                                     FORM OF
                                LITTELFUSE, INC.
                          PERFORMANCE SHARES AGREEMENT
          UNDER THE LITTELFUSE, INC. EQUITY INCENTIVE COMPENSATION PLAN

     THIS PERFORMANCE SHARES AGREEMENT is entered into as of _______ __, 20__,
between _____________________ (the "Recipient") and LITTELFUSE, INC., a Delaware
corporation (the "Corporation"), with reference to the following facts:

     A. Pursuant to the Littelfuse, Inc. Equity Incentive Compensation Plan (the
"Plan"), the Corporation is authorized to grant awards of rights ("Performance
Shares") to acquire shares of its Common Stock, $.01 par value (the "Common
Stock"), on a restricted basis as provided in the Plan to officers and employees
of the Corporation or any Subsidiary as an incentive for future performance.

     B. The Corporation desires to grant Performance Shares to the Recipient.

     NOW, THEREFORE, IN CONSIDERATION of the foregoing facts and other good and
valuable consideration, the parties hereto hereby agree as follows:

          1. Grant of Performance Shares. (a) The Corporation hereby grants to
     the Recipient an award of Performance Shares (the "Award") entitling the
     Recipient to acquire up to _______ shares of the Common Stock (hereinafter
     referred to as the "Maximum Performance Shares Amount"), subject in all
     respects to the provisions of the Plan and the terms and conditions set
     forth herein.

          (b) Plan and Committee. The construction of the terms of this
     Agreement shall be controlled by the Plan, a copy of which has been made
     available to the Recipient, which is hereby made a part hereof as though
     set forth herein verbatim, and the rights of the Recipient 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.

          2. Number of Performance Shares Deemed Earned. (a) The number of
     Performance Shares which the Recipient shall be entitled to be issued or
     paid for in cash pursuant to this Agreement shall be determined pursuant to
     the following formula (the number of Performance Shares resulting from said
     formula shall be referred to as the "Earned Performance Shares Amount"):

               (i) The Recipient shall be deemed to have earned no Performance
          Shares in the event that EBITDA Growth is less than __% or Average
          RONTA is less than __%.

               (ii) The Recipient shall be deemed to have earned __% of the
          Maximum Performance Shares Amount if EBITDA Growth is equal to or
          greater



          than __% but less than __%, and Average RONTA is equal to or greater
          than __% but less than __%. For each full percentage point above the
          EBITDA Growth minimum of __%, the recipient will earn an incremental
          __% of the Maximum Performance Shares Amount, up to a maximum of an
          additional __% of the Maximum Performance Shares Amount. Additionally,
          for each full percentage point above the Average RONTA minimum of __%,
          the recipient will earn an incremental __% of the Maximum Performance
          Shares Amount up to a maximum of an additional __% of the Maximum
          Performance Shares Amount. Therefore, the Maximum Performance Shares
          Amount is earned only when EBITDA Growth is greater than __% and
          Average RONTA is greater than __%. The chart attached hereto as
          Exhibit A illustrates the application of the foregoing formula.

          (b) As used herein, the term "EBITDA" shall mean the consolidated net
     income of the Corporation for each of the 20__, 20__ and 20__ fiscal years
     of the Corporation (hereinafter said three (3) year period is referred to
     as the "Performance Period"); provided, however, that in calculating said
     consolidated net income, no deductions shall be made for any interest,
     taxes, depreciation or amortization.

          (c) As used herein, the term "EBITDA Growth" shall mean the compound
     annual growth rate in EBITDA from fiscal year 20__ through fiscal year 20__
     defined mathematically as follows (but expressed as a percentage):

               EBITDA Growth = (fiscal year 20__ EBITDA / fiscal year 20__
               EBITDA)1/3 - 1

          (d) As used herein, the term "RONTA" shall mean the percentage return
     on net tangible assets for the Corporation for each of the fiscal years of
     the Corporation during the Performance Period, calculated for each such
     fiscal year by dividing the consolidated net income of the Corporation for
     such fiscal year by the average of the amounts of (x) the total assets
     minus the total intangible assets minus the total current liabilities of
     the Corporation at the beginning of such fiscal year and (y) the total
     assets minus the total intangible assets minus the total current
     liabilities of the Corporation at the end of such fiscal year; provided,
     however, that current liabilities shall not include the current portion of
     long term debt for purposes of this calculation.

