Shares of AMPS held in "street name," however, may be voted under certain conditions by broker-dealer firms with respect to Item 3 and counted for purposes of establishing a quorum if no instructions are received one business day before the Meeting, or, if adjourned, one business day before the day to which the Meeting is adjourned.
