EXHIBIT (A)(6)
VAN KAMPEN SENIOR FLOATING RATE FUND
Supplement dated August 3, 2000
To the Offer to Purchase, dated July 21, 2000 and
Letter of Transmittal, dated July 21, 2000
The Offer to Purchase, the Letter of Transmittal and ancillary offer
documents of the Van Kampen Senior Floating Rate Fund (the "Trust") are hereby
supplemented to state that the Trust is offering to purchase up to 49,664,475 of
its Common Shares pursuant to the terms of the Offer. Terms not defined in this
supplement shall have the same meanings as defined in the Offer to Purchase and
the related Letter of Transmittal. All references to the number of Common Shares
subject to the Offer should be changed to 49,664,475. The cost of purchasing the
full 49,664,475 Common Shares pursuant to the Offer would be approximately
$478,765,539 (assuming an NAV of $9.64 per Common Share on the Expiration Date).
If more than 49,664,475 Common Shares are duly tendered prior to the expiration
of the Offer, the Trust presently intends to, assuming no changes in the factors
originally considered by the Board of Trustees when it determined to make the
Offer and the other conditions set forth in the Offer, but is not obligated to,
extend the Offer period, if necessary, and increase the number of Common Shares
that the Trust is offering to purchase to an amount which it believes will be
sufficient to accommodate the excess Common Shares tendered as well as any
Common Shares tendered during the extended Offer period or purchase 49,664,475
Common Shares (or such greater number of Common Shares sought) on a pro rata
basis.
