3. Common Stock Repurchase Program

On August 28, 2008, the Company’s Board of Directors authorized the repurchase of up to two million shares of the Company’s Common Stock. Shares are effectively retired at the time of purchase. During the quarter ended March 31, 2012, the Company repurchased and retired 60,000 shares at an aggregate price of $5,726. As of March 31, 2012, the Company has repurchased and retired 1,877,576 shares at an aggregate price of $78,301.

4. Dividends Paid

On January 17, 2012, the Board of Directors declared a cash dividend of $0.24 per common share payable to shareholders of record on February 1, 2012. The dividend was paid on February 15, 2012. On March 20, 2012, the Board of Directors declared a cash dividend of $0.24 per common share payable to shareholders of record on May 1, 2012. The dividend is payable on May 15, 2012 and is presented in Current Liabilities at March 31, 2012.

5. Stock Based Compensation

The CARBO Ceramics Inc. Omnibus Incentive Plan (the “Omnibus Incentive Plan”) provides for granting of cash-based awards, stock options (both non-qualified and incentive) and other equity-based awards (including stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares, deferred share units or share-denominated performance units) to employees and non-employee directors. The amount paid under the Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $2,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 750,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 50,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) in equal annual installments over a three-year period but subject to certain limitations, awards may specify other vesting periods. As of March 31, 2012, 568,606 shares were available for issuance under the Omnibus Incentive Plan. Although the Company’s previous stock option plan has expired, outstanding options granted under the plan remain outstanding in accordance with their terms.

As of March 31, 2012, all compensation cost related to stock options granted under the expired stock option plan has been recognized. There were no stock options exercised during the three months ended March 31, 2012. The weighted-average remaining contractual term of the 2,425 options outstanding at March 31, 2012 was approximately 6 months.

A summary of restricted stock activity and related information for the three months ended March 31, 2012 is presented below:

	Shares			Weighted- Average Grant-Date Fair Value
Nonvested at January 1, 2012		129,082		$	75.00
Granted		55,652		$	119.22
Vested		(58,461	)	$	66.15
Forfeited		(1,061	)	$	108.28
Nonvested at March 31, 2012		125,212		$	98.51

As of March 31, 2012, there was $9,322 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under the Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.9 years. The total fair value of shares vested during the three months ended March 31, 2012 was $3,867.

8

The Company has made phantom stock awards to key international employees pursuant to the Omnibus Incentive Plan. The units subject to an award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom shares are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued with regard to outstanding phantom shares. As of March 31, 2012, there were 10,105 units of phantom shares granted under the Omnibus Incentive Plan, of which 3,429 have vested and 1,076 have been forfeited, with a total value of $591, a portion of which is accrued as a liability within Other Accrued Expenses.

6. Bank Borrowings

The Company has an unsecured revolving credit agreement with a bank. Under the terms of the agreement, as amended on March 5, 2012, the Company can borrow up to $25,000. The Company has the option of choosing either the bank’s fluctuating Base Rate or LIBOR Fixed Rate, plus an Applicable Margin, all as defined in the credit agreement. The terms of the credit agreement provide for certain affirmative and negative covenants and require the Company to maintain certain financial ratios. Commitment fees are payable quarterly at the annual rate of 0.50% of the unused line of credit. During the three-month period ended March 31, 2012, the Company borrowed and repaid $10,000 under the line of credit.

7. Foreign Currencies

As of March 31, 2012, the Company’s net investment that is subject to foreign currency fluctuations totaled $91,368 and the Company has recorded a cumulative foreign currency translation loss of $725, net of deferred income tax benefit. This cumulative translation loss is included in Accumulated Other Comprehensive Loss.

