3.   Long-Term Debt

     On April 22, 1999, the Company entered into a new 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 8 years,
     maturing on March 30, 2007, and requires monthly principal payments of
     $277,777.78 beginning April 30, 2000, with a final principal payment of
     $26,944,444.26 on March 30, 2007, which equates to a 15-year amortization.

     The Company agreed to pay a fee equivalent to 2-1/2% of the Loan value to
     the placement agent. The fee due on the first $30,000,000 advanced was paid
     on closing, and the fee due on the remaining $20,000,000 was paid in
     September when the first installment of this portion was funded.

     Upon execution of the Loan agreement, the first $30,000,000 was advanced,
     of which approximately $20,000,000 was used to retire all existing bank
     loans, with the balance to be used primarily for the modernization and
     expansion of the Arkansas operations. Under the terms of the Loan
     agreement, the remaining $20,000,000 of the Loan facility could be drawn
     down in four equal quarterly installments beginning June 30, 1999, and
     ending March 30, 2000, and will be used exclusively for the Arkansas
     project. Commencement of the draw down of the quarterly


                                       5
   6


     installments was conditional upon the Company receiving an operating air
     permit for the first phase of the Arkansas project by December 31, 1999. In
     September, the Company received an operating air permit for the
     modernization and expansion of its Arkansas plant, and immediately placed
     construction orders. As a consequence of receiving this permit, during
     September the Company drew down a further $10,000,000, making a total of
     $40,000,000 advanced under the terms of the Loan.

     As of April 22, 1999, the Company also entered into a second amendment of
     its amended and restated loan and security agreement with the lead bank
     which provides for a $4,000,000 revolving credit facility. The current
     agreement contains essentially the same terms as the previous agreement and
     has a maturity date of April 21, 2000.

     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
     have been used to secure the amended $4,000,000 revolving credit facility.
     The interest rate on the first $30,000,000 of the Loan is 8.875%.
     Subsequent installments bear interest from the date they are funded at
     3.52% above the secondary market yield of the United States Treasury
     obligation maturing May 15, 2005. On September 24, 1999, the Company drew
     down $5,000,000 bearing an interest rate of 9.54%. On September 30, 1999,
     the Company drew down a further $5,000,000 bearing an interest rate of
     9.35%. The revolving credit facility bears interest at LIBOR plus 1.40%,
     which rate will increase 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).

     In connection with the repayment of the prior term loan, the Company
     terminated an interest rate protection agreement, which it had entered into
     with its bank to modify the interest characteristics of $9,000,000 of its
     then-outstanding term debt from a variable to a fixed rate (the "Swap
     Agreement"). As a result of the termination of the Swap Agreement, the
     Company was obligated to pay the bank a $102,000 termination payment, which
     was expensed in the second quarter as an adjustment to interest expense.

     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 on-going basis and
     maintain a minimum level of tangible net worth.


     A summary of outstanding debt at the dates indicated is as follows: (In

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


LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $346,000 for the nine months ended
September 30, 1999, as compared to $2,838,000 for the nine months ended
September 30, 1998. The main reason for the decrease in cash from operating
activities was the increased balance of accounts receivable and other assets,
principally consisting of the prepaid financing costs associated with the Loan.

The Company invested $8,166,000 in capital expenditures in the first nine months
of 1999, of which $4,165,000 related to the Arkansas modernization and expansion
project. This compared to capital expenditures of $17,597,000 in the same period
last year, of which $14,763,000 was related to the modernization and expansion
project at the Texas facility. The Texas project was completed in the fourth
quarter of 1998.

In June 1999, the Company purchased the plant and equipment assets of Calco,
Inc. in Salida, Colorado, together with all finished product inventories. Calco,
Inc. produces pulverized limestone products in bagged and bulk form, and the
plant facilities also include a dormant lime kiln. In 1998, the Calco business
had revenues of approximately $1,000,000.

As currently planned, the Arkansas modernization and expansion project will be
completed in two phases: Phase I will cover the redevelopment of the quarry
plant, rebuilding of the railroad, establishment of an out-of-state terminal,
and installation of a rotary kiln with a preheater, along with increased product
storage and loading capacity. Following receipt of the operating air permit in
September, the Company now anticipates producing lime from the new plant during
the third quarter of 2000.

Phase II of the Arkansas project would further expand the plant capacity through
the installation of a second kiln with additional storage capacity. Although the
Company could determine to defer Phase II depending upon such factors as market
demand and the availability of financing, it currently plans to complete Phase
II in the first half of 2001.

