Article 5. Eligibility and Participation 5.1 Eligibility. Persons eligible to participate in this Plan include all Employees of the Company, including Employees who are members of the Board. 5.2 Actual Participation. Subject to the provisions of the Plan, the Committee may, from time to time, select from all eligible Employees, those to whom Awards shall be granted and shall determine the nature and amount of each Award. Article 6. Stock Options 6.1 Grant of Options. Subject to the terms and provisions of the Plan, Options may be granted to Participants in such number, and upon such terms, and at any time and from time to time as shall be determined by the Committee. 6.2 Award Agreement. Each Option grant shall be evidenced by an Award Agreement that shall specific the Option Price, the duration of the Option, the number of Shares to which the Option pertains, and such other provisions as the Committee shall determine. The Award Agreement also shall specify whether the Option is intended to be an ISO within the meaning of Code Section 422, or an NQSO whose grant is intended not to fall under the provisions of Code Section 422. 6.3 Option Price. The Option Price for each grant of an Option under this Plan shall be at least equal to one hundred percent (100%) of the Fair Market Value of a Share on the date the Option is granted or a higher amount. No repricing of Options by any method shall be allowed, including, without limitation, cancellation and reissuance. 6.4 Duration of Options.

Options granted under this Article 6 shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall in each instance approve, which need not be the same for each grant or for each Participant. 6.6 Payment. Options granted under this Article 6 shall be exercised by the delivery of a written notice of exercise to the Company, setting forth the number of Shares with respect to which the Option is to be exercised, accompanied by full payment for the Shares. The Option Price upon exercise of any Option shall be payable to the Company in full either (a) in cash or its equivalent; (b) if permitted in the governing Award Agreement, by tendering previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the total Option Price (provided that the Shares which are tendered must have been held by the Participant for at least six (6) months prior to their tender to satisfy the Option Price); or (c) if permitted in the governing Award Agreement, by a combination of (a) and (b). In addition, if permitted in the Award Agreement, the Participant may also be permitted to exercise Options pursuant to a "cashless exercise" procedure as permitted under the Federal Reserve Board's Regulation T, subject to securities law restrictions. In the event the Participant exercises pursuant to a "cashless exercise" procedure, any net gain on the "cashless exercise," after appropriate tax withholdings, shall be distributed to the Participant in the form of Shares. As soon as practicable after receipt of a written notification of exercise and full payment, the Company shall deliver to the Participant, in the Participant's name, Share certificates in an appropriate amount based upon the number of Shares purchased under the Option(s). If either the purchase price or the Shares of Common Stock upon exercise of any Option or the tax withholding requirement is satisfied by tendering or withholding of Shares of Common Stock, only the number of Shares of Common Stock to be issued net of the Shares of Common Stock tendered or withheld shall be delivered. 6.7 Restrictions on Share Transferability. The Committee may impose such restrictions on any Shares acquired pursuant to the exercise of an Option granted under this Article 6 as it may deem advisable, including, without limitation, restrictions under applicable Federal securities laws, under the requirements of any stock exchange or market upon which such Shares are then listed and/or traded, and under any blue sky or state securities laws applicable to such Shares. 6.8 Termination of Employment. Each Participant's Option Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant's employment with the Company. Such provisions shall be determined in the sole discretion of the Committee, shall be included in the Award Agreement entered into with each Participant, need not be uniform among all Options issued pursuant to this Article 6, and may reflect distinctions based on the reasons for termination of employment. 6.9 Nontransferability of Options. (a) Incentive Stock Options. No ISO granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, all ISOs granted to a Participant under the Plan shall be exercisable during his or her lifetime only by such Participant. (b) Nonqualified Stock Options. Except as otherwise provided in a Participant's Award Agreement, no NQSO granted under this Article 6 may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution. Further, except as otherwise provided in a Participant's Award Agreement, all NQSOs granted to a Participant under this Article 6 shall be exercisable during his or her lifetime only by such Participant. Article 7. Beneficiary Designation Each Participant under the Plan may, from time to time, name any beneficiary or beneficiaries (who may be named contingently or successively) to whom any benefit under the Plan is to be paid in case of his or her death before he or she received any or all of such benefit. Each such designation shall revoke all prior designations by the same Participant, shall be in a form prescribed by the Company, and will be effective only when filed by the Participant in writing with the Company during the Participant's lifetime. In the absence of any such designation, benefits remaining unpaid at the Participant's death shall be paid to the Participant's estate. Article 8. Deferrals The Committee may permit or require a Participant to defer such Participant's receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant by virtue of the exercise of an Option. If any such deferral election is required or permitted, the Committee shall, in its sole discretion, establish rules and procedures for such payment deferrals. Article 9. Rights of Employees 9.1 Employment. Nothing in the Plan shall interfere with or limit in any way the right of the Company to terminate any Participant's employment at any time, nor confer upon any Participant any right to continue in the employ of the Company. 9.2 Participation. No Employee shall have the right to be selected to receive an Award under this Plan, or, having been so selected, to be selected to receive a future Award. Article 10. Change in Control 10.1 Treatment of Outstanding Awards.

Notwithstanding any other provision of this Plan or any Award Agreement provision, the provisions of this Article 10 may not be terminated, amended, or modified on or after the date of a Change in Control to affect adversely any Award theretofore granted under the Plan without the prior written consent of the Participant with respect to said Participant's outstanding Awards. Article 11. Amendment, Modification, and Termination 11.1 Amendment, Modification, and Termination. Subject to Section 10.2 herein, the Board may at any time and from time to time, alter, amend, suspend or terminate the Plan in whole or in part; provided, however, that no amendment which requires shareholder approval in order for the Plan to continue to comply with Rule 16b-3 under the Exchange Act, including any successor to such Rule, shall be effective unless such amendment shall be approved by the requisite vote of shareholders of the Company entitled to vote thereon. The Committee shall not have the authority to cancel outstanding Awards and issue substitute Awards in replacement thereof. 11.2 Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. The Committee may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation the events described in Section 4.3 hereof) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan. 11.3 Awards Previously Granted. No termination, amendment, or modification of the Plan shall adversely affect in any material way any Award previously granted under the Plan, without the written consent of the Participant holding such Award.

With respect to withholding required upon the exercise of Options, Participants may elect, subject to the approval of the Committee, to satisfy the withholding requirement, in whole or in part, by having the Company withhold Shares having a Fair Market Value on the date the tax is to be determined equal to the minimum statutory total tax which could be withheld on the transaction. All such elections shall be irrevocable, made in writing, signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate. Article 13. Indemnification Each person who is or shall have been a member of the Committee, or of the Board, shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under the Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company's approval, or paid by him or her in satisfaction of any judgment in any such action, suit, or proceeding against him or her provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his or her own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such persons may be entitled under the Company's Articles of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless. Article 14. Successors All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, of all or substantially all of the business and/or assets of the Company, or a merger, consolidation, or otherwise.

The granting of Awards and the issuance of Shares under the Plan shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required. 15.4 Securities Law Compliance. With respect to Insiders, transactions under this Plan are intended to comply with all applicable conditions of Rule 16b-3 or its successors under the Exchange Act. To the extent any provision of the plan or action by the Committee fails to so comply, it shall be deemed null and void, to the extent permitted by law and deemed advisable by the Committee. 15.5 Governing Law. To the extent not preempted by Federal law, the Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the state of South Dakota. 15.6 Unfunded Status of the Plan.
