WITNESSETH

     WHEREAS, the Company wishes to employ the Executive as President and Chief Executive Officer of the Company and the Executive wishes to serve the Company in such capacity.

     NOW, THEREFORE, in consideration of the conditions and covenants set forth herein, it is agreed as follows:

     1.  Employment, Duties and Agreements .

     (a) The Company hereby employs the Executive, and the Executive hereby agrees to be employed by the Company during the Term, as the Company’s President and Chief Executive Officer on the terms and conditions set forth herein, “ Term ” shall mean the period commencing on June 1, 2006 (the “ Effective Date ”) and ending on December 31, 2007; provided , that the Term shall be extended automatically for successive one-year periods, at the rate of Base Salary and on other terms then in effect pursuant to this Agreement, unless written notice of an election not to extend is given by either party to the other at least ninety (90) days prior to the date the Term would then otherwise expire absent its extension; provided , that the Term may be terminated prior to its scheduled expiration date in accordance with Section 3 hereof. Upon any expiration of the Term, the Executive’s employment with the Company shall be at will.

     (b) The Executive shall have such responsibilities and duties as the Board of Directors of the Company (the “ Board ”) may from time to time reasonably determine consistent with the Executive’s position as President and Chief Executive Officer of the Company. In rendering his services hereunder, the Executive shall be subject to, and shall act in accordance with, all reasonable instructions and directions of the Board and all applicable policies and rules thereof. The Executive shall devote the Executive’s full working time to the performance of the Executive’s responsibilities and duties hereunder. During the Term, the Executive will not, without the prior written consent of the Board, render services, whether or not compensated, to any other person or entity as an employee, independent contractor, director or otherwise; provided , however , that nothing herein shall restrict the Executive from rendering services to not-for-profit organizations, including, without limitation, any country club of which he is a member, or managing the Executive’s personal investments during the Executive’s non-working time.

     (c) During the Term, the Executive will not engage in any other business affiliation with respect to any entity, including, without limitation, the establishment of a proprietorship or the participation in a partnership or joint venture, or acquire any equity interest in any entity (other than the Company) if (i) such engagement or ownership would interfere with the full-time performance of his responsibilities and duties hereunder or (ii) such entity is engaged in the business of production, supply or distribution of proppants used in the hydraulic fracturing of natural gas and oil wells or in the provision of fracture or reservoir diagnostic services. The Executive represents and warrants that, as of the Effective Date, the Executive will not be engaged in any such business affiliation and will not own any such equity interests.

     2.  Compensation . During the Term, the Executive shall be entitled to the following compensation.

     (a) Effective as of January 1, 2008, the Company shall pay the Executive a base salary at the rate of $500,000 per annum, payable in accordance with the Company’s normal payroll practices (“ Base Salary ”). The Board shall have the right to review the Executive’s performance and compensation from time to time and may, in its sole discretion, increase his Base Salary based on such factors as the Board deems appropriate.

     (b) The Executive will be paid an incentive bonus with respect to each fiscal year during the Term equal to the sum of (i) 0.5% of the Company’s earnings before interest income and expense and taxes for such fiscal year (“ EBIT ”) up to $75,000,000, plus (ii) 1.0% of EBIT in excess of $75,000,000 (“ Incentive Bonus ”); provided , that with respect to the 2006 fiscal year, Executive’s Incentive Bonus shall be equal to the 2006 fiscal year Incentive Bonus to which Executive would otherwise be entitled pursuant to this Section 2(b) multiplied by a fraction, the numerator of which is the number of days in the period commencing on the Effective Date and ending on the last day of the 2006 fiscal year (inclusive) and the denominator of which is 365. Any such Incentive Bonus shall be paid to the Executive as soon as practicable and in any event no later than the earlier of (i) thirty (30) days after the completion of the audited financial statements and determination of EBIT (the “EBIT Determination Date”) for such fiscal year and (ii) two and one half (2 ¹ /2) months following the end of such fiscal year.