8. New Accounting Pronouncements

In December 2010, the FASB issued authoritative guidance on application of goodwill impairment model when a reporting unit has a zero or negative carrying amount. When a reporting unit has a zero or negative carrying value, Step 2 of the goodwill impairment test should be performed if qualitative factors indicate that it is more likely than not that a goodwill impairment exists. The guidance is effective for the Company beginning in the first quarter of fiscal 2012. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

In December 2010, the FASB issued authoritative guidance on disclosure of supplementary pro forma information for business combinations. The new guidance requires that pro forma financial information should be prepared as if the business combination occurred as of the beginning of the prior annual period. The guidance is effective for the Company for business combinations with acquisition dates occurring in and from the first quarter of fiscal 2012. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.

9. Legal Proceedings

The Company is subject to legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows.

On August 4, 2011, CARBO Ceramics Inc. was named as a defendant in a civil lawsuit filed by C-E Minerals, Inc. (“C-E”) in the United States District Court for the Northern District of Georgia, Atlanta Division. C-E alleged that a mutual non-competition provision contained in a Raw Material Requirements Agreement between C-E and CARBO Ceramics Inc., dated June 1, 2003, was invalid under federal antitrust law and applicable state law. On March 13, 2012, the Court granted a preliminary injunction in favor of C-E. The Company and C-E subsequently entered into a settlement agreement by which both parties agreed not to enforce the covenant against the other, and resolved the claims asserted in the lawsuit. As a result, the lawsuit has been dismissed. There was no material impact to the financial statements as a result of this lawsuit.

On February 9, 2012, the Company and two of its officers, Gary A. Kolstad and Ernesto Bautista III, were named as defendants in a purported class-action lawsuit filed in the United States District Court for the Southern District of New York (the “February SDNY Lawsuit”), brought on behalf of shareholders who purchased the Company’s Common Stock between October 27, 2011 and January 26, 2012 (the “Relevant Time Period”). The suit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations

9

and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”). On April 19, 2012, a third purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of Texas, which was also brought on behalf of shareholders who purchased the Company’s Common Stock during the Relevant Time Period (the “April SDTX Lawsuit” and collectively with the April SDNY Lawsuit and the February SDNY Lawsuit, the “Federal Securities Lawsuits”). The April SDNY Lawsuit and the April SDTX Lawsuit allege substantially similar claims as the February SDNY Lawsuit and request unspecified damages and costs.

On March 1, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “Harris County Lawsuit”). The suit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit. The derivative lawsuit requests unspecified damages and costs. The parties to this lawsuit have entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuits.

While each of the Federal Securities Lawsuits and the Harris Country Lawsuit are in their preliminary stages, the Company does not believe they have merit, and plans to vigorously contest and defend against them.

The Company cannot predict the ultimate outcome or duration of these lawsuits.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Business

The Company generates revenue primarily through the sale of products and services to the oil and natural gas industry. The Company’s principal business consists of manufacturing and selling ceramic proppant and resin-coated sand for use primarily in the hydraulic fracturing of oil and natural gas wells. The Company also provides the industry’s most popular hydraulic fracture simulation software FracPro^®, as well as hydraulic fracture design and consulting services. In addition, the Company provides a broad range of technologies for spill prevention, containment and countermeasures, along with geotechnical monitoring.

Critical Accounting Policies

The consolidated financial statements are prepared in accordance with United States generally accounting principles, which require the Company to make estimates and assumptions (see Note 1 to the consolidated financial statements included in the annual report on Form 10-K for the year ended December 31, 2011). The Company believes that some of its accounting policies involve a higher degree of judgment and complexity than others. As of December 31, 2011, critical accounting policies for the Company included revenue recognition, estimating the recoverability of accounts receivable, inventory valuation, accounting for income taxes and accounting for long-lived assets. These critical accounting policies are discussed more fully in the Company’s annual report on Form 10-K for the year ended December 31, 2011. There have been no changes in the Company’s evaluation of its critical accounting policies since December 31, 2011.

