SCHEDULE TO

     This Amendment No. 3 (“Amendment No. 3”) amends and supplements the Tender Offer Statement on Schedule TO (the “Original Schedule TO”) originally filed with the Securities and Exchange Commission (the “SEC”) on October 25, 2010 by Carrizo Oil & Gas, Inc., a Texas corporation (“Carrizo” or the “Company”), as amended and supplemented by Amendment No. 1 thereto (“Amendment No. 1”) filed by Carrizo on November 3, 2010 and Amendment No. 2 thereto (“Amendment No. 2”) filed by Carrizo on November 9, 2010 (the Original Schedule TO, as so amended and supplemented, the “Schedule TO”). The Schedule TO relates to the offer by Carrizo to purchase for cash up to $300 million aggregate principal amount of its outstanding 4.375% convertible senior notes due 2028 (the “Convertible Senior Notes”), or such lesser principal amount of Convertible Senior Notes as is properly tendered and not properly withdrawn, for consideration per $1,000 principal amount of Convertible Senior Notes of $1,000, in addition to any accrued and unpaid interest from the most recent interest payment date to, but not including, the date that Carrizo accepts tendered Convertible Senior Notes for payment. The offer is conditioned on at least $200 million aggregate principal amount of Convertible Senior Notes being validly tendered and not withdrawn. Carrizo’s offer is being made upon the terms and subject to the conditions set forth in the Offer to Purchase dated October 25, 2010 (the “Offer to Purchase”), and in the related Letter of Transmittal (the “Letter of Transmittal” and, together with the Offer to Purchase, each as amended or supplemented from time to time, the “Offer”), copies of which are attached to this Schedule TO as Exhibits (a)(1)(i) and (a)(1)(ii), respectively.

     The purpose of this Amendment No. 3 is to amend and supplement the Schedule TO and the Offer to report the results of the Offer. Only those items amended are reported in this Amendment No. 3. Except as specifically provided herein, the information contained in the Schedule TO and the Offer remains unchanged and this Amendment No. 3 does not modify any of the information previously reported on the Schedule TO. This Amendment No. 3 should be read in conjunction with the Original Schedule TO, Amendment No. 1, Amendment No. 2, the Offer to Purchase and the Letter of Transmittal.

     This Amendment No. 3 is the final amendment to the Schedule TO and is intended to satisfy the reporting requirements of Rule 13e-4(c)(4) of the Securities Exchange Act of 1934, as amended.

     Capitalized terms used and not defined herein have the meanings assigned to them in the Offer to Purchase.

Item 1. Summary Term Sheet.

     The information set forth under “Summary Term Sheet” in the Offer to Purchase and Item 1 of the Schedule TO, to the extent such Item 1 incorporates by reference the information contained in the Offer to Purchase, are hereby amended and supplemented by the information set forth under Item 4, which information is incorporated herein by reference.

Item 4. Terms of the Transaction.

     (a) The Offer to Purchase and Item 4(a) of the Schedule TO, to the extent such Item 4(a) incorporates by reference the information contained in the Offer to Purchase, are hereby amended and supplemented by the following information:

     The Offer expired at 5:00 p.m., New York City time, on November 23, 2010 (the “Expiration Date”). Carrizo has accepted for purchase $300,000,000 aggregate principal amount of Convertible Senior Notes that were validly tendered and not withdrawn as of the Expiration Date for an aggregate consideration of approximately $306,307,292, including accrued and unpaid interest on the Convertible Senior Notes. Because the tender offer was oversubscribed, the aggregate principal amount of Convertible Senior Notes that Carrizo purchased from each tendering noteholder was prorated. Carrizo has been informed by Wells Fargo Bank, National Association, the depositary for the tender offer, that the proration factor is approximately 83.4%. In accordance with the terms of the Offer, the depositary will promptly issue payment for the Convertible Senior Notes accepted for purchase and will return all other Convertible Senior Notes tendered.

     After Carrizo’s purchase of $300,000,000 aggregate principal amount of Convertible Senior Notes, approximately $73,750,000 aggregate principal amount of Convertible Senior Notes will remain outstanding.

     On November 24, 2010, Carrizo issued a press release announcing the results of the Offer. A copy of this press release is attached hereto as Exhibit (a)(5)(v) and is incorporated herein by reference.

Item 7. Source and Amount of Funds or Other Consideration.
