            For the Annual Meeting of Stockholders on April 29, 2005

                                  INTRODUCTION

General Information

      This Proxy Statement is furnished in connection with the solicitation of
proxies by the Board of Directors of Franklin Street Properties Corp. (the
"Company") for use at the Annual Meeting of Stockholders to be held on April 29,
2005, and at any adjournment of that meeting. All proxies will be voted in
accordance with the stockholders' instructions, and, if no choice is specified,
the proxies will be voted in favor of the matters set forth in the accompanying
Notice of Meeting. Any proxy may be revoked by a stockholder at any time before
its exercise by delivery of written revocation or a subsequently dated proxy to
the Secretary of the Company or by voting in person at the Annual Meeting.

      The Company's Annual Report for the fiscal year ended December 31, 2004 is
being mailed to stockholders with the mailing of these proxy materials on or
about March 29, 2005.

Quorum Requirement

      At the close of business on March 22, 2005, the record date for the
determination of stockholders entitled to notice of and to vote at the Annual
Meeting, there were outstanding and entitled to vote an aggregate of 49,631,513
shares of Common Stock of the Company, constituting all of the outstanding
voting stock of the Company. Holders of Common Stock are entitled to one vote
per share.

      The holders of a majority of the number of shares of Common Stock issued,
outstanding and entitled to vote at the Annual Meeting will constitute a quorum
for the transaction of business at the Annual Meeting. Shares of Common Stock
represented in person or by proxy (including shares that abstain or otherwise do
not vote with respect to one or more of the matters presented for stockholder
approval) will be counted for purposes of determining whether a quorum is
present at the Annual Meeting.

Votes Required

      The affirmative vote of the holders of a plurality of the votes cast by
the holders of Common Stock is required for the election of directors.

      Shares that abstain from voting as to a particular matter, and shares held
in "street name" by a broker or nominee that indicates on a proxy that it does
not have discretionary authority to vote as to a particular matter, will not be
voted in favor of such matter, and also will not be counted as shares voting on
such matter. Accordingly, abstentions and "broker non-votes" will have no effect
on the voting on a matter that requires the affirmative vote of a certain
percentage of the votes cast or the shares voting on that matter.


                                       3

                              ELECTION OF DIRECTORS

Members of the Board of Directors

      The Company's Board of Directors is divided into three classes, with
members of each class holding office for staggered three-year terms. There are
currently two Class I Directors, whose terms expire at the 2007 Annual Meeting
of Stockholders, three Class II Directors, whose terms expire at the 2006 Annual
Meeting of Stockholders, and two Class III Directors, whose terms expire at the
this Annual Meeting of Stockholders (in all cases subject to the election and
qualification of their successors or to their earlier death, resignation or
removal).

      Richard Norris, currently a Class III Director, anticipates retiring from
the Company within the next three years, prior to the expiration of a new term.
Mr. Norris believes that one of his primary contributions as a director relates
to his ongoing involvement in the Company's investment banking business as an
Executive Officer. Once retired and, consequently, not conducting this job
day-to-day, Mr. Norris believes his value to the Board and to the Company's
stockholders would be diminished.

      The persons named in the enclosed proxy will vote to elect each of George
J. Carter and Georgia Murray as Class III Directors, unless authority to vote
for the election of the nominees is withheld by marking the proxy to that
effect. Mr. Carter is currently a Class III Director of the Company. Ms. Murray
has not previously served as a Director of the Company. Each of Mr. Carter and
Ms. Murray has indicated his or her willingness to serve, if elected, but if
either of them should be unable or unwilling to stand for election, the persons
named in the enclosed proxy may vote for election of a substitute nominee
designated by the Board of Directors. Proxies may not be voted for a greater
number of persons than the number of nominees named herein.

      Set forth below are the names and certain information with respect to each
director of the Company, including the nominees for election as Class III
Directors.

Board and Committee Meetings

      The Company's Board of Directors held six meetings during 2004, and acted
on one occasion by unanimous written consent. Each of the directors attended at
least 75% of the aggregate of (i) the total number of meetings of the Board of
Directors and (ii) the total number of meetings held by all committees of the
Board on which he or she served, in each case during the period that he or she
served. The Board has an informal policy that all directors are expected to
attend the annual meeting of stockholders. All directors attended the 2004
annual meeting of stockholders.

