INFORMATION TO BE INCLUDED IN THE REPORT



Item 1.01 Entry into a Material Definitive Agreement



On April 18, 2006, the shareholders of CARBO Ceramics Inc. (the Company) approved amendments (the Amendments) to the 2004 CARBO Ceramics Inc. Long-Term Incentive Plan (the Plan).  The Amendments, which became effective upon shareholder approval, provide for the following modifications:



| | ° | Grant of Restricted Stock to Non-Employee Directors.  Shareholders approved a grant of 2,000 shares of restricted stock to each of the current non-employee Directors of the Company (Messrs. Cooke, Deaton, Lentz, Morris, Murphy and Rubin) on April 18, 2006, and to each future non-employee Director of the Company on the first day that he or she is elected or appointed as a Director.  Unlike employee grants, grants to non-employee Directors will occur regardless of the Companys net income in the immediately preceding calendar year, and one third of such shares will vest on each of the first three anniversaries of the grant date with early vesting upon change in control of the Company or upon termination by reason of death, disability or retirement.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ° | Retirement Provisions.  Under the Plan, in the case of a termination of employment due to death or disability, unvested shares of restricted stock continue to vest for one additional year following termination.  The Amendments provide that upon a termination of employment due to death, disability or retirement, a participants unvested shares will vest on the date of such termination.  The Amendments define retirement as a participants voluntary termination of employment or service on the Board of Directors (with the approval of the Board of Directors) at or after age 62 (unless otherwise defined in a participants award agreement).
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | ° | Administrative Adjustments.  The Amendments made certain clarifications to the definition of Company Affiliate and the dividend payment practice regarding shares of restricted stock, and added a savings clause relating to 409A of the Internal Revenue Code.
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Please refer to the form of restricted stock award agreement for non-employee Directors, amended form of restricted stock award agreement for officer and Amendment Number One to the 2004 CARBO Ceramics Inc. Long-Term Incentive Plan, effective April 18, 2006, which are attached or incorporated herein by reference, for further information.  Such exhibits are incorporated herein by reference in their entirety.
