              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") 1998 Annual Report on
Form 10-K (the "1998 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.

Certain prior year amounts have been reclassified to conform to the 1999
presentation with no effect on net income as previously reported.

Net Income Per Common Share

Basic 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 diluted per-share
calculations for all periods when the effect of their inclusion is
dilutive.

The following is a reconciliation of basic earnings per share ("EPS") to
diluted EPS:

Approximately 91% 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 LIFO and are subject to
adjustment based upon final year-end inventory amounts. At June 30, 1999
and 1998, and December 31, 1998, the replacement value of LIFO inventories
exceeded LIFO cost by approximately $79,000, $566,000 and $359,000,
respectively.

As of June 30, 1999, the Company had three outstanding standby letters of
credit. Two of these letters of credit, in the aggregate amount of
$1,166,748, are used to support the Company's self-insured workers'
compensation insurance requirements. The third, in the amount of $740,274,
is used to guarantee performance on the Company's leased facility in the
UK. Other notes payable represent debt associated with foreign businesses.


6.  Commitments and Contingencies

Note 9 to the consolidated financial statements in the Company's 1998
Annual Report provides information concerning commitments and
contingencies. From time to time, the Company is involved in various legal
proceedings and other matters arising in the normal course of business.


7.  Segment Information

The Company is organized into two primary segments. The segments are
defined by types of products manufactured, marketed and distributed to the
Company's customers. The two product segments are connector products and
venting products. These segments are differentiated in several ways,
including the types of materials used, the production process, the
distribution channels used and the applications in which the products are
used. Transactions between the two segments were immaterial for each of
the periods presented.

The following table illustrates certain measurements used by management to
assess the performance of the segments described above as of or for the
three and six months ended:

Cash collected by the Company's subsidiaries is routinely transferred into
the Company's cash management accounts and, therefore, has been included
in the total assets of the segment entitled "All other." Cash and cash
equivalent balances in this segment were approximately $36,387,000 and
$19,089,000 as of June 30, 1999 and 1998, respectively.



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

Certain matters discussed below are forward-looking statements that
involve risks and uncertainties, certain of which are discussed in this
report and in other reports filed by the Company with the Securities and
Exchange Commission. Actual results might differ materially from results
suggested by any forward-looking statements in this report.

The following is a discussion and analysis of the consolidated financial
condition and results of operations for the Company for the three months
ended June 30, 1999 and 1998. 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 June 30, 1999,
Compared with the Three Months Ended June 30, 1998

Sales increased 18.3% in the second quarter of 1999 as compared to the
second quarter of 1998. The increase reflected sales growth throughout the
United States, particularly in California. Sales in most of the Company's
international markets continued to grow. Simpson Strong-Tie's second
quarter sales increased 17.6% over the same quarter last year, while
Simpson Dura-Vent's sales increased 21.7%. Homecenters were the fastest
growing connector sales channel. The sales increase was broad based across
all of Simpson Strong-Tie's major product lines. Anchoring Systems
products had the highest growth rate in sales and the Company's new
Strong-Wall product line also contributed to the increased sales. Sales of
most of Simpson Dura-Vent's major product lines increased compared to the
second quarter of 1998, led by above average growth rates for its Direct-
Vent and chimney product lines.

Income from operations increased 18.8% from $13,987,166 in the second
quarter of 1998 to $16,622,567 in the second quarter of 1999 as a result
of higher sales and gross margins and lower general and administrative
costs as a percentage of sales. Gross margins increased from 41.1% in the
second quarter of 1998 to 41.4% in the second quarter of 1999 primarily
due to better absorption of fixed overhead costs as a result of the
increased production. Selling expenses increased 31.2% from $6,129,472 in
the second quarter of 1998 to $8,041,724 in the second quarter of 1999.
The increase was primarily due to higher promotional expenses as well as
higher costs related to an increase in the number of sales and marketing
personnel. General and administrative expenses increased 10.8% from
$8,916,134 in the second quarter of 1998 to $9,878,575 in the second
quarter of 1999 primarily due to increased cash profit sharing resulting
from higher operating income. The effective tax rate was 40.3% in the
second quarter of 1999, a slight decrease from the second quarter of 1998.


Results of Operations for the Six Months Ended June 30, 1999,
Compared with the Six Months Ended June 30, 1998

Sales increased 21.8% in the first half of 1999 as compared to the first
half of 1998. The increase reflected sales growth throughout the United
States, particularly in California and in the southeastern portion of the
country. Sales in most of the Company's international markets continued to
grow. Simpson Strong-Tie's sales through June 30, 1999, increased 21.5%
over the same period in the prior year, while Simpson Dura-Vent's sales
increased 23.4%. Homecenters were the fastest growing connector sales
channel. The sales increase was broad based across all of Simpson Strong-
Tie's major product lines. Anchoring Systems products had the highest
growth rate in sales. Sales of all of Simpson Dura-Vent's major product
lines increased in the first half of 1999 compared to the same period in
1998, led by above average growth rates for its Direct-Vent and chimney
product lines.

