UNITED STATES LIME & MINERALS, INC. AND SUBSIDIARIES

Notes to Condensed Consolidated Financial Statements

(Unaudited)

1.Basis of Presentation

The condensed consolidated financial statements included herein have been prepared by United States Lime & Minerals, Inc. (the “Company”) without independent audit.  In the opinion of the Company’s management, all adjustments of a normal and recurring nature necessary to present fairly the financial position, results of operations, comprehensive income and cash flows for the periods presented have been made.  Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) have been condensed or omitted.  These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the period ended December 31, 2012.  The results of operations for the three-month period ended March 31, 2013 are not necessarily indicative of operating results for the full year.

2.Organization

The Company is headquartered in Dallas, Texas, and operates through two business segments.  Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and parking lot 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 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’s Natural Gas Interests segment is held in its wholly owned subsidiary, U.S. Lime Company — O & G, LLC (“U.S. Lime O & G”).  Under a lease agreement (the “O & G Lease”), U.S. Lime O & G has royalty interests ranging from 15.4% to 20% and a 20% non-operating working interest, resulting in an overall average revenue interest of 34.7%, with respect to oil and gas rights in 33 wells drilled and currently producing on the Company’s approximately 3,800 acres of land located in Johnson County, Texas, in the Barnett Shale Formation. Through U. S. Lime O & G, the Company also has a drillsite and production facility lease agreement and subsurface easement (the “Drillsite Agreement”) relating to 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% non-operating working interest, resulting in a 12.4% revenue interest, in the six wells drilled from pad sites located on the Company’s property.

3.Accounting Policies

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.  External freight billed to customers included in first quarter 2013 and 2012 revenues was $6.0 million and $6.8 million, 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.

6

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 and completion 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.

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.  There were no changes in the methods and assumptions used in measuring fair value during the period, which include, as of the valuation date, LIBOR rates over the term of the outstanding debt.  The Company’s financial  liabilities measured at fair value on a recurring basis at March 31, 2013 and December 31, 2012 are summarized below (in thousands):

							Significant Other
							Observable Inputs (Level 2)
	March 31,			December 31,			March 31,			December 31,			Valuation
	2013			2012			2013			2012			Technique
Interest rate swap liabilities	$	(2,335	)	$	(2,629	)	$	(2,335	)	$	(2,629	)	Cash flows approach

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 equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income (loss).

4.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.

The following table sets forth operating results and certain other financial data for the Company’s two business segments (in thousands):

	Quarter Ended

	8,439		9,046
Service parts inventories	5,250		5,081
	$	13,689	$	14,127

8.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 March 31, 2013, the Company had $637 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.

The Term Loan requires quarterly principal payments of $833 thousand, with a final principal payment of $10.0 million due on December 31, 2015.  The Draw Term Loan requires quarterly principal payments of $417 thousand, with a final principal payment of $6.7 million due on December 31, 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%.  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 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%, the Company’s current interest rates are: 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.   The Company’s mark to market of its interest rate hedges, at March 31, 2013 and December 31, 2012, resulted in liabilities of $2.3 million and $2.6 million, respectively, which are included in accrued

9

expenses ($1.1 million for both dates) and other liabilities ($1.3 million and $1.5 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $294 thousand and $339 thousand in the first quarters 2013 and 2012, respectively, in quarterly settlement payments pursuant to the hedges.  These payments are included in interest expense on the Company’s Condensed Consolidated Statements of Operations.

A summary of outstanding debt at the dates indicated is as follows (in thousands):

	March 31,		December 31,
	2013 (1)		2012
Term Loan	$	16,667	$	16,667
Draw Term Loan	10,000		10,000
Revolving Facility (2)	—		—
Subtotal	26,667		26,667
Less current installments	6,250		5,000
Debt, excluding current installments	$	20,417	$	21,667

(1) Because March 31, 2013 was not a business day, the first quarter 2013 $1.25 million repayment on term loan debt was made on April 1, 2013.

(2) The Company had letters of credit totaling $637 issued on the Revolving Facility at both March 31, 2013 and December 31, 2012.

