Any Shares of a Participant that are sold by the Company, or by a broker engaged by the Company (the "Broker"), to fund Withholding Obligations will be sold as soon as practicable in transactions effected on the exchange on which the Shares of the Company are then listed for trading. In effecting the sale of any such Shares, the Company or the Broker will exercise its sole judgment as to the timing and manner of sale and will not be obligated to seek or obtain a minimum price. Neither the Company nor the Broker will be liable for any loss arising out of any sale of such Shares including any loss relating to the manner or timing of such sales, the prices at which the Shares are sold or otherwise. In addition, neither the Company nor the Broker will be liable for any loss arising from a delay in transferring any shares to a Participant.
