(1) On December 13, 2010, The Douglas S. Schatz and Jill E. Schatz Family Trust settled a variable prepaid forward contract that was entered into on May 8, 2009 with a securities broker. The contract obligated the Family Trust to deliver to the securities broker up to 150,000 shares of AEIS common stock (or, at the Family Trust's election, an equivalent amount in cash) on the maturity date of the contract, which was December 13, 2010. In exchange for assuming this obligation, the Family Trust received a cash payment of $1,114,487.04 upon execution of the contract. The Family Trust had pledged 150,000 shares of AEIS common stock to secure its obligations under the contract, but retained dividend and voting righs in such shares during the term of the pledge.
(2) The contract provided that the number of shares of AEIS common stock that the Family Trust would be obligated to deliver to the securities broker on the maturity date would be determined based on the closing price of AEIS common stock on the maturity date. As of the maturity date, such closing price was $12.8118 and the Family Trust transferred 122,978 shares of AEIS common stock to the securities broker. The remaining shares were released from the pledge account with the securities broker but immediately were pledged to Silicon Valley Bank as collateral for a line of credit entered into by the Family Trust, Douglas S. Schatz and Jill E. Schatz.
(3) Douglas S. Schatz and Jill E. Schatz, husband and wife, are co-trustees of the Family Trust and may be deemed to be indirect beneficial owners of the shares of AEIS common stock held directly by the Family Trust. Douglas S. Schatz is a director of AEIS.
(4) All shares of AEIS common stock reported on this Form 4 are held directly by the Family Trust and are pledged to Silicon Valley Bank as collateral for a line of credit entered into by the Family Trust, Douglas S. Schatz and Jill E. Schatz.
