Ladies and Gentlemen:
Carrizo Oil & Gas, Inc., a Texas corporation (the “Company”), proposes to issue and sell to the several underwriters listed on Schedule A hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), 4,500,000 shares (the “Firm Shares”) of the Company’s common stock, $0.01 par value per share (the “Common Stock”).The Company also proposes to sell to the Underwriters at the Underwriters’ option an aggregate of up to 675,000 additional shares of the Common Stock (the “Option Shares”) as set forth below.
The Underwriters have advised the Company that, subject to the terms and conditions contained in this agreement, it is willing to purchase the Firm Shares, plus the Option Shares if the Underwriters elect to exercise the option in whole or in part. The Firm Shares and the Option Shares (to the extent the aforementioned option is exercised) are herein collectively called the “Shares.”
The Company has filed a registration statement on Form S-3 (File No. 333-173821) with respect to the Shares, including a base prospectus (the “Base Prospectus”) to be used in connection with the public offering and sale of the Shares, pursuant to the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations (the “Rules and Regulations”) of the United States Securities and Exchange Commission (the “Commission”) thereunder. As used in this Agreement, “Registration Statement” means, collectively, the various parts of such registration statement, each as amended as of the Effective Date for such part, including any Preliminary Prospectus or the Prospectus and all information deemed to





be part of the registration statement pursuant to Rule 430B or 430C of the Rules and Regulations; “Effective Time” means any time as of which any part of the Registration Statement became, or is deemed to have become, effective under the Securities Act in accordance with the Rules and Regulations; “Effective Date” means the date of the Effective Time; “Preliminary Prospectus” means any preliminary prospectus relating to the Shares included in such registration statement or filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, including the Base Prospectus and any preliminary prospectus supplement thereto relating to the Shares; “Prospectus Supplement” means the prospectus supplement to be filed promptly after the date hereof pursuant to Rule 424 and describing the Shares and the offering thereof (the “Prospectus Supplement”); “Prospectus” means the Prospectus Supplement, together with the Base Prospectus, in the form first used by the Underwriters to confirm sales of the Shares or in the form first made available to the Underwriters by the Company to meet requests of Underwriters pursuant to Rule 173 under the Securities Act; “Free Writing Prospectus” means any “free writing prospectus” as defined in Rule 405 under the Securities Act relating to the Shares; “Issuer Free Writing Prospectus” means any “issuer free writing prospectus” as defined in Rule 433 under the Securities Act relating to the Shares; and “Disclosure Package” means the most recent Preliminary Prospectus, together with the Issuer Free Writing Prospectuses identified on Schedule B hereto, if any, and the information set forth in Schedule C hereto. For purposes of clarity, any Free Writing Prospectus that was prepared by or on behalf of, or used by, an offering participant other than the Company (without regard to whether the conditions set forth in Rule 433 are satisfied with respect thereto) (each, an “Offering Participant Free Writing Prospectus”) shall be excluded from the definitions of Disclosure Package. For the purposes of this Agreement, the “Applicable Time” is 5:15 pm (Eastern Time) on November 6, 2013. Any reference herein to the Registration Statement, any Preliminary Prospectus, the Base Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or before the Effective Date of the Registration Statement, the date of such Preliminary Prospectus, the date of such Base Prospectus, the date of such Prospectus Supplement or the date of the Prospectus, as the case may be, and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include (i) the filing of any document under the Exchange Act after the Effective Date of the Registration Statement, the date of such Preliminary Prospectus, the date of such Base Prospectus, the date of such Prospectus Supplement or the date of the Prospectus, as the case may be, which is incorporated therein by reference and (ii) any such document so filed. For purposes of this Agreement, all references to the Registration Statement, any Preliminary Prospectus, the Base Prospectus, the Prospectus Supplement, the Prospectus or Issuer Free Writing Prospectus or to any amendment or supplement thereto shall be deemed to include any copy filed with the Electronic Data Gathering Analysis and Retrieval System, (“EDGAR”).