Results of Operations

Three Months Ended March 31, 2012

Revenues. Revenues of $163.2 million for the first quarter of 2012 increased 8% compared to $150.8 million for the same period in 2011. The increase is mainly attributed to a 6% increase in the average proppant selling price as a result of price increases during 2011, an increase in proppant sales volume and an increase in revenues of some of the Company’s other business units. Worldwide proppant sales volume totaled 404 million pounds in the first three months of 2012 compared to 399 million pounds for the same period in 2011. North American (defined as Canada and the U.S.) sales volume decreased 2% due primarily to the shift in U.S. drilling activity from natural gas basins, including certain shale plays, to oily, liquids-rich basins. International (excluding Canada) sales volume increased 21%. Other Proppants (resin-coated sand and ceramic proppant manufactured on an outsourced basis) represented 42 million pounds of the Company’s worldwide sales volumes in the first quarter of 2012, as compared to 23 million pounds in the first quarter of 2011. The average selling price per pound of all proppant was $0.372 during the first quarter of 2012 compared to $0.351 for the same period in 2011.

Gross Profit. Gross profit for the first quarter of 2012 was $63.5 million, or 39% of revenues, compared to $62.1 million, or 41% of revenues, for the first quarter of 2011. The increase in gross profit was primarily the result of an increase in the average proppant selling price and a greater contribution from some of the Company’s other business units. Gross profit as a percentage of revenues decreased primarily as a result of higher freight and logistics costs and a change in the mix of products sold.

Selling, General and Administrative (SG&A) and Other Operating Expenses. SG&A expenses totaled $16.7 million for the first quarter of 2012 compared to $14.3 million for the first quarter of 2011. As a percentage of revenues, SG&A expenses increased to 10.2% in 2012 compared to 9.5% for the first quarter of 2011. The increase in SG&A expenses primarily resulted from higher marketing, research and development, and administrative spending. Start-up costs of $0.1 million in 2012 related to the start-up of the second resin-coating line at the Company’s New Iberia, Louisiana facility. Loss on disposal or impairment of assets of $1.7 million in 2011 consists of a $0.9 million impairment of goodwill related to the Company’s geotechnical monitoring business and a $0.8 million write-down of a 6% interest in an investment accounted for under the cost method, as a result of the sale of the business by majority shareholders.

Other Income (Expense). Other expense for the first quarter of 2012 increased $0.5 million compared to the same period in 2011. This increase is mainly attributed to losses resulting from changes in exchange rates between the functional currency and the foreign currency in which the effective transactions were denominated.

11

Outlook

The Company believes its operating results for the remainder of 2012 will continue to be influenced by the level of oil and natural gas drilling in North America. A severe decline in natural gas prices in the U.S. in late 2011 led businesses engaged in the exploration and production of oil and natural gas to reduce drilling activity and capital spending in natural gas basins, including shale plays, and to increase capital spending towards oily, liquids-rich basins. From the Company’s perspective, the industry’s response to the reallocation of proppant supply and demand and adjustments to the increased supply and decreased prices for natural gas will take some time to work out, and the exact timing of this response is not certain.

While natural gas prices remain low, the continuing shift in oilfield activity by the Company’s clients to oily, liquids-rich plays is encouraging, and the Company believes that demand for high-conductivity ceramic proppant will continue to strengthen. However, due to the continued industry relocation of equipment, services and supplies to liquids-rich basins, the Company anticipates pricing pressures will become more evident over the remainder of the year. In addition, the increased amount of activity in infrastructure-limited, liquids-rich basins introduced supply chain challenges to the industry. These challenges resulted in higher supply chain costs in the first quarter of 2012 for the Company.

The Company expects to support near-term demand with its current ceramic production capacity of 1.7 billion pounds per year, along with existing inventories of ceramic proppant that meets API/ISO standards manufactured on an outsourced basis. With respect to resin-coating capacity expansion, the second production line in New Iberia, Louisiana was completed during the first quarter of 2012 and increased the Company’s annual resin-coating capacity to 400 million pounds. Production output, however, continues to be limited by the availability of third-party supplied northern white sand that meets the Company’s specifications. The Company expects to utilize its own northern white sand reserves in the third quarter of 2012 as it brings on its sand processing facility in Marshfield, Wisconsin. With respect to the resin-coating expansion in Marshfield, the Company has slowed this project by approximately six months and now anticipates this operation may commence by the end of the first half of 2013. Additionally, the Company has been issued an Air Quality Permit for its proposed ceramic proppant manufacturing plant in Millen, Georgia. The Company is moving forward with construction of the first 250 million pound line and anticipates the Millen plant could commence operations near the end of 2013.

