Execution Copy

EMPLOYMENT AGREEMENT

This AGREEMENT (the "Agreement") by and between Carrizo Oil & Gas, Inc., a Texas corporation (the "Company"), and Paul F. Boling (the "Executive"), to be effective as of the 5th day of June, 2009 (the "Agreement Effective Date").

In entering into this Agreement, the Board of Directors of the Company (the "Board") desires to provide the Executive with substantial incentives to serve the Company as one of its senior executives performing at the highest level of leadership and stewardship, without distraction or concern over minimum compensation, benefits or tenure, to manage the Company's future growth and development, and maximize the returns to the Company's stockholders. This Agreement is intended to amend and supersede in its entirety any prior employment agreement between the Executive and the Company (the “Prior Employment Agreement”).

NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

1. Employment Period. As of the Agreement Effective Date, the Company hereby agrees to employ the Executive and the Executive hereby agrees to accept employment with the Company, in accordance with, and subject to, the terms and provisions of this Agreement, for the period (the "Employment Period") commencing on the Agreement Effective Date and ending on the first anniversary of the Agreement Effective Date; provided, on the Agreement Effective Date and on each day thereafter, the Employment Period shall automatically be extended for an additional one day without any further action by either the Company or the Executive, it being the intention of the parties that there shall be continuously a remaining term of not less than one year's duration of the Employment Period until an event has occurred as described in, or one of the parties shall have made an appropriate election and notification pursuant to, the provisions of Section 3.

2. Terms of Employment.

(a) Position and Duties. As of the Agreement Effective Date, the Executive shall become a full time employee and company officer with the title and responsibilities of Chief Financial Officer, Vice President, Secretary and Treasurer and during the Employment Period, excluding any periods of vacation and sick leave to which the Executive is entitled, the Executive agrees to devote full attention and time during normal business hours to the business and affairs of the Company and, to the extent necessary to discharge the responsibilities assigned to the Executive hereunder, to use the Executive's reasonable best efforts to perform faithfully and efficiently such responsibilities. During the Employment Period, it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic, educational, alumni or charitable boards or committees, (B) deliver lectures, fulfill speaking engagements or teach at educational institutions or (C) manage personal investments, so long as such activities do not materially interfere with the performance of the Executive's responsibilities as an employee of the Company in accordance with this Agreement; provided that the Executive may not serve on the board of a publicly traded for profit corporation, or similar body of a publicly traded for profit business organized in other than corporate form, without the consent of the Nominating and Corporate Governance Committee of the Board.

(b) Compensation.

(i) Base Salary. Commencing on the Agreement Effective Date and thereafter during his Employment Period, the Executive shall receive an annual base salary of $237,000 (as such salary may be increased from time to time, the "Annual Base Salary"), which shall be paid on a semimonthly basis. During the Employment Period, the Annual Base Salary shall be reviewed at least annually and shall be increased at any time and from time to time as shall be substantially consistent with increases in base salary generally awarded in the ordinary course of business to executives of the Company and its affiliated companies. Any increase in Annual Base Salary shall not serve to limit or reduce any other obligation to the Executive under this Agreement. As used in this Agreement, the term "affiliated companies" shall include, when used with reference to the Company, any company controlled by, controlling or under common control with the Company.

(ii) Annual Bonus. In addition to Annual Base Salary, the Executive may be awarded, for each fiscal year or portion thereof during the Employment Period, an Annual Bonus (the "Annual Bonus"), in an amount comparable to the Annual Bonus award to other Company executives, taking into account the Executive's position, responsibilities, and accomplishments with the Company, prorated for any period consisting of less than 12 full months.

(iii) Incentive, Savings and Retirement Plans. During the Employment Period, the Executive shall be entitled to participate in all incentive, savings and retirement plans that are tax-qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended ("Code"), and all plans that are supplemental to any such tax-qualified plans, in each case to the extent that such plans are applicable generally to other similarly situated executive employees of the Company and its affiliated companies.

(iv) Welfare Benefit Plans. During the Employment Period, the Executive and/or the Executive's family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Company or its affiliated companies (including, without limitation, medical, prescription, dental, vision, disability, salary continuance, group life and supplemental group life, accidental death and travel accident insurance plans and programs) to the extent applicable generally to other similarly situated executive employees of the Company and its affiliated companies.

(v) Expenses. During the Employment Period, the Executive shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by the Executive in accordance with the policies, practices and procedures of the Company and its affiliated companies.

(vi) Vacation. During the Employment Period, the Executive shall be entitled to paid vacation in accordance with the plans, policies, programs and practices of the Company and its affiliated companies.

3. Termination of Employment.

(a) Death or Disability. The Executive's employment shall terminate automatically upon the Executive's death during the Employment Period. If the Company determines in good faith that the Disability of the Executive has occurred during the Employment Period (pursuant to the definition of Disability set forth below), it may give to the Executive written notice in accordance with Section 13(d) of this Agreement of its intention to terminate the Executive's employment. In such event, the Executive's employment with the Company shall terminate effective on the 30th day after receipt of such notice by the Executive (the "Disability Effective Date"), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive's duties. For the purposes of this Agreement, "Disability" shall mean the absence of the Executive from the Executive's duties with the Company on a full-time basis for either (i) 180 consecutive business days or (ii) in any two-year period 270 nonconsecutive business days as a result of incapacity due to mental or physical illness which is determined to be total and permanent by a physician selected by the Company or its insurers and acceptable to the Executive or the Executive's legal representative (such agreement as to acceptability not to be withheld unreasonably). In the event the Executive incurs a separation from service within the meaning of Treasury Regulation § 1.409A-1(h) as a result of his incapacity, then the Disability Effective Date shall be deemed to be the date of the Executive’s separation from service.

