           NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS


Note 1

In the opinion of management, the accompanying unaudited consolidated
financial statements contain all adjustments, which are of a normal
recurring nature, necessary to present fairly the financial position of
the Company as of September 30, 1999, and the results of operations for
the three and nine months ended September 30, 1999 and 1998 and the cash
flows for the nine months ended September 30, 1999 and 1998.

The year-end consolidated balance sheet was derived from the Company's
audited financial statements, but does not include all disclosures
required by generally accepted accounting principles. The financial
statements contained herein should be read in conjunction with the
financial statements and related notes in the Company's annual report on
Form 10-K for the year ended December 31, 1998. The Company's operations
are seasonal and, consequently, interim results are not indicative of the
results to be expected for a full year.


Note 2 - Common Stock

In February, May 1999,and August 1999, the Board of Directors declared
$0.05 dividends per common share, which were paid on March 15, 1999, June
15, 1999, and September 15, 1999 to shareholders of record as of March 1,
1999, June 1, 1999, and September 1, 1999. During the nine months ended
September 30, 1999, the Company purchased 1,161,010 shares of its common
stock and 32,007 of its warrants for $39,664,000.


Note 3 - Supplemental Disclosures of Cash Flow Information

Cash equivalents include the Company's marketable securities which are
comprised of short-term, highly liquid investments with original maturities
of three months or less. Interest paid during the nine months ended September
30, 1999 and 1998 was $3,781,000 and $3,734,000, respectively. Income taxes
paid during the nine months ended September 30, 1999 and 1998 were
$15,598,000 and $15,221,000, respectively.


Note 4 - Interest

Interest expense of $945,000, $2,835,000, $945,000, and $12,835,000 has been
accrued for three and nine months ended September 30, 1999 and 1998. Interest
capitalized during the three and nine months ended September 30, 1999 and
1998 was $654,000, $1,275,000, $367,000 and $1,105,000, respectively.


Note 5 - Earnings Per Share

Basic earnings per common share for the three and nine months ended September
30, 1999 and 1998 are calculated by dividing net income by weighted average
common shares outstanding during the period. Diluted earnings per common
share for the three and nine months ended September 30, 1999 and 1998 are
calculated by dividing net income by weighted average common shares
outstanding during the period plus dilutive potential common shares which are
determined as follows:

</TABLE>

Dilutive potential common shares are calculated in accordance with the
treasury stock method which assumes that the proceeds from the exercise of
all warrants and options are used to repurchase common stock at market
value. The number of shares remaining after the proceeds are exhausted
represents the potentially dilutive effect of the securities.


Note 6 - Environmental Regulation

The Company is subject to extensive, stringent and complex federal, state
and local laws, regulations and ordinances pertaining to the quality and
the protection of the environment and human health and safety, requiring
the Company to devote substantial time and resources in an effort to
maintain continued compliance. Many of the laws and regulations apply to
the Company's former activities, properties and facilities as well as its
current operations. There can be no assurances that judicial or
administrative proceedings, seeking penalties or injunctive relief, will
not be brought against the Company for alleged non-compliance with
applicable environmental laws and regulations relating to matters as to
which the Company is currently unaware. For instance, if releases of
hazardous substances are discovered to have occurred at facilities
currently or previously owned or operated by the Company, or at facilities
to which the Company has sent waste materials, the Company may be subject
to liability for the investigation and remediation of such sites. In
addition, changes to such regulations or the enactment of new regulations
in the future could require the Company to undertake capital improvement
projects or to cease or curtail certain operations or could otherwise
substantially increase the capital, operating and other costs associated
with compliance. For example, recent worldwide initiatives for limitations
on carbon dioxide emissions could result in the promulgation of statutes
or regulations that would adversely affect certain aspects of United
States manufacturing, including the cement industry.

The Clean Water Act provides a comprehensive federal regulatory scheme
governing the discharge of pollutants to waters of the United States. This
regulatory scheme requires that permits be secured for discharges of
wastewater, including stormwater runoff associated with industrial
activity, to waters of the United States. The Company has secured or has
applied for all required permits in connection with its wastewater and
stormwater discharges.

