Item 5.03. Amendments to Articles of Incorporation or Bylaws;
           Change in Fiscal Year.

      Effective May 12, 2006, Franklin Street Properties Corp. (the
"Registrant") amended its Bylaws to (i) authorize its secretary to provide
notice to stockholders by electronic means and (ii) permit stockholders to
authorize another person to act as a proxy by transmitting, or authorizing the
transmission of, an authorization for the person to act as a proxy to the person
authorized to act as proxy or any other person authorized to receive the proxy
authorization on behalf of the person authorized to act as the proxy, including
a proxy solicitation firm or proxy support service organization, which
authorization may be transmitted by telegram, cablegram, datagram, electronic
mail or any other electronic or telephonic means.

Article II, Section 4 (Notice) previously read as follows:

            "Not less than ten nor more than 90 days before each meeting of
            stockholders, the secretary shall give to each stockholder entitled
            to vote at such meeting and to each stockholder not entitled to vote
            who is entitled to notice of the meeting written or printed notice
            stating the time and place of the meeting and, in the case of a
            special meeting or as otherwise may be required by statute, the
            purpose for which the meeting is called, by either mail or by
            presenting it to such stockholder personally or by leaving it at his
            residence or usual place of business. If mailed, such notice shall
            be deemed to be given when deposited in the United States mail
            addressed to the stockholder at his post office address as it
            appears on the records of the Corporation, with postage thereon
            prepaid."

and has been amended to read as follows:

            "Not less than ten nor more than 90 days before each meeting of
            stockholders, the secretary shall give notice in writing or by
            electronic transmission to each stockholder entitled to vote at such
            meeting and to each stockholder not entitled to vote but who is
            entitled to notice of the meeting stating the time and place of the
            meeting and, in the case of a special meeting or as otherwise may be
            required by statute, the purpose for which the meeting is called, by
            electronic transmission, mail or by presenting it to such
            stockholder personally or by leaving it at his residence or usual
            place of business. If mailed, such notice shall be deemed to be
            given when deposited in the United States mail addressed to the
            stockholder at his post office address as it appears on the records
            of the Corporation, with postage thereon prepaid. If sent by
            electronic transmission, such notice shall be deemed to be given
            when transmitted to the stockholder by an electronic transmission to
            any address or number of the stockholder at which the stockholder
            receives electronic transmissions. For purposes of this Section 4,
            any reference to "electronic transmission" shall have the meaning
            ascribed thereto in Section 1-101 of the Maryland General
            Corporation Law (as the same may be amended from time to time) or
            any successor statute."


                                        2


Article II, Section 9 (Proxies) previously read as follows:

            "Each stockholder of record entitled to vote at a meeting of
            stockholders or to express consent or dissent to corporate action in
            writing without a meeting, may vote or express such consent or
            dissent in person or may authorize another person or persons to vote
            or act for him by a proxy executed in writing by the stockholder or
            his duly authorized attorney in fact. Such proxy shall be filed with
            the Secretary of the Corporation before or at the time of the
            meeting. No proxy shall be valid after eleven months from the date
            of its authorization, unless otherwise provided in the proxy."

and has been amended to read as follows:

            "(a) Each stockholder of record entitled to vote at a meeting of
            stockholders or to express consent or dissent to corporate action in
            writing without a meeting, may vote or express such consent or
            dissent in person or may authorize another Person or Persons (as
            defined in Section 9(e) below) to vote or act for him by a proxy as
            provided in this Section 9. Such proxy shall be filed with the
            Secretary of the Corporation before or at the time of the meeting.
            No proxy shall be valid after eleven months from the date of its
            authorization, unless otherwise provided in the proxy.

            (b) A stockholder may sign a writing authorizing another Person to
            act as proxy. Signing may be accomplished by the stockholder or the
            stockholder's authorized agent signing the writing or causing the
            stockholder's signature to be affixed to the writing by any
            reasonable means, including facsimile signature.

            (c) A stockholder may authorize another Person to act as a proxy by
            transmitting, or authorizing the transmission of, an authorization
            for the Person to act as a proxy to the Person authorized to act as
            proxy or any other Person authorized to receive the proxy
            authorization on behalf of the Person authorized to act as the
            proxy, including a proxy solicitation firm or proxy support service
            organization. The authorization may be transmitted by telegram,
            cablegram, datagram, electronic mail or any other electronic or
            telephonic means.

            (d) A copy, facsimile telecommunication or other reliable
            reproduction of the writing or transmission authorized under
            Sections 9(b) and (c) may be substituted for the original writing or
            transmission for any purpose for which the original writing or
            transmission could be used.

            (e) For purposes of this Section 9, any reference to "Person" shall
            have the meaning ascribed thereto in Section 1-101 of the Maryland
            General Corporation Law (as the same may be amended from time to
            time) or any successor statute."