The Arkansas improvements should allow the Company to better serve its customers
by improving both quality and service while increasing the production capacity
of quicklime and hydrated lime. With the improvements, the Company expects to be
in a better position to compete for customers who currently cannot use the
Company's lime in their processes due to insufficient production capacity at the
plant or quality constraints. The rotary kiln will have lower operating costs
and a greater capacity than the six shaft kilns currently in use. In addition to
increasing capacity, this kiln will also be able to consistently produce
high-quality lime for use by certain manufacturing customers who currently do
not buy lime from the Arkansas facility. The storage, screening, and load-out
facilities will also substantially reduce the amount of time required for the
loading of bulk quicklime trucks and railcars. The planned modernization and
expansion project will increase both production and shipping capacity, will
lower operating costs, and will allow for a more efficient utilization of the
work force.

Phase I of the Arkansas project is currently projected to cost approximately
$21,500,000. If Phase II proceeds on schedule, it is currently estimated to cost
approximately $11,000,000. The Company intends to finance the Arkansas project
through a combination of the Loan and internally generated funds. There can be
no assurance that sufficient funds will be available to the Company to complete
Phase II of the Arkansas project as currently contemplated.

The Company is not contractually committed to any planned capital expenditures
until actual orders are placed for equipment. As of September 30, 1999, the
Company had liability for open equipment


                                       7

and construction orders in the amount of approximately $7,000,000. All future
billings related to the Arkansas modernization and expansion project will be
recorded as work is performed and billed to the Company.

On April 22, 1999, the Company entered into a new 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 8 years, maturing
on March 30, 2007, and requires monthly principal payments of $277,777.78
beginning April 30, 2000, with a final principal payment of $26,944,444.26 on
March 30, 2007, which equates to a 15-year amortization.

The Company agreed to pay a fee equivalent to 2-1/2% of the Loan value to the
placement agent. The fee due on the first $30,000,000 advanced was paid on
closing, and the fee due on the remaining $20,000,000 was paid in September when
the first installment of this portion was funded.

Upon execution of the Loan agreement, the first $30,000,000 was advanced, of
which approximately $20,000,000 was used to retire all existing bank loans, with
the balance to be used primarily for the modernization and expansion of the
Arkansas operations. Under the terms of the Loan agreement, the remaining
$20,000,000 of the Loan facility could be drawn down in four equal quarterly
installments beginning June 30, 1999, and ending March 30, 2000, and will be
used exclusively for the Arkansas project. Commencement of the draw down of the
quarterly installments was conditional upon the Company receiving an operating
air permit for the first phase of the Arkansas project by December 31, 1999. In
September, the Company received an operating air permit for the modernization
and expansion of its Arkansas plant, and immediately placed construction orders.
As a consequence of receiving this permit, during September the Company drew
down a further $10,000,000, making a total of $40,000,000 advanced under the
terms of the Loan.

As of April 22, 1999, the Company also entered into a second amendment of its
amended and restated loan and security agreement with the lead bank which
provides for a $4,000,000 revolving credit facility. The current agreement
contains essentially the same terms as the previous agreement and has a maturity
date of April 21, 2000.

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 have
been used to secure the amended $4,000,000 revolving credit facility. The
interest rate on the first $30,000,000 of the Loan is 8.875%. Subsequent
installments bear interest from the date they are funded at 3.52% above the
secondary market yield of the United States Treasury obligation maturing May 15,
2005. On September 24, 1999, the Company drew down $5,000,000 bearing an
interest rate of 9.54%. On September 30, 1999, the Company drew down a further
$5,000,000 bearing an interest rate of 9.35%. The revolving credit facility
bears interest at LIBOR plus 1.40%, which rate will increase 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).

In connection with the repayment of the prior term loan, the Company terminated
an interest rate protection agreement, which it had entered into with its bank
to modify the interest characteristics of $9,000,000 of its then-outstanding
term debt from a variable to a fixed rate (the "Swap Agreement"). As a result of
the termination of the Swap Agreement, the Company was obligated to pay the bank
a $102,000 termination payment, which was expensed in the second quarter as an
adjustment to interest expense.

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 on-going
basis and maintain a minimum level of tangible net worth.

As of September 30, 1999, the Company had approximately $40,000,000 in total
debt outstanding.


