4. ADMINISTRATION.

4.1 Committee Authority. This Plan will be administered by the Committee or by the Board acting as the Committee. Subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have full power to implement and carry out this Plan. The Committee will have the authority to:

(a) construe and interpret this Plan, any Award Agreement and any other agreement or document executed pursuant to this Plan;

1

(b) prescribe, amend and rescind rules and regulations relating to this Plan or any Award;

(c) select persons to receive Awards;

(d) determine the form and terms of Awards;

(e) determine the number of Shares or other consideration subject to Awards;

(f) determine whether Awards will be granted singly, in combination with, in tandem with, in replacement of, or as alternatives to, other Awards under this Plan or any other incentive or compensation plan of the Company or any Parent or Subsidiary of the Company;

(g) grant waivers of Plan or Award conditions;

(h) determine the vesting, exercisability and payment of Awards;

(i) correct any defect, supply any omission or reconcile any inconsistency in this Plan, any Award or any Award Agreement;

(j) determine whether an award has been earned; and

(k) make all other determinations necessary or advisable for the administration of this Plan.

4.2 Committee Discretion. Any determination made by the Committee with respect to any Award will be made in its sole discretion at the time of grant of the Award or, unless in contravention of any express term of this Plan or the Award, at any later time, and such determination will be final and binding on the Company and on all persons having an interest in any Award under this Plan. The Committee may delegate to one (1) or more officers or directors of the Company the authority to grant an Award under this Plan to Participants who are not Insiders of the Company. Notwithstanding any provision of the Plan to the contrary, administration of the Plan shall at all times be limited by the requirement that any administrative action or exercise of discretion shall be void (or suitably modified when possible) if necessary to avoid the application to any Participant of taxation under Section 409A of the Code.

5. OPTIONS. The Committee may grant Options to eligible persons and will determine whether such Options will be Incentive Stock Options within the meaning of the Code (“ISOs”) or Nonqualified Stock Options (“NQSOs”), the number of Shares subject to the Option, the Exercise Price of the Option, the period during which the Option may be exercised, and all other terms and conditions of the Option, subject to the following:

5.1 Form of Option Grant. Each Option granted under this Plan will be evidenced by an Option Agreement or other evidence of grant which will expressly identify the Option as an ISO or an NQSO (“Stock Option Agreement”), and will be in such form and contain such provisions (which need not be the same for each Participant) as the Committee may from time to time approve, and which will comply with and be subject to the terms and conditions of this Plan.

5.2 Date of Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant such Option, unless otherwise specified by the Committee. The Stock Option Agreement and a copy of this Plan will be delivered or otherwise made available to the Participant within a reasonable time after the granting of the Option. The Stock Option Agreement, Plan and other documents may be delivered in any manner (including electronic distribution or posting) that meets applicable legal requirements.

5.3 Exercise Period. Options may be exercisable within the times or upon the conditions or events determined by the Committee as set forth in the Stock Option Agreement governing such Option (including, without limitation, upon the attainment during a Performance Period of performance goals based on Performance Factors); provided, however, that no Option will be exercisable after the expiration of ten (10) years from the date the Option is granted. The Committee also may provide for Options to become exercisable at one time or from time to time, periodically or otherwise, in such number of Shares or percentage of Shares as the Committee determines.

2

5.4 Exercise Price. The Exercise Price of an Option will be determined by the Committee when the Option is granted; provided that: (i) the Exercise Price of an ISO will be not less than 100% of the Fair Market Value of the Shares on the date of grant; (ii) the Exercise Price of any ISO granted to a Ten Percent Shareholder will not be less than 110% of the Fair Market Value of the Shares on the date of grant; and (iii) the Exercise Price of an NQSO will not be less than 100% of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased may be made in accordance with Section 12.

5.5 Method of Exercise. Options may be exercised only by delivery to the Company of a stock option exercise notice or agreement (the “Exercise Agreement”) in a form approved by the Committee (which need not be the same for each Participant), stating the number of Shares being purchased, the restrictions imposed on the Shares purchased under such Exercise Agreement, if any, and such representations and agreements regarding the Participant’s investment intent and access to information and other matters, if any, as may be required by or desirable to the Company to comply with applicable securities laws, together with payment in full of the Exercise Price for the number of Shares being purchased. The Exercise Agreement may be delivered in any manner (including electronic distribution or posting) that meets applicable legal requirements.

