The Trustees of each investment company named above have approved certain
changes to the Systematic Withdrawal Plan of each company, to take effect on
October 1, 1998. EFFECTIVE OCTOBER 1, 1998, the disclosure in the section of
each of the above Statements of Additional Information entitled "SHAREHOLDER
SERVICES -- Systematic Withdrawal Plan" is hereby replaced by the following:
Systematic Withdrawal Plan. As discussed in the Prospectus, a
systematic withdrawal plan (the "Withdrawal Plan") is available for
shareholders whose shares of TCW/DW Funds have an aggregate value of
$10,000 or more. Shares of any Fund from which redemptions will be made
pursuant to the Plan must have a value of $1,000 or more (referred to as a
"SWP Fund"). The required share values are determined on the date the
shareholder establishes the Withdrawal Plan. The Withdrawal Plan provides
for monthly, quarterly, semi-annual or annual payments in any amount not
less than $25, or in any whole percentage of the value of the SWP Funds'
shares, on an annualized basis. Any applicable contingent deferred sales
charge ("CDSC") will be i imposed on shares redeemed under the Withdrawal
Plan (see "Purchase of Fund Shares"), except that the CDSC, if any, will be
waived on redemptions under the Withdrawal Plan of up to 12% annually of
the value of each SWP Fund account, based on the share values next
determined after the shareholder establishes the Withdrawal Plan. (For
shareholders who established the Withdrawal Plan prior to October 1, 1998,
the value of each SWP Fund account for the purpose of the 12% CDSC waiver
will be determined at 4:00 p.m., New York time, on October 2, 1998.)
Redemptions for which this CDSC waiver policy applies may be in amounts up
to 1% per month, 3% per quarter, 6% semi-annually or 12% annually. Under
this CDSC waiver policy, amounts withdrawn each period will be paid by
first redeeming shares not subject to a CDSC because the shares were
purchased by the reinvestment of dividends or capital gains distributions,
the CDSC period has elapsed or some other waiver of the CDSC applies. If
shares subject to a CDSC must be redeemed, shares held for the longest
period of time will be redeemed first and continuing with shares held the
next longest period of time until shares held the shortest period of time
are redeemed. Any shareholder participating in the Withdrawal Plan will
have sufficient shares redeemed from his or her account so that the
proceeds (net of any applicable CDSC) to the shareholder will be the
designated monthly, quarterly, semi-annual or annual amount.
A shareholder may suspend or terminate participation in the Withdrawal
Plan at any time. A shareholder who has suspended participation may resume
payments under the Withdrawal Plan, without requiring a new determination
of the account value for the 12% CDSC waiver. The Withdrawal Plan may be
terminated or revised at any time by the Fund.
Prior to adding an additional SWP Fund to an existing Withdrawal Plan,
the required $10,000/$1,000 share values must be met, to be calculated on
the date the shareholder adds the additional SWP Fund. However, the
addition of a new SWP Fund will not change the account value for the 12%
CDSC waiver for the SWP Funds already participating in the Withdrawal Plan.
The Transfer Agent acts as agent for the shareholder in tendering to
the Fund for redemption sufficient full and fractional shares to provide
the amount of the periodic withdrawal payment designated in the
application. The shares will be redeemed at their net asset value
determined, at the shareholder's option, on the tenth or twenty-fifth day
(or next following business day) of the relevant month, quarter, or
semi-annual or annual period and normally a check for the proceeds will be
mailed by the Transfer Agent, or amounts credited to a shareholder's Dean
Witter Reynolds Inc. or other selected broker-dealer brokerage account, or
amounts deposited electronically into the shareholder's bank account via
the Automated Clearing House, within five business days after the date of
redemption.
Withdrawal Plan payments should not be considered as dividends, yields
or income. If periodic withdrawal plan payments continuously exceed net
investment income and net capital gains, the shareholder's original
investment will be correspondingly reduced and ultimately exhausted. Each
<PAGE>
withdrawal constitutes a redemption of shares and any gain or loss realized
must be recognized for federal income tax purposes. Although a shareholder
may make additional investments while participating in the Withdrawal Plan,
withdrawals made concurrently with purchases of additional shares are
inadvisable because of sales charges applicable to purchases or redemptions
of shares (see "Purchase of Fund Shares" in the Prospectus).
Any shareholder who wishes to have payments under the Withdrawal Plan
made to a third party, or sent to an address other than the one listed on
the account, must send complete written instructions to the Transfer Agent
to enroll in the Withdrawal Plan. The shareholder's signature on such
instructions must be guaranteed by an eligible guarantor acceptable to the
Transfer Agent (shareholders should contact the Transfer Agent for a
determination as to whether a particular institution is such an eligible
guarantor). A shareholder may, at any time, change the amount and interval
of withdrawal payments and the address to which checks are mailed through
his or her Morgan Stanley Dean Witter Financial Advisor or other selected
broker-dealer representative or by written notification to the Transfer
Agent. In addition, the party and/or the address to which checks are mailed
may be changed by written notification to the Transfer Agent, with
signature guarantees required in the manner described above. The
shareholder may also terminate the Withdrawal Plan at any time by written
notice to the Transfer Agent. In the event of such termination, the account
will be continued as a regular Shareholder Investment Account. The
shareholder may also redeem all or part of the shares held in the
Withdrawal Plan account (see "Repurchases and Redemption" in the
Prospectus) at any time. Shareholders wishing to enroll in the Withdrawal
Plan should contact their Morgan Stanley Dean Witter Financial Advisor or
other selected broker-dealer representative.