      In November 2004, the Company applied to have its Common Stock listed on
the American Stock Exchange; the application was approved in early 2005. Under
American Stock Exchange rules, a director of the Company will only qualify as
"independent" if the Company's Board of Directors affirmatively determines that
the director does not have a material relationship with the listed company that
would interfere with the exercise of independent judgment. The Company's Board
of Directors has determined that none of Messrs. Burke, McGillicuddy, or
Silverstein has a material relationship with the Company and that each of these
directors is "independent" as determined under Section 121 of the American Stock
Exchange Company Guide. The Company believes that Ms. Murray will qualify as an
independent director and expects that the Company's Board of Directors will make
a determination to that effect at its next meeting.

      The Company has a standing Audit Committee of the Board of Directors. The
Audit Committee amended its charter in October 2004. The amended and restated
charter is attached to this proxy statement as Appendix A. The Audit Committee
is responsible for, among other things, reviewing financial reports, accounting
procedures and the scope and results of the annual audit of the Company's
financial statements and overseeing the qualifications and independence of the
Company's independent auditors. The current members of the Audit Committee are
Mr. Burke, who serves as Chairman, Mr. McGillicuddy and Mr. Silverstein.

      The Board of Directors has determined that all of the members of the Audit
Committee are "independent" under the listing standards of the American Stock
Exchange and contemplated by Rule 10A-3 under the Securities Exchange Act. The
Board of Directors has determined that each member of the Audit Committee is
able to read and understand fundamental financial statements, including a
company's balance sheet, income statement, and cash flow statements, and that
Mr. Burke, the Chairman of the committee, is qualified as an "audit committee
financial expert" as the term is defined in Item 401(h) of Regulation S-K,
promulgated by the Securities and Exchange Commission. The members of the Audit
Committee met four times in 2004.

      The Company has a standing Compensation Committee of the Board of
Directors, which was formed in July 2002. The Compensation Committee is
responsible for reviewing compensation issues and making decisions concerning
the compensation of the Company's executive officers. The current members of the
Compensation Committee are Messrs. McGillicuddy and Silverstein and Ms.
Fournier. The members of the Compensation Committee met once in 2004, and acted
on one occasion by unanimous written consent.


                                       8


      The Company does not have a standing nominating committee. The Board of
Directors has determined that it is appropriate for the Company not to have a
nominating committee because all of the matters which a nominating committee
would be responsible for are presently considered by all the members of the
Board of Directors. Each member of the Board of Directors participates in the
consideration of director nominees.

Director Candidates

      The process followed by the Board of Directors to identify and evaluate
director candidates includes requests to Board members and others for
recommendations, meetings from time to time to evaluate biographical information
and background material relating to potential candidates and interviews of
selected candidates by members of the Board.

      In considering whether to recommend any particular candidate for inclusion
in its slate of recommended director nominees, the Board of Directors applies
criteria including the candidate's integrity, business acumen, knowledge of the
Company's business and industry, age, experience, diligence, conflicts of
interest and the ability to act in the interests of all stockholders. The Board
does not assign specific weights to particular criteria and no particular
criterion is a prerequisite for each prospective nominee. The Board believes
that the backgrounds and qualifications of its directors, considered as a group,
should provide a composite mix of experience, knowledge and abilities that will
allow the Board to fulfill its responsibilities. These criteria were used by the
Board in consideration of Ms. Murray, who was originally proposed as a nominee
by an executive officer of the Company.

      Stockholders may recommend individuals to the Board for consideration as
potential director candidates by submitting their names, together with
appropriate biographical information and background materials to the Company at
its principal office, Attn: Barbara J. Fournier, Secretary. Assuming that


                                       9


appropriate biographical and background material has been provided on a timely
basis, the Committee will evaluate stockholder-recommended candidates by
following substantially the same process, and applying substantially the same
criteria, as it follows for candidates submitted by others. If the Board
determines to nominate a stockholder-recommended candidate and recommends his or
her election, then his or her name will be included in the Company's proxy card
for the next annual meeting.

      Stockholders also have the right under the Company's bylaws to directly
nominate director candidates, without any action or recommendation on the part
of the Board, by following the procedures set forth below under "Stockholder
Proposals." Candidates nominated by stockholders in accordance with the
procedures set forth in the bylaws will not be included in the Company's proxy
card for the next annual meeting.

Communicating with the Board of Directors

      The Board will give appropriate attention to written communications that
are submitted by stockholders, and will respond if and as appropriate. The
Secretary of the Company is primarily responsible for monitoring communications
from stockholders and for providing copies or summaries to the other directors
as he or she considers appropriate.

