All shareholders are urged to attend. A formal Notice of the Annual Meeting, Proxy Statement, and Proxy Card accompany this Annual Report and Form 10-K. TO OUR SHAREHOLDERS: During 2013, our operations continued to provide strong cash flows resulting in further improvements to our balance sheet and liquidity. We continued to pay down our debt and reinvest in our operations and, in the first quarter 2014, declared and paid a quarterly cash dividend of $0.125 (12.5 cents) per share. Our net income decreased $1.6 million in 2013, or 9.9%, compared to 2012, and diluted net income per share decreased $0.21, or 7.3%, to $2.66 from $2.87 in 2012. Gross profit from our Lime and Limestone Operations decreased $1.6 million, primarily due to decreased revenues during the year and increased costs of revenues and decreased sales volumes in the fourth quarter 2013 due to the inclement weather conditions. Gross profit from our Natural Gas Interests decreased $1.1 million, resulting principally from decreased production of natural gas and natural gas liquids compared to 2012. Highlights and challenges during 2013 included: Lime and Limestone Operations (cid:127) Revenues decreased $3.4 million, or 2.6%, in 2013 compared to 2012 due to decreased sales volumes of our lime and limestone products, partially offset by a slight increase in prices realized for our products (cid:127) Our diverse customer base continued to serve us well as increased demand from our construction and environmental customers partially offset the decrease in demand from our steel customers Natural Gas Interests (cid:127) Production volumes decreased to 1.0 BCF in 2013 from 1.2 BCF in 2012 due to the normal declines in production from existing wells (cid:127) Due to the increase in prices for natural gas in 2013, our average price per MCF increased slightly to $5.86 compared to $5.74 for 2012 In order to increase profitability in our Lime and Limestone Operations in the face of our increased costs of revenues, we must improve our revenues and control our operational and transportation costs. To improve our lime and limestone revenues, we are seeking to maintain, and increase where possible, both sales volume and prices for our products, which is a challenging task during difficult economic conditions. In addition, we continue to explore ways to improve and expand our operations and production capacity through major development projects and acquisitions as conditions warrant or opportunities arise. Even with the normal declines in production rates from our existing wells, we expect our Natural Gas Interests to continue to make a positive contribution to our cash flows and results of operations. We are grateful for the continued support of our dedicated employees and our loyal customers and shareholders. We remain committed to improving the performance of our Company and further enhancing shareholder value and believe that we are well positioned both operationally and financially to take advantage of increased opportunities as the economy continues to improve. 23MAR201221180229 Timothy W.

(the ‘‘Company,’’ the ‘‘Registrant,’’ ‘‘We’’ or ‘‘Our’’), which was incorporated in 1950, conducts its business through two segments, Lime and Limestone Operations and Natural Gas Interests. The Company’s principal corporate office is located at 5429 LBJ Freeway, Suite 230, Dallas, Texas 75240. The Company’s telephone number is (972) 991-8400, and its internet address is www.uslm.com. The Company’s annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the ‘‘Exchange Act’’), as well as the Company’s definitive proxy statement filed pursuant to Section 14(a) of the Exchange Act, are available free of charge on the Company’s website as soon as reasonably practicable after the Company electronically files such material with, or furnishes it to, the Securities and Exchange Commission (the ‘‘SEC’’). Lime and Limestone Operations. Business and Products. The Company, through its Lime and Limestone Operations, is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), oil and gas services, industrial (including paper and glass manufacturers), roof shingle and agriculture (including poultry and cattle feed producers) industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company—Shreveport, U.S. Lime Company—St. Clair and U.S. Lime Company—Transportation. The Company extracts high-quality limestone from its open-pit quarries and an underground mine and then processes it for sale as pulverized limestone, quicklime, hydrated lime and lime slurry. Pulverized limestone (also referred to as ground calcium carbonate) (‘‘PLS’’) is produced by applying heat to dry the limestone, which is then ground to granular and finer sizes. Quicklime (calcium oxide) is produced by heating limestone to very high temperatures in kilns in a process called calcination. Hydrated lime (calcium hydroxide) is produced by reacting quicklime with water in a controlled process. Lime slurry (milk of lime) is a suspended solution of calcium hydroxide produced by mixing quicklime with water in a lime slaker. PLS is used in the production of construction materials such as roof shingles and asphalt paving, as an additive to agriculture feeds, in the production of glass, as a soil enhancement, in flue gas treatment for utilities and other industries requiring scrubbing of emissions for environmental purposes and for mine safety dust in coal mining operations. Quicklime is used primarily in metal processing, in flue gas treatment, in soil stabilization for highway, road and building construction, as well as for oilfield roads and drill sites, in the manufacturing of paper products and in sanitation and water treatment systems. Hydrated lime is used primarily in municipal sanitation and water treatment, in soil stabilization for highway, road and building construction, in flue gas treatment, in asphalt as an anti-stripping agent, as a conditioning agent for oil and gas drilling mud, in the production of chemicals and in the production of construction materials such as stucco, plaster and mortar. Lime slurry is used primarily in soil stabilization for highway, road and building construction. 1 Product Sales. In 2013, the Company sold almost all of its lime and limestone products in the states of Arizona, Arkansas, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, Oklahoma, Pennsylvania, Tennessee, and Texas. Sales were made primarily by the Company’s eight sales employees who call on current and potential customers and solicit orders, which are generally made on a purchase-order basis. The Company also receives orders in response to bids that it prepares and submits to current and potential customers. Principal customers for the Company’s lime and limestone products are construction customers (including highway, road and building contractors), metals producers (including steel producers), environmental customers (including municipal sanitation and water treatment facilities and flue gas treatment), oil and gas services companies, industrial customers (including paper manufacturers and glass manufacturers), roof shingle manufacturers and poultry and cattle feed producers. During 2013, the strongest demand for the Company’s lime and limestone products was from construction customers, industrial customers, environmental customers, metals producers, oil and gas services companies and roof shingle manufacturers. Approximately 650 customers accounted for the Company’s sales of lime and limestone products during 2013. No single customer accounted for more than 10% of such sales. The Company is generally not subject to significant customer demand and credit risks as its customers are considerably diversified as to geographic location and industrial concentration. However, given the nature of the lime and limestone industry, the Company’s profits are very sensitive to changes in sales volume and prices. Lime and limestone products are transported by truck and rail to customers generally within a radius of 400 miles of each of the Company’s plants. All of the Company’s 2013 sales were made within the United States. Order Backlog. The Company does not believe that backlog information accurately reflects anticipated annual revenues or profitability from year to year. Seasonality. The Company’s sales have typically reflected seasonal trends, with the largest percentage of total annual shipments and revenues normally being realized in the second and third quarters. Lower seasonal demand normally results in reduced shipments and revenues in the first and fourth quarters. Inclement weather conditions generally have a negative impact on the demand for lime and limestone products supplied to construction-related customers, as well as on the Company’s open-pit quarrying operations. Limestone Reserves. The Company’s limestone reserves contain at least 96% calcium carbonate (CaCO3). The Company has two subsidiaries that extract limestone from open-pit quarries: Texas Lime Company (‘‘Texas Lime’’), which is located near Cleburne, Texas, and Arkansas Lime Company (‘‘Arkansas Lime’’), which is located near Batesville, Arkansas. U.S. Lime Company—St. Clair (‘‘St. Clair’’) extracts limestone from an underground mine located near Marble City, Oklahoma. Colorado Lime Company (‘‘Colorado Lime’’) owns property containing limestone deposits at Monarch Pass, located 15 miles west of Salida, Colorado. Existing crushed stone stockpiles on the property are being used to provide feedstock to the Company’s plants in Salida and Delta, Colorado. Access to all properties is provided by paved roads and, in the case of Arkansas Lime and St. Clair, also by rail. Texas Lime operates a quarry, located on approximately 3,200 acres of land that contains known high-quality limestone reserves in a bed averaging 28 feet in thickness, with an overburden that ranges from 0 to 50 feet. Texas Lime also has mineral interests in approximately 560 acres of land adjacent to the northwest boundary of its property. The reserves, as of December 31, 2013, were approximately 21 million tons of proven recoverable reserves plus approximately 80 million tons of probable recoverable reserves. Assuming the current level of production and recovery rate is maintained, the Company estimates that these reserves are sufficient to sustain operations for more than 75 years. 2 Arkansas Lime operates two quarries and has hydrated lime and limestone production facilities on a second site linked to the quarries by its own standard-gauge railroad. The quarries cover approximately 1,050 acres of land located in Independence County, Arkansas containing a known deposit of high-quality limestone reserves (the ‘‘Batesville Quarry’’). The average thickness of the high-quality limestone bed is approximately 60 feet, with an average overburden thickness of approximately 30 feet. The aggregate reserves for the Batesville Quarry, as of December 31, 2013, were approximately 16 million tons of proven recoverable reserves. In 2005, the Company acquired approximately 2,500 acres of land in nearby Izard County, Arkansas (the ‘‘North Quarry’’). The high-quality reserves on these 2,500 acres, as of December 31, 2013, were approximately 76 million tons of probable recoverable reserves. The Company is assessing the costs required to improve the transportation infrastructure between the North Quarry and Arkansas Lime’s production facilities and other development costs to prepare the North Quarry for mining. Assuming the current level of production and recovery rate is maintained, the Company estimates that its total reserves in Arkansas are sufficient to sustain operations for more than 65 years. St. Clair, acquired by the Company in December 2005, operates an underground mine located on approximately 500 acres it owns containing high-quality limestone reserves. The reserves, as of December 31, 2013, were approximately 13 million tons of probable recoverable reserves on the 500 acres. Assuming the current level of production and recovery rate is maintained, the Company estimates that the probable recoverable reserves are sufficient to sustain operations for more than 25 years. In addition, St. Clair also has the right to mine the high-quality limestone contained in approximately 1,500 adjacent acres pursuant to long-term mineral leases. Although limestone is being mined from a portion of the leased properties, the Company has not conducted a drilling program to identify and categorize reserves on the 1,500 leased acres. During 2013, the Company produced an aggregate of approximately 3 million tons of limestone from its quarries and mine. Colorado Lime acquired the Monarch Pass Quarry in November 1995 and has not carried out any mining on the property. A review of the potential limestone resources has been completed by independent geologists; however, the Company has not initiated a drilling program. Consequently, it is not possible to identify and categorize reserves. The Monarch Pass Quarry, which had been operated for many years until the early 1990s, contains a mixture of limestone types, including high-quality calcium limestone and dolomite. Assuming the current level of production is maintained, the Company estimates that the remaining crushed stone stockpiles on the property are sufficient to supply its plants in Salida and Delta, Colorado for approximately 15 years. Quarrying and Mining. The Company extracts limestone by the open-pit method at its Texas and Arkansas quarries. The Monarch Pass Quarry is also an open-pit quarry, but is not being mined at this time. The open-pit method consists of removing any overburden comprising soil, trees and other substances, including inferior limestone, and then extracting the exposed high-quality limestone. The Company removes such overburden by utilizing both its own employees and equipment and those of outside contractors. Open-pit mining is generally less expensive than underground mining. The principal disadvantage of the open-pit method is that operations are subject to inclement weather and overburden removal. The limestone is extracted by drilling and blasting, utilizing standard mining equipment. At its St. Clair underground mine, the Company mines limestone using room and pillar mining. The Company has no knowledge of any recent changes in the physical quarrying or mining conditions on any of its properties that have materially affected its quarrying or mining operations, and no such changes are anticipated. Plants and Facilities. After extraction, limestone is crushed and screened and, in the case of PLS, ground and dried, or, in the case of quicklime, processed in kilns. Quicklime may then be further processed in hydrators and slakers to produce hydrated lime and lime slurry. The Company processes 3 and distributes lime and/or limestone products at five plants, four lime slurry facilities and one terminal facility in Shreveport, Louisiana. All of its plants and facilities are accessible by paved roads, and, in the case of the Arkansas Lime and St. Clair plants and the Shreveport terminal, also by rail. The Texas Lime plant has an annual capacity of approximately 470 thousand tons of quicklime from two preheater rotary kilns. The plant also has PLS equipment, which, depending on the product mix, has the capacity to produce approximately 800 thousand tons of PLS annually. The Arkansas plant is situated at the Batesville Quarry. Utilizing three preheater rotary kilns, this plant has an annual capacity of approximately 630 thousand tons of quicklime. Arkansas Lime’s PLS and hydrating facilities are situated on a tract of 290 acres located approximately two miles from the Quarry, to which it is connected by a Company-owned, standard-gauge railroad. The PLS equipment, depending on the product mix, has the capacity to produce approximately 300 thousand tons of PLS annually. The St. Clair plant has an annual capacity of approximately 180 thousand tons of quicklime from two rotary kilns, one of which is not a preheater kiln. The plant also has PLS equipment, which has the capacity to produce approximately 150 thousand tons of PLS annually. In the fourth quarter 2013, the Company received the necessary air permit from the Oklahoma Department of Environmental Quality to replace the non-preheater kiln with the construction of a new highly efficient vertical heat regenerative kiln. The Company plans to assess the economics and market demand before making a decision regarding the modernization of the St. Clair plant. The Company also maintains lime hydrating and bagging equipment at the Texas, Arkansas and St. Clair plants. Storage facilities for lime and limestone products at each plant consist