                   SIMPSON MANUFACTURING CO., INC. AND SUBSIDIARIES
                 NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


1.  Basis of Presentation

Interim Period Reporting

The accompanying unaudited interim condensed consolidated financial 
statements have been prepared pursuant to the rules and regulations for 
reporting on Form 10-Q. Accordingly, certain information and footnotes 
required by generally accepted accounting principles have been condensed or 
omitted. These interim statements should be read in conjunction with the 
consolidated financial statements and the notes thereto included in Simpson 
Manufacturing Co., Inc.'s (the "Company's") 1995 Annual Report on Form 10-K 
(the "1995 Annual Report").

The unaudited quarterly condensed consolidated financial statements have 
been prepared on the same basis as the audited annual consolidated 
financial statements, and in the opinion of management, contain all 
adjustments (consisting of only normal recurring adjustments) necessary to 
present fairly the financial information set forth therein, in accordance 
with generally accepted accounting principles. The year-end condensed 
consolidated balance sheet data was derived from audited financial 
statements, but does not include all disclosures required by generally 
accepted accounting principles. The Company's quarterly results may be 
subject to fluctuations. As a result, the Company believes the results of 
operations for the interim periods are not necessarily indicative of the 
results to be expected for any future period.

Net Income Per Common Share

Net income per common share is computed based upon the weighted average 
number of common shares outstanding. Common equivalent shares, using the 
treasury stock method, are included in the per-share calculations for all 
periods since the effect of their inclusion is dilutive.

The number of shares used in computing primary and fully diluted net income 
per common share did not differ materially for the three and nine months 
ended September 30, 1996 and 1995.


2.  Trade Accounts Receivable

Trade accounts receivable consist of the following:


                                                          SEPTEMBER 30,             DECEMBER 31,

3.  Inventories  The components of inventories consist of the following:

                                                  ============     ============     ============


Approximately 96% of the Company's inventories are valued using the LIFO 
(last-in, first-out) method. Because inventory determination under the LIFO 
method is only made at the end of each year based on the inventory levels 
and costs at that time, interim LIFO determinations must necessarily be 
based on management's estimates of expected year-end inventory levels and 
costs. Since future estimates of inventory levels and costs are subject to 
change, interim financial results reflect the Company's most recent 
estimate of the effect of inflation and are subject to final year-end LIFO 
inventory amounts. At September 30, 1996 and 1995, and December 31, 1995, 
the replacement value of LIFO inventories exceeded LIFO cost by 
approximately $2,602,000, $3,594,000 and $4,178,000, respectively.

6.  Commitments and Contingencies

Note 10 to the consolidated financial statements in the Company's 1995 
Annual Report provides information concerning commitments and contingencies 
relating to pending or possible claims, legal actions and proceedings 
against the Company and its subsidiaries. Management believes that the 
final resolution of these matters, individually or in the aggregate, is not 
expected to have a material adverse effect on the financial position of the 
Company.


Item 2. Management's Discussion and Analysis of Financial Condition and 
Results of Operations.

The following is a discussion and analysis of the consolidated financial 
condition and results of operations for the Company for the three and nine 
months ended September 30, 1996 and 1995. The following should be read in 
conjunction with the interim Condensed Consolidated Financial Statements 
and related Notes appearing elsewhere herein. 

Results of Operations for the Three Months Ended September 30, 1996, 
Compared with the Three Months Ended September 30, 1995

Net sales increased 21.4% from the third quarter of 1995 to the third 
quarter of 1996. The increase reflected solid growth throughout the United 
States, although, sales in California increased at a rate slower than the 
average growth rate. Simpson Strong-Tie's sales increased 23.8% while 
Simpson Dura-Vent's sales increased 13.4%. Sales to dealer distributors 
were the fastest growing connector sales channel, while contractor 
distributor and homecenter sales growth slowed somewhat. The sales growth 
rate of engineered wood products and seismic and high wind products led 
Simpson Strong-Tie sales with above average increases, while Simpson Dura-
Vent sales of Direct-Vent products, sold both to OEMs and through 
distributors, continued to experience strong growth. Third quarter sales 
were also positively influenced by sales at the businesses acquired in the 
second half of 1995. The acquisitions during the last year accounted for 
1.6% of the Company's 1996 third quarter sales.

Income from operations increased 40.7% from $7,621,797 in the third quarter 
of 1995 to $10,724,722 in the third quarter of 1996. This increase was 
primarily due to higher gross margins, partially offset by higher general 
and administrative expenses as a percentage of sales. Selling expenses 
increased 23.2% in total from $4,001,779 in the third quarter of 1995 to 
$4,929,448 in the third quarter of 1996. General and administrative 
expenses increased 28.5% from $5,472,251 in the third quarter of 1995 to 
$7,033,766 in the third quarter of 1996. This increase was primarily due to 
increased cash profit sharing, as a result of higher operating profit, and 
higher personnel and other overhead costs. Interest income increased to 
$175,048 in the third quarter of 1996 as a result of the increased cash 
balances. The effective tax rate increased from 38.2% in the third quarter 
of 1995 to 41.4% in the third quarter of 1996, primarily due to the 
recognition of lower effective state tax rates in the third quarter of 
1995.