      Communications are forwarded to all directors if they relate to important
substantive matters and include suggestions or comments that the Secretary
considers to be important for the directors to know. In general, communications
relating to corporate governance and long-term corporate strategy are more
likely to be forwarded than communications relating to ordinary business
affairs, personal grievances and matters as to which the Company tends to
receive repetitive or duplicative communications.

      Stockholders who wish to send communications on any topic to the Board
should address such communications to Board of Directors, Franklin Street
Properties Corp., 401 Edgewater Place, Suite 200, Wakefield, Massachusetts
01880, Attn: Barbara J. Fournier, Secretary.

Compensation of Directors

      The Company compensates its non-management directors for their services as
directors in the annual amount of $55,000, plus an additional $10,000 annually
for the Chair of the Audit Committee. The Company also reimburses its
non-management directors for expenses incurred by them in connection with
attendance at Board meetings.

Compensation Committee Interlocks and Insider Participation

      The Compensation Committee is comprised of Messrs. McGillicuddy and
Silverstein and Ms. Fournier. Ms. Fournier is the Vice-President, Chief
Operating Officer, Treasurer and Secretary of the Company. No executive officer
of the Company has served as a director or member of the compensation committee
(or other committee serving an equivalent function, or in the absence of any
such committee, the entire board of directors) of any other entity, that has one
of its executive officers serving or having served as a director or member of
the Compensation Committee of the Company.

Report of the Compensation Committee on Executive Compensation

      The Compensation Committee (the "Committee") is responsible for
determining the compensation package of each executive officer and establishes
compensation policies for the Company's Chief Executive Officer and the other
executive officers of the Company.

      The Company's executive compensation program is designed to promote the
achievement of the Company's business goals and, thereby, to maximize corporate
performance and stockholder returns.

      The executive officers of the Company fall into two categories. The first
category is comprised of executive officers who make up the corporate management
team (i.e., CEO, Chief Operating Officer, subsidiary president, etc.). The
second category is comprised of executive officers who are Investment Executives
and are engaged in the sale of equity interests in the Company's Sponsored
REITs.

      Executive compensation for the corporate management team generally
consists of a combination of base salary, cash performance bonuses and the
potential for awards of stock through the Company's 2002 Stock Incentive Plan.
The Committee considers stock incentives to be a critical component of an
executive's compensation package in order to help align executive interests with
stockholder interests.

      Executive compensation for the Company's executive officers who are
Investment Executives consists primarily of commissions earned on the sale of
interests in the Company's Sponsored REITs. As is standard practice in the
investment industry, Investment Executives earn as commission a percentage of
payout of the gross sales commission earned on each investment sale. The actual
amount of compensation earned as commissions is determined by the level of sales
conducted by each individual. An investment executive's ability to earn
commissions is limited only by the amount of equity available to be sold and his
individual ability to sell it. As such, the Committee does not set the level of
compensation for the executive officers who are Investment Executives. The
Committee does determine the percentage of payout that is paid to the Investment
Executives as commission.


                                       13


      Compensation Philosophy

      The objectives of the executive compensation program are to align
compensation with business objectives and individual performance and to enable
the Company to attract, retain and reward executive officers who are expected to
contribute to the long-term success of the Company. The Company's executive
compensation philosophy is based on the principles of competitive and fair
compensation and sustained performance.

      Competitive and Fair Compensation

      The Committee is committed to providing an executive compensation program
that helps attract and retain highly qualified executives. To ensure that total
cash compensation (salary plus cash bonus) is competitive, the Committee
compares its compensation practices with those of other companies in the
industry and sets its compensation guidelines based on this review. The
Committee believes total cash compensation for its executive officers is within
the range of total cash compensation paid to executives with comparable
qualifications, experience and responsibilities in the same or similar business
and of comparable size and success. The Company also strives to achieve
equitable relationships both among the compensation of individual officers and
between the compensation of officers and other employees throughout the
organization.

      Sustained Performance

      Executive officers who are part of the corporate management team are
rewarded based upon corporate performance and individual performance. Corporate
performance is evaluated by reviewing the extent to which strategic and business
plan goals are met, including such factors as levels of property acquisitions,
performance of properties in the Company's portfolio, gains or losses on
property dispositions, levels of equity sales and the achievement of earnings,
cash available for distribution, or CAD, and dividend goals. Individual
performance is evaluated by reviewing the attainment of specified individual
objectives and the degree to which teamwork and Company values are fostered.

