Form of Non-Qualified Stock Option Award Agreement

Portion of Shares as to Which

Option Becomes Vested and Exercisable

Non-Qualified Stock Option. This Option is not intended to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code and will be interpreted accordingly.

Vesting and Exercisability of Option.

Expiration. This Option will expire and will no longer be exercisable at 4:00 p.m. Central Time on the earliest of:

The expiration date specified on the cover page of this Agreement;

Upon your termination of Service for Cause;

Upon the expiration of any applicable period specified in Section 6(e) of the Plan or Section 2 of this Agreement during which this Option may be exercised after your termination of Service; or

The date (if any) fixed for termination or cancellation of this Option pursuant to Section 12 of the Plan.

Service Requirement. Except as otherwise provided in Section 6(e) of the Plan or Section 2 of this Agreement, this Option may be exercised only while you continue to provide Service to the Company or any Affiliate, and only if you have continuously provided such Service since the Grant Date of this Option.

Exercise of Option. Subject to Section 4, the vested and exercisable portion of this Option may be exercised in whole or in part at any time during the Option term by delivering a written or electronic notice of exercise to the Company’s Corporate Controller or to such other party as may be designated by such officer including an outside plan administrator, and by providing for payment of the exercise price of the Shares being acquired and any related withholding taxes. The notice of exercise must be in a form approved by the Company and state the number of Shares to be purchased, the method of payment of the aggregate exercise price and the directions for the delivery of the Shares to be acquired, and must be signed or otherwise authenticated by the person exercising the Option. If you are not the person exercising the Option, the person submitting the notice also must submit appropriate proof of his/her right to exercise the Option.

Payment of Exercise Price. When you submit your notice of exercise, you must include payment of the exercise price of the Shares being purchased through one or a combination of the following methods:

Cash (including personal check, cashier’s check or money order);

By means of a broker-assisted cashless exercise in which you irrevocably instruct your broker to deliver proceeds of a sale of all or a portion of the Shares to be issued pursuant to the exercise to the Company in payment of the exercise price of such Shares; or

By delivery to the Company of Shares (by actual delivery or attestation of ownership in a form approved by the Company) already owned by you that are not subject to any security interest and that have an aggregate Fair Market Value on the date of exercise equal to the exercise price of the Shares being purchased; or

By authorizing the Company to retain, from the total number of Shares as to which the Option is being exercised, that number of Shares having a Fair Market Value on the date of exercise equal to the exercise price for the total number of Shares as to which the Option is being exercised.

Withholding Taxes. You may not exercise this Option in whole or in part unless you make arrangements acceptable to the Company for payment of any federal, state, local or foreign withholding taxes that may be due as a result of the exercise of this Option. You hereby authorize the Company (or any Affiliate) to withhold from payroll or other amounts payable to you any sums required to satisfy such withholding tax obligations, and otherwise agree to satisfy such obligations in accordance with the provisions of Section 14 of the Plan. You may satisfy such withholding tax obligations by delivering Shares you already own or by having the Company retain a portion of the Shares being acquired upon exercise of the Option, provided you notify the Company in advance of any exercise of your desire to pay withholding taxes in this manner. Delivery of Shares upon exercise of this Option is subject to the satisfaction of applicable withholding tax obligations.

Delivery of Shares. As soon as practicable after the Company receives the notice of exercise and payment of the exercise price as provided above, and has determined that all other conditions to exercise, including satisfaction of withholding tax obligations and compliance with applicable laws as provided in Section 16(c) of the Plan, have been satisfied, it shall deliver to the person exercising the Option, in the name of such person, the Shares being purchased, as evidenced by issuance of a stock certificate or certificates, electronic delivery of such Shares to a brokerage account designated by such person, or book-entry registration of such Shares with the Company’s transfer agent. The Company shall pay any original issue or transfer taxes with respect to the issue or transfer of the Shares and all fees and expenses incurred by it in connection therewith. All Shares so issued shall be fully paid and nonassessable.

Transfer of Option. During your lifetime, only you (or your guardian or legal representative in the event of legal incapacity) may exercise this Option except in the case of a transfer described below. You may not assign or transfer this Option except (i) for a transfer upon your death in accordance with your will or by the laws of descent and distribution, or (ii) pursuant to a domestic relations order. The Option held by any such transferee will continue to be subject to the same terms and conditions that were applicable to the Option immediately prior to its transfer and may be exercised by such transferee as and to the extent that the Option has become exercisable and has not terminated in accordance with the provisions of the Plan and this Agreement.

No Shareholder Rights Before Exercise. Neither you nor any permitted transferee of this Option will have any of the rights of a shareholder of the Company with respect to any Shares subject to this Option until a certificate evidencing such Shares has been issued, electronic delivery of such Shares has been made to your designated brokerage account, or an appropriate book entry in the Company’s stock register has been made. No adjustments shall be made for dividends or other rights if the applicable record date occurs before your stock certificate has been issued, electronic delivery of your Shares has been made to your designated brokerage account, or an appropriate book entry in the Company’s stock register has been made, except as otherwise described in the Plan.

Governing Plan Document. This Agreement and Option are subject to all the provisions of the Plan, and to all interpretations, rules and regulations which may, from time to time, be adopted and promulgated by the Committee pursuant to the Plan. If there is any conflict between the provisions of this Agreement and the Plan, the provisions of the Plan will govern.

Choice of Law. This Agreement will be interpreted and enforced under the laws of the state of Minnesota (without regard to its conflicts or choice of law principles).

Binding Effect. This Agreement will be binding in all respects on your heirs, representatives, successors and assigns, and on the successors and assigns of the Company.

Electronic Delivery and Acceptance. The Company may deliver any documents related to this Option Award by electronic means and request your acceptance of this Agreement by electronic means. You hereby consent to receive all applicable documentation by electronic delivery and to participate in the Plan through an on-line (and/or voice activated) system established and maintained by the Company or the Company’s third-party stock plan administrator.
