NOTE D - DISSOLUTION OF PHILADEP

In January 2001, Philadep adopted a Plan of Voluntary Dissolution (the Plan) providing for the cessation of Philadep’s corporate existence pursuant to the Pennsylvania Banking Code of 1965. In connection with the Plan, in February 2001, Philadep and the Exchange entered into an Assumption and Guarantee Agreement (the Assumption Agreement) providing for the Exchange to discharge certain obligations of Philadep not discharged directly by Philadep. Pursuant to the Assumption Agreement, the Exchange assumed Philadep’s obligations under its pension and/or post-retirement benefit plans.

As of December 31, 2002 (the “Final Distribution Date”), by virtue of the Plan and the Assumption Agreement, all funds, assets, and liabilities of Philadep, with a net asset value of $2,185,800, were assigned to and assumed by the Exchange. In 2005, Philadep received tax clearance from the Commonwealth of Pennsylvania and filed Articles of Dissolution with the Pennsylvania Department of Banking which were approved by the Department of Banking in 2006, causing Philadep to be dissolved. In December 2002, the SEC issued an order approving Philadep’s request to withdraw as a registered clearing agency effective as of December 31, 2002. The SEC required Philadep to keep a minimum reserve of $300,000 to cover potential reorganization claims. In 2000, Philadep was authorized by the SEC to amortize the $300,000 reserve to income over a three-year period.