      In evaluating each management executive's performance, the Company
generally follows the following process:

      o     Company and individual goals and objectives generally are set at the
            beginning of a calendar/fiscal year.

      o     At the end of the year, the accomplishment of the executive's goals
            and objectives and his/her contributions to the Company are
            evaluated, and the results are communicated to the executive.

      o     The comparative results, compared with comparative compensation
            practices of other companies in the industry, are then used to
            determine cash bonus and stock compensation levels, if any.


                                       14


      Any increases in annual salaries and payment of bonus awards are based on
actual corporate and individual performance against targeted performance and
various subjective performance criteria. Targeted performance criteria vary for
each executive based on his/her area of responsibility, and may include
achievement of specific acquisition goals, achievement of specific property
performance goals, continued innovation in development of the Company's
infrastructure, achievement of the operating budget for the Company as a whole
or of a business group of the Company, and achievement of specific earnings, CAD
and dividends goals. Subjective performance criteria include an executive's
ability to motivate others, develop the skills necessary to grow as the Company
matures, recognize and pursue new business opportunities and initiate programs
to enhance the Company's growth and success. The Committee does not use a
specific formula based on these targeted performance and subjective criteria,
but instead makes an evaluation of each executive officer's contribution in
light of all such criteria.

      Compensation at the management executive level has also included the award
of stock in the Company. The stock award program is designed to promote the
identity of long-term interests between the Company's employees and its
stockholders. The size of the stock award is generally intended to reflect the
executive's position with the Company and his/her contribution to the Company,
including his/her success in achieving the individual performance criteria
described above.

      Mr. Carter's 2004 Compensation

      Mr. Carter is the CEO of the Company. Mr. Carter participates in the same
executive compensation plans available to the other executive officers of the
Company. Mr. Carter's base salary for 2004 was $225,000. The Committee
determined that Mr. Carter performed very well in an otherwise very difficult
commercial real estate environment, specifically, that the two major markets in
which the Company operates, commercial real estate operations and investment
banking, continued to be in recession during 2004. As a result, the Company
failed to meet certain of its financial goals for 2004. At the request of Mr.
Carter, the Compensation Committee did not consider making any recommendation to
the Board for a cash bonus for 2004. Mr. Carter was also not awarded any stock
as compensation for his 2004 performance.

      The Committee determined that the Company's failure to meet certain of its
financial goals was not reflective of Mr. Carter's overall performance, which
was considered excellent by the Compensation Committee. The Committee made a
special note as to the value to the Company of Mr. Carter's maintaining his
focus and discipline. Based upon numerous performance measurements, the
Committee felt that the Company had a positive year, which included the
Company's:

      o     generating an increase in net income over the previous year;

      o     maintaining the level of dividends paid to shareholders of the
            Company for the third straight year (not including the "special"
            dividend paid in 2003);

      o     completing the acquisition on behalf of Sponsored REITs of seven new
            operating properties;


                                       15


      o     completing seven syndications of preferred stock on behalf of
            Sponsored REITs totaling in excess of $213 million in equity;

      o     generating operating results that produced an increase in estimated
            valuation of the Company's Common Stock of approximately 7.6% over
            the prior year's estimated valuation;

      o     successfully recruiting one new, non-management member of the Board
            of Directors to serve as chairman of the Audit Committee; and

      o     applying to the American Stock Exchange to list the Company's Common
            Stock, which application was approved in early 2005.


                           By the Compensation Committee

                           Dennis J. McGillicuddy, Chairman
                           Barry Silverstein
                           Barbara J. Fournier


                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Messrs. Carter, MacPhee, Norris and Gribbell and Mses. Fournier and
Notopoulos, each of whom is an executive officer of the Company, serve, at the
request of the Company, as executive officers and, except for Ms. Notopoulos,
directors of each of the Sponsored REITs. Ms. Notopolous serves as a director of
certain of the Sponsored REITs. None of such persons receives any remuneration
from the Sponsored REITs for such service. On August 13, 2004, the Company
entered into a merger agreement to acquire four of these Sponsored REITs, which
agreement was amended March 10, 2005 to extend the termination date from March
31, 2005 to May 15, 2005. The Company expects to consummate the mergers on April
30, 2005. As preferred stockholders in certain of these Sponsored REITs, Messrs.
McGillicuddy and Silverstein will receive 80,386 and 1,022,217 shares of the
Company's Common Stock, respectively, upon the consummation of these mergers.

