6 Banque Nationale de Paris ("BNP") and French American Banking Corporation ("FABC") hereby amend their joint Statement on Schedule 13D dated November 10, 1998, as amended by Amendment No. 1 thereto, dated July 20, 1999 ("Amendment No. 1"), Amendment No. 2 thereto, dated September 20, 1999 ("Amendment No. 2"), and Amendment No. 3 thereto, dated November 30, 1999 ("Amendment No. 3"), relating to the common stock, par value $1.00 per share (the "Common Stock"), of BancWest Corporation, a Delaware Corporation (the "Issuer") (such Statement on Schedule 13D as amended, the "Schedule 13D"), as set forth below. All capitalized terms used in this Amendment and not otherwise defined herein have the meanings ascribed to such terms in the Schedule 13D. As more fully described below, since November 25, 1999, the Reporting Person acquired in open market purchases an aggregate of 1,563,138 shares of Common Stock (as adjusted to reflect the 2-for-1 stock split effected by the Issuer on December 15, 1999, in the case of purchases made prior to December 15, 1999) for an aggregate consideration of approximately U.S.$25,609,564 (excluding commissions) in order to maintain its Ownership Percentage in the Issuer. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Item 3 of the Schedule 13D is hereby amended by adding the following at the end thereof: As previously disclosed in Amendment No. 1, Amendment No. 2 and Amendment No. 3 to this Schedule 13D, as a result of a decrease in its Ownership Percentage, the Reporting Person has been acquiring additional Common Stock either through open market purchases or through privately negotiated transactions (the "Restorative Purchases") in order to restore its Ownership Percentage to as much as (but not greater than) 45%, as permitted under the Standstill Agreement. In connection therewith, between November 25, 1999 and February 2, 2000, BNP has acquired in open market transactions an aggregate of 1,563,138 shares of Common Stock (as adjusted to reflect the 2-for-1 stock split effected by the Issuer on December 15, 1999, in the case of purchases made prior to December 15, 1999) (the "Restorative Shares"), for an aggregate consideration of approximately U.S.$25,609,564 (excluding commissions). The Restorative Shares purchased between November 24, 1999 and February 2, 2000 represent, in the aggregate, approximately 1.3% of the total outstanding Common Stock. The source of funds used by BNP to acquire the Restorative Shares, and which will be used to make additional Restorative Purchases, is working capital of the Reporting Person. ITEM 4. PURPOSE OF TRANSACTION. Item 4 of the Schedule 13D is hereby amended by adding the following at the end thereof: Since November 25, 1999, BNP has acquired in the aggregate 1,563,138 shares of Common Stock in order to restore its Ownership Percentage to 45% in accordance with the Standstill Agreement. As the Reporting Person's Ownership Percentage now equals 45%, it will no longer make any Restorative Purchases as long as the Ownership Percentage remains at 45%. On January 26, 2000, BNP converted 2,910,400 shares of Common Stock into an equal number of shares of Class A Common Stock. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. The following paragraph is hereby inserted in lieu of Item 5(a): (a) BNP owns of record 53,459,024 shares of Class A Common Stock (the "BNP Shares") (convertible upon the occurrence of certain circumstances described in Item 6 into 53,459,024 shares of Common Stock). In addition, BNP beneficially owns 1,534,938 shares of Common Stock (convertible at the option of BNP into an equivalent number of shares of Class A Common Stock in accordance with the terms described in the Amended and Restated Certificate of Incorporation of the Issuer and in the Standstill Agreement). FABC owns of record 1,080,912 shares of Class A Common Stock (the "FABC Shares") (convertible upon the occurrence of certain circumstances described in Item 6 of the Schedule 13D into 1,080,912 shares of Common Stock). Collectively, the BNP Shares and the FABC Shares represent 100% of the shares of Class A Common Stock issued and outstanding as of the date hereof (and are convertible upon the occurrence of certain circumstances described in Item 6 of the Schedule 13D into 54,539,936 shares of Common Stock, which shares together with the additional 1,534,938 shares of Common Stock held by BNP equal approximately 45.0% of the shares of Common Stock that would be issued and outstanding upon the conversion of the Class A Common Stock, based upon the number of shares of Common Stock issued and outstanding as of the date hereof and the assumption that the Class A Common Stock currently owned of record by the Reporting Person were to be converted in full). The following paragraph is hereby inserted in lieu of Item 5(b): (b) Subject to the restrictions contained in the Standstill Agreement, (a) BNP has sole voting and investment power with respect to the BNP Shares and any shares of Common Stock into which such shares may be converted under the circumstances described in Item 6, and sole voting and investment power with respect to the 1,534,938 shares of Common Stock held of record by BNP, and BNP has shared voting and investment power with respect to the FABC Shares and any shares of Common Stock into which such shares may be converted under the circumstances described in Item 6, and (b) FABC has shared voting and investment power with respect to the FABC Shares and any shares of Common Stock into which such shares may be converted under the circumstances described in Item 6. Item 5(c) of the Schedule 13D is hereby amended by adding the following at the end thereof: (c) The dates, number of shares and prices per share for all purchases of Common Stock by the Reporting Person from November 25, 1999 through February 2, 2000 are shown on Exhibit I hereto, which is incorporated by reference. All such purchases were made through ML in open market purchases on the New York Stock Exchange. ITEM 7.
