Amendment to the PACCAR Inc Savings Investment Plan



 Exhibit 10(q) 
 ARTICLE 15 
 CONTRIBUTION LIMITATIONS

  

	15.1	Basic Limitation 

 A
Member’s Annual Additions with respect to any calendar year shall in no event exceed his Contribution Limitation for such calendar year. 
 Effective for calendar years beginning prior to January 1, 2009, in the event that a Member’s Contribution Limitation would be exceeded, his Annual Additions shall be reduced to an amount equal
to his Contribution Limitation by reducing the components of his Annual Additions as necessary in the order in which they are listed in Section 15.4(b). Such reduction shall be made in accordance with Sections 15.2 and 15.3 (where applicable).

 Effective for calendar years beginning on and after January 1, 2009, in the event that a Member’s Contribution
Limitation would be exceeded, his Annual Additions shall be reduced to an amount equal to his Contribution Limitation by reducing the components of his Annual Additions as necessary in accordance with the correction methods specified in
Section 6.06(2) and (3) of Revenue Procedure 2008-50 or its successor. 
 In applying these rules, this Plan and any
other plan required to be aggregated with this Plan under Treas. Reg. § 1.415(f)-1 shall be treated as one plan. 
  

	15.2	Effect on Future Contributions 

 Articles 4 and 5 notwithstanding, the Salary Deferrals which a Member is permitted to contribute and his share of Company Contributions shall be reduced prospectively to the extent required by Section 15.1. The aggregate amount of the
Company Contributions that otherwise would be made under Article 5 shall be reduced accordingly. 
  

	15.3	Effect on Prior Contributions 

 Effective for calendar years beginning prior to January 1, 2009, if a Member’s Annual Additions exceeds his Contribution Limitation, then such Excess Annual Additions as are attributable to Salary Deferrals and Company
Contributions shall be eliminated as follows: 
  

	 	(a)	Excess Annual Additions attributable to Salary Deferrals, including investment gains, shall be distributed to the Member. 

  

	 	(b)	 Excess Annual Additions attributable to Company Contributions shall be transferred to a suspense account. Any earnings, appreciation or losses
attributable to the suspense account shall be allocated to such account. All amounts credited to the suspense account shall be applied to reduce Company Contributions for the next calendar year, and for succeeding













	 	 
calendar years if necessary. Such amounts shall be allocated among Members pursuant to Section 5.1 until the suspense account is exhausted (subject to this Article 15). No Company
Contributions shall be made as long as any amount remains in the suspense account.