      FSP Investments, a wholly owned subsidiary of the Company, provides
syndication and real estate acquisition advisory services for the Sponsored
REITs. Fees from Sponsored REITs for property acquisition services amounted to
approximately $2,117,000 for the year ended December 31, 2004. As of March 14,
2005, fees from Sponsored REITs during 2005 amounted to approximately $254,000.
Sales commissions earned from the sale of Sponsored REIT preferred shares
amounted to approximately $13,579,000 for the year ended December 31, 2004. As
of March 14, 2005, sales commissions from the sale of Sponsored REIT preferred
shares during 2005 amounted to approximately $2,068,000.

      During 2004 and 2005, the Company provided interim financing for the
purchase of certain Sponsored REIT properties prior to completion of the
Sponsored REITs' private equity offerings. The Sponsored REITs paid the Company
financing commitment fees of approximately $11,976,000 for the year ended
December 31, 2004. As of March 14, 2005, the Company received approximately


                                       16


$1,770,000 in financing commitment fees from the Sponsored REITs during 2005.
Interest income earned from loans to the Sponsored REITs amounted to
approximately $964,000 for the year ended December 31, 2004. As of March 14,
2005, the interest income earned from loans to the Sponsored REITs during 2005
amounted to approximately $675,000. The interest rate charged by the Company to
the Sponsored REITs is equal to the interest rate paid by the Company to
Citizens Bank for borrowings under its line of credit. Therefore, the Company
does not realize any significant profit from interest on the loans. All loans to
Sponsored REITs were evidenced by promissory notes and were paid in full upon
closing of the applicable Sponsored REIT's private equity offering during 2004
or 2005. In addition, two loans made to Sponsored REITs during 2004 and 2005
were partially outstanding at March 14, 2005. The following table summarizes
these interim financing transactions from January 1, 2004 through March 14,
2005:

                            SELECTION OF ACCOUNTANTS

      The Audit Committee of the Board of Directors has selected Ernst & Young
LLP as the Company's independent registered public accounting firm for fiscal
2005. Ernst & Young has served as the Company's independent registered public
accounting firm since May 2003. PricewaterhouseCoopers served as the Company's
independent accountants from October 2001 to May 2003.

      Representatives of Ernst & Young are expected to be present at the Annual
Meeting and will have the opportunity to make a statement if they desire to do
so and will be available to respond to appropriate questions from stockholders.

      On May 8, 2003, PricewaterhouseCoopers LLP informed the Company that it
had elected not to stand for re-election as the Company's independent certified
public accountant. The reports of PricewaterhouseCoopers LLP on the Company's
financial statements for the fiscal years ended December 31, 2001 and 2002 did
not contain an adverse opinion or a disclaimer of opinion, and were not
qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended December 31, 2002 and 2001 and any subsequent
interim period preceding the dismissal, there were (i) no disagreements with
Pricewaterhouse Coopers on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of PricewaterhouseCoopers,
would have caused it to make reference to the subject matter of the
disagreements in connection with its reports and (ii) no reportable events as
defined in Regulation S-K Item 304(a)(1)(iv). Because PricewaterhouseCoopers
resigned on May 8, 2003, PricewaterhouseCoopers did not make any representations
as to the Company's financial statements for the fiscal years ended December 31,
2003 and December 31, 2004 and there were no disagreements or reportable events
during the fiscal years ended December 31, 2003 and December 31, 2004.

      The Company solicited proposals from various accounting firms and
following review of such proposals engaged Ernst & Young to act as the Company's
independent registered public accounting firm effective May 8, 2003. During the
fiscal year ended December 31, 2002 and any subsequent interim period preceding
the engagement, the Company did not consult Ernst & Young regarding the
application of accounting principles to a specified transaction, either
completed or proposed, or the type of audit opinion that might be rendered on
the Company's financial statements, or any matter that was the subject of a
disagreement or a reportable event.

Report of the Audit Committee of the Board of Directors

      The Audit Committee of the Company's Board of Directors acts under a
written charter first adopted and approved in January 2002. In October 2004 the
Audit Committee amended and restated its charter. The amended and restated
charter is attached to this proxy statement as Appendix A.

