Security and Issuer ------------------- This Amendment No. 1, dated May 12, 1998, to Statement on Schedule 13D, relates to the Common Stock, $0.01 par value per share ("Common Stock"), of North American Scientific, Inc., a Delaware corporation (the "Company"), and is filed by Tudor Investment Corporation, a Delaware corporation ("TIC"), Paul Tudor Jones, II, a natural person and a citizen of the United States ("Mr. Jones"), The Raptor Global Fund Ltd., a company organized under the laws of the Cayman Islands ("Raptor Ltd."), The Raptor Global Fund L.P., a Delaware limited partnership ("Raptor L.P."), Tudor Arbitrage Partners L.P., a Delaware limited partnership ("TAP"), Tudor Global Trading LLC, a Delaware limited liability company ("TGT"), and Tudor BVI Futures, Ltd., a corporation organized under the laws of the British Virgin Islands ("Tudor BVI" and collectively with TIC, Mr. Jones, Raptor Ltd., Raptor L.P., TAP and TGT, the "Reporting Persons").* The summary of information on the schedule attached hereto is qualified in its entirety by reference to such schedule, which is incorporated by reference herein. The Company's principal executive offices are located at 7435 Greenbush Avenue, North Hollywood, CA 91605. Item 5. Interest in Securities of the Issuer. ------------------------------------- Attached hereto as Schedule I is a list of the transactions by each of the Reporting Persons in Common Stock within the past sixty days. Because TIC is the sole general partner of Raptor L.P. and provides investment advisory services to Raptor Ltd., Raptor L.P. and Tudor BVI, TIC may be deemed to beneficially own the shares of Common Stock owned by each of such Reporting Persons. TGT, as the sole general partner of TAP, may be deemed to beneficially own the shares of Common Stock owned by TAP. In addition, because Mr. Jones owns a majority of the capital stock and voting securities of TIC and indirectly owns a majority of the equity interests in TGT, Mr. Jones may be deemed to beneficially own the shares of Common Stock deemed beneficially owned by TIC and TGT. Based on information contained in the Company's Form 10QSB for the quarter ended January 31, 1998 that there were 6,400,802 shares of Common Stock issued and outstanding as of March 13, 1998 (adjusted for a 3 for 2 stock split subsequent to such date), each Reporting Person beneficially owns (or, with - ------------------------- * For purposes of this Statement on Schedule 13D the Reporting Persons have filed as a "group". Nevertheless, the Reporting Persons hereby disclaim that they are members of a "group" for purposes of Section 13(d) of the Securities Exchange Act of 1934 or for any other purpose. respect to TIC, Mr. Jones and TGT, may be deemed to beneficially own) the number and percentage of outstanding shares of Common Stock listed in the responses to Items 11 and 13, respectively, of the cover page filed herewith for such Reporting Person. In addition, the number of shares of Common Stock beneficially owned (or, with respect to TIC, Mr. Jones and TGT, which may be deemed beneficially owned) by each Reporting Person with respect to which such Reporting Person (i) has sole voting power, (ii) shares voting power, (iii) has sole dispositive power and (iv) shares dispositive power are listed in the responses to Items 7, 8, 9 and 10, respectively, of the cover page filed herewith for such Reporting Person. The voting and dispositive power is reported as shared because each of Raptor Ltd., Raptor L.P. and Tudor BVI has the power to remove TIC as its investment advisor or general partner and because TAP has the power to remove TGT as its general partner. Each of Raptor Ltd., Raptor L.P., TAP and Tudor BVI expressly disclaim beneficial ownership of the shares of Common Stock beneficially owned by any other such Reporting Person and each of TIC, Mr. Jones and TGT disclaim beneficial ownership of the Common Stock beneficially owned by Raptor Ltd., Raptor L.P., TAP and Tudor BVI and, in the case of Mr. Jones, TIC and TGT. Following the sales reported on Schedule I, none of the Reporting Persons remained the beneficial owner, pursuant to Rule 13(d)(1)(i), of more than 5% of the Common Stock of the Company. SIGNATURE After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this Amendment No. 1 to Statement on Schedule 13D is true, complete and correct.
