The information in this section is not complete and does not contain all of the information that you should consider before exercising your subscription rights. You should read the entire prospectus carefully, including the "Risk Factors" section and the documents listed under "If You Would Like More Information." QUESTIONS AND ANSWERS ABOUT UNITED STATES LIME & MINERALS WHAT IS UNITED STATES LIME & MINERALS, INC.? United States Lime & Minerals was incorporated in 1950. Our business is the production and sale of lime and limestone products. We extract high-quality limestone from our quarries and process it for sale as pulverized limestone, quicklime, and hydrated lime. We conduct our operations at three wholly-owned subsidiaries: Arkansas Lime Company, Texas Lime Company, and Colorado Lime Company. WHERE ARE WE LOCATED? Our principal executive offices are located at: United States Lime & Minerals, Inc. 13800 Montfort Drive, Suite 330 Dallas, Texas 75240 QUESTIONS AND ANSWERS ABOUT THE RIGHTS OFFERING WHAT IS A RIGHTS OFFERING? A rights offering is an opportunity for you to purchase additional shares of common stock at a fixed price and in an amount proportional to your existing interest, which enables you to maintain and possibly increase your current percentage ownership. WHAT IS A SUBSCRIPTION RIGHT? We are distributing to you, at no charge, [ ] subscription rights for every share of common stock that you owned on [November ], 2000. We will not distribute any fractional subscription rights, but will round the number of subscription rights you receive down to the nearest whole number. Each subscription right entitles you to purchase one share of common stock for $[ ]. When you "exercise" a subscription right, that means that you choose to purchase the number of shares of common stock that each subscription right entitles you to purchase. You may exercise any number of your subscription rights, or you may choose not to exercise any subscription rights. You cannot give or sell your subscription rights to anybody else -- only you can exercise them. See "About the Rights Offering -- The Subscription Rights." WHAT IS THE BASIC SUBSCRIPTION PRIVILEGE? The basic subscription privilege of each subscription right entitles you to purchase one share of our common stock at a subscription price of $[ ]. See "About the Rights Offering -- Basic Subscription Privilege." WHAT IS THE OVER-SUBSCRIPTION PRIVILEGE? We do not expect that all of our shareholders will exercise all of their basic subscription privileges. By extending over-subscription privileges to our shareholders, we are providing for the purchase of those shares which are not purchased through exercise of basic subscription privileges. The over-subscription privilege of each subscription right entitles you, if you fully exercise your basic subscription privilege, at the same time to subscribe for additional shares of common stock at a subscription price of $[ ] per share. See "About the Rights Offering -- Over-Subscription Privilege." 1 5 WHAT ARE THE LIMITATIONS ON THE OVER-SUBSCRIPTION PRIVILEGE? If sufficient shares are available, we will honor the over-subscription requests in full. If over-subscription requests exceed the number of shares available, we will allocate all or a portion of the available shares among shareholders who over-subscribed in proportion to the number of shares purchased by those over-subscribing shareholders through the exercise of their basic subscription privilege. Inberdon Enterprises has expressed its willingness not to subscribe for shares pursuant to the over-subscription privilege. See "About the Rights Offering -- Over-Subscription Privilege." WHY ARE WE ENGAGING IN A RIGHTS OFFERING? We are offering the subscription rights to obtain additional equity capital which, together with increased bank borrowings (see "Banking Facilities"), should enable us to construct Phase II of the Arkansas expansion and modernization project ("Arkansas Phase II"), and provide us with ongoing working capital. Any excess funds will be utilized for general corporate purposes. We have intended to finance Arkansas Phase II through a combination of internally generated funds, additional bank borrowings, and/or other sources of capital. Given the lower than expected operating income generated in the second and third quarters of this year, as well as the increased costs of the Arkansas project, our Board has determined to seek to raise additional equity capital through this rights offering to our existing shareholders, and to seek an additional seven-year, $7,000,000 term loan, which is conditioned on our raising at least $5,000,000 in new equity. Our Board has chosen to give existing shareholders the opportunity to buy more shares to provide us with additional equity, rather than selling additional shares of common stock to others. Of course, we cannot assure you that we will not need to seek additional financing in the future. See "Risk Factors -- Capital Requirements; Uncertainty of Additional Funding." HOW MANY SHARES MAY I PURCHASE? You will receive [ ] subscription rights for each share of common stock that you owned on [November ], 2000. We will not distribute fractional subscription rights, but will round the number of subscription rights you are to receive down to the nearest whole number. Each subscription right entitles you to purchase one share of common stock for $[ ]. See "About the Rights Offering -- Basic Subscription Privilege." If you exercise all of the subscription rights that you receive, you may have the opportunity to purchase additional shares of common stock. On the attached subscription certificate, you may request to purchase as many additional shares as you wish for $[ ] per share. We may honor all of these over-subscription requests, but if not, you may not be able to purchase as many shares as you requested on your subscription certificate. Subject to state securities laws and regulations, we have the discretion to issue less than the total number of shares that may be available for over-subscription requests in order to comply with state securities laws. See "About the Rights Offering -- Over-Subscription Privilege." HOW DID WE ARRIVE AT THE $[ ] PER SHARE PRICE? Our Board of Directors, excluding the director affiliated with Inberdon, set all of the terms and conditions of the rights offering, including the price per share. In determining the price per share during the rights offering, our Board of Directors, excluding the director affiliated with Inberdon, considered several factors, including the current and historical market prices of the common stock, our book value per share, our business prospects, general conditions in the securities market, our need for capital, alternatives available to us for raising capital, the amount of proceeds desired, pricing of similar transactions, the liquidity of our common stock, the level of risk to our shareholders, and the need to offer shares at a price that would be acceptable to Inberdon and attractive to our other shareholders relative to the current trading price of our common stock. See "About the Rights Offering -- Determination of Subscription Price." 2 6 HOW DO I EXERCISE MY SUBSCRIPTION RIGHTS? You must properly complete the attached subscription certificate and deliver it to the Subscription Agent before 5:00 p.m., Eastern Standard Time on [ ], 2000. The address for the Subscription Agent is on page 18. See "About the Rights Offering -- Exercise of Subscription Rights." HOW DO I PAY FOR MY SHARES? Your subscription certificate must be accompanied by proper payment for each share that you wish to purchase pursuant to both your basic and over-subscription privileges. See "About the Rights Offering -- Method of Payment." HOW LONG WILL THE RIGHTS OFFERING LAST? You will be able to exercise your subscription rights only during a limited period. IF YOU DO NOT EXERCISE YOUR SUBSCRIPTION RIGHTS BEFORE 5:00 P.M., EASTERN STANDARD TIME, ON [ ], 2000, THE SUBSCRIPTION RIGHTS WILL EXPIRE. We may, in our discretion, decide to extend the rights offering. In addition, if the commencement of the rights offering is delayed, the expiration date will similarly be extended. See "About the Rights Offering -- Expiration Date." WHAT IF MY SHARES ARE NOT HELD IN MY NAME? If you are a beneficial owner of common stock held by a holder of record, such as a broker, trustee or a depository for securities, you should contact the holder and ask him or her to effect transactions in accordance with your instructions. Notwithstanding the above, if you are a current or former employee of ours who beneficially owns shares of our common stock which are held in our 401(k) plan (formerly the ESOP), we will treat those shares as part of your record ownership for purposes of calculating your subscription rights. See "About the Rights Offering -- Shares Held for Others." AFTER I EXERCISE MY SUBSCRIPTION RIGHTS, CAN I CHANGE MY MIND? No. Once you send in your subscription certificate and payment, you cannot revoke the exercise of your subscription rights, even if you later learn information about us that you consider to be unfavorable. You should not exercise your subscription rights unless you are certain that you wish