Dear Morton's Stockholder:

    You have been invited to attend a special meeting of stockholders at
9:00 a.m. (local time) on Tuesday, July 23, 2002, at The Garden City Hotel, 45
Seventh Street, Garden City, New York 11530, where you will have the opportunity
to vote on the Company's definitive agreement to be acquired by an affiliate of
Castle Harlan Partners III, L.P., a private equity investment firm. The enclosed
proxy statement describes the proposed transaction in detail.

    The Castle Harlan offer is the best offer to emerge from a year-long process
launched specifically to address investors' desire for liquidity and value
realization. The process was open, fair and thorough. It was conducted by a
Special Committee of the Board composed solely of directors who are not officers
of Morton's advised by its own independent financial and legal advisors. At
least 30 possible buyers had contact with the Special Committee's financial
advisors.

    Under the terms of the agreement with Castle Harlan, Morton's stockholders
would receive $13.50 in cash for each share of common stock they hold. At this
price, Morton's total enterprise value is approximately $154 million, including
assumption of debt. The purchase price represents a premium of approximately
18.0% over the market closing price of $11.44 on March 25, 2002, the last full
trading day before the parties entered into the merger agreement, and a premium
of approximately 104.5% over the market closing price of $6.60 on February 14,
2002, the last full trading day before Castle Harlan submitted its initial
$12.00 per share proposal to acquire Morton's.

    The Board of Directors, based in part on the unanimous recommendation of the
Special Committee and the opinion of its financial advisor Greenhill & Co., LLC,
determined that the merger is fair to and in the best interests of Morton's and
its unaffiliated stockholders and has approved and adopted the merger agreement
and approved the merger. WE URGE YOU TO VOTE FOR THE MERGER BY SIGNING, DATING
AND RETURNING THE ENCLOSED WHITE PROXY CARD.

MORTON'S UNCERTAIN FUTURE AS A STAND-ALONE PUBLIC COMPANY

    You should know that in recommending the Castle Harlan acquisition to the
Board, the Special Committee, together with its outside advisors, carefully
analyzed the risks of Morton's prospects going forward as a stand-alone public
company and concluded that a sale now represents a better alternative for
stockholders. In reaching this decision, the Special Committee determined that:

    - Morton's business continues to suffer weak revenue trends and negative
      comparable restaurant revenues in its market segment as a result of the
      severe nationwide impact of the September 11, 2001 terrorist attacks, the
      continuing impact of the troubled economy, unfavorable business
      conditions, corporate spending cutbacks and reduced business travel. The
      Company believes that if such unfavorable conditions continue, or worsen,
      future results will also be adversely affected, the full extent of which
      cannot be determined or forecasted at this time.

    - Morton's deteriorating performance precipitated an amendment to its bank
      credit agreement, imposing significant restrictions on Morton's operating
      flexibility and capital expenditures. These restrictions will dramatically
      curtail our growth plans for the foreseeable future. The loan is currently
      being managed by the workout group at Fleet National Bank.

    - Morton's high debt load, low stockholder liquidity and small scale, when
      combined with other factors, presents significant risks to continued
      stand-alone operation and share value.

    - Morton's has received notice from the New York Stock Exchange that the
      Company is below NYSE listing standards and that the NYSE may delist the
      stock.

    The Special Committee weighed these considerations carefully in making its
recommendation to the Board in favor of the Castle Harlan transaction,
concluding that the proposed transaction is the best alternative for
stockholders and eliminates this risk and uncertainty by giving stockholders
immediate cash for their investment at a fair price.

FLORESCUE'S FICTION: NOTHING BUT MISLEADING RHETORIC

    You no doubt have heard that stockholder Barry Florescue and his company,
BFMA Holding Corporation, have indicated their intent to solicit proxies against
the offer. Despite all his misleading rhetoric, the fact remains: No higher
offer than Castle Harlan's $13.50 offer has emerged. Mr. Florescue now merely
claims he is "exploring alternatives" to raise additional financing for an
acquisition. Further, he was invited to participate in the sale process. He
refused. Clearly, we disagree with Mr. Florescue's views and we believe the
record demonstrates that his representation of the sale process is simply wrong.

    You should also know that on May 21, 2002, Morton's received a letter from
Carl C. Icahn stating that he was prepared to enter into a merger agreement with
Morton's at a price of $13.50 per share. After a preliminary exchange of
information, High River Limited Partnership, an affiliate of Mr. Icahn, and
Morton's entered into a confidentiality agreement on June 3, 2002, and High
River delivered a signed merger agreement to the Special Committee on June 14,
2002.

    As required under the Castle Harlan merger agreement, Morton's promptly
notified Castle Harlan of the Icahn binding offer. Castle Harlan then offered to
raise the price per share in its merger agreement from $12.60 to $13.50 and to
remove the closing condition that would have otherwise required Morton's to
achieve a minimum level of earnings. On June 15, 2002, Morton's Special
Committee and Board of Directors approved these changes, and Morton's signed the
related amendment to the Castle Harlan merger agreement.

    Please read the enclosed proxy statement carefully. Your vote is very
important. The merger cannot be completed unless the holders of a majority of
the outstanding shares of Morton's common stock entitled to vote approve and
adopt the merger agreement and approve the merger.

    With Morton's continuing to confront very challenging and uncertain business
conditions, your Board of Directors believes this merger represents the best
alternative for you, our stockholders. THEREFORE, WE URGE YOU TO VOTE FOR THE
TRANSACTION BY SIGNING, DATING AND RETURNING THE ENCLOSED WHITE PROXY CARD.

                                          Sincerely,

                                          /s/ Allen J. Bernstein
                                          Allen J. Bernstein
                                          Chief Executive Officer

                                       2