primarily of cylindrical tanks, which are considered by the Company to be adequate to protect its lime and limestone products and to provide an available supply for customers’ needs at the expected volumes of shipments. Equipment is maintained at each plant to load trucks and, at the Arkansas Lime and St. Clair plants, to load railroad cars. Colorado Lime operates a limestone grinding and bagging facility with an annual capacity of approximately 125 thousand tons, located on approximately three and one-half acres of land in Delta, Colorado, and a limestone drying, grinding and bagging facility, with an annual capacity of approximately 40 thousand tons, located on eight acres of land in Salida, Colorado. The Salida property is leased from the Union Pacific Railroad for a five-year term ending June 2014, with a five-year renewable option. During 2013, the Company’s utilization rate was approximately 57% of its aggregate approximate annual production capacity for the plants in its Lime and Limestone Operations. U.S. Lime Company uses quicklime to produce lime slurry and has one facility to serve the Greater Houston area construction market and three facilities to serve the Dallas-Ft. Worth Metroplex. The Company established U.S. Lime Company—Transportation primarily to deliver lime slurry produced by U.S. Lime Company to customers in the Dallas-Ft. Worth Metroplex. U.S. Lime Company—Shreveport operates a distribution terminal in Shreveport, Louisiana, which is connected to a railroad, to provide lime storage, hydrating, slurrying and distribution capacity to service markets in Louisiana and East Texas. The Company believes that its plants and facilities are adequately maintained and insured. Employees. At December 31, 2013, the Company employed 297 persons, 35 of whom were engaged in administrative and management activities, and eight of whom were engaged in sales activities. Of the Company’s 254 production employees, 116 are covered by two collective bargaining agreements. The agreement for the Texas facility expires in November 2014, and the agreement for the Arkansas facility expires in January 2017. The Company believes that its employee relations are good. 4 Competition. The lime industry is highly regionalized and competitive, with quality, price, ability to meet customer demands and specifications, proximity to customers, personal relationships and timeliness of deliveries being the prime competitive factors. The Company’s competitors are predominantly private companies. The lime industry is characterized by high barriers to entry, including: the scarcity of high-quality limestone deposits on which the required zoning and permits for extraction can be obtained; the need for lime plants and facilities to be located close to markets, paved roads and railroad networks to enable cost-effective production and distribution; clean air and anti-pollution regulations, including those related to greenhouse gas emissions, which make it more difficult to obtain permitting for new sources of emissions, such as lime kilns; and the high capital cost of the plants and facilities. These considerations reinforce the premium value of operations having permitted, long-term, high-quality limestone reserves and good locations and transportation relative to markets. Lime producers tend to be concentrated on known limestone formations where competition takes place principally on a regional basis. The industry as a whole has expanded its customer base and, while the steel industry and environmental-related users, including utility plants, are the largest market sectors, it also counts chemical users and other industrial users, including paper manufacturers and highway, road and building contractors, among its major customers. Consolidation in the lime industry has left the three largest companies accounting for more than two-thirds of North American production capacity. In addition to the consolidations, and often in conjunction with them, many lime producers have undergone modernization and expansion projects to upgrade their processing equipment in an effort to improve operating efficiency. The Company’s Texas and Arkansas modernization and expansion projects, its acquisitions of the St. Clair operations in Oklahoma and the lime slurry operations in Texas, and its development projects in Arkansas should allow the Company to continue to remain competitive, protect its markets and position itself for the future. In addition, the Company will continue to evaluate internal and external opportunities for expansion and growth, as conditions warrant or opportunities arise. The Company may have to revise its strategy or otherwise find ways to enhance the value of the Company, including entering into strategic partnerships, mergers or other transactions. Impact of Environmental Laws. The Company owns or controls large areas of land, upon which it operates limestone quarries, an underground mine, lime plants and other facilities with inherent environmental responsibilities and environmental compliance costs, including capital, maintenance and operating costs with respect to pollution control facilities, the cost of ongoing monitoring programs, the cost of reclamation and remediation efforts and other similar environmental costs and liabilities. The Company’s operations are subject to various federal, state, and local laws and regulations relating to the environment, health and safety, and other regulatory matters, including the Clear Air Act, the Clean Water Act, the Resource Conservation and Recovery Act and the Comprehensive Environmental Response, Compensation, and Liability Act (‘‘Environmental Laws’’). These Environmental Laws grant the United States Environmental Protection Agency (the ‘‘EPA’’) and state governmental agencies the authority to promulgate regulations that could result in substantial expenditures on pollution control, waste management and permitting and compliance activities. The Company has not been named as a potentially responsible party in any federal superfund cleanup site or state-led cleanup site. The rate of change of Environmental Laws continues to be rapid, and compliance can require significant expenditures. For example, federal legislation required the Company’s plants with operating kilns to apply for Title V operating permits that have significant ongoing compliance monitoring costs. In addition to the Title V permits, other environmental operating permits are required for the Company’s operations, and such permits are subject to modification during the permit renewal process, and to revocation. Raw materials and fuels used to manufacture lime products contain chemicals and 5 compounds, such as trace metals, that may be classified as hazardous substances. In 2004, the EPA adopted new National Ambient Air Quality Standards (‘‘NAAQS’’) for ozone. Pursuant to the 2004 NAAQS, in 2007 the Texas Commission on Environmental Quality (the ‘‘TCEQ’’) adopted regulations to limit emissions of nitrogen oxides (‘‘NOx’’) from industrial operations, including lime kilns, located in the Dallas-Ft. Worth area, which resulted in substantial expenditures on pollution control measures and emissions monitoring systems. In 2008 and 2009, the Company spent a total of approximately $700 thousand on these systems to be in compliance with NAAQS, to which Texas Lime became subject on March 1, 2009. In 2010, the EPA adopted new NAAQS for sulfur dioxide and nitrogen dioxide. If the Company modifies any of its lime plants, the New Source Review (discussed below) permitting process may entail modeling and, potentially, installation of additional emission controls to demonstrate compliance with those new NAAQS. As of January 1, 2010, the EPA required large emitters of greenhouse gases, including the Company’s plants, to collect and report greenhouse gas emissions data. The EPA indicated it will use the data collected through the greenhouse gas reporting rules to decide whether to promulgate future greenhouse gas emission limits or possible taxes. On May 13, 2010, the EPA issued a final rule ‘‘tailoring’’ its New Source Review permitting and Federal Operating Permit programs to apply to facilities with certain thresholds of greenhouse gas emissions. The emission rates are determined based upon the CO2 equivalent (‘‘CO2e’’) of six greenhouse gases. The first phase of the ‘‘Tailoring Rule,’’ known as Step 1, required existing facilities subject to federal New Source Review for pollutants other than greenhouse gases to include greenhouse gases in their permits if greenhouse gas emissions will increase by 75,000 tons or more beginning January 2, 2011. In July 2011, Step 2 of the Tailoring Rule extended New Source Review and Federal Operating permits to new sources that emit or have the potential to emit at least 100,000 tons per year CO2e or existing sources that emit at that level and that undertake modifications that increase emissions by at least 75,000 tons per year CO2e. On June 29, 2012, the EPA issued its final regulation for Step 3 of the Tailoring Rule, whereby it decided to retain the Step 2 applicability thresholds. Thus, any new facilities or major modifications to existing facilities that exceed the federal New Source Review emission thresholds will be required to use ‘‘best available control technology’’ and energy efficiency measures to minimize greenhouse gas emissions. On May 3, 2011, the EPA finalized a partial disapproval of the Texas Prevention of Significant Deterioration State Implementation Program, which established the EPA as the permitting authority for greenhouse gas emitting sources in Texas. In 2013, the Texas legislature passed a law giving the TCEQ the authority to regulate greenhouse gas emissions. On February 4, 2014, the EPA Regional Administrator for Region 6 (which includes Texas) delegated authority for greenhouse permitting to the State of Texas. While this action is subject to a public comment period, it is expected that the delegation will be finalized in the first half of 2014. While there is no pending federal or state rulemaking specifically affecting the lime industry, the EPA may amend its existing regulations or promulgate new regulations in the future. The Company may incur additional costs to comply with future regulatory changes. Although the timing and impact of climate change legislation and of regulations limiting greenhouse gas emissions are uncertain, the consequences of such legislation and regulation are potentially significant for the Company because the production of CO2 is inherent in the manufacture of lime through the calcination of limestone and combustion of fossil fuels. The EPA’s implementation of the Tailoring Rule to New Source Review permitting could result in increased time and costs of plant upgrades and expansions. The passage of climate change legislation, and other regulatory initiatives by the Congress, the states or the EPA that restrict or tax emissions of greenhouse gases, could adversely affect the Company. There is no assurance that changes in the law or regulations will not be adopted, such as the imposition of a carbon tax, a cap-and-trade program requiring the Company to purchase carbon credits, or other measures that would require reductions in emissions or 6 changes to raw materials, fuel use or production rates, that could have a material adverse effect on the Company’s financial condition, results of operations, cash flows and competitive position. In the courts, several cases have been filed and decisions issued that may increase the risk of claims being filed by third parties against companies for their greenhouse gas emissions. Such cases may seek to challenge air permits, to force reductions in greenhouse gas emissions or to recover damages for alleged climate change impacts to the environment, people and property. The Company incurred capital expenditures related to environmental matters of approximately $395 thousand, $428 thousand and $407 thousand in 2013, 2012 and 2011, respectively. The Company’s recurring costs associated with managing and disposing of potentially hazardous substances (such as fuel and lubricants used in operations) and maintaining pollution control equipment amounted to approximately $808 thousand, $852 thousand and $744 thousand in 2013, 2012 and 2011, respectively. The Company recognizes legal reclamation and remediation obligations associated with the retirement of long-lived assets at their fair value at the time the obligations are incurred (‘‘Asset Retirement Obligations’’ or ‘‘AROs’’). Over time, the liability for AROs is recorded at its present value each period through accretion expense, and the capitalized cost is amortized over the useful life of the related asset. Upon settlement of the liability, the Company either settles the ARO for its recorded amount or recognizes a gain or loss. AROs are estimated based on studies and the Company’s process knowledge and estimates, and are discounted using an appropriate interest rate. The AROs are adjusted when further information warrants an adjustment. The Company believes its accrual of $1.3 million for AROs at December 31, 2013 is reasonable. 7 Map of United States Lime & Minerals, Inc. Operations/Interests. 5MAR201414501127 Natural Gas Interests. Interests. The Company, through its wholly owned subsidiary, U.S. Lime Company—O & G, LLC (‘‘U.S. Lime O & G’’), has royalty interests ranging from 15.4% to 20% and a 20% non-operating working interest with respect to oil and gas rights on the Company’s approximately 3,800 acres of land located in Johnson County, Texas, in the Barnett Shale Formation. These interests are derived from the Company’s May 2004 oil and gas lease agreement (the ‘‘O & G Lease’’) with EOG Resources, Inc. (‘‘EOG’’) with respect to oil and gas rights on its Texas Lime property that will continue on currently producing wells so long as EOG is producing natural gas from such wells as set forth in the O & G Lease. During the fourth quarter 2005, drilling of the first natural gas well under the O & G Lease was completed, and natural gas production began in February 2006. The Company’s overall average revenue interest is 34.7% in the 33 wells currently producing under the O & G Lease. A total of 34 wells have been drilled under the O & G Lease, but one of the wells ceased production in 2011 and has been plugged and abandoned. 