No default exists, and no event has occurred which with notice or lapse of time or both would constitute a default, in the due performance and observance of any term, covenant or condition, by the Company or the Subsidiaries, if a Subsidiary is a party thereto, of any other agreement or instrument to which the Company or any of the Subsidiaries is a party or by which Company or its properties or business or a Subsidiary or its properties or business may be bound or affected which default or event, individually or in the aggregate, would have a Material Adverse Effect.

(n)    Absence of Defaults and Conflicts Resulting from Transaction. Neither the execution, delivery and performance of this Agreement nor the consummation of any of the transactions contemplated hereby (including, without limitation, the issuance and sale by the Company of the Shares) will give rise to a right to terminate or accelerate the due date of any payment due under, or conflict with or result in the breach of any term or provision of, or constitute a default (or an event which with notice or lapse of time or both would constitute a default) under, or require any consent or waiver under, or result in the execution or imposition of any lien, charge or encumbrance upon any properties or assets of the Company or the Subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of the Subsidiaries is a party or by which the Company or the Subsidiaries or any of their properties or businesses are bound, or any franchise, license, permit, judgment, decree, order, statute, rule or regulation applicable to the Company or any of the Subsidiaries or violate any provision of the Organizational Documents of the Company or any of the Subsidiaries, except for such consents or waivers which have already been obtained and are in full force and effect and except as would not have a Material Adverse Effect.

The Company and each of the Subsidiaries have fulfilled and performed in all material respects all of their material obligations with respect to such Permits and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other material impairment of the rights of the Company or the Subsidiaries thereunder.

None of the Company or any of the Subsidiaries is involved in any labor dispute nor, to the knowledge of the Company, is any such dispute threatened, which dispute would have a Material Adverse Effect.

2.    Purchase, Sale and Delivery of Shares.
(a)    On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Company agrees to sell to the Underwriters and the Underwriters agree to purchase, at a price of $42.24 per share, the Firm Shares.
(b)    Payment for the Firm Shares to be sold hereunder is to be made to the Company against delivery of the Firm Shares in book-entry form to the Underwriters through the facilities of The Depository Trust Company, New York, New York for the account of the Underwriters. Such payment and delivery are to be made at 10:00 a.m., New York time, on November 13, 2013 or at such other time and date not later than five business days thereafter as the Underwriters and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the New York Stock Exchange is open for trading and on which banks in New York are open for business and are not permitted by law or executive order to be closed. Electronic transfer of the Firm Shares shall be made to the Underwriters at the time of delivery in such names and in such denominations as the Underwriters shall specify to the Company. Deliveries of the documents described in Section 6 hereof with respect to the purchase of the Firm Shares shall be made at the offices of Baker Botts L.L.P., 910 Louisiana Street, Houston, Texas 77002, at or prior to 10:00 A.M., New York time, on the Closing Date.
(c)    In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriters to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and (ii) only once thereafter within 30 days after the date of this Agreement, by the Underwriters to the Company setting forth the number of Option Shares as to which the Underwriters are exercising the option, the names and denominations in which the Option Shares are to be registered and the time and date at which such Option Shares are to be delivered. The time and date at which Option Shares are to be delivered shall be determined by the Underwriters but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is two or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. To the extent, if any, that the option is exercised, payment for and delivery of the Option Shares and delivery of the documents described in Section 6 hereof shall be made in the same manner as in the case of the Firm Shares.
3.    Offering by Underwriters. It is understood that the Underwriters are to make a public offering of the Firm Shares as soon as it deems it advisable to do so.

(a)    Required Filings. The Company covenants and agrees with the Underwriters that it will • prepare and file the Prospectus Supplement with the Commission pursuant to Rule 424, • not file any amendment to the Registration Statement or supplement to the Prospectus or any Issuer Free Writing Prospectus of which the Underwriters shall not previously have been advised and furnished with a copy or to which the Underwriters shall have reasonably objected in writing or which is not in compliance, in all material respects, with the Rules and Regulations, and • file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the termination or completion of the offering of the Shares by the Underwriters; provided, however, that so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is filing reports with the Commission on EDGAR, the Company is not required to furnish such reports or statements to the Underwriters.
(b)    Amendments or Supplements; Stop Orders. The Company will advise the Representatives promptly • when any post-effective amendment to the Registration Statement shall have become effective; • of receipt of any comments from the Commission; • of any request of the Commission for amendment of the Registration Statement or for supplement to the