As the Company’s debt bears interest at floating rates, the Company estimates that the carrying values of its debt at March 31, 2013 and December 31, 2012 approximate fair value.

9.Income Taxes

The Company has estimated that its effective income tax rate for 2013 will be approximately 25.4%.  As in prior periods, the primary reason for the effective rate being below the federal statutory rate is due to statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income.

Overview.

The Company has two operating segments:  Lime and Limestone Operations and Natural Gas Interests.  Revenues and gross profit are the primary items utilized to evaluate the operating results of the Company’s segments and to allocate resources.

Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and parking lot 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.  The Lime and Limestone Operations represent the Company’s principal business.

The Company’s Natural Gas Interests are held in its wholly owned subsidiary, U.S. Lime Company — O & G, LLC, and consist of royalty and non-operating working interests under the O & G Lease with EOG Resources, Inc. and the Drillsite Agreement with XTO Energy, Inc. related to the Company’s Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime Company conducts its lime and limestone operations.

Revenues from the Company’s Lime and Limestone Operations decreased 11.1% in the first quarter 2013, compared to the first quarter 2012, primarily because of decreased sales volumes of approximately 11.5% for the Company’s lime and limestone products, principally resulting from the reduction in demand from its steel customers due to the reduction in steel output in the United States and from its oil and gas services customers due to reduced oil and gas drilling activity in the Company’s markets, partially offset by increased sales volumes to its construction customers.  The decreased sales volumes were partially offset by average product price increases of approximately 0.4% realized for the Company’s lime and limestone products in the first quarter 2013, compared to the comparable 2012 quarter.  The Company’s gross profit from its Lime and Limestone Operations

decreased in the first quarter 2013, compared to the first quarter 2012, primarily because of the decrease in revenues in the first quarter 2013, compared to the comparable 2012 quarter.  The Company expects demand from its construction customers will continue to increase in the second quarter 2013 compared to last year’s second quarter, while demand from its steel and oil and gas services customers will continue to be lower.

Revenues from the Company’s Natural Gas Interests decreased in the first quarter 2013 due to lower prices for both natural gas and natural gas liquids, compared to the comparable 2012 quarter, as well as decreased production volumes resulting from the normal declines in production rates on the Company’s existing natural gas wells.  The 32.6% decrease in revenues from Natural Gas Interests in the first quarter 2013, as compared to last year’s comparable quarter, resulted from lower production volumes (approximately 20.7% for the 2013 quarter, compared to the comparable 2012 quarter) and price decreases (approximately 11.9% for the 2013 quarter, compared to the comparable 2012 quarter).  The Company’s gross profit from its Natural Gas Interests decreased for the first quarter 2013, compared to the comparable 2012 quarter, because of the decrease in revenues discussed above.  No new wells were drilled in the first quarter 2013 or are currently being drilled.  The Company cannot predict the number of additional wells that ultimately will be drilled, if any, or their results.

Liquidity and Capital Resources.

Net cash provided by operating activities was $5.4 million in the first quarter 2013, compared to $7.1 million in the first quarter 2012, a decrease of $1.7 million, or 24.3%.  Net cash provided by operating activities is composed of net income, depreciation, depletion and amortization (“DD&A”) and other non-cash items included in net income, and changes in working capital.  In the first quarter 2013, cash provided by operating activities was principally composed of net income of $2.8 million and DD&A of $3.7 million, compared to $4.6 million of net income, $3.6 million of DD&A and $500 thousand of deferred income taxes in the first quarter 2012.  The most significant changes in working capital in the 2013 and 2012 quarters were net increases in trade receivables of $2.2 million and $1.5 million, respectively.  The net increases in trade receivables in the 2013 and 2012 periods primarily resulted from increased revenues in the last month of the first quarters compared to the corresponding last month of the prior year fourth quarters.

The Company had $1.5 million in capital expenditures in the first quarter 2013, compared to $2.3 million in the comparable period last year.

