4. Common Stock Available for Awards. Subject to adjustment as provided in Section 14 hereof, the number of shares that may be issued under the Plan for Awards during the term of the Plan is 12,000,000 shares of Common Stock, all of which may be in the form of incentive stock options. Any shares subject to an Award which are used in settlement of tax withholding obligations shall be deemed not to have been issued for purposes of determining the maximum number of shares available for issuance under the Plan. Likewise, if any Stock Option is exercised by tendering shares, either actually or by attestation, to the Company as full or partial payment for such exercise under this Plan, only the number of shares issued net of the shares tendered shall be deemed issued for purposes of determining the maximum number of shares available for issuance under the Plan.

The Company shall take whatever actions are necessary to file required documents with the U.S. Securities and Exchange Commission and any other appropriate governmental authorities and stock exchanges to make shares of Common Stock available for issuance pursuant to Awards.

5. Administration. The Plan shall be administered by the Committee, which shall have full and exclusive power to interpret the Plan, to determine which persons are Plan Participants, to grant waivers of Award restrictions, and to adopt such rules, regulations and guidelines for carrying out the Plan as it may deem necessary or proper, all of which powers shall be executed in the best interests of the Company and in keeping with the objectives of the Plan. All determinations made by the Committee regarding the Plan or an Award shall be binding and conclusive as regards the Company, the Participants, and any other interested persons.

6. Delegation of Authority. Except to the extent prohibited by applicable law or the applicable rules of a stock exchange, the Committee may delegate to the chief executive officer and to other senior officers of the Company its duties under the Plan pursuant to such conditions or limitations as the Committee may establish. Any such delegation may be revoked by the Committee at any time.

7. Awards. The Committee shall determine the type or types of Award(s) to be made to each Participant and shall set forth in the related Award Agreement the terms, conditions and limitations applicable to each Award including any vesting requirements. In all events, upon the occurrence of a Change in Control, all Awards will become fully vested and immediately exercisable. The type of Awards available under the Plan are those listed in this Section 7.

(a) Stock Option. A grant of a right to purchase a specified number of shares of Common Stock the purchase price of which shall be not less than 100% of Fair Market Value on the date of grant, as determined by the Committee. In addition, the Committee may not reduce the purchase price for Common Stock pursuant to a stock option after the date of grant without the consent of the Company’s shareholders, except in accordance with adjustments pursuant to Section 14 hereof. A stock option may be in the form of a nonqualified stock option for all Participants or an incentive stock option (“ISO”) for Participants who are employees. An ISO, in addition to being subject to applicable terms, conditions and limitations established by the Committee, complies with Section 422 of the Code which, among other limitations, provides that the aggregate Fair Market Value (determined at the time the option is granted) of Common Stock for which ISOs are exercisable for the first time by a Participant during any calendar year shall not exceed $100,000; that ISOs shall be priced at not less than 100% of the Fair Market Value on the date of the grant (110% in the case of a Participant who is a 10% shareholder of the Company within the meaning of Section 422 of the Code); and that ISOs shall be exercisable for a period of not more than ten years (five years in the case of a Participant who is a 10% shareholder of the Company).

(b) Restricted Stock Award. An Award of stock for such consideration as the Committee may specify and which may contain transferability or forfeiture provisions including a requirement of future services and such other restrictions and conditions as may be established by the Committee and set forth in the Award Agreement.

8. Deferred Payment of Awards. The Committee may permit selected Participants to elect to defer payments of some or all types of Awards in accordance with procedures established by the Committee which are intended to permit such deferrals to comply with applicable requirements of the Code including, at the choice of Participants, the capability to make further deferrals for payment after retirement. Dividends or dividend equivalent rights may be extended to and made part of any Award denominated in stock or units of stock, subject to such terms, conditions and restrictions as the Committee may establish. The Committee may also establish rules and procedures for the crediting of dividend equivalents for deferred payments denominated in stock or units of stock.