to purchase additional shares of common stock at a price of $[ ] per share. See "About the Rights Offering -- No Revocation." IS EXERCISING MY SUBSCRIPTION RIGHTS RISKY? The exercise of your subscription rights involves various risks. Exercising your subscription rights means buying additional shares of our common stock and should be carefully considered as you would view any other equity investment. Among other things, you should carefully consider the risks described under the heading "Risk Factors," beginning on page 6. WHAT HAPPENS IF I CHOOSE NOT TO EXERCISE MY SUBSCRIPTION RIGHTS? You will retain your current number of shares of common stock even if you do not exercise your subscription rights. However, if other shareholders exercise their subscription rights and you do not, the percentage of United States Lime & Minerals that you own will diminish, and your voting and other rights will be diluted. See "Risk Factors -- Dilution of Your Percentage Ownership of United States Lime & Minerals, Inc." CAN I SELL OR GIVE AWAY MY SUBSCRIPTION RIGHTS? No. 3 7 MUST I EXERCISE ANY SUBSCRIPTION RIGHTS? No. WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF EXERCISING MY SUBSCRIPTION RIGHTS? The receipt and exercise of your subscription rights are intended to be nontaxable. You should seek specific tax advice from your personal tax advisor. See "Federal Income Tax Considerations -- Taxation of Shareholders." WHEN WILL I RECEIVE MY NEW SHARES? If you purchase shares of common stock through the rights offering, you will receive certificates representing those shares as soon as practicable after [ ], 2000. CAN WE CANCEL THE RIGHTS OFFERING? Yes. The Board of Directors, excluding the director affiliated with Inberdon, may cancel the rights offering at any time, on or before [ ], 2000, for any reason. If we cancel the rights offering, any money received from shareholders will be refunded promptly. See "About the Rights Offering -- Cancellation Right." HOW MUCH MONEY WILL UNITED STATES LIME & MINERALS RECEIVE FROM THE RIGHTS OFFERING? Our gross proceeds from the rights offering depend on the number of shares that are purchased. If we sell all [ ] shares offered by this prospectus, then we will receive proceeds of $10,000,000. To guarantee us $10,000,000 in proceeds from the rights offering, our majority shareholder, Inberdon, has expressed its willingness to exercise its basic subscription rights in full, and if the rights offering is undersubscribed, to purchase the remainder of the shares that are not fully subscribed for by other shareholders. Additionally, Inberdon has expressed its willingness not to subscribe for shares pursuant to its over-subscription privilege, thus stepping back to allow other fully subscribing shareholders to purchase additional shares if they wish. Upon completion of the rights offering, Inberdon will own between 51% and [ ]% of our outstanding common stock depending on whether other shareholders exercise their subscription rights. As a result of Inberdon's willingness to backstop the rights offering, we expect to receive proceeds of $10,000,000 from the rights offering, even if no other shareholders exercise their rights. See "About the Rights Offering -- Purchase Commitments." HOW WILL WE USE THE PROCEEDS FROM THE RIGHTS OFFERING? We will use the proceeds from the rights offering, together with increased bank borrowings, to provide $5,000,000 in additional equity capital for use in the construction of Arkansas Phase II and additional working capital. Any excess will be used for general corporate purposes. See "Use of Proceeds." HOW MANY SHARES WILL BE OUTSTANDING AFTER THE RIGHTS OFFERING? The number of shares of common stock that will be outstanding after the rights offering depends on the number of shares that are purchased. If we sell all of the shares offered by this prospectus, then we will issue [ ] new shares of common stock during the rights offering. In that case, we will have approximately [ ] shares of common stock outstanding after the rights offering. Even if no other shareholders exercise their subscription rights, Inberdon has expressed its willingness to purchase all [ ] shares of common stock from us in the rights offering, in which case we will have approximately [ ] shares of common stock outstanding after the rights offering. 4 8 WHAT IF I HAVE MORE QUESTIONS? If you have more questions about the rights offering, please contact our Vice President of Finance, Corporate Controller and Secretary, Larry T. Ohms, 13800 Montfort Drive, Suite 330, Dallas, Texas 75240, Telephone: 972-991-8400. See "If You Have Questions." A WARNING ABOUT FORWARD-LOOKING STATEMENTS Any statements contained in this prospectus that are not statements of historical fact are forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. Forward-looking statements in this prospectus, including without limitation, statements relating to our plans, strategies, objectives, expectations, intentions, and adequacy of resources, are identified by such words as "will," "could," "should," "believe," "expect," "intend," "plan," "schedule," "estimate," and "project." We undertake no obligation to publicly update or revise any forward-looking statements. You are cautioned that forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from expectations, including without limitation the following: (i) our plans, strategies, objectives, expectations, and intentions are subject to change at any time at our discretion; (ii) our plans and results of operations will be affected by our ability to manage our growth and modernization; and (iii) other risks and uncertainties set forth below or indicated from time to time in our filings with the Securities and Exchange Commission. 5 9 RISK FACTORS Investing in United States Lime & Minerals' common stock involves certain risks. You should be able to bear a complete loss of your investment. You should carefully consider the following factors and other information in this prospectus before deciding to invest in, or make further investments in, our common stock. RISKS ASSOCIATED WITH THE OFFERING OF SUBSCRIPTION RIGHTS Dilution of your percentage ownership of United States Lime & Minerals. If you do not exercise all of your subscription rights, you may suffer significant dilution of your percentage ownership of United States Lime & Minerals relative to shareholders who exercise their subscription rights. For example, if you own [ ] shares of common stock before the rights offering, or [ ]% of the equity of United States Lime & Minerals, and you exercise none of your subscription rights while all other subscription rights are exercised through the basic subscription privilege or over-subscription privilege, then your percentage ownership will be reduced to [ ]%. Risks associated with exercising subscription rights. We cannot assure you that the public trading market price of our common stock will not decline before the subscription rights expire. If you exercise your subscription rights and then the public trading market price of the common stock decreases below $[ ], then you will have committed to buy shares of common stock at a price above the prevailing market price. Moreover, we cannot assure you that following the exercise of subscription rights you will be able to sell your shares of common stock at a price equal to or greater than the subscription price. Until certificates are delivered upon expiration of the rights offering, you may not be able to sell the shares of our common stock that you purchase in the rights offering. Certificates representing shares of our common stock that you purchased will be delivered as soon as practicable after expiration of the rights offering. We will not pay you interest on funds delivered to the Subscription Agent pursuant to the exercise of rights. No revocation of exercise of subscription rights. Once you exercise your subscription rights, you may not revoke the exercise. Cancellation of rights offering. If we elect to cancel the rights offering, neither we nor the Subscription Agent will have any obligation with respect to the subscription rights except to return, without interest, any subscription payments. Determination of the subscription price. Our Board of Directors, excluding the director affiliated with Inberdon, set all of the terms and conditions of the rights offering, including the subscription price. The subscription price does not necessarily bear any relationship to the book value of our assets, past operations, cash flows, financial condition or any other established criteria for value. You should not consider the subscription price as an indication of the value of United States Lime & Minerals or our common stock. See "About the Rights Offering -- Determination of Subscription Price." Volatility of stock price. Based on the trading history of our common stock, we believe that certain factors cause the market price of our stock to fluctuate significantly. These factors include, without limitation: - quarterly fluctuations in our financial results; - general economic conditions and the impact of government programs such as the Transportation Equity act for the 21st Century; - market conditions in the lime industry, and in the industries that purchase our products; - changes in relationships with our customers; and - the size of the public float of our common stock (which will depend, in part, on the number of shares of common stock purchased or acquired by you and other shareholders in the rights offering). 