Net cash used in financing activities was $212 thousand and $41.9 million in the 2013 and 2012 quarters, respectively, primarily consisting of $212 thousand and $40.7 million for purchase of treasury shares in the first quarters 2013 and 2012, respectively, and repayment of $1.25 million of term loan debt in the first quarter 2012.  Because March 31, 2013 was not a business day, the first quarter 2013 $1.25 million repayment of term loan debt was made on April 1, 2013.  Cash and cash equivalents increased to $33.5 million at March 31, 2013 from $29.8 million at December 31, 2012.

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 March 31, 2013, the Company had $637 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.

The Term Loan requires quarterly principal payments of $833 thousand, with a final principal payment of $10.0 million due on December 31, 2015.  The Draw Term Loan requires quarterly principal payments of $417 thousand, with a final principal payment of $6.7 million due on December 31, 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.

12

The Revolving Facility commitment fee ranges from 0.250% to 0.400%.  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 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%, the Company’s current interest rates are: 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.  The Company’s mark to market of its interest rate hedges, at March 31, 2013 and December 31, 2012, resulted in liabilities of $2.3 million and $2.6 million, respectively, which are included in accrued expenses ($1.1 million for both dates) and other liabilities ($1.3 million and $1.5 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $294 thousand and $339 thousand in the first quarters 2013 and 2012, respectively, in quarterly settlement payments pursuant to the hedges.  These payments are included in interest expense on the Company’s Condensed Consolidated Statements of Operations.

The Company is not contractually committed to any planned capital expenditures for its Lime and Limestone Operations until actual orders are placed for equipment.  As of March 31, 2013, the Company had no material open orders or commitments that are not included in current liabilities on the March 31, 2013 Condensed Consolidated Balance Sheet.

As of March 31, 2013, the Company had $26.7 million in total debt outstanding and no draws on its $30 million Revolving Facility other than the $637 thousand letters of credit.  The Company believes that cash on hand, cash generated from operations and funds available under the Revolving Facility will be sufficient to meet the Company’s operating needs, ongoing capital needs and debt service for the next 12 months and liquidity needs for the near future.

Results of Operations.

Revenues in the first quarter 2013 decreased to $31.6 million from $36.0 million in the prior year comparable quarter, a decrease of $4.4 million, or 12.3%.  Revenues from the Company’s Lime and Limestone Operations in the first quarter 2013 decreased $3.8 million, or 11.1%, to $30.2 million from $33.9 million in the comparable 2012 quarter, while revenues from the Company’s Natural Gas Interests decreased $693 thousand, or 32.6%, to $1.4 million from $2.1 million in the comparable 2012 quarter.

The decrease in Lime and Limestone Operations revenues in the first quarter 2013 as compared to last year’s comparable quarter primarily resulted from decreased sales volumes of the Company’s lime and limestone products due to decreased demand, principally from its steel and oil and gas services customers, partially offset by increased sales volumes to the Company’s construction customers and a slight increase in prices realized for the Company’s lime and limestone products in the 2013 quarter, compared to the comparable 2012 quarter.  Production volumes for the Company’s Natural Gas Interests for the first quarter 2013 totaled 261 thousand MCF, sold at an average price of

13

$5.49 per MCF.  Production volumes in the comparable prior year quarter were 341 thousand MCF, sold at an average price of $6.23 per MCF.  In the first quarter 2013, the average price per MCF decreased due to lower prices for both natural gas and natural gas liquids contained in the Company’s natural gas, compared to the comparable 2012 quarter.

The Company’s gross profit for the first quarter 2013 was $6.3 million, compared to $9.2 million for the comparable 2012 quarter, a decrease of $2.9 million, or 31.6%.  Included in gross profit for the 2013 quarter was $5.7 million from the Company’s Lime and Limestone Operations, compared to $8.0 million in the comparable 2012 quarter, a decrease of $2.3 million, or 28.7%.  The decrease in gross profit for the Company’s Lime and Limestone Operations in the first quarter 2013 compared to the first quarter 2012 resulted primarily from the decrease in revenues discussed above.  Gross profit from the Company’s Natural Gas Interests was $624 thousand in the first quarter 2013, compared to $1.3 million in the comparable 2012 quarter, a decrease of $628 thousand, or 50.2%, due to the decrease in revenues discussed above.