9. Stock Option Exercise. The price at which shares of Common Stock may be purchased under a Stock Option shall be paid in full at the time of the exercise in cash or by means of tendering Common Stock, either directly or by attestation, valued at Fair Market Value on the date of exercise, or any combination thereof.

10. Tax Withholding. The Company shall have the right to deduct applicable taxes from any Award payment and withhold, at the time of delivery or vesting of shares under the Plan, an appropriate number of shares for payment of taxes required by law or to take such other action as may be necessary in the opinion of the Company to satisfy all obligations for withholding of such taxes, but in no event in excess of the minimum withholding required by law. The Company may defer making delivery with respect to Common Stock obtained pursuant to an Award hereunder until arrangements satisfactory to it have been made with respect to any such withholding obligation. If Common Stock is used to satisfy tax withholding, such stock shall be valued based on the Fair Market Value when the tax withholding is required to be made.

11. Amendment or Discontinuance of the Plan. The Board may, at any time, amend or terminate the Plan; provided, however, that

12. Termination of Employment or Service. If the employment of a Participant terminates, other than pursuant to paragraphs (a) through (c) of this Section 12, all unexercised, deferred and unpaid Awards shall terminate 90 days after such termination of employment or service, unless the Award Agreement provides otherwise, and during such 90-day period shall be exercisable only to the extent provided in the Award Agreement. Notwithstanding the foregoing, (i) if a Participant’s employment is terminated for Cause, to the extent the Award is not effectively exercised or has not vested prior to such termination, it shall lapse or be forfeited to the Company immediately upon termination and (ii) a director’s option shall terminate upon the earlier of the tenth anniversary of the date of grant or the third anniversary of the termination of the Participant’s service as a director. In all events, an Award will not be exercisable after the end of its term as set forth in the Award Agreement.

(a) Retirement. When a Participant’s employment terminates as a result of Retirement or early retirement, the Committee (in the form of an Award Agreement or otherwise) may permit Awards to continue in effect beyond the date of Retirement or early retirement, and the exercisability and vesting of any Award may be accelerated.

(b) Resignation in the Best Interests of the Company. When a Participant resigns from the Company and, in the judgment of the chief executive officer or other senior officer designated by the Committee, the acceleration and/or continuation of outstanding Awards would be in the best interests of the Company, the Committee may authorize, where appropriate taking into account any regulatory or accounting implications of such action, the acceleration and/or continuation of all or any part of Awards granted prior to such termination.

(c) Death or Disability of a Participant.

(i) In the event of a Participant’s death, the Participant’s estate or beneficiaries shall have a period specified in the Award Agreement within which to receive or exercise any outstanding Award held by the Participant under such terms, and to the extent, as may be specified in the applicable Award Agreement. Rights to any such outstanding Awards shall pass by will or the laws of descent and distribution in the following order: (a) to beneficiaries so designated by the Participant; if none, then (b) to a legal representative of the Participant; if none, then (c) to the persons entitled thereto as determined by a court of competent jurisdiction.

(ii) In the event a Participant is deemed by the Company to be disabled within the meaning of the Company’s long-term disability plan, the Award shall be exercisable for the period, and to the extent, specified in the Award Agreement. Awards and rights to any such Awards may be paid to or exercised by the Participant, if legally competent, or a legally designated guardian or representative if the Participant is legally incompetent by virtue of such disability.

(iii) After the death or disability of a Participant, the Committee may in its sole discretion at any time (1) terminate restrictions in Award Agreements; (2) accelerate any or all installments and rights; and (3) instruct the Company to pay the total of any accelerated payments in a lump sum to the Participant, the Participant’s estate, beneficiaries or representative, notwithstanding that, in the absence of such termination of restrictions or acceleration of payments, any or all of the payments due under the Awards might ultimately have become payable to other beneficiaries.