10




Prospectus or for any additional information; and • of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the use of the Prospectus or of the institution of any proceedings for that purpose. The Company will use its commercially reasonable efforts to prevent the issuance of any such stop order preventing or suspending the use of the Prospectus and to obtain as soon as possible the lifting thereof, if issued.
(c)    Delivery of Copies. The Company will deliver to, or upon the order of, the Representatives during the period when delivery of a Prospectus is required (or, but for the exemption in Rule 172, would be required) under the Securities Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as an Underwriter may reasonably request. The Company will deliver to the Representatives at or before the Closing Date, a signed copy of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representatives such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested) and of all amendments thereto, as an Underwriter may reasonably request.
(d)    Ongoing Compliance. The Company will comply with the Securities Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated by this Agreement and the Prospectus. If during the period in which a prospectus is required (or, but for the exemption in Rule 172, would be required) by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material act necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with the Securities Act or the Rules and Regulations, the Company promptly will prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus.
(e)    Blue Sky Qualifications. The Company will cooperate with the Representatives in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representatives may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided none of the Company or the Subsidiaries shall be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent or subject itself to taxation as doing business in any jurisdiction or qualify as a dealer of securities in any jurisdiction. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representatives may reasonably request for distribution of the Shares.
(f)    Rule 158. The Company will make generally available to its security holders and the Underwriters, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earnings statement shall satisfy the requirements of Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations.
(g)    Investment Company. The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the 1940 Act.
(h)    Payment of Expenses. The Company agrees to pay all costs, expenses and fees incident to the performance of the obligations of the Company under this Agreement, including, without limiting the generality of the foregoing, the following: all fees and expenses of legal counsel to the Company, accountants’ fees of the Company; the cost of printing and delivering to, or as requested by, the Underwriters copies of the Preliminary Prospectus (including any amendments or supplements thereto), any other documents comprising any part of the Disclosure Package and Prospectus; the filing fees of the Commission; the filing fees and expenses (including legal fees and disbursements) incident to securing any required review by FINRA of the terms of the sale of the Shares; the fees and expenses incurred in connection with the registration or qualification of the Shares under the state or foreign securities or blue sky laws of such jurisdictions as the Underwriter may designate; the preparation, printing, authentication, issuance and delivery of the Shares, including any stamp or transfer taxes in connection with the original issuance and sale of the Shares by the Company to the Underwriters; the printing (or reproduction) and delivery of this Agreement and all other agreements or documents approved by the Company and printed (or reproduced) and delivered in connection with the offering of the Shares; the transportation and other expenses of the Company’s officers and employees in connection with presentations to prospective purchasers of the Shares; any listing fee of The Nasdaq Stock Market; and all other costs and expenses of the Company and its representatives incident to the performance by the Company of its obligations hereunder.

11




The Company shall not, however, be required to pay for any of the Underwriters’ expenses (other than those related to qualification under FINRA regulations and state securities or blue sky laws) except that, if this Agreement shall not be consummated because the conditions in Section 6 hereof are not satisfied (except Section 6(e) hereof), or by reason of any failure, refusal or inability on the part of the Company to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on its part to be performed, unless such failure to satisfy said condition or to comply with said terms (i) is due to the default or omission of any Underwriter, or (ii) by reason of a termination of this Agreement by the Representatives as a result of any suspension of trading of any securities of the Company by The Nasdaq Stock Market, the Commission or any governmental authority as contemplated by Section 11(a)(iv) hereof arising out of an action or omission of the Company, then the Company shall reimburse the several Underwriters for reasonable out-of-pocket expenses reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares.
(i)    Nasdaq Listing. The Company will use its best efforts to list, subject to notice of issuance, the Shares on The Nasdaq Stock Market.