The Clean Air Act provides for a uniform federal regulatory scheme
governing the control of air pollutant emissions and permit requirements.
In addition, certain states in which the Company operates have enacted
laws and regulations governing the emission of air pollutants and
requiring permits for sources of air pollutants. The Company is required
to apply for federal operating permits for each of its cement
manufacturing facilities. All of these applications have been made. As
part of the permitting process, the Company may be required to install
equipment to monitor emissions of air pollutants from its facilities. In
addition, the United States Environmental Protection Agency ("EPA") is
required to develop regulations directed at reducing emissions of toxic
air pollutants from a variety of industrial sources, including the
portland cement manufacturing industry. As part of this process, the EPA
has announced maximum available control technology ("MACT") standards for
cement manufacturing facilities (like Lone Star's Greencastle and Cape
Girardeau plants) that burn hazardous waste fuels ("HWF") and other MACT
standards for facilities burning fossil fuels.  These MACT standards will
be implemented over a three-year period. The Company currently anticipates
that it will be able to achieve these MACT standards. The EPA has also
promulgated under the Clean Air Act new standards for small particulate
matter and ozone emissions, and related testing will be carried out over
the next several years. Depending on the result of this testing,
additional regulatory burdens could be imposed on the cement industry by
states not in compliance with the regulations. The EPA has promulgated
(but a court has stayed) new regulations to reduce nitrogen oxide
emissions substantially over the next eight years. These rules, if
implemented, would affect 22 states including three in which the Company
has cement plants: Indiana, Illinois and Missouri. Depending on state
implementation, this emissions reduction could adversely affect the cement
industry in these states.

The Resource Conservation and Recovery Act ("RCRA") establishes a cradle-
to-grave regulatory scheme governing the generation, treatment, storage,
handling, transportation and disposal of solid wastes. Solid wastes which
are classified as hazardous wastes pursuant to RCRA, as well as facilities
that treat, store or dispose of such hazardous wastes, are subject to
stringent regulatory requirements. Generally, wastes produced by the
Company's operations are not classified as hazardous wastes and are
subject to less stringent federal and state regulatory requirements.
However, the EPA has recently proposed regulations imposing controls on
the management, handling and disposal of cement kiln dust ("CKD"), a by-
product of cement manufacturing.  These rules are currently being reviewed
by the Company and are expected to be implemented over a three-year period
following promulgation. The types of controls include fugitive dust
emission controls, restrictions for landfills located in sensitive areas,
groundwater monitoring, standards for liners and caps, metals limits and
corrective action for currently active units.

The Cape Girardeau, Missouri and Greencastle, Indiana plants, which are
the Company's two cement manufacturing facilities using HWF as a cost-
saving energy source, are subject to strict federal, state and local
requirements governing hazardous waste treatment, storage and disposal
facilities, including those contained in the federal Boiler and Industrial
Furnace Regulations promulgated under RCRA (the "BIF Rules"). The Company
has secured the permit required under RCRA and the BIF Rules for the Cape
Girardeau plant, and the Greencastle plant also will go through this
permitting process and has completed a three-year recertification of its
existing interim status, which recertification will be required again
after the Company's expansion of the Greencastle plant in the Year 2000.
The Greencastle permit is a requirement to enable Lone Star to continue
the use of HWF at the plant. The permitting process is lengthy and
complex, involving the submission of extensive technical data, and there
can be no assurances that the plant will be successful in securing its
final RCRA permit. In addition, if received, the permit could contain
terms and conditions with which the Company cannot comply or could require
the Company to install and operate costly control technology equipment.
While Lone Star believes that it is currently in compliance with the
extensive and complex technical requirements of the BIF Rules, there can
be no assurances that the Company will be able to maintain compliance with
the BIF Rules or that changes to such rules or their interpretation by the
relevant agencies or courts might not make it more difficult or cost-
prohibitive to continue to burn HWF.

