(b)The Company agrees that, as contemplated in Section 13(b) of the Plan, the Optionee may elect to have the Company reduce the number of Option Shares otherwise issuable by a number of Option Shares having a Fair Market Value (as defined in the Plan) equal to the exercise price of the Option being exercised.

7.SHAREHOLDER APPROVAL. Notwithstanding anything herein to the contrary, the exercisability of the Option is subject to the approval by the shareholders of the Company of an increase in the number of shares of Common Stock of the Company issuable pursuant to the Plan from 1,000,000 to 2,000,000 or such greater number of shares of Common Stock as the Compensation Committee of the Board of Directors of the Company shall determine to submit for shareholder approval (“Shareholder Approval”).