(b) Cause. The Company may terminate the Executive's employment during the Employment Period for Cause. For purposes of this Agreement, "Cause" shall mean for the Company's termination of the Executive's employment for any of the following: (i) the Executive's final conviction of a felony crime that enriched the Executive at the expense of the Company; provided, however, that after indictment, the Company may suspend the Executive from the rendition of services, but without limiting or modifying in any other way the Company's obligations under this Agreement; (ii) a breach by the Executive of a fiduciary duty owed to the Company; (iii) a breach by the Executive of any of the covenants made by him in Sections 8 and 10 hereof; (iv) the willful and gross neglect by the Executive of the duties specifically and expressly required by this Agreement; or (v) the Executive's continuing failure to substantially perform his duties and responsibilities hereunder (except by reason of the Executive's incapacity due to physical or mental illness or injury) for a period of 45 days after the Required Board Majority, as defined herein, has delivered to the Executive a written demand for substantial performance hereunder which specifically identifies the bases for the Required Board Majority's determination that the Executive has not substantially performed his duties and responsibilities hereunder (that period being the "Grace Period"); provided, that for purposes of this clause (v), the Company shall not have Cause to terminate the Executive's employment unless (A) at a meeting of the Board called and held following the Grace Period in the city in which the Company's principal executive offices are located, of which the Executive was given not less than 10 days' prior written notice and at which the Executive was afforded the opportunity to be represented by counsel, appear and be heard, the Required Board Majority shall adopt a written resolution which (1) sets forth the Required Board Majority's determination that the failure of the

Executive to substantially perform his duties and responsibilities hereunder has (except by reason of his incapacity due to physical or mental illness or injury) continued past the Grace Period and (2) specifically identifies the bases for that determination, and (B) the Company, at the written direction of the Required Board Majority, shall deliver to the Executive a Notice of Termination for Cause to which a copy of that resolution, certified as being true and correct by the secretary or any assistant secretary of the Company, is attached. "Required Board Majority" means at any time a majority of the members of the Board at that time which includes at least a majority of the Directors, each of whom has not been an employee of the Company or any subsidiary of the Company.

(c) Good Reason; Window Period; Other Terminations. The Executive's employment may be terminated during the Employment Period by the Executive for Good Reason, or during a Window Period by the Executive without any reason or at any time by the Executive other than for Good Reason or during a Window Period. For the avoidance of doubt, if the Executive remains employed until the beginning of a Window Period, the Executive and the Company agree that the Executive shall resign no later than the end of such Window Period. For purposes of this Agreement, "Window Period" shall mean the 30-day period immediately following elapse of one year after any Change of Control as defined in Section 9 of this Agreement. The Company shall inform the Executive promptly following the occurrence of a Change of Control of the date on which the Change of Control occurred, with such supporting detail as may be necessary to establish such date. For purposes of this Agreement, "Good Reason" shall mean:

(i) the assignment to the Executive of any duties materially inconsistent in any respect with the Executive's position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by Section 2 of this Agreement, or any other action by the Company which results in a material diminution, in absolute terms, in such position, authority, duties or responsibilities, excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Executive;

(ii) any material failure by the Company to comply with any of the provisions of this Agreement, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Executive;

(iii) any purported termination by the Company of the Executive's employment otherwise than as expressly permitted by this Agreement; or

(iv) any failure by the Company to comply with and satisfy the requirements of Section 11 of this Agreement, provided that (A) the successor described in Section 11(c) has received, at least 10 days prior to the Date of Termination (as defined in subparagraph (e) below), written notice from the Company or the Executive of the requirements of such provision and (B) such failure to be in compliance and satisfy the requirements of Section 11 shall continue as of the Date of Termination.

Notwithstanding any provision to the contrary, in order for any event(s) in subparagraph (i) through (iv) above to constitute "Good Reason" for purposes of this Agreement, (A) the Executive must notify the Company via Notice of Termination within 90 days following the initial occurrence of the event(s) that the Executive intends to terminate his employment with the Company because of the occurrence of Good Reason (which event must be described by the Executive in reasonable detail in the Notice of Termination) and (B) within 60 days after receiving such Notice of Termination from the Executive (the “Correction Period”), the Company must fail to reinstate the Executive to the position he was in, or otherwise cure the circumstances giving rise to Good Reason. Executive’s termination for Good Reason may occur only within 60 days following the expiration of the Correction Period.

(d) Notice of Termination. Any termination by the Company for Cause, or by the Executive for Good Reason or without any reason during a Window Period, shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 13 of this Agreement. The failure by the Company to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause shall not waive any right of the Company hereunder or preclude the Company from asserting such fact or circumstance in enforcing the Company’s rights hereunder.

