With respect to any uncertificated securities or any Collateral held by a securities intermediary, commodity intermediary, or other financial intermediary of any kind, the Debtor shall execute and deliver, and shall cause any such issuer or intermediary to execute and deliver, an agreement among the Debtor, the Secured Party, and such issuer or intermediary in form and substance reasonably satisfactory to the Secured Party which provides, among other things, for the issuer’s or intermediary’s agreement that it shall comply with entitlement orders, and apply any value distributed on account of any such Collateral, as directed by the Secured Party without further consent by the Debtor.

(d) Unless and until a Default has occurred and is continuing, the Debtor may sell or otherwise dispose of any Investment Property constituting Collateral. After the occurrence and during the continuation of any Default, the Debtor shall not sell all or any part of the Investment Property constituting Collateral without the prior written consent of the Secured Party.

(e) The Debtor represents that as of April 30, 2004, none of the Investment Property constituting Collateral consists of margin stock (as such term is defined in Regulation U of the Board of Governors of the Federal Reserve System) except to the extent the Debtor has delivered to the Secured Party a duly executed and

Without limiting the foregoing, the Secured Party shall have the right to exchange, at its discretion, any and all of the Investment Property constituting Collateral upon the merger, consolidation, reorganization, recapitalization, or other readjustment of the respective issuer thereof or upon the exercise by or on behalf of any such issuer or the Secured Party of any right, privilege, or option pertaining to any Investment Property constituting Collateral and, in connection therewith, to deposit and deliver any and all of the Investment Property constituting

Collateral with any committee, depositary, transfer agent, registrar, or other designated agency upon such terms and conditions as the Secured Party may determine. In the event the Secured Party in good faith believes any of the Collateral constitutes restricted securities within the meaning of any applicable securities laws, any disposition thereof in compliance with such laws shall not render the disposition commercially unreasonable.”

SECTION 2. CONDITIONS PRECEDENT.

2.1. The Debtor and the Secured Party shall have executed and delivered this Amendment.

2.2. Legal matters incident to the execution and delivery of this Amendment shall be reasonably satisfactory to the Secured Party and its counsel.

SECTION 3. REPRESENTATIONS.
