INTRODUCTORY NOTE.
This Amendment No. 7 to Schedule 13D is being filed on behalf Douglas
A. P. Hamilton ("Mr. Hamilton") to supplement certain information set forth in
the Schedule 13D relating to securities of Carrizo Oil & Gas, Inc., a Texas
corporation (the "Company"), originally filed by Mr. Hamilton on August 21, 1997
and amended by Amendment No. 1 filed on September 9, 1997, Amendment No. 2 filed
on November 21, 1997, Amendment No. 3 filed on January 15, 1998, Amendment No. 4
filed on January 3, 2000, Amendment No. 5 filed on April 10, 2002, and Amendment
No. 6 filed on December 11, 2003 (as so amended, the "Original Statement"), with
respect to the Common Stock, par value $.01 per share (the "Common Stock"), of
the Company. Unless otherwise indicated, each capitalized term used but not
defined herein shall have the meaning assigned to such term in the Original
Statement.
ITEM 4. PURPOSE OF TRANSACTION
On February 11, 2004, Mr. Hamilton sold 249,908 shares of Common Stock
pursuant to the Underwriting Agreement dated February 5, 2004 (the "Underwriting
Agreement") by and among the Company, CIBC World Markets Corp., First Albany
Capital, Inc., Hibernia Southcoast Capital, Inc., and Johnson Rice & Company
L.L.C., as representative of the several underwriters named in Schedule I to the
Underwriting Agreement (the "Underwriters"), and the selling shareholders listed
on Schedule II to the Underwriting Agreement, including Mr. Hamilton, (the
"Selling Shareholders"). Mr. Hamilton sold an additional 67,553 shares of Common
Stock to the Underwriters pursuant to an over-allotment option in the
Underwriting Agreement on March 5, 2004. The price paid by the Underwriters for
shares sold pursuant to the Underwriting Agreement was $6.58 per share, net of
an underwriting discount of $.42 per share.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
Mr. Hamilton beneficially owns an aggregate of 533,011 shares of Common
Stock (approximately 2.88% of the 18,515,559 shares deemed to be outstanding as
of March 5, 2004 (consisting of 18,401,053 shares of Common Stock currently
outstanding and 114,506 shares of Common Stock that can be acquired through the
exercise of options and warrants within 60 days of March 1, 2004)). Mr. Hamilton
is among the beneficiaries of a charitable remainder trust that is the limited
partner of DAPHAM Partnership L.P. (the "Partnership"), which beneficially owns
395,960 shares of Common Stock. Certain trusts established for the benefit of
Mr. Hamilton's children (the "Trusts") beneficially own 78,648 shares of Common
Stock. The Trusts sold 60,000 shares of Common Stock pursuant to the
Underwriting Agreement on February 5, 2004. Mr. Hamilton disclaims beneficial
ownership of the Common Stock held by the Partnership and the Trusts. Mr.
Hamilton's ownership does not include any beneficial ownership that may be
attributed to Mr. Hamilton as a result of his being a party to certain
shareholders agreements described in the Original Statement. As a result of the
transactions described under Item 4, Mr. Hamilton ceased to be the beneficial
owner of more than five percent of the outstanding shares of Common Stock on
February 11, 2004, except to the extent the beneficial ownership of other
shareholders of the Common Stock is attributed to him pursuant to those
shareholder agreements.
ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
SECURITIES OF THE ISSUER.
The Underwriting Agreement includes customary terms and conditions
regarding the sale of securities in a firm commitment underwritten offering,
including an over-allotment option pursuant to which the Underwriters could
purchase up to an additional 73,577 shares of Common Stock from Mr. Hamilton on
or before March 5, 2004. The over-allotment option was exercised, and Mr.
Hamilton sold 67,553 additional shares on March 5, 2004. In addition, pursuant
to the terms of the Underwriting Agreement, Mr. Hamilton and the other Selling
Shareholders agreed not to make any offer, sale, assignment, transfer,
encumbrance, contract to sell, grant of an option to purchase or other
disposition, directly or indirectly, of any Common Stock of the Issuer
beneficially owned on the date of the Underwriting Agreement or thereafter
acquired for a period of 90 days subsequent to the date of the Underwriting
Agreement, subject to certain exceptions, without the prior written consent of
CIBC World Markets Corp. The foregoing description of the Underwriting Agreement
is qualified in its entirety by reference to the text of such agreement, which
is filed as an exhibit to this Schedule 13D and is incorporated by reference
herein.
