Dear Morton's Stockholder:

    TIME IS SHORT: TO ENSURE THAT YOUR VOTE IS COUNTED IN FAVOR OF RECEIVING
$17.00 PER SHARE IN CASH, WE URGE YOU TO SIGN, DATE AND RETURN THE ENCLOSED
WHITE PROXY CARD TODAY.

                             $17.00 CASH PER SHARE

    On July 15, 2002, Castle Harlan increased its offer for Morton's to $17.00
cash per share--the result of an active bidding process involving an affiliate
of Carl C. Icahn. The competing bids followed an open, fair and thorough
year-long effort to address stockholders' desire for liquidity and value
realization.

    Castle Harlan's $17.00 per share cash offer represents:

    - A premium of 49% over the closing market price of $11.44 on March 25,
      2002, the last full trading day before the parties entered into the
      original merger agreement, and a premium of 158% over the closing market
      price of $6.60 on February 14, 2002, the last full trading day before
      Castle Harlan submitted its initial proposal to acquire Morton's; and

    - Certain value, with significantly increased likelihood of completion soon
      after approval by stockholders.

    No higher offer has emerged after contact with over 30 potential buyers,
including Mr. Icahn, led by an independent Special Committee of the Board of
Directors.

    You may receive additional proxy materials from persons other than the
Company. TO ENSURE THAT, AT THE SPECIAL MEETING OF STOCKHOLDERS SCHEDULED FOR
JULY 23, 2002, YOUR VOTE IS COUNTED IN FAVOR OF RECEIVING $17.00 PER SHARE IN
CASH, WE URGE YOU TO SIGN, DATE AND RETURN ONLY THE WHITE PROXY CARD.

    If you have already returned your WHITE proxy card voting FOR approval of
the merger, please accept our sincere thanks for your support, and there is no
need for you to do anything further at this time to vote in favor of the merger
at the increased price. If you have not already returned your WHITE proxy card
or if you have previously voted AGAINST or to ABSTAIN with respect to the
earlier Castle Harlan offer, WE URGE YOU TO IMMEDIATELY VOTE FOR APPROVAL OF THE
MERGER IN LIGHT OF THE ENHANCED CASTLE HARLAN OFFER AND TO SIGN, DATE AND RETURN
THE ENCLOSED WHITE PROXY CARD IN THE ENCLOSED SELF-ADDRESSED ENVELOPE, WHICH
REQUIRES NO POSTAGE IF MAILED IN THE UNITED STATES.

    If you have any questions or need assistance in voting your shares, please
call Georgeson Shareholder Communications at (866) 300-8590. This toll-free
stockholder assistance number is staffed Monday through Friday from 9:00 a.m.
until 8:00 p.m. (Eastern Daylight Time).

                                          Sincerely,

                                          /s/ Allen J. Bernstein
