                        SUMMARY OF DIRECTOR COMPENSATION

     Directors of Littelfuse, Inc. (the "Company") who are not also employees of
the Company are paid an annual fee of $40,000, $1,500 for each of the four
regularly scheduled meetings of the Board of Directors (the "Board") attended
and $1,000 for attendance at any special teleconference Board or committee
meetings, plus reimbursement of reasonable expenses relating to attendance at
meetings. Our lead director is paid an additional $7,500 annually; the chairman
of the Audit Committee is paid an additional $10,000 annually; the chairman of
the Compensation Committee is paid an additional $10,000 annually; the chairman
of the Nominating and Governance Committee is paid an additional $5,000
annually; and the chairman of the Technology 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 our common stock, and such shares and any distributions on
those shares are deposited with a third party trustee for the benefit of the
director until the director ceases to be a director of the Company. All
non-employee directors have elected to be compensated in common stock under the
Non-employee Directors Plan, except for Mr. Noglows.

     On April 27, 2007, the stockholders of the Company approved the Littelfuse,
Inc. Amended and Restated Outside Directors' Equity Plan (the "Outside
Directors' Plan"). The Outside Directors' Equity Plan provides for an annual
grant of stock options and restricted stock units with an estimated value of
$90,000. The stock options and restricted stock units vest ratably over three
years. The stock options have an exercise price equal to the fair market value
of our common stock on the date of grant and have a seven year term. The
restricted stock units entitle the director to receive one share of common stock
per unit upon vesting.