(e) Date of Termination. For purposes of this Agreement, the term "Date of Termination" means (i) if the Executive's employment is terminated by the Company for Cause, or by the Executive during a Window Period or for Good Reason, the date of receipt of the Notice of Termination or any later date specified therein, as the case may be, (ii) if the Executive's employment is terminated by the Company other than for Cause or Disability, the Date of Termination shall be the date on which the Company notifies the Executive of such termination, (iii) if the Executive's employment is terminated by reason of death or Disability, the Date of Termination shall be the date of death of the Executive or the Disability Effective Date, as the case may be and (iv) if the Executive’s employment is terminated by the Executive other than for Good Reason or during a Window Period, the date of termination shall be the date of the receipt of the Notice of Termination or any later date specified therein, but no later than the end of the Window Period.

4. Obligations of the Company upon Termination.

(a) Disability, Good Reason or During a Window Period; Other than for Cause or Death (except during a Window Period). If, during the Employment Period, (x) the Company shall terminate the Executive's employment other than for Cause, including a termination by reason of Disability (but not by reason of death), or (y) the Executive shall terminate employment for Good Reason or (z) his employment shall be terminated during a Window Period by the Company for Cause, by the Executive during a Window Period without any reason, or by reason of death:

(i) the Company shall pay or provide to or in respect of the Executive the following amounts and benefits:

A. in a lump sum in cash, within 10 days after the Date of Termination, an amount equal to the sum of (1) the Executive's Annual

Base Salary through the Date of Termination, (2) any accrued but unpaid Annual Bonus for any prior fiscal year, (3) any deferred compensation previously awarded to or earned by the Executive (together with any accrued interest or earnings thereon), subject to the terms and conditions of any plan or arrangement providing such deferred compensation, and (4) any compensation for unused vacation time for which the Executive is eligible in accordance with the plans, policies, programs and practices of the Company and its affiliated companies, in each case to the extent not theretofore paid (the sum of the amounts described in clauses (1), (2), (3), and (4) shall be hereinafter referred to as the "Accrued Obligation");

B. in a lump sum in cash, within 10 days after the Date of Termination, an amount equal to the Severance Multiplier Percentage (as defined in Exhibit A) multiplied by the Annual Base Salary (provided that if the termination occurs after the date a Change of Control occurs the Executive will be entitled to a lump sum cash payment, within 10 days after the Date of Termination, in an amount equal to the Change of Control Severance Multiplier Percentage (as defined in Exhibit A) of Annual Base Salary);

C. in a lump sum in cash, within 10 days after the Date of Termination, an additional amount equal to the Supplemental Severance Multiplier Percentage (as defined in Exhibit A) of Annual Base Salary multiplied by a fraction, the numerator of which is the number of days in the fiscal year through the Date of Termination and the denominator of which is 365, provided, however, that if the Executive is terminated due to Disability or after the date a Change of Control occurs, the preceding fraction shall be deemed to be equal to 1.0; and

D. effective as of the Date of Termination, (1) immediate vesting and exercisability of, and termination of any restrictions on sale or transfer (other than any such restriction arising by operation of law) with respect to, each and every stock option, restricted stock award, restricted stock unit award and other equity-based award and performance award (each, a “Compensatory Award”) that is outstanding as of a time immediately prior to the Date of Termination and (2) unless a longer post-employment term is provided in the applicable award agreement, the extension of the term during which each and every Compensatory Award may be exercised by the Executive until the earlier of (x) the first anniversary of the Date of Termination or (y) the date upon which the right to exercise any Compensatory Award would have expired if the Executive had continued to be employed by the Company under the terms of this Agreement until the latest possible date of termination of the Employment Period in accordance with the provisions of Section 1 hereof (the “Final Expiration Date”).

Anything in this Agreement to the contrary notwithstanding, if a Change of Control occurs and if the Executive's employment with the Company is terminated within 12 months prior to the date on which the Change of Control occurs, and if it is reasonably demonstrated by the Executive that such termination of employment or cessation of service as an officer (x) was at the request of a third party who has taken steps reasonably calculated to effect the Change of Control or (y) otherwise arose in connection with or anticipation of the Change of Control, then for all purposes of this Agreement, the "date a Change of Control occurs" shall mean the date immediately prior to the date of such termination of employment; provided, however, that the additional Change of Control severance will be paid within 5 days following the occurrence of the Change of Control.

(ii) for the period beginning on the Date of Termination and ending on the Final Expiration Date, or such longer period as any medical or dental plan shall provide, the Company shall continue benefits to the Executive and/or the Executive’s family at least equal to those which would have been provided to them in accordance with the medical and dental plans described in Section 2(b)(iv) of this Agreement if the Executive’s employment had not been terminated in accordance with the medical and dental plans of the Company and its affiliated companies, but with the Company’s medical benefits coverages being secondary to any coverages provided by another employer. In lieu of continued participation in plans, practices, programs and policies described in Section 2(b)(iv) of this Agreement (other than the medical or dental plan, as described above), the Company shall pay the Executive a lump sum payment equal to the Benefits Continuation Multiplier Percentage (as defined in Exhibit A) of the Executive’s Annual Base Salary.