Liquidity and Capital Resources

At March 31, 2012, the Company had cash and cash equivalents of $32.0 million compared to cash and cash equivalents of $41.3 million at December 31, 2011. During the first quarter of 2012, the Company generated $29.3 million of cash from operating activities, retained $1.3 million from excess tax benefits relating to stock based compensation and retained $0.4 million from the effect of exchange rate changes on cash. Uses of cash included $27.0 million for capital expenditures, $5.6 million for the payment of cash dividends and $7.7 million for repurchases of the Company’s Common Stock. In addition, during the first quarter of 2012, the Company borrowed and fully-repaid a total of $10.0 million on its credit facility.

Subject to the Company’s financial condition, the amount of funds generated from operations and the level of capital expenditures, the Company’s current intention is to continue to pay quarterly dividends to holders of its common stock. On March 20, 2012, the Board of Directors declared a cash dividend of $0.24 per common share payable to shareholders of record on May 1, 2012. That dividend is payable on May 15, 2012. The Company estimates its total capital expenditures for the remainder of 2012 will be between $90.0 million and $100.0 million. Capital expenditures for the remainder of 2012 are expected to include costs associated with expansion of the Company’s distribution infrastructure, the construction of the resin-coating and sand processing facilities in Marshfield, Wisconsin, and the construction of the new manufacturing facility in the Millen, Georgia area.

The Company maintains an unsecured line of credit with Wells Fargo Bank, N.A. On March 5, 2012, the Company entered into a first amendment to its credit facility to (i) extend its maturity date from January 29, 2013 to July 29, 2013, (ii) increase the size from $10.0 million to $25.0 million and (iii) make other administrative changes to certain covenants and provisions. As of March 31, 2012, there was no outstanding debt under the credit agreement. The Company anticipates that cash on hand, cash provided by operating activities and funds available under its line of credit will be sufficient to meet planned operating expenses, tax obligations, capital expenditures and other cash needs for the next 12 months. Based on these assumptions, the Company believes that its fixed costs could be met even with a moderate decrease in demand for the Company’s products.

Off-Balance Sheet Arrangements

The Company had no off-balance sheet arrangements as of March 31, 2012.

Forward-Looking Information

The statements in this Form 10-Q that are not historical statements, including statements regarding our future financial and operating performance and liquidity and capital resources, are forward-looking statements within the meaning of the federal securities laws. All forward-looking statements are based on management’s current expectations and estimates, which involve risks and uncertainties that could cause actual results to differ materially from those expressed in forward-looking statements. Among these factors are:

• changes in overall economic conditions,

• changes in the cost of raw materials and natural gas used in manufacturing our products,

• changes in demand and prices charged for our products,

• changes in the demand for, or price of, oil and natural gas,

• risks of increased competition,

• technological, manufacturing and product development risks,

• loss of key customers,

• changes in foreign and domestic government regulations, including environmental restrictions on operations and regulation of hydraulic fracturing,

• changes in foreign and domestic political and legislative risks,

• the risks of war and international and domestic terrorism,

• risks associated with foreign operations and foreign currency exchange rates and controls, and

• weather-related risks and other risks and uncertainties.