The Company covenants and agrees that it will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the SEC a registration statement or amendment to a registration statement under the Securities Act relating to, any shares of its common stock or securities convertible into or exchangeable or exercisable for any shares of its common stock, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing for a period of 45 days after the date of this Agreement, directly or indirectly, otherwise than hereunder or with the prior written consent of the Representatives; provided, that this provision will not restrict the Company from (i) issuances pursuant to the exercise of options outstanding on the date hereof, (ii) grants of employee stock options, restricted stock, restricted stock units, stock-settled stock appreciation rights and other securities issuances pursuant to the terms of a plan in effect on the date hereof, (iii) issuances pursuant to the exercise or vesting of such options, restricted stock units, stock-settled stock appreciation rights or other such securities, (iv) issuances to our employees under the terms of the employee stock purchase plan in effect on the date hereof, (v) issuances pursuant to the Issuer’s 401(k) plan, (vi) issuances to directors pursuant to the incentive plan in effect on the date hereof, (vii) the filing of registration statements on form S-8 and amendments thereto in connection with those securities and plans, (viii) the filing of amendments to the Company’s currently effective shelf registration statement and a new universal shelf registration statement, (ix) issuances pursuant to the exercise or conversion of the Company’s convertible notes, (x) issuances of shares underlying warrants pursuant to the Land Agreement described in the Issuer’s Annual Report form 10-K for the year ended December 31, 2012 and Quarterly Report on Form 10-Q for the quarter ended March 31, 2013, (xi) entering into Rule 10b5-1 trading plans prior to the expiration of the Lock-up Agreements described in Exhibit A but having an effective date for the first sales under such plans after the expiration of such Lock-up Agreements and (xii) the taking of any of the foregoing actions in connection with the issuance of shares or other securities as consideration for acquisitions or in the issuance of securities in private placements by the Issuer.
5.    Free Writing Communications. The Company has not distributed, and without the prior consent of the Underwriters it will not distribute, any prospectus or other offering material (including, without limitation, any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or otherwise constitute a Free Writing Prospectus required to be filed with the Commission and content on the Company’s website that may be deemed to be a prospectus or other offering material) in connection with the offering and sale of the Shares, other than the materials referred to in Section 1(a). The Underwriters represent and agree that they have not made and, without the prior consent of the Company, they will not make, any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or otherwise constitute a free writing prospectus as defined in Rule 405 under the Securities Act and will not include any “issuer information” (as defined in Rule 433) in any free writing prospectus, except as has been disclosed in writing to the Company prior to the Applicable Time.

The Company agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, the Company will give prompt notice thereof to the Underwriters and, if requested by the Underwriters, will prepare and furnish without charge to the Underwriters an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Company by the Underwriters expressly for use therein, such information being listed in Section 7(b) below.

the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in any part of the Registration Statement, the Preliminary Prospectus, the Prospectus or such amendment or supplement thereto, or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representatives specifically for use in the preparation thereof, such information being listed in subsection (b) below; and • to reimburse each Indemnified Party upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Indemnified Party or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Indemnified Party is a party to any action or proceeding. In the event that it is finally judicially determined that such Underwriter was not entitled to receive payments for legal and other expenses pursuant to this subparagraph, such Underwriter will promptly return all sums that had been advanced pursuant hereto.
(a)    Indemnification of Company. Each Underwriter will severally and not jointly indemnify and hold harmless the Company and its directors and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon • any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement, and Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Offering Participant Free Writing Prospectus; or • the omission or the alleged omission of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and will reimburse any legal or other out-of-pocket expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that such Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in any part of the Registration Statement, and Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any Offering Participant Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives specifically for use in the preparation thereof. The Company and the Underwriters acknowledge and agree that the only information furnished or to be furnished on behalf of each Underwriter to the Company for inclusion in any part of the Registration Statement, the Preliminary Prospectus and the Prospectus consists of the first paragraph under the sub-heading “Underwriting Discounts and Expenses”, the first and second paragraphs under the sub-heading “Price Stabilization, Short Positions and Penalty Bids”, the first and second paragraph under the sub-heading “Electronic Distribution” and the first and second paragraphs under the sub-heading “Conflicts of Interest/Relationships” under the captions “Underwriting” in the Preliminary Prospectus and “Underwriting” in the Prospectus.
(b)    Actions against Parties; Notification. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 7(a) or (b) shall be available to any party who shall fail to give notice as provided in this Subsection if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 7(a) or (b). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party and shall pay as incurred the fees and disbursements of such counsel related to such proceeding, and shall not be liable to such indemnified party for any legal or other expenses, except as provided below and except for the reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defense thereof. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the fees and expenses of the counsel retained by the indemnified party in the event •the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, • the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and the indemnified party shall have reasonably concluded that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or • the indemnifying party shall have failed to assume the defense and employ counsel reasonably acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action.

