                                   (Unaudited)

1.   Basis of Presentation


         Presentation. The condensed consolidated financial statements included
     herein have been prepared by 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 and cash flows for the periods presented have been
     made. Certain information and footnote disclosures normally included in
     financial statements prepared in accordance with generally accepted
     accounting principles have been condensed or omitted. It is suggested that
     these condensed consolidated financial statements 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,
     2002. The results of operations for the three-month and nine-month periods
     ended September 30, 2003 are not necessarily indicative of operating
     results for the full year.

         Stock-based Compensation. The Company accounts for stock-based
     compensation using the intrinsic value method prescribed by Accounting
     Principles Board Opinion No. 25, "Accounting for Stock Issued to
     Employees." Stock-based compensation expense associated with option grants
     was not recognized in the net income for the nine-month periods ended
     September 30, 2003 and 2002, as all options granted have had exercise
     prices equal to the market value of the underlying common stock on the
     dates of grant. The following table illustrates the effect on net income
     and income per common share if the Company had applied the fair-value-based
     recognition provisions of Statement of Financial Accounting Standards No.
     123, "Accounting for Stock-Based Compensation," to stock-based employee
     compensation:

2.   Embezzlement-Related Costs and Recoveries

         On January 31, 2002, the Company announced that it had discovered that
     an employee who had recently left the Company may have improperly diverted
     Company funds without authorization. Trading in the Company's common stock
     on the Nasdaq National Market(R) ("Nasdaq") was halted, and the Audit
     Committee of the Company's Board of Directors retained outside counsel to
     conduct a special investigation into the matter. The Audit Committee also
     retained an independent accounting firm to review the Company's internal
     controls and to make recommendations for improvement that the Company has
     implemented. The Company also contacted the Securities and Exchange
     Commission (the "SEC"), as well as criminal authorities, and cooperated
     with the SEC, Nasdaq, and criminal authorities with respect to their
     investigations into this matter.

         The Company's former Vice President -- Finance, Controller, Treasurer,
     and Secretary, Larry Ohms (the "Former VP Finance"), over a period of four
     years beginning in 1998, embezzled approximately $2,179,000 from the
     Company. The Former VP Finance voluntarily resigned from the Company on
     January 22, 2002, approximately one week before the Company discovered the
     defalcations. The Former VP Finance has stated that no one else at the
     Company was involved in perpetrating the embezzlements. From the results of
     the special investigation and Mr. Ohms' testimony, the Company believes
     this statement to be accurate. In 2002, Mr. Ohms pleaded guilty to one
     count of wire fraud and one count of making a false statement to the SEC,
     and on March 24, 2003 he was sentenced to a term in federal prison and
     ordered to pay $2,179,000 in restitution to the Company.

         On March 14, 2002, the Company received $500,000 in insurance proceeds
     from the Company's insurance policies covering employee theft. The $500,000
     was recorded on the Consolidated Balance Sheet at December 31, 2001 in
     prepaid expenses and other assets, and recognized in the Consolidated
     Statement of Operations in other income in the fourth quarter 2001. In
     addition, the Company retained counsel for assistance in its efforts to
     recover the embezzled funds from the Former VP Finance, and to pursue
     possible civil actions on behalf of the Company against third parties. The
     Company filed suit against the Former VP Finance and has obtained a
     judgment against him, including compensatory and punitive damages. The
     Former VP Finance has claimed not to have any funds.

         Recoveries are being recognized in the quarters in which the recoveries
     are realized, and the costs of the Company's special investigation, the
     Company's cooperation with the SEC, Nasdaq, and criminal authorities in
     their investigations and the Company's ongoing recovery efforts are being
     expensed as incurred. During the first nine months 2003, the Company
     recorded recoveries of $783,000 ($0.14 per share), net of income taxes
     ($921,000 gross), and embezzlement-related costs of $172,000 ($0.03 per
     share), net of income tax benefits ($202,000 gross), compared to
     embezzlement-related costs of $546,000 ($0.09 per share), net of income tax
     benefits ($642,000 gross), in the first nine months 2002.

4.   Banking Facilities and Other Debt

         On April 22, 1999, the Company entered into a credit agreement with a
     consortium of commercial banks for a $50,000,000 Senior Secured Term Loan
     (the "Loan"). The Loan is repayable over a period of approximately eight
     years, maturing on March 30, 2007, and requires monthly principal payments
     of $278,000, which began April 30, 2000, with a final principal payment of
     $26,944,000 on March 30, 2007, which equates to a 15-year amortization. The
     Company paid a fee equivalent to 2.50% of the Loan value to the placement
     agent.