(b) Death (except during a Window Period). If the Executive's employment is terminated by reason of the Executive's death during the Employment Period and other than during a Window Period in which event the provisions of Section 4(a) shall govern, this Agreement shall terminate without further obligations to the Executive's legal representatives under this Agreement, other than (i) the payment of Accrued Obligations (which shall be paid to the Executive's estate or beneficiary, as applicable, in a lump sum in cash within 30 days of the Date of Termination), (ii) providing the Executive with Company-paid term life insurance protection with a death benefit at least equal to the Supplemental Life Insurance Benefit (as defined in Exhibit A) multiplied by the Executive’s Annual Base Salary, with such coverage being supplemental to any other Company-paid group life insurance policy, (iii) during the period beginning on the Date of Termination and ending on the first anniversary thereof medical and dental benefits coverage for the Executive’s dependents determined as if the Executive's employment had not terminated by reason of death, and (iv) effective as of the Date of Termination, (A) immediate vesting and exercisability of, and termination of any restrictions on sale or transfer (other than any such restriction arising by operation of law) with respect to, each and every Compensatory Award outstanding as of the time immediately prior to the Date of Termination, (B) the extension of the term during which each and every Compensatory Award may be exercised or purchased by the Executive until the earlier of (1) the first anniversary of the Date of Termination or (2) the date upon which the right to exercise or purchase any

Compensatory Award would have expired if the Executive had continued to be employed by the Company under the terms of this Agreement until the Final Expiration Date.

(c) Cause; Other than for Disability, Good Reason or During a Window Period. If the Executive's employment shall be terminated for Cause during the Employment Period and other than during a Window Period, in which event the provisions of Section 4(a) shall govern, this Agreement shall terminate without further obligations to the Executive other than for Accrued Obligations. If the Executive terminates employment during the Employment Period, excluding a termination for any Disability, Good Reason or without any reason during a Window Period, in which event the provisions of Section 4(a) shall govern, this Agreement shall terminate without further obligations to the Executive, other than for the payment of Accrued Obligations. In such case, all Accrued Obligations shall be paid to the Executive in a lump sum in cash within 30 days of the Date of Termination.

5. Non-exclusivity of Rights. Except as provided in Section 4 of this Agreement, nothing in this Agreement shall prevent or limit the Executive's continuing or future participation in any plan, program, policy or practice provided by the Company or any of its affiliated companies and for which the Executive may qualify, nor shall anything herein limit or otherwise affect such rights as the Executive may have under any contract or agreement with the Company or any of its affiliated companies. Amounts which are vested benefits or which the Executive is otherwise entitled to receive under any plan, policy, practice or program of or any contract or agreement with the Company or any of its affiliated companies at or subsequent to the Date of Termination shall be payable in accordance with such plan, policy, practice or program or contract or agreement except as such plan, policy, practice or program is superseded by this Agreement.

6. Full Settlement; Resolution of Disputes.

(a) The Company's obligation to make payments provided for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any setoff, counterclaim, recoupment, defense, mitigation or other claim, right or action which the Company may have against the Executive or others. In the event (i) prior to a Change of Control, the Executive's employment is terminated for any reason other than Executive's voluntary termination (with or without Good Reason), or (ii) within two years after a Change of Control, the Executive's employment is terminated by the Company or the Executive for any reason, the Company agrees to pay promptly as incurred, to the full extent permitted by law, all legal fees and expenses which the Executive may reasonably incur as a result of any arbitration pursuant to Section 6(b) (regardless of the outcome thereof) initiated by the Company, the Executive or others regarding the validity or enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive about the amount of any such payment pursuant to this Agreement), plus in each case interest on any delayed payment at the annual percentage rate which is three percentage points above the interest rate shown as the Prime Rate in the Money Rates column in the then most recently published edition of The Wall Street Journal (Southwest Edition), or, if such rate is not then so published on at least a weekly basis, the interest rate announced by Wells Fargo & Company (or its successor), from time to time, as its Base Rate (or prime lending rate), from the date those amounts were required to have been paid or reimbursed to the Employee until those

amounts are finally and fully paid or reimbursed; provided, however, that in no event shall the amount of interest contracted for, charged or received hereunder exceed the maximum non-usurious amount of interest allowed by applicable law; provided, further, that if the Executive is not the prevailing party in any such arbitration, then he shall, upon the conclusion thereof, repay to the Company any amounts that were previously advanced pursuant to this sentence by the Company as payment of legal fees and expenses.

(b) Any dispute arising out of or relating to this Agreement, including the breach, termination or validity thereof, shall be finally resolved by arbitration in accordance with the CPR Institute for Dispute Resolution Rules for Non-Administered Arbitration in effect on the date of this Agreement by a single arbitrator selected in accordance with the CPR Rules. The arbitration shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1-16, and judgment on the award rendered by the arbitrator may be entered by any court having jurisdiction thereof. The place of arbitration shall be in Harris County, Texas. The arbitrator's decision must be based on the provisions of this Agreement and the relevant facts, and the arbitrator's reasoned decision and award shall be binding on both parties. Nothing herein is or shall be deemed to preclude the Company's resort to the injunctive relief prescribed in this Agreement, including any injunctive relief implemented by the arbitrator pursuant to this Section 6(b). The parties will each bear their own attorneys' fees and costs in connection with any dispute, except in the circumstances in which the Company is required to advance the Executive's attorneys' fees in accordance with Section 6(a).