6 10 Control by major shareholder. As of [November ], 2000, Inberdon owned approximately [51]% of our voting stock. The rights offering could, and in fact is likely to, result in Inberdon owning an even greater percentage of our common stock. Inberdon has enough votes to approve or disapprove any matters that are determined by a majority vote of our shareholders, and accordingly your ability to influence United States Lime & Minerals through voting your shares is limited. RISK FACTORS RELATING TO UNITED STATES LIME & MINERALS Existing and future adverse effects of leverage and restrictions imposed by terms of our indebtedness. Following the closing of this offering and the New Loan (see "Banking Facilities -- New Debt") facility our debt ratio is expected to have improved (see "About the Rights Offering -- Capitalization Table"), although the total debt may be greater than it has been to date. The greater total debt may mean that a substantial portion of our cash flows from operations may be dedicated to the payment of principal and interest on indebtedness. Our ability to service our debt and to comply with the financial and restrictive covenants contained in our loan agreements will depend upon our future performance and business growth. Performance and growth, in turn, are subject to financial, economic, competitive, and other factors. Many of these factors are beyond our control. In particular, our ability to service our indebtedness will depend upon our ability to generate higher levels of revenues and cash flows through the modernization and expansion of the Texas and Arkansas plants. While we believe that we will be able to generate sufficient cash flow to cover our current and anticipated future debt service payments, we cannot provide any assurance to that effect. Compliance with environments laws and regulations. Our operations are subject to various federal, state, and local environmental laws and regulations, including the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act, and the Comprehensive Environmental Response, Compensation, and Liability Act, as well as the Toxic Substances Control Act. The rate of change of such legislation has been rapid over the last decade, and compliance can require significant expenditures. For example, recent federal legislation required Texas Lime Company and Arkansas Lime Company to apply for "Title V" renewable operating permits ("Operating Air Permits") which have significant on-going compliance monitoring costs. While we cannot be certain that we will always be able to comply with changing requirements without a material impact on our business, we are not aware of any such impending change. In September 1999, we received an Operating Air Permit for Phase I of the modernization and expansion project for the Arkansas facility. In June 2000, we received a second Operating Air Permit for Arkansas Phase II. These permits cover air emissions generated at the facility and contain stringent emission limits and performance criteria that the new rotary lime kilns and plant must meet. Until both kilns are fully operational and have demonstrated their ability to comply with the permit conditions, there can be no assurance that additional capital will not be required, or operating conditions imposed, in order to achieve compliance. Completion of Phase II of the Arkansas expansion. The construction of the Arkansas project could also have a material adverse effect on our business or financial results due to the impact of start-up costs and the potential for under-utilization, especially in the start-up phase. No assurance can be given that the expansion of the Arkansas facility will be completed on time or within current budget projections, and may be abandoned due to these or other issues. Further, we cannot guarantee that we will be able to sell our products, or reestablish accounts with those customers that previously purchased products from Arkansas Lime, once increased production has commenced, or that any such sales will be profitable. We may be required to obtain additional debt financing should the actual costs of the Arkansas project exceed our available funds. We may decide to incur additional debt or issue additional equity securities to pay for construction or other expansion costs, which could have a further material adverse dilutive effect on the ownership interests of our current stockholders. Competition. The lime industry is highly regionalized and competitive. Our competitors include both public and private companies. The primary competitive factors in the lime industry are quality, price, 7 11 proximity to the customer, 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 business could be materially adversely affected. Although demand for lime has been relatively strong in recent years, we are unable to predict future demand and prices, and we cannot provide any assurance that current levels of demand and pricing will continue or that any future price increases can be sustained. Industry consolidation. There is a continuing trend of consolidation in the lime and limestone industry. Currently, the four largest lime companies in North America account for approximately 70% of total lime capacity. In addition to, and often in conjunction with, consolidations, many producers have undergone modernization and expansion projects to upgrade their processing equipment in an effort to improve their operating efficiency and competitive position. As industry consolidation continues, we will continue to evaluate external opportunities for expansion, as well as pursue our modernization and expansion projects, in an effort to remain competitive, protect our markets, and position ourself for the future. We cannot provide any assurance that we will have sufficient financial and management resources to implement our strategy, particularly while we are endeavoring to complete the Arkansas project. Therefore, we may be required to revise our strategy, or otherwise find ways to enhance our value for stockholders, including by entering into strategic partnerships, mergers, or other transactions that may result in a change of control of our company. RECENT DEVELOPMENTS During the first nine months of 2000, our operating results have been adversely affected by a number of factors, which include rapidly increasing fuel costs, particularly natural gas, lower sales of pulverized limestone used in roofing products, and unprecedented flooding at the Texas Lime Company in June. Actions have been taken to mitigate these adverse factors which, together with the new production facilities under construction, should significantly improve net income in 2001. The high natural gas cost has impacted the results of Arkansas Lime Company, increasing operating losses because the old vertical kilns could only burn gas. The new Phase I rotary kiln, which began operation on October 22, 2000, has resolved this issue because it is permitted to burn coal or coke, and the old kilns were permanently closed on October 20, 2000, one month later than originally estimated. At Texas Lime Company, multi-fuel options are permitted, and coal has now been substituted for gas to the greatest extent possible. The June flooding in Texas was the result of exceptional rainfall, subsequently confirmed by the National Weather Service to be the heaviest monthly total in the area for 113 years. The floods caused a significant loss of production, the depletion of finished goods inventories, and lead to increased costs through purchasing lime from outside sources to fulfill customer commitments. There was no long-term damage, and the plant was back in full production in July. We have retained our customer base and expect to rebuild to the normal level of finished goods inventories before the fiscal year-end. Inclement weather on this scale is unusual, and we have completed considerable site work to minimize the impact of similar events, should they occur. At the beginning of the fourth quarter 2000, we commissioned a new line for the production of pulverized limestone at Texas Lime Company. At a cost of $1.8 million, this investment will allow us to pursue new business opportunities and better serve existing customers. The lack of reliability of a single production line was a restraining factor on sales to several large customers requiring 'round-the-clock' availability. The production operations at Texas Lime are highly integrated, and increasing the level of pulverized limestone production along with the recent increases in lime capacity, allows for a lower level of production cost to be achieved. We now estimate that total capital expenditures for Phase I of the Arkansas project will be approximately $30,000,000, approximately $1,300,000 over the estimate stated in our second quarter 2000 Form 10-Q of $28,700,000. This total includes an increased scope of work, the benefit of which will be to 8 12 reduce future operating costs, and