         The interest rate on the first $30,000,000 of the Loan is 8.875%. The
     subsequent installments bear interest from the date they were funded at
     3.52% above the secondary market yield of the United States Treasury
     obligation maturing May 15, 2005. The blended rate for the additional
     $20,000,000 is 9.84%.

         The Loan is secured by a first lien on substantially all of the
     Company's assets, with the exception of accounts receivable and inventories
     which secure the Company's $5,000,000 revolving credit facility. The Loan
     agreement contains covenants that restrict the incurrence of debt,
     guaranties and liens, and places certain restrictions on the payment of
     dividends and the sale of significant assets. The Company is also required
     to meet minimum debt service coverage ratios on an ongoing basis and
     maintain a minimum level of tangible net worth.

         On January 31, 2003, the maturity of the Company's $5,000,000 revolving
     credit facility was extended to July 31, 2003. From January 1, 2003 through
     March 2, 2003, the revolving credit facility bore interest at LIBOR plus a
     margin of 1.40% to 3.55%, in accordance with a defined rate spread based
     upon the Company's then-current ratio of total funded debt to earnings
     before interest, taxes, depreciation and amortization (EBITDA).

         On March 3, 2003, the Company entered into a Loan and Security
     Agreement with another bank for a $5,000,000 revolving credit facility to
     replace the prior facility. In addition, the Company obtained a new
     $2,000,000 equipment line of credit (available for financing or leasing
     large mobile equipment used in its operations) from the same bank. The new
     revolving credit facility is secured by the Company's accounts receivable
     and inventories, provides for an interest rate of LIBOR plus 2.75%, and
     matures on March 1, 2004. As of September 30, 2003, the Company had no
     outstanding balance on the revolving credit facility. The outstanding
     balance of the revolving credit facility was repaid in full on August 5,
     2003 with proceeds from the private placement discussed below, and the Loan
     and Security Agreement was amended to allow the revolving credit facility
     to be increased to $6,000,000 at the Company's option. The average interest
     rate for the revolving credit facilities for the outstanding balances in
     2003 was 4.04%. As



                                  Page 7 of 14


     of October 31, 2003, the Company had entered into approximately $1,100,000
     of operating leases for mobile equipment under the $2,000,000 equipment
     line.

         In April 2003, the Company engaged Frost Securities, Inc. ("Frost") to
     advise it on possible financing alternatives for the Phase II expansion of
     the Company's Arkansas facilities. Frost contacted potential sources of
     financing and obtained several term sheet proposals for a subordinated debt
     placement from outside investors. In conjunction with the review of the
     proposals and further negotiations, Frost and the Company renewed
     discussions with the Company's two largest shareholders and a third party
     to determine whether they would be interested in the investment on terms
     more favorable to the Company than those currently available from other
     potential outside investors.

         On August 5, 2003, the Company sold $14,000,000 of unsecured
     Subordinated Notes (the "Sub Notes") in a private placement under Section
     4(2) of the Securities Act of 1933 to three accredited investors, one of
     which is an affiliate of Inberdon Enterprises Ltd., the Company's majority
     shareholder, and another of which is an affiliate of Robert S. Beall, who
     owns approximately 11% of the Company's outstanding shares. The Company
     believes that the terms of the private placement are more favorable to the
     Company than the proposals previously received. Frost provided an opinion
     to the Company's Board of Directors that, from a financial point of view,
     the private placement was fair to the unaffiliated holders of the Company's
     common stock in relation to other potential subordinated debt transactions
     currently available to the Company. The Company paid Frost an aggregate of
     $381,000 for its advice, placement services and opinion.

         The net proceeds of approximately $13,425,000 from the private
     placement will be used to fund the Phase II expansion of the Company's
     Arkansas facilities. Terms of the Sub Notes include: a maturity date of
     August 5, 2008, subject to acceleration upon a change in control; no
     mandatory principal payments prior to maturity; an interest rate of 14%
     (12% paid in cash and 2% paid in cash or in kind at the Company's option);
     and, except as discussed below, no optional prepayment prior to August 5,
     2005 and a 4% prepayment penalty if repaid before maturity. The terms of
     the Sub Notes are identical to one another, except that the Sub Note for
     the affiliate of Inberdon Enterprises Ltd. does not prohibit prepayment
     prior to August 5, 2005 and does not require a prepayment penalty if repaid
     before maturity, resulting in a weighted average prepayment penalty of
     approximately 2.4% if the Sub Notes are repaid before maturity. The Sub
     Notes include covenants similar to the covenants for the Loan.