      The Audit Committee reviewed the Company's audited consolidated financial
statements for the year ended December 31, 2004 and discussed these consolidated
financial statements with the Company's management and the Company's independent
registered public accounting firm. Management is responsible for the preparation
of the Company's consolidated financial statements, internal controls, and for
the appropriateness of accounting principles used by the Company. The Company's
independent registered public accounting firm is responsible for performing an
independent audit of the Company's consolidated financial statements in
accordance with the standards of the Public Company Accounting Oversight Board
(United States) and issuing a report on those consolidated financial statements,
performing an independent audit in accordance with the standards of the Public
Company Accounting Oversights Board (United States) of Management's assessment
over the effectiveness of the Company's internal control over financial
reporting and performing an independent audit of the effectiveness of the
Company's internal control over financial reporting and issuing a report on the
results of their audits, and for reviewing the Company's unaudited interim
consolidated financial statements. As appropriate, the Audit Committee reviews
and evaluates, and discusses with the Company's management, internal accounting,
financial and auditing personnel and the independent registered public
accounting firm, the following:

      o     the plan for, and the independent auditors' report on, each audit of
            the Company's financial statements;

      o     the Company's financial disclosure documents, including all
            financial statements and reports filed with the Securities and
            Exchange Commission or sent to stockholders;

      o     management's selection, application and disclosure of critical
            accounting policies;

      o     changes in the Company's accounting practices, principles, controls
            or methodologies;

      o     significant developments or changes in accounting rules applicable
            to the Company; and

      o     the adequacy of the Company's internal controls and accounting,
            financial and auditing personnel.

      The Audit Committee also reviewed and discussed the audited consolidated
financial statements and the matters required by Statement on Auditing Standards
61 (Communication with Audit Committees) with Ernst & Young LLP, the Company's
independent registered public accounting firm for the year ended December 31,
2004. SAS 61 requires the Company's independent registered public accounting
firm to discuss with the Company's Audit Committee, among other things, the
following:


                                       19


      o     methods to account for significant unusual transactions;

      o     the effect of significant accounting policies in controversial or
            emerging areas for which there is a lack of authoritative guidance
            or consensus;

      o     the process used by management in formulating particularly sensitive
            accounting estimates and the basis for the auditors' conclusions
            regarding the reasonableness of those estimates; and

      o     disagreements with management over the application of accounting
            principles, the basis for management's accounting estimates and the
            disclosures in the financial statements.

      The Company's independent registered public accounting firm also provided
the Audit Committee with the written disclosures and the letter required by
Independence Standards Board Standard No. 1 (Independence Discussions with Audit
Committees). Independence Standards Board Standard No. 1 requires auditors
annually to disclose in writing all relationships that in the auditor's
professional opinion may reasonably be thought to bear on independence, confirm
their perceived independence and engage in a discussion of independence. The
Audit Committee discussed with the independent registered public accounting firm
the matters disclosed in this letter and their independence from the Company.
The Audit Committee also considered whether the independent auditors' provision
of the other, non-audit related services which are referred to under the heading
"Independent Auditor Fees and Other Matters" is compatible with maintaining such
auditor's independence.

      Based on its discussions with management and the independent registered
public accounting firm, and its review of the representations and information
provided by management and the independent registered public accounting firm,
the Audit Committee recommended to the Company's Board of Directors that the
audited consolidated financial statements be included in the Company's Annual
Report on Form 10-K for the year ended December 31, 2004.

      By the Audit Committee of the Board of Directors of Franklin Street
Properties Corp.

                                                    ========           ========

            statements, the review of the interim financial statements included
            in our quarterly reports on Form 10-Q, and other professional
            services provided in connection with statutory and regulatory

      (2)   Audit-related fees consist of fees for assurance and related
            services that are reasonably related to the performance of the audit
            and the review of our financial statements and which are not
            reported under "Audit Fees".

            planning services. Tax compliance services, which relate to the
            preparation of tax returns, claims for refunds and tax

            fees incurred in 2004, and accounted for $6,000 of the total tax
            fees incurred in 2003.

Pre-Approval Policy and Procedures

      The Audit Committee has adopted policies and procedures relating to the
approval of all audit and non-audit services that are to be performed by the
Company's independent registered public accounting firm. This policy generally
provides that the Company will not engage its independent registered public
accounting firm to render audit or non-audit services unless the service is
specifically approved in advance by the Audit Committee or the engagement is
entered into pursuant to one of the pre-approval procedures described below.

      From time to time, the Audit Committee may pre-approve specified types of
services that are expected to be provided to the Company by its independent
registered public accounting firm during the next 12 months. Any such
pre-approval is detailed as to the particular service or type of services to be
provided and is also generally subject to a maximum dollar amount.

