ITEM 5.02 DEPARTURE OF DIRECTORS OR CERTAIN OFFICERS; ELECTION OF DIRECTORS;
          APPOINTMENT OF CERTAIN OFFICERS; COMPENSATORY ARRANGEMENTS OF CERTAIN
          OFFICERS.

      On April 25, 2008, at the Annual Meeting of Stockholders of Littelfuse,
Inc. (the "Company"), the stockholders approved the Littelfuse, Inc. 2008 Annual
Incentive Plan (the "Annual Incentive Plan"). The Annual Incentive Plan is
administered by the Compensation Committee (the "Committee") of the Board of
Directors (the "Board") of the Company.

      The Annual Incentive Plan provides for grants of cash incentive awards, in
the discretion of the Committee, to the principal executive officer, the
principal financial officer and each of the other three most highly compensated
executive officers of the Company (the "Named Executive Officers") and key
employees of the Company. Awards are based on the achievement of performance
factors specified in the award during a designated performance period, generally
a twelve-month period. Each award specifies a threshold, target and maximum
award a participant in the plan is to receive based on the level at which the
participant's performance factors are achieved. Awards may be stated either as a
dollar amount or a percentage of the participant's base salary (as in effect
when the award is determined).

      In the case of a Named Executive Officer, the performance factors must be
objective and based solely upon one or more business criteria, including, but
not limited to, sales, margins, volume, cash flow, earnings per share, stock
price, net income, cash from operations, market share, and return on assets,
which may apply to the Named Executive Officer in question, an identifiable
business unit or the Company as a whole, and on an annual or other periodic or
cumulative basis. The performance factors for other participants may include
such business criteria as the Committee may determine to be appropriate, which
may include financial and nonfinancial performance goals that are linked to the
individual's business unit, to the individual's areas of responsibility, or to
the Company as a whole.

      The Committee must designate the participants eligible to receive awards
during the first 90 days of each performance period. The Committee retains the
authority to decrease the award of a Named Executive Officer, and to increase or
decrease the award of any other participant, in its sole discretion. No award
payable to any participant for a performance period may exceed $2,000,000. In
general, a participant must be employed on the last day of a performance period
to receive payment of any award earned for such performance period. The Annual
Incentive Plan may be amended to the extent allowable by rules and regulations
applicable to the Company, and the Annual Incentive Plan will terminate on April
25, 2013. The text of the Annual Incentive Plan is incorporated herein by
reference from Exhibit A to the Company's Proxy Statement for Annual Meeting of
Stockholders held on April 25, 2008, as filed with the Securities and Exchange
Commission on March 26, 2008 (the "2008 Proxy Statement").
