Mr. Kennedy is not elegible to receive benefits under the Executive Deferred Compensation Plan until five years after the plan year in which the contribution was made to his account, or such later date beyond five years as Mr. Hinman elects. ( 2 )The rabbi trust established in connection with the Executive Deferred Compensation Plan of Allianz Dresdner Asset Management of America LLC acquired common shares of beneficial interest in PIMCO Corporate Opportunity Fund for the Compensation Deferral Account maintained for the benefit of Mr. Hinman after a contribution to the plan made by Pacific Investment Management Company LLC, a subsidiary of Allianz Dresdner Asset Management of America LLC.
