         THIS RIDER, made the 17th day of September, 2002, is among The

         The Agreement is modified by the following:

         The Fund Manager shall maintain all books and records with respect to
the Government Securities Fund's portfolio transactions required by
subparagraphs (b)(5), (6), (7), (9), (10) and (11) and paragraph (f) of Rule
31a-1 under the Investment Company Act of 1940 ("the 1940 Act") and shall
render to the Fund's Board of Directors such periodic and special reports as
the Fund's Board of Directors may reasonably request. The Fund Manager shall
timely furnish to the Adviser all information relating to the Fund Manager's
services under this Agreement needed by the Adviser to keep the other books and
records of the Government Securities Fund required by Rule 31a-1 under the 1940
Act. The Fund Manager agrees that all records that it maintains on behalf of
the Government Securities Fund are property of the Government Securities Fund
and the Fund Manager will surrender promptly to the Government Securities Fund
any of such records upon the Government Securities Fund's request; provided,
however, that the Fund Manager may retain a copy of such records. The Fund
Manager further agrees to preserve for the periods prescribed by Rule 31a-2
under the 1940 Act any such records as are required to be maintained by it
pursuant to this Agreement. The Fund Manager shall perform a monthly
reconciliation of the Government Securities Fund to the holdings report
provided by the Fund's custodian and bring any material or significant
variances regarding holdings or valuations to the attention of the Adviser.

Agreement shall be construed accordingly.

         IN WITNESS WHEREOF, the parties hereof have caused this Rider to be
signed by their duly authorized officers and their corporate seals hereunto
affixed and attested as of the date first above written.