8 In November 2006, through U.S. Lime O & G, the Company entered into a drillsite and production facility lease agreement and subsurface easement (the ‘‘Drillsite Agreement’’) with XTO Energy Inc. (‘‘XTO’’), which has an oil and gas lease covering approximately 538 acres of land contiguous to the Company’s Johnson County, Texas property. Pursuant to the Drillsite Agreement, the Company receives a 3% royalty interest and a 12.5% working interest, resulting in a 12.4% revenue interest, in the six XTO wells drilled from a padsite located on the Company’s property. U.S. Lime O & G has no direct employees and is not the operator of any wells drilled on the properties subject to either the O & G Lease or the Drillsite Agreement (the ‘‘O & G Properties’’). The only decision that the Company makes is whether to participate as a non-operating working interest owner and pay its proportionate share of drilling, completing, working over and operating a well. Regulation. Many aspects of the development, production, pricing and marketing of natural gas are regulated by federal and state agencies. Legislation affecting the natural gas industry is under constant review for amendment or expansion, which frequently increases the regulatory burden on affected members of the industry. Oil and gas development and production operations are subject to various types of regulation at the federal, state and local levels that may impact the Company’s royalty and non-operating working interests. Such regulation includes: (cid:127) requiring permits for the drilling of wells; (cid:127) numerous federal and state safety requirements; (cid:127) environmental requirements; (cid:127) property taxes and severance taxes; and (cid:127) specific state and federal income tax provisions. The TCEQ has adopted regulations limiting air emissions from oil and natural gas production in the Barnett Shale, where the O & G Properties are located. The EPA has adopted greenhouse gas monitoring and reporting regulations applicable to the petroleum and natural gas industry that require persons that hold state drilling permits that will result in annual greenhouse gas emissions of 25,000 metric tons or more to report annually those emissions from certain sources. The EPA indicated that it will use data collected through the reporting rules to decide whether to promulgate future greenhouse gas emission limits. Future changes to greenhouse gas regulations could affect the relative competitiveness of, and therefore the demand for, natural gas and other fossil fuels. The drilling on the Company’s O & G Properties involves hydraulic fracturing. On April 18, 2012, the EPA issued new final regulations under the New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants. The new regulations are designed to reduce volatile organic compound emissions from hydraulically fractured wells and other equipment associated with oil and gas development. The regulations established a phase-in period that extends until January 2015. During the phase-in period, owners and operators must either flare their emissions or use so-called ‘‘green completion’’ technology. Green completions allow for the recovery of natural gas that would formerly have been vented or flared. After January 2015, all newly hydraulically fractured wells must use green completion technology. Hydraulic fracturing is a technique used to produce natural gas from shale, including the Barnett Shale. Hydraulic fracturing has historically been regulated by state oil and natural gas commissions. However, the EPA has asserted federal regulatory authority over certain hydraulic fracturing activities involving diesel under the Safe Drinking Water Act (‘‘SDWA’’). The EPA has begun the process of drafting guidance documents related to this newly asserted regulatory authority, which could include a 9 broad definition of diesel that would cover a variety of oils that are not diesel but that have similar carbon-chain molecules. The EPA also plans to investigate the treatment of wastewater from hydraulic fracturing for the purpose of setting new standards for discharges from natural gas drilling to publicly owned treatment works. In addition, certain other governmental reviews are either underway or being proposed that focus on environmental aspects of hydraulic fracturing practices, including a four-year study by the EPA expected to be completed later in 2014. These on-going or proposed reviews, depending on their scope and results, could spur initiatives to further regulate hydraulic fracturing under the SDWA or other regulatory programs. Additionally, the Congress, the EPA and various states have proposed or adopted legislation regulating or requiring disclosure regarding hydraulic fracturing in connection with drilling operations. For example, pursuant to legislation adopted by the State of Texas in June 2011, the Texas Railroad Commission enacted a rule in December 2011, requiring disclosure of certain information regarding additives, chemical ingredients, concentrations and water volumes used in hydraulic fracturing. These new laws or regulations could adversely affect the cost of drilling and production from the O & G Properties. Customers and Pricing. The pricing of natural gas sales is primarily determined by supply and demand in the marketplace and can fluctuate considerably. As the Company is not the operator of the wells drilled on the O & G Properties, it has limited access to timely information, involvement and operational control over the volumes of natural gas produced and sold and the terms and conditions, including price, on which such volumes are marketed and sold, all of which is controlled by the operators. Although the Company has the right to take its portion of natural gas production in kind, it currently has elected to have its natural gas production marketed by the operators. The prices that the Company receives for its natural gas production is also affected by the amount of natural gas liquids included in the natural gas and the prices for those liquids. There has been a dramatic decline in prices for natural gas and natural gas liquids in recent years due to increased supply, although prices for natural gas have risen recently due to cold winter weather conditions. Drilling Activity. The Company participated as a royalty interest and non-operating working interest owner in the drilling of eight gross (1.6 net) wells under the O & G Lease in the fourth quarter 2009 and first quarter 2010, five of which were completed as producing wells during the fourth quarter 2010, and three of which were completed as producing wells in late June 2011. All of the wells are located in Johnson County, Texas. No new wells are currently being drilled. The Company cannot predict the number of additional wells that ultimately will be drilled, if any, or their results. Production Activity. The number of gross and net producing wells and production activity for the years ended December 31, 2013, 2012 and 2011 are as follows: Producing wells(1) 2013 2012 2011 Gross Net(2) Gross Net(2) Gross Net(2) O & G Lease . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

(3) Average sales price per MCF includes sales prices of natural gas liquids contained in the natural gas. (4) Includes taxes other than income taxes. Delivery Commitments. There are no delivery commitments for the Company’s natural gas production to which U.S. Lime O & G is a party. Internal Controls Over Reserves Estimates. The Company’s policies regarding internal controls over the recording of reserve estimates require reserves to be in compliance with the SEC definitions and guidance and prepared in accordance with generally accepted petroleum engineering principles. In each of the years 2013, 2012 and 2011, the Company retained DeGolyer and MacNaughton, independent third-party petroleum engineers, to perform appraisals of 100% of its proved reserves in compliance with these standards. Reserves. The following table reflects the proved developed, proved undeveloped and total proved reserves (all of the which are located in Johnson County, Texas), future estimated net revenues and standardized measure at December 31, 2013, 2012 and 2011. The reserves and future estimated net revenues are based on the reports prepared by DeGolyer and MacNaughton. Proved developed reserves included 39, 39 and 39 producing wells at December 31, 2013, 2012 and 2011, respectively. The Company’s proved reserves have not been filed with, or included in, any reports to any federal agency, other than those filed with the SEC. 2013(2) 2012(2) 2011(2) Developed Undeveloped Total Developed Undeveloped Total Developed Undeveloped Total Proved natural gas reserves (BCF) . . . . 7.6 0.0 7.6 8.3 0.0 8.3 10.3 0.0 10.3 Proved natural gas liquids and condensate reserves (MMBBLS) . . . . . .

(2) The reserve estimates as of December 31, 2013, 2012 and 2011 utilized 12-month average pricing, as now required by accounting principles generally accepted in the United States of America, of $3.88, $2.87 and $4.46 per MCF of natural gas and $29.95, $30.27 and $49.58 per BBL of natural gas liquids, respectively. Undeveloped Acreage. Since the Company is not the operator, it has limited information regarding undeveloped acreage and does not know how many acres the operators classify as undeveloped acreage, if any, or the number of wells that ultimately will be drilled on the O & G Properties. Glossary of Certain Oil and Gas Terms. The definitions set forth below shall apply to the indicated terms as used in this Report. All volumes of natural gas referred to herein are stated at the legal pressure base of the state or area where the reserves exist and at 60 degrees Fahrenheit and in most instances are rounded to the nearest major multiple. ‘‘BBL’’ means a standard barrel containing 42 United States gallons. 11 ‘‘BCF’’ means one billion cubic feet under prescribed conditions of pressure and temperature and represents a basic unit for measuring the production of natural gas. ‘‘Depletion’’ means (i) the volume of hydrocarbons extracted from a formation over a given period of time, (ii) the rate of hydrocarbon extraction over a given period of time expressed as a percentage of the reserves existing at the beginning of such period, or (iii) the amount of cost basis at the beginning of a period attributable to the volume of hydrocarbons extracted during such period. ‘‘Formation’’ means a distinct geologic interval, sometimes referred to as the strata, which has characteristics (such as permeability, porosity and hydrocarbon saturations) that distinguish it from surrounding intervals. ‘‘Future estimated net revenues’’ means the result of applying current prices of oil and natural gas to future estimated production from oil and natural gas proved reserves, reduced by future estimated expenditures, based on current costs to be incurred, in developing and producing the proved reserves, excluding overhead. ‘‘MCF’’ means one thousand cubic feet under prescribed conditions of pressure and temperature and represents a basic unit for measuring the production of natural gas. ‘‘MMBBLS’’ means one million BBLS. ‘‘Operator’’ means the individual or company responsible for the exploration, development and production of an oil or natural gas well or lease. ‘‘Proved oil and gas reserves’’ are those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. (i) The area of the reservoir considered as proved includes: (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data. (ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty. (iii) Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty. (iv) Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or 12 program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities. (v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. ‘‘Royalty’’ means an interest in an oil and gas lease that gives the owner of the interest the right to receive a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but generally does not require the owner to pay any portion of the costs of drilling or operating the wells on the leased acreage. ‘‘Severance tax’’ means an amount of tax, surcharge or levy recovered by governmental agencies from the gross proceeds of oil and natural gas sales. Severance tax may be determined as a percentage of proceeds or as a specific amount per volumetric unit of sales. Severance tax is usually withheld from the gross proceeds of oil and natural gas sales by the first purchaser (e.g., pipeline or refinery) of production. ‘‘Standardized measure of discounted future net cash flows’’ (also referred to as ‘‘standardized measure’’) means the value of future estimated net revenues, calculated in accordance with SEC guidelines, to be generated from the production of proved reserves net of estimated production and future development costs, using prices and costs at the date of estimation, without future escalation, and estimated income taxes, and without giving effect to non-property related expenses such as general and administrative expenses, debt service and depreciation, depletion and amortization, and discounted using an annual discount rate of 10%. ‘‘Undeveloped acreage’’ means acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves. ‘‘Working interest’’ means a real property interest entitling the owner to receive a specified percentage of the proceeds of the sale of oil and natural gas production or a percentage of the production, but requires the owner of the working interest to bear the cost to explore for, develop and produce such oil and natural gas. ITEM 1A. RISK FACTORS. General. Both of our business segments continue to be adversely impacted by difficult economic conditions in the U.S. The continuing difficult economic conditions in the United States have reduced demand for our lime and limestone products. While demand from our construction customers, primarily those involved in highway construction, increased during 2013, our steel customers reduced their purchase volumes due to the ongoing difficult economic conditions. Prices for natural gas and natural gas liquids decreased dramatically in recent years due to increased supply, although natural gas prices have risen recently due to cold winter weather conditions. Corresponding to the decrease in natural gas and natural gas liquids prices, drilling activity declined, reducing demand from our oil and gas services customers for our lime and limestone products. 13 For us to maintain or increase our profitability, we must maintain or increase our revenues and improve cash flows and continue to control our operational and selling, general and administrative expenses. If we are unable to maintain our revenues and control our costs in these difficult economic times, our financial condition, results of operations, cash flows and competitive position could be materially adversely affected. We may be adversely affected by any disruption in, or failure of, our information technology systems, including due to cybersecurity risks and incidents. We rely upon the capacity, reliability and security of our information technology (‘‘IT’’) systems for our manufacturing, financial and administrative functions. We also face the challenge of supporting our IT systems and implementing upgrades when necessary. Our IT systems security measures are focused on the prevention, detection and remediation of damage from computer viruses, natural disasters, unauthorized access, cyber attack and other similar disruptions. However, our IT systems may remain vulnerable to damage despite our implementation of security measures that we feel protect our IT systems. Any failure, accident or security breach involving our IT systems could result in disruption to our operations. A material breach in the security of our IT systems could negatively impact our manufacturing operations or financial and administrative functions, or result in the compromise of personal information of our employees, customers or suppliers. To the extent any such failure, accident or security breach results in disruption to our operations, loss or disclosure of, or damage to, our data or confidential information, our reputation, business, results of operations and financial condition could be materially adversely affected. Lime and Limestone Operations. In the normal course of our Lime and Limestone Operations, we face various business and financial risks that could have a material adverse effect on our financial position, results of operations, cash flows and competitive position. Not all risks are foreseeable or within our ability to control. These risks arise from various factors, including, but not limited to, fluctuating demand for our lime and limestone products, including as a result of downturns in the economy and construction, housing and steel industries, changes in legislation and regulations, including Environmental Laws, health and safety regulations and requirements to renew or obtain operating permits, our ability to produce and store quantities of lime and limestone products sufficient in amount and quality to meet customer demands and specifications, the success of our modernization, expansion and development strategies, including our ability to sell our increased lime capacity at acceptable prices, our ability to execute our strategies and complete projects on time and within budget, our ability to integrate, refurbish and/or improve acquired facilities, our access to capital, increasing costs, especially fuel, electricity, transportation and freight costs, inclement weather and the effects of seasonal trends. We receive a portion of our coal and petroleum coke by rail, so the availability of sufficient solid fuels to run our plants could be diminished significantly in the event of major rail disruptions. Domestic coal and petroleum coke are also being exported, increasing competition and prices for the domestic supply. In addition, our freight costs to deliver our lime and limestone products are high relative to the value of our products and have increased significantly in recent years. Our costs for delivery of solid fuels, as well as our products, also increase as demand for rail and trucking by other industries and new Department of Transportation rules regarding hours of service for drivers reduce the availability of rail cars and trucks to deliver solid fuels to our plants and deliver our products to our customers. If we are unable to continue to pass along our increasing coal, petroleum coke, diesel, natural gas, electricity, transportation and freight costs to our customers, our financial condition, results of operations, cash flows and competitive position could be materially adversely affected. 