Additional factors that could affect our future results or events are described from time to time in our reports filed with the Securities and Exchange Commission (the “SEC”). See in particular our annual report on Form 10-K for the fiscal year ended December 31, 2011 under the caption “Risk Factors” and similar disclosures in subsequently filed reports with the SEC. We assume no obligation to update forward-looking statements, except as required by law.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company’s major market risk exposure is to foreign currency fluctuations that could impact its investments in China and Russia. As of March 31, 2012, the Company’s net investment that is subject to foreign currency fluctuations totaled $91.4 million and the Company has recorded a cumulative foreign currency translation loss of $0.7 million, net of deferred income tax benefit. This cumulative translation loss is included in Accumulated Other Comprehensive Loss. From time to time, the Company may enter into forward foreign exchange contracts to hedge the impact of foreign currency fluctuations. There were no such foreign exchange contracts outstanding at March 31, 2012.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934 (the “Exchange Act”) is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports filed under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

As of March 31, 2012, management carried out an evaluation, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. There are inherent limitations to the effectiveness of any

13

system of disclosure controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurances of achieving their control objectives. Based upon and as of the date of that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and to ensure that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting during the quarter ended March 31, 2012 that materially affected, or are reasonably likely to materially affect, those controls.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

On August 4, 2011, CARBO Ceramics Inc. was named as a defendant in a civil lawsuit filed by C-E Minerals, Inc. (“C-E”) in the United States District Court for the Northern District of Georgia, Atlanta Division. C-E alleged that a mutual non-competition provision contained in a Raw Material Requirements Agreement between C-E and CARBO Ceramics Inc., dated June 1, 2003, is invalid under federal antitrust law and applicable state law. The covenant generally prohibits C-E from engaging in the manufacture or sale of ceramic proppant, and prohibits the Company from engaging in the business of selling calcined clay through the end of 2013 (three years after the termination date of the agreement). C-E sought a declaratory judgment that the covenant is invalid, along with a preliminary and permanent injunction that would prevent the enforcement of the covenant. C-E is also sought to recover its attorney’s fees from the Company. C-E subsequently amended its complaint on September 15, 2011 to further allege that the Company has certain monopoly power and has asked for declaratory and injunctive relief that would prevent the Company from enforcing certain damages provisions in its sales contracts. In addition, the Company filed a counter-claim against C-E seeking injunctive relief and damages in connection with sales of ceramic proppant by C-E and its affiliates. C-E filed a motion for a preliminary injunction to prohibit the enforcement of the non-competition provision. The Court held a hearing on this motion on February 15, 2012 and granted a preliminary injunction in favor of C-E on March 13, 2012. The Company and C-E subsequently entered into a settlement agreement by which both parties agreed not to enforce the covenant against the other, and resolved the claims asserted in the lawsuit. As a result, the lawsuit has been dismissed.

On February 9, 2012, the Company, Gary A. Kolstad and Ernesto Bautista III, were named as defendants in a purported class-action lawsuit filed in the United States District Court for the Southern District of New York (the “February SDNY Lawsuit”), brought on behalf of shareholders who purchased the Company’s Common Stock between October 27, 2011 and January 26, 2012 (the “Relevant Time Period”). The suit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of investors who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”). On April 19, 2012, a third purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of Texas, which was also brought on behalf of shareholders who purchased the Company’s Common Stock during the Relevant Time Period (the “April SDTX Lawsuit” and collectively with the April SDNY Lawsuit and the February SDNY Lawsuit, the “Federal Securities Lawsuits”). The April SDNY Lawsuit and the April SDTX Lawsuit allege substantially similar claims as the February SDNY Lawsuit and request unspecified damages and costs.

On March 1, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “Harris County Lawsuit”). The suit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit. The derivative lawsuit requests unspecified damages and costs. The parties to this lawsuit have entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuits.

While each of the Federal Securities Lawsuits and the Harris Country Lawsuit are in their preliminary stages, the Company does not believe they have merit, and plans to vigorously contest and defend against them.

Additionally, from time to time, the Company is the subject of legal proceedings arising in the ordinary course of business. The Company does not believe that any of these proceedings will have a material effect on its business or its results of operations.

The Company cannot predict the ultimate outcome or duration of any lawsuit described in this report.

EX-10.1

Exhibit 10.1

CARBO CERAMICS INC.

CHANGE IN CONTROL SEVERANCE AGREEMENT

CHANGE IN CONTROL SEVERANCE AGREEMENT (the “Agreement”), made and entered into as of [—] (the “Effective Date”), by and between CARBO Ceramics Inc., a Delaware corporation (the “Company”), and [—] (the “Executive”).

