4.  EARNINGS PER SHARE

     In February 1997, the Financial Accounting Standards Board issued 
Statement 128, EARNINGS PER SHARE, which will be implemented in the fourth 
quarter of 1997. Primary earnings per share will be replaced with basic 
earnings per share and fully diluted earnings per share will be renamed 
diluted earnings per share, neither of which will be significantly different 
than previously reported primary and fully diluted earnings per share.  All 
previously reported amounts will be restated.

SECOND QUARTER OF 1997 COMPARED TO THE SECOND QUARTER OF 1996

Net sales for the three months ended June 30, 1997 were $190.6 million down 
1% from the second quarter of 1996 when sales were $193.0 million.  The 
decrease in net sales resulted from a 3 percent decrease from the second 
quarter of 1996 in sales at facilities that operated for at least two months 
in both the second quarter of 1996 and the second quarter of 1997 
("Same-Store Sales").  Sales decreased due to unusually wet weather 
conditions in Texas and lower building permit activity in the majority of its 
10-state market area.  Sales in the 1997 period were not significantly 
impacted by commodity wood product prices.

Gross profit as a percentage of sales increased to 22.8% in the second quarter
of 1997 from 21.9% in the second quarter of 1996, primarily as a result of on
going efforts by the Company to improve margins through its increased focus on
value-added products, such as roof trusses, pre-hung doors and pre-assembled
windows.


                          This is Page 9 of 17 Pages

Selling, general and administrative (SG&A) expense, was $35.8 million in the
second quarter of 1997 as compared to $33.1 million in 1996, and increased as a
percentage of net sales from 17.1% in 1996 to 18.8% in 1997.  The Company
believes this increase was partially due to inclement weather in Texas which
made it difficult to manage payroll expenses in that state and increases in
value-added sales that carry higher SG&A expenses. 

Interest expense of $2.4 million in the second quarter of 1997 decreased from
$3.0 million in the same period of 1996, primarily due to less debt outstanding
in the second quarter of 1997 compared to the second quarter of 1996.

Income taxes were provided at estimated annual effective tax rates of 39.5% for
the periods ended June 30, 1997 and June 30, 1996.

As a result of the foregoing factors, net income before extraordinary item
decreased by $412,000, or 10.6% to $3,460,000, or 1.8% of net sales in the
second quarter of 1997, as compared to $3,872,000, or 2.0% of net sales, in the
second quarter of 1996.

In the second quarter of 1996, the Company obligated itself to redeem, with the
net proceeds of the recent equity offering, the 10% unsecured senior
subordinated notes early in the third quarter of 1996.  In connection with this
planned redemption, the Company wrote off the related deferred loan cost.  These
write-offs were recorded as an extraordinary charge of $342,000 in the second
quarter.  This charge reduced net income to $3,530,000 or 1.8% of sales.

FIRST SIX MONTHS OF 1997 COMPARED WITH THE FIRST SIX MONTHS OF 1996

Net sales for the six months ended June 30, 1997 were $337.4 million down 1% 
from the first half of 1996 when sales were $340.6 million.  The decrease in 
net sales resulted from a decrease of 3% in Same-Store Sales, over the first 
six months of 1996 partially offset by the acquisition of new building 
materials centers, unusually wet weather conditions in Texas and lower 
building permit activity in the majority of its 10-state market area.  Sales 
in the 1997 period were positively affected by

                          This is Page 10 of 17 Pages

<PAGE>

slightly higher commodity wood product prices.  The price increase 
contributed to an overall price inflator of 2% the effect of which increased 
sales by approximately $5.3 million.  Excluding price inflation, same-store 
sales decreased 5%.

Gross profit as a percentage of sales improved to 23.1% in the first half of
1997 from 22.1% in the first six months of 1996, primarily as a result of on
going efforts by the Company to improve margins through its increased focus on
value-added products, such as roof trusses, pre-hung doors and pre-assembled
windows.

Selling, general and administrative (SG&A) expense, was $67.7 million in the 
first six months of 1997 as compared to $62.7 million in 1996, and increased 
as a percentage of net sales to 20.1% in 1997 from 18.4% in 1996.  The 
Company believes this increase was partially due to inclement weather in 
Texas which made it difficult to manage payroll expenses in that state, 
acquisition costs, and increases in value-added sales that carry higher SG&A 
expenses. 

Interest expense decreased to $4.5 million in the first six months of 1997 from
$6.0 million in the same period of 1996, primarily due to less debt outstanding
in the six months of 1997 compared to the first six months of 1996.

Income taxes were provided at estimated annual effective tax rates of 39.5% for
the six month period ended June 30, 1997 and June 30, 1996.  

As a result of the foregoing factors, net income before extraordinary item,
decreased by $706,000, or 15.3% to $3,916,000, or 1.2% of net sales in the first
half of 1997, as compared to $4,622,000, or 1.4% of net sales, in the first six
months of 1996.

In the second quarter of 1996, the Company obligated itself to redeem, with the
net proceeds of the recent equity offering, the 10% unsecured senior
subordinated notes early in the third quarter of 1996.  In connection with this
planned redemption, the Company wrote off the related deferred loan cost.  These
write-offs were recorded as an extraordinary charge of $342,000 in the


                          This is Page 11 of 17 Pages


<PAGE>

second quarter of 1996.  This charge reduced net income for the six months 
ended June 30, 1996 to $4,280,000 or 1.3% of sales.


LIQUIDITY AND CAPITAL RESOURCES

In the second quarter of 1996, the Company sold 2,300,000 shares of previously
unissued common stock.  The net proceeds of this offering of $38.5 million, less
underwriting and estimated other issuance costs, were used to retire the $20
million of 10% unsecured senior subordinated notes in the third quarter of 1996
and reduce the debt under the revolving credit agreement.

At June 30, 1997 the Company had $100.1 million of long-term debt outstanding,
consisting of $76.1 million of term borrowings under fixed rate notes, and $24.0
million of variable rate debt under the revolving credit agreement.

In the first half of 1997, the Company generated $4.1 million of cash from
operating activities.  Working capital increased from $110.5 million at December
31, 1996 to $120.8 million at June 30, 1997, due primarily to the seasonality in
the Company's accounts receivable and inventories.

Based on its ability to generate cash from operations and the available
borrowing capacity at June 30, 1997 of $46.0 million under the revolving credit
agreement (availability of which is subject to the satisfaction of certain
customary borrowing conditions), the Company believes it will have sufficient
funds to meet its currently anticipated requirements.

NEW ACCOUNTING STANDARD

In February 1997, the Financial Accounting Standards Board issued Statement 128,
EARNINGS PER SHARE, which will be implemented in the fourth quarter of 1997. 
Primary earnings per share will be replaced with basic earnings per share and
fully diluted earnings per share will be renamed diluted earnings per share,
neither of which will be significantly different than previously reported
primary and fully diluted earnings per share.  All previously reported amounts
will be restated.