Results of Operations for the Nine Months Ended September 30, 1996, 
Compared with the Nine Months Ended September 30, 1995

Net sales increased 22.2% during the first nine months of 1996 as compared 
to the first nine months of 1995. The increase reflected solid growth 
throughout the United States, although sales in California increased at a 
rate slower than the average growth rate. Simpson Strong-Tie's sales 
increased 22.7% while Simpson Dura-Vent's sales increased 20.4%. The sales 
growth rate of engineered wood products and seismic and high wind products 
led Simpson Strong-Tie sales with above average increases, while Simpson 
Dura-Vent sales of Direct-Vent products, sold both to OEMs and through 
distributors, continued to experience strong growth. Year to date sales 
were also positively influenced by sales at the businesses acquired in the 
second half of 1995. The acquisitions during the last year accounted for 
1.6% of the Company's 1996 year to date sales.

Income from operations increased 34.9% from $18,349,455 in the first nine 
months of 1995 to $24,750,192 in the first nine months of 1996. This 
increase was primarily due to higher gross margins, partially offset by 
higher general and administrative expenses as a percentage of sales as well 
as a small relative increase in selling expense. Selling expenses increased 
25.5% in total from $11,874,332 in the first nine months of 1995 to 
$14,902,126 in the first nine months of 1996. General and administrative 
expenses increased 26.9% from $14,493,020 in the first nine months of 1995 
to $18,387,692 in the first nine months of 1996. This increase was 
primarily due to increased cash profit sharing, as a result of higher 
operating profit, and higher personnel and other overhead costs. Interest 
income increased to $325,931 in the first nine months of 1996 as a result 
of the increased cash balances. The effective tax rate increased from 40.1% 
in the first nine months of 1995 to 40.9% in the first nine months of 1996, 
primarily due to the recognition of lower effective state tax rates in the 
third quarter of 1995.


In October, Simpson Strong-Tie's quality management system was recommended 
for ISO9000 registration by a third party registration organization. 
Simpson Strong-Tie is the Company's largest subsidiary and, to the 
Company's knowledge, no other U.S. company in the connector industry has 
been ISO9000 registered. Management believes that this recommendation 
reflects the Company's on-going commitment to quality.

The Company has committed to purchase or has leased additional space to 
increase its capacity. Simpson Strong-Tie has expanded its research and 
development and marketing support facilities by leasing a 48,000 square 
foot building in San Leandro, California, and has moved its Jacksonville, 
Florida, warehouse into a new leased facility with approximately twice the 
square footage of its old facility. The planned expansion of the company 
owned warehouse in McKinney, Texas, has commenced. This expansion will add 
approximately 60,000 square feet to the existing structure. In addition, 
the Company has agreed to purchase a 30,500 square foot building which it 
currently leases from an unrelated party at its facility in Brea, 
California.

Liquidity and Sources of Capital

As of September 30, 1996, working capital was $67.4 million as compared to 
$50.8 million at September 30, 1995, and $52.0 million at December 31, 
1995. The principal components of the increase in working capital from 
December 31, 1995, include an increase in trade accounts receivable and 
inventories, which increased to support the higher level of sales. 
Partially offsetting these increases were increases in trade accounts 
payable, accrued cash profit sharing and commissions, and income taxes 
payable, as a result of higher operating and taxable income, respectively. 
This increase in working capital combined with net income and noncash 
expenses, such as depreciation and amortization, resulted in the increase 
in cash and cash equivalents of $19.0 million from operating activities. As 
of September 30, 1996, the Company had unused credit facilities available 
of approximately $20.0 million.

In its investing activities, the Company used $4.3 million in cash to 
purchase capital equipment, a rate substantially below that of the first 
nine months of 1995. The Company has increased its purchases of capital 
equipment in the third quarter of 1996 in order to expand its capacity and 
anticipates additional expansion during the last quarter of 1996 and into 
1997. These plans include the purchase of the building at its Brea facility 
and additional production equipment needed to meet the expected demand.

Financing activities provided an additional $0.4 million in cash primarily 
as a result of the issuance of Common Stock upon the exercise of stock 
options by current and former employees. There were no borrowings 
outstanding on long-term debt as of September 30, 1996.

The Company believes that cash generated by operations and borrowings 
available under its existing credit agreements will be sufficient for the 
Company's working capital needs and planned capital expenditures through 
the remainder 1996 and into 1997. Depending on the Company's future growth, 
it may become necessary to secure additional sources of financing.
