Page 5 of 16 6 STATEMENT ON SCHEDULE 13D Note: All information herein with respect to Carrizo Oil & Gas, Inc., a Texas corporation (the "Issuer"), is to the best knowledge and belief of the Reporting Entities (as defined herein). Items 2, 4, 5 and 7 of the joint Schedule 13D of Enron Corp., Enron Capital & Trade Resources Corp., and Joint Energy Development Investments II Limited Partnership dated March 3, 1998 (the "Initial Schedule 13D") are amended by the addition of the following: Item 2. Identity and Background, Item 4. Purpose of Transaction and Item 5. Interest in Securities of the Issuer. Effective as of December 23, 1998, (i) warrants to purchase 250,000 shares of the Issuer's common stock, par value $.01 per share, (the "Common Stock") held by Enron Capital & Trade Resources Corp. ("ECT"), and (ii) an aggregate of 80,027.63 shares of the Issuer's Series A Preferred Stock (the "Preferred Stock") (including an aggregate of 5,027.63 shares of Preferred Stock issued as dividends on the Preferred Stock) were contributed to the capital of Sundance Assets, L.P., a Delaware limited partnership ("Sundance"), as part of an internal reorganization of the merchant asset portfolio of Enron Corp. ("Enron"), and its subsidiaries and affiliates. The general partner of Sundance is Ponderosa Assets, L.P., a Delaware limited partnership ("Ponderosa"), which is wholly-owned by Enron and certain of its subsidiaries. The general partner of Ponderosa is Enron Ponderosa Management Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of Enron ("EPMH"). Ponderosa, as the general partner of Sundance, and EPMH, as the general partner of Ponderosa, may each be deemed to be controlling persons of Sundance. This Schedule 13D/A amendment is being filed by (i) Sundance (as its initial filing of Schedule 13D) whose principal business is the ownership and management of a diversified portfolio of energy related investments, (ii) ECT, (iii) Enron, and (iv) Joint Energy Development Investments II Limited Partnership, a Delaware limited partnership ("JEDI II"). Sundance, ECT, Enron and JEDI II are referred to herein as the "Reporting Entities." The address of the principal business office of Sundance, Ponderosa and EPMH is 1400 Smith Street, Houston, Texas 77002. Schedule I attached hereto sets forth certain additional information with respect to each director and each executive officer of EPMH. Schedules II, III and IV set forth current information regarding the executive officers and directors of ECT, Enron and Enron Capital II Corp. (the corporate general partner of the general partner of JEDI II) respectively. The filing of this statement on Schedule 13D shall not be construed as an admission that EPMH or any person listed on Schedules I, II, III or IV hereto is, for the purposes of Section 13(d) or 13(g) of the Act, the beneficial owner of any securities covered by this statement. None of the Reporting Entities, nor to their knowledge, Ponderosa or EPMH or any person listed on Schedules I, II, III or IV hereto, has been, during the last five years (a) convicted of any criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or Page 6 of 16 7 prohibiting or mandating activities subject to, U.S. federal or state securities laws or finding any violations with respect to such laws. The warrants to acquire Common Stock (the "Warrants") and the Preferred Stock (which is not publicly traded) were acquired by Sundance as a contribution to its capital upon formation. The Warrants (and any shares of Common Stock issuable upon the exercise thereof) and the Preferred Stock are being held by Sundance for investment purposes. Sundance intends to review its investment in the Issuer on a continuing basis and, depending upon the price of, and other market conditions relating to, the Common Stock, subsequent developments affecting the Issuer, the Issuer's business and prospects, other investment and business opportunities available to Sundance, general stock market and economic conditions, tax considerations and other factors deemed relevant, may decide to increase or decrease the size of its investment in the Issuer. None of the Reporting Entities directly owns any Common Stock. ECT is no longer the record holder of the Warrants. However, Sundance holds the Warrants previously held in the name of ECT which are presently exercisable for 250,000 shares of Common Stock. If the warrants were exercised for Common Stock, the shares of Common Stock issuable upon conversion of such Warrants would represent approximately 2.4% of the outstanding Common Stock (based on the number of shares of Common Stock outstanding as of November 16, 1998 as reported by the Issuer in its Quarterly Report on Form 10-Q for the quarter ended September 30, 1998). Enron and ECT may also be deemed to beneficially own the Warrants held by Sundance and, accordingly, Enron and ECT may be deemed to continue to share beneficial ownership of the 250,000 shares of Common Stock or 2.4% of the Common Stock that would be outstanding upon conversion of the Warrants (based upon the number of shares outstanding as set forth in the Issuer's Quarterly Report filed on Form 10-Q for the Quarter ended September 30, 1998). Because Sundance is controlled by Enron, Sundance is filing this Schedule 13D because it may be deemed to be part of a "group" with Enron, ECT and JEDI II within the meaning of Section 13(d) (3) of the Securities Exchange Act of 1934. Enron disclaims beneficial ownership of the Warrants held by Sundance and JEDI II. ECT and Sundance disclaim beneficial ownership of the Warrants issued to JEDI II. ECT, Ponderosa, EPMH and Enron may be deemed to share voting and dispositive power over the Warrants (and the shares of Common Stock issuable upon exercise thereof) held by Sundance. Other than the transactions described herein, none of the Reporting Entities, nor to their knowledge ECMLP II, ECC II, Ponderosa, EPMH or any of the persons named in the Schedules hereto, has effected any transactions in the Common Stock during the preceding sixty days.
