On each day during the Order Period in which the Nasdaq Market (the “Market”) is open and the Stock trades regular way in the Market, Broker can execute trades in an aggregate quantity not to exceed the daily share limit prescribed by 10b-18. In addition, Broker can execute one block trade per week in a quantity greater than the minimum prescribed under 10b-18 and less than or equal to 10,000 shares. Issuer agrees to pay a commission of 10 cents per share and shall pay no more than the following prices, before commissions.

It is the intent of the parties that this Plan comply with the requirements of Rule 10b5-1(c)(1)(i)(B) under the Exchange Act and this Plan shall be interpreted to comply with the requirements of Rule 10b5-1(c). Furthermore, this Plan has been approved as a 10b5-1 trading plan by Issuer’s Chief Compliance Officer or outside legal counsel.

Issuer may modify or terminate this Plan at any time by giving written notice to Broker.

Sincerely,