         The private placement also included six-year detachable warrants,
     providing the Sub Note investors the right to purchase an aggregate of
     162,000 shares of the Company's common stock, at 110% of the average
     closing price of one share of common stock for the trailing 30 trading days
     prior to closing, or $3.84. After August 5, 2008, or upon an earlier change
     in control, the investors may require the Company to repurchase any or all
     shares acquired through exercise of the warrants (the "Warrant Shares").
     The repurchase price for each Warrant Share will equal the average closing
     price of one share of the Company's common stock for the 30 trading days
     preceding the date the Warrant Shares are put back to the Company. Changes
     in the repurchase price for each Warrant Share are accreted or decreted
     over the five year period from the date of issuance to August 5, 2008. The
     investors are also entitled to certain registration rights for the resale
     of their Warrant Shares.

         As a result of certain negotiations with the Company's existing bank
     lenders, the Loan and the revolving credit facility were amended to approve
     the terms of the Sub Notes. As part of these amendments, the Company is
     prohibited from paying any dividends in cash through June 30, 2005 without
     the prior written consent of the bank lenders.

LIQUIDITY AND CAPITAL RESOURCES

     Net cash provided by operations was $6,768,000 for the nine months ended
September 30, 2003, compared to $5,808,000 for the nine months ended September
30, 2002. The $960,000 increase resulted from the $2,552,000 increase in net
income in the 2003 period compared to the same period in 2002, partially offset
by changes in working capital. The most significant working capital change was a
$2,766,000 increase in trade receivables, net in the first nine months 2003,
compared to a $1,233,000 increase in the comparable 2002 period due to increased
sales.

     The Company invested $5,074,000 in capital expenditures in the first nine
months 2003, $2,064,000 of which related to the Phase II expansion of the
Company's Arkansas facilities, compared to $2,913,000 in the same period last
year.

     Net cash provided by financing activities was $9,435,000 in the first nine
months 2003, primarily from net proceeds of approximately $13,425,000 from the
private placement discussed below and $2,201,000 of draws on the Company's
revolving credit facility, partially offset by $3,401,000



                                  Page 9 of 14



repayment in full of the revolving credit facility, $2,500,000 repayment of debt
and $290,000 payment of cash dividends. Financing activities used $3,039,000 net
cash in the first nine months 2002, primarily for $4,350,000 repayment of debt
and $439,000 payment of cash dividends, partially offset by $1,750,000 of draws
on the Company's revolving credit facility.

     On March 3, 2003, the Company entered into a Loan and Security Agreement
with another bank for a new $5,000,000 revolving credit facility to replace the
prior facility. In addition, the Company obtained a new $2,000,000 equipment
line of credit (available for financing or leasing large mobile equipment used
in its operations) from the same bank. The new revolving credit facility is
secured by the Company's accounts receivable and inventories, provides for an
interest rate of LIBOR plus 2.75%, and matures on March 1, 2004. As of September
30, 2003, the Company had no outstanding balance on the revolving credit
facility. The outstanding balance of the revolving credit facility was repaid in
full on August 5, 2003 with proceeds from the private placement discussed below,
and the Loan and Security Agreement was amended to allow the revolving credit
facility to be increased to $6,000,000 at the Company's option. The average
interest rate for the revolving credit facilities for the outstanding balances
in 2003 was 4.04%. As of October 31, 2003, the Company had entered into
approximately $1,100,000 of operating leases for mobile equipment under the new
$2,000,000 equipment line. The Company believes that funds generated from
operations, amounts available under the revolving credit facility and funds from
the private placement will be sufficient to meet the Company's liquidity and
ongoing capital needs for the year and to complete the Arkansas Phase II
expansion project.

     In April 2003, the Company engaged Frost Securities, Inc. ("Frost") to
advise it on possible financing alternatives for the Phase II expansion of the
Company's Arkansas facilities. Frost contacted potential sources of financing
and obtained several term sheet proposals for a subordinated debt placement from
outside investors. In conjunction with the review of the proposals and further
negotiations, Frost and the Company renewed discussions with the Company's two
largest shareholders and a third party to determine whether they would be
interested in the investment on terms more favorable to the Company than those
currently available from other potential outside investors. The Company paid
Frost an aggregate of $381,000 for its advice, placement services and opinion.

