Dear Stockholder:

As a stockholder of Neuberger Berman Real Estate Securities Income Fund Inc.,
you were recently sent a proxy statement and card that asked you to vote to
elect Class II directors.  Unfortunately, the proxy card you received was
incomplete and did not offer you the opportunity to vote for all of the
directors that you, as a stockholder of that fund, are entitled to elect.

If you already voted your shares, we thank you for your prompt attention to
this matter, but must ask you to vote again using the enclosed card. If you
haven't yet submitted your vote, please use the enclosed card and disregard the
card from the earlier mailing.  We are also enclosing the proxy statement for
your information.

We apologize for this inconvenience.  If you have any questions regarding this
matter, please call 877-461-1899.


Sincerely,

/s/ Peter E. Sundman