Selling, general and administrative expenses (“SG&A”) were $2.1 million for the first quarter 2013, compared to $2.3 million for the first quarter 2012, a decrease of $124 thousand, or 5.5%. As a percentage of revenues, SG&A increased to 6.8% in the first quarter 2013, compared to 6.3% in the first quarter 2012. The decrease in SG&A in the 2013 quarter was due to small decreases in numerous components compared to last year’s comparable quarter.

Interest expense in the first quarter 2013 decreased to $489 thousand from $576 thousand in the first quarter 2012, primarily due to decreased average outstanding debt.  Interest expense in the first quarter 2013 included $294 thousand in quarterly settlement payments on the Company’s hedges, compared to $339 thousand of such settlement payments in the comparable 2012 quarter.

Income tax expense was $941 thousand and $1.7 million in the first quarters 2013 and 2012, respectively.  The Company’s effective tax rate was 25.4% and 27.0% in the first quarters 2013 and 2012, respectively. The primary reason that the Company’s effective tax rate is below the federal statutory rate is due to statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income.

The Company’s net income was $2.8 million ($0.50 per share diluted) during the first quarter 2013, compared to net income of $4.6 million ($0.75 per share diluted) during the first quarter 2012, a decrease of $1.9 million, or 40.4%.  First quarter 2013 earnings per share was favorably impacted by $0.06 per share by the Company’s repurchase of 700,000 shares of its common stock in the first quarter 2012, while first quarter 2012 earnings per share was favorably impacted by only $0.01 per share by such repurchase because it occurred late in the quarter.

ITEM 3:QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk.

The Company is exposed to changes in interest rates, primarily as a result of floating interest rates on the Term Loan, Draw Term Loan and Revolving Facility.  At March 31, 2013, the Company had $26.7 million of indebtedness outstanding under floating rate debt. The Company has entered into interest rate hedge agreements to swap floating rates for fixed LIBOR rates at 4.695%, plus the applicable LIBOR margin, through maturity on the Term Loan balance of $16.7 million, 4.875%, plus the applicable LIBOR margin, on $7.5 million of the Draw Term Loan balance and 5.50%, plus the applicable LIBOR margin, on the $2.5 million of the Draw Term Loan balance.  There was no outstanding balance on the Revolving Facility subject to interest rate risk at March 31, 2013.  Any future borrowings under the Revolving Facility would be subject to interest rate risk.  See Note 8 of Notes to Condensed Consolidated Financial Statements.

ITEM 4: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.

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.

PART II.OTHER INFORMATION

ITEM 2:UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The Company’s Amended and Restated 2001 Long-Term Incentive Plan allows employees and directors to pay the exercise price for stock options and the tax withholding liability upon the lapse of restrictions on restricted stock by payment in cash and/or delivery of shares of the Company’s common stock.  In the first quarter 2013, pursuant to these provisions, the Company received 2,007 shares of its common stock for the payment of tax withholding liability upon the lapse of restrictions on restricted stock.  The 2,007 shares were valued at $46.65 per share, the fair market value of one share of the Company’s common stock on the date that they were tendered to the Company.

ITEM 4:  MINE SAFETY DISCLOSURES

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, each operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the SEC.  The operation of the Company’s quarries, underground mine and plants is subject to regulation by the federal Mine Safety and Health Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977.  The required information regarding certain mining safety and health matters, broken down by mining complex, for the quarter ended March 31, 2013 is presented in Exhibit 95.1 to this Report.

The Company believes it is responsible to employees to provide a safe and healthy workplace environment. The Company seeks to accomplish this by: training employees in safe work practices; openly communicating with employees; following safety standards and establishing and improving safe work practices; involving employees in safety processes; and recording, reporting and investigating accidents, incidents and losses to avoid reoccurrence.