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that it is in the best interests of the Company and its stockholders to reinforce and encourage the continued attention and dedication of the Executive to the Company, notwithstanding the possibility or occurrence of a Change in Control (as defined below), by diminishing the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a potential or pending Change in Control;

NOW THEREFORE, in consideration of the premises and the mutual covenants hereinafter set forth, the parties hereto hereby agree as follows:

SECTION 1. Definitions.

As used in this Agreement, capitalized terms shall have the meanings set forth in this Agreement. The following capitalized terms shall have the following meanings:

“Cause” means (i) any material violation by the Executive of any Company policy; (ii) any failure by the Executive substantially to perform his or her duties for the Company; (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 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 Executive’s employment with the Company may not be terminated for Cause unless a majority 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 or her employment for Cause.

“Change in Control” means (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”); (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); (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 or she were a member of the Incumbent Board; (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.

“Change in Control Period” means the period beginning on the date on which a Change in Control occurs and ending on the one-year anniversary thereof.

“Code” means the Internal Revenue Code of 1986, as amended.

“Good Reason” means, without the Executive’s express written consent, the occurrence of any one or more of the following: (i) the assignment of the Executive to duties materially inconsistent with the Executive’s authorities, duties, responsibilities and status (including offices, titles, and reporting requirements) as an officer of the Company, or other changes in the Executive’s authorities, duties or responsibilities, if such assignment or changes result in a material diminution in the Executive’s authorities, duties, or responsibilities from those in effect immediately prior to the Change in Control, including a failure to reelect the Executive to, or a removal of him or her from, any office of the Company that the Executive held immediately prior to the Change in Control; (ii) the Company’s requiring the Executive to be based at a location more than 50 miles from Houston, Texas (except for required travel on the Company’s business to an extent substantially consistent with the Executive’s business obligations immediately prior to the Change in Control) if such action constitutes a material change in the geographic location where the Executive must perform services; (iii) the Company materially breaches this Agreement or any other written agreement with the Executive under which the Executive provides services to the Company; or (iv) a material reduction in the Executive’s base compensation as of the date of the Change in Control; provided, in each case, that within thirty (30) days following the occurrence of any of the events set forth herein, the Executive shall have delivered written notice to the Company of his or her intention to terminate his or her

2

employment for Good Reason, which notice specifies in reasonable detail the circumstances claimed to give rise to the Executive’s right to terminate employment for Good Reason, the Company shall not have cured such circumstances within thirty (30) days following the Company’s receipt of such notice, and the Executive’s Separation from Service with the Company shall have occurred within sixty (60) days following such failure to cure.

“Incentive Bonus” means the annual cash incentive bonus paid to the Executive by the Company, whether pursuant to the Company’s Annual Incentive Arrangement or otherwise.

“Termination Date” means the date on which the Executive experiences a Separation from Service.

SECTION 2. Change in Control Severance Benefits.

2.1. Benefits Upon a Change in Control. If a Change in Control occurs and, during the Change in Control Period: (a) the Company terminates the Executive’s employment with the Company without Cause, or (b) the Executive terminates employment with the Company for Good Reason, and in either case such termination constitutes a Separation from Service, then the Executive (or the Executive’s estate or any beneficiary previously designated by the Executive in writing (a “ Designated Beneficiary”)), if the Executive should die during the period in which payments are being made pursuant to this Section 2.1) shall become entitled to the payment of the benefits as provided below:

(a) Accrued Obligations. Within thirty (30) days after the Termination Date, the Company shall pay to the Executive his or her 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 (determined in accordance with the Company’s standard expense reimbursement policy and practices) (collectively, the “Accrued Benefits”), if any, all as of such Termination Date.

