         information acquired in the course of their work for personal

         any Material Violations. Requests for legal advice from a Senior
         Financial Officer to the Chief Legal Officer shall not be considered a
         report under this Code of Ethics unless the Senior Financial Officer
         has indicated to the Chief Legal Officer that he is making a report
         under this Code of Ethics. The reporting obligation of the Chief Legal
         Officer under this Code of Ethics is independent of any separate

         Procedures of the QLCC.

         accordance with the Procedures of the QLCC. If, in accordance with the
         Procedures of the QLCC, the QLCC concurs that a material Code of Ethics
         violation has occurred, it will inform and make a recommendation to the
         Trust's Board of Trustees, which will consider appropriate action,
         which may include review of, and appropriate modifications to,
         applicable policies and procedures; notification to appropriate
         personnel of the Trust's investment adviser, principal underwriter,
         administrator, transfer agent, custodian or accountant or their boards;

         the Trust.
