Based on the advice of current counsel, Dennis McGillicuddy is filing this Schedule 13D to amend and supplement the information as to the transactions previously reported on a Schedule 13G. Item 1. Security and Issuer. This statement on Schedule 13D (this "Statement") relates to the common stock, par value $.0001 per share (the "Common Stock"), of Franklin Street Properties Corp., a Maryland corporation ("FSP Corp."). The principal executive offices of FSP Corp. are located at 401 Edgewater Place, Suite 200, Wakefield, MA 01880-6210. Item 2. Identity and Background. Dennis J.

During the past five years, Mr. McGilliciddy has not been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). During the past five years, Mr. McGillicuddy was not a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration. No funds were borrowed by Mr. McGillicuddy or any related entity for the acquisition of FSP Common Stock. On June 1, 2003, FSP Corp. completed its acquisition of thirteen real estate investment trusts (collectively, the "Target REITs"), each a Delaware corporation. The acquisitions were completed pursuant to an Agreement and Plan of Merger, dated as of January 14, 2003 (the "Merger Agreement"), by and among FSP Corp. and the Target REITs. Upon consummation of the transactions contemplated by the Merger Agreement, each Target REIT was merged with and into FSP Corp., with FSP Corp. as the surviving corporation (the "Mergers"). Under the terms of the Merger Agreement each outstanding share of preferred stock, $0.01 par value per share ("Target Stock"), of each respective Target REIT, as of June 1, 2003, was converted into a specified number of shares of Common Stock. Under the terms of the Merger Agreement each outstanding share of common stock, $0.01 par value per share, of each respective Target REIT, as of June 1, 2003, was cancelled.
