                              LOAN AGREEMENT


     THIS AMENDED AND RESTATED LOAN AGREEMENT ("Agreement") is made and 
entered into as of  June 1, 1998 by and between Simpson Manufacturing Co., 
Inc., a California Corporation ("Borrower") and UNION BANK OF CALIFORNIA, 
N.A. ("Bank").  This Agreement amends and restates in its entirety that 
certain loan agreement dated January 14, 1997 between Bank and Borrower.

SECTION 1.  THE LOAN

     1.1.1   The Revolver-To-Term Loan.  Bank will loan to Borrower an 
amount not to exceed Thirteen Million Eight Hundred Thousand Dollars 
($13,800,000) outstanding in the aggregate at any one time (the 
"Revolver-To-Term Loan").  Borrower may borrow, repay and reborrow all or 
part of the Revolver-To-Term Loan in accordance with the terms of the 
Revolver-To-Term Note.  All borrowings of the Revolver-To-Term Loan must be 
made before  June 30, 2000 at which time all unpaid principal under the 
Revolver-To-Term Loan shall be converted to a fully amortizing loan as set 
forth in subsection 1.1.3.  The Revolver-To-Term Loan shall be evidenced by a 
promissory note (the "Revolver-To-Term Note") on the standard form used by 
Bank for commercial loans.  Bank shall enter each amount borrowed and repaid 
in Bank's records and such entries shall be deemed to be the amount of the 
Revolver-To-Term Loan outstanding.  Omission of Bank to make any such entries 
shall not discharge Borrower of its obligation to repay in full with interest 
all amounts borrowed.

     1.1.2  The Standby L/C Sublimit.  As a sublimit to the Revolving Loan, 
Bank shall issue, as Borrower may request from time to time for the account 
of Borrower, one or more irrevocable, standby or commercial letters of credit 
(individually, an "L/C" and collectively, the "L/Cs").  All such L/Cs shall 
be drawn on such terms and conditions as are reasonably acceptable to Bank. 
The aggregate amount available to be drawn under all outstanding L/Cs and the 
aggregate amount of unpaid reimbursement obligations under drawn L/Cs shall 
not exceed Four Million Dollars ($4,000,000.00) and shall reduce, dollar for 
dollar, the maximum amount available under the  Revolving-To-Term-Loan.  Each 
L/C shall be governed by the terms of (and Borrower agrees to execute) Bank's 
standard form for L/C applications and reimbursement agreements. No L/C may 
be issued for a period exceeding 12 months, and no L/C shall expire after 
June 30, 2000. At Borrower's request, Bank will issue  L/C's on behalf of 
Borrower's subsidiaries, including but not limited to: 1) Simpson Strong-Tie 
Company, Inc.; 2) Simpson Dura-Vent Company, Inc. and 3) Simpson Strong-Tie, 
International  Inc., so long as the Borrower executes the Bank's standard 
form for L/C applications and reimbursement agreement.

Borrower currently maintains an outstanding L/C in the amount of Four Hundred 
Seventy Thousand Pounds Sterling (GBP470,000) maturing January 1, 1999 and an 
L/C in the amount of Three Hundred Thirty Three Thousand Nine Hundred Ninety 
Eight Dollars and fifty cents ($333,998.50)  maturing on June 1, 1999. These 
L/C's shall now be considered as utilization under the L/C sublimit.


     1.1.3  The Term Loan.  At Borrower's request and solely to repay the 
Revolver-To-Term Loan, Bank will loan to Borrower the sum outstanding at the 
maturity of the Revolver-To-Term Loan in one disbursement on or before June 
1, 2000 (the "Term Loan").  In the event of a prepayment of principal of the 
Term Loan and payment of any resulting fees, any prepaid amounts shall be 
applied to the scheduled principal payments in the reverse order of their 
maturity.  The Term Loan shall be evidenced by the Revolver-To-Term Note.

     1.2  Terminology.

          As used herein the word "Loan" shall mean, collectively, all the

Loan shall bear interest at the rate(s) specified in the Note and selected by 
Borrower.

December 30, 1998, or the earlier termination of the Loan, Borrower shall pay 
to Bank a fee of one eighth of one percent (.125%) per year on the unused

     1.6  Stand-by Letter of Credit Fees.  Borrower agrees to pay Bank three