Following passage of the Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the enforcement of mining safety and health standards on all aspects of mining operations. There has also been an increase in the dollar penalties assessed for citations and orders issued in recent years.

EXHIBIT 95.1

MINE SAFETY DISCLOSURES

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of SEC Regulation S-K, which require certain disclosures by companies required to file periodic reports under the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”).

The Mine Act has been construed as authorizing MSHA to issue citations and orders pursuant to the legal doctrine of strict liability, or liability without fault. If, in the opinion of an MSHA inspector, a condition that violates the Mine Act or regulations promulgated pursuant to it exists, then a citation or order will be issued regardless of whether the operator had any knowledge of, or fault in, the existence of that condition. Many of the Mine Act standards include one or more subjective elements, so that issuance of a citation or order often depends on the opinions or experience of the MSHA inspector involved and the frequency and severity of citations and orders will vary from inspector to inspector.

Whenever MSHA believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may issue a citation or order which describes the violation and fixes a time within which the operator must abate the violation. In some situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order requiring cessation of operations, or removal of miners from the area of the mine, affected by the condition until the hazards are corrected. Whenever MSHA issues a citation or order, it has authority to propose a civil penalty or fine, as a result of the violation, that the operator is ordered to pay.

The table that follows reflects citations, orders, violations and proposed assessments issued to the Company by MSHA during the quarter ended March 31, 2013 and all pending legal actions as of March 31, 2013. Due to timing and other factors, the data may not agree with the mine data retrieval system maintained by MSHA. The proposed assessments for the quarter ended March 31, 2013 were taken from the MSHA system as of April 29, 2013.

Additional information follows about MSHA references used in the table:

·Section 104(a) Citations: The total number of citations received from MSHA under section 104(a) of the Mine Act for alleged violations of health or safety standards that could significantly and substantially contribute to a serious injury if left unabated.

·Section 104(b) Orders: The total number of orders issued by MSHA under section 104(b) of the Mine Act, which represents a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been abated.

·Section 104(d) Citations and Orders: The total number of citations and orders issued by MSHA under section 104(d) of the Mine Act for unwarrantable failure to comply with mandatory health or safety standards.

·Section 110(b)(2) Violations: The total number of flagrant violations issued by MSHA under section 110(b)(2) of the Mine Act.

·Section 107(a) Orders: The total number of orders issued by MSHA under section 107(a) of the Mine Act for situations in which MSHA determined an imminent danger existed.

Citations and orders can be contested before the Federal Mine Safety and Health Review Commission (the “Commission”), and as part of that process, are often reduced in severity and amount, and are sometimes dismissed.  The Commission is an independent adjudicative agency that provides

administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints of discrimination by miners under section 105 of the Mine Act.

(1)  The definition of a mine under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting from, the work of extracting and processing limestone, such as roads, land, structures, facilities, equipment, machines, tools, kilns, and other property. These other items associated with a single mine have been aggregated in the totals for that mine.

(2)  The proposed MSHA assessments issued during the reporting period do not necessarily relate to the citations or orders issued by MSHA during the reporting period or to the pending contests reported above.

(3)  Includes any pending legal action before the Commission involving such mine as of March 31, 2013. All pending legal actions were initiated by the Company. The pending legal actions may relate to the citations or orders issued by MSHA during the reporting period or to citations or orders issued in prior periods. There were no legal actions instituted or resolved during the reporting period.

Pattern or Potential Pattern of Violations. During the quarter ended March 31, 2013, none of the mines operated by the Company received written notice from MSHA of either (a) a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to mine health or safety hazards under section 104(e) of the Mine Act or (b) the potential to have such a pattern.