Income from operations increased 24.6% from $23,314,289 in the first half
of 1998 to $29,051,613 in the first half of 1999 as a result of higher
sales and gross margins and lower general and administrative costs as a
percentage of sales. Gross margins increased from 39.2% in the first half
of 1998 to 39.8% in the first half of 1999 primarily due to better
absorption of fixed overhead costs as a result of the increased
production. Selling expenses increased 35.6% from $11,754,247 in the first
half of 1998 to $15,939,530 in the first half of 1999. The increase was
primarily due to higher promotional expenses as well as higher costs
related to an increase in the number of sales and marketing personnel.
General and administrative expenses increased 13.5% from $15,780,630 in
the first half of 1998 to $17,917,336 in the first half of 1999 primarily
due to increased cash profit sharing resulting from higher operating
income. The effective tax rate was 40.2% in the first half of 1999, a
slight decrease from the first half of 1998.



Liquidity and Sources of Capital

As of June 30, 1999, working capital was $127.2 million as compared to
$92.8 million at June 30, 1998, and $105.6 million at December 31, 1998.
The principal components of the increase in working capital from December
31, 1998, were increases in the Company's trade accounts receivable and
inventories totaling approximately $27.2 million, primarily due to higher
sales levels. In addition, a reduction in income taxes payable resulting
from the exercise of stock options by employees of the Company, most of
which occurred in the second quarter, increased working capital by
approximately $4.6 million. Partially offsetting these increases were
increases in trade accounts payable, accrued profit sharing trust
contributions and accrued cash profit sharing. These accounts increased an
aggregate of approximately $8.1 million. The balance of the change in
working capital was due to the fluctuation of various other asset and
liability accounts. The working capital change and changes in noncurrent
assets and liabilities combined with net income and noncash expenses,
primarily depreciation and amortization, totaling approximately $23.0
million, resulted in net cash provided by operating activities of
approximately $4.9 million. As of June 30, 1999, the Company had unused
credit facilities available of approximately $21.5 million.

The Company used approximately $8.6 million in its investing activities,
primarily to purchase the capital equipment and property needed to expand
its capacity. The Company plans to continue this expansion throughout the
remainder of the year and into 2000.

Financing activities provided the Company with approximately $3.5 million
in cash. Substantially all of this cash was generated by the issuance of
stock upon the exercise of stock options by current employees and a
director of the Company.

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 of 1999 and into 2000. Depending on the Company's future
growth, it may become necessary to secure additional sources of financing.


Year 2000 Problem

The year 2000 problem is primarily the result of computer programs and
computer controlled equipment using two digits rather than four to define
the applicable year. Such software may recognize a date using "00" as the
year 1900 rather than the year 2000. This could potentially result in
system failures or miscalculations leading to disruptions in the Company's
activities or those of its significant customers, suppliers and banks.

The Company does not produce or sell any computer components, software or
electronic parts in its normal business environment and, therefore, does
not believe that it has any material risk of product liability or
obsolescence resulting from the year 2000 problem.

In 1998, the Company established a Year 2000 Committee (the "Committee")
to evaluate the extent, if any, of its year 2000 and associated problems,
to make any required changes and to establish contingency plans. The

Company's computer systems are PC based with few interfaces to other
internal systems. These systems use a date handling routine that the
Company believes to be year 2000 compliant. The Company has completed
tests of its internal software which demonstrated no significant risk from
the year 2000 problem.

The Company is also focusing on major customers, suppliers and equipment
used in its operations to assess compliance. The Committee will continue
to evaluate these areas of exposure and, where possible, will develop
contingency plans and alternative sources to avoid interruptions in the
Company's business. Nevertheless, the Company cannot give any assurance
that there will not be a material adverse effect on the Company if third
parties with whom the Company conducts business do not adequately address
the year 2000 problem and, therefore, are unable to conduct operations
without interruption.

Costs related to the year 2000 problem are funded through operating cash
flows. The Committee estimates that the costs of addressing the year 2000
problem are expected to be less than $100,000, most of which has been
spent. The Company presently expects that the total cost of achieving year
2000 compliant systems will not be material to its financial condition,
liquidity or results of operations.


Time and cost estimates are based on currently available information.
Developments that could affect estimates include, but are not limited to,
the availability and cost of trained personnel, the ability to locate and
correct all relevant computer code and systems, and the degree of
remediation success of the Company's customers, suppliers and banks in
finding and resolving their year 2000 problems.
