ACQUISITION OR DISPOSITION OF ASSETS On December 11, 1998, Carrizo Oil & Gas, Inc., a Texas corporation (the "Company") completed the acquisition (the "Acquisition") of certain oil and gas producing properties in Wharton County, Texas, along with certain rights to participate in certain exploration prospects (primarily in the Wilcox formation) in Wharton County, Texas and associated rights of access to certain 2-D and 3-D seismic data and related information and certain other related assets (collectively, the "Assets") from Hall-Houston Oil Company, a Texas corporation, Hall-Houston 1996 Exploration and Development Facility Overriding Royalty Trust, a Texas trust, and Hall-Houston Oil Company Employee Royalty Trust, a Texas trust (collectively, "Hall-Houston"). The Acquisition was effected pursuant to an Agreement dated November 20, 1998 by and between the Company and Hall-Houston (the "Agreement") which is incorporated herein by reference. The consideration for the Acquisition was $3 million cash, subject to certain post-closing adjustments as provided in the Agreement relating to, among other things, oil and gas production from the Assets from an effective date of October 1, 1998. The $3 million consideration was determined by negotiations between the Company and Hall-Houston. There was no material relationship between the Company and Hall-Houston prior to the consummation of the Acquisition. The source of funds for the Acquisition was the term loan arrangement entered into between the Company and Compass Bank in September of 1998 (described in the Company's Form 10-Q for the quarterly period ending September 30, 1998). The Acquisition is not required to be reported under Item 2 of Form 8-K because it does not involve an acquisition of a business that is "significant" as determined under Regulation S-X 11-01(b) by reference to the most recently completed annual fiscal year for the Company and the Assets. The Acquisition is being reported because of its possible significance in relation to the Company's and the Assets' current fiscal year. ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.
