (the "Common Stock"), of Kennedy-Wilson Holdings, Inc. (previously known as Prospect Acquisition Corp.), a Delaware corporation (the "Company"). The Company's principal executive offices are located at 9701 Wilshire Blvd., Suite 700, Beverly Hills, California 34109. Item 4. Purpose of the Transaction. Item 4 of the Schedule 13D is hereby amended and supplemented to include the following: On November 12, 2009, the Option Agreement between AMF and Malibu was terminated. Therefore, as of such date there ceased to be any basis for any assertion that the Reporting Persons are a group with the Malibu Reporting Persons. On November 12, 2009, AMF entered into a Stock Purchase Agreement with the Company, which is referenced as Exhibit 3 hereto (which incorporates by reference Exhibit 10.1 to the Current Report filed on Form 8-K by the Company on November 13, 2009) (the "Stock Purchase Agreement"), pursuant to which (i) the Company agreed to buy the Shares from AMF at a fixed price of $9.95 per Share on the date the Company's trust account is liquidated after the Business Combination is consummated and (ii) AMF agreed not to exercise its Redemption Right and not to acquire any Common Stock, warrants or other securities of the Company or effect any derivative transactions with respect thereto. The summary of the Stock Purchase Agreement is not complete, and is qualified in its entirety by reference to the full text of the agreement, which is referenced as Exhibit 3 hereto (which incorporates by reference Exhibit 10.1 to the Current Report filed on Form 8-K by the Company on November 13, 2009). On November 13, 2009, the Company completed a Business Combination. As a result, in accordance with the terms of the Stock Purchase Agreement, the Reporting Persons ceased to have any beneficial ownership of the Shares as of no later than such date. The closing of the sale of the Shares pursuant to the Stock Purchase Agreement will occur on the date the Company's trust account is liquidated. Item 5. Interest in Securities of the Issuer.
