      THIS NON-QUALIFIED STOCK OPTION AGREEMENT is entered into as of

LITTELFUSE, INC., a Delaware corporation (the "Corporation"), with reference to
the following facts:

      A. Pursuant to Section 4(e) of the 1993 Stock Plan for Employees and
Directors of Littelfuse, Inc. (the "Plan"), all persons who are "Eligible
Directors," as such term is defined under the Plan, on the date of the first
meeting of the Board of Directors of the Corporation following each annual
meeting of the stockholders of the Corporation, are entitled to an automatic
grant of an option to purchase certain shares of the common stock, $.01 par

      B. The Optionee was an "Eligible Director," as such term is defined under
the Plan, as of _________________, the date of the first meeting of the Board of
Directors of the Corporation following the _______ annual meeting of the
stockholders of the Corporation, and, therefore, is entitled to said automatic
grant.

      NOW, THEREFORE, IN CONSIDERATION of the foregoing facts, the Corporation
hereby grants the following options:

            1. Grant of Option. The Corporation hereby grants to the Optionee an
      irrevocable option to purchase up to 5,000 shares of Common Stock of the
      Corporation at the price of $ _____________ per share. The number and kind
      of shares subject to this option and the purchase price per share are
      subject to adjustment as provided in the Plan. This option shall expire on
      the day before the tenth (10th) anniversary of the date hereof unless
      earlier terminated in accordance with the provisions hereof.

            2. Exercise of Option. Subject to the terms of the Plan, this option
      may be exercised as follows: with respect to twenty percent (20%) of the
      Common Stock covered hereby during the nine (9) year period commencing one
      (1) year following the date of grant; with respect to an additional twenty
      percent (20%) of the Common Stock covered hereby during the eight (8) year

      Stock covered hereby during the five (5) year period commencing five (5)
      years following the date of grant. Optionee hereby waives any longer
      exercise period to which Optionee may be entitled pursuant to Section 4(e)
      of the Plan. This option shall be exercised by delivery of written notice
      to the Corporation stating the number of shares with respect to which the
      option is being exercised, together with full payment of the purchase
      price therefor. Payment may be made in cash or in such other form or
      combination of forms permitted by the Plan as shall be acceptable to the
      Committee.

            3. Reserved Shares. The Corporation has duly reserved for issuance a
      number of authorized but unissued shares adequate to fulfill its
      obligations under this Agreement. During the term of this Agreement the
      Corporation shall take such action as may be necessary to maintain at all
      times an adequate number of shares reserved for issuance or treasury
      shares to fulfill its obligations hereunder.

            4. Termination of Service as Director. In the event that the
      Optionee ceases to serve as a director of the Corporation for any reason
      other than as set forth in paragraph 12 of the Plan, this option may,
      subject to the provisions of the Plan, be exercised (but only to the
      extent that the Optionee was entitled to do so at the time of such
      cessation of service as a director) at any time within three (3) months
      after such cessation of service as a director, but in no case later than
      the date on which this option was originally scheduled to expire. Any
      portion of this option which was not exercisable by the Optionee at the
      time of any such cessation of service shall be cancelled and forfeited and
      the Optionee shall not have any further rights whatsoever with respect
      thereto.

            5. Assignment or Transfer. This option may not be assigned or
      transferred except by will, by the laws of descent and distribution, and
      by gift pursuant to the provisions of Section 9c of the Plan, and shall be
      exercisable only by the Optionee during the Optionee's lifetime.

            6. Plan and Committee. The construction of the terms of this
      Agreement shall be controlled by the Plan, a copy of which is attached
      hereto as Exhibit A and hereby made a part hereof as though set forth
      herein verbatim, and the rights of the Optionee are subject to
      modification and termination in certain events as provided in the Plan.
      All words and phrases not otherwise defined herein shall have the meanings
      provided in the Plan. The Committee's interpretations of and
      determinations under any of the provisions of the Plan or this Agreement
      shall be conclusive.

            7. Compliance with Law. This option shall not be exercised and no
      shares shall be issued in respect hereof, unless in compliance with
      applicable federal and state tax and securities laws.

                  7.1. Certificate Legends. The certificates for shares
            purchased pursuant to this option shall bear any legends deemed
            necessary by the Committee.

                  7.2. Representations of the Optionee. As a condition to the
            exercise of this option, the Optionee will deliver to the
            Corporation such signed

            representations as may be necessary, in the opinion of counsel
            satisfactory to the Corporation, for compliance with applicable
            federal and state securities laws.

                  7.3. Resale. The Optionee's ability to transfer shares
            purchased pursuant to this option or securities acquired in lieu
            thereof or in exchange therefor may be restricted under federal or
            state securities laws. The Optionee shall not resell or offer for
            resale such shares or securities unless they have been registered or
            qualified for resale under all applicable federal and state
            securities laws or an exemption from such registration or
            qualification is available in the opinion of counsel satisfactory to
            the Corporation.

            8. Notice. Every notice or other communication relating to this
      Agreement shall be in writing and shall be mailed or delivered to the
      party for whom it is intended at such address as may from time to time be
      designated by such party in a notice mailed or delivered to the other
      party as herein provided; provided, however, that unless and until some
      other address be so designated, all notices or communications by the
      Optionee to the Corporation shall be mailed or delivered to the
      Corporation to the attention of its Secretary at 800 East Northwest
      Highway, Des Plaines, Illinois 60016, and all notices or communications by
      the Corporation to the Optionee may be given to the Optionee personally or
      may be mailed to the Optionee at the most recent address which the
      Optionee has provided in writing to the Corporation.

            9. Tax Treatment. This option is a non-qualified option and shall
      not be treated as an incentive stock option pursuant to Section 422 of the
      Internal Revenue Code of 1986, as amended. The Optionee acknowledges that
      the tax treatment of this option, shares subject to this option or any
      events or transactions with respect thereto may be dependent upon various
      factors or events which are not determined by the Plan or this Agreement.
      The Corporation makes no representations with respect to and hereby
      disclaims all responsibility as to such tax treatment.

            10. Withholding Taxes. The Corporation shall have the right to
      require the Optionee to remit to the Corporation an amount sufficient to
      satisfy any federal, state or local withholding tax requirement prior to
      the delivery of any shares of Common Stock acquired by the exercise of the
      option granted hereunder. In each case of the exercise of the option, the
      Corporation will notify the Optionee of the amount of the withholding tax
      which must be paid under federal and, where applicable, state and local
      law. Upon receipt of such notice, the Optionee shall promptly remit to the
      Corporation the amount specified in such notice. No amounts of income
      received by the Optionee pursuant to this Agreement shall be considered
      compensation for purposes of any pension or retirement plan, insurance
      plan or any other employee benefit plan of the Corporation or any
      Subsidiary.