15




It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by the Underwriters in the case of parties indemnified pursuant to Section 7(a) and by the Company in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff (other than a final judgment entered into pursuant to a settlement as to which the indemnifying party did not consent), the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment; provided, however, that if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel in accordance with the provisions hereof, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a) or (b) effected without its written consent if (i) such settlement is entered into in good faith by the indemnified party more than 60 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding and (ii) does not include a statement as to, or an admission of, fault or culpability to act by or on behalf of an indemnified party.
(c)    Contribution. If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters in each case as set forth in the table on the cover page of the Prosepctus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, (i) an Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public exceeds the amount of damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. For purposes of this Section 7(d), each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, the officers of the Company, and each person, if any, who controls the Company within the meaning of the Section 15 of the Securities Act or Section 20 of the Exchange Act, shall have the same rights to contribution as the Company. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 7(d), notify in writing such party or parties from whom contribution may be sought, but the omission to so notify such party or parties from whom contribution

16




may be sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 7(d).
8.    Default of Underwriters. If on the Closing Date any Underwriter or Underwriters hereof shall fail to purchase the portion of the Shares which such Underwriter or Underwriters hereof has agreed to purchase (otherwise than by reason of any default on the part of the Company), you, as Representatives, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company such amounts as may be agreed upon and upon the terms set forth herein, the Shares, as the case may be, which the defaulting Underwriter or Underwriters hereof failed to purchase. If, however, the Representatives shall not have completed such arrangements within such 36-hour period, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to the Underwriters to purchase such Shares on such terms. After giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the Representatives and the Company as provided above, if during such period the Representatives or the Company shall not have procured such other Underwriters, or any others, to purchase the Shares agreed to be purchased by the defaulting Underwriter or Underwriters, then • if the aggregate principal amount of Shares with respect to which such default shall occur does not exceed one-eleventh of the aggregate principal amount of all Shares covered hereby, the other Underwriters shall be obligated, severally, in proportion to the respective principal amount of Shares which they are obligated to purchase hereunder, to purchase the Shares which such defaulting Underwriter or Underwriters failed to purchase, or • if the aggregate principal amount of Shares with respect to which such default shall occur exceeds one-eleventh of the principal amounts of Shares covered hereby, the Company or the Representatives will have the right to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Section 7 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section, the Closing Date may be postponed for such period, not exceeding seven days, as you, as the Representatives, or the Company may determine in order that the required changes in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.
9.    Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations and warranties of the Company and the several Underwriters set forth in or made pursuant to this Agreement, and certifications made by certain officers of the Company pursuant to this Agreement, will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company or any of its representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Shares. If this Agreement is terminated pursuant to Section 11 or if for any reason the purchase of the Shares by the Underwriters is not consummated, the respective obligations of the Company and the Underwriters pursuant to Section 7 shall remain in effect.
10.    Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered or faxed and confirmed to the Underwriters, c/o RBC Capital Markets, LLC, Three World Financial Center, 200 Vesey Street, New York, NY 10281, Attn: Michael Goldberg, Syndicate Director, facsimile: (212) 428-6260; c/o Wells Fargo Securities, LLC 375 Park Avenue New York, New York 10152; c/o Global Hunter Securities, LLC 400 Poydras Street, Suite 3100, New Orleans, LA 70130; or, if sent to the Company, will be mailed, delivered and confirmed to it at Carrizo Oil & Gas, Inc., 500 Dallas Street, Suite 2300, Houston, TX 77002, Attention: Gerald A.