(b) Severance Payment. The Company shall pay to the Executive an amount equal to the sum of (i) the Executive’s Incentive Bonus with respect to the fiscal year immediately preceding the fiscal year in which such Separation from Service takes place 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 (ii) two times (2x) the Executive’s base salary (at the level in effect immediately preceding such Separation from Service) (together, the “Severance Payment”) as follows: (x) within two and one half (2  ¹/2) months following the Separation from Service, a lump sum equal to the lesser of (A) the Severance Payment or (B) the amount described in Section 1.409A-1(b)(9)(iii)(A) of the Treasury Regulations (as

3

amended) promulgated under the Code for the year in which the Separation from Service occurs and (y) 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 (A) the six (6)-month anniversary of Executive’s Termination Date or (B) the Executive’s death. The Executive (or his or her 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 purpose.

2.2. Section 409A. It is intended that this Agreement shall comply with the provisions of Section 409A of the Code and the Treasury Regulations relating thereto so as not to subject the Executive to the payment of additional taxes and interest under Section 409A of the Code. In furtherance of this intent, this Agreement shall be interpreted, operated, and administered in a manner consistent with these intentions.

SECTION 3. Miscellaneous.

3.1. Except as otherwise provided herein or by law, no right or interest of the Executive under this Agreement shall be assignable or transferable, in whole or in part, either directly or by operation of law or otherwise, including without limitation by execution, levy, garnishment, attachment, pledge or in any manner; no attempted assignment or transfer thereof shall be effective; and no right or interest of the Executive under this Agreement shall be liable for, or subject to, any obligation or liability of such Executive.

3.2. This Agreement shall inure to the benefit of and be binding upon the heirs, executors, administrators, successors and assigns of the parties, including any successor to the Company.

3.3.

Description of Modification to

Annual Non-Employee Director Stock Grants

In March 2012, the Compensation Committee of the Board of Directors of CARBO Ceramics Inc.

Stock Based Compensation

5. Stock Based Compensation

The CARBO Ceramics Inc. Omnibus Incentive Plan (the “Omnibus Incentive Plan”) provides for granting of cash-based awards, stock options (both non-qualified and incentive) and other equity-based awards (including stock appreciation rights, phantom stock, restricted stock, restricted stock units, performance shares, deferred share units or share-denominated performance units) to employees and non-employee directors. The amount paid under the Omnibus Incentive Plan to any single participant in any calendar year with respect to any cash-based award shall not exceed $2,000. Awards may be granted with respect to a number of shares of the Company’s Common Stock that in the aggregate does not exceed 750,000 shares prior to the fifth anniversary of its effective date, plus (i) the number of shares that are forfeited, cancelled or returned, and (ii) the number of shares that are withheld from the participants to satisfy an option exercise price or minimum statutory tax withholding obligations. No more than 50,000 shares may be granted to any single participant in any calendar year. Equity-based awards may be subject to performance-based and/or service-based conditions. With respect to stock options and stock appreciation rights granted, the exercise price shall not be less than the market value of the underlying Common Stock on the date of grant. The maximum term of an option is ten years. Restricted stock awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) in equal annual installments over a three-year period but subject to certain limitations, awards may specify other vesting periods. As of March 31, 2012, 568,606 shares were available for issuance under the Omnibus Incentive Plan. Although the Company’s previous stock option plan has expired, outstanding options granted under the plan remain outstanding in accordance with their terms.

As of March 31, 2012, all compensation cost related to stock options granted under the expired stock option plan has been recognized. There were no stock options exercised during the three months ended March 31, 2012. The weighted-average remaining contractual term of the 2,425 options outstanding at March 31, 2012 was approximately 6 months.

A summary of restricted stock activity and related information for the three months ended March 31, 2012 is presented below:

	Shares			Weighted- Average Grant-Date Fair Value
Nonvested at January 1, 2012		129,082		$	75.00
Granted		55,652		$	119.22
Vested		(58,461	)	$	66.15
Forfeited		(1,061	)	$	108.28
Nonvested at March 31, 2012		125,212		$	98.51

As of March 31, 2012, there was $9,322 of total unrecognized compensation cost, net of estimated forfeitures, related to restricted shares granted under the Omnibus Incentive Plan. That cost is expected to be recognized over a weighted-average period of 1.9 years. The total fair value of shares vested during the three months ended March 31, 2012 was $3,867.

