Information in the Schedule 13D remains in effect except to the extent that it is superseded by the information contained in this Amendment No.1. Information given in response to each item shall be deemed to be incorporated by reference in all other items. Capitalized terms used and not defined herein shall have the meanings ascribed to such terms in the Schedule 13D. The items of the Schedule 13D set forth below are hereby amended and supplemented as follows: Item 1. Security and Issuer The first sentence of Item 1 is amended and restated in its entirety as follows: "This statement on Schedule 13D relates to warrants (the "Warrants") to purchase up to 1,785,455 shares of the common stock, par value $0.0001 per share (the "Common Stock"), of Chaparral Resources, Inc. (the "Issuer")." Item 3. Source and Amount of Funds or Other Consideration Item 3 is amended and supplemented by adding the following paragraph after the final paragraph thereof: "In order to clarify certain terms of the Warrants and to give effect to certain changes in the capital structure of the Issuer to satisfy the terms of the Loan Agreement, the Issuer and Shell Capital Limited entered into an amended and restated warrant agreement (the "Amended and Restated Warrant Agreement") on April 18, 2001. Pursuant to the Amended and Restated Warrant Agreement, the Issuer granted to Shell Capital Limited Warrants representing the right to acquire 12.5% of the share capital of the Issuer, exercisable at a price of $9.79 per share, subject to adjustment in accordance with the terms of the Amended and Restated Warrant Agreement. The Amended and Restated Warrant Agreement is attached hereto as Exhibit 1, which is hereby incorporated by reference." Item 4. Purpose of the Transaction Paragraph 1 of Item 4 is amended and restated in its entirety as follows: "Shell Capital Limited acquired the Warrants in connection with its undertaking to underwrite and participate in the funding of the Loan Agreement as described in Item 3. The proceeds of the loan facilities were used to finance the further development of an oil field project in the Republic of Kazakhstan. It was a condition precedent in the Loan Agreement that the Issuer undertakes to nominate as director of the Issuer, on a best efforts basis, a nominee identified by Shell Capital Services Limited (a company in the Group and a wholly-owned subsidiary of The Shell Petroleum Company Limited) for the period during which the loan arrangement remains in place. Furthermore, pursuant to the terms of the Loan Agreement, the Issuer undertook, on a best efforts basis, to complete a rights offering for no less than US$6 million on or before June 30, 2000. As the Issuer satisfied only partially the equity infusion requirements of the Loan Agreement, the Loan Agreement was amended in August 2000 to extend the Issuer's equity support commitment from US$6 million on or before June 30, 2000 to US$10 million on or before September 30, 2000. These revised equity requirements were satisfied through issuances of Common Stock by the Issuer and the acquisition of US$ 3 million of Common Stock by Capco Resourses, Ltd. As a consequence of these changes in the capital structure of the Issuer, the Issuer and Shell Capital Limited deemed it prudent and in their best interest to clarify the terms of the Warrants, and as a result they entered in the Amended and Restated Warrant Agreement to reflect such clarifications deemed necessary and appropriate and to give effect to the changes in the capital structure of the Issuer. The foregoing summary of the Warrant Agreement and the Loan Agreement is qualified in its entirety by reference to Exhibits A, B and C, respectively, which are hereby incorporated by reference." Item 5. Interest in Securities of the Issuer (a) Reference is made to the applicable cover page for each Reporting Person for information concerning (i) the number of shares of Common Stock beneficially owned by such Reporting Person, and (ii) the percentage of outstanding Common Stock beneficially owned by such Reporting Person, in each case as of the date of this filing. (b) Reference is made to the applicable cover page for each Reporting Person for information concerning beneficial ownership of shares of Common Stock as to which such Reporting Person has sole power to vote or to direct the vote, shared power to vote or direct the vote, sole or shared power to dispose or to direct the disposition, in each case as of the date of this filing. (c) During the past sixty days, none of the Reporting Persons acquired or disposed of beneficial ownership of Common Stock except as described herein. (d) No person other than the Reporting Persons has the right to receive dividends on the Common Stock issuable upon exercise of the Warrants beneficially owned by the Reporting Persons described in this Schedule 13D and proceeds from the sale thereof. (e) Not applicable. Item 7. Material to be filed as Exhibits: Exhibit 1 - Amended and Restated Warrant Agreement, dated April 18, 2001 between Chaparral Resources, Inc. and Shell Capital Limited.