The Company is headquartered in Dallas, Texas, and operates through two business segments.  Through its Lime and Limestone Operations, the Company is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and parking lot 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 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’s Natural Gas Interests segment is held in its wholly owned subsidiary, U.S. Lime Company — O & G, LLC (“U.S. Lime O & G”).  Under a lease agreement (the “O & G Lease”), U.S. Lime O & G has royalty interests ranging from 15.4% to 20% and a 20% non-operating working interest, resulting in an overall average revenue interest of 34.7%, with respect to oil and gas rights in 33 wells drilled and currently producing on the Company’s approximately 3,800 acres of land located in Johnson County, Texas, in the Barnett Shale Formation. Through U. S. Lime O & G, the Company also has a drillsite and production facility lease agreement and subsurface easement (the “Drillsite Agreement”) relating to 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% non-operating working interest, resulting in a 12.4% revenue interest, in the six wells drilled from pad sites located on the Company’s property.

Revenue Recognition

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.  External freight billed to customers included in first quarter 2013 and 2012 revenues was $6.0 million and $6.8 million, 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.

Successful-Efforts Method Used for Natural Gas Interests

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 and completion 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.

Fair Values of Financial Instruments

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.  There were no changes in the methods and assumptions used in measuring fair value during the period, which include, as of the valuation date, LIBOR rates over the term of the outstanding debt.  The Company’s financial  liabilities measured at fair value on a recurring basis at March 31, 2013 and December 31, 2012 are summarized below (in thousands):

							Significant Other
							Observable Inputs (Level 2)

Comprehensive Income (Loss)

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 equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income (loss).

8. 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 March 31, 2013, the Company had $637 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.

The Term Loan requires quarterly principal payments of $833 thousand, with a final principal payment of $10.0 million due on December 31, 2015.  The Draw Term Loan requires quarterly principal payments of $417 thousand, with a final principal payment of $6.7 million due on December 31, 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%.  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 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%, the Company’s current interest rates are: 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.   The Company’s mark to market of its interest rate hedges, at March 31, 2013 and December 31, 2012, resulted in liabilities of $2.3 million and $2.6 million, respectively, which are included in accrued expenses ($1.1 million for both dates) and other liabilities ($1.3 million and $1.5 million, respectively) on the Company’s Condensed Consolidated Balance Sheets.  The Company paid $294 thousand and $339 thousand in the first quarters 2013 and 2012, respectively, in quarterly settlement payments pursuant to the hedges.  These payments are included in interest expense on the Company’s Condensed Consolidated Statements of Operations.

A summary of outstanding debt at the dates indicated is as follows (in thousands):

	March 31,		December 31,
	2013 (1)		2012
Term Loan	$	16,667	$	16,667
Draw Term Loan	10,000		10,000
Revolving Facility (2)	—		—
Subtotal	26,667		26,667
Less current installments	6,250		5,000
Debt, excluding current installments	$	20,417	$	21,667

(1) Because March 31, 2013 was not a business day, the first quarter 2013 $1.25 million repayment on term loan debt was made on April 1, 2013.

(2) The Company had letters of credit totaling $637 issued on the Revolving Facility at both March 31, 2013 and December 31, 2012.

As the Company’s debt bears interest at floating rates, the Company estimates that the carrying values of its debt at March 31, 2013 and December 31, 2012 approximate fair value.

9. Income Taxes

The Company has estimated that its effective income tax rate for 2013 will be approximately 25.4%.  As in prior periods, the primary reason for the effective rate being below the federal statutory rate is due to statutory depletion, which is allowed for income tax purposes and is a permanent difference between net income for financial reporting purposes and taxable income.

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.  External freight billed to customers included in first quarter 2013 and 2012 revenues was $6.0 million and $6.8 million, 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.

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 and completion 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.

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.  There were no changes in the methods and assumptions used in measuring fair value during the period, which include, as of the valuation date, LIBOR rates over the term of the outstanding debt.  The Company’s financial  liabilities measured at fair value on a recurring basis at March 31, 2013 and December 31, 2012 are summarized below (in thousands):

							Significant Other
							Observable Inputs (Level 2)
	March 31,			December 31,			March 31,			December 31,			Valuation
	2013			2012			2013			2012			Technique
Interest rate swap liabilities	$	(2,335	)	$	(2,629	)	$	(2,335	)	$	(2,629	)	Cash flows approach

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 equity section of the balance sheet.  Such items, along with net income, are components of comprehensive income (loss).