14 We quote on a delivered price basis to certain customers, which requires us to estimate future delivery costs. Our actual delivery costs may exceed these estimates, which would reduce our profitability. Delivery costs are impacted by the price of diesel. Should diesel prices increase, we incur additional fuel surcharges from freight companies that cannot be passed on to our customers that have been quoted a delivered price. A material increase in the price of diesel could have a material adverse effect on the Company’s profitability. Governmental fiscal and budgetary constraints and legislative impasses may adversely impact our financial condition and results of operations in various ways. Governmental fiscal and budgetary constraints and legislative impasses may adversely impact our financial condition and results of operations in various ways, including possible reduced funding for transportation programs by federal, state and local governmental agencies which could reduce demand for our products from our construction customers. Our mining and other operations are subject to operating risks that are beyond our control, which could result in materially increased operating expenses and decreased production and shipment levels that could materially adversely affect our Lime and Limestone Operations and their profitability. We mine limestone in open pit and underground mining operations and process and distribute that limestone through our plants and other facilities. Certain factors beyond our control could disrupt our operations, adversely affect production and shipments and increase our operating costs, all of which could have a material adverse effect on our results of operations, including geological formation problems that may cause poor mining conditions, an accident or other major incident at a site that may cause all or part of our operations to cease for some period of time and increase our expenses, mining, processing and plant equipment failures and unexpected maintenance problems that may cause disruptions and added expenses, strikes, job actions or other work stoppages that may disrupt our operations or those of our suppliers, contractors or customers and increase our expenses, and adverse weather conditions and natural disasters, such as heavy rains, flooding, ice storms, freezing weather, drought and other natural events, that may affect operations, transportation or customers. If any of these conditions or events occurs, our operations may be disrupted, we could experience a delay or halt of production or shipments, our operating costs could increase significantly and we could be exposed to fines, penalties, assessments and other liabilities. If our insurance coverage is limited or excludes certain of these conditions or events, we may not be able to recover any of the losses that we may incur as a result of such conditions or events, some of which may be substantial. We incur environmental compliance costs, including capital, maintenance and operating costs, with respect to pollution control equipment, the cost of ongoing monitoring programs, the cost of reclamation and remediation efforts and other similar costs and liabilities relating to our compliance with Environmental Laws, and we expect these costs and liabilities to continue to increase, including possible new costs, taxes and limitations on operations such as those related to possible climate change initiatives, including regulation of greenhouse gas emissions. The rate of change of Environmental Laws has been rapid over the last decade, and we may face possible new costs, taxes and limitations on operations, including those related to climate change initiatives. We believe our expenditure requirements for future environmental compliance, including complying with the new nitrogen dioxide, sulfur dioxide and ozone emission limitations under the NAAQS and regulation of greenhouse gas emissions, will continue to increase as operating, reporting and other environmental standards increase. Discovery of currently unknown conditions and unforeseen liabilities could require additional expenditures. 15 The regulation of greenhouse gas emissions remains an issue for the Company and other similar manufacturing companies. There is no assurance that changes in the law or regulations will not be adopted, such as the imposition of a carbon tax, a cap-and-trade program requiring the Company to purchase carbon credits, or other measures that would require reductions in emissions or changes to raw materials, fuel use or production rates, that could have a material adverse effect on the Company’s financial condition, results of operations, cash flows and competitive position. We intend to comply with all Environmental Laws and believe our accrual for environmental liabilities at December 31, 2013 is reasonable. Because many of the requirements are subjective and therefore not quantifiable or presently determinable, or may be affected by additional legislation and rulemaking, including those related to climate change and greenhouse gas emissions, there is no assurance that we will be able to continue to renew our operating permits, and it is not possible to accurately predict the aggregate future costs and liabilities relating to environmental compliance and their effect on our financial condition, results of operations, cash flows and competitive position. To maintain our competitive position, we may need to continue to expand our operations and production capacity, obtain financing for any such expansion at reasonable interest rates and acceptable terms and sell the resulting increased production at acceptable prices. We may undertake various modernization, expansion and development projects and acquisitions. These may require that we incur additional debt, which may not be available to us at all or at reasonable interest rates or on acceptable terms. Given current and projected demand for lime and limestone products, we cannot guarantee that any such project or acquisition would be successful, that we would be able to sell any resulting increased production at acceptable prices or that any such sales would be profitable. Although prices for our lime and limestone products have been relatively firm in recent years, we are unable to predict future demand and prices, especially given the continuing economic difficulties, and cannot provide any assurance that current levels of demand and prices will continue or that any future increases in demand or prices can be maintained. The lime industry is highly regionalized and competitive. Our competitors are predominately large private companies. The primary competitive factors in the lime industry are quality, price, ability to meet customer demands and specifications, proximity to customers, personal relationships and timeliness of deliveries, with varying emphasis on these factors depending upon the specific product application. To the extent that one or more of our competitors becomes more successful with respect to any key competitive factor, our financial condition, results of operations, cash flows and competitive position could be materially adversely affected. Natural Gas Interests. Historically, the markets for natural gas have been volatile and may continue to be volatile in the future. Various factors that are beyond our control will affect the demand for, and prices of, natural gas, such as: (cid:127) the worldwide and domestic supplies of natural gas; (cid:127) the development of new technologies and reserves of natural gas in the United States; (cid:127) the price and level of U.S. exports and imports; (cid:127) the level of consumer and industrial demand; (cid:127) the price and availability of alternative fuels; 16 (cid:127) the availability of pipeline capacity; (cid:127) weather conditions; (cid:127) domestic and foreign governmental regulations and taxes; and (cid:127) the overall economic environment. The natural gas industry is cyclical in nature and tends to reflect general economic and gas supply conditions. Recent technological advances, such as hydraulic fracturing, have enabled the industry to access additional reserves and have greatly increased the current supply of natural gas in the United States, resulting in lower natural gas prices. Lower natural gas prices may reduce the amount of natural gas that is economical for our operators to develop and produce on the O & G Properties or cause them to shut in wells for extended periods of time or to plug and abandon wells. Reduced prices and production could severely reduce our revenues, gross profit and cash flows from our Natural Gas Interests and thus could have a material adverse effect on our financial condition, results of operations and cash flows. We do not control development and production operations on the O & G Properties, which could impact our Natural Gas Interests. As the owner of royalty and non-operating working interests, our ability to influence development of, and production from, the O & G Properties is severely limited. All decisions related to development and production on the O & G Properties will be made by the operators and may be influenced by factors beyond our control, including but not limited to natural gas prices, pipeline capacities, interest rates, budgetary considerations and general industry and economic conditions. The occurrence of an operational risk or uncertainty that materially impacts the operations of the operators of the O & G Properties could have a material adverse effect on the amount we receive in connection with our interests in production from the O & G Properties, which could have a material adverse effect on our financial condition, results of operations and cash flows. Our natural gas income is affected by development, production and other costs, some of which are outside of our control, and possible unitizations. The natural gas income that comes from our working interests, and to a lesser extent our royalty interests, is directly affected by increases in development, production and other costs, as well as unitizations of existing wells. Some of these costs are outside our control, including drilling and production costs, costs of regulatory compliance and severance and other similar taxes. Other expenditures are dictated by business necessity, such as drilling additional wells or working over existing wells to increase recovery rates. Our natural gas reserves are depleting assets, and we have no ability to explore for new reserves. In addition, our ability to increase our proved developed reserves is limited to the drilling of potential additional wells and workovers of existing wells by the operators on the O & G Properties. Our revenues from our Natural Gas Interests depend in large part on the quantity of natural gas developed and produced from the O & G Properties. Our producing wells will naturally experience declines in production rates due to depletion of their natural gas reserves, and the operators may determine to temporarily shut in or to plug and abandon a producing well if they believe that it is no longer economical to continue production from the well. We have no ability to explore for new reserves. Any increases in our proved developed reserves will come from the drilling of additional wells or working over existing wells on the O & G Properties. The timing and number of such additional wells or workover of existing wells, if any, depend on the market prices of natural gas and on other factors beyond our control. 17 Drilling activities on the O & G Properties may not be productive, which could have an adverse effect on our financial condition, results of operations and cash flows. Drilling involves a wide variety of risks, including the risk that no commercially productive natural gas reservoirs will be encountered. The cost of drilling, completing, working over and operating wells is often uncertain, and drilling operations may be delayed or canceled as a result of a variety of factors, including: (cid:127) Pressure or irregularities in formations; (cid:127) Equipment failures or accidents; (cid:127) Unexpected drilling conditions; (cid:127) Shortages or delays in the delivery of equipment; and (cid:127) Adverse weather conditions. Future drilling activities, if any, or workovers on the O & G Properties may not be successful. If these activities are unsuccessful, this failure could have an adverse effect on our financial condition, results of operations and cash flows. A natural disaster, accident or catastrophe could damage pipelines, gathering systems and other facilities that service wells on the O & G Properties, which could substantially limit operations and adversely affect our financial condition, results of operations, and cash flows. If pipelines, gathering systems or other facilities that serve the O & G Properties are damaged by any natural disaster, accident, catastrophe or other event, revenues from our Natural Gas Interests could be significantly interrupted. Any event that interrupts the development, production, gathering or transportation of our natural gas, or which causes us to share in significant expenditures not covered by insurance, could adversely impact our gross profit from our Natural Gas Interests. We do not carry business interruption insurance on our Natural Gas Interests. The O & G Properties are geographically concentrated, which could cause net proceeds to be impacted by regional events, including natural disasters and reduced pipeline capacity resulting from production from other wells in the area. The O & G Properties are all natural gas properties located exclusively in the Barnett Shale Formation. Because of this geographic concentration, any regional events, including natural disasters and production from other wells in the area, that increase costs, reduce availability of equipment, supplies or pipeline capacity, reduce demand or limit production could impact our gross profit from our Natural Gas Interests more than if the Properties were more geographically diversified. The number of prospective natural gas purchasers and methods of delivery for our gas are also considerably less than would otherwise exist from a more geographically diverse group of interests. Governmental policies, laws and regulations could have an adverse impact on the O & G Properties and our natural gas business. The O & G Properties and our natural gas business are subject to federal, state and local laws and regulations relating to the oil and natural gas industry, as well as regulations relating to health and safety matters. These laws and regulations can have a significant impact on the costs and amount of development and production. 18 Environmental costs and liabilities and changing environmental regulation associated with the O & G Properties could adversely affect our financial condition, results of operations and cash flows. As with other companies engaged in the ownership, development and production of natural gas, we expect to have some risk of exposure to environmental costs and liabilities. The costs associated with environmental compliance or remediation could reduce the gross profits we would receive from our Natural Gas Interests. The O & G Properties are subject to extensive federal, state and local regulatory requirements relating to environmental affairs, health and safety and waste management. Increased regulation of natural gas drilling and production could increase development and production costs on the O & G Properties and adversely affect our cash flows. Third parties could also pursue legal actions to enforce compliance or assert claims for damages. Further, under certain environmental laws and regulations, the operators of the underlying properties could also be subject to joint and several, strict liability for the removal or remediation of released materials or property contamination from drilling, including hydraulic fracturing, or waste disposal, regardless of whether the operators were responsible for the release or contamination or if the operations were in compliance with all applicable laws. Drought conditions and increasing demands on the water supply for municipal, agricultural, and other uses may limit the availability of and/or increase the cost of the large volumes of water required for hydraulic fracturing. It is likely that our expenditures in connection with environmental matters, as part of normal capital expenditure programs, will affect the profitability of the O & G Properties. Future Environmental Law developments, such as stricter laws, regulations or enforcement policies, including climate change legislation mandating specific near-term and long-range reductions in greenhouse gas emissions or increased regulation of hydraulic fracturing, could significantly increase the costs of production from the O & G Properties and adversely affect our financial condition, results of operations and cash flows.