The federal Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA" or "Superfund"), as well as many comparable state
statutes, creates a joint and several liability scheme for the
investigation and remediation of facilities where releases of hazardous
substances are found to have occurred. Liability may be imposed upon
current owners and operators of the facility, upon owners and operators of
the facility at the time of the release and upon generators and
transporters of hazardous substances released at the facility. While, as
noted above, wastes produced by the Company generally are not classified
as hazardous wastes, many of the raw materials, by-products and wastes
currently and previously produced, used or disposed of by the Company or
its predecessors contain chemical elements or components that have been
designated as hazardous substances or which otherwise may cause
environmental contamination. Hazardous substances are or have been used or
produced by the Company in connection with its cement manufacturing
operations (e.g. grinding compounds, refractory bricks), quarrying
operations (e.g. blasting materials), equipment operation and maintenance
(e.g. lubricants, solvents, grinding aids, cleaning aids, used oils), and
hazardous waste fuel burning operations. Past operations of the Company
have resulted in releases of hazardous substances at sites currently or
formerly owned by the Company and certain of its subsidiaries or where
waste materials generated by the Company have been disposed. CKD and other
materials were placed in depleted quarries and other locations for many
years. The Company has been named by the EPA as a potentially responsible
party for the investigation and remediation of several Superfund sites,
although it does not currently contemplate that future costs relating to
such sites will be material.

The Company's operations are subject to federal and state laws and
regulations designed to protect worker health and safety. Worker
protection at the Company's cement manufacturing facilities is governed by
the federal Mine Safety and Health Act ("MSHA") and at other Company
operations is governed by the federal Occupational Safety and Health Act
("OSHA").


Note 7 - Legal Proceedings

From time to time, the Company is named as a defendant in lawsuits
asserting, among other things, products liability. The Company maintains
such liability insurance coverage for its operations as it deems
reasonable. The Company does not expect the effect of such matters to have
a material effect on the financial condition of the Company.


Note 8 - Subsequent Event

On October 6, 1999, Dyckerhoff Aktiengesellschaft, a corporation formed
under the laws of the Federal Republic of Germany ("Parent"), closed its
previously announced tender offer (the "Offer") for (i) all of the issued
and outstanding shares of common stock, par value $1.00 per share (the
"Shares"), of the Company, together with the associated rights to purchase
common stock (the "Rights") issued pursuant to the Rights Agreement, dated
as of November 10, 1994 between the Company and Chemical Bank, as Rights
Agent, for $50.00 per Share in cash, and (ii) all of the outstanding
common stock purchase warrants (the "Warrants"), each representing the
right to purchase two Shares, issued pursuant to the Warrant Agreement,
dated as of April 13, 1994 between the Company and Chemical Bank, as
Warrant Agent (the "Warrant Agreement"), for $81.25 per Warrant in cash.
The Offer was made pursuant to an Agreement and Plan of Merger, dated as
of September 2, 1999, among Parent, Level Acquisition Corp., a Delaware
corporation ("Purchaser") and the Company (the "Merger Agreement").

On October 8, 1999, pursuant to the Merger Agreement, Purchaser merged
with and into the Company with the Company surviving as an indirect wholly
owned subsidiary of Parent (the "Merger").  The approval of the holders of
the Shares was not required to effect the Merger pursuant to the
applicable provisions of the Delaware General Corporation Law.  The Shares
issued and outstanding immediately prior to the effective time of the
Merger (other than Shares held in the treasury of the Company or owned by
any of its subsidiaries or owned by Purchaser) were converted, subject to
any appraisal rights, into the right to receive $50.00 per Share in cash,
without interest thereon.  According to Purchaser's Schedule 13D filed
October 12, 1999, upon the effective time of the Merger, Parent owned 100%
of the Shares and approximately 98.9% of the Warrants.  The Warrants
issued and outstanding immediately prior to the effective time of the
Merger and not tendered pursuant to the Offer will remain outstanding.

