Munder Money Market Fund 480 Pierce Street, Birmingham, Michigan 48009 November 25, 2002 Dear Shareholder: With the Special Meeting of Shareholders scheduled to take place on December 11, 2002, we thought you should be aware of some additional steps that Munder Capital Management ("Munder") has taken to increase the Money Market Fund's yields. Since July 3, 2002, Munder has been waiving a portion of the advisory fee it receives from the Fund in an effort to keep the seven-day yields for the Class B and Class C shares at approximately 0.10%. In order to achieve this goal, the amount waived and/or reimbursed by Munder was initially fairly small but, as a result of the declining interest rate environment, has steadily increased so that currently the waivers and/or reimbursements made by Munder are in excess of 0.50% of Money Market Fund's average daily net assets. As previously indicated in the Proxy Statement provided to you, this difficult yield environment is one of the primary reasons that the Board of Directors has recommended the proposed merger of the Money Market Fund with and into the Munder Cash Investment Fund. It is the current intention of Munder to keep the Money Market Fund's seven-day yields for the Class B and Class C shares at approximately 0.10% until the Fund has been merged with and into the Munder Cash Investment Fund. Please bear in mind that this merger cannot be completed without shareholder approval.
