Reload Options. The Committee may, in its discretion, provide in the terms of any Option Grant Certificate that if the Participant delivers shares of Stock already owned or to be received upon exercise of the Option in full or partial payment of the option price, or in full or partial payment of the tax withholding obligations incurred on account of the exercise of the Option, the Optionee shall automatically and immediately upon such exercise be granted an additional option (a “Reload Option”) to purchase the number of shares of Stock delivered by the Optionee to the Company, on such terms and conditions as the Committee may determine under the terms of the Plan. Notwithstanding the preceding, the purchase price of shares of Stock acquired under a Reload Option shall be not less than the Fair Market Value of a share of Stock on the date the Reload Option is issued.

The Parties executed the following letter agreements (the “Reload Offer Letters”):

No Repricing of Options. The Committee may not without the approval of the stockholders of the Company lower the exercise price of an outstanding Option, whether by amending the exercise price of the outstanding Option or through cancellation of the outstanding Option and issuance of a replacement or substitute Option; provided that stockholder approval shall not be required for adjustments made in connection with an event described in Section 8 in order to prevent enlargement, dilution or diminishment of rights.

Options. Subject to the terms of this Plan, the Administrator will determine all terms and conditions of each Option, including but not limited to: # whether the Option is an “incentive stock option” which meets the requirements of Code Section 422, or a “nonqualified stock option” which does not meet the requirements of Code Section 422; # the grant date, which may not be any day prior to the date that the Administrator approves the grant; # the number of Shares subject to the Option; # the exercise price, which may not be less than the Fair Market Value of the Shares subject to the Option as determined on the date of grant; # the terms and conditions of vesting and exercise; and # the term, except that an Option must terminate no later than ten (10) years after the date of grant. In all other respects, the terms of any incentive stock option should comply with the provisions of Code Section 422 except to the extent the Administrator determines otherwise. Except to the extent Administrator determines otherwise, a Participant may exercise an Option in whole or part after the right to exercise the Option has accrued, provided that any partial exercise must be for one hundred (100) Shares or multiples thereof. If an Option that is intended to be an incentive stock option fails to meet the requirements thereof, the Option shall automatically be treated as a nonqualified stock option to the extent of such failure.

Options. We will recommend to the Board of Directors of the Company that you be granted the opportunity to purchase up to seven hundred and fifty thousand (750,000) shares of Common Stock of the Company (the “Option”) under our 2006 Stock Plan (the “Plan”) at the fair market value of the Company’s Common Stock, as determined by the Board of Directors on the date the Board approves such grant. The shares you will be given the opportunity to purchase will vest at the rate of 25% percent at the end of your first anniversary with the Company, and an additional 2.08333% percent per month thereafter, so long as you remain continuously employed by the Company. However, the grant of such options by the Company is subject to the Board’s approval and this promise to recommend such approval is not a promise of compensation and is not intended to create any obligation on the part of the Company. Further details on the Plan and any specific option grant to you will be provided upon approval of such grant by the Company’s Board of Directors.

Options. The Committee is authorized to grant Options to any Eligible Person on the following terms and conditions:

“Stock Option” means the right of a Participant to purchase Stock pursuant to an Incentive Stock Option, a Non-Qualified Option or a Reload Option awarded pursuant to the provisions of the Plan.