RESULTS OF OPERATIONS

Revenues were $9,268,000 in the third quarter of 1999, an increase of
$1,845,000, or 24.9%, from the revenues of $7,423,000 in the third quarter of
1998. This resulted from a 20.1% increase in sales volume and a 4.8% increase in
prices. Third quarter trading was strong, particularly in the construction
sector of the Company's business. Improved weather conditions enabled the
Company to recover some of the sales from the second quarter which had been lost
due to inclement weather. Revenues for the nine months ended September 30, 1999
were $23,812,000, an increase of $1,904,000, or 8.7%, from the $21,908,000
reported for the nine months ended September 30, 1998. The increase resulted
from a 5.8% increase in sales volume and a 2.9% increase in prices.

The Company's gross profit was $2,896,000 for the third quarter of 1999,
compared to $1,819,000 for the third quarter of 1998, a 59.2% increase. Gross
profit margin as a percentage of revenues for the third quarter of 1999
increased to 31.2%, from 24.5% in 1998. In the third quarter, gross profit and
gross profit margins improved due to increased sales volumes. Gross profit
increased to $6,805,000 for the first nine months of 1999, from $5,264,000 for
the first nine months of 1998, a 29.3% increase. Gross profit margin for the
nine months ended September 30, 1999 increased to 28.6%, from 24.0% in 1998.

Selling, general and administrative expenses ("SG&A") increased by $56,000, or
6.9%, to $870,000 in the third quarter of 1999, as compared to $814,000 in the
third quarter of 1998, the increase being largely due to the Calco business
acquired in June. SG&A as a percentage of sales decreased to 9.4%, from 11.0% a
year earlier. SG&A increased by $18,000, or 0.7%, to $2,675,000 in the first
nine months of 1999, as compared to $2,657,000 in the first nine months of 1998,
and as a percentage of sales decreased to 11.2%, from 12.1%.

Interest expense in the third quarter of 1999 was $696,000, as compared to
$6,000 in 1998. Interest expense for the first nine months of 1999 was
$1,730,000, as compared to $12,000 in 1998. The 1999 increase was attributable
to a higher debt balance and miscellaneous additional interest expense,
including a $102,000 termination payment in connection with the Company's
termination of the Swap Agreement, which amount was expensed in the second
quarter of 1999. In 1998, substantially all incurred interest costs were
capitalized as part of the Texas modernization and expansion project. Interest
costs of approximately $285,000 and $590,000 were capitalized in the third
quarter and first nine months, respectively, of 1998.

The Company reported net income of $1,113,000 ($0.28 per share) during the third
quarter of 1999, compared to net income of $776,000 ($0.20 per share) during the
third quarter of 1998. For the first nine months of 1999, the Company reported
net income of $2,015,000 ($0.51 per share), compared to net income of $2,142,000
($0.54 per share) in the first nine months of 1998.

EBITDA (earnings before interest, taxes, depreciation and amortization) was
$3,385,000 for the third quarter of 1999, an increase of 205.5% from the third
quarter 1998 of $1,108,000. For the nine months ended September 30, 1999, EBITDA
was $7,898,000, an increase of 54.7% from the $5,104,000 generated in the same
period of 1998.

YEAR 2000 COMPLIANCE

The Company continues to address the potential impact of the Year 2000 ("Y2K")
issue on its operations. The Y2K problem arises because of computer programs
which use two digits rather than four digits to define a year. This may result
in miscalculations or complete system failures in processing data with programs
using date sensitive information.

The Company had inventoried its information technology ("IT") and non-IT
systems, including embedded systems in its production operating equipment, in an
effort to identify potential Y2K problems. By the end of September, the Company
had substantially completed the remediation and testing phases of its Y2K
compliance program.

The Company had been using certain customized accounting software which was not
Y2K compliant. To address this problem, the Company selected and installed a
commercially available accounting software which is Y2K compliant. The cost of
this installation is approximately $200,000.

The Company continues to obtain confirmation from its suppliers and customers
that they are or will be Y2K compliant. The cost of replacing, or of
implementing alternative means of communication with, non-compliant or
non-responsive suppliers will not be possible to determine until the review
process has been completed.

Other than as a result of serious systemic failures in external services, or due
to a significant and extended decline in customer demand as a result of an
inadequate response to the Y2K problem by the Company's customers and their
industries, the Company does not expect the Y2K challenge to have a material
adverse effect on its financial condition, results of operations, or cash flows.


BENEFIT PLANS

Effective July 31, 1999, the Company merged its Employee Stock Option Plan
("ESOP") into its 401(k) Profit Sharing Plan. No contributions had been made to
the ESOP since December 1994.
