* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On May 8, 2009, the Douglas S. Schatz and Jill E. Schatz Family Trust entered into a series of variable prepaid forward contracts with a securities broker. The Family Trust's orders in respect of two of such contracts, relating to 150,000 and 200,000 shares of AEIS common stock, respectively, became binding on the Family Trust as of May 18, 2009 and May 19, 2009, respectively. When each of such orders has been fulfilled, the broker will deliver to the Family Trust a cash payment equal to approximately 84% of the market value of the respective shares. Upon settlement of the first order listed above, the date of which will be one year plus two weeks following the date the order has been fulfilled, the Family Trust may deliver to the broker between 120,000 and 150,000 shares of AEIS common stock, depending on the market price of the AEIS common stock on the two trading days prior to the settlement date.
(2) Upon settlement of the second order listed above, the date of which will be 18 months following the date the order has been fulfilled, the Family Trust may deliver to the broker between 160,000 and 200,000 shares of AEIS common stock, depending on the market price of the AEIS common stock on the two trading days prior to the settlement date. In the alternative, at the Family Trust's option, the Family Trust may deliver cash in an amount equal to the fair market value of the shares that the Family Trust would otherwise deliver upon the respective settlement dates. Accordingly, the Family Trust may retain some or all of the shares subject to the contracts.
(3) The Family Trust has pledged to the securities broker an aggregate of 350,000 shares of the common stock held directly by the Family Trust, to secure the Family Trust's performance of the two above-mentioned orders under the contracts upon settlement; however, unless and until common stock is delivered to the securities broker upon settlement of such contracts, the Family Trust will retain all voting and dividend rights in respect of such shares. In connection with the Family Trust's pledge of 350,000 shares to the securities broker, Silicon Valley Bank released such shares from the pledge agreement under which the Family Trust previously had pledged such shares to Silicon Valley Bank as collateral for a line of credit entered into by the Family Trust, Douglas Schatz and Jill Schatz. All other shares of AEI common stock held directly by the Family Trust and pledged to Silicon Valley Bank as of May 19, 2009 remain pledged as collateral for the Silicon Valley Bank line of credit.
(4) The remaining variable prepaid forward contracts entered into by the Family Trust on May 8, 2009 relate to an additional 300,000 shares. The Family Trust has paid an affiliate of the securities broker a fee in connection with the variable prepaid forward contracts.
(5) The shares subject to the variable prepaid forward contracts are owned directly by the Douglas S. Schatz & Jill E. Schatz Family Trust, a ten percent owner of the issuer, and indirectly by Douglas S. Schatz and Jill E. Schatz, co-trustees of the trust. Douglas S. Schatz is Chairman of the Board of the issuer.