Oshman.
11.    Termination.
(a)    Material Adverse Change. If, subsequent to the execution and delivery of this Agreement, any of the following has occurred: • any change or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business or properties of the Company and the Subsidiaries taken as a whole, which, in the judgment of the Representatives, is material and adverse and makes it impractical or inadvisable to market and deliver the Shares; • any change in U.S. or international financial, political or economic conditions the effect of which is such as to make it, in the judgment of the Representatives, impractical to market or to enforce contracts for the sale of the Shares, whether in the primary market or in respect of dealings in the secondary market; • any suspension or material limitation of trading in securities generally on The Nasdaq Stock Market or the New York Stock Exchange, or any setting of minimum prices for trading on such exchange; • any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; • any downgrading in the rating of any debt securities of the Company by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) as in effect on July 20, 2010), or any public announcement that

17




any such organization has under surveillance or review with possible negative implications its rating of any debt securities of the Company or any announcement that the Company has been placed on negative outlook; • any banking moratorium declared by any U.S. federal or New York state authorities; • any major disruption of settlements of securities, payment, or clearance services in the United States or any other country where such securities are listed; or • any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, except as existing with similar severity on the date hereof involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency is such as to make it impractical or inadvisable to market and deliver the Shares or to enforce contracts for the sale of the Shares, this Agreement may be terminated by the Representatives.
(b)    Costs and Expenses. This Agreement may be terminated by the Representatives as provided in the final paragraph of Section 6 hereof.
12.    Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors, officers, directors and the controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder. No purchaser of any of the Shares from the Underwriters shall be deemed a successor or assign merely because of such purchase.
13.    Representation of Underwriters. You will act for the several Underwriters in connection with this sale and purchase contemplated hereby, and any action under this Agreement taken by you jointly or by RBC Capital Markets, LLC, Wells Fargo Securities, LLC and Global Hunter, as Representatives, will be binding upon all the Underwriters.
In addition, the Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that the Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of its investment bankers. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuer by the Underwriters’ investment banking divisions. The Company acknowledges that the Underwriters are full service securities firms and as such from time to time, subject to applicable securities laws, may effect transactions for their own accounts or the accounts of their customers and hold long or short position in debt or equity securities of the companies which may be the subject to the transactions contemplated by this Agreement.
14.    Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.
15.    Absence of Fiduciary Relationship. The Company acknowledges and agrees that:
(a)    No Other Relationship. The Representatives have been retained solely to act as an initial Underwriter in connection with the sale of the Shares and that no fiduciary, advisory or agency relationship between the Company and the Representatives has been created in respect of any of the transactions contemplated by this Agreement or Prospectus, irrespective of whether the Representatives have advised or are advising the Company on other matters;
(b)    Arm’s-Length Negotiations. The purchase price of the Shares set forth in this Agreement was established by the Company following discussions and arms-length negotiations with the Representatives and the Company is capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;
(c)    Absence of Obligation to Disclose. The Company has been advised that the Representatives and their respective affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Representatives have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and
(d)    Waiver. The Company waives, to the fullest extent permitted by law, any claims it may have against the Representatives for breach of fiduciary duty or alleged breach of fiduciary duty pursuant to this Agreement and agree that the Representatives shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim

18




or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.
16.    Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.
The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. The Company irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.
17.    Entire Agreement. This Agreement, together with all other written agreements of the parties executed on the date hereof in connection with the offering of the Shares, constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof.
18.    Amendment. This Agreement may only be amended or modified in writing, signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.