     (c) On the Effective Date, the Company shall grant to the Employee, under the 2004 CARBO Ceramics Inc. Long-Term Incentive Plan (the “Plan”), 20,000 restricted shares of common stock of the Company (the “Restricted Stock”). The grant of the Restricted Stock shall be subject to the terms and conditions of the Plan and the Executive’s Officer Restricted Stock Award Agreement (the form of which is attached hereto as Appendix A).

     (d) The Executive shall be entitled to four (4) weeks of paid vacation during each calendar year of the Term in accordance with the Company’s standard vacation policy and practices. The Executive shall take vacations only at such times as are consistent with reasonable business needs of the Company.

     (e) The Company shall reimburse the Executive for all reasonable, ordinary and necessary expenses incurred by the Executive in the performance of the Executive’s duties hereunder, provided that the Executive accounts to the Company for such expenses in a manner reasonably prescribed by the Company.

     (f) The Executive shall be entitled to such benefits and perquisites as are generally made available to senior executive officers of the Company, provided that the Executive shall not be eligible to participate in the Company’s Incentive Compensation Plan.

     3.  Early Termination of the Term . The Term shall terminate prior to its scheduled expiration date upon the occurrence of any of the following events.

     (a) The Term and the Executive’s employment hereunder shall terminate upon written notice to the Executive by the Company specifying Disability as the basis for such termination. In respect of such termination, the Company shall pay to the Executive (i) within thirty (30) days after such termination, the Executive’s earned but unpaid Base Salary, earned but unused vacation (determined in accordance with the Company’s standard vacation policy and practices) and reimbursement for expenses incurred (in accordance with Section 2(e) hereof), all as of the date of such termination (the “ Accrued Obligations ”), and (ii) as soon as practicable and in any event no later than the earlier of (x) the EBIT Determination Date for the fiscal year in which such termination takes place and (y) two and one half (2 ¹ /2) months following the end of the fiscal year in which such termination takes place, an amount equal to the Incentive Bonus for such fiscal year (calculated in accordance with the first sentence of Section 2(b)) multiplied by a fraction, the numerator of which is the number of days in the period commencing on January 1 of such fiscal year and ending on the date of such termination (inclusive) and the denominator of which is 365 (the “ Termination Bonus Amount ”). The Executive shall not be entitled to any further compensation or payments under this Agreement. “ Disability ” shall mean a physical or mental impairment of the Executive that (A) qualifies the Executive for (x) disability benefits under any long-term disability plan maintained by the Company or (y) Social Security disability benefits or (B) has prevented or, at the date of determination, will reasonably be likely to prevent, the Executive from performing the essential functions of his position for a period of six (6) consecutive months. The existence of a Disability shall be determined by the Board in its absolute discretion. The Executive agrees

to submit to medical examinations by a licensed medical doctor selected by the Board to determine whether a Disability exists, as the Board may request from time to time.

     (b) The Company may terminate the Term and the Executive’s employment hereunder for Cause. Termination for Cause shall be effective upon written notice to the Executive by the Company specifying that such termination is for Cause. In respect of such termination, the Company shall pay to the Executive, within thirty (30) days after such termination, the Accrued Obligations. The Executive shall not be entitled to any further compensation or payments under this Agreement. “ Cause ” shall mean: (i) any material violation by the Executive of this Agreement; (ii) any failure by the Executive substantially to perform his duties hereunder; (iii) any act or omission involving dishonesty, fraud, willful misconduct or gross negligence on the part of the Executive that is or may be materially injurious to the Company; and (iv) any felony or other crime involving moral turpitude committed by the Executive. If the basis for terminating the Executive’s employment for Cause is the result of a violation or failure described in clause (i) or (ii) of the foregoing definition of “Cause” and the majority of the Board (excluding the Executive, if he is a member of the Board) reasonably determines that such violation or failure is capable of being remedied, the Board shall give the Executive thirty (30) days’ prior written notice of the Company’s intent to terminate the Executive’s employment for Cause, which notice shall set forth the violation or failure forming the basis for the determination to terminate the Executive’s employment for Cause. The Executive shall have the right to remedy such violation or failure within a reasonable period of time (as determined by the Board), provided that the Executive begins to take appropriate steps to remedy such violation or failure within ten (10) days of the date of such written notice and diligently prosecutes such efforts thereafter. The Term and the Executive’s employment hereunder may not be terminated for Cause unless a majority of the Board (excluding the Executive, if he is a member of the Board) finds in good faith that termination for Cause is justified and, if the basis for terminating the Executive’s employment for Cause arises as a result of a violation or failure described in clause (i) or (ii) of the definition of “Cause”, that the violation or failure has not been remedied within the period of time designated by the Board or that there is no reasonable prospect that the Executive will remedy the violation or failure forming the basis for terminating his employment for Cause.