     On August 5, 2003, the Company sold $14,000,000 of unsecured Subordinated
Notes (the "Sub Notes") in a private placement under Section 4(2) of the
Securities Act of 1933 to three accredited investors, one of which is an
affiliate of Inberdon Enterprises Ltd., the Company's majority shareholder, and
another of which is an affiliate of Robert S. Beall, who owns approximately 11%
of the Company's outstanding shares. The Company believes that the terms of the
private placement are more favorable to the Company than the proposals
previously received. Frost provided an opinion to the Company's Board of
Directors that, from a financial point of view, the private placement was fair
to the unaffiliated holders of the Company's common stock in relation to other
potential subordinated debt transactions currently available to the Company.

     The net proceeds of approximately $13,425,000 from the private placement
will be used to fund the Phase II expansion of the Company's Arkansas
facilities. Terms of the Sub Notes include: a maturity date of August 5, 2008,
subject to acceleration upon a change in control; no mandatory principal
payments prior to maturity; an interest rate of 14% (12% paid in cash and 2%
paid in cash or in kind at the Company's option); and, except as discussed
below, no optional prepayment prior to August 5, 2005 and a 4% prepayment
penalty if repaid before maturity. The terms of the Sub Notes are identical to
one another, except that the Sub Note for the affiliate of Inberdon Enterprises
Ltd. does not prohibit prepayment prior to August 5, 2005 and does not require a
prepayment penalty if repaid before maturity, resulting in a weighted average
prepayment penalty of approximately 2.4% if the Sub



                                 Page 10 of 14



Notes are repaid before maturity. The Sub Notes include covenants similar to the
covenants for the Loan.

     The private placement also included six-year detachable warrants, providing
the Sub Note investors the right to purchase an aggregate of 162,000 shares of
the Company's common stock, at 110% of the average closing price of one share of
common stock for the trailing 30 trading days prior to closing, or $3.84. After
August 5, 2008, or upon an earlier change in control, the investors may require
the Company to repurchase any or all shares acquired through exercise of the
warrants (the "Warrant Shares"). The repurchase price for each Warrant Share
will equal the average closing price of one share of the Company's common stock
for the 30 trading days preceding the date the Warrant Shares are put back to
the Company. Changes in the repurchase price for each Warrant Share are accreted
or decreted over the five year period from the date of issuance to August 5,
2008. The investors are also entitled to certain registration rights for the
resale of their Warrant Shares.

     As a result of certain negotiations with the Company's existing bank
lenders, the Loan and the revolving credit facility were amended to approve the
terms of the Sub Notes. As part of these amendments, the Company is prohibited
from paying any dividends in cash through June 30, 2005 without the prior
written consent of the bank lenders.

     The Arkansas modernization and expansion project began in the fourth
quarter 1999 and was scheduled to be completed in two phases. Phase I involved
the redevelopment of the quarry plant, rebuilding of the railroad to standard
gauge, the purchase of a facility to establish an out-of-state terminal in
Shreveport, Louisiana, the installation of a rotary kiln with preheater and
increased product storage and loading capacity. The kiln in Phase I produced its
first lime in the fourth quarter 2000. The Company completed Phase I in the
second quarter 2001.

     The total cost of Phase I was approximately $33,000,000. The $33,000,000
includes approximately $1,800,000 of costs associated with the pre-building of
certain facilities for Phase II of the Arkansas project and the purchase of, but
not all of the improvements to, the out-of-state terminal in Shreveport,
Louisiana. The estimated additional cost to complete Phase II is approximately
$16,000,000. The Company is financing the completion of the Phase II expansion
principally through the net proceeds of the August 5, 2003 private placement.

     The Phase II expansion will double the Arkansas plant's quicklime
production capacity through the installation of a second kiln system
substantially identical to the kiln system built in Phase I. The plans for Phase
II currently include the completion of the out-of-state terminal in Shreveport,
Louisiana for distribution of the Company's products. Construction of the second
kiln system commenced in the third quarter 2003 and is currently expected to be
completed in the first half 2004.

     The Company is not contractually committed to any planned capital
expenditures until actual orders are placed for equipment. As of September 30,
2003, the Company had open orders of approximately $9,500,000 related to the
Phase II expansion.