also includes approximately $1,000,000 of costs incurred for certain facilities that were pre-built for Phase II of the project, as it was cost-effective to construct those facilities concurrently with Phase I. In addition, the increased costs of Phase I reflect additional construction costs from delayed completion of certain facilities, as well as our reduced ability to attract competitive bids for the later stages of the project due to the continued high level of construction activity in the area. Arkansas Phase II is estimated to cost approximately $12,000,000. However, we have determined to delay the start of Arkansas Phase II, and currently plan to commence construction in mid-year 2001, subject to market demand, ability to secure competitive bids, and the availability of financing. We have intended to finance Arkansas Phase II through a combination of internally generated funds, additional bank borrowings, and/or other sources of capital. Given the lower than expected operating income generated in the second and third quarters of this year, as well as the increased costs of the Arkansas project, our Board of Directors has determined to seek to raise additional equity capital through this rights offering to our existing shareholders, and to seek an additional seven-year, $7,000,000 term loan, which is contingent on our raising at least $5,000,000 in new equity. In the Board's view, the additional financings will enable us to proceed with Phase II of the Arkansas project, and provide us with ongoing working capital. In the view of our Board, we should proceed with Arkansas Phase II in order to achieve maximum utilization of the infrastructure completed there to date, thus maximizing our rate of return on that investment, by approximately doubling the capacity of the Arkansas plant for an incremental investment of approximately $12,000,000. BANKING FACILITIES EXISTING DEBT We have a $50,000,000 Senior Secured Term Loan (the "Loan"), provided by a consortium of commercial banks, which was fully drawn down on March 30, 2000. The Loan was used to repay all existing bank loans, with the balance principally used to fund Phase I of the Arkansas project. Monthly principal payments of $277,778 began on April 30, 2000, and will terminate on March 30, 2007, when a final payment of $26,944,444 is due. The interest rate is fixed at a weighted average rate of 9.135%, in addition to which, we pay a servicing fee of 0.125% of the outstanding principal. The Loan is secured by a first lien on substantially all of our assets with the exception of accounts receivable and inventories. We also have a $4,000,000 revolving credit facility (the "Revolver") provided by the lead bank of the Loan consortium and secured by accounts receivable and inventories. The Revolver bears interest at LIBOR plus 1.40%, which rate will increase in accordance with a defined rate spread based upon our then-current rate of total funded debt to earnings before interest, taxes, depreciation and amortization (EBITDA). The Revolver expires on April 20, 2001, and at October 31, 2000, we had not drawn down any funds under this facility, but we anticipate drawing down the full amount by January 31, 2001 because of the impact of increased construction costs, higher start-up costs, and lower than expected operating income. NEW DEBT We have received the support in principle of our lead bank to provide an additional seven-year, $7,000,000 term loan facility to be used for the Arkansas Phase II (the "New Loan"). The bank has issued a draft term sheet for the New Loan which contains certain conditions precedent to be met before the funds can be advanced. We believe that we will be able to satisfy these conditions precedent; however, there can be no guarantee of this and, if we are unable to do so, then the Company may have to seek alternative sources of financing to complete Arkansas Phase II. The principal terms and conditions of the proposed New Loan are: - we must raise a minimum of $5,000,000 of new equity capital, net of costs, concurrently with, or prior to, the closing of the New Loan; 9 13 - the consortium of banks that provided the Loan must consent to a second mortgage on the Arkansas facility and certain other amendments to the security and intercreditor agreements; and - the New Loan is expected to bear interest at the rate of LIBOR plus 3.0% per annum with a seven-year amortization of principal. Interest only will be payable during the first twelve months of the facility. ABOUT UNITED STATES LIME & MINERALS United States Lime & Minerals, Inc. was incorporated in 1950. Our business is the production and sale of lime and limestone products. We extract high-quality limestone from our quarries and process it for sale as pulverized limestone, quicklime, and hydrated lime. We conduct our operations through three wholly-owned subsidiaries: Arkansas Lime Company, Texas Lime Company, and Colorado Lime Company. We extract raw limestone and then processes it for sale as pulverized limestone, quicklime, and hydrated lime. Pulverized limestone, also referred to as ground calcium carbonate, is a dried product 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 to produce a dry, white powder. Pulverized limestone is used primarily in the production of construction materials such as asphalt paving and roofing shingles, as an additive to agriculture feeds, as a soil enhancement, and for mine safety dust in coal mining operations. Quicklime is used primarily in the manufacturing of paper products, in sanitation and water filtering systems, in metal processing, and in soil stabilization for highway and building construction. Hydrated lime is used primarily in municipal sanitation and water treatment, in soil stabilization for highway and building construction, in the production of chemicals, and in the production of construction materials such as stucco, plaster and mortar. Our principal customers for lime and limestone products are highway, street and parking lot contractors, chemical producers, paper manufacturers, roofing shingle manufacturers, steel producers, glass manufacturers, municipal sanitation and water treatment facilities, poultry and cattle feed producers, governmental agencies, and electric utility companies. We transport our lime and limestone products by rail and truck to customers generally within a radius of 400 miles of each of our processing plants. Substantially all of our sales are made within the United States, with a majority of our product sales occurring in the states of Arkansas, Colorado, Kansas, Louisiana, Mississippi, Missouri, New Mexico, Oklahoma, Tennessee, and Texas. Approximately 700 customers accounted for our sales of lime and limestone products during the year ended December 31, 1999. No single customer accounted for more than 10% of such sales. We are not subject to significant customer risks because our customers are considerably diversified as to geographic location and industrial concentration. However, given the capital intensive nature of the lime and limestone industry, our profits are very sensitive to changes in sales volume. Our sales have historically reflected seasonal trends, with the largest percentage of total annual revenues 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. Two of our subsidiaries currently extract limestone from open-pit quarries: the Texas Lime Company, which is located 14 miles from Cleburne, Texas; and the Arkansas Lime Company, which is located near Batesville, Arkansas. A third subsidiary, the Colorado Lime Company, owns limestone resources at Monarch Pass located 15 miles west of Salida, Colorado. Texas Lime Company operates upon a tract of land containing approximately 470 acres, including the Cleburne Quarry. In January 1999, we purchased approximately 400 acres of additional land and now own approximately 2,700 acres adjacent to the quarry. Both the quarry and the adjacent land contain known 10 14 high-quality limestone reserves in a bed averaging 28 feet in thickness, with an overburden that ranges from 0 to 50 feet. We also have mineral interests in approximately 560 acres of land adjacent to the northwest boundary of that property. The calculated reserves, as of January 31, 1999, were approximately 44,000,000 tons of proven reserves and approximately 91,000,000 tons of probable reserves. Assuming the enhanced level of production following the Texas modernization and expansion project is maintained, we estimate that these reserves are sufficient to sustain operations for approximately 100 years. Arkansas Lime Company operates the Batesville Quarry and has lime and limestone production facilities on a second site linked to the quarry by its own light-gauge railroad. The active quarry operations cover approximately 725 acres of land containing a known deposit of high-quality limestone. The average thickness of the high-quality limestone deposit is approximately 70 feet, with an average overburden thickness of 35 feet. We also own approximately 325 additional acres containing additional high-quality limestone deposits adjacent to the present quarry but separated from it by a public highway. The average thickness of this second high-quality limestone deposit is approximately 55 feet, with an average overburden of 20 feet. The calculated reserves, as of January 31, 1999, were approximately 23,500,000 tons of proven reserves plus an additional 33,500,000 tons of probable reserves. Assuming the present level of production is maintained, we estimate that reserves are sufficient to sustain operations for approximately 100 years. However, this estimate is reduced to 50 years assuming that the Arkansas facility reaches projected production levels after the planned modernization and expansion. Colorado Lime Company 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, we do not consider the cost of a drilling program to be economically feasible at this time and, consequently, it is not possible to identify and categorize reserves. The Monarch Pass Quarry, which had been operated for many years until its closure in the early nineties, contains a mixture of limestone types, including high-quality calcium limestone and dolomite. We expect to utilize remaining crushed stone inventories to supply our processing plant in nearby Salida. Developed quarry benches are available and will be mined if the need arises. We extract limestone by the open-pit method at the Arkansas and Texas quarries. Monarch Pass is also an open-pit quarry, but is not being worked at this time. 