     (c) The Term and the Executive’s employment hereunder shall terminate upon the death of the Executive. In respect of such termination, the Company shall pay to the Executive’s estate or any beneficiary previously designated by the Executive in writing (a “ Designated Beneficiary ”) (i) within thirty (30) days after such termination, the Accrued Obligations, and (ii) as soon as practicable and in any event no later than the earlier of (x) the EBIT Determination Date for the fiscal year in which such termination takes place and (y) two and one half (2 ¹ /2) months following the end of the fiscal year in which such termination takes place, an amount equal to the Termination Bonus Amount for such fiscal year. The Executive, his estate and his Designated Beneficiary shall not be entitled to any further compensation or payments under this Agreement.

     (d) The Company may terminate the Term and the Executive’s employment hereunder at any time without Cause. Such termination without Cause shall be communicated by written notice to the Executive from the Company and shall be effective as of the date on which the Executive experiences a “separation from service” within the meaning of Section 1.409A-1(h) of the Treasury Regulations (as amended) promulgated under the United States Internal Revenue Code of 1986 (as amended) (“ Separation from Service ”). In respect of such termination, the Company shall pay to the Executive (i) within thirty (30) days after such Separation from Service, the Accrued Obligations, and (ii) as soon as practicable and in any event no later than the earlier of (x) the EBIT Determination Date for the fiscal year in which such Separation from Service takes place and (y) two and one half (2 ¹ /2) months following the end of the fiscal year in which such Separation from Service takes place, an amount equal to the Termination Bonus Amount for such fiscal year. In addition, in consideration for the Executive’s execution, within seventy-five (75) days following the Executive’s Separation from Service, of a general release of claims in form and substance satisfactory to the Company, the Company shall pay to the Executive (or to the Executive’s

estate or Designated Beneficiary, if the Executive should die during the payout period described in this sentence) an amount equal to two times (2x) the Executive’s Base Salary (at the level in effect immediately preceding such Separation from Service) (the “ Severance Payment ”) as follows: (A) on the seventy-fifth (75 ^th ) day following the Separation from Service, a lump sum equal to the lesser of (I) the Severance Payment or (II) the amount described in Section 1.409A-1(b)(9)(iii)(A) of the Treasury Regulations (as amended) promulgated under the United States Internal Revenue Code of 1986 (as amended) for the year in which the Separation from Service occurs and (B) the remainder of the Severance Payment (if any) in equal installments, in accordance with the Company’s normal payroll practices, over the eighteen (18)-month period commencing on the earlier to occur of (I) the six (6)-month anniversary of the date of the Executive’s Separation from Service or (II) the Executive’s death. The Executive (or his estate or Designated Beneficiary) shall not be entitled to any further compensation or payments under this Agreement. In no event shall any portion of the Severance Payment be paid later than December 31 of the second year following the year in which the Separation from Service occurs. The Severance Payment will not constitute compensation for any purpose under any retirement plan or other employee benefit plan, program, arrangement or agreement of the Company, and no period during which the Severance Payment is being paid shall constitute a period of employment with the Company for any such purposes.