(iv) In the event of uncertainty as to interpretation of or controversies concerning this paragraph (c) of Section 12, the Committee’s determinations shall be binding and conclusive.

(d) No Employment or Service Rights. The Plan shall not confer upon any Participant any right with respect to continuation of employment by the Company or service as a director, nor shall it interfere in any way with the right of the Company to terminate any Participant’s employment at any time.

13. Nonassignability. Except as provided in subsection (c) of Section 12 and this Section 13, no Award or any other benefit under the Plan shall be assignable or transferable, or payable to or exercisable by anyone other than the Participant to whom it was granted. Notwithstanding the foregoing, the Committee (in the form of an Award Agreement or otherwise) may permit Awards, other than ISOs, to be transferred to members of the Participant’s immediate family, to trusts for the benefit of the Participant and/or such immediate family members, and to partnerships or other entities in which the Participant and/or such immediate family members own all the equity interests. For purposes of the preceding sentence, “immediate family” shall mean a Participant’s spouse, issue and spouses of his issue.

14. Adjustments. In the event of any change in the outstanding Common Stock of the Company by reason of a stock split, stock dividend, combination or reclassification of shares, recapitalization, merger, or similar event, the Committee may adjust proportionally (a) the number of shares of Common Stock (i) reserved under the Plan, (ii) available for ISOs, (iii) for which Awards may be granted to an individual Participant, and (iv) covered by outstanding Awards denominated in stock, (b) the stock prices related to outstanding Awards; and (c) the appropriate Fair Market Value and other price determinations for such Awards. In the event of any other change affecting the Common Stock or any distribution (other than normal cash dividends) to holders of Common Stock, such adjustments as may be deemed equitable by the Committee, including adjustments to avoid fractional shares, shall be made to give proper effect to such event. In the event of a corporate merger, consolidation, acquisition of property or stock, separation, reorganization or liquidation, the Committee shall be authorized to issue or assume Awards, whether or not in a transaction to which Section 424(a) of the Code applies, by means of substitution of new Awards for previously issued awards or an assumption of previously issued awards.

15. Notice. Any notice to the Company required by any of the provisions of the Plan shall be addressed to the director of human resources or to the chief executive officer of the Company in writing, and shall become effective when it is received by the office of either of them.

16. Unfunded Plan. The Plan shall be unfunded. Although bookkeeping accounts may be established with respect to Participants who are entitled to Common Stock under the Plan, any such accounts shall be used merely as a bookkeeping convenience. The Company shall not be required to segregate any Common Stock, nor shall the Plan be construed as providing for such segregation, nor shall the Company nor the Board nor the Committee be deemed to be a trustee of any Common Stock to be granted under the Plan. Any liability of the Company to any Participant with respect to a grant of Common Stock or rights thereto under the Plan shall be based solely upon any contractual obligations that may be created by the Plan and any Award Agreement; no such obligation of the Company shall be deemed to be secured by any pledge or other encumbrance on any property of the Company. Neither the Company nor the Board nor the Committee shall be required to give any security or bond for the performance of any obligation that may be created by the Plan.

17. Governing Law. The Plan and all determinations made and actions taken pursuant hereto shall be governed by the laws of the State of Wisconsin without giving effect to its conflicts of law provisions.

18. Effective and Termination Dates. The effective date of the Plan is April 22, 2003. The Plan shall terminate on April 21, 2013 subject to earlier termination by the Board pursuant to Section 11, after which no Awards may be made under the Plan, but any such termination shall not affect Awards then outstanding or the authority of the Committee to continue to administer the Plan.

19. Other Benefit and Compensation Programs. Payments and other benefits received by a Participant pursuant to an Award shall not be deemed a part of such Participant’s regular, recurring compensation for purposes of the termination or severance plans of the Company and shall not be included in, nor have any effect on, the determination of benefits under any other employee benefit plan, contract or similar arrangement, unless the Committee expressly determines otherwise.