(c) If, upon a termination within two years following a Change of Control, there shall be any dispute between the Company and the Executive concerning (i) in the event of any termination of the Executive's employment by the Company, whether such termination was for Cause or Disability, or (ii) in the event of any termination of employment by the Executive, whether Good Reason existed or whether such termination occurred during a Window Period, then, unless and until there is a final determination by an arbitrator declaring that such termination was for Cause or not for Disability or that the determination by the Executive of the existence of Good Reason was not made in good faith or that the termination by the Executive did not occur during a Window Period, the Company shall pay all amounts, and provide all benefits, to the Executive and/or the Executive's family or other beneficiaries, as the case may be, that the Company would be required to pay or provide pursuant to Section 4(a) hereof as though such termination were by the Company without Cause or by the Executive with Good Reason or during a Window Period; provided, however, that the Company shall not be required to pay any disputed amounts pursuant to this paragraph except upon receipt of an undertaking by or on behalf of the Executive to repay all such amounts to which the Executive is ultimately adjudged by such arbitrator not to be entitled.

(d) Notwithstanding any provision of Section 4, except in the case of a termination of employment within two years following a Change of Control, the Company's obligation to pay the amounts due on any termination of employment under Section 4 (other than the Accrued Obligations) are conditioned on the Executive's execution (without revocation during any applicable statutory revocation period) of a waiver and release of any and all claims against the Company and its affiliates in such form as may be prescribed by the Company.

7. Certain Additional Payments by the Company.

(a) Anything in this Agreement to the contrary notwithstanding and except as set forth below, in the event it shall be determined that any payment or distribution in the nature of compensation (within the meaning of Section 280G(b)(2) of the Code) to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, but determined without regard to any additional payments required under this Section 7 (a "Payment"), would be subject to the excise tax imposed by Section 4999 of the Code, together with any interest or penalties imposed with respect to such excise tax ("Excise Tax"), then the Executive shall be entitled to receive an additional payment (a "Gross Up Payment") in an amount such that, after payment (whether through withholding at the source or otherwise) by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto), employment taxes and Excise Tax imposed upon the Gross Up Payment, the Executive retains an amount of the Gross Up Payment equal to the Excise Tax imposed upon the Payments.

(b) Subject to the provisions of this Section 7, all determinations required to be made under this Section 7, including whether and when a Gross Up Payment is required and the amount of such Gross Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by KPMG LLP(or such other nationally recognized certified public accounting firm that is providing audit services for the Company immediately prior to the date of a Change of Control in replacement of KPMG LLP) (the "Accounting Firm") which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Company. In the event that the Accounting Firm is serving as accountant or auditor for the individual, entity or group effecting the Change of Control or the Accounting Firm declines or is unable to serve, the Executive shall appoint another nationally recognized certified public accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross Up Payment, as determined pursuant to this Section 7, shall be paid by the Company to the Executive within five days of the receipt of the Accounting Firm's determination. If the Accounting Firm determines that no Excise Tax is payable by the Executive, it shall furnish the Executive with a written opinion that failure to report the Excise Tax on the Executive's applicable federal income tax return would not result in the imposition of negligence or similar penalty. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross Up Payments which will not have been made by the Company should have been made ("Underpayment"), consistent with the calculations required to be made hereunder. In the event that the Company exhausts its remedies pursuant to the following provisions of this Section 7 and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive no later than the time such tax is due.

(c) The Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross Up Payment. Such notification shall be given as soon as practicable but no later than 10 business days after the Executive is informed in writing of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30 day period following the date on which it gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall:

(i) give the Company any information reasonably requested by the Company relating to such claim;

(ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company;

(iii) cooperate with the Company in good faith in order to effectively contest such claim; and

(iv) permit the Company to participate in any proceedings relating to such claim;

provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after tax basis, for any Excise Tax, employment tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation of the foregoing provisions of this Section 7, the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs the Executive to pay such claim and sue for a refund, the Company shall provide the amount of such payment to the Executive as an additional payment ("Supplemental Payment") (subject to possible repayment as provided in the next paragraph) and shall indemnify and hold the Executive harmless, on an after tax basis, from any Excise Tax, employment tax or income tax (including interest or penalties with respect thereto) imposed with respect to such payment or with respect to any imputed income with respect thereto; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company's control of the contest shall be limited to issues with respect to which a Gross Up Payment or

Supplemental Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

(d) If, after the receipt by the Executive of an amount provided by the Company pursuant to the foregoing provisions of this Section 7, the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Company complying with the requirements of this Section 7) promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto).

8. Confidential Information. The Executive shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge or data relating to the Company or any of its affiliated companies, and their respective businesses, which shall have been obtained by the Executive during the Executive's employment by the Company or any of its affiliated companies and which shall not be or become public knowledge (other than by acts by the Executive or representatives of the Executive in violation of this Agreement) (referred to herein as "Confidential Information"). After termination of the Executive's employment with the Company, the Executive shall not, without the prior written consent of the Company or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated by it. In no event shall an asserted violation of the provisions of this Section 8 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. Also, within 14 days of the termination of the Executive's employment for any reason, the Executive shall return to Company all documents and other tangible items of or containing Company information which are in the Executive's possession, custody or control, or with respect to equipment that is not Company property that is in the Executive’s possession, custody or control and which contains Confidential Information, the Executive shall purge such Confidential Information from such equipment. Notwithstanding the foregoing, it is understood by the parties that in the course of his employment with the Company the Executive may retain mental recollections or other impressions as a result of having had access to or knowledge of the Company's Confidential Information, and the Company agrees that such retained mental impressions shall not impede or restrict the Executive from engaging in work for a subsequent employer so long as Confidential Information is not expressly disclosed to such subsequent employer.

