Except as otherwise provided herein, as soon as practicable following the Committee’s determination pursuant to Section 6.1 for the applicable Performance Period, each Participant shall receive a cash lump sum payment of his or her Award, less required withholding. In no event shall such payment be made later than March 15 following the end of the Performance Period.

Notwithstanding the foregoing, if a Participant’s employment is terminated for Cause, the Participant shall in all cases forfeit any Award not already paid.

8.    General Provisions.

8.1.    Compliance with Legal Requirements. The Plan and the granting of Awards shall be subject to all applicable federal and state laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may be required.

8.2.    Non-transferability. A person’s rights and interests under the Plan, including any Award previously made to such person or any amounts payable under the Plan may not be assigned, pledged, or transferred.

8.3.    No Right to Employment. Nothing in the Plan or in any notice of Award shall confer upon any person the right to continue in the employment of the Company or any Affiliate or affect the right of the Company or any Affiliate to terminate the employment of any Participant.

8.4.    No Right to Award. Unless otherwise expressly set forth in an employment agreement signed by the Company and a Participant, a Participant shall not have any right to any Award under the Plan until such Award has been paid to such Participant and participation in the Plan in one Performance Period does not connote any right to become a Participant in the Plan in any future Performance Period.

8.5.    Withholding. The Company shall have the right to withhold from any Award, any federal, state or local income and/or payroll taxes required by law to be withheld and to take such other action as the Committee may deem advisable to enable the Company and Participants to satisfy obligations for the payment of withholding taxes and other tax obligations relating to an Award.

8.6.    Amendment or Termination of the Plan. The Board or the Committee may, at any time, amend, suspend or terminate the Plan in whole or in part. Notwithstanding the foregoing, no amendment shall adversely affect the rights of any Participant to Awards allocated prior to such amendment, suspension or termination.

8.7.    Unfunded Status. Nothing contained in the Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind or a fiduciary relationship between the Company and any Participant, beneficiary or legal representative or any other person. To the extent that a person acquires a right to receive payments under the Plan, such right shall be no greater than the right of an unsecured general creditor of the Company. All payments to be made hereunder shall be paid from the general funds of the Company and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in the Plan. The Plan is not intended to be subject to the Employee Retirement Income Security Act of 1974, as amended (ERISA).

8.8.    Governing Law. The Plan shall be construed, administered and enforced in accordance with the laws of Wisconsin without regard to conflicts of law.

8.9.    Section 409A of the Code. It is intended that payments under the Plan qualify as short-term deferrals exempt from the requirements of Section 409A of the Code. In the event that any Award does not qualify for treatment as an exempt short-term deferral, it is intended that such amount will be paid in a manner that satisfies the requirements of Section 409A of the Code. The Plan shall be interpreted and construed accordingly.

8.10.    Expenses. All costs and expenses in connection with the administration of the Plan shall be paid by the Company.

8.11.    Section Headings. The headings of the Plan have been inserted for convenience of reference only and in the event of any conflict, the text of the Plan, rather than such headings, shall control.

8.12.    Severability. In the event that any provision of the Plan shall be considered illegal or invalid for any reason, such illegality or invalidity shall not affect the remaining provisions of the Plan, but shall be fully severable, and the Plan shall be construed and enforced as if such illegal or invalid provision had never been contained therein.

8.13.    Gender and Number. Except where otherwise indicated by the context, wherever used, the masculine pronoun includes the feminine pronoun; the plural shall include the singular, and the singular shall include the plural.

8.14.    Non-Exclusive. Nothing in the Plan shall limit the authority of the Company, the Board or the Committee to adopt such other compensation arrangements, as it may deem desirable for any Participant.

8.15.    Notice. Any notice to be given to the Company or the Committee pursuant to the provisions of the Plan shall be in writing and directed to the Chief Human Resources Officer of the Company at 401 Charmany Drive, Madison, WI 53719.

8.16.    Successors. All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding upon any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation or otherwise, of all or substantially all of the assets of the Company.

8.17.    Clawback. Any Award received under the Plan shall be subject to potential cancellation, recoupment, rescission, payback or other similar action in accordance with any applicable Company clawback policy (the “Policy”) or any applicable law. Notwithstanding the foregoing, until such time as the Company adopts the Policy, in the event of a material restatement of the Company’s financial results, other than a restatement due to changes in accounting principles or applicable law or interpretations thereof, the Board will review the facts and circumstances that led to the requirement for the restatement and will take such actions, including clawback of any Award, as it deems necessary or appropriate. The Board will consider whether an “executive officer” (as designated from time to time by the Board) received a payment with respect to any Award based on the original financial statements because it appeared he or she achieved Performance Goals which in fact were not achieved based on the restatement. The Board will consider the accountability of any executive officer whose acts or omissions were responsible in whole or in part for the events that led to the restatement and whether such acts or omissions constituted misconduct.

8.18.    Governing Law. The Plan, all Awards, and all actions taken in connection herewith and therewith shall be governed by and construed in accordance with the laws of the State of Wisconsin without reference to principles of conflict of laws, except as superseded by applicable federal law; and any court action commenced to enforce this Agreement shall have as its sole and exclusive venue the County of Dane, Wisconsin.

8.19.    Waiver of Jury Trial.  EXCEPT TO THE EXTENT PROHIBITED BY STATE LAW, AS A CONDITION TO THE GRANTING OR PAYMENT OF AN AWARD PURSUANT TO THIS PLAN, EACH PARTICIPANT AND THE COMPANY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL ACTION, PROCEEDING, CAUSE OF ACTION OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS PLAN, INCLUDING ANY EXHIBITS, SCHEDULES, AND APPENDICES ATTACHED TO THIS PLAN. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF THE OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) IT HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) IT MAKES THIS WAIVER KNOWINGLY AND VOLUNTARILY, AND (D) IT HAS DECIDED TO ENTER INTO THIS PLAN IN CONSIDERATION OF, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.