          (e) As used herein, the term "Average RONTA" shall mean the average
     RONTA for each of the three fiscal years of the Corporation during the
     Performance Period.

          (f) To the extent applicable, all calculations of EBITDA and RONTA,
     and the components thereof, shall be made in accordance with generally
     accepted accounting principles consistently applied.

          (g) In the event that the Corporation shall amend its financial
     statements for any of its fiscal years 20__, 20__ or 20__ at any time after
     _______ __, 20__, and before _________ __, 20__, so that any of the items
     used to calculate EBITDA or RONTA for


                                      -2-



     any of those fiscal years are materially changed, the Committee, in its
     discretion, may make appropriate adjustments to the number of Performance
     Shares deemed earned pursuant to Section 2 hereof.

          (h) In the event that the Corporation or any Subsidiary shall be a
     party to any merger or consolidation or acquisition of assets, shall sell
     all or substantially all of its assets or enter into any other transaction
     which, in the good faith opinion of the Committee, will have a material
     effect (either positive or negative) on EBITDA or RONTA during the
     Performance Period or the ability of the Recipient to obtain the economic
     benefit contemplated by this Agreement, the Committee shall appropriately
     and reasonably adjust the formula contained in Section 2(a) to provide the
     Recipient with substantially the same opportunity to obtain substantially
     the same economic benefit that the Recipient would have if said transaction
     had not been entered into, said adjustment to be evidenced in a writing
     delivered by the Corporation to the Recipient.

          (i) In the event that at anytime from and after the date hereof to and
     including __________ __, 20__, there shall occur any changes in the
     outstanding Common Stock by reason of stock dividends, split-ups,
     recapitalizations, mergers, consolidations, combinations, exchanges of
     shares, separations, reorganizations, liquidations and the like, the
     Committee shall appropriately and reasonably adjust the Maximum Performance
     Shares Amount, the Earned Performance Shares Amount, the number of any
     earned but unissued Performance Shares and/or the amount of any earned but
     unpaid Performance Payments.

          (j) Notwithstanding the foregoing, if the Recipient is a Named
     Executive Officer, the Recipient shall not be entitled to any Performance
     Shares unless and until the Committee has determined and certified that the
     targets set forth in Section 2(a) have been satisfied, in accordance with
     the requirements of Section 162(m) of the Internal Revenue Code of 1986
     (the "Code").

          3. Issuance of Performance Shares. In the event that the Recipient is
     deemed to have earned any Performance Shares pursuant to the provisions of
     Section 2 hereof, a certificate or certificates representing that number of
     shares of the Common Stock which is equal to one-half (1/2) of the Earned
     Performance Shares Amount shall be issued in the Recipient's name on or
     before ________ __, 20__, provided the Recipient has theretofore delivered
     to the Corporation a stock power signed in blank by the Recipient with
     respect to such Performance Shares and in a form which is acceptable to the
     Corporation which may be used by the Corporation to cancel such Performance
     Shares in accordance with the provisions of the Plan and this Agreement.
     Upon issuance of the certificate or certificates for such Performance
     Shares, the Recipient shall be a stockholder with respect to such
     Performance Shares and, subject to the restrictions contained in Section 5
     hereof, shall have all the rights of a stockholder with respect to such
     Performance Shares, including but not limited to, the right to vote such
     Performance Shares and to receive dividends and other distributions paid
     with respect to such Performance Shares. The certificate or certificates
     representing such Performance Shares, together with the executed stock
     power, shall be held in custody by the


                                      -3-



     Corporation or an agent therefor pursuant to the provisions of the Plan for
     the account of the Recipient.