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. After extraction through mining operations, limestone is crushed, screened, and ground in the case of pulverized limestone, or further processed in kilns and hydrators in the case of quicklime and hydrated lime, before shipment. We produce lime and/or limestone products at three plants as described below. Following the completion of the modernization and expansion of the Texas plant at the end of 1998, the annual capacity is now 470,000 tons of quicklime from three rotary kilns. The Texas project included the installation of a new stone crushing and handling system, the addition of a preheater to one of the existing kilns, additional storage, screening, and shipping capacity, and a new support building housing a laboratory and administrative and shop facilities. The plant has pulverized limestone equipment which has a capacity to produce 700,000 tons of pulverized limestone annually, depending on the product mix, however, construction of a second pulverizing line is in progress which is intended to provide operational flexibility in addition to an increase in capacity to approximately 1,000,000 tons per annum. In addition to the Cleburne plant, we own a dormant plant which is located near Blum, Texas on a tract of land covering approximately 40 acres. The Blum plant was acquired in 1989, and its kilns have not been operated since that time; however, the plant's storage and shipment facilities are currently being utilized. The Arkansas Lime production plant is situated on a tract of 290 acres located approximately two miles from the Batesville Quarry to which it is connected by a company-owned light-gauge railroad. Utilizing six vertical kilns, this plant has an annual capacity of 85,000 tons of quicklime. The plant has two grinding systems which, depending on the product mix, have the capacity to produce 700,000 tons of pulverized limestone annually. 11 15 Over the past decade, Arkansas Lime Company has lost various accounts due to poor product quality and service from the vertical lime kilns which were installed in the 1920's. We have commenced a modernization and expansion of the Arkansas facility, to be completed in two phases, which is designed to expand production and improve quality and service, enabling Arkansas Lime Company to compete for new accounts and accounts with former customers lost due to the quality and service issues. Phase I includes the redevelopment of the quarry plant, rebuilding of the railroad to standard United States gauge, establishment of an out-of-state terminal, and installation of a rotary kiln with preheater, along with increased product storage and loading capacity. Completion of Phase I will provide us with a modern quarry and lime manufacturing facilities with an annual production capacity of up to approximately 200,000 tons of quicklime. A distribution facility in Shreveport, Louisiana, connected to the Kansas City Southern railroad, is in the process of being completed to provide lime storage and distribution capacity to service markets in Louisiana and East Texas. Arkansas Phase II will further expand lime production capacity at Arkansas to approximately 400,000 tons of quicklime by the installation of a second rotary kiln and preheater with additional storage capacity. We maintain lime hydrating equipment and limestone drying and pulverizing equipment at both the Texas and Arkansas plants. Storage facilities for lime and pulverized limestone products at each plant consist primarily of cylindrical tanks, which we considered to be adequate to protect our lime and limestone products and to provide an available supply for our customers' needs at the existing volume of shipments. Equipment is maintained at each plant to load trucks, and at the Arkansas and Blum plants to load railroad cars. The Colorado Lime Company operates a limestone drying, grinding and bagging facility, with an annual capacity of 60,000 tons, on 99 acres of land in Salida, Colorado. The property is leased from the Union Pacific Railroad for a term of 5 years, commencing June 1999, with renewal options for a further 10 years. A rail loading spur is available, although we do not currently ship any products by rail from this facility. This plant's facilities also include a small rotary lime kiln which is permitted for operation but is presently not being operated. A mobile stone crushing and screening plant is situated in the Monarch Pass Quarry, producing agricultural grade limestone, with an annual capacity of up to 40,000 tons. ABOUT THE LIME INDUSTRY In recent years, the demand for lime has been relatively strong, and price levels have gradually increased. However, the industry remains localized and competitive, with quality, price and proximity to customers being the prime factors affecting competition. Our competitors are predominately private companies, and, following a period of substantial consolidation in the lime and limestone industry, with the four largest lime companies now account for approximately 70% of North American lime 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. Our modernization and expansion projects should allow us to continue to remain competitive, protect our markets, and position ourselves for the future. In addition, we will continue to evaluate external opportunities for expansion. ABOUT THE RIGHTS OFFERING BEFORE EXERCISING ANY SUBSCRIPTION RIGHTS, YOU SHOULD READ CAREFULLY THE INFORMATION SET FORTH UNDER "RISK FACTORS" BEGINNING ON PAGE 6. THE SUBSCRIPTION RIGHTS We are distributing non-transferable subscription rights to shareholders who owned shares of our common stock on [November ], 2000, at no cost to the shareholders. We will give you [ ] subscription rights for each share of common stock that you owned on [November ], 2000. You will not receive fractional subscription rights during the rights offering, but instead we will round your number of 12 16 subscription rights down to the nearest whole number. Each subscription right will entitle you to purchase one share of common stock for $[ ]. If you wish to exercise your subscription rights, you must do so before 5:00 p.m., Eastern Standard Time, on [ ], 2000. After that date, the subscription rights will expire and will no longer be exercisable. BASIC SUBSCRIPTION PRIVILEGE Each subscription right will entitle you to receive one share of common stock upon payment of $[ ] per share. You will receive certificates representing the shares that you purchase pursuant to your basic subscription privilege as soon as practicable after [ ], 2000, whether you exercise your subscription rights immediately prior to that date or earlier. OVER-SUBSCRIPTION PRIVILEGE Subject to the allocation described below, each subscription right also grants each shareholder an over-subscription privilege to purchase additional shares of common stock that are not purchased by other shareholders pursuant to their basic subscription privileges. You are entitled to exercise your over- subscription privilege only if you exercise your basic subscription rights in full. Inberdon, our majority shareholder, has expressed its willingness not to subscribe for additional shares pursuant to this over-subscription privilege, thus stepping back to allow other fully subscribing shareholders to purchase additional shares if they wish. If you wish to exercise your over-subscription privilege, you should indicate the number of additional shares that you would like to purchase in the space provided on your subscription certificate. When you send in your subscription certificate, you must also send the full purchase price for the number of additional shares that you have requested to purchase (in addition to the payment due for shares purchased through your basic subscription privilege). If the number of shares remaining after the exercise of all basic subscription privileges is not sufficient to satisfy all requests for shares pursuant