The Company has made phantom stock awards to key international employees pursuant to the Omnibus Incentive Plan. The units subject to an award vest and cease to be forfeitable in equal annual installments over a three-year period. Participants awarded units of phantom shares are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the vesting date. In no event will Common Stock of the Company be issued with regard to outstanding phantom shares. As of March 31, 2012, there were 10,105 units of phantom shares granted under the Omnibus Incentive Plan, of which 3,429 have vested and 1,076 have been forfeited, with a total value of $591, a portion of which is accrued as a liability within Other Accrued Expenses.

Legal Proceedings

9. Legal Proceedings

The Company is subject to legal proceedings, claims and litigation arising in the ordinary course of business. While the outcome of these matters is currently not determinable, management does not expect that the ultimate costs to resolve these matters will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows.

On August 4, 2011, CARBO Ceramics Inc. was named as a defendant in a civil lawsuit filed by C-E Minerals, Inc. (“C-E”) in the United States District Court for the Northern District of Georgia, Atlanta Division. C-E alleged that a mutual non-competition provision contained in a Raw Material Requirements Agreement between C-E and CARBO Ceramics Inc., dated June 1, 2003, was invalid under federal antitrust law and applicable state law. On March 13, 2012, the Court granted a preliminary injunction in favor of C-E. The Company and C-E subsequently entered into a settlement agreement by which both parties agreed not to enforce the covenant against the other, and resolved the claims asserted in the lawsuit. As a result, the lawsuit has been dismissed. There was no material impact to the financial statements as a result of this lawsuit.

On February 9, 2012, the Company and two of its officers, Gary A. Kolstad and Ernesto Bautista III, were named as defendants in a purported class-action lawsuit filed in the United States District Court for the Southern District of New York (the “February SDNY Lawsuit”), brought on behalf of shareholders who purchased the Company’s Common Stock between October 27, 2011 and January 26, 2012 (the “Relevant Time Period”). The suit alleges violations of the federal securities laws arising from statements concerning the Company’s business operations and business prospects that were made during the Relevant Time Period and requests unspecified damages and costs. On April 10, 2012, a second purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of New York, brought on behalf of shareholders who purchased or sold CARBO Ceramics Inc. option contracts during the Relevant Time Period (the “April SDNY Lawsuit”). On April 19, 2012, a third purported class-action lawsuit was filed against the same defendants in the United States District Court for the Southern District of Texas, which was also brought on behalf of shareholders who purchased the Company’s Common Stock during the Relevant Time Period (the “April SDTX Lawsuit” and collectively with the April SDNY Lawsuit and the February SDNY Lawsuit, the “Federal Securities Lawsuits”). The April SDNY Lawsuit and the April SDTX Lawsuit allege substantially similar claims as the February SDNY Lawsuit and request unspecified damages and costs.

On March 1, 2012, the Directors of the Company and Mr. Bautista were named as defendants in a purported derivative action lawsuit brought on behalf of the Company by a stockholder in District Court in Harris County, Texas (the “Harris County Lawsuit”). The suit alleges various breaches of fiduciary duty and other duties by the defendants that generally are related to the February SDNY Lawsuit. The derivative lawsuit requests unspecified damages and costs. The parties to this lawsuit have entered into an agreement to stay further proceedings pending the outcome of a motion to dismiss the Federal Securities Lawsuits.

While each of the Federal Securities Lawsuits and the Harris Country Lawsuit are in their preliminary stages, the Company does not believe they have merit, and plans to vigorously contest and defend against them.

The Company cannot predict the ultimate outcome or duration of these lawsuits.

The guidance is effective for the Company beginning in the first quarter of fiscal 2012. The Company adopted this guidance as of January 1, 2012. The adoption did not have a material impact on the Company’s financial position, results of operations or cash flows.