In connection with the Offer, Parent and Purchaser borrowed approximately
$1.2 billion pursuant to a term loan facility's credit agreement with
banks, of which pursuant to the merger, $910,000,000 became the obligation
of the Company.  A portion of the Company's borrowing has been refinanced
by the Company's issuance of EUR300,000,000 5.875% Bearer Bonds due in
November 2004. In order to avoid the foreign currency risk, the Company
has entered into a cross currency swap fixing the Euro debt in the amount
of $320,550,000, with an average U.S. dollar interest rate of 7.83733% for
5 years.






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


Financial Condition

    In September 1999, the Company entered into a merger agreement
with Dyckerhoff AG ("Dyckerhoff"). This agreement provided for the
acquisition of the Company by Dyckerhoff and was completed in
October 1999. Under the agreement, Dyckerhoff completed an all-cash
tender offer for all of the Company's outstanding common stock at a
price of $50 per share and all outstanding warrants at a price of
$81.25 per warrant. The total purchase price will be approximately
$1.2 billion, including debt assumed (See Note 8).

    As of September 30, 1999, the Company had cash and marketable
securities on hand of $97.5 million.  Due to the acquisition by
Dyckerhoff in October, the Company's $50.0 million of 7.31% senior
notes became due.  On November 3, 1999, the Company paid these
senior notes at par plus $1.9 million relating to a prepayment
penalty amount and accrued interest. The Company believes that
funds generated by operations and advances from Dyckerhoff will be
adequate to cover current working capital and capital expenditure
needs.

    During 1999, the Company purchased 1,161,000 shares of its
stock and 32,000 warrants at a cost of $39.7 million.  The 1999
purchases include 128,600 shares of stock and 4,000 warrants
purchased during the third quarter at a cost of $5.1 million. Since
the inception of its repurchase program in July 1995, the Company
has purchased a total of 7,705,100 shares and 211,400 warrants at a
cost of $200.0 million.

    Cash flows from operating activities of $69.8 million for the
nine months ended September 30, 1999 primarily reflect income from
operations and changes in working capital.  The utilization of net
operating loss carryforwards and other deferred tax assets during
the first nine months reduced cash taxes otherwise payable by $12.9
million.

    During the nine months ended September 30, 1999, investing
activities used $54.2 million, primarily representing $49.3 million
for capital expenditures and a $5.3 million advance to Kosmos
Cement Company, a partnership in which the Company owns a 25%
interest.

    Net cash outflows from financing activities of $38.3 million
for the nine months ended September 30, 1999 primarily reflect
$39.7 million for the purchase of common stock and warrants and
$3.0 million for dividends. These payments were partially offset by
proceeds of $4.3 million from the exercise of warrants.

    Working capital on September 30, 1999 was $137.1 million as
compared to $143.4 million on December 31, 1998.  Current assets
decreased $8.5 million primarily due to lower short-term
investments, offset by higher accounts and notes receivable
balances. Current liabilities decreased $2.2 million primarily due
to a decrease in accounts payables and accrued liabilities, offset
by higher income taxes payable.

    The $12.9 million decrease in the Company's long-term deferred
tax asset is due to the utilization of a portion of the tax assets
during the first nine months of 1999.  Investments in joint
ventures increased $6.7 million primarily due to a $5.3 million
advance to Kosmos Cement Company.  Net property, plant and
equipment increased $31.1 million reflecting capital expenditures,
partly offset by depreciation expense.

    The Company is subject to extensive, stringent and complex
federal, state and local laws, regulations and ordinances
pertaining to the quality and the protection of the environment
and human health and safety, requiring the Company to devote
substantial time and resources in an effort to maintain continued
compliance. Many of the laws and regulations apply to the
Company's former activities, properties and facilities as well as
its current operations. There can be no assurances that judicial
or administrative proceedings, seeking penalties or injunctive
relief, will not be brought against the Company for alleged non-
compliance with applicable environmental laws and regulations
relating to matters as to which the Company is currently unaware.
For instance, if releases of hazardous substances are discovered
to have occurred at facilities currently or previously owned or
operated by the Company, or at facilities to which the Company has
sent waste materials, the Company may be subject to liability for
the investigation and remediation of such sites. In addition,
changes to such regulations or the enactment of new regulations in
the future could require the Company to undertake capital
improvement projects or to cease or curtail certain operations or
could otherwise substantially increase the capital, operating and
other costs associated with compliance (See Note 6).

