Haywood with the Securities and Exchange Commission on July 9, 2002, as amended by Amendment No. 1 to the Schedule 13D filed on August 21, 2002 and Amendment No. 2 to the Schedule 13D filed on October 1, 2002 (the "Schedule 13D"), with respect to the common stock, par value $.01 per share (the "Common Stock"), of Zix Corporation (formerly known as Zixit Corporation) (the "Company"). As previously reported on Amendment No. 2 to the Schedule 13D, on September 18, 2002, Mr. Haywood, purchased (i) 947,708 shares of non-voting Series B Convertible Stock of the Company ("Series B Stock") at $3.60 per share, which are convertible into an aggregate of 902,579 shares of Common Stock at an initial conversion rate of $3.78 per share of Common Stock, and (ii) 305,986 warrants ("Warrants"), at a purchase price of $.125 per Warrant, to purchase an aggregate of 305,986 shares of Common Stock at an initial exercise price of $4.51 per share. As of such date, the Series B Stock was convertible immediately into 388,366 shares of Common Stock; the balance for 514,213 shares of Common Stock was convertible subject to the Company obtaining shareholder approval ("Shareholder Approval") to allow such conversion so as to comply with Nasdaq's 20% issuance limitation. Such Shareholder Approval was obtained at the Company's Special Meeting of Shareholders on January 15, 2003 and, as a result, the balance for 514,213 shares of Common Stock is treated in this Amendment No. 3 as beneficially owned by Mr. Haywood. The Warrants become exercisable March 18, 2003, a date within 60 days of the date of filing this Amendment No. 3, and, accordingly, the underlying Common Stock is now treated as beneficially owned by Mr. Haywood. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) Aggregate number of shares of Common Stock beneficially owned: 5,543,538 Percentage: 25.4%. On a fully diluted basis, treating as outstanding all shares of Common Stock underlying shares of Series A and Series B Preferred Stock of the Company and all shares of Common Stock underlying outstanding warrants and options (without regard to current exercisability), the percentage is 16.7%. (b) 1. Sole power to vote or to direct vote: 5,398,538 (1) 2. Shared power to vote or to direct vote: 145,000 (2) 3. Sole power to dispose or to direct the disposition: 5,398,538 (1) 4. Shared power to dispose or to direct the disposition: 145,000 (2) (1) Represents (A) 4,189,973 shares of Common Stock (of which 11,500 shares are owned by Mr. Haywood's children), (B) 902,579 shares of Common Stock underlying Series B Stock which is immediately convertible, and (C) 305,986 shares of Common Stock underlying the Warrants which are exercisable within the next 60 days. (2) Includes 30,000 shares owned by Mr. Haywood's wife and 115,000 shares owned jointly with Mr. Haywood's mother. (c) No transactions were effectuated since the filing of Amendment No. 2 to the Schedule 13D. This Amendment No. 3 is being filed to reflect the increase in Mr. Haywood's beneficial ownership as a result of (i) the Company obtaining Shareholder Approval to permit conversion of the Series B Stock, and (ii) the Warrants becoming exercisable within 60 days. 3 SIGNATURE After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