5.6 Termination. Notwithstanding the exercise periods set forth in the Stock Option Agreement, the exercise of an Option will always be subject to the following:

(a) If the Participant is Terminated for any reason except the Participant’s death or Disability, then the Participant may exercise such Participant’s Options only to the extent that such Options would have been exercisable by the Participant on the Termination Date no later than three (3) months after the Termination Date (or such shorter time period not less than thirty (30) days or longer time period not exceeding five (5) years as may be determined by the Committee, with any exercise beyond three (3) months after the Termination Date deemed to be an NQSO), but in any event no later than the expiration date of the Options.

(b) If the Participant is Terminated because of Participant’s death (or the Participant dies within three (3) months after a Termination other than for Cause or because of the Participant’s Disability), then the Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the Termination Date and must be exercised by the Participant’s legal representative or authorized assignee no later than twelve (12) months after the Termination Date (or such shorter time period not less than six (6) months or longer time period not exceeding five (5) years as may be determined by the Committee, with any exercise beyond (a) three (3) months after the Termination Date when the Termination is for any reason other than the Participant’s death, or (b) twelve (12) months after the Termination Date when the Termination is for the Participant’s death, deemed to be an NQSO), but in any event no later than the expiration date of the Options.

(c) If the Participant is Terminated because of Participant’s Disability, then the Participant’s Options may be exercised only to the extent that such Options would have been exercisable by the Participant on the Termination Date and must be exercised by the Participant (or the Participant’s legal representative or authorized assignee) no later than twelve (12) months after the Termination Date, with any exercise beyond (a) three (3) months after the Termination Date when the Termination is for any reason other than the Participant’s Disability, or (b) twelve (12) months after the Termination Date when the Termination is for the Participant’s Disability, deemed to be an NQSO), but in any event no later than the expiration date of the Options.

(d) If the Participant is terminated for Cause (as determined by the Committee or the Company, in its sole discretion), then Participant’s Options shall expire on such Participant’s Termination Date, or at such later time and on such conditions as are determined by the Committee.

5.7 Limitations on Exercise. The Committee may specify a reasonable minimum number of Shares that may be purchased on any exercise of an Option, provided that such minimum number will not prevent any Participant from exercising the Option for the full number of Shares for which it is then exercisable.

5.8 Limitations on ISOs. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to which ISOs are exercisable for the first time by a Participant during any calendar year (under this Plan or under any other incentive stock option plan of the Company or any Parent or

3

Subsidiary of the Company) will not exceed $100,000. If the Fair Market Value of Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds $100,000, then the Options for the first $100,000 worth of Shares to become exercisable in such calendar year will be ISOs and the Options for the amount in excess of $100,000 that become exercisable in such calendar year will be NQSOs. In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit will be automatically incorporated herein and will apply to any Options granted after the effective date of such amendment.

5.9 Modification, Extension or Renewal. Subject to Section 18, the Committee may modify, extend or renew outstanding Options, or authorize the grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant’s rights under any Option previously granted. Any outstanding ISO that is modified, extended, renewed or otherwise altered will be treated in accordance with Section 424(h) of the Code. Subject to Section 18 of this Plan, by written notice to affected Participants the Committee may reduce the Exercise Price of outstanding Options without the consent of such Participants; provided, however, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 5.4 for Options granted on the date the action is taken to reduce the Exercise Price.

5.10 No Disqualification. Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent of the Participant affected, to disqualify any ISO under Section 422 of the Code.

Administration

The Compensation Committee, the members of which are appointed by the Board of Directors, administers the Purchase Plan. The Compensation Committee currently consists of Mr. Louis A. Simpson, Ms. Michelle Guthrie, and Mr. Edward A. Mueller, all of whom have no material relationships with the Company, its employees or its affiliates.

The Compensation Committee has the authority to construe and interpret any of the provisions of the Purchase Plan.

5.6 Termination. Notwithstanding the exercise periods set forth in the Stock Option Agreement, the exercise of an Option will always be subject to the following:

(a) If the Participant is Terminated for any reason except the Participant’s death or Disability, then the Participant may exercise such Participant’s Options only to the extent that such Options would have been exercisable by the Participant on the Termination Date no later than three (3) months after the Termination Date (or such shorter time period not less than thirty (30) days or longer time period not exceeding five (5) years as may be determined by the Committee, with any exercise beyond three (3) months after the Termination Date deemed to be an NQSO), but in any event no later than the expiration date of the Options.

5.10 No Disqualification. Notwithstanding any other provision in this Plan, no term of this Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent of the Participant affected, to disqualify any ISO under Section 422 of the Code.