     (e) During the one-year period following a Change in Control of the Company, the Company may terminate the Term and the Executive’s employment hereunder without Cause or the Executive may voluntarily terminate the Term and his employment hereunder for Good Reason. If such termination is made by the Company without Cause, it shall be communicated by written notice to the Executive from the Company and shall be effective upon the Executive’s Separation from Service. In respect of any such termination, in lieu of all other amounts or benefits to which the Executive would otherwise be entitled pursuant to any other provisions of Section 3 of this Agreement, the Company shall pay to the Executive (or to the Executive’s estate or Designated Beneficiary, if the Executive should die during the payout period described in this sentence) (i) within thirty (30) days after such Separation from Service, the Accrued Obligations and (ii) an amount equal to the sum of (A) the Incentive Bonus with respect to the fiscal year immediately preceding the fiscal year in which such Separation from Service takes place (calculated in accordance with the first sentence of Section 2(b)) multiplied by a fraction, the numerator of which is the number of days in the period commencing on January 1 of the fiscal year in which such Separation from Service takes place and ending on the date of such Separation from Service (inclusive) and the denominator of which is 365 and (B) two times (2x) the Executive’s Base Salary (at the level in effect immediately preceding such Separation from Service) (together, the “ CiC Severance Payment ”) as follows: (A) within two and one half (2 ¹ / 2 ) months following the Separation from Service, a lump sum equal to the lesser of (I) the CiC Severance Payment or (II) the amount described in Section 1.409A-1(b)(9)(iii)(A) of the Treasury Regulations (as amended) promulgated under the United States Internal Revenue Code of 1986 (as amended) for the year in which the Separation from Service occurs and (B) the remainder of the CiC Severance Payment (if any) in equal installments, in accordance with the Company’s normal payroll practices, over the eighteen (18)-month period commencing on the earlier to occur of (I) the six (6)-month anniversary of the date of the Executive’s Separation from Service or (II) the Executive’s death. The Executive (or his estate or Designated Beneficiary) shall not be entitled to any further compensation or payments under this Agreement. In no event shall any portion of the CiC Severance Payment be paid later than December 31 of the second year following the year in which the Separation from Service occurs. The CiC Severance Payment will not constitute compensation for any purpose under any retirement plan or other employee benefit plan, program, arrangement or agreement of the Company, and no period during which the CiC Severance Payment is being paid shall constitute a period of employment with the Company for any such purposes.

     (f) For purposes of Section 3(e) hereof:

     (1) “ Change in Control ” shall mean (i) the occurrence of a change in control of the Company of a nature that would be required to be reported or is reported in response to Item 5.01 of the current report on Form 8-K, as in effect on the Effective Date, pursuant to Sections 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “ Exchange Act ”); or (ii) any “ Person ” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 30% or more of the combined voting power of the Company’s outstanding securities (other than any Person who was a “beneficial owner” of securities of the Company representing 30% or more of the combined voting power of the Company’s outstanding securities prior to the Effective Date); or (iii) individuals who constitute the Board on the Effective Date (the “ Incumbent Board ”) cease for any reason to constitute at least a majority of the members of the Board, provided that any person becoming a director subsequent to the Effective Date whose appointment to fill a vacancy or to fill a new Board position was approved by a vote of at least three-quarters of the directors comprising the Incumbent Board, or whose nomination for election by the Company’s shareholders was approved by the same nominating committee serving under an Incumbent Board, shall be, for purposes of this clause (iii), considered as though he were a member of the Incumbent Board; or (iv) the occurrence of any of the following of which the Incumbent Board does not approve (A) merger or consolidation in which the Company is not the surviving corporation or (B) sale of all or substantially all of the assets of the Company; or (v) stockholder approval pursuant to a proxy statement soliciting proxies from stockholders of the Company, by someone other than the then current management of the Company, of a plan of reorganization, merger or consolidation of the Company with one or more corporations as a result of which the outstanding shares of the class of securities then subject to the plan of reorganization are exchanged or converted into cash or property or securities not issued by the Company.

publicly available) unless such information is publicly available by reason of unauthorized disclosure by the Executive or by any person or entity of whose intention to make such unauthorized disclosure the Executive is aware and (ii) information of a general nature not pertaining exclusively to the Company that generally would be acquired in similar employment with another company) constitutes a valuable and confidential asset of the Company. Such information includes, without limitation, information related to trade secrets, customer lists, production techniques, and financial information of the Company. The Executive agrees that he shall, during the Term and continuing thereafter, (A) hold all such information in trust and confidence for the Company and its corporate affiliates, and (B) not use or disclose any such information to any person, firm, corporation or other entity other than under court order or other legal or regulatory requirement.