OVERVIEW. General. We have identified two business segments based on the distinctness of their activities and products: Lime and Limestone Operations and Natural Gas Interests. All operations are in the United States. In evaluating the operating results of our segments, management primarily reviews revenues and gross profit. We do not allocate corporate overhead or interest costs to our business segments. Our Lime and Limestone Operations represent our principal business. Our Natural Gas Interests consist of royalty and non-operating working interests under the O & G Lease and the Drillsite Agreement with two separate operators related to our Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime conducts its lime and limestone operations. Our principal management decisions related to our Natural Gas Interests involve whether to participate as a non-operating working interest owner by contributing our proportional costs for drilling proposed wells or workovers of existing wells under the O & G Lease and the Drillsite Agreement. While we intend to continue to participate in future natural gas wells drilled and workovers of existing wells on our O & G Properties, if any, we are not in the business of drilling for or producing natural gas, and have no personnel expert in that field. Revenues from our Lime and Limestone Operations decreased 2.6% in 2013 compared to 2012. The decreased sales volumes of our lime and limestone products, which accounted for a revenue decrease of approximately 3.8% for 2013 compared to 2012, resulted principally from reduced sales volumes to our steel customers, partially offset by increased sales volumes to our construction and environmental customers, although we had reduced demand from our construction customers in the fourth quarter 2013 due to inclement weather conditions compared to favorable weather conditions in the fourth quarter 2012. This decrease in sales volumes was partially offset by average product price increases of approximately 1.2% for our lime and limestone products in 2013 compared to 2012. Revenues from our Natural Gas Interests decreased $1.4 million, or 19.1%, to $5.8 million in 2013 from $7.1 million in 2012 primarily due to decreased production volumes resulting from the normal declines in production rates on the Company’s existing natural gas wells. The decrease in revenues from our Natural Gas Interests in 2013 resulted from lower production volumes in 2013 (approximately 21.2%), partially offset by price increases in 2013 (approximately 2.1%). Our gross profit decreased 7.9% in 2013 compared to 2012. Gross profit from our Lime and Limestone Operations in 2013 decreased 5.4% compared to 2012 primarily due to the decreased revenues discussed above and increased cost of revenues in the fourth quarter 2013 resulting from production inefficiencies due to the inclement weather conditions, partially offset by a reduction in our 23 stripping costs of approximately $0.6 million in 2013 compared to 2012. The timing and amount of our stripping costs in the future will depend upon, among other things, the availability and cost-effective utilization of contractors and their equipment and our employees and equipment, but we believe the costs of our ongoing stripping will be at approximately the same rate to production as we incurred in 2013. Our gross profit from our Natural Gas Interests decreased 26.7% in 2013 compared to 2012 due to the decreased revenues discussed above. These decreases in gross profit resulted in a $1.6 million, or 9.9%, decrease in our net income in 2013 compared to 2012. Cash flows from operations during 2012 enabled us to continue to service our bank debt, make $8.9 million of capital investments, and leave us with cash balances of $49.5 million at December 31, 2013 compared to $29.8 million at December 31, 2012. Our significant cash flows and strong balance sheet enabled us to declare a quarterly cash dividend to our shareholders payable on March 20, 2014. Lime and Limestone Operations. In our Lime and Limestone Operations, we produce and sell PLS, quicklime, hydrated lime and lime slurry. The principal factors affecting our success are the level of demand and prices for our products and whether we are able to maintain sufficient production levels and product quality while controlling costs. Inclement weather conditions generally reduce the demand for lime and limestone products supplied to construction-related customers that account for a significant amount of our revenues. Inclement weather also interferes with our open-pit mining operations and can disrupt our plant production, as in the case of winter ice storms and freezing weather. In addition to weather, various maintenance, environmental, accident and other operational issues can also disrupt our operations and increase our operating expenses. Demand for our products in our market areas is also affected by general economic conditions, the pace of home and other construction, the demand for steel, and the level of oil and gas drilling in our markets, as well as the level of governmental and private funding for highway construction. Demand for our lime products from our construction and environmental customers improved during 2013, while demand from our steel customers declined. In addition, inclement weather in the fourth quarter 2013, compared to favorable weather conditions in the comparable 2012 quarter, resulted in a significant decline in construction demand for our lime and limestone products during that period. However, we believe that this demand was merely postponed until 2014 as our customers’ projects are still underway. On July 6, 2012, the President signed into law the Moving Ahead for Progress in the 21st Century Act (‘‘MAP-21’’), the first multi-year transportation authorization enacted since 2005. MAP-21 funds surface transportation programs at over $105 billion for fiscal years 2013 and 2014, continuing the previous level of funding plus inflation. Funding under MAP-21will expire September 30, 2014, unless the Congress passes a continuing resolution, as it has done in the past, or enacts new legislation. In addition, the Highway Trust Fund, which is funded mostly from excise taxes on gasoline and certain other motor fuels, has over the past several years required transfers from the general fund of the Treasury to cover shortfalls in funding as excise taxes have failed to cover the Fund’s obligations. The chairman of the Senate Environment and Public Works Committee recently announced that she hopes to have a new transportation authorization before the Committee by April 2014 in an effort to give the Senate Finance Committee ample time to consider funding options for a new surface transportation bill. Although governmental funding of public sector projects remains a concern, we continue to see an increase in the construction of tollroads in Texas. Our modernization and expansion projects in Texas and Arkansas, including the construction of a third kiln in Arkansas (completed in December 2006), our development projects in Arkansas, and our acquisitions of U. S. Lime Company—St. Clair, our Delta, Colorado facilities and our Texas slurry 24 operations have positioned us to meet the demand for high-quality lime and limestone products in our markets, with our lime output capacity more than doubling since 2003. In addition, our distribution terminal in Shreveport, Louisiana has expanded our market area for this additional output. Our modernization and expansion and development projects have also equipped us with up-to-date, fuel-efficient plant facilities, which has resulted in lower production costs and greater operating efficiencies, thus enhancing our competitive position. All of our kilns are fuel-efficient preheater kilns, except for one kiln at St. Clair. For our plants to operate at peak efficiency, we must meet operational challenges that arise from time to time, including bringing new facilities on line and refurbishing and/or improving acquired facilities, such as St. Clair, which we acquired with the intention of modernizing and expanding, subject to permitting and future economic outlook, as well as operating existing facilities efficiently. We also incur ongoing costs for maintenance and to remain in compliance with rapidly changing Environmental Laws and health and safety and other regulations. Our primary variable cost is energy. Prices for coal, petroleum coke, diesel, electricity, transportation and freight have generally increased over the past few years. Domestic coal and petroleum coke are also being exported, increasing competition and prices for the domestic supply. In addition, our freight costs, including diesel prices, to deliver our products can be high relative to the value of our products and have increased significantly in recent years. We have been able to mitigate to some degree the adverse impact of these energy cost increases by varying the mixes of fuel used in our kilns, and by passing on some of our increased costs to our customers through higher prices and/or surcharges on certain products. We have not engaged in any significant hedging activity in an effort to control our energy costs, but may do so in the future. We have financed our modernization and expansion and development projects and acquisitions through a combination of debt financing and cash flows from operations. We must generate sufficient cash flows to cover ongoing capital, including possible modernization and expansion and development projects, and debt service needs. Our revolving credit facility matures June 1, 2015, and the remainder of our long-term debt becomes due at the end of 2015. Absent a significant acquisition opportunity arising, we anticipate funding our capital requirements, including our possible modernization and development projects, continuing to service our debt and paying cash dividends from our cash on hand and cash flows from operations. For us to increase our profitability in our Lime and Limestone Operations in the face of our increased fixed and variable costs, we must improve our revenues and control our operational and selling, general and administrative expenses. To maintain or improve our gross profit margins, we are focusing on maintaining, and increasing where possible, our lime and limestone prices to offset our increased costs, which is a challenging task in these difficult economic times. In addition, we will continue to explore ways to expand our operations and production capacity through major development projects, including the possible modernization of our St. Clair plant, and acquisitions as conditions warrant or opportunities arise. We continue to believe the enhanced production capacity resulting from our modernization and expansion and development projects at Texas and Arkansas, our acquisitions and the operational strategies we have implemented have allowed us to increase production capacity, improve product quality, better serve existing customers, attract new customers and control our costs. There can be no assurance, however, that demand and prices for our lime and limestone products will be sufficient to fully utilize our additional production capacity and cover our additional depreciation, depletion and other fixed costs; that our production will not be adversely affected by weather, maintenance, accident or other operational issues; that we can successfully invest in improvements to our existing facilities; that our results will not be adversely affected by continued increases in fuel, electricity, transportation 25 and freight costs or new environmental, health and safety or other regulatory requirements; or that our revenues, gross profit, net income and cash flows can be maintained or improved. Natural Gas Interests. In 2004, we entered into the O & G Lease with EOG with respect to oil and gas rights on our Cleburne, Texas property, located in the Barnett Shale Formation. Pursuant to the O & G Lease, we have royalty interests ranging from 15.4% to 20% in oil and gas produced from any successful wells drilled on the leased property and an option to participate in any well drilled on the leased property as a 20% non-operating working interest owner. Our overall average revenue interest is 34.7% in the 33 wells drilled under the O & G Lease that are currently producing. In November 2006, we also entered into a Drillsite Agreement with XTO that has an oil and gas lease covering approximately 538 acres of land contiguous to our Johnson County, Texas property. Pursuant to this Agreement, we have a 3% royalty interest and an optional 12.5% non-operating working interest, resulting in a 12.4% interest in revenues in the six XTO wells drilled and producing from a padsite located on our property. Eight new wells were drilled in the fourth quarter 2009 and first quarter 2010 pursuant to the O&G Lease, five of which were completed as producing wells during the fourth quarter 2010, and three of which were completed as producing wells in late June 2011. In addition, two wells were drilled in the first quarter 2010 and completed as producing wells in the third quarter 2010 pursuant to the Drillsite Agreement. No new wells have been drilled since 2010 or are currently being drilled. We cannot predict the number of additional wells that ultimately will be drilled on the O & G Properties, if any, or their results. The pricing of natural gas sales is primarily determined by supply and demand in the marketplace and can fluctuate considerably. The prices that the Company receives for its natural gas production is also affected by the amount of natural gas liquids included in the natural gas and the prices for those liquids which is also subject to supply and demand factors. Prices of both natural gas and natural gas liquids declined dramatically in recent years due to increased supply, although prices for natural gas have risen recently due to cold winter weather conditions. CRITICAL ACCOUNTING POLICIES. The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (‘‘US GAAP’’). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities, at the date of our financial statements. Actual results may differ from these estimates and judgments under different assumptions or conditions and historical trends. Critical accounting policies are defined as those that are reflective of significant management judgments and uncertainties and potentially result in materially different results under different assumptions and conditions. We believe the following critical accounting policies require the most significant management estimates and judgments used in the preparation of our consolidated financial statements. Accounts receivable. We estimate the collectability of our trade receivables. A considerable amount of judgment is required in assessing the ultimate realization of these receivables and determining our allowance for doubtful accounts. Uncollected trade receivables are charged-off when identified by management to be unrecoverable. The majority of our trade receivables are unsecured. Payment terms for our trade receivables are based on underlying purchase orders, contracts or 26 purchase agreements. Credit losses relating to these receivables have generally been within management expectations and historical trends. Successful-efforts method for Natural Gas Interests. We use the successful-efforts method to account for development expenditures related to our Natural Gas Interests. Under this method, drilling and completion costs of development wells are capitalized and depleted using the units-of-production method. Costs to drill exploratory wells, if any, that do not find proved reserves are expensed. Reserve estimates. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain it will commence the project within a reasonable time. The volumes of our reserves are estimates that, by their nature, are subject to revision. The estimates are made using geological and reservoir data, as well as production performance data. These estimates will be reviewed annually and revised, either upward or downward, as warranted by additional performance data. If the estimates of proved reserves were to decline, the rate at which we record depletion expense would increase. Environmental costs and liabilities. We record environmental accruals in other liabilities, based on studies and estimates, when it is probable we have incurred a reasonably estimable cost or liability. The accruals are adjusted when further information warrants an adjustment. Environmental expenditures that extend the life, increase the capacity or improve the safety or efficiency of Company- owned assets or are incurred to mitigate or prevent future possible environmental issues are capitalized. Other environmental costs are expensed when incurred. Contingencies. We are party to proceedings, lawsuits and claims arising in the normal course of business relating to regulatory, labor, product and other matters. We are required to estimate the likelihood of any adverse judgments or outcomes with respect to these matters, as well as potential ranges of possible losses. A determination of the amount of reserves required, if any, for these contingencies is made after careful analysis of each individual matter, including coverage under our insurance policies. This determination may change in the future because of new information or developments. Derivatives. We record the fair value of our interest rate hedges on our Consolidated Balance Sheets and include any changes in fair value in comprehensive income (loss). We determine fair value utilizing the cash flows valuation technique. Stock-based compensation. We expense all stock-based payments to employees and directors, including grants of stock options and restricted stock, in our Consolidated Statements of Income based on their fair values. Compensation cost is recognized ratably over the vesting period for all stock-based awards. 27 RESULTS OF OPERATIONS.

