                                LITTELFUSE, INC.
                        SUMMARY OF DIRECTOR COMPENSATION

         For 2006, directors who are not employees of Littelfuse, Inc. (the
"Company") are paid an annual director's fee of $40,000, $1,500 for each of the
regularly scheduled Board meetings attended and $1,000 for attendance at any
special teleconference Board or Committee meetings, plus reimbursement of
reasonable expenses relating to attendance at meetings. The Lead Director is
paid an additional $7,500 annually, the Chairman of the Audit Committee is paid
an additional $10,000 annually and the Chairman of the Compensation Committee is
paid an additional $5,000 annually. No fees are paid to directors who are also
full-time employees of the Company.

         Under the Littelfuse Deferred Compensation Plan for Non-employee
Directors (the "Non-employee Directors Plan"), a non-employee director, at his
election, may defer receipt of his director's fees. Such deferred fees are used
to purchase shares of the Company's Common Stock, and such shares and any
distributions thereon are deposited with a third party trustee for the benefit
of the director until the director ceases to be a director of the Company.

         The 1993 Stock Plan for Employees and Directors of Littelfuse, Inc.
(the "Stock Plan") provides for a grant at each annual meeting of the Board of
Directors to each non-employee director of non-qualified stock options to
purchase 5,000 shares of Common Stock at the fair market value on the date of
grant.

         The Non-employee Directors Plan and the Stock Plan and the forms of
awards thereunder are filed as exhibits to this Annual Report on Form 10-K for
the fiscal year ended December 31, 2005 (the "Form 10-K"). These plans and
agreements will be discussed further in the Company's Proxy Statement relating
to the 2006 Annual Meeting of Stockholders, which will be incorporated by
reference into this Form 10-K when filed.