     (b) Upon expiration of the Term and continuing for a period ending two (2) years after the Executive’s employment by the Company terminates for any reason whatsoever, the Executive agrees that the Executive will not, directly or indirectly, own, manage, operate, control, be employed by (whether as an employee, consultant, independent contractor or otherwise, and whether or not for compensation) or render services to any person, firm, corporation or other entity, in whatever form, engaged in the business of (i) the supply or distribution of proppants used in the hydraulic fracturing of natural gas and oil wells (“ Proppants ”); (ii) the production of Proppants or (iii) the provision of fracture or reservoir diagnostic services, other than BJ Services Company, Schlumberger Limited and Halliburton Company (but only to the extent that the Executive does not engage in activities for these entities related to the exploration, research, development, production or procurement of production of Proppants or the provision of fracture or reservoir diagnostic services).

          (c) During the Term and continuing for a period ending twelve (12) months after the Executive’s employment by the Company terminates for any reason whatsoever, the Executive agrees that the Executive will not, directly or indirectly, individually or on behalf of other persons, solicit, aid or induce (i) then remaining employees of the Company or its corporate affiliates to leave their employment with the Company or its corporate affiliates in order to accept employment with or render services to or with another person, firm, corporation or other entity, or assist or aid any other person, firm, corporation or other entity in identifying or hiring such employees or (ii) any customer of the Company or its corporate affiliates who was a customer of the Company or its corporate affiliates at any time during which the Executive was actively employed by the Company to purchase products or services then sold by the Company or its corporate affiliates from another person, firm, corporation or other entity, or assist or aid any other person or entity in identifying or soliciting any such customer.

          (d) Prior to agreeing to, or commencing to, act as an employee, officer, director, trustee, principal, agent or other representative of any type of business other than as an employee of the Company during the period in which the non-competition agreement, as described in Section 4(b), applies, the Executive shall (i) disclose such agreement in writing to the Company and (ii) disclose to the other entity with which he proposes to act in such capacity, or to the other principal together with whom he proposes to act as a principal, the existence of this Agreement, including, in particular, the non-disclosure agreement contained in Section 4(a), the non-competition agreement contained in Section 4(b), and the non-solicitation agreement contained in Section 4(c).

If the Company or any of its corporate affiliates shall institute any action or proceeding to enforce a restrictive covenant, the Executive hereby waives the claim or defense that the Company or any of its corporate affiliates has an adequate remedy at law and the Executive agrees not to assert in any such action or proceeding the claim or defense that the Company or any of its corporate affiliates has an adequate remedy at law. The foregoing shall not prejudice the Company’s or its corporate affiliates’ right to require the Executive to account for and pay over to the Company or its corporate affiliates, and the Executive hereby agrees to account for and pay over, the compensation, profits, monies, accruals or other benefits derived or received by the Executive as a result of any transaction constituting a breach of the restrictive covenants.

          (f) The restrictions in this Section 4 shall be in addition to any restrictions imposed on the Executive by statute or at common law.

          5. Arbitration of Disputes .

          (a) Any disagreement, dispute, controversy or claim arising out of or relating to this Agreement or the interpretation or validity hereof shall be settled exclusively and finally by arbitration. It is specifically understood and agreed that any disagreement, dispute or controversy which cannot be resolved between the parties, including without limitation any matter relating to interpretation of this Agreement, may be submitted to arbitration irrespective of the magnitude thereof, the amount in controversy or whether such disagreement, dispute or controversy would otherwise be considered justiciable or ripe for resolution by a court or arbitral tribunal. Notwithstanding this Section 5, the Company shall be entitled to institute a court action or proceeding for injunctive relief as provided in Section 4 of this Agreement.

          (b) The arbitration shall be conducted in accordance with the Commercial Arbitration Rules (the “ Arbitration Rules ”) of the American Arbitration Association (“ AAA ”).

          (h) Notwithstanding anything to the contrary in this Agreement, the arbitration provisions set forth in this Section 5 shall be governed exclusively by the Federal Arbitration Act, Title 9, United States Code.
