Re:     Capital Properties, Inc.

Gentlemen:

Your letter of June 3, 2005, addressed to the Board of Directors of this Company
was presented at a meeting of the Board at which all of the Directors were
present.

Each Director is fully aware of his obligation as a director under the corporate
law of Rhode Island and the United States securities laws. No executive officer
or director, or any affiliate of any executive officer or director, has
purchased or sold shares of Capital Properties, Inc. since the date your tender
offer was initiated. At its meeting, the Board unanimously concluded that its
letter of May 16, 2005, presents all material information relating to its
assessment to take no position with respect to your tender offer

                                            Very truly yours,

                                            /s/ Robert H. Eder
                                            Robert H. Eder
                                            Chairman and Chief Executive Officer