    The Company believes that it has adequately provided for costs
related to its ongoing obligations with respect to known
environmental liabilities. Expenditures for environmental
liabilities during the first nine months of 1999 did not have a
material effect on the financial condition or cash flows of the
Company.


Year 2000

    The Company has conducted a company-wide assessment of its
computer systems and operations to identify computer hardware,
software and process control systems that are not Year 2000
compliant.  The Company believes that all issues that may result
in loss of plant production have been identified and resolved by
the Company.  Expenses incurred to date have not been material,
and the Year 2000 issue has had no known effect on the Company to
date.  Future costs are not expected to be material.  Since 1990,
the Company has been replacing and upgrading its corporate and
plant computer systems, including its maintenance management
system, sales order entry system, treasury system and other
financial programs.  The Company has replaced all employee desktop
computer systems within the past several years.  Such improvements
have been made in the normal course of business.  Vendors have
assured the Company that all of these recently purchased machines
and software programs are Year 2000 compliant.

    The Company has been in communication with third parties such
as critical vendors and major service suppliers, communications
providers and banks whose system failures potentially could have a
material impact on the Company.  No single customer accounts for
more than 10% of the Company's total sales and the Company has no
material executory contracts to sell cement that extend past
December 31, 1999.  Accordingly, the Company is not canvassing its
customers as to their Year 2000 compliance.  There can be no
guarantee that customer and vendor systems will be Year 2000
compliant.  Moreover, the potential effect of such noncompliance
cannot be quantified because of the impossibility of estimating
the magnitude, duration, or ultimate impact of noncompliance by
others.

    If the Company's efforts in respect of Year 2000 problems in
its critical operations ultimately prove unsuccessful, or if it is
affected by the inability of suppliers or customers to continue
operations due to such a problem, the results of operations or
financial condition could be materially impacted.  In the event of
the failure to correct all compliance issues related to
manufacturing control systems, the plants have the ability, in
many instances, to continue operations mechanically, rather than
electronically.  However, operations at a plant would shut down if
that plant's main control center failed or if power suppliers
failed to deliver electricity due to a Year 2000 problem. Failure
of other major third parties, such as coal and gas suppliers and
railroads, to correct Year 2000 problems could also affect the
Company's business.

    The Company has developed a summary contingency plan designed
to mitigate, in part, the impact on its business of certain Year
2000 problems.  This plan, however, can not cover all
eventualities, such as a power outage.  The Company expects this
plan to be in place by the end of 1999.

Forward-Looking Statements

    This Management's Discussion and Analysis of Financial
Condition and Results of Operations and other sections of this Form
10-Q contain forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the
Securities Exchange Act of 1934.  These forward-looking statements
are based on current expectations, estimates and projections
concerning the general state of the economy and the industry and
market conditions in certain geographic locations in which the
Company operates.  Words such as "expects", "anticipates",
"intends", "plans", "believes", "estimates" and variations of such
words and similar expressions are intended to identify such
forward-looking statements.  These statements are not guarantees of
future performance and involve certain risks, uncertainties and
assumptions which are difficult to predict. Therefore, actual
results and outcomes may differ materially from what is expressed
or forecasted in such forward-looking statements. The Company
undertakes no obligation to update publicly any forward-looking
statements as a result of new information, future events or other
factors.

    The Company's business is cyclical and seasonal, the effects of
which cannot be accurately predicted. Risks and uncertainties
include changes in general economic conditions (such as changes in
interest rates), changes in economic conditions specific to any one
or more of the Company's markets (such as the strength of local
real estate markets and the availability of public funds for
construction), adverse weather, unexpected operational
difficulties, changes in governmental and public policy including
increased environmental regulation, the outcome of pending and
future litigation, the successful negotiation of labor contracts,
unforeseen operational difficulties including difficulties relating
to the construction and installation of improvements to property,
plant and equipment, financial losses due to Year 2000 computer
problems, and the continued availability of financing in the
amounts, at the times, and on the terms required to support the
Company's future business.  Other risks and uncertainties could
also affect the outcome of the forward-looking statements.