          4. Payment of Cash in Lieu of Issuance of Performance Shares. In the
     event that the Recipient is deemed to have earned any Performance Shares
     pursuant to the provisions of Section 2 hereof, the Corporation shall pay
     to the Recipient on each of _________ __, 20__, 20__ and 20__, an amount in
     cash (in lieu of the issuance of Performance Shares) equal to the product
     of (i) one-sixth (1/6th) of the Earned Performance Shares Amount multiplied
     by (ii) the Fair Market Value of the Common Stock on the payment date, as
     defined in Section 2.14 of the Plan (hereinafter referred to as a
     "Performance Payment").

          5. Restrictions. The Performance Shares awarded pursuant to this
     Agreement and any Performance Shares or Performance Payments which may be
     deemed to be earned or owing with respect thereto shall be subject to the
     following terms and conditions (the "Restrictions"):

               (i) the Recipient shall not be entitled to delivery of a
          certificate representing the Performance Shares until the Restrictions
          pertaining thereto shall be terminated pursuant to either Sections 6

          further obligation on the part of the Corporation in the event that
          the Recipient ceases to be an Employee for any reason prior to
          ________ __, 20__;

               (v) all of the Performance Shares which are issued pursuant to

     Performance Shares or Performance Payment is deemed under Section 409A of
     the Code to be compensation deferred under a nonqualified deferred
     compensation plan, the Recipient is a "specified employee," as such term is
     defined under such Section 409A, and the restrictions on the Performance
     Shares are deemed to have been terminated as a result of a separation from
     service (as such term is used in such Section 409A) then such stock
     certificate shall not be delivered and such payment shall not be made to
     the Recipient until the first business day following the six-month
     anniversary of the date of such separation from service (or, if earlier,
     the date of death of the Recipient).

          10. Compliance with Law. No Performance Shares shall be issued
     pursuant to this Agreement unless said issuance is in compliance with
     applicable federal and state tax and securities laws.

          10.1. Certificate Legends. The certificates for Performance Shares
     issued pursuant to this Agreement shall bear any legends deemed necessary
     or appropriate by the Corporation.

          10.3. Resale. In addition to the restrictions contained in the Plan,
     the Recipient's ability to transfer Performance Shares issued pursuant to
     this Agreement or securities acquired in lieu thereof or in exchange
     therefor may be restricted under federal or state securities laws. The
     Recipient shall not resell or offer for resale such Performance 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.

          11. 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


                                       -6-



     some other address be so designated, all notices or communications by the
     Recipient to the Corporation shall be mailed or delivered to the

     or may be mailed to the Recipient at the most recent address which the
     Recipient has provided in writing to the Corporation.

          12. Tax Treatment. The Recipient acknowledges that the tax treatment
     respecting the Performance Shares issued and Performance Payments made
     pursuant to this Agreement 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 to the Recipient with respect to and hereby disclaims all
     responsibility as to such tax treatment.

          13. Withholding Taxes. The Corporation shall have the right to deduct
     from the amount of any Performance Payment an amount sufficient to satisfy
     any federal, state or local withholding tax requirement. The Corporation
     shall have the right to require the Recipient to remit to the Corporation
     an amount sufficient to satisfy any federal, state or local withholding tax
     requirement prior to the issuance or delivery of any Performance Shares to
     the Recipient. The Corporation will notify the Recipient 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 Recipient shall
     promptly remit to the Corporation the amount specified in such notice. No
     amounts of income received by the Recipient 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.

          14. Effect on SERP. The Corporation and the Recipient agree that
     neither the value of any shares of Common Stock issued, nor the amount of
     any cash paid, to the Recipient pursuant to this Agreement shall be
     included in the definition of "Compensation" under the Littelfuse, Inc.
     Supplemental Executive Retirement Plan.

     IN WITNESS WHEREOF, the Corporation and the Recipient have executed this
Performance Shares Agreement effective as of the date first set forth above.
