3.  ACQUISITIONS

In the first quarter of 1996, the Company purchased substantially all of the 
assets of two window distribution facilities in Texas.  In the second quarter 
of 1996, the Company purchased a truss plant in Utah.  The total purchase 
price for these facilities was $3,347,000.  On October 1, 1996, the Company 


<PAGE>

purchased a center located in Utah which sells pre-hung doors and other 
building materials.



4.  PUBLIC STOCK OFFERING

In the second quarter of 1996, the Company sold 2,300,000 shares of its 
previously unissued common stock.  The price of the stock to the public was 
$18.00 per share.  The proceeds from these offerings, less underwriting and 
other issuance costs, were used principally to reduce debt.

5.  EXTRAORDINARY ITEM

A portion of the proceeds of the public stock offering discussed above were 
used to redeem the 10% unsecured senior subordinated notes. In connection 
with this planned redemption, the Company wrote off the related deferred loan 
costs. These write-offs are included in the 1996 statement of income as an 
extraordinary item of $342,000, net of tax benefits.

</TABLE>


THIRD QUARTER OF 1996 COMPARED TO THE THIRD QUARTER OF 1995
-----------------------------------------------------------

Net sales for the three months ended September 30, 1996 were $206.5 million 
up 16% from the third quarter of 1995 when sales were $178.5 million.  The 
growth in net sales resulted from an increase from the third quarter of 1995 
in sales at facilities that operated for at least two months in both the 
third quarter of 1995 and the third quarter of 1996 ("Same-Store Sales").  
Sales in the 1996 period were positively affected by higher commodity wood 
product prices.  The price increase contributed to an overall price inflator 
of 6%, the effect of which increased sales by approximately $10.7 million.  
Excluding price inflation, same-store sales increased 10%.

Gross profit as a percentage of sales declined slightly to 21.5% in the third 
quarter of 1996 from 22.0% in the third quarter of 1995.  The decrease was a 
result of a competitive environment, along with our efforts to substantially 
increase market share in certain markets.  Also, margins decreased as a result

<PAGE>

of a higher percentage of sales to professional contractors (which generally 
carry lower margins) in the 1996 period compared to 1995.

Selling, general and administrative (SG&A) expense, was $34.8 million in the 
third quarter of 1996 as compared to $31.2 million in 1995, but decreased as 
a percentage of net sales from 17.5% in 1995 to 16.8% in 1996. This reduction 
was somewhat due to improvements in costs associated with integrating the 14 
building materials centers acquired in 1994 and 1995.

Interest expense of $2.3 million in the third quarter of 1996 decreased from 
$2.9 million in the same period of 1995.  This decrease was due to a 
reduction in the Company's outstanding debt in the third quarter of 1996 with 
the proceeds of an equity offering.

Income taxes were provided at estimated annual effective tax rates of 39.5% 
and 38.9% for the periods ended September 30, 1996 and September 30, 1995, 
respectively.  This increase in the effective tax rate from 1995 was 
primarily due to book/tax differences in accounting for goodwill in 
connection with acquisitions in 1994 and 1995.

As a result of the foregoing factors, net income increased by $1.2 million, 
or 34% to $4.6 million or 2.2% of net sales in the third quarter of 1996, as 
compared to $3.4 million or 1.9% of net sales, in the third quarter of 1995.

FIRST NINE MONTHS OF 1996 COMPARED WITH THE FIRST NINE MONTHS OF 1995
---------------------------------------------------------------------

Net sales for the nine months ended September 30, 1996 were $547.1 million up 
18% from the first nine months of 1995 when sales were $465.2 million.  The 
growth in net sales resulted from an increase of 12% in Same-Store Sales, 
over the first nine months of 1995 and from the acquisition of new building 
materials centers.  Sales in the 1996 period were positively affected by 
higher commodity wood product prices.  The price increase contributed to an 
overall price inflator of 3% the effect of which increased sales by 
approximately $13.7 million.


<PAGE>

Gross profit as a percentage of sales declined slightly to 21.9% in the first 
nine months of 1996 from 22.3% in the first nine months of 1995.  The 
decrease was a result of a competitive environment, along with our efforts to 
substantially increase market share in certain markets.  Also, margins 
decreased as a result of a higher percentage of sales to professional 
contractors (which generally carry lower margins) in the 1996 period compared 
to 1995.

Selling, general and administrative (SG&A) expense, was $97.5 million in the 
first nine months of 1996 as compared to $86.6 million in 1995, but decreased 
as a percentage of net sales from 18.6% in 1995 to 17.8% in 1996. This 
reduction was somewhat due to improvements in costs associated with 
integrating the 14 building materials centers acquired in 1994 and 1995.

Interest expense increased to $8.3 million in the first nine months of 1996 
from $7.9 million in the same period of 1995, primarily due to additional 
borrowings to finance working capital growth and acquisitions.

Other income increased to $1.3 from $1.2 in the 1995 period.  This increase 
in 1996 was the result of a gain of $395,000 on the sale of real property in 
1996 made available by the consolidation of operations in the Puget Sound 
market.

Income taxes were provided at estimated annual effective tax rates of 39.5% 
and 38.9% for the nine month period ended September 30, 1996 and September 
30, 1995, respectively.  This increase in the effective tax rate from 1995 
was primarily due to book/tax differences in accounting for goodwill in 
connection with acquisitions in 1994 and 1995.

As a result of the foregoing factors, net income before an extraordinary 
item, increased by $2.8 million, or 44% to $9.2 million, or 1.7% of net sales 
in the first nine months of 1996, as compared to $6.4 million, or 1.4% of net 
sales, in the first nine months of 1995.

The Company redeemed the 10% unsecured senior subordinated notes with the net 
proceeds of the recent equity offering. In connection with this redemption, 
the Company wrote off the related deferred loan cost.  These write-offs were 


<PAGE>

recorded as an extraordinary charge of $342,000, after tax.  This charge 
reduced net income for the nine months ended September 30, 1996 to $8.9 
million or 1.6% 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 price to the public was $18.00 per 
share. The proceeds of this offering, less underwriting and estimated other 
issuance costs, was approximately $38.5 million. The proceeds were 
temporarily used to reduce the revolving credit agreement balance in the 
third quarter of 1996.  The Company also retired the $20 million of 10% 
unsecured senior subordinated notes.

At September 30, 1996 the Company had $95.4 million of long-term debt 
outstanding, consisting of $75.0 million of term borrowings under fixed rate 
notes, $18.7 million of variable rate borrowings under the revolving credit 
agreement and $1.7 million of fixed rate borrowings under a note.

For the nine months ended September 30 1996, the Company provided $4.7 
million of cash from operating activities.  Working capital increased from 
$100.2 million at December 31, 1995 to $116.3 million at September 30, 1996, 
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 September 30, 1996 of $51.3 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 current anticipated requirements.