      The Audit Committee has also delegated to each individual member of the
Audit Committee the authority to approve any audit or non-audit services to be
provided to the Company by its independent registered public accounting firm.
Any approval of services by a member of the Audit Committee pursuant to this
delegated authority is reported on at the next meeting of the Audit Committee.

                             STOCK PERFORMANCE GRAPH

         The following graph compares the cumulative total stockholder return on
the Company's Common Stock (or, prior to January 1, 2002, units ("FSP Units") of
the Partnership) between December 31, 1999 and December 31, 2004 with the
cumulative total return of (1) the Russell 2000 Total Return Index, (2) the
Standard & Poor's 500 Composite Stock Price Index ("S&P 500") and (3) the Morgan
Stanley REIT Index over the same period. This graph assumes the investment of
$100.00 on December 31, 1999 in FSP Units of the Partnership's limited
partnership interests and assumes any distributions are reinvested. Each FSP
Unit was converted into one share of Common Stock on January 1, 2002.

                                       22


Notes to Graph:

(1)   Because there was no market for FSP Units, the price per FSP Unit used in
      the calculations set forth above for December 31, 1999 and December 31,
      2000 is the price ascribed to an FSP Unit in equity-for-equity mergers
      consummated by the Partnership on January 1, 2000, and October 1, 2000,
      respectively, and the price set forth above for December 31, 2001 is the
      price ascribed to an FSP Unit in the Conversion. The price ascribed to the
      FSP Units for the mergers took into account, among other factors, the lack
      of a trading market.

(2)   Because there was no market for the Company's Common Stock, the Board of
      Directors has made a good faith determination of the price per share of
      Common Stock as of December 31, 2002, December 31, 2003 and December 31,
      2004 for purposes of the calculations set forth above. In order to make
      the Common Stock price more comparable to publicly traded indices, the
      Board of Directors has not applied any discount to reflect the lack of a
      trading market.

                                  OTHER MATTERS

Matters to be Considered at the Meeting

      The Board of Directors does not know of any other matters which may come
before the Annual Meeting. However, if any other matters are properly presented
to the Annual Meeting, it is the intention of the persons named in the
accompanying proxy to vote, or otherwise act, in accordance with their judgment
on such matters.

Solicitation of Proxies

      All costs of solicitation of proxies will be borne by the Company. In
addition to solicitations by mail, the Company's directors, officers and
employees, without additional remuneration, may solicit proxies by telephone,
telegraph and personal interviews. Brokers, custodians and fiduciaries will be
requested to forward proxy soliciting material to the owners of stock held in
their names, and, as required by law, the Company will reimburse them for their
out-of-pocket expenses in this regard.

Stockholder Proposals

      Proposals of stockholders intended to be included in the Company's proxy
statement for the 2006 Annual Meeting of Stockholders must be received by the
Company at its principal office not later than November 29, 2005.

      If a stockholder who wishes to make a proposal at the 2006 Annual
Meeting--other than one that will be included in the Company's proxy
materials--does not notify the Company by no earlier than November 29, 2005 and
no later than December 29, 2005, the proxies that management solicits for the
meeting will have discretionary authority to vote on the stockholder's proposal
if it is properly brought before the meeting.

Important Notice Regarding Delivery of Security Holder Documents

      The Company participates in the practice of "householding" proxy
statements and annual reports, meaning that the Company delivers a single proxy
or information statement to a household, even though two or more stockholders
live under the same roof or a stockholder has shares registered in multiple
accounts, unless the Company has received an instruction to the contrary from
one or more of the stockholders. This practice enables the Company to reduce the
expense of printing and mailing associated with proxy statements and reduces the
amount of duplicative information a stockholder may currently receive.

      The Company will promptly deliver a separate copy of either document to a
stockholder if a stockholder calls or writes to the Company at the following
address or phone number: Franklin Street Properties Corp., 401 Edgewater Place,
Suite 200, Wakefield, Massachusetts 01880, (781) 557-1300. If a stockholder
wants to receive separate copies of the annual report and proxy statement in the
future, or if the stockholder is receiving multiple copies and would like to
receive only one copy for his or her household, said stockholder should contact
the Company at the above address and phone number.

                                  By Order of the Board of Directors,


                                  Barbara J. Fournier, Secretary

March 29, 2005

      The Board of Directors hopes that stockholders will attend the meeting.
Whether or not you plan to attend, you are urged to complete, date, sign and
return the enclosed Proxy in the accompanying envelope. Prompt response will
greatly facilitate arrangements for the meeting and your cooperation will be
appreciated. Stockholders who attend the meeting may vote their stock personally
even though they have sent in their proxies.