"Associate" shall mean, with reference to any Person, (a) any corporation, firm, partnership, association, unincorporated organization or other entity (other than the Company or a subsidiary of the Company) of which such Person is an officer or general partner (or officer or

general partner of a general partner) or is, directly or indirectly, the Beneficial Owner of 10% or more of any class of equity securities, (b) any trust or other estate in which such Person has a substantial beneficial interest or as to which such Person serves as trustee or in a similar fiduciary capacity and (c) any relative or spouse of such Person, or any relative of such spouse, who has the same home as such Person.

"Beneficial Owner" shall mean, with reference to any securities, any Person if:

(a) such Person or any of such Person's Affiliates and Associates, directly or indirectly, is the "beneficial owner" of (as determined pursuant to Rule 13d-3 of the General Rules and Regulations under the Exchange Act, as in effect on the date of this Agreement) such securities or otherwise has the right to vote or dispose of such securities, including pursuant to any agreement, arrangement or understanding (whether or not in writing); provided, however, that a Person shall not be deemed the "Beneficial Owner" of, or to "beneficially own," any security under this subsection (a) as a result of an agreement, arrangement or understanding to vote such security if such agreement, arrangement or understanding: (i) arises solely from a revocable proxy or consent given in response to a public (i.e., not including a solicitation exempted by Rule 14a-2(b)(2) of the General Rules and Regulations under the Exchange Act) proxy or consent solicitation made pursuant to, and in accordance with, the applicable provisions of the General Rules and Regulations under the Exchange Act and (ii) is not then reportable by such Person on Schedule 13D under the Exchange Act (or any comparable or successor report);

(b) such Person or any of such Person's Affiliates and Associates, directly or indirectly, has the right or obligation to acquire such securities (whether such right or obligation is exercisable or effective immediately or only after the passage of time or the occurrence of an event) pursuant to any agreement, arrangement or understanding (whether or not in writing) or upon the exercise of conversion rights, exchange rights, other rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the Beneficial Owner of, or to "beneficially own," (i) securities tendered pursuant to a tender or exchange offer made by such Person or any of such Person's Affiliates or Associates until such tendered securities are accepted for purchase or exchange or (ii) securities issuable upon exercise of Exempt Rights; or

(c) such Person or any such Person's Affiliates or Associates (i) has any agreement, arrangement or understanding (whether or not in writing) with any other Person (or any Affiliate or Associate thereof) that beneficially owns such securities for the purpose of acquiring, holding, voting (except as set forth in the proviso to subsection (a) of this definition) or disposing of such securities or (ii) is a member of a group (as that term is used in Rule 13d-5(b) of the General Rules and Regulations under the Exchange Act) that includes any other Person that beneficially owns such securities;

provided, however, that nothing in this definition shall cause a Person engaged in business as an underwriter of securities to be the Beneficial Owner of, or to "beneficially own," any securities acquired through such Person's participation in good faith in a firm commitment underwriting until the expiration of 40 days after the date of such acquisition. For purposes hereof, "voting" a security shall include voting, granting a proxy, consenting or making a request or demand relating to corporate action (including, without limitation, a demand for stockholder list, to call a stockholder meeting or to inspect corporate books and records) or otherwise giving an

authorization (within the meaning of Section 14(a) of the Exchange Act) in respect of such security.

(b) individuals who, as of the Agreement Effective Date, constitute the Board (the "Incumbent Board") cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the Agreement Effective Date whose election, or nomination for election by the Company's shareholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board; provided, further, that there shall be excluded, for this purpose, any such individual whose initial assumption of office occurs as a result of any actual or threatened election contest that is subject to the provisions of Rule 14a-11 under the Exchange Act; or

(c) the Company engages in and completes a reorganization, merger or consolidation, in each case, unless, following such reorganization, merger or consolidation, (i) more than 85% of the then outstanding shares of common stock of the corporation resulting from such reorganization, merger or consolidation and the combined voting power of the then outstanding Voting Stock of such corporation beneficially owned, directly or indirectly, by all or substantially all of the Persons who were the Beneficial Owners of the outstanding Common Stock immediately prior to such reorganization, merger, or consolidation is in substantially the same proportions as their ownership, immediately prior to such reorganization, merger or consolidation, of the outstanding Common Stock, (ii) no Person (excluding any Exempt Person or any Person beneficially owning, immediately prior to such reorganization, merger or consolidation, directly or indirectly, 40% or more of the Common Stock then outstanding or 40% or more of the combined voting power of the Voting Stock of the Company then outstanding) beneficially owns, directly or indirectly, 40% or more of the then outstanding shares of common stock of the corporation resulting from such reorganization, merger or consolidation or the combined voting power of the then outstanding Voting Stock of such corporation and (iii) at least a majority of the members of the board of directors of the corporation resulting from such reorganization, merger or consolidation were members of the Incumbent Board at the time of the

execution of the initial agreement or initial action by the Board providing for such reorganization, merger or consolidation; or