     As of September 30, 2003, the Company had $52,333,000 in total debt
outstanding.

RESULTS OF OPERATIONS

     Revenues increased to $12,849,000 in the third quarter 2003 from
$10,496,000 in the third quarter 2002, an increase of $2,353,000, or 22.4%. In
the first nine months 2003, revenues increased $3,500,000 to $33,934,000 from
$30,434,000 in the first nine months 2002, an increase of 11.5%. The increases
in revenues for the third quarter and first nine months 2003 primarily resulted
from increased lime and pulverized limestone ("PLS") sales at the Company's
Texas and Colorado plants.

      The Company's gross profit was $4,387,000 for the third quarter 2003,
compared to $2,739,000 for the second quarter 2002, a 60.2% increase. Gross
profit margin as a percentage of revenues and gross profit increased in the 2003
quarter compared to the 2002 quarter. These increases are primarily



                                 Page 11 of 14



due to the resolution of the operational problems at the Company's Texas plant
that occurred during the third quarter 2002 which resulted in reduced lime
production in the 2002 quarter and increased PLS sales volume during the third
quarter 2003.

     For the first nine months 2003, the Company's gross profit was $9,595,000,
compared to $7,557,000 for the comparable 2002 period, a 27.0% increase. Gross
profit margin as a percentage of revenues and gross profit increased in the
first nine months 2003 compared to the same period last year, primarily due to
the resolution of the operational problems at the Company's Texas plant that
occurred during the second and third quarter 2002 and the increase in PLS sales
volume. These improvements were partially offset in 2003 by increased natural
gas costs and a winter ice storm in Texas that caused the loss of approximately
two days of sales and a natural gas curtailment to the Company's Texas plant
that resulted in reduced production levels during the first quarter 2003. The
total negative price variance for natural gas in the first nine months 2003 was
approximately $800,000 compared to the first nine months 2002, partially offset
by natural gas surcharges on PLS products implemented by the Company in early
March 2003. Since that time, the surcharges have offset most of the increased
natural gas costs.

      Although natural gas prices have declined from their highs during the
first quarter 2003, they continue to exceed 2002 price levels. The Company
expects natural gas prices to remain higher than in the previous year.
Therefore, the Company intends to continue the natural gas surcharges on PLS
products in a continued effort to offset most of the increased costs.

      Selling, general and administrative expenses ("SG&A") increased by
$205,000, or 20.9%, to $1,188,000 in the third quarter 2003, compared to
$983,000 in the third quarter 2002. As a percentage of sales, SG&A declined to
9.2% in the third quarter 2003 from 9.4% in the comparable 2002 quarter. SG&A
increased by $279,000, or 9.4%, to $3,235,000 in the first nine months 2003, as
compared to $2,956,000 in the comparable 2002 period. As a percentage of sales,
SG&A declined to 9.5% in the first nine months 2003 from 9.7% in 2002. The
increases for the third quarter and first nine months 2003 were primarily
attributable to increases in insurance costs, salaries and employee benefits.

      Interest expense in the third quarter 2003 increased $184,000, or 17.2%,
to $1,256,000, compared to $1,072,000 in the third quarter 2002. Interest
expense in the first nine months 2003 increased $28,000, or 0.9%, to $3,315,000,
compared to $3,287,000 in the first nine months 2002. The increase in interest
expense in 2003 primarily resulted from the private placement of the Sub Notes
partially offset by $3,333,000 in repayments on the Loan over the last 12
months. Approximately $59,000 of interest was capitalized in the third quarter
2003 as part of the Arkansas Phase II expansion project.

     Other, net was $3,000 expense in the third quarter 2003, compared to $2,000
income in the third quarter 2002. Other, net was $708,000 income in the first
nine months 2003, as compared to $571,000 expense in the comparable 2002 period.
Other, net in the nine month 2003 period consisted of interest, other income and
$921,000 of embezzlement-related recoveries, partially offset by $202,000 of
embezzlement-related costs. In the first nine months 2002, $642,000 of
embezzlement-related costs was the primary other expense, partially offset by
interest and other income.

     The Company's net income increased $1,057,000 to $1,642,000 ($0.28 per
share) during the third quarter 2003, compared to net income of $585,000 ($0.10
per share) during the third quarter 2002.

     For the first nine months 2003, the Company reported net income of
$3,183,000 ($0.55 per share), an increase of $2,552,000 compared to net income
of $631,000 ($0.11 per share) during the comparable 2002 period.
