The Plan should be carefully examined before any decision is made to exercise the Option.

3.             Exercise of Option. Subject to the terms and conditions contained herein, including Section 7 hereof, and in the Plan, the Option may be exercised, in whole or in part, to the extent it has become vested, by written notice to the Company at any time and from time to time after the date of grant.

Any part of the Option that is not vested on the Termination Date shall expire and be forfeited on such date, and any part of the Option that is vested on the Termination Date shall also expire and be forfeited to the extent not exercised on or before ninety (90) days following the Termination Date or such shorter period if such ninety (90)-day period would exceed the original term of the Option; provided, that in the event of the death or disability of the Grantee, any part of the Option that is vested on the date of the Termination Date shall expire and be forfeited to the extent not exercised on or before 180 days following the Termination Date or such shorter period if such 180-day period would exceed the original term of the Option.

(b)           Subject to Section 5(d), all unvested Performance Vesting Options shall terminate in their entirety, without any action on the part of the Company, upon the occurrence of a Sale of the Company.

5.             Vesting of Performance Vesting Options.

Any such adjustment to the Adjusted Target EBITDA will not affect the Adjusted Target EBITDA or the Aggregate Test with respect to any fiscal years (or a portion of any fiscal year) prior to the consummation of such transaction.

Company or any Subsidiary and any employee thereof, (ii) hire any person who was an employee of the Company or any Subsidiary at any time within the one (1) year period before the Grantee’s Termination Date, or (iii) induce or attempt to induce any customer, supplier, licensee, licensor, franchisee or other business relation of the Company or any Subsidiary to cease doing business with the Company or such Subsidiary, or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and the Company or any Subsidiary, except with the prior written consent of the Board, which consent will be given at the sole discretion of the Board.

16.           Non-Disclosure.(5) The Grantee agrees that during and at all times after the Term, the Grantee will keep secret all confidential matters and materials of the Company (including its Subsidiaries and Affiliates), including, without limitation, know-how, trade secrets, real estate plans and practices, individual office results, customer lists, pricing policies, operational methods, any information relating to the Company (including any of its Subsidiaries and Affiliates) products, processes, customers and services and other business and financial affairs of the Company (collectively, “Confidential Information”), to which the Grantee had or may have access and will not disclose such Confidential Information to any Person other than (i) the Company, its respective authorized employees and such other Persons to whom the Grantee has been instructed to make disclosure by the Board, (ii) as appropriate (as determined by the Grantee in good faith) to perform the Grantee’s duties to the Company or its Subsidiaries, or (iii) in compliance with legal process or regulatory requirements. “Confidential Information” will not include any information which is in the public domain during or after the Term to the extent that such information is not in the public domain as a consequence of disclosure by the Grantee in violation of this Option Agreement.

18.           Modification.(7)  The Grantee agrees and acknowledges that the duration and scope of the covenants described in Section 15, 16 or 17 are fair, reasonable and necessary in order to protect the goodwill and other legitimate interests of the Company and its Subsidiaries, that adequate consideration has been received by the Grantee for such obligations, and that these obligations do not prevent the Grantee from earning a livelihood. If, however, for any reason any court of competent jurisdiction determines that any restriction contained in Section 15, 16 or 17 are not reasonable, that consideration is inadequate, such restriction will be interpreted, modified or rewritten to include as much of the duration, scope and geographic area identified in Section 15, 16 or 17 as will render such restrictions valid and enforceable.

19.           Remedies.(8) The Grantee acknowledges that the Company will suffer irreparable harm as a result of a breach of this Option Agreement by the Grantee for which an adequate monetary remedy does not exist and a remedy at law may prove to be inadequate. Accordingly, in the event of any actual or threatened breach by the Grantee of any provision of this Option Agreement, the Company will, in addition to any other remedies permitted by law, be entitled to obtain remedies in equity, including without limitation specific performance, injunctive relief, a temporary restraining order and/or a permanent injunction in any court of competent jurisdiction, to prevent or otherwise restrain any such breach without the necessity of proving damages, posting a bond or other security. Such relief will be in addition to and not in substitution of any other remedies available to the Company. The existence of any claim or cause of action by the Grantee against the Company or any of its Subsidiaries, whether predicated on this Option Agreement or otherwise, will not constitute a defense to the enforcement by the Company of this Option Agreement. The Grantee agrees not to defend on the basis that there is an adequate remedy at law.

20.          Governing Law. The validity, construction, interpretation, administration and effect of the Plan, and of its rules and regulations, and rights relating to the Plan and to this Agreement, shall be governed by the substantive laws, but not the choice of law rules, of the State of Delaware. The parties hereto hereby irrevocably and unconditionally submit to the exclusive jurisdiction of any Federal court sitting in the State of Minnesota over any suit, action or proceeding arising out of or relating to this Agreement. The parties hereby agree that service of any process, summons, notice or document by U.S. registered mail addressed to any such party shall be effective service of process for any action, suit or proceeding brought against a party in any such court. The parties hereto hereby irrevocably and unconditionally waive any objection to the laying of venue of any such suit, action or proceeding brought in any such court and any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. The parties hereto agree that a final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon any party and may be enforced in any other courts to whose jurisdiction any party is or may be subject, by suit upon such judgment.