to over-subscription privileges, you will be allocated additional shares pro rata (subject to elimination of fractional shares), based on the number of shares you purchased through the basic subscription privilege in proportion to the total number of shares that you and other over-subscribing shareholders purchased through the basic subscription privilege. However, if your pro rata allocation exceeds the number of shares you requested on your subscription certificate, then you will receive only the number of shares that you requested, and the remaining shares from your pro rata allocation will be divided among other shareholders exercising their over-subscription privileges. Subject to state securities laws and regulations, we have the discretion to issue less than the total number of shares that may be available for over-subscription requests in order to comply with state securities laws. As soon as practicable after [ ], 2000, Harris Trust Company of New York, acting as our Subscription Agent, will determine the number of shares of common stock that you may purchase pursuant to the over-subscription privilege. You will receive certificates representing these shares as soon as practicable after [ ]. Subject to state securities laws and regulations, we have the discretion to delay allocation and distribution of any and all shares to shareholders affected by such regulations, who elect to participate in the rights offering, including shares that we issue with respect to your basic or over-subscription privilege in order to comply with state securities laws. If you request and pay for more shares than are allocated to you, we will refund that overpayment, without interest. In connection with the exercise of the over-subscription privilege, banks, brokers and other nominee holders of subscription rights who act on behalf of beneficial owners will be required to certify to the Subscription Agent and United States Lime & Minerals as to the aggregate number of subscription rights that have been exercised, and the number of shares of common stock that are being requested through the over-subscription privilege, by each beneficial owner on whose behalf such nominee holder is acting. 13 17 PURCHASE COMMITMENTS As of [November ], 2000, Inberdon owned approximately [51]% of the outstanding shares of our common stock and, therefore, will receive rights to subscribe for approximately [ ] shares of our common stock in the rights offering. Inberdon has expressed its willingness to fully exercise its basic subscription rights and, if the rights offering is undersubscribed, to purchase the remainder of shares that are not fully subscribed for by other shareholders, in the rights offering. Accordingly, we expect to receive $10,000,000 as a result of the rights offering. NO RECOMMENDATIONS We are not making any recommendation as to whether or not you should exercise your subscription rights. You should make your decision based on your own assessment of your best interests. EXPIRATION DATE The rights will expire at 5:00 p.m., Eastern Standard Time, on [ ], 2000, unless we decide to extend the rights offering. If this commencement of the rights offering is delayed, the expiration date will be similarly extended. If you do not exercise your basic subscription privilege and over-subscription privilege prior to that time, YOUR SUBSCRIPTION RIGHTS WILL BE NULL AND VOID. We will not be required to issue shares of common stock to you if the Subscription Agent receives your subscription certificate or your payment after that time, regardless of when you sent the subscription certificate and payment, unless you send the documents in compliance with the guaranteed delivery procedures described below. CANCELLATION RIGHT Our Board of Directors, excluding the director affiliated with Inberdon, may cancel the rights offering in its sole discretion at any time prior to or on [ ], 2000 for any reason (including, without limitation, a change in the market price of the common stock). If we cancel the rights offering, any funds you paid will be promptly refunded, without interest. DETERMINATION OF SUBSCRIPTION PRICE Our Board of Directors, excluding the director affiliated with Inberdon, set all of the terms and conditions of the rights offering, including the subscription price. Our Board of Directors, excluding the director affiliated with Inberdon, decided to set the per share subscription price at $[ ] after considering a variety of factors including the current and historical market prices of the common stock, our book value per share, our business prospects, general conditions in the securities market, our need for capital, alternatives available to us for raising capital, the amount of proceeds desired, pricing of similar transactions, the liquidity of our common stock, the level of risk to our shareholders, and the need to offer shares at a price that would be acceptable to Inberdon and attractive to our other shareholders relative to the current trading price of our common stock. The $[ ] per share subscription price should not be considered an indication of the actual value of United States Lime & Minerals or our common stock. We cannot assure you that the market price of the common stock will not decline during the rights offering. We also cannot assure you that you will be able to sell shares of common stock purchased during the rights offering at a price equal to or greater than $[ ] per share. See "Determination of Offering Price." NON-TRANSFERABILITY OF SUBSCRIPTION RIGHTS Only you may exercise the basic subscription privilege and the over-subscription privilege. You may not sell, give away or otherwise transfer the basic subscription privilege or the over-subscription privilege. 14 18 EXERCISE OF SUBSCRIPTION RIGHTS You may exercise your subscription rights by delivering to the Subscription Agent on or prior to [ ]: - A properly completed and duly executed subscription certificate; - Any required signature guarantees; and - Payment in full of $[ ] per share of common stock to be purchased through the basic subscription privilege and the over-subscription privilege. You should deliver your subscription certificate and payment to the Subscription Agent at the address shown under the heading "Subscription Agent." We will not pay you interest on funds delivered to the Subscription Agent pursuant to the exercise of rights. METHOD OF PAYMENT Payment for the shares must be made by check or bank draft (cashier's check) drawn upon a U.S. bank or a postal, telegraphic or express money order payable to "Harris Trust Company of New York, AS SUBSCRIPTION AGENT" or by wire transfer of immediately available funds to the account maintained by the Subscription Agent at 88 Pine Street, 19th Floor, New York, New York 10005. Any wire transfer of funds should clearly indicate the identity of the subscriber who is paying the subscription price by the wire transfer. If you are purchasing an aggregate number of shares of common stock totaling $500,000 or more, we may agree to an alternative payment method, which may include, for example, cancellation of debt. If you use an alternative payment method, the Subscription Agent must receive the full amount of your payment in currently available funds within one over-the-counter ("OTC") trading day prior to [ ], 2000. Payment will be deemed to have been received by the Subscription Agent only upon: (A) clearance of any uncertified check; (B) receipt by the Subscription Agent of any certified check or bank draft drawn upon U.S. bank, any postal, telegraphic or express money order or any funds transferred by wire transfers; (C) receipt of good funds in the Subscription Agent's account designated above; or (D) receipt of funds by the Subscription Agent through an alternative payment method. Please note that funds paid by uncertified personal check may take at least five business days to clear. Accordingly, if you wish to pay by means of an uncertified personal check, we urge you to make payment sufficiently in advance of [ ], 2000 to ensure that the payment is received and clears before that date. We also urge you to consider payment by means of a certified or cashier's check or money order. GUARANTEED DELIVERY PROCEDURES If you want to exercise your subscription rights, but time will not permit your subscription certificate to reach the Subscription Agent on or prior to [ ], 2000 you may exercise your subscription rights if you satisfy the following guaranteed delivery procedures: (1) You send, and the Subscription Agent receives, payment in full for each share of common stock being subscribed for through the basic subscription privilege and the over-subscription privilege, on or prior to [ ], 2000; (2) You send, and the Subscription Agent receives, on or prior to [ ], 2000, a notice of guaranteed delivery, substantially in the form provided with the attached instructions, from a member firm of a registered national securities exchange or a member of the National Association of Securities Dealers, Inc., or a commercial bank or trust company having an office or correspondent in the United States. The notice of guaranteed delivery must state your name, the number of 15 19 subscription rights that you hold, the number