(d) the Company engages in and completes (i) a complete liquidation or dissolution of the Company unless such liquidation or dissolution is approved as part of a plan of liquidation and dissolution involving a sale or disposition of all or substantially all of the assets of the Company to a corporation with respect to which, following such sale or other disposition, all of the requirements of clauses (ii) (A), (B) and (C) of this subsection (d) are satisfied, or (ii) the sale or other disposition of all or substantially all of the assets of the Company, other than to a corporation, with respect to which, following such sale or other disposition, (A) more than 85% of the then outstanding shares of common stock of such corporation and the combined voting power of the Voting Stock of such corporation is then beneficially owned, directly or indirectly, by all or substantially all of the Persons who were the Beneficial Owners of the outstanding Common Stock immediately prior to such sale or other disposition in substantially the same proportion as their ownership, immediately prior to such sale or other disposition, of the outstanding Common Stock, (B) no Person (excluding any Exempt Person and any Person beneficially owning, immediately prior to such sale or other disposition, directly or indirectly, 40% or more of the Common Stock then outstanding or 40% or more of the combined voting power of the Voting Stock of the Company then outstanding) beneficially owns, directly or indirectly, 40% or more of the then outstanding shares of common stock of such corporation and the combined voting power of the then outstanding Voting Stock of such corporation and (C) at least a majority of the members of the board of directors of such corporation were members of the Incumbent Board at the time of the execution of the initial agreement or initial action of the Board providing for such sale or other disposition of assets of the Company.

"Exempt Transaction" shall mean an increase in the percentage of the outstanding shares of Common Stock or the percentage of the combined voting power of the outstanding Voting Stock of the Company beneficially owned by any Person solely as a result of a reduction in the number of shares of Common Stock then outstanding due to the repurchase of Common Stock or Voting Stock by the Company, unless and until such time as (a) such Person or any Affiliate or Associate of such Person shall purchase or otherwise become the Beneficial Owner of additional shares of Common Stock constituting 1% or more of the then outstanding shares of

Common Stock or additional Voting Stock representing 1% or more of the combined voting power of the then outstanding Voting Stock, or (b) any other Person (or Persons) who is (or collectively are) the Beneficial Owner of shares of Common Stock constituting 1% or more of the then outstanding shares of Common Stock or Voting Stock representing 1% or more of the combined voting power of the then outstanding Voting Stock shall become an Affiliate or Associate of such Person.

10. Non-Compete and Non-Solicitation.

(a) The Executive recognizes that in each of the highly competitive businesses in which the Company is engaged, personal contact is of primary importance in securing new customers and in retaining the accounts and goodwill of present customers and protecting the business of the Company. The Executive, therefore, agrees that during the Employment Period and, if the Date of Termination occurs by reason of the Executive terminating his employment for reasons other than Disability or Good Reason and other than during a Window Period, for a period of one year after the Date of Termination, he will not either within 20 miles of any geographic location of any Shale play with respect to which he has devoted substantial attention to the material business interests of the Company or any of its affiliated companies or with respect to any immediate geologic trends in any non-Shale plays, in either case, in which the Company or any of its affiliated companies have active leases or are actively pursuing leases through direct employee activity or hired brokers as of the Date of Termination, without regard, in either case, to whether the Executive has worked at such location (the "Relevant Geographic Area"), (i) accept employment or render service to any Person that is engaged in a business directly competitive with the business then engaged in by the Company or any of its affiliated companies in the Relevant Geographic Area, (ii) enter into or take part in or lend his name, counsel or assistance to any business, either as proprietor, principal, investor, partner, director, officer, executive, consultant, advisor, agent, independent contractor, or in any other capacity whatsoever, for any purpose that would be competitive with the business of the Company or any of its affiliated companies in the Relevant Geographic Area or (iii) regardless of whether it is in the Relevant Geographic Area, directly or indirectly, either as principal, agent, independent contractor, consultant, director, officer, employee, employer, advisor, stockholder, partner or in any other individual or representative capacity whatsoever, either for his own benefit or for the benefit of any other person or entity either (A) hire, contract or solicit, or attempt any of the foregoing, with respect to hiring any employee of the Company or its affiliated companies, or (B) induce or otherwise counsel, advise or encourage any employee of the Company or its affiliated companies to leave the employment of the Company or its affiliated companies (all of the foregoing activities described in (i), (ii) and (iii) are collectively referred to as the "Prohibited Activity"). Notwithstanding anything contained in this Section 10 to the contrary, the Prohibited Activity shall not be applicable to the state or federal waters of the Gulf of Mexico or outside of

the United States except as to the area covered by any U.S. or foreign state or federal oil and gas lease, license or permit in which the Company owns a working interest which was acquired by the Company prior to or during the Employment Period and further limited to the depths in which the Company owns such working or operating rights interest. For the avoidance of doubt, the provisions of this Section 10 will not apply following a termination of the Executive's employment by the Company with or without Cause, by the Executive due to Disability or Good Reason or by the Executive during a Window Period.