Revenues from our Lime and Limestone Operations for 2013 decreased $3.4 million, or 2.6%, to $128.0 million from $131.4 million in 2012. The decrease in revenues from our Lime and Limestone Operations was primarily due to decreased sales volumes of our lime and limestone products, principally to our steel customers, partially offset by increased sales volumes to the Company’s construction and environmental customers and a slight increase in prices realized for the Company’s lime and limestone products in 2013, compared to 2012. Revenues from our Natural Gas Interests for 2013 decreased $1.4 million, or 19.1%, to $5.8 million from $7.1 million in 2012. The decrease in revenues from our Natural Gas Interests resulted from the normal declines in production rates on existing wells, partially offset by slightly higher prices. Our gross profit decreased to $30.8 million for 2013 from $33.4 million for 2012, a decrease of $2.6 million, or 7.9%. Gross profit from our Lime and Limestone Operations for 2013 was $27.9 million, compared to $29.5 million in 2012, a decrease of $1.6 million, or 5.4%. The decrease in gross profit for our Lime and Limestone Operations in 2013 compared to 2012 resulted primarily from the decreased revenues discussed above and additional cost of revenues in the fourth quarter 2013 due to inclement weather conditions discussed above, partially offset by the reduced stripping costs in 2013 discussed above. Gross profit for 2013 also included $2.9 million from our Natural Gas Interests, compared to $3.9 million in 2012, a decrease of $1.1 million, or 26.7%. There were 39 producing wells in both 2013 and 2012. Production volumes for 2013 from our Natural Gas Interests totaled 1.0 BCF, sold at an average price per MCF of $5.86, compared to 2012 when 1.2 BCF was produced and sold at an average price of $5.74 per MCF. 28 Selling general and administrative expenses (‘‘SG&A’’) decreased to $9.1 million for 2013 from $9.2 in 2012, a decrease of $44 thousand, or 0.5%. As a percentage of revenues, SG&A increased to 6.8% in 2013 from 6.6% in 2012 due to the decrease in revenues for 2013. Interest expense for 2013 decreased to $1.9 million from $2.2 million in 2012, a decrease of $0.3 million, or 14.4%. Interest expense in 2013 included $1.1 million paid in quarterly settlement payments pursuant to our interest rate hedges, compared to $1.3 million paid in 2012. The decrease in interest expense in 2013 resulted from decreased average outstanding debt. Income tax expense decreased to $5.0 million for 2013 from $5.7 million in 2012, a decrease of $645 thousand, or 11.4%. The decrease in income tax expense in 2013 compared to 2012 was primarily due to the decrease in our income before taxes. Our effective income tax rate for 2013 decreased to 25.4% compared to our 2012 rate of 25.7%. Net income decreased by $1.6 million, or 9.9%, to $14.8 million ($2.66 per share diluted), compared to net income of $16.4 million ($2.87 per share diluted) in 2012. 2012 vs. 2011 Revenues for 2012 decreased to $138.5 million from $142.6 million in 2011, a decrease of $4.1 million, or 2.8%. Revenues from our Lime and Limestone Operations for 2012 increased $1.7 million, or 1.3%, to $131.4 million from $129.7 million in 2011. The increase in revenues from our Lime and Limestone Operations was primarily due to increased prices realized for our lime and limestone products in 2012, compared to 2011, partially offset by decreased sales volumes of lime and limestone products principally due to decreased demand from our steel and oil and gas services customers. Revenues from our Natural Gas Interests for 2012 decreased $5.8 million, or 44.7%, to $7.1 million from $12.9 million in 2011. The decrease in revenues from our Natural Gas Interests resulted from decreased average prices received per MCF, principally as a result of decreased prices for both natural gas and liquids contained in our natural gas, and the normal declines in production rates on existing wells. Natural Gas Interests revenues for 2011 also included $487 thousand from the final favorable resolution of certain royalty ownership issues on unitized natural gas wells. Our gross profit decreased to $33.4 million for 2012 from $41.3 million for 2011, a decrease of $7.9 million, or 19.1%. Gross profit from our Lime and Limestone Operations for 2012 was $29.5 million, compared to $32.1 million in 2011, a decrease of $2.6 million, or 8.2%. The decrease in gross profit in 2012 compared to 2011 resulted primarily from contractor stripping costs of $2.6 million incurred principally in the second and third quarters 2012, compared to no such contractor stripping costs in 2011. Gross profit for 2012 also included $3.9 million from our Natural Gas Interests, compared to $9.2 million in 2011, a decrease of $5.3 million or 57.2%. There were 39 producing wells at both December 31, 2012 and 2011. Production volumes for 2012 from our Natural Gas Interests totaled 1.2 BCF, sold at an average price per MCF of $5.74, compared to 2011 when 1.6 BCF was produced and sold at an average price of $8.27 per MCF. In addition, 2011 included a $463 thousand contribution to gross profit from the resolution of certain royalty ownership issues. SG&A increased to $9.2 million for 2012 from $8.8 million in 2011, an increase of $347 thousand, or 3.9%. As a percentage of revenues, SG&A increased to 6.6% in 2012 from 6.2% in 2011. The increase in SG&A in 2012 was primarily attributable to increased non-cash stock-based compensation costs, which increased $204 thousand, or 29.6%, compared to 2011, due to increases in the price per share of the Company’s common stock on the most recent grant dates, compared to the prices per share on previous grant dates. 29 Interest expense in 2012 decreased to $2.2 million from $2.5 million in 2011, a decrease of $332 thousand, or 13.3%. Interest expense in 2012 and 2011 included $1.3 million and $1.6 million, respectively, paid in aggregate quarterly settlement payments pursuant to our interest rate hedges. The decrease in interest expense in 2012 resulted from decreased average outstanding debt. Income tax expense decreased to $5.7 million in 2012 from $8.0 million in 2011, a decrease of $2.3 million, or 28.6%. The decrease in income tax expense in 2012 compared to 2011 was primarily due to the decrease in our income before taxes. Our effective income tax rate for 2012 decreased to 25.7% compared to our 2011 rate of 26.4% primarily because of proportionately higher statutory depletion rates as a percentage of pretax income in 2012 compared to 2011. Net income decreased to $16.4 million ($2.87 per share diluted) in 2012, compared to $22.2 million ($3.49 per share diluted) in 2011, a decrease of $5.8 million, or 26.0%. Earnings per share for 2012 was favorably impacted by $0.32 per share by the Company’s repurchase of 200,000 shares of its common stock during the third quarter 2011 and 700,000 shares of common stock in the first quarter 2012. Earnings per share for 2011 was favorably impacted by $0.04 per share by the 2011 repurchase of 200,000 shares of common stock. FINANCIAL CONDITION. Capital Requirements. We require capital primarily for seasonal working capital needs, normal recurring capital and re-equipping projects, modernization and expansion and development projects, drilling, completion and working over of natural gas wells and acquisitions. Our capital needs are met principally from cash on hand, cash flows from operations and our $30 million revolving credit facility. We expect to spend approximately $7.0 million to $9.0 million per year over the next several years in our Lime and Limestone Operations for normal recurring capital and re-equipping projects at our plants and facilities to maintain or improve efficiency, ensure compliance with Environmental Laws, meet customer needs and reduce costs. As of December 31, 2013, we had no material open orders or contractual commitments for our Lime and Limestone Operations and Natural Gas Interests. Liquidity and Capital Resources. Net cash provided by operations was $33.5 million for 2013, compared to $31.7 million in 2012, an increase of $1.8 million, or 5.8%. Our cash provided by operating activities is composed of net income, depreciation, depletion and amortization (‘‘DD&A’’), other non-cash items included in net income and changes in working capital. In 2013, cash provided by operating activities was principally composed of $14.8 million net income, $14.5 million DD&A, $1.7 million deferred income taxes, $0.9 million of stock-based compensation and $1.4 million from changes in operating assets and liabilities. The increase in 2013 compared to 2012 was primarily the result of the $0.4 million decrease in inventories in 2013 compared to a $3.4 million increase in 2012, and the $0.6 million increase in accounts payable and accrued expenses in 2013 compared to a $1.1 million decrease in 2012. These increases were partially offset by the $1.6 million decrease in net income in 2013. Net cash used in investing activities was $8.7 million for 2013 compared to $8.3 million in 2012, primarily for normal recurring capital and re-equipping projects at our plants and facilities. Net cash used in financing activities primarily consisted of $5.0 million to repay term loans in 2013, compared to $6.25 million in 2012, and $0.2 million to repurchase shares of our common stock in 2013, compared to $40.8 million in 2012. Our cash and cash equivalents at December 31, 2013 increased to $49.5 million from $29.8 million at December 31, 2012. Banking Facilities and Other Debt Our credit agreement includes a ten-year $40 million term loan (the ‘‘Term Loan’’), a ten-year $20 million multiple draw term loan (the ‘‘Draw Term Loan’’) and a $30 million revolving credit facility (the ‘‘Revolving Facility’’) (collectively, the ‘‘Credit Facilities’’). At December 31, 2013, we had $660 thousand of letters of credit issued, which count as draws under the 30 Revolving Facility. Pursuant to a security agreement, dated August 25, 2004, the Credit Facilities are secured by our existing and hereafter acquired tangible assets, intangible assets and real property. Under the Credit Facilities, we may pay dividends so long as it remains in compliance with the provisions of the Facilities, and may purchase, redeem or otherwise acquire shares of its common stock so long as its pro forma Cash Flow Leverage Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase. The Term Loan requires quarterly principal payments of $833, with a final principal payment of $10.0 million due on December 31, 2015. The Draw Term Loan requires quarterly principal payments of $417, with a final principal payment of $6.7 million due on December 31, 2015. The Revolving Facility matures on June 1, 2015. The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility can be accelerated if any event of default, as defined under the Credit Facilities, occurs. The Revolving Facility commitment fee ranges from 0.250% to 0.400%. In addition, the Credit Facilities bear interest, at our option, at either LIBOR plus a margin of 1.750% to 2.750%, or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%. The Revolving Facility commitment fee and the interest rate margins are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion and amortization (‘‘EBITDA’’) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Our maximum Cash Flow Leverage Ratio is 3.25 to 1. We have hedges, with Wells Fargo Bank, N.A as the counterparty, that fix LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively. Based on the current LIBOR margin of 1.750%, since June 1, 2010 our interest rates have been: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan. The hedges have been effective as defined under applicable accounting rules. Therefore, changes in fair value of the interest rate hedges are reflected in comprehensive income (loss). We will be exposed to credit losses in the event of non-performance by the counterparty to the hedges. Due to interest rate declines, our mark to market of the interest rate hedges, at December 31, 2013 and December 31, 2012, resulted in liabilities of $1.5 million and $2.6 million, respectively, which are included in accrued expenses ($0.9 and $1.1 million, respectively) and other liabilities ($0.6 million and $1.5 million, respectively) on our Consolidated Balance Sheets. We paid $1.1 and $1.3 million in aggregate quarterly settlement payments pursuant to the hedges in 2013 and 2012, respectively. These payments were included in interest expense in our Consolidated Statements of Income. During 2013, we paid $5.0 million of the $26.7 million in total principal amount of debt outstanding as of December 31, 2012, resulting in $21.7 million of total principal amount of debt outstanding as of December 31, 2013, consisting of $13.4 million and $8.3 million outstanding on the Term Loan and Draw Term Loan, respectively. We had $660 thousand of letters of credit issued under the Revolving Facility as of December 31, 2013, but no cash draws. Capital Expenditures. We have made a substantial amount of capital investments over the past several years to modernize our plants and facilities and expand our lime and limestone operations, and to fund the drilling and completion of 40 natural gas wells. Investing activities totaled $8.9 and $8.3 million, in 2013 and 2012, respectively. Investments in 2013 and 2012 included approximately $58 and $81 thousand, respectively, for workover costs for our non-operating working interests in natural gas wells. 31 Common Stock Buybacks. The Company spent $0.2, $40.8 and $8.3 million in 2013, 2012 and 2011, respectively, to purchase treasury shares, including $40.6 million in the first quarter 2012 to repurchase 700,000 shares and $8.1 million in the third quarter 2011 to repurchase 200,000 shares in privately negotiated transactions. The 700,000 shares were repurchased for $58.00 per share, a 2.2% discount from the most recent closing market price of the common stock prior to the transaction. The 200,000 shares were repurchased for $40.65 per share, a discount of 2.0% from the most recent closing market price of the common stock prior to the transaction. Contractual Obligations. The following table sets forth our contractual obligations as of December 31, 2013 (in thousands): Payments Due by Period Contractual Obligations Total 1 Year 2 - 3 Years 4 - 5 Years Long-term debt, including current installments . . . .