C.    Authority and Responsibilities

      General

      The Audit Committee shall discharge its responsibilities, and shall assess
      the information provided by the Company's management and the independent
      auditor, in accordance with its business judgment. Management is
      responsible for the preparation, presentation, and integrity of the
      Company's financial statements and for the appropriateness of the
      accounting principles and reporting policies that are used by the Company.
      The independent auditors are responsible for auditing the Company's
      financial statements and for reviewing the Company's unaudited interim
      financial statements. The authority and responsibilities set forth in this
      Charter do not reflect or create any duty or obligation of the Audit
      Committee to plan or conduct any audit, to determine or certify that the
      Company's financial statements are complete, accurate, fairly presented,
      or in accordance with generally accepted accounting principles or
      applicable law, or to guarantee the independent auditor's report.

      Oversight of Independent Auditors

      1.    Selection. The Audit Committee, as the representatives, with the
            Board of Directors of the Company, of the shareholders of the
            Company, shall be solely and directly responsible for appointing,
            evaluating and, when necessary, terminating the independent auditor.
            The Audit Committee may, in its discretion, seek stockholder
            ratification of the independent auditor it appoints.

      2.    Independence. The Audit Committee shall take, or recommend that the
            full Board of Directors take, appropriate action to oversee the
            independence of the independent auditor. In connection with this
            responsibility, the Audit Committee shall obtain and review a formal
            written statement from the independent auditor describing all
            relationships between the independent auditor and the Company,
            including the disclosures required by Independence Standards Board
            Standard No. 1. The Audit Committee shall actively engage in
            dialogue with the independent auditor concerning any disclosed
            relationships or services that might impact the objectivity and
            independence of the auditor.

      3.    Compensation. The Audit Committee shall have sole and direct
            responsibility for setting the compensation of the independent
            auditor. The Audit Committee is empowered, without further action by
            the Board of Directors, to cause the Company to pay the compensation
            of the independent auditor established by the Audit Committee.


                                      A-2


      4.    Preapproval of Services. The Audit Committee shall preapprove all
            audit services, which may entail providing comfort letters in
            connection with securities underwritings, and non-audit services
            (other than de minimus non-audit services as defined by the
            Sarbanes-Oxley Act of 2002 (and the applicable rules thereunder)) to
            be provided to the Company by the independent auditor. The Audit
            Committee shall cause the Company to disclose in its SEC periodic
            reports the approval by the Audit Committee of any non-audit
            services to be performed by the independent auditor.

      5.    Oversight. The independent auditor shall report directly to the
            Audit Committee and the Audit Committee, as the representatives,
            with the Board of Directors of the Company, of the shareholders of
            the Company, shall have sole and direct responsibility for
            overseeing the independent auditor, including resolution of
            disagreements between Company management and the independent auditor
            regarding financial reporting. In connection with its oversight
            role, the Audit Committee shall, from time to time as appropriate
            obtain and review the reports required to be made by the independent
            auditor pursuant to paragraph (k) of Section 10A of the Securities
            Exchange Act of 1934 regarding:

            -     critical accounting policies and practices;

            -     alternative treatments of financial information within
                  generally accepted accounting principles that have been
                  discussed with Company management, ramifications of the use of
                  such alternative disclosures and treatments, and the treatment
                  preferred by the independent auditor; and

            -     other material written communications between the independent
                  auditor and Company management.

      6.    Quality-Control Report. At least annually, the Audit Committee shall
            obtain and review a report by the independent auditor describing:

            -     the firm's internal quality control procedures; and

            -     any material issues raised by the most recent internal
                  quality-control review, or peer review, of the firm, or by any
                  inquiry or investigation by governmental or professional
                  authorities, within the preceding five years, respecting one
                  or more independent audits carried out by the firm, and any
                  steps taken to deal with any such issues.

            included in the Company's Annual Report on Form 10-K.

      9.    Audit Committee Report. The Audit Committee shall prepare for
            inclusion where necessary in a proxy or information statement of the

            review of interim financial information which are required to be
            discussed by Statement on Auditing Standards Nos. 61, 71 and 90. The
            Audit Committee shall direct management to advise the Audit
            Committee in the event that the Company proposes to disclose interim

            provided to analysts, rating agencies and others.