(b) In addition to all other remedies at law or in equity which the Company may have for breach of a provision of this Section 10 by the Executive, it is agreed that in the event of any breach or attempted or threatened breach of any such provision, the Company shall be entitled, upon application to any court of proper jurisdiction, to a temporary restraining order or preliminary injunction (without the necessity of (i) proving irreparable harm, (ii) establishing that monetary damages are inadequate or (iii) posting any bond with respect thereto) against the Executive prohibiting such breach or attempted or threatened breach by proving only the existence of such breach or attempted or threatened breach. If the provisions of this Section 10 should ever be deemed to exceed the time, geographic or occupational limitations permitted by the applicable law, the Executive and the Company agree that such provisions shall be and are hereby reformed to the maximum time, geographic or occupational limitations permitted by the applicable law.

(c) The covenants of the Executive set forth in this Section 10 are independent of and severable from every other provision of this Agreement; and the breach of any other provision of this Agreement by the Company or the breach by the Company of any other agreement between the Company and the Executive shall not affect the validity of the provisions of this Section 10 or constitute a defense of the Executive in any suit or action brought by the Company to enforce any of the provisions of this Section 10 or seek any relief for the breach thereof by the Executive.

(d) The Executive acknowledges, agrees and stipulates that: (i) the terms and provisions of this Agreement are reasonable and constitute an otherwise enforceable agreement to which the terms and provisions of this Section 10 are ancillary or a part of as contemplated by TEX. BUS. & COM. CODE ANN. Sections 15.50-15.52; (ii) the consideration provided by the Company under this Agreement is not illusory; and (iii) the consideration given by the Company under this Agreement, including, without limitation, the provision by the Company of Confidential Information to the Executive as contemplated by Section 8, gives rise to the Company's interest in restraining and prohibiting the Executive from engaging in the Prohibited Activity within the Relevant Geographic Area as provided under this Section 10, and the Executive's covenant not to engage in the Prohibited Activity within the Relevant Geographic Area pursuant to this Section 10 is designed to enforce the Executive's consideration (or return promises), including, without limitation, the Executive's promise to not disclose Confidential Information under this Agreement.

11. Successors.

(a) This Agreement is personal to the Executive and without the prior written consent of the Company shall not be assignable by the Executive otherwise than by will or the

laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by the Executive's heirs, executors and other legal representatives.

(b) This Agreement shall inure to the benefit of and be binding upon the Company and may only be assigned to a successor described in Section 11(c).

(c) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. As used in this Agreement, "Company" shall mean the Company as hereinbefore defined and any successor to its business and/or assets as aforesaid which assumes and agrees to perform this Agreement by operation of law, or otherwise.

12. Section 409A.

(a) This Agreement is intended to provide payments that are exempt from or compliant with the provisions of Section 409A of the Code and related regulations and Treasury pronouncements (“Section 409A”), and the Agreement shall be interpreted accordingly. Notwithstanding any provision of this Agreement to the contrary, the parties agree that any benefit or benefits under this Agreement that the Company determines are subject to the suspension period under Code Section 409A(a)(2)(B) shall not be paid or commence until a date following six months after the Executive’s termination date, or if earlier, the Executive’s death.

(b) Each payment under this Agreement is intended to be (i) excepted from Section 409A, including, but not limited to, by compliance with the short-term deferral exception as specified in Treasury Regulation § 1.409A-1(b)(4) and the involuntary separation pay exception within the meaning of Treasury Regulation § 1.409A-1(b)(9)(iii), or (ii) in the event any Gross Up Payment is made pursuant to Section 7(a) herein, in compliance with Section 409A, including, but not limited to, being paid pursuant to a fixed schedule or specified date pursuant to Treasury Regulation § 1.409A-3(i)(1)(v), and the provisions of this Agreement will be administered, interpreted and construed accordingly (or disregarded to the extent such provision cannot be so administered, interpreted, or construed). In the event that any additional tax is imposed on the Executive pursuant to Section 409A, the Company agrees to reimburse the Executive for any such tax imposed by Section 409A, together with any taxes imposed on such reimbursement. Such reimbursement shall be promptly paid by the Company to or for the benefit of the Executive no later than the time such tax is due.

(c) All reimbursements or provision of in-kind benefits pursuant to this Agreement shall be made in accordance with Treasury Regulation § 1.409A-3(i)(1)(iv) such that the reimbursement or provision will be deemed payable at a specified time or on a fixed schedule relative to a permissible payment event. Specifically, the amount reimbursed or in-kind benefits provided under this Agreement during the Executive’s taxable year may not affect the amounts reimbursed or provided in any other taxable year (except that total reimbursements may be limited by a lifetime maximum under a group health plan), the reimbursement of an eligible expense shall be made on or before the last day of the Executive’s taxable year following the

taxable year in which the expense was incurred, and the right to reimbursement or provision of in-kind benefit is not subject to liquidation or exchange for another benefit.

13. Miscellaneous.

(a) This Agreement shall be governed by and construed in accordance with the laws of the State of Texas, without reference to principles of conflict of laws that would require the application of the laws of any other state or jurisdiction.

(b) The captions of this Agreement are not part of the provisions hereof and shall have no force or effect.