of shares of common stock that you wish to purchase pursuant to the basic subscription privilege and the number of shares, if any, you wish to purchase pursuant to the over-subscription privilege. The notice of guaranteed delivery must guarantee the delivery of your subscription certificate to the Subscription Agent within three OTC trading days following the date of the notice of guaranteed delivery; and (3) You send, and the Subscription Agent receives, your properly completed and duly executed subscription certificate, including any required signature guarantees, within three OTC trading days following the date of your notice of guaranteed delivery. The notice of guaranteed delivery may be delivered to the Subscription Agent in the same manner as your subscription certificate at the addresses set forth under the heading "Subscription Agent," or may be transmitted to the Subscription Agent by facsimile transmission, to facsimile number (212) 701-7864. You can obtain additional copies of the form of notice of guaranteed delivery by requesting them from the Subscription Agent at the address set forth under the heading "Subscription Agent." SIGNATURE GUARANTEES Signatures on the subscription certificate must be guaranteed by an Eligible Guarantor Institution, as defined in Rule 17Ad-15 of the Securities Exchange Act of 1934, as amended, subject to the standards and procedures adopted by the Subscription Agent. Eligible Guarantor Institutions include banks, brokers, dealers, credit unions, national securities exchanges and savings associations. Signatures on the subscription certificate do not need to be guaranteed if either the subscription certificate provides that the shares of common stock to be purchased are to be delivered directly to the record owner of such subscription rights, or the subscription certificate is submitted for the account of a member firm of a registered national securities exchange or a member of the National Association of Securities Dealers, Inc., or a commercial bank or trust company having an office or correspondent in the United States. SHARES HELD FOR OTHERS If you are a broker, a trustee or a depository for securities, or you otherwise hold shares of common stock for the account of a beneficial owner of common stock, you should notify the beneficial owner of such shares as soon as possible to obtain instructions with respect to their subscription rights. If you are a beneficial owner of common stock held by a holder of record, such as a broker, trustee or a depository for securities, you should contact the holder and ask him or her to effect transactions in accordance with your instructions. Notwithstanding the above, if you are a current or former employee of ours who beneficially owns shares of our common stock which are held in our 401(k) plan (formerly the ESOP), we will treat those shares as part of your record ownership for purposes of calculating your subscription rights. AMBIGUITIES IN EXERCISE OF SUBSCRIPTION RIGHTS If you do not specify the number of subscription rights being exercised on your subscription certificate, or if your payment is not sufficient to pay the total purchase price for all of the shares that you indicated you wished to purchase, you will be deemed to have exercised the maximum number of subscription rights that could be exercised for the amount of the payment that the Subscription Agent receives from you. If your payment exceeds the total purchase price for all of the subscription rights shown on your subscription certificate, your payment will be applied, until depleted, to subscribe for shares of common stock in the following order: (1) to subscribe for the number of shares, if any, that you indicated on the subscription certificate that you wished to purchase through your basic subscription privilege; (2) to subscribe for shares of common stock until your basic subscription privilege has been fully exercised; 16 20 (3) to subscribe for additional shares of common stock pursuant to the over-subscription privilege (subject to any applicable proration). Any excess payment remaining after the foregoing allocation will be returned to you as soon as practicable by mail, without interest or deduction. REGULATORY LIMITATION We will not be required to issue you shares of common stock pursuant to the rights offering if, in our opinion, you would be required to obtain prior clearance or approval from any state or federal regulatory authorities to own or control such shares if, at the time the subscription rights expire, you have not obtained such clearance or approval. OUR DECISION BINDING All questions concerning the timeliness, validity, form and eligibility of any exercise of subscription rights will be determined by us, and our determinations will be final and binding. In our sole discretion, we may waive any defect or irregularity, or permit a defect or irregularity to be corrected within such time as we may determine, or reject the purported exercise of any subscription right by reason of any defect or irregularity in such exercise. Subscriptions will not be deemed to have been received or accepted until all irregularities have been waived or cured within such time as we determine in our sole discretion. Neither United States Lime & Minerals nor the Subscription Agent will be under any duty to notify you of any defect or irregularity in connection with the submission of a subscription certificate or incur any liability for failure to give such notification. NO REVOCATION After you have exercised your basic subscription privilege or over-subscription privilege, YOU MAY NOT REVOKE THAT EXERCISE. You should not exercise your subscription rights unless you are certain that you wish to purchase additional shares of common stock at the subscription price. SHARES OF COMMON STOCK OUTSTANDING AFTER THE RIGHTS OFFERING Assuming we issue all of the shares of common stock offered in the rights offering, approximately [ ] shares of common stock will be issued and outstanding. This would represent a [ ]% increase in the number of outstanding shares of common stock. IF YOU DO NOT EXERCISE YOUR BASIC SUBSCRIPTION PRIVILEGE, THE PERCENTAGE OF COMMON STOCK THAT YOU HOLD WILL DECREASE. 17 21 CAPITALIZATION TABLE The following table sets forth our cash and cash equivalents, current installments of long-term debt and revolving credit facility, long-term debt, excluding current installments and revolving credit facility, and stockholders' equity as of September 30, 2000, and as adjusted to reflect the $10,000,000 proceeds from the Rights Offering and the New Loan, as if the Rights Offering had closed as of September 30, 2000 and we had drawn down the additional $7,000,000 under the New Loan as of that date.

In addition, you do not have the benefit of a sinking fund for your shares of common stock. Your common stock is not redeemable by United States Lime & Minerals. USE OF PROCEEDS We expect to receive gross proceeds from the rights offering of $10,000,000. We will apply the net proceeds from the offering, estimated to be approximately $[ ], to: (i) provide $5,000,000 of new equity capital which, together with the New Loan of $7,000,000, will be used for the construction of Arkansas Phase II; and (ii) provide us, along with the Revolver, with ongoing working capital. Any excess will be used for general corporate purposes. Even if we receive proceeds of $10,000,000, if the cost of Arkansas Phase II increases, or if we fail to attain sufficient levels of operating income, we may require additional capital. We cannot assure you that such capital will be available on satisfactory terms. DETERMINATION OF OFFERING PRICE Our Board of Directors, excluding the director affiliated with Inberdon, set all of the terms and conditions of the rights offering, including the subscription price. Our Board of Directors, excluding the director affiliated with Inberdon, decided to charge a $[ ] per share subscription price after considering a variety of factors, including the current and historical market prices of the common stock, our book value per share, our business prospects, general conditions in the securities market, our need for capital, alternatives available to us for raising capital, the amount of proceeds desired, pricing of similar transactions, the liquidity of our common stock, the level of risk to our shareholders, and the need to offer shares at a price that would be acceptable to Inberdon and attractive to our other shareholders relative to the current trading price of our common stock. The $[ ] per share price should not be considered an indication of the actual value of United States Lime & Minerals or our common stock. We cannot assure you that the market price of the common stock will not decline during the rights offering. We also cannot assure you that you will be able to sell shares of common stock purchased during the rights offering at a price equal to or greater than $[ ] per share. 