(2) These obligations are recorded on the Consolidated Balance Sheet at December 31, 2013. (3) Does not include $10 unfunded projected benefit obligation for a defined benefit pension plan. Future required contributions, if any, are subject to actuarial assumptions and future earnings on plan assets. We currently have no plans to make a contribution to the plan in 2014. See Note 6 of Notes to Consolidated Financial Statements. (4) Does not include $1.5 million mark-to-market liability for our interest rate hedges. As of December 31, 2013, we had $660 thousand of letters of credit outstanding and no other draws on our $30 million Revolving Facility. We believe that cash on hand and cash generated from operations will be sufficient to meet our operating needs, ongoing capital needs, including the capital for possible modernization and development projects, debt service needs and liquidity needs and pay cash dividends for the near future. Off-Balance Sheet Arrangements. We do not utilize off-balance sheet financing arrangements; however, we lease railcars, corporate office space and some equipment used in our operations under operating lease agreements that are either non-cancelable or subject to significant penalty upon cancellation, and have various limestone mineral leases. As of December 31, 2013, the total future lease payments under our various operating and mineral leases totaled $4.3 million and $1.9 million, respectively, and are due in payments as summarized in the table above. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK. INTEREST RATE RISK. We are exposed to changes in interest rates, primarily as a result of floating interest rates on our Term Loan, Draw Term Loan and Revolving Facility. As of December 31, 2013, we had $21.7 million of indebtedness outstanding under floating rate debt. We have entered into interest rate swap agreements to swap floating rates for fixed rates at 4.695%, plus the applicable LIBOR margin, through maturity on the Term Loan balance of $13.4 million, and 4.875% and 5.500% on $6.2 million and $2.1 million, respectively, plus the applicable LIBOR margin, through maturity on the Draw Term Loan balance. There was no outstanding balance on the Revolving Facility subject to interest rate risk at December 31, 2013. Any future borrowings under the Revolving Facility would be subject to interest rate risk. See Note 3 of Notes to Consolidated Financial Statements. 32 ITEM 8.

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of United States Lime & Minerals, Inc. and Subsidiaries as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 7, 2014 expressed an unqualified opinion. /s/ GRANT THORNTON LLP Dallas, Texas March 7, 2014 34 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors and Shareholders United States Lime & Minerals, Inc. and Subsidiaries We have audited the internal control over financial reporting of United States Lime & Minerals, Inc. and Subsidiaries (the ‘‘Company’’) as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in the 1992 Internal Control— Integrated Framework issued by COSO. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements of the Company as of and for the year ended December 31, 2013, and our report dated March 7, 2014 expressed an unqualified opinion on those financial statements. /s/ GRANT THORNTON LLP Dallas, Texas March 7, 2014 35 United States Lime & Minerals, Inc.

Notes to Consolidated Financial Statements (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (1) Summary of Significant Accounting Policies (a) Organization United States Lime & Minerals, Inc. (the ‘‘Company’’) is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment), oil and gas services, industrial (including paper and glass manufacturers), roof shingle and agriculture (including poultry and cattle feed producers) industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company—Shreveport, U.S. Lime Company—St. Clair and U.S. Lime Company—Transportation. In addition, the Company, through its wholly owned subsidiary, U.S. Lime Company—O & G, LLC, has royalty and non-operating working interests in natural gas wells located in Johnson County, Texas, in the Barnett Shale Formation. (b) Principles of Consolidation The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated. (c) Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (‘‘US GAAP’’) requires management to make estimates and judgments that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates and judgments. (d) Statements of Cash Flows For purposes of reporting cash flows, the Company considers all certificates of deposit and highly- liquid debt instruments, such as U.S. Treasury bills and notes, with maturities, at the time of purchase, of three months or less to be cash equivalents. Cash equivalents are carried at cost plus accrued interest, which approximates fair market value. Supplemental cash flow information is presented below: Cash paid during the year for: Interest . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $1,746 $2,069 $2,395 Income taxes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $3,750 $3,000 $4,529 Years Ended December 31, 2013 2012 2011 (e) Revenue Recognition The Company recognizes revenue for its lime and limestone operations in accordance with the terms of its purchase orders, contracts or purchase agreements, which are generally upon shipment, and when payment is considered probable. Revenues include external freight billed to customers with related costs in cost of revenues. The Company’s returns and allowances are minimal. 41 United States Lime & Minerals, Inc. Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (1) Summary of Significant Accounting Policies (Continued) External freight billed to customers included in revenues was $25,536, $26,675 and $26,470 for 2013, 2012 and 2011, respectively, which approximates the amount of external freight billed to customers included in cost of revenues. Sales taxes billed to customers are not included in revenues. For its natural gas interests, the Company recognizes revenue in the month of production and delivery. (f) Fair Values of Financial Instruments Fair value is defined as ‘‘the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.’’ The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities. These tiers include: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Specific inputs used to value the Company’s interest rate swap liabilities included quoted 3 month LIBOR rates for the remaining life of the interest rate swaps. There were no changes in the methods and assumptions used in measuring fair value during the period. The carrying values of cash and cash equivalents, trade receivables, other current assets, accounts payable and accrued expenses approximate fair value due to the short maturity of these instruments. See Note 3 for debt fair values, which also approximate carrying values. The Company’s interest rate hedges are carried at fair value at December 31, 2013 and 2012. See Notes 1(p), 3 and 4. Financial liabilities measured at fair value on a recurring basis are summarized below: Fair Value Measurements as of December 31, Significant Other Observable Inputs (Level 2) 2013 2012 2013 2012 Valuation Technique Interest rate swap liabilities . . . . . . . . . . $(1,533) $(2,629) $(1,533) $(2,629) Cash flows approach (g) Concentration of Credit Risk and Trade Receivables Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents, trade receivables and derivative financial instruments. The Company places its cash and cash equivalents with high credit quality financial institutions and its derivative financial instruments with financial institutions and other firms that management believes have high credit ratings. The Company’s cash and cash equivalents at commercial banking institutions normally exceed federally insured limits. For a discussion of the credit risks associated with the Company’s derivative financial instruments, see Note 3. 42 United States Lime & Minerals, Inc. Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (1) Summary of Significant Accounting Policies (Continued) The majority of the Company’s trade receivables are unsecured. Payment terms for all trade receivables are based on the underlying purchase orders, contracts or purchase agreements. Credit losses relating to trade receivables have generally been within management expectations and historical trends. Uncollected trade receivables are charged-off when identified by management to be unrecoverable. Trade receivables are presented net of the related allowance for doubtful accounts, which totaled $238 and $525 at December 31, 2013 and 2012, respectively. Additions and write-offs to the Company’s allowance for doubtful accounts during the years ended December 31 are as follows: Beginning balance . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (1) Summary of Significant Accounting Policies (Continued) Maintenance and repairs are charged to expense as incurred; renewals and betterments are capitalized. When units of property are retired or otherwise disposed of, their cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is credited or charged to income. The Company expenses all exploration costs as incurred as well as costs incurred at an operating quarry or mine, other than capital expenditures and inventory. Costs to acquire mineral reserves or mineral interests are capitalized upon acquisition. Development costs incurred to develop new mineral reserves, to expand the capacity of a quarry or mine, or to develop quarry or mine areas substantially in advance of current production are capitalized once proven and probable reserves exist and can be economically produced. For each quarry or mine, capitalized costs to acquire and develop mineral reserves are depleted using the units-of-production method based on the proven and probable reserves for such quarry or mine. The Company reviews its long-lived assets for impairment and, when events or circumstances indicate the carrying amount of an asset may not be recoverable, the Company determines if impairment of value exists. If the estimated undiscounted future net cash flows are less than the carrying amount of the asset, an impairment exists, and an impairment loss must be calculated and recorded. If an impairment exists, the impairment loss is calculated based on the excess of the carrying amount of the asset over the asset’s fair value. Any impairment loss is treated as a permanent reduction in the carrying value of the asset. Through December 31, 2013, no events or circumstances arose that would require the Company to record a provision for impairment of its long-lived assets. (j) Successful-Efforts Method Used for Natural Gas Interests The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures. Under this method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and depleted using the units-of-production method. Costs to drill exploratory wells that do not find proved reserves are expensed. (k) Asset Retirement Obligations The Company recognizes legal obligations for reclamation and remediation associated with the retirement of long-lived assets at their fair value at the time the obligations are incurred (‘‘AROs’’). Over time, the liability for AROs is recorded at its present value each period through accretion expense, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company either settles the AROs for the recorded amount or recognizes a gain or loss. As of December 31, 2013 and 2012, the Company’s AROs included in other liabilities and accrued expenses were $1,320 and $1,397, respectively. Only $358 of assets associated with the Company’s AROs are not fully depreciated as of December 31, 2013. During 2013 and 2012, the Company spent $138 and $193 and recognized accretion expense of $61 and $51, respectively, on its AROs. The AROs were estimated based on studies and the Company’s process knowledge and estimates, and are discounted using an appropriate interest rate. The AROs are adjusted when further 44 United States Lime & Minerals, Inc.

December 31, 2013 2012 $ 90 105 $195 $136 109 $245 (m) Environmental Expenditures Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations, and which do not contribute to current or future revenue generation, are expensed. Liabilities are recorded at their present value when environmental assessments and/or remedial efforts are probable and the costs can be reasonably estimated. Generally, the timing of these accruals will coincide with completion of a feasibility study or the Company’s commitment to a formal plan of action. The Company incurred capital expenditures related to environmental matters of approximately $395 in 2013, $428 in 2012 and $407 in 2011.

Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (1) Summary of Significant Accounting Policies (Continued) (o) Stock-Based Compensation The Company expenses all stock-based payments to employees and directors, including grants of stock options and restricted stock, in the Company’s Consolidated Statements of Income based on their fair values. Compensation cost is recognized ratably over the vesting period. (p) Derivative Instruments and Hedging Activities Every derivative instrument (including certain derivative instruments embedded in other contracts) is recorded on the Company’s Consolidated Balance Sheets as either an asset or liability measured at its fair value. Changes in the derivative’s fair value are recognized currently in earnings unless specific hedge accounting criteria are met. The Company estimates fair value utilizing the cash flows valuation technique. The fair values of derivative contracts that expire in less than one year are recognized as current assets or liabilities. Those that expire in more than one year are recognized as long-term assets or liabilities. Derivative financial instruments that are not accounted for as hedges are adjusted to fair value through earnings. If the derivative is designated as a cash flow hedge, changes in fair value are recognized in comprehensive income (loss) until the hedged item is recognized in earnings. See Notes 1(f), 3 and 4. (q) Income Taxes The Company utilizes the asset and liability approach in its reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amount more likely than not to be realized. Income tax related interest and penalties are included in income tax expense. The Company also assesses individual tax positions to determine if they meet the criteria for some or all of the benefits of that position to be recognized in the Company’s financial statements. The Company only recognizes tax positions that meet the more-likely-than-not recognition threshold. (r) Comprehensive Income (Loss) Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as mark-to-market gains or losses of interest rate hedges, are reported as a separate component of the stockholders’ equity section of the balance sheet. Such items, along with net income, are components of comprehensive income (loss). See Notes 1(p), 3, 4 and 6. (2) New Accounting Pronouncements None 46 United States Lime & Minerals, Inc. Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (3) Banking Facilities and Debt The Company’s credit agreement includes a ten-year $40 million term loan (the ‘‘Term Loan’’), a ten-year $20 million multiple draw term loan (the ‘‘Draw Term Loan’’) and a $30 million revolving credit facility (the ‘‘Revolving Facility’’) (collectively, the ‘‘Credit Facilities’’). At December 31, 2013, the Company had $660 thousand of letters of credit issued, which count as draws under the Revolving Facility. Pursuant to a security agreement, dated August 25, 2004, the Credit Facilities are secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property. Under the Credit Facilities, the Company may pay dividends so long as it remains in compliance with the provisions of the Facilities, and may purchase, redeem or otherwise acquire shares of its common stock so long as its pro forma Cash Flow Leverage Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase. The Term Loan requires quarterly principal payments of $833, with a final principal payment of $10.0 million due on December 31, 2015. The Draw Term Loan requires quarterly principal payments of $417, with a final principal payment of $6.7 million due on December 31, 2015. The Revolving Facility matures on June 1, 2015. The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility can be accelerated if any event of default, as defined under the Credit Facilities, occurs. The Revolving Facility commitment fee ranges from 0.250% to 0.400%. In addition, the Credit Facilities bear interest, at the Company’s option, at either LIBOR plus a margin of 1.750% to 2.750%, or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%. The Revolving Facility commitment fee and the interest rate margins are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion and amortization (‘‘EBITDA’’) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. The Company’s maximum Cash Flow Leverage Ratio is 3.25 to 1. The Company has hedges, with Wells Fargo Bank, N.A as the counterparty to the hedges, that fix LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively. Based on the current LIBOR margin of 1.750%, since June 1, 2010 the Company’s interest rates have been: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan. The hedges have been effective as defined under applicable accounting rules. Therefore, changes in fair value of the interest rate hedges are reflected in comprehensive income (loss). The Company will be exposed to credit losses in the event of non-performance by the counterparty to the hedges. Due to interest rate declines, the Company’s mark to market of its interest rate hedges, at December 31, 2013 and December 31, 2012, resulted in liabilities of $1.5 and $2.6 million, respectively, which are included in accrued expenses ($0.9 and $1.1 million, respectively) and other liabilities ($0.6 and $1.5 million, respectively) on the Company’s Consolidated Balance Sheets. The Company paid $1.1 and $1.3 million in aggregate quarterly settlement payments pursuant to the hedges in 2013 and 2012, 47 United States Lime & Minerals, Inc.

The Company’s federal income tax returns for the year ended December 31, 2010 and subsequent years remain subject to examination. The Company’s income tax returns in certain state income tax jurisdictions remain subject to examination for various periods for the year ended December 31, 2010 and subsequent years. The Company treats interest and penalties on income tax liabilities as income taxes. (6) Employee Retirement Plans The Company has a noncontributory defined benefit pension plan (the ‘‘Corson Plan’’) that covers substantially all union employees previously employed by its wholly owned subsidiary, Corson Lime Company. In 1997, the Company sold substantially all of the assets of Corson Lime Company, and all benefits for participants in the Corson Plan were frozen. During 1997 and 1998, the Company made contributions to the Corson Plan that were intended to fully fund the benefits earned by the participants. The unfunded projected benefit obligation is $10 and $290 at December 31, 2013 and 2012, respectively. The Company recorded comprehensive income of $197, net of $112 tax expense, 50 United States Lime & Minerals, Inc. Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (6) Employee Retirement Plans (Continued) $64, net of $36 tax expense and a comprehensive loss of $149, net of $85 tax benefit, for the years ended December 31, 2013, 2012 and 2011, respectively. The Company made contributions of $0, $151 and $18 to the Corson Plan in 2013, 2012 and 2011, respectively. The Company does not expect to make a contribution in 2014. In consultation with the investment advisor for the Corson Plan, the administrative committee, consisting of management employees appointed by the Company’s Board of Directors, establishes the investment objectives for the Plan’s assets. The Plan’s assets are invested using a total return investment approach, whereby a mix of equity securities, debt securities, other investments and cash and cash equivalents are used to preserve asset values, diversify risk and achieve the target investment return benchmark. Investment strategies and asset allocations are based on careful consideration of Plan liabilities and the Plan’s funded status and financial condition. Investment performance and asset allocation are measured and monitored on an ongoing basis. The Corson Plan’s assets are managed in a balanced portfolio composed of two major components: an equity portion and a fixed income portion. The expected role of equity investments is to maximize the long-term real growth of the Plan’s assets, while the role of fixed income investments is to generate current income, provide for more stable periodic returns and provide some protection against a prolonged decline in the market value of equity investments. The current target allocations for Corson Plan assets are 50-70% for equity securities, 25-50% for fixed income securities, 0-15% for other investments and 0-10% for cash and cash equivalents. Equity securities include U.S. and international equity, while fixed income securities include short-duration government agencies and medium-duration bond funds and high-yield bond funds. Other investments include investments in a commodity linked fund and a real estate index fund.

Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (6) Employee Retirement Plans (Continued) The Company expects benefit payments of $122 in 2014, $128 in 2015, $127 in 2016, $128 in 2017, $133 in 2018 and $718 for years 2019-2023. The Company has contributory retirement (401(k)) savings plans for non-union employees and for union employees of Arkansas Lime Company and Texas Lime Company. Company contributions to these plans were $156, $161 and $147 in 2013, 2012 and 2011, respectively. (7) Stock-Based Compensation The Company has implemented the Amended and Restated 2001 Long-Term Incentive Plan (the ‘‘2001 Plan’’). The 2001 Plan provides for stock options, restricted stock and dollar-denominated cash awards, including performance-based awards. In addition to stock options, restricted stock and cash awards, the 2001 Plan provides for the grant of stock appreciation rights, deferred stock and other stock-based awards to directors, officers, employees and consultants. The number of shares of common stock that may be subject to outstanding awards granted under the 2001 Plan (determined immediately after the grant of any award) may not exceed 650,000 from the inception of the 2001 Plan. In addition, no individual may receive awards in any one calendar year of more than 100,000 shares of common stock. Stock options granted under the 2001 Plan expire ten years from the date of grant and generally become exercisable, or vest, over periods of zero to three years from the grant date. Restricted stock generally vests over periods of one-half to five years. Upon the exercise of stock options, the Company issues common stock from its non-issued authorized or treasury shares that have been reserved for issuance pursuant to the 2001 Plan. At December 31, 2013, the number of shares of common stock remaining available for future grants of stock options, restricted stock or other forms of stock-based compensation under the 2001 Plan was 87,202. The Company recorded $934, $1,082 and $848 for stock-based compensation expense related to stock options and shares of restricted stock for 2013, 2012 and 2011, respectively. The amounts included in cost of revenues were $174, $188 and $158, and in selling, general and administrative expense were $760, $894 and $690, for 2013, 2012 and 2011, respectively. A summary of the Company’s stock option and restricted stock activity and related information for the year ended December 31, 2013 and certain other information for the years ended December 31, 2013, 2012 and 2011 are as follows: Weighted- Average Exercise Price Aggregate Intrinsic Value Stock Options Weighted- Average Restricted Grant-Date Fair Value Stock Outstanding (stock options); non-vested (restricted stock) at December 31, 2012 . . . . . . . . . . . . . . . . . .

Total fair value of restricted stock vested during the year . . $ 263 $ 811 $ 559 $ 988 $ 606 $ 715 There were no non-vested stock options at December 31, 2013, and the weighted-average remaining contractual life of the outstanding and exercisable stock options at such date was 6.04 years. The total compensation cost not yet recognized for restricted stock at December 31, 2013 was $853, which will be recognized over the weighted average of 1.05 years. The fair value for the stock options was estimated at the date of grant using a lattice-based option valuation model, with the following weighted-average assumptions for the 2013, 2012 and 2011 grants: risk-free interest rates of 0.34% to 0.77% (weighted average 0.65%) in 2013, 0.36% to 0.51% (weighted average 0.40%) in 2012, and 0.39% to 1.21% (weighted average 0.56%) in 2011; a dividend yield of 0%; and a volatility factor of .304 to .307 (weighted average .306) in 2013, .278 to .288 (weighted average .286) in 2012, and .351 to .411 (weighted average .364) in 2011, based on the monthly per-share closing prices for three years preceding the date of issuance. In addition, the fair value of these options was estimated based on an expected life of three years. The fair value of restricted stock is based on the closing per-share price of the Company’s common stock on the date of grant. (8) Commitments and Contingencies The Company leases some of the equipment used in its operations under operating leases. Generally, the leases are for periods varying from one to five years and are renewable at the option of the Company. The Company also has a lease for corporate office space. Total lease and rent expense was $2.0 million each for 2013 and 2012, and $1.3 million for 2011. As of December 31, 2013, future minimum payments under operating leases that were either non-cancelable or subject to significant penalty upon cancellation were $1,659 for 2014, $1,370 for 2015, $957 for 2016, $333 for 2017, and zero thereafter. The Company is party to lawsuits and claims arising in the normal course of business, none of which, in the opinion of management, is expected to have a material adverse effect on the Company’s financial condition, results of operations, cash flows or competitive position. The Company is not contractually committed to any planned capital expenditures until actual orders are placed for equipment or services. 54 United States Lime & Minerals, Inc. Notes to Consolidated Financial Statements (Continued) (dollars in thousands, except share and per share amounts) Years Ended December 31, 2013, 2012 and 2011 (9) Business Segments The Company has identified two business segments based on the distinctness of their activities and products: lime and limestone operations and natural gas interests. All operations are in the United States. In evaluating the operating results of the Company’s segments, management primarily reviews revenues and gross profit. The Company does not allocate corporate overhead or interest costs to its business segments. Operating results and certain other financial data for the years ended December 31, 2013, 2012 and 2011 for the Company’s two business segments are as follows: 2013 2012 2011 Revenues Lime and limestone operations . . . . . . . . . . . . .

No events have occurred since December 31, 2013 that would have a material effect on the estimated proved reserves. The following information is presented with regard to the Company’s natural gas reserves, all of which are proved and located in the United States. These rules require inclusion, as a supplement to the basic financial statements, of a standardized measure of discounted future net cash flows relating to proved natural gas reserves. The standardized measure, in management’s opinion, should be examined with caution. The basis for these disclosures is independent petroleum engineers’ reserve studies, which contain imprecise estimates of quantities and rates of production of reserves. Revision of estimates can have a significant impact on the results. Also, development and production improvement costs in one year may significantly change previous estimates of proved reserves and their valuation. Values of unproved properties and anticipated future price and cost increases or decreases are not considered. Therefore, the standardized measure is not necessarily a ‘‘best estimate’’ of the fair value of gas properties or of future net cash flows. 56 United States Lime & Minerals, Inc.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE. None ITEM 9A. CONTROLS AND PROCEDURES. Evaluation of disclosure controls and procedures. The Company’s management, with the participation of the Company’s Chief Executive Officer (‘‘CEO’’) and Chief Financial Officer (‘‘CFO’’), evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end of the period covered by this Report. Based on that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures as of the end of the period covered by this Report were effective. MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s CEO and CFO to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. As of December 31, 2013, management assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in the 1992 ‘‘Internal Control—Integrated Framework,’’ issued by the Committee of Sponsoring Organizations of the Treadway Commission (the ‘‘COSO criteria’’). Based on the assessment, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2013, based on the COSO criteria. Grant Thornton LLP, the Company’s independent registered public accounting firm, has issued an audit report on the effectiveness of the Company’s internal control over financial reporting, which appears elsewhere in this Report on Form 10-K. Changes in internal control over financial reporting. No change in the Company’s internal control over financial reporting occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