Results of Operations

    Consolidated net sales of $112.9 million and $281.6 million
during the three and nine months ended September 30, 1999 were $8.9
million and $22.1 million, respectively, higher than the comparable
prior-year results. Portland cement shipments for the current
quarter and nine-month periods were approximately 8% and 7%,
respectively, above the prior-year levels reflecting continued
strong demand in most markets.  Average net realized selling
prices for portland cement products for the third quarter of 1999
were consistent with the comparable prior-year period third  and
approximately 1% higher for the nine months ended September 30,
1999 as compared to 1998.

    Gross profit from the Company's cement and ready-mixed concrete
operations of $45.0 million and $101.7 million for the three and
nine months ended September 30, 1999 were $1.5 million and $8.1
million, respectively, higher than the comparable 1998 periods.
The increase in gross profit reflects higher overall shipments and
greater cement production for the three and nine months ended
September 30, 1999.

    Included in the calculation of gross profit are sales less cost
of sales including depreciation related to cost of sales (which
excludes depreciation on office equipment, furniture and fixtures
which are not related to the cost of sales).

    The Company's operations are seasonal and, consequently, the
interim results are not indicative of the results to be expected
for the full year.

    Pre-tax income from joint ventures of $2.9 million and $6.5
million during the three and nine months ended September 30, 1999
reflects the results of the Kosmos Cement Company, a partnership in
which the Company has a 25% interest.  The results for the three
and nine months ended September 30, 1999 were $0.1 million and $0.5
million, respectively, higher than the comparable prior-year
periods. The increase is primarily due to higher shipments for both
1999 periods.

    Other income of $3.0 million and $6.5 million during the three
and nine months ended September 30, 1999 decreased $0.5 million and
$2.7 million, respectively, from the comparable 1998 periods. For
both 1999 periods, the decrease is primarily due to less interest
income reflecting lower short-term investment balances.  During the
third quarter 1999, the Company received $1.4 million for a bond
assessment rebate on a parcel of real estate. In addition, other
income for the first nine months of 1998 included a gain of $3.3
million, $1.8 million of which was received during the third
quarter, on the sale of surplus parcels of real estate.

    Interest expense of $0.3 million and $1.6 million during the
three and nine months ended September 30, 1999 were $0.3 million
and $0.2 million, respectively, lower than the prior-year period
expense. Capitalized interest was $0.7 million and $1.3 million for
the three and nine months ended September 30, 1999 and $0.4 million
and $1.1 million for the comparable prior-year periods.

    The income tax expense of $15.2 million and $31.8 million
during the three and nine months ended September 30, 1999
increased $0.6 million and $2.1 million, respectively, over the
prior-year expense due to higher pre-tax earnings in both 1999
periods.

    Net income of $29.8 million during the third quarter of 1999
was $1.1 million higher than the prior-year results. On a per share
basis, basic and diluted earnings for the third quarter of 1999
were $1.54 and $1.25, respectively, compared to $1.39 and $1.08,
respectively, for 1998.  This improvement is primarily due to
higher results for the cement operations reflecting higher average
selling prices and increased shipments for portland cement products
and lower shares outstanding. These favorable results were partly
offset by higher cost of sales, higher income tax expense due to
higher pre-tax earnings and lower other income.

    Net income of $62.4 million during the first nine months of
1999 was $4.1 million higher than the prior-year results. On a per
share basis, basic and diluted earnings for the first nine months
of 1999 were $3.17 and $2.58, respectively, compared to $2.75 and
$2.15, respectively, for 1998.  This improvement is primarily due
to higher results for the cement operations reflecting higher
average selling prices and increased shipments for portland cement
products and lower shares outstanding.  These favorable results
were partly offset by higher cost of sales, higher income tax
expense due to higher pre-tax earnings and lower other income.