19 23 PLAN OF DISTRIBUTION On or about [November ], 2000, we will distribute the subscription rights and copies of this prospectus to individuals who owned shares of common stock on [November ], 2000. If you wish to exercise your subscription rights and purchase shares of common stock, you should complete the subscription certificate and return it, with payment for the shares, to the Subscription Agent, Harris Trust Company of New York, at the address on page 18. See "The Rights Offering -- Exercise of Subscription Rights." If you have any questions, you should contact our Vice President of Finance, Company Secretary and Corporate Controller, Larry T. Ohms, at the telephone number and address on page 19. FEDERAL INCOME TAX CONSIDERATIONS The following summarizes the material federal income tax considerations of the rights offering to you and United States Lime & Minerals. This summary is based on current law, which is subject to change at any time, possibly with retroactive effect. This summary is not a complete discussion of all federal income tax consequences of the rights offering, and, in particular, may not address federal income tax consequences applicable to shareholders subject to special treatment under federal income tax law. In addition, this summary does not address the tax consequences of the rights offering under applicable state, local or foreign tax laws. This discussion assumes that your shares of common stock and the subscription rights and shares issued to you during the rights offering constitute capital assets. Receipt and exercise of the subscription rights distributed pursuant to the rights offering is intended to be nontaxable to shareholders, and the following summary assumes you will qualify for such nontaxable treatment. If, however, the rights offering does not qualify as nontaxable, you would be treated as receiving a taxable distribution equal to the fair market value of the subscription rights on their distribution date. The distribution would be taxed as a dividend to the extent made out of United States Lime & Minerals' current or accumulated earnings and profits; any excess would be treated first as a return of your basis (investment) in your United States Lime & Minerals stock and then as a capital gain. Expiration of the subscription rights would result in a capital loss. This discussion is included for your general information only. You should consult your tax advisor to determine the tax consequences to you of the rights offering in light of your particular circumstances, including any state, local and foreign tax consequences. TAXATION OF SHAREHOLDERS Receipt of a Subscription Right. You will not recognize any gain or other income upon receipt of a subscription right. Tax Basis and Holding Period of Subscription Rights. Your tax basis in each subscription right will effectively depend on whether you exercise the subscription right or allow the subscription right to expire. If you exercise a subscription right, your tax basis in the subscription right will be determined by allocating the tax basis of your common stock on which the subscription right is distributed between the common stock and the subscription right, in proportion to their relative fair market values on the date of distribution of the subscription right. However, if the fair market value of your subscription rights is less than 15 percent of the fair market value of your existing shares of common stock, then the tax basis of each subscription right will be deemed to be zero, unless you elect, by attaching an election statement to your federal income tax return for 2000, to allocate tax basis to your subscription rights. If you allow a subscription right to expire, it will be treated as having no tax basis. Your holding period for a subscription right will include your holding period for the shares of common stock upon which the subscription right is issued. Expiration of Subscription Rights. You will not recognize any loss upon the expiration of a subscription right. 20 24 Exercise of Subscription Rights. You generally will not recognize a gain or loss on the exercise of a subscription right. The tax basis of any share of common stock that you purchase through the rights offering will be equal to the sum of your tax basis (if any) in the subscription right exercised and the price paid for the share. The holding period of the shares of common stock purchased through the rights offering will begin on the date that you exercise your subscription rights. TAXATION OF UNITED STATES LIME & MINERALS We will not recognize any gain, other income or loss upon the issuance of the subscription rights, the lapse of the subscription rights, or the receipt of payment for shares of common stock upon exercise of the subscription rights. STATE AND FOREIGN SECURITIES LAWS The rights offering is not being made in any state or other jurisdiction in which it is unlawful to do so, nor are we selling or accepting any offers to purchase any shares of common stock to you if you are a resident of any such state or other jurisdiction. We may delay the commencement of the rights offering in certain states or other jurisdictions in order to comply with the securities law requirements of such states or other jurisdictions. It is not anticipated that there will be any changes in the terms of the rights offering. In our sole discretion, we may decline to make modifications to the terms of the rights offering requested by certain states or other jurisdictions, in which case shareholders who live in those states or jurisdictions will not be eligible to participate in the rights offering.

INDEMNIFICATION OF DIRECTORS AND OFFICERS Section 2.02-1 of the Texas Business Corporation Act, as amended, authorizes us to indemnify our officers and directors and certain other persons in certain instances. In addition, Section 2.02-1 and our Bylaws require that we indemnify any director or officer against reasonable expenses he incurs in connection with a wholly successful defense of a proceeding in which he is a named defendant or respondent because he is or was a director or officer. This indemnification will only occur with the determination that the person (i) conducted himself in good faith, (ii) reasonably believed, in the case of conduct in his official capacity as our director or officer, that his conduct was in our best interests and, in all other cases, that his conduct was at least not opposed to our best interests, and (iii), in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. However, if the director or officer is found liable to us or is found liable on the basis that personal benefit was improperly received, the indemnification shall be limited to reasonable expenses actually incurred in connection with the proceeding. Indemnification shall not be made in respect of any proceeding in which the person shall have been found liable for willful or intentional misconduct in the performance of his duty to us. The Bylaws generally require determinations that the person to be indemnified has satisfied the prescribed conduct and belief standards, as determined by directors who are not themselves then named defendants or respondents in the proceeding, by a special legal counsel selected by the Board of Directors or a committee thereof, or by shareholders in a vote that excludes the shares held by directors and officers who are named defendants or respondents in the proceeding. The Bylaws further require us to pay or reimburse expenses incurred by a director or officer in connection with his appearance as a witness or other participation in a proceeding at a time when he is not a named defendant or respondent in the proceeding. We must also advance reasonable expenses to a director or officer upon receipt of a good faith affirmation by him that he has met the standard of conduct necessary for indemnification and a written undertaking to repay such advances if it is ultimately determined that he has not met those requirements. The Bylaws permit us to indemnify and advance expenses to an officer, employee, or agent to such further extent as may be consistent with law, including persons serving another entity in various capacities II-1 27 at our request. The Bylaws also authorize us to purchase and maintain insurance or make other arrangements on behalf of directors, officers, employees, and agents against or in respect of liabilities. Any indemnification of or advance of expenses to a director under the Bylaws or any statute must be reported in writing to shareholders not later than the notice of the next shareholders' meeting or the next submission to shareholders of a consent to action without a meeting and, in any event, within the 12-month period immediately following the indemnification or advance.

UNDERTAKINGS The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the "Securities Act"); (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) To include any additional or changed material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, paragraphs (i) and (ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934, as amended, that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities II-2 28 offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (4) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-3 29 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant, United States Lime & Minerals, Inc., certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Dallas, State of Texas, on this 30th day of October, 2000.