Ladies and Gentlemen:
This Lock-Up Letter Agreement is being delivered to you in connection with the Underwriting Agreement (the “Underwriting Agreement”) entered into by Carrizo Oil & Gas, Inc. (the “Company”) and you, as representative of the several underwriters listed on Schedule A thereto, with respect to the public offering (the “Offering”) of shares of Common Stock, par value $0.01 per share, of the Company (the “Common Stock”).
The undersigned agrees that, for the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not, without your prior written consent, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, or file (or participate in the filing of) a registration statement with the Securities and Exchange Commission (the “Commission”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder with respect to, any Common Stock of the Company or any securities convertible into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock, whether any such transaction is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, or (iii) publicly announce an intention to elect any transaction specified in clause (i) or (ii). The foregoing sentence shall not apply to (a) bona fide gifts, provided the recipient thereof agrees in writing with you to be bound by the terms of this Lock-Up Letter Agreement, (b) dispositions to any trust for the direct or indirect benefit of the undersigned and/or the immediate family of the undersigned, provided that such trust agrees in writing with you to be bound by the terms of this Lock-Up Letter Agreement, (c) shares of Common Stock subject to bona fide pledges of securities either existing on the date of the lock-up agreement or subsequently entered, if in the latter case the pledgee of such securities agrees in writing to be bound by the transfer restrictions contained in the lock-up agreement with respect to such securities, (d) any sales or option exercises pursuant to Rule 10b5-l trading plans in effect as of the date of the Underwriting Agreement, (e) a number of shares of Common Stock equal to 50% of the number of shares of restricted stock and restricted stock units granted to the undersigned that vest during the Lock-Up Period, (f) sales of shares of Common Stock under any Rule 10b5-1 trading plan to provide funds for the

26




satisfaction of anticipated tax liabilities in contemplation of the vesting of restricted stock and restricted stock units during the 70 days following the date of the Underwriting Agreement, or (g) the execution and delivery of a Rule 10b5-1 plan or amendment to an existing plan provided that the effective date for the first sales under such plan does not occur during the Lock-Up Period. The undersigned further agrees that, during the Lock-Up Period, the undersigned will not, without your prior written consent, make any demand for, or exercise any right with respect to, the registration of Common Stock of the Company or any securities convertible into or exercisable or exchangeable for Common Stock, or warrants or other rights to purchase Common Stock.
The initial Lock-Up Period will commence on the date of this Lock-Up Letter Agreement and continue and include the date 45 days after the public offering date set forth on the final prospectus supplement used to sell the Common Stock (the “Public Offering Date”) pursuant to the Underwriting Agreement, to which you are or expect to become parties.
Notwithstanding anything to the contrary herein, the foregoing restrictions shall not apply to any transactions effected pursuant to a trading plan entered into by the undersigned pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, prior to the date hereof, and nothing herein shall prevent the undersigned from entering into one or more 10b5-1 trading plans or amending one or more existing 10b5-1 trading plans as long as there are no sales of the Company’s common stock under such plans during the Restricted Period.
If (i) the Company notifies you in writing that it does not intend to proceed with the Offering, or (ii) for any reason the Underwriting Agreement shall be terminated prior to the Closing Date (as defined in the Underwriting Agreement), this Lock-Up Letter Agreement shall be terminated and the undersigned shall be released from its obligations hereunder.
Yours very truly,

Exhibit B-1

Form of Opinion of Baker Botts L.L.P.
1.The Company is a corporation validly existing and in good standing under the laws of the State of Texas. The Company has all necessary corporate power and authority to own, lease and operate its properties and to conduct its business as it is now being conducted and as such business is described in the Registration Statement, the Prospectus and the Disclosure Package.
2.    The Company has all requisite corporate power and authority to enter into and perform its obligations under the Underwriting Agreement and to issue and sell the Shares.
3.    The Underwriting Agreement has been duly authorized and validly executed and delivered by the Company.
4.    The Shares, when issued and delivered by the Company against payment of the consideration set forth in the Underwriting Agreement, will be validly issued, fully paid and non-assessable.
5.    The execution and delivery by the Company of the Underwriting Agreement and the consummation of the transactions provided for herein do not and will not with the passage of time (a) result in a breach or violation of any of the terms or provisions of, or constitute a default under the Articles of Incorporation or the Bylaws of the Company; (b) to our knowledge, result in any breach or violation of any terms, provisions or conditions of, or constitute a default of or result in the creation of any lien, charge or encumbrance upon any property or assets of the Company pursuant to any indenture, mortgage, deed of trust, note, contract, commitment, instrument or document filed as an exhibit to the Company’s annual report on Form 10-K, quarterly reports on Form 10-Q or current reports on Form 8-K, in each case as incorporated by reference in the Registration Statement (the “Material Agreements”), except for such contracts for which consents or waivers have been obtained as of the date hereof; or (c) to our knowledge, result in a violation by the Company of any law, statute, rule or regulation of the United States or the State of Texas applicable to the Company (other than securities laws or anti-fraud laws); which, in the case of either (b) or (c), breach, violation, default or creation of a lien, charge or encumbrance would, singularly or in the aggregate, be reasonably expected to have a material adverse effect on the business and operations of the Company or on its legal ability to perform its obligations under the Agreement.
6.    No consent, approval or authorization of, or filing with, any governmental authority or agency of the United States or the State of Texas is required on the part of the Company as a condition to the Company’s valid execution, delivery and performance of its obligations under this Agreement, or to the offer, sale or issuance of the Shares by the Company other than those that have been made or obtained under the Securities Act and the Rules and Regulations or the filing of a prospectus supplement or any issuer information contained in any Offering Participant Free Writing Prospectus on a timely basis with the Commission or as may be required under state securities or “blue sky” laws or by The Nasdaq Stock Market LLC in connection with the sale of the Shares and except for any Form 8-K filing.
7.    The statements in the Registration Statement, Prospectus and Disclosure Package under the caption “Description of Capital Stock” insofar as such statements constitute a summary of the terms of the Common Stock (including the Shares) are accurate summaries of the terms of the Common Stock, in all material respects.
8.    The Registration Statement has been declared effective under the Securities Act. Any required filing of the Preliminary Prospectus and the Prospectus and any supplement thereto pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such Rule 424(b).
9.    The Company is not an “investment company” or an entity controlled by an “investment company” as such terms are defined in the Investment Company Act of 1940, as amended.
We have reviewed the Registration Statement, Prospectus and the Disclosure Package and have participated in conferences with officers and other representatives of the Company, with representatives of the Company’s independent registered public accounting firm and independent petroleum engineers and with your representatives and your counsel, at which the contents of the Registration Statement, the Disclosure Package, Prospectus and related matters were discussed. The purpose of our professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the Disclosure Package or the Prospectus, and we have not undertaken to verify independently any of the factual matters in such documents.

28




Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Disclosure Package and the Prospectus involve matters of a non-legal nature. Accordingly, we are not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, Disclosure Package and the Prospectus (except to the extent stated in paragraphs 7 above). Subject to the foregoing, and on the basis of the information we gained in the course of performing the services referred to above, we advise you that:
(a) the Registration Statement, as of the latest Effective Time, the Preliminary Prospectus, as of the Applicable Time and the Prospectus, as of its date and the date hereof, appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the Rules and Regulations; and
(b) nothing came to our attention that caused us to believe that:
i.
the Registration Statement, as of the latest Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,
ii.
the Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or
iii.
the Prospectus, as of its date and as of the date hereof, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;
it being understood that in each case we have not been asked to, and do not, express any belief with respect to (a) the financial statements and schedules or other financial, accounting or statistical information contained or included or incorporated by reference therein or omitted therefrom, (b) the summary reserve reports of the Company’s independent petroleum engineers and reserve information included or incorporated by reference therein or omitted therefrom or (c) the representations and warranties and other statements of fact contained in the exhibits to the Registration Statement or to the documents incorporated by reference therein.
In connection with our opinion expressed above in paragraph 5, we have reviewed only the Material Agreements and our opinion is limited in all respects to such review.
As to the opinion expressed above in paragraph 1 as to the existence and good standing of the Company, we have relied solely upon certificates issued by the Office of the Secretary of State of Texas and the Office of the Comptroller of the State of Texas.
Our opinion is limited in all respects to matters governed by the Federal laws of the United States and the laws of the State of Texas, in each case as in effect on the date hereof. The opinions expressed herein are for your benefit and may be relied upon only by you for such purposes and may not be given or described to any other person without our prior written consent. The opinions given are strictly limited to the matters stated herein and no implied opinions are to be inferred from anything stated herein, and without limiting the generality of the foregoing we express no opinion with respect to any bankruptcy or creditors rights laws or any federal or state securities or antifraud law, rule or regulation except as otherwise specifically stated herein. This opinion speaks as of the date hereof, and we disclaim any obligation